    Full Text Available En el presente artículo entendemos por correcciones interactivas una forma de corrección de ejercicios de sistematización de gramática y de vocabulario que permite a los aprendientes interactuar entre ellos a fin de corregir dichos ejercicios sin la intervención directa del profesor. Es decir que, en lugar de que estos ejercicios se corrijan como suele hacerse tradicionalmente (por ejemplo, por medio de intercambios frontales dirigidos por el docente, podría hacerse más bien de manera interactiva, en tríos o en grupos de cuatro o cinco estudiantes, mientras el profesor circula por el aula verificando que cada uno de los integrantes participe y que la información intercambiada sea correcta. Este tipo de trabajo implica, pues, la adopción de nuevos papeles por parte de profesores y estudiantes ya que estos últimos se convierten en el centro y el epicentro del aprendizaje. No obstante, es menester tener en cuenta que estas correcciones no deben sustituir sistemáticamente al profesor puesto que este es fundamental en la corrección de ejercicios sobre contenidos complejos que, sin su acompañamiento directo, podrían conllevar consecuencias negativas para los aprendientes.

  5. Evaluating interactive digital television applications through usability heuristics Evaluando aplicaciones de televisión digital interactiva a través de heurísticas de usabilidad

    Full Text Available Interactive Digital Television (iDT is considered as the convergence of television and computer technologies. Usability evaluation for applications based on emerging information technology brings new challenges. The main iDT feature is that the user may interact with the application; therefore usability should be a main concern when designing iDT applications. Current research usually focuses on iDT applications from a technical point of view, rather than a user-centered approach. There is a need for new usability evaluation methods or at least for the use of traditional evaluations in novel ways. A set of specific usability heuristics was defined and validated, in order to help the usability evaluations of iDT applications. A usability checklist to be used when applying iDT heuristics is also proposed.La Televisión Digital Interactiva (TDi es considerada como la convergencia de la televisión y las tecnologías de la computación. La evaluación de usabilidad para aplicaciones basadas en tecnologías emergentes trae nuevos retos. La principal característica de la TDi es que los usuarios pueden interactuar con las aplicaciones; de esta manera la usabilidad es el principal aspecto a considerar cuando se diseñan aplicaciones de TDi. Las investigaciones actuales normalmente están enfocadas sobre las aplicaciones de TDi desde un punto de vista técnico, y no desde un enfoque centrado en el usuario. Hay una necesidad de nuevos métodos de evaluación de usabilidad o, por lo menos, utilizar de nuevas formas los métodos de evaluación existentes. Un conjunto de heurísticas de usabilidad específicas ha sido definido y validado, con el objetivo de ayudar en la evaluación de usabilidad de aplicaciones de TDi. También se ha propuesto una lista de verificación para ser usada al momento de aplicar las heurísticas de usabilidad.

    1999-07-01

    The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

    Full Text Available El número 8 de la Revista profundiza en las formas de expresión narrativas de no ficción audiovisual, interactiva y transmedia. A lo largo de la historia de la comunicación, el ámbito de la no ficción siempre ha sido considerado como menor respecto de su homónimo de ficción. Esto sucede también en el campo de la investigación, donde las narrativas de ficción audiovisual, interactiva y transmedia siempre han ido un paso por delante de las de no ficción. Este monográfico propone un acercamiento teórico-práctico a narrativas de no ficción como el documental, el reportaje, el ensayo, los formatos educativos o las películas institucionales, con el propósito de ofrecer una radiografía de su ubicación actual en el ecosistema de medios.  Audiovisual, interactive and transmedia non-fiction Abstract Number 8 of  Obra Digital Revista de Comunicación  explores  audiovisual, interactive and transmedia non-fiction narrative expression forms. Throughout the history of communication the field of non-fiction has always been regarded as less than its fictional namesake. This is also true in the field of research, where the studies into audiovisual, interactive and transmedia fiction narratives have always been one step ahead of the studies into nonfiction narratives. This monograph proposes a theoretical and practical approach to narrative nonfiction forms as documentary, reporting, essay, educational formats and institutional films in order to supply a picture of its current position in the media ecosystem. Keywords: Non-fiction, Audiovisual Narrative, Interactive Narrative, Transmedia Narrative.

    Full Text Available Recibido 28 de julio de 2009 • Aceptado 02 de diciembre de 2009 • Corregido 20 de marzo de 2010     Las relaciones interpersonales en el ámbito humano cobran vital sentido desde el nacimiento y se van conformando en los procesos de interacción y socialización. El contexto educativo no está exento de procesos comunicativos e interactivos. Es en el aula de clase, donde, de manera más específica, se pueden identificar dichos procesos. El aula puede ser entendida como el espacio físico-humano, en el cual se desarrollan dinámicas a partir de las interacciones entre el profesorado y el grupo estudiantil, los contenidos, las estrategias de aprendizaje y el clima de aula que de ello se genera; aspectos todos, que como parte de los procesos de enseñanza y de aprendizaje están presentes en el ámbito de la clase. Es interesante analizar el clima de aula y las dinámicas interactivas que en ella se desarrollan, independientemente de la edad del estudiante –ya sea que se trate de infantes, adolescentes o adultos–. En este caso particular, se analiza el clima de aula en el ámbito universitario, entendiendo que las dinámicas interactivas que en el aula se desarrollen, determinan un ambiente propicio o no, para el proceso de enseñanza y de aprendizaje, que ha de ser considerado, si se opta por una educación integral y de calidad.

    2015-01-01

    Full Text Available Se planteó como objetivo fundamental develar que representó, para una muestra de estudiantes de educación en la universidad pedagógica Libertador, Maracay- Venezuela, la experiencia derivada de protagonizar una estrategia didáctica interactiva y participativa, implementada en la segunda etapa de la escuela básica. Se realizó una investigación de campo con paradigma interpretativo y diseño cualitativo, naturalístico y hermenéutico. Para analizar la información y generar teoría fundamentada se empleó el método de comparación continua, con asistencia del programa de procesamiento de información cualitativa Atlas/ti, versión 5.0. Procesos de muestreo teórico, saturación y triangulación signaron la credibilidad de los hallazgos. Se encontró que, para el futuro docente, sumergirse en la didáctica participativa e interactiva significa un encuentro de vida multidimensional con la riqueza de elementos que conforman la realidad. Se percibe una autopoiesis propia de los sistemas complejos autoorganizantes, al borde del caos y la construc - ción de saberes con significados individuales y colectivos. Adicionalmente, la estrategia representa una expe - riencia neurodidáctica, al propiciarse la activación del sistema conformado por las neuronas espejo, lo cual favorece conformar empatías iniciales con los escolares. Se concluye que la experiencia señalada permite a los futuros docentes aprehender el entramado en el cual están inmersos, al ser capaces de percibir al escolar y reconocer la realidad; lo anterior potencia las posibilidades de complejizar su visión y reforzar rasgos deseables en su personalidad y en su perfil académico. Se recomienda considerar la implementación de este tipo de estrategia didáctica para favorecer la complejización de la acción educativa.

    The state of e-commerce in the Canadian upstream oil and natural gas sector is examined in an effort to discover the extent to which the .com economy has penetrated the marketplace. The overall assessment is that although the situation varies from producer to producer and process to process, a bustling digital marketplace in the Canadian oil business has yet to emerge. Nevertheless, there are several examples of companies using e-business tools to minimize technology staffing and to eliminate wasteful practices. Initiatives cited include streamlining of supply chains to cut handling costs, using application service providers to trim information technology budgets, and adopting electronic joint interest billing to save on printing, postage and re-entering data. Most notable efforts have been made by companies such as BXL Energy Limited and Genesis Exploration Limited, both of which are boosting efficiency on the inside by contracting out data storage and software applications. For example, BXL has replaced its microfilm log library occupying six cabinets, and totalling about 9,000 lbs., by a fibre optic line. All applications can now be run from a laptop which weighs three to four pounds. In a similar vein, Genesis Exploration started using application service providers (ASPs) to avoid the cost and hassle of buying and maintaining major software applications in-house. By accessing the ASPs, Genesis staff can run software without buying or installing it on their own computers. In yet another example of cutting information technology costs, Pengrowth Corporation has its network administration done remotely over the Internet by Northwest Digital Systems (NWD). As far as the industry at large is concerned, the answer appears to be in a digital marketplace specifically tailored to the upstream sector's unique profile.

Além disso, os psicanalistas têm feito uso de narrativas transferenciais a fim de comunicar suas experiências clínicas à comunidade científica, contribuindo para a produção de conhecimento nessa área. A afinidade orgânica que une o narrar ao viver autoriza-nos a conceber a narrativa como modalidade de elaboração afetivo-emocional do vivido.

    Full Text Available The majority of household savings are in the form of bank deposits. It is therefore of interest for credit institutions to tailor their deposit policy for getting finances from non-banking entities and to provide the private sector with the loans that are necessary for investment activities and consumption. This paper deals with the determinants of the saving rate of the private sector of Slovakia. Economic, financial and demographic variables influence savings. Growth of income per capita, private disposable income, elderly dependency ratio, real interest rate and inflation have a positive impact on savings, while increases in public savings indicate a crowding out effect. The inflation rate implies precautionary savings, and dependency ratio savings for bequest. There are also implications for governing institutions deciding on the implementation of appropriate fiscal and monetary operations.

    This technical brief explains the concepts of energy savings lifetimes and savings persistence and discusses how program administrators use these factors to calculate savings for efficiency measures, programs and portfolios. Savings lifetime is the length of time that one or more energy efficiency measures or activities save energy, and savings persistence is the change in savings throughout the functional life of a given efficiency measure or activity. Savings lifetimes are essential for assessing the lifecycle benefits and cost effectiveness of efficiency activities and for forecasting loads in resource planning. The brief also provides estimates of savings lifetimes derived from a national collection of costs and savings for electric efficiency programs and portfolios.

  10. Measuring industrial energy savings

    Accurate measurement of energy savings from industrial energy efficiency projects can reduce uncertainty about the efficacy of the projects, guide the selection of future projects, improve future estimates of expected savings, promote financing of energy efficiency projects through shared-savings agreements, and improve utilization of capital resources. Many efforts to measure industrial energy savings, or simply track progress toward efficiency goals, have had difficulty incorporating changing weather and production, which are frequently major drivers of plant energy use. This paper presents a general method for measuring plant-wide industrial energy savings that takes into account changing weather and production between the pre and post-retrofit periods. In addition, the method can disaggregate savings into components, which provides additional resolution for understanding the effectiveness of individual projects when several projects are implemented together. The method uses multivariable piece-wise regression models to characterize baseline energy use, and disaggregates savings by taking the total derivative of the energy use equation. Although the method incorporates search techniques, multi-variable least-squares regression and calculus, it is easily implemented using data analysis software, and can use readily available temperature, production and utility billing data. This is important, since more complicated methods may be too complex for widespread use. The method is demonstrated using case studies of actual energy assessments. The case studies demonstrate the importance of adjusting for weather and production between the pre- and post-retrofit periods, how plant-wide savings can be disaggregated to evaluate the effectiveness of individual retrofits, how the method can identify the time-dependence of savings, and limitations of engineering models when used to estimate future savings

    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

There are 308 of them and they have all been given 12 hours of training with the CERN Fire Brigade. Who are they? Quite simply, those who could one day save your life at work, the CERN first-aiders. First-aiders are recruited on a volunteer basis. "Training is in groups of 10 to 12 people and a lot of emphasis is placed on the practical to ensure that they remember the life-saving techniques we show them", explains Patrick Berlinghi, a CERN first-aid instructor from TIS Division. He is looking forward to the arrival of four new instructors, which will bring the total number to twelve (eleven firemen and one member of the Medical Service). "The new instructors were trained at CERN from 16 to 24 May by Marie-Christine Boucher Da Ros (a member of the Commission Pédagogie de l'Observatoire National Français du Secourisme, the education commission of France's national first-aid body).

    2016-01-01

    The original rationale for adopting daylight saving time (DST) was energy savings. Modern research studies, however, question the magnitude and even direction of the effect of DST on energy consumption. Representing the first meta-analysis in this literature, we collect 162 estimates from 44 studies and find that the mean reported estimate indicates modest energy savings: 0.34% during the days when DST applies. The literature is not affected by publication bias, but the results vary systemati...

  10. Can lean save lives?

    Science.gov (United States)

    Fillingham, David

    2007-01-01

    The purpose of this paper is to show how over the last 18 months Bolton Hospitals NHS Trust have been exploring whether or not lean methodologies, often known as the Toyota Production System, can indeed be applied to healthcare. This paper is a viewpoint. One's early experience is that lean really can save lives. The Toyota Production System is an amazingly successful way of manufacturing cars. It cannot be simply translated unthinkingly into a hospital but lessons can be learned from it and the method can be adapted and developed so that it becomes owned by healthcare staff and focused towards the goal of improved patient care. Working in healthcare is a stressful and difficult thing. Everyone needs a touch of inspiration and encouragement. Applying lean to healthcare in Bolton seems to be achieving just that for those who work there.

    Science.gov (United States)

    Choi, James J; Laibson, David; Madrian, Brigitte C; Metrick, Andrew

    2009-12-01

    We show that individual investors over-extrapolate from their personal experience when making savings decisions. Investors who experience particularly rewarding outcomes from saving in their 401(k)-a high average and/or low variance return-increase their 401(k) savings rate more than investors who have less rewarding experiences with saving. This finding is not driven by aggregate time-series shocks, income effects, rational learning about investing skill, investor fixed effects, or time-varying investor-level heterogeneity that is correlated with portfolio allocations to stock, bond, and cash asset classes. We discuss implications for the equity premium puzzle and interventions aimed at improving household financial outcomes.

