Why do overeducated workers participate in non-formal education activities? Do not they suffer from an excess of education? Using microdata from the Spanish sample of the 2007 Adult Education Survey, we have found that overeducated workers participate more than the rest in non-formal education and that they earn higher wages than overeducated workers who did not participate. This result can be interpreted as evidence that non-formal education allows overeducated workers to acquire new abilities that improve their competence at the job they perform. From this point of view, our results support the European Commission"s view on the need to reinforce lifelong learning among adult population.

The objective of phase one of this research was to assess the degree to which currently employed Iowa Department of Transportation (DOT) employees would be affected by a more aggressive policy to recruit and retain women and minority engineers. The DOT's "Future Agenda" was used as a baseline to focus on efforts to update and implement a recruitment plan that would target underrepresented classes. The primary question that emerged out of phase one was how could the Iowa DOT strengthen its ties with Iowa State University (ISU) to produce increased numbers of in-state applicants for engineering positions. This introduced the objective of phase two, which was to identify problem areas resulting in unacceptably high attrition rates for women, minorities, and to a lesser degree, Caucasian men in the College of Engineering at ISU, particularly Civil and Construction Engineering (CCE). Past research has focused on (1) projected shortages of qualified civil engineers, (2) the obstacles confronting women in a traditionally male-oriented profession, and (3) minorities who are often unprepared to succeed in the rigors of an engineering curriculum because of a lack of academic preparedness. The researchers in this study, in contrast, chose to emphasize institutional reasons why women, minorities, and some Caucasian men often feel a sense of isolation in the engineering program. It was found that one of the key obstacles to student retention is the lack of visibility of the civil engineering profession. The visibility problem led to the hypothesis that many engineering students do not have a clear conception of what the practice of civil engineering entails. It was found that this may be a better predictor of attrition than the stereotypical assumption that a majority of students leave their engineering programs because they are not academically able to compete. Recommendations are offered to strengthen the ties between ISU's Department of CCE and the Iowa DOT in order to counter the visibility issue. It was concluded that this is a vital step because over the next 5-15 years 40% of DOT engineers currently employed will be phasing into retirement. If the DOT expects to draw sufficient numbers of engineers from within the state of Iowa and if increasing numbers of them are to be women and minorities, a university connection will help to produce the qualified applicants to fulfill this need.

This chapter explores the institutional environments in which standards for the service sector are expected to support the rise of a global knowledgebased economy. The analysis relies on global political economy approaches to extend to the area of services standards the assumption that the process of globalisation is not opposing states and markets, but a joint expression of both of them including new patterns and agents of structural change through formal and informal power and regulatory practices. It analyses how services standards gain authority in the institutional environment in Europe and in the United States and the extent to which this authority is recognised at the transnational level. In contrast to conventional views opposing the European and American standardisation systems, the chapter shows that institutional developments of services standards are likely to face trade-offs and compromises across those systems.

Constituye hoy una preocupación social e intelectual que atañe particularmente al profesorado, la identificación de los mecanismos a través de los cuales se transmiten y se afianzan los sistemas de valores en la infancia y en la juventud. También interesa de manera especial, a tenor de la frecuencia de su uso político y público, la definición y construcción de las identidades y, muy en concreto, de las nacionales. En este sentido, buena parte de las investigaciones actuales indica que, a partir de los últimos decenios del siglo XX, la transmisión y construcción de valores e identidades se comunican y se construyen prioritariamente a través de las redes mediática

A partir de la existencia de unos determinados niveles de participación en la tecnología, alcanzados por los trabajadores y representantes sindicales de quince empresas del sector «auxiliar» del automóvil de Cataluña, un análisis de la «cultura global» de cada una de esas empresas ¿esta última, deducida de la «agregación» de la cultura directiva y sindical existentes en esas empresas¿ permitió comprobar que tales niveles de participación estaban altamente relacionados con el tipo de concepciones ideológico-culturales ¿ideas, valores y representaciones simbólicas¿ presentes en la cultura de cada uno de esos dos actores sociales. En particular, en la de los directivos, que fue la que demostró poseer la mayor hegemonía para determinar la «cultura global» de cada empresa y, con ello, el grado de ajuste existente entre dicha «cultura global» y los niveles de participación alcanzados por los trabajadores en la innovación tecnológica. El resultado final fue que la «cultura global» fue capaz de explicar los niveles de participación detectados en trece de las quince empresas estudiadas.

