    Norms and normative multiagent systems have become the subjects of interest for many researchers. Such interest is caused by the need for agents to exploit the norms in enhancing their performance in a community. The term norm is used to characterize the behaviours of community members. The concept of normative multiagent systems is used to facilitate collaboration and coordination among social groups of agents. Many researches have been conducted on norms that investigate the fundamental concepts, definitions, classification, and types of norms and normative multiagent systems including normative architectures and normative processes. However, very few researches have been found to comprehensively study and analyze the literature in advancing the current state of norms and normative multiagent systems. Consequently, this paper attempts to present the current state of research on norms and normative multiagent systems and propose a norm's life cycle model based on the review of the literature. Subsequently, this paper highlights the significant areas for future work.

    Full Text Available Background. The balance error scoring system (BESS is a brief, easily administered test of static balance. The purpose of this study is to develop normative data for this test. Study Design. Cross-sectional, descriptive, and cohort design. Methods. The sample was drawn from a population of clients taking part in a comprehensive preventive health screen at a multidisciplinary healthcare center. Community-dwelling adults aged 20–69 (N=1,236 were administered the BESS within the context of a fitness evaluation. They did not have significant medical, neurological, or lower extremity problems that might have an adverse effect on balance. Results. There was a significant positive correlation between BESS scores and age (r=.34. BESS performance was similar for participants between the ages of 20 and 49 and significantly declined between ages 50 and 69. Men performed slightly better than women on the BESS. Women who were overweight performed significantly more poorly on the test compared to women who were not overweight (P<.0001; Cohen's d=.62. The BESS normative data are stratified by age and sex. Conclusions. These normative data provide a frame of reference for interpreting BESS performance in adults who sustain traumatic brain injuries and adults with diverse neurological or vestibular problems.

    Memory and attention are two cognitive domains pivotal for the performance of instrumental activities of daily living (IADLs). The assessment of these functions is still widely carried out with pencil-and-paper tests, which lack ecological validity. The evaluation of cognitive and memory functions while the patients are performing IADLs should contribute to the ecological validity of the evaluation process. The objective of this study is to establish normative data from virtual reality (VR) IADLs designed to activate memory and attention functions. A total of 243 non-clinical participants carried out a paper-and-pencil Mini-Mental State Examination (MMSE) and performed 3 VR activities: art gallery visual matching task, supermarket shopping task, and memory fruit matching game. The data (execution time and errors, and money spent in the case of the supermarket activity) was automatically generated from the app. Outcomes were computed using non-parametric statistics, due to non-normality of distributions. Age, academic qualifications, and computer experience all had significant effects on most measures. Normative values for different levels of these measures were defined. Age, academic qualifications, and computer experience should be taken into account while using our VR-based platform for cognitive assessment purposes. ©Pedro Gamito, Diogo Morais, Jorge Oliveira, Paulo Ferreira Lopes, Luís Felipe Picareli, Marcelo Matias, Sara Correia, Rodrigo Brito.

    The integration of the first Aeolian farm of large scale (La Venta II) to the National Interconnected System requires taking into account the random and discontinuous nature of the Aeolian energy. An important tool, for this task, is a system for the prognosis of the Aeolian energy in the short term. For this reason, the Instituto of Investigaciones Electricas (IIE) developed a statistical model to realize this prognosis. The prediction is done through an adaptable linear combination of alternative competing models, where the weights given to each model are based on its more recent prognosis quality. Also, the application results of the prognoses system are presented and analyzed. [Spanish] La integracion de la primera grana eolica de gran escala (La Venta II) al Sistema Interconectado Nacional requiere tomar en cuenta la naturaleza aleatoria y discontinua de la energia eolica.

Por ello, el Instituto de Investigaciones Electricas (IIE) desarrollo un modelo estadistico para realizar este pronostico. La prediccion es hecha a traves de una combinacion lineal adaptable de modelos competidores alternativos, donde los pesos dados a cada modelo estan basados en su mas reciente calidad de pronostico. Tambien se presentan y analizan los resultados de la aplicacion del sistema de pronosticos.

    CERN Document Server

    Garcia, Emilia; Botti, Vicente

    2015-01-01

    Addressing the open problem of engineering normative open systems using the multi-agent paradigm, normative open systems are explained as systems in which heterogeneous and autonomous entities and institutions coexist in a complex social and legal framework that can evolve to address the different and often conflicting objectives of the many stakeholders involved. Presenting  a software engineering approach which covers both the analysis and design of these kinds of systems, and which deals with the open issues in the area, ROMAS (Regulated Open Multi-Agent Systems) defines a specific multi-agent architecture, meta-model, methodology and CASE tool. This CASE tool is based on Model-Driven technology and integrates the graphical design with the formal verification of some properties of these systems by means of model checking techniques. Utilizing tables to enhance reader insights into the most important requirements for designing normative open multi-agent systems, the book also provides a detailed and easy t...

    This commentary addresses some of the challenges posed by the broader normative, legal and policy framework of the United Nations for the international drug control system. The 'purposes and principles' of the United Nations are presented and set against the threat based rhetoric of the drug control system and the negative consequences of that system. Some of the challenges posed by human rights law and norms to the international drug control system are also described, and the need for an impact assessment of the current system alongside alternative policy options is highlighted as a necessary consequence of these analyses.

    The electrical energy is an essential element in the activities of the present world. Optimizing its consumption represents a competitive advantage for the companies, since the operation costs would be reduced as well as the negative impact to the environment. In billing the electrical energy the tariffs consider: the consumption, the demand, the power and the schedule of use for the medium and large companies. With the Opti-dmaX system the necessary information for the correct administration of the electrical energy consumption is obtained from the measurement in the strategic points of the installation. At the same time, the processes and services are controlled, maintaining an efficient power operation that diminishes operative costs. [Spanish] La energia electrica es un elemento indispensable en las actividades del mundo actual, y optimizar su consumo, representa una ventaja competitiva para las empresas, ya que se consigue reducir los costos de operacion y el impacto al ambiente.

    2014-11-21

    Transsexual women who are on the journey of sexual re-alignment will experience various health problems. These problems are related directly to the treatment regime that they are following in order to attain and maintain their physical embodiment as a woman. They are forced to negotiate a hetero-normative healthcare system in order to receive assistance and care for their health problems related to their sexual re-alignment process. The questions posed were: What are the unique health problems that transsexual women experience whilst on the journey of sexual re-alignment? What is the current context of the South African healthcare system in which transsexual women should negotiate healthcare? These questions were asked in order to explore the health problems with which transsexual women are faced and to describe the hetero-normative healthcare system in South Africa. An electronic literature search was executed via the EBSCO host with specific inclusion and exclusion criteria. The search words that were used were: Transsexual/s and Health/Healthcare. All studies had to be peer reviewed and published in the English language, from January 1972 up until February 2013. Literature on transsexual children was excluded. Transsexual women have the potential to suffer significant side-effects from their sexual re-alignment treatment, including cardio-vascular problems, endocrine problems and mental ill-health. They are also vulnerable to HIV infection. They have poor access to quality holistic healthcare and this may lead an increase in the mortality and morbidity figures of women. A hetero-normative healthcare system has a negative impact on the health of transsexual women and will cause them to be marginalised. This could contribute to both homo- and trans-phobia that will in turn strengthen the belief that transsexual women are un-African.

    The serious challenge imposed by the necessity of reducing the gases emission of greenhouse effect in the electric generation sector, it has renovated the interest in the new plants construction of nuclear energy. Nevertheless, since the use of the nuclear energy began to descend ago more of 25 years, it is has speculated continually about the possible nuclear rebirth. Are such predictions based in solid basis or are mere groundless prognostics? The objective of the present document is to analyze the economic aspects of the nuclear energy, to identify the key factors that they allow to determine its competitiveness and to sound the possible markets for the new plants of nuclear energy. To achieve this, it is divided in the following sections: Revision of the current state of the nuclear energy, including the location, the type and capacity of the plants; Identification of the variables that determine the economic situation of the nuclear energy; Revision of the recent predictions and of the economic aspects of the Olkiluoto nuclear power plant of Finland; A revision by market of the possible future of the new nuclear facilities in the coming decade.

    Jaime Hoogesteger

    2015-03-01

    Full Text Available This paper analyzes conflict and collaboration and their relation to normative structures based on a case study of the history and external interventions of the Píllaro North Canal Irrigation System in the Ecuadorian Highlands. It does so by using Ostrom’s framework for analyzing the sustainability of socio-ecological systems together with an analysis of the normative structures that define the governance systems through which the interactions in irrigation systems are mediated. I argue that the external interventions by the state and NGOs imposed a new governance system that undermined the existing normative structures and related organizations, leading to internal conflicts. The case study suggests that a reformulation of irrigation policies and state intervention methodologies in user managed supra-community irrigation systems in the Andes could lead to higher levels of cooperation.

  4. Innovation Systems for Transformations towards Sustainability? Taking the Normative Dimension Seriously

    Directory of Open Access Journals (Sweden)

    Michael P. Schlaile

    2017-12-01

    Full Text Available The aim of this article is to complement research on transformations towards sustainability by drawing upon the innovation systems (IS framework. The IS framework already serves as a suitable and influential basis for research on processes of technological innovation and economic change. We argue that improving the capacity of an IS framework for dealing with wicked problems and the normative complexity of sustainability requires a fundamental paradigm shift because in the current IS paradigm innovations are considered as per se desirable and in mostly technological terms. Therefore, we call for IS dedicated to transformations towards sustainability by opening up for systemic innovations beyond the technological dimension and by acknowledging that stakeholders have conflicting visions, interests, norms, and expectations with regard to sustainability goals. Taking the normative dimension of transformations towards sustainability seriously thus requires more explicit and integrative research on directionality, legitimacy, responsibility, and their interrelation in IS. The article concludes by proposing suggestions for future research based on IS-related approaches that can serve as building blocks for an IS framework capable of incorporating legitimate goal-orientation for transformative innovation by and for society.

  10. The natural defense system and the normative self model [version 1; referees: 2 approved

    2016-05-01

    Full Text Available Infectious agents are not the only agressors, and the immune system is not the sole defender of the organism. In an enlarged perspective, the ‘normative self model’ postulates that a ‘natural defense system’ protects man and other complex organisms against the environmental and internal hazards of life, including infections and cancers. It involves multiple error detection and correction mechanisms that confer robustness to the body at all levels of its organization. According to the model, the self relies on a set of physiological norms, and NONself (meaning : Non Obedient to the Norms of the self is anything ‘off-norms’. The natural defense system comprises a set of ‘civil defenses’ (to which all cells in organs and tissues contribute, and a ‘professional army ‘, made of a smaller set of mobile cells. Mobile and non mobile cells differ in their tuning abilities. Tuning extends the recognition capabilities of NONself by the mobile cells, which increase their defensive function. To prevent them to drift, which would compromise self/NONself discrimination, the more plastic mobile cells need to periodically refer to the more stable non mobile cells to keep within physiological standards.

    The primary purpose of the present study was to establish a preliminary adult normative database for 41 phonatory aerodynamic measures obtained with the KayPENTAX Phonatory Aerodynamic System (PAS) Model 6600 (KayPENTAX Corp, Lincoln Park, NJ). A second purpose was to examine the effect of age and gender on these measures. Prospective data collection across groups. A sample of 157 normal speakers (68 males and 89 females) were divided into three age groups (18-39, 40-59, and 60+ years). The PAS protocols of vital capacity, maximum sustained phonation, comfortable sustained phonation, variation in sound pressure level, and voicing efficiency were used to collect 41 phonatory aerodynamic measures. Comfortable pitch and loudness levels were used with each protocol requiring phonation. A statistically significant main effect of age was found for seven measures, and a statistically significant main effect of gender was found for five measures. The remaining 29 measures did not reach statistical significance; however, 13 of these had high observed power. The remaining 16 measures did not reach significance and had low observed power. Because age- and gender-related changes were found for some measures, one must account for these two variables when assessing phonatory aerodynamics using the PAS Model 6600. The clinical implications of the findings for the assessment and treatment of individuals with voice disorders using the PAS Model 6600 are discussed. Copyright © 2012 The Voice Foundation.

  12. Considering the normative, systemic and procedural dimensions in indicator-based sustainability assessments in agriculture

    International Nuclear Information System (INIS)

    Binder, Claudia R.; Feola, Giuseppe; Steinberger, Julia K.

    2010-01-01

    This paper develops a framework for evaluating sustainability assessment methods by separately analyzing their normative, systemic and procedural dimensions as suggested by Wiek and Binder [Wiek, A, Binder, C. Solution spaces for decision-making - a sustainability assessment tool for city-regions. Environ Impact Asses Rev 2005, 25: 589-608.]. The framework is then used to characterize indicator-based sustainability assessment methods in agriculture. For a long time, sustainability assessment in agriculture has focused mostly on environmental and technical issues, thus neglecting the economic and, above all, the social aspects of sustainability, the multi-functionality of agriculture and the applicability of the results. In response to these shortcomings, several integrative sustainability assessment methods have been developed for the agricultural sector. This paper reviews seven of these that represent the diversity of tools developed in this area. The reviewed assessment methods can be categorized into three types: (i) top-down farm assessment methods; (ii) top-down regional assessment methods with some stakeholder participation; (iii) bottom-up, integrated participatory or transdisciplinary methods with stakeholder participation throughout the process. The results readily show the trade-offs encountered when selecting an assessment method. A clear, standardized, top-down procedure allows for potentially benchmarking and comparing results across regions and sites. However, this comes at the cost of system specificity. As the top-down methods often have low stakeholder involvement, the application and implementation of the results might be difficult. Our analysis suggests that to include the aspects mentioned above in agricultural sustainability assessment, the bottom-up, integrated participatory or transdisciplinary methods are the most suitable ones.

    In the Metropolitan Area of Mexico City, as well as in other regions with a similar climate, there are an important number of users of the electric energy service, whose main load consists of lighting, since systems such as environmental conditioning, refrigeration, pumping and others are either not necessary or lack of importance as electric energy consumers. These are classified in the range of small users that altogether represent a significant saving, but the precarious diffusion of the technological advances have not contemplated the need of carrying on corrective actions.

    Determination of electrical losses is one of the most important tasks for any enterprise dedicated to generation, transmission, transformation and/or distribution of electric energy. Any enterprise dedicated to these activities does continuously energy balances in order to estimate whole electrical losses of specific processes. However, it is necessary to classify the whole electrical losses into technical and non-technical losses. This paper presents a proposal for estimating technical and non-technical losses in an electrical power system. [Spanish] La determinacion de las perdidas de energia electrica es una de las labores mas importantes en cualquier empresa dedicada a la generacion, transmision, transformacion y/o distribucion de energia electrica. Es indudable que toda empresa dedicada a cualquiera de las actividades mencionadas anteriormente realiza periodicamente balances de energia que permiten estimar el valor de las perdidas totales de energia del proceso considerado. No obstante, para poder realizar un mejor analisis de la problematica de las perdidas de energia, es necesario separar el valor total de perdidas obtenido mediante un balance de energia, en perdidas tecnicas y perdidas no tecnicas. El presente trabajo presenta una propuesta para la estimacion de perdidas tecnicas y no tecnicas en un sistema electrico de potencia.

    Bregn, Kirsten; Jagd, Søren

    1992-01-01

    This paper explores the conditions for applying normative control in co-operatives. For normative control to be effective two conditions are found particularly important: Individuals must be morally involved and the organization must have a system of making it possible to link common norms...... and individual action. If these conditions are not fulfilled, as may be the case in many co-operatives, normative control cannot be expected to work. The problems of normative control in co-operatives may then not be caused by the use of normative control as such, but may instead be a problem of securing...

    Full Text Available Although energy analysis is a way to evaluate the sustainability of production systems, this practice is not often used in the agribusiness. In this context, the castor bean (Ricinus communis L is an agricultural crop not yet well studied despite its great potential in the Brazilian energetic scenario. This article aimed to evaluate the productive potential of the castor bean oil, using an energetic view applied to two management systems: low (System 1 and medium (System 2 technologies. The quantification of the used material fluxes was made converting these factors in energy units. The input energy fluxes were 3,170.6 MJ ha¹ and 10,366.0 MJ ha¹ for Systems 1 and 2, respectively. The energy balance of System 1 was 11,938.2 MJ ha¹ and that of System 2 16,296.5 MJ ha¹. The net energetic gain or the energy gain over the invested energy (EROI of System 1 was 3.8 and of System 2, 2.6. Although presenting a greater energy demand and a lower EROI, System 2 had a greater energy balance, demonstrating a better viability of this cultivation system for the production of castor bean oil.A análise energética é uma forma de se avaliar a sustentabilidade de um sistema produtivo, apesar de ainda pouco utilizada no setor agropecuário.

    algorithm in a digital program, this was proved in a personal computer applying it to IEEE transmission systems evaluated with other methods, among them one of 140 buses and 199 transmission lines. The results as far as reliability indexes compared with the other methods were very satisfactory and promising as far as required CPU time and memory for larger systems. [Spanish] En esta tesis se ataca el problema de la Evaluacion de la Confiabilidad de los Sistemas de Transmision de Energia Electrica para fines de su planeacion integral. Una vez descrito el problema se presentan los indices que miden la confiabilidad de los sistemas electricos de potencia. Despues se describen los metodos para evaluar las redes de transmision, como el de Enumeracion de Contingencias, el Monte Carlo, el de Markov y los metodos para sistemas complejos como el de Cortes Minimos. Este ultimo se desarrolla ampliamente por las ventajas que presenta su aplicacion en la planeacion de redes grandes y complejas. El metodo de cortes minimos consta de dos grandes pasos: Determinar los cortes minimos para los puntos de carga y calcular los indices de confiabilidad en base a los cortes minimos. Los algoritmos convencionales para la determinacion de cortes minimos consideran un problema por cada punto de carga en forma independiente pasando por una determinacion de caminos minimos. En este tipo de algoritmos el tiempo de CPU y el espacio en memoria requeridos crecen exponencialmente para el caso de sistemas de transmision grandes, lo que representa una fuerte restriccion para su aplicacion. Para resolver este problema se establecio una metodologia en la que se modela el sistema por medio de un grafo y se determinan los cortes minimos con un algoritmo basado en la construccion de ciclos en el grafo dual. Con estos cortes se evalua la conexidad y capacidad de la red, obteniendose los indices de confiabilidad para cada bus y para el sistema. Estos indices se calculan con la representacion equivalente para

    The objective of this dissertation is to accomplish an introduction to the studies and the applications of the System Protection Schemes (SPS) used to maintain the electric power systems safety. A small group of definitions and concepts from the 'protection, reliability and power systems performance analysis' areas is presented with the objective of distinguishing SPS from the conventional system component protections. It also helps in understanding the functions of the SPS with more clarity. The SPS are used to maintain the integrity of the system when it is submitted to phenomena that provoke instability or cascade circuit outages. The classification and the description of these phenomena, as well as the SPS application are shown in this dissertation. The general structure of the SPS, the ways of classifying them and the different actions used by SPS to control the disturbances are the objectives of the analysis of this work. In order to exemplify, a vision is given of how the SPS are located in the Brazilian interconnected system (BIS) and also in the rest of the world. Some SPS used in Brazil deserved special attention. The analyses of the main blackouts that occurred in Brazil and in North America are presented, in a summarized term, in appendix I. Considerable knowledge is obtained from these analyses, leading to implementation measures that minimize the risk of interruptions in the energy supply. A comparison is also made of the degree of severity of the great blackouts that happened in Brazil and, for the two largest, an estimate of their respective interruption costs is made. In appendix II, an attempt was also made to establish the basic requirements for the SPS implementation using micro processing technology. Based on the experience lived during the studies developed by the group that analyzed the safety of the Bis after the blackout on March 11/1999, criteria and procedures to analyze the safety of the system and to accomplish studies of SPS

    Although use of Electronic Nicotine Delivery Systems (ENDS) is increasingly prevalent among young adults, little is known about predictors of ENDS initiation among this population. We examined the roles of the social environment (i.e., peer ENDS use and household ENDS use), normative beliefs (i.e., social acceptability of ENDS use), and attitudes (i.e., inclination to date someone who uses ENDS) in prospectively predicting initiation of ENDS over a 1-year period among 18- to 29-year-old college students. Participants were 2,110 (18- to 29-year-old) students ( M = 20.27, SD = 2.17) from 24 colleges in Texas who participated in a three-wave online survey, with 6 months between each wave. All participants reported never using ENDS at baseline. A multivariable, multilevel logistic regression model, accounting for clustering of students within colleges, was used to assess if students' social environment, normative beliefs, and attitudes predicted subsequent initiation of ENDS up to 1 year later, adjusting for various sociodemographic factors and number of other tobacco products used. In all, 329 college students (16%) initiated ENDS within 1 year. Results from the logistic regression indicated that college students who were younger (18-24 years old), ever used other tobacco products, indicated a more dense peer network of ENDS users, and had a higher inclination to date someone who uses ENDS had higher odds of initiating ENDS than their peers. Preventing ENDS initiation should be included in college health promotion programs, which should highlight the roles of students' social environment and attitudes regarding ENDS use.

    Full Text Available The aim of the article is to study the normative legal regulation of accounting activities of non-bank financial institutions to ensure the strategic development of the financial system of Ukraine. There actualized the issue of examining the system of normative legal regulation in terms of: first, regulation of the market for non-bank financial services and their activities as an object of accounting; second, regulation of accounting and reporting as the basis of the impact on its organization, methodology; third, formation of requirements to the management of the institution concerning the qualification requirements to the chief accountant as a subject of organization and carrying out the accounting activities. In the course of the research, there developed a model for influencing the transformation of the organization and methodology of accounting, which will be implemented by establishing new requirements to its methods and objects as a result of changes in the normative legal acts and their impact on the systems of economic analysis and audit as components of corporate management of non-bank financial institutions. The proposed model determines the impact of the provisions of the integrated program for the development of the financial sector of Ukraine until 2020 in accounting in terms of methodology, specificity and composition of its objects. As a result of studying the set of documents that define the strategic provisions for the development of the market for non-bank financial services, there identified directions for the formation of new and transformation of the existing provisions of the normative legal regulation of the accounting system through its elements (methods, objects, subjects, study of its functions and justification of the significance in risk management. We believe that these provisions should be implemented by means of the development of organizational and methodological regulations for the accounting of non

    Kibrit, Eduardo

    2008-01-01

    The present work identifies, characterizes and analyses the normative requirements for the development and implementation of quality management systems in Brazilian nuclear installations and activities. The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

    The incorporation of computer aided teaching technologies increases the efficiency in the transmission and acquisition of knowledge, allowing the handling of large information volumes, the knowledge homogenization among the students, the availability, the massive teaching and the permanent updating of the same. On the other hand, considering that all energy saving policy must be supported in a training and dissemination program of the respective energy technologies an immediate option is the use of computerized systems of teaching-learning. Precisely, in this paper, are presented the fundamental technical aspects for the development of a tutorial expert system, to aid the training in energy cogeneration, trying to integrate in the application, the usage of multimedia tools with the intelligent handling of the teaching-learning process through the inference machine of an expert system.

    Full Text Available This paper aims to analyze the influence of Instruction 30 (IN30 which includes registration and labeling of food for pets, from the point of view of interpretation, assimilation and its possible impacts on agents that comprise the pet food Agribusiness System (SAG. Were interviewed institutions, represented by two major agencies: The Ministry of Agriculture, and Livestock (MAPA and the Brazilian Association of the Industry of Products for Pets (ABINPET; manufacturing firms; research centers based at Universities, retailers and owners of dogs and cats, totalizing five samples. It was observed that the institutions, the researchers and manufacturers consider the IN30 as an initiative of great importance by bringing self-control and self-regulation of the SAG, besides contemplating the desire of firms regarding agility in launching new technologies. However, the main concern of the researchers was related to quality assurance of food. Firms show up unssatisfied with the lack of consensus on the interpretation of some articles of IN30 by MAPA´s enforcement agents, with discrepancies between regional and the technical managers of companies, especially regarding labeling. Already retailers and owners of pets still seem unaware of the legal aspects of such normative.

    Fuel cells, as totally clean power plants, have many applications in the industry in general, in the transport system, in the electricity generation for domestic consumption and in the communication systems, among others. When developing new forms of generation with renewable energy sources, it must be considered that petroleum will stop in being an available power resource. The interest in the study of the fuel cells has been increased in the last years because it is considered a solution to the supply of distributed energy problem. Therefore, already exist research institutions that are developing work on this technology. A generation of electrical energy system based on fuel cells is a nonlinear system where the control of the variables of the process, such as the temperature of the system and the pressurization of the reactants, are an important aspect for its proper operation, since it influences in the water balance and therefore in the global efficiency of the system. [Spanish] Las celdas de combustible, como fuente de energia totalmente limpia, tienen muchas aplicaciones en la industria en general: en el sistema de transporte, en la generacion de electricidad para consumo domestico y en los sistemas de comunicacion, entre otros.

