Significant Red: Watercolour and the Uses of Red Pigments in Military and Architectural Conventions
Authors: Miyamoto Bénédicte
Published: January 2019

L’utilisation de la couleur rouge en aquarelle s’est révélée particulièrement déconcertante pour les artistes des xviie et xviiie siècles. L’éventail des prix était large, et longue était la liste des différentes appellations et des nuances respectives de pigments produisant le rouge. Du choix du peintre, qu’il se soit agi d’une stratégie économique ou d’une décision esthétique, dépendait également l’endurance du produit fini. Pourtant, bien que cause d’incertitudes significatives, la couleur rouge n’en était pas moins une couleur de prime importance. Non seulement l’époque moderne scella-t-elle son statut de couleur primaire, mais la couleur rouge avait déjà acquis de longue date une signification prépondérante, au cœur de l’industrie du livre tout d’abord, et dans les représentations architecturales et militaires conventionnelles ensuite. Cet article examine ce que signifiait le rouge dans tous ses pigments, comment la codification à l’époque moderne en apprivoisa l’emploi, et pourquoi les emplois conventionnels du rouge, se diffusant à l’échelle européenne, entravèrent une pratique plus inventive de l’aquarelle.
« What Dangerous Men » : La pratique de la médecine sur l’île de la Dominique à la fin du xviiie siècle
Authors: Cournil Mélanie
Published: January 2019

Au cours du xviiie siècle, le développement du système esclavagiste dans les Antilles britanniques attira de nombreux colons désireux de mener une carrière transatlantique. Clercs, intendants, comptables et autres professionnels vinrent ainsi grossir les rangs de ceux qui s’enrichissaient grâce au labeur des esclaves africains. Parmi ceux-ci, les médecins occupaient une place particulière car les soins qu’ils apportaient aux esclaves visaient à atténuer les effets destructeurs et débilitants du système plantaire. Cet article se concentre sur trois médecins écossais, collègues, travaillant sur l’île de la Dominique dans les années 1790. En s’appuyant notamment sur le journal intime de l’un d’entre eux, cette étude a pour ambition de confronter les différences dans leur pratique médicale et d’interroger l’influence du système esclavagiste sur leur approche scientifique et leurs motivations personnelles. Ce faisant, il dresse un portrait de la violence du quotidien de cette société coloniale.
Men, Women, and Not Quite Non-Persons: Derivatization in Roxana
Authors: Barr Rebecca Anne
Published: January 2019

This article argues that Roxana exemplifies a peculiarly modern mode of “derivatization”: a form of “ontological reductionism” articulated by Ann J. Cahill in which individuals are diminished to “the reflection, projection, or expression of another being’s identity, drives, fears [...] reducible in all ways to the derivatizing subject’s existence”. The essay analyses the novel’s representation of secondary characters’ stunted subjectivities and the protagonist’s exploitation of their body, agency, and consent. Reading the sexual assault on Amy as an example of Roxana’s pleasure in overriding subjective autonomy and a violent expression of her “separated capacity”, the article shows how the novel explores the social and subjective self-harm of such instrumental approaches. The article suggests that not only does derivatization characterize all of Roxana’s relations, including those with men, but that its ethical harms are also the ultimate cause of her tragically reduced selfhood.
Contaminazione ambientale ed elaborazione del rischio sanitario: i costi dell’incertezza. Una ricerca antropologica sul “gass-ra-doon” nel quartiere “Tamburi” (Taranto)
Authors: Alliegro Enzo V.
Published: January 2019

Nel settembre 2018 l’Agenzia Regionale per la Protezione dell’Ambiente di Puglia ha rilevato nelle scuole del quartiere Tamburi (Taranto) concentrazioni molto alte di un gas cancerogeno, il radon. Con una intensa ricerca di campo e l’impiego comparativo di molteplici fonti documentarie relative ad una città industrializzata ad altissimo tasso di percezione del rischio sanitario, lo studio affronta il problema del rapporto tra i sistemi pubblici di tutela ambientale e sanitaria e le risposte attivate dalle popolazioni che vivono nell’area interessata. Con l’analisi di aspetti contestuali e la disamina di dinamiche di costruzione simbolica, l’articolo inoltre si sofferma sul concetto di percezione del rischio mostrando come esso sia il prodotto di un processo di elaborazione che giunge a configurazioni sincretiche e contingenti.
Cutting Edge: Early Attrition of Memory T Cells during Inflammation and Costimulation Blockade Is Regulated Concurrently by Proapoptotic Proteins Fas and Bim