    Full Text Available En los últimos años, las células troncales mesenquimales (Mesenchymal Stem Cells, MSC han adquirido mucha importancia debido a su gran plasticidad y su capacidad de liberar factores paracrinos con capacidad de interactuar con diversos tipos celulares, tejidos y órganos. El uso de MSC en medicina regenerativa es importante debido a que, al no expresar las moléculas del complejo mayor de histocompatibilidad (MHC clase II ni moléculas co-estimuladoras y tener baja expresión del MHC clase I, haría que no sean rechazadas por individuos de la misma especie, es posible utilizarlas no sólo de manera autóloga, sino también, eventualmente, alogénica. Sin embargo, es importante demostrar científicamente muchas de sus propiedades, entre ellas las inmunomoduladoras. Al tener varias fuentes de obtención, se debe estandarizar la que sea la mejor para garantizar la pureza y calidad de las MSC. Finalmente, es importante que cuando se trabaje con estas células se demuestre completamente las características del cultivo celular, la inmunotipificación y su capacidad de diferenciación. Se están ensayando muchas aplicaciones clínicas de las MSC. Dentro de ellas, su capacidad para mejorar la recuperación y potencial curación de úlceras crónicas como las diabéticas, ha atraído la atención por su potencial impacto terapéutico.

  2. Save energy, without entropy

    International Nuclear Information System (INIS)

    Steinmeyer, D.

    1992-01-01

    When we talk about saving energy what we usually mean is not wasting work. What we try to do when we design a process, is to use work as effectively as possible. It's hard to do that if we can't see it clearly. This paper illustrates how work can be seen (or calculated) without imposing entropy as a screen in front of it. We've all heard that the second law tells us that the entropy of the universe is increasing, and we are left with the feeling that the universe is ultimately headed for chaos, but receive little other information from this statement. A slightly more useful statement of the second law is the work potential of the universe is decreasing. However, this statement carries a needlessly negative ring. A simplified definition of the second law is: It takes work to change things. With these two corollaries: We can calculate the theoretical minimum work needed for a given change; and We can express the value of all changes in terms of work

    Full Text Available Money is lubricant and an instrument for economic transaction. Money social dimension has increased over time, transforming it from a sole economic instrument to a device for various transactions. Money economic value in society is indicated through different forms, one of which is saving, in the sense of money accumulation and its use under specific future circumstances. Women, who form half of the society, take specific approaches to money and savings. The current research aims to investigate the perspectives and changing attitude strategy to money and saving among married women. The participants of this study include 20 to 70 year-old employed household married women who were observed phenomenologically and interviewed qualitatively on saving through.   The findings of this study demonstrated women perspectives on various types of saving, ways of saving, transfer methods, saving consumption forms and their mechanism. It also revealed that while money is an economic instrument and possess the economic material; attitudes and acts related to money are influenced by social conditions that has consequently turned saving into a social phenomenon.

El objetivo es analizar nuestras aplicaciones y resultados además de describir un algoritmo que permita indicar los distintos diseños en función de la localización y el tamaño del defecto a reparar. Empleamos el colgajo frontonasal en 78 pacientes (49 mujeres y 29 varones con un rango de edad de 47 a 92 años (media de 73 años. Creamos un total de 81 defectos, puesto que en 3 casos se resecaron simultáneamente 2 tumoraciones, todos de etiología tumoral (64 carcinomas basocelulares, 16 carcinomas espinocelulares y 1 caso de léntigo maligno melanoma, localizados en el área nasal, con un tamaño mínimo de 12 x 17 mm y máximo de 30 x 35 mm (media de 22 x 25 mm. El periodo de seguimiento fue de entre 2 meses y 4 años (media de 2,5 años. Respecto a las complicaciones observadas, todas ellas menores, hubo 6 casos de necrosis marginal, 8 de dehiscencia parcial de la herida y 1 de cicatrización hipertrófica, tratándose en su mayor parte de varones fumadores. Todos los colgajos sobrevivieron con resultado estético satisfactorio. El colgajo frontonasal permite la cobertura en un sólo tiempo quirúrgico de defectos nasales independientemente de su localización, de hasta 30 x 35 mm en nuestra serie. Se trata de un colgajo seguro y versátil en sus múltiples modificaciones, con unos resultados estéticos satisfactorios. Estas ventajas son de especial importancia en pacientes de edad avanzada como alternativa a técnicas más complejas. Se trata por lo tanto, a nuestro juicio, de una opción a tener en cuenta para la reconstrucción en un único tiempo quirúrgico de defectos nasales.

Adicionalmente, se realizan cultivos de acacia y rábano en fase vivero en suelos acondicionados con diferentes hidrogeles, en el primer cultivo se evalúa el retraso en la marchitez de la especie y en el segundo la diferencia en crecimiento; simultáneamente para los cultivos, se hace el seguimiento del contenido de humedad in situ del suelo con respecto al tiempo. Se logra un método para la medición del módulo elástico y las propiedades de liberación y se establece un modelo para predecir el comportamiento de los hidrogeles en el suelo con el conocimiento de sus propiedades básicas en el estado libre. Finalmente, los resultados muestran la bondad del uso de hidrogeles en estas aplicaciones: hay mayor facilidad de liberación y retención de agua aprovechable por el suelo, retraso notable del marchitamiento en condiciones hostiles, y es mayor el crecimiento de las especies, entre otros beneficios, además se establecen pautas para definir las características del hidrogel más adecuado dependiendo de la aplicación deseada y se realiza una proyección hacia la disminución del consumo de agua para el mantenimiento de un cultivo.

  11. REMINDER: Saved Leave Scheme (SLS)

    CERN Multimedia

    2003-01-01

    Transfer of leave to saved leave accounts Under the provisions of the voluntary saved leave scheme (SLS), a maximum total of 10 days'* annual and compensatory leave (excluding saved leave accumulated in accordance with the provisions of Administrative Circular No 22B) can be transferred to the saved leave account at the end of the leave year (30 September). We remind you that unused leave of all those taking part in the saved leave scheme at the closure of the leave year accounts is transferred automatically to the saved leave account on that date. Therefore, staff members have no administrative steps to take. In addition, the transfer, which eliminates the risk of omitting to request leave transfers and rules out calculation errors in transfer requests, will be clearly shown in the list of leave transactions that can be consulted in EDH from October 2003 onwards. Furthermore, this automatic leave transfer optimizes staff members' chances of benefiting from a saved leave bonus provided that they ar...

    2005-07-01

    In this study, the architects, sponsoring utility and energy simulation specialist joined together to investigate the persistence of energy savings in three completed projects: a college library; a municipal transportation facility; and a hospital. The primary question being 'How well did the design decisions made with the help of simulation analysis translate into building operations over several years?' Design simulation and metered performance data are compared for specific energy-saving strategies. The paper provides a brief overview of the basis of selection of the three projects, the energy design assistance methods employed and the decisions made, along with their savings expectations. For each case, design characteristics, modelling assumptions, selected strategies and actual metered performance are outlined. We find evidence of appropriate levels of energy conservation, but they are not the absolute values predicted. In each case, the discrepancies between modelling assumptions and final construction or operating procedures are identified, examined and rectified. The paper illustrates that while owners are saving energy, they are not always getting the full savings potential for what they install. The paper concludes with a re-examination of the overall process. It evaluates the potential for additional savings of individual technologies and related larger utility incentives to design teams and building owners.

    Full Text Available La generación de residuos de caucho se ha convertido en una preocupación global por su impacto negativo en el medio ambiente y en la salud humana. La legislación ambiental sobre la disposición de este tipo de residuos ha venido aumentando las exigencias a los fabricantes, comercializadores y usuarios, con lo cual se ha acelerado la búsqueda de alternativas para el reaprovechamiento de los residuos de caucho. Este artículo presenta una revisión bibliográfica acerca de las principales tendencias en la utilización del caucho reciclado, incluyendo aplicaciones actualmente comercializadas y otras derivadas tanto de estudios terminados como de líneas de investigación en desarrollo. Las aplicaciones con mayor potencial de volumen consumido son del sector infraestructura y construcciones civiles, especialmente asfaltos, concretos y materiales aislantes para construcción liviana. Algunas aplicaciones con potencial en el futuro cercano son los filtros para la limpieza de aguas contaminadas y como componente en materiales compuestos con matriz termoplástica o en poliuretano. Se evidencia la pertinencia de continuar investigando sobre esta temática, que posee unos retos científicos de alta relevancia, los cuales ameritan la mayor atención por el problema ambiental significativo asociado al manejo de los residuos de caucho.

  6. Are Women Empowered to Save?

    Full Text Available Female economic empowerment – rising earnings, increased opportunities, greater labour force participation – has given many women the means to save. The shifting of responsibility for retirement security from employers and governments onto individuals has given women a reason to save. But are women actually saving? In this paper, we explore the relationship between the gender dynamics within a family and the accumulation of wealth. We find that little evidence in support of the conventional wisdom that families with a female financial manager save more and repay their debts more often. We find some evidence that male financial management leads to greater savings, and other evidence suggesting that savings patterns have a complex relationship with intra-family gender dynamics. El empoderamiento económico de la mujer – el aumento de los ingresos, mayores oportunidades, mayor participación laboral – ha dado a muchas mujeres los medios para ahorrar. Al pasar la responsabilidad de los ingresos de la jubilación de los empleadores y el gobierno a los individuos ha dado a las mujeres un motivo para ahorrar. ¿Pero realmente ahorran las mujeres? En este artículo se analizan las relaciones entre las dinámicas de género en una familia, y la acumulación de riqueza. Se ha llegado a la conclusión de que hay poca evidencia que apoye la creencia convencional de que las familias en las que una mujer gestiona las financias ahorran más y devuelven sus créditos más frecuentemente. Se ha encontrado alguna evidencia de que la gestión financiera por varones acarrea mayores ahorros, y otras evidencias que sugieren que los patrones de ahorro tienen una relación compleja con las dinámicas de género dentro de la familia.

    The Summer Time is strongly bound to the rational use of the natural resources, since it is a measure that contributes to the care of the country energy resources and the improvement of the environment. This measure consists of advancing the clock one hour in the months that have greater insolation in the country and when doing it, the electrical energy demand is reduced, a saving in the consumption of the same is obtained, resulting in a reduction of the fossil fuel consumption that is needed to generate electric energy and also the emission of polluting agents to the environment is detained. It is to emphasize that the sustainable development and the environment depend on the energy efficient use. With the application of the Summertime Schedule, the entire country participate in the care of the energy resources that are derived from their application and generates in the population a culture of the care of the energy and the environment. This program is applied to world-wide level, including the industrialized countries. In this paper the methodology implemented by the Instituto de Investigaciones Electricas (IIE) is presented, to realize the calculations of saving in electrical power consumption and the quantification of the avoided demand, as well as the main results obtained in 10 years of application of the measure in Mexico. [Spanish] El horario de verano esta fuertemente ligado al uso racional de los recursos naturales, ya que es una medida que contribuye al cuidado de los recursos energeticos del pais y la mejora del medio ambiente.

  14. Revolving fund for energy saving

    International Nuclear Information System (INIS)

    Prebensen, K.

    1993-01-01

    A key issue in Eastern Europe is the adjustment of prices from the former COMECON level to a level conforming with free market conditions. In the case of household heating, this issue involves the removal of government subsidies leading to sharply increasing prices, metering of individual consumption, improving the efficiency of energy production, distribution and use - where savings of 30-50% in each link are technically feasible - thereby providing a potential for a adapting consumption patterns to higher energy prices, provided that funds are available. Currently, investment in commercial heat production and distribution systems have received substantial international support - whereas investment in reduction of demand has been little exploited. The Revolving Fund for Energy Savings in Polish Households is a concept for efficient financing of small-scale projects. It aims at financing, on the level of housing cooperatives, on the basis of a simplified lending and project evaluation procedure, well suited to current Polish conditions or an organizationally and financially weak banking system and little developed technical knowledge in the field of energy saving. A general introduction to the issue is given and technical problems are elaborated. The implementation of Energy Savings in Housing seen from the banking point of view, and a current pilot scheme for financing, are described. (AB)

    1998-01-01

    With the end of the cold war, funding for the Environmental Management program increased rapidly as nuclear weapons production facilities were shut down, cleanup responsibilities increased, and facilities were transferred to the cleanup program. As funding for the Environmental Management (EM) program began to level off in response to Administration and Congressional efforts to balance the Federal budget, the program redoubled its efforts to increase efficiency and get more productivity out of every dollar. Cost savings and enhanced performance are an integral pair of Hanford Site operations. FY1997 was the third year of a cost savings program that was initially defined in FY 1995. The definitions and process remained virtually the same as those used in FY 1996

    A demonstration of low-cost insulation and weatherization techniques was a part of phase 1 of the Krakow Clean Fossil Fuels and Energy Efficient Project. The objectives were to identify a cost-effective set of measures to reduce energy used for space heating, determine how much energy could be saved, and foster widespread implementation of those measures. The demonstration project focused on 4 11-story buildings in a Krakow housing cooperative. Energy savings of over 20% were obtained. Most important, the procedures and materials implemented in the demonstration project have been adapted to Polish conditions and applied to other housing cooperatives, schools, and hospitals. Additional projects are being planned, in Krakow and other cities, under the direction of FEWE-Krakow, the Polish Energie Cities Network, and Biuro Rozwoju Krakowa.

