Authors: Preci Gjon , Zekja Iliriana , Kruja Jera , Abazaj Erjona
Published: February 2022

BACKGROUND: Dementia itself is not a disease, but a constellation of symptoms caused by diseases and disorders that affect the brain. Dementia and depression are mental health problems commonly encountered in neuropsychiatric practice in the elderly.

AIM: The aims study was to evaluate the prevalence of depression in elderly people with dementia and to see the association between them.

METHODS: This is a retrospective cohort study associating dementia with depression among the population from 50 until to more than 85 years old in Shkodra City in Albania. Practically, the figure of 187 patients with dementia was selected using the cluster sampling method. Patients were considered to have depression when one or more ICD codes for depression were recorded as primary or secondary diagnosis. Multilogistic regression odds ratio (OR) was used to identify factors predicting severity of depression.

RESULTS: A total figure of 187 patients with dementia were enrolled into the study for a period of 4 years. Approximately, the minimum age was 50 and maximum 89 years old with average 75 ± 8.1 std. The prevalence of depression among those patients with dementia resulted 44.9% (84/187). Almost 61% of patients had moderate depression and 28% of patients had severe depression. According to studies, male with dementia was the most predominant sex compared to female with percentage 60.4% and 39.6%, respectively. On the other hand, depression was being found more predominant to female patients with dementia, not to forget that female was 2.9 (OR) time in risk to develop depression compared to male 95% CI (1.6–5.4) p = 0.0005. We did not find a strong association between the late-life depressions than in depression in middle-aged adults.

CONCLUSION: Depression in older adults is a serious concern, especially in dementia population, which often is underdiagnosed being masked by cognitive impairments. According to the case in question, the findings highlight a high prevalence of depression within the dementia patients. After numerous medical researches, we found a strong association between depression and gender, lifestyle, type, or residence with the dementia patients. As stated, the better knowledges in the interactions between the depression and dementia from the part of medical staff will likely contribute to the timely prevention, identification, and treatment of depression in the elderly and will influence on their quality of life.
L’art contemporain au service du pédagogue de l’audit
Authors: Rocher Sébastien
Published: February 2022

Souhaitant faire oublier le caractère parfois rebutant de la comptabilité, de nombreux pédagogues ont cherché dans différents médiums culturels des références permettant d’expliquer la comptabilité par un décalage du regard. Le présent article se veut une proposition d’étendre cette démarche à la pédagogie de l’audit, une pratique pouvant également apparaître comme peu attrayante. Pour ce faire, cet article propose une analyse de 4 œuvres d’art contemporain dans lesquelles l’artiste a soit fait appel à un auditeur, soit s’est approprié la pratique de l’audit, afin de mettre en évidence ce qu’elles révèlent de l’audit, de son fonctionnement, de ses enjeux et de ses limites.

Early Exposure to Bilingualism and Subsequent School Trajectories
Authors: Vigezzi Serena , Panico Lidia , Grobon Sébastien , Remillon Delphine
Published: February 2022

Plusieurs hypothèses ont été avancées au sujet des effets potentiels du bilinguisme sur le développement cognitif des enfants et leur réussite scolaire. Toutefois, peu d’études cherchent à les départager empiriquement, et la littérature existante est essentiellement consacrée aux États-Unis. Dans cet article, nous utilisons une enquête récente, représentative des adultes résidant en France (l’enquête « FQP » – «  Formation et Qualification professionnelle » ) pour étudier la corrélation entre l’exposition à un environnement bilingue à l’âge de 5 ans (qu’il s’agisse d’une langue régionale ou étrangère) et la trajectoire scolaire ultérieure. Nous explorons aussi si cette association varie en fonction des différentes caractéristiques de cette population. Nous montrons qu’une exposition bilingue précoce est associée à une moindre réussite scolaire, particulièrement en fin de parcours scolaire. Cette corrélation négative est plus forte parmi les individus d’origine maghrébine, et à l’inverse moins marquée chez les individus originaires d’Europe du Sud. Elle concerne aussi ceux qui ont été exposés à une langue régionale dans l’enfance. Enfin, ce désavantage est proportionnellement plus marqué chez les individus dont les parents sont les plus diplômés. Ces résultats montrent l’importance d’étudier les corrélations entre l’exposition au bilinguisme et les trajectoires scolaires en tenant compte de l’hétérogénéité des caractéristiques des individus concernés.

