Dental caries is the main oral health challenge for children in Nigeria. Concern about its negative impact makes screening for caries in children an attractive public health strategy. The ability to detect the preclinical phase of caries, the availability of screening tools with high accuracy, and the possibility of treatment before onset of clinical symptoms with significant cost and health benefits, makes it appropriate for screening. However in Nigeria, the poor availability of highly specific and sensitive screening tools, poor access (...) to oral health care and concerns with pre-screening consent, raise the question of the appropriateness of conducting screening programmes for children. We argue that a number of structural challenges associated with poor uptake of oral health care services need to be addressed before screening for caries can be considered ethically appropriate. These include facilitating access of children to quality oral health care and a systematic national approach to oral health impl... (shrink)

Published data show that new HIV prevention strategies including treatment‐as‐prevention and pre‐exposure prophylaxis (PrEP) using oral antiretroviral drugs (ARVs) are highly, but not completely, effective if regimens are taken as directed. Consequently, their implementation may challenge norms around HIV prevention. Specific concerns include the potential for ARV‐based prevention to reframe responsibility, erode beneficial sexual norms and waste resources. This paper explores what rights claims uninfected people can make for access to ARVs for prevention, and whether moral claims justify the provision (...) of ARV therapy to those who do not yet clinically require treatment as a way of reducing HIV transmission risk. An ethical analysis was conducted of the two strategies, PrEP and treatment‐as‐prevention, using a public health stewardship model developed by the Nuffield Bioethics Council to consider and compare the application of PrEP and treatment‐as‐prevention strategies. We found that treating the person with HIV rather than the uninfected person offers advantages in settings where there are limited opportunities to access care. A treatment‐as‐prevention strategy that places all the emphasis upon the positive person's adherence however carries a disproportionate burden of responsibility. PrEP remains an important option for receptive partners who face increased biological vulnerability. We conclude that the use of ARV for prevention is ethically justified, despite imperfect global to drugs for those in clinical need. The determination of which ARV‐based HIV prevention strategy is ethically preferable is complex and must take into account both public health and interpersonal considerations. (shrink)

Vaccination is a highly effective public health strategy that provides protection to both individuals and communities from a range of infectious diseases. Governments monitor vaccination rates carefully, as widespread use of a vaccine within a population is required to extend protection to the general population through “herd immunity,” which is important for protecting infants who are not yet fully vaccinated and others who are unable to undergo vaccination for medical or other reasons. Australia is unique in employing financial incentives to (...) increase vaccination uptake, mainly in the form of various childcare payments and tax benefits linked to timely, age-appropriate vaccination. Despite relatively high compliance with the childhood vaccination schedule, however, the Australian government has determined that rates should be higher and has recently introduced policy that includes removing certain tax and childcare benefits for non-vaccinators and formally disallowing conscientious objection to vaccination. In addition, it has raised the possibility of banning unvaccinated children from childcare centres. This article examines the impact of coercive approaches to childhood vaccination and raises the question of the ethical justification of health policy initiatives based on coercion. We consider the current evidence regarding childhood vaccination in Australia, the small but real risks associated with vaccination, the ethical requirement for consent for medical procedures, and the potential social harms of targeting non-vaccinators. We conclude that the evidence does not support a move to an increasingly mandatory approach that could only be delivered through paternalistic, coercive clinical practices. (shrink)

In 2010, randomized controlled trials (RCTs) of two different biomedical strategies to prevent HIV infection had positive findings. However, despite ongoing very high levels of HIV infection in some countries and population groups, it has been made clear by regulatory authorities that the evidence remains insufficient to support either product being made available outside of research contexts in the developing world for at least two years. In addition, prevention trials in endemic areas will continue to test new interventions against placebo. (...) But the judgments of evidentiary standards are never value-neutral. Using the recent trials and their contexts as case studies, we examine the basis for these decisions, which will potentially delay access to scientific innovation to the people who are most urgently in need of it.

