The role of toilet hygiene in transmission of vaginal and urinary tract infections in Huis Welgemoed, CUT Campus

Published ArticleThe 2012 residents of Huis Welgemoed, a residence for female students at Central University of Technology, Free State Bloemfontein Campus have reported a high prevalence of infections of the vagina and the urinary tract. They assume that this problem is associated with poor hygienic conditions in the toilets of their residence. However, this assumption may not be entirely true, as other factors may also contribute to their problem. Previous studies have shown that there is an evident relation of vaginitis and urinary tract infections (UTI) among students and the practices of personal hygiene or the level of toilet sanitation in their residences. Especially in facilities where the students have complained about the hygiene state of their residence toilets as unsatisfactory. This preliminary study has shown that the residence conforms to the standards set out by the S.A. requirements for toilets in student housing of 1 toilet per 6 students and that the cleaning materials and methods used by staff are adequate. Interestingly, the authors have found that a lack of knowledge around UTI's and VI's regarding basic prevention strategies is most probably the cause of the high incidence of these two types of infections

Diverse pollination systems of the twin-spurred orchid genus Satyrium in African grasslands

The large terrestrial orchid genus Satyrium underwent evolutionary radiations in the Cape floral region and the grasslands of southern and eastern Africa. These radiations were accompanied by tremendous diversification of the unusual twin-spurred flowers that characterize the genus, but pollination data required to interpret these patterns of floral evolution have been lacking for grassland species in the genus. Here we document pollinators, nectar properties, and levels of pollination success for 11 grassland Satyrium species in southern and south-central Africa. Pollinators of these species include bees, beetles, butterflies, hawkmoths, noctuid moths, long-proboscid flies, and sunbirds. Most species appear to be specialized for pollination by one functional pollinator group. Long-proboscid fly pollination systems are reported for the first time in Satyrium (in S. macrophyllum and a high-altitude form of S. neglectum). Floral morphology, especially spur length and rostellum structure, differs markedly among plants with different pollinators, while nectar volume, concentration, and sugar composition are fairly uniform across species. Most taxa exhibited high levels of pollination success (>50% of flowers pollinated), a trend that can be attributed to the presence of nectar in the twin spurs

Measuring emotions in mathematics: the Achievement Emotions Questionnaire—Mathematics (AEQ-M)

Understanding the structure, antecedents, and outcomes of students’ emotions has become a topic of major interest in research on mathematics education. Much of this work is based on the Achievement Emotions Questionnaire—Mathematics (AEQ-M), a self-report instrument assessing students’ mathematics-related emotions. The AEQ-M measures seven emotions (enjoyment, pride, anger, anxiety, shame, hopelessness, boredom) across class, learning, and test contexts (internal structure). Based on control-value theory, it is assumed that these emotions are evoked by control and value appraisals, and that they influence students’ motivation, learning strategies, and performance (external relations). Despite the popularity and frequent use of the AEQ-M, the research leading to its development has never been published, creating uncertainty about the validity of the proposed internal structure and external relations. We close this gap in Study 1 (N = 781 students, Grades 5–10, mean age 14.1 years, 53.5% female) by demonstrating that emotions are organized across contexts and linked to their proposed antecedents and outcomes. Study 2 (N = 699 students, Grade 7 and 9, mean age 14.0 years, 56.9% female) addresses another deficit in research on the AEQ-M, the lack of evidence regarding the assumption that emotions represent sets of interrelated affective, cognitive, motivational, and physiological/expressive components. We close this gap by evaluating extended AEQ-M scales, systematically assessing these components for five core mathematics emotions (enjoyment, anger, anxiety, hopelessness, boredom). Our work provides solid grounds for future research using the AEQ-M to assess emotions and their components in the domain of mathematics

Renewing Criminalized and Hegemonic Cultural Landscapes

The Mafia's long historical pedigree in Mezzogiorno, Southern Italy, has empowered the Mafioso as a notorious, uncontested, and hegemonic figure. The counter-cultural resistance against the mafiosi culture began to be institutionalized in the early 1990s. Today, Libera Terra is the largest civil society organization in the country that uses the lands confiscated from the Mafia as a space of cultural repertoire to realize its ideals. Deploying labor force through volunteer participation, producing biological fruits and vegetables, and providing information to the students on the fields are the principal cultural practices of this struggle. The confiscated lands make the Italian experience of anti-Mafia resistance a unique example by connecting the land with the ideals of cultural change. The sociocultural resistance of Libera Terra conveys a political message through these practices and utters that the Mafia is not invincible. This study draws the complex panorama of the Mafia and anti-Mafia movement that uses the ‘confiscated lands’ as cultural and public spaces for resistance and socio-cultural change. In doing so, this article sheds new light on the relationship between rural criminology and crime prevention policies in Southern Italy by demonstrating how community development practice of Libera Terra changes the meaning of landscape through iconographic symbolism and ethnographic performance

