    Full Text Available El presente trabajo tuvo como objetivo estudiar los factores que intervienen en la selección técnico económico de goteros. En el estudio fueron utilizados emisores autocompensados y no autocompensados, considerando a los aspectos técnicos como porcentaje de suelo humedecido, número de emisores por planta y coeficiente de uniformidad y precio y la presión de operación del emisor como aspectos económicos. Los resultados muestran que la presión de operación de los emisores es el factor más importante a considerar en la selección, ya que para valores más bajos de presión de operación se obtuvieron menores valores de costo total anualizado, independiente del tipo de gotero. En general, los goteros no autocompesados presentaron valores de costo anualizado menores, para un rango de presión similar. Finalmente el análisis tecnico-económico en la selección de emisores es un procedimiento importante.The objective of this research was to study the parameters that affect the technical-economical selection of emitters. In the study compensated and non-compensated emitters were used. The technical aspects considered were: percentage of wetted soil, number of emitters per plant and the uniformity coefficient as well as price and operation pressure for economic aspects. The results shows that the operation pressure of emitters is the most important factor to be considered in the selection , with smaller values of pressure giving lower total annual cost, independently of the type of emitter. In general, the non-compensated emitter shows lower annual cost values than for compensated emitters, for a similar range of pressures. Finally the technical-economical analysis in the emitter selection is an important procedure.

    scientifica e tecnologica internazionali sono stati sempre piu` indirizzati allo sviluppo di nuovi processi di lavorazione ed alla valorizzazione, al recupero es alla trasformazione di materie prime alternative e, soprattutto, rinnovabili. A tale riguardo, gia` da alcuni anni, si sta affermando la consapevolezza da parte degli imprenditori della carta di rispondere ad una triplice esigenza: quella dovuta alle normative antinquinamento sempre piu` severe, quella relativa all`opinione pubblica sensibile alla tutela ambientale e quella di mercato legata all`acquisizione di un `vantaggio competitivo` nei confronti della concorrenza. Il presente lavoro si inserisce in tale scenario realizzando una valutazione tecnico-economica dell`applicazione in ambito industriale della tecnologia di steam-explosion ed delle biomasse ligno-cellulosiche, intese sia come scarti di lavorazione agro-industriali che nella piu` recente accezione di colture industriali (specie C{sub 4}, C{sub 5}) specificatamente destinate al recupero di aree marginali (set aside) e successivo utilizzo a fini produttivi ed energetici. Nel contempo, viene preso in esame l`introduzione del processo di trattamento di Steam Explosion per un conveniente inserimento in cicli di produzione industriale, con particolare riferimento a quelli della carta.

    It is presented an study of the operational impact into a briquettes factory produced by the introduction of a torrefaction process. Through costs analysis it is shown that for a briquettes factory of 1.200 ton/year capacity, it is possible to increase Operational Profits and decrease the Break Even Point in 15.7 % when a torrefaction reactor is introduced into the manufacturing line. So, it is possible to insure that torrefaction increase the overall system efficiency without increasing yearly production since the number of 'biomass fuels' is increased enabling operation in other markets. This study also shows that torrefaction improves briquettes quality allowing access to the comparatively smaller consumer market still unreached by biomass briquets. (author)

    The feasibility of the development in Venezuela of a hydroelectric/hydrogen energy system (HHES) was studied. The application of this system is intended for rural sectors in the country with no available permanent and safe energy services. The study was conducted by developing and later simulating a mathematical model for each of the components of the energy system: transformation, storage, transport, distribution and final use. Structurally, the models are composed of an energy sub-model and a cost sub-model. The HHES model as a whole is obtained from the connection of the models and the components. The simulation is performed for operating conditions and parameter values that are most favorable for the proposed use, with the same temporal period in all cases. The results indicate that the annual production of H{sub 2} must increase in order to satisfy the growing energy needs of the rural study population. The total annual costs of the HHES decreased during the study period, primarily due to a decrease in the costs of the final use component, which indicates the behavior of total costs. A comparison of the results obtained with those from the literature demonstrate interest in the proposed system given the ideal economic and environmental conditions provided to the zone selected, primarily due to the availability of inexpensive hydroelectric energy in the country. The current feasibility of the development of the HHES is shown, as compared to the option of supplying electric energy to rural population centers via traditional electric installations.

    Full Text Available A viabilidade de escleródios de Sclerotinia sclerotiorum foi avaliada durante oito meses em três solos de Cerrado cultivados. Escleródios produzidos "in vitro", mantidos em invólucros de náilon perfurados, foram enterrados a 5 cm de profundidade, em solos previamente fumigados ou não fumigados com brometo de metila. Após 10 dias de incubação, os escleródios foram examinados quanto à viabilidade e a presença de fungos antagônicos. A viabilidade foi estimada através do número de escleródios germinados 7 dias após plaqueamento em meio semi seletivo Neon-S. A viabilidade dos escleródios variou com o solo de Cerrado. Escleródios incubados em solos não fumigados com brometo de metila apresentaram menor viabilidade e maior presença de fungos antagônicos, indicando que estes solos contêm elementos supressivos de origem biológica. A viabilidade dos escleródios foi relacionada negativamente com a população de alguns microorganismos de solo. Nos tratamentos de maior incidência de Trichoderma spp. observou-se menor viabilidade de escleródios e solos fumigados suprimiram fortemente a ocorrência deste antagonista.

    This study aims to examine the technical feasibility and financial cost for a cogeneration system in a company in the tertiary sector. For this, was studied the electromechanical and thermal characteristics of a shopping center, as well as the technologies associated with the proposed cogeneration system. From the modeling of electric and thermal loads it was determined the system of operation for the system and the possible surplus energy generated. For the analysis of economic viability compare operating costs without cogeneration and with the alternative of cogeneration chosen. Among the calculations are the costs of investment and operation of the system. Was encountered the attractiveness of a cogeneration system, which uses natural gas as fuel for alternative engines and, in turn, reject heat to the absorption chillers. The idealized cogeneration system was also evaluated positively with a view to qualification required for participation in policies to encourage the rational use of energy resources. (author)

    Full Text Available Un alimento funcional contiene en su formulación una o más sustancias que generan bienestar a la salud humana como son probióticos, prebióticos y ácidos grasos, entre otros. En los alimentos funcionales los microorganismos probióticos deben permanecer viables y activos en el alimento y durante el pasaje gastrointestinal, para garantizar su potencial efecto benéfico en el huésped. En el presente estudio se evaluó la viabilidad de la levadura probiótica Saccharomyces boulardii tanto de forma libre como encapsulada bajo condiciones de acidez, adaptada a un queso fresco. Método: La levadura fue expuesta en el alimento tanto en forma libre como encapsulada. Los materiales usados para encapsular fueron una mezcla de alginato de sodio, inulina y mucílago de nopal (Opuntia ficus-indica. Para la liberación del microorganismo, el estudio se realizó a pH de 2.0 y 6.5, simulándose las condiciones de acidez de estómago y colon respectivamente, a diferentes tiempos de exposición de 0, 60, 120 y 180 min. Resultados: A pH de 2.0 se observó mayor pérdida en la viabilidad del probiótico en forma libre, la cual fue de 23.72, 27.03 y 33.02 % respectivamente, con respecto a la viabilidad inicial; cuando el microorganismo se adicionó al queso en forma encapsulada, su pérdida de viabilidad a los mismos tiempos de exposición fue de 5.74, 14.24 y 18.81%, manteniendo mayor supervivencia. Por otra parte, a pH de 6.5 el probiótico libre en el alimento mostró una pérdida de viabilidad de 2.23, 3.50 y 5.94%, en cambio de forma encapsulada la pérdida de viabilidad fue de 0.95, 2.20 y 3.03%, respectivamente, observándose mayor supervivencia que en estado libre. Conclusión: El queso fresco mantuvo viable el nivel de supervivencia de Saccharomyces boulardii, particularmente cuando fue adicionado en forma encapsulada comparado a cuando fue incorporado en estado libre.

    Full Text Available En el artículo se observa el impacto que tiene la oferta bancaria y crediticia, frente a las necesidades de recursos para inversión del sector agropecuario en Colombia. La disposición de recursos financieros aptos para el sector agropecuario, constituye uno de sus principales cuellos de botella. Los análisis exploratorio y descriptivo fungen como fundamento metodológico para el desarrollo temático del escrito. La necesidad de liquidez e irrigación de recursos son tomados como puntos de quiebre para el sector, y, a la vez, como no se conoce claramente el impacto del sector financiero frente a las necesidades de crédito, se deja la viabilidad del mismo a las condiciones cíclicas del mercado.

    A scenario is a logical and congruent narration on the future, which describes the future in terms of the consequences on the surroundings of tendency forces (descriptive scenario) or as a result of caused changes (normative scenario). Unlike an econometric projection, that fundamentally considers economic forces, a scenario takes into consideration the impact of political, technological, social and legal forces, in addition to the economic ones, and the uncertainty of the future can be covered using several different scenarios. The construction of scenarios constitutes an extremely useful tool for long term planning of and the design of governmental policies for the energy sector. In this work an investment to twenty-five years in the national energy sector, with a long term planning of using scenarios, the design of a policy of the possible savings and bases for the future technological development and investigation effort is estimated. [Spanish] Un escenario es una narracion logica y congruente sobre el futuro, la cual describe el futuro en terminos de las consecuencias sobre el entorno de fuerzas tendenciales (escenario descriptivo) o como resultado de cambios provocados (escenario normativo). A diferencia de una proyeccion econometrica, que fundamentalmente considera fuerzas economicos, un escenario toma en consideracion el impacto de fuerzas politicas, tecnologicas, sociales y juridicas, ademas de las economicas, la incertidumbre del futuro se puede cubrir utilizando varios escenarios distintos. La construccion de escenarios constituye una herramienta sumamente util para la planeacion de largo plazo y el diseno de politicas gubernamentales para el sector energetico. En este trabajo se estima una inversion a veinticinco anos en el sector energetico nacional, con una planeacion de largo plazo utilizando escenarios, el diseno de una politica los posibles ahorros y la base para el futuro desarrollo tecnologico y esfuerzo de investigacion.

    Current scenario indicates that renewable energy sources are expected to play an increasingly important role in the world energy matrix, mainly due to a potential reduction of fossil fuel reserves and environment issues. In this context, the use of alternative energy sources, specifically biomass briquettes, shows up as a great opportunity. However, it is known that an economic feasibility assessment for the project depends on decision-making factors such as equipment, labor and material implementation. All costs and investments were calculated. A company headquartered in the city of Tiete, Sao Paulo State, analyzed the total costs of implementing a high density briquette factory. Tow scenarios were considered. In scenario 1, with tax exemption, the Net Present Value (NPV) is positive and the Intern Rate of Return is 16,9%, is an economic feasible scenario. Scenario 2, with no tax exemption, is not economically feasible, the NPV is negative and the Intern Rate Return is 13,9%, lower than 15.0% of the minimum rate of investor attractiveness. (author)

    Full Text Available L’Autrice si propone di tracciare la genealogia della posizione neoliberale, partendo soprattutto dai testi di Gary Becker. Il pensiero economico neoliberale è posto in relazione con la rivoluzione scientifica e l’operazione di matematizzazione della natura che da essa scaturisce. Questo percorso porterà poi a Jeremy Bentham, il cui sistema è spesso visto come antesignano degli studiosi neoliberali. Secondo la tesi sostenuta dall’Autrice, il neoliberalismo presenta il proprio sguardo come una neutra e scientifica descrizione del reale, sennonché in tale mossa si annida pur sempre una tendenza normativa. È così che gli economisti neoliberali elaborano un sistema che è altresì prescrittivo, proponendo un modello che si pone sul piano politico; modello il quale viene qui designato con il nome di «utopia economica».

    RESUMEN: Los estudios de viabilidad tienen por objeto hacer un análisis económico teórico de un hipotético negocio minero que se establece en virtud de la existencia de un yacimiento. Prestaremos atención a un primer paso que podríamos denominar prefactibilidad, teniendo en cuenta que en una primera etapa no se deben emplear demasiados esfuerzos en el tema de los costes, donde las desviaciones, aunque pueden ser considerables son más o menos análogas a otros tipos de empresa.

    Diffusion of hydrogen as an energetic vector meets with a lot of obstacles that don't depend on available raw material, but on hydrogen combination with other elements. It is necessary, therefore, to separate hydrogen picking out the available different technologies to have different pure hydrogen of variable quantities. Besides, its diffusion as fuel is limited because of the great production cost compared to fuels sprung from petroleum. Hydrogen used on a large scale could have advantages on the environment and occupation, but there are economic and politic obstacles to limit its diffusion. Future of economic system, based on hydrogen as the main energetic vector, will depend on the programme that national and international qualified governing bodies will be able to do. [Italian] L'articolo analizza l'uso dell'idrogeno come risorsa dal punto di vista tecnico ed economico. Si discute la relazione con i programmi che governi nazionali sapranno mettere in campo per il suo sfruttamento.

    Physalis peruviana L. y P. philadelphica Lam. son dos solanáceas de importancia económica para Colombia y México. Existen grandes vacíos en el conocimiento de la palinología y viabilidad polínica de estas dos especies. Por lo tanto, el objetivo del presente trabajo fue caracterizar su grano de polen y determinar su viabilidad bajo condiciones con­trastantes de climas frío y cálido. La caracterización del polen se hizo a través de la técnica de acetólisis (en microscopía de luz y por microscopía electrónica de barrido. Se determinaron variables como el eje polar, el diámetro ecuatorial, el número, posición y carácter de las aberturas (NPC, lado de apocolpo/apoporo, forma polínica, contorno en vista polar y en vista ecuatorial, tipos de área polar y de abertura, y el tipo polínico. Estas variables permitieron descri­bir y caracterizar el grano de polen de los genotipos estudiados. Con el empleo de técnicas de fijación de flores en antesis y tinción con acetocarmín, se hizo un análisis de la viabilidad polínica bajo microscopía de luz. Las dos especies presentan un grano de po­len zono-tricolporado, de tamaño mediano en P. pe­ruviana y pequeño en P. philadelphica. Los ambientes marginales reducen la viabilidad del polen pero no afectan su fertilidad.

Sin embargo otras moléculas relacionadas estructuralmente con dichos derivados, se han reportado como candidatos terapéuticos y otras de ellas se incluyen en alimentos de consumo humano. Objetivo: el presente trabajo evalúa el efecto sobre la viabilidad celular de una nueva serie de espiroesteroides sintéticos derivados de la diosgenina, en células tipo neurales PC12. Métodos: la viabilidad de los cultivos de PC12 se determinó mediante el ensayo de MTT y se calcularon descriptores moleculares teóricos como la lipofilicidad (logP virtual y la superficie de área polar (SAP, con el objetivo de establecer relaciones estructura-actividad. Resultados: nuestros resultados demuestran que solo el acido taurodesoxicólico disminuye de manera significativa la viabilidad celular. Más aun, dicha molécula presenta valores menores y mayores de logP virtual y SAP, respectivamente, respecto al resto de los esteroides de la serie. Conclusiones: los resultados anteriores avalan el estudio del acido taurodesoxicólico como potencial inhibidor de la proliferación celular y al resto de las moléculas de la serie como candidatos neuroprotectores a evaluar en esta misma línea celular y dosis de tratamiento.

    Full Text Available O objetivo deste trabalho foi determinar o modo de reprodução e as condições para testes de viabilidade in vitro de pólen de três espécies de jabuticabeira (Plinia cauliflora, P. trunciflora e P. jaboticaba. Avaliaram-se a frutificação efetiva em ramos ensacados e não ensacados, e aspectos da morfologia floral. A viabilidade de pólen foi avaliada em meio de cultura com e sem ácido bórico, com pólen coletado em diferentes períodos após antese. A germinação de pólen de seis genótipos foi quantificada antes e após armazenamento. P. trunciflora e P. jaboticaba são autocompatíveis, porém os polinizadores aumentam a frutificação. A espécie Plinia cauliflora necessita de agentes polinizadores para frutificar, pois apresenta flores com maior distância estigma-anteras que as outras duas espécies, o que impede a autofecundação passiva. A adição de ácido bórico no meio de cultura aumenta a germinação in vitro de pólen de jabuticabeira. A viabilidade do pólen é máxima após seis horas da antese. É possível a conservação do pólen por até 90 dias em congelador (-18ºC, desde que apresente alta germinação inicial (maior que 80%. Esses resultados auxiliam no planejamento de cruzamentos em jabuticabeira.

    La importancia de los cultivos celulares humanos continúa expandiéndose, en especial en el campo de la bioingeniería de tejidos. Con el fin de establecer mejores criterios de selección en la obtención de tejido renal postmortem, se estudiaron 111 neonatos de < 3 días de edad, fallecidos en la sala de Cuidados Intensivos del Recién Nacido (CIRENA y 22 mortinatos de la sala de partos del Hospital Universitario del Valle (HUV en Cali, Colombia, entre enero 1 y diciembre 31 de 1995. Se consideraron los antecedentes maternos y fetales, en busca de variables que determinen una mejor viabilidad celular renal postmortem (VCRP. Además, se hizo un estudio del estado microbiológico de los neonatos postmortem y de los mortinatos mediante el examen de sangre y células para conocer la incidencia en estos de infecciones bacterianas y virales.

    De los 133 casos estudiados, 115 (86% fueron de bajo peso al nacer (BPN, vgr. 500 a 2,500 gramos y los 18 (14% restantes fueron de peso adecuado al nacer (PAN >2,500 gramos. De 13 clases de diagnóstico registrados como antecedentes maternos, los seis más frecuentes fueron: ruptura prematura de membranas (RPM – 20%, PRE-eclampsia/eclampsia (PE – 13%, corioamnionitis (CA – 11%, infección urinaria (IU – 11%, placenta previa (PP – 9% y vaginitis (V – 8%. De los ocho diagnósticos registrados en los neonatos, los dos más frecuentes fueron el síndrome de dificultad respiratoria (SDR y la enfermedad de membrana hialina (ME -73%.

    Se pudo observar que la VCRP total fue de 65%, siendo mayor en los casos con BPN (69% que en los de PAN (39%. Independientemente de los antecedentes maternos se observó una VCRP de 70% y 77% en los casos con diagnóstico de SDR y EMH, respectivamente. Por otra parte, se obtuvo la mayor VCRP en los casos con diagnóstico materno de PP (83%. Aunque por el bajo número de casos expuestos en el presente estudio estas diferencias no demostraron significancia estad

    Full Text Available En los últimos años se han realizado en Costa Rica algunos esfuerzos para desarrollar normativa urbana que facilite la intervención dentro de las ciudades existentes, con el fin de revitalizar los centros urbanos y atraer nuevamente a la población que por diversas causas renunció a vivir en la ciudad. Las estrategias de Renovación Urbana han desempeñado un papel importante en las transformaciones socio-espaciales que han experimentado muchas ciudades del mundo, las cuales incorporan herramientas novedosas para intervenir dentro del entorno construido y contemplan una serie de instrumentos que permiten corregir las tendencias negativas que genera el modelo de ciudad dispersa, y a su vez devolver la funcionalidad y el atractivo a sectores estratégicos con el fin de construir un nuevo modelo de ciudad más sostenible e inclusiva. El presente artículo tiene como propósito analizar las posibilidades que existen en el país para implementar estrategias de renovación urbana, tomando como marco base la legislación urbana existente. Con el fin de evidenciar este supuesto se analiza la normativa vigente y se pone en evidencia como dicha legislación faculta a los municipios para ejercer competencias en la planificación urbana y el ordenamiento de su territorio. Se da un énfasis particular a la viabilidad para desarrollar e implementar estrategias de renovación urbana en la escala local, la cual se fundamenta en la Ley de Planificación urbana 4240 y se fortalece con los avances más recientes que se han dado en el país en materia de actualización normativa.

    Analyses the most important economic parameters of the main pyrolysis processes. Considers the markets available for semi-coke and tars. Concludes that no single technology or process has clear advantages over the others because all depends on the type of coal being used and the purpose for which the end product is to be used. Refers to studies carried out in Canada and the USA on the same subject and reports their findings. Concludes optimistically that coal pyrolysis shows promise of being economically viable in the future because although initially, costs reflect the high financial outlay necessary to begin operations, after a certain period, these costs fall and the end product can be sold at a lower price. A further point in favour of pyrolysis is that coal prices are likely to rise more slowly than oil prices. 5 refs., 8 tabs.

    Full Text Available El cooperativismo agrario ha estado ligado desde sus orígenes al sector de las frutas y hortalizas, sector que arrastra desde hace años una problemática de carácter estructural, incrementada, sobretodo en el caso de la fruta, por las graves crisis de precios, la saturación de los mercados y una competencia creciente de las importaciones de terceros países. En este difícil marco, los productores deben seguir invirtiendo para mantener la competitividad y la rentabilidad de sus explotaciones, y las cooperativas, por su importancia económica, deben acometer políticas que permitan garantizar la viabilidad de dicho sector. En el presente trabajo realizamos un análisis del sector cooperativo frutícola catalán, con el fin de detectar sus puntos fuertes y débiles, así como posibles carencias y demandas. Las conclusiones muestran que las cooperativas son importantes en el sector de la fruticultura, debido sobretodo a su contribución activa a la conservación del territorio y su papel generador de empleo en numerosas zonas rurales. Pero se hace necesario la adopción de firmes decisiones y la implantación de medidas de apoyo que permitan garantizar los intereses de los socios y las necesidades de los consumidores./ The agricultural cooperatives have been linked from the origins to fruit and vegetable sector. This sector dragged on for years a structural problem, increased, especially in the case of fruit, for serious price crisis, the market saturation and increasing competition. In this difficult context, producers must keep investing to maintain competitiveness and profitability. The cooperatives, by their economic importance, should undertake policies to ensure the viability of this sector. In this paper we do an analysis of Catalan fruit cooperative sector, to identify their strengths and weaknesses, and possible deficiencies and demands. The findings show that cooperatives are important in the fruit growing sector, mainly due to their

    Full Text Available Uma chave para o entendimento da expansão da abelha africanizada (Apis mellifera é distinguir esta abelha agressiva de sua equivalente européia. Técnicas de identificação atual têm um grau de sucesso, mas cada método tem seu próprio conjunto de problemas, tornando-se proibitivo sua adoção e uso em larga escala. Este estudo examinou aspectos do estado excitatório central, persistência de mobilidade de apêndices e viabilidade da ferroada após decapitação como ferramenta na distinção entre essas duas raças. O estado excitatório central não foi útil na distinção entre a abelha africanizada e a européia; todavia, a mobilidade de apêndices e a viabilidade do ferrão foram significativamente diferentes entre essas duas raças. A mobilidade de apêndices e a viabilidade do ferrão são técnicas úteis na distinção das duas raças e atenua os aspectos relacionados a gastos, aplicação e precisão.

