Families play an essential role in deceased organ procurement. As the person cannot directly communicate his or her wishes regarding donation, the family is often the only source of information regarding consent or refusal. We provide a systematic description and analysis of the different roles the family can play, and actions the family can take, in the organ procurement process across different jurisdictions and consent systems. First, families can inform or update healthcare professionals about a person’s donation wishes. Second, families (...) can authorize organ procurement in the absence of deceased’s preferences and the default is not to remove organs, and oppose donation where there is no evidence of preference but the default is to presume consent; in both cases, the decision could be based on their own wishes or what they think the deceased would have wanted. Finally, families can overrule the known wishes of the deceased, which can mean preventing donation, or permitting donation when the deceased refused it. We propose a schema of 4 levels on which to map these possible family roles: no role, witness, surrogate, and full decisional authority. We conclude by mapping different jurisdictions onto this schema to provide a more comprehensive understanding of the consent system for organ donation and some important nuances about the role of families. This classificatory model aims to account for the majority of the world’s consent systems. It provides conceptual and methodological guidance that can be useful to researchers, professionals, and policymakers involved in organ procurement. (shrink)

Several studies have explored differences between North American and European doctor patient relationships. They have focused primarily on differences in philosophical traditions and historic and socioeconomic factors between these two regions that might lead to differences in behaviour, as well as divergent concepts in and justifications of medical practice. However, few empirical intercultural studies have been carried out to identify in practice these cultural differences. This lack of standard comparative empirical studies led us to compare differences between France and the (...) USA regarding end-of-life decision-making. We tested certain assertions put forward by bioethicists concerning the impact of culture on the acceptance of advance directives in such decisions. In particular, we compared North American and French intensive care professional's attitudes toward: (1) advance directives, and (2) the role of the family in decisions to withhold or withdraw life-support.

Despite continuing controversies regarding the vital status of both brain-dead donors and individuals who undergo donation after circulatory death (DCD), respecting the dead donor rule (DDR) remains the standard moral framework for organ procurement. The DDR increases organ supply without jeopardizing trust in transplantation systems, reassuring society that donors will not experience harm during organ procurement. While the assumption that individuals cannot be harmed once they are dead is reasonable in the case of brain-dead protocols, we argue that the DDR (...) is not an acceptable strategy to protect donors from harm in DCD protocols. We propose a threefold alternative to justify organ procurement practices: (1) ensuring that donors are sufficiently protected from harm; (2) ensuring that they are respected through informed consent; and (3) ensuring that society is fully informed of the inherently debatable nature of any criterion to declare death.

This study examined health professionals’ (HPs) experience, beliefs and attitudes towards brain death (BD) and two types of donation after circulatory death (DCD)—controlled and uncontrolled DCD. Five hundred and eighty-seven HPs likely to be involved in the process of organ procurement were interviewed in 14 hospitals with transplant programs in France, Spain and the US. Three potential donation scenarios—BD, uncontrolled DCD and controlled DCD—were presented to study subjects during individual face-to-face interviews. Our study has two main findings: (1) In the (...) context of organ procurement, HPs believe that BD is a more reliable standard for determining death than circulatory death, and (2) While the vast majority of HPs consider it morally acceptable to retrieve organs from brain-dead donors, retrieving organs from DCD patients is much more controversial. We offer the following possible explanations. DCD introduces new conditions that deviate from standard medical practice, allow procurement of organs when donors’ loss of circulatory function could be reversed, and raises questions about “death” as a unified concept. Our results suggest that, for many HPs, these concerns seem related in part to the fact that a rigorous brain examination is neither clinically performed nor legally required in DCD. Their discomfort could also come from a belief that irreversible loss of circulatory function has not been adequately demonstrated. If DCD protocols are to achieve their full potential for increasing organ supply, the sources of HPs’ discomfort must be further identified and addressed. (shrink)

Introduction: The Binge Eating Scale (BES) is a widely-used self-report questionnaire to identify compulsive eaters. However, research on the dimensions and psychometric properties of the BES is limited. Objective: The aim of this study was to examine the properties of the Spanish version of the BES. Method: Confirmatory Factor Analyses (CFAs) were carried out to verify the BES factor structure in a sample of Spanish college students (N = 428, 75.7% women; age range = 18–30). An invariance measurement routine was (...) carried out across sexes, the latent means were compared, and estimates of reliability and convergent and discriminant validity were presented. Results: A one-factor model fit the data best and was also equivalent between sexes. The scalar invariance model showed statistically significant differences across sexes, with a higher prevalence in women. Regarding reliability, the results were excellent. Finally, high statistically significant correlations were obtained with other measures of binge eating (BE), food addiction, impulsivity, binge drinking, and body mass index (BMI). Conclusions: The Spanish 16-item BES is a valid and reliable scale to evaluate BE in the youth population. (shrink)