El interes en el estudio de las celdas de combustible se ha incrementado en los ultimos anos debido a que se le considera una solucion al problema de abasto de energia distribuida. Por lo tanto, ya existen instituciones de investigacion que estan desarrollando trabajos sobre esta tecnologia. Un sistema de generacion de energia electrica basado en celdas de combustible es un sistema no lineal en donde el control de las variables del proceso, tales como la temperatura del sistema y la presurizacion de los reactantes, es un aspecto importante para su buen funcionamiento, ya que

    Garcia, Emilia; Giret, Adriana; Botti, Vicente

    2016-03-01

    There is an increasing interest on developing virtual enterprises in order to deal with the globalisation of the economy, the rapid growth of information technologies and the increase of competitiveness. In this paper we deal with the development of normative open virtual enterprises (NOVEs). They are systems with a global objective that are composed of a set of heterogeneous entities and enterprises that exchange services following a specific normative context. In order to analyse and design systems of this kind the multi-agent paradigm seems suitable because it offers a specific solution for supporting the social and contractual relationships between enterprises and for formalising their business processes. This paper presents how the Regulated Open Multi-agent systems (ROMAS) methodology, an agent-oriented software methodology, can be used to analyse and design NOVEs. ROMAS offers a complete development process that allows identifying and formalising of the structure of NOVEs, their normative context and the interactions among their members. The use of ROMAS is exemplified by means of a case study that represents an automotive supply chain.

    This work aims at studying the results of an optimisation model applied to the Paranaiba river basin, Brazil. This system is made by the junction of three river branches located in a region with a well-defined seasonal hydrological behavior. The ratio between the total energy storage in the system and the active storage for every reservoir is evaluated from the optimal operational results. This relationship allows recognizing systematic patterns on the relative use for every reservoir, when compared to the entire system. The main parameters that define reservoir behavior are identified, with highlights on the position of the power station in the cascade, the relationship between the river flow and the active storage, and the installed capacity of the power station. In addition, the parameter hydrological scenario is also another factor that defines the relative use of the reservoirs. [Spanish] El modelo del presente trabajo tiene como objetivo estudiar los resultados de una optimizacion para el sistema hidroelectrico de la cuenca del rio Paranaiba, Brasil, la cual esta formada por la confluencia de tres rios en una region de distribucion de lluvias bien definidas en terminos hidrologicos. Se analiza la relacion entre la energia total almacenada en el sistema y el volumen util de cada embalse a partir de los resultados operativos optimos. Esta relacion permite identificar resultados sistematicos en lo que se refiere a la utilizacion de cada embalse, en comparacion con el uso del sistema como un todo. Se identifican los principales parametros responsables por el comportamiento de los embalses, destacando la influencia de la posicion de la central hidroelectrica en la cascada, de la relacion caudal/volumen util y de la potencia de central. Ademas, el parametro escenario hidrologico tambien es otro factor determinante en el uso relativo de los embalses.

[Spanish] Las baterias plomo-acido (BPA) son ampliamente utilizadas en la industria para almacenar energia quimica y liberarla en forma de electricidad. Los fenomenos que ocurren en el interior de una BPA -durante sus ciclos de carga y descarga - afectan la vida util de la bateria a largo plazo. En este sentido, se han realizado diversas investigaciones alrededor del mundo; no obstante, dichos estudios han arrojado solo dos conclusiones: a) La seleccion de un algoritmo de carga adecuado puede extender la vida util de la bateria. b) Un monitoreo continuo del banco puede ayudar a estimar el estado de salud de las baterias y a detectar los elementos del banco que estan mas proximos a fallar. Una bateria plomo-acido esta formada por un conjunto de celdas plomo-acido conectadas en serie. A mayor numero de celdas, mayor el voltaje de la bateria. Las BPA que se utilizan para formar bancos de respaldo de energia son dispositivos sumamente delicados cuya vida util depende fuertemente de factores como: temperatura de operacion, regimen de descarga, regimen de carga. Las BPA se conectan, en serie, para elevar el voltaje, o bien, en paralelo, para elevar la corriente suministrada por el banco. Con una combinacion de arreglos serie-paralelo es posible lograr casi cualquier especificacion de voltaje y corriente. Por otro lado, la operacion confiable de un arreglo de celdas requiere que todos los elementos de este funcionen correctamente. Si una celda falla en un arreglo serie, el resto deja de funcionar, lo que ocasiona costos de mantenimiento ademas de reducir la confiabilidad del sistema de respaldo. Para incrementar la confiabilidad de los arreglos de celdas Pb-A, es necesario un monitoreo individual y continuo de las celdas. Ello permite determinar cuales son las que tienen mayor probabilidad de falla y, entonces, poder reemplazarlas. Entre los principales beneficios de un sistema de monitoreo

    The present research investigated the persuasive impact and detectability of normative social influence. The first study surveyed 810 Californians about energy conservation and found that descriptive normative beliefs were more predictive of behavior than were other relevant beliefs, even though respondents rated such norms as least important in their conservation decisions. Study 2, a field experiment, showed that normative social influence produced the greatest change in behavior compared to information highlighting other reasons to conserve, even though respondents rated the normative information as least motivating. Results show that normative messages can be a powerful lever of persuasion but that their influence is underdetected.

In general terms, normative power is thought to be an ability or disposition, where A has normative power when it is able to diffuse through communicative acts a norm n to B. However, prevailing theories also assume that all uses of normative power are justified, and that this is dependent on the norm promoted being defined as valid. This alters the definition of normative...

    Full Text Available A conscientização da importância do meio ambiente tem incentivado o estudo de novas fontes energéticas renováveis e menos poluentes. Dentre essas fontes, a energia solar destaca-se por ser perene e limpa. A utilização da energia solar em sistemas de aquecimento de água residencial rural pode colaborar com a economia de energia elétrica, base da matriz energética brasileira. Conhecer os fatores que influenciam na operação de um sistema de aquecimento de água por energia solar é importante na determinação de sua viabilidade técnica, visando a sua difusão em residências rurais. Para tanto, construiu-se um protótipo, no câmpus da Faculdade Assis Gurgacz, em Cascavel - PR, com características similares a um equipamento utilizado em residências para dois habitantes, para funcionar com circulação natural ou termossifão e sem auxílio de sistema de aquecimento complementar. O equipamento mostrou-se viável tecnicamente, alcançando a temperatura mínima para banho de 35 °C, sempre que a radiação solar foi superior a 3.500 Wh m-2, o que aconteceu para a maioria dos dias estudados.The awareness of the importance of the environment has stimulated the study of new renewed energy sources and less pollutant. Amongst these sources, solar energy stands alone for being perennial and clean. The use of solar energy in systems of agricultural residential water heating, can complement the economy of electric energy, base of the Brazilian energy matrix. Knowing the factors that influence the operation of a system of water heating by solar energy is important in determining their technical viabilities targeting their distribution in agricultural residences.

    This work presents a comparative study among the direct solar energy utilization options ,through solar panels, coupled to the frequency inverter. These system store energy through batteries or through a reversible and hybrid solar/hydraulic system, coupled to a rectifier and a frequency inverter. There are two basic configurations for the systems being the first one composed of solar panels linked to a battery system , delivering electric energy through a three phase inverter. The second one is composed of solar panels connected to a small battery system and to a water reservoir that has the goal of operating as a reversible system during at night, or during load peak periods. In this ,it is presented a methodology for the designing and economic analysis, comparing this hybrid alternative, to the inverter plus batteries options. This methodology to the correct Energy Conversion System,which is economically advantageous due to the availability of the region. At the end, it is presented a 'case study' where viability of use , for the hybrid solar/hydraulic system in an isolated area, is verified. (author)

    The awareness of the importance of the environment has stimulated the study of new energy sources renewed and less pollutant. Amongst these sources, solar energy stands alone for being perennial and clean. The use of solar energy in systems of residential water heating, instead of the electric shower, can compliment the economy of electric energy, based on the Brazilian energy matrix. To know all the factors that influence the operation of a system of water heating by solar energy it is important the determination of its economic and technical viabilities and, distribution targeting in urban and agricultural residences. To evaluate equipment of water heating for solar energy in the region west of the Parana, Brazil, an archetype with similar characteristics to equipment used in residences for two inhabitants was built, to function with natural circulation or thermosyphon and without help of a complementary heating system. The room temperature and the speed of the wind were also evaluated, verifying its influence in the heating system. The equipment revealed technical viability, reaching the minimum temperature of 35 deg C for shower, whenever the solar radiation was above the 3500 W.m{sup -2}, for the majority of the studied days. The system operated without interruptions and it did not need maintenance, except for the monthly glass cleaning. Economic viability was clearly demonstrated since the useful life of the equipment exceeded the period of use to gain its investment. (author)

    Within the regional markets, as it is the case of MERCOSUR , the laboratories which are suppliers of test and calibration results, are mutually recognized through the National Accreditation Systems. In Argentina there is a project to create a Center for the Accreditation of Test Laboratories. CNEA, which is involved in the execution of large projects and has adopted quality assurance criteria for a long time, requires for internal and external laboratories to be qualified. At the beginning of this year, a Committee for the Qualification of Laboratories was created in the Research and Development and Fuel Cycle Areas. Its objective was planning, management of documents, coordination, evaluation and quantification of laboratories, according to national IRAM and international ISO standards. This paper analyzes the organization of the system and the methods to evaluate and qualify laboratories as a process of growing up leading to the future National Accreditation System.

    The International Atomic Energy Agency has developed the so-called International Project on Fuel Cycles and Innovative Nuclear Reactors (INPRO), in order to make nuclear energy available to meet the energy needs of the 21 century, in a sustainable way. One of the tasks of the project is the evaluation of the nuclear systems, to check whether they meet the objectives of the project and whether they are sustainable. This paper explains the rationale and general characteristics of the project in the evaluation of nuclear energy systems based on the concept of sustainable development. It describes the methodology developed to carry out this evaluation, divided into seven areas, such as economic, environmental, security, etc., which together make up the sustainable development of energy through nuclear systems. The economic area is analyzed and the evaluation criteria and parameters established by INPRO are discussed, in order to evaluate the Mexican nuclear energy system using Nest (software developed within the same project) as a tool to support the economic evaluation of nuclear systems. Based on the energy strategy proposed by the Energy Secretary of the Mexican Government which seeks to reduce the greenhouse gas emissions from the national electricity generation park, two types of reactor of currently available technology (A BWR and AP1000), were compared and these in turn with other alternative energy generation technologies, such as combined cycle, geothermal and wind plants. Also, the results of the application of the INPRO methodology are presented. Finally, the recommendations on actions that could lead the Mexican nuclear energy system towards sustainable development and conclusions on the application of the methodology to the Mexican case are mentioned.

    This work proposes an expert system integrated to procedures of numerical computation, denominated RD and projected to suggest alternatives of switching plans in the isolation and re-establishment of power distribution lines. The switching plans are based on the specialist's knowledge (network operator) and in evaluations of the electric conditions of the switching. Specialist's knowledge is represented in the form of triples (context, attribute, value) and production rules, that are evaluated conveniently by the machine of inference of the RD system. The electric power distribution is represented by a graph model, where the knots are load blocks and the arcs are key of the system. The evaluation of the electric requirements (voltage drop and physical capacity of the components of the power distribution lines) it is obtained through a maneuver simulator (numeric computation). The maneuver simulator bases on the Method of the Moments for the calculation of the voltage drop. With base in these ideas a prototype of the RD system was developed.

    One important historical challenge to the operation planning of the Brazilian interconnected electrical system has been the seasonal stabilization of the energy supply, due to the stochastic nature of hydro resources. Most of the significant Brazilian hydro power stations rely on the hydrological regimes of the Southeast, which have a remarkable tendency for seasonal fluctuations of significant amplitude. In the last decades, wind power generation has proven its suitability to the Gigawatt scale, necessary to an effective contribution to electric systems. This paper demonstrates, from existing data, the wind / hydro seasonal complementarity in the relevant areas of Brazil, and discusses its possible effect on the feasibility of seasonal stabilization of the energy supply in the Brazilian interconnected grid, taking advantage of the country's large natural resources available. Case studies for the southern/southeastern and the northeastern regions of Brazil are presented. (author)

    2007-07-01

    The possibility of storing energy is increasingly important and necessary. The reason is that storage modifies the basic equation of the energy production balance which states that the power produced should equal the power consumed. When there is a storage device in the grid, this equation is modified such that, in the new balance, the energy produced should equal the algebraic sum of the energy consumed and the energy stored (positive in storage phase and negative when released). This means that the generation profile can be uncoupled from the consumption profile, with the resulting improvement of efficiency. Even small-sized storage systems can be very effective.

    Objective of this research project is to examine effects of addition of nuclear capacity from three different angles by using energy system, electricity market and economic analysis. In each area the analysis is based on computational methods. Finland is a member of Nordic electricity market which is further connected to networks of Continental Europe and Russia. Due to the foreign connections Finland has been able to import inexpensive electricity from its neighboring countries and this state is expected to continue. Addition of nuclear capacity lowers electricity import demand, affects level of electricity price decreasingly and decreases shortfall of installed production capacity. Substantial additions of nuclear power capacity and generous import supply have disadvantageous effect on profitability of combined heat and power production. The development of import possibilities depends on progression of difficult-to-estimate balance between electricity consumption and production in the neighboring countries. Investments on nuclear power increase national product during the construction phase. Growth of employment is also rather significant, especially during the construction phase. In the long term permanent jobs will be created too. Increase of employment is held back by increasing real wages, but it is though evident that consumer purchasing power is improved due to these nuclear power developments. (orig.)

  5. Predictive analysis on the electric energy distribution systems reliability: applying the synerGEE system; Analisis predictivo de la confiabilidad en los sistemas de distribucion de energia electrica: aplicando el sistema synerGEE

    Electrical distribution systems ought to deliver electric power as economical as possible with an acceptable degree of service quality and continuity. Nevertheless, their faults represent one of the main causes of customer's unavailability. At the moment, a wide range of determinist criteria in the improvement of systems reliability based on past behavior are used, but they do not respond to the stochastic nature of system behavior, and are applied without an adequate balance between reliability and economy. In order to obtain this balance a minimum cost planning methodology that considers the predictive analysis of different investment alternatives in addition to the past behavior of the system is required, which guarantees that the economic resource available and limited will be used to gather the greater possible reliability degree. In this work this problem is approached with the fundamentals and methodologies needed to assess the design effects and operative criteria over the main reliability indexes used by the main utilities around the world, with emphasis on the need to optimize economical resources. The use of the system SynerGEETM, is investigated, probing it as a useful tool for the predictive reliability analysis. Due to the lack of experience that exists in Mexico with this type of analysis, distribution engineers has to become familiar with the concepts of the reliability engineering, their application to establish distribution systems models, and acquiring the ability to use the modern simulation tools, allowing them to evaluate the behavior of these systems with enough analytical rigor. In this sense a serial of well known study cases are presented to help them in this labor.

    The Clock Drawing Test (CDT) is a commonly used tool in clinical practice and research for cognitive screening among older adults. The main goal of the present study was to analyze the interrater reliability of three different CDT scoring systems (by Shulman et al., Babins et al., and Cohen et al.). We used a clock with a predrawn circle. The CDT was evaluated by three independent raters based on the normative data set of healthy older and very old adults and patients with nonamnestic mild cognitive impairment (naMCI; N = 438; aged 61-94). We confirmed a high interrater reliability measured by the intraclass correlation coefficients (ICCs): Shulman ICC = .809, Babins ICC = .894, and Cohen ICC = .862, all p < .001. We found that age and education levels have a significant effect on CDT performance, yet there was no influence of gender. Finally, the scoring systems differentiated between naMCI and age- and education-matched controls: Shulman's area under the receiver operating characteristic curve (AUC) = .84, Cohen AUC = .71, all p < .001; and a slightly lower discriminative ability was shown by Babins: AUC = .65, p = .012.

    The solar energy manifests itself in different forms and its application has been fundamental for the humankind development. These forms are known as renewable energies, since they are energy forms that are renewed or remade with time or that are so abundant on Earth, that they will last for hundreds or thousands of years, either we use them or not. The main advantage of the utilization of the renewable energies in comparison with hydrocarbons is the one of having smaller impact on the environment, which brings about the conservation of nonrenewable resources, and to postpone its exhaustion. They allow the distributed generation, diminishing the power losses in the transmission and distribution systems, which increases the overall efficiency. In addition they can be the drive for regional development and generation of employment, because when having applications in remote zones and being a field still not completely developed in Mexico, the possibility exists of enabling professionals and technicians. From the point of view of the power sector, the renewable energies extend the supply and availability of energy, making more flexible and independent the operation and reliability of the national power system. [Spanish] La energia solar se manifiesta de diversas formas y su aplicacion ha sido fundamental para el desarrollo de la humanidad. A estas formas se les conoce como energias renovables, ya que son formas de energia que se van renovando o rehaciendo con el tiempo o que son tan abundantes en la tierra, que perduraran por cientos o miles de anos, las usemos o no. La principal ventaja del aprovechamiento de las energias renovables en comparacion con los hidrocarburos es la de tener menor impacto al medio ambiente, lo que trae consigo la conservacion de recursos no renovables, y posponer su termino. Permiten la generacion distribuida, disminuyendo las perdidas energeticas en los sistemas de transmision y distribucion, lo que incrementa la eficiencia general. Ademas

  16. Hate crimes and normative regulation

    Directory of Open Access Journals (Sweden)

    Kovačević Milica

    2011-01-01

    Full Text Available This paper is primarily devoted to issues related to the normative regulation of hate crimes, with special reference to the regulations of the Republic of Serbia, which are indirectly related to this matter. This kind of crimes are characterized by prejudices that perpetrators have towards injured parties, as members of certain, mostly, minority groups, due to which many hate crimes could be also called crimes of prejudice. In comparative law there are two different basic directions when it comes to regulating hate crimes: separation of hate crimes in a separate category on the one hand, and punishment of perpetrators of criminal acts with the detriment of minority groups through the usual charges of a given criminal justice system, on the other. The author finds that, regardless of the formal response forms, real life suggests that hate crimes can be essentially suppressed only by promoting values such as equality, respect for diversity and tolerance, and by continuous education of public about the danger of hate crimes.

Using...... nutritional science as an example, we identify three such implicit normative issues. The first concerns the aim of scientific advice: whether it is about avoiding harm or promoting good. The second concerns the intended beneficiaries of the advice: whether advice should be framed to benefit the society...... as a whole or with special concern for the most vulnerable members of the population. The third consideration involves scientific advisers' attempts to balance the strengths of the scientific evidence with the expected consequences of scientific advice.

    A hybrid solar/diesel water heating system for therapy in a hospital in Mexico is described in this paper. The use of solar energy in hospitals and clinics, represent an environmentally friendly alternative to the burning of fossil fuels. Analysis is made regarding the feasibility of integrating both solar energy and conventional energy (fuel oil) as back up, to satisfy the hot water demand for hydrotherapy in a hospital. Results from simulation show that solar energy is a cheap means to provide up to 60% of the hot water demand. The solar assisted system proposed uses flat plate solar collectors integrated with an existing hot water tank, where water is heated with vapor from a diesel ran boiler. This represents significant savings on the solar system cost. [Spanish] La utilizacion de la energia solar en hospitales y clinicas, representa una posibilidad para obtener ahorros importantes de energia para satisfacer la demanda de agua caliente. En el presente estudio se analiza la demanda de agua caliente para uso en medicina fisica (hidroterapia), en un hospital ubicado en la Cd. De Mexico y la factibilidad de usar la energia solar, empleando como apoyo el sistema tradicional de combustible fosil (diesel). Mediante un analisis termico se determina el calor necesario para satisfacer la demanda de agua caliente. El analisis economico muestra los costos del sistema solar, los ahorros que se tendran y el periodo de recuperacion de la inversion. Los resultados muestran que la utilizacion de la energia solar es factible debido a la disminucion tanto del consumo de combustible, como de las emisiones atmosfericas. Se propone la instalacion de un sistema solar con colectores planos y el aprovechamiento de uno de los dos tanques de agua caliente existentes, donde se efectua la trasferencia de calor al agua por medio de vapor, lo cual disminuye el costo del sistema solar. La aportacion solar puede ser mayor del 60%, el complemento sera aportado por el sistema tradicional con

The net present value of the system is determined by consideration of all financial benefits and costs (including a specified return on investment). Life cycle costs, life cycle revenues, and residual system values are obtained. Break even values of system parameters are estimated by setting the net present value to zero. While the model was designed for photovoltaic generators with a possible thermal energy byproduct, it applicability is not limited to such systems. The resulting owner-dependent methodology for energy generation system assessment consists of a few equations that can be evaluated without the aid of a high-speed computer.

  14. Normative Judgments and Individual Essence.

    De Freitas, Julian; Tobia, Kevin P; Newman, George E; Knobe, Joshua

    2017-04-01

    A growing body of research has examined how people judge the persistence of identity over time-that is, how they decide that a particular individual is the same entity from one time to the next. While a great deal of progress has been made in understanding the types of features that people typically consider when making such judgments, to date, existing work has not explored how these judgments may be shaped by normative considerations. The present studies demonstrate that normative beliefs do appear to play an important role in people's beliefs about persistence. Specifically, people are more likely to judge that the identity of a given entity (e.g., a hypothetical nation) remains the same when its features improve (e.g., the nation becomes more egalitarian) than when its features deteriorate (e.g., the nation becomes more discriminatory). Study 1 provides a basic demonstration of this effect. Study 2 shows that this effect is moderated by individual differences in normative beliefs. Study 3 examines the underlying mechanism, which is the belief that, in general, various entities are essentially good. Study 4 directly manipulates beliefs about essence to show that the positivity bias regarding essences is causally responsible for the effect. Copyright © 2016 Cognitive Science Society, Inc.

    This is a report of an interview between the 'Energia Nucleara' reporter and Mr David S. Harris, the AECL project director for Cernavoda NPP Unit 2. The following items were addressed during the interview: the status of the Cernavoda NPP Unit 2 project; the differences in the project between Unit 1 and Unit 2; the Romanian infrastructure and industrial contributions to the Unit 2 project; the cooperation with Romanian design team; the Canadian authorities support to Unit 2 completion; Unit 3 project and AECL possible involvement. Following the Romanian Government's decision to complete Cernavoda Unit 2 in late 2002 work was recommenced in the key areas of engineering, procurement of equipment and materials signing of major supply contracts and construction, such that the total project is now 52% complete. actual construction activities are now 41% complete, and the number of key milestones have recently been achieved, such as: Closure of the Reactor Building 'B' Opening; commencement of rolling in of 45,000 main turbine condenser tubes; commencement of post-tensioning works on the Reactor Building structure and the completion of various infrastructure civil works. Structures and equipment already delivered, and installed or stored are in good conditions and ready for construction continuation. The following changes were implemented in Unit 2 as compared to Unit 1: design changes to meet new regulations and provide increases in the margin of safety; changes due to development of nuclear technology, particularly those improving performance and reliability of operation; design changes to replace equipment affected by obsolescence to allow purchasing of spare parts in the future. Concerning the future, AECL is willing to cooperate with the Romanian SNN on the Unit 3 completion process

    The process of technological development is due to the need to promote a solution to a particular problem of agents, compete with products and/or processes on the international market and to promote scientific advancement. Thus, the patent system is a repository of knowledge for protection, for promotion of diffusion through licensing agreements and an indicator of technological development. In 2004, the Brazilian Government enacted the Brazilian Innovation Act and the mechanisms were improved for cooperation between firms and public education, science and technology organisations and also promoted the commercialisation of technology produced by public education, science and technology organisations and the mandatory establishment of Technology Transfer Offices. The Comissao Nacional de Energia Nuclear (CNEN) is a federal agency responsible for basic and applied research in the field of nuclear technology and has used the patent system since the 1980s to protect its knowledge. With the advent of the Innovation Act in 2004, there was a significant boost in requests for patents in CNEN which also established an internal set of normative acts and created a System of Innovation Management and Technology Innovation Offices in its research institutes to support management and dissemination of knowledge. The aim of this case study is to present the profile of the requests for patents by CNEN before and after the enactment of the Brazilian Innovation Act covering the period of time between 1980 and 2010.

    Full Text Available Purpose: To explore financial alternatives to implement PV power generation projects based on the provisions of Normative Resolution n. 482/2012 of the Brazilian Electricity Regulatory Agency (Aneel. This regulation sets forth the general conditions to the access of micro- and minigeneration granted to the electric energy distribution systems through the energy product offset method. Originality/gap/relevance/implications: This paper discusses the need for regulatory changes, greater government participation in the granting of financial and tax incentives so that PV solar power technology in distributed generation can be financially viable for residential consumers. Key methodological aspects: Investment analysis in PV systems used the Net Present Value (NPV valuation method. The research assessed two scenarios for Grid-Connected PV Systems (GCPVSs, with different solar power usage levels for a residential consumer. Summary of key results: The results point to a low financial viability in the implementation of distributed microgeneration projects, suggesting the need to remove the tax burden and reduce financing costs. Key considerations/conclusions: The study shows the need of flexibilization of the Brazilian regulatory model, with changes that enable the expansion of renewable energy offers, with positive economic outcomes for tariff affordability. Tariff benefits from distributed microgeneration can positively reflect on captive customers, provided that investment risks are reduced.

