A Framework for Analyzing Language and Welfare

The paper proposes a general model that will encompass trade and social benefits of a common language, a preference for a variety of languages, the fundamental role of translators, an emotional attachment to maternal language, and the threat that globalization poses to the vast majority of languages. With respect to people’s emotional attachment, the model considers minorities to suffer losses from the subordinate status of their language. In addition, the model treats the threat to minority language as coming from the failure of the parents in the minority to transmit their maternal language (durably) to their children. Some familiar results occur. In particular, we encounter the usual social inefficiencies of decentralized solutions to language learning when the sole benefits of the learning are communicative benefits (though translation intervenes). However, these social inefficiencies assume a totally different air when the con-sumer gains of variety are brought in. One fundamental aim of the paper is to bring together contributions to the economics of language from labor economics, network externalities and international trade that are typically treated separately.

(No)competition in the Spanish retailing gasoline market: a variance filter approach

Various methodologies in economic literature have been used to analyse the international hydrocarbon retail sector. Nevertheless at a Spanish level these studies are much more recent and most conclude that generally there is no effective competition present in this market, regardless of the approach used. In this paper, in order to analyse the price levels in the Spanish petrol market, our starting hypothesis is that in uncompetitive markets the prices are higher and the standard deviation is lower. We use weekly retail petrol price data from the ten biggest Spanish cities, and apply Markov chains to fill the missing values for petrol 95 and diesel, and we also employ a variance filter. We conclude that this market demonstrates reduced price dispersion, regardless of brand or city.

Estimació de les emissions de metà generades per fermentació entèrica a la ramaderia bovina a Catalunya, com a font de gasos d'efecte hivernacle (GEH)

L’emissió de GEH generats per processos relacionats amb l’activitat antropogènica ha provocat que la temperatura mitjana de la Terra augmenti, originant el que es coneix com escalfament global. Les possibles conseqüències negatives per al conjunt de la biosfera han portat a l’adopció d’acords internacionals que obliguen als diferents Estats a realitzar Inventaris Nacionals d’Emissions a l’Atmosfera. El CH4, que és exhalat o eructat com a resultat del procés de fermentació entèrica dels remugants, genera un impacte que ha de ser quantificat en els diferents inventaris. En aquest projecte s’ha realitzat l’estimació del CH4 generat per la fermentació entèrica dels bovins a Catalunya. Per aquest objectiu s’han utilitat les equacions explicitades a les directrius del Panel Intergovernamental sobre el Canvi Climàtic (IPCC), així com l’equació de Cambra, L. et al. (2008) per a la determinació del factor de conversió Ym. El resultat final rebaixa les quantitats inventariades tant per l’administració catalana com per l’espanyola.

Spanish pension system: population aging and immigration policy

There is a widespread consensus in the literature that, as consequence of the demographic transition, the current Spanish pension system will become unsustainable in the next decades. In this article we evaluate the sustainability of the contributory pensions' sub-system, taking into account the demographic projections by the Spanish Statistical Office (INE). A baseline scenario is projected as well as several reforms are simulated, focusing on: (i) selective immigration policy, (ii) changes in the way of setting the pensions and (iii) increase of the legal age of retirement up to 68. The main results are the following. The current system would not incur deficits until 2018, from then deficits will begin to be accumulated. The expenditure in pensions practically would double (from 8.3 % in 2005 to 17.2 % in 2050). A selective immigration policy -towards foreign young people- would help, but does not solve the long-term sustainability of the current system. A policy that combines a pensions' growth at a pace lower than productivity growth and extends the legal age of retirement up to 68 would give solvency to the system beyond 2029

English as a Global Language

How far has English already spread? How much further can we expect it to go? In response to the first question, this chapter tries to identify the areas of life where English already serves as a lingua franca in the world (more or less) and those where the language faces sharp competition and does not threaten to marginalize the other major languages. The former areas of life are international safety, the internal business of international organizations, internal communication within the international news industry, international sports and science. The latter areas are the press, television, the internet, publishing and international trade. As to the second question, about the future prospects of English, the chapter argues that the advance of English will depend heavily on the motives to learn the other major languages in the world as well. Based on the empirical evidence, the same model applies to the incentives to learn English and these other languages. On the important topic of welfare, the cultural market is the single one where it is arguable that the progress of English has gone too far. English dominance in the song, the cinema and the best-seller is indeed extraordinary and difficult to reconcile with the evidence popular attachments to home languages, which is otherwise strong and apparent.

