We report here a new empirical density functional that is constructed based on the performance of OPBE and PBE for spin states and SN 2 reaction barriers and how these are affected by different regions of the reduced gradient expansion. In a previous study [Swart, Sol̀, and Bickelhaupt, J. Comput. Methods Sci. Eng. 9, 69 (2009)] we already reported how, by switching between OPBE and PBE, one could obtain both the good performance of OPBE for spin states and reaction barriers and that of PBE for weak interactions within one and the same (SSB-sw) functional. Here we fine tuned this functional and include a portion of the KT functional and Grimme's dispersion correction to account for π- π stacking. Our new SSB-D functional is found to be a clear improvement and functions very well for biological applications (hydrogen bonding, π -π stacking, spin-state splittings, accuracy of geometries, reaction barriers)

Our paper presents a pilot project (INTERNORM) funded by the University of Lausanne to support the involvement of not-for-profit organisations in international standard setting bodies such as the ISO. It analyses preliminary results on how a distinct participatory mechanism can influence the institutional environment of technical diplomacy in which ISO standards are developed. It reflects on the contribution of innovative deliberative mechanisms to democratise the field of international standardisation, largely dominated by expert knowledge and market players. It draws upon international relations literature on new institutional forms in global governance and social studies of science on participatory issues in science-society relations. The paper argues that there are significant limitations to the rise of civil society participation in such global governance mechanisms and examines several types of barriers to the involvement of not-for-profit organisations in ISO standard-setting processes. Notre communication porte sur un projet pilote (INTERNORM) financé par l'Université de Lausanne pour favoriser l'implication des acteurs associatifs dans l'élaboration des normes internationales de type ISO. Elle analyse les effets d'un dispositif participatif sur l'environnement institutionnel très particulier de la diplomatie technique ayant cours à l'ISO. Elle présente les résultats intermédiaires d'une réflexion sur l'apport de dispositifs délibératifs pour démocratiser le champ de la normalisation internationale, largement dominé par le savoir expert et les acteurs économiques. Elle situe cette réflexion au croisement des travaux de relations internationales sur les nouvelles formes institutionnelles de la gouvernance de la mondialisation et des études sociales des sciences et des techniques sur la participation dans les rapports science - société. En identifiant plusieurs registres dans lesquels situer les difficultés d'une plus grande implication des acteurs associatifs dans les procédures d'élaboration de spécifications techniques de type ISO, nous posons l'hypothèse qu'il existe d'importantes limites à l'accroissement de la dimension participative de la gouvernance globale.

The goal of this interdisciplinary study is to better understand the land use factors that increase vulnerability of mountain areas in northern Pakistan. The study will identify and analyse the damages and losses caused by the October 2005 earthquake in two areas of the same valley: one "low-risk" watershed with sound natural resources management, the other, "high-risk" in an ecologically degraded watershed. Secondly, the study will examine natural and man-made causes of secondary hazards in the study area, especially landslides; and third it will evaluate the cost of the earthquake damage in the study areas on the livelihoods of local communities and the sub-regional economy. There are few interdisciplinary studies to have correlated community land use practices, resources management, and disaster risk reduction in high-risk mountain areas. By better understanding these linkages, development- humanitarian- and donor agencies focused on disaster reduction can improve their risk reduction programs for mountainous regions.

