Food poverty in Tuscany: local public policies and (good) practices
Authors: Berti Fabio , Valzania Andrea
Published: January 2021

Despite the reduction of hunger on an international scale, particularly in areas traditionally characterized by malnutrition, recent years have seen an increase in problems relating to food access precisely in those countries which considered themselves immune from such problems. This paper presents reflections on the theme of poverty and malnutrition based on studies conducted in Tuscany. The principal theoretical and historical aspects that characterize this phenomenon are analysed in the first section. In the second section, we discuss the instruments put in place to combat poverty and malnutrition on the national and local levels in Italy, highlighting their strong and weak points. The life-stories of 43 people subject to malnutrition and who benefit from anti-poverty measures in Tuscany are analysed in the third section. The final section is dedicated to a critical interpretation of measures set up to combat poverty in Tuscany, and of the system of production and distribution of food among the most disadvantaged social classes.
Se positionner aux côtés des personnes

Le présent article s’appuie sur une recherche menée à Mulhouse entre 2015 et 2018 sur l’insécurité alimentaire. Dans l’optique de mieux comprendre le rapport à l’alimentation des publics précaires, une soixantaine d’entretiens semi-directifs ont été conduits auprès de personnes âgées et de familles monoparentales bénéficiant d’aide alimentaire, complétés par des entretiens auprès d’acteurs des organisations de ce secteur. L’analyse des résultats montre que l’aide alimentaire délivrée, si elle apporte aux personnes des réponses concrètes, notamment matérielles, peut parfois constituer une source de souffrance. En effet, les parcours de demande d’aide ainsi que les interactions avec les acteurs de l’aide alimentaire peuvent être vécus comme un processus de désignation et d’objectivation qui tend à réduire les personnes à un rôle d’assisté. Ces processus gomment ce faisant les ressources et capacités des personnes. L’alimentation ainsi que les pratiques d’aide alimentaire peuvent au contraire se penser comme des leviers pour restaurer le lien social, elles constituent enfin un véritable enjeu de reconnaissance sociale pour ces publics.

À Montréal, les organisateurs et organisatrices communautaires (OC) interviennent dans différents champs de pratique, dont celui de la sécurité alimentaire. Ces professionnels définissent l’organisation communautaire comme une intervention de soutien professionnel et d’influence dans une communauté permettant d’agir sur les facteurs collectifs qui ont une incidence sur la santé et le bien-être. Elle s’adresse prioritairement aux populations précarisées dans une perspective de justice sociale. Cette étude porte sur les pratiques d’organisation communautaire en sécurité alimentaire. Elle s’inscrit dans une démarche de réflexivité collective entreprise dans le cadre d’une collaboration entre des chercheurs et des membres d’un Comité d’organisateur-rices communautaires en sécurité alimentaire œuvrant au sein d’un établissement du réseau de la santé et des services sociaux québécois. Cette étude a permis de dégager les rôles de l’organisation communautaire en sécurité alimentaire, de cerner les principaux défis de leur pratique et de questionner leur capacité d’action sur les inégalités sociales.
Ce que l’ignorance nous apprend
Authors: Godrie Baptiste , Bandini Aude
Published: January 2021

Cet article s’intéresse aux usages et à la pertinence de la notion d’ignorance dans les recherches contemporaines en alimentation. L’analyse de la littérature nous conduit à distinguer trois mécanismes de production de l’ignorance : 1) l’ignorance comme ressort psychologique individuel face aux situations de dissonance cognitive, avec le « paradoxe de la viande » ; 2) l’ignorance organisée et produite par des acteurs du domaine agro-alimentaire aux États-Unis, en vue de peser sur le débat scientifique et la représentation que se fait le grand public des effets du sucre sur la santé ; 3) l’ignorance comme épistémicide en analysant les processus qui ont présidé et président encore à la disparition de savoirs traditionnels en alimentation détenus par les peuples autochtones du Canada. Dans chacun des cas, nous pointons des actions ou initiatives permettant d’enrayer ces mécanismes de production de l’ignorance.
Concrétiser l’ambition démocratique de l’alimentation durable ?
Authors: Damhuis Lotte , Serré Alexia , Rosenzweig Matthias
Published: January 2021

