Investigation of cognition in schizophrenia: psychometric properties of instruments for assessing working memory updating

Objective This study describes the development of two updating measures of working memory (WM): Letter Updating Test (LUT) and Word Updating Test (WUT). Methods In stage 1, items were created and the instruments were assessed by experts and laymen. In stage 2, tests were given to 15 patients with schizophrenia and 15 paired controls. All were able to understand and respond to the instruments. In stage 3, 141 patients with schizophrenia and 119 healthy controls aged 18 to 60 took part; they were assessed on WM, processing speed (PS) and functional outcome. Results The results showed adequate rates of internal consistency for both measures developed, for both the total sample and each group separately, as well as evidence of convergent validity, discriminant validity and sensitivity to differentiate performance among the groups. Principal component analysis yielded two components, one for updating tests and other for PS measures, indicating factorial validity. Positive and significant, yet low, correlations were found with functionality measures. Conclusion These results provide adequate psychometric parameters for the measures developed, applicable to cognitive research settings in schizophrenia.

Stress, cognitive appraisal, and psychological health: testing instruments for health professionals

The job of health professionals, including nurses, is considered inherently stressful (Lee & Wang, 2002; Rutledge et al., 2009), and thus it is important to improve and develop specific measures that are sensitive to the demands that health professionals face. This study analysed the psychometric properties of three instruments that focus on the professional experiences of nurses in aspects related to occupational stress, cognitive appraisal, and mental health issues. The evaluation protocol included the Stress Questionnaire for Health Professionals (SQHP; Gomes, 2014), the Cognitive Appraisal Scale (CAS; Gomes, Faria, & Gonçalves, 2013), and the General Health Questionnaire-12 (GHQ-12; Goldberg, 1972). Validity and reliability issues were considered with statistical analysis (i.e. confirmatory factor analysis, convergent validity, and composite reliability) that revealed adequate values for all of the instruments, namely, a six-factor structure for the SQHP, a five-factor structure for the CAS, and a two-factor structure for the GHQ-12. In conclusion, this study proposes three consistent instruments that may be useful for analysing nurses’ adaptation to work contexts.

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.

Environmental regulation: choice of instruments under imperfect compliance

Compliance is an important issue in environmental regulation. In this paper, we discuss some of the key elements of the problem and analyze a situation where emissions are not random and firms are risk-neutral. We study the firm's decision on emissions and compliance when the environmental regulation is based on standards and the enforcement agency audits the firm with a certain probability. We then compare total emissions when environmental regulation is based on different instruments: standards, taxes, and tradable permits. We show that when compliance is an issue, environmental taxes are superior to the other instruments. We also analyze the (static) efficiency of the solution.

Treball de recerca realitzat per alumnes d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. Sobre la base dels coneixements musicals i físics previs de totes les membres del grup, l’objectiu ha estat relacionar-los i ampliar-los fins a aconseguir una comprensió dels mecanismes de producció del so en els diferents tipus d’instruments de l’orquestra.

The Role of Institutions in Cross-Section Income and Panel Data Growth Models: A Deeper Investigation on the Weakness and Proliferation of Instruments

This paper investigates the role of institutions in determining per capita income levels and growth. It contributes to the empirical literature by using different variables as proxies for institutions and by developing a deeper analysis of the issues arising from the use of weak and too many instruments in per capita income and growth regressions. The cross-section estimation suggests that institutions seem to matter, regardless if they are the only explanatory variable or are combined with geographical and integration variables, although most models suffer from the issue of weak instruments. The results from the growth models provides some interesting results: there is mixed evidence on the role of institutions and such evidence is more likely to be associated with law and order and investment profile; government spending is an important policy variable; collapsing the number of instruments results in fewer significant coefficients for institutions.

Coordinació docent concreta i grups pilot EEES com a instruments per la millora de la qualitat docent i com a estratègia per la migració a l'EEES a Facultat de Dret

El projecte s'ha dut a terme a la Facultat de Dret de la Universitat de Barcelona durant el curs 2006-2007 (setembre a juliol). La finalitat principal del projecte ha estat impulsar la coordinació entre docents d'un mateix grup i iniciar la transició cap a l'Espai Europeu d’Ensenyament Superior. En aquest context, les accions desenvolupades han estat la creació de 6 grups pilot (tres a primer, dos a segon i un a tercer) adaptats a l'EEES i la formació d'equips docents dels professors implicats en aquests grups. Des de la Facultat de Dret, es van determinar les característiques i els criteris metodològics que definirien aquests grups i que els docents implicats havien de seguir. Per altra banda, els professors que formaven part d’un mateix grup es constituïen com a equip docent amb la funció de coordinar-se pel bon desenvolupament del grup. Cada equip docent comptava amb la figura del coordinador que era un docent del grup escollit pel conjunt de professors i que tenia com a funcions la de convocar les reunions, redactar les actes amb els acords establerts i fer d’enllaç entre els alumnes i els docents d’un mateix grup. El desenvolupament del projecte s’ha efectuat en tres fases: planificació i definició dels grups pilot i equips docents, l’execució del curs en els criteris metodològics establerts i la de valoració de l’experiència.

Market-Based Instruments for ecosystem services: institutional innovation or renovation?

Recent years have seen widespread experimentation with market-based instruments (MBIs) for the provision of environmental goods and ecosystem services. However, little attention has been paid to their design or to the effects of the underlying pro-market narrative on environmental policy instruments. The purpose of this article is to analyze the emergence and dissemination of the term "market-based instruments" applied to the provision of environmental services and to assess to what extent the instruments associated are genuinely innovative. The recommendation to develop markets can lead in practice to a variety of institutional forms, as we show it based on the example of payments for environmental services (PES) and biodiversity offsets, two very different mechanisms that are both presented in the literature as MBIs. Our purpose is to highlight the gap between discourse and practice in connection with MBIs.
