Population biology of Octopus vulgaris on the temperate south-eastern coast of South Africa

Population structure and biology of Octopus vulgaris was investigated along the south-eastern coast of South Africa. Samples were collected inter- and sub-tidally as a precursor to the establishment of an experimental octopus fishery in the region. In total, 300 (intertidal) and 147 (subtidal) O. vulgaris were collected over a two year period. Females were found to dominate the intertidal area (sex ratio 2:1), while no difference was found subtidally (sex ratio 1:1). Of those collected intertidally, immature females were most prevalent while males ranged from immature to mature. Mature females were only found subtidally. A marked size difference was apparent, with the subtidal octopus being substantially larger. Although brooding females were found throughout the year, numbers peaked in summer. Individual fecundity ranged between 42,000–790,000 eggs. The total number of eggs produced and the number of eggs per egg string were correlated to female size. Diet did not vary greatly between the inter- and sub-tidal areas, with the main prey items being crustaceans, teleosts and octopus. It appears that the immature females use the intertidal area to feed and grow, before migrating to deeper areas to mature and spawn

Are the rights of the disabled a reality in South Africa? Part two

For a long time the rights of disabled persons have been ignored not only in South Africa, but also in the rest of the world. There are many disabled persons who can participate on an equal level with able-bodied persons, but on the other hand there are many disabled persons who are unable to do so due to the nature and severity of their disabilities. Discrimination against disabled persons lead to the exclusion of them to function in a normal way in the community and the denial of their rights and to function freely in society. Legislation can assist in the prevention of discrimination against such persons and also in their upliftment

Dying to starve: A comparative analysis of legal aspects relating to consent in force-feeding of both minor and adult anorexic patients

The authors explore the legal complexities surrounding the force-feeding of anorexic patients. Due to the myriad of difficulties relating to anorexia nervosa, treatment is intricate. The aim of this exposition is to clarify legal issues of consent and self-determination, with regard to both adult and minor patients. In addition, the distinction between ‘irrational’ and ‘incompetent’ refusal will be discussed, with the authors maintaining that the ‘irrational’ refusal of an adult patient should be respected by the law. To come to an informed conclusion, the authors will first analyse the medical and psychological aspects of anorexia nervosa. Secondly, the South African position as shaped by the Mental Health Care Act, the Children’s Act and the National Health Act will be contrasted with the position in Great Britain in order to determine the international perspective and its contrast, or not, to South African law

Concepts of creative leadership of women leaders in 21st century

Abstract: This article presents the subjective perspectives of women leaders working in higher education institutions in the 21st century in South Africa. It focuses in particular on creativity as demonstrated by women leaders working in culturally and gender diverse post-apartheid settings. The aim is to contribute to the discourse on the creativity of women leaders from diverse cultural backgrounds within South Africa higher education institutions by examining how women leaders experience creativity and what creativity means to them from a qualitative perspective. The study reported on assessed the experiences of creativity of 23 women leaders and their views on creativity and creative leadership by means of a research paradigm based on Wilhelm Dilthey’s modern hermeneutics. It used qualitative research methods, such as semi-structured interviews, as well as observations within one selected higher education institution. Data was analysed by means of content analysis. Quality research criteria and ethical considerations were upheld. The findings highlight the creative skills and attitudes of women leaders underlying successful leadership and the types of creative leadership applied. They suggest that women leaders’ creativity manifests in facilitating creativity in higher education institutions by fostering the creativity of others rather than directing their own creative vision through or integrating it in the work of employees

Effective leadership considering emotional intelligence in a leadership environment.

The primary objective is to establish whether a potential trend exists between effective leadership and emotional intelligence (EI). This research also investigates whether possible trends exist between leadership and emotional intelligence in terms of the leadership styles: transformational or transactional leadership. Insight is also gained into whether male or female student leaders practice either transformation or transactional leadership styles. The sample was identified as the student leaders at the University of Johannesburg's Auckland Park Kingsway campus. The sample ultimately included 123 respondents for all the committees in the institution, resulting in a very positive response rate for data analysis. The findings revealed that there was insufficient evidence to support the objective that specific trends exist between leadership effectiveness when considering emotional intelligence or whether emotional intelligences relates more strongly with a transformational or transactional leadership style. However relevant relationships between female respondents and the transformational leadership style could be established

