TL;DR: In this paper, a detailed analysis of GHG emissions in four European countries, due to different types of road transport vehicles is presented. And the implications are presented in order to reduce the greenhouse gas emissions and to meet sustainable development conditions according to the numerical results of the estimation and it is aimed to prepare a base for new studies about GHG emission in road transportation.

TL;DR: In this article, the authors examined the direct and indirect effects of problematic Instagram use on different psychopathological outcomes including loneliness, depression, anxiety, and social anxiety via body image dissatisfaction (BID).
Abstract: In a minority of cases, problematic use of technology can negatively impact on adolescents and impair some aspects of their social, emotional, and psychological development. The purpose of the present study was to examine the direct and indirect effects of problematic Instagram use (PIU) on different psychopathological outcomes including loneliness, depression, anxiety, and social anxiety via body image dissatisfaction (BID). Additionally, moderating role of gender on the relationships among variables was investigated. A total of 491 adolescents (Mage = 15.92 years, SDage = 1.07; range = 14 to 19 years) were recruited for the study to complete a questionnaire that included the relevant assessment tools for the aforementioned variables. Mediation and moderation analyses showed that among male adolescents, PIU was directly associated with loneliness, depression, general anxiety, and social anxiety and BID partially mediated these associations. Among females, PIU was directly associated with depression and indirectly with general anxiety and social anxiety via BID. Gender significantly moderated the direct relationships of PIU with loneliness, general anxiety, and social anxiety. PIU was directly associated with loneliness, general anxiety, and social anxiety among males only, whereas among females, PIU was indirectly associated with general and social anxiety via BID but was not related to loneliness. Results of this study indicate that PIU has different negative psychological effects on male and female adolescents and that BID appears to be one explanatory factor for these impairments especially among females.

TL;DR: In this paper, a bi-objective mixed-integer programming model formulation was developed for the problem using a speed-scaling framework to address the conflicting objectives of minimizing total flowtime and total energy consumption.
Abstract: The permutation flowshop scheduling problem (PFSP) has been extensively explored in scheduling literature because it has many real-world industrial implementations. In some studies, multiple objectives related to production efficiency have been considered simultaneously. However, studies that consider energy consumption and environmental impacts are very rare in a multi-objective setting. In this work, we studied two contradictory objectives, namely, total flowtime and total energy consumption (TEC) in a green permutation flowshop environment, in which the machines can be operated at varying speed levels corresponding to different energy consumption values. A bi-objective mixed-integer programming model formulation was developed for the problem using a speed-scaling framework. To address the conflicting objectives of minimizing TEC and total flowtime, the augmented epsilon-constraint approach was employed to obtain Pareto-optimal solutions. We obtained near approximations for the Pareto-optimal frontiers of small-scale problems using a very small epsilon level. Furthermore, the mathematical model was run with a time limit to find sets of non-dominated solutions for large instances. As the problem was NP-hard, two effective multi-objective iterated greedy algorithms and a multi-objective variable block insertion heuristic were also proposed for the problem as well as a novel construction heuristic for initial solution generation. The performance of the developed heuristic algorithms was assessed on well-known benchmark problems in terms of various quality measures. Initially, the performance of the algorithms was evaluated on small-scale instances using Pareto-optimal solutions. Then, it was shown that the developed algorithms are tremendously effective for solving large instances in comparison to time-limited model.

TL;DR: In this article, the authors argue that the correlation of religion with reduced corruption is conditional on the extent to which political institutions are democratic, and that the nature of this relationship is contingent on the presence of democratic institutions.
Abstract: Critically considering scholarship relating religiosity to ethical behaviour, we contend that religion is systematically related to levels of corruption, and that the nature of this relationship is contingent on the presence of democratic institutions. In democracies, where political institutions are designed to inhibit corrupt conduct, the morality provided by religion is related to attenuated corruption. Conversely, in systems lacking democratic institutions, moral behaviour is not tantamount to staying away from corrupt ways. Accordingly, in non-democratic contexts, religion would not be associated with decreased corruption. Time-series cross-sectional analyses of aggregate data for 129 countries for 12 years, as well as individual level analyses of data from the World Values Surveys, strongly corroborate the predictions of our theory. The correlation of religion with reduced corruption is conditional on the extent to which political institutions are democratic.