    1994-12-31

    The failure of both democracies and revolutions in Latin America is due to the fact that the State has been trusted with political, economic and social organization, instead of relying on the motivations and capabilities of intermediate associations and the individual members of society. Therefore, the process of change is not just a matter of national decision; it is something that must, and will, take place. Ecuador understands perfectly well the need for reform. Major laws have already been enacted, and a bill for modernization of the State is currently under consideration by congress. The concept of modernization and, therefore, change does not merely imply new laws, simplified procedures or easier operations; it basically means allowing the creative forces of individuals, enterprises and intermediate associations to play a more influential role. As in other Latin American countries, in Ecuador there can be no real modernization, no real change in society without a major revolution in energy and telecommunications. Thus, two important laws have been drafted to demonopolize petroleum and electric power operations and open them up both to national and foreign private sector participation.

    After the end of the PETROBRAS monopoly in Brazil, the country started a new exploratory stage. Until the beginning of the pre-salt researches, the discovery of new oil mature fields was almost impossible. To take back the incentive to new researches about on-shore basins, without affect the focus on the off-shore basins, the Agencia Nacional de Petroleo, Gas Natural e Biocombustiveis (ANP) has been making efforts to increase the segment of oil medium and small size producers, who are called independent producers. To guarantee the good results, ANP has created auctions of mature and original fields of oil. The objective is to attract small and medium companies, so they can contribute to new technology of land exploration. The auctions have brought strength to the independent producers. The aim of this article is to show the case of Quiambina field, which belongs to the Campo-Escola Project, created by ANP in partnership with Universidade Federal da Bahia (UFBA) to revitalize the fields considered as matures, returned by PETROBRAS at the end of its monopoly era. To prove the economic viability of these mature shields, it will be used real values, get in the first four years of production. (author)

This article presents the various types of hydrokinetic turbines that exist and details the technical and economic feasibility of the second generation of hydrokinetic turbines designed by the University of Brasilia. The technical requirements on the selection of hydrokinetic sites, along with the diverse forms of fixing and mooring the turbine in the river are also showed. The economic feasibility of the use of this technology is presented along with the calculation of the generation costs accompanied with an assessment of the different items comprising this cost. At the end, this paper closes with a discussion on the management and operation of decentralized electric energy generation systems with renewable sources, showing that there is a need to design appropriate management mechanisms for this kind of situation, taking into account the specific aspects of its supply and principally of its use.

    This work deals with cogeneration and independent power production and, more specifically, with the feasibility and perspectives of these technologies in the Brazilian sugar-cane industry. In the first part of thesis, cogeneration and independent power production are assessed as decentralised power generation options. Some aspects of these technologies are identified, as the conditions in which they have developed in recent years, world-wide, and how they have been dealt with in the institutional structural changes under way in the public owned electric power sector in several countries. In the second part, the Brazilian sector and the sugar-cane industry are evaluated. The organisational structure of the electric power sector, the reasons of its institutional and financial crises and some structural changes proposals are discussed. In the other hand, the sugar-cane industry is studied according to the following aspects: its expansion in recent years, the concentration of the production, the alcohol production costs and why some degree of production diversification in this industrial branch is desirable. Several technological alternatives that allow a large scale electricity production in the sugar and alcohol sector are examined in the final part of this thesis. A simulation procedure was specially developed in this thesis and applied to a typical sugar and alcohol plant. With the help of this simulation procedure, technical and economic evaluations were carried out and the best alternatives are identified. Finally, their potential was calculated for the sugar-cane industry in the State of Sao Paulo, considering the possible expansion of the sugar and alcohol production and the mills that are amore appropriate to respond for this increase. The large scale electric power generation from sugar-cane by-products is an option that can bring about some advantages for the public owned electric power sector, as well for the sugar-cane one. As a matter of fact, looking

    A cultura do arroz tem se mostrado muito promissora, justificando as ações que objetivam tornar mais eficaz sua produção e distribuição. No Brasil, tendo em vista a dependência externa do trigo, um maior emprego da farinha de arroz em produtos de panificação poderia ser uma alternativa interessante. A importância nutricional deste cereal deve-se a expressiva quantidade de calorias que fornece, aliada ao baixo índice glicêmico, que é responsável pela lenta absorção dos carboidratos e maior sensação de saciedade. Adicionalmente, a farinha obtida do arroz, por não conter glúten, pode ser empregada em produtos de panificação destinados à pessoas com necessidades alimentares especiais, como os celíacos. Além disto, possui substâncias tais como o amido resistente, que tem mostrado efeitos benéficos à saúde, especialmente por auxiliar no trânsito intestinal. Apesar de todos os benefícios socioeconômicos e nutricionais, a utilização da farinha de arroz ainda é modesta. Em função disto, objetivou-se verificar a viabilidade da substituição da farinha de trigo por farinha de arroz na formulação de três produtos (cuquinha de banana, bolo de chocolate e torta salgada, utilizados na merenda escolar de crianças de 3 a 5 anos; para tanto, foi analisada a aceitabilidade, através de técnicas sensoriais; os custos e valores nutricionais das preparações. Constatou-se que as preparações a base de farinha de arroz apresentaram total aceitabilidade por parte das crianças; custos ligeiramente superiores às preparações com farinha de trigo, e valor nutricional vantajoso, demonstrando, de um modo geral, a viabilidade para substituição.

Elas são produzidas, principalmente, pelos gêneros Fusarium, Alternaria, Aspergillus e Penicillium, os quais podem contaminar grãos e cereais, como trigo, milho e soja. Conforme sua natureza e níveis de concentração, micotoxinas podem induzir efeitos tóxicos em animais de produção e humanos. Um estudo in vitro foi realizado para avaliar a susceptibilidade das células linfocitárias de frangos de corte a diferentes concentrações de ocratoxina A, deoxinivalenol e zearalenona. Cada micotoxina foi adicionada ao meio celular em diferentes concentrações (0,001; 0,01; 0,1 e 1μg/mL. A viabilidade celular e atividade de ecto-adenosina desaminase foram analisadas em 24, 48 e 72 horas através de ensaios colorimétricos. Para isso, foram utilizados 0,7x10(5 linfócitos/mL em meio RPMI 1640, suplementado com 10% de soro fetal bovino e 2,5 UI de penicilina/estreptomicina por mL, incubados em atmosfera de 5% de CO2 a 37 °C. Todos os experimentos foram realizados em triplicata e os resultados foram expressos como média e erro padrão da média. Os resultados obtidos demonstraram que tanto ocratoxina A como deoxinivalenol induziram proliferação linfocitária e baixa atividade enzimática in vitro (P0,05. Foi possível correlacionar os dados referentes à viabilidade celular e atividade de ecto-adenosina desaminase, sugerindo que, em concentrações mínimas, as micotoxinas testadas não estimularam a atividade da enzima, que possui ação pró-inflamatória e contribui para o processo de imunossupressão e, portanto, evitando um decréscimo na viabilidade celular. Este é o primeiro estudo feito com OCRA, DON e ZEA sobre linfócitos de frangos de corte em cultivos in vitro na avaliação desses parâmetros.

    Full Text Available Este trabalho avalia a viabilidade técnica e econômica de se implantar um sistema de coleta de águas pluviais em uma instituição de ensino e uma residência, ambas localizadas no município de Campos dos Goytacazes, RJ. A pluviometria da cidade, área de captação e a estimativa do consumo de água não potável foi estimada para a Universidade Candido Mendes e uma residência dimensionada para cinco moradores. O custo de implantação, manutenção e valor da água tratada foi usado para calcular a viabilidade econômica do sistema. A precipitação na década de 2000 é significativamente maior do que na década de 1990. Os quatro primeiros e os dois últimos meses do ano são os mais chuvosos, enquanto que junho a agosto são mais secos. Apesar da água coletada atender a 100% da demanda, o projeto não é economicamente viável na residência. Na universidade, a coleta atenderia a 27% da demanda anual, no entanto, seria economicamente viável. O armazenamento e uso de água pluvial em áreas urbanas colaboram para a preservação do meio ambiente, é uma ferramenta de educação ambiental, evita enchentes, escassez e traz benefícios econômicos devido a redução do consumo de água tratada. Sua implantação em residência poderia ser incentivada com atos governamentais, como a redução de impostos. Para as empresas, além de redução de custos, é um sistema que pode compor o marketing verde, um seguimento de mercado em ascensão.

  16. Private sector participation in power sector in India

    1992-01-01

    The Indian Government is currently thinking of allowing private sector to participate in power sector inviting private sector to generate electricity mainly from coal. The main motivation is resource mobilization from private sector, since the Plan funds are diverted to rural development away from power sector; and yet the massive expansion has to be financed. The paper analyzes the inherent difficulties and contradictions in the Government's proposal, such as co-existence of high cost private power and low cost public power, the potential goal-conflicts of private and public utilities and the constraints in raising finance. It suggests a different model in order to make the privatization proposition feasible. 12 refs

    The carbon dioxide emissions of the Mexican Industrial Sector throughout the period of 1965-2003 are analyzed, in terms of 16 branches of the industrial economic activity, as it is marked by the proposed disintegration of the Sistema de Cuentas Nacionales of the Intituto Nacional de Estadistica, Geografia e Informatica (INEGI) and the National Balance of Energy 2003 (BNE-2003). The CO{sub 2} emissions by the energy use have a behavior very similar to the one of the consumption of the final energy, which reflects that non significant changes in the composition of used fuels have existed. During this period the CO{sub 2} emissions increased 230%. The industrial branches that have shown significant changes in the CO{sub 2} emission are Construction, Bottled Water, Rubber, Cement, Beer and Malta and Chemistry. In order to evaluate the effects of the Activity, Structure, Power Intensity, fuel Mixture of final use and fuel Mixture used in electricity generation the decomposition model of CO{sub 2} is used based on the Laspeyres index. The calculated effects show that the main increase of total carbon dioxide of the SIM is referred to the Activity with an average rate of annual growth (TMCA) of 4.32%; whereas the effect that mitigates more the CO{sub 2} emission is the one described by the power Intensity and is equivalent to a TMCA of -0.85%.

    In the year of 2003 the Brazilian government, as form of to stimulate the demand for natural gas in the country and to promote the success of the investment accomplished in the construction of the pipe line Bolivia-Brazil, it lowered the price of the Bolivian commodity' in US$0,85/MMBTU. In the end of 2005 and mainly in 2006, the current Bolivian president Evo Morales nationalized the energy reservations of your country. To main change it is related to the price of sale of the Bolivian input. The values stipulated in contract they were broken and new negotiations are in process. The maximum capacity of transport of natural gas was reached in 2007. However, before the crisis established due to the measure taken by the government from Bolivia, Brazil suspended the investments in compressors and the projections of increase of this capacity were stagnated. One of the forecasts was to increase in at least more 50% of the current capacity or even in 100% in a more promising scenery. Before this context this research makes the analysis of economical viability regarding the construction of the pipe line Bolivia-Brazil in agreement with three sceneries. The first of them suggests that the investments foreseen in compressors it was stopped and, this way, the pipe line will operate it ties the end of the amortization with your current maximum capacity. The second scenery already suggests that the investments were not interrupted, in other words, the current maximum capacity was overcome in 50%. Similarly to the previous ones, the third scenery makes reference the overrun of the current capacity in 100%. The methodology used for such an analysis it was lent of the financial mathematics and it is treated of the calculation of TIR and of VPL. Both studies show that in agreement with TIR (15%) and VPL the economical viability is satisfactory. The president of PETROBRAS is renegotiating the contract and the investments will probably be retaken. This measured it seeks to benefit the two countries. In the Brazilian case he intends to diminish the possibility of energy crisis for next years. To Bolivia it is the possibility to sell your principal export input to the largest consuming market of Latin America. (author)

    Full Text Available Uscito a pezzi dalla pesante crisi finanziaria e industriale del 1907, che aveva messo a nudo i limiti della struttura economica del Paese, il capitalismo industriale italiano elaborò un programma, portato avanti fino al primo dopoguerra, che prevedeva l’instaurazione di un governo di tecnocrati. Questo avrebbe dovuto trainare il Paese fuori dalla crisi, pianificarne l’economia e trasformarlo in una grande potenza industriale, con forti connotazioni imperialistiche. Segnali in tale direzione si erano registrati anche nei decenni precedenti, tra fine Ottocento e inizi Novecento, quando ebbe inizio un processo di concentrazione nel settore siderurgico e meccanico. Un percorso peraltro stimolato dalle commesse statali sempre più consistenti (Galli Della Loggia, 1970; Battilossi, 1999; Amatori e Colli, 1999; Bolchini, 2002. La crisi industriale e finanziaria del 1907 e la recessione a livello mondiale che ne seguì, accelerarono la soluzione tecnocratica, che prevedeva un’alleanza, più o meno stretta, con una parte della classe politica e l’entrata in guerra. Negli anni immediatamente seguenti il conflitto, il potere dei tecnocrati sulla scena politica italiana sembrò accrescersi notevolmente, soprattutto quando il governo progettò un programma di espansione economica nelle regioni del Caucaso, nei Balcani e nel Levante ex ottomano, territori in grado di fornire materie prime e di assorbire la produzione italiana in eccesso rispetto alle richieste di un mercato interno asfittico. La collaborazione tra mondo imprenditoriale, bancario e politico non produsse il risultato sperato. La caduta del governo Nitti e il ruolo destabilizzante e filotedesco della Banca Commerciale Italiana nell’Est europeo e nel Caucaso furono tra le cause principali che impedirono il decollo del progetto tecnocratico, provocando una dura reazione da parte dei fratelli Perrone alla guida del gruppo Ansaldo.

Si parte dai riferimenti della letteratura economica sulla teoria dell’informazione per individuare le informazioni economiche rilevanti per monitorare e analizzare il mercato immobiliare, sia dal punto di vista macroeconomico sia da quello microeconomico. In entrambi gli ambiti non è sufficiente soltanto l’informazione sul prezzo, ma su numerose altre variabili. Sull’importanza dell’informazione economica è utile l’indicatore della trasparenza dei mercati immobiliari elaborato da Jones Lang Lasalle costruito anche sulla base di una valutazione sulla qualità e quantità di informazione economica disponibile sugli oggetti scambiati sui fenomeni che caratterizzano il mercato immobiliare.

    Full Text Available The real sector is a strategic component of an economy because it produces and distributes tangible goods and services required to satisfy aggregate demand in the economy. For this reason, there is the need for adequate credit flow from the banking industry to the real sector, which in the Nigerian case, the credit flow has been grossly inadequate. This study is carried out to examine the impact of credit to private sector (CPS on the real sector of Nigeria with a view to assess the significant contribution of CPS to real sector growth in Nigeria. The study used aggregate time series data from 1986 to 2010, which was drawn from central bank of Nigeria (CBN statistical bulletin and CBN annual report and statement of accounts. The data was analysed using multiple regression and based on the coefficient of determination (R square, the study reveals a 96.1% variation between the CPS and real sector growth in Nigeria. The study cocludes that there is a statistically significant impact of credit to private sector on the real sector of Nigeria. This, suggest that the performance of the real sector is greatly influence by credit to private sector. The study recommends that the federal government of Nigeria through the central bank of Nigeria (CBN should enhance the financing of the real sector as well as improve credit flow to the sector because of its strategic importance in creating and generating growth of the economy.

    Antoci, Angelo; Galeotti, Marcello; Iannucci, Gianluca; Russu, Paolo

    2015-01-01

    This paper studies the dynamics of a two-sector economy (with a natural resource-dependent sector and an industrial sector) characterized by free inter-sectoral labor mobility and heterogeneity of agents (workers and entrepreneurs). In such a context, we analyze the effects of the deterioration of natural resources, caused by the production activity of both sectors, on inter-sectoral movements of the labor force (structural changes), on ecological dynamics and on the revenues of workers and entrepreneurs. As in the seminal work by Matsuyama (1992), we obtain that a low productivity of labor in the resource-dependent sector can fuel the industrialization process. However, differently from Matsuyama, in our model the industrialization process may give rise to a reduction in workers’ revenues if the contribution to environmental depletion of the industrial sector, per unit of product, is higher than that of the resource-dependent one.

    One of the main problems for the installation of new natural gas stations has been the high investment for compressor acquisition. Out of 900 thousand Reais, which is an average value for the construction of a supplying structure, 600 thousand are destined for the acquisition of the compression system (average outflow of 800 Nm{sup 3}/hour at 20 deg C, 1 atm), approach commonly used in Brazil. To be economically feasible, it is necessary that the fueling station has a supplying volume of at least 600 vehicles/day. Niches of NGV market have been identified to new potentials, where the compressed gas demand is lower, therefore not justifying an investment in compression systems of high capacity. A solution for reduction of this investment would be the introduction in the Brazilian market of compression systems of medium and low outflow and with lower cost. In this context, CTGAS has a project into RedeGasEnergia in partnership with PETROBRAS, funded by FINEP/CTPETRO, to develop, to acquire, and to mount prototypes of compression systems of small and medium capacities. To attend the objectives of this project, a compressor was developed in a partnership with a national manufacturer, MOVITEC, and participation of CENPES, with an outflow of 200 Nm{sup 3}/hour (at 20 deg C 1 atm.), for a demand of up to 200 vehicles/day. Another alternative, for the case of small consumers with supplying demand of up to 15 vehicles/day is being made possible by the introduction in the Brazilian market of two compression systems of outflow with up to 13,0 Nm{sup 3}/h (at 20 deg C 1 atm). The installation of these systems will assist in the economical and technical feasibility studies. At this moment, there are some companies interested in knowing this new technology for using the compressor in their installations, thus demonstrating the success of this project, as well as the wakening of a new consuming market.

    Full Text Available A conscientização quanto às questões ambientais tem influenciado a decisão de compra e os padrões de consumo que podem indicar a disposição em adquirir um produto com características ecológicas. Este estudo de caso pretende averiguar se investimentos em características ecológicas seriam capazes de trazer retornos financeiros positivos para uma indústria de água mineral de 510 ml. Para tal verificação as análises são feitas com base no modelo proposto por Bertolini (2009, que consistiu em identificar as características ecológicas mais percebidas pelos consumidores, avaliar a disponibilidade em adquirir o produto com tais características, analisar a viabilidade econômica do projeto, além de realizar cruzamentos entre as variáveis. Apurou-se que o fator preço ainda se sobrepõe à conscientização ecológica, e que o consumidor está disposto a pagar o mesmo preço tanto para produto ecológico, quanto para produto convencional. Mesmo diante dessas condições, pode-se dizer que a utilização da ferramenta de análise foi capaz de apontar viabilidade para investimentos em características ecológicas para o produto água mineral de 510 ml.

    This research note analyzes differences in the number of absent working days and doctor visits and in their cyclicality between private sector, public sector and self-employed workers. For this purpose, I used large-scale German survey data for the years 1995 to 2007 to estimate random effects negative binomial (count data) models. The main findings are as follows. (i) Public sector workers have on average more absent working days than private sector and self-employed workers. Self-employed workers have fewer absent working days and doctor visits than dependent employed workers. (ii) The regional unemployment rate is on average negatively correlated with the number of absent working days among private and public sector workers as well as among self-employed men. The correlations between regional unemployment rate and doctor visits are only significantly negative among private sector workers. Copyright © 2012 John Wiley & Sons, Ltd.

    2010-01-01

    Full Text Available El fósforo es un recurso esencial, no renovable y cuyo vertido al medio ambiente provoca graves impactos negativos. Por ello, la recuperación del fósforo contenido en el agua residual se ha convertido en una necesidad para alcanzar el desarrollo sostenible. A pesar de la escasez de este elemento, en la actualidad el precio de venta de las rocas fosfáticas es inferior al del reciclaje del mismo, por lo que no existen incentivos económicos para la implementación de tecnologías de recuperación de este nutriente. En este trabajo se propone una metodología que permite evaluar la viabilidad económica de un proyecto de recuperación del fósforo contenido en las aguas residuales considerando no sólo los impactos internos sino también los externos. Para ello y haciendo uso de la función distancia direccional se estima el precio sombra del fósforo, el cual representa una aproximación a los beneficios ambientales derivados de evitar su vertido al medio ambiente. Así mismo, se realiza una aplicación empírica de esta metodología a una muestra estaciones depuradoras de aguas residuales (EDARs que en la actualidad no cuentan con tratamiento de eliminación ni de recuperación de fósforo. La cuantificación e incorporación del beneficio ambiental en los estudios de viabilidad demuestra que la recuperación del fósforo contenido en las aguas residuales es un proceso viable no sólo desde el punto de vista ambiental sino también desde una perspectiva económica.

    This paper presents a diagnosis of the electrical energy consumption in the library of the Azcapotzalco Unit of the Universidad Autonoma Metropolitana, to determine the actions that can be implemented for energy conservation. This without disturbing the lighting and thermal comfort. The analysis showed that, by changing the reflecting surfaces of the lighting lamps, the number of units can be reduced, without lowering the illumination level below the recommended values. The saving was estimated for replacement of the fluorescent lamps for others of metallic halogenides in the areas where the ceiling is high; for the installation of switches to improve the selectivity in turning on and turning off the lamps, achieving this way a better usage of the natural light; for the reduction of the electric load of the air conditioning units which will be obtained in incorporating induced draft shafts; and for an improvement in the electric and ballast installation. For the actions that turned out to be redeemable in three years the assistance of the Fideicomiso de Apoyo al Programa de Ahorro de Energia del Sector Electrico (FIDE) of the Comision Federal de Electricidad (CFE) has been available.

O Valor Presente Líquido (VPL, a Taxa Interna de Retorno (TIR, o Valor Esperado da Terra (VET e o Valor Anual Equivalente (VAE foram os indicadores utilizados na avaliação financeira, a uma taxa de desconto de 10% ao ano. Os resultados deste trabalho indicaram que, com esta taxa, os projetos de eucalipto e pinus foram viáveis sem os recursos adicionais dos CERs (Certificados de Emissões Reduzidas, ressaltando-se que a inclusão dos créditos de carbono propiciou aumento da viabilidade financeira destes. Já o projeto da heveicultura mostrou-se viável apenas com os Certificados de Carbono. A receita advinda da venda dos CERs aumentou consideravelmente a viabilidade financeira dos três projetos, mesmo considerando a tonelada de CO2 a US$3,00. Caso o Protocolo de Kyoto seja ratificado, haverá um incremento no preço pago pela tonelada de CO2, que ocasionará o aumento da contribuição dos CERs em projetos florestais.The objective of the present work was to study the influence of carbon credits on the financial viability of three forest projects.

