Cámaras de Comercio: comparativa entre la Cámara de Comercio de Barcelona y la Cámara de Comercio Española en Gran Bretaña

Les Cambres de Comerç son corporacions de dret públic que realitzen funcions de caràcter consultiu i de col·laboració amb les Administracions Públiques. En l’actual context econòmic han adquirit una especial rellevància de cara a la regeneració del teixit econòmic i la creació de llocs de treball i es consolida la seva finalitat de representació, promoció i defensa dels interessos generals del comerç, així com la prestació de serveis a totes les empreses. Aquestes institucions van néixer a Espanya a finals del segle XIX, concretament a l’any 1886, amb l’ intenció de representar els interessos generals de les empreses. Les Cambres seguien un model cameral continental caracteritzat per l’obligatorietat en l’adscripció de les persones que exercien activitats empresarials amb el corresponent pagament de quotes. El recurs cameral representava la principal font d’ingressos de les Cambres, pel que l’entrada en vigor del Reial Decret 13/2010 que eliminava l’obligatorietat del pagament de la quota a les empreses va provocar un canvi molt important de les seves funcions. El legislador va introduir aquest canvi per dos motius. Per una banda, tenia com objectiu impulsar a les Cambres com entitats de prestació de serveis amb la finalitat de reforçar la seva eficiència en el desenvolupament de les funcions que se l’hi atribuïen. I per altra, considerava que l’eliminació d’aquesta obligatorietat faria que les empreses disposessin de més recursos en la difícil situació econòmica existent. Les Cambres de Comerç van haver d’adaptar-se a aquesta nova situació i intentar aconseguir els recursos econòmics suficients per la seva subsistència. Dos bons exemples son la Cambra de Comerç de Barcelona i la Cambra de Comerç Espanyola de Gran Bretanya que, mitjançant una proposta de serveis d’alta qualitat, com els serveis d’internacionalització o els serveis de consultoria, estan captant a un gran nombre d’empreses. La realitat en la que ens trobem és que certament les Cambres de Comerç, tant les que estan domiciliades en el territori nacional com les que estan establertes a l’estranger, estan oferint uns serveis molt importants per a les petites i mitjanes empreses en l’àmbit de la internacionalització i augment de la seva competitivitat. La seva experiència, el seu coneixement, el seu gran equip de treball i les seves col·laboracions amb altres entitats són elements diferencials d’aquestes corporacions que faciliten a les empreses el procés d’iniciar la seva expansió a noves línies de negoci o a nous mercats amb les màximes garanties.

Care delivery value chains for ophthalmic clinics in Switzerland

Perceived patient value is often not aligned with the emerging expenses for health care services. In other words, the costs are often supposed as rising faster than the actual value for the patients. This fact is causing major concerns to governments, health plans, and individuals. Attempts to solve the problem have habitually been on the operational effectiveness side: increasing patient volume, minimizing costs, rationing, or closing hospitals, usually resulting in a zero-sum game. Only few approaches come from the strategic positioning side and "competition" among hospitals is still perceived rather as a danger than as a chance to create a positive-sum game and stimulate patient value. In their 2006 book, "Redefining Health Care", the renowned Harvard strategy professor Michael E. Porter and hospital management expert Professor Elizabeth Olmsted Teisberg approach the challenge from the positive-sum perspective: they propose to form Integrated Practice Units (IPUs) and manage hospitals in a modern, patient value oriented way. They argue that creating value-based competition on results should have the same effect on the health care sector like transparency and competition turned other industries with out-dated management models (like recently the inert telecommunication industry) into highly competitive and customer value creating businesses. The objective of this paper is to elaborate Care Delivery Value Chains for Integrated Practice Units in ophthalmic clinics and gather a first feedback from Swiss hospital managers, ophthalmologists, and patients, if such an approach could be a realistic way to improve health care management. First, Porter's definition of competitiveness (distinction between operational effectiveness and strategic positioning) is explained. Then, the Care Delivery Value Chain is introduced as a key element for understanding value-based management, followed by three practice examples for ophthalmic clinics. Finally, recommendations are given how the Care Delivery Value Chain can be managed efficiently and how the obstacles of becoming a patient-oriented organization can be overcome. The conclusion is that increased transparency and value-based competition on results has the potential to change the mindset of hospital managers-which will align patient value with the emerging health care expenses. Early adapters of this management approach will gain a competitive advantage. [Author, p. 6]

Possible new ways in the pharmacological treatment of bipolar disorder and comorbid alcoholism.

