Language knowledge and earnings in Catalonia

In this paper we are aimed to investigate the relationship between Catalan knowledge and individual earnings in Catalonia. Using data from 2006, we find a positive earning return to Catalan proficiency; however, when accounting for self-selection into Catalan knowledge, we find a higher language return (20% of extra earnings), suggesting that individuals who are more prone to know Catalan are also less remunerated than others (negative selection effect). Moreover, we also find important complementarities between language knowledge and completed education, which means that only more educated individuals benefit from Catalan knowledge.

Language knowledge and earnings in Catalonia

This paper investigates the economic value of Catalan knowledge for national and foreign first- and second-generation immigrants in Catalonia. Specifically, drawing on data from the “Survey on Living Conditions and Habits of the Catalan Population (2006)”, we want to quantify the expected earnings differential between individuals who are proficient in Catalan and those who are not, taking into account the potential endogeneity between knowledge of Catalan and earnings. The results indicate the existence of a positive return to knowledge of Catalan, with a 7.5% increase in earnings estimated by OLS; however, when we account for the presence of endogeneity, monthly earnings are around 18% higher for individuals who are able to speak and write Catalan. However, we also find that language and education are complementary inputs for generating earnings in Catalonia, given that knowledge of Catalan increases monthly earnings only for more educated individuals.

Knowledge of Catalan, public/private sector choice and earnings: Evidence from a double sample selection model

This paper explores the earnings return to Catalan knowledge for public and private workers in Catalonia. In doing so, we allow for a double simultaneous selection process. We consider, on the one hand, the non-random allocation of workers into one sector or another, and on the other, the potential self-selection into Catalan proficiency. In addition, when correcting the earnings equations, we take into account the correlation between the two selectivity rules. Our findings suggest that the apparent higher language return for public sector workers is entirely accounted for by selection effects, whereas knowledge of Catalan has a significant positive return in the private sector, which is somewhat higher when the selection processes are taken into account.

Teacher strategies to elicit knowledge from students in the CLIL classroom: the purpose of questions in controlled patterns of teacher-student interaction

This Master Dissertation comprises two parts: a personal reflection and an empirical study. The personal reflection reviews the process of professionalization undergone by its author throughout the Master. The empirical study tackles teacher strategies to elicit knowledge from students in the CLIL classroom and more specifically the purpose of questions in controlled patterns of teacher-student interaction. The theories of relevant authors such as Vigotsky, Mercer and Tsui are used as a framework to analyze the data presented. The analysis shows the different strategies to elicit knowledge used by the teacher and the appropriateness of her questions in the analyzed interaction

Disseny d'un pla docent d'acord amb la filosofia ECTS per a la titulació de Nutrició humana i dietètica (Matèria Bromatologia i tecnologia dels aliments)

El projecte s’ha desenvolupat, en quatre etapes: a) recollida de dades: competències professionals, característiques de la titulació en diferents universitats i tasses d’èxit avaluacions dels estudiants; b) anàlisi i reflexió sobre la informació recollida; c) realització d’una enquesta als diferents entorns professionals i sobre les millores que, a títol experimental, s’han introduït durant aquest període, en la docència i d) formulació d’una proposta de pla docent. Cal dir que superada la meitat de la durada del projecte, es va fer pública la fitxa corresponent a la titulació i per tant els seus criteris i indicacions ja s’han inclòs en la proposta. Quan als tres primers apartats i com a aspectes mes destacables, s’observa: dificultat per configurar l’ensenyament atesa la seva dualitat individu – aliment, l’existència d’un cert grau de discrepància quant a continguts, entre les propostes del professorat i els interessos analitzats des dels àmbits professionals, en funció de l’àrea de treball. D’altra banda, i ja concretament en relació amb la matèria analitzada (Bromatologia i Tecnologia dels aliments), s’observa una evident inadequació de la distribució de la matèria en assignatures en el vigent pla d’estudis, tant pel que fa a la seva ubicació temporal com d’alguns dels seus continguts. Quan a l’apartat d), es proposen els següents aspectes de tipus general: definir 4 blocs temàtics (química i bioquímica dels aliments, bases de tecnologia dels aliments, control d’aliments, integració i descriptiva d’aliments). Amb aquests blocs, s’haurien de poder configurar alguna/es assignatura/es, fins i tot conjuntament amb blocs generats a partir d’altres mòduls. Es proposen competències a assolir per a cadascun, metodologies docents aplicables i també, el disseny d’activitats de treball individual o en grup. Quant a les pràctiques, s’han de centrar especialment en el bloc corresponent al control de qualitat d’aliments, a un nivell adequat per als objectius de la titulació.

On finite unions and finite products with the D-property

We show that the product of a subparacompact C-scattered space and a Lindelöf D-space is D. In addition, we show that every regular locally D-space which is the union of a finite collection of subparacompact spaces and metacompact spaces has the D-property. Also, we extend this result from the class of locally D-spaces to the wider class of D-scattered spaces. All the results are shown in a direct way.

Entorns col•laboratius virtuals asíncrons basats en Web i enfocats en la gestió del coneixement = Web-based Asynchronous Collaborative Environments Focused on Knowledge Management

Report for the scientific sojourn at the University of California at Berkeley, USA, from september 2007 until july 2008. Communities of Learning Practice is an innovative paradigm focused on providing appropriate technological support to both formal and especially informal learning groups who are chiefly formed by non-technical people and who lack of the necessary resources to acquire such systems. Typically, students who are often separated by geography and/or time have the need to meet each other after classes in small study groups to carry out specific learning activities assigned during the formal learning process. However, the lack of suitable and available groupware applications makes it difficult for these groups of learners to collaborate and achieve their specific learning goals. In addition, the lack of democratic decision-making mechanisms is a main handicap to substitute the central authority of knowledge presented in formal learning.

Environmental Tax on Products and Services Based on Their Carbon Footprint: A Case Study of the Pulp and Paper Sector

The main aim of this work is to define an environmental tax on products and services based on their carbon footprint. We examine the relevance of conventional life cycle analysis (LCA) and environmentally extended input-output analysis (EIO) as methodological tools to identify emission intensities of products and services on which the tax is based. The short-term price effects of the tax and the policy implications of considering non-GHG are also analyzed. The results from the specific case study on pulp production show that the environmental tax rate based on the LCA approach (1,8%) is higher than both EIO approaches (0,8% for product and 1,4% for industry approach), but they are comparable. Even though LCA is more product specific and provides detailed analysis, EIO would be the more relevant approach to apply economy wide environmental tax. When the environmental tax considers non-GHG emissions instead of only CO2, sectors such as agriculture, mining of coal and extraction of peat, and food exhibit higher environmental tax and price effects. Therefore, it is worthwhile for policy makers to pay attention on the implication of considering only CO2 tax or GHG emissions tax in order for such a policy measure to be effective and meaningful. Keywords: Environmental tax; Life cycle analysis; Environmental input-output analysis.
