A method of determining the change in the fi ltration properties of oil-bearing crops in the process of their pressing by repeated dynamic loading is proposed. The use of this method is demonstrated by the example of rape-oil extrusion. It was established that the change in the mass concentration of the oil in a rape mix from 0.45 to 0.23 leads to a decrease in the permeability of the mix by 101.5-102 times depending on the pressure applied to it. It is shown that the dependence of the permeability of this mix on the pressure applied to it is nonmonotone in character.

Rape is prevalent at colleges. Although research suggests commonalities across many college women's rape experiences (e.g., perpetrators using multiple coercive strategies), vignettes used to assess rape perceptions often reflect false beliefs. Two studies varying a perpetrator's coercive tactics examine rape perceptions using vignettes reflecting rape myths, rape scripts, or many college women's common rape experiences. Participants perceive a woman who was raped more positively in vignettes reflecting common rape experiences versus those reflecting rape myths or scripts. Theoretical, educational, and research implications are discussed. © The Author(s) 2015.

Wild bees are essential pollinators whose survival partly depends on the capacity of their environment to offer a sufficient amount of nectar and pollen. Semi-natural habitats and mass-flowering crops such as oilseed rape provide abundant floristic resources for bees. The aim of this study was to evaluate the influences of the spatial distribution of semi-natural habitats and oilseed rape fields on the abundance and the mean body size of a solitary bee in grasslands. We focused on a generalist mining bee, Andrena cineraria, that forages and reproduces during oilseed rape flowering. In 21 permanent grasslands of Eastern France, we captured 1 287 individuals (1 205 males and 82 females) and measured the body size of male individuals. The flower density in grasslands was quantified during bee captures (2016) and the landscape surrounding grasslands was characterized during two consecutive years (2015 and 2016). The influence of oilseed rape was tested through its distribution in the landscape during both the current year of bee sampling and the previous year. Bee abundance was positively influenced by the flower density in grasslands and by the area covered by oilseed rape around grasslands in the previous year. The mean body size of A. cineraria was explained by the interaction between flower density in the grassland and the distance to the nearest oilseed rape field in the current year: the flower density positively influenced the mean body size only in grasslands distant from oilseed rape. A. cineraria abundance and body size distribution were not affected by the area of semi-natural habitats in the landscape. The spatial distribution of oilseed rape fields (during both the current and the previous year) as well as the local density of grassland flowers drive both bee abundance and the mean value of an intraspecific trait (body size) in permanent grasslands. Space-time variations of bee abundance and mean body size in grasslands may have important ecological

Remote Diagnosis of Nitrogen Status in Winter Oilseed Rape

2016-12-01

Winter oilseed rape is one of the most important oilseed crops in the world. Compared with cereal crops, it requires high amount of nitrogen (N) supplies, but it is also characterized by low N use efficiency. The N nutrition index (NNI), defined as the ratio of the actual plant N concentration (PNC) to the critical PNC at a given biomass level, has been widely used to diagnose plant N status and to aid optimizing N fertilization. But traditional techniques to determine NNI in the lab are time-consuming and expensive. Remote sensing provides a promising approach for large-scale and rapid monitoring and diagnosis of crop N status. In this study, we conducted the experiment in the winter oilseed rape field with eight fertilization treatments in the growing season of 2014 and 2015. PNC, dry mass, and canopy spectra were measured during the different growth stages of winter oilseed rape. The N dilution curve was developed with measurements, and NNI was computed and analyzed for different treatments and different growth stage. For the same treatment, NNI decreased as more leaves were developing. Two methods were applied to remotely estimating NNI for winter oilseed rape: (1) NNI was estimated directly with vegetation indices (VIs) derived from canopy spectra; (2) the actual PNC and the critical PNC at the given biomass level were estimated separately with different types of VIs, and NNI was then computed with the two parts of the estimations. We found that VIs based solely on bands in the visible region provided the most accurate estimates of PNC. Estimating NNI directly with VIs had better performance than estimating the actual PNC and the critical PNC separately.

This manuscript presents research results examining phosphorus (P) management in a soil–plant system for three variables: i) internal resources of soil available phosphorus, ii) cropping sequence, and iii) external input of phosphorus (manure, fertilizers). The research was conducted in long-term cropping sequences with oilseed rape (10 rotations) and maize (six rotations) over three consecutive growing seasons (2004/2005, 2005/2006, and 2006/2007) in a production farm on soils originated from Albic Luvisols in Poland. The soil available phosphorus pool, measured as calcium chloride extractable P (CCE-P), constituted 28% to 67% of the total phosphorus input (PTI) to the soil–plant system in the spring. Oilseed rape and maize dominant cropping sequences showed a significant potential to utilize the CCE-P pool within the soil profile. Cropping sequences containing oilseed rape significantly affected the CCE-P pool, and in turn contributed to the P(TI). The P(TI) uptake use efficiency was 50% on average. Therefore, the CCE-P pool should be taken into account as an important component of a sound and reliable phosphorus balance. The instability of the yield prediction, based on the P(TI), was mainly due to an imbalanced management of both farmyard manure and phosphorus fertilizer. Oilseed rape plants provide a significant positive impact on the CCE-P pool after harvest, improving the productive stability of the entire cropping sequence. This phenomenon was documented by the P(TI) increase during wheat cultivation following oilseed rape. The Unit Phosphorus Uptake index also showed a higher stability in oilseed rape cropping systems compared to rotations based on maize. Cropping sequences are a primary factor impacting phosphorus management. Judicious implementation of crop rotations can improve soil P resources, efficiency of crop P use, and crop yield and yield stability. Use of cropping sequences can reduce the need for external P sources such as farmyard manure

Many crop pests rely on resources out of crop fields; understanding how they colonize the fields is an important factor to develop integrated pest management. In particular, the time of crop colonization and damage severity might be determined by pest movements between fields and non-crop areas. Notably, the pollen beetle, Brassicogethes aeneus, previously named Meligethes aeneus, one of the most important pests of winter oilseed rape, overwinters in woodlands. As a result, its abundance increases in oilseed rape fields near wooded areas. Here, we assessed the spatio-temporal patterns of the dispersal from woodlands to oilseed rape fields in diversified landscapes of a same region. We observed on four dates the abundance of pollen beetles in 24 fields spread in the Eure department, France. We modeled the abundance as a result of the dispersal from the neighboring woodlands. We compared the modalities of dispersal corresponding to different hypotheses on the dispersal origin, kernel shape and sources of variability. Within oilseed rape the distance to the edges of woodlands is not the main determinant of pollen beetle abundance. On the contrary, the variability of the abundance between fields is largely explained by the dispersal from neighboring woodlands but there is considerable variability between dates, sites and, to a lesser extent, between fields. The two dispersal kernels received similar support from the data and lead to similar conclusions. The mean dispersal distance is 1.2 km but seems to increase from a few hundred meters the first week to more than two kilometers the fourth, allowing the pollen beetles to reach more distant OSR fields. These results suggest that early varieties away from woodlands and late varieties close to the woodlands may limit attacks at the time when oilseed rape is the most sensitive. PMID:28841712

Sclerotinia sclerotiorum causes serious yield losses on many crops throughout the world. A multicomponent treatment that consisted of the residual rice straw remaining after rice harvest and Trichoderma sp. Tri-1 (Tri-1) formulated with the oilseed rape seedcake fertilizer was used in field soil infested with S. sclerotiorum. This treatment resulted in oilseed rape seed yield that was significantly greater than the nontreated control or when the fungicide carbendizem was used in the presence of this pathogen in field trials. Yield data suggested that the rice straw, oilseed rape seedcake, and Tri-1 components of this treatment all contributed incrementally. Similar treatment results were obtained regarding reduction in disease incidence. Slight improvements in yield and disease incidence were detected when this multicomponent treatment was combined with a fungicide spray. Inhibition of sclerotial germination by this multicomponent treatment trended greater than the nontreated control at 90, 120, and 150 days in field studies but was not significantly different from this control. This multicomponent treatment resulted in increased yield relative to the nontreated control in the absence of pathogen in a greenhouse pot study, while the straw alone and the straw plus oilseed rape seedcake treatments did not; suggesting that Tri-1 was capable of promoting growth. Experiments reported here indicate that a treatment containing components of a rice-oilseed rape production system augmented with Tri-1 can control S. sclerotiorum on oilseed rape, be used in integrated strategies containing fungicide sprays for control of this pathogen, and promote plant growth.

The presence of glyphosate-resistant oilseed rape populations in Argentina was detected and characterized. The resistant plants were found as weeds in RR soybeans and other fields. The immunological and molecular analysis showed that the accessions presented the GT73 transgenic event. The origin of this event was uncertain, as the cultivation of transgenic oilseed rape cultivars is prohibited in Argentina. This finding might suggest that glyphosate resistance could come from unauthorized transgenic oilseed rape crops cultivated in the country or as seed contaminants in imported oilseed rape cultivars or other seed imports. Experimentation showed that there are alternative herbicides for controlling resistant Brassica napus populations in various situations and crops. AHAS-inhibiting herbicides (imazethapyr, chlorimuron and diclosulam), glufosinate, 2,4-D, fluroxypyr and saflufenacil proved to be very effective in controlling these plants. Herbicides evaluated in this research were employed by farmers in one of the fields invaded with this biotype and monitoring of this field showed no evidence of its presence in the following years.

Predicting Rape Victim Empathy Based on Rape Victimization and Acknowledgment Labeling.

Two studies examined rape victim empathy based on personal rape victimization and acknowledgment labeling. Female undergraduates (Study 1, n = 267; Study 2, n = 381) from a Northeast U.S. midsize public university completed the Rape-Victim Empathy Scale and Sexual Experiences Survey. As predicted, both studies found that acknowledged "rape" victims reported greater empathy than unacknowledged victims and nonvictims. Unexpectedly, these latter two groups did not differ. Study 1 also found that acknowledged "rape" victims reported greater empathy than victims who acknowledged being "sexually victimized." Findings suggest that being raped and acknowledging "rape" together may facilitate rape victim empathy. © The Author(s) 2015.

Crop production for vegetable oil in the northern latitudes utilises oilseed rape (Brassica napus subsp. oleifera) and turnip rape (B. rapa subsp. oleifera), having similar oil compositions. The oil consists mostly of triacylglycerols, which are synthesised during seed development. In this study, we characterised the oil composition and the expression levels of genes involved in triacylglycerol biosynthesis in the developing seeds in optimal, low temperature (15 °C) and short day (12-h day length) conditions. Gene expression levels of several genes were altered during seed development. Low temperature and short day treatments increased the level of 9,12,15-octadecatrienoic acid (18:3n-3) in turnip rape and short day treatment decreased the total oil content in both species. This study gives a novel view on seed oil biosynthesis under different growth conditions, bringing together gene expression levels of the triacylglycerol biosynthesis pathway and oil composition over a time series in two related oilseed species.

Rape myth acceptance and rape acknowledgment: The mediating role of sexual refusal assertiveness.

Unacknowledged rape, defined as when an individual experiences an event that meets a legal or empirical definition of rape but the individual does not label it as such, is prevalent. Research examining predictors of rape acknowledgment is needed. Sexual assertiveness may be an important variable to consider, as an individual's typical behavior during sexual situations may influence rape acknowledgment. To assess the indirect effect of rape myth acceptance on rape acknowledgment through sexual refusal assertiveness, an online survey of 181 female rape survivors was conducted. The indirect effects of two types of rape myths (He didn't mean to and Rape is a deviant event) were significant and positive. Specifically, acceptance of these two rape myths was negatively related to sexual refusal assertiveness, which was negatively associated with likelihood of rape acknowledgment. The results of this study indicate that sexual refusal assertiveness is associated with lower likelihood of rape acknowledgment among rape survivors. As a result, it appears that, under certain circumstances, women high in rape myth acceptance may be more likely to acknowledge rape when it results in decreased sexual refusal assertiveness.

Oilseed rape and seasonal symptoms: epidemiological and environmental studies.

Soutar, A.; Harker, C.; Seaton, A.; Brooke, M.; Marr, I.

1994-01-01

BACKGROUND--There is widespread concern that the cultivation of oilseed rape leads to seasonal epidemics of respiratory symptoms in populations living in the neighbourhood, and it has been suggested that the plant is a potent allergen. A study was therefore undertaken to determine the prevalence of seasonal symptoms in rural populations close to and far from areas of oilseed rape cultivation, and to measure the levels of allergen and other potentially harmful substances released by the crop. METHODS--Random samples of 1000 adults from the general practice populations of two villages surrounded by oilseed rape fields, and 1000 adults from one village far from such cultivation, were taken. The subjects completed a previously validated questionnaire on respiratory and other symptoms, including questions on symptom seasonality, occupation, and smoking habits. Pollen and fungal spore counts were made around fields of oilseed rape and in the villages. The chemicals released by oilseed rape were measured in the field. RESULTS--Overall, 86.8% of the subjects completed the questionnaires and the populations of the two samples were generally comparable. Spring and summer exacerbations of symptoms occurred equally in the two areas in approximately 25% of the population. There were small but significant excesses of cough, wheeze, and headaches in spring in the oilseed rape area (2.3% v 1.1%, 6.8% v 4.6%, and 4.8% v 2.8%, respectively), and cough, wheeze, and itchy skin were more prevalent in smokers. Counts of oilseed rape pollen were generally low except adjacent to fields, and counts of fungal spores were mostly higher in the rape than the non-rape areas. Oilseed rape was shown to give off terpenes and these were detected close to fields. CONCLUSIONS--While it is likely that a proportion of the spring symptoms occurring in people living in close proximity to oilseed rape is caused by the plant, the excess of such symptoms is small. This, together with the low levels of

Law enforcement officers' perception of rape and rape victims: a multimethod study.

In a study to assess law enforcement officers' perceptions of rape and rape victims, researchers asked 149 law enforcement officers to respond to surveys which included a definition of rape measure, an unfounded rape claims measure, and the Rape Myth Acceptance Scale-Revised (RMA-R) measure. Although most officers scored low on the RMA-R--indicating that they did not adhere to myths about rape--most officers also responded with incomplete definitions of rape and inaccurate estimates of the number of false rape claims. Multivariate analyses indicated that officers' open-ended responses did not predict their scores on the RMA-R scale. It is argued that the RMA-R alone does not accurately measure officers' understanding of rape. Officers need ongoing training on the legal elements of the crime, the necessity of sensitivity with victims, and research-based statistics on the prevalence of rape.

Application of a rotation system to oilseed rape and rice fields in Cd-contaminated agricultural land to ensure food safety.

This field experiment analyzed the phytoremediation effects of oilseed rape in moderately cadmium (Cd)-contaminated farmland and the food safety of successive rice in an oilseed rape-rice rotation system. Two oilseed rape cultivars accumulated Cd at different rates. The rapeseed cultivar Zhucang Huazi exhibited high Cd accumulation rates, higher than the legal limit for human consumption (0.2mgkg(-1)); Cd concentrations in the cultivar Chuanyou II-93 were all below the maximum allowed level. Planting oilseed rape increased the uptake of Cd by the successive rice crop compared with a previous fallow treatment. Most Cd concentrations of brown rice were below the maximum allowed level. The phytoextraction efficiency was lower in the moderately Cd-contaminated soil in field experiments. The results suggest screening rice cultivars with lower Cd accumulation can assure the food safety; the mobilization of heavy metals by roots of different plant species should be considered during crop rotation to assure food safety.

The effects of eight summer rotation crops on nematode densities and yields of subsequent spring vegetable crops were determined in field studies conducted in north Florida from 1991 to 1993. The crop sequence was as follows: (i) rotation crops during summer 1991; (ii) cover crop of rye (Secale cereale) during winter 1991-92; (iii) 'Lemondrop L' squash (Cucurbita pepo) during spring 1992; (iv) rotation crops during summer 1992; (v) rye during winter 1992-93; (vi) 'Classic' eggplant (Solanum melongena) during spring 1993. The eight summer crop rotation treatments were as follows: 'Hale' castor (Ricinus communis), velvetbean (Mucuna deeringiana), sesame (Sesamum indicum), American jointvetch (Aeschynomene americana), weed fallow, 'SX- 17' sorghum-sudangrass (Sorghum bicolor x S. sudanense), 'Kirby' soybean (Glycine max), and 'Clemson Spineless' okra (Hibiscus esculentus) as a control. Rotations with castor, velvetbean, American jointvetch, and sorghum-sudangrass were most effective in maintaining the lowest population densities of Meloidogyne spp. (a mixture of M. incognita race 1 and M. arenaria race 1), but Paratrichodorus minor built up in the sorghum-sudangrass rotation. Yield of squash was lower (P crops evaluated here may be useful for managing nematodes in the field and for improving yields of subsequent vegetable crops.

An overview discusses feminist analyses of oppression, attitudes toward rape victims, and previously studied predictors of individuals' attitudes toward rape victims. To better understand such attitudes, this meta-analysis examines the moderating influences of various rape victim, perpetrator, and crime characteristics' rape myth consistency on gender differences in individuals' perceptions of rape victims (i.e., victim responsibility and blame attributions and rape minimizing attitudes). Consistent with feminist theoretical predictions, results indicated that, overall, men perceived rape victims more negatively than women did. However, this sex difference was moderated by the rape myth consistency within the rape vignettes. Implications for research are discussed. © The Author(s) 2015.

Background While rape is a very serious crime and public health problem, no spatial mapping has been attempted for rape on the national scale. This paper addresses the three research questions: (1) Are reported rape cases randomly distributed across the USA, after being adjusted for population density and age, or are there geographical clusters of reported rape cases? (2) Are the geographical clusters of reported rapes still present after adjusting for differences in poverty levels? (3) Are there geographical clusters where the proportion of reported rape cases that lead to an arrest is exceptionally low or exceptionally high? Methods We studied the geographical variation of reported rape events (2003-2012) and rape arrests (2000-2012) in the 48 contiguous states of the USA. The disease Surveillance software SaTScan™ with its spatial scan statistic is used to evaluate the spatial variation in rapes. The spatial scan statistic has been widely used as a geographical surveillance tool for diseases, and we used it to identify geographical areas with clusters of reported rape and clusters of arrest rates for rape. Results The spatial scan statistic was used to identify geographical areas with exceptionally high rates of reported rape. The analyses were adjusted for age, and in secondary analyses, for both age and poverty level. We also identified geographical areas with either a low or a high proportion of reported rapes leading to an arrest. Conclusions We have identified geographical areas with exceptionally high (low) rates of reported rape. The geographical problem areas identified are prime candidates for more intensive preventive counseling and criminal prosecution efforts by public health, social service, and law enforcement agencies Geographical clusters of high rates of reported rape are prime areas in need of expanded implementation of preventive measures, such as changing attitudes in our society toward rape crimes, in addition to having the criminal

Knowledge of variability in climatic variables changes and its impact on crop yields is important for farmers and policy makers, especially in southwestern China where rainfed agriculture is dominant. In the current study, six climatic parameters (mean temperature, rainfall, relative humidity, sunshine hours, temperature difference, and rainy days) and aggregated yields of three main crops (rice: Oryza sativa L., oilseed rape: Brassica napus L., and tobacco: Nicotiana tabacum L.) during 1985-2010 were collected and analyzed for Chongqing—a large agricultural municipality of China. Climatic variables changes were detected by Mann-Kendall test. Increased mean temperature and temperature difference and decreased relative humidity were found in annual and oilseed rape growth time series ( P < 0.05). Increased sunshine hours were observed during the oilseed rape growth period ( P < 0.05). Rainy days decreased slightly in annual and oilseed rape growth time series ( P < 0.10). Correlation analysis showed that yields of all three crops could benefit from changes in climatic variables in this region. Yield of rice increased with rainfall ( P < 0.10). Yield of oilseed rape increased with mean temperature and temperature difference but decreased with relative humidity ( P < 0.01). Tobacco yield increased with mean temperature ( P < 0.05). Path analysis provided additional information about the importance and contribution paths of climatic variables to crop yields. Temperature difference and sunshine hours had higher direct and indirect effects via other climatic variables on yields of rice and tobacco. Mean temperature, relative humidity, rainy days, and temperature difference had higher direct and indirect effects via others on yield of oilseed rape.

Attitudes toward rape and victims of rape: a test of the feminist theory in Ghana.

PubMed

Boakye, Kofi E

2009-10-01

This study explores the usefulness of the feminist theory in explaining attitudes toward rape and victims of rape in Ghana. The feminist theory of rape posits, inter alia, that patriarchy and gender inequality are major factors in the aetiology of rape and attitudes toward rape and that underlying patriarchy and gender inequality are gender stereotypes and false beliefs (myths) about rape, rapists, and victims of rape. Thus, the theory suggests a relationship between rape myths and less favorable attitudes toward rape and victims of rape. Results from a survey conducted in Ghana show some support for the feminist theory of rape: There is evidence of rape myth acceptance in Ghana; gender is significant in predicting levels of rape myth acceptance; and finally, education or profession and age, but not religion, are associated with levels of rape myth acceptance in a predictable way.

Precursors to rape: pressuring behaviors and rape proclivity.

We developed measures assessing personal and normative attitudes toward two types of behaviors that are symptomatic of rape culture. We conceptualize sexual violence as existing on a continuum and argue that two types of behaviors may be potential antecedents to (and consequences of) sexual violence: attempts to pressure, which mimic the power dynamics of rape in a less aggressive fashion, and benevolent dating behaviors, which are accepted dating scripts in which men initiate action. We examined individuals' acceptance of these behaviors in relation to their attitudes toward rape victims and among men to rape proclivity. This initial work suggests that these constructs and measures may be useful to investigate in future research.

A survey was conducted in 230 cases of rape and rape attempts heard in the Judicial District of Montreal between January 1975 and May 1978. Data were compiled from the 30 assaults including two or more assaillants. Results show that in cases of rape committed by two men the aggressors are older than gang rapists, meet the victim mainly in her flat or in a bar, and rape her in her own home, in a car or a hotel. In these cases, voyeurism seems to be an important factor since, most of the time, rape is committed by only one of the two aggressors. On the other hand, gang rapists are younger, meet the victim in public places, on the street or when she is hitch-hiking and attack her in one of the aggressors' house, in public places or on the street. Exhibitionism seems more present in this group of rapists. For both groups the victims are mainly single, younger than the aggressors and have diverse occupations. Finally, regarding the legal outcome half of the subjects were liberated or acquitted in both groups. Rape committed by two men had never been studied or compared with gang rape up until now. Results of this survey show dynamic and demographic differences between these two groups of sexual delinquents.

This study developed an approach for remote estimation of Vegetation Fraction (VF) and yield in oilseed rape, which is a crop species with conspicuous flowers during reproduction. Canopy reflectance in green, red, red edge and NIR bands was obtained by a camera system mounted on an unmanned aerial vehicle (UAV) when oilseed rape was in the vegetative growth and flowering stage. The relationship of several widely-used Vegetation Indices (VI) vs. VF was tested and found to be different in different phenology stages. At the same VF when oilseed rape was flowering, canopy reflectance increased in all bands, and the tested VI decreased. Therefore, two algorithms to estimate VF were calibrated respectively, one for samples during vegetative growth and the other for samples during flowering stage. During the flowering season, we also explored the potential of using canopy reflectance or VIs to estimate Flower Fraction (FF) in oilseed rape. Based on FF estimates, rape yield can be estimated using canopy reflectance data. Our model was validated in oilseed rape planted under different nitrogen fertilization applications and in different phenology stages. The results showed that it was able to predict VF and FF accurately in oilseed rape with estimation error below 6% and predict yield with estimation error below 20%.

Brassica cover crops are new to the mid-Atlantic region, and limited information is available on their N uptake capabilities for effective N conservation. Forage radish (Raphanus sativus L. cv. Daikon), oilseed radish (Raphanus sativus L. cv. Adagio), and rape (Brassica napus L. cv. Dwarf Essex) were compared with rye (Secale cereale L. cv. Wheeler), a popular cover crop in the region, with regard to N uptake ability and potential to decrease N leaching at two sites in Maryland. Plants were harvested in fall and spring for dry matter and N analysis. Soil samples from 0 cm to 105 to 180 cm depth were obtained in fall and spring for NH(4)-N and NO(3)-N analyses. Ceramic cup tension lysimeters were installed at depths of 75 to 120 cm to monitor NO(3)-N in soil pore water. Averaged across 3 site-years, forage radish and rape shoots had greater dry matter production and captured more N in fall than rye shoots. Compared with a weedy fallow control, rape and rye caused similar decreases in soil NO(3)-N in fall and spring throughout the sampled profile. Cover crops had no effect on soil NH(4)-N. During the spring on coarse textured soil, pore water NO(3)-N concentrations in freeze-killed Brassica (radish) plots were greater than in control and overwintering Brassica (rape) and rye plots. On fine textured soil, all cover crops provided a similar decrease in pore water NO(3)-N concentration compared with control. On coarse textured soils, freeze-killed Brassica cover crops should be followed by an early-planted spring main crop.

Rape (Brassica napus L.) is a major global oilseed crop characterized by its high potential as an alimentary oil and in biodiesel production. The two most popular pod sealants (PS) used to reduce rape pod shattering are products in the pinolene range (di-1-p-menthene) and latex polymer products. Reports on the effective preservation of seed yield by these products are fairly contradictory. With this in mind, an experimental PS (PS4) that contained the active agents acrylic and trisiloxane was developed. Comparative experimental trials of the developed PS4 and three other PS (PS1, PS2 and PS3) containing active agents that are generally used for sealant production were conducted. The studies showed that the static and dynamic surface tension of PS4 was the lowest at the same concentration (2.0 g kg -1 ), consequently demonstrating the lowest spray drift. The chemical substances from PS had not penetrated the rape seeds in any of the PSs. The results indicate that treatment with PS4 exerts a beneficial effect in reducing rape seed yield loss (68-104 kg ha -1 in 2014 and 194-305 kg ha -1 in 2015) compared to other investigated PS. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Wild turnip (Brassica rapa) is a common weed and a close relative to oilseed rape (Brassica napus). The Clearfield® production system is a highly adopted tool which provides an alternative solution for weed management, but its efficiency is threatened by gene transfer from crop to weed relatives. Crop-weed hybrids with herbicide resistance were found in the progeny of a B. rapa population gathered from a weedy stand on the borders of an oilseed rape (B. napus) imidazolinone (IMI)-resistant crop. Interspecific hybrids were confirmed by morphological traits in the greenhouse and experimental field, survival after imazethapyr applications, DNA content through flow cytometry, and pollen viability. The transference of herbicide resistance was demonstrated even in a particular situation of pollen competition between both an herbicide-resistant crop and a non-resistant crop. However, IMI resistance was not found in further generations collected at the same location. These results verify gene transmission from oilseed rape to B. rapa in the main crop area in Argentina where resistant and susceptible varieties are found and seed loss and crop volunteers are common. Hybridization, introgression, and herbicide selection would be associated with the loss of effectiveness of IMI technology.

Tropospheric ozone is an important air pollutant with known detrimental effects for several crops. Ozone effects on seed yield, oil percentage, oil yield and 1000 seed weight were examined for spring oilseed rape ( Brassica napus cv. Ability). For broccoli ( Brassica oleracea L. cv. Italica cv. Monaco) the effects on fresh marketable weight and total dry weight were studied. Current ozone levels were compared with an increase of 20 and 40 ppb during 8 h per day, over the entire growing season. Oilseed rape seed yield was negatively correlated with ozone dose indices calculated from emergence until harvest. This resulted in an R2 of 0.24 and 0.26 ( p < 0.001) for the accumulated hourly O 3 exposure over a threshold of 40 ppb (AOT40) and the phytotoxic ozone dose above a threshold of 6 nmol m -2 s -1 (POD 6) respectively. Estimated critical levels, above which 5% yield reduction is expected, were 3.7 ppm h and 4.4 mmol m -2 respectively. Our results also confirm that a threshold value of 6 nmol s -1 m -2 projected leaf area, as recommended for agricultural crops (UNECE, Mills, 2004), can indeed be applied for spring oilseed rape. The reduction of oilseed rape yield showed the highest correlation with the ozone uptake during the vegetative growth stage: when only the first 47 days after emergence were used to calculate POD 6, R2 values increased up to 0.476 or even 0.545 when the first 23 days were excluded. The highest ozone treatments, corresponding to the future ambient level by 2100 (IPCC, Meehl et al., 2007), led to a reduction of approximately 30% in oilseed rape seed yield in comparison to the current ozone concentrations. Oil percentage was also significantly reduced in response to ozone ( p < 0.001). As a consequence oil yield was even more severely affected by elevated ozone exposure compared to seed yield: critical levels for oil yield dropped to 3.2 ppm h and 3.9 mmol m -2. For broccoli the applied ozone doses had no effect on yield.

Rape and homosexuality.

PubMed

Cohen-Addad, G

1990-01-01

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.

Repeated monitoring for escaped transgenic crop plants is sometimes necessary, especially in cases when the crop has not been approved for release into the environment. Transgenic oilseed rape (Brassica napus) was detected along roadsides in central Japan in a previous study. The goal of the current study was to monitor the distribution of transgenic oilseed rape and occurrence of hybridization of transgenic B. napus with feral populations of its closely related species (B. rapa and B. juncea) in the west of Japan in 2005. The progenies of 50 B. napus, 82 B. rapa and 283 B. juncea maternal plants from 95 sampling sites in seven port areas were screened for herbicide-resistance. Transgenic herbicide-resistant seeds were detected from 12 B. napus maternal plants growing at seven sampling sites in two port areas. A portion of the progeny from two transgenic B. napus plants had both glyphosate-resistance and glufosinate-resistance transgenes. Therefore, two types of transgenic B. napus plants are likely to have outcrossed with each other, since the double-herbicide-resistant transgenic strain of oilseed rape has not been developed intentionally for commercial purposes. As found in the previous study, no transgenic seeds were detected from B. rapa or B. juncea, and more extensive sampling is needed to determine whether introgression into these wild species has occurred.

1994-12-01

Effects of winter cover crop management on nematode densities associated with a subsequent corn (Zea mays) crop were examined in five sites in north Florida. Two sites had received winter cover crops of lupine (Lupinus angustifolius), and one site each had rye (Secale cereale), hairy vetch (Vicia villosa), and crimson clover (Trifolium incarnatum). In each site, five different management regimes were compared: 1) conventional tillage after the cover crop was removed for forage; 2) conventional tillage with the cover crop retained as green manure; 3) no-till with the cover crop mowed and used as a mulch; 4) no-till with the cover crop removed as forage; and 5) fallow. Sites were sampled at corn planting and harvest for estimates of initial (Pi) and final (Pf) nematode population densities, respectively. Whether the cover crop was removed as forage or retained as green manure or mulch had no effect (P > 0.10) on population densities of any plant-parasitic nematode before or after corn at any site. Differences between conventional-till and no-till treatments were significant (P crop residues had little consistent effect on nematodes, and these practices should be considered based on agronomic benefits rather than for nematode management.

Rape myths are false beliefs about rape, rape victims, and rapists, often prejudicial and stereotypical. Guided by feminist theory and available empirical research, this study aimed to examine the influences of gender, religious affiliation, and religiosity on rape myth acceptance of U.S. emerging adults. A sample of 653 university students aged 18 to 30 years were recruited from a large public university in the southern United States to complete the research questionnaires. Results indicated that individuals who identified as Roman Catholic or Protestant endorsed higher levels of rape myth acceptance than their atheist or agnostic counterparts. Men were found more likely to ascribe to rape myths than their female counterparts. Religiosity was positively associated with rape myth acceptance, even after controlling the effect of conservative political ideology. No significant interaction was found between gender and religious affiliation or gender and religiosity. Limitations, future research directions, and implications of the findings are discussed from the perspective of feminist theory.

Performance of winter rape (Brassica napus) based fuel mixtures in diesel engines

Winter rape is well adapted to the Palouse region of Northern Idaho and Eastern Washington. Nearly all of the current US production is grown in this region. Yields of 2200 to 2700 kg/ha with 45 percent oil content are common. Even though present production only 2000 to 2500 ha per year, the long history of production and good yields of oil make winter rape the best potential fuel vegetable oil crop for the region. Winter rape oil is more viscous than sunflower oil (50 cSt at 40/sup 0/C for winter rape and 35 cSt at 40/sup 0/C for sunflower oil)more » and about 17 times more viscous than diesel. The viscosity of the pure oil has been found too high for operation in typical diesel injector systems. Mixtures and/or additives are essential if the oil is to be a satisfactory fuel. Conversely, the fatty acid composition of witer rape oils is such that it is potentially a more favorable fuel because of reduced rates of oxidation and thermal polymerization. This paper will report on results of short and long term engine tests using winter rape, diesel, and commercial additives as the components. Selection of mixtures for long term screening tests was based on laboratory studies which included high temperature oxidation studies and temperature-viscosity data. Fuel temperature has been monitored at the outlet of the injector nozzle on operating engines so that viscosity comparisons at the actual injector temperature can be made. 1 figure, 3 tables.« less

The high-quality, high-yield rape (Brassica napus L. cv. Xiangnongyou 571) was chosen as the experimental material to undergo seedling stage soil cultivation and solution cultivation. This study was aimed to investigate the effects of sulfur (S) on the fraction and species of amend selenium (Se) in soil by applying S fertilizer, and to reveal the mechanism through which S controls the Se uptake of rape. The results showed that applications of both Se at 5 mg.kg-1 and S at 150 mg.kg-1 could provide some boost to rape growth, however such boost was unremarkable; S application could significantly reduce Se content in shoots and roots by as much as 64. 0% and 39. 1% , respectively; S application could significantly decrease the pH value and increase the organic matter content by as much as 0. 65 units and 1.76 g.kg-1 , respectively; S application could significantly decrease soluble Se and Fe/Mn oxide-bound Se, and significantly increase organic matter-bound Se, however, there was no remarkable effect on exchangeable and residual Se. S could significantly decrease the content of Se(IV) in the soluble Se and significantly increase the content of Se(IV) in the exchangeable Se, with remarkable decrease in Se(VI) content in both fractions, and no remarkable effect on Se(II). S had a profound effect on the uptake of Se by rape seedlings when Se( IV) and Se( VI) were applied. The Se contents in shoot and root of the Se( VI)-treated rape were 7.3 and 3.2 times respectively as high as that of the Se( IV)-treated rape, while with a S rate of 2 mmolL-1, their Se contents were lower than 32.6% and 8.7% of that of the Se(IV)-treated rape. In conclusion, in addition to improving crop growth, appropriate amount of S fertilizer could also reduce soil pH and increase organic content, causing available Se in soil to be Fe/Mn oxide-bound and organic matter-bound, and retarding its transformation to Se( VI), thus reducing Se uptake by rape. This has significant value for regulation of Se

Rape Prevention With College Men

This study evaluates the effectiveness of a theoretically based rape prevention intervention with college men who were at high or low risk to perpetrate sexually coercive behavior. Participants (N = 146) are randomly assigned to the intervention or control group. Outcomes include rape myth acceptance, victim empathy, attraction to sexual aggression, sex-related alcohol expectancies, and behavioral indicators, measured across three time points. Positive effects are found for rape myth acceptance, victim empathy, attraction to sexual aggression, and behavioral intentions to rape. Only rape myth acceptance and victim empathy effects sustain at the 5-week follow-up. High-risk men are generally unaffected by the intervention although low-risk men produced larger effects than the entire sample. Results suggest rape prevention studies must assess risk status moderation effects to maximize prevention for high-risk men. More research is needed to develop effective rape prevention with men who are at high risk to rape. PMID:18591366

We examined the association between rape myth acceptance (RMA) and reporting rapes to the police. Situational characteristics of the rape (e.g., stranger attack, injury) are known predictors of reporting, but no existing studies have examined the association between beliefs about rape and reporting. In addition, most studies of RMA do not assess victimization history. Incarcerated women experience high rates of sexual assaults prior to incarceration. We recruited 74 rape survivors from a northwestern state prison. Results suggest that women who endorsed higher levels of RMA were less likely to report their rapes to police; however, participants endorsed few rape myths.

Ecosystem processes in agricultural landscapes are often triggered by resource availability in crop and noncrop habitats. We investigated how oilseed rape (OSR; Brassica napus, Brassicaceae) affects noncrop plants in managed systems and semi-natural habitat, using trophic interactions among wild mustard (Sinapis arvensis, Brassicaceae), rape pollen beetles (Meligethes aeneus, Nitidulidae) and their parasitoids (Tersilochus heterocerus, Ichneumonidae). We exposed wild mustard as phytometer plants in two cropland habitat types (wheat field, field margin) and three noncrop habitat types (fallow, grassland, wood margin) across eight landscapes along a gradient from simple to complex (quantified as % arable land). Both landscape and local factors affected the abundance of rape pollen beetles and parasitoids. Rape pollen beetle infestation and parasitism rates on these plants were lower in noncrop habitats and higher in wheat fields and field margins, whereas beetles and parasitoids responded differently to landscape scale parameters. We found the hypothesized spillover from OSR crop onto wild plants in surrounding habitats only for parasitoids, but not for pollen beetles. Parasitism rates were not related to landscape simplification, but benefited from increasing proportions of OSR. In contrast, rape pollen beetles benefited from simple landscape structures, presumably due to multi-annual population build-ups resulting from long-term OSR planting (as part of the crop rotation). In conclusion, we showed that spillover from cropland affects parasitism rates on related wild plants outside cropland, which has not been shown so far, but can be expected to be a widespread effect shaping noncrop food webs.

