The philosophy of Wittgenstein is both novel and enigmatic. What is his new revolutionizing methodology? What is his aim, his purpose, his intention? What does he mean by the puzzling terms ‘forms of life’, ‘language-games’, ‘seeing as’? The key to the answers, according to the thesis of this paper, lies in Wittgenstein’s conception of the ‘Weltanschauung’. By the explanation of the use of this term, the entire philosophy of Wittgenstein may become illuminated with new meaning and interpretation. In understanding the (...) meaning of the word ‘Weltanschauung’ we shall come to understand why Wittgenstein used his new method, just what that method was, and what the impact of the concept and method had on the terms ‘Language-game’, ‘forms of life’ and ‘seeing as’.

In [3], two different effective versions of Borel embedding are defined. The first, called computable embedding, is based on uniform enumeration reducibility, while the second, called Turing computable embedding, is based on uniform Turing reducibility. While [3] focused mainly on computable embeddings, the present paper considers Turing computable embeddings. Although the two notions are not equivalent, we can show that they behave alike on the mathematically interesting classes chosen for investigation in [3]. We give a “Pull-back Theorem”, saying that if (...) Φ is a Turing computable embedding of K into K’, then for any computable infinitary sentence φ in the language of K’, we can find a computable infinitary sentence φ* in the language of K such that for all.

Here we prove that if T and T′ are strongly minimal theories, where T′ satisfies a certain property related to triviality and T does not, and T′ is model complete, then there is no computable embedding of Mod(T) into Mod(T′). Using this, we answer a question from [4], showing that there is no computable embedding of VS into ZS, where VS is the class of infinite vector spaces over Q, and ZS is the class of models of Th(Z, S). Similarly, (...) we show that there is no computable embedding of ACF into ZS, where ACF is the class of algebraically closed fields of characteristic 0. (shrink)

The use of upper limb vibration during exercise and rehabilitation continues to gain popularity as a modality to improve function and performance. Currently, a lack of knowledge of the pathways being altered during ULV limits its effective implementation. Therefore, the aim of this study was to investigate whether indirect ULV modulates transmission along spinal and corticospinal pathways that control the human forearm. All measures were assessed under CONTROL and ULV conditions while participants maintained a small contraction of the right flexor (...) carpi radialis muscle. To assess spinal pathways, Hoffmann reflexes elicited by stimulation of the median nerve were recorded from FCR with motor response amplitudes matched between conditions. An H-reflex conditioning paradigm was also used to assess changes in presynaptic inhibition by stimulating the superficial radial nerve 37 ms prior to median nerve stimulation. Cutaneous reflexes in FCR elicited by stimulation of the SR nerve at the wrist were also recorded. To assess corticospinal pathways, motor evoked potentials elicited by transcranial magnetic stimulation of the contralateral motor cortex were recorded from the right FCR and biceps brachii. ULV significantly reduced H-reflex amplitude by 15.7% for both conditioned and unconditioned reflexes. Therefore, ULV inhibits cutaneous and H-reflex transmission without influencing corticospinal excitability of the forearm flexors suggesting increased presynaptic inhibition of afferent transmission as a likely mechanism. A general increase in inhibition of spinal pathways with ULV may have important implications for improving rehabilitation for individuals with spasticity. (shrink)

Good work in nursing is work that is scientifically effective as well as morally and socially responsible. The purpose of this study was to examine variables that sustain good work among entering nurses (with one to five years of experience) and experienced professional nurses despite the obstacles they encounter. In addition to role models and mentors, entering and experienced nurses identified team work, cohesiveness and shared values as levers for good work. These nurses used prioritization, team building and contemplative practices (...) to overcome obstacles. Entering professional nurses tended to avoid conflict in the work setting. Experienced nurses reported forming teams of decision makers who share similar values to resolve conflict. These findings have implications for nurse education and nursing practice. Reflection on the importance of values and virtue in sustaining good work is important. Entering professional nurses should be encouraged to seek positive role models and reflect on the lessons that can be learned from experienced exemplary nurses. (shrink)

