我国出口信用保险与出口贸易动态关系研究--来自沿海经济圈省际面板数据的经验证据

利用沿海经济圈省际面板数据作为样本,使用面板向量自回归模型研究了出口信用保险与出口贸易的动态关系。研究发现：出口信用保险在短期内能促进出口贸易,长期内不具有持续效应;出口贸易提高出口信用保险需求水平的能力有限。两者呈现出非对等关系,出现这一现象的主要原因是保险费率垄断。     

不抛弃，不放弃——用读者反应理论看瓦尔特·莫瑞尔和印家厚的不同人生

读者反应理论强调以读者为中心,认为读者是文本意义的生产者,这样对文本的解读就会因人而异。利用读者反应理论的观点探讨小说《儿子与情人》和《烦恼人生》中两位男主人公——瓦尔特·莫瑞尔和印家厚所经历的人生的酸甜苦辣、喜怒哀乐,试图说明相似时代背景下演绎出的不同人生：放弃与坚持。     

符号学视角下欠额翻译与超额翻译的规避问题

本文依据社会符号学的基本理论及其代表人物尤金.奈达寻求“动态对等”,讲求社会效应的翻译标准,提出了界定欠额翻译与超额翻译的标准——译语读者的反应,并进而从准确理解源语和运用规避策略两大方面探讨如何在翻译实践中尽量减少欠额翻译与超额翻译的发生。     

恭维语回应中的语用迁移研究

从中西方礼貌原则入手，研究中国英语学习者在恭维语回应中言语行为的使用，分析这一言语行为的语用迁移类型，并分析导致语用迁移的因素，从而在英语教学过程中有意识地学习和掌握语言知识与语用知识。     

建立高校网络舆情快速响应机制的探究

高校网络舆情内容的多元性与分散性、突发性、创造和参与主体的特殊性、感性化和易控制等特点与目前迟缓的落后的响应机制的突出矛盾,给高校思想政治教育带来了挑战,不利于大学生正确世界观、人生观和价值观的形成。在坚持正确导向,用先进思想与文化占领高校网络的指导思想下,运用创新手段,统一协调校内各种资源,提出了层级监控报送体系、快速应急联动机制和线下沟通疏导教育的三位一体的网络舆情快速响应机制的实施方案。这对加强网络队伍建设,巩固校内多部门联合,提高思政教育及时性以及促进大学生的自我教育均具有重大意义。     

构建高校基层党组织回应机制的必要性与路径

构建高校基层党组织回应机制是培育新一代大学生党员、探索高校基层党建模式、不断丰富马克思主义执政党建设理论的需要。当前,构建高校基层党组织回应机制的制约因素主要是:回应动力不足、回应渠道不畅通与回应载体缺乏创新。为此,需要建立制度化的互动模式、畅通回应渠道、推进回应载体信息化建设。     

孤独症谱系障碍儿童呼名反应和应答性微笑的影响因素研究

呼名反应（Response to name）需要被呼叫的儿童识别并将注意转移到自己的名字这一具有社会意义的刺激上。前人研 究对于孤独症儿童是否存在呼名反应缺陷尚不完全清楚。笔者在本研究中主要采用家庭录像法考察孤独症儿童的呼名反应, 同时考察儿童在呼名反应之后的应答性微笑,共收集46名孤独症儿童的视频资料。结果表明,59.1%的孤独症儿童表现出呼 名反应,但是仅有28.3%的儿童在被呼名后出现应答性微笑。影响呼名反应和应答性微笑的情境因素包括主要活动、交往对 象和互动媒介等。总之,孤独症儿童应答性微笑非常困难。该指标更具有敏感性,可作为孤独症早期的筛查指标之一。     

Dose‐Response Models Incorporating Aerosol Size Dependency for Francisella tularensis

The effect of bioaerosol size was incorporated into predictive dose‐response models for the effects of inhaled aerosols of Francisella tularensis (the causative agent of tularemia) on rhesus monkeys and guinea pigs with bioaerosol diameters ranging between 1.0 and 24 μm. Aerosol‐size‐dependent models were formulated as modification of the exponential and β‐Poisson dose‐response models and model parameters were estimated using maximum likelihood methods and multiple data sets of quantal dose‐response data for which aerosol sizes of inhaled doses were known. Analysis of F. tularensis dose‐response data was best fit by an exponential dose‐response model with a power function including the particle diameter size substituting for the rate parameter k scaling the applied dose. There were differences in the pathogen's aerosol‐size‐dependence equation and models that better represent the observed dose‐response results than the estimate derived from applying the model developed by the International Commission on Radiological Protection (ICRP, 1994) that relies on differential regional lung deposition for human particle exposure.     

Treatment Choice With Trial Data: Statistical Decision Theory Should Supplant Hypothesis Testing

Abstract

A central objective of empirical research on treatment response is to inform treatment choice. Unfortunately, researchers commonly use concepts of statistical inference whose foundations are distant from the problem of treatment choice. It has been particularly common to use hypothesis tests to compare treatments. Wald’s development of statistical decision theory provides a coherent frequentist framework for use of sample data on treatment response to make treatment decisions. A body of recent research applies statistical decision theory to characterize uniformly satisfactory treatment choices, in the sense of maximum loss relative to optimal decisions (also known as maximum regret). This article describes the basic ideas and findings, which provide an appealing practical alternative to use of hypothesis tests. For simplicity, the article focuses on medical treatment with evidence from classical randomized clinical trials. The ideas apply generally, encompassing use of observational data and treatment choice in nonmedical contexts.     

Humanitarian response and stress in Kenya: gendered problems and their implications

ABSTRACT

Stress-related conditions such as burnout and post-traumatic stress disorder are a growing concern in the humanitarian sector. Aid workers themselves report not only that mental health problems are common, but that the support they receive from their employers is insufficient. Problematically, the experience of the international aid worker – particularly those who are white and from the global North – is often foregrounded in explaining what constitutes stress and related mental health problems. This indicates a wider problem of what is required of ‘the perfect humanitarian’ – a personality that is gendered and racialised – and how this influences the different experiences and treatment of national and international staff from aid agencies. This article explores the organisational culture and working conditions of humanitarian settings and their impact on the mental health and well-being of staff. It argues that there is a structural dimension to stress that is less to do with external security threats and more to do with the specific infrastructure, policies, and practices of humanitarian operations, with implications for aid workers which cut across dimensions of race, gender, and nationality.