Published: February 2022

The current study aims at exploring the beneficial effect of silica fume (SF) and acrylic emulsion polymer (PR) on the enhanced properties of polypropylene fiber reinforced concrete (FRC) with the supplementary cementitious binder comprised of the Portland cement, slag, silica fume and fly ash. The compressive strength and impact-abrasion resistance were used for the estimation of engineering properties while the water absorption performance, surface electricity resistance, and rapid chloride penetration resistance were used for estimation of durability. Experimental results showed that a sole addition of SF increased the compressive strengths but decreased the abrasion-impact resistances of modified FRCs, which was just opposite to the influence of a sole addition of PR. A sole addition of either the SF or PR could moderately improve the durability of modified FRCs, respectively. However, due to the beneficial effect of the complementary interaction between SF and the optimal amount of PR, the mechanical properties and durability of modified FRCs seemed to become significantly improved.
Comment la connaissance de la diversité posturo-locomotrice des primates a-t-elle transformé la compréhension de celle des hominines ?
Authors: Lequin Mathilde , Marchal François
Published: February 2022

Au cours des dernières décennies, la manière dont les paléoanthropologues conçoivent la bipédie s’est considérablement modifiée. Si la bipédie a jadis pu être pensée comme une caractéristique unique, propre à la lignée des hominines et marquant son origine, l’hypothèse de sa diversité anatomique et comportementale, envisagée dès les années 1960, est aujourd’hui largement admise. Cet article d’histoire et de philosophie des sciences se propose d’analyser la contribution de la primatologie à la transformation du cadre théorique employé en paléoanthropologie pour penser l’évolution de la bipédie. Alors que les découvertes fossiles sont souvent présentées comme l’élément moteur du changement théorique dans cette discipline, nous montrons que les études sur la diversité locomotrice des primates ont également joué un rôle fondamental pour déconstruire certains schémas interprétatifs fréquemment utilisés dans l’analyse des restes fossiles d’hominines. À travers notre approche épistémologique, nous montrons comment les méthodologies novatrices employées en primatologie peuvent constituer des outils conceptuels et analytiques susceptibles d’être mobilisés en paléoanthropologie. Ces outils permettent de s’affranchir d’un certain anthropocentrisme fondé sur l’équivalence entre bipède et hominine et par conséquent de proposer de nouvelles hypothèses quant à l’origine et l’évolution de la bipédie.
Multi-Objective Optimization-Oriented Resource Allocation in the Fog Environment
Authors: Harika Sonti , Krishna B. Chaitanya
Published: February 2022

Fog computing is a decentralized computer system where data, processing, storage, as well as applications are located anywhere between the cloud and data source. Fog computing takes the cloud closer to users, decreasing the latency and allows the deployment of new delay-sensitive appliances. An important feature of a fog-cloud network is the process of decision-making on assigning the resources to execute the tasks of application. This paper aims to propose a resource allocation strategy for fog computing that determines the effective process under the consideration of the objectives that includes the constraints like credibility score, concurrency, price affordability and task time computation. Moreover, the credibility score is determined based on the execution efficiency, Service response rate, access reliability and Reboot rate. Thereby, the optimal allocation of resources is handled by a new Hybrid Monarch-Dragon Algorithm (HM-DA) that hybrids the concept of Dragonfly Algorithm (DA) and Monarch Butterfly Optimization (MBO) algorithm.

Published: February 2022

Phony news or fake news spreads like a wildfire on social media causing loss to the society. Swift detection of fake news is a priority as it reduces harm to society. This paper developed a phony news detector for Reddit posts using popular machine learning techniques in conjunction with natural language processing techniques. Popular feature extraction algorithms like CountVectorizer (CV) and Term Frequency Inverse Document Frequency (TFIDF) were implemented. These features were fed to Multinomial Naive Bayes (MNB), Random Forest (RF), Support Vector Classifier (SVC), Logistic Regression (LR), AdaBoost, and XGBoost for classifying news as either genuine or phony. Finally, coefficient analysis was performed in order to interpret the best coefficients. The study revealed that the pipeline model of MNB and TFIDF achieved a best accuracy rate of 79.05% when compared to other pipeline models.

