Income vulnerability of rural households in Bangladesh: a comparison between Bayesian and classical methods

The geographical location and the monsoon climate render Bangladesh highly vulnerable to natural hazards, deteriorating the country's socio-economic stability. This study is based on 500 randomly chosen rural households from the Household Income and Expenditure Survey [Bangladesh Bureau of Statistics, Planning Division, Ministry of Planning, Government of the People's Republic of Bangladesh, Dhaka, 2006]. The objectives are to estimate the income vulnerability of rural households and to check whether the Bayesian approaches (natural conjugate prior and non-informative prior estimates) have any superiority over the classical (feasible generalized least square (FGLS)) method. The poverty level, measured from the data, is 24%; whereas the vulnerability estimates, using FGLS, natural conjugate prior and non-informative prior are 31%, 69% and 82%, respectively. Vulnerability estimates by the Bayesian natural conjugate prior approach is found to have greater efficiency compared with FGLS and non-informative prior approaches.     

Child Rights Practice among the Indigenous Communities in Bangladesh

The objective of this article was to explore the practice of child rights among the indigenous communities of Bangladesh. We used a mixed method approach to collect data from four ethnic communities in the Bandarban District of the Chittagong Division in Bangladesh. We questioned children, parents, community members, local leaders, and service providers of those communities on a number of child rights issues, for example, child education, child labor, child recreation and culture, parents' guidance to children for capacity development, and access to child rights at home and in the community according to Convention on the Rights of the Child treaty. The results showed that while the community was aware of child rights, financial vulnerability and a lack of social support meant that these rights could not be upheld in practice. The paper urges improvement of social support, including income generation activities for indigenous communities.     

Implementation of Child Rights in the Children's Homes in Malaysia

The objective of this study was to examine the implementation of the Convention on the Rights of the Child (CRC) in the Children Homes under the Social Welfare Department (SWD) in Malaysia. Data was collected from 402 registered children who were staying in six Children Homes across the country. This study employed self‐report surveys where multiple data collection methods, such as face‐to‐face structured interviews, key informant interviews (KIIs), and documentation survey, were used. The study found that the SWD failed to comply with most of the commitments of CRC in Children Homes at its implementation level, and it is still needs based. The findings of this study present important guidelines for government and policy makers in improving child welfare services in the Children Homes in Malaysia.     

Hunger Reduction in China: An Analysis of Contextual Factors

In recent times, China has significantly reduced hunger in its populace. The main objective of this paper was to analyze some of the contextual socioeconomic factors contributing to the reduction of hunger in China, using Qualitative Interpretative Meta‐Synthesis (QIMS). The results revealed that China has followed a broad‐based and multispectral approach to reduce hunger. Factors, such as poverty alleviation; social safety nets for disadvantaged villagers; agricultural development and land reforms; regional development and equity in development activities; infrastructural development; and political‐economic reform and sustainable growth were influential in reducing hunger in China. Poverty is attributed as one of the principal contributors and is interlinked with many other dimensions. The findings of this paper are a useful guide to the Chinese government, policy‐makers, international organizations, and development practitioners.     

Prediction of disease status: A regressive model approach for repeated measures

In this paper, regressive models are proposed for modeling a sequence of transitions in longitudinal data. These models are employed to predict the future status of the outcome variable of the individuals on the basis of their underlying background characteristics or risk factors. The estimation of parameters and also estimates of conditional and unconditional probabilities are shown for repeated measures. The goodness of fit tests are extended in this paper on the basis of the deviance and the Hosmer–Lemeshow procedures and generalized to repeated measures. In addition, to measure the suitability of the proposed models for predicting the disease status, we have extended the ROC curve approach to repeated measures. The procedure is shown for the conditional models for any order as well as for the unconditional model, to predict the outcome at the end of the study. The test procedures are also suggested. For testing the differences between areas under the ROC curves in subsequent follow-ups, two different test procedures are employed, one of which is based on permutation test. In this paper, an unconditional model is proposed on the basis of conditional models for the disease progression of depression among the elderly population in the USA on the basis of the Health and Retirement Survey data collected longitudinally. The illustration shows that the disease progression observed conditionally can be employed to predict the outcome and the role of selected variables and the previous outcomes can be utilized for predictive purposes. The results show that the percentage of correct predictions of a disease is quite high and the measures of sensitivity and specificity are also reasonably impressive. The extended measures of area under the ROC curve show that the models provide a reasonably good fit in terms of predicting the disease status during a long period of time. This procedure will have extensive applications in the field of longitudinal data analysis where the objective is to obtain estimates of unconditional probabilities on the basis of series of conditional transitional models.     

Reflection note: confessions of a Muslim researcher – considering identity in research

ABSTRACT

This research note explores some of the contentions that have emerged from Muslim-on-Muslim research and how this can implicate the researcher more personally. Speaking in the context of methodological concerns arising from qualitative research, the paper consider the following aspects: inappropriate access of participants, over-representation of own experiences, and questioning fundamental parts of your identity. Whilst certain experiences can shake the foundations of being a researcher and even sense of self, these should ultimately be welcomed. It is concluded that, in taking the time to reconcile from such tensions emerging from our multiple identities, it can allow for becoming a more rigorous and reflexive researcher.     

A study of some ridge-type shrinkage estimators

In this paper,several ridge-type shrinkage estimators are studied with respect to their relative efficiency. Some interrelationships which exist among these estimators are pointed out. One of these estimators, T∞ based on the work of Mehta and Srinivasan (1971), is shown to be a flexible estimator, which has clear advantages over its competitors. A useful approximation for calculation of the relative efficiency of T∞ is also presented.     

Improving Development Ownership Among Vulnerable People: Challenges of NGOs’ Community Empowerment Projects in Bangladesh

This paper exposed the major challenges that the non‐governmental organizations (NGOs) face in improving development ownership among vulnerable people in community empowerment projects in Bangladesh. The finding, based on a qualitative research approach, used multi‐method data collection procedures. Data were collected from two NGOs, Proshika and Practical Action Bangladesh (PAB), working with two vulnerable communities—blacksmiths and goldsmiths. The results showed that NGOs faced a number of challenges, including lack of understanding about the local context, initiatives to localize global development tools, developing partnership, and space for local people in the development processes. The paper argued that, without securing development ownership, the NGOs’ activities toward community empowerment of vulnerable people would not be possible. The findings of the paper would be valuable guidelines for policy makers, development practitioners, NGO workers, and academicians.     

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.