Des organismes d’aide alimentaire bruxellois ont mené entre 2015 et 2018 le projet Solenprim, visant à développer des initiatives pilotes pour permettre aux personnes les plus précaires d’avoir un accès plus durable à une alimentation de qualité. Le projet repose sur le constat que les mouvements qui veulent développer des systèmes alimentaires durables ne sont que peu accessibles aux personnes en situation de précarité. À la lumière des expérimentations de Solenprim, qui ambitionnait de construire des ponts entre acteurs de l’aide alimentaire et ceux de l’alimentation durable, l’article développe les raisons qui permettent de comprendre pourquoi ces mouvements peinent aujourd’hui à atteindre leurs ambitions démocratiques. Elles tiennent d’une part au référentiel moral véhiculé en matière de « manger sain et responsable ». Ces cadres normatifs ne tiennent généralement pas compte de la façon dont les situations de pauvreté peuvent affecter l’acte alimentaire dans sa complexité. D’autre part, les espaces et initiatives qui offrent des produits alimentaires durables reproduisent, malgré eux, des barrières financières et socio-culturelles qui tendent à les rendre inaccessibles aux personnes en situation de pauvreté.

The Roman city of Pollentia was founded in 123 BCE in the northern part of the island of Mallorca (Balearic Islands, Spain). The city developed through the Republican and Imperial periods. At the end of the third century CE, a large fire destroyed parts of the city, although it survived through the Vandal and the Byzantine periods. At the beginning of the tenth century, the Balearics were conquered by the Muslim forces. Recent excavations of the Late Roman fortification located at the area of the forum have revealed some layers with large quantities of utilitarian ceramics dated to the Islamic period. An archaeometric study was carried out to characterize these products, their provenance and technology. This was completed by utilizing a combination of techniques, including: Wavelength Dispersive X-Ray Fluorescence (WDXRF), X-Ray Diffraction (XRD) and Optical Microscopy by thin-section analysis (OM). The results show two main compositional groups, one of which might be local and a second one regional. This is a first step on the compositional characterization of utilitarian pottery from Pollentia under the Islamic rule, and contributes to a progressive and systematic characterization of ceramics from this particular period on the island.

Published: January 2021

Depuis trente ans, les milieux d’altitude européens constituent un cadre novateur de recherche sur les dynamiques des systèmes pastoraux des espaces de montagne dans la longue durée. Les différentes équipes de recherche impliquées dans ces travaux se trouvent confrontées au problème de l’acquisition de l’information primaire lors de la phase de prospection. Accéder à une information archéologique qui soit la plus complète possible dans un temps relativement court est l’enjeu de la phase de prospection en milieu d’altitude. Le programme de recherche TAHMM (Télédétection Archéologique en Haute et Moyenne Montagne) a pour objectif de réviser les méthodes de détection des structures archéologiques de ces milieux en déployant différentes méthodes non invasives, du satellite à l’analyse chimique des sols, pour mettre en place une approche intégrée multi-source, multi-échelle et multi-temporelle. Établir de nouvelles procédures de prospection demande également de pousser plus avant l’analyse de l’information et souvent de sortir des schémas trop stricts des formats propriétaires. Le présent article exposera les premiers résultats du travail de refonte de la chaîne de traitement et d’analyse des images thermiques acquises par drone sur des sites pastoraux d’altitude en s’appuyant sur des tests réalisés en 2018.

IL-17–secreting Th17 cells play an important role in the pathogenesis of various inflammatory and autoimmune diseases. IL-17–targeted biologics and small molecules are becoming promising treatments for these diseases. In this study, we report that SZB120, a derivative of the natural compound 3-acetyl-β-boswellic acid, inhibits murine Th17 cell differentiation by interacting with the α-subunit of eukaryotic initiation factor 2 (eIF2α). We showed that SZB120 directly interacts with eIF2α and contributes to serine 51 phosphorylation of eIF2α. The suppressive effect of SZB120 on Th17 cell differentiation was reversed by GSK2606414, an inhibitor of eIF2α phosphokinase. Phosphorylation of eIF2α induced by SZB120 decreased the protein expression of IκBζ, which is important for Th17 cell differentiation. Notably, interaction with eIF2α by SZB120 also impaired glucose uptake and glycolysis in T cells. In vivo, SZB120 treatment of C57BL/6 mice significantly attenuated IL-17/Th17–mediated autoimmune disease. Our study indicates that SZB120 is a promising drug candidate for IL-17/Th17–mediated inflammatory diseases.

