This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It is concluded (...) that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination‐shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus‐response relationships, not with the acquisition of mediating rules such as conceived in (neo‐)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures. (shrink)

This book evaluates the major debates around which the discipline of international relations has developed in the light of contemporary feminist theories. The three debates (realist versus idealist, scientific versus traditional, modernist versus postmodernist) have been subject to feminist theorising since the earliest days of known feminist activities, with the current emphasis on feminist, empiricist standpoint and postmodernist ways of knowing. Christine Sylvester shows how feminist theorising could have affected our understanding of international relations had it been included in (...) the three debates. She elaborates a feminist method of empathetically cooperative conversation which challenges the identity politics of IR, and illustrates that method with reference to the Greenham Common Women's Peace Camp and the efforts of Zimbabwean women to negotiate international funding for their local producer cooperatives.

BackgroundThe Western-European concept of libertarian rights-based autonomy, which advocates respect for individual rights, may conflict with African cultural values and norms. African communitarian ethics focuses on the interests of the collective whole or community, rather than rugged individualism. Hence collective decision-making processes take precedence over individual autonomy or consent. This apparent conflict may impact informed consent practice during biomedical research in African communities and may hinder ethical principlism in African bioethics. This study explored African biomedical researchers' perspectives regarding informed consent (...) and potential limitations to the principle of respect for autonomy in African communities.MethodsWe conducted a qualitative study based on in-depth interviews with 12 biomedical researchers, five females and seven males aged 34 to 74 years, currently working at an African university. Interviews lasted 35–40 min each and involved semi-structured open-ended interviews, which allowed participants to offer information about their perceptions and feelings regarding respect for autonomy and informed consent as practised in Africa. Empirical data from the interviews were recorded, transcribed, and analysed using thematic content analysis, together with an interrogation of relevant scientific literature about African communitarian ethics, making evaluations and drawing inferences consistent with the empirical bioethics approach.ResultsBased on these interviews and analysis of relevant literature, we found that informed consent is difficult to apply in an African context because it derives from a Western conception of libertarian rights-based autonomy. Most respondents pointed out that it was challenging to implement informed consent in the African setting. Furthermore, communalism, customary beliefs, spirituality, and relational autonomy are predominant in most African communities, as exemplified by the African moral philosophies of Ubuntu/botho and Ukama, which emphasize communitarianism over individual rights. We also found that language, education, poverty, and cultural beliefs are barriers to obtaining proper informed consent in African communities.ConclusionsWe conclude that there are limitations to applying the principle of respect for autonomy and informed consent in African communities, especially in the context of human biomedical research. We recommend using a more relational approach, such as Ross’s prima facie duties, to implement informed consent in African communities. (shrink)

BackgroundThe issue of stigma is very important in the battle against HIV/aids in Africa since it may affect patient attendance at healthcare centres for obtaining antiretroviral medications and regular medical check-ups. Stigmatization creates an unnecessary culture of secrecy and silence based on ignorance and fear of victimization. This study was designed to determine if there is external stigmatization of people living with HIV and AIDS by health care workers at a tertiary hospital in KwaZulu-Natal province, South Africa. The study investigated (...) the impact of knowledge of HIV/aids by HCWs on treatment of patients, as well as the comfort level and attitude of HCWs when rendering care to PLWHA.MethodsA descriptive cross sectional study was designed to collect data using an anonymous self-administered structured questionnaire from 334 HCWs. The study was conducted in clinical departments of a large multidisciplinary 922-bed tertiary care teaching hospital in Durban, KZN.ResultsOverall HCWs had an above average knowledge about HIV/aids although some gaps in knowledge were identified. Tests of statistical significance showed that there was association between level of education and knowledge of HIV/aids ; occupation and knowledge of HIV/aids ; and gender and knowledge of HIV/aids. Test for comfort level was only significant for gender, with males showing more comfort and empathy when dealing with PLWHA. The study also revealed that patients were sometimes tested for HIV without informed consent before surgery, due to fear of being infected, and there was some gossiping about patients' HIV status by HCWs, thereby compromising patient confidentiality. The majority of HCWs showed a willingness to report incidents of stigmatization and discrimination to higher authorities, for better monitoring and control.ConclusionsAlthough knowledge, attitude and comfort level of HCWs taking care of PLWHA was above average, enforcement of existing antidiscrimination laws and continuing education in medical ethics and healthcare law, would greatly improve the performance of HCWs taking care of PLWHAs. More psychological support and counselling should be provided to HCWs, to further reduce the impact of stigmatization and discrimination against PLWHA. (shrink)

