Estimating unmet need for contraception by district within Ghana: an application of small-area estimation techniques

The importance of meeting the unmet need for contraception is nowhere more urgent than in the countries of sub-Saharan Africa, where the fertility decline is stalling and total unmet need exceeds 30 per cent among married women. In Ghana, where fertility levels vary considerably, demographic information at sub-national level is essential for building effective family planning programmes. We used small-area estimation techniques, linking data from the 2003 Ghana Demographic and Health Survey to the 2000 Ghana Population and Housing Census, to derive district-level estimates of contraceptive use and unmet need for contraception. The results show considerable variation between districts in contraceptive use and unmet need. The prevalence of contraceptive use varies from 4.1 to 41.7 per cent, while that of the use of modern methods varies from 4.0 to 34.8 per cent. The findings identify districts where family planning programmes need to be strengthened.     

政策调整适应劳动力市场灵活性

20世纪90年代以来,是中国从计划经济向市场经济转轨、市场经济体制逐步形成的过程。在这一过程中,政府对市场的直接干预程度弱化,劳动力市场机制对资源配置的基础性作用不断增强。与此同时,劳动立法和执法工作滞后,导致正规就业岗位越来越少,灵活就业和非正规就业比重极大增加,工作任期普遍缩短,劳动力流动率提高,而社会保障、就业服务机会不足,劳动者就业的稳定感极大地降低,劳动力市场的总体就业安全性降低。在这一过程中,政府进行了一系列的立法、制度和政策调整,来适应不断增强的就业灵活性。本文主要从劳动力市场制度政策的角度,对这些调整进行评价,并提出建议。     

A Cultural-Psychological Theory of Contemporary Islamic Martyrdom

What political, economic, religious, and emotional factors are involved in a person's decision to kill civilians and military personnel through the sacrifice of his or her own life? Data for this research were secondary analyses of interviews with Islamic martyrs, as well as their leaders’ speeches. This investigation into the cultural‐psychological explanations for Islamic martyrdom leads to a model explaining a person's decision to carry out the mission as resulting from a combination of four factors: the historical‐cultural context, group processes, immediate and anticipated rewards, and mechanisms to eradicate possible doubts and guilt regarding this decision. Compared to existing models, this model is more integrative and focused on the psychological processes involved.     

Operational research in Indian defence

The paper gives an outline of the areas of Operational Research (OR) where work in the Defence Department in India has been successful, even though it has not been fully implemented due to certain reservations on the part of the users and some limitations of OR scientists. There is an ad hoc quality in the decision making of the customer, and no large scale OR models are available which give a total effect of defence spending on social measures and human resources development. OR would be able to contribute to a balanced spending on defence in developing countries, if effort were made to analyse defence problems in the wider context. The author was formerly Director of Scientific Evaluation, Ministry of Defence, India.     

Use of a case study in sequencing/scheduling research

This paper describes a study of an industrial sequencing/scheduling problem. The study contains the definition of the problem, data requirements and examination of solution technique. Definition of the problem is discussed from the aspect of uniqueness of the specific system. Discussion of data requirements includes availability and accuracy, while examination of solution technique considers limitation of time, computer capacity, etc., as well as the possibility of imbedding available algorithms into the solution procedure. Conclusions are presented relative to the use of the case study approach in sequencing/scheduling research.     

Baghdadi Jews in Hong Kong: converting cultural,social and economic capital among three transregional networks

This article is an analysis of the attempts of Baghdadi Jewish traders in Hong Kong in the second half of the nineteenth century to construct and convert cultural, social and economic capital within and between the transregional networks of the Baghdadi diaspora, the Jewish diaspora and the British colonial elite. The analysis of the multiple and multi‐directional intersections between the cultural, social and economic characteristics of the three networks shows that Baghdadi social capital accounted for significant ruptures and disjunctures between the increasing cosmopolitanization, deterritorialization and hybridization of the Baghdadi traders' cultural identities and the definition of Baghdadi cultural capital. An understanding of the role of Baghdadi social capital in accounting for the construction and convertibility of cultural, social and economic capital among these three transregional networks helps to explain the reproduction of social inequalities under increasing conditions of globalization, that is, under conditions that potentially augmented the number of sources defining cultural capital.     

A comparison of simple score and latent class approaches: application to HIV knowledge data in Chinese and multi-country contexts

Knowledge about different health-related attitudes, beliefs, and risks is of significant interest to scholars in different Social Science disciplines. Usually knowledge is collected in a form of multiple variables and then constructed as a composite indicator. The question any researcher working with knowledge-related variables faces is: what is the best way to measure and summarise different dimensions of health-related knowledge? The main goal of this paper is to evaluate and compare simple score and latent class approaches to measuring and summarising health-related knowledge using population data on HIV knowledge collected in five selected countries (China, India, Kenya, Malawi, and Ukraine). The advantages and shortcomings of both approaches (simple score and latent class approaches) to measuring and summarising health-related knowledge are evaluated and discussed.
