Authors: Villar Varela Milena , Méndez-Lois María José , Barreiro Fernández Felicidad
Published: December 2021

Introducción.  Los dispositivos inteligentes han llegado para quedarse, convirtiéndose en el medio de socialización por excelencia, en el instrumento fundamental en la adolescencia para comunicarse y relacionarse con el mundo. Si bien es cierto que este tipo de dispositivos ofrecen innumerables ventajas, es necesario ser conscientes de que entrañan riesgos y amenazas si no se emplean de manera adecuada.  Uno de estos peligros es la transmisión de la desigualdad de género reforzando las estructuras sociales y culturales vigentes y provocando nuevos tipos de violencia patriarcal. Este estudio pretende conocer las conductas de violencia de género ejercidas por los y las adolescentes en entornos virtuales y comprobar si existen diferencias significativas en función de las variables sexo y curso.
Método. Se llevó a cabo un estudio ex post facto descriptivo de corte transversal en el que participaron 615 adolescentes con edades comprendidas entre los 14 y los 18 años. El instrumento utilizado en la investigación fue un cuestionario elaborado ad hoc para el estudio. 
Resultados.  Los resultados muestran que las conductas de violencia de género en entornos virtuales son realizadas en mayor medida por los varones, excepto aquellas conductas relacionadas con los mitos del amor romántico, una de las tipologías de violencia de género reconocida por las personas expertas en el ámbito, que son llevadas a cabo mayoritariamente por mujeres. También se observa que este tipo de conductas son más realizadas por el alumnado de 4º curso de ESO.
Discusión y conclusiones.  Los resultados de este estudio ponen en evidencia la necesidad de llevar a cabo intervenciones educativas que permitan prevenir la violencia de género en entornos virtuales, así como diseñar medidas de tratamiento debido, sobre todo, a los efectos perjudiciales de este tipo de conductas en la adolescencia.

Authors: Holden Sinead , Matthews Mark , Rathleff Michael Skovdal , Kasza Jessica ,   Fohx Group, Vicenzino Bill
Published: December 2021

Objective

To determine whether the effect of hip exercise on patellofemoral pain is mediated through changes in hip muscle strength or psychological factors.

Design

Secondary mediation analysis of a randomized clinical trial, in which 218 participants with patellofemoral pain were randomly assigned to receive foot orthoses or hip exercises.

Methods

Pain (Knee injury and Osteoarthritis Outcome Score pain subscale) and number of pain-free squats at 12 weeks were the outcomes for this mediation analysis, as they are pathognomonic of patellofemoral pain. Hip strength dynamometry (abduction, adduction, and external rotation) and psychological characteristics (pain catastrophizing, kinesiophobia, and anxiety) measured at 6 weeks were considered as potential mediators. We used mediation analysis to decompose the total effect of treatment on the outcome into (1) the “indirect effect” (ie, the portion acting through the mediator) and (2) the “direct effect.”

Results

The effect of hip exercise on pain and squats was not mediated by any of the strength or psychological mediators analyzed. All indirect effects were small and showed wide 95% confidence intervals (CIs) that contained zero (eg, for pain-free squats: abduction strength, −0.13; 95% CI: −0.49, 0.23; Tampa Scale of Kinesiophobia, −0.17; 95% CI: −0.64, 0.30).

Conclusion

Hip strength improved after hip exercise, yet strength did not mediate improvements in pain and pain-free squats, and alternative psychological mediators were not implicated. J Orthop Sports Phys Ther 2021;51(12):602–610. doi:10.2519/jospt.2021.10674
Vindication of Real Estate: The Stage of Building a General Vindication Model for the Protection of Violated Absolute Rights
Authors: Murzin D. V.
Published: November 2021

