This article brings together insights on the global challenges of achieving a safe food system. Through looking at examples of food safety initiatives, relevant success factors are identified and then distilled into five essential elements for developing a robust and safe food system. While much of the work in this area looks at government initiatives, this article looks particularly at industry-led initiatives. The article includes a brief look at the importance of food in Chinese culture and the current structure of the Chinese food chain. Specific initiatives from other markets are reviewed, and the five elements are outlined. 相似文献

The appropriateness of default investment options in defined contribution plans: Australian evidence
For participants in defined contribution (DC) plans who refrain from exercising investment choice, plan contributions are invested following the default investment option of their respective plans. Since default investment options of different plans vary widely in terms of their benchmark asset allocation, the most important determinant of investment performance, participants enrolled in these options face significantly different wealth outcomes at retirement. This paper simulates the terminal wealth outcomes under different static asset allocation strategies to evaluate their relative appeal as default investment choice in DC plans. We find that strategies with low or moderate allocation to stocks are consistently outperformed in terms of upside potential of exceeding the participant's wealth accumulation target at retirement as well as downside risk of falling below that target outcome by aggressive strategies whose allocation to stocks approach 100%. The risk of extremely adverse wealth outcomes for plan participants also does not appear to be very sensitive to asset allocation. Our evidence suggests the appropriateness of strategies heavily tilted towards stocks to be nominated as default investment options in DC plans unless plan providers emphasize predictability of wealth outcomes over adequacy of retirement wealth. 相似文献

This paper describes and develops a model for calculating location-based strategic values of foreclosed properties considered for acquisition and redevelopment by community development corporations (CDCs). A property’s strategic value refers to its proximity to site-specific neighborhood amenities and disamenities (e.g. schools, public transit, distressed properties), given the relative importance of that proximity to CDC organizational and community objectives. We operationalize the concept of strategic value, and apply this concept to a salient public sector decision problem. Using data and value assessments from a CDC engaged in foreclosed housing redevelopment, we compute measures of strategic value for a set of acquisition candidates. We show that strategic values can differ in systematic ways depending on the types of amenities and disamenities identified as relevant for CDC acquisition decisions, the relative importance assigned to those amenities and disamenities, and the utility maximization objectives of the CDC. We conclude by proposing a multi-criteria decision model for foreclosed housing acquisition and redevelopment which incorporates a theory of residential housing impacts for which strategic value measures are a special case. 相似文献

Coaching the alpha male 总被引:3,自引:0,他引:3
Highly intelligent, confident, and successful, alpha males represent about 70% of all senior executives. Natural leaders, they willingly take on levels of responsibility most rational people would find overwhelming. But many of their quintessential strengths can also make alphas difficult to work with. Their self-confidence can appear domineering. Their high expectations can make them excessively critical. Their unemotional style can keep them from inspiring their teams. That's why alphas need coaching to broaden their interpersonal tool kits while preserving their strengths. Drawing from their experience coaching more than 1,000 senior executives, the authors outline an approach tailored specifically for the alpha. Coaches get the alpha's attention by inundating him with data from 360-degree feedback presented in ways he will find compelling--both hard-boiled metrics and vivid verbatim comments from colleagues about his strengths and weaknesses. A 360-degree assessment is a wake-up call for most alphas, providing undeniable proof that their behavior doesn't work nearly as well as they think it does. That paves the way for a genuine commitment to change. In order to change, the alpha must venture into unfamiliar--and often uncomfortable--psychological territory. He must admit vulnerability, accept accountability not just for his own work for others', connect with his underlying emotions, learn to motivate through a balance of criticism and validation, and become aware of unproductive behavior patterns. The goal of executive coaching is not simply to treat the alpha as an individual problem but to improve the entire team dynamic. Initial success creates an incentive to persevere, and the virtuous cycle reverberates throughout the entire organization. 相似文献

Pharmacy costs continue to rise, as does the number of senior citizens. One of the ways of containing costs may be the pharmacy discount drug card program, for both seniors and the general population. 相似文献

The financial crisis of 2008 was significantly influenced by housing, mortgage markets and mortgage-backed securities (MBS).
The Federal Reserve (Fed) conducts temporary open market operations on a daily basis and frequently uses repos on MBS. With
this daily interaction with MBS, we examine whether any signal about the impending financial crisis could have been seen in
the Fed’s temporary open market operations. We identify four anomalous events in MBS temporary open market operations and
examine those events for signals of the financial crisis. We find nothing in the four events that would have provided signals
of the financial crisis. Instead, the common feature of the four events is an unusually large supply of MBS made available
to the Fed for those day’s temporary open market operations. 相似文献

This article explores the importance of image to the Atlanta Olympic Games of 1996. It suggests that the event must be seen as an example of the use of the propagation of selected images designed to boost the standing of the city in an increasingly competitive interurban environment. The intersection of major sporting spectacles, big business and vastly increased television coverage provides an important new medium through which boosterists can put their city on the world map. However, as the Atlanta case reveals, the ‘semiotics of the successful city‘ involves a highly ideological construction which often presents urban areas as conflict‐free zones. In Atlanta, potentially negative images were removed both physically and symbolically from the urban landscape, while the actual experience of the Games suggested that the city had some way to go in material terms to match its often hyperbolic self‐promotion. The article suggests that the staging of events such as the Olympics is a necessarily high‐risk venture for cities, one that, as in the case of Atlanta, may not have been ultimately worth the effort. Cet article examine l'importance de l'image dans le cadre des Jeux Olympiques d'Atlanta de 1996. Il propose de considérer l'événement comme un exemple de la diffusion d'images sélectionnées, conçues et utilisées afin de promouvoir la réputation de la ville dans un contexte interurbain de plus en plus concurrentiel. L'intersection entre des spectacles sportifs exceptionnels, de grandes entreprises et une couverture télévisuelle considérablement étendue constitue un moyen novateur grâce auquel les promoteurs de cette dynamique peuvent positionner leur ville sur la carte du monde. Cependant, comme le montre le cas d'Atlanta, la ‘sémiotique d'une ville gagnante’ implique une construction idéologique très forte qui présente souvent les zones urbaines comme des espaces non conflictuels. À Atlanta, les images à potentiel négatif ont étééliminées à la fois physiquement et symboliquement du paysage urbain, tandis que les Jeux eux‐mêmes laissaient à penser que la ville devait progresser sur le plan matériel si elle voulait correspondre à son auto‐promotion souvent hyperbolique. L'article suggère que la mise en scène d'événements tels que les Jeux Olympiques est une opération nécessairement très risquée pour des villes, opération qui, à l'instar de l'expérience d'Atlanta, peut finalement ne pas justifier les efforts réalisés. 相似文献

This study compares the performance of the ISD, the GARCH (1,1) , the historical volatility estimates and of two lagged trading volume measures for predicting the Swiss Stock Market Index's (SMI) volatility. The ISD has a superior daily informational content than the GARCH (1,1) estimate and retains unbiased but decreasing explanatory power over up to 20 days ahead horizons. Mean and spread daily volume measures play a significant correcting role when forecasting stock market volatility over daily and longer intervals respectively and clearly dominate the GARCH (1,1) forecasts. Their significance emphasises heterogeneous horizon traders' influence on the SMI volatility time series properties 相似文献
