Deuteron-proton isotope correlation spectroscopy of molecular solids
Authors: Welton Claire , Trébosc Julien , Jain Sheetal , G N Manjunatha Reddy
Published: November 2022

A dissolution followed by recrystallization from a deuterated solvent allows the site-selective deuteration of labile protons in molecular solids. High yields of deuteration obtained by this approach facilitates the structure elucidation of powdered solids by solid-state NMR spectroscopy, for example, by acquiring 1D 2H and 2D 2H-1H correlation NMR spectra with short experimental times. Along these lines, we present a cross-polarization 2H-1H isotope correlation spectroscopy (CP-iCOSY) approach for the characterization of deuterated amino acids and pharmaceutical compounds. We show that the high field NMR (28.2 T) coupled with fast magic-angle spinning (MAS) overcomes the sensitivity and resolution barrier for acquiring 2H MAS spectra, enabling the rapid detection of 2H peaks in a few seconds to minutes. Specifically, two-dimensional 2H-1H CP-iCOSY experiment allows the local structures and through-space interactions in a partially deuterated compounds to be elucidated. Analysis of partially deuterated L-histidine·HCl·H2O and dopamine.HCl is presented, whereby the detection of 2D peaks corresponding to 2H-1H pairs separated by >4 Å demonstrates the sensitivity and resolution power of the presented approach for the characterization of solid-state packing interactions. 2D ssNMR results are corroborate by NMR crystallography analysis using Gauge Including Projector Augmented Wave (GIPAW) approach. Molecular-level analysis enabled by this study is of considerable interest for further investigation of labile sites in a variety of molecular solids, reactive surfaces and interfaces, and supramolecular assemblies.
Lines in the Sand(bar): Collective Perspectives and Shifting Temporalities in Char... The No Man's Island
Authors: Chakraborty Amrita
Published: November 2022

The tasks of documenting and narrating stories of climate change and border environments have become increasingly urgent in recent years, and discussions around effective approaches to environmental storytelling have intensified accordingly. The film Char… The No Man’s Island (2012), directed by Sourav Sarangi, is a noteworthy example of a work that seeks to represent one such unstable environment that exists on the border between India and Bangladesh and to explore the daily lives of the beings who inhabit it. Although the documentary has a specific regional focus, its scope is far from limited, as the film examines various dimensions of life in this border environment as well as the historical and political factors that have led to the current realities of the space and the communities established there. In this paper, I examine how Sarangi’s inclusion of a multitude of distinct human and non-human perspectives throughout the film signals a move towards a form of environmental storytelling grounded in the notion of a collective, wherein narrative agency is distributed amongst multiple entities rather than invested in a single individual. Moreover, the paper argues that the usage of these various perspectives also enables Char to depict alternate temporalities and experiences of time which contrast heavily with ideas of linear time and progress and invites audiences to consider the multifaceted temporal and spatial realities of life in a precarious border environment.
Geological Afterlives of Sand in the Taiwan Strait
Authors: Zhu Chencong
Published: November 2022

This essay foregrounds the processes and ramifications of sand’s extraction, displacement, and reassembly as critical material and political junctures to unfold the cross-strait geo-political impasse between the “two Chinas.” These processes, termed “geological afterlives of sand,” brought the gulf of waters between Xiamen and Kinmen to the fore. In this fluid space where border is ideologically fraught, sand has become a critical bordering entity that enables the encounter between geology and cross-strait politics. By focusing on sand’s mobile and malleable agency in rearranging geo-political order in this region, this essay draws on cartographic technology and documentary depiction of sand’s multifaceted metamorphoses to present and negotiate what it means for human and nonhuman actors to live through sand's afterlives of displacement.

