At-risk older adults and older survivors of sexual violence (SV) remain largely absent from SV prevention and intervention, owing to ageism and sexism, as well as other intersectional forms of prejudice, including among service providers (e.g., social workers, healthcare professionals, practitioners in SV organizations, and practitioners who serve older adults). This study explored perceptions, knowledge and experiences with SV against adults 50 years and older. Service providers who work with older adults and/or survivors were recruited, owing to where SV in later life is reported (e.g., healthcare, long-term care, and social service organizations, and to police in addition to SV service organizations), to contribute to the limited research in this area and to advance prevention and intervention. A survey was conducted on SV in later life, exploring knowledge, perceptions and experiences with SV in later life along with potential solutions for prevention and intervention among 126 service providers who worked with survivors and/or older adults. Their responses were thematically analyzed. Five themes were identified: (a) misconceptions of SV in later life and unique barriers to preventing it; (b) needs for knowledge, awareness, research and education; (c) policy and resource development; (d) victim blame and internalized stigma, and (e) ageism, intersectional prejudice and rape culture. The findings offer an in-depth understanding of barriers to prevention, and intervention, and multi-level recommendations for addressing them, which are provided by a diverse group of service providers who have worked with older adults and/or with survivors, reflecting multidisciplinary practice wisdom and experience.

This study builds on past research noting the psychosocial challenges women face in eastern Democratic Republic of Congo as survivors of rape. There is an interpretation of rape in these communities as a sexual taboo and as a danger to the families and communities of the survivors. The participants in this study described how these social norms and beliefs lead to isolation, feelings of shame, interpersonal difficulties, and hesitancy to seek medical and psychological treatment. In this study, we used a qualitative research methodology to investigate the subjective experiences of survivors and what support they thought to be the most useful in their families and communities. Three themes emerged from the data analysis: general social practices and beliefs, social reactions and consequences of rape, and the ideal social reaction to rape. The participants shared insights into two sets of values. On the one hand, there are relationship-focused values with the potential to influence revictimizing social reactions. On the other hand, there are person-focused values with the potential to rally the community in solidarity and support for survivors. These results suggest that local communities and families are key stakeholders in creating a safe and supportive social environment necessary for the survivors’ journey to recovery. Prioritizing efforts to mitigate the conflict between relationship-focused and person-focused values is recommended. Full article

The ridge culture place planting system (RCPPS) is a promising technique for planting rapeseed that can promote the growth of rapeseed by late rice stubble, which has been widely adopted in the Yangtze River delta. To determine the optimum planting date for rape (Brassica napus L.) forage and grain yield in an intensive rice–rape rotation system, a field experiment was conducted with five transplantation dates (from 20 October to 30 November at 10 day intervals) in RCPPS. The forage/grain yield, nutrition, and growth parameters were analyzed. At podding, rape biomass yield was highest, and no significant differences were found among treatments. It was around 12.0% crude protein, 11.4% ether extract, 38.8% neutral detergent fiber, and 34.9% acid detergent fiber. In the treatments of 20 and 30 November, crude protein content increased and acid detergent fiber content decreased significantly. Compared with 20 October, the grain yield of rape transplanted in November decreased significantly by 17.2% to 22.5%. The grain yield was significantly correlated with the number of secondary branches, pods, and seeds. At the final flowering stage, rape transplanted in November had noticeably reduced leaf growth, rhizome width, and yield than 20 and 30 October. Overall, for multiple uses of rapeseed in the Yangtze River delta belt with RCPPS, it is optimal to plant in mid to late November for forage use with higher nutritional value, being coordinated with the previous rice crop, whereas late October is the appropriate planting time to obtain a higher grain yield.

Background: Rape scholarship in West Africa is growing, but studies often utilize Westernized approaches. A 2018 study using a randomized survey design assessing rape among Liberian girls incorporated modified survey design methods to improve ethical data collection relevant to the cultural and contextual contexts. This article presents the findings of a thorough review of rape scholarship and design methods. Methods: Based on a qualitative analysis of field notes by the research team, we present lessons learned and best practices identified in the planning, pilot-testing, and implementation phases of the 2018 Liberian study. Results: This study helps inform innovative design methods striving to (1) avoid using obtrusively graphic language or labels prevalent in westernized studies, (2) authentically collaborate with African experts to adapt strategies to be culturally appropriate and contextually relevant, and (3) create respectfully transparent interactions with respondents and communities. Extensive research preparation and inclusive regional expertise inform compassionate methodological techniques, yielding improved Afro-centric participant experience, low participant attrition, and quality data use in policymaking. (4) Conclusions: This article offers innovative design methods to study rape, placing context, culture, and participants at the heart. Authentic collaboration with national-level experts is vital for conducting more reliable and ethical field research in the African region. Full article