Published: January 2019

Apoptosis of CD8 T cells is an essential mechanism that maintains immune system homeostasis, prevents autoimmunity, and reduces immunopathology. CD8 T cell death also occurs early during the response to both inflammation and costimulation blockade (CoB). In this article, we studied the effects of a combined deficiency of Fas (extrinsic pathway) and Bim (intrinsic pathway) on early T cell attrition in response to lymphocytic choriomeningitis virus infection and during CoB during transplantation. Loss of Fas and Bim function in Bcl2l11−/−Faslpr/lpr mice inhibited apoptosis of T cells and prevented the early T cell attrition resulting from lymphocytic choriomeningitis virus infection. Bcl2l11−/−Faslpr/lpr mice were also resistant to prolonged allograft survival induced by CoB targeting the CD40-CD154 pathway. These results demonstrate that both extrinsic and intrinsic apoptosis pathways function concurrently to regulate T cell homeostasis during the early stages of immune responses and allograft survival during CoB.
Lupus-Associated Immune Complexes Activate Human Neutrophils in an FcγRIIA-Dependent but TLR-Independent Response
Authors: Bonegio Ramon G. , Lin Jessica D. , Beaudette-Zlatanova Britte , York Michael R. , Menn-Josephy Hanni , Yasuda Kei
Published: January 2019

Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by the presence of autoantibodies against nucleic acids and nucleoproteins. Anti-dsDNA Abs are considered a hallmark of SLE, and previous studies have indicated that nucleic acid–containing immune complexes (ICs) induce B cell and dendritic cell activation in a TLR-dependent process. How ICs containing nucleic acids affect neutrophil function has not been well investigated. In this study, we report that nucleic acid–containing ICs derived from the sera of SLE patients induce human and mouse neutrophil activation through TLR-independent mechanisms. Soluble ICs containing Sm/RNP, an RNA Ag, activate human neutrophils to produce reactive oxygen species (ROS) and IL-8. In contrast, ICs containing DNA have to be immobilized to efficiently activate neutrophils. We found that deleting TLR7 or TLR9, the receptors for RNA and DNA, had no effect on mouse neutrophil activation induced by RNA-containing and immobilized DNA–containing ICs. Binding of ICs are mediated through FcγRIIA and FcγRIIIB. However, neutrophil activation induced by RNA- and DNA-containing ICs requires FcγRIIA, as blocking FcγRIIA inhibited ROS release from neutrophils. RNA-containing ICs induce calcium flux, whereas TLR7/8 ligand R848 do not. Surprisingly, chloroquine inhibits calcium flux induced by RNA-containing ICs, suggesting that this lesser known function of chloroquine is involved in the neutrophil activation induced by ICs. These data indicate the SLE-derived ICs activate neutrophils to release ROS and chemokines in an FcγRIIA-dependent and TLR7- and TLR9-independent manner that likely contributes to local tissue inflammation and damage.

