In this paper we highlight the importance of the operational costs in explaining economic growth and analyze how the industrial structure affects the growth rate of the economy. If there is monopolistic competition only in an intermediate goods sector, then production growth coincides with consumption growth. Moreover, the pattern of growth depends on the particular form of the operational cost. If the monopolistically competitive sector is the final goods sector, then per capita production is constant but per capita effective consumption or welfare grows. Finally, we modify again the industrial structure of the economy and show an economy with two different growth speeds, one for production and another for effective consumption. Thus, both the operational cost and the particular structure of the sector that produces the final goods determines ultimately the pattern of growth.

In this article we extend the rational partisan model of Alesina and Gatti (1995) to include a second policy, fiscal policy, besides monetary policy. It is shown that, with this extension, the politically induced variance of output is not always eliminated nor reduced by delegating monetary policy to an independent and conservative central bank. Further, in flation and output stabilisation will be affected by the degree of conservativeness of the central bank and by the probability of the less in flation averse party gaining power. Keywords: rational partisan theory; fiscal policy; independent central bank JEL Classi fication: E58, E63.

Aquest projecte pretén donar un impuls a una tecnologia de generació elèctrica per a comunitats aïllades de l’Amazònia equatoriana i regions semblants. Aquestes són zones rurals on la densitat de població és molt baixa i dispersa, que solen tindre petits consums d’energia. Així la provisió d’aquesta des de centres de generació llunyans requereix d’un transport desmesurat. Com a conseqüència d’aquesta situació desfavorable molta gent no pot disposar d’electricitat.La font d’il•luminació més utilitzada són les espelmes, els encenedors de querosè i els llums de gas. Aquests tenen deficient intensitat lluminosa, el seu ús habitual provoca danys a la vista i pulmons, i és causa d’incendis. En algunes ocasions es fa ús de generadors diesel que a part del soroll, així com les altres solucions esmentades, depèn de la provisió de les ciutats allunyades. En els últims anys s’han introduït sistemes fotovoltaics domiciliaris que han demostrat ser una alternativa eficaç. En qualsevol cas el cost de l’energia resulta molt elevat per tals regions.La solució adoptada ha sigut una turbina Darrieus de D=1,5 i L=1,5, amb 6 àleps NACA 0018 inclinats 8 graus cap a fora, amb una corda de 0,22 m, a un regim de 2,67 rad/s, que correspon a un rati de velocitats de TSR=2 quan el riu baixa a 1m/s. Aquesta pot treballar en un rang de velocitats de 0,8 a 1,2 m/s com són les velocitats habituals registrades al riu Napo, emplaçament indicat per a la construcció d’una turbina pilot

OBJECTIVES: Polypharmacy is one of the main management issues in public health policies because of its financial impact and the increasing number of people involved. The polymedicated population according to their demographic and therapeutic profile and the cost for the public healthcare system were characterised. DESIGN: Cross-sectional study. SETTING: Primary healthcare in Barcelona Health Region, Catalonia, Spain (5 105 551 inhabitants registered). PARTICIPANTS: All insured polymedicated patients. Polymedicated patients were those with a consumption of ≥16 drugs/month. MAIN OUTCOMES MEASURES: The study variables were related to age, gender and medication intake obtained from the 2008 census and records of prescriptions dispensed in pharmacies and charged to the public health system. RESULTS: There were 36 880 polymedicated patients (women: 64.2%; average age: 74.5±10.9 years). The total number of prescriptions billed in 2008 was 2 266 830 (2 272 920 total package units). The most polymedicated group (up to 40% of the total prescriptions) was patients between 75 and 84 years old. The average number of prescriptions billed monthly per patient was 32±2, with an average cost of 452.7±27.5. The total cost of those prescriptions corresponded to 2% of the drug expenditure in Catalonia. The groups N, C, A, R and M represented 71.4% of the total number of drug package units dispensed to polymedicated patients. Great variability was found between the medication profiles of men and women, and between age groups; greater discrepancies were found in paediatric patients (5-14 years) and the elderly (≥65 years). CONCLUSIONS: This study provides essential information to take steps towards rational drug use and a structured approach in the polymedicated population in primary healthcare.

The aim of this research paper is to present a macroscopic study about the feasibility and the efficiency of mobile devices in computing Least-Cost Path (LCP). This kind of artifact must work in off-line mode and must allow to load data from a mountain zone like digital terrain models and meteorological data.The research strategy has two steps:- First of all, we need to identify the set of software components in order to implement them inside the IT artifact. This set of components should have to be able to do LCP calculations, visualize results and present a well adapted human interface. The main goal of this first steep is to demonstrate the feasibility of a mobile geographic information system by following the ¿Design & Creation¿ research strategy.- In a second time, the goal is to evaluate the reliability and usability of this IT artifact by an ¿Experiments¿ research approach. In this step we want to characterize the behavior of the artifact in terms of fidelity and LCP process speed. This evaluation will be carried out by some external users.During the reading of this paper, we will see that this kind of geographic information system (the IT artifact) has the minimal requirements needed to carry out LCP calculations in mobile devices although it has several limitations and constraints in terms of useability and reliability. We will point out qualitative and quantitative elements related to the IT artifact performances while doing this kind of computations.

