Published: February 2021

Background
Ghana confirmed the first two cases of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS CoV-2) infection on 12th March 2020. Following this, the government introduced routine and enhanced contact tracing to identify, quarantine, and test contacts for COVID-19. This study, therefore, intends to document the experiences of contact tracers, their supervisors, during COVID-19 containment in Ghana.

Methods
Purposive sampling was used to select twenty-seven (27) participants; sixteen contact tracers, six supervisors, and five contacts of COVID-19 cases for an in-depth interview using a topic guide. These interviews were conducted on a phone or face-to-face basis whilst maintaining physical distancing protocol. All these were recorded and transcribed verbatim. Then, QSR NVivo 12 was used to analyse the data thematically.

Results
Contact tracers were selected based on their professional background and surveillance experience with other infectious diseases. They were trained before the first confirmed cases of COVID-19 in the country and before deployment. Deployment of contact tracers was in pairs to monitor contacts daily through physical visits or over the phone. Their activities included educating contacts about the condition, filling the symptoms diary, and providing psychological support. Contacts for COVID-19 were identified through case investigation, and their monitoring is done once a day despite the twice-daily requirement. Wherever a case was confirmed, enhanced contact tracing within a 2km radius was done. Furthermore, it was reported that some contacts were not adhering to the self-quarantine. In addition to this, other challenges included; unstable provision of PPEs and remuneration, refusal of some contact to test, delays in receiving test results, and poor coordination of the whole process.

Conclusions
The study concludes that contact tracing was generally perceived to be helpful in COVID-19 containment in Ghana. However, adhering to self-quarantine protocol had many challenges for both contact tracers and the contacts. Improving coordination and quick release of test results to contacts is necessary for COVID-19 containment. Lastly, the supply of Personal Protection Equipment and motivation needs to be addressed to help position the country well for effective contact tracing.
Small-sided games: An umbrella review of systematic reviews and meta-analyses
Authors: Clemente Filipe Manuel , Afonso José , Sarmento Hugo 
Published: February 2021

ObjectiveThis umbrella review was conducted to summarize the evidence and qualify the methodological quality of SR and SRMA published on small-sided games in team ball sports.MethodsA systematic review of Web of Science, PubMed, Cochrane Library, Scopus, and SPORTDiscus databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.ResultsFrom the 176 studies initially identified, 12 (eight SR and four SRMA) were fully reviewed, and their outcome measures were extracted and analyzed. Methodological quality (with the use of AMSTAR-2) revealed that seven reviews had low quality and five had critically low quality. Two major types of effects of SSGs were observed: (i) short-term acute effects and (ii) long-term adaptations. Four broad dimensions of analysis were found: (i) physiological demands (internal load); (ii) physical demands (external load) or fitness status; (iii) technical actions; and (iv) tactical behavior and collective organization. The psychological domain was reduced to an analysis of enjoyment. The main findings from this umbrella review revealed that SSGs present positive effects in improving aerobic capacity and tactical/technical behaviors, while neuromuscular adaptations present more heterogeneous findings. Factors such as sex, age group, expertise, skill level, or fitness status are also determinants of some acute effects and adaptations.ConclusionThe current umbrella review allowed to identify that most of the systematic review and meta-analysis conducted in SSGs presents low methodological quality considering the standards. Most of the systematic reviews included in this umbrella revealed that task constraints significantly change the acute responses in exercise, while SSGs are effective in improving aerobic capacity. Future original studies in this topic should improve the methodological quality and improve the experimental study designs for assessing changes in tactical/technical skills.

