Factorial Validation of Warr’s (1990) Well-Being Measure: A Sample Study on Police Officers  [PDF]
Sónia P. Gon?alves, José Neves
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.27108
Abstract: The purpose of this study was to test the factorial validity of the job-related affective well-being scale—the IWP Multi-Affect Indicator. The sample was composed of 1466 police officers and collected through self-report questionnaires. With the objective of validating the factorial structure of the IWP Multi-Affect Indicator, several models were tested using confirmatory factor analysis. The results supported a four-factor structure: anxiety, comfort, depression and enthusiasm, as well as a five-factor structure including the same four factors plus a second-order factor called global affective well-being.
A Uni?o Europeia entre o alargamento e a vizinhan?a: os casos dos Balc?s ocidentais e do Cáucaso do sul
Sim?o, Licínia;Rodrigues, Sónia;
Revista Brasileira de Política Internacional , 2012, DOI: 10.1590/S0034-73292012000100004
Abstract: the paper deals with eu policies towards its eastern periphery, focusing on the western balkans and south caucasus. departing from a comparative approach, the paper argues that the establishment of a regional normative order, with clear goals of stabilization through variable geometry integration, has found clear limits. the paper flashes out these dynamics and establishes important lessons to be learned from the european approach to the balkans and the caucasus.
Producing a “Successful City”: Neoliberal Urbanism and Gentrification in the Tourist City—The Case of Palma (Majorca)
Sònia Vives Miró
Urban Studies Research , 2011, DOI: 10.1155/2011/989676
Abstract: Since the 1990s, the intensification of capital accumulation, especially in its financial dimension, has been one of the keystones for the triumph of neoliberalism. Spanish neoliberal policies have focused on the flexibilization of the real estate sector, leading to the specialization in the secondary circuit of accumulation. This has generated a third real estate boom which has been accompanied with an outstanding housing bubble. The Balearic Islands are a paradigmatic case within these logics, tourist specialization being the main trigger of the process. In Palma, the region's capital, neoliberal urban planning policies have been implemented in order to convert it into a “successful city” within the global urban network competition. These policies have led to Palma's uneven geographical development through processes like gentrification, as is the case of the Gerreria, a neighborhood of Palma's city center. 1. Introduction Fernádez Durán [1] has defined the Spanish physical and social landscape transformation as an urban-development tsunami. The specialization of the Spanish capitalism in the secondary circuit of accumulation has been understood as the spatiotemporal solution to the crisis of the nineties [2]. (Harvey [3] introduced Marxist analysis in order to explain the capitalist urban process. According to Harvey [3], the secondary circuit of accumulation is based on two parts: the formation of fixed capital and the consumption fund. On the one hand, fixed capital consists in the physical framework which aids the production process, used over a long-time period. It is the machines and the factories, but also public works. On the second hand, the consumption fund comprises commodities that aid the production process, items enclosed within the consumption process, and others acting as physical framework for consumption. It is consumer durables and the built environment for consumption such as housing). The production of new space is subordinated to the logics of the regime of flexible accumulation through financialization, flexibility, and privatization. Since the nineties, the expansion of neoliberalism has involved the entrepreneurial turn of local governments, by playing a new role in the urban governance. Local governments, in conjunction with private agents and urban elites, have turned into promoters developers, producing the city based on competitive logics, in order to scale positions in the global urban hierarchy. In this sense, gentrification policies have been one of the main urban strategies that have driven cities towards success in the
Aluminium Toxicity Targets in Plants
Sónia Silva
Journal of Botany , 2012, DOI: 10.1155/2012/219462
Abstract: Aluminium (Al) is the third most abundant metallic element in soil but becomes available to plants only when the soil pH drops below 5.5. At those conditions, plants present several signals of Al toxicity. As reported by literature, major consequences of Al exposure are the decrease of plant production and the inhibition of root growth. The root growth inhibition may be directly/indirectly responsible for the loss of plant production. In this paper the most remarkable symptoms of Al toxicity in plants and the latest findings in this area are addressed. Root growth inhibition, ROS production, alterations on root cell wall and plasma membrane, nutrient unbalances, callose accumulation, and disturbance of cytoplasmic Ca2+ homeostasis, among other signals of Al toxicity are discussed, and, when possible, the behavior of Al-tolerant versus Al-sensitive genotypes under Al is compared. 1. Introduction Aluminium (Al) ranks third in abundance among the Earth’s crust elements, after oxygen and silicon, and is the most abundant metallic element. A large amount of Al is incorporated into aluminosilicate soil minerals, and very small quantities appear in the soluble form, capable of influencing biological systems [1]. Al bioavailability, and in consequence, toxicity, is mainly restricted to acid environments. Acid soils (with a pH of 5.5 or lower) are among the most important limitations to agricultural production. The production of staple food crops, in particular grain crops, is negatively influenced by acid soils [2]. Some agricultural practices, as removal of products from the farm, leaching of nitrogen below the plant root zone, inappropriate use of nitrogenous fertilizers, and build-up in organic matter, are causing further acidification of agricultural soils. When pH drops below 5.5, aluminosilicate clays and aluminium hydroxide minerals begin to dissolve, releasing aluminium-hydroxy cations and A l ( H 2 O ) 6 3 + ( A l 3 + ), that then exchange with other cations. On that conditions, A l 3 + also forms the mononuclear species A l O H 2 + , A l ( O H ) 2 + , Al(OH)3, and Al(OH)4 [3]. The mononuclear A l 3 + species and Al13 are considered as the most toxic forms [4, 5]. Although some crops (e.g., pineapple, tea) are considered tolerant to high levels of exchangeable Al, for most crops it is a serious constraint. Species and genotypes within species greatly differ in their tolerance to Al. For most crops, fertilization and attempts of soil correction (e.g., liming) may not be enough per se to reduce Al toxicity (e.g., as the soil reaction remains strongly

Cultura pop: astúcia e inocência
Salzstein, Snia;
Novos Estudos - CEBRAP , 2006, DOI: 10.1590/S0101-33002006000300014
Abstract: this essay focuses the intensive ideological reconfigurations to which the term "pop" fell prey in the artistic and cultural debate of the last quarter of the twentieth century. during these years, pop was claimed or as a wedge in a new and wholesome cultural era or as the grandiose accomplishment of the "historical art", from which finally would rise "art" as a pure concept. it also discusses the contemporary remains of this debate - a "pop issue" follows being its kernel - and analyses specially the role that multiculturalist currents have had in this context.
