Adiestramiento del búfalo (Bubalus bubalis) como animal de trabajo
Authors: Cely Vásquez Juan David , Plazas Borrero Camilo Hernando
Published: July 2021

En regiones de Asia y Suramérica, el búfalo (Bubalus bubalis) se ha venido utilizando desde siglos atrás para brindar fuerza de trabajo, en las modalidades de carga, tiro o monta, e incluso en la mecanización de suelos con características de inundación (cultivos de arroz), en donde el lodo puede llegar a una profundidad que alcanza 40 a 60 cm, se pueden desplazar a una velocidad de 6-8 km/h, y pueden llegar a mover cargas de hasta 1500 kg, con rendimiento de trabajo de 0.25 hectáreas por día. También se observado que la fuerza ejercida por los búfalos como animales de trabajo no representa restricciones al utilizarlos en diferentes labores agropecuarias dentro de las fincas, y su clara adaptación al trópico permite un desarrollo físico adecuado, facilitando su entrenamiento. Se considera como una “tecnología apropiada”, el sistema que emplea la combinación de remolque y búfalo, porque sobrepasa la efectividad de la maquinaria en productividad y costos de funcionamiento, lo cual ha generado que, en las plantaciones de palma en el momento de la cosecha, los búfalos sean utilizados como principal fuente de tracción de los remolques que almacenaran este fruto. A pesar de la existencia de zonas ganaderas y productoras de palma africana, en Colombia no se han documentado estudios donde se relacionen los procesos de adiestramiento del búfalo mediante la implementación de doma racional, para utilizarlos como animales de trabajo, por lo cual, el objetivo de este trabajo es exponer las cualidades de esta especie, y las técnicas adecuadas para el adiestramiento y manejo de los búfalos destinados para trabajo, con base en su etología y trato racional. Se ha reconocido que los implementos e instalaciones utilizados en el manejo de los búfalos son importantes para facilitar el adiestramiento, los cuales deben ser confortables en caso de la sujeción de la cabeza, en la nariz se utiliza argolla nariguera, también se usan lazos de distintos calibres y un cabezal, pero en ningún caso se debe infringir daño; en actividades de trabajo se utiliza el sillín, la alfombra y el remolque, los cuales no deben limitar la locomoción del búfalo. A diario y durante el ordeño es necesario dedicar de 20 a 30 minutos a la manipulación del bucerro para tener contacto y establecer un vínculo con la persona que lo está entrenando. Para permitir un control y poder guiar al animal, en esta etapa se le enseña algunas órdenes con el lazo pisador y con la voz, halándolo de la cuerda del cabezal atado a la argolla nariguera; los búfalos se deben ejercitar mediante caminatas entre una a dos horas. En el sitio de trabajo se guía al animal, siempre con el amansador por delante para mostrarle los caminos y enseñarle cuales son las calles; este acompañamiento puede variar en cuanto al tiempo de duración, porque con algunos búfalos puede tomar meses y en otros menos, en general se hace el refuerzo de órdenes de voz hasta llevar el animal a trabajar con una sola persona.

Background/Aim. The materials used nowadays for bone replacement do not fully meet the requirements for complete regeneration, which is why new ones are being tested. Despite numerous attempts to improve bone tissue regeneration, no fulfilling material has been found yet. This study investigated the influence of poly-lactide-co-glycolide (PLGA) and polyethyleneimine (PEI) as coatings for hydroxyapatite (HAP) bone carriers on bone tissue regenerative potential in rabbits? calvarial defect. Methods. Calvarial defects measuring 6 mm in diameter were made in 19 skeletally mature rabbits. Defects were filled with one of the following materials: PLGA coated HAP (HAP + PLGA), PEI coated HAP (HAP + PEI), and bovine HAP ? Bio-Oss? (positive control). Unfilled defects represented negative control. Histological analysis was performed in order to determine the inflammatory response of the host tissue. The formation of the new bone was evaluated using histomorphometric analysis. All analyses have been conducted in samples obtained 3, 6, and 9 weeks after implantation. Results. Three weeks post-implantation, a trend toward increased healing in the HAP + PLGA group compared to other investigated materials was noticed, with no statistically significant difference between the study groups (p > 0.05). However, after 6 and 9 weeks, significant healing was observed in favor of the HAP coated with PLGA compared to other groups (p < 0.05). Within this group, greater bone healing was observed compared to the HAP + PEI and Bio-Oss? groups. Conclusion. PLGA demonstrated greater coating potential compared to PEI with respect to osteogenesis improvement in bone reconstructive surgery.