CK11 is a rainbow trout (Oncorhynchus mykiss) CC chemokine phylogenetically related to both mammalian CCL27 and CCL28 chemokines, strongly transcribed in skin and gills in homeostasis, for which an immune role had not been reported to date. In the current study, we have demonstrated that CK11 is not chemotactic for unstimulated leukocyte populations from central immune organs or mucosal tissues but instead exerts a potent antimicrobial activity against a wide range of rainbow trout pathogens. Our results show that CK11 strongly inhibits the growth of different rainbow trout Gram-positive and Gram-negative bacteria, namely Lactococcus garvieae, Aeromonas salmonicida subsp. salmonicida, and Yersinia ruckeri and a parasitic ciliate Ichthyophthirius multifiliis. Similarly to mammalian chemokines and antimicrobial peptides, CK11 exerted its antimicrobial activity, rapidly inducing membrane permeability in the target pathogens. Further transcriptional studies confirmed the regulation of CK11 transcription in response to exposure to some of these pathogens in specific conditions. Altogether, our studies related to phylogenetic relations, tissue distribution, and biological activity point to CK11 as a potential common ancestor of mammalian CCL27 and CCL28. To our knowledge, this study constitutes the first report of a fish chemokine with antimicrobial activity, thus establishing a novel role for teleost chemokines in antimicrobial immunity that supports an evolutionary relationship between chemokines and antimicrobial peptides.
Filamentous bacteriophage
Authors: Garg Pankaj
Published: January 2019

A new modality of targeting therapeutic drugs based on the use of bacteriophage (virus), as an emerging tool for specific targeting and for vaccine development, has been an area of interest for genetic and cancer research. The approach is based on genetic manipulation and modification in the chemical structure of a filamentous bacteriophage that facilitates its application not only for in vivo imaging but also for therapeutic purpose, as a gene delivery vehicle, as drug carriers, and also as an immunomodulatory agent. Filamentous bacteriophage on account of its high surface holding ability with adaptable genetic engineering properties can effectively be used in loading of chemical and genetic drugs specifically on to the targeted lesion location. Moreover, the specific peptides/proteins exhibited on the phage surface can be applied directly as self-navigating drug delivery nanovehicles. The present review article has been framed with an objective to summarize the importance of bacteriophage in phage cancer therapy and to understand the possible future prospective of this approach in developing new tools for biotechnological and genetic research, especially in phage -mediated cancer therapy. Importantly, the peptides or proteins emerging from the surface of a nano carrier will make the expense of such peptides economically more effective as compared to other immunological tools, and this seems to be a potential approach for developing a new nanodrug carrier platform.
Computability Theory
Authors: Brattka Vasco , Downey Rodney G. , Knight Julia F. , Lempp Steffen
Published: January 2019

Computability and computable enumerability are two of the fundamental notions of mathematics. Interest in effectiveness is already apparent in the famous Hilbert problems, in particular the second and tenth, and in early 20th century work of Dehn, initiating the study of word problems in group theory. The last decade has seen both completely new subareas develop as well as remarkable growth in two-way interactions between classical computability theory and areas of applications. There is also a great deal of work on algorithmic randomness, reverse mathematics, computable analysis, and in computable structure theory/computable model theory.

The goal of this workshop is to bring together researchers representing different aspects of computability theory to discuss recent advances, and to stimulate future work.
Mini-Workshop: Entropy, Information and Control
Authors: Colonius Fritz , Downarowicz Tomasz , Kawan Christoph , Nair Girish
Published: January 2019

This mini-workshop was motivated by the emerging field of networked control, which combines concepts from the disciplines of control theory, information theory and dynamical systems. Many current approaches to networked control simplify one or more of these three aspects, for instance by assuming no dynamical disturbances, or noiseless communication channels, or linear dynamics. The aim of this meeting was to approach a common understanding of the relevant results and techniques from each discipline in order to study the major, multi-disciplinary problems in networked control.
Statistical Inference for Structured High-dimensional Models
Authors: Juditsky Anatoli , Tsybakov Alexandre B. , Zhang Cun-Hui
Published: January 2019

High-dimensional statistical inference is a newly emerged direction of statistical science in the 21 century. Its importance is due to the increasing dimensionality and complexity of models needed to process and understand the modern real world data. The main idea making possible meaningful inference about such models is to assume suitable lower dimensional underlying structure or low-dimensional approximations, for which the error can be reasonably controlled. Several types of such structures have been recently introduced including sparse high-dimensional regression, sparse and/or low rank matrix models, matrix completion models, dictionary learning, network models (stochastic block model, mixed membership models) and more. The workshop focused on recent developments in structured sequence and regression models, matrix and tensor estimation, robustness, statistical learning in complex settings, network data, and topic models.
Applied Harmonic Analysis and Data Processing
Authors: Daubechies Ingrid , Kutyniok Gitta , Rauhut Holger , Strohmer Thomas
Published: January 2019

