Background: The search for genetic variants between racial/ethnic groups to explain differential disease susceptibility and drug response has provoked sharp criticisms, challenging the appropriateness of using race/ethnicity as a variable in genetics research, because such categories are social constructs and not biological classifications.Objectives: To gain insight into how a group of genetic scientists conceptualise and use racial/ethnic variables in their work and their strategies for managing the ethical issues and consequences of this practice.Methods: In-depth semi-structured interviews were conducted with a (...) purposive sample of 30 genetic researchers who use racial/ethnic variables in their research. Standard qualitative methods of content analysis were used.Results: Most of the genetic researchers viewed racial/ethnic variables as arbitrary and very poorly defined, and in turn as scientifically inadequate. However, most defended their use, describing them as useful proxy variables on a road to “imminent medical progress”. None had developed overt strategies for addressing these inadequacies, with many instead asserting that science will inevitably correct itself and saying that meanwhile researchers should “be careful” in the language chosen for reporting findings.Conclusions: While the legitimacy and consequences of using racial/ethnic variables in genetics research has been widely criticised, ethical oversight is left to genetic researchers themselves. Given the general vagueness and imprecision we found amongst these researchers regarding their use of these variables, they do not seem well equipped for such an undertaking. It would seem imperative that research ethicist move forward to develop specific policies and practices to assure the scientific integrity of genetic research on biological differences between population groups.

Humanitarian health care practitioners working outside familiar settings, and without familiar supports, encounter ethical challenges both familiar and distinct. The ethical guidance they rely upon ought to reflect this. Using data from empirical studies, we explore the strengths and weaknesses of two ethical models that could serve as resources for understanding ethical challenges in humanitarian health care: clinical ethics and public health ethics. The qualitative interviews demonstrate the degree to which traditional teaching and values of clinical health ethics seem insufficient (...) for addressing all the realities of health care practice during humanitarian missions. They equally suggest that greater good orientations of public health ethics can thwart the best intentions of health care professionals wanting to attend to the interests of individual patients. Even though neither is complete on its own for helping guide health professionals on field missions, taken together these models have much to offer. At the same time, the narratives of the humanitarian health care workers illustrate how some of the crucial differences between public health ethics and clinical ethics generate tensions in humanitarian health practice. We offer an analysis of some of the complexities this creates for humanitarian health care ethics, and consider ways of adjudicating between the two models. (shrink)

Health care professionals who travel from their home countries to participate in humanitarian assistance or development work experience distinctive ethical challenges in providing care and services to populations affected by war, disaster or deprivation. Limited information is available about organizational practices related to preparation and support for health professionals working with non-governmental organizations. In this article, we present one component of the results of a qualitative study conducted with 20 Canadian health care professionals who participated in international aid work. The (...) findings reported here relate to expatriate clinicians’ experiences and perceptions of ethics preparation, training and support. The strategies examined include pre-departure training and preparation, in-field supports and retrospective debriefing of ethical issues. Participants experienced a range of training and supports as beneficial for addressing ethical challenges in humanitarian assistance and development work. Participants also expressed ambivalence or scepticism about the benefits offered by specific modalities. This analysis can contribute to informing discussions of how organizations and individual practitioners can best develop, implement and utilize ethics training and support for international aid work.

This article explores the accounts of Canadian-trained health professionals working in humanitarian and development organizations who considered not treating a patient or group of patients because of resource limitations. In the narratives, not treating the patient(s) was sometimes understood as the right thing to do, and sometimes as wrong. In analyzing participants’ narratives we draw attention to how medications and equipment are represented. In one type of narrative, medications and equipment are represented primarily as scarce resources; in another, they are (...) represented as patient care. In the contexts respondents were working, medications and equipment were often both patient care interventions and scarce resources. The analytic point is that health professionals tend to emphasize one conceptualization over the other in coming to assert that not treating is right, or wrong. Rendering tacit ethical frameworks more explicit makes them available for reflection and debate. (shrink)

The concept of evolvability—the capacity of a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has a long history of investigating questions of evolvability, but paleontological thinking has tended to neglect recent discussions, because many tools used in the current evolvability literature are challenging to apply to the fossil record. The fundamental difficulty is how to disentangle whether the causes of evolutionary patterns arise from variational properties of traits or lineages rather than being (...) due to selection and ecological success. Despite these obstacles, the fossil record offers unique and growing sources of data that capture evolutionary patterns of sustained duration and significance otherwise inaccessible to evolutionary biologists. Additionally, there exist a variety of strategic possibilities for combining prominent neontological approaches to evolvability with those from paleontology. We illustrate three of these possibilities with quantitative genetics, evolutionary developmental biology, and phylogenetic models of macroevolution. In conclusion, we provide a methodological schema that focuses on the conceptualization, measurement, and testing of hypotheses to motivate and provide guidance for future empirical and theoretical studies of evolvability in the fossil record.