OBJECTIVES: To determine the distribution of exercise stages of change in a rheumatoid arthritis (RA) cohort, and to examine patients' perceptions of exercise benefits, barriers, and their preferences for exercise. METHODS: One hundred and twenty RA patients who attended the Rheumatology Unit of a University Hospital were asked to participate in the study. Those who agreed were administered a questionnaire to determine their exercise stage of change, their perceived benefits and barriers to exercise, and their preferences for various features of exercise. RESULTS: Eighty-nine (74%) patients were finally included in the analyses. Their mean age was 58.4 years, mean RA duration 10.1 years, and mean disease activity score 2.8. The distribution of exercise stages of change was as follows: precontemplation (n = 30, 34%), contemplation (n = 11, 13%), preparation (n = 5, 6%), action (n = 2, 2%), and maintenance (n = 39, 45%). Compared to patients in the maintenance stage of change, precontemplators exhibited different demographic and functional characteristics and reported less exercise benefits and more barriers to exercise. Most participants preferred exercising alone (40%), at home (29%), at a moderate intensity (64%), with advice provided by a rheumatologist (34%) or a specialist in exercise and RA (34%). Walking was by far the preferred type of exercise, in both the summer (86%) and the winter (51%). CONCLUSIONS: Our cohort of patients with RA was essentially distributed across the precontemplation and maintenance exercise stages of change. These subgroups of patients exhibit psychological and functional differences that make their needs different in terms of exercise counselling.

Premature deterioration of slip formed portland cement concrete (PCC) barriers is an ongoing problem in the Iowa Primary and Interstate highway system. The requirement to have a concrete mix which can be sufficiently pliable to be readily molded into the barrier shape and yet be sufficiently stiff to maintain a true shape and height immediately after molding is difficult to meet. A concrete mix which is stiff enough to maintain its shape immediately after molding is usually difficult to work with. It often contains open or hidden tears and large voids. One way to minimize the molding resistance is by additional vibration. If intensive vibration is applied, the entrapped air voids and tears in the concrete can usually be eliminated, however, in that process, the essential entrained air content can also be lost. In the evaluation of slip formed PCC barriers, it is common to find large voids, tears and a low entrained air content, all contributing to premature deterioration. A study was initiated to evaluate core samples taken from good and from bad appearing areas of various median barriers. Evaluations were done covering visual appearance, construction information, air content and chloride content.

The price-wedge method yields a tariff-equivalent estimate of technical barriers to trade (TBT). An extension of this method accounts for imperfect substitution between domestic and imported goods and incorporates recent findings on trade costs. We explore the sensitivity of this revamped TBT estimate to its key determinants (substitution elasticity, preference for home good, and trade cost). We use the augmented approach to investigate the ongoing US-Japan apple trade dispute and find that removing the Japanese TBT would yield limited export gains to the United States. We then draw policy implications of our findings.

The current research compares the perception of over-education in four different European countries, resorting to European Household Panel Data. The results confirm that the type of educational system accounts for some of the cross-national differences in self-perceived over-education. In qualificational spaces, like Denmark, where vocational training receives more importance, self-perceived over-education is not associated as much with educational attainment as in the so-called’ organisational spaces’, like Spain, France and Italy. Yet, the results confirm that, controlling for the system of education, the traits and regulation of the labour market also have an effect on over-education. Thus, in Spain, where temporary employment has soared in recent decades, this type of contract is clearly associated with the perception of over-education, to a much higher extent than in Italy or France. Temporary contracts in Spain may not work as a steppig stone for attaining a job suitable to the training received by the individual, as they may in the case of France or Italy. In sum, not only institutions offering skills and human capital, but labour market regulation as well, have a clear impact on the incidence of over-education.

During the last five years, Iowa has experienced a shortage of workers and will continue to feel the impact of a short labor supply. As the state prepares to reverse this trend of a declining population, attracting immigrants and refugees has great potential. In addition, released preliminary reports from the 2000 Census are reporting growth of the Latino population in several Iowa counties. This survey was conducted as a way to supplement the information collected about the Latino population by the State Public Policy Group in 1999, Snapshot in Time: A clear view of the importance, value and impacts of the Latino population in central Iowa. (Una Foto Actual de la Comunicad Latina: Un panoramaclaro de la importancia, del valor, y de los impactos de la población Latina en el área central de Iowa.) Although this survey was enlightening, it was broad in scope. It was the goal of the agency to collect more specific data regarding workforce needs and barriers that the Latino population encounter in the State of Iowa. Although it was the desire to broaden the scope of the previous survey, it should be noted that the survey samples were not identical. But it is recognized that because the Latino population within the state is small, some of the respondents could have participated in both surveys. We were also hoping to benefit from the extensive work conducted by SPPG within the community as a way to increase the response rate for this survey. This executive summary highlights some of the most significant findings from the survey of Latinos residing in Central Iowa. This analysis centers on the impact the Latino population can have in filling the labor shortages and how Iowa can best embrace the new Iowan. In addition, some of the key findings could offer insight into removing unnecessary barriers that prevent immigrants from utilizing valuable work skills as they integrate into the workforce. This information may be insightful to community leaders and employers who want to welcome new immigrants into their community. The following diagram collected from the 2000 Census illustrates the percentage of Latinos residing in the state.

