Branco confere um sentido afetivo – baseado em afetos e produtor destes – no contato com arquivos dinâmicos e dotados de uma importância mnêmica que extrapola a fisicalidade, fazendo deles documentos imateriais e chamados à produção.
O lírico-ciborgue de Angélica Freitas: googlear para simular
Authors: Souza Luciéle Bernardi de , Souza Luciane Bernardi de
Published: November 2021

Este trabalho parte de uma reflexão sobre a imbricação entre o humano e a máquina na constituição do fazer literário. A série 3 poemas com auxílio do google, da poeta Angélica Freitas, suscitou a reflexão que será desenvolvida aqui, pois a autora valeu-se de buscas no Google para, ao “transcrever” os resultados de tais pesquisas, problematizar a criação poética via um eu-lírico transmutado em um lírico-ciborgue. Neste trabalho, através da análise dos poemas e tendo em vista a importância da dimensão autoral envolvida, pensamos o fazer literário enquanto uma simulação de discursos presentes em nossa sociedade, uma potência poética que problematiza a criação literária e o lugar político da poesia contemporânea.
Tools and food on heat lamps: pyrocognitive sparks in New Caledonian crows?
Authors: Jacobs Ivo , von Bayern Auguste M.P. , Osvath Mathias
Published: November 2021

Fire has substantially altered the course of human evolution. Cooking kindled brain expansion through improved energy and time budgets. However, little is known about the origins of fire use and its cognitive underpinnings (pyrocognition). Debates on how hominins innovated cooking focus on archaeological findings, but should also be informed by the response of animals towards heat sources. Here, we report six observations on two captive New Caledonian crows (Corvus moneduloides) contacting heat lamps with tools or placing raw food on them. The tools became singed or melted and the food had browned (and was removed). These results suggest that New Caledonian crows can use tools to investigate hot objects, which extends earlier findings that they use tools to examine potential hazards (pericular tool use), and place food on a heat source as play or exploration. Further research on animals will provide novel insights into the pyrocognitive origins of early humans.
FM Stations’ Role in Rural Development: The Case of Northern Ghana
Authors: Andani Mu-azu Iddirisu , Antwi-Boateng Osman
Published: November 2021

Over the past two decades, Ghana’s media landscape has undergone radical transformation, leading to the emergence of hundreds of frequency modulation (FM) stations across the country. These stations have become the country’s most powerful mediums of communication, carrying an array of programs aimed at diverse audiences. With northern Ghana as a case study, this research examines FM stations’ role in rural development, their mode of impact, and their attendant challenges. This is achieved via qualitative methodology; that is, in-depth interviews with station managers and local development stakeholders, supplemented by programming content analysis of ten FM stations. Findings indicate that FM stations in northern Ghana, irrespective of their classification, aid rural development by serving as an endogenous conduit for the transfer of information that promotes community development and empowerment. This is achieved through programming in local dialects, local musical and cultural programs, expert presentations, interactive phone-in sessions, and news presentations. Challenges include the lack of employee professionalism, financial constraints, poor audience research, technical challenges, excessively partisan political coverage, and lack of original programming.
Movers, Motives, and Impact of Illegal Small-Scale Mining: A Case Study in Ghana
Authors: Antwi-Boateng Osman , Akudugu Mamudu
Published: November 2021

This research unravels the agents and driving motivation behind the rise of illegal small-scale mining in Ghana and its impact. This is accomplished via a qualitative study using illegal small-scale mining in the Talensi and Nabdam districts of Ghana as a case study. At the forefront of this phenomenon are rent-seeking elites, whereas structural factors such as rising unemployment and high population growth, as well as opportunistic factors including low barriers to entry, get-rich quick syndrome, and political corruption/weak institutions are fueling it as well. Although there are some economic benefits of illegal small-scale mining, these benefits are undermined by factors associated with the Resource Curse Hypothesis (RCH) or the ‘Paradox of Plenty.’ We argue that most illegal small-scale mining communities are characterized by increased rent-seeking activities by diverse stakeholders particularly the elites, poor investments in human capital development, and weak institutional structures and processes. To sustainably address the illegal small-scale gold mining menace in Ghana, all efforts should be aimed at holistically dealing with the rent-seekers, especially the elites involved, eliminating their motives and removing the conditions that facilitate their involvement.

