O papel da violência escolar no abandono da carreira docente: proposta de uma matriz analítica
Authors: Garcia-Silva Sullyvan , Lima Junior Paulo
Published: March 2022

Resumo A violência escolar é tema de pesquisa no Brasil desde os anos 1980 e está entre os principais desafios enfrentados pela educação no país. O objetivo central deste artigo é discutir o papel das experiências de violência escolar no abandono da carreira docente. Para isso, entrevistamos uma ex-professora que, assim como muitas outras, abandonou a docência após sofrer exaustão emocional em decorrência das violências sofridas na escola. A partir da literatura e da investigação narrativa dos relatos da ex-docente, consideramos importante reconhecer que a violência escolar é uma experiência objetivamente regulada e subjetivamente vivida. Enquanto realidade objetivamente regulada, a violência pode ser classificada como crime, incivilidade e violência simbólica. Como experiência subjetivamente vivida, podemos distinguir diferentes graus de banalização que, no sentido empregado por Arendt, designa a superfluidade e a superficialidade das relações humanas em sistemas totalitários. Juntas, as duas dimensões, objetiva e subjetiva, formam o que denominamos matriz da violência escolar, uma ferramenta analítica potencialmente útil para investigar como a violência influencia os percursos profissionais docentes. Os resultados ainda permitiram entender como os diversos agentes escolares (alunos, diretor e a própria professora) participam da produção da violência escolar e como as partes envolvidas têm percepções conflitantes. Por fim, implicações na formação de professores são discutidas.
Using digital image processing and Unmanned Aerial Vehicle (UAV) for identifying ceramic cladding detachment in building facades
Authors: Sousa Alcineide Dutra Pessoa de , Sousa Gean Carlos Lopes de , Maués Luiz Maurício Furtado
Published: March 2022

Abstract Facade maintenance actions are driven by results obtained in the inspection phase. Some methodological proposals aimedat optimizing the inspection process have been discussed, notablydigital image processing (DIP) techniques associated with unmanned aerial vehicle (UAV) imagery. Using UAV speeds up the access to the inspected area, and DIP techniques help to automate the identification of pathological manifestations. This article aims to apply DIP techniques to detect areas where the ceramic cladding on building facades is detaching. The methodology referred to herein starts with the creation of a database (images) captured by cell phone and UAV. The object detection algorithm YOLO (You Only Look Once) was applied to the database images. The results indicated these techniques are very promising, with a 94% precision level in the tests performed. The precision index obtained indicates that the model is applicable in practice and discussions about its limitationshelp improve the proposed methodology.

Coloniality and its Future
Authors: Anzi Achia
Published: March 2022

Decoloniality emerged in the last two decades as a new mode of critique against colonialism and coloniality. While its insights are inspired by dependency and postcolonial theories, decoloniality challenges them both, particularly their inability to depart with modern Western epistemology. Written in response to Arjun Appadurai's recent critique of On Decoloniality by Catherine E. Walsh and Walter D. Mignolo, this article attempts to articulate decoloniality's approach to epistemology and discourse analysis. Whereas Appadurai describes Walsh and Mignolo's position as an anachronistic attempt to "return to the precolonial past," this article underlines his inability to transcend the modern linear order of time.
The Subject as Migrant: Refiguring the Migrant Image in the Eastern Cape
Authors: Steele Candice , Minkley Gary
Published: March 2022

This paper engages with the concept of the migrant subject, as framed through contemporary literature on migrancy, and read through the Pauline Ingle photographic collection, located in the Eastern Cape. As against gendered historiographies of labour migrancy and the associated meanings attributed to the rural as a site of social reproduction, Ingle's photographs invite a series of atypical readings that unsettle these subjectivities. Rather, they suggest social and political acts that presage and constitute a migrant citizenship, one that undermines the dichotomy of the rural (traditional) and urban (modern) and projects the possibility of reading the history of the subject in the Eastern Cape differently.