Many research ethics guidelines now oblige researchers to offer research participants the results of research in which they participated. This practice is intended to uphold respect for persons and ensure that participants are not treated as mere means to an end. Yet some scholars have begun to question a generalised duty to disclose research results, highlighting the potential harms arising from disclosure and questioning the ethical justification for a duty to disclose, especially with respect to individual results. In support of (...) this view, we argue that current rationales for a duty of disclosure do not form an adequate basis for an ethical imperative. We review policy guidance and scholarly commentary regarding the duty to communicate the results of biomedical, epidemiological and genetic research to research participants and show that there is wide variation in opinion regarding what should be disclosed and under what circumstance. Moreover, we argue that there is fundamental confusion about the notion of “research results,” specifically regarding three core concepts: the distinction between aggregate and individual results, amongst different types of research, and across different degrees of result veracity. Even where policy guidance and scholarly commentary have been most forceful in support of an ethical imperative to disclose research results, ambiguity regarding what is to be disclosed confounds ethical action.

In this essay we argue that the current social and ethical structure in the Open Source Software Community stem from its roots in academia. The individual developers experience a level of autonomy similar to that of a faculty member. Furthermore, we assert that the Open Source Software Community’s social structure demands benevolent leadership. We argue that it is difficult to pass off low quality open source software as high quality software and that the Open Source development model offers strong accountability. (...) Finally, we argue that Open Source Software introduces ethical challenges for universities and the software development community. (shrink)

Data monitoring committees often are employed to review interim findings of randomised controlled trials. Interim findings are kept confidential until the data monitoring committee finds that they provide sufficiently compelling evidence regarding efficacy, typically because they have crossed the pre-defined statistical boundaries, or they raise serious concerns about safety. While this practice is vital to maintaining the scientific integrity of controlled trials and thereby ensuring their social value, it has been criticised as unethical. Commentators argue that withholding interim findings from (...) research participants is deceptive, inconsistent with valid informed consent, and a violation of respect for participants’ autonomy. The present article examines these arguments, focusing specifically on confidential data monitoring for efficacy. This practice need not be deceptive provided its use is disclosed to prospective research participants. In addition, confidential data monitoring does not make research participants worse off than they would be in the clinical setting and represents an acceptable limitation on the options available to prospective research participants. Taken together, these considerations suggest confidential data monitoring, subject to adequate safeguards, is ethically acceptable. (shrink)

Emile Benvcniste may be used to introduce the topic. The French linguist begins an essay on “Euphemisms Ancient and Modern” with a paradox about the early Greek definitions of euphemism. “To speak words which augur well” is one meaning given, but another is “to maintain silence”. This initial contradiction is further compounded by yet a third expression, “to shout in triumph”. The dilemma is. however, easily dissolved. To speak words which augur well implies, for special occasions, an exhortation even to (...) shout triumphantly, “to assent by an, auspicious outcry”: it further implies, again depending on the circumstances, “to avoid words which augur ill”, hence, if necessary, to say nothing. As one definition explains “avoid all unlucky words during sacred rites: hence, as the surest mode of avoiding them, keep a religious silence” (original emphasis). Paradox terminates; we are merely dealing with “a euphemism for a euphemism” taking an expression of Benveniste out of context. (shrink)

"The Rules" are found in a collaborative document that states principles for responsibility when a computer artifact is designed, developed and deployed into a sociotechnical system. At this writing, over 50 people from nine countries have signed onto The Rules. Unlike codes of ethics, The Rules are not tied to any organization, and computer users as well as computing professionals are invited to sign onto The Rules. The emphasis in The Rules is that both users and professionals have responsibilities in (...) the production and use of computing artifacts. In this paper, we use The Rules to examine issues of trust. (shrink)

We contend that software developers have an ethical responsibility to strive for reliable software. We base that obligation on long standing engineering traditions that place the public good as a central tenant and on the professional relationship between a software developer and the users of the software developed.

Participants are often not informed by investigators who conduct randomised, placebo-controlled acupuncture trials that they may receive a sham acupuncture intervention. Instead, they are told that one or more forms of acupuncture are being compared in the study. This deceptive disclosure practice lacks a compelling methodological rationale and violates the ethical requirement to obtain informed consent. Participants in placebo-controlled acupuncture trials should be provided an accurate disclosure regarding the use of sham acupuncture, consistent with the practice of placebo-controlled drug trials.