The current situation of Coronavirus Disease 2019 (COVID-19) worldwide is still very severe. Presently, many breakthroughs have been accomplished in the research and development of drugs for the treatment of COVID-19, especially vaccines; however, some of the so-called COVID-19-specific drugs highlighted in the early stage failed to achieve the expected curative effect. There is no antiviral therapy available, by stimulating protective immunity vaccine is the best choice for the future management of infection. Therefore, we aimed to identify the latest developments in the research and development of these drugs and vaccines and provide a reference for the prevention and treatment of COVID-19.
The music teacher in ‘on-the-spot’ musical interactions: A practitioner research study
Authors: De Baets Thomas
Published: November 2021

This practitioner research, conducted by a secondary school music teacher, deals with two complementary questions: the conceptual question how one could define the ‘artistry’ of a music teacher in the context of his teaching practice, and the empirical question in how far the music teacher’s actions can determine the quality of the musical interactions with his students. The paper elaborately describes the institutional context for this (doctoral) practitioner research study, and integrates two premises, one regarding the negative image of the school subject music, and another about the vagueness and the ongoing discussions about the required competences of a ‘good’ music teacher. The first question is dealt with in a theoretical way, resulting in a working definition for a music teacher’s ‘artistry’: ‘a music teacher’s “artistry” lies within the extent to which he can apply his musical competences in “immediate” teaching situations’. The second question is studied empirically using a set of qualitative data sources, derived from the practitioner researcher’s teaching practice, that were analysed by means of a self-developed ‘three-dimensional matrix of the music teacher’s real-time teaching actions’. This results in a set of 10 categories in which the music teacher clearly demonstrates ‘unprepared non-routinised musical actions’.
Enabling impedance-based physical human–multi–robot collaboration: Experiments with four torque-controlled manipulators
Authors: Dehio Niels , Smith Joshua , Wigand Dennis L. , Mohammadi Pouya , Mistry Michael , Steil Jochen J.
Published: November 2021

Robotics research into multi-robot systems so far has concentrated on implementing intelligent swarm behavior and contact-less human interaction. Studies of haptic or physical human-robot interaction, by contrast, have primarily focused on the assistance offered by a single robot. Consequently, our understanding of the physical interaction and the implicit communication through contact forces between a human and a team of multiple collaborative robots is limited. We here introduce the term Physical Human Multi-Robot Collaboration (PHMRC) to describe this more complex situation, which we consider highly relevant in future service robotics. The scenario discussed in this article covers multiple manipulators in close proximity and coupled through physical contacts. We represent this set of robots as fingers of an up-scaled agile robot hand. This perspective enables us to employ model-based grasping theory to deal with multi-contact situations. Our torque-control approach integrates dexterous multi-manipulator grasping skills, optimization of contact forces, compensation of object dynamics, and advanced impedance regulation into a coherent compliant control scheme. For this to achieve, we contribute fundamental theoretical improvements. Finally, experiments with up to four collaborative KUKA LWR IV+ manipulators performed both in simulation and real world validate the model-based control approach. As a side effect, we notice that our multi-manipulator control framework applies identically to multi-legged systems, and we execute it also on the quadruped ANYmal subject to non-coplanar contacts and human interaction.
The ontological politics of freshness: Qualities of food and sustainability governance
Authors: Evans David M. , Jackson Peter , Truninger Monica , Baptista João A.
Published: November 2021

Freshness is a key feature of contemporary food systems, however its industrial production as a quality of food carries adverse consequences. Accordingly, this paper approaches freshness as a matter of concern. Drawing on extensive fieldwork across sites of food production and consumption in the UK and Portugal, we identify four enactments of freshness. The analysis zooms in on the specific case of plastic food packaging and uses these enactments to consider a series of questions about realities and the relationships between them. Since packaging is an issue that readily overflows to encompass a broader suite of propositions about food, we argue that freshness is a suitable focus around which to assemble hybrid forums to debate future possibilities. Joining a body of recent work that brings relational-materialist sensibilities to bear on sustainability governance, we demonstrate that these ideas are not exhausted by a concern with the ways in which existing ontologies are brought together in policy. To conclude, we suggest that attention to the multiple ontologies of qualities complements and extends approaches that focus on objects by offering a conduit that brings understandings of markets into discussions of ontological politics.
Long tail metaphysics: The epistemic crisis and intellectual freedom
Authors: Hartman-Caverly Sarah
Published: November 2021