Authors: Beljic-Ivanovic Katarina , Karadzic Branislav
Published: July 2021

Background/Aim. Maxillary first molars are one of the most challenging teeth for endodontic therapy. There are certain disparities in the number of roots and canals and canal interrelationships within the same root, particularly those with fused roots. The aim of the study was to assess ex vivo features of roots, root canals, and canal walls in maxillary first molars with fused roots. Methods. Out of the total of 366 maxillary first molars, 64 extracted maxillary first molars with fused roots were included in the study using cone-beam computed tomographic and microscopic examining. Tooth dimensions at the level of pulp chamber floor, number, location and distance between orifices, number and canal morphology, canal wall thickness, and features of apical foramina were examined and measured. Results. The incidence of maxillary first molars with root fusion was 17.5%, of which 60.0% was palatal fused to distobuccal root. At the level of the pulp chamber floor, the bucco-palatal dimension was significantly larger at 10.4 mm than M-D with 7.0 mm. Four canal orifices were detected in 65.6%, with the shortest distance of 1.95 mm between MB1 and MB2. In fused roots, two or three canals most frequently correlated strongly with the number of major apical foramina. No fusion of canals was found in fused roots. The thinnest canal wall in the mesiobuccal and distobuccal fused root was mesial with 1.25 mm, and distal with 1.31 mm, while for the palatal root, the thinnest was the palatal wall with 1.97 mm. Two or three large apex foramina were registered with a significant correlation with the number of canals in the fused root. Conclusion. The most frequent type of fusion was between the palatal and distobuccal roots. Bucco-palatal dimension at the level of the pulp chamber floor was significantly larger than the mesiodistal, with the shortest inter-orifice distance between the MB1 and MB2 orifice. The number of canals was either two or three, coinciding with the number of major apical foramina. There was no fusion of the canals in fused roots. The thinnest canal wall was either mesial or distal.
The measurement of venous pressure by Doppler: is it a hemodynamic evaluation ?
Authors: Antignani Pier Luigi , Peruzzi Giampiero , Spina Tommaso
Published: July 2021

Since 1980 using the Doppler method, planned by Bartolo, we have studied several patients by means of the measurement of venous pressures, both in orthostatism and in clinostatism. In a normal subject, in orthostatism the value of average pressure is 60 mmHg in the posterior tibial vein, and 60 mmHg in the long saphenous vein. When there are varicose veins, the average pressure is 90 and 96 mmHg respectively in the deep veins and in the superficial ones. In the case of post-thrombotic syndrome, the average values are 101 and 102 mmHg in the deep and superficial veins, respectively. In clinostatism, the normal values are under 20 mmHg and in subjects with vein thrombosis the value increase to 30 mmHg and more. After more than 30 years we discuss the reliability of the method, the hemodynamic basis and its clinical application in phlebological practice.

Financial impact of using EUR call options to hedge accounts receivables
Authors:   Grace College, School of Business Winona Lake Indiana, USA, McEwan Dr. Kenneth B.
Published: July 2021

International business has grown rapidly in recent years as companies seek to take advantage of expanding supply chain opportunities. As companies enter into contracts to take advantage of engineering, production, and cost reduction capabilities of the global supply chain, they may be creating a foreign currency exchange rate risk. The quantitative study examined the 60-day EUR/USD exchange rate fluctuation and the use of currency call options to hedge the risk associated with EUR/USD currency fluctuations. The researcher analyzed 13 years of historical EUR/USD currency data and 10 years of actual EUR call options premiums for this research paper. The researcher concluded that the variability of the EUR/USD over 60-days does pose financial risk to a company. The study also found that using currency call options to hedge this 60-day exchange rate risk resulted in an overall transactional financial loss as compared to no hedging. However, research studies have shown that the use of hedging instruments to smooth financial results may result in lower overall financing costs which could offset the hedging transactional costs. This study did not address the benefits of the use of hedging to smooth financial results or obtain other related financial benefits. The researcher recommends that a firm should recognize the exchange rate risks it may be establishing within 60-day EUR or USD payable contracts and develop an appropriate hedging strategy.

