Role of flexibility in supply chain design and modeling—Introduction to the special issue

In this introductory note, we describe the motivation behind this special issue on supply chain design and modeling. We begin by noting the potential opportunities offered by flexibility of a system in enhancing its functionalities and capabilities. After defining the nature of flexibility, we briefly describe flexibility in a supply chain, pertinent issues, and potential tools and techniques utilized for designing and modeling flexibility in it. We close out with a brief review of the articles in this issue and their relevance to the interests of decision makers.     

Estimation of Disaggregate-Level Poverty Incidence in Odisha Under Area-Level Hierarchical Bayes Small Area Model

Sustainable development goal-1 of the United Nations is to end poverty in all its forms everywhere. The estimates of poverty related parameters obtained from large scale sample survey are often available at large domain level (e.g. state level). But, poverty rates are not uniformly distributed across the regions. The regional variations are masked in such large domain level estimates. However, for monitoring the progress of poverty alleviation programmes aimed at reduction of poverty often require micro or disaggregate level estimates. The traditional survey estimation approaches are not suitable for generating the reliable estimates at this level because of sample size problem. It is the main endeavor of Small Area Estimation (SAE) approach to produce micro level statistics with acceptable precision without incurring any extra cost and utilizing existing survey data. In this study, the Hierarchical Bayes approach of SAE has been applied to generate reliable and representative district level poverty incidence for the State of Odisha in India using the Household Consumer Expenditure Survey 2011–2012 data of National Sample Survey Office and linked with Population Census 2011. The results show the precise performance of model based estimates generated by SAE method to a greater extent than the direct survey estimates. A poverty map has also been produced to observe the spatial inequality in poverty distribution.

A study of subjective visual disturbances in jewellery manufacturing

Subjective Visual Disturbances are silent adversaries that appear over a period of continued exposure and arise when the visual demands of the tasks exceed the visual abilities of the user. Jewellery manufacturing activity involves precision designs, setting the metal and stones, polishing and filing which requires higher visual demand. Therefore, it is expected that the jewellery manufacturing workers may experience subjective visual disturbances. This study was taken up with the following objectives 1) To study the presence of subjective visual disturbances among jewellery manufacturing workers and compare the same with VDT operators 2) To study the effect of work exposures on subjective visual disturbances and 3) to ascertain whether subjective visual disturbances have any permanent vision related problems. The study was carried out on jewellery manufacturing workers, VDT operators and on graduate students. The symptoms of subjective visual disturbances were identified using a questionnaire developed by Sheedy (2003). Viewing distances were measured and visual angles were calculated. The eye check--ups were also carried out. The subjective visual disturbances were higher in jewellery manufacturing workers. The findings suggest that work exposure has an impact on the causation of subjective visual disturbances. No pathological conditions of the eyes were observed.     

A new approach: Interrelated two-way clustering of gene expression data

The paper presents a new approach to interrelated two-way clustering of gene expression data. Clustering of genes has been effected using entropy and a correlation measure, whereas the samples have been clustered using the fuzzy C-means. The efficiency of this approach has been tested on two well known data sets: the colon cancer data set and the leukemia data set. Using this approach, we were able to identify the important co-regulated genes and group the samples efficiently at the same time.     

The Role of Caring in the Teacher-Student Relationship for At-Risk Students

This study uses information from both teachers and students to explore how the perceptions of each other's investment in the relationship affects the productivity of the relationship. Using the National Longitudinal Study of 1988 (NELS), I analyze the conditions and academic consequences of students'investment in the relationship with teachers and school. I find that teachers'perceptions that the student puts forth academic effort and students'perceptions that teachers are caring are each weakly associated with mathematics achievement for most students. For students who are judged by their teachers as at risk of dropping out of high school, however, the value for math achievement of having teachers who care is substantial and mitigates against the negative effect of having been judged as at risk. The results suggest that social capital, as defined by a relationship that facilitates action, is especially high for at-risk students who feel their teachers are interested, expect them to succeed, listen to them, praise their effort, and care.     

A Longitudinal Analysis of Contextual Exposure to Peers with College Educated Parents and Students' College Enrollment

Students with college educated parents are more likely to attain higher levels of education than students of parents with lower levels of education. Past research has explained this favorable outcome as the result of advantageous placement and greater availability of educational resources. Using data from Add Health and AHAA, we find evidence that exposure to students of college educated parents at the school level and within courses increase the likelihood of four year college enrollment even after controlling for family background, achievement, and placement. We also found that exposure to students of college educated parents has especially strong positive effects on college enrollment for students whose own parents do not have a college degree. These findings suggest that greater exposure to students of highly educated parents at the school level and within courses partially explains the favorable educational attainment of students with college educated parents.     

Jurisdiction,inscription, and state formation: administrative modernism and knowledge regimes

In seventeenth-century France, Colbert built a more effective state administration not by rationalizing state offices but by using public documents to increase the government’s intellectual capacity to exercise logistical power and engage in territorial governance. This pattern calls into question Weber’s model of the genesis of “modern officialdom,” suggesting that its source was not social rationalization, but rather the identification and management of expertise. Colbert recruited into government nascent technocrats with knowledge useful to territorial politics, using contracts and other documents to limit their independence and subordinate them to patrimonial authorities. They exercised specific duties and impersonal powers in jurisdictional areas—much like modern technocrats. Their expertise enhanced the intellectual capacity of the administration to exercise territorial power and made the state less dependent on patrimonial clienteles without challenging the patrimonial culture of power/knowledge.
