Ion heating in transitions to CERC in the stellarator TJ-II

In TJ-II stellarator plasmas, in the electron cyclotron heating regime, an increase in the ion temperature is observed, synchronized with that of the electron temperature, during the transition to the core electron-root confinement (CERC) regime. This rise in ion temperature should be attributed to the joint action of the electron–ion energy transfer (which changes slightly during the CERC formation) and an enhancement of the ion confinement. This improvement must be related to the increase in the positive electric field in the core region. In this paper, we confirm this hypothesis by estimating the ion collisional transport in TJ-II under the physical conditions established before and after the transition to CERC. We calculate a large number of ion orbits in the guiding-centre approximation considering the collisions with a background plasma composed of electrons and ions. The ion temperature profile and the thermal flux are calculated in a self-consistent way, so that the change in the ion heat transport can be assessed.

Towards the Consideration of the U.S. Community College Model to Address the Need for Higher Education Reforms in Ghana

ABSTRACT The higher education systems throughout the continent of Africa are undergoing unprecedented challenges and are considered in crisis. African countries, including Ghana, all have in common ties to their colonial legacy whereby they are confronted with weak policies put in place by their colonizers. Having gained their independence, Africans should now take responsibility for the task of reforming their higher education system. To date, nothing substantial has been accomplished, with serious implications for weakening and damaging the structures of the foundation of their educational systems. This qualitative, single case study utilized a postcolonial theory-critical pedagogy framework, providing guidance for coming to grips with the mindset posed by Ghana's colonial heritage in the postcolonial era, especially in terms of its damaging effects on Ghana's higher education system. The study explores alternative pathways for secondary school students to transition to tertiary education--a problematic transition that currently hinders open access to all and equality in educational opportunity, resulting in a tremendous pool of discontinued students. This transitional problem is directly related to Ghana's crisis in higher education with far reaching consequences. The alternative pathway considered in this study is an adaptation of the U.S. community college model or an integration of its applicable aspects into the current structures of the higher education system already in place. In-depth interviews were conducted with 5 Ghanaian professors teaching at community colleges in the United States, 5 Ghanaian professors teaching at universities in Ghana, and 2 educational consultants from the Ghanaian Ministry of Education. Based on their perspectives of the current state of Ghanaian higher education, analyzed in terms of pedagogy, structure/infrastructure, and curriculum, the participants provided their perceptions of salient aspects of the U.S. community college model that would be applicable to Ghana's situation, along with other recommendations. Access to all, including equality of educational opportunity, was considered essential, followed by adaptability, affordability, practicality, and quality of curriculum content and delivery. Canada's successful adaptation of the U.S. model was also discussed. Findings can help guide consideration of alternative pathways to higher education in Ghana and Africa as a whole.

Parti communiste et féminisme. De l’antifascisme à la transition démocratique en Espagne

Dans les années 1930, les femmes membres du Parti communiste espagnol (PCE) collaborent avec des représentantes du féminisme et réclament une égalité pour les femmes sans pour autant se déclarer féministes. Pendant la guerre civile, elles ne remettent pas en question l’attribution de tâches maternelles aux femmes, mais elles revendiquent une participation politique dans les mêmes conditions que les hommes. Au cours des années 1970 cependant, la culture politique communiste traditionnelle, qui repose sur une relation de genre inégale, est remplacée par une nouvelle culture, dans laquelle socialisme et égalité vont de pair. Pendant la transition démocratique, les militantes se considèrent comme féministes et demandent que les fondements théoriques du féminisme soient assumés par le Parti.

Bringing the Past Back in: How Attitudes towards the Democratic Transition Influence the Portuguese Voter

This article analyses the way in which attitudes towards the transition to democracy explain party identification and ideology in Portugal. This question is important because the transition to democracy in Portugal was a turbulent process marked by a rupture with the past and institutional fluidity. It has also conditioned the main political parties’ relationships with the electorate and each other since 1974. I compare the same explanatory model results from two surveys, conducted in 2004 and 2014, respectively, to understand the extent to which perceptions about the transition help characterise the Portuguese voter over the last decade.

Opportunities and challenges in the area of employment, social affairs, skills and labour mobility. EPC Commentary, 30 September 2014

On 1 October 2014, Marianne Thyssen, Commissioner-designate for Employment, Social Affairs, Skills and Labour Mobility, will face a European Parliament (EP) hearing. On this occasion, Thyssen will have to perform a delicate balancing act consisting of on the one hand, taking into consideration the significant budget constraints that a number of Member States are still facing and following the still prevailing political line of fiscal consolidation and sound public finances, and on the other hand, of demonstrating her strong commitment for Social Europe. In the context of the upcoming hearing, this commentary aims to outline the features, opportunities and challenges of the new portfolio related to employment and social affairs in view to providing an input into the political debate.

Analysing the Contribution of Business Services to European Economic Growth. Bruges European Economic Research (BEER) Papers 9/February 2007

The sector business services contributes directly and indirectly to aggregate economic growth in Europe. The direct contribution comes from the sector’s own dynamism. Though the business-services industry appears to be characterised by strong cyclical volatility, there was also a strong structural growth. Business services actually generated more than half of total net employment growth in the European Union since the second half of the 1990s. Apart from this direct growth contribution, the sector also contributed in an indirect way to economic growth by generating knowledge and productivity spill-overs for other industries. The knowledge role of business services is reflected in its employment characteristics. The business-services industry created spill-overs in three ways: original innovations, knowledge diffusion, and the reduction of human capital indivisibilities at firm level. The share of knowledge-intensive business services in the intermediate inputs of the total economy has risen sharply in the last decade. Firm-level scale diseconomies with regard to knowledge and skill inputs are reduced by external deliveries of such inputs, thereby exploiting positive external scale economies. The process goes along with an increasingly complex social division of labour between economic sectors. The European business-services industry itself is characterised by a relatively weak productivity growth. Does this contribute to growth stagnation tendencies à la the socalled “Baumol disease”? The paper argues that there is no reason to expect this as long as the productivity and growth spill-overs from business services to other sectors are large enough. Finally, the paper concludes by suggesting several policy elements that could boost the role of business services in European economic growth. This might to achieve some of the ambitious Lisbon goals with respect to employment, productivity and innovation.

The Tunisian Revolution: An Opportunity for Democratic Transition. MEDPRO Commentary, 24 January 2011

To help promote a peaceful transition to democracy in Tunisia, a new MEDPRO Commentary by Rym Ayadi, Silvia Colombo, Maria Cristina Paciello and Nathalie Tocci calls upon the EU to act quickly on its declaration of support for “a genuine democratic transition” and to consult with political parties both from the transition government and beyond to prepare for the running of the next elections. A positive resolution of this crisis will only be achieved if the internal and external players follow the lessons of successful democratic transitions elsewhere.