Temperatura e teor de umidade estão entre os fatores que mais afetam sua longevidade. O objetivo deste trabalho é o estudo da viabilidade e dormência de uva do cultivar Patrícia, armazenada durante 24 meses em dois tipos de recipientes - em vidro hermético e saco de papel - a temperaturas de 10, 20 e 30°C, com dois diferentes teores iniciais de umidade. A porcentagem de sementes dormentes e viáveis foi determinada bimestralmente durante os primeiros 12 meses, e semestralmente nos períodos mais longos. O armazenamento não quebrou a dormência das sementes de uva em nenhuma das condições estudadas. Enquanto as sementes frescas mostraram melhor conservação a 10°C quando embaladas em vidro hermético, sementes secas se conservaram melhor a 20°C. Em saco de papel, foram poucas as diferenças encontradas entre os tratamentos, a não ser nos períodos finais do armazenamento, quando 20°C se mostrou a pior temperatura de conservação. Dessa maneira, a dormência não foi alterada pelo armazenamento, nas condições estudadas, e a viabilidade foi bastante afetada tanto pelo tipo de embalagem como pela temperatura de armazenamento.Longevity of seeds is affected by the storage conditions, being temperature and seed moisture content the major factors to keep seeds viable.

    Full Text Available Esta pesquisa teve como finalidade estudar a viabilidade do preparo direto para descanso em cíngulo de incisivo central superior, por intermédio de processamento de imagem. Foram reproduzidos dez dentes íntegros, montados em um suporte de alumínio com resina acrílica e distribuídos entre cinco especialistas, que executaram os preparos para descanso. Em seguida, os corpos-de-prova foram cortados ao longo de suas coroas, tendo como guia um corte inicial, feito no centro da borda incisal de cada dente. O preparo foi então dimensionado, estabelecendo-se medidas lineares e angulares que permitissem uma análise comparativa entre o perfil original do dente e aquele após o preparo, enquanto se determinava a perfuração ou não da camada de esmalte. Todas as observações foram feitas, digitalizando-se os perfis e processando as imagens num programa específico. Dos cinqüenta modelos preparados, seguindo critérios estabelecidos, trinta e três perfuraram a camada de esmalte.

    Full Text Available Proporcionalmente ao crescimento do consumo de energia, cresceu a poluição, fazendo-se necessário o desenvolvimento de fontes energéticas “limpas”, que permitam a estabilização desse quadro de poluição. Por esse motivo as pesquisas têm se concentrado no desenvolvimento de novos insumos básicos, de caráter renovável, para a produção de combustíveis que possam substituir os derivados de petróleo, o que coloca a biomassa em papel de destaque. Nesse sentido a incorporação do biodiesel à matriz energética constitui um ganho ambiental significativo devido à redução das emissões. Sendo as microalgas produtores primários que armazenam energia solar para convertêla em energia biológica, o pressente trabalho busca uma análise de seu uso para a produção de biodiesel. Para este fim se propõe discutir a sua viabilidade técnica, econômica e ambiental levando em conta alguns cenários prováveis. Sem dúvidas as alternativas mais promissórias serão aquelas que apliquem o conceito de biorefinaria para otimizar a economia do processo assim como os ganhos ambientais.

    Full Text Available The study seeks to assess the structure of the economy of Ghana in terms of changes in the economic structure before and after the production of oil in commercial quantities. This is viewed with regards to economic multipliers, sectoral interdependence and trade concentration. The results show that changes occurred with regards to multipliers and sectoral interdependence. The output multipliers of most sectors have declined. The results also show that the agricultural sector experienced an initial decline in its growth while industry experienced an increase. The performance of the services sector was relatively stable for the period covered by the study. There is a decline in the level of trade concentration though on a whole the concentration index is still high. The study employed input-output modeling techniques and the data was obtained from the Ghana statistical service and the World Development Indicators.

    Os sistemas silvipastoris (SSPs consistem de um conjunto de metodologias que podem ser consideradas promissoras para recuperar áreas de pastagens degradadas da Amazônia, por integrar o cultivo arbóreo ao pecuária tradicional. Embora já utilizados em pequena escala por produtores inovadores, os SSPs carecem de uma base científica que forneça subsídios técnicos ao seu uso mais amplo, sobretudo quando se trata de justificar a viabilidade econômica desses sistemas. O objetivo desse estudo foi analisar a viabilidade econômica de SSPs utilizados por produtores no nordeste do Estado do Pará, comparando-os ao monocultivo tradicional. Os sistemas são compostos basicamente pelo paricá (Schizolobium parahyba var. amazonicum (Huber ex Ducke Barneby ou teca (Tectona grandis L.F., em pastagens de quicuio-da-amazônia (Brachiaria humidicola (Rendle Schweick pastejados por bovinos. A análise de viabilidade econômica foi realizada por meio dos métodos: valor presente líquido (VPL, taxa interna de retorno (TIR e relação benefício/custo (Rb/c, considerando quatro SSPs e o monocultivo de paricá e teca. Os sistemas compostos por teca apresentam maior atratividade econômica do que os com paricá, e dentre eles, os arranjos silvipastoris, em que o gado era próprio, foram considerados de melhor viabilidade que os sistemas em monocultivo ou em que a incorporação animal se dava através do aluguel da pastagem.

Las mujeres en España presentan tasas de desempleo, trabajo temporal y a tiempo parcial mucho mayores que los hombres. Además, las condiciones de acceso al mercado de trabajo y las condiciones en las que éste se desempeña están también muy relacionadas con la clase social. Las mujeres cubren la escasez de servicios públicos destinados al cuidado de las criaturas pequeñas y de las personas mayores o dependientes, y realizan una labor de cuidadoras informales sin reconocimiento social, lo cual les impide el acceso a un puesto de trabajo o su mantenimiento y limita de forma decisiva las posibilidades de desarrollo y progreso profesional. Todo ello indica una clara diferencia con respecto a los hombres en cuanto a la frecuencia de contratos temporales y de tiempo parcial, así como en la segregación laboral, tanto horizontal como vertical. Estos aspectos de segregación son más evidentes en las mujeres de clases sociales menos privilegiadas, en las que se concentran las peores condiciones de acceso al mercado laboral y de trabajo. En España es imprescindible llevar a cabo políticas que ofrezcan servicios que permitan compatibilizar la vida laboral y familiar en condiciones de mayor equidad, tanto en razón de género como de clase social.In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones.

    Injury to children in Europe, resulting in both death and disability, constitutes a significant burden on individuals, families and society. Inequalities between high and low-income countries are growing. The World Health Organisation Health 2020 strategy calls for inter-sectoral collaboration to address injury in Europe and advocates the whole of government and whole of society approaches to wicked problems. In this study we explore which sectors (e.g. health, transport, education) are relevant for four domains of child safety (intentional injury, water, road and home safety). We used the organigraph methodology, originally developed to demonstrate how organizations work, to describe the governance of child safety interventions. Members of the European Child Safety Alliance, working in the field of child safety in 24 European countries, drew organigraphs of evidence-based interventions. They included the different actors involved and the processes between them. We analyzed the organigraphs by counting the actors presented and categorizing them into sectors using a pre-defined analysis framework. We received 44 organigraphs from participants in 24 countries. Twenty-seven sectors were identified across the four domains. Nine of the 27 identified sectors were classified as 'core sectors' (education, health, home affairs, justice, media, recreation, research, social/welfare services and consumers). This study reveals the multi-sectoral nature of child safety in practice. It provides information for stakeholders working in child safety to help them implement inter-sectoral child safety interventions taking a whole-of-government and whole-of-society approach to health governance. © The Author 2017.

    Full Text Available Resumo O mundo está vivenciando uma profunda mudança climática, causada pela atividade predatória do homem, tendo em vista que as atividades econômicas foram exercidas sem preocupação com os impactos causados ao meio ambiente. Entretanto, na atualidade, percebe-se a necessidade de se expandir a economia atual sem comprometer os recursos necessários para a sobrevivência das futuras gerações. O uso intensivo de fontes alternativas de energia se configura uma contribuição a essa nova perspectiva de desenvolvimento. Em outra vertente, as principais técnicas de análise de viabilidade econômico-financeira são amplamente conhecidas, entretanto, a aplicação de técnicas que considerem o risco não é tão trivial. Assim, o presente trabalho aborda a seguinte questão: é possível analisar a viabilidade econômico-financeira de um potencial parque de geração de energia eólica em diferentes localidades do Brasil considerando o risco por meio das técnicas auxiliares de simulação de Monte Carlo e a distribuição Beta? Para responder tal questionamento, foram realizados testes considerando quatro diferentes localidades no Brasil, aplicando o método da Taxa Interna de Retorno (TIR aliado às mencionadas técnicas auxiliares a fim de considerar o risco na análise de investimentos. Os resultados demonstraram a sensibilidade do projeto eólico à necessidade de financiamento para todas as regiões estudadas.

  1. Torus sector handling system

    International Nuclear Information System (INIS)

    Grisham, D.L.

    1981-01-01

    A remote handling system is proposed for moving a torus sector of the accelerator from under the cryostat to a point where it can be handled by a crane and for the reverse process for a new sector. Equipment recommendations are presented, as well as possible alignment schemes. Some general comments about future remote-handling methods and the present capabilities of existing systems will also be included. The specific task to be addressed is the removal and replacement of a 425 to 450 ton torus sector. This requires a horizontal movement of approx. 10 m from a normal operating position to a point where its further transport can be accomplished by more conventional means (crane or floor transporter). The same horizontal movement is required for reinstallation, but a positional tolerance of 2 cm is required to allow reasonable fit-up for the vacuum seal from the radial frames to the torus sector. Since the sectors are not only heavy but rather tall and narrow, the transport system must provide a safe, stable, and repeatable method fo sector movement. This limited study indicates that the LAMPF-based method of transporting torus sectors offers a proven method of moving heavy items. In addition, the present state of the art in remote equipment is adequate for FED maintenance

    This paper examines whether sectoral backward and forward linkages can generate positive externalises in sectoral innovation through diffusion of technological knowledge, both across countries within a sector or across sectors within a country. Using a sample of 14 OECD countries and 12 sectors over the period 1995-2005 we find that forward linkages enhance sectoral innovation. Intra sectoral slipovers are important among sectors and countries with low-to-medium R an D intensity while inter sectoral slipovers have a major impact on sectors with high R and D intensity.

  4. INTRODUCTION OF A SECTORAL APPROACH TO TRANSPORT SECTOR FOR POST-2012 CLIMATE REGIME

    2009-01-01

    Full Text Available Recently, the concept of sectoral approaches has been discussed actively under the UNFCCC framework as it could realize GHG mitigations for the Kyoto Protocol and beyond. However, most studies have never introduced this approach to the transport sector explicitly or analyzed its impacts quantitatively. In this paper, we introduce a sectoral approach which aims to set sector-specific emission reduction targets for the transport sector for the post-2012 climate regime. We suppose that developed countries will commit to the sectoral reduction target and key developing countries such as China and India will have the sectoral no-lose targets — no penalties for the failure to meet targets but the right to sell exceeding reductions — for the medium term commitment, i.e. 2013–2020. Six scenarios of total CO2 emission reduction target in the transport sector in 2020, varying from 5% to 30% reductions from the 2005 level are established. The paper preliminarily analyzes shares of emission reductions and abatement costs to meet the targets for key developed countries including the USA, EU-15, Russia, Japan and Canada. To analyze the impacts of the proposed approach, we generate sectoral marginal abatement cost (MAC curves by region through extending a top-down economic model, namely the AIM/CGE model. The total emission reduction targets are analyzed against the developed MAC curves for the transport sector in order to obtain an equal marginal abatement cost which derives optimal emission reduction for each country and minimizes total abatement cost. The results indicate that the USA will play a crucial role in GHG mitigations in the transport sector as it is most responsible for emission reductions (i.e. accounts for more than 70% while Japan will least reduce (i.e. accounts for about 3% for all scenarios. In the case of a 5% reduction, the total abatement is equal to 171.1 MtCO2 with a total cost of 1.61 billion USD; and in the case of a 30

Ten genotypes of annual ryegrass (L. multiflorum were evaluated for the viability of pollen grains using propionic carmine and Alexander's stains, while morphology was assessed by the acetolysis technique. Measures of polar axis (P, equatorial diameter (E, exine thickness, and analysis of pollen grains were obtained by scanning electron microscopy (SEM. All genotypes showed high rate of pollen viability (> 89% for both stains. There were differences between genotypes in the following quantitative traits: polar axis, equatorial diameter, exine, endexine, ektexine, and P/E ratio. Pollen grains were characterized as small, monoporates, with circular and non-prominent apertures. In addition to helping distinction of pollen grains, morphometric differences can be used later to compare ploidy levels, thus assisting in breeding programs of the species.O estudo e a caracterização do grão de pólen são fundamentais para diferentes áreas, em especial, para a taxonomia, o melhoramento genético, a filogenia e a paleobotânica. Para genótipos de Lolium multiflorum Lam., naturalizados no Brasil, cultivares introduzidas ou populações de melhoramento, diploides e poliploides, não existem relatos sobre a caracterização morfopolínica. Nesse trabalho foram analisados dez gentótipos de azevém anual (L. multiflorum. A viabilidade dos grãos de pólen foi verificada por coloração com os corantes carmim propiônico e Alexander e a morfologia por meio da técnica de acetólise, sendo obtidas medidas do eixo polar (P, do diâmetro equatorial (E, e da espessura da exina, e análise dos grãos de pólen por microscopia eletrônica de

    During this time Siak regency only known as oil producing regency in Riau province, but based on the vision of spatial planning Siak’s regency in 2031 there was a shift from petroleum towards to other sectors such as agribusiness, agroindustry and tourism. The purpose of this study was to identify the sector base, the leading subsectors and shift with their characteristics and to identify the leading subsectors development priority. The method used in this research consisted of the method of Location Quotient (LQ, Shift Share, and Overlay method). The research results were used Location Quotient (LQ) to identify sector’s base in Siak regency based on the document of PDRB. The sector’s refers to the constant prices year of 2000 were mining and quarrying sector (2.25). The sector’s base using document of PDRB at constant prices 2000 without oil and gas sector was the agricultural sector with a value of LQ was 2,45. The leading sub sector in the Siak regency with mining and quarrying sector was oil and gas (1.02) and leading sub sector without oil and gas sector was the plantation sector (1.48) and forestry sector (1.73). Overlay analysis results shown that agriculture sector as a sector base and plantation and forestry as a leading sub sector has positive value and categorize as progressive and competitiveness. Because of that, this leading sub sector gets high priority to developing.

    Full Text Available PURPOSE: To evaluate the effects of capsaicin on the viability of ischemic random-pattern skin flaps in rats. METHODS:Forty EPM1-Wistar rats were randomized into two groups of 20 animals each, the capsaicin group and the control group. A random-pattern skin flap measuring 10 x 4cm was raised and a plastic barrier was placed between the flap and the donor site. After the surgical procedure, the control group was treated with an inert vehicle in the form of a cream applied uniformly to a rayon bandage which, in turn, was applied to the surface of the skin flap. The capsaicin group was treated in the same way, but in this case capsaicin was added to the cream. This procedure was repeated for two consecutive days. RESULTS: There was a significantly smaller amount of flap necrosis in the capsaicin group (35.07% than in the control group (44.75% (p=0.035. CONCLUSION:Topical administration of capsaicin improved the viability of ischemic random-pattern skin flaps in rats.OBJETIVO: Avaliar os efeitos da capsaicina na viabilidade de retalhos isquêmicos randômicos em ratos.

    believe that structural change is an unimportant side effect of the economic development. On the contrary, economists associated with the World Bank and some others posit that growth is brought about by the changes in sectoral composition. The objective of this study is to empirically test...... the relationship between sectoral shares and economic growth by using the panel data for 20 developed countries. The results of the granger causality suggest that both services and agriculture sectors do granger cause economic growth, whereas industrial sector does not granger cause growth. Reverse causality does...... not hold for any of the three sectors. The results of Barro and Non-Barro regressions along with the set of control variables have suggested that services sector is negatively affecting growth, whereas both industrial and agriculture shares are positively affect economic growth....

    Full Text Available O agronegócio possui características peculiares que dificultam a produção e aumentam os riscos, necessitando de uma postura profissional por parte do empresário rural. A produção de hortaliças em ambiente protegido utilizando-se das técnicas da hidroponia apresenta-se como alternativa para o produtor numa economia competitiva e globalizada, uma vez que permite a redução de perdas e o aumento da produtividade de diversas culturas. Avaliou-se no presente trabalho a viabilidade econômica da produção de alface crespa em sistema hidropônico. Os dados de custo de produção foram obtidos entre abril de 2007 e maio de 2007 em Lavras MG. Concluiu-se que a atividade encontra-se numa situação de resíduo negativo com cobertura dos recursos variáveis e parte do custo fixo, ou seja, a tendência do hidroponicultor a médio e longo prazo é de retrair e sair da atividade, pois a atividade encontra-se em processo de descapitalização. O produtor necessitaria de encontrar meios para elevar a sua produção mensal a fim de atingir o ponto de nivelamento, igualando sua receita total com seu custo total.

    Full Text Available A C. albicans é um fungo comensal e oportunista, que em casos de imunossupressão pode causar infecções e levar o indivíduo à morte. O biofilme produzido por C. albicans apresenta resistência a vários antifúngicos, pois é formado por uma matriz extracelular que dificulta a difusão dos fármacos. A Terapia Fotodinâmica Antimicrobiana (TFA é uma terapia que combina uma fonte de luz visível, um agente fotossensível (não tóxico e oxigênio. Esta interação promove a produção de espécies reativas de oxigênio (ERO’s, que alteram a permeabilidade da membrana celular e podem levar à morte celular de microrganismos. Foi realizada a TFA em biofilmes produzidos por C. albicans em diferentes fases de desenvolvimento. A fonte de luz utilizada foi um Light Emitting Diode (LED (630nm e o agente fotossenssível utilizado foi o Azul de Toluidina (AT. Os resultados demonstraram que tanto sobre a formação quanto sobre o biofilme produzido por C. albicans a TFA foi capaz de reduzir a viabilidade celular e alterar a morfologia, diminuindo a quantidade do número de células e de filamentos. Assim, a TFA demonstra ser uma potencial terapia antifúngica.

Avaliaram-se a frutificação efetiva em ramos ensacados e não ensacados, e aspectos da morfologia floral. A viabilidade de pólen foi avaliada em meio de cultura com e sem ácido bórico, com pólen coletado em diferentes períodos após antese. A germinação de pólen de seis genótipos foi quantificada antes e após armazenamento. P. trunciflora e P. jaboticaba são autocompatíveis, porém os polinizadores aumentam a frutificação. A espécie Plinia cauliflora necessita de agentes polinizadores para frutificar, pois apresenta flores com maior distância estigma-anteras que as outras duas espécies, o que impede a autofecundação passiva. A adição de ácido bórico no meio de cultura aumenta a germinação in vitro de pólen de jabuticabeira. A viabilidade do pólen é máxima após seis horas da antese. É possível a conservação do pólen por até 90 dias em congelador (-18ºC, desde que apresente alta germinação inicial (maior que 80%.

    Through a detailed analysis of market determining factors, of evolutions of supply and demand, and of major events in firms life, this set of two reports proposes an analysis of the recent situation of the gas sector and of the evolutions of the competitive game. The first report on situation and predictions which is updated three times a year, proposes a synthesis on the consequences of the evolution of the economic environment, on major trends noticed for the sector, and on predictable evolutions. It proposes the most recent predictions regarding natural gas consumption in France and the turnover of the gas sector. It highlights recent events for companies of the sector: takeovers, investments, restructuring, introduction of new products, and so on. It proposes a sector-based dashboard which contains all the critical figures useful to analyse the sector situation (activity determining factors, key figures for the sector and its environment). The second report (the annual one) proposes an overview of trends and competition within the gas sector. It gives an overview of some basic aspects of the activity (sector organisation, gas categories, main customer markets, gas consumption in industry), and of its determining factors, analyses the sector environment (sites connected to the natural gas network, evolution of average temperatures in France, production by chemical industry, by the food industry, and by metallurgy and oil refining, thermal production of electricity, regulatory evolution regarding supports to energy efficiency, and new opportunities). The evolution of the sector activity is analysed through its trends and indicators (turnovers, gas consumption, butane-propane deliveries, wholesale prices, regulated tariffs). The economic structure is also analysed: aspects related to the upstream part (extraction, injection of biogas, natural gas main input and output points, transport and storage, natural gas distribution), and aspects related to gas provision

Nonetheless, many economists are convinced that such changes are important only in pushing up the rate of economic development, which in the long run would otherwise be lower and constant, with capital accumulation and labor force growth taking place gradually. To the contrary, the present work argues that in the long run, technical progress is not the main factor of economic development, but rather a necessary condition. The author examines technological change in economic theory and the history of economic development. Technological unemployment and Keynesian unemployment are then considered as well as the reduction of working hours.

    Purpose The purpose of this paper is to expand attention to responsible leader behavior in the world's health sectors by explaining how this concept applies to health sectors, considering why health sector leaders should behave responsibly, reviewing how they can do so, and asserting potential impact through an applied example. Design/methodology/approach This paper is a viewpoint, reflecting conceptualizations rooted in leadership literature which are then specifically applied to health sectors. A definition of responsible leader behavior is affirmed and applied specifically in health sectors. Conceptualizations and viewpoints about practice of responsible leader behavior in health sectors and potential consequences are then discussed and asserted. Findings Leadership failures and debacles found in health, but more so in other sectors, have led leadership researchers to offer insights, many of them empirical, into the challenges of leadership especially by more clearly delineating responsible leader behavior. Practical implications Much of what has been learned in the research about responsible leader behavior offers pathways for health sector leaders to more fully practice responsible leadership. Social implications This paper asserts and provides a supporting example that greater levels of responsible leader behavior in health sectors hold potentially important societal benefits. Originality/value This paper is the first to apply emerging conceptualizations and early empirical findings about responsible leader behavior specifically to leaders in health sectors.