Geology and geochemistry of mafic and ultramafic bodies in the Shebandowan mine area, Wawa-Abitibi terrane: implications for Ni-Cu-(PGE) and Cr-(PGE) mineralization, Ontario and Quebec
Authors: Kuster K , Lesher C M , Houlé M G
Published: February 2022

The Shebandowan Ni-Cu-(PGE) deposit occurs in the Shebandowan greenstone belt in the Wawa-Abitibi terrane. This deposit is one of a few economic Ni-Cu-(PGE) deposits in the Superior Province and one of a very few deposits worldwide that contains both Ni-Cu-(PGE)
and Cr-(PGE) mineralization. The mafic-ultramafic successions in the area comprise abundant flows and sills of tholeiitic basalt and lesser Al-undepleted komatiite (MgO >18 wt%, Al2O3/TiO2 = 15-25), the latter indicating separation from mantle sources at shallow levels. Siliceous
high-Mg basalts (MgO 8-12 wt%, SiO2 > 53 wt%, TiO2 < 1.2 wt%, La/Sm[MN] < 1-2) are relatively abundant in the area and likely represent crustally contaminated komatiites. Ultramafic bodies in the Shebandowan mine area comprise at least three or four
komatiitic sills (A-B, C, D) and at least two komatiitic flows (E, F), all of which are altered to serpentinites or talc-carbonate schists with relict igneous chromite and rare relict igneous orthopyroxene-clinopyroxene. Unit A-B contains pentlandite-pyrrhotite-chalcopyrite-pyrite-magnetite
mineralization, occurring as massive sulfides, sulfide breccias, or stringers, and subeconomic chromite mineralization in contorted massive bands varying from a few millimetres up to 10 metres thick. The localization of massive and semi-massive Ni-Cu-(PGE) ores along the margins of Unit A and the
paucity of disseminated and net-textured ores suggest tectonic mobilization. Chromite is typically zoned with Cr-Mg-Al-rich (chromite) cores and Fe-rich (ferrichromite/magnetite) rims due to alteration and/or metamorphism, but rarely contains amoeboid magnetite cores. The thickness of chromite in
Unit B is too great to have crystallized in cotectic proportion from the komatiitic magma and a model involving dynamic upgrading of magnetite xenoliths derived from interflow oxide facies iron formations is being tested.
Multisystem Inflammatory Syndrome in Adults - In COVID-19
Authors: Kamath Vasantha , Nivea B. , Sheeba R.
Published: February 2022

The spectrum of COVID-19 continues to evolve, uncovering several manifestations with every passing day. One of the complications is multisystem inflammatory syndrome (MIS) that occurs both in children and adults. MIS in children (MIS-C) has become a recognized syndrome, whereas a parallel syndrome in adults (MIS in adults [MIS-A]) has not been yet well defined. Due to the overlap between COVID 19 and MIS-A, we tend to miss cases of MIS-A. In this review, we have focused on MIS-A, its diagnostic criteria, pathogenesis, treatment, its relationship with vaccination, and differentiation from COVID 19.
Correlation of Platelet Counts with Coronavirus Disease 2019 Outcome in the Second Wave at a Tertiary Care Center
Authors: Rajanna Avinash H. , Ramanna Binduraj , Bellary Vaibhav S.
Published: February 2022

Background:

A novel coronavirus, severe acute respiratory syndrome coronavirus 2, was first identified in December 2019 as the cause of a respiratory illness designated coronavirus disease 2019 (COVID-19). Laboratory parameters particularly the inflammatory markers such as D-dimer, C-reactive protein, ferritin, and others have been studied extensively and have been applied in categorizing the disease severity as well. However, studies regarding the role of platelet counts in the disease pathophysiology are limited.

Aims

(1) To assess platelet counts in COVID-19 patients, (2) To correlate platelet counts with clinical outcome of COVID-19 patients.

Materials and Methods

The present study was conducted on 200 patients admitted to ESIC MC and PGIMSR MODEL HOSPITAL, Bengaluru, during the study period from August 2020 to July 2021. Data were collected from case files of patients presenting to the Department of General Medicine Triage and COVID Ward/intensive care unit at ESIC Bangalore, fulfilling the inclusion criteria.

Results

The mean platelet counts of the patients admitted with COVID-19 are 2.18 ± 1.32 × 105/mm3. Platelets among those who were discharged were 2.16 ± 1.09 × 105/mm3 and those among those who died was 1.71 ± 0.56 × 105/mm3. This difference was statistically significant with a P = 0.03. We also see that the lymphocyte counts are 14.03 ± 10.75% among those who were discharged and 10.13 ± 5.89% among those who succumbed to death.

