The Effect of Multiplayer Video Games on Incidental and Intentional L2 Vocabulary Learning: The Case of Among Us

Vocabulary learning has been traditionally considered central to second language learning. It may take place either intentionally, by means of deliberate attempts to commit factual information to memory, or incidentally, as a consequence of other cognitive processes involving comprehension. Video games, which have been extensively employed in educational contexts to understand lexical development in foreign languages, foster both exposure to and the production of authentic and meaning-focused vocabulary. An empirical study was conducted to explore the effect of playing an online multiplayer social deduction game (i.e., a game in which players attempt to uncover each other’s hidden role) on incidental and intentional second language (L2) vocabulary learning. Secondary school pre-intermediate English as a Foreign Language (EFL) students (n = 54) took a vocabulary pre-test that identified eight unknown words likely to appear in the video game Among Us. Then, students were randomly assigned to different groups of players and to different learning conditions—within each group, half of the players were given a list of phrases containing such target words, which they were encouraged to meaningfully use in the game by means of written interaction. In doing so, students learnt some target words intentionally and provided contextualized incidental exposure to other players. They took a vocabulary test after two sessions of practice with the game to explore intentional and incidental L2 vocabulary learning gains. The pre- and post-tests suggested, among other results, that players using new L2 words in the game Among Us would retain more vocabulary than players only encountering them, that vocabulary intentionally input helped other users trigger incidental vocabulary learning, and that repetition had a positive effect on L2 vocabulary learning.
Sources of Resilience in Frontline Health Professionals during COVID-19

Background: While the challenges for psychological well-being for Australian healthcare workers have been documented, there has been a dearth of qualitative research on the sources of resilience that sustained workers during the COVID-19 pandemic. This study identified sources of resilience that clinicians used to cope with frontline challenges during the COVID-19 pandemic. Methods: Semi-structured interviews were conducted with 20 frontline health professionals, across five Australian hospitals, between October 2020 and April 2021. The interviews were recorded and transcribed, and the results were analysed using thematic analysis based on a phenomenological approach. Results: Three sources of resilience were identified by respondents: personal, relational, and organisational. A positive mindset, sense of purpose, and self-care behaviours emerged as key sources of personal resilience. Teamwork, altruism, and social support from family and friends contributed to relational resilience. Leadership, effective communication, and effective implementation of COVID-19 policies were associated with resilience at the organisational level. Frontline healthcare workers also voiced the need for the implementation of further strategies to support personal resilience whilst nurturing resilience within clinical teams and across entire healthcare organisations. Conclusions: Trust in healthcare systems, organisation leaders, colleagues, and personal support teams was an overarching theme supporting resilience.
Resilience in Sports: A Qualitative Discussion on Risk Factors and Protective Factors among Performance Development (Pd) Athletes

Athletes who reach a developed performance level, faced various challenges and difficulties, but they are still able to remain resilient. This study was conducted to explore the aspects of resilience among athletes within Performance Development (PD) category. Focused group discussions using semi-structured interview based on Multilevel Classification System for Sport Psychology (MCS-SP) model were conducted on 20 Perak state athletes who were undergoing Malaysia Sports Game 2021 (SUKMA) preparation program. The results of the study found five themes related to risk factors faced by athletes in maintaining developing performance such as performance, change, behavior, psychology and interpersonal issues. The study suggested that acceptance and commitment as part of psychological protective factors that help athletes maintain resilience. The study also produced a model of resilience among PD athletes which can be used as a reference in sports training programs.
Environmental Management System towards Environmental Performance of Hotel Industry: Does Corporate Social Responsibility Authenticity Really Matter?

Environmental Management Initiatives (EMI), as part of the sustainability management movement, have become an integrated part of the organisational management practices and of the current research. Since the implementation of Environmental Management System (EMS), there have been many studies analysing this relationship with the environmental performance. Corporate Social Responsibility (CSR) also gained a great importance for the organisations’ performance, including their performance in the environmental area. However, previous studies analysed the direct link between those variables and environmental performance, while the mediating effect of those variables has not been tested yet because using a mediator in the relationship between two variables is a rather new approach in the research area used in the behavioural sciences area. This research analyses the role of EMI in defining the Environmental Performance (EP) of hotel industry, given the strong relationship between those two variables and the importance of the tourism sector for the economic development, both in the developed, but especially in the developing countries. It also investigates the CSR authenticity as mediator between EMI and EP link. Data was collected through a questionnaire of managers of the hotels in Pakistan. Correlation, Structural Equation Model and linear regressions were applied for testing the hypotheses and for checking the viability of the model. Findings revealed that EMI and CSR authenticity are important and significant determinants of EP in the hotel industry. Findings show that CSR authenticity acts as a mediator for the EMI and EP link. The stakeholder pressures and customers’ environmental awareness have forced the hotel industry to implement environmental standards and this shift of focus is more important in the hotel industry. The current research demonstrates that efforts of EMI is a prerequisite for enhancing CSR authenticity in the environmental area, and this, in its turn, contributes to the increase of the EP of hotel and tourism sector in a developing country. Given the lack of large financial resources of the developing countries, this model is an important outcome for the tourism industry that helps hotels to become green, to attract more clients and to gain competitive advantages.
CD44 Variant Exon 6 Isoform Expression as a Potential Predictor of Lymph Node Metastasis in Invasive Breast Carcinoma of No Special Type

