Given Kim’s principle of explanatory exclusion (EE), it follows that in addition to the problem of mental causation, dualism faces a problem of mental explanation. However, the plausibility of EE rests upon the acceptance of a further principle concerning the individuation of explanation (EI). The two methods of defending EI—either by combining an internal account of the individuation of explanation with a semantical account of properties or by accepting an external account of the individuation of explanation—are both metaphysically implausible. This (...) is not, however, to reject the problem of mental explanation, for EE can be replaced with a far weaker principle, which does not require the acceptance of EI, but which generates a similar problem for dualism.

Proponents of the subset account of property realization commonly make the assumption that the summing of properties entails the summing of their forward-looking causal features. This paper seeks to establish that this assumption is false. Moreover, it aims to demonstrate that without this assumption the fact that the subset account captures an entailment relation—which it must if it is to be of any use to non-reductive physicalism—becomes questionable.

Le Poidevin has recently presented an argument that gives rise to a serious problem for relationist theories of space. It appeals to the simple geometrical fact that if A, B and C are three points lying in a straight line, then AB and BC together entail AC. He suggests that an ontological relationship of supervenience must be appealed to to explain this entailment. Given this thesis of supervenience, relationism is implausible. I argue that the problem that Le Poidevin raises for (...) relationism should be rejected, because the thesis of supervenience is false. The latter rests upon what Le Poidevin refers to as ‘The explanatory principle', a principle which he claims to be a natural extension of the truthmaker principle. Contrary to this, I argue that given any plausible theory of truthmaking, the explanatory principle is false. With the rejection of this principle, Le Poidevin's argument against relationism collapses. (shrink)

Recently, the European Union decreed that European countries should use disclosures of brand placement in programs and movies on television to guarantee fair communication. However, an understanding of the effects of disclosing brand placement is lacking. The present study is the first to test the impact of the new TV sponsorship regulations regarding disclosure of brand placement. In an experiment, we examine viewers’ opinions about disclosures along with the effects of disclosure timings. Analyses show that brand memory increases when a (...) disclosure is shown. In addition, brand memory is significantly higher when the disclosure is shown during the placement than when it is shown after the placement. Disclosures do not seem to activate critical attitudes. Respondents confronted with a disclosure, regardless of the timing, were not more skeptical towards brand placement than respondents who were not exposed to a disclosure. These findings have important implications for theory and public policy regarding brand placement disclosures. (shrink)

I defend a dualist model of psychophysical causal relevance, according to which mental events are not causes in the physical domain, but are causally relevant in this domain because they enable — or, in other words, provide the appropriate structure for — physical events to be caused. More specifically, I defend the claim that mental events are ‘double preventers’ within the physical domain, where double preventers are a type of enabling event. The distinction that I make between causes and enabling (...) events and the dualist model of psychophysical causal relevance that I defend has emerged from my acceptance of the powers theory of causation. In this paper, I explore how this dualist model of psychophysical causal relevance offers a response to Papineau’s defence of the causal completeness principle via the conservation laws. (shrink)

According to one popular criterion of property identity, where X and Y are properties, X is identical with Y if and only if X and Y bestow the same conditional powers on their bearers. In this paper, I argue that this causal criterion of property identity is unsatisfactory, because it fails to provide a sufficient condition for the identification of properties. My argument for this claim is based on the observation that the summing of properties does not entail the summing (...) of the conditional powers that they bestow on an object, but, rather, in some cases their subtraction. If so, the following causal structure seems possible: There are two properties, A and B. Each bestows a different set of conditional powers on its bearer, but the conjunctive property A-and-B bestows exactly the same set of conditional powers as either A or B. If this causal structure is possible, then it creates a serious problem for the causal criterion of property identity. (shrink)

During mammalian development, maintenance of cell fate through mitotic divisions require faithful replication not only of the DNA but also of a particular epigenetic state. Germline cells have the capacity of erasing this epigenetic memory at crucial times during development, thereby resetting their epigenome. Certain marks, however, appear to escape this reprogramming, which allows their transmission to the offspring and potentially guarantees transgenerational epigenetic inheritance. Here we discuss the molecular requirements for faithful transmission of epigenetic information and our current knowledge (...) about the transmission of epigenetic information through generations.

