Drug addicts in therapy—changes in life space in the course of one year

In a residential community treatment setting, moods and emotional states of drug addicts were explored over a 1‐year period. The specific form of treatment of heroin addiction employed in the communities is based on the importance of interpersonal relationships for psychosocial transition. Twenty‐nine participants reported current mood, emotions, attributions, and motive activation using a time‐sampling diary for 2 weeks at the beginning of the treatment, and 6 and 12 months later. Results show an increase in positive emotions, and in subjective strength and freedom. Furthermore, participants report higher self‐esteem and use less fatalistic attributions. This is interpreted as indicating successful transition processes in terms of higher autonomy, a more extended life space and increased levels of realism.

A transition of Chinese humanism and aesthetics from rationalism to irrationalism

Chinese people attach importance to intuition and imagery in ways of thinking that are quite sensible, but the result, i.e. the thoughts that are popularized in virtue of political power, are rather rational. These rational thoughts, which were influenced by Buddhism and continually became introspective, had been growing more irrational factors. Up to the middle and late Ming Dynasty, when the economy was developed, they merged with the growing emphasis on daily needs of food and clothes and the envisagement to the utilitarian circumstances, and finally broke through the threshold of rationalism. Under the attack of Geng Dingxiang, Li Zhi who emphasized these thoughts was forced beyond his previous boundaries and led a whole variation in how he viewed a series of issues including values, humanity, ethics and aesthetics. This indicated a historical change from rationalism to irrationalism in Chinese humanism and aesthetics thoughts.

The Role of the Quality of College‐Based Relationship on Social Media in College‐to‐Work Transition of Korean College Students: The Longitudinal Examination of Intimacy on Social Media,Social Capital,and Loneliness

This study investigated the mediation effects of social capital on the associations between the quality of relationship, intimacy in particular, with college friends on social media and loneliness during college‐to‐work transition of Korean college students. Longitudinal data were collected from three surveys with a 6‐month interval. The first wave of the survey was completed by 521 participants; 110 graduates participated in the second wave, and 175 in the third wave. Latent growth modeling analysis revealed that the linear growth function produced a better fit than the no‐growth models for intimacy on social media, social capital, and loneliness. While intimacy on social media and bonding capital increased during the three‐time interval, bridging capital and loneliness decreased. In addition, the slope of intimacy on social media was positively related to the slopes of bridging and bonding capital, both of which, in turn, had a negative association with the slope of loneliness. These findings indicate the beneficial role of the quality of relationship on social media in college‐to‐work transition.     

Young people's perceptions and experiences of leaving high school early: an exploration

Research suggests it is important for students to feel a sense of belonging to their school. Students who do not belong at school often attempt to satisfy this need through membership in antisocial groups, or they drop out from school altogether. The current study explored the perceptions and experiences of the school context held by young people who have left school early. Twelve young people aged 16–19 years were interviewed on their experiences of school and their wellbeing as a result of leaving school early. Constructionist grounded theory methodology formed the basis of the data analysis. The early leaving process was identified as having three phases; exclusion from school, the transition into workforce and the ‘now’ phase. The results identified factors in the school context that contributed to early student withdrawal. Furthermore, the research has implications for creating a ‘normative narrative’ (Rappaport, 2000 ) in relation to early school leavers. Copyright © 2007 John Wiley & Sons, Ltd.     

