Disjunctivism, as a theory of visual experience, claims that the mental states involved in a “good case” experience of veridical perception and a “bad case” experience of hallucination differ, even in those cases in which the two experiences are indistinguishable for their subject. Consider the veridical perception of a bar stool and an indistinguishable hallucination; both of these experiences might be classed together as experiences (as) of a bar stool or experiences of seeming to see a bar stool. This might (...) lead us to think that the experiences we undergo in the two cases must be of the same kind, the difference being that the former, but not the latter, is connected to the world in the right kind of way. Such a conjecture has been called a “highest common factor” or “common kind” assumption. At heart, disjunctivism consists in the rejection of this assumption. According the disjunctivist, veridical experiences and hallucinations do not share a common component. There are a host of interesting questions surrounding disjunctivism including: What is involved in the claims that good case and bad case experiences differ? Why might one might want to be a disjunctivist? What kinds of claims can the disjunctivist make about hallucination and illusion? These questions, and problems for the thesis, will be discussed as we proceed. (shrink)

In company with its sister volume, Arts-Based Research Across Textual Media in Education explores arts-based approaches to research across media, including film and comics-related material, from a variety of geographic locations and across a range of sub-disciplines within the field of education. This first volume takes a textual focus, capturing process, poetic, and dramaturgical approaches. The authors aim to highlight some of the approaches that are not always centered in arts-based research. The contributors represent a variety of arts-based practices and (...) methods, and they weave this marrying of artistic and scientific expertise and experience into the fabric of the chapters themselves. Authors from international contexts speak to the importance of utilizing artistic approaches for research processes. From multimodal field notes to poetic forms to the dramaturgical, chapters in this book represent steps forward in educational inquiry to bringing together both the creative and credible. The book includes multiple images and rich descriptions shared from the field. This first volume covers amongst other topics: co-created narratives; creative fiction in research; analytic portraits; dramatic representation, and critical poetic inquiry. It would be suitable for graduate students and scholars interested in qualitative inquiry and arts-based methods, in Education and the social sciences. (shrink)

There is a long history of cryptographic hash functions, i.e. functions mapping variable-length strings to fixed-length strings, and such functions are also expected to enjoy certain security properties. Hash functions can be effected via modular arithmetic, permutation-based schemes, chaotic mixing, and so on. Herein we introduce the notion of an artificial-life (ALife) hash function (ALHF), whereby the requisite mixing action of a good hash function is accomplished via ALife rules that give rise to complex evolution of (...) a given system. Various security tests have been run, and the results reported for examples of ALHFs. (shrink)

We show how to formalize approximate counting via hash functions in subsystems of bounded arithmetic, using variants of the weak pigeonhole principle. We discuss several applications, including a proof of the tournament principle, and an improvement on the known relationship of the collapse of the bounded arithmetic hierarchy to the collapse of the polynomial-time hierarchy.

The goal of this paper is to answer the following question: When we have mental states that represent certain things as being colored, what properties are our mental states representing these things as having?

Since digital forensics becomes more and more popular, more and more attention has been paid to the originality and validity of data, and data preservation technology emerges as the times require. However, the current data preservation models and technologies are only the combination of cryptography technology, and there is a risk of being attacked and cracked. And in the process of data preservation, human participation is also needed, which may lead to data tampering. To solve problems given, this paper presents (...) a data preservation model based on blockchain and multidimensional hash. With the decentralization and smart contract characteristics of blockchain, data can be automatically preserved without human participation to form a branch chain of custody in the unit of case, and blockchain has good antiattack performance, which is the so-called 51% attack. Meanwhile, in order to solve the problem of data confusion and hard to query caused by the excessive number of cases, hash, cryptography, and timestamps are used to form a serialized main chain of custody. Because of the confliction problem of hash and judicial trial needs to absolutely guarantee the authenticity and validity of data, multidimensional hash is used to replace regular hash. In this way, the data preservation becomes an automatic, nonhuman-interventional process. Experiments have been carried out to show the security and effectiveness of the proposed model. (shrink)

Databases play a fundamental role in today’s world, being used by most companies, especially those that offer services through the Internet. Today there is a wide variety of database models, each adapted for use according to the specific requirements of each application. Traditionally, the relational models with centralized architectures have been used mostly due to their simplicity and general-purpose query language, which made relational systems suitable for almost any application. However, with the growth of the Internet in recent decades, both (...) in the number of users and in the amount of information, those centralized models began to suffer availability and scalability issues. To address those issues, the use of decentralized architectures and alternative database models began to arise, eventually replacing relational databases and centralized architectures when the requirements on availability and scalability are high. Those database models alternative to the traditional relational model are grouped under the name of NoSQL. In this article, we present a NoSQL database developed as an end of degree work, with a flexible data model based on documents and a fully decentralized architecture based on the Gossip protocol for node discovery and a distributed hash table, in particular the rendezvous hashing algorithm, used to distribute and replicate the data across all the nodes. The main goals of the system are to achieve high availability and high scalability. High availability is achieved thanks to the replication of the data, while high scalability is achieved by its decentralized architecture, which allows multiple entry points from the requests, and the data distribution, effectively increasing the database capacity by increasing the number of nodes.

The text of “The Four Premises” (Muqaddimāt al-Arba‘a), which began with Sadr al-Sharī‘ah (d. 747/1346), centralizes on the actions of human beings by connecting it with the problem of good and evil in the field of kalām, Islamic philosophy and logic, and fıqh. It was also commented in with incisive and critical footness by Sa‘d al-Dīn al-Taftāzānī (d. 791/1390). In Ĥāshiya ‘alā Muqaddimāt al-Arba‘a, al-Kastalī (d. 901/1496) discusses the two main issues. One of them is good/husn-evil/qubh, the other is human (...) actions. Good-evil dichotomy here is axiological, whereas the human actions are examined within an ontological structure. The quest for the origin of moral values is a husn-qubh debate. Identifying the hierarchy of human actions in ontology is another problem. The main purpose of this study is to investigate the theological discussions in the Ĥāshiya ‘alā Muqaddimāt al-Arba‘a which were written following the order of Sultan Mehmed the Conqueror/Fatih. This text addresses the origin of moral judgment and the question of freedom and destiny in human actions linked to the problem of good and evil. Discussing these two fundamental issues, has made it necessary to thoroughly investigate perhaps all the subheadings which concern the entire paradigm that falls under the framework of understanding the God, nature, and humanity. By looking at the treatise, the main sources of the issues being discussed are mostly generated from an Islamic jurisprudence works, entitled Tawḍīḥ and Talwīḥ. It can easily be discerned that the direct quotations that were made or taken indirectly were from these two sources. References to other sources were quite seldom. However, the excerpts that were taken from primary sources were interpreted and expounded by the author and amended anew. In this article al-Kastalī’s comments will be analyzed. He’s work Ĥāshiya ‘alā Muqaddimāt al-Arba‘a will be analyzed in depth and will be published for the first time with a critical edition. Text of Muqaddimāt al-Arba‘a is a product of a culture of criticism and critical thinking has two foundations: Disproval and verification. Critical thinking is then bidirectional. It is wrong to carry out the criticism activity in only one direction. It is insufficient to simply refute the opposing idea. It is not enough to show the wrong. The so-called right idea also needs to be justified. In the Tawdīh, Sadr al-Sharī‘ah criticizes al-Ashʿarī in the issues of husn-qubh and human actions. According to this criticism, good and evil should be based on the reason. On the other hand, human is free in his actions. As it is known, goodness and badness was based on religion according to al-Ashʿarī. Acquisition (kasb) given to man was unclear. It is al-Taftāzānī who wrote an annotation on Tawḍīḥ with the name of Talwīḥ. He’s comments are successful in terms of theology. However, these interpretations do not mean that he accepted the Muqaddimāt al-Arba‘a. In terms of al-Taftāzānī, proofs of Sadr al-Sharī‘ah is weak. The theological disputes in Tawḍīḥ and Talwīḥ have reached the level of tension in the following works. The origins of the divergence are based on the differentiation between the schools of al-Māturīdi and al-Ashʿarī. In fact, these schools are not different from each other in terms of the method they use. Although the roads walked were the same, the results achieved were different. The main reason for this is that the issue is ambiguous and the problem of good and evil is multidimensional. It is directly related to God and human. It is also connected with ontology and epistemology together. The position on the husn-qubh issue is also decisive for other theological problems. The root of the evil problem or theodicy is mostly based on this problem in Islamic thought. The actions of God and human are questioned here. The value judgments that actions will take are examined. Which action is more moral and better? Another major problem discussed in this article is human actions. It is a matter of freedom of human volition. The volition of man before the absolute God is a problem. Because God has absolute power, will and knowledge. On the other hand, God imposes responsibility on man. But what are the limits of this responsibility? Al-Kastalī discusses all these problems in the context of Sadr al-Sharī‘ah and al-Taftāzānī. In the big picture there are representatives of the schools of al-Māturīdi and al-Ashʿarī. Al-Kastalī doesn’t paint a new picture, rather makes the lines in the picture clear. In this article, the texts will be analyzed mutually. The content and uses of the concepts will be given importance. Ideas will be discussed from their main sources and the roots and different reach of the issues will be touched. The interactions of different schools of thought will also be included. (shrink)