The principle of providing post-trial access for research participants to successful products of that research is widely accepted and has been enshrined in various declarations and guidelines. While recent ethical guidelines recognise that the responsibility to provide post-trial access extends to sponsors, regulators and government bodies as well as to researchers, it is the researchers who have the direct duty of care to participants. Researchers may thus need to act as advocates for trial participants, especially where government bodies, sponsors, and (...) regulatory bodies have complex interests vested in decisions about whether or not new interventions are made available, how, and to whom. This paper provides an empirical account of post-trial access in the context of HIV prevention research. It describes both access to the successful products of research and the provision antiretroviral drugs for trial participants who acquire HIV. First, we provide evidence that, in the current system, there is considerable variation in the duration and timeliness of access. We then argue that by analysing the difficulties faced by researchers to this point, and their efforts to meet this obligation, much can be learned about how to secure post-trial access in HIV biomedical preventions trials. While researchers alone have a limited obligation, their advocacy on behalf of trial participants may be necessary to call the other parties to account. (shrink)

The successful demonstration that antiretroviral (ARV) drugs can be used in diverse ways to reduce HIV acquisition or transmission risks – either taken as pre-exposure prophylaxis (PrEP) by those who are uninfected or as early treatment for prevention (T4P) by those living with HIV – expands the armamentarium of existing HIV prevention tools. These findings have implications for the design of future HIV prevention research trials. With the advent of multiple effective HIV prevention tools, discussions about the ethics and the (...) feasibility of future HIV prevention trial designs have intensified. This article outlines arguments concerning the inclusion of newly established ARV-based HIV prevention interventions as standard of prevention in HIV prevention trials from multiple perspectives. Ultimately, there is a clear need to incorporate stakeholders in a robust discussion to determine the appropriate trial design for each study population. (shrink)

In many countries around the world, people who inject drugs remain at high risk of HIV acquisition not because effective forms of prevention are unknown, nor because they find effective prevention undesirable, but because those in charge, mainly politicians but also bureaucrats, find evidence-based practice politically unacceptable. The evidence for preventive efficacy of harm reduction strategies, most prominently needle and syringe programmes but also treatment programmes such as opiate substitution, is irrefutable.1 However, political responses to drug use issues are varied (...) and complex, so the will to implement appropriate harm reduction programmes in the interests of public health remains lacking in too many jurisdictions. As a consequence, the discussion of how best, in the context of research, to reduce HIV incidence in populations of people who inject drugs but are not offered comprehensive access to known prevention strategies is—tragically—an important one. Dawson et al 2 focus on access to sterile injecting equipment and recognise that this should remain the ‘default’ standard of prevention for HIV prevention trials involving people for whom injecting drug use is the primary risk factor for HIV acquisition. ‘Standard of prevention’ means the background or minimal HIV risk reduction interventions offered to all participants in a trial, regardless of what other investigational interventions they are assigned to receive. The standard of prevention concept is grounded in the ethical principle of beneficence—that researchers and sponsors are obliged to maximise benefits and minimise risks to participants in research studies.3 ….

In clinical research there is a tension between the role of a doctor, who must serve the best interests of the patient, and the role of the researcher, who must produce knowledge that may not have any immediate benefits for the research participant. This tension is exacerbated in HIV research in low and middle income countries, which frequently uncovers comorbidities other than the condition under study. Some bioethicists argue that as the goals of medicine and those of research are distinct, (...) it is a mistake for researchers to assume therapeutic responsibilities while engaging in research. Others propose that there is a duty of care, but disagree as to how this is limited and specified. In this qualitative study, principal investigators from HIV prevention trials discuss their experience of providing medical benefits to participants within the context of conducting research into HIV biomedical prevention technologies. They describe the limitations imposed at times by funders and at times by infrastructure constraints, and canvass the importance of ancillary care provision and capacity building in trial communities. The views of the principal investigators are compatible with the perspective that there is a duty of care, limited by the nature of the research, the depth of the relationship between research and participant, and the capacity of the research site. The therapeutic orientation in HIV prevention trial appears to be indivisible from competent research practise by making concrete and appropriate benefits available to trial participants and their communities that support rather than compete with local infrastructure.

