Published: July 2021

Background Academic stress is a mental distress originated from the anticipated frustration associated with academic failure. Whereas, emotional intelligence (EI) is a characteristic of an individual that determines the degree, and intensity with which they are able to understand and accept one’s own emotions as well as that of others. Aim and Objective The broad aim of the present study was to investigate an empirical-based examination of the relationship among academic stress and EI in high school students. The objectives of the study were to ascertain if there exist any gender, family structure and single child differences between academic stress and EI. Method This study is based on a quantitative analysis of the data. To collect validated data, purposive sampling was taken from varied streams and family structure of the age group 16 to 18-years; with no gender disparity. Student Academic Stress Scale (SASS) and emotional intelligence test (EIT) were used in this research. The data obtained was further validated through statistical techniques of correlation and analysis of variance (ANOVA) methods. Results The results showed an inverse correlation between EI and academic stress in high school students. The study also revealed single child and family structure factors are associated with the level of EI and showed an impact on academic stress of high school students.

Transients in electromechanical systems need to be modeled adequately if the existing electric drive control algorithms are to be improved, or new ones are to be developed. This fully applies to the electric drives of roll-ing mill stands. When studying such drives, one often needs to find a tradeoff between the complexity of Park-Gorev equation-based mathematical description of processes in variable frequency drives, and the capabilities of simpler models that adequately describe the processes relevant for each specific case. The latter include the known dual-mass model of the electromechanical system of a rolling mill stand featuring a flexible shaft and gaps in transmissions. Research presented herein covers the parameters of this model, which need to be ob-tained experimentally. The most accurate way to find the model parameters is to derive them from the oscillo-grams sampled on the object when running in typical transient. This particular paper addresses the electrome-chanical system of the horizontal stand in Plate Mill 5000 deployed at Magnitogorsk Iron and Steel Works (MMK PJSC). The paper substantiates the methodology behind parametrizing the system and shows how to cal-culate the moments of inertia of rotating masses from oscillograms of unloaded drive acceleration. To showcase the method, the paper presents finding the stiffness factor of an elastic coupling from the transients recorded when halting the electric drive. Focus is made on finding the time constants of the internal torque control cir-cuit as approximated by first-order or second-order filters. By comparing the simulation output against the os-cillograms sampled on the mill itself, the model was proven to adequately compute the parameters of the object. The paper concludes with recommendations on how the developed methods could be used to find the parame-ters of a dual-mass system when modeling the electric drives in rolling mills. The conclusions outline possible further research.

Authors:   T.F. Gorbachev Kuzbass State Technical University, Eshchin Evgeny
Published: July 2021

Variants of constructing control systems with a lagging argument for the positioning problem of an asyn-chronous electric motor (IM) and the problem of energy-saving AM control are considered. Variants of control of an asynchronous electric drive with IM on the basis of predicting its state are considered. The analytical de-sign of the predictor (ADP) is an asynchronous motor control algorithm based on the mathematical theory of optimal control (L.S. Pontryagin's maximum principle). The control algorithm (ADP) ensures the achievement of the minimum value of the target functional, which (functional), in contrast to the structure of the classical pre-dictive control system (Model Predictive Control - MPC), is clearly not part of the ADP. Calculations of the movements of an electric drive with an IM in the control modes of its state, taking into account delays along the channels for assessing its state and control, as well as using predictors, are given. The effectiveness of the in-troduction of predictors to improve the stability and quality of control of an electric drive with an IM has been established.

The article presents the results of the analysis of the main stages of the development of electric networks for housing and communal services (HCS) since the 50s of the last century and ending with the latest innovative developments, which are both at the stage of theoretical research and experimental tests in pilot projects implemented in existing networks. It is noted that the traditional 10(6)/0.4 kV structure with a dead-earth neutral on the low-voltage side, which is used both in industrial and utility networks, has disadvantages associated with increased power losses, as well as the need to use special technical means to ensure the required quality of electricity. It is shown that with the average value of the reverse sequence current coefficient equal to 0.3, the relative value of additional power losses in the low-voltage line from the presence of current in the neutral wire can reach 36% of the total amount of additional losses. The review and analysis of the four most promising areas of modern research, innovative developments and experiments on the structural optimization of utility networks is given: a network with an increased voltage of 6(10; 35) kV and a reduced voltage of 0.4 kV with an isolated neutral; a network with an increased voltage of 6 (10; 35) kV and a reduced voltage of 0.4 kV with an isolated neutral; 0,95/0,4 /0,23 A network with two levels of high voltage of 1.14 (0.66) kV and a reduced line voltage of 0.23 kV with a grounded neutral of transformers; Fundamentally new methods of transmitting electricity over a single wire at alternating and direct current of increased voltage are described. The necessity of choosing the most rational integrated circuit solution for the structure and schemes of utility networks, which will reduce the loss of electricity in the networks, improve the quality of electricity and electrical safety, is justified.