Three major strategies exist for the protection of endangered habitat and species: (1) land acquisition programs, (2) government legislation and regulatory agencies, and (3) "stewardship" programs that are voluntary and community-based. While all of these strategies have merit, we suggest that stewardship holds particular advantages and should be considered more often as a strategy of first choice. In this article, we examine the Municipal Wetland Stewardship program of Newfoundland, a popular and successful Canadian policy for the local protection of wetlands. (...) Important issues are at stake: competing philosophical foundations for managerial ecology, the value of "local ecological knowledge," principles of community-based conservation, the question of whether stewardship empowers local communities or controls them from afar, and ethical conflicts around American colonialism, hunting, and ecotourism. The results suggest that despite some potentially problematic ironies, the Newfoundland program provides a model for a public policy aimed both at the pragmatics of biophysical sustainability and at the ideals of environmental ethics, social justice, and democratic politics.

This essay collides with the aesthetic of wilderness cultivated by the North American retail chain Bass Pro Shops. Through elaborate displays and décor that render each store part rustic lodge, aquarium, amusement park, natural history museum, and hunting simulator, the stores represent the natural world and its inhabitants as abundant resources for human consumption. The stores’ aesthetic is primarily wrought through the arrangement of taxidermied animals. These animals include both traditional wildlife mounts posed in lifelike attitudes as well as animatronic (...) taxidermy that becomes “alive” in response to players’ achievements in a shooting range game. By exploring the stores’ traditional and animatronic taxidermy as well as its conflation of animal and machine, this essay explores the conception of environmental conservation and animal ontology upheld by Bass Pro Shops.

There can be no doubt that discrimination based on sex, race, ethnicity, religion or beliefs should not be tolerated in academia. Surprisingly, however, in recent years, policies of Diversity, Inclusion and Equity (DIE), officially introduced to counteract discrimination, have increasingly led to quite the opposite result: the exclusion of individuals who do not share a radical 'woke' ideology on identity politics (feminism, other gender activisms, critical race theory, etc.), and to the suppression of the academic freedom to discuss such dogmas. (...) This subversion of academia — disguised Trojan-horse style as universal human rights advocacy — is unacceptable because academia must be politically neutral and protect freedom of speech, a cornerstone of professional scholarly activity without which universities as we know them will slowly but surely suffocate. Our purpose here is to put together some particularly illustrative cases of such repression in a single book, testifying to a ubiquitous trend within western culture, irreducible to a few isolated complaints. The essays contained here illustrate the abuse of power, censorship and witch-hunts at many universities and research centres in the name of DIE.

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

We have arrived at an inflection point, a moment in history when the sentience, conscious- ness, intelligence, agency, and even the moral agency of many nonhuman animals can no longer be questioned without ignoring centuries of accumulated scientific knowledge. Nowhere is this more true than in our understanding of nonhuman primates (NHPs). A neu- roethics committed to probing the ethical implications of brain research must be able to respond to and anticipate the challenges ahead as brain projects globally prepare to (...) increase the use of NHPs in research. This requires adopting a less anthropocentric focus that includes nonhuman animals within its scope. But the Neuroethics Roadmap represents a missed opportunity to critically examine the future direction of research with NHPs in an ethically-responsive neuroscience. (shrink)

In acute inpatient mental health services, patients commonly demonstrate extreme behaviours. A number of coercive practices, such as locked doors, enforced medication and seclusion, are used in these settings to control such behaviours. The aim of this report is to explore briefly some of the contemporary debates pertaining to seclusion. A perusal of the literature reveals a clarion call to end the practice of seclusion, without consideration of feasible alternatives. It is hoped that this brief report will encourage further evidence-based (...) discussion and research initiatives on this important ethical topic. (shrink)

Locked inpatient units are an increasing phenomenon, introduced in response to unforseen abscondences and suicides of patients. This paper identifies some value issues concerning the practice of locked psychiatric inpatient units. Broad strategies, practicalities and ethical matters that must be considered in inpatient mental health services are also explored. The authors draw on the published research and commentary to derive relevant information to provide to patients and staff regarding the aims and rationales of locked units. Further debate is warranted in (...) relation to best practice. Inpatient staff need to be aware of their practice values, be able to access education and supervision and negotiate apparent contradictions. Further patient/clinician focused enquiry is necessary to mitigate the negative and stigmatising effects of locked mental health units. (shrink)

When clinical services aspire to quality improvement, creative and innovative approaches to old problems are needed to drive such change. Whilst new ef orts should be applauded, information on this topic can be somewhat grey from an ethical and research point of view. Within the mental health profession there is currently an expectation to routinely evaluate care and disseminate i ndings. The notion of service enhancements under the guise of routine practice is an interesting and untested ethical issue. Should clinical (...) innovation continue to enjoy such impunity as patient autonomy is often compromised as they are often compelled to accept treatment under the coercion of mental health legislation? We believe that it should not. All involvement in any form of research is voluntary, thus patients should also have the right to decline participation in quality projects if they wish to do so.

