Estilo de desarrollo y el tratado de libre comercio entre República Dominicana, Centroamérica y Estados Unidos. Análisis del capítulo ambiental

Este estilo de desarrollo del país no ha generado encadenamientos productivos y recurre constantemente, a políticas implementadas en la promoción de las exportaciones, liberalización y apertura comercial, drásticos ajustes en las funciones del Estado y la atracción de inversión extranjera (tanto directa como financiera). Objetivos que se materializan en la negociación de tratados de libre comercio al estilo del Tratado de Libre Comercio entre Centroamérica y Estados Unidos. En él se sientan las bases institucionales para la flexibilización del accionar del capital global, la profundización del proceso de apropiación de los factores de producción (básicamente, los recursos y servicios naturales, y la fuerza de trabajo) e incorporar nuevos negocios en sectores que, precisamente, suponen las mejores posibilidades de incrementar la acumulación de capital, siendo éstos, hoy, los recursos energéticos y hídricos. Abstract This style of development of the country has not generated productive linkages and it constantly appeals, to politicians implemented in the promotion of the exports, liberalization and opening commercial, drastic adjustments in the functions of the State and the attraction of foreign investment (so much direct as financial). Objectives that are materialized in the negotiation of treaties of free trade to the style of the Treaty of Free Trade between Central America and United States. In him they feel the institutional bases for the flexibility of working of the global capital, the to make deeper of the process of appropriation of the production factors (basically, the resources and natural services, and the work force) and to incorporate new business in sectors that, in fact, they suppose the best possibilities to increase the capital accumulation, being these, today, the energy and hydric resources.

Acessibilidade no ambiente escolar: reflexões com base no estudo de duas escolas municipais de Natal-RN

This work was originated through the results of the analysis of the services for the needs of people with disabilities that were permitted by the physical space of two schools of the municipality of Natal/RN. The general objective/goal was to subsidize the elaboration of alternatives for the planning of environments that could be used by any person. The study used the empirical research through the adoption of a multimethod approach including: (i) technical visits oriented by the NBR 9050, (ii) contact with users that have reduced mobility (visually impaired and wheelchair or crutch users) through escorted travels and interviews, and (iii) interview with school managers. The evidence from the research, even though with significant development of laws that guarantee people with disabilities their right to citizenship, the physical environment of our schools still present with many obstacles that prevent the mobility of people with disabilities which proves their lack of readiness to accommodate them. Therefore, the actions taken to address the accessibility has been the adoption of temporary solutions that makes the adaptation more difficult, adds obstacles and reinforces the undesirable segregation, however still very present in our society. Finally, there is the indication that in order to achieve the spatial configuration that promotes social contact and integration in between the persons with different physical status, it is necessary to completely comprehend the activities developed in each space, from the conception of the equipment to the individual learning needs, having in mind creating environments that stimulates the execution of the tasks in an independent manner without the assistance of others. The inclusion regarding attention to accessibility in the decision making process, directed to the arquitectural and urban project, would decrease the constant need to redevelop and adapt spaces, and should be definitely incorporated as an important component in the production of space

Coleman’s third report

The article analyses the (third) Coleman Report on private and public schools. The report scrutinises the relationship between private and public schools and shows that private school students show better academic achievement. Coleman concluded that these findings provided a strong argument in favour of public financial support for private schools. However, he identified a number of school characteristics that he believed to be related to student achievement. According to his analysis, these characteristics were not limited to private schools; public schools exhibiting the same characteristics also had good results. Coleman interpreted the available data in favour of financial aid to private schools, although this was not the only possible interpretation. An alternative conclusion would have been to encourage these characteristics in public schools. Why did Coleman disregard this possibility? Why did he deviate from his usual scientific rigour? The present article suggests that there appear to be two reasons for the narrow interpretation of the relationship between public and private schools in Coleman's third report. The first lies in Coleman's notion of contemporary society as a constructed system in which every individual actor holds a place in the structure and requires incentives in order to act to the benefit of society. In the case of education, the goal of the institution is to ensure the high cognitive achievement of students, and the incentive is related to choice and competition. The second reason is related to Coleman's vision of sociology as a discipline aiding the construction of an effective society. (DIPF/Orig.)