Agronomic and commercial performance of four Spanish carob cultivars

The carob tree (Ceratonia siliqua) shows interesting prospects for some coastal Mediterranean growing areas and is widely used for industrial, agricultural, and ornamental purposes. It can be an alternative crop adapted to part-time farming and can also be used to regenerate vegetation in areas with a mild climate and erosion problems. Four Spanish carob cultivars were examined (Banya de Cabra, Duraio, Matalafera, and Rojal) to determine the one that performed the best for planting new orchards in northeastern Spain (Catalonia). The trees in this rain-fed trial (average rainfall of 500 mm) were planted in 1986 using seedling rootstocks that were budded in 1987. The trees were trained using the free-vase system and were spaced 8 x 9 m (138 trees/ha including 12% pollinators). The results showed that ‘Rojal’ was the earliest bearing cultivar. However, no significant differences were observed for cumulative pod production 18 years after budding. With respect to cumulative seed yield, ‘Duraio’ had the highest production (95 kg/tree). The lowest tree vigor (trunk cross-section) was observed in ‘Matalafera’. ‘Rojal’ trees produced the largest pods (average fruit weight of 18.9 g) and lowest seed content (11.8%), while ‘Banya de Cabra’ and ‘Duraio’ produced the smallest fruit (weighing 15.3 and 16.2 g, respectively) with the highest seed content (15.2% and 17.3%, respectively). Gum content, expressed as a percentage of the dry weight, was highest in ‘Duraio’ (56.9%) and was lowest in ‘Rojal’ (54.1%). Thus, in terms of kernel and pod production, ‘Duraio’ appeared to be the best-performing female cultivar for planting new carob orchards

High-throughput hydrophilic interaction chromatography coupled to tandem mass spectrometry for the optimized quantification of the anti-Gram-negatives antibiotic colistin A/B and its pro-drug colistimethate.

Colistin is a last resort's antibacterial treatment in critically ill patients with multi-drug resistant Gram-negative infections. As appropriate colistin exposure is the key for maximizing efficacy while minimizing toxicity, individualized dosing optimization guided by therapeutic drug monitoring is a top clinical priority. Objective of the present work was to develop a rapid and robust HPLC-MS/MS assay for quantification of colistin plasma concentrations. This novel methodology validated according to international standards simultaneously quantifies the microbiologically active compounds colistin A and B, plus the pro-drug colistin methanesulfonate (colistimethate, CMS). 96-well micro-Elution SPE on Oasis Hydrophilic-Lipophilic-Balanced (HLB) followed by direct analysis by Hydrophilic Interaction Liquid Chromatography (HILIC) with Ethylene Bridged Hybrid - BEH - Amide phase column coupled to tandem mass spectrometry allows a high-throughput with no significant matrix effect. The technique is highly sensitive (limit of quantification 0.014 and 0.006μg/mL for colistin A and B), precise (intra-/inter-assay CV 0.6-8.4%) and accurate (intra-/inter-assay deviation from nominal concentrations -4.4 to +6.3%) over the clinically relevant analytical range 0.05-20μg/mL. Colistin A and B in plasma and whole blood samples are reliably quantified over 48h at room temperature and at +4°C (<6% deviation from nominal values) and after three freeze-thaw cycles. Colistimethate acidic hydrolysis (1M H2SO4) to colistin A and B in plasma was completed in vitro after 15min of sonication while the pro-drug hydrolyzed spontaneously in plasma ex vivo after 4h at room temperature: this information is of utmost importance for interpretation of analytical results. Quantification is precise and accurate when using serum, citrated or EDTA plasma as biological matrix, while use of heparin plasma is not appropriate. This new analytical technique providing optimized quantification in real-life conditions of the microbiologically active compounds colistin A and B offers a highly efficient tool for routine therapeutic drug monitoring aimed at individualizing drug dosing against life-threatening infections.