The hippocampal formation is a structure critical to navigation and many forms of memory. In mammals, the firing of place cells is widely regarded as the fundamental unit of HF information processing. Supporting homology between the avian and mammalian HF, context-specific patterns of Egr1 have been reported in birds that are comparable to those produced by place cell firing in mammals. Recent electrophysiological data, however, suggest that many avian species lack place cells, potentially undermining the correspondence between Egr1 and place (...) cell-related firing in the avian brain. To clarify this, the current study examines Egr1 expression in Japanese quail under conditions known to elicit only weakly spatially modulated firing patterns and report robust context-dependent Egr1 expression. These data confirm that context-dependent expression of Egr1 is not dependent on precise place fields and provide insight into how these birds are able to perform complex spatial tasks despite lacking mammalian-like place cells.

There is a growing literature on the concept of e-trust and on the feasibility and advisability of “trusting” artificial agents. In this paper we present an object-oriented model for thinking about trust in both face-to-face and digitally mediated environments. We review important recent contributions to this literature regarding e-trust in conjunction with presenting our model. We identify three important types of trust interactions and examine trust from the perspective of a software developer. Too often, the primary focus of research in (...) this area has been on the artificial agents and the humans they may encounter after they are deployed. We contend that the humans who design, implement, and deploy the artificial agents are crucial to any discussion of e-trust and to understanding the distinctions among the concepts of trust, e-trust and face-to-face trust.

Payment for research participation has raised ethical concerns, especially with respect to its potential for coercion. We argue that characterising payment for research participation as coercive is misguided, because offers of benefit cannot constitute coercion. In this article we analyse the concept of coercion, refute mistaken conceptions of coercion and explain why the offer of payment for research participation is never coercive but in some cases may produce undue inducement.

Although established in the law and current practice, the determination of death according to neurological criteria continues to be controversial. Some scholars have advocated return to the traditional circulatory and respiratory criteria for determining death because individuals diagnosed as ‘brain dead’ display an extensive range of integrated biological functioning with the aid of mechanical ventilation. Others have attempted to refute this stance by appealing to the analogy between decapitation and brain death. Since a decapitated animal is obviously dead, and ‘brain (...) death’ represents physiological decapitation, brain dead individuals must be dead. In this article we refute this ‘decapitation gambit.’ We argue that decapitated animals are not necessarily dead, and that, moreover, the analogy between decapitation and the clinical syndrome of brain death is flawed.

The purpose of this study was to determine whether accounting students’ perception of moral intensity could be enhanced through a limited ethics intervention in an Advanced Accounting course. Ethical decisions are heavily influenced by the intensity of the moral problem: the more egregious the act, the more the people view it as unethical. This controlled experiment measures the change in perceptions of moral intensity with the pre- and post-test instruments using five accounting specific vignettes containing moral dilemmas which are progressively (...) more intense. While other studies have shown that perceived moral intensity directly influences a persons’ moral decision-making process, as far as we are aware, this is the first study that assesses and tests whether the coverage of specific ethics content integrated into an accounting class can positively influence the students’ perception of moral intensity, moral sensitivity/awareness, moral judgment, and moral intentions. Positively influencing students’ moral sensitivity/awareness, moral judgment, and moral intentions is a critical first step to ensuring that our courses and curricula provide the learning environment in which students can develop knowledge and competencies required to become the ethical leaders of tomorrow.

Ethical guidelines for conducting clinical trials have historically been based on a perceived therapeutic obligation to treat and benefit the patient-participants. The origins of this ethical framework can be traced to the Hippocratic oath originally written to guide doctors in caring for their patients, where the overriding moral obligation of doctors is strictly to do what is best for the individual patient, irrespective of other social considerations. In contrast, although medicine focuses on the health of the person, public health is (...) concerned with the health of the entire population, and thus, public health ethics is founded on the societal responsibility to protect and promote the health of the population as a whole. From a public health perspective, research ethics should be guided by giving due consideration to the risks and benefits to society in addition to the individual research participants. On the basis of a duty to protect the population as a whole, a fiduciary obligation to realise the social value of the research and the moral responsibility to distribute the benefits and burdens of research fairly across society, how a public health perspective on research ethics results in fundamental re-assessments of the proper course of action for two salient topical issues in research ethics is shown: stopping trials early for reasons of efficacy and the conduct of research on less expensive yet less effective interventions.