The article considers the legal structure of vindication of real estate developed in Russian science and practice. Protection of the rights of the owner of real estate who has lost possession and is not registered in the Unified State Register of Real Estate (EGRN) is carried out by filing two lawsuits in court: for recognition of the right of ownership and vindication. Due to the peculiarities of the statute of limitations, in Russian practice, the priority of actual ownership of real estate over the records of ownership in the Unified State Register of Legal Entities is established. The need to combine the two claims is caused by their possible competition in connection with the application to each claim of its own rules on the validity of the statute of limitations. The refusal to extend the limitation period to the vindication claim for the return of ownership should lead to the establishment of only one claim within the framework of the method of protecting the violated rights of the owner to real estate – vindication. An independent claim for recognition of the right in this situation seems redundant. Its necessity is caused by an attempt to apply the German model of protection of the violated rights of the owner of real estate, where the impossibility of vindication is due to the high level of public reliability of entries in the register. In modern Russia, the position of complete denial of vindication of real estate is not supported by the consistent implementation of the principle of irrevocability of rights registered in state registers. At the same time, the construction of a claim for the protection of the rights of the owner of real estate allows us to take the first step towards the development of a vindication model for the protection of any absolute right, the elements of which are the requirement to recognize the right and the requirement to restore the legitimation of the right holder.
Law Enforcement Practice in Criminal Cases of a Crime under Art. 171.3 of the Criminal Code of the Russian Federation (In Terms of Establishing the Sign “Large Size”)
Authors: Karpenko N. A.
Published: November 2021

The article is devoted to problematic issues that arise in the practical activities of law enforcement agencies in terms of determining the cost of calculating a large amount of alcohol turnover, which significantly affects the qualification of a criminal act under Art. 171.3 of the Criminal Code of the Russian Federation. The emphasis is placed on the absence in law enforcement forensic practice of a single mechanism for determining the cost of a large size and the need to develop a single calculation algorithm for determining a large size taking into account criminal and criminal procedure legislation indicating the intent of a person to sell alcohol products in order to generate income. It was proposed to add to the current criminal legislation, which defines a common understanding of large-scale calculation.

The studies were carried out in 2020 at the "Berezanskoye" agricultural enterprise located in the Korenovsky district of the Krasnodar region. The aim of the research was to establish the possibility of improving the sowing qualities and yielding properties of the forming F1 seeds in the hybridization plot of a simple interline hybrid of sunflower Fakel. We studied the influence of various complexes of agrotechnical methods on plants of the maternal form of sunflower: application of the fertilizers, biological preparations and protection means against diseases and pests. The after-effect of the positive impact of the preparations was investigated in 2021 in a field experiment on studying the field germination of F1 seeds of the sunflower hybrid Fakel. It was found that during the formation of F1 seeds of the hybrid Fakel at the hybridization plot, the best results in terms of seed quality were obtained using a complex of fertilizers and chemical plant protection, where the highest values of the indicators of the yield structure were noted (diameter and formation of a head, seed amount per a head, 1000 seed weight, and volume weight). This made it possible in F1 to have lower losses of field germination for the formation of a scientifically based plant density. As a result of phytoexamination of grown seeds, it was revealed that the use of protective measures at the hybridization plot during the growing season of plants of the maternal form of the hybrid Fakel made it possible to increase the percentage of formed healthy seeds. The best data on the level of field germination of seeds were obtained when using biological plant protection and microbiological fertilizers at the hybridization plot. This ensured the smallest loss of germination at the scientifically grounded plant density of the hybrid Fakel in F1.