Published: July 2021

The thin layer drying characteristics of blanch-assisted water yam slices were investigated with respect to its un-blanched water yam slices in a convective hot air oven. The yam slices (diameter 4 cm; thickness 0.8 cm) were dried at temperatures 50, 60 and 70 °C, respectively with a constant air velocity of 0.13 m/s. The drying data obtained were fitted into six existing drying models: Page, Newton, Midilli, Henderson and Pabis, Logarithmic and Diffusion model. Non-linear regression analysis was used to determine the model parameters; the coefficient of determination (R2) and standard error of estimates (SEE) in order to determine the model best fit. The study showed that the drying process occurred in the falling rate drying period. The blanch-assisted slices had a faster drying rate than the un-blanched yam slices. Among the models, the diffusion model gave the overall best fit for the drying data obtained. The effective moisture diffusivity ranged from 3.18×10-8 to 4.47×10-8 m2/s for the blanch-assisted slices and from 4.73×10-8 to 7.33×10-8 m2/s for the un-blanched slices. The activation energies of the blanch-assisted and un-blanched yam slices were 15.5 kJ/mol and 20.1 kJ/mol, respectively. These processing conditions obtained for water yam flour would be suitable for its process design and control thereby enhancing its utilization and overall acceptability.

Growth and Development of the Introduced Picea L. (Karst.) Species in the Taiga Zone (Karelia)
Authors: Kishchenko Ivan T.
Published: July 2021

The study was conducted in the Botanical Garden of Petrozavodsk State University (South Karelia, the middle taiga subzone) from April to October during 1988–2016. The following representatives of the genus Picea were investigated: four introduced species (Picea glauca (Moench) Voss [syn. P. canadensis Britt.], P. pungens Engelm. f. viridis Regel., P. obovata Ledeb., and P. mariana Britt.) and one native species (P. abies (L.) Karst.). The growth of P. abies shoots starts 1–4 weeks earlier and ends 1–3 weeks later compared to the introduced species. The earliest culmination of shoot growth is observed in P. glauca and P. obovata and the latest in P. abies. The longest shoots are formed by P. abies. The growth dynamics of shoots differs considerably between the introduced species and the native species. The dates of the beginning and the culmination of the shoot growth in the studied species are to a certain extent affected by the temperature of the air. P. abies needles begin to grow 1–2 weeks earlier than the needles of the introduced species. The earliest culmination of needle growth is observed in P. obovata and P. glauca and the latest in P. pungens. P. abies and P. pungens show the largest needle length increment, while in the other species, it is 2–4 times smaller. The longest needles are formed in P. pungens and P. abies. There is a noticeable difference in needle growth dynamics between the introduced species and the native species. The dates on which needles begin to grow are largely determined by the temperature of the air. The temperature of the air and solar radiation produce a substantial effect on the time of occurrence of most phenophases in the studied Picea species. P. pungens and P. glauca were found to be the most promising spruce species for residential landscaping and creation of artificial plant communities in Karelia

Published: July 2021

Several types of transcendental systems of equations are considered: the simplest ones, special, and general. Since the number of roots of such systems, as a rule, is infinite, it is necessary to study power sums of the roots of negative degree. Formulas for finding residue integrals, their relation to power sums of a negative degree of roots and their relation to residue integrals (multidimensional analogs of Waring’s formulas) are obtained. Various examples of transcendental systems of equations and calculation of multidimensional numerical series are given

Influence of Chemically Modified Ultra-High Molecular Weight Polyethylene on the Properties of Butadiene Nitrile Rubber
Authors: Shadrinov Nikolay V. , Gogolev Vladimir D. , Isakova Tatyana A.
Published: July 2021

