A comparison of gang and individual rape incidents.

This study examined differences between gang and individual offender rape incidents reported to the Chicago police. Analyses showed that victims and offenders in gang rape incidents were younger, more likely to be unemployed, but not different in marital status or race than victims and offenders in individual rapes (e.g., single offender, single victim crimes). Gang rapes were characterized by more alcohol and drug involvement, fewer weapons, more night attacks, less victim resistance, and more severe sexual assault outcomes compared with individual rapes. Regression analyses revealed distinct correlates of physical injury outcomes for gang and individual rape incidents. Implications for treatment and prevention of these types of assaults are discussed.

Secondary victimization of rape victims: insights from mental health professionals who treat survivors of violence.

Rape victims may turn to the legal, medical, and mental health systems for assistance, but there is a growing body of literature indicating that many survivors are denied help by these agencies. What help victims do receive often leaves them feeling revictimized. These negative experiences have been termed "the second rape" or "secondary victimization." If indeed secondary victimization occurs, then these issues may be raised in rape survivors' mental health treatment. In the current study, probability sampling was used to survey a representative sample of licensed mental health professionals about the extent to which they believe rape victims are "re-raped" in their interactions with social system personnel. Most therapists believed that some community professionals engage in harmful behaviors that are detrimental to rape survivors' psychological well-being. Implications for future research on secondary victimization are discussed.

An unusual case of pseudo rape.

A case has been reported which adds a new and unusual dimension to false rape allegation and gives a heretofore unknown motive for a woman to claim a bogus rape. A female newspaper reporter entered a hospital, stated falsely that she had been sexually assaulted, allowed herself to be interviewed and then examined by the author, and accepted and took medication, all because she wanted to "find out how a rape victim is treated at the new Rape Center and I was pretending to be a rape victim." Rape center workers must be alert to spurious claims of unprincipled and deceitful women.

Attitude towards rape: a comparative study among prospective physicians of Malaysia.

The global statistics reveal that at least one in every five women experiences rape or attempted rape during her lifetime. Rape myths encompass a set of (false) beliefs. Adolescents have high rates of rape victimization than other age groups. Rape myths among health care providers may have a negative influence on proper care of the victims. A total of 422 medical undergraduates of both sexes, studying at two Malaysian Institutes took part in the study. A validated questionnaire used in an earlier study was used for the present study, with a slight modification of scoring system. The age range of medical students was 17 to 34 years: mean +/- SD of men and women, were 20.6 +/- 2.1 and 20.3 +/- 2 respectively. Only about 19% of women and 11% of men had a very good positive attitude. Nearly 1/3 of women and 1/2 of men had a more negative attitude. On the whole the average total score of women was significantly higher (p=0.0004) than men. Nearly 50% of candidates with a village background carried more negative attitude. Violence against women is a significant public health problem. The major revelation of the present study is that only less than 20% of the medical undergraduates had a more positive attitude towards rape. Introduction of courses on 'sexual violence' in medical curriculum is likely to increase a) awareness, b) skills in management, c) in providing support and care for the victims and d) in implementing preventive actions.

Rape and homosexuality.

The relationship between rape and homosexuality can be best understood by studying male rape. Offender(s) may deny homosexuality and confuse an aggressive active behaviour with a masculine (even macho) behaviour. They may project their homosexual feelings onto the victim. In the aftermath of rape, the victim may be ashamed of having lost control and may question himself about his real sexual identity. An aspect of female or male rape by a group of males may be an attempt to annihilate latent homosexual tendencies existing between members of this group. Surprisingly, in the short term, post traumatic disorder related to rape and pre-existing psychiatric disorder may develop separately, without substantial interaction. In the famous case of Schreiber described by Freud, homosexuality is assumed to play an important role in the development of paranoid schizophrenia. Cases in which schizophrenic patients (of both sexes) imagine being raped by a member of the opposite sex, may possibly challenge this opinion.

Empathy with a rape victim: the role of similarity of experience.