Authors:   Medgar Evers College, City University of New York Department of Computer Information Systems, New York, USA, Ahn David
Published: July 2021

The unprecedented COVID-19 global pandemic radically changed the way we do things. The face mask is now a must to put on, and you do not handshake anyone. We are not even allowed to go near any person within six feet to maintain social distancing. The sudden pandemic lockdown forced all face-to-face classes into online classes overnight. It added immense pressure and stress to both instructors and students that brought many negative consequences. The sustained disruption has challenged higher education institutions to maintain academic continuity and put them into a grave financial situation due to a substantial decline in cash flow. This paper presents a case study of the transition to online learning for the Computer Information Systems classes at Medgar Evers College during the COVID-19 pandemic lockdown. We present the method we used to maintain academic continuity, examine the challenges of abrupt online transition, and assess what we learned from its outcome. In conclusion, we discuss the threats and opportunities for higher education institutions in the post-pandemic, which might change the entire landscape of higher education.

Automated Complexity Assessment of English Informational Texts for EFL Pre-service Teachers and Translators
Authors: Parashchuk Valentyna , Yarova Laryssa , Parashchuk Stepan
Published: July 2021

Automated text complexity assessment tools are of enormous practical value in solving the time-consuming task of analyzing English informational texts for their complexity at the pre-reading stage. The present study depicts the application of the automated text analysis system the TextEvaluator as an effective tool that helps analyze texts on eight dimensions of text complexity as follows: syntactic complexity; academic vocabulary; word unfamiliarity; word concreteness; lexical cohesion; interactive style; level of argumentation; degree of narrativity, with further summarizing them with an overall genre-dependent complexity score. This research examines the complexity dimensions of English informational texts of four genres – legal, linguistic, news, and medical – that are used for teaching reading comprehension to EFL (English as a foreign language) pre-service teachers and translators at universities in Ukraine. The data obtained with the help of the TextEvaluator has shown that English legal texts are the most difficult for reading comprehension in comparison to linguistic, news, and medical texts. In contrast, medical texts are the least challenging out of the four genres compared. The TextEvaluator has provided insight into the complexity of English informational texts across their different genres that would be useful for assembling the corpora of reading passages scaled on specific dimensions of text complexity that predict text difficulty to EFL pre-service teachers and translators.

Published: July 2021

The study explores students’ perspectives towards virtual classes and the impact of such classes on EFL learners’ communication skills. Such study is valuable due to the lack of research works that investigate EFL students’ attitudes towards the effectiveness of such classes. Also, the findings can substantially improve the Saudi virtual education. Regarding the questions of the study, it answers two main questions: What are EFL learners’ attitudes towards virtual classes? What is the impact of virtual classes on EFL learners’ communication skills from students’ perspectives? To achieve the objectives of this study, a questionnaire was administered to 50 EFL students of levels seven and eight in English Department at the College of Sciences and Humanities at Prince Sattam Bin Abdulaziz University. The findings indicated that students had positive attitudes toward virtual classrooms. Such classes could enhance their communication, and improve their technical and self-learning skills. Based on these results, some recommendations were suggested that could be taken into consideration in future studies. First, further studies should be done to investigate the impact of virtual classes on other science classes such as Chemistry and Medicine in the COVID- 19 period. Second, such study should be conducted with a different sample of students (male). Finally, the same research can be applied to faculty members to explore their attitudes toward virtual education and its effect on communication skills.
Multimodality and Digital Narrative in Teaching a Foreign Language
Authors: Fedorenko Svitlana , Voloshchuk Iryna , Sharanova Yuliia , Glinka Nataliia , Zhurba Kateryna
Published: July 2021

