Gender Bias in Parental Attitude: An Experimental Approach

Parental bias toward children of a particular gender has been widely observed in many societies. Such bias could be due to pure gender preference or differences in earning opportunities and concern for old-age support. We conduct a high-stakes allocation task (subjects allocate the equivalent of one day’s wages between male and female school-aged students) in rural Bangladesh to examine parental attitudes toward male and female children. Parents, either jointly or individually, allocated freely or restricted endowments for the benefit of anonymous girls or boys at a nearby school. We examine whether there is any systematic bias among fathers and mothers and, if so, whether such bias differs when they make the decision individually or jointly. The results suggest (1) bias both for and against boys or girls but no systematic bias by either parent; and (2) no significant differences in individual and joint decisions.

Assessing recall bias and measurement error in high-frequency social data collection for human-environment research

Population and Environment - A major impediment to understanding human-environment interactions is that data on social systems are not collected in a way that is easily comparable to natural...     

Patient-specific dose finding in phase I clinical trials

This article proposes an extension of the continual reassessment method to determine the maximum tolerated dose (MTD) in the presence of patients' heterogeneity in phase I clinical trials. To start with a simple case, we consider the covariate as a binary variable representing two groups of patients. A logistic regression model is used to establish the dose–response relationship and the design is based on the Bayesian framework. Simulation studies for six plausible dose–response scenarios show that the proposed design is likely to determine the MTD more accurately than the design that does not take covariate into consideration.     

Migrant Domestic Workers in Asia: Transnational Variations and Policy Concerns

The labour force of the migrant domestic workers (MDWs) has become one of the significant policy concerns in Asia. Most of the Asian countries are not following (or not to an equal extent) the Domestic Workers Convention 2011 (No. 189) which has been adopted by the International Labour Organization (ILO). The objective of this article is to show the transnational variations and policy concerns of the MDWs in Asia. Based on content analysis, the authors found that there are considerable transnational variations of the MDWs in terms of their age and nature of work, legal identity, working hours, and remuneration across Asian countries. These variations have serious policy concerns in a number of areas such as lack of available data of the MDWs, working conditions, exploitations, and gender issues. The findings of the article would be an important guideline for adopting new legislation and labour policy for the MDWs in Asia.     

Multistate survival models for transitions and reverse transitions: an application to contraceptive use data

This paper extends the use of the multistate proportional hazards model proposed by R. Kay for transitions, reverse transitions, and repeated transitions. A simple method of testing the equality of vectors of parameters for transitions and repeated transitions is also shown in addition to estimates for the underlying cumulative hazards for different types of transition. The multistate survival models applied to contraceptive use data collected by the International Center for Diarrheal Disease Research, Bangladesh, for the period January 1978 to December 1982 provide useful findings relating to interstate transitions. The author stresses the need to not treat separately states of contraceptive use given their link to the acceptance of the first method, transitions from one method to another, first method discontinuation, periods of non-use, the use of subsequent methods, loss to follow-up, the use of irreversible methods, and subsequent periods of non-use. Religion is an important indicator for the acceptance of an irreversible method as a first or subsequent method; compared to women of other religions, Muslims were less likely to accept an irreversible method as a first or subsequent method. Religion is not, however, associated with the acceptance or subsequent use of a reversible method or with discontinuation of a reversible method. Higher age in the study area is associated with both lower acceptance and longer continuation of a method. Women with a larger number of living sons tend to accept their first method and subsequent methods at an higher rate than women with fewer or no sons. As for educational status, women with higher education proved to be serious users of contraception, although women with less or no education tend to accept an irreversible method at an higher rate than the women with an higher level of education. Further, the desire for more children is a strong predictor for non-use of a method even if contraception is used to space births. The score test suggested in the paper for testing the equality of parameters in models 1-4 reveals that there is no significant difference in the parameters of the models. This paper shows that the factors which affect the acceptance of any reversible method of contraception are different from those for an irreversible method. Moreover, the factors which affect a transition differ from those for a reverse transition in the case of adopting reversible methods.