Background: Immunization has remained the most cost effective strategy of reducing global childhood deaths and disabilities. The diseases and illnesses targeted by the process of vaccination to achieving immunization are termed Vaccine Preventable Diseases (VPD). Vaccine preventable diseases constitute a major burden to under-five morbidity and mortality in developing countries like Nigeria.This key strategy is being hindered by factors such as forgetfulness and accessibility challenges among others. This study seeks to evaluate the place of using remindersin the form ofShort Message Services (SMS) and or phone calls in improving health seeking behavior through immunization.

Materials and Methods: A questionnaire based cross sectionalstudies was carried out between 1st of July to the 31st of December 2019 on the Children Medical Wards of the DalhatuAraf Specialist Hospital. The role of SMS and preference of care-givers between SMS and phone calls on immunization activities was determined. Data analyses were done using the Statistical Package for Social Sciences (SPSS) version 20.

Results: The mean age of mothers in this study is 27.58±5.82 years, as most mothers (58.5%) were aged between 21-30 years. Almost all of the responders in this study were married except two (one single mother and a widow respectively). More than 90% had a phone. In spite of this, one fifth of the mothers agreed to have missed immunization at some point. Most (82.2%) of the responders believed using SMS as a reminder will reduce the rate of missed immunization. Loss of immunization cards and forgetfulness were the leading reasons for missed immunization in this study.

Conclusions: Most mothers in the present study believed SMS will reduce the rate of missed immunization and preferred it to phone calls.

Venous Thromboembolism (VTE), is a major health concern that has continued to pose a challenge to clinicians. It is a major cause of morbidity and mortality in our environment. In recent years there has been renewed attention on the need for thromboprophylaxis to prevent VTE and its consequences. This is a prospective study carried out on the gynaecological in patients of Bowen University Teaching Hospital, Ogbomoso. This study involved the use of a questionnaire with the details of the Caprini score in assessing patients. Our study revealed that 83 (58.5%) patients had low risk for VTE while 55 (38.7%) had moderate risk for VTE. Only 4 (2.8%) of participants had a high risk for VTE and none of the gynaecological patients could be classified as very low risk according to the Caprini index. There is a need to train and retrain health care givers on the importance of thromboprophylaxis. This training should include the development of local protocols similar to international guidelines meeting the local needs, this will go a long way to ensure it is user friendly to healthcare workers.

Published: January 2021

Background: Hydroxyproline is one of the biochemical markers that can be measured objectively as an indicator of normal biological processes or pathological processes. It is usually raised in disease conditions that are associated with bone resorption. Aim: To determine the urinary hydroxyproline/creatinine levels in a study population of healthy Nigerians. Methods: This study recruited 22 consenting participants who served as control for another study at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu. All participants were required to fast for at least 12 hours overnight and their early morning second void urine collected between 7am and 8am. The collected urine samples were stored frozen at -20oC until analysis. Colorimetric method of analysis of urinary hydroxyproline and creatinine were done using Biovisionhydroxyproline kit and Randoxcreatinine kit respectively. Bivariate analysis was conducted on the collated data using statistical package of social science (SPSS) version 19. The results were recorded as urinary hydroxyproline alone (μg/μL) and as urinary hydroxyproline/creatinine ratio. Results: The mean urinary hydroxyproline level of 0.020±0.013μg/μL and urinary hydroxyproline/ creatinine ratio of 0.016±0.006 were noted for healthy Nigerians. Conclusions: The urinary hydroxyproline levels in the study population of healthy Nigerians are within normal values reported in other healthy populations.
La medicina e la morte
Authors: De Caprio Lorenzo , Di Palma Annalisa
Published: January 2021

