The transition to agriculture is generally acknowledged to be the economic foundation for population growth over the last
10,000 years and for modern civilization itself. Dates for pristine transitions to agriculture have become a key input into
empirical work on economic growth over the very long run. We propose a model of the transition in which population and technology
respond endogenously to climate. The available data on the southwest Asian case, other cases of pristine transition, and cases
of non-transition are consistent with our model, but often inconsistent with rival explanations. In addition, our theory of
the origins of agriculture has implications for instrumental variable strategies that can be used in empirical research on
long run economic growth and development.

Using two studies, this article explores how a tendency to buy excessively for self relates to spending on one's pet. Existing research on excessive buying reports that these buyers spend money primarily on themselves. Excessive buying is the tendency to be preoccupied with buying and, consequently, to buy relatively more and more often than others. The first study, using a qualitative research approach, provides insights into the relationship of excessive buying for self and for pets. This study reveals that excessive buyers consider their pets as full family members and extensions of themselves. The second study, a national survey conducted via the Internet, provides a quantitative test of the relationship between excessive buying for self and spending on pets. Respondents who score high on an excessive buying index also tend to spend more on their pets for toys, food treats, clothing, accessories, and grooming products. 相似文献

Guanxi and leader member relationships between American managers and Chinese employees: open-minded dialogue as mediator 总被引:1,自引:0,他引:1
Effective open relationships with employees can help foreign managers rely upon and utilize the local knowledge of their employees.
One hundred and sixty-three Chinese employees from various industries in China were surveyed on their relationships (leadership–member
relationship and personal guanxi) with American and Chinese managers, their constructive controversy, that is, their constructive
controversy with them, and the job assignments and promotions received from their managers. Results support the hypotheses
that quality leader–member relationship and personal guanxi promoted their constructive controversy, which in turn facilitated
employees receiving challenging jobs and promotions. Results suggest that leader–member relationship and Chinese value of
guanxi may be important for enhancing their constructive controversy; this kind of open dialogue can be a foundation upon
which American managers can develop the confidence to give their Chinese employees challenging tasks and promotions.

Transatlantic Similarities and Contrasts in Rural Development Policies
The United States (US) and European Union (EU) share many general policy aims for rural areas, but they differ in the ways in which they try to achieve these aims. The principal difference lies in the role envisioned by agriculture in overall rural development. EU policies treat agriculture as a provider of public goods, and many of its 'rural' programmes target agriculture. In the US, very few Federal rural development programs are focused solely on agriculture. Differences of approach may be linked to different farm distributions, population densities, historical settlement patterns, and the historical policy process per se . In particular, in the US rural development policy does not cover the environment or income support to farmers; these are addressed through other programmes. In contrast, the EU classifies its agri-environmental programmes as rural development, claiming that more environmentally-friendly farm practices bring benefits to the broader rural economy. US State and local initiatives emphasize many themes found in the EU's Pillar II programmes, such as value-added or sustainable agriculture. Overall, although there are marked differences in the ways in which policies are implemented, the coverage of these policies in the EU and US is rather similar. 相似文献

Based on the theory of cooperation and competition, this study examines the relationships between cooperative goals, advice network, and team performance, and their boundary conditions. Based on multi-source data from 189 teams in a military organization, results indicate that cooperative goals positively influence team performance via advice network density. Moreover, advice network centralization moderates the relationship between advice network density and team performance. In addition, advice network centralization moderates the indirect effect of cooperative goals on team performance via advice network density. 相似文献

The authors investigated the effectiveness of online versus paper assignments using final examination scores in three cohorts of theory of finance. In particular, two cohorts were exposed to online assignments while another cohort was exposed to traditional assignments. The central result is that exposure to online assignments robustly leads to higher final exam scores, all else being equal. The authors also found a lower level of engagement as shown by low assignment completion rates for students exposed to online assignments. 相似文献

Technology has made changes in communication, lifestyle, and cultures, creating a new challenge to heritage sites. Technology can be the answer to connecting with local communities and tourists, reducing the gap between people and their inheritance, making it more understandable, creating awareness and value and eliminating time and space limitations. It can be used to communicate, interpret, teach, analyze, and make heritage accessible. And it can also be applied to make virtual reconstructions of what no longer exists. This paper analyzes the effect of technology at a heritage site, using the Abbey of Cluny as a case. This Abbey is a monument in France due to its importance during the Middle Ages as the monastic capital of Europe. Today, there are only a few traces of what the Maior Ecclesia used to be. New technologies were applied to rebuild what was destroyed with time using augmented reality and 3D reconstruction. Qualitative methods were used to describe what effects in visitors and promotion of the site were observable. 相似文献
