This article examines the general status in international law of certain fundamental human rights to determine the minimum "no derogation" standards, and then surveys a number of formal agreements between stages governing migration matters, while examining some of the standard-setting work undertaken by the International Labor Organization (ILO) and other institutions. Article 13 of the Universal Declaration of Human Rights, proclaims the right of everyone to leave any country, including his or her own. The anti-discrimination provision is widely drawn and includes national or social origin, birth, or other status. Non-discrimination is frequently the core issue in migration matters; it offers the basis for a principles approach to questions involving non-nationals and their methodological analysis, as well as a standard for the progressive elaboration of institutions and practices. As a general rule, ILO conventions give particular importance to the principle of choice of methods by states for the implementation of standards, as well as to the principle of progressive implementation. Non-discrimination implies equality of opportunity in the work field, inremuneration, job opportunity, trade union rights and benefits, social security, taxation, medical treatment, and accommodation; basic legal guarantees are also matters of concern to migrant workers, including termination of employment, non-renewal of work permits, and expulsion. The generality of human rights is due not because the individual is or is not a member of a partucular group, and claims to such rights are not determinable according to membership, but according to the character of the right in question. The individualized aspect of fundamental human rights requires a case-by-case consideration of claims, and the recognition that to all persons now certain special duties are owed.  相似文献

What strengths and talents make an outstanding child care worker? How can these qualities be measured? How can one predict whether an individual will succeed as a child care worker? The authors attempt to answer these questions by focusing on the "life themes" of highly rated child care workers and using a technique to measure these themes.  相似文献

Since 1970 the Philippine population program has made considerable achievements in its effort to curb the country's high fertility rate. The program presently aims to attain a population growth rate of 2.0% in 1992 and eventually achieve replacement fertility for the country by the year 2000. To achieve these rates, the program has set into motion the so-called "high scenario" targets of greatly increasing the overall rates of use-effectiveness of program methods of contraception. The program continues to be guided by policies implemented since its start, as well as by new ones in resonse to recent developments. Though the program continues to receive funds from international donors, the Philippine government's share in the funding has steadily increased.  相似文献

Empirical studies have shown that cyclical preferences are infrequent, but they have been less clear about why. Using thermometer ratings from nationally-representative samples of the U.S., we examine preferences for presidential candidates in order to determine what it is about them that leads to few cycles. Single-peaked preferences as usually construed (meaning that all of a set of preferences satisfy single-peakedness criteria) are, of course, rare. Yet we find a high degree of unidimensionality in the sense that for any given set of preferences, a relatively high proportion of the preference orders are consistent with single-peakedness. We also find that the highest amounts of unidimensionality often do not occur along partisan or left/right lines. Strong feelings for or against candidates, often not derived from an issue base, form the basis for the dimensionality discovered.We would like to thank Daniel Severance for programming the random model calculations and three anonymous referees, whose comments were very helpful in clarifying the presentation in this paper.  相似文献

Polls taken in late 1980 and 1984 varied by up to 20 pointsin the spread they reported between Democratic and Republicanidentifiers. We found three systematic and sizable differencesacross polls: polls that sample only voters, polls that emphasize"today" or the present in their question wording, and pollsthat are taken close to election day (at least in circumstanceslike those of 1984) tend to favor the party currently advantagedin the presidential race.  相似文献

Blockchain technology has received much attention in the media and there is an increasing interest amongst organizations within financial services due to the potential benefits. As blockchain-based systems are a nascent technology, the requirements of the technology need to be understood, to allow blockchain systems to be successfully integrated within financial service organizations. There are gaps in academic research in understanding how managers evaluate the value of a blockchain-based system. This study develops a model to explain manager resistance to implementing blockchain-based systems in financial services organizations. This research advances the theoretical understanding of managers’ perspectives on blockchain-based systems and models their resistance to blockchain technology.  相似文献

"Errors in disease classification can give misleading inferences for covariate effects when the probability of error is itself related to the covariates. More accurate inferences are possible using supplemental data on both true and fallible disease counts at various covariate levels. We present a method for incorporating such supplemental data into disease rate regression and use it to show that, although observed intercountry differences in European cervical cancer mortality rates are exaggerated by errors in death certification, they are not completely explained by such errors." The data concern Belgium, England and Wales, France, and Italy.  相似文献
