Role of Government in an Era of Total Quality Management (TQM) and Globalization: Challenges and Opportunities

This article addresses the changing role of government in the rapidly changing environment of globalization, a process through which worldwide integration is pursued by forces of global capitalism. Government is challenged by conflicting and contradictory forces of globalization of corporate capitalism seeking absolute profit, while at the same pressures for quality services and quality assurance are mounting worldwide. As a result, an impossibility theorem develops, with new challenges and opportunities facing governments. Alternative theories of government are presented, and suggestions are offered on what government should do to promote quality assurance and TQM in the age of globalization.

THE BOOTSTRAP RISK OF LINEAR EMPIRICAL BAYES ESTIMATES

This paper discusses the bootstrap risk of the linear empirical Bayes estimate of the form θ=Ǎ+B̌x, where x is the current observation, and Ǎ and B̌ are generally functions of the estimates of the prior parameters. The standard error of this risk is developed and ‘computations’ of both the bootstrap risk and its standard error are made.     

A half circular distribution for modeling the posterior corneal curvature

The posterior corneal curvature and many other medical, environmental, and ecological variables are measured with angles where its range is less than π. Such data are so-called axial or half circular data. Half circular data modeling has not received much attention from researchers. This paper proposes a new half circular distribution model based on inverse stereographic projection technique of Burr-XII distribution. The maximum likelihood estimates of parameters are obtained and a simulation study to evaluate the performance of estimates was carried out. The application on the posterior corneal curvature of 23 patients shows that the proposed distribution fits the data well.     

The inverted Nadarajah–Haghighi distribution: estimation methods and applications

The inverted (or inverse) distributions are sometimes very useful to explore additional properties of the phenomenons which non-inverted distributions cannot. We introduce a new inverted model called the inverted Nadarajah–Haghighi distribution which exhibits decreasing and unimodal (right-skewed) density while the hazard rate shapes are decreasing and upside-down bathtub. Our main focus is the estimation (from both frequentist and Bayesian points of view) of the unknown parameters along with some mathematical properties of the new model. The Bayes estimators and the associated credible intervals are obtained using Markov Chain Monte Carlo techniques under squared error loss function. The gamma priors are adopted for both scale and shape parameters. The potentiality of the distribution is analysed by means of two real data sets. In fact, it is found to be superior in its ability to sufficiently model the data as compared to the inverted Weibull, inverted Rayleigh, inverted exponential, inverted gamma, inverted Lindley and inverted power Lindley models.     

Forecasting demand for food in Libya—using confidence limits

Many developing countries are not self-sufficient in food production and they depend on food imports. In order to plan imports well in advance, the demand for food must be forecasted. If the forecasts are too low, the people suffer. On the other hand if the forecasts are too high—the food being a perishable commodity—resources of the country are wasted. The Food and Agricultural Organization of the United Nations (FAO) undertakes such forecasts occasionally. The FAO however links the food consumption to the income of a country and then just assume future income. Such forecasts have no scientific validity and could both fall short or be grossly excessive. In this study, the methodologies of Time Series and Regression Analysis are combined to avoid any guesses. Then confidence intervals are built so that it can be stated, e.g. with 95 per cent confidence that a nation will not eat more than the amount specified. A comparison of costs is made and it is shown that a country can save millions of dollars through the method of statistical confidence limits rather than by adding arbitrary quantities to means and averages. Finally savings possible in some other developing countries, by adopting the proposed method, are tabulated.     