The article focuses on the authors’ pedagogical experience of exploiting digital narratives in a foreign language education at a modern university (on the basis of National Technical University of Ukraine “KPI” named after Igor Sikorsky). The study aims to consider multimodality in terms of foreign language didactics. It was designed by the constructivism theory and narratology in terms of teaching a foreign language. The research exploited the set of theoretical methods: analyzing, summarizing, and interpreting scholarly sources on the issue under scrutiny; generalization and conceptualization of the authors’ pedagogical experience. Applying those methods in coherence logic enabled the effective study and interpretation of the concepts of “narrative” and “digital narrative” in their interrelations. In the study, the narrative is viewed as a sociocultural tool that provides students with deeper self-understanding, and complements the communicative system of foreign language acquisition with metacognition and values of life meaning. The digital narrative as a form of expression, empowered and determined by digital technologies incorporates multimodal communication and narrative as a cognitive unity. The authors have stated that multimodality, grounded on information technologies, is introducing entirely new semiotic resources into the communicative environment of foreign language learning. It is also generating innovative ways and forms of oral and written interaction. Multimodal learning activities illustrating the specifics of creating digital narratives by learners of English as a foreign language, are highlighted. The significance of the study lies in the fact that the ongoing COVID-19 pandemic is unquestionably a rather fertile condition for active implementing digital technologies into foreign language education, and developing different multimodal learning activities in this area

The shift from in-person to remote learning has have led to crisis management. Teachers find it more challenging as content designing and presentation have to undergo drastic change. Though many face-to-face methodologies could be adapted in the online context, Yet, “one size fits all approach” cannot be standardized in remote learning setups. The critical challenge in this ‘new era’ is to make the learners motivated, productive, and responsible. The study aims to find the impact of four digital tools: Discussion Forums, Kahoot, Padlet, and FlipGrid in fostering 21st-century skills and identify the existing gaps between Remote Learning and instructional activities in the EFL context. The study adopts a quantitative approach. First, it tries to examine the utilization of the digital learning tools under Blackboard by the faculty at the Department of English at Prince Sattam University and find out the impact of digital tools in fostering 21st-century skills on the undergraduate students pursuing level six. From the results of the study, it is evident that digital learning tools empower learners. The study recommends significant changes in the pedagogies. Finally, the study suggests rubrics be taken into consideration while choosing digital tools to foster 21 st century skills.

Published: July 2021

The application of technology in education has become a significant option for a more efficient and interactive approach, particularly in language teaching. However, few studies have investigated the use of technology in the teaching of writing in English language classrooms, especially in the Malaysian context. The present study investigates the teaching of writing practices and technology tools employed by English as a second language teachers when teaching writing skills. Using Technology Acceptance Model as the underpinning theory, this study also examines the effectiveness of the use of technology in the teaching of writing by collecting data from forty secondary school English teachers in Malaysia using a set of questionnaires. The findings indicated that technology is an important tool to improve students’ writing skills, assist teachers as a teaching aid and promote student engagement in the classroom. However, the lack of technical support hinders some teachers from using technology because it takes a lot of time which disrupts the teaching and learning process. Nevertheless, there is no doubt that technology plays an important role in helping teachers to improve students’ writing skills. Significantly, the findings of this study provide evidence to improve the application of technology in language teaching and learning.

METHOD OF STEPWISE SMOOTHING EXPERIMENTAL DEPENDENCES FOR PROBLEMS OF SHORT-TERM FORECASTING
Authors: Ermakov Anatoly Anatolevich , Kirillova Tatyana Klimentyevna
Published: July 2021