Authors:   All-Russian Institute of Plant Protection, Golubev A.S. , Borushko P.I. ,   All-Russian Institute of Plant Protection
Published: December 2021

Trials with a herbicide Acris, SE (280 g/l of dimethenamid-P + 250 g/l of terbuthylazine) were carried out in the Astrakhan, Krasnodar and Altai regions. The aim of this work is studying biological and economic efficiency of pre-emergence treatment with the combined herbicide Acris, SE on sunflower. The treatment with the herbicide Acris, SE (2.0–3.0 l/ha) made it possible to prevent many annual dicotyledonous weeds: Chenopodium album, Amaranthus retroflexus, Fagopyrum tataricum, Abutilon theophrastii and Solanum nigrum. Ambrosia artemisiifolia, found in the Krasnodar region, is less sensitive to this herbicide. The herbicide Acris, SE was highly effective in suppressing annual monocotyledonous weeds: Echinochloa crusgalli and Panicum miliaceum. Efficiency of the herbicide ACRIS was at the level of the standard Gardo Gold, and at the maximum application rate (3.0 l/ha) exceeded the standard one. Pre-emergence soil treatment with the herbicide Acris, SE did not have a negative effect on the germination of sunflower. Significant increase of sunflower yield was noted in all regions of trials. The most significant values were observed on varieties Flagman and R 453 in the Krasnodar region (8.7–9.2 and 7.0–7.5 quintal/ha, respectively). The lowest yields of sunflower in untreated control (10.2 and 11.0 quintal/ha) were observed in the Altai region, but the relative increase in yield in variants with the herbicide Acris, SE application was maximum (from 29.1 to 67.6% in relation to yields in untreated control). In the Astrakhan region, application rates of the herbicide Acris, SE of 2.5 and 3.0 l/ha were characterized by statistical significance (increases up to 2.5 and 3.2 quintal/ha, respectively).

Authors: Yadav Deepika , Singh Sanjay , Dhawan Benu , Sood Seema , Gupta Somesh
Published: November 2021

Background

Cervical discharge as part of cervicitis and pelvic inflammatory disease is a cause of significant morbidity in sexually active women worldwide. Non-gonococcal and non- chlamydial bacterial pathogens are becoming more prevalent.

Aims

This study aims to determine bacterial pathogens causing cervical discharge using culture and/or polymerase chain reaction and assess the clinical and laboratory response to the conventional syndromic kit regimen established by the World Health Organisation.

Methods

A retrospective review of records of women with cervical discharge over one year period. Culture and/or polymerase chain reaction results of endocervical swabs of various bacterial pathogens at baseline and after four weeks of treatment with syndromic kit regimen were recorded.

Results

A total of 70 case records were reviewed for clinical details, out of which results of bacterial culture and polymerase chain reaction were available for 67 cases. Infectious aetiology was found in 30 (44.7%) patients with Ureaplasma species being the most common organism isolated on culture (18, 26.8%) and polymerase chain reaction (25, 37.3%), respectively. Polymerase chain reaction for Chlamydia trachomatis and Mycoplasma hominis was positive in ten (14.9%) and four (6%) cases, respectively. None of the patients showed positive culture for Neisseria gonorrhoeae. Coinfection was seen in eight (11.9%) patients with the majority showing Chlamydia trachomatis and Ureaplasma spp. coinfection (five patients). Forty one cases (58.5%) received tab. cefixime 400 mg and tab. azithromycin one gram stat (kit 1), while 29 cases (43.3%) received tab. cefixime 400 mg stat, tab. metronidazole 400 mg and cap. doxycycline 100 mg, both twice daily for 14 days (kit 6). Minimal to no clinical improvement with treatment was seen in 14 out of 32 cases (44%) at the end of four weeks with the conventional kit regimen. Post-treatment culture and/or polymerase chain reaction were positive in nine out of 28 cases (32.1%) with Ureaplasma spp. being the most common.

Limitations

Retrospective study design, small sample size and fewer cases with follow-up data were the main limitations.

Conclusion

Ureaplasma spp. was the most common infectious cause of cervical discharge in our patients. Treatment given as part of syndromic management led to a clinical and microbiological response in around half and two-third cases, respectively.

