“It is now becoming widely recognised that many of the central unresolved problems in economics turn on questions of knowledge” (Loasby, 1986, p. 41). Nearly twenty years after that was written, it may be appropriate to take a (necessarily selective) look at ideas about human knowledge and to suggest some implications for the practice of economists. The ideas with which we shall begin long predate the observation that I have just recalled; and the delay in recognising their implications indicates how the growth of knowledge is dependent on the formation of appropriate linkages – which of course are not recognised as appropriate until they have been formed. Adam Smith, Alfred Marshall and Friedrich Hayek were all confronted with the uncertain basis of knowledge before they began their study of economics; and what their responses have in common is not only a theoretical focus on the process by which people develop what we call “knowledge” but also a reliance on similar kinds of process, which result in the formation of connections within particular domains. Each author recognises the impossibility of demonstrating that any such process can deliver proven truth; instead each envisages sequences of trial and error within particular contexts, leading to the preservation of what seems to work – until it no longer does, when a new sequence of trial and error begins. In other words, they all offer evolutionary theories, Marshall and Hayek explicitly so, while Smith, directly and indirectly, had a major influence on the development of Darwin’s ideas.

The discovery of the BRCA1 and BRCA2 genes has facilitated the construction of a new group of women referred to as “previvors” – individuals who are survivors of a predisposition to cancer but who are not presently ill. These “previvors” constitute the first generation of women faced with the option to make preventative health choices based on this kind of genetic information. Therefore, this research examines how young BRCA positive women negotiate the medicalization of their bodies based on their new “potentially ill” status. Analyzing the posts in an online forum specifically for “young previvors,” the findings indicate that the majority share an “anything's better than cancer” mantra, suggesting that fear of death largely outweighs all other fears or concerns. Consequently, asserting control by taking preventative action is considered a mechanism for quelling the fear, uncertainty, and stress associated with being a BRCA gene carrier. Constructed as a medical diagnosis, carrying the BRCA mutation is consequently perceived as requiring a corresponding medical treatment. As such, despite the connection these women describe feeling with the “parts that make them a woman,” they appear to believe that they must undergo prophylactic surgery and disassociate from their bodies in order to save their lives. Ultimately, they convince themselves to view their breasts and ovaries simply as nonessential organs, rather than as core components of their feminine, sexual, and reproductive identities.

This chapter aims to discuss the issues associated with social indexing as a solution to the challenges of current information organization systems by investigating the quality and efficacy of social indexing.

The chapter focuses on the study which compared indexing similarity between two professional groups and also compared social tagging and professional indexing. The study employed the method of the modified vector-based Indexing Consistency Density (ICD) with three different similarity measures: cosine similarity, dot product similarity, and Euclidean distance metric.

The investigation of social indexing in comparison of professional indexing demonstrates that social tags are more accurate descriptions of resources and reflection of more current terminology than controlled vocabulary. Through the characteristics of social tagging discussed in this chapter, we have a clearer understanding of the extent to which social indexing can be used to replace and improve upon professional indexing.

As investment in professionally developed web directories diminishes, it becomes even more critical to understand the characteristics of social tagging and to obtain benefit from it. In future research, the examination of subjective tags needs to be conducted. A survey or user study on tagging behavior also would help to extend understanding of social indexing practices.

Information gathered from a sample of residents in four rural Pennsylvania communities is used to test the net effects of household resources (financial assets, supports, and community ties) upon respondents’ physical health and emotional well-being. Size and composition of households, types, and extent of insurance coverage, age, and aspects of household liquidity had major net effects upon physical health. Some measures of liquidity, a range of supports, and community ties had net impacts upon emotional well-being. The importance of considering the collective health needs of rural households in relation to their affordability and sustainability is stressed. The public policy implications of our results are discussed.

This chapter assesses the effects of two rural community residential advantages – economic growth and availability of health services – upon residents’ health and emotional well-being.

A de facto experimental design divided communities into four analytical types based on their economic growth and health services. Household survey data were gathered via a drop-off/pickup procedure and 400 randomly selected households were surveyed in each location. Physical health was measured with a subset of items from the Medical Outcomes Study’s 36-item short form. A 10-item emotional well-being index was used. Beyond sociodemographic items, questions concerned household assets, medical problems, social supports, and community ties. Nested regression analyses were used to assess the effects of residential advantage upon health, net of potentially confounding factors.

Contrary to expectations, both residential advantages were necessary for improved health. The most important negative net effect on health was aging. Beyond household assets and community economic expansion, miles commuted to work was the next most important factor enhancing physical health. In all types of communities, residents’ emotional well-being scores were independent of age, but positively related to household income and religious involvement.

Obviously the study is limited by geography and by the small number of communities in each residential type. While we could measure the effects of household members not being able to address all health needs, we could not assess the effects of such problems on anyone else in the households beyond the respondents. Our survey approach is also unable to address the effects of rural residents being unable to meet their health needs over time.

Ours is the first study that we know of applying a de facto natural experimental design to assess community residential effects. The interrelated effects of residential community resources for residents’ health suggests that more studies like this one should be done.

Much of the extant literature has focused heavily on the recruiting aspects of college sports (Beamon, 2008; Broughton, E., & Neyer, M. (2001). Advising and counseling student athletes. New Directions for Student Services, 93, 47–53). Far less attention has been given to the supply chain of athletic departments from a macro-level perspective. A supply chain is a stream of information or goods from a supplier to an end customer. This study will provide a synthesis of previous literature, which will be integrated into a conceptual framework explaining the college athlete supply chain and its impact on Black males. We will also utilize secondary data to examine the organizational development of college recruiting and the conceptual nature of college athlete suppliers and manufacturers. The chapter will conclude with recommendations on how best to address the issues of the supply chain where revenue in college football has taken precedence over the collegiate experiences of many Black male student-athletes. This knowledge will be essential to all stakeholders within college athletics, particularly administrators, athletes, recruiters, coaches, and parents of athletes.

National differences in the demand for voluntary external audits have been linked to multiple factors, such as differences in a country's rate of growth, access to external credit, and institutional quality. Audits, however, also have a psychological cost, whose intensity is genetically and culturally hereditary. Using a sample of 3,072 private firms across 34 industries in seven countries, including five countries or regions from the former Soviet Comecon, we find that a country's share of firms choosing to undergo external audits is negatively related to the prevalence of carriers of the G allele in the mu-opioid receptor gene's A118G polymorphism, also known as the “social sensitivity” gene. Furthermore, the relationship between the prevalence of the social sensitivity gene and audits is fully mediated by a national culture's degree of collectivism. The results are statistically and economically highly significant and remain robust to the introduction of a set of confounding factors at the firm and country levels. Our results have practical relevance in recognizing psychological diversity when conducting audits and, more generally, preventing burnout in the workplace.