In their environment, plants are continuously submitted to natural stimuli such as wind, rain, temperature changes, wounding, etc. These signals induce a cascade of events which lead to metabolic and morphogenetic responses. In this paper the different steps are described and discussed starting from the reception of the signal by a plant organ to the final morphogenetic response. In our laboratory two plants are studied: Bryonia dioica for which rubbing the internode results in reduced elongation and enhanced radial expansion and (...) Bidens pilosa for which the response occurs at distance, hence pricking the cotyledon of a plantlet induces the growth inhibition of both the hypocotyl and the axillary bud of the pricked cotyledon. Reception of the signal and transmission of the message. In Bryonia the signal is received by epidermal cells while in Bidens they are the cells adjacent to the midrib of the cotyledon which receive the mechanical signal. In both plants the message is transmitted via a wave of electric depolarization. This latter is composed of an action potential associated with a slow wave whose transmission rates are respectively 1cm s−1 and 1 mm s−1. Recent results have shown the involvement of Ca2+ in the triggering of the slow wave and the role of the H+ pump during the slow wave. Transient and fast biochemical responses. An entry of extraceilular Ca2+ into the cells and a transient increase in IP3 occur within seconds following the mechanical stimulus. At the same time, the membrane becomes more fluid, correlated with qualitative changes in phospholipids. The rapid increase in the concentration of peroxidated lipids may be correlated with ethylene biosynthesis which is stimulated after rubbing. Other parameters such as cytoplasmic pH, relative water content, hydric potential, membrane potential and modifications of K+, Mg2+-ATPase and Ca2+-ATPase activities, play a key role in the early responses induced by the traumatisms. Irreversible-biochemical responses. The mechanical stimulus performed on a Bryonia internode induces an acceleration of: i) enzymatic activities related to the lignification, ii) esterification of phenolic acids in the cell wall. Consequently the lignification process is accelerated. Storage of the information. After being received by the target cells the information can be stored during several days before being expressed. At the level of cotyledonary bud, the first message, previously stored, can be expressed or not by a second treatment. Bidens thus behaves as if it was able to “store” and to “retrieve” morphogenetic messages, using a sort of rudimentary memory. The nuclei of the bud cells of the pricked cotyledon show that these cells, initially in G2 phase, divide and then remain in the G1 phase. In Bryonia, calli derived from young stimulated internodes, keep thigmomorphogenetic characteristics during several weeks. In the last part of this paper the particularity of our plant model which permits a study of the transmission and storage of the message, is underlined. The links between the different steps induced by the stimulus are discussed. Special attention is devoted to second messengers and to the amplification of the message. (shrink)

The connection between similarity logic and the theory of closure operators is examined. Indeed one proves that the consequence relation defined in [14] can be obtained by composing two closure operators and that the resulting operator is still a closure operator. Also, we extend any similarity into a similarity which is compatible with the logical equivalence, and we prove that this gives the same consequence relation.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

The introduction of novel diagnostic techniques in clinical domains such as genomics and radiology has led to a rich ethical debate on how to handle unsolicited findings that result from these innovations. Yet while unsolicited findings arise in both genomics and radiology, most of the relevant literature to date has tended to focus on only one of these domains. In this article, we synthesize and critically assess similarities and differences between “scanning the body” and “sequencing the genome” from an ethical (...) perspective. After briefly describing the novel diagnostic contexts leading to unsolicited findings, we synthesize and reflect on six core ethical issues that relate to both specialties: terminology; benefits and risks; autonomy; disclosure of unsolicited findings to children; uncertainty; and filters and routine screening. We identify ethical rationales that pertain to both fields and may contribute to more ethically sound policies. Considerations of preserving public trust and ensuring that people perceive healthcare policies as fair also support the need for a combined debate. (shrink)

For more than sixty years, surgeons have used bioethical strategies to promote patient self‐determination, many of these now collectively described as “informed consent.” Yet the core framework—understanding, risks, benefits, and alternatives—fails to support patients in deliberation about treatment. We find that surgeons translate this framework into an overly complicated technical explanation of disease and treatment and an overly simplified narrative that surgery will “fix” the problem. They omit critical information about the goals and downsides of surgery and present untenable options (...) as a matter of patient choice. We propose a novel framework called “better conversations.” Herein, surgeons provide context about clinical norms, establish the goals of surgery, and comprehensively delineate the downsides of surgery to generate a deliberative space for patients to consider whether surgery is right for them. This paradigm shift meets the standards for informed consent, supports deliberation, and allows patients to anticipate and prepare for the experience of treatment. (shrink)

