A data-mining-based methodology for transmission expansion planning

In recent decades, all over the world, competition in the electric power sector has deeply changed the way this sector’s agents play their roles. In most countries, electric process deregulation was conducted in stages, beginning with the clients of higher voltage levels and with larger electricity consumption, and later extended to all electrical consumers. The sector liberalization and the operation of competitive electricity markets were expected to lower prices and improve quality of service, leading to greater consumer satisfaction. Transmission and distribution remain noncompetitive business areas, due to the large infrastructure investments required. However, the industry has yet to clearly establish the best business model for transmission in a competitive environment. After generation, the electricity needs to be delivered to the electrical system nodes where demand requires it, taking into consideration transmission constraints and electrical losses. If the amount of power flowing through a certain line is close to or surpasses the safety limits, then cheap but distant generation might have to be replaced by more expensive closer generation to reduce the exceeded power flows. In a congested area, the optimal price of electricity rises to the marginal cost of the local generation or to the level needed to ration demand to the amount of available electricity. Even without congestion, some power will be lost in the transmission system through heat dissipation, so prices reflect that it is more expensive to supply electricity at the far end of a heavily loaded line than close to an electric power generation. Locational marginal pricing (LMP), resulting from bidding competition, represents electrical and economical values at nodes or in areas that may provide economical indicator signals to the market agents. This article proposes a data-mining-based methodology that helps characterize zonal prices in real power transmission networks. To test our methodology, we used an LMP database from the California Independent System Operator for 2009 to identify economical zones. (CAISO is a nonprofit public benefit corporation charged with operating the majority of California’s high-voltage wholesale power grid.) To group the buses into typical classes that represent a set of buses with the approximate LMP value, we used two-step and k-means clustering algorithms. By analyzing the various LMP components, our goal was to extract knowledge to support the ISO in investment and network-expansion planning.

RSE, Développement durable et gouvernance d’entreprise Un jeu d’acteurs et de structures... ad hominem ou ad libitum du marché ?

Prenant l’illustration des États-Unis, la responsabilité sociale des entreprises et le développement durable intègrent progressivement le droit des sociétés. Si ce mouvement s’inscrit dans le sens de l’histoire, il a pris depuis quelques temps une intensité particulière. D’une part, la gouvernance d’entreprise montre des signes de remise en question du dogme de la primauté des actionnaires comme en témoigne la jurisprudence rendue à propos des devoirs des administrateurs et des dirigeants. D’autre part, les structures sociétaires récemment mises en place dans plusieurs État américains (Benefit Corporation et Flexible Purpose Corporation) constitue une étape fondamentale pour une contribution de nature différente du monde économique à la société lato sensu. Néanmoins, les conséquences de ces mutations demeurent à l’heure actuelle difficiles à évaluer tant elles font face à des obstacles dont le droit américain des sociétés est lui-même porteur.

Image and imaging an emergency department: expense and benefit of different quality assessment methods

Introduction. In this era of high-tech medicine, it is becoming increasingly important to assess patient satisfaction. There are several methods to do so, but these differ greatly in terms of cost, time, and labour and external validity. The aim of this study is to describe and compare the structure and implementation of different methods to assess the satisfaction of patients in an emergency department. Methods. The structure and implementation of the different methods to assess patient satisfaction were evaluated on the basis of a 90-minute standardised interview. Results. We identified a total of six different methods in six different hospitals. The average number of patients assessed was 5012, with a range from 230 (M5) to 20 000 patients (M2). In four methods (M1, M3, M5, and M6), the questionnaire was composed by a specialised external institute. In two methods, the questionnaire was created by the hospital itself (M2, M4).The median response rate was 58.4% (range 9-97.8%). With a reminder, the response rate increased by 60% (M3). Conclusion. The ideal method to assess patient satisfaction in the emergency department setting is to use a patient-based, in-emergency department-based assessment of patient satisfaction, planned and guided by expert personnel.

