Going Private in Public: A study on shift in behavioral trend using Facebook

The growth of social media has open a new dimension of research in the domain of human Psychology. The data generated by virtue of various available social media platforms is enormous, dynamic, unstructured, imprecise and most of the time uncertain. Facebook has emerged as one of the most successful media of social interaction and thus, contributing a lot to understand various aspects of human behavior. In this paper, a specific and crucial aspect of human nature is being explored- “Going Private in Public”. This aspect deals with some unexploited trend of human psychology and the research work presented in this paper is planned such as to investigate the data that eventually helps to understand this aspect to a great extent. A questionnaire to capture some behavioral trends of Facebook user was designed and filled up using both online and offline mode. The questionnaire included sets of non-identifying demographic questions, Facebook Intensity scale, Social and Emotional Loneliness Scale for Adult, Perceived Stress Scale and NEO-PI-R model. Filling of the forms was made voluntarily and anonymously to avoid any biasing. A total of 312 responses were received and analyzed using Independent-Sample t-test, Cronbach's alpha test, Exploratory factor analysis, and MANOVA etc.     

Optimization of variable demand fuzzy economic order quantity inventory models without and with backordering

A variable demand inventory model was developed for minimizing inventory cost, treating the holding and ordering costs and demand as independent fuzzy variables. Thereafter, backordering cost was also considered as an independent fuzzy variable. Fuzzy expected value model and fuzzy dependent chance programming model were constructed to find the optimal economic order quantity, which would minimize the fuzzy expected value of the total cost, so that the credibility of the total cost not exceeding a certain budget level was maximized. Optimization was carried out using genetic algorithms and particle swarm optimization algorithm, and their performances were compared. The developed model was found to be efficient not only in one artificial case study but also in two data sets collected from the industries. Therefore, this model could solve real-world problems, too.     

Sex differences in interpersonal problems: A circumplex analysis.

The structure and magnitude of sex differences in interpersonal problems across several data sets were examined, guided by the interpersonal circumplex model and the structural summary method. Data were self-reported interpersonal difficulties, assessed with the 64-item version of the Inventory of Interpersonal Problems (IIP; L. M. Horowitz, S. E. Rosenberg, B. A. Baer, G. Ure?o, & V. S. Villase?or, 1988). In Study 1, the authors focused on sex differences at the level of specific interpersonal complaints (item level). In Study 2, the authors examined sex differences in octant scores of the IIP circumplex (scale level), in a reanalysis of archival data. The structural summary method was used to identify points of maximum difference between men and women in the interpersonal continuum and to estimate effect sizes. Results from the 2 studies converged in suggesting a dimension of difference involving problems in Hostile-Dominance vs. Friendly-Submission. The magnitude of effect size was consistent with previous reports in the personality literature. These sex differences appeared to be best explained by a one-dimensional model. Findings were generally consistent across 3 different types of samples. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pretreatment predictors of dropout from cognitive behavioral therapy for PTSD in Iraq and Afghanistan war veterans.

Cognitive–behavioral therapies (CBTs) can be effective treatments for posttraumatic stress disorder (PTSD) but their effectiveness is limited by high rates of premature dropout. Few studies have compared pretreatment characteristics of treatment completers and dropouts, and only one has examined these factors in Operations Iraqi Freedom and Enduring Freedom (OIF/OEF) Veterans. This study analyzed archival clinical data from 117 OEF/OIF Veterans evaluated and treated through a Veterans Affairs PTSD clinic. High numbers dropped out of treatment (68%). Treatment dropouts (n = 79) and completers (n = 38) differed significantly on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales, PTSD symptom severity, and age. Regression analyses identified one MMPI-2 scale, TRT (negative treatment indicators), and age as unique but modest predictors of dropout.

The Hinterland Urbanised?

What defines the urban? And can the non-urban necessarily always be classified as rural? Neil Brenner , Director of the Urban Theory Lab at Harvard University Graduate School of Design, reflects on the lack of an overarching theory to describe these realms, and argues that what we call the countryside or the hinterland has become key to the process of capitalist urbanisation.

Emission inventory of VOCs from mobile sources in a metropolitan region

Based on methodologies developed by US EPA, European EMEP/CORINAIR, and Australian NPI, and the former emission inventory in Korea, two methods were applied to 151 villages in northeastern Seoul, Korea to estimate emission of VOCs from line and area vehicle sources depending on vehicle types with different fuel types. A discharge coefficient method for the line source on the Eastern main road was calculated by multiplying the emission amounts per unit of mileage, and a fuel exhaust coefficient method for the area vehicle sources on other roads was determined as multiplying the emission rates by the actual consumption of excess fuel. Results indicated the methods could be adequate for estimating the amounts of mobile emissions when limited information on mobile emission is available. The methods can be used to develop the emission model for all VOCs emission sources (point and non-point sources), which provides input data of atmospheric models.

Assessment of obsessive-compulsive symptom dimensions: Development and evaluation of the Dimensional Obsessive-Compulsive Scale.

Although several measures of obsessive-compulsive (OC) symptoms exist, most are limited in that they are not consistent with the most recent empirical findings on the nature and dimensional structure of obsessions and compulsions. In the present research, the authors developed and evaluated a measure called the Dimensional Obsessive-Compulsive Scale (DOCS) to address limitations of existing OC symptom measures. The DOCS is a 20-item measure that assesses the four dimensions of OC symptoms most reliably replicated in previous structural research. Factorial validity of the DOCS was supported by exploratory and confirmatory factor analyses of 3 samples, including individuals with OC disorder, those with other anxiety disorders, and nonclinical individuals. Scores on the DOCS displayed good performance on indices of reliability and validity, as well as sensitivity to treatment and diagnostic sensitivity, and hold promise as a measure of OC symptoms in clinical and research settings.

From paper to pixels: A comparison of paper and computer formats in psychological assessment

Internet based data collection methods have many advantages for psychological assessment when compared with more traditional paper formats, including, reduced costs, and greater convenience for both the researcher and the participant. However, prior to the wide-spread adoption of these methods, equivalence with paper tests formats must be established. The present study compared questionnaire data from the computer with that from a traditional paper format in a sample of college students both directly and through an opinion survey. Three types of questionnaires that represent distinct areas commonly assessed in psychological research included: quality of life (SF-36), depression (BDI-II) and personality (NEO). A within-subjects design counterbalanced order across the computer and paper formats. Overall the findings showed no differences for the Neuroticism and Extraversion facts of the NEO, for the BDI and for the subscales and composite scores of the SF-36. Significant differences were found between the paper and computer formats for the Openness, Agreeableness, and Conscientiousness facets of the NEO. Additionally, the computer was perceived to be convenient, user-friendly, comfortable, and secure. Results suggest that a computerized format is an efficient way to conduct quality of life research, especially for the assessment of distress levels and quality of life.