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation World Championships held in Kazan, Budapest, and Gwangju. The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results,1 including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers were (...) located primarily in the first or second positions of the freestyle relay. The most successful gender strategy for the 4 × 100 m freestyle and for the 4 × 100 m medley relays was the order male-male-female-female, although no statistical differences were found for the medley relays. In the 4 × 100 m freestyle, the second and third relay legs had a statistical effect on the total relay time, whereas in the 4 × 100 m medley, all four relay legs had a statistical effect on the final performance, the weight of the four strokes being different in heats with respect to the final round. Also, a later position of the first female swimmer or the consecutive position of two female swimmers in the team order significantly affected the relay performance in specific events. Mixed relay events appeared to present specific strategies in comparison to traditional male- or female-only relay lineups. (shrink)

After compulsory secondary education; many teenagers face the process of choosing a university degree. This process involves uncertainties referred to their personal abilities, interests, social expectations and professional future. The present work is aimed at determining whether the reasons behind the selection of a particular university degree differ depending on the chosen degree. Another objective is determining whether these reasons differ significantly according to gender. The sample comprises 983 students belonging to the area of social and legal sciences at the (...) University of Seville. The obtained results reveal the existence of four main reasons behind the selection of university degrees for which significant gender-related differences were observed: easy degree, job opportunities, high wages and provision of social services. Besides, these seven reasons are observed to differ widely in six of the considered degrees. (shrink)

Several studies have examined victim blaming in rape scenarios. However, there is limited research on the analysis of the perception of blame when two or more perpetrators are involved. The present article explores the perception of blame in cases involving rape based on the level of resistance shown by the victim and the presence of one or more perpetrators. A study was carried out involving 351 university students who responded to a survey after reading a hypothetical assault scenario. Six situations (...) were established where the victim showed either low or high resistance, depending on whether the resistance was verbal or physical and verbal, and in the presence of one or two male perpetrators. It is expected that perpetrators are more culpable when acting in groups and that less resistance from the victim leads to greater attribution of blame. The results confirm that more blame is attributed to the perpetrators when they act in groups than when they act alone. Likewise, women consider the victim generally exerts greater resistance and this variable influences the attribution of greater blame. (shrink)

The objective of this research is to develop accurate forecasting models for chlorophyll-α concentrations at various depths in El Mar Menor, Spain. Chlorophyll-α plays a crucial role in assessing eutrophication in this vulnerable ecosystem. To achieve this objective, various deep learning forecasting techniques, including long short-term memory, bidirectional long short-term memory and gated recurrent uni networks, were utilized. The models were designed to forecast the chlorophyll-α levels with a 2-week prediction horizon. To enhance the models’ accuracy, a sliding window method (...) combined with a blocked cross-validation procedure for time series was also applied to these techniques. Two input strategies were also tested in this approach: using only chlorophyll-α time series and incorporating exogenous variables. The proposed approach significantly improved the accuracy of the predictive models, no matter the forecasting technique employed. Results were remarkable, with |$\overline{\sigma}$| values reaching approximately 0.90 for the 0.5-m depth level and 0.80 for deeper levels. The proposed forecasting models and methodologies have great potential for predicting eutrophication episodes and acting as decision-making tools for environmental agencies. Accurate prediction of eutrophication episodes through these models could allow for proactive measures to be implemented, resulting in improved environmental management and the preservation of the ecosystem.

Since 1968, the irreversible loss of functioning of the whole brain, called brain death, is assimilated to individual’s death. The almost universal acceptance of this neurological criterion of death had decisive consequences for the contemporary medicine, such as the withdrawal of mechanical ventilation in these patients and organ retrieval for transplantation. The new criterion was successfully accepted in part because the assimilation of brain death state to death was presented by medicine --and acritically assumed by most of societies-- as a (...) scientific and objective fact. Nevertheless, many people do not think that the patients suffering brain death are actually dead. We show here that those people are not necessarily wrong. It can be argued that, in fact, the justification of the neurological criterion is not scientific but moral. We outline the thesis that the problem surrounding the vital status of brain dead patients is due to a confusion between factual and normative questions. Furthermore, we claim that the donation of organs and the withdrawal of life-support could be ethically acceptable even if the patients suffering brain death are considered as alive. As an alternative to the dead donor rule, we propose a justification for organ donation of brain-dead patients based on the (moral) concepts of harm and consent : what truly justifies the procurement of organs on those patients is not that they are dead, but that they wish to donate their organs and that, since they have irreversibly lost their brain, they cannot be harmed.