Published: November 2021

Extra-nodal Natural killer/T cell lymphoma (ENKTL) is a well-defined and highly aggressive form of NonHodgkin’s lymphoma with a scarcity of cases reported in literature. The most common primary site of involvement is the nasal cavity followed by skin and the gastrointestinal tract (GIT). Cutaneous involvement is a rarity. More than 95% of cases are usually in association with Epstein Barr Virus (EBV) infection. EBV negative ENKTL can be similar in clinical, pathological, and prognostic characteristics with EBV positive ENKTL. This malignancy is usually characterized by its poor prognosis irrespective of clinical stage and therapy. We describe here, a 58-year-old man presenting with multiple nodular lesions over legs and trunk, had an ileal perforation later, and was diagnosed as ENKTL on the ileal biopsy specimen. This case is being reported in view of the fulminant clinical course of the disease, simultaneous involvement of the GIT and skin without nasal or midline involvement, the usefulness of immunohistochemistry in arriving at a diagnosis, and EBV negativity which is quite rare in the Asian population.
Innovative Activity: State Regulatory Legal Acts and Possibilities of Their Application in Library Practice
Authors: Guseva Evgenia N.
Published: December 2021

Innovative ways of the development of libraries is a topic that has a sufficient degree of elaboration. However, the documents that provide regulatory and strategic support for the creation and implementation of innovations, as well as the boundaries of their applicability in the library sphere, are not sufficiently examined. The article presents the regulatory legal acts and documents of the strategic planning system that influence the development of libraries and can be used to create and implement sectoral library development programs. Most of these documents have status of regulatory legal acts. They can be used as a conceptual and methodological basis for creating programs and strategies for the development of libraries, given that the availability of such documents has already become mandatory for many branches and organizations, not only in the industrial or commercial spheres of the economy.
Organisation and Maintenance of Library Authority Files in Russia and Abroad
Authors: Stukalova Anna A. , Balutkina Natalya A.
Published: December 2021

The article provides review of foreign and domestic publications on the problems of creation, development and use of authority files (AF) of names of persons, names of organizations, geographical names and other objects both at the international, national and regional levels. The paper presents analysis of the foreign experience of AF maintenance. The authors note that, due to the availability of universal collections and qualified specialists, AF formation abroad is usually carried out by national libraries. A substantive analysis of foreign publications has shown that national AFs (NAF) are characterized by data variability and diversity of approaches. The authors studied the experience of successful combination of NAF created according to different methods within the framework of the international corporate project — Virtual International Authority File (VIAF). The article notes that most of the Russian libraries do not use AF, since AF, created in republican and regional scientific libraries, as a rule, are not publicly available. At the same time, creation by a separate library of its own AF leads to high labour and material costs, and the formation of a large number of AF leads to the variability of the AFs created for the same objects. The authors conclude that for efficient use of AFs within the country, it is necessary to apply unified methods and rules for creation of authority records. Another way out is the application of the Semantic Web technology, which allows linking AFs created according to different methods. It is necessary to make maximum use of existing dictionaries or create dictionaries based on the World Wide Web Consortium (W3C), Resource Description Framework (RDF), RDF Schema (RDFS) and Web Ontology Language (OWL) standards.

Published: December 2021

The article discusses the issues of popularization of scientific knowledge on the basis of public libraries. The author substantiates the importance of library and information institutions in the process of spreading scientific knowledge among wider population. The article considers the problematic aspects and tasks of libraries in the direction of improving the scientific literacy of users.

The author characterizes the project “Information-Communication Platform for the popularization of Science”, developed by specialists of the Mikhail Lermontov Interdistrict Centralized Library System (St. Petersburg), which covers a wide range of scientific areas providing a general overview of topics and more specific information for those who wish to obtain in-depth sight into a particular subject area. Special attention is paid to the organizational issues of the implementation of platform: the purpose of creation, the target audience, the basic principles, the main objectives of the project. The article considers the forms of mutually beneficial cooperation in the popularization of scientific knowledge within the framework of the project with partner organizations. The author describes the requirements for the operation of interface. The platform contains three major types of information resources: documentary full-text data bases, bibliographic resources and media resources. The platform anticipates interactive communication of library users — students and representatives of pedagogical community — with well-known scientists for discussing technical developments and achievements of humankind with particular attention to subjects of current interest: pandemic, coronavirus, vaccination. The information-communication platform allows monitoring the interest of young people in various scientific areas. Participation in the project motivates young people to scientific activity, which is one of the basic factors of reproduction of scientific personnel potential.
Development of Digital Skills of Library Specialists in the Distant Format
Authors: Pilko Irina S.
Published: December 2021

