Ideas, Possibilities and Limitations of Sustainable Economic Policy – the Example of Ecological Economics

A mesura que el suport del creixement econòmic constitueix un objectiu fonamental de la formulació de polítiques econòmiques, cal assenyalar que aquest tipus de creixement està limitat naturalment per un planeta finit. Aquest article argumenta que, des del punt de vista de la justícia intergeneracional, la realització d'un concepte de desmaterialització i, com a efecte, d'una economia que no creix (en el sentit de dissociació absoluta del creixement econòmic i consum d'energia i materials) es pot justificar. Per tant, el creixement pot ser també entesa com la millora de la qualitat de vida sobretot en comptes d'ampliar quantitats escarpats de sortida. Per tant, una dràstica reducció del cabal de material es necessita, sobretot en els països d'alts ingressos. Després de presentar alguns crítica de les propostes, en el focus d'aquest article es dibuixen en els arguments de per què la política econòmica en el futur han de ser etiquetats com "ecològic" i, a continuació, les opcions de posar en acció les idees del teòric presentat marc en tasques manejables polítiques seran discutides. En aquest cas, s'argumentarà que l'enfocament clàssic de internalització d'efectes externs sovint seguides de decisions de política econòmica ortodoxa no és completament capaç de reflectir canvis ecològics en les estructures de preus dels mercats. Per tant, formal (industrial i l'establiment de la política de consum) i institucions informals (llars) representen punts clau de la política econòmica sostenible, assenyalant l'individu com així com la responsabilitat col · lectiva per omplir aquest buit substancial.

A Clinical Decision Support using a Terminology Server to improve Patient Safety.

Clinical Decision Support Systems (CDSS) are software applications that support clinicians in making healthcare decisions providing relevant information for individual patients about their specific conditions. The lack of integration between CDSS and Electronic Health Record (EHR) has been identified as a significant barrier to CDSS development and adoption. Andalusia Healthcare Public System (AHPS) provides an interoperable health information infrastructure based on a Service Oriented Architecture (SOA) that eases CDSS implementation. This paper details the deployment of a CDSS jointly with the deployment of a Terminology Server (TS) within the AHPS infrastructure. It also explains a case study about the application of decision support to thromboembolism patients and its potential impact on improving patient safety. We will apply the inSPECt tool proposal to evaluate the appropriateness of alerts in this scenario.

Decision Support Methods for Global Optomization

Immobile location-allocation (LA) problems is a type of LA problem that consists in determining the service each facility should offer in order to optimize some criterion (like the global demand), given the positions of the facilities and the customers. Due to the complexity of the problem, i.e. it is a combinatorial problem (where is the number of possible services and the number of facilities) with a non-convex search space with several sub-optimums, traditional methods cannot be applied directly to optimize this problem. Thus we proposed the use of clustering analysis to convert the initial problem into several smaller sub-problems. By this way, we presented and analyzed the suitability of some clustering methods to partition the commented LA problem. Then we explored the use of some metaheuristic techniques such as genetic algorithms, simulated annealing or cuckoo search in order to solve the sub-problems after the clustering analysis

Four main virotypes among extended-spectrum-β-lactamase-producing isolates of Escherichia coli O25b:H4-B2-ST131: bacterial, epidemiological, and clinical characteristics.

A total of 1,021 extended-spectrum-β-lactamase-producing Escherichia coli (ESBLEC) isolates obtained in 2006 during a Spanish national survey conducted in 44 hospitals were analyzed for the presence of the O25b:H4-B2-ST131 (sequence type 131) clonal group. Overall, 195 (19%) O25b-ST131 isolates were detected, with prevalence rates ranging from 0% to 52% per hospital. Molecular characterization of 130 representative O25b-ST131 isolates showed that 96 (74%) were positive for CTX-M-15, 15 (12%) for CTX-M-14, 9 (7%) for SHV-12, 6 (5%) for CTX-M-9, 5 (4%) for CTX-M-32, and 1 (0.7%) each for CTX-M-3 and the new ESBL enzyme CTX-M-103. The 130 O25b-ST131 isolates exhibited relatively high virulence scores (mean, 14.4 virulence genes). Although the virulence profiles of the O25b-ST131 isolates were fairly homogeneous, they could be classified into four main virotypes based on the presence or absence of four distinctive virulence genes: virotypes A (22%) (afa FM955459 positive, iroN negative, ibeA negative, sat positive or negative), B (31%) (afa FM955459 negative, iroN positive, ibeA negative, sat positive or negative), C (32%) (afa FM955459 negative, iroN negative, ibeA negative, sat positive), and D (13%) (afa FM955459 negative, iroN positive or negative, ibeA positive, sat positive or negative). The four virotypes were also identified in other countries, with virotype C being overrepresented internationally. Correspondingly, an analysis of XbaI macrorestriction profiles revealed four major clusters, which were largely virotype specific. Certain epidemiological and clinical features corresponded with the virotype. Statistically significant virotype-specific associations included, for virotype B, older age and a lower frequency of infection (versus colonization), for virotype C, a higher frequency of infection, and for virotype D, younger age and community-acquired infections. In isolates of the O25b:H4-B2-ST131 clonal group, these findings uniquely define four main virotypes, which are internationally distributed, correspond with pulsed-field gel electrophoresis (PFGE) profiles, and exhibit distinctive clinical-epidemiological associations.

