Political institutions and policy outcomes : effects of presidential vetoes on budget making

The article examines how the power distribution between the executive and the legislature under the Presidential system affects policy outcomes. We focus in particular on the presidential veto, both package and partial. Using a simple game theory model, we show that the presidential partial veto generally yields a result in favor of the President, but that such effects vary depending on the reversion points of the package veto and the Congress's possible use of sanctions against the President. The effects of the Presidential partial veto diminish if the reversion point meets certain conditions, or if the Congress has no power to impose sufficient sanctions on the President when the President revises the outcome ex-post. To clarify and explain the model, we present the case of budget making in the Philippines between 1994 and 2008. In the Philippines, the presidential partial veto has been bringing expenditure programs closer to the President's ideal point within what may be called the Congress's indifference curve. The Congress, however, has not always passed budget bills and from time to time has carried over the previous year's budget, in years when the budget deficit increased. This is the situation that the policy makers cannot retrieve from the reversion point.

Nanoinformatics: a new area of research in nanomedicine

Over a decade ago, nanotechnologists began research on applications of nanomaterials for medicine. This research has revealed a wide range of different challenges, as well as many opportunities. Some of these challenges are strongly related to informatics issues, dealing, for instance, with the management and integration of heterogeneous information, defining nomenclatures, taxonomies and classifications for various types of nanomaterials, and research on new modeling and simulation techniques for nanoparticles. Nanoinformatics has recently emerged in the USA and Europe to address these issues. In this paper, we present a review of nanoinformatics, describing its origins, the problems it addresses, areas of interest, and examples of current research initiatives and informatics resources. We suggest that nanoinformatics could accelerate research and development in nanomedicine, as has occurred in the past in other fields. For instance, biomedical informatics served as a fundamental catalyst for the Human Genome Project, and other genomic and ?omics projects, as well as the translational efforts that link resulting molecular-level research to clinical problems and findings.

Reliability and quality in the area of statistical thinking in Engineering

There is remarkable growing concern about the quality control at the time, which has led to the search for methods capable of addressing effectively the reliability analysis as part of the Statistic. Managers, researchers and Engineers must understand that 'statistical thinking' is not just a set of statistical tools. They should start considering 'statistical thinking' from a 'system', which means, developing systems that meet specific statistical tools and other methodologies for an activity. The aim of this article is to encourage them (engineers, researchers and managers) to develop a new way of thinking.

The Role of Multilateral Coordination in Transport Policy: The Case of the Maghreb Countries

El WCTR es un congreso de reconocido prestigio internacional en el ámbito de la investigación del transporte y aunque las actas publicadas están en formato digital y sin ISSN ni ISBN, lo consideramos lo suficientemente importante como para que se considere en los indicadores. This paper aims at describing how multilateral cooperation policies are influencing national transport policies in developing countries. It considers the evolution of national transport policies and institutional frameworks in Algeria, Morocco and Tunisia in the last 10 years, and analyses the influence that EU cooperation programmes (particularly those within the Euromed programme initiative) and international coordination activities have played in the evolution towards efficient, sustainable transport systems in those countries. Notwithstanding the significant socioeconomic, political and institutional differences among the three countries, three major traits are common to the transport policy framework in all cases: a focus on megaprojects; substitution of traditional ministerial services by ad hoc public agencies to develop those megaprojects, and progressive involvement of international private players for the operation (and eventually the design and construction) of new projects, focusing on know-how transfer rather than investment needs. The hypotheses is that these similarities are largely due to the influence of the international cooperation promoted by the European Union since the mid- 1990s. The new decision making situation is characterized by the involvement of two new relevant stakeholders, the EU and a limited number of global transport operators. The hierarchical governance model evolves towards more complex structures, which explain the three common traits mentioned above. International coordination has been crucial for developing national transport visions, which are coherent with a regional, transnational system.

Planeamiento y políticas de vivienda en el área metropolitana de Madrid durante la democracia (1975-2007)