    On a naturalistic conception of agency, someone is an agent when certain of his own mental states are the cause of his movements. On a normative conception, a person constitutes his agency by following certain principles or laws. In Kant’s conception, for example, a movement counts as the agent’s own when it is chosen autonomously, that is, in accordance with the categorical imperative. To say that someone acts is to imply that his movements are a manifestation of his own activity and that it...

  1. When is normative recruitment legitimate?

    Full Text Available Rosamond Rhodes and John Harris have both recently argued that we all have a general moral duty to participate in medical research. However, neither Rhodes' nor Harris' arguments in support of this obligation stand up to scrutiny, and severe and convincing criticism has been levelled against their case. Still, to refute their arguments is not to refute the conclusion. There seems to be some truth in the view that when people are asked to take part in medical research, their choice is not completely morally neutral. In this article, we argue that the proper question to ask is when, rather than if, a certain moral duty to volunteer for medical research can be appealed to. To answer this question, we need a denser description of relevant research projects and their context rather than just describing medical research in general. Drawing on our study of participants in the Norwegian HUNT biobank, we use the normative implications of the Norwegian concept «dugnad» as an analogy to discuss the requirement of providing neutral information to potential biobank participants in order to promote their free and informed decision as to whether or not to take part. We suggest that normative recruitment is not just a question of principles and ethics. It is also a question of research design and the creation of the common good in the community where the research takes place.http://dx.doi.org/10.5324/eip.v2i2.1697

    Buildings use a large amount of energy to operate and are one of the main sources of contaminating emissions. A building is a complex system and all of their components contribute to the total energy demand. The technology to construct zero-energy buildings is already available, but obstacles exist such as the lack of information and technical training of architects and engineers to design highly energy efficient buildings. The present article describes the progress to-date and the future prospects for the design and construction of zero-energy buildings, as well as the problems involved in its implementation. [Spanish] Los edificios usan una gran cantidad de energia para operar y son una de las principales fuentes de emisiones contaminantes.

El presente articulo muestra los avances a la fecha y la prospectiva para el diseno y construccion de edificios de energia cero, asi como la problematica para su implementacion.

  8. The Normative Orientations of Climate Scientists.

    Science.gov (United States)

    Bray, Dennis; von Storch, Hans

    2017-10-01

    In 1942 Robert K. Merton tried to demonstrate the structure of the normative system of science by specifying the norms that characterized it. The norms were assigned the abbreviation CUDOs: Communism, Universalism, Disinterestedness, and Organized skepticism. Using the results of an on-line survey of climate scientists concerning the norms of science, this paper explores the climate scientists' subscription to these norms. The data suggests that while Merton's CUDOs remain the overall guiding moral principles, they are not fully endorsed or present in the conduct of climate scientists: there is a tendency to withhold results until publication, there is the intention of maintaining property rights, there is external influence defining research and the tendency to assign the significance of authored work according to the status of the author rather than content of the paper. These are contrary to the norms of science as proposed by Robert K. Merton.

    This work describes a model capable of including non-conventional energy sources into a stochastic energy production model for conventional power sources. A wind energy system is initially considered as statistically independent of the hourly demand. The correlation between two wind systems is then considered by means of a joint wind speed distribution. The joint wind system is thereafter submitted to the stochastic energy production model considering independence between demand and wind speed. Finally the correlation wind systems and the hourly demand is studied. (author). 29 figs, 31 tabs

    corn production systems. The experimental delineating was in casual blocks with arrangement in subdivided parcels, with the production systems as main parcels and the cultivate crops as sub parcels. The seeding was accomplished directly in oat and azevem straws. In the chemical system the vegetable covering was wiped with glyphosate (2 L/ha), while in the organic system it was used roll machinery to handle the straw. All the inputs, in products or operations form, and the outputs, in grain form, were transformed in energy to estimate the energy balance. The energy coefficients were obtained in research travails. The employed energy was divided in three categories, according to its origin, as biological, fossil and industrial. In the category of biological energy the items human work, seeds, bio fertilizer and humus were inserted. The oil products and by-products, such as chemical fertilizer, pesticides, diesel were grouped in fossil energy category. Industrial energy was considered one that was used in the manufacture of machinery used in the products process. Are included in this categories: tractor and tools. The energy consumption in the organic corn production system was of 2,047.42 MJ ha{sup -1} and the energy conversion was of 78,235.33 MJ ha{sup -1}, and the biological energy was the energy form more consumed, 65,77% of total consumed, while in the conventional system the consumption was of 3,764.66 MJ ha{sup -1} and the energy conversion of 82,653.29 MJ ha{sup -1}, and the fossil was energy form more consumed, representing 79.57% of the energy consumed in this production system. The organic production system presented an efficiency of 38.21 significantly larger than the chemical system with 21.95. (author)

    The purpose of this study was to assess the energy flux and energetic balance related to the swine production and the recycling of residues generated by the system for utilization as organic fertilizers. The experiment was carried out at Vale dos Ipes Farm, located in the city of Ouro Verde do Oeste, in the Western of Parana State. One finishing phase swine unity containing 600 animals was monitored from January to June 2005. The treatment system is composed by one steel digester with capacity for 50 m{sup 3}, one sedimentation tank, one algae tank and one bio fertilizer storage tank. The swine barn cleaning is performed by dry scratching on a daily basis. The generated residues flow by gravitation through ducts towards the digester. The duration of the hydraulic retention period was 12 days. In the calculation of energetic efficiency, the energetic component ration is the greatest energetic cost in production system of finishing phase swine, corresponding to 95% from the total direct energy. At the way out of the energy system, the energetic component of swine for slaughtering corresponds to 56.8%. The system fitted into the features of an industrial agroecosystem, importing the majority of the consumed energy in the productive process and exporting more than 56% of the production as swine for slaughtering, while the remaining is used in the property as fertilizer.

    Hashimoto, Kleber

    1997-07-01

    The aim of operation planning of electrical energy distribution systems is to define a group of interventions in the distribution network in a way to reach a global optimization. Both normal operation and emergency conditions are considered including scheduled interventions in the network. Under normal conditions, some aspects as voltage drop and loss minimization, for example, are considered; under emergency conditions, the minimization of non-distributed energy and interruption time are taken into account. This proposes the development of a computer environment for operation planning studies. The design and implementation of a specific operation planning database, based on a relational database model, was carried out so that new information modules could be easily included. A statistical approach has been applied to the load model including consumption habits and seasonal information, for each consumer category. A group of operation planning functions is proposed, which includes simulation modules responsible for system analysis. These functions and the database should be designed together. The developed computer environment allows the inclusion of new functions, due to the standardized query language used to access the database. Two functions have been implemented for illustration. The development of the proposed environment constitutes a step towards an open operation planning system, an integration with other information systems and an easy-to-use system based on graphical interface.

    This paper presents the application and use of a methodology based on fuzzy theory and simulates its use in intelligent control of a hybrid system for generating electricity, using solar energy, photovoltaic and wind. When using a fuzzy control system, it reached the point of maximum generation of energy, thus shifting all energy generated from the alternative sources-solar photovoltaic and wind, cargo and / or batteries when its use not immediately. The model uses three variables used for entry, which are: wind speed, solar radiation and loading the bank of batteries. For output variable has to choose which of the batteries of the battery bank is charged. For the simulations of this work is used MATLAB software. In this environment mathematical computational are analyzed and simulated all mathematical modeling, rules and other variables in the system described fuzzy. This model can be used in a system of control of hybrid systems for generating energy, providing the best use of energy sources, sun and wind, so we can extract the maximum energy possible these alternative sources without any prejudice to the environment.

    Heating piglets in nursery and farrowing may be improved to save energy, without affecting the animals' welfare. The objective of this research was to compare the electrical energy use and thermal environment promoted by three heating technologies for piglets in nursery. The heating technologies studied were: suspended electrical resistors, heated floor and convection heating. Electrical energy consumption (kWh), maximum power demand requirements (kW), specific consumption (kWh/kg of produced live body weight), efficiency of heating system (deg C /m{sup 3} air) and dry-bulb temperature (deg C) and temperature-humidity index were evaluated. The heated floor system was better under the aspect of electrical energy use. The electrical resistance heating system was the best regarding to the animals' thermal comfort needs. (author)

    Due to the recent Brazilian electricity crisis, the advantages of the centralized rain dependent generation were put under discussion. The co-generation is an option for the consumer that does not want to be harmed by eventual interruptions in the energy supply and nor to pay higher tariffs during pick load. Besides, the excess of co-generation can be sold for the distribution companies, making possible that the independent producer has profits participating of the electricity power market. The distributed generation provides several benefits, for the fact of being a generation that is located close to the load. Besides, it allows the supply of the growing demand in a fast way, since the construction of big hydroelectric plants, that is the generation model more used in Brazil, is a slow process. With that, the insertion of distributed generation in the Brazilian system tends to become every more common year to year, as it has been happening in other countries. It is noticed, however, that few technical studies on the impacts of the distributed generation in the distribution systems were accomplished to the moment. Problems as over-voltages during light load, impacts on the protection system, and dynamic stability problems, very common in large centralized synchronous machines, can also start to happen in the distribution systems. This article presents a preliminary study on the influence of distributed synchronous generators in the operation of a distribution system. The analyzed technical aspects are: voltage profile, voltage stability, active and reactive power losses, and also critical clearing times for eliminating faults considering different sceneries. The simulations results show which are the main operative restrictions for maximizing the penetration level of distributed generation related with the dynamic and steady-state performance of the electricity distribution system.

    Electric energy is an essential component of economical integration of the regions of a country. The operation of an isolated electric system do not admit the adequate rearrangement of the energy flux, mainly in the rush time, which takes to deficit situations in some economical sectors, accentuated by generation options that are not totally compatible with the local reality. This work performs an comparison on the various electric generation options in isolated systems, specially in the Amazon region, based on their local characteristics and generation costs, according to the existent data obtained in the literature or from the electric generation companies.

    Despite of the rising in the fuel and its by-products, alternative energy sources have not vet developed specially in small plants for local generation. Thermal solar energy and biomass could provide most of the thermal energy required in the residential and commercial buildings and provide new solutions such as solar cooling, but people usually distrust because of its difficulties to be operated by no expert staff. In this situation remote operation systems are necessary to increase the number of installations and increase the sales. In the same way these kinds of systems could increase the technology exports to development countries where alternative energy sources can provide energy generation solutions that would improve the quality of life.

    One of the main difficulties to people who live in remote areas or isolated community and not grid connected, certainly is to access potable drink water. In the world, more than 6000 children dies everyday by some kind of illnesses associated to non-potable drink water. At state of Ceara, during the dry weather periods, remain water reservoir becomes practically a mud puddle, as a result, people and animals are forced to drink this inappropriate water. To minimize this consequences in this periods some water is distributed by tankers but, sometimes, even this water is not enough potable. Underground water is an alternative to mitigate this problem. The most common technique is the use of direct current (DC) pumps set supplied by solar photovoltaic systems. However, this kind of pump-set is relatively expensive and too hard to maintain. This paper brings an alternative lower expensive and sustainable to water pumping system, it uses a three phase induction machine coupled to an underwater centrifugal pump supplied by solar photovoltaic energy system.

    Dispatchable renewable power generation is usually associated with expensive storages or additional back-up systems. Solar-hybrid systems can combine solar energy with an additional fuel and thus reliably provide electric power. If renewable fuels (e.g., biofuels) are employed, power generation becomes 100% sustainable at zero net emissions. Systems based on gas turbines are suited for cogeneration or combined cycles, making them very efficient and cost effective. These cycles require high temperatures and pressures, thus the solar energy has to be concentrated by a heliostat field onto the top of a tower and transferred by a solar receiver into the gas turbine cycle. At smaller power levels, cogeneration of heat and power is an attractive option by making use of the high exhaust temperature of the gas turbine, thus getting an additional benefit. The aim of this proposal is an significant extension of the objectives of the recently started SOLHYCO project by means A profound knowledge for market introduction will be gained by the assessment of the Brazilian market concerning solar resources, biofuels, electricity markets, heat markets and social needs. A detailed design study for a first demonstration unit will deliver all necessary economical, social and environmental data and accordingly 3 case studies have been defined. (author)

    The awareness of the importance of the environment has stimulated the study of new renewed energy sources and less pollutant. Amongst these sources, solar energy stands alone for being perennial and clean. The use of solar energy in systems of agricultural residential water heating, can complement the economy of electric energy, base of the Brazilian energy matrix. Knowing the factors that influence the operation of a system of water heating by solar energy is important in determining their technical viabilities targeting their distribution in agricultural residences. To evaluate equipment of water heating for solar energy, a prototype was constructed in the campus of Assis Gurgacz College, in Cascavel,State of Parana, Brazil, with similar characteristics to equipment used in residences for two inhabitants, to function with natural circulation or thermo siphon and without help of a complementary heating system. The equipment revealed technical viability, reaching the minimum temperature for shower, of 35 deg C, whenever the solar radiation was above the 3,500 Wh m{sup -2}, for the majority of the studied days.

    Soer R, van der Schans CP, Geertzen JH, Groothoff JW, Brouwer S, Dijkstra PU, Reneman MF. Normative values for a functional capacity evaluation. To establish normative values for a functional capacity evaluation (FCE) of healthy working subjects. Descriptive. Rehabilitation center. Healthy working subjects (N=701; 448 men, 253 women) between 20 and 60 years of age, working in more than 180 occupations. Subjects performed a 2-hour FCE consisting of 12 work-related tests. Subjects were classified into categories based on physical demands according to the Dictionary of Occupational Titles. Means, ranges, SDs, and percentiles were provided for normative values of FCE, and a regression analysis for outcome of the 12 tests was performed. Normative FCE values were established for 4 physical demand categories. The normative values enable comparison of patients' performances to these values. If a patient's performance exceeds the lowest scores in his/her corresponding demand category, then the patient's capacity is very likely to be sufficient to meet the workload. Further, clinicians can make more precise return-to-work recommendations and set goals for rehabilitation programs. A comparison of the normative values can be useful to the fields of rehabilitation, occupational, and insurance medicine. Further research is needed to test the validity of the normative values with respect to workplace assessments and return-to-work recommendations.

  19. Integrated empirical ethics: loss of normativity?

    van der Scheer, Lieke; Widdershoven, Guy

    2004-01-01

    An important discussion in contemporary ethics concerns the relevance of empirical research for ethics. Specifically, two crucial questions pertain, respectively, to the possibility of inferring normative statements from descriptive statements, and to the danger of a loss of normativity if normative statements should be based on empirical research. Here we take part in the debate and defend integrated empirical ethical research: research in which normative guidelines are established on the basis of empirical research and in which the guidelines are empirically evaluated by focusing on observable consequences. We argue that in our concrete example normative statements are not derived from descriptive statements, but are developed within a process of reflection and dialogue that goes on within a specific praxis. Moreover, we show that the distinction in experience between the desirable and the undesirable precludes relativism. The normative guidelines so developed are both critical and normative: they help in choosing the right action and in evaluating that action. Finally, following Aristotle, we plead for a return to the view that morality and ethics are inherently related to one another, and for an acknowledgment of the fact that moral judgments have their origin in experience which is always related to historical and cultural circumstances.

    This paper studies the efficiency of a fined tube solar collector used in artificial satellites and the relation of this efficiency with the entropy generation in the fin. The mathematical modeling of heat transfer in the collector leads to a non-linear integrodifferential system of equations, which is solved numerically. The solution gives the efficiency, which is presented as function of geometrical and physical characteristics of the collector. It is also shown that a minimum entropy generation in the fins, in a collector, whose characteristics are subjected to constraints, corresponds to an optimum efficiency, that is, an efficiency value advantageous to collector performance.

    2003-01-01

    Full Text Available Prior research has presented the moderating role of normative evaluations in the relationship between the impulsive buying trait and consumers’ buying behaviors. In this article the authors show that consumer tendency to buy something spontaneous, unreflectively and immediately can be perceived as a factor which describes buying impulsiveness. This article also shows conceptual and empirical evidence that there is some support for the moderating role of normative evaluations in the relationship between buying impulsiveness and impulse buying behaviors. Significance occurs when consumers believe that act on impulse is suitable. The result suggests that consumers’ normative evaluation can moderate the link between the trait and behavioral aspects of impulse buying.

    Medium and large size isolated systems with a significant contribution from renewable energy sources, specifically eolic energy, are not conveniently operated at the present, neither by the conventional ways of unit commitment/load dispatcher nor by the simplified procedures used in the small isolated power networks. This paper presents a new approaching, in the CARE framework which is financially supported by the European Union through the EEN-JOULE assistance program. The principal idea is to perform unit commitment on-line in the same dispatching cycle, by using the load forecasting and the more recent wind power. The process includes dynamic safety fast evaluation and a module for helping the decision making.

    The wireless mesh network communication technology, based on the IEEE802.11 standard, has been a relevant technology solution for wireless networking in the recent years. However, even with the elimination of cables for data communication, the wireless mesh networks have to be connected to a voltage source using an electrical cable that may not be available at the local installation. In this scenario, being Brazil a country located in a tropical zone that receives large annual solar irradiation, the conversion of photons to electricity can be an alternative to eliminate the needs of wiring to the mesh access points. This work contributes to the development of autonomous wireless mesh communication systems powered by solar energy, with easy installation in urban or rural areas. This work also describes its evaluations in aspects such as autonomy, wireless coverage, number of users supported, installation height and throughput. (author)

  10. Normative Virtue Theory in Theological Ethics

    Directory of Open Access Journals (Sweden)

    Nicholas Austin

    2017-09-01

    Full Text Available What place is there for virtue theory in theological ethics? Many question the normative significance of virtue theory in theological ethics today, leaving it to rule-based ethics to provide action-guidance. There are three key objections to the normativity of virtue theory: that virtue theory is about agents rather than actions, that virtue theory has nothing to say directly about the morality of actions, and that the virtues are too vague to be of normative or action-guiding significance. This essay, drawing on Thomas Aquinas’s account of virtue, challenges these perceptions and argues for a genuinely normative, action-guiding virtue theory within theological ethics. Theological ethics, in turn, can contribute to virtue theory, especially by its emphasis on the ecstatic nature of mature moral virtue, and through its reflection on the virtue of spiritual discernment.

    The technological advances generate far reaching changes in all types of installation. The new spaces and the existing ones justify the introduction of new technologies taking into account important economic considerations, mostly when the advantage of daylight is taken into consideration in industrial and commercial lighting. In the daylight design it is necessary to know the solar transit, the atmospheric conditions, the architectural design of the building, the materials and the control elements, etc. to apply with precision the calculation method.

    The technological advances generate far reaching changes in all types of installation. The new spaces and the existing ones justify the introduction of new technologies taking into account important economic considerations, mostly when the advantage of daylight is taken into consideration in industrial and commercial lighting. In the daylight design it is necessary to know the solar transit, the atmospheric conditions, the architectural design of the building, the materials and the control elements, etc. to apply with precision the calculation method.

    2018-04-01

    Only a few years after the implementation of the G-DRG (German Diagnosis Related Group) system physicians already began to complain of its negative effects on the quality of inpatient healthcare. The present study examines the recent experiences senior physicians have made with regard to the impact of the G-DRG system on the quality of healthcare and medical professionalism. Nine qualitative guided expert interviews were conducted focusing on the experiences of physicians in leading positions dealing with the G-DRG system in their everyday work. The interviewees report an intensification of work attributable to an increasing number of inpatient cases, a more lenient definition of medical indications and a reduction in patient retention time. The physicians interviewed have felt increasingly constrained by economic conditions. Additionally, they stated that the G-DRG system's incentive structure encourages the discrimination of older, care-dependent and multimorbid patients. Possible countermeasures include a political revision of incentive regulation as well as a strengthening of up-to-date professional ethical education and teaching. Copyright © 2018.

  17. Cockpit task management: A preliminary, normative theory

    Science.gov (United States)

    Funk, Ken

    1991-01-01

    Cockpit task management (CTM) involves the initiation, monitoring, prioritizing, and allocation of resources to concurrent tasks as well as termination of multiple concurrent tasks. As aircrews have more tasks to attend to due to reduced crew sizes and the increased complexity of aircraft and the air transportation system, CTM will become a more critical factor in aviation safety. It is clear that many aviation accidents and incidents can be satisfactorily explained in terms of CTM errors, and it is likely that more accidents induced by poor CTM practice will occur in the future unless the issue is properly addressed. The first step in understanding and facilitating CTM behavior was the development of a preliminary, normative theory of CTM which identifies several important CTM functions. From this theory, some requirements for pilot-vehicle interfaces were developed which are believed to facilitate CTM. A prototype PVI was developed which improves CTM performance and currently, a research program is under way that is aimed at developing a better understanding of CTM and facilitating CTM performance through better equipment and procedures.

  18. Standards of Ombudsman Assessment: A New Normative Concept?

    Directory of Open Access Journals (Sweden)

    Milan Remac

    2013-07-01

    Full Text Available Today, an ombudsman is a traditional component of democratic legal systems. Generally, reports of the ombudsman are not legally binding. Due to this fact, the ombudsman can rely only on his own persuasiveness, on his acceptance by individuals and state institutions, on the understanding of the administration and on the accessibility and transparency of rules that underpin his reports. During investigations, ombudsmen assess whether the administration has acted in accordance with certain legal or extra-legal standards. Depending on the legal system, ombudsmen can investigate whether there is an instance of maladministration in the activities of administrative bodies, whether the administration has acted ‘properly’, whether it has acted in accordance with the law, whether administrative actions have breached the human rights of complainants or whether the actions of the administration were in accordance with anti-corruption rules etc. Regardless of the legislative standard of an ombudsman’s control, the ombudsman should consider and assess the situation described in complaints against certain criteria or against certain normative standards. A distinct set of standards which ombudsmen use during their investigation, or at least a clear statement of their assessment criteria, can increase the transparency of their procedures and the persuasiveness of their reports. Are the normative standards used by different ombudsmen the same? Do they possibly create a new normative concept? And can it possibly lead to a higher acceptance of their reports by the administration?

    2017-01-01

    The IT security law forced the energy industry to implement system certifications for the first time in history. In contrast to most companies in the energy industry, which often only knew about product certifications, the energy industry now has to enter new territory. Certification companies receive their legitimation in Germany through DAkkS. The DAkkS is embedded in the context of European Union law. The work of the certification companies is determined by the specifications of the DAkkS as well as by the requirements of the ISO/IEC standards. These regulations should in any case be known to a certification customer so that he knows what a certification company does or does not do. In addition, a certification customer must also know which evidence must be presented in the sense of a reference standard against the certification company. The concrete evidence in this essay is based on an ISO/IEC 27001 certification in conjunction with the IT Security Catalog of the Bundesnetzagentur. With all this knowledge, the cooperation with the certification company will not be a problem for system certification.

    The geologic history of the quartz normative (QNB) and olivine normative (ONB) basalt types at Hadley Rille are discussed. A model for the geology of the mare basalts was constructed from a combination of field observations, sample chemistry, sample petrology and personal bias from terrestrial experience. The model proposes that the QNBs are the only mare lava type that is present as outcrop in the area traversed by the astronauts during the Apollo 15 mission. The returned QNB samples formed during a single eruptive phase of the Hadley Rille lava tube system. The ONB lavas are an exotic component transported to the site by a cratering event, or the ONBs are samples excavated from older are bedrock that was partly covered by the QNB lavas

    We examined normative beliefs about multiple sexual partners and social status in China and their association with risky sexual behaviors and sexually transmitted infections (STIs). Self-reported and biological markers of sexual risk were examined among 3,716 market vendors from a city in eastern China. Men who were older or with less education believed having multiple sexual partners was linked to higher social status. Adjusting for demographic characteristics, normative beliefs were significantly associated with having multiple sexual partners, while having multiple sexual partners was significantly associated with STIs. Normative beliefs regarding sexual behaviors may play an important role in individual risk behaviors. Future HIV/STI interventions must address community beliefs about the positive meaning of sexual risks, particularly among men with traditional beliefs about gender roles.

    A review is made of the energy resources in use existing at the moment for the electricity production (hydraulic, coal, oil, gas and uranium). The asymptotic energies (solar, geothermal and nuclear fission and fusion) are described and the state of development in which they are up to the moment. One concludes that in the case of Mexico it would be convenient to make flexible and to reinforce the electrical systems in forecast of a greater participation of the distributed generation and to orient the extensions of the electrical generation to make a greater use of the three asymptotic energies already used: the solar (in its forms hydraulic and wind power), geothermal and the nuclear fission. [Spanish] Se pasa revista a los recursos existentes en las energias actualmente en uso para la produccion de electricidad (hidraulica, carbon, petroleo, gas y uranio). Se describen las energias asintoticas (solar, geotermia y fision y fusion nucleares) y el estado de desarrollo en que se encuentran hasta el momento. Se concluye que en el caso de Mexico convendria flexibilizar y reforzar el sistema electrico en prevision de una mayor participacion de la generacion distribuida y orientar las ampliaciones de la generacion electrica para hacer un mayor uso de tres de las energias asintoticas ya utilizadas: la solar (en sus formas hidraulica y eolica), la geotermia y la fision nuclear.