Published: March 2022

As a result of the depletion of high-grade manganese reserves, it has become necessary to consider the exploitation of low-grade manganese ores. The main problem of low-grade manganese ore is the low Mn/Fe ratio, which makes it unfit for the production of manganese ferroalloys. In this work, a selective reduction technique was used for smelting low-manganese ore in the presence of coke and fluxing material in an electric submerged arc furnace to obtain a rich manganese slag and low-manganese pig iron. The product slag was blended with medium-manganese ore and smelted in an electric submerged arc furnace, in the presence of coke and the fluxing agent, to produce silicomanganese alloy. The influence of reducing agent ratio, charge basicity, and charge Mn/Si ratio on the smelting process was investigated. The optimum conditions were found to be a coke ratio of, 1.35, Mn/Si ratio of 2.0, and charge basicity of 2.5. The silicomanganese alloy produced under these conditions satisfies the specifications for Si16Mn63 and Si17Mn65. The experimental results were applied on a pilot scale, producing a silicomanganese alloy with a chemical composition close to that of the standard specifications.

Authors: Hassouneh Stephanie , Ablah Elizabeth , Okut Hayrettin , Harrison Mark
Published: March 2022

Introduction. By 2050, more than 580,000 children in the United States will be diagnosed with type 1 diabetes (T1D). Management of T1D requires careful and continuous intervention, and children with T1D experience greater challenges in disease management than their adult counterparts. Diabetes camps are designed to help those with T1D learn diabetes management skills while experiencing summer camp. Psychological aspects are not explicitly addressed in diabetes camps located in Kansas. The purpose of this study was to evaluate the psychological state of past campers and camp counselors from one diabetes camp in Kansas.Methods. Campers and counselors who had T1D and attended diabetes camp from 2015 to 2019 in Kansas were recruited to complete a survey about diabetes-related stress, diabetes management self-efficacy, and symptoms of depression. A link to the online survey was distributed to previous campers and counselors by email and through Facebook.Results. A total of 24 camp counselors and 10 campers were surveyed, 100% of whom reported having T1D and attending camp at least once. One-third of respondents (n=8) reported having severe diabetes-related stress, and 100% (n=34) reported high levels of diabetes management self-efficacy. Most participants reported moderate levels of depression, and 9% (n=3) reported a past suicide attempt. These results suggest a relatively high prevalence in signs of psychological distress from former campers and camp counselors with T1D.Conclusions. This study suggests that campers and counselors with T1D have high levels of diabetes-related stress, high diabetes management self-efficacy, and many signs of depression.
Are investments in natural infrastructure cost-effective? A contextual analysis of payments for hydric ecosystem services
Authors: Cervantes Ronal , Sánchez José , Rendón Eric , Alegre Julio
Published: March 2022

The growing deterioration of water ecosystem services as the lack of budgetary resources for their recovery and management as well, are a global concern. This forces to prioritize the most appropriate measure among a range of possibilities. The economic evaluation of cost-effectiveness is one of the technical alternatives indicated by this value judgment. This study seeks to know if investments in natural infrastructure, dictated by the Peruvian State, are cost-effective in a scenario of payment for watershed ecosystem services, implemented in the Mariño river basin. To do this, the incremental cost-effectiveness ratio of four water regulation strategies was compared, then it was evaluated with the cost-effectiveness threshold that was established according to the willingness to pay of the population of Abancay. The evaluation indicates that a natural infrastructure project that promotes the active recovery of ecosystem services is not profitable since its cost-effectiveness ratio (0.35 PEN or 0.091 USD/m3 of water) exceeds the cost-effectiveness threshold (0.20 PEN or 0.052 USD/m3 of water). The results offer relevant elements to choose investment alternatives in a context of budget constraint.

Published: March 2022

Liturgusa Maya is a cryptic species that travels on cacao and citrus stems. The objective of this study was to determine some aspects of their biology and behavior and to identify ootheca parasitoids. Nymphs and adults were collected in the cocoa stems to obtain ootheques and determine the incubation period and the number of individuals per ootheca, ootheca were also collected to determine the presence of parasitoids. Incubation fluctuates between 15 and 17 days and individuals per ootheca between 23 and 37. The adult female stage measures an average of 25.30 mm in length and the male 20.38. Three species of parasitoids were recovered from the ootheques collected in the field: Podagrion sp., Eupelmus sp., and Horismenus sp., belonging to the families Torymidae, Eupelmidae and Eulophidae, the most important species belongs to the genus Horismenus. The present study seeks to establish the interactions that L. maya fulfills in the cacao agroecosystem and to define if its presence is related to the management of organic crops.

