Marxian insights from the mainstream

Starting in 1999 a group of papers have appeared in mainstream journals that treat of the relation between capitalism and democracy in an eminently Marxian fashion. These analyses bear on a number of papers published mainly in S&S, specifically those of Castañada, Ellman, Harnacker, Nimtz and Petras. This paper provides résumés of all of these works and then sets out the implications of the mainstream papers for the left wing ones. It concludes by emphasising the importance for the left of the mainstream results.

Immigration and Firm Growth: Evidence from Spanish cities

This article analyses the effect of immigration flows on the growth and efficiency of manufacturing firms in Spanish cities. To date, most studies have tended to focus on the effect immigrants have on labour markets at an aggregate level. Here, however, we undertake an exhaustive analysis at the firm level and report conclusive empirical findings. Ten years ago, Spain began to register massive immigration flows, concentrated above all on its most dynamic and advanced regions. Here, therefore, rather than focusing on the impact this has had on Spain’s labour market (changes to the skill structure of the workforce, increase in labour supply, the displacement of native workers, etc.), we examine the arrival of immigrants in terms of the changes this has meant to the structure of the country’s cities and their amenities. Thus, we argue that the impact of immigration on firm performance should not only be considered in terms of the labour market, but also in terms of how a city’s amenities can affect the performance of firms. Employing a panel data methodology, we show that the increasing pressure brought to bear by immigrants has a positive effect on the evolution of labour productivity and wages and a negative effect on the job evolution of these manufacturing firms. In addition, both small and new firms are more sensitive to the pressures of such immigrant inflows, while foreign market oriented firms report higher productivity levels and a less marked impact of immigration than their counterparts. In this paper, we also present a set of instruments to correct the endogeneity bias, which confirms the effect of local immigration flows on the performance of manufacturing firms.

Fiscal sustainability across government tiers

This paper analyses how fiscal adjustment comes about when both central and sub-national governments are involved in consolidation. We test sustainability of public debt with a fiscal rule for both the federal and regional government. Results for the German Länder show that lower tier governments bear a relatively smaller part of the burden of debt consolidation, if they consolidate at all. Most of the fiscal adjustment occurs via central government debt. In contrast, both the US federal and state levels contribute to consolidation of public finances.

Perfil d'un grup de penats per delictes contra la seguretat del trànsit

La recent qualificació de certs comportaments en la conducció de vehicles, amb conseqüències letals i indesitjables per a les víctimes, com a conductes delictives ha impactat de manera notable en la reducció de la freqüència i la gravetat d'aquestes conductes. La gestió i la intervenció juridicopenal amb aquests nous tipus d'infractors requereix conèixer les seves característiques individuals psicològiques i criminològiques que els fan especialment susceptibles de reincidir en el futur en aquests tipus delictius. L'objectiu d'aquest treball era avaluar les possibles diferències actitudinals i de personalitat entre un grup de condemnats per delictes contra la seguretat del trànsit, que estaven seguint una MPA, i un grup de controls. Es van seleccionar dues mostres de conductors, infractors i no-infractors, i es van avaluar mitjançant el NEO-FFI i el JI-R simultàniament. Els resultats indiquen que, respecte a les actituds antisocials, els membres del grup d'infractors mostren més actituds antisocials en general que els del grup control. Els infractors de trànsit mostren actituds antisocials compartides amb d'altres delinqüents. Tanmateix, en relació amb el segon objectiu de l'estudi, no es van detectar diferències significatives respecte a la personalitat entre els dos grups. És important ressenyar que la combinació de les mesures de personalitat i actitudinals emprades en aquest estudi permet classificar els conductors amb un bon nivell de precisió en les categories de presència/absència d'una condemna judicial per delicte de trànsit. Cal remarcar la necessitat d'un estudi més ampli i perllongat en el temps per tal de replicar aquests resultats i especialment verificar el seu efecte en la reincidència a un any, ja que en aquesta mostra no hem pogut contrastar-ho.

