Crystal growth velocity in deeply undercooled Ni–Si alloys

The crystal growth velocity of Ni₉₅Si₅ and Ni₉₀Si₁₀ alloys as a function of undercooling is investigated using molecular dynamics simulations. The modified imbedded atom method potential yields the equilibrium liquidus temperatures T _L?≈?1505 and 1387?K for Ni₉₅Si₅ and Ni₉₀Si₁₀ alloys, respectively. From the liquidus temperatures down to the deeply undercooled region, the crystal growth velocities of both the alloys rise to the maximum with increasing undercooling and then drop slowly, whereas the athermal growth process presented in elemental Ni is not observed in Ni–Si alloys. Instead, the undercooling dependence of the growth velocity can be well-described by the diffusion-limited model, furthermore, the activation energy associated with the diffusion from melt to interface increases as the concentration increases from 5 to 10?at.% Si, resulting in the remarkable decrease of growth velocity.     

Does longer job tenure help or hinder job performance?

There are two competing theoretical perspectives on how job tenure might affect job performance. Human capital theory suggests that as knowledge and skill increase with greater tenure, job performance will improve as well. In contrast, the literature on job design suggests that as job tenure increases, employees are likely to become more bored and less motivated at work. Consequently, the gains from human capital acquisition might be offset by losses of motivation. To examine these competing perspectives, we conducted meta-analyses on the relationships of job tenure with four types of job performance: core task performance, citizenship behavior, creativity and innovative behavior, and counterproductive work behavior. The results support the second perspective, as both the linear and curvilinear relationships of job tenure with the four types of job performance are weak. Further, the results do not change in strength across type of research design, job industry, age, or gender.     

Anxiety reactivity and anxiety perseveration represent dissociable dimensions of anxiety vulnerability: A replication and extension

Trait anxiety is a unitary construct reflecting individual differences in the tendency to experience anxious symptomatology, typically measured with questionnaires such as the Spielberger Trait Anxiety Inventory (STAI‐T). Recent research by Rudaizky, Page, and MacLeod has found evidence that two different dimensions of trait anxiety account for independent variance in trait anxiety scores. These dimensions are anxiety reactivity (AR), reflecting the probability of experiencing an anxious reaction, and anxiety perseveration (AP), reflecting the persistence of anxious symptoms once elicited. There are two key issues addressed in this study: first, the replicability of Rudaizky et al.'s findings and second, the ability of the measures of AR and AP developed by Rudaizky et al. to predict independent variance in STAI‐T scores after statistically controlling for variance shared with a measure of depression. Regression analysis determined that AR and AP do account for independent variance in STAI‐T trait anxiety scores even after statistically controlling for depression. The implications of these findings for the understanding of anxiety vulnerability are discussed.     

Validating Measures of Psychological Well-being by Contrasting Samples Employed in Hazardous and Less Hazardous Work

The study investigated whether differences between contrasting groups reflect significant differences in psychological well-being scores. Membership of hazardous vs. less hazardous occupations in the same profession served as proxy measures of well-being. Antonovsky's Sense of Coherence (SOC), Block & Kremen's Ego-resiliency, and Goldberg's Emotional Stability scales were validated. Study 1 compared mine rescue team members and ordinary miners (n = 34, 41) and Study 2 police special task force members and regular officers (n = 43, 41). In Study 1, SOC and job satisfaction predicted group membership. In Study 2, satisfaction with life and extraversion scales predicted group membership, as did SOC in a secondary analysis. The SOC scale could predict psychological well-being in hazardous work settings.     

So viel? So oft?

Psychoanalysis is usually only considered as a treatment option when other therapeutic procedures have not resulted in any lasting improvement or in particularly burdensome situations. In psychoanalysis, it is assumed that the unconscious is reflected in a structural pathology of the personality and, based on repetition compulsion, presents itself again and again in the person’s life and relationships with varying psychiatric symptoms. Within the framework of more frequent psychoanalytic treatment in an outpatient clinic, these established structures can be identified and altered as transference and countertransference in the therapeutic relationship. This requires elaborate and systematic reflection on the basis of modern theoretical and clinical developments.     