Digitalization of the library sector requires library staff to develop digital competencies, information retrieval skills and new knowledge in the field of data processing. The purpose of the study was to identify the digital skills of specialists of public libraries and the opportunities for their development when mastering additional professional education programs with the use of distance learning technologies. Educational programs for advanced training of library specialists, implemented within the framework of the Federal project “Creative People” of the National project “Culture”, have become the basis for such work. The article analyses the experience of participation of the St. Petersburg State Institute of Culture in educational projects for professional development of practicing librarians using distance learning technologies, the topics of programs offered by the centres for continuing education and advanced training of creative and managerial personnel in the field of culture in 2019—2021. Programs of additional professional education give priority to the formation and development of digital skills in the following categories: information (information literacy), communication (communication and collaboration) and creative skills (creation of digital content). There is an obvious shortage of educational programs related to the formation of critical thinking of users of digital resources and information security. Communication skills of librarians participating in the Creative People project implemented in their willingness to undergo formal training remotely, in a positive attitude towards the distant forms of professional development, despite their labour intensiveness. It is established that in the structure of thematic preferences of library specialists for future training in the system of continuing professional education there prevail the topics related to the formation of information and communication competencies. The article notes that significant proportion of specialists who have mastered the advanced training program are not ready to clearly determine in what types of practical activities their knowledge and skills can be applied. The obtained results make it possible to correct the topics of educational programs of further professional education of library specialists, to clarify the list of priority didactic tasks and the tools of distance learning technologies used for their implementation.

Published: December 2021

The chemical and structural properties of atomically precise nanoclusters are of great interest in numerous applications, but the structures of the clusters can be computationally expensive to predict. In this work, we present the largest database of cluster structures and properties determined using ab-initio methods to date. We report the methodologies used to discover low-energy clusters as well as the energies, relaxed structures, and physical properties (such as relative stability, HOMO-LUMO gap among others) for over 50,000 clusters across 55 elements. We have identified 589 structures which have energies lower than any previously reported in the literature by at least 1 meV/atom, and we have identified 1340 new structures for clusters that were previously unexplored in the literature. Patterns in the data reveal insights into the chemical and structural relationships among the elements at the nanoscale. We describe how the database can be accessed for future studies and the development of nanocluster-based technologies.
Kinetic Probes of the Origin of Activity in MOF-Based C–H Oxidation Catalysts
Authors: Sur Aishanee , Jernigan Nicholas , Powers David
Published: December 2021

The development of homogeneous catalysis is enabled by the availability of a rich toolkit of kinetics experiments, such as the Hg-drop test, that differentiate catalytic activity at ligand-supported metal complexes from potential heterogeneous catalysts derived from decomposition of molecular species. Metal-organic frameworks (MOFs) have garnered significant attention as platforms for catalysis at site-isolated, interstitial catalyst sights. Unlike homogeneous catalysis, relatively few strategies have been advanced to evaluate the origin of catalytic activity in MOF-promoted reactions. Many of the MOFs that have been examined as potential catalysts are comprised of molecular constituents that represent viable catalysts in the absence of the extended MOF lattice, and thus interfacial sites and leached homogeneous species represent potential sources of catalyst activity. Here, we demonstrate that analysis of deuterium kinetic isotope effects (KIEs) and olefin epoxidation diastereoselectivity provides direct probes of the origin of catalytic activity in MOF-promoted oxidation reactions. These analyses support direct involvement of lattice-based Fe sites in the turnover-limiting step of C–H activation with Fe-MOF-74-based materials (i.e., the MOF functions as a bona fide catalyst) and evidence that Cu2-based MOF MIL-125-Cu2O2 functions as a solid-state initiator for solution-phase oxidation chemistry and is not involved in the turnover limiting step (i.e., the MOF does not function as a catalyst). We anticipate that the simple experiments described here will provide a valuable tool for clarifying the role of MOFs in C–H oxidation reactions.
ChemInformatics Model Explorer (CIME): Exploratory analysis of chemical model explanations

