    Correlation equalities and upper bounds for the transverse Ising model

    Full text link
    Starting from an exact formal identity for the two-state transverse Ising model and using correlation inequalities rigorous upper bounds for the critical temperature and the critical transverse field are obtained which improve effective results.Comment: 8 pages, 1 figur

    Perspectives of the Internal Public in a Cultural Event: the Case of Noc Noc, Guimar√£es - Portugal

    Get PDF
    Given the significant impact that cultural events may have in local communities and the inherent organization complexity, it is important to understand their specificities. Most of the times cultural events disregard marketing and often marketing is distant from art. Thus an analysis of an inside perspective might bring significant returns to the organization of such an event. This paper considers the three editions (2011, 2012 and 2013) of a cultural event ‚Äď Noc Noc ‚Äď organized by a local association in the city of Guimar√£es, Portugal. Its format is based in analogous events, as Noc Noc intends to convert everyday spaces (homes, commercial outlets and a number of other buildings) into cultural spaces, processed and transformed by artists, hosts and audiences. By interviewing a sample of people (20) who have hosted this cultural event, sometimes doubling as artists, and by experiencing the three editions of the event, this paper illustrates how the internal public understands this particular cultural event, analyzing specifically their motivations, ways of acting and participating, as well as their relationship with the public, with the organization of the event and with art in general. Results support that artists and hosts motivations must be identified in a timely and appropriate moment, as well as their views of this particular cultural event, in order to keep them participating, since low budget cultural events such as this one may have a key role in small scale cities

    Tendências de Foodservice e o estilo de vida dos turistas: novas tendências em turismo

    Food and catering are an ever-changing industry that influences, and it is influenced by the lives of millions of people in the world. The products and services provided by this business are constantly adapting to the influencing variables that are on-growing. Actually, consumers create the tendencies and are incredibly demanding on what they want and do not want. Tourists as consumers seek products that can adapt to your lifestyle. Therefore, in the foodservice field, restaurants are required to adapt to different variables, such as specific diets and trendy new tastes, while keeping their own characteristics. In addition, the numerous social media platforms have changed this industry completely. Restaurants have to focus on the new technology-savvy generations. This study seeks to understand the impact that the lifestyle changes from the last years and the Web 2.0 had in the field. Who creates the tendencies? Why and how are restaurants and food distributors adapting to the new needs of the market? In order to answer these questions, the 2015 and 2016 tendencies for the foodservice fields are analyzed. Findings help destination and restaurants managers to adapt and change their products and service.info:eu-repo/semantics/publishedVersio

    This paper appears in International Journal of Information and Communication Technology Education edited by Lawrence A. Tomei (Ed.) Copyright 2007, IGI Global, www.igi-global.com. Posted by permission of the publisher. URL:http://www.idea-group.com/journals/details.asp?id=4287.The development of a knowledge-based society needs a technological infrastructure and a workforce with the necessary knowledge and competences, supported by a well-structured initial education and a continuous learning program, available to all citizens, including those who did not have the opportunity to attend Higher Education (HE) when they were younger. We recognize that these students may be rich in experience but they also have some difficulties in adapting to the pedagogical approaches of learning and teaching. Furthermore, their attitudes and problems are not necessarily the same as those of traditional students but they are still expected to fit into educational institutions designed for younger students. The project LIHE ‚Äď Learning in Higher Education aimed to improve the learning experience and environment of adults, particularly non-traditional adults as well as to promote lifelong learning in HE, within a European dimension. In this paper we will present this project together with some of the results

    Selection of low swelling materials for protein adsorption from white wines

    Get PDF
    The protein adsorption capacity of different materials was evaluated to assess their potential efficacy as alternative adsorbents for the removal of proteins from wines, with the purpose of finding suitable low-swelling materials that could be used in a percolated bed. The adsorbents tested were thermally treated sodium bentonite, low-swelling adsorbing clays, ion exchange resins and other protein adsorbents (silica gel, hydroxyapatite and alumina). The materials were evaluated by analysing both the capacity to stabilize untreated white wines, according to a heat test, and by characterizing the adsorption isotherms of bovine serum albumin (BSA) in a model wine (water, ethanol and K-bitartrate). Breakthrough curves in a packed bed were determined experimentally for some materials, showing the influence of the adsorption isotherm shape. Some ionexchange resins showed a favourable behaviour and have good potential as alternative adsorbents

    Effectiveness of Psycho-Educational Intervention in HIV Patients' Treatment

    Adherence to Highly Active Antiretroviral Therapy (HAART) is the main prognostic factor associated with HIV disease progression and death. The aim was to evaluate the effectiveness of a psycho-educational program to promote adherence to HAART in HIV patients. A longitudinal study (n‚ÄČ=‚ÄČ102) over 9‚ÄČmonths in an Infectious Diseases Hospital was carried out. Adherence to HAART was measured with standardized scales and values of viral load. Two groups were defined: adherents and non-adherents. In the latter, a psycho-educational program was implemented and 6‚ÄČmonths later measured adherence to HAART. Knowledge about the infection, CD4 T lymphocytes and HIV-ribonucleic acid values were measured before and after this program. The sample was predominantly male (70%), heterosexual (78%), with a mean age of 49 (SD‚ÄČ=‚ÄČ12.7) years, and 48% of participants were not adhering to HAART. After the program, non-adherence decreased to 21.6%. Knowledge about the infection increased from 79 to 97%. A significant increase in CD4 T lymphocytes (mean 540-580) and a decrease in viral load (mean 5411-3052) were observed, the latter of statistical significance. This program seems to be feasible and efficient, improving adherence to HAART
