Equilibrium unemployment insurance

In this paper, we incorporate a positive theory of unemployment insuranceinto a dynamic overlapping generations model with search-matching frictionsand on-the-job learning-by-doing. The model shows that societies populatedby identical rational agents, but differing in the initial distributionof human capital across agents, may choose very different unemploymentinsurance levels in a politico-economic equilibrium. The interactionbetween the political decision about the level of the unemployment insuranceand the optimal search behavior of the unemployed gives rise to aself-reinforcing mechanism whichmay generate multiple steady-stateequilibria. In particular, a European-type steady-state with highunemployment, low employment turnover and high insurance can co-exist withan American-type steady-state with low unemployment, high employment turnoverand low unemployment insurance. A calibrated version of the model featurestwo distinct steady-state equilibria with unemployment levels and durationrates resembling those of the U.S. and Europe, respectively.

Drug utilization studies and data registries in primary care

This article reviews the methodology of the studies on drug utilization with particular emphasis on primary care. Population based studies of drug inappropriateness can be done with microdata from Health Electronic Records and e-prescriptions. Multilevel models estimate the influence of factors affecting the appropriateness of drug prescription at different hierarchical levels: patient, doctor, health care organization and regulatory environment.Work by the GIUMAP suggest that patient characteristics are the most important factor in the appropriateness of prescriptions with significant effects at the general practicioner level.

Implantació d'un sistema de gestió integrada: ISO 9001:00, ISO 14001:04 i OHSAS 18001:07, en un centre d'estètica i perruqueria

En aquests últims anys, són moltes les empreses que han optat per la utilització de sistemes de gestió normalitzats, per a garantir la rendibilitat i fiabilitat dels resultats de la implantació del sistema de gestió en qüestió. A la dècada dels 90 va ser quan la implantació de sistemes de gestió va començar a ser important en la majoria de sectors econòmics. L’evolució en els sistemes de gestió a trets generals va iniciar-se primerament en l’àmbit de la qualitat, seguidament en la gestió ambiental i en última instància en la prevenció de riscos laborals. Aquests tres tipus de sistemes de gestió, en els últims anys s’han anat integrant, de manera que s’han reduït els recursos i els esforços emprats en la gestió, millorant significativament l’eficàcia i l’eficiència d’aquests sistemes. L’objectiu principal que persegueix aquest projecte, és definir un sistema de gestió que permeti a l’empresa conduir les seves activitats de forma simplificada i ordenada, i que alhora faciliti la informació necessària per a corregir i millorar les activitats. Un altre objectiu que pretén aconseguir aquest projecte, és el de dissenyar un SGI que aprofiti les sinèrgies generades en els diferents àmbits de la pròpia empresa i fomenti les interaccions entre els diferents nivells de l’organització. En conseqüència, millorarà de forma important els fluxos d’informació dins de l’empresa minimitzant els esforços i la pèrdua d’informació. El mètode escollit per a la implantació del SGI, ha estat la Gestió per Processos, la qual es basa en la definició i seguiment dels processos de l’empresa, partint de les necessitats del client i acabant quan aquestes estan satisfetes. En conclusió, a la finalització del present projecte s’obtindrà un SGI, amb tots els processos de l’empresa definits i implantats, que doni compliment a les normes UNEEN-ISO 9001:00, UNE-EN-ISO 14001:04 i OHSAS 18001:07. Aquest SGI, que s’ha realitzat des d’un punt de vista documental i teòric, suposarà una millora de l’eficàcia operativa dels processos i una important millora competitiva de l’empresa.

Spanish unemployment : normative versus analytical regionalisation procedures

In applied regional analysis, statistical information is usually published at different territorial levels with the aim providing inforamtion of interest for different potential users. When using this information, there are two different choices: first, to use normative regions ( towns, provinces, etc.) or, second, to design analytical regions directly related with the analysed phenomena. In this paper, privincial time series of unemployment rates in Spain are used in order to compare the results obtained by applying yoy analytical regionalisation models ( a two stages procedure based on cluster analysis and a procedure based on mathematical programming) with the normative regions available at two different scales: NUTS II and NUTS I. The results have shown that more homogeneous regions were designed when applying both analytical regionalisation tools. Two other obtained interesting results are related with the fact that analytical regions were also more estable along time and with the effects of scales in the regionalisation process

Incentives and promotion in wage hierarchies

Most of the large firms organization schemes consist in hierarchical structures of tiers with different wage levels. Traditionally the existence of this kind of organizations has been associated to the separation of productive and managerial or supervision tasks and to differences in the skills of the workers. However, many firms now employ workers with similar skills, and then the hierarchical structure can be related to an incentive scheme to ensure that workers supply effort. The model we present investigates how firm owners should determine the optimal wage distribution in order to maximize profits.