International audience

Ernest Mercier, le pétrole et la France

Ernest Mercier est l’un des patrons les plus influents de l'entre-deux-guerres en France. Ses différentes activités industrielles l'ont conduit à siéger sur de vastes pans de l’économie française, notamment du secteur énergétique. La thèse retrace la carrière pétrolière d'un homme qui a joué un rôle central pour le développement d'une industrie devenue stratégique, mais qui est embryonnaire lorsqu'il rejoint ce secteur après la Première Guerre mondiale. Mercier assiste et assure la création d'une industrie pétrolière nationale. Les obstacles se font légion contre les ambitions pétrolières de la France. Elle se présente bien tard sur un marché étroitement contrôlé par de puissants trusts. La recherche et l'exploitation pétrolière demandent d'importantes ressources, et aucune société française n'a les moyens d'une politique indépendante. Certaines banques se lancent alors dans les affaires de pétrole en s'alliant aux grands trusts internationaux. C'est le cas de Paribas; la gestion de ses avoirs roumains représente la première expérience de Mercier dans ce secteur. L'État s'intéresse aussi au pétrole, il devient un acteur incontournable. Le gouvernement français n'a pourtant pas les moyens de ses ambitions dans le domaine pétrolier. La politique nationale mise en place durant l'entre-deux-guerres doit faire appel à l'épargne privée française. La création d'une compagnie nationale, la Compagnie française des pétroles, en 1924 regroupe ainsi les différentes banques et sociétés intéressées au pétrole. Mercier est personnellement choisi par le président Raymond Poincaré pour mener à bien cette mission. Cette carrière s'articule donc autour d'un fragile équilibre entre milieux privés et gouvernement. Mercier devient rapidement l'intermédiaire incontournable qui régit ces relations. La thèse s'appuie sur les archives bancaires et industrielles, mais aussi sur celles du gouvernement français et de ses différents ministères. Cette analyse de la carrière d'Ernest Mercier permet de retracer les origines du secteur pétrolier français et l'action déterminante d'un homme. Elle expose les mécanismes d'influence d'une puissante banque d'affaires et les conflits d'intérêts qu'engendre l'exploitation pétrolière.

Standardized environmental management systems as an internal management tool

In a principal-agent model we analyze the firm’s decision to adopt an informal or a standardized Environmental Management System (EMS). Our results are consistent with empirical evidence in several respects. A standardized EMS increases the internal control at the cost of introducing some degree of rigidity that entails an endogenous setup cost. Standardized systems are more prone to be adopted by big and well established firms and under tougher environmental policies. Firms with standardized EMS tend to devote more effort to abatement although this effort results in lower pollution only if public incentives are strong enough, suggesting a complementarity relationship between standardized EMS and public policies. Emission charges have both a marginal effect on abatement and a qualitative effect on the adoption decision that may induce a conflict between private and public interests. As a result of the combination of these two effects it can be optimal for the government to distort the tax in a specific way in order to push the firm to choose the socially optimal EMS. The introduction of standardized systems can result in win-win situations where firms, society and the environment get better off.

Segurança pública e privada

A presente investigação teve como objetivo analisar o carácter subsidiário e complementar dos serviços de segurança privada, face à atividade desenvolvida pelas forças e serviços de segurança. Centrada nos espetáculos desportivos, procurou mostrar de que forma se materializa a complementaridade e subsidiariedade entre serviços de segurança privada e as forças e serviços de segurança. Através de uma estratégia de investigação qualitativa, concretizada a partir de uma pesquisa documental e um inquérito por entrevista semiestruturada, cujos dados foram alvo de análise de conteúdo, pretendeu-se recolher informação que permita à GNR melhorar a sua atuação na segurança dos espetáculos desportivos. No âmbito da segurança interna, a segurança privada assume um papel fundamental no garante da segurança, a par das atividades desenvolvidas pelas forças e serviços de segurança. Nos espetáculos desportivos, esta relação simbiótica é evidente, sendo um claro exemplo de uma abordagem integrada a este direito fundamental. Conclui-se que a relação, prevista legalmente como complementar e subsidiária, entre serviços de segurança privada e forças e serviços de segurança, se materializa pela adoção e normalização de diversos mecanismos de coordenação e articulação, mas principalmente pela partilha de um fim último comum: a segurança de todos os cidadãos. Abstract: Inserted in the CEMC 2015-16, this work aims to analyze the alternative and complementary nature of private security services, due to the activity carried out by Police Forces. Focusing on sports events, this research sought to show how materializes complementarity and subsidiarity between private security services and Police forces. Through a qualitative research strategy, implemented from documental research and a survey by semi-structured interviews, whose data were subjected to content analysis, we intended to collect information to the GNR improve their performance in the safety of sports events. In the context of internal security, private agents play a key role in security guarantees, along with the activities carried out by security forces and services. In sports events, this symbiotic relationship is too obvious, being a clear example of an integrated approach to this fundamental right. It was concluded that the relationship provided legally as complementary and subsidiarity between private security companies and security forces and services, materializes the adoption and standardization of various mechanisms for coordination and articulation, but mostly by sharing an end last common: the safety of all citizens.