    Morrissey, David E.; Poland, David; Zurek, Kathryn M.

    2009-01-01

    We discuss mechanisms for naturally generating GeV-scale hidden sectors in the context of weak-scale supersymmetry. Such low mass scales can arise when hidden sectors are more weakly coupled to supersymmetry breaking than the visible sector, as happens when supersymmetry breaking is communicated to the visible sector by gauge interactions under which the hidden sector is uncharged, or if the hidden sector is sequestered from gravity-mediated supersymmetry breaking. We study these mechanisms in detail in the context of gauge and gaugino mediation, and present specific models of Abelian GeV-scale hidden sectors. In particular, we discuss kinetic mixing of a U(1) x gauge force with hypercharge, singlets or bi-fundamentals which couple to both sectors, and additional loop effects. Finally, we investigate the possible relevance of such sectors for dark matter phenomenology, as well as for low- and high-energy collider searches.

    Projects with large infrastructures, particularly those in the field of energy, provide a strong boost to certain industrial sectors in the country. In the case of Spain, the policy of direct management 'by components' of these projects - hydroelectric power plants, petrochemical plants, thermoelectric plants and nuclear power plants - adopted by the electric utility owners has furthered not only the local equipment manufacturing industry but also the engineering sector. At present, with full implementation of the Single Market in sight, it is particularly interesting for Spain to continue building up a powerful engineering sector, increasing its size and usefulness, and extending its traditional areas of action to other technologies, more on the lines of engineering and consulting firms in the USA than in the rest of Europe. The intention is to endow our equipment and construction companies with the skills necessary to enable them to compete with large European conglomerates in their respective sectors. The structure of these conglomerates usually contains engineering capabilities which are not habitual in our industry. Examples are given, showing how this model has been used to compete and win awards for important international projects. A specific analysis has been made of the position of Spanish engineering and industry in nuclear power generation projects in the former Soviet Union and East European countries, in which large investments are expected to be made.

    The energy sector is a key driver of the economic pillar of Vision 2030. As the economy grows, urbanization intensifies and incomes increase, corporate and household demand for energy also rises. To meet this growth in demand for energy, the sector needs to increase investments and diversify into more sources of energy such as geothermal and wind power. It is therefore critical that focus is directed towards development and sustainability of the energy sector to ensure delivery of least cost power that will improve Kenya's competitiveness and achieve the Vision 2030 objective of 10% average annual economic growth.

    Full Text Available The Cole Royal Commission enquiry into the building and construction (abbreviated to ‘construction’ sector recommended controversial workplace-relation reforms for that sector. The recommended changes are likely to be enshrined in legislation within the year. The Commission drew on analyses of industrial disputes that focused, in the main, on quite recent experience. This paper attempts to give a broader historical perspective on disputes in that sector by considering the pattern of disputes for the entire post-World War II period. Accordingly, data on disputes and employees during the entire period are gathered from Australian Bureau of Statistics current and archived sources. These data are classified according to sector (construction versus non-construction and analysed. It is found that the strike rate has, on average, been greater in the construction sector than in the non-construction sector. However, there have been periods during which disputes in the construction sector have been relatively low. The most recent period was during the period of the Accord (1983-96, during which the strike rate in the construction sector fell relatively strongly. The analysis of this relatively broad historical period draws attention, among other things, to the possibility that the sort of strategies employed during the Accord years – strategies of cooperation and consensus building – may provide a more effective means of bringing industrial peace to the workplace relations scene of the construction sector than policies that are relatively confrontational.

    Economists consider a well-functioning financial sector to be of first order importance for a modern (capitalist) economy. However, in the aftermath of the financial crisis a debate about the future role of the financial sector emerged and many commentators have called into question whether...... the financial sector actually creates value for the wider society. This research, which is part of a broad research project “Nordic Finance and the Good Society”, aims to contribute to this debate by studying the role of the financial sector structure for economic development of an economy. Therefore......, it proceeds in five steps. First, it provides some reflections on the financial sector and the existing literature studying financial sector structure and its association with economic development. Second, it presents stylized firm-level evidence on capital structure choice and firm behavior. It is argued...

    The energy sector in Italy, as in Europe and in many other areas of the world, is undergoing rapid and profound changes. The 1986 ratification of the European Single Act was intended to create a European internal market, where circulation of people, capital, goods, and services would reach the highest possible liberalization. In 1988, in the document The Energy Internal Market, the European Union (EU) commission stressed the need for creation of an internal energy market--free of obstacles--to increase security of supply, to reduce costs, and to strengthen the competitiveness of the European economic system. In 1990, the Community Council adopted directives to implement the EU energy sector. This article describes Italy's role as part of the EU energy sector. It covers the following topics: the Italian energy sector; electricity vs gas transportation; project finance; recent developments advance Italian power industry; specifying powerplant components -- Italian stype; buyers' guide to Italian equipment, services

    This paper presents the arguments in favor of government intervention in financing and regulation of health in Brazil. It describes the organizational arrangement of the Brazilian health system, for the purpose of reflection on the austerity agenda proposed for the country. Based on the literature in health economics, it discusses the hypothesis that the health sector in Brazil functions under the dominance of the private sector. The categories employed for analysis are those of the national health spending figures. An international comparison of indicators of health expenses shows that Brazilian public spending is a low proportion of total spending on Brazilian health. Expenditure on individuals' health by out-of-pocket payments is high, and this works against equitability. The private health services sector plays a crucial role in provision, and financing. Contrary to the belief put forward by the austerity agenda, public expenditure cannot be constrained because the government has failed in adequate provision of services to the poor. This paper argues that, since the Constitution did not veto activity by the private sector segment of the market, those interests that have the greatest capacity to vocalize have been successful in imposing their preferences in the configuration of the sector.

    In September 2005, AFD's Research Department launched a Research Program on Public Private Partnerships with an approach combining economic analysis (contractual incentives, financing of investment, etc.) with a sociological and political approach to regulatory issues. Various case studies have been conducted in different sectors (water and sanitation, power, transport) and countries. This study falls within the above research framework since India - like most major developing countries - has attempted to introduce market forces in its electric power systems. At the same time, growing concern over global climate change has put the spotlight on the need for India to control its emissions of greenhouse gases (GHG). India is currently the world's sixth biggest producer of GHG emissions, but is the second biggest if one considers the rate of augmentation of its emissions. Half of India's total GHG emissions are produced by its power sector, and 70 per cent of electricity is generated by thermal power plants, mainly from coal. Climate change mitigation in the power sector is thus a strategic issue for AFD in India. This study is structured so as to examine the intersection of these two crucial challenges in India by exploring the links between private participation in the power sector in India and the reduction of GHG emissions

Asimismo se trató de establecer si ambos procedimientos determinan la viabilidad de las mismas especies o si existen diferencias en las especies establecidas como viables. El número de semillas viables estimado por la técnica VPP fue de 3475 (9,85% del total del banco de semillas, en tanto el número de semillas no viables fue de 31795 (90,15% del total del banco de semillas. Luego de aplicar la técnica de germinación (5 ciclos sobre ambas categorías, en las viables se obtuvo una germinación de 3286 semillas (9,32% del total del banco de semillas, no germinando 189 semillas (0,53% del total de dicho banco. Hubo un 7.23% adicional del banco de semillas que resultó viable por germinación, cuando previamente había sido considerado no viable por la técnica VPP. Los resultados alcanzados muestran que la técnica VPP realiza una subestimación significativa del banco de semillas, en tanto la sobreestimación no alcanzó niveles de significancia. Estos resultados ponen de manifiesto que con la técnica VPP no sólo se obtiene un menor número total de semillas viables, sino que no permitiría reflejar la verdadera proporción de semillas viables y no viables del banco total. Cuando se incorpora al análisis la técnica de germinación, se encuentra que la proporción del banco no es la misma de acuerdo a la metodología empleada, pues mientras la VPP establece, dentro del banco, semillas viables y no viables, se observó que aplicando la técnica de germinación algunas semillas consideradas viables no germinaron mientras que otras consideradas como no viables sí lo hiciero.The objective of this study was to compare the viability of seeds obtained through the techniques "viability by pressure" (VBP and "viability by pressure plus

    Full Text Available Abstract Background Recruiting and retaining health professions remains a high priority for health system planners. Different employment sectors may vary in their appeal to providers. We used the concepts of inflow and stickiness to assess the relative attractiveness of sectors for physical therapists (PTs in Ontario, Canada. Inflow was defined as the percentage of PTs working in a sector who were not there the previous year. Stickiness was defined as the transition probability that a physical therapist will remain in a given employment sector year-to-year. Methods A longitudinal dataset of registered PTs in Ontario (1999-2007 was created, and primary employment sector was categorized as ‘hospital’, ‘community’, ‘long term care’ (LTC or ‘other.’ Inflow and stickiness values were then calculated for each sector, and trends were analyzed. Results There were 5003 PTs in 1999, which grew to 6064 by 2007, representing a 21.2% absolute growth. Inflow grew across all sectors, but the LTC sector had the highest inflow of 32.0%. PTs practicing in hospitals had the highest stickiness, with 87.4% of those who worked in this sector remaining year-to-year. The community and other employment sectors had stickiness values of 78.2% and 86.8% respectively, while the LTC sector had the lowest stickiness of 73.4%. Conclusion Among all employment sectors, LTC had highest inflow but lowest stickiness. Given expected increases in demand for services, understanding provider transitional probabilities and employment preferences may provide a useful policy and planning tool in developing a sustainable health human resource base across all employment sectors.

  19. Private Sector Credit and Inflation Volatility

    Directory of Open Access Journals (Sweden)

    Lorna Katusiime

    2018-04-01

    Full Text Available This paper investigates the effect of inflation volatility on private sector credit growth. The results indicate that private sector credit growth is positively linked to the one period lagged inflation volatility. Given that past monetary policy actions continue to affect the targeted variables due to the substantial lags in the transmission mechanism, the positive response of private sector credit growth to past inflation volatility suggests a credible monetary policy regime in Uganda, which has led to a reduction in the level of macroeconomic uncertainty and the restoration of favorable economic conditions and prospects, thus increasing the demand for credit. Further, the study finds that the lagged private sector credit growth, nominal exchange rate, and inflation have a statistically significant effect on private sector credit growth while financial innovation, interest rates, and GDP growth appear not to be important determinants of private sector credit growth. The robustness of our findings is confirmed by sensitivity checks.

  20. Smart grids and the transformation of the electricity sector: ICT firms as potential catalysts for sectoral change

    Erlinghagen, Sabine; Markard, Jochen

    2012-01-01

    The sustainability challenges associated with increasing demand and generation of electricity require a far-reaching transformation of the energy system. Smart grid technologies are expected to play a major role in such sectoral transformation. While a growing body of literature is concerned with the dynamics and particularities of sectoral transformation, most contributions have focused on exogenous shocks or new technological developments as drivers of change. This paper complements the existing perspectives by exploring the role of actors as catalysts for transformation. Within the field of smart grid, we study the transformative influence of ICT firms on the energy sector in Europe. More specifically, we analyze actor participation in 450 European smart grid projects between 2000 and 2011 as well as acquisitions in the field. We find that incumbent firms from the ICT sector have gained influence and drive transformation through the creation of variety, in terms of technology, business models and value chains. As a strategic reaction, electricity sector incumbents have recently acquired many start-ups specialized in ICT technology and thus expanded their competence base. We conclude that entrants from another sector can be important catalysts for sectoral transformation and should be analyzed more systematically in transition studies. - Highlight: ► Entrants from adjacent sectors are important catalysts for sectoral transformation. ► We provide a socio-technical systems perspective on smart grid. ► We analyze actor participation in smart grid projects in Europe 2000–2011. ► ICT firms drive transformation towards a smarter grid.

  1. Account for sector heterogeneity in China's energy consumption. Sector price indices vs. GDP deflator

    International Nuclear Information System (INIS)

    2010-01-01

    A common practice in decomposition analyses is to deflate output indicators to purge the impact of inflation by using a general deflator. This practice fails to account for sector heterogeneity and can be hazardous. Although the general identified patterns are largely correct, the calculated magnitudes can be misleading or even wrongly signed. Instead, it is strongly recommended that sector heterogeneity is accounted for by using individual sector price indices for all relevant sectors instead of one general (GDP) deflator. This paper analyzes this advanced decomposition using Chinese data and compares to the usual method of using only one deflator. It is found that while most differences are only of quantitative quality, some show even a qualitative difference. Furthermore, the rising energy intensity in the early 2000s, which has been discussed by previous studies, vanishes completely. (author)

    Reflections on science and the communication sector. In this contribution I will reflect about successes and failures in communicating climate change and air pollution sciences to the general public. These communication efforts included writing popular articles, giving public presentations, working with people from the social scientists and artists. Giving the fact that communication is a very important (economic) sector on its own, the question is to what extent scientists should enter that sector, whether scientists are at all accepted in that sector, whether they should use the expertise in that sector, or whether they should merely provide the knowledge to be used by that sector.

Para ello se utilizaron tres suspensiones de larvas de T. spiralis (M1, M2 y M3, las que fueron expuestas a diferentes condiciones y observadas a distintos tiempos: M1 se expuso a -30 °C y se observó a los 70 días; M2 a 80 °C durante 5 minutos y se observó inmediatamente, y M3 se mantuvo a 4 °C durante todo el experimento, como testigo del 100% de vitalidad. Cada suspensión contenía 500 estadios larvarios libres. Se emplearon 100 μl de solución de azul de metileno 1:10 000 en agua destilada, agregados a igual volumen de suspensión de larvas, y las muestras fueron observadas al microscopio óptico para evaluar la motilidad. Los resultados evidenciaron que cuando las larvas de T. spiralis estaban muertas (M1 y M2, el 100% se coloreaban totalmente de azul en su interior, y las estructuras internas, en relación con la capa quitinosa, aparecían retraídas y algunas fragmentadas. En la suspensión testigo M3 las larvas no se coloreaban, y como prueba adicional de viabilidad se pudo observar su típico movimiento en espiral en el 100% de ellas.The present research was carried out with the purpose of determining whether or not the methylene blue test could also evidence viability of free larvae of Trichinella spiralis, taking into account its usefulness in the determination of viability of protoscolices in Echinococcus granulosus.

    Full Text Available Se ha realizado un análisis hidroquimico de 18 pozos ubicados en la zona periurbana oeste de la ciudad de Cochabamba. También se ha efectuado una evaluación de la viabilidad técnica de diferentes procesos de remoción de arsénico en función de los parámetros físicos y químicos de calidad de las aguas provenientes de los pozos más contaminados. Se han logrado los siguientes resultados importantes: La tendencia de evolución geoquímica hacia el tipo de agua Na-Ca-HCO3 puede ser causada por la mineralización y/o disolución de minerales tipo halita [NaCl], dolomita [CaMg(CO32], calcita [CaCO3] y/o magnesita [MgCO3]. El As disuelto presenta concentraciones variables en 3 órdenes de magnitud, desde 3 hasta 581,7 µg/L, lo que supone un alto riesgo a la salud por exposición. La variabilidad espacio-temporal en las concentraciones de arsénico se explica por la variabilidad litológica del lugar, donde las diferentes capas de arcilla, limo y/o arena contendrían composiciones heterogéneas y variables de As. La correlación positiva moderada entre el arsénico y el hierro presentes sugiere la disolución y/o mineralización de fases amorfas de oxi-hidróxido de hierro asociadas con el arsénico haciendo posible su  movilización del As hacia el acuífero subterráneo. Las características físico-químicas de casi todos los pozos altamente contaminados, favorecen la viabilidad técnica de la mayoría los procesos comparados: coagulación con Fe(III y Al(III, adsorción sobre alúmina activada, intercambio iónico, filtración en lechos de arena recubierta con óxido de hierro (IHE-ADART, Remoción de Arsénico Asistida por Oxidación Solar, RAOS, nano-filtración y osmosis reversa.

    Full Text Available In this study, we analyze the dynamic interactions between the financial sectors and the business sectors in the ASEAN-4 countries (Indonesia, Malaysia, Thailand and Singapore. To do that, we apply the newly generalized version of the Vector Autoregressive Framework (VAR spillover index approach proposed by Diebold and Yilmaz (2012 as our method of analysis. Based on quarterly data of each variable over the period from the first quarter of 1984 to the fourth quarter of 2015 for the ASEAN-4 countries, this study finds that: 1 Spillovers between the variables move in a diverse manner over the period of analysis for each country, 2 The variable that acts as the dominant crisis transmitter in each country is different for each country, 3 The interdependence between the variables became stronger, both within and across the countries, during the crisis period. In particular, the business sectors played a leading role during the onset of the crisis, while the financial sectors took their places as the dominant source of spillovers as the crisis deepened. 4 Credit growth in Thailand was found to be the dominant transmitter of shocks to the ASEAN-3 countries. Overall, these results suggest that the strength and movement of the spillovers between the financial and business sectors changed from time to time along with the changes that happened in the economies.

  10. Electricity sector integration in West Africa

    International Nuclear Information System (INIS)

    Pineau, Pierre-Olivier

    2008-01-01

    Regional and global integration initiatives push for more electricity sector integration everywhere in the world, including West Africa. The creation of the West African Power Pool (WAPP) in 2000 and important investments under this new structure in 2006 are concrete actions that will result in a more integrated West African electricity sector. But will this integrated sector be more functional than the previous ones? Will the identified electricity sector problems be solved with the new power pool? This paper analyzes how power sector integration is presented by international institutions (the UN Economic Commission for Africa, World Energy Council and World Bank) and identifies three problematic issues with the current integration approach: lack of African ownership, unclear and conflicting reform objectives and uncertainty of integration outcomes

Se analizaron 26.799 empresas del sector real y 254 entidades del sector financiero, lo que dio como resultado mejores indicadores para el sector financiero y, dentro de este, se destacó la industria aseguradora. Sin embargo, es necesario que estos dos sectores mejoren su desempeño, ya que solo el 2,6 % de las empresas y entidades estudiadas es eficiente.

    De Costa, Ayesha; Diwan, Vinod

    2007-12-01

    This paper aims to empirically demonstrate the size and composition of the private health care sector in one of India's largest provinces, Madhya Pradesh. It is based on a field survey of all health care providers in Madhya Pradesh (60.4 million in 52,117 villages and 394 towns). Seventy-five percent of the population is rural and 37% live below poverty line. This survey was done as part of the development of a health management information system. The distribution of health care providers in the province with regard to sector of work (public/private), rural-urban location, qualification, commercial orientation and institutional set-up are described. Of the 24,807 qualified doctors mapped in the survey, 18,757 (75.6%) work in the private sector. Fifteen thousand one hundred forty-two (80%) of these private physicians work in urban areas. The 72.1% (67793) of all qualified paramedical staff work in the private sector, mostly in rural areas. The paper empirically demonstrates the dominant heterogeneous private health sector and the overall the disparity in healthcare provision in rural and urban areas. It argues for a new role for the public health sector, one of constructive oversight over the entire health sector (public and private) balanced with direct provision of services where necessary. It emphasizes the need to build strong public private partnerships to ensure equitable access to healthcare for all.

  15. Third sector primary care for vulnerable populations.

    Crampton, P; Dowell, A; Woodward, A

    2001-12-01

    This paper aims to describe and explain the development of third sector primary care organisations in New Zealand. The third sector is the non-government, non-profit sector. International literature suggests that this sector fulfils an important role in democratic societies with market-based economies, providing services otherwise neglected by the government and private for-profit sectors. Third sector organisations provided a range of social services throughout New Zealand's colonial history. However, it was not until the 1980s that third sector organisations providing comprehensive primary medical and related services started having a significant presence in New Zealand. In 1994 a range of union health centres, tribally based Mäori health providers, and community-based primary care providers established a formal network -- Health Care Aotearoa. While not representing all third sector primary care providers in New Zealand, Health Care Aotearoa was the best-developed example of a grouping of third sector primary care organisations. Member organisations served populations that were largely non-European and lived in deprived areas, and tended to adopt population approaches to funding and provision of services. The development of Health Care Aotearoa has been consistent with international experience of third sector involvement -- there were perceived "failures" in government policies for funding primary care and private sector responses to these policies, resulting in lack of universal funding and provision of primary care and continuing patient co-payments. The principal policy implication concerns the role of the third sector in providing primary care services for vulnerable populations as a partial alternative to universal funding and provision of primary care. Such an alternative may be convenient for proponents of reduced state involvement in funding and provision of health care, but may not be desirable from the point of view of equity and social cohesion

    Sector 7-8 is the first sector of the LHC to become fully operational. All the magnets, cryogenic line, vacuum chambers and services are interconnected. The cool down of this sector can soon commence. LHC project leader Lyn Evans, the teams from CERN's AT/MCS, AT/VAC and AT/MEL groups, and the members of the IEG consortium celebrate the completion of the first LHC sector. The 10th of November was a red letter day for the LHC accelerator teams, marking the completion of the first sector of the machine. The magnets of sector 7-8, together with the cryogenic line, the vacuum chambers and the distribution feedboxes (DFBs) are now all completely interconnected. Sector 7-8 has thus been closed and is the first LHC sector to become operational. The interconnection work required several thousand electrical, cryogenic and insulating connections to be made on the 210 interfaces between the magnets in the arc, the 30 interfaces between the special magnets and the interfaces with the cryogenic line.

    In the last 25 years, the production sector in Spain has undergone important changes. Among these changes, the important growth of the services sector at the expense of the primary sector, the increasing flexibility of the labour market, and the rise in the female workforce could be considered as the most relevant ones. Spanish women have higher rates of unemployment, temporary jobs and part time contracts than Spanish men. Moreover, job access and work conditions are highly related to gender and social class. Because women are forced to compensate for the scarcity of social services for caring for young children and for dependent elderly, they become informal and socially unrecognised caregivers, preventing them from getting or holding a job, and significantly limiting their opportunities for professional development. These social conditions are closely related with the fact that work conditions for women involve higher temporality rates and shorter contracts than those of men, given the sectors and jobs in which they tend to work (due to segregation). Similarly, workers of the less privileged social classes have poorer work conditions. Thus, women of the lower income class are mainly suffering the worst job contracts and the poorest work conditions. More social services are needed to make it possible to attend to family needs and still be able to access and maintain a job contract. Policies tending to conciliate labour and family life are indispensable and should incorporate measures to equally distribute the house keeping activities between women and men.