The article considers the correspondence of the step-by-step smoothing method as one of the possible algorithms for short-term forecasting of statistics of equal-current measurements of monotone functions, which represent the values of the determining parameters that evaluate the dynamics of the states of complex technical systems based on the operating time. The true value of the monitored parameter is considered unknown, and the processed measurement values are distributed normally. The measurements are processed by step-by-step smoothing. As a result of processing, a new statistic is formed, which is a forecast statistic, each value of which is a half-sum of the measurement itself and the so-called private forecast. First, the forecasts obtained in this way prove to have the same distribution law as the distribution law of a sample of equally accurate measurements. Second, the forecast trend should be the same as the measurement trend and correspond to the theoretical trend, that is, the true values of the monotone function. Third, the variance of the obtained statistics should not exceed the variance of the original sample. It is inferred that the method of step-by-step smoothing method can be proposed for short-term forecasting

Authors: González Romero Martín Humberto
Published: July 2021

Con base en algunos documentos y testimonios de las agrupaciones que conformaron el Movimiento de Liberación Homosexual en México durante sus primeros años, así como en el análisis de la prensa, esta investigación da cuenta de las estrategias para involucrar a los sectores populares de travestis en la movilización urbana. Particularmente, sigue las acciones del Frente Homosexual de Acción Revolucionaria (fhar), el cual consideró que la práctica del travestismo era una parte central de su noción de liberación homosexual y que resultaba esencial en su compromiso político con las clases populares. El análisis de las controversias desatadas por las estrategias travestis del fhar da cuenta de la relación entre la moderna identidad gay y un amplio abanico de identidades trans. Así, este relato permite situar a la historia de la liberación homosexual dentro de una historia queer del pasado reciente en México.

Published: July 2021

Brazil began to explore its seas in the 60’s of the XX Century looking for petroleum. This journey began in the Northeast and the first oil field produced offshore was the Guaricema Field, in the State of Sergipe. During the 70’s, Petrobrás found oil in the Campos Basin, between the States of Espírito Santo and Rio de Janeiro, that became the most important oil province in Brazil until the discovery of the Pre-Salt province, in the Santos Basin. As these fields are producing for a long time, many of them are already completely depleted or their production is in way of to be not commercial anymore, and their facilities need to be decommissioned. This review of decommissioning practices of fixed offshore platforms carried out worldwide has focus on the removal of topside with special vessels designed for this purpose or with conventional methods (crane vessels + barge). It will show the benefits of using specialised heavy lift vessels to remove the topsides and move it to shore for dismantling / recycling / reuse / disposal. The cases for study were the successful decommissioning projects in the North Sea: Brent B/D, Valhall QP, Viking, Curlew, Eider A, Golden Eye and Leman, Iwaki-Oki, Halfweg Q1, Yme and Ninian North.

Published: July 2021

ABSTRACT The use of hydroxyapatite (HAp) based on Aceh's bovine bone has been studied as a candidate for thecoating dental implant materials. In this study, the effect of sintering temperature and viscosity on the thickness ofthe hydroxyapatite layer on the 316L stainless steel plaque was observed. The hydroxyapatite was synthesized frombovine bone and then coated on the plate using the dip-coating method. Then, the plate surface was dried at 110 ºCfor 30 minutes and sintered with various temperatures of 500, 600, 700, and 800 ºC for 1 hour. The plate that hasbeen coated with hydroxyapatite was characterized using a thickness meter to measure the thicknesses of the layer.The water composition of 10 grams/L had a better effect on the thickness of the implant material coated with HApbeef bone compared to the water composition of 4, 6, and 8 (gram/L) (p0.05). On the other hand, the temperaturefactor did not affect changes in the thickness of the implant material (p0.05). The higher water composition (10grams/L) resulted in a decrease in the thickness of the implant material coated with beef bone HAp.

Abstract. The Covid-19 pandemic in early 2020 had a wide impact on all aspects of human life, with activity restrictions aimed at stopping the spread of the Coronavirus. Activity restrictions are widely applied in every place to cut off the transmission of the Coronavirus. The restrictions affect the information dissemination on cultural heritage, such as socialization, exhibitions, seminars, and others that can not be done directly. Due to the restrictions, a site visit to the museum and historical sites is hard to do. The utilization of new media needs to be considered to disseminate cultural heritage information virtually.  This study aims to acknowledge the role of new media for information dissemination during the pandemic and its benefits to the community. Data were collected from internet sources and questionnaires followed by respondents using the Google Form platform shared through WhatsApp. The results found out that the new media can provide solutions in cultural heritage dissemination virtually. This new method also provides knowledge and experiences in learning to recognize cultural heritage in this period.

