Personality traits,money attitudes and consumer decision-making styles as predictors of investment products choice in South Africa

This study examines how personality traits and money attitudes influence consumers' decision-making styles when purchasing investment products in South Africa. A sample of 269 South Africans completed the research questionnaire, which assessed their extraversion, conscientiousness, openness, money power/prestige, money retention/time, money quality, info-mising, extending, and tax-free investment purchase decision. Also, confirmatory factor analysis and structural equation modelling approaches were used to analyze the survey data. The results suggest that personality traits and money attitudes significantly impact consumer decision-making regarding tax-free investment products. However, the relationships between extraversion and money power/prestige and between info-mising decision styles and tax-tree investment purchase decisions were found to be negative. Cluster analysis revealed three distinct segments based on the characteristics of respondents and their drive for investment: strong conscientiousness investors, status-driven investors, and introverted investors. Marketing professionals and investment firms can use the study findings on consumer traits and money attitudes to improve marketing effectiveness in an organisation. Practically, extensive information processing has a fundamental bearing on investment decision-making in emerging markets. Extraversion and conscientiousness personality traits and money attitudes must be taken into consideration by investment products marketers and practitioners in marketing practice.     

Invisible “Others”: Sexual Health Vulnerabilities of Wives of Men who Have Sex with Men

The recent trend in the feminization of the HIV epidemic poses great risk to women, especially to the wives of men who have sex with men (MSM). The objective of the present study was to explore wives’ responses to their husbands’ sexual orientation as well as the factors that influence their sexual health in India. For this research, 15 wives who were aware of their husbands’ sexual orientation and their husbands were interviewed separately using semi-structured in-depth interviews and focus groups. The study explored the social and cultural structures that create gender inequality, which put women married to MSM at sexual health risk. These factors need to be addressed carefully through existing MSM targeted interventions, without breaching the confidentiality of either partner.     

On the archetypes in information systems development: An exploration

In this paper I examine possible archetypes that embody the role that systems analyst play in different models of systems development and briefly review attendant epistemological and ontological assumptions.     

On the Validity of Simulating Stagewise Development by Means of PDP Networks: Application of Catastrophe Analysis and an Experimental Test of Rule-Like Network Performance

This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget's theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motivated from catastrophe theory, a mathematical theory of transitions in epigenetical systems, no evidence for stage transitions in network performance was found. It is concluded that PDP networks lack the ability to recover the positive outcomes of analogous catastrophe analyses of real cognitive developmental data. In an attempt to further characterize the learning behaviour of PDP networks, we carried out a second simulation study using the discrimination-shift paradigm. The results thus obtained indicate that PDP learning is compatible with the learning of stimulus-response relationships, not with the acquisition of mediating rules such as conceived in (neo-)Piagetian theory. In closing, we speculate about the feasibility of simulating stagewise development with alternative network architectures.     

Risk Management Principles for Nanotechnology

Risk management of nanotechnology is challenged by the enormous uncertainties about the risks, benefits, properties, and future direction of nanotechnology applications. Because of these uncertainties, traditional risk management principles such as acceptable risk, cost–benefit analysis, and feasibility are unworkable, as is the newest risk management principle, the precautionary principle. Yet, simply waiting for these uncertainties to be resolved before undertaking risk management efforts would not be prudent, in part because of the growing public concerns about nanotechnology driven by risk perception heuristics such as affect and availability. A more reflexive, incremental, and cooperative risk management approach is required, which not only will help manage emerging risks from nanotechnology applications, but will also create a new risk management model for managing future emerging technologies.     

Face processing in humans and new world monkeys: the influence of experiential and ecological factors

This study tests whether the face-processing system of humans and a nonhuman primate species share characteristics that would allow for early and quick processing of socially salient stimuli: a sensitivity toward conspecific faces, a sensitivity toward highly practiced face stimuli, and an ability to generalize changes in the face that do not suggest a new identity, such as a face differently oriented. The look rates by adult tamarins and humans toward conspecific and other primate faces were examined to determine if these characteristics are shared. A visual paired comparison (VPC) task presented subjects with either a human face, chimpanzee face, tamarin face, or an object as a sample, and then a pair containing the previous stimulus and a novel stimulus was presented. The stimuli were either presented all in an upright orientation, or all in an inverted orientation. The novel stimulus in the pair was either an orientation change of the same face/object or a new example of the same type of face/object, and the stimuli were shown either in an upright orientation or in an inverted orientation. Preference to novelty scores revealed that humans attended most to novel individual human faces, and this effect decreased significantly if the stimuli were inverted. Tamarins showed preferential looking toward novel orientations of previously seen tamarin faces in the upright orientation, but not in an inverted orientation. Similarly, their preference to look longer at novel tamarin and human faces within the pair was reduced significantly with inverted stimuli. The results confirmed prior findings in humans that novel human faces generate more attention in the upright than in the inverted orientation. The monkeys also attended more to faces of conspecifics, but showed an inversion effect to orientation change in tamarin faces and to identity changes in tamarin and human faces. The results indicate configural processing restricted to particular kinds of primate faces by a New World monkey species, with configural processing influenced by life experience (human faces and tamarin faces) and specialized to process orientation changes specific to conspecific faces.     

Dual-task processing in younger and older adults: similarities and differences revealed by fMRI

fMRI was used to explore age differences in the neural substrate of dual-task processing. Brain activations when there was a 100 ms SOA between tasks, and task overlap was high, were contrasted with activations when there was a 1000 ms SOA, and first task processing was largely complete before the second task began. Younger adults (M=21 yrs) showed activation in dorsolateral prefrontal cortex and in parietal areas as well as in ventral medial frontal cortex and sub-lobar areas. Activations in older adults (M=71 yrs) did not differ significantly from younger adults except for higher activations in occipital and polar prefrontal cortex. The results were well fit by a model with two networks managing dual-task interference, a medial prefrontal network that detects changes in the stimulus situation and maps them to associated changes in the valence of response mappings and a lateral frontal-parietal network that initiates and carries out the shift from one task to the other. The additional activations in older adults as a group and the correlations of individual differences in activation with performance were consistent with recruitment within each of these networks. Alternative explanations such as hemispheric asymmetry reduction and reactive rather than proactive processing in older adults were not supported.     

Perceptions of High-Risk Care and Barriers to Care Among Women at Risk for Hereditary Breast and Ovarian Cancer following Genetic Counseling in the Community Setting

Data are limited regarding barriers to care among women, with or at risk for hereditary breast and ovarian cancer (HBOC), following genetic counseling in the community setting. Using a telephone survey, we retrospectively addressed perceptions of post-genetic counseling medical care and barriers to care among 69 at-risk women from the non-academic setting. Of these, all agreed that following cancer screening recommendations was better than not following them; none felt recommendations were too difficult to follow; all believed screening would help keep them healthy; 57% believed screening would prevent cancer. Twenty-five percent noted discomfort with breast imaging; 29% found ovarian cancer screening uncomfortable. Close to a quarter of participants reported difficulty deciding whether or not to undergo risk-reducing mastectomy while 10% noted difficulty deciding for or against bilateral salpingo-oophorectomy. There were no perceived major barriers to care, although 38% felt that screening reminders would be helpful, and 10% needed more help in following through with care. Overall, participants believed that they were benefiting from their post-genetic counseling medical care. This work identified HBOC-related support needs to include: informational resources that promote improved understanding of cancer risk and high-risk management; screening reminder systems; and decision support tools.