The aim of this study is the determination of optimum process parameters which will provide the finest and the most uniform electrospun Polyvinylpyrrolidone (PVP) based nanofibers with Taguchi experimental design. For the designed experimental setup, parameters (solvent type, polymer concentration, voltage, distance between the electrodes, solution feed rate and humidity) were used which effect the electospinning process significantly. For this purpose, the appropriate orthogonal array was selected to determine the factors and levels at Taguchi experimental design application. The experimental design aimed which provides to be reduced the number of experiments and minimised the effect of uncontrollable factors with less experiments to obtain target value by using Taguchi orthogonal arrays. In the experimental studies of paper, firstly PVP polymer solutions such as conductivity, surface tension and viscosity were determined with various PVP concentrations (10, 12, 14 wt %) and solvents (ethanol, dimethylformamide, dimethylacetamide, chloroform, acetic acid and distilled water). Scanning Electron Microscope (SEM) images of electrospun PVP based nanofibrous surfaces were obtained, average fiber diameter and fiber diameter coefficient values were calculated by ImageJ image analyses software and fiber diameter distribution histogram curves were obtained by SPSS program. Experimental results were analyzed and commented by Taguchi method in MINITAB program with variance analysis. According to the results; solvent type has the highest effect on the electrospinning of PVP nanofibers. In this study, it is predicted to save in terms of time and cost with decreasing the number of experiments by Taguchi experiment design.

Authors: YÜKÇÜ Sılay Aytaç
Published: November 2022

In this study, the beta function that is encountered in computational mathematics and physics is analyzed. The correct evaluation of this function also affects the accuracy of other mathematical functions in quantum mechanical calculations. Especially in recent years, there is an interest in studies related to the beta function for zero and negative p and q integers. This study, considering the neutrix limits of the beta function, presents new relations for the numerical computation of the beta function, especially for negative integers p and q. In addition, taking into account the definition of the beta function for positive p and q integer values, an algorithm is created to calculate the function for all integer values. Finally, numerical results obtained with the help of our new recurrence relations and algorithm are presented.
Investigation of Radiation Properties of CO2 Reacted Portland
Authors: AKSAKAL Hüsnü , ÇİNĞİLİ Vildan
Published: November 2022

In this study we explored the radiation properties of CO2-reacted Portland which take place in kiln process of cement production. The use of CO2 can change Portland density via chemical process to obtain CaCO3. When the CO2 capture rate of Portland cement is zero, the density is 2.3 g/cm3, while the CO2 capture rate is 100%, the density is reached to 2.705 g/cm3. The radiation shielding properties were explored using FLUKA code. To define the radiation shielding properties of the CO2-reacted Portland, four types of beams (photons, electrons, protons and neutrons) were used. These beams have been used to explain the leptonic and hadronic interactions. The CO2-reacted Portland radiation length and density have been calculated and presented. The energy depositions of four beams with various beam energies were examined by considering density variation of the cement. It has been found that CO2-reacted Portland has more efficient radiation shielding than traditional Portland materials. The carbonization of Portland will be carried out during the kiln process, not by the CO2 diffusion process, which is a very slow process, but by the faster and more convenient spray method.

Authors: AKDEMİR Selda
Published: November 2022

In this study, two-electron one- and two-center Coulomb integrals with the same and different screening parameters are investigated numerically in the real Slater type orbital (STO) basis using Fourier transform method. In momentum space firstly, for atomic, i.e. one-center, Coulomb integrals are calculated, and analytical expressions are obtained in terms of binomial coefficients. Then, the solutions of the two-center Coulomb integrals are made with the modified Bessel function of second kind and the results are expressed in terms of binomial and Gaunt coefficients, irregular solid harmonics, and finite sum of STOs. A computer program is written in the MATHEMATICA language to determine the accuracy of the analytical expressions that are highly suitable for programming. The numerical results obtained from the program are given in the tables, and it is shown that the results agree with the literature.

Published: November 2022

Indonesia is one of the countries that is often a transit point for immigrants who want to seek asylum in other countries. This illegal arrival is certainly very detrimental to Indonesia. This is because the arrival of these refugees is considered a threat to national security and resilience. The trend of the number of refugees that continues to increase every year has caused various problems in handling foreign refugees in Indonesia. Indonesia did not ratify the 1951 Refugee Convention and the 1967 Protocol, but on the basis of human rights. As a transit country, Indonesia is experiencing a build-up of refugee flows due to the uncertain timing of the status granting process from UNHCR and moreover third countries limit the acceptance of refugees. However, Indonesia continues to provide various forms of assistance in dealing with the problems faced by refugees. The government has also issued several regulations including Presidential Decree Number 125 of 2016 and other technical regulations. Indonesia also collaborates with non-governmental institutions, such as academics, humanitarian activists, and faith and charity-based organizations. This collaboration has implications for the existence of asylum seekers and refugees in Indonesia. It is hoped that with this regulation and cooperation, it can provide legal certainty regarding solutions to refugee problems in Indonesia.