Perfil de un grupo de penados por delitos contra la seguridad del tráfico

Ambos grupos presentan perfiles diferentes, especialmente por lo que se refiere a las actitudes. Las implicaciones se discuten en el texto.

Anàlisi de les variables relacionades amb la reincidència dels agressors sexuals. Estudi d’una mostra d’interns de les presons de Catalunya

Les taxes de reincidència dels delinqüents sexuals son, en general més baixes que les de la resta de delinqüents. No obstant, hi ha una part que tenen una major probabilitat de tornar a delinquir i que tenen unes característiques de risc que els diferencien dels altres. S’ha dut a terme un estudi retrospectiu amb la totalitat dels delinqüents sexuals que van sortir de les presons de Catalunya entre l’1 de gener de 1998 i el 31 de desembre de 2001. El període de seguiment promig és de sis anys i nou mesos. S’han avaluat les taxes de reincidència en delictes sexuals, delictes no sexuals (generals) i en qualsevol tipus de delicte. Un 5,7 % va tornar a delinquir en delictes sexuals, el 13,2 dels subjectes va reincidir en delictes no sexuals i el 18,8 % va tornar a cometre qualsevol tipus de delicte. Entre les variables de risc, el nombre de delictes sexuals pels que compleixen condemna abans de sortir en llibertat i el tipus de víctima influeixen en la reincidència sexual, encara que respecte a la segona no es va poder calcular la significació estadística. També van tenir un pes significatiu l’edat del primer ingrés i la versatilitat delictiva. Pel que fa a la reincidència general, les variables relacionades amb la carrera delictiva i trets antisocials, a més de les condicions de la condemna, van ser les variables de més influencia. No s’ha trobat relació entre el tractament i la reincidència. Posteriorment a l’estudi d’aquestes variables van ser entrevistats vuit dels 11 subjectes que havien reincidit en delictes sexuals. A partir de l’anàlisi de les entrevistes es va elaborar un sistema de classificació dels principals components del procés del delicte. De la revisió del procés de cada subjecte apareixen dos perfils diferenciats.

Análisis de las variables relacionadas con la reincidencia de los agresores sexuales. Estudio de una muestra de internos de las prisiones de Catalunya

Estas conclusiones han de permitir en el futuro enriquecer los programas de tratamiento mediante la inclusión de contenidos y el establecimiento de criterios de individualización de la intervención.

Approaches to OER Development

OER development is becoming more sophisticated as instructors and course specialists become more familiar with the environment. Most OER development approaches for online courses have been developed from those that were appropriate in the face-to-face context. However, the OER online environment opens up new possibilities for learning as well as holding particular limitations. This paper presents some approaches that OER implementers should bear in mind when initiating and supporting OER course development projects.1. Beg, borrow, or steal courseware. Don't reinvent the wheel.2. Take what exists and build the course around it.3. Mix and match. Assemble. Don't create.4. Avoid the "not invented here" syndrome. 5. Know the content -garbage in and garbage out.6. Establish deadlines. Work to deadlines, but don't be unrealistic. 7. Estimate your costs and then double them. Double them again. 8. Be realistic in scheduling and scoping.9. The project plan must be flexible. Be prepared for major shifts.10. Build flexibly for reuse and repurposing -generalizability reduces costs 11. Provide different routes to learning. 12. Build to international standards.There are necessary features in every OER, including introduction, schedule etc. but it is most important to keep the course as simple as possible. Extreme Programming (XP) methodology can be adapted from software engineering to aid in the course development process.

