As part of a larger ecological analysis of woman battering in Israel, this study examined the combined ability of selected cognitive and interpersonal measures to differentiate among couples in which women were battered and those in which they were not. The ability of these variables to predict men's physical violence and verbal abuse and women's verbal abuse was also executed. Results indicate that a combination of low marital adjustment, high levels of conflict over children, and more perceived self-control over one's life characterized violent men; low marital adjustment and high conflict over child rearing characterized battered women. Both men's and women's verbal abuse was moderately predicted by lower marital adjustment while men's physical violence was predicted by increased levels of conflicts with his partner over child rearing. These findings suggest the importance of marital relationship factors in domestic violence and highlight the need for further study of the interaction between perceived control and marital relationship problems in relationships where men physically abuse women.  相似文献

Two questions have predominated policy discussions about theallocation of federal aid to rural local governments duringthe last two decades: whether rural areas were getting their"fair share" and whether the aid was appropriately targetedto deserving communities. An analysis of data for 1972–1983shows that although the position of rural governments apparentlyimproved during the 1970s, the gains were principally due tosharply increased loans to rural areas, while urban areas benefitedfrom increases in grants-in-aid. Conversely, the aid reductionsof the early 1980s, by cutting into loans, which are less valuablethan grants, appear to have hurt rural areas less than urbanareas. A modest amount of income-targeting in federal developmentfunds was evident in the early 1970s, but it deteriorated duringthe following decade. By 1983 counties with higher incomes andmore satisfactory levels of public services received higherlevels of aid than places that might have been considered moreneedy. While the reasons for the generally diminished targetingare not clear, several possibilities, including the increasingimportance of loans as a federal aid mechanism, are considered.  相似文献

Is the extent of sex-based occupational segregation in U.S. state bureaucracies related to agency policy missions? Drawing on arguments by Lowi (1985), we contend that levels of sex-based occupational segregation in state bureaucracies vary depending on whether an agency's policy mission is distributive, regulatory, or redistributive. We employ data on the distribution of administrative and professional employees by sex in several types of state agencies across all 50 states for 1987–97. Our findings indicate high levels of occupational segregation among administrative cadres in agencies with distributive and regulatory policy commitments; however, professional workforces in these agencies have become less gender segregated over time. We find no evidence of occupational segregation among administrative and professional workforces in redistributive agencies. We argue that researchers need to examine the relationship between glass walls and other kinds of sex-based employment impediments, such as glass ceilings.  相似文献

Abstract: The collection efficiency of two widely used gunshot residue (GSR) collection techniques—carbon‐coated adhesive stubs and alcohol swabs—has been compared by counting the number of characteristic GSR particles collected from the firing hand of a shooter after firing one round. Samples were analyzed with both scanning electron microscopy and energy dispersive X‐rays by an experienced GSR analyst, and the number of particles on each sample containing Pb, Ba, and Sb counted. The adhesive stubs showed a greater collection efficiency as all 24 samples gave positive results for GSR particles whereas the swabs gave only positive results for half of the 24 samples. Results showed a statistically significant collection efficiency for the stub collection method and likely reasons for this are considered.  相似文献

Because of the increase of evidence of blood stains, that have been washed or cleaned in an attempt to mask the analysis of DNA profiles, there is also an increase in the use of presumptive tests on samples sent to laboratories. Some of the presumptive tests, used to identify blood and semen stains, could potentially affect the recovery of high molecular weight DNA from the samples, or extinguish them, especially those already present in small quantities. After the presumptive tests, often these samples are discarded. This study aimed to examine the possibility of obtaining a DNA profile from samples submitted for presumptive testing and cleaned with bleaches with and without chlorine. Two different protocols were conducted: (a) A unique sample of human blood in natura (5 μL), already typed through the DNA techniques with the genetic profile previously known (control), was distributed onto cotton fabrics and dried at room temperature. Four samples of fabric were macerated in saline solution and Coombs serum and then stored for three months (room temperature and freezer −20 °C). (b) Another sample of human blood, type A, in natura, already typed through the techniques of DNA (control) was used. Aliquots of 200 μL were distributed in: cotton, denim and synthetic fabric. The samples were dried at room temperature for 24 h. The blood stains in those fabrics (cotton, denim and synthetic) were then divided into three groups: unwashed, cleaned with chlorine bleach and cleaned with chlorine bleach and soap powder. The samples were again dried at room temperature for 24 h, before the use of luminol. The DNA were extracted with Chelex 100 and amplified with the Identifiler Kit (Applied Biosystems). The blood stains exposed to saline and Coombs serum had DNA profiles consistent with untreated samples (controls). This result shows that the experts should keep and store the samples treated with saline and Coombs serum for future DNA confrontation when necessary. Also discussed in this paper the pattern of blood stains after washing with bleaching solutions, as well as the quantity of DNA obtained from these samples.  相似文献