L’objectiu projecte és desenvolupar un sistema d’ajut al guiatge universal adaptable a qualsevol vehicle que permeti incrementar significativament l’eficiència de les feines a realitzar per la maquinària al camp. El sistema proposat es pot configurar d’acord amb les característiques de la maquinària o de la tasca a realitzar i és capaç de guiar en línia recta i crear paral·leles a la passada recta de referència. Un altre objectiu és millorar el rendiment, la fiabilitat i la usabilitat del programari de monitoratge inicial instal·lat al tractor, com també caracteritzar el receptor GPS AgGPS 332 de Trimble® per a comprovar la precisió de l’aparell. Els resultats obtinguts en la millora del programa de monitoratge són molt satisfactoris a l’haver corregit imprecisions de funcionament que en limitaven l’usabilitat. Els resultats obtinguts en la caracterització del receptor AgGPS 332 permeten valorar millor quin tipus de correcció diferencial és més convenient per a la precisió de treball requerida segons el seu cost de posada en marxa i de funcionament.Els resultats obtinguts en la validació de l’ajut al guiatge, han validat el guiatge a 10 metres vista com un ajut al guiatge equivalent al guiatge manual quan la velocitat de treball és de 5 km/h, el tractorista té referències visuals i no està fatigat. Els resultats obtinguts pels guiatges a 3 i 50 metres no són satisfactoris a 5 km/h. Tanmateix, durant el procés de disseny, la realització dels assajos i durant l’anàlisi de resultats s’han identificat algunes mancances i limitacions i es proposen una sèrie de millores per tal de solucionar-les.

El consum de tabac és causa de pèrdua de salut i la primera causa de mort prematura prevenible en els països desenvolupats. Deixar de fumar aporta grans beneficis per a la salut però hi ha un fet que fa que moltes persones es plantegin no deixar aquest hàbit i és la preocupació pel guany ponderal. Diversos estudis consultats apunten a que es produeix un guany mig de 3-4 kg durant el procés de deshabituació tot i que en un percentatge considerable pot ser superior. Les causes d’aquest guany de pes són degudes a diversos factors: recuperació dels sentits del gust i l’olfacte, l’ansietat, la falta d’activitat física i sobre tot el paper que juga la nicotina. La nicotina augmenta la despesa energètica en l’activitat física, augmenta la termogènesi, incrementa el metabolisme basal, inhibeix la gana, produeix pèrdua de pes, afavoreix el buidament gàstric i recentment s’ha vist en rosegadors que la nicotina regula mecanismes cerebrals a nivell del hipotàlem, això ho fa perquè actua inactivant l’acció de l’enzim adenosine 5′-monophosphate-activated protein kinase (AMPK) provocant una pèrdua de la gana i un augment de la despesa energètica al incrementar la temperatura corporal i accelerar el metabolisme de les grasses. Explicar que la majoria dels efectes tenen una base bioquímica pot ajudar al pacient a comprendre la simptomatologia que pateix en el procés de la deshabituació tabàquica.

Background: Breast cancer (BC) causes more deaths than any other cancer among women in Catalonia. Early detection has contributed to the observed decline in BC mortality. However, there is debate on the optimal screening strategy. We performed an economic evaluation of 20 screening strategies taking into account the cost over time of screening and subsequent medical costs, including diagnostic confirmation, initial treatment, follow-up and advanced care. Methods: We used a probabilistic model to estimate the effect and costs over time of each scenario. The effect was measured as years of life (YL), quality-adjusted life years (QALY), and lives extended (LE). Costs of screening and treatment were obtained from the Early Detection Program and hospital databases of the IMAS-Hospital del Mar in Barcelona. The incremental cost-effectiveness ratio (ICER) was used to compare the relative costs and outcomes of different scenarios. Results: Strategies that start at ages 40 or 45 and end at 69 predominate when the effect is measured as YL or QALYs. Biennial strategies 50-69, 45-69 or annual 45-69, 40-69 and 40-74 were selected as cost-effective for both effect measures (YL or QALYs). The ICER increases considerably when moving from biennial to annual scenarios. Moving from no screening to biennial 50-69 years represented an ICER of 4,469€ per QALY. Conclusions: A reduced number of screening strategies have been selected for consideration by researchers, decision makers and policy planners. Mathematical models are useful to assess the impact and costs of BC screening in a specific geographical area.

