The overall purpose of this article is to describe how the World Health Day was celebrated at the University of Namibia in 2017. University of Namibia as one of the higher institutions of learning in Namibia is celebrating the world health day yearly, mainly to promote health and prevent ill health, through partaking in the health campaigns. In 2017, the University of Namibia had conducted a mini survey and the main aims of the survey were twofold, firstly, to determine whether the students at the University of Namibia are visiting their general practitioners regularly for medical examination particular on tests like blood pressure, glucose and eye's test; and secondly to provide information about the importance of general medical check up to the students of the University of Namibia. Purposeful convenience method was used to select the sample and structural questionnaires were employed to gather data. The results revealed that the majority 34% of the students at the University of Namibia never went for medical examination to detect disease early. Recommendations were made based on the findings is that everyone to take initiative and visit any health facility (public or private) for medical examinations as soon as possible and not only to wait to be tested on world health day, since it might be too late.

Full textAbstract:
Linguistic features were used by Bishop Kleopas Dumeni of Evangelical Lutheran Church in Namibia (ELCIN) in the pre-independence era to persuade the audience to support the struggle for independence. Bishop Kleopas Dumeni used linguistic devices in an attempt to convince his target audience that the Namibians suffered a great deal at the hands of the colonial authorities. Thus international community support was desired to break the shackles of colonialism. Although Bishop Kleopas Dumeni employed various linguistic features in his speeches as a tool to whip up support for struggle for independence of Namibia, his language choices were never subjected to a critical examination to unravel their contribution to the effectiveness of the speeches. This paper thus examines how Bishop Dumeni used linguistic devices in his speeches to appeal to his audience as well as the effects these features had on the audience to support the struggle for Namibian independence. The paper is pegged on Aristotelian theory to reveal how language choice affects the three appeals of Aristotle namely, ethos, logos and pathos. Content analysis was used to deconstruct the selected speeches of Bishop Dumeni thereby identifying and evaluating the linguistic features in the speeches. The conclusion from this investigation is that Bishop Kleopas Dumeni effectively used the linguistic devices to woo his audience to his side to support in his efforts to end the wickedness of colonialism in Namibia.

"Extent, patterns and demographic correlates for physical fighting among school-attending adolescents in Namibia: examination of the 2013 Global School-based Health Survey." PeerJ 8 (May 12, 2020): e9075. http://dx.doi.org/10.7717/peerj.9075.
Full textAbstract:
Background Physical fighting is particularly detrimental for young people, often affecting other areas of their developing lives, such as relationships with friends and family and participating in risky behaviors. We aim to quantify the amount of problematic physical fighting in Namibian adolescents and identify modifiable risk factors for intervention. Methods We used the Namibia 2013 Global School-based Student Health Survey (GSHS). This survey collects health-related information on school-attending adolescents in grades 7 to 12. We defined physical fighting as having participated in at least two physical fights in the 12 months prior to responding to the survey. Factors that may be associated with physical fighting were identified a prior based on the literature and included age, sex, anxiety, suicide planning, truancy, physical activity, bullying victimization, presence of supportive parental figures, presence of helpful peers, extent of social network, and food insecurity. Multivariable logistic regression models were created to identify factors associated with physical fighting. Results A total of 4,510 adolescents were included in the study. A total of 52.7% female. 16.9% of adolescents reported engaging in at least two physical fights in the previous year. Factors associated with an increased odds of physical fighting included having a suicide plan, anxiety, truancy, food deprivation and being bullied. Increased age and loneliness were associated with a decreased odds of physical fighting. Conclusion This study identifies problematic physical fighting among adolescents in Namibia. We recommend public health and school-based programming that simultaneously targets risk behaviours and conflict resolution to reduce rates of physical fighting.

Only a single species of the trachelid spider genus Afroceto Lyle & Haddad, 2010 has been recorded from Namibia to date, A. arca Lyle & Haddad, 2010. Examination of the holotype of Argistes africanus Simon, 1910 (Liocranidae), a subadult female specimen, indicates that the species is misplaced and is hereby transferred to Afroceto as A. africana (Simon, 1910) comb. nov. Comparison of the holotype with material of Afroceto arca indicates that this latter species is a junior synonym of A. africana. New records of A. africana from South Africa and Namibia are provided, together with an updated distribution map.

Full textAbstract:
The need to re-examine Rangea has been motivated by two factors: first, by the recent progress in the understanding of three-dimensional mouldic preservation of Vendian fossils, and second, by discoveries of this taxon outside Gondwana albeit in the same sedimentary environment as seen in Namibia. Several important features are revealed, including the in situ posture in the sediment, the double-layered quilted structure, the tripartite stemless body and the mucous-supported sheath in the sediment. It is suggested that Rangea represents an infaunal organism, and that the similarity with other members of the Nama-type biota reflects convergence in functional and fabricational constraints in relation to infaunal life habit.

Full textAbstract:
The objective of this project was to develop understanding about the possibility of improving salt tolerance in pearl millet using selection and breeding methods. A collection of 143 pearl millet accessions was obtained from nineteen countries in different regions of the world, mostly from dry hot environments, e.g. Yemen, Sudan, the Central African Republic and Niger. Considerable genetic variability was found in these accessions for salt tolerance. Based upon a preliminary examination of the responses to NaCl solution in a selection of accessions, it was decided that 160 mM NaCl would be the reference parameter for assessing tolerance. The six most salt-tolerant accessions were 10876 and 10878 from Sudan, 18406 and 18570 from Namibia, and ICMV-93753 and ICMV-94474 from India, all of which had relative root lengths of above 70%. Accessions 213011 and 21351 were very sensitive, their relative root length being below 30%. Unfortunately, the areas from which the tolerant accessions from Sudan, Namibia and India originated are not known, but it is possible that they may have inhabited dry, saline lands.

Global Health Promotion 26, no. 3 (September 25, 2017): 50–61. http://dx.doi.org/10.1177/1757975917727017.
Full textAbstract:
Objectives: Breast cancer contributes substantially to morbidity and mortality in Namibia as is the case in most countries in Sub-Saharan Africa (SSA). However, there is a dearth of nationally representative studies that examine the odds of screening for breast cancer in Namibia and SSA at large. This paper aims to fill this gap by examining the determinants of breast cancer screening guided by the Health Belief Model. Methods: We applied hierarchical binary logit regression models to explore the determinants of breast cancer screening using the 2013 Namibia Demography and Health Survey (NDHS). We accounted for the effect of unobserved heterogeneity that may affect breast cancer, testing behaviours among women cluster level. The NDHS is a nationally representative dataset that has recently started to collect information on cancer screening. Results: The results show that women who have health insurance coverage (odds ratio (OR) = 1.62, p ≤ 0.01), maintain contact with health professionals (OR = 1.47, p = 0.01), and who have secondary (OR = 1.38, p = 0.01) and higher (OR = 1.77, p ≤ 0.01) education were more likely to be screened for breast cancer. Factors that influence women’s perception of their susceptibility to breast cancer such as birthing experience, age, region and place of residence were associated with screening in this context. Conclusions: Overall, the health belief model predicted women’s testing behaviours and also revealed the absence of relevant risk factors in the NDHS data that might influence screening. Overall, our results show that strategies for early diagnosis of breast cancer should be given major priority by cancer control boards as well as ministries of health in SSA. These strategies should centre on early screening and may involve reducing or eliminating barriers to health care, access to relevant health information and encouraging breast self-examination.

