The objective and aim of the study was to compile empirical data to quantify the underestimation of the true burden of drowning and to compare drowning rates using commonly reported codes compared with those revealed by use of the full range of drowning codes in ICD version 10. The authors reviewed mortality data (1999-2002) from Australia and the USA and compiled data to compare the burden of 'unintentional drowning' with that of 'all drowning'. In both Australia and the USA, drowning mortality is more than 35% higher when a full range of codes is examined. A more comprehensive representation of the drowning problem is needed to assist in strengthening prevention activities. 相似文献

Examination of 41 closed-end fund initial public offerings (IPOs)during the period from January 1986 to June 1987 reveals thatthe mean initial day's return is not significantly differentfrom zero in contrast to previous findings for nonfund IPOs.New funds also show significant negative after-market returnsunlike other new issues. Despite the disparity between our findingsand previous results, our results are consistent with existingmodels. 相似文献

Social network analysis (SNA) has become increasingly popular in many scientific applications and is applied widely in human resource development (HRD) research. Leveraging social networks can influence learning processes within organizations and provide opportunities for problem‐solving and the generation of new ideas. This article offers a look at the methodological basics of analyzing social networks and the major concepts in social capital theory from the social network perspective. A practical case is made to use SNA in the HRD context. After an analysis of hypothetical network data and application of social capital theory, the case shows how some actors in the network can create social capital from strong supportive relations, whereas others might expect to gain brokerage advantages by playing a role in structural holes. This article also serves as a brief guide for beginners using SNA with R in HRD research. 相似文献

Degradation of arid rangeland, and efforts to control that degradation, have become topical issues. However, the inherent characteristics of the rangeland, and the intertemporal nature of the problem, complicate the analysis of degradation issues in the search for more appropriate rangeland policies. Stochastic dynamic programming is examined as one means of allowing for those complexities. Using the case of the Queensland mulga rangelands, optimal stocking rates are shown to rise with lower property sizes, higher discount rates, higher wool prices and declining risk aversion. Importantly, the analysis reveals that a strategy of high stocking rates with the potential for rangeland degradation is an optimal response to the economic and social factors that confront graziers and is not an intertemporal information problem alone. 相似文献

This paper develops a game-theoretic model of mortgage securitization, which is then used to examine a potential effect of automated underwriting. The paper's primary supposition is that automated underwriting lowers the costs to competitive mortgage originators and a monopolist securitizer of identifying mortgage applicants who are good credit risks. Faced with lower underwriting costs, originators will screen a larger number of mortgage applicants in the hopes of holding more good risks in their portfolios and passing through more bad risks to the securitizer. This mounting adverse-selection problem causes the securitizer's expected revenues to decline; this effect can outweigh the cost-saving benefit of automated underwriting, causing the securitizer's return on equity to fall. 相似文献

We conduct an empirical analysis of the Federal Reserve's large‐scale asset purchases (LSAPs) on mortgage‐backed securities (MBS) yields and mortgage rates. We estimate a cointergrated, error‐correction model that links Federal Reserve securities purchases and stocks of Treasury and MBS securities to equilibrium MBS yields and mortgage rates. The Federal Reserve's accumulation of MBS and Treasury securities lowered MBS yields and mortgage rates by more than what would have been suggested by changes in market expectations alone, suggesting that portfolio rebalancing effects of LSAPs are an important consideration for monetary policy transmission. Our estimates also suggest that the Federal Reserve must hold a substantial market share of agency MBS or of Treasury securities to significantly lower MBS yields and in turn significantly lower mortgage rates. 相似文献