Justin makes a novel case, based on reflection on the “telos” of color vision, for a dispositional theory of colors.

Legal information certification and secured storage combined with documents electronic signature are of great interest when digital documents security and conservation are in concern. Therefore, these new and evolving technologies offer powerful abilities, such as identification, authentication and certification. The latter contribute to increase the global security of legal digital archives conservation and access. However, currently used cryptographic and hash coding concepts cannot intrinsically enclose cognitive information about both the signer and the signed content. Indeed, an evolution of these (...) technologies may be necessary to achieve full text researches within hundreds or thousands of electronically signed documents. This article aims at describing a possible model along with associated processes to create and make use of these new electronic signatures called “meaningful electronic signatures” as opposed to traditional electronic signatures based on bit per bit computation.

Internalists about reasons following Bernard Williams claim that an agent’s normative reasons for action are constrained in some interesting way by her desires or motivations. In this paper, I offer a new argument for such a position—although one that resonates, I believe, with certain key elements of Williams’ original view. I initially draw on P.F. Strawson’s famous distinction between the interpersonal and the objective stances that we can take to other people, from the second-person point of view. I suggest that (...) we should accept Strawson’s contention that the activity of reasoning with someone about what she ought to do naturally belongs to the interpersonal mode of interaction. I also suggest that reasons for an agent to perform some action are considerations which would be apt to be cited in favor of that action, within an idealized version of this advisory social practice. I then go on to argue that one would take leave of the interpersonal stance towards someone—thus crossing the line, so to speak—in suggesting that she do something one knows she wouldn’t want to do, even following an exhaustive attempt to hash it out with her. An internalist necessity constraint on reasons is defended on this basis. (shrink)

As government pressure on major technology companies builds, both firms and legislators are searching for technical solutions to difficult platform governance puzzles such as hate speech and misinformation. Automated hash-matching and predictive machine learning tools – what we define here as algorithmic moderation systems – are increasingly being deployed to conduct content moderation at scale by major platforms for user-generated content such as Facebook, YouTube and Twitter. This article provides an accessible technical primer on how algorithmic moderation works; examines (...) some of the existing automated tools used by major platforms to handle copyright infringement, terrorism and toxic speech; and identifies key political and ethical issues for these systems as the reliance on them grows. Recent events suggest that algorithmic moderation has become necessary to manage growing public expectations for increased platform responsibility, safety and security on the global stage; however, as we demonstrate, these systems remain opaque, unaccountable and poorly understood. Despite the potential promise of algorithms or ‘AI’, we show that even ‘well optimized’ moderation systems could exacerbate, rather than relieve, many existing problems with content policy as enacted by platforms for three main reasons: automated moderation threatens to further increase opacity, making a famously non-transparent set of practices even more difficult to understand or audit, further complicate outstanding issues of fairness and justice in large-scale sociotechnical systems and re-obscure the fundamentally political nature of speech decisions being executed at scale.

Facial expression recognition plays a significant part in artificial intelligence and computer vision. However, most of facial expression recognition methods have not obtained satisfactory results based on low-level features. The existed methods used in facial expression recognition encountered the major issues of linear inseparability, large computational burden, and data redundancy. To obtain satisfactory results, we propose an innovative deep learning model using the kernel entropy component analysis network and directed acyclic graph support vector machine. We use the KECANet in the (...) feature extraction stage. In the stage of output, binary hashing and blockwise histograms are adopted. We sent the final output features to the DAGSVM classifier for expression recognition. We test the performance of our proposed method on three databases of CK+, JAFFE, and CMU Multi-PIE. According to the experiment results, the proposed method can learn high-level features and provide more recognition information in the stage of training, obtaining a higher recognition rate.

This chapter investigates the prospects for an important position that falls under the "mere patterns" approach: what, for reasons that will emerge, the author calls"Humean reductionism" about laws of nature, a view championed perhaps most prominently by David Lewis. He reviews some of the most interesting arguments against this position from the literature, and adds some of his own that, he thinks, are more effective. The chapter considers how the best system account (BSA) would apply to the Newtonian particle world. (...) The BSA has been challenged in a wide variety of ways: it violates certain intuitions; It makes a hash out of the connection between laws on the one hand, and counterfactuals, explanation, and induction on the other. The author thinks that the problem he has raised‐challenging though he hopes it is, is really an occasion for the Humean reductionist to sharpen his position still further. (shrink)

Thomas Aquinas’ account of religious vocation has been interpreted as involving a qualified duty, where ordinary people fall short of living up to the moral ideal of becoming a monk or nun. Such an account of religious vocation makes a hash of Aquinas’ thought and misses important aspects of his ethics. Aquinas holds that religious life is praiseworthy, but not morally required, because there are multiple sources of normativity. I conclude by proposing that, while elements of Aquinas’ notion of (...) supererogation might be shared with other traditions in virtue ethics, his theological commitments are central to his notion of supererogation.

Visual cryptography is a cryptographic technique that allows visual information to be encrypted so that the human optical system can perform the decryption without any cryptographic computation. The halftone visual cryptography scheme (HVCS) is a type of visual cryptography (VC) that encodes the secret image into halftone images to produce secure and meaningful shares. However, the HVC scheme has many unsolved problems, such as pixel expansion, low contrast, cross-interference problem, and difficulty in managing share images. This article aims to enhance (...) the visual quality and avoid the problems of cross-interference and pixel expansion of the share images. It introduces a novel optimization of color halftone visual cryptography (OCHVC) scheme by using two proposed techniques: hash codebook and construction techniques. The new techniques distribute the information pixels of a secret image into a halftone cover image randomly based on a bat optimization algorithm. The results show that these techniques have enhanced security levels and make the proposed OCHVC scheme more robust against different attacks. The OCHVC scheme achieves mean squared error (MSE) of 95.0%, peak signal-to-noise ratio (PSNR) of 28.3%, normalized cross correlation (NCC) of 99.4%, and universal quality index (UQI) of 99.3% on average for the six shares. Subsequently, the experiment results based on image quality metrics show improvement in size, visual quality, and security for retrieved secret images and meaningful share images of the OCHVC scheme. Comparing the proposed OCHVC with some related works shows that the OCHVC scheme is more effective and secure. (shrink)