For the manufacture of frost-resistant oil and petrol-resistant rubber products, one of the most widely used rubbers is nitrile-butadiene rubber (NBR) with a low acrylonitrile content of 17–20 %. However, the technical properties of its vulcanizates do not always meet all high performance requirements. Therefore, the study of the possibility of improving the technical characteristics of vulcanizates based on frost-resistant NBR is an urgent task. This paper presents the results of studying nitrile-butadiene rubber BNKS‑18AMN filled with ultra-high molecular weight polyethylene (UHMWPE). A feature of this work is the study of the possibility of increasing the technical properties of the obtained elastomeric composites by increasing the interaction between chemically inert UHMWPE and BNKS‑18AMN using the chemical modification of UHMWPE. The modification of UHMWPE was carried out by chemical etching in a solution of chromic acid for 3 and 20 hours. A complex of laboratory studies of the obtained samples was carried out. The influence of the duration of chemical etching of UHMWPE on the rheological and vulcanization properties has been studied on the analyzer of the processing of rubber. It is shown that the filling of UHMWPE into BNKS‑18AMN, in general, leads to an increase in the viscosity of the rubber compound. Chemical etching of UHMWPE leads to a decrease in the rate of vulcanization and the density of the three-dimensional spatial structure of the vulcanizate. The study of the physical and mechanical properties in tension, wear resistance during abrasion and swelling in standard hydrocarbon liquid for testing rubbers SZR‑3 showed that chemical etching of UHMWPE leads to a decrease in strength characteristics, but at the same time leads to an increase in resistance to abrasion and has no significant effect on swelling. The study of changes in the properties of samples after heat exposure showed that chemical etching of UHMWPE significantly reduces the resistance to thermal oxidative destruction in the presence of atmospheric oxygen, but does not affect the resistance to thermal aging in the SZR‑3 hydrocarbon environment

Published: July 2021

Ülkemizde gelir dağılımı analizi için kullanılan en yaygın yaklaşımlar yüzde paylar ve Lorenz Eğrisi üzerinden hesaplanan Gini katsayısıdır. Parametrik olmayan bir yaklaşım olarak stokastik baskınlık, klasik yaklaşımlardan farklı bir yorumla gelir dağılımları arasında mikro düzeyde karşılaştırma sağlamaktadır. Lorenz eğrisinin hesaplama süreci stokastik baskınlık kriteri ile direkt ilişkilidir. İkinci Dereceden Stokastik Baskınlık (SSD) kriteri günümüzde daha çok finans alanında yapılan analizlerde kullanılırken Lorenz Eğrisi gelir dağılımı eşitsizliği üzerine yapılan analizlerde kullanılmaktadır. Bu çalışmada, Türkiye’de bölgeler arası gelir dağılımının keşfedilmesi amacıyla, TÜİK’in Gelir ve Yaşam Koşulları Araştırması 2007-2016 yılları arası anketleri İstatistiki Bölge Birimleri Sınıflamasına göre Düzey-1’e göre incelenmiştir. Bölgeler arası gelir dağılımı farklılıkları SSD kriteri ile karşılaştırılmakta ve bireysel gelirlerin birbirlerine baskınlığı incelenmektedir. Bireysel gelir dağılımlarının karşılaştırmalarından elde edilen sonuçlara göre; İstanbul ve Doğu Karadeniz diğer bölgelere en fazla sayıda baskınlık sağlayan bölgelerdir. Güney Doğu Anadolu bölgesinin hiçbir bölgeye karşı bireysel gelir dağılımları açısından baskın olmayan bir bölge olduğu söylenebilmektedir. Dolayısıyla SSD kriteri açısından değerlendirildiğinde gelir eşitsizliğinin, özellikle diğer bölgelere göre fazla sayıda baskınlık alabilen bölgeler ile baskınlık alamayan bölgeler arasında büyük boyutta olduğu söylenebilir. Çalışmada elde edilen bulguların bölgelere göre politika geliştirme sürecinde karar alıcılar açısından değerlendirilebilir nitelikte olduğu düşünülmektedir.
Gayri Resmi Değer Transfer Sistemlerinin Karapara Aklama ve Terörizmin Finansmanındaki Rolü: Hawala Sistemi

