North-south trade and directed technical change

In a world where poor countries provide weak protection for intellectual propertyrights, market integration shifts technical change in favor of rich nations. Throughthis channel, free trade may amplify international income differences. At the sametime, integration with countries where intellectual property rights are weakly protectedcan slow down the world growth rate. A crucial implication of these results is thatprotection of intellectual property is most beneficial in open countries. This prediction,which is novel in the literature, finds support in the data on a panel of 53 countriesobserved in the years 1965-1990.

Embodied technical change and the fluctuations of wages and unemployment

The paper shows that a matching model where technological change is partially embodied in the job match is successful in explaining the variability of unemployment and vacancies. If we incorporate long-term wage contracts into the model, it also explains a number of stylized facts on the dynamics of real wages, which have been found in the empirical labor literature.

Posterior quadrantic epilepsy surgery: technical variants, surgical anatomy, and case series.

OBJECTIVE: Patients with intractable epilepsy due to extensive lesions involving the posterior quadrant (temporal, parietal, and occipital lobes) form a small subset of epilepsy surgery. This study was done with a view to analyze our experience with this group of patients and to define the changes in the surgical technique over the last 15 years. We also describe the microsurgical technique of the different surgical variants used, along with their functional neuroanatomy. METHODS: In this series there were 13 patients with a median age of 17 years. All patients had extensive presurgical evaluation that provided concordant evidence localizing the lesion and seizure focus to the posterior quadrant. The objective of the surgery was to eliminate the effect of the epileptogenic tissue and preserve motor and sensory functions. RESULTS: During the course of this study period of 15 years, the surgical procedure performed evolved toward incorporating more techniques of disconnection and minimizing resection. Three technical variants were thus utilized in this series, namely, (i) anatomical posterior quadrantectomy (APQ), (ii) functional posterior quadrantectomy (FPQ), and (iii) periinsular posterior quadrantectomy (PIPQ). After a median follow-up period of 6 years, 12/13 patients had Engel's Class I seizure outcome. CONCLUSION: The results of surgery for posterior quadrantic epilepsy have yielded excellent seizure outcomes in 92% of the patients in the series with no mortality or major morbidity. The incorporation of disconnective techniques in multilobar surgery has maintained the excellent results obtained earlier with resective surgery.

Socio-economic inequalities in health in Catalonia

In this paper we measure the degree of income related inequality in mental health as measured by the GHQ instrument and general health as measured by the EQOL-5D instrument for the Catalan population. We find that income is the main contributor to inequality, although the share of inequality in mental health that can be explained by income is much greater than the corresponding share of inequality in general health. We also find that the variation in demographic structure reduces income related inequality in mental health but increases income related inequality in general health. The regional variations in both instruments for health are striking, with the Barcelona districts faring relatively bad with respect to the rest of geographical areas and Lleida being the health region where, all else held equal, the population reports the greatest level of health. A big share of inequality in the two health measures, but specially mental health, is due to the favourable position in both health and income of those who enjoy an indefinite contract with respect to the rest of individuals. We also find that risky working conditions affect both health measures and are able to explain an important share of socio-economic inequality.

Identifying the gap between need and intervention for alcohol use disorders in Europe.

AIMS: A literature review of existing research on the prevalence of alcohol use disorders (AUDs) and availability of alcohol interventions in Europe was conducted. The review also explored what is known about the gap between need and provision of alcohol interventions in Europe. METHODS: The review search strategy included: (i) descriptive studies of alcohol intervention systems in Europe; (ii) studies of alcohol service provision in Europe; and (iii) studies of prevalence of AUD and alcohol needs assessment in Europe. RESULTS: Europe has a relatively high level of alcohol consumption and the resulting disabilities are the highest in the world. Most research on implementation of alcohol interventions in Europe has been restricted to screening and brief interventions. Alcohol needs assessment methodology has been developed but has not been applied in comparative studies across countries in Europe. CONCLUSIONS: This review points to key gaps in knowledge related to alcohol interventions in Europe. There is a lack of comparative data on variations in alcohol treatment systems across European countries and there is also a lack of comparative data on the prevalence of alcohol use disorders across European countries and the relative gap between need and access to treatment. The forthcoming Alcohol Measures for Public Health Research Alliance (AMPHORA) research project work package on 'Early identification and treatment' aims to address these gaps.

Effects of a treatment gap during adjuvant chemotherapy in node-positive breast cancer: results of International Breast Cancer Study Group (IBCSG) Trials 13-93 and 14-93.

BACKGROUND: The International Breast Cancer Study Group (IBCSG) conducted two complementary randomized trials to assess whether a treatment-free gap during adjuvant chemotherapy influenced outcome. PATIENTS AND METHODS: From 1993 to 1999, IBCSG Trials 13-93 and 14-93 enrolled 2215 premenopausal and postmenopausal women with axillary node-positive, operable breast cancer. All patients received cyclophosphamide (Cytoxan, C) plus either doxorubicin (Adriamycin, A) or epirubicin (E) for four courses followed immediately (No Gap) or after a 16-week delay (Gap) by classical cyclophosphamide, methotrexate, and fluorouracil (CMF) for three courses. The median follow-up was 7.7 years. RESULTS: The Gap and No-Gap groups had similar disease-free survival (DFS) and overall survival (OS). No identified subgroup showed a statistically significant difference, but exploratory subgroup analysis noted a trend towards decreased DFS for Gap compared with No Gap for women with estrogen receptor (ER)-negative tumors not receiving tamoxifen, especially evident during the first 2 years. CONCLUSIONS: A 16-week gap between adjuvant AC/EC and CMF provided no benefit and may have increased early recurrence rates in patients with ER-negative tumors.

