Evaluation of Early Adolescent Subjective Well-Being in Terms of Submissive Behavior and Self-Esteem

This research aimed to investigate the correlation between subjective well-being and submissive behavior and self-esteem in students in the early adolescent period. The research was completed with a relational design. The research group comprised sixth, seventh, and eighth class middle school students in the spring term of the 2015–2016 academic year in Trabzon province. Data collection tools included a Personal Information Form, Submissive Behavior Scale, Two-Dimensional Self-Respect Scale (Self-Liking and Self-Confidence Scale), Satisfaction with Life Scale and Positive and Negative Affect Schedule. The results of the correlation analysis found a significant positive correlation between subjective well-being and self-esteem (r?=?0.54, p?<?0.01; 95% CI [0.44, 0.61], Cohen’s d?=?1.28); however, the correlation between subjective well-being and submissive behavior was not significant (r?=?–0.02, p?>?0.05; 95% CI [–0.11, 0.09], Cohen’s d?=?0.04). There was a significant negative correlation identified between self-esteem and submissive behavior (r?=?–0.10, p < 0.05; 95% CI [–0.20, –0.01], Cohen’s d?=?–0.20). Additionally, according to our findings, self-esteem accounts for 29% of the variation in well-being (F(1, 367)?=?150.79, p?<?0.001). The contribution of self-esteem to the subjective well-being explanatory model was found to be significant (sz?=?0.54, p?<?0.001).     

Petroleum and Hazardous Material Releases from Industrial Facilities Associated with Hurricane Katrina

Hurricane Katrina struck an area dense with industry, causing numerous releases of petroleum and hazardous materials. This study integrates information from a number of sources to describe the frequency, causes, and effects of these releases in order to inform analysis of risk from future hurricanes. Over 200 onshore releases of hazardous chemicals, petroleum, or natural gas were reported. Storm surge was responsible for the majority of petroleum releases and failure of storage tanks was the most common mechanism of release. Of the smaller number of hazardous chemical releases reported, many were associated with flaring from plant startup, shutdown, or process upset. In areas impacted by storm surge, 10% of the facilities within the Risk Management Plan (RMP) and Toxic Release Inventory (TRI) databases and 28% of SIC 1311 facilities experienced accidental releases. In areas subject only to hurricane strength winds, a lower fraction (1% of RMP and TRI and 10% of SIC 1311 facilities) experienced a release while 1% of all facility types reported a release in areas that experienced tropical storm strength winds. Of industrial facilities surveyed, more experienced indirect disruptions such as displacement of workers, loss of electricity and communication systems, and difficulty acquiring supplies and contractors for operations or reconstruction (55%), than experienced releases. To reduce the risk of hazardous material releases and speed the return to normal operations under these difficult conditions, greater attention should be devoted to risk‐based facility design and improved prevention and response planning.     

Leadership competencies for implementing planned organizational change

This paper bridges the leadership and organizational change literatures by exploring the relationship between managers' leadership competencies (namely, their effectiveness at person-oriented and task-oriented behaviors) and the likelihood that they will emphasize the different activities involved in planned organizational change implementation (namely, communicating the need for change, mobilizing others to support the change, and evaluating the change implementation). We examine this relationship using data from 89 clinical managers at the United Kingdom National Health Service who implemented change projects between 2003 and 2004. Our results lend overall support to the proposed theory. This finding suggests that treating planned organizational change as a generic phenomenon might mask important idiosyncrasies associated both with the different activities involved in the change implementation process and with the unique functions that leadership competencies might play in the execution of these activities.     

The Determinants of Life Satisfaction Among Adolescents: The Role of Metacognitive Awareness and Self-Efficacy

This study investigated the associations among the life satisfaction, metacognitive awareness and perceived self-efficacy. It also investigated whether life satisfaction, metacognitive awareness and perceived self-efficacy vary according to gender. The study was performed with 492 students attending high schools. The Life Satisfaction Scale, Cognitive Awareness Scale, Self-Efficacy Scale and an Individual Data Form were used for data collection. Pearson correlation coefficient results revealed that life satisfaction was significantly positively correlated with metacognitive awareness (r = .36, p < .001) and self-efficacy (r = .28, p < .001). Multiple regression analysis revealed that metacognitive awareness and self-efficacy accounted for 15 % of life satisfaction (F_(2,489) = 45.25, p < .001). Metacognitive awareness (ß = .29, p < .001) and self-efficacy (ß = .16, p < .001) make a significant original contribution to the model. In addition, the results show that adolescents do not vary according to life satisfaction (F = .10, p = .74, η²= .00), metacognitive awareness (F = .01, p = .91, η² = .00) or self-efficacy (F = 2.21, p = .13, η² = .00). The study results show that metacognitive awareness and self-efficacy are significant predictors of life satisfaction in adolescents.     

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.     

A fiducial-based approach to the one-way ANOVA in the presence of nonnormality and heterogeneous error variances

In this study, we propose a new test for testing the equality of the treatment means in one-way ANOVA when the usual normality and the homogeneity of variances assumptions are not met. In developing the proposed test, we benefit from the Fisher's fiducial inference [1–3]. Distribution of the error terms is assumed to be long-tailed symmetric (LTS) which includes the normal distribution as a limiting case. Modified maximum likelihood (MML) estimators are used in the test statistics rather than the traditional least squares (LS) estimators, since LS estimators have very low efficiencies under nonnormal distributions, see Tiku [4] for the details of MML methodology. An extensive Monte Carlo simulation study is done to compare the efficiency of the proposed test with the corresponding test based on normal theory, see Li et al. [5]. Finally, we give a real life example to show the applicability of the proposed methodology.