Published: November 2022

Pangasius hypophthalmus (panga fish) is farmed in the Mekong River (Vietnam), which is known as a polluted river, and exported to many countries. The present study aimed to determine heavy metal levels in frozen panga fillets imported from Vietnam as well as the risks of heavy metals to human health. Panga fillets belonging to four brands were bought from three supermarkets in Adana city, Turkey, and heavy metals (As, Cd, Hg, Pb, Ni, Cu, Mn and Co) were analyzed. To analyze the potential risks to human health, EWI (estimated weekly intake), THQ (target hazard quotient), and CR (lifetime cancer risk) values were calculated to assess the potential risks to consumer health of the metal content in panga fillets. The health risk assessment values were calculated for children and adults according to the frequency of consumption once, three and seven times a week. The results revealed that the presence of heavy metals in the studied panga fillets was below permissible limits indicated by WHO (World Health Organization), EPA (United States Environmental Protection Agency) and TKB (Turkish Fisheries Laws and Regulations). The EWI, THQ or ∑ THQ and CR values were below PTWI (provisional tolerable weekly intake), 1 and 10-5, respectively. Remarkably, the highest values of the EWI/PTWI ratio and THQs were found for children.
Mapping the Contributions of the Review of Educational Research to Education, 1931–2020
Authors: Hallinger Philip
Published: November 2022

The goals of this bibliometric review of the Review of Educational Research were to gain insights into the evolution of the journal and identify its key contributions to the education literature. Bibliographic data associated with the full set of 3,022 review articles published in RER from 1931 through 2021 were exported from Scopus for bibliometric analysis using VOSviewer software. The review confirmed that RER remains rooted in the American education context, with scholars located outside the United States accounting for only 6% of the RER corpus. The review identified authors and documents published in RER that have had the greatest impact on the broader education literature. Author co-citation analysis visualized the “intellectual structure” of the RER corpus, which is anchored by a “school of thought” associated with Teaching and Learning Strategies and Effects. This research stream has been informed by complementary schools of researchers who have generated theory and research on cognition, teaching, and learning as well as motivation and learning. Although conceptual reviews of research are more prominent, meta-analytic reviews have also come to represent a key pillar in the intellectual structure of RER. Journal co-citation analysis validated the centrality of RER’s place within a community of highly ranked education and psychology journals. The findings confirm the strong disciplinary influence of psychology in shaping the journal’s direction and content. Adapting to a changing global research landscape in education was identified as a key challenge facing RER in the next decade.

In the present era of climate change and global warming, high temperatures have increased considerably, posing a threat to plant life. Heat stress affects the biochemistry, physiology and molecular makeup of the plant by altering the key processes, i.e., photosynthesis, respiration and reproduction which reduces its growth and development. There is a dire need to manage this problem sustainably for plant conservation as well as the food security of the human population. Use of phytohormones to induce thermotolerance in plants can be a sustainable way to fight the adversities of heat stress. Phytohormone-induced thermotolerance proves to be a compelling approach to sustainably relieve the damaging effects of heat stress on plants. Salicylic acid (SA) is an essential molecule in biotic and abiotic defense response signal transduction pathways. When supplied externally, it imparts heat stress tolerance to the plants by different means, viz., increased Heat Shock Proteins (HSP) production, Reactive oxygen species (ROS) scavenging, protection of the reproductive system and enhancing photosynthetic efficiency. The effect of SA on plants is highly dependent on the concentration applied, plant species, plant age, type of tissues treated, and duration of the treatment. The present review paper summarizes the mechanism of thermotolerance induced by salicylic acid in plants under heat stress conditions. It includes the regulatory effects of SA on heat shock proteins, antioxidant metabolism, and maintenance of Ca2+ homeostasis under heat stress. This review combines the studies conducted to elucidate the role of SA in the modulation of different mechanisms which lead to heat stress tolerance in plants. It discusses the mechanism of SA in protecting the photosynthetic machinery and reproductive system during high-temperature stress.
Effectiveness of dynamic neuromuscular stabilisation for improving trunk control in hemiplegic stroke: A scoping mini review
Authors: Raghumahanti Raghuveer , Chitkara Ekta , Agarwal Parul Raj
Published: November 2022