La morte ha occupato in ogni epoca una posizione centrale nella medicina, e la sua stessa storia dimostra come l’impegno del medico a difendere ad oltranza la vita sia una peculiarità della moderna medicina scientifica. D’altra parte, nel passaggio da una società retta da valori tradizionali a quella moderna, gli storici registrano profondi mutamenti nel rapporto tra l’uomo e la morte. Mentre la cultura dominata dalla tradizione religiosa, pur difendendo la vita, accettava la morte come limite dell’uomo e parte integrante della condizione umana; la cultura della Modernità, nella sua ansia di dominare il mondo, ha rimosso e combattuto la morte. Quindi, solo interventi tesi ad introdurre valori umani e morali nella formazione del medico potrebbero riportare “senso” in una pratica medica che rispecchia fedelmente l’ideologia ed i valori di una società dominata dalla ragione tecnico-scientifica.

I1 progresso tecnologico ha messo a disposizione dei medici mezzi capaci di salvare vite umane, ma, per l’oblio di misure umane e morali, con gli stessi mezzi, i medici si accaniscono prolungando inutilmente l’agonia del morente. I1 progresso tecnologico sembra così ritorcersi contro l’uomo. I1 dibattito bioetico aspira a ridare dignità al morente, ma s’è arrestato sul lacerante problema dell’eutanasia. Gli autori giudicano grave e pericolosa questa situazione di stallo; infatti, in un’epoca di limiti nelle risorse, la decisione sulla vita e sulla morte s’avvia ad essere condizionata unicamente da valutazioni d’ordine economico.
La libertà e la legge: sì o no alla vita?
Authors: Stycze´n Tadeusz
Published: January 2021

Uno dei compiti essenziali etico-culturali, davanti ai quali lo studioso di etica viene posto dall’EV, è il rendere cosciente possibilmente tutti gli uomini, come cittadini dei loro Stati, in che cosa trasformano il loro Stato come legislatore e chi diventano essi stessi e, quando tale Stato, con un atto di diritto positivo toglie – come nel caso della legalizzazione dell’aborto – da ogni tutela della legge, coloro che vengono uccisi per proteggere, con lo stesso atto, e perfino sostenere coloro che li uccidono. L’Autore in tal proposito analizza le leggi di questo tipo alla luce dell’enciclica Evangelium Vitae (EV).

L’attenzione dello studioso di etica si concentra prima sugli uomini, e in seguito sulle istituzioni da loro stessi create: legge e Stato, esaminando la loro dimensione “umana” cioè culturale.

La drammaticità della diagnosi posta dall’EV è testimoniata dalla progressiva espansione della “cultura della morte”. Ne è una prova il fatto che l’ONU, fondata al fine di superare, il primo caso nella storia dell’umanità di “legge contro la vita” (i cosiddetti decreti di Norimberga), in corrispondenza del 50° anniversario della sua esistenza, si fa promotrice del secondo caso di “legge contro la vita” – il “diritto all’aborto sicuro”. La riflessione dello studioso di etica si concentra proprio sul disfacimento della cultura come cultura di morte e ha come scopo di farne una diagnosi più differenziata, al fine di intraprendere, in base ad essa, delle “terapie” opportune, unico modo per contrastare e prevenire il fenomeno dell’estinguersi della cultura umana.
La natura e lo statuto dell’embrione umano
Authors: Colombo Roberto
Published: January 2021

L’articolo argomenta sulla appartenenza dell’embrione umano alla categoria degli esseri dotati di una vita umana personale.

Infatti, la sua soggettività umana incontra delle difficoltà nel venire accettata. Diversi mettono in dubbio che sia possibile definire l’embrione - fin dal suo stadio unicellulare - come un essere umano a pieno titolo o persona.

Il Magistero cattolico ha affrontato il problema con due argomenti: uno di carattere antropologico, basato sull’affermazione della sostanziale unità tra corpo e anima nell’essere umano e sulla evidenza biologica che dal momento della fecondazione dell’ovocita, inizia una nuova vita con una sua propria crescita. Il secondo argomento è probabilistico e si riscontra nella incontestabile osservazione di Giovanni Paolo II secondo la quale basterebbe la sola probabilità di trovarsi di fronte ad una persona per giustificare la più netta proibizione di ogni intervento volto a sopprimere l’embrione umano. Ma la natura umana dell’embrione, già dallo stadio zigotico, è testimoniata dalla genetica moderna, che ha mostrato come dal primo istante si trovi fissato il programma di ciò che sarà questo vivente.

