Directed Altruistic Living Organ Donation: Partial but not Unfair

Arguments against directed altruistic living organ donation are too weak to justify a ban. Potential donors who want to specify the non-related person or group of persons to receive their donated kidney should be accepted. The arguments against, based on considerations of motivation, fairness and (non-)anonymity (e.g. those recently cited by an advisory report of the Dutch Health Council), are presented and discussed, as well as the Dutch Governments response. Whereas the Government argues that individuals have authority with regard to the allocation of their organs, partial considerations have not been sufficiently explored. In addition, it is argued that partial relationships govern human life, are significant and should be valued highly. These relationships are at the core of accepted living kidney donation between relatives (family members, partners, friends). Respecting the particular act of living donation goes beyond respect for autonomy; it touches upon our personal and social identity. Donation, e.g. of a kidney, is not undertaken strictly for the benefit of the recipient, but also to meet the moral standards we wish to set for ourselves. This consideration, rooted in a view of moral identity, provides the basis for many forms of directed donation that are both partial and justified. If the importance of this is not recognized, social policies can be neither adequate nor effective.     

The Ethics and Politics of Religious Ethics, 1973–2023

This essay addresses the questions, “what good is religious ethics for?” and “what justification exists for the field?” in three steps. First, it canvases how religious ethicists have offered reasons for carrying out work in the field to identify an Anti-Reductive Paradigm that is guided by an Egalitarian Imperative. That imperative functions as a thin, minimal morality of inclusivity and equal respect that guides work in the field. Second, the essay considers the field's ends. Here the focus shifts from values that shape the field's methods to values that can describe the field's purposes. That shift requires us to think in terms of a thick rather than a thin morality, one with substantive rather than procedural virtues in mind. The essay offers a constructive, substantive proposal under the rubric of Critical Humanism. Critical Humanism justifies the study of religious ethics as an enterprise that can expand the moral imagination through its encounter with difference. It is shaped by four values: post-critical reasoning, social criticism, cross-cultural fluency, and environmental responsibility. Third, the essay brings the two parts of the argument together by explaining how to connect such purposes to the thin morality of inclusivity and equal respect. One upshot of the essay is to have us think not only about values, but also about power as it pertains to scholarship in the guild; hence the attention to the ethics and politics of religious ethics.     

Evidence for a developmental shift in the motivation underlying helping in early childhood

We investigated children's positive emotions as an indicator of their underlying prosocial motivation. In Study 1, 2-, and 5-year-old children (N = 64) could either help an individual or watch as another person provided help. Following the helping event and using depth sensor imaging, we measured children's positive emotions through changes in postural elevation. For 2-year-olds, helping the individual and watching another person help was equally rewarding; 5-year-olds showed greater postural elevation after actively helping. In Study 2, 5-year-olds’ (N = 59) positive emotions following helping were greater when an audience was watching. Together, these results suggest that 2-year-old children have an intrinsic concern that individuals be helped whereas 5-year-old children have an additional, strategic motivation to improve their reputation by helping.     

内外动机对青少年记忆的影响及其神经机制

动机是一切行为的核心, 动机可分为外在和内在动机。青少年时期既是记忆的关键期, 也是动机发展的特殊时期。然而, 目前关于内外动机影响青少年记忆的研究才刚刚起步, 尚不清楚外在和内在动机影响青少年记忆的规律和机制是否一致, 也不清楚二者如何交互影响记忆。本研究将结合认知范式和脑成像技术, 考察外在和内在动机如何分别影响以及交互影响青少年记忆。这将有助于更加全面、深刻理解内外动机影响青少年记忆的独特规律和机制, 为科学提升青少年动机和记忆效果提供研究证据。     

Effects of phonological awareness and morphological awareness on blind students' reading comprehension

The exploration of blind students' reading skills is needed not only for further understanding their reading development but also for providing targeted suggestions for practical education. This study aims to examine the relations among phonological awareness (PA), homograph awareness (HA), compounding awareness (CA) and reading comprehension (RC), and explore the mediating effect of listening comprehension (LC) in Chinese blind students from elementary school. A total of 148 blind and 302 sighted elementary school students completed assessments of PA, HA, CA, LC and RC. The results found that PA, HA and CA were important variables that predicted Chinese blind and sighted students' RC not only directly but also indirectly through LC, which varied across different grades. The findings suggest that there were many similarities that exist in the influencing mechanism of RC between Chinese blind and sighted students.     

A functional analysis of personal autonomy: How restricting ‘what’, ‘when’ and ‘how’ affects experienced agency and goal motivation

Personal autonomy is central to people's experiences of agency and abilities to actively take part in society. To address the challenges of supporting autonomy, we propose a functional model of autonomy, according to which the experience of agency is a function of the opportunity to determine what to do, when to act and how to act in goal-pursuit. We tested the model in three experiments where the three goal-pursuit components could be constrained by another person or an artificial intelligence (AI) agent. Results showed that removing any of the three components from one's own decisions reduced experienced agency (Study 1a and 1b) and lowered motivation to pursue goals in organisational contexts (Study 2). In comparison to the strong and robust main effects, interactions between the components and the effects of the source of restriction (human vs. AI) were negligible. Implications for personal autonomy, algorithmic decision-making and behaviour change interventions are discussed.     

The effect of justified video game violence on aggressive behavior and moderated immersion: An experimental approach

The effect of violent video games on aggressive behavior is an important topic in the field of game research. Recently, growing evidence suggests that justified game violence decreases feelings of guilt caused by in-game immoral behavior. However, little is known about the impact on aggressive behavior, and whether other factors moderate this effect. In a two-factor experiment, we tested the impact of justification of video game violence on aggressive behavior, and whether this effect would be enhanced by game immersion. Pilot experiment 1 (N = 60) and pilot experiment 2 (N = 40) demonstrated that the justification of violence and game immersion was successfully controlled by avatar and graphics quality. In the Main experiment, 123 participants played one of four conditions of a video game (2 [justification: justified vs. unjustified violence] × 2 [immersion: high vs. low immersion]) and it was found that participants who played in the justified violence condition reported greater aggressive behavior than those in the unjustified violence condition. In addition, participants who played in high immersion reported greater aggressive behavior than those in low immersion. However, game immersion did not moderate the effects of justified violence. This unexpected effect is likely due to participants' distancing themselves from and identifying less with their violent avatars.     

Analysis of human body dynamics in simulated rear-end impacts

The objective of this study is to simulate the dynamic response of the human body within a rear-end impacted vehicle. A nonlinear mathematical model of a human body and a restraint system has been formulated. The model consists of connected rigid bodies representing the torso and limbs of the human frame. Nonlinear springs and dampers are used at the connection joints to represent human anatomical characteristics and limits imposed by muscles, ligaments, and soft tissue. Equations of motion are written for this model by using Kane's equation and multibody dynamics analysis procedures developed by Huston. The equations are integrated numerically for a number of specific cases where experimental data are available. Results show excellent agreement between the model and the experiments. The results of several accident simulations are also presented.
