Public health transfers in kind: measuring the distributional effects in Italy
No full textThe aim of the paper is to translate into a monetary amount the benefits received by the provision of health related public services in Italy, analyze their incidence and relevance and study their implications on the distribution of income among individuals. Beyond the traditional insurance-based approach, we propose an alternative method, which assigns health related transfers according also to the individual income and self-assessed health status. We apply the two approaches to Italy in 2003. In addition, we test for equality of health opportunities among citizens

Region of Residence and Equality of Opportunity in Health: a Note on the Italian Case
Full text linkpeer reviewedThe Italian health care system is managed mainly at the regional level. For this reason health care may diff er depending on region of residence. The aim of this note is to take a rigorous ex-ante approach and test for equality of health opportunities as opposed to health outcomes, which are the ex-post results. We perform non-parametric tests to evaluate if the probability of reaching the same health status di ffers by region of residence, after controlling for other influential factors such as age, gender and income. The results underline that the geographical distribution of opportunities in health is unequal, and therefore, that regional differences in outcomes are more likely to be expected
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The optimal value range problem for the Interval (immune)Transportation Problem
Full text linkWe address the problem of finding the range of the optimal cost of a transportation problem when supply and demand vary over an interval. We consider the specific version of a transportation problem with supply inequality constraints and demand equality constraints under the assumption that the transportation costs are immune against the transportation paradox. We investigate some theoretical properties of the problem which constitute the basis of a novel solution algorithm. Our results show that the proposed algorithm hugely outperforms the best existing solution approaches
Relaxations and heuristics for the multiple non-linear separable knapsack problem
No full textWe consider the multiple non-linear knapsack problem with separable non-convex functions. The problem, which can be modeled as a (mixed) integer non-linear program, is extremely difficult to solve in practice. We present a fast heuristic algorithm, based on constructive techniques, surrogate relaxations, and local search improvements. Computational comparisons with exact and heuristic methods for general non-convex mixed integer non-linear programs show that the proposed approach provides good-quality solutions within small computing times