Reaching the U.S. Cell Phone Generation: Comparison of Cell Phone Survey Results with an Ongoing Landline Telephone Survey

Noncoverage rates in U.S. landline-based telephone samples dueto cell phone only households (i.e., households with no landlinebut accessible by cell phone) and the corresponding potentialfor bias in estimates from surveys that sample only from landlineframes are growing issues. Building on some of the few publishedstudies that focus on this problem, a study was conducted inthree states (Georgia, New Mexico, and Pennsylvania) as partof the Behavioral Risk Factor Surveillance System (BRFSS), theworld's largest ongoing public health telephone survey, to evaluatethe effectiveness of conducting the BRFSS interview with a sampledrawn from dedicated cell phone telephone exchanges and mixed-use(landline and cell phone) exchanges. Approximately 600 interviewswere conducted in each of two groups: cell phone only adults(n = 572) and adults with both a landline and a cell phone (n= 592). Making comparisons with data from the ongoing, landline-basedBRFSS survey, we report on response rates, demographic characteristicsof respondents, key survey estimates of health conditions andrisk behaviors, and survey costs. The methods used in this studyhave wide application for other U.S. telephone surveys.     

Effects of aging on Type II muscle fibers: a systematic review of the literature

The authors conducted a systematic review of the literature for scientific articles in selected databases to determine the effects of aging on Type II muscle fibers in human skeletal muscles. They found that aging of Type II muscle fibers is primarily associated with a loss of fibers and a decrease in fiber size. Morphological changes with increasing age particularly included Type II fiber grouping. There is conflicting evidence regarding the change of proportion of Type II fibers. Type II muscle fibers seem to play an important role in the aging process of human skeletal muscles. According to this literature review, loss of fibers, decrease in size, and fiber-type grouping represent major quantitative changes. Because the process of aging involves various complex phenomena such as fiber-type coexpression, however, it seems difficult to assign those changes solely to a specific fiber type.     

Corporate Diversification,Information Asymmetry and Insider Trading

The literature suggests that corporate diversification destroys firm value. This value destruction is usually considered to be a consequence of managers' pursuing diversification strategies to benefit themselves rather than to increase firm value. This paper provides evidence that casts doubt on this agency theory‐based explanation for corporate diversification. Evidence based on insider trading suggests that managers themselves consider their diversification strategies to be value‐increasing. Specifically, it is documented that corporate insiders (directors) purchase more of their firms' shares in the open market when corporate diversification is high. Moreover, insiders purchase more when the level of diversification discount is high, suggesting that they disagree with outside investors' undervaluation due to diversification. It is also found that the market reaction to insiders' purchases is positively related to corporate diversification. This result suggests that outsiders consider the amount of favourable information contained in insiders' purchases to increase with the extent of corporate diversification.     

A Tale of Two Seasons: Participation and Medal Counts at the Summer and Winter Olympic Games*

Objectives. This article examines all postwar Summer and Winter Olympic Games in order to investigate the economic and political determinants of participation and medal‐winning success. Methods. Using newly compiled data, regression analysis gives intuitive results with surprisingly accurate predictions beyond the historical sample. We also estimate the rise in income per capita required to send an extra participant, and the “cost” in GDP per capita of an extra medal. Results. Compared to the Summer Games, Winter participation levels are driven more by income and less by population, have less host nation bias, and a greater effect of climate. Single‐party and communist regimes win more medals in both seasons. Conclusion. Although their effects differ with the season of the Games, socioeconomic variables explain Olympic participation and success remarkably well.     

Multiple‐Family Group Intervention for Incarcerated Male Adolescents Who Sexually Offend and Their Families: Change in Maladaptive Emotion Regulation Predicts Adaptive Change in Adolescent Behaviors

The multiple‐family group intervention is an effective, yet affordable, 8‐week treatment that is conducted in a juvenile correctional institution in Alabama with adolescents who sexually offend and their families. Data from 115 incarcerated male adolescents and their male and female caregivers collected at pre‐, post‐, and 1‐year follow‐up were used to determine that problem behaviors (internalizing, externalizing) decreased over pre‐ and posttest and the significant decreases in maladaptive emotion regulation predicted those changes. Adolescent‐reported anxiety over abandonment and attachment dependence on parents increased significantly; these changes were predicted by decreases in maladaptive emotion regulation. Linear growth models were also fit over the 3 time points and indicate decreases in adolescent problem behavior and maladaptive emotion regulation.