The 3rd Pan-African Ethics Human Rights and Medical Law (3rd EHRML) conference was held in Johannesburg on July 7, 2013, as part of the Africa Health Congress. The conference brought together bioethicists, researchers and scholars from South Africa, Zimbabwe, Kenya and Nigeria working in the field of bioethics as well as students and healthcare workers interested in learning about ethical issues confronting the African continent. The conference which ran with a theme of "Bioethical and legal perspectives in biomedical research and (...) medical practice in Africa with a focus on: Informed consent, HIV-AIDS & Tuberculosis, leadership & organizational ethics, patients and healthcare workers rights," was designed to expand the dialogue on African bioethics beyond the traditional focus on research ethics and the ethical dilemmas surrounding the conduct of biomedical research in developing countries. This introductory article highlights some of areas of focus at the conference including issues of leadership, organizational ethics and patients and healthcare workers rights in Africa. We analyze the importance of free speech, public debate of issues, argumentation and the need to introduce the teaching and learning of ethics to students in Africa in accordance with UNESCO guidelines. This article also focuses on other challenges confronting Africa today from an ethical standpoint, including the issues of poor leadership and organizational ethics which are main contributors to the problems prevalent in African countries, such as poverty, poor education and healthcare delivery systems, terrorism, social inequities, infrastructural deficits and other forms of 'structural violence' confronting vulnerable African communities. We believe that each of the eight articles included in this supplement, which have been rigorously peer-reviewed are a good example of current research on bioethics in Africa, and explore some new directions towards broadening the African bioethics agenda as we move forward to a new dawn for Africa in the 21st century.

Publication date: 14 June 2017 Source: Author: Sylvester Tabe Arrey This work examines events from Cameroon's life since becoming a nation to foster understanding of the worrisome political situation the country has been traversing since 2016. Bitter and unhappy with their treatment since joining the French-speaking part, many citizens of the minority English-speaking part feel fed up and desire a breakup. I show that apart from constituting an aspect of its pride, Cameroon's history is also a source of tricky (...) challenges the country has been wrestling with since inception. I contend that issues of this kind will always be around if those in the country's cockpit fly it to a destination other than what satisfies and respects the two people – especially the one that moved the English-speaking part to opt for a joint destiny. Instead of toying with truth to score personal political points, authorities should yield to truth, operating in good faith to correct errors and heal hurt hearts so that both people will willingly, not by force, accept to work together. Contrary actions will risk the future. Happiness moves people to look at their history with pride finding things to build while pain stirs frustration and fury, moving them to search for flaws to fix or fight. I hold that both parts face almost the same challenges from unmet needs to emaciating struggles of survival. However, the English-speaking part has unique plaques that ache terribly and have nothing to do with the country’s general cry of lagging development. They touch on its identity and survival, unleashing pain many out of its shoes might fail to feel and so unable to understand the degree of excruciation. I caution that though it has been a show of two regions, the likelihood of someday evolving into a ten-region revolution is certain if wise and inclusive actions are not applied. Apart from groaning in their own pain, many among the other eight are sympathetic to the predicament of the lamenting two, expressing fury, first, against the denial by highly placed authorities of the existence of any problem, and second, in their ruthless and brutal treatment of those who complain or challenge their stance. Anger increased as people's patience waned. Their calm will not last if things stay unchanged. When arguments evolve and accommodate their worries they will get on board pushing the heat to levels officials will have problems containing without facing the temptation of fighting the people they are in office to protect. I end with recommendations the state and activists might find useful. They highlight measures that can help in a heterogeneous society like Cameroon to preserve peace and save it from becoming a scene of mayhem and butchery. (shrink)

Abstrak: Etika keduniawian Hannah Arendt muncul dari cara khasnya memikirkan dunia dan tindakan-tindakan manusia di dalamnya. Bagi Arendt, lewat berpikir, manusia mengungkapkan opini dan perhatiannya pada dunianya, apa yang terjadi di dunia. Lewat berpikir, manusia menunjukkan sebentuk tanggung jawabnya terhadap dunia dimana ia terlempar. Dengan menilai sebuah tindakan politik, manusia disetir oleh nilai-nilai moral yang berasal dari dunia itu sendiri. Penilaian yang ia berikan, pada gilirannya ada di bawah putusan orang-orang lain yang mengkonfrontasinya. Artinya, saat kita berpikir dan menilai, kita (...) mesti sadar akan makna tindakan politis bagi dunia pada umumnya, dan kita juga mesti menyadari apa yang akan dikatakan orang lain tentangnya. Kata-kata Kunci: Etika, keduniawian, berpikir, menilai, tanggungjawab. Abstract: This paper aims at reconstructing Arendt’s ethics of worldliness from her specific way of thinking about the world and how to judge an action takes place in it. For Arendt, in thinking, we express our concern and opinion about the world and what is going on in it. It is one way of showing our responsibility for the world into which we are thrown. In judging a political action we are directed by ethical constraints to come from the world itself and the verdict of spectators. That means, when we judge we should be aware of the things that an action could bring to the public realm and what others might say about it. Keywords: Ethics, worldliness, thinking, judging, responsibility. (shrink)