Internationalization process of TUBOFURO

The central objective of this case study was to formulate the strategy of internationalization of Tubofuro®, discriminating relevant points from its design to its implementation. This is a company located in Leiria, Ortigosa parish, which operates, among others, in the Portuguese PVC pipes industry for which currently the domestic market is clearly insufficient, given the oversupply compared to demand. Being Tubofuro® an exporting company since 2004, the work here developed specifically intended to increase sales to the foreign market, with this representing 45% of total company's business in 2018 increasing of the number of markets through new partners to enable the positioning of Tubofuro® among the main players in each market, particularly in South American markets, North African and European. To achieve the above objectives presented a case study was applied, centred on Tubofuro® company, target of the internationalization strategy. The search carried out for the formulation of the strategy has been supported on a thorough analysis of the external environment and internal characteristics of the company, for which were crossed different types of data, quantitative, qualitative, secondary data and primary data. From this work resulted the development of internationalization and international marketing plan for the next three years, whose objectives are based on entrance and consequent growth in new markets, including the market Chilean, Peruvian, Mexican, Argentine, Algerian and German, as well growth in the presence and turnover in the markets for which Tubofuro® already exports regularly, for example Spain, France, Tunisia and Morocco. Based on the production capacity of Tubofuro® company, which will not suffer any kind of investment for incrementing but only to update, it is expected that the appropriate response capacity for the company is 8 regular markets, and could eventually arise sporadic exports to other markets not interfering with the normal production capacity of the company. The suggestion of the presented markets resulted from the study of the final price based on the one that local customers purchase a product equal or similar to Tubofuro® and the number of potential existing customers in each market. The internationalization model known as Uppsala Model corresponds to the strategy adopted by the company to its internationalization process, taking into account the philosophy of senior management and the risk aversion of them. The sales team Tubofuro® demand for each market, export a full container registering customer feedback, including quality and flow capacity in the market in order to seek a partnership agreement with a local distributor, which allows the Tubofuro® go to step two above mentioned model. The partnership agreement is based on mutual commitment to technical cooperation and trade between the Tubofuro® and partner, in order to increase the performance capacity among local customers. Only if the market presents a greater demand to our supply capacity and be justified by cost / benefit ratio, the entry into this market through a joint venture or subsidiary is that the decision will be taken. Although this is a case study, which means that is adjusted to the concrete case Tubofuro® preventing generalization of findings, we believe that this work can be a useful example for other companies in the internationalization process or the methodology adopted in formulating strategy or the outputs and conclusions drawn.

Estudio del tratado de libre comercio Colombia – Estados Unidos: Iowa, Kansas, Kentucky, Luisiana y Maine

Con el proceso de globalización que se evidencia actualmente, el comercio entre países ha sido uno de los factores más relevantes a través del tiempo y Colombia no ha sido excluyente a esta situación. Es por la importancia del asunto, que la Escuela de Administración dentro de sus múltiples proyectos de investigación busca la identificación de oportunidades para PYMES colombianas en mercados extranjeros, específicamente en Estados Unidos, asumiendo los retos que trae consigo un Tratado de Libre Comercio, las implicaciones en cuanto a los procesos de intercambio (importaciones y exportaciones) en sus diversos ámbitos y el impacto que genera dicho proceso en la balanza comercial colombiana. Debido a esto, se ha propuesto el desarrollo de un trabajo de grado que analice el Tratado de Libre Comercio (TLC) entre Colombia y Estados Unidos, enfocándose en los perfiles de cada mercado y las necesidades de los mismos, con el fin de identificar oportunidades generadas desde su puesta en marcha. En busca de un análisis detallado, el trabajo en mención hace énfasis en cinco estados de Estados Unidos (Iowa, Kansas, Kentucky, Luisiana y Maine) y los 32 departamentos de Colombia. Con el objetivo de realizar un análisis más efectivo se tomaron en cuenta las características de cada mercado y su relación comercial. A partir del previo proceso de investigación, se pretende identificar y definir oportunidades comerciales que evidencian una evolución comercial (mayor número de importaciones y exportaciones). Dichas oportunidades identificadas son el resultado de un análisis cualitativo tras desarrollar matrices de los principales diez productos más demandados por los Estados mencionados y los principales productos ofertados por los departamentos colombianos. Gracias a lo que enmarca un TLC dentro de un proceso de negociación, se proyecta identificar según las necesidades de las partes, es decir, oferta y demanda de bienes y/o 9 servicios, cada una de las oportunidades claves para los comerciantes nacionales que se involucran dentro del acuerdo aprobado.

