The stochastic approach to index numbers has been successfully applied to the estimation of inflation, the world interest rate and international competitiveness.?One distinct advantage of this approach is that it provides the whole distribution of the index, not simply one value. In this article, we extend the stochastic approach to the estimation of a stock market index. We demonstrate how this approach can be used to identify ‘redundant stocks’ that do not contribute significantly to the overall index.?For index tracking purposes, these stocks can be safely excluded. 相似文献

多伦多大学的OTA:历史及一个核心问题的讨论 总被引:1,自引:0,他引:1
多伦多大学的OTA(教学促进办公室)成立于2002年1月,其职责是改变多伦多大学传统的科研主宰型文化、帮助教师开发教学技能、并通过科学的晋升和薪酬机制确保科研型大学的教师在教学和科研之间建立有效的平衡。这必然涉及到一个最根本的问题:在高级职称的晋升中,卓越的教学业绩是否能与一流的科研成果相提并论?对这一问题,学生、教师、管理层持有不同的观点,西欧、澳洲、北美地区也有不同的做法。 相似文献

Motives for a secular pilgrimage to the Gallipoli battlefields 总被引:1,自引:0,他引:1
Pilgrimage is a journey to a non-substitutable site embodying the highly valued, the deeply meaningful, or a source of core identity for the traveller. Secular pilgrimage is an important yet under-researched sector of the tourism industry. Where the motives for religious pilgrimage are well documented, little is known of the motives for secular pilgrimages. This paper presents the results of an empirical investigation of one case of secular pilgrimage, the journey of Australians and New Zealanders to the Gallipoli battlefields in Turkey. Five distinct motives for visits to the pilgrimage site are identified – spiritual, nationalistic, family pilgrimage, friendship and travel motives – and differences in their importance noted across seven visitor groups. These motives share some commonality with the motives for religious pilgrimage, and conversely, with the motives for leisure tourism; yet, other motives are unique to the secular pilgrimage. Suggestions for future research on secular pilgrimage are provided. 相似文献

Volunteers at music festivals play a critical role in festival operation and success. As the music festival industry continues to grow, the ability for these large productions to effectively execute a large volunteer program is augmented. Volunteers from the 2013 Austin City Limits Music Festival were surveyed in regards to their self-image congruency, motivation, satisfaction, and intent to return as a volunteer at the festival. Analysis resulted in three distinct segments which has significant practical implications for festival management. Academic implications exist with the addition of self-image congruency and further discovery of volunteers in the festival and event industry. 相似文献

Extreme interannual variability of precipitation within Ethiopia is not uncommon, inducing droughts or floods and often creating serious repercussions on agricultural and nonagricultural commodities. A dynamic climate module is integrated into an economy‐wide model containing a detailed zonal level agricultural structure. This coupled climate‐economic model is used to evaluate the effects of climate variability on prospective irrigation and infrastructure investment strategies, and the ensuing country‐wide economy. The linkages between the dynamic climate module and the economic model are created by the introduction of a climate‐yield factor (CYF), defined at the crop level and varied across Ethiopian zones. Nine sets of variable climate (VC) data are processed by the coupled model, generating stochastic wet and dry shocks, producing an ensemble of potential economic prediction indicators. Analysis of gross domestic product and poverty rate reveal a significant overestimation of the country's future welfare under all investment strategies when climate variability is ignored. The coupled model ensemble is further utilized for risk assessment to guide Ethiopian policy and planning. 相似文献

Using data from the NLSY79, we structurally estimate a dynamic model of the life cycle decisions of young women. The women make sequential joint decisions about school attendance, work, marriage, fertility, and welfare participation. We use the model to perform counterfactual simulations designed to shed light on three questions: (1) How much of observed minority–majority differences in behavior can be attributed to differences in labor market opportunities, marriage market opportunities, and preference heterogeneity? (2) How does the welfare system interact with these factors to augment those differences? (3) How can new cohorts that grow up under the new welfare system (Temporary Aid for Needy Families) be expected to behave compared to older cohorts? 相似文献

ABSTRACTThe effects of gender on involvement in high-risk recreation have received limited research attention despite mounting evidence suggesting the learned interactions between people and places likely vary for men and women. The purpose of this study was to provide insights into how gender influenced the motivation-involvement relationship among whitewater recreationists on a Wild and Scenic River in California. Our results revealed the motivations of Risk, Escape, Learning, and Achievement/Stimulation positively influenced involvement in rafting activities. Although gender did not influence all dimensions of involvement, we found that identity expression varied between subgroups. Specifically, men were more likely to ascribe meaning to rafting than women because this activity allowed them to affirm and express their individual character. The implications emanating from this study advance theoretical understanding of the factors that influence enduring involvement and inform natural resource management decisions about maintaining the desired benefits of activities sought by nature-based recreationists. 相似文献