Stroke is one of the leading causes of mortality and morbidity in the adult population, resulting in significant cognitive and sensorimotor impairments affecting one-half of the body in most patients. The limitations that are attributed to trunk impairment affect the postural and respiratory functions due to either spasticity or weakness of trunk muscles, including the diaphragm. Physiotherapy is effective in interdisciplinary stroke management, with approaches utilising the principles of plasticity. This review focused on briefing the pathomechanical aspects of trunk impairment in hemiplegic stroke. The proposed mechanisms of Dynamic Neuromuscular Stabilization (DNS) as a treatment for hemiplegic stroke were analysed, and the existing research evidence for the efficacy of DNS in improving trunk control among stroke participants was critically reviewed. The findings substantiate the need for high-quality trials, emphasising study design, subset size, reflective outcomes, and regulated follow-ups.
The Many Faces of Monetisation: Understanding the diversity and extremity of spending in mobile games via massive-scale transactional analysis
Authors: Zendle David , Flick Catherine , Cutting Joe , Deterding Sebastian , Petrovskaya Elena , Drachen Anders
Published: November 2022

With the rise of microtransactions, particularly in the mobile games industry, there has been ongoing concern that games reliant on these obtain substantial revenue from a small proportion of heavily involved individuals, to an extent that may be financially burdensome to these individuals. Yet despite substantive grey literature and speculation on this topic, there is little robust data available. We explore the revenue distribution in microtransaction-based mobile games using a transactional dataset of USD 4.7bn in in-game spending drawn from 69,144,363 players of 2,873 mobile games over the course of 624 days. We find diverse revenue distribution in mobile games, ranging from a ‘uniform’ cluster, in which all spenders invest approximately similar amounts, to ‘hyper-pareto’ games, in which a large proportion of revenue (~38%) stems from 1% of spenders alone. Specific kinds of games are typified by higher spending: the more a game relies on its top 1% for revenue generation, the more these individuals tend to spend, with simulated gambling products (‘social casinos’) at the top. We find a small subset of games across all genres, clusters, and age ratings in which the top 1% of gamers are highly financially involved– spending an average of USD 66,285 each in the 624 days under evaluation in the most extreme case. We discuss implications for future studies on links between gaming and wellbeing.
The Implication of Solar Chimney for Enhanced Stack Ventilation
Authors: Shrestha Manzil , Uprety Sanjaya
Published: November 2022

In this study the effect of a solar chimney in enhancing the stack ventilation in an e-Bike Prototype Assembly building is analyzed. The Study area is Birgunj, Nepal. Natural ventilation in the existing plans is studied and compared with an alternate scenario of incorporating a solar chimney. Various parameters like temperature (Air, operative and radiant), pressure and velocity distribution, and comfort parameters (PPM and PPD) are compared. The DesignBuilder software is used to analyze natural ventilation. DesignBuilder internal CFD analysis is used to study the effect of solar chimney as a part of the building on the natural ventilation. Results show that there is significant improvement in ACH and air movement inside the building with incorporation of Solar Chimney. The PPD analysis results show that the comfort aspect is not only related to a single parameter like the air flow, temperature and pressure differential but a combination of these. The design of solar chimney should not only focus to improve a single aspect but a combination of the entire parameters for overall comfort. The study also shows that internal CFD analysis can be effectively used to predict internal condition of a building. The performance of Solar Chimney can be measured either or wholly in terms of air movement/air flow, temperature and velocity distribution and also thermal comfort parameters like PPD and PMV.
Deciphering the geochemistry of two key Paleoproterozoic siliciclastic sequences of the Piedra Alta Terrane (Río de la Plata Craton, Uruguay)

