Aquest estudi té com a objectiu principal analitzar les transformacions que s'esdevenen al voltant de la incorporació d'innovacions tecnològiques de l'entorn de les TIC en els processos d'atenció al ciutadà per part de les administracions públiques. Les transformacions que hem analitzat tenen a veure amb tres dimensions que hem considerat bàsiques. D'una banda, ens hem centrat en els canvis que es produeixen en la forma en què els ciutadans (com a principals, tot i que no únics, usuaris) i l'administració es relacionen entre sí. De l'altra hem analitzat les transformacions que s'esdevenen en el funcionament intern i en la pròpia organització de l'administració arran de les transformacions dels canals de comunicació amb els usuaris. Per últim, hem considerat els canvis en la forma de gestionar (dissenyar, planificar, organitzar i dur a terme) el canvi i la innovació, tenint en compte especialment els rols dels diferents actors (no només públics) que hi participen. La recerca es recolza en un ampli estudi empíric sobre la Generalitat de Catalunya i en un estudi compartiu internacional sobre el Quebec, Emillia-Romagna i Escòcia.

A compositional time series is obtained when a compositional data vector is observed atdifferent points in time. Inherently, then, a compositional time series is a multivariatetime series with important constraints on the variables observed at any instance in time.Although this type of data frequently occurs in situations of real practical interest, atrawl through the statistical literature reveals that research in the field is very much in itsinfancy and that many theoretical and empirical issues still remain to be addressed. Anyappropriate statistical methodology for the analysis of compositional time series musttake into account the constraints which are not allowed for by the usual statisticaltechniques available for analysing multivariate time series. One general approach toanalyzing compositional time series consists in the application of an initial transform tobreak the positive and unit sum constraints, followed by the analysis of the transformedtime series using multivariate ARIMA models. In this paper we discuss the use of theadditive log-ratio, centred log-ratio and isometric log-ratio transforms. We also presentresults from an empirical study designed to explore how the selection of the initialtransform affects subsequent multivariate ARIMA modelling as well as the quality ofthe forecasts

The comparative analysis of air quality control policies provides an interesting field for studies of comparative policy analysis including program formulation and implementation processes. In European countries, the problem is comparable, whereas implementation structures, programs and policy impacts vary to a considerable extent. Analysis testing possibilities and constraints of air control policies under varying conditions are likely to contribute to a further development of a theory of policy analysis. This paper presents the analytical framework applied in a continuing empirical study explaining program formulation and implementation processes with respect to the different actors involved. Concrete emitter behavior can be explained by interaction processes at the very local level, by program elements of national legislation, and by structural constraints under which such programs are produced.

An alternative socio-ecological strategy? International Trade Unions' engagement with climate change
Resumo:
In the context of a global ecological crisis, it is an important move when trade unions turn to environmentalism. Yet, the form that this environmentalism takes is often overlooked. This is especially the case with international trade unions. Based on an empirical study of international trade unions' engagement with the climate change issue, this article argues that international trade unions follow three different (and partially conflicting) strategies. I label these strategies as 'deliberative', 'collaborative growth' and 'socialist', and I examine each in turn. I argue that such analysis is important if we want to identify the potential for transforming the social relations of production that are at the root of the current climate crisis, and for identifying an alternative socio-ecological strategy.

This article analyzes if, and to what extent, the public service motivation (PSM) construct has an added value to explain work motivation in the public sector. In order to address the specificity of PSM when studying work motivation, the theoretical model underlying this empirical study compares PSM with two other explanatory factors: material incentives, such as performance-related pay, and team relations and support, such as recognition by superiors. This theoretical model is then tested with data collected in a national survey of 3,754 civil servants at the Swiss municipal level. Results of a structural equations model clearly show the relevance of PSM. They also provide evidence for the importance of socio-relational motivating factors, whereas material incentives play an anecdotal role.

DIC.CAT es centra en les contribucions a la ciutadania que realitzen les dones immigrants marroquines, sobre les quals recauen forts estereotips i imatges que, sovint, les vinculen a la passivitat i a la submissió. Partint d'aquest fet, el projecte analitza el paper d'aquetes dones com a generadores de noves formes de ciutadania a Catalunya, a partir de les seves accions en les esferes pública i privada. El projecte contribueix, d'una banda a ampliar el coneixement teòric sobre la noció de ciutadania, incorporant la dimensió del gènere i partint de la realitat multicultural actual; i de l'altra a aprofundir sobre el rol que estan exercint les doens marroquines estudiades, com agents actius de xsocialització i generadores de canvis en els formes d'exercir la ciutadania en la societat catalana. Destaquen les accions que desenvolupen des de la seva quotidianitat en relació a aspectes com el procés de reagrupació, la incorporació al mercat laboral, la transmissio de valores dins la familia, la relació amb la comunitat d'origen, les motivacions, aspiracions o els projectes professionals i personals propis. Alhora, el projecte vincula aquestes accions amb les que desenvolupen des dels espais públics en els que participen, especialment dins l'àmbit associatiu.

