On insurance and health risks
Full text linkHealth risk can be defined as the likelihood of a negative health consequence occurring
due to a specific event, disease or condition. Its consequences can be strongly
detrimental to individuals and society and managing health risks is a central concern for individuals and governments
Preventing the Wernicke-Korsakoff syndrome in Australia: Cost-effectiveness of thiamin-supplementation alternatives
No full textAlcoholic Wernicke's encephalopathy has been commonplace in Australia for many years and, as this syndrome is attributed to a deficiency in the diet, it should be preventable. This study employs conventional cost-effectiveness methodology to compare the economic efficiency of several thiamin-supplementation alternatives that have been proposed for the prevention of Wernicke's encephalopathy. A series of rankings of these measures is derived from an estimated cost per case averted for each of the alternatives studied. These rankings identify the least cost-effective thiamin-supplementation alternative as that of enriching bread-making flour with thiamin
Answers in search of questions: What does the comparison of COVID19 data among Regions in Northern Italy tell us?
Full text linkSince the outbreak of the COVID-19 pandemic, discussions about the capabilities of health and social systems to control and contain infectious diseases have been reignited. In Resilient Managed Competition During Pandemics: Lessons from the Italian Experience, Costa-Font, Turatti and Levaggi ask whether or not institutional differences between the managed competition (MC) systems in three of Italy's regions may have affected their performance - and hence, population health outcomes - during the pandemic. Fuchs (2000) previously argued that institutional arrangements not only 'matter', but also sometimes 'matter a great deal' (p. 149, emphasis in original) and this may be particularly true in emergencies
Supply-side solutions targeting demand-side characteristics: causal effects of a chronic disease management program on adherence and health outcomes
Full text linkWe estimate the effects of a chronic disease management program (CDMP) which adapts various supply-side interventions to specific demand-side conditions (disease-staging) for patients with chronic kidney disease (CKD). Using a unique dataset on the entire population of the Emilia–Romagna region of Italy with hospital-diagnosed CKD, we estimate the causal effects of the CDMP on adherence indicators and health outcomes. As CKD is a progressive disease with clearly-defined disease stages and a treatment regimen that can be titrated by disease severity, we calculate dynamic, severity-specific, indicators of adherence as well as several long-term health outcomes. Our empirical work produces statistically significant and sizeable causal effects on many adherence and health outcome indicators across all CKD patients. More interestingly, we show that the CDMP produces larger effects on patients with early-stage CKD, which is at odds with some of the literature on CDMP that advocates intensifying interventions for high-cost (or late-stage) patients. Our results suggest that it may be more efficient to target early-stage patients to slow the deterioration of their health capital. The results contribute to a small, recent literature in health economics that focuses on the marginal effectiveness of CDMPs after controlling either for supply- or demand-side sources of heterogeneity
The effect of gun buy‐back law reform on homicides and suicides in Australia
Full text linkIn this paper we use the synthetic control method (SCM) to estimate the causal effects of a national legislative reform accompanied by mandatory gun buy-backs in Australia on both suicide and homicide rates. Using a rich international dataset, we are able to separate not only these two death types, but also to distinguish deaths by firearm and by other means, thereby enabling us to test substitution-of-means hypotheses. Specifically, we apply the SCM to determine whether any reductions in firearm-related death rates where wholly or partly offset by increases in the use of other means (e.g., bladed weapons, poisons) to commit suicides and perpetrate homicides. Our findings show that these gun control policies substantially reduced both homicides and suicides by firearm, but also some evidence of other-means substitution
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