Oral fluid is an interesting alternative matrix for drug testing in many environments, including law enforcement, workplace drug testing, and drug treatment facilities. Performance characteristics of the FDA-cleared, qualitative, Cozart RapiScan Opiate Oral Fluid Drug Testing System (Opiate Cozart RapiScan System or Opiate CRS) were compared to the semi-quantitative Cozart Microplate EIA Opiate Oral Fluid Kit (Opiate ELISA) and to gas chromatography/mass spectrometry (GC/MS). The following oral fluid opiate cutoffs were evaluated: the GC/MS limit of quantification (LOQ) of 2.5 mg/l; 15 microg/l currently used for oral fluid testing in the United Kingdom (UK); 30 microg/l (Opiate CRS cutoff); and 40 microg/l, the proposed Substance Abuse and Mental Health Services Administration (SAMHSA) cutoff. Subjects provided informed consent to participate in this IRB-approved research and resided on the closed research ward throughout the study. Three oral codeine doses of 60 mg/70 kg were administered over a 7-day period. After a 3-week break, subjects received three doses of 120 mg/70 kg within 7 days. Oral fluid specimens (N = 1273) were analyzed for codeine (COD), norcodeine (NCOD), morphine (MOR) and normorphine (NMOR) by GC/MS with an LOQ of 2.5 microg/l for all analytes. MOR and NMOR were not detected in any sample; 26.5% of the specimens were positive for COD and 13.7% for NCOD. Opiate CRS uses a preset, qualitative cutoff of 10 microg/l; this is equivalent to 30 microg/l in undiluted oral fluid as the oral fluid collection process involves a 1:3 dilution with buffer. Sensitivity, specificity, and efficiency of Opiate CRS compared to Opiate ELISA were 98.6, 98.1, and 98.2% at a 30 microg/l cutoff and 99.0, 96.2, and 96.6% at a 40 microg/l cutoff. Compared to the much lower GC/MS LOQ of 2.5 microg/l, sensitivity, specificity and efficiency were 66.8, 99.3 and 90.7%. Increasing the GC/MS cutoff to the current UK level yielded performance characteristics of 81.5% (sensitivity), 99.3% (specificity), and 95.4% (efficiency). Using a GC/MS cutoff identical to the preset Opiate CRS cutoff yielded sensitivity, specificity, and efficiency of 88.5, 99.2, and 97.5%, respectively. At the proposed SAMSHA confirmation cutoff of 40 microg/l, sensitivity increased with little change in specificity and efficiency (91.3% sensitivity, 98.9% specificity, and 97.5% efficiency). Oral fluid is a suitable matrix for detecting drugs of abuse. Opiate CRS, with a 30 microg/l cutoff, is sufficiently sensitive, specific and efficient for oral fluid opiate analysis, performing similarly to Opiate ELISA at the same cutoff, and having performance characteristics >91% when compared to GC/MS at the proposed SAMHSA cutoff.  相似文献

The authors determined the six-month and lifetime prevalence of psychiatric disorders among 100 consecutively admitted female offenders to a prison, using Diagnostic Interview Schedule (DIS Version III) and found high prevalence rates of schizophrenia, major depression, substance use disorders, psychosexual dysfunction, and antisocial personality disorders. The prevalence rates of these disorders were significantly higher than those of the general population. The authors note the implications of their findings for treatment of women within the correctional system.  相似文献