Self-Development of Competences for Social Inclusion Using the TENCompetence Infrastructure

This paper describes a pilot study centred on the technology-enhanced self-development of competences in lifelong learning education carried out in the challenging context of the Association of Participants Àgora. The pilot study shows that the use of the TENCompetence infrastructure, i.e. in this case the Personal Development Planner tool, provides various kinds of benefits for adult participants with low educational profiles and who are traditionally excluded from the use of innovative learning technologies and the knowledge society. The selforganized training supported by the PDP tool aims at allowing the learners to create and control their own learning plans based on their interests and educational background including informal and non-formal experiences. In this sense, the pilot participants had the opportunity to develop and improve their competences in English language (basic and advanced levels) and ICT competence profiles which are mostly related to functional and communicative skills. Besides, the use of the PDP functionalities, such as the self-assessment, the planning and the self-regulating elements allowed the participants to develop reflective skills. Pilot results also provide indications for future developments in the field of technology support for self-organized learners. The paper introduces the context and the pilot scenario, indicates the evaluation methodology applied and discusses the most significant findings derived from the pilot study.

Collage, a Collaborative Learning Design Editor Based on Patterns

This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in elearning since it highlights the importance of social interactions as an essential element of learning. CSCL is an interdisciplinary domain, which demands participatory design techniques that allow teachers to get directly involved in design activities. Developing CSCL designs using LD is a difficult task for teachers since LD is a complex technical specification and modelling collaborative characteristics can be tricky. Collage helps teachers in the process of creating their own potentially effective collaborative Learning Designs by reusing and customizing patterns, according to the requirements of a particular learning situation. These patterns, called Collaborative Learning Flow Patterns (CLFPs), represent best practices that are repetitively used by practitioners when structuring the flow of (collaborative) learning activities. An example of an LD that can be created using Collage is illustrated in the paper. Preliminary evaluation results show that teachers, with experience in CL but without LD knowledge, can successfully design real collaborative learning experiences using Collage.

Computational Representation of Collaborative Learning Flow Patterns Using IMS Learning Design

The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed CLFPs (Collaborative Learning Flow Patterns) as a way of collecting these best practices. To facilitate the process of CLFPs by software systems, the paper proposes to specify these patterns using IMS Learning Design (IMS-LD). Thus, teachers without technical knowledge can particularize and integrate CSCL tools. Nevertheless, the support of IMS-LD for describing collaborative learning activities has some deficiencies: the collaborative tools that can be defined in these activities are limited. Thus, this paper proposes and discusses an extension to IMS-LD that enables to specify several characteristics of the use of tools that mediate collaboration. In order to obtain a Unit of Learning based on a CLFP, a three stage process is also proposed. A CLFP-based Unit of Learning example is used to illustrate the process and the need of the proposed extension.

¿Es posible reducir el gasto sanitario a través del subsidio a los seguros sanitarios privados? La doble cobertura sanitaria en Catalunya. Estimación de patrones de utilización de servicios sanitarios y simulación de costes asociados a la asistencia sanit

The objective of this study consists in quantifying in money terms the potential reduction in usage of public health care outlets associated to the tenure of double (public plus private) insurance. In order to address the problem, a probabilistic model for visits to physicians is specified and estimated using data from the Catalonian Health Survey. Also, a model for the marginal cost of a visit to a physician is estimated using data from a representative sample of fee-for-service payments from a major insurer. Combining the estimates from the two models it is possible to quantify in money terms the cost/savings of alternative policies which bear an impact on the adoption of double insurance by the population. The results suggest that the private sector absorbs an important volume of demand which would be re-directed to the public sector if consumers cease to hold double insurance.

La caverna de Josep Palau i Fabre (1952-1969): teatre versus al·legoria filosòfica per a representar i impedir el final tràgic i fosc del lluminós art de pensar.

What is the use of performing the myth of the cave from book VII of the Republic by Plato? Josep Palau i Fabre, considers that, in Plato's dialogues, the speakers are mere instruments at the service of his dialectical goal. The aim of this article is to show how, by turning the myth into a tragedy and also by relying on Heraclitus's conflict or war of opposites, the playwright succeeds in favoring a sort of thought which is not one-sided or univocal. On the contrary, in Palau i Fabre's La Caverna, the tragic hero, that is, the released prisoner transformed by the light of Reality and finally killed by his "cavemates" -after having been imprisoned again and having tried to rescue them from their ignorance or shadows-, still leaves to them his powerful experience of the agonistikos thought, which might bear fruit in their life to come.