Full textAbstract:
The genus Micaria Westring, 1851 (Araneae, Gnaphosidae) is a group of small (1.85–5 mm) ant-like spiders that can be distinguished from other gnaphosids by their piriform gland spigots that are similar in size to the major ampullate gland spigots. According to the World Spider Catalog, there are 105 species of Micaria in the world, of which only three species are known from the African part of the Afrotropical Region, namely M. chrysis (Simon, 1910), M. tersissima Simon, 1910 and M. beaufortia (Tucker, 1923). The objectives of this study were to revise Micaria in the Afrotropical Region, providing new and updated records for each of the species, evaluating the relationships between them using COI barcoding data, and providing information on their biology, mimetic relationships and feeding ecology. These objectives were met by collecting fresh material from the KwaZulu-Natal, Western Cape, Northern Cape and Free State provinces in South Africa. Fresh material of M. tersissima and M. chrysis were collected from their type localities, Komaggas and Port Nolloth (Northern Cape Province), respectively, for identification and DNA analyses. COI sequences generated, together with those sourced from Barcode of Life Data Systems (BOLD) and GenBank, were aligned using the CulstalW alignment algorithm in the Mega X software, and molecular phylogenetic analyses were performed using MrBayes for Bayesian Inference (BI) and RaxML for maximum likelihood (ML) analyses. Morphological examination of the collected and voucher material yielded 17 new species for the Afrotropical Region, namely M. basaliducta sp. nov. (♀, ♂, South Africa), M. bimaculata sp. nov. (♀, ♂, Mauritania), M. bispicula sp. nov. (♀, ♂, Namibia, South Africa), M. durbana sp. nov. (♀, ♂, South Africa, Zambia), M. felix sp. nov. (♀, ♂, Cameroon, Ethiopia, Malawi, Mozambique, Namibia, South Africa, Zambia, Zimbabwe), M. gagnoa sp. nov. (♀, ♂, Côte d’Ivoire, Mozambique, Mozambique, Tanzania), M. koingnaas sp. nov. (♂, South Africa), M. lata sp. nov. (♂, Namibia, South Africa), M. laxa sp. nov. (♀, South Africa), M. mediospina sp. nov. (♂, South Africa), M. parvotibialis sp. nov. (♀, ♂, Senegal), M. plana sp. nov. (♀, ♂, Ethiopia), M. quadrata sp. nov. (♀, Ethiopia), M. quinquemaculosa sp. nov. (♀, ♂, Namibia, South Africa), M. rivonosy sp. nov. (♀, ♂, Madagascar), M. sanipass sp. nov. (♂, South Africa) and M. scutellata sp. nov. (♂, South Africa). Furthermore, both sexes of M. beaufortia, as well as the male of M. tersissima, are redescribed. Both sexes of M. chrysis are described for the first time, as this species was only known from a juvenile. Of the previously known species, M. beaufortia (Botswana, Ethiopia, Lesotho, Namibia, South Africa, Zimbabwe) and M. chrysis (Côte d’Ivoire, Ethiopia, Lesotho, Namibia, South Africa, Tanzania) are widespread in the Afroptropics, while M. tersissima is only known from South Africa. Both the Bayesian inference and the maximum likelihood analysess recovered Micaria (sensu lato) as monophyletic with the inclusion of the subopaca group. The pulicaria species group was recovered as polyphyletic in both the BI and ML analyses. Four Afrotropical species, as well as the M. rossica Thorell, 1875/M. foxi Gertsch, 1933 group, formed a clade sister to M. formicaria (Sundevall, 1831). Eight of the Afrotropical species now have COI barcoding data uploaded to BOLD.

Zootaxa 4318, no. 1 (September 6, 2017): 82. http://dx.doi.org/10.11646/zootaxa.4318.1.3.
Full textAbstract:
Within the genus Pedioplanis the two basal species P. laticeps and P. burchelli are phenotypically similar. In this study we examine material of both species to determine diagnostic characters and we revise the distribution of Pedioplanis laticeps. For this we used data from museum collections, literature records, as well as results from our own surveys. Careful examination of the type material of P. laticeps and P. burchelli, as well as additional specimens, confirmed several morphological characters that distinguish between the two species. A reconstruction of the taxonomic history of the species revealed that P. laticeps was described in 1845, and not in 1844 or 1849 as commonly attributed. We designate a holotype for P. burchelli, a lectotype and two paralectotypes for P. laticeps, re-describe the types of P. laticeps and P. burchelli and correct previous misidentifications. Recent literature considers P. laticeps endemic to South Africa. However, 40-year-old museum records contain specimens sampled in Namibia. Surveys in Namibia confirmed at least one extant population of P. laticeps north of the Orange River, close to an area where they were previously collected. Natural history data is very scarce for both species and a comprehensive genetic analysis, covering the entire ranges of both taxa, is urgently needed to shed light on the evolutionary history of the two sister species.

Full textAbstract:
The genus Pancratium was established by Linnaeus (1762: 417). This genus is represented by ca. 20 species, mainly distributed in the Canary Islands, West Africa, Mediterranean, and Namibia (Mabberley 2008). Hooker (1892) enumerated 6 species and Karthikeyan et al. (1989) enumerated 7 species from India. At present the genus is represented by 8 species including the newly described Pancratium nairii Sasikala & Kumari (2013: 543). Pancratium sanctae-mariae Blatter & Hallberg (1921: 52) is endemic to Western Ghats in India (Ahmedulla & Nayar, 1986). An examination of specimens at BLAT, BSI and CAL (acronyms according to Thiers 2015) and scrutiny of literature shows that the name P. sanctae-mariae is lacking nomenclatural type.

Of the dozens of conflicts in the Third World which have occurred in the post-war era, few have been of greater duration and bloodshed or have attracted the attention of as many outside actors, including the superpowers, as Angola. It has only been since the mid-1980s that the conflict began moving towards eventual settlement, with the prospects for peace often seeming to depend largely on the attitudes of Cuba, South Africa, the Soviet Union, and the United States. Further affecting the overall environment was the state of East–West relations, the internal situation in Angola, and South Africa's occupation of Namibia. A short historical background will serve as prelude to an extensive examination of the dynamics which fuelled the war in Angola for such a long period of time.