    Full Text Available La importancia del control por parte de las mujeres de métodos anticonceptivos y aquellos que previenen la infección de enfermedades de transmisión sexual, especialmente el VIH/SIDA, es un tema que adquiere importancia en el marco del aumento de las mujeres afectadas por la epidemia. El objetivo de este trabajo, un estudio de poblaciones mediante encuestas con muestras probabilísticas transversal, es evaluar el conocimiento y viabilidad de uso del preservativo femenino en jóvenes universitarios utilizando una metodología cuantitativa. La muestra estuvo formada por 225 chicas y 105 chicos. Los resultados muestran que casi la mitad de los sujetos han oído hablar del preservativo femenino, pero el 98,8% nunca lo ha usado. Las variables que predicen la asociación de beneficios asociados al uso del preservativo femenino son, para los chicos, las actitudes frente a la sexualidad y para las chicas la disposición a probarlo y los costes. En cuanto a la disposición a usarlo, las variables más influyentes para los chicos son disposición a hablar con la pareja, la disposición a participar y la utilización de métodos anticonceptivos y, para las chicas, la disposición a recomendar el preservativo femenino y estar de acuerdo en que la mujer lo utilice. Estos resultados adquieren una relevancia especial en las investigaciones centradas en reducir el aumento de embarazos no deseados y casos de VIH/SIDA en la población de mujeres y abren nuevas perspectivas alrededor de esta temática.

    India's Universal Immunization Programme (UIP) provides basic vaccines free-of-cost in the public sector, yet national vaccination coverage is poor. The Government of India has urged an expanded role for the private sector to help achieve universal immunization coverage. We conducted a state-by-state analysis of the role of the private sector in vaccinating Indian children against each of the six primary childhood diseases covered under India's UIP. We analyzed IMS Health data on Indian private-sector vaccine sales, 2011 Indian Census data and national household surveys (DHS/NFHS 2005-06 and UNICEF CES 2009) to estimate the percentage of vaccinated children among the 2009-12 birth cohort who received a given vaccine in the private sector in 16 Indian states. We also analyzed the estimated private-sector vaccine shares as function of state-specific socio-economic status. Overall in 16 states, the private sector contributed 4.7% towards tuberculosis (Bacillus Calmette-Guérin (BCG)), 3.5% towards measles, 2.3% towards diphtheria-pertussis-tetanus (DPT3) and 7.6% towards polio (OPV3) overall (both public and private sectors) vaccination coverage. Certain low income states (Uttar Pradesh, Rajasthan, Madhya Pradesh, Orissa, Assam and Bihar) have low private as well as public sector vaccination coverage. The private sector's role has been limited primarily to the high income states as opposed to these low income states where the majority of Indian children live. Urban areas with good access to the private sector and the ability to pay increases the Indian population's willingness to access private-sector vaccination services. In India, the public sector offers vaccination services to the majority of the population but the private sector should not be neglected as it could potentially improve overall vaccination coverage. The government could train and incentivize a wider range of private-sector health professionals to help deliver the vaccines, especially in the low

  12. Health sector reform and public sector health worker motivation: a conceptual framework.

    Franco, Lynne Miller; Bennett, Sara; Kanfer, Ruth

    2002-04-01

    Motivation in the work context can be defined as an individual's degree of willingness to exert and maintain an effort towards organizational goals. Health sector performance is critically dependent on worker motivation, with service quality, efficiency, and equity, all directly mediated by workers' willingness to apply themselves to their tasks. Resource availability and worker competence are essential but not sufficient to ensure desired worker performance. While financial incentives may be important determinants of worker motivation, they alone cannot and have not resolved all worker motivation problems. Worker motivation is a complex process and crosses many disciplinary boundaries, including economics, psychology, organizational development, human resource management, and sociology. This paper discusses the many layers of influences upon health worker motivation: the internal individual-level determinants, determinants that operate at organizational (work context) level, and determinants stemming from interactions with the broader societal culture. Worker motivation will be affected by health sector reforms which potentially affect organizational culture, reporting structures, human resource management, channels of accountability, types of interactions with clients and communities, etc. The conceptual model described in this paper clarifies ways in which worker motivation is influenced and how health sector reform can positively affect worker motivation. Among others, health sector policy makers can better facilitate goal congruence (between workers and the organizations they work for) and improved worker motivation by considering the following in their design and implementation of health sector reforms: addressing multiple channels for worker motivation, recognizing the importance of communication and leadership for reforms, identifying organizational and cultural values that might facilitate or impede implementation of reforms, and understanding that reforms

    2000-08-01

    Full Text Available En América Latina, las reformas del sector de la salud han ido de la mano con los fenómenos sociales y económicos de la segunda mitad del siglo XX y han reflejado el concepto particular del "desarrollo" que ha predominado en distintos momentos. El estancamiento económico y el aumento del gasto social, fenómenos propios de los años sesenta, llevaron a la crisis del modelo de desarrollo basado en la "sustitución de importaciones", vigente desde principios de siglo, y dieron paso paulatinamente al modelo de "globalización" que tuvo inicio en los años ochenta. Del anterior modelo se pasó a una reestructuración de los procesos productivos y a políticas de ajuste económico que redundaron, irónicamente, en una agudización de la pobreza en América Latina. Dos han sido las fases de implementación de este nuevo modelo. La primera, denominada de "reforma social" o de "primera generación", partía del concepto de que la pobreza se reduce a una suma de carencias materiales cuya resolución radica en la repartición equitativa de un volumen fijo de bienes que posee la sociedad. Este marco conceptual, completamente desvinculado de toda connotación histórica y de la política económica, condujo a políticas sociales orientadas por entero a mitigar la pobreza mediante subsidios destinados a los sectores más necesitados. En la segunda fase del modelo de globalización, iniciada en los años noventa y denominada "de segunda generación" o de "postajuste", entraron en juego nuevas reglas económicas, basadas principalmente en la competencia internacional, la eficiencia productiva y la transparencia del mercado de capitales. Y si en la primera fase el concepto estratégico de la política social se centraba en combatir la pobreza, en la segunda pasó a convertirse en la búsqueda de la equidad, ya no entendida como la distribución pareja de un volumen fijo de bienes de capital, sino como el ofrecimiento sostenido de mayores y mejores

    Full Text Available Concentration is a situation in which market structure of a sector is controlled by a few firms. At the present time, many analyzing methods such as Herfindahl-Hirschman and N-Firm Concentration Indexes are used to determine market structure.According to market concentration indexes, higher concentration level means more monopolistic market structure, lower concentration level means more full competitive market structure. In this study concentration levels of media groups in Turkish journalism sector within the scope of traditional journalism and internet journalism was analyzed via N-Firm Concentration and H-H Indexes. As a result of the study, it’s seen that first four biggest media groups have monopolistic competition in internet journalism sector,and oligopol structure in traditional journalism sector.

    The policy has both national and European level ambitious program aimed at expansion of renewable energy and related to the reduction of greenhouse gas emissions. In the national action plan for renewable energy of the Federal Republic of Germany these goals are defined by 2020. The share of renewable energy in the provision of heat and cold should therefore rise from 6.6% to 15.5% of gross final energy consumption. According to the increasing importance of solar-thermal, near-surface and geothermal heat, the relative share of biomass is decreasing. However biomass makes with those listed in the national action plan with 79% an essential amount in regenerative heat market [BMU 2010]. For the pursuit of goals and reviews, the support measures and packages of measures which are initiated in this context, a regular and timely reporting on the development of the above objectives is mandatory. The diverse and growing reporting requirements such as in the EU directive on the promotion of renewable energy, require, however well-founded knowledge of the sector-specific energy consumption from renewable sources. While the data available for use of biogenic solid fuels in the sectors household and industry has improved significantly in recent years, for the sector commercial sector, trade, services (tertiary sector) reliable figures are still lacking. Against this background, the objective is to present study, in close cooperation with the Federal Environment Agency (UBA), the determination of the final energy consumption biogenic solid fuels in the tertiary sector in Germany for the year 2008. The basis is, in addition to the development of the current knowledge of the energy and heat consumption, the delimitation and characterization of the sector and the development of an extrapolation tools. The demand for this tool is its expandability and update possibility. From the industry-nonspecific and industry-specific input data can be derived, collecting for the extrapolation

    Full Text Available RESUMO O objetivo do trabalho foi elaborar um meio de cultura para avaliação da viabilidade polínica e determinar o número de grãos de pólen por antera e por flor de espécies de fisális. O trabalho foi desenvolvido de forma sequencial, onde grãos de pólen de Physalis (P. angulata,P. ixocarpa,P. minima,P. peruviana e P. pubescens foram submetidos à germinação em meio de cultura desenvolvido em quatro fases: verificação da concentração de ágar e pH, concentração de sacarose, nitrato de cálcio e ácido bórico. Para a contagem de grãos de pólen, cinco anteras foram coletadas entre cinco espécimes representativos de cada espécie, deixadas em repouso para ocorrência da deiscência e posteriormente adicionado ácido lático, para melhoria da visualização do grão de pólen. Após 48 horas o número de grãos de pólen foi quantificado com auxílio de câmara de Neubauer e o número de grãos de pólen por antera determinado por fórmula pré-estabelecida. Observou-se que todas as espécies possuem comportamento semelhante quanto às suas exigências para germinação do grão de pólen, sendo o pH do meio em torno de 5,4 e a concentração de ágar de 8 g L-1; todas as espécies mostram dependência de cálcio e boro para uma melhor viabilidade polínica, destacando-se P. minima em que a adição de boro não propiciou elevação acentuada na porcentagem de germinação. Quanto ao número de grãos de pólen as espécies podem ser divididas em dois grupos, com P. angulata,P. peruviana e P. pubescens com maior número de grãos de pólen por antera e por flor em relação a P. ixocarpa e P. minima.

    Full Text Available Globalization, deregulation and technological improvements have resulted in increase in M&A across the globe. There is enormous literature existing in the advanced economies. However, very little information is available regarding M&A in India. Various sectors have witnessed differential involvement in M&A activity indicating higher participation by some. Particularly, certain sectors such as financial services and pharmaceuticals demonstrate higher M&A activity. To emphasise differential importance of sectors in M&A activity, it is necessary to conduct a sector-wise analysis. Accordingly, this study attempts to investigate the differential representation of various sectors in M&A. Further, it explores the role played by India in the rising global M&A activity. In light of this, it specifies the factors driving consolidation in the financial sector globally.

  2. Efficiency of the Macedonian banking sector

    Full Text Available The subject of this paper is to measure the efficiency of the Macedonian banking sector by applying two approaches: firstly, comparative analysis on the efficiency indicators of the banking sector in the Republic of Macedonia and the countries of Central and Southeastern Europe (CSEE and secondly, Data Envelopment Analysis (DEA. The aim is to provide directions and guidelines for further strengthening of the Macedonian banking sector. According to the comparative analysis of the efficiency indicators (net interest margin and operating costs of the Macedonian banking sector and the countries of CSEE, the countries whose banking sector shows lower operating costs are characterized with a higher level of financial deepening and greater degree of financial intermediation. The high interest margins direct towards unsuitable allocation of financial resources and insufficient competitiveness in the domestic banking sector. When applying the DEA approach, it can be stated that the group of large banks marks the highest efficiency within the Macedonian banking sector. The high concentration degree of banking activities within the group of large banks with a leading role in determining the interest rates, results in a rigid interest policy of the banks. In the direction of strengthening the efficiency of the Macedonian banking sector as a whole, the obtained results show that it is necessary for the banks to be further consolidated so as to utilize the advantages of the economies of scale, increase competitiveness, offer a diversified structure of products, invest in new contemporary software solutions that will allow reinforcement of their employees’ productivity and long-term reduction of the operating costs, as well.

    Eighteen interplanetary sector boundary crossings observed at 1 AU during the period January 1971 to January 1974 by the magnetometer on the Imp 6 spacecraft was discussed. The events were examined on many different time scales ranging from days on either side of the boundary to high-resolution measurements of 12.5 vectors per second. Two categories of boundaries were found, one group being relatively thin (averaging approx. =10 4 km) and the other being thick (averaging approx. =10 6 km). In many cases the field vector rotated in a plane from polarity to the other. Only two of the transitions were null sheets. Using the minimum variance analysis to determine the normals to the plane of rotationa and assuming that this is the same as the normal to the sector boundary surface, it was found that the normals were close to ( 0 ) the ecliptic plane. The high inclination of the sector boundary surfaces during 1971--1973 verifies a published prediction and may be related to the presence of large equatorial coronal holes at this time. An analysis of tangential discontinuities contained in 4-day periods about our events showed that their orientations were generally not related to the orientations of the sector boundary surface, but rather their characteristics were about the same as those for discontinuities outside the sector boundaries. Magnetic holes were found in thick sector boundaries, at a rate about 3 times that elsewhere. The holes were especially prevalent near stream interfaces, suggesting that they might be related to the convergence and/or slip of adjacent solar wind streams

    Full Text Available The paper emphasises the role of the market-type mechanisms within the activity of the organisations from the public sector. The end of the 20th century was defined by the effects of the public sector reform. The public sector is placed within the cultural and political environment of each country and the reforms have aimed to redefine the structures of the state organisations in the economy and the relationships such as market-government, government-bureaucracy, government- citizens, bureaucracy-citizens, civil servants-politicians-citizens. The public sector reform, achieved at the managerial systems, organisational structures and regulations levels is accompanied by specific and structural reforms. Accepting the market-type mechanisms instead of bureaucratic mechanisms, meaning not the simple provision of public services but the creation of some governmental “actors”, functioning completely on commercial bases, supporting the development of the partnerships between the public and private sector, introducing privatisation is achieved in view of creating “the facilitating state”. We discuss about “facilities” such as citizens and society involvement in public businesses, making public administration more citizen-friendly and the state closer to the public need. The citizens’ involvement, as customers in the flow of the public service contributes to creating an organic ensemble characterised by two fundamental dimensions: level and type of influence of the customers and the private-public dichotomy. Synthesising, the relationships and market mechanisms enable to the public sector to get closer to the public needs and to create a modern administration based on efficiency, effectiveness and openness towards change.

    The long-term vision through scenarios corresponds to different histories of how the energy sector situation could be. The numbers that are obtained are only indicative of those histories and not the quantities of a projection of the future with which businesses plans are to be developed, these quantities serve to illustrate what can happen if certain changes occur either or of geopolitical, economic, technological or social nature. Its main function is the one of making reflect the central actors of the sector on the impacts and consequences that certain events occur. In relation to the renewable energies, in the last decades these have been reducing their participation in the Mexican energy sector. Evidently the Mexican energy sector, in the subject of technology, has decided to take the function of preservative follower due in a large extent to the form in which the management of the operative organizations of the same one is made. [Spanish] La vision a largo plazo a traves de escenarios corresponde a diferentes historias de como podria ser la situacion del sector energia. Los numeros que se obtienen solo son indicativos de esas historias y no las cantidades de una proyeccion del futuro con la cual se desarrollen planes de negocios, estas cantidades sirven para ilustrar lo que puede pasar si ciertos cambios ocurren ya sea de naturaleza geopolitica, economica, tecnologica o social. Su principal funcion es la de hacer reflexionar a los actores centrales del sector sobre los impactos y consecuencias de que se den ciertos eventos. En relacion con las energias renovables, en las ultimas decadas estas han ido reduciendo su participacion en el sector energetico mexicano. Evidentemente el sector energetico mexicano, en cuestion de tecnologia ha decidido tomar la funcion de seguidor conservador debido en gran parte a la forma en que se realiza la gestion de las entidades operativas del mismo.

    Status of the reforms in Lithuania's energy sector and preparation of updated Energy Strategy is presented in this article. The new Strategy has been worked out considering the conclusions of different studies as well as the changes that have taken place in Lithuania and restructuring of its energy sector, the guidelines of the European Union. The principal objectives of the country's energy sector consists in reliable and safe energy supply with minimum expenses, increasing efficiency of energy utilisation, introducing principles of market economy within the sector, reducing environmental impacts, preparing Lithuania's energy sector for integration into the EU. In the field of nuclear energy the top priority is to ensure the safety of Ignalina NPP. Ignalina NPP will only be operated if and as long as it is safe. Two most likely scenarios for the future operation of Ignalina NPP are analysed in the draft Strategy. According to scenario 1, reactor 1 and 2 are to be operated half of the design service life, until 2005 and 2010 respectively, i.e. until the gap between the graphite and fuel channels reaches the critical margin. In accordance with the second scenario, the fuel channels are to be replaced as envisaged in the design, after which the reactors may be operated for another 10 - 15 years

    Projects with large infrastructures, particularly those in the field of energy, provide a strong boost to certain industrial sectors in the country. In the case of Spain, the policy of direct management 'by components' of these projects - hydroelectric power plants, petrochemical plants, thermoelectric plants and nuclear power plants - adopted by the electric utility owners has furthered not only the local equipment manufacturing industry but also the engineering sector. At present, with full implementation of the Single Market in sight, it is particularly interesting for Spain to continue building up a powerful engineering sector, increasing its size and usefulness, and extending its traditional areas of action to other technologies, more on the lines of engineering and consulting firms in the USA than in the rest of Europe. The intention is to endow our equipment and construction companies with the skills necessary to enable them to compete with large European conglomerates in their respective sectors. The structure of these conglomerates usually contains engineering capabilities which are not habitual in our industry. Examples are given, showing how this model has been used to compete and win awards for important international projects. A specific analysis has been made of the position of Spanish engineering and industry in nuclear power generation projects in the former Soviet Union and East European countries, in which large investments are expected to be made.

    Full Text Available It’s known in the literature that public-private partnerships (PPPs are one the main instruments that permit private collaboration in projects that are public otherwise. It’s also clear that their implementation is different depending on the rules of the countries, their market level of acceptance etc. The first objective of this paper is to revise PPPs projects in the water sector in Albania, seen in the context of alternative financing ways for joint-stock companies of Albanian water sector, due to the nature of the market (a developing emerging market, in the context of bad financial times after 2008 (the start of the international financial crisis. The second objective is to describe the development of the Albanian legislation for management contracts introduced for the first time in the waters and sanitation sector in 2004 and privatization practices in public sector. The main conclusion is that in the developing markets creating possibilities for private sector participation in the infrastructure public services (especially in the drinking water and sanitation sector will be seen with skepticism because of failed previous privatization practices or the sensitivity degree of the water sector related to the penetration level of private factor in the sector. Public finance will be explored as a convenient alternative.

  12. Performance measurement in transport sector analysis

    Full Text Available The article analyses the following issues: 1. Performance measurement in literature. The performance measurement has an important role to play in the efficient and effective management of organizations. Kaplan and Johnson highlighted the failure of the financial measures to reflect changes in the competitive circumstances and strategies of modern organizations. Many authors have focused attention on how organizations can design more appropriate measurement systems. Based on literature, consultancy experience and action research, numerous processes have been developed that organizations can follow in order to design and implement systems. Many frameworks have been proposed that support these processes. The objective of such frameworks is to help organizations define a set of measures that reflect their objectives and assess their performance appropriately. 2. Transport sector performance and its impacts measuring. The purpose of transport measurement is to identify opportunities enhancing transport performance. Successful transport sector management requires a system to analyze its efficiency and effectiveness as well as plan interventions if transport sector performance needs improvement. Transport impacts must be measurable and monitorable so that the person responsible for the project intervention can decide when and how to influence them. Performance indicators provide a means to measure and monitor impacts. These indicators essentially reflect quantitative and qualitative aspects of impacts at given time and places. 3. Transport sector output and input. Transport sector inputs are the resources required to deliver transport sector outputs. Transport sector inputs are typically: human resources, particularly skilled resources (including specialists consulting inputs; technology processes such as equipment and work; and finance, both public and private. 4.

    The aim was to identify similarities and differences between private practice and the National Health Service (NHS) in practitioners' experiences of delivering acupuncture to treat pain. We wished to identify differences that could affect patients' experiences and inform our understanding of how trials conducted in private clinics relate to NHS clinical practice. Acupuncture is commonly used in primary care for lower back pain and is recommended in the National Institute for Health and Clinical Excellence's guidelines. Previous studies have identified differences in patients' accounts of receiving acupuncture in the NHS and in the private sector. The major recent UK trial of acupuncture for back pain was conducted in the private sector. Semi-structured qualitative interviews were conducted with 16 acupuncturists who had experience of working in the private sector (n = 7), in the NHS (n =3), and in both the sectors (n = 6). The interviews lasted between 24 and 77 min (median=49 min) and explored acupuncturists' experiences of treating patients in pain. Inductive thematic analysis was used to identify similarities and differences across private practice and the NHS. The perceived effectiveness of acupuncture was described consistently and participants felt they did (or would) deliver acupuncture similarly in NHS and in private practice. In both the sectors, patients sought acupuncture as a last resort and acupuncturist-patient relationships were deemed important. Acupuncture availability differed across sectors: in the NHS it was constrained by Trust policies and in the private sector by patients' financial resources. There were greater opportunities for autonomous practice in the private sector and regulation was important for different reasons in each sector. In general, NHS practitioners had Western-focussed training and also used conventional medical techniques, whereas private practitioners were more likely to have Traditional Chinese training and to practise

    Two programs have been developed for observation and control of the AGS vacuum system, which include these notable features: they incorporate a graphical user interface, and they are driven by a relational database which describes the vacuum system. The vacuum system comprises some 440 devices organized into 28 vacuum sectors. The Status Display Program invites menu selection of a sector, interrogates the relational database for relevant vacuum devices, acquires live readbacks, and posts a graphical display of their status. The Sector Conditioning Program likewise invites sector selection, produces the same status display, and also implements process control logic on the sector devices to pump the sector down from atmospheric pressure to high vacuum over a period extending for several hours. As additional devices are installed in the vacuum system, the devices are likewise added to the relational database; these programs then automatically include the new devices. 2 refs., 1 fig

  16. Embodied energy use in China's industrial sectors

    As the world’s top energy consumer, China is facing a great challenge to solve its energy supply issue. In this paper energy use from all industrial sectors in China’s economy of 2007 was explored by conducting an extended environmental input–output analysis. We compare the energy consumption embodied in the final demand for goods and services from 29 sectors with the energy demand required for the actual production process in each sector. Two different viewpoints for sectoral energy use have been presented: energy use is directly allocated to the producer entity, and energy use is reallocated to sector’s supply chain from consumption perspective. Our results show that considerable amount of energy use is embodied in the supply chain, especially for “Construction” and “Other Service Activities” sectors, which is not detected if energy use is allocated on a production basis. When further dividing embodied energy consumption into direct energy consumption and indirect energy consumption, total indirect energy consumption is much higher than that of total direct energy consumption, accounting for 80.6% of total embodied energy consumption in 2007. Our results provide a more holistic picture on sectoral energy consumption and therefore can help decision-makers make more appropriate policies. - Highlights: ► A hybrid IO-LCA model was employed to analyze China’s energy use at sectoral level. ► A case study on China’s sectoral energy consumption is done. ► Construction and service sectors are actually energy intensive from the supply chain perspectives. ► Upstream and downstream ectoral collaboration along the whole supply chain is necessary. ► Energy conservation policies should be based upon a comprehensive analysis on sectoral energy use.

