化学实验室内可吸入颗粒物的实时测量与分析

实验采用智能大气综合采样器采集有机实验室和环境实验室大气中的可吸入颗粒物（PM10），对PM10进行了全天不同时段的跟踪测量。初步实验结果表明：有机实验室内PM10质量浓度明显高于环境实验室内PM10质量浓度，主要是使用强挥发性物质和实验室通风不畅所致。不同实验室不同时段差别巨大，最高时段可达1．13mg／m^3，初步检测颗粒物中附有多环芳烃类物质，对人体的潜在危害不客忽视。     

Dimensions of effective CSR communication based on public expectations

Through surveying a representative sample of the general public about what they expect from companies’ corporate social responsibility (CSR) communication, this study empirically examines predictors to evaluate CSR communication. An initial measurement was identified through an exploratory factor analysis, and the initial measurement model was refined via a confirmatory factor analyses. The study identified six essential CSR communication dimensions: (1) informativeness, (2) third-party endorsement, (3) personal relevance, (4) message tone, (5) consistency, and (6) transparency. These six constructs revealed satisfactory reliability, discriminant validity, and convergent validity. The findings offer an integrated theoretical and methodological basis for evaluating effective CSR communication practice, filling an important missing link between CSR activities and their outcomes.

我国旅游服务贸易的竞争优势分析——基于“钻石模型”

旅游服务贸易是我国服务贸易中总量最大的项目,对增加外汇收入、拉动经济增长有重要作用。我国的旅游服务贸易经过三十多年的发展取得了显著的成就,但与发达国家相比仍存在显著的差距。基于迈克尔.波特的"钻石模型",从生产要素、需求情况、相关和支撑产业,以及企业的战略、结构与竞争四个基本要素和机遇、政府两个辅助要素分析我国旅游服务贸易的竞争优势,提出发展对策:加强政府的主导作用;提升旅游企业的竞争力;发展旅游的相关产业;培养高素质的专业人才。     

公允价值计量:一个世界性的财务报告难题

公允价值计量是一个公认的世界性财务报告难题,"定义"和"计量级次"是该难题的症结所在。我们分析了IASB与FASB为改进公允价值定义和计量级次所做的尝试和所取得的成果,它们的经验对完善我国新准则公允价值计量应用有借鉴作用。     

影响农民收入的相关因素分析

影响农民收入增长的因素是复杂而多变的,这些相关因素既可能表现为正相关又可能表现为负相关,这表明政府的相关政策可能存在失效或失灵的问题。在推进社会主义新农村建设时期找准影响农民收入的因素以便对症下药,更是一个重大而现实的问题。本文认为,在影响农民收入的诸多因素中,制度、组织、契约、教育、科技这五大因素对农民收入的增长具有直接而长期的决定作用,但作用的发挥需要党和政府一系列供给措施的落实。

A Causal Relationship Between the Balanced Scorecard Perspectives

Abstract

An increasing number of hotel organizations endeavor to achieve long-term competitive advantages in the marketplace through the implementation of strategic performance measurement systems. These systems are designed to integrate and monitor strategic objectives throughout the business processes. This paper investigates the causal relationships between the strategic performance measures of hotel organizations, using The Balanced Scorecard (BSC) framework. This comparative study illustrates how hotel organizations plan, improve and monitor their strategic performance targets through the use of comprehensive performance measurement systems. The paper also recommends specific approaches for the implementation of the BSC for hotel organizations.     

Modelling Strategies for Repeated Multiple Response Data

This article discusses modelling strategies for repeated measurements of multiple response variables. Such data arise in the context of categorical variables where one can select more than one of the categories as the response. We consider each of the multiple responses as a binary outcome and use a marginal (or population‐averaged) modelling approach to analyse its means. Generalized estimating equations are used to account for different correlation structures, both over time and between items. We also discuss an alternative approach using a generalized linear mixed model with conditional interpretations. We illustrate the methods using data from a panel study in Australia called the Household, Income, and Labour Dynamics Survey.