In conclusione, le evidenze della scienza non possono, da sole e in alcun modo, attribuire all’embrione umano lo statuto ontologico di essere umano a pieno titolo o persona, perché l’essere e la persona non appartengono al campo dei concetti biologici e non sono oggetti formali di indagine empirica. La genetica e la biologia dello sviluppo suggeriscono però con sempre maggiore documentazione che l’embrione non sia altro che un individuo della specie umana nella fase iniziale del suo ciclo vitale, che lo condurrà a divenire un adulto come noi.
Bioetica dell’esercizio della sessualità nel portatore di handicap fisico geneticamente trasmissibile
Authors: Baldacci Maria Cristina
Published: January 2021

Nella maggioranza dei casi la corporeità dell'handicappato viene relegata ad una semplice rieducazione e indirizzata principalmente verso una migliore socializzazione, i sentimenti di tipo erotico sono ridotti alla sfera spirituale e sostituiti da un'affettività e da un amore platonico dettati da ideologie sociali.

Per un handicappato avere un'immagine del proprio corpo è sicuramente più difficile che per altri: il corpo è concepito come luogo di sentimenti ambivalenti. Perchè sede della propria diversità, rappresentazione di una parte di sè che non risponde ai desideri personali, sia di ordine funzionale sia relazionale.

Le persone portatrici di handicap hanno bisogno di un aiuto approppriato nella valorizzazione estetica della propria immagine data la disabilità fisica. E' necessario, quindi, aiutarli a scoprire di sè aspetti "diversamente belli" e gratificanti, non solo patinati.

Nell'ambito di questa problematica, l'autrice si sofferma particolarmente, per i problemi morali che sollevano, sulle situazioni patologiche geneticamente trasmissibili.

In questi casi è necessario far comprendere la giusta possibilità di evitare un danno altamente probabile, forse anche certo, ad una terza persona. In altre parole secondo l'autrice si deve collaborare con Dio a non generare dolore, e l'unico modo per farlo è attraverso l'educazione. E' auspicabile, infatti, che una persona affetta da patologia fonte di handicap fisico geneticamente trasmissibile non eserciti la propria genitalità, ma viva ed "inventi" l'esercizio della propria sessualità in modo sublimato e trascendente, mantenendo intatta e, se è possibile migliorando, la propria "salute sessuale" e mentale.
Una valutazione della “Convenzione sui diritti dell’uomo e la biomedicina” del Consiglio d’Europa
Authors: Bompiani Adriano
Published: January 2021

L’articolo si occupa della recente “Convenzione sui diritti dell’uomo e la biomedicina” elaborata dal Comitato Direttivo per la Bioetica (CDBI) della Comunità Europea ed approvata dal Comitato dei Ministri europei nel novembre del 1996.

Premesso che il testo approvato andrà implementato da protocolli esplicativi dei principi affermati nella Convenzione stessa, l’autore traccia un breve excursus storico del documento analizzando le ragioni che ne hanno giustificato la stesura, i criteri generali adottati ed i principi etici fondamentali che hanno ispirato l’articolato.

L’analisi della Convenzione procede nel tentativo di dare risposta ai seguenti quesiti: Come valutare la Convenzione in merito ai contenuti? a quali principi e criteri etici corrispondono le proposte della Convenzione? e, infine, quali sono gli aspetti che riguardano gli obblighi degli Stati firmatari, i meccanismi di controllo, quali le riserve ed interpretazioni dello strumento internazionale?