Massive data sets have their own architecture. Each data source has an inherent structure, which we should attempt to detect in order to utilize it for applications, such as denoising, clustering, anomaly detection, knowledge extraction, or classification. Harmonic analysis revolves around creating new structures for decomposition, rearrangement and reconstruction of operators and functions—in other words inventing and exploring new architectures for information and inference. Two previous very successful workshops on applied harmonic analysis and sparse approximation have taken place in 2012 and in 2015. This workshop was the an evolution and continuation of these workshops and intended to bring together world leading experts in applied harmonic analysis, data analysis, optimization, statistics, and machine learning to report on recent developments, and to foster new developments and collaborations.

Published: January 2019

This workshop continued to foster the collaboration between researchers working in analysis and probability, respectively. Some core areas, in which this happens with high success, belong to the objectives of this meeting: stochastic homogenization of various quantities in random media and random operators, metastability in several particle models with stochastic input that are triggered by physics reasonings, emergence of macroscopic effects in large random structures like graphs or permutations. A main feature present was the exploration of the benefit of a high-level combination of methods from both fields: analysis and probability.

Insignia of power
Authors: Frie Adrienne C.
Published: January 2019

Bird symbolism in the Dolenjska Hallstatt culture had strong associations with ritual and hierarchy, as demonstrated by bird imagery on insignia of power such as bronze vessels, wagons, and sceptres. The elaboration of such items with birds may have elevated items of prestige to items of ritual potency, highlighting the sacred and worldly power of the elite males with whom these items were associated. Avian depictions on bronze vessels, sceptres, and wagons with important cosmological and ritual associations indicate that birds were deeply entangled in presentations of status, particularly those that blurred the lines between the secular and sacred realms.

Investigating the accounting systems and their progressive development during the prehistoric period is a critical issue in recognition of human societies, their communication, and formation of inter- and intra-regional trade system transformed to innovation of writing systems. The present study aims at studying the typology and classification of the Chalcolithic (Middle Bakun, 4500 BC) period. Numerical objects discovered in Tal-e Mash Karim in Semirom district located in Esfahan province, Iran. The discovered cultural materials contain 32 numerical tokens and a clay tallying slab. The numerical tokens are divided into three main categories and seven subcategories. On that basis, round and oval shape tokens for measuring agricultural products and flat and disc shape tokens are representing animals and animal products related productions. The discovery of a tallying slab beside the artifacts all is proving the existence on an early accounting system.

Polskie początki Wydziału Nauk Matematycznych i Przyrodniczych Uniwersytetu we Fryburgu i polski wkład we fryburską rewolucję przemysłową
Authors: Kocurek Wojciech
Published: January 2019

The article is dedicated to high-tech companies founded by Poles at the end of the 19th century in the rural canton of Fribourg in Switzerland. The text is divided into two parts. In the first part, the author attempts to present the economic, social and political reality of Fribourg in a period of intense industrialization in the world and the formation of the liberal free market system. In this rapidly changing reality, the new Catholic-conservative authorities of the canton tried to lead to establishing of a comprehensive, but also different system of a “Christian republic”, whose aim was to achieve social justice consistent with the teachings of the Gospel. In order to complete the project, the cantonal government did not shy away from using the possibilities and measures offered by the contemporary world. Decision-makers, led by Georges Python, needed support from the society, who was aware of the changes. Due to this fact, it became necessary to establish a university capable of shaping new attitudes and views. However, the costs significantly exceeded the financial capabilities of the agricultural and relatively poor canton of Fribourg. In these less favourable circumstances, a conscious policy of industrialization was the way out of the deadlock. Newly created industrial institutions were to contribute to an increase of cash inflows to the canton and thus allow for the financing of the university, which would also become an intellectual foundation for the emerging industry. The activity of Polish scientists, which is the subject of the second part of the article, matched this philosophy perfectly. The Poles invited to cooperate with Python, i.e. Józef Wierusz-Kowalski, Ignacy Mościcki and Jan Modzelewski, created the foundations of the Faculty of Mathematical and Natural Sciences at the University of Fribourg. As members of the faculty, in addition to teaching, they conducted research into, among other things, nitric acid synthesis and construction of electrical capacitors. Convinced of the need to put their innovations into wide production, they financed and built the first experimental factories and, over time, led to the development of a nitric acid factory and a high-voltage capacitor factory on an industrial scale. Although after the First World War the commitment of the Poles stopped, the 30 years of academic research and experience clearly showed that a conscious cooperation of policy-makers and highly qualified scientific personnel can bring surprising and unexpected results.