Published: July 2021

Gayri Resmi Değer Transfer Sistemleri (Informal Value Transfer Systems-IVTS), fonların veya değerlerin belirli bir coğrafi bölgeyle ilişkisi olan kişisel bir ağ yoluyla bir bölgeden diğerine taşınmasına ilişkin finansal hizmetlerdir. IVTS dünya çapında yaygın bir sitemdir ve çeşitli meşru ve gayri meşru amaçlar için kullanılmaktadır. IVTS’lerin en yaygın türlerinden biri, kara para aklama ve terörizmin finanse edilmesiyle ilişkilendirilen ve dünya çapında geçerli bir ödeme yöntemi olan Hawala sistemidir. Başlangıçta Hawala ağları Asya'da yüzyıllar önce İpek Yolu boyunca seyahat eden tüccarlar için güvenli para transferleri sağlamıştır. Fakat 11 Eylül 2001'de ABD Dünya Ticaret Merkezi’ne yapılan terörist saldırılardan sonra Hawala uluslararası basında “terörizm için kurulmuş bir bankacılık sistemi”, bir “uluslararası yeraltı bankacılık sistemi” olarak tanımlanmıştır. Bu çalışmada Hawala’nın ortaya çıkışı ve istikrarını sağlayan yönetişim mekanizmaları açıklanmaktadır. Çalışmada bu sistemlerin meşru yönleri korunurken, yasadışı kullanımını sınırlandırmak için etkili düzenleyici politikaların nasıl geliştirilebileceğine odaklanılmaktadır.
Kısmi Süreli İşlerin Kalitesi: Çoklu Doğrusal Regresyon Modeli ile OECD Ülkelerinden Bulgular
Authors: GÖRMÜŞ Ayhan
Published: July 2021

1970’den beri birçok gelişmiş ülkede giderek artış gösteren kısmi süreli istihdam, son zamanlarda düşük iş kalitesi ile gündeme gelmektedir. Çalışanların mutluluğuna katkıda bulunan ve doğası gereği çok boyutlu bir yapıyı temsil eden iş kalitesini ölçmek için farklı göstergeler kullanılmaktadır. Bu göstergeler arasında, örneğin OECD İş Kalitesi Çerçevesi kazanç kalitesi, işgücü piyasası güvencesi ve çalışma ortamının kalitesi olmak üzere üç temel boyutta yapılandırılmıştır. Bu açıdan, bu çalışma temel olarak, OECD ülkelerinin verilerini kullanarak, korelasyon ve çoklu doğrusal regresyon analizi yöntemleri ile kısmi süreli istihdam hacmi ile iş kalitesi göstergeleri arasındaki ilişkiyi incelemeyi amaçlamaktadır. Ampirik sonuçlar, daha yüksek kısmi süreli istihdam oranlarının, daha iyi iş kalitesiyle ilişkili olduğunu göstermektedir. Bu ilişki, kısmi süreli istihdam oranlarının gelişmiş OECD ülkelerinde daha yüksek, gelişmekte olan OECD ülkelerinde ise, daha düşük olmasının bir sonucudur. Ayrıca regresyon analizi; kazanç kalitesi, eğitim ve öğrenme ile kariyer ilerleme fırsatındaki artışın ve fiziksel sağlık risk faktörlerindeki azalmanın, kısmi süreli istihdam hacmini farklı derecelerde artırabileceğini ortaya koymaktadır.

Published: July 2021

The article is devoted to the review of conditional test generation, one of the most promising fields of natural language processing and artificial intelligence. Specifically, we explore monolingual local sequence transduction tasks: paraphrase generation, grammatical and spelling errors correction, text simplification. To give a better understanding of the considered tasks, we show examples of good rewrites. Then we take a deep look at such key aspects as publicly available datasets with the splits (training, validation, and testing), quality metrics for proper evaluation, and modern solutions based primarily on modern neural networks. For each task, we analyze its main characteristics and how they influence the state-of-the-art models. Eventually, we investigate the most significant shared features for the whole group of tasks in general and for approaches that provide solutions for them.
Real-Time Analysis and Processing of Cardiogram Signals
Authors: Yavorskyi A.
Published: July 2021

Analysis of Electrocardiogram (ECG) signals is an important task to save and enhance human life because a major cause of death is heart disease and the consequences. In many cases, early diagnostics of such problems can save and prolong life.