We live in the era of Facebook, Fitbit, and Skype. As such, it would be unreasonable to expect that the healthcare industry would not see the same kind of globalization as do our social spheres and consumer activities. Indeed, the explosion of information technology, the ease of transcontinental travel, and the emergence of a more globally aware citizenry allows for scientific collaboration that has had many positive effects on global health. However, the economic and structural disparities between systems of healthcare (...) delivery in the industrialized world and parts of the developing world have created a monster in the form of an international medical tourism industry that endangers the health and safety of citizens of the host country as well as visiting patients. Not only does the practice of medical tourism pose a practical danger to those in direct contact with the industry, but it brings up troubling philosophical problems centering on national responsibility and the commodification of healthcare, among other important issues. In the United States, the driving force behind international medical tourism is the exorbitant cost of healthcare, particularly for the uninsured but also for the underinsured and those who experience catastrophic medical expenses from chronic illness or sudden health crises. Not only have individuals begun to look outside the U.S. for surgical procedures and other expensive therapies, but employers have begun to toy with the idea of outsourcing the medical care of the employees they insure in order to cut costs. In other industrialized nations, the issues that underpin international medical tourism are related to healthcare rationing and reflect different shortcomings in the delivery of healthcare in those nations, such as the United Kingdom and Canada, that have single-payer systems. Yet the regulatory and philosophical implications for both patients and hosts of international healthcare are largely the same. The challenge of regulating international trade in medical care is obvious and becomes particularly acute when there are insurers and employers involved. Complicating matters further, medical care that takes place outside the country of origin of the patient is often brokered by “medical concierge services,” which, though quick to claim indemnity from any harm arising from substandard or inappropriate medical care, cannot be divorced from responsibility for the health outcomes of their clients. Agreements hashed out between concierge services and patients specify that any remedy for harm stemming from their medical care must be pursued within the confines of the law of the host country, but the practical implications of this are troublesome. How can a foreign patient—often without either linguistic or cultural competency in the host country—be expected to navigate the complexity of a foreign legal system, particularly one that may be far less developed than his home country? Furthermore, if insurance companies and employers are involved with such care, who pays for an adverse result or determines responsibility for harm that may befall the patient? Under which countries’ laws? If a patient travels to Singapore for sexual reassignment surgery or a cardiac valve repair, returns to the States and suffers complications, who pays for the restoration of her health? Beyond legal standards and judicial remedies for harm to patients seeking care on the international market, there is the question of what ethical standards and norms apply to such patients. What effect does it have on American patients, for example, to receive care within a system that does not emphasize autonomy and informed consent the way they are used to? Why should foreign physicians care about the cultural mores of their patients’ country of origin? Can they be expected to grasp cultural differences between American, Canadian, and British patients? The medical concierge might respond, “Well, buyer beware!” This is unreasonable: It is nearly impossible for any patient to accurately assess the various options, risks and benefits that go with a particular medical treatment, much less the patient who is attempting to do so on the international market. And the crass invocation of the doctrine of caveat emptor betrays a view of healthcare as a commodity that is naive and inappropriate. Paramount in my mind, however, are the practical implications for the care of the citizens of developing nations that host international patients and the broader philosophical issue of what the goals of the medical profession as a whole and each country’s individual healthcare system should be. While I understand the argument that international medical tourism creates great economic gains for developing nations, which can then be channeled toward the care of their citizenry as a whole, there is much reason to doubt that this “trickle-down” model of economics provides real benefits for underserved, whether in healthcare or other arenas. What is more likely is that, while lucrative international “medi-cities” may keep bright doctors in their home countries, it is also likely to lure them away from the institutions that serve the lion’s share of their countrymen. With the concentration of talented native doctors in private hospitals that serve citizens of the developed world, the population at large is left to obtain care at institutions that suffer “brain drain” from the flight of talented local staff to more prestigious, often “brand name,” institutions that give them more Western-like salaries while allowing them to practice in their countries of origin. The very fact that citizens of the wealthiest nations in the world are forced to go abroad for life-saving care speaks to an abdication of national responsibility on the part of their home countries. The provision of health care is one of the principal responsibilities of any nation and it is unacceptable that a nation with the strength and wealth of the United States would take advantage of the weaker political and economic situations of developing nations in order to shirk its responsibility to its fellow citizens. If we take care of our countrymen and take pride in an equitable system of healthcare delivery, there will be no need to shrug our shoulders and say “Buyer beware” to the patient who heads to the Philippines for heart surgery.

Journal of Mathematical Logic, Volume 22, Issue 03, December 2022. We study a new class of NP search problems, those which can be proved total using standard combinatorial reasoning based on approximate counting. Our model for this kind of reasoning is the bounded arithmetic theory [math] of [E. Jeřábek, Approximate counting by hashing in bounded arithmetic, J. Symb. Log. 74(3) (2009) 829–860]. In particular, the Ramsey and weak pigeonhole search problems lie in the new class. We give a purely computational (...) characterization of this class and show that, relative to an oracle, it does not contain the problem CPLS, a strengthening of PLS. As CPLS is provably total in the theory [math], this shows that [math] does not prove every [math] sentence which is provable in bounded arithmetic. This answers the question posed in [S. Buss, L. A. Kołodziejczyk and N. Thapen, Fragments of approximate counting, J. Symb. Log. 79(2) (2014) 496–525] and represents some progress in the program of separating the levels of the bounded arithmetic hierarchy by low-complexity sentences. Our main technical tool is an extension of the “fixing lemma” from [P. Pudlák and N. Thapen, Random resolution refutations, Comput. Complexity, 28(2) (2019) 185–239], a form of switching lemma, which we use to show that a random partial oracle from a certain distribution will, with high probability, determine an entire computation of a [math] oracle machine. The introduction to the paper is intended to make the statements and context of the results accessible to someone unfamiliar with NP search problems or with bounded arithmetic. (shrink)

This paper introduces and describes new protocols for proving knowledge of secrets without giving them away: if the verifier does not know the secret, he does not learn it. This can all be done while only using one-way hash functions. If also the use of encryption is allowed, these goals can be reached in a more efficient way. We extend and use the GNY authentication logic to prove correctness of these protocols.

