    From Alma-Ata to the Global Fund: the history of international health policy

    'Verticalization' of health care delivery, in one form or another, is the common theme pervading the history of international health policy over the last sixty years. It is often accompanied by radical policies of privatization of health services, everywhere resulting in people being forced to pay for all services. The failure of the vertical approach, of which the global public-private partnership initiatives are a modernized version, has been well recognized and its reasons are clear: actions on the distal determinants of disease (income, education, housing, the environment and infrastructure, etc) are overlooked; distribution of services dedicated to specific diseases and interventions (such as AIDS, malaria, tuberculosis, etc.) are artificially and temporarily reinforced, creating absurd and harmful forms of competition between services and making even more precarious and inefficient the work of already fragile basic health systems. This article describes the role played in this disturbing historical development by the prevailing economic ideology and its operational arm, the World Bank, with the view to reclaim international policy making processes and actors that really respond to people's health needs

    The Environmental, Economic and Social Impact of Industry 4.0 in the Food Sector: a Descriptive Literature Review

    Get PDF
    Industries today are facing new technological changes. Thanks to the introduction of new tools and technologies of the so-called Industry 4.0, industrial processes are becoming more automated and interconnected. In the meantime, laws and international meetings, such as the 2030 Agenda, ask companies to be more sustainable. Considering these premises, this study aims to analyse the available studies that focus on a possible link between these two topics, investigating the sustainability of 4.0 innovations in the food sector. The work carried out a literature analysis on the Scopus scientific database, looking for papers published in English all over the world. Results highlight that among the three pillars of sustainability, the environmental is the most studied one. More efforts should be done, instead, from an economic and social point of view. However, even if the available studies are still few, they are increasing over the last few years, also spreading geographically, underling the importance of these topics in the near future

    Oscillations above the barrier in the fusion of 28Si + 28Si

    Get PDF
    Fusion cross sections of 28Si + 28Si have been measured in a range above the barrier with a very small energy step (DeltaElab = 0.5 MeV). Regular oscillations have been observed, best evidenced in the first derivative of the energy-weighted excitation function. For the first time, quite different behaviors (the appearance of oscillations and the trend of sub-barrier cross sections) have been reproduced within the same theoretical frame, i.e., the coupled-channel model using the shallow M3Y+repulsion potential. The calculations suggest that channel couplings play an important role in the appearance of the oscillations, and that the simple relation between a peak in the derivative of the energy-weighted cross section and the height of a centrifugal barrier is lost, and so is the interpretation of the second derivative of the excitation function as a barrier distribution for this system, at energies above the Coulomb barrier.Comment: submitted to Physics Letters

    Time stability of asymmetric Fabry-Perot modulator based analog lightwave links

    Get PDF
    Lightwave links for analog signal transfer are being developed and evaluated for application in high-density interconnects. The reflective links are based on compact electro-optic intensity modulators connected by ribbons of single-mode fibres to remotely located transceivers (lasers and photoreceivers) and read-out electronics. For long-term characterization, four Asymmetric Fabry-Perot Modulator (AFPM) prototypes were continuously operated and monitored over a period of eight monthes. The collected data allow evaluation of the system time stability and simulation of the possible recalibration procedures. The recalibration requirements to achieve the desirable accuracy and reliability are inferred statistically

    Higher in-hospital mortality during weekend admission for acute coronary syndrome: a large-scale cross-sectional Italian study

    Get PDF
    AIMS: An increased mortality risk during weekend hospital admission has been consistently observed. In the present study, we evaluated whether the current improvement in management of acute coronary syndromes (ACS) has reduced this phenomenon. METHODS AND RESULTS: We extracted data from the Italian National Healthcare System Databank of 80\u200a391 ACS admissions in the region of Lombardia between 2010 and 2014. ICD-9 codes were used to assess the diagnosis. We performed a multiple logistic regression analysis to compare the mortality rates between weekend and weekday admissions.Mean age of the study population was 67.6 years; 30.1% of patients were women. ST segment elevation myocardial infarction (STEMI) accounts for 42.2% of admissions. The total in-hospital mortality was 3.05% and was positively predicted by weekend admission [odds ratio (OR) 1.13, P\u200a=\u200a0.006], age and female sex. The weekend effect on mortality was only significant for STEMI (OR 1.11, P\u200a=\u200a0.04) in comparison to non-STEMI (NSTEMI) or unstable angina.The trend of the risk of death was found to be negatively correlated with age: the risk of death was significantly higher in all age clusters younger than 75 (OR 1.22, P\u200a<\u200a0.01) and even greater in the very young subgroup under 45 years of age (OR 2.09, P\u200a=\u200a0.03). CONCLUSION: Our data indicate that increased mortality risk is still present during weekend admissions. This phenomenon is particularly evident in younger patients and in individuals admitted for STEMI

    Two trials were conducted to evaluate the effect of moderate (0.7 kg) and accelerated (0.9 kg) average daily gain before (trial 1) and after (trial 2) puberty on body condition, metabolic profile, and first lactation milk production of Italian Holstein-Friesian heifers. There were 20 heifers in trial 1 and 22 in trial 2. Trials started when heifers averaged 150 and 300 kg of body weight in trial 1 and 2, respectively, and lasted 7 mo (experimental period). Across diet groups, half of the heifers were mated at first estrus after 370 kg and the other half after 420 kg of body weight gain. Actual average daily gains were 0.667 and 0.775 kg in trial 1 and 0.748 and 0.824 kg in trial 2 for moderate and accelerated experimental groups, respectively. Diets for high average daily gain did not affect body condition during growing phase in trial 1, whereas it did in trial 2. High average daily gain increased plasma glucose in trial 1 and plasma urea concentration in trial 2. Rearing diet did not affect milk production and milk protein percent; age in both trials. High average daily gain decreased milk fat percentage in trial 2. Early calving negatively influenced milk production in both trials and milk fat percentage in trial 1. Early calving heifers showed higher protein percentage than those with late calving only in trial 1

    Space and Time pattern of mid-velocity IMF emission in peripheral heavy-ion collisions at Fermi energies

    Full text link
    The emission pattern in the V_perp - V_par plane of Intermediate Mass Fragments with Z=3-7 (IMF) has been studied in the collision 116Sn + 93Nb at 29.5 AMeV as a function of the Total Kinetic Energy Loss of the reaction. This pattern shows that for peripheral reactions most of IMF's are emitted at mid-velocity. Coulomb trajectory calculations demonstrate that these IMF's are produced in the early stages of the reaction and shed light on geometrical details of these emissions, suggesting that the IMF's originate both from the neck and the surface of the interacting nuclei.Comment: 4 pages, 3 figures, RevTex 3.1, submitted to Phys.

    Energy and angular momentum sharing in dissipative collisions

    Full text link
    Primary and secondary masses of heavy reaction products have been deduced from kinematics and E-ToF measurements, respectively, for the direct and reverse collisions of 93Nb and 116Sn at 25 AMeV. Light charged particles have also been measured in coincidence with the heavy fragments. Direct experimental evidence of the correlation of energy-sharing with net mass transfer has been found using the information from both the heavy fragments and the light charged particles. The ratio of Hydrogen and Helium multiplicities points to a further correlation of angular momentum sharing with net mass transfer.Comment: 21 pages, 20 figures. Submitted to European Physics Journal
