Inferences on regression coefficients in a regression model under heteroscedasticity and robustness with respect to departure from normality

In this paper we consider a simple linear regression model under heteroscedasticity and nonnormality. A statistical test for testing the regression coefficient is then derived by assuming normality for the random disturbances and by applying Welch's method. Some Monte Carlo studies are generated for assessing robustness of this test. By combining Tiku's robust procedure with the new test, a robust but more powerful test is developed.     

从美国金融危机看金融安全问题

美国金融危机始于2007年夏季，之后迅速蔓延到世界各主要经济体，对各国金融安全和全球经济发展带来了威胁和挑战。为了维护金融的安全与稳定，各国不但要提高对金融安全问题的重视程度、增强对金融创新风险防范的能力、完善金融监管体系，还要加强国际区域金融合作，并为构建新型的国际金融体系作出不懈努力。

劳动关系的社会控制与政府角色

法律是政府实现社会控制和社会工程的措施之一。《劳动合同法》对政府在劳动关系调整中的角色进行了强化,尤其是凸显了政府运用法律去开展社会工程和推动社会发展的作用。政府从以往对劳动关系变化的单纯应对,发展为对劳动关系和社会发展进行系统的导向。     

Older Drivers Retiring From the Road: An Application of the Selection,Optimization, and Compensation Model

Purpose: This study uses the selection, optimization, and compensation (SOC) model to compare older adults who have given up driving, those who still drive, and those who drive less to identify differences in the three groups. Design and Methods: This cross-sectional study of 281 older adults is part of the Naturally Occurring Retirement Community Demonstration Project. Study participants completed interviews that included questions on demographics, health and functioning, mental health, social support, and current levels of engagement in activities including current driving status. Results: Data suggest that driving retirement is a process and that a substantial number of people are in the transitional stage, where they are less functional than those who still drive and more similar to those who have retired from the road. Implications: Given the similarity of those who drive less to those who have given up driving, front-line professionals and policy makers must work together to ease the transition to driving retirement for those without adequate ability to effectively compensate for their inability to continue to drive safely.     

Generalized Trust and Trust in Institutions in Confucian Asia

This study examines generalized trust and trust in institutions in Confucian Asia, covering six countries namely, China, Japan, Singapore, South Korea, Taiwan and Vietnam, and one dependent region, Hong Kong. Using data from the 2006 AsiaBarometer Survey, our study affirms the reliability and validity of using a two-item scale to measure generalized trust. Our analysis suggests that due to demographic differences, there are variations in the level of generalized trust of countries in Confucian Asia, despite the fact that these societies share a similar background in Confucian philosophy. The relationships between generalized trust and political trust, and between generalized trust and trust in public institutions, are weak but positive. The positive relationship between generalized trust and trust in economic institutions is only significant for some of the economies, while trust in international institutions has the weakest relationship with generalized trust for all societies. We conclude the paper with research implications.     

《道德经》文本研究视阈下大学生道德情怀教育

改革开放以来,大学生道德教育成果显著,但道德教育活动依旧有巨大的提升空间。近年来,伴随着经济高速发展,各种社会负面信息一次次冲击大学生道德心理,大学生道德教育也变得有些吃力,因此,大学生道德教育急需回归本真。现如今是讲求情怀的年代,大学生道德情怀教育理应走进高校,结合《道德经》经典名著,讲习道德情怀含义、描述道德情怀形态、分析道德情怀教育着力点、提出道德情怀教育要求,应该成为改革开放新时期大学生道德教育研究的众多范畴之一。     

A framework for food supply chain digitalization: lessons from Thailand

Abstract

The promise of digitalization is enormous and nowhere is it more critical than in its potential to transform food supply chain. Consumers have become more educated and are demanding real-time updated information on foods they consumed through digital media. They are also increasingly demanding to know if the foods they consume are environmentally and socially sustainable or not. As a result, food product traceability, safety, and sustainability issues have become crucial concerns to food retailers, distributors, processors, and farmers. Digitalization allows food supply chains to be highly connected, efficient, and responsive to customer needs and regulation requirements. However, digitalizing a traditional food supply chain is challenging and resource demanding. This is more so for developing countries where moving food from farms to consumers can take months as it travels through an array of middlemen. Unfortunately, little is available in the existing literature on food supply chain digitalization. So far, current researchers mainly explore the benefits of digitalization. Using cases in three companies, this paper explores the practices, challenges, and opportunities faced by Thailand food manufacturers in digitalizing their food supply chains. A framework for food supply chain digitalization is proposed and its implications for research and practices are discussed.
