Some mathematical properties of a DEA model for the joint determination of efficiencies
No full textThis paper explores the Kuhn-Tucker conditions and convexity in a non-linear DEA model for the joint determination of efficiencies developed by Mar Molinero (1994). It is shown that the usual convexity conditions that apply to Linear Programming problems are satisfied in this case. First order Kuhn-Tucker conditions are derived and interpreted. Estimation strategies are suggested. Some empirical work is reporte
The politics of language in the Spanish-speaking world: from colonisation to globalisation
No full textSpanish is now the third most widely spoken language in the world after English and Chinese. This book traces how and why Spanish has arrived at this position, examining its role in the diverse societies where it is spoken from Europe to the Americas. Providing a comprehensive survey of language issues in the Spanish-speaking world, the book outlines the historical roots of the emergence of Spanish or Castilian as the dominant language, analyzes the situation of minority language groups, and traces the role of Spanish and its colonial heritage in Latin America. The book is structured in four sections: Spanish as a national language: conflict and hegemony Legislation and the realities of linguistic diversity Language and education The future of Spanish. Throughout the book Clare Mar-Molinero asks probing questions such as: How does language relate to power? What is its link with identity? What is the role of language in nation-building? Who decides how language is taught

No full textAnita Molinero © Johann Bouché Pillon At the end of the 1970s, at a time when minimalism and Supports/Surfaces dominated contemporary art, Anita Molinero discovered Arte povera and Art informel in a class taught by sculptor Toni Grand at the école des Beaux-Arts in Marseille, opening an avenue of research into “miserable” and “semi-permanent” forms. Anita Molinero started to explore the waste our industrial society constantly overproduces. She shares with Eva Hesse, David Hammons and Franz We..
Developing “SotonSmartSkills”: A reflection on scaffolded independent learning programmes
No full textBy focussing on the physical and virtual space of a Language Resources Centre and the development of a wide set of digital literacies skills, this article discusses the SotonSmartSkills (Mar-Molinero & Lewis, 2014) programme developed at the University of Southampton, UK. Through a wide range of scaffolded courses designed to support the transition to the learner autonomy required of students in Higher Education, the programme equips students with skills, strategies, techniques and tools vital for success in their language learning (for international students) and more generally, in their academic achievement and professional life. In this paper we illustrate this initiative with the specific example of an integrated SotonSmartSkills module on our Pre-Sessional English programme

Anita Molinero commence donc à s’intéresser aux rebuts d’une société industrielle en constante surproduction. Elle partage avec Eva ..
Deconstruyendo la paz liberal en África Subsahariana
No full textEl número incluye a su vez, un review-essay realizado por Yoan Molinero sobre las
obras El sueño liberal en África Subsahariana. Debates y controversias sobre la construcción
de la paz, editado por Itziar Ruiz-Giménez, y State and Societal Challenges in the Horn of
Africa. Conflict and processes of state formation, reconfiguration and disintegration, editado
por Alexandra Magnolia, ambos publicados en 2013. En este review, titulado “Deconstruyendo
la paz liberal en África Subsahariana”, el autor analiza el despliegue del proyecto liberal en
África, centrado en la construcción del estado liberal y las contradicciones que éste plantea.
Por medio del análisis de un libro que trata de la construcción de la paz en el continente
y otro centrado en un caso paradigmático como es el Cuerno de África, Yoan Molinero
muestra cómo gran parte de los problemas que el proyecto liberal suscita en África, incluidos
conflictos como los que asolan gran parte del Cuerno de África, provienen de los errores
y contradicciones propios de este proyecto, tales como diagnósticos equivocados sobre el
origen de la conflictividad, el carácter exógeno y la “iliberalidad” del proyecto de la paz liberal,
la implementación de un determinado modelo de estado, etcPeer reviewe
Selecting DEA specifications and ranking units via PCA
No full textDEA model selection is problematic. The estimated efficiency for any DMU depends on the inputs and outputs included in the model. It also depends on the number of outputs plus inputs. It is clearly important to select parsimonious specifications and to avoid as far as possible models that assign full high efficiency ratings to DMUs that operate in unusual ways (mavericks). A new method for model selection is proposed in this paper. Efficiencies are calculated for all possible DEA model specifications. The results are analysed using Principal Components Analysis. It is shown that model equivalence or dissimilarity can be easily assessed using this approach. The reasons why particular DMUs achieve a certain level of efficiency with a given model specification become clear. The methodology has the additional advantage of producing DMU rankings
Profiling, developing, and assessing effective strategies for managing learning and behaviour
No full textA structured observational protocol aimed at recording and profiling interaction strategies between teachers and pupils is developed in this paper. The principles on which the protocol is based are described. It was piloted at a junior school following an OFSTED inspection with the aim of collecting systematic data on teacher-pupil interaction. This was needed in order to assess the effectiveness of behaviour management strategies. The success of the project lead to the protocol being used by educational psychologists at other schools. Out-reach teachers at a special school for pupils with emotional and behavioural difficulties were trained in the use the protocol to support teachers managing pupils in mainstream schools. The assessment of the approach was made with the help of multidimensional scaling and associated multivariate statistical techniques
An approach to the measurement of intangible assets in dot com based on web metrics and financial information
No full textA sample of 76 firms that operate in the Internet is studied in order to explore forms of identifying and measuring intangible assets in this area of business. The firms meet three conditions: operate in the Internet, have available accounting information, and be quoted in the stock exchange. Data was obtained on two successive years for four web metrics indicators, 30 ratios that combine accounting and web traffic information, 31 accounting ratios, a measure of stock exchange performance, and a measure of efficiency based on Data Envelopment Analysis. Modelling relied on multivariate statistical approaches: Factor Analysis, Scaling techniques, multivariate regression, and hierarchical cluster analysis. Two intangible assets were identified: one was related to internal structure and was associated with managerial efficiency; and another one was associated with external image and customer loyalty. Comparison between the two years found many changes, confirming the view that this is a very dynamic sector, although the main conclusions remained unchanged
An approach to the measurement of intangible assets in public sector using scaling techniques
No full textThis paper discusses the identification and measurement of intangible assets in the public sector. A discussion of Intellectual Capital theory identifies and classifies a number of intangible assets of relevance to the Public Sector. Multidimensional Scaling and related multivariate techniques are proposed for their detection and quantification. The methodology is illustrated with a case study: the provision of council services through the Internet by Spanish municipalities. The technique identifies three intangible assets related to external structural capital: service, image and transparency. Five strategic groups reveal the different objectives, strategic use of Internet, and actions taken by the various Spanish councils