Conclusion

The present study concludes that COVID-19 patients with thrombocytopenia and lymphopenia are at increased risk of mortality. Hence, platelet count and lymphocyte count can be taken as prognostic indicators of COVID-19.

Published: February 2022

Patients with chronic kidney disease can have many dermatological manifestations. One of the very rare conditions is porphyria cutanea tarda (PCT), which manifests with hyperpigmentation of skin and photosensitivity along with painful bullae in sun-exposed areas. It is due to deficiency of uroporphyrinogen III decarboxylase enzyme which takes part in heme synthesis. The deficiency could be genetic or sporadic. Iron therapy and hepatitis C infection are known to precipitate these lesions. We report a case of PCT in a woman undergoing chronic maintenance hemodialysis, review the literature, and discuss the problems with management specific to the dialysis population.

Prognostic significance of novel inflammatory markers in extensive-stage small-cell lung cancer
Authors: Yilmaz Hatice , Yersal Özlem
Published: February 2022

Objective:

Novel hematological inflammation-based parameters, such as neutrophil-to-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), prognostic nutritional index (PNI), lymphocyte-to-C-reactive protein ratio (LCR), systemic inflammatory response index (SIRI), and hemoglobin-to-red cell distribution width ratio (HRR), have been determined to be linked to prognosis of various cancer types, although the predictive impact of these parameters on extensive-stage small-cell lung cancer (SCLC) is not exactly known. In this study, we aimed to demonstrate the prognostic significance of these novel parameters.

Materials and Methods:

This retrospective study included 162 patients who were under follow-up with a diagnosis of extensive-stage SCLC. The receiver operating characteristic curve analysis revealed that the optimal cutoff values for NLR, SII, PNI, LCR, SIRI, and HRR were 2.34, 787, 46.13, 0.29, 1.5, and 1.05, respectively. Cox regression analyses were done to determine the predictive impact of these parameters on progression-free survival (PFS) and overall survival (OS).

Results:

Patients with higher LCRs and HRRs had longer PFS and OS than patients with lower LCRs and HRRs (P < 0.001, P < 0.001, P < 0.001, P < 0.001, respectively). PFS and OS were significantly shorter in the group with high SIRIs than in the group with low SIRIs (P < 0.001, P < 0.001, respectively). A multivariate analysis identified LCR and SIRI as independent prognosticators for both PFS and OS (P < 0.001, P < 0.001; P = 0.002, P < 0.001, respectively), and HRR as an independent prognostic factor only for OS (P = 0.046).

Conclusion:

LCR, SIRI, and HRR are independent prognostic parameters that predict survival times in patients with extensive-stage SCLC.

Published: February 2022

Background:

Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic liver disease that primarily affects females more than males and may lead to end-stage liver disease. We studied baseline characteristics, and the biochemical and clinical response to ursodeoxycholic acid (UDCA), a first-line treatment option for patients with PBC, in a cohort of patients diagnosed with PBC from Saudi Arabia.

Methods:

A total of 30 patients meeting the diagnostic criteria of PBC who were being followed in the King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia, between January 1, 2008, and December 31, 2017, were enrolled in the study. The patients with autoimmune hepatitis, primary sclerosing cholangitis, and overlap syndromes were excluded. The baseline characteristics of the patients were recorded. The response to UDCA treatment was assessed according to the Barcelona, Paris I, Paris II, and Toronto criteria, and clinical outcomes, and biochemical changes were ascertained.

Results:

The mean age was 46 years ± 11.7 with a female gender predominance of 93% (n = 28). Pruritus was the predominant symptom reported by 90% (n = 27) of the patients. A total of 23 (77.7%) patients underwent liver biopsy and all of them showed histological features suggestive of PBC. Cirrhosis was documented in 30% (n = 9) of the patients at baseline. Overall, 86.7% (n = 26) of the patients were positive for antimitochondrial antibodies. The biochemical response rates to UDCA based on Paris I, Paris II, Barcelona, and Toronto criteria were 73.3, 40, 56.7, and 53.3%, respectively.

Conclusion:

Over 10 years, 30 patients with PBC were diagnosed at a large referral center in Saudi Arabia. The response to UDCA treatment was inadequate.