In this article, we present the current state of our work on a linguistically-motivated model for automatic summarization of medical articles in Spanish. The model takes into account the results of an empirical study which reveals that, on the one hand, domain-specific summarization criteria can often be derived from the summaries of domain specialists, and, on the other hand, adequate summarization strategies must be multidimensional, i.e., cover various types of linguistic clues. We take into account the textual, lexical, discursive, syntactic and communicative dimensions. This is novel in the field of summarization. The experiments carried out so far indicate that our model is suitable to provide high quality summarizations.

Unlike classical theoretical expectations, our empirical study shows that financial transfers to decentralised governments increase local public expenditures much more than would be triggered by an equivalent rise in local income. This empirical evidence of the presence of a flypaper effect is achieved using panel data from 375 municipalities located in the Swiss canton of Vaud covering the period 1994 to 2005. During that time there was a major change in the financial equalisation scheme. Furthermore, our study confirms the analysis of the public choice theory: the effect depends partly on the degree of complexity of the municipal bureaucracy. These results show that local bureaucratic behaviour may impede the effectiveness of a financial equalisation scheme that aims to reduce disparities in local tax.

A qualidade nas organizações de serviço tem-se tornado num tópico de muita importância, sendo reconhecida como uma variável estratégica para aumentar a sua eficácia e eficiência, ganhar vantagem competitiva e conduzir à satisfação dos seus clientes. Promover uma escala apropriada, que reflicta convenientemente as percepções e as expectativas dos clientes, deve ser uma preocupação tanto dos gestores de empresas como das agências governativas. O presente estudo empírico desenvolve e analisa uma escala de medição da qualidade de serviço, através da aplicação do modelo SERVQUAL, desenvolvido por Parasuraman et al. (1985, 1988, 1991), e adaptado para o serviço de transporte colectivo urbano de passageiros (TCUP). O procedimento levado a efeito na presente investigação apresenta 4 fases e 9 etapas, com a combinação do paradigma de Churchill (1979) e entrevistas focus group. A escala final SERVQUAL adaptada, com 23 itens, e as dimensões obtidas indicam que a mesma é altamente fiável (0,891) e válida, demonstrando assim que o procedimento seguido é aplicável e que os seus itens foram desenhados de acordo com as condições do sector. A pesquisa exploratória foi conduzida em Cabo Verde, na cidade da Praia, em Setembro de 2008, com 230 utentes regulares do serviço de TCUP. Os dados confirmam a existência de gaps, encontrando-se a maioria dos inquiridos (67%) insatisfeita com esse serviço. A análise factorial confirmou a existência de cinco dimensões, que determinam a qualidade de serviço no TCUP, na Praia, pela seguinte ordem de importância: “aparência física dos veículos/conforto”, “atenção personalizada/desempenho dos colaboradores”, “empatia”, “conveniência do serviço”, e, por último, “equipamento tangível”. Service quality has become a topic of great importance and it is recognized as a strategic variable to increase its efficiency and effectiveness in getting competitive advantage and leading to customer satisfaction. To seek a proper scale that can reflect perceptions and customers’ expectations accurately should be a concern for business managers as well as government agencies. Present empirical study develops and analyzes a measurement scale of quality service, through the application of SERVQUAL model developed by Parasuraman et al. (1985, 1988, 1991) and adapted for the urban passenger transportation. The procedure followed in present research indicates four phases and nine steps in connection to Churchill paradigm (1979) and focus group interview. The adapted final SERVQUAL scale, with 23 items, and the dimensions obtained indicated that it is highly reliable (0.891) and valid, showing this way that the procedure followed is applicable and their items were drawn according to the sector conditions. This exploratory research was performed in Cape Verde, at Praia in September 2008 with 230 regular’s users of bus service. The data confirms the existence of gaps and that the majority of the inquired are not pleased (67%) with their bus service. The factorial analysis confirms the existence of five dimensions, which determines the service quality in the bus service at Praia according to the following order of importance : “physical appearance of the bus/confort”, “personalized attention/results from the collaborators”, “empathy”, “service convenience” and lastly “tangible equipment”.