In reaction to the epistemic crisis, efforts to restrict free expression and access to information have not only failed to preserve the truth, but sometimes also suppressed it. Libraries’ commitment to intellectual freedom creates unique opportunities to deliver alternative solutions. By renewing the emphasis on intellectual freedom in core library functions like collections, education, and programming, libraries can provide the epistemic resources that patrons need amidst a broader context of distrust, manipulation, and censorship. This essay examines the epistemic crisis in the USA in light of intellectual freedom and the IFLA Statement on Libraries and Intellectual Freedom. Organized into three parts, this piece explores plurality as normative in the human condition, considers the impact of information and communications technology on free expression and the legitimacy of information institutions, and reconciles the emerging tensions by applying concepts from virtue epistemology to intellectual freedom. The essay concludes with considerations for library practice.
Experimental investigation of the air flow in a simplified underhood environment
Authors: Franzke Randi , Sebben Simone , Willeson Emil
Published: November 2021

In this paper, a simplified underhood environment is proposed to investigate the air flow distribution in a vehicle-like set-up and provide high quality measurement data that can be used for the validation of Computational Fluid Dynamic methods. The rig can be equipped with two types of front openings representative for electrified vehicles. Furthermore, it is possible to install differently shaped blockages downstream of the fan to imitate large underhood components. The distance between the blockages and the fan can be varied in longitudinal and lateral direction. The measurements are performed with Laser Doppler Anemometry at a fixed distance downstream of the fan. The results show that the lack of an upper grille opening in the configuration for a battery electric vehicle has a notable impact on the flow field in the reference case without any downstream blockage. However, the differences in the flow field between the two front designs become less when a downstream obstruction is present. The longitudinal and lateral position of the blockages have a minor impact on the flow field compared to the shape of the obstacle itself.
Galerkin finite element analysis for peristaltic flow of micropolar fluid through porous soaked inclined tube independent of wavelength
Authors: Ahmed B. , Khan S. U. , Ahmad S. , Shehzad S. A. , Chammam Wathek
Published: November 2021

In this novel numerical investigation, the application of well-renowned numerical technique known as Galerkin finite element method on full form of Navier-Stokes equations presented peristaltic flow of non-Newtonian fluid confined by a uniformly saturated porous medium. The rheological aspects of non-Newtonian material are discussed by considering micropolar fluid. The flow model consists of system of nonlinear partial differential equations with mixed boundary condition. The flow also experienced an externally applied magnetic field. The effects of inertial forces and the results independent of wavelength are obtained by dropping the presumptions of lubrication theory in modelling the governing equations. The numerical solution for formulated problem in terms of partial differential expressions is worked out via Galerkin finite technique in view of six nodal triangular elements. The enhancement in the inertial forces gives impressive pressure enhancement against wavelength while opposed the fluid flow in the vicinity of peristaltic walls of the tube but supported the fluid flow in the central region of the tube. The present results are also compared with the available results after applying lubrication theory and found in reliable agreement.
Sensorless control scheme based on sliding modes for interior permanent magnet synchronous motor
Authors: Alvaro-Mendoza Enrique , Salas-Peña Oscar S , De León-Morales Jesús
Published: November 2021

In this article, a sensorless speed control design for the interior permanent magnet synchronous motor based on sliding mode approach is proposed. The control objective is to drive the rotor speed to desired reference despite load torque disturbances and parameter uncertainties. The proposed control strategy combines a Sliding Mode Controller with an Adaptive Interconnected Observer design based on sliding mode techniques, which allows to estimate the rotor speed, the stator resistance and the load torque. Furthermore, experimental results, including a comparative study against schemes from literature, illustrate the robustness and performance of proposed approach.
“The Rest of my Childhood was Lost”: Canadian Children and Adolescents’ Experiences Navigating Inflammatory Bowel Disease
Authors: Barned Claudia , Fabricius Alexis , Stintzi Alain , Mack David R , O’Doherty Kieran C
Published: November 2021

Children and adolescents with Inflammatory Bowel Disease (IBD) face significant and unique challenges related to their condition. The aim of this study was to better understand some of these challenges, and to explore how Canadian youth respond to them. We interviewed 25 pediatric patients with IBD, ranging in age from 10–17, to find out about their illness experiences. Using a thematic analysis, we discerned three themes: challenges related to diagnosis, making sense of change, and navigating sociability. Taken together, they paint a picture of young people facing great uncertainty prior to diagnosis, pronounced changes to selfhood as they make lifestyle adjustments, and facing difficulties with the implications of reduced sociability because of their disease. We conclude by providing recommendations for the development of resources aimed at helping newly diagnosed pediatric patients navigate these issues.

