    Subfield Effects on the Core of Coauthors

    Full text link
    It is examined whether the number (JJ) of (joint) publications of a "main scientist" with her/his coauthors ranked according to rank (rr) importance, i.e. J1/r J \propto 1/r , as found by Ausloos [1] still holds for subfields, i.e. when the "main scientist" has worked on different, sometimes overlapping, subfields. Two cases are studied. It is shown that the law holds for large subfields. As shown, in an Appendix, is also useful to combine small topics into large ones for better statistics. It is observed that the sub-cores are much smaller than the overall coauthor core measure. Nevertheless, the smallness of the core and sub-cores may imply further considerations for the evaluation of team research purposes and activities.Comment: 12 figures (can be combined); 37 references; 4 Tables; prepared for and submitted to Scientometric

    Optimal Economic Growth Using Fiscal and Monetary Policies

    The literature on growth theory is rich with models attempting to explain growth differences among countries. Several variables have been proposed many of which were found to be positively related to growth. However, a major problem with these models is that the factors explaining growth are endogenously determined by their environment so that a slow-growing or a poor country will find itself helpless because all the crucial variables it has `inherited' are either deficient or inexistent. We propose policyoriented model that empowers (poor or slow-growing) countries in the sense that they can use economic policies to achieve high growth and eliminate the gap of unused productive capacity of society. We demonstrate that such objectives are possible by manipulating some key control variables, namely the rate of interest and the net government spending.growth, maximization, fiscal policy, interest rates, deficit, money

    Background: This study assessed the international variation in surgical neuro-oncology practice and 30-day outcomes of patients who had surgery for an intracranial tumor during the COVID-19 pandemic. Methods: We prospectively included adults aged ≥18 years who underwent surgery for a malignant or benign intracranial tumor across 55 international hospitals from 26 countries. Each participating hospital recorded cases for 3 consecutive months from the start of the pandemic. We categorized patients’ location by World Bank income groups (high [HIC], upper-middle [UMIC], and low- and lower-middle [LLMIC]). Main outcomes were a change from routine management, SARS-CoV-2 infection, and 30-day mortality. We used a Bayesian multilevel logistic regression stratified by hospitals and adjusted for key confounders to estimate the association between income groups and mortality. Results: Among 1016 patients, the number of patients in each income group was 765 (75.3%) in HIC, 142 (14.0%) in UMIC, and 109 (10.7%) in LLMIC. The management of 200 (19.8%) patients changed from usual care, most commonly delayed surgery. Within 30 days after surgery, 14 (1.4%) patients had a COVID-19 diagnosis and 39 (3.8%) patients died. In the multivariable model, LLMIC was associated with increased mortality (odds ratio 2.83, 95% credible interval 1.37–5.74) compared to HIC. Conclusions: The first wave of the pandemic had a significant impact on surgical decision-making. While the incidence of SARS-CoV-2 infection within 30 days after surgery was low, there was a disparity in mortality between countries and this warrants further examination to identify any modifiable factors

    Service de numérisation à la demande dans les Bibliothèques de l'Université de Liège : Rapport sur la phase pilote de mars à décembre 2016

    Full text link
    Le système de gestion de bibliothèque Alma intègre un processus de gestion des documents numériques (stockage et/ou fourniture). Une analyse préalable sur les possibilités, avantages et limites d'un service de numérisation à la demande géré par Alma, dans le contexte des Bibliothèques de l'Université, a été réalisée en 2015. L'analyse a suggéré la mise en place, pour une phase pilote, d'un service de numérisation partielle à destination des membres du personnel. Le présent rapport fait le point sur cette phase pilote (mars-décembre 2016) et adresse des recommandations pour l'avenir

    IMPORTANCIA DE LA INTERVENCIÓN DEL GOBIERNO Y EL COMERCIO INTERNACIONAL EN LA CREACIÓN DE DESARROLLO REGIONAL DESIGUAL

    No full text
    En un artículo reciente, Robert Baldwin (1992: 828), un teórico reconocido, se preguntó si los puntos de vista tradicionales para explicar el comercio inter­nacional son todavía válidos. Después de revisar los recientes desarrollos en la teoría del comercio, el autor concluye que lo que él llama "la nueva teoría del comercio” "será integrada en este mareo (tradicional) en lugar de reemplazarlo". De cualquier forma, Paul Krugman (I99ib:82), quien, en general, es conside­rado líder de la "nueva teoría del comercio", con base en un análisis de la Historia económica de Estados Unidos, concluye que "no es verdad que nuestra eco­nomía esté a hora bien descrita por el modelo convencional de beneficios constantes

    NEOLIBERALISMO Y CRECIMIENTO ECONÓMICO EN MÉXICO

    No full text
    Después de la crisis de la deuda de 1982, México empezó a instrumentar el programa que, al parecer, era el más liberal y abierto al exterior de su historia. La tendencia a la liberalización continuó a lo largo de la dé­cada de los ochenta y terminó recien­temente en el Tratado de Libre Co­mercio (TLC) con Canadá y Estados Unidos. En este artículo se analizan los vínculos entre las reformas de política impuestas por este programa y el desempeño económico del país durante 1985-1995. Las diversas me­didas y políticas adoptadas durante ese periodo han sido a menudo con­tradictorias e inconsistentes, y pare­cen haber desempeñado un papel principal como causantes de los actua­les problemas económicos que en­frenta México. El documento sos­tiene que así como la liberalización es importante para el crecimiento económico, lo es también para co­locar en su sitio un conjunto de políticas coherentes que puedan promover el crecimiento y evitar que el país pague una gran parte de las consecuencias negativas del proceso de ajuste