Published: March 2022

This protocol was designed to enhance signal for backscatter electron imaging of epoxy embedded mammalian tissue at low accelerating voltages (1-3 keV). However, it can easily be adapted for use with tissues from other species, tissue culture cells, plants and microbial cells by adjusting the buffer strength and the duration of relevant steps. This combinatorial heavy metal staining protocol employs a battery of contrasting steps after primary aldehyde fixation including: ferrocyanide reduced osmium tetroxide post fixation, thiocarbohydrazide-osmium liganding (OTO) and subsequent uranyl acetate and en bloc lead aspartate staining. Calcium chloride is included in a number of steps to enhance membrane preservation and staining. This protocol was designed primarily to emphasize the contrast of membranes. Many other contrasting agents may be included to increase staining of other cellular and extracellular constituents.

Representations of Epistemological Colonization
Authors: Szűcs Teri
Published: March 2022

It can be argued that apart from critically applying the theoretical framework of Postcolonial Studies to Romani Studies, we can effectively describe the position and the history of the European Roma by applying some of the insights of Indigenous Studies. Dipesh Chakrabarty’s conception of “heterotemporality” may play an important role in the dialogue between postcolonial and indigenous theories, addressing temporal plurality of coexistent cultures. In my paper I argue that the hierarchy of powerful and weak narratives is always inscribed into the heterogeneity of historiographies – that is, the plurality of heterotemporal narratives is always inherently hierarchical, being a political construction. I am discussing Béla Osztojkán’s There is Nobody to Pay Jóska Átyin, the magnificent Hungarian Romani historical novel published in 1997, to trace the representations of epistemological oppression, to explore how the colonized, the Romani subaltern is taking part in the discourse of heterotemporality, and finally to see how the fragmented – “different” – historical knowledge is created and articulated in a literary work.
Stereotyping and Stigmatizing IT professionals Toward a model of devaluation
Authors:   Baylor University, Moquin René , Rutner Paige ,   Texas Tech University, Giddens Laurie ,   Southern Illinois University Edwardsville
Published: March 2022

An understanding between information technology (IT) and business units is important to information systems research in that their alignment is critical for organizational performance in the digital environment. Negative perceptions and associated behavioral outcomes can affect group cohesion and effectiveness. The present research uses the lens of stigma and stereotypes to explore a notion of non-productive relationships between the IT and nonIT groups. The primary focus of this study was to analyze interviews with IT professionals to explore and identify potential antecedents to stigma. The differences between IT professionals and users are defined and explicated, illustrating the occurrence of stereotyping among and between the various groups. We found that relationships between the IT and nonIT groups appear to support a notion of differentness. The support of stigmatization between these two groups likely exists in interpersonal relationships during situations of stress, cultural differences, and expectations. Relationships in the pervasive digital environment between business units are critical for organizational performance. Each unit maintains its own culture and, therefore, the associated views and behavioral outcomes. The existence of different groups implies a difference in perception, expectation, and ultimately performance.
Risk and Demographics’ Influence on Security Behavior Intentions
Authors:   University of Massachusetts Boston, Ayyagari Ramakrishna
Published: March 2022

Behavioral information security has become an important aspect of information security. In this study, we extend previous works on developing a comprehensive tool to measure security behaviors (i.e. Security Behavior Intentions scale - SeBIS(Egelman & Peer, 2015)). We extend the work on SeBIS by 1) proposing the use of security domain-specific risk as opposed to a generic risk measure, 2) investigating differences in SeBIS across age, gender, education and experience, and 3) providing suggestions for improving SeBIS measures. Survey results from our study provide support for security risk - device securement relationship, a previously unsupported link. We also uncover the role of demographics in influencing SeBIS. Overall, our study contributes to, and further establishes SeBIS as a predictive tool for measuring security behaviors.
Psychological Contract in IT: A Qualitative Exploration of Missed Expectations
Authors:   Northeastern State University, Moquin René
Published: March 2022

