This study proposes and demonstrates an analytic paradigm based upon a substantive categorization of a set of inmigration correlates. It exemplifies the notion of categorizing, analyzing according to the categorization, and subsequently discussing the phenomenon in more depth. The paradigm has 2 steps: 1) the variables are categorized according to the cells resulting from the intersection of a preferably small number of nominal dimensions and 2) the data are analyzed, directly anchored in the prior categorization. The data used is Israel's 1983 census macro-data gathered from the Central Bureau of Statistics for the Israeli towns with populations of at least 5000. The authors defined 6 variables as push variables and 4 as pull variables. Results of the regression employing push variables show that 4 variables accounting for 72% of inmigration were found to significantly predict inmigration: 1) unemployment, 2) percentage of Asians-Africans, 3) town size, and 4) religiosity. Within the pull classification, the regression analysis reveals that 2 of the 4 variables explain 31% of the inmigration variance: 1) educational level (26%) and 2) income (5%). The 1st regression analysis on the 2nd dimension shows that the percentage of Asian-African origin and town population size account for 32% of the immigration variance. In the 2nd regression analysis, unemployment explains 48% of the inmigration variance and educational level explains 8%. In the 3rd regression, only home crowding explains a significant amount of the immigration variance (19%). Results of a multiple regression analysis show that unemployment level, percentage of Asian-Africans, population size, and level of religiosity account for 72% of the inmigration variance. Thus, the characteristics of a town inmigrating (push variables) are demographic, economic, and social. However, the attractive features of a town are only economic. Among all economic factors, unemployment is primary. In addition, not only are both percentage of Asians-Africans and population size significantly deflective of inmigration, but each also plays a separate and independent role. 相似文献

International labor standards take the form of Conventions and Recommendations that embody the agreements reached by a 2/3 majority of the representatives of Governments, Employers, and Workers of International Labour Office (ILO) member states. Originally designed to guard against the danger that 1 country or other would keep down wages and working conditions to gain competitive advantage and thereby undermine advances elsewhere, international labor standards have also been inspired by humanitarian concerns--the visible plight of workers and the physical dangers of industrialization and by the notion of social justice, which embraces wellbeing and dignity, security, and equality as well as a measure of participation in economic and social matters. ILO standards apply to workers generally and therefore also to migrant workers, irrespective of the fact that the general standards are complemented by standards especially for migrant workers. The social security protection of migrant workers has been dealt with in ILO instruments primarily from the angle of equality of treatment but also from that of the maintenance of acquired rights and rights in course of acquisition, including the payment of benefits to entitled persons resident abroad. The ILO Conventions on migrant workers and the Recommendations which supplement them deal with practically all aspects of the work and life of non-nationals such as recruitment matters, information to be made available, contract conditions, medical examination and attention, customs, exemption for personal effects, assistance in settling into their new environment, vocational training, promotion at work, job security and alternative employment, liberty of movement, participation in the cultural life of the state as well as maintenance of their own culture, transfer of earnings and savings, family reunification and visits, appeal against unjustified termination of employment or expulsion, and return assistance. ILO's supervisory mechanism consists basically of a dialogue between the ILO and the Government that is responsible for a law, regulation, or practice alleged to be in contravention of principles it voluntarily accepted. The control machinery is often set in motion by workers' organizations. The UN General Assembly is currently elaborating a new instrument designed to cover both regular and irregular migrant workers and their families. 相似文献

The arguments for and against policy measures designed to increase birth rates in European countries are reviewed. The author concludes that the deterioration of the environment associated with the growth of population in developed countries outweighs any arguments in favor of policy measures to increase fertility. 相似文献

From making to being the excuse: An analysis of deception and verbal/nonverbal issues 总被引:1,自引:0,他引:1
Excuse-making is defined, and the issues of deception and verbal/nonverbal presentations are discussed in regard to the excuse process. Subsequently, the deception and verbal/nonverbal issues are described in greater detail in the context of whether the excuse occurs temporally after a negative outcome (retrospective), before a negative outcome (anticipatory), or as part of the characterological makeup of the person (incorporated). Going from retrospective to anticipatory to incorporated excuses, it is concluded that the role of nonverbal factors increases. Likewise, in the progression from making to being the excuse, it is argued that self- and other-deception also become more pervasive. 相似文献

"A mixed model is proposed for the analysis of geographic variability in mortality rates. In addition to demographic parameters and random geographic parameters, the model includes additional random-effects parameters to adjust for extra-Poisson variability. The model uses a gamma-Poisson distribution with a random scale parameter having an inverse gamma prior. An empirical Bayes approach is used to estimate relative risks for geographic regions and annual rates for demographic groups within each region. Lung cancer in Missouri is used to motivate and illustrate the procedure." 相似文献

Elective single mothers are adult, unmarried women who intentionally become mothers. This study utilized longitudinal data about 17 Caucasian, elective single mothers and their children to identify fathers' roles in these families, and to understand children's views of their fathers. These single mothers and their children resided for the first six years of the children's lives in father-absent households. By age six, most of the children had ghost fathers, whom they had never met or knew little about. The data suggest that the father often becomes a family secret, and that children may blame themselves for their fathers' absence. 相似文献
