Convergence towards a European strategic culture? A constructivist framework for explaining changing norms.

The article contributes to the debate about the emergence of a European strategic culture to underpin a European Security and Defence Policy. Noting both conceptual and empirical weaknesses in the literature, the article disaggregates the concept of strategic culture and focuses on four types of norms concerning the means and ends for the use of force. The study argues that national strategic cultures are less resistant to change than commonly thought and that they have been subject to three types of learning pressures since 1989: changing threat perceptions, institutional socialization, and mediatized crisis learning. The combined effect of these mechanisms would be a process of convergence with regard to strategic norms prevalent in current EU countries. If the outlined hypotheses can be substantiated by further research the implications for ESDP are positive, especially if the EU acts cautiously in those cases which involve norms that are not yet sufficiently shared across countries

Who's Cueing Whom? Mass-elite linkages and the future of European integration

The 2005 French and Dutch referendum campaigns were characterized by an alleged disconnect between pro-European political elites and Eurosceptic masses. Past evidence regarding elite-mass linkages in the context of European integration has been conflicting. Whereas some scholars argue that political elites respond to the changing preferences of their electorates, others suggest that party elites cue the mass public through a process of information and persuasion. We contend that these conflicting results stem from the reciprocal nature of elite-mass linkages and estimate a series of dynamic simultaneous equations models to account for this reverse causation. Using Euro-barometer and expert survey data from 1984-2002, we find evidence of a dual-process model, whereby party elites both respond to and shape the views of their supporters. We also find that the strength of these results is contingent on several factors, including the type of electoral system, intra-party dissent and voter characteristics.

Feasibility and outcome of an online streamed yoga intervention on stress and wellbeing of people working from home during COVID-19

BACKGROUND: The outbreak of COVID-19 and its associated measures has resulted in a sizeable working population transitioning to working from home (WFH), bringing additional challenges, and increasing work-related stress. Research has indicated that yoga has promising potential in reducing stress in the workplace. However, there are very few studies exploring the impact of online streamed yoga on stress management for people-WFH. OBJECTIVE: To investigate the feasibility and outcome of an online streamed yoga intervention on stress and wellbeing of people-WFH during COVID-19. METHODS: A six-week pilot randomized controlled trial (RCT) yoga intervention was designed with yoga (n = 26) and a wait-list control group (n = 26). A mixed two-way ANOVA was used to assess changes in standardised outcome measures at baseline and post-intervention. Likert and open-ended questions assessed enjoyment, acceptability and perceived benefits of the program, which were analysed thematically. RESULTS: Compared with the control, the yoga group reported significant improvements in perceived stress, mental wellbeing, depression and coping self-efficacy, but not stress and anxiety. Participants experienced physical and mental health benefits and reported high acceptability and enjoyment of the intervention. CONCLUSIONS: An online yoga intervention can help people WFH manage stress and enhance wellbeing and coping abilities

Inclusion Body Myositis: Laser Microdissection Reveals Differential Up-Regulation of IFN-γ Signaling Cascade in Attacked versus Nonattacked Myofibers

Sporadic inclusion body myositis (IBM) is a muscle disease with two separate pathogenic components, degeneration and inflammation. Typically, nonnecrotic myofibers are focally surrounded and invaded by CD8+ T cells and macrophages. Both attacked and nonattacked myofibers express high levels of human leukocyte antigen class I (HLA-I) molecules, a prerequisite for antigen presentation to CD8+ T cells. However, only a subgroup of HLA-I+ myofibers is attacked by immune cells. By using IHC, we classified myofibers from five patients with sporadic IBM as attacked (AIBM) or nonattacked (NIBM) and isolated the intracellular contents of myofibers separately by laser microdissection. For comparison, we isolated myofibers from control persons (HCTRL). The samples were analyzed by microarray hybridization and quantitative PCR. HLA-I up-regulation was observed in AIBM and NIBM, whereas HCTRL were negative for HLA-I. In contrast, the inducible chain of the interferon (IFN) γ receptor (IFNGR2) and several IFN-γ–induced genes were up-regulated in AIBM compared with NIBM and HCTRL fibers. Confocal microscopy confirmed segmental IFNGR2 up-regulation on the membranes of AIBM, which positively correlated with the number of adjacent CD8+ T cells. Thus, the differential up-regulation of the IFN-γ signaling cascade observed in the attacked fibers is related to local inflammation, whereas the ubiquitous HLA-I expression on IBM muscle fibers does not require IFNGR expression