Contemporary follow-up imaging after endovascular repair of lower extremity atherosclerotic lesions
Authors: Michalska Marta , Kazimierczak Wojciech , Leszczyński Waldemar , Nadolska Katarzyna , Bryl Łukasz
Published: January 2019

Atherosclerotic disease is currently one of the most important problems of modern medicine because it is a leading cause of increased morbidity, morbidity and mortality, and disability in the Western World. Atherosclerosis of the lower limbs (peripheral arterial disease – PAD) significantly affects the quality of life and in a considerable proportion of patients is a cause of disability. Radical treatment of PAD, both surgical and endovascular, aims at revascularisation of ischaemic tissues distal to obstructed arteries. Surveillance imaging is an important part of patient management after endovascular repair of PAD. Apart from availability and contraindications, challenges of imaging include calcifications, flow dynamics, and stent-related artefacts. The aim of this paper was to review the current literature on imaging methods for follow-up after endovascular repair of atherosclerotic lesions, with special attention paid to novel techniques. As a non-invasive modality, ultrasound is still the first-line examination, but computed tomography angiography remains a current state-of-the art technique for follow-up. However, since current imaging recommendations seem not to adhere to contemporary imaging possibilities, more attention should be paid to recent improvements in magnetic resonance angiography technology.

Abstract. Aerosol particles are of importance in the Earth's radiation budget since
they scatter and absorb sunlight. While extensive studies of aerosol optical
properties have been conducted at ground sites, vertical measurements and
characterization are very limited in megacities. In this work, we present
simultaneous real-time online measurements of aerosol optical properties at
ground level and at 260 m on a meteorological tower from 16 November to
13 December in 2016 in Beijing along with measurements of continuous vertical
profiles during two haze episodes. The average (±1σ) scattering
and absorption coefficients (bsca and babs; λ=630 nm) were 337.6 (±356.0) and 36.6 (±33.9) Mm−1 at
260 m, which were 26.5 % and 22.5 % lower than those at ground
level. Single scattering albedo (SSA), however, was comparable between the
two heights, with slightly higher values at ground level (0.89±0.04).
Although bsca and babs showed overall similar
temporal variations between ground level and 260 m, the ratios of 260 m to ground
varied substantially from less than 0.4 during the clean stages of haze
episodes to > 0.8 in the late afternoon. A more detailed
analysis indicates that vertical profiles of bsca,
babs, and SSA in the low atmosphere were closely related to the
changes in meteorological conditions and mixing layer height. The mass
absorption cross section (MAC) of equivalent black carbon (eBC, λ=630 nm) varied substantially from 9.5 to 13.2 m2 g−1
in winter in Beijing, and it was strongly associated with the mass ratio of
coating materials on refractory BC (rBC) to rBC (MR), and also the
oxidation degree of organics in rBC-containing particles. Our results show
that the increases in MAC of eBC in winter were mainly caused by
photochemically produced secondary materials. Light absorption of organic
carbon (brown carbon, BrC) was also important in winter, which on average
accounted for 46 (±8.5) % and 48 (±9.3) % of the total
absorption at 370 nm at ground level and 260 m, respectively. A linear
regression model combined with positive matrix factorization analysis was
used to show that coal combustion was the dominant source contribution of BrC
(48 %–55 %) followed by biomass burning (17 %) and
photochemically processed secondary organic aerosol (∼20 %) in
winter in Beijing.
Iodine speciation and size distribution in ambient aerosols at a coastal new particle formation hotspot of China
Authors: Yu Huan , Ren Lili , Huang Xiangpeng , Xie Mingjie , He Jun , Xiao Hang
Published: January 2019