Published: November 2021

This study aimed to explore the prognostic value of SATB1, SMAD3, and TLR2 expression in non–small-cell lung carcinoma patients with clinical stages I-II. To investigate, we evaluated immunohistochemical staining to each of these markers using tissue sections from 69 patients from our cohort and gene expression data for The Cancer Genome Atlas (TCGA) cohort. We found that, in our cohort, high expression levels of nuclear SATB1n and SMAD3 were independent prognostic markers for better overall survival (OS) in NSCLC patients. Interestingly, expression of cytoplasmic SATB1c exhibited a significant but inverse association with survival rate, and it was an independent predictor of unfavorable prognosis. Likewise, TLR2 was a negative outcome biomarker for NSCLC even when adjusting for covariates. Importantly, stratification of NSCLCs with respect to combined expression of the three biomarkers allowed us to identify subgroups of patients with the greatest difference in duration of survival. Specifically, expression profile of SATB1n-high/SMAD3high/TLR2low was associated with the best OS, and it was superior to each single protein alone in predicting patient prognosis. Furthermore, based on the TCGA dataset, we found that overexpression of SATB1 mRNA was significantly associated with better OS, whereas high mRNA levels of SMAD3 and TLR2 with poor OS. In conclusion, the present study identified a set of proteins that may play a significant role in predicting prognosis of NSCLC patients with clinical stages I-II.

Specifically, I explore (a) the ways in which I experienced othering in educational institutions as a transnational Black girl/woman and how those experiences informed my career path, (b) how I have navigated tensions related to my minoritized identities as a university professor, and (c) ways that I attempt to resist my displacement through my presence and pedagogy.
Vibro-acoustical responses of a sandwich panel consist of aluminum honeycomb core and fabric-reinforced graphite facings
Authors: Wang Luyao , Dai Liming
Published: November 2021

This research presents a numerical study on vibro-acoustic and sound transmission loss behavior of an aluminum honeycomb core sandwich panel with fabric-reinforced graphite (FRG) composite face sheets. The sandwich theory, which assumes the honeycomb core as an orthotropic structural layer, is applied to investigate the free and forced vibration behavior of the panel. The radiated sound power from the panel is quantified by Rayleigh integral method, and the random diffuse field as an incident sound source is derived based on finite element method with the employment of ACTRAN. A validation between the simulated results and the experimental data published is carried out to demonstrate the accuracy and reliability of the present approach. The comparison between different materials of honeycomb sandwich structures illustrates the advantages of the fabric-reinforced graphite honeycomb sandwich structure over the other types of sandwich structures considered. The effects of different boundary conditions and honeycomb structural geometry properties on the acoustical performance of the stiffness of the FRG panel are also investigated. The approach of the present research provides useful guidance for evaluating and selecting the other honeycomb sandwich panels when the vibratory and acoustic behaviors of the panels are considered.

Introduction

Persons living with HIV (PLWH) use tobacco at higher rates than the general population in both high-income countries and low- and middle-income countries. Tobacco use rates are increasing in sub-Saharan Africa, the home to most of the world’s PLWH. As the reach of antiretroviral therapy (ART) expands and HIV-related morbidity and mortality wanes, tobacco use is emerging as a leading cause of disease and death in PLWH. A better understanding of tobacco use behaviors in various settings will be crucial to designing optimal tobacco control strategies.

Methods

In late 2019, we enrolled 50 PLWH cigarette smokers from 6 clinical sites in Nairobi, Kenya (4 HIV care clinics and 2 methadone maintenance programs) for one-on-one interviews focusing on their behaviors and beliefs related to tobacco use.

Results

Fifty PLWH smokers completed the interviews. The mean age was 38.5 ± 9.7 years (range 20-57 years) and 68% were male. All were currently receiving ART. They smoked a mean of 14.9 ± 12.4 cigarettes per day, and 82% reported smoking every day. Only 6% reported dual use of smokeless tobacco products. Nicotine dependence was moderate or high in 74%. More than a third (36%) reported a prior history of tuberculosis. In our sample, use of other substances was common, especially alcohol, marijuana, and methadone. On the motivation to quit scale, 90% were at least in the contemplation stage, but only 2% had ever received behavioral cessation counseling, and only 8% had ever used pharmacotherapy (exclusively nicotine replacement therapy). Participants reported significant concern about developing smoking-related illness, exposing others to secondary smoke, and the financial burden associated with their tobacco use. Measures of intrinsic and extrinsic motivation to quit, smoker and abstainer self-concept, and social support yielded encouraging results regarding the possibility of successful quitting.