Abortion and rape.

The letter is an answer to a previous letter which appeared in the same journal and which was discrediting, according to the author of this letter, the Royal Commission on Contraception, Sterilization, and Abortion. The earlier letter refutes a quote from "Abortion and Social Justice" used by the Commission, regarding the situation in Colorado after rape became an indication for abortion. The quote reports that although between 1967-1971 the number of abortions for rape totalled 290, no rapist was charged or convicted for the crime. However, according to the author of this letter, the actual quote reads somewhat differently, and states that, during the same period, "no rapist was ever charged with his crime, much less convicted of it, which casts some real doubts on the reality of the alleged rapes." The meaning of this passage is that none of the alleged rapists had actually caused the 290 pregnancies. From records and government statistics it is possible to count about 3300 cases of rape known to the police in Colorado for the years 1967-1971. To suggest that none of these cases were charged or convicted is ridiculous. The author also states that rape as an indication for abortion will lead to abuse of the law, and that pregnancy for actual rape is rare.

The mechanism associated with improvement of soil nutritional status by oilseed rape crop, leading to better performance of rice crop, in rice-oilseed rape cropping systems is little known. The present study was aimed to test the hypothesis that earthworm casts produced during oilseed rape-growing season have positive effects on grain yield and fertilizer nitrogen (N) utilization in the subsequent flooded rice crop. A 15N-tracing pot experiment was conducted to determine the effects of earthworm casts collected from oilseed rape fields on yield attributes in rice and the fate of fertilizer N. Soil treated with earthworm casts (soil: earthworm casts = 4: 1, w/w) (EC1) produced 39% higher grain yield than soil only (EC0). EC1 had 18% more panicle number and 10% higher spikelet filling percentage than EC0. Aboveground biomass and harvest index were higher in EC1 than in EC0 by 20% and 15%, respectively. SPAD values in flag leaves were 10% and 22% higher under EC1 than EC0 at 15 and 20 days after heading, respectively. EC1 had 19% higher total N uptake and 18% higher physiological N-use efficiency than EC0. These positive effects of earthworm casts on yield attributes offset negative effects of decreasing N rate from 0.74 g pot-1 (equivalent to the recommended field rate of 150 kg ha-1) to 0.44 g pot-1 (equivalent to 60% of the recommended rate). Fertilizer N retention rate was 7% higher while fertilizer N loss rate was 6% lower in EC1 than in EC0. Our study suggests that earthworm casts produced during oilseed rape-growing season are expected to have the following benefits on the subsequent flooded rice system: (1) improving growth and physiological processes in rice plants and consequently increasing rice grain yield, and (2) increasing fertilizer N retention rate and hence decreasing fertilizer N loss rate and reducing environmental risk.

Low crop plant population densities promote pollen-mediated gene flow in spring wheat (Triticum aestivum L.).

Transgenic wheat is currently being field tested with the intent of eventual commercialization. The development of wheat genotypes with novel traits has raised concerns regarding the presence of volunteer wheat populations and the role they may play in facilitating transgene movement. Here, we report the results of a field experiment that investigated the potential of spring wheat plant population density and crop height to minimize gene flow from a herbicide-resistant (HR) volunteer population to a non-HR crop. Pollen-mediated gene flow (PMGF) between the HR volunteer wheat population and four conventional spring wheat genotypes varying in height was assessed over a range of plant population densities. Natural hybridization events between the two cultivars were detected by phenotypically scoring plants in F(1) populations followed by verification with Mendelian segregation ratios in the F(1:2) families. PMGF was strongly associated with crop yield components, but showed no association with flowering synchrony. Maximum observed PMGF was always less than 0.6%, regardless of crop height and density. The frequency of PMGF in spring wheat decreased exponentially with increasing plant population density, but showed no dependence on either crop genotype or height. However, increasing plant densities beyond the recommended planting rate of 300 cropped wheat plants m(-2) provided no obvious benefit to reducing PMGF. Nevertheless, our results demonstrate a critical plant density of 175-200 cropped wheat plants m(-2) below which PMGF frequencies rise exponentially with decreasing plant density. These results will be useful in the development of mechanistic models and best management practices that collectively facilitate the coexistence of transgenic and nontransgenic wheat crops.

Rape Beyond Crime.

PubMed

Kaplan, Margo

2017-02-01

Public health experts agree that sexual violence constitutes a significant public health issue. Yet criminal law dominates rape law almost completely, with public health law playing at best a small supporting role. Recent civil law developments, such as university disciplinary proceedings, similarly fixate on how best to find and penalize perpetrators. As a result, rape law continues to spin its wheels in the same arguments and obstacles. This Article argues that, without broader cultural changes, criminal law faces a double bind: rape laws will either be ineffective or neglect the importance of individual culpability. Public health law provides more promising terrain for rape prevention because it is a strong legal framework that can engage the complex causes of rape, including the social norms that promote sexual aggression. While criminal law can only punish bad behavior, public health interventions can use the more effective prevention strategy of promoting positive behaviors and relationships. They can also address the myriad sexual behaviors and social determinants that increase the risk of rape but are outside the scope of criminal law. Perhaps most importantly, public health law relies on evidence-based interventions and the expertise of public health authorities to ensure that laws and policies are effective. Transforming rape law in this way provides a framework for legal feminism to undertake the unmet challenge of "theorizing yes," that is, moving beyond how to protect women’s right to refuse sex and toward promoting and exploring positive models of sex. Criminal law is simply incapable of meeting this challenge because it concerns only what sex should not be. A public health framework can give the law a richer role in addressing the full spectrum of sexual attitudes and behaviors.

The rape stem weevil, Ceutorhynchus napi Gyll., is a serious pest of winter oilseed rape (Brassica napus L.) crops in Europe causing severe yield loss. In currently used oilseed rape cultivars no resistance to C. napi has been identified. Resynthesized lines of B. napus have potential to broaden the genetic variability and may improve resistance to insect pests. In this study, the susceptibility to C. napi of three cultivars, one breeding line and five resynthesized lines of oilseed rape was compared in a semi-field plot experiment under multi-choice conditions. Plant acceptance for oviposition was estimated by counting the number of C. napi larvae in stems. The larval instar index and the dry body mass were assessed as indicators of larval performance. The extent of larval feeding within stems was determined by the stem injury coefficient. Morphological stem traits and stem contents of glucosinolates were assessed as potential mediators of resistance. The resynthesized line S30 had significantly fewer larvae than the cultivars Express617 and Visby and the resynthesized lines L122 and L16. The low level of larval infestation in S30 was associated with a low larval instar and stem injury index. Low numbers of larvae were not correlated with the length or diameter of stems, and the level of stem glucosinolates. As indicated by the low larval infestation and slow larval development the resistance of S30 to C. napi is based on both antixenotic and antibiotic properties of the genotypes. The resynthesized line S30 should therefore be introduced into B. napus breeding programs to enhance resistance against C. napi. PMID:28686731

Approximately 65% of anthropogenic emissions of N2O, a potent greenhouse gas, originate from soils at global scale, and particularly after N fertilisation of the main crops in Europe. Thanks to their capacity to fix atmospheric N2 through biological fixation, legumes allow to reduce N fertilizer use, and possibly N2O emission. Nevertheless, the decomposition of crop organic matter during the crop cycle and during the residue decomposition, and possibly the N fixation process itself, could lead to N2O emissions. The objective of this study was to quantify N2O emissions from a dry pea crop (Pisum sativum, harvested at maturity) and from the subsequent crops in comparison with N2O emissions from wheat and oilseed-rape crops, fertilized or not, in various rotations. A field experiment was conducted during 4 consecutive years, aiming at comparing the emissions during the pea crop, in comparison with those during the wheat (fertilized or not) or oilseed rape crops, and after the pea crop, in comparison with other preceding crops. N2O fluxes were measured using static chambers. In spite of low N2O fluxes, mainly linked with the site soil characteristics, fluxes during the crop were significantly lower for pea and unfertilized wheat than for fertilized wheat and oilseed rape. The effect of the preceding crop was not significant, while soil mineral N at harvest was higher after pea. These results, combined with the emission reduction allowed by the production and transport of the N fertiliser not applied on the pea crop, should be confirmed in a larger range of soil types. Nevertheless, they demonstrate the absence of N2O emission linked to the symbiotic N fixation process, and allow us to estimate the decrease of N2O emissions to 20-25% by including one pea crop in a three-year rotation. At a larger scale, this reduction of GHG emissions at field level has to be cumulated with the reduction of GHG emissions linked with the lower level of production and transport of the N

Contact with Counter-Stereotypical Women Predicts Less Sexism, Less Rape Myth Acceptance, Less Intention to Rape (in Men) and Less Projected Enjoyment of Rape (in Women).

Intergroup contact-(positive) interactions with people from different social groups-is a widely researched and strongly supported prejudice-reducing mechanism shown to reduce prejudice against a wide variety of outgroups. However, no known previous research has investigated whether intergroup contact can also reduce sexism against women. Sexism has an array of negative outcomes. One of the most detrimental and violent ones is rape, which is both justified and downplayed by rape myth acceptance. We hypothesised that more frequent, higher quality contact with counter-stereotypical women would predict lower levels of sexism and thus less rape myth acceptance (in men) and less sexualised projected responses to rape (in women). Two studies using online surveys with community samples supported these hypotheses. In Study 1, 170 male participants who experienced more positive contact with counter-stereotypical women reported less intention to rape. Similarly, in Study 2, 280 female participants who experienced more positive contact with counter-stereotypical women reported less projected sexual arousal at the thought of being raped. Thus, the present research is the first known to show that contact could be a potential tool to combat sexism, rape myth acceptance, intentions to rape in men, and sexualisation of rape by women.

Sclerotinia stem rot (SSR) is an increasing threat to winter oilseed rape (OSR) in Germany and other European countries due to the growing area of OSR cultivation. A forecasting model was developed to provide decision support for the fungicide spray against SSR at flowering. Four weather variables-air temperature, relative humidity, rainfall, and sunshine duration-were used to calculate the microclimate in the plant canopy. From data reinvestigated in a climate chamber study, 7 to 11 degrees C and 80 to 86% relative humidity (RH) were established as minimum conditions for stem infection with ascospores and expressed as an index to discriminate infection hours (Inh). Disease incidence (DI) significantly correlated with Inh occurring post-growth stage (GS) 58 (late bud stage) (r(2) = 0.42, P crop has passed GS 58. The second tier provides a field-site-specific, economy-based recommendation. Based on costs of spray, expected yield, and price of rapeseed, the number of Inh corresponding to DI at the economic damage threshold (Inh(i)) is calculated. A decision to spray is proposed when Inh >/= Inh(i). Historical field data (1994 to 2004) were used to assess the impact of agronomic factors on SSR incidence. A 2-year crop rotation enhanced disease risk and, therefore, lowered the infection threshold in the model by a factor of 0.8, whereas in 4-year rotations, the threshold was elevated by a factor 1.3. Number of plants per square meter, nitrogen fertilization, and soil management did not

Rape shield laws, which limit the introduction of sexual history evidence in rape trials, challenge the view that women with extensive sexual histories more frequently fabricate charges of rape than other women. The present study examined the relationship between women's actual sexual history and their reporting rape in hypothetical scenarios. Female participants (college students and a community sample, which included women working as prostitutes and topless dancers, and women living in a drug and alcohol rehabilitation center) imagined themselves in dating scenarios that described either a legally definable act of rape or consensual sexual intercourse. Additionally, within the rape scenarios, level of consensual intimate contact (i.e., foreplay) preceding rape was examined to determine its influence on rape reporting. Women were less likely to say that they would take legal action in response to the rape scenarios if they had extensive sexual histories, or if they had consented to an extensive amount of intimate contact before the rape. In response to the consensual sexual intercourse scenarios, women with more extensive sexual histories were not more likely to say that they would report rape, even when the scenario provided them with a motive for seeking revenge against their dating partner.

Prevention of post-rape psychopathology: preliminary findings of a controlled acute rape treatment study.

Violent sexual assault such as rape typically results in extremely high levels of acute distress. The intensity of these acute psychological reactions may play a role in later recovery, with higher levels of immediate distress associated with poorer outcome. Unfortunately, post-rape forensic evidence collection procedures may serve to increase, rather than reduce initial distress, potentially exacerbating future psychopathology. To address these concerns, an acute time-frame hospital-based video intervention was developed to: (a) minimize anxiety during forensic rape exams, and (b) prevent post-rape posttraumatic stress disorder (PTSD), panic, and anxiety. Preliminary data indicated that (1) psychological distress at the time of the exam was strongly related to PTSD symptomatology 6 weeks post-rape, and (2) the video intervention successfully reduced distress during forensic exams.

2003-01-01

The determination of critical period of weed control in oilseed rape is necessary to know the weed control period. To determine the critical period, two fields experiments were carried out during 1995-96 growth season in Loukkos and Saïs regions at two oilseed densities (D1 = 24 and D2 = 36 plants m(-2)). Ten treatments corresponding to plots left weed free or weeded plots until four leaves, flowers bud, flowering, puds formation, and maturity stages of oilseed rape were tested. Density and biomass of weeds were determined at each oilseed stages. Results showed that weed density and biomass were higher in Saïs than in Loukkos sites. For a 10% yield loss, critical period of weed control in Loukkos was from 458 to 720 degree days after emergence (D degrees AE) and from 480 to 720 D degrees AE in oilseed conducted at densities D1 and D2, respectively. In Saïs, critical period of weed control was from 474 to 738 D degrees AE and from 468 to 675 D degrees AE in oilseed conducted at D1 and D2, respectively. It was concluded that the length of the critical period of weed control in oilseed rape grain yield seems to be dependant of the level of the infestation.

2017-01-01

Oilseed rape (Brassica napus) is an important combinable break crop in the UK, which is largely protected from arthropod pests by insecticidal chemicals. Despite ongoing debate regarding the use of neonicotinoids, the dominant seed treatment ingredients used for this crop, there is little publicly available data comparing the efficacy of insecticides in controlling key arthropod pests or comparing the impacts on non-target species and the wider environment. To provide an insight into these matters, a UK-wide expert survey targeting agronomists and entomologists was conducted from March to June 2015. Based on the opinions of 90 respondents, an average of 20% yield loss caused by the key arthropod pests was expected to have occurred in the absence of insecticide treatments. Relatively older chemical groups were perceived to have lower efficacy for target pests than newer ones, partly due to the development of insecticide resistance. Without neonicotinoid seed treatments, a lack of good control for cabbage stem flea beetle was perceived. Wide spectrum foliar insecticide sprays were perceived to have significantly greater negative impacts than seed treatments on users' health, natural enemies, pollinators, soil and water, and many foliar active ingredients have had potential risks for non-target arthropod species in UK oilseed rape fields for the past 25 years. Overall, 72% of respondents opposed the neonicotinoid restriction, while 10% supported it. Opposition and support of the restriction were largely based on concerns for pollinators and the wider environment, highlighting the uncertainty over the side effects of neonicotinoid use. More people from the government and research institutes leaned towards neutrality over the issue, compared to those directly involved in growing the crop. Neonicotinoid restriction was expected to result in greater effort and expenditure on pest control and lower production (0-1 t/ha less). Alternatives for future oilseed rape protection

Rape avoidance behavior among Slovak women.

Prokop, Pavol

2013-05-28

Rape has been a recurrent adaptive problem for many species, including humans. Rape is costly to women in terms of disease transmission, partner abandonment, and unwanted pregnancy (among other costs). Therefore, behavioral strategies which allow women to avoid coercive men may have been favored by selection. In line with this evolutionary reasoning, the current research documented that physically stronger women and those in a committed romantic relationship reported more rape avoidance behavior. In addition, virgin women tended to perform more rape avoidance behavior compared with their non-virgin counterparts. Women with high conception risk perceived themselves as physically stronger, which may protect them against a potential rapist. Fear of unwanted pregnancy from rape decreased as age increased, reflecting higher fertility among younger participants. However, older women reported more rape avoidance behavior, which contradicts evolutionary predictions. The results provide some support for evolutionary hypotheses of rape avoidance behavior which suggest that woman's perception of rape is influenced by parental investment and perceived physical condition.

Intensive agricultural system with high input of fertilizer results in high agricultural output. However, excessive fertilization in intensive agricultural system has great potential to cause nitrate and heavy metal accumulation in soil, which is adverse to human health. The main objective of the present study was to observe the effects of intercropping and inoculation of endophytic bacterium Acinetobacter calcoaceticus Sasm3 on phytoremediation of combined contaminated soil in oilseed rape (Brassica napus L.). The results showed that with Sasm3 inoculation, the biomass of rape was increased by 10-20% for shoot, 64% for root, and 23-29% for seeds while the nitrate accumulation in rape was decreased by 14% in root and by 12% in shoot. The cadmium concentration in rape increased significantly with mono-inoculating treatment, whereas it decreased significantly after intercropping treatment. By denaturing gradient gel electrophoresis (DGGE) and real-time quantitative PCR analysis, the diversity of bacterial community and the number of nirS and nirK gene copies increased significantly with inoculation or/and intercropping treatment. In conclusion, the endophytic bacterium Sasm3-inoculated intercropping system not only improved the efficiency of clearing cadmium from soil without obstructing crop production, but also improved the quality of crop.

Biodiversity of nematofauna of oilseed rape (Brassica napus L.).

Few data is available on the nematodes found in Brassicaceae, except for the most important plant parasite. However, studying the structure of nematofauna could be an important database for the soil quality and in order to assess the effects of future disturbance. This is particularly important considering that the diffusion of the canola crop in the world is increasing because of its use as a bio-diesel. Very diffused is also the Bt variety of oil seed rape, and, in this case, the study of the impact on the soil health and on bio-diversity is essential. In this research we have analyzed the nematode community, used as a bio-indicator of the soil condition. The nematofauna found in canola (Brassica napus var. oleifera) fields located in Southern Italy (Metaponto - MT) was investigated. The nematode community was studied considering its abundance, genus composition and trophic structure. Maturity and biodiversity indices were also calculated. A total of 5286 nematodes were extracted. They belong to 14 families and 24 genera. Bacterial and fungal feeders, 50.18% and 42.90% of the total respectively, dominated the trophic structure. Aphelencus is the most abundant genus (23.71%) followed by Acrobeloides (20.49%) and Aphelencoides (19.18%). Among plant feeders (6.59%), Pratylenchus is the dominant genus (2.20%) and Tylenchidae the main family (3.54%). No infestation of Meloidogyne, Heterodera or Naboccus, important plant-parasitic nematodes of canola crops, was recorded. Other important phytophagous were Helycotylenchus (0.5%), Trichotylenchus (0.5%) and Filenchus (0.9%). All of them had an abundance level below injury level. The indices of biodiversity are rather low (H'=0.93, J'=0.67), as is typical for agro ecosystems. However, the nematofauna community is quite well structured (N2=6.31, D=0.16) and the maturity index rather high (EMI=1.94). These values demonstrate that oilseed rape has a lower impact on the soil compared to other crop systems and that it could be

Increased phytochrome B alleviates density effects on tuber yield of field potato crops.

2003-12-01

The possibility that reduced photomorphogenic responses could increase field crop yield has been suggested often, but experimental support is still lacking. Here, we report that ectopic expression of the Arabidopsis PHYB (phytochrome B) gene, a photoreceptor involved in detecting red to far-red light ratio associated with plant density, can increase tuber yield in field-grown transgenic potato (Solanum tuberosum) crops. Surprisingly, this effect was larger at very high densities, despite the intense reduction in the red to far-red light ratios and the concomitant narrowed differences in active phytochrome B levels between wild type and transgenics at these densities. Increased PHYB expression not only altered the ability of plants to respond to light signals, but they also modified the light environment itself. This combination resulted in larger effects of enhanced PHYB expression on tuber number and crop photosynthesis at high planting densities. The PHYB transgenics showed higher maximum photosynthesis in leaves of all strata of the canopy, and this effect was largely due to increased leaf stomatal conductance. We propose that enhanced PHYB expression could be used in breeding programs to shift optimum planting densities to higher levels.

Child rape: facets of a heinous crime.

This article discusses the extent of child rape in India, case studies of girl children in legal procedures, rape settings and perpetrators, public morality, and the nature of rape laws in India. It is concluded that there is no safe place for children. Currently, rapists are allowed to go free or are acquitted. Prevention and control of child rape must involve punishment of rapists. It is not appropriate that society ostracize the victim and her family. Victims should not remain silent. National Crime Records Bureau statistics reveal increases in rape during 1986-91. State figures are given for 1986-88. Madhya Pradesh had the highest reported incidence of rape in 1988. In 1993, Madhya Pradesh had a total of 2459 rapes. Nationally, 10,425 women were reported as raped in 1991. 51.7% were 16-30 years old. There were 1099 cases of pedophilia in 1991, which was an increase over 1990. Over 50% of the pedophilia cases were reported in Uttar Pradesh. The record of convictions shows very low figures. 1992 trial results of 276 rape cases indicated that only 46 persons were convicted. Victims suffer from psychological effects of embarrassment, disgust, depression, guilt, and even suicidal tendencies. There is police and prosecution indifference as well as social stigma and social ostracism of the victim and her family. Many cases go unreported. The case studies illustrate the difficulties for the victim of experiencing the rape and the social responses: police harassment, shame and fear, and occasionally public outrage. The case studies illustrate rape in familiar settings, such as schools, family homes, and neighbors and friends' homes; rape by policemen; and rape by political influentials. Most offenders are young, married, and socioeconomically poor. Mass media portrayals fuel the frustrations of poor and lonely men in cities. Rapists exhibit anti-social behavior or psychopathology. Sexual offenses are related to society's moral values.

2014-03-01

The impact of victim resistance on rape completion and injury was examined utilizing a large probability sample of sexual assault incidents, derived from the National Crime Victimization Survey (1992-2002), and taking into account whether harm to the victim followed or preceded self-protection (SP) actions. Additional injuries besides rape, particularly serious injuries, following victim resistance are rare. Results indicate that most SP actions, both forceful and nonforceful, reduce the risk of rape completion, and do not significantly affect the risk of additional injury.

The purpose of this research is to explore the negotiation strategies of college women as they interpret ambiguous rape scenarios. In focus groups, 1st- and 4th-year college women were presented with a series of three vignettes depicting incidents that meet the legal criteria for rape yet are ambiguous due to the presence of cultural rape myths, contexts involving alcohol consumption, varying degrees of consent, and a known perpetrator. These contexts are critical in understanding how college women define rape. Key findings indicated many of these college women utilized rape myths and norms within their peer groups to interpret rape scenarios.

2009-07-01

Herbicide-resistant crop technology could provide new management strategies for the control of parasitic plants. Three herbicide-resistant oilseed rape (Brassica napus L.) genotypes were used to examine the response of attached Cuscuta campestris Yuncker to glyphosate, imazamox and glufosinate. Cuscata campestris was allowed to establish on all oilseed rape genotypes before herbicides were applied. Unattached seedlings of C. campestris, C. subinclusa Durand & Hilg. and C. gronovii Willd. were resistant to imazamox and glyphosate and sensitive to glufosinate, indicating that resistance initially discovered in C. campestris is universal to all Cuscuta species. Glufosinate applied to C. campestris attached to glufosinate-resistant oilseed rape had little impact on the parasite, while imazamox completely inhibited C. campestris growth on the imidazolinone-resistant host. The growth of C. campestris on glyphosate-resistant host was initially inhibited by glyphosate, but the parasite recovered and resumed growth within 3-4 weeks. The ability of C. campestris to recover was related to the quality of interaction between the host and parasite and to the resistance mechanism of the host. The parasite was less likely to recover when it had low compatibility with the host, indicating that parasite-resistant crops coupled with herbicide resistance could be highly effective in controlling Cuscuta.

In recent years, wood vinegar has been widely used in the agricultural production. It can be used as the soil amendment, antibacterial agent and organic fertilizer. This study investigated the effect of wood vinegar on rape (Brassica napus L.) seed germination. The results in this study showed that 1% (v/v) wood vinegar had the greatest inhibition effect on the seed germination of rape (Brassica napus L.). The wood vinegar (WV) and the distilled wood vinegar at 98 - 130 °C (D2) significantly inhibited seed germination by 100%, compared to the control treatment. However, the distilled wood vinegar (D1) had significantly increased the shoot length and root length by 58.4% and 31.7%, respectively. These positive effects could be attributed to the improved soil fertility, increased nutrient supply, and further stimulated plant growth. Overall, the D1 could be a promising soil amendment to promote plants growth and enhance crop yields. Effect of adding different components of distilled wood vinegar on the seed germination of rape

Introducing the Date and Acquaintance Rape Avoidance Scale.

2016-01-01

We present the Date and Acquaintance Rape Avoidance Scale (DARAS). The DARAS is a measure of a woman's behaviors used to avoid date and acquaintance rape. Three factor structures were possible. The DARAS may have measured several factors related to alcohol and drug use, self-defense, and date behaviors; 2 factors related to behaviors to avoid acquaintance versus date rape; or a single factor that represented general vigilance. The data revealed a highly reliable, 63 item single factor that was correlated with stranger rape avoidance, rejection of rape myths, hostile sexist beliefs about men, and benevolent sexist beliefs about women. The creation of the DARAS adds to the growing body of research on rape avoidance. The DARAS is key to understanding the behaviors women employ to avoid date rape. Rather than placing the responsibility for rape on the victim, the DARAS was developed as a theoretical and applied tool that can be used to improve theory and construct rape education and prevention programs.

1984-02-01

Data are presented concerning the ethics of exposing undergraduate students to pornographic rape portrayals followed by a debriefing designed to dispel a number of rape myths. One hundred fifty males and females were randomly assigned to read pornographic stories. Some of these depicted a rape, whereas others depicted mutually consenting intercourse. Afterwards, those exposed to the rape version were given a debriefing which included statements concerning the true horror of rape and the existence of rape myths. About 10 days later, a "Public Survey" ostensibly conducted by a local committee of citizens was given to subjects in their classes. A postexperimental questionnaire confirmed that participants were not aware that this survey was related to the earlier phase of the research. As part of the survey, subjects were presented with actual newspaper articles about which their opinions were solicited. One of these articles, the dependent measure of the study, concerned rape. Subjects indicated their reactions to this article and their opinions about the general causes of rape. The results indicated that those exposed to the rape depictions followed by a "rape debriefing" were less accepting of certain rape myths than subjects exposed to mutually consenting intercourse depictions. Implications of the data for future research in this area are discussed both in terms of work focusing on the potential antisocial impact of violent pornography and of research specifically designed to identify the conditions most likely to change acceptance of rape myths.

Tocopherols (Tocs) are vital scavengers of reactive oxygen species (ROS) and important seed oil quality indicators. Nitrogen (N) is one of the most important fertilizers in promoting biomass and grain yield in crop production. However, the effect of different sources and application rates of N on seed Toc contents in oilseed rape is poorly understood. In this study, pot trials were conducted to evaluate the effect of two sources of N fertilizer (urea and ammonium nitrate). Each source was applied to five oilseed rape genotypes (Zheshuang 72, Jiu-Er-1358, Zheshuang 758, Shiralee, and Pakola) at three different application rates (0.41 g/pot (N1), 0.81 g/pot (N2), and 1.20 g/pot (N3)). Results indicated that urea increased α-, γ-, and total Toc (T-Toc) more than did ammonium nitrate. N3 was proven as the most efficient application rate, which yielded high contents of γ-Toc and T-Toc. Highly significant correlations were observed between Toc isomers, T-Toc, and α-/γ-Toc ratio. These results clearly demonstrate that N sources and application rates significantly affect seed Toc contents in oilseed rape. PMID:24510711

Dynamic mapping and monitoring of crop harvest on a large spatial scale will provide critical information for the formulation of optimal harvesting strategies. This study evaluates the feasibility of C-band polarimetric synthetic aperture radar (PolSAR) for monitoring the harvesting progress of oilseed rape (Brassica napus L.) fields. Five multitemporal, quad-pol Radarsat-2 images and one optical ZY-1 02C image were acquired over a farmland area in China during the 2013 growing season. Typical polarimetric signatures were obtained relying on polarimetric decomposition methods. Temporal evolutions of these signatures of harvested fields were compared with the ones of unharvested fields in the context of the entire growing cycle. Significant sensitivity was observed between the specific polarimetric parameters and the harvest status of oilseed rape fields. Based on this sensitivity, a new method that integrates two polarimetric features was devised to detect the harvest status of oilseed rape fields using a single image. The validation results are encouraging even for the harvested fields covered with high residues. This research demonstrates the capability of PolSAR remote sensing in crop harvest monitoring, which is a step toward more complex applications of PolSAR data in precision agriculture.

Possible effects of clothianidin seed-treated oilseed rape on honey bee colonies were investigated in a large-scale monitoring project in Northern Germany, where oilseed rape usually comprises 25-33 % of the arable land. For both reference and test sites, six study locations were selected and eight honey bee hives were placed at each location. At each site, three locations were directly adjacent to oilseed rape fields and three locations were situated 400 m away from the nearest oilseed rape field. Thus, 96 hives were exposed to fully flowering oilseed rape crops. Colony sizes and weights, the amount of honey harvested, and infection with parasites and diseases were monitored between April and September 2014. The percentage of oilseed rape pollen was determined in pollen and honey samples. After oilseed rape flowering, the hives were transferred to an extensive isolated area for post-exposure monitoring. Total numbers of adult bees and brood cells showed seasonal fluctuations, and there were no significant differences between the sites. The honey, which was extracted at the end of the exposure phase, contained 62.0-83.5 % oilseed rape pollen. Varroa destructor infestation was low during most of the course of the study but increased at the end of the study due to flumethrin resistance in the mite populations. In summary, honey bee colonies foraging in clothianidin seed-treated oilseed rape did not show any detrimental symptoms as compared to colonies foraging in clothianidin-free oilseed rape. Development of colony strength, brood success as well as honey yield and pathogen infection were not significantly affected by clothianidin seed-treatment during this study.

The UK Farm Scale Evaluations (FSEs) have shown that the use of broad spectrum herbicides on genetically modified herbicide-tolerant (GMHT) crops can have dramatic effects on weed seed production compared to management of conventional varieties. Here, we use FSE data and information on bird diets to determine how GMHT cropping might change the food resources available to farmland birds. More than 60 fields of each of four crops, spring- and winter-sown oilseed rape, beet and maize, were split, one half being sown with a conventional variety, the other with a GMHT variety. Seed rain from weeds known to be important in the diets of 17 granivorous farmland bird species was measured under the two treatments. In beet and spring oilseed rape, rain of weed seeds important in the diets of 16 bird species was significantly reduced in GMHT compared to conventional halves; for no species did it increase. In winter oilseed rape, rain of weed seeds important in the diets of 10 species was significantly reduced in GMHT halves; for only one species did it increase significantly. By contrast, in maize, rain of weed seeds important in the diets of seven species was significantly greater in GMHT halves; for no species was it reduced. Treatment effects for the total weed seed energy available to each bird species were very similar to those for seed rain alone. Measuring the effects on individual bird species was outside the scope of this study. Despite this, these results suggest that should beet, spring and winter rape crops in the UK be largely replaced by GMHT varieties and managed as in the FSEs, this would markedly reduce important food resources for farmland birds, many of which declined during the last quarter of the twentieth century. By contrast, GMHT maize would be beneficial to farmland birds. PMID:16822753

The relationship between male rape myth acceptance, female rape myth acceptance, attitudes toward gay men, a series of gender role and sexism measures, victim blame and assault severity were investigated. It was predicted that men would display more negative, stereotypical attitudes than women and that male rape myth endorsement would be related to, and predicted by, the other attitude and attribution scales. Respondents comprised 323 undergraduates (146 males and 177 females) from a large University in the Northwest of England. Results broadly conformed to predictions, with men generally more negative than women, and male rape myth acceptance significantly related to female rape myth acceptance, negative attitudes about gay men, gender role attitudes, and victim blame. Furthermore, male rape myth acceptance was predicted by female rape myth acceptance, gender attitudes, and victim blame. Methodological issues and implications for future work and those working with victims are discussed.

Introduction: In India, girl is raped every 20 min. The majority of reports reveals youth is vulnerable group for rape victimization. A set of prejudicial, stereotyped, or false beliefs about rape, rape victims, and rapist exist in the community. Aims/Objectives: To study the attitude and myths toward rape among college going students of Surat City. Materials and Methods: College students of various streams were participated in the study based on attitude toward rape scale (21 items) and updated Illinois Rape Myth Acceptance Scale (22 items). A total of 332 participants from three different colleges of the city took part in the survey. Data analysis was done with the SPSS version 19. Results: Among the responders, 61.75% were female. Mean age of participants was 20.22 ± 1.27 years. Almost two-third (73%) of female participants and 42% of the male participants disagreed with the myth that “When a woman says ‘no’ she really means ‘yes’.” Around 30% of the participants were uncertain about the myth that “A woman cannot be raped by someone she previously knew or had sex with.” While almost 35% of participants believed that “Most rapes are carried out by strangers.” Strong sexual desire of guys, drunkenness, and girl's clothes were reported to be factors that provoke rape by 50%, 40%, and 33% of respondents, respectively, around 95% of female and 92% of male participants think that 7-year imprisonment for rape is not enough. Conclusions: Rape myths are found to be highly prevalent among youth and higher among males. PMID:28529364

Wilson, Laura C; Miller, Katherine E

Many sexual violence survivors do not label their experiences as rape but instead use more benign labels, such as "bad sex" or "miscommunication." A meta-analysis was conducted to estimate the mean prevalence of unacknowledged rape and to inform our understanding of methodological factors that influence the detection of this phenomenon. Studies were identified using PsycINFO, PubMED, and PILOTS and were required to report the percentage of unacknowledged rape that had occurred since the age of 14 among female survivors. Moderator variables included mean participant age, recruitment source, rape definition, and unacknowledged rape definition. Twenty-eight studies (30 independent samples) containing 5,917 female rape survivors met the inclusion criteria. Based on a random effects model, the overall weighted mean percentage of unacknowledged rape was 60.4% (95% confidence interval [55.0%, 65.6%]). There was a large amount of heterogeneity, Q(29) = 445.11, p < .001, and inconsistency (I(2) = 93.5%) among included studies. The prevalence was significantly higher among college student participants compared to noncollege participants. The findings supported that over half of all female rape survivors do not acknowledge that they have been raped. The results suggest that screening tools should use behaviorally descriptive items about sexual contact, rather than using terms such as "rape." © The Author(s) 2015.

Pleiotropic effects of herbicide-resistance genes on crop yield: a review.

PubMed

Darmency, Henri

2013-08-01

The rapid adoption of genetically engineered herbicide-resistant crop varieties (HRCVs)-encompassing 83% of all GM crops and nearly 8% of the worldwide arable area-is due to technical efficiency and higher returns. Other herbicide-resistant varieties obtained from genetic resources and mutagenesis have also been successfully released. Although the benefit for weed control is the main criteria for choosing HRCVs, the pleiotropic costs of genes endowing resistance have rarely been investigated in crops. Here the available data of comparisons between isogenic resistant and susceptible varieties are reviewed. Pleiotropic harmful effects on yield are reported in half of the cases, mostly with resistance mechanisms that originate from genetic resources and mutagenesis (atrazine in oilseed rape and millet, trifluralin in millet, imazamox in cotton) rather than genetic engineering (chlorsulfuron and glufosinate in some oilseed rape varieties, glyphosate in soybean). No effect was found for sethoxydim and bromoxynil resistance. Variable minor effects were found for imazamox, chlorsulfuron, glufosinate and glyphosate resistance. The importance of the breeding plan and the genetic background on the emergence of these effects is pointed out. Breeders' efforts to produce better varieties could compensate for the yield loss, which eliminates any possibility of formulating generic conclusions on pleiotropic effects that can be applied to all resistant crops. © 2013 Society of Chemical Industry.

An understanding of the contribution of manure applications to global atmospheric N2O loading is needed to evaluate agriculture's contribution to the global warming process. Two field experiments were carried out at Dufuya wetland (19°17'S; 29°21'E, 1260 m above sea level) to determine the effects of single and split manure applications on emissions of N2O from soil during the growing seasons of two rape and two tomato crops. Two field experiments were established. In the first experiment the manure was applied in three levels of 0, 15, and 30 Mg ha(-1) as a single application just before planting of the first tomato crop. In the second experiment the 15 and 30 Mg ha(-1) manure application rates were divided into four split applications of 3.75 and 7.5 Mg ha(-1) respectively, for each of the four cropping events. Single applications of 15 and 30 Mg ha(-1) manure once in four cropping events had higher emissions of N2O than those recorded on plots that received split applications of 3.75 and 7.5 Mg ha(-1) manure at least up to the second test crop. Thereafter N2O emissions on plots subjected to split applications of manure were higher or equal to those recorded in plots that received single basal applications of 30 Mg ha(-1) applied a week before planting the first crop. Seasonal split applications of manure to wetland vegetable crops can reduce emissions of N2O at least up to the second seasonal split application.

