The relationship between problematic internet use and interpersonal cognitive distortions and life satisfaction in university students

Objective

The aim of the study was to analyze the relationship between problematic internet use by college students and interpersonal cognitive distortions and life satisfaction.

Methods

A total of 418 students, 260 females and 158 males, studying in different departments of the Fatih Faculty of Education, Karadeniz Technical University, participated. The Online Cognition Scale, Interpersonal Cognitive Distortions Scale, Life Satisfaction Scale and Personal Information Form were used as instruments.

Results

A significant positive correlation was determined between problematic internet use and interpersonal cognitive distortions (r = .33, p < .01), and a negative one with life satisfaction (r = − .21, p < .01). Interpersonal cognitive distortions, life satisfaction and gender account for 21% of total variance (F₍₃₄₁₃₎ = 37.30, p < .05). Findings revealed that males exhibit more problematic internet use than females, which subjects with a pessimistic perception of events have a higher level of problematic internet use than those with an optimistic perception and that subjects who always feel lonely exhibit greater problematic internet use than those who never or only sometimes experience feelings of loneliness.

Conclusions

Interpersonal cognitive distortions, life satisfaction and gender were significant predictors of problematic internet use. Problematic internet use exhibits significant variations according to gender, perception of events and feelings of loneliness.     

Fluid adaptation of contested citizenship: second-generation migrant Turks in Germany and the United States

This paper explores belonging in the context of legal citizenship for second-generation Turkish immigrants in Berlin and in New York. Fluid adaptation refers to the discursive boundaries of immigrant identity articulations, the contextual and shifting adjustments immigrants make to their sense of belonging. Immigrant belonging, gauged by ‘encounters’ with bureaucracies and participatory expressions, is shaped in large part by the receiving state's legal framework and citizenship status. Belonging is complicated by racialization and exclusion, and affected by intersectionalities of immigrant experience. Limited citizenship models necessitate deployment of fluid and alternative membership models. Alternative forms of belonging underscore the power of the nation-state in delimiting belonging.     

An integrated multi-objective decision-making process for multi-period lot-sizing with supplier selection

Supplier selection is a multi-criteria problem which includes both tangible and intangible factors. In these problems if suppliers have capacity or other different constraints two problems will exist: which suppliers are the best and how much should be purchased from each selected supplier? In this paper an integrated approach of analytic network process (ANP) and multi-objective mixed integer linear programming (MOMILP) is proposed. This integrated approach considers both tangible and intangible factors in choosing the best suppliers and defines the optimum quantities among selected suppliers to maximize the total value of purchasing (TVP), and to minimize the total cost and total defect rate and to balance the total cost among periods. The priorities are calculated for each supplier by using ANP. Four different plastic molding firms working with a refrigerator plant are evaluated according to 14 criteria that are involved in the four clusters: benefits, opportunities, costs and risks (BOCR). The priorities of suppliers will also be used as the parameters of the first objective function. This multi-objective and multi-period real-life problem is solved by using previous techniques and a reservation level driven Tchebycheff procedure (RLTP). Finally the most preferred nondominated solutions are determined by considering the decision maker's (DM's) preferences and the results obtained by these techniques are compared.     

Modelling oil and gas supply disruption risks using extreme-value theory and copula

In this paper, we are concerned with modelling oil and gas supply disruption risks using extreme-value theory and copula. We analyse financial and volumetric losses due to both oil and gas supply disruptions and investigate their dependence structure using real data. In order to illustrate the impact of crude oil and natural gas supply disruptions on an energy-dependent economy, Nigeria is considered as a case study. Computational studies illustrate that the generalized extreme-value distribution anticipates higher financial losses and extreme-value copulas produce the best fit for financial and volumetric losses compared with normal copulas. Moreover, multivariate financial losses exhibit stronger positive dependence than volumetric losses.     

Work–family Conflict and Job Satisfaction Relationship: The Roles of Gender and Interpretive Habits

This study examined the effects of gender and interpretive habits on the relationship between work–family conflict (WFC) and job satisfaction. The results of the analysis of the data collected from 286 academic personnel suggest that interpretive habits moderate the relationship between WFC and job satisfaction such that the negative effect of WFC and job satisfaction is stronger for employees focusing highly on deficiency, with high necessitating, and low skill recognition, referred to as stress‐predisposing interpretive habits. Furthermore, gender was found to have an influence on the role of interpretive habits in the WFC–job satisfaction relationship. Specifically, WFC had a negative association with job satisfaction for stress‐predisposed male employees while no relationship was found between WFC and job satisfaction for men with a low focus on deficiency, low necessitating and high skill recognition namely, stress‐resilient interpretive habits. Moreover, although WFC had a negative association with job satisfaction for female employees, this relationship was even stronger for stress‐resilient females. The implications of the findings and suggestions for future studies are discussed.     

Low skeletal muscle mass index is associated with function and nutritional status in residents in a Turkish nursing home

Introduction: To determine the prevalence of low muscle mass (LMM) and the relationship between LMM with functional and nutritional status as defined using the LMM evaluation method of European Working Group on Sarcopenia in Older People (EWGSOP) criteria among male residents in a nursing home.

Methods: Male residents aged?>60 years of a nursing home located in Turkey were included in our study. Their body mass index (BMI) kg/m², skeletal muscle mass (SMM-kg) and skeletal muscle mass index (SMMI-kg/m²) were calculated. The participants were regarded as having low SMMI if they had SMMI?<9.2?kg/m² according to our population specific cut-off point. Functional status was evaluated with Katz activities of daily living (ADL) and Lawton Instrumental Activities of Daily Living (IADL). Nutritional assessment was performed using the Mini Nutritional Assessment (MNA). The number of drugs taken and chronic diseases were recorded.

Results: One hundred fifty-seven male residents were enrolled into the study. Their mean age was 73.1?±?6.7 years with mean ADL score of 8.9?±?2.0 and IADL score of 8.7?±?4.6. One hundred twelve (71%) residents were aged?>70 years. Thirty-five men (23%) had low SMMI in group aged?>60 years, and twenty-eight subjects (25%) in the group aged?>70 years. MNA scores were significantly lower in residents with low SMMI compared with having normal SMMI (17.1?±?3.4 versus 19.6?±?2.5, p?=?0.005). BMI was significantly lower in the residents with low SMMI compared with normal SMMI (19.6?±?2.7 versus 27.1?±?4.1, p70 years (8.1?±?2.6 versus 9.1?±?1.6, p?=?0.014). In regression analyses, the only factor associated with better functional status was the lower age (p?=?0.04) while the only factor associated with better nutrition was higher SMMI (p?=?0.01).

Conclusions: Low SMMI detected by LMM evaluation method of EWGSOP criteria is prevalent among male nursing home residents. There is association of low SMMI with nutritional status and probably with functional status within the nursing home setting using the EWGSOP criteria with Turkish normative reference cut-off value.