  2. Risk transfer via energy-savings insurance

    International Nuclear Information System (INIS)

    Mills, Evan

    2003-01-01

    Among the key barriers to investment in energy efficiency are uncertainties about attaining projected energy savings and potential disputes over stipulated savings. The fields of energy management and risk management are thus intertwined. While many technical methods have emerged to manage performance risks (e.g. building diagnostics and commissioning), financial methods are less developed in the energy management arena than in other segments of the economy. Energy-savings insurance (ESI) - formal insurance of predicted energy savings - transfers and spreads both types of risk over a larger pool of energy efficiency projects and reduces barriers to market entry of smaller energy service firms who lack sufficiently strong balance sheets to self-insure the savings. ESI encourages those implementing energy-saving projects to go beyond standard measures and thereby achieve more significant levels of energy savings. Insurance providers are proponents of improved savings measurement and verification techniques, as well as maintenance, thereby contributing to national energy-saving objectives. If properly applied, ESI can potentially reduce the net cost of energy-saving projects by reducing the interest rates charged by lenders, and by increasing the level of savings through quality control. Governmental agencies have been pioneers in the use of ESI and could continue to play a role

    1998-03-01

    Federal legislation allows federal agencies to retain up to 50% of the savings associated with implementing energy efficiency and water conservation measures and practices. Given budget pressures to reduce expenditures, the use of retained savings to fund additional projects represents a source of funds outside of the traditional budget cycle. The Southwest Region Federal Aviation Administration (FAA) has tasked Pacific Northwest National Laboratory (PNNL) to develop a model retained savings program for Southwest Region FAA use and as a prototype for consideration by the FAA. PNNL recommends the following steps be taken in developing a Southwest Region FAA retained savings program: Establish a retained savings mechanism. Determine the level at which the retained savings should be consolidated into a fund. The preliminary recommendation is to establish a revolving efficiency loan fund at the regional level. Such a mechanism allows some consolidation of savings to fund larger projects, while maintaining a sense of facility ownership in that the funds will remain within the region

    In the transition towards a 100% renewable energy system, energy savings are essential. The possibility of energy savings through conservation or efficiency increases can be identified in, for instance, the heating and electricity sectors, in industry, and in transport. Several studies point...... to various optimal levels of savings in the different sectors of the energy system. However, these studies do not investigate the idea of energy savings being system dependent. This paper argues that such system dependency is critical to understand, as it does not make sense to analyse an energy saving...... without taking into account the actual benefit of the saving in relation to the energy system. The study therefore identifies a need to understand how saving methods may interact with each other and the system in which they are conducted. By using energy system analysis to do hourly simulation...

  5. Saving in cycles: how to get people to save more money.

    2014-02-01

    Low personal savings rates are an important social issue in the United States. We propose and test one particular method to get people to save more money that is based on the cyclical time orientation. In contrast to conventional, popular methods that encourage individuals to ignore past mistakes, focus on the future, and set goals to save money, our proposed method frames the savings task in cyclical terms, emphasizing the present. Across the studies, individuals who used our proposed cyclical savings method, compared with individuals who used a linear savings method, provided an average of 74% higher savings estimates and saved an average of 78% more money. We also found that the cyclical savings method was more efficacious because it increased implementation planning and lowered future optimism regarding saving money.

    Full Text Available The test bench system described in this paper performs experiments on piezoelectric materials used in road traffic applications, covering a range between 14 and 170 km/h, which is considered enough for testing under standard traffic conditions. A software has been developed to control the three phase induction motor driver and to acquire all the measurement data of the piezoelectric materials. The mass over each system’s axis can be selected, with a limit of 60 kg over each wheel. The test bench is used to simulate the real behaviour of buried piezoelectric cables in road traffic applications for both light and heavy vehicles. This new test bed system is a powerful research tool and can be applied to determine the optimal installation and configuration of the piezoelectric cable sensors and opens a new field of research: the study of energy harvesting techniques based on piezoelectric materials.

    En este trabajo se define y propone un banco de ensayos que permite testar materiales piezoeléctricos para aplicaciones viales en sus diferentes configuraciones en un rango de velocidad entre los 14 y los 170 km/h, lo que cubre sobradamente las condiciones de tráfico real. Tanto el control del variador de velocidad del motor trifásico que realiza el accionamiento del banco, como la recogida de resultados de medida en las pruebas de excitación y de fatiga de los compuestos piezoeléctricos, se realiza de forma automatizada mediante código informatico. El peso que soporta cada eje del banco es configurable, permitiendo reproducir las señales obtenidas en aplicaciones donde los materiales piezoeléctricos actúan de sensores enterrados en la calzada para vehículos tanto pesados como ligeros. Gracias a esta nueva herramienta se facilita la investigación con materiales de este tipo en aplicaciones viales optimizando tanto el tipo como la disposición e instalación de los mismos, además de abrir el camino a la novedosa investigación sobre

    Jacobsen, F.R.

    1993-01-01

    The Czechoslovak/Danish project on energy savings in buildings proves that it is possible to save up to 30% of the energy in buildings. 10% can be saved at an investment of 27 bill KCS. The total investment that is needed to save 30% is 140 bill KCS. Further energy savings can be obtained through more energy efficient supply systems. Information dissemination is important for the energy saving programme as are economic incentives. Investments in energy savings should be profitable for the investor, but this is not the case in the Czech and Slovak republics today. Changes are needed. Energy prices are still to low, compared to investment costs. Financial possibilities are not satisfactory for private investors. Price systems are not favourable to investment in energy savings. Training is needed for boiler men and energy consultants. Legislation is essential for the support of the full range of activities in the energy sector. Research and Development activities must back up the development of the sector. Pilot projects can illuminate the savings potential. The production of technical equipment for control and metering and production of insulation materials must be promoted. (AB)

    2005-07-01

    During 2004, oil prices reached levels unprecedented in recent years. Though world oil markets remain adequately supplied, high oil prices do reflect increasingly uncertain conditions. Many IEA member countries and non-member countries alike are looking for ways to improve their capability to handle market volatility and possible supply disruptions in the future. This book aims to provide assistance. It provides a new, quantitative assessment of the potential oil savings and costs of rapid oil demand restraint measures for transport. Some measures may make sense under any circumstances; others are primarily useful in emergency situations. All can be implemented on short notice ? if governments are prepared. The book examines potential approaches for rapid uptake of telecommuting, ?ecodriving?, and car-pooling, among other measures. It also provides methodologies and data that policymakers can use to decide which measures would be best adapted to their national circumstances. This ?tool box? may help countries to complement other measures for coping with supply disruptions, such as use of strategic oil stocks.

    Among the key barriers to investment in energy efficiency improvements are uncertainties about attaining projected energy savings and apprehension about potential disputes over these savings. The fields of energy management and risk management are thus intertwined. While many technical methods have emerged to manage performance risks (e.g. building commissioning), financial risk transfer techniques are less developed in the energy management arena than in other more mature segments of the economy. Energy Savings Insurance (ESI) - formal insurance of predicted energy savings - is one method of transferring financial risks away from the facility owner or energy services contractor. ESI offers a number of significant advantages over other forms of financial risk transfer, e.g. savings guarantees or performance bonds. ESI providers manage risk via pre-construction design review as well as post-construction commissioning and measurement and verification of savings. We found that the two mos t common criticisms of ESI - excessive pricing and onerous exclusions - are not born out in practice. In fact, if properly applied, ESI can potentially reduce the net cost of energy savings projects by reducing the interest rates charged by lenders, and by increasing the level of savings through quality control. Debt service can also be ensured by matching loan payments to projected energy savings while designing the insurance mechanism so that payments are made by the insurer in the event of a savings shortfall. We estimate the U.S. ESI market potential of $875 million/year in premium income. From an energy-policy perspective, ESI offers a number of potential benefits: ESI transfers performance risk from the balance sheet of the entity implementing the energy savings project, thereby freeing up capital otherwise needed to ''self-insure'' the savings. ESI reduces barriers to market entry of smaller energy services firms who do not have sufficiently strong balance

    As demonstrated by the March 2011 earthquake and tsunami-triggered blackouts in Japan, electricity shortfalls can happen anytime and anywhere. Countries can minimise the negative economic, social and environmental impacts of such electricity shortfalls by developing emergency energy-saving strategies before a crisis occurs. This new IEA report highlights preliminary findings and conclusions from electricity shortfalls in Japan, the United States, New Zealand, South Africa and Chile. It draws on recent analysis to: reinforce well-established guidelines on diagnosing electricity shortfalls, identifying energy-saving opportunities and selecting a package of energy-saving measures; and highlight proven practice for implementing emergency energy-saving programmes. This paper will be valuable to government, academic, private-sector and civil-society stakeholders who inform, develop and implement electricity policy in general, and emergency energy-saving programmes in particular.

Recently, global climate change has been recognized as a serious near term problem. Power saving techniques for electronic devices are important. In PON system, the ONU (Optical Network Unit) power saving scheme has been studied and defined in XG-PON. In this paper, we propose an ONU power saving scheme for EPON. Then, we present an analysis of the power reduction effect and the data transmission delay caused by the ONU power saving scheme. According to the analysis, we propose an efficient provisioning method for the ONU power saving scheme which is applicable to both of XG-PON and EPON.

  4. Can this merger be saved?

    Cliffe, S

    1999-01-01

    In this fictional case study, a merger that looked like a marriage made in heaven to those at corporate headquarters is feeling like an infernal union to those on the ground. The merger is between Synergon Capital, a U.S. financial-services behemoth, and Beauchamp, Becker & Company, a venerable British financial-services company with strong profits and an extraordinarily loyal client base of wealthy individuals. Beauchamp also boasts a strong group of senior managers led by Julian Mansfield, a highly cultured and beloved patriarch who personifies all that's good about the company. Synergon isn't accustomed to acquiring such companies. It usually encircles a poorly managed turnaround candidate and then, once the deal is done, drops a neutron bomb on it, leaving file cabinets and contracts but no people. Before acquiring Beauchamp, Synergon's macho men offered loud assurances that they would leave the tradition-bound company alone-provided, of course, that Beauchamp met the ambitious target numbers and showed sufficient enthusiasm for cross-selling Synergon's products to its wealthy clients. In charge of making the acquisition work is Nick Cunningham, one of Synergon's more thoughtful executives. Nick, who was against the deal from the start, is the face and voice of Synergon for Julian Mansfield. And Mansfield, in his restrained way, is angry at the constant flow of bureaucratic forms, at the rude demands for instant information, at the peremptory changes. He's even dropping broad hints at retirement. Nick has already been warned: if Mansfield goes, you go. Six commentators advise Nick on how to save his job by bringing peace and prosperity to the feuding couple.

    Four studies tested the idea that saving money can buffer death anxiety and constitute a more effective buffer than spending money. Saving can relieve future-related anxiety and provide people with a sense of control over their fate, thereby rendering death thoughts less threatening. Study 1 found that participants primed with both saving and spending reported lower death fear than controls. Saving primes, however, were associated with significantly lower death fear than spending primes. Study 2 demonstrated that mortality primes increase the attractiveness of more frugal behaviors in save-or-spend dilemmas. Studies 3 and 4 found, in two different cultures (Polish and American), that the activation of death thoughts prompts people to allocate money to saving as opposed to spending.

    Directory of Open Access Journals (Sweden)

    Tomasz Zaleskiewicz

    Full Text Available Four studies tested the idea that saving money can buffer death anxiety and constitute a more effective buffer than spending money. Saving can relieve future-related anxiety and provide people with a sense of control over their fate, thereby rendering death thoughts less threatening. Study 1 found that participants primed with both saving and spending reported lower death fear than controls. Saving primes, however, were associated with significantly lower death fear than spending primes. Study 2 demonstrated that mortality primes increase the attractiveness of more frugal behaviors in save-or-spend dilemmas. Studies 3 and 4 found, in two different cultures (Polish and American, that the activation of death thoughts prompts people to allocate money to saving as opposed to spending. Overall, these studies provided evidence that saving protects from existential anxiety, and probably more so than spending.

  11. Electric energy savings from new technologies

    Energy Technology Data Exchange (ETDEWEB)

    Moe, R.J.; Harrer, B.J.; Kellogg, M.A.; Lyke, A.J.; Imhoff, K.L.; Fisher, Z.J.

    1986-01-01

    Purpose of the report is to provide information about the electricity-saving potential of new technologies to OCEP that it can use in developing alternative long-term projections of US electricity consumption. Low-, base-, and high-case scenarios of the electricity savings for ten technologies were prepared. The total projected annual savings for the year 2000 for all ten technologies were 137 billion kilowatt hours (BkWh), 279 BkWh, and 470 BkWh, respectively, for the three cases. The magnitude of these savings projections can be gauged by comparing them to the Department's reference case projection for the 1985 National Energy Policy Plan. In the Department's reference case, total consumption in 2000 is projected to be 3319 BkWh. Thus, the savings projected here represent between 4% and 14% of total consumption projected for 2000. Because approximately 75% of the base-case estimate of savings are already incorporated into the reference forecast, reducing projected electricity consumption from what it otherwise would have been, the savings estimated here should not be directly subtracted from the reference forecast.

    Fultz, Keith O.; Milans, Flora H.; Kirk, Roy J.; Welker, Robert A.; Sparling, William J.; Butler, Sharon E.; Irwin, Susan W.

    1989-04-01

    A number of impediments have discouraged federal agencies from using shared energy savings contracts. As of November 30, 1988, only two federal agencies - the U.S. Postal Service (USPS) and the Department of the Army -had awarded such contracts even though they can yield significant energy and cost savings. The three major impediments we identified were uncertainty about the applicability of a particular procurement policy and practice, lack of management incentives, and difficulty in measuring energy and cost savings. To address the first impediment, the Department of Energy (DOE) developed a manual on shared energy savings contracting. The second impediment was addressed when the 100th Congress authorized incentives for federal agencies to enter into shared savings contracts. DOE addressed the third impediment by developing a methodology for calculating energy consumption and cost savings. However, because of differing methodological preferences, this issue will need to be addressed on a contract-by-contract basis. Some state governments and private sector firms are using performance contracts to reduce energy costs in their buildings and facilities. We were able to identify six states that were using performance contracts. Five have established programs, and all six states have projects under contract. The seven energy service companies we contacted indicated interest in federal shared energy savings contracting

  13. Survey of industrial radioisotope savings

    International Nuclear Information System (INIS)

    1965-01-01

    Only three decades after the discovery of artificial radioactivity and two after radioisotopes became available in quantity, methods employing these as sources or tracers have found widespread use, not only in scientific research, but also in industrial process and product control. The sums spent by industry on these new techniques amount to millions of dollars a year. Realizing the overall attitude of industry to scientific progress - to accept only methods that pay relatively quickly - one can assume that the economic benefits must be of a still larger order of magnitude. In order to determine the extent to which radioisotopes are in daily use and to evaluate the economic benefits derived from such use, IAEA decided to make an 'International Survey on the Use of Radioisotopes in Industry'. In 1962, the Agency invited a number of its highly industrialized Member States to participate in this Survey. Similar surveys had been performed in various countries in the 1950's. However, the approaches and also the definition of the economic benefits differed greatly from one survey to another. Hence, the Agency's approach was to try to persuade all countries to conduct surveys at the same time, concerning the same categories of industries and using the same terms of costs, savings, etc. In total, 24 Member States of the Agency agreed to participate in the survey and in due course they submitted contributions. The national reports were discussed at a 'Study Group Meeting on Radioisotope Economics', convened in Vienna in March 1964. Based upon these discussions, the national reports have been edited and summarized. A publication showing the administration of the Survey and providing all details is now published by the Agency. From the publication it is evident that in general the return of technical information was quite high, of the order of 90%, but, unfortunately the economic response was much lower. However, most of the reports had some bearing on the economic aspects

  14. Freshwater savings from marine protein consumption

    International Nuclear Information System (INIS)

    Gephart, Jessica A; Pace, Michael L; D’Odorico, Paolo

    2014-01-01

    Marine fisheries provide an essential source of protein for many people around the world. Unlike alternative terrestrial sources of protein, marine fish production requires little to no freshwater inputs. Consuming marine fish protein instead of terrestrial protein therefore represents freshwater savings (equivalent to an avoided water cost) and contributes to a low water footprint diet. These water savings are realized by the producers of alternative protein sources, rather than the consumers of marine protein. This study quantifies freshwater savings from marine fish consumption around the world by estimating the water footprint of replacing marine fish with terrestrial protein based on current consumption patterns. An estimated 7 600 km 3  yr −1 of water is used for human food production. Replacing marine protein with terrestrial protein would require an additional 350 km 3  yr −1 of water, meaning that marine protein provides current water savings of 4.6%. The importance of these freshwater savings is highly uneven around the globe, with savings ranging from as little as 0 to as much as 50%. The largest savings as a per cent of current water footprints occur in Asia, Oceania, and several coastal African nations. The greatest national water savings from marine fish protein occur in Southeast Asia and the United States. As the human population increases, future water savings from marine fish consumption will be increasingly important to food and water security and depend on sustainable harvest of capture fisheries and low water footprint growth of marine aquaculture.

