Applying memories of reinforcement outcomes mainly to Pavlovian conditioning

A theory devised initially on the basis of instrumental reward schedule data, such as the PREE, was extended to deal with various Pavlovian findings. These Pavlovian findings include blocking, unblocking, relative validity, positive and negative patterning, renewal, reinstatement, reacquisition, and inhibition. In addition, the sequential model was discussed in relation to the rule-learning view of Hulse and Dorsky (1977) employing data from a report by Bloom and Capaldi (1961).     

Song recognition in zebra finches: Are there sensitive periods for song memorization?

Male zebra finches learn to sing songs that they hear between 25 and 65 days of age, the sensitive period for song learning. In this experiment, male and female zebra finches were exposed to zebra finch songs either before (n = 9) or during (n = 4) the sensitive period. Following song exposure, recognition memory for the songs was assessed with an operant discrimination between familiar and novel songs. Zebra finches that were exposed to songs between 22 and 30 days of age discriminated between familiar and novel songs; zebra finches exposed to songs from 9 to 17 days of age did not. Failure to memorize songs heard prior to the sensitive period may contribute to the exclusion of those songs from the repertoire of songbirds.     

A Recess Evaluation with the Players: Taking Steps Toward Participatory Action Research

This qualitative study, part of a Canadian national study of fathers’ involvement, opened up First Nations and Métis fathering as a new area of inquiry. Conversational interviews with 80 Indigenous fathers illuminated the socio-historical conditions that have shaped Indigenous men’s experiences of learning to be a father and becoming a man in the context of changing gender relationships and the regeneration of circles of care. Indigenous fathers’ experiences unfold in a socio-historical context fraught with difficulties. However, the study findings suggest cultural strengths and sources of resilience unseen in research and community programs driven by Euro-western perspectives. This research can inform efforts to reduce systemic barriers and reconstitute positive father involvement following disrupted intergenerational transmission of fathering in Canada and elsewhere.     

Implementation Quality and Positive Experiences in After-School Programs

Data collected during an evaluation of a multi-site trial of an enhanced after-school program were used to relate quality of program implementation to student experiences after school. The enhanced after-school program incorporated a drug use and violence prevention component that was shown to be effective in previous research. Building on Durlak and Dupre’s (Am J Community Psychol 41:327–350, 2008) dimensions of implementation, we assessed the level of dosage, quality of management and climate, participant responsiveness, and staffing quality achieved at the five program sites. We evaluated how these characteristics co-varied with self-reported positive experiences after-school. The study illustrates how multiple dimensions of program implementation can be measured, and shows that some but not all dimensions of implementation are related to the quality of student after-school experiences. Measures of quality of management and climate, participant responsiveness, and staffing stability were most clearly associated with youth experiences. The importance of measuring multiple dimensions of program implementation in intervention research is discussed.     

Covariation of self‐ and other‐directed aggression among inpatient youth: continuity in the transition to treatment and shared risk factors

Although other‐ and self‐directed aggression covary in very high‐risk youth, these forms of aggression infrequently are studied simultaneously. Understanding better their covariation is an important task for improving services to high‐risk youth. In this study, data from the clinical records of 476 youth admitted to secure inpatient treatment were analyzed to examine relations among self‐ and other‐directed aggression exhibit before and during inpatient treatment. Analyses tested the hypotheses that self‐ and other‐directed aggression would tend to covary and display continuity from pre‐treatment to in‐treatment. Also tested were the hypotheses that youth with histories of co‐occurring self‐ and other‐directed aggression would show the highest levels of aggression during treatment and the greatest degree of personal and contextual risk on entering treatment. These hypotheses were largely supported. Exploratory analyses revealed interesting discontinuities in aggression (aggression emitted only before or during treatment) with critical implications for research and practice with youth receiving clinical care, especially those in institutional placements.

生涯适应力的作用：个体与组织层的跨层面分析*

生涯适应力(career adaptability)是生涯建构理论提出的自我职业生涯管理的核心概念,但国外理论和实践一直认为生涯适应力是一把双刃剑(生涯适应力高的员工工作绩效高,但其离职意向也高),本研究将对此进行检验;同时,生涯适应力作为个体职业生涯开发的核心变量,它在组织职业生涯管理跨层面作用中的价值也未曾研究。通过员工在两个时间点自评和管理者他评问卷,获得54家单位的485份有效调查问卷。结构方程模型分析的结果表明,生涯适应力不仅与工作绩效有显著正相关,而且也与离职意向有显著负相关。层次回归分析结果表明,工龄是生涯适应力与离职意向、工作绩效关系的调节变量;也就是说,工龄短员工的生涯适应力与工作绩效呈显著正相关,与离职意向呈显著负相关,但工龄长员工的生涯适应力与二者的关系都不显著。基于跨层面研究设计,多层线性模型(HLM)分析的结果表明,生涯适应力是组织职业生涯管理与个体工作绩效之间的完全中介变量,但在组织职业生涯管理与离职意向之间的中介作用不显著。这不但回答了生涯适应力对组织价值的管理困境问题,也解决了组织职业生涯管理与个体工作绩效的连接纽带问题。     

Kierkegaard on the (un)happiness of faith

Hegel famously accuses Christianity of ‘unhappy consciousness’: it has a normative goal – union with the divine – that it cannot, in principle, satisfy. Kierkegaard was intimately aware of this criticism and, unlike some of Hegel’s other accusations, takes it seriously. In this paper my co-author and I investigate the way in which Kierkegaard addresses this issue in two texts published in 1843: Fear and Trembling and ‘The Expectancy of Faith’. We are especially interested in how the two texts describe faith’s relationship to finitude: for instance, whether the person of faith is permitted to expect that God will bless her in particular and concrete ways. My co-author and I offer competing interpretations. I argue that there is a deep tension in the way faith is described in the two texts; my co-author argues that there is consonance.     

On Luo Congyan’s Ethics

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense. On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the earlier Confucian thought. Translated from Studies in Ethics by Xiao Mo     

荀子社会分层的政治伦理思想及其现代价值

基于天人关系,荀子从人的自然本性和社会性出发,对其社会分层的政治伦理思想作了哲学论证。以“礼”为核心和标准,荀子把社会分层划分为社会等级分层与社会职业分层两个层面。荀子把“礼”的功能———“群”与“分”,特别是等级差别之“分”作为社会分层的手段,以最终实现社会和谐有序的政治理想。这对于我们今天构建社会主义和谐社会仍具有一定的现实意义。     

人与自然和谐的道德基础——古代"天人合一"思想的现代生态伦理启示

人与自然的和谐有着道德基础。古代的“天人合一”思想为我们从道德的视角研究人与自然的和谐,以及建构现代生态伦理观提供了一定的帮助。从道德的意义上,人与自然的和谐中人是道德主体,承担着全部道德责任,其行为是道德评价的对象。人对自然的适应与改造、尊重与利用是辩证的统一。