Statistical similarity between the compression of a porous material and earthquakes

It has been long stated that there are profound analogies between fracture experiments and earthquakes; however, few works attempt a complete characterization of the parallelisms between these so separate phenomena. We study the Acoustic Emission events produced during the compression of Vycor (SiO&sub&2&/sub&). The Gutenberg-Richter law, the modified Omori's law, and the law of aftershock productivity hold for a minimum of 5 decades, are independent of the compression rate, and keep stationary for all the duration of the experiments. The waiting-time distribution fulfills a unified scaling law with a power-law exponent close to 2.45 for long times, which is explained in terms of the temporal variations of the activity rate.

Empreendedorismo feminino e o conflito trabalho-família: estudo de multicasos no setor de comércio de material de construção da cidade de Curitiba

Os autores que analisam o conflito trabalho-família têm ressaltado a importância da busca do equilíbrio do tempo na dedicação para o trabalho sem que haja detrimento do tempo dedicado à família. Destacam-se três dimensões em que se podem encontrar conflitos entre o trabalho e a família: tempo, tensão e comportamento. Nesta pesquisa, tem-se como objetivo apresentar os conflitos trabalho-família percebidos por duas empresárias do setor de comércio de material de construção da cidade de Curitiba, bem como as ações dessas empresárias para lidarem com os conflitos identificados. Por meio de pesquisa qualitativa, do tipo estudo de multicasos, foram entrevistados tanto as empresárias quanto seus parceiros. Os achados da pesquisa corroboram os estudos citados na revisão teórica, sendo o fator tempo o mais frequentemente citado como gerador de conflitos trabalho-família e o controle emocional como a ação mais citada como atenuante desses mesmos conflitos.

Estudi del comportament de materials nanoestructurats en el tractament d'aigües contaminades amb arsènic

El SPION (Super Paramagnetic Iron Oxide Nanoparticles) ha estat estudiat com un nou adsorbent per eliminar l’arsènic d’aigües contaminades. Les condicions òptimes de treball es van assolir per un pH de 3,6 i per concentracions inferiors als 100ppm. No es van trobar interferències significatives produïdes pels cations Cu, Ni i Zn en l’adsorció de l’As, sent el fosfat l’anió que més interfereix. Una esponja de cel·lulosa s’ha utilitzat com a suport del SPION, per disminuir les agregacions de les nanopartícules en suspensió i per proporcionar una material adequat per l’adsorció en continu, experiment amb columnes. Així, es va obtenir un augment de la capacitat d’adsorció del SPION per l’As(V), mentre que per l’As(III) continua sent baixa, per tant s’augmenta la selectivitat per l’As(V). Les interferències aniòniques afecten d’igual manera a l’adsorció de l’As(III) i l’As(V) quan l’adsorció és en continu o en discontinu. Els cations metàl·lics no interfereixen en l’adsorció de l’arsènic, a excepció del coure que és adsorbit i porta a la disminució de l’adsorció d’arsènic.

A enfermagem frente a acidentes de trabalho com material potencialmente contaminado na era do HIV

Realizou-se esta investigação, com os objetivos de identificar a ocorrência de acidentes de trabalho com material pérfuro-cortante potencialmente contaminado, entre enfermeiros e auxiliares de enfermagem de um Hospital de ensino geral do interior do Estado de São Paulo; relacionar a ocorrência destes acidentes com a categoria profissional e anos de trabalho na instituição; identificar o tipo de material pérfuro-cortante causador do acidente e identificar as condutas tomadas após o acidente, pelo acidentado. Para a coleta de dados, através de entrevista individual, utilizou-se um formulário estruturado onde registrava-se, a causa atribuída ao acidente, o período de atuação do profissional acidentado, o objeto causador, a conduta tomada após o acidente. Evidenciou-se que as Precauções Padrão ou as antigas Precauções Universais não são utilizadas como deveriam, conferindo portanto, risco à equipe de enfermagem. Considera-se que esta equipe necessita de orientações específicas através de educação continuada sobre o assunto.

Tax incentives and direct support for R&D: What do firms use and why?

This paper studies whether firms' use of R&D subsidies and R&D tax incentives is correlated to two sources of underinvestment in R&D, financing constraints and appropriability. We find that financially constrained SMEs are less likely to use R&D tax credits and more likely to obtain subsidies. SMEs using legal methods to protect their intellectual property are more likely to use tax incentives. Results are ambiguous for large firms. For both having previous experience in R&D increases the likelihood of using tax incentives, while it reduces the likelihood of using exclusively subsidies, suggesting that the latter induce entry into R&D. Results imply that direct funding and tax credits do not have the same ability to address each source of R&D underinvestment, and that on average subsidies may be better suited than tax credits at least for SMEs. From a policy perspective these tools may be complements rather than substitutes.