    The present study examined the differences between physicians working in public and private health care in strenuous working environments (presence of occupational hazards, physical violence, and presenteeism) and health behaviours (alcohol consumption, body mass index, and physical activity). In addition, we examined whether gender or age moderated these potential differences. Cross-sectional survey data were compiled on 1422 female and 948 male randomly selected physicians aged 25-65 years from The Finnish Health Care Professionals Study. Logistic regression and linear regression analyses were used with adjustment for gender, age, specialisation status, working time, managerial position, and on-call duty. Occupational hazards, physical violence, and presenteeism were more commonly reported by physicians working in the public sector than by their counterparts in the private sector. Among physicians aged 50 years or younger, those who worked in the public sector consumed more alcohol than those who worked in the private sector, whereas in those aged 50 or more the reverse was true. In addition, working in the private sector was most strongly associated with lower levels of physical violence in those who were older than 50 years, and with lower levels of presenteeism among those aged 40-50 years. The present study found evidence for the public sector being a more strenuous work environment for physicians than the private sector. Our results suggest that public healthcare organisations should pay more attention to the working conditions of their employees.

    Full Text Available El primer y segundo molar son los dientes que se pierden más a menudo debido a la enfermedad periodontal y al exceso de fuerzas oclusales. A pesar de la frecuencia del edentulismo parcial del sector posterior raramente se ubican los implantes más allá de los premolares debido al aumento del índice de fallos. El escaso volumen óseo y la pobre mineralización del sector posterior del maxilar comprometen la viabilidad de las rehabilitaciones con implantes a largo plazo. Además, la cresta ósea a nivel del seno maxilar, en el maxilar atrófico, no suele permitir el anclaje de implantes de 10 mm. Se han propuesto varias técnicas para rehabilitar el sector posterior del maxilar atrófico: implantes cortos, extensiones protésicas, injerto sinusal, implante cigomático. El implante pterigoideo es otro de los posibles tratamientos para rehabilitar el sector posterior del maxilar atrófico. Anclado en el hueso cortical de la apófisis del esfenoides el implante pterigoideo evita la necesidad de injertar o utilizar extensiones protésicas. El objetivo de este artículo es analizar las indicaciones, la técnica, complicaciones y supervivencia del implante pterigoideo en el sector posterior del maxilar atrófico.The first and second molar are the teeth most commonly lost in the maxilla, mainly due to periodontal disease and excessive occlusal force. 1 Although partial edentulism of the posterior maxilla is common, implants are seldom placed distal to the premolars because failure rates in the posterior maxilla have historically been high. Poor volume and low density of bone are the worst conditions for long-term anchorage in the maxilla. 7 Moreover, bone under the maxillary sinus, in the atrophic maxilla, is usually insufficient to enable placement of 10 mm implants. Several techniques have been proposed to restore the atrophic posterior maxilla: short implants, prosthetic cantilevers, sinus bone graft, zigomatic fixtures. Pterygoid implants are

    Full Text Available The public sector in developed countries went through various forms of transformation in the twentieth century. The expansion of the public sector resulted in high levels of public spending in developed countries. The financial crisis of 2008 led to recessions in the economies of developed countries, the public debt growth, and actualized the issue of the public sector optimal size and efficiency. This study analysed the public sector efficiency in 19 developed countries. The analysis focuses on the relationship between the size of public expenditure and economic growth in the global financial crisis and the measures implemented. The aim of the research in this paper is a comparison of total and partial efficiency of the public sector in developed countries, in order to determine the characteristics of the public sector operations. The comparison covers the areas of the public sector operations in order to identify sources of inefficiency. Partial and overall efficiency of countries are analysed with different size and concept of the public sector, to determine the relationship between the public sector size, efficiency and welfare of citizens. The research results clearly indicate (unjustified state intervention in developed countries.

    Adshead, Peter; Cui, Yanou; Shelton, Jessie

    2016-01-01

    In a broad class of theories, the relic abundance of dark matter is determined by interactions internal to a thermalized dark sector, with no direct involvement of the Standard Model (SM). We point out that these theories raise an immediate cosmological question: how was the dark sector initially populated in the early universe? Motivated in part by the difficulty of accommodating large amounts of entropy carried in dark radiation with cosmic microwave background measurements of the effective number of relativistic species at recombination, N eff , we aim to establish which admissible cosmological histories can populate a thermal dark sector that never reaches thermal equilibrium with the SM. The minimal cosmological origin for such a dark sector is asymmetric reheating, when the same mechanism that populates the SM in the early universe also populates the dark sector at a lower temperature. Here we demonstrate that the resulting inevitable inflaton-mediated scattering between the dark sector and the SM can wash out a would-be temperature asymmetry, and establish the regions of parameter space where temperature asymmetries can be generated in minimal reheating scenarios. Thus obtaining a temperature asymmetry of a given size either restricts possible inflaton masses and couplings or necessitates a non-minimal cosmology for one or both sectors. As a side benefit, we develop techniques for evaluating collision terms in the relativistic Boltzmann equation when the full dependence on Bose-Einstein or Fermi-Dirac phase space distributions must be retained, and present several new results on relativistic thermal averages in an appendix.

Here we demonstrate that the resulting inevitable inflaton-mediated scattering between the dark sector and the SM can wash out a would-be temperature asymmetry, and establish the regions of parameter space where temperature asymmetries can be generated in minimal reheating scenarios. Thus obtaining a temperature asymmetry of a given size either restricts possible inflaton masses and couplings or necessitates a non-minimal cosmology for one or both sectors.

    Full Text Available Abstract By reviewing economic performance, two main phenomena could be identified: The first phenomenon is prior to the third wave of the Industrial Revolution in which limited resources are the predominant input; in other words, physical and natural resources are much more credited than human resources. The second phenomenon resonates with the third wave of industrial revolution to the present time, suggesting the pivotal role of humans in production and accumulation of wealth, in which limited resources are no longer considered as predominant input. The present research seeks to understand the behavioral logic of the players of Iran's pharmaceutical sector so as to infer the innovative treatment of the firms in this sector. The concept of innovative system is indebted to the efforts economists and other scientists have made by analyzing economic development based upon technological development. Meanwhile, sectoral innovation system (SIS is a tool for analyzing a technological sector in the context of evolutionary economics with an emphasis on institutional capabilities. The structure of such an approach is composed of some components through which performance analysis of certain technological sector could be made possible. In research, we use expert panel with 12 experts from Universities, Companies, Governmental institutes. The current study wishes to explain structural model of institutional elements in this technological sector. Subsequently, in light of such an explanation, structural elements of this sector would be analyzed through identification of legal and regulatory framework, innovative culture, innovative infrastructure, financial resources, information resources, technology transfer mechanisms, commercialization support and marketing.

    In a broad class of theories, the relic abundance of dark matter is determined by interactions internal to a thermalized dark sector, with no direct involvement of the Standard Model (SM). We point out that these theories raise an immediate cosmological question: how was the dark sector initially populated in the early universe? Motivated in part by the difficulty of accommodating large amounts of entropy carried in dark radiation with cosmic microwave background measurements of the effective number of relativistic species at recombination, N eff , we aim to establish which admissible cosmological histories can populate a thermal dark sector that never reaches thermal equilibrium with the SM. The minimal cosmological origin for such a dark sector is asymmetric reheating, when the same mechanism that populates the SM in the early universe also populates the dark sector at a lower temperature. Here we demonstrate that the resulting inevitable inflaton-mediated scattering between the dark sector and the SM can wash out a would-be temperature asymmetry, and establish the regions of parameter space where temperature asymmetries can be generated in minimal reheating scenarios. Thus obtaining a temperature asymmetry of a given size either restricts possible inflaton masses and couplings or necessitates a non-minimal cosmology for one or both sectors. As a side benefit, we develop techniques for evaluating collision terms in the relativistic Boltzmann equation when the full dependence on Bose-Einstein or Fermi-Dirac phase space distributions must be retained, and present several new results on relativistic thermal averages in an appendix.

    2005-05-01

    Retinitis pigmentosa (RP) is one of the most common hereditary retinal dystrophies and causes of visual impairment affecting all age groups. The reported incidence varies, but is considered to be between 1 in 3,000 to 1 in 7,000. Sector retinitis pigmentosa is an atypical form of RP that is characterized by regionalized areas of bone spicule pigmentation, usually in the inferior quadrants of the retina. A 57-year-old Hispanic man with a history of previously diagnosed retinitis pigmentosa came to the clinic with a longstanding symptom of decreased vision at night. Bone spicule pigmentation was found in the nasal and inferior quadrants in each eye. He demonstrated superior and temporal visual-field loss corresponding to the areas of the affected retina. Clinical measurements of visual-field loss, best-corrected visual acuity, and ophthalmoscopic appearance have remained stable during the five years the patient has been followed. Sector retinitis pigmentosa is an atypical form of RP that is characterized by bilateral pigmentary retinopathy, usually isolated to the inferior quadrants. The remainder of the retina appears clinically normal, although studies have found functional abnormalities in these areas as well. Sector RP is generally considered a stationary to slowly progressive disease, with subnormal electro-retinogram findings and visual-field defects corresponding to the involved retinal sectors. Management of RP is very difficult because there are no proven methods of treatment. Studies have shown 15,000 IU of vitamin A palmitate per day may slow the progression, though this result is controversial. Low vision rehabilitation, long wavelength pass filters, and pedigree counseling remain the mainstay of management.

  14. Hidden-Sector Dynamics and the Supersymmetric Seesaw

    Campbell, Bruce A; Maybury, David W

    2008-01-01

    In light of recent analyses that have shown that nontrivial hidden-sector dynamics in models of supersymmetry breaking can lead to a significant impact on the predicted low-energy supersymmetric spectrum, we extend these studies to consider hidden-sector effects in extensions of the MSSM to include a seesaw model for neutrino masses. A dynamical hidden sector in an interval of mass scales below the seesaw scale would yield renormalization-group running involving both the anomalous dimension from the hidden sector and the seesaw-extended MSSM renormalization group equations (RGEs). These effects interfere in general, altering the generational mixing of the sleptons, and allowing for a substantial change to the expected level of charged-lepton flavour violation in seesaw-extended MSSM models. These results provide further support for recent theoretical observations that knowledge of the hidden sector is required in order to make concrete low-energy predictions, if the hidden sector is strongly coupled. In parti...

    This thesis focuses on the technologies related to CO{sub 2} capture and geological storage. The main objective of this study is to perform an analysis of the technical potential of geological sequestration of CO{sub 2} in the oil and gas sector in Brazil. Climate changes are directly related to emissions of greenhouse gases. Mainly, are related to increased carbon dioxide emissions due to the use of fossil fuels. To mitigate climate changes there are technologies that have the purpose of promoting the reduction of emissions of greenhouse gases such as the Geological Sequestration of CO{sub 2}. Thus, the study presents a description of the stages of the geological sequestration of CO{sub 2} and the state of the art of the technology in Brazil and worldwide. In addition, is presented the capacity for storage of the Brazilian sedimentary basins. Finally, this thesis analyzes the application of the described technologies in two stationary sources of great importance: refineries and oil and gas production fields. (author)

    We study the normative implications of a New Keynesian model featuring intersectoral trade of intermediate goods between two sectors that produce durables and non-durables. The interplay between durability and sectoral production linkages fundamentally alters the intersectoral stabilization trade....... Aggregating durable and non-durable inflation depending on the relative degrees of sectoral price stickiness may induce a severe bias. Input materials attenuate the response of sectoral inflations to movements in the real marginal costs, so that the effective slopes of the sectoral supply schedules...

    In this study we have analysed different options to apply emissions trading for greenhouse gas emissions to the transport sector. The main focus has been on the EU transport sector and the possibility to include it in the current EU ETS in the trading period beginning in 2013. The purpose was to study how different alternatives will affect different actors. Focus has been on three sub-sectors; road transport, aviation and shipping. The railway sector has only been treated on a general level. The study includes the following three parts: 1. An economic analysis of the consequences of greenhouse gas emissions trading for the transport sector including an analysis of how the total cost for reaching an emission target will be affected by an integrated emissions trading system for the transport sector and the industry (currently included sectors) compared to separate systems for the sectors, 2. An analysis of design possibilities for the different sub-sectors. Discussion of positive and negative aspects with different choices of design parameters, such as trading entity, covered greenhouse gases, allocation of emission allowances and monitoring systems, 3. Examination of the acceptance among different actors for different options of using greenhouse gas emissions trading in the transport sector. When setting up an emissions trading scheme there are a number of design parameters that have to be analysed in order to find an appropriate system, with limited administrative and transaction costs and as small distortions as possible to competitiveness

    Full Text Available Aim/purpose - The aim of the article is to present the essence of ex post approach to sectoral regulation, to show the advantages and disadvantages of ex post regulation and to answer the question whether it is worth using in the electricity sector. Design/methodology/approach - For this purpose, a critical analysis of expert literature was made and an empirical analysis of countries that have applied ex post regulation in the electricity sector in the European Union. Two research methods were used: a case study and a comparison of changes in price and quality of services. The research period covered the period 2000-2016. Findings - It was found that ex post regulation reduces regulatory costs, does not adversely affect the quality of service and long-term rates, gives businesses the freedom of decision-making and the ability to react quickly to changes in the economy. The main disadvantages of ex post regulation are the tendency for companies to over-estimate bills for consumers, the difficulty of pursuing claims by consumers and the need to shift regulatory risk to consumers. Research implications/limitations - In the paper there was identified a research gap, i.e. the effects of ex post regulation in the electricity sector in European Union countries where such regulation was applied. Identifying the research gap will help us understand what are the advantages and disadvantages of ex post regulation and will create a model for when it is good moment to implement this in the economy. Besides identifying the research gap, further studies will be required over ex post regulation. Originality/value/contribution - The additional value of the paper is the study of ex post regulation, its essence and types. The article analyzed the effects of ex post regulation in the electricity sector and provided valuable insights into the potential risks associated with this approach to economic regulation.

  8. Communication in third sector organisations

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Third sector organisations favour the social development due to their capacity to produce human and social capital in society (Putman, 2001. In order to achieve social welfare third sector organisations need to produce a positive change in the relations among individuals, groups and institutions in a society. The expectations about the third sector organisations’ transparency and capacity to tackle social problems are increasing worldwide. In Mexico, this problematic is more complex because there is a low level of professionalism, transparency, accountability and participation culture in the organized civil society (ITAM, 2010. The development of the organized civil society in Mexico will depend to a great extent on its capacity to communicate its values to society and achieve a cultural and social change. Therefore, the third sector organisations must adopt strategic initiatives to reinforce their credibility and reputation, because the public and private donors are increasingly more demanding in their criteria to grant resources to social projects; and because the Mexican society has a low participation level and faces increasingly more complex social problems.

    International Nuclear Information System (INIS)

    1996-01-01

    In recent years Mexico has implemented remarkable structural changes in its economy. However, until recently its large and key energy sector was largely unreformed. This is now changing. In 1995 the Mexican Government introduced legislative changes permitting private sector involvement in natural gas storage, transportation and distribution. Subsequent directives set up a detailed regulatory framework. These developments offer considerable promise, not only for natural gas sector development but also for growth in the closely linked electricity sector. This study analyses the changes which have taken place and the rationale for the regulatory framework which has been established. The study also contains recommendations to assist the Government of Mexico in effectively implementing its natural gas sector reforms and in maximizing the benefits to be realised through the new regulatory framework.

    2017-05-01

    Full Text Available It has been widely assumed in the literature that public sector organization operates in a different way compared to private sector organization. This paper intends to contribute to develop further this issue by investigating whether the relationship between worker efforts differs significantly both in the public and in the private sector. By drawing on data from the Monthly Employment Survey (PME, Brazil 2003–2012, and proxies for worker effort (unpaid overtime work and absences, it was observed, initially, significant differences between worker’s profiles depending on the sector they are employed. In turn, the estimation results of the dynamic panel models confirm that the level of worker effort alters according to their switches from one sector to another in the labor market. Briefly, public sector workers do not tend to do unpaid overtime work comparable to those in private sector, and they are more likely to be absent at work.

    The waste management section of this report deals with two sectors: land disposal of solid waste and wastewater treatment. It provides background information on the type of emissions that contribute to the greenhouse gases from these two sectors, presents both sector current status in Lebanon, describes the methodology followed to estimate the corresponding emissions, and presents the results obtained regarding greenhouse emissions. The total methane emissions from solid waste disposal on land are 42.804 Gg approximately. There are no emissions from wastewater and industrial handling systems because, for the target year 1994, there was no treatment facilities in Lebanon. The wastewater (municipal, commercial and industrial) was directly discharged into the sea, rivers, ravines or septic tanks which indicate that methane or nitrous oxide emissions are significant if not nonexistent. Note that this situation will change in the future as treatment plants are being constructed around the country and are expected to come into operation by the year 2000

    2015-06-01

    We introduce a new paradigm in Composite Dark Sectors, where the full Standard Model (including the Higgs boson) is extended with a strongly-interacting composite sector with global symmetry group G spontaneously broken to H is contained in G. We show that, under well-motivated conditions, the lightest neutral pseudo Nambu-Goldstone bosons are natural dark matter candidates for they are protected by a parity symmetry not even broken in the electroweak phase. These models are characterized by only two free parameters, namely the typical coupling g D and the scale f D of the composite sector, and are therefore very predictive. We consider in detail two minimal scenarios, SU(3)/[SU(2) x U(1)] and [SU(2) 2 x U(1)]/[SU(2) x U(1)], which provide a dynamical realization of the Inert Doublet and Triplet models, respectively. We show that the radiatively-induced potential can be computed in a five-dimensional description with modified boundary conditions with respect to Composite Higgs models. Finally, the dark matter candidates are shown to be compatible, in a large region of the parameter space, with current bounds from dark matter searches as well as electroweak and collider constraints on new resonances.

    Nowadays the treatment of the solid and liquid remainders in the municipal slaughter houses is small because of the idea that the treatment is expensive; nevertheless, it is important to take advantage of them, since this can reduce to the environmental impacts they cause, as well as the discharge of greenhouse effect gas. The use of bio digesters for the treatment of these remainders has become an efficient process to avoid the exit of methane gas to the atmosphere, taking advantage of the biogas and other residues to produce electricity. The elaboration of a technical-economical evaluation of a pilot plant shows the costs of investment, maintenance, as well as the income that can be obtained by the total usage of these residues and the savings in the electrical power consumption. The analysis of this study demonstrates that the use of biogas through bio-digesters for the generation of electrical energy is a profitable option for the treatment of the residues, because the income by the sale of compost, blood flour, as well as the diminution of the electrical tariff, justifies the initial investment. These projects will be more attractive, if they use financing and are registered as MDL projects. [Spanish] Actualmente el tratamiento de los desechos solidos y liquidos en los rastros y mataderos municipales es poco pues se tiene la idea de que el tratamiento es costoso; sin embargo, es importante que se aprovechen ya que esto puede reducir los impactos ambientales que provocan, asi como la emision de gases de efecto invernadero. El uso de biodigestores para el tratamiento de estos desechos, se ha convertido en un proceso eficiente para evitar la salida de gas metano a la atmosfera, aprovechando el biogas y otros residuos para producir electricidad.

    An exercise made through an approach group (expert in the subject) identified which were the main perceived obstacles for the penetration of the renewable energies in the Mexican energy sector. The perception of the group is that the perceived obstacles do not tend to be technical and that as of today, they depend more on political-legal aspects, administrative-institutional economic-financial. It is considered that the renewable energies, with some exceptions, were used mainly in a scheme of generating units of useful energy, either electricity or heat-cold or for process or environmental conditioning, are relatively small and therefore with a high dispersion in the national territory. This vision is equivalent to what it is known as distributed generation in the electrical sector. [Spanish] Un ejercicio realizado a traves de un grupo de enfoque (expertos en el tema) identifico cuales eran los principales obstaculos percibidos para la penetracion de las energias renovables en el sector energetico mexicano. La percepcion del grupo es que los obstaculos percibidos no tienden a ser tecnicos y que en el presente, estos dependen mas de aspectos politicos-legales, economicos-financieros y administrativos-institucionales. Se considera que las energias renovables, con algunas excepciones, se utilizaran principalmente en un esquema de unidades generadoras de energia util, ya sea electricidad o calor-frio para proceso o acondicionamiento ambiental, que son relativamente pequenas y por lo tanto con una alta dispersion en el territorio nacional. Esta vision es equivalente a lo que se conoce como generacion distribuida en el sector electrico.