In breve, l’ultima parte del lavoro può riassumersi nel seguente modo: 1. il testo della Convenzione risulta apprezzabile in alcuni punti (come nell’affermazione della necessità di protezione dell’essere umano, che rimane prioritario rispetto agli interessi della società) e discutibile in altri (quali, ad esempio, la tutela della vita prenatale, la tecniche di procreazione artificiale, l’assistenza ai morenti, ecc.); 2. la Convenzione si rifà ai principi etici di una medicina attiva, tecnologica e sperimentale diffusi largamente nel mondo anglosassone, il cosiddetto “principialismo”; 3. vengono stabilite delle procedure volte a garantire l’adempimento delle affermazioni contenute nella Convenzione, anche se gli Stati membri possono, al momento della ratifica, formulare riserve nel caso in cui una legge in vigore sul proprio territorio non sia conforme alla disposizione della Convenzione.

Published: January 2021

Background:

To clarify the changes in the echo intensity (EI) in the prefemoral fat pad (PFP) and identify the relationship between the PFP and clinical features of knee osteoarthritis (OA).

Methods:

Twenty-six women with knee OA (mean age: 76 years) and 17 healthy women (mean age: 73 years) were enrolled. The Kellgren and Lawrence grading scale was used for the radiographic evaluation of knee OA. The EI of the PFP was measured as grayscale values. The change ratio of the anteroposterior PFP length during quadriceps contraction was measured. Knee range of motion and pain (100-mm visual analog scale) were evaluated.

Results:

The EI was significantly higher in the OA group than in the healthy group (P < 0.001). The change ratio of the PFP in the OA group was significantly lower than that in the healthy group (P < 0.001). The ranges of knee flexion and extension were correlated with the EI of the PFP (both P < 0.01) and the change ratio of the PFP (both P < 0.01). There was no significant correlation observed with knee pain.

Conclusion:

Hyperechoic changes and a decreased change ratio of the PFP were observed in the patients with knee OA. High EI and decreased morphological PFP changes were associated with decreased ranges of motion.
Aerodynamic Investigation of Morphing Wing UAV with Adjustable Slotted Airfoil Configuration
Authors: Jiniraj R. , Raman R. Venkat , Dinesh N.
Published: January 2021

Aviation has wide aspects to challenge and discover, the ability to land and take off at slow speed, sudden increase in drag for short runway landings. This paper puts forth the solution by the use of adjustable multi slots configuration of an airfoil. In this case, the slots extend from the wing leading edge to trailing edge. This causes change in the chord, thereby changing the camber of unsymmetrical airfoil. An investigation was made to determine and compare the aerodynamic characteristics of multi slotted adjustable airfoil with unmorphed unsymmetrical airfoil at varied speeds and Angle of Attack (AoA). There are three slots distanced equally along the airfoil. The extension of these slots increases the chord length by 10% of total chord. The slotted and unslotted airfoil profile are then studied using computational fluid dynamics of external flow over a body. The flow simulation is done at 10m/s, 20m/s, 30m/s, 40m/s and 50 m/s flow velocity and at 0, 3, 6, 9 ,12, 15 AoA. The results were obtained for each case and the values for base and slotted model were compared. It was found that lift of slotted model is slightly higher than base model at low flow velocity. It was also seen that the use of slots at high speed causes a large amount of drag. This increased drag factor can be used in UAVâ€™s as spoilers during landing or for landing at shorter runways at lower speed, allowing a sudden decrease in aircraft speed and also to glide at a steeper angle over obstruction.
Optimal Method for Determination of Rayleigh Damping Co-efficients for Different Materials using Modal Analysis
Authors: Rahul B. , Dharani J. , Balaji R.
Published: January 2021

Rayleigh damping co-efficients are the essential parameters to determine the damping matrix of a system in dynamic analysis. For the systems with multiple degrees of freedom, it is difficult to arrive for suitable Rayleigh damping co-efficients. This paper represents a simple and effective method for the determination of Rayleigh co-efficients Î± and Î² for the system with multiple degrees of freedom. An unrealistic constant damping ratio for all modes is assumed to get rational value of Î± and Î², which leads the determination of progressively varying damping ratio for all modes. By comparing the damping ratio arrived from assumed Î± and Î² with assumed unrealistic damping ratio, the suitable and most precise values are determined. This method is implemented for different materials with different boundary conditions by considering different significant modes and the effect of above parameters on Î± and Î² values are also discussed.
Comparison of disinfectants for drinking water: chlorine gas vs. on-site generated chlorine
Authors: Choi Yonkyu , Byun Seung-Heon , Jang Hyun-Jung , Kim Sang-Eun , Choi Young-june
Published: January 2021