Full textAbstract:
Dryland xeric conditions exert a deterministic effect on microbial communities, forcing life into refuge niches. Deposited rocks can form a lithic niche for microorganisms in desert regions. Mineral weathering is a key process in soil formation and the importance of microbial-driven mineral weathering for nutrient extraction is increasingly accepted. Advances in geobiology provide insight into the interactions between microorganisms and minerals that play an important role in weathering processes. In this study, we present the examination of the microbial diversity in dryland rocks from the Tsauchab River banks in Namibia. We paired culture-independent 16S rRNA gene amplicon sequencing with culture-dependent (isolation of bacteria) techniques to assess the community structure and diversity patterns. Bacteria isolated from dryland rocks are typical of xeric environments and are described as being involved in rock weathering processes. For the first time, we extracted extra- and intracellular DNA from rocks to enhance our understanding of potentially rock-weathering microorganisms. We compared the microbial community structure in different rock types (limestone, quartz-rich sandstone and quartz-rich shale) with adjacent soils below the rocks. Our results indicate differences in the living lithic and sublithic microbial communities.

A 3.5-year-old wild born cheetah (Acinonyx jubatus), living in a large enclosure on a private Namibian farm, developed a large exophytic nodular neoplasm in its skin at the height of the left shoulder blade. We describe the clinical appearance, the surgical removal, and histological examination of the tumor, which was diagnosed as a moderately pigmented benign basal cell tumor. A three-year follow-up showed no evidence of recurrence after the surgery. Although neoplasia is reported in nondomestic felids, only very few concern cheetahs. So far, no case of basal cell tumor was described in this species.

A re-examination of the herbarium material has allowed to describe a new species, Corbichonia exellii, occurring in Southern Africa (Angola, Namibia and South Africa). C. exellii represents the third species in the genus. Morphological differences between all three Corbichonia species (C. decumbens, C. rubriviolacea, and C. exellii) are provided. The description of the genus is defined using the newly discovered characters (reproductive features). The taxonomy of all Corbichonia species (synonyms included) is provided, as well as maps for all species. The lectotypes of Orygia decumbens (basionym of Corbichonia decumbens) and O. mucronata (synonym of C. decumbens) are designated on specimens preserved, respectively, at BM and K. The genus Corbichonia, recently placed in Lophiocarpaceae, is markedly different from the core genus Lophiocarpus on the basis of embryological, morphological and carpological characters, and deserves further investigation concerning its taxonomic status.

The utilization of field trips in teaching and learning realizes successful and proficient learning in Social Studies. A field trip is a group excursion far from the typical teaching environment for direct understanding of a noteworthy site or place of special intrigue. This investigation in this manner was outfitted towards discovering the impacts of lack of field trips towards students’ scholastic execution in Social Studies at a selected school. A Qualitative research configuration was used for this examination. A specific school was chosen in the Zambezi Region of Namibia. The testing procedure utilized was random selection. The normal number of students chosen was 16, however just 14 students and 4 teachers partook. In light of the discoveries it was suggested among others that; teachers should take learners on field trips in order to advance and energize dynamic engagement in learning, self-inspiration, disclosure learning and learning by understanding.

Abstract This study addresses the question of how focused code-switching practices can become. It takes two complementary approaches to determine sorts and degrees of focusing, namely, a sequential analyst perspective, and a holistic perspective involving general sociolinguistic data and member’s perspectives. The case study presented involves a multilectal interaction between urban speakers of Oshiwambo, the main ethnic language of Namibia, where it cohabits with English and Afrikaans, the country’s lingua francas. The analysis reveals a range of structurally or qualitatively distinctive CS patterns involving Oshiwambo (dialects), English, and Afrikaans, used by all participants. Mostly alternational CS and specific types of backflagging display sequential regularity, while other CS patterns seem randomly distributed, at first sight an attribute of ‘free variation’. However, the examination of social indexicalities attached to the observed CS patterns shows that they all contribute to the performance of a multi-layered balancing act between urban and ethnic authenticities.

PURPOSE: The study aimed to explore and describe the knowledge of women regarding health promotion in the prevention of breast and cervical cancer. This study was carried out in the Oshakati district at the Intermediate Hospital Oshakati.
METHODOLOGY: A quantitative approach was used for this study. This approach was chosen in order to provide a comprehensive picture and understanding of the women’s knowledge or awareness of health promotion in the prevention of breast and cervical cancer. The study population consisted of all women of child-bearing age, aged 15 to 49, in the Oshakati health district, that is, 41,985. The research sample was identified as 10% of the study population, thus numbering 419 respondents. The researcher personally distributed 419 questionnaires to every second woman of child-bearing age admitted to the Intermediate Hospital Oshakati.
RESULTS: The findings indicate that awareness of information relating to breast and cervical cancer exists in Oshakati Health District. However, overall knowledge on the causes of breast and cervical cancer, risk factors for breast cancer and warning signs of cervical cancer was very poor. The findings also revealed that while many respondents were informed about breast self-examination (BSE) and had practised it, very few respondents acknowledged clinical breast examination (CBE) attendance once a year, or the use of mammography and sonar attendance as additional screening methods.
RECOMMENDATIONS & CONCLUSION: Based on the findings the study recommends that women should share information with their peers; in addition, radio should be used to disseminate such information as it is the most reliable source of information in the rural areas. Information, education and communication materials on the prevention of breast and cervical cancer should be developed and disseminated to the public. Women should be encouraged to develop a reading culture in order to increase their knowledge.

Full textAbstract:
Albuca crispa is a new species of section Falconera series Trianthera with crispulate leaves from the Great Karoo, known at least since 1947 but overlooked until now. A second new species. A grandis. from the southwestern Cape was previously included in A. fragrans Jacq. (section Falconera series Falconera). It is a robust species that flowers in winter and early spring and the styles are rugulose with ± isodiametric epidermal cells, unlike typical A. fragrans which is a more slender species flowering in early summer and with derived, smooth styles with fusiform epidermal cells. The recent discovery of a flowering population matching the type of A. albucoides (Aiton) J.C.Manning Goldblatt (subgenus Osmyne) allows for a full description and illustration of this poorly know n and taxonomically neglected species that has often been included in A. suaveolens (Jacq.) J.C.Manning Goldblatt. Lastly, examination of the type of A. reflexa Krause Dinter from Namibia shows it to be conspecific w ith Drimia indica (Roxb.) Jessop.

Full textAbstract:
Kribiodorum Kieffer, an otherwise North American and African genus of Chironomini (Diptera: Chironomidae), extends to the Oriental region through two new species. An adult male and female of Kribiodorum malicky sp. n. is newly described from Thailand, and from Brunei (Borneo) a pharate male and the pupa of Kribiodorum belalong sp. n. is described. Additionally, from Namibia (s.w. Africa) a 'manuscript' taxon is described formally with co-authorship of the late Arthur Harrison as Kribiodorum kunene sp. n. Males of the new species and the sole new pupa conform substantially to generic diagnoses based on the North American Kribiodorum perpulchrum (Mitchell). Examination of specimens of African Kribiodorum pulchrum Kieffer and N. American K. perpulchrum confirms their morphological similarity and reaffirms the junior synonymy of Stelechomyia Reiss designated for the North American species. Kribiodorum expands the number of genera of Chironomidae with African and Asian representatives, although unusual in its absence from Australia yet presence in the Nearctic.