This article examines the relationship between bioethics and the therapeutic standards in HIV prevention research in the developing world, focusing on the closure of the pre-exposure prophylaxis (PrEP) trials in the early 2000s. I situate the PrEP trials in the historical context of the vertical transmission debates of the 1990s, where there was protracted debate over the use of placebos despite the existence of a proven intervention. I then discuss the dramatic improvement in the clinical management of HIV and the (...) treatment access movement, and consider how these contexts have influenced research practice. I argue that as HIV prevention trials oblige researchers to observe the rate at which vulnerable people under their care acquire HIV, there is an obligation to provide antiretroviral treatment to seroconverters and other health care benefits that fall within the scope of researchers' entrustment, both to avoid exploitation and to enact reciprocal justice. I argue against propositions that the obligations to provide specific benefits are vague, fall only upon researchers and sponsors, and create injustices by privileging the few over the many. Finally, I contend that the realisation of a broader standard of care in HIV prevention research broadens the role of research from being a simple tool to produce knowledge to a complex intervention that can play a part in the reduction of health disparities.

In his article ‘The Ebola Clinical Trials: a precedent for research ethics in disasters’, Philippe Calain constructs a compelling case as to why and how experiences from the recent Ebola epidemic should be used to develop a framework for disaster research ethics. In particular, Calain proposes a useful model for assessing whether or not an unproven intervention could be suitable for human use in a disaster context, and makes a powerful argument against the separation of patient care from research goals. (...) In this commentary, I argue that the separation of patient care goals from research goals is also unhelpful in the context of other forms of participant disadvantage even when that disadvantage is less severe than an ongoing public health emergency. I contend that recognising that research in disadvantaged populations is an intervention that could and should aim to produce positive outcomes for participants, just as it should in disaster contexts, therefore seems a well-justified lesson that can be extrapolated from the experience of the Ebola epidemic.

In July 2012, based on evidence from two major trials, the United States Food and Drug Administration approved the use of combined oral tenofovir/emtricitabine as pre-exposure prophylaxis for people at high risk of HIV acquisition. PrEP effectiveness is marred by poor adherence, however, even in trial populations, thus it is not a magic bullet for HIV prevention. It is, however, the most effective biomedical HIV prevention intervention available for people at high risk of HIV, particularly those who have receptive sex (...) and lack the power to negotiate condom use. Accordingly, there are compelling reasons to compare future experimental HIV prevention interventions against PrEP. The interests both of trial participants and of science are served by using PrEP as comparator: Not only would HIV incidence be reduced, but also the question of whether new interventions were superior to best proven interventions, in a given setting, would be answered comprehensively.

In their recent paper‘Undue inducement: a case study in CAPRISA 008’, Mngadi et al conclude that a participant in an HIV prevention study who deliberately concealed her pregnancy was not ‘unduly induced’ to participate by the offer of an experimental product. This paper argues that while the authors’ conclusion is sound, the framing of this case study is consistent with the preoccupation in research ethics with the concept of undue inducement, coupled with a highly risk-averse attitude to pregnancy. We suggest (...) that the critical research ethics question raised by Mngadi et al ’s case study is not ‘undue inducement’, but the exclusion of pregnant women from research studies where the risks are acceptable to the potential participant, and benefits likely. We also suggest that current regulatory paradigms regarding pregnancy are both overly paternalistic and value the fetus over the mother. In order to ensure timely provision of new HIV prevention agents, we argue that there is a need for expeditious testing of proven effective agents in pregnancy, with due consideration given to situations where preliminary efficacy data exist but fall short of licensure standards. This requires a paradigm shift from researchers, funders, regulators and ethical review bodies towards practices that critically examine the legitimacy of the exclusion of pregnant women on a study-by-study basis.

