Do Demographic Characteristics Make a Difference to Burnout among Hong Kong Secondary School Teachers?

This study aims to investigate the relationship between teachers demographic variables and burnout in Hong Kong using the Maslach Burnout Inventory. It is found that when compared with the North American normative data, Hong Kong teachers scored in the average range of burnout in emotional exhaustion and personal accomplishment while they scored in the low range of burnout in depersonalization. Gender differences were found in all three burnout syndromes, and teachers who were younger, unmarried, without religious beliefs, less experienced, without finishing professional training and of junior rank were more consistently burned out. Whereas age was the strongest predictor for emotional exhaustion and depersonalization, teachers rank is the best predictor for personal accomplishment. However, the effect of demographic characteristics of teachers on burnout is not that salient.     

Case report: a work simulation program for a manual worker with a fracture injury

Work rehabilitation programs targeting different client groups are available in nearly all major hospital occupational therapy departments in Hong Kong. Clients receiving work rehabilitation are referred from various out-patient clinics and other occupational therapists. Those clients experience limitation in work after their injuries or diseases and plan to return to work after rehabilitation. Program objectives are 1) to assist clients to reach maximum work capacity as rapidly as possible 2) to ensure clients return to work safely 3) to improve clients' work readiness. This case report describes an individualized work simulation program at a general hospital in Hong Kong provided for a typical client who is preparing to return to his worker role. Specific job analysis, goals and program rationale for the client are discussed.     

A dynamic programming approach of finding an optimal broadcast schedule in minimizing total flow time

We study the problem of (off-line) broadcast scheduling in minimizing total flow time and propose a dynamic programming approach to compute an optimal broadcast schedule. Suppose the broadcast server has k pages and the last page request arrives at time n. The optimal schedule can be computed in O(k³(n+k)^k−1) time for the case that the server has a single broadcast channel. For m channels case, i.e., the server can broadcast m different pages at a time where m < k, the optimal schedule can be computed in O(n^k−m) time when k and m are constants. Note that this broadcast scheduling problem is NP-hard when k is a variable and will take O(n^k−m+1) time when k is fixed and m ≥ 1 with the straightforward implementation of the dynamic programming approach. The preliminary version of this paper appeared in Proceedings of the 11th Annual International Computing and Combinatorics Conference as “Off-line Algorithms for Minimizing the Total Flow Time in Broadcast Scheduling”.     

The Moral "Technologies' of Knowledge Management

This paper uses the framework of Michel Foucault to examine the mainstream discourse of "knowledge management' (KM) in organizations. In particular, we draw on the notions of reflexivity, subjectivity, power, freedom and resistance to show how Foucault's ideas challenge contemporary uses of KM including its alignment with organizational learning and strategic change. A dominant theme of KM discourse relates to what computer technology can do for storing, sorting and distributing organizational knowledge. Indeed, a central assumption of the ideology of KM is that its systems are universally desirable. KM is often presented as a common-sense way of thinking about one's organization, and having everyone "pitch-in' through sharing knowledge is meant to ensure the company's commercial future. KM is thus represented as in the fundamental interests of workers and companies alike. In this article, we jettison the idea that KM is an unquestioned good. More specifically, we are concerned with the highly instrumental ways that knowledge is being constructed and how this influences workplace subjectivities. Foucauldian theory certainly helps with an examination of KM discourse, but we do not claim it is the only theory appropriate to this subject.     

医疗卫生、住房保障与居民生活满意度关系研究——基于CGSS2013数据实证分析

本文基于CGSS2013年9600位居民的调查数据,实证分析了医疗卫生、住房保障与居民生活满意度之间的逻辑关系.研究发现,医疗卫生和住房保障对居民生活满意度有显著正向影响;两者通过个体状况、社会态度和政府服务中间变量间接影响居民生活满意度的程度几乎都要大于直接影响程度;医疗卫生和住房保障服务供给的充足性、均衡性以及民众获取的便利性是影响居民生活满意度的主要因素;医疗卫生、住房保障逐步地走向市场化并逐渐被民众所接受.研究进一步表明,医疗卫生和住房保障对不同群体的居民生活满意度均有显著影响.     

Quality of Life in Older Adults: Benefits from Caring Services in Hong Kong

Many older adults are in need of care. Therefore, older people would generally benefit from the use of caring services, notably including home care, residential care, nursing, and medical services. The contributory factors underlying caring services tend to be a caring perspective that aspires to sustain older peoples social relationships and real-life involvement. To gauge the benefits from various social and health services, the present study relies on a large-scale survey of 3000 older adults in Hong Kong, using quality of life as a criterion. Results showed that an older adult who had used (ordinary or enhanced) home care services for a longer time turned out to have appreciably more improvement in quality of life. Besides, those who joined an interest group more frequently were higher in quality of life, including the health domain. On the other hand, frequent use of medical and meal-to-home services were signals that reflected problems detrimental to the older users quality of life. Despite this, the quality of clinics or hospitals, as perceived by the older adult, was the most beneficial. As such, caring services that foster older adults interests, cater to their health care needs, and embody quality can have principal contribution to their users quality of life.     

Compensating changes in fertility and mortality

This paper illustrates a method of studying changes in vital rate schedules which have no effect on the intrinsic rate of population growth. These changes are described as compensating changes in fertility and mortality. The analysis proceeds from the discrete perspective of Leslie matrices, wherein the central idea is to establish the set of all compensating changes by identifying that class of Leslie matrices which possess the same positive eigenvalue, λ₁. A root-squaring technique is adapted for the purpose of estimating λ₁. Finally, a variety of compensating fertility and mortality changes is illustrated using data from Japan.     

The Chinese version of the multidimensional orientation toward dying and death inventory (MODDI-F/chin): an introduction

Preliminary data on the test criteria of the Chinese version of the Multidimensional Orientation Toward Dying and Death Inventory (MODDI-F/chin) are presented. Data from a sample of Hong Kong college students (N = 256) revealed internal consistencies of the eight subtests between .68 and .91, on the whole favorable shape of frequency distributions, and evidence of construct as well as differential validity of the instrument. The use of the full set of 47 items is recommended for the time being.     

Online tree node assignment with resource augmentation

Given a complete binary tree of height h, the online tree node assignment problem is to serve a sequence of assignment/release requests, where an assignment request, with an integer parameter 0≤i≤h, is served by assigning a (tree) node of level (or height) i and a release request is served by releasing a specified assigned node. The node assignments have to guarantee that no node is assigned to two assignment requests unreleased, and every leaf-to-root path of the tree contains at most one assigned node. With assigned node reassignments allowed, the target of the problem is to minimize the number of assignments/reassignments, i.e., the cost, to serve the whole sequence of requests. This online tree node assignment problem is fundamental to many applications, including OVSF code assignment in WCDMA networks, buddy memory allocation and hypercube subcube allocation.