  7. Morality, Normativity, and Economic Development in Slovakia

    Directory of Open Access Journals (Sweden)

    David Karjanen

    2015-07-01

    Full Text Available This article examines debates over local economic development policies and practices in contemporary Slovakia, particularly regarding property and land development. Debates about economic development often occur in relation to economic outcomes, driven by quantitative data and empirical assessments provided by city officials or consultants. In this article, I find that such debates are more likely to be driven by normative concerns, including moral outcomes. I develop a theoretical framework to understand why policy debates occur not in purely objective terms, but the more subjective normative and moral frameworks. The analysis provides greater insight into political debates and policymaking in the postsocialist context.

    The domestic sector consumes almost one quarter of the national electrical energy. In order to reduce in an important manner the power consumption in dwellings there is an integral alternative based on three elements: the bio-climatic design, the saving and efficient use of the energy in equipment and apparatuses, and the use of centralized air conditioning systems. Besides saving the electrical and thermal power consumption, with this scheme, comfort conditions are pretended to be reached in dwellings and, contributing at the same time, to the diminution of polluting emissions. [Spanish] El sector domestico consume casi una cuarta parte de la energia electrica nacional. Con objeto de reducir de manera importante el consumo de energia en las viviendas, se presenta una alternativa integral, basada en tres elementos: el diseno bioclimatico, el ahorro y uso eficiente de la energia en equipos y aparatos, y la utilizacion de sistemas de climatizacion centralizados. Ademas del ahorro en el consumo de energia electrica y termica, con este esquema se pretende alcanzar condiciones de confort en las viviendas y, al mismo tiempo, contribuir a la disminucion de emisiones contaminantes.

  10. On the Normative Function of Metatheoretical Endeavors

    Directory of Open Access Journals (Sweden)

    Zachary Stein

    2010-07-01

    Full Text Available I reconstruct an historical understanding of metatheory that emphasizes its normative function. The pioneering work of James Mark Baldwin inspires an account of how metatheoretical constructs emerge developmentally and come to serve a discourse-regulative function—overseeing, organizing, and regulating whole fields of discourse. Then I look to Charles S. Peirce as an exemplary normatively oriented metatheorist and explain how both continue a philosophical tradition concerned with the normative function of humanity more broadly. Thus, while I think it is valuable to pursue a variety of metatheoretical endeavors, including descriptive and empirical ones—mapping the terrain of various discourses, or summarizing their contributions—I argue for a specific vision of metatheory as a normative endeavor with rich intellectual and historical precedence. Unpacking some of the implications involved with this way of viewing and doing metatheory lead to considerations about the differences between two general types of metatheory (scholastic-reductionist and cosmopolitan-comprehensivist, the role of philosophical interlocutors in the public-sphere, and the trajectory of human evolution in the coming decades.

    Zanotti, Renzo; Chiffi, Daniele

    2016-03-01

    This study addresses the question of normative analysis of the value-based aspects of nursing. In our perspective, values in science may be distinguished into (i) epistemic when related to the goals of truth and objectivity and (ii) non-epistemic when related to social, cultural or political aspects. Furthermore, values can be called constitutive when necessary for a scientific enterprise, or contextual when contingently associated with science. Analysis of the roles of the various forms of values and models of knowledge translation provides the ground to understand the specific role of values in nursing. A conceptual framework has been built to classify some of the classical perspectives on nursing knowledge and to examine the relationships between values and different forms of knowledge in nursing. It follows that adopting a normative perspective in the analysis of nursing knowledge provides key elements to identify its proper dimension. © 2015 John Wiley & Sons Ltd.

  1. Naturalism, Normativity, and the Study of Religion

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available This article repudiates the common view that the study of religion, in order to qualify as academic, must be descriptively neutral and naturalistic rather than normative or prescriptive. Following philosophers like John McDowell, John Cottingham, and Tyler Roberts, I claim that such a methodological stance amounts to viewing humans as determined rather than free agents. On the basis of W.V.O. Quine and Donald Davidson’s analysis of translation, I argue that normativity is ineliminable from humanistic scholarship, which is itself inextricable from religious studies. Robert Pippin and Thomas A. Lewis’s readings of Hegel then provide resources to reconcile human freedom and constraint in religion.

    Psychologists practicing in Canada must decide which set of normative data to use for the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). The purpose of this study was to compare the interpretive effects of applying American versus Canadian normative systems in a sample of 432 Canadian postsecondary-level students who were administered the WAIS-IV as part of an evaluation for a learning disability, attention-deficit hyperactivity disorder, or other mental health problems. Employing the Canadian normative system yielded IQ, Index, and subtest scores that were systematically lower than those obtained using the American norms. Furthermore, the percentage agreement in normative classifications, defined as American and Canadian index scores within five points or within the same classification range, was between 49% and 76%. Substantial differences are present between the American and Canadian WAIS-IV norms. Clinicians should consider carefully the implications regarding which normative system is most appropriate for specific types of evaluations. © The Author 2014. Published by Oxford University Press.

In the same way, in Chapter 4 a methodology for the optimization of the electrical grids in low tension is proposed, standing out some errors that are commonly committed in the design of these types of networks, doing recommendations to correct them with low cost investments. Because of the importance in the design of medium tension lines, in Chapter 3 the set of economic conductors for 23 kV was determined for urban and rural areas, system type A (3F-4H, 2F-3H, 1F-2H), by means of the Modified Method. With this information we will be able to select the conductor that offers the best economy in the time, in each extension of the network. In Chapter 5 the proposed methodology in the planning of the electrical system of distribution of the Zapotlan Zone was applied, as much in substations as in the high and medium tension network. In this chapter analyses of optimization of the network were performed, capacitor banks application, attention to the incremental demand, power losses, contingencies by fault and reliability of the provision. Finally the obtained conclusions of the investigation and the work carried out are presented; as well as the recommendations for future facilities.

    Full Text Available Um sistema híbrido é aquele que utiliza conjuntamente mais de uma fonte de energia para geração de energia elétrica, sendo que tal opção é feita de modo que uma fonte complemente a eventual falta da outra. Tais sistemas podem ser combinações de uma ou mais formas de geração, podendo ser usados sistemas eólicos, fotovoltaicos, diesel, hídricos, ou outros, sendo a opção do armazenamento energético não obrigatória. Dentre as fontes energéticas utilizadas pelos sistemas híbridos, as que mais se sobressaem são a solar e a eólica, ambas de caráter renovável. O sucesso de sua implantação depende diretamente da confiabilidade da operação ao fornecimento de energia e do custo da energia gerada. O objetivo deste trabalho foi apresentar diversas características de tais sistemas de geração de energia elétrica. Em relação ao dimensionamento do sistema, mostrou-se que é importante a análise de custos e formas de utilização do sistema, bem como fatores elétricos do sistema, tais como perda de carga e vida útil da bateria. Como forma de divulgação e especificação dos componentes de um sistema híbrido de geração de energia elétrica, foi eleito um sistema eólico fotovoltaico localizado na Faculdade de Ciências Agronômicas de Botucatu, o qual possibilitou diversas pesquisas junto ao Núcleo de Energias Alternativas e Renováveis do Laboratório de Energização Rural do Departamento de Engenharia Rural da UNESP, Faculdade Ciências Agronômicas, Campus de Botucatu.

This study addresses this gap by developing normative standards of the Rorschach method (Parisian School for this age group, evaluating specificities of production associated with sex, age and school system. The Rorschach tests were individually administered to 180 students aged from 15 to 17 years old, with typical signs of development. Data considering the 54 Rorschach's variables were descriptively and inferentially examined. The main average results were: (a productivity: R = 17.7; (b modes of apperception: G = 35.0%, D = 33.4%, Dd = 30.3% and Dd = 1.1%; (c determinants and formal indexes: F% = 54.5%, F+% = 55.6% and F+ext% = 57.3%; (d predominant content: A% = 51.0% and H% = 20.9%; (e Ban = 17.0%. Specificities of production according to sex, age and school system were identified, which supports the analysis and interpretation of Rorschach's variables with contemporary Brazilian adolescents.

  17. A design process for using normative models in shared decision making: a case study in the context of prenatal testing.

    Rapaport, Sivan; Leshno, Moshe; Fink, Lior

    2014-12-01

    Shared decision making (SDM) encourages the patient to play a more active role in the process of medical consultation and its primary objective is to find the best treatment for a specific patient. Recent findings, however, show that patient preferences cannot be easily or accurately judged on the basis of communicative exchange during routine office visits, even for patients who seek to expand their role in medical decision making (MDM). The objective of this study is to improve the quality of patient-physician communication by developing a novel design process for SDM and then demonstrating, through a case study, the applicability of this process in enabling the use of a normative model for a specific medical situation. Our design process goes through the following stages: definition of medical situation and decision problem, development/identification of normative model, adaptation of normative model, empirical analysis and development of decision support systems (DSS) tools that facilitate the SDM process in the specific medical situation. This study demonstrates the applicability of the process through the implementation of the general normative theory of MDM under uncertainty for the medical-financial dilemma of choosing a physician to perform amniocentesis. The use of normative models in SDM raises several issues, such as the goal of the normative model, the relation between the goals of prediction and recommendation, and the general question of whether it is valid to use a normative model for people who do not behave according to the model's assumptions. © 2012 John Wiley & Sons Ltd.

    The work developed a methodology fuzzy and simulated its use in control of a hybrid system of electric power generation, using solar-photovoltaic and wind energy. Using this control system, we get the point of maximum energy generation and transfer all the energy generated from alternative sources, solar-photovoltaic and wind energy to charge and / or batteries. The model uses three input variables, which are: wind (wind speed), sun (solar radiation) and batteries (charge the battery bank). With these variables, the fuzzy system will play, according to the rules to be described, what is the source of power supply system, which will have priority and how the batteries are loaded. For the simulations regarding the use of fuzzy theory to control, we used the scientific computing environment MATLAB. In this environment have been analyzed and simulated all mathematical modeling, rules and other variables described in the fuzzy system. This model can be applied to implement a control system of hybrid power generation, providing the best use of renewable energy, solar and wind, so that we can extract the maximum possible energy of these alternative sources without compromising the environment.

    Full Text Available The hyper-competitive nature of e-business has raised the need for a generic way to appraise the merit of a developed business strategy. Although progress has been made in the domain of strategy evaluation, the established literature differs over the ‘tests’ that a strategy must pass to be considered well-constructed. This paper therefore investigates the existing strategy-evaluation literature to propose a more integrated and comprehensive normative strategic assessment that can be used to evaluate and refine a business’ s competitive strategy , adding to its robustness and survivability.

  2. Normative framework for the protection against genetic discrimination in Serbia

    Directory of Open Access Journals (Sweden)

    Petrušić Nevena

    2015-01-01

    Full Text Available The paper is devoted to a normative framework of protection against genetic discrimination in the legal system of the Republic of Serbia, contained in the Law on Patients Rights, as of 2013 and in the Law on Prevention and diagnostics of genetic disorders, genetically conditioned anomalies and rare diseases, as of 2015. The analysis has shown that the rules on protection of the genetic data and the use of genetic samples, which are crucially important for prevention of genetic discrimination, have not been harmonized with contemporary ethical and legal standards. The contents of the Article 9 of the Law on Prevention and diagnostics of genetic disorders, genetically conditioned anomalies and rare diseases reduces the scope and level of protection against genetic discrimination in relation to the protection, given by the General Antidiscrimination Law. The legal definition of the genetic discrimination notion is not comprehensive, clear or precise, either, so it causes confusions, which, additionally, make the application of anti-discrimination regulations more difficult. Having in mind the harmful effects caused by the genetic discrimination, there is a need to eliminate the observed normative failures in due time and enable people to enjoy the benefits, provided by genetic investigations, without the fear from discrimination. In order to prevent the genetic discrimination, it is necessary to work on both information providing and raising awareness about the genetic privacy and the genetic discrimination problem, but also on promotion of the social justice and development of sensibility for bioethical challenges brought by the new age.

  3. International biomedical law in search for its normative status.

    Krajewska, Atina

    2012-01-01

    The broad and multifaceted problem of global health law and global health governance has been attracting increasing attention in the last few decades. The global community has failed to establish international legal regime that deals comprehensively with the 'technological revolution'. The latter has posed complex questions to regions of the world with widely differing cultural perspectives. At the same time, an increasing number of governmental and non-state actors have become significantly involved in the sector. They use legal, political, and other forms of decision-making that result in regulatory instruments of contrasting normative status. Law created in this heterogeneous environment has been said to be fragmented, inconsistent, and exacerbating uncertainties. Therefore, claims have been made that a centralised and institutionalised system would help address the problems of transparency, legitimacy and efficiency. Nevertheless, little scholarly consideration is paid to the normative status of international biomedical law. This paper explores whether formalisation and "constitutionalisation" of biomedical law are indeed inevitable for its establishment as a separate regulatory regime. It does so by analysing the proliferation of biomedical law in light of two the theory of fragmentation and the theory of global legal pluralism. Investigating the problem in this way helps determine the theoretical framework and methodology of future studies of biomedical law at the international level. This in turn should help its future development in a more consistent and harmonised manner.

  4. How Oedipus falsifies Popper: psychoanalysis as a normative science.

    Science.gov (United States)

    Wax, M L

    1983-05-01

    The scientific status of psychoanalysis has been the subject of continual debate. Influential philosophers of science have challenged the form of its theories and the nature of the evidence offered on their behalf. Some have concluded that the theories are beyond testing--i.e., they can neither be confirmed nor refuted, and psychoanalysis is thus intrinsically unscientific, akin to pseudosciences such as astrology. From that body of criticism, I have chosen for examination and rebuttal the issue of falsifiability. I refute the charge that psychoanalysis is not scientific because its theories are not "falsifiable." On the contrary, I show that psychoanalysis contains theories which make strong and unequivocal statements that are subject to the test of possible falsification. This capacity has been concealed and the falsifiability criticism rendered plausible because of the normative judgments which are latent in discussions of human development and human society. In explicating these judgments, I will move from the philosophy of science to the anthropology and sociology of science (and of the professions). The normative character of psychoanalytic science reinforces the ethical code of the therapeutic profession, a combination which imposes a disciplinary rigidity of the theoretical system.

    Helsinki Energia has started a new business activity - district cooling. The service is offered to cooling of large buildings, e.g. shopping centers, offices, etc. District cooling power is generated centrally at the power plant and the cooling power is transferred to the customer via separated distribution network. There are three main alternatives for production of district cooling power, mainly compressors, absorption devices and heat pumps. The operating energies required by them include electric power, district heat, steam, burning matter or some waste heat. The conditions for profitable district cooling are that the buildings to be cooled are built on a compact area at a reasonable distance from the district cool generation plant, that there enough need for district cool at the area, and that the district cool production plant is located at the seaside. Technically and economically reasonable construction of district cooling network requires that both the transmissions and distribution networks are as short as possible because the pipe dimensions are large, and because the streets are full of other infrastructure. Location near a sea ease the cooling of the district cool generation process, and especially, it is possible to use the coldness of the seawater directly via heat exchangers. The objective of district cool generation is to intensify the combined heat and power generation during warm seasons by reducing the electric power consumption and by increasing the utilization of surplus heat. It is also possible to reduce the use of harmful refrigerants. The district cooling activities of Helsinki Energia started in 1998 in Pitaejaenmaeki. Ruoholahti district cool system is the first larger area district cool project in Finland. The district cooling plant is constructed at the area of the Salmisaari power plant, hence the plant can utilize the present space and equipment of the power plant in generation of district cool.

    2015-03-01

    Full Text Available Academics studying genocide are required, amid the exigency of predicting and preventing further instances of this crime, to extend their efforts so as to connect with policy makers, provide vital information, respond to particular instances of genocide or state-inspired genocidal campaigns, and prompt a political will to intervene at any stage in this crime. May starts by placing genocide studies in the normative foundation of this discipline. In this work, which stands as the fourth volume of a broader project that assesses the “conceptual and normative underpinnings of this ‘crime of crimes’”, genocide is treated as the most serious of all international crimes. May calls for additional work to be performed to include other forms and conceptualizations of genocide such as cultural genocide and ethnic cleansing. The book outlines the fundamental concepts behind the crime, its study, and the discipline, while offering a unique presentation of “special problems of genocide”. It also considers steps that should be taken forward with the view of facilitating reconciliation. May refers to war as the final response to genocidal situations, not the first, stating that, “there are situations where there is not unambiguous groups of victims”. Thus, humanitarian intervention, as a viable approach to mitigating acts of genocide, is still difficult to justify.

However, there is a concern about the inertial Brazilian scenario, based on an increasing share of fossil fuels in the matrix, in prioritizing resources to oil and gas exploration and in the continuing unsustainable patterns of production and consumption.

    This presentation is mainly focused on all the projects carried out in order to boost renewable energies. Such projects have not only good results for the environmental sphere but also for the economic one. In the first part, there are found the general targets, which are going to foster the use of these sort of energies. Then, there are shown different kinds of photovoltaic systems. The implementation of these systems have a double target: to improve both activities: stock breeding and agriculture, and to foster the use of renewable energy. Next, there are mentioned the project investors. Similarly, there are described some of the components that are part of such projects along with their corresponding results. Finally, it is given a succinctly explanation about the conclusions as well as the future plans. [Spanish] Esta presentacion principalmente se enfoca en todos los proyectos que se han realizado para el fomento de las energias renovables, teniendo un impacto no solo ambiental sino tambien economico. En la primera parte, se encuentran los objetivos generales que se tienen para fomentar el uso de este tipo de energia.

    The subject of energy generation from garbage is discussed. A description is made of the sanitary fill, which is a system for the conversion or stabilization of garbage encompassing gas generation and lixiviates, these are collected to be used as fuels or a treatment process is applied to them avoiding this way the soil, water and air pollution; also a description is made of the utilization of a biogas recovery well, which recovers the biogas, cleans it from particles and condensates and afterwards feeds an internal combustion motor coupled to an electric generator. It is concluded that if the biogas generated by the buried garbage in the sanitary refills is utilized, the effects that cause the polluting emissions would be diminished and at the same time an additional energy resource would be on hand [Espanol] Se analiza el caso de la generacion de energia a partir de la basura. Se describe la tecnologia de relleno sanitario, la cual es un sistema de conversion o estabilizacion de la basura en el que existe generacion de biogas y lixiviados, estos se capturan para usarlos como combustibles o se les da un proceso de tratamiento y asi se evita la contaminacion del suelo, agua y aire; tambien se describe la utilizacion de un pozo de recuperacion de biogas, el cual recupera el biogas, lo limpia de particulas y condensados y despues alimenta a un motor de combustion interna acoplado a un generador. Se concluye en que si se aprovecha el biogas generado por la basura enterrada en rellenos sanitarios se diminuiran los efectos que causan las emisiones contaminantes y al mismo tiempo se tendria un recurso energetico adicional

    2009-01-01

    International standard ISO 10012:2003 establishes requirements for measurement management systems, including requirements for measurement processes and measuring equipment. ISO 9001:2008 presents requirements for quality management systems, including requirements for the control of monitoring and measuring equipment. ISO 17025:2005 presents general requirements for the competence of testing and calibration laboratories. In the nuclear field the requirements for measurement management are established by standards published by the International Atomic Energy Agency (IAEA), and in Brazil, by the National Nuclear Energy Commission (CNEN). The present paper presents and discusses the normative requirements for measurement management, considering requirements established by National Nuclear Energy Commission (CNEN), International Atomic Energy Agency (IAEA), and International Organisation for Standardisation (ISO).

    The European Union's foreign policy has traditionally been described in terms of national, supranational or transnational interests rather than being justified in terms of normative political theory. As European Commissioner Bonino declared over a decade ago, such differentiation between...... descriptive interests and normative ethics is unsustainable in European Union (EU) foreign policy. What are needed are normative justifications that can help inform political choices about foreign policy in the EU's democratic political order. In other words, what are the un-national normative justifications...

    Usually one distinguishes two main types of systems of advantage of the solar energy: the photovoltaic and the photo thermal ones. The first ones are those based on the photovoltaic effect, which allows the direct conversion of the energy of the solar radiation in electrical energy. The second ones transform the solar energy into heat, which can be used in a large variety of processes. By the degree of development of both technologies it is advisable to present them in different sections. Also, there is a great variety of technologies of photo thermal systems that we have classified as technologies for the termosolar generation of electrical power, whose temperatures of operation are high, technologies the solar heating at low temperatures and technologies for industrial heat process.

    The Oswestry Disability Index (ODI) is one of the most common scoring systems used for patients with low back pain (LBP). Although the normative score of the ODI was reported to be 10.19 in a review article, no study has calculated the normative score after adjusting the value based on the age distribution. In addition, none of the previous studies has estimated the cut-off value which separates LBP with disability from LBP without disability. The purpose of this study was to estimate the normative score by adjusting the data for age distribution in Japan, and to determine the cut-off value which separates LBP with disability from LBP without disability. We conducted an internet survey on LBP using the Japanese version of the ODQ. A total of 1,200 respondents, composed of 100 males and 100 females in each age group (from the 20s to 70s), participated in this study. We also asked them to provide information about their backgrounds. We estimated the normative score after correcting for the age distribution of Japan. We also estimated the ODI of those with or without disability, the factors associated with the ODI, and the cut-off value which separates LBP with disability from LBP without disability. The participants' backgrounds were similar to the national survey. The normative score of the ODI was estimated at 8.73. The ODI of the LBP with disability group was 22.07. Those with sciatica and obese subjects showed higher ODI than those without. The optimal cut-off value was estimated to be 12. We defined the normative score and the cut-off value of the ODI.

  5. The normative basis of the Precautionary Principle

    Energy Technology Data Exchange (ETDEWEB)

    Schomberg, Rene von [European Commission, Directorate General for Research, Brussels (Belgium)

    2006-09-15

    Precautionary measures are provisional measures by nature, and need to be regularly reviewed when scientific information either calls for relaxation or strengthening of those measures. Within the EU context, these provisional measures do not have a prefixed 'expiry' date: one can only lift precautionary measures if scientific knowledge has progressed to a point that one would be able to translate (former) uncertainties in terms of risk and adverse effects in terms of defined, consensual levels of harm/damage. Precautionary frameworks facilitate in particular deliberation at the science/policy/society interfaces to which risk management is fully connected. Applying the precautionary principle is to be seen as a normative risk management exercise which builds upon scientific risk assessments. An ongoing scientific and normative deliberation at the science/policy interface involves a shift in science centred debates on the probability of risks towards a science informed debate on uncertainties and plausible adverse effects: this means that decisions should not only be based on available data but on a broad scientific knowledge base including a variety of scientific disciplines. The invocation, implementation and application of the precautionary principle follows a progressive line of different levels of deliberations (which obviously can be interconnected to each other but are distinguished here for analytical purposes). I have listed these levels of deliberation in a table. The table provides a model for guiding all the relevant normative levels of deliberation which are all needed in order to eventually make the legitimate conclusions on the acceptability of products or processes. The table provides a progressive line of those levels of deliberations from the initial invocation of the precautionary principle at the political level down to level of risk management decisions but at the same time show their inter relatedness. Although the table may suggest a

    This study asks whether users’ encounter with normative discourses of lifestyle, consumption, and health on social media such as Facebook gives rise to agency. The theoretical framework draws on reception analysis, for its implied, but central interest in agency that lies at the intersection...... of texts and audiences. Based on a critique of the “participatory paradigm,” a paradigm that situates the locus of agency in the structural opposition between senders and users, in the norms of rational deliberation or in the figure of the activist, gaps are identified which can be filled by adopting...... an explicit focus on the socio-cultural practices of ordinary audiences in their encounters with media discourses. The study investigates user agency on seven Facebook groups and pages with the help of a three-pronged perspective based on the notion of the media–audience relationship as (1) power structure...

    The Maryland consonant-vowel nucleus-consonant (CNC) Test is routinely used in Veterans Administration medical centers, yet there is a paucity of published normative data for this test. The purpose of this study was to provide information on the means and distribution of word-recognition scores on the Maryland CNC Test as a function of degree of hearing loss for a veteran population. A retrospective, descriptive design was conducted. The sample consisted of records from veterans who had Compensation and Pension (C&P) examinations at a Veterans Administration medical center (N = 1,760 ears). Audiometric records of veterans who had C&P examinations during a 10 yr period were reviewed, and the pure-tone averages (PTA4) at four frequencies (1000, 2000, 3000, and 4000 Hz) were documented. The maximum word-recognition score (PBmax) was determined from the performance-intensity functions obtained using the Maryland CNC Test. Correlations were made between PBmax and PTA4. A wide range of word-recognition scores were obtained at all levels of PTA4 for this population. In addition, a strong negative correlation between the PBmax and the PTA4 was observed, indicating that as PTA4 increased, PBmax decreased. Word-recognition scores decreased significantly as hearing loss increased beyond a mild hearing loss. Although threshold was influenced by age, no statistically significant relationship was found between word-recognition score and the age of the participants. RESULTS from this study provide normative data in table and figure format to assist audiologists in interpreting patient results on the Maryland CNC test for a veteran population. These results provide a quantitative method for audiologists to use to interpret word-recognition scores based on pure-tone hearing loss. American Academy of Audiology.