The purpose of this study was to replicate and extend a prior investigation (Barnett, Tetreault, Esper, & Bristow, 1986) in order to clarify the role of similarity of experience in women's empathy with a rape victim. Women who were identified as having been raped rated themselves as more empathic with, and more similar to, a rape victim patient presented on videotape than did nonrape control subjects who had been matched on level of dispositional empathy. However, no difference was found between the two subject groups in their responses to a videotaped patient whose personal problems were unrelated to the experience of rape. In addition, subjects generally rated the rape victim patient as less emotionally stable than the patient whose personal problems were unrelated to rape. Alternative interpretations of the major finding of this study are discussed.

How nursing students' reactions to rape victims are affected by a perceived act of carelessness.

This experiment focused on how reactions to a rape victim would be affected by a perceived act of carelessness. The subjects were 116 graduating baccalaureate nursing students, 31% of whom were registered nurses. All subjects read a vignette of a rape in which the victim was described as having driven to a drugstore on a legitimate errand. Subjects were randomly assigned to read one of four versions, in which the victim either locked or failed to lock her car door (carelessness manipulation) and in which the rape occurred at 10:00 P.M. or midnight. All subjects evaluated the victim on a series of 11-point rating scales, and the data were analyzed by means of 2 x 2 analyses of variance. As hypothesized, subjects in the unlocked condition (compared to those in the locked condition) liked and identified with the victim significantly less, and attributed significantly more carelessness and responsibility for the rape to her. There was no significant main effect for the time the rape occurred. Use of vignettes as an unobtrusive measure of attitude toward rape, and implications for nursing education and practice are discussed.

Political rape as persecution: a legal perspective.

The use of rape as a tool of persecution is not new, but recognition of the political rape of women as a violation of internationally protected human rights and as a basis for political asylum is. Over the last several years, a number of advances have been made, including human rights instruments that recognize the need to protect women from rape and other sexual abuse; guidelines from the United Nations High Commission for Refugees and several countries that acknowledge the political nature of rape and the difficulties experienced by women attempting to assert claims to asylum based on rape or other sexual abuse; and a number of important decisions by individual governments to provide protection to survivors of rape. Legal advancements for women in this area have depended largely on the assistance of medical and psychological experts who have been able to educate adjudicators and advocates on the effects of sexual harm, provide expert testimony in individual asylum cases, and provide critical treatment and support to survivors as they work their way through the process of obtaining legal protection.

Improvement of rape (Brassica napus) plant growth and cadmium uptake by cadmium-resistant bacteria.

This study focuses on the screening of cadmium-resistance bacterial strains from heavy metal-polluted soils to examine their plant growth promotion and cadmium uptake in rape (Brassica napus). A large number of bacteria were isolated from heavy metal-polluted soil in Nanjing, China. Thirty isolates showing cadmium-resistance on Cd-amended medium were selected and evaluated for their potential to solubilize cadmium carbonate in solution culture. Atomic absorption spectrometer analysis showed variable amounts of water-soluble Cd (ranging from 24 to 117 mg l(-1)) released by the cadmium-resistant bacterial strains from cadmium carbonate. Qualitative analysis confirmed the presence of indole acetic acid as the auxin in the culture of these cadmium-resistant bacterial strains. Root elongation assay conducted on rape under gnotobiotic conditions demonstrated increases (up to 31%) in root elongation of inoculated rape seedlings compared to the control plants. Based upon cadmium-resistance, bio-activation of CdCO3 and growth-promoting activity, three isolates were selected for promoting plant growth and uptake of cadmium from cadmium-amended soil in pot experiments. Inoculation with the isolates was found to increase root dry weight (ranging from 8% to 20%) and shoot dry weight (ranging from 6% to 25%) of rape. An increase in cadmium content varying from 16 to 74%, compared to the non-inoculated control, was observed in rape plants cultivated in soil treated with 100 mgCd kg(-1) (as CdCl2) and inoculated with the isolates. The bacterial isolates were also able to colonize and develop in the rhizosphere soil of rape after root inoculation.