Brassica napus is a species of high agronomic interest, used as a model to study different processes, including microspore embryogenesis. The DH4079 and DH12075 lines show high and low embryogenic response, respectively, which makes them ideal to study the basic mechanisms controlling embryogenesis induction. Therefore, the availability of protocols for genetic transformation of these two backgrounds would help to generate tools to better understand this process. There are some reports in the literature showing the stable transformation of DH12075. However, no equivalent studies in DH4079 have been reported to date. We explored the ability of DH4079 plants to be genetically transformed. As a reference to compare with, we used the same protocols to transform DH12075. We used three different protocols previously reported as successful for B. napus stable transformation with Agrobacterium tumefaciens and analyzed the response of plants. Whereas DH12075 plants responded to genetic transformation, DH4079 plants were completely recalcitrant, not producing any single regenerant out of the 1784 explants transformed and cultured. Additionally, an Agrobacterium rhizogenes transient transformation assay was performed on both lines, and only DH12075, but no DH4079 seedlings, responded to A. rhizogenes infection. Therefore, we propose that the DH4079 line is recalcitrant to Agrobacterium-mediated transformation. Full article

Oilseed rape (Brassica napus L.), an important oil crop of the world, suffers various abiotic stresses including salinity stress during the growth stage. While most of the previous studies paid attention to the adverse effects of high salinity stress on plant growth and development, as well as their underlying physiological and molecular mechanisms, less attention was paid to the effects of moderate or low salinity stress. In this study, we first tested the effects of different concentrations of NaCl solution on the seedling growth performance of two oilseed rape varieties (CH336, a semi-winter type, and Bruttor, a spring type) in pot cultures. We found that moderate salt concentrations (25 and 50 mmol L⁻¹ NaCl) can stimulate seedling growth by a significant increase (10~20%, compared to controls) in both above- and underground biomasses, as estimated at the early flowering stage. We then performed RNA-seq analyses of shoot apical meristems (SAMs) from six-leaf-aged seedlings under control (CK), low (LS, 25 mmol L⁻¹), and high (HS, 180 mmol L⁻¹) salinity treatments in the two varieties. The GO and KEGG enrichment analyses of differentially expressed genes (DEGs) demonstrated that such a stimulating effect on seedling growth by low salinity stress may be caused by a more efficient capacity for photosynthesis as compensation, accompanied by a reduced energy loss for the biosynthesis of secondary metabolites and redirecting of energy to biomass formation. Our study provides a new perspective on the cultivation of oilseed rape in saline regions and new insights into the molecular mechanisms of salt tolerance in Brassica crops. The candidate genes identified in this study can serve as targets for molecular breeding selection and genetic engineering toward enhancing salt tolerance in B. napus. Full article

This article focuses on sexual violence and the learned fear of rape experienced by women in their use of public space, understood as social constructions of a system of domination. We analyze a series of data, drawn from secondary sources, on the prevalence and perception of sexual assault in public space. This data confirms that sexual assault in public spaces is a real risk and that, as such, it is perceived and experienced by the majority of women. We have also selected and presented a series of institutional initiatives aimed at preventing sexual assaults on women in public spaces at night-time. Finally, we have constructed an index to study whether the selected institutional responses respond to practical gender needs or to strategic gender interests. The article concludes that all of these initiatives have a greater impact in the area of gender needs, but they are not able to reverse the structural causes of sexual assault or to contribute to true social change.

Proteases, catalysing protein hydrolysis, and arylsulfatases, catalysing sulfate-ester hydrolysis, are key microbial enzymes for N and S mineralization in soil. However, knowledge gaps remain regarding the effect of crop successions and seasonal and interannual meteorological variations on microbial communities responsible for those activities. Here, we compared the effect of six cropping sequences on the abundance and activity of microbial communities involved in proteolysis and sulfate-ester hydrolysis in northern France over four years, with two sampling dates per year. Crop sequences impacted soil microbial communities involved in proteolysis but not those involved in sulfate-ester hydrolysis. Oilseed rape following wheat presented a higher abundance of fungal 18S rDNA, culturable bacteria and alkaline metalloprotease genes and higher protease activity than other crop sequences (wheat following oilseed rape or pea, barley following wheat and pea following barley). Net N and S mineralization was not impacted by the cropping sequence. However, interannual variability of microbial parameters was large, and largely overcame the effect of crop sequences. Precipitation variability between years was the likely cause of this effect. In conclusion, the interaction between current crop, previous crops and yearly meteorology can strongly impact the soil microbial communities in agroecosystems. Full article

