Pulotu: Database of Austronesian Supernatural Beliefs and Practices

Scholars have debated naturalistic theories of religion for thousands of years, but only recently have scientists begun to test predictions empirically. Existing databases contain few variables on religion, and are subject to Galton’s Problem because they do not sufficiently account for the non-independence of cultures or systematically differentiate the traditional states of cultures from their contemporary states. Here we present Pulotu: the first quantitative cross-cultural database purpose-built to test evolutionary hypotheses of supernatural beliefs and practices. The Pulotu database documents the remarkable diversity of the Austronesian family of cultures, which originated in Taiwan, spread west to Madagascar and east to Easter Island–a region covering over half the world’s longitude. The focus of Austronesian beliefs range from localised ancestral spirits to powerful creator gods. A wide range of practices also exist, such as headhunting, elaborate tattooing, and the construction of impressive monuments. Pulotu is freely available, currently contains 116 cultures, and has 80 variables describing supernatural beliefs and practices, as well as social and physical environments. One major advantage of Pulotu is that it has separate sections on the traditional states of cultures, the post-contact history of cultures, and the contemporary states of cultures. A second major advantage is that cultures are linked to a language-based family tree, enabling the use phylogenetic methods, which can be used to address Galton’s Problem by accounting for common ancestry, to infer deep prehistory, and to model patterns of trait evolution over time. We illustrate the power of phylogenetic methods by performing an ancestral state reconstruction on the Pulotu variable “headhunting", finding evidence that headhunting was practiced in proto-Austronesian culture. Quantitative cross-cultural databases explicitly linking cultures to a phylogeny have the potential to revolutionise the field of comparative religious studies in the same way that genetic databases have revolutionised the field of evolutionary biology.     

Parent Civic Beliefs,Civic Participation,Socialization Practices,and Child Civic Engagement

We examined civic engagement in middle childhood and the degree to which parents’ civic beliefs (i.e., social trust and civic efficacy), civic participation, and socialization practices were associated with indicators of children's civic engagement (i.e., social responsibility and civic values). Survey data were collected from 359 racially, ethnically, and economically diverse upper elementary students and their parents from six schools in Southern California. The results of path analyses indicated that higher levels of parent social trust were associated with higher levels of community responsibility and civic values in children. Additionally, parent social trust, civic efficacy, and civic participation were indirectly associated with children's community responsibility and civic values through children's perception of their parents as civic role models. Findings suggest that parents’ civic beliefs and civic participation are meaningful to children's civic engagement.     

Health Beliefs and Practices Related to Dengue Fever: A Focus Group Study

Background

This qualitative study aimed to provide an in-depth understanding of the meaning of dengue fever (DF) amongst people living in a dengue endemic region, dengue prevention and treatment-seeking behaviours. The Health Belief Model was used as a framework to explore and understand dengue prevention behaviours.

Methods

A total of 14 focus group discussions were conducted with 84 Malaysian citizens of different socio-demographic backgrounds between 16^th December, 2011 and 12^th May, 2012.

Results

The study revealed that awareness about DF and prevention measures were high. The pathophysiology of dengue especially dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS) were rarely known; as a result, it was seen as deadly by some but was also perceived as easily curable by others without a basis of understanding. Young adults and elderly participants had a low perception of susceptibility to DF. In general, the low perceived susceptibility emerged as two themes, namely a perceived natural ability to withstand infection and a low risk of being in contact with the dengue virus vector, Aedes spp. mosquitoes. The barriers to sustained self-prevention against dengue prevention that emerged in focus groups were: i) lack of self-efficacy, ii) lack of perceived benefit, iii) low perceived susceptibility, and iv) unsure perceived susceptibility. Low perceived benefit of continued dengue prevention practices was a result of lack of concerted action against dengue in their neighborhood. Traditional medical practices and home remedies were widely perceived and experienced as efficacious in treating DF.

Conclusion

Behavioural change towards attaining sustainability in dengue preventive practices may be enhanced by fostering comprehensive knowledge of dengue and a change in health beliefs. Wide use of unconventional therapy for DF warrants the need to enlighten the public to limit their reliance on unproven alternative treatments.     

Some Implications of Medical Beliefs and Practices for Social Anthropology

A people's medical beliefs and practices persist because they answer instrumental and moral imperatives, and they are empirically effective. This is not the same thing as saying that they are effective from the standpoint of Western medical notions or that they always bring the results for which people hope. The empirical effectiveness of these practices has important ontological consequences, since it enables sickness episodes to communicate and confirm ideas about the real world.     

