Teacher training in "multicultural" Sweden

This paper builds on the experience of the on-going, mainly ethnographic, research project called Teacher training in’ multicultural’ Sweden. Class, gender and ethnicity. In this multi-disciplinary project a number of scholars conduct research through participant observation in, and through the study and analysis of documents from, a number of teacher training colleges in Sweden. In this paper I will use empirical material gathered from two teacher training colleges to discuss this basic issue. One college is situated in a suburb outside Stockholm and it consciously portrays itself as a college for ‘multicultural’ students who will later teach in ‘multicultural’ suburbs. The other college is situated in a small town and although ‘multiculturalism’ is seen as important in the educational system students with mainly ‘Swedish’ background are recruited. In the first college ‘differences’ are lauded and students are encouraged to ponder upon and develop their ethnic profile. In the second ‘similarities’ are more taken for granted. I will argue, however, that within these colleges ‘differences’ and ’similarities’ are not only discussed but actually created against a backdrop of macro-constraints which are not much scrutinized within these colleges.

International accounting harmonisation - A comparison of Spain, Sweden and Austria

Despite attempts to secure harmonisation of accounting practice,significant variations in accounting rules and practice continueto arise in European countries, variations which give rise tocompliance costs for multinational companies.Firstly, this paper considers the relevance of internationalaccounting harmonisation for European business. It then proceedsto examine accounting regulation in three countries: Spain, Swedenand Austria, highlighting the key regulatory issues of the 'trueand fair' view requirement and the link between taxation andaccounting. The three countries are selected because of theinteresting contrasts which they provide; these contrasts areexamined in detail in the paper.The work is based upon a series of interviews carried out withleading accounting practitioners in the three countries during1996-97.The paper concludes that there are significant obstacles toaccounting harmonisation in Europe and that there is potentialfor continuing diversity of national accounting practice.

Simulación Monte Carlo de las dosis en tumores de pulmón en tratamientos de radioterapia estereotáxica extracraneal

Estudio elaborado a partir de una estancia en el Karolinska University Hospital, Suecia, entre marzo y junio del 2006. En la radioterapia estereotáxica extracraneal (SBRT) de tumores de pulmón existen principalmente dos problemas en el cálculo de la dosis con los sistemas de planificación disponibles: la precisión limitada de los algoritmos de cálculo en presencia de tejidos con densidades muy diferentes y los movimientos debidos a la respiración del paciente durante el tratamiento. El objetivo de este trabajo ha sido llevar a cabo la simulación con el código Monte Carlo PENELOPE de la distribución de dosis en tumores de pulmón en casos representativos de tratamientos con SBRT teniendo en cuenta los movimientos respiratorios y su comparación con los resultados de varios planificadores. Se han estudiado casos representativos de tratamientos de SBRT en el Karolinska University Hospital. Los haces de radiación se han simulado mediante el código PENELOPE y se han usado para la obtención de los resultados MC de perfiles de dosis. Los resultados obtenidos para el caso estático (sin movimiento respiratorio ) ponen de manifiesto que, en comparación con la MC, la dosis (Gy/MU) calculada por los planificadores en el tumor tiene una precisión del 2-3%. En la zona de interfase entre tumor y tejido pulmonar los planificadores basados en el algoritmo PB sobrestiman la dosis en un 10%, mientras que el algoritmo CC la subestima en un 3-4%. Los resultados de la simulación mediante MC de los movimientos respiratorios indican que los resultados de los planificadores son suficientemente precisos en el tumor, aunque en la interfase hay una mayor subestimación de la dosis en comparación con el caso estático. Estos resultados son compatibles con la experiencia clínica adquirida durante 15 años en el Karolinska University Hospital. Los resultados se han publicado en la revista Acta Oncologica.