Published: December 2021

The introduction of machine learning to small molecule research – an inherently multidisciplinary field in which chemists and data scientists combine their expertise and collaborate – has been vital to making screening processes more efficient. In recent years, numerous models that predict pharmacokinetic properties or bioactivity have been published, and these are used on a daily basis by chemists to make decisions and prioritize ideas. The emerging field of explainable artificial intelligence is opening up new possibilities for understanding the reasoning that underlies a model. In small molecule research, this means relating contributions of substructures of compounds to their predicted properties, which in turn also allows the areas of the compounds that have the greatest influence on the outcome to be identified. However, there is no interactive visualization tool that facilitates such interdisciplinary collaborations towards interpretability of machine learning models for small molecules. To fill this gap, we present CIME (ChemInformatics Model Explorer), an interactive web-based system that allows users to inspect chemical data sets, visualize model explanations, compare interpretability techniques, and explore subgroups of compounds. The tool is model-agnostic and can be run on a server or a workstation.
Revisiting the chevrel phase: Impact of dispersion corrections on the properties of Mo6S8 for cathode applications
Authors: Helmbrecht Katharina , Euchner Holger , Gross Axel
Published: December 2021

While the Mo6S8 chevrel phase is frequently used as cathode material in Mg--ion batteries, theoretical studies on this material are comparatively scarce. The particular structure of the Mo6S8 phase, with rather loosely connected cluster entities, points to the important role of dispersion forces in this material. However, so far this aspect has been completely neglected in the discussion of Mo6S8 as cathode material for mono- and multivalent-ion batteries. In this work we therefore have studied the impact of dispersion forces on stability and kinetics of Mo6S8 intercalation compounds. For this purpose, a series of charge carriers (Li, Na, K, Mg, Ca, Zn, Al) has been investigated. Interestingly, dispersion forces are observed to only slightly affect the lattice spacing of the chevrel phase, nevertheless having a significant impact on insertion voltage and in particular on the charge carrier mobility in the material. Moreover, upon varying the charge carriers in the chevrel phase, their diffusion barriers are observed to scale linearly with the ion size, almost independent of the charge of the considered ions. This indicates a rather unique and geometry dominated diffusion mechanism in the chevrel phase. The consequences of these findings for the ion mobility in the chevrel phase will be carefully discussed.

Can Neutrophil to Lymphocyte Ratio and Monocyte to Lymphocyte Ratio Be Used in the Diagnosis of Childhood Tuberculosis?
Authors: ELMAS BOZDEMİR Şefika , ASLANER Humeyra
Published: November 2021

Objective: Neutrophil-lymphocyte ratio (NLR) and monocyte-lymphocyte ratio (MLR) are useful biomarkers of inflammation used to evaluate bacteremia, disease activity, recurrence rate, surveillance and prognosis in many diseases. In this study, we evaluated NLR and MLR of 92 children with tuberculosis versus 45 healthy children to show whether they can be used as inflammation markers. Aim of this study was to evaluate the diagnostic valure of NLR and MLR in childhood tuberculosis.Materials and Methods: In this retrospective study, hospital records of 92 children with tuberculosis were reviewed. The NLR and MLR values of the patients were compared with the control group of 45 healthy children.Results: A significant difference was found between NLO and MLO values between tuberculosis and control groups (p <0.001). A cut off value of NLR>1.41was optimal for discriminating patients with tuberculosis from controls (sensitivity 75%, specifity 82.2%, positive predictive value 89.6%, negative predictive value 61.7%). A cut off value of MLR>0.22 was optimal for discriminating patients with tuberculosis from controls (sensitivity 50%, specifity 91.1%, positive predictive value 93.3%, negative predictive value 53.2%).Conclusions: NLR and MLR can both be used as inflammation biomarkers in the diagnosis of childhood tuberculosis. Prospective and more comprehensive studies are needed to make a clearer decision.