In light of the existing theories about institutional change, this paper seeks to advance a common framework to understand the unfolding of decentralization and federalization in three countries: Brazil, Spain, and South Africa. Although in different continents, these three countries witnessed processes after their respective transitions to democracy that transferred administrative and fiscal authority to their regions (decentralization) and vertically distributed political and institutional capacity (federalization). This paper attempts to explain how institutional changes prompted a shift of power and authority towards regional governments by looking at internal sources of change within the intergovernmental arena in the three countries. This analysis is organized around two propositions: that once countries transit to democracy under all-encompassing constitutions there are high incentives for institutional change, and that under a bargained intergovernmental interaction among political actors subnational political elites are able to advance their interests incrementally. In short, through a common framework this paper will explain the evolving dynamics of intergovernmental dynamics in three countries.

Context.-Unlike the small bowel, the colorectal mucosa is seldom the site of metastatic disease. Objective.-To determine the incidence of truly colorectal metastases, and subsequent clinicopathologic findings, in a substantial colorectal cancer population collected from 7 European centers. Design.-During the last decade, 10 365 patients were identified as having colorectal malignant tumors, other than systemic diseases. Data collected included patient demographics, clinical symptoms, treatment, the presence of metastases in other sites, disease-free interval, follow-up, and overall survival. All secondary tumors resulting from direct invasion from malignant tumors of the contiguous organs were excluded, as well as those resulting from lymph node metastases or peritoneal seeding. Results.-Only 35 patients were included (10 men) with a median age of 59 years. They presented with obstruction, bleeding, abdominal pain, or perforation. The leading source of metastases was the breast, followed by melanoma. Metastases were synchronous in 3 cases. The mean disease-free interval for the remaining cases was 6.61 years. Surgical resection was performed in 28 cases. Follow-up was available for 26 patients; all had died, with a mean survival time of 10.67 months (range, 1-41 months). Conclusions.-Colorectal metastases are exceptional (0.338%) with the breast as a leading source of metastases; they still represent a late stage of disease and reflect a poor prognosis. Therefore, the pathologist should be alert for the possibility of secondary tumors when studying large bowel biopsies. Any therapy is usually palliative, but our results suggest that prolonged survival after surgery and complementary therapy can be obtained in some patients.

The paper deals with the comparative study of European citizens' satisfaction with the state of education in their respective countries. Individual and contextual effects are tested applying multilevel analysis. The results show that educational public policies (level of decentralization, degree of comprehensiveness and public spending) as well as the students' social environment (socioeconomic and cultural status) have a sound impact on the opinions about the state of education.

Simplifying business formalization and eliminating outdated formalities is often a good way of improving the institutional environment for firms. Unfortunately, the World Bank's Doing Business project is harming such policies by promoting a reform agenda that gives them priority even in countries lacking functional business registers, so that the reformed registers keep producing valueless information, but faster. Its methodology also promotes biased measurements that impede proper consideration of the essential tradeoffs in the design of formalization institutions. If Doing Business is to stop jeopardizing its true objectives and contribute positively to scientific progress, institutional reform and economic development, then its aims, governance and methodology need to change.
