The assumed effects of positive feedback paired with success on motivation to do a task: The cases of characters with high and low initial levels of interest

This study investigated the effects of positive feedback paired with success on motivation to do a task, and examined whether this differed according to whether the person performing the task had a high or low initial level of interest in that task. Subjects (448 junior college students) were asked to rate (from 0–10) the level of motivation of characters in four different stories. Subjects believed that positive feedback would encourage the character to do a task regardless of initial level of interest. However, when positive feedback could not be expected, ratings for motivation fell. Ratings for motivation were further analyzed when no positive feedback could be expected, either after an earlier experience of positive feedback paired with success or after success only (no feedback). In the case of a low initial level of interest, it was assumed that motivation would be increased after positive feedback, but in the case of a high initial level of interest motivation was assumed to be decreased by an earlier experience of positive feedback paired with success. These results suggest that the effect of positive feedback paired with success will differ according to the level of a person's initial interest.     

项目反应理论框架下的新等值方法——对数对比等值法

项目反应理论有一些以除法形式给出的多级评分模型,若采用Haebara等值法、Stocking_Lord等值法或对称相对熵等值法进行测验等值,都因其对初值有较高要求而可能导致失败。针对这一类模型,我们给出了一种新的等值方法——对数对比等值法。这种方法收敛快,对迭代初值要求低,所得结果精度较高,可以为其他等值方法提供良好的初值。研究表明,对数对比等值法还改进和推广了0-1评分的两参数Logistic模型的Logit变换等值法

Commands as Divine Attributes

Theories of ethics that attempt to incorporate divine speech or commands as necessary elements in the construction of moral obligations are often viewed as vulnerable to a challenge based on the so‐called Euthyphro dilemma. According to this challenge, opponents of theistic ethics suppose that divine speech either informs one of a preexisting set of values and obligations, which makes it inconsequential, or is entirely arbitrary, which makes it irrational. This essay analyzes some of the debates on the nature of divine commands in eleventh‐century works of Islamic jurisprudence (u?ūl al‐fiqh). I show that Mu?tazilī jurisprudents advanced the view that divine commands were actions performed in time that had concrete manifestations, while Ash?arīs argued that divine speech in general, and commands in particular, were eternal divine attributes. After exposing certain weaknesses in the Euthyphro‐inspired objections to theistic ethics, I argue that the Ash?arī idea of commands as divine attributes is a promising move for scholars interested in defending a divine command view of moral obligation.     

When God Smites: Talking with Students about the Violence of God in Scripture

This article emphasizes the need for religious educators to address the issue of divine violence in Scripture with students, and it offers various pedagogical strategies for doing so. The focus is on violent Old Testament texts, with special attention given to the issue of Canaanite genocide. A general framework for structuring class time around divine violence in Scripture is proposed which includes (1) encouraging students to encounter violent biblical texts firsthand, (2) helping them understand why people find these passages problematic, and (3) offering various options for dealing with the potential problems these passages raise. In the second half of the article, significant attention is devoted to a number of practical considerations that should be taken into account when talking about this sensitive issue in class. A brief word about assessment is offered at the end.     

Sola Gratia as Divine Attribute: Resurrecting the God of the Gospel

Can we speak of sola gratia as a divine attribute so as to affirm that all that God does is grace? Traditionally, Western Christian theology has answered that question negatively, placing God's justice in opposition with God's grace and presenting a God whose love does not seem to be unconditional. This has been especially evident in the ways in which Scripture, the work of Christ, justification by faith, and the distinction between law and gospel commonly have been interpreted. By rethinking those traditional interpretations on the basis of an understanding of divine grace as unconditional love, we can indeed proclaim a God of sola gratia and a gospel capable of transforming human lives and responding effectively to the crisis of faith we face today.     

Delving into the ‘emotional storms’: A thematic analysis of psychoanalysts’ initial consultation reports

Psychoanalysts’ written reports on initial consultations are a window into the complexities of a crucial aspect of psychoanalytic work. However, systematic research in this area has largely focused on patients’ demographic factors or standardized measures. The present study looked at reports of all the consultations taking place at the London Clinic of Psychoanalysis over one calendar year (N = 100). The aim was to explore psychoanalysts’ different explicit styles of working and reporting as well as further understanding implicit processes used in thinking and writing about each particular consultation experience. A thematic analysis revealed a set of themes that related to a style of working and thinking about the consultation process as a dyadic experience, where the interaction, affective reactions and contact made between the two are the focus when thinking of making a recommendation for psychoanalysis. The majority of the reports had an open, exploratory quality. The writing of reports appears to give the analyst an opportunity to process the consultation experience and arrive at a more triangular position. Writing reports is a more valuable part of the consultation process than has formally been recognized and acknowledged. The limitations of this study as well as the relevance of these findings for future research are discussed.     

Initial responses to the first dose of nicotine in novel smokers: The role of exposure to environmental smoking and genetic predisposition

Background: Sensitivity to initial smoking constitutes an early predictor of the risk of dependence. We investigated the role of exposure to smoking (by parents, siblings, and peers) and reward-related candidate gene polymorphisms (OPRM1 A118G, DRD2 TaqlA and DRD4?bp VNTR) in adolescents’ responses to initial smoking.

Methods: We used cross-sectional survey data and saliva samples from 171 Dutch students who had never inhaled on a cigarette (mean age: 13.9?years). The outcome measure was adolescents’ self-reported responses to initial smoking.

Results: Exposure to peer smoking was associated with increased liking (OR?=?1.74, CI?=?1.13–2.70) and more pleasant sensations (β?=?.21, p?=?.01). Exposure to maternal smoking was associated with less unpleasant sensations (β?=??.20, p?=?.01). Adolescents carrying the G-variant of the OPRM1 A118G polymorphism were more likely to report liking (OR?=?2.50, CI?=?1.09–5.73) and adolescents homozygous for the C-variant of the DRD2 TaqlA polymorphism reported less unpleasant sensations (β?=?.18, p?=?.04).

Conclusion: Although preliminary, these findings suggest that exposure to environmental smoking and polymorphisms in the OPRM1 and DRD2 gene may affect initial sensitivity to nicotine, an early phenotype of the risk of dependence. In the future, collaborative efforts to combine data from multiple studies in meta-analyses are needed to improve accuracy of estimated effects in genetic studies.     

An analytic solution of initial boundary value problem for 3D quasicrystals in half space

In this article, initial boundary value problem for 3D quasicrystals in half space is considered. An analytic method is proposed for special form of initial conditions and nonhomogeneous term. It is explained that a weak solution of the problem can be constructed in the similar form of data by using symbolic calculations.
