Emotional irritation before mental stress is associated with enhanced peripheral norepinephrine

Research suggests equivocal findings on associations of catecholamines and mood. Our study investigated the associations of emotional state, blood pressure and catecholamines in 55 healthy males undergoing mental stress. We especially checked the reported link between norepinephrine (NE) and emotional irritation. Blood pressure (SBP, DBP) and heart rate (HR) were continuously monitored. NE and epinephrine (EPI) were measured before, after, and 20 minutes after stress. Participants were divided into irritated versus non-irritated and anxious versus non-anxious subjects by median split on their baseline questionnaires. The task elicited significant cardiovascular, hormonal, and psychological stress responses. NE levels were significantly correlated with irritation before stress. Irritated subjects showed significantly higher DBP and NE than non-irritated subjects. The higher NE and DBP levels in the irritated participants suggest detrimental psycho-physiological interrelations promoting the development of stress-mediated cardiovascular diseases. Heightened emotional irritation before stress may be regarded as a psychological risk factor.     

A study of the perceived recognition affecting the adoption of innovation with respect to the online game in Taiwan.

The potential of online games to become a major global business and the existence of limited related references led to the current study. In this study, Rogers's diffusion of innovation (DOI) theory is applied to investigate the principles for the adoption of online games in Taiwan. The findings suggest that relative advantages and compatibility both have a significant effect on the adoption of online games for purposes of amusement, with the former being more important for early gamers and the latter being regarded as more critical for later gamers. In addition, complexity is found to impede online game diffusion and is regarded as the most important facilitator.     

The self and social cognition: the role of cortical midline structures and mirror neurons

Recent evidence suggests that there are at least two large-scale neural networks that represent the self and others. Whereas frontoparietal mirror-neuron areas provide the basis for bridging the gap between the physical self and others through motor-simulation mechanisms, cortical midline structures engage in processing information about the self and others in more abstract, evaluative terms. This framework provides a basis for reconciling findings from two separate but related lines of research: self-related processing and social cognition. The neural systems of midline structures and mirror neurons show that self and other are two sides of the same coin, whether their physical interactions or their most internal mental processes are examined.     

Balancing Elder Care Responsibilities and Work: The Impact on Emotional Health

The current study investigated the effects of balancing elder care and work on emotional health. Responses from 43 retired caregivers, 211 not retired caregivers, 49 retired non-caregivers, and 224 not retired non-caregivers, who had participated in the national Health and Retirement Study, served as the data base. Results indicate that Caregiver Status (Caregiver vs. Non-caregiver) and Retirement Status (Retired vs. Not Retired) interact, depending on the measure of emotional health. The relationship between the number of depression symptoms reported and Caregiver Status depended on whether the respondent was also retired or employed; a significant interaction was not found when emotional health was measured with one overall item. A significant difference was not found between employed caregivers and employed non-caregivers, in terms of emotional health. Employed caregivers who gave more caregiving hours did report poorer emotional health than employed caregivers who gave fewer hours. Female caregivers reported more depression symptoms than male caregivers. The results suggest that employers may need to develop interventions which may help caregivers who are highly involved with caregiving responsibilities.     

Cultural influences on responses to items on the strong interest inventory

This study examined racial/ethnic group differences on an interest inventory at the item level using differential bundle functioning (DBF) analyses. Specifically, responses of males and females from five different racial/ethnic groups (N=3750) on the General Occupational Themes of the Strong were examined. Items were grouped together based on substantive considerations to determine if they functioned differentially due to racial/ethnic group differences in role modeling, perceptions of opportunities/barriers, familiarity with activities, and cultural expectations, as opposed to true racial/ethnic group differences in interests. Very high levels of DBF were found for most of the item sets considered in this study, implying that diverse cultural groups have a different conditional probability of endorsing some sets of items due to the items measuring a secondary trait in addition to the main trait the scale was designed to measure.     

Aroused at Home: Basic Autonomic Regulation during Orthostatic and Physical Activation is Altered in Children with Social Anxiety Disorder

Previous research has documented altered autonomic nervous system (ANS) reactivity to laboratory-based social stress tasks in children with social anxiety disorder (SAD). It is unclear, however, whether these alterations are caused by the unfamiliar and possibly threatening lab environment or whether they generalize to other, more representative contexts. Sympathetic and parasympathetic autonomic functioning was assessed in the home (minimizing environmental threat) during a supine baseline phase and two physical activation phases (orthostatic stress, stair stepping) in children (9–13 years) with SAD (n?=?27) and healthy control children (n?=?27). Relative to controls, children with SAD showed tonic autonomic hyperarousal as indicated by higher heart rate and electrodermal activity during the supine baseline phase. Further, there was evidence for stronger cardiac and vascular sympathetic reactivity (T-wave amplitude, pulse wave transit time) to moderate physical activation in children with SAD. Higher autonomic arousal during rest was related to measures of trait social anxiety and general psychopathology. Groups did not differ on parasympathetic parameters. Our results extend previous laboratory findings and provide the first evidence for alterations in children with SAD during basal autonomic regulation and in the absence of explicit social evaluative threat. They may further help to clarify conflicting study results from previous laboratory studies. The findings underline the importance of psychophysiological assessment using different environments and tasks to elucidate the physiological bases of SAD.     

Structural and Community Change Outcomes of the Connect‐to‐Protect Coalitions: Trials and Triumphs Securing Adolescent Access to HIV Prevention,Testing, and Medical Care

Connect to Protect (C2P), a 10‐year community mobilization effort, pursued the dual aims of creating communities competent to address youth's HIV‐related risks and removing structural barriers to youth health. We used Community Coalition Action Theory (CCAT) to examine the perceived contributions and accomplishments of 14 C2P coalitions. We interviewed 318 key informants, including youth and community leaders, to identify the features of coalitions’ context and operation that facilitated and undermined their ability to achieve structural change and build communities’ capability to manage their local adolescent HIV epidemic effectively. We coded the interviews using an a priori coding scheme informed by CCAT and scholarship on AIDS‐competent communities. We found community mobilization efforts like C2P can contribute to addressing the structural factors that promote HIV‐risk among youth and to community development. We describe how coalition leadership, collaborative synergy, capacity building, and local community context influence coalitions’ ability to successfully implement HIV‐related structural change, demonstrating empirical support for many of CCAT's propositions. We discuss implications for how community mobilization efforts might succeed in laying the foundation for an AIDS‐competent community.     

Disaggregated pluralistic theories of global distributive justice – a critique

Pluralistic theories of global distributive justice aim at justifying a plurality of principles for various subglobal contexts of distributive justice. Helena de Bres has recently proposed the class of disaggregated pluralistic theories, according to which we should refrain from defending principles that apply to the shared background conditions of such subglobal contexts. This article argues that if one does not justify how these background conditions should be regulated by principles of a just global basic structure, then the (apparent) realization of the principles that are justified for the subglobal contexts of distributive justice can erode and undermine justice over time. For example, the realization of justice in international trade might undermine climate justice, at least if climate justice requires increasing tariffs (in order to mitigate greenhouse gas emissions) but justice in international trade calls for reducing tariffs (in order to create a level playing field). Principles of a just global basic structure would have to ensure that such justice-eroding spillover effects from one to another context of justice do not occur. Finally, the article responds critically to de Bres’ objections that an account of a just global basic structure is too idealistic, not action guiding, and superfluous.
