Burnout and life satisfaction: does gratitude intervention make a difference among Chinese school teachers in Hong Kong?

This study investigated the effectiveness of a gratitude intervention programme in promoting life satisfaction and reducing burnout symptoms. Sixty-three Hong Kong Chinese school teachers aged 22–54 participated in an eight-week count-your-blessings study that used a pre-test/post-test design. Increases in life satisfaction and the sense of personal accomplishment and decreases in emotional exhaustion and depersonalisation were observed in the post-intervention assessment. Significant changes were observed on life satisfaction and emotional exhaustion as a result of intervention interacting with the meaningful-life orientation to happiness. These changes favoured teachers who put higher value on the meaningful-life orientation, suggesting that the promotion of a meaningful-life orientation could be an important element in the repertoire of gratitude intervention efforts. Implications of the findings on developing gratitude intervention programmes that focus on human positives and the promotion of gratitude and the meaningful-life orientation in combating teacher burnout are discussed.     

Partially Identified Treatment Effects for Generalizability

Recent methods to improve generalizations from nonrandom samples typically invoke assumptions such as the strong ignorability of sample selection, which is challenging to meet in practice. Although researchers acknowledge the difficulty in meeting this assumption, point estimates are still provided and used without considering alternative assumptions. We compare the point identifying assumption of strong ignorability of sample selection with two alternative assumptions—bounded sample variation and monotone treatment response—that partially identify the parameter of interest, yielding interval estimates. Additionally, we explore the role that population data frames play in contributing identifying power for the interval estimates. We situate the comparison around causal generalization with nonrandom samples by applying the assumptions to a cluster randomized trial in education. Bounds on the population average treatment effect are derived under the alternative assumptions and the case when no assumptions are made on the data. While comparing the bounds, we discuss the plausibility of each alternative assumption and the practical trade-offs. We highlight the importance of thoughtfully considering the role that assumptions play in causal generalization by illustrating the differences in inferences from different assumptions.

Research: Korean International Students' Expectations About Counseling

This study examined the counseling expectancies of Korean international students in the United States. The results indicated that Korean students expected to terminate counseling quickly if the process was viewed as unpleasant or did not seem to be immediately helpful. The Korean students expected to approach counseling as a classroom learning situation in which they could present problems, ask questions about the problems, and work on assignments to solve the problems. Implications for outreaching and counseling Korean international students are discussed.     

IEEE 802.11无线网状网中的一种干扰感知的多径路由协议

基于IEEE 802.11 MAC层协议模型,提出一种新颖的能够描述多条路径之间干扰程度的多径路由判据IAMM,并以此为基础,提出一种新的干扰感知的多径路由IAMR协议.IAMR协议通过2次选路,在保证单条路径性能的同时兼顾考虑路径之间的干扰因素.仿真实验表明,IAMR协议在端到端延迟、数据包到达率和吞吐量等方面均有较明显的性能提升.