The ever‐increasing demand for organs led Spain, France, and other European countries to promote uncontrolled donation after circulatory determination of death (uDCDD). For the same reason, New York City has recently developed its own uDCDD protocol, which differs from European programs in some key ways. The New York protocol incorporates a series of technical and management improvements that address some practical problems identified in response to European uDCDD protocols. However, the more fundamental issue of whether uDCDD donors are dead when (...) organs are procured remains problematic for the New York City protocol and, indeed, for all uDCDD protocols. In the United States, two amendments to the legal criteria of death have been suggested to avoid a formal violation of the dead donor rule in DCDD protocols: first, replacing the requirement “irreversible” with the weaker term “permanent,” and second, using the term “circulatory” instead of “cardiac” to identify the key function that must be lost to declare death. While intended to facilitate controlled DCDD, these modifications create a problem for uDCDD protocols: if extracorporeal membrane oxygenation is introduced to preserve the organs, then circulation is restored after death is declared. In this issue of the Hastings Center Report, Kevin Munjal and colleagues call for a new ethical construct and policy so that uncontrolled and controlled DCDD can coexist. (shrink)

Bioethicists involved in end‐of‐life debates routinely distinguish between ‘killing’ and ‘letting die’. Meanwhile, previous work in cognitive science has revealed that when people characterize behaviour as either actively ‘doing’ or passively ‘allowing’, they do so not purely on descriptive grounds, but also as a function of the behaviour’s perceived morality. In the present report, we extend this line of research by examining how medical students and professionals (N = 184) and laypeople (N = 122) describe physicians’ behaviour in end‐of‐life scenarios. (...) We show that the distinction between ‘ending’ a patient’s life and ‘allowing’ it to end arises from morally motivated causal selection. That is, when a patient wishes to die, her illness is treated as the cause of death and the doctor is seen as merely allowing her life to end. In contrast, when a patient does not wish to die, the doctor’s behaviour is treated as the cause of death and, consequently, the doctor is described as ending the patient’s life. This effect emerged regardless of whether the doctor’s behaviour was omissive (as in withholding treatment) or commissive (as in applying a lethal injection). In other words, patient consent shapes causal selection in end‐of‐life situations, and in turn determines whether physicians are seen as ‘killing’ patients, or merely as ‘enabling’ their death.

Since the 1960s, scientists, engineers, and healthcare professionals have developed brain–computer interface (BCI) technologies, connecting the user’s brain activity to communication or motor devices. This new technology has also captured the imagination of publics, industry, and ethicists. Academic ethics has highlighted the ethical challenges of BCIs, although these conclusions often rely on speculative or conceptual methods rather than empirical evidence or public engagement. From a social science or empirical ethics perspective, this tendency could be considered problematic and even technocratic because (...) of its disconnect from publics. In response, our trinational survey (Germany, Canada, and Spain) reports public attitudes toward BCIs (N = 1,403) on ethical issues that were carefully derived from academic ethics literature. The results show moderately high levels of concern toward agent-related issues (e.g., changing the user’s self) and consequence-related issues (e.g., new forms of hacking). Both facets of concern were higher among respondents who reported as female or as religious, while education, age, own and peer disability, and country of residence were associated with either agent-related or consequence-related concerns. These findings provide a first look at BCI attitudes across three national contexts, suggesting that the language and content of academic BCI ethics may resonate with some publics and their values.

Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...) Austria (AT), Belgium (BE), Denmark (DK), Germany (DE), Greece (GR), Slovenia (SI) and Spain (ES), asking participants about their donation preferences, as well as their beliefs and views about the policy in place. From these measures, we computed indices of informedness, policy support, and fulfilment of unexpressed preferences, which we compared across countries and consent systems. -/- Results Our study introduces a tool for analyzing policy governance in the context of OP. Wide variation in policy awareness was observed: Most respondents in DK, DE, AT and BE correctly identified the policy in place, while those in SI, GR and ES did not. Respondents in opt-out countries (AT, BE, ES and GR) tended to support the policy in place (with one exception, i.e., SI), whereas those in opt-in countries (DE and DK) overwhelmingly opposed it. These results reveal stark differences in governance quality across countries and consent policies: We found a preponderance of informed opposition in opt-in countries and a general tendency towards support–either informed or uninformed–in opt-out countries. We also found informed divergence in opt-in countries and a tendency for convergence–either informed or uninformed–among opt-out countries. -/- Conclusion Our study offers a novel tool for analyzing governance quality and illustrates, in the context of OP, how the strengths and weaknesses of different policy implementations can be estimated and compared using quantitative survey data.