Conclusions

Tobacco use is an important health concern in PLWH in Kenya. A more thorough understanding of their tobacco use behaviors and beliefs will provide critical information for providers, public health officials, and policy makers as they redouble their efforts to confront this urgent health challenge.
Newly synthesized Ionic Liquids as potent lubricants and additives to existing lubricant oils
Authors: Myrdek Thomas , Stapels Michael , Kunz Werner
Published: November 2021

Ionic Liquids are promising candidates for next generation green lubricants. We have synthesized 39 Tetraalkylammonium Alkyl Ether Carboxylate Ionic Liquids and tested them for their lubricant capabilities. We measured friction coefficient to assess the transition from the boundary to the hydrodynamic lubrication, the hydrodynamic area and the minimum friction value. Some Ionic Liquids are capable of forming a hydrodynamic layer fully separating two specimens. Compounds with short C-chain of the cationic part show poor tribological behaviour. Similarly, increasing the PO-degree of the anionic part lowers the lubrication power. An increase of the C-chain length improves the tribological behaviour, i.e. the minimum friction value becomes lower. This is due to the formation of a uniform tribolayer of the long-chain carboxylic acids. Higher viscosity of the Ionic Liquids results in low friction coefficients and the development of a hydrodynamic layer. This is due to a strong hydrodynamic pressure, which is formed by the more viscous compound. Addition of small amounts of Ionic Liquids to low performance oils increases their capability to from tribolayers and thus improves their lubricant capability.
The effect of classroom acoustic conditions on literacy outcomes for children in primary school: A review
Authors: Mealings Kiri
Published: November 2021

Literacy skills are essential for success in today’s society. However, classrooms often have suboptimal acoustic conditions for learning. The goal of this review was to synthesize research assessing the effect of different classroom acoustic conditions on children’s literacy. A comprehensive search of four online databases was conducted in August 2021. The search term was classroom AND (noise OR reverberation OR acoustics) AND (reading OR spelling OR writing OR literacy). Eighteen papers were deemed relevant for the review plus an additional seven from their references. The types of acoustic conditions that have been assessed, the types of measures used to assess literacy, and the effect of the acoustic conditions on children’s reading, writing, and spelling outcomes are discussed. Suggestions for the classroom acoustic conditions needed to ensure appropriate literacy development and areas for future research are also considered.
A new framework for imagining the climate commons? The case of a Green New Deal in the US
Authors: Caggiano Holly , Landau Laura F.
Published: November 2021

The Green New Deal is arguably the most ambitious climate policy platform to gain legislative traction in the U.S. to date. A pioneering policy framework in its holistic consideration of climate change, social justice, and economic reform, the resolution would have vast implications for commons governance regimes if enacted. Planning theorists have long debated how to manage the global commons, and this paper adds to that conversation by assessing the Green New Deal’s theoretical underpinnings. Our analysis suggests that in practice, “top-down” Hardinian and “bottom-up” post-Hardinian commons theory coexist, as market and state-based interventions act as layers in the nested enterprises necessary for the formation of a polycentric approach to climate governance. This finding presents a novel theoretical perspective for studying the commons, specifically as we consider the influence of theory on developing policy imagination.
‘I have this subversive curriculum underneath’: Narratives of micro resistance in early childhood education
Authors: Archer Nathan
Published: November 2021

Neoliberal thinking has increasingly shaped global and national policy incursions in early childhood education. Research has highlighted the power effects of such policies with consequences for pedagogy, provision and the professional identities of educators. Less well understood are educator responses to these policies. Whilst literature offers some exploration of resistance movements, little is known from empirical studies about how acts of resistance are enacted individually (and collectively) in the professional lives of early years educators. This article explores how English early childhood educators resist policy constructions of ideal professional identities. Using reconceptualized critical theory, this paper considers both neoliberal shaped demands on early educators and their resistance to these. Employing data from professional life story interviews ( n = 16) by early educators in a range of contexts, narratives were constructed which document their responses to ECE policies. This paper draws on three of these narratives. A Critical Narrative Analysis reveals that educator resistances are not always large scale, collective or mobilized but are often expressed in atomized contexts through a dispersed network of actors. Individual responses included ‘micro resistances’ which were often local, quiet and invisible but multiple. The paper offers novel insights into c/overt resistances revealing educators’ complex, nuanced and subversive responses to discursive policy manoeuvres.
Preschoolers’ social emotional learning in children’s museums and community playgrounds
Authors: Luke Jessica J , Brenkert Sarah , Rivera Nicole
Published: November 2021

