A Phenomenological Study on Entrepreneurial Identity of Female Entrepreneurs in South Africa
Objective: To understand the entrepreneurial identity, through the lived experience of female entrepreneurs who are familiar with the phenomenon. This objective was premised on understanding that entrepreneurial identity is a product of context which shapes the social-cultural norms and environment within which individuals, operate and construct their identity. This is captured in entrepreneurship scholarship where the discipline is still struggling to build a reliable definition of female entrepreneurship applicable to both developed and developing countries and its effect on their respective economies. Research Design & Methods: This study used a qualitative research design that followed a phenomenological approach with thirty five female entrepreneurs, utilising semi structured in depth individual meetings. Findings: Female entrepreneurs build, balance, and manage a wide range of entrepreneurial ventures of varying sizes across sectors while maintain both role and social identities. Female entrepreneurs also express strong views on earning returns and income to not only grow their business but support their employees, communities, themselves, and their families. Implications & Recommendations: This study generated five themes that should be researched quantitatively to determine further understanding of entrepreneurship and developing other entrepreneurs in developing countries. Contribution & Value Added: The study contributes to the existing body of knowledge on entrepreneurship in entrepreneurial identity, by exploring the female entrepreneur as both a role and identity. It examines this through the perspective of role identity and learn how female entrepreneurs consider their role as an entrepreneur
Influence of strategic management practices on the entrepreneurial orientation of South African firms in the financial and business services sector
In this dissertation, strategic management and corporate entrepreneurship are
combined in a single empirical research investigating the influence of business
strategic management practices on organisational entrepreneurial orientation.
Understanding this relationship has progressively become crucial in todayâs
hypercompetitive global environment where businesses, regardless of national
location, size, age and industry, are facing incessant and dynamic change.
Specifically, the influence of strategic management practices on corporate
entrepreneurship in medium to large corporations in the financial and business
services sector in South Africa is analysed by testing hypotheses that predict the
relationship between strategic management dimensions of locus of planning,
scanning intensity, planning flexibility, planning horizon, and strategy control
attributes, and entrepreneurial orientation. By applying factor, cluster and multiple
regression statistical analyses, the study made four key findings. First, the results
confirm that selected dimensions of strategic management practices influence the
entrepreneurial orientation of firms. This in turn effect the position a firm occupies
along a conceptual conservative-entrepreneurial continuum. Second, the study
indicates that firms with perceived higher entrepreneurial orientation exhibit better
performance measures. This finding supports the thesis that entrepreneurial
orientation is an integral component for business performance in attaining
sustainable competitive advantage, achieving above-average earnings and wealth
creation. Third, a methodology that combined strategic management and corporate
entrepreneurship in a single research generated new knowledge confirming that
entrepreneurial orientation is a key construct in both subdisciplines. Fourth, the
results show that divergent organisational entrepreneurial orientation profiles help in
classifying firms along the entrepreneurial continuum. Furthermore, the research
made a provisional finding that there are four possible distinct and excusive clusters
of business groups along the conservative-entrepreneurial continuum in determining
corporate entrepreneurial orientation in organisation
Sacred powers and rituals of transformation: An ethnoarchaeological study of rainmaking rutuals and agricultural productivity during The evolution of The Mapungubwe State,AD 1000 to AD 1300

Faculty of HumanitiesThe study of sacred leadership at Mapungubwe involves an analysis of
how the emerging elite centralised rainmaking and other public rituals.
These developments occurred in the Shashe-Limpopo basin between AD
1000 and AD 1300. Mapungubwe was the last in a sequence of capitals in
the basin. The first was Schroda (AD 900-1000), followed by K2 (AD 1000-
1220) and then Mapungubwe (AD 1220-1300). This sequence
corresponds to a series of cultural, socio-political and economic
transformations that led to class distinction and sacred leadership, two
distinctive features of the regionâs early state system.
The development of Mapungubwe was a local indigenous accomplishment
that occurred in the prehistoric period but in the relatively recent past. This
offers possibilities for using current indigenous knowledge to develop
relevant ethnographic models.
Over a period of four years, I explored Venda, Sotho-Tswana and Shona
traditional agriculture strategies and belief systems through their oral
histories, cosmologies and practices. I identified three systems of
rainmaking practices. Practice A is associated with kin-based chiefdoms.
Practise B exists among class-based polities with sacred leadership.
