BACKGROUND The debate regarding diagnostic classification systems in psychiatry(categorial vs dimensional systems)has essential implications for the diagnosis,prevention and treatment of stress *** previously found a unique pattern of stress reaction in a study executed during the coronavirus disease 2019 pandemic using large representative samples in two countries,and termed it the Complex Stress Reaction Syndrome(CSRS).AIm To investigate CSRS,Type A(psychiatric symptoms,spanning anxiety,depression,stress symptoms,and posttraumatic stress disorder(PTSD)),with or without long-coronavirus disease(COVID)residuals(CSRS,Type B,neuropsychiatric symptoms spanning cognitive deficits and fatigue,excluding systemic symptoms).Our two-tailed hypothesis was that CSRS is a condition related to an unrecognized type of stress reaction in daily life in the general population(Type A)or that it is related to the severe acute respiratory syndrome coronavirus 2 infection and its long-COVID residuals(Type B).mETHODS 977 individuals in four continents(North America,Europe,Australia and the middle East)completed the online study questionnaire in six languages using the Qualtrics *** study was managed by six teams in six countries that promoted the study on social *** questionnaire assessed anxiety,depression,stress symptoms and PTSD(CSRS,Type A),cognitive deficits and fatigue(CSRS,Type B).The data were analyzed using Proportion Analyses,multivariate Analysis of Co-Variance(mANCOVA),linear regression analyses and validated clinical cutoff *** The results of the Proportion Analyses showed that the prevalence of 4 symptoms spanning anxiety,depression,stress symptoms,and PTSD was significantly higher than the most prevalent combinations of fewer symptoms across 4 continents,age groups,and *** supports the transdiagnostic argument embedded in the CSRS(Type A).The same pattern of results was found in infected/recovered *** prevalence of the

压敏胶粘剂工业一向依赖于溶剂基体系,它们当中的许多聚合物和用于改性的树脂都溶于溶剂中。然而,压敏胶工业面临着经济、环境和政治原因造成的种种问题。这些问题包括溶剂供应的减少和成本的增加,能源成本的上升,以及溶剂蒸气的散发受到限制。溶剂的供应和价格一向取决于对溶剂的需求量,有时还受不可预见的政治因素的影响,溶剂的供应和价格情况可能会不断循环。支配溶剂的供应和价格的因素也同时左右能源供应和价格。很自然,能源也面临相似的问题。现行有关挥发溶剂散发的法规,目前所考虑到的将来的法规,以及使用有机

本文研究了未掺杂和掺磷SiO2玻璃膜的台阶覆盖。简要地讨论了在决定台阶覆盖质量中起作用的各种参数。评价了各种淀积工艺的台阶覆盖能力。被比较的工艺有常压CVD,低温、低压CVD（Silox）,中温、低压CVD（TEOS）和等离子增强CVD。报导了采用中温低压技术淀积未掺杂玻璃时得到的台阶覆盖与参数的关系。证明台阶覆盖的质量强烈地依赖于淀积条件。也证明台阶覆盖质量随着TEOS流率和反应器中分子滞留时间的增加而改善。氮、氧、或磷烷/氮混合物加到TEOS中会使淀积工艺的台阶覆盖能力变差。这种中温、低压CVD工艺的台阶覆盖在650-780℃的范围内与淀积温度无关。

建立混合网络把专业人员与组织联结起来,是为患者提供整合性护理的一种常用方法。最新研究文献认为,这些网络的成功实施需要以一种社会认知视角对利益相关者的心理模式与思维过程进行优选区分、调查研究和比较。本文的目的是研究加拿大安大略省名为"保健链"的整合性护理网络在实施过程中临床方面和管理方面的利益相关者的思想分歧,并描述促进利益相关者共同学习和培养更具一致性的观点的策略。根据共同心理模式理论和基于实践的学习理论,我们对"保健链"实施中涉及的55位医疗保健专业人员和管理者的访谈数据进行了二级分析。利益相关者在看待"保健链"的设计与方法("策略认知的心理模式")方面、在了解对方以及如何与对方合作("关系认知的心理模式")方面都存在分歧,我们对这些分歧案例进行了识别。我们还界定了促进学习与尽可能使心理模式统一的四种策略。该研究的结果会有助于指导利益相关者为提供整合性护理而就共同学习与协调行动展开对话。