Abstract. Intense new particle formation (NPF) events were observed in the coastal atmosphere during algae growth and farming season at Xiangshan Gulf of east China coast. High nucleation-mode iodine concentrations measured by ultra-performance liquid chromatography coupled with quadruple time-of-flight mass spectrometry (UPLC/Q-TOF-MS) confirmed that the NPF events were induced by iodine species. Farmed microalgae, as well as wild algae, could be an important NPF source in coastal areas of China. For the first time, we identified 5 inorganic iodine species, 45 organic iodine compounds (35 molecular formulas) and a group of iodide-organic adducts in ambient aerosols. The concentrations and size distributions of iodine species down to 10 nanometers were measured during the iodine-induced NPF, continental NPF and non-NPF days at the coastal site and compared to those at an inland site. The iodine in the above four types of aerosol samples were characterized by iodate, aromatic iodine compounds, iodoacetic acid/iodopropenoic acid and iodide-organic adducts, respectively. This study sheds light on the iodine sources, formation mechanism and its contribution to the coastal NPF in the context of heavy air pollution in eastern China.
Froth Production in Potable Water without Chemicals
Authors: Hassan Ghanim , Edyvean Robert G. J.
Published: January 2019

Abstract. Froth flotation is a well-known solid-liquid separation technique. Hydrophobicity is the main driving force for such processes. Hydrophobic solids attach to air bubbles and rise up while hydrophilic or less hydrophobic species settle down. Froth can be produced with chemical frothers such as alcohols and polyglycols. However, the use of chemicals limits the use of this separation method in applications such as drinking water, food, and pharmaceutical industries. Therefore, developing a technique that produces froth without adding any chemicals would be useful to such industries. This work demonstrates that with suitable operating parameters a 27 cm froth height can be obtained in a 20 cm diameter column by using an air flow rate of 130 l/min.
A stochastic event-based approach for flood estimation in catchments with mixed rainfall and snowmelt flood regimes
Authors: Filipova Valeriya , Lawrence Deborah , Skaugen Thomas
Published: January 2019

Abstract. The estimation of extreme floods is associated with high uncertainty, in part
due to the limited length of streamflow records. Traditionally, statistical
flood frequency analysis and an event-based model (PQRUT) using a single
design storm have been applied in Norway. We here propose a stochastic PQRUT
model, as an extension of the standard application of the event-based PQRUT
model, by considering different combinations of initial conditions, rainfall
and snowmelt, from which a distribution of flood peaks can be constructed.
The stochastic PQRUT was applied for 20 small- and medium-sized catchments in
Norway and the results give good fits to observed peak-over-threshold (POT) series.
A sensitivity analysis of the method indicates (a) that the soil saturation level
is less important than the rainfall input and the parameters of the PQRUT
model for flood peaks with return periods higher than 100 years and (b) that
excluding the snow routine can change the seasonality of the flood peaks.
Estimates for the 100- and 1000-year return level based on the stochastic
PQRUT model are compared with results for (a) statistical frequency analysis
and (b) a standard implementation of the event-based PQRUT method. The
differences in flood estimates between the stochastic PQRUT and the
statistical flood frequency analysis are within 50 % in most catchments.
However, the differences between the stochastic PQRUT and the standard
implementation of the PQRUT model are much higher, especially in catchments
with a snowmelt flood regime.
Exploring PubMed as a reliable resource for scholarly communications services
Authors: Ossom Williamson Peace , Minter Christian I. J.
Published: January 2019

