The context of oil platform design is changing in order to increase competitiveness and be prepared for difficult operations, mainly in fields more distant from the coast, like pre-salt. The currently preceding context is marked by projects guidelines designed to reduce projects and operation costs, including an important reducing in the number of people on board. The main objective of this research is to verify and discuss if the experience of use in platforms designed in a previous context, in which the people on board is practically twice, can contribute and/or can be transferred to new projects. From the ergonomic intervention in the design of two oil platform, with the work of team on board investigated on previous projects as reference, it was possible analyze if the previous use is still applicable to new projects. As a result, about 90% of the recommendations based on use are applicable to the current context. The restrictions on the transfer or operational experience are mainly related to the time of entry of ergonomics in the design process, the subsequent transformations costs and the advance of the execution phase started with the detailed design. 相似文献

In sum, this paper examines the core determinants of lottery sales in Portugal. With panel data analysis covering 18 Portuguese districts and 5 years, this study explains the variations in a district’s per-capita lottery sales in terms of key theoretical hypotheses such as per capita district income, age, education index, gender and religion. This paper concludes that the richer Portuguese districts spend more than the poorer districts and there is an inverted-U relationship between lottery sales and per capita income. The paper also concludes that married Catholic citizens spend more on lottery products than others and that the level of education returns a negative effect on lottery spending. 相似文献

The Mexican legend of ‘La Llorona’ (‘The Weeping Woman’), who drowned her children out of revenge for being abandoned by her lover, and the Aztec creation myth of ‘The Hungry Woman’ — crying constantly for food, with mouths all around her body — have inspired Chicana writers in the symbolic representation of their own yearning, be it sexual, identity-building, or anti-patriarchal. This essay seeks to lay the mythical groundwork within this topic, as well as to illustrate with some particular examples the different reappropriations of these myths in Cherríe L. Moraga, mainly in her play The Hungry Woman: A Mexican Medea (2001). With a view to opening up a past ‘that can provide a kind of road map to our future’ (: ix), these examples of transgressive women will be deprived of the feminine colonial passivity imbued by the dominant male discourse, and analysed as a complex, active, polyvalent mythological female corpus that integrates both life and death, womb and grave. This hybrid approach is inherent to the Aztec mythology on which Moraga relies in order to transcend Manichaeistic resolutions and probe the social, political, and gender reasons leading a hungry mother to commit infanticide. 相似文献

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision. 相似文献

In the early seventeenth century, important socioeconomic changes in the Spanish colony of Hispaniola brought about substantial shifts in race relations between white residents and peoples of African descent, who were enslaved and free. As the plantation system declined precipitously, white members of the Spanish elite started envisioning new roles for enslaved laborers, which included enrolling these enslaved peoples in their own intrigues against other elites. This cooperation led people in bondage to carry out violent attacks and assassination plots against other members of the white colonial society. People of African descent took advantage of these collaborations as an opportunity to advance their own interests within the community. Nevertheless, people of African descent faced fierce and often violent backlash if they acted of their own accord. 相似文献

In therapeutic conversations, questions can be considered as interventions in their own right. This study is a cross‐cultural replication of Grant (Journal of Systemic Therapies, 2012, 31, 2, 21) study on the effects of different types of questions on various clinically relevant variables. A total of 204 students of a Spanish university described a real‐life problem that they wanted to solve and were then randomly assigned to either a solution‐focused or a problem‐focused questions condition. Before and after answering the questions, they completed a set of measures that assessed positive and negative affect, self‐efficacy, and goal attainment. Solution‐focused questions produced a significantly greater increase in self‐efficacy, goal approach, and action steps than problem‐focused questions, and a significantly greater decrease in negative affect, providing further empirical support to solution‐focused practices. 相似文献

In 2015, Lusophone Africa celebrated 40 years since independence. Portuguese colonies in Africa became independent in the aftermath of two orders of interlinked events. The first was the fierce-armed opposition to the colonial order – through the action of nationalist movements and nationalist thinkers such as Amílcar Cabral – which escalated after 1960 when French and English colonies in Africa were achieving independence. The second was the Carnation Revolution, in 1974, which, despite having taken place in Lisbon, had powerful reverberations across Portuguese Africa. Here, I argue that the Carnation Revolution was a by-product of the emergence of nationalist movements in Africa, when it became apparent that popular uprisings there could not be won by conventional armed struggle. Or, to put it slightly different, anticolonial struggle in Africa opened the way not only for the end of Portuguese rule on the continent, but also for the demise of dictatorship in Portugal itself. 相似文献

Throughout Latin America, the relationship between government and civil society organizations (CSOs) has been characterized by opposition, substitution, and submission; and, the incipient path to cooperation is barely noticeable. For their part, participatory public policies make sense within a theory of democratic governance. Democratic governance seeks two propositions: (a) participation from other social actors will give rise to more efficient government action; and (b) citizen support will emerge from the said government action. This paper criticizes the current relationships between the governments and CSOs in this region. In addition, it explores the potential strategies that could be adopted were there a cooperation between these two entities. The paper is supported by theoretical literature as well as by a revision of some cases of participatory public policies that are currently active in the region. The paper proposes that the strategies of opposition to government and government substitution have to be abandoned in this region. The paper focuses on civil organizations (CSOs). It is true that they do not constitute the entirety of civil society; however, they are frequently the most organized compared with other civic actors, such as social movements, families, and individual initiatives. CSOs form only a part of the diversity known as civil society; however, they significantly contribute to the discussion about the public good, and very often they participate in providing such goods. The future of participatory democracy in Latin America is related to our ability to achieve a more complete participation of CSOs in the entire process of participatory public policies—from the formation of public agendas to their design, implementation, and evaluation. 相似文献

In today’s Latin America, governments implementing public policies for development and against poverty and inequality meet with social movements that engage in practices for social change, poverty reduction, and empowering. In this context, we analyze the interplay between both processes, describing its conflicts in three specific dimensions: the material, the democratic, and the environmental. Social movements are permanently contesting and challenging public policy when they autonomously appropriate public policy resources; yet, governments respond with criminalization and cooptation strategies. In a setting where social conflict takes place in response to existing poverty and inequality levels, movements challenge development and poverty reduction projects of an ‘assistentialist’ and extractivist nature, and propose an integral understanding of development and the emergence of new relationships among individuals, society, and the environment. 相似文献

It is usually considered that the proportion of handicapped people grows with age. Namely, the older the man/woman, the more the level of disability he/she suffers. However, empirical evidence shows that this assessment is not always true, or at least, it is not true in the Spanish population. The study tries to assess the impact of age on disability in Spain. Each gender has been treated separately because it can be shown that men and women have their own pattern of behaviour. Three different methods of estimation have been used to check the link between those variables. The results seem to support the idea that the relationship among age and the intensity of disability is not always direct. One of the concluding remarks in this analysis is that the method of estimation has a great incidence in the final results, especially in central ages between 20 and 80 years old. 相似文献