Published: November 2022

The geochemistry of two metavolcano-sedimentary sequences deposited in the Piedra Alta Terrane is compared, and their geotectonic evolution is discussed. The Ojosmín Unit (OU) comprises MORB-like basic rocks at the base and a fine-grained siliciclastic sequence interpreted as marine turbidites towards the top. The succession was later obducted during the Orosirian. Whole-rock geochemistry of the metasedimentary rocks of the OU indicates the lack of source rock alteration during deposition (Chemical Index of Alteration, CIA ca. 40-53), implying ice-house climatic conditions in correlation with the worldwide Rhyacian glaciations. Recycling of zircon fractionates the Rare Earth Elements (REE) increasing the amount of HREE, Y, and Hf. Variation ranges of Th/Sc (0.4-4.9), Zr/Sc (30-410), Th/U (2.5-4.3), and of the Eu/Eu * negative anomaly (0.4-0.7) approximate Upper Continental Crust (UCC) values. A new clastic metasedimentary, gently folded unit, the Cerro de la Figurita Formation (CFFm), is erected. The CFFm clastic sedimentation (3,000 m in thickness) represents a deepening upward sequence, starting with polymictic conglomerates deposited in an alluvial fan-dominated environment that evolves to marine turbidites. The CFFm is probably related to a foreland geotectonic setting developed during the Orosirian. The geochemistry of the CFFm reveals similarities to unrecycled UCC, and weathering of the source rocks increases up section (CIA 45-92). Low ratios of Th/Sc (0.3-1.5), Zr/Sc (6-20), Th/U (3-6), high Cr/V (1.1-12.2), and a less pronounced Eu/Eu* negative anomaly of certain samples (0.5-0.9) suggest a contribution from mafic source rocks (probably ophiolitic).

Authors: Silva Rodrigo Ozelame da , Perez-Cassarino Julian , Steenbock Walter
Published: November 2022

This research aims to identify the main multiplication strategies of native tree species in the Atlantic Forest biome, or simply native fruits, and to propose a way to stimulate their promotion. The audience was made up of six groups of farmers from the Núcleo Luta Camponesa of the Ecovida Agroecology Network, located in the south-central region of the State of Paraná-BR. The methodological procedures used the principles of action research and consisted of four complementary phases. The first sought to problematize the importance of native fruits and choose priority species, while the second focused, in a participatory manner, on characterizing the socio-environmental aspects of priority native fruits. Outstanding results are the identification of agroforestry systems as the best strategy for multiplication in the researched context, as well as the elaboration of a guide that can support the rescue and multiplication of such species in other territories. This guide is based on the following sequence: i) rescue looks for native fruits; ii) from what exists in agroecosystems; iii) exchange seeds and seedlings with farmers from other contexts; iv) plant in landscapes that farmers manage.
Biological Control
Authors: Rodríguez Alda , Chia Eduardo , Rossi Virginia
Published: November 2022

Agroecology proposes to mobilize the scientific and practical, traditional and local knowledge of producers to develop jointly new production systems. This article presents the results of research on biological control carried out since 2003 in the north of Uruguay. Experiences were conducted by different organizations of family farmers and by BIO-Uruguay (Batoví Instituto Orgánico), a social organization founded by family farmers and rural inhabitants. The results of the analyzed experiences are technical, methodological and social, focusing mainly on the biological fight against pests and diseases of agricultural and livestock production. The different stages of the co-innovation process are presented to obtain biological solutions from the recognition and use of native pathogenic fungi to control pests of economic importance. The objectives of this study were to restore biological balances, to contribute to the agroecological transitions of the productive systems, and to enforce the collective learning, necessary among the actors, for co-innovation. These learnings contribute to the development of the individual and institutional capacities needed to "build agroecology" in Uruguay.
One Archaeology of Knowledge Constructs
Authors: Menezes Costa Diogo
Published: November 2022