The effects of 12 summer crop rotation treatments on population densities of Meloidogyne arenaria race 1 and on yields of subsequent spring vegetable crops were determined in microplots. The crop sequence was: (i) rotation crops during summer 1991 ; (ii) cover crop of rye (Secale cereale) during winter 1991-92; (iii) squash (Cucurbita pepo) during spring 1992; (iv) rotation crops during summer 1992; (v) rye during winter 1992-93; (vi) eggplant (Solanum melongena) during spring 1993. The 12 rotation treatments were castor (Ricinus communis), cotton (Gossypium hirsutum), velvetbean (Mucuna deeringiana), crotalaria (Crotalaria spectabilis), fallow, hairy indigo (Indigofera hirsuta), American jointvetch (Aeschynomene americana), sorghum-sudangrass (Sorghum bicolor x S. sudanense), soybean (Glycine max), horsebean (Canavalia ensiformis), sesame (Sesamum indicum), and peanut (Arachis hypogaea). Compared to peanut, the first eight rotation treatments resulted in lower (P crops may provide a means for depressing M. arenaria population densities on a short-term basis to enhance yields in a subsequent susceptible vegetable crop.

2014-01-01

Undergraduate rape disclosure recipients' and nonrecipients' sociodemographic and life experience variables, attitudes towards rape, and responses to a hypothetical rape disclosure were compared to determine differences between them. One hundred ninety-two undergraduates at 3 universities participated in this online survey between November 2011 and April 2012. Participants reported on their rape myth acceptance (RMA) and personal direct and indirect (ie, disclosure receipt) experiences with sexual assault. Participants also responded to a hypothetical rape disclosure. Disclosure recipients were more likely to report a victimization history, and less confusion and perceived ineffectiveness in helping the hypothetical victim. RMA and nonrecipient status predicted perceived victim responsibility; these variables and childhood victimization predicted confusion about helping. RMA also predicted perceived ineffectiveness of one's helping behaviors. Victimization history and female gender predicted victim empathy. These findings can inform sexual assault-related programming for undergraduates through the provision of targeted assistance and corrective information.

Near-infrared spectroscopy (NIRS) is widely used in fruits and vegetables quality evaluation. This technique is also used for the analysis of alfalfa, a crop that occupies a position of great importance in the agricultural field. In particular for the storage, moisture content is a key parameter for the crops and for this reason its monitoring is very important during the harvesting phase. Usually optical methods like NIRS are well suitable in laboratory frameworks where the specimen is properly prepared, while their application during the harvesting phase presents several diffculties. A lot of influencing factors, such as density and degree of homogeneity can affect the moisture evaluation. In this paper we present the NIRS analysis of alfalfa specimens with different values of moisture and density, as well as the obtained results. To study scattering and absorption phenomena, the forward and backward scattered light from the sample have been spectrally analyzed.

Introduction Studies indicate that a small percentage of rapes are reported to law enforcement officials. Research also suggests that rapes perpetrated by a stranger are more likely to be reported and that rapes involving drugs and/or alcohol are less likely to be reported. College women represent a unique and understudied population with regard to reporting rape. Methods In the current study, we interviewed a national sample of 2,000 college women about rape experiences in 2006. Results Only 11.5% of college women in the sample reported their most recent/only rape experience to authorities, with only 2.7% of rapes involving drugs and/or alcohol reported. Minority status (i.e., non-white race) was associated with lower likelihood of reporting, whereas sustaining injuries during the rape was associated with increased likelihood of reporting. Discussion Reporting, particularly for rapes involving drugs and alcohol, is low among college women. Implications for policy are discussed. PMID:21823952

The Psychology of the Politics of Rape: Political Ideology, Moral Foundations, and Attitudes Toward Rape.

2018-04-01

Previous research has found that conservatives and liberals emphasize different moral foundations. The purpose of these two studies was to investigate whether moral foundations mediate the relationship between political ideology and attitudes toward rape among U.S. college students. In Study 1, moral foundations fully mediated the relationship between political ideology and rape myth acceptance. Study 2 generally replicated the results of Study 1, with binding foundations demonstrating the most consistent mediating effects. These results suggest that individual differences in moral decision-making may explain the relationship between political ideology and attitudes toward rape.

2017-01-01

Nitrogen is essential for plant growth, and N fertilization allows farmers to obtain high yields and produce sufficient agricultural commodities. On the other hand, nitrogen losses potentially cause adverse effects to ecosystems and to human health. Increasing nitrogen use efficiency (NUE) is vital to solve the conflict between productivity, to secure the demand of a growing world population, and the protection of the environment. To ensure this, genetic improvement is considered to be a paramount aspect toward ecofriendly crop production. Winter oilseed rape (Brassica napus L.) is the second most important oilseed crop in the world and is cultivated in many regions across the temperate zones. To our knowledge, this study reports the most comprehensive field-based data generated to date for an empirical evaluation of genetic improvement in winter oilseed rape varieties under two divergent nitrogen fertilization levels (NFLs). A collection of 30 elite varieties registered between 1989 and 2014, including hybrids and open pollinated varieties, was tested in a 2-year experiment in 10 environments across Germany for changes in seed yield and seed quality traits. Furthermore, NUE was calculated. We observed a highly significant genetics-driven increase in seed yield per-se and, thus, increased NUE at both NFLs. On average, seed yield from modern open-pollinated varieties and modern hybrids was higher than from old open-pollinated varieties and old hybrids. The annual yield progress across all tested varieties was ~35 kg ha−1 year−1 at low nitrogen and 45 kg ha−1 year−1 under high nitrogen fertilization. Furthermore, in modern varieties an increased oil concentration and decreased protein concentration was observed. Despite, the significant effects of nitrogen fertilization, a surprisingly low average seed yield gap of 180 kg N ha−1 was noted between high and low nitrogen fertilization. Due to contrary effects of N fertilization on seed yield per-se and seed

2017-06-12

Purpose The Prison Rape Elimination Act has brought significant attention to the issue of sexual victimization within correctional institutions. While the actual risk of sexual victimization remains low, the perception of rape among inmates is high. Given how one's fear can translate into behavior, understanding how institutions impact the culture surrounding prison rape highlights areas for reducing violence within prisons. The paper aims to discuss these issues. Design/methodology/approach This study includes secondary analysis of a quantitative database created from semi-structured interviews with 564 high security, general population inmates. Using fear of rape as the outcome of interest, bivariate and logistic regression analyses are used to comment on the impact of individual and facility level characteristics on this outcome. Findings In general, the results from this study suggest that the greatest risk factors for fearing rape while in prison are being male, having a mental health issue, and hearing about rape within the institution. From these specific findings a few general lessons can be learned with the hope that practitioners can translate these lessons into policy initiatives in order to combat fear of rape among our inmate population. Originality/value This paper aims to fill a gap in the research on how the facility contributes to the fear of rape within prison. The end goal is to inform policy makers so that suggestions can be made to combat this problem and prevent further misconduct within these facilities.

Expansion of mass-flowering crops leads to transient pollinator dilution and reduced wild plant pollination

2011-01-01

Agricultural land use results in direct biodiversity decline through loss of natural habitat, but may also cause indirect cross-habitat effects on conservation areas. We conducted three landscape-scale field studies on 67 sites to test the hypothesis that mass flowering of oilseed rape (Brassica napus) results in a transient dilution of bees in crop fields, and in increased competition between crop plants and grassland plants for pollinators. Abundances of bumble-bees, which are the main pollinators of the grassland plant Primula veris, but also pollinate oilseed rape (OSR), decreased with increasing amount of OSR. This landscape-scale dilution affected bumble-bee abundances strongly in OSR fields and marginally in grasslands, where bumble-bee abundances were generally low at the time of Primula flowering. Seed set of Primula veris, which flowers during OSR bloom, was reduced by 20 per cent when the amount of OSR within 1 km radius increased from 0 to 15 per cent. Hence, the current expansion of bee-attractive biofuel crops results in transient dilution of crop pollinators, which means an increased competition for pollinators between crops and wild plants. In conclusion, mass-flowering crops potentially threaten fitness of concurrently flowering wild plants in conservation areas, despite the fact that, in the long run, mass-flowering crops can enhance abundances of generalist pollinators and their pollination service.

Political rape as persecution: a legal perspective.

PubMed

Kelly, N

1997-01-01

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.

Does insecticide application in a winter oilseed rape field influence the abundance of pollen beetle Meligethes aeneus in nearby ornamental flowers and vegetables?

PubMed

2013-11-01

Pollen beetle is a pest that attacks oilseed rape as well as many other brassicaceous crops, garden vegetables and ornamental flowers. The present study was primarily carried out to investigate whether insecticide application in brassicaceous field crops might influence the abundance of pollen beetles in nearby private garden flowers and vegetables. At peak emergence of the new generation of pollen beetles, a significantly higher number of beetles were found in flowers, and in window traps, alongside untreated as opposed to alongside treated sections of the winter oilseed rape (WOSR) field. However, the type of flower played a role in the number of pollen beetles found in the flowers. The presence of pollen beetles in both ornamental and wild flowers was also significantly influenced by the direction of placement of the flowers. No pollen beetle, neither overwintering nor newly emerged, was observed in any of the brassicaceous vegetables placed along the field. The number of pollen beetles in the WOSR field strongly influenced the number of pollen beetles in nearby flowers of preference to the beetles, and insecticide treatment with Biscaya (thiacloprid) against pollen beetle in oilseed rape may thus help, indirectly, to protect nearby garden flowers from damage. © 2013 Society of Chemical Industry.

Various crops were tested in greenhouse and field trials for their potential utility in the rotation sequence in the potato cropping system in Meloidogyne chitwoodi-infested soils of the Klamath Basin in northeastern California and southern Oregon. Two Solarium accessions from the International Potato Center in Peru were potential sources of resistance to M. chitwoodi. Cultivars of barley, oat, rye, wheat, and white lupine were maintenance hosts, supporting the nematode population at its current level without substantial increase or decline. Poor to nonhosts to race 1 of the nematode included cultivars of alfalfa, amaranth, oilseed radish, oilseed rape, and safflower. These crops have potential for inclusion in the cropping system but are subject to various constraints, including frost sensitivity and availability of markets. Sugarbeet, a new crop in the area, is a maintenance or better host of M. chitwoodi. Potato, tomato, and sunflower are excellent hosts.

The oilseeds of the commercially important oilseed rape (Brassica napus) and turnip rape (Brassica rapa) were investigated with (1)H NMR metabolomics. The compositions of ripened (cultivated in field trials) and developing seeds (cultivated in controlled conditions) were compared in multivariate models using principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and orthogonal partial least squares discriminant analysis (OPLS-DA). Differences in the major lipids and the minor metabolites between the two species were found. A higher content of polyunsaturated fatty acids and sucrose were observed in turnip rape, while the overall oil content and sinapine levels were higher in oilseed rape. The genotype traits were negligible compared to the effect of the growing site and concomitant conditions on the oilseed metabolome. This study demonstrates the applicability of NMR-based analysis in determining the species, geographical origin, developmental stage, and quality of oilseed Brassicas. Copyright © 2014 Elsevier Ltd.

Rape straw in Leshan area are rape stalks, including stems, leaves and pods after removing rapeseed. Leshan area is one of the main rape planting areas in Sichuan Province and rape planting area is large. Each year will produce a lot of rape straw. Based on the analysis of the trend of rapeseed planting area and rapeseed yield from 2008 to 2014, the change trend of rape straw resources in Leshan from 2008 to 2014 was analyzed and the decision-making reference was provided for resource utilization of rape straw. The results showed that the amount of rape straw resources in Leshan was very large, which was more than 100,000 tons per year, which was increasing year by year. By 2014, the amount of rape straw resources in Leshan was close to 200,000 tons.

Dealing with rape in a new political landscape.

PubMed

Stern, Baroness Vivien

2012-01-01

Rape is controversial and constructing rape policy is complicated. Most victims, men and women, are raped by someone they know. The court case usually hangs on whether or not the complainant consented to the act. The defence feels free to portray the complainant in a negative light making the trial an ordeal. Some complainants decide it is one ordeal too many and withdraw from the process. Sustained criticism of the handling of rape cases over many years led to substantial improvements, with specially trained police officers, prosecutors and judges, and more defendants being convicted. Yet providing justice to rape victims requires more than an effective criminal justice response. It also requires recognition that victims are entitled to the support of the state. They should be treated with respect regardless of whether the case goes to trial or not. The rate of convictions for rape is not the only, or even the most important measure of a good policy.

Metacognitive aspects of rape myths: subjective strength of rape myth acceptance moderates its effects on information processing and behavioral intentions.

PubMed

Süssenbach, Philipp; Eyssel, Friederike; Bohner, Gerd

2013-07-01

The authors present a metacognitive approach to influences of rape myth acceptance (RMA) on the processing of rape-related information and rape proclivity. In Study 1, participants (N = 264) completed an RMA scale and subsequently reported the subjective strength (e.g., importance, certainty) of their RMA. Then they read about a rape case, viewed a photograph of the alleged crime scene, and rated the defendant's guilt on several items. Depending on condition, the photograph contained either RMA-applicable stimuli (e.g., alcoholic beverages) or neutral stimuli. Higher RMA predicted lower ratings of defendant guilt especially when applicable stimuli were present and RMA was strong. Study 2 (N = 85) showed that RMA-related attitude strength also moderated the effect of RMA on self-reported rape proclivity. Results of both studies indicate that the subjective strength of rape-related beliefs may be reliably assessed and serves as an important moderator of effects of RMA. The implications of these findings for prevention programs as well as future directions for research are discussed.

Attitudes toward wife rape: effects of social background and victim status.

PubMed

Basile, Kathleen C

2002-06-01

The current literature on wife rape is minimal compared to the published research in areas such as wife battering or date rape, and most of the existent work on attitudes toward wife rape is dated and/or focuses on limited samples (i.e., college populations). Using data from a nationally representative telephone survey, this study examined national attitudes toward wife rape using the following measures: perceptions of the occurrence of wife rape, perceptions of the frequency of wife rape, and perceptions of three rape scenarios. Respondent sex, education, age, race, and female victim status were predictors. Findings reveal that older, non-white respondents were less likely to believe wife rape occurs. Males and the more educated were less likely to believe it occurs frequently. Older and less educated respondents were less likely to believe forced sex scenarios between a husband and wife constitute wife rape. Among women, non-victims of forced sex were significantly less likely than current victims to believe that wife rape occurs.

The present study was designed to assess homing behavior of bees foraging on winter oilseed rape grown from seed treated with thiamethoxam (as Cruiser OSR), with 1 field drilled with thiamethoxam-treated seed and 2 control fields drilled with fungicide-only-treated seed. Twelve honeybee colonies were used per treatment group, 4 each located at the field edge (on-field site), at approximately 500 m and 1000 m from the field. A total of nearly 300 newly emerged bees per colony were fitted (tagged) with Mic3 radio frequency identification (RFID) transponders and introduced into each of the 36 study hives. The RFID readers fitted to the entrances of the test colonies were used to monitor the activity of the tagged bees for the duration of the 5-wk flowering period of the crop. These activity data were analyzed to assess any impact on flight activity of bees foraging on the treated compared with untreated crops. Honeybees were seen to be actively foraging within all 3 treatment groups during the exposure period. The data for the more than 3000 RFID-tagged bees and more than 90 000 foraging flights monitored throughout the exposure phase for the study follow the same trends across the treatment and controls and at each of the 3 apiary distances, indicating that there were no effects from foraging on the treated crop. Under the experimental conditions, there was no effect of foraging on thiamethoxam-treated oilseed rape on honeybee flight activity or on their ability to return to the hive. © 2015 SETAC.

An acute post-rape intervention to prevent substance use and abuse.

PubMed

Acierno, Ron; Resnick, Heidi S; Flood, Amanda; Holmes, Melisa

2003-12-01

The trauma of rape is routinely associated with extreme acute distress. Such peri-event anxiety increases risk of developing psychopathology and substance use or abuse post-rape, with the degree of initial distress positively predicting future problems. Unfortunately, the nature of post-rape forensic evidence collection procedures may exacerbate initial distress, thereby potentiating post-rape negative emotional sequelae. Consequently, substance use may increase in an effort to ameliorate this distress. To address this, a two-part video intervention was developed for use in acute post-rape time frames to (a) minimize anxiety during forensic rape examinations, thereby reducing risk of future emotional problems, and (b) prevent increased post-rape substance use and abuse. Pilot study data with 124 rape victims indicated that the low-cost, easily administered intervention was effective in reducing risk of marijuana abuse at 6 weeks. Nonstatistically significant trends also were evident for reduced marijuana use. Trends were also noted in favor of the intervention in the subgroup of women who were actively using substances pre-rape (among pre-rape alcohol users, 28% viewers vs. 43% nonviewers met criteria for post-rape alcohol abuse; among pre-rape marijuana users, the rates of post-marijuana use were 17% vs. 43%).

Contribution of insect pollinators to crop yield and quality varies with agricultural intensification

Background. Up to 75% of crop species benefit at least to some degree from animal pollination for fruit or seed set and yield. However, basic information on the level of pollinator dependence and pollinator contribution to yield is lacking for many crops. Even less is known about how insect pollination affects crop quality. Given that habitat loss and agricultural intensification are known to decrease pollinator richness and abundance, there is a need to assess the consequences for different components of crop production. Methods. We used pollination exclusion on flowers or inflorescences on a whole plant basis to assess the contribution of insect pollination to crop yield and quality in four flowering crops (spring oilseed rape, field bean, strawberry, and buckwheat) located in four regions of Europe. For each crop, we recorded abundance and species richness of flower visiting insects in ten fields located along a gradient from simple to heterogeneous landscapes. Results. Insect pollination enhanced average crop yield between 18 and 71% depending on the crop. Yield quality was also enhanced in most crops. For instance, oilseed rape had higher oil and lower chlorophyll contents when adequately pollinated, the proportion of empty seeds decreased in buckwheat, and strawberries’ commercial grade improved; however, we did not find higher nitrogen content in open pollinated field beans. Complex landscapes had a higher overall species richness of wild pollinators across crops, but visitation rates were only higher in complex landscapes for some crops. On the contrary, the overall yield was consistently enhanced by higher visitation rates, but not by higher pollinator richness. Discussion. For the four crops in this study, there is clear benefit delivered by pollinators on yield quantity and/or quality, but it is not maximized under current agricultural intensification. Honeybees, the most abundant pollinator, might partially compensate the loss of wild pollinators in

To describe some characteristics of rape in Mexico City. Descriptive study of rape victims who attended a specialized institution between 1990 and 1996. A support psychotherapist applied a semistructured questionnaire on the victims characteristics, the aggressor and the circumstances of the rape. A total of 531 victims were studied, 85.8% were females, almost half were minors and the median of scholarity was nine years. All aggressors were males, 62% were known to the victim, 86.7% were relatives or near to the family. Aggression occurred at the home of the victim or aggressor in 55.4% of the cases, 49.2% of the cases occurred in 4 of the 16 City districts. In the studied population, women were the gender with greatest risk of being raped, except in the 5 to 14 year old group in which boys were in greater risk. Unemployed and underpaid men were the most frequent aggressors. There is a greater risk of being raped by a member of the family, couple or friend than by a stranger, and in the victim's or the aggressor's home more than anywhere else. Findings point to the necessity of establishing preventive programs and providing specialized attention to victims and aggressors.

Ramsay, S

1999-12-11

This article documents the turning points in the rape issue, which led to the acknowledgement of its prevalence in the world, especially in South Africa. November 25 marked the first day of the "Take a Stand" movement in South Africa, which coincided with the International Day Against Violence Against Women. This movement involves peaceful protests and poster campaigns, followed by months of sustained news coverage of rape. This was launched by a coalition of organizations, including women's groups, churches, businesses, and trades unions, that are speaking out against all forms of sexual violence. In the international community, rape is starting to be taken seriously. In 1996, sexual assault was cited as a crime against humanity by the International Criminal Tribunal for the former Yugoslavia. In addition, a forum in London, UK, on November 25, discussed rape issues and recommendations on how to prevent such violence were given. The need for a change in legal systems, which currently discourage women from taking legal actions, was also recognized. In view of this, the medical community is challenged to provide sensitive and appropriate help to women who have been assaulted.

Background It is important for rape victims to receive medical care to prevent and treat rape-related diseases and injuries, access forensic exams, and connect to needed resources. Few victims seek care, and factors associated with post-rape medical care–seeking are poorly understood. Purpose The current study examined prevalence and factors associated with post-rape medical care–seeking in a national sample of women who reported a most-recent or only incident of forcible rape, and drug- or alcohol-facilitated/incapacitated rape when they were aged ≥14 years. Methods A national sample of U.S. adult women (N=3001) completed structured telephone interviews in 2006, and data for this study were analyzed in 2011. Logistic regression analyses examined demographic variables, health, rape characteristics, and post-rape concerns in relation to post-rape medical care–seeking among 445 female rape victims. Results A minority of rape victims (21%) sought post-rape medical attention following the incident. In the final multivariate model, correlates of medical care included black race, rape-related injury, concerns about sexually transmitted diseases, pregnancy concerns, and reporting the incident to police. Conclusions Women who experience rapes consistent with stereotypic scenarios, acknowledge the rape, report the rape, and harbor health concerns appear to be more likely to seek post-rape medical services. Education is needed to increase rape acknowledgment, awareness of post-rape services that do not require formal reporting, and recognition of the need to treat rape-related health problems.

1996-01-01

The significance of double crop (intercrop and sequential crop), single crop (rainy season crop fallow from June to September), and rotations on densities of Heterodera cajani, Helicotylenchus retusus, and Rotylenchulus reniformis was studied on Vertisol (Typic Pellusterts) between 1987 and 1993. Cowpea (Vigna sinensis), mungbean (Phaseolus aureus), and pigeonpea (Cajanus cajan) greatly increased the population densities of H. cajani and suppressed the population densities of other plant-parasitic nematodes. Mean population densities of H. cajani were about 8 times lower in single crop systems than in double crop systems, with pigeonpea as a component intercrop. Plots planted to sorghum, safflower, and chickpea in the preceding year contained fewer H. cajani eggs and juveniles than did plots previously planted to pigeonpea, cowpea, or mungbean. Continuous cropping of sorghum in the rainy season and safflower in the post-rainy season markedly reduced the population density of H. cajani. Sorghum, safflower, and chickpea favored increased population densities of H. retusus. Adding cowpea to the system resulted in a significant increase in the densities of R. reniformis. Mean densities of total plant-parasitic nematodes were three times greater in double crop systems, with pigeonpea as a component intercrop than in single crop systems with rainy season fallow component. Cropping systems had a regulatory effect on the nematode populations and could be an effective nematode management tactic. Intercropping of sorghum with H. cajani tolerant pigeonpea could be effective in increasing the productivity of traditional production systems in H. cajani infested regions. PMID:19277141

Male Peer Support to Hostile Sexist Attitudes Influences Rape Proclivity.

PubMed

Durán, Mercedes; Megías, Jesús L; Moya, Miguel

2018-07-01

Sexual assault affects a large proportion of women in the world. Although most rapes are committed by one man, the act itself may be influenced by many (e.g., the peer group). Hostile sexism (HS) has repeatedly been associated with men's rape proclivity, but the influence exerted by the HS of the peer group on rape proclivity has not been investigated. In this study, we explored the impact of perceived male peer support to HS on participants' rape proclivity. A sample of Spanish undergraduate students from a university in the south of Spain ( N = 134) completed the Ambivalent Sexism Inventory. Immediately afterwards, they received feedback on the supposed sexist responses of a peer group (high vs. low in HS); we kept the benevolent sexism (BS) of the peer group at medium levels. Next, we assessed participants' rape proclivity using acquaintance rape scenarios. Results showed an interaction between participants' own levels of HS and information about the HS of the peer group. Men high in HS reported higher rape proclivity in the high-HS peer-group condition than in the low-HS peer-group condition. By contrast, information on the peer group did not affect self-reported rape proclivity of men low in HS. Results also corroborated the relationship between participants' levels of HS and rape proclivity, and expanded the literature by revealing an unexpected influence of participants' BS on rape proclivity.

Stop blaming the victim: a meta-analysis on rape myths.

PubMed

Suarez, Eliana; Gadalla, Tahany M

2010-11-01

Although male rape is being reported more often than before, the majority of rape victims continue to be women. Rape myths-false beliefs used mainly to shift the blame of rape from perpetrators to victims-are also prevalent in today's society and in many ways contribute toward the pervasiveness of rape. Despite this, there has been limited consideration as to how rape prevention programs and policies can address this phenomenon, and there is no updated information on the demographic, attitudinal, or behavioral factors currently associated with rape myths. This research aimed to address this gap by examining the correlates of rape-myths acceptance (RMA) in published studies. A total of 37 studies were reviewed, and their results were combined using meta-analytic techniques. Overall, the findings indicated that men displayed a significantly higher endorsement of RMA than women. RMA was also strongly associated with hostile attitudes and behaviors toward women, thus supporting feminist premise that sexism perpetuates RMA. RMA was also found to be correlated with other "isms," such as racism, heterosexism, classism, and ageism. These findings suggest that rape prevention programs and policies must be broadened to incorporate strategies that also address other oppressive beliefs concurrent with RMA. Indeed, a renewed awareness of how RMA shapes societal perceptions of rape victims, including perceptions of service providers, could also reduce victims' re-victimization and enhance their coping mechanisms.

Risk Factors for PTSD and Depression in Female Survivors of Rape

Objective To investigate association of the socio-demographic factors, characteristics of rape and social support to the development of depression and post-traumatic stress disorder at six months after the rape. Methods A cross-sectional survey with female survivors of rape was carried out in three provinces of South Africa six months after the rape. Results One hundred female survivors s of sexual assault were interviewed. More than half (53%) were from Limpopo, (25%) from Western Cape and (22%) from KwaZulu -Natal. 87% reported high levels of PTSD and (51%) moderate to severe depression post-rape. The major risk factors for PTSD and depression were the unmarried survivors of rape and those living in KZN. The female survivors of rape in KZN province were seven times more likely to experience symptoms of depression compared to other provinces, while married/cohabiting female rape survivors were six times less likely to report symptoms of depression compared to the unmarried female rape survivors. Conclusion These findings add support to existing literature on PTSD and depression as common mental health consequence of rape and also provide evidence that survivors’ socio- demographics – marital status, employment status are significant contributors to the development of symptoms of depression and PTSD after rape. The results have research and clinical practice relevance for ensuring that PTSD and trauma treatment focuses on an in-depth understanding of the various aspects of the socio demographic factors and rape characteristics that contribute to survivors’ mental state and how these compound stress and depression symptoms over time post-rape victimization.

A Protection Motivation Theory application to date rape education.

PubMed

Singh, Shweta; Orwat, John; Grossman, Susan

2011-12-01

Date rape risk communication is a key component of education-based Date Rape Prevention Programs, common across colleges. In such programs, risk assessment in date rape is approached cautiously in order to avoid a tone of "victim blaming." Since it is important in the assessment of any risk to understand the surrounding social context of the risky situation and the individual's unique relationship with that social context, this study examines Protection Motivation Theory as it applies to handling the risk of date rape without victim blaming. The paper links individual personality and social contexts with risk communication. The study sample comprised 367 undergraduate women enrolled in a large Southern Public University. The study examines the relationships between dating activity, social competency, and type of information provided with the dependents variables of date rape related protection behavior (intent), belief, and knowledge. A factorial multiple analysis of covariance analysis found that the dependent variables had a significant relationship with aspects of social competency and dating activity. The exposure to varying information about date rape was not significantly related to the dependent variables of date rape-related protection behavior (intent), belief, and knowledge. The identification of social competency and dating activity status as protective factors in this study makes a significant contribution to the practice and research efforts in date rape education.

Seed size has significant implications in ecology, because of its effects on plant fitness. The hybrid seeds that result from crosses between crops and their wild relatives are often small, and the consequences of this have been poorly investigated. Here we report on plant performance of hybrid and its parental transgenic oilseed rape (Brassica napus) and wild B. juncea, all grown from seeds sorted into three seed-size categories. Three seed-size categories were sorted by seed diameter for transgenic B. napus, wild B. juncea and their transgenic and non-transgenic hybrids. The seeds were sown in a field at various plant densities. Globally, small-seeded plants had delayed flowering, lower biomass, fewer flowers and seeds, and a lower thousand-seed weight. The seed-size effect varied among plant types but was not affected by plant density. There was no negative effect of seed size in hybrids, but it was correlated with reduced growth for both parents. Our results imply that the risk of further gene flow would probably not be mitigated by the small size of transgenic hybrid seeds. No fitness cost was detected to be associated with the Bt-transgene in this study.

Teets, J M

1997-01-01

This descriptive study investigated the incidence and experience of rape among chemically dependent women. Sixty women in a residential treatment facility were interviewed about sexual trauma they had experienced in their lives. In this sample 73% had been raped, and 45% had been raped more than once. The stories of rape were classified in five categories: rape while in the context of using, when too high to resist, while prostituting, by a significant other, and by a family member. Some 35% of the rapist described were friends of the women with whom they were using drugs. Only 20% of the rapes were reported to the police. Clinical implications for treatment of addicted women who are also survivors of violence is discussed.

The costs of rape.

The current study examined costs experienced by victims of completed rape (n=49) and attempted sexual assault (n=91) using quantitative analyses of 13 domains: health, self-esteem, self-perceived attractiveness, self-perceived mate value, family relationships,work life, social life, social reputation, sexual reputation, desire to have sex, frequency of sex, enjoyment of sex, and long-term, committed relationships. Women also provided descriptive accounts of their experiences, and we used these to illustrate the costs in the victims' own words.Compared to victims of an attempted sexual assault, victims of a completed rape reported significantly more negative outcomes in 11 of the 13 domains. The most negatively affected domains were self-esteem, sexual reputation, frequency of sex, desire to have sex, and self-perceived mate value. Although victims of rape experienced more negative effects than victims of attempted sexual assault,both groups of victims reported negative effects in every domain.Discussion focuses on the implications of the differing degrees and patterns of the costs of attempted and completed sexual victimization.

Biological subsoil management: new insights into processes of structure building and implications for crop growth

Athmann, Miriam; Kautz, Timo; Köpke, Ulrich

2017-04-01

Large sized continuous biopores (diameter > 2 mm) in arable subsoils can contribute to enhance soil aeration, increase water infiltration, reduce water runoff and serve as preferential pathways for root growth. Biopores can be generated by taproots, but these pores probably have limited physical stability unless they are colonized by anecic earthworms and coated with worm cast. Long-term field experiments have shown that populations of anecic earthworms and numbers of biopores are promoted by perennial fodder cropping, no-till cropping and reduced tillage systems, i.e. extended soil rest. Potential effects of biopores on root growth of annual crops include accelerating access to deep soil layers, facilitating exploitation of water while simultaneously allowing nutrient acquisition from the pore wall and the bulk soil. Biopores can be considered as hot spots for nutrient acquisition of crops, especially when the pore wall is enriched in nutrients as a consequence of deposition of decaying plant material and feces of earthworms. However, the extent of such effects largely depends on physical properties of the bulk soil. Preferential root growth through biopores has been observed in many types of subsoil. The role of biopores is expected to be relevant especially when rooting in the bulk soil is impeded by high penetration resistance. Nevertheless, in hard-setting clay soils clumping of roots has been reported, when roots were unable to re-enter the bulk soil from biopores' lumen. Recent field experiments on a deep loamy Haplic Luvisol indicated increased biopore density in the subsoil promoting root growth of winter cereals and winter oilseed rape not necessarily resulting in significant effects on shoot parameters. Nevertheless, in a dry year increased biopore density had beneficial effects on N uptake, root and shoot growth and grain yield of spring crops.

The cultivation of Pleurotus ostreatus with rape straw not only can save the cultivation cost of P. ostreatus, but also can reuse the resources and protect the environment. By adding different proportion of rape straw to the cultivation material of P. ostreatus, the reasonable amount of rape straw was selected and the economic benefit of P. ostreatus cultivated with the optimum amount of rape straw was analyzed. The results showed that adding 10% to 40% rape straw to the cultivation material of P. ostreatus did not affect the yield and biological conversion rate of P. ostreatus, and the ratio of production and investment of the amount of rape straw in the range of 10% to 50% was higher than of cottonseed husk alone as the main material of the formula.

2017-02-01

In a double cropping rice field experiment, effects of five winter cover crops on the total organic carbon (TOC), active organic carbon (AOC), carbon pool management index (CPMI) and organic carbon storage were studied in three soil layers (0-5, 5-10 and 10-20 cm).Winter cover crops of ryegrass (Ry), Chinese milk vetch (Mv), potato (Po), and rape (Ra) between two rice crops were compared with fallow as control (CK). The results showed that the TOC and AOC contents under Ry, Mv, Po and Ra treatments were higher than those of CK in all three la-yers. Meanwhile, the TOC and AOC contents in Po treatment were higher than those of other treatments. Compared with CK, the AOC, activity index (AI), carbon pool index (CPI) and CPMI in the soil were improved through the recycling of winter cover crops straw. The AOC, AI, CPI and CPMI in the studied layers increased in order of Po>Mv>Ry>Ra>CK. The results indicated that the recycling of winter cover crops straw promoted the storage of SOC in the 0-20 cm soil profile as compared with CK. The strongest effect of the winter cover crops on the SOC storage occurred in Mv treatment, followed by Mv and Po treatments, and the SOC storage increased with the increasing soil depth.

Giving birth with rape in one's past: a qualitative study.

2013-09-01

Rape is one of the most traumatizing violations a woman can be subjected to, and leads to extensive health problems, predominantly psychological ones. A large proportion of women develop a form of posttraumatic stress termed Rape Trauma Syndrome. A previous study by our research group has shown that women with a history of rape far more often had an operative delivery in their first birth and those who gave birth vaginally had second stages twice as long as women with no history of sexual assault. The aim of this study is to examine and illuminate how women previously subjected to rape experience giving birth for the first time and their advice on the kind of birth care they regard as good for women with a history of rape. A semi-structured interview with 10 women, who had been exposed to rape before their first childbirth. Data on the birth experience were analyzed by qualitative content analysis. The main theme was "being back in the rape" with two categories: "reactivation of the rape during labor," with subcategories "struggle," "surrender," and "escape" and "re-traumatization after birth," with the subcategories "objectified," "dirtied," and "alienated body." A rape trauma can be reactivated during the first childbirth regardless of mode of delivery. After birth, the women found themselves re-traumatized with the feeling of being dirtied, alienated, and reduced to just a body that another body is to come out of. Birth attendants should acknowledge that the common measures and procedures used during normal birth or cesarean section can contribute to a reactivation of the rape trauma. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

An Empirical Exploration Into the Measurement of Rape Culture.

PubMed

Johnson, Nicole L; Johnson, Dawn M

2017-09-01

Feminist scholars have long argued the presence of a "rape culture" within the United States; however, limited efforts have been made to quantify this construct. A model of rape culture was first proposed in 1980 and expanded in the 1990s in an effort to quantify rape myth acceptance. This model posits that five underlying components make up a rape culture: traditional gender roles, sexism, adversarial sexual beliefs, hostility toward women, and acceptance of violence. Although these components are proposed as cultural phenomenon and thus distinct from individually held beliefs, they have been exclusively explored on an individual level. Thus, to promote exploration of this phenomenon beyond individually held beliefs, the authors adapted a series of well-established measures to assess the perceived peer support of the constructs proposed to underlie rape culture and assess initial reliability and validity in a sample of 314 college students. Following determination of reliability and validity of these adapted measures, a hierarchical confirmatory factor analysis was run to examine the proposed model of rape culture. Results of this study highlight the uniqueness between individual and cultural factors as several items did not translate from an individual (i.e., personal endorsement) to a cultural level (i.e., perceived peer support) and were subsequently removed from the proposed final measurements. Furthermore, initial support for the aforementioned model of rape culture was identified. These findings are crucial given that limited conclusions may be drawn about the existence and in turn eradication of rape culture without an agreed upon definition and source of measurement.

The incorporation of various types of crop straw to agricultural soils has long been practiced to improve soil fertility. However, the effects of crop straw on the fate of organo-chlorine pesticides in flooded paddy soils are not well understood. The dechlorination of pentachlorophenol (PCP) in four vertical profiles (0-10, 10-20, 20-30, 30-50 mm depth) of two flooded paddy soils, a Plinthudult (Soil 1) and a Tropudult (Soil 2) was investigated following the application of four crop straws (rice, wheat, rape and Chinese milk vetch) to them. In all treatments, PCP dechlorination decreased with increasing soil depth. In the crop straw treatments, PCP was almost completely dechlorinated within 60 days, and rapidly transformed to 2,3,4,5-tetrachlorophenol, and further to 3,4,5-trichlorophenol. Further dechlorination of 3,4,5-trichlorophenol also occurred in all treatments except for the rape straw. It is possible that the NH 4 + and NO 3 - derived from the straw are responsible for the inhibition of the 3,4,5-trichlorophenol dechlorination. The reduction of Fe (III) and SO 4 2- increased following application of the crop straws. The RDA analysis indicated that the Fe (III) reducing bacteria might be involved in the ortho-dechlorination, while SO 4 2- reducing bacteria were involved in para- and meta-dechlorination of PCP. The complete detoxification of PCP depended upon both the crop straw type and soil properties. Copyright © 2017 Elsevier Ltd. All rights reserved.

