    This paper describes the primacy of trust in the social networks and livelihoods of rural Tanzanian women engaged in agro-entrepreneurial activity. The importance of trust emerged from a study of the “who you know” social and economic network knowledge systems of these enterprising women in Moshi, Tanzania and the role cell phones play within their networks. The nature of the women’s agricultural businessesand their perceptions of the characteristics of women business leaders and cooperative group members were also studied. The objective of the study was to identify opportunities for developing innovative cellphone-based applications that link smallscale farmers and other entrepreneurs to markets, thus enabling these entrepreneurs to utilize, strengthen and expand their social and economic networks. A complementary goal was to identify the characteristics of women who are likely to successfully champion new entrepreneurial ventures. Three data collection techniques were employed: (1) a Personal Digital Assistant (PDA) survey, (2) structured interviews; and (3) focus group interviews. There were 26 women participants in this network study - all living in multi-ethnic areas in, or near, the town of Moshi. Each participant was the proprietor of a stall selling agricultural products in one of the three town markets. A total of 92 relationships were described by these 26 women. The majority of the women primarily used cell phones in their business communication andconsidered cell phones crucial to their businesses. The women valued long-term relationships with over 70% of the business relationships described by the women having lasted for more than one year. The study revealed that these relationships were based very strongly on trust and respect. This primacy of trust in these networks was further validated by the individual interviews and focus group discussions. Loyalty and the maintenance of inter-personal relationships are more important than price in these women’s business-related decision-making. The findings suggest the importance of building trust while expanding “who you know” networks to create social and economic capital in rural African communities. The pervasiveness and importance of cell phones in these communities raises the possibility of employing this technology to create value by harnessing social capital and expanding social networks. An entrepreneurial venture called WishVast emerged from this study and is described in this paper. WishVast is a cellphone-based system that allows individuals to interact within an expanded, geographically dispersed social network – and as aresult, it enables traditionally isolated individuals to connect, communicate and coordinate with a large number of potential clients

    Uptake and Conversion of Radioactive Carbon Dioxide and Glucose in the Acerola and their Relationship to Ascorbic Acid Biosynthesis

    A study of the fate of radiocarbon-labeled glucose and carbon dioxide in the acerola (West Indian Cherry) has shown that these substances follow patterns of conversion comparable to those observed in other plants. These substances were not preferentially incorporated into ascorbic acid by acerola fruit. Sucrose, several amino acids, and malic acid appear to compete successfully with ascorbic acid for the label from these precursors

    <p>Abstract</p> <p>Background</p> <p>Although back pain is considered one of the most frequent reasons why patients seek complementary and alternative medical (CAM) therapies little is known on the extent patients are actually using CAM for back pain.</p> <p>Methods</p> <p>This is a post hoc analysis of a longitudinal prospective cohort study embedded in a RCT. General practitioners (GPs) recruited consecutively adult patients presenting with LBP. Data on physical function, on subjective mood, and on utilization of health services was collected at the first consultation and at follow-up telephone interviews for a period of twelve months</p> <p>Results</p> <p>A total of 691 (51%) respectively 928 (69%) out of 1,342 patients received one form of CAM depending on the definition. Local heat, massage, and spinal manipulation were the forms of CAM most commonly offered. Using CAM was associated with specialist care, chronic LBP and treatment in a rehabilitation facility. Receiving spinal manipulation, acupuncture or TENS was associated with consulting a GP providing these services. Apart from chronicity disease related factors like functional capacity or pain only showed weak or no association with receiving CAM.</p> <p>Conclusion</p> <p>The frequent use of CAM for LBP demonstrates that CAM is popular in patients and doctors alike. The observed association with a treatment in a rehabilitation facility or with specialist consultations rather reflects professional preferences of the physicians than a clear medical indication. The observed dependence on providers and provider related services, as well as a significant proportion receiving CAM that did not meet the so far established selection criteria suggests some arbitrary use of CAM.</p

    Teaching: Natural or Cultural?

    Get PDF
    In this chapter I argue that teaching, as we now understand the term, is historically and cross-culturally very rare. It appears to be unnecessary to transmit culture or to socialize children. Children are, on the other hand, primed by evolution to be avid observers, imitators, players and helpers—roles that reveal the profoundly autonomous and self-directed nature of culture acquisition (Lancy in press a). And yet, teaching is ubiquitous throughout the modern world—at least among the middle to upper class segment of the population. This ubiquity has led numerous scholars to argue for the universality and uniqueness of teaching as a characteristically human behavior. The theme of this chapter is that this proposition is unsustainable. Teaching is largely a result of recent cultural changes and the emergence of modern economies, not evolution

    Trust, Cell Phones, Social Networks And Agricultural Entrepreneurship In East Africa: A Dynamic Interdependence

    No full text
    African entrepreneurs operate within homogenous, tightly knit social networks of trusted individuals. &apos;Who you know&apos; networks can provide these entrepreneurs with significant advantages in social, economic or political situations. However, the challenge of expanding beyond such networks to access new knowledge, skills and resources can be met only by establishing relationships with individuals outside their existing sphere of trust. The widespread adoption of cell phones has radically impacted the social connectedness of agro-entrepreneurs in Africa and deeply affected their social networks and livelihoods. Cell phones help to easily maintain long distance business connections as well as social ties and decrease dependency on local, face-to-face interactions. New weak social ties may be economically beneficial because they can provide access to new resources and create larger networks. The mobile phone enables and accelerates these social network transformations and helps entrepreneurs aggregate and leverage social capital. A symbiotic relationship exists between social and economic capital. Social capital is generated through the existence of trust which, in turn, encourages cooperation in the generation of economic capital. The existence of trust can promote the growth of an individual&apos;s business network which could, in turn, promote greater economic activity. Trust assumes a very important role in developing communities where there is a significant overlap between people&apos;s social and economic networks. This paper defines the crucial role of trust in the complex interdependent relationships among social networks, cell phones and agricultural entrepreneurship. We present a diagram which illustrates that the most compelling opportunities for sustainable value creation and self-determined development in Africa may exist at the intersection of cell phones, social networks and entrepreneurship, with the necessary condition that trust, the glue that holds these elements together, is present. A capstone case-study of a nutribusiness cooperative established in the 1990s suggests the importance of social networks and trust building in an entrepreneurial venture involving rural Kenyan women. This paper provides the context for a companion research paper on the "who you know" social and economic network knowledge systems among rural women agro-entrepreneurs in Northern Tanzania and the role cell phones play within these networks. We use secondary data, including academic publications, UN datasets, business ventures and personal observations to describe the role of trust in the dynamic interdependence among entrepreneurship, social networks and cell phones that is crucial for the establishment of sustainable agricultural business ventures in East Africa