Practice C represents the devolution of complexity after the disintegration
of the Zimbabwe culture. These data provide models to clarify the roles of
rainmaking and agriculture in the evolution of Mapungubwe
Alkali production in the mouth and its relationship with certain patient's characteristics
Objectives To assess the relationships among alkali production, diet, oral health behaviors, and oral hygiene. Methods Data from 52 subjects including demographics, diet, and oral hygiene scores were analyzed against the level of arginine and urea enzymes in plaque and saliva samples. An oral habit survey was completed that included: use of tobacco (TB), alcohol (AH), sugary drinks (SD), and diet. Alkali production through arginine deiminase (ADS) and urease activities were measured in smooth-surface supragingival dental plaque and un stimulated saliva samples from all subjects. ADS and urease activities were measured by quantification of the ammonia generated from the incubation of plaque or saliva samples. Spearman correlations were used to compute all associations. Results Participants in the lowest SES (Socio-economic status) group had the habit of consuming sugary drinks the most and had the highest rate of tobacco use. Males consumed significantly more alcohol than females. No significant relationship was found between age or gender and alkali production. Higher rates of sugary drink consumption and tobacco use were significantly related to lower alkali production. Conclusion The study showed a relationship between alkali production and oral hygiene, diet, and certain oral health behaviors. Poor oral hygiene was significantly associated with age, lower SES, tobacco use, and alcohol, and sugary drinks consumption. Clinical relevance Certain oral health behaviors have an impact on oral hygiene and on alkali production; it is important to address these factors with patients as a strategy for caries control
Echinoderms have bilateral tendencies
Echinoderms take many forms of symmetry. Pentameral symmetry is the major
form and the other forms are derived from it. However, the ancestors of
echinoderms, which originated from Cambrian period, were believed to be
bilaterians. Echinoderm larvae are bilateral during their early development.
During embryonic development of starfish and sea urchins, the position and the
developmental sequence of each arm are fixed, implying an auxological
anterior/posterior axis. Starfish also possess the Hox gene cluster, which
controls symmetrical development. Overall, echinoderms are thought to have a
bilateral developmental mechanism and process. In this article, we focused on
adult starfish behaviors to corroborate its bilateral tendency. We weighed
their central disk and each arm to measure the position of the center of
gravity. We then studied their turning-over behavior, crawling behavior and
fleeing behavior statistically to obtain the center of frequency of each
behavior. By joining the center of gravity and each center of frequency, we
obtained three behavioral symmetric planes. These behavioral bilateral
tendencies might be related to the A/P axis during the embryonic development of
the starfish. It is very likely that the adult starfish is, to some extent,
bilaterian because it displays some bilateral propensity and has a definite
behavioral symmetric plane. The remainder of bilateral symmetry may have
benefited echinoderms during their evolution from the Cambrian period to the
present
Culturing Echinoderm Larvae Through Metamorphosis
Echinoderms are favored study organisms not only in cell and developmental biology, but also physiology, larval biology, benthic ecology, population biology and paleontology, among other fields. However, many echinoderm embryology labs are not well-equipped to continue to rear the post-embryonic stages that result. This is unfortunate, as such labs are thus unable to address many intriguing biological phenomena, related to their own cell and developmental biology studies, that emerge during larval and juvenile stages. To facilitate broader studies of post-embryonic echinoderms, we provide here our collective experience rearing these organisms, with suggestions to try and pitfalls to avoid. Furthermore, we present information on rearing larvae from small laboratory to large aquaculture scales. Finally, we review taxon-specific approaches to larval rearing through metamorphosis in each of the four most commonly-studied echinoderm classesâasteroids, echinoids, holothuroids and ophiuroids.https://scholarworks.wm.edu/asbookchapters/1091/thumbnail.jp

acting as âstepping-stonesâ for dispersal, regional centers of genetic isolation and speciation, and
refugia for deep-sea populations. This study focused on the patterns of dispersal and genetic
connectivity of four seamount ophiuroid species (Asteroschema clavigera, Ophiocreas oedipus,
Ophioplinthaca abyssalis and Ophioplinthaca chelys) displaying differing levels of associative
(epifaunal) specificity to cold-water coral hosts inhabiting the New England and Corner Rise
Seamount chains, and Muir Seamount in the Northwestern Atlantic. Analyses of mt16S and
mtCOI revealed evidence for recent population expansion and high gene flow for all four
species. However, species-specific genetic differentiation was significant based on seamount
region and depth. Significant differences were found among regional seamount groups for A.
clavigera, within seamount regions and seamounts for O. chelys, among 250 m depth intervals
for A. clavigera, among 100 m depth intervals for O. oedipus, and there were indications of
isolation by distance for A. clavigera and O. oedipus. In addition, A. clavigera and O. oedipus,
broadcast spawners with high fidelity to specific coral hosts, displayed predominantly westward
historical migration, while the ophioplinthacids, with lower host-specificity, displayed
predominantly eastward migration. No congruent patterns of historical migration were evident
among species and seamounts, yet these patterns can be correlated with species-specific host
specificity, specific depth strata, and dispersal strategies. Conservation efforts to protect
seamount ecosystems should promote multi-species approaches to genetic connectivity, and
consider the impact of the âdependenceâ of biodiversity on host fauna in these vulnerable marine
ecosystems.We are grateful for the support provided by the Office of Ocean Exploration, National Oceanic