This study examines the nature of reciprocity between IT workers and their organization and the IT profession by applying two theoretical perspectives - social identity and the psychological contract. Social Identity Theory addresses the connection between individuals and their profession while Psychological Contract Theory addresses the mental retention of direct and indirect promises and their reciprocation. The linkage of these theories assesses the behavioral outcomes of missed expectations. The results from in-depth interviews with IT professionals generate a taxonomy of twenty-five themes that potentially influence a breach or violation of the psychological contract. The discussion then focuses on the four salient themes that were highly referenced by the interviewees and that closely aligned with the theoretical foundations of the study. This paper widens the operational aspects of the Psychological Contract by investigating the factors that potentially influence a Psychological Contract Breach and Psychological Contract Violation within the IT profession.
Organic Barley and Wheat Production Forecast: The Case of Ağrı Province
Authors: ŞAHİN DEMİREL Ayça Nur
Published: March 2022

This study explains the trend analysis for organic wheat and barley production in Turkey-Ağrı province between 2021 and 2024. For organic product production, the organic agricultural farm area trend and the organic agricultural worker trend have been analyzed. Until 2015, it has been determined that there was an increase in the number of organic agricultural areas and workers, but between 2015 and 2020 the trend of stagnation and then the downtrend had been occurred. While a similar trend has occurred in organic wheat production, it has been determined that organic barley production has been increasing overall since 2008. For the estimations of 2021-2024 years in the organic farming area, number of workers, wheat and barley production in Ağrı province, the Exponential Growth Method was applied separately to the 2007-2020 data with the Quadratic Trend Analysis method and ideal estimation data were tried to be obtained. Within the scope of the forecast results obtained, organic barley production is expected to be on an upward trend in the coming years, while organic wheat production is expected to be the opposite. In the light of these analysis results, it is of great importance for agricultural producers to raise awareness of producers and turn the downward trends back into an upward trend.

In this paper, hyperbolic spinor representations of space curves are studied according to the q-frame in E_1^3. The spinor formulations of curves are calculated for the q-frame according to the spacelike and timelike tangent vector cases of the curves in E_1^3. Moreover, the relationships of spinor equations between q-frame and Frenet frame in Lorentz space are expressed. The results are supported with some theorems.
Kükürt Bazlı Miksotrofik Denitrifikasyon Prosesinde Azot/Fosfor (A/F) Oranının Nitrat Giderimine Etkisi
Authors: ÖZTÜRK Arzu
Published: March 2022

Tüm dünyada olduğu gibi Türkiye’de de tarımsal sulama, yoğun gübreleme, atıksuların uygunsuz deşarjı gibi nedenlerle sularda nitratın arttığı görülmektedir. Sağlığa zararları nedeniyle nitratın giderimi için pek çok arıtma teknolojileri geliştirilmiştir. Bu çalışmada mevcut nitrat giderim yöntemlerine alternatif, etkin ve avantajlı bir yöntem olan miksotrofik denitrifikasyon kullanılmıştır. Bu yöntem ototrofik ve heterotrofik denitrifikasyonun birlikte kullanılması esasına dayanır. Bu nedenle miksotrofik denitrifikasyonu etkileyen elektron verici kaynağı, karbon/azot (K/A) oranı, azot/fosfor (A/F) oranı, sıcaklık, Hidrolik Bekleme Süresi (HBS), pH, alkalinite, girişte verilen organik maddenin cinsi gibi pek çok parametre bulunmaktadır. Bu çalışma ile miksotrofik denitrifikasyonun etkin bir şekilde gerçekleşmesi için gerekli optimum A/F oranının tespit edilmesi amaçlanmıştır. Bu amaçla kurulan laboratuvar ölçekli kolon reaktörlerde elektron vericinin kükürt ve metanol, elektron alıcının nitrat olduğu bir sistem kurulmuştur. Literatür incelenerek 5/1, 5/0.5, 5/0.25, 5/0.1 A/F oranları seçilmiş ve bu oranlarda reaktörler işletilmiştir. İşletme koşullarının belirlenmesinde motivasyon, besine eklenecek fosfat miktarı için optimum miksotrofik koşulları sağlayacak minumum miktarın tespiti olmuştur. Reaktör sıcaklığının 20±5 C0 olduğu koşullarda miksotrofik denitrifikasyonun ÇOK/NO3-N 0.66 oranında gerçekleştiği bulunurken, optimum A/F oranın 5/0.5 olarak bulunmuştur. Böylece hem ÇOK/NO3-N oranı hem de A/F oranı literatürde bildirilen değerlerden daha düşük olduğu halde miksotrofik denitrifikasyonun başarılı bir şekilde gerçekleştiği görülmüştür.

