School Size and the Interpersonal Side of Education: An Examination of Race/Ethnicity and Organizational Context* 总被引:1,自引:0,他引:1
Robert Crosnoe Monica Kirkpatrick Johnson Glen H. Elder 《Social science quarterly》2004,85(5):1259-1274
Objectives. The purpose of this study was to extend research on the connection between school size and student outcomes by examining how school size was related to interpersonal processes and whether the interpersonal effects of school size varied by race/ethnicity. Methods. We applied multilevel modeling techniques to a sample of 14,966 students in 84 schools from the National Longitudinal Study of Adolescent Health. Results. Increasing school size was associated with decreasing student attachment to school and to teachers as well as extracurricular participation. Student attachment and teacher bonding diminished with increasing school size at a decreasing rate (reaching minimums in schools with between 1,700–2,000 students), but extracurricular participation dropped at a steady rate. These patterns did not differ substantially by race/ethnicity. Conclusions. The size of the educational institution influences interpersonal dynamics among actors in the institution and does so similarly across student groups. More generally, this research demonstrates the importance of organizational characteristics for social life. 相似文献

This article examines the theory and practice of rent control in the UK and elsewhere in order to contribute to the important debate on the future of the private rental sector in the UK. Our opposition to rent and eviction controls is unequivocal. We shall show that wherever rent control has been imposed the effects have been, at best, adverse and at worst, appalling. The effects on the quantity and quality of a housing stock can be so devastating that one Swedish socialist economist, Assar Lindbeck (1967) concluded: “In many cases rent control appears to be the most efficient technique presently known to destroy a city — except for bombing.” Controls which lead to an excess demand for housing foster unfortunate practices such a discrimination on various grounds other than willingness and ability to pay rent, and the creation of a black market. Rent and eviction controls also have a major impact on the mobility of labour. The encouragement to immobility can lead to the perpetuation of structural imbalances in an economy prompting rigidities which can have considerable economic and social costs. 相似文献

Second-, third-, fifth-, and sixth- grade children evaluated two hypothetical target peers in three provocation scenarios which differed as to the intent of a provocative act (Ambiguous, Accidental, Hostile). In addition to age and gender, evaluator-victim relationship was manipulated with children portrayed as being in a best friend, an acquaintance, or an enemy relationship with the victim, while the agent of the provocation was an unfamiliar peer. Evaluations were assessed in terms of attributions of aggressor's intentions, behavior response of the victim, evaluator's liking for victim, and evaluator's affect. Results indicated that older children evaluated aggressor's intentions and victim's behavior response more negatively than did younger children. Further, attributions of aggressor's intent significantly predicted the victim's subsequent behavioral response. Evaluator's affect was reported to be more negative when evaluating hostile provocation compared to accidental or ambiguous provocation and evaluators in acquaintance and enemy relationships with the victim reported liking the victim more after the provocation than before it occurred. Results are discussed in terms of the social relational and social situational influences on children's evaluations of peer interactions and the need to integrate these contextual factors in children's person perception research. 相似文献

The career decision state (CDS) was studied in relation to RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles in Self-Directed Search results among college students (86 women, 27 men). Three CDS dimensions measured by the Career State Inventory (CSI; certainty, satisfaction, and clarity) were examined as predictors of RIASEC primary and secondary constructs. Significant, albeit modest, zero-order correlations (p < .05) emerged between clarity and 3 secondary constructs (i.e., consistency, commonness, and coherence). Results of regression analyses indicated that CSI dimensions predicted 1 secondary construct (i.e., commonness). 相似文献

This paper provides a set of principles and ethics, developed in collaboration between Pacific‐ and Australian‐based researchers, to guide research practice in a project enabling the self‐reporting of children with disability in Vanuatu and Papua New Guinea (PNG). The paper presents both a summary of academic literature relating to these principles and ethics, as well as their succinct ‘translation’ into a set of action statements for researchers working with children with disability. The paper offers a base for further development by others to guide research practice and foster the autonomous participation of children with disability in developing countries. 相似文献

Overdose deaths, overprescribing of opioids, illicit production of fentanyl, a resurgence of methamphetamine and cocaine, and an epidemic of vaping‐related illnesses and substance use disorders cover the nation's headlines today, as they have for years. These problems are manifestations of commercial recreational pharmacology, the personally controlled use of psychoactive drugs that super‐stimulate brain reward for pleasure. While substance use and addiction have been known throughout history, the recent increasingly greater acceptance of commercial recreational pharmacology in the United States is exacting a toll on the public health of the nation. The most dramatic example is a decline in U.S. life expectancy, which fell three years in a row from 2016–2018 as a result of overdose deaths. 相似文献