There is increasing interest in the need to address the ethical dilemmas related to the engagement of adolescents in sexual and reproductive health research. Research projects, including those that address issues related to STIs and HIV, adverse pregnancy outcomes, violence, and mental health, must be designed and implemented to address the needs of adolescents. Decisions on when an individual has adequate capacity to give consent for research most commonly use age as a surrogate rather than directly assessing capacity to understand (...) the issues and make an informed decision on whether to participate in research or not. There is a perception that adolescents participating in research are more likely to be coerced and may therefore not fully comprehend the risk they may be taking when engaging in research. This paper examines the various ethical issues that may impact stakeholders' decision making when considering engaging adolescents in SRH research in Nigeria. It makes a case for lowering the age of consent for adolescents. While some experts believe it is possible to extrapolate relevant information from adult research, studies on ethical aspects of adolescents' participation in research are still needed, especially in the field of sexual and reproductive health where there are often differences in knowledge, attitudes and practices compared to adults. The particular challenges of applying the fundamental principles of research ethics to adolescent research, especially research about sex and sexuality, will only become clear if more studies are conducted.

Visual research methods like photography and digital storytelling are increasingly used in health and social sciences research as participatory approaches that benefit participants, researchers, and audiences. Visual methods involve a number of additional ethical considerations such as using identifiable content and ownership of creative outputs. As such, ethics committees should use different assessment frameworks to consider research protocols with visual methods. Here, we outline the limitations of ethics committees in assessing projects with a visual focus and highlight the sparse knowledge (...) on how researchers respond when they encounter ethical challenges in the practice of visual research. We propose a situated approach in relation to visual methodologies that encompasses a negotiated, flexible approach, given that ethical issues usually emerge in relation to the specific contexts of individual research projects. Drawing on available literature and two case studies, we identify and reflect on nuanced ethical implications in visual research, like tensions between aesthetics and research validity. The case studies highlight strategies developed in-situ to address the challenges two researchers encountered when using visual research methods, illustrating that some practice implications are not necessarily addressed using established ethical clearance procedures. A situated approach can ensure that visual research remains ethical, engaging, and rigorous. (shrink)

BackgroundThe global interest in developing therapies for Ebola infection management and its prevention is laudable. However the plan to conduct an emergency immunization program specifically for healthcare workers using experimental vaccines raises some ethical concerns. This paper shares perspectives on these concerns and suggests how some of them may best be addressed.DiscussionThe recruitment of healthcare workers for Ebola vaccine research has challenges. It could result in coercion of initially dissenting healthcare workers to assist in the management of EVD infected persons (...) due to mistaken beliefs that the vaccine offers protection. It could also affect equity and justice. For example, where people who are not skilled health care professionals but who provide care to patients infected with Ebola are not prioritized for vaccination. The possibility of study participants contracting Ebola infection despite the use of experimental vaccine, and the standard of care they would receive, needs to be addressed clearly, transparently and formalized as part of the ethics review process. Future access to study products in view of current status of the TRIPS agreement needs to be addressed. Finally, broad stakeholder engagement at local, regional and international levels needs to be promoted using available communication channels to engage local, regional and international support. These same concerns are applicable for current and future epidemics.SummarySuccessful Ebola vaccine development research requires concerted efforts at public dialogue to address misconceptions, equity and justice in participant selection, and honest discussions about risks, benefits and future access. Public dialogue about Ebola vaccine research plans is crucial and should be conducted by trusted locals and negotiated between communities, researchers and ethics committees in research study sites.

In late March 2020 in response to the COVID-19 pandemic, Australia introduced mandatory 14-day supervised quarantine at hotels and other designated facilities for all international arrivals. From July 2020, most states and territories introduced a fixed charge for quarantine of up to $3220 per adult. The introduction of the fee was rationalised on the basis that Australians had been allowed sufficient time to return and there was a need to recover some of the cost associated with administering the program. Drawing (...) on an empirical study of 58 returned Australian citizens and residents quarantined between March 2020 and January 2021, this paper aims to explore how people experienced paying for hotel quarantine, particularly with respect to fairness and relatedly, the principle of reciprocity. Reciprocity requires that the state has an obligation to assist individuals in discharging their duty to comply with public health measures and avoid disproportionate burdens accruing to populations or individuals. Though participants had varying opinions on whether they thought it fair to be charged for their quarantine, for many, the fee constituted a significant burden and source of stress. Given the undertaking of quarantine is primarily for the benefit of the public good, we argue the financial cost imposed on individuals does not meet the demands of reciprocity. It is imperative that future quarantine and isolation arrangements consider seriously the need to minimise burdens of individuals subject to such measures, and that fees do not become a new norm in public health and infectious disease control.

