Health Information Sources

Purpose This paper aims to investigate the role of public libraries in the dissemination of health information in the southern part of Botswana, namely, Kgatleng and Kweneng districts. It also explored how these libraries market health information services to the community they serve. The study also used health information acquisition model to get an understanding on how public library users seek health information. Design/methodology/approach The survey research design was chosen for the study and purposive sampling procedure was used to obtain the sample size of the population. The sample size consisted of 120 respondents and six interviewees. Data were collected from both library staff and users using questionnaires and interviews. Findings The results of the study showed that public libraries are striving to provide accurate and useful health information to members of the community by collecting and availing both print and electronic health information sources. The findings further indicated that public libraries have marketing programmes that they use on raising awareness of health information to their clientele. The marketing programmes include outreach, library brochures/leaflets, newsletters and library exhibitions. The results of the study also showed that there were some challenges that hindered the library users to access and use health information (e.g. lack of appropriateness of information resources and limited number of health information sources). Originality/value For a better dissemination of health information, public libraries should establish working relationships with health agencies and communication organisations or media houses with the objective of cooperative developments of collections, referrals and shared training.

The Public

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This exploratory study applied models of human information behavior and health information acquisition to the acquisition of legal information by the public. A mixed methods approach, consisting of two sequential phases, was utilized. First, an online survey consisting of 45 multiple-choice questions was administered to a Qualtrics panel of 385 individuals without formal legal training who were at least 18 years of age. In the second phase, eleven individuals who met the same screening criteria were interviewed in order to provide additional elaboration upon and clarification of the survey data. In phase 1, frequency of legal information searching and incidental discovery of legal information (information encountering, or IE) was assessed for relationships with personal, affective, contextual, and environmental factors. Findings indicate that individuals who search and encounter legal information more frequently share certain demographic and affective characteristics with their counterparts in the acquisition of health information. Age, income, and previous experience with the legal system were associated with greater legal search frequency. Age, race, and previous experience with the legal system were associated with greater frequency of legal IE. Self-efficacy and vigilance were both associated with frequency of search and IE, though perception of the legal system was not. Subjects searched and encountered more frequently because of curiosity than other situational factors. The role of risk in search and encounter frequency could not be determined. Both exposure to multiple information sources and to multiple mass media sources were associated with greater frequency of legal search and IE. In phase 2, subjects were asked about their searches and IE experiences with legal information, and the role of legal information in their everyday lives, especially as compared to health information acquisition. Findings indicate that members of the public define legal information quite narrowly as tied to lawyers and courts, rather than rights and duties (even provided with a more inclusive definition), and often fail to relate routine encounters with the law to their larger understanding of the legal system. Survey findings were corroborated in terms of source choices, the roles of previous experience, self-efficacy, and avoidance-vigilance. The increased availability of legal information sources through the internet has made it easier for people to find codes and regulations, but has not made it easier to find the information necessary to assess more complex legal issues. Other emergent themes identified in phase 2 included the detrimental effect of attorney advertising and the perception of legal information as disruptive, in contrast to the embeddedness of health information in everyday life.

Purpose – The purpose of this paper is to examine the price discovery and volatility spillovers in spot and futures prices of four currencies (namely, USD/INR, EURO/INR, GBP/INR and JPY/INR) and between futures prices of both stock exchanges namely, Multi-Commodity Stock Exchange (MCX-SX) and National Stock Exchange (NSE) in India. Design/methodology/approach – The study applies cointegration test of Johansen’s along with VECM to investigate the price discovery. GARCH-BEKK model is used to examine the volatility spillover between spot and futures and between futures prices. The other two models namely, constant conditional correlation and dynamic conditional correlation are used to demonstrate the constant and time-varying correlations. In order to confirm the volatility spillover results, the study also applies test of directional spillovers suggested by Diebold and Yilmaz (2009, 2012). Findings – The results of the study show that there is long-term equilibrium relationship between spot and futures and between futures markets. Between futures and spot prices, futures price appears to lead the spot price in the short-run. Volatility spillover results indicate that the movement of volatility spillover takes place from futures to spot in the short-run while spot to futures found in the long-run. However, the results of between futures markets exhibit the dominance of MCX-SX over NSE in terms of volatility spillovers. By and large, the findings of the study indicate the important role of futures market in price discovery as well as volatility spillovers in India’s currency market. Practical implications – The results highlight the role of futures market in the information transmission process as it appears to assimilate new information quicker than spot market. Hence, policymakers in emerging markets such as India should focus on the development of necessary institutional and fiscal architecture, as well as regulatory reforms, so that the currency market trading platforms can achieve greater liquidity and efficiency. Originality/value – Due to recent development of currency futures market, there is dearth of literature on this subject. With the apparent importance of currency market in recent time, this study attempts to study the efficient behavior of currency market by way of examining the price discovery and volatility spillovers between spot and futures and between futures prices of four currencies traded on two platforms. The study has strong implications for India’s stock market especially at the time when its currency is under great strain owing to the adverse impact of global financial crisis.