Effects of microcystins on the growth and the activity of superoxide dismutase and peroxidase of rape (Brassica napus L.) and rice (Oryza sativa L.).

Microcystins are naturally occurring hepatotoxic cyclic heptapeptides produced by some toxic freshwater cyanobacterial species. In this study, crude extract of toxic cyanobacterial blooms from Dianchi Lake in southwestern China was used to determine the effects of microcystins on rape (Brassica napus L.) and rice (Oryza sativa L.). Experiments were carried out on a range of doses of the extract (equivalent to 0, 0.024, 0.12, 0.6 and 3 microg MC-LR/ml). Investigations showed that exposure to microcystins inhibited the growth and development of both rice and rape seedlings, however, microcystins had more powerful inhibition effect on rape than rice in germination percentage of seeds and seedling height. Microcystins significantly inhibited the elongation of primary roots of rape and rice seedlings. Determination of the activities of peroxidase and superoxide dismutase demonstrated that microcystin stress was manifested as an oxidative stress. Using ELISA, microcystins were examined from the extract of exposed rape and rice seedlings, indicating that consumption of edible plants exposed to microcystins via irrigation route may have health risks. Significantly different levels of recovered microcystins between exposed rice and rape seedlings suggested that there might be different tolerant mechanisms toward microcystins.

Thallium in French agrosystems-II. Concentration of thallium in field-grown rape and some other plant species.

The aim of this study was to assess thallium (Tl) uptake into the aerial parts of selected crop species grown on French soils with high Tl content of pedogeochemical origin (0.3-40 mg Tl kg(-1) on a dry wt (DW) basis). Husked wheat and maize grains contained less than 4 microg Tl kg(-1) DW, but rape shoots accumulated Tl with a shoot-soil partition coefficient (PC) > 1, and rape seeds had PC > 3. Tl content of rape seed reached 33 mg Tl kg(-1) DW and higher concentrations in soil corresponded to increased concentrations in rape seeds. It is argued that parent material of the soil and pedogenesis have a considerable effect on Tl accumulation in rape seeds. These results show enhanced phytoavailability of Tl of pedogeochemical origin and prompt questions on the potential for food chain contamination by Tl in rape cattle cakes.

Evaluation of the allergic/irritant potential of air pollutants: detection of proteins modified by volatile organic compounds from oilseed rape (Brassica napus ssp. oleifera) using electrospray ionization-mass spectrometry.

BACKGROUND: Upward trends in allergy and asthma rates have been reported in most western societies, including the UK, where around 15-20% of the population now suffer from allergy or asthma. Scientific proof of the causes of these increases relies on accurate assessment of exposure and standardized diagnostic tests, such as for specific IgE in blood serum and skin testing. For many air pollutants it has proven difficult to assess an individual's exposure outside an occupational environment and reliable test development is hampered by not knowing whether an allergic or irritant mechanism is involved. These problems are particularly evident in the controversial issue of whether airborne releases from oilseed rape can cause health effects. OBJECTIVE: To develop a method for evaluating the allergic/irritant potential of air pollutants and to assess whether the volatile organic compounds emitted by oilseed rape have this potential. METHODS: Proteins were exposed in vitro to volatile organic compounds emitted by oilseed rape. Electrospray ionization-mass spectrometry was used to detect any resultant protein modifications. RESULTS: Dimethyl disulphide, thiocyanic acid methyl ester and 2-methyl-propanenitrile were able to modify human proteins. In addition, two isothiocyanates which can be emitted by damaged oilseed rape also have this ability. The major products emitted by undamaged oilseed rape, terpenes, a sesquiterpene and a terpene alcohol did not have this property, but the possible role of their oxidized products is discussed. CONCLUSION: Some of the volatile organic compounds emitted by oilseed rape have the potential to be allergens/irritants. Standardized modified proteins produced by this method should prove useful for biomonitoring human exposure in molecular epidemiological studies as well as in diagnostic tests. This method should find further application in investigations into the possible health effects of other environmental pollutants.

The effect of dietary rape-seed oil on cholesterol-ester metabolism and cholesterol-ester-hydrolase activity in the rat adrenal.