Possible new ways in the pharmacological treatment of bipolar disorder and comorbid alcoholism. Azorin JM, Bowden CL, Garay RP, Perugi G, Vieta E, Young AH. Source Department of Psychiatry, CHU Sainte Marguerite, Marseilles, France. Abstract About half of all bipolar patients have an alcohol abuse problem at some point of their lifetime. However, only one randomized, controlled trial of pharmacotherapy (valproate) in this patient population was published as of 2006. Therefore, we reviewed clinical trials in this indication of the last four years (using mood stabilizers, atypical antipsychotics, and other drugs). Priority was given to randomized trials, comparing drugs with placebo or active comparator. Published studies were found through systematic database search (PubMed, Scirus, EMBASE, Cochrane Library, Science Direct). In these last four years, the only randomized, clinically relevant study in bipolar patients with comorbid alcoholism is that of Brown and colleagues (2008) showing that quetiapine therapy decreased depressive symptoms in the early weeks of use, without modifying alcohol use. Several other open-label trials have been generally positive and support the efficacy and tolerability of agents from different classes in this patient population. Valproate efficacy to reduce excessive alcohol consumption in bipolar patients was confirmed and new controlled studies revealed its therapeutic benefit to prevent relapse in newly abstinent alcoholics and to improve alcohol hallucinosis. Topiramate deserves to be investigated in bipolar patients with comorbid alcoholism since this compound effectively improves physical health and quality of life of alcohol-dependent individuals. In conclusion, randomized, controlled research is still needed to provide guidelines for possible use of valproate and other agents in patients with a dual diagnosis of bipolar disorder and substance abuse or dependence.

Towards a Network Government? A critical analysis of current assessment methods for e-Government

Contemporary public administrations have become increasingly more complex, having to cordinate actions with emerging actors in the public and the private spheres. In this scenario the modern ICTs have begun to be seen as an ideal vehicle to resolve some of the problems of public administration. We argue that there is a clear need to explore the extent to which public administrations are undergoing a process of transformation towards a netowork government linked to the systematic incorporation of ICTs in their basic activities. Through critically analysing a selection of e-government evaluation reports, we conclude that research should be carried out if we are to build a solid government assessment framework based on network-like organisation characteristics.

Recomendaciones de manipulación doméstica de frutas y hortalizas para preservar su valor nutritivo

El beneficio para la salud del consumo diario de al menos 5 raciones entre frutas y hortalizas está bien documentado. En España no se alcanzan los 600 gramos por persona y día que recomienda la Organización Mundial de la Salud (OMS) en sus objetivos de salud pública, por lo que es importante mejorar el acceso a estos alimentos, aprovechar su potencial nutritivo y salvar las barreras para su consumo. Los objetivos de este documento son: facilitar la toma de decisiones responsables con la salud; aprovechar al máximo el valor nutritivo de frutas y hortalizas; ayudar a salvar las barreras para su consumo e informar sobre cómo afecta la conservación, manipulación y cocinado domésticos a su valor nutritivo. Para minimizar la pérdida de nutrientes y mejorar su biodisponibilidad durante la manipulación de frutas y hortalizas, la Asociación para la promoción del consumo de frutas y hortalizas"5 al día" (España) recomienda: evitar almacenamientos prolongados en el refrigerador; aprovechar las capas y hojas exteriores; pelar y/o cortar el alimento justo antes de consumirlo; lavar las piezas enteras y trocearlas posteriormente; controlar el tiempo de remojo de las piezas cortadas; preferir técnicas de cocinado que no requieran contacto directo con el agua; a menor tiempo de cocción, menor pérdida de nutrientes; la fritura correcta conserva muy bien los nutrientes, aunque no debe abusarse de esta técnica; añadir un chorrito de vinagre o de zumo de limón al agua de cocción; aprovechar el agua de los vegetales cocidos para elaborar otros alimentos (ej.: salsas, sopas, purés, etc.), excepto la de acelgas, espinacas o remolacha. La Asociación"5 al día" recomienda aumentar el consumo de frutas y hortalizas, y considera que la pérdida de nutrientes durante su manipulación doméstica no debe entenderse como una barrera para su consumo.