Landscape context on generalist and specialist aphid natural enemies

Report for the scientific sojourn at the University of Lund, Sweden, between May and September 2007. A landscape-scale research approach has been highlighted by a growing body of literature as essential for understanding important ecosystem services as biological control. Aphids are victims of a diversity of enemies making the aphid-enemy interaction a nice example for the role of enemy diversity for the functioning of biological control. Here it is examined the effects of landscape complexity on cereal aphids and associated natural enemies that varied in the degree of specialization. Parasitoids wasps abundance did not differ between landscape types but was strongly negatively related to the percentage of arable land. In contrast, abundances of generalist predators like Coccinellidae were significantly higher in simple landscapes since can benefit from the high availability of a variety of alternative resources within cropping systems. Consequently coccinellidae-to-aphid ratio was significantly higher in fields in homogenous landscapes as compared to fields included in an heterogeneous landscape, suggesting that enemy pressure on cereal aphids increases with landscape simplification. The landscape effect will depend mainly on the degree of specialization of functionally dominant natural enemies, so that the results imply that conservation actions aiming to optimise abundance for one taxonomic group in the agricultural landscape will not automatically increase abundance of other groups. Given that the strength of natural enemy impact on biocontrol depends on landscape features and the role of functionally dominant natural enemies. So, therefore it is essential to focus the future empirical work in examining the schedule of agricultural landscapes that maintain a diversity of generalist and specialist natural enemies.

Analog Modelling of N-S anticlines of the External Sierras (Jaca basin, Southern Pyrenees)

Report for the scientific sojourn carried out at the Uppsala Universitet, Sweden, from April to July the 2007. Two series of analogue models are used to explore ductile-frictional contrasts of the basal décollement in the development of oblique and transverse structures simultaneously to thin-skinned shortening. These models simulate the evolution of the Central External Sierras (Southern Pyrenees, Spain), which constitute the frontal emerging part of the southernmost Pyrenean thrust sheet. They are characterized by the presence of transverse N-S to NW-SE anticlines, which are perpendicular to the Pyrenean structural trend and developed in the hangingwall of the Santo Domingo thrust system, detaching on an unevenly distributed Triassic materials (evaporitic-dolomitic interfingerings). Model setup performs a décollement made by three patches of silicone neighbouring pure brittle sand. Model series A test the thickness ratio between overburden and décollement. Model series B test the width of frictional detachment areas. Model results show how deformation reaches further in areas detached on ductile layer whereas frictional décollement areas assimilate the strain by means of an additional uplift. This replicates the structural style of Central External Sierras: higher structural relief of N-S anticlines with regard to orogen-parallel structures, absence of a representative ductile décollement in the core, tilting towards the orogen and foreland-side closure not thrusted by the frontal emerging South-Pyrenean thrust.

Aproximació a la figura dels Business Angels

Els business angels són persones físiques que inverteixen una part dels seus diners en empreses joves, tot just acabades de crear, en alguns casos fins i tot ajuden a crear-les. El nom d’àngels té el seu origen en els rics filantrops de Nova York que finançaven les obres que s’estrenaven a Broadway. Aquests filantrops invertien els seus diners en una obra de teatre, pel plaer de contribuir a la cultura, molt sovint no arribaven a recuperar mai aquests diners. Els business angels, no són filantrops, inverteixen esperant guanyar diners, però al igual que els àngels de Broadway, els mou alguna cosa més que els diners, ja que està àmpliament documentat que darrera d’aquestes inversions hi ha també raons no financeres, com ara fomentar l’esperit emprenedor o fins i tot la cerca de diversió. Podríem dir que el terme “business angel” es va encunyar a principis dels 80 als EUA, per tant aviat farà 30 anys, no obstant, encara avui, la majoria de catalans no coneixen el significat d’aquest terme. A Catalunya i Espanya anem terriblement retardats en l’estudi i la promoció d’aquesta figura en relació a països com els EUA i el Regne Unit, però també massa enrera en relació a països com Finlàndia, Suècia, Noruega i Alemanya. L’objectiu d’aquest treball és doncs oferir una complerta aproximació a aquesta figura del business angel, una figura que entenem clau en el desenvolupament empresarial i per tant una figura que cal potenciar a tots els nivells. Per tal de contextualitzar aquesta important figura, el treball parteix de l’anàlisi de la relació existent entre emprenedoria i creixement econòmic, s’endinsa després en el capital risc, per presentar finalment qui és i que fa el business angel. El treball intenta també mostrar l’abús d’usos i la inconsistència de les definicions que es donen del terme “business angel” i per tant la gran confusió que tot això genera.