Dual-track assessment directs research ethics committees to assess the risks of research interventions based on the unclear distinction between therapeutic and non-therapeutic interventions. The net risks test, in contrast, relies on the clinically familiar method of assessing the risks and benefits of interventions in comparison to the available alternatives and also focuses attention of the RECs on the central challenge of protecting research participants.Research guidelines around the world recognise that clinical research is ethical only when the risks to participants are (...) reasonable.1 Appropriate implementation of this requirement is vital to protecting research participants and allowing research to proceed when it poses acceptable risks. Unfortunately, as the US National Bioethics Advisory Commission notes: “current regulations do not further elaborate how risks and potential benefits are to be assessed, and little additional guidance is available to IRBs.”1The NBAC, as well as numerous commentators, recommend that research ethics committees , ethics review committees and institutional review boards should adopt what may be called dual-track risk assessment.2–5 Yet, dual-track assessment unnecessarily divides research interventions into two different categories before assessing their risks and relies on the unclear distinction between therapeutic and non-therapeutic interventions. As a result, dual-track assessment provides RECs with confusing guidance and has the potential to block valuable research that poses acceptable risks. This paper describes one alternative, the net risks test, and argues that this approach offers a better method for assessing research risks, one that puts RECs in a position to protect participants without blocking appropriate research studies.BACKGROUNDClinical research exposes participants to interventions and procedures to gather systematic data that may be used to improve overall health and well-being. To ensure that research is ethical, RECs must ensure that the risks and burdens to participants are not excessive and that …. (shrink)

A growing body of literature places blame for accounting frauds on the failure of educators to implement ethics training in accounting curriculums in higher educational institutions. Although, the professional accountancy bodies in the UK espouse high ethical standards, others suggest that these bodies are failing to cover ethics in any meaningful way. This study surveys faculty about what is being taught and how much time is dedicated to ethics training. This is the first study to examine whether content suggested by (...) the Ethics Education Framework has been implemented in curriculums in the UK. In addition, we look to determine if there is a notable difference between what is covered in both pre-1992 and post-1992 UK universities. Although we find that post-1992 institutions have implemented the EEF suggestions more than pre-1992 UK universities, current ethics training is insufficient and has not changed much over the last two decades.

Transplantation of vital organs has been premised ethically and legally on "the dead donor rule" (DDR)—the requirement that donors are determined to be dead before these organs are procured. Nevertheless, scholars have argued cogently that donors of vital organs, including those diagnosed as "brain dead" and those declared dead according to cardiopulmonary criteria, are not in fact dead at the time that vital organs are being procured. In this article, we challenge the normative rationale for the DDR by rejecting the (...) underlying premise that it is necessarily wrong for physicians to cause the death of patients and the claim that abandoning this rule would exploit vulnerable patients. We contend that it is ethical to procure vital organs from living patients sustained on life support prior to treatment withdrawal, provided that there is valid consent for both withdrawing treatment and organ donation. However, the conservatism of medical ethics and practical concerns make it doubtful that the DDR will be abandoned in the near future. This leaves the current practice of organ transplantation based on the "moral fiction" that donors are dead when vital organs are procured. (shrink)

Fraïssé studied countable structures S through analysis of the age of S i.e., the set of all finitely generated substructures of S. We investigate the effectiveness of his analysis, considering effectively presented lists of finitely generated structures and asking when such a list is the age of a computable structure. We focus particularly on the Fraïssé limit. We also show that degree spectra of relations on a sufficiently nice Fraïssé limit are always upward closed unless the relation is definable by (...) a quantifier-free formula. We give some sufficient or necessary conditions for a Fraïssé limit to be spectrally universal. As an application, we prove that the computable atomless Boolean algebra is spectrally universal.

We study the relative computational power of structures related to the ordered field of reals, specifically using the notion of generic Muchnik reducibility. We show that any expansion of the reals by a continuous function has no more computing power than the reals, answering a question of Igusa, Knight, and Schweber [7]. On the other hand, we show that there is a certain Borel expansion of the reals that is strictly more powerful than the reals and such that any Borel (...) quotient of the reals reduces to it.