    OVERVIEW\\ud \\ud There are two approaches to valuing travel time savings to business people. The first is that which has formed the basis of UK policy for about 30 years, and which is set out in Section 2. This takes the value of travel time savings on employer’s business as equal to the gross wage rate plus an allowance for other costs that the employer saves.

    2006-10-01

    There are individuals, including children, dying needlessly in poverty-stricken third world countries. Many of these deaths could be prevented if pharmaceutical companies provided the drugs needed to save their lives. Some believe that because pharmaceutical companies have the power to save lives, and because they can do so with little effort, they have a special obligation. I argue that there is no distinction, with respect to obligations and responsibilities, between pharmaceutical companies and other types of companies. As a result, to hold pharmaceutical companies especially responsible for saving lives in third world countries is unjustified.

    This article focuses on household water use in Spain by analyzing the influence of a detailed set of factors. We find that, although the presence of both water-saving equipment and water-conservation habits leads to water savings, the factors that influence each are not the same. In particular, our results show that those individuals most committed to the adoption of water-saving equipment and, at the same time, less committed to water-conservation habits tend to have higher incomes.

Aunque el secado por atomización ha sido para la industria un proceso práctico y económico, su aplicación con alginato se ha visto limitada por la viscosidad y velocidad de gelificación. Por el contrario, la técnica por extrusión ha sido la técnica tradicional empleada en las últimas décadas, debido a la uniformidad de las microcápsulas en su forma y tamaño.

Es necesario superar el uso exclusivo de la evaluación tradicional con el fin de adoptar una evaluación formativa, modalidad que busca identificar las fallas y necesidades de los estudiantes durante el proceso educativo con el fin de recibir retroalimentación para tomar las medidas necesarias que permitan mejorar la enseñanza y el aprendizaje. Siguiendo esta necesidad, y buscando ayudar a los profesores en la aplicación de una evaluación formativa, algunos recursos tecnológicos han sido desarrollados. El presente trabajo tiene como objetivo describir el potencial de tres aplicaciones (Armet, The Cell y 3DClass en el proceso de evaluación formativa usando las bases de datos asociadas a cada aplicación. Los resultados muestran que estas aplicaciones proporcionan métricas de evaluación más transparentes, coherentes y que permiten al profesor sistematizar criterios e indicadores, lo que reduce la subjetividad del proceso de evaluación formativa y el tiempo necesario para la preparación, tabulación y análisis de datos. Gracias a que con esta tecnología es posible verificar en tiempo real el número de errores totales y por pregunta preguntas con el mayor número de errores recurrentes, preguntas con el mayor y menor índice de aciertos y el tiempo que los alumnos emplean para desarrollar la actividad, es posible determinar el progreso de los alumnos a lo largo del tiempo e identificar puntualmente dónde ocurren los errores; esto permite una investigación minuciosa sobre sus posibles causas.

    Full Text Available Until now, as a way of reducing greenhouse gas emissions from Japanese homes, the emphasis has been on reduction of energy consumption for air-conditioning and lighting. In recent years, there has been progress in CO2 emission reduction through research into the water-saving performance of bathroom fixtures such as toilets and showers. Simulations have shown that CO2 emissions associated with water consumption in Japanese homes can be reduced by 25% (1% of Japan’s total CO2 emissions by 2020 through the adoption of the use of water-saving fixtures. In response to this finding, a program to promote the replacement of current fixtures with water-saving toilet bowls and thermally insulated bathtubs has been added to the Government of Japan’s energy-saving policy. Furthermore, CO2 emission reduction through widespread use of water-saving fixtures has been adopted by the domestic credit system promoted by the Government of Japan as a way of achieving CO2 emission-reduction targets; application of this credit system has also begun. As part of a bilateral offset credit mechanism promoted by the Government of Japan, research to evaluate the CO2 reduction potential of the adoption of water-saving fixtures has been done in the city of Dalian, in China.

    In some industries, most notably food and drink and chemicals, refrigeration accounts for a significant proportion of overall site energy costs. For instance, in the industrial handling of meat, poultry and fish, it often accounts for 50% of total energy costs. In ice-cream production the proportion is 70%. In a number of commercial sectors, refrigeration also represents a significant proportion of overall energy costs. For example: Cold storage 90%; Food supermarkets 50%; Small shops with refrigerated cabinets 70% or over; Pubs and clubs 30%. Against these high costs, even a small reduction in refrigeration energy use can offer significant cost savings, resulting in increased profits. Energy saving need not be expensive. Energy savings of up to 20% can be realised in many refrigeration plant through actions that require little or no investment. In addition, improving the efficiency and reducing the load on a refrigeration plant can improve reliability and reduce the likelihood of a breakdown. Most organisations can save energy and money on refrigeration by: More efficient equipment; Good maintenance; Housekeeping and control. This publication provides an understanding of the operation of refrigeration systems, identifies where savings can be realised and will enable readers to present an informed case on energy savings to key decision makers within their organisation.

  7. Saving-enhanced memory: the benefits of saving on the learning and remembering of new information.

    Storm, Benjamin C; Stone, Sean M

    2015-02-01

    With the continued integration of technology into people's lives, saving digital information has become an everyday facet of human behavior. In the present research, we examined the consequences of saving certain information on the ability to learn and remember other information. Results from three experiments showed that saving one file before studying a new file significantly improved memory for the contents of the new file. Notably, this effect was not observed when the saving process was deemed unreliable or when the contents of the to-be-saved file were not substantial enough to interfere with memory for the new file. These results suggest that saving provides a means to strategically off-load memory onto the environment in order to reduce the extent to which currently unneeded to-be-remembered information interferes with the learning and remembering of other information. © The Author(s) 2014.

  8. Exploring the time-saving bias: How drivers misestimate time saved when increasing speed

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available According to the time-saving bias, drivers underestimate the time saved when increasing from a low speed and overestimate the time saved when increasing from a relatively high speed. Previous research used a specific type of task --- drivers were asked to estimate time saved when increasing speed and to give a numeric response --- to show this. The present research conducted two studies with multiple questions to show that the time-saving bias occurs in other tasks. Study 1 found that drivers committed the time-saving bias when asked to estimate (a the time saved when increasing speed or (b the distance that can be completed at a given time when increasing speed or (c the speed required to complete a given distance in decreasing times. Study 2 showed no major differences in estimations of time saved compared to estimations of the remaining journey time and also between responses given on a numeric scale versus a visual analog scale. Study 3 tested two possible explanations for the time-saving bias: a Proportion heuristic and a Differences heuristic. Some evidence was found for use of the latter.

  18. Energy Savings from Industrial Water Reductions

    Energy Technology Data Exchange (ETDEWEB)

    Rao, Prakash; McKane, Aimee; de Fontaine, Andre

    2015-08-03

    Although it is widely recognized that reducing freshwater consumption is of critical importance, generating interest in industrial water reduction programs can be hindered for a variety of reasons. These include the low cost of water, greater focus on water use in other sectors such as the agriculture and residential sectors, high levels of unbilled and/or unregulated self-supplied water use in industry, and lack of water metering and tracking capabilities at industrial facilities. However, there are many additional components to the resource savings associated with reducing site water use beyond the water savings alone, such as reductions in energy consumption, greenhouse gas emissions, treatment chemicals, and impact on the local watershed. Understanding and quantifying these additional resource savings can expand the community of businesses, NGOs, government agencies, and researchers with a vested interest in water reduction. This paper will develop a methodology for evaluating the embedded energy consumption associated with water use at an industrial facility. The methodology developed will use available data and references to evaluate the energy consumption associated with water supply and wastewater treatment outside of a facility’s fence line for various water sources. It will also include a framework for evaluating the energy consumption associated with water use within a facility’s fence line. The methodology will develop a more complete picture of the total resource savings associated with water reduction efforts and allow industrial water reduction programs to assess the energy and CO2 savings associated with their efforts.

    Full Text Available „Neither a borrower nor a lender be” recommends Shakespeare in Hamlet. The advice seems particularly interesting in nowadays society where a person can be easily found in both approximate situations, in the same time. It goes without saying that saving and borrowing do not describe mutually exclusive strategies of financial management and thus many people retain savings or carry on saving at the same time as having debts. We add to this fact a more pragmatically wisdom, the one of the economist Robert Solow -“We (economists think of wealth as fungible; we think a dollar is a dollar. Why don't they (the others do so?” (Solow, 1987 – and we naturally ask ourselves if the mechanism of having simultaneous savings and debts is a rational one, according to traditional economics.Making appeal to the emerging body of behavioral economics literature we reach to the mental accounting theory to see if it can explain savings inclination versus debt inclination. The main research question we want to explore is the following: if mental accounting prevents people from spending money from one „mental account” on goods belonging to another one, will people – after using all their money from a given account – be willing to go into debt to buy goods belonging to this account in a situation when they still have money in other accounts?

    Hospital laundries are one of the largest consumers of water and electrical and thermal energy. This paper examined the energy savings achieved by a system using the hot wastewater from the washing process. Hospital laundries consume thermal energy using steam, which is produced in boilers by burning diesel oil or natural gas. Electrical energy for the mechanical drives, ventilation and also the lighting required in the laundry area are big consumers of energy. The paper presented the proposed system and discussed the parameters of the system and system dimensioning. The paper also provided and discussed an interpretation of steam and energy savings. The proposed system was considered to be economically viable, simple in its construction, installation and operation. From the application of the suggested system, the cost savings resulted in a satisfactory payback period for the capital invested of approximately three to five years. 14 refs., 4 tabs., 2 figs.

    Full Text Available El presente trabajo analiza el papel de los jóvenes consumidores en el contexto de los nuevos procesos comunicativos que surgen de tecnologías emergentes: el uso de las aplicaciones de marca en los dispositivos móviles. Éstos incorporan funcionalidades sociales y comunicativas cada vez más complejas y, entre ellas, las aplicaciones para teléfonos inteligentes que vinculan publicidad comercial y pagos forman un campo novedoso pero de interés prioritario para distintos actores comunicativos, como son las marcas comerciales, los servicios bancarios y las propias compañías tecnológicas. En ese contexto la presente investigación describe y codifica cualitativamente cómo los usuarios entienden, perciben y utilizan, como prosumidores, las aplicaciones de marca corporativa y los pagos. Para ello se aplican técnicas de investigación en cuatro grupos focales, de edades comprendidas entre los 18 y 24 años, compuestos por jóvenes universitarios españoles estudiantes en Comunicación, como usuarios que muestran una predisposición y una adopción temprana de estas prácticas. Las respuestas de las reuniones del grupo de discusión permitieron una clasificación de las prácticas comunicativas. En conclusión, se constata una alta predisposición de estos consumidores activos por interactuar con contenidos comerciales, estableciendo redes sociales bajo el amparo de una cultura e imagen de marca, como forma de cohesión grupal. Otros usos se relacionan con el entretenimiento y la información, al tiempo que aún se muestran reticentes al pago de productos o servicios mediante el dispositivo móvil.

    The primary objective of this study was to estimate the current life-cycle cost-effective (i.e., economic) energy savings potential in Federal buildings and the corresponding capital investment required to achieve these savings, with Federal financing. Estimates were developed for major categories of energy efficiency measures such as building envelope, heating system, cooling system, and lighting. The analysis was based on conditions (building stock and characteristics, retrofit technologies, interest rates, energy prices, etc.) existing in the late 1990s. The potential impact of changes to any of these factors in the future was not considered.

    This chapter discusses the economics, physical and chemical processes, and safety of nuclear fuel recycling. The spent fuel must be chemically reprocessed in order to recover uranium and plutonium. Topics considered include indifference costs, recycling in light water reactors (LWRs), plutonium in fast reactors, the choice between recycling and storage, safeguards, and weapons proliferation. It is shown that the economics of recycling nuclear fuel involves the actual costs and savings of the recycling operation in terms of money spent, made, and saved, and the impact of the recycling on the future cost of uranium

    Gale, William G; Harris, Benjamin H; Levine, Ruth

    2012-01-01

    This article highlights the prevalence and economic outcomes of financial illiteracy among American households, and reviews previous research that examines how improving financial literacy affects household saving. Analysis of the research literature suggests that previous financial literacy efforts have yielded mixed results. Evidence suggests that interventions provided for employees in the workplace have helped increase household saving, but estimates of the magnitude of the impact vary widely. For financial education initiatives targeted to other groups, the evidence is much more ambiguous, suggesting a need for more econometrically rigorous evaluations.