The MOMENTUM project deals with the new 5G mobile technology and explores how they contribute to an improvement in emergency care. Different applications, as well as various technical and clinical aspects, including IT security, are considered. Integrated emergency care seems sensible, particularly for emergencies outside of metropolitan areas and for particularly critical cases.
Manual versus Automatic Classification of Laryngeal Lesions based on Vascular Patterns in CE+NBI Images
Authors: Esmaeili Nazila , Illanes Alfredo , Boese Axel , Davaris Nikolaos , Arens Christoph , Navab Nassir , Friebe Michael 
Published: February 2021

Abstract
Longitudinal and perpendicular changes in the blood vessels of the vocal fold have been related to the advancement from benign to malignant laryngeal cancer stages. The combination of Contact Endoscopy (CE) and Narrow Band Imaging (NBI) provides intraoperative realtime visualization of vascular pattern in Larynx. The evaluation of these vascular patterns in CE+NBI images is a subjective process leading to differentiation difficulty and subjectivity between benign and malignant lesions. The main objective of this work is to compare multi-observer classification versus automatic classification of laryngeal lesions. Six clinicians visually classified CE+NBI images into benign and malignant lesions. For the automatic classification of CE+NBI images, we used an algorithm based on characterizing the level of the vessel’s disorder. The results of the manual classification showed that there is no objective interpretation, leading to difficulties to visually distinguish between benign and malignant lesions. The results of the automatic classification of CE+NBI images on the other hand showed the capability of the algorithm to solve these issues. Based on the observed results we believe that, the automatic approach could be a valuable tool to assist clinicians to classifying laryngeal lesions.
Wearable motion sensors and digital biomarkers in stroke rehabilitation
Authors: Derungs Adrian , Schuster-Amft Corina , Amft Oliver 
Published: February 2021

Abstract
We propose three novel digital biomarkers for the longitudinal performance monitoring and movement evaluation of hemiparetic patients, e.g. after stroke. We devised convergence points (CP) for the bilateral walking analysis based on gait parameters, e.g. stride duration using regression- modelling to estimate similarity between body sides. The physical activity (PA) was devised to evaluate the energy expenditure of all extremities during training and free-living. The functional range of motion (fROM) is a digital biomarker to quantify the upper arm reaching ability, represented in 3D visualisations. In this work, we detail CP, PA, and fROM to derive rehabilitation insights for personalising therapies. We evaluated the proposed digital biomarkers in a clinical observation study with 11 patients after stroke during their rehabilitation including therapy and self-paced daily routines.

Published: February 2021

Abstract
Surgical tool recognition is a key task to analyze surgical workflow, in order to improve the efficiency and safety of laparoscopic surgeries. The laparoscopic videos are important sources to conduct this task, However, there are some challenges to analyze these videos. Focus on the imbalanced dataset problem, data augmentation method based on generate different synthetic datasets and evaluate their performance training on a convolutional neural network model are investigated in this research. The results show the effect on the model with different background patterns. A better performance was achieved when the model was trained by a structure background dataset. Further research will be needed to understand why the original background patterns support the correct classification. It is assumed that this is an overlearning effect, that will not hold if other procedures were included into the test set.
Recounting the Empowerment of Women in Rural Areas of KwaZulu-Natal from Information and Knowledge in the Fourth Industrial Revolution Era
Authors: Jiyane Glenrose 
Published: February 2021

Abstract
The fourth industrial revolution (4IR) marks the new, advanced era of development in humankind, and globally countries are in the process of ensuring their citizenry’s readiness. In South Africa, various governmental departments, organizations, non-governmental organizations (NGOs) and non-profit organisations (NPOs) are making efforts, through their plans, talks and actions, to attain this status for all her people, particularly women in rural areas. However, the development of women in the rural areas for empowerment remains a concern in developing countries. Consequently, there is a dire need to ensure the developmental status for women in rural areas in the advent of the 4IR, and this paper seeks to demonstrate that information and knowledge may be instrumental in empowering women in rural areas to strive in the 4IR. Accordingly, information and knowledge are a critical resource contributing to the empowerment of women in rural areas for their development. An exploratory question is raised to determine whether South Africa is ready for Fourth Industrial Revolution. The outcome of this paper will contribute to the body of knowledge advocating the importance of information and knowledge in the empowerment of women in rural areas. Significantly, it will generate insights for policymakers on the important role of information and knowledge for women’s development.
On the absorption probabilities and mean time for absorption for discrete Markov chains
Authors: Halidias Nikolaos 
Published: February 2021

