A Method of Finding Predictor Genes for a Particular Disease Using a Clustering Algorithm

Clustering Algorithms are nowadays really important tools in microarray data analysis. The different clustering algorithm generally used in biological science does not take into consideration the underlying probability distribution of the data. In this sense, they are heuristic in nature. In this work we proposed a clustering algorithm based on EM Algorithm. It gives 28% less misclassification than the K-means algorithm (which is mostly use in Bio science). We have also shown on a real data set that this algorithm can be efficiently used for detecting the genes which are responsible for a particular disease.

Improving Expatriation Success: The Roles of Regulatory Focus and Burnout

The study empirically and theoretically contributes to the human resource management discipline by developing and testing a cohesive model drawing on the pertinent literature from expatriate management, burnout and regulatory focus theory. Drawing on data from 233 expatriate managers, the study aims to examine the relationships between expatriate adjustment and the outcomes of job satisfaction and withdrawal cognitions via expatriate burnout. Specifically, the findings reveal that (a) higher levels of both work adjustment and interaction adjustment lead to reduced expatriate burnout, with the former having a greater effect on burnout than the latter; (b) burnout serves as a full mediator between work adjustment and withdrawal cognitions, and a partial mediator between work adjustment and job satisfaction; and (c) regulatory focus serves to moderate expatriate adjustment–outcome consequences, i.e. promotion‐focused (as opposed to prevention‐focused) expatriates demonstrate a stronger burnout–job satisfaction relationship. Several implications are extracted from the study for regulatory theory, burnout and expatriation management practices as well as suggested avenues for future research.     

High school students’ academic causal attributions in the cultural-political context of the Arab school system in Israel

While motivation is commonly interpreted as an individual student’s characteristic, motivational perceptions and beliefs, such as causal attributions of success and failure, are embedded in cultural meanings and contextual practices. The current study aimed to investigate causal attributions among Arab high school students in Israel and to interpret them in the light of their cultural-political context. Two hundred and five 11th-grade Arab students from three different geographic regions in Israel responded to open-ended and closed survey questions about events of success and failure in school. The analysis indicated that students overwhelmingly considered exams when thinking about events of success and failure, reflecting the normative teacher-centred pedagogical practices in schools. The analysis also manifested patterns of a self-serving bias. These findings are interpreted in the light of the cultural-political characteristics of the Arab school system in Israel.     

Protection of privacy in efficient application of randomized response techniques

In estimating the proportion of people bearing a sensitive attribute A, say, in a given community, following Warner’s (J Am Stat Assoc 60:63–69, 1965) pioneering work, certain randomized response (RR) techniques are available for application. These are intended to ensure efficient and unbiased estimation protecting a respondent’s privacy when it touches a person’s socially stigmatizing feature like rash driving, tax evasion, induced abortion, testing HIV positive, etc. Lanke (Int Stat Rev 44:197–203, 1976), Leysieffer and Warner (J Am Stat Assoc 71:649–656, 1976), Anderson (Int Stat Rev 44:213–217, 1976, Scand J Stat 4:11–19, 1977) and Nayak (Commun Stat Theor Method 23:3303–3321, 1994) among others have discussed how maintenance of efficiency is in conflict with protection of privacy. In their RR-related activities the sample selection is traditionally by simple random sampling (SRS) with replacement (WR). In this paper, an extension of an essential similarity in case of general unequal probability sample selection even without replacement is reported. Large scale surveys overwhelmingly employ complex designs other than SRSWR. So extension of RR techniques to complex designs is essential and hence this paper principally refers to them. New jeopardy measures to protect revelation of secrecy presented here are needed as modifications of those in the literature covering SRSWR alone. Observing that multiple responses are feasible in addressing such a dichotomous situation especially with Kuk’s (Biometrika 77:436–438, 1990) and Christofides’ (Metrika 57:195–200, 2003) RR devices, an average of the response-specific jeopardizing measures is proposed. This measure which is device dependent, could be regarded as a technical characteristic of the device and it should be made known to the participants before they agree to use the randomization device. The views expressed are the authors’, not of the organizations they work for. Prof Chaudhuri’s research is partially supported by CSIR Grant No. 21(0539)/02/EMR-II.     

Dream Recall Frequency and Unusual Dream Experiences in Early Adolescence: Longitudinal Links to Behavior Problems

Unique dream patterns are related to psychopathological distress in adults. In adolescence, this was investigated almost exclusively regarding nightmares. This longitudinal study examines developmental trajectories of various adolescent‐reported dream patterns, and their associations with parent‐reported psychopathology (internalization and externalization problems) in early adolescence. Ninety‐four 10‐ to 11‐year‐old normally developing children completed a week of sleep, dreaming, and pubertal development assessments. Parents reported behavior problems. Assessments were repeated after 1 and 2 years. Reports of unusual dreams decreased over time, and dream recall decreased among girls. Internalizing symptoms longitudinally predicted an increase in dream recall and unusual dreams. Moreover, unusual dreams longitudinally predicted increased behavior problems (internalization and externalization). Assessing dream patterns during early adolescence may help early detection of covert psychopathological distress.     

DOMAIN ESTIMATION IN FINITE POPULATIONS1

This paper suggests unbiased estimators (UE's) for the size, mean and total of a domain, with specific features, in a given finite population on the basis of simple random sampling without replacement (SRSWOR) continued till a preassigned number of domain members is observed.     

The 3 F 2 with Complex Parameters as Generating Function of Discrete Distribution

A new discrete family of probability distributions that are generated by the ₃ F ₂ function with complex parameters is presented. Some of the properties of this new family are studied as well as methods of estimation for its parameters. It affords considerable flexibility of shape which turns the distribution into an appropriate candidate for modeling data that cannot be adequately fitted by classical families with fewer parameters. Finally, three examples in the fields of Agriculture and Education are included in order to show the versatility and utility of this distribution.     

Bhattacharyya distance based linear discriminant function for stationary time series

The problem of classifying a covariance stationary normal time series is considered. Under certain regularity conditions, a compact form of the linear discriminant function in the sense of maximizing the Bhattacharyya distance is obtained.     

Green Criminology and Environmental Crimes and Harms

The focus of criminology on crimes and harms committed by and against humans has broadened over time. Only since the 1990s, however, has the discipline recognized the significance of crimes and harms concerning the environment and nonhuman animals. A variety of approaches and bodies of work now contribute to what can be described as “green criminology.” This article summarizes research on types of environmental crime and harm, as well as different eco‐philosophical orientations and related justice‐based approaches. It concludes with an example illustrating the ways in which these approaches may overlap.