Photo by Jonathan Ford on Unsplash ABSTRACT Since 2008, an average of twenty million people per year have been displaced by weather events. Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. This paper analyzes the idea of expanding a duty to rescue to climate migration. We address who should have (...) the duty and to whom the duty should extend. The paper discusses ways to define and apply the duty to rescue as well as its limitations, arguing that it may take the form of an ethical duty to prepare. INTRODUCTION Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. Examples of circumstances range from person-to-person intimate rescue to saving those in poverty, even in distant parts of the world.[1] Since 2008, an average of twenty million people per year have been displaced by weather events.[2] Circumstances like being thrust from homes under the threat of fire, mudslide, and flooding vary greatly from long-term changes like land becoming too arid for crops or temperatures increasing annually gradually pushing up the number of heat-related deaths, with the area slowly becoming uninhabitable. Imminence in fleeing affects resettling and need for rescue with important implications for how the duty to rescue might apply. This paper reevaluates the ethical framing of the duty to rescue and, while it is arguably a stretch, applies it to climate migration. Climate migration has become common and is expected to increase due to rises in sea level, increases in weather events that make areas uninhabitable, and changes to land that preclude farming or other necessary land uses. We argue that a duty to rescue may help highlight who has moral obligations to whom. Because the problem is so large in scope, we suggest a change in the ethical limits to humans' duty to rescue other humans who are in distress. We imagine an expansion or extension of the duty to rescue to meet some of the basic needs created by climate migration. Yet how it should expand, and how much depend on ethical framing and practical limitations. l. Expanding the Geographical Boundaries Two commonly recognized emergencies, Hurricane Katrina in the case of weather events and the current COVID-19 pandemic, provide a historical and current backdrop to evaluate ethical obligations as more disasters displace people. A significant reassessment of the ethical scope of an obligation to rescue in the case of weather events will be limited by the ability to render aid to those in distress in the case of a planet-wide weather catastrophe. The problems may overwhelm the ability to rescue or the reasonableness of attempting rescue. The extent of the moral obligation borne by humans to other humans in the case of a weather event has been largely defined by its locality and limited geographic influence. Whether we are imagining the scope of ethical obligation in the case of hurricane, flood, tornado, drought, or wildfire events, the perceived ethical obligation is significantly defined by the limited impact of these weather events on people outside the zone of the weather event's direct impact, yet close to that zone. A hurricane affecting New Orleans will not have immediate impact on the residents of California or even those on the northeast coast of the United States until a later time. Wildfires in the Pacific Northwest do not impair the ability of those in the rest of the country to come forward with assistance. But as climate migration crosses international borders, and climate events occur simultaneously in many regions, a more expansive duty to rescue may provide the ethical impulse to help those who live afar or migrate long distances. In this respect, the need for help in the event of widespread climate migration due to global warming is more like a pandemic than a weather event. Its broad impact area diminishes the capability of nearly the entire balance of the human population to help due to those populations' awareness that they will, in short order, have the same need for the same resources, from the same cause. Those living near current flood zones may find their historically safe havens are also a flood zone. Those previously best positioned to rescue may find themselves also needing to relocate. Thus, we may observe the need for new rescuers. ll. The Rule of Rescue The Rule of Rescue as defined by Al Jonsen describes the moral impetus or knee jerk reaction to save identifiable people facing death.[3] A duty to rescue has since been expanded beyond imminent death and beyond the near and identifiable. But there are limitations. For example, by most accounts, the ethical duty tends not to require extreme bodily risk or financial depletion. In comparing Good Samaritans to humanitarians, Scott M. James argues the duty to rescue arises from unique dependence, but the ethical obligation to help strangers through humanitarian aid is of a different nature.[4] The wrongness of failing to help is arguably more egregious when one is in a unique position to help. Like in the tragedy of the commons, where there is no unique positioning, when the global community is called upon to help, each individual in it may feel less obliged to do so. Climate migration falls in between—it requires helping strangers, yet it may move forward without anyone seeing themselves as uniquely positioned to help until those strangers become part of communities, at which time, there may be more moral justification to help a community member in need. Generally, arguments about Good Samaritans hinge on extraordinary acts, praiseworthy because they are acts of compassion, not obligation. Now all US states have Good Samaritan laws[5] which protect helpers from liability for help gone wrong or for a failure to succeed once engaged in an act of rescue. Extraordinary help as a moral good is thus somewhat encouraged through legal protection, but not imposed. Conversely, jobs like firefighting, search and rescue, and emergency medical care tend to oblige employees to take on risks that would be extraordinary if undertaken by the average bystander, yet they are rendered ordinary rescue as part of the job. Three states, Minnesota, Rhode Island, and Vermont have a broad duty to rescue, adding legal considerations to an otherwise moral conundrum. The laws do not require bystanders to take on risk for the sake of rescuing strangers.[6] The moral duty will require looking beyond law, but it is unclear how the moral duty to rescue should be distributed in the case of climate migration. A bare minimum would prevent taking advantage of newcomers, paying sub-minimum wage, and discriminating against them. Yet such a minimum is hardly rescue. lll. An Ethical Rather than Legal Duty The difficulty in defining the duty to rescue as a legal obligation is that it is difficult to determine the extent of risk a rescuer ought to be required to take. The nature of this ethical duty is also arguably tied to the experiences of both the rescuer and the rescued. There are subjective aspects like what someone perceives as a danger that make it difficult to write enforceable laws requiring rescue. It is one thing to expect a rescuer to step into several inches of relatively warm water to lift a person lying face down in a pond and enable them to breathe. It is something altogether different to expect that rescuer to dive into frigid water and attempt to extricate someone trapped in a submerged automobile. As the legal philosopher H.L.A. Hart observed, it is always easier to define application of the core intention of any rule, whether law or ethical norm. It is more difficult to create legal certainty about how the law applies to what he described as “penumbra circumstances”. In the case of a hurricane, it is easier to define what surplus resources are available in areas geographically remote from the impact of the storm and demand, as a moral obligation, that those nearby but outside the area provide assistance. It is more difficult to obligate people, organizations, or governments to supply a quantity of medication or some number of ventilators to an adjacent community when they expect to imminently need them for their own community. In the early stages of climate migration, the ethics of extreme weather event assistance, a common application of the duty to rescue, will be useful and appropriate. The rising sea levels first experienced by island nations in the South Pacific[7] will not render those living in other coastal communities, those with greater available “high ground”, unable to supply resources to those in need. But when sea level rise and climate change affect more communities simultaneously, albeit in varying degree, the task of defining what response is ethically obligatory becomes increasingly complicated. Pinpointing the obligations of those communities which are resource rich to those communities which are resource deprived, and of those partly affected to those more severely affected may become necessary. The limitations of the traditional duty to rescue could expand to meet the needs. lV. Contribution to the Problem Many argue that the duty to rescue may depend on any appropriate claim of those needing rescue. One issue is whether preferential claims among those who can identify the source of the harm should call for a greater duty or whether everyone in need should be approached as like candidates for rescue, shaping the duty as equal across those on the receiving end. As climate change does have human-made causes, there are strong arguments to impose a greater ethical duty on any entity that caused the climate-related problems leading to the mass exodus. While the global north is often implicated in pollution that causes migration, industries like energy, transportation, and agriculture are tied to climate change and associated with significant greenhouse gas emissions.[8] Practices like directing agriculture to less sustainable single crop growth generally made land less farmable. Yet it is difficult to place blame and identify specific causal relationships as most migration is due to many factors. A movement toward greater accountability can be reframed as a greater duty to rescue, a duty to engage in the extraordinary. The fossil fuel industry, for example, should have a larger obligation than the average person. Similarly, some may argue anyone unjustly enriching themselves while contributing to climate change or people who over-consume have an elevated duty to rescue.[9] Climate change lawsuits demonstrate an eagerness to hold governments and corporations accountable, despite difficulty proving causation. V. The Most Vulnerable One ethical dimension of climate migration that remains unexplored is how a duty to rescue applies to vulnerable populations who stand to be left behind or unable to migrate without assistance. Researchers from the Global North working across the Global South are increasingly observing the phenomenon of ethics dumping, where the research ethics of some countries are imposed on research subjects in other countries.[10] In that vein, rescuers should be careful not to impose unwelcome cultural standards or exploit people who are in the process of migrating. There is a gap in discussions reflecting voices that have been left out. The duty to rescue is incomplete without an attempt to understand the ethical experiences of those being rescued. The actual people affected by climate migration who are the least likely to have the means to migrate, or to do so without extreme hardship, should have a voice informing the global community including those in a position to carry out rescue. People who have the means and are young and healthy may easily make decisions to avoid the catastrophic consequences that climate migration brings. However, what about those who are left behind? For example, especially recognizing cultural differences, the homeless community, disabled community, refugees, the elderly community, and women[11] and children may suffer differently and call for more attention. In some parts of the world, human rights are severely constrained. An ethical duty to rescue, with many considerations and variables, may be more justified in the case of those most in need. As climate migration continues and increases significantly, it may be reasonable to ask the local and global community to focus on those least well positioned to migrate successfully. In this context, the use of phenomenology to understand the lived experiences of those migrating, sometimes termed “ethical experiences”, may help flesh out how a duty to rescue takes shape. The discussion of duty and obligation requires an articulation of the ethical experiences (how the local community in need of rescue views the proposed rescue). Then, the obligation to interpret the duty as ‘one shall not’ or ‘one must’ can be focused on the migrants’ needs rather than the rescuers’ feelings of obligation.[12] A revised theory of the duty to rescue taking into account the asymmetrical experiences of communities involved could ensure that the needs of people whose living situations, gender, ethnicity, age, or race impact their ability to even begin the migration process are considered. In this discussion, the rescuing is directed toward communities /collectives of persons migrating, whether at once or across a period of time. Often, the climate migrant may not be in a state to articulate the nature of this event when it happens, given its subjective proximity. Yet, when communities are given the space and opportunity to articulate their shared values, the ethical action of rescue derives its meaningfulness from the community rather than the rescuers. In other words, allowing climate migrants to explain their feelings can add complexity to what some see as a binary receiver-giver (of rescue) dynamic. This is necessary because the concept of vulnerable populations is fraught with problematic assumptions. There have been various definitions and criteria to determine what would constitute vulnerable populations.[13] For example, the United Nations Framework Convention on Climate Change[14] identifies and assesses vulnerable populations. These criteria may be helpful. However, they do not provide the full picture. Rather than identifying categorical criteria of vulnerable populations, engaging with people who are experiencing climate migration and listening to their current experiences and concerns helps determine need. Knowing what people need may prevent the kneejerk reaction to label people who are quite resilient yet have appropriate needs “vulnerable”. Proceeding with caution is important because the duty to rescue has hierarchical underpinnings of "us" and "them." Often when people swoop in to save, there are good and bad consequences of the intervention. We should proceed with caution because often the helper misses the actual needs of those in need. The only way to combat this would be to make sure that people are empowered to inform those agencies that are able to help. In addition to more practical approaches, large scale oral histories could allow those who have migrated already to share their experiences. It would be important to capture the lived experiences of people who are already experiencing the consequences of climate migration or of other migration like that due to political or economic extreme events. These experiences could shape our analysis of whether people in fact wish for rescue. If so, further conversations can determine best actions as well as give important insight into what resources might be necessary to empower people now and in the future. Vl. A Duty to Rescue as a Duty to Prepare If we view Good Samaritans as going above and beyond, then a duty to rescue, something ethically compelled, must bring rescue out of the framework of charity and place it in the context of humanity and obligations. Such a view would also support expanding the geographical reach of the otherwise more proximate duty. The duty may be stronger and take shape in a more workable way if it applies to preparing places expecting to see an influx of people due to climate migration and to helping those most in need. The duty may arise out of expectations of what type of community the place welcoming those migrating due to climate should be—does it want to offer good housing, schooling, and medical care as well as economic opportunity to new people? And if so, at what cost, or with which risks? If the newcomers are viewed as community members rather than strangers, a model of acceptance may lead to better preparation. Some considerations like whether the actions will reasonably help the persons in need of rescue[15] will shape the application of a duty to rescue in the context of climate migration. Similarly, ensuring that people have the chance to articulate their values may help communities support the newcomers. New relationships should not be defined as migrant and rescuer. Voluntariness in participation and not forcing any action deemed rescue would help ensure the human rights of those migrating. In the United States, President Biden issued an executive order addressing impending climate migration steeped in a duty to prepare by making plans for resettlement and to address the impact of climate migration.[16] Vll. At What Risk? As we investigate the ethical obligations to meet even basic needs, we must also ask what level of risk is ethically compelled. There is an extraordinary need to integrate newcomers successfully, but it is difficult to stretch an ethical duty to rescue to require all the prerequisites for successful climate migration. Even defining success would create deep ethical arguments. As observed in almost all migrations, extraordinary charitable acts may be the key to success, while an ethical duty to rescue must try to require the important government and community-based basics and ensuring respect for human rights. That is, the migrating people should be rescued from circumstances that contradict basic human rights. Rather than comparing communities to bystanders, mere places where people will arrive and need to hash out how to find housing, jobs, education, and opportunity, a duty of preparation may be the key to rescue those disenfranchised by migration. There are cultural, personal, physical, psycho-social, and geopolitical issues surrounding how to best help those needing to permanently relocate. Ethics arguments will certainly range from “do nothing”, which may fail people, to “do everything”, which could waste taxpayer money in futile over-preparation while failing to actually help. Communities must avoid planning exclusively for one scenario only to have it not take place. Striking the balance, a duty to rescue as it could apply to climate migration should set goals of societal integration, and providing the basics like education, housing, food, health care, and job opportunity, the precursors to flourishing. Recommending the extraordinary, morally preferred but perhaps not compulsory, when charitable actors are participating, or when wrongdoers are compensating, may be more workable than seeing the duty to rescue as compelling people or local governments to take on significant financial and personal risk for newcomers. While humanitarian ethics supports helping everyone, it is likely that people who resettle in advance of a need to flee will find themselves with more choices and opportunities. Help is warranted for those with more dire needs. Preparing for them may do just that. Vlll. Rescue Prior to Migration and Rescue in the Process of Resettlement The duty to enable the migration in the first-place hints to the inadequacy of a duty to prepare. The traditional duty to rescue perhaps steps in if rescue looks like those geographically just out of harm's way rescuing those in danger. That resembles the traditional moral requirement, or duty to rescue according to the Rule of Rescue. Humanitarian aid typically provided by many institutions makes sense and is in place, although financial support for additional humanitarian aid is always needed. Despite having moved to purportedly more capable communities, migrant communities may be able to develop more egalitarian orders of living. Rather than continually being identified as having been rescued, it is important to make sure people keep or make social ties during and after migration. Immigrants often face social isolation.[17] Small shifts in gestural language also have the potential to welcome people and show they are valued. For instance, some migrants may not like questions like “Where are you from?” and “What brings you here?” as they emphasize differences over fitting in. CONCLUSION The ethical duty to rescue should be expanded to better match those in need of relocation with a welcome environment and the resources needed to achieve success and fully integrate socially and culturally. Expanding a dialogue that includes the voices of people who have recently migrated whether due to violence, poverty, or climate, could properly frame the extent of the duty. If we are to apply the duty of rescue to climate migration, rescuers should avoid labeling people vulnerable, dependent, or needy, although there is reason to focus on those whose needs are the most dire. A soft duty to rescue people during the course of climate migration can come in the form of preparation. People will need help finding housing, education, access to food, and employment. Ultimately, to help them help themselves may be the best goal. While the obligations should be borne differently by people, whether due to a special responsibility, or a special relationship that creates a clearer duty, the global community must prepare for its role in rescuing those displaced by climate events. By helping those displaced at the start of the climate migration process according to a more commonly held notion of the duty to rescue, and by preparing to incorporate newcomers successfully according to an expanded duty to rescue, effectively a duty to prepare, countries that take on climate refugees may find themselves rewarded by the cultural diversity and workplace talents that people bring. A duty to those at a distance is a reasonable expansion of the duty to rescue. But what one ought to do in the global community varies somewhat from the traditional Rule of Rescue. - [1] Singer, P.