Two main types of philosophical arguments have been given in support of the claim that the citizens of affluent societies have stringent moral duties to aid the global poor: “positive duty” arguments based on the notion of beneficence and “negative duty” arguments based on noninterference. Peter Singer’s positive duty argument (Singer 1972) and Thomas Pogge’s negative duty argument (Pogge 2002) are among the most prominent examples. Philosophers have made speculative claims about the relative effectiveness of these arguments in promoting attitudes (...) and behaviors that could lead to the alleviation of poverty. In this article we present the results of two empirical studies that evaluate these claims, and suggest that both arguments have a modest effect on people’s attitudes and behaviors regarding global poverty. In a replication of the second study, the negative duty argument, in particular, had a statistically significant effect on donations. We discuss the theoretical and practical significance of these results and suggest directions for further research on the role that philosophical arguments can play in engendering concern and action on pressing moral problems.

In this issue of the Report, James L. Bernat proposes an innovative and sophisticated distinction to justify the introduction of permanent cessation as a valid substitute standard for irreversible cessation in death determination. He differentiates two approaches to conceptualizing and determining death: the biological concept and the prevailing medical practice standard. While irreversibility is required by the biological concept, the weaker criterion of permanence, he claims, has always sufficed in the accepted standard medical practice to declare death. Bernat argues that (...) the medical practice standard may be acceptable on the ground that proving circulatory or brain permanence is sufficient to assure complete accuracy for death diagnosis. -/- The topic requires public deliberation: processes to survey people's opinions and mechanisms to channel their opinions into policy-making. What is at stake is the nature of our society. Do we want an expertocracy, in which an enlightened few design policies for the greater good of the majority and exploit the lack of public knowledge to achieve compliance? (shrink)

Since the 1960s, organ procurement policies have relied on the boundary of death—advertised as though it were a factual, value‐free, and unobjectionable event—to foster organ donation while minimizing controversy. Death determination, however, involves both discoveries of facts and events and decisions about their meaning (whether the facts and events are relevant to establish a vital status), the latter being subjected to legitimate disagreements requiring deliberation. By revisiting the historical origin of the dead donor rule, including some events that took place (...) in France prior to the report by the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death, I want to recall that those who first promoted the DDR did not take into account any scientific rationale to support the new proposed criteria to determine death. Rather, through a process of factual re‐semantization, they authorized themselves to decide about the meaning of death in order to implicitly prioritize the interests of organ recipients over those of dying people.

Alireza Bagheri supports a policy on organ procurement where individuals could choose their own definition of death between two or more socially accepted alternatives. First, we claim that such a policy, without any criterion to distinguish accepted from acceptable definitions, easily leads to the slippery slope that Bagheri tries to avoid. Second, we suggest that a public discussion about the circumstances under which the dead donor rule could be violated is more productive of social trust than constantly moving the line (...) between life and death.

Background: Several countries have recently changed their model of consent for organ donation from opt-in to opt-out. We undertook a systematic review to determine public knowledge and attitudes towards these models in Europe. Methods: Six databases were explored between 1 January 2008 and 15 December 2017. We selected empirical studies addressing either knowledge or attitudes towards the systems of consent for deceased organ donation by lay people in Europe, including students. Study selection, data extraction, and quality assessment were conducted by (...) two or more reviewers independently. Findings: Awareness of the consent model was lower in opt-out countries than in opt-in countries. A majority of the public agrees with opt-in, regardless of the law in their own country. There are ambivalent attitudes regarding the opt-out system. The public tend to prefer opt-in and mandatory choice over opt-out when several options are offered. Interpretation: The assumption that people in opt-out countries are aware of the legal requirements to be excluded from the pool of potential donors is not supported by the results of this review. This is a concern, since ignorance hinders people's autonomy regarding organ donation decision-making. Higher awareness of consent model in opt-in countries may reflect greater efforts to inform the public through campaigns to motivate donation. Legal moves towards opt-out are at odds with people's expressed preferences. Main limitations of this review are the lack of data from some countries, study population heterogeneity, and methodological shortcomings. (shrink)

This paper analyses the arguments for and against what we have called automatic organ procurement model in relation to the organs of the deceased. For this purpose, this work provides empirical evidence to assess the potential impact of this model on donation rates and on public opinion. Specifically, we examine first the reasons supporting this model, with special reference to utilitarian and justice arguments. On the other hand, we analyse both the approaches based on the violation of pre mortem and (...) post mortem interests opposing this theoretical model and the rejection the model would generate in the population. Finally, we point out the aspects that, in our opinion, should be exhaustively regulated if this model were implemented. In particular, we refer to the legal status of the human body, the treatments for end-of-life patients, the incentives for health professionals and the recognition of the right to conscientious objection.
