Aquest article s'aplica un enfocament comparatiu de la gestió del sector petrolier en dos països rics en petroli a l'Orient Mitjà : Arà bia Saudita i els Emirats Àrabs Units (EAU). Més explÃcitament, s'examinen els factors que millor expliquen la variació en les estratègies que han vingut aplicant en el sector des de l'establiment de les seves empreses petrolieres nacionals (NOC). Recorrent a la literatura sobre expropiació / privatització en el camp d'Estudis de l'Energia, en aquest treball es proposa un marc teòric per analitzar la lògica que hi ha al darrera de les diferents formes d'exploració i les estratègies de producció en el sector petrolier. Teòricament, aquesta investigació té com a objectiu avançar en un conjunt d'eines d'anà lisi per abordar millor i entendre els determinants reals del procés de presa de decisions en el upstream. EmpÃricament, el model es prova en els casos divergents d'Arà bia Saudita i els Emirats Àrabs Units, i una sèrie de lliçons s'han extret. En última instà ncia, aquest treball ha d'augmentar la conscienciació entre els erudits i els polÃtic, tant sobre el poc coneixement que tenim sobre els mecanismes interns que impulsen les estratègies ascendents en el majors estats productor de petroli.

This paper analyses the economic growth performance in the Arab world overthe last forty years. The Arab world has managed to reduce povertyperformance despite its relatively disappointing growth performance. Werelate this poor performance of both oil and non-oil producers toinvestment. Contrary to widespread belief, we do not find evidence that lowquantity of investment is the main of low growth. The decline in theinvestment rate followed rather than preceded the reduction in the aggregategrowth rate. We conclude that the low quality of investment projects is thekey determinant of growth. The excessive reliance on public investment, thelow quality of financial institutions, the bad business environment (due topolitical and social instability and to excessive public intervention andoverregulation) and the low quality of human capital are importantdeterminants of systematically unproductive investment decisions and, thus,low economic growth.

The aim of this article is to present the main conclusions of the Report on research in Catalonia for the area of mathematics**. The report was prepared by Joaquim Bruna, Marta Sanz, Joan de Solà -Morales and the author of this text, and published by the Institute for Catalan Studies in 1998. In the report, scientific activity in the area of mathematics was measured essentially by examining two parameters: papers published in specialised journals and doctoral theses read. It should be recognised that a considerable amount of activity in the field of mathematics consists of applying existing knowledge to the resolution of practical technological problems that arise in particular companies. This kind of scientific activity was not measured in any way in the report due to the difficulty of obtaining objective data. This article is divided into the following sections: human resources, scientific production, funding, research publications, research centres, and conclusions.

Un conocido dicho sufà dice que: "El color del agua es el color de su recipiente". Para hablar de la visión teofánica, al-Junayd, Ibn 'Arabi y otros muchos mÃsticos invocaban frecuentemente este sÃmbolo. Según al-Bistami, el color del recipiente -el corazón del contemplador- da "color" al agua que en sà es invisible; según Ibn 'Arabi, no es el corazón quien da su "color" a la Forma que recibe, sino que, a la inversa, el corazón del gnóstico "se colorea" en cada instante con el color, es decir, con la modalidad de la Forma bajo la cual el Ser divino se epifaniza en él. Asà es como "l gnóstico,asume las peculiaridades del carácter de Dios, hasta tal punto que parece como si él fuera El". El propósito del presente artÃculo es analizar la teorÃa neoplatónica de la manifestación de lo divino expresada por medio de dos parábolas -el color del agua y el color del vidrio- presentes tanto en la tradición islámica como en la judÃa.

The aim of this studywas to adapt and assess the psychometric properties of the Spanish version of the sMARS in terms of evidence of validity and reliability of scores. The sMARS was administered to 342 students and, in order to assess convergent and discriminant validity, several subsamples completed a series of related tests. The factorial structure of the sMARSwas analyzed by means of a confirmatory factor analysis and results showed that the three-factor structure reported in the original test fits well with the data. Thus, three dimensions were established in the test: math test, numerical task and math course anxiety. The results of this study provide sound evidence that demonstrates the good psychometric properties of the scores of the Spanish version of the sMARS: strong internal consistency, high 7-week testretest reliability and good convergent/discriminant validity were evident. Overall, this study provides an instrument that allows us to obtain valid and reliable math anxiety measurements. This instrument may be a useful tool for educators and psychologists interested in identifying individuals that may have a low level of math mastery because of their anxiety.
