MANAGING PHOSPHOROUS SOIL DYNAMICS OVER SPACE AND TIME
Understanding the relationship between soil fertility dynamics and crop response is conceptually appealing. Even more appealing is comprehension of the spatial and temporal heterogeneity of these connections over a production surface and across seasons. Knowledge of these interactions is complicated because nutrient carryover dynamics and crop response to inputs are determined simultaneously on the one-hand, and sequentially on the other. A second problem enters when crops are rotated, for example, in the corn-soybean system commonly practiced in the Corn Belt. This paper examines the nutrient carryover-crop response nexus using data from a corn-soybean, variable-rate nitrogen (N) and phosphorous (P) experiment conducted over five years. Site-specific corn response to N and P and soybean response to P are simultaneously estimated with a P carryover equation. These estimates are used in a dynamic programming model to map site-specific optimal N and P fertilizer policies, soil P evolution, and profitability. The net present value of managing N and P site-specifically is compared to a strategy where these inputs are managed uniformly following extension guidelines. The results suggest that when P-carryover is managed, site-specific returns to the variable-rate strategies are higher than returns to a conventional, uniform strategy.Crop Production/Industries,
Managing Your Time (1993)
"Reviewed October 1, 1993."No one has enough time. Time is a unique resource as it cannot be accumulated like money or stock-piled like materials. We spend it at a fixed rate. Since all of us have exactly the same amount of time, the real problem is not how much we have, but how we use our time. How well it is used often determines the manager's success

Managing myself: investigator survival in sensitive research
Thirteen years of investigative research into sexual abuse in sport provides the basis for this paper, in which reflections are offered about the role and survival of the investigator in sensitive research. The ethical ground rules, research methods and working practices adopted during this research have all been influenced by processes well beyond conventional social science. The paper interrogates three meanings of âmanaging myselfâ as a lesbian engaged in a gendered research process: first, managing myself, coping with the strains and stresses of the research; secondly, managing (by) myself as being alone in the research; and thirdly, managing my âself/selvesâ, deciding which of several possible selves or agendas - the personal, the scientific or the political â is being addressed at any given time. The paper ends by considering how to maintain focus in the face of internal doubts and external pressures
Customers Suffer From Employee Churn: High Turnover Makes It Harder to Provide Top Service
Key Findings:
⢠As rates of voluntary turnover climb within key business units, customers are more likely to report bad customer service.
⢠When new workers arrive, established workers have to take time away from customer service to train the new workers in procedures and company culture.
⢠Work units with lots of new employees have more trouble managing turnover and receive the lowest customer service ratings.
⢠Bigger may not be betterâlarger work units have particular difficulty managing turnover and receive lower customer service scores than smaller ones.
⢠A tight, cohesive work group seems to suffer from turnover as much as a less-bonded group
The value of coskewness in evaluating mutual funds
Recent asset pricing studies demonstrate the relevance of incorporating the coskewness in Asset
Pricing Models, and illustrate how this component helps to explain the time variation of ex-ante
market risk premiums. This paper analyzes the role of coskewness in mutual funds performance
evaluation. We find evidence that adding a coskewness factor is economically and statistically
significant. We document that some managers are managing the coskewness and show, in general,
a persistent behaviour on time in their coskewness policy. One of the most striking results is that
many negative (positive) alpha funds measured relative to the CAPM risk adjustments would be
reclassified as positive (negative) alpha funds using a model with coskewness. Therefore, a ranking
of funds based on risk adjusted returns without considering coskewness would generate an
erroneous classification. Moreover, some fund characteristics, such as the turnover ratio or the
category, are related to the likelihood of managing coskewness
Working Notes from the 1992 AAAI Spring Symposium on Practical Approaches to Scheduling and Planning
The symposium presented issues involved in the development of scheduling systems that can deal with resource and time limitations. To qualify, a system must be implemented and tested to some degree on non-trivial problems (ideally, on real-world problems). However, a system need not be fully deployed to qualify. Systems that schedule actions in terms of metric time constraints typically represent and reason about an external numeric clock or calendar and can be contrasted with those systems that represent time purely symbolically. The following topics are discussed: integrating planning and scheduling; integrating symbolic goals and numerical utilities; managing uncertainty; incremental rescheduling; managing limited computation time; anytime scheduling and planning algorithms, systems; dependency analysis and schedule reuse; management of schedule and plan execution; and incorporation of discrete event techniques