  3. Transformation of the Polish Banking Sector

    Full Text Available In the post-war period the banking system in Poland underwent two important system transitions: after 1946 and after 1989. The third transformation began after May 1, 2004, but it did not have a systemic character. The Polish banking sector started to operate on the Single European Market. The first part of the paper is devoted to the problems of the banks transformations after 1989 with a special focus on the quantitative development of banks in 19892008, and on subsequent privatisation and consolidation processes. The former intensified in 19891999, and the latter in 19992002. The consolidation process was very noticeable in the sector of cooperative banks after 1994. The second part of the paper includes an economic and financial analysis of the banks. A lot of attention was paid to the liquidity of the banking sector. It was assessed as good, which was confirmed by a short-term rating of Moodys and by the Financial Stability Report 2009, published by the National Bank of Poland in June 2009. The comparison of the net profit of the banking sector in 19972008 shows its dependence on the economic situation and policy. The number of banks with capital adequacy ratio well above the minimum required by the banking supervision is rising. The financial power ratings are not favorable for the domestic banks. The third part of the paper focuses on the development directions of the Polish banking sector. It may be concluded on the basis of the analysis that privatisation and consolidation processes will be continued. They will concentrate on the capital of foreign banks already operating in Poland. As compared with individual foreign banks, the potential of the Polish banking sector is week. The fourth part of the paper focuses on the presentation Polish banking sector in the context of European Union banking sector. The paper finishes with conclusions. Generally, Polish banks have to implement a strategy to enable them to compete on the Single

    1989-12-01

    Projects supported by the Directorate for Population (S&T/POP) of the U.S. Agency for International Development and aimed at increasing for-profit private sector involvement in providing family planning services and products are described. Making products commercially available through social-marketing partnerships with the commercial sector, USAID has saved $1.1 million in commodity costs from Brazil, Dominican Republic, Ecuador, Indonesia, and Peru. Active private sector involvement benefits companies, consumers, and donors through increased corporate profits, healthier employees, improved consumer access at lower cost, and the possibility of sustained family planning programs. Moreover, private, for-profit companies will be able to meet service demands over the next 20 years where traditional government and donor agency sources would fail. Using employee surveys and cost-benefit analyses to demonstrate expected financial and health benefits for businesses and work forces, S&T/POP's Technical Information on Population for the Private Sector (TIPPS) project encourages private companies in developing countries to invest in family planning and maternal/child health care for their employees. 36 companies in 9 countries have responded thus far, which examples provided from Peru and Zimbabwe. The Enterprise program's objectives are also to increase the involvement of for-profit companies in delivering family planning services, and to improve the efficiency and effectiveness of private volunteer organizations in providing services. Projects have been started with mines, factories, banks, insurance companies, and parastatals in 27 countries, with examples cited from Ghana and Indonesia. Finally, the Social Marketing for Change project (SOMARC) builds demand and distributes low-cost contraceptives through commercial channels especially to low-income audiences. Partnerships have been initiated with the private sector in 17 developing countries, with examples provided from

    The study of CP violation in the baryon sector is still a relatively new field and offers the possibility to make many CP measurements which could complement those performed in the meson sector. This is especially true of late given the large number of baryons currently being produced at the LHC. Such measurements could help further over-constrain the CKM unitary triangle, as well as furthering our understand of baryongenesis. These proceedings will give an overview of the current state of the search for CP violation in the baryon sector.

    2011-01-01

    Highlights: → We conduct a decomposition exercise of the South African electricity consumption. → The increase in electricity consumption was due to output and structural changes. → The increasing at a low rate electricity intensity was a decreasing factor to consumption. → Increases in production were proven to be part of the rising trend for all sectors. → Only 5 sectors' consumption were negatively affected by efficiency improvements. -- Abstract: South Africa's electricity consumption has shown a sharp increase since the early 1990s. Here we conduct a sectoral decomposition analysis of the electricity consumption for the period 1993-2006 to determine the main drivers responsible for this increase. The results show that the increase was mainly due to output or production related factors, with structural changes playing a secondary role. While there is some evidence of efficiency improvements, indicated here as a slowdown in the rate of increase of electricity intensity, it was not nearly sufficient to offset the combined production and structural effects that propelled electricity consumption forward. This general economy-wide statement, however, can be misleading since the results, in essence, are very sector specific and the inter-sectoral differences are substantial. Increases in production were proven to be part of the rising trend for all sectors. However, only five out of fourteen sectors were affected by efficiency improvements, while the structural changes affected the sectors' electricity consumption in different ways. These differences concerning the production, structural and efficiency effects on the sectors indicate the need for a sectoral approach in the energy policy-making of the country rather than a blanket or unilateral economy-wide approach.

    Nigeria has been plagued with acute power shortages due to poor performance of its power sector. Several policies and reforms have been implemented by the government to address the poor performance of the power generation, transmission and distribution sectors of the electricity industry. Also various strategies were employed by the government which includes encouraging private sector participation, diversification of the energy generation sources and promoting energy efficiency for sustainable development. In addition the government has spent billions of dollars since 2001 in the construction of new power generation facilities, transmission lines and distribution centers to boost the power supply. It has deregulated the generation and distribution sectors to encourage private sector participation and empowers the Energy Commission of Nigeria to embark on programs and strategies that can boost energy generation from renewable sources. This paper examined the country's energy sources and the power sector reforms adopted by the government. The paper also outlined some recommendations based on reforms implemented by other countries with similar resources to Nigeria which yielded positive results. - Highlights: • Available resources for power generation in Nigeria. • Power sector challenges, policies and reforms. • Implications of the reforms implemented. • Recommendations for improving the sector's performance.

    Do economic considerations shape attitudes toward immigration? In this article, we consider the relationship between economic interests and immigration preferences by examining how developments in individuals' sectors of employment affect these views. Using survey data across European countries from 2002 to 2009 and employing new measures of industry-level exposure to immigration, we find that sectoral economies shape opinions about immigration. Individuals employed in growing sectors are more likely to support immigration than are those employed in shrinking sectors. Moreover, the economic context matters: Making use of the exogenous shock to national economies represented by the 2008 financial crisis, we show that sector-level inflows of immigrant workers have little effect on preferences when economies are expanding, but that they dampen support for immigration when economic conditions deteriorate and confidence in the economy declines. These sectoral effects remain even when controlling for natives' views about the impact of immigration on the national economy and culture. When evaluating immigration policy, individuals thus appear to take into account whether their sector of employment benefits economically from immigration.

    Full Text Available La región de Sucre, en Colombia, ha tenido bajo desarrollo en los últimos años, a pesar de su importancia en el sector agropecuario. La producción pecuaria, que ocupa la mayor área de Sucre, es practicada en sistema extensivo lo que ha causado subutilización de las tierras en la región y sobreutilización en otras áreas. En ese escenario, el gobierno ha creado programas con el fin de desarrollar la región, donde puede ser citado como ejemplo en el Plan Nacional de Desarrollo la producción Yuca industrial en la región y la construcción de la planta Almidones de Sucre S.A. Delante de dos producciones importantes en la región, Ganadería y yuca, el presente trabajo tuvo como objetivo analizar la viabilidad económica de ambas para identificar cuál es la más rentable en la región de Toluviejo-Sucre. Fueron utilizados los indicadores económicos Valor Neto Actual [VNA], Tasa Interna de Retorno [TIR], y el “payback” descontado.

Although South Africa dropped in the global competitiveness ranking, the property sector of South Africa remains very competitive. To survive in a competitive sector, firms around the world practice competitive intelligence(CI. Although the use of CI has been examined in other sectors in South Africa, no study on CI practice has been conducted in the property sector. Objectives: The objective of this research was to establish the extent to which the property sector of South Africa practices CI. Method: This research was quantitative in nature and a web-based questionnaire was used to collect data from estate agencies in the South African property sector. Results: The results indicate that the South African property sector is very competitive and estate agencies practice CI to gain competitive advantage and make quality decisions.Moreover, the results reveal that the property sector practice CI legally and ethically. The results indicate that the majority of estate agencies are very small employing at most five employees and make at most 5 million Rands annual turnover. Conclusion: The South African property sector ethically and legally practices CI to gain competitive advantage and to aid in making quality decisions.

    2017-01-01

    Full Text Available This paper highlights the importance of knowledge management in Slovenian public sector organizations. Knowledge management has received a lot of attention in the past two decades, however in the public sector it is still under-researched. The global financial and economic crisis revealed some important organizational weaknesses in the Republic of Slovenia, some particularly due to the ineffectiveness of the Slovenian public sector, which ranks amongst the worst in the Euro zone. Authors argue that a stronger commitment to knowledge management, which is currently unused in the Slovenian public sector, represents an opportunity to coordinate and exploit public sector organizational knowledge resources. After analysing existing literature, authors have identified examples of good practices from foreign countries that could be partially transferred and adapted into the Slovenian environment. Since the efficient use of knowledge is linked to the performance of public sector organizations, the paper suggests that successful implementation of knowledge management initiatives should result in a more efficient public sector and, indirectly, in improved international public sector competitiveness rankings. This paper is also considered to be important for public sector practitioners and managers, as it proposes implementation of a knowledge management pilot project in Slovenian public sector.

    Full Text Available In this paper, we shows the contribution of the secondary sector (industry and construction on the economic development of the regions, functional areas and the urban system in Romania. The development of economic activities of production is conditioned by certain geophysical, demographical, social and cultural characteristics. Considering that economic restructuring and privatization of industry put their mark on the evolution of the Romanian economy in recent years, it is absolutely necessary to take into account the influence of the secondary sector activities - industry and construction, to establish the development measures of romanian regions. One more reason is that the most industrialized cities prior 1990, dependent on a single branch of industry, losing the markets for these industries, recorded high unemployment, which in terms of social, equates to a high degree of poverty. Territorial development of the secondary sector shows large differences mainly due to natural barriers, level of accessibility to natural resources and public services of general interest. These gaps deep more economic and social problems existing in the territory. In the secondary sector, Romania follows closely the provisions of European Union policy, in order to develop a national competitive market, integrated into the European internal market. An example: in the industrial branch, employment share is approximately equal to the european average level. In terms of productivity, in Romania, in the context of a very low level of this indicator, its value is high in the industrial sector (especially in the manufacturing sector the specific productivity is above the national average. It is estimated that after 2014, the improvement of Romania's macroeconomic stability could generate rapid growth in the secondary sector. In Romania, industrial sector faces with problems such: the high level of resources not identified, poor promotion on domestic and foreign market

    Full text: Maintenance is a critical issue for fusion DEMO reactor because the design conditions and requirements of DEMO maintenance scheme are different from that of ITER remote handling. The sector transport maintenance scheme has advantages to maintain blankets and divertors without the use of sophisticated remote handling devices including sensitive devices to radiation in the reactor. SlimCS designed in JAEA adopts the sector transport maintenance scheme in which every sector is pulled out horizontally through a port between TF coils. A critical design issue for the horizontal sector transport maintenance scheme is how to support an enormous turnover force of the toroidal field (TF) coils. We propose following two options; first option is the horizontal transport maintenance scheme in which every sector is pulled out through four horizontal ports connected with the corridor. Second option is the vertical sector transport maintenance scheme with small vertical maintenance ports (total: 6 ports). The new horizontal sector transport limited in the number of maintenance ports is a more realistic maintenance scheme, and the key engineering issue is the transferring mechanism of sector in the vacuum vessel. In the maintenance scenario, the key design factors are the cool down time in reactor and the cooling method in maintenance scheme for keeping components under operation temperature. By one-dimensional heat conduction analysis, the sector should be transported to hot cell within 40 hours in the case the cool down time is one month. In the horizontal sector transport maintenance, the maintenance time including removal of cooling piping, drain of cooling water and sector transport to hot cell is about 32 hours. Furthermore, the tritium release in the sector transport can be suppressed because the components temperature drops by forced-air cooling system. This paper mainly focuses on a sector transport maintenance scheme from the aspects of high plant availability

Os dados utilizados no estudo foram obtidos de experimento realizado com 12 vacas Holandês x Gir, multíparas, com produção média de 18,2kg/dia de leite, distribuídas em três quadrados latinos 4 x 4, conforme a produção de leite, a ordem de lactação e o peso corpóreo. As dietas foram isoproteicas, fornecidas ad libitum na forma de mistura total (relação volumoso:concentrado de 60:40, base matéria seca, e os consumos das vacas determinados diariamente. As produções individuais diárias de leite foram registradas, e sua composição foi analisada quanto aos teores de gordura, proteína e ácidos graxos. A viabilidade econômica foi realizada considerando-se os preços dos ingredientes fornecidos e o consumo diário da dieta de cada tratamento. O benefício econômico foi obtido pela diferença entre a receita, com a venda do leite, e o custo com alimentação dos animais. O pagamento por qualidade foi estimado pela média de oito sistemas utilizados por empresas do ramo de laticínios, com base nos teores de gordura, proteína e no volume de leite. A dieta sem inclusão de OG foi a que proporcionou maior benefício econômico. A inclusão de OG nas dietas baseadas em cana-de-açúcar não foi viável, economicamente, devido aos gastos adicionais com OG e às penalizações resultantes da redução dos teores de proteína e de gordura do leite.

  8. (How) does sectoral detail affect the robustness of policy insights from energy system models? The refining sector's example

    2014-01-01

    In this research, we rekindle an old debate by questioning the impact on mitigating policy evaluation of detailing a sub-sector in a global energy-transportation model. We chose the refining sector because it is a relevant case of a sector for which representation widely differs across models and because it offers a unique set of complex joint production in the energy sector. To investigate whether the level of detail in the description of the refinery impacts optimal mitigation options, we take the example of a long-term, national, linear programming based, energy-transport system model (TIMES based). We found that the refinery description used in the energy system model matters when trying to evaluate energy or climate policy applied to the transportation sector. It impacts the policy costs but also the technology trajectories chosen at the optimum. Essentially, the balance between energy efficiency and carbon intensity of transport may be affected by the accuracy of the description of the pivotal refining sector. Consequently, increasing this sector accuracy level should not only be motivated by the wish to gain wider quantitative insights on potential evolution of the energy system but also by the wish to improve the robustness of the model outcomes.

  13. Public and Private Sector IT Governance: Identifying Contextual Differences

    2010-01-01

    Full Text Available This paper highlights systemic contextual differences and the unique IT Governance issues that might arise in public and private sector organizations. Public sector organizations constitute a significant component of economic activity in most countries. Like their private sector counterparts, many public sector agencies are struggling to cope with reduced or inadequate IT budgets and are continuously looking for ways to extract maximum value from IT resources. While both sectors face similar managerial-level IT issues and challenges, we argue that there are systemic differences between private and public sector organizations suggesting that a one size fits all approach to IT Governance may not apply.

  14. Public Sector Wage Growth in Alberta

    2012-01-01

    Full Text Available In recent years, Alberta’s fiscal stance has shifted from large surpluses to deficits, and a large part of the blame appears to be due to rising public sector salaries. Since 2000, the province’s public sector wage bill has shot up by 119 percent — almost double the rate of growth in the rest of Canada. Wages, previously roughly at par with the rest of the country, are now higher (in many cases very substantially across all public sector categories, including health care, social services, education and government, consuming 95 percent of the increase in provincial revenues over the past decade. At the same time, the number of public sector employees has grown faster than the overall population; it is difficult to attribute this sharp uptick to a rise in productivity, or the need to compete with private industry for skilled workers. This paper breaks down the increases in every category, arguing that if the provincial government is looking to trim expenditures, public sector salaries are a good place to start. The authors make their case using detailed Statistics Canada data, throwing down the gauntlet to defenders of the status quo and challenging them to justify these disparate increases.

    The electricity supply sector in Pakistan has performed poorly in recent years. Reforms were introduced in the mid-1990s to improve the sector, but progressed slowly with no significant impacts on pre-reform performance. This study uses new institutional economics as a theoretical basis to elucidate reasons for the failure of power sector reforms in Pakistan to make improvements. Interviews with 23 experts using Q-methodology generated 215 statements that were used as a Q concourse. Of these, 51 statements were selected for the Q sample and ranked by 34 respondents depending on their importance. Analysis revealed four important discourses on the determinants of power sector reform failure in Pakistan. These included weak governance structure, country and sectoral endowments, inefficient regulator and unspecified political institutions or unfriendly political contexts. The study recommends establishment of institutions that support a market based power supply sector and improvements to the contractual arrangements between stakeholders to reduce opportunistic behaviour. - Highlights: • This study utilizes New Institutional Approach to study power sector reforms in Pakistan. • Work of Douglass North and Oliver Williamson help create analytical frame. • Q methodology helps overcome data limitations. • Results reveal institutional aspects as important for poor performance of reforms. • Study suggests policy recommendations to improve institutional environment and governance of power sector in Pakistan.

    Utkarsh Shah, Ragini Mohanty

    2011-01-01

    Full Text Available This research paper attempts to collate literature from various sources, in an attempt to answer three pertinent questions related to healthcare in India. Firstly, what is it meant by ‘private sector’ in healthcare delivery system of India, secondly how has the private sector evolved over the decades and what has been the role of the government in propelling the growth. Finally, the paper tries to highlight some of the factors that have promoted the growth of private sector in India with specific reference to quality of medical care. The paper explicitly indicates that the deficiencies in the public health delivery system of India, was the key to growth of private infrastructure in healthcare.The shift of hospital industry for ‘welfare orientation’ to ‘business orientation’ was marked by the advent of corporate hospitals, supported by various policy level initiatives made by the government. Today, there are over 20 international healthcare brands in India with several corporate hospitals.However, a large section of the ‘private healthcare delivery segment’ is scattered and quality of medical care continues to remain a matter of concern. This paper tracks the various government initiatives to promote private investment in healthcare and attempts to explore the reasons for preference of the private sector. Surprisingly, in contrast to contemporary belief, quality of medical care doesn’t seem to be the leading cause for preference of the private sector. Except for a few select corporate and trust hospitals, quality of medical care in private sector seems to be poor and at times compromised.

    The causes of health inequalities are complex. For the reduction of health inequalities, intersectoral collaboration between the public health sector and both social policy sectors (e.g. youth affairs, education) and physical policy sectors (e.g. housing, spatial planning) is essential, but in local practice difficult to realize. The aim of this study was to examine the collaboration between the sectors in question more closely and to identify opportunities for improvement. A qualitative descriptive analysis of five aspects of collaboration within sixteen Dutch municipalities was performed to examine the collaboration between the public health sector and other policy sectors: 1) involvement of the sectors in the public health policy network, 2) harmonisation of objectives, 3) use of policies by the relevant sectors, 4) formalised collaboration, and 5) previous experience. Empirical data on these collaboration aspects were collected based on document analysis, questionnaires and interviews. The study found that the policy workers of social sectors were more involved in the public health network and more frequently supported the objectives in the field of health inequality reduction. Both social policy sectors and physical policy sectors used policies and activities to reduce health inequalities. More is done to influence the determinants of health inequality through policies aimed at lifestyle and social setting than through policies aimed at socioeconomic factors and the physical environment. Where the physical policy sectors are involved in the public health network, the collaboration follows a very similar pattern as with the social policy sectors. All sectors recognise the importance of good relationships, positive experiences, a common interest in working together and coordinated mechanisms. This study shows that there is scope for improving collaboration in the field of health inequality reduction between the public health sector and both social policy sectors

    2011-04-01

    We describe the pension plan features of the states and the largest cities and counties in the U.S. Unlike in the private sector, defined benefit (DB) pensions are still the norm in the public sector. However, a few jurisdictions have shifted toward defined contribution (DC) plans as their primary savings plan, and fiscal pressures are likely to generate more movement in this direction. Holding fixed a public employee's work and salary history, we show that DB retirement income replacement ratios vary greatly across jurisdictions. This creates large variation in workers' need to save for retirement in other accounts. There is also substantial heterogeneity across jurisdictions in the savings generated in primary DC plans because of differences in the level of mandatory employer and employee contributions. One notable difference between public and private sector DC plans is that public sector primary DC plans are characterized by required employee or employer contributions (or both), whereas private sector plans largely feature voluntary employee contributions that are supplemented by an employer match. We conclude by applying lessons from savings behavior in private sector savings plans to the design of public sector plans.

    Direct wage comparisons show that public-sector 
employees earn around 15% more than private-sector employees. But should these differences be interpreted as a “public-sector premium”? Two points need to be considered. First, the public and private sectors differ in the jobs they offer and the type of workers they employ, which explains a large share of the wage gap. Second, public- and private-sector careers also differ in other important dimensions, such as job stability and income progress...

    In this paper, we analyze differences in per capita carbon dioxide emissions from 1996 to 2010 in six sectors across 28 provinces in China and examine the σ-convergence, stochastic convergence and β-convergence of these emissions. We also investigate the factors that impact the convergence of per capita carbon dioxide emissions in each sector. The results show that per capita carbon dioxide emissions in all sectors converged across provinces from 1996 to 2010. Factors that impact the convergence of per capita carbon dioxide emissions in each sector vary: GDP (gross domestic product) per capita, industrialization process and population density impact convergence in the Industry sector, while GDP per capita and population density impact convergence in the Transportation, Storage, Postal, and Telecommunications Services sector. Aside from GDP per capita and population density, trade openness also impacts convergence in the Wholesale, Retail, Trade, and Catering Service sector. Population density is the only factor that impacts convergence in the Residential Consumption sector. - Highlights: • Analyze differences in CO 2 emissions in six sectors among 28 provinces in China. • Examine the convergence of CO 2 emissions in six sectors. • Investigate factors impact on convergence of CO 2 emissions in each sector. • Factors impact on convergence of per capita CO 2 emissions in each sector vary

    2012-06-01

    Full Text Available The labour legislation applicable in public sector is very different from the one applicable in private sector. Unlike the private sector where the market is the most efficient regulator and sanctions all errors made by the assessor, in the public sector there isn’t always a feed-back from the economic realities that may prove the accuracy and the efficiency of the assessment. Consequently, the law goes further on and imposes requirements, deadlines and procedures. While the private sector enjoys a certain flexibility regarding the assessment of the staff, in order to adjust it to the requirements of the economic realities, in the public sector, flexibility can lead to manifestations of subjectivism and arbitrariness. On the other hand, the excessive amount of regulations applicable in public sector may provide versatile and even contradictory results.

    The paper examines the impacts of financial development on sectoral carbon emissions (CO 2 ) for environmental quality in Malaysia. Since the financial sector is considered as one of the sectors that will contribute to Malaysian economy to become a developed country by 2020, we utilize a cointegration method to investigate how financial development affects sectoral CO 2 emissions. The long-run results reveal that financial development increases CO 2 emissions from the transportation and oil and gas sector and reduces CO 2 emissions from manufacturing and construction sectors. However, the elasticity of financial development is not significant in explaining CO 2 emissions from the agricultural sector. The results for short-run elasticities were also consistent with the long-run results. We conclude that generally, financial development increases CO 2 emissions and reduces environmental quality in Malaysia.

    2011-01-01

    Marine renewable energy is an emergent sector in Canada. Although supply chain studies have been performed on the United Kingdom and the United States markets, no study has been conducted yet in Canada. The aim of this study was therefore to perform a supply chain analysis in Canada to assess the maturity, strengths, and weaknesses of the sector and determine where the opportunities lie. The study emphasises that the sector is still at the prototype stage in Canada and that the industry must learn to improve its technology and begin to take on large scale projects. Canada has several strengths in the marine renewable energy sector, mainly in terms of resources and facilities, but there are also weaknesses pertaining to technology development and experience. The study concluded that the development of the sector must be centered on a solid vision; in the near term, technological innovation is needed to reach pre-commercialization while in the long term, the sector should aim for commercial application.