Every year, 7.3 million girls become pregnant before they turn 18. Teenage pregnancy increases when girls are denied the right to make decisions about their sexual health and well-being, which is a gender equality issue. Among the challenges of gender equality are those expectations that communities have about girls and early motherhood, sexual violence, and rape. Another challenge is the early marriages of children to older men coupled with the unique risks faced by these girls during pregnancy, for example, the interruption of their education, health risks, such as HIV, premature birth, and increased maternal mortality, denying the girls the right to live a healthy life. This study sought to explore the experiences of adolescent girls regarding teenage pregnancy in the rural villages of the Mopani District, Limpopo. A descriptive, explorative, and qualitative design was followed to collect data from 20 pregnant teenagers in a 13–19 years-old age group. A nonprobability purposive sampling method was used to select the participants from the three villages of the Mopani District. The data were collected using an in-depth individual interview. Tesch’s eight steps of data analysis were also applied. The study findings reveal several factors that explain the high rates of teenage pregnancy in rural Limpopo. Among these are the socioeconomic and cultural factors that predispose teens to pregnancy. The consequences of teenage pregnancy were expressed in terms of regret and ill health. Full article

A fungal strain (JC-1) of Simplicillium was isolated from a pod of oilseed rape (Brassica napus) infested with the blackleg pathogen Leptosphaeria biglobosa. This study was done to clarify its taxonomic identity using morphological and molecular approaches, to characterize its antifungal activity through bioassays and genome-based identification of antifungal metabolites, and to determine its efficacy in inducing systemic resistance (ISR) in oilseed rape. The results showed that JC-1 belongs to Simplicillium lamellicola. It displayed a strong antagonistic relationship with L. biglobosa, Botrytis cinerea (gray mold) and Sclerotinia sclerotiorum (stem rot). The cultural filtrates of JC-1 showed a high efficacy in suppressing infection by S. sclerotiorum on detached leaves of oilseed rape. Genome analysis indicated that JC-1 has the capability of producing multiple antifungal metabolites, including aureobasidin A1, squalestatin S1 and verlamelin. Inoculation of JC-1 on seeds of oilseed rape caused a suppressive effect on infection by L. biglobosa on the cotyledons of the resulting seedlings, suggesting that JC-1 can trigger ISR. Endophytic growth, accumulation of anthocyanins, up-regulated expression of CHI (for chalcone isomerase) and PR1 (for pathogenesis-related protein 1), and down-regulated expression of NECD3 (for 9-cis-epoxycarotenoid dioxygenase) were detected to be associated with the ISR. This study provided new insights into the biocontrol potential and modes of action of S. lamellicola. Full article

There is limited literature on anti-sexual violence programming on college campuses for historically underrepresented groups in the United States, including, and especially, for Muslim students. This study will explore the following questions: (a) What is Muslim students’ awareness of sexual violence on college campuses? (b) What are Muslim students’ attitudes towards sexual violence?, and (c) What challenges do Muslim survivors and allies of sexual violence face on college campuses? A mixed methods analysis of quantitative (n = 91) and qualitative data (n = 8) was utilized to understand the impact of anti-sexual violence advocacy programming on college campuses. Results demonstrate that Muslim women reported knowing more survivors of sexual assault than Muslim men. Women also reported significantly higher levels of disagreement with victim-blaming statements compared to men. Qualitative interviews with eight student leaders demonstrated challenges to sexual assault programming on campus, include Islamophobia, power struggles between student groups, denial that sexual violence is a problem, and a lack of engagement from men. Results from this study highlight several key findings including (1) rape culture attitudes vary significantly between Muslim men and Muslim women, (2) barriers to facilitating sexual violence programming include several systems of oppression, and (3) the urgent need to provide nuanced programming to support minoritized youth communities on college campuses.