Trends in economic research: an international perspective

Given the recent efforts in several countries to reorganize the research institutional setting to improve research productivity, our analysis addresses the following questions: To which extent has the recent awareness over international quality standards in economics around the world been reflected in research performance? How have individual countries fared? Do research quantity and quality indicators tell us the same story? We concentrate on trends taking place since the beginning of the 1990s and rely on a very comprehensive database of scientific journals, to provide a cross-country comparison of the evolution of research in economics. Our findings indicate that Europe is catching-up with the US but, in terms of influential research, the US maintains a dominant position. The main continental European countries, Germany, France, Italy and Spain, experienced some of the largest growth rates in economic scientific output. Other European countries, namely the UK, Norway, the Netherlands, Denmark, and Sweden, have shown remarkable progress in per capita output. Collaborative research seems to be a key factor explaining the relative success of some European countries, in particular when it comes to publishing in top journals, attained predominantly through international collaborations.

How does monetary policy change? evidence on inflation targeting countries

We examine the evolution of monetary policy rules in a group of inflation targeting countries (Australia, Canada, New Zealand, Sweden and the United Kingdom) applying moment- based estimator at time-varying parameter model with endogenous regressors. Using this novel flexible framework, our main findings are threefold. First, monetary policy rules change gradually pointing to the importance of applying time-varying estimation framework. Second, the interest rate smoothing parameter is much lower that what previous time-invariant estimates of policy rules typically report. External factors matter for all countries, albeit the importance of exchange rate diminishes after the adoption of inflation targeting. Third, the response of interest rates on inflation is particularly strong during the periods, when central bankers want to break the record of high inflation such as in the U.K. or in Australia at the beginning of 1980s. Contrary to common wisdom, the response becomes less aggressive after the adoption of inflation targeting suggesting the positive effect of this regime on anchoring inflation expectations. This result is supported by our finding that inflation persistence as well as policy neutral rate typically decreased after the adoption of inflation targeting.

Monetary policy rules and financial stress: does financial instability matter for monetary

We examine whether and how main central banks responded to episodes of financial stress over the last three decades. We employ a new methodology for monetary policy rules estimation, which allows for time-varying response coefficients as well as corrects for endogeneity. This flexible framework applied to the U.S., U.K., Australia, Canada and Sweden together with a new financial stress dataset developed by the International Monetary Fund allows not only testing whether the central banks responded to financial stress but also detects the periods and type of stress that were the most worrying for monetary authorities and to quantify the intensity of policy response. Our findings suggest that central banks often change policy

The Öresund region: A dynamic region in Europe due to inter-regional collaboration?

El cluster Medicon Valley es troba a la regió d'Oresund binacional que s'estén per Dinamarca i Suècia, inclosa la Universitat de Lund, ciutat i tercera ciutat més gran de Suècia, Malmö (veure figura 1). El 2000, aquestes dues parts nacionals estaven connectades físicament per l'establiment dels 18 quilòmetres de longitud, enllaç fix del Øresund (ponts i túnels).

