Exploring the heuristic value of nonpersonal data for sexual- and genderbased violence research and prevention in South Africa

Research and media reports indicate that most incidents of sexual and gender-based violence (SGBV) in South Africa, as well as globally, are not reported to the police because of victims’ fears of retaliation, intimidation, stereotyping, secondary abuse and stigmatisation. As a result, there is a lack of accurate data available to the South African public and a certain level of ignorance to the realities of the incidence of SGBV across all sectors of society. The purpose of the study is to explore how non-personal data obtained through mapping the distress calls received on TEARS Foundation’s “Help-at-your-fingertips” service line can be used for SGBV research and prevention purposes. Given that in South Africa the death of women at the hands of an intimate partner has been estimated at six times the global average, the urgent need for alternative SGBV prevention strategies is unquestionable. The study shows how the calls received on the “Help-atyour- fingertips” service line across South African provinces and towns were analysed to identify trends, and visually represent the number of SGBV distress calls over two periods, namely July 2013 to August 2014 and September 2015 to October 2016. The key trends identified include times of year, times of day, highest call volumes in terms of provinces and differences in times of calls in different areas in South Africa as examples of the kinds of information that can be deduced from non-personal data.The study shows how non-personal data can be used as a powerful tool to make SGBV data visible and to raise public awareness of its incidence in South Africa.Keywords: Sexual and gender-based violence (SGBV), geographic mapping, crimemapping, communication, SGBV prevention, TEARS Foundation, “Help-at-your-fingertips

A second-order cybernetic explanation for the existence of network direct selling organisations as self-creating systems

Network Direct Selling Organisations (NDSOs) exist in more than 50 countries and have more than 74 million members. The most recent statistical information reveals that the vast majority of members do not earn significant income. Criticism of these organisations revolves around the ethicality of consumption, the commercialisation of personal relationships, and the exploitation of unrealistic expectations. This study aims to explore how communication creates networks that sustain an industry of this kind despite the improbability of its existence. The study commences with a description of NDSOs from historical, operational, tactical, and strategic perspectives. Given the broader context created by the global presence of this industry, cybernetics has been selected as a meta-theoretical perspective for the study of communication. The more recent development of second-order cybernetics and social autopoiesis are introduced to communication theory as a field. Niklas Luhmann‟s new social theory of communication is assessed and applied in relation to existing communication theory. New conceptual models are developed to explore communication as the unity of the synthesis of information, utterance, understanding, and expectations as selections that occur both consciously and unconsciously, intentionally and unintentionally. These models indicate the multiplexity of individual and social operationally closed, yet informationally open systems, and they are used here to provide a systemic and coherent alternative to orthodox communication approaches to the study of organisations. The study adopts a constructivist epistemological stance and propounds throughout the necessity of further interdisciplinary collaboration. The study concludes that individuals are composite unities of self-creating systems, and they co-create social systems by self-creating and co-creating meaning. Meaning is described as the continuous virtualisation and actualisation of potentialities that in turn coordinate individual and social systems‟ actions. A communication process flow model is created to provide a theoretical explanation for the existence of NDSOs as self-creating systems. The study aims to show that communication has arguably become the most pervasive discipline as a result of the globally interactive era. It is shown that second-order cybernetics and social autopoiesis raise several further questions to be explored within communication theory as a field.Communication, first-order cybernetics, second-order cybernetics, Complexity and complex systems, autopoiesis, self-reference, recursivity, operational closure, system boundaries, Network Direct Selling OrganisationsCommunicationD.

Knowledge, perceptions, beliefs, and opinions of the employees about GBV: a national online study in South Africa

Abstract Background GBV has been global public health, family, and social problem for several decades as it is expensive for society and the economy. The study was conducted to determine the possible differences in knowledge, perceptions, beliefs, and opinions about GBV, as a whole, across gender and employment sectors in South Africa. Methods This was a cross-sectional study using mixed-method design where we used an online survey with two open-ended questions. Perception about GBV Prevention among Employees (GBVPREV) questionnaire consisting of six Sect. (43 questions) was developed and tested. Cronbach’s alpha, Exploratory factor analysis (EFA), including Kaiser-Meyer Olkin Measure of Sampling Adequacy (KMO) and Bartlett’s test of Sphericity, one-way analysis of variance (ANOVA) and Tukey HSD were used. Content analysis was used for analysing qualitative information from two open-ended questions. Results Among the 2 270 employees, more than half (68.1%) were females. Males were 677 (29.8%), and members of the LGBTQIAP + community were 32 (1.4%). There were statistically significant differences among males, females, and LGBTQIAP + on employee knowledge of adult experiences, employee knowledge of violence against children, employee perceptions, employee beliefs, and employee opinions and recommendations. The employees believe that all sectors of society should collaborate in addressing GBV in South Africa. They felt that victims should be encouraged to come forward, that society should be less judgemental, that stigma should be addressed and that there should be more empathy for victims. Conclusion Most of the respondents, who were female and had tertiary education, were employed in the private sector, and were very aware of the prevalence of GBV in South Africa, agreed that support for both victims and perpetrators must be provided in private sector organizations. Even though it has been acknowledged for decades that gender inequality and GBV are reciprocal drivers, the persistence of both human rights violations will continue if all stakeholders do not collaborate

An Indirect Genetic Algorithm for a Nurse Scheduling Problem

This paper describes a Genetic Algorithms approach to a manpower-scheduling problem arising at a major UK hospital. Although Genetic Algorithms have been successfully used for similar problems in the past, they always had to overcome the limitations of the classical Genetic Algorithms paradigm in handling the conflict between objectives and constraints. The approach taken here is to use an indirect coding based on permutations of the nurses, and a heuristic decoder that builds schedules from these permutations. Computational experiments based on 52 weeks of live data are used to evaluate three different decoders with varying levels of intelligence, and four well-known crossover operators. Results are further enhanced by introducing a hybrid crossover operator and by making use of simple bounds to reduce the size of the solution space. The results reveal that the proposed algorithm is able to find high quality solutions and is both faster and more flexible than a recently published Tabu Search approach

The effect of intravenous administration of a chimeric anti-IgE antibody on serum IgE levels in atopic subjects: efficacy, safety, and pharmacokinetics.

CGP 51901 is a non-anaphylactogenic mouse/human chimeric anti-human IgE antibody that binds to free IgE and surface IgE of IgE-expressing B cells but not to IgE bound to high affinity IgE receptors (Fc epsilonR1) on mast cells and basophils or low affinity IgE receptors (Fc epsilonR2) on other cells. A phase 1 double-blind, placebo-controlled, single dose study with doses of 3, 10, 30, and 100 mg of CGP 51901 was conducted in 33 pollen-sensitive subjects who had raised levels of serum IgE and received either intravenous CGP 51901 or placebo. The administration of CGP 51901 was well tolerated and resulted in a decrease of serum free IgE levels in a dose-dependent manner, with suppression after 100 mg of CGP 51901 reaching > 96%. Time of recovery to 50% of baseline IgE correlated with the dose of administered antibody and ranged from a mean of 1.3 d for the 3 mg to 39 d for the 100 mg dose. Total IgE, comprised of free and complexed IgE, increased as stored and newly synthesized IgE bound to CGP 51901. Complexed IgE was eliminated at a rate comparable with the terminal half-life of free CGP 51901 (11-13 d at all doses). Only one subject showed a weak antibody response against CGP 51901. We conclude that the use of anti-human IgE antibody is safe and effective in reducing serum IgE levels in atopic individuals and provides a potential therapeutic approach to the treatment of atopic diseases