Short nomenclator or vocabular in English and Hebrew: composed alphabetically for the use and benefit of my pupils in particular and for the advantage of those who are desirous to obtain the knowledge of the Hebrew tongue in general, which may be that great help to understand not only ye sacred oracles in their original, but even any Jewish author (so far as concern owns) as also it may give great insight in ye tongue to those, as to compose it, a work altogether new, [ca. 1735]

Headed on the first page with the words "Nomenclatura hebraica," this handwritten volume is a vocabulary with the Hebrew word in the left column, and the English translation on the right. While the book is arranged in sections by letter, individual entries do not appear in strict alphabetical order. The small vocabulary varies greatly and includes entries like enigma, excommunication, and martyr, as well as cucumber and maggot. There are translations of the astrological signs at the end of the volume.

S Corporations Can Benefit Many Closely-Held Hospitality Firms

In his discussion - S Corporations Can Benefit Many Closely-Held Hospitality Firms - by John M. Tarras, Assistant Professor, School of Hotel, Restaurant & Institutional Management at Michigan State University, Assistant Professor Tarras initially offers: “Organization as an S corporation has many advantages for hospitality firms since passage of the Tax Reform Act of 1986. The author discusses those advantages and lists the disadvantages as well.” In the opening paragraphs Tarras alludes to the relationship between hospitality firms, S corporations, and the Tax Reform Act of 1986, and then defines what an S corporation is. “An S corporation is a form of business entity that combines many of the tax advantages of partnerships with the legal attributes of a corporation, including limited liability for its shareholders. Its name is obtained from a subchapter of the Internal Revenue Code. Except for tax purposes, the S corporation is treated in the same manner as any regular corporation. Like a partnership, income and losses for an S corporation are generally passed through directly to shareholders for inclusion on their individual returns. An S corporation thus avoids the double tax problem facing regular corporations.” There are certain criteria to be met and caveats to be avoided in qualifying for S corporation status. Tarras lists and cites these for you. “Due to the complicated nature of S corporations, the election may be inadvertently terminated if the eligibility requirements are violated,” Tarras expands and cites. As the article suggests at the outset, there are advantages and disadvantages to S corporation status; the author outlines some examples for you. “Traditionally, the S corporation has been used by hospitality firms wishing to avoid the "double tax" problem of a regular corporation,” Tarras informs you. “Regular corporations are taxed once at the corporate level, and again at the shareholder level when income is distributed to shareholders in the form of dividends.” Tarras advises you as to why an S corporation is an advantage in this situation. “Since the S corporation generally is not subject to any corporate taxes, it generally makes no difference whether distributions to shareholders of S corporations are characterized as compensation or dividends,” thus the double tax is avoided. This is just one such positive illustration. Assistant Professor Tarras wants you to know: “Perhaps the most important reason to consider the S corporation has to do with the downward revision of tax rates for both individuals and corporations.” He highlights a case study for you. Some of the disadvantages of S corporation affiliation are the caveats alluded to earlier. They include, “the limitation of an S corporation of 35 shareholders,” Tarras cites. “Also, there are limits as to who may own stock in an S corporation.” These are but two of the limitations of an S corporation. Tarras closes with a further glimpse of the down-sides of an S corporation.

Using performance measurement models for benefit realization with enterprise systems: The Queensland Government approach (Case Study)

A range of influences, technical and organizational, has encouraged the wide spread adaption of Enterprise Systems (ES). Nevertheless, there is a growing consensus that Enterprise Systems have in the many cases failed to provide the expected benefits to organizations. This paper presents ongoing research, which analyzes the benefits realization approach of the Queensland Government. This approach applies a modified Balance Scorecard. First, history and background of Queensland Government’s Enterprise Systems initiative is introduced. Second, the most common reasons for ES under performance are related. Third, relevant performance measurement models and the Balanced Scorecard in particular are discussed. Finally, the Queensland Government initiative is evaluated in light of this overview of current work in the area. In the current and future work, the authors aim to use their active involvement in Queensland Government’s benefits realization initiative for an Action Research based project investigating the appropriateness of the Balanced Scorecard for the purposes of Enterprise Systems benefits realization.
