Aproximació al disseny de procediments i instruments per a la personalització de l'ensenyament a l'etapa primària des d'una perspectiva inclusiva

The main objective of this research is to found a new process about the personalization's curriculum for pupils with especial educational needs. In this research there are two objectives: the first objective is to describe a procedure for to do the individual planning for this pupils. This procedure is called "Procediment per cartes de personalització" (Pedragosa 2002). The other objective is centered to validate this procedure for teachers who are in active service in primary's etapa and to check if it's a good process for to do the individual planning in an inclusive approach. The procedure's cobcretion is about three basic referents: In the first, we consult with the current regulations, in the second we incorporate the inclusion's approach and the fundamentals of universal learning design, and finally we consult Ruiz's (1999) provides. We obtain the information for the research until, during and after of the formation's course (in 2003/2004). We introduced two questionnaire (until and after of formation sessions) and we register all of the sessions with a parlimentary report. About the main research results we can to affirm that the procedure is a good option for the professional's practice. It's an organized, ordered and coherent design with our curriculum. But, in spite of, we can to probate that there some interesting variables which are to influence to the procedure's efficiency.

Methodological note about the determination of key sectors in final energy consumption: a preliminary approach to the Spanish case

In this paper we analyze the determination of "key" sectors in the final energy consumption. We approach this issue from an input-output perspective and we design a methodology based on the elasticities of the demands of final energy consumption. As an exercise, we apply the proposed methodology to the Spanish economy. The analysis allows us to indicate the greater or lesser relevance of the different sectors in the consumption of final energy, pointing out which sectors deserve greater attention in the Spanish case and showing the implications for energy policy.

Inequality in CO2 emissions across countries and its relationship with income inequality: a distributive approach

This paper analyses the inequality in CO2 emissions across countries (and groups of countries) and the relationship of this inequality with income inequality across countries for the period (1971-1999). The research employs the tools that are usually applied in income distribution analysis. The methodology used here gives qualitative and quantitative information on some of the features of the inequalities across countries that are considered most relevant for the design and discussion of policies aimed at mitigating climate change. The paper studies the relationship between CO2 emissions and GDP and shows that income inequality across countries has been followed by an important inequality in the distribution of emissions. This inequality has diminished mildly, although the inequality in emissions across countries ordered in the increasing value of income (inequality between rich and poor countries) has diminished less than the “simple” inequality in emissions. Lastly, the paper shows that the inequality in CO2 emissions is mostly explained by the inequality between groups with different per capita income level. The importance of the inequality within groups of similar per capita income is much lower and has diminished during the period, especially in the low-middle income group.

Real equilibrium exchange rates. A panel data approach for advanced and emerging economies.

Based on an behavioral equilibrium exchange rate model, this paper examines the determinants of the real effective exchange rate and evaluates the degree of misalignment of a group of currencies since 1980. Within a panel cointegration setting, we estimate the relationship between exchange rate and a set of economic fundamentals, such as traded-nontraded productivity differentials and the stock of foreign assets. Having ascertained the variables are integrated and cointegrated, the long-run equilibrium value of the fundamentals are estimated and used to derive equilibrium exchange rates and misalignments. Although there is statistical homogeneity, some structural differences were found to exist between advanced and emerging economies.

Educació en valors i formació docent. La diversitat com a valor

La reflexió sobre la meva pràctica educativa m’ha portat a endinsar-me en el món de la diversitat i de l’educació en valors, i preguntar-me sobre la seva ubicació en la formació docent. L’enfocament d’aquestes qüestions s’ha realitzat des de l’òptica de la persona. Des d’ella s’han buscat uns eixos vertebradors mínims que haurien d’estar presents tant en tot plantejament educatiu concret, com en la legislació en matèria educativa i en els plans de formació del professorat. Aquests eixos vertebradors s’han articulat en una tipologia de valors formada pel valor de la persona, des del qual sorgeixen el valor de l’educació, els valors de la democràcia i el valor de la utopia. El que he realitzat en aquesta recerca ha estat analitzar la legislació educativa i els plans d’estudi de formació de mestres de les universitats de Catalunya a partir de quatre grups d’indicadors que pretenen l’estudi del seu marc contextual, del vocabulari utilitzat –concretament els termes “ètica”, “moral” i “valor”-, del tractament de la diversitat –a partir del territori i la classe social, l’ètnia, el gènere i les necessitats educatives especials-, i de l’enfocament de l’educació en valors –segons la tipologia anteriorment apuntada-.

