Perception of poverty .Individual, household and social enviromental determinants

People’s perception of their own well-being depends on, among other factors, the household level of income and wealth, the respondent’s socio-economic characteristics (sex, age, employment status, etc..) and social capital endowment of household place of residence (Sen A., 1985, The Standard of Living. The Tanner Lectures, Cambridge University Press, Cambridge). However, limited attention has been dedicated to understanding to what extent people’s perception of their own well-being is influenced by social capital endowment of household place of residence. Interest in this type of problem arises from the need to highlight to what extent subjective perception of well-being depends on individual and family socio-economic conditions and to what extent it depends on the characteristics of the local context of where the family lives. Such evidence would help the central and local authorities and economic operators to choose the appropriate socio-economic measures in order to improve household living conditions. Hence, this research aims to answer the following questions: i) To what extent subjective well-being is affected by respondent's socio-economic characteristics, by household economic conditions and by social capital endowment of household place of residence? ii) Which of the social capital components (Social Behaviour, Social Relationships, Social Engagement, Civic Responsibility, Territorial Characteristics) has a higher impact on subjective well-being and can be regarded as primary risk factor of family poverty status? In order to purse this aim , the ordered probit model will be used to analyse answers to the following question taken from the Survey on Household Income and Wealth (SHIW) of the Bank of Italy Considering your monthly disposable income, is your household able to make ends meet: (1) with great difficulty, (2) with difficulty, (3) with some difficulty, (4) without difficulty, (5) with ease, (6) with great ease? The explanatory variables x are grouped as following: 1. Respondent’s socio-economic characteristics; 2. Household socio-economic characteristics; 3. Social capital endowment of household place of residence. and we adopt the definition of social capital suggested by the World Bank Social Capital Initiative research group “The social capital […] includes the institutions, the relationships, the attitudes and values that govern interactions among people and contribute to economic and social development “ . ( See Grootaert, C. and van Bastelaer, T., 2002, Social capital from definition to measurement, in Grootaert, C. and van Bastelaer, T. (Eds.): Understanding and Measuring Social Capital. A Multidisciplinary Tool for Practitioners, The World Bank, Washington DC. and for measurement issues Santini I., 2008, Social capital and its impact on the production process, Int. J. Management and Decision Making, Vol. 9, n.5.) The model will be applied to the 2006 Survey on Household Income and Wealth (SHIW) of the Bank of Italy. The same model will be applied to previous Surveys on Household Income and Wealth (SHIW) of the Bank of Italy in order to highlight possible changes in the determinants of subjective well-being

Your Best Shot at Surviving the Flu Season

Millions of individuals become ill from the influenza virus every year. As an existing public health issue, it is important for patients to understand that the best way to combat the influenza virus is through prevention. This article explores key aspects of the influenza vaccine and highlights its importance in the healthcare community

EoR Foregrounds: the Faint Extragalactic Radio Sky

A wealth of new data from upgraded and new radio interferometers are rapidly improving and transforming our understanding of the faint extra-galactic radio sky. Indeed the mounting statistics at sub-mJy and uJy flux levels is finally allowing us to get stringent observational constraints on the faint radio population and on the modeling of its the various components. In this paper I will provide a brief overview of the latest results in areas that are potentially important for an accurate treatment of extra-galactic foregrounds in experiments designed to probe the Epoch of Reionization.Comment: 8 pages, 2 figures. Invited review at IAU Symposium No. 333 "Peering towards Cosmic Dawn". This submission includes updated figures wrt the version published in the proceedings volume (where an error in the plotting routine produced wrong labels for the y- and x-axis

Colorectal Cancer Screening Quality Improvement: A FITKit Mailing Initiative

According to the American Cancer Society, colorectal cancers are diagnosed in 1 in 22 men and 1 in 24 women in their lifetime. Despite the wide range of effective CRC screening options available in the US, the Hudson Headwaters Health Network (HHHN) has seen little improvement in its CRC screening rates of approximately 60-63% in recent years. This places HHHN, an FQHC in Upstate New York, well below the National Colorectal Cancer Round Table 2018 goal of 80% screening in eligible, average-risk adults. This quality improvement project sought to improve HHHN’s CRC screening rates through a new FITKit direct-mailing initiative. A literature search was conducted, informing the design of a pilot mailing initiative based on recent studies of direct-mailing FITKit outreach in comparable FQHC’s and safety net institutions. In mid-January, 2019, FITKits with return address labels and postage were mailed to 362 HHHN patients’ homes. The cohort represented a population that was age 50-75, currently failing the CRC screening measure, had not seen a PCP in the last calendar year, had BMI ≥ 30, and had 0-5 comorbidities per a network-wide EMR data search in December, 2018. These mailings were preceded by an introductory email and included a second introductory letter along with the network’s usual ‘FITKit Facts and FAQ’s’ sheet. Mailings were followed by two or more automated phone reminders to complete the screening. Only one month after mailings were released, the network received 26 completed FITKits for processing, representing a 7.14% early return rate for the initiative.https://scholarworks.uvm.edu/fmclerk/1505/thumbnail.jp

Measurement of Collins asymmetries in inclusive production of pion pairs at BABAR

Transversity Distribution, which describes the quark transverse polarization inside a transversely polarized nucleon, is the last leading-twist missing piece of the QCD description of the partonic structure of the nucleon. Transversity can be extracted from Semi-Inclusive Deep Inelastic Scattering (SIDIS) data, where, due to its chiralodd nature, it couples to a new, unknown fragmentation function, called Collins function. Independent information on the Collins function can be obtained in e+e- -> qq annihilation processes, where q = u, d, s. In the cross section formula, the Collins effect introduces a term that depends on the polarization of the quark q (antiquark q), which produces an asymmetry in the azimuthal distribution of the fragmenting products. For unpolarized beams we do not know the spin of the quarks arising from the e+e- annihilation process, and hence we cannot measure the spin effects due to the Collins function analyzing the hadron distributions generated in only one jet, which come from the fragmentation of a single quark. The Collins spin effect can instead be studied in inclusive production of two hadrons detected in opposite jets, produced by the fragmentation of a correlated qq pair: e+e- -> qq -> h1h2X. This correlation results in an observable azimuthal asymmetry distribution of the two hadrons. In this thesis, we present the measurement of the Collins asymmetries in the pions system (h1; h2 = π), using a sample of about 468 fb^(-1) of data collected at a center of mass energy of 10.54 and 10.58 GeV, with the BABAR detector at the e+e- collider PEPII at the SLAC National Accelerator Laboratory of Stanford. The Collins asymmetries are calculated in two different frames called thrust reference frame (RF12), and second hadron momentum frame (RF0), and the final results are shown as a function of the fractional energy and, for the first time in e+e- annihilation, as a function of the transverse momenta of the two pions. These results can be used in combination with Belle, HERMES, and COMPASS data in order to improve the extraction of the Transversity function, and Collins fragmentation function