Vacancy-assisted domain-growth in asymmetric binary alloys: A Monte Carlo Study

A Monte Carlo simulation study of the vacancy-assisted domain growth in asymmetric binary alloys is presented. The system is modeled using a three-state ABV Hamiltonian which includes an asymmetry term. Our simulated system is a stoichiometric two-dimensional binary alloy with a single vacancy which evolves according to the vacancy-atom exchange mechanism. We obtain that, compared to the symmetric case, the ordering process slows down dramatically. Concerning the asymptotic behavior it is algebraic and characterized by the Allen-Cahn growth exponent x51/2. The late stages of the evolution are preceded by a transient regime strongly affected by both the temperature and the degree of asymmetry of the alloy. The results are discussed and compared to those obtained for the symmetric case.

Prediction of Antibacterial Activity from Physicochemical Properties of Antimicrobial Peptides

Consensus is gathering that antimicrobial peptides that exert their antibacterial action at the membrane level must reach a local concentration threshold to become active. Studies of peptide interaction with model membranes do identify such disruptive thresholds but demonstrations of the possible correlation of these with the in vivo onset of activity have only recently been proposed. In addition, such thresholds observed in model membranes occur at local peptide concentrations close to full membrane coverage. In this work we fully develop an interaction model of antimicrobial peptides with biological membranes; by exploring the consequences of the underlying partition formalism we arrive at a relationship that provides antibacterial activity prediction from two biophysical parameters: the affinity of the peptide to the membrane and the critical bound peptide to lipid ratio. A straightforward and robust method to implement this relationship, with potential application to high-throughput screening approaches, is presented and tested. In addition, disruptive thresholds in model membranes and the onset of antibacterial peptide activity are shown to occur over the same range of locally bound peptide concentrations (10 to 100 mM), which conciliates the two types of observations

Inhibition of nociceptive responses after systemic administration of amidated kyotorphin

BACKGROUND AND PURPOSE Kyotorphin (KTP; L-Tyr-L-Arg), an endogenous neuropeptide, is potently analgesic when delivered directly to the central nervous system. Its weak analgesic effects after systemic administration have been explained by inability to cross the blood-brain barrier (BBB) and detract from the possible clinical use of KTP as an analgesic. In this study, we aimed to increase the lipophilicity of KTP by amidation and to evaluate the analgesic efficacy of a new KTP derivative (KTP-amide - KTP-NH 2). EXPERIMENTAL APPROACH We synthesized KTP-NH 2. This peptide was given systemically to assess its ability to cross the BBB. A wide range of pain models, including acute, sustained and chronic inflammatory and neuropathic pain, were used to characterize analgesic efficacies of KTP-NH 2. Binding to opioid receptors and toxicity were also measured. KEY RESULTS KTP-NH 2, unlike its precursor KTP, was lipophilic and highly analgesic following systemic administration in several acute and chronic pain models, without inducing toxic effects or affecting motor responses and blood pressure. Binding to opioid receptors was minimal. KTP-NH 2 inhibited nociceptive responses of spinal neurons. Its analgesic effects were prevented by intrathecal or i.p. administration of naloxone. CONCLUSIONS AND IMPLICATIONS Amidation allowed KTP to show good analgesic ability after systemic delivery in acute and chronic pain models. The indirect opioid-mediated actions of KTP-NH 2 may explain why this compound retained its analgesic effects although the usual side effects of opioids were absent, which is a desired feature in next-generation pain medications