A Macroscopic Traffic Model-based Approach for Sybil Attack Detection in VANETs
Authors: Vikas Kumar Garg, Arshdeep Singh and Pranab Garg
Published: February 2022

Vehicular Ad Hoc Network (VANETs) are required to play a significant job in our lives. They will improve traffic
security and welcome an upheaval on the driving experience. In any case, these benefits are balanced
conceivable assaults that undermine the vehicle's security, yet additionally travelers lives. One of the most
widely recognized ones is the Sybil assault, which is more risky than others since it could be the beginning
stage of numerous different assaults in VANETs. This paper proposes a dispersed methodology permitting
the discovery of Sybil at tacks utilizing the traffic flow hypothesis. The key thought here is that every vehicle
will screen its neighborhood so as to identify a possible Sybil assault. This is accomplished by contrasting
between the genuine precise speed of the vehicle and the one evaluated utilizing the V2V correspondences
with vehicles in the region. This evaluated speed is acquired utilizing the traffic flow principal chart of the
street's segment where the vehicles are moving.
A numerical model that assesses the pace of Sybil assault discovery air conditioning cording to the traffic
thickness is proposed. At that point, this model is approved through some broad re-enactments directed
utilizing the notable NS3 arrange test system together with SUMO traffic test system.

Enhanced Kalman Filter Navigation Algorithm Based on Correntropy and Fixed-Point Update
Authors: Pagoti Sirish Kumar , Vemuri Bala Sai Srilatha Indira Dutt , Mohiddin Mohammad Khaja
Published: February 2022

The accuracy of position estimation plays a key role in many of the precise positioning applications such as category I (CAT-I) aircraft landings, survey work, etc. To improve the accuracy of position estimation, a novel kinematic positioning algorithm designated as correntropy Kalman filter (CKF) is proposed in this study. Instead of minimum mean square error (MMSE), correntropy criterion (CC) is used as the optimality criterion of CKF. The prior estimates of the state and covariance matrix are computed in CKF and a novel fixed-point algorithm is then used to update the posterior estimates. The data of a dual-frequency global positioning system (GPS) receiver located at Indian Institute of Science (IISc), Bangalore (13.021°N/77.5°E) is collected from Scripps Orbit and Permanent Array Centre (SOPAC) to implement the proposed algorithm. The results of the proposed CKF algorithm are promising and exhibit significant improvement in position estimation compared to the conventional methods.
Lightweight Compressive Sensing for Joint Compression and Encryption of Sensor Data
Authors: Chatamoni Anil Kumar , Bhukya Rajendra Naik
Published: February 2022

The security and energy efficiency of resource-constrained distributed sensors are the major concerns in the Internet of Things (IoT) network. A novel lightweight compressive sensing (CS) method is proposed in this study for simultaneous compression and encryption of sensor data in IoT scenarios. The proposed method reduces the storage space and transmission cost and increases the IoT security, with joint compression and encryption of data by image sensors. In this proposed method, the cryptographic advantage of CS with a structurally random matrix (SRM) is considered. Block compressive sensing (BCS) with an SRM-based measurement matrix is performed to generate the compressed and primary encrypted data. To enhance security, a stream cipher-based pseudo-error vector is added to corrupt the compressed data, preventing the leakage of statistical information. The experimental results and comparative analyses show that the proposed scheme outperforms the conventional and state-of-art schemes in terms of reconstruction performance and encryption efficiency.
Evaluation on Mechanical Deterioration of the Asphalt Mixtures Containing Waste Materials When Exposed to Corrosion Solutions
Authors: Lukjan Arun , Iyaruk Arsit , Somboon Chumroon
Published: February 2022

This research investigates the effect of corrosion solutions on the mechanical properties of asphalt concrete mixtures. A control asphalt mixture (CM) and five polymer-modified (PM) or filler-modified (FM) mixtures containing waste materials are prepared, namely PM high-density polyethylene plastic (PM-PL), PM crumb rubber (PM-CR), FM Para wood ash (FM-PA), FM palm empty fruit bunch ash (FM-EA), and FM rice husk ash (FM-RA). The experiment is conducted by immersing the mixture specimens in four types of water solutions (i.e., distilled water, alkaline solution, sulfate solution, and acid solution), followed by the splitting tests. Finally, the corrosion resistance factor (fc) is computed to assess the corrosive effect of the corrosion solutions. The results show that the degree of reduction in tensile strength mainly depends on the type of corrosion solutions, type of mixtures, and immersion time. FM-EA provides better resistance under the alkaline and acid solutions, while PM-PL exhibits the greatest fc under the sulfate solution. Among all the mixtures, PM-PL shows the greatest ability in withstanding the corrosion solutions.
Sobre ciertos elementos de déficit democrático en el seno del Consejo de Europa
Authors: Belorgey Jean-Michel
Published: February 2022