"Factors that hinder the academic performance of the nursing students who registered as first years in 2010 at the University of Namibia (UNAM), Oshakati Campus in Oshana, Namibia." Journal of Nursing Education and Practice 7, no. 8 (March 14, 2017): 63. http://dx.doi.org/10.5430/jnep.v7n8p63.
Full textAbstract:
The University of Namibia (UNAM) is the only national university in Namibia that was established in 1992. It offers diploma and degree courses. The Bachelor of Nursing Science (Clinical) (Honours) was introduced in 2008 after the Diploma in Comprehensive Nursing Science was phased out. This degree is offered over the period of four years full-time. Students are allocated to the clinical practice throughout the training to acquire the relevant nursing skills. At the time of research the course was offered at two campuses only namely Windhoek and Oshakati. The total number of students who were admitted in 2010 was 83, but at the time of the research when they were in their fourth year, there were only 59. The difference of 24 was the students who could not make it to the fourth year and finish in the prescribed time frame. The lecturers were concerned with the poor performance of the students, the increased number of students with some modules behind, and the overcrowding of some classes. The purpose of the study was to identify, explore and describe the factors that hinder the academic performance of the nursing students at the UNAM Oshakati campus. The study was conducted among nursing students who registered for the Bachelor of Nursing Science (Clinical) (Honours) in 2010. The study was qualitative, exploratory, descriptive and contextual in nature using non-probability purposive sampling. The findings revealed that the academic performance of student nurses at the University of Namibia Oshakati campus is influenced by both internal and external factors. However, external factors are many compared to internal factors. External related factors comprise of teaching and learning, insufficient resources, lack of university accommodation, curriculum related and socio-economic factors. Teaching and learning related factors include use of one teaching strategy, language barriers, inadequate support and labeling of students by lecturers. On the other hand, insufficient resources are unavailability of the bookshop on campus, insufficient prescribed textbooks, poor internet facility, lack of space and less equipped library. Curriculum related factors include overloaded examination time table, huge scope of test, study day system and module pre-requisites, while socio-economic factors are problems in relationships, peer influence, financial problems and pregnancy while studying. Internal factors comprise of students’ attitude and lack of self-discipline among some students. Those factors result in increased number of students with some modules behind, overcrowding of some classes, increased student-lecturer ratio and some students not completing their studies within the prescribed time frame.

Full textAbstract:
The melitid amphipod genus Dulichiella Stout, 1912, is revised. Based on examination of type material or new material from near type localities, we redescribe D. anisochir (Krøyer, 1845) from Brazil, D. appendiculata (Say, 1818) from the south-eastern United States, D. australis (Haswell, 1879) from eastern Australia, D. cotesi (Giles, 1890) from the Andaman Islands, D. cuvettensis Appadoo & Myers, 2005 from Mauritius, D. fresnelii (Audouin, 1826) from the Red Sea, D. pacifica Lowry & Springthorpe, 2005 from Australasia and D. spinosa Stout, 1912 from California. Based on published illustrations and new material we describe six new species: D. guinea sp. nov. from western Africa; D. lecroyae sp. nov. from the south-eastern United States; D. oahu sp. nov. from Hawaii; D. terminos sp. nov. from south-eastern Mexico; D. tomioka sp. nov. from Japan and D. tulear sp. nov. from Madagascar. The new genus Verdeia is described for two established species, Melita grandimana Chevreux, 1908 from the Cape Verde Islands and Melita subchelata Schellenberg, 1925 from Namibia. We provide a key to the world species of these genera.

Full textAbstract:
This Special Issue aims to reflect on knowledge co-production and transdisciplinarity, exploring the mutual interaction between water governance and water research. We do so with contributions that bring examples from diverse parts of the world: Bolivia, Canada, Germany, Ghana, Namibia, the Netherlands, Palestine, and South Africa. Key insights brought by these contributions include the importance of engaging the actors from early stages of transdisciplinary research, and the need for an in-depth understanding of the diverse needs, competences, and power of actors and the water governance system in which knowledge co-production takes place. Further, several future research directions are identified, such as the examination of knowledge backgrounds according to the individual and collective thought styles of different actors. Together, the eight papers included in this Special Issue constitute a significant step toward a better understanding of knowledge co-production and transdisciplinarity, with a common thread for being reflective and clear about their complexity, and the political implications and risks they pose for inclusive, plural and just water research and governance.

Abstract Wilhelm, M. R., Roux, J-P., Moloney, C. L., and Jarre, A. 2013. Data from fur seal scats reveal when Namibian Merluccius capensis are hatched and how fast they grow. – ICES Journal of Marine Science, 70: . Scat samples were collected regularly at several breeding colonies of Cape fur seals along the Namibian coast. Merluccius capensis otoliths were obtained from these samples, identified, and measured. Cohorts were easily distinguishable using otolith length measurements converted to fish total length. Growth rates of 2- to 21-month-old hake and hatch dates for each of 15 cohorts were estimated from September 1994 to October 2009 (1994–2008 cohorts) using a Schnute growth function and a non-linear mixed-effects model. The function describing growth of these young hake was length Lt (cm) at age t (years) Lt = 3.17 + (25.0 − 3.17) × [1 − e−0.665 × (t − 0.140)]/[1 − e−0.665 × (1.74–0.140)]. Cohort-specific random effects showed a population hatch date estimate of 31 July (austral winter), varying by 94 days among cohorts, from 31 May (1996 cohort) to 1 September (2004 cohort). The mean growth rate from ages 6 to 12 months was 1.26 cm month−1 for the population, ranging between 0.97 cm month−1 (1996 cohort) and 1.38 cm month−1 (2004 cohort). As this rate is almost double the previously estimated value, which is currently used in the stock assessment models, this result may have major implications for the current stock assessment results and the management of the stock. Re-examination of growth rates needs to be extended to older fish.

Full textAbstract:
The purpose of this study was to assess the extent to which predictors of teachers’ competencies in teaching mathematics predict the outcomes of mathematics performance among learners at upper primary phase. The determinants were namely gender, teaching experience, region, qualification, and fields of study exert effect on teachers’ competencies in lesson planning and preparation, assessment and evaluation of learners, lesson delivery, the use of teaching strategies, the quality of homework, and the availability of teaching materials. The generic understanding of the impacts of predictors of teaching competencies on learners’ performance significantly informs the development of training programmes components, and teaching and learning processes across the schooling system. Shulman’s theory of teacher content and pedagogical knowledge underpinned the study. The study comprised of holistic samples of 117 mathematics teachers at upper primary phase teachers from 39 schools. The selection of three schools from each region followed three criteria, namely outstanding, moderate, and lower performances in Grade 10 examination. Data is collected from classroom observation and analysis of relevant documents. The findings show that predictor variables such as gender, teacher qualification, teaching experience, field of study, and region exerted effects on the way teachers plan and prepare the lesson, deliver the lesson, assess and evaluate learners, use the teaching materials, and the quality of work. Teachers who specialized in mathematics were more competent in mathematics teaching. The results presuppose that predictors of teachers’ competencies in teaching mathematics are essential for improving teaching and learning of mathematics in schools. The outcome of this study is beneficial to education officials who are directly responsible for coordinating the teaching of mathematics in schools and the allocation of teaching subjects, particularly mathematics. The findings showed that a number of teachers were not trained mathematics. This was an indication of the existing shortage of mathematics teachers in schools nationally. Untrained mathematics teachers negatively influenced learners’ performance. These outcomes implied that education planners at the national, regional and district levels should set up strategies on how to increase the production of mathematics teachers nationally in order to meet the demand of such teachers in schools.

