Family therapy has not served battered women well. Men use battering to silence women; a woman, once abused, is unlikely to speak honestly in a situation where doing so invites re-abuse. Therefore we rarely perceive, label or deal effectively with male violence toward women, a major source of marital disruption. To stand with the oppressed, we must learn to detect the possibility of abuse, separate the couple, and refuse to collude with criminal acts.  相似文献

以19个两系籼梗杂交水稻组合为试验材料,应用通径分析法从形态学和生理学的角度分析了影响籼梗杂交水稻籽粒增重的因素。结果表明稻穗上、中、下部籽粒表现强、中、弱势粒灌浆生长特点。单株颖花数目与总干物重的相对比例、收获指数对稻穗不同粒位的籽粒增重产生较大的直接效应。单株总干物重对不同粒位千粒重的影响产生较大的间接效应。单株枝梗总干重对中、上部籽粒增重产生较大的直接效应,但对下部籽粒增重产生较大的直接负效应。此外,中、上部一次枝梗干重与其着生的颖花数目的相对比例,下部一次枝梗干重相应对其籽粒增重产生较大的直接效应。对提高两系籼梗杂交水稻籽粒增重进行了讨论。  相似文献

TESTAMENTARY BEHAVIOR:   总被引:1,自引:0,他引:1  
Content analysis and qualitative analysis of all 319 last wills that were filed in Providence Probate Court, 1985, revealed that about ten percent of the testators used testamentary material, disinheritance or altruism to express their individuality. About 42 percent of the wills were personalized directly in other ways. Forty-eight percent displayed indirect influences of family, friends and community. Less that ten percent displayed primary influences of attorneys, banks, nursing homes, governments, religions or other organizations. In the light of these findings, while none of the three major theoretical positions on testamentary behavior prevails, the individualist position is manifested more often than is the family-community position. Both of these positions are manifested much more often than is the legalist position.
These findings are related to the work of Emile Durkheim and to contemporary sociological theories of the family, community and law.  相似文献

Dental caries in children is now recognized as a preventable disease. The use of fluoride and sealants has produced a major reduction in caries prevalence among school aged children in the United States and other countries. A portion of the child population who are educationally and socioeconomically disadvantaged are not fully receiving these benefits. Public policy, insurance and medicaid groups must be made aware of these preventative measures and strategies developed to implement them.  相似文献

SUMMARY. We now have over 16 years experience of child protection arrangements that include the attendance of police officers at child protection conferences. This article attempts to review that experience and critically assess the police role at conferences in the light of the Department of Health's Working Together, Particular attention is paid to the nature of information made available by the police to child protection conferences.  相似文献

Philadelphia, then and still one of the worst governed of America’s badly governed cities, was having one of its periodic spasms of reform. A thorough study of causes was called for. Not but what the underlining cause was evident to most white Philadelphians: the corrupt semi-criminal vote of the Negro Seventh Ward…. Would it not be well, to elucidate the known causes by a scientific investigation?… With my bride of three months, I settled in one room over a cafeteria run by a College Settlement, in the worst part of the Seventh Ward. We lived there a year, in the midst of an atmosphere of dirt, drunkenness, poverty and crime. Murder sat on our doorstep, police were our government, and philanthropy dropped in with periodic advice. (DuBois, 1968/1975: 194–5 also in Logan, ed. 1944: 42) What had been borne into me during my book studies was my utter ignorance of the manual-working class, that is, of four-fifths of my countrymen…. How was I to get an opportunity of watching, day by day, in their homes and in their workshops, a sufficient number of normal manual-working families to enable me to visualize the class as a whole; to understand what was meant by chronic poverty and insecurity of livelihood. (Webb, 1926: 146–7)  相似文献

The Latack-Dozier (1986) model of career growth through job loss was examined using a sample of 515 involuntarily displaced professionals. Results supported the model and identified variables most predictive of career growth for men and women. The results also partially supported the hypothesis that men and women rely on different forms of social support after job loss. The Latack-Dozier model is discussed in light of the findings. In addition, implications for dismissed workers, for career development specialists, and for practitioners are discussed.  相似文献
