AbstractWe investigate the relationship between climatic and demographic events in Korea during the Chulmun period (10,000–3,500 cal. BP) by analyzing paleoenvironmental proxies and 14C dates. We focus on testing whether a cooling climate, and its potential negative impact on millet productivity around the mid 5th-millennium cal. BP, triggered the population decline suggested by the archaeological record. We employ a Bayesian approach that estimates the temporal relationship between climatic events and change-points in the rate of growth in human population as inferred from radiocarbon time frequency data. Our results do not support the climate-induced population decline hypothesis for three reasons. First, our Bayesian analyses suggest that the cooling event occurred after the start of the population decline inferred from the radiocarbon time–frequency record. Second, we did not find evidence showing a significant reduction of millet-associated dates occurring during the cooling climate. Third, we detected different magnitudes of decline in the radiocarbon time–frequency data in the inland and coastal regions, indicating that the even if cooling episodes were ultimately responsible of these population ‘busts’, their impact was most likely distinct between these regions. We discuss our results highlighting the long tradition of mobility-based subsistence strategy in coastal regions as a potential factor contributing to the regional differences we were able to detect.

The paper seeks to identify the role of cultural and social diversity in economic development. It starts by defining the terms that are critical to the analysis, including diversity, fractionalization, polarization, social diversity, cultural diversity and economic resources, as well as providing the most significant indexes thereof. The main body of the paper interprets the notions of cultural and social diversity in terms of being a valuable economic resource. Furthermore, it collects a vast body of literature to demonstrate the relationship between the cultural/social diversity and economic development with regard to adverse or positive impact on the latter. In regard to the negative impact of diversity, the paper identifies it in the area of social communication, social capital and networks, as it effectively causes a decrease in productivity and increase in social conflict and isolation. The positive link is demonstrated with examples in the areas of innovation, creativity, usage of complementary abilities and experiences, and their role in increasing productivity. The paper refers to numerous data sources, studies and indexes illustrating how the economic systems of various countries perform in the context of the paper’s subject-matter.

Cartels have a significantly negative impact on economic welfare. Anti-cartel competition law–such as the provisions of pt IV div 1 of the Competition and Consumer Act 2010 (Cth)–tries to tackle this negative impact through civil and criminal remedies. The prohibition of cartels is most commonly justified on economic grounds. However, reference is also often made to broader moral grounds for proscribing cartels–for example, it is commonly stated that cartels are deceptive, unfair or engaged in a form of cheating. This article advances a unified account of the moral status of cartels that integrates both economic and moral factors. It does so by emphasising the relationship of cartel behaviour to the moral duty to promote the common good. Cartels are wrong because they undermine the role of open and competitive markets as a salient response to an important social coordination problem in a way that leads to seriously harmful economic outcomes. This combination of factors supplies a robust justification for both civil and criminal sanctions in appropriate cases, thereby affording a principled foundation for the current framework of cartel regulation in Australia.

Place attachment is the development of a psychological and emotional bond between an individual and their environmental setting. While positive experiences in the residential neighborhood are central to ongoing develop-ment of people–place bonds, whether negative experiences erode place attachment remains unknown. In this study, we explore the relationship between crime victimization, social ties, neighboring behaviors, and place attachment in Brisbane, Australia. Using multilevel linear modeling, we examine whether negative experiences, specifically crime victimization, in the residential neighborhood affect residents’ attachment to place. We also explore whether this relationship is moderated by neighborhood social ties and/or interactions with neighbors. Results indicate that the negative impact of victimization in the residential neighborhood on place attachment is attenuated through frequent social and/or functional interactions with neighbors.

AbstractThis study investigated the moderating role of achievement motivation in the relationship between test anxiety and academic performance. Three hundred and ninety three participants (192 males and 201 females) selected from a public university in Ondo State, Nigeria using a purposive sampling technique, participated in the study. They responded to measures of test anxiety and achievement motivation. Three hypotheses were tested using moderated hierarchical multiple regression analysis. Results showed that test anxiety had a negative impact on academic performance (β = –.23; p < .05). Achievement motivation had a positive impact on academic performance (β = .38; p < .05). Also, achievement motivation significantly moderated the relationship between test anxiety and academic performance (β = .10; p < .01). These findings suggest that university management should design appropriate psycho-educational interventions that would enhance students’ achievement motivation.