Interest in social emotional learning (SEL) is higher than ever, as parents, educators, and policymakers recognize that children need more than cognitive skills for later life success. However, most SEL research has been conducted in formal education settings. This article describes results from an empirical study of 4–5 years old SEL in two informal learning settings, including children’s museums and community playgrounds. Members of the Children’s Museum Research Network observed 606 preschool children using the Revised/Shortened Minnesota Preschool Affect Checklist (MPAC-R/S). Findings show that preschool children engaged in SEL in both settings, but that significantly more instances of SEL were seen in children’s museums compared with community playgrounds. We argue that children’s museums may provide an important, peer-to-peer opportunity for children to develop and practice their SEL, one that is unique from the more common teacher-child interactions provided in schools.
Vapour resistance of wind barrier tape: Laboratory measurements and hygrothermal performance implications
Authors: Johnsen Ida-Helene , Andenæs Erlend , Gullbrekken Lars , Kvande Tore
Published: November 2021

In the building industry, the interest into adhesive tape to achieve a more tight and robust building envelope has increased rapidly in recent years. With an increasing demand for energy efficiency in buildings, national building authorities are strengthening building requirements to mitigate and adapt to future climate impacts. This paper studies the water vapour permeability of adhesive tape for building purposes. A water vapour permeable wind barrier is essential to enable drying of the external side of the building envelope. Laboratory measurements have been conducted to evaluate how the drying conditions of the wind barrier layer are affected by the use of wind barrier tape. The results show that all the wind barrier tapes tested can be defined as significantly more vapour tight than the wind barrier itself. The wind barrier used as reference was found to have an sd-value of 0.03 m while tape ranged between 1.1 and 9.24 m. To ensure adequate drying and minimize the risk of moisture damages, the wind barrier layer should be vapour open. In an investigated construction project, the amount of tape constitutes 13% of the area of the building’s wind barrier. Further simulations need to be conducted to accurately determine the drying conditions and the following consequences.
Reconstructing policy transfer in adult and vocational education and training
Authors: Barabasch Antje , Bohlinger Sandra , Wolf Stefan
Published: November 2021

The article contributes to the understanding of educational policy transfer with a particular focus on VET and labour-market related training. A review of VET policy transfer literature is followed by a description of travelling VET reforms in adult and vocational education and training around the globe. Historical foundations of VET policy transfer are described with an emphasis on lending and borrowing from the global North to the global South. Finally, contemporary forces that influence global policy transfer, derived from personal observation, are described. We aim to contribute to a better understanding of policy cycles by depicting the influence of different dynamics on decision-making for policy transfer in VET. We argue that there can be various reasons to policy transfer, not just attractiveness of a particular educational system or approach, but also global industry demands for workforce development or the influence of big data and social media.
Maternal and fetal characteristics to predict c-section delivery: A scoring system for pregnant women
Authors: Irwinda Rima , Hiksas Rabbania , Lokeswara Angga Wiratama , Wibowo Noroyono
Published: November 2021

Introduction:

Cesarean section is one of the most common obstetrical interventions that has been performed at an increasing rate globally, due to both medical and non-medical reasons. This study aims to develop a prediction tool for pregnant women potentially needing c-section, such that necessary preparations from the mothers, families, and health providers can be made.

Methods:

A total of 603 pregnant women were recruited in the first phase of c-section prediction tool development. The association between the maternal and fetal factors on the risk of c-section were analyzed, followed by a stepwise multivariate regression analysis. In the next phase, 61 pregnant women were enrolled for external validation. Discrimination was assessed using area under the curve. The calibration plot was then made and assessed using the Hosmer–Lemeshow test.

Results:

There were 251 (41.6%) cases of vaginal delivery and 352 (58.4%) of c-section assessed. Multivariate analysis showed that gestational age < 37 wg (OR: 1.66, 95% CI: 1.10–2.51), pre-pregnancy body mass index (underweight) (OR: 0.40, 95% CI: 0.22–0.76), no history of vaginal delivery (OR: 2.66, 95% CI: 1.76–4.02), history of uterine surgery (OR: 8.34, 95% CI: 4.54–15.30), obstetrical complications (OR: 5.61, 95% CI: 3.53–8.90), birthweight ⩾ 3500 g (OR: 4.28, 95% CI: 2.16–8.47), and non-cephalic presentation (OR: 2.74, 95% CI: 1.53–4.89) were independently associated with c-section delivery. Those parameters were included in a 7-item scoring tool, with consecutive predictive scores of 1,–1,2,3,3,2,2,1. The area under the curve result was 0.813 (95% CI: 0.779–0.847), indicating a good predictive ability. The external validation showed AUC: 0.806, 95% CI: 0.694–0.917, Hosmer–Lemeshow test p = 0.666 and calibration plot coefficient of r = 0.939.