BackgroundRelatives have no formal position in the practice of euthanasia and physician-assisted suicide (EAS) according to Dutch legislation. However, research shows that physicians often involve relatives in EAS decision-making. It remains unclear why physicians do (not) want to involve relatives. Therefore, we examined how many physicians in the Netherlands involve relatives in EAS decision-making and explored reasons for (not) involving relatives and what involvement entails.MethodsIn a mixed-methods study, 746 physicians (33% response rate) completed a questionnaire, and 20 were interviewed. The (...) questionnaire included two statements on relatives’ involvement in EAS decision-making. Descriptive statistics were used, and multivariable logistic regression analyses to explore characteristics associated with involving relatives. In subsequent interviews, we explored physicians’ views on involving relatives in EAS decision-making. Interviews were thematically analysed.ResultsThe majority of physicians want to know relatives’ opinions about an EAS request (80%); a smaller group also takes these opinions into account in EAS decision-making (35%). Physicians who had ever received an explicit EAS request were more likely to want to know opinions and clinical specialists and elderly care physicians were more likely to take these opinions into account. In interviews, physicians mentioned several reasons for involving relatives: e.g. to give relatives space and help them in their acceptance, to tailor support, to be able to perform EAS in harmony, and to mediate in case of conflicting views. Furthermore, physicians explained that relatives’ opinions can influence the decision-making process but cannot be a decisive factor. If relatives oppose the EAS request, physicians find the process more difficult and try to mediate between patients and relatives by investigating relatives’ objections and providing appropriate information. Reasons for not taking relatives’ opinions into account include not wanting to undermine patient autonomy and protecting relatives from a potential burdensome decision.ConclusionsAlthough physicians know that relatives have no formal role, involving relatives in EAS decision-making is common practice in the Netherlands. Physicians consider this important as relatives need to continue with their lives and may need bereavement support. Additionally, physicians want to perform EAS in harmony with everyone involved. However, relatives’ opinions are not decisive. (shrink)

BackgroundInvolvement of adolescent girls in biomedical HIV research is essential to better understand efficacy and safety of new prevention interventions in this key population at high risk of HIV infection. However, there are many ethical issues to consider prior to engaging them in pivotal biomedical research. In Uganda, 16–17-year-old adolescents can access sexual and reproductive health services including for HIV or other sexually transmitted infections, contraception, and antenatal care without parental consent. In contrast, participation in HIV prevention research involving investigational (...) new drugs requires adolescents to have parental or guardian consent. Thus, privacy and confidentiality concerns may deter adolescent participation. We describe community perspectives on ethical considerations for involving adolescent girls in the MTN 034 study in Uganda.MethodsFrom August 2017 to March 2018, we held five stakeholder engagement meetings in preparation for the MTN 034 study in Kampala, Uganda (NCT03593655): two with 140 community representatives, two with 125 adolescents, and one with 50 adolescents and parents. Discussions were moderated by the study team. Proceedings were documented by notetakers. Summary notes described community perspectives of adolescent participation in HIV research including convergent, divergent or minority views, challenges, and proposed solutions.ResultsMost community members perceived parental or guardian consent as a principal barrier to study participation due to concerns about adolescent disclosure of pre-marital sex, which is a cultural taboo. Of 125 adolescent participants, 119 (95%) feared inadvertent disclosure of sexual activity to their parents. Community stakeholders identified the following critical considerations for ethical involvement of adolescents in HIV biomedical research: (1) involving key stakeholders in recruitment, (2) ensuring confidentiality of sensitive information about adolescent sexual activity, (3) informing adolescents about information to be disclosed to parents or guardians, (4) offering youth friendly services by appropriately trained staff, and (5) partnering with community youth organizations to maximize recruitment and retention.ConclusionsStakeholder engagement with diverse community representatives prior to conducting adolescent HIV prevention research is critical to collectively shaping the research agenda, successfully recruiting and retaining adolescents in HIV clinical trials and identifying practical strategies to ensure high ethical standards during trial implementation.