Policy implications of achievement testing using multilevel models: the case of Brazilian elementary schools

Large-scale educational assessment has been established as source of descriptive, evaluative and interpretative information that influence educational policies worldwide throughout the last third of the twentieth century. In the 1990s the Brazilian Ministry of Education developed the National Basic Education Assessment System (SAEB) that regularly measures management, resource and contextual school features and academic achievement in public and private institutions. In 2005, after significant piloting and review of the SAEB, a new sampling strategy was taken and Prova Brasil became the new instrument used by the Ministry to assess skills in Portuguese (reading comprehension) and Mathematics (problem solving), as well as collecting contextual information concerning the school, principal, teacher, and the students. This study aims to identify which variables are predictors of academic achievement of fifth grade students on Prova Brasil. Across a large sample of students, multilevel models tested a large number of variables relevant to student achievement. This approach uncovered critical variables not commonly seen as significant in light of other achievement determinants, including student habits, teacher ethnicity, and school technological resources. As such, this approach demonstrates the value of MLM to appropriately nuanced educational policies that reflect critical influences on student achievement. Its implications for wider application for psychology studies that may have relevant impacts for policy are also discussed

Suicidal Behavior and Alcohol Abuse

Suicide is an escalating public health problem, and alcohol use has consistently been implicated in the precipitation of suicidal behavior. Alcohol abuse may lead to suicidality through disinhibition, impulsiveness and impaired judgment, but it may also be used as a means to ease the distress associated with committing an act of suicide. We reviewed evidence of the relationship between alcohol use and suicide through a search of MedLine and PsychInfo electronic databases. Multiple genetically-related intermediate phenotypes might influence the relationship between alcohol and suicide. Psychiatric disorders, including psychosis, mood disorders and anxiety disorders, as well as susceptibility to stress, might increase the risk of suicidal behavior, but may also have reciprocal influences with alcohol drinking patterns. Increased suicide risk may be heralded by social withdrawal, breakdown of social bonds, and social marginalization, which are common outcomes of untreated alcohol abuse and dependence. People with alcohol dependence or depression should be screened for other psychiatric symptoms and for suicidality. Programs for suicide prevention must take into account drinking habits and should reinforce healthy behavioral patterns

Ventromedial prefrontal cortex stimulation enhances memory and hippocampal neurogenesis in the middle-aged rats

© 2015, eLife Sciences Publications Ltd. All Rights Reserved. Memory dysfunction is a key symptom of age-related dementia. Although recent studies have suggested positive effects of electrical stimulation for memory enhancement, its potential targets remain largely unknown. In this study, we hypothesized that spatially targeted deep brain stimulation of ventromedial prefrontal cortex enhanced memory functions in a middle-aged rat model. Our results show that acute stimulation enhanced the short-, but not the long-term memory in the novel-object recognition task. Interestingly, after chronic high-frequency stimulation, both the short- and long-term memories were robustly improved in the novel-object recognition test and Morris water-maze spatial task compared to sham. Our results also demonstrated that chronic ventromedial prefrontal cortex high-frequency stimulation upregulated neurogenesis-associated genes along with enhanced hippocampal cell proliferation. Importantly, these memory behaviors were strongly correlated with the hippocampal neurogenesis. Overall, these findings suggest that chronic ventromedial prefrontal cortex high-frequency stimulation may serve as a novel effective therapeutic target for dementia-related disorders.published_or_final_versio

Postoperative outcomes in oesophagectomy with trainee involvement

BACKGROUND: The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS: Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS: Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION: Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery
