Paradigm of ‘better life’: ‘development’ among the Khumi in the Chittagong Hill Tracts

Development is conventionally understood in various ways including economic growth, increase of gross domestic product (GDP), rise of per-capita income, improvement of social facilities, political stabilities, and women's empowerment and many other issues, but it finally means bringing positive changes in the life of people. However, development is always contextual because the notion and nature of development often varies from society to society depending on the context of local–societal dynamics. Therefore what is regarded globally accepted model of development can be challenged by the local discourse of development, since local-level perception could contest the universal model. This article addresses such a case of development which is conceptualised from the social and cultural point of view amid everyday experiences of ordinary people's lives. The article contextualises its argument with specific reference to the Khumi people living in the Chittagong Hill Tracts of Bangladesh.     

Effect of a new selection procedure on adaptive estimation

Adaptive estimation of parameters of some failure time distributionsis considered. A new procedure named the F-procedure has beendeveloped for selecting an appropriate model out of two possible models by Pandey et.al. (1991). Applying this F-procedure adaptive estimatorsof parameters of exponential, Wei bull, inverse Gaussian (IG) and Wald failure time distributions have been proposed in this paper. Comparison of these estimators has been undertaken with MLE's of the respective parameters and with some previous adaptiveestimators by simulation of samples using the Monte Carlo method.Adaptive estimation of parameters of some failure time distributions is considered.

Does Cultural Difference Affect Investment–Cash Flow Sensitivity? Evidence from OECD Countries

We investigate the influence of national culture on corporate investment–cash flow sensitivity. We conjecture that national culture shapes managerial perceptions of information asymmetry and agency problems, thus impacting the investment–cash flow relationship. We document empirical evidence in support of our claim. By linking the investment–cash flow sensitivity to cultural differences, our findings show that, while collectivism has an attenuating influence, uncertainty avoidance, power distance and masculinity have a reinforcing effect on the relationship between cash flow and investment. Our results hold for a sample of 205,268 firm‐years across 24 OECD countries between 1990 and 2017, and are robust after accounting for alternative statistical approaches, sample compositions and measures of cultural dimensions, along with controls for institutional and governmental factors. In addition, by decomposing cash flow into uses and sources of funds in a dynamic multi‐equation model, where firms make financing and investment decisions jointly subject to the constraint that sources must equal uses of cash, we find that national culture shapes how firms react to changes in cash flow.     

Testing equality of two normal means using combined samples of paired and unpaired data

A test for equality of two normal means when the data consist of both paired and unpaired observations is proposed. The proposed test is compared with two other standard methods known in the literature with respect to the type I error rate and power using simulation results.     

Living on the margin: the positioning of the ‘Khumi’ within the sociopolitical and ethnic history of the Chittagong Hill Tracts

The Chittagong Hill Tracts (CHT) of Bangladesh has long been represented as a region of multi-ethnic setting, ethnic conflict and ethnic movement in South Asia. However, inter-ethnic relationship through the practice of unequal power and positions among the ‘Pahari’ (hill-people), the inhabitants of the CHT, has largely been ignored in the deeper understanding of the CHT. In addition, available CHT literature talks mostly about numerically dominant ethnic groups, whereas less attention is paid to the marginalized ‘Pahari’ ethnic groups. This paper examines the positioning of the ‘Khumi’, one of marginalized Pahari ethnic groups, within the larger canvas of CHT vs state across times and regimes. In an attempt to identify the position of the Khumi within the sociopolitical and ethnic history of the CHT, it seeks answers to three central questions: (a) How did the Khumi appear in the demographic configuration of the CHT? (b) How had they, along with the CHT and its other inhabitants, been dealt with during the colonial and postcolonial regimes? (c) How do they position themselves in the recurrent sociopolitical dynamics of CHT vs state relationship? The paper is based on critical consideration of secondary sources on the region in collaboration with relevant comprehensive data collected through ethnographic fieldwork undertaken from November 2005 to April 2007 in the CHT of Bangladesh.     