In February 2014, the Belgian Parliament passed legislation allowing euthanasia for terminally ill children of all ages by 86 votes to 44, with 12 abstentions. The Bill became law in early March after being signed by the King, making Belgium the first country in the world to abolish age restrictions for euthanasia. Previously, the youngest age at which euthanasia was permitted was 12 years old in The Netherlands.1Euthanasia was legalised in Belgium in 2002, and the new legislation introduces amendments to (...) the law extending euthanasia to minors in certain circumstances. Euthanasia is now permissible for children of all ages where the child has a “terminal and incurable illness”, experiences “constant and unbearable physical suffering”, and death is expected to occur within a “brief period”. The child must be deemed capable of making the decision, and have the agreement of their parents.Belgian law sets no timetable for euthanasia from the point at which the patient first expresses a wish to die. As with adults seeking euthanasia, any request must be made in writing. A physician and “outsider” brought in to give a second opinion must agree upon the diagnosis and prognosis, and a paediatric psychiatrist or psychologist must certify in writing that the child possesses “the capacity of discernment”. Following this, the child's physician must meet with the parents to inform them of the outcome of the consultation and ensure they are in agreement with the child's request. The child and the family must receive psychological care and support if so desired.The move provoked heated debate and divided the medical, legal and political professions in Belgium. A group of 160 of the country's paediatricians opposed a change in the law, citing concerns about the largely subjective assessment of the “capacity of discernment”, and drawing attention to advances in ….

Animal and plant species exhibit an astonishing diversity of sexual systems, including environmental and genetic determinants of sex, with the latter including genetic material in the mitochondrial genome. In several hermaphroditic plants for example, sex is determined by an interaction between mitochondrial cytoplasmic male sterility (CMS) genes and nuclear restorer genes. Specifically, CMS involves aberrant mitochondrial genes that prevent pollen development and specific nuclear genes that restore it, leading to a mixture of female (male‐sterile) and hermaphroditic individuals in the population (...) (gynodioecy). Such a mitochondrial‐nuclear sex determination system is thought to be rare outside plants. Here, we present one possible case of CMS in animals. We hypothesize that the only exception to the strict maternal mtDNA inheritance in animals, the doubly uniparental inheritance (DUI) system in bivalves, might have originated as a mitochondrial‐nuclear sex‐determination system. We document and explore similarities that exist between DUI and CMS, and we propose various ways to test our hypothesis. (shrink)

In June 2021, the BMA published its report on moral distress and moral injury in UK doctors.1 The report includes definitions of the terms ‘moral distress’ and ‘moral injury’ as well as a summary of how the concepts have developed over time. There is also an analysis of the BMA’s pan-profession survey of moral distress and moral injury of doctors in the UK, the first of its kind. The impact of COVID-19 and recommendations for tackling moral distress also feature. Many (...) may be unfamiliar with the concepts of ‘moral distress’ and ‘moral injury’. These terms are relatively new, and debate is ongoing in academic circles on the best way to understand them.2 Some use the terms interchangeably. The BMA defines moral distress as the psychological unease generated where professionals identify an ethically correct action to take but are constrained in their ability to take that action. Even without an understanding of the morally correct action, moral distress can arise from the sense of a moral transgression. More simply, it is the feeling of unease stemming from situations where institutionally required behaviour does not align with moral principles. This can be as a result of a lack of power or agency, or structural limitations, such as insufficient staff, resources, training or time. The individual suffering from moral distress need not be the one who has acted or failed to act; moral distress can be caused by witnessing moral transgressions by others. Moral injury can arise where sustained moral distress leads to impaired function or longer-term psychological harm. Moral injury can produce profound guilt and shame, and in some cases also a sense of betrayal, anger and profound ‘moral disorientation’. It has also been linked to severe mental health issues. There is increasing recognition across the UK of the problem …. (shrink)

Background: Funding organisations and research ethics committees should play a part in strengthening attention to gender equality in clinical research. In the research policy of European Union , funding measures have been taken to realise this, but such measures are lacking in the EU policy regarding RECs.Objective: To explore how RECs in Austria, Germany, Ireland, The Netherlands and Sweden deal with gender equality issues by asking two questions: Do existing procedures promote representation of women and gender expertise in the committee? (...) How are sex and gender issues dealt with in protocol evaluation?Methods: Two RECs were selected from each country. Data were obtained through interviews with key informants and content analysis of relevant documents .Results: All countries have rules to ensure the presence of women on RECs; gender expertise is not required. Drug study protocols are carefully evaluated, sometimes on a formal basis, as regards the inclusion of women of childbearing age. The reason for excluding either one of the sexes or including specific groups of women or making a gender-specific risk–benefit analysis are investigated by some RECs. Such measures are, however, neither defined in the regulations nor integrated in review tools.Conclusions: The RECs investigated in five European member states are found to pay limited attention to gender equality in their working methods and, in particular in protocol evaluation. Policy and regulations of EU are needed to strengthen attention to gender equality in the work of RECs. (shrink)