HIV prevention is a critical health issue in Nigeria; a country that has one of the worst HIV epidemic profiles in the world. With 270,000 new infections in 2012, Nigeria is a prime site for HIV prevention research. One effect of the HIV epidemic has been to revolutionalise ethical norms for the conduct of research: it is now considered unethical to design and implement HIV related studies without community engagement. Unfortunately, there is very little commensurate effort in building the capacity (...) of local persons to engage actively with researchers, and there is no existing platform to facilitate dialogue between researchers and communities engaged in research in Nigeria. In an effort to address this gap, we undertook a series of three community dialogues and two community-researcher interface meetings in Nigeria. This paper aims to give an empirical account of the dialogue from these community engagement processes and provide a resulting critique of the implementation of research ethics practices in Nigeria. It is anticipated that the outputs will: support researchers in designing community-based research protocols; inform ethics committees of key considerations during research protocol reviews from a community perspective; and inform policy makers and research sponsors about issues of primary concern to communities with respect to HIV research.

Community engagement in research, including public health related research, is acknowledged as an ethical imperative. While medical care and public health action take priority over research during infectious disease outbreaks, research is still required in order to learn from epidemic responses. The World Health Organisation developed a guide for community engagement during infectious disease epidemics called the Good Participatory Practice for Trials of Emerging (and Re‐emerging) Pathogens that are Likely to Cause Severe Outbreaks in the Near Future and for which (...) Few or No Medical Counter‐Measures Exist (GPP‐EP). This paper identified priorities for community engagement for research conducted during infectious disease outbreaks drawing on discussions held with a purposive sample of bioethicists, social scientists, researchers, policy makers and laypersons who work with ethics committees in West Africa. These perspectives were considered in the light of the GPP‐EP, which adds further depth and dimension to discussions on community engagement frameworks. It concludes that there is no presumptive justification for the exclusion of communities in the design, implementation and monitoring of clinical trials conducted during an infectious disease outbreak. Engagement that facilitates collaboration rather than partnership between researchers and the community during epidemics is acceptable. (shrink)

ABSTRACT The aim of this study is to determine how stakeholder engagement can be adapted for the conduct of COVID‐19‐related clinical trials in sub‐Saharan Africa. Nine essential stakeholder engagement practices were reviewed: formative research; stakeholder engagement plan; communications and issues management plan; protocol development; informed consent process; standard of prevention for vaccine research and standard of care for treatment research; policies on trial‐related physical, psychological, financial, and/or social harms; trial accrual, follow‐up, exit trial closure and results dissemination; and post‐trial access (...) to trial products or procedures. The norms, values, and practices of collectivist societies in Sub‐Saharan Africa and the low research literacy pose challenges to the conduct of clinical trials. Civil‐society organizations, members of community advisory boards and ethics committees, young persons, COVID‐19 survivors, researchers, government, and the private sector are assets for the implementation and translation of COVID‐19 related clinical trials. Adapting ethics guidelines to the socio‐cultural context of the region can facilitate achieving the aim of stakeholder engagement. (shrink)

This article investigates whether or not theories of justice from political philosophy, first, support the position that health research should contribute to justice in global health, and second, provide guidance about what is owed by international clinical research (ICR) actors to parties in low- and middle-income countries. Four theories—John Rawls's theory of justice, the rights-based cosmopolitan theories of Thomas Pogge and Henry Shue, and Jennifer Ruger's health capability paradigm—are evaluated. The article shows that three of the four theories require the (...) conduct of health research for justice in global health. The theories help identify the ends of justice to which ICR is to contribute, but they cannot tell us how to organize ICR to promote these ends. Aside from Ruger's health capability paradigm, the theories also lack an allocative principle for assigning specific duties to specific actors. This creates difficulties for establishing obligations for certain types of ICR actors. (shrink)

