Adherence to Mediterranean diet and risk of prostate cancer

In Europe, countries following the traditional Mediterranean Diet (MeDi), particularly Southern European countries, have lower prostate cancer (PCa) incidence and mortality compared to other European regions. In the present study, we investigated the association between the MeDi and the relative risk of PCa and tumor aggressiveness in a Spanish population. Among individual score components, it has been found that subjects with PCa were less likely to consume olive oil as the main culinary fat, vegetables, fruits and fish than those without. However, these differences were not statistically significative. A high intake of fruit, vegetables and cooked tomato sauce Mediterranean style (sofrito) was related to less PCa aggressiveness. Results showed that there are no differences in the score of adherence to the Mediterranean dietary patterns between cases and controls, with mean values of 8.37?±?1.80 and 8.25?±?2.48, respectively. However, MeDi was associated with lower PCa agressiveness according to Gleason score. Hence, relations between Mediterranean dietary patterns and PCa are still inconclusive and merit further investigations. Further large-scale studies are required to clarify the effect of MeDi on prostate health, in order to establish the role of this diet in the prevention of PCa.     

Strategic Network Orchestration in Emerging Markets: China's Catch‐up in the High‐Speed Train Industry

Transitioning from catch‐up in production to catch‐up in innovation capabilities is essential to emerging market firms (EMFs) achieving internationalization and a competitive advantage. While some EMFs are now positioned among the world's most advanced firms, many struggle to become independent innovators. Thus, understanding how EMFs can develop internal absorptive capacity and progress towards catching up in innovation capabilities remains important. Our study seizes this research opportunity and develops a network‐based explanation of catch‐up, which complements existing technological and organizational explanations. Specifically, we address the question of ‘How does the orchestration of collaborative networks enable EMFs to catch up in production and innovation capabilities?’ by describing an important yet under‐researched process of strategic network orchestration and showcasing the dynamic interdependencies between network orchestration and organizational learning. Our study provides a detailed account of Chinese high‐speed train (HST) development from 1990 to 2020 and opens the possibility for future research on network orchestration in emerging market contexts. This provides EMF managers with a set of actionable network orchestration mechanisms that can be used when designing and purposefully managing their strategic nets of domestic and foreign partners.     

‘It's not acceptable for the husband to stay at home': Taking a discourse analytical approach to capture the gendering of work

This article illustrates some of the ways in which the notion of (paid) work is actively being gendered, and how these gendering processes take place not only through organizational practices but also in discourses that circulate outside an organization in the private domain. Drawing on 15 in‐depth interviews with women who opted out of their own professional career in order to accompany their husbands on their overseas work assignment to Hong Kong, we demonstrate some of the benefits of using a discourse analytical approach to capturing and identifying the processes through which these women actively (although not necessarily consciously) gender the notion of work, thereby reinforcing the gender order and its male bias. We argue that identifying and making visible these gendered and gendering practices is an important component of, and a potential trigger for, change both in organizations as well as private contexts.     

House Damage Revisited: How Type of Damage and Perpetrating Actor Affect Intentions and Actions of IDPs in Iraq

House damage has been a widespread consequence of the Islamic State (IS) crisis in Iraq. However, house and property damage per se is not a factor limiting return. The type and timing in which property destruction occurs – during direct military confrontation or before/after it – and the alleged perpetrator constitute better indicators of inhibited returns as type of damage and inflicting actor appear to have a significant effect on fears, perceptions and intentions of IDPs and returnees.     

Adolescent Online Gambling in Cyprus: Associated School Performance and Psychopathology

This paper presents results from the study of gambling behaviors in a representative sample of Cypriot high-school students. The aim of the study was to ascertain epidemiology of adolescent online gambling in Cyprus and possible correlates. The sample consisted of 2,684 students (48.5 % boys, 51.5 % girls) from the first grades of junior (Gymnasium) and senior (Lyceum) high school. Our results indicate that gamblers presented with lower school achievement and related expectations while scoring consistently higher on measures of Internet addiction, parental bonding and psychopathology. Discriminant analysis revealed two profiles which explained the most variance in gambling behavior; the first profile that corresponded to more explained variance was the student with higher psychopathology, less prosocial behavior, higher Internet addiction score with higher frequencies of online activities and moderate levels of truancy and lower expectation of school achievement. The second profile was that of a student who reported less psychopathology, more prosocial behavior, less involvement with the Internet in general but skipped classes more and his prospects on finishing high school were even slimmer. These results will be utilized in the design of a comprehensive prevention program in an effort to combat online addictive behaviors.     

Open spaces for dialogue promoting mental health as a social work education methodology

ABSTRACT

The authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience.     

Complementary person-supervisor fit: An investigation of supplies-values (S-V) fit,leader-member exchange (LMX) and work outcomes

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee's work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of matched leader-employee dyads (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated.     

Uniform Convergence of Compactly Supported Wavelet Expansions of Gaussian Random Processes

New results on uniform convergence in probability for expansions of Gaussian random processes using compactly supported wavelets are given. The main result is valid for general classes of non stationary processes. An application of the obtained results to stationary processes is also presented. It is shown that the convergence rate of the expansions is exponential.