The British Medical Association has published a new report on health and human rights in immigration detention in the UK. Locked up, locked out outlines how aspects of current detention policies and practices are detrimental to the health of those detained and the challenges doctors face in providing healthcare in the immigration detention setting. It makes a number of recommendations aimed at addressing policy and practice which impact on health and well-being, including calling for an end to the routine use (...) of detention as a means of monitoring those facing removal from the UK and for the introduction of a time limit on the length of time individuals can be detained. It also provides guidance for doctors working in these settings on some of the common ethical and professional dilemmas they may face. The report can be accessed and downloaded at www.bma.org.uk/immigrationdetention. The Government has announced its intention to review mental health legislation for England and, in relation to non-devolved issues, for Wales.1 The Government states that it is ‘committed to delivering parity of esteem between mental and physical health’, although it does not clarify the meaning of ‘parity of esteem’. Similarly, the Government states that it wants to ensure that people with mental health problems ‘are treated with dignity, and that their liberty and autonomy is respected as far as possible’. Again, the Government has not indicated the meaning of ‘as far as possible’. Although not directly mentioned in the review’s terms of reference, it must be set against the background of changing legal and ethical expectations in relation to the rights of those with mental or cognitive disorders and disabilities. The UK is a signatory to the United Nations Convention on the Rights of People with …. (shrink)

Erdoğan intensifies assault on Turkish civil society Deeply worrying reports from the Turkish Medical Association suggest that the Turkish President Recep Erdoğan is hardening his attack on civil society in Turkey, using the legitimate activities of the TTB as the flimsiest of pretexts. In January 2018, the TTB issued a short statement raising concerns about the impact on public health of Turkey’s military operation in the Kurdish-controlled region of northern Syria. It denounced the operation saying ‘No to war, peace immediately’. (...) In response to the Association’s press release, the Turkish president publicly accused the 83 000 strong TTB of being terrorist sympathisers. ‘This institution has nothing to do with Turkishness and nothing about them is worthy of the notion of Turkishness’, he said. 1 Eleven of its senior doctors, including the Association’s chairman, were later detained following an order from a Turkish prosecutor. President Erdoğan made it... (shrink)

This paper serves two purposes: first, the proposition of an ethical fiduciary theory that substantiates the often-cited assertion that the patient–physician relationship is fiduciary in nature; and second, the application of this theory to the case of informed consent. Patients’ decision-making preferences vary significantly. While some seek fully autonomous decision-making, others prefer to delegate parts of their decision. Therefore, we propose an ethical fiduciary theory that allows physician and patient to jointly determine the physician’s role on a spectrum from fiduciary (...) as advisor to fiduciary as agent. Drawing on legal concepts of the fiduciary relationship and on phenomenological accounts of obligation by Lévinas and Løgstrup, our theory relies on the key attributes of trust, vulnerability and otherness. Finally, practical implications of this theory for the informed consent process are developed: we propose a preassessment of patients’ risk and value profiles as well as a restructuring of the oral consent interview and the written consent materials.

Doctors and medical students in the UK have voted in support of the decriminalisation of abortion for women who self-administer abortions and healthcare professionals who provide abortions within the context of their clinical practice. Abortion should be treated as a medical issue rather than a criminal one. ### Background to the vote The vote took place at the end of June during the British Medical Association’s Annual Representative Meeting, where representatives of doctors and medical students from across the British Isles (...) gathered to set BMA policy through democratic procedures. Representatives considered the issue of decriminalisation during a 2-hour debate, where diverse and opposing viewpoints were heard. The debate was informed by a neutral discussion paper that was published by the BMA in February, which provided a guide to some of the key legal and ethical issues raised by the debate around decriminalisation.1 The BMA’s new policy only relates to whether abortion should or should not be a criminal offence; the policy does not address the broader issue of when and how abortion should be available. The BMA has established policy on these issues which remains unchanged.2 ### The law on abortion Induced abortion is currently a crime throughout the British Isles. There are, however, a range of exceptions to the crime laid out in statute and/or common law, for example, in England, Scotland and Wales, under the Abortion Act 1967. Any healthcare professionals operating within those defined exceptions, which include grounds for authorising an abortion and procedural requirements, can lawfully carry out an abortion as a clinical procedure. Outside these defined exceptions, the criminal offences potentially apply both to those who participate in carrying out abortions for others, including doctors, nurses and midwives, and to women who carry out abortions on themselves. For example, healthcare professionals who do not follow procedural requirements can attract criminal sanctions …. (shrink)