  13. Normative and descriptive rationality: from nature to artifice and back

    Science.gov (United States)

    Besold, T. R.; Uckelman, S. L.

    2018-03-01

    Rationality plays a key role in both the study of human reasoning and Artificial Intelligence (AI). Certain notions of rationality have been adopted in AI as guides for the development of intelligent machines and these notions have been given a normative function. The notions of rationality in AI are often taken to be closely related to conceptions of rationality in human contexts. In this paper, we argue that the normative role of rationality differs in the human and artificial contexts. While rationality in human-focused fields of study is normative, prescribing how humans ought to reason, the normative conception in AI is built on a notion of human rationality which is descriptive, not normative, in the human context, as AI aims at building agents which reason as humans do. In order to make this point, we review prominent notions of rationality used in psychology, cognitive science, and (the history of) philosophy, as well as in AI, and discuss some factors that contributed to rationality being assigned the differing normative statuses in the differing fields of study. We argue that while 'rationality' is a normative notion in both AI and in human reasoning, the normativity of the AI conception of 'rationality' is grounded in a descriptive account of human rationality.

Both political and scholarly assessments argue that ‘we are one of the most important, if not the most important, normative powers in the world’ (Barroso in Peterson, 2008: 69) and that ‘Europe has tremendous normative power’ (Moravcsik, 2010: 18). The normative power approach set out here makes...... it possible to explain, understand, and judge the EU in global politics by rethinking the nature of power and actorness in a globalising, multilateralising and multipolarising era.

    Com o aumento gradativo da população e dos padrões de consumo da sociedade atual, os debates envolvendo as questões energéticas estão sendo cada vez mais frequentes. A base energética do Brasil gira em torno das hidrelétricas, visto que o país possui uma ótima disponibilidade hídrica. Com a escassez dos recursos não renováveis causado pelo consumo desenfreado, voltam-se os olhos para as fontes de energias renováveis, dentre elas destaca-se a energia solar. Com isso o presente estudo teve por ...

  3. An initial test of a normative Figure Of Merit for the quality of overall task performance

    Lemay, Moira; Comstock, J. R., Jr.

    1990-01-01

    An overall indicator, or Figure Of Merit (FOM), of the quality of crew/vehicle system performance is needed to establish the effect of workload on efficiency and to identify overload conditions. A normative FOM is proposed in which performance is measured on a representative task and a normative data base obtained. FOMs for subsequent executions of the task are then reported in terms of weighted deviations from average task performance. Performance of discrete tasks is measured primarily in terms of subtask time and errors. Discrete task performance is then combined with a measure of continuous vehicle control. In order to test the normative FOM procedure, the technique was applied to an existing set of data from a simulated landing task in which standard communications with ATC was compared with a data link communications system. The results indicated that while mean task performance was not affected, task variability, as measured by the FOM, was significantly higher when data link communications were used. In order to establish the sensitivity of the normative FOM method, further testing of the measure is recommended.

    It is possible, and besides logic, the integration of programs such as the electric energy saving and an environmental management system. In managing the consumption and the demand of the electric service, there is an effect on the pollutants emitted for the generation. It is clear that the user in not, and can not be, responsible for the type of fuel used but its importance in project planning is out of question. In its turn the central point of the environmental management system, consists in identifying the main effects on the environment caused by its activities, services and products, as well as the current or potential control level of the enterprise on them.

    The article deals with the interaction of normative and positive theorie of regulation. Those parts of the network which need regulation could be localised and regulated with the help of the normative theory of the monopolistic bottlenecks. Using the positive theory, the basic elements of a mandate for regulation in the sense of the disaggregated economy of regulation are derived.

    Full Text Available Usually associated with a view of freedom as absolute, Sartre’s philosophy seems particularly able to account for the indeterminacy that we experience today in most areas of human experience that have a normative dimension. Without denying that this is a plausible reading, it will be argued here that it is nevertheless a problematic interpretation. On this reading, existentialism seems unable to account for the fact that we are powerfully conditioned by a significant number of factors, which limit our freedom and, in certain situations, make emancipation a normative requirement. It is held here that this problem can be addressed and a less problematic interpretation of Sartre can be defended, once we start to acknowledge that in Sartre we have a variety of notions of freedom that can provide a robust account of our freedom, of authentic choice and of responsibility. Habitualmente asociada a una visión de la libertad como un concepto absoluto, la filosofía de Sartre parece especialmente capaz de representar la indeterminación que experimentamos hoy en día en la mayoría de las áreas de la experiencia humana que tienen una dimensión normativa. Sin negar que ésta es una lectura convincente, no obstante, se va a argumentar que es una interpretación problemática. Con esta lectura parece que el existencialismo es incapaz de representar el hecho de que estamos fuertemente condicionados por un número importante de factores que limitan nuestra libertad y, en algunas situaciones, hacen de la emancipación una necesidad normativa. En este artículo se defiende que se puede abordar este problema, y se puede defender una interpretación de Sartre menos problemática, una vez empecemos a reconocer que en Sartre se pueden encontrar una variedad de nociones de libertad que permiten ofrecer una explicación sólida de nuestra libertad, de elección auténtica y de responsabilidad.

    The total heat flowing from the Earth's interior to the surface is estimated at {approx}42 TW (1012 watts) of which 19% comes from the crust, the 76% comes from the mantle and the 5% comes from the nucleus. The ability to drive the heat of the rocks is very low, causing the need of hundreds of millions of years to exhaust this energy resource. Based on the properties of the renewable heat flow and the long geological times required for its exhaustion, the Earth energy is considered by many scientists as a source of inexhaustible renewable energy, and by its natural availability in all parts of our planet, perhaps the best distributed, together with solar energy. One of the most important advantages of geothermal energy is that its energy can be used not only to generate electric power, but in a large number of applications or direct uses: the heating of buildings, greenhouses or incubators; aquaculture; in various industrial processes (drying products, food packaging, paper manufacturing, chemicals, etc.); balneology for recreational purposes and medicines, and many other applications. In fact, geothermal applications can be integrally one after another or in processes in cascade to fully utilize its energy content.

Basado en las propiedades renovables del flujo de calor y los largos tiempos geologicos requeridos para su agotamiento, la energia de la Tierra es considerada por muchos cientificos como una fuente de energia renovable, practicamente inagotable, y por su disponibilidad natural en todo nuestro planeta, quizas la mejor distribuida, junto con la energia solar.

  12. A normative ethical framework in climate change

    Grasso, M. [Dipartimento di Sociologia e Ricerca Sociale, Universita degli Studi di Milano Bicocca, Edificio U7, via Bicocca degli Arcimboldi 8, 20126 Milan (Italy)

    2007-04-15

    The article spells out four domains of international distributive justice and the consequent criteria of equity, the purpose being to identify a pluralistic normative ethical framework for climate mitigation and adaptation strategies. Justice and equity should play a major role in favouring collective action against climate change, because the more the various dimensions of such action are just, the more any international climate initiative is feasible in principle. As far as mitigation is concerned, the definition of a just initial allocation of endowments focuses on the criterion of differentiated equality, taking account of undeserved inequalities as suggested by Rawls' theory of justice as fairness. With regard to the subsequent exchange of endowments, the Pareto principle, supplemented by the envy-freeness one, is a viable option. Possibly a sound reference for the just financing of adaptation activities is the criterion of differentiated historical responsibility, backed by Rawls' theory of justice as fairness. As regards the allocation of adaptation resources, the criterion of lack of human security, as substantiated in Sen's capability approach, seems promising.

    This study adopted the theory of social representations as a theoretical framework in order to characterize similarities and differences in social representations and normative beliefs of aging for different age groups. The 638 participants responded to self-administered questionnaire and were equally distributed by sex and age. The results show that aging is characterized by positive stereotypes (knowledge and experience); however, retirement is linked to aging, but in a negative way, particularly for men, involving illness, loneliness and disability. When age was considered, it was verified that the connections with the representational elements became more complex for older groups, showing social representation functionality, largely for the elderly. Adulthood seems to be preferred and old age is disliked. There were divergences related to the perception of the beginning of life phases, especially that of old age. Work was characterized as the opposite of aging, and it revealed the need for actions intended for the elderly and retired workers, with post-retirement projects. In addition, it suggests investment in public policies that encourage intergenerational contact, with efforts to reduce intolerance and discrimination based on age of people.

    Full Text Available The concept of “good governance” was used for the first time in the 1989 World Bank Report – Sub-Saharan Africa: From Crisis to Sustainable Growth. A Long-Term Perspective Study – and has already made history in international studies, especially after the breakdown of the communist regimes. The governance has to do with authority, decision-making and accountability.The good governance is defined as the capacity of the government to manage a nation’s affaires, to provide economic development, welfare for citizens, and social protection for the poor. In this article,the concept of good governance is analysed according to two main dimensions: the normative dimension which comprises principles, values and norms that are guiding the international community and the governments in the management of policymaking process;the descriptive dimension which refers to the practical aspects of implementing the good governance’s standards as policies, programmes and structural reforms with the aim of solving or ameliorating the problems of developing countries.

    The IT security law forced the energy industry to implement system certifications for the first time in history. In contrast to most companies in the energy industry, which often only knew about product certifications, the energy industry now has to enter new territory. Certification companies receive their legitimation in Germany through DAkkS. The DAkkS is embedded in the context of European Union law. The work of the certification companies is determined by the specifications of the DAkkS as well as by the requirements of the ISO/IEC standards. These regulations should in any case be known to a certification customer so that he knows what a certification company does or does not do. In addition, a certification customer must also know which evidence must be presented in the sense of a reference standard against the certification company. The concrete evidence in this essay is based on an ISO/IEC 27001 certification in conjunction with the IT Security Catalog of the Bundesnetzagentur. With all this knowledge, the cooperation with the certification company will not be a problem for system certification.

    Full Text Available This survey provides an overview of implemented systems, theoretical work, as well as studies of biological systems relevant to the design of artificial learners trying to figure out what a human teacher would like them to do. Implementations of artificial learners are covered, with a focus on experiments trying to find better interpretations of human behavior, as well as algorithms that autonomously improve a model of the teacher. A distinction is made between learners trying to interpret teacher behavior in order to learn what the teacher would like the learner to do on the one hand, and learners whose explicit or implicit goal is to get something from the teacher on the other hand (for example rewards, or knowledge about how the world works. The survey covers the former type of systems. Human teachers are covered, focusing on studies that say something concrete about how one should interpret the behavior of a human teacher that is interacting with an artificial learner. Certain types of biological learners are interesting as inspiration for the types of artificial systems we are concerned with. The survey focus on studies of biological learners adopting normative conventions, as well as joint intentionality team efforts.

    2012-01-01

    Tobacco-related deaths in Vietnam are forecast to climb from 40 000 annually to 70 000 by 2030. Previous research in Western nations has found social factors to be important determinants of adolescent smoking. Because these factors remain unexplored in Vietnamese youth, the purpose of this study was to examine social normative beliefs regarding smoking in a school-based sample of North Vietnamese adolescents and the association of these factors with smoking behavior and susceptibility to smoking. Three measures of normative beliefs regarding smoking were evaluated in cross-sectional surveys of secondary students. Of the 3 measures, parent/peer disapproval was the most consistent normative belief associated with smoking behavior and susceptibility to smoking. Youth smoking prevention programs should consider assessing and taking into account normative beliefs and develop strategies that provide accurate information about the actual prevalence of smoking, the types of individuals who smoke, and approval/disapproval of smoking by parents and peers.

    We consider two distinct influences that drive conformity behaviour. Whereas informational influences facilitate adaptive and accurate responses, normative influences bias decisions to enhance social acceptance. We explore these influences from a perspective of perceptual and value-based decision-making models and apply these models to classical works on conformity. We argue that an informational account predicts a surprising tendency to conform. Moreover, we detail how normative influences fit into this framework and interact with social influences. Finally, we explore potential neuronal substrates for informational and normative influences based on a consideration of the neurobiological literature, highlighting conceptual shortcomings particularly with regard to a failure to segregate informational and normative influences.

    2012-08-01

    We addressed several issues concerning children who show gender non-normative (GNN) patterns of peer play. First, do young children with GNN peer preferences differ from children with gender normative (GN) peer preferences in problem behaviors? Second, do GNN and GN children differ in sociability and isolation and do they have differential socialization opportunities with externalizing, internalizing, and socially competent peers? We employed a Bayesian approach for classifying children as GNN based on their peer preferences as compared to their peers using a sample of Head Start preschool children from a large Southwestern city (N = 257; 53 % boys; M age = 51 months; 66 % Mexican American). To calculate socialization opportunities, we assessed affiliation to each child in the class and weighted that by each peer's characteristics to determine the exposure that each child had to different kinds of peers. GN children of both sexes interacted more with same-sex peers, which may limit learning of different styles of interaction. As compared to GN children, GNN children exhibited more engagement in other-sex activities and with other-sex play partners and GNN children experienced somewhat fewer peer interactions, but did not differ on problem behaviors or social competence. Boys with GNN peer preferences had increased exposure to peers with problem behaviors. GNN girls experienced little exposure to peers with problem behaviors, but they also had little exposure to socially competent peers, which may reduce learning social skills from peers. Implications of these findings for future socialization and development will be discussed.

  18. The Energy Regulatory Commission (1). Law of the Comision Reguladora de Energia

    International Nuclear Information System (INIS)

    1995-01-01

    The Energy Regulatory Commission. Reforms to the Electric Energy Public Service Law (1992) and the Regulatory Law of Article 27 on Petroleum (1995) have brought about fundamental changes in the electric and natural gas industries. The legal reforms explicitly permit the private sector to construct, operate, and own, systems of electric generation and natural gas transportation, storage and distribution. The participation of the private sector in these areas required a redefinition in the government regulatory institutions. Accordingly the Federal Congress enacted the law of the Comision Reguladora de Energia (CRE) in 1995. The CRE law expands the scope of the CRE's authority and the breadth of its powers beyond those established when it was initially created in 1993. The CRE commenced operations in January 1994 as a decentralized technical and consultative body of the Energy Ministry. The decree that created the Commission limited the scope of its authority to an analysis and consultative role applicable only to the electric industry. (Author)

  5. The Normative Impact of Unemployment Insurance : A European Perspective

    2015-03-01

    Full Text Available The debate on classification instruments for social security regimes opened by Esping-Andersen (1990 usually neglects the examination of the normative impact of the welfare state. This article focus on this latter through an analysis of systems of protection against unemployment in 11 of the European countries included in the database known as the Mutual Information System on Social Protection (MISSOC.We show in this article that unemployment insurance only recognize legal, authorized and declared salaried employees who have resided in the country for a set period of time, which confirms the close link between social policy and nationality, with some foreign workers being excluded from the circle of beneficiaries because of these norms. Unemployment insurance also always considers jobs as rare social goods - workers are expected to hold on to them, but they are declined differently along a person’s life course. The dominance of the male employment norm and the complete lack of consideration given to domestic labour by unemployment insurance contribute to structuring gendered roles as separate and hierarchically organized. Disparities between countries, whether related to contextual differences or to the history of the local welfare state, do not weaken these arguments since they are not founded upon fundamentally different conceptions of unemployment.

    The potential of solar water heating systems through solar energy in Brazil is excellent due to the climatic features of the country. The performance of these systems is highly influenced also by the materials used to build it and by the dimension of its equipment and components. In face of global warming, solar energy gains more attention, since it is one of the renewable energy that will be largely used to replace some of the existing polluting types of energy. This paper presents the improvement of a software that conducts simulations of water heating systems using solar energy in thermosyphon regime or forced circulation. TermoSim, as it is called, was initiated at the Solar Labs, and is in its version 3.0. The current version is capable of simulating 6 different arrangements' possibilities combined with auxiliary energy: systems with solar collectors with auxiliary energy with gas, electric energy, internal electric energy, electric energy in series with the consumption line, and no auxiliary energy. The software is a tool to aid studies and analysis of solar heating systems, it has a friendly interface that is easy to comprehend and results are simple to use. Besides that, this version also allows simulations that consider heat losses at night, situation in which a reverse circulation can occur and mean efficiency loss, depending on the simulated system type. There were many simulations with the mathematical models used and comparisons were made with the climatic data of the city of Caxias do Sul, in Rio Grande do Sul state, in Brazil, determining the system with the most efficient configuration for the simulated water consume profile. The paper is finalized with simple economic analyses with the intention of foreseeing the time for payback on the investment, taking into account the current prices for electrical energy in the simulated area and the possible monthly economy provided with the use of a solar energy heating system.

    The use of alternative energy systems in the current days is an urgent necessity due to the problems that the planet is facing as the heating and loss of ozone layer. The scarcity of conventional energy is another problem that must be solved for the future of humanity. It must be considered that the people are inhabiting places moved away not always with available energy. The application of technologies as automation and control can help us to solve this problem. Therefore, this work aimed at apply an equipment of industrial usage, the Programmable Logical Controller, PLC, in alternative energies systems, as eolic generation and photovoltaic generation used for water pumping, aiming the automatic control and the efficiency in the places where it has simultaneous availability of these sources, based in criterion of priority that previously established itself between them. It was made a hydraulic and energetic evaluation of the energy system, eolic and photovoltaic, used in the automatic control system of pumping, in the place of accomplishment of the experiment, according to previously established physical conditions. The results have shown that the control system using the PLC is practicable and has trustworthiness. The program developed can be adapted for the use with several power plants in a specific application place. The photovoltaic system of pumping, using a polycrystalline of 70 Watts connected to a pump Shurflo 8000, showed to be efficient with significant flows in almost all the months. The eolic system of pumping, using an eolic generator of 400 Watts assembled in place of experiment, did not demonstrate energetic capacity for use in this specific type of application. (author)

    Increase the electrical distribution network quality it's a permanent interesting of energy companies. Therefore, quality services with acceptable values must be offers. In direct form this involves to manage efficiently all distribution system. Nowadays, this supervision is carried out with Geographic Information System (GIS) tools associate with calculation of demands transformers, result of correlation curve kWh versus KV A. Simple linear regression is used to estimate this curve, which make the process not too accuracy. To estimate consumers loads, the traditional methodology consider only end consumption, refusing the characteristic of different kinds of consumers: residential, commercial, industrial, rural and others. This paper present a model based hybridism between Artificial Neural Network (ANN) and Genetic Algorithm (GA), that can identify on load curve acquired any point of distribution system, the portions of consumption relatives to each one of main consumers sectors in that point. Besides, is suggested to the same application an ANN type Multi-Layer Perceptron, with the purpose to compare the showing results and to verify the advantages of hybridism use. The Hybrid System proposed use GA to the ANN training, in other words, the determination of best values to the ANN synaptic weights. Definite the work methodology, the practical valuation of the model starts, and the results presented by hybrid system are compared with those generates by ANN training by the conventional method well-know Back propagation Error (BP). The practical application propose that load curve acquired been analyze in any point of distribution system. Knowing this curve, the system should identify instant consumption quantities, relative to each one of main consumers sectors: industrial, commercial and residential. Subsequently are consider oscillations about these curves, in way to approach the real situation. The initial result indicated a best performance of conventional

    Electrical utilities have been constantly searching for ways to improve the management of their power distribution systems.The continuously growing demand as well as the society`s requirements for a high quality service have ensured the need to apply geo processing technologies integrated to AM/FM (Automated Mapping/Facilities Management) systems. The geographic information systems (GIS) are perfectly adapted to the requirements of the distribution network management, since both involve manipulation, treatment, analysis and visualization of great volumes of geo referenced data having related spatial and topological features, aggregated to descriptive attributes of entities inherent to distribution networks. However, there are difficulties in the processes of acquisition of the necessary data bases (mapping and network), since those tasks absorb most part of the required investments. There have been attempts to solve this problem through the development of new data acquisition techniques, specially a more intense utilization of digital collectors connected to GPS (Global Positioning System) receptors. In spite of such difficulties, most utilities have chosen to develop AM/FM/GIS systems, since it is through this technology that they will assure a high quality level of their services and obtain all the benefits arising from a improved equipment management and process optimization.

    Hungary will continue to experience a high burden of disease and death from lung cancer and other tobacco-induced disease unless there is a significant reduction in youth smoking. Social factors have been found to be among the most important determinants of adolescent smoking, yet few studies have investigated social normative beliefs in Hungarian youth. The purpose of the current study was to investigate three measures of smoking normative beliefs thought to influence adolescent smoking: perceived prevalence of smoking; perceived popularity of smoking among successful/elite elements of society; and perceived disapproval by friends and family. A cross-sectional school-based survey of eighth grade (n = 258) and 12th grade (n = 288) students in Mako, Hungary was conducted to assess social normative beliefs about smoking, current smoking, ever smoking, and susceptibility to smoking. The association of the normative beliefs with the smoking behavior variables was examined through logistic regression analysis, and the underlying factor structure of the normative belief items in the current sample was determined through factor analysis. The percent of boys reporting current smoking was 40.5% in 12th grade and 27.0% in eighth grade. Among girls, the percent was 44.0% of 12th graders and 29.1% of eighth graders. Parent/peer disapproval was the most consistently associated normative belief with smoking behavior and susceptibility to smoking across both samples. Youth smoking prevention programs should consider assessing and taking into account normative beliefs and develop strategies that provide accurate information about the actual prevalence of smoking, the types of individuals who smoke, and approval/disapproval of smoking by parents and peers. © 2011 The Authors.

    Normative eating cues (portion size, social factors) have a powerful impact on people's food intake, but people often fail to acknowledge the influence of these cues, instead explaining their food intake in terms of internal (hunger) or sensory (taste) cues. This study examined whether the same biases apply when making predictions about how much food a person would eat. Participants (n = 364) read a series of vignettes describing an eating scenario and predicted how much food the target person would eat in each situation. Some scenarios consisted of a single eating cue (hunger, taste, or a normative cue) that would be expected to increase intake (e.g., high hunger) or decrease intake (e.g., a companion who eats very little). Other scenarios combined two cues that were in conflict with one another (e.g., high hunger + a companion who eats very little). In the cue-conflict scenarios involving an inhibitory internal/sensory cue (e.g., low hunger) with an augmenting normative cue (e.g., a companion who eats a lot), participants predicted a low level of food intake, suggesting a bias toward the internal/sensory cue. For scenarios involving an augmenting internal/sensory cue (e.g., high hunger) and an inhibitory normative cue (e.g., a companion who eats very little), participants predicted an intermediate level of food intake, suggesting that they were influenced by both the internal/sensory and normative cue. Overall, predictions about food intake tend to reflect a general bias toward internal/sensory cues, but also include normative cues when those cues are inhibitory. If people are systematically biased toward internal, sensory, and inhibitory cues, then they may underestimate how much food they or other people will eat in many situations, particularly when normative cues promoting eating are present.

    This paper presents a project to establish one electrical system, isolated by photovoltaic energy, in a residence located approximately 7 km from the town of Barra da Estiva, BA, which do not receive electricity through the transmission system, necessitating generation of electricity on the spot to ensure that this family has some benefits offered by electricity. The scaling was done to two situations: one that serves only the lights and another that allows for a more complete electrification to the region. Meanwhile, the deployment of new technologies in remote places such stocks requires new attitudes and forms of organisations for the adoption, management and maintenance of the system chosen, therefore, social aspects of acceptance of this technology are also discussed.

    The power system static operation planning has a main objective the determination of performance strategies which satisfy operational criteria. A fuzzy set decision model which takes the load attainment and the compromise between optimality and critical operational constraints into account is presented. The prime characteristic of this methodology is the incorporation of the planner`s preferences structure in a decision process modeled by fuzzy sets. A routine of optimal power flow calculation is used as a computational tool for solving the nonlinear model of the electric power system and for defining the universe of discourse of the decision-making problem. tests were carried on a 30-bus IEEE system in order to find a compromise solution of electric operational goal versus reactive power generation limits. Results and conclusions are presented. (author) 28 refs., 32 figs.