ABSTRACT Abduction as a method for sociological explanation is increasingly gaining interest, but questions remain as to what exactly it is and how it differs from other methods of inquiry. This paper compares abduction as conceived in Peircean pragmatism with the critical realist concept of retroduction. I argue that abduction in the Peircean sense and retroduction in the critical realist sense refer to different, but complementary, modes of inference. Abductive conclusions provide the starting point for retroductive inferences; the latter inform (...) the tenability of the former. Together, abduction and retroduction contribute to theoretical explanation. (shrink)

Research from cognitive science and geoscience education has shown that sketching can improve spatial thinking skills and facilitate solving spatially complex problems. Yet sketching is rarely implemented in introductory geosciences courses, due to time needed to grade sketches and lack of materials that incorporate cognitive science research. Here, we report a design-centered, collaborative effort, between geoscientists, cognitive scientists, and artificial intelligence researchers, to characterize spatial learning challenges in geoscience and to design sketch activities that use a sketch-understanding program, CogSketch. We (...) developed 26 CogSketch worksheets that use cognitive science–based principles to scaffold problem solving of spatially complex geoscience problems and report observations of an implementation in an introductory geoscience course where students used CogSketch or human-graded paper worksheets. Overall, this research highlights the principles of interdisciplinary design between cognitive scientists, geoscientists, and AI researchers that can inform the collaborative design process for others aiming to develop effective educational materials.

A number of recent studies have revealed correspondences between song- and language-related neural structures, pathways, and gene expression in humans and songbirds. Analyses of vocal learning, song structure, and the distribution of song elements have similarly revealed a remarkable number of shared characteristics with human speech. This article reviews recent developments in the understanding of these issues with reference to the phonological phenomena observed in human language. This investigation suggests that birds possess a host of abilities necessary for human phonological (...) computation, as evidenced by behavioral, neuroanatomical, and molecular genetic studies. Vocal-learning birds therefore present an excellent model for studying some areas of human phonology, though differences in the primitives of song and language as well as the absence of a human-like morphosyntax make human phonology differ from birdsong phonology in crucial ways.

We propose an account of dynamic predicates which draws on the notion of force, eliminating reference to events in the linguistic semantics. We treat dynamic predicates as predicates of forces, represented as functions from an initial situation to a final situation that occurs ceteris paribus, that is, if nothing external intervenes. The possibility that opposing forces might intervene to prevent the transition to a given final situation leads us to a novel analysis of non-culminating accomplishment predicates in a variety of (...) languages, including the English progressive. We then apply the force-theoretic framework to the composition of basic Vendlerian eventuality types within a lexical-decomposition syntax. The difference between predicates of forces and predicates of situations is argued to underlie the dynamic/stative contrast, and also to allow for a formal treatment of the difference between be and stay. Consequences for the relationship between language and cognition are discussed. (shrink)

Although organizational and situational factors have been found to predict burnout, not everyone employed at the same workplace develops it, suggesting that becoming burnt out is a complex, multifaceted phenomenon. The aim of this study was to elucidate perceptions of conscience, stress of conscience, moral sensitivity, social support and resilience among two groups of health care personnel from the same workplaces, one group on sick leave owing to medically assessed burnout (n = 20) and one group who showed no indications (...) of burnout (n = 20). The results showed that higher levels of stress of conscience, a perception of conscience as a burden, having to deaden one’s conscience in order to keep working in health care and perceiving a lack of support characterized the burnout group. Lower levels of stress of conscience, looking on life with forbearance, a perception of conscience as an asset and perceiving support from organizations and those around them (social support) characterized the non-burnout group.