Avaluació del projecte "Nightingale/Rossinyol": projecte de mentoria amb estudiants universitaris adreçat a alumnes d'origen estranger

La recerca que aquí es presenta es centra en tres objectius. Primerament, obtenir informació d’altres experiències de mentoria d’alumnat immigrat desenvolupades en altres països (Alemanya, Àustria, Eslovènia, Estats Units, Israel, Noruega, Suècia, Suïssa, etc.) amb l’objectiu d’elaborar un marc teòric sòlid que ajudi a argumentar científicament el projecte "Rossinyol". Aquest objectiu s’ha treballat mitjançant la recerca bibliogràfica i documental a nivell nacional, estatal i internacional. Posteriorment, realitzar una primera anàlisi dels ímputs que aporta el projecte Rossinyol al territori on es porta a terme. Mitjançant l’elaboració i passi d’una entrevista a mentors, mestres (dels mentorats) i enllaços territorials (persones del territori que es posen en contacte amb les escoles per seleccionar els mentorats –entre d’altres tasques-) s’ha analitzat: els punts forts i febles del projecte, els possibles efectes de la mentoria en el mentorat i el tipus de relacions que s’han establert entre els agents que participen en el projecte. Finalment, establir uns criteris d’avaluació que permetin donar pautes per desenvolupar aquest projecte –o projectes similars de mentoria- en altres llocs del nostre país. En aquest apartat del treball s’ha elaborat una proposta d’indicadors amb el conseqüent instrument per, en una fase posterior, recollir informació que permetin fer un seguiment acurat, objectiu i extens del projecte.

Launching prices for new pharmaceuticals in heavily regulated and subsidized markets

This paper provides empirical evidence on the explanatory factorsaffecting introductory prices of new pharmaceuticals in a heavilyregulated and highly subsidized market. We collect a data setconsisting of all new chemical entities launched in Spain between1997 and 2005, and model launching prices. We found that, unlike inthe US and Sweden, therapeutically "innovative" products are notoverpriced relative to "imitative" ones. Price setting is mainly used asa mechanism to adjust for inflation independently of the degree ofinnovation. The drugs that enter through the centralized EMAapproval procedure are overpriced, which may be a consequence ofmarket globalization and international price setting.

Determining underlying macroeconomic fundamentals during emerging market crises: Are conditions as bad as they seem?

Emerging market crises are characterized by large swings in both macroeconomic fundamentalsand asset prices. The economic significance of observed movements in macroeconomicvariables is obscured by the brief and extreme nature of crises. In this paper we propose to study the macroeconomic consequences of crises by studying the behavior of effective fundamentals, constructed by studying the relative movements of stock prices during crises. We find that these effective fundamentals provide a different picture than that implied by observed fundamentals. First, asset prices often reflect expectations of improvement in fundamentals after the initial devaluations; specifically, effective depreciations are positive but not as large as the observed ones. Second, crises vary in their effect on credit market conditions, with investors expecting tightening of credit in some cases (Mexico 1994, Philippines 1997), but loosening of credit in others (Sweden 1992, Korea 1997, Brazil 1999).

A multilevel analysis on the determinants of regional health care expenditure. A note

We apply a multilevel hierarchical model to explore whether anaggregation fallacy exists in estimating the income elasticity of healthexpenditure by ignoring the regional composition of national healthexpenditure figures. We use data for 110 regions in eight OECD countriesin 1997: Australia, Canada, France, Germany, Italy, Spain, Sweden andUnited Kingdom. In doing this we have tried to identify two sources ofrandom variation: within countries and between-countries. Our resultsshow that: 1- Variability between countries amounts to (SD) 0.5433, andjust 13% of that can be attributed to income elasticity and the remaining87% to autonomous health expenditure; 2- Within countries, variabilityamounts to (SD) 1.0249; and 3- The intra-class correlation is 0.5300. Weconclude that we have to take into account the degree of fiscaldecentralisation within countries in estimating income elasticity ofhealth expenditure. Two reasons lie behind this: a) where there isdecentralisation to the regions, policies aimed at emulating diversitytend to increase national health care expenditure; and b) without fiscaldecentralisation, central monitoring of finance tends to reduce regionaldiversity and therefore decrease national health expenditure.