    This work presents an analysis of the reliability of the emergency power supply system, of a small size nuclear power reactor. Three different configurations are investigated and their reliability analyzed. The fault tree method is used as the main tool of analysis. The work includes a bibliographic review of emergency diesel generator reliability and a discussion of the design requirements applicable to emergency electrical systems. The influence of common cause failure influences is considered using the beta factor model. The operator action is considered using human failure probabilities. A parametric analysis shows the strong dependence between the reactor safety and the loss of offsite electric power supply. It is also shown that common cause failures can be a major contributor to the system reliability. (author)

    This work presents an automatic positioning system for photovoltaic panels, in order to improve the conversion of solar energy to electric energy. A prototype with automatic movement was developed, and its efficiency in generating electric energy was compared to another one with the same characteristics, but fixed in space. Preliminary results point to a significant increase in efficiency, obtained from a simplified process of movement, in which sensors are not used to determine the apparent sun's position, but instead of it, the relative Sun-Earth's position equations are used. An innovative movement mechanical system is also presented, using two stepper motors to move the panel along two-axis, but with independent movement, contributing, this way, to save energy during the positioning times. The use of this proposed system in rural areas is suggested. (author)

The CDP allows multiple objective optimization that does not, necessarily, result in a single optimal solution. First, a literature review covers published works related to Artificial Intelligence applications to Electric Power Distribution Systems, emphasizing feeder restoration and reconfiguration. Some concepts related to Artificial Intelligence are described, with particular attention to Planning and to Constrained Decision Problems. Following, an Electric Power System planning model is addressed by using the CDP tool. Some case studies illustrate the Distribution Planning model, which are compared with standard optimization models. Concluding, some comments establishing the possibilities of CDP applications are followed by a view on future developments. (author)

    We addressed several issues concerning children who show gender non-normative (GNN) patterns of peer play. First, do young children with GNN peer preferences differ from children with gender normative (GN) peer preferences in problem behaviors? Second, do GNN and GN children differ in sociability and isolation and do they have differential socialization opportunities with externalizing, internalizing, and socially competent peers? We employed a Bayesian approach for classifying children as GNN based on their peer preferences as compared to their peers using a sample of Head Start preschool children from a large Southwestern city (N = 257; 53% boys; M age = 51 months; 66% Mexican American). To calculate socialization opportunities, we assessed affiliation to each child in the class and weighted that by each peer’s characteristics to determine the exposure that each child had to different kinds of peers. GN children of both sexes interacted more with same-sex peers, which may limit learning of different styles of interaction. As compared to GN children, GNN children exhibited more engagement in other-sex activities and with other-sex play partners and GNN children experienced somewhat fewer peer interactions, but did not differ on problem behaviors or social competence. Boys with GNN peer preferences had increased exposure to peers with problem behaviors. GNN girls experienced little exposure to peers with problem behaviors, but they also had little exposure to socially competent peers, which may reduce learning social skills from peers. Implications of these findings for future socialization and development will be discussed. PMID:22528037

    A debunking argument has been recently levelled against normative realism. According to this line of reasoning, most of our normative beliefs have been strongly influenced by evolutionary forces. As evolution is a non-truth-tracking process, this influence may lead our normative beliefs off track. If so, normative realists need to provide an explanation of how it is possible that our normative beliefs track stance-independent truth, or of how their falsity could be spotted, when evolution pow...

    2017-01-01

    Full Text Available Trafficking in human organs is a specific and complex criminal phenomenon that takes place in several phases, with the participation of a large number of actors, often covering several jurisdictions. To effectively countering are necessary conceptual and terminological demarcation of organ trafficking from other similar phenomena, fundamental scientifically research of its shape and dynamics, and the construction of an adequate legislative framework, both at the national and international level. This paper first analyses the conceptual - terminological framework in which research of organ trafficking is range, and then presents a review and analysis of the development of ethical and normative international standards aimed at prevention and suppression this phenomenon. In the end, we analysed the current solutions in the domestic legislation. Nowadays, there are two parallel legislative regime that regulate the matter of organ trafficking. The first legislative regime that organ trafficking treated exclusively as a modality of transnational crime of human trafficking, and a second, recent, that organ trafficking treats as forbidden (incriminating activity that violates a regulatory system of organ (tissue cells transplantation.

    The ``Programa Universitario de Energia (PUE)`` (University Energy Program) of the Universidad Nacional Autonoma de Mexico (UNAM) through the project ``Ecologic Control of The University Campus`` has the objective of instrumenting policies for the rational use of the electric energy in the UNAM installations. The PUE has performed a series of activities aimed at the establishment of an integral program for the electric energy management in the UNAM. This program has to consider the measures for energy saving (MES) of general kind and to promote a series of specific measures to be adequated and implemented for each one of the departments. The success in establishing a series of MES compels to quantify its effects, to register and to analyze them to be in position of enhancing them, since it must be kept in mind that something that can not be measured can not be improved. For this purpose the PUE is developing a continuous monitoring pilot network of electric energy with local and remote access and an automated metering system. Two monitoring schemes are experimented, one commercial metering equipment and another one with own metering technology.

    The Delis-Kaplan Executive Function System (D-KEFS) Trail Making Test (TMT), a modification of the original TMT, was created to isolate set-shifting (Letter-Number Switching) from other component skills. This was accomplished by including four baseline conditions (Visual Scanning, Number Sequencing, Letter Sequencing, and Motor Speed) and by placing equal numbers of stimuli in the three sequencing conditions. Given that some studies with the original TMT demonstrated a significant effect of education and intellectual functioning on performance, we utilized the D-KEFS national standardization sample to examine the effects of education and vocabulary level-i.e., Vocabulary subtest from the Wechsler Abbreviated Scale of Intelligence (WASI)-on the D-KEFS TMT. The results indicate a significant effect of these variables on each D-KEFS TMT condition. Normative tables for education- and vocabulary-adjusted scaled scores based on the database from the D-KEFS national normative study were generated.

    The determination of an appropriate catchment area for a hospital providing highly specialized (i.e. tertiary) health care is typically a trade-off between ensuring adequate client volumes and maintaining reasonable accessibility for all potential clients. This may pose considerable challenges, especially in sparsely inhabited regions. In Finland, tertiary health care is concentrated in five university hospitals, which provide services in their dedicated catchment areas. This study utilizes Geographic Information Systems (GIS), together with grid-based population data and travel-time estimates, to assess the spatial accessibility of these hospitals. The current geographical configuration of the hospitals is compared to a normative assignment, with and without capacity constraints. The aim is to define optimal catchment areas for tertiary hospitals so that their spatial accessibility is as equal as possible. The results indicate that relatively modest improvements can be achieved in accessibility by using normative assignment to determine catchment areas. Copyright © 2017 Elsevier Ltd.

    2018-01-01

    Full Text Available The normative and legal provision of the strategic planning of regional development is presented. Features of strategic planning at the regional level in modern conditions are considered. The problems that prevent the use of the system of strategic planning without giving an opportunity both to develop significant plans and to ensure their realization were analyzed. It has been determined that Ukraine as a whole has a normative and legal base for the efficient development of regions, but it requires systematization and harmonization, as some issues are still unresolved. Proposals for further improvement of institutional mechanisms of strategic planning at the regional level are presented, which will improve the quality of development of strategic documents in the process of adoption of managerial decisions. Prospect for further research is the formation of scientifically substantiated proposals to improve the legislation regulating the issues of planning and implementation of strategies for socio-economic development of regions.

    Approximately, 50 % of worldwide primary energy consumption is done in the form of heat in applications with a temperature lower than 250 degree centigree (low-medium temperature heat). These data clearly demonstrate the great potential of solar thermal energy to substitute conventional fossil fuels, which are becoming more expensive and are responsible for global warming. Low-medium temperature solar thermal energy is mainly used to obtain domestic hot water and provide space heating. Active solar thermal systems are those related to the use of solar thermal collectors. This study is dealing with low temperature solar thermal applications, mainly focusing on active solar thermal systems. This kind of systems has been extensively growing worldwide during the last years. At the end of 2006, the collector capacity in operation worldwide equalled 127.8 GWth. The technology is considered to be already developed and actions should be aimed at favouring a greater market penetration: diffusion, financial support, regulations establishment, etc. China and USA are the leading countries with a technology based on evacuated tube collectors and unglazed collectors, respectively. The rest of the world markets are dominated by the flat glazed collectors technology. (Author) 15 refs.

    Energy and water resources are related in various ways, among which is the use of electric power in Water Supply Systems (WSS). This dissertation identifies actions that can be carried out under the adoption of energy management systems by sanitation companies in order to better use energy resources and, therefore, water resources. The importance of the input electric power to the WSS is presented, as well as the inefficiency of its use mainly due to losses in distribution networks, inappropriate operational routine and inadequate equipment. Two studies were conducted to evaluate the performance of possible actions for energy management in the WSS. The first action was the energy performance indicators use in hypothetical WSS, and the second, the use of EPANET 2.0 simulation software to verify the feasibility of the frequency converter equipment in the water network distribution of the Federal University of Rio de Janeiro's Environmental Sanitation Centre.

    Integration of power generation and transmission systems can provide a better utilization of energy resources and increase systems reliability. Given that Brazilian interconnection with Argentina, which represents the major Brazilian interconnection with neighboring countries, is used basically in winter months or in situations of unfavorable hydrology, this paper aims to demonstrate that power exchange between these two countries can be much higher than currently observed, resulting in greater benefits for producers and consumers of electricity in both countries, and that these benefits can also be obtained through better use of existing and planned interconnections between South American countries. To estimate the potential for power exchange between the electrical systems of Brazil and Argentina, three sets of simulations using the Brazilian Energy Plan (PDE 2010-2019) deck for Newave model, available from EPE, were made. These simulations consider the possibility that: (i) electricity is exported from Brazil to Argentina (II) electricity is imported from Argentina and (III) electricity is exchanged in both directions. The simulation results indicate that, despite rising operational marginal costs, significant amounts of electricity can be exported to Argentina at relatively low prices, depending on hydrological conditions. Moreover, the possibility of electricity imports from Argentina can reduce the operational costs of Brazilian system, as well as minimizing the risk of shortages. This work shows that the interconnections between Brazil and Argentina may be better used to benefit producers and consumers in both countries. Therefore, it is necessary to define an effective contractual and operational model for power trading and electricity transfer between these countries with the objective of promoting stability and mutual trust. Finally, studies to evaluate the potential for electricity exchange between South American countries are specially important

    The Brazilian land receives a great amount of solar radiation all over the year, therefore, because both the culture and practical aspects, Brazilians use in a non-moderate way the electricity to boil the water for human bath in the rural homes, in the lower income residences even at part of the medium class homes. That happens due to the very low price of an electrical shower, about US$ 6,5. In fact, that way of heating water is largely used because, besides the very low electrical shower price, it is not necessary to install a complete hot water both hydraulic and electrical building systems, but just both single hydraulic pipes and electrical devices. On the other hands, at rural regions where the electricity does not achieve the rural people uses firewood in order to get hot water for human bath. At the rural places the use of electrical showers has meaning an increase in the electrical transformers powers, heavier electrical transmission rural lines, with greater prices and, at the urban zones, the use of electrical showers in the lower social classes has contributed to a more expressive electrical load at the nacional electrical system load peck, between 5:30 to 8:30 a.m. The public administration, mostly, does not take into account both social, economic and environmental costs in order to think about the electricity offer. The solar heating systems, generally used in Brazil, conserves the same reservoirs used in France at 1880. Therefore, this paper presents some technical subsidies applied to rural homes, even to lower income people's homes aiming to stimulate the Brazilian public authorities to make a public police to facilitate both the industrialization and dissemination of solar heating systems, appropriate to the rural area, with lower costs, compounded by good technology equipment, with guarantee of lasting and quality.

    Integration of power generation and transmission systems can provide a better utilization of energy resources and increase systems reliability. Given that Brazilian interconnection with Argentina, which represents the major Brazilian interconnection with neighboring countries, is used basically in winter months or in situations of unfavorable hydrology, this paper aims to demonstrate that power exchange between these two countries can be much higher than currently observed, resulting in greater benefits for producers and consumers of electricity in both countries, and that these benefits can also be obtained through better use of existing and planned interconnections between South American countries. To estimate the potential for power exchange between the electrical systems of Brazil and Argentina, three sets of simulations using the Brazilian Energy Plan (PDE 2010-2019) deck for Newave model, available from EPE, were made. These simulations consider the possibility that: (i) electricity is exported from Brazil to Argentina (II) electricity is imported from Argentina and (III) electricity is exchanged in both directions. The simulation results indicate that, despite rising operational marginal costs, significant amounts of electricity can be exported to Argentina at relatively low prices, depending on hydrological conditions. Moreover, the possibility of electricity imports from Argentina can reduce the operational costs of Brazilian system, as well as minimizing the risk of shortages. This work shows that the interconnections between Brazil and Argentina may be better used to benefit producers and consumers in both countries. Therefore, it is necessary to define an effective contractual and operational model for power trading and electricity transfer between these countries with the objective of promoting stability and mutual trust. Finally, studies to evaluate the potential for electricity exchange between South American countries are specially important

    In this work a primary standard system was established for low energy X-rays (10 kV to 50 kV), using a free air ionization chamber with concentric cylinders, Victoreen (Model 481-5), at the Calibration Laboratory of Instruments (LCI) of the Instituto de Pesquisas Energeticas e Nucleares (IPEN/CNEN-SP). For this, a new ionization chamber alignment protocol was developed for the radiation system and a modification on the micrometer housing used for the movement of the internal cylinders was ma de. The results obtained for the stability and characterization tests showed to be within the limits established by the standards IEC 61674 and IEC 60731. The correction factors for photon attenuation in the air, transmission and scattering in the diaphragm, scattering and fluorescence and ion recombination were also determined. These values were compared with those obtained by the German primary standard laboratory, Physikalisch-Technische Bundesanstalt (PTB), showing good agreement. Finally, the absolute values of the quantity air kerma rate for the standard qualities direct beams MWV28 and WMV35 and the attenuated beams WMH28 and WMH35 were determined; the results are in agreement, with a maximum difference of 3,8% with the values obtained using the secondary standard system of LCI.

    A study is carried out as a first draft to evaluate the technical feasibility of wind energy as a supplement of the existing power supply system available in isolated locations in Southern Chile, such as, Sea Mayors and Lighthouses. At present, most of these places are accessible only by sea and are supplied by diesel generators. This project aims to reduce the oil consumption which is transported in these remote zones by Chilean Navy ships. The responsible department of the Chilean Navy purchased a small Savonius type vertical 1000 Watts wind turbine to assess the feasibility of this project. This aims to encourage the use of wind, which is strong and permanent in these extreme latitudes of the southern zone. Evaluations of main parameters are conducted to obtain the generator rate and maximum operating range, e.g. the main variables that determine a wind generation system to match electricity demand, the types of wind generators and its power. Wind potential in the region is determined and an autonomous hybrid wind-diesel.

    The aim of this work was to evaluate the energy balance and the sustainability in the hay production through seven years data from a Intensive System of Milk Production, located in the region of Coronel Pacheco/MG Brazil. To the energy matrix determination, the categories of direct and indirect energy were considered. The energy inputs occurred in the implanting and establishing of the crop were distributed in the years considered as useful life. The direct energy, relative to the inputs, had larger participation that the indirect one, being the percentiles found of 93.05 and 6.95, respectively. The main consumer of indirect energy was the tractor, which turns on all the implements, followed by the irrigation system. The estimated energy efficiency by the process was of 3.19. Most of the used direct energy was that derived from fossil resources, in the form of fuel (diesel). The use of organic fertilizer, of poultry litter, promoted a relative reduction in the consumption of energy originated from fertilizer derived from fossil resources. With the obtained results, it was concluded that, despite of the several sources of energy consumption, the production of alfalfa hay is sustainable and efficient in the energy conversion. (author)

    This paper aims to outline perspectives on the electricity production through Grid-Connected Photovoltaic Systems (GCPS), in Brazil, and its insertion on a large scale in the energy matrix, as a supplementary power generation source. The GCPS bring several benefits to the Electrical Sector and the environment by producing energy cleanly and quietly in the places of consumption, avoiding the construction of large power plants and avoiding additional costs with transmission and distribution. In general, these systems can be integrated into the buildings architecture, taking advantage of the rooftop of pre-existing buildings. But, although it has high solar potential, Brazil had been installed a capacity of only 161.32 kWp GCPS until December 2009, a value considered negligible compared, for instance, with 4.5 GWp installed in Europe alone in 2008. This study shows that the cost of generation from a GCPS is still high, reaching to 2.4 times higher than the average residential tariff practiced in Brazil, which turns the technology impracticable commercially. But it shows a trend of equalization between these two values in the next decade for various locations, which will certainly make the GCPS to be considered as an alternative for expanding the energy supply. But for the lack of appropriate technical criteria do not affect the spread of this technology in the future, it is necessary a correct regulation of this activity by the staff of the Electrical Sector.

    Renewable energy is all kind of energy produced from a natural source that not diminish because its utilization is 'renewable'. More and more renewable energy resources are used, because they offer multiple advantages such as the energy output facility in small scale and because they are entirely compatible with the environment. The renewable energy used in this project is the photovoltaic solar energy, obtained by the direct conversion of the solar energy in electric energy through the use of solar cells, that can be of several kinds, being the most common of silicon. The main advantage of photovoltaic system is the generation of clean electric energy, or either, generates energy without emitting pollutant and without destroying the environment, moreover is an inexhaustible source of energy. The main disadvantage is, nowadays, the high cost and its low efficiency, so to continue developing it is necessary establish capable mechanisms to make it possible. The search of these mechanisms of incentive becomes-itself a lot important, because the renewable energy and not conventional do not produce a financial return to the investor properly said, but brings lots of benefits to the community, the society and to the environment. This project has the purpose of create an electric energy generation system through solar photovoltaic modules to carry batteries of a motorized wheelchair. An electric wheelchair is moved by electric motors of direct current that are feed by batteries, permitting a medium autonomy of 10 km by load. The batteries are recharged by a battery supplier. This operation should be carried out daily in a space of 6 to 8 hours. According to the Demographic Census realized in 2000 carried out by the IBGE, Brazil has around 1.416.060 physical deficient, which 861.196 are men and 554.864 are women. From a request of a user of electric wheelchair the idea of this project was shown up. The user complained that he stayed a long time carrying his seat

    Great problems are found by who need to get a power plant capable to mostly make possible the deriving food production of the fruits. The use of the electric energy of the plants and micron-plant is one of the main factors for the rise in the cost of the production. The use of alternative sources of energy sells at a loss a little this cost. Of this form, this project of integrated system of production of energy for agroindustry, supported for the CNPq, becomes advantageous all the investments that come to be made in this direction. The objective of the research is to develop a new synthesis of processes for use of vegetal biomass (wood) for production of the applied electric energy in the process of manufacture of jelly of fruits with co-production of activated coal. Our project of residual biomass produces energy from the wood saw pyrolysis and gasification. And also uses the substitution of the glucose found in the sugar for the pectin, proceeding from the rinds of fruits. Comparative results indicate that this substantiates (pectin) is sufficiently efficient in the control of the cholesterol level of the blood and also is very rich in the energy supply for the people who consume them. After carried through bibliographical research on the current state of the technology of the production of energy based on the vegetal biomass of firewood, processes of term conversion, reactor of activation and equipment, to leave of this had been developed engineering projects, with the use of the tool Super ProDesigner 4.9. Some simulations of processes of fast pyrolysis, gasification, separation of bio oil, generation of energy including system of integration of energy production as innovation of the considered work had been made. To leave of this, two scenes had been developed: one, the current process of production and the other, our innovation, being studied at great length the project of investment and costs, analysis of viability and cash flux using software Orcamento

    Tools and criteria for Cost-Benefit Analysis (ACB) of energy saving in bioclimatic designs (DB) are presented, for which a reference project is established. Based on the traditional design of air conditioning of a building and with the support of this one, the estimation of costs and benefits of the same building is made; but with passive systems. The tools used consider related resources such as time and money. Criteria are used such as: Present value (VP), Equivalent Annual Cost (EAC) and the Cost of the conserved Energy (CEC). The costs related to the construction, maintenance and operation of the design are taken into consideration. The differences between the design of reference and the Bioclimatic Design, established from the application of these criteria, allow evaluating the economic margin as far as operation and maintenance. Finally, the cost of the conserved energy of the bioclimatic measures is evaluated as an initiative for energy saving and calculates the present value from them in all of the period of useful life of the bioclimatic design.

    The energy assumed a preponderant paper to the current societies because it became the number spine of both economic and social activities developed. Technological advances and the economic and social development of the nations, was based on the transformation and use of natural resources in products and services. Such transformation if gave more of accented form from the Industrial Revolution where the substitution of activities until then carried through by the man, for the job of machines, transformed the way of life and the behavior of the society. Particularly the projection of demand of energy send to the following duality: the problem should be evaluated in a wide way, in other words, considering the whole range of component variables of the decision process for generation and allocation of the energy supply; however, in a local way regarding with the search of models that optimize of the energy potentials and the consequent search of value added market. Historically the forecast of the energy demand uses the GDP mainly. It is presupposed that the association of such variables to the areas that these act, or polygons that delimit them, it happens in a homogeneous way and that the limits of such areas constitute an identified change of behavior. However, this premise is false, because such polygons are defined for operational and / or politician criteria not having warranty that such distributions are really homogeneous. As solution, the development and use of decision support systems based on GIS (Geographic Information System) technology has been along the last years a powerful modeling and simulation tool. The objective of this paper is to introduce the application of techniques of spatial analysis in the activity of projection, activity that is inherent to the forecast energy demand, to mitigate the future developments of scientific models and applications associates.

    Full Text Available Assuming that there is a "neuroscientific turn" in moral philosophy, I will be discussing in this paper how neurophilosophy could shed light on the normative problems raised by a naturalistic project of ethical and social research, particularly related to the question of the articulation between the biological evolution of human species and the social and historical evolution of society and social groups. Taking a critical approach to naturalism and normative theories, I argue that there is a neurophenomenological deficit in naturalism (particularly in the versions of naturalism that follow the program of a naturalized epistemology and in the normative theories (particularly in the critical theory and I put forward a version of social constructivism that combines the neuroscientific and neurophilosophical models of Antonio Damasio and Jesse Prinz.

    This paper uses attachment theory as a lens for reviewing contemporary research on how adults cope with marital separation and loss. The first section of the paper discusses the process of normative attachment reorganization, or the psychology of adaptive grief responses following relationship transitions. We argue that changes two processes, in particular, can be uses to track changes in this normative reorganization process: narrative coherence and self-concept clarity. The second section of the paper suggest that individual differences in attachment anxiety and avoidance shape the variability in this normative reorganization process, largely as a result of the characteristic ways in which these styles organize emotion-regulatory tendencies. The paper closes with a series of integrative questions for future research, including a call for new studies aimed at understanding under what contexts anxiety and avoidance may be adaptive in promoting emotion recovery to separation and divorce experiences.

    In this work, the design of a control system with fuzzy PID controllers is reported. It combines the techniques of multimode control and gain scheduling as well as the design of a compensator that will reduce the interaction effects among control loops in a multivariable system. The simulated system is based on a non-lineal mathematical model. Its validity range supports up to 1440 watts, for a nominal design of 1 KW power. To carry out the fuzzy PID Controller's design, firstly the PID conventional controllers were designed for three operating points of power demand: 0 W, 500 W and 1000 W. The methodology adopted for the determination of the conventional PID controller's parameters was poles cancellation. This methodology demanded the lineal identification of the process for the three mentioned operating points: low, medium and high power. With the information obtained from the adjusted conventional controllers in the three operating points, the design of fuzzy PID controllers based on the TSK system was achieved. For this work, this method is equivalent to the technique of gain scheduling since only conventional PID controllers with the same structure are used. In addition, a control scheme using a compensator that had the function of reducing the interaction effects among the control loops was designed. The compensator was located between the controller and the plant and only introduces compensation factors among control signals, maintaining the direct path of the control loop in the original control scheme. Several tests of the whole operating range, in order to make a performance analysis of both the conventional PID controller and the fuzzy PID controller were carried out, introducing step form signals in the power demand. The performance of the generation system was validated as a function of an error based index minimization as well as on the actuator control signal shape. The dynamic coupling degree among the control loops was analyzed, as well

    In the Bajio region the underground water is the main source of drinking water and approximately constitutes 50% of the water used for agricultural purposes. From the energy standpoint pumping represents 33% of the electricity consumption and a wastage of 35% is estimated.

    In the Bajio region the underground water is the main source of drinking water and approximately constitutes 50% of the water used for agricultural purposes. From the energy standpoint pumping represents 33% of the electricity consumption and a wastage of 35% is estimated.

    A non-isolated DC-AC converter with high voltage gain with two output sinusoidal voltage - 110 V and 220 V - and frequency 60 Hz for application in autonomous systems of electric power is proposed in this work. This topology consists of a boost converter with high voltage gain, based on three-state switching cell combined with a double half bridge inverter. This configuration type the size and the cost are reduced and the efficiency is gotten better, due to the reduced number of switches. The converters that compose this topology operate with high frequency, reducing the volume of the magnetic materials. can be mention as important characteristics: the voltage stress across the switches of the boost converter are low, due they be naturally clamped by one output filter capacitor, which allows the utilization of switches with lower conduction resistances, and the waveforms of the output voltage of the double half bridge inverter supplies for the load it is sinusoidal and it possesses low harmonic content.