This study aims to measure the benefits of edmodo application, in the Islamic Elementary School of Cikal Harapan I BSD. Teachers are given alternative edmodo applications to be used in the development of training models, as an answer to the problem of how to improve development models in the midst of their busy activities. By using the edmodo application, teachers in the Islamic Elementary School of Cikal Harapan I BSD can improve pedegogical competence through the edmodo application-based training they use. Although everyday teachers are accompanied by modern communication tools such as smartphones, computers and laptops, it is not easy to use new methods. Patience and perseverance are needed to introduce this model development model, especially the introduction of each edmodo application feature, active interaction when given training material as well as their seriousness to improve skills in using the edmodo application. In addition to practicing the use of edmodo applications in 42 teachers, they also gave questionnaires. Data in the field is inputted with the SPSS program which provides an overview of the level of teacher acceptance of the use of the edmodo application. Of the 42 teachers who were the subjects of the study, there were 50 percent who could ultimately benefit from using the Edmodo application. The rest is split in constraints due to time constraints, incompatible devices and difficulty understanding edmodo's application features.

Анотація. Пропонована публікація присвячена аналізу нововіднайденого підпільного документа «Загальна характеристика з життя Бориславського басейну» про повсякденне життя Дрогобиччини у 1945–1946 рр. Мета статті – проаналізувати та опублікувати документ із історії повсякденного життя мешканців Дрогобиччини 1945–1946 рр. Методологія дослідження – базується на принципах історизму, науковості, об’єктивності, при цьому застосовуються методи зовнішньої та внутрішньої критики джерел. Наукова новизна полягає у тому, що до наукового обігу вперше вводиться нововіднайдений документ про повсякденне життя на Дрогобиччині (1945–1946) та проводиться його аналіз. Висновки. Отже, публікований документ «Загальна характеристика з життя Бориславського басейну», був знайдений у лісі біля села Стратин та зберігається в Архіві Центру досліджень визвольного руху. У документі подається характеристика різноманітних сфер суспільного життя на території Борислава, Дрогобича, Стебника, Східниці, Трускавця, Тустанович (тепер частина м. Борислав) у 1945–1946 рр. (хоча точна дата його укладення невідома). Документ укладений очевидно підпільником на псевдо «Улас». Водночас відомо, що у 1946–1947 рр. Петро Петрига-«Улас» працював референтом пропаганди, а відтак провідником Дрогобицького надрайонного проводу ОУН (10.1946–07.1947). Матеріал автор структурував на двадцять п’ять рубрик. Публікований документ є важливим джерелом до характеристики історії повсякденного життя перших післявоєнних років як Дрогобиччини, так і Західної України загалом. Документ публікується мовою оригіналу відповідно до сучасних археографічних вимог.
СПОГАДИ ПРО ДЕПОРТАЦІЇ ЯК ВАЖЛИВЕ ДЖЕРЕЛО ДО ВИВЧЕННЯ ПОВОЄННОЇ ТРАГЕДІЇ УКРАЇНСТВА
Authors: Сергійчук Володимир
Published: July 2021