The best-interests standard is a widely used ethical, legal, and social basis for policy and decision-making involving children and other incompetent persons. It is under attack, however, as self-defeating, individualistic, unknowable, vague, dangerous, and open to abuse. The author defends this standard by identifying its employment, first, as a threshold for intervention and judgment (as in child abuse and neglect rulings), second, as an ideal to establish policies or prima facie duties, and, third, as a standard of reasonableness. Criticisms of (...) the best-interests standard are reconsidered after clarifying these different meanings. (shrink)

İslami finans, klasik iktisadi düzenin temel taşı sayılabilecek faizi finansal sistemin dışında bırakarak adil, kapsayıcı ve sömürüden uzak alternatif bir finansal sistem olarak ortaya çıkmıştır.

Bugün katılım bankaları sorunlu kredilerinin çözümü noktasında konvansiyonel bankalara çok benzeyen aksiyonlar almaktadır ki bunlardan biri de sorunlu kredi dosyalarının varlık yönetim şirketlerine satılmasıdır. Bu durum sistemin “İslami” oluşunu tehdit etmektedir. Bu çalışmada ülkemizdeki katılım bankalarında sorunlu krediler ve katılım bankalarının varlık yönetim şirketleri ile ilişkileri incelenmiş olup İslami finansın ana akım finansal sistem olarak kullanıldığı bazı ülkeler ile çeşitli sosyoekonomik kıstaslar açısından ülkemizle benzeşen bazı ülkelerde sorunlu kredilerin nasıl çözümlendiği incelenerek ülkemizdeki uygulamalara yönelik öneriler sunmak amaçlanmıştır.

Background: The factors influencing parents’ willingness to enroll their children in biobanks are poorly understood. This study sought to assess parents’ willingness to enroll their children, and their perceived benefits, concerns, and information needs under different consent and data-sharing scenarios, and to identify factors associated with willingness. Methods: This large, experimental survey of patients at the 11 eMERGE Network sites used a disproportionate stratified sampling scheme to enrich the sample with historically underrepresented groups. Participants were randomized to receive one of (...) three consent and data-sharing scenarios. Results: In total, 90,000 surveys were mailed and 13,000 individuals responded (15.8% response rate). 5737 respondents were parents of minor children. Overall, 55% (95% confidence interval 50–59%) of parents were willing to enroll their youngest minor child in a hypothetical biobank; willingness did not differ between consent and data-sharing scenarios. Lower educational attainment, higher religiosity, lower trust, worries about privacy, and attitudes about benefits, concerns, and information needs were independently associated with less willingness to allow their child to participate. Of parents who were willing to participate themselves, 25% were not willing to allow their child to participate. Being willing to participate but not willing to allow one’s child to participate was independently associated with multiple factors, including race, lower educational attainment, lower annual household income, public health care insurance, and higher religiosity. Conclusions: Fifty-five percent of parents were willing to allow their youngest minor child to participate in a hypothetical biobank. Building trust, protecting privacy, and addressing attitudes may increase enrollment and diversity in pediatric biobanks. (shrink)

Criticisms of the ethical justification of antidoping legislation are not uncommon in the literatures of medical ethics, sports ethics and sports medicine. Critics of antidoping point to inconsistencies of principle in the application of legislation and the unjustifiability of ethical postures enshrined in the World Anti-Doping Code, a new version of which came into effect in January 2009. This article explores the arguments concerning the apparent legal peculiarities of antidoping legislation and their ethically salient features in terms of: notions of (...) culpability, liability and guilt; aspects of potential duplication of punishments and the limitations of athlete privacy in antidoping practice and policy. It is noted that tensions still exist between legal and ethical principles and norms that require further critical attention. (shrink)

In this paper we focus on the modularity of visual functions in the human visual cortex, that is, the specific problems that the visual system must solve in order to achieve recognition of objects and visual space. The computational theory of early visual functions is briefly reviewed and is then used as a basis for suggesting computational constraints on the higher-level visual computations. The remainder of the paper presents neurological evidence for the existence of two visual systems in man, one (...) specialized for spatial vision and the other for object vision. We show further clinical evidence for the computational hypothesis that these two systems consist of several visual modules, some of which can be isolated on the basis of specific visual deficts which occur after lesions to selected areas in the visually responsive brain. We will provide examples of visual modules which solve information processing tasks that are mediated by specific anatomic areas. We will show that the clinical data from behavioral studies of monkeys (Ungerleider and Mishkin 1984) supports the distinction between two visual systems in monkeys, the 'what' system, involved in object vision, and the 'where' system, involved in spatial vision.
