海洋旅游地理和海上旅游资源利用

一、总观在社会再生产过程中,海洋环境的作用越来越大,在消遣方面也有所反映,而消遣是为恢复劳动力作准备的。海洋沿岸许多地区及其水域,在相应季节和有利的地方,其强烈的吸引力产生了两种利用类型之间的相互影响,这两种利用类型就是海上旅游和供人们度假时临时居住的景色最优美、气候最宜人的沿岸地区的开发。到这种地方去游憩虽然是古已知之的一种消遣方式,但游客成群结队作海上旅行还是近几十年才有的新现象。这就是本章要特别强调海洋旅游的原因,尤其是现在把“商务旅行”、“研究旅行”、宗教朝圣和消遣旅行都看作旅游(如世界旅游组织所解释的),突出这方面的内容更有必要。

三大前沿技术助力打造货运安全

从使用封条到使用卫星，货物的安全得益于科技的发展。新生的智能技术和检测技术为货运安全提供了新的解决思路，但再好的技术也要使用得当，否则也将一无是处。     

管理者在塑造高绩效的员工中的职责

管理者常常会认为员工工作良好。当然会有一两名员工表现不够好，但是员工总体上表现优良。工作差的员工在组织中待不久，因为管理者会在他们影响其他员工之前，迅速让他们离开组织。留在组织中的员工为了应得的薪水而付出相应的努力。他们可靠而有见识，值得信赖，而且没有怨言地进行工作，但是他们的业绩是否超出管理者的期望了呢？事实并非如此。

Who Gains from the Demographic Dividend? Forecasting Income by Age

Changes in the population age structure are known to influence the total income per person, but little is known about whether the changes are equally shared across the population or are concentrated on particular age groups and/or birth cohorts. The answer to this question has potentially important implications for income inequality, human capital investment, and fertility decision-making. We propose a new model of intergenerational transfers which distinguishes between the effects of changes in population structure and the effects of changes in family age structure. Using age-specific data from annual income and expenditure surveys of Taiwan between 1978 and 1998, we show that changes in age structure have had a very favorable effect on Taiwan's income growth. The gains are not equally shared by all age groups, however. Children and young adults have benefited the most, while the elderly have benefited the least. The population and family age structures have independent effects on per capita income; the effect of the population age structure is most important. Generational differences in per capita income are closely related to intergenerational differences in earnings, suggesting only a weak form of altruism. Finally, we predict that, on average, population aging will adversely influence the per capita income growth in Taiwan in the coming decades.     

Headship rates and the household formation process in Great Britain

"This paper looks at the changes in headship rates in Great Britain over the period 1960-1979, and attempts to explain them in terms of economic variables, such as real income and the real cost of housing. Such variables are found to be significant for some household types, but not for others. Notably, young single person household formation appears to be more supply constrained and to respond to appropriate supply variables." Furthermore, "some comparisons are made with similar studies done on similar data from the USA and France. These studies reveal a number of features in common, but also some differences, and these are commented upon."     

Waves of migration: a new situation

An attempt is made to forecast migration trends affecting those countries that were formerly part of the Soviet Union. "The new migratory trends are characterized by at least three fundamentally important elements: the ouster of the newly arrived population from the social niche that it had recently occupied, emigration from overpopulated regions, and growing emigration beyond the borders of the former Union."