Post traumatic stress disorder: undiagnosed cases in a tertiary inpatient setting

Objective: Post traumatic stress disorder (PTSD) is a common, debilitating anxiety disorder characterized by emotional and physical symptoms that may occur after exposure to a severely traumatic event. Since it occurs commonly as a comorbid diagnosis with other mood- and anxiety disorders, we postulated that this disorder may be under- diagnosed in therapeutic wards where anxiety and mood disorders are treated. The study thus sought to determine the prevalence of undiagnosed PTSD in an inpatient population, and to compare the demographic details and comorbid diagnoses of subjects with and without PTSD. Method: The Clinician-administered PTSD Scale for DSM-IV (CAPS) was administered to 40 subjects who were inpatients in a therapeutic ward of a large psychiatric hospital and who had never had a diagnosis of PTSD before. Results:16 (40%) subjects met the DSM-IV criteria for PTSD. We did not find significant clinical differentiating factors between subjects with and without PTSD; however subjects with PTSD were more likely to use cannabis. Conclusions: PTSD remains undiagnosed in many patients admitted to therapeutic units.

Quantitative and qualitative analysis of sterols/sterolins and hypoxoside contents of three Hypoxis (African potato) spp.

The glycoside, hypoxoside, identified and isolated from the corms of the African potato (Hypoxis hemerocallidea) has shown promising anticancer activities. The African potato is used as an Africantraditional medicine for its nutritional and medicinal properties. Most research has been carried out on H. hemerocallidea (formerly known as H. rooperi), with very little or nothing on other Hypoxis spp. Thinlayer chromatography (TLC) was used to confirm the presence of sterols/sterolins, whereas a GC method was developed to identify and quantify sterols (especially β-sitosterol) in chloroform extracts of H. hemerocallidea, H. stellipilis and H. sobolifera var. sobolifera. High performance liquid chromatography (HPLC) was used to identify and quantify hypoxoside content in these Hypoxis spp. TLC results showed that H. sobolifera var. sobolifera contained the most sterols and sterolins compared to the other two Hypoxis spp. Gas chromatography (GC) results show that β-sitosterol and campesterol were the two main phytosterols present in the Hypoxis extracts. H. sobolifera var. sobolifera and H. hemerocallidea contained the most β-sitosterol and hypoxoside, respectively. H. sobolifera and H. hemerocallidea contained 74.69 µg of β-sitosterol and 12.27 µg of hypoxoside per 5 mg of chloroform extracts, respectively. These results show a significant difference in the sterol/sterolin and hypoxoside contents between species of the genus Hypoxis, which may influence their degree of biological activities

Job and family stress amongst firefighters

Firefighters providing emergency services to the public are involved with some of the most tragic aspects of the boundary between life and death, often in a context over which they have little or no control. The outcome of this may be that stress at work and at home are without doubt the reason that highly qualified and loyal firefighters give themselves over to alcohol or drug abuse, extramarital relationships and suicidal thoughts. The general aim of the research is to evaluate job and family stress amongst firefighters in the South African context, and to use the results in developing a developmental/counselling programme for firefighters and their families. The research is quantitative and qualitative, consisting of a survey design and a phenomenological design. Three measuring instruments were used, namely the Biographical questionnaire, the Experience of Work and Life Circumstances questionnaire, and the Stress questionnaire. Task characteristics, organisational functioning, physical working conditions and job equipment, career and social matters, remuneration, fringe benefits and personnel policy were identified as causes of job stress originating within the work situation. Interviews were conducted to determine how these firefighters experience job and family stress. Marital dysfunction and divorce, limited time with the family, problems with children, alcohol and drug abuse, lack of exercise, suicide, anger aimed at family members, physical and emotional exhaustion, lonely marital partners, unavailability to help the family when needed and depression were identified as causes of family stress arising outside the work situation. The main recommendation is to implement a developmental/counselling job and family stress programme. The programme can be instituted to enhance the wellness and psychological health of firefighters and their families, or for counselling of firefighters and their families who are experiencing job and/or family stress. The multi-dimensionality and flexibility make this programme unique and one of its kind in the South African context.Indust and Org PsychologyDLITT ET PHIL (IND & ORG PS