    1995-01-01

    The current regulatory regime governing the electricity and gas supply industries of the energy sector is characterized by the admissibility of protected sales areas defined by demarcation agreements. However, this economic advantage is counterbalanced by legal provisions providing for specific supervision of the utilities under cartel law. The cartel authority exercises the functions of control of abusive practices, focussing on control of prices and general terms and conditions, cooperation between the utilities and operators owners of power generation plants, the very topical aspects of TPA (third party access to networks), and adherence to the principle of conduct of business of the utilities in line with the conditions of free competition. The book addresses all relevant aspects of cartel control relating to existing law and the overall context of the energy sector. General principles of cartel control in the economic sector at large are compared to specific conditions in the energy sector, revealing the differences in competences of the cartel authority.

    The incident in 3-4 sector has affected some 50 main LHC magnets. Such a scenario was never considered as realistic in the past. Our reserve of magnet has been barely sufficient (some 40 dipoles and 14 SSS, in some cases the reserve magnet types are not compatible with the one damaged). Furthermore the subsequent measurements on other sectors have shown the necessity to replace other magnets. The plan and methods for assessing the damage that occurred to a cold mass and the decision on its substitution, rather than a simple revamping of the magnet itself, will be discussed. The question if the magnets in the sector are adequate for powering and beam operation will be addressed. The implementation of the changes and their traceability will be presented. Finally the spare situation, which includes the plan for repairing and testing of all damaged cold masses of sector 3-4 and the impact on it of the 3-4 incident, is discussed.

    With the increased use of photovoltaic systems in dwellings and other areas, it is important the growing concern in sustainable development, as well as the tax benefits gotten by the acquisition of this type of systems. In this context, technical aspects of trading systems should be considered, as well as characteristics of sunlight, humidity, etc., where the photovoltaic equipment will be installed. This article seeks to increase the efficiency of commercial solar panels from a simple and economical perspective using refraction. Through three different tests, first normal operating conditions and two more tests with different conditions of temperature, humidity and water vapor the authors seek to understand the behavior of electric power generation of the PV system used. With the results obtained in this work set the tone by opening new opportunities to investigate more deeply the thermal and moisture characteristics of solar panels based on their efficiency and materials involved in the design. [Spanish] Con el incremento del uso de instalaciones fotovoltaicas en casas habitacion y en otros ambitos, es importante la creciente concientizacion del desarrollo sustentable, ademas de la utilizacion de los beneficios de impuestos que se tienen al comprar este tipo de sistemas.

    The critical analysis is presented as a synthesis of the problem untied since the implementation of the daylight saving time. The often related history is retaken to introduce the reader into the context of the causes of a such program. The geometric aspect of the solar trajectories is discussed and the length of the day as a function of the latitude and the time of the year to have technical elements for the time displacement in a certain region. The technical implementation of the daylight saving time based on three elements is justified: time of dawn and the decline (length of the day), national economic motivation and tourism industry. Stands out that although the daylight saving time schedule has a set of social and economic benefits it is not centered in the individual but in the society as a whole. The errors in handling the information and the misinformation are pointed out as the main causes of the controversy, the discord and the political manipulation of competing groups. [Spanish] El analisis critico se presenta como una sintesis del problema desatado desde la implementacion del horario de verano. La historia muchas veces contada se retoma para introducir al lector en el contexto de las causas de un tal programa. Se discute el aspecto geometrico de las trayectorias solares y la longitud del dia como una funcion de la latitud y de la epoca del ano para tener elementos tecnicos para el desplazamiento horario en una region determinada. Se justifica la implementacion tecnica del horario de verano en funcion de tres elementos: hora de alba y del ocaso (longitud del dia), motivacion economica nacional e industria turistica. Se destaca que si bien el horario de verano tiene un conjunto de beneficios sociales y economicos no se centra en el individuo sino en la sociedad en su conjunto. Se senalan los errores de manejo de la informacion y la desinformacion como los principales causantes de la polemica, el desacuerdo y la manipulacion politica de grupos

  9. Global Sectoral Industry Approaches to Climate Change. The Way Forward

    International Nuclear Information System (INIS)

    Stigson, B.; Egenhofer, C.; Fujiwara, N.

    2008-01-01

    The structure of some industrial sectors is so highly concentrated that just a handful of companies are responsible for producing a significant share of that sector's total greenhouse gases emissions worldwide. These sectors are thus a 'natural' focus of policy-makers concerned with climate change and have attracted keen interest from the EU. So-called 'sectoral approaches' are seen as having the potential to broaden the range of contributions by all parties, including emerging economies, to greenhouse gas emissions reductions, and to help moderate competitiveness concerns in trade-exposed industries. In particular, such approaches may help to quantify emissions on a sector-by-sector basis, building confidence that policies and measures can be put in place to reduce emissions. They can also help identify national or global commitments through the aggregation of sectoral data. While sectoral approaches allow policy-makers to concentrate on those individual sectors that contribute significantly to global emissions, they also pose a number of challenges. This CEPS Task Force Report identifies the principal issues associated with sectoral approaches - their rationale and the associated political dynamics - and gives an overview of existing approaches, the formulation of preconditions that would allow sectoral approaches to be implemented and an analysis of the potential interaction of sectoral approaches with existing climate change policies. The concluding chapter sketches a possible way forward

    oportunidades para todo el mundo. Acostumbradas al proteccionismo del antiguo modelo de desarrollo, hoy en día las sociedades latinoamericanas perciben la amenaza de un modelo nuevo que no les ofrece ninguna red de protección social. La viabilidad de las políticas de reforma económica y social de las segunda fase, que se ajustan a las exigencias de un mundo "globalizado", depende, entonces, de poder vencer la desconfianza de la población y de lograr el respaldo de una mayoría política, social e institucional.In Latin America, health sector reforms have gone hand in hand with social and economic trends during the latter half of the twentieth century and have reflected the particular concept of "development" that has been in vogue at different times. Economic stagnation and increased social spending, both hallmarks of the 1960s, led to the decline of the "import substitution" development model, which had prevailed since the beginning of the century, and slowly gave way in the 1980s to the "globalization"model. From the earlier model, a transition took place toward a restructuring of production and a series of economic adjustment policies that led, ironically, to an increase in poverty in Latin America. Implementation of the new model has occurred in two phases. The first, known as the "social reform" or "first generation "phase, sprang from the notion that poverty is the sum of a number of material shortages that can be corrected through an equitable redistribution of a fixed volume of goods belonging to society. This conceptual framework, which was completely devoid of all historical linkages and separated from economic policy, led to social policies whose entire purpose was to mitigate poverty through subsidies targeting the poorest persons in the society. In the second phase of the globalization model, which arose in the 1990s and became known as the "second generation" or "postadjustment" phase, new economic rules came into play that were based primarily on

    There is a growing need of evaluating experiences with the liberalization of different sectors in the Netherlands. To what extent do the technical, economical and organizational characteristics of a sector determine the options to deal with competition? And to what extent does the type of competition determine whether the aimed for improvement of the efficiency and effectiveness of the service will be realized or not? Thereto, a systematic comparative analysis of infrastructure-related sectors has been carried out. In this report the experiences of the liberalization process in the electric and gas utilities sectors and the public transportation (buses and railway) sector are translated to preliminary conclusions and new research questions with respect to the possibilities to introduce competition in the water supply sector. refs

  18. General overview of the Mexican energy sector

    Perez-Jacome, D.

    1999-01-01

    An overview of Mexico's energy sector was presented, with particular focus on the natural gas and electricity sectors. Mexico ranks fifth in oil production, eighth in proven oil reserves, and fourteenth in natural gas reserves. In 1998, the energy sector generated 3.3 per cent of Mexico's gross domestic product (GDP), and oil accounted for 7.5 per cent of total exports. National production of natural gas has been forecasted to grow at a rate of 5.2 per cent annually over the next 10 years. This will be largely due to the increased demand for natural gas to produce electricity. The Mexican government has also taken initiatives to restructure the Mexican energy sector with particular focus on increasing the competitiveness of the electric power industry. Electricity demand is also expected to grow at a rate of 6 per cent annually over the next six years. The objectives of energy reform are to promote more investment from all sectors in order to strengthen the development of the electric power industry and to provide a reliable, high quality service at competitive prices. 9 figs

    Since Pigou proposed that the internalization of the negative externalities could be done calculating a tax in order to correct the difference between private costs and social costs; this will recover the conditions of economic efficiency in all the hydraulic legislations of the world, however, this advice has been applied in conditions of great shortage; it could be thought that to burden the consumptive use could be more suitable than to burden the production of residual water reaching this way not only the recovering of social efficiency but also a double dividend: to stimulate the water recycling. This work evaluates the effect that the tax to the consumptive use will have over a fake economy. The achieved results are compared using data from two economies with a different water production each one. The contrast is done using a model of computable general equilibrium with the Arrow-Debreu assumptions relaxed with the introduction of a government that collect the proposed taxes in a previously distorted economy. The collection distributes through a direct transference to the revenue of the consumers, the model calibrates and resolves following the methodology proposed by Shoven and Whalley (1984). [Spanish] Desde que Pigou propuso que la internalizacion de las externalidades negativas podria hacerse a traves de un impuesto que corrigiera la diferencia entre costos privados y costos sociales -de forma tal que se recuperaran las condiciones de eficiencia economica-, practicamente en todas las legislaciones hidraulicas del mundo se ha aplicado esta recomendacion; sin embargo, en condiciones de gran escasez de agua podria pensarse que gravar la cantidad de agua incorporada definitivamente al producto final, el uso consuntivo, podria ser mas adecuado que gravar la produccion de agua residual, pues asi se lograria, ademas de recuperar las condiciones de eficiencia social, un doble dividendo: incentivar el reciclaje del agua.

    This paper explores the apparent paradox that while public sector auditors have become more powerful by claiming performance auditing expertise and linking this to New Public Management reforms, the same reforms have provided an opening for competition between private and public sector auditors....... In Denmark, the competitive relation has led to a jurisdictional dispute between public and private sector auditors in which the former have developed a special qualification for public sector auditors. The paper analyses the development of this qualification using Abbott's (1988) theory of the system...... of professions, thus focusing on how the involved groups have attempted to build networks of support for their competing jurisdictional claims of expertise. The case contributes to knowledge about the potential for development of a distinct public sector auditor identity. The case suggests that to develop...

    2004-06-01

    The University-External Sector vinculation is an increasing phenomenon in Latin America as in the rest of the world. The universities through its investigation processes actively participate in the creation and incorporation of science and technology to produce technological processes, to bring foreign technology into national reality, and also to create and transmit innovation for the productive sector. In those ways these institutions achieve bonds with the external sector which provide them with additional income and allows them to have certain relief for their tight teaching and investigation budgets. Several studies in university organizations have been made to identify the motivations and barriers for de adequate development of the interaction between the university and the external sector. The lack of vinculation between these institutions could be due in part to the lack of knowledge that the external sector has of the possibility to obtain services from the university, and also the lack of knowledge that the university has about the needs of potential users of their services. The goals achieved by public Venezuelan universities, in the last years, in their search of a vinculation with the external sector could grow and consolidate through an adequate strategic management plan that allows a mayor diffusion and promotion of the results of their investigations and services, to reach in a wider and more direct way, and to a greater number of potential clients.

    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.

    Employing approximately 1.5 million employees and comprised of 80,000 employers, the retail and wholesale sector accounted for 16.1% of South Africa's gross domestic product in 1996. HIV/AIDS threatens the retail sector, but it is unclear whether the pandemic threatens equally every sub-sector of the industry. The 4 main sub-sectors are fast-moving consumer goods; clothing, footwear, and textiles; vehicles; and furniture and major appliances. The nature of retail infrastructure and competitive and economic trends are described. Over the next decade, AIDS may reduce the size of consumer markets through increased mortality, and will certainly slow growth in spending. The pandemic may also divert spending away from retail merchandise to health care, and threaten businesses which extend credit and offer death benefits and funeral policies to clients. AIDS morbidity and mortality could also disrupt supply chains, especially for retailers who buy their products locally. The vulnerability of retail activities is discussed, with reference to the Living Standards Measure (LSM) developed by the South African Advertising Research Foundation.

    2016-07-01

    Full Text Available Electrical energy is as one of the important effective factors on economic growth and development. In recent decades, numerous studies in different countries to estimate and forecast electricity demand in different parts of the economy have been made. In this paper, using the method ARDL, estimation and forecasting of electricity demand in the services sector of Iran are determined for the time period from 1983 to 2012. Estimated equations show that the added value of the services sector and a significant positive impact on the demand for electricity in this sector. The price elasticity for services sector is smaller than 1 due to low electricity prices and subsidized electricity. Hence, electricity prices have little impact on the demand for electricity. The results of the estimate represents a long-term relationship between the variables in the services sector. In this paper, based on amendments to the law on subsidies and estimated values, anticipated electricity demand until the end of the fifth development plan was carried out. The results indicate an increase in power consumption in the services sector.

    Traditional capacity-building approaches tend to be organizationally focused ignoring the fact that community-based organizations learn and take action in a larger network working to promote positive community change. The specific aim of this paper was to outline a vision for a Third Sector Alliance to build organizational, network, and sector capacity for community well-being in Miami. Building a foundation for social impact requires a strategy for organizational, network, and sector capacity building. Organizational, network, and sector capacity building can best be achieved through a cooperative network approach driven by a solid community-university partnership. Although a Third Sector Alliance for Community Well-being does not yet exist in Miami, Catalyst Miami and the University of Miami (UM) have partnered closely to articulate a vision of what could be and have been working to make that vision a reality.

    A small proportion of physicians adhere to tuberculosis (TB) notification regulations, particularly in the private sector. In most developing countries, the private sector has dominance over delivering services in big cities. In such circumstances deviation from the TB treatment protocol is frequently happening. This study sought to estimate TB notification in the private sector and settle on determinants of TB notification by private sector physicians. A population-based study has been conducted; private physicians at their clinics were interviewed. The total number of 443 private sectors' physicians has been chosen by the stratified random sampling method. Appropriate descriptive analysis was used to describe the study's participants. Logistic regression was used for bivariable and multivariable analysis. The response rate of the study was 90.06 (399%). Among responders, who had stated that they were suspicious of TB over the recent year, 62 (16.45%) stated that they reported cases of TB at least once during the same period. Having reporting requirements and the number of visited patients was significantly related to TB suspicious (odds ratio = 2.84, confidence interval: 1.62-5, P private sector by simple and quick interventions. It seems that a considerable fraction of private sector physicians, not all of them, will notify TB if they are provided with primary information and primary resources. To optimize the TB notification, however, intersectoral interventions are more likely to be successful.

    Full Text Available The article studies the development of the Far Eastern bioresource sector in 2006–2015 and its components: fishing industry, forestry and agriculture. It is shown that renewable bioresources, which form the foundation of the bioresource sector, are now becoming the limiting factor of that sector’s further extensive development which necessitates a transition to new ways and technologies of extracting and processing resources. The article attempts to identify and estimate the bioresource sector’s contribution to the economy of the Far Eastern Federal District (FEFD as a statistical unit through aggregating main macroeconomic indicators (gross added value, monetary value of exports, investments, number of employed, and tax revenue of its three components. The conclusion is that during the studied period the bioresource sector’s contribution to the economy of the FEFD has decreased mainly due to the factors of tax revenues and gross added value. The sector’s importance as source of employment in remote areas had also declined. At the same time the bioresource sector continues to significantly contribute to exports, mainly thanks to the fishing industry and agriculture. It is shown that the dominant role in the bioresource sector belongs to the fishing industry which increased its contribution to the bioresource sector and showed the most stable development compared to other components. The article studies changes in institutional conditions in all three components, their influence on the development of investments of the bioresource sector

    2008-01-01

    During the past decades, the traditional state monopoly in urban water management has been debated heavily, resulting in different forms and degrees of private sector involvement across the globe. Since the 1990s, China has also started experiments with new modes of urban water service management and governance in which the private sector is involved. It is premature to conclude whether the various forms of private sector involvement will successfully overcome the major problems (capital shortage, inefficient operation, and service quality) in China’s water sector. But at the same time, private sector involvement in water provisioning and waste water treatments seems to have become mainstream in transitional China. PMID:18256780

    The effects of a world oil price shock on U.S. agriculture are analyzed in an economywide environment. The authors use an input-output model to analyze the direct and indirect cost linkages between energy and other sectors of the economy. Then, to allow sectoral output adjustment and the effects on the U.S. current account, they use the U.S. Department of Agriculture/Economic Research Service Computable General Equilibrium (CGE) model to analyze the sectoral effects under three different macro adjustment scenarios. The effects on agriculture are not limited to the direct and indirect energy costs. Exchange rate or foreign borrowing adjustments to higher oil import costs and government support programs for agriculture also matter

    2017-01-01

    Nuclear industry is the 3. industrial sector in France and is the good reason why the French energy mix is largely carbon-free. The medium term challenges that faces nuclear industry in this country is first to succeed the extensive refit of nuclear power plants with a view on getting the extension of their operating life and secondly to recruit the skilled staff nuclear industry needs. About 8000 jobs dispatched in the 2500 enterprises that forms the nuclear sector will be available each year up to 2020. The age pyramid shows that numerous retirements are expected in the years to come so the issue of skill and knowledge transfer is looming. 25% of recruitment will be made on the basis of work-study contracts particularly for technical jobs. Concerning recruitment, the nuclear sector is competing with other high-tech sectors like aeronautics or the automobile sector, which make things harder. The image that nuclear industry wants to promote of itself is the image of a young, modern, high-tech industry that appeared less than 50 years ago and whose main purpose is to provide a carbon-free electricity to an avid world.

    Full Text Available The viability and infectivity of an ectomycorrhizal inoculum (isolate UFSC-Rh90, Rhizopogon nigrescens, produced by submerged cultivation in an airlift bioreactor and immobilized in beads of calcium alginate gel, was studied. Inoculum remained 100% viable after 18 months in a 0.85% NaCl solution at 8 ± 1ºC. Mycelium grew from the beads after 48 h when they were placed on a solid culture medium at 25 ± 1ºC. Viability of pellets of non-immobilized mycelium stored under the same conditions decreased gradually after the third month of storage, reaching 0% by the 12th month. These pellets presented a gradual darkening, which was more intense in those located near the surface of the NaCl solution. In culture medium, these dark pellets showed no viability. Gel immobilization helps to maintain mycelium viability during storage and offers a physical protection when the inoculum is applied to the planting substrate. After eight months refrigeration, the immobilized inoculum was still able to infect Pinus taeda seedlings, colonizing an average of 37% of the root tips when inoculated in the plant growth substrate under greenhouse conditions. This inoculum presents a commercial potential to be produced and applied in forest nurseries.Estudou-se a viabilidade e a infectividade de inoculante fúngico ectomicorrízico (isolado UFSC-Rh90, Rhizopogon nigrescens, produzido através de cultivo submerso em biorreator airlift e encapsulado em gel de alginato de cálcio. O inoculante permaneceu viável após 18 meses em solução de NaCl (0,85% a 8 ± 1ºC. O micélio emergiu dessas cápsulas após 48 h de incubação a 25 ± 1ºC em meio de cultura sólido. A viabilidade dos pellets de micélio não imobilizado, armazenados sob as mesmas condições, reduziu-se gradualmente após três meses de armazenamento e atingiu 0% aos 12 meses. Esses pellets apresentaram um escurecimento gradual que foi mais intenso naqueles localizados próximos à superfície da solu

    SUMMARYThis article presents an analysis of public sector employment (PSE) and makes comparisons with the private sector, using data from the Labour Force Survey and Annual Survey of Hours and Earnings. It looks at the nature of employment in the public sector before discussing the characteristics that differentiate people employed in both the public and private sector, comparing proportions of public and private sector workers in different groups: by sex, age, ethnicity, disability, working ...

    that the ruling elite initially supported the fishing industry because of industry pressure. They have failed to enforce fisheries management because there are big political costs associated with such enforcement. The dairy sector in the southwestern milk region was initially supported because the ruling elite......This paper explains the differences in ruling elite support for the fisheries and dairy sectors in Uganda. Although production in Uganda has not generally been promoted in any sustained way, ruling elites have to varying degrees supported the dairy and fisheries sectors. The paper shows...... wanted to build a coalition of support in this region. Coming from the region himself, the president had a keen interest in dairy cattle. The sector was subsequently regulated because the biggest processor put pressure on the ruling elite to do so. Even when the ruling coalition is fragmented, promoting...

    Strategic concepts and practices first evolved in the private sector, so they evoked much controversy when they migrated to the public sector from the late 1970s onwards. Partly this was about their (in)applicability to the distinctive features of government organizations, in particular their focus...... on public as well as private value, their situation in a political rather than a market environment, their almost exclusive capacity to use legal authority to achieve purposes, and the extent to which they often need to share power over personnel and resources with other public sector agencies....... These and other factors complicated efforts to apply New Public Management and similar frameworks in strategy concepts in a governmental context. Partly also the traditional private-sector focus on single organizations did not resonate with the growth of network governance from the 1990s. The authors argue...

  18. Lifshitz-sector mediated SUSY breaking

    We propose a novel mechanism of SUSY breaking by coupling a Lorentz-invariant supersymmetric matter sector to non-supersymmetric gravitational interactions with Lifshitz scaling. The improved UV properties of Lifshitz propagators moderate the otherwise uncontrollable ultraviolet divergences induced by gravitational loops. This ensures that both the amount of induced Lorentz violation and SUSY breaking in the matter sector are controlled by Λ HL 2 /M P 2 , the ratio of the Hořava-Lifshitz cross-over scale Λ HL to the Planck scale M P . This ratio can be kept very small, providing a novel way of explicitly breaking supersymmetry without reintroducing fine-tuning. We illustrate our idea by considering a model of scalar gravity with Hořava-Lifshitz scaling coupled to a supersymmetric Wess-Zumino matter sector, in which we compute the two-loop SUSY breaking corrections to the masses of the light scalars due to the gravitational interactions and the heavy fields

  19. Regulation of the power sector

    CERN Document Server

    2013-01-01

    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

  20. The gas sector in Quebec

    Natural gas in Canada represents 29% of the primary energy and 42% of the energy used in the industrial sector. The biggest users are the manufacturing industries for which the low cost of natural gas and the quality of products resulting from its use represent a serious advantage in a more and more competitive market. This document takes stock of the situation of natural gas and gas-related technologies in Quebec. The first part recalls the historical evolution of the gas distribution network in Quebec and its present day situation. Then, some technical-economical data about the consumption of natural gas in Quebec are presented according to the sectors of use. The third part treats of the R and D activities linked with the gas sector, in particular the activities of the two main research organizations: the technical centre of natural gas and the research group in gas technologies of the Polytechnique school of Montreal.