Court of appeal ruling on assisted dyingIn July 2013, the Court of Appeal ruled on an assisted dying case brought by Paul Lamb, a 58-year-old man who has been quadriplegic and without function in any of his limbs, apart from a little movement in his right hand, since a car accident in 1990.1 Mr Lamb was permitted by the Court to take over the legal case of Tony Nicklinson, who died in August 2012, less than a week after his request (...) for judicial review was rejected by the High Court.2 Like Mr Nicklinson, the severity of Mr Lamb's injuries means that he is unable to take his own life, other than by starvation. He would like his life to be ended, preferably by lethal injection administered at home, and does not want to travel to Switzerland for an assisted suicide.Mr Lamb's case was heard, along with that of Mr Nicklinson's wife and that of another man, ‘Martin’, in the Court of Appeal in May.The Court identified three issues from the parties’ submissions: The common law should provide a defence to murder where that takes the form of euthanasia in circumstances where another party is giving effect to the settled wish of a competent person. The legal prohibitions on those providing assistance constitute a disproportionate interference with Article 8 rights to a private and family life. The Director of Public Prosecution's policy statement on factors which he will take into account when considering whether or not to exercise his discretion in favour of prosecuting does not satisfy the ….

Résumé Cet article se propose de questionner la lecture de l’espace russe par Fernand Braudel (1902-1985). Le rôle de Fernand Braudel dans l’invention des aires culturelles à la française et sa promotion des échanges Est-Ouest sont contextualisés par l’histoire du dialogue asymétrique et politisé entre historiens français et soviétiques. L’article montre que son analyse de l’économie-monde russe des 16e-18e siècles et de la civilisation russe a amené Braudel à proposer un décentrement original de l’analyse spatiale, loin du regard occidental traditionnellement (...) porté de l’Ouest vers l’Est.

Essex University, in association with Johns Hopkins Center for Public Health and Human Rights, has brought out a timely report highlighting the increasing global criminalisation of the provision of healthcare.1 The report, with a foreword by Professor Dainius Puras, United Nations Special Rapporteur on the right to health, explores the pressures on medical impartiality arising in large part from both global and national responses to the threat of terrorism. Both international humanitarian law, human rights law and long-established principles of medical (...) ethics—as set out in various declarations of the World Medical Association—establish an absolute principle that all people, regardless of their beliefs, affiliation or status, have rights of access to appropriate healthcare. And this right extends to wounded and sick combatants, as well as civilians, during times of armed conflict. One of the challenges in this area is that in recent years, many conflicts have become ‘asymmetric’. Contemporary conflicts seldom involve opposing state armies. Instead, they increasingly involve irregular combatants, often labelled ‘terrorists’ or ‘insurgents’ by the states they are opposing. In response to these threats, many states have developed sometimes draconian legislation outlawing terrorist groups and those offering support. The danger, outlined in some detail in the report, is that the vital distinction between the impartial provision of medical care and the criminal offence of materially aiding terrorism is lost. In 2016, largely in response to the deliberate targeting of healthcare personnel and facilities in the conflicts disfiguring the greater Middle …. (shrink)

