TL;DR: The authors compared the influence of four bases for self-evaluation (controlling one's life, doing one's duty, benefitting others, achieving social status) among 4,852 adolescents across 20 cultural samples.
Abstract: Several theories propose that self-esteem, or positive self-regard, results from fulfilling the value priorities of one’s surrounding culture. Yet, surprisingly little evidence exists for this assertion, and theories differ about whether individuals must personally endorse the value priorities involved. We compared the influence of four bases for self-evaluation (controlling one’s life, doing one’s duty, benefitting others, achieving social status) among 4,852 adolescents across 20 cultural samples, using an implicit, within-person measurement technique to avoid cultural response biases. Cross-sectional and longitudinal analyses showed that participants generally derived feelings of self-esteem from all four bases, but especially from those that were most consistent with the value priorities of others in their cultural context. Multilevel analyses confirmed that the bases of positive self-regard are sustained collectively: They are predictably moderated by culturally normative values but show little systematic variation with personally endorsed values.

TL;DR: In this article, the authors analyzed customer service effects in creating satisfaction and loyalty and found that customer services about atmosphere (CSA) was one of the most important factors in creating customer satisfaction.
Abstract: Purpose – The purpose of this paper is to analyse customer service effects in creating satisfaction and loyalty. The other antecedents of satisfaction and loyalty such as perceived value and service quality were not analysed in this research. Design/methodology/approach – Exploratory factor analysis was used to classify customer service items. Confirmatory factor analysis was not applied because of there was not any significant theory based on the classification of shopping centre customer service (SCCS). The research model was developed to show the relationships and the effects of customer service which were tested through multiple regression analyses. Findings – As a result of findings, customer service variables were classified into eight factors. Only four of them had effects on satisfaction and loyalty. The findings indicated that customer services had effects on customer satisfaction and loyalty. It was shown that “customer services about atmosphere (CSA)” affected both satisfaction and loyalty wher...

TL;DR: In this article, the authors investigate the effect of managers' interventions on the prevalence of knowledge sharing, joint development, and client ties in science and technology parks (STPs) by collecting data from managers and tenants of 12 STPs in Turkey.
Abstract: Science and technology parks (STPs) try to facilitate networking among their tenants by (i) creating a favorable ecology for collaboration through selection of tenants and (ii) encouraging the formation of ties among these firms through events and introductions. We investigate the effect of these interventions on data collected from managers and tenants of 12 STPs in Turkey. In analyses that include STP level fixed effects to control for unobserved heterogeneity in parks' characteristics, we find ecological characteristics as well as manager interventions to have some effect on prevalence of inter-firm relationships: Sectoral homogeneity is associated with greater numbers prevalence of knowledge sharing, joint development, and client ties. Tenants whose general managers have greater presence at the park have more equipment-sharing ties, and attendance at STP-organized events increases knowledge-sharing ties. STP managers� brokerage activities contribute to equipment sharing ties.
TL;DR: In this paper, the authors investigate the role of globalization and other sources of threat to account for the trend away from religious freedom in 147 nations and find that as threat to the majority religion increases, due to globalization and an increasing number of minority religions, freedom of religion is on the decline.
Abstract: While arguably central to the human experience, religion is a largely understudied component of social life and of politics. The comparative literature on religion and politics is limited in scope, and offers mostly descriptions of trends. We know, for example, that restrictions on freedom of religion are on the rise worldwide. In our theoretical framework, the recently higher universal levels of globalization combine with other sources of threat to account for the trend away from religious freedom. As threat to the majority religion increases, due to globalization and an increasing number of minority religions, freedom of religion is on the decline. Data for two decades from 147 nations are used to test hypotheses. Time-series cross-sectional and mediation models estimated at different levels of analysis with data from two independent sources confirm that threat systematically accounts for changes in religious freedom, with globalization playing a key role.

TL;DR: The conjecture that emotional stimuli might seem more familiar because they share features with studied items from the same category is explored, suggesting that liberal memory bias for emotional items may be largely driven by effects of category membership.
Abstract: Recognition memory studies often find that emotional items are more likely than neutral items to be labelled as studied. Previous work suggests this bias is driven by increased memory strength/familiarity for emotional items. We explored strength and bias interpretations of this effect with the conjecture that emotional stimuli might seem more familiar because they share features with studied items from the same category. Categorical effects were manipulated in a recognition task by presenting lists with a small, medium or large proportion of emotional words. The liberal memory bias for emotional words was only observed when a medium or large proportion of categorised words were presented in the lists. Similar, though weaker, effects were observed with categorised words that were not emotional (animal names). These results suggest that liberal memory bias for emotional items may be largely driven by effects of category membership.
TL;DR: It is suggested that regeneration mode must be a major component of any vegetation or forest stand dynamics model in the Mediterranean Basin, and can potentially be extrapolated to other Mediterranean-type fire-prone ecosystems.
Abstract: Regeneration mode is one of the key attributes determining population structure and dynamics of plant species. We investigated long-term patterns after fire in the cover of plant species in a 100-year chronosequence of burned Pinus brutia forests in a humid Mediterranean climate region in Turkey. Significant trends were present in the change of cover in major species through post-fire chronosequence, and species with similar trends were clustered in relation to their regeneration modes. Obligate resprouters increased their cover from the early post-fire years to the later stages, while cover of obligate seeders with a soil seed bank increased in the early years, but then decreased through time. Facultative resprouters were at an intermediate position, with an increase in cover until mid-successional stages and then a decrease through time. The cover of the only obligate seeder with a canopy seed bank (P. brutia) followed a linear increasing trend during the succession. When species with the same regeneration mode were grouped, the same trends were observed with more explained variances. A few life-history traits were enough to explain the observed trends. Our study shows that regeneration mode is an explanatory functional grouping system for describing long-term post-fire dynamics of Mediterranean Basin woody species. We suggest that regeneration mode must be a major component of any vegetation or forest stand dynamics model in the Mediterranean Basin. This result has important implications for the management of Mediterranean Basin ecosystems, and can potentially be extrapolated to other Mediterranean-type fire-prone ecosystems.

TL;DR: In this article, the authors focus on increasing the efficiency of the yard via consideration of the container stacking optimization problem for transshipment, inbound and outbound containers at a container terminal.
Abstract: There are three crucial resources at container terminals; the yard, cranes and the vehicles. The main objective of the terminal is the efficient use of these resources while performing different operations. The yard is a temporary storage area where containers remain until transported to their next location by truck, train or vessel. Containers are stacked on top of each other in order to utilize the yard space efficiently. However, stacking cranes can only directly access those containers at the top of the stack. As a result, reshuffling/shifting occurs, defined as an unproductive move of a container required to access another container stored underneath. We focus on increasing the efficiency of the yard via consideration of the container stacking optimization problem for transshipment, inbound and outbound containers at a container terminal. The objective of the problem is to minimize container storage and retrieval times through avoidance of reshuffles, resulting in more efficient loading/unloading operations, and in turn minimizing the dwell time of containers. The main inputs are the type, weight, discharge port/location, destined vessel/vehicle of the container, and the expected departure time. Different stacking policies are proposed in this study, and we also investigate the problem of allocating the transit container to outbound vessels to minimize dwell time at the terminal. Transit containers require multiple sea-trips to reach their final destination. Vessels departing from the terminal and destined for the same port may provide exchangeable trips for this type of container, based on their several attributes and capacity restrictions. We consider this problem taking into account several factors that affect container/trip allocation decisions. The solution of this problem also has implications for the stacking problem.