Full textAbstract:
The systematic position and generic limits of Rossimyiops Mesnil, 1953 (type species: R. whiteheadi Mesnil, 1953) are critically redefined. Examination of the male terminalia allowed us to demonstrate the unjustified placement of Rossimyiops within the subfamily Dexiinae, tribe Dufouriini and its probable affiliation with the subfamily Tachininae, tribe Minthoini. The following generic names are synonymised with Rossimyiops Mesnil, 1953: Mesnilomyia Kugler, 1972 (type species: M. magnifica Kugler, 1972) syn. nov., and Persedea Richter, 2001 (type species: P. exquisita Richter, 2001) syn. nov. The following new combinations are proposed: Rossimyiops achilleae (Kugler, 1972) comb. nov., R. exquisitus (Richter, 2001) comb. nov., R. longicornis (Kugler, 1972) comb. nov., R. magnificus (Kugler, 1972) comb. nov., and R. subapertus (Herting, 1983) comb. nov. Mesnilomyia rufipes Zeegers, 2007 is established as a synonym of Persedea exquisita Richter, 2001, syn. nov. Rossimyiops austrinus Cerretti sp. nov. from Namibia and Rossimyiops djerbaensis Cerretti sp. nov. from Tunisia are described, illustrated and compared with the other known species of the genus. Male terminalia and female external morphology of R. subapertus and R. whiteheadi are described for the first time. Finally, Mesnilomyia calyptrata Zeegers, 2007 is removed from this genus and placed as Tachinidae incertae sedis.

Full textAbstract:
The gekkonid genus Goggia includes eight described species of mostly small-bodied rock dwelling gecko endemic to the southwestern portion of southern Africa, in South Africa and extreme southern Namibia. Previous studies focused on Goggia have employed external morphology and allozyme electrophoresis, but no sequence-based molecular phylogeny of the group has been produced. We have generated a molecular phylogeny of Goggia including all named species and multiple individuals within each species, using sequences of the mitochondrial gene ND2 and nuclear genes RAG1 and PDC. The phylogeny depicts a basal divergence between eastern and western species of small-bodied Goggia, with additional divergences also showing structure strongly correlated with geography. Goggia lineata and G. rupicola are shown to be non-monophyletic, and examination of external morphology supports the distinctiveness of these lineages. We describe two new species to accommodate the southern lineages of “G. lineata” and “G. rupicola”: Goggia incognita sp. nov. and Goggia matzikamaensis sp. nov. Both new species are separated from their northern relatives by geographic barriers: the Knersvlakte plain for G. incognita sp. nov. and G. lineata, and the high Kamiesberg mountains for G. matzikamaensis sp. nov. and G. rupicola. The possible roles of geography, ecology, and climate in promoting diversification within Goggia are discussed.

Full textAbstract:
The Namibian College of Open Learning (NAMCOL) conducted a dropout survey in order to determine why distance students studying with the College, drop out of the subjects they enrolled for. Information was collected from learners who dropped out of subjects they enrolled for, tutors and Head of Centres. Online and telephonic interviews were used for learners, while questionnaires in hard copies were distributed to the tutors and Head of Centres. The majority of the learners who responded to the questionnaire indicated that the learner support from the College was good and that the study materials were useful. Even so, most learners indicated that job commitments, financial issues and sickness were the main reasons why they dropped out of the subjects they enrolled for. The subject that had the highest dropout rate for both grade 10 and 12, were English. Other reasons given by tutors and head of centres as to why they think learners drop out of subjects include lack of motivation from learners, lack of competency in English and some learners find employment or register at private institutions, centres are far from the learners. Some of the recommendations given by tutors and head of centres to reduce dropouts the College should decentralise the centres, clear, persistent and continuous information regarding examination dates, collecting timetables and venues should be given.

Full textAbstract:
This is the last in a series of systematic accounts of the 60 worldwide species of the littorinid genus Echinolittorina. The taxonomy and distributions of molluscs in the eastern Atlantic are poorly known and littorinids are no exception. Recent molecular studies have clarified the number of species and their relationships, and are used as the basis of this systematic account. Detailed morphological descriptions are provided here for the eight known living species in the tropical and warm temperate eastern Atlantic, from the Mediterranean to Namibia, including the islands of Cape Verde, Canaries, São Tomé, Ascension and St Helena. The descriptions give details of shell, operculum, pigmentation of headfoot, reproductive anatomy, spermatozoa, egg capsules and radulae. Diagnoses include reference to mitochondrial gene sequences (COI). A key is based on shell, penial shape, pallial oviduct and geographical distribution, and includes all other littorinid species (members of genera Tectarius, Afrolittorina, Littoraria, Melarhaphe and Littorina) found in the eastern Atlantic region. Three new species are described: E. peregrinator, E. caboverdensis and E. soroziczac. One name change is proposed: Littorina lemniscata Philippi, 1846 was formerly listed as a junior synonym of E. miliaris from Ascension Island, but examination of types has shown this to be a senior synonym of E. galapagiensis (Stearns, 1892) from the tropical eastern Pacific, which should now be called E. lemniscata. Full synonymies are given for all taxa, and the taxonomic, evolutionary and ecological literature reviewed. Distribution maps are based on examination of 312 samples and on reliable literature records. These reveal close correspondence with the biogeographic division of the region into three provinces (Lusitanian; West African; St Helena and Ascension). The allopatry of sister taxa is maintained by barriers of ocean currents, river deltas and distribution of continental and oceanic conditions. The eight species belong to four clades (E. peregrinator; E. soroziczac; E. punctata group; E. granosa group), each of which is sister to one or more species from the western Atlantic or belongs to a clade with western Atlantic and eastern Pacific distribution. This supports trans-Atlantic dispersal from the west, estimated to have occurred in the Early Miocene and in the Plio-Pleistocene.

