我国人口老龄化对教育行业的影响及对策

根据2000年的人口普查,我国老年人口在总人口中所占比重已经超过10%,中国已经进入老年人口型社会。如何积极开展人口老龄化问题的研究,是目前各行业都十分关注的问题;人口老龄化对我国教育行业的影响主要体现在教育需求市场、教师队伍建设,以及教育形式多样化等方面;构建终身教育体系,创建学习型社会,将是我国教育行业在老龄化社会中可持续发展的基本保证。     

20世纪三四十年代冀中人口流动与雇工

以人口流动和雇工水平为指标 ,通过对 2 0世纪 3 0年代保定 (清苑 )农村实证调查资料的研究 ,可以透视冀中乃至华北的农村现代化水平。 2 0世纪三四十年代冀中人口流动频率不高 ,数量有限 ,但已显现出由传统社会向现代社会过渡的变化特征。雇工劳动在旧中国冀中农村总体经济中仍然占较小比例。即使在这一小部分雇佣经济中 ,雇工物质生活悲惨 ,社会地位极低 ,还带有明显的人身依附关系的痕迹。从总体上看 ,农业雇佣经济的发展仍然很不充分 ,所以直至1 949年前农村雇工队伍与现代雇工阶级相比还有一定的距离

A Different Look at the “Population Problem”

The elite in Iran have been trained in Western economic ideas and committed to solving the problem of poverty either by Marxist or by neo-liberal methods. The author found that neither fit the real situation of people who live in traditional ways. Indeed, economic thought and modern practice are the causes of poverty. They have also imposed on people the false idea that population growth, rather than policies of domination, are the source of environmental damage and shortages.     

Population Dynamics: Poverty,Inequality, and Self-Regulating Fertility Rates

Population growth without a parallel increase in capital impoverishes any society and tends to deepen inequality. The system is dynamic because people who perceive or foresee contracting economic opportunity usually restrict family size. Worsening poverty feeds back into the loop to slow, then stop further population growth.     

A population size estimate of the finless porpoise,Neophocaena phocaenoides, from aerial sighting surveys in Ariake Sound and Tachibana Bay, Japan

We estimated the population size of the finless porpoise (Neophocaena phocaenoides) in Ariake Sound and Tachibana Bay of western Kyushu, southwestern Japan, from aerial sighting surveys using line transect methods. All 12 surveys were conducted from May 1993 to May 1994 (8 in Ariake Sound and 4 in Tachibana Bay). In addition to these, 14 surveys were also carried out to obtain information on porpoise occurrence in Tachibana Bay (5 surveys) and in neighboring Sumo Nada (5) and Yatsushiro Sound (4). In Ariake Sound, 225 porpoise groups (369 animals) were detected during all flights totalling 1,694.4 km. In Tachibana Bay, a total of 997.8 km was surveyed and 55 groups (290 animals) were sighted. However, no sightings were recorded in Sumo Nada (distance searched = 148.7 km) and Yatsushiro Sound (208.4 km). In Ariake Sound, few sightings were recorded from waters shallower than 5 m in depth. In Tachibana Bay all animals were detected from waters of less than 50 m depth. The population size was estimated as 1,983 animals in Ariake Sound (95% CI = 1,382-2,847), 1,110 in Tachibana Bay (95% CI = 642-1,920), and 3,093 in the 2 waters (1.3 individuals/km², 95% CI = 2,278-4,201).     

Bayesian estimation of the difference between two proportions

This paper is concerned with the problem of allocating a fixed number of trials between two independent binomial populations with unknown success probabilities θ₁ and θ₂, in order to estimate θ₁ - θ₂ with squared error loss. Introducing independent beta priors on θ₁ and θ₂, a heuristic allocation procedure is introduced and compared both with the optimal and with the best fixed allocation procedure. Numerical and asymptotic results of these comparisons are given and seem to indicate that there are situations when the best fixed allocation procedure performs almost as well as the optimal procedure.     

略论广西汉壮人口比例的变化与趋势

先秦以前,广西境内为壮族先民所居住。秦汉以后,汉族才逐渐迁入,并于明清以后在人口规模上超过壮族,形成了广西汉壮民族融合的独特形态。历史上汉壮人口比例(相对规模)的变化是影响广西汉壮民族关系的重要因素之一。