Purpose – The purpose of this paper is to investigate the meditating role of psychological ownership which includes both organisation-based psychological ownership (OPO) and knowledge-based psychological ownership (KPO) on the relationship between affective commitment and knowledge sharing. Design/methodology/approach – This paper is an empirical study based on structural equation modelling, with a sample of 293 employees from 31 high-technology firms in China. Findings – The result indicated that affective commitment had a significant positive effect on OPO but no effect on KPO; OPO was positively related to both common and key knowledge sharing, while KPO exerted a negative impact on both; common knowledge sharing was positively related to key knowledge sharing; the relationship between affective commitment and key knowledge sharing was multi-mediated by OPO and common knowledge sharing. Originality/value – OPO and KPO play an essential role in transferring the effect of employees’ affective commitment to common knowledge sharing and key knowledge sharing, which unravels the blackbox of how effective commitment affects knowledge sharing.

With the development of science and technology, buying has become much easier. At the same time, however, impulsive buying has many negative consequences for college students, and the causes of impulsive buying should therefore be explored. To explore the relationship between social exclusion and impulsive buying and its underlying mechanism, this study used the Social Exclusion Scale, Self-Esteem Scale, Risk Preference Scale, and Impulsive Buying Scale to investigate the roles of self-esteem and risk preference in the relationship between social exclusion and impulsive buying among 768 college students (387 were female, Mage = 20.25 years). The results were as follows: (1) when controlling for gender, age, family monthly income, and monthly living expenses, social exclusion significantly and positively predicted impulsive buying; (2) self-esteem played a mediating role between social exclusion and impulsive buying; (3) risk preference moderated the relationship between the second half of the mediating path and the direct path. These results reveal the mechanism underlying impulsive buying in college students, that is, social exclusion will predict the decrease of college students' self-esteem, and low self-esteem will further predict college students' impulsive buying which is a way for them to gain a sense of self-worth. Relatively low risk preference can well alleviate the negative impact of social exclusion and low self-esteem on impulsive buying. What&rsquo;s more, these results have implications for impulsive buying interventions. Schools should aim to create a good peer atmosphere by making certain rules that help to reduce social exclusion and parents and education departments should cultivate students&rsquo; risk awareness to avoid risk behaviors in college students, such as impulsive buying behavior.

Abstract Background Over the last 50 years, there has been a growing interest in and use of contingency management (CM) for people who use substances. Yet, despite showing some level of efficacy (albeit only short-term) and being praised by researchers as beneficial and cost-saving, it continues to be underutilized by health care and service providers. Why that is remains unclear. Methods Recognizing a gap, we conducted a targeted analysis of a larger set of qualitative interviews conducted on the experience of health care and service providers with incentives (including prize-based CM) (n = 25). Results Four themes were identified during the analysis: 1) The specificities of prize-based CM, 2) The role of providers in administering prize-based CM, 3) The positive and negative impact on the relationship, and 4) The ethical concerns arising from prize-based CM. Overall, our findings are consistent with existing literature and suggest that providers are wary of using prize-based CM because they tend to value effort over success, support over reward, honesty over deceit, and certainty over probability and variability. Conclusion Our analysis offers additional insights into the experiences of providers who use prize-based CM and possibly some indications as to why they may not wish to work with this type of incentive. The question raised here is not whether there is enough evidence on the effectiveness of prize-based CM, but rather if this type of incentive is appropriate and ethical when caring for people who use substances.

An understanding of politics at workplace is of utmost importance as it is an inherent part of workplace activities. It is evident in processes such as decision making, allocation of resources. This study investigated the effect of perceived organizational politics (POP) on workplace attitudes such as job satisfaction, organizational commitment and turnover intentions. Further, the paper investigated the role of Leader-Member-Exchange (LMX) on the relationship between perceived organizational politics and workplace attitude. The hypothesized relationship was tested on a sample of 228 employees from Indian IT sector. Factor Analysis on POP suggested that variables can be summarized by two factors; Perceived Politics in organizational management (POP1) and Perceived Politics in co-workers (POP2). The findings suggest that there exists a negative relation between POP and workplace attitude. The results show that incase of the relationship between POP and workplace attitude, the part of organizational politics related to management has shown a significant negative impact on organizational commitment, job satisfaction, and a positive relation to turnover intention. With regard to the role of LMX in the relation between POP and workplace attitudes, results of LMX as a moderator have confirmed to the hypothesis.

Why are some states able to provide public goods and promote broad-based development whereas other states do not have the capacity to do any of these things? In search for an answer to this question, the past few decades have witnessed a radical increase in studies emphasizing a presumed negative role of ethnic fractionalization. Having been referred to as “one of the most powerful hypotheses in political economy,” the negative impact of ethnic fractionalization is now even so widely accepted that it has become a “standard” control in regressions explaining variation in political, social, and economic development. This chapter introduces, revisits, and confronts this so-called “diversity debit hypothesis,” focusing on the role of the Quality of Government. In particular, the chapter emphasizes the need to endogenize the relationship between ethnic fractionalization and public goods provision in a way that brings the state up front of the analysis as a social force in its own right, with the power to shape notions of “us” and “them” and, thus, development outcomes.