Conclusion:

A total of 7 maternal-fetal factors were found to be strongly associated with c-section delivery, including gestational age < 37, maternal underweight body mass index, previous uterine surgery, obstetrical complications, birthweight ⩾ 3500, history of vaginal delivery, and non-cephalic presentation. Using these factors, a prediction tool was developed and validated with good quality.
The relative age and birth order effect in Japanese professional football
Authors: Yamamoto Dai , Takafuji Jun , Kato Tomoyuki , Kawai Kazutake , Shimizu Chihiro
Published: November 2021

This study examines how the probability of becoming a professional football player depends on the birth month (relative age effect) and birth order. These two factors are random and cannot be controlled by the athlete. If these factors influence the probability of the occurrence of top athletes, they not only create inequality but also close the disciplines to potentially talented athletes, lowering the level of competition. Therefore, in this study, we statistically clarified the presence or absence of “giftedness of life” by focusing on the birth month and birth order of professional football league players in the Japan Professional Football League (J-League). Our results indicate that the probability of the occurrence of J-League players decreases significantly with increasing birth order and birth month (180 days, from April onward). Moreover, we found that second-born players with an older brother had higher estimated salaries than players without siblings. These results reveal the characteristics of excellent football players and suggest the importance and direction of improvement in talent discovery and development in sports. Based on our results, we recommend improvements in the player training system to buffer the effects of relative age effect and birth order.

Published: November 2021

There is a close link between moral education and sports activities. A well-organized sport can be an excellent means of transferring positive values to children and adolescents, which can influence motivation and group processes. This study aimed to analyse (a) the relationships between social, personal and individualistic values, motivational orientation and team cohesion amongst young soccer players and (b) compare differences in these variables between players competing in different age categories. Our participant sample comprised 401 male soccer players of Spanish teams (mean age = 14.64 years) competing in official competitive leagues, of five age categories, Under-10 years to Under-19. All participants responded to three instruments: the Values Scale for Positive Adolescent Development, the Perception of Success Questionnaire and the Group Environment Questionnaire. Correlation and regression, and analysis of differences between categories were performed. The results confirm that personal values are mainly related to task orientation, and individualistic values to ego orientation. The values of responsibility, integrity and honesty were the best predictors of task orientation, and social recognition and hedonism predict ego orientation. Honesty and responsibility were the main predictors of both task and social cohesion. Younger players showed a higher level of social values, task orientation and social cohesion, while older players show higher individualistic values and ego orientation. Implications for research or practice are discussed.

Violent crime is a concern in the United States. Past research has suggested different correlates, including poverty, mental health disorders and the presence of guns. One particular theory, named the facilitation hypothesis, states that firearms enhance the power of an aggressor, they reduce the necessity of a physical attack, and encourage those who may not otherwise resort to violence. We look at various social factors and their relationship regarding different indicators of violent crime. We find that at the state level, gun ownership is correlated with violent crimes and income inequality with homicides specifically and we find support for the facilitation hypothesis. Future public policies which target these issues appear likely to bear fruit toward the goal of reducing crime.

For micro air vehicles (MAV), the precise prediction of aerodynamic force plays an important role. The aerodynamic force of a comparative low Reynold number (Re) vehicle tends to be affected by the different flow modes. In this paper, the aerodynamic performance of a three-dimensional NACA0012 airfoil is studied numerically. A range of angles of attack ( α) 0°−25° and Reynolds number 1000 is considered. Mean and fluctuating coefficients of aerodynamic forces around NACA0012 airfoil are analyzed for different wake modes. The difference of aerodynamic forces between two and three-dimensional simulations are compared. The results show that the wake remains steady two-dimensional for lower angles of attack. At α = 9°, Von Karman vortex pattern is noticed. Flow transition to three-dimensional as the angle of attack increases from α = 13°. 3D wake is found to be stable with parallel shedding mode for 14°-17°. However, these modes become finer with the gradual increase in angle of incidence. While, wake loses its three-dimensional stability to chaotic with gradual increment in angle of attack afterwards.
Collective redress and workers’ rights in Slovenia
Authors: Kresal Barbara
Published: November 2021