    Programs regarding to energy saving in Brasil arised by the early 80's from the concern with oil products consumption. The situation has changed and electricity is growing in importance when energy conservation is discussed. Thus, the government, following examples from abroad, has been trying to overcome the barriers that obstruct a massive process evolution towards energy saving, since the potential is spread out in many society segments. One important issue is related to financing energy conservation. This paper attempts to analyze the utilities efforts allied to public and private banks investments towards energy conservation financing. (author)

    2000-03-01

    Full Text Available This paper analyzes anew the relationship between taxation and the household saving rate. On the basis of standard savings and tax revenue data from a sample of OECD countries, it provides compelling empirical evidence of a powerful impact of taxes on household savings. In particular, income taxes are shown to affect negatively the household saving rate much more than consumption taxes.

    Full Text Available Resumen: En este trabajo se propone el uso de plataformas para el desarrollo de aplicaciones virtuales como herramientas para el modelado de robots manipuladores. La propuesta se basa en aprovechar el gran potencial que actualmente tienen estas plataformas para solucionar la dinámica de cuerpos rígidos, lo que permite modelar de forma sencilla los aspectos mecánicos del manipulador. Por otro lado, la posibilidad ofrecida por estas plataformas de incorporar código de programación en lenguajes convencionales, permite modelar el comportamiento dinámico de sistemas físicos reales, tales como sensores y actuadores, lo que hace posible la implementación de una etapa virtual de instrumentación y control tal y como se realiza en un robot real. El uso de estas plataformas permite modelar desde cero cualquier robot manipulador. El modelado de un robot paralelo reconfigurable es presentado como caso de estudio. Abstract: This paper describes the use of platforms for the development of virtual applications as tools for modeling of robot manipulators. The proposal is based on take advantage of the potential that these platforms currently have for solving the rigid body dynamics, which easily allows modeling the mechanical aspects of the manipulator. On the other hand, the possibility offered by these platforms of incorporate programming code in conventional languages allows to modeling the dynamic behavior of real physical systems, such as sensors and actuators, which allows implementing the development of the instrumentation and control stage of an industrial robot in the same way as a real one. Using these platforms allows the modeling from the bases of any manipulator robot. The modeling of a reconfigurable parallel robot is presented as a case study.

    Full Text Available Resumen: El control visual es una disciplina de gran actualidad dentro del control de robots, y dentro de ésta, los algoritmos de predicción se usan para estimar la localización de objetos o características visuales proporcionadas por un sensor con retardo (cámara. Algunos de los algoritmos más utilizados son: el filtro de Kalman; los filtros alpha-beta/gamma (αβ/γ; el AKF; el SKF; etc. El mayor problema de algunos de ellos es conseguir que su implementación permita trabajar en aplicaciones con fuertes restricciones temporales o de tiempo real. En este artículo se presenta un nuevo método de predicción, denominado FMF, basado en la fusión o combinación borrosa de varios filtros, y por tanto con un alto coste computacional. En el artículo se estudia a través de simulación la mejora obtenida con la predicción del FMF respecto a los filtros individuales, lo que justifica su interés. Así mismo, se desarrolla su implementación de tiempo real en una FPGA empleando técnicas de paralelización y segmentado. La viabilidad, robustez y fiabilidad del algoritmo propuesto se ha comprobado mediante una aplicación experimental de control visual.

  4. Boiler house modernization through shared savings program

    Energy Technology Data Exchange (ETDEWEB)

    Breault, R.W. [Tecogen, Waltham, MA (United States)

    1995-12-31

    Throughout Poland as well as the rest of Eastern Europe, communities and industries rely on small heat only boilers to provide district and process heat. Together these two sectors produce about 85,000 MW from boilers in the 2 to 35 MW size range. The bulk of these units were installed prior to 1992 and must be completely overhauled to meet the emission regulations which will be coming into effect on January 1, 1998. Since the only practical fuel is coal in most cases, these boilers must be either retrofit with emission control technology or be replaced entirely. The question that arises is how to accomplish this given the current tight control of capital in Poland and other East European countries. A solution that we have for this problem is shared savings. These boilers are typically operating with a quiet low efficiency as compared to western standards and with excessive manual labor. Installing modernization equipment to improve the efficiency and to automate the process provides savings. ECOGY provides the funds for the modernization to improve the efficiency, add automation and install emission control equipment. The savings that are generated during the operation of the modernized boiler system are split between the client company and ECOGY for a number of years and then the system is turned over in entirety to the client. Depending on the operating capacity, the shared savings agreement will usually span 6 to 10 years.

    The project ''Energy Saving Baking Methods'', run as part of the Energy Research Project-1984, and has as its aim to investigate potentials for energy saving by employing microwaves in the baking process. The project is a follow-up of the Nordic Industry Fund project which was completed in 1983. Smaller test ovens with IR long waves, warm air convection and microwaves of 2,47 GHz were used. Measurements of heat distribution from all three energy sources have been made. Extensive experiments have been carried out in order to develope baking methods for white loaves which are energy saving, but where the quality of the bread does not undergo any form of deterioration. Tests were made using microwaves alone, and in combination with hot air and IR. A resulting saving 35% baking time was achieved, and a further reduction of baking time can be reached where a greater improvement of energy distribution can take place, especially in the case of microwaves and IR.

    Sikorski, B.D.; O'Donnell, B.A.

    1999-01-01

    This paper discusses the cost savings impact of employing an energy manager with a 16,000-employee corporation. The corporation, Canada's second largest airline, is currently operating nearly 3,000,000 ft 2 of mixed-use facilities spread across the country, with an annual energy budget for ground facilities of over Cdn $4,000,000. This paper outlines the methodology used by the energy manager to deploy an energy management program over a two-year period between April 1995 and May 1997. The paper examines the successes and the lessons learned during the period and summarizes the costs and benefits of the program. The energy manager position was responsible for developing an energy history database with more than 100 active accounts and for monitoring and verifying energy savings. The energy manager implemented many relatively low-cost energy conservation measures, as well as some capital projects, during the first two years of the program. In total, these measures provided energy cost savings of $210,000 per year, or 5% of the total budget. In each case, technologies installed as part of the energy retrofit projects provided not only cost savings but also better control, reduced maintenance, and improved working conditions for employees

    This paper performs a literature review and meta-analysis of water savings from several types of advanced irrigation controllers: rain sensors (RS), weather-based irrigation controllers (WBIC), and soil moisture sensors (SMS).The purpose of this work is to derive average water savings per controller type, based to the extent possible on all available data. After a preliminary data scrubbing, we utilized a series of analytical filters to develop our best estimate of average savings. We applied filters to remove data that might bias the sample such as data self-reported by manufacturers, data resulting from studies focusing on high-water users, or data presented in a non-comparable format such as based on total household water use instead of outdoor water use. Because the resulting number of studies was too small to be statistically significant when broken down by controller type, this paper represents a survey and synthesis of available data rather than a definitive statement regarding whether the estimated water savings are representative.

    Commercial retail electricity rates commonly include a demand charge component, based on some measure of the customer’s peak demand. Customer-sited solar PV can potentially reduce demand charges, but the magnitude of these savings can be difficult to predict, given variations in demand charge designs, customer loads, and PV generation profiles. Moreover, depending on the circumstances, demand charges from solar may or may not align well with associated utility cost savings. Lawrence Berkeley National Laboratory (Berkeley Lab) and the National Renewable Energy Laboratory (NREL) are collaborating in a series of studies to understand how solar PV can reduce demand charge levels for a variety of customer types and demand charges designs. Previous work focused on residential customs with solar. This study, instead, focuses on commercial customers and seeks to understand the extent and conditions under which rooftop can solar reduce commercial demand charges. To answer these questions, we simulate demand charge savings for a broad range of commercial customer types, demand charge designs, locations, and PV system characteristics. This particular analysis does not include storage, but a subsequent analysis in this series will evaluate demand charge savings for commercial customers with solar and storage.

    In 1991, the Northwest utilities faced a complex situation. They needed new sources of electrical power to avoid future deficits. A significant block of energy savings was available in the manufactured housing sector in the form of energy savings from increased insulation to new manufactured homes. The manufacturers were interested in saving the electricity in the homes, but would only deal with the utility sector as a whole. Half of the homes targeted were sited in investor-owned utility (IOU) service territories, and half in the public sector made up of utilities that purchased some or all of their electricity from the Bonneville Power Administration. Utilities agreed to acquire energy from manufacturers In the form of thermal efficiency measures specified by the Bonneville Power Administration. The program that resulted from over one year of negotiations was called the Manufactured Housing Acquisition Program, or MAP. Manufacturers, the utilities, State Energy Offices, the Northwest Power Planning Council and Bonneville all worked closely and with tenacity to build the program that went into effect on April 1, 1992, and should save the region between 7 and 9 megawatts, enough energy to supply 11,000 homes in the Northwest

  9. Advertising energy saving programs: The potential environmental cost of emphasizing monetary savings.

    Many consumers have monetary or environmental motivations for saving energy. Indeed, saving energy produces both monetary benefits, by reducing energy bills, and environmental benefits, by reducing carbon footprints. We examined how consumers' willingness and reasons to enroll in energy-savings programs are affected by whether advertisements emphasize monetary benefits, environmental benefits, or both. From a normative perspective, having 2 noteworthy kinds of benefit should not decrease a program's attractiveness. In contrast, psychological research suggests that adding external incentives to an intrinsically motivating task may backfire. To date, however, it remains unclear whether this is the case when both extrinsic and intrinsic motivations are inherent to the task, as with energy savings, and whether removing explicit mention of extrinsic motivation will reduce its importance. We found that emphasizing a program's monetary benefits reduced participants' willingness to enroll. In addition, participants' explanations about enrollment revealed less attention to environmental concerns when programs emphasized monetary savings, even when environmental savings were also emphasized. We found equal attention to monetary motivations in all conditions, revealing an asymmetric attention to monetary and environmental motives. These results also provide practical guidance regarding the positioning of energy-saving programs: emphasize intrinsic benefits; the extrinsic ones may speak for themselves.

    proven exhaustively with models of the Electric Power System of the Comision Federal de Electricidad with: 405 nodes, 111 generators and 613 branches, giving precise results even in the most extreme conditions, the savings of computational time go from 30 to a 50% according to the type of study made. [Spanish] El objetivo principal de esta tesis es el de presentar un modelo de reduccion de redes que pueda ser utilizado en la simulacion de diversos fenomenos que ocurren en la operacion de los Sistemas Electricos de Potencia (SEP). El trabajo muestra el desarrollo y aplicacion del equivalente en estudios de: Flujos de potencia en estado estable, estabilidad transitoria, comportamiento dinamico generalizado y comportamiento de la frecuencia simplificado. Este modelo surge como resultado de la observacion y analisis del comportamiento del SEP, separando efectos de: cargas, generaciones, red electrica y sus elementos en derivacion. El algoritmo utiliza un enfoque alterno a la presentacion tradicional de equivalentes, donde las cargas se ponderan en el proceso de eliminacion a sus nodos vecinos, basados en una reduccion vectorial de las lineas o transformadores que se involucran al nodo eliminado. De igual forma se transfieren los efectos de los elementos en derivacion. Los resultados asi obtenidos tienen un desajuste pequeno en potencia reactiva por lo que es necesario compensar el caso base reducido. La compensacion solo es necesaria en los nodos que fueron vecinos a uno eliminado durante el proceso y esta compensacion se hace considerando las ramas que finalmente resultaron conectadas a dicho nodo. El algoritmo utiliza los voltajes obtenidos en el caso base original para calcular las potencias complejas de salida de cada una de las ramas que conectan al nodo que se compensa. Las sumatorias de potencias resultantes son los ajustes al caso base reducido. El modelo de equivalentes propuesto permite el analisis de contingencias en puntos donde los equivalentes tradicionales no

    The Affordable Care Act is transforming American federalism and creating strain between the states and the federal government. By expanding the scale of intergovernmental health programs, creating new state requirements, and setting the stage for increased federal fiscal oversight, the act has disturbed an uneasy truce in American federalism. This article outlines a policy proposal designed to harness cooperative federalism, based on the shared state and federal desire to control health care cost growth. The proposal, which borrows features of the Medicare Shared Savings Program, would provide states with an incentive in the form of an increased share of the savings they generate in programs that have federal financial participation, as long as they meet defined performance standards.

    This report first presents Energy Saving Certificates as one of among other instruments aimed at reducing energy consumption, and indicates how the French consumer is concerned. The benefits of this instrument are outlined: low cost, autonomy, awareness-raising, quantitative assessment of achieved energy savings. Its objectives and results since its creation in 2006 are commented, and the report outlines that this type of instrument is spreading over Europe. The authors show that its efficiency has been improved along the years due to a periodic review of standardised operation sheets, a simplification of the declaration, and an optimization of related programmes. Besides, targets have been better identified. The report outlines that assessment and controls must however be strengthened in order to reduce financial risks and potential drifts.

    Energy saving certificates (in French CEE for certificats d'economie d'energie) have been implemented in 2006, and have proven to be a rather efficient tool of public policy, with a low cost, and a good social acceptability, notably due to its hybrid nature (incentive and coercive) in function of the targeted actors. Thus, this document addresses and discusses the interest of such instruments for the public environmental policy. It outlines that instruments tend to be always less coercive, and then comments the example of these energy saving certificates: brief presentation, discussion and explanation of their efficiency, multi-dimensional nature of this instrument, benefits of more or less coercive instruments depending on the actors (State, households, energy providers)

Particularly, the optimization of the pressure levels and number of the utility networks for steam distribution inside plant facilities, is considered, in order to maximize heat recovery in the process units, and electric power production in the central steampower generation plant. A computer program of general application, based on profitability evaluation at various fuel oil prices and different project configurations, has been developed for these purposes. The general measures applicable within certain limits are then briefly examined. The task of the process engineer is discussed in the perspective of the ''energy saving'' goal.

