A Selection Procedure for Selecting the Least Increasing Failure Rate Average Distribution

For k independent absolutely continuous increasing failure rate average (IFRA) life distributions F_i, i = 1, 2, …, k, Link (1989 Link, W.A. (1989). Testing for exponentiality against monotone failure rate average alternatives. Commun. Statist. Theor. Meth. 18(8): 3009–3017.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) considered a measure of departure of against monotone failure rate average alternatives. In this paper, we use the measure defined by Link for detection of IFRA-ness of life distribution F_i. A two-stage selection procedure to select the least IFRA distribution is proposed. This selection procedure is based on a U-statistic which is an estimator of the measure and can be implemented even when the IFRA life distributions belong to different families. The applications of this procedure are discussed for some well known distributions.     

Some Effective Rotation Patterns in Estimation of Population Mean in Two-Occasion Successive Sampling

This article is an attempt to explore some effective rotation patterns in estimation of current population mean in two occasions successive sampling. Utilizing the readily available information on an auxiliary variable on both occasions and the information on study variable from the previous occasion, some efficient estimation procedures have been suggested. Optimum replacement strategies and the efficiencies of the proposed estimators have been discussed. Empirical studies are carried out and suitable recommendations are made.     

m-Associate PBIB designs using Youden-m squares

In this paper, we have proposed a type of arrangement that we call Youden-m square and is similar to the usual Youden square but generates PBIB designs instead of BIB designs when its columns are taken as blocks. We have also discussed its construction methodologies, introduced two new m-associate class association schemes, and also constructed some series of Youden-m square type PBIB designs.     

Data Gap Analysis,Indicator Selection and Index Development: A Case for Developing Economies

Sustainable Development Goals (SDG) and its measurement is a key policy focus across the globe. Despite existence of several indices and reporting agencies, it is a challenging task to identify progress, specifically in the case of developing economies. These economies are predominantly in Asia and Africa and have a great bearing on global performance. These countries have diverse geographical and cultural elements with an active sub-national institutional framework. Data gap coupled with poor data quality and limited financial support does not help their case. Without appropriate indicator selection and index measurement it is not possible to judge the actual current situation or compare the SDG situation around the world. This paper attempts a practical and simpler approach to overcome the constraints, provide direction and facilitate measurement of SDG position in such countries using the case of India. This is done by identifying gaps, suggesting a tailored approach to indicator selection and measurement and further, developing a suitable index for SDG measurement at the sub-national level. The results and findings should be of great interest for policy making and implementing agencies.

The Influence of Stakeholders on the Environmental Strategy of Service Firms: The Moderating Effects of Complexity,Uncertainty and Munificence*

Drawing on the resource‐based view of the firm, we examine how complexity, uncertainty and munificence in the general business environment moderate the association between a firm's stakeholder integration capability and its environmental strategy. Our data were drawn from 134 ski resorts in 12 countries in western Europe and North America. Our study finds that (1) an organizational capability of stakeholder integration is associated with a service firm's adoption of a proactive environmental strategy; (2) an uncertain business environment has a direct positive influence and a complex business environment has a direct negative influence on a firm's environmental strategy; and (3) complexity has a negative moderating influence on the relationship between a firm's stakeholder integration capability and its environmental strategy.     

A Pilot Study Evaluating Students' Interest in International Social Work Education

International social work (ISW) has gained traction across the USA with a number of schools taking the lead in promoting the values of social work through exchange programs, service learning, and volunteerism. The internalization of campus through the proactive action of institutions to incorporate global perspectives into teaching, learning, and research in order to build intercultural competence among students, faculty, and staff has received little attention. This paper assesses the level of interest of social work students at a large urban university in the southwestern USA in embracing ISW and how they conceptualized their learning needs. Using a self-administered web-based survey offered to a total of 1,500 social work students with 18% respondent rate, the research determined through a chi-square test that students in Bachelor of Social Work, Master of Social Work, and PhD programs had a significant difference in preferences in areas of interests (χ² = 153, p ≤ 0.000). Overall, students demonstrated interest in direct practice (74.3%) and community and administrative practice (16.6%). Students also differed in their level of interest in participating in international exchange programs (χ² = 9.6, p = 0.047). Discussions address specific and unique interests categorized broadly as ‘globalized social worker,’ ‘humanitarian social worker,’ and ‘policy social worker,’ each of which requires specific skillsets and advanced behavior skills.     

Dialect stabilization and speaker awareness in non‐native varieties of English1

Research on indigenized non‐native varieties of English has aimed to distinguish these varieties from individual second language learning in structural and social terms ( B. Kachru 1983 ; Platt, Weber and Ho 1984 ; Cheshire 1991 ) ; however, quantitative evidence of this divergence remains scarce. Through an analysis of a range of Indian English speakers in a contact situation in the United States, this study distinguishes developing dialect features from second language learning features and explores the concomitant emergence of dialect consciousness. First, an implicational analysis shows that some non‐standard variables (past marking, copula use, agreement) exhibit a second language learning cline while others (articles) form a more stable, incipient non‐standard system shared to some extent by all speakers; a multivariate analysis suggests that both sets of variables are governed by proficiency levels. Next, the explanatory scope of proficiency is assessed by examining the use of selected phonological variants (rhoticity, l‐velarization, aspiration). The use of these features resembles native‐like style‐shifting, as it appears to be more sensitive to speakers’ attitudinal stances than to proficiency levels. This points to the importance of understanding emerging speaker awareness and perceptions of stigma, risk, and value in new varieties of English.