We consider exponentially large finite relational structures (with the universe {0.1}ⁿ) whose basic relations are computed by polynomial size (nO(1)) circuits. We study behaviour of such structures when pulled back by P/poly maps to a bigger or to a smaller universe. In particular, we prove that: 1. If there exists a P/poly map g: {0.1} → {0.1}m, n < m, iterable for a proof system then a tautology (independent of g) expressing that a particular size n set is dominating in (...) a size 2ⁿ tournament is hard for the proof system. 2. The search problem WPHP, decoding RSA or finding a collision in a hashing function can be reduced to finding a size m homogeneous subgraph in a size 22m graph. Further we reduce the proof complexity of a concrete tautology (expressing a Ramsey property of a graph) in strong systems to the complexity of implicit proofs of implicit formulas in weak proof systems.

In this paper I will argue that the distinction between biological life and political life as found in Hannah Arendt’s reading of Aristotle and later repeated and elaborated by Giorgio Agamben under the headings of and, is in fact a fertile point of entry to, and the only viable option in order the grasp what constitutes the political as such for Aristotle. By hashing out the conceptual steps necessary for the establishment of what can be called a “political community”, I (...) seek to illuminate how the distinction upon which much of Arendt’s and Agamben’s works rests, does indeed play a vital role in the work of Aristotle. By clarifying the nature of a “political community” according to Aristotle, this paper thus seeks to make a proper assessment of the thought of both Arendt and Agamben possible. (shrink)