Whether treatment programs are effective at rehabilitating rapists is yet to be determined empirically. From a scientist-practitioner perspective, treatment should be based on an empirical understanding of rape and rapists, and evidence-based knowledge of treatment outcome with rapists. In this paper we comprehensively review the characteristics of rapists, etiological features implicated in the commission of rape, and relevant treatment outcome research. We pay particular attention to contemporary knowledge about the core vulnerabilities and features required to understand and treat rapists effectively, and, where possible, highlight similarities and differences between rapists, child molesters and non-sexual violent offenders. We use an epistemological framework to (a) critique the various etiological accounts of rape available and (b) help guide professionals' use of such knowledge in both treatment design and evaluation. Gaps in the understanding of rapists' characteristics and etiological features are highlighted, as are discrepancies between current knowledge and treatment approaches. We conclude by highlighting areas for future research and practice innovation.

Evaluation of an intervention to change attitudes toward date rape.

The prevalence of date rape among college students is a major concern. Although much research has been done on risk factors for date rape, few researchers have specifically described interventions for the various stages of developing a date-rape prevention program. Previous programs have often relied on educational videos that feature a "typical" date-rape scenario, a format that some researchers suggest may have a negative effect on the way people engage in aggressive sexual behavior. A less violent theatrical production based on social learning theory and risk-factor reduction that resulted in a significant improvement in attitudes related to date rape among both male and female students at an elite Texas university is described.

Use of field reflectance data for crop mapping using airborne hyperspectral image

NASA Astrophysics Data System (ADS)

Nidamanuri, Rama Rao; Zbell, Bernd

2011-09-01

Recent developments in hyperspectral remote sensing technologies enable acquisition of image with high spectral resolution, which is typical to the laboratory or in situ reflectance measurements. There has been an increasing interest in the utilization of in situ reference reflectance spectra for rapid and repeated mapping of various surface features. Here we examined the prospect of classifying airborne hyperspectral image using field reflectance spectra as the training data for crop mapping. Canopy level field reflectance measurements of some important agricultural crops, i.e. alfalfa, winter barley, winter rape, winter rye, and winter wheat collected during four consecutive growing seasons are used for the classification of a HyMAP image acquired for a separate location by (1) mixture tuned matched filtering (MTMF), (2) spectral feature fitting (SFF), and (3) spectral angle mapper (SAM) methods. In order to answer a general research question "what is the prospect of using independent reference reflectance spectra for image classification", while focussing on the crop classification, the results indicate distinct aspects. On the one hand, field reflectance spectra of winter rape and alfalfa demonstrate excellent crop discrimination and spectral matching with the image across the growing seasons. On the other hand, significant spectral confusion detected among the winter barley, winter rye, and winter wheat rule out the possibility of existence of a meaningful spectral matching between field reflectance spectra and image. While supporting the current notion of "non-existence of characteristic reflectance spectral signatures for vegetation", results indicate that there exist some crops whose spectral signatures are similar to characteristic spectral signatures with possibility of using them in image classification.

Understanding Disparities in Service Seeking Following Forcible Versus Drug-or Alcohol-Facilitated/ Incapacitated Rape

Victims of drug- or alcohol-facilitated/incapacitated rape (DAFR/IR) are substantially less likely to seek medical, rape crisis, or police services compared with victims of forcible rape (FR); however, reasons for these disparities are poorly understood. The current study examined explanatory mechanisms in the pathway from rape type (FR vs. DAFR/IR) to disparities in post-rape service seeking (medical, rape crisis, criminal justice). Participants were 445 adult women from a nationally representative household probability sample who had experienced FR, DAFR/IR, or both since age 14. Personal characteristics (age, race, income, prior rape history), rape characteristics (fear, injury, loss of consciousness), and post-rape acknowledgment, medical concerns, and service seeking were collected. An indirect effects model using bootstrapped standard errors was estimated to examine pathways from rape type to service seeking. DAFR/IR-only victims were less likely to seek services compared with FR victims despite similar post-rape medical concerns. FR victims were more likely to report fear during the rape and a prior rape history, and to acknowledge the incident as rape; each of these characteristics was positively associated with service seeking. However, only prior rape history and acknowledgment served as indirect paths to service seeking; acknowledgment was the strongest predictor of service seeking. Diminished acknowledgment of the incident as rape may be especially important to explaining why DAFR/IR victims are less likely than FR victims to seek services. Public service campaigns designed to increase awareness of rape definitions, particularly around DAFR/IR, are important to reducing disparities in rape-related service seeking. PMID:25846758

Although patients with factitious disorders typically seek the "patient" role through illness portrayals, some instead portray themselves falsely as "victims." We discuss the cases of four women who claimed to have been victims of rape; the allegations ultimately were disproved. Factitious rape may be prompted by a search for nurturance; by dissociation, leading individuals to believe that trauma earlier in life is ongoing; by a need to be rescued from real, current abuse; and by projection of anger onto specific male targets. Although dramatic, factitious rape is rare, we advocate thorough investigation of rape claims even when patients have known histories of deceptive behavior.

Police officers' collaboration with rape victim advocates: barriers and facilitators.

PubMed

Rich, Karen; Seffrin, Patrick

2013-01-01

Secondary victimization may occur when rape victims make police reports. This can compromise the quality of official statements and jeopardize criminal cases. Rape reporters receive better treatment by police officers when advocates are involved and best practice police work includes such collaboration. Studies of advocates have described tension, role confusion, and poor communication with police officers. Many variables, including rape myth acceptance (RMA) and training on sexual assault dynamics, may affect officers' collaboration with advocates. There were 429 police officers who responded to a survey measuring their victim interviewing skill, formal training about rape, years on the job, number of victims known personally, number of recent rape cases, RMA, and collaboration with advocates. Results suggest that officers' interviewing skill, years on the job, and specific training are related to collaboration with victim advocates on rape cases. Professional, rather than personal, variables were most predictive of collaboration. Implications for officer selection and training are explored.

The purpose of this article is to explore whether gender-blind sexism, as an extension of Bonilla-Silva's racialized social system theory, is an appropriate theoretical framework for understanding the creation and continued prevalence of rape myth acceptance. Specifically, we hypothesize that individuals who hold attitudes consistent with the frames of gender-blind sexism are more likely to accept common rape myths. Data for this article come from an online survey administered to the entire undergraduate student body at a large Midwestern institution (N = 1,401). Regression analysis showed strong support for the effects of gender-blind sexism on rape myth acceptance. © The Author(s) 2016.

Impact of shortened crop rotation of oilseed rape on soil and rhizosphere microbial diversity in relation to yield decline.

2013-01-01

Oilseed rape (OSR) grown in monoculture shows a decline in yield relative to virgin OSR of up to 25%, but the mechanisms responsible are unknown. A long term field experiment of OSR grown in a range of rotations with wheat was used to determine whether shifts in fungal and bacterial populations of the rhizosphere and bulk soil were associated with the development of OSR yield decline. The communities of fungi and bacteria in the rhizosphere and bulk soil from the field experiment were profiled using terminal restriction fragment length polymorphism (TRFLP) and sequencing of cloned internal transcribed spacer regions and 16S rRNA genes, respectively. OSR cropping frequency had no effect on rhizosphere bacterial communities. However, the rhizosphere fungal communities from continuously grown OSR were significantly different to those from other rotations. This was due primarily to an increase in abundance of two fungi which showed 100% and 95% DNA identity to the plant pathogens Olpidium brassicae and Pyrenochaeta lycopersici, respectively. Real-time PCR confirmed that there was significantly more of these fungi in the continuously grown OSR than the other rotations. These two fungi were isolated from the field and used to inoculate OSR and Brassica oleracea grown under controlled conditions in a glasshouse to determine their effect on yield. At high doses, Olpidium brassicae reduced top growth and root biomass in seedlings and reduced branching and subsequent pod and seed production. Pyrenochaeta sp. formed lesions on the roots of seedlings, and at high doses delayed flowering and had a negative impact on seed quantity and quality.

Unacknowledged Rape: The Influences of Child Sexual Abuse and Personality Traits.

PubMed

Wilson, Laura C; Scarpa, Angela

2015-01-01

Evidence supports that the majority of young women who experience sexual victimization that meets the legal definition of rape do not label their experiences as rape--this has been termed unacknowledged rape. In a sample of 77 young adult women, the odds of unacknowledged rape significantly increased as a function of less severe child sexual abuse histories and greater levels of dysfunctional personality traits. Potential explanations for these findings as well as clinical implications are discussed. Because of the potential psychological and societal consequences of unacknowledged rape, it is vital that researchers continue to examine this phenomenon.

The right to protection from sexual assault: the Indian anti-rape campaign.

PubMed

Gangoli, G

1996-11-01

This article reveals a viewpoint that emphasizes some dilemmas among Indian feminist practice, women's sexuality in legal terms, and case law in India. The Indian Women's Movement (IWM) was successful in 1983 in adding a legal amendment on rape and child abuse. The case that mobilized women to change the law occurred in 1980 when a court acquitted two policemen who were charged with raping and molesting a 16-year-old tribal girl. The Bombay High Court overturned the judgement and convicted both policemen. The case was appealed, and the policemen successfully argued that rape did not occur because the girl did not protest and was sexually experienced anyway. In 1980 the Forum Against Rape was formed to mobilize public support and to lobby the State for reform of the law on rape. The campaign focused on custodial rape and political repression, rape as civil rights issue, and rape as a women's issue. There was a distancing between the victim, who occupied a lower caste and class position, and her defenders in the women's groups. The campaign appealed to both the appropriate judgement of the State and the denial that the State was an effective vehicle for change. The campaign did not directly address incest and marital rape or domestic violence within families. The legislature debated the issue of legal change during 1982. The debate revealed deep divisions about sexuality and women's status. It was argued that chaste women were not rape victims, and unchaste women were of a socially inferior caste and class. It was argued that there should be a ban on child marriage rather than spousal rape laws. Child rape is a legal issue only when the perpetrator is outside the family. Rape was discussed as an act of lust and not violence. In 1992, a woman promoting an end to child marriage was raped and the men were acquitted. It was argued that the law was out-of-date and in need of revision.

Rape in South Africa: an invisible part of apartheid's legacy.

PubMed

Armstrong, S

1994-06-01

Male dominated power systems in South Africa coupled with a culture of aggression and domination have not allowed for the mainstream emergence of qualities such as trust, compassion, and gentleness, frequently associated with female virtues. Rape under such circumstances is the assertion of male power, and, as expected, the numbers of rape cases and other forms of gender violence have increased. Under an apartheid system, where only the rape of white women was prosecuted, and gender and race issues could diffuse the black struggle, there were difficulties in mobilizing support to end violence against black women. There was social acceptance that rape of black women was part of life. Police statistics on the incidence of rape were notoriously unreliable, because only a small percentage of cases are reported to police, and many women would be ashamed to admit to marital abuse, including rape. In women's groups, it was reported that 1 out of every 4 women had been raped, and raped at early ages, such as 14 years of age. In impoverished communities, there is widespread poverty, injustice, prejudice, alcohol abuse, and other conditions impacting on women. The rapists may be school classmates, or street fighters, or political activists. The sexual initiation of women worldwide and in South Africa frequently is accompanied by coercion. Abduction and forced sex is considered legitimate for young men, who believe that mental health is deleteriously affected by lack of sex. Girls may even be abducted from the classroom, as a way of preventing women's power and control over assets and resources and diminishing the potential threat to gender power relations. School girls who become pregnant are often forced to leave school. Victims of rape may be excluded from family life and forced to seek prostitution as a means of support. Rape is reportedly experienced among older women with bottles, tins, or other devices which inflict injury. Only rape with penal penetration is an

An empirical study of rape in the context of multiple murder.

PubMed

DeLisi, Matt

2014-03-01

In recent years, multiple homicide offending has received increased research attention from criminologists; however, there is mixed evidence about the role of rape toward the perpetration of multiple murder. Drawing on criminal career data from a nonprobability sample of 618 confined male homicide offenders selected from eight U.S. states, the current study examines the role of rape as a predictor of multiple homicide offending. Bivariate analyses indicated a significant association between rape and murder charges. Multivariate path regression models indicated that rape had a significant and robust association with multiple murder. This relationship withstood the confounding effects of kidnapping, prior prison confinement, and prior murder, rape, and kidnapping. These results provide evidence that rape potentially serves as a gateway to multiple murder for some serious offenders. Suggestions for future research are proffered.

Potential Effects of Oilseed Rape Expressing Oryzacystatin-1 (OC-1) and of Purified Insecticidal Proteins on Larvae of the Solitary Bee Osmia bicornis

Despite their importance as pollinators in crops and wild plants, solitary bees have not previously been included in non-target testing of insect-resistant transgenic crop plants. Larvae of many solitary bees feed almost exclusively on pollen and thus could be highly exposed to transgene products expressed in the pollen. The potential effects of pollen from oilseed rape expressing the cysteine protease inhibitor oryzacystatin-1 (OC-1) were investigated on larvae of the solitary bee Osmia bicornis ( = O. rufa). Furthermore, recombinant OC-1 (rOC-1), the Bt toxin Cry1Ab and the snowdrop lectin Galanthus nivalis agglutinin (GNA) were evaluated for effects on the life history parameters of this important pollinator. Pollen provisions from transgenic OC-1 oilseed rape did not affect overall development. Similarly, high doses of rOC-1 and Cry1Ab as well as a low dose of GNA failed to cause any significant effects. However, a high dose of GNA (0.1%) in the larval diet resulted in significantly increased development time and reduced efficiency in conversion of pollen food into larval body weight. Our results suggest that OC-1 and Cry1Ab expressing transgenic crops would pose a negligible risk for O. bicornis larvae, whereas GNA expressing plants could cause detrimental effects, but only if bees were exposed to high levels of the protein. The described bioassay with bee brood is not only suitable for early tier non-target tests of transgenic plants, but also has broader applicability to other crop protection products. PMID:18628826

A Four-Year Field Program Investigating Long-Term Effects of Repeated Exposure of Honey Bee Colonies to Flowering Crops Treated with Thiamethoxam

2013-01-01

Neonicotinoid residues in nectar and pollen from crop plants have been implicated as one of the potential factors causing the declines of honey bee populations. Median residues of thiamethoxam in pollen collected from honey bees after foraging on flowering seed treated maize were found to be between 1 and 7 µg/kg, median residues of the metabolite CGA322704 (clothianidin) in the pollen were between 1 and 4 µg/kg. In oilseed rape, median residues of thiamethoxam found in pollen collected from bees were between <1 and 3.5 µg/kg and in nectar from foraging bees were between 0.65 and 2.4 µg/kg. Median residues of CGA322704 in pollen and nectar in the oilseed rape trials were all below the limit of quantification (1 µg/kg). Residues in the hive were even lower in both the maize and oilseed rape trials, being at or below the level of detection of 1 µg/kg for bee bread in the hive and at or below the level of detection of 0.5 µg/kg for hive nectar, honey and royal jelly samples. The long-term risk to honey bee colonies in the field was also investigated, including the sensitive overwintering stage, from four years consecutive single treatment crop exposures to flowering maize and oilseed rape grown from thiamethoxam treated seeds at rates recommended for insect control. Throughout the study, mortality, foraging behavior, colony strength, colony weight, brood development and food storage levels were similar between treatment and control colonies. Detailed examination of brood development throughout the year demonstrated that colonies exposed to the treated crop were able to successfully overwinter and had a similar health status to the control colonies in the following spring. We conclude that these data demonstrate there is a low risk to honey bees from systemic residues in nectar and pollen following the use of thiamethoxam as a seed treatment on oilseed rape and maize.

Perry, Rachel; Murphy, Molly; Rankin, Kristin M; Cowett, Allison; Harwood, Bryna

2016-01-01

We aimed to explore current practices regarding screening for rape and response to disclosure of rape-related pregnancy in the abortion care setting. We performed a cross-sectional, nonprobability survey of U.S. abortion providers. Individuals were recruited in person and via emailed invitations to professional organization member lists. Questions in this web-based survey pertained to providers' practice setting, how they identify rape-related pregnancy, the availability of support services, and their experiences with law enforcement. Providers were asked their perceptions of barriers to care for women who report rape-related pregnancy. Surveys were completed by 279 providers (21% response rate). Most respondents were female (93.1%), and the majority were physicians in a clinical role (69.4%). One-half (49.8%) reported their practice screens for pregnancy resulting from rape, although fewer (34.8%) reported that screening is the method through which most patients with this history are identified. Most (80.6%) refer women with rape-related pregnancy to support services such as rape crisis centers. Relatively few (19.7%) have a specific protocol for care of women who report rape-related pregnancy. Clinics that screen were 79% more likely to have a protocol for care than centers that do not screen. Although the majority (67.4%) reported barriers to identification of women with rape-related pregnancy, fewer (33.3%) reported barriers to connecting them to support services. Practices for identifying and providing care to women with rape-related pregnancy in the abortion care setting are variable. Further research should address barriers to care provision, as well as identifying protocols for care. Copyright © 2016 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Same-Sex and Race-Based Disparities in Statutory Rape Arrests.

PubMed

Chaffin, Mark; Chenoweth, Stephanie; Letourneau, Elizabeth J

2016-01-01

This study tests a liberation hypothesis for statutory rape incidents, specifically that there may be same-sex and race/ethnicity arrest disparities among statutory rape incidents and that these will be greater among statutory rape than among forcible sex crime incidents. 26,726 reported incidents of statutory rape as defined under state statutes and 96,474 forcible sex crime incidents were extracted from National Incident-Based Reporting System data sets. Arrest outcomes were tested using multilevel modeling. Same-sex statutory rape pairings were rare but had much higher arrest odds. A victim-offender romantic relationship amplified arrest odds for same-sex pairings, but damped arrest odds for male-on-female pairings. Same-sex disparities were larger among statutory than among forcible incidents. Female-on-male incidents had uniformly lower arrest odds. Race/ethnicity effects were smaller than gender effects and more complexly patterned. The findings support the liberation hypothesis for same-sex statutory rape arrest disparities, particularly among same-sex romantic pairings. Support for race/ethnicity-based arrest disparities was limited and mixed. © The Author(s) 2014.

Competitive disadvantage makes attitudes towards rape less negative.

PubMed

Nunes, Kevin L; Pettersen, Cathrine

2011-10-12

Evolutionary theorists have argued that perceived competitive disadvantage may lead to more positive evaluation of, and greater likelihood of engaging in, risky and antisocial behavior. However, experimental studies have not yet examined the effects of competitive disadvantage on perceptions of rape. In the current study, we created a manipulation of perceived competitive status to test its effects on beliefs about rape. In one condition, participants were made to feel disadvantaged relative to male peers in terms of financial, physical, and intellectual power, whereas in the other condition they were made to feel advantaged. Participants were 120 heterosexual male undergraduate students. The manipulation was effective; compared to participants in the advantage condition, those in the disadvantage condition rated themselves as significantly worse off financially, shorter, in worse physical shape, and as having lower course marks than the average male student at the university. Compared to perceived competitive advantage, perceived disadvantage led to less negative attitudes towards rape. However, perceived competitive status did not significantly affect justifications and excuses for rape. Future studies using similar experimental manipulations can complement correlational studies and may contribute to greater clarity, precision, and sophistication of research and theory on the role of competitive disadvantage in rape.

Although prior research has identified increases in cigarette smoking following trauma exposure, no studies have examined longitudinal trajectories of smoking following rape. The present investigation identifies and characterizes longitudinal (< 3 months, 3-6 months, and > 6 months post-assault) trajectories of smoking (N = 152) following a rape in a sample of 268 sexual assault victims participating in a forensic medical exam. Further, we examine acute predictors of subsequent smoking trajectories. Of participants endorsing smoking post-rape, a two-class solution was identified, with the majority of participants (74.6%) evidencing moderate smoking with a slight decrease over time and remaining participants showing heavy smoking with a slight increase over time. Having sustained an injury, minority status, and post-exam distress all predicted subsequent smoking trajectory. PMID:19370699

Women's erotic rape fantasies: an evaluation of theory and research.

PubMed

Critelli, Joseph W; Bivona, Jenny M

2008-01-01

This article is the first systematic review of the research literature on women's rape fantasies. Current research indicates that between 31% and 57% of women have fantasies in which they are forced into sex against their will, and for 9% to 17% of women these are a frequent or favorite fantasy experience. Erotic rape fantasies are paradoxical: they do not appear to make sense. Why would a person have an erotic and pleasurable fantasy about an event that, in real life, would be abhorrent and traumatic? In this article, the major theories of women's rape fantasies are evaluated both rationally and empirically. These theories explain rape fantasies in terms of masochism, sexual blame avoidance, openness to sexuality, sexual desirability, male rape culture, biological predisposition to surrender, sympathetic physiological activation, and adversary transformation. This article evaluates theory and research, makes provisional judgments as to which theories appear to be most viable, and begins the task of theoretical integration to arrive at a more complete and internally consistent explanation for why many women engage in erotic rape fantasies. Methodological critiques and programs for future research are presented throughout.

Correlates of reasons for not reporting rape to police: results from a national telephone household probability sample of women with forcible or drug-or-alcohol facilitated/incapacitated rape.

Cohn, Amy M; Zinzow, Heidi M; Resnick, Heidi S; Kilpatrick, Dean G

2013-02-01

Rape tactics, rape incident characteristics, and mental health problems (lifetime depression, PTSD, and substance abuse) were investigated as correlates of eight different reasons for not reporting a rape to police among women who had experienced but did not report a rape to police (n = 441) within a national telephone household probability sample. Rape tactics (nonmutually exclusive) included drug or alcohol-facilitated or incapacitated rape (DAFR/IR; n = 119) and forcible rape (FR; n = 376). Principal Components Analysis (PCA) was conducted to extract a dominant set of patterns among the eight reasons for not reporting, and to reduce the set of dependent variables. PCA results indicated three unique factors: Not Wanting Others to Know, Nonacknowledgment of Rape, and Criminal Justice Concerns. Hierarchical regression analyses showed DAFR/IR and FR were both positively and significantly associated with Criminal Justice Concerns, whereas DAFR/IR, but not FR, was associated with Nonacknowledgment as a reason for not reporting to police. Neither DAFR/IR nor FR emerged as significant predictors of Others Knowing after controlling for fear of death or injury at the time of the incident. Correlations among variables showed that the Criminal Justice Concerns factor was positively related to lifetime depression and PTSD and the Nonacknowledgement factor was negatively related to lifetime PTSD. Findings suggest prevention programs should educate women about the definition of rape, which may include incapacitation due to alcohol or drugs, to increase acknowledgement and decrease barriers to police reporting.

The unique associations between rape acknowledgment and the DSM-5 PTSD symptom clusters.

PubMed

Wilson, Laura C; Scarpa, Angela

2017-11-01

It is well documented in the sexual assault literature that more than half of rape survivors do not label their experience as rape. This is called unacknowledged rape. Although this phenomenon is common and undoubtedly has huge implications for psychotherapy, the impact of acknowledgment status on psychological adjustment is unclear. The present study aimed to delineate the unique impact of rape acknowledgment on psychopathology by examining PTSD symptoms at the cluster level. To examine this, 178 female college students who reported rape completed an online survey, including an assessment of PTSD symptoms in the past month. The results suggested that, after accounting for several covariates, acknowledged rape survivors reported significantly greater levels of intrusion and avoidance symptoms compared to unacknowledged rape survivors. The findings suggest that examining PTSD symptoms at the cluster level may provide more insight into the process of recovery following rape and therefore may better inform treatment decisions.

Baker, Katharine K

2003-06-01

This article presents a spectrum of sexual coersion. By looking at the social meaning of the different acts of coercion along the spectrum, the author suggests that most acts of sexual coercion can be classified as either rape (a sexual act with intent to do harm to the victim) or sex (a sexual act engaged in without any intent to harm the victim). Ironically, though, the author suggests that the most and least egregious acts of sexual aggression, that is, the acts we most readily identify as rape and the acts we are most reluctant to label rape are the ones that most easily evade explanation as either rape or sex.

To describe the socio-demographic along with the medico-legal characteristics of rape victims reporting to a female police station of Lahore. Observational study. Female Police Station in Shadman, Lahore, from, June 1995 to January 2009. A total of 74 cases of alleged rape victims were identified while reviewing all available police files concerning reported rapes and attempted rapes from 1995 to 2008. The data was gathered on preformed questionnaires after conducting the pilot study. All information about victims and alleged offenders were extracted from the police files including socio-demographic profile of the accused and victim both. Use of weapon, evidence of physical and genital trauma, assailant identification and his relationship with the victim, number of accused persons and location of rape was noted in each case. Examination by doctor and obtaining the specimens were also identified and was related to the outcome of the court case. Chi-square test was applied to determine the association of rape with age and educational status of the victim and the accused. A total of 74 cases of alleged rape were reported in the study period at Shadman Female Police Station. Maximum number of victims was reported in the age group 10-19 years (n=46, 62.2%). Majority of the accused belonged to 20-39 years' age group constituting 64.8% of the total. Regarding educational status 45 (60.8%) of the victims and 51 (68.9%) of the accused were illiterate. Significant association was found between the educational status of rape victims and accused (p = 0.016) but not between their ages (p = 0.862). The maximum incidence of rape was reported in unmarried (n = 55, 74.3%) and unemployed (n =61, 82.4%) women. In 14 cases (19%) use of weapon was reported. Physical trauma was reported in 29 (39%) and genital trauma in 14 (19%) cases. The accused were identified as family friends (25%) and neighbours (23%) respectively. Only 21% of the victims were examined by doctor and specimens were

Sucrose is the principal transported product of photosynthesis from source leaves to sink organs. SUTs/SUCs (sucrose transporters or sucrose carriers) and SWEETs (Sugars Will Eventually be Exported Transporters) play significant central roles in phloem loading and unloading. SUTs/SUCs and SWEETs are key players in sucrose translocation and are associated with crop yields. The SUT/SUC and SWEET genes have been characterized in several plant species, but a comprehensive analysis of these two gene families in oilseed rape has not yet been reported. In our study, 22 and 68 members of the SUT/SUCs and SWEET gene families, respectively, were identified in the oilseed rape (Brassica napus) genome through homology searches. An analysis of the chromosomal distribution, phylogenetic relationships, gene structures, motifs and the cis-acting regulatory elements in the promoters of BnSUC and BnSWEET genes were analyzed. Furthermore, we examined the expression of the 18 BnSUC and 16 BnSWEET genes in different tissues of “ZS11” and the expression of 9 BnSUC and 7 BnSWEET genes in “ZS11” under various conditions, including biotic stress (Sclerotinia sclerotiorum), abiotic stresses (drought, salt and heat), and hormone treatments (abscisic acid, auxin, cytokinin, brassinolide, gibberellin, and salicylic acid). In conclusion, our study provides the first comprehensive analysis of the oilseed rape SUC and SWEET gene families. Information regarding the phylogenetic relationships, gene structure and expression profiles of the SUC and SWEET genes in the different tissues of oilseed rape helps to identify candidates with potential roles in specific developmental processes. Our study advances our understanding of the important roles of sucrose transport in oilseed rape. PMID:27733861

This study examined male adolescents' self-report of rape of adolescent girls and the socio-demographic variables that correlated with self-report of rape. Descriptive-correlational design was used and the study was conducted in five public senior secondary schools in Ile-Ife, Nigeria. Three hundred and thirty-eight male adolescents participated in the study. A structured questionnaire was used to collect data. Findings from the study revealed the mean age of the adolescent males to be 16 years, with the majority (73%) of them in the middle adolescent stage. Six percent of the adolescent males reported they had raped an adolescent girl in the past. Among the boys who reported rape, 55% reported they had raped their sexual partners, and 55% reported they had perpetrated gang rape. Smoking (p = .0001), alcohol consumption (p = .001), and birth order (p = .006) predicted self-report of rape. The coefficient of birth order showed that odds of self-report of rape by first-born male increases by 6 times compared with other children. Study findings also provided evidence that adolescent males are moving from lone rape to gang rape in intimate partner relationships. Male adolescents are important group to target in rape prevention programs. © The Author(s) 2014.

Women's attitudes toward forcible rape.

PubMed

Tolor, A

1978-01-01

This study assessed the attitudes of women with diverse backgrounds toward possible responses to an attempted sexual assault and also ascertained their beliefs about how society should handle a convicted rapist. Additionally, the role which the personality dimensions of assertiveness and internal-external expectamcy play in shaping attitudes toward rape was investigated. Seventy-seven women and 25 men were administered the Rathus Assertiveness Schedule, the Rotter I-E Scale, and a Rape Inventory. Women relied on a narrow range of options to deal with a rapist's attack, depending mostly on less active modes. They advocated humane approaches be taken with convicted rapists. Personality played only a minor role.

The epidemiology of rape and sexual coercion in South Africa: an overview.

PubMed

Jewkes, Rachel; Abrahams, Naeema

2002-10-01

During 1999 the issue of rape in South Africa was debated at the highest levels. The epidemiology of rape has become an issue of considerable political importance and sensitivity, with President Mbeki demanding an answer to the question: how much rape is there in South Africa? The purpose of this paper is both to summarise and synthesise the findings of research to provide an overview of the epidemiology of rape of women in South Africa and to show how difficult it is to answer the President's question. The review begins by considering why rape is so difficult to research. Data available shows that rape reported to the police (240 incidents of rape and attempted rape per 100,000 women each year) represents the tip of an ice berg of sexual coercion. Representative community-based surveys have found, for example, that in the 17-48 age group there are 2070 such incidents per 100,000 women per year. Non-consensual sex in marriage and dating relationships is believed to be very common but is usually not well reported in surveys. Forced sexual initiation is reported by almost a third of adolescent girls. In addition coerced consensual sex is a common problem in schools, workplaces and amongst peers. Knowledge of causal and contributory factors influencing the high levels of rape are also discussed. We conclude that the rape statistic for the country is currently elusive but levels of non-consensual and coerced sex are clearly very high. International comparison needs to be approached with caution because most developing countries lack the infrastructure for accurate crime reporting and do not have such a substantial body of survey data.

A third of all rapes in Stockholm, the capital of Sweden, take place in public outdoor places. Yet, little is known about the events that precede this type of sexual offence and less about the situational context of rape. This study aims to improve the understanding of the nature of situational conditions that immediately precede events of rape. Using medical records of 147 rape victims during 2012 and 2013, we constructed time- and place-specific records of the places women traveled through or spent time at, the activities they engaged in, and the people they interacted with sequentially over the course of the day when they were raped. The analysis uses visualization tools (VISUAL-TimePAcTS), Geographical Information Systems, and conditional logistic regression to identify place-, context-, and social interaction-related factors associated with the onset of rape. Results for this sample of cases reported to hospitals show that being outdoors was not necessarily riskier for women when compared with indoor public settings; some outdoor environments were actually protective, such as streets. Being in a risky social context and engaging in a risky activity before the event was associated with an increased risk of rape, and the risk escalated over the day. Among those women who never drank alcohol, the results were similar to what was observed in the overall sample, which suggests that risky social interaction and risky activity made independent contributions to the risk of rape. The article finishes with suggestions for rape prevention.

Religiousness and Rape Myth Acceptance: Risk and Protective Effects.

Ensz, Samantha; Jankowski, Peter J

2017-03-01

This study addressed the lack of research simultaneously examining multiple dimensions of religiousness when predicting rape myth acceptance, and extended prior findings of a mediating role for right-wing authoritarianism (i.e., uncritical submission to authority and aggressive attitude toward those who do not conform to social norms) in the association between religiousness and prejudice. The sample consisted of 99 undergraduate and graduate students ( M age = 31.87 years, 66.7% female, 80.82% White, and 93% Christian affiliated) from a religiously affiliated university in the Midwest United States. As hypothesized, dimensions of religiousness exhibited differential associations with rape myth acceptance. Religious motivation characterized by openness and exploration (i.e., quest religiousness) was a significant negative predictor of rape myth acceptance, directly, and indirectly through right-wing authoritarianism. In contrast, rigid adherence to religious beliefs, assumed to be "right" and absolutely true (i.e., religious fundamentalism), and extrinsically motivated religiousness each exhibited a positive association with rape myth acceptance through right-wing authoritarianism. In addition, internally motivated religiousness and religious fundamentalism each moderated the nonlinear effect for quest predicting rape myth acceptance. Findings suggest that uncritical religious and secular submission to external authorities or uncommitted and nonexploring religiousness may have increased the extent to which persons adhered to rape myths, whereas religious exploration was protective. Practical implications center on the need for socioculturally relevant prevention and intervention efforts with religious identifying college students.

It's Her Fault: Student Acceptance of Rape Myths On Two College Campuses.

The present study examined factors that are associated with an individual's adherence to rape myths at two colleges located in the same town. Particularly, we examined sex, race, and participants' drinking behavior in relation to rape myth acceptance. We found that males and heavy drinkers are more likely than females and non/low drinkers to adhere to rape myths. An interaction between males and drinking was also found indicating a moderated effect of gender on rape myth acceptance. In addition, the college with sexual assault programming did not experience a lowered acceptance of rape myths compared with the college with no programming. © The Author(s) 2016.

Modelling the perennial energy crop market: the role of spatial diffusion

2013-01-01

Biomass produced from energy crops, such as Miscanthus and short rotation coppice is expected to contribute to renewable energy targets, but the slower than anticipated development of the UK market implies the need for greater understanding of the factors that govern adoption. Here, we apply an agent-based model of the UK perennial energy crop market, including the contingent interaction of supply and demand, to understand the spatial and temporal dynamics of energy crop adoption. Results indicate that perennial energy crop supply will be between six and nine times lower than previously published, because of time lags in adoption arising from a spatial diffusion process. The model simulates time lags of at least 20 years, which is supported empirically by the analogue of oilseed rape adoption in the UK from the 1970s. This implies the need to account for time lags arising from spatial diffusion in evaluating land-use change, climate change (mitigation or adaptation) or the adoption of novel technologies.

Suberin-derived substituted fatty acids have been shown to be potential biomarkers for plant-derived carbon (C) in soils across ecosystems. Analyzing root derived suberin compounds bound in soil could help to understand the root input into a soil organic carbon pool. In this study, bound lipids were extracted and identified in root and topsoil samples. Short-chain suberin diacids were quantified under rice (Oryza sativa L.) and rape (Brassica campestris) rotations with different cultivar combinations in a Chinese rice paddy. After removal of free lipids with sequential extraction, the residual bound lipids were obtained with saponification and derivatization before analysis using gas chromatography–mass spectrometry (GC-MS). Diacids C16 and C18 in bound lipids were detected both in rice and rape root samples, while diacids C20 and C22 were detected only in rape root samples. Accordingly, diacids were quantified in both rhizosphere and bulk soil (0–15 cm). The amount of total root-derived diacids in bulk soil varied in a range of 5.6–9.6 mg/kg across growth stages and crop seasons. After one year-round rice-rape rotation, root-derived suberin diacids were maintained at a level of 7–9 mg/kg in bulk soil; this was higher under a super rice cultivar LY than under a hybrid cultivar IIY. While concentrations of the analyzed diacids were generally higher in rhizosphere than in bulk soil, the total diacid (DA) concentration was higher at the time of rape harvest than at rice harvest, suggesting that rape roots made a major contribution to the preservation of diacids in the paddy. Moreover, the net change in the concentration and the ratios of C16:0 DA to C18:1 DA, and of C16:0 DA to C18:0 DA, over a whole growing season, were greater under LY than under IIY, though there was no difference between cultivars within a single growth stage. Overall, total concentration of root-derived suberin diacids was found to be positively correlated to soil organic carbon

Attitude May Be Everything, But Is Everything an Attitude? Cognitive Distortions May Not Be Evaluations of Rape.

PubMed

Nunes, Kevin L; Hermann, Chantal A; White, Kristen; Pettersen, Cathrine; Bumby, Kurt

2018-02-01

Cognitive distortions are often referred to as attitudes toward rape in theory, research, and clinical practice pertaining to sexual aggression. In the social-psychological literature, however, attitudes are typically defined as evaluations; thus, in this context, attitudes toward rape are considered evaluations of rape (e.g., rape is negative vs. positive). The purpose of the current study was to explore whether a widely used measure of cognitive distortions (RAPE Scale; Bumby, 1996) assesses evaluation of rape, and, if not, whether evaluation of rape and the cognitions assessed by the RAPE Scale are independently associated with sexually aggressive behavior. Participants (660 male undergraduate students) completed the RAPE Scale as well as measures of evaluation of rape and sexually aggressive behavior. An exploratory factor analysis revealed that the RAPE Scale items formed a correlated but distinct factor from the Evaluation of Rape Scale items. Regression analyses indicated that the Evaluation of Rape Scale and the RAPE Scale had small to moderate independent associations with self-report measures of sexually aggressive behavior. Our results suggest that evaluation of rape may be distinct from cognitive distortions regarding rape, and both evaluation and cognitive distortions may be relevant for understanding sexual violence.

Boron nutrition and chilling tolerance of warm climate crop species.