A Multisectorial model of prices: the SAM approach

Social Accounting Matrices (SAM) are normally used to analyse the income generation process. They are also useful, however, for analysing the cost transmission and price formation mechanisms. For price contributions, Roland-Holst and Sancho (1995) used the SAM structure to analyse the price and cost linkages through a representation of the interdependence between activities, households and factors. This paper is a further analysis of the cost transmission mechanisms, in which I add the capital account to the endogenous components of the Roland-Holst and Sancho approach. By doing this I reflect the responses of prices to the exogenous shocks in savings and investment. I also present an additive decomposition of the global price effects into categories of interdependence that isolates the impact on price levels of shocks in the capital account. I use a 1994 Social Accounting Matrix to make an empirical application of the Catalan economy. Keywords: social accounting matrix, cost linkages, price transmission, capital account.

Income growth and atmospheric pollution in Spain: an input-output approach

The relationships between economic growth and environmental pressures are complex. Since the early nineties, the debate on these relationships has been strongly influenced by the Environmental Kuznets Curve hypothesis, which states that during the first stage of economic development environmental pressures increase as per capita income increases, but once a critical turning-point has been reached these pressures diminish as income levels continue to increase. However, to date such a delinking between economic growth and emission levels has not happened for most atmospheric pollutants in Spain. The aim of this paper is to analyse the relationship between income growth and nine atmospheric pollutants in Spain. In order to obtain empirical outcomes for this analysis, we adopt an input-output approach and use NAMEA data for the nine pollutants. First, we undertake a structural decomposition analysis for the period 1995-2000 to estimate the contribution of various factors to changes in the levels of atmospheric emissions. And second, we estimate the emissions associated with the consumption patterns of different groups of households classified according to their level of expenditure

Agglomeration and location: a nonparametric approach

The aim of this article is to assess the effects of several territorial characteristics, specifically agglomeration economies, on industrial location processes in the Spanish region of Catalonia. Theoretically, the level of agglomeration causes economies which favour the location of new establishments, but an excessive level of agglomeration might cause diseconomies, since congestion effects arise. The empirical evidence on this matter is inconclusive, probably because the models used so far are not suitable enough. We use a more flexible semiparametric specification, which allows us to study the nonlinear relationship between the different types of agglomeration levels and location processes. Our main statistical source is the REIC (Catalan Manufacturing Establishments Register), which has plant-level microdata on location of new industrial establishments. Keywords: agglomeration economies, industrial location, Generalized Additive Models, nonparametric estimation, count data models.

Xarxes virtuals de solidaritat: el cas del grup d'autoajuda Bipolarweb

Per a poder comprendre la dimensió de les possibles transformacions que Internet pot comportar, cal investigar els usos concrets de què es o ha estat objecte. En definitiva, cal realitzar investigacions empíriques que aportin informació sobre qui usa Internet, en quines circumstàncies i amb quins objectius. En aquest context, s’ha iniciat l’anàlisi en profunditat d’un cas específic de comunitat virtual de suport social creada per una persona afectada pel trastorn bipolar. L’objectiu d’una comunitat d’autoajuda virtual és proporcionar informació i recolzament emocional a través d’Internet. Mitjançant una metodologia qualitativa s’ha realitzat l’observació del fòrum virtual que penja de la pàgina web “Bipoloarweb.com”. En les investigacions del fenomen dels grups d’autoajuda a Internet, sovint s’ha destacat que a diferència dels grups ‘presencials’, aquests només poden aportar recolzament emocional i informatiu als seus membres. El tipus de recolzament instrumental o altre tipus d’assistència física, en canvi, no és possible en els casos virtuals. Els primers resultats de la recerca invaliden aquesta afirmació general ja que s’ha pogut observar episodis diferents d’ajut instrumental. En relació a la gestió d’informació i producció de coneixement, ja es pot avançar algunes qüestions interessants. En primer lloc, la quantitat i el detall de la informació que en el fòrum circula sobre el trastorn Bipolar. La majoria d’aquests coneixements, però, sorgeixen directament de compartir l’experiència diària entre els membres del grup. Tot això permet avançar la següent hipòtesi de treball pel futur: a més a més de suport emocional i instrumental, aquest grup ‘empodera’ el seus membres? Si la resposta fos positiva, el nostre cas tindria semblances amb altres fenòmens com son les associacions de malalts.