Faculty journals are one of the necessary platforms for qualified academic production. Since 2018, the number of the published journals of theology faculty has reached 56. The purpose of this study is to analyze the articles on religious education published at journals of theology faculty between 1925 and 2017 by virtue of the used research methods such as qualitative and quantitative, and numerical distribution according to the journals, subject area diversity, scientific research methods used, contributions of different science branches, number (...) of author and foreign language writing. Research is a type of descriptive and cross-sectional screening based on document analysis and content analysis. There are 604 articles on religious education published in journal of theology faculty. According to the results of the research, the religious education articles have a very wide subject network and the majority of the articles are the theoretical studies. Research is important in terms of revealing the current state of published works on religious education.SummaryReligious education is quite old as the practice, but as a scientific discipline is an area that can be considered new in Turkey. However, it should be noted that religious education has left behind a process that lasts nearly 40 years and has been making a rapid progress towards becoming a scientific discipline. In Turkey, the first journal of the Republican period in theology is The Journal of Dârü'l-Fünûn Faculty of Theology. it published 25 issues until 1933 in which the Dârü’l-fünûn Faculty of Theology ended its education. In this research, covering the 92-year period between 1925-2017, articles on religious education published in the journals of the faculty of theology have been evaluated by document analysis and content analysis. During the research, databases of all theology journals were examined through their web pages. There are 604 articles on religious education published in journals of theology faculty. There are only a limited number of studies in the literature that subject the articles in the field of religious education to assessment. The most relevant one to this research is the article by Kaymakcan and Ünsal about the religious education published in the journals of the theology faculty in 1952-2003. A total of 213 articles published in 18 journals of faculties were listed in alphabetical order.The purpose of this study is to analyze the religious education articles published at journals of theology faculty between 1925 and 2017 by virtue of the used research method such as qualitative and quantitative, and numerical distribution according to the journals, subject area diversity, scientific research methods used, contributions of different science branches, number of author and foreign language writing. Research is a type of descriptive and cross-sectional screening based on document analysis and content analysis. The scope of the research is limited to 57 faculties. All articles of all academicians working / had worked in main science branch of religious education were included in the research. In addition, articles of title of religious education / religious teaching which were written by academicians from other fields were also included in the study.The evaluation process of the published articles on religious education in the journals of theology faculty from 1925 to 2017 is divided into three parts. The first is the period from 1925 to 1980. In this period, a total of 17 articles have been published and each year an average of 0.3 percent of articles. The second part is between the years 1995 and 1995 when the new divinity magazines began to be published. In this process, 55 religious education articles were published in the journals of the faculty of theology. In this period, the average number of articles per year is 3,4. The third part is from 1996 to the present. In this period, a total of 532 articles were published and the average of articles per year was 24. One of the results of the study is that the articles on religious education published in the journals of the Faculty of Theology have a wide range of topics. When the subject classification of the articles is examined, it can be seen that the articles are divided into 10 main subject / problem areas. Foundations of religious Education history of religious education, formal religious education, common religious education, informal religious education, ethics and values education, education based on religion, development and religious education, religious education in the countries, person surveys are from these main subject areas. Formal religious education is the area where the most articles are produced (189 article). When we look into the faculty journals the most studies were published in the Journal of Faculty of Theology of Ankara University with 86 articles. With 59 articles Uludag, with 52 articles 19 May, with 51 articles The Republican Journal of Theology follow Ankara University Faculty of Theology Journal. 65% of the articles (368) were written based on the literature review method. 23% of the articles were quantitative, 10% were qualitative and 2% had mixed methods. The number of articles using the qualitative method is 54 and the number of articles using the hash method is 14. According to the academic studies of the authors, the distribution of articles related to religious education is given. According to this, religious education branch constitutes 85% of all articles with 510 articles. 15% of them are composed of 89 articles which are contributed by 23 branches such as theology, philosophy, sociology, literature, educational sciences, and social services. When we look at the distribution of the articles according to the academic study areas of their authors, it is revealed that the science of religious education has an interdisciplinary aspect. It seems that there is an article level contribution to the field of religious education from almost every discipline in theology. When we analyze the articles about religious education published in the faculty of theology journals in terms of the number of authors, it is seen that only 43 of the 604 articles were carried out by more than one researcher. Of the 43 articles with more than one author, 8 were theoretical and the other 35 used empirical methods. When we look at the publication of the articles published in the journals of Theology Faculty in foreign languages, only 12 articles were published in foreign languages. This ratio corresponds to 2%. 7 of the 12 articles were published in German, 4 in English and one in Arabic. According to the results of the study, the rate of writing in a foreign language on the religious education is clearly insufficient. These two problems not only belong to the field of religious education, but also to all the disciplines of theology. In particular, production of articles in foreign languages is obvious that pose a problem for all academic fields in Turkey. In this issue, individual and institutional developments are highly needed. (shrink)

Ruby and Perl are programming languages used in many fields. In this paper we would like to present their usefulness with regard to basic bioinformatic problems. We concentrate on a comparison of widely used Perl and relatively rarely used Ruby to show that Ruby can be a very efficient tool in bioinformatics. Both Perl and Ruby have a built-in regular expressions engine, which is essential in solving many problems in bioinformatics. We present some selected examples: printing the file content, removing (...) comments from a FASTA file, using hashes, printing nucleotides included in a sequence, searching for a specific nucleotide in sequence and translating nucleotide sequences into protein sequences obtained in GenBank format. It is our belief that Ruby’s popularity will rise because of its simple syntax and the richness of its methods. Programs in Ruby are very easy to read and therefore easier to maintain and debug, which are the most important characteristics for a programming language. (shrink)

Bitcoin is a virtual currency that provides a completely decentralized secure alternative to the currencies currently used. Nakamoto, the creator of this cryptocurrency, published an article on an encryption mailing list in 2008 with the title “Bitcoin: A Peer-to-Peer Electronic Cash System”, thus giving the creation of this virtual currency. This study aims to analyze the Bitcoin and what factors can influence its price, in the context of a pandemic. This work will focus on the bitcoin price and on five (...) different factors likely to have an influence on his price, such as: Hash Rate, Mining Difficulty, Volatility Index, Google Search and Transaction Cost. The period for this research ranges from 15/03/2020 to 14/11/2021, a total of 96 weeks, to integrate the covid-19 factor into the study. The results show that the variables fsCoinCirculation and fsTransationCost are both necessary conditions for an increase on the bitcoin price, but for low values of bitcoin price there are no necessary conditions. Additionally, findings suggest that Hash Rate influences the price of bitcoin. Finally, fsVix variable was found to be a variable with an important implication in price, namely, in its volatility.