El sector informal como recurso, se refiere a la red de provisión, que en un rol amplio, ayuda a resolver problemas identificados en el sector formal de salud y sociosanitario. Se refiere a diferentes tipos de arreglos cotidianos que las personas desarrollan o ponen en práctica, para cuidarse y atenderse entre sí. La autora centra su reflexión en los dilemas y límites, individuales y sociales que plantea el cuidado informal, y tiene especialmente en cuenta el impacto e importancia desde la perspectiva de género, ya que el cuidado informal es un recurso central en la atención a la dependencia y fragilidad. Los retos a resolver tienen que ver con los modos de relación y el impacto de los mismos sobre la organización social del cuidar y de los cuidados en la protección a las situaciones de fragilidad y dependencia.

El objeto central de este artículo es presentar y debatir algunos aspectos conceptuales de la relación entre la animación sociocultural y la educación. Para ello, en primer lugar se polemiza con algunos posicionamientos reticentes o tibios en cuanto a la vinculación pedagógica de la animación sociocultural. Después, el discurso se torna positivo para presentar algunos aspectos relevantes de la relación entre ambos conceptos. Finalmente, se analiza el lugar que le correspondería a la ASC en un universo educativo sectorializado en ámbitos formales, no formales e informales. Antes que nada, sin embargo, a modo de paréntesis introductorio, se esboza una relación de los distintos niveles de elaboración teórica de la ASC, para situar el que correspondería al tema de este trabajo y explicitar asi algunas de sus limitaciones.

U-Pb dating of zircons by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) is a widely used analytical technique in Earth Sciences. For U-Pb ages below 1 billion years (1 Ga), Pb-206/U-238 dates are usually used, showing the least bias by external parameters such as the presence of initial lead and its isotopic composition in the analysed mineral. Precision and accuracy of the Pb/U ratio are thus of highest importance in LA-ICPMS geochronology. We consider the evaluation of the statistical distribution of the sweep intensities based on goodness-of-fit tests in order to find a model probability distribution fitting the data to apply an appropriate formulation for the standard deviation. We then discuss three main methods to calculate the Pb/U intensity ratio and its uncertainty in the LA-ICPMS: (1) ratio-of-the-mean intensities method, (2) mean-of-the-intensity-ratios method and (3) intercept method. These methods apply different functions to the same raw intensity vs. time data to calculate the mean Pb/U intensity ratio. Thus, the calculated intensity ratio and its uncertainty depend on the method applied. We demonstrate that the accuracy and, conditionally, the precision of the ratio-of-the-mean intensities method are invariant to the intensity fluctuations and averaging related to the dwell time selection and off-line data transformation (averaging of several sweeps); we present a statistical approach how to calculate the uncertainty of this method for transient signals. We also show that the accuracy of methods (2) and (3) is influenced by the intensity fluctuations and averaging, and the extent of this influence can amount to tens of percentage points; we show that the uncertainty of these methods also depends on how the signal is averaged. Each of the above methods imposes requirements to the instrumentation. The ratio-of-the-mean intensities method is sufficiently accurate provided the laser induced fractionation between the beginning and the end of the signal is kept low and linear. We show, based on a comprehensive series of analyses with different ablation pit sizes, energy densities and repetition rates for a 193 nm ns-ablation system that such a fractionation behaviour requires using a low ablation speed (low energy density and low repetition rate). Overall, we conclude that the ratio-of-the-mean intensities method combined with low sampling rates is the most mathematically accurate among the existing data treatment methods for U-Pb zircon dating by sensitive sector field ICPMS.

This paper investigates the prevalence of incapacity in performing daily activities and the associations between household composition and availability of family members and receipt of care among older adults with functioning problems in Spain, England and the United States of America (USA). We examine how living arrangements, marital status, child availability, limitations in functioning ability, age and gender affect the probability of receiving formal care and informal care from household members and from others in three countries with different family structures, living arrangements and policies supporting care of the incapacitated. Data sources include the 2006 Survey of Health, Ageing and Retirement in Europe for Spain, the third wave of the English Longitudinal Study of Ageing (2006), and the eighth wave of the USA Health and Retirement Study (2006). Logistic and multinomial logistic regressions are used to estimate the probability of receiving care and the sources of care among persons age 50 and older. The percentage of people with functional limitations receiving care is higher in Spain. More care comes from outside the household in the USA and England than in Spain. The use of formal care among the incapacitated is lowest in the USA and highest in Spain.