Background: The child psychiatry unit of the Cochin Hospital in Paris is specialized in a transcultural clinical approach and treatment of psychotraumatism. The clinical demands addressed to the service often combine several levels of vulnerability: recent migration, repeated and intentional traumas, isolation and breach in family bonds sometimes precarious living conditions. Mastering how to approach trauma content adapting to the person’s temporality while taking into account the individual, family and collective dimensions, is a key driver to the clinical intervention (of our approach). Objective and method: We describe a paradigmatic clinical situation articulating its multidimensional complexity: the case of Céline, a 16-year-old Mozambique teenager, unaccompanied minor (UM), who arrived in France three years ago with her 4-year-old child born out of rape. They are both cared for by Paris Child Welfare Bureau. The authors used the CARE guidelines for a rigorous approach to clinical case writing. Results and discussion: In the clinical discussion, we highlight the pertinence of transcultural abilities for the treatment of a complex PTSD (post-traumatic stress disorder). We describe the measures taken to adapt the clinical interview framework to the mother’s psychic temporality, while negotiating what can be said in attendance of the child. The idea of tranquility is primordial—whether she decides to tell or not tell the child. Removing the pressure to have to tell is an element of treatment. Conclusion: Working through a progressive narrative construction, the therapeutical process allowed for the restoration of multiple levels of continuity between times prior to the trauma and following it, as well as prior to migration and following it, to create a continuum from adolescence to adulthood. Restoring narrativity favors the process of becoming a mother and the one of negotiating this new identity. The therapeutic axes also focused on improving the well-being of the UM-mother and preventing the impacts of transgenerational trauma transmission to the child. For women with similar experiences, sharing their emotions and their stories with us makes their choice about telling their child legitimate and comfortable, regardless of the decision they make.

Commercially produced black soldier flies (Hermetia illucens) represent a promising fish meal substitute, particularly in the context of using agricultural by-products and waste. Here, the culture of Hermetia maggots on five selected substrates (potato protein (P) as a by-product of starch production, rapeseed oil cake (R) from rape oil production, maize silage (M), soybean (S) meal and, as a control, concentrated chicken feed (C)) were evaluated, assessing the growth performance of Hermetia maggots related to the overall production and the nutritional composition of the respective meal. Subsequently, their use as ingredients in aquafeed formulations was evaluated in a feeding trial with juvenile Nile tilapia Oreochromis niloticus, assessing the growth performance of the fish. Substrates used for Hermetia culture significantly affected the growth and development of the maggots, revealing substantial differences in the meal quality. Still, if incorporated in isonitrogenous and isocaloric diets (33% crude protein, 21–22 MJ/kg) replacing 75% of the fishmeal protein in the formulated diets, no significant differences in growth performance of the fish were observed compared to the fishmeal control. As a conclusion, substrates clearly affect the production yield and the composition of maggots. Nevertheless, this can be compensated by feed formulation as demonstrated by the feeding trial.

This article presents the results of research on the possibilities of fragmentation of cultural, and especially agricultural, landscapes in a selected locality in eastern Slovakia, which is currently characterized by a high proportion of large-scale soil units used for growing cereals and crops subsequently used as energy sources (maize and oilseed rape, among others). Slovakia, as the country with the largest average field area in the European Union (EU), is facing a process of fragmentation of these units to counter climate change and increase the resilience of the landscape to erosion, soil fertility, and biodiversity loss. This paper presents a fragmentation method based on the restoration of former dividing lines, mainly formed by dirt roads, based on the historical mapping. The results show that in this way it is possible to achieve denser landscape fragmentation, to create dividing green belts, to increase the resilience of the environment to water and wind erosion, and to create an environment for pollinator resources and a background for plants and animals in the landscape, while respecting the ergometric routing of the dividing lines and the ownership relations of the land. Last but not least, benefits have been quantified in the form of carbon capture, as well as in the construction of a network of recreational or hiking trails. Full article

Winter oilseed rape (Brassica napus) is a global major crop used for the production of vegetable oil. Typically sown in late summer and grown throughout winter and spring, it allows for interesting cultural practices, such as frost-sensitive intercropping with companion plants. This practice not only provides nitrogen resources much needed by the crop in the spring, but companion plants can also prevent weed growth in autumn, thereby reducing common herbicide use. Additionally, intercropping has the potential to protect the crop from insect pests. During winter 2019–2020, B. napus was grown alone (i.e., as a control) or intercropped with a mixture of faba bean (Vicia faba) and grass pea (Lathyrus sativus); because of the unusually clement weather conditions, the faba bean did not freeze, which allowed for the evaluation of the impact of these companion plants on the insect pest complex in spring. Insect damage by the beetles Psylliodes chrysocephala, Ceutorhynchus napi, and Brassicogethes aeneus was assessed in both treatments. The larval density of P. chrysocephala was significantly lower in the crop grown with service plants. Egg laying and damage by C. napi were significantly reduced when B. napus was intercropped, and the number of B. aeneus captured was significantly lower in the presence of service plants than in the control. Moreover, the yield from oilseed rape was significantly higher in the part of the field with service plants than in the pure crop control. The underlying mechanisms are only partially understood, but intercropping winter oilseed rape with frost-resistant service plants seems to be an ecologically sound practice with a very high level of potential to reduce insect pest pressure and increase crop yield. This may eventually reduce our reliance on chemical inputs in one of the most treated crops. Full article