Objective: The COVID-19 global event has affected human resources psychologically, behaviorally, and economically. In this study, the relationship between the effects of the COVID-19 event and perceived threat and social support was investigated based on the perceptions of dentists.Materials and Methods: The data were collected between December 1, 2020 and January 20, 2021 using an online questionnaire (n= 422). The dentists were queried about perceived threat and perceived social support in relation to COVID-19.Results: A significant relationship was found between the COVID-19 event and perceived threats such as the fear of infection, high-risk jobs, stigmatization, and distancing. A significant relationship was also found between the COVID-19 event and perceived social support.Conclusion: Ensuring their working conditions are more protective against COVID-19 can reduce dentists' fear of infection and perception of high job risk as well as perceptions of stigmatization and distancing. In addition, social support practices can be implemented during the pandemic to help dentists to be more motivated and provide better service.

The field of workplace communication has grown in the past 20 years to encompass the negotiation of identities and the role of power in collaboration. Nonetheless, identity struggles at work remain an underexplored phenomenon, particularly for emerging or marginalised professional groups such as tertiary language and learning advisors (TLAs) in higher education. In this article, we explore how challenges encountered in collaboration between TLAs and content specialist academics (CSs) in an Australian tertiary setting can impact the negotiation of professional identities as well as the success of the work. We draw on transcripts of meeting talk from two novice TLAs as they negotiate collaborative work with one CS in a postgraduate subject, and we use critical discourse analysis to demonstrate how power discursively manifests in the meetings. The study sheds new light on the complexities of collaborative work, manifested through interactions, in hierarchical professional environments.
O SABER COMO ENSINAR NAS LICENCIATURAS EM CIÊNCIAS DA NATUREZA DO INSTITUTO FEDERAL DE EDUCAÇÃO, CIÊNCIA E TECNOLOGIA DE RONDÔNIA (IFRO)

Este artigo objetivou compreender os processos do saber como ensinar nos cursos de licenciaturas em Ciências da Natureza do IFRO. Para tanto, analisou-se quatro Projetos Pedagógicos de Cursos, vigentes entre 2010/1 e 2015/2 e ficou evidenciado que o saber como ensinar precisa vincular as práticas pedagógicas desenvolvidas nos espaços escolares com as disciplinas curriculares dos cursos de formação inicial de professores. Tal vinculação possibilitará a interligação dos anseios sociais às necessidades oriundas do enredamento do ambiente educativo formal, que é a escola. A pesquisa também demonstrou que 72,7% dos Docentes Formadores (DFs) afirmaram que os cursos de licenciaturas em Ciências Biológicas, Física e Química garantiram o saber como ensinar. Ao justificar a afirmação, 39,4% dos DFs a fizeram apresentando clareza sobre a temática, 27,3% foram evasivos, 24,3% não responderam e 9% atribuíram a responsabilidade desse saber aos DFs licenciados em pedagogia.
TESTANDO A EFICIÊNCIA DAS AULAS PRÁTICAS NO APRENDIZADO DE BIOLOGIA, A PARTIR DE MATERIAIS DE BAIXO CUSTO