The websites are becoming the firms’ first contact interface with their clients. Hence, understanding customers’ online attitudes and behaviors have been capturing increased research attention. The extant research has pointed customers’ satisfaction with the websites as the main reason for customers’ online behaviors. This research has used mostly variables related to the characteristics of the websites as the predictors of customers’ website satisfaction. However, recent research shows that groups of individuals displaying distinctive characteristics react differently to the same context. Therefore, behavior may be considerably different among groups of customers. In this study, we develop a conceptual model of the influence of individual characteristics on the traditional website quality – website satisfaction relationship. We propose a model based on the construct of consumer technology attractiveness (CTA) to represent the genuine positive propensity of individuals toward technology. We further test the moderating effect of this construct on the commonly used predictors of customer’s website satisfaction using Hierarchical Multiple Regression. The empirical study was based on websites of banks operating in Portuguese market. The commercial banking industry is one of the Portuguese industries that better uses the Internet to establish relationships with clients. Data were collected through an online website satisfaction survey, participated by the lecturers and postgraduate students from four Portuguese Universities and Polytechnic Institutes. Our final sample comprised 276 valid questionnaires. Our study permits to conclude that the most commonly used antecedents of website overall satisfaction are still relevant for analyzing consumer’s satisfaction with the banks websites. We also conclude that CTA has a significant moderating effect on almost all customers’ website satisfaction variables used in the study. This study contributes to highlight the theoretical importance and significant influence of consumers’ personal characteristics on their online behavior. Moreover, for the practitioners, a better understanding of these individual characteristics will assist them in developing customized websites that will meet customers’ expectations. O estudo dos comportamentos dos consumidores em ambientes online tem vindo a ter um crescente interesse, uma vez que os websites estão a transformar-se num importante ponto de contacto entre as empresas e os seus clientes. A satisfação dos clientes com os websites tem sido apontada pela Literatura como o principal condicionante dos comportamentos online dos consumidores. No entanto, a investigação científica tem conseguido provar que grupos de indivíduos com características distintas reagem de forma diferente quando submetidos a contextos idênticos, o que poderá levar a diferenças significativas no comportamento online de consumidores pertencentes a diferentes grupos. Neste estudo desenvolvemos um modelo conceptual que reflecte a influência de características individuais na relação entre a qualidade e a satisfação com os websites. Propomos um modelo assente na atractividade tecnológica do consumidor (CTA), que representa a propensão genuína que os indivíduos possuem em relação à tecnologia. Testamos o efeito moderador deste conceito sobre as variáveis mais utilizadas nos estudos sobre a satisfação dos consumidores com os websites, utilizando a Regressão Múltipla Hierárquica. O estudo empírico baseou-se nos websites dos bancos que operam no mercado português, uma vez que este sector é um dos que melhor utiliza a Internet na sua relação com os clientes. Os dados foram recolhidos através de um questionário sobre satisfação com os websites, colocado online e dirigido a docentes e estudantes de programas de pós-graduações, mestrados e doutoramentos de quatro universidades e instituto politécnico portugueses, tendo resultado numa amostra final de 276 questionários validados estatisticamente. Este estudo permitiu concluir que as variáveis que são mais utilizadas como antecedentes da satisfação dos consumidores com os websites, continuam a ser igualmente válidas para a análise dos websites dos bancos. Também concluímos que a CTA tem efeitos moderadores significativos na grande maioria das variáveis utilizadas neste estudo. Assim, conseguimos realçar a importância teórica das características pessoais dos consumidores no seu comportamento online. Para os gestores, uma melhor compreensão destas características individuais permitir-lhes-á desenvolver websites customizados que irão satisfazer as expectativas dos seus clientes.

Highly competitive environments are leading companies to implement SupplyChain Management (SCM) to improve performance and gain a competitiveadvantage. SCM involves integration, co-ordination and collaborationacross organisations and throughout the supply chain. It means that SCMrequires internal (intraorganisational) and external (interorganisational)integration. This paper examines the Logistics-Production and Logistics-Marketing interfaces and their relation with the external integrationprocess. The study also investigates the causal impact of these internaland external relationships on the company s logistical service performance.To analyse this, an empirical study was conducted in the Spanish Fast MovingConsumer Goods (FMCG) sector.

In the fixed design regression model, additional weights areconsidered for the Nadaraya--Watson and Gasser--M\"uller kernel estimators.We study their asymptotic behavior and the relationships between new andclassical estimators. For a simple family of weights, and considering theIMSE as global loss criterion, we show some possible theoretical advantages.An empirical study illustrates the performance of the weighted estimatorsin finite samples.

Adversarial relationships have long dominated business relationships,but Supply Chain Management (SCM) entails a new perspective. SCM requiresa movement away from arms-length relationships toward partnership stylerelations. SCM involves integration, co-ordination and collaborationacross organisations and throughout the supply chain. It means that SCMrequires internal (intraorganisational) and external (interorganisational)integration. This paper analyses the relationship between internal andexternal integration processes, their effect on firms performance andtheir contribution to the achievement of a competitive advantage.Performance improvements are analysed through costs, stock out and leadtime reductions. And, the achievement of a better competitive positionis measured by comparing the firm s performance with its competitors performance. To analyse this, an empirical study has been conducted inthe Spanish grocery sector.
