Conditioning Information and European Bond Fund Performance

EUROPEAN FINANCIAL MANAGEMENT, Issue 2 2003
Florinda Silva
G11; G12; G14 In this paper we evaluate the performance of European bond funds using unconditional and conditional models. As conditioning information we use variables that we find to be useful in predicting bond returns in the European market. The results show that, in general, bond funds are not able to outperform passive strategies. These findings are robust to whatever model (unconditional versus conditional and single versus multi-index) we use. The multi-index model seems to add some explanatory power in relation to the single-index model. Furthermore, when we incorporate the predetermined information variables, we can observe a slight tendency towards better performance. This evidence is consistent with previous studies on stock funds and comes in support of the argument that conditional models might allow for a better assessment of performance. However, our results suggest that the impact of additional risk factors seems to be greater than the impact of incorporating predetermined information variables. [source]

Effectiveness of educational interventions on the improvement of drug prescription in primary care: a critical literature review

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 2 2001
Adolfo Figueiras PhD
Abstract This paper is a critical review of studies of educational programmes designed to improve prescription practices in ambulatory care. Scientific articles were selected from the following bibliographical indices: MEDLINE, IME, ICYT and ERIC. The searches covered the time period between 1988 and 1997. The search criteria included: primary-care, educat*, prescription* and other related keywords. The inclusion criteria were studies describing educational strategies aimed at general practitioners working in ambulatory settings. The study outcome was change in prescribing behaviour of physicians through prescribing indicators. The following data were extracted: study design, target drugs, type of intervention, follow-up period of the prescription trends, type of data analysis, type of statistical analysis and reported results. We found 3233 articles that met the search criteria. Of these, 51 met the inclusion criteria and 43 studied the efficacy/effectiveness of one or various interventions as compared to no intervention. Among seven studies evaluating active strategies, four reported positive results (57%), as opposed to three of the eight studies assessing passive strategies (38%). Among the 28 studies that tested reinforced active strategies, 16 reported positive results for all variables (57%). Eight studies were classified as a high degree of evidence (16%). We concluded that the results of our review suggest that the more personalized, the more effective the strategies are. We observe that combining active and passive strategies results in a decrease of the failure rate. Finally, better studies are still needed to enhance the efficacy and efficiency of prescribing practices. [source]

Childhood unintentional injuries: the perceived impact of the environment, lack of supervision and child characteristics

CHILD: CARE, HEALTH AND DEVELOPMENT, Issue 3 2006
S.-A. Munro
Abstract Background Investigations into the context and causation of injury, including injury risks, are an essential part of the injury prevention knowledge base. Caregiver perceptions of childhood injury risks may assist in the design of safety interventions and influence the way in which an intervention is received within a community. Methods Focus groups and individual interviews were conducted in two low-income neighbourhoods in South Africa to collect information on caregiver perceptions of injury risks. The data were analysed via thematic content analysis. Results The results revealed that injury risks are perceived as multifaceted and as contributing synergistically to an injury event. Parents of children also tended to attribute most risks to the environment instead of individual action. Conclusions Interventions including passive strategies and less activity from the parent may be welcomed in communities. Attention should be given to child injury prevention methods specifically for low-income contexts. [source]

Heart rate and blood pressure responses to a competitive role-playing game

AGGRESSIVE BEHAVIOR, Issue 5 2001
J. Ricarte
Abstract The effects of the outcome of competitive encounters on physiological parameters have been studied, especially testosterone levels, but hardly on other systems that, however, present a high sensitivity to stress. This study assessed the effect of a competitive game on heart rate (HR) and blood pressure (BP) in a sample of university students. In addition, the influence of anxiety and attributions of the outcome was also explored. Only winners significantly showed a rise in HR during the competition followed by a decrease along the posttask phase in addition to more internal attributions. On the contrary, the average HR for losers during the competition was lower compared with their baseline values. No differences depending on the outcome were found in BP. The cardiovascular response as well as the subjective interpretation of the outcome suggest a more active strategy employed by winners vs. a more passive strategy of losers. Future studies should specifically investigate the importance of coping strategies for psychophysiological adaptation to contests and for the outcome reached. This would permit an advance in the understanding of the role of individual differences in the processes of stress and in associated diseases. Aggr. Behav. 27:351,359, 2001. © 2001 Wiley-Liss, Inc.

Relationships between Australian real estate and stock market prices,a case of market inefficiency

JOURNAL OF FORECASTING, Issue 3 2002
John Okunev
Abstract This paper explores the relationship between the Australian real estate and equity market between 1980 and 1999. The results from this study show three specific outcomes that extend the current literature on real estate finance. First, it is shown that structural shifts in stock and property markets can lead to the emergence of an unstable linear relationship between these markets. That is, full-sample results support bi-directional Granger causality between equity and real estate returns, whereas when sub-samples are chosen that account for structural shifts the results generally show that changes within stock market prices influence real estate market returns, but not vice versa. Second, the results also indicate that non-linear causality tests show a strong unidirectional relationship running from the stock market to the real estate market. Finally, from this empirical evidence a trading strategy is developed which offers superior performance when compared to adopting a passive strategy for investing in Australian securitized property. These results appear to have important implications for managing property assets in the funds management industry and also for the pricing efficiency within the Australian property market.