The feasibility of on-site generated chlorine (OSG chlorine) as an alternative disinfectant to chlorine gas was evaluated in terms of total organic carbon (TOC) removal, disinfection efficiency, biofilm control, disinfection by-products (DBPs) formation, chlorine decay rate, and volatility. Chlorine gas decreased the pH of the treated water by -0.1 per mg/L of free available chlorine (FAC) while OSG chlorine increased the pH by + 0.06 per mg/L. OSG chlorine with more hypochlorite ion (OCl-) at higher pH was less effective in the inactivation of suspended bacteria and TOC removal but remained in the distribution system longer and controlled biofilm formation more effectively than chlorine gas. The DBPs formation by OSG chlorine was not significantly different from that by chlorine gas except for the reduction of Haloacetonitriles. Hypochlorous acid (HOCl) was more volatile than OCl-, indicating the lower volatility of FAC in the OSG chlorine-treated water. Two types of OSG systems, “Mixed oxidants” and OSG hypochlorite, did not show any significant difference in disinfection, DBPs formation, and chlorine decay rate (paired t-test, p = 0.40, 0.11 ~ 0.70, > 0.42). A significant synergy effect by oxidants other than FAC cannot be expected in the use of “mixed oxidants” at a water treatment plant.
A cognição e os princípios teóricos e metodológicos ao ensino de Libras para ouvintes
Authors: Silva Lídia Da
Published: January 2021

Atualmente, a maioria dos trabalhos relacionados ao ensino de Libras para ouvintes ancora-se na perspectiva social para discutir questões de ordem teórico-metodológica. Este ensaio propõe uma reflexão a partir do viés cognitivo e, para tanto, apresenta princípios teóricos que estão calcados no conexionismo (Mota; Zimmer, 2005; Leite, 2008). Apresenta também princípios metodológicos que se respaldam no modelo computacional de aquisição de L2 de Ellis (1998) àqueles professores com pouca experiência em sala de aula. Nesse modelo, as questões metodológicas ancoram-se na concepção de instrução, sendo que essa pode ser baseada no input, na forma, na produção e no feedback. As instruções são ilustradas com recomendações didáticas encontradas na literatura especializada. Os argumentos apontam para uma visão integrativa entre fatores biológicos e experiência empírica, e para a indicação de que a instrução formal pode otimizá-los.
Uma proposta para a análise crítica do meme como gênero em aulas de língua portuguesa
Authors: Oliveira Nara Maria Alves de , Bezerra Benedito Gomes , Lêdo Amanda Cavalcante de Oliveira
Published: January 2021

O advento das Tecnologias Digitais de Informação e Comunicação suscitou novas práticas de leitura e de escrita. Essas novas práticas geraram inquietações sobre como a escola, uma das principais agências de letramento, pode se apropriar dos recursos necessários para garantir processos de ensino-aprendizagem significativos e coerentes com as demandas da sociedade contemporânea. No campo da Linguística Aplicada, estudos como os de Ribeiro (2015) e Rojo e Moura (2012) sugerem a necessidade de se criarem estratégias metodológicas que permitam desenvolver os letramentos dos estudantes, em consonância com o que preconizam documentos norteadores da educação no país, tais como a Base Nacional Comum Curricular (BRASIL, 2018). Assim, neste artigo, apresenta-se uma proposta pedagógica para a abordagem crítica do meme como gênero em sala de aula de língua portuguesa, voltada para estudantes dos anos finais do Ensino Fundamental. O objetivo do trabalho é propor um estudo reflexivo do gênero a fim de despertar a consciência crítica dos discentes, por meio da análise do meme segundo as metáforas de partícula, onda e campo. Adota-se, para isso, um aporte teórico ancorado nos Estudos Retóricos de Gênero (BAZERMAN, 2006; MILLER, 2012), aliado a procedimentos metodológicos baseados em uma pedagogia tríplice (DEVITT, 2009) para o ensino e aprendizagem crítica do gênero. Como resultado da implementação da proposta, espera-se que os estudantes percebam o gênero não apenas como uma entidade isolada, mas também em suas inter-relações com gêneros antecedentes e situados em contextos específicos.

