Emoticons in computer-mediated communication: social motives and social context.

This study investigated the role of emoticons in computer-mediated communication (CMC). The study consisted of an online questionnaire about the social motives for emoticon use and an experimental part in which participants (N = 1,251) had to respond to short Internet chats. In these chats, the interaction partner (friend vs. stranger) and the valence of the context (positive vs. negative) were manipulated. Results showed that emoticons are mostly used to express emotion, to strengthen a message, and to express humor. Furthermore, more emoticons were used in communication with friends than in communication with strangers, and more emoticons were used in a positive context than in a negative context. Participants seem to use emoticons in a way similar to facial behavior in face-to-face communication with respect to social context and interaction partner.     

When Leaders Are Seen as Transformational: The Effects of Organizational Justice1

In 2 studies, we attempted to make a first step toward integrating the literature on transformational leadership and organizational justice. We examined the extent to which justice affects perceptions of transformational leadership. We predicted that especially interactional justice should have strong effects. Study 1 was a vignette study (N = 100) in which distributive, procedural, and interactional justice were manipulated orthogonally. As expected, only interactional justice affected transformational leadership perceptions. Study 2 replicated these results in an organizational field study (N = 257). Distributive and procedural justice affected perceptions of transformational leadership, but when interactional justice was entered in the regression equation, their effects disappeared. Implications for integrating the literature on transformational leadership and organizational justice are discussed.     

The criterion‐related validity of a short commensurate measure of personality‐based person‐organization fit

Our goal was to develop a commensurate measure of personality‐based person‐organization fit and examine its criterion‐related validity for two retention‐related attitudes: job satisfaction and intention to stay. At T0, 637 employees completed our questionnaire. Two years later, at T1, 171 of the original respondents completed our questionnaire again. Results showed that the organizational personality perceptions are relatively stable. Polynomial regression analyses and surface plots revealed that job satisfaction and intention to stay are higher when there is perfect fit between the person and the organization compared to when the person and the organization differ in traits. However, in most cases, we found the work attitudes to be maximized when both the person and the organization score high on the personality traits.     

Phosphodiesterase type 5 (PDE5) inhibition improves object recognition memory: indications for central and peripheral mechanisms

A promising target for memory improvement is phosphodiesterase type 5 (PDE5), which selectively hydrolyzes cyclic guanosine monophosphate (cGMP). In rodents, PDE5 inhibitors (PDE5-Is) have been shown to improve memory performance in many behavioral paradigms. However, it is questioned whether the positive effects in animal studies result from PDE5 inhibition in the central nervous system or the periphery. Therefore, we studied the effects of PDE5 inhibition on memory and determined whether compound penetration of the blood-brain barrier (BBB) is required for this activity. Two selective PDE5-Is, vardenafil and UK-343,664, were tested in the object recognition task (ORT) in both a MK-801- and scopolamine-induced memory deficit model, and a time-delay model without pharmacological intervention. Compounds were dosed 30 min before the learning trial of the task. To determine if the PDE5-Is crossed the BBB, their concentrations were determined in plasma and brain tissue collected 30 min after oral administration. Vardenafil improved object recognition memory in all three variants of the ORT. UK-343,664 was ineffective at either preventing MK-801-induced memory disruption or time-dependent memory decay. However, UK-343,664 attenuated the memory impairment of scopolamine. Vardenafil crossed the BBB whereas UK-343,664 did not. Further, co-administration of UK-343,664 and scopolamine did not alter the brain partitioning of either molecule. This suggests that the positive effect of UK-343,664 on scopolamine-induced memory decay might arise from peripheral PDE5 inhibition. The results herein suggest that there may be multiple mechanisms that mediate the efficacy of PDE5 inhibition to improve memory performance in tasks such as the ORT and that these involve PDE5 located both within and outside of the brain. To further elucidate the underlying mechanisms, the cellular and subcellular localization of PDE5 needs to be determined.     

Recognition of psychopathology with religious content by clergy members: a case vignette study

Clergy members (CMs) frequently offer support and counselling for people with mental health problems. The current study aims to obtain insight into the ability among CMs to recognise psychopathology and need for psychiatric treatment. A random sample of CMs (N?=?143) and a control sample of mental health professionals (MHPs, N?=?73), were compared as to their evaluations of four vignettes. CMs considered the psychiatric states to be related to religious or spiritual problems to a similar degree as they did for the non-psychiatric states. Sensitivity of CMs with regard to the need of psychiatric care for the psychiatric states was modest (66%) and differed significantly from MHPs (96%). Specificity of the CMs was 89%, which was significantly lower than the MHPs (97%). The CMs did recognise psychopathology with religious content but clearly to a lower extent than MHPs. Requests by CMs for education about recognising psychopathology may be considered as justified.     