    Full Text Available The concept of the normative personal orientation seeks to specify how personnel motivation should be organized in the value-motivational sphere for professional activity execution in accordance with its social purpose. Based on the priority of the civil service social purpose, the hierarchical structure of the personal normative orientations was theoretically validated. Social motives related to serving for the benefit of the Fatherland as well as work motives associated with the achievement of some role positions are the major motives. The subordinate motives are the monetary rewards and self-development. Development of the future civil servants’ orientation is based on a conscious idea about the required motives’ subordination, that is, about the normative civil servant’s orientation. The study involved 63 students of the 2nd and 4th year studying at the Russian management institute in the specialty “Customs” and 51 students of the 1st and 2nd year studying at the Public Administration Academy of the Republic of Armenia, as well as 4 experts (two from Russia and Armenia having long-term experience in the civil service. The method is an author’s closed-questions’ inventory containing a list of 18 personal goals, that should guide the civil servant in professional work. The instruction required the selection of five most important goals. An absolute majority (from 66 to 90% of Russian and Armenian students has the motives’ subordination that is inconsistent with the normative orientation. According to the students’ view, self-development, self-creation and material benefit are the leading motives of a civil servant. The expert motives’ representations are identical to the required content of civil servant normative orientation. The authors defined the need to develop a special psychological and educational program for promoting required representations about the normative orientation of future civil servants.

    Numerous studies have demonstrated the existence and effect of normative misperceptions on heavy episodic drinking behavior. However, there has been little work on these processes or application of normative-belief interventions outside the U.S. college system. The aim of the current study, therefore, was to investigate heavy episodic drinking and normative misperceptions in a U.K. university setting. An email containing a link to a survey Web site was distributed to all current undergraduate students at the University of Paisley, Scotland. In addition to age and gender questions, the survey contained items on students' personal behavior and perception of the level of that behavior in three groups of increasing social distance: close friends, other students of the same age, and other people of the same age in U.K. society in general. Completed surveys from 500 respondents were returned. In keeping with previous research, significant correlations were found between the respondents' behavior and the perception of that behavior in others, with beliefs about the most proximal individuals being the most strongly correlated. The majority of respondents were also found to overestimate alcohol consumption in other students. An age effect was noted, in which misperceptions appeared to decrease with age but did not vary between genders. The findings of the study indicate that the normative-belief alcohol consumption processes that have been found on U.S. college campuses also operate in U.K. university settings. This raises the possibility of applying social-norms interventions from the United States to the United Kingdom and potentially elsewhere in the world. Furthermore, the study noted apparent age effects in the degree of misperception, the implications of which are discussed.

  12. Eye-tracking measurements and their link to a normative model of monitoring behaviour.

    Increasing automation necessitates operators monitoring appropriately (OMA) and raises the question of how to identify them in future selections. A normative model was developed providing criteria for the identification of OMA. According to this model, the monitoring process comprises distinct monitoring phases (orientation, anticipation, detection and recheck) in which attention should be focused on relevant areas. The current study tests the normative model on the basis of eye tracking. The eye-tracking data revealed increased concentration on relevant areas during the orientation and anticipation phase in comparison to the other phases. For the assessment of monitoring behaviour in the context of personnel selection, this implies that the anticipation and orientation phases should be considered separately as they appear to be more important in the context of monitoring than the other phases. A normative model was developed for the assessment of monitoring behaviour. Using the eye-tracking method, this model was tested with applicants for an Air Traffic Controller training programme. The results are relevant for the future selection of human operators, who will have to monitor highly automated systems.

The requirements established in standards IAEA GS-R-3, IAEA GS-G-3.1, IAEA DS 349, NBR ISO 9001:2000 e CNEN-NN-1.16 are critically analyzed. A correlation matrix of the applicable standards is presented and the related topics among them are identified. The standards IAEA GS-R-3, IAEA GS-G-3.1 and IAEA DS 349 define general requirements for establishing, implementing, assessing and continually improving an integrated management system in nuclear installations and activities, in IAEA member countries. The standard NBR ISO 9001:2000 establishes general requirements for the implementation of a quality management system in all kinds of organizations. The standard CNEN NN-1.16 establishes the regulating requirements for the quality assurance systems and programs of nuclear installations, for licensing and authorization for operation of these installations in Brazil. The standard IAEA GS-R-3 that replaces the code IAEA 50-C-Q introduces the concept of 'Integrated Management System' for the nuclear area, in preference to the concepts of 'Quality Assurance' and 'Quality Management'. This new approach is aligned with the current tendency incorporating requirements of quality, safety, health, environment, security, economics and other in a unique management system. Examples of quality management systems implemented by Brazilian nuclear organizations and by nuclear organizations outside Brazil are analyzed and considered in the discussion of results. (author)

    Full Text Available The adoption of the principle of the Responsibility to Protect (RtoP by all United Nations General Assembly (UNGA member states in 2005, and its reaffirmation in dozens of United Nations Security Council (UNSC resolutions, indicate that there is a growing consensus around the world that egregious human rights violations necessitate a cooperative and decisive international response. But just as the political debates raged surrounding the precise articulation of RtoP between 2001 and 2005, so too goes the contemporary debate surrounding the implementation of RtoP. Regional divergences in RtoP implementation, in particular, have been noted by many scholars, as regional organizations implement those elements of RtoP that best suit their policy goals. This paper will apply recent scholarship on norm-lifecycles, specifically on “norm localization” to the operationalization of RtoP by regional organizations. We seek to explore regional divergences on RtoP implementation between the European Union (EU, League of Arab States (LAS, and the African Union (AU on Libya and Syria. From this assessment, three main arguments will be put forward: (1 regional organizations remain politicized, reframing RtoP in divergent ways that dilute the strength of the norm, (2 politicization of the RtoP discourse constrains regional norm localization processes, (3 politicization and reframing of RtoP inhibit regional normative change and limit the potential for timely and decisive responses to protect civilians.

    Full Text Available A geração de energia elétrica no Brasil é predominantemente renovável, com a geração interna hidráulica sendo superior a 74% do total de sua matriz energética. O racionamento de energia elétrica ocorrido em 2001, devido à falta de chuvas, levou o país a incrementar a participação de fontes alternativas de energia. Esta necessidade por novas fontes de energia faz com que as potencialidades regionais sejam aproveitadas, o que configura a mudança do modelo de geração, passando de geração centralizada para geração distribuída. Dentre as fontes alternativas de energia, a solar apresenta-se como uma fonte bastante promissora para o Brasil, tendo em vista que a maior parte do seu território está localizada próximo à linha do equador, o que acarreta em um dia de maior duração solar. O Rio Grande do Norte (RN tem um dos maiores índices de incidência solar do território brasileiro, o que o torna apto a receber investimentos para a instalação de usinas solares fotovoltaicas.

    Full Text Available O pós-Guerra Fria (1991-2006 apresenta uma mudança significativa no cenário estratégico: a maior acessibilidade da tecnologia militar e o surgimento de novas armas capazes de modificar o poder coercitivo dos países - como as armas de energia direta - acabam pondo em xeque a ideia de que a primazia nuclear é condição suficiente para garantir a unipolaridade. Focando-se no atual recrudescimento das tensões entre EUA e Rússia - especialmente com a proposta norte-americana de implementação do Escudo Antimíssil no Leste Europeu - e analisando as relações de poder entre os três países, procuramos revelar que tipo de competição ocorrerá no sistema internacional nas próximas décadas. O presente artigo analisa as reais possibilidades de que a primazia nuclear norte-americana se torne efetiva, uma vez que, para tanto, é necessário o desarmamento estratégico das demais potências. Como uma guerra nuclear entre os três países possui um custo político muito elevado, as disputas tendem a ser decididas na esfera das operações. Para ilustrar esta última afirmação, usamos um cenário contrafactual de guerra nuclear limitada entre Estados Unidos, Rússia e China, por meio do qual tentamos evidenciar as precondições táticas e operacionais para uma eventual vitória da coalizão sino-russa.The evolution of the Post-Cold War (1991-2006 international system shows a significant amount of change regarding the strategic capabilities of United States, Russia, and China.

    Since 1997 the Secretaria de Energia (SENER) publishes an annual report named Prospectiva del Sector Electrico, in which detailed information on the situation of the Mexican electrical sector is included, the information is related to the technological, economic and environmental aspects of all the organisms involved in the matter of electrical energy, within which stand out the Comision Federal de Electricidad (CFE), Luz y Fuerza del Centro (LyFC), the Comision Reguladora de Energia (CRE) and the Comision Nacional para el Ahorro de Energia (CONAE). In the prospectives the tendency of the modifications that will undergo the sector in a period of 10 years is analyzed. All the prospectives of the electrical sector, agree in that the growth of this sector is determined by the construction of power stations that use natural gas as primary energy, reason why we made an analysis of the prospectives of the natural gas market, with the purpose of observing the interaction between both sectors. At the moment seven prospectives of each sector have been published, given the conditions at the moment of their publication, they present differences and agreements between each other for periods of intersection. The present work shows the comparison between the expectations of growth reported by each one of the Prospectives.

    2017-04-01

    Normative messages have been shown to increase intention to do physical activity. We traced how "positive" and "negative" normative messages influenced physical activity intention by comparing constructs of the model of goal-directed behavior with descriptive norms (MGDB + DNs) across control and treatment groups in an experiment. For this purpose, 16-24-year-old respondents (n = 1,200) in Bulgaria, Croatia, and Romania were asked about their age, sex, and levels of physical activity before being exposed to positive and negative normative messages and completing a questionnaire with MGDB + DNs scales. Different MGDB + DNs constructs were influenced by the normative messages: compared with the control, the negative message group showed stronger attitudes (p = .003) and the positive message group showed higher positive anticipated emotions (p = .005). The positive message's effect is consistent with the literature on conformity to social norms. The negative message's effect lends itself to interpretations based on social identity and deviance regulation theories.

    2015-01-01

    Background: Measurement of for near point of convergence (NPC), amplitude of accommodation (AA) and phoria are important components of diagnosing nonstrabismic binocular vision anomalies. There is a huge variation in the normative data established for orthoptic parameters because of the variation in measurement technique. There are only limited studies for normative data based on nonclinical population in Indian population. Therefore, we aim estimate the normative values for NPC, AA, and phoria measurement in Indian population using techniques, which has good repeatability and reliability. Materials and Methods: Subjects between the age group 10-35 years participated in this prospective cross-sectional study. A self-administered symptom questionnaire was used to exclude patients with asthenopic symptoms. Clinical techniques which have good repeatability and reliability were used. NPC was measured using pen light red, green glass test. AA was measured using minus lens technique. Horizontal and vertical phoria at distance and near was measured using modified Thorington method. Results: One hundred and fifty subjects participated in the study. We found that NPC receded with age, which could because of the increase in horizontal phoria at near with age. The mean normative value for objective NPC, break and recovery of subjective NPC, monocular and binocular AA, horizontal and vertical phoria at distance and near for the three age groups are reported in the study. Conclusion: The data presented in this study can be used as a cut-off by eye care practitioners while diagnosing convergence, accommodation related anomalies in Indian population. PMID:25709268

    Mundy, Lily R.; Homa, Karen; Klassen, Anne F.; Pusic, Andrea L.; Kerrigan, Carolyn L.

    2016-01-01

    Background The BREAST-Q is a rigorously developed, well-validated, patient-reported outcome (PRO) instrument with a module designed for evaluating breast augmentation outcomes. However, there are no published normative BREAST-Q scores, limiting interpretation. Methods Normative data were generated for the BREAST-Q Augmentation Module via the Army of Women (AOW), an online community of women (with and without breast cancer) engaged in breast-cancer related research. Members were recruited via email, with women 18 years or older without a history of breast cancer or breast surgery invited to participate. Descriptive statistics and a linear multivariate regression were performed. A separate analysis compared normative scores to findings from previously published BREAST-Q augmentation studies. Results The preoperative BREAST-Q Augmentation Module was completed by 1,211 women. Mean age was 54 ±24 years, mean body mass index (BMI) was 27 ±6, and 39% (n=467) had a bra cup size ≥D. Mean scores were Satisfaction with Breasts (54 ±19), Psychosocial Well-being (66 ±20), Sexual Well-being (49 ±20), and Physical Well-being (86 ±15). Women with a BMI of 30 or greater and bra cup size D or greater had lower scores. In comparison to AOW scores, published BREAST-Q augmentation scores were lower before and higher after surgery for all scales except Physical Well-being. Conclusions The AOW normative data represent breast-related satisfaction and well-being in woman not actively seeking breast augmentation. This data may be used as normative comparison values for those seeking and undergoing surgery as we did, demonstrating the value of breast augmentation in this patient population. PMID:28350657

  16. Accounting - a Normative Representation of Economic Reality?

    Directory of Open Access Journals (Sweden)

    Gianina Roman

    2010-07-01

    Full Text Available Accounting is currently a very dynamic field at international level. Accounting information or its derivatives comprise an important segment of the information conveyed in the economic environment. Therefore, accounting is considered by some authors as the most important information source of a nation. Widening and diversifying the request for information from the scope of financial accounting is generated by modernization and restructuring economy and society development as a whole. In these circumstances, accounting has a very important role. Establishing decision based on a real, pertinent, relevant, timely information system insures a performance administration, management of the current situation, with many phenomena of crisis. Accounting involves the perception of real which is based on a conceptual system, which means that the entire accounting system is based on a set of objectives, postulates, principles, rules and regulations. When different objects are placed in different areas, the differentiation between real and ideal is only formal.

    Tools and criteria for the Cost-Benefit analysis from the energy saving in bioclimatic designs (BD) are presented, for which, a reference project is established and the costs and benefits of energy saving in BD with base in that project are evaluated. A case study is presented taking as reference the traditional design of the air conditioning of a building and with this base the estimation of cost-benefit of the same building is made, but with passive systems. The tools used are those that allow to consider related resources such as time and money; in that sense, are used criteria such as: Present value (PV), Equivalent Annual Cost (EAC) and the Cost of the Conserved Energy (CCE). The costs related to the construction, maintenance and operation of the design are taken into account. The differences between the reference design and the BD, established from the application of these criteria, allow to evaluate the economic margin of the BD as far as operation and maintenance is concerned. Finally the CCE of the bioclimatic measures is evaluated as an initiative of energy saving and the present value is calculated of the energy saving in the entire useful life of a bioclimatic design.

    Ferguson, Eamonn; Lawrence, Claire

    2013-05-01

    There is increasing use of counter-normative health messages (i.e., evidence-based health information about cause-effect relationships that run counter to shared normative beliefs, e.g., stress can lead to personal growth). The current studies examine the effect of normative and counter-normative messages about stress on levels of symptom reporting. Predictions are derived from reactance, social comparison, and self-enhancement theories. Two studies focus on the development of the messages, and two experimental studies examine the effect of manipulating normative and counter-normative messages on symptom reports. The final study controls for mere-measurement effects and explores the role of stress process variables (appraisals and coping). Exposure to a normative message (stress causes ill health) results in reduced symptom reporting compared to a counter-normative message (stress provides challenge, growth, and development) and control groups. The results suggest that people may use symptom reporting strategically to indicate coping. Based on the argument that beliefs about stress and health are stored as mental models, the theoretical associations derived from stress theory are only observed when a normative message is presented. Counter-normative stress messages may carry no tangible benefits compared to normative messages. Some stress research may suffer from inherent methodological bias when normative information is provided in information and consent sheets. Statement of contribution What is already known on this subject? At present, nothing is known about counter-normative health messages, despite the fact that they are becoming widely used as a public intervention. What does this study add? A clear operational definition of counter-normative messages. A test of three competing theories for counter-normative messages that focus of the stress-symptom link. Demonstrating for the first time, that in the domain of stress and health, counter-normative messages

  5. The normative structure of mathematization in systematic biology.

    Science.gov (United States)

    Sterner, Beckett; Lidgard, Scott

    2014-06-01

    We argue that the mathematization of science should be understood as a normative activity of advocating for a particular methodology with its own criteria for evaluating good research. As a case study, we examine the mathematization of taxonomic classification in systematic biology. We show how mathematization is a normative activity by contrasting its distinctive features in numerical taxonomy in the 1960s with an earlier reform advocated by Ernst Mayr starting in the 1940s. Both Mayr and the numerical taxonomists sought to formalize the work of classification, but Mayr introduced a qualitative formalism based on human judgment for determining the taxonomic rank of populations, while the numerical taxonomists introduced a quantitative formalism based on automated procedures for computing classifications. The key contrast between Mayr and the numerical taxonomists is how they conceptualized the temporal structure of the workflow of classification, specifically where they allowed meta-level discourse about difficulties in producing the classification.

  6. Practical Intersubjectivity and Normative Guidance: Bratman on Shared Agency

    Directory of Open Access Journals (Sweden)

    Roth Abraham Sesshu

    2015-01-01

    Full Text Available In an important new book on shared agency, Michael Bratman develops an account of the normative demand for the coordination of intentions amongst participants in shared agency. Bratman seeks to understand this form of normative guidance in terms of that associated with individual planning intentions. I give reasons to resist his form of reductionism. In addition, I note how Bratman’s discussion raises the interesting issue of the function or purpose of shared intention and of shared agency more generally. According to Bratman, the function of shared intention is to promote interpersonal coordination of intention and action.

    Cratsley, Kelso

    2015-01-01

    Given that the concept of coercion remains a central concern for bioethics, Quigley's (Monash Bioethics Rev 32:141-158, 2014) recent article provides a helpful analysis of its frequent misapplication in debates over the use of 'nudges'. In this commentary I present a generally sympathetic response to Quigley's argument while also raising several issues that are important for the larger debates about nudges and coercion. I focus on several closely related topics, including the definition of coercion, the role of empirical research, and the normative concerns at the core of these disputes. I suggest that while a degree of precision is certainly required when deploying the relevant concepts, perhaps informed by empirical data, we need to continue to push these debates towards more pressing normative considerations.

  8. Normative, gain and hedonic goal frames guiding environmental behavior

    OpenAIRE

    Lindenberg, Siegwart; Steg, Linda

    2007-01-01

    This article discusses new developments about goal-dependent framing and multiple goal frames (sometimes also called "multiple motives"), which are highly relevant for understanding environmental behavior. We introduce goal-framing theory, which postulates that goals "frame" the way people process information and act upon it. Three goal frames are distinguished: a hedonic, gain, and normative goal frame. In general, multiple goals are active at any given time, which may (or may not) be compat...

    This paper proposes a framework to balance considerations of welfarism and virtue ethics in the normative analysis of economic models with endogenous preferences. We introduce the moral evaluation function (MEF), which ranks alternatives based purely on virtue ethics, and define the social objective function (SOF), which combines the Social Welfare Function (SWF) and the MEF. In a model of intergenerational altruism with endogenous time preference, using numerical simulations we show that max...

    Neuromoral theorists are those who claim that a scientific understanding of moral judgment through the methods of psychology, neuroscience and related disciplines can have normative implications and can be used to improve the human ability to make moral judgments. We consider three neuromoral theories: one suggested by Gazzaniga, one put forward by Gigerenzer, and one developed by Greene. By contrasting these theories we reveal some of the fundamental issues that neuromoral theories in genera...

    What is the connection between reasons and motives? According to Reasons Internalism there is a non-trivial conceptual connection between normative reasons and the possibility of rationally accessing relevant motivation. Reasons Internalism is attractive insofar as it captures the thought that reasons are for reasoning with and repulsive insofar as it fails to generate sufficient critical distance between reasons and motives. Rather than directly adjudicate this dispute, I extract from it two...

    Autonomous agents operating in a dynamic environment must be able to reason about their actions in pursuit of their goals. An additional consideration for such agents is that their actions may be constrained by norms that aim at defining an acceptable behaviour for the agents. The inclusion of normative reasoning into practical reasoning is derived from the necessity for effective mechanisms that regulate an agent’s behaviour in an open environment without compromising their autonomy. However...

    2017-02-01

    Full Text Available The article investigates the reproductive normativity in the context of its relationship to person’s psychological well-being. The theoretical analysis allowed to formulate the definition of reproductive normativity (RN and its structural components. It’s considered the problem of relation between objective and subjective components of RN as the determinant of psychological well-being. It’s presented and justified one of the possible typologies of RN, reflecting the most common variants of modern Russians’ reproductive behavior: 1 high RN («The total normativity»; 2 medium-high RN («Family with deviant past»; 3 medium-low RN («Single parenthood»; 4 low RN («No family and children». The presence of different relations between objective and subjective components of RN in described types is empirically detected. The highest consistency of RN components is observed in groups with high and low RN, the lowest consistency is manifested among single parents. The mismatch between RN components is associated with lower psychological well-being. Single parents are at risk: they demonstrate the most negative evaluations of their life, self-awareness and self-attitude. Average- auspicious and almost identical indicators of psychological well-being were found among respondents with deviant past (medium-high RN and respondents with no family and children (low RN: psychological benefits of having family and children are eliminated by abnormal parenthood experience and by the mismatch between desired and actual implementation of family life. Thereby the «blocked» parent role is connected with the same level of psychological well-being as the improperly played parent role. The highest level of psychological well-being is expectedly found among respondents with high RN («The total normativity».

    The interaction between political executives and civil servants rests on a delicate balance between political responsiveness and the duty of civil servants and ministers to respect legal and other normative constraints on executive authority. In Danish central government, this balance is stressed...... by norms that define the correct behavior when the civil service provides ministers with political advice and assistance. Organizational factors strongly influence civil servants’ behavior when they have to balance responsiveness against constraints on their role as political advisers. Moreover, civil...

    2016-11-01

    The Lower Quarter Y Balance (YBT-LQ) Test performance varies depending on competitive level, sport, gender, and age; therefore, determining normative scores specific to a population may be helpful in identifying injury-risk thresholds and return-to-play criteria following an injury. The purpose of this study was to determine normative YBT-LQ scores by assessing a subset of female, Division I volleyball players. A descriptive analysis cohort study. Ninety healthy (19.6 ± 1.2 y/o), collegiate female volleyball players. YBT-LQ was measured in 3 distinct directions of anterior (ANT), posteromedial (PM) and posterolateral (PL) on both the dominant and non-dominant limbs. In addition, a one way ANOVA was performed to determine mean group differences of YBT-LQ dominant and non-dominant limb composite score across position. Baseline values for this population were 94.1 ± 6.6% on the dominant limb and 93.9 ± 6.2% on the non-dominant limb. There were no significant differences for YBT-LQ composite scores on dominant (P = 0.867) and non-dominant (P = 0.989) limbs between position. This study identified normative YBT-LQ composite scores for healthy, female, collegiate volleyball players. Participants performed similarly despite their position. Copyright © 2016 Elsevier Ltd.

  20. Hungers that Need Feeding: On the Normativity of Mindful Nourishment.

    Science.gov (United States)

    Vogel, Else

    2017-08-01

    Drawing on participant observation in a 'mindful weight loss' course offered in the Netherlands, this paper explores the normative register through which mindfulness techniques cast people in relation to concerns with overeating and body weight. The women seeking out mindfulness use eating to cope with troubles in their lives and are hindered by a preoccupation with the size of their bodies. Mindfulness coaches aim to help them let go of this 'struggle with eating' by posing as the central question: 'what do I really hunger after?' The self's hungers include 'belly hunger' but also stem from mouths, hearts, heads, noses and eyes. They cannot all be fed by food. The techniques detailed in this paper focus on recognizing and disentangling one's hungers; developing self-knowledge of and a sensitivity to what 'feeds' one's life; and the way one positions oneself in relation to oneself and the world. While introducing new norms, the course configures 'goods' and 'bads' in different ways altogether, shaping the worlds people come to inhabit through engaging in self-care. In particular, the hungering body is foregrounded as the medium through which life is lived. Taking a material semiotic approach, this paper makes an intervention by articulating the normative register of nourishment in contrast to normalization. Thus, it highlights anthropologists' potential strengthening of different ways of doing normativity.

  1. Practicing vaginistic femininity: Doing bodies, enacting normative heterosexuality

    Directory of Open Access Journals (Sweden)

    Stephanie Stelko

    2015-12-01

    Full Text Available Vaginismus is a female sexual pain disorder, characterized by contractions of the pubococcygeus (PC muscle that surrounds the outer third of the vagina, which makes penetrative penile-vaginal intercourse (coitus, insertion of a finger or tampon and gynecological examinations hard or impossible, and painful for the woman. The condition is believed to be associated with negative beliefs, attitudes or experiences related to sex. Vaginismus has important social repercussions in everyday life, which acquire meaning in the context of hegemonic heterosexuality. In line with theories of performativity, heterosexuality and gender are normatively and performatively linked sets of practices, with coitus being the central practice of heterosexuality and thus defining for one’s gender. Thus, the inability of vaginistic women to perform coitus impairs their performance of normative heterogender. In this article I address gender experiences of women with primary vaginismus, by looking at social and bodily practices they engage in. In the first part of the article, I explore how women with primary vaginismus do (vaginistic heterogender. In the second part I address the practices they do in order to ‘overcome’ vaginismus, thus improving their performance of normative heterogender, and argue that these practices are gendering themselves.

    2015-03-01

    Women with a gambling problem bear a negative social stigma. Based on the theory of symbolic interactionism, this study examined the construction of social identities by 17 Israeli women diagnosed with a gambling disorder. Interpretive interactionist analysis revealed how they construct their identity through correspondence with patterns of behavior that are perceived as normative, and identified 3 major themes: "I'm not actually a gambler" (the presentation of a multidimensional identity comprising other identities besides that of a gambler); "Staying normative during gambling"; and "I have changed" (reformed gamblers' presentation of themselves as having changed for the better). The findings underscore the complex dialogue behind the identity construction put forward by women with a gambling problem, their yearning to be perceived by society as normative women and to fit in despite their stigmatized behavior, and the tension they feel in society's relationship toward them. The findings also suggest that practitioners who work with women gamblers may want to pay attention to the power relations shaping identity construction in an interview setting, and look more closely at the women's awareness of the stigma they bear and the complex processes that make up their multidimensional identity.