In 2017, the Collective Actions Act introduced a new type of lawsuit – the collective action – into the Slovenian legal order. A collective action can be lodged in cases of instances of so-called ‘mass harm’, including mass violations of workers’ rights. This could improve the effectiveness of enforcement of workers’ rights in practice. Instead of a number of individual labour disputes concerning the same or similar violations of workers’ rights, a collective action can be lodged by trade unions or other representative collective actors in this field. Both opt-in and opt-out approaches are possible and the decision on this is left to the discretion of the court. Despite many positive aspects, only one collective action in the area of labour rights has been lodged to date. In this contribution I analyse legal regulation of the existing collective redress mechanism and possible reasons for deficiencies discerned in its functioning in practice.
Bimanual Grasping Adheres to Weber's Law

Weber's law states that our ability to detect changes in stimulus attributes decreases linearly with their magnitude. This principle holds true for many attributes across sensory modalities but appears to be violated in grasping. One explanation for the failure to observe Weber's law in grasping is that its effect is masked by biomechanical constraints of the hand. We tested this hypothesis using a bimanual task that eliminates biomechanical constraints. Participants either grasped differently sized boxes that were comfortably within their arm span (action task) or estimated their width (perceptual task). Within each task, there were two conditions: One where the hands’ start positions remained fixed for all object sizes (meaning the distance between the initial and final hand-positions varied with object size), and one in which the hands’ start positions adapted with object size (such that the distance between the initial and final hand-position remained constant). We observed adherence to Weber's law in bimanual estimation and grasping across both conditions. Our results conflict with a previous study that reported the absence of Weber's law in bimanual grasping. We discuss potential explanations for these divergent findings and encourage further research on whether Weber's law persists when biomechanical constraints are reduced.

Published: November 2021

This study examines the influence of financial literacy, gender, annual family income and neuroticism personality trait on the probability of millennial equity investors to suffer from selected cognitive biases (availability bias, representative bias, mental accounting bias and anchoring and adjustment bias). Binary logistic regression method is applied to conduct the analysis. Results of the current study indicate that selected demographic factors and investor personality are significant in predicting the probability of millennial Indian investor to suffer from the biases under consideration. For availability bias, financial literacy; for representative bias, financial literacy, neuroticism and gender; for mental accounting bias, neuroticism, gender and annual family income; and for anchoring and adjustment bias, financial literacy, neuroticism, gender and annual family income are found as significant predictors.
Factors Affecting Patient Perceptions and Satisfaction with Telemedicine in Outpatient Clinics

Published: November 2021

Despite the increasing use of telemedicine, patients’ views on telemedicine remain unclear. This study aimed to understand factors affecting patient perceptions and satisfaction with telemedicine services. 235 patients were surveyed on accessibility to telemedicine clinics, medical specialities and satisfaction with the services. 58.3% confirmed having a stable internet connection, 24.3% used telemedicine services in internal medicine clinics, and only 5.1% accessed the telemedicine services in psychiatry clinics. 68.5% used the telephone to access telemedicine service, while only 6.4% used the hotline. Over half of patients confirmed their ability to hear clearly and speak easily with their healthcare providers during their consultations. 55.7% confirmed they were satisfied with their telemedicine experience, while 23.4% were neutral and 8.9% were unsatisfied. There was a significant difference in the rates of satisfaction between female and male respondents (p-value<0.001). Those with stable internet connection had significantly higher satisfaction rates with telemedicine services (p-value<0.001). The rates of satisfaction with telemedicine services were significantly higher in Cardiology and Orthopaedic clinics. Larger multi-center studies examining other factors affecting patients’ satisfaction are recommended.

Since the outbreak of the COVID-19 pandemic, there has been a rapid expansion in vaccine research focusing on exploiting the novel discoveries on the pathophysiology, genomics, and molecular biology of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Although the current preventive measures are primarily socially distancing by maintaining a 1 m distance, it is supplemented using facial masks and other personal hygiene measures. However, the induction of vaccines as primary prevention is crucial to eradicating the disease to attempt restoration to normalcy. This literature review aims to describe the physiology of the vaccines and how the spike protein is used as a target to elicit an antibody-dependent immune response in humans. Furthermore, the overview, dosing strategies, efficacy, and side effects will be discussed for the notable vaccines: BioNTech/Pfizer, Moderna, AstraZeneca, Janssen, Gamaleya, and SinoVac. In addition, the development of other prominent COVID-19 vaccines will be highlighted alongside the sustainability of the vaccine-mediated immune response and current contraindications. As the research is rapidly expanding, we have looked at the association between pregnancy and COVID-19 vaccinations, in addition to the current reviews on the mixing of vaccines. Finally, the prominent emerging variants of concern are described, and the efficacy of the notable vaccines toward these variants has been summarized.