El autor expresa en el artículo su inquietud por las tendencias que, en el curso de los últimos años, han llevado al Consejo de Europa a no guardar coherencia en su propio funcionamiento con los tres pilares sobre los que se asienta la Organización (derechos humanos, democracia y Estado de Derecho). En este sentido, en la primera parte el autor relaciona esa preocupación con un exceso de burocratización y una inconsistencia con el respeto del imperio de la ley en los procedimientos internos. A continuación, la segunda parte ilustra dicha preocupación con episodios lamentables (referentes a la modificación del reglamento interno o a la elección de los órganos representativos) en los que se ha visto implicada la Conferencia de las OING en el seno del Consejo de Europa. En fin, el autor reflexiona sobre la necesidad de reforzar los pilares del Consejo de Europa reduciendo el déficit democrático en su funcionamiento interno.

Sin embargo, en el ámbito nacional, los antecedentes fueron más variados en cuanto a la falta de eficacia de la Carta debido al rechazo de su justiciabilidad. En los últimos años, la suerte de la Carta ha mejorado gracias al reconocimiento de su efecto directo por parte de los jueces franceses. Sin embargo, como este reconocimiento es sólo parcial y persisten algunas incoherencias de la legislación francesa con la Carta, todavía hay margen de progreso.

Watch for the Ripples, Not Just the Splash: How the EU Position on Investment Arbitration Has Affected the Enforcement of Awards
Authors: Kovács Bálint
Published: February 2022

The European Commission’s attempts to end intra-European Union (EU) investment arbitration, and the decisively helping hand lent by the Court of Justice of the European Union (CJEU) have produced massive splashes, rightfully attracting much attention. However, the ripples after the several splashes have had limited effects. This paper briefly outlines the splashes and goes on to analyze the ripples: investment tribunals retaining jurisdiction and issues around recognition and enforcement within and outside the EU. Although the judgments of the CJEU have had limited effects outside the EU, they have made it more difficult to enforce intra-EU awards within the EU and sometimes also outside of it. The study also examines some of the tools used by the EU to effectively shut the door on intra-EU investment arbitration, which mostly burden its Member States, such as infringement proceedings and decisions on unlawful state aid.

On 24 September 2016, a terrorist act, which had never happened before in Hungary, was committed in Budapest. The perpetrator wanted to kill two police officers on duty in a premeditated bombing. The study presents one element of forensic thinking, the thinking in versions, based on the assassination attempt that came to be known as the Teréz Boulevard bombing. In addition to describing the material facts of the crime and the main investigative measures, the author places the main emphasis on the versions set up during the investigation and shows what roles each version played in the investigation.
Áldozatból bűnös? Bűnösből áldozat? A Simek Kitty-ügy tanulságai húsz év távlatából
Authors: Szabó András
Published: February 2022

The case of Simek Kitty garnered a lot of interest in the media between 2002 and 2005. The fourteen-year-old girl, who endured her stepfather’s physical, verbal, and sexual abuse for ten years, one day shot the aggressive man with his own weapon. Although the court sentenced the young girl for her deed, the President of the Republic gave her amnesty, so she did not have to go to jail after all. However, her life turned even worse after the incident. In my study, I examine why the events turned out the way they did and how the tragedy could have been avoided.

"Entre Primos(as)"
Authors: Monteiro Edilma
Published: February 2022

A escolha por nomear esse ensaio fotográfico, ‘ENTRE PRIMOS(AS)’: Vivências cotidianas entre ciganos Calon está assentado numa indicação êmica. O termo ‘primo’ é uma expressão utilizada entre os ciganos da etnia calon para denominar outra pessoa cigana, e não necessariamente define uma relação de parentesco. O ‘primo (a)’ é, neste sentido, colocado como categoria para reconhecer uma pessoa calon ou muito próxima ou  pertencente a uma rede familiar. Tal dado foi compreendido a partir do envolvimento nos contextos etnográficos.  Assim, o termo primo é utilizado para relações com base de aproximação e afetividade, deve ser pensado como uma nomeação que integra o cotidiano dos ciganos Calon no Brasil, (MONTEIRO, 2019). Mas quem são essas pessoas ciganas que veremos nestas imagens?