Intergroup structure and identity management among ethnic minority and majority groups: the interactive effects of perceived stability,legitimacy, and permeability

This paper is an examination, in a natural setting, of the interactive effects of perceived stability, legitimacy, and group permeability on group identification, stereotypes, and group feelings among Turkish‐Dutch and ethnically Dutch participants. The findings strongly support predictions derived from the social identity perspective. For the Turkish‐Dutch, a legitimate interethnic structure meant rather unstable relations and permeable group boundaries. For the Dutch, the same structure implied stability and impermeability. For the Turkish‐Dutch, a response pattern of individual mobility was found: if they viewed ethnic intergroup relations as legitimate and stable, permeability was negatively related to Turkish identification as well as to less stereotyping on the dimension defining Turkish identity. It was also related positively to Dutch identification and in‐group bias in relation to other ethnic minority groups. For the Dutch participants, higher perceived legitimacy was associated with stronger in‐group identification and more positive in‐group evaluation. Additionally, in a legitimate context, stability was, for them, related to a lower stereotyping of the Turkish out‐group on status‐relevant dimensions and more negative feelings towards ethnic out‐groups in general.

Sweet Delight and Endless Night: A Qualitative Exploration of Ordinary and Extraordinary Religious and Spiritual Experiences in Bipolar Disorder

The authenticity of religious and spiritual experiences during mania is an important subject for bipolar patients. The exploration of such experience in bipolar disorder is the central point of this qualitative study. A psychiatrist and a hospital chaplain conducted 35 semi-structured interviews with recovered participants, recruited from mental health care institutions in the Netherlands, the patients’ association and via the internet, about their religious and spiritual experiences during illness episodes and in stable times. A variety in types (such as divine presence, unity, mission, meaningful synchronicity) during mania was reported, which were on a sliding scale with experiences/views in stable times in more than half of the interviews. During depression, absence of religious or spiritual experience was predominant. The reported experiences were viewed by most participants as both authentically religious or spiritual but also related to the disorder, requiring therefore language that transcended medical terminology. Also indicated is the relevance of the results for fundamental discussions about the nature or religious experience.     

Sugar daddies and blessers: A contextual study of transactional sexual interactions among young girls and older men

This mixed method study aimed to gather a contextual understanding of the perspectives of young girls in South Africa with regard to transactional sexual interactions between older men and young girls. Two major narratives of the “sugar daddy” phenomenon have dominated the public discourse on the topic. One emphasises the girls' vulnerability and experience of victimisation, whereas the other highlights their role as social agents with control in such interactions. In this study, the participants acknowledged the heterogeneity among partners in such interactions, which suggests that the phenomenon of “sugar daddies” cannot be explained by a simple narrative. The girls' experiences form a continuum based on the degree of their individual control and the extent of their vulnerability in such an interaction. Contextual factors and social norms influence decisions and experiences in these interactions. The study concludes that these relationships form part of the girls' daily experiences of structural violence as well as gender inequality and can be regarded as a symptom of broader societal structures and norms. Quantitative data investigate the mental health status of the participants, whereas an essentialist/realist thematic analysis of qualitative data explores experiences and perceptions of the girls.     

Stigma by Association Among Family Members of People with a Mental Illness: A Qualitative Analysis

People with mental illness are not the sole recipients of stigmatisation; their immediate family members may be subjected to stigma by association. Through semi‐structured interviews, we investigated experiences of stigma by association among 23 immediate family members of people with mental illness. Participants reported experiencing stigma by association from community members, mental health professionals, and civil servants. Familial relationship, co‐residence, and the gender of participants appeared to play a role in their stigma experiences; parents and spouses reported different manifestations of stigma by association than siblings and children, participants who lived together with their family member with mental illness reported increased experiences of stigma by association, and in contrast to male participants, female participants reported others thinking they are overprotective and as such perpetuated, maintained, or sustained their family members' mental illness. The relevance of these factors points to the need for tailored education and emotional support provision to family members of people with mental illness. Moreover, in‐service training for mental health professionals should include the development of relevant social skills that enable the recognition of familial relationships and roles, and family members' fears, concerns, and problems.

Stress related changes in immunological and psychological variables induced by the preparation and defense of a PhD-thesis

Abstract

Results are reported from a field study on 47 healthy subjects preparing and defending a PhD-thesis in the Netherlands. Measurements before, about and after thesis defense are used to quantify the temporal effects of this perceived stressor on immunological and psychological variables. Moreover, multivariate analysis of variance for repeated measurements was used to explore a potential causal relationship between changes in immune variables and changes in psychological variables. Significant temporal effects were observed for the immunological variables, percentage CD4 cells (p = 0.037), the proliferative response to pokeweed mitogen (p = 0.040), concanavalin A 10 μg/ml (p = 0.010) and concanavalin A 40 μg/ml (p = 0.005) and the psychological variables, average subjective distress (p = 0.002), highest subjective distress (p = 0.000) and the coping strategy depressive reaction pattern (p= 0.02). No evidence was obtained for a causal relation between the immunological and psychological variables.