Activities of amino acid metabolizing enzymes in the stomach and small intestitine of developing rats

The activities of aspartate and alanine transaminase, serine dehydratase, arginase, glutamate dehydrogenase, adenylate deaminase and glutamine synthetase were determined in the stomach and small intestine of developing rats. Despite the common embryonic origin of the intestine and stomach, their enzymes showed quite different activity levels and patterns of development, depending on their roles. Most enzyme activities were low during late intrauterine life and after birth, attaining adult levels with the change of diet at weaning. No arginase activity was found in the stomach and no changes were detected in adenylate deaminase in the stomach or intestine throughout the period studied. Alanine transaminase, serine dehydratase and, to some extent, glutamine synthetase levels, significantly higher in late intrauterine life, decreased after birth, suggesting that the foetal stomach has a transient ability to handle amino acids.

A Gain Scheduling Model Predictive Controller for Blood Glucose Control in Type 1 Diabetes

This paper presents a control strategy for blood glucose(BG) level regulation in type 1 diabetic patients. To design the controller, model-based predictive control scheme has been applied to a newly developed diabetic patient model. The controller is provided with a feedforward loop to improve meal compensation, a gain-scheduling scheme to account for different BG levels, and an asymmetric cost function to reduce hypoglycemic risk. A simulation environment that has been approved for testing of artificial pancreas control algorithms has been used to test thecontroller. The simulation results show a good controller performance in fasting conditions and meal disturbance rejection, and robustness against model–patient mismatch and errors in mealestimation

Simultaneous determination of gross alpha, gross beta and Ra-226 in natural water by liquid scintillation counting.

The determination of gross alpha, gross beta and 226Ra activity in natural waters is useful in a wide range of environmental studies. Furthermore, gross alpha and gross beta parameters are included in international legislation on the quality of drinking water [Council Directive 98/83/EC].1 In this work, a low-background liquid scintillation counter (Wallac, Quantulus 1220) was used to simultaneously determine gross alpha, gross beta and 226Ra activity in natural water samples. Sample preparation involved evaporation to remove 222Rn and its short-lived decay daughters. The evaporation process concentrated the sample ten-fold. Afterwards, a sample aliquot of 8 mL was mixed with 12 mL of Ultima Gold AB scintillation cocktail in low-diffusion vials. In this study, a theoretical mathematical model based on secular equilibrium conditions between 226Ra and its short-lived decay daughters is presented. The proposed model makes it possible to determine 226Ra activity from two measurements. These measurements also allow determining gross alpha and gross beta simultaneously. To validate the proposed model, spiked samples with different activity levels for each parameter were analysed. Additionally, to evaluate the model's applicability in natural water, eight natural water samples from different parts of Spain were analysed. The eight natural water samples were also characterised by alpha spectrometry for the naturally occurring isotopes of uranium (234U, 235U and 238U), radium (224Ra and 226Ra), 210Po and 232Th. The results for gross alpha and 226Ra activity were compared with alpha spectrometry characterization, and an acceptable concordance was obtained.

eggNOG v4.0: nested orthology inference across 3686 organisms

With the increasing availability of various 'omics data, high-quality orthology assignment is crucial for evolutionary and functional genomics studies. We here present the fourth version of the eggNOG database (available at http://eggnog.embl.de) that derives nonsupervised orthologous groups (NOGs) from complete genomes, and then applies a comprehensive characterization and analysis pipeline to the resulting gene families. Compared with the previous version, we have more than tripled the underlying species set to cover 3686 organisms, keeping track with genome project completions while prioritizing the inclusion of high-quality genomes to minimize error propagation from incomplete proteome sets. Major technological advances include (i) a robust and scalable procedure for the identification and inclusion of high-quality genomes, (ii) provision of orthologous groups for 107 different taxonomic levels compared with 41 in eggNOGv3, (iii) identification and annotation of particularly closely related orthologous groups, facilitating analysis of related gene families, (iv) improvements of the clustering and functional annotation approach, (v) adoption of a revised tree building procedure based on the multiple alignments generated during the process and (vi) implementation of quality control procedures throughout the entire pipeline. As in previous versions, eggNOGv4 provides multiple sequence alignments and maximum-likelihood trees, as well as broad functional annotation. Users can access the complete database of orthologous groups via a web interface, as well as through bulk download.

Escuela, familia de origen inmigrante y participación

Las relaciones entre las familias y la escuela se inscriben en la articulación entre dos instituciones con asimetría de poder y en un contexto social y político que las sitúa en el debate entre intereses públicos y privados. Aunque deben considerarse espacios yuxtapuestos, a menudo lo que se percibe es la separación, la distancia, cuando no el conflicto, entre ambos. Y esto comporta que el territorio de la escuela y el de la familia se vigile, se controle, por la amenaza de invasión o intrusión. El artículo analiza la participación de los progenitores de origen inmigrante en la escuela en España.Realizando una breve referencia a la legislación, se centra en la situación organizativa confederal, federal y asociativa (utilizando como fuente de información datos propios obtenidos en cinco grupos de discusión organizados en los diferentes niveles organizativos) y, por último, se aproxima la realidad de las Asociaciones de Padres de Alumnos (a través de una encuesta a 594 presidentes de asociaciones).Además de constatar la baja participación general y, en particular, la de las familias de origen inmigrante (menor entre unos orígenes que entre otros) se evidencia la necesidad de trabajar para incorporarlos al movimiento de padres, hecho que se considera imprescindible para su desarrollo.
