基于质量指数的经济增长转型测度研究——以深圳经济增长为例

中国经济如何实现由"速度型"向"质量型"转化是一个充满了探索性的问题,学者们从不同理论视角给予了广泛关注。而如何设计一个指数从定量角度测评速度向质量转化进程,以便直观地反映经济增长转型的度是理论研究不可或缺的部分。通过借鉴市场化指数的经济原理与设计思路,设计了质量指数作为测量经济增长模式转型的定量指标,定量测算了由"深圳速度"到"深圳质量"跨越的实现程度。实证测评结果显示:"深圳速度"已经开始向"深圳质量"转化,但人民生活水平提高的幅度与深圳经济发展水平存在较大的落差。以此为契机,为定量测度我国经济增长转型提供一个分析思路。

Types of Word-of-Mouth Messages: Information Search and Credence-Based Services

Word-of-mouth communication (WOMC) has been recognized as a powerful marketing communication medium and a credible information-gathering tool. To date, the various types of WOM messages have not been adequately studied, especially in credence-based services (CBS). Using the individual interview technique, this study fills this gap by describing the three types of WOMC messages in CBS information-gathering. The results contribute to the ongoing development of WOMC theory and also advance management's understandings of the types of WOMC messages in the CBS information-gathering process.     

National culture,leadership and citizenship: Implications for cross-cultural management

Continued globalization is raising the level of diversity within hospitality organizations as well as the likelihood that leaders will manage those from varying national cultures. Previous research has found that cultural congruence between leaders and stakeholders (i.e., from the same or different national cultures) impacts a variety of variables including perceived leadership style, satisfaction and trust. This study extends this line of research by investigating the relationship between cultural congruence, perceived leadership style, leader–member exchange (LMX) and employee citizenship behaviors. Using a highly diverse sample of 520 members of congruent and incongruent dyads from 66 countries working for 2 large cruise lines and 2 subsidiaries, multivariate analysis of variance (MANOVA) was used to test the relationships. It was determined that cultural similarity impacted employee perceptions of LMX relations and organization citizenship behaviors, but not leadership style. The results of the study provide strategies for cross-cultural management in the hospitality industry.     

岷江上游森林生态系统服务条件价值评估

针对岷江上游森林生态系统服务现状,采用条件价值评估法(CVM),以支付卡形式设计了374份调查问卷,调查了岷江流域居民对上游森林生态系统服务的支付意愿(WTP)。结果表明:岷江流域60.80%的居民家庭对岷江上游森林生态系统服务存在支付意愿,平均支付意愿为每户每年44.00元。按照岷江流域现有家庭数量计算,岷江上游森林生态系统服务价值每年是5 507.48×104元。利用二元Logistic模型,对支付意愿与个人社会经济变量进行了较为详尽的分析,并对影响居民支付意愿的主要因素作了环境经济学解释。

The effects of the Works Progress Administration's anti-malaria programs in Georgia 1932–1947

From 1900 to 1950, malaria rates declined rapidly in the southeast United States. At its peak, malaria infected over 30% of the population. Malaria declined over the period for several reasons: improvements in public infrastructure; development of new insecticides; improvements in agriculture that promoted drainage; increases in incomes; and changes in migration patterns. This paper focuses on public works constructed by the Works Progress Administration (WPA) during the 1930s and subsequent interventions during the 1940s. To estimate the relationship between these malaria programs and malaria rates, I construct a panel of annual county level malaria rates in Georgia from 1932 to 1947. Between 1932 and 1940 the malaria rate in counties that received WPA malaria projects fell from 25.9 deaths per 100,000 to 5.3 deaths per 100,000. The empirical estimates suggest that WPA malaria projects led to 9.1 fewer deaths per 100,000 or roughly 44% of the observed decline in treated counties. Additional public works constructed by the MCWA during World War II, and the introduction of DDT after 1945 completely eliminated malaria in Georgia by 1947.     

Updating Seminal Studies of Entrepreneurial Researchers in the 60's to the 90's

ABSTRACT

As early as the 1960's various researchers of African and Nigerian small business and entrepreneurship like P. Schatz, P. Kilby, J. Harris and M. Rowe, A. Ale, W. Nafziger, J. Wilde and others have been debating. Their argument is with attempt to trace and identify the factors which continue to stunt the growth and development of small and medium enterprises (SME's) and entrepreneurship in Africa and in Nigeria. The investigations carried out by these and other researchers on this subject should be accepted as pertinent and justifiable. This is especially so, in consideration of the abundant availability of both natural and mineral resources for use as raw materials within the continent. In addition, enormous amount of funds has been expended alongside immense attention and effort by governments towards the development of small-scale industries and entrepreneurship. A number of external factors therefore, like inadequate infrastructure, scarcity of machines, spare parts and equipment, lack of information, paucity of raw material supplies and problem with government policies and officials as well as cultural factors have been identified among the most serious obstacles. Internal factors such as poor organizational planning, problems of succession, inadequate re-investment of profits, lack of capital and poor managerial skills have also been noted by other researchers as main growth barriers. This research updated earlier work done by these different groups of researchers with reference to the small plastics manufacturing sector in Nigeria to see if there have been any changes in the last 10-30 years of study. The findings revealed that there has hardly been any significant difference in terms of improvement especially of external constraints observed between the 1960's and 1990's. However, the study found a number of progressive internal improvements being applied in other small plastic manufacturing businesses. Recently, some small plastics manufacturing entrepreneurs on their own initiative have learned to create and innovate various ways of coping with constraints facing their businesses independently.     

Cervical cancer prevention in Morocco: a model-based cost-effectiveness analysis

Abstract

Objective: Cervical cancer is a huge public health issue in Morocco which represents the second most frequent and fatal cancer among women. Countries that have not yet introduced the HPV vaccine could benefit greatly, but before implementation it is necessary to perform country-specific economic assessments that include current screening practices.

Methods: A Markov model was developed to simulate the natural history of HPV and cervical cancer so as to calculate the long-term health benefits and costs of HPV vaccination and current screening by visual inspection with acetic acid (VIA). Starting from a previous transition probability matrix used for a model from Spain, the present model was calibrated to cervical cancer incidence from Morocco. Cost survey data was used to estimate the cost of screening and clinical procedures from the public healthcare perspective. Incremental cost-effectiveness ratios were calculated as 2018US$ per additional year of life saved (YLS) and both costs and health outcomes were discounted at 3%.

Results: The expected reduction in lifetime risk of cervical cancer for current screening would be 14% at a cost of US$551/YLS compared with no intervention, assuming VIA every 3 years in women aged 30–49 at 10% coverage. HPV vaccination of pre-adolescent girls at 70% coverage would reduce the lifetime risk of cervical cancer by 62% at a cost of US$1,150/YLS, compared with no intervention. When implementing HPV vaccination in combination with current screening, vaccination would be dominated, and the combined strategy would provide a 69% reduction at a cost of US$2,843/YLS, compared with screening alone. Current screening would be dominated by vaccination when screening coverage is higher than 15%, whereas the combined strategy rapidly exceeds US$4,000/YLS.

Conclusions: HPV vaccination could be highly effective and cost-effective in Morocco. Current screening would be good value for money compared with no intervention, but scaling-up screening coverage would make it inefficient compared with vaccination.
