The costs and benefits of government purchases of goods and services from businesses are examined from the perspective of both public and private sector officials. Generally, governments see more benefits than costs, often because of fiscal stress. Businesses, especially newer, smaller firms are more likely to see more costs than benefits. The article concludes with ten projections for changes in public procurement systems by the year 2000. These are: (1) expansion of current vendor pools; (2) intergovernmental adoption of standardized forms and procedures for getting and staying on government vendor lists; (3) mainstreaming of purchasing into the government financial management decision-making loop; (4) more rigorous training requirements for government purchasing personnel; (5) greater use of public-private task forces to reform procurement policies and practices; (6) greater use of surveys inside and outside government to identify specific problem areas and structure reforms; (7) expansion of the auditing and contract monitoring section of purchasing departments; (8) extension of bidding/contract monitoring and evaluation requirements and procedures to subcontractors of prime government contractors; (9) greater efforts to include quality dimensions in cost estimates; and (10) more tension and litigation over “protectionism” in public procurement. 相似文献

Understanding why violence occurs disproportionately among black male adolescents has become a public health research priority due to recent increases in the rates of homicide and other violent crime in this population. This study examined independent, mediating, and moderating effects of family structure, attachment to parents, and family stress and conflict on self-reported fighting behavior. Subjects were black (n=163) and white (n=397) male 7th and 8th graders. Compared to white males, blacks were exposed to an excess of risk factors for violent behavior, including living in a single-parent household and higher levels of family stress and conflict. Although both groups reported similar levels of past-year fighting, black youth were more likely than whites to report attacking someone or being attacked by someone at school during the prior month. Controlling for age, area of residence, and other family characteristics, logistic regression analyses indicated that living in a nonintact family was a significant risk factor for violent behavior among black male youth, while attachment to parents was a significant protective factor for white males. Family stress and conflict was a risk factor for violent behavior cimmon to both groups of adolescents.This research was supported by the National Institute on Drug Abuse Grant No. R01 DA07037.Received Ph.D. from University of North Carolina at Chapel Hill, Health and Social Policy Research Division, P.

This study explored the implications of parents' traditional vs. egalitarian marital roles for girls' and boys' patterns of math and science achievement in 67 families with young adolescents. Marital roles were measured in terms of parents' relative involvement in child-oriented activities (e.g., in egalitarian families mothers and fathers participated equally in child-oriented activities). Findings revealed that girls from egalitarian families maintained a high level of achievement across the transition to the seventh grade, whereas girls from traditional families declined in math and science performance. For boys, no significant patterns emerged. Additional analyses revealed that egalitarian and traditional families differed in terms of absolute levels of paternal involvement, parents' sex-role attitudes, and indices of marital power. Our findings were consistent with a person-process-context model of development: Egalitarian and traditional contexts were characterized by different family processes and had different implications for boys and girls.This research was supported by a grant from the National Institute of Child Health and Human Development (RO1HD21050), Ann C. Crouter and Susan M. McHale, co-principal investigators.Research focuses on gender role socialization in the family.Research interests include children's and adolescents' family relationships.Research focuses on the links between parental work and family dynamics. 相似文献

Coping in adolescence: Empirical evidence for a theoretically based approach to assessing coping 总被引:2,自引:0,他引:2
The present study was designed to examine the reported Stressors and patterns of coping strategies used by adolescents and extend the 1989 work of Carver et al. by reporting internal reliability, factorial validity, and normative data on the COPE for a sample of middle adolescents. A sample of 484 ninth through twelfth graders (ages 14–18) attending a Laboratory High School participated in the study. The COPE inventory developed by Carver et al. in 1989 for use with college students, was administered with a battery of measures to all adolescent participants in their classrooms. Results indicated sufficient internal consistency for the measure and significant gender differences. Factor analysis of the COPE indicated that the subscales consistently fell into four factors rather than the traditional two (i.e., problem focused vs emotion focused). Implications for using the COPE in research on adolescent were discussed.Partial support for this project was obtained from the Society for the Psychological Study of Social Issues and by Illinois State University's Graduate Student Association, Graduate School, and Psychology Department.Received master's degree at Illionos State University.