Анотація. Мета дослідження – звернути увагу при дослідженні депортаційних процесів із західноукраїнських земель після Другої світової війни на спогади сучасників і безпосередніх учасників подій з огляду на обмеженість документальних свідчень національно-визвольного руху й необ’єктивність матеріалів комуністичної влади. Методологія дослідження ґрунтується на принципах історизму, системності, науковості, верифікації, авторської об՚єктивності, на використанні загальнонаукових (аналіз, синтез, узагальнення) та спеціально-історичних (історико-генетичний, історико-типологічний, історико-системний) методів. Наукова новизна полягає у тому, що на основі аналізу первинних документів українського національно-визвольного руху й спогадів депортованих, які вдалося записати в основному в умовах незалежної України, з’явилася можливість скласти більш цілісну картину тих далеких подій, відгранити особливості історичних процесів. При цьому акцентується увага на тому, що жорстокість депортаційних акцій проявлялася на всіх теренах західноукраїнського розселення – від Збруча до Вісли, про що засвідчують спомини виселюваних мешканців Буковини, Волині, Галичини, Лемківщини, Надсяння, Холмщини й Підляшшя. Також відзначається роль у записах споминів священників Української греко-католицької церкви, особливо Апостольського візитатора в Центральній Азії о. Василя Говори, а також журналіста газети «Наше слово» у Варшаві Богдана Гука. Висновки. Використання споминів очевидців подій і депортованих із західноукраїнських земель після Другої світової війни дає можливість створити цілісну картину тих трагічних подій, а в окремих випадках і повністю її відтворити.
Surfboard Paddling Technique and Neuromechanical Control: A Narrative Review
Authors: Volschenk Wynand , Crowley-McHattan Zachary , Whitting John , Meir Rudi , McKenzie Alec
Published: July 2021

Surfboard paddling is an essential activity when surfing. Research investigating surfboard paddling, especially as it pertains to neuromechanical control and techniques used, is limited. Previous research made use of swim ergometers to examine surfboard paddling demands. The validity of using swim ergometers in surfboard paddling research and training deserves further analysis. To establish ecologically valid findings, researchers have begun to use swim flumes and still-water paddling environments to investigate paddling efficiency and technique. This emerging body of research has reported that muscle activation patterns, intensities, and timings differ as surfers move through different paddle stroke phases. A deeper understanding of paddling's neuromechanical control may help enhance the understanding of how to improve paddle performance and perhaps reduce injury risk. Therefore, the purpose of this review was to identify the gaps in the existing literature to help identify future research directions in relation to surfboard paddling techniques and neuromechanical control.
SOLIDARITY CHECK IN TIMES OF COVID-19. ANALYSIS OF THE EU APPROACH TOWARDS ITS CLOSEST NEIGHBOURS WITH A SPECIAL FOCUS ON MONTENEGRO
Authors: Đurić Stefan , Lalatović Bojana
Published: July 2021

Solidarity as one of the cornerstone values of the European Union has been once again seated on the red chair and intensively discussed within the European Union and broader. After the economic recession and migrant crisis that marked the last two decades, the outbreak of the COVID-19 pandemic has once again harshly tested the fundamental objectives and values of the European Union and the responsiveness and effectiveness of its governance system on many fronts. In April, 2020 several EU Member States were among the worst affected countries worldwide and this situation soon became similar in their closest neighbourhood. It put a huge pressure on the EU to act faster, while at the same time placing this sui generis community to the test that led to revealing its strengths and weaknesses. As it happened in the previous crises, the Union launched policies and various programmes that were meant to lessen the burden of the Member States and aspiring countries caused by the crises. The objectives of the mentioned soft law instruments that the EU adopted during the COVID-19 crisis has been not only to show that EU law is equipped to react to health and economic crises rapidly but to deliver its support in terms of solidarity to its Member States and its closest neighbours facing the unprecedented health and economic crisis. This article will explore the value and implication of the solidarity principle in times of Covid-19 in its various manifestations. A special focus will be on the financial and material aspects of the EU instruments created to combat the negative consequences of the pandemic and their further impact on shaping the solidarity principle within the EU system. While examining the character and types of these mechanisms a special focus will be placed on those available to Western Balkan countries, whereas Montenegro as the “fast runner” in the EU integration process will be taken as a case study for the purpose of more detailed analyses. One of the major conclusions of the paper will be that although the speed of the EU reactions due to highly complex structure of decision making was not always satisfying for all the actors concerned, the EU once again has shown that it is reliable and that it treats the Western Balkan countries as privileged partners all for the sake of ending pandemic and launching the socio-economic recovery of the Western Balkans. Analytical and comparative methods will be dominantly relied upon throughout the paper. This will allow the authors to draw the main conclusions of the paper and assess the degree of solidarity as well as the effectiveness of the existing EU instruments that are available to Montenegro and aimed at diminishing negative consequences of the crisis.