PubMed

Huang, Longbin; Ye, Zhengqian; Bell, Richard W; Dell, Bernard

2005-10-01

Field observations and glasshouse studies have suggested links between boron (B)-deficiency and leaf damage induced by low temperature in crop plants, but causal relationships between these two stresses at physiological, biochemical and molecular levels have yet to be explored. Limited evidence at the whole-plant level suggests that chilling temperature in the root zone restricts B uptake capacity and/or B distribution/utilization efficiency in the shoot, but the nature of this interaction depends on chilling tolerance of species concerned, the mode of low temperature treatment (abrupt versus gradual temperature decline) and growth conditions (e.g. photon flux density and relative humidity) that may exacerbate chilling stress. This review explores roles of B nutrition in chilling tolerance of continual root or transient shoot chills in crop species adapted to warm season conditions. It reviews current research on combined effects of chilling temperature (ranging from >0 to 20 degrees C) and B deficiency on growth and B nutrition responses in crop species differing in chilling tolerance. For subtropical/tropical species (e.g. cucumber, cassava, sunflower), root chilling at 10-17 degrees C decreases B uptake efficiency and B utilization in the shoot and increases the shoot : root ratio, but chilling-tolerant temperate species (e.g. oilseed rape, wheat) require much lower root chill temperatures (2-5 degrees C) to achieve the same responses. Boron deficiency exacerbates chilling injuries in leaf tissues, particularly under high photon flux density. Suggested mechanisms for B x chilling interactions in plants are: (a) chilling-induced reduction in plasmalemma hydraulic conductivity, membrane fluidity, water channel activity and root pressure, which contribute to the decrease in root hydraulic conductance, water uptake and associated B uptake; (b) chilling-induced stomatal dysfunction affecting B transport from root to shoot and B partitioning in the shoot; and (c) B

A statewide evaluation of services provided to rape survivors.

2004-02-01

This article presents the descriptive results of a statewide evaluation of hotline, advocacy, and counseling services provided to sexual assault victims in Illinois. Collaborative efforts of a multidisciplinary research team and sexual assault service providers resulted in victim-sensitive evaluation measures and data that reflect, for the first time, the collective impact of services on rape victims across the state of Illinois. Results of the evaluation suggest that, overall, services provided to rape victims provided support, increased information and knowledge, and helped victims to understand options and make decisions. The evaluation approach is notable for its collaborative nature and its sensitivity to rape victims during help-seeking and delivery; however, due to the high levels of distress common among rape survivors, some evaluation methods may not be appropriate for crisis intervention services such as hotline or advocacy. Implications for future evaluation research and policy are noted.

Rape and its relation to social disorganization, pornography and inequality in the USA.

PubMed

Baron, L; Straus, M A

1989-01-01

A theoretical model seeks to integrate social disorganization and feminist theories of rape, reporting an empirical test of that model using data on rapes per 100,000 population known to the police in the 50 states of the United States. The model includes the following aspects of the social organization of the states: social disorganization (measured by a six item index), sexual inequality (measured by a status of women index to men), pornography (measured by a sex magazine circulation index for eight sexually explicit magazines) and the level of culturally legitimate violence (measured by a 12 item legitimate violence index using indicators like corporal punishment in schools. There were marked differences between states of the USA in the incidence of rape during the 1980-82. Path analysis was used to test the theoretical model, which posits rape as a function of the direct and indirect effects of social disorganization, sexual inequality, pornography, legitimate violence and seven control variables. The results show that all four variables play an important part in explaining differences between states in rape; and that together, the variables in the model explain 83 per cent of the state-to-state variation in rape. Women are in much greater danger of being raped in some American states than in others. Since the FBI began compiling statistics on rape, states like Alaska, Nevada, and California have consistently registered many more rapes per capita than North Dakota, Maine, and Iowa. What factors account for such differences between states? Could the variation in the rape rate be explained by four aspects of the social structure of states: (1) the proliferation of pornography (2) sexual inequality (3) culturally legitimate violence and (4) social disorganization. Each factor represents a theory which will be examined within the context of an integrated theory on rape.

The purpose of this study was to assess the relationships among campus violence, student drinking levels, and the physical availability of alcohol at off-campus outlets in a multisite design. An ecological analysis of on-campus violence was conducted at 32 U.S. colleges. Dependent variables included campus-reported rates of rape, robbery, assault, and burglary obtained from a U.S. Department of Education online database for the years 2000-2004. Measures of student alcohol use and demographics were obtained from student surveys conducted for the Social Norms Marketing Research Project from 2000 to 2004. Measures of alcohol-outlet density within 3 miles of each campus were obtained from state alcohol-licensing authorities for 2004. Both on- and off-premise alcohol-outlet densities were associated with the campus rape-offense rate but not with the assault or robbery rates. Student drinking level was associated with both campus rape and assault rates but not with the campus robbery rate. The apparent effect of on-premise outlet density on campus rape-offense rates was reduced when student drinking level was included in the model, suggesting that the effect of on-premise outlet density may be mediated by student drinking level. Separate analyses revealed a similar mediational role for off-premise outlet density. These findings demonstrate that there is a campus-level association between sexual violence and the campus-community alcohol environment.

Faulty perceptions? The impact of binge drinking history on college women's perceived rape resistance efficacy.

PubMed

McCauley, Jenna L; Calhoun, Karen S

2008-12-01

College women who binge drink are at greater risk than their peers for experiencing an alcohol-involved rape. Evidence suggests that these women commonly underestimate their risk for assault. This study examines college women's perceptions of their rape resistance efficacy in two acquaintance rape scenarios (one involving the woman's alcohol consumption and one not) as a function of their binge drinking and alcohol-involved rape history. Alcohol-involved rape was inversely associated only with efficacy in situations involving alcohol. Binge drinking was differentially predictive of efficacy in the two scenarios, with regular binge drinkers being significantly more likely to have high perceived efficacy in rape scenarios in which they were drinking and significantly less likely than their peers to have high perceived efficacy in rape scenarios in which they weren't drinking. Findings have direct implications for both college drinking and rape risk reduction interventions, highlighting the need to address women's minimization of alcohol's impact on their rape resistance ability.

Date rape among Cypriot female college students: an explorative study.

This study examined the prevalence and reporting of date rape among female college students (aged 18-24) in Cyprus and assessed the students' attitudes and awareness regarding date rape. In addition, the study examined how date rape is perceived among representatives of related private and governmental organizations in Cyprus. This is part of a larger multi-country study. This paper will focus only on the results pertaining to Cyprus. The study was coordinated by the Mediterranean Institute of Gender Studies. This study used quantitative and qualitative methods. In total, 476 female college students responded to an anonymous questionnaire, two focus group discussions were carried out, and five key-informant interviews with relevant institutional representatives were conducted. The results of the study indicated that unwanted sexual experiences and sexual violence, including date rape, do exist among young Cypriot women. Specifically, 1.3% of the research participants reported experiencing an attempted rape by their date, and 1.9 % of the study participants reported being raped on a date. Often this was caused by their boyfriend, friend or sexual partner (54.2%). The results of the qualitative study showed that young female Cypriots agreed that many women give in to psychological pressure because they feel guilty about letting the other person down or because they 'didn't satisfy him' or fear they might lose him. Despite the explorative nature of the study, it is significant as research on date rape in Cyprus is almost non-existent. The authors anticipate that the results of the study will be useful to other researchers and policy-makers involved in this area of research.

Who Helps the Helpers? Social Support for Rape Crisis Advocates.

Houston-Kolnik, Jaclyn D; Odahl-Ruan, Charlynn A; Greeson, Megan R

2017-08-01

Secondary exposure to trauma may have negative effects on rape victim advocates' well-being. Self-care can help to mitigate these negative effects on advocates' well-being, and prior research suggests that social support is an especially important aspect of advocates' self-care. However, there is a lack of research on how rape crisis advocates access and receive social support in relationship to their advocacy work. Therefore, semistructured qualitative interviews were conducted with 15 rape crisis advocates who volunteered for a rape crisis center in Chicago to understand how they accessed social support from informal and formal support providers, and when they did receive support, what was helpful versus unhelpful. Data were analyzed using thematic content analysis. Results revealed that many advocates were able to seek out and receive positive instrumental and emotional social support that nurtured them and their work. However, advocates also experienced a variety of barriers to obtaining positive support from informal support providers, including fear of burdening providers and a reluctance or lack of preparedness of their support providers to speak about the issue. Advocates emphasized the need for rape crisis centers to provide resources for their informal social support systems in order to encourage helpful responses. In addition, advocates praised the rape crisis center for its built-in formal support structures, but also encouraged the organization to seek broader representation of persons from minority backgrounds among their advocates and mentors. Implications and future directions for research and rape crisis centers are also discussed. The present study highlights the importance of social support systems for advocates and potential barriers that may be addressed to reduce service provider burnout and vicarious trauma.

Pelvic floor muscle problems mediate sexual problems in young adult rape victims.

Prior studies have addressed sexual abuse and sexual function in adult women. No studies have focused on the effect of adolescence rape on sexual functioning. To investigate the effect of rape on sexual problems and on pelvic floor problems, as well as the mediating role of pelvic floor problems on sexual problems, in a homogenous group of victims of adolescence rape without a history of childhood sexual, physical, and/or emotional abuse. Sexual functioning and pelvic floor functioning were assessed using self-report questionnaires. In this cross-sectional study, a group of 89 young women aged 18-25 years who were victimized by rape in adolescence was compared with a group of 114 nonvictimized controls. The rape victims were treated for posttraumatic stress disorder (PTSD) 3 years prior to participation in the study. Three years posttreatment, rape victims were 2.4 times more likely to have a sexual dysfunction (lubrication problems and pain) and 2.7 times more likely to have pelvic floor dysfunction (symptoms of provoked vulvodynia, general stress, lower urinary tract, and irritable bowel syndrome) than nonvictimized controls. The relationship between rape and sexual problems was partially mediated by the presence of pelvic floor problems. Rape victims and controls did not differ with regard to sexual activities. Rape victims suffer significantly more from sexual dysfunction and pelvic floor dysfunction when compared with nontraumatized controls, despite the provision of treatment for PTSD. Possibly, physical manifestations of PTSD have been left unaddressed in treatment. Future treatment protocols should consider incorporating (physical or psychological) treatment strategies for sexual dysfunction and/or pelvic floor dysfunction into trauma exposure treatments. © 2013 International Society for Sexual Medicine.

The prediction of false rape-related beliefs (rape myth acceptance [RMA]) was examined using the Illinois Rape Myth Acceptance Scale (Payne, Lonsway, & Fitzgerald, 1999) among a nonclinical sample of 258 male and female college students. Predictor variables included measures of attitudes toward women, gender role identity (GRI), sexual trauma history, and posttraumatic stress disorder (PTSD) symptom severity. Using linear regression and testing interaction effects, negative attitudes toward women significantly predicted greater RMA for individuals without a sexual trauma history. However, neither attitudes toward women nor GRI were significant predictors of RMA for individuals with a sexual trauma history. PTSD did not moderate RMA's relationship with attitudes toward women and GRI. This study has clinical implications for treatment as well as for the development of rape myth-dispelling programs.

2011-09-01

To investigate the dynamic distribution patterns of nitrous oxide (N2O) in the soil profiles in paddy fields with different rice-upland crop rotation systems, a special soil gas collection device was adopted to monitor the dynamics of N2O at the soil depths 7, 15, 30, and 50 cm in the paddy fields under both flooding and drainage conditions. Two rotation systems were installed, i.e., wheat-single rice and oilseed rape-double rice, each with or without nitrogen (N) application. Comparing with the control, N application promoted the N2O production in the soil profiles significantly (P < 0.01), and there existed significant correlations in the N2O concentration among the four soil depths during the whole observation period (P < 0.01). In the growth seasons of winter wheat and oilseed rape under drainage condition and with or without N application, the N2O concentrations at the soil depths 30 cm and 50 cm were significantly higher than those at the soil depths 7 cm and 15 cm; whereas in the early rice growth season under flooding condition and without N application, the N2O concentrations at the soil depth 7 cm and 15 cm were significantly higher than those at the soil depths 30 cm and 50 cm (P < 0.05). No significant differences were observed in the N2O concentrations at the test soil depths among the other rice cropping treatments. The soil N2O concentrations in the treatments without N application peaked in the transitional period from the upland crops cropping to rice planting, while those in the treatments with N application peaked right after the second topdressing N of upland crops. Relatively high soil N2O concentrations were observed at the transitional period from the upland crops cropping to rice planting.

The measurement of rape is among the leading methodological issues in the violence against women field. Methodological discussion continues to focus on decreasing measurement errors and improving the accuracy of rape estimates. The current study used a quasi-experimental design to examine the effect of survey question wording on estimates of completed and attempted rape and verbal threats of rape. Specifically, the study statistically compares self-reported rape estimates from two nationally representative studies of college women's sexual victimization experiences, the National College Women Sexual Victimization study and the National Violence Against College Women study. Results show significant differences between the two sets of rape estimates, with National Violence Against College Women study rape estimates ranging from 4.4% to 10.4% lower than the National College Women Sexual Victimization study rape estimates. Implications for future methodological research are discussed.

This study estimated the per-victim U.S. lifetime cost of rape. Data from previous studies was combined with current administrative data and 2011 U.S. National Intimate Partner and Sexual Violence Survey data in a mathematical model. Rape was defined as any lifetime completed or attempted forced penetration or alcohol- or drug-facilitated penetration, measured among adults not currently institutionalized. Costs included attributable impaired health, lost productivity, and criminal justice costs from the societal perspective. Average age at first rape was assumed to be 18 years. Future costs were discounted by 3%. The main outcome measures were the average per-victim (female and male) and total population discounted lifetime cost of rape. Secondary outcome measures were marginal outcome probabilities among victims (e.g., suicide attempt) and perpetrators (e.g., incarceration) and associated costs. Analysis was conducted in 2016. The estimated lifetime cost of rape was $122,461 per victim, or a population economic burden of nearly $3.1 trillion (2014 U.S. dollars) over victims' lifetimes, based on data indicating >25 million U.S. adults have been raped. This estimate included $1.2 trillion (39% of total) in medical costs; $1.6 trillion (52%) in lost work productivity among victims and perpetrators; $234 billion (8%) in criminal justice activities; and $36 billion (1%) in other costs, including victim property loss or damage. Government sources pay an estimated $1 trillion (32%) of the lifetime economic burden. Preventing sexual violence could avoid substantial costs for victims, perpetrators, healthcare payers, employers, and government payers. These findings can inform evaluations of interventions to reduce sexual violence. Published by Elsevier Inc.

Collins, Brittany; Fischer, Sarah; Stojek, Monika; Becker, Kendra

2014-02-01

This study utilizes a prospective design to examine the interaction of recent rape/attempted rape with individual differences in thought suppression on increases in disordered eating symptoms during late adolescence/emerging adulthood. Thought suppression is the attempt to suppress unwanted thoughts. We propose that emerging adult women who have experienced recent rape/attempted rape and tend to use thought suppression as a coping mechanism are at risk for increases in disordered eating. 319 women completed the Eating Disorder Examination Questionnaire, the Sexual Experiences Survey, the Childhood Trauma Questionnaire, and the White Bear Thought Suppression Inventory in their first month of college and three months later. The experience of recent rape/attempted rape in the three months prior to the assessment accounted for unique variance in disordered eating at Time 2. Levels of thought suppression assessed at Time 1 significantly moderated the influence of recent rape/attempted rape on disordered eating at Time 2.

2007-08-01

Services provided to rape victims by human service professionals are usually helpful but are occasionally very harmful in that the victim ends up feeling 're-victimized'. This may be caused by the attitudes of the professionals towards the victims based on beliefs regarding rape and gender roles. Japanese human service professionals were solicited for responses to the Rape Myth Scale (RMS) and the short form of the Scale of Egalitarian Sex Role Attitudes (SESRA-S). One interpretable factor was extracted according to an exploratory factor analysis. Impact of the participants' age, sex, residential area, and type of profession on rape myth acceptance were examined by four-way layout ANOVA.

Furthermore, a structural equation model showing the contribution of sex role egalitarian attitude to rape myth acceptance was established.

Terminated small grain cover crops are valuable in light textured soils to reduce wind and rain erosion and for protection of young cotton seedlings. A three-year study was conducted to determine the impact of terminated small grain winter cover crops, which are hosts for Meloidogyne incognita, on cotton yield, root galling and nematode midseason population density. The small plot test consisted of the cover treatment as the main plots (winter fallow, oats, rye and wheat) and rate of aldicarb applied in-furrow at-plant (0, 0.59 and 0.84 kg a.i./ha) as subplots in a split-plot design with eight replications, arranged in a randomized complete block design. Roots of 10 cotton plants per plot were examined at approximately 35 days after planting. Root galling was affected by aldicarb rate (9.1, 3.8 and 3.4 galls/root system for 0, 0.59 and 0.84 kg aldicarb/ha), but not by cover crop. Soil samples were collected in mid-July and assayed for nematodes. The winter fallow plots had a lower density of M. incognita second-stage juveniles (J2) (transformed to Log10 (J2 + 1)/500 cm3 soil) than any of the cover crops (0.88, 1.58, 1.67 and 1.75 Log10(J2 + 1)/500 cm3 soil for winter fallow, oats, rye and wheat, respectively). There were also fewer M. incognita eggs at midseason in the winter fallow (3,512, 7,953, 8,262 and 11,392 eggs/500 cm3 soil for winter fallow, oats, rye and wheat, respectively). Yield (kg lint per ha) was increased by application of aldicarb (1,544, 1,710 and 1,697 for 0, 0.59 and 0.84 kg aldicarb/ha), but not by any cover crop treatments. These results were consistent over three years. The soil temperature at 15 cm depth, from when soils reached 18°C to termination of the grass cover crop, averaged 9,588, 7,274 and 1,639 centigrade hours (with a minimum threshold of 10°C), in 2005, 2006 and 2007, respectively. Under these conditions, potential reproduction of M. incognita on the cover crop did not result in a yield penalty. PMID:19259531

Bergen, R K

1995-06-01

This article investigates how women define their experiences of marital rape and cope with the violence. The study is based on in-depth interviews conducted among 35 survivors of marital rape. It found out that women's definition of sexual violence often change over the course of the relationship in a similar manner, from seeing the sexual attacks as an aberrant incident, to redefining the incident as rape, to terminating the relationship with a ¿rapist¿. This study further describes the 6 stages through which women pass in coping with the violence, which include entering a violent relationship; managing the violence; experiencing a loss of self; redefining the violence; ending the violence; and recovering from the trauma. This study, however, gives particular attention to understanding how women manage the violence and redefine their experiences as rape. It concludes by acknowledging that marital rape is a serious problem with very real consequences for the women who experience it.

Factors Related to Rape Reporting Behavior in Brazil: Examining the Role of Spatio-Temporal Factors.

2016-07-01

The reporting of rape to police is an important component of this crime to have the criminal justice system involved and, potentially, punish offenders. However, for a number of reasons (fear of retribution, self-blame, etc.), most rapes are not reported to police. Most often, the research investigating this phenomenon considers incident and victim factors with little attention to the spatio-temporal factors of the rape. In this study, we consider incident, victim, and spatio-temporal factors relating to rape reporting in Campinas, Brazil. Our primary research question is whether or not the spatio-temporal factors play a significant role in the reporting of rape, over and above incident and victim factors. The subjects under study are women who were admitted to the Women's Integrated Healthcare Center at the State University of Campinas, Brazil, and surveyed by a psychologist or a social worker. Rape reporting to police was measured using a dichotomous variable. Logistic regression was used to predict the probability of rape reporting based on incident, victim, and spatio-temporal factors. Although we find that incident and victim factors matter for rape reporting, spatio-temporal factors (rape/home location and whether the rape was in a private or public place) play an important role in rape reporting, similar to the literature that considers these factors. This result has significant implications for sexual violence education. Only when we know why women decide not to report a rape may we begin to work on strategies to overcome these hurdles.

Prospective Study of Rape Perpetration by Young South African Men: Incidence & Risk Factors

PubMed Central

Jewkes, Rachel; Nduna, Mzikazi; Jama Shai, Nwabisa; Dunkle, Kristin

2012-01-01

Background There has been very little prospective research on rape perpetration among men. This paper describes the incidence and risk factors for new rape and attempted rape events among young South African men in an HIV prevention trial. Methods We followed 1,147 men aged 15–26 years who enrolled into a cluster randomised controlled trial to evaluate the HIV prevention behavioural intervention Stepping Stones. Incidence rate ratios for factors associated with incident rape were derived from Poisson models. Results The young men reported 217 incident rapes (completed or attempted) of a girl or woman over 1,914 person years of follow up, yielding a rape incidence of 11.2 per 100 person years. Overall 24.9% of men had previously raped at baseline, and 18.9% did so during the follow up. Among the latter, 61.3% raped for the first time, and 38.7% re-offended. Multivariable Poisson modelling showed a higher incidence of rape perpetration among men who had ever used drugs (IRR 1.86 95%CI 1.39, 2.49), had eight or more lifetime partners (IRR 1.48 95% CI 1.09, 2.01), had been physically violent toward a female partner (IRR 1.50 95%CI 1.11, 2.03) and had disclosed rape perpetration at baseline (IRR 1.45 95%CI 1.07, 1.97). A lower incidence was found among those with greater resistance to peer pressure (IRR 0.85 95%CI 0.74, 0.97). Conclusions The findings highlight the importance of male gender socialisation and addressing delinquent youth sub-cultures in rape prevention. Prevention requires change in hegemonic masculinity, with its emphasis on gender hierarchy, exaggerated performance of heterosexuality and control of women. Interventions are needed to address male socialisation with delinquent peers, by reducing exposure to childhood trauma and strengthening opportunities for gainful employment (in work or recreation).

Chronic exposure to neonicotinoid insecticides has been linked to reduced survival of pollinating insects at both the individual and colony level, but so far only experimentally. Analyses of large-scale datasets to investigate the real-world links between the use of neonicotinoids and pollinator mortality are lacking. Moreover, the impacts of neonicotinoid seed coatings in reducing subsequent applications of foliar insecticide sprays and increasing crop yield are not known, despite the supposed benefits of this practice driving widespread use. Here, we combine large-scale pesticide usage and yield observations from oilseed rape with those detailing honey bee colony losses over an 11 year period, and reveal a correlation between honey bee colony losses and national-scale imidacloprid (a neonicotinoid) usage patterns across England and Wales. We also provide the first evidence that farmers who use neonicotinoid seed coatings reduce the number of subsequent applications of foliar insecticide sprays and may derive an economic return. Our results inform the societal discussion on the pollinator costs and farming benefits of prophylactic neonicotinoid usage on a mass flowering crop.

Adverse weather impacts on arable cropping systems

NASA Astrophysics Data System (ADS)

Gobin, Anne

2016-04-01

Damages due to extreme or adverse weather strongly depend on crop type, crop stage, soil conditions and management. The impact is largest during the sensitive periods of the farming calendar, and requires a modelling approach to capture the interactions between the crop, its environment and the occurrence of the meteorological event. The hypothesis is that extreme and adverse weather events can be quantified and subsequently incorporated in current crop models. Since crop development is driven by thermal time and photoperiod, a regional crop model was used to examine the likely frequency, magnitude and impacts of frost, drought, heat stress and waterlogging in relation to the cropping season and crop sensitive stages. Risk profiles and associated return levels were obtained by fitting generalized extreme value distributions to block maxima for air humidity, water balance and temperature variables. The risk profiles were subsequently confronted with yields and yield losses for the major arable crops in Belgium, notably winter wheat, winter barley, winter oilseed rape, sugar beet, potato and maize at the field (farm records) to regional scale (statistics). The average daily vapour pressure deficit (VPD) and reference evapotranspiration (ET0) during the growing season is significantly lower (p < 0.001) and has a higher variability before 1988 than after 1988. Distribution patterns of VPD and ET0 have relevant impacts on crop yields. The response to rising temperatures depends on the crop's capability to condition its microenvironment. Crops short of water close their stomata, lose their evaporative cooling potential and ultimately become susceptible to heat stress. Effects of heat stress therefore have to be combined with moisture availability such as the precipitation deficit or the soil water balance. Risks of combined heat and moisture deficit stress appear during the summer. These risks are subsequently related to crop damage. The methodology of defining

Since the year 2000, the number of rapes in Costa Rica has increased at a rate of 42 cases per year. In 2011, 1786 rape cases were reported to the prosecution offices throughout the country, but only 1081 reports continued through the investigation process by the Judicial Investigation Agency. A randomly collected sample of 272 reports received by Judicial Investigation Agency, between July 2012 and June 2013, were prospectively studied. The analysis was limited to cases reported within 30 days following the rape. Results indicate that most of the provinces in the country show an incidence of about 38 cases/100,000 inhabitants. Ninety-six percent of the victims were women, 50% of which were between 10 and 19 years old. More than 99.5% of violators were men. The rape was perpetrated by a single aggressor in 85% of the cases. It was found that 48% of the victims were within the first 11 days of their menstrual cycle at the time of the attack. Twenty-nine percent of rapes occurred in "high rape-risk" circumstances--e.g., victims attacked by strangers in public outdoors or indoors. Twenty-five percent of rapes occur in "moderate rape-risk" circumstances--e.g., victims attacked indoors at public locations or at the home other than the victim's by relatives, sentimental partners or acquaintances. Fifteen percent of rapes occurred in "low rape-risk" circumstances--e.g., victims attacked in their homes by relatives or sentimental partners. In 67% of the cases the perpetrator was an acquaintance of the victim. Eleven percent of the cases corresponded to rapes in which the perpetrator was a partner or ex-partner of the victim. Fourteen percent and 25% of rapes could be classified as "proactive drug-facilitated rapes" or "opportunistic drug-facilitated rapes", respectively. Semen in the vaginal fluid of victims and the genetic profile of the alleged perpetrator were detected in 55% and 33% of the cases, respectively. Copyright © 2014 Elsevier Ireland Ltd.

Soil phosphorus (P) fractions and runoff P concentration were measured to understand the fate of soil P entering surface runoff water during summer cropping season of different double cropping systems under two fertilizer regimes. The dominant form of runoff P was particulate P (PP). Runoff total P (TP) was higher at the vegetative growth stage and lower at the crop reproductive stage. TP and PP were derived mainly from soil Olsen-P, Al-P and Fe-P and amounts increased with sediment content in runoff water. Runoff P discharge was closely related to the changes in soil P forms. Soil Olsen-P, mainly consisting of some Ca2-P and Al-P, was increased by elevating fertilizer rate. Along with crop growth, there were active interconversions among Olsen-P, Org-P, Fe-P and O-Al-P in the soil, and some available P converted into Ca10-P, with O-Fe-P possibly being a transitional form for this conversion. The oilseed rape/corn system had less runoff TP at the early stage, and wheat/sweet potato system had a lower runoff P at the late stage. Intercropping corn with sweet potato in the field with oilseed rape as a previous crop may be helpful for alleviating runoff P load during the summer in this region. PMID:28650990

We isolated and characterized phosphate-dissolving endophytic bacteria from two commonly cultivated crops. Phosphate-dissolving endophytic bacteria were isolated by plating and screening from interior tissues of rape and maize plants on NBRIP medium with tricalcium phosphate as sole phosphate source. Bacteria were characterized regarding characteristics that may be relevant for a beneficial plant-microbe interaction-indoleacetic acid, siderophore and 1-aminocyclopropane-1-carboxylic acid deaminase production,and further classified by restriction analysis of 16S rDNA. Eleven typical strains were identified by 16S rDNA sequence analysis. Thirty-two phosphate-dissolving endophytic bacteria were isolated from maize and rape plants and classified by restriction analysis of 16S rDNA in 8 different taxonomic groups at the similarity level of 76%. All the isolates could release phosphate from tricalcium phosphate and decrease the pH of the medium. The maximum phosphate content (537.6 mg/L) in the solution was obtained with strain M1L5. Thirteen isolates isolated from rape produced indoleacetic acid and siderophore, 68.4% and 63.2% of the strains isolated from maize produced indoleacetic acid and siderophore,respectively. 63.2% of the strains isolated from maize were able to grow on 1-aminocyclopropane-1-carboxylic acid as the sole nitrogen source. The eleven strains belonged to five different genera including Pantoea, Pseudomonas, Burkholderia, Acinetobacter and Ralstonia. Phosphate-dissolving endophytic bacteria isolated from rape and maize plants have abundant characteristics relative to promoting plant growth and genetic diversity.

Experimental Study of Reciprocating Friction between Rape Stalk and Bionic Nonsmooth Surface Units

PubMed Central

Ma, Zheng; Li, Yaoming; Xu, Lizhang

2015-01-01

Background. China is the largest producer of rape oilseed in the world; however, the mechanization level of rape harvest is relatively low, because rape materials easily adhere to the cleaning screens of combine harvesters, resulting in significant cleaning losses. Previous studies have shown that bionic nonsmooth surface cleaning screens restrain the adhesion of rape materials, but the underlying mechanisms remain unclear. Objective. The reciprocating friction between rape stalk and bionic nonsmooth metal surface was examined. Methods. The short-time Fourier transform method was used to discriminate the stable phase of friction signals and the stick-lag distance was defined to analyze the stable reciprocating friction in a phase diagram. Results. The reciprocating friction between rape stalk and metal surface is a typical stick-slip friction, and the bionic nonsmooth metal surfaces with concave or convex units reduced friction force with increasing reciprocating frequency. The results also showed that the stick-lag distance of convex surface increased with reciprocating frequency, which indicated that convex surface reduces friction force more efficiently. Conclusions. We suggest that bionic nonsmooth surface cleaning screens, especially with convex units, restrain the adhesion of rape materials more efficiently compared to the smooth surface cleaning screens.

1982-01-01

The purpose of this research was to evaluate the potential yield and fuel quality of various oilseed crops adapted to the Pacific Northwest as a source of liquid fuel for diesel engines. The seed yield and oil production of three cultivars of winter rape (Brassica napus L.), two cultivars of safflower (Carthamus tinctorius L.) and two cultivars of sunflower (Helianthus annuus L.) were evaluated in replicated plots at Moscow. Additional trials were conducted at several locations in Idaho, Oregon and Washington. Sunflower, oleic and linoleic safflower, and low and high erucic acid rapeseed were evaluated for fatty acid composition, energymore » content, viscosity and engine performance in short term tests. During 20 minute engine tests power output, fuel economy and thermal efficiency were compared to diesel fuel. Winter rape produced over twice as much farm extractable oil as either safflower or sunflower. The winter rape cultivars, Norde and Jet Neuf had oil yields which averaged 1740 and 1540 L/ha, respectively. Vegetable oils contained 94 to 95% of the KJ/L of diesel fuel, but were 11.1 to 17.6 times more viscous. Viscosity of the vegetable oils was closely related to fatty acid chain length and number of unsaturated bonds (R/sup 2/=.99). During short term engine tests all vegetable oils produced power outputs equivalent to diesel, and had thermal efficiencies 1.8 to 2.8% higher than diesel. Based on these results it appears that species and cultivars of oilseed crops to be utilized as a source of fuel should be selected on the basis of oil yield. 1 figure, 5 tables.« less

Algerian abortion controversy highlights rape of war victims.

PubMed

Chelala, C

1998-05-09

This brief article highlights the change in Islamic practices to allow abortion for women raped during war situations in Algeria. The Islamic Supreme Council on April 12, 1998, issued an edict (fatwa) that allowed abortions for women attacked by Islamic extremists. This changes the prior prohibition of abortion, except in cases where the mother's life is in danger. The day after the edict, the newspapers Le Matin and La Tribune denied the existence of the edict, because the President's council did not request the change in Islamic law. The newspaper Al Khabar published the April 12, 1998, news of the edict and drew attention to the fate of over 1000 women and young girls raped during attacks. An estimated 70,000 people have been reported killed since 1992. The war was precipitated when the army nullified national elections that would have given the Islamic party political power. The Algerian Family Solidarity Ministry reports that as many as 1600 women, mostly aged 13-20 years, have been abducted and raped since 1994, by bands from the Armed Islamic Group. Figures are considered underestimates. Many women were able to escape from captors, but many of these women were pregnant. The stigma is so strong that many of these women will not be accepted home by their own families. In addition to those women who survived being raped, an estimated 2000 raped women were killed by their captors. The abductions have declined, but are still ongoing, especially around Algiers and near the Moroccan and Tunisian borders. The terrorists consider the act a "temporary marriage." Amnesty International and others have criticized the recent UN Human Rights Commission for not taking action in Algeria.

Wild pollinators have been shown to enhance the pollination of Brassica napus (oilseed rape) and thus increase its market value. Several studies have previously shown that pollination services are greater in crops adjoining forest patches or other seminatural habitats than in crops completely surrounded by other crops. In this study, we investigated the specific importance of forest edges in providing potential pollinators in B. napus fields in two areas in France. Bees were caught with yellow pan traps at increasing distances from both warm and cold forest edges into B. napus fields during the blooming period. A total of 4594 individual bees, representing six families and 83 taxa, were collected. We found that both bee abundance and taxa richness were negatively affected by the distance from forest edge. However, responses varied between bee groups and edge orientations. The ITD (Inter-Tegular distance) of the species, a good proxy for bee foraging range, seems to limit how far the bees can travel from the forest edge. We found a greater abundance of cuckoo bees (Nomada spp.) of Andrena spp. and Andrena spp. males at forest edges, which we assume indicate suitable nesting sites, or at least mating sites, for some abundant Andrena species and their parasites (Fig. 1). Synthesis and Applications. This study provides one of the first examples in temperate ecosystems of how forest edges may actually act as a reservoir of potential pollinators and directly benefit agricultural crops by providing nesting or mating sites for important early spring pollinators. Policy-makers and land managers should take forest edges into account and encourage their protection in the agricultural matrix to promote wild bees and their pollination services.

War rape, natality and genocide.

PubMed

Schott, Robin May

2011-01-01

Feminist philosophy can make an important contribution to the field of genocide studies, and issues relating to gender and war are gaining new attention. In this article I trace legal and philosophical analyses of sexual violence against women in war. I analyze the strengths and limitations of the concept of social death—introduced into this field by Claudia Card—for understanding the genocidal features of war rape, and draw on the work of Hannah Arendt to understand the central harm of genocide as an assault on natality. The threat to natality posed by the harms of rape, forced pregnancy and forced maternity lie in the potential expulsion from the public world of certain groups—including women who are victims, members of the 'enemy' group, and children born of forced birth.

While rape is ordinarily considered an invariable reality, Sharon Marcus argues that it is instead a cultural script, which casts women as victims and men as perpetrators. In imagining rape as a script, it may seem pertinent to suggest that the arts and performance have a role in its prevention. Performances can provide a forum to publicly reflect…

Flowering, the transition from the vegetative to the generative phase, is a decisive time point in the lifecycle of a plant. Flowering is controlled by a complex network of transcription factors, photoreceptors, enzymes and miRNAs. In recent years, several studies gave rise to the hypothesis that this network is also strongly involved in the regulation of other important lifecycle processes ranging from germination and seed development through to fundamental developmental and yield-related traits. In the allopolyploid crop species Brassica napus, (genome AACC), homoeologous copies of flowering time regulatory genes are implicated in major phenological variation within the species, however the extent and control of intraspecific and intergenomic variation among flowering-time regulators is still unclear. To investigate differences among B. napus morphotypes in relation to flowering-time gene variation, we performed targeted deep sequencing of 29 regulatory flowering-time genes in four genetically and phenologically diverse B. napus accessions. The genotype panel included a winter-type oilseed rape, a winter fodder rape, a spring-type oilseed rape (all B. napus ssp. napus) and a swede (B. napus ssp. napobrassica), which show extreme differences in winter-hardiness, vernalization requirement and flowering behavior. A broad range of genetic variation was detected in the targeted genes for the different morphotypes, including non-synonymous SNPs, copy number variation and presence-absence variation. The results suggest that this broad variation in vernalization, clock and signaling genes could be a key driver of morphological differentiation for flowering-related traits in this recent allopolyploid crop species.

Predicting outcomes of transgene flow from arable crops requires a system perspective that considers ecological and evolutionary processes within a landscape context. In Europe, the arable weed Raphanus raphanistrum is a potential hybridization partner of oilseed rape, and the two species are ecologically linked through the common herbivores Meligethes spp. Observations in Switzerland show that high densities of Meligethes beetles maintained by oilseed rape crops can lead to considerable damage on R. raphanistrum. We asked how increased insect resistance in R. raphanistrum – as might be acquired through introgression from transgenic oilseed rape – would affect seed production under natural herbivore pressure. In simulation experiments, plants protected against Meligethes beetles produced about twice as many seeds as unprotected plants. All stages in the development of reproductive structures from buds to pods were negatively affected by the herbivore, with the transition from buds to flowers being the most vulnerable. We conclude that resistance to Meligethes beetles could confer a considerable selective advantage upon R. raphanistrum in regions where oilseed rape is widely grown. PMID:23467842

Monitoring studies at the landscape level are complex, expensive and difficult to conduct. Many aspects have to be considered to avoid confounding effects which is probably the reason why they are not regularly performed in the context of risk assessments of plant protection products to pollinating insects. However, if conducted appropriately their contribution is most valuable. In this paper we identify the requirements of a large-scale monitoring study for the assessment of side-effects of clothianidin seed-treated winter oilseed rape on three species of pollinating insects (Apis mellifera, Bombus terrestris and Osmia bicornis) and present how these requirements were implemented. Two circular study sites were delineated next to each other in northeast Germany and comprised almost 65 km 2 each. At the reference site, study fields were drilled with clothianidin-free OSR seeds while at the test site the oilseed rape seeds contained a coating with 10 g clothianidin and 2 g beta-cyfluthrin per kg seeds (Elado®). The comparison of environmental conditions at the study sites indicated that they are as similar as possible in terms of climate, soil, land use, history and current practice of agriculture as well as in availability of oilseed rape and non-crop bee forage. Accordingly, local environmental conditions were considered not to have had any confounding effect on the results of the monitoring of the bee species. Furthermore, the study area was found to be representative for other oilseed rape cultivation regions in Europe.