Metropol kentlerde yüksek katlı binalar veya rezidansların kış aylarında Zemin altı otoparklarının giriş ve çıkış alanlarında oluşan kar veya buz nedeniyle araçların otoparka giriş ve çıkışları neredeyse imkansızdır. Bir yol yüzeyindeki kaygan koşulları azaltmak için kimyasal tuz veya kar küreme gibi mekanik olan bazı konveksiyonel yöntemler kullanılmaktadır. Bu yöntemlerin gerek yol altyapılarına gerekse çevresel sorunlara neden olduğundan temiz ve alternatif bir yöntem olan Hidronik Isıtmalı Kaplama (HHP) yönteminin kullanması ön plana çıkmaktadır. HHP yöntemi araçların geçtiği yolun altına yerleştirilmiş ve içinden sıcak akışkan geçen borulardan oluşmaktadır. Bu çalışmada, Zemin altı otopark giriş ve çıkış yollarında oluşacak kar veya buzu önlemek amacıyla HHP sistemi için yeni bir model geliştirilmiştir. Ancak bu yeni önerilen uygulamanın özgünlüğü, ısı kaynağı olarak kazan veya ısı pompası gibi ek bir ısıtma sistemi uygulamak yerine binanın merkezi ısıtma sisteminden faydalanılmasıdır. Zemin otopark giriş ve çıkış alanının altına PEX boruları yerleştirilerek hidronik olarak araç yolunun ısıtılması ve MATLAB’ta geliştirilen yeni bir kod sayesinde meteorolojik verileri kullanarak zamana bağlı üç boyutlu olarak simüle edilmiştir. Zemin otopark giriş ve çıkış yollarında buz ve kar oluşmaması için borular arası mesafe, gömme derinliği, hava sıcaklığı ve akışkan giriş sıcaklığının etkileri incelenmiştir. Ek olarak, farklı hava sıcaklıklarına göre hidronik ısıtma borularının yerleşiminin ve akışkan giriş sıcaklığının optimizasyonu gerçekleştirilmiştir.

Published: March 2022

The impact of lattice frequency on the defect lattice solitons have been investigated in a medium with quadratic nonlinear response. Governing equation of the optical system has been formed by adding an external lattice to the NLSM system, and soliton solutions of the system were calculated by the squared operator method. Moreover, stability of the fundamental solitons have been examined by the linear stability spectra and nonlinear evolution of the solitons. It has been demonstrated that although higher lattice frequency extends the existence domain of defective lattice solitons in a quadratic nonlinear medium, it negatively effects the stability dynamics of the solitons.

EN 197-1 standardına göre üretilen çimentoların dayanım sınıfları EN 196-1 standardına göre belirlenmektedir. EN 196-1 standardına göre yapılan çimento harcı üretimlerinde üretim tekniği olarak kaba önce su konulur, daha sonra çimento eklenerek 30 s düşük hızda çalıştırılır, sonraki 30 s sürede kum ilavesi yapılır, karıştırıcı 30 s yüksek hızda çalıştırılır, 90 s sonra cihaz durdurularak kabın içerisine yapışan harç temizlenerek karışıma ilave edilir ve üretime 60 s yüksek hızda devam edilerek üretim süreci tamamlanır. Üretim standardı belirlenmeyen harçların üretimlerinde ise homojenliği sağlamak üzere çoğunlukla önce kuru karışım (çimento-kum veya çimento-agrega), daha sora ise kuru karışıma gerekli su ilavesi yapılarak karışımın mümkün olduğunca homojenleştirilmesi sağlanmaktadır. EN 196-1 de belirtilen üretim tekniği ile diğer alternatif üretim tekniklerinin karşılaştırılması amacıyla yapılan bu çalışmada; 3 farklı firmadan temin edilen CEM I 42.5 R tipi çimento, kum ve suyun karışıma girme sıraları değiştirilerek ve EN 196-1 standardında belirtilen süreçler baz alınarak 6 farklı üretim tekniğine göre üretimler yapılmıştır. Üretilen örneklerin EN 1015-3 standardına göre yayılma değerleri, EN 12350-6 standardına göre taze yoğunluğu, EN 196-1 standardına göre 2, 7 ve 28 günlük dayanım özellikleri, EN 12390-7 standardına göre sertleşmiş yoğunluğu, Arşimet prensibine göre su emme yüzdeleri ve porozite değerleri ile EN 1015-18 standardına göre kılcal su emme katsayısı değerleri belirlenmiştir. Çalışmanın sonucunda işlenebilirlik açısından en uygun üretim tekniğinin kum-su-çimento sıralaması ile üretilen örneklerde olduğu, mekanik özellikler açısından ise en uygun üretim tekniğinin ise EN 196-1 standardında belirtilen üretim tekniği olduğu sonucuna varılmıştır.