PROMOTING THE PSYCHO-SOCIAL WELL-BEING OF INTERNATIONAL STUDENTS THROUGH MINDFULNESS: A FOCUS ON REGULATING DIFFICULT EMOTIONS

ABSTRACT

This qualitative study explores the potential of a mindfulness programme for providing psycho-social support to international students in higher education. The article focuses on analysing the nature of emotional distress among students, how they regulate difficult emotions, and the effects of the mindfulness programme on emotion regulation. For this purpose, in-depth interviews were conducted with students before and after the mindfulness programme, and the weekly mindfulness sessions were observed. The study identified that stress, anxiety, anger, sadness, loneliness and insecurity were among the most difficult emotions experienced by international students. Through mindfulness, students improved in awareness of their emotions, learnt to relate to difficult emotions more constructively, and regulated negative emotions more effectively. Nevertheless, many suggested that they would have welcomed more attention to emotion regulation, as it was identified as a key challenge in their lives. These findings have important implications for the psycho-social well-being and academic achievement of international students.     

KUZGUNCUK AS A VILLAGE OF MUTUAL RESPECT AND HARMONY: MYTH OR REALITY?

My research concentrates on the Jews of Istanbul and especially on the Kuzguncuk neighbourhood. My aim is to understand the changes within the social structure of the Jewish community of Turkey and its relationship with the dominant Muslim society. Different from other important Jewish neighbourhoods of Istanbul such as quarters in Balat, Haskoy and Galata-Pera district, Kuzguncuk is known as the “village of harmony” and a “place in which all religious and ethnic groups live in peace, harmony and mutual respect”. In this article, I try to answer the question of whether this is a myth or the real experience of Kuzguncuk. Whether a myth or a real experience, can it be a model for people “living together in peace and harmony”? I will also explore the situation of Jews after the foundation of the Turkish republic. In order to understand the changing structure of Jews of Kuzguncuk, I conducted interviews with seven actual and former residents of Kuzguncuk, who now live in Israel, Kuzguncuk and other districts of Istanbul.     

Sport and Thought. Football as therapy: A year in the life of an inner city project

‘Sport and Thought. Football as therapy, A year in the life of an inner city project’ is a paper based on a way of working that fuses football and psychodynamic thinking. The project was set up at inner city all-boys secondary school in London and was created in response to the growing need for a therapeutic intervention which was accessible to adolescent boys who would not engage via more traditional therapeutic routes. The project works with adolescents experiencing behavioural and emotional difficulties. Sport and Thought is a way of working with adolescents that fuses the sport of football, psychodynamic thinking and theory to create a space to encourage thought and act as a catalyst to promote emotional and behavioural change. Sport and Thought believes an individual’s reactions within a sporting context are no different to a societal one, and thus the sport of football can be used to enable participants to consider their own emotional and behavioural traits, and the underlying reasoning behind them.     

Russification as a factor in religious conversion. Making Lenin roll over in his grave

The Soviet project was as thoroughly atheist as any geopolitical system seen on the world stage. Yet in a way that V.I. Lenin could have never imagined, one of the main objectives of Soviet authorities has now become a significant factor in Central Asian Muslims converting to Christianity. Russification is the term normally used to describe the social process, whereby non-Russian peoples of the Soviet Union became acculturated into Russian patterns of life, thought and worldview during the Soviet era. The result was that many Muslims inhabited both Soviet/Russian and Muslim cultural space, thus creating a new cultural identity that facilitated religious conversion away from Islam. This field research report uses the lens of personal conversion stories to examine some aspects of this phenomenon. Also, the range of personal experiences points towards the need to understand Russification as a spectrum of acculturation.     

Two-Year-Olds' Object Retrieval Based on Television: Testing a Perceptual Account

Two-year-olds frequently fail to use information provided by video to find objects hidden in an adjacent room. Schmitt and Anderson (2002) hypothesized that they fail to map the 2-dimensional (2D) video image onto the 3D layout of the search space. Two experiments tested whether 2-year-olds can successfully use information from video when the search space is 2D or when the information is provided verbally (by telling the child where the toy is hidden). In both experiments, children performed poorly in the video conditions but performed well in direct live experience comparison conditions, contradicting Schmitt and Anderson's hypothesis. Performance was above chance on the first trial in the video conditions, suggesting that 2-year-olds do have a memory of the hiding location, albeit one that is easily disrupted by perseverative errors on subsequent trials. Overall, the results are most consistent with the hypothesis that very young children give priority to direct experience over mediated information.