Sexual violence in South Africa is a major public health and social problem. Sexual assault or rape is a traumatic event which disrupts not only the life of the female rape victim, but also that of her male intimate partner (MIP), irrespective of whether he witnessed or was informed of the incident. The study aimed to explore the lived experiences of MIPs of female rape victims and the meaning of these experiences in the six months following the partner's rape. We conducted a longitudinal hermeneutic phenomenological study. Nine purposively sampled adult MIPs were interviewed over a period of six months. The participants were in an intimate relationship with a female rape victim prior to and immediately after the rape; their partners had been treated at a specialised centre for victims of rape and sexual assault. Four interviews were conducted with each of the nine intimate partners of female rape victims: (1) within 14 days of, (2) a month after, (3) three months after, and (4) six months after the rape. Two major themes emerged: being-in-the-world as a secondary victim of rape, and living in multiple worlds, those of their female partners, family, friends, society, employers or colleagues, professionals and the justice system. The participant's familiar world became strange and even threatening, and his relationship with his partner became uncertain. Early supportive intervention for intimate partners of female rape victims is required to prevent on-going emotional trauma and alleviate the effects of chronic post-traumatic stress disorder and suffering at intra- and interpersonal levels.

Disclosure of a rape to informal support sources (e.g., friends) is a relatively common experience, but it is not well understood. This study expands our limited knowledge of the characteristics and life experiences of disclosure recipients among a national sample of 2,000 female college students. Over 40% of respondents reported having received a rape disclosure, and more than two thirds of these recipients encouraged victims to formally report their rapes to the police or other authorities. Correlates of disclosure receipt and encouragement of reporting, including personal assault history, mental health history, and substance use, are presented and discussed. PMID:23651638

Aim To explore the short- and long-term psychological consequences of rape on women victims of rape during the 1992-1995 war against Croatia and Bosnia and Herzegovina. Methods The study included 68 women victims of rape and was conducted at the Medical Center for Human Rights, Zagreb, Croatia, from 1992 to 1995. Testimony method and a questionnaire were used to obtain the description of rapes and symptoms women suffered immediately after rape and at the time of the study, ie, 11.9 ± 2.4 months after the trauma. Structured clinical interviews were conducted to diagnose psychiatric disorders that were present at the time of study, according to the third edition of Diagnostic and Statistical Manual of Mental Disorders. Results The raped women were Croatian and Muslim (Bosniak) women, residents of Croatia and Bosnia and Herzegovina. Forty-four of them were raped more than once, 21 were raped every day during their captivity, and 18 were forced to witness rapes. Most of the rapes (n = 65) were accompanied by physical torture. The most frequent psychological symptoms felt immediately after the rape were depressiveness (n = 58), avoidance of thoughts or conversations associated with the trauma (n = 40), and suicidal ideas (n = 25). Although none of the women had a psychiatric history before the rape, at the time of study 52 suffered from depression, 51 from social phobia, 21 from posttraumatic stress disorder (PTSD), and 17 had sexual dysfunctions. These disorders were often comorbid. Out of 29 women who got pregnant after rape, 17 had artificial abortion. The decision to have an abortion was strongly predicted by suicidal thoughts and impulses (odds ratio, 25.8; 95% confidence interval, 2.53-263.2). Conclusion War-time rapes had deep immediate and long-term consequences on the mental health of women victims of rapes and their social and interpersonal functioning. PMID:16489699

Investigating the Self-Protective Potential of Immobility in Victims of Rape.

de Heer, Brooke A; Jones, Lynn C

2017-04-01

Using a nationwide sample of reported rape cases collected by the Federal Bureau of Investigation (FBI; 389 victims; 89% stranger rapes), this study investigates assumptions about self-protective behaviors for rape victims. Past research on victim resistance strategies often specifies active resistance as self-protective, inadvertently underestimating the potential for biologically based reactions, such as tonic immobility, to be self-protective as well. Results confirm that rape victims who were verbally and physically immobile during the attack were less likely to be injured and have force used against them. In addition, victims who were verbally immobile suffered a less severe attack. The results indicate that immobility may protect the victim from increased injury, force, and severity of the attack. Implications for the legal and public definition of consent are discussed.

Identification of irrigated crop types from ERTS-1 density contour maps and color infrared aerial photography. [Wyoming

The author has identified the following significant results. The crop types of a Great Plains study area were mapped from color infrared aerial photography. Each field was positively identified from field checks in the area. Enlarged (50x) density contour maps were constructed from three ERTS-1 images taken in the summer of 1973. The map interpreted from the aerial photography was compared to the density contour maps and the accuracy of the ERTS-1 density contour map interpretations were determined. Changes in the vegetation during the growing season and harvest periods were detectable on the ERTS-1 imagery. Density contouring aids in the detection of such charges.

Despite evidence suggesting that alcohol expectancies may influence people's rape perceptions, no study to date has measured context-specific expectancies comprehensively. This study represents an initial investigation of the role of sexual coercion and vulnerability alcohol expectancies in young Australian adults' rape blame attributions. Using a vignette method, it was hypothesized that participants' stronger expectancy endorsement would predict lesser perpetrator blame and greater victim blame. Participants (n = 210; 34.9% males; 18-25 years) read a hypothetical rape scenario and rated dimensions of blameworthiness attributed to the intoxicated sexual perpetrator and victim. Participants completed the Sexual Coercion and Sexual Vulnerability subscales of the Drinking Expectancy Sexual Vulnerabilities Questionnaire for the targets self, men, and women in addition to measures of traditional gender role attitudes and rape myth acceptance. Hierarchical multiple regressions revealed that, as expected, stronger sexual coercion expectancy predicted lower perpetrator blame and greater victim blame. Self-oriented expectancy predicted evaluations of the perpetrator whereas other-oriented expectancy predicted victim evaluations. These effects were robust after controlling for gender role attitudes and rape myth acceptance. Alcohol expectancies appear to be part of a network of beliefs and attitudes which perpetuate biased rape attributions and may be useful to challenge in altering rape perceptions. © The Author(s) 2014.

Asian Americans have been understudied with respect to sexuality and rape and its contributory factors. Some attitudinal research has shown that Asian American college males tend to hold more rape-supportive beliefs than their White counterparts. Generally, this research treats ethnicity as a proxy for culture rather than examining specific facets of culture per se. The current study incorporated measures of misogynistic beliefs, acculturation, and ethnic identity to investigate these ethnic differences in rape-supportive attitudes. White (n = 222) and Asian American (n = 155) college men read an acquaintance rape vignette and evaluated it on four judgments: how much they blamed the perpetrator and the victim, how credible they viewed the victim’s refusal, and to what degree they defined the event as rape. Consistent with previous research, Asian American men made more rape-supportive judgments than Whites. This relationship was partially mediated by misogynistic beliefs for all judgments except the extent to which they defined the vignette as rape. Among Asian Americans, acculturation was negatively associated with all four rape vignette judgments above and beyond generational status, and ethnic identity was positively associated with two of the four judgments above and beyond acculturation and generational status. These findings suggest that cultural constructs are relevant to understanding rape-supportive attitudes among Asian American men, and may be useful for promoting culturally enhanced theoretical models of rape and sexual assault prevention efforts, as well as a deeper understanding of cultural influences on sexuality.

2018-01-01

Thiabendazole is widely used in sclerotium blight, downy mildew and black rot prevention and treatment in rape. Accurate monitoring of thiabendazole pesticides in plants will prevent potential adverse effects to the Environment and human health. Surface Enhanced Raman Spectroscopy (SERS) is a highly sensitive fingerprint with the advantages of simple operation, convenient portability and high detection efficiency. In this paper, a rapid determination method of thiabendazole pesticides in rape was conducted combining SERS with chemometric methods. The original SERS were pretreated and the partial least squares (PLS) was applied to establish the prediction model between SERS and thiabendazole pesticides in rape. As a result, the SERS enhancing effect based on silver Nano-substrate was better than that of gold Nano-substrate, where the detection limit of thiabendazole pesticides in rape could reach 0.1 mg/L. Moreover, 782, 1007 and 1576 cm−1 could be determined as thiabendazole pesticides Raman characteristic peaks in rape. The prediction effect of thiabendazole pesticides in rape was the best (Rp2 = 0.94, RMSEP = 3.17 mg/L) after the original spectra preprocessed with 1st-Derivative, and the linear relevance between thiabendazole pesticides concentration and Raman peak intensity at 782 cm−1 was the highest (R2 = 0.91). Furthermore, five rape samples with unknown thiabendazole pesticides concentration were used to verify the accuracy and reliability of this method. It was showed that prediction relative standard deviation was 0.70–9.85%, recovery rate was 94.71–118.92% and t value was −1.489. In conclusion, the thiabendazole pesticides in rape could be rapidly and accurately detected by SERS, which was beneficial to provide a rapid, accurate and reliable scheme for the detection of pesticides residues in agriculture products.

Gender equality and women's absolute status: a test of the feminist models of rape.

PubMed

Martin, Kimberly; Vieraitis, Lynne M; Britto, Sarah

2006-04-01

Feminist theory predicts both a positive and negative relationship between gender equality and rape rates. Although liberal and radical feminist theory predicts that gender equality should ameliorate rape victimization, radical feminist theorists have argued that gender equality may increase rape in the form of male backlash. Alternatively, Marxist criminologists focus on women's absolute socioeconomic status rather than gender equality as a predictor of rape rates, whereas socialist feminists combine both radical and Marxist perspectives. This study uses factor analysis to overcome multicollinearity limitations of past studies while exploring the relationship between women's absolute and relative socioeconomic status on rape rates in major U.S. cities using 2000 census data. The findings indicate support for both the Marxist and radical feminist explanations of rape but no support for the ameliorative hypothesis. These findings support a more inclusive socialist feminist theory that takes both Marxist and radical feminist hypotheses into account.

In an effort to characterize the attitudes and characteristics of men who solicit sex, this study investigated rape myth acceptance as assessed by a modification of Burt's Rape Myth Acceptance Scale. The participants were all men who took part in the Prostitution Offender Program of British Columbia after being arrested for attempting to solicit sex from an undercover police officer. Relationships between endorsement of rape myths, other attitudes, sexual behavior, and demographic variables were examined. Results reveal that age, education, use of pornography, ideal frequency of intercourse, and believing that purchasing sex is a problem are all negatively correlated with rape myth acceptance. Positive correlations were found between rape myth acceptance and sexual conservatism, sexual violence/coercion, and social desirability. Results are discussed in terms of the association between rape myth acceptance and the violence frequently perpetrated against those working in the sex trade.

Can we use photography to estimate radiation interception by a crop canopy?

PubMed

Chakwizira, E; Meenken, E D; George, M J; Fletcher, A L

2015-03-01

Accuracy of determining radiation interception, and hence radiation use efficiency, depends on the method of measuring photosynthetically active radiation intercepted. Methods vary, from expensive instruments such as Sunfleck ceptometers to simple methods such as digital photography. However, before universal use of digital photography there is need to determine its reliability and compare it with conventional, but expensive, methods. In a series of experiments at Lincoln, New Zealand, canopy development for barley, wheat, white clover and four forage brassica species was determined using both digital photographs and Sunfleck ceptometer. Values obtained were used to calculate conversion coefficient (Kf/Ki) ratios between the two methods. Digital photographs were taken at 45° and 90° for barley, wheat and white clover and at only 90° for brassicas. There was an interaction of effects of crop and cultivar for the cereal crops. Barley closed canopies earlier than wheat, and 'Emir' barley and 'Stettler' wheat had consistently higher canopy cover than 'Golden Promise' and 'HY459', respectively. Canopy cover was consistently larger at 45° than 90° for cereals. However, for white clover, the angle of digital photography was not important. There was also an interaction between effects of species and method of determining canopy cover for brassicas. Photographs gave higher cover values than ceptometer for forage rape and turnip, but the relationship was variable for forage kale and swede. Kf/Ki ratios of 1.0-1.10 for cereals, white clover and forage rape and turnip show that digital photographs can be used to estimated radiation interception, in place of Sunfleck ceptometer, for these crops. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

A randomized between-group design was used to evaluate the efficacy of a video intervention to reduce post-traumatic stress disorder (PTSD) and other mental health problems, implemented prior to the forensic medical examination conducted within 72 h post-sexual assault. Participants were 140 female victims of sexual assault (68 video/72 nonvideo) aged 15 years or older. Assessments were targeted for 6 weeks (Time 1) and 6 months (Time 2) post-assault. At Time 1, the intervention was associated with lower scores on measures of PTSD and depression among women with a prior rape history relative to scores among women with a prior rape history in the standard care condition. At Time 2, depression scores were also lower among those with a prior rape history who were in the video relative to the standard care condition. Small effects indicating higher PTSD and Beck Anxiety Inventory (BAI) scores among women without a prior rape history in the video condition were observed at Time 1. Accelerated longitudinal growth curve analysis indicated a videoxprior rape history interaction for PTSD, yielding four patterns of symptom trajectory over time. Women with a prior rape history in the video condition generally maintained the lowest level of symptoms.

"One Problem Became Another": Disclosure of Rape-Related Pregnancy in the Abortion Care Setting.

We sought to explore the experiences of women who disclosed that their pregnancies resulted from rape in the abortion care setting, as well as the experiences of professionals involved in care of women with rape-related pregnancy. In-depth interviews were conducted with 9 patients who had terminated rape-related pregnancies and 12 professionals working in abortion care or rape crisis advocacy (5 abortion providers, 4 rape crisis center advocates, 2 social workers, and 1 clinic administrator). Transcribed interviews were coded and analyzed for themes related to the experiences of disclosing rape and the consequences of disclosure in the abortion care setting. Patients and professionals involved in care of women with rape-related pregnancy described opportunities arising from disclosure, including interpersonal (explaining abortion decision making in the context of assault, belief, and caring by providers), as well as structural opportunities (funding assistance, legal options, and mental health options). Whereas most patients did not choose to pursue all three structural opportunities, both patients and professionals emphasized the importance of offering them. The most important consequence of disclosure for patients was being believed and feeling that providers cared about them. Rape-related pregnancy disclosure in the abortion care setting can lead to opportunities for interpersonal support and open options for funding, legal recourse, and mental health care. Those working in abortion care should create environments conducive to disclosure and opportunities for rape survivors to access these additional options if they desire.

Feminist Framework Plus: Knitting Feminist Theories of Rape Etiology Into a Comprehensive Model.

PubMed

McPhail, Beverly A

2016-07-01

The radical-liberal feminist perspective on rape posits that the assault is motivated by power and control rather than sexual gratification and is a violent rather than a sexual act. However, rape is a complex act. Relying on only one early strand of feminist thought to explain the etiology of rape limits feminists' understanding of rape and the practice based upon the theory. The history of the adoption of the "power, not sex" theory is presented and the model critiqued. A more integrated model is developed and presented, the Feminist Framework Plus, which knits together five feminist theories into a comprehensive model that better explains the depth and breadth of the etiology of rape. Empirical evidence that supports each theory is detailed as well as the implications of the model on service provision, education, and advocacy. © The Author(s) 2015.

Police records of reported rape, compiled for the Federal Bureau of Investigation Uniform Crime Reports, in Houston, Texas for 1974 and 1975, were analyzed in relation to ethnicity and age of victim/offender, and time and place of occurrence. Blacks had the highest race-specific rates for both victims and offenders; the majority of all rapes were intraracial. The high-risk age group for both victims and offenders was from 20 to 24 years. Rapes increased slightly during the summer months, peaked during the hours of darkness, and were fairly evenly distributed among the days of the week. The weekend calculated as from 4:00 pm Friday to 8:00 am Monday accounted for 43.6 per cent of all rape occurrences. The majority of rape events involved the use of a lethal weapon and took place in a residence. PMID:434279

Increasing in-stream nitrogen concentrations under different bioenergy crop management practices in central Germany

NASA Astrophysics Data System (ADS)

Jomaa, Seifeddine; Thraen, Daniela; Rode, Michael

2015-04-01

Understanding how nitrogen fluxes respond to changes in land use and agriculture practices is crucial for improving instream water quality prediction. In central Germany, expansion of bioenergy crops such as maize and rape for ethanol production during the last decade led to increasing of fertilizer application rates. To examine the effect of these changes, surface water quality of a drinking water reservoir catchment was investigated for more than 30 years. The Weida catchment (99.5 km2) is part of the Elbe river basin and has a share of 67% agricultural land use with significant changes in agricultural practices within the investigation period. For the period 2004-2012, the share of maize and rape has been increased by 52% and 20%, respectively, for enhancing bioenergy production. To achieve our gaols, the semi-distributed hydrological water quality HYPE (Hydrological Predictions for the Environment) model was calibrated for discharge and inorganic nitrogen concentrations (IN) during the period 1997-2000.The model was validated successfully (with lowest performance of NSE = 0.78 and PBIAS = 3.74% for discharge) for three different periods 1983-1987, 1989-1996 and 2000-2003, which are charaterized by different fertilizer application rates. Results showed that the HYPE model reproduced reasonably well discharge and IN daily loads (with lowest NSE = 0.64 for IN-load). In addition, the HYPE model was evaluated successfully to predict the discharge and IN concentrations for the period 2004-2012, where detailed input data in terms of crops management (field-specific survey) have been considered. Land use and crop rotations scenarios, with high hypothetical percentage of acceptance by the farmers, revealed that continuous conversion of agricultural land into bioenergy crops, will most likely, lead to an enrichment of in-stream nitrogen, especially after spring storms.

The Role of the New "Date Rape Drugs" in Attributions about Date Rape

Battles on women's bodies: war, rape and traumatisation in eastern Democratic Republic of Congo.

Trenholm, J E; Olsson, P; Ahlberg, B M

2011-01-01

Rape has been used as a weapon in the conflict in eastern Democratic Republic of Congo (DRC) in unprecedented ways. Research into the phenomenon of war-rape is limited, particularly in this context. The aim of this study was to explore perceptions of local leaders in eastern DRC concerning rape and raped women in the war context. Local leaders were chosen for their ability to both reflect and influence their constituencies. Interviews were conducted with 10 local leaders and transcripts subjected to qualitative content analysis. The study suggests that mass raping and the methods of perpetration created a chaos effectively destroying communities and the entire society and that humanitarian aid was often inappropriate. Furthermore, an exclusive focus on raped women missed the extent of traumatisation entire communities suffered. More significantly, the lack of political will, corruption, greed and inappropriate aid creates a tangled web serving to intensify the war. This complexity has implications for humanitarian interventions including public health.

Labeling Sexual Victimization Experiences: The Role of Sexism, Rape Myth Acceptance, and Tolerance for Sexual Harassment.

PubMed

LeMaire, Kelly L; Oswald, Debra L; Russell, Brenda L

2016-01-01

This study investigated whether attitudinal variables, such as benevolent and hostile sexism toward men and women, female rape myth acceptance, and tolerance of sexual harassment are related to women labeling their sexual assault experiences as rape. In a sample of 276 female college students, 71 (25.7%) reported at least one experience that met the operational definition of rape, although only 46.5% of those women labeled the experience "rape." Benevolent sexism, tolerance of sexual harassment, and rape myth acceptance, but not hostile sexism, significantly predicted labeling of previous sexual assault experiences by the victims. Specifically, those with more benevolent sexist attitudes toward both men and women, greater rape myth acceptance, and more tolerant attitudes of sexual harassment were less likely to label their past sexual assault experience as rape. The results are discussed for their clinical and theoretical implications.

We sought to estimate the prevalence of rape-related pregnancy as an indication for abortion at two public Chicago facilities and to describe demographic and clinical correlates of women who terminated rape-related pregnancies. We performed a cross-sectional study of women obtaining abortion at the Center for Reproductive Health (CRH) at University of Illinois Health Sciences Center and Reproductive Health Services (RHS) at John H. Stroger, Jr. Hospital between August 2009 and August 2013. Gestational age limits at CRH and RHS were 23+6 and 13+6weeks, respectively. We estimated the prevalence of rape-related pregnancy based on billing code (CRH) or data from an administrative database (RHS), and examined relationships between rape-related pregnancy and demographic and clinical variables. Included were 19,465 visits for abortion. The majority of patients were Black (85.6%). Prevalence of abortion for rape-related pregnancy was 1.9%, and was higher at CRH (6.9%) than RHS (1.5%). Later gestational age was associated with abortion for rape-related pregnancy (median 12days, p<.001). Younger age and Black race were associated with abortion for rape-related pregnancy at CRH only (p<.001 for both). Chlamydia and gonorrhea infection were no more prevalent among women terminating rape-related pregnancy than among those terminating for other indications. Rape-related pregnancy as an indication for abortion had a low, but clinically significant prevalence at two urban Chicago family planning centers. Later gestational age was associated with abortion for rape-related pregnancy. Rape-related pregnancy may occur with higher prevalence among some subgroups of women seeking abortion than others. Efforts to address rape-related pregnancy in the abortion care setting are needed. Copyright © 2015 Elsevier Inc. All rights reserved.

Responding to the rape of Indonesian Chinese women and girls.

PubMed

1998-09-01

In May 1998, 168 women and girls were gang-raped during the Jakarta riots. In response, the Humanity Volunteer Team, a nongovernmental organization, set up a Violence Against Women Division. This group is composed of 400 people from diverse backgrounds and ethnic groups who undergo training and then volunteer their services to provide psychological and physical support to the affected victims and their families and to investigate the crimes. The volunteers have adopted a holistic approach and work with the cooperation of private hospitals. They accomplish their work in a climate of fear because it is considered subversive simply to bring this issue to light. Rape survivors and their families, as well as medical staff and volunteers, have been intimidated to the point that many rape survivors have traveled abroad to seek treatment. Long-term prevention strategies should include 1) a state apology to rape survivors and their communities, 2) an independent investigation to expose the perpetrators, and 3) the protection of the civil rights of the minority Chinese in Indonesia.

A novel British research program called PROSAMO - Planned Release of Selected and Modified Organisms - has just produced its first batch of results on the ecological behavior of a genetically manipulated variety of oil seed rape (known to Americans as canola). As expected, the preliminary data indicate that these plants do not outgrow their competitors in the wild, nor is there any evidence that they pass on their foreign genes to other species. PROSAMO is moving on to test other crops with other foreign genes. If these results are as reassuring, scientists around the world will have solid evidencemore » with which to soothe fears.« less

Rape myth acceptance among Korean college students: the roles of gender, attitudes toward women, and sexual double standard.

PubMed

Lee, Joohee; Kim, Jinseok; Lim, Hyunsung

2010-07-01

The purpose of the current study was to examine factors that influence rape myths among Korean college students. This study was particularly interested in the ways in which attitudes toward women and sexual double standard affect the relationship between gender and rape myths. Although the incidence of rape is a common concern in many current societies, within each society, the specific components of rape myths reflect the cultural values and norms of that particular society. A sample of 327 college students in South Korea completed the Korean Rape Myth Acceptance Scale-Revised, the Attitudes Toward Women Scale, and the Sexual Double Standard Scale. Structural equation modeling (SEM) was used to test hypothesized models. Results revealed that in three of the four models, rape survivor myths, rape perpetrator myths, and myths about the impact of rape, attitudes toward women were a more important predictor of rape myths than gender or sexual double standard. In the rape spontaneity myths model, on the other hand, sexual double standard was a more important predictor than gender or attitudes toward women. This study provides valuable information that can be useful in developing culturally specific rape prevention and victim intervention programs.

Cellulose accessibility and microbial community in solid state anaerobic digestion of rape straw.

2017-01-01

Solid state anaerobic digestion (SSAD) with leachate recirculation is an appropriate method for the valorization of agriculture residues. Rape straw is a massively produced residue with considerable biochemical methane potential, but its degradation in SSAD remains poorly understood. A thorough study was conducted to understand the performance of rape straw as feedstock for laboratory solid state anaerobic digesters. We investigated the methane production kinetics of rape straw in relation to cellulose accessibility to cellulase and the microbial community. Improving cellulose accessibility through milling had a positive influence on both the methane production rate and methane yield. The SSAD of rape straw reached 60% of its BMP in a 40-day pilot-scale test. Distinct bacterial communities were observed in digested rape straw and leachate, with Bacteroidales and Sphingobacteriales as the most abundant orders, respectively. Archaeal populations showed no phase preference and increased chronologically. Copyright © 2016 Elsevier Ltd. All rights reserved.

Impact of rapeseed cropping on the soil carbon balance

Moffat, Antje Maria; Herbst, Mathias; Huth, Vytas; Andres, Monique; Augustin, Jürgen

2015-04-01

Winter oilseed rape is the dominant biofuel crop in the young moraine landscape in Northern Germany. Since the cultivation of biofuel crops requires sustainability compared to fossil fuels by law, detailed knowledge about their green house gas (GHG) balance is necessary. The soil carbon balance is one of the key contributors to the total GHG balance and also very important for the assessment of soil fertility. However, the knowledge about the impact of different management practices on the soil carbon balance is very limited up to now. Therefore, we investigated the carbon fluxes of winter oilseed rape at field plots near Dedelow/Uckermark in NE Germany with different treatments of fertilization (mineral versus organic) and tillage (no-till and mulch-till versus ploughing). The dynamics of the carbon fluxes are mainly driven by the current climatic conditions but the overall response depends strongly on the ecosystem state (with its physiological and microbiological properties) which is affected by management. To get the full carbon flux dynamics but also the impact of the different management practices, two different approaches were used: The eddy covariance technique to get continuous fluxes throughout the year and the manual chamber technique to detect flux differences between specific management practices. The manual chamber measurements were conducted four-weekly as all-day campaigns using a flow-through non-steady-state closed chamber system. The fluxes in-between campaigns were gap-filled based on functional relationships with soil and air temperature (for the ecosystem respiration) and photosynthetic active radiation (for the gross primary production). All results presented refer to the cropping season 2012-2013. The combination of the two measurement techniques allows the evaluation of chamber fluxes including an independent estimate of the error on the overall balances. Despite the considerable errors, there are significant differences in the soil carbon

Factors that affect college students' perceptions of rape: what is the role of gender and other situational factors?

PubMed

Vandiver, Donna M; Dupalo, Jessica Rager

2013-05-01

Prior research has shown that various situational factors and behaviors can affect one's perception of whether a rape has occurred. Moreover, some hold false beliefs about rape. This can also affect one's perception of ambiguous situations. This study included the administration of a survey to 584 college students; the survey examined the prevalence of rape myths and responses to vignettes of potential rape scenarios. It was found that although the majority of this sample did not support rape myths, male students were significantly more likely than female students to support rape myths. Furthermore, approximately 20% of students did support one subscale of the rape myth scale: He didn't mean to [commit rape]. The results also revealed an interaction effect between the observer's sex and the victim's sex, suggesting a complex gender relationship.

The cultural context of nondisclosure of alcohol-involved acquaintance rape among Asian American college women: a qualitative study.

PubMed

Koo, Kelly H; Nguyen, Hong V; Andrasik, Michele P; George, William H

2015-01-01

With high college enrollment and increasing alcohol use, Asian American (AA) college women may be at particular risk for experiencing alcohol-involved acquaintance rape. Although AA women have expressed the weakest intentions to report rape when compared to other ethnic groups, cultural factors influencing these intentions remain unexamined. Guided by grounded theory, 17 self-identified AA college women were interviewed about how the average AA college woman would respond to an alcohol-involved acquaintance rape. Despite awareness of benefits of disclosing rape, participants emphasized that nondisclosure would be the normative response. Three themes emerged from participants: institutional, sociocultural, and psychological contexts of nondisclosure. At an institutional level, nondisclosure referenced mental health and police services, which included Asian stereotypes and mistrust of police. Within a sociocultural context, rape nondisclosure focused on negative consequences on relationships with parents and, to a lesser extent, on friendships. Emotional avoidance and not labeling an acquaintance rape as rape were psychological strategies for rape nondisclosure. Participant's conceptualizations of mental and physical health concerns, specifically post-rape concerns, were framed within sociocultural/macrostructural contexts and may not match that of the more individualistic U.S. mainstream conceptualizations of health. Culturally sensitive rape education may be more effective in increasing rape prevention and support.

Judgments toward male and transgendered victims in a depicted stranger rape.

PubMed

Davies, Michelle; Hudson, Jenefer

2011-01-01

There has been an increasing amount of research interest into perceptions of male rape in recent years. However, no research has assessed how people react when a transgendered person is raped. The aim of this study was to investigate the effects of transgendered status and sexuality on victim blame and perceived severity in a depicted rape scenario. The sexuality of the victim was manipulated to include a heterosexual, homosexual, cross-dresser, female-to-male transsexual, and male-to-female transsexual. It was predicted that the heterosexual victims would be judged the most positively and that heterosexual male participants would make the most anti-victim judgments. One hundred thirty-three lesbian, gay male, and heterosexual members of the general population read a scenario depicting a rape and then completed a questionnaire measuring victim blame and perceived severity of the assault. Results conformed to the predictions. Results are discussed in relation to traditional gender roles and homophobia.

An examination of the disparity between self-identified versus legally identified rape victimization: A pilot study.

PubMed

Marsil, Dorothy F; McNamara, Corinne

2016-07-01

Researchers compared rape victimization based on self-identification to the current federal legal definition in a pilot study of college students. The sample was comprised of 1,648 (69.8% female; 30.2% male) college students who completed the Sexual Experiences Survey-Short Form Victimization (SES-SFV) online. Based on the current legal definition of rape, 9.4% (11.1% female; 5.2% male) of students had been raped since being enrolled, but only 2.9% of students self-identified as being raped. Moreover, 15.1% of students reported ever being raped, with females acknowledging higher rates (19.7%) than males (4.3%). Rape continues to be a major issue for colleges and universities. A serious concern is the disparity between the number of those who met the behavioral criteria for rape victimization based on the current legal definition, but who did not self-identify as a victim. Universities must address this disparity by using multiple measures to assess the prevalence of sexual violence on campus.

Crop responses to elevated CO2 and interactions with H2O, N, and temperature.

Kimball, Bruce A

2016-06-01

About twenty-seven years ago, free-air CO2 enrichment (FACE) technology was developed that enabled the air above open-field plots to be enriched with CO2 for entire growing seasons. Since then, FACE experiments have been conducted on cotton, wheat, ryegrass, clover, potato, grape, rice, barley, sugar beet, soybean, cassava, rape, mustard, coffee (C3 crops), and sorghum and maize (C4 crops). Elevated CO2 (550ppm from an ambient concentration of about 353ppm in 1990) decreased evapotranspiration about 10% on average and increased canopy temperatures about 0.7°C. Biomass and yield were increased by FACE in all C3 species, but not in C4 species except when water was limiting. Yields of C3 grain crops were increased on average about 19%.

Using colposcopy in the rape exam: health care, forensic, and criminal justice issues.

PubMed

Sommers, Marilyn Sawyer; Fisher, Bonnie S; Karjane, Heather M

2005-01-01

In the setting of a forensic examination following rape, colposcopy allows practitioners to identify and photograph genital injury not readily visible to the unaided eye, thereby clarifying the location and extent of injury as well as providing evidence for court proceedings. Since the 1980s, the technique once reserved for victims of child abuse has been used across the lifespan and has been shown to identify genital injury in up to 87% of women who have been raped. The role of colposcopic findings as evidence in court testimony, however, remains controversial. This paper explores the history of colposcopy in the rape exam and describes the epidemiology of genital injury in consensual sex as well as rape.

Drug-facilitated sexual assault ('date rape').

PubMed

Schwartz, R H; Milteer, R; LeBeau, M A

2000-06-01

In the past few years, drug-facilitated sexual assaults have received widespread media coverage. In addition to alcohol, the most frequently used date-rape drug, flunitrazepam (Rohypnol), a fast-acting benzodiazepine, and gamma-hydroxybutyrate (GHB) and its congeners are among the most popular drugs used for this purpose. The latter drug is easily procured at some gymnasiums, popular bars, discos, and rave clubs, as well as over the Internet. Perpetrators choose these drugs because they act rapidly, produce disinhibition and relaxation of voluntary muscles, and cause the victim to have lasting anterograde amnesia for events that occur under the influence of the drug. Alcoholic beverages potentiate the drug effects. We review several date-rape drugs, provide information on laboratory testing for them, and offer guidelines for preventing drug-facilitated sexual assault.

Examining the Psychological Effect of Rape Acknowledgment: The Interaction of Acknowledgment Status and Ambivalent Sexism.

2017-07-01

Although the majority of rape survivors do not label their experiences as rape (i.e., unacknowledged rape), the literature is mixed in terms of how this affects survivors' psychological functioning. To elucidate the discrepancies, the present study examined the interaction between rape acknowledgement and ambivalent sexism in relation to depression and posttraumatic stress disorder (PTSD) symptoms. The analyzed sample included 128 female rape survivors who were drawn from a larger college sample of 1,595 participants. The participants completed measures of sexual assault experiences, ambivalent sexism, and depression and PTSD symptoms. The results supported a significant interaction between acknowledgement status and benevolent sexism in relation to both depression and PTSD symptoms. Conversely, the present study failed to find support for an interaction between acknowledgment status and hostile sexism. The clinical implications suggest that rather than seeing acknowledging rape as essential to the recovery process, clinicians should assess for and take into account other factors that may contribute to psychological functioning. Additionally, the findings support that more complex models of trauma recovery should be investigated with the goal of working toward a more comprehensive understanding of the longitudinal process of rape acknowledgment. © 2016 Wiley Periodicals, Inc.

Effects of break crops, and of wheat volunteers growing in break crops or in set-aside or conservation covers, all following crops of winter wheat, on the development of take-all (Gaeumannomyces graminis var. tritici) in succeeding crops of winter wheat

PubMed Central

Jenkyn, JF; Gutteridge, RJ; White, RP

2014-01-01

Experiments on the Rothamsted and Woburn Experimental Farms studied the effects on take-all of different break crops and of set-aside/conservation covers that interrupted sequences of winter wheat. There was no evidence for different effects on take-all of the break crops per se but the presence of volunteers, in crops of oilseed rape, increased the amounts of take-all in the following wheat. Severity of take-all was closely related to the numbers of volunteers in the preceding break crops and covers, and was affected by the date of their destruction. Early destruction of set-aside/conservation covers was usually effective in preventing damaging take-all in the following wheat except, sometimes, when populations of volunteers were very large. The experiments were not designed to test the effects of sowing dates but different amounts of take-all in the first wheats after breaks or covers apparently affected the severity of take-all in the following (second) wheats only where the latter were relatively late sown. In earlier-sown second wheats, take-all was consistently severe and unrelated to the severity of the disease in the preceding (first) wheats. Results from two very simple experiments suggested that substituting set-aside/conservation covers for winter wheat, for 1 year only, did not seriously interfere with the development of take-all disease or with the development or maintenance of take-all decline (TAD). With further research, it might be possible for growers wishing to exploit TAD to incorporate set-aside/conservation covers into their cropping strategies, and especially to avoid the worst effects of the disease on grain yield during the early stages of epidemics.

Background Delayed disclosure of rape has been associated with impaired mental health; it is, therefore, important to understand which factors are associated with disclosure latency. The purpose of this study was to compare various demographics, post-rape characteristics, and psychological functioning of early and delayed disclosers (i.e., more than 1-week post-rape) among rape victims, and to determine predictors for delayed disclosure. Methods Data were collected using a structured interview and validated questionnaires in a sample of 323 help-seeking female adolescents and young adults (12–25 years), who were victimized by rape, but had no reported prior chronic child sexual abuse. Results In 59% of the cases, disclosure occurred within 1 week. Delayed disclosers were less likely to use medical services and to report to the police than early disclosers. No significant differences were found between delayed and early disclosers in psychological functioning and time to seek professional help. The combination of age category 12–17 years [odds ratio (OR) 2.05, confidence intervals (CI) 1.13–3.73], penetration (OR 2.36, CI 1.25–4.46), and closeness to assailant (OR 2.64, CI 1.52–4.60) contributed significantly to the prediction of delayed disclosure. Conclusion The results point to the need of targeted interventions that specifically encourage rape victims to disclose early, thereby increasing options for access to health and police services.