Optimal partially balanced nested row-column designs

A partially balanced nested row-column design, referred to as PBNRC, is defined as an arrangement of v treatments in b p × q blocks for which, with the convention that p q, the information matrix for the estimation of treatment parameters is equal to that of the column component design which is itself a partially balanced incomplete block design. In this paper, previously known optimal incomplete block designs, and row-column and nested row-column designs are utilized to develop some methods of constructing optimal PBNRC designs. In particular, it is shown that an optimal group divisible PBNRC design for v = mn kn treatments in p × q blocks can be constructed whenever a balanced incomplete block design for m treatments in blocks of size k each and a group divisible PBNRC design for kn treatments in p × q blocks exist. A simple sufficient condition is given under which a group divisible PBNRC is Ψ_f-better for all f> 0 than the corresponding balanced nested row-column designs having binary blocks. It is also shown that the construction techniques developed particularly for group divisible designs can be generalized to obtain PBNRC designs based on rectangular association schemes.     

Attachment Relationships and Psychological Adjustment of Married Adults

The present study explored relations among remembered parental (paternal and maternal) acceptance in childhood, spouse acceptance and psychological adjustment of adults. It also explored whether remembered childhood experiences of parental acceptance mediate the relation between perceived spouse acceptance and psychological adjustment. The sample consisted of 354 married adult men (178) and women (176). Results showed that the more accepting both men and women perceived their spouses to be, the better was their psychological adjustment. Similarly, the more accepting both men and women remembered their parents had been to them during childhood, the better was their psychological adjustment. Standard multiple regression analyses revealed that paternal acceptance mediated the relation between perceived spouse acceptance and the psychological adjustment of both men and women. In addition, remembered maternal acceptance mediated the relation between men’s (but not women’s) perceived spouse acceptance and psychological adjustment.     

Systemic Consultation in Intellectual Disability Case Management

Systemic consultation is a form of tertiary case supervision derived from the principles of systemic family therapy. The present study defines the process and outcomes of systemic consultation through the experiences of case managers (CMs) working with people who have an intellectual disability. CMs were invited to present and discuss one of their complex cases with a team of consultants and attend a follow up session 4 to 6 weeks later. Measures of levels of stress, perception of workplace functioning, and workflow information were completed pre and post‐intervention and compared to measures completed by a second group of CMs receiving regular supervision only. After participation in systemic consultation, the networks of people CMs consulted about the case were significantly smaller and they scored significantly higher on a network measure of efficiency of information flow. The CMs experienced lower levels of stress and higher perception of workplace functioning, these differences approached significance. After attending the consultation outcome, themes included a reduced sense of being stuck and stressed, becoming an agent of change and taking perspective. The approach allows CMs space for reflection on practice and new perspectives to be heard. Case management has been under‐represented in documented research and evidence‐based training and supervision models, and is an area in which professional theory appears to be lacking.     

Optimal block designs for three treatments when observations are correlated

E$E$-optimal designs for comparing three treatments in blocks of size three are identified, where intrablock observations are correlated according to a first order autoregressive error process with parameter ρ∈(0,1)$\rho \in (0,1)$. For number of blocks b   of the form b=3n+1$b=3n+1$, there are two distinct optimal designs depending on the value of ρ$\rho$, with the best design being unequally replicated for large ρ$\rho$. For other values of b$b$, binary, equireplicate designs with specified within-block assignment patterns are best. In many cases, the stronger majorization optimality is established.     

THE ROBUSTNESS OF BINARY AND NON-BINARY BALANCED NESTED ROW-COLUMN DESIGNS UNDER THE UNAVAILABILITY OF BLOCKS: A COMPARISON

In cases where both exist, the balanced, binary nested row-column designs are known to be inferior to a class of balanced non-binary designs. However, if it is possible for blocks of observations to become unavailable after an experiment has commenced, a binary nested row-column design may possibly be better than a non-binary one. This paper investigates the robustness of binary and non-binary variance-balanced nested row-column designs to the unavailability of one or more blocks of observations. Robustness is measured through the C-matrices of the designs resulting from removing blocks, using optimality criteria such as A-, D-, E- and MV-optimality.