Modelling trade offs between public and private conservation policies

To reduce global biodiversity loss, there is an urgent need to determine the most efficient allocation of conservation resources. Recently, there has been a growing trend for many governments to supplement public ownership and management of reserves with incentive programs for conservation on private land. This raises important questions, such as the extent to which private land conservation can improve conservation outcomes, and how it should be mixed with more traditional public land conservation. We address these questions, using a general framework for modelling environmental policies and a case study examining the conservation of endangered native grasslands to the west of Melbourne, Australia. Specifically, we examine three policies that involve i) spending all resources on creating public conservation areas; ii) spending all resources on an ongoing incentive program where private landholders are paid to manage vegetation on their property with 5-year contracts; and iii) splitting resources between these two approaches. The performance of each strategy is quantified with a vegetation condition change model that predicts future changes in grassland quality. Of the policies tested, no one policy was always best and policy performance depended on the objectives of those enacting the policy. Although policies to promote conservation on private land are proposed and implemented in many areas, they are rarely evaluated in terms of their ecological consequences. This work demonstrates a general method for evaluating environmental policies and highlights the utility of a model which combines ecological and socioeconomic processes.

The relationship between BCOM1 gene variants and macular pigment optical density in persons with and without age-related macular degeneration

Background: Recent evidence indicates that gene variants related to carotenoid metabolism play a role in the uptake of macular pigments lutein (L) and zeaxanthine (Z). Moreover, these pigments are proposed to reduce the risk for advanced age-related macular degeneration (AMD). This study provides the initial examination of the relationship between the gene variants related to carotenoid metabolism, macular pigment optical density (MPOD) and their combined expression in healthy humans and patients with AMD. Participants and Methods: Forty-four participants were enrolled from a general population and a private practice including 20 healthy participants and 24 patients with advanced (neovascular) AMD. Participants were genotyped for the three single nucleotide polymorphisms (SNPs) upstream from BCMO1, rs11645428, rs6420424 and rs6564851 that have been shown to either up or down regulate beta-carotene conversion efficiency in the plasma. MPOD was determined by heterochromatic flicker photometry. Results: Healthy participants with the rs11645428 GG genotype, rs6420424 AA genotype and rs6564851 GG genotype all had on average significantly lower MPOD compared to those with the other genotypes (p < 0.01 for all three comparisons). When combining BCMO1 genotypes reported to have “high” (rs11645428 AA/rs6420424 GG/rs6564851 TT) and “low” (rs11645428 GG/rs6420424 AA/rs6564851 GG) beta-carotene conversion efficiency, we demonstrate clear differences in MPOD values (p<0.01). In patients with AMD there were no significant differences in MPOD for any of the three BCMO1 gene variants. Conclusion: In healthy participants MPOD levels can be related to high and low beta-carotene conversion BCMO1 genotypes. Such relationships were not found in patients with advanced neovascular AMD, indicative of additional processes influencing carotenoid uptake, possibly related to other AMD susceptibility genes. Our findings indicate that specific BCMO1 SNPs should be determined when assessing the effects of carotenoid supplementation on macular pigment and that their expression may be influenced by retinal disease.

The trade-off between incentives and endogenous risk

Standard models of moral hazard predict a negative relationship between risk and incentives, but the empirical work has not confirmed this prediction. In this paper, we propose a model with adverse selection followed by moral hazard, where effort and the degree of risk aversion are private information of an agent who can control the mean and the variance of profits. For a given contract, more risk-averse agents suppIy more effort in risk reduction. If the marginal utility of incentives decreases with risk aversion, more risk-averse agents prefer lower-incentive contractsj thus, in the optimal contract, incentives are positively correlated with endogenous risk. In contrast, if risk aversion is high enough, the possibility of reduction in risk makes the marginal utility of incentives increasing in risk aversion and, in this case, risk and incentives are negatively related.

Trade-offs between timber production and biodiversity in rainforest plantations: Emerging issues and an ecological perspective

During the past two centuries there have been three major paradigm shifts in the management of Australian rainforests and the use of their timbers: from felling native forests towards growing plantations; from viewing forests and plantations as mainly providers of timber to viewing them as sources of multiple benefits (e.g. timber, biodiversity, carbon sequestration, catchment protection, recreation, regional economic development); and from timber plantations being developed mainly by government on public land towards those established by private citizens, companies, or joint venture arrangements, on previously-cleared freehold land. Rainforest timber plantations are increasingly established for varied reasons, and with multiple objectives. Landholders are increasingly interested in the biodiversity values of their plantations. However, there are few guidelines on the changes to plantation design and management that would augment biodiversity outcomes, or on the extent to which this might require a sacrifice of production.