The effect of aging in recollective experience: the processing speed and executive functioning hypothesis

This study was designed to investigate the effects of aging on consciousness in recognition memory, using the Remember/Know/Guess procedure (Gardiner, J. M., & Richarson-Klavehn, A. (2000). Remembering and Knowing. In E. Tulving & F. I. M. Craik (Eds.), The Oxford Handbook of Memory. Oxford University Press.). In recognition memory, older participants report fewer occasions on which recognition is accompanied by recollection of the original encoding context. Two main hypotheses were tested: the speed mediation hypothesis (Salthouse, T. A. (1996). The processing-speed theory of adult age differences in cognition. Psychological Review, 3, 403–428) and the executive-aging hypothesis (West, R. L. (1996). An application of prefrontal cortex function theory to cognitive aging. Psychological Bulletin, 120, 272–292). A group of young and a group of older adults took a recognition test in which they classified their responses according to Gardiner, J. M., & Richarson-Klavehn, A. (2000). Remembering and Knowing. In E. Tulving & F. I. M. Craik (Eds.), The Oxford Handbook of Memory. Oxford University Press. remember-know-guess paradigm. Subsequently, participants completed processing speed and executive function tests. The results showed that among the older participants, R responses decreased, but K responses did not. Moreover, a hierarchical regression analysis supported the view that the effect of age in recollection experience is determined by frontal lobe integrity and not by diminution of processing speed.

自Luck等人的研究以来,诸多研究者对客体信息在视觉工作记忆中的表征与存储问题进行了探讨。现有研究主要采用呈现于静态场景的客体作为刺激材料,而不涉及对客体运动特征信息的短时存储。本研究结合多客体追踪范式和视觉工作记忆的变化觉察范式,通过比较检测项全部呈现方式与单检测项呈现方式条件下,客体运动速度的视觉工作记忆绩效,探讨了多个客体的运动速度信息在工作记忆中的存储方式和容量问题。结果表明,在工作记忆中能够存储约3仑独立客体的运动速度信息。     

Experimental control of nodality via equal presentations of conditional discriminations in different equivalence protocols under speed and no-speed conditions

A within-participant comparison of simple-to-complex, complex-to-simple, and simultaneous protocols was conducted establishing different sets of three 7-member equivalence classes for 4 undergraduate students. The protocols were implemented under either accuracy-only or accuracy-plus-speed conditions while keeping number of presentations of training and testing trials equal. The results partially support previous reports of differential effects on acquisition, with participants completing more blocks in training under the simultaneous than the complex-to-simple and the simple-to-complex protocols. Across the protocols, however, the number of trials completed to criterion did not vary systematically. More important, response speed and accuracy did not decrease as a function of nodal number, with or without the speed contingency, or under any protocol. The latter results challenge the generality of previous reports of the nodality effect and the notion of "relatedness" of equivalence-class members, and support a reinforcement-contingency, instead of a structural, perspective on equivalence-class formation.     

The phenotypic and genotypic relation between working memory speed and capacity

This study examined the phenotypic and genotypic relationship between working memory speed (WMS) and working memory capacity (WMC) in 12-year-old twins and their siblings (N = 409). To asses WMS all children performed a reaction time task with three memory loads from which a basic mental speed measure and the derived slope were used. WMC was measured with two subtests of the WISC-R, namely Arithmetic and Digit Span. The phenotypic correlations among the WMS and WMC indices were around − 0.30. Heritabilities for all variables ranged from 43% to 56%. Structural equating modelling revealed that a model with two genetic factors, representing WMS and WMC, which were correlated (− 0.54) fitted the data best, indicating that WMS and WMC are partly mediated by the same set of genes and partly by separate sets of genes. When general IQ was simultaneously analysed with the data the correlation between the genetic factors for WMS and WMC decreased (− 0.25), but was still significant. This means that  50% of the genetic correlation between WMS and WMC is explained by IQ.     

On the glass transition temperature and the elastic properties in Zr-based bulk metallic glasses

The temperature dependence of the elastic moduli was estimated from ultrasound time of flight measurements performed on bulk metallic glasses of composition Zr_{63? x} Cu₂₄Al _x Ni₁₀Co₃. Using the corresponding values at the glass transition temperature, the local atomic strain was determined. The obtained values for the critical atomic strain calculated for 8 at%?<?x?<?15 at% are close to the predicted universal criterion derived from a topological model, but may also reflect the difference in the chemical interaction that are not accounted by a topological approach.