This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...) drifiting thought that attention be paid to the contributions as they entered into conversation one after another. This particular piece is from the BETWEEN SPACE & PLACE thread: April Vannini, Those Between the Common * Laura Dean & Jesse McClelland, Ballard: A Portrait of Placemaking * Amara Hark Weber, Crossroad * Isaac Linder & Berit Soli-Holt, The Call of the Wild: Terro(i)r Modulations * Ashley D. Hairston, Momma taught us to keep a clean house * Sean Smith, The Garage (Take One) * * * * Preface: Variations of Archiving the Anarchive Through Editorial Witnessing by April Vannini “a diagram is a map, or rather several superimposed maps.” 1 What do we do with essays, art, artefacts, and practices that go against, resist, challenge and reject archival capture or documentation since they do not fit within the screen or manage to move beyond conventional scales? What do we do with an essay or artefact that is the event of the event becoming-event itself, or how do we move from volumetric space to two-dimensional space? How do editors, curators, participants, etc. become witness to an anarchive? And most importantly, what are the potential and unanticipated ways in which a volumetric submission can be diagrammed within a two- dimensional space? In short, how do we archive the anarchive? These are questions that have emerged and have been consciously and purposely activated by Sean Smith’s thinkpiece for this issue, The Garage (Take One) . Sean, as part of his contribution to the special issue of drift within the thread in between space and place , created an artefact that emerged out of an event held during May 2013, titled Cottage University: Topology and Immanence . The visual documentation of The Garage (Take One) is not an archive but an anarchive due to its multimodal form, non-representational diagramming, and its reactivation of non-representational folding which animates its non-representational or more-than -representational condition. In short, The Garage (Take One) stymies attempts to be translated into digital text, representationally. As a reader of Sean’s submission you will only have access to a portion of the original submitted contribution (see “Take One”). At this time, I remain the only witness of The Garage (Take One) in its entirety: I was present at the original event, Cottage University: Topology and Immanence , and I was the sole receiver of the original package because of my role as editor for the thread, in between space and place . However, I would like to stress that I was unaware of what Sean would submit as his contribution to the special issue. What is presented here is an emergent rippling of the event that was not predetermined or arranged in advance ... a drifting of sorts! As for now, the artefact sits here on my desk next to a pile of books—folded, creased and somewhat lost in its translation into digital form. Questions of transcribing, translating and converting volumetric space to two-dimensional space have been considered throughout this process. And more importantly this artefact and its processes raise the issue of not what has been saved and included but what has been left out in each conversion of the original into the academic publication. What follows this preface are various “cuts” or “takes” from The Garage: Take One . Each take or cut is merely an interpretive and representational rendering of the original volumetric submission. Although with that said I would like to propose they are more than just representations or interpretations: each take or cut works as rippling variations of the event itself . It is important to acknowledge that much has been lost in the creases and much still lingers which will never be archived within an academic journal. Hence, a discussion of how to archive the anarchive is so crucial to para-academic “scholarship”. I will sum up the process that has emerged from The Garage (Take One) with a final word from Brian Massumi, written in his foreword to Deleuze and Guattari’s A Thousand Plateaus : Each 'plateau' is an orchestration of crashing bricks extracted from a variety of disciplinary edifices. They carry traces of their former emplacement, which give them a spin defining the arc of their vector. The vectors are meant to converge at a volatile juncture, but one that is sustained, as an open equilibrium of moving parts each with its own trajectory. The word 'plateau' comes from an essay by Gregory Bateson on Balinese culture, in which he found a libidinal economy quite different from the West's orgasmic orientation. In Deleuze and Guattari, a plateau is reached when circumstances combine to bring an activity to a pitch of intensity that is not automatically dissipated in a climax. The heightening of energies is sustained long enough to leave a kind of afterimage of its dynamism that can be reactivated or injected into other activities, creating a fabric of intensive states between which any number of connecting routes could exist. 2 The Garage (Take One) Double Take 2:31pm/5:31pm Sean Smith You there? I just wanted to emphasize a couple of things about the process of the submission: 2:31pm/5:31pm April Warn-Vannini Yes, listening. 2:36pm/5:36pm Sean Smith 1.When you describe feeding forward from the CU (Cottage University) event, it is a WALKING ACTIVITY that reinvests/reactivates the intensive energies of the event. that is what my photos are in Take One......it connects the intensive state of CU to my "one-take" writing on construction paper experience. i'm not sure if i adequately conveyed that or not, or if you did, or how important that is. 2. In doing so, it ruptures open the "space" and "place" of material practice ...and how these may enter into the mediated production of academic journal work...and its flattened two-dimensional experience. 3. the abstract machines of CU (i.e.coming out of silence) are invested with a new diagramming practice (the photo walk) to produce a new text that is neither-nor: "spaced" as a content of that walk (garages), but "placed" as a technical question (coming out of silence to language). 4. the new text is precisely diagrammatic, non-representational, anarchival. ....multimodal. ok, that's all that comes to mind right now. appreciating your efforts. 5. oh, finally, i think you might need a better definition of "anarchive" here..... it was hard to pin them down in montreal on what this is, so you wouldn't be wrong, per se, but more require a working definition for the reader. obviously, as you say, without getting too academic/citations, etc. know what i am saying? 2:46pm/5:46pm April Warn-Vannini 1. Totally got it but I think I did because of our many past conversations about how to archive the event 2. Yes this is what I love about this. And I think you speak to this very carefully in your writing on the Garage. Now whether others pick up on this I don't know. This is why I wanted to see what it would look like if I flattened it (take 3). 5. I agree that a better definition is needed. This is where I've been stumbling because I have not found anything that clearly defines what is meant by anarchive. 2:47pm/5:47pm Sean Smith "with take one being the only remainder of the original submission left to reveal...." precisely because of its digitality!!! yeah, i would probably just append an edited version of what we are saying here, as if the editing process was still a ripple of the event. me "adding" new text later i think defeats the purpose, but if you were to take snippets of this dialogue as part of the anarachive/ 2:48pm/5:48pm April Warn-Vannini Totally! 2:49pm/5:49pm Sean Smith and just *use them*, i think that's fair game. that way i won't be crafting my words with intent. you can even use this profile pic. 2:50pm/5:50pm April Warn-Vannini Okay perfect. With that said, do you think I should just discuss your process further in the preface or include an introduction that would be in take one? 2:51pm/5:51pm Sean Smith could it be Take Two in its own right, like an atemporal ripple that coexists with the others and bumps them to Three, Four and Five? Or could it be called "Double Take" and leave the others as Two, Three, Four? 2:53pm/5:53pm April Warn-Vannini Perfect. I like double take 2:53pm/5:53pm Sean Smith and it's us hashing through this discussion 2:53pm/5:53pm April Warn-Vannini Double take will follow take one. i like this.

The key test cases for deciding between my brand of contextualism and Jennifer Nagel’s brand of invariantism are the third-person examples. As matters currently stand, first-person cases, like my original Bank cases (pp. 1-2), are pretty useless here. Nagel can agree that the speaker’s claim to “know” in Case A and his admission that he doesn’t “know” in Case B are both true; she just accepts a different account of why it is that both assertions can be, and are, true, (...) according to which it is because in B the speaker doesn’t meet the attitude requirement for knowledge, while he does meet that requirement in A. Perhaps not at all unexpectedly, I find my proposed explanation more plausible; presumably, Nagel sees things differently. We can try to hash this out, but extremely tricky questions, and no stable enough answers, about how to understand the attitude needed for knowledge derail this attempt to decide between accounts. But no worries: Without having to first decide these issues, third-person cases provide the natural test cases to decide between the views. We can use them to decide between theories, and then go back to the first-person cases and apply what we’ve learned from the third-person cases to guide our handling of the trickier firstperson cases.

Blockchain technology applied to cryptocurrencies is the dominant factor in maintaining the security of cryptocurrencies. This article reviews the technological implementation of cryptocurrency and the security and stability of cryptocurrency and analyzes the security support from blockchain technology and its platforms based on empirical case studies. Our results show that the security support from blockchain technology platforms is significantly insufficient and immature. In addition, we further Zyskind and Nathan and Choi and find that the top ten platforms play critical roles (...) in security support and have significant advantages in terms of funds, duration, and human resources. Moreover, these platforms provide computational resources and benefits to the consensus algorithm selection for blockchain practitioners. Second, encryption ensures the security of cryptocurrencies. On the one hand, the digital signatures identify the identity of the signatory and the transaction. However, the principle of the hash algorithm confirms ownership. Meanwhile, SHA256 is infeasible to compute in the reverse direction and is difficult to attack. Furthermore, the records in the blockchain can be queried by every participant, making the system information transparent and open reliable. Third, compared to the study of Fu and Fang 2016, we find that the blockchain structure is composed of security components and basic components of six layers that are independent and cannot be extended completely and have a certain coupling among them. Fourth, the underlying ledger structures of Bitcoin and DAG are highly correlated to their security. Specifically, we follow Sompolinsky et al. and detect that the structure of SPECTRE ensures network security and robustness from its block production, conflict resolution, and generated trusted transaction sets. Meanwhile, the voting algorithm of SPECTRE makes resolving conflicting transactions by calculating votes and ensuring the transaction information that is virtually unable to be tampered with possible. In particular, the security calculation power of SPECTRE can reach 51% and resist “double-spend attacks” and “censorship attacks” effectively. In addition, the RDL framework of SPECTRE achieves security confirmation of transferring funds. Moreover, PHANTOM identifies evil blocks by employing block connectivity analysis and ensures its security. Eventually, we also expand the studies of and compare the basic characteristics of the protocols of Bitcoin, SPECTRE, and PHANTOM and find that protocols play imperative roles throughout the implementation process of cryptocurrency. In addition, the underlying ledger structure and consensus mechanism make up a blockchain while the confirmation time, throughput limit, and ordering are prerequisites for smart contracts. (shrink)

In this paper I will argue that the distinction between biological life and political life as found in Hannah Arendt’s reading of Aristotle and later repeated and elaborated by Giorgio Agamben under the headings of (“bare life”) and (“qualified life”), is in fact a fertile point of entry to, and the only viable option in order the grasp what constitutes the political as such for Aristotle. By hashing out the conceptual steps necessary for the establishment of what can be called (...) a “political community”, I seek to illuminate how the distinction upon which much of Arendt’s and Agamben’s works rests, does indeed play a vital role in the work of Aristotle. By clarifying the nature of a “political community” according to Aristotle, this paper thus seeks to make a proper assessment of the thought of both Arendt and Agamben possible. (shrink)