Traditional Health Beliefs and Practices Among Lower Class Black Americans

The medical belief system of lower class black Americans reflects their social, political and economic marginality in the larger society. A moderate life-style is regarded as the basis for good health with special emphasis on protecting one''s body from cold, keeping it clean inside and out and maintaining a proper diet. Illnesses and other life events are classified as “natural” or “unnatural.” Natural illnesses result from the effects of cold, dirt and improper diet on the body causing changes in the blood. A number of beliefs about blood and its functions have important clinical implications for the treatment of hypertension and venereal disease and for family planning. Natural illnesses also result from divine punishment and serve as an instrument of social control. Unnatural illnesses are the result of witchcraft and reflect conflict in the social network. It is believed that physicians do not understand and cannot effectively treat such illnesses, but a variety of traditional healers offer help to the victims. Physicians must elicit such beliefs if they are to interact effectively and sensitively with black patients. Social change is required, however, to eliminate the feelings of powerlessness at the root of many of the health problems of poor black Americans.     

Local Perceptions,Cultural Beliefs and Practices That Shape Umbilical Cord Care: A Qualitative Study in Southern Province,Zambia

Background

Global policy regarding optimal umbilical cord care to prevent neonatal illness is an active discussion among researchers and policy makers. In preparation for a large cluster-randomized control trial to measure the impact of 4% chlorhexidine as an umbilical wash versus dry cord care on neonatal mortality in Southern Province, Zambia, we performed a qualitative study to determine local perceptions of cord health and illness and the cultural belief system that shapes umbilical cord care knowledge, attitudes, and practices.

Methods and Findings

This study consisted of 36 focus group discussions with breastfeeding mothers, grandmothers, and traditional birth attendants, and 42 in-depth interviews with key community informants. Semi-structured field guides were used to lead discussions and interviews at urban and rural sites. A wide variation in knowledge, beliefs, and practices surrounding cord care was discovered. For home deliveries, cords were cut with non-sterile razor blades or local grass. Cord applications included drying agents (e.g., charcoal, baby powder, dust), lubricating agents (e.g., Vaseline, cooking oil, used motor oil) and agents intended for medicinal/protective purposes (e.g., breast milk, cow dung, chicken feces). Concerns regarding the length of time until cord detachment were universally expressed. Blood clots in the umbilical cord, bulongo-longo, were perceived to foreshadow neonatal illness. Management of bulongo-longo or infected umbilical cords included multiple traditional remedies and treatment at government health centers.

Conclusion

Umbilical cord care practices and beliefs were diverse. Dry cord care, as recommended by the World Health Organization at the time of the study, is not widely practiced in Southern Province, Zambia. A cultural health systems model that depicts all stakeholders is proposed as an approach for policy makers and program implementers to work synergistically with existing cultural beliefs and practices in order to maximize effectiveness of evidence-based interventions.     

Menstruation, perimenopause, and chaos theory

This article argues that menstruation, including the transition to menopause, results from a specific kind of complex system, namely, one that is nonlinear, dynamical, and chaotic. A complexity-based perspective changes how we think about and research menstruation-related health problems and positive health. Chaotic systems are deterministic but not predictable, characterized by sensitivity to initial conditions and strange attractors. Chaos theory provides a coherent framework that qualitatively accounts for puzzling results from perimenopause research. It directs attention to variability within and between women, adaptation, lifespan development, and the need for complex explanations of disease. Whether the menstrual cycle is chaotic can be empirically tested, and a summary of our research on 20- to 40-year-old women is provided.     

Community Knowledge,Health Beliefs,Practices and Experiences Related to Dengue Fever and Its Association with IgG Seropositivity

Background

Demographic, economic and behavioural factors are central features underpinning the successful management and biological control of dengue. This study aimed to examine these factors and their association with the seroprevalence of this disease.

Methodology

We conducted a cross-sectional telephone survey of households in a 3 km radius of the schools where we had conducted serological tests on the student population in a previous study. Households were surveyed about their socio-demographics, knowledge, practices, and Health Belief Model (HBM) constructs. The results were then associated with the prevalence rate of dengue in the community, as marked by IgG seropositivity of the students who attended school there.

Results

A total of 1,400 complete responses were obtained. The community''s IgG seropositivity was significantly positively associated with high household monthly income, high-rise residential building type, high surrounding vegetation density, rural locality, high perceived severity and susceptibility, perceived barriers to prevention, knowing that a neighbour has dengue, frequent fogging and a higher level of knowledge about dengue. In the multivariate analyses, three major correlates of the presence of IgG seropositivity in the community: (1) high-rise residential apartment house type or condominium buildings; (2) the main construct of the HBM, perceived severity and susceptibility; and (3) the additional constructs of the HBM, lack of preventive measures from the community level and having a neighbour with dengue as a cue to action. Weak correlations were found between self-practices to prevent dengue and the level of dengue seropositivity in the community, and between HBM constructs and knowledge (r = 0.09).

Conclusions

The residential environment factor and the constructs of the HBM are useful and important elements in developing interventions to prevent and control dengue. The study also sheds light on the importance of the need for approaches that ensure the translation of knowledge into practice.