Sexual assaults against women are a global health crisis, with alarmingly high rates in South Africa. However, we know very little about the circumstances and the aftermath of these experiences. Further, there is limited information about how factors specific to the rape (e.g., fighting back) versus those that are specific to the individual-and potentially modifiable-influence mental health outcomes. This study examined how situational characteristics of rape as well as individual and situational factors confer risk for symptoms of depression, posttraumatic stress disorder (PTSD), and dysfunctional sexual behavior at 12-month follow-up. Two hundred nine (N = 209) South African women were recruited from rural rape clinics in the Limpopo Province (LP) and North West Province (NWP) of South Africa. Interviews were conducted at baseline (within 6 months of the rape incident) and at 6 and 12 months by trained staff at the clinics in English or the women's native languages. Women were interviewed after services were provided in a private room. One hundred thirty-two (n = 132) women were lost to follow-up at 12 months, resulting in 77 women with interview data for all time points. Undermining by the survivor's social support system and an increased belief in myths about rape were associated with increased dysfunctional sexual practices and symptoms of depression. These findings demonstrate the need for interventions that address the most pervasive effects of rape over time. These behaviors can increase risks for revictimization and reduce psychological well-being in the aftermath of rape. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

2016-03-01

Seed samples of some rape and canola cultivars were analysed for oil content, fatty acid and tocopherol profiles. Gas liquid chromotography and high performance liquid chromotography were used for fatty acid and tocopherol analysis, respectively. The oil contents of rape and canola seeds varied between 30.6% and 48.3% of the dry weight (p<0.05). The oil contents of rapeseeds were found to be high compared with canola seed oils. The main fatty acids in the oils are oleic (56.80-64.92%), linoleic (17.11-20.92%) and palmitic (4.18-5.01%) acids. A few types of tocopherols were found in rape and canola oils in various amounts: α-tocopherol, γ-tocopherol, δ-tocopherol, β-tocopherol and α-tocotrienol. The major tocopherol in the seed oils of rape and canola cultivars were α-tocopherol (13.22-40.01%) and γ-tocopherol (33.64-51.53%) accompanied by α-T3 (0.0-1.34%) and δ-tocopherol (0.25-1.86%) (p<0.05). As a result, the present study shows that oil, fatty acid and tocopherol contents differ significantly among the cultivars.

Gender Inequitable Masculinity and Sexual Entitlement in Rape Perpetration South Africa: Findings of a Cross-Sectional Study

2011-01-01

Objective To describe the prevalence and patterns of rape perpetration in a randomly selected sample of men from the general adult population, to explore factors associated with rape and to describe how men explained their acts of rape. Design Cross-sectional household study with a two- stage randomly selected sample of men. Methods 1737 South African men aged 18–49 completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. Multivariable logistic regression models were built to identify factors associated with rape perpetration. Results In all 27.6% (466/1686) of men had raped a woman, whether an intimate partner, stranger or acquaintance, and whether perpetrated alone or with accomplices, and 4.7% had raped in the last 12 months. First rapes for 75% were perpetrated before age 20, and 53.9% (251) of those raping, did so on multiple occasions. The logistic regression model showed that having raped was associated with greater adversity in childhood, having been raped by a man and higher maternal education. It was associated with less equitable views on gender relations, having had more partners, and many more gender inequitable practices including transactional sex and physical partner violence. Also drug use, gang membership and a higher score on the dimensions of psychopathic personality, namely blame externalisation and Machiavellian egocentricity. Asked about why they did it, the most common motivations stemmed from ideas of sexual entitlement. Conclusions Perpetration of rape is so prevalent that population-based measures of prevention are essential to complement criminal justice system responses. Our findings show the importance of measures to build gender equity and change dominant ideas of masculinity and gender relations as part of rape prevention. Reducing men's exposure to trauma in childhood is also critically important. PMID:22216324

Objective Rape is a well-established risk factor for mental health disorders such as posttraumatic stress disorder (PTSD) and depression. However, most studies have focused on forcible rape tactics and have not distinguished these from tactics that involve drug or alcohol intoxication. Our aim was to examine correlates of PTSD and depression in a community sample of women, with particular emphasis on evaluating the unique effects of lifetime exposure to three specific rape tactics. Methods A nationally representative sample of 3,001 non-institutionalized, civilian, English or Spanish speaking women (aged 18–86 years) participated in a structured telephone interview by use of Computer-Assisted Telephone Interviewing technology. Results Multivariable models showed that history of drug or alcohol facilitated rape tactics (OR = 1.87, p< .05) and history of forcible rape tactics (OR = 3.46, p<.001) were associated with PTSD. History of forcible rape was associated with depression (OR = 3.65, p<.001). Forcible rape tactics were associated with a number of factors that may have contributed to their stronger association with mental health outcomes, including force, injury, lower income, revictimization history, and labeling the event as rape. Conclusions Our results underscore the importance of using a behaviorally specific assessment of rape history, as rape tactic and multiple rape history differentially predicted psychopathology outcomes. The association between drug or alcohol facilitated rape tactics and PTSD suggests that these are important rape tactics to include in assessments and future studies. PMID:20100896

Cumulative impact of GM herbicide-tolerant cropping on arable plants assessed through species-based and functional taxonomies.

In a gradualist approach to the introduction of crop biotechnology, the findings of experimentation at one scale are used to predict the outcome of moving to a higher scale of deployment. Movement through scales had occurred for certain genetically modified herbicide-tolerant (GMHT) crops in the UK as far as large-scale field trials. However, the land area occupied by these trials was still <1% of the area occupied by the respective non-GM crops. Some means is needed to predict the direction and size of the effect of increasing the area of GMHT cropping on ecological variables such as the diversity among species and trophic interactions. Species-accumulation curves are examined here as a method of indicating regional-scale impacts on botanical diversity from multiple field experiments. Data were used from experiments on the effect of (GMHT) crops and non-GM, or conventional, comparators in fields sown with four crop types (beet, maize, spring and winter oilseed rape) at a total of 250 sites in the UK between 2000 and 2003. Indices of biodiversity were measured in a split-field design comparing GMHT with the farmers' usual weed management. In the original analyses based on the means at site level, effects were detected on the mass of weeds in the three spring crops and the proportion of broadleaf and grass weeds in winter oilseed rape, but not on indices of plant species diversity. To explore the links between site means and total taxa, accumulation curves were constructed based on the number of plant species (a pool of around 250 species in total) and the number of plant functional types (24), inferred from the general life-history characteristics of a species. Species accumulation differed between GMHT and conventional treatments in direction and size, depending on the type of crop and its conventional management. Differences were mostly in the asymptote of the curve, indicative of the maximum number of species found in a treatment, rather than the steepness of

Approximately 15% to 20% of women have been victims of rape and close to a third report current rape-related PTSD or clinically significant depression or anxiety. Unfortunately, very few distressed rape victims seek formal help. This suggests a need to develop alternative ways to assist the many distressed victims of sexual violence. Online treatment programs represent a potentially important alternative strategy for reaching such individuals. The current paper describes a pilot evaluation of an online, therapist-facilitated, self-paced cognitive behavioral program for rape victims. Five college women with current rape-related PTSD were recruited to complete the From Survivor to Thriver (S to T) program in a lab setting over the course of 7 weeks. After completing the program, 4 participants reported clinically significant reductions in PTSD symptoms and no longer met criteria for PTSD. All participants reported clinically significant reductions in vulnerability fears and 4 reported significant reductions in negative trauma-related cognitions. Implications of the results for further development of the S to T program and how clinicians could utilize this program in treating rape-related PTSD are discussed. PMID:24009410

Measurement Matters: Comparing Old and New Definitions of Rape in Federal Statistical Reporting.

National statistics on the incidence of rape play an important role in the work of policymakers and academics. The Uniform Crime Reports (UCR) have provided some of the most widely used and influential statistics on the incidence of rape across the United States over the past 80 years. The definition of rape used by UCR changed in 2012 to include substantially more types of sexual assault. This article draws on 20 years of data from the National Incident-Based Reporting System to describe the impact this definitional change will have on estimates of the incidence of rape and trends over time. Drawing on time series as well as panel random effects methodologies, we show that 40% of sexual assaults have been excluded by the prior definition and that the magnitude of this error has grown over time. However, the overall trend in rape over time (year-to-year change) was not substantially different when comparing events meeting the prior definition and the subgroups of sexual assault that will now be counted. © The Author(s) 2014.

Weather Effects on Crop Diseases in Eastern Germany

2017-04-01

Since the 1970s there are several long-term monitoring programmes for plant diseases and pests in Germany. Within the framework of a national research project, some otherwise confidential databases comprising 77 111 samples from numerous sites accross Eastern Germany could be accessed and analysed. The pest data covered leaf rust (Puccinia triticina) and powdery mildew (Blumeria graminis) in winter wheat, aphids (Aphididae, four genera) on wheat and other cereal crops, late blight (Phytophthora infestans) in potatoes, and pollen beetles (Brassicogethes aeneus) on rape. These data were complemented by daily weather observations from the German Weather Service (DWD). In a first step, Pearson correlations between weather variables and pest frequencies were calculated for seasonal time periods of different start months and durations and ordered into so-called correlograms. This revealed principal weather effects on disease spread - e. g. that wind is favourable for mildew throughout the year or that rape pollen beetles like it warm, but not during wintertime. Secondly, the pest frequency samples were found to resemble gamma distributions, and a generalised linear model was fitted to describe their parameter shift depending on end-of-winter temperatures for aphids on cereals. The method clearly shows potential for systematic pest risk assessments regarding climate change.

Gender, Sexual Orientation, and Rape Myth Acceptance: Preliminary Findings From a Sample of Primarily LGBQ-Identified Survey Respondents.

PubMed

Schulze, Corina; Koon-Magnin, Sarah

2017-02-01

This study is among the first to examine the relationship between sexual orientation and rape myth adherence using a nationwide survey of primarily lesbian, gay, bisexual, and queer (LGBQ) respondents (n = 184). The more established Illinois Rape Myth Acceptance Scale and a modified Male Rape Survey serve as the primary instruments to test both rape myth adherence and instrument-appropriateness. Results suggest that respondents were most likely to support myths that discredit sexual assault allegations or excuse rape as a biological imperative and least likely to support myths related to physical resistance. Consistent with previous work, men exhibited higher levels of rape myth adherence than women. Regarding sexual orientation, respondents who identified as queer consistently exhibited lower levels of rape myth adherence than respondents who identified as gay.

Reading Playboy for the articles: the graying of rape myths in black and white text, 1953 to 2003.

PubMed

Kettrey, Heather Hensman

2013-08-01

This longitudinal investigation analyzes the manner in which rape myths are conveyed through textual material published in Playboy. Results indicate that Playboy (a) portrays rape as a gender-neutral issue, ignoring patriarchal roots of sexual violence against women, and (b) promulgates ambiguous discourse, which is equally likely to endorse and refute rape myths. Interestingly, readers' contributions are most often the source of refutations of rape myths. Overall, findings suggest that little progress has been made over time in deconstructing rape myths promulgated to men, as this particular men's publication has consistently painted a gray picture in which refutations have remained unsuccessful in disempowering rape myths.

Rape disclosure: the interplay of gender, culture and kinship in contemporary Vietnam.

PubMed

Huong, Nguyen Thu

2012-01-01

This paper examines the social management of rape within kin groups in contemporary Vietnam, with a particular focus on the decision whether or not to seek legal redress. Post-rape management entails negotiations among families on matters such as apology and compensation before a decision is made about whether to report the incident to the authorities. By drawing on an ethnographic study of a limited number of respondents, this paper highlights how rape disclosure is often bound up with notions of family honour, with assumptions about kinship, gender relations, social belonging and shared responsibility in a collective society such as Vietnam.

The Exploitive Mating Strategy of the Dark Triad Traits: Tests of Rape-Enabling Attitudes.

PubMed

Jonason, Peter K; Girgis, Mary; Milne-Home, Josephine

2017-04-01

The Dark Triad traits have been repeatedly labeled as facilitating an exploitive mating strategy. However, various researchers have repeatedly conflated short-term mating or casual sex with an exploitive mating strategy. In this study using Mechanical Turk participants (N = 252; 142 men, 110 women), we provided a better test of just how sexually exploitive those high on the Dark Triad traits might be by examining how the traits related to rape-enabling attitudes. We examined how each trait may facilitate rape, whether these associations were robust to partialing the variance associated with the Big Five traits and similar in men and women, and showed that one reason why men may be more likely to rape than women is they are characterized by the Dark Triad traits more than women are. In so doing, we test the confluence model of rape that asserts that personality traits similar to the Dark Triad traits act as one pathway to rape.

Consequences of gene flow between oilseed rape (Brassica napus) and its relatives.

2013-10-01

Numerous studies have focused on the probability of occurrence of gene flow between transgenic crops and their wild relatives and the likelihood of transgene escape, which should be assessed before the commercial release of transgenic crops. This review paper focuses on this issue for oilseed rape, Brassica napus L., a species that produces huge numbers of pollen grains and seeds. We analyze separately the distinct steps of gene flow: (1) pollen and seeds as vectors of gene flow; (2) spontaneous hybridization; (3) hybrid behavior, fitness cost due to hybridization and mechanisms of introgression; (4) and fitness benefit due to transgenes (e.g. herbicide resistance and Bt toxin). Some physical, biological and molecular means of transgene containment are also described. Although hybrids and first generation progeny are difficult to identify in fields and non-crop habitats, the literature shows that transgenes could readily introgress into Brassica rapa, Brassica juncea and Brassica oleracea, while introgression is expected to be rare with Brassica nigra, Hirschfeldia incana and Raphanus raphanistrum. The hybrids grow well but produce less seed than their wild parent. The difference declines with increasing generations. However, there is large uncertainty about the evolution of chromosome numbers and recombination, and many parameters of life history traits of hybrids and progeny are not determined with satisfactory confidence to build generic models capable to really cover the wide diversity of situations. We show that more studies are needed to strengthen and organize biological knowledge, which is a necessary prerequisite for model simulations to assess the practical and evolutionary outputs of introgression, and to provide guidelines for gene flow management.

Long-Term Monitoring of Field Trial Sites with Genetically Modified Oilseed Rape (Brassica napus L.) in Saxony-Anhalt, Germany. Fifteen Years Persistence to Date but No Spatial Dispersion

PubMed Central

Belter, Anke

2016-01-01

Oilseed rape is known to persist in arable fields because of its ability to develop secondary seed dormancy in certain agronomic and environmental conditions. If conditions change, rapeseeds are able to germinate up to 10 years later to build volunteers in ensuing crops. Extrapolations of experimental data acted on the assumption of persistence periods for more than 20 years after last harvest of rapeseed. Genetically-modified oilseed rape—cultivated widely in Northern America since 1996—is assumed not to differ from its conventional form in this property. Here, experimental data are reported from official monitoring activities that verify these assumptions. At two former field trial sites in Saxony-Anhalt genetically-modified herbicide-resistant oilseed rape volunteers are found up to fifteen years after harvest. Nevertheless, spatial dispersion or establishment of GM plants outside of the field sites was not observed within this period. PMID:26784233

[Medicolegal considerations about rape as a reason to decriminalize abortion].

PubMed

González-Wilhelm, Leonardo; Moreno, Leonardo; Carnevali, Raúl

2016-06-01

The Chilean senate is discussing a proposal to decriminalize abortion in 3 causals. One of these is when the pregnancy occurs as a result of a rape. To be legally able to perform the abortion in this circumstance, a health care team must confirm the occurrence of the facts constituting the offence. Regardless of the patient’s will, the accusation will be reported to the justice. In our view, in its current status the proposed rule does not consider certain medicolegal and procedural topics. Those flaws may determine in certain scenarios critical problems, such as: a) a wrongful conviction as a consequence of a false allegation of rape; (b) some pregnant due to a rape will not have access to the abortion procedure; (c) some accusations of rape will not be accredited nor criminally sanctioned. Employing a fictional case, we illustrate how those scenarios can actually be seen in practice. We also emphasize the difficulties and limitations that the health care team will encounter if the project is approved under the current conditions. Finally, we encourage the professional societies implicated in the theme to contribute in the legislatorial debate. Therefore, we give a set of proposals aimed to improve the bill before it may be enacted as a law.

Farm Crops Depredation by European Bison ( Bison bonasus) in the Vicinity of Forest Habitats in Northeastern Poland

NASA Astrophysics Data System (ADS)

Hofman-Kamińska, Emilia; Kowalczyk, Rafał

2012-10-01

European bison, the largest mammal in Europe, after being exterminated in the wild and then restored during the 20th century is still listed by the International Union for Conservation of Nature (IUCN Red List of Threatened Species) as a species vulnerable to extinction. However, the increasing number of European bison, through creation of new and expansion of existing populations strongly increases the risk of human-bison conflict in the near future. We analyzed the depredation of farm crops by bison and the factors influencing the level of damage in the vicinity of two forest areas inhabited by bison in northeastern Poland. Between 2000 and 2010, the total cost of compensation was € 196,200. The level of damage and amount of compensation was increasing from year to year in both forests and correlated with the number of bison. The majority of damage (57 % of cases) was recorded in winter (December-March). Snow depth and temperature did not influence the frequency of damage. The incidences of damage increased with decreasing distance from the woodland patches, therefore, 69 % of cases in Białowieża Forest, and 80 % in Knyszyn Forest were recorded closer than 0.5 km from nearest woodland patch. The majority of the crops damaged by bison were cereals (61 %) but also hay (20 %) and rape (13 %). When compared to the availability of crops, bison strongly selected rape and rye in both regions. This study is the first addressing the increasing problem of human-bison conflict in re-introduced populations and analyzing long-term data on crop depredation. Such situations probably occur in the majority of growing and expanding bison populations, however, it has not yet to be monitored and is rather neglected in post-Soviet countries.

2016-10-01

The purpose of the present study was to examine mock juror perceptions of rape victims based on the sex of the offender and victim (male offender/female victim vs. female offender/male victim), relationship to the offender (stranger vs. acquaintance vs. intimate partner), revictimization (no revictimization vs. revictimization), and individual differences in rape myth acceptance (RMA) and life history strategy (LHS). Participants (N = 332) read a vignette describing a forcible rape scenario and completed victim and perpetrator blame scales, the Mini-K, and a gender-neutral Rape Myth Acceptance Scale. Results indicated increased victim blame in revictimization conditions, as well as female offender/male victim conditions. A significant mediation effect of LHS on victim blame through the indirect effect of RMA was found, which is predicted from life history theory. Implications of these findings are discussed. © The Author(s) 2015.

To determine the prevalence and pattern of rape in Enugu, southeast Nigeria. A prospective descriptive study was conducted among female survivors of rape who presented at the emergency gynecologic and/or forensic unit of Enugu State University Teaching Hospital between February 2012 and July 2013. Data were collected via a pretested interviewer-administered questionnaire. Among 1374 gynecologic emergencies, there were 121 (8.8%) rape cases. The mean age of the rape survivors was 13.1±8.1 years. Ninety (74.4%) survivors were younger than 18 years. At least 72 hours had passed since the rape for 74 (61.2%) cases. The perpetrator was known to 74 (82.2%) patients younger than 18 years and 18 (58.1%) aged at least 18 years (P=0.013). The location of the rape was the bush or an uncompleted building for 36 (29.8%) and the perpetrator's residence for another 36 (29.8%). Four (3.3%) individuals became pregnant after the rape. A considerable proportion of patients with gynecologic emergencies had been raped. Individuals should be encouraged to report to the hospital quickly to prevent unwanted pregnancy and sexually transmitted infections.

The impact of sexual enhancement alcohol expectancies and risky behavior on alcohol-involved rape among college women.

PubMed

Messman-Moore, Terri L; Ward, Rose Marie; DeNardi, Kathleen A

2013-04-01

A structural equation model examined sexual enhancement alcohol expectancies, heavy episodic drinking (HED), and risky sexual behavior as correlates of alcohol-involved rape in a sample of 353 college women. Prevalence of alcohol-involved rape was 15.6%. Sexual enhancement alcohol expectancies were indirectly associated with alcohol-involved rape via increased levels of HED, greater likelihood of sex while intoxicated, and number of sex partners. All forms of risky behavior were associated with alcohol-involved rape although HED had the strongest relationship. Findings suggest continued focus on women's positive alcohol expectancies and HED as risk factors for alcohol-involved rape. Implications for intervention will be discussed.

Landscape-scale distribution and persistence of genetically modified oilseed rape (Brassica napus) in Manitoba, Canada.

Knispel, Alexis L; McLachlan, Stéphane M

2010-01-01

Genetically modified herbicide-tolerant (GMHT) oilseed rape (OSR; Brassica napus L.) was approved for commercial cultivation in Canada in 1995 and currently represents over 95% of the OSR grown in western Canada. After a decade of widespread cultivation, GMHT volunteers represent an increasing management problem in cultivated fields and are ubiquitous in adjacent ruderal habitats, where they contribute to the spread of transgenes. However, few studies have considered escaped GMHT OSR populations in North America, and even fewer have been conducted at large spatial scales (i.e. landscape scales). In particular, the contribution of landscape structure and large-scale anthropogenic dispersal processes to the persistence and spread of escaped GMHT OSR remains poorly understood. We conducted a multi-year survey of the landscape-scale distribution of escaped OSR plants adjacent to roads and cultivated fields. Our objective was to examine the long-term dynamics of escaped OSR at large spatial scales and to assess the relative importance of landscape and localised factors to the persistence and spread of these plants outside of cultivation. From 2005 to 2007, we surveyed escaped OSR plants along roadsides and field edges at 12 locations in three agricultural landscapes in southern Manitoba where GMHT OSR is widely grown. Data were analysed to examine temporal changes at large spatial scales and to determine factors affecting the distribution of escaped OSR plants in roadside and field edge habitats within agricultural landscapes. Additionally, we assessed the potential for seed dispersal between escaped populations by comparing the relative spatial distribution of roadside and field edge OSR. Densities of escaped OSR fluctuated over space and time in both roadside and field edge habitats, though the proportion of GMHT plants was high (93-100%). Escaped OSR was positively affected by agricultural landscape (indicative of cropping intensity) and by the presence of an

Rape is considered a stressful trauma and often with durable consequences. How the aftermath of rape is for young adolescents' girls considering acute stress is an overlooked field and remains to be studied. In this study, we wanted to investigate acute stress among adolescent victims of rape and the psychometric properties of the Acute Stress Checklist for Children (ASC-Kids). A clinical sample (n = 79) of raped girls, 13-17 years old who had turned to a special rape victim unit for treatment, answered the ASC-Kids. ASC-Kids was also given to a group of minor stressed, non-raped adolescents in the same age range (n = 154) together with the University of California at Los Angeles Post-traumatic Stress Disorder Reaction Index (UCLA PTSD RI), and the Sense of Coherence Scale 13 (SOC-13). The scores from the groups were compared and showed significant differences in mean values on all the diagnostic criteria of acute stress disorder. In the clinical group, 36.7% obtained full ASD criteria. ASC-Kids could discriminate well between groups. Cronbach's alpha was found to be excellent, and the correlation between the UCLA PTSD RI and ASC-Kids found to be good; both ASC-Kids and UCLA PTSD RI had a good and moderate negative correlation with SOC-13. Adolescent female rape victims were shown to have a very high level of acute stress, and the ASC-Kids was found to have sound psychometrics and can be a valuable screening instrument to support clinicians in their assessments of an indication of adolescents after potentially stressful events such as rape.

2001-02-01

This prospective study examines the epidemiology of physical attack and rape among a sample of 171 not-in-treatment, crack-cocaine using women. Since initiating crack use, 62% of the women reported suffering a physical attack. The annual rate of victimization by physical attack was 45%. Overall, more than half of the victims sought medical care subsequent to an attack. The prevalence of rape since crack use was initiated was 32%, and the annual rate was 11%. Among those women having been raped since they initiated crack use, 83% reported they were high on crack when the crime occurred as were an estimated 57% of the perpetrators. Logistic regression analyses showed that duration of crack use, arrest for prostitution, and some college education were predictors of having experienced a physical attack. Duration of crack use and a history of prostitution were predictors of suffering a rape. Drug abuse treatment programs must be sensitive to high levels of violence victimization experienced by crack-cocaine using women. Screening women for victimization, and treating the problems that emanate from it, may help make drug abuse treatment more effective.

Optimization of Nitrogen Rate and Planting Density for Improving Yield, Nitrogen Use Efficiency, and Lodging Resistance in Oilseed Rape

Yield and lodging related traits are essential for improving rapeseed production. The objective of the present study was to investigate the influence of plant density (D) and nitrogen (N) rates on morphological and physiological traits related to yield and lodging in rapeseed. We evaluated Huayouza 9 for two consecutive growing seasons (2014–2016) under three plant densities (LD, 10 plants m−2; MD, 30 plants m−2; HD, 60 plants m−2) and four N rates (0, 60, 120, and 180 kg ha−1). Experiment was laid out in split plot design using density as a main factor and N as sub-plot factor with three replications each. Seed yield was increased by increasing density and N rate, reaching a peak at HD with 180 kg N ha−1. The effect of N rate was consistently positive in increasing the plant height, pod area index, 1,000 seed weight, shoot and root dry weights, and root neck diameter, reaching a peak at 180 kg N ha−1. Plant height was decreased by increasing D, whereas the maximum radiation interception (~80%) and net photosynthetic rate were recorded at MD at highest N. Lodging resistance and nitrogen use efficiency significantly increased with increasing D from 10 to 30 plants m−2, and N rate up to 120 kg ha−1, further increase of D and N decreased lodging resistance and NUE. Hence, our study implies that planting density 30 plants m−2 can improve yield, nitrogen use efficiency, and enhance lodging resistance by improving crop canopy. PMID:28536581

Scripts are influential in shaping sexual behaviors. Prior studies have examined the influence of individuals' rape scripts. However, these scripts have not been evaluated among diverse groups. The current study examined the rape scripts of African American (n = 72) and European American (n = 99) college women. Results supported three rape scripts: the "real rape," the "party rape," and the mismatched intentions rape, that were equally common. However, there were some differences, with African Americans' narratives more often including active victim resistance and less often containing victim vulnerability themes. Societal and cultural influences on rape scripts are discussed. © The Author(s) 2016.

Rape is an established risk factor for mental health disorders, such as posttraumatic stress disorder (PTSD), major depressive episodes (MDE), and substance use disorders. The majority of studies have not differentiated substance-involved rape or examined comorbid diagnoses among victims. Therefore, the aim of the present study was to estimate the prevalence of common trauma-related psychiatric disorders (and their comorbidity) in a national sample of women, with an emphasis on distinguishing between rape tactics. A secondary objective was to estimate the risk for psychiatric disorders among victims of variant rape tactics, in comparison to non-victims. A nationally representative population-based sample of 3,001 non-institutionalized, civilian, English or Spanish speaking women (aged 18-86 years) participated in a structured telephone interview assessing rape history and DSM-IV criteria for PTSD, MDE, alcohol abuse (AA), and drug abuse (DA). Descriptive statistics and multivariate logistic regression analyses were employed. Women with rape histories involving both substance facilitation and forcible tactics reported the highest current prevalence of PTSD (36%), MDE (36%), and AA (20%). Multivariate models demonstrated that this victim group was also at highest risk for psychiatric disorders, after controlling for demographics and childhood and multiple victimization history. Women with substance-facilitated rapes reported higher prevalence of substance abuse in comparison to women with forcible rape histories. Comorbidity between PTSD and other psychiatric disorders was higher among rape victims in comparison to non-rape victims. Researchers and clinicians should assess substance-facilitated rape tactics and attend to comorbidity among rape victims. Empirically supported treatments are needed to address the complex presentations observed among women with variant rape histories.

Impunity or immunity: wartime male rape and sexual torture as a crime against humanity.

PubMed

Zawati, Hilmi M

2007-01-01

This paper seeks to analyze the phenomenon of wartime rape and sexual torture of Croatian and Iraqi men and to explore the avenues for its prosecution under international humanitarian and human rights law. Male rape, in time of war, is predominantly an assertion of power and aggression rather than an attempt on the part of the perpetrator to satisfy sexual desire. The effect of such a horrible attack is to damage the victim's psyche, rob him of his pride, and intimidate him. In Bosnia- Herzegovina, Croatia, and Iraq, therefore, male rape and sexual torture has been used as a weapon of war with dire consequences for the victim's mental, physical, and sexual health. Testimonies collected at the Medical Centre for Human Rights in Zagreb and reports received from Iraq make it clear that prisoners in these conflicts have been exposed to sexual humiliation, as well as to systematic and systemic sexual torture. This paper calls upon the international community to combat the culture of impunity in both dictator-ruled and democratic countries by bringing the crime of wartime rape into the international arena, and by removing all barriers to justice facing the victims. Moreover, it emphasizes the fact that wartime rape is the ultimate humiliation that can be inflicted on a human being, and it must be regarded as one of the most grievous crimes against humanity. The international community has to consider wartime rape a crime of war and a threat to peace and security. It is in this respect that civilian community associations can fulfill their duties by encouraging victims of male rape to break their silence and address their socio-medical needs, including reparations and rehabilitation.

We described the use of antiretroviral drugs to prevent HIV transmission among children and adolescents victims of rape in Abidjan (Ivory Coast). We conducted a retrospective and descriptive study on children (0-9 years) and adolescents (10-19 years) victims of rape between 2000 and 2013. We analyzed the patients' socio-demographic characteristics and the modality of the chemoprophylaxis. We included 10 children and 89 adolescents in the study. The median age was 16 years old (3-19 years). The median time to consultation was 23.5 hours (5-152 hours). The antiretroviral chemoprophylaxis was administered to 92 patients (93%). No HIV and HBV seroconversion was observed after a 3-month follow-up. A better management of rape victims is required in Abidjan. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Effects of Reduced Terrestrial LiDAR Point Density on High-Resolution Grain Crop Surface Models in Precision Agriculture

Hämmerle, Martin; Höfle, Bernhard

2014-01-01

3D geodata play an increasingly important role in precision agriculture, e.g., for modeling in-field variations of grain crop features such as height or biomass. A common data capturing method is LiDAR, which often requires expensive equipment and produces large datasets. This study contributes to the improvement of 3D geodata capturing efficiency by assessing the effect of reduced scanning resolution on crop surface models (CSMs). The analysis is based on high-end LiDAR point clouds of grain crop fields of different varieties (rye and wheat) and nitrogen fertilization stages (100%, 50%, 10%). Lower scanning resolutions are simulated by keeping every n-th laser beam with increasing step widths n. For each iteration step, high-resolution CSMs (0.01 m2 cells) are derived and assessed regarding their coverage relative to a seamless CSM derived from the original point cloud, standard deviation of elevation and mean elevation. Reducing the resolution to, e.g., 25% still leads to a coverage of >90% and a mean CSM elevation of >96% of measured crop height. CSM types (maximum elevation or 90th-percentile elevation) react differently to reduced scanning resolutions in different crops (variety, density). The results can help to assess the trade-off between CSM quality and minimum requirements regarding equipment and capturing set-up. PMID:25521383

Camelina [Camelina sativa (L.) Crantz.] is an industrial oilseed crop in the Brassicaceae family with multiple uses. Currently, camelina is not used as a cover crop, but it has the potential to be used as such in maize-soybean-wheat cropping systems. The objectives of this study were to determine the agronomic performance and nutrient scavenging potential of winter camelina in comparison with other common cover crops. Experiments were conducted in Fargo, ND in 2015 and 2016, and in Prosper, ND in 2015. The experimental design was a randomized complete block design with a split-plot arrangement with three replicates. The main plot was the sowing date and the subplot were camelina cultivars as well as other common cover crops in the area. Sowing dates were targeted to 15 August and September 1, although the final dates varied slightly each year. Biomass yield, N content of the biomass N uptake and P uptake was evaluated. Winter camelina N and P uptake ranged between 21 and 30.5 kg N ha-1 and 3.4 to 5.3 kg P ha-1. The nutrient scavenging potential of winter camelina was similar to other cover crops although slightly lower than turnip (Brassica rapa L.), radish (Raphanus sativus L.), and rape (Brassica napus L.) cultivars which had significantly higher P uptake than winter camelina and the other cover crops in the study. An evaluation of spring regrowth and cover indicated that only rye, winter camelina, and pennycress (Thlaspi arvense L.) survived the winter, although a few plants of triticale (x Trticosecale Witt.) and rape were found on a few plots. Because of the high variability on the plots there were no significant differences among the surviving cover crops on soil coverage. The soil coverage for rye cultivars was 25 and 35% and for camelina cv. Bison was 27%.In 2016, biomass yield was not significant for sowing date, cultivars, or their interaction. Winter camelina cultivars biomass yield fluctuated between 1.15 and 2.33 Mg dry matter ha-1 on the first sowing

Studies of rape of women seldom distinguish between men's participation in acts of single and multiple perpetrator rape. Multiple perpetrator rape (MPR) occurs globally with serious consequences for women. In South Africa it is a cultural practice with defined circumstances in which it commonly occurs. Prevention requires an understanding of whether it is a context specific intensification of single perpetrator rape, or a distinctly different practice of different men. This paper aims to address this question. We conducted a cross-sectional household study with a multi-stage, randomly selected sample of 1686 men aged 18-49 who completed a questionnaire administered using an Audio-enhanced Personal Digital Assistant. We attempted to fit an ordered logistic regression model for factors associated with rape perpetration. 27.6 % of men had raped and 8.8 % had perpetrated multiple perpetrator rape (MPR). Thus 31.9 % of men who had ever raped had done so with other perpetrators. An ordered regression model was fitted, showing that the same associated factors, albeit at higher prevalence, are associated with SPR and MPR. Multiple perpetrator rape appears as an intensified form of single perpetrator rape, rather than a different form of rape. Prevention approaches need to be mainstreamed among young men.

The high prevalence of rape and sexual trauma symptomatology among women involved in street-based sex trades is well-established. Because prior research has lacked appropriate, non-sex trade involved comparison groups, it is unknown whether differences exist among similarly situated women who do and do not trade sex. This article explores experiences of childhood and adult rape and symptomatology of sexual abuse trauma among a community-based sample of 322 women who use methamphetamine in San Francisco, California, 61% of whom were involved in the sex trade. Study participants were recruited via respondent-driven sampling and eligible if they were cisgender women, aged 18 or older, current methamphetamine users, and sexually active with at least one cisgender man in the past 6 months. The dependent variable was sexual abuse trauma symptomatology, as measured by the Sexual Abuse Trauma Index (SATI) subscale of the Trauma Symptom Checklist-40 (TSC-40), and the explanatory variable was sex trade involvement. Potential covariates were age, current homelessness, methamphetamine dependence, and experiences of childhood and adult rape. Sixty-one percent of participants had a SATI subscale score suggestive of sexual abuse trauma. The overall prevalence of rape in childhood and adulthood was 52% and 73%, respectively. In bivariate analysis, sex trade involvement and all of the potential covariates except for homelessness and age were associated with a SATI score suggestive of sexual abuse trauma. In multivariate models controlling for significant covariates, there was no longer a statistically significant association between sex trade involvement or childhood rape and an elevated SATI score. Elevated levels of psychological dependence on methamphetamine and experiences of rape as an adult were still associated with a high SATI score. These findings highlight that urban poor women, regardless of sex trade involvement, suffer high levels of rape and related trauma

Rape of women and children is recognized as a health and human rights issue in Tanzania and internationally. Exploration of the prevailing perceptions in rural areas is needed in order to expand the understanding of sexual violence in the diversity of Tanzania's contexts. The aim of this study therefore was to explore and understand perceptions of rape of women and children at the community level in a rural district in Tanzania with the added objective of exploring those perceptions that may contribute to perpetuating and/or hindering the disclosure of rape incidences. A qualitative design was employed using focus group discussions with male and female community members including religious leaders, professionals, and other community members. The discussions centered on causes of rape, survivors of rape, help-seeking and reporting, and gathered suggestions on measures for improvement. Six focus group discussions (four of single gender and two of mixed gender) were conducted. The focus group discussions were recorded, transcribed verbatim, and analyzed using manifest qualitative content analysis. The participants perceived rape of women and children to be a frequent and hidden phenomenon. A number of factors were singled out as contributing to rape, such as erosion of social norms, globalization, poverty, vulnerability of children, alcohol/drug abuse and poor parental care. Participants perceived the need for educating the community to raise their knowledge of sexual violence and its consequences, and their roles as preventive agents. In this rural context, social norms reinforce sexual violence against women and children, and hinder them from seeking help from support services. Addressing the identified challenges may promote help-seeking behavior and improve care of survivors of sexual violence, while changes in social and cultural norms are needed for the prevention of sexual violence.

Child sexual abuse (CSA) is a major global health challenge. Extant literature in Kenya indicates an alarming rate of sexually abused minors presenting to poorly equipped health facilities with untrained health providers for post rape care. National guidelines on management of sexual violence have been in existence since 2004; however, little is known on the impact of these guidelines on post rape care provision to minors. Therefore, the study aims to assess the knowledge, attitudes, and practices of health providers with regard to post rape care provision in a Kenyan District health facility. The study used a triangulation of different qualitative methods: review of 42 health records of minors seeking post rape care, 15 in-depth interviews, and informal conversations with health providers. Findings indicate that the Kenyan national guidelines on management of sexual violence were nonexistent in the health facility. Consequently, health providers possessed limited knowledge on post rape care administration. The limited knowledge translated to poor collection and preservation of evidence, inadequate psychosocial support, and clinical care. In addition, rape myth attitudes and religious beliefs contributed to survivor blaming and provider hesitance in provision of legal abortion care, respectively. To facilitate provision of quality post rape care, policy makers and health institutions' managers need to avail protocols in line with evidence-based best practices to guide health providers in post rape care administration. In addition, there is need for rigorous training and supervision of health professionals to ensure better service provision.