Epistemic interactivism, an aspect of the epistemology of representation, is a cognitive intercourse between the subject and person-object of knowledge that underlies the conception of a person in Esan thought. Traditional theories of representation (especially as presented by Descartes and Locke) separated the subject from the object of knowledge, and classified persons and non-persons as object of knowledge. This separation and classification ignored the cognitive and moral values of persons, disengaged the subject from the world and burden the self with (...) solitude and isolation, and created propositional knowledge that dehumanised the relationship between the subject and person-object of knowledge. Within the theoretical framework of Hegel's epistemic interactivism (meliorated by Bowne's personalism) and Esan epistemology (in African philosophy), this book exposes the epistemic interactivism of Esan thought which unified the subject and person-object of knowledge on cognitive and moral grounds; thus providing adequate basis for personhood and resolving the dehumanised relationship between the subject and person-object of knowledge in the traditional theories of representation. Within the context of epistemic injustices, this book analyses the interactivist epistemology of indigenous Esan thought as an alternative epistemological conception of the person-object of knowledge which resolves the deficiency of the traditional theories of representation.

The Covid-19 pandemic has compounded the global food insecurity crisis, disproportionately affecting the consumers, farmers, and food workers. The significant disruptions caused by Covid-19 have called international attention to food security and sparked conversations about how to better support food production and trade. Our paper contributes to a small but growing literature on the impacts and responses of agroecological farmers to Covid-19 in Costa Rica. Specifically, we interviewed 30 agroecological farmers about livelihood disruptions during Covid-19, the areas of food production (...) and sales most affected during this pandemic, and how farmers and consumers are adapting during this crisis. Our findings reveal multiple impacts on agroecological farmers including: economic hardships of lower incomes and inability to pay loans, changes in purchasing and consumption patterns, market disruptions, changes in sales, a decrease in agrotourism, and a shortage of farmworkers. Furthermore, we also report the following farmer adaptation strategies: minimizing distance with consumers to facilitate direct delivery, establishing e-commerce platforms. Based on our findings, we recommend the following: building farmer networks for knowledge sharing, increasing technological support for farmers, and providing government support to ensure that such crises do not increase unemployment among farmers and exacerbate food insecurity.

Recent Darwin scholarship has provided grounds for recognising the Origin as a literary as well as a scientific achievement. While Darwin was an acute observer, a gifted experimentalist and indefatigable theorist, this essay argues that it was also crucial to his impact that the Origin transcended the putative divide between the scientific and the literary. Analysis of Darwin’s development as a writer between his journal-keeping on HMS Beagle and his construction of the Origin argues the latter draws on the pattern (...) of the Romantic or Kantian sublime. The Origin repeatedly uses strategies which challenge the natural-theological appeal to the imagination in conceiving nature. Darwin’s sublime coaches the Origin’s readers into a position from which to envision nature that reduces and contains its otherwise overwhelming complexity. As such, it was Darwin’s literary achievement that enabled him to fashion a new ‘habit of looking at things in a given way’ that is the centrepiece of the scientific revolution bearing his name.

Like all technologies, nanotechnology will inevitably present risks, whether they result from unintentional effects of otherwise beneficial applications, or from the malevolent misuse of technology. Increasingly, risks from new and emerging technologies are being regulated at the international level, although governments and private experts are only beginning to consider the appropriate international responses to nanotechnology. In this paper, we explore both the potential risks posed by nanotechnology and potential regulatory frameworks that law may impose. In so doing, we also explore (...) the various rationales for international regulation including the potential for cross-boundary harms, sharing of regulatory expertise and resources, controlling protectionism and trade conflicts, avoiding a “race to the bottom” in which governments seek economic advantage through lax regulation, and limiting the “nano divide” between North and South. Finally, we examine some models for international regulation and offer tentative thoughts on the prospects for each. (shrink)

Risk management of nanotechnology is challenged by the enormous uncertainties about the risks, benefits, properties, and future direction of nanotechnology applications. Because of these uncertainties, traditional risk management principles such as acceptable risk, cost–benefit analysis, and feasibility are unworkable, as is the newest risk management principle, the precautionary principle. Yet, simply waiting for these uncertainties to be resolved before undertaking risk management efforts would not be prudent, in part because of the growing public concerns about nanotechnology driven by risk perception (...) heuristics such as affect and availability. A more reflexive, incremental, and cooperative risk management approach is required, which not only will help manage emerging risks from nanotechnology applications, but will also create a new risk management model for managing future emerging technologies.