Abstract
In this note we study the probability and the
mean time for absorption for discrete time Markov chains. In particular, we are
interested in estimating the mean time for absorption when
absorption is not certain and connect it with some other known
results. Computing a suitable probability generating function, we are able to estimate the mean time for absorption when absorption is not certain giving some applications concerning the random walk. Furthermore, we investigate the probability for a Markov chain to reach a set A before reach B generalizing this result for a sequence of sets

Esplendor de Portugal, oscuridad de Angola: la historia desde la memoria
Authors: Aguilar González Luz Eugenia , Margarito Gaspar Mayra 
Published: February 2021

El trabajo analiza la novela Esplendor de Portugal,de António Lobo Antunes. Se analiza la forma como, a través del proceso de ficcionalización, la historia de la independencia de Angola y el regreso de los portugueses a Lisboa (retornados) es una metáfora del derrumbe colonial (la historia) mostrado desde la subjetividad de los personajes (la memoria). El análisis de las estrategias de ficcionalización permiten demostrar que la novela no es histórica, sino intimista.
Se analizan las estructuras narrativas, discursivas y temáticas con base en la teoría de los mundos posibles y los conceptos de cronotopo y polifonía de Bajtin. El análisis histórico permite establecer el eje que estructura los acontecimientos de la novela y a la vez, permite comprender la forma en que los sucesos históricos se resignifican para construir un mundo literario.
Como conclusiones encontramos que los mecanismos de ficcionalización y estéticos se basan en la memoria y los tiempos, real e interno, de los personajes, lo que deriva en la deslocalización psíquica y espacial de estos. Ello se manifiesta por medio de la pérdida de la identidad de los retornados, la fragmentación discursiva y temporal de la historia y la memoria delirante de los personajes. El lenguaje se caracteriza por la abundancia de metáforas, tematizaciones, diálogos y estrategias tipográficas que contrastan con lo sórdido del tema de la novela, lo cual logra un equilibrio estético.
Reproducción y lucha de clases. Bosquejo de una lectura althusseriana del neoliberalismo
Authors: Catanzaro Gisela , Romé Natalia 
Published: February 2021

Partiendo de un breve recorrido por tres perspectivas importantes para el abordaje crítico del llamado “neoliberalismo”, el artículo identifica una vacancia común en su caracterización como momento pos-hegemónico del capitalismo; como racionalidad de gobierno de las subjetividades, o como articulación hegemónica. En todos los casos se trata de análisis que, basándose en la detección de un rasgo de la formación social neoliberal -la lógica del Capital, del Poder, o de las articulaciones políticas- encuentran serias dificultades para pensar su inscripción en la complejidad sobredeterminada de la totalidad histórica. A partir de esa lectura, se propone una revisita de la Teoría de la Reproducción Social formulada por Louis Althusser hacia fines de los años sesenta, poniendo el foco en la pregunta por el complejo de relaciones, tendencias y tensiones que le confieren su consistencia contradictoria y su historicidad heterogénea a una formación social, haciendo lugar a la intelección de procesos estructurales de larga duración, pero a través de los rodeos imprescindibles por los aspectos concretos en que esas tendencias existen y sin los cuales sus determinaciones económicas devienen abstractas: la coyuntura ideológica entendida como el complejo de dispositivos, formaciones discursivas, prácticas y formas interpelativas que dan existencia concreta y a la vez modulan la duración/transformación de un orden dado de relaciones, y los procesos de subjetivación política de sus contradicciones, en su contingencia sobredeterminada. El abordaje propuesto permite caracterizar al neoliberalismo como un proceso coyuntural, inestable pero determinado. Con esta matriz teórica se bosquejan, finalmente, algunas conjeturas generales para comprender de un modo complejo las circunstancias concretas de la coyuntura neoliberal argentina de los últimos años.