Objective: PubMed’s provision of MEDLINE and other National Library of Medicine (NLM) resources has made it one of the most widely accessible biomedical resources globally. The growth of PubMed Central (PMC) and public access mandates have affected PubMed’s composition. The authors tested recent claims that content in PMC is of low quality and affects PubMed’s reliability, while exploring PubMed’s role in the current scholarly communications landscape.Methods: The percentage of MEDLINE-indexed records was assessed in PubMed and various subsets of records from PMC. Data were retrieved via the National Center for Biotechnology Information (NCBI) interface, and follow-up interviews with a PMC external reviewer and staff at NLM were conducted.Results: Almost all PubMed content (91%) is indexed in MEDLINE; however, since the launch of PMC, the percentage of PubMed records indexed in MEDLINE has slowly decreased. This trend is the result of an increase in PMC content from journals that are not indexed in MEDLINE and not a result of author manuscripts submitted to PMC in compliance with public access policies. Author manuscripts in PMC continue to be published in MEDLINE-indexed journals at a high rate (85%). The interviewees clarified the difference between the sources, with MEDLINE serving as a highly selective index of journals in biomedical literature and PMC serving as an open archive of quality biomedical and life sciences literature and a repository of funded research.Conclusion: The differing scopes of PMC and MEDLINE will likely continue to affect their overlap; however, quality control exists in the maintenance and facilitation of both resources, and funding from major grantors is a major component of quality assurance in PMC. This article has been approved for the Medical Library Association’s Independent Reading Program.
Almost half of references in reports on new and emerging nondrug health technologies are grey literature
Authors: Farrah Kelly , Mierzwinski-Urban Monika
Published: January 2019

Objective: The research investigated how frequently grey literature is used in reports on new and emerging nondrug health technologies, which sources are most cited, and how grey literature searching is reported.Methods: A retrospective review of references cited in horizon scanning reports on nondrug health technologies—including medical devices, laboratory tests, and procedures—was conducted. A quasi-random sample of up to three reports per agency was selected from a compilation of reports published in 2014 by international horizon scanning services and health organizations.Results: Twenty-two reports from 8 agencies were included in the analysis. On average, 47% (288/617) of references listed in the bibliographies of the horizon scanning reports were grey literature. The most frequently cited type of grey literature was information from manufacturers (30% of all grey literature references), regulatory agencies (10%), clinical trial registries (9%), and other horizon scans or evidence synthesis reports (9%). The US Food and Drug Administration (FDA) and ClincalTrials.gov were the most frequently cited specific sources, constituting 7% and 8% of grey literature references, respectively. Over two-thirds (15/22) of the analyzed reports provided some details on search methodology; all 15 of these reported searching some grey literature.Conclusions: In this sample, grey literature represented almost half of the references cited in reports on new and emerging nondrug health technologies. Of these grey literature references, almost half came from three sources: the manufacturers, ClinicalTrials.gov, and the FDA. There was wide variation in the other sources cited. Literature search methodology was often insufficiently reported for analysis.
Evaluation of drug information resources for drug-ethanol and drug-tobacco interactions
Authors: Beckett Robert D. , Stump Curtis D. , Dyer Megan A.
Published: January 2019

Objective: The research evaluated point-of-care drug interaction resources for scope, completeness, and consistency in drug-ethanol and drug-tobacco content.Methods: In a cross-sectional analysis, 2 independent reviewers extracted data for 108 clinically relevant interactions using 7 drug information resources (Clinical Pharmacology Drug Interaction Report, Facts & Comparisons eAnswers, Lexicomp Interactions, Micromedex Drug Interactions, Drug Interactions Analysis and Management, Drug Interaction Facts, and Stockley’s Drug Interactions). Scope (presence of an entry), completeness (content describing mechanism, clinical effects, severity, level of certainty, and course of action for each present interaction; up to 1 point per assessed item for a total possible score of 5 points), and consistency (similarity among resources) were evaluated.Results: Fifty-three drug-ethanol and 55 drug-tobacco interactions were analyzed. Drug-ethanol interaction entries were most commonly present in Lexicomp (84.9%), Clinical Pharmacology (83.0%), and Stockley’s Drug Interactions (73.6%), compared to other resources (p<0.05). Drug-tobacco interactions were more often covered in Micromedex (56.4%), Stockley’s Drug Interactions (56.4%), Drug Interaction Facts (43.6%), and Clinical Pharmacology (41.8%) (p<0.001). Overall completeness scores were higher for Lexicomp, Micromedex, Drug Interaction Facts, and Facts & Comparisons (median 5/5 points, interquartile range [IQR] 5 to 5, p<0.001) for drug-ethanol and for Micromedex (median 5/5 points, IQR 5 to 5, p<0.05) for drug-tobacco, compared to other resources. Drug Interaction Facts and Micromedex were among the highest scoring resources for both drug-ethanol (73.7%, 68.6%) and drug-tobacco (75.0%, 32.3%) consistency.Conclusions: Scope and completeness were high for drug-ethanol interactions, but low for drug-tobacco interactions. Consistency was highly variable across both interaction types.

