Aiming at finding the effect of load changing on electricity market, this paper studied Cournot model with asymmetric information based on load forecasting. Firstly, a perfect competition market structure with asymmetric information was built, and a market equilibrium price was obtained based on Cournot model with no load forecasting. Then, using game theory, the impact of load forecasting on intrinsic market power is evaluated analytically based on Cournot model. Finally, the relationship between market equilibrium price, generators profits and the load forecasting result k was obtained by numerical simulation. Some insights were got from this paper. The accuracy of load forecasting will directly affect profits of investment, market equilibrium prices and market forces. And load forecasting is useful if the forecasting error rate is held under 33%. Therefore, the key is to improve the accuracy of load forecasting.

Chezum and Wimmer (2000) show the impact of asymmetric information in the American thoroughbred industry by demonstrating that homebreds (horses retained and raced by their breeders), on average, have lower betting odds than otherwise similar nonhomebreds. In this paper we test their hypothesis in the Australian thoroughbred industry. While we find no relationship between lower betting odds and homebreds when we use their model, we are still able to support their conclusion when we use a logistic model to measure the relationship between homebred and horse performance.

Parliamentary Politics

I consider how asymmetric information between the party selectorate and members of Parliament affects the renomination of incumbent candidates. By applying an adverse selection model, I argue that the selectorate looks to past performance to select candidates it expects will gain influence. However, the impact of performance varies according to the need for and availability of information. The European Parliament (EP) provides a most-likely case for information asymmetry. Studying three elections in 11 member states, I find that the allocation of influential positions in office improves chances of reselection. The effect increases when the allocation is more selective, and when the prior uncertainty around candidacies is high. The study thus proposes a new approach to the relationship between national parties and transnational groups in the EP. It also suggests venues for research on parliamentary politics and candidate selection in general.

The impact of the time aspect in planning of the maximum load and the standard capacity reserve on determination of the price for the power capacity while the competitive power selection procedure is described. The article illustrates the fundamental differences between the concepts of the load forecasting error caused by the temperature factor and forecast volume of power consumption, considering it in power capacity demand formation. The results of the impact made by these factors on the competitive power selection procedure are presented.

For long time span, the impact of many factors, uncertainties and other characteristics of mid-long term load forecasting, as well as the over-estimation of interval arithmetic, a mid-long term load forecasting method based on interval Taylor model algorithm was presented. In order to avoid misjudgment of the relationship between variables, reducing over-estimation problem, a global variable named Taylor model ID was presented to identify the independent variables and the dependent variable. The same independent variables construct the interval Taylor model only once. Use Maclaurin formula to derive the interval Taylor model of correlation function formula, and then get a quadratic exponential smoothing method based on interval the Taylor model. The proposed method has been tested on a provincial calculation. The results demonstrated the effectiveness and practical value of the approach by comparing with the results of Monte Carlo simulation and interval method.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract Administrators and supervisors face daily challenges over issues such as program funding, service fees, correct coding procedures, and the ever-changing healthcare regulations. Receiving equitable reimbursement for speech-language pathology and audiology services necessitates an understanding of federal coding and reimbursement systems. This tutorial provides information pertaining to two major healthcare coding systems and explains the relationship of these systems to clinical documentation, the Medicare Physician Fee Schedule and equitable reimbursement. An explanation of coding edits and coding modifiers is provided for use in those occasional atypical situations when the standard use of procedural coding may not be appropriate. Also included in this tutorial is a brief discussion of the impact that the Medicare Improvements for Patients and Providers Act of 2008 (HR 6331 Medicare Improvements for Patients and Providers Act [MIPPA], 2008) has had on the valuation of speech-language pathology procedure codes.

Humans are social animals; consequently, a lack of social ties affects individuals’ health negatively. However, the desire to belong differs between individuals, raising the question of whether individual differences in the need to belong moderate the impact of perceived social isolation on health. In the present study, 77 first-year university students rated their loneliness and health every 6 weeks for 18 weeks. Individual differences in the need to belong were found to moderate the relationship between loneliness and current health state. Specifically, lonely students with a high need to belong reported more days of illness than those with a low need to belong. In contrast, the strength of the need to belong had no effect on students who did not feel lonely. Thus, people who have a strong need to belong appear to suffer from loneliness and become ill more often, whereas people with a weak need to belong appear to stand loneliness better and are comparatively healthy. The study implies that social isolation does not impact all individuals identically; instead, the fit between the social situation and an individual’s need appears to be crucial for an individual’s functioning.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.
