爱和性合为性爱。爱是倾向性好的感情 ,人在青少年期萌生指向性的爱 ,最初为思念。性是异性间合而为一的欲求。爱和性随着生理的成熟一同到来。人对性是用身体来认识 ,对爱是用心来认识 ,二者殊途但终合为一 ,即性爱。性爱可以分为有爱的性交、无爱的性交和无性交的爱三种。爱与性交一方面具有相互的规定性 ,另一方面还有单方面的规定性。性爱是面向完全的、理想者的。性爱的原动力是理念 ,性爱前瞻性地志向于尚未存在的将来。  相似文献

Self-perception of aging and health among older adults in Korea   总被引:1,自引:0,他引:1  
The way that each individual perceives his or her own aging and health may be a key indicator of adaptation and well-being in old age. This study explored the determinants of self-perception of aging and health using 291 community-dwelling older adults in Korea (mean AGE=69.9). Older individuals with lower levels of education and economic status and various types of health problems (more chronic conditions, greater disability, poorer vision, and greater numbers of sick days) were found to have more negative self-perception of aging and health. In addition, a significant role of psychological factors was observed. For self-perception of health, sense of mastery was found to be a significant factor, and for self-perception of aging, neuroticism was observed to be significant along with sense of mastery. The mediating role of self-perception of health was supported that positive perception of health intervened the adverse effects of health problems on self-perception of aging. The findings demonstrate the important roles of psychological resources and subjective perceptions and suggest a need to consider them when planning interventions.  相似文献

Timing of first fatherhood was examined in a sample of 206 at-risk, predominantly White men, followed prospectively for 17 years. An event history analysis was used to test a model wherein antisocial behavior, the contextual and familial factors that may contribute to the development of antisocial behavior, and common correlates of such behavior, including academic failure, substance use, and early initiation of sexual behaviors, lead both directly and indirectly to an early transition to fatherhood. Having a mother who was younger at first birth, low family SES, poor academic skills, failure to use condoms, and being in a cohabitating or marital relationship predicted entry into fatherhood. Implications of the findings for prevention of and intervention with early fathering are discussed.  相似文献

Productive welfare: Korea's third way?   总被引:1,自引:0,他引:1  
How can the various pressures of economic globalisation and changes in the established welfare systems of the industrialised nations inform the development of the Korean welfare state? As the twenty‐first century dawns, Korea is confronted with a serious dilemma: How to adapt to globalisation and survive under worldwide competition and at the same time construct an effective egalitarian welfare state? The objective of this paper is to explore the future directions for the Korean social welfare system as it adjusts to economic globalisation. As it seeks a course between the social democratic welfare state model and the rising tide of the neo‐liberal welfare state, we pose the question: Is there a ‘third way’ for Korea? In trying to discern where the Korean welfare state is headed, it may be helpful to understand where it has come from and how it compares with the established welfare states in the industrialised nations.  相似文献

Experimental data were compiled for seven soybean varieties studied at four different locations in the U.S. for a period of one to three years. Three dose–response functions (linear, quadratic, and Weibull) were fitted, as appropriate, to the experimental data. Effects of acid deposition on soybean yields were estimated by combining variety-specific dose–response and production data. These calculations suggest that U.S. soybean production (2.2 billion bushels in 1982) would increase by 3.2 million bushels with a 10% reduction in 1982 hydrogen ion concentration levels in all counties where soybeans were grown, and by almost 70 million bushels with uniform improvement to pH 5.2. These estimates are based on many simplifying assumptions and are subject to several important sources of uncertainty explored in this study. The calculated changes are small in comparison with effects from other natural and anthropogenic stresses.  相似文献

Kinship and Population Subdivision   总被引:1,自引:1,他引:0  
The coefficient of kinship between two diploid organisms describes their overall genetic similarity to each other relative to some base population. For example, kinship between parent and offspring of 1/4 describes gene sharing in excess of random sharing in a random mating population. In a subdivided population the statistic F st describes gene sharing within subdivisions in the same way. Since F st among human populations on a world scale is reliably 10 to 15%, kinship between two individuals of the same human population is equivalent to kinship between grandparent and grandchild or between half siblings. The widespread assertion that this is small and insignificant should be reexamined.  相似文献

Nonparametric tests are proposed for the equality of two unknown p-variate distributions. Empirical probability measures are defined from samples from the two distributions and used to construct test statistics as the supremum of the absolute differences between empirical probabilities, the supremum being taken over all possible events. The test statistics are truly multivariate in not requiring the artificial ranking of multivariate observations, and they are distribution-free in the general p-variate case. Asymptotic null distributions are obtained. Powers of the proposed tests and a competitor are examined by Monte Carlo techniques.  相似文献

This paper investigates the factors influencing the disposition of cases in juvenile courts. The factors considered are the prior record of the offender, the nature of the offense, the recommendation of the probation officer, and the age of the offender. These four factors are essential components of the juvenile justice system and as such are perceived to be crucial for the understanding of the court's decision. A multivariate analysis of the data is undertaken using the method of log-linear analysis for hierarchical models. In contrast to other studies that have utilized the same method but with fewer variables, the model arrived at in the paper seems to be more accurate and suggests that while the offense and the prior criminal record are quite important factors, their influence on the disposition of cases is greatly bound by the age of the offender and the recommendation of the probation officer.  相似文献

The potential role of remote sensing in promoting the well-being of human settlements is identified. This was accomplished by formulating a closed loop system for habitat, wherein it requires a continuous feedback between the flow of information derived from remote sensing and the consequences of managerial decisions to control the basic characteristics of the human settlements, e.g. its environment, utilization of resources, early warning of natural hazards, etc. In addition, applications of remote sensing in both global scale and mesoscale for habitat are documented.  相似文献

Theoretical and practical aspects of dream analysis in family therapy are explored with case examples. The dream is considered tobe a disguised communication and it is used to aid in diagnosis and treatment. The dream is shown to be of special value with families who block communication or only appear to be cooperative. It is used to explore the unconscious elements of family life. Deciphering the dream helps to open new possibilities of communication within the family.  相似文献