Bridging the Accountability Gap: Rights for New Entities in the Information Society?

Technological developments in the information society bring new challenges, both to the applicability and to the enforceability of the law. One major challenge is posed by new entities such as pseudonyms, avatars, and software agents that operate at an increasing distance from the physical persons "behind" them (the "principal"). In case of accidents or misbehavior, current laws require that the physical or legal principal behind the entity be found so that she can be held to account. This may be problematic if the linkability of the principal and the operating entity is questionable. In light of the ongoing developments in electronic agents, there is sufficient reason to conduct a review of the literature in order to more closely examine arguments for and against legal personhood for some nonhuman acting entities. This article also includes a discussion of alternative approaches to solving the "accountability gap."

La société sénégalaise et les enfants de la rue : approche socio-anthropologique des dynamiques d'exclusion et de survie : étude de cas à Dakar

Résumé : La société sénégalaise traverse une crise profonde qui touche tous les secteurs de la vie. Cette crise à la fois structurelle et conjoncturelle crée à son tour une sorte de société de la crise qui touche les populations les plus vulnérables. Le phénomène des enfants de la rue est l'expression parfaite de cette société de la crise. Le rythme dans lequel il se développe est la traduction de la dynamique d'exclusion qui sévit en milieu urbain sénégalais en général et dans la région de Dakar en particulier. Dans cette région, l'urbanisation s'est accompagnée de la montée des inégalités qui placent la société dans une sorte de dualisation entre centre et périphérie. A la ville de Dakar qui s'est constituée selon les normes de la planification urbaine, s'oppose les principales banlieues de Pikine, Guédiawaye et Rufisque qui offrent le visage de marges sociales urbaines. D'une certaine manière, la montée des inégalités remet en cause les politiques sociales, de la bonne gouvernance et de la redistribution des richesses. Ces banlieues constituent les principaux milieux d'accueil de la masse de migrants ruraux qui fuient la misère des villages. D'une part, l'hétérogénéité sociale de ces banlieues ne favorise pas l'émergence d'une conscience collective fondée sur l'appartenance à un fonds historique commun. Par contre, elle renforce l'anonymat et l'indifférence propres à la ville. D'autre part, les difficultés économiques et la précarité des conditions de vie conjuguées à l'explosion démographique et ses conséquences affaiblissent les systèmes de solidarité entraînant ainsi la montée de l'individualisme et la philosophie du chacun pour soi. Ce qui met en cause l'éducation des enfants qui devient difficile pour les parents d'assumer. En outre, la place importante accordée à l'imaginaire social dans la société sénégalaise explique le recours aux forces surnaturelles par l'intercession des marabouts, sorciers, devins, etc. D'autre part, la place accordée aux offrandes et aux sacrifices de même que le "besoin de donner" alimente et pérennise la pratique de la mendicité en général et celle des enfants en particulier. En outre, l'instrumentalisation de la mendicité par certains marabouts qui se traduit par une sorte de "business talibé" ou de "marché de l'aumône", rapproche les enfants de l'univers de là rue qui devient pour eux une sorte d'échappatoire face aux conditions de vie que leur imposent ces marabouts. Ainsi, pour eux, la rue remplit une fonction de socialisation. En effet, dans cet univers social, les enfants se forgent une personnalité, développent des compétences et des activités qui leur permettent de survivre, créent des repères et des codes collectifs qui leur permettent de mener une existence que la société assimile strictement à la déviance. Mots clé : crise, école, éducation, enfants de la rue, exclusion, inégalités, migration, pauvreté, socialisation, stratégies de survie, uibanisation.

Globalization and culture shaping the gender gap: A comparative analysis of urban Latin America and East Asia (1970 - 2000)

In this paper we present: 1. The available data on comparative gender inequality at themacroeconomic level and 2. Gender inequality measures at the microeconomic and case studylevel. We see that market openness has a significant effect on the narrowing of the human capitalgender gap. Globalization and market openness stand as factors that improve both the humancapital endowments of women and their economic position. But we also see that the effects ofculture and religious beliefs are very different. While Catholicism has a statistically significantinfluence on the improvement of the human capital gender gap, Muslim and Buddhist religiousbeliefs have the opposite effect and increase human capital gender differences.In the second global era, some Catholic Latin American countries benefited from market opennessin terms of the human capital and income gender gap, whereas we find the opposite impact inBuddhist and Muslim countries like China and South Korea where women s economic positionhas worsened in terms of human capital and wage inequality.

Regional differences in socio-economic health inequalities in Spain

This paper reports an analysis of income related health inequalities at the AutonomousCommunity level in Spain using the self assessed health measure in the 2001 edition of theEncuesta Nacional de Salud. We use recently developed methods in order to cardinalise andmodel self assessed health within a regression framework, decompose the sources ofinequality and explain the observed differences across regions. We find that the regions with the highest levels of mean health tend to enjoy the lowest degrees of income related health inequality and vice-versa. The main feature characterizing regions where income related health inequality is low is the absence of a positive gradient between income and health. In turn, the regions where income related health inequality is greater are characterized by a strong and significant positive gradient between health and income. These results suggest that policies aimed at eliminating the gradient between health and income can potentially lead to greate r reductions in socio-economic health inequalities than policies aimed at redistributing income.

Environmental Services - Recycling Technical Assistance,

Iowa is one of the more progressive recycling states in the U.S. due in large part to its environmental technical assistance programs for business. The Iowa Department of Economic Development (IDED), Iowa Department of Natural Resources (IDNR), the Recycle Reuse Technology Transfer Center (RRTTC) and the Iowa Waste Reduction Center (IWRC) work together to offer services that help businesses save money, increase operational efficiencies, enhance regulatory compliance and manage difficult waste management issues.