Clinical experience suggests that women seeking abortion inhibit, either partially or completely, the normal process of fantasy about the fetus. To study this phenomenon more systematically, we compared five categories of fantasies in women (N=28)who wanted to carry their pregnancies to term with similar data in women (N=18)who did not want to carry their pregnancies to term and were seeking therapeutic abortion. All women desiring term pregnancies reported fantasies in multiple categories, and none denied having any fantasies concerning their unborn child. Sixteen of eighteen women seeking therapeutic abortion denied fantasy in any of the five categories tested: sex of the child-to-be, personal qualities and achievement, name of child, eye color, and imagining holding and/or nurturing the child. The remaining two women reported only fantasies about the sex of the child. The data obtained in this study tentatively support the hypothesis that women seeking abortion inhibit the process of fantasy formation about the fetus within them.Received M.D. from Yale Medical School in 1956.

Two measures of adjustment, the Erikson Psychosocial Stage Inventory and the Offer Self-Image Questionnaire, were administered to a sample of 450 working class Anglo-, Greek-, and Italian-Australian adolescents in years 9 and 11 of 9 Melbourne high schools. Anglo- and Greek-Australian adolescents scored similarly and significantly higher than Italian-Australians on a number of subscales, suggesting that culture conflict may be an influential factor in the adjustment of Italian-Australians, but not Greek-Australians. Significant differences between the minority groups, in favor of Greek-Australians, were interpreted as resulting from the relative differences in institutional support for and press toward assimilation of the two groups. 相似文献

The ongoing contact of adolescents with high school staff may provide an opportunity for the early identification and effective management of suicidal behavior. In this study, the knowledge, attitude, and experience of 80 high school professionals regarding adolescent suicide were assessed through semistructured personal interviews. Respondents identified more than 30 signs of potential vulnerability — manifestations of depression, verbal and written cues, isolation, and self-destructive behaviors. Among predisposing factors, those related to alienation within the family were most prominent. Other important risk factors were low self-esteem, difficulty in peer relationships, and economic or ethnic differences from other students. When suicidal behaviors occurred, respondents saw students and staff as attempting to be helpful; families were more often viewed as defensive. 相似文献

The need to accurately estimate the postmortem interval (PMI) has prompted research into factors affecting fly oviposition (i.e., oviposition and/or larviposition) on a corpse. Research efforts have focused on whether or not diurnally active flies oviposit during nighttime hours. This study reports that nocturnal oviposition (defined as occurring between 2100-0600 h CDST (Central Daylight Savings Time)) did not occur on freshly killed white rats or mice, on beef (fresh or aged up to 48 h), on freshly thawed pigs, nor, usually, on thawed pigs that were aged for up to 48 h. Limited oviposition did occur between 2100 and 2120 h on one bloated pig at a lighted rural site. Necrophilous flies were present and active at lighted and dark sites (urban and rural) before and immediately after sunset, but fly activity on the bait ceased within 50 min postsunset and did not resume until after 0600 h. These observations support other studies reporting that diurnally active flies do not oviposit during the nighttime. 相似文献

Bacterial species with high DNA sequence similarity to pathogens could affect the specificity of assays designed to detect biological threat agents in environmental samples. The natural presence of four pathogenic bacteria, Bacillus anthracis, Clostridium perfringens, Francisella tularensis, and Yersinia pestis and their closely related species, was determined for a large collection of soil and aerosol samples. Polymerase chain reaction (PCR) and gene sequencing were used using group-specific 16S rRNA primers to identify pathogens and related species, and pathogen-specific virulence genes. Close relatives of B. anthracis (B. cereus group species) were detected in 37% of the soils and 25% of the aerosol samples. The B. anthracis protective antigen (pag) gene or a close homolog was detected in 16 of these samples. For the other three pathogen groups, the frequency of detection was much lower, and none of the samples were positive with both the phylogenetic and virulence gene primer sets. 相似文献