O objetivo deste trabalho é analisar, com base na teoria dialógica em conjunto com a teoria da argumentação, o valor da sustentabilidade na publicidade de uma instituição bancária privada. Foram verificados os valores, a hierarquia de valores e os lugares da argumentação a partir das ocorrências nos textos. Os resultados mostram que o valor da sustentabilidade encontra-se em uma estrutura hierarquizada com os outros valores, e prevalecem os lugares de qualidade e quantidade. Além disso, as marcas linguísticas demonstram a inclusão do Banco como agente sustentável, e um endereçamento da responsabilidade social e das práticas sustentáveis a outros agentes, os clientes. Por fim, enfatiza-se a necessidade de recuperar o contexto para a compreensão das relações dialógicas existentes nos enunciados.

Trata-se de uma pesquisa que procura entender as articulações entre os ilegalismos populares e as formas do controle social a partir de trabalho de campo realizada no setor do transporte clandestino em São Paulo. Para tanto, procurou-se acompanhar as transformações no setor durante o período que se estende à criação da agência reguladora do transporte na cidade (SPTrans) e a regularização dos chamados “perueiros”. Essas transformações, que alteraram significativamente os instrumentos de ação estatal no setor, também reorganizaram a dinâmica dos grupos que disputam e negociam o circuito do transporte na cidade, dentro e fora do ordenamento jurídico.
An ontology for threat modeling and simulation of Small Unmanned Aerial Vehicles
Authors: Chhaya Bharvi , Jafer Shafagh , Proietti Paolo
Published: January 2021

Low, Slow and Small Unmanned Aerial Vehicles (LSS UAVs) are one of the fastest-growing threats for national defense, security and privacy. A NATO task group performed a study to identify the elements necessary to define LSS models applicable for the development of necessary countermeasure to potential threats in the future. The goal of this project is to utilize this data collected by the NMSG-154 study to generate a Web Ontology Language (OWL) ontology for LSS threat modeling. The LSS ontology will form the basis for a metamodel for a domain-specific language (DSL) based on the parameters identified. This DSL will eventually be used to generate specific simulation scenarios to model potential threats caused by small drones.

Published: January 2021

A modelling and simulation (M&S) approach was earlier developed, following statistical analysis of the emergency incident database of the Vaughan Fire & Rescue Service covering eight years of consecutive incident records from January 2009 to December 2016. The M&S framework, which could potentially be replicated for fire departments across Canada, involved two different simulation models running on separate platforms: (i) an Incident Generation Engine, which simulates the ‘arrival’ of emergency incidents, and (ii) a Response Simulation Model. The current report covers only an update of the Response Simulation Model, an agent-based model developed using AnyLogic. Two issues associated with the earlier Response Simulation Model have specifically been addressed and resolved by the updated model. We report on findings from our simulation experiments based on the updated model.

The article deals with the response to crisis situations in road transport. Crisis situations are recorded in every critical infrastructure sector. Road transport is no exception. The material transported annually records the growth. The planning of the transport does not take into account the risk of the planned route or the categorization of the transport unit. When categorizing the transport unit the limited choice of suitable routes. The article is focused on real-time responsiveness to crisis situations. The purpose is to minimize next risks that could result in more and more serious events when one crisis situation arises.
Realization of food defense and food security standards in Polish maritime transport
Authors: Kaczmarczyk Barbara , Nowicka Izabela
Published: January 2021

This article touches on the issue of Food Defense and Food Security in Polish maritime transport. It seems indispensable to refer to the food defense as any action that the company must take to prevent the intentional contamination of food products by biological, chemical, physical or radiological factors which cannot be expected based on hazard analysis and which may arise in connection with human activities as a source of contamination (FDA). Temperature-controlled food transport is one of the most critical elements in today's supply chain, which is reflected in an increase in the demand for fresh and frozen products. In the case of sea transport, this will require temperature control in refrigerated containers. The effect of research on the impact of the stream of descending air and its free passage on the duration of storage of natural food products, which are presented in the article, are guidelines contained in military procedures.