A Computable general equilibrium approach to hypothetical extractions and missing links

Identifying key sectors or key locations in an interconnected economy is of paramount importance for improving policy planning and directing economic strategy. Hence the relevance of categorizing them and hence the corresponding need of evaluating their potential synergies in terms of their global economic thrust. We explain in this paper that standard measures based on gross outputs do not and cannot capture the relevant impact due to self- imposed modeling limitations. In fact, common gross output measures will be systematically downward biased. We argue that an economy wide Computable General Equilibrium (CGE) approach provides a modeling platform that overcomes these limitations since it provides (i) a more comprehensive measure of linkages and (ii) an alternate way of accounting for links' relevance that is in consonance with standard macromagnitudes in the National Income and Product Accounts.

Non-hyperbolic boundary equilibrium bifurcations in planar Filippov systems: a case study approach

Boundary equilibrium bifurcations in piecewise smooth discontinuous systems are characterized by the collision of an equilibrium point with the discontinuity surface. Generically, these bifurcations are of codimension one, but there are scenarios where the phenomenon can be of higher codimension. Here, the possible collision of a non-hyperbolic equilibrium with the boundary in a two-parameter framework and the nonlinear phenomena associated with such collision are considered. By dealing with planar discontinuous (Filippov) systems, some of such phenomena are pointed out through specific representative cases. A methodology for obtaining the corresponding bi-parametric bifurcation sets is developed.

A Retail benchmarking approach to eficient two-way access pricing

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the marginal costs and the retail prices set by both networks. In the case of competition in linear prices, we show that there is a unique linear rule that implements the Ramsey outcome as the unique equilibrium, independently of the underlying demand conditions. In the case of competition in two-part tariffs, we consider a class of access pricing rules, similar to the optimal one under linear prices but based on average retail prices. We show that firms choose the variable price equal to the marginal cost under this class of rules. Therefore, the regulator (or the competition authority) can choose one among the rules to pursue additional objectives such as consumer surplus, network covera.

Different trajectories of exosomatic energy metabolism for Brazil, Chile and Venezuela: using the MSIASM approach

Economic development goes hand in hand with an increase in the consumption of natural resources. Some analysts use material flows to describe such relationship [Eurostat 2001, Weisz et al., 2006], or exergy [Ayres et al., 2003]. Instead this paper will use a characterisation of the exosomatic energy metabolism based on expected benchmark values to describe possible constraints to economic development posed by available human time and energy. The aim of the paper is to identify types of exosomatic energy metabolism of different societies to interpret its consequences for economic development. This is done with the application of the accounting methodology called Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) to the particular case of energy metabolism for the analysis of the economies of Brazil, Chile and Venezuela.

Generalized factor models: a bayesian approach

There is recent interest in the generalization of classical factor models in which the idiosyncratic factors are assumed to be orthogonal and there are identification restrictions on cross-sectional and time dimensions. In this study, we describe and implement a Bayesian approach to generalized factor models. A flexible framework is developed to determine the variations attributed to common and idiosyncratic factors. We also propose a unique methodology to select the (generalized) factor model that best fits a given set of data. Applying the proposed methodology to the simulated data and the foreign exchange rate data, we provide a comparative analysis between the classical and generalized factor models. We find that when there is a shift from classical to generalized, there are significant changes in the estimates of the structures of the covariance and correlation matrices while there are less dramatic changes in the estimates of the factor loadings and the variation attributed to common factors.