Evaluación del interés del uso de una cubierta vegetal bajo la línea como estrategia de gestión del suelo en viñedos cultivados en condiciones de clima mediterráneo
Authors:   , Abad Zamora Francisco Javier
Published: February 2022

El manejo del suelo de los viñedos en condiciones de clima mediterráneo siempre ha primado reducir la competencia que pudieran generar otras plantas por los recursos nutricionales y, en especial, por los recursos hídricos. Sin embargo, los cambios de sistemas de producción, con desplazamiento de los viñedos a terrenos más fértiles, muchas veces dotadas de riego; la necesidad de buscar alternativas a los herbicidas como elementos de control de la vegetación adventicia, en especial en la zona ubicada bajo las cepas; plantean la posibilidad, o incluso la necesidad, de trabajar el suelo de manera diferente. En los últimos años, se ha avanzado de manera relevante en el estudio de las implicaciones del introducir las cubiertas vegetales como alternativa al uso de herbicidas y al laboreo, habiendo quedado de manifiesto el interés agronómico y ambiental de este cambio de manejo, que, como cualquier otro, debe acometerse considerando todas sus implicaciones en función de las particularidades de cada viñedo y objetivo agronómico-empresarial. Sin embargo, la práctica totalidad de las actuaciones encaminadas a introducir el uso de cubiertas en viñedos de zonas mediterráneas implican un cambio de gestión del suelo las calles, pero no del suelo bajo la línea de cultivo. En este contexto, la posibilidad de emplear una cubierta vegetal bajo la línea de cultivo que permitiera competir con otras adventicias pero no lo hiciera de manera relevante con el viñedo podría ser una alternativa de mucho interés. En esta Tesis Doctoral se ha estudiado el comportamiento de una cubierta de T. fragiferum (UV) frente a un manejo con laboreo intercepas (T). Dicho ensayo se realizó durante tres campañas consecutivas (2018, 2019 y 2020) en un viñedo de Merlot ubicado en terrenos de Bodegas Ochoa en Traibuenas (Navarra-España), sobre un suelo Typic Calcixerepts y con un clima húmedo-templado mediterráneo según la clasificación de Papadakis. El conjunto de los resultados obtenidos permite concluir que el empleo de una cubierta de T. fragiferum bajo la línea de cultivo del viñedo en condiciones de clima mediterráneo constituye una alternativa realista al uso de herbicidas o laboreos intercepas. En las condiciones de ensayo, su uso ha redundado en una mejoría notable de los parámetros de calidad del suelo, sin apenas alterar el comportamiento agronómico y enológico de las cepas, resultando económicamente viable cuando se consigue una supervivencia de la cubierta mínima de tres años.
“SIX THINKING CARDS”: A GAME FOCUSED ON DEVELOPING ARGUMENTATIVE SKILLS IN THE CHEMISTRY CLASSROOM
Authors: PASSINATO Cristiana de Barcellos , DE OLIVEIRA Victória Beatriz dos Santos , DE ALMEIDA Luciana Pereira
Published: February 2022

Considering the increasing need to develop the argumentation and communication skills of the students, teaching practice has to consider how to do this concerning individual needs and preferences. Meaningful Learning proposes that education should consider the already acquired knowledge of the students in the process of building new learning. Therefore, when applied to the learning process, argumentation is a way to express acquired knowledge to other participants of this process. The Six Thinking Cards game permits students to explore their thinking in focused stages that are represented by the colors proposed in the Six Thinking Hats strategy by Edward De Bono, thus creating an environment where students have time and space to study and think about scientific concepts in a throughway. It is expected that the game also helps students develop soft skills that are considered essential for 21st century learning, such as empathy, communication, problem-solving, and teamwork. The game also adds Libras (Brazilian Sign Language) and Braille (tactile writing system) elements for accessibility purposes towards the objective of building an inclusive classroom. This game should be able to be applied in the chemistry classroom once Covid-19 hard restrictions and quarantine are over and in-person studies are permitted, allowing the authors to do qualitative and quantitative research of this proposal’s reach and relevance for beyond of the projection of this proposal. Interviews with both teachers and students are to understand better how students’ metacognitive skills improve as they engage in cooperative learning and express their ideas.