There is much we do not know about nanotechnology. Despite its tremendous promise, nanotechnology today is mostly forecast and fervent hope. Predictions that spending on nanotechnology will increase from current levels of $13 billion to more than $1 trillion by 2015 are no more than that – simply predictions. Hopes that nanotechnology will be an essential part of solving the globe's energy, food, and water problems should be tempered by recalling a century of revolutionary technologies that failed to live up (...) to their early promise such as nuclear energy, supersonic airplanes, or gene therapy. Many other questions continue to nip at nanotechnology's heels, not the least of which are debates about what is and is not technically feasible. Despite these uncertainties, we can have complete confidence in one aspect of nanotechnology's future – it will be subject to a host of regulations. (shrink)

As policy makers struggle to develop regulatory oversight models for nanotechnologies, there are important lessons that can be drawn from previous attempts to govern other emerging technologies. Five such lessons are the following: public confidence and trust in a technology and its regulatory oversight is probably the most important factor for the commercial success of a technology; regulation should avoid discriminating against particular technologies unless there is a scientifically based rationale for the disparate treatment; regulatory systems need to be flexible (...) and adaptive to rapidly changing technologies; ethical and social concerns of the public about emerging technologies need to be expressly acknowledged and addressed in regulatory oversight; and international harmonization of regulation may be beneficial in a rapidly globalizing world.

This paper critically assesses existing accounts of the nature of difficulty, finds them wanting, and proposes a new account. The concept of difficulty is routinely invoked in debates regarding degrees of moral responsibility, and the value of achievement. Until recently, however, there has not been any sustained attempt to provide an account of the nature of difficulty itself. This has changed with Gwen Bradford’s Achievement, which argues that difficulty is a matter of how much intense effort is expended. But while (...) this account captures something important about the relationship between difficulty and achievement, it fails to account for the fact that part of what makes achievements great is that they are difficult in a moderately agent-neutral kind of way. Nor is this thought captured by any other extant account. I argue that to fill this gap we should think of difficulty in terms of low probability of success. (shrink)

Responsible Research and Innovation (RRI) reflects an innovation paradigm that acknowledges that market innovations do not automatically deliver on socially desirable objectives, and requires a broad governance of knowledge coalitions of governmental bodies as well as industrial and societal actors to address market deficits. Responsible Innovation should be understood as a new paradigm for innovation which requires institutional changes in the research and innovation system and the public governance of the economy. It also requires the institutionalisation of an ethics of (...) co-responsibility as well as the introduction of new standards and certification processes for products. Dr. Dr. phil. von Schomberg will introduce Responsible Innovation against the background of 6 deficits of the (global) research and innovation system. (shrink)

The present work is substantially the same as the content of the second series of lectures, then advertised under the not very adequate title 'Values'. It is my plan to publish a revised version of the content of the first series of lectures, called 'Norms', as a separate book. (...) The two works will be independent of one another. (shrink)

Nanotechnology is the latest in a growing list of emerging technologies that includes nuclear technologies, genetics, reproductive biology, biotechnology, information technology, robotics, communication technologies, surveillance technologies, synthetic biology, and neuroscience. As was the case for many of the technologies that came before, a key question facing nanotechnology is what type of regulatory oversight is appropriate for this emerging technology. As two of us wrote several years ago, the question facing nanotechnology is not whether it will be regulated, but when and (...) how.Yet, appropriate regulation of nanotechnology will be challenging. The term “nanotechnology” incorporates a broad, diverse range of materials, technologies, and products, with an even greater spectrum of potential risks and benefits. This technology slashes across the jurisdiction of many existing regulatory statutes and regulatory agencies, and does so across the globe. Nanotechnology is developing at an enormously rapid rate, perhaps surpassing the capability of any potential regulatory framework to keep pace. Finally, the risks of nanotechnology remain largely unknown, both because of the multitude of variations in the technology and because of the limited applicability of traditional toxicological approaches such as structure-activity relationship to nanotechnology products.

way on the information available in the contexts in which they are used, it’s not surprising that there is a minor but growing industry of work in semantics and the philosophy of language concerned with the precise nature of the context-dependency of epistemically modalized sentences.
