城市生活垃圾资源化与可持续发展

城市生活垃圾是城市居民日常生活丢弃的固体废物以及清扫的地灰和商业垃圾等城市代谢产物.城市生活垃圾具人文性、速生性、组成复合性、强污染性和城市化性等特性,因此也就具明显的两面性,即若生活垃圾未作处理,势必造成垃圾围城,严重污染环境,危害市民健康,阻碍城市可持续发展;若生活垃圾作了无害化、减量化、资源化处理,则净化环境,变害为利,变废为宝,促进城市可持续发展.人们大多只知城市生活垃圾有害的一面,对垃圾围城人人厌恶,却忽视或漠视生活垃圾资源化的可能性.随着人类社会的发展和科学技术的进步,人们应深刻认识城市生活垃圾具有可循环利用和再生利用的潜在价值,是地球上不断增长的资源,誉称"城市矿藏".本文着重探讨生活垃圾无害化、资源化处理对促进城市可持续发展的重要性.

道德实践的两个维度:自律与他律

本文从理论和实践两个层面探讨了道德的自律与他律的问题。认为道德是以自律性为基本特征的,但道德价值的根据是外在的、他律的,道德是自律与他律的统一。道德规范作用的方式既要有內省式自我约束又要有外在的社会约束,道德人格的培养也需要在自律养成与他律约束的矛盾运动过程申实现。公民道德建设要体现道德的自律与他律相统一的原则。

On Masking and Revealing the Culture of the Cross-Culturalist

There is a gulf between the analytic and experiential aspects of cross-culturalists' functioning that is reflected in the split between explicit scientific rules for studying the culture of others, while following an informal oral tradition for considering our own cultural makeup. This article discusses both a possible strategy for correcting this situation and the barriers that are likely to prevent such a correction. Structured cultural self-study procedures are presented as a possible resource in the continuing development of graduate students and professionals, and these have already proven highly effective in teaching cross-cultural psychology to undergraduates. Fostering commitments to standardized self-study and to applications of experiential learning is currently not likely to flourish due to complex academic and epistemic traditions, discussed as six cultural self-masking factors. A specific self-study protocol is offered to provide a beginning point for generating improved reflexive methods and for individual trial use. Through disciplined reflexivity, benefits might emerge in the form of better bias control in research, enhanced external validity, and a new theory about the interplay of investigators' self-knowledge and the conduct of cross-cultural research.     

Toward the development of an adolescent gambling problem severity scale

The development and initial psychometric properties of an adolescent gambling problem severity measure are described. The scale, based on a revision of the South Oaks Gambling Screen (Lesieur & Blume, 1987), was administered to 1,101 older (ages 15 to 18) Minnesota adolescents as part of a state-wide gambling survey. Study results indicated that the scale had moderate internal consistency reliability and was significantly related to alternate measures of problem severity for male subjects. Because the rate and severity of gambling among females was very low, the psychometric adequacy of the scale for females is not known at this time. The implications of study findings to the conceptual understanding of adolescent gambling problem severity as well as study limitations and future research needs, are discussed.Support for the study was provided by the Minnesota Department of Human Services and the Center for Addiction Studies, University of Minnesota, Duluth. The authors gratefully acknowledge the assistance from Robert Blum, Linda Harris, Durand Jacobs, J. Laundergan, Alan Mathiason, Brenda Miller, James Schaefer, school officials from the participating high schools, and interviewers who assisted with the telephone survey.     

The place of ego building work in psychotherapy with children

Ego building is essentially a name given to a variety of interventions used to support an ego hampered by regression or deviation. The term has its roots in the concept of ego support but evolved specifically as a technical term in contemporary ego psychology closely connected with the developmental theory of separation individuation. Using four vignettes of psychotherapy work with children all of whom suffered from unresolved conflicts and developmental interferences from the separation-individuation process, an attempt is made to illustrate the technical place of ego building in psychotherapy with children. It is suggested that the use of ego building, particularly verbalizing adaptive aims facilitates an alliance, supports a safety feeling and positive self-esteem. This contributes to providing a treatment experience that reduces over-stimulation and anxiety and frees the expression and understanding of aggression which ultimately promotes separation-individuation.in private practice.This paper was presented at the Conference on the Continuing Evolution of Psychoanalytic Thought: Infancy to Adulthood, N.Y.C., Nov. 1990., sponsored by the Committee on Psychoanalysis of the National Federation of Societies for Clinical Social Work.     

INTERGENERATIONAL MOBILITY IN THE REPUBLIC OF IRELAND: Does Gender Make a Difference?

This article compares in regression models the effects of occupational status of both fathers and mothers simultaneously upon the attainment of men and women in the Irish Republic. The sample matches male respondents from the 1973/1974 Irish Mobility Study with the labour active female sibling next closest in age. Since the analysis compares working siblings and each 'matched pair' shares the same family origin characteristics, the problems attendant upon using a sample originally of men only are partially avoided. The results advance beyond previous research since, rather than separate models by gender, models include parents and children of both genders, allowing direct rather than indirect evaluation of gender-based determinants of occupational attainment. Both fathers and mothers significantly affect children's attainment, in ways that vary by the child's gender. The results highlight the salience of mothers' attainment for their children and question the 'mainstream' model of equivalent mechanisms of occupational attainment for both genders. Models of social mobility that consider men and women as special instances of a general perspective provide the most fruitful approach for further development.