Full textAbstract:
Three new species of Gladiolus L. are described from South Africa. G. dolichosiphon is the second known member of series Blandus from the mountains of the Little Karoo in Western Cape, and is distinguished from other members of the long tubed, pink-flowered G. carneus complex by its 5 or 6 linear leaves, creamy pink to salmon flowers with a tube 30-50 mm long and longer than the dorsal tepal, and its late summer flowering. G. karooicus from the Klein Roggeveld and the northern foothills of the Witteberg, is a spring-flowering species allied to G. permeabilis but has bright, canary-yellow flowers with the lower part of the lower tepals involute and conspicuously auriculate. G. reginae is an edaphic endemic of the Sekhuk- huneland Centre of Floristic Endemism in Mpumalanga, and flowers in autumn. It is evidently a glabrous member of section Densiflorus series Scabridus, distinguished by its long-tubed flowers, streaked with red on the lower tepals and blotched with red in the throat. Anomalously, however, it has the tubular inner bracts and large capsules diagnostic of section Ophiolyza series Oppositiflorus. A re-examination of the morphology suggests that series Scabridus is better placed in section Ophiolyza and a slightly revised classification of Gladiolus in southern Africa is proposed. We also propose the replacement name G. sulculatus for the Tanzanian species, G. sulcatus Goldblatt, a later homonym of G. sulcatus Lam. Finally, a recent sighting of what appears to be G. rubellus from northern Namibia constitutes the first record of this species in the country and a major range extension from its previous known occurrence in southeastern Botswana.

Full textAbstract:
Abstract This study documents the global distribution and characteristics of diurnally varying low-level jets (LLJs), including their horizontal, vertical, and temporal structure, with a special emphasis on highlighting the underlying commonalities and unique qualities of the various nocturnal jets. Two tools are developed to accomplish this goal. The first is a 21-yr global reanalysis performed with the fifth-generation Pennsylvania State University–NCAR Mesoscale Model (MM5) using a horizontal grid spacing of 40 km. A unique characteristic of the reanalysis is the availability of hourly three-dimensional output, which permits the full diurnal cycle to be analyzed. Furthermore, the horizontal grid spacing of 40 km better resolves many physiographic features that host LLJs than other widely used global reanalyses. This makes possible a detailed examination of the systematic onset and cessation of the jets, including time–height representations of the diurnal cycle. The second tool is an index of nocturnal LLJ (NLLJ) activity based upon the vertical structure of the wind’s temporal variation, where the temporal variation is defined in local time. The first available objectively constructed global maps of recurring NLLJs are created from this index, where the various NLLJs can be simultaneously viewed at or near their peak time. These maps not only highlight all of the locations where NLLJs are known to recur, but they also reveal a number of new jets. The authors examine the basic mechanisms that give rise to the NLLJs identified in four disparate locations, each having a profound influence on the regional climate. The first, the extensively studied Great Plains NLLJ, is used to confirm the veracity of the global analysis and the index of NLLJ activity. It also provides context for three of the many newly identified NLLJs: 1) Tarim Pendi in northwest China; 2) Ethiopia in eastern Africa; and 3) Namibia–Angola in southwest Africa. Jets in these four regions illustrate the variety of physiographic and thermal forcing mechanisms that can produce NLLJs.

Full textAbstract:
A recent cataloguing of the Heteroptera (Hemiptera) types held in the collection of National Museum, Prague (NMPC), revealed several specimens originating from the collection of Czech collectors Emil Holub and Ladislav Duda, being part of the same series as types described by Géza Horváth in his paper ‘Hemiptera nova africana’ and until now believed to be deposited exclusively in the Hungarian Natural History Museum, Budapest (HNHM). The publication date of that paper is fixed as March 20, 1893, affecting these taxa: Reduviidae: Coranopsis Horváth, 1893, Coranopsis vittata Horváth, 1893, Cosmolestes fulvus Horváth, 1893, Edocla albipennis Horváth, 1893, Harpactor (Diphymus) dudae Horváth, 1893, Oncocephalus angustatus Horváth, 1893, Phonoctonus validus Horváth, 1893, Reduvius reuteri Horváth, 1893, Staccia inermis Horváth, 1893; Blissidae: Ischnocoridea Horváth, 1893, Ischnocoridea elegans Horváth, 1893; Rhyparochromidae: Aphanus (Graptopeltus) dilutus Horváth, 1893 [= Naphiellus dilutus (Horváth, 1893)], Pamera bergrothi Horváth, 1893 [= Horridipamera bergrothi (Horváth, 1893)]; Coreidae: Homoeocerus fuscicornis Horváth, 1893, Hypselonotus balteatus Horváth, 1893 [= Hypselonotus interruptus Hahn, 1833]; Plataspidae: Niamia Horváth, 1893, Niamia angulosa Horváth, 1893; Scutelleridae: Cantao africanus Horváth, 1893, Cryptacrus princeps Horváth, 1893 [= Cryptacrus comes comes (Fabricius, 1803)], Polytodes Horváth, 1893 [= Polytes Stål, 1867], Polytodes ochraceus Horváth, 1893 [= Polytes tigrinus (Vollenhoven, 1868)]; Dinidoridae: Dinidor vicarius Horváth, 1893; Pentatomidae: Caura modesta Horváth, 1893, Diploxys (Paracoponia) holubi Horváth, 1893 [= Coponia holubi (Horváth, 1893)], Paracoponia Horváth, 1893 [= Coponia Stål, 1865], Mecosoma spinosum Horváth, 1893 [= Macrorhaphis acuta Dallas, 1851], Menida distanti Horváth, 1893 [= Menida transversa transversa (Signoret, 1861)], and Stollia crucifera Horváth, 1893. Only the following type specimens bearing Horváth’s original type label and deposited in HNHM are recognized and their status elucidated: Coranopsis vittata (1 syntype), Cosmolestes fulvus (holotype), Edocla albipennis (holotype), Harpactor (Diphymus) dudae (1 syntype), Oncocephalus angustatus (1 syntype), Reduvius reuteri (1 syntype), Homoeocerus fuscicornis (1 syntype), Hypselonotus balteatus (1 syntype), Niamia angulosa (1 syntype), Cryptacrus princeps (1 syntype), Polytodes ochraceus (holotype), Dinidor vicarius (holotype), Caura modesta (lectotype), Diploxys (Paracoponia) holubi (lectotype), and Menida distanti (1 syntype). The syntype(s) of Cantao africanus and holotype of Stollia crucifera could not be located; a specimen in NMPC presumably from the same series is designated here as neotype of Stollia crucifera. Based on the examination of the type material the following subjective synonymies are proposed: Neotrichedocla quadrisignata (Stål, 1855) = Reduvius reuteri Horváth, 1893, confirmed synonymy; Dinidor impicticollis Stål, 1870 = D. vicarius Horváth, 1893, syn. nov.; Parantestia (Chromantestia) cincticollis (Schaum, 1853) = Parantestia (Chromantestia) modesta (Horváth, 1893), syn. nov. = Parantestia (Chromantestia) cincticollis var. bergrothiana Kirkaldy, 1909, syn. nov.; Cosmopepla cruciaria Stål, 1872 = Stollia crucifera Horváth, 1893, syn. nov. Rhynocoris katangensis Schouteden, 1929 (Reduviidae), erroneously considered as junior synonym of Rhynocoris dudae by MALDONADO CAPRILES (1990), must be considered valid species. Type locality of the species described based on material collected by Emil Holub is discussed.