Women at home, at school and in the factory. The particular discourse of domesticity done by the Spanish Escuela Economista (1861-1909)

The texts by the Spanish Economist School (second half of the 19th century) contain an assessment of the role of women in the economy and society that is transgressor in front of the prevailing discourse that defended a unique and exclusive role for all women: being at home and a mother. Most members of that economic trend defended female work in the factories, basing themselves on wage arguments and even asked for a professional training for those who in many cases could not even write and read for the fact of being a woman. The texts of those economists give new ideas about the economic and social role of women in a Spain dominated by a discourse that denied the necessity of female work for the working families.

El català, llengua d'oci en els joves

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. Aquest treball de recerca consisteix en una anàlisi de la llengua catalana en l'àmbit de l'oci en els joves. Fent aquesta anàlisi es pretén arribar a saber quina llengua predomina en l'ús dels joves quan escolten música, llegeixen, miren la televisió, juguen amb els amics, naveguen per internet, etc.,també es vol obtenir resultats fiables per saber la situació de la llengua catalana en l'oci d'aquests joves així com les causes i les variables d'aquesta situació. A partir d'unes 173 enquestes realitzades al curs de 2n de batxillerat de l'IES Antoni de Martí i Franquès, s'ha pogut dur a terme aquest estudi. Per fer aquest treball, en primer lloc es va procedir a la lectura de bibliografia relacionada amb la sociolingüística catalana. Després es va analitzar el concepte d'oci, i es va formular una enquesta que pogués resoldre els objectius. Un cop fetes les 173 enquestes se'n van codificar i tractar els resultats. A partir de les dades es van fer uns gràfics tot analitzant-les i així veure la situació real de la llengua catalana. També es va comparar aquest treball amb un altre estudi anterior realitzat per l'Institut de sociolingüística catalana. I després d'haver parlat sobre la situació de la llengua catlana entre els joves amb diversos experts en el tema se'n van treure unes conclusions.

Els refranys: estudi i equivalències

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. El treball es divideix en tres grans blocs temàtics, seguint una seqüència lògica: teoria dels refranys, recull de refranys catalans i els seus equivalents (inclou la creació d un diccionari) i l’aplicació pràctica del treball en un lloc web. Dins del bloc teòric es tracten amb profunditat àmbits de la fraseologia i la paremiologia (ciència dels refranys i les unitats fraseològiques) com ara la formació dels refranys, la seva estructura, el seu significat i el seu ús. També s’hi inclou un criteri de comparació de refranys de llengües diferents, tenint en compte aspectes com el seu grau d idiomaticitat (possibilitat d’establir el significat d’una unitat pel seu sentit figurat i a la vegada pel seu sentit literal). Cal destacar que l’estudi teòric dels refranys és gairebé inexistent en llengua catalana, i que en conseqüència l’elaboració d’aquesta part del projecte ha requerit un esforç suplementari. En el segon bloc, partint d’un recull de refranys pertanyent al besavi de l’alumna, on hi constaven refranys catalans amb els seus equivalents en francès i castellà, s’elabora un diccionari de refranys, explicant el significat d’aquests i afegint-hi l’equivalent en anglès, i en alguns casos, fins i tot es comenta l’antecedent llatí del refrany. Per tal de trobar una dimensió pràctica al nou recull, es procedeix a la creació d’un lloc web, amb la intenció de difondre el contingut del diccionari. Aquest seria el tercer bloc que conforma el treball.

Devolution dynamics of Spanish local government

Over the last few years, ther has been a devolutionary tendency in many developed and developing countries. In this article we propose a methodology to decompose whether the benefits in terms of effciency derived from transfers of powers from higher to municipal levels of government "the "economic dividend" of devolution) might increase over time. This methodology is based on linear programming approaches for effciency measurement. We provide anapplication to Spanish municipalities, which have had to adapt to both the European Stability and Growth Pact as well as to domestic regulation seeking local governments balanced budget. Results indicate that efficiency gains from enhaced decentralization have increased over time. However, the way through which these gains accrue differs across municipalities -in some cases technical change is the main component, whereas in others catching up dominates.