In this work, we develop and present an approach to the real-time detection of Atrial Fibrillation (AF) Arrhythmia, which is a common cardiac arrhythmia affecting a large number of people. Being undetected, it develops into chronic disability or even early mortality. At the same time, This disease is hard to diagnose, especially in its early stage. A real-time automatic and non-invasive effective detection is needed to help diagnose this kind of health problem early. In-time medical intervention can save human life. ECG as a record of the heart electrical activity is widely used for detecting different heart disabilities. At the same time, AF is hard to detect due to its non-regular nature, and also because the performance of detection models depends largely on the quality of data and careful feature engineering.

The research is based on the dataset from PhysioNet Computing in Cardiology Challenge 2017. It contains 8528 single-lead ECG recordings of short-term heart rhythms (9-61 sec.). Our method and the trained model reach the known state-of-the-art results in this field, but, at the same time, it is much less computationally intensive, and, thus, less power consumptive to be implemented in an embedded device.
Approximation of density of potentials for the flat viscoelastic bodies with inclusions, bounded by a piecewise smooth contours
Authors: Zatula N. I. , Zatula D. V.
Published: July 2021

An approach for approximating unknown densities of potentials in the study of the stressed state of a flat viscoelastic piecewise homogeneous body with inclusions, bounded by piecewise smooth contours, is proposed. The method is based on the construction of a system of boundary-time integral equations to determine the unknown densities of potentials along the contours of the inclusions. The approximation of the unknown densities of potentials was performed taking into account the singularity of the stressed state of a flat viscoelastic body near the angular point of the dividing line of the regions.
Cognitive impairments in schizophrenia in foreign studies: single function deficits or group of syndromes?
Authors: Karyakina M.V. , Rychkova O.V. , Shmukler A.B.
Published: July 2021

Cognitive deficit is the one of the key groups of symptoms in schizophrenia. These disorders reflect pathological processes in the central nervous system and are an important predictor of the social functioning recovery of patients. The question of the deficit structure remains open. In some cases, cognitive impairments are detected in early school age, in others, they appear only in adolescence. At the disease onset, there is a sharp deterioration in cognitive functioning. Further change is also heterogeneous: the same cognitive functions can either remain stable, or deteriorate or improve. To further study the cognitive deficit, it is necessary to distinguish more homogeneous groups based on both clinical parameters, and on the results of performing cognitive tests. It is important for the future of the concept of cognitive deficit to correlate it with the usual conceptualizations, including pathopsychological symptom groups.

Hallucinations and pseudo-hallucinations represent the most interesting disorders in the mentally ill; they are counted among the elementary deceptions of the senses. In my opinion, such a reckoning of them as deceptions of feelings is completely wrong, they must be attributed to deceptions of the mind, which I hope to prove further, pointing out that feelings are not deceived in them, and also that he is not at all elementary, but represent the result complex mental processes.

Annenkov, P.B. Romanova were used. In the field of justification of decisions on cargo terminals, determining the volume of tank farms with the possibility of their expansion O.B. Malikov, V.N. Sapronov. The application of multi-criteria rationalization by comparing the criteria under consideration is given in the work of A.T. Osminin, which developed a scientifically based method aimed at creating analytical and control systems. In the field of risk analysis and assessment of the work of A.G. Kotenko. The works of A.Y. Akhriev, A.B. Egorov, A.A. Kalushin, V.N. Mirushkin, E.V. Pasyunin, and A.V. Savelyev were studied in the field of improving the optimization of the oil transshipment complex, and the works of M.A. Nazarov and O.M. Sergeeva in the segment of logistics of river and sea oil transportation. Results: it consists in improving the quality of solutions to problems in the transportation of liquid fuel by means of transport in multimodal communication based on the use of the developed method. The set of criteria considered in the method allows you to set and solve transport problems with almost no restrictions on complexity, which in each case allows you to get better results. Conclusion: Using the method in practice allows not only to objectively find the best solution from the considered ones, but also to study hypothetical transportation schemes with the possible construction of new tracks and their elements, and compare existing and new schemes by a set of criteria, including construction costs and payback time of new tracks, and as a result find the best solution to the task.
Characterizing Fundamental Resonance Peaks on Flat-Lying Sediments Using Multiple Spectral Ratio Methods: An Example from the Atlantic Coastal Plain, Eastern United States
Authors: Schleicher Lisa S. , Pratt Thomas L.
Published: July 2021