Not far from a critique, this paper also intends to be a thought about the symbolic and ideological inequalities – conscious or unconscious – inequalities from the archaeologist’s agency, in the internal and mental process of the archaeological construction of knowledge. Here, my understanding is a little more epistemological than practical, as a branch of philosophy that deals with the character of knowledge, and how we know what we know. In this essay, I ask what constitutes archaeological knowledge, its construction, its limits, its veracity, and its validation. Because an epistemology of archaeology is also a theory of knowledge (and there are many of them in archaeology today), and for some decades it has also been a central theme of philosophy of archaeology.
Adolescents’ interpersonal cognition and self-appraisal of their own anxiety in an imagined anxiety-provoking classroom presentation scenario: Gender differences
Authors: Ranta Klaus , Inkinen Mauri , Laakkonen Eero , Ståhl Hanna-Riitta , Junttila Niina , Niemi Päivi M.
Published: November 2022

Oral class presentations are regularly assigned to adolescents, but often provoke social anxiety, due to the importance of peer approval and need to appraise oneself as normal. Also, little is known about gender differences in girls’ and boys’ interpersonal cognition and appraisals of anxiety and self in anxiety-provoking speech situations. We examined gender differences in interpersonal cognition and appraisals of anxiety in an imagined class presentation scenario in a normative sample of 687 adolescents, 14-16-years-old, from Southwest Finland. Measures included the Classroom Questionnaire of Social Anxiety and Interpersonal Cognition and the Social Anxiety Scale for Adolescents. T-tests examined gender differences in interpersonal cognition, and chi-square tests examined adolescents’ appraisals of the likelihood of their own presentation anxiety and self as anxious. Girls more frequently reported positive, and less frequently reported negative, responses toward the depicted, anxious peer than boys. Also, a higher percentage of girls predicted that becoming anxious in the situation was likely, and non-acceptance of self as anxious was more frequent among girls. Boys predicted negative overt classmate reactions (e.g., laughing) towards the depicted, anxious peer, and towards themselves more frequently than did girls. Results are discussed in the context of gender-specific development and procedures for reducing adolescent social anxiety.
Risk of polysubstance use among sexual minority and heterosexual youth
Authors: Dermody Sarah
Published: November 2022

Background: Relative to heterosexual youth, sexual minority youth exhibit increased substance use. Risk for polysubstance use, which magnifies drug-related harms, remains largely unexamined for sexual minority youth. This investigation used a nationally-representative dataset to compare polysubstance use patterns between sexual minority and heterosexual youth. Methods: The cross-sectional 2015 CDC’s Youth Risk Behavior Surveillance System (N=15,624) was utilized. Latent mixture modeling empirically-identified subgroups of youth based on self-reported, past-month use of alcohol, cigarettes, chewing tobacco/snus/snuff, cigars/cigarillos/little cigars, e-cigarettes, marijuana, and past-month binge drinking (all dichotomized: 0 = none; 1 = at least once). Adjusting for race/ethnicity, sex, and age, the risk for being in each substance-using class was compared between youth who self-identified as heterosexual and gay/lesbian, bisexual, or “not sure.” Results: Five classes were supported: “non-users” (68.19%), “alcohol users” (13.08%; elevated alcohol use and binge drinking probabilities), “nicotine/marijuana co-users” (5.80%; elevated nicotine and marijuana use), “poly-substance/e-cigarette users” (5.34%; elevated on all substances except tobacco-containing products), and “polysubstance/tobacco users” (7.59%; elevated for all substances). Relative to heterosexual youth, gay/lesbian-identified youth were at risk of being “nicotine and marijuana co-users”, bisexual youth were at risk of being in all four substance-using classes, and the “not sure” youth were at risk of being “polysubstance/tobacco users.” Select disparities were larger for youth who were also female or minority race/ethnicity. Conclusions: Sexual minority youth, particularly bisexual youth, were at an increased risk relative to heterosexual youth for polysubstance use. Polysubstance use warrants attention in substance use interventions, including interventions tailored for sexual minority youth.