    Full Text Available Various ceramic supports besides standard soda-lime glass have been utilized as substrates for deposition of molybdenum and copper indium diselenide layers (substrate/Mo/CuInSe2 heterostructures for application in thin film photovoltaic solar cells. Molybdenum layers have been prepared simultaneously onto the different substrates by electron gun assisted evaporation. Subsequently, CuInSe2 thin films have been obtained by direct electrodeposition onto the Mo-coated substrates. The influence of the substrate characteristics onto the optical and structural properties of the developed materials has been determined to evaluate the possibility of substituting the commonly utilized glass by ceramics that can wide the applications of these photovoltaic systems. The obtained results indicate that the scattering factor and the structural stress in the layers are minimized when the morphological characteristics of the ceramic are close to those of the standard glass substrates.

    1982-01-01

    When the quantity of paint used for industrial coating is assumed to be 420,000 tons, it is estimated that the area being coated is 2.8 billion m 2 , the petroleum required for pretreatment steam, drying and baking is 1.68 million tons, and the required amount of energy saving is 120,000 tons per year in terms of petroleum. The authors examined how the adoption of electron beam curing for surface coating contributes to the energy saving. So far, it has been said that electron beam curing is more efficient than thermal or light curing in energy consumption, but the premise condition was not clear. The theoretical energy requirement for thermal curing, light curing and electron beam curing was calculated and compared. The comparison of the measured values was also performed. The amount of energy required for thermal curing, UV light curing and electron beam curing was roughly 100:10:1, and the cost of energy for them was 50:5:1. In spite of the large merit of electron beam curing, it has not spread as expected, because of the repayment cost of the facility and the cost of inert gas required for the process. Energy saving is brought about by electron beam curing, but the overall cost must be examined case by case. (Kako, I.)

    Science.gov (United States)

    1996-01-01

    This article describes the activity among charitable committees to provide education and shelter to orphans and homeless children in India. "Save The Children Committee" of the All India Women's Conference began operations during the Bengal famine of 1943 by providing shelter to children who were homeless or did not know where their parents were. The Bengal Relief Committee also provided shelters, which later became Children's Homes, which were operated by the Save The Children Committee. Funding support for the homes came from individual donors and organizations. The Bengal government provided Rs.25/month/child for 450 children. Children's homes were set up in Phola, Mymensingh, and Brahmanberia, in the present day Bangladesh, and in Bankura. The Committee took over homes in Mahishadal, Khagda, and Belbeni. After 1948, the Children's Homes in East Pakistan were transferred to India. In 1952, several Children's Committees merged. Funds were supplied by international organizations. Government support levels varied over time. Schools for orphans changed from an emphasis on self-reliance and work to ordinary schooling. Brief descriptions are provided for homes at Pifa, Mangalgunge in Bongaon Subdivision, Thakurpukur in 24-Parganas, and Khagda in Midnapore district. For example, the home at Khagda was begun by the Bengal Relief Committee at the time of the famine of 1944. Save The Children Committee took over its operations in 1946. It is now a home for 21 boys. The boys have access to a good high school, have achieved academically, and received respect from the community.

  18. Energy saving potential in existing industrial compressors

    International Nuclear Information System (INIS)

    Vittorini, Diego; Cipollone, Roberto

    2016-01-01

    The Compressed Air Sector accounts for a mean 10% worldwide electricity consumption, which ensures about its importance, when energy saving and CO_2 emissions reduction are in question. Since the compressors alone account for 15% overall industry electricity consumption, it appears vital to pay attention to machine performances. The paper presents an overview of present compressor technology and focuses on saving directions for screw and sliding vanes machines, according to data provided by the Compressed Air and Gas Institute and PNEUROP. Data were processed to obtain consistency with fixed reference pressures and organized as a function of main operating parameters. Each sub-term, contributing to the overall efficiency (adiabatic, volumetric, mechanical, electric, organic), was considered separately: the analysis showed that the thermodynamic improvement during compression achievable by splitting the compression in two stages, with a lower compression ratio, opens the way to significantly reduce the energy specific consumption. - Highlights: • Compressors technology overview in industrial compressed air systems. • Market compressors efficiency baseline definition. • Energy breakdown and evaluation of main efficiency terms. • Assessment of air cooling-related energy saving potential. • Energy specific consumption reduction through dual stage compression.

  19. Good practice in saving energy at school

    2014-05-01

    We teach students between 14 and 18 years old at a high school in Italy. In the first class, one of the topics we treat is related to the atmosphere. The students learn the composition of air, the importance of the natural greenhouse effect in keeping the average temperature of the planet and how human activity is increasing the level of greenhouse gases, enhancing greenhouse effect and causing global warming. It is possible to reach this knowledge using different materials and methods such as schoolbooks, articles, websites or films, individual or group work, but as students gradually become aware of the problem of climate change due to global warming, it is necessary to propose a solution that can be experienced and measured by students. This is the aim of the project "Switch off the light, to switch on the future". The project doesn't need special materials to be carried out but all the people in the community who work and "live" at school should participate in it. The project deals directly with saving electric energy, by changing the habits of the use of electricity. Saving electric energy means saving CO2 emitted to atmosphere, and consequently contributing to the reduction of greenhouse gases emission. Normally, lights in the school are switched on in the early morning and switched off at the end of lessons. Nobody is responsible to turn out the lights in classes, so students choose one or two "Light guardians" who are responsible for the light management. Simple rules for light management are written and distributed in the classes so that the action of saving energy is spread all over the school. One class participates in the daily data collection from the electricity meter, before and after the beginning of the action. At the end of the year the data are treated and presented to the community, verifying if the electric consumption has been cut down or not. This presentation is public, with students who directly introduce collected data, results and

    2018-03-01

    At present, energy saving and consumption reduction require energy saving and consumption reduction measures for thermal power plant, establishing an evaluation system for energy conservation and consumption reduction is instructive for the whole energy saving work of thermal power plant. By analysing the existing evaluation system of energy conservation and consumption reduction, this paper points out that in addition to the technical indicators of power plant, market activities should also be introduced in the evaluation of energy saving and consumption reduction in power plant. Ttherefore, a new evaluation index of energy saving and consumption reduction is set up and the example power plant is calculated in this paper. Rresults show that after introducing the new evaluation index of energy saving and consumption reduction, the energy saving effect of the power plant can be judged more comprehensively, so as to better guide the work of energy saving and consumption reduction in power plant.

    Several countries are considering extending Daylight Saving Time (DST) in order to conserve energy, and the U.S. will extend DST by one month beginning in 2007. However, projections that these extensions will reduce electricity consumption rely on extrapolations and simulations rather than empirical evidence. This paper, in contrast, examines a quasiexperiment in which parts of Australia extended DST in 2000 to facilitate the Sydney Olympics. Using detailed panel data and a triple differences specification, we show that the extension did not conserve electricity, and that a prominent simulation model overstates electricity savings when it is applied to Australia.

    A set of models are employed to estimate the potential of total energy saved of productions and segmented energy saving for telecom operators in China. During the estimation, the total energy saving is divided into that by technology and management, which are derived from technical reform and progress, and management control measures and even marketing respectively, and the estimating methodologies for energy saving potential of each segment are elaborated. Empirical results from China Mobile indicate that, first, the technical advance in communications technology accounts for the largest proportion (70%–80%) of the total energy saved of productions in telecom sector of China. Second, technical reform brings about 20%–30% of the total energy saving. Third, the proportions of energy saving brought by marketing and control measures appear relatively smaller, just less than 3%. Therefore, China's telecom operators should seize the opportunity of the revolution of communications network techniques in recent years to create an advanced network with lower energy consumption

    Full Text Available The article examines the main problems and solutions of energy saving and energy supply in Ukraine. Low energy efficiency has become one of the main factors of the crisis in the Ukrainian economy. The most relevant scientific and methodical approaches to assessment of the level of energy consumption and saving are indicated. The comparative analysis of annual energy use has been made. A potential to solve energy supply problems is strongly correlated with the ability to ensure the innovative development of economy for efficient and economical use of existing and imported energy resources. The ways for reducing of energy resource consumption have been suggested. Creation of technological conditions for the use of alternative energy sources is considered to be rational also. The development of renewable sources of energy (alternative and renewable energy sources will provide a significant effect in reducing the use of traditional energy sources, harmful emissions and greenhouse gas. Under these conditions, increasing of energy efficiency of economy and its competitiveness can be real. Improvement of environmental and social conditions of citizens of the country will mark a positive step towards the EU, and also will cancel some problems of the future generation.

    The growing investment by governments and electric utilities in energy efficiency programs highlights the need for simple tools to help assess and explain the size of the potential resource. One technique that is commonly used in this effort is to characterize electricity savings in terms of avoided power plants, because it is easier for people to visualize a power plant than it is to understand an abstraction such as billions of kilowatt-hours. Unfortunately, there is no standardization around the characteristics of such power plants. In this letter we define parameters for a standard avoided power plant that have physical meaning and intuitive plausibility, for use in back-of-the-envelope calculations. For the prototypical plant this article settles on a 500 MW existing coal plant operating at a 70% capacity factor with 7% T and D losses. Displacing such a plant for one year would save 3 billion kWh/year at the meter and reduce emissions by 3 million metric tons of CO 2 per year.

    1991-01-01

    The expansion of electricity-producing plants has, in Denmark until now, taken place in accordance with the demand for electricity. Recently, it has been suggested that the cost of the further development of such systems is greater than the cost of instigating and carrying out energy conservation efforts. The aim of the project was to evaluate the consequences for power producing plants of a reduction of the electricity consumption of end-users. A method for the analysis of the costs involved in the system and operation of power plants contra the costs that are involved in saving electricity is presented. In developing a model of this kind, consideration is given to the interplay of the individual saving project and the existing or future electricity supply. Thus it can be evaluated to what extent it would be advisable to substitute investments in the development of the capacity of the power plants with investments in the reduction of electricity consumption by the end users. This model is described in considerable detail. It will be tested in representative situations and locations throughout the Nordic countries. (AB) 17 refs

    Smart solutions to reduce the energy consumption are continuously part of investigation in the refrigeration technology. This article subscribed the technology on which way energy can be saved at the operation of screw compressors which are used in air conditioners and refrigerating machinery. The combination of frequency control and Vi-control (intrinsic volumetric ratio) such as researched in the laboratory of RefComp is for the user attractive because the energy efficiency during part load operation is much better. Smart uses of thermodynamics, electric technology and electronic control are the basics of these applications. According to the manufacturer's information it is possible with these new generation screw compressors to save approx. 26% energy in comparison with the standard screw compressor. [Dutch] In dit artikel wordt de technologie omschreven waarmee veel energie bespaard kan worden bij schroefcompressoren die worden gebruikt in airconditioningsystemen en koel- en vriesinstallaties. De combinatie van frequentieregeling en Vi- regeling (Vi is de intrinsieke volumetrische verhouding) zoals onderzocht in het laboratorium van RefComp biedt de gebruiker veel voordelen doordat de energie-efficintie van de compressor tijdens deellast enorm wordt verbeterd. Slim gebruik van thermodynamika, elektrotechniek en elektronica vormen de basis van deze toepassing. Volgens de fabrikant kan met deze nieuwe generatie schroefcompressoren circa 26 procent op het energiegebruik tijdens deellast worden bespaard in vergelijking met de standaard serie schroefcompressoren.

  18. Chinese hotel general managers' perspectives on energy-saving practices

    Science.gov (United States)

    Zhu, Yidan

    As hotels' concern about sustainability and budget-control is growing steadily, energy-saving issues have become one of the important management concerns hospitality industry face. By executing proper energy-saving practices, previous scholars believed that hotel operation costs can decrease dramatically. Moreover, they believed that conducting energy-saving practices may eventually help the hotel to gain other benefits such as an improved reputation and stronger competitive advantage. The energy-saving issue also has become a critical management problem for the hotel industry in China. Previous research has not investigated energy-saving in China's hotel segment. To achieve a better understanding of the importance of energy-saving, this document attempts to present some insights into China's energy-saving practices in the tourist accommodations sector. Results of the study show the Chinese general managers' attitudes toward energy-saving issues and the differences among the diverse hotel managers who responded to the study. Study results indicate that in China, most of the hotels' energy bills decrease due to the implementation of energy-saving equipments. General managers of hotels in operation for a shorter period of time are typically responsible for making decisions about energy-saving issues; older hotels are used to choosing corporate level concerning to this issue. Larger Chinese hotels generally have official energy-saving usage training sessions for employees, but smaller Chinese hotels sometimes overlook the importance of employee training. The study also found that for the Chinese hospitality industry, energy-saving practices related to electricity are the most efficient and common way to save energy, but older hotels also should pay attention to other ways of saving energy such as water conservation or heating/cooling system.

    2011-09-01

    Due to the innate complexity of the task drivers have to manage multiple goals while driving and the importance of certain goals may vary over time leading to priority being given to different goals depending on the circumstances. This study aimed to investigate drivers' behavioral regulation while managing multiple goals during driving. To do so participants drove on urban and rural roads in a driving simulator while trying to manage fuel saving and time saving goals, besides the safety goals that are always present during driving. A between-subjects design was used with one group of drivers managing two goals (safety and fuel saving) and another group managing three goals (safety, fuel saving, and time saving) while driving. Participants were provided continuous feedback on the fuel saving goal via a meter on the dashboard. The results indicate that even when a fuel saving or time saving goal is salient, safety goals are still given highest priority when interactions with other road users take place and when interacting with a traffic light. Additionally, performance on the fuel saving goal diminished for the group that had to manage fuel saving and time saving together. The theoretical implications for a goal hierarchy in driving tasks and practical implications for eco-driving are discussed. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available La hipnosis es un tema controversial y estigmatizado. Las múltiples investigaciones de las últimas décadas han permitido tanto derrumbar mitos, como evidenciar sus mecanismos y aplicaciones, y cómo estos contribuyen al bienestar de las personas. El objetivo de este trabajo es describir las aplicaciones actuales de la hipnosis clínica en el contexto latinoamericano. Con este fin se realizó una revisión sistemática de la literatura en las bases de datos Lilacs y SciELo, empleando los términos “hipnosis”, “hipnosis clínica” y “Latinoamé- rica”. Se incluyeron revisiones de la literatura, artículos originales que tuvieran poblaciones latinoamericanas y presentaciones de caso, publicados entre 1990 y el 2016, escritos en español. La búsqueda inicial arrojó 202 artículos; después de eliminar replicaciones y los que no cumplían criterios de inclusión, 20 artículos fueron incluidos en la revisión. Las aplicaciones de la hipnosis descritas incluyen manejo del dolor, preparación a la cirugía, tabaquismo, problemas gastrointestinales y otras condiciones médicas, aplicaciones en niños y adolescentes, etcétera. Desafortunadamente, los estudios revisados tienen importantes falencias metodológicas, lo que dificulta extraer conclusiones sólidas. A pesar de que la hipnosis es eficaz, práctica, costo-efectiva y aplicada en una gran variedad de problemas clínicos, la evidencia que avala su uso en el contexto latinoamericano es muy limitada. Se requieren investigaciones con una metodología más rigurosa que permitan evidenciar su eficacia en este contexto.