Damaging ground motions from the 2011 Mw 5.8 Virginia earthquake were likely increased due to site amplification from the unconsolidated sediments of the Atlantic Coastal Plain (ACP), highlighting the need to understand site response on these widespread strata along the coastal regions of the eastern United States. The horizontal-to-vertical spectral ratio (HVSR) method, using either earthquake signals or ambient noise as input, offers an appealing method for measuring site response on laterally extensive sediments, because it requires a single seismometer rather than requiring a nearby bedrock site to compute a horizontal sediment-to-bedrock spectral ratio (SBSR). Although previous studies show mixed results when comparing the two methods, the majority of these studies investigated site responses in confined sedimentary basins that can generate substantial 3D effects or have relatively small reflection coefficients at their base. In contrast, the flat-lying ACP strata and the underlying bedrock reflector should cause 1D resonance effects to dominate site response, with amplification of the fundamental resonance peaks controlled by the strong impedance contrast between the base of the sediments and the underlying bedrock. We compare site-response estimates on the ACP strata derived using the HVSR and SBSR methods from teleseismic signals recorded by regional arrays and observe a close match in the frequencies of the fundamental resonance peak (f0) determined by both methods. We find that correcting the HVSR amplitude using source term information from a bedrock site and multiplying the peak by a factor of 1.2 results in amplitude peaks that, on average, match SBSR results within a factor of 2. We therefore conclude that the HVSR method may successfully estimate regional linear weak-motion site-response amplifications from the ACP, or similar geologic environments, when appropriate region-specific corrections to the amplitude ratios are used.
Targeting the Neuropeptide Y System in the Locus Coeruleus
Authors:   , Theisen Catherine Corrine , Van Bockstaele Elisabeth J.
Published: July 2021

Neuropeptide Y (NPY), a neurochemical mediator of stress resilience, may possess therapeutic efficacy in stress-induced opioid abuse and relapse. The locus coeruleus (LC)-noradrenergic system is an important target for therapeutic development for opioid abuse, as it modulates arousal and stress and is significantly regulated by opioids. Hyperactivity of the LC-norepinephrine (NE) system during opioid withdrawal contributes to many of the somatic and affective symptoms of opioid withdrawal. Alpha2-adrenergic receptor (AR) agonists, because of their auto-inhibitory function, restrain LC-NE hyperactivity and are FDA-approved to mitigate opioid withdrawal symptoms; however, they carry significant negative side-effects, including hypotension. We investigated adaptations in the anti-stress NPY system in the LC, following chronic morphine exposure and naltrexone-induced withdrawal in male and female rats. NPY exerts an inhibitory influence on the LC-NE system and its dysregulation would contribute to enhanced LC-NE activity. Results showed that there were no baseline differences in NPY levels in the LC across sexes. Chronic morphine significantly decreased NPY levels in both sexes. Naltrexone-induced withdrawal also decreased NPY from baseline in both sexes; however, NPY levels in males were further decreased when compared to morphine-only male counterparts. NPY in naltrexone-only groups was unchanged compared to controls, irrespective of sex. Relative RNA expression analysis in the LC showed that naltrexone-precipitated withdrawal decreased NPY compared to baseline and chronic morphine levels in both sexes. To determine the anatomical basis for functional interactions between NPY and LC neurons, we defined the synaptic relationship between the anti-stress NPY system and the pro-stress corticotropin-releasing factor (CRF) system in the LC that provides an excitatory influence on noradrenergic neurons. Results showed that NPY and CRF were co-localized in the same LC axon terminals, and revealed a complex organization with NPY receptors. Taken together, the results demonstrate that opioid-induced decreases in NPY transmission contribute to dysregulation of LC activity by promoting enhanced neuronal excitation via removal of an endogenous inhibitory drive impacting noradrenergic neurons. Decreasing the NPY inhibitory influence in axon terminals that co-localize excitatory neuromodulators, such as CRF, creates an imbalance in homeostatic regulation of LC neurons, leading to hyper-arousal and increased anxiety. Targeting the NPY system may, therefore, be a novel therapeutic target for stress-induced opioid abuse by restoring homeostasis to a dysregulated noradrenergic system.
To Teach or Not to Teach in Title 1 Schools : An Explorative Study on Preservice Teachers Motivation
Authors:   University of Oklahoma, Wang Qian , Lewis Laura ,   University of Oklahoma
Published: July 2021

