Some Theoretical Foundations for Conflict Methodology

Propositions from information theory, social psychological theory and modern systems theory are used as the theoretical foundations for grounding principles of conflict methodology. Fifteen principles of conflict methodology are generated. The role of conflict research in entering back into the construction of social reality is also discussed.     

Recent health trends in the Native American population

This paper reviews the changes in the health status of Native Americans since the mid-1950s, how the disease pattern differs from non-Natives, and regional differences within the Native American population. Despite some limitations, data from the Indian Health Service indicate that substantial decline in the infant mortality rate and mortality from such infectious diseases as tuberculosis and gastroenteritis has occurred. With the exception of cardiovascular diseases and cancer, the risk of death from most causes are higher among Native Americans than the total US population. Geographic variation in disease rates can be demonstrated, most notable in diabetes. The unique pattern of diseases among Native Americans reflect the interaction of environmental and genetic factors. Genetic susceptibility plays a significant role in some diseases, such as diabetes, while for others, the generally lower socioeconomic status, higher prevalence of certain health risk behaviors and lower utilization of preventive services in the Native American population are important determinants.     

A Simple Estimator of Error Correlation in Non-parametric Regression Models

Abstract.  It is well known that major strength of non-parametric regression function estimation breaks down when correlated errors exist in the data. Positively (negatively) correlated errors tend to produce undersmoothing (oversmoothing). Several remedies have been proposed in the context of bandwidth selection problem, but they are hard to implement without prior knowledge of error correlations. In this paper we propose a simple estimator of error correlation which is ready to implement and reports a reasonably good performance.     

AN EXPLORATORY STUDY OF PATTERNS OF PRIORITIES AND TRADE-OFFS AMONG OPERATIONS MANAGERS

A survey of 15 firms showed that agreement among operations managers on competitive priorities is related to agreement on long-run strategic trade-off decisions and not to agreement on shortrun trade-offs. Furthermore, intended short-run actions were often in conflict with stated competitive priorities. Use of management-by-objectives linked to performance appraisal was related to agreement on competitive priorities.     

The Conditioning Treatment of Childhood Enuresis

Summary Enuresis is described as a learning deficiency and conditioningtreatment discussed as the logical positive outcome. The processof conditioning treatment is described and compared, and commonobjections discussed. Explanation is given of the practicalapplication of conditioning treatment in social casework andresidential child care     

STRUCTURAL CHANGE, COMPETITIVE BALANCE, AND THE REST OF THE MAJOR LEAGUES

Analyzing North American major sports leagues other than baseball, we find no break points in competitive balance time series corresponding to rule changes, the draft, free agency, salary caps, or labor disputes except for the 1998 basketball lockout. Some expansion and team relocation correspond with break points. Mergers that do correspond with break points all enhance competitive balance. But not all expansions, moves, and mergers correspond with break points. Remaining explanatory challenges include a general negative trend in competitive balance in basketball and the occurrence of a break point in football, 1976–1977. ( JEL C32, L83)     

TRANSACTION COST, TWO-PART TARIFFS, AND COLLUSION

When two goods exhibit demand complementarity, the sellers would generally charge lower prices under collusion than under rivalry–a cartel internalizes cross effects that independent firms ignore. For the particular case of "two-part" tariffs consisting of entrance fees and per-unit prices, this paper shows that entrance fees are indeed lower under collusion than under rivalry, but that per-unit prices are unaffected. The demand complementarity arises from transaction costs borne by consumers who enter the market. The policy implication is that collusion can be socially preferable to competition in the presence of such transaction costs.     

SIGNAL EXTRACTION AND RATIONAL INATTENTION

In this paper we examine the implications of two theories of informational frictions, signal extraction (SE) and rational inattention (RI), for optimal decisions and economic dynamics within the linear‐quadratic‐Gaussian (LQG) setting. We first show that if the variance of the noise and channel capacity (or marginal information cost) is fixed exogenously in the SE and RI problems, respectively, the two environments lead to different policy and equilibrium asset pricing implications. Second, we find that if the signal‐to‐noise ratio and capacity in the SE and RI problems are fixed, respectively, the two theories generate the same policy implications in the univariate case, but different policy implications in the multivariate case. We also show that our results do not depend on the presence of correlation between fundamental and noise shocks. We then discuss the applications to macroeconomic models of permanent income and price‐setting. (JEL C61, D81, E21)     

Factors Associated with Recreational Gambling Frequency among Older Adults

Although a steady increase in the number of legalized gambling venues is occurring, few studies have empirically investigated the determinants of recreational gambling frequency among older adults. This investigation is based on a random-digit dialling sample of 290 residents 55 and older in the Las Vegas, Nevada, USA area whom self-reported that they currently gamble, had moved to Las Vegas after the age of 18, and were not problem or pathological gamblers. Using ordinal regression methods, we examined the impact upon gambling frequency of the following factors: age when moved to the community; considerations motivating in-migration to the community; and social interaction during gambling; as well as age; sex; income; and marital status. Results indicate that more frequent gamblers are single, male, 55–60 years old, gamble with friends, moved to Las Vegas to live after the age of 40 and for whom gambling was an important motivation for moving to Las Vegas.