Full textAbstract:
A review of the genera Othonna and Senecio undertaken for the forthcoming Greater Cape plants 2: Namaqualand-southern Namib and western Karoo (Manning in prep.) led to a re-examination of the taxonomic status of several species. This was facilitated by the recent availability of high-resolution digital images on the Aluka website (www.aluka.org) of the Drege isotypes in the Paris Herbarium that formed the basis of many species described by De Candolle in his Prodromus systematis naturalis regni vegetabilis. These images made it possible to identify several names whose application had remained uncertain until now. Each case is briefly discussed, with citation of additional relevant herbarium specimens. The following species are reduced to synonomy: O. incisa Harv. is included in O. rosea Harv.; O. spektakelensis Compton and O. zeyheri Sond. ex Harv. are included in O. retrorsa DC.; S. maydae Merxm. is included in S. albopunctatus Bolus, which is now considered to include forms with radiate and discoid capitula; S. cakilefolius DC. is included in O. arenarius Thunb.; S. pearsonii Hutch, is included in O. aspertdus DC.; S. parvifolius DC. is included in S. carroensis DC.; S. eriobasis DC. is included in S. erosus L.f.; and S. lobelioides DC. is included in S. flavus (Decne.) Sch.Bip. The name S. panduratus (Thunb.) Less, is identified as a synonym of S. erosus L.f. and plants that are currently know n under this name should be called S. robertiifolius DC. The confusion in the application o f the names O. perfoliata (L.f.) Jacq. and O. filicaulis Jacq. is examined. O. perfoliata is lecto- typified against a specimen in the Linnaean Herbarium (LINN) w ith radiate capitula. The name O. filicaulis correctly applies to a radiate species and is treated as a synonym of O. perfoliata. The vegetatively similar taxon with disciform capitula that is currently known as O. filicaulis should be known as () undulosa (DC.) J.C.Manning Goldblatt, comb. nov. The new name O. daucifolia J.C.Manning Goldblatt is provided to replace the later homonym O. abrotanifolia (Harv.) Druce.

Full textAbstract:
The black-footed cat (Felis nigripes), a diminutive spotted cat whose native habitat is arid grasslands in South Africa, Namibia and Botswana, is classified as vulnerable by the International Union for Conservation of Nature and is listed as CITES Appendix I. They are perhaps the rarest of the African cats and their status is threatened by habitat deterioration and poisoning from ingestion of baited carcasses intended for other species of cats. Here, we examined (1) ovarian response of black-footed cat females to exogenous gonadotropin stimulation, (2) in vitro production of embryos by IVF with cooled vs cryopreserved sperm and (3) in vivo developmental ability of in vitro–derived embryos. Six females, 1.5 to 2.5 years of age at first treatment, were administered a total of 3.0 to 3.6 IU of porcine FSH (IM; Sioux Biochemical Co., Sioux City, IA) daily over 4 days. On Day 5, 3.0 (n = 12) or 5.0 (n = 2) IU of porcine LH (IM; Sioux Biochemical Co.) was given and laparoscopic oocyte retrieval (LOR) was done 24 h later. One, two, three, or four LOR were done on 1, 3, 1 and 1 females, respectively (total = 14 LOR). The average age at LOR was 3.3 years (range = 1.5–7.5 years). Semen was obtained by electroejaculation of 3 males (1.5, 6.0, 7.5 years). Anaesthesia for LOR and electroejaculation was induced and maintained, after intubation, with 5 and 2.5% isoflurane, respectively. Sperm samples were used after storage at 4°C for 24 h (TEST yolk, TY) or after cryopreservation (TY + 6% glycerol). Luteal tissue was present on the ovaries at 4 of 5 LOR done during January to May as compared with none of 9 LOR done from June to December. Of 165 oocytes (mean = 11.8) recovered, 38/54 (70%) and 50/106 (47%) underwent cleavage after IVF with cooled or cryopreserved sperm, respectively (P < 0.01, chi-square). None of 5 oocytes cleaved after intracytoplasmic sperm injection with cryopreserved sperm. Procedures for in vitro embryo production were as described previously (Gómez et al. 2006 Theriogenology 66, 72–81; Pope et al. 2006 Theriogenology 66, 1518–1524). Four laparoscopic oviducal embryo transfer procedures were done on Day 1: 2 recipients received fresh Day 2 embryos (n = 5, 8) and 2 recipients received embryos that had been cryopreserved on Day 1 (n = 6) or 2 (n = 8) at a slow, controlled rate in 1.4 M of propylene glycol/0.125 M of sucrose/10% dextran 70. Each recipient (1.75 to 4.5 years) had undergone LOR on Day 0 (5–19 oocytes recovered). Upon ultrasonographic examination on Day 50, a 2.3-year-old recipient of cryopreserved embryos was determined to be pregnant. She delivered 2 live male kittens, without assistance, on Day 69. When first examined at 15 days of age, the kittens weighed 156 and 198 g. At 5 months, their weights were 1.62 and 1.81 kg. The sperm sample used to produce the embryos (in 2005) that resulted in the births of kittens (in 2011) was collected from a male at the Henry Doorly Zoo, Omaha, NE (in 2003), extended and transported overnight at 4°C to New Orleans, LA, before cryopreservation. In summary, we have further demonstrated that assisted reproductive technology can be used for conservation of rare and vulnerable small felids.

Full textAbstract:
Amnesty laws issued by Administrator General Pienaar in 1989 and 1990 still show their effect by preventing prosecutions and investigations of situations that occurred before Namibia’s independence. Unlike South Africa, Namibia did not establish a truth-finding body such as the Truth and Reconciliation Commission. The result is a situation of silence, oblivion and impunity without any kind of accountability. On this basis, crimes such as international crimes or serious human rights violations have never been prosecuted or even investigated. As this article argues, the amnesty laws from 1989 and 1990 qualify as blanket amnesties. Up until today, Namibians as well as the members of the South African Defence Force benefit from those amnesties. Against this backdrop, the question of whether the Namibian blanket amnesties apply in relation to international crimes and grave human rights violations will be addressed. This article argues that based on international law, the application of the Namibian blanket amnesties can be challenged in a potential criminal case that deals with international crimes or grave human rights violations in the Namibian courts. Therefore, this article illustrates how international law applies in the Namibian legal system. In this context, Namibia follows a monist approach which makes it quite receptive of international law and international standards. On this basis, this article points out binding international law at the time before and after Namibia’s independence as well as examining Namibia’s binding treaty obligations which arise under the Geneva Conventions, Torture Convention and the International Covenant on Civil and Political Rights. In the next section, an examination of domestic and international jurisprudence lays the foundation for the argument that the Namibian blanket amnesties can be challenged in a Namibian court when the crimes in question constitute international crimes, such as crimes against humanity or war crimes.