Difficulties and ambiguities of Carnap’s conception of logic and mathematics are the main target of Gödel’s analysis in his famous drafts of “Is mathematics Syntax of Language?”. In a recent article, Gregory Lavers discusses two main recent dismissive analyses of Gödel’s drafts, concluding at a defense of Gödel’s arguments against Carnap’s position in the 1930. Lavers partially integrates in his examination an argument that I presented in a paper published in 2003. Yet, there are three important differences between my understanding (...) of Gödel’s argument and Lavers’s interpretation of it. These differences concern the appreciation of (a) Gödel’s strategy of using, in any critical examination of his opponents, only arguments that can be accepted by them; (b) Gödel’s analysis of Carnap’s position in the 1950s; (c) Gödel’s understanding of Carnap’s philosophical project. The paper aims to argue that, contrary to Lavers’s opinion, Gödel takes seriously the details of Carnap’s original conception and does not overlook the novelty of its solutions in the 1930s and 1950s. In particular, the comparison between Gödel’s arguments in the Gibbs lecture of 1951 and in version III of his draft of ‘Is mathematics Syntax of Language?’ shows how Gödel had in 1953–55 a careful concern with Carnap’s philosophical project of LSL.

Both autistic adults and families of autistic children rely heavily on blogs and other digital platforms to create community and gain experiential knowledge about autism, but research on autism blogs has failed to distinguish between the perspectives of autistic adults and neurotypical parent bloggers. Furthermore, intersections in the experiences of BIPOC autistics are rarely examined. Using a content analysis with a feminist Critical Disability Studies lens, I explore six autism parent blogs from diverse demographics: a white neurotypical father, a white (...) autistic mother in an interracial relationship, a white neurotypical mother, an Indigenous autistic trans father, a Black autistic nonbinary mother, and a Black neurotypical mother. I examine the attitudes of these bloggers to get a sampling of their opinions on autism, how they parent autistic children, and how their social location, specifically race, impacts their experiences. More intersectional research needs to be done to boost the perspectives of BIPOC autistics and the expertise of autistic parents. (shrink)

With evidence of vaccine hesitancy in several jurisdictions, the option of making COVID-19 vaccination mandatory requires consideration. In this paper I argue that it would be ethical to make the COVID-19 vaccination mandatory for older people who are at highest risk of severe disease, but if this were to occur, and while there is limited knowledge of the disease and vaccines, there are not likely to be sufficient grounds to mandate vaccination for those at lower risk. Mandating vaccination for those (...) at high risk of severe disease is justified on the basis of the harm principle, as there is evidence that this would remove the grave public health threat of COVID-19. The risk–benefit profile of vaccination is also more clearly in the interests of those at highest risk, so mandatory vaccination entails a less severe cost to them. Therefore, a selective mandate would create fairness in the distribution of risks. The level of coercion imposed by a mandate would need to be proportionate, and it is likely that multiple approaches will be needed to increase vaccine uptake. However, a selective mandate for COVID-19 vaccines is likely to be an ethical choice and should be considered by policy-makers. (shrink)

Employers are not only looking for generic `foreignness' (...) however, but typically also seek particular nationalities or ethnicities of worker, which can raise difficulties for agencies who are not allowed to discriminate on the basis of `race'.

In order to fulfill ABET requirements, Northern Arizona University’s Civil and Environmental engineering programs incorporate professional ethics in several of its engineering courses. This paper discusses an ethics module in a 3rd year engineering design course that focuses on the design process and technical writing. Engineering students early in their student careers generally possess good black/white critical thinking skills on technical issues. Engineering design is the first time students are exposed to “grey” or multiple possible solution technical problems. To identify (...) and solve these problems, the engineering design process is used. Ethical problems are also “grey” problems and present similar challenges to students. Students need a practical tool for solving these ethical problems. The step-wise engineering design process was used as a model to demonstrate a similar process for ethical situations. The ethical decision making process of Martin and Schinzinger was adapted for parallelism to the design process and presented to students as a step-wise technique for identification of the pertinent ethical issues, relevant moral theories, possible outcomes and a final decision. Students had greatest difficulty identifying the broader, global issues presented in an ethical situation, but by the end of the module, were better able to not only identify the broader issues, but also to more comprehensively assess specific issues, generate solutions and a desired response to the issue.