The effects of stock diet and stock diet supplemented by olive oil and rape seed on rat adrenal cholesterol ester metabolism have been studied. Rats fed rape seed oil failed to gain weight at the same rate as rats fed olive oil. A prominent feature of the rats fed rape seed oil was an accumulation of high concentrations of cholesterol erucate in the adrenal lipid droplets. When these rats were subjected to an ether stress no percentage decrease in the amount of cholesterol erucate was observed. Adrenal cholesterol ester hydrolase activity was higher in rats fed the olive oil and rape seed oil diets than rats fed the stock diet. In rats fed stock or olive oil diets, a ten-minute ether anaesthesia stress resulted in a two-fold increase in activity of adrenal cholesterol ester hydrolase. Cofactor addition of ATP, cyclic AMP and MgCl-2 in vitro resulted in a stimulation of cholesterol ester hydrolase to a similar activity in both quiescent and ether-stressed rats. By contrast rats fed the rape seed oil diet gave no significant stimulation of cholesterol ester hydrolase activity when given an ether stress or when cofactors were added in vitro. Cholesterol erucate was hydrolysed at only 25% to 30% of the rate of cholesterol oleate in vitro in all groups of animals. Oleic acid added in vitro gave an inhibition of cholesterol ester hydrolase activity in rats fed stock diet while erucic acid activated the enzyme. The accumulation of cholesterol erucate in the adrenal when rats are fed rape seed oil could be due to the reduced ability of cholesterol ester hydrolase to hydrolyse this ester.

Does DNA methylation pattern mark generative development in winter rape?

In this paper we report on changes in DNA methylation pattern in rape apices and leaves during transition from vegetative to reproductive stage due to grafting and/or vernalization. Grafted plants of winter rape (Brassica napus L., var. "Górczański") (stock from vernalized, scion from non-vernalized plants) were used together with vernalized non-grafted plants. In addition, methylation status was determined also in spring rape (var. "Młochowski") grown under normal and low temperature. The methylation-sensitive amplification polymorphism (MSAP) method with EcoRI/MspI and EcoRII/HpaII restriction enzymes was employed. The majority (ca. 68%) of analyzed loci (566 in winter and 551 in spring rape) were monomorphic, i.e. did not undergo methylation. Both cultivars showed a similar degree of methylation. 188 loci in winter and 176 in spring cultivars expressed changes in the methylation pattern. All differentially amplified fragments resulted from either full methylation of an internal cytosine or from hemi-methylation of an external cytosine. A pair-wise comparison showed that a similar number of loci underwent development-related methylation changes in apices of the winter and spring rape. The majority (80%) of changes were demethylation events in generative (vernalized) apices of the winter cultivar. However, an increased number of demethylated loci was detected in vernalized apices in comparison with generative, non-vernalized ones. In apices of vegetative and generative grafted plants the same number of demethylation events was observed. Overall, 10 MSAP loci were detected that expressed methylation changes in vernalized apices only; among them 7 loci underwent demethylation after vernalization and remained methylated in both vegetative and generative non-vernalized stage. Only 1 locus was demethylated in generative non-vernalized apices. Thus, most of demethylation events can be ascribed to vernalization and not to the generative stage. In leaves of winter rape methylation and demethylation events occurred with similar frequency, while in the spring cultivar more demethylation events were detected. The results show that during vernalization and transition to the generative stage different sets of genes are activated.

Effect of hay substitution on intake and digestibility of forage rape (brassica napus) fed to lambs.

