Anthropometric growth pattern in ethiopian infants and children: An evaluation based on different international growth references
At the population level international growth references have been widely used as useful tools to assess a number of situations, i.e.: to predict local and general emergencies related to food and nutrition; to assess the equity of distribution of economic resources within and between communities; to evaluate the suitability of weaning practices and to screen and following at-risk groups. Nevertheless, recently several concerns were raised regarding the adequacy of currently existing growth references involving study design, population sample, time validity, and evaluation of infant and children well-being in terms of food availability and nutritional adequacy. As in the past, discussion involve also suitability of local or national reverences versus the international ones. This paper focusses on the re-evaluation of the main auxometric indexes, i.e.: height for age, weight for height and BMI in a sample of infant and children aged between 24 and 120 months from urban and rural Ethiopia. Previous evaluation based on the NCHS-1977 growth references led to striking results in terms of growth retardation while a recent evaluation based on NCHS-2000 (NHANES) growth references gave better but contradictory pictures. As consequence, concerns on the adequacy of international references use in infant and children growth assessment in the developing countries seem to be widely justified while local or national well built growth references should offer the possibility for a most realistic evaluation

Host Genetic Liability for Severe COVID-19 Associates with Alcohol Drinking Behavior and Diabetic Outcomes in Participants of European Descent
Risk factors and long-term consequences of COVID-19 infection are unclear but can be investigated with large-scale genomic data. To distinguish correlation from causation, we performed in-silico analyses of three COVID-19 outcomes (N > 1,000,000). We show genetic correlation and putative causality with depressive symptoms, metformin use (genetic causality proportion (gĉp) with severe respiratory COVID-19 = 0.576, p = 1.07 × 10−5 and hospitalized COVID-19 = 0.713, p = 0.003), and alcohol drinking status (gĉp with severe respiratory COVID-19 = 0.633, p = 7.04 × 10−5 and hospitalized COVID-19 = 0.848, p = 4.13 × 10−13). COVID-19 risk loci associated with several hematologic biomarkers. Comprehensive findings inform genetic contributions to COVID-19 epidemiology, molecular mechanisms, and risk factors and potential long-term health effects of severe response to infection
Italian burials from the Palaeolithic period. The identification of dietary habits
The identification of dietary habits is increasingly seen as a fundamental aspect for studying the ancient human populations. Accordingly, several projects aiming to identify Paleolithic individuals' dietary patterns were developed to analyze the organic component of bone tissue and identify isotopic markers to reconstruct the food typology. Bone fragments from six individuals were selected for carbon and nitrogen stable isotopes analysis. The interpretation of human isotopic data was framed through a dataset of twenty-one Italian Paleolithic individuals. The isotopic data generated for the Paleolithic individuals agree with the information already provided by the archaeological record concerning the Italian hunter and gatherer communities. Their subsistence economy was essentially grounded upon the exploitation of high protein foods, either from terrestrial fauna resources or inland lacustrine or riverine species.

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Investigation of human remains from the archaeological areas of “Parco archeologico di Ostia antica”: The role of CT imaging
Objective: Archeological excavations in the area of the “Parco archeologico di Ostia antica” uncovered human remains requiring radiological insight to clarify the etiology of multiple morphological alterations. The purpose of this paper was to analyze CT findings of the remains, to push forward the contribution of CT in anthropological analysis. Materials and methods: We examined human remains belonging to four different individuals, coming from different chronological horizons, ranging from the Roman Imperial Age (cases 1, 2 and 4) to the Middle Age (case 3). Bone remains of each individual underwent CT scan separately using a 268-slice scanner (GE, medical system, revolution CT). Results: CT findings added value in reaching effective hypotheses on the origin of bone alterations and on biological aspects of the examined individuals. In three out of four cases the radiological hypotheses corresponded to the anthropological ones (cases 1, 3 and 4), with better resolution of the inner alterations of bones which strengthened the initial hypothesis. In one case (case 2), CT imaging proposed an alternative hypothesis (i.e., osteomyelitis versus osteosarcoma). Conclusion: CT highlights internal alterations in a non-invasive manner, exposing hypotheses that are not evident or that can be underestimated from an external examination. Hence, this imaging modality may be used as a valuable tool to study archaeological remains and to detect a wide variety of pathologies, including trauma, infections, arthropathies and neoplasms, in the context of a multidisciplinary approach to archeological investigations
Archaeobotanical record from dental calculus of a Roman individual affected by bilateral temporo-mandibular joint ankylosis
Ancient dental calculus represents one of the most recent and innovative sources of archaeobotanical record. Exploring this matrix, diet, past ecology, and ethnobotanical practices of antique communities may be elucidated. In the present case-study, the tartar of an Imperial Roman man, likely a salt worker, found in the necropolis of Castel Malnome (Rome, Latium, Italy) and affected by bilateral temporo-mandibular joint ankylosis, was investigated. Despite his rare and extremely disabling affection, this male individual reached adulthood thanks to the forced removal of the anterior teeth, which allowed him to eat. Starches of Poeae and Triticeae tribe were detected, although the largest amount of the granules appeared gelatinized, suggesting that maybe the inhumate consumed well-cooked and semi-liquid stuff, due to his non-functional masticatory activity. Urticaceae and clover pollen grains documented unintentional aspiration or voluntary use of these plants as ingredients for meals and therapeutic decoctions. Indeed, since Roman times, written sources have documented nettle as an anti-inflammatory remedy to treat joint and muscle pains. Finally, the identification of secondary metabolites ascribable to the Brassicaceae family, Artemisia L., and Ephedra L. genera, paves the way for hypothesizing the consumption of these Mediterranean species with several nutritional and nutraceutical properties. All this evidence opens a picture window onto the life of this man, which should be well integrated into his community and natural environment despite the functional impairment