The authors’ own methodology of analysis is developed and the weighting factors of indicators of financial security of agriculture, industry, construction and transport, warehousing, postal and courier activities of Ukraine are evaluated. The structure of financial security of priority sectors of the national economy, i. e., the investment, credit, debt, monetary, production and economic, system-structural components is determined and the weighting factors of indicators are evaluated according to these security components. This approach made it possible to identify the indicators with a lesser extent along with the indicators with a greater extent of an impact they have on the general condition of subindexes, and therefore determine the overall level of financial-economic security of priority sectors of the national economy of Ukraine. The integral values of financial security of priority sectors of the national economy of Ukraine for 2010-2020 were computed. The results of the assessment allowed to identify, firstly, the state of financial security of the analyzed industries; secondly, the dynamic characteristics of changes in the level of financial security of priority sectors of the national economy; thirdly, the measure of differentiation in the state of financial security among the analyzed types of economic activity; fourthly, to form conclusions regarding the factors influencing the parameters of financial security of priority sectors of the national economy of Ukraine; fifthly, to determine the strategic directions and develop a set of the State policy instruments focused on strengthening financial security, taking into account the existing specifics for agriculture, industry, construction and transport, warehousing, postal and courier activities of Ukraine. Prospects for further scientific research in the analyzed sphere relate to the formation of recommendations regarding the linking of the results of the accomplished analysis with the formation of actions in the field of strengthening the financial-economic security of priority sectors of the Ukrainian economy.

Tarım, hayvancılık ve zanaatçılıkla gelişen dünya ekonomisine bugün internet tabanlı alt yapılar ve bilişim teknolojileriyle dijitalleşen bir iş yaşamı yön vermektedir. Endüstri devriminin beraberinde getirdiği bağımlı iş ilişkilerinin yerini dijital emeğin ve uzaktan çalışmanın almaya başladığı son çeyrek asırda çevrimiçi olunan yerin işyerine dönüştüğü, iş ilişkilerinin oturum açma ve kapama aralığında kurulduğu bir değişim sürecine tanıklık edilmektedir. Bu değişimin bir yönünü de iş yaşamında ayrımcılık, yıldırma, mobbing, taciz, zorbalık gibi vakaların dijitalleşen iş ilişkilerine yansımaları oluşturmaktadır. Bu çalışmada söz konusu yansıma alanlarından siber zorbalık olgusu dijitalleşen iş yaşamı odağında ele alınmaya çalışılmaktadır. Nitekim siber zorbalık çocuklar için olduğu gibi yetişkinler için de tehdit oluşturan, özel yaşamı olduğu kadar sosyal yaşamı ve iş yaşamını da doğrudan etkileyen bir sorunsaldır. Diğer yandan siber zorbalar sadece gerçek kişileri değil, tüzel kişileri de hedef alarak siber saldırılar gerçekleştirebilmektedir. Bu ise uzun yıllar emek ve özveri ile yaratılan kurumsal imajın, marka değerinin, ürün ve hizmetlerin kamuoyu nezdinde itibarsızlaştırılmasına neden olarak güven ve gelir kaybına sebebiyet verebilmektedir. Siber zorbalık ve iş yaşamı ilişkisinin hem kendi bağlamı içinde hem de neden-sonuç ilişkileri temelinde ele alınmaya çalışıldığı bu makalede siber zorbalıkla iş yaşamının dijitalleşen doğası çerçevesinde mücadele etmenin gerekliliği açıklanmaya çalışılmıştır. Siber etik ilkelerin ve siber nezaketin geleceğin iş yaşamı için bugünden inşa edilmesi gereken olgular olduğu vurgulanmıştır. İş yaşamında yüz yüze iletişimde olduğu gibi dijital etkileşimde de hoşgörüye, empatiye, şefkate ve nezakete alan açarak hareket etmenin, insan onur ve haysiyetine saygı temeline dayanan bir dijital kültür geliştirmenin yakın gelecek açısından belirleyici sonuçları olacağına dikkat çekilmiştir.