Full textAbstract:
Background: Botryococcus braunii is well known from all continents, but it has been sparsely recorded from Africa compared to other continents. The alga recently formed a rusty orange-red bloom in the Tilda Viljoen Dam, situated near Gobabis in Namibia. Blooms of this species are known to produce allelopathic substances that inhibit the growth and diversity of other phytoplankton, zooplankton and fish.Objectives: The objective of this study was to record the presence of B. braunii in Namibia.Method: Morphological features of the species were compared with illustrations and literature on B. braunii found in other continents of the world, particularly North America and Europe. Extensive literature surveys revealed its currently known geographical distribution.Results: The organism responsible for the discolouration of the water was identified as B. braunii. Microscopic examination revealed large colonies that floated in a thick layer on the surface of the water. Literature searches on the geographical distribution of B. braunii revealed that this was the first record of this species’ presence in Namibia.Conclusion: The known geographical distribution of B. braunii was expanded to include Namibia.

Full textAbstract:
The described Afrotropical species of the genus Hexophthalma Karsch, 1879 (under the genus name Sicarius Walckenaer, 1847), of the spider family Sicariidae Keyserling, 1880, were recently reviewed. In the present paper the Afrotropical species of the genus Hexophthalma are revisited. After a thorough examination of all the available specimens from nine major collections, the species H. testacea (Purcell, 1908) is here synonymized with H. hahni (Karsch, 1878), three new species are described – H. binfordae sp. nov., H. goanikontesensis sp. nov. (both from Namibia) and H. leroyi sp. nov. (from South Africa) – and the male of H. dolichocephala (Lawrence, 1928) is described for the first time. The distribution of the species is also revised and a new updated key to the species is compiled.

Full textAbstract:
The spermatozoon morphology of 19 species of Indo-Pacific, East Atlantic and M editerranean patellid limpets was examined by transmission electron microscopy. All nine species of Patella and Helcion from the South Atlantic (southern Africa) and the Indo-Pacific, as well as three species from the North Atlantic, have sperm which correspond to one of the sperm groups I, II or III, previously described for patellacean limpets from southern Africa (Hodgson & Bernard 1988). With the exception of P. safiana and P. canescens , all 7 Patella species from the N.E. Atlantic/Mediterranean have sperm morphologies which closely resemble one another but are distinctly different from the sperm types of species in the southern hemisphere. These N.E. Atlantic/Mediterraean limpets have been assigned to a new sperm group, group VI. On the basis of sperm structure it is suggested that patellid limpets had three main centres of radiation: a N.E. Atlantic/Mediterranean centre; an East Atlantic centre with its focal point on the S.W. coast of southern Africa; an Indo-Pacific centre with its focal point on the S.E. coast of South Africa. Despite similarities between the species within groups, each has a unique sperm. An examination of spermatozoa of one patellid from Namibia and one from S. Angola (both initially identified as Patella miniata ), has revealed that their sperm are distinctly different, as well being different from that of P. miniata from South Africa. Subsequently, the species from Namibia was identified as P. adansonii . Furthermore, P. cf. miniata from S. Angola had a sperm which is remarkably similar to that of P. safiana from N.W. Africa and the two may be conspecific.

Full textAbstract:
A confirmed case of human brucellosis motivated an investigation into the potential source of infection in Namibia. Since domestic animals are principal sources of Brucella infection in humans, 1692 serum samples were screened from sheep, goats and cattle from 4 presumably at-risk farms and 900 springbok (Antidorcas marsupialis) serum samples from 29 mixed farming units for Brucella antibodies by the Rose-Bengal test (RBT) and positive cases confirmed by complement fixation test (CFT). To assess the prevalence of human brucellosis, 137 abattoir employees were tested for Brucella antibodies using the standard tube agglutination test (STAT) and by enzyme linked immunosorbent assay (ELISA). Cattle and sheep from all 4 farms were negative by RBT and CFT but 2 of the 4 farms (Ba and C) had 26/42 and 12/285 seropositive goats, respectively. Post mortem examination of seropositive goats revealed no gross pathological lesions typical of brucellosis except enlarged mesenteric and iliac lymph nodes seen in a single buck. Culture for brucellae from organs of seropositive animals was negative. None of the wildlife sera tested positive by either RBT or CFT. Interviews revealed that besides the case that prompted the investigation, a family and another person from other farms with confirmed brucellosis shared a common history of consumption of unpasteurised goat milk, home-made goat cheese and coffee with raw milk and prior contact with goats, suggesting goats as the likely source of infection. All 137 abattoir employees tested negative by STAT, but 3 were positive by ELISA. The 3 abattoir workers were clinically normal and lacked historical connections with clinical cases. Although goats are often associated with B. melitensis, these studies could not explicitly implicate this species owing to cross-reactivity with B. abortus, which can also infect goats. Nevertheless, these data reinforce the need for a better National Control Programme for brucellosis in Namibia.

Full textAbstract:
The African penguin (Spheniscus demersus) is an endangered seabird that breeds along the coast of Namibia and South Africa, and disease surveillance was identified as a priority for its conservation. Aiming for the establishment of baseline data on the presence of potential pathogens in this species, a comprehensive health assessment (blood smear examination, haematology, biochemistry and serology) was conducted on samples obtained from 578 African penguins at 11 breeding colonies and a rehabilitation centre. There were 68 penguins that were seropositive for at least one of seven pathogens tested: avian encephalomyelitis virus, avian infectious bronchitis virus, avian reovirus, infectious bursal disease virus, Newcastle disease virus, Mycoplasma gallisepticum and Mycoplasma synoviae. All samples were seronegative for avian influenza virus subtypes H5 and H7 and infectious laryngotracheitis virus. The apparent prevalence of Babesia sp. and Borrelia sp. in blood smears was consistent with previous studies. Babesia-infected individuals had a regenerative response of the erythrocytic lineage, an active inflammatory response and hepatic function impairment. These findings indicate that African penguins may be exposed to conservation-significant pathogens in the wild and encourage further studies aiming for the direct detection and/or isolation of these microorganisms.

Full textAbstract:
Post-event debriefing has been described as an effective tool in improving learning achievements in simulator-based teaching. This article examines the effect of structured post-event debriefing sessions in simulator-based veterinary clinical skills training. Nineteen Namibian veterinary students took part in instructor-led practice, self-directed practice with structured post-event debriefing and self-directed practice without debriefing (control) at three different learning stations in a veterinary clinical skills laboratory. Students evaluated their practice experience using Likert-type scales and learning achievements were assessed using an objective structured clinical examination (OSCE). The results show that the choice of practice model had no significant effect on learning achievements overall. However, at individual learning stations, different practice models showed significant differences regarding effect on learning achievements. Students generally preferred practice sessions with some form of instructor involvement but the importance of instructor guidance was rated differently at each individual learning station.