    KOMAC has been operating a 100 MeV proton linear Accelerator. There are about 10,000 PVs for operating the 100 MeV proton linac. It is important to archive the operating parameters for operating beam lines and machine study. The parameters are reported manually and with screenshot. There not fixed reporting type so it is difficult to compare archived data. To improve and compensate the reporting system, a Save and Restoration application, which is based on JAVA has been implemented and connected with KOMAC Control system based on EPICS with JCA library. The operating data are saved in Save and Restoration Server in file type, and are restored to the required values using the saved files. This paper presents Implementation of the Save and Restoration application and its function. The group list is shown in restore page using reload button. The saved value of the PVs in group is shown as selecting a group which clients require and current values are appeared beside the restore value table to compare with saved data. The set restore button input the values in restore value table to each PV. The Save and Restore application save and restore the value of the PVs that clients require. The application is installed in client PC but data are archived in save and restore server in file format.

    1981-01-01

    One way of saving energy in metal coating is by using electrically heated infrared dryers with medium-wave radiation (2 to 3 ..mu..m). The absorbing capacity of varnishes and plastic coatings is >90% in this range so that the radiation energy is almost completely transformed into heat. Medium-wave radiation sources have a much higher service life than short-wave sources (30.000 hours of operation) and do not require cooling; compared with long-wave sources, they have a higher heat transfer and thus much shorter drying times. The main fields of application, a cost example, and practical examples among the customers of Messrs. Eisenmann are presented.

    2006-01-01

    Since the ecological footprint analysis in 1970s suggested changing consumption patterns and overpopulation concerns, energy policy such as energy conservation and use of renewable energy has become of prime importance. Several results of the long-term energy demand and supply analysis in 2050 or 2100 to reduce drastically carbon dioxide emission as a measure against global warming, showed the necessity of nuclear power deployment as well as maximum efforts to save energy, exploitation of the separation and disposal of carbon dioxide, and shifting energy sources to fuels that emit less greenhouse gases or non-fossil fuels. As a promising means to contribute to long-term energy supply, nuclear power generation is expected with improving safety, economic efficiency, environmental adaptability, and nuclear proliferation resistance of the technologies.

    Full Text Available The paper presents the analysis of the dynamics of the heat transfer through the outer wall of the thermal technical spaces, taking into account the impact of the sinusoidal nature of the changes in atmospheric temperature. These temporal variations of the input on the outer surface of the chamber divider result at the output of the sinusoidal change on the inner wall of the room, but suitably suppressed and shifted in phase. Properly selected phase shift is clearly important for saving energy used for the operation associated with the maintenance of a specific regime of heat inside the thermal technical chamber support. Laboratory tests of the model and the actual object allowed for optimal design of the chamber due to the structure of the partition as well as due to the orientation of the geographical location of the chamber.

  12. Reform Proposals for Replenishing Retirement Savings

    Full Text Available The 2008-2009 economic crisis dealt a serious blow to Canadians’ retirement savings. While markets have since partially recovered, the ratio of Canadians’ household net-worth relative to disposable income still remains below where it was in 2007. So much wealth that workers had accumulated to prepare for retirement has been wiped away, while the years since 2008 that might have otherwise been spent compounding retirement savings have been spent, instead, on trying to recover losses in a low-interest-rate environment that has limited returns. With large waves of older workers approaching retirement age, and these future retirees projected to live longer than previous cohorts, Canada now faces the very realistic scenario that a significant number of people will reach retirement age without the funds they will need to provide a comfortable post-working-life income. Canadian policy-makers may not have the ability to restore that destroyed wealth. And with most governments already struggling to resolve serious deficits, the situation is not likely to be ameliorated with anything that requires additional spending, or that could reduce tax revenues. But there are policy reforms available that can help at least in better preparing the coming waves of retirees for a financially secure retirement. The reforms need not be far-reaching to have a meaningful impact. And they need not be costly, either. They can include a modest expansion of the Canada Pension Plan (CPP to allow larger contributions — shared by employers and employees, or covered entirely by employees — that would, in turn, allow retiring workers to draw a larger maximum pension, rather than having to rely on the guaranteed income supplement (GIS. CPP contributions could also be made deductible from taxable income, like RRSP investments, to encourage workers to maximize contributions. To minimize an increase in payroll taxes, the eligibility age for CPP benefits could be increased to

    The objective of this study was to develop, monitor, analyze, and report on an integrated resource-conservation program highlighting efficient residential appliances and fixtures. The sites of study were 50 homes in two water-constrained communities located in Oregon. The program was designed to maximize water savings to these communities and to serve as a model for other communities seeking an integrated approach to energy and water resource efficiency. The program included the installation and in-place evaluation of energy- and water-efficient devices including the following: horizontal axis clothes washers (and the matching clothes dryers), resource-efficient dishwashers, an innovative dual flush low-flow toilet, low-flow showerheads, and faucet aerators. The significance of this activity lies in its integrated approach and unique metering evaluation of individual end-use, aggregated residential total use, and system-wide energy and water benefits.

    This study assesses the costs and benefits of nuclear power plant life extension (NUPLEX) for the overall US under widely varying economic assumptions and compares these with alternative new coal- fired plants (NEWCOAL). It is found that NUPLEX saves future electricity consumers more than 3 cents/-kwh compared with NEWCOAL. The NUPLEX costs and benefits for existing individual US nuclear power plants under base-line, or most likely, assumptions are assessed to determine the effects of the basic plant design and plant age. While benefits vary widely, virtually all units would have a positive benefit from NUPLEX.

    Full Text Available La población mundial está envejeciendo progresivamente. Se prevé que en 2050 el número de personas mayores de 60 años alcance los dos mil millones en el mundo. El empleo de las Tecnologías de la Información y Comunicación (TIC puede suponer para la población de mayor edad un impacto significativo en su calidad de vida, contribuyendo a conseguir mayores activos, disminuyendo la marginalización y el aislamiento social. Aunque existen diferencias importantes en el uso que los Mayores hacen de Internet y sus aplicaciones respecto al resto de la población, hay que considerar que este segmento no constituye un grupo homogéneo. Este trabajo busca comprobar si dentro del grupo de los Mayores existen diferencias en la frecuencia de uso de distintas aplicaciones basadas en Internet, en función de la edad, el sexo, el nivel de estudios alcanzados y la actividad laboral desarrollada en el pasado. Los resultados demuestran que existen diferencias significativas en el empleo de algunas aplicaciones en función de las variables sociodemográficas analizadas.

    Full Text Available Abstract Background The cost-benefit of raccoon rabies control strategies such as oral rabies vaccination (ORV are under evaluation. As an initial quantification of the potential cost savings for a control program, the collection of selected rabies cost data was pilot tested for five counties in New York State (NYS in a three-year period. Methods Rabies costs reported to NYS from the study counties were computerized and linked to a human rabies exposure database. Consolidated costs by county and year were averaged and compared. Results Reported rabies-associated costs for all rabies variants totalled $2.1 million, for human rabies postexposure prophylaxes (PEP (90.9%, animal specimen preparation/shipment to laboratory (4.7%, and pet vaccination clinics (4.4%. The proportion that may be attributed to raccoon rabies control was 37% ($784,529. Average costs associated with the raccoon variant varied across counties from $440 to $1,885 per PEP, $14 to $44 per specimen, and $0.33 to $15 per pet vaccinated. Conclusion Rabies costs vary widely by county in New York State, and were associated with human population size and methods used by counties to estimate costs. Rabies cost variability must be considered in developing estimates of possible ORV-related cost savings. Costs of PEPs and specimen preparation/shipments, as well as the costs of pet vaccination provided by this study may be valuable for development of more realistic scenarios in economic modelling of ORV costs versus benefits.

    PRIBIC pant (Pollutants Reduction In small Blomass Combustion systems) at CEDER is a facility specifically designed to do biomass combustion tests. In these tests is necessary to known the values of different sensors in real time. With this information the PRIBIC plant is regulated to its optimum point of work and it's possible to follow the operation criteria and get test objectives. Different electronic instruments record information about the plant operation. A software application was developed to let a centralized monitorization of that information. the application communicates with the instrumentation, recovers data, lets operators see data in real time and saves the information in files. An important part of this document describes that application, and some considerations to generalize this kind of developments to other Experimental Plants, including cost estimations. Descriptions of plants, analysis of the problem, result evaluations, and conclusions can also be found in the document. (Author) 13 refs.

    modelizacion, y aplicacion en convertidores PWM, esta aun por estudiar y valorar. El primer Capitulo consiste en una breve introduccion al problema de la regulacion cruzada y la impedancia cruzada para posteriormente describir las tecnicas de post-regulacion actualmente mas empleadas, con especial atencion al post-regulador con transformador controlado. El Capitulo segundo trata del estudio de las caracteristicas estaticas del postregulador con transformador controlado. Partiendo de los estudios disponibles sobre el postregulador se plantean mejoras en su modo de actuacion y se discuten tres alternativas diferentes para controlar el transformador. Las dos primeras consisten en emplear un convertidor auxiliar Boost en sus dos modos de funcionamiento, continuo y discontinuo. La tercera consiste en controlar el transformador con una tension PWM directamente, sin filtrado. Finalmente se comprueba experimentalmente, para el estado estacionario, el funcionamiento del post-regulador para cada uno de los tres metodos de control. El Capitulo tercero trata de la dinamica de la salida controlada con el post-regulador cuando este emplea un convertidor auxiliar tipo Boost. Mediante la tecnica de promediado de variables de estado se propone el modelo de pequena senal, tanto para el modo continuo como para el modo discontinuo de funcionamiento del convertidor auxiliar. Los resultados mas significativos de esta seccion son las expresiones analiticas de las impedancias cruzadas y de la impedancia de la salida post-regulada. Como complemento al modelo de pequena senal se plantea un modelo de gran senal implementado sobre el simulador Pspice. Con este nuevo modelo se reproducen los resultados obtenidos con el modelo de pequena senal y ademas es posible simular los transitorios en las tensiones de salida ante cambios de carga. La modelizacion del convertidor cuando el transformador se controla con una tension PWM sin filtrar es el objetivo del Capitulo 4. En las secciones siguientes del Capitulo

    2011-01-01

    We analyse life-cycle saving decisions when households use simple heuristics, or rules of thumb, rather than solve the underlying intertemporal optimization problem. We simulate life-cycle saving decisions using three simple rules and compute utility losses relative to the solution of the optimization problem. Our simulations suggest that utility losses induced by following simple decision rules are relatively low. Moreover, the two main saving motives re ected by the canonical life-cyc...

    What is the socially optimal level of liquidity in a retirement savings system? Liquid retirement savings are desirable because liquidity enables agents to flexibly respond to pre-retirement events that raise the marginal utility of consumption. On the other hand, pre-retirement liquidity is undesirable when it leads to under-saving arising from, for example, planning mistakes or self-control problems. This paper compares the liquidity that six developed economies have built into their employ...

    Darby, J. [Department of Energy, Oak Ridge, TN (United States)

    1997-02-01

    In this article the author discusses the application of a rock crusher as a means of implementing cost savings in the remediation of FUSRAP sites. Transportation and offsite disposal costs are at present the biggest cost items in the remediation of FUSRAP sites. If these debris disposal problems can be handled in different manners, then remediation savings are available. Crushing can result in the ability to handle some wastes as soil disposal problems, which have different disposal regulations, thereby permitting cost savings.

  7. Do Medicaid home and community based service waivers save money?

    Science.gov (United States)

    Harrington, Charlene; Ng, Terence; Kitchener, Martin

    2011-10-01

    This article estimates the potential savings to the Medicaid program of using 1915c Home and Community Based Services (HCBS) waivers rather than institutional care. For Medicaid HCBS waiver expenditures of $25 billion in 2006, we estimate the national savings to be over $57 billion, or $57,338 per waiver participant in 2006 compared with the cost of Medicaid institutional care (for which all waiver participants are eligible). When taking into account a potential 50% "woodwork effect" (for people who might have refused institutional services), the saving would be $21 billion. This analysis demonstrates that HCBS waiver programs present significant direct financial savings to Medicaid long-term care (LTC) programs.

    Energy savings seems to be the most environmentally benign element in an energy policy. The paper is a reflection on the work on saving energy both by improving technology and by adapting human daily behaviour. A simple model is suggested for the energy chain which converts the primary energy all...... the way into human satisfaction via energy services. Results of various analyses and field experiments show saving potentials for electricity of 50 - 80 per cents. Barriers for implementing these technical saving options are discussed. Also the necessity and potentials for changing behavioural or life...

  13. Macroeconomic determinants of savings in Egypt "Statistical Model"

    Directory of Open Access Journals (Sweden)

    Hanaa Abdelaty Hasan Esmail

    2014-07-01

    Full Text Available Like lot of countries, aggregate consumption constitutes a major portion of Gross Domestic Product (GDP in Egypt. Consumption decisions determine savings decisions. In long term growth literature, differences in long term growth had been explained to a large extent by differences in the rates of savings which also determine a country’s investment in productive capacity, human capital and socio-economic infrastructure. In this study, we analyse macroeconomic determinants of savings in Egypt using Ordinary multiple regression. Our results indicate that national savings rate is positively related with real GDP growth rate. This suggests that saving is a positive function of income. The evidence suggests that national savings rate is negatively related with federal debt growth and inflation. This hints towards crowding out of private sector investment through decline in savings rate as a result of government’s indebtedness. Finally, negative association between savings rate and inflation implies that the consumer is rational and makes decisions based on his perceptions when it comes to allocating the lifetime resources over the period of his life. Increase in inflation dampens the incentive to save and people respond rationally which is made evident by the negative sign on inflation coefficient in our model.