La tesis analiza la realidad residencial construida en los municipios del Área Metropolitana de Madrid durante la democracia, en términos de localización, cantidad y calidad/cualidad, y su relación con el desarrollo de las políticas de planeamiento y de vivienda. La pregunta central que ha guiado la investigación es la siguiente: ¿cómo han incidido los instrumentos de política de vivienda y de planeamiento urbanístico en el crecimiento residencial de los municipios del Área Metropolitana de Madrid? Se trata de poner en relación dos políticas públicas orientadas por la Administración en sus distintos niveles de actuación: una de carácter territorial, el planeamiento urbanístico -cuya ejecución es de competencia municipal-, y otra de carácter sectorial, las políticas de vivienda -definidas por la Administración Central y Autonómica-. Al considerar la política de vivienda como el resultado de la política financiera, la política fiscal y la política de suelo, se ha observado cómo en España las dos primeras suponen más del 70% de la intervención presupuestaria en vivienda. Esta investigación se ha centrado particularmente en la tercera, la política de suelo, por su vinculación directa con el planeamiento urbanístico, pero sin dejar de tener en cuenta las dos primeras, no sólo por su implicación en el gasto público, sino porque han tenido tanto efecto, o más, en la conformación de la ciudad como ha podido tenerlo el planeamiento. La primera parte de la tesis se centra en el estudio de las políticas, sus objetivos e instrumentos (normativos y de planificación), mientras que en la segunda parte se analiza la realidad construida, por medio de una serie de variables e indicadores relacionados con la producción residencial (suelo y viviendas); en la tercera se presenta la parte de análisis y las conclusiones generales. Al cruzar los objetivos y los instrumentos de ambas políticas se ha podido concluir con una propuesta de periodización evidenciando las ontinuidades, cambios o transformaciones: después de una etapa de transición –de 1975 a 1978, coincide con los años de la transición democrática, en el que se definen las bases de las nuevas políticas-, se han podido diferenciar tres períodos: 1979-1989, 1990-1997 y 1998-2007. El primer período corresponde a los años en los que se fue construyendo todo el aparato institucional regulador con las nuevas administraciones que surgieron de la democracia. El segundo período, aunque comenzó con la aprobación de la Ley del Suelo de 1990 como instrumento clave del planeamiento regulador, se caracterizó por el cuestionamiento del modelo intervencionista y por los primeros planteamientos de liberalización. Finalmente, en el tercer período se pusieron las bases normativas de la liberalización del suelo en España, con la reforma de la Ley del Suelo de 1998 y otras medidas “remediales”. Finalmente, se presenta el análisis de los resultados sobre la realidad construida, teniendo como clave de interpretación la periodización propuesta a partir de las políticas, con el propósito de conocer cómo han podido incidir en el crecimiento residencial del AMM. Por tanto, la tesis aborda la inquietud de cuándo, cómo y dónde las políticas públicas han construido ciudad y han generado barrios, pues también trata de analizar los espacios urbanos que han sido el resultado físico de dichas políticas (aspectos de los conjuntos residenciales, el entorno inmediato y su relación con el tejido urbano existente), y no sólo de mostrar cantidades de viviendas construidas. Posteriormente, el estudio se centra en el análisis de las actuaciones públicas sobre suelos destinados a uno de los llamados “usos débiles”, las viviendas protegidas. Éstas se han beneficiado, de una u otra manera, de las ayudas económicas que se incluyen en los planes de vivienda y, por ello, están sujetas a unos parámetros definidos por la normativa vigente en cada caso. Ha interesado realizar una valoración de las mismas a partir de criterios de integración social y funcional, y de equilibrio territorial. ABSTRACT The PhD thesis analyses the residential areas built in the Metropolitan Area of Madrid, in terms of location, quality and quantity, and the relationship to the resulting built environment planning and housing policies. Its cover a period of tree decades since the onset of democracy in Spain in 1975 up to the beginning of the great recession starting 2007. The central question that has guided the research is the following: how the instruments of housing policy and urban planning have influenced the residential growth of the municipalities of the Metropolitan Area of Madrid? It is about putting together two different public policies that are also carried out at different levels of government: spacial and urban planning –whose execution is under municipal jurisdiction under principles and guidelines defined at a regional scale; and the sectorial housing policies which are mostly defined by the Nacional and Regional governments and are very interlinked with the wider economic policies of the country. When considering housing policy as the result of financial, fiscal and land policy, it has been noted in Spain that instruments under the first two types of measures (financial and fiscal) account for over 70% of the housing budget intervention. This research has particularly focused on the third, Land Policy, because of its direct link to urban planning. Nevertheless, the research also considers f inancial and f iscal pol icies, not only because of thei r signi f icant level of publ ic spending, but al so because of thei r great impacto n shaping the way the ci ty is bui l t . The first part of the thesis focuses on the study of the policies, objectives and instruments (housing and planning), while the second part analyses the built reality by means of a number of variables and indicators related to the housing production (land and housing). In the third part the analysis and general conclusions are presented. After relating the objectives and instruments of both policies, the thesis concludes with a proposal for periodization showing continuities, changes and transformations: after a transition period – from 1975 to 1978 coinciding with the years of the democratic transition, in which the basis of the new policies were defined- tree periods (1979-1989, 1990- 1997 and 1998-2007) have been d i s t i n g u i s h e d . The first period covers the years in which a new institutional apparatus wa s b u i l t wi t h t h e n e w a r r a n g eme n t s t h a t eme r g e d from democracy. The second period, even though it began with the approval of the Land Act 1990 as key element of the regulatory planning, was characterized by the questioning of public intervention and early approaches to liberalization. Finally, in the third period, the normative basis of liberalization was set up in Spain, with the reform of the Land Act 1998 and other “corrective” measures. At a final point, the analisys of the results on the reality constructed is presented having as a key of interpretation the periodization proposed. This provides tools for interpreting how policies did affect residential growth in the Metropolitan Area of Madrid. Therefore, the thesis addresses the issues of when, how and where public policies have inf luenced and guided the development of resident ial áreas in the región dur ing this t ime f rame. I t is also concerned with analysing those urban spaces that have been the physical result of such policies (aspects of residential complexes, the immediate environment and its relationship with the existing urban infraestructure), going beyond the analisys of statistical data. Subsequently, the study focuses on the analysis of public actions on land for the so-called "weak uses" particularly social housing. These have benefited in one way or another, of financial assistance included in housing plans and, therefore, are subject to some parameters defined by the regulations in force in each case.

Biomass and essential oil yields of cornmint (Mentha arvensis L.) grown in the irrigation area of Río Dulce, Santiago del Estero, Argentina.

The aim of this study is to determine the yield and composition of the essential oil of cornmint (Mentha arvensis L.) grown in the irrigation area of Santiago del Estero, Argentina. Field tests were carried out under irrigation conditions, harvesting when 70% flowering was reached (in the summer and at the end of the winter seasons). Essential oil yields were 2% in the first cut and 1.6% in the second cut, respectively, the major constituents of the essential oil being menthol, menthone, isomenthone and menthofuran. In both cases, a high concentration of menthol was obtained, although during the winter the content decreased, increasing the concentration of menthofuran. It is concluded that during the summer a higher yield and better quality of essential oil are produced.
