Persistence during and resurgence following noncontingent reinforcement implemented with and without extinction

Noncontingent reinforcement (NCR) is typically implemented with extinction (EXT) for destructive behavior reinforced by social consequences and without EXT for destructive behavior reinforced by sensory consequences. Behavioral momentum theory (BMT) predicts that responding will be more persistent, and treatment relapse in the form of response resurgence more likely, when NCR is implemented without EXT due to the greater overall rate of reinforcement associated with this intervention. We used an analogue arrangement to test these predictions of BMT by comparing NCR implemented with and without EXT. For two of three participants, we observed more immediate reductions in responding during NCR without EXT. However, for all participants, NCR without EXT produced greater resurgence than NCR with EXT when we discontinued all reinforcers during an EXT Only phase, although there was variability in response patterns across and within participants. Implications for treatment of destructive behavior using NCR are discussed.     

Leadership behavior changes following a theory‐based leadership development intervention: A longitudinal study of subordinates’ and leaders’ evaluations

The aim was to evaluate effects of leadership courses based on the developmental leadership model at the leadership behavioral level. A longitudinal design was employed with assessments before, one and six months after the leadership courses. The sample consisted of 59 leaders who made self‐ratings and were rated by at least three subordinates on each occasion. Leadership behaviors were measured with the Developmental Leadership Questionnaire (DLQ). A limited increase of favorable leadership behaviors and a significant reduction of unfavorable leadership behaviors were found, particularly according to the subordinates’ ratings. A cluster analysis yielded three meaningful leader profiles and showed that this pattern was found in all three profiles, irrespective of how favorably they were rated before the onset of the intervention.     

Mill’s act-utilitarian interpreters on Utilitarianism chapter V paragraph 14

In the fourteenth paragraph of the fifth chapter of Utilitarianism, J. S. Mill writes that ‘We do not call anything wrong, unless we mean to imply that a person ought to be punished in some way or other for doing it; if not by law, by the opinion of his fellow-creatures; if not by opinion, by the reproaches of his own conscience.’ I criticize the attempts of three commentators who have recently presented act-utilitarian readings of Mill – Roger Crisp, David Brink, and Piers Norris Turner – to accommodate this passage.     

Diversity and Community: The Role of Agent‐Based Modeling

Community psychology involves several dialectics between potentially opposing ideals, such as theory and practice, rights and needs, and respect for human diversity and sense of community. Some recent papers in the American Journal of Community Psychology have examined the diversity‐community dialectic, some with the aid of agent‐based modeling and concepts from network science. This paper further elucidates these concepts and suggests that research in community psychology can benefit from a useful dialectic between agent‐based modeling and the real‐world concerns of community psychology.     

Ethical Challenges of Personal Disclosure in Gaining Entry with Religious Congregations

This is a story about learning how to navigate my social identities as a non‐religious gay man attempting to conduct data‐based consultation with a religious congregation. Beyond my own growth in knowing myself better, this story speaks to the larger ethical challenge of how we build trust in community relationships, and in particular how much of our personal selves we need to disclose in the process of an individual or group deciding to work with us. Individuals and groups make decisions to work with us based on who they perceive us to be; thus, what is our ethical obligation to disclose aspects of who we are to promote full informed consent? To illustrate this ethical challenge of personal disclosure, I tell the story of discussions I had with three different religious leaders and a congregational committee about potentially working together. Throughout these stories, I reflect on my own messy process of growth as a window into the more general question of how we navigate our identities and values as community psychologists in the work we do with communities.     

肝移植的伦理学问题

肝脏移植和其它器官移植一起实现了人类长期以来渴望生命再生的梦想,并成为终末期肝病的有效治疗方法。器官移植也面对许多伦理道德方面的难题。供体,特别是活体器官的摘取,受体的选择等,都受到社会道德观的制约。从伦理道德角度来分析如何制定相关的法律法规,成为当前社会关注的热点。从受体的利益、人体科研的道德规范以及相关制度的伦理学要求等方面,较为详细的阐述肝移植伦理学的基本原则。     

Toward an International Rule of Law: Distinguishing International Law-Breakers from Would-Be Law-Makers

An interesting fact about customary international law is that the only way you can propose an amendment to it is by breaking it. How can that be differentiated from plain law-breaking? What moral standards might apply to that sort of international conduct? I propose we use ones analogous to the ordinary standards for distinguishing civil disobedients from ordinary law-breakers: would-be law-makers, like civil disobedients, must break the law openly; they must accept the legal consequences of doing so; and they must be prepared to have the same rules applied to them as everyone else.