Form of Hate Speech Comments on Najwa Shihab Youtube Channels in The General Election Campaign of President and Vice President of The Republic of Indonesia 2019
Authors: Yuliyanti Tsalisa , Subyantoro Subyantoro , Pristiwati Rahayu 
Published: February 2021

Emerging and spreading hate speech online was a growing phenomenon in social media on youtube. Najwa Shihab was a youtube channel that contains shows and comments on political issues in Indonesia, one of them was the 2019 presidential election campaign. The form of hate speech in comments in the Najwa Shihab Channels was forming grammatical construction and construction of the meaning of one hate speech with other utterances. The purpose of this study was to analyze the illocutionary speech acts on hate speech and to analyze hate speech based on the rule of law in Indonesia. The analysis resulted in hate speech on the Najwa Shihab youtube channel audience comments in the General Election campaign in the discourse of the President and Vice President of the Republic of Indonesia in 2019. The approach that used in this study was a theoretical approach, namely a forensic linguistic approach by utilizing pragmatics for data analysis, and a methodological approach, namely a qualitative descriptive approach. The data on hate speech that was analyzed was a fragment of the audience's comments on two programs, namely Mata Najwa and Catatan Najwa. The results showed that there were nine forms of hate speech. Two forms of hate speech were considered to be the style of speech that was widely used by the public in delivering comments on social media. The forms of the speech were "Form of Hate Speech, Assertive Speech - Insult" and "Form of Hate Speech, Assertive Speech - Defamation". The existence of this form of speech can be a reference for the community to process opinions first before conveying it on social media. It's legally can be used as an offense in cases of hate speech.
Influence of phytoncide activity of Thuja occidentalis L. on strains of microorganisms under the action of car load (Dnipro city)
Authors: Sklyar T. V. , Yusypiva T. I. , Slobodyanyuk O. O. 
Published: February 2021

Landscaping of modern cities is impossible without increasing the area of green planting, which performs the function of turning the environment into more health-friendly one. Especially valuable are the species of ornamental plants that have high volatile activity. Because volatiles regulate the balance of pathogenic microflora in the air of cities, they significantly improve people's living conditions. According to the results of a previous study it was found that Thuja occidentalis L. and Th. plicata Donn ex D. Don f. “Zebrina” had the highest bactericidal activity during the winter among members of the family Cupressaceae. Given the frost, wind, gas and smoke resistance of Th. occidentalis, the aim of the study was to investigate the dynamics of phytoncide activity of the needles of this tree species during the year in a relatively clean zone and under the influence of vehicle emissions on plants in the urban ecosystem of Dnipro. The material was collected in all seasons of the year at two monitoring points in Dnipro, which differ in the level of environmental pollution by vehicle emissions. Traffic intensity was determined by the Potichuk & Pilipaka method. Antimicrobial action of Th. occidentalis was studied by the method of placing the crops of microbial test cultures under the effect of volatile secretions of needles and evaluating the result on a scale of phytoncide activity. The test subjects were Staphylococcus epidermidis, Staphylococcus aureus, Micrococcus sp., Bacillus subtilis, Esherechia coli, Pseudomonas fluorescens, Candida albicans. Studies have shown that in a relatively clean area and under the action of traffic loads, the inhibitory effect of needles on the studied strains of microorganisms changes during the year: in winter it is the smallest, in spring begins to grow, in summer is maximum, and in autumn decreases again. Under the man-made growth conditions, the greatest volatile activity of Th. оccidentalis performs on test objects such as: S. aureus, Micrococcus sp. and E. coli. When affected by car load, there is significant inhibition of phytoncide production by needles in the presence of C. albicans, to a lesser extent – Ps. fluorescens and B. subtilis. It is recommended to use Th. оccidentalis in landscaping of urban areas with moderate traffic.