Cerebral palsy is a group of developmental disorders affecting motor skills and postural maintenance, leading to motion defects due to non-progressive damage and/or a developing brain anomaly in the fetus or the newborn child. Leg muscle weakness and spasticity associated with cerebral palsy limit the range of motion in the ankle joint and negatively affect the childs motor ability. This article reviews scientific studies on an innovative method of functional electrical stimulation of walking in children with cerebral palsy. We searched for information in the Scopus, Web of Science, Medline, The Cochrane Library, PubMed, Pedro, Scholar, eLibrary, and CyberLeninka databases. The efficiency of remedial treatment of motion using functional electrical stimulators was assessed using biomechanical and neurophysiological methods of evidence-based medicine. When children are rehabilitated using electrical stimulation techniques such as functional electrical stimulation, the gait is restored significantly, dorsiflexion is improved, the gait pattern is normalized, stability when walking is increased, the number of falls is decreased, and the need for additional support is reduced. The effect of functional electrical stimulation on the normalization of walking speed, gait kinematics and symmetry, the ability to overcome obstacles, and the range of motion of the ankle joint and foot clearance during walking are discussed. In addition, the work analyzes the effect of functional electrical stimulation on reducing the patients energy consumption when walking, normalizing muscle tone, decreasing the risk of falls, and increasing confidence and comfort when walking. As part of this analysis, the speed of adaptation and patient tolerance of the devices for functional electrical stimulation are also discussed. A comparative characteristic of functional electrical stimulation using ankle joint orthoses is provided.
CONCLUSIONS: For many years, movement dynamics have used functional electrical stimulation technologies to rehabilitate neurological patients after stroke and multiple sclerosis. It is only a matter of time before these technologies also become the standard treatment for children with cerebral palsy in rehabilitation programs.

This study focuses on the clinical symptoms of inflammatory and destructive lesions of the facial skeletal bones as a long-term complication of coronavirus disease-2019 (COVID-19). The most common symptom of COVID-19 is thrombosis. Many scientists have noted that the main target of COVID-19 is the lungs with varying damage severity in the form of pneumonia. Acute cerebrovascular accidents and coronary pathology have become the most common causes of lethal outcomes in young people. Clinically, in patients with COVID-19, both obvious thrombotic complications were recorded with large thrombi detection (not only in the veins and pulmonary arteries, but also in the heart and vessels of the brain, kidneys, and liver), as well as signs of thrombosis at the microcirculatory level, which is quite difficult to establish in vivo. The diagnostics, treatment, and follow-up of a patient with COVID-19 history and complications that arose in the maxillofacial region were conducted in the Department of Maxillofacial Surgery of Clinical Hospital. Upon admission, the patient was diagnosed with chronic osteomyelitis of the upper jaw on the right, chronic right-sided maxilloethmoidal sinusitis, mucous membrane defect on the right hard palate, oroantral fistula on the right, and keratitis of the right eye. During the inpatient treatment, multicomponent therapy was performed. During the therapy, a general condition and local status improvement of the patient was noted.
CONCLUSIONS: The clinical cases indicate that the course of COVID-19 is characterized by late complications in the maxillofacial region in the form of damaged vessels that extend from the а. maxillaris trunk in the pterygopalatine fossa region.
The trophic disorder was slowly progressive and irreversible. The clinical and radiological presentation showed no clearly defined boundaries of bone necrosis of the facial middle zone. Low tissue regeneration was noteworthy.