Background: Non-adherence to antidepressants generates higher costs for the treatment of depression. Little is known about the cost-effectiveness of pharmacist's interventions aimed at improving adherence to antidepressants. The study aimed to evaluate the cost-effectiveness of a community pharmacist intervention in comparison with usual care in depressed patients initiating treatment with antidepressants in primary care. Methods: Patients were recruited by general practitioners and randomized to community pharmacist intervention (87) that received an educational intervention and usual care (92). Adherence to antidepressants, clinical symptoms, Quality-Adjusted Life-Years (QALYs), use of healthcare services and productivity losses were measured at baseline, 3 and 6 months. Results: There were no significant differences between groups in costs or effects. From a societal perspective, the incremental cost-effectiveness ratio (ICER) for the community pharmacist intervention compared with usual care was 1,866 for extra adherent patient and 9,872 per extra QALY. In terms of remission of depressive symptoms, the usual care dominated the community pharmacist intervention. If willingness to pay (WTP) is 30,000 per extra adherent patient, remission of symptoms or QALYs, the probability of the community pharmacist intervention being cost-effective was 0.71, 0.46 and 0.75, respectively (societal perspective). From a healthcare perspective, the probability of the community pharmacist intervention being cost-effective in terms of adherence, QALYs and remission was of 0.71, 0.76 and 0.46, respectively, if WTP is 30,000. Conclusion: A brief community pharmacist intervention addressed to depressed patients initiating antidepressant treatment showed a probability of being cost-effective of 0.71 and 0.75 in terms of improvement of adherence and QALYs, respectively, when compared to usual care. Regular implementation of the community pharmacist intervention is not recommended.

Pensions together with savings and investments during active life are key elements of retirement planning. Motivation for personal choices about the standard of living, bequest and the replacement ratio of pension with respect to last salary income must be considered. This research contributes to the financial planning by helping to quantify long-term care economic needs. We estimate life expectancy from retirement age onwards. The economic cost of care per unit of service is linked to the expected time of needed care and the intensity of required services. The expected individual cost of long-term care from an onset of dependence is estimated separately for men and women. Assumptions on the mortality of the dependent people compared to the general population are introduced. Parameters defining eligibility for various forms of coverage by the universal public social care of the welfare system are addressed. The impact of the intensity of social services on individual predictions is assessed, and a partial coverage by standard private insurance products is also explored. Data were collected by the Spanish Institute of Statistics in two surveys conducted on the general Spanish population in 1999 and in 2008. Official mortality records and life table trends were used to create realistic scenarios for longevity. We find empirical evidence that the public long-term care system in Spain effectively mitigates the risk of incurring huge lifetime costs. We also find that the most vulnerable categories are citizens with moderate disabilities that do not qualify to obtain public social care support. In the Spanish case, the trends between 1999 and 2008 need to be further explored.

En el present treball es proposa com lluitar contra el malbaratament alimentari que es genera al llarg de tota la cadena alimentària, sent aquest degut a causa d'una planificació poc adequada. L'objectiu principal és planificar i implantar un sistema de gestió per tal de recuperar l'excedent alimentari que es genera als comerços i les indústries del municipi de Montmeló, elaborant així un protocol per tal de poder redistribuir aquest aliment als sectors de la població en situacions econòmiques més precàries. Com a objectius secundaris, es pretén conscienciar, fomentar i potenciar el treball en xarxa entre els diferents agents implicats, com ara: la ciutadania, les entitats socials (Càritas Parroquial Montmeló), sector privat (establiments alimentaris del municipi, mercat municipal, indústries del sector alimentari) i el sector públic (departament de serveis socials, medi ambient, comerç i brigada municipal). A l'hora de planificar i implantar un sistema de gestió per tal de recuperar l'excedent alimentari, s'ha analitzat i valorat el camí que hi realitza, des d'on es genera fins al beneficiari final. Aquest s'ha gestionat per etapes, en les que s'han identificat els generadors, el tipus i quantitat d'aliment que malbaraten. S'ha proposat un nou sistema de recollida d'informació i les pautes que han de seguir per garantir el bon estat de l'aliment com: una taula de conservació, un protocol de funcionament, un document d'entrega i una fitxa de control de les condicions d'higiene. Per tal d'assolir una bona coordinació entre totes les parts, s'han realitzat reunions conjuntes entre els generadors, serveis socials i Càritas on s'ha acabat signant un acord de col·laboració. Entre les conclusions més rellevants cal destacar que ha servit per establir un precedent d'aprofitament alimentari al municipi de Montmeló, aconseguint alimentar a un gran nombre de famílies amb greus problemes econòmics. A més s'ha arribat a disminuir la quantitat de residus generats, amb el conseqüent estalvi de recursos econòmics i materials on s'ha recuperat un total de 5.760 Kg d'aliments aptes pel consum.