Safeguarding the future of genomic research in South Africa: Broad consent and the protection of Personal Information Act No. 4 of 2013

Genomic research has been identified in South Africa (SA) as important in developing a strong bio-economy that has the potential to improve human health, drive job creation and offer potential solutions to the disease burden harboured by low- and middle-income countries. Central to the success of genomic research is the wide sharing of biological samples and data, but the true value of data can only be unlocked if there are laws and policies in place that foster the legal and ethical sharing of genomic data. The introduction and entry into force of SA's Protection of Personal Information Act (POPIA) No. 4 of 2013 is to be welcomed, but the wording of POPIA as it pertains to consent for the processing of personal information for research purposes has sparked a debate about the legal status of broad consent. We argue that a purposive interpretation of the legislation would permit broad consent for the processing of personal information for research. Although there are ongoing debates surrounding the ethical use of broad consent in Africa, the objective of this article is not to engage with the ethics of broad consent itself, but rather to focus on the legal status of broad consent for genomic data sharing under POPIA

A temporal dimension to the influence of pollen rewards on bee behaviour and fecundity in Aloe tenuior

The net effect of pollen production on fecundity in plants can range from negative – when self-pollen interferes with fecundity due to incompatibility mechanisms, to positive – when pollen availability is associated with increased pollinator visitation and fecundity due to its utilization as a reward. We investigated the responses of bees to pollen and nectar rewards, and the effects of these rewards on pollen deposition and fecundity in the hermaphroditic succulent shrub Aloe tenuior. Self-pollinated plants failed to set fruit, but their ovules were regularly penetrated by self-pollen tubes, which uniformly failed to develop into seeds as expected from ovarian self-incompatibility (or strong early inbreeding depression). Bees consistently foraged for pollen during the morning and early afternoon, but switched to nectar in the late afternoon. As a consequence of this differential foraging, we were able to test the relative contribution to fecundity of pollen- versus nectar-collecting flower visitors. We exposed emasculated and intact flowers in either the morning or late afternoon to foraging bees and showed that emasculation reduced pollen deposition by insects in the morning, but had little effect in the afternoon. Despite the potential for self-pollination to result in ovule discounting due to late-acting self-sterility, fecundity was severely reduced in artificially emasculated plants. Although there were temporal fluctuations in reward preference, most bee visits were for pollen rewards. Therefore the benefit of providing pollen that is accessible to bee foragers outweighs any potential costs to fitness in terms of gender interference in this species

Prioritising surveillance for alien organisms transported as stowaways on ships travelling to South Africa

The global shipping network facilitates the transportation and introduction of marine and terrestrial organisms to regions where they are not native, and some of these organisms become invasive. South Africa was used as a case study to evaluate the potential for shipping to contribute to the introduction and establishment of marine and terrestrial alien species (i.e. establishment debt) and to assess how this varies across shipping routes and seasons. As a proxy for the number of species introduced (i.e. 'colonisation pressure') shipping movement data were used to determine, for each season, the number of ships that visited South African ports from foreign ports and the number of days travelled between ports. Seasonal marine and terrestrial environmental similarity between South African and foreign ports was then used to estimate the likelihood that introduced species would establish. These data were used to determine the seasonal relative contribution of shipping routes to South Africa's marine and terrestrial establishment debt. Additionally, distribution data were used to identify marine and terrestrial species that are known to be invasive elsewhere and which might be introduced to each South African port through shipping routes that have a high relative contribution to establishment debt. Shipping routes from Asian ports, especially Singapore, have a particularly high relative contribution to South Africa's establishment debt, while among South African ports, Durban has the highest risk of being invaded. There was seasonal variation in the shipping routes that have a high relative contribution to the establishment debt of the South African ports. The presented method provides a simple way to prioritise surveillance effort and our results indicate that, for South Africa, port-specific prevention strategies should be developed, a large portion of the available resources should be allocated to Durban, and seasonal variations and their consequences for prevention strategies should be explored further.

Optimizing community-driven development through sage tradition in Cameroon

Powering community development requires a re-invention of traditional authority. This paper interrogates this proposition: how does sage tradition engender social resilience and what is the impact of traditional authority on the modern governance architecture? Sage tradition construed culturally as elder-led authority is anchored on wisdom and respect for elders—a pivotal asset in community development transactions. Informed by indigenous knowledge, social capital and asset-based concepts, an empirical account of strategic leadership by the elderly is proffered, uncovering indigenous governance in the North West Region, Cameroon. A pyramidal power structure validates village elders as key players in advancing social justice. They offer counsel and arbitrate in community affairs and mobilise community members for infrastructure provision—community halls, equipping schools, digging roads, building bridges and supply of fresh water. Though elder esteemed traditions prove perfunctory, findings show communities are benefiting from the accumulated, incremental cultural assets factored into local development. The paper concludes that thriving cultural assets should be amalgamated through a policy drive that taps into the utility of traditional authority, in synergy with modern state institutions to bolster social development, address poverty and social inequality