Trajetórias das juventudes populares – vidas mambembes que se resignificam em seus cotidianos
Authors: Rodrigues Pereira Rego Noelia
Published: January 2019

As análises deste estudo antropológico revelam, em diálogo constante com outras pesquisas relacionadas ao trabalho e à educação, as incertezas da sociedade atual, as formas diluídas das organizações produtivas de atividade humana no âmbito de uma sociedade regida pelo capital, dentre outros elementos que subjazem ao que podemos chamar de trajetórias mambembes de possibilidades, acesso e ascensão. Em nosso caso, das juventudes populares estudantes de EJA – Educação de Jovens e Adultos, com trabalhos precarizados. Ressalta-se ainda a importância do associativismo dessas juventudes, por meio de coletivos e movimentos sociais como forma de resistência e de sobrevivência social e, principalmente, física, no bojo de uma sociedade marcada pelas mais intensas e perversas desigualdades.
Violência, juventudes e educação: uma leitura sobre construções discursivas
Authors: Carranza  Weihmuller Valentina , Helena Ferraz de Siqueira Vera , Costa da Silva Andréa
Published: January 2019

O artigo lança mão do enquadramento de vertentes sócio antropológicas e pós estruturalistas para discutir/tensionar a noção de violência, evidenciando-a como narrativa, instituidora de “regimes de verdades”. Aborda, nessa mesma perspectiva, as estatísticas produzidas pelo Estado e faz uma análise de “textos” no campo da educação em saúde, caracterizando-os como estratégias discursivas de saber-poder, monopolizadas pelos aparelhos midiáticos, que funcionam como norteadores dos campos de ação e das prioridades das políticas públicas, ao mesmo tempo que exercem um domínio sobre as formas através das quais os próprios agentes sociais (entre eles os próprios jovens) se colocam em relação a seus problemas e possibilidades de superá-los.

Published: January 2019

Esta pesquisa teve por objetivo investigar qual a perspectiva dos agentes pedagógicos sobre as práticas de lazer de adolescentes em cumprimento de medida socioeducativa na cidade de Campinas – SP. Para tal, baseou-se na análise de documentos relacionados ao Sistema Nacional de Atendimento Socioeducativo e na realização de entrevistas semiestruturadas com agentes pedagógicos envolvidos nesse âmbito. Os dados foram relacionados entre si com a finalidade de se apreender como a legislação e o campo prático interagem e se influenciam. Foi possível identificar a existência de práticas de lazer no contexto das medidas socioeducativas e concepções de lazer voltadas à prática da liberdade. Todavia averiguou-se que essas práticas são permeadas por concepções funcionalistas de lazer.

Przygotowanie uczniów do funkcjonowania w środowisku zróżnicowanym kulturowo
Authors: Baranowska Aneta Sylwia
Published: January 2019

Współcześnie młodzi ludzie, na skutek m.in. wzrostu ruchów migracyjnych w skali światowej, coraz częściej stykają się z osobami pochodzącymi z innych kultur. Istotne wydaje się zatem przygotowanie ich do życia w środowisku zróżnicowanym kulturowo, zwłaszcza, że zdolność funkcjonowania w wielokulturowym otoczeniu uważana jest za jedną z najważniejszych umiejętności społecznych XXI wieku. W związku z tym w szkołach powinny być realizowane działania z zakresu edukacji międzykulturowej, które uwrażliwią młodych ludzi na różnorodność kulturową oraz przyczynią się do rozwinięcia u nich postaw otwartości i szacunku do tego co odmienne.