This study aims to explore preservice teachers' motivations to teach at Title I schools as well as whether their motivations differ based on how far they are in their teacher education program. A total of 128 preservice teachers from two groups with different numbers of field experiences were surveyed. Preservice teachers cited extrinsic, altruistic, intrinsic, and past learning experiences as main reasons motivated them wanting to teach at Title I schools upon graduation. Their motivations might change due to the influences from professional training and social experiences. It was also found that in both groups there were many preservice teachers undecided whether they wanted to teach at Title I schools or not. Implications for research and practice are discussed.
Does Collaboration in Teaching Situations Help in Enhancing Teacher's Job Satisfaction?
Authors:   Indiana University, Bharaj Pavneet
Published: July 2021

Collaboration dismantles the compartmentalized structure of educational organizations and creates a safe and supportive environment for its teachers. This helps them to share valuable knowledge related to content or pedagogy, with the common interest of creating a better learning environment for the students. Collaboration supports teachers in instructional practices as well as contributes to their job satisfaction. The structure of this paper is guided by theoretical frameworks by DuFour, Eaker, and DuFour's (2005) on collaboration, Bandura's (1977, 1982) social cognitive theory, and Herzberg's (1987) theory of motivation and hygiene. The data from United States teachers' from The Teaching and Learning International Survey (2013) was used to explore the relationship between collaboration, instructional practices, and job satisfaction using structural equation modeling. The results showed that collaboration among teachers cannot directly predict the level of job satisfaction, but significantly predicts job satisfaction when mediated through the use of instructional practices.

The Role of Prior Experiences in Black Science Pre-Service Teacher Career Decisions
Authors:   Morgan State University, Smith-Mutegi Demetrice
Published: July 2021

In this study, framed in Expectancy Value Theory (EVT) and Factors Influencing Teaching (FIT) Choice model, I employed an explanatory sequential mixed methods research design to explain which factors influence Black novice and pre-service teachers (NPSTs) to pursue a career in science education. Drawing from EVT, FIT Choice® theory provided a theoretical framework explicitly focused on the antecedent experiences, values, and expectancies of success influencing teaching career choice. Based on this study’s results, Black NPSTs are motivated by many factors, including factors of social utility, ability, and career, and subject area interest. These factors are primarily influenced through prior teaching and learning experiences, such as informal summer camp experiences and tutoring. Understanding the factors that influence Black novice and pre-service teachers to pursue science teaching can help address future recruiting and retention efforts in primary and secondary schools.
Disrupting Intergenerational Poverty Through a Place-Based Education Initiative : A Review of Promise Neighborhoods in their First Decade
Authors:   Drexel University, Sterin Kim
Published: July 2021

This study explains the complexities of attainment, implementation, and evaluation of the U.S. Department of Education's Promise Neighborhood (PN) initiative. PNs seek to disrupt intergenerational poverty through a place-based education initiative that creates a pipeline of health, social, and education resources within an economically distressed neighborhood in an urban, rural, or tribal setting. The PN implementation grantees manage a network of school-community partnerships aiming to support students from cradle to career. This study includes an analysis of the complexities of PN attainment with a focus on the PN grant awardees; the complexities of PN implementation with a focus on PN management and services; and lastly, the complexities of evaluation with a focus on the PN evaluation factors. Recommendations for the future of the PN initiative are discussed.

Authors: Clark Wayne , Lavoie Josée Gabrielle , Nickel Nathan , Dutton Rachel
Published: July 2021

To monitor the progress of the COVID-19 outbreak, ensure equitable access to testing and treatment, and provide up-to-date information to Indigenous decision-makers engaged in setting up measures to protect their communities, the Manitoba Inuit Association (MIA) mobilized to work with the First Nation Heath and Social Secretariat of Manitoba, Ongomiizwin Research, and the Manitoba Government to identify Inuit in COVID-19 diagnostic tests, including Inuit who reside in Manitoba or those who come from Nunavut to the province to access health services. Provincial work was already underway to add Indigenous identifiers into provincial clinical health information systems; however, it was apparent early in April 2020 that reporting to Indigenous organizations on identified COVID-19 cases for First Nation, Metis, and Inuit People would be also be required in order for remedial measures to occur. This article describes the governance considerations needed to establish an information-sharing agreement with the Government of Manitoba and the role of the MIA in overseeing this process. Further background information is provided in addition to an extended discussion around the context in which Inuit are identified and receive healthcare services in Manitoba.