    Full Text Available ABSTRACT Objective: The aim of the present study was to define normative data of phrenic nerve conduction parameters of a healthy population. Methods: Phrenic nerve conduction studies were performed in 27 healthy volunteers. Results: The normative limits for expiratory phrenic nerve compound muscle action potential were: amplitude (0.47 mv - 0.83 mv, latency (5.74 ms - 7.10 ms, area (6.20 ms/mv - 7.20 ms/mv and duration (18.30 ms - 20.96 ms. Inspiratory normative limits were: amplitude (0.67 mv - 1.11 mv, latency (5.90 ms - 6.34 ms, area (5.62 ms/mv - 6.72 ms/mv and duration (13.77 ms - 15.37 ms. Conclusion: The best point of phrenic nerve stimulus in the neck varies among individuals between the medial and lateral border of the clavicular head of the sternocleidomastoid muscle and stimulation of both sites, then choosing the best phrenic nerve response, seems to be the appropriate procedure.

    2017-12-01

    The Remote Associates Test (RAT) is a well-known measure of creativity, with each item on the RAT is composed of three unrelated stimulus words. The participant's task is to find an answer in the form of a word that could combine with each of the stimulus words, thus forming three new actual nouns. Researchers have modified the RAT to develop compound remote associate problems that emphasize combining vocabulary to form compound words. In the field of creativity research for Mandarin speakers, the Chinese RAT has been widely applied for over 10 years. The original RAT, compound remote associate problems, and Chinese RAT have various common advantages, such as being convenient to use and having objective scoring; additionally, the development of items for certain tests is easy and satisfies the requirements of psychological assessments in terms of the quantity of items. Currently, many language editions of the RAT and compound remote associate problems already exist. In particular, the English and Italian versions of these tests already have derived normative data. Because approximately 20% of the world's population are native Mandarin speakers, and because increasing numbers of people are choosing Mandarin as a second language, the need to increase Mandarin-language resources is growing; however, normative data for the Chinese RAT still do not exist. To address this issue, in the present study we developed Chinese compound remote associate problems and analyzed the passing rates by items, problem solving times, and various normative data, using the responses of 253 subjects in three experiments.

    College students in the U.S. continue to drink in hazardous ways and experience a range of alcohol-related consequences. Personalized feedback interventions (PFIs), which often include normative components comparing personal drinking to that of similar peers, have been effective in reducing alcohol outcomes among college students. Though normative perceptions of the quantity and frequency of alcohol use have been examined in many studies, norms for alcohol-related consequences have received less attention. The current study examined self-other discrepancies (SODs) for alcohol-related consequences among college students. Participants overestimated how often alcohol-related consequences are experienced by other same-sex students on campus and rated consequences as more acceptable for others to experience than themselves. No differences in SODs were found between those who did and did not report alcohol use. Future studies should examine the efficacy of PFIs that incorporate normative feedback on alcohol-related consequences. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Optimized derived limits (ODL) for gaseous and liquid wastes released to the environment of Instituto de Energia Atomica (IEA) following the ICRP's recommendations were determined. Techniques for routine environmental monitoring were implanted in order to ensure that these limits be respected. The treatment of liquid wastes which gives rise to the optimized discharge resulted from cost-benefit analysis, is the elimination of medium half-lived radioisotopes in the soil. The ODL value for iodine-131 is 50mCi/y and 7,5 Ci/y for gaseous and liquid effluents, respectively. The ODL values for other radionuclides of radiosanitary interest in liquid waste also determined. The most appropriate environmental monitoring techniques for IEA were studied and parameters of radioactive material dilution in the atmosphere and water courses were determined. Sample collection points were chosen to obtain the most representative data for the evaluation of radioactive dose in the critical group and the detriment produced in the population. Detection system and methods were calibrated and standardized for the determination of radionuclides in wastes released from IEA in order to evaluate their concentrations in the main transference pathways.

    2009-01-01

    This study examined the contribution of general normative beliefs about aggression and specific normative beliefs about retaliatory aggression in predicting physical, verbal, and indirect aggressive behaviors. Two hundred and forty-nine Grade 4 and Grade 5 boys completed the Normative Beliefs about Aggression Scale (NOBAGS) and provided self-reports on the frequency of their physical, verbal, and indirect aggressive behaviors. A series of hierarchical multiple regression analyses revealed that general normative beliefs about aggression contributed significantly in predicting all three types of aggressive behaviors. When general normative beliefs about aggression were controlled for, specific normative beliefs about retaliatory aggression against males but not specific normative beliefs about retaliatory aggression against females, contributed significantly to predict physical, verbal, and indirect aggressive behaviors. Implications for intervention programs are discussed.

    To determine normative values for pattern-reversal electroretinogram (PERG) in healthy adult volunteers according to the standard protocol recommended by the International Society for Clinical Electrophysiology of Vision-ISCEV. Participants were 30 healthy volunteers (15 males) with ages from 18 to 61 years (mean= 30.8 +/- 8.7 yrs.; median= 29.5 yrs). Inclusion criteria were: visual acuity of 0.0 logMAR (20/20 Snellen) in each eye, absence of visual complaints, absence of media opacities, negative history for ocular or neurological diseases, negative family history for ocular and informed consent. PERG was recorded from each eye in a darkened room at 1 m from a high resolution display monitor. Stimuli were monochromatic checkerboards subtending 60, 15 e 7.5 minutes of visual angle reversing at 1.9 Hz. Responses were obtained from modified disposable fiber electrodes developed at UNIFESP. Latency (ms) for N35, P50 and N95 components as well as peak-to-peak amplitudes (microV) for N35-P50 and P50-N95 were determined. For normative values only one randomly chosen eye was included. Normal limits were calculated as 97.5% percentiles for latency and 2.5% percentile for amplitudes for each stimulus size. Normal limits for N35, P50 and N95 latencies for 60', 15' and 7.5' stimuli were respectively: N35 - 40.1; 39.9 and 41.3 ms; P50 - 60.5; 64.4 and 65.6 ms and N95 - 103.4; 104.6 and 104.6 ms. For amplitude the normative values for N35-P50 and P50-N95 for 60', 15' and 7.5' were respectively: N35-P50 - 1.7; 1.6 and 0.9 microV; P50-N95 - 3.8; 2.8 and 1.5 microV. No gender differences were found either for latency or for amplitude in the three stimulus sizes. There was no correlation between PERG latency and amplitude with age, except for P50 amplitude for stimulus 15'(r=0.39; P=0.035). Normative values were determined for PERG parameters of amplitude and latency for three stimulus sizes. These parameters are important for evaluating the normal functioning of retinal ganglion

Nevertheless, since the use of the nuclear energy began to descend ago more of 25 years, it is has speculated continually about the possible nuclear rebirth. Are such predictions based in solid basis or are mere groundless prognostics? The objective of the present document is to analyze the economic aspects of the nuclear energy, to identify the key factors that they allow to determine its competitiveness and to sound the possible markets for the new plants of nuclear energy. To achieve this, it is divided in the following sections: Revision of the current state of the nuclear energy, including the location, the type and capacity of the plants; Identification of the variables that determine the economic situation of the nuclear energy; Revision of the recent predictions and of the economic aspects of the Olkiluoto nuclear power plant of Finland; A revision by market of the possible future of the new nuclear facilities in the coming decade.

    The actions for the energy efficiency and the utilization of renewable energies are multiple and dispersed, in each one of the energy consumption points of the country. For this reason, two important factors to foment these actions are to promote the social participation and the effective government communication towards the society: energy saving and social participation. One of the main faculties of the National Commission of Energy Saving (CONAE) is to foment the efficiency in the energy use, through actions coordinated with the different agencies and organizations of the Federal Public Administration, with the governments of the federal entities and the municipalities and, through coordinated operations, with the private and social sectors. The CONAE has established mechanisms of coordination and cooperation with the private and social sectors, having fomented programs, projects and actions whose purpose is the energy efficiency, outstanding: 1) Committees and work groups; 2) Cooperation Agreements; 3) the Advisory Council for the Foment of Renewable Energy.

    Full Text Available Este artigo tem por objetivo verificar como as ações do sistema setorial brasileiro de energia eólica se relacionam com as perspectivas econômicas, sociais e ambientais que caracterizam inovações sustentáveis. Argumenta que as questões energéticas estão no cerne do desenvolvimento humano ao longo de sua história e que, em decorrência do atual cenário de mudanças climáticas, o desenvolvimento de fontes alternativas de energia é de vital importância na contemporaneidade. Metodologicamente, o estudo pode ser considerado exploratório e descritivo em relação aos fins e bibliográfico no que diz respeito aos meios. Foram utilizados dados primários de agências nacionais, regionais e mundiais de energia eólica para aumentar a consistência das informações coletadas e do trabalho como um todo. Os resultados evidenciam que o sistema setorial de energia eólica está estruturado em torno de uma série de instituições públicas, autarquias, associações de pesquisa e outros stakeholders que demonstram crescente interesse no desenvolvimento do setor no país. Os dados indicam, ainda, que os valores alcançados ao longo dos últimos leilões de energia eólica têm evidenciado o potencial de competitividade dessa fonte energética em comparação com as demais. Conclusivamente, é possível verificar que os pilares da sustentabilidade podem ser visualizados ao longo de praticamente todas as questões envolvendo a implantação de novas usinas eólicas, mas que a dimensão econômica ainda é a de maior destaque, tornando as dimensões sociais e ambientais dependentes da capacidade dessa modalidade de energia competir com outras.

  4. Normative ethics does not need a foundation: it needs more science.

    The impact of science on ethics forms since long the subject of intense debate. Although there is a growing consensus that science can describe morality and explain its evolutionary origins, there is less consensus about the ability of science to provide input to the normative domain of ethics. Whereas defenders of a scientific normative ethics appeal to naturalism, its critics either see the naturalistic fallacy committed or argue that the relevance of science to normative ethics remains undemonstrated. In this paper, we argue that current scientific normative ethicists commit no fallacy, that criticisms of scientific ethics contradict each other, and that scientific insights are relevant to normative inquiries by informing ethics about the options open to the ethical debate. Moreover, when conceiving normative ethics as being a nonfoundational ethics, science can be used to evaluate every possible norm. This stands in contrast to foundational ethics in which some norms remain beyond scientific inquiry. Finally, we state that a difference in conception of normative ethics underlies the disagreement between proponents and opponents of a scientific ethics. Our argument is based on and preceded by a reconsideration of the notions naturalistic fallacy and foundational ethics. This argument differs from previous work in scientific ethics: whereas before the philosophical project of naturalizing the normative has been stressed, here we focus on concrete consequences of biological findings for normative decisions or on the day-to-day normative relevance of these scientific insights.

    To identify different components of smoking normative beliefs and determine if each component is independently associated with 2 clinically relevant measures of smoking in adolescents. Cross-sectional survey. One large suburban high school. A total of 1211 high school students aged 14 to 18 years. Current smoking and susceptibility to smoking. Of the 1138 students with data on current smoking, 216 (19.0%) reported current smoking, and 342 (38.3%) of the 893 nonsmoking students with susceptibility data were susceptible to future smoking. Factor analysis identified 3 normative belief constructs, labeled "perceived prevalence of smoking," "perceived popularity of smoking among elite/successful elements of society," and "disapproval of smoking by parents/peers." On average, students believed that 56% of people in the United States smoke cigarettes; 27.7% believed that wealthy people smoke more than poor people. Multiple logistic regression showed that each of the 3 constructs was independently associated with current smoking (adjusted odds ratios, 1.05 [95% confidence interval {CI}, 1.02-1.08], 1.12 [95% CI, 1.02-1.23], and 0.66 [95% CI, 0.59-0.75], respectively), even after controlling for covariates. Students' perceptions of smoking among the successful/elite and disapproval by parents/peers were independently associated with susceptibility to future smoking (adjusted odds ratios, 1.20 [95% CI, 1.11-1.29] and 0.87 [95% CI, 0.79-0.96], respectively). Adolescents' normative beliefs about smoking are multidimensional and include at least 3 distinct components, each of which was independently related to smoking outcomes. These distinct components should be considered in the design and evaluation of programs related to prevention and cessation of adolescent smoking.

  6. Normal or abnormal? 'Normative uncertainty' in psychiatric practice.

    The 'multicultural clinical interaction' presents itself as a dilemma for the mental health practitioner. Literature describes two problematic areas where this issues emerges--how to make an adequate distinction between religious rituals and the rituals that may be symptomatic of 'obsessive compulsive disorder' (OCD), and how to differentiate 'normative' religious or spiritual beliefs, behaviours, and experiences from 'psychotic' illnesses. When it comes to understanding service user's 'idioms of distress', beliefs about how culture influences behaviour can create considerable confusion and 'normative uncertainty' for mental health practitioners. In the absence of clear diagnostic and assessment criteria on distinguishing between 'culture' and 'psychopathology', practitioners have had to rely on their own intuition and seek out possible 'strategies' or 'procedures' from a contradictory and cross-disciplinary evidence base. Decontextualisation of service users' experiences may result in the pathologisation of culturally 'normative' phenomenon, 'category fallacy' errors, and poor health care experiences and outcomes for service users.This paper situates this dilemma within a wider debate that has concerned both the biomedical and social sciences, namely, the unresolved question of 'normality' or 'abnormality'. Indeed, issues that arise from dilemmas surrounding the question of 'culture' or 'psychopathology' are intimately tied to wider cultural ideas about what is considered 'normal'. The disciplines of psychiatry, psychology, and medical anthropology have struggled to establish workable criteria against which to judge behaviour as 'normal', 'abnormal', or 'pathological'. Three models for understanding mental 'abnormality' are evident in 'transcultural psychiatry' (what is now commonly known as 'cultural psychiatry'), and these models have corresponded closely to the interpretive models used by anthropologists attempting to make sense of the apparent diversity of

    Balance assessment plays an important role in occupational medicine. The diagnosis of patients with balance disturbances is based on a number of laboratory tests, including rotational chair tests, one of the most important. The normative value of kinetic tests greatly depends on movement parameters and laboratory equipment, which vary between diagnostic centers. The aim of the presented paper was to establish normatives for our laboratory and testing methodology in a group of healthy persons. The balance examination included 45 healthy persons (21 women and 24 men) aged 20-63 years (mean 38.5 +/- 14.9). The study population underwent very thorough neuro-otological examination, static posturography and VNG tests. The caloric test result was a crucial criterion for inclusion to the group of healthy persons. Rotational tests included: one "burst" test analyzing vestibulo-ocular reflex (VOR) with and without optokinetic stimulation visual vestibular optokinetic reflex (VVOR) and cervico-ocular reflex (COR); three impulse tests and sinusoidal harmonic rotation tests of 0.04, 0.08, 0.1, 0.16, 0.32, and 0.64 Hz. The mean values were: VVOR, 0.9 +/- 0.1; VOR, 0.5 +/- 0.1; and COR, 0.2 +/- 0.1. The mean value of rotational and post-rotational nystagmus induced by sudden chair stop (impulse stimulus) was 9 +/- 7 s, the gain values were 0.4 for sinusoidal tests, in the stimulation range of 0.1-0.32 and 0.5 for 0.64 Hz stimulation. There was no significant linear relationship between age and test parameters except for the test using sinusoidal-decreasing stimulation. These normative values form the base for a closer incorporation of rotational tests in occupational medicine procedures.

    This report outlines the energy research and innovation policy in the Nordic and Baltic countries - Denmark, Finland, Iceland, Norway, Sweden, Estonia, Latvia and Lithuania. The report is the result of the research project Competitive policies in the Nordic Energy Research and Innovation Area (eNERGIA). The project was co-funded by Nordic Energy Research and NIFU STEP. The objective of the project was to determine possible policy interventions targeted at the development and commercial promotion of promising renewable energy production technologies in the Nordic countries. The report is based on an analysis of the framework conditions for the sector innovation systems for energy production, with a focus on research and innovation policy in the Nordic and Baltic countries. We identified the key actors and institutions in all the eight countries studied. In addition, we conducted a performance assessment based on the quantitative indicators of publishing and patenting, international collaboration and funding data. Using these indicators as a basis, we conducted an analysis of the strengths, weaknesses, opportunities and threats (SWOT analysis) of the Nordic sector innovation systems for energy production. This analysis identified common or diverging characteristics, challenges, framework conditions, energy-technology specialisation and, most important of all, cases of good practice in key technologies. The project included two workshops, and the results of these are also reported here. The outcomes of the workshops have been used in several parts of the project: A Nordic workshop on the environmental consequences of deployment at scale of these technologies to replace existing energy systems, with a focus on wind energy and photovoltaic energy, carbon dioxide capture and storage, and second-generation bioenergy. A Nordic workshop on policy implications for Nordic Energy Research. The report comprises three parts: Part 1: Country reports Part 2: Technology reports

    Science.gov (United States)

    Romeijn, Jan-Willem

    2008-09-01

    The author discusses the abductive theory of method (ATOM) by Brian Haig from a philosophical perspective, connecting his theory with a number of issues and trends in contemporary philosophy of science. It is argued that as it stands, the methodology presented by Haig is too permissive. Both the use of analogical reasoning and the application of exploratory factor analysis leave us with too many candidate theories to choose from, and explanatory coherence cannot be expected to save the day. The author ends with some suggestions to remedy the permissiveness and lack of normative force in ATOM, deriving from the experimental practice within which psychological data are produced.

    Development of normative documents connected with nanotechnologies application in oil extraction requires necessity of accounting the peculiarity of adoption of these technologies. For example, conditions of object application, physical-chemical parameters of used nanosubstances and nanocomposites as well as some anomalies of rheological properties of nanosolutions can be referred to such ones. One of such anomalies is ambiguity of distribution laws of various rheological parameters at selected data at different experiment conditions, which on distribution diagrams are expressed by characteristic concavity in the area of lowest concentrations (up to 0,001%) of nanopowders.

    2011-12-01

    Research indicates that apoliprotein E (ApoE) plays a role in the development of Alzheimer's disease (AD) and possibly in the cognitive decline associated with normative aging. More recently, researchers have shown that ApoE is expressed in olfactory brain structures, and a relationship among ApoE, AD, and olfactory function has been proposed. In the current analyses, we investigated the contribution of ApoE and odor identification in decline trajectories associated with normative cognitive aging in various domains, using longitudinal data on cognitive performance available from the Swedish Adoption/Twin Study of Aging. Data on both ApoE status and olfactory functioning were available from 455 individuals ranging in age from 50 to 88 years at the first measurement occasion. Odor identification was measured via a mailed survey. Cognitive performance was assessed in up to 5 waves of in-person testing covering a period of 16 years. Latent growth curve analyses incorporating odor identification and ApoE status indicated a main effect of odor identification on the performance level in three cognitive domains: verbal, memory, and speed. A main effect of ApoE on rates of decline after age 65 was found for verbal, spatial, and speed factors. The consistency of results across cognitive domains provides support for theories that posit central nervous system-wide origins of the olfaction-cognition-ApoE relationship; however, olfactory errors and APOE ε4 show unique and differential effects on cognitive trajectory features.

    2015-07-01

    Full Text Available This paper presents an approach to conduct risk assessments of complex incentive systems, using a case study of the normative Peer Review Process (PRP. This research centers on appliances and adaptations of the Conflicting Incentives Risk Analysis (CIRA. First as an approach to Root Cause Analysis of a known incident, and then for a full assessment of the incentives in the PRP together with possible risk treatments. CIRA uses an alternative notion of risk, where risk modeling is in terms of conflicting incentives between the risk owner and the stakeholders concerning the execution of actions. Compared to traditional risk assessment approaches, CIRA provides an insight into the underlying incentives behind a risk, and not just the technical vulnerability, likelihood and consequence. The main contributions of this work are an approach to obtain insight into incentives as root causes, and an approach to detecting and analyzing risks from incentives in the normative PRP. This paper also discusses risk treatments in terms of incentives to make the PRP more robust, together with a discussion of how to approach risk analysis of incentives.

    It is said that when a program of saving and efficient use of the electrical energy is implemented it must be business for three: user, society and electrical utility. Regarding to the user his decision making is very simple: it is to me more cheap or more expensive, the benefit for the society can be seen from very diverse aspects, being the most important conservation of the natural resources and the environment, as far as the electric utility factors of more weight are the differing of investments and the reliability of the system. The present paper shows the importance of monitoring of the ways of energy use in different types of users, to be able to make decisions of programs: ALD, DMS (Demand Side Management) in very diverse scenarios: cities, types of users, income levels et cetera.

    The United Nations Scientific, Education, and Cultural Organization Universal Declaration on Bioethics and Human Rights (UDBHR) expresses in its title and substance a controversial linkage of two normative systems: international human rights law and bioethics. The UDBHR has the status of what is known as a "nonbinding" declaration under public international law. The UDBHR's foundation within bioethics (and association, e.g., with virtue-based or principlist bioethical theories) is more problematic. Nonetheless, the UDBHR contains socially important principles of technology transfer and transnational benefit (articles 14, 15, and 21). This paper is one of the first to explore how the disciplines of bioethics and international human rights law may interact in the UDBHR to advance the policy relevance and health impact of such principles. It investigates their normative ancestry in the UDBHR, as well as relevant conceptual differences between bioethics and public international law in this respect, and how these may be relevant to their conceptual evolution and application.

    Attitudes-norms research (the theories of planned behavior and reasoned action) has been successful in accounting for many types of behavior change. One of the strengths of this approach has been to combine individual beliefs and normative influences in the explanation of behavior change. However, the conceptualization of normative influence in these theories makes very strong assumptions about self-awareness in the selection of normative referents. These assumptions are particularly problematic when applied to female cocaine smokers, who report frequent sex while under duress or while cognitively impaired. In this study the original conceptualization of normative influence and two alternatives (assuming emotion-based and interaction-based selection of normative referents) are operationalized to evaluate stage of change for condom use among women who are heavy crack cocaine users with multiple sex partners. Results show that stage of change for use of condoms with nonmain partners is best accounted for by interaction-based selection of normative referents.

    In this paper the estimated energy saving potential in illumination, the energy end use and the technology used in commercial buildings of different use is analyzed. Estimation that departs from information of the Fideicomiso para el Ahorro de Energia (FIDE) demonstrative cases, presents the energy saving and the demand reduction in a sample of 29 buildings, among which are shopping malls, hospitals, schools, hotels, restaurants and public buildings in which energy saving programs have been carried out, with measures such as the cleaning of the luminaries and its replacement for more efficient ones. The average saving obtained is of 21.81%, in the following areas: illumination, air conditioning and others. In addition, in a sample of 4 buildings, it was observed that before applying the energy saving programs, two of them did not fulfill with the norm NOM-007-1995 (electric power density in interior lighting systems W/m{sup 2}) and later did fulfill the values and criteria of the norm. [Spanish] En el presente trabajo se analiza el potencial estimado de ahorro de energia en iluminacion, el uso final de la energia y la tecnologia empleada en edificios comerciales de uso distinto. Estimacion que parte de la informacion de los casos demostrativos del Fideicomiso para el Ahorro de Energia (FIDE), se presenta el ahorro y reduccion de la demanda en una muestra de 29 edificios, entre los que se tienen centros comerciales, hospitales, escuelas, hoteles, restaurantes y edificios publicos en los cuales se ha llevado a cabo programas de ahorro de energia, con medidas como la limpieza de las luminarias y su remplazo por otros mas eficientes. El ahorro promedio obtenido es de 21.81%, en las siguientes areas: iluminacion, aire acondicionado y otros. Ademas, en una muestra de 4 edificios, se observo que antes de aplicar los programas de ahorro de energia, dos no cumplian con la norma NOM-007-ENER-1995 (densidad de potencia electrica en alumbrado interior W/m{sup 2}) y

    Over half-a-million adolescents take part in each cycle of the Program for International Student Assessment (PISA). Yet often, researchers and policy makers across the globe tend to focus their attention primarily on the academic trajectories of adolescents hailing from highly successful education systems. Hence, a vast majority of the adolescent population who regionally and globally constitute the 'long tail of underachievement' often remain unnoticed and underrepresented in the growing literature on adolescents' academic trajectories. The present study, therefore, explored the relations of dispositions toward mathematics, subjective norms in mathematics, and perceived control of success in mathematics to mathematics work ethic as well as mathematics performance; and the mediational role of mathematics work ethic in the association between dispositional, normative, and control beliefs and mathematics performance among adolescents in one of the lowest performing education systems, Qatar. Structural equation modeling (SEM) analyses revealed that Qatari adolescents' dispositional, normative, and control beliefs about mathematics were significantly associated with their mathematics work ethic and mathematics performance, and mathematics work ethic significantly mediated the relationship between dispositional, normative, and control beliefs about mathematics and mathematics performance. However, multi-group SEM analyses indicated that these relationships were not invariant across the gender and the SES groups.