Al desarrollar este trabajo se consideró como propósito principal estudiar la dramatización pedagógica para optimizar el estadio cognoscitivo-emocional en estudiantes de Educación Física del Instituto Superior de Formación Docente Salomé Ureña (ISFODOSU), el cual se desarrolló durante el cuatrimestre 3-2021. La metodología aplicada fue un enfoque descriptivo transversal, basado en un componente de carácter cualitativo. La técnica de recolección de datos utilizada fueron los Test de Inteligencia Emocional y de Desarrollo Emocional. La población considerada fue de 289 estudiantes y la muestra fue de 14 estudiantes, todos de la Licenciatura en Educación Física. La organización y discriminación de la información fue realizada a través del programa Atlas. Ti. Los resultados obtenidos de los instrumentos indican que los estudiantes mostraron ciertas debilidades en lo cognitivo y en el manejo de las emociones en las actividades regulares de clases, cuya superación fue fortalecida en el desarrollo de la aplicación de la herramienta de dramatización. Se concluyó, mediante una caracterización de los hallazgos, que la dramatización constituye un recurso pedagógico adecuado para lograr el desarrollo del estadio emocional-cognitivo, en las diferentes dimensiones abordadas. Es una posibilidad didáctica y de acompañamiento en los procesos formativos.
Bias reduction in the logistic model parameters with the LogF(1,1) penalty under MAR assumption
Authors: Al-Shaaibi Muna , Wesonga Ronald
Published: November 2022

In this paper, we present a novel validated penalization method for bias reduction to estimate parameters for the logistic model when data are missing at random (MAR). Specific focus was given to address the data missingness problem among categorical model covariates. We penalize a logit log-likelihood with a novel prior distribution based on the family of the LogF(m,m) generalized distribution. The principle of expectation-maximization with weights was employed with the Louis' method to derive an information matrix, while a closed form for the exact bias was derived following the Cox and Snell's equation. A combination of simulation studies and real life data were used to validate the proposed method. Findings from the validation studies show that our model's standard errors are consistently lower than those derived from other bias reduction methods for the missing at random data mechanism. Consequently, we conclude that in most cases, our method's performance in parameter estimation is superior to the other classical methods for bias reduction when data are MAR.

This study collates compositional analysis of seaweeds data with information generated from in vitro gas production assays in the presence and absence of seaweeds. The aim was to assess and rank 27 native northern European seaweeds as potential feed ingredients for use to reduce methane emissions from ruminants. It provides information for use in future in vivo dietary trials concerning feed manipulation strategies to reduce CH4 emissions efficiently from domestic ruminants based on dietary seaweed supplementation. The seaweeds H. siliquosa and A. nodosum belonging to phylum Phaeophyta displayed the highest concentration of phlorotannins and antioxidant activity among the macroalgae giving anti-methanogenic effect in vitro, while this explanation was not valid for the observed reduction in methane when supplementing with C. filum and L. digitata in this study. D. carnosa and C. tenuicorne belonging to phylum Rhodophyta had the highest protein content among the macroalgae that reduced methane production in vitro. There were no obvious explanation from the compositional analysis conducted in this study to the reduced methane production in vitro when supplementing with U. lactuca belonging to phylum Chlorophyta. The strongest and most complete methane inhibition in vitro was observed when supplementing with Asparagopsis taxiformis that was used as a positive control in this study.

With high hardness, high thermal stability, chemical inertness and excellent optoelectronic properties, transparent hard and brittle materials have drawn significant attentions in frontier domains such as aerospace, photoelectric detection, and high-intensity lasers. Femtosecond laser processing technology demonstrates great potential for transparent hard and brittle materials processing due to its outstanding advantages such as non-contact, true 3D processing and programmable design. However, high-energy laser ablation usually causes severe damage to the surface of the materials, resulting in low processing accuracy, low processing efficiency and poor surface quality. Femtosecond laser hybrid processing strategies have been proven to be an effective solution to solve the above problems. This mini-review summarizes the fundamentals and research progress of femtosecond laser hybrid processing strategies of transparent hard and brittle materials in recent years. Moreover, the challenges and application prospects of these techniques are discussed.