ObjectiveFreezing of gait is detrimental to patients with idiopathic Parkinson’s disease. Its pathophysiology represents a multilevel failure of motor processing in the cortical, subcortical, and brainstem circuits, ultimately resulting in ineffective motor output of the spinal pattern generator. Electrophysiological studies pointed to abnormalities of oscillatory activity in freezers that covered a broad frequency range including the theta, alpha, and beta bands. We explored muscular frequency domain activity with respect to freezing, and used deep brain stimulation to modulate these rhythms thereby (...) evaluating the supraspinal contributions to spinal motor neuron activity.MethodsWe analyzed 9 PD freezers and 16 healthy controls. We studied the patients after overnight withdrawal of dopaminergic medication with stimulation off, stimulation of the subthalamic nucleus or the substantia nigra pars reticulate, respectively. Patients performed a walking paradigm passing a narrow obstacle. We analyzed the frequency-domain spectra of the tibialis anterior and gastrocnemius muscles in ‘regular gait’ and during the ‘freezing’ episodes.ResultsIn stimulation off, PD freezers showed increased muscle activity of the alpha and low-beta band compared to HC in both TA and GA. This activity increase was present during straight walking and during the freezes to similar extent. STN- but not SNr-DBS decreased this activity and paralleled the clinical improvement of freezing.ConclusionWe found increased muscle activation of the alpha and lower beta band in PD freezers compared to HC, and this was attenuated with STN-DBS. Future studies may use combined recordings of local field potentials, electroencephalography, and electromyography to interrogate the supraspinal circuit mechanisms of the pathological activation pattern of the spinal pattern generator.

Morality in Sport Sport continues to make its presence known throughout the world as it prospers at all levels. Amazingly, there is no end in sight to the popularity and growth of sport. Essential to sport's continued prosperity, growth, and overall livelihood is the sustenance of a firm moral base. It is the goal and hope of the author that you find this textbook to be a useful guide in helping you maintain and build upon the foundation of moral good (...) that is required for sport to exist now and in the future. The need to make good moral decisions in sport is constant. And, although opportunities to make such decisions in sport are seemingly endless, what is "moral" can be somewhat unclear. Given the various perspectives on morality and the lack of clear-cut distinctions between moral and immoral actions, disagreements regarding moral behavior and sport are likely to always exist. However, having a blatant disregard for good moral behavior in sport is difficult to defend from most any position. (shrink)

Functional imaging studies of neurologically intact adults have demonstrated that the right posterior cerebellum is activated during verb generation, semantic processing, sentence processing, and verbal fluency. Studies of patients with cerebellar damage converge to show that the cerebellum supports sentence processing and verbal fluency. However, to date there are no patient studies that investigated the specific importance of the right posterior cerebellum in language processing, because: case studies presented patients with lesions affecting the anterior cerebellum, and group studies combined patients (...) with lesions to different cerebellar regions, without specifically reporting the effects of right posterior cerebellar damage. Here we investigated whether damage to the right posterior cerebellum is critical for sentence processing and verbal fluency in four patients with focal stroke damage to different parts of the right posterior cerebellum. We examined detailed lesion location by going beyond common anatomical definitions of cerebellar anatomy, and employed a recently proposed functional parcellation of the cerebellum. All four patients experienced language difficulties that persisted for at least a month after stroke but three performed in the normal range within a year. In contrast, one patient with more damage to lobule IX than the other patients had profound long-lasting impairments in the comprehension and repetition of sentences, and the production of spoken sentences during picture description. Spoken and written word comprehension and visual recognition memory were also impaired, however, verbal fluency was within the normal range, together with object naming, visual perception and verbal short-term memory. This is the first study to show that focal damage to the right posterior cerebellum leads to language difficulties after stroke; and that processing impairments persisted in the case with most damage to lobule IX. We discuss these results in relation to current theories of cerebellar contribution to language processing. Overall, our study highlights the need for longitudinal studies of language function in patients with focal damage to different cerebellar regions, with functional imaging to understand the mechanisms that support recovery.

Theories of perception have traditionally dismissed the sense of smell as a notoriously variable and highly subjective sense, mainly because it does not easily fit into accounts of perception based on visual experience. So far, philosophical questions about the objects of olfactory perception have started by considering the nature of olfactory experience. However, there is no philosophically neutral or agreed conception of olfactory experience: it all depends on what one thinks odors are. We examine the existing philosophical methodology for addressing (...) our sense of smell: on the one hand appeals to phenomenology that focus on the experiential dimensions of odor perception and on the other approaches that look at odor sources and their material dimensions. We show that neither strategy provides enough information to account for the human sense of smell and argue that the inclusion of the missing dimension of biology, with its concern for the function (or functions) of olfaction, provides the means to develop a satisfactory and empirically informed philosophy of smell.