Um dos maiores desafios dos professores de Biologia ao lecionar no ensino médio, está na adequação de recursos didáticos alternativos no processo de ensino, de modo que facilite a mediação e a compreensão do conteúdo abordado. As aulas práticas como método de ensino é uma ferramenta importante e uma ponte de interação entre os conhecimentos científicos e empíricos. Pensando na escassez dos recursos didáticos enfrentada pelos professores, principalmente nas escolas publicas, o presente estudo teve como objetivo testar a eficiência de aulas práticas de biologia para o ensino médio, utilizando materiais de baixo custo. Foram selecionadas aulas práticas para os três anos do ensino médio. Para cada prática selecionada, os participantes tiveram uma aula teórica/expositiva prévia, com abordagem voltada ao assunto envolvendo a aula prática. Após a aula teórica, os participantes responderam um questionário de múltipla escolha referente o assunto abordado durante a aula teórica. Na sequencia foi realizada a aula prática correspondente à aula teórica ministrada. Após a aula prática, o mesmo questionário foi aplicado novamente. Análises com o uso de teste t-pareado e médias gerais de acerto foram realizadas para avaliar a eficácia da aula prática no processo de ensino-aprendizagem. Nossos resultados demonstram que, após as aulas práticas houve aumento significativo na aprendizagem dos discentes, evidenciando que a aplicação das mesmas, contribuiu de maneira eficiente, não só com o aprendizado do tema abordado na aula, mas também em outros temas relacionados.
MANGROVE ASSOCIATE BASED SHRIMP FEED: AN INNOVATION IN THE AQUACULTURE SECTOR
Authors: Sarker M. N.
Published: November 2021

The traditional method of shrimp culture is a common practice in Indian Sundarbans which is done without any sound scientific back-up, proper feed, and water quality management. The shrimp farmers use a traditional feed of animal origin that often results in deterioration of water quality and disease outbreaks in cultured species. The present paper highlights the effect of the total replacement of animal ingredients in shrimp feed with floral ingredients on water quality and shrimp health. Weight gain, condition index, feed conversion ratio (FCR), survival, body pigmentation (astaxanthin level) were analyzed in shrimps along with pond water quality. Higher condition index (C.I.) values, survival rate, and gain in shrimp weight were observed in the experimental pond (E) compared to the control pond (C). Low FCR values were observed in the experimental pond than in the control pond. Astaxanthin values in shrimps of the experimental pond were also higher than the control pond which points towards Suaeda maritima as the source of carotenoid in the shrimp tissue.
Programas de aprendizagem profissional: um estudo de permanência e êxito

Os programas de aprendizagem profissional (Programa Jovem Aprendiz), no âmbito da Rede Federal de Educação Profissional, Científica e Tecnológica, têm sido implementados com cada vez mais frequência. Segundo Villar e Mourão (2018), esses programas costumam aumentar a empregabilidade e a percepção de autoeficácia dos adolescentes e jovens participantes. Além disso, a possibilidade de formação omnilateral proporcionada pelos Institutos Federais, apontada por Mota et al (2018) e a dificuldade de inserção do jovem no mundo do trabalho estudada por Pfaffenseller (2014), tornam estas instituições estratégicas no fortalecimento da política pública. No âmbito do IFCE, o programa fora implantado a partir de 2017 nos campi de Pecém e Caucaia. Contudo, a literatura apresenta referenciais como os de Silva et al (2017) e Santos et al (2018), dentre outros, com considerações sobre a implantação deste programa em períodos anteriores. Como forma de contribuir na investigação do impacto da implantação programa, o presente trabalho apresenta um estudo de indicadores de permanência e êxito de estudantes do IFCE, com ênfase naqueles que participaram do programa Jovem Aprendiz. Os indicadores de permanência e êxito foram avaliados por meio de um formulário eletrônico aplicado a estudantes de dois cursos técnicos do campus. Os resultados demonstram que a implementação desse tipo de prospecto se apresenta como um instrumento relevante para a melhoria dos indicadores de permanência e êxito em cursos técnicos, especialmente, quando a própria instituição, posiciona-se como a entidade formadora do programa de aprendizagem.