Aiming at the problems of low recognition rate and slow recognition speed of traditional body action recognition methods, a human action recognition method based on data deduplication technology is proposed. Firstly, the data redundancy technology and perceptual hashing technology are combined to form an index, and the image is filtered from the structure, color, and texture features of human action image to achieve image redundancy processing. Then, the depth feature of processed image is extracted by depth motion map; finally, feature (...) recognition is carried out by convolution neural network so as to achieve the purpose of human action recognition. The simulation results show that the proposed method can obtain the optimal recognition results and has strong robustness. At the same time, it also fully proves the importance of human motion recognition. (shrink)

Parallel attribute reduction is one of the most important topics in current research on rough set theory. Although some parallel algorithms were well documented, most of them are still faced with some challenges for effectively dealing with the complex heterogeneous data including categorical and numerical attributes. Aiming at this problem, a novel attribute reduction algorithm based on neighborhood multigranulation rough sets was developed to process the massive heterogeneous data in the parallel way. The MapReduce-based parallelization method for attribute reduction was (...) proposed in the framework of neighborhood multigranulation rough sets. To improve the reduction efficiency, the hashing Map/Reduce functions were designed to speed up the positive region calculation. Thereafter, a quick parallel attribute reduction algorithm using MapReduce was developed. The effectiveness and superiority of this parallel algorithm were demonstrated by theoretical analysis and comparison experiments. (shrink)

BackgroundIncreasingly, hospitals and research institutes are developing technical solutions for sharing patient data in a privacy preserving manner. Two of these technical solutions are homomorphic encryption and distributed ledger technology. Homomorphic encryption allows computations to be performed on data without this data ever being decrypted. Therefore, homomorphic encryption represents a potential solution for conducting feasibility studies on cohorts of sensitive patient data stored in distributed locations. Distributed ledger technology provides a permanent record on all transfers and processing of patient data, (...) allowing data custodians to audit access. A significant portion of the current literature has examined how these technologies might comply with data protection and research ethics frameworks. In the Swiss context, these instruments include the Federal Act on Data Protection and the Human Research Act. There are also institutional frameworks that govern the processing of health related and genetic data at different universities and hospitals. Given Switzerland’s geographical proximity to European Union (EU) member states, the General Data Protection Regulation (GDPR) may impose additional obligations.MethodsTo conduct this assessment, we carried out a series of qualitative interviews with key stakeholders at Swiss hospitals and research institutions. These included legal and clinical data management staff, as well as clinical and research ethics experts. These interviews were carried out with two series of vignettes that focused on data discovery using homomorphic encryption and data erasure from a distributed ledger platform.ResultsFor our first set of vignettes, interviewees were prepared to allow data discovery requests if patients had provided general consent or ethics committee approval, depending on the types of data made available. Our interviewees highlighted the importance of protecting against the risk of reidentification given different types of data. For our second set, there was disagreement amongst interviewees on whether they would delete patient data locally, or delete data linked to a ledger with cryptographic hashes. Our interviewees were also willing to delete data locally or on the ledger, subject to local legislation.ConclusionOur findings can help guide the deployment of these technologies, as well as determine ethics and legal requirements for such technologies.

The use of wireless sensor networks and the Internet of things to detect forest fire outbreaks may help to reduce the response time and avoid natural disasters. This work proposes the deployment of WSN to enhance the real-time monitoring of dynamic variables such as polluting gases, temperature or the presence of fire flames by infrared. In addition, the activation of forest fire alerts if environmental status may involve evidence of a recent fire outbreak. A fuzzy-based controller is implemented to manage (...) the uncertainty related to estimating forest fire occurrence and dynamic update of fuzzy sets is developed to distinguish usual and unusual environmental conditions of every monitored forest area. Merkle trees, AES and hash functions are considered to protect the integrity of environmental data. (shrink)

Binding arbitration is generally less available in tort suits than in contract suits because most tort plaintiffs do not have a pre-dispute contract with the defendant, and are unlikely to consent to arbitration after the occurrence of an unforeseen injury. But the Federal Arbitration Act applies to all “contract[s] evincing a transaction involving commerce,” including contracts for healthcare and medical services. Given the broad trend towards arbitration in nearly every other business-to-consumer industry, coupled with some rollbacks in tort reform measures (...) that have traditionally favored medical professionals in the judicial system, it is very possible that we may witness in the near future more medical contracts containing arbitration provisions. As a consequence, all manner of tort claims might be hashed out in the sequestered universe of arbitration. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.3 (2000) 433-452 [Access article in PDF] When Ideas Matter: The Moral Philosophy of Fontenelle Gregory Matthew Adkins Introduction There has been a recent trend in the historiography of seventeenth- and eighteenth-century intellectual culture to analyze that culture from a sociological perspective. This perspective, a necessary corrective to a pure history of ideas, takes knowledge as a socially constructed phenomenon and thus subject (...) to sociological analysis. The point of the sociology of knowledge, however, is not to re-hash and bolster old externalist arguments but to do away with the whole debate over whether ideas or social conditions are more important in intellectual history and the history of science. A focus on sociology does not mean that ideas do not matter. This becomes apparent when analyzing the ethics of early modern intellectuals.For example, Anne Goldgar's recent work, Impolite Learning: Conduct and Community in the Republic of Letters, 1680-1750 (1995), gives much attention to the sociology of the seventeenth- and eighteenth-century Republic of Letters--but at the cost of relegating the role of ideas to the sidelines. According to Goldgar, if one wants to understand early modern intellectuals as a community, including their ethics and sense of morality, one should focus on forms of sociability rather than the ideas and philosophies they put forth in their writings. An aristocratic ethic dominated early modern scholarship, she argues, and even took precedence over knowledge claims: "[i]n striving to make its inner workings acceptable to the outside community the Republic of Letters chose, like the aristocracy, to empty its internal relationships of content, choosing instead to concentrate on form.... [A]rguments were often judged on the politeness with which they were presented, rather than on their intrinsic merit." 1 Men of [End Page 433] letters, although often of humble origin, cultivated nobility by emulating aristocratic modes of decorum and noble interests in status and reputation. One way they promoted these ideas was through a literary genre adopted from classical antiquity, the éloge (eulogy), which presented exemplary modes of behavior by praising the lives of the "heroes" of the Republic of Letters. Interestingly, the years on which Goldgar focuses her analysis almost precisely encompass the period of Bernard le Bouyer de Fontenelle's mature intellectual production. Yet Fontenelle (1657-1757), widely hailed during his lifetime as having perfected the art of the éloge, plays no role in her argument.From 1699 to 1740 Fontenelle, as secrétaire perpétuel of the Académie Royale des Sciences, composed some sixty-nine éloges in honor of recently deceased members of the academy and of other notable savants. Even a brief glance at Fontenelle's eulogies reveals an intimate link between philosophy and morality. A more careful examination of them in the context of his life and works shows that this link was logically commensurate with his genuinely held notions of human nature, happiness, reason, and the good. In fact the relationship in the eulogies between notions of nobility and the virtues proper to the savant or philosopher is highly intellectualized. Fontenelle was not as concerned with status and reputation or with self-fashioning as one might think. 2 We can only assimilate his ethics to those of the court aristocracy if we ignore what he actually wrote.Through his eulogies and other writings, Fontenelle's thoughts on philosophy and morality have had a lasting impact on western culture. He presented an image of what would come to characterize the proper, objective, modern scientist and thinker. 3 In order to understand the éloge as an institution in the Republic of Letters (and by extension the early modern intellectual ethic) it is therefore important to examine Fontenelle's moral philosophy more carefully. It is a philosophy expressed in his eulogies but understood clearly only in the context of his life and works. On the ÉlogesAs noted above, one way to contextualize the institution of the éloge is to place it within a Republic of Letters concerned with adopting the manners of the nobility: the éloges...