As a result of our investigations we have determined the optimal concentrations of ferrum, cobalt and cuprum nano-powders recommended to be used as micro-fertilizers increasing the yield and feed value of crops at the expense of accumulating biologically active combinations by 25-35%. In unfavorable climate conditions, for example in a case of excess moisture or heat and drought, the plants development and ripening suffer. Our investigations have shown that the stimulating effect of nano-powders has lowered the effect of stress situations on plants development and simultaneously increased the rape seeds yield and quality. Treating the seeds with the drugs being studied has provided the high crop protection. If consider that the maximum efficiency of protectants Chinuk, SK (20 kg/t of seeds) and Cruiser, KS (10 kg/t of seeds) then for the same effect one needs nano-powders 0.1 g per hectare norm of seeds planting.

Oilseed rape is one of the important oil plants. Pod shattering is one of the problems in oilseed rape production especially in regions with dry conditions. One of the important genes in Brassica pod opening is SHATTERPROOF1 (SHP1). Down-regulation of BnSHP1 expression by RNAi can increase resistance to pod shattering. A 470 bp of the BnSHP1 cDNA sequence constructed in an RNAi-silencing vector was transferred to oilseed rape cv. SLM046. Molecular analysis of T2 transgenic plants by RT-PCR and Real-time PCR showed that expression of the BnSHP alleles was highly decreased in comparison with control plants. Morphologically, transgenic plants were normal and produced seeds at greenhouse conditions. At ripening, stage pods failed to shatter, and a finger pressure was needed for pod opening.

Sexual assault and rape perpetration by college men: the role of the big five personality traits.

2010-03-01

A sample of 521 college men completed the Revised NEO Personality Inventory and an expanded version of the Sexual Experiences Survey to examine whether variation in the Big Five personality traits in a normal, college population provides any insight into the nature of sexual assault and rape perpetrators. Rape perpetrators reported lower levels of Agreeableness and Conscientiousness when compared to both sexual assault perpetrators and nonperpetrators, and lower levels of Extraversion when compared to nonperpetrators. Rape perpetrators also endorsed lower levels of tendermindedness, excitement-seeking, warmth, positive emotions, feelings, altruism, competence, and dutifulness, and higher levels of vulnerability. Contrary to expectation, overall personality profiles followed remarkably comparable patterns for sexual assault and nonperpetrators, suggesting that sexual assault perpetrators were more similar to nonperpetrators than to rape perpetrators. Findings suggest that individuals who perpetrate sexual offenses, particularly rape, differ from nonperpetrators on dimensions of normal personality. Clinical and research implications are discussed.

In agricultural fields, soil and water quality preservation is strongly influenced by pesticides use and behavior. To limit the environmental impacts of agricultural activities, best management practices such as the use of cover crops are encouraged. Cover crops during the fallow period were found to be efficient in reducing nitrate leaching, controlling soil erosion, improving soil organic content and enhancing soil biological activity. This technique was also found to modify soil water dynamics in the following crop. According to these effects, modifications on pesticide behavior in soil, such as sorption, degradation and transport, are expected (Alletto et al., 2012 ; 2013). In this study, the impact of the nature and level of decomposition of cover crop was studied on the sorption characteristics of three pesticides. These pesticides differed in their physicochemical characteristics (hydrophobicity, solubility, persistence) and were two herbicides, S-metolachlor and glyphosate, which are largely used in maize production and predominantly found as pollutants in water; and one fungicide, epoxiconazole. Correlations between pesticide sorption and physicochemical characteristics of the cover crop residues were studied. Residues of oat, turnip rape, red clover and phacelia were collected in March 2011 and incubated at 28°C and at the water holding capacity during 0, 6, 28 or 56 days. For each date, adsorption of the three radiolabeled pesticides was measured in batch on the different cover crop residues, and their biochemical composition (Van Soest fractionation), hydrophobicity (contact angle measurement) and C/N ratio were determined. Results showed that the adsorption of the pesticides differed significantly according to (i) the pesticide, (ii) the nature of cover crop, (iii) the decomposition level of the cover crop and the interaction cover crop x decomposition time. Epoxiconazole was the most adsorbed molecule, with Kd values ranging from 161 ± 30 L/Kg (oat

With dwindling available agricultural land, concurrent with increased demand for oil, there is much current interest in raising oil crop productivity. We have been addressing this issue by studying the regulation of oil accumulation in oilseed rape (Brassica napus L). As part of this research we have carried out a detailed lipidomic analysis of developing seeds. The molecular species distribution in individual lipid classes revealed quite distinct patterns and showed where metabolic connections were important. As the seeds developed, the molecular species distributions changed, especially in the period of early (20days after flowering, DAF) to mid phase (27DAF) of oil accumulation. The patterns of molecular species of diacylglycerol, phosphatidylcholine and acyl-CoAs were used to predict the possible relative contributions of diacylglycerol acyltransferase (DGAT) and phospholipid:diacylglycerol acyltransferase to triacylglycerol production. Our calculations suggest that DGAT may hold a more important role in influencing the molecular composition of TAG. Enzyme selectivity had an important influence on the final molecular species patterns. Our data contribute significantly to our understanding of lipid accumulation in the world's third most important oil crop. Copyright © 2018 The Authors. Published by Elsevier B.V.

This study examined the antecedents for the acceptance of rape myths. The information motivation behavioral skills model was the basis for this study. In this cross-sectional study at a northeastern university, 237 students consented to participate in an online survey examining knowledge, social norms regarding sexual behavior, future time perspective, and rape myth acceptance (RMA). The majority of the sample was female. Forty-one percent believed that a woman who was raped while drunk was responsible. Men had higher RMA and the less sexual knowledge they had, the more they accepted the rape myths. Direction is provided regarding primary prevention of sexual assault.

High-density row crop production occurs in three areas of Alabama that are underlain by productive aquifers, northern Alabama, southeastern Alabama, and Baldwin County in southwestern Alabama. The U.S. Geological Survey collected five groundwater samples from each of these three areas during 2009 for analysis of selected pesticides. Results of these analyses showed detections for 37 of 152 analytes. The three most frequently detected compounds were atrazine, 2-Chloro-4-isopropylamino-6-amino-triazine (CIAT), and metolachlor. The highest concentration for any analyte was 4.08 micrograms per liter for metolachlor.

Overexpression of BnaWGR1 causes ROS accumulation and promotes leaf senescence. BnaWGR1 binds to promoters of RbohD and RbohF and regulates their expression. Manipulation of leaf senescence process affects agricultural traits of crop plants, including biomass, seed yield and stress resistance. Since delayed leaf senescence usually enhances tolerance to multiple stresses, we analyzed the function of specific MAPK-WRKY cascades in abiotic and biotic stress tolerance as well as leaf senescence in oilseed rape (Brassica napus L.), one of the important oil crops. In the present study, we showed that expression of one WRKY gene from oilseed rape, BnaWGR1, induced an accumulation of reactive oxygen species (ROS), cell death and precocious leaf senescence both in Nicotiana benthamiana and transgenic Arabidopsis (Arabidopsis thaliana). BnaWGR1 regulates the transcription of two genes encoding key enzymes implicated in production of ROS, that is, respiratory burst oxidase homolog (Rboh) D and RbohF. A dual-luciferase reporter assay confirmed the transcriptional regulation of RbohD and RbohF by BnaWGR1. In vitro electrophoresis mobility shift assay (EMSA) showed that BnaWGR1 could bind to W-box cis-elements within promoters of RbohD and RbohF. Moreover, RbohD and RbohF were significantly upregulated in transgenic Arabidopsis overexpressing BnaWGR1. In summary, these results suggest that BnaWGR1 could positively regulate leaf senescence through regulating the expression of RbohD and RbohF genes.

Sexual abuse prevention with high-risk males: the roles of victim empathy and rape myths.

PubMed

Schewe, P A; O'Donohue, W

1993-01-01

The outcome of two sexual abuse prevention programs, one emphasizing victim empathy and the other stressing modifying rape myths, was evaluated with high-risk males. Sixty-eight high-risk males, as determined by self-reported likelihood of committing sexual abuse, were randomly assigned to an empathy-treatment, a facts-treatment, or a no-treatment control group. Treatment effects were assessed using subjects' pre- and post-treatment scores on the Likelihood of Sexually Abusing scale, the Rape Empathy Scale, the Acceptance of Interpersonal Violence scale, the Adversarial Sexual Beliefs Scale, and a test of self-reported sexual arousal to forced versus consenting sex. In addition, posttest scores on an Asch-type conformity measure were obtained. Results of validity checks indicated that high-risk subjects differed from low-risk subjects on a number of rape-related variables, that the victim-empathy condition increased subjects' empathy, and that subjects found both treatments to be credible and helpful. Comparisons between the empathy-, facts-, and no-treatment group contraindicated the practice of dispelling rape myths as a method of preventing rape among high-risk males.

Rape myth attitudes (RMAs) can excuse men for rape, placing blame on female victims. This study identified and classified RMAs in rural western Kenya through 31 focus group discussions with youths and adults. We found that about half of the participants were likely to blame victims unconditionally. Stereotypes about rape victims and perpetrators were rife. Five of seven standardly used RMA categories emerged spontaneously in focus groups, along with a new category: "she owed him." Based on the data, we developed a "blame index" to assess the likelihood of community victim blaming in Kenya. To reduce victim blaming and bring about more prosecutions for rape, community education, teacher training, and reforms of rape laws are highly recommended.

Older adults who have experienced traumatic events earlier in life may be especially vulnerable to additional challenges associated with aging. In a cross-sectional study of older females, the present study examines whether a history of rape is associated with current psychological and health problems. This study used existing data from the female respondents (N = 1228) in the National Social Life, Health, and Aging Project (NSHAP), a national probability sample of adults between the ages of 57 and 85 interviewed in their homes. It was determined whether or not the participant experienced forced sexual contact since the age of 18. Measures of psychological health (e.g., scales of depression, anxiety, and loneliness), the presence or absence of a number of serious health problems, and a one-item measure of self-esteem were obtained. Adult rape occurred in 7% of the sample. On average, 36 years had elapsed since the rape had occurred. Using structural equation modeling (SEM), rape was associated with lower self-esteem, psychological, and physical health functioning. Self-esteem partially mediated the association between rape and psychological functioning, but not health functioning. These associations were significant even after controlling for participant characteristics and risky health behaviors. Mechanisms linking prior rape to psychological and health problems in older age are discussed, as well as treatment recommendations for symptomatic older adults.

The health, mental health, and well-being benefits of rape crisis counseling.

There is very little research on interventions to alleviate the distress experienced following rape. This action research project developed and piloted the "Taking Back Control" tool that measured the impact of rape crisis counseling over time. Five rape crisis centers in the North of England agreed to pilot the tool, which was administered by the client's counselor, either on Week 1 or 2, and then repeated every 6 weeks until the end of counseling. Eighty-seven clients completed at least two questionnaires. This allowed us to measure change from their first compared with their last data collection point. The most change was made in relation to the statement "I feel empowered and in control of my life," where 61% strongly/disagreed at the first data collection point compared with 31% at the last data collection point. Large shifts were also seen in relation to "I have 'flashbacks' about what happened" and "I have panic attacks." Overall, some degree of positive change was seen for all measures. This research, despite some limitations, begins to develop an evidence base for rape crisis centers to demonstrate their benefits and to assess and develop their own practice.

A randomized between-group design was used to evaluate efficacy of a video intervention to reduce PTSD and other mental health problems, implemented prior to the forensic medical exam conducted within 72 hours post-sexual assault. Participants were 140 female victims of sexual assault (68 video/72 nonvideo) ages 15 or older. Assessments were targeted for 6 weeks (Time 1) and 6 months (Time 2) post-assault. At Time 1, the intervention was associated with lower scores on measures of PTSD and depression among women with prior rape history relative to scores among women with prior rape history in the standard care condition. At Time 2, depression scores were also lower among those with a prior history who were in the video relative to standard care condition. Small effects indicating higher PTSD and BAI scores among women without a prior history in the video condition were observed at Time 1. Accelerated longitudinal growth curve analysis indicated a video x prior rape history interaction for PTSD, yielding four patterns of symptom trajectory over time. Women with a prior rape history in the video condition generally maintained the lowest level of symptoms. PMID:17585872

Sexual assault nurse examiners' perceptions of their relationship with doctors, rape victim advocates, police, and prosecutors.

PubMed

Maier, Shana L

2012-05-01

In response to the negative and inefficient treatment of rape victims by emergency room personnel, the first Sexual Assault Nurse Examiner (SANE) programs began in the late 1970s. While SANEs, doctors, rape victim advocates, police officers and prosecutors work together to ensure the most comprehensive and sensitive care of rape victims, they all have very different roles and objectives. This research explores SANEs' perceptions of their relationships with other professionals who treat or interact with rape victims. Data from interviews with 39 Sexual Assault Nurse Examiners from four East Coast states indicate positive relationships are marked by open communication, respect shown towards SANEs as well as rape victims, and a sense of appreciation among SANEs. On the contrary, negative relationships result when SANEs believe police treat victims poorly, when advocates overstep boundaries and question SANEs about evidence collection or the exam, and when prosecutors fail to properly prepare them to testify during a trial.

An important adaptation of plants to phosphorus (P) deficiency is to alter root system architecture (RSA) to increase P acquisition from the soil, but soil-based observations of RSA are technically challenging, especially in mature plants. The aim of this study was to investigate the root development and RSA of oilseed rape (Brassica napus L.) under low and high soil P conditions during an entire growth cycle. A new large Brassica-rhizotron system (approx. 118-litre volume) was developed to study the RSA dynamics of B. napus 'Zhongshuang11' in soils, using top-soils supplemented with low P (LP) or high P (HP) for a full plant growth period. Total root length (TRL), root tip number (RTN), root length density (RLD), biomass and seed yield traits were measured. TRL and RTN increased more rapidly in HP than LP plants from seedling to flowering stages. Both traits declined from flowering to silique stages, and then increased slightly in HP plants; in contrast, root senescence was observed in LP plants. RSA parameters measured from the polycarbonate plates were empirically consistent with analyses of excavated roots. Seed yield and shoot dry weights were closely associated positively with root dry weights, TRL, RLD and RTN at both HP and LP. The Brassica-rhizotron system is an effective method for soil-based root phenotyping across an entire growth cycle. Given that root senescence is likely to occur earlier under low P conditions, crop P deficiency is likely to affect late water and nitrogen uptake, which is critical for efficient resource use and optimal crop yields. © The Author 2016.

Barn, Ravinder; Powers, Ráchael A

2018-05-01

Much of the literature on rape, victim blaming, and rape myth acceptance is focused on the United States, and there is a general dearth of such scholarly activity in other countries. This article offers insights on university students' perspectives in two new country contexts-India and the United Kingdom. A total of 693 students contributed to the data collection for this study. Rape myth acceptance was fairly low for both countries, however, students in India were more likely to endorse rape myths. Several demographic characteristics were significant for rape myth acceptance in each country. This study makes an important contribution to the extant literature to address paucity of knowledge and promote understandings to help develop country-specific and appropriate policy, practice, and education and awareness programs. In particular, the study provides novel comparative findings on rape myth acceptance in new country contexts to help advance academic thinking in this area of work.

Self-defense or undermining the self? Exploring the possibilities and limitations of a novel anti-rape technology.

White, Deborah; Rees, Gethin

2014-03-01

Despite decades of feminist-inspired law reforms, rape remains highly prevalent. While many continue to fight for broad cultural and institutional changes, some argue that more immediate interventions are required. Self-defense techniques represent a key strategy of resistance to rape, and empirical evidence suggests that women's active resistance may hold a number of positive benefits. In this essay, we compare the aims and objectives of a novel anti-rape technology, known as the Rape-aXe, with traditional self-defense techniques, focusing upon the potential for both to resist individual acts of sexual aggression and, more broadly, end gendered sexual violence.

Despite the important focus on the notion of cognitive distortions in the sexual offending area, the relevance of underlying cognitive schemas in sexual offenders has also been suggested. The aim of the present study was to investigate a potential relationship between Early Maladaptive Schemas (EMSs) and cognitive distortions in rapists. A total of 33 men convicted for rape completed the Bumby Rape Scale (BRS), the Young Schema Questionnaire - Short form-3 (YSQ-S3), the Brief Symptom Inventory (BSI), and the Socially Desirable Response Set Measure (SDRS-5). Results showed a significant relationship between the impaired limits schematic domain and the Justifying Rape dimension of the BRS. Specifically, after controlling for psychological distress levels and social desirability tendency, the entitlement/grandiosity schema from the impaired limits domain was a significant predictor of cognitive distortions related to Justifying Rape themes. Overall, despite preliminary, there is some evidence that the Young's Schema-Focused model namely the impaired limits dimension may contribute for the conceptualization of cognitive distortions in rapists and further investigation is recommended.

2014-01-01

Our study explores the role of victims' consultation with others about whether or not to report their rape to police. Three groups were observed within this sample of 435 rape victims from a national telephone household probability sample of women: those who did not consult with anyone about reporting (n = 364), those who consulted with someone and were encouraged to report to police (n = 40), and those who consulted with someone and were not encouraged to report (n = 31). Descriptive analyses indicated that the encouraged group was more likely to report to police than either of the other two groups (which did not differ from each other). Because there were no differences between the two consulting groups on demographic or rape-related variables, they were combined in subsequent analyses. Consulting with others about whether to report, peri-traumatic fear of injury or death, assault perpetration by a stranger, and concerns about contracting a sexually transmitted disease were significant predictors of reporting to police after controlling for other significant predictors in a multivariate regression analysis. Implications of these findings are discussed, including the benefits and consequences of formal rape reporting for victims, and the role that disclosure recipients may have in assisting victims post-rape (e.g., encouragement of reporting, emotional support).

The main aim of the present study was to specify and test a structural model to examine the relationships between four psychopathy dimensions (Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Antisocial Behavior), childhood exposure to violence, and rape myth acceptance while controlling for gender, age, sample type (prisoner vs. non-prisoner), and relationship status. Participants were a sample of non-offending adults (n = 319) recruited from the University of Security in Poznan, and a sample of prisoners (n = 129) incarcerated in Stargard Szczecinski Prison. Results indicated that the model provided a good fit for the data, and that Callous Affect and childhood exposure to violence had a significant positive effect on attitudes toward rape and rape victims.

Simulating crop growth with Expert-N-GECROS under different site conditions in Southwest Germany

2016-04-01

When feedbacks between the land surface and the atmosphere are investigated by Atmosphere-Land surface-Crop-Models (ALCM) it is fundamental to accurately simulate crop growth dynamics as plants directly influence the energy partitioning at the plant-atmosphere interface. To study both the response and the effect of intensive agricultural crop production systems on regional climate change in Southwest Germany, the crop growth model GECROS (YIN & VAN LAAR, 2005) was calibrated based on multi-year field data from typical crop rotations in the Kraichgau and Swabian Alb regions. Additionally, the SOC (soil organic carbon) model DAISY (MÜLLER et al., 1998) was implemented in the Expert-N model tool (ENGEL & PRIESACK, 1993) and combined with GECROS. The model was calibrated based on a set of plant (BBCH, LAI, plant height, aboveground biomass, N content of biomass) and weather data for the years 2010 - 2013 and validated with the data of 2014. As GECROS adjusts the root-shoot partitioning in response to external conditions (water, nitrogen, CO2), it is suitable to simulate crop growth dynamics under changing climate conditions and potentially more frequent stress situations. As C and N pools and turnover rates in soil as well as preceding crop effects were expected to considerably influence crop growth, the model was run in a multi-year, dynamic way. Crop residues and soil mineral N (nitrate, ammonium) available for the subsequent crop were accounted for. The model simulates growth dynamics of winter wheat, winter rape, silage maize and summer barley at the Kraichgau and Swabian Alb sites well. The Expert-N-GECROS model is currently parameterized for crops with potentially increasing shares in future crop rotations. First results will be shown.

Pornography and rape: theory and practice? Evidence from crime data in four countries where pornography is easily available.

Kutchinsky, B

1991-01-01

We have looked at the empirical evidence of the well-known feminist dictum: "pornography is the theory--rape is the practice" (Morgan, 1980). While earlier research, notably that generated by the U.S. Commission on Obscenity and Pornography (1970) had found no evidence of a causal link between pornography and rape, a new generation of behavioral scientists have, for more than a decade, made considerable effort to prove such a connection, especially as far as "aggressive pornography" is concerned. The first part of the article examines and discusses the findings of this new research. A number of laboratory experiments have been conducted, much akin to the types of experiments developed by researchers of the effects of nonsexual media violence. As in the latter, a certain degree of increased "aggressiveness" has been found under certain circumstances, but to extrapolate from such laboratory effects to the commission of rape in real life is dubious. Studies of rapists' and nonrapists' immediate sexual reactions to presentations of pornography showed generally greater arousal to non-violent scenes, and no difference can be found in this regard between convicted rapists, nonsexual criminals and noncriminal males. In the second part of the paper an attempt was made to study the necessary precondition for a substantial causal relationship between the availability of pornography, including aggressive pornography, and rape--namely, that obviously increased availability of such material was followed by an increase in cases of reported rape. The development of rape and attempted rape during the period 1964-1984 was studied in four countries: the U.S.A., Denmark, Sweden and West Germany. In all four countries there is clear and undisputed evidence that during this period the availability of various forms of pictorial pornography including violent/dominant varieties (in the form of picture magazines, and films/videos used at home or shown in arcades or cinemas) has developed

The effect of victim information on causality judgments in a rape trial scenario.

D. M. Rempala and F. B. Bernieri (2005) showed that in a date-rape trial scenario, increasing the amount of neutral, nondiagnostic information (i.e., information unrelated to the case) about the rape victim decreases the percentage of guilt verdicts. The authors attempted to determine the causal mechanism for this phenomenon. Participants read 1 of 4 rape trial scenarios (which differed only in the amount of non diagnostic information about the defendant and victim), then provided a verdict and rated the targets on several dimensions. The authors replicated pattern of guilt verdicts in the Rempala and Bernieri study (p < .05), and a path analysis indicated that increased victim information altered causality judgments, which then affected guilt verdicts.

Rape revisited: sexual violence against women in the former Yugoslavia.

PubMed

Valentich, M

1994-01-01

This article presents information on the rape of women in the former Yugoslavia, focusing more on Muslim women in Bosnia-Herzegovina, and examines the evolutionary, sociological, psychological, and feminist theories of this form of sexual violence. Using a case study approach, through documentation from newspapers and other media accounts, this paper investigated the sexual violence that featured strongly in the campaign of ethnic cleansing or genocide of Muslims in Bosnia-Herzegovina. It was noted that the variables of power, sex, and aggression in the context of war seem to be linked. This is particularly evident when authority legitimates sexual aggression. Without the backing of authority, some rape is expected, but not of such proportion or brutality. In terms of the theories, the evolutionary perspective appears to have limited applicability in explaining rape as an act of war. However, the feminist and macrosociological multivariate theories that focus on heterogeneity of the population, a cultural foundation of very traditional gender roles, and a historical tradition that legitimates sexual violence by armies in war-time, provide more persuasive insights.

Can phosphorus application and cover cropping alter arbuscular mycorrhizal fungal communities and soybean performance after a five-year phosphorus-unfertilized crop rotational system?

Understanding diversity of arbuscular mycorrhizal fungi (AMF) is important for optimizing their role for phosphorus (P) nutrition of soybeans ( Glycine max (L.) Merr.) in P-limited soils. However, it is not clear how soybean growth and P nutrition is related to AMF colonization and diversity of AMF communities in a continuous P-unfertilized cover cropping system. Thus, we investigated the impact of P-application and cover cropping on the interaction among AMF colonization, AMF diversity in soybean roots, soybean growth and P nutrition under a five-year P-unfertilized crop rotation. In this study, we established three cover crop systems (wheat, red clover and oilseed rape) or bare fallow in rotation with soybean. The P-application rates before the seeding of soybeans were 52.5 and 157.5 kg ha -1 in 2014 and 2015, respectively. We measured AMF colonization in soybean roots, soybean growth parameters such as aboveground plant biomass, P uptake at the flowering stage and grain yields at the maturity stage in both years. AMF community structure in soybean roots was characterized by specific amplification of small subunit rDNA. The increase in the root colonization at the flowering stage was small as a result of P-application. Cover cropping did not affect the aboveground biomass and P uptake of soybean in both years, but the P-application had positive effects on the soybean performance such as plant P uptake, biomass and grain yield in 2015. AMF communities colonizing soybean roots were also significantly influenced by P-application throughout the two years. Moreover, the diversity of AMF communities in roots was significantly influenced by P-application and cover cropping in both years, and was positively correlated with the soybean biomass, P uptake and grain yield throughout the two years. Our results indicated that P-application rather than cover cropping may be a key factor for improving soybean growth performance with respect to AMF diversity in P-limited cover

Farming activity severely impacts the invertebrate food resources of farmland birds, with direct mortality to populations of above-ground arthropods thorough mechanical damage during crop harvests. In this study we assessed the effects of phenological periods, including the timing of harvest, on the composition and biomass of prey consumed by three species of aerial insectivorous birds. Common Swifts Apus apus, Barn Swallows Hirundo rustica and House Martins Delichon urbica breed sympatrically and most of their diet is obtained from agricultural sources of invertebrate prey, especially from oil-seed rape crops. We categorized invertebrate prey into six functional groups, including oil-seed rape pests; pests of other arable crops; other crop-provisioned taxa; coprophilous taxa; and taxa living in non-crop and mixed crop/non-crop habitats. Seasonality impacted functional groups differently, but the general direction of change (increase/decrease) of all groups was consistent as indexed by prey composition of the three aerial insectivores studied here. After the oil-seed rape crop harvest (mid July), all three species exhibited a dietary shift from oil-seed rape insect pests to other aerial invertebrate prey groups. However, Common Switfts also consumed a relative large quantity of oil-seed rape insect pests in the late summer (August), suggesting that they could reduce pest insect emigration beyond the host plant/crop. Since these aerially foraging insectivorous birds operate in specific conditions and feed on specific pest resources unavailable to foliage/ground foraging avian predators, our results suggest that in some crops like oil-seed rape cultivations, the potential integration of the insectivory of aerial foraging birds into pest management schemes might provide economic benefits. We advise further research into the origin of airborne insects and the role of aerial insectivores as agents of the biological control of crop insect pests, especially the

Low level impurities in imported wheat are a likely source of feral transgenic oilseed rape (Brassica napus L.) in Switzerland.

2015-11-01

In Switzerland, the cultivation of genetically modified (GM) oilseed rape (Brassica napus L.) and the use of its seeds for food and feed are not permitted. Nevertheless, the GM oilseed rape events GT73, MS8×RF3, MS8 and RF3 have recently been found in the Rhine port of Basel, Switzerland. The sources of GM oilseed rape seeds have been unknown. The main agricultural good being imported at the Rhine port of Basel is wheat and from 2010 to 2013, 19% of all Swiss wheat imports originated from Canada. As over 90% of all oilseed rape grown in Canada is GM, we hypothesised that imports of Canadian wheat may contain low level impurities of GM oilseed rape. Therefore, waste fraction samples gathered during the mechanical cleaning of Canadian wheat from two Swiss grain mills were analysed by separating oilseed rape seeds from waste fraction samples and testing DNA of pooled seeds for the presence of transgenes by real-time PCR. Furthermore, oilseed rape seeds from each grain mill were sown in a germination experiment, and seedling DNA was tested for the presence of transgenes by real-time PCR. GT73, MS8×RF3, MS8 and RF3 oilseed rape was detected among seed samples and seedlings of both grain mills. Based on this data, we projected a mean proportion of 0.005% of oilseed rape in wheat imported from Canada. Besides Canadian wheat, the Rhine port of Basel does not import any other significant amounts of agricultural products from GM oilseed rape producing countries. We therefore conclude that Canadian wheat is the major source of unintended introduction of GM oilseed rape seeds into Switzerland.

The effect of gene location within a crop genome on its transfer to a weed genome remains an open question for gene flow assessment. To elucidate this question, we analyzed advanced generations of intergeneric hybrids, derived from an initial pollination of known oilseed rape varieties ( Brassica napus , AACC, 2 n  = 38) by a local population of wild radish ( Raphanus raphanistrum , RrRr, 2 n  = 18). After five generations of recurrent pollination, 307 G5 plants with a chromosome number similar to wild radish were genotyped using 105 B. napus specific markers well distributed along the chromosomes. They revealed that 49.8% of G5 plants carried at least one B. napus genomic region. According to the frequency of B. napus markers (0-28%), four classes were defined: Class 1 (near zero frequency), with 75 markers covering ∼70% of oilseed rape genome; Class 2 (low frequency), with 20 markers located on 11 genomic regions; Class 3 (high frequency), with eight markers on three genomic regions; and Class 4 (higher frequency), with two adjacent markers detected on A10. Therefore, some regions of the oilseed rape genome are more prone than others to be introgressed into wild radish. Inheritance and growth of plant progeny revealed that genomic regions of oilseed rape could be stably introduced into wild radish and variably impact the plant fitness (plant height and seed number). Our results pinpoint that novel technologies enabling the targeted insertion of transgenes should select genomic regions that are less likely to be introgressed into the weed genome, thereby reducing gene flow.

Facing sexual violence in a rape emergency room: identification, projective identification, and the myth of nemesis.

PubMed

Orlandini, Alvise

2002-01-01

This article focuses on the relationship between identification and sexual abuse. Three subsequent levels are considered, namely, the relationship between (1) the abuser and the victim, (2) the gynecologist or social worker of the Rape Emergency Room (RER) and the victim, and (3) the gynecologist or social worker and the entire RER staff. In the relationship with a rape victim, the gynecologist and the social worker may perceive unexpected negative feelings such as fear, horror, impotence, despair, or even anger which can interfere in the identification with the victim. Rape can be considered also as a concrete form of devaluation through concrete penetration of the victim. As an example, a myth of sexual abuse will be presented: the rape of Nemesis by Zeus.

Soil and rape samples around Tongling mining area were collected, and their copper (Cu) contents were investigated. The results showed that the upland soil developed on the slope deposit around the mining area as well as the paddy soil distributed in lower reaches was heavily polluted by Cu, while the fluvo-aquic soil further from the mining area was less contaminated. Though the Cu content in paddy soil and upland soil was nearly the same, its bioavailability was higher in paddy soil, due to the Cu pollution of irrigated water. There was a significant correlation between available and total Cu in these three types of soil. The activation rate of soil Cu (percentage of available Cu in total Cu) was 15.0% on average, which was positively correlated with soil total Cu and organic matter while negatively correlated with soil pH and Mn. The average Cu content in rape seed and stalk was 4.0 and 5.8 mg x kg(-1), respectively. The rape Cu content increased obviously with increasing soil available Cu content when the soil available Cu content was relatively low, but the Cu absorption and accumulation by rape decreased gradually when the soil available copper content was higher than 30 mg x kg(-1).

A process for the production of the ethyl ester of winter rape [EEWR] for use as a biodiesel fuel has been studied. The essential part of the process is the transesterification of rape oil with ethanol, in the presence of a catalyst, to yield the ethyl ester of rape oil as a product and glycerin as a by-product. Experiments have been performed to determine the optimum conditions for the preparation of EEWR. The process variables were: (1) temperature, (2) catalyst, (3) rate of agitation, (4) water content of the alcohol used, and (5) the amount of excess alcohol used. Themore » optimum conditions were: (1) room temperature, (2) 0.5% sodium methoxide or 1% potassium hydroxide catalyst by weight of rapeseed oil, (3) extremely vigorous agitation with some splashing during the initial phase of the reaction and agitation was not necessary after the reaction mixture became homogeneous, (4) absolute ethanol was necessary for high conversion, and (5) 50% excess ethanol with NaOCH{sub 3} or 100% excess with KOH gave a maximum conversion. Viscosity, cloud point and pour point of the EEWR were measured. A preliminary break-even cost for the commercial production of EEWR was found to be $0.55/liter [$2.08/US gallon].« less

The Democratic Republic of the Congo has been appropriately acknowledged as "the rape capital of the world." While the country has been trapped in conflict, the use of rape as a weapon of war has been rampant and unyielding. The sexual violence inflicted upon women has been nothing less than brutal and destructive, physically, socially, and psychologically. This paper analyzes the use of rape as a weapon of war in the Congo, taking into context the ongoing war, cultural and social situations that facilitate its existence, and the many consequences the victims are forced to endure. Drawing information from various academic journals, articles, and field research from international organizations, this paper paints a concise picture of the sexual atrocities occurring in the Democratic Republic of the Congo.

A synthesis of AOT40-based response functions and critical levels of ozone for agricultural and horticultural crops

Crop-response data from over 700 published papers and conference proceedings have been analysed with the aim of establishing ozone dose-response functions for a wide range of European agricultural and horticultural crops. Data that met rigorous selection criteria (e.g. field-based, ozone concentrations within European range, full season exposure period) were used to derive AOT40-yield response functions for 19 crops by first converting the published ozone concentration data into AOT40 (AOT40 is the hourly mean ozone concentration accumulated over a threshold ozone concentration of 40 ppb during daylight hours, units ppm h). For any individual crop, there were no significant differences in the linear response functions derived for experiments conducted in the USA or Europe, or for individual cultivars. Three statistically independent groups were identified: ozone sensitive crops (wheat, water melon, pulses, cotton, turnip, tomato, onion, soybean and lettuce); moderately sensitive crops (sugar beet, potato, oilseed rape, tobacco, rice, maize, grape and broccoli) and ozone resistant (barley and fruit represented by plum and strawberry). Critical levels of a 3 month AOT40 of 3 ppm h and a 3.5 month AOT40 of 6 ppm h were derived from the functions for wheat and tomato, respectively.

The Relationship Between Television Sports Exposure and Rape Myth Acceptance: The Mediating Role of Sexism and Sexual Objectification of Women.

Rape affects a large proportion of women in the United States but is one of the most underreported crimes. It is believed that rape myth acceptance contributes to low reporting rates. We tested whether television sports exposure was indirectly related to higher acceptance of rape myth beliefs. An online survey involving 465 undergraduate students showed that viewing TV sports was positively related to hostile sexism, benevolent sexism, and sexual objectification of women. Through these variables, TV sports was indirectly and positively associated with rape myth acceptance. These results suggest that sports programming contributes to the perpetuation of rape myths in society. © The Author(s) 2016.

Rape is a pervasive social problem that causes serious physical and psychological repercussions. Rape victims' recovery is often complicated by the public's failure to believe the victim and restore justice. This study applied system justification theory to examine whether the justification of gender inequality is related to moral outrage (an emotional precursor to corrective action) and rape myth acceptance; we also examined whether rape myth acceptance is associated with moral outrage at injustice. Results showed that gender-specific system justification correlated with less moral outrage at human suffering as well as greater rape myth acceptance. The relationships between these variables were similar for men and for women, a finding that suggests that rape myths are system justifying for women. When we controlled for gender-specific system justification, rape myth acceptance correlated with less moral outrage. Results are discussed in the context of how legitimizing ideologies reduce moral outrage at injustice and perpetuate a system of sexual violence.

The attrition of rape cases from the criminal justice system (CJS) remains high and there is a paucity of research in relation to marginalized groups. Sex workers (SWs) are vulnerable to sexual violence due to the nature of their work. They are also unlikely to report such violence to police for a range of reasons. Two stages of research sought to describe the victim, perpetrator, and offense characteristics of SW rape and to examine the attrition of these cases. All rapes and attempted rapes (N = 1,146) reported to police in a large city in the South West of England over a 21-year period were examined; 67 cases involved SWs. Data were extracted from police files in line with the variables of interest. Secondary analysis of the total number of SW rapes (n = 67) resulted in a profile of these cases. A matched pairs study revealed significant differences in victim, perpetrator, and assault characteristics between SW (n = 62) and non-sex-worker (NSW) samples (n = 62). Although no significant difference was found in terms of attrition from the CJS, SW cases were observed to secure more convictions for rape than NSW cases. The implications of the findings for practice and future research are discussed. © The Author(s) 2015.

OBJECTIVE: To investigate in the South African public health sector where the best services for rape survivors were provided, who provided them, what the providers' attitudes were towards women who had been raped and whether there were problems in delivering care for rape survivors. METHODS: A cross-sectional study of facilities was carried out. Two district hospitals, a regional hospital and a tertiary hospital (where available) were randomly sampled in each of the nine provinces in South Africa. At each hospital, senior staff identified two doctors and two nurses who regularly provided care for women who had been raped. These doctors and nurses were interviewed using a questionnaire with both open-ended and closed questions. We interviewed 124 providers in 31 hospitals. A checklist that indicated what facilities were available for rape survivors was also completed for each hospital. FINDINGS: A total of 32.6% of health workers in hospitals did not consider rape to be a serious medical condition. The mean number of rape survivors seen in the previous six months at each hospital was 27.9 (range = 9.3-46.5). A total of 30.3% of providers had received training in caring for rape survivors. More than three-quarters of regional hospitals (76.9%) had a private exam room designated for use in caring for rape survivors. Multiple regression analysis of practitioner factors associated with better quality of clinical care found these to be a practitioner being older than 40 years (parameter estimate = 2.4; 95% confidence interval (CI) = 0.7-5), having cared for a higher number of rape survivors before (parameter estimate = 0.02; 95% CI = 0.001-0.03), working in a facility that had a clinical management protocol for caring for rape survivors (parameter estimate = 2; 95% CI = 0.12-3.94), having worked for less time in the facility (parameter estimate = -0.2; 95% CI = -0.3 to -0.04) and perceiving rape to be a serious medical problem (parameter estimate = 2.8; 95% CI = 1