Intake and digestibility trials were conducted with sheep to evaluate the effect of adding various levels of a typical fibrous grass forage (neutral detergent fiber, NDF = 68%) to a high quality, low fiber (NDF = 22%) brassica forage. Four forage rape:orchardgrass hay diets (0, 40, 70, 100% rape content on a dry matter basis) were fed to groups of six Polled-Dorset crossbred growing wether lambs (39.6 kg) individually housed in metabolism crates. After a 7-d ad libitum intake period, a 7-d digestibility trial was conducted at 90% of the observed ad libitum intake level. Digestible dry matter intake (DDMI) per unit metabolic body weight increased as rape in the diet was increased from 0 to 70%, with increases in both dry matter intake and dry matter digestibility (DMD). However, DDMI was similar for lambs fed the 70 and 100% rape diets, with DMI decreasing to the same relative extent as DMD increased. Digestibility of the cell wall fraction of the two intermediate diets (40% rape and 70% rape) was lower than predicted from component forage digestibilities. This observation suggests the existence of an associative effect similar to that often reported when forage and concentrates are fed in various ratios. Forage brassicas appear to be utilized in the ruminant in a manner more typically resembling a concentrate than a forage.

Characteristics of Cd uptake and accumulation in two Cd accumulator oilseed rape species.

Two pot experiments were conducted under greenhouse conditions to investigate the characteristics of Cd uptake and accumulation by two Cd accumulator oilseed rape varieties and one Indian mustard grown on a loamy soil that had been artificially contaminated by different amounts of CdSO4 (0, 20, 40, 60, 80, 100 mg/kg soil). The relationship between shoot Cd uptake of the two oilseed rape cultivars and the soil Cd concentrations could be simulated via quadratic equations. The curve showed that maximum shoot Cd uptake of Indian mustard was 314.7 microg/pot at soil Cd concentration of 87.8 mg/kg, while maximum uptake of the variety Xikou Huazi was 543.3 microg/pot at soil Cd concentration of 69.1 mg/kg and that of the variety Zhongyou Za-1hao was 576.7 microg/pot at soil Cd concentration of 84.0 mg/kg, suggesting that shoot Cd uptake ability of the two Cd accumulator oilseed rapes was significantly higher than that of the Indian mustard. Xikou Huazi had higher phytoremediation potential for Cd contaminated soil. Shoot Cd accumulation ability of the two Cd accumulator oilseed rapes was correspond and Cd was easier translocated to the shoot than hyperaccumulator Indian mustard as comparation plant. Shoot Cd distribution pattern showed consistent and significant reduction from older leaves to younger ones of two oilseed rapes and Indian mustard. Cd uptake by oilseed rapes in growth prophase was higher than that of growth anaphase.

Factors associated with women's risk of rape in the military environment.

BACKGROUND: Health hazards specific to women workers have not been adequately documented. This study assessed military environmental factors associated with rape occurring during military service, while controlling for pre-military trauma experiences. METHODS: A national cross-sectional survey of 558 women veterans serving in Vietnam or in subsequent eras was obtained through structured telephone interviews. RESULTS: Rape was reported by 30% (n = 151) of participants, with consistent rates found across eras [corrected]. Military environmental factors were associated with increased likelihood of rape, including: sexual harassment allowed by officers (P < 0.0001), unwanted sexual advances on-duty (P < 0.0001) and in sleeping quarters (P < 0.0001). CONCLUSION: Violence towards military women has identifiable risk factors. Work and living environments where unwanted sexual behaviors occurred were associated with increased odds of rape. Officer leadership played an important role in the military environment and safety of women. Assailant alcohol and/or drug abuse at time of rape was notable. Interventions and policies based on modifiable environmental risk factors are needed to increase protection for women in the workplace.

Differentiating sex offences: a behaviorally based thematic classification of stranger rapes.

It is hypothesized that stranger rape victim statements will reveal a scale of violation experienced by the victim, ranging from personal violation, through to physical violation, and finally, at the most extreme level, sexual violation. It is also hypothesized that offences can be differentiated in terms of one of four themes: hostile, controlling, stealing, or involving. To test these hypotheses, crime scene data from 112 rapes were analyzed by the multi-dimensional scaling procedure Smallest Space Analysis. The results provide empirical support for a composite model of rape consisting of four behavioral themes as different expressions of various intensities of violation. The results also suggest that stranger rapes may be less about power and control than about hostility and pseudo-intimacy. The proposed model has implications for the classification of rape, the investigation of sexual crimes, and the treatment of victims.
