Fergany N 《The International migration review》1982,16(4):757-780
"The focus of this article is the impact of emigration on national development in labor sending countries experiencing wide-scale emigration, the main contention being that, due to the characteristics of contemporary labor movements among Arab countries, there obtains a contradiction between short term benefits and long term adverse effects. The article briefly defines development, then presents empirical evidence from the Yemen Arab Republic of the negative impact of labor emigration." 相似文献

As a guide for how to select a new executive director, a family agency adopted the search committee process from higher education. The approach included clarifying agency goals and the director's qualifications, a board-staff screening, and interviews held jointly with public representatives before final board selection. 相似文献

Characteristics of the population and economic measures that constitute traditional social indicators are compared with more recent “quality of life” measures to demonstrate that social indicators are always value statements at the policy level. The possibility of alternative perspectives is illustrated. It is suggested that an awareness of the assumptions implicit in any given indicator is as important as the data they provide. 相似文献

In this article, we first propose the modified Hannan–Rissanen Method for estimating the parameters of autoregressive moving average (ARMA) process with symmetric stable noise and symmetric stable generalized autoregressive conditional heteroskedastic (GARCH) noise. Next, we propose the modified empirical characteristic function method for the estimation of GARCH parameters with symmetric stable noise. Further, we show the efficiency, accuracy and simplicity of our methods with Monte-Carlo simulation. Finally, we apply our proposed methods to model the financial data. 相似文献

以TEECE创建的技术创新资源获取机制理论框架为研究起点,进行了开放式创新背景下的拓展。根据其对技术资源与商业化资源的划分,运用"占有机制"与"合约交易"2个关键变量,分别揭示在封闭式创新模式向开放式创新模式转变过程中,创新资源获取机制本质由创新资源控制权拓展为创新资源联合共享,具体表现为2个方面:一是技术资源占有机制由正式制度拓展为正式制度与非正式制度的集合,从而其作用机理从环境决定的外生变量,拓展为企业内生性的战略选择;二是商业化资源交易契约从合约交易拓展为合约交易与嵌入式交易。 相似文献

The authors examine the literature with respect to the pricing of initial public offerings and focus upon the relationship
of pricing to the structure and conduct of the investment banking industry. Using a data base of all share offerings undertaken
in the United States over a two and a half year period, the authors find that there is considerable evidence for the proposition
that large, prestigious, and well capitalised investment banks tend to price their share offerings at a higher absolute level
than those not meeting such characteristics. Using classical statistical methods, the authors find that the pricing strategy
of investment banks is connected to their affiliation with investment funds and unit trusts. The motives for such pricing
strategies, the authors argue, lie with the affiliation of investment banks with investment funds, suggesting that the pricing
of new share offerings may be a means of excluding retail investors from participating in the strong returns such issues exhibit. The authors raise legal and regulatory implications
of their findings in the context of the general consolidation observed within the investment banking industry.