    Rotary instead of percussion adoption of drilling in the underground Akouta mine (Niger) has been the cause of important savings in blasting and bolting operations. Other savings affect capital expenditures and indirect savings are coming from better working conditions. For blast holes drilling and bolting, spare parts expenditures are 2.4 times lower with rotary drilling. Drilling rods are cheaper and last longer with rotary drilling. A rotary equipped Jumbos fleet is cheaper to maintain and is 18% more available, due to less mechanical and other breakdowns.

    All radiation doses come out as a result of dose rate and exposure time, and the main part of the occupational exposure is caused during outages. While every reasonable attempt should be made to lower the dose rates, the other factor, the exposure time, may not be forgotten. The paper presents possible ways of saving man-hours in the controlled zone by outage planning strategy. And every saved man-hour means a saved radiation dose. At Loviisa NPS also some special architectural arrangements contribute to shortening the outage time, thus saving doses

    The objective of this project is to explore the energy savings potential of maximizing furnace and distribution system performance by adjusting operating, installation, and distribution conditions. The goal of the Iowa HVAC System Adjusted and Verified Efficiency (SAVE) program is to train contractors to measure installed system efficiency as a diagnostic tool to ensure that the homeowner achieves the energy reduction target for the home rather than simply performing a tune-up on the furnace or having a replacement furnace added to a leaky system. The PARR research team first examined baseline energy usage from a sample of 48 existing homes, before any repairs or adjustments were made, to calculate an average energy savings potential and to determine which system deficiencies were prevalent. The results of the baseline study of these homes found that, on average, about 10% of the space heating energy available from the furnace was not reaching the conditioned space. In the second part of the project, the team examined a sample of 10 homes that had completed the initial evaluation for more in-depth study. For these homes, the diagnostic data shows that it is possible to deliver up to 23% more energy from the furnace to the conditioned space by doing system tune ups with or without upgrading the furnace. Replacing the furnace provides additional energy reduction. The results support the author's belief that residential heating and cooling equipment should be tested and improved as a system rather than a collection of individual components.

    Due to the amount of materials and parameters that are included in the calculations of cooling spaces in buildings in real scale are very costly, the scale test modules coupled to air conditioner systems are used to obtain their electrothermal behavior. The test modules quantify the electrical energy consumption of each module considering test materials. A transitory theoretical thermal model is analyzed. It describes the thermal behavior of the scale test modules varying the materials of the roofs and glazing of windows, this results allow uns to establish a criteria of what materials can be used in buildings. Additionally a steady state theoretical electrothermal model is presented. This model calculates the electrical energy consumption to maintain the conditions of comfort at the interior of the test modules, that consider the variation of the mentioned materials. The experimentation is developed exposing the scale test modules coupled to air conditioners to the direct solar radiation, recording: the consumption of electric power of air conditioners, the solar radiation incident on test roofs and test windows, the interior temperatures of the modules, the interior and exterior temperature of the test roofs, the ambient temperature, and the speed of the wind. The results obtained comparing the electrical power consumption of the measured and the electrical power consumption calculated present a difference of 16%. The electrical energy savings observed with the theoretical electrothermal model are: 1) Changing only clear glass by sun filter glass it can be achieved savings up to 14.5% for the small beam and small vault pottery and 12.4% for the monolithic pottery; and 2) Changing only clear glass by sun reflector glass it can be obtained savings up to 28.1% for the small beam and small vault pottery and up to 16.8% for the monolithic pottery. The greater detected electrical energy saving was for substitution monolithic pottery with clear glass by the small beam

    The impact of an aging population on escalating US healthcare costs is influenced largely by the prevalence of chronic disease in this population. Consequently, preventing or postponing disease onset among the elderly has become a crucial public health issue. Fortunately, much of the total burden of disease is attributable to conditions that are preventable. In this paper, we address whether well-designed health promotion programs can prevent illness, reduce disability, and improve the quality of life. Furthermore, we assess evidence that these programs have the potential to reduce healthcare utilization and related expenditures for the Medicare program. We hypothesize that seniors who reduce their modifiable health risks can forestall disability, reduce healthcare utilization, and save Medicare money. We end with a discussion of a new Senior Risk Reduction Demonstration, which will be initiated by the Centers for Medicare and Medicaid Services in 2007, to test whether risk reduction programs developed in the private sector can achieve health improvements among seniors and a positive return on investment for the Medicare program.

    2016-11-01

    In the current issue of The New Atlantis, Daniel Sarewitz, professor of science and society at Arizona State University, argues that science is broken because it is managed and judged by scientists themselves, operating under Vannevar Bush's famous 1945 declaration that scientific progress depends on the "free play of free intellects … dictated by their curiosity." With that scientific agenda, society ends up with a lot of unnecessary, uncoordinated, and unproductive research. To save science, holds Sarewitz, we need to put it in the hands of people who are looking for practical solutions to specific problems. In one article in this issue of the Hastings Center Report (November-December 2016), Kirstin Borgerson poses a question in this same conceptual space: are there too many clinical trials? Other pieces in the issue cover a mix of topics: the lead article addresses some of the challenges that will have to be faced as "artificial organs" become available, a third article looks at how crowdfunding sites like GoFundMe can be used to make public appeals for medical funding, and a special report found in a supplement to the issue offers a round of analysis and recommendations about the provision of medical care to professional football players. © 2016 The Hastings Center.

    This paper discusses some important fundamental issues behind application of renewable energy (RE) to evaluate its impact as a climate change mitigation technology. The discussed issues are the following: definition of renewable energy, concentration of RE by weight and volume, generation of electrical energy and its power at unit area, electrical energy demand per unit area, life time approach vs. layman approach, energy return time, energy return ratio, CO2 return time, energy mix for RES production and use, geographical distribution of RES use, huge scale of energy shift from RES to non-RES, increase in energy consumption, Thermodynamic equilibrium of earth, and probable solutions for energy future of our energy and environmental crisis of today. The future solution (that would enable to human civilization further welfare, and good living, but with lower release of CO2 in atmosphere) may not be only RES. This will rather be an energy mix that may contain nuclear energy, non-nuclear renewable energy, or fossil energy with CO2 sequestration, efficient energy technologies, energy saving, and energy consumption decrease.

    2008-01-01

    Each year, millions of people worldwide are affected by disasters, underscoring the importance of effective relief efforts. Many highly visible disaster responses have been inefficient and ineffective. Humanitarian agencies typically play a key role in disaster response (eg, procuring and distributing relief items to an affected population, assisting with evacuation, providing healthcare, assisting in the development of long-term shelter), and thus their efficiency is critical for a successful disaster response. The field of disaster and emergency response modeling is well established, but the application of such techniques to humanitarian logistics is relatively recent. This article surveys models of humanitarian response logistics and identifies promising opportunities for future work. Existing models analyze a variety of preparation and response decisions (eg, warehouse location and the distribution of relief supplies), consider both natural and manmade disasters, and typically seek to minimize cost or unmet demand. Opportunities to enhance the logistics of humanitarian response include the adaptation of models developed for general disaster response; the use of existing models, techniques, and insights from the literature on commercial supply chain management; the development of working partnerships between humanitarian aid organizations and private companies with expertise in logistics; and the consideration of behavioral factors relevant to a response. Implementable, realistic models that support the logistics of humanitarian relief can improve the preparation for and the response to disasters, which in turn can save lives.

    A Canadian rope shovel dipper prototype was tested at the Suncor oil sands operations in May 2005. The 3 cubic yard JPi 2005 series dipper was designed by JPi, a geo-industry engineering consultant firm. The new design minimizes shovel dipper wear and resistance while digging at a rock face. This simple concept could offer major savings for mine operators. The main feature of the shovel dipper is its shape. Rather than having a straight-lined profile, the lip to latch keeper is curved to match the range of motions of the machine itself. This provides optimum penetration angles with minimum resistance when digging, thereby increasing productivity while eliminating heel wear. The dipper was originally designed to dig softer materials, but can actually be used to dig or scoop any material from blasted hard rock to the softest oil sand. The dipper is also more open at the door than at the lip allowing the oil sand to naturally flow out of the dipper upon release. The prototype was demonstrated to an industry-wide audience in May 2005 on a recently rebuilt 1949 Dominion 500 shovel. Preliminary results indicate that the design is meeting the expectations of the designer. However, more tests are scheduled and JPi will continue to seek collaborations and partnerships with mining operations to produce and test a 75 cubic yard version of the dipper for use with modern shovels. 2 figs.

  12. Daylight savings time and myocardial infarction.

    Prior research has shown a transient increase in the incidence of acute myocardial infarction (AMI) after daylight savings time (DST) in the spring as well as a decrease in AMI after returning to standard time in the fall. These findings have not been verified in a broader population and if extant, may have significant public health and policy implications. We assessed changes in admissions for AMI undergoing percutaneous coronary intervention (PCI) in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2) database for the weeks following the four spring and three fall DST changes between March 2010 and September 2013. A negative binomial regression model was used to adjust for trend and seasonal variation. There was no difference in the total weekly number of PCIs performed for AMI for either the fall or spring time changes in the time period analysed. After adjustment for trend and seasonal effects, the Monday following spring time changes was associated with a 24% increase in daily AMI counts (p=0.011), and the Tuesday following fall changes was conversely associated with a 21% reduction (p=0.044). No other weekdays in the weeks following DST changes demonstrated significant associations. In the week following the seasonal time change, DST impacts the timing of presentations for AMI but does not influence the overall incidence of this disease.

  13. Does Daylight Savings Time encourage physical activity?

    Extending Daylight Savings Time (DST) has been identified as a policy intervention that may encourage physical activity. However, there has been little research on the question of if DST encourages adults to be more physically active. Data from residents of Arizona, Colorado, New Mexico, and Utah ages 18-64 who participated in the 2003-2009 American Time Use Survey are used to assess whether DST is associated with increased time spent in moderate-to-vigorous physical activity (MVPA). The analysis capitalizes on the natural experiment created because Arizona does not observe DST. Both bivariate and multivariate analyses indicate that shifting 1 hour of daylight from morning to evening does not impact MVPA of Americans living in the southwest. While DST may affect the choices people make about the timing and location of their sports/recreational activities, the potential for DST to serve as a broad-based intervention that encourages greater sports/recreation participation is not supported by this analysis. Whether this null effect would persist in other climate situations is an open question.

  14. Calculating cost savings in utilization management.

    A major motivation for managing the utilization of laboratory testing is to reduce the cost of medical care. For this reason it is important to understand the basic principles of cost accounting in the clinical laboratory. The process of laboratory testing includes three distinct components termed the pre-analytic, analytic and post-analytic phases. Utilization management efforts may impact the cost structure of these three phases in different ways depending on the specific details of the initiative. Estimates of cost savings resulting from utilization management programs reported in the literature have often been fundamentally flawed due to a failure to understand basic concepts such as the difference between laboratory costs versus charges and the impact of reducing laboratory test volumes on the average versus marginal cost structure in the laboratory. This article will provide an overview of basic cost accounting principles in the clinical laboratory including both job order and process cost accounting. Specific examples will be presented to illustrate these concepts in various different scenarios. © 2013.

  15. Use a defibrillator, save a life

    With the work for Long Shutdown 1 looming on the horizon, the CERN Fire Brigade is anticipating a heavy workload: more people working at CERN means more call-outs. So the more trained first-aiders around to help out before the paramedics arrive, the better. Would you know what to do in a medical emergency?   It could happen at any time: two colleagues are having a coffee at work, when one suddenly clutches his or her chest and falls to the floor unconscious. What would you do? Run to find a first-aider? Call the ambulance and wait, finishing your coffee? Neither response is entirely correct. On Monday 11 June in Building 40 the CMS safety group, in collaboration with the Fire Brigade and the Medical Service, demonstrated the recommended, potentially life-saving response to cardiac arrest (see the video), including the correct use of a defibrillator, ten of which were recently installed in key CERN locations (the Bulletin reported).     “In countries where...

  16. STATE BENEFIT - INCENTIVE FOR SAVINGS AND INVESTMENTS

    Directory of Open Access Journals (Sweden)

    Full Text Available The present paper aims to be an answer for many investors with financial powers, seeking financial instruments with yields above the average interest rate on the banking market. One such tool, fairly new to the Romanian banking market, has been implemented for about 14 years, and is becoming more and more an instrument for savings, investments or an aid in the purchase of a house. Regardless of the perspective presented in the table of contents, the incentive for choosing such a banking product is the state benefit, a form through which the administration creates the conditions necessary to update and develop the housing system. In the thesis I have explored aspects of legislation which, in such a short period of time have changed 3 times the amount and the method of granting the state benefit and I have also tried a quick historical and legislative evolution of the implementation of Bauspar system throughout Europe. It is pointed out that in comparison with other countries - namely Germany, England or Austria where this system is well-known and has been implemented for over 120 years - Romania is at the beginning of its journey, a fact proved especially by the number of signed contracts in relation to the number of inhabitants.

    The application of Virtual Reality for training in radiological environments allows the planning analysis and training in tasks which will be performed later in a real environment, saving doses to the real workers. There are many advantages of using VR in the training field comparing with a traditional training based on entries to the radiological areas and 2D studies: The application of the VR to the nuclear industry will provide in a middle period a more efficient training in radiological environments, giving more fidelity to the real world, enforcing the spatial skills and the active learning and allowing the visualization of the radiation field and the more suitable routes. TECNATOM has been working in VR field through several to test the adequacy of this methodology. Specifically, the SIMU2 project has been developed. This is a Virtual Reality highly flexible based software tool which allows for the simulation of human tasks in radiological environments, providing dosimetric information in all the points of the environment as well as the doses received by the workers during the simulated tasks performance. This application can be used as a support tool in training courses, to train the operators who will perform the real operation. Besides, the system allows the trainer to enter comments and explanations for each selected action or for the complete task. (Author) 8 refs.
