Physicians lead the way at America's top hospitals

The 100 Top hospitals are selected annually based on seven critical parameters for each of the 6,200-plus U.S. hospitals with 25 or more beds. They include the previous year's risk-adjusted patient mortality and complication rates, severity-adjusted average patient lengths of stay, expenses, profitability, proportional outpatient revenue, and asset turnover ratio (a measure of facility and technological pace-keeping ability). The winners are selected from five comparable size groupings--small, medium, large community, teaching, and large academic hospitals. Conspicuous among the winners at every level are physician-led organizations. Even in the majority of hospitals headed by non-physician administrators, however, the managerial capabilities of medical directors are the key to success. The most common characteristic of these award-winning hospitals is that the leadership is working together and communicating the institution's goals effectively to all levels of the organization.     

The urban-rural interface: Urbanization and tropical forest cover change

A considerable body of empirical and theoretical literature on the causes of tropical deforestation has emerged over the last twenty years. Recognizing that small-farmers in the Amazon Basin are a key agent in the process of primary forest conversion, a growing genre of studies at the household level have attempted to quantify the influence of various factors on small-farmer land-use decisions. Many of these studies have acknowledged the seeming importance of urban centers as hubs of propulsive activity and information, yet none have comprehensively captured the urbanization factor in rural land use decisions. I argue that this methodological shortcoming in empirical work to-date reflects an inadequate conceptualization of the range of urban-based networks and their inter-relationships. In an effort to overcome this roadblock to further empirical discovery, I review several leading schools of thought that might be pressed into service in developing a framework for interpreting the urban influences on rural landscapes. I call this construct the Urban-Rural Interface. This is not a complete theoretical model or a unique methodology, but rather an initial effort to develop a general framework from which more sophisticated formulations might proceed.     

Testing a new model of mentoring

Mentoring programs are effective only when mentors become significant adults in the lives of youth. Mentors who achieve this status provide support that helps youth develop important psychological and behavioral assets, such as self-esteem and the ability to cope, thus promoting healthy adjustment. These processes are evident in findings of an evaluation of outcomes in a Big Brothers Big Sisters of America program.     

Accounting for the man-information interface in management information systems

A primary cause for the failure of both formal and informal management information systems to live up to expectations stems from the designer's lack of awareness or improper conception of the interfaces existing between information and man, its user. This underscores the need for a better understanding of the relationship between man, psychologically and sociologically, and information. The results of several experiments performed in a simulated financial setting are presented as illustrations of human information processing tendencies in both individuals and committees. Design options to attenuate human foibles and limitations and to counterveil propensities to subvert systems are discussed. Areas for further research are suggested.     

A Note on Analysing Time Series Data which Accumulate Over Unequal Observation Intervals

The problem of analysing flow series observed over unequal periods of time is discussed, and a suggestion is made for dealing with situations where the lengths of the periods follow a simple pattern