Background Invasive breast carcinoma of no special type (IBC-NST) is the most widespread invasive carcinoma subtype causing primarily regional metastases of the lymphatic node (LNM). The capacity of CD44 variant exon 6 (CD44v6) expression as an LNM predictor biomarker in IBC-NST was explored. Methods We conducted a cross-sectional research with 48 paraffin blocks containing IBC-NST primary tumors that were divided into two groups by LNM. The assessment has been carried out in terms of age, tumor size, tumor grade, lymphovascular invasion (LVI), and CD44v6 expression. The expression of CD44v6 was analyzed on the grounds of immunohistochemical (IHC) staining, while other data were taken from archives. Statistical analysis is carried out by univariate, multivariate, and AUROC. Results CD44v6 exhibits a dominant expression in IBC-NST tumor cells. Univariate analysis revealed a significant association between CD44v6 and LNM status (p = 0.001). Multiple logistic regression results showed that CD44v6 expression and LVI were significantly associated with LNM with OR 10.7 (95% CI: 2.43 to 47.08) and 6.22 (95% CI: 1.4 to 27.88), respectively. CD44v6 expression was able to discriminate against LNM with AUROC 0.863 ± 0.053 (95% CI: 0.759 to 0.967) at the H-score cut-off 133.889 (75% sensitivity and 83.3% specificity). Conclusion CD44v6 expression and LVI are potential predictors of LNM in IBC-NST. The H-score cut-off of the CD44v6 expression can also be used as a threshold for classification in further investigation.
Robocup small size league : active ball handling system

The RoboCup offers a research platform to advance robotics and multi-robot cooperation in dynamic environments. This project builds on work previously done to develop a research platform for multi-robot cooperation at Stellenbosch University. This thesis describes the development of an active ball handling system for a robot in the RoboCup Small Size League (SSL). This was achieved by building on the work done in the previous projects. The hardware for the kicker and dribbler mechanisms on the robot were implemented and tested to characterise their capabilities. The kicker was characterised to control the speed at which a ball is kicked and the dribbler for optimal control over a ball. More accurate movement was required and the Proportional Integral and Derivative (PID) controllers for translational and rotational movement on the robot were improved. The test results show an improvement in straight line trajectory tracking when compared to those of the previous controllers. Dribble control sensors were implemented on the robot for successful dribbling by the robot. This resulted in a significant improvement to the dribbling ability of the robot when these sensors are used. This dribbling ability was compared to the dribbling ability of the robot when no feedback was received from the sensors. Lastly a proposed curved trajectory tracking algorithm was tested by combining translational and rotational movement of the robot. This algorithm showed the capabilities of the robot to follow a curved trajectory with the improved translational and rotational controllers. iii Stellenbosch University http://scholar.sun.ac.za
Serotype Replacement after Introduction of 10-Valent and 13-Valent Pneumococcal Conjugate Vaccines in 10 Countries, Europe

We evaluated invasive pneumococcal disease (IPD) during 8 years of infant pneumococcal conjugate vaccine (PCV) programs using 10-valent (PCV10) and 13-valent (PCV13) vaccines in 10 countries in Europe. IPD incidence declined during 2011–2014 but increased during 2015–2018 in all age groups. From the 7-valent PCV period to 2018, IPD incidence declined by 42% in children <5 years of age, 32% in persons 5–64 years of age, and 7% in persons >65 years of age; non-PCV13 serotype incidence increased by 111%, 63%, and 84%, respectively, for these groups. Trends were similar in countries using PCV13 or PCV10, despite different serotype distribution. In 2018, serotypes in the 15-valent and 20-valent PCVs represented one third of cases in children <5 years of age and two thirds of cases in persons >65 years of age. Non-PCV13 serotype increases reduced the overall effect of childhood PCV10/PCV13 programs on IPD. New vaccines providing broader serotype protection are needed.

Effects of bearing estimation improvements of non-conventional beamformers on bearings-only tracking

It has been argued in the open literature that significant improvement in towed array spatial resolution is possible through a variety of non-conventional beamforming techniques such as adaptive and synthetic aperture methods. These techniques are particularly attractive for short arrays where the only other alternative is to lengthen the array at great cost. However, it is important to understand the effect of these techniques on the performance of the complete sonar system. The purpose of this paper is to evaluate and assess the relative merits provided by applying a variety of adaptive and synthetic aperture beamforming techniques to towed array sonar data in order to localize and track signals of interest while suppressing strong interferers. The impact and merits of these techniques will be contrasted with the localization and tracking performance obtained using the conventional beamformer.
Relación entre la enseñanza bilingüe en educación física con el rendimiento académico y nivel de práctica de actividad física

Este estudio pretende analizar la relación existente la motivación en las clases de educación física en entorno bilingüe con el rendimiento académico y el nivel de práctica de actividad física. Se realizó un estudio para conocer el nivel de satisfacción de los alumnos hacia las clases de educación física bilingües en inglés. Participaron a 256 alumnos de la etapa de la ESO, (12-17 años). Como instrumento se utilizó el cuestionario Versión Española del Sport Satisfaction Instrument (SSI) y el adaptado al Aprendizaje de la Educación Física Bilingüe en Inglés (SSI-PE). En base a los resultados obtenidos, podemos concluir que los alumnos con mejores notas, corresponden con los que normalmente participan y se lo pasan mejor en las clases de EF, tanto en español como en inglés. Los alumnos que no realizaban deporte, se sentían menos motivados y satisfechos con las clases de educación física. El nivel de satisfacción en las clases de EF es menor cuando las clases se imparten en inglés. Por lo que es necesario involucrar a la comunidad educativa y las familias en estrategias encaminadas al incremento de la práctica de actividad física, apoyado el bilingüismo como estrategia educativa beneficiosa para la formación académica de los escolares
Management of obstructive colon cancer: Current status, obstacles, and future directions

Approximately 10%–18% of patients with colon cancer present with obstruction at the initial diagnosis. Despite active screening efforts, the incidence of obstructive colon cancer remains stable. Traditionally, emergency surgery has been indicated to treat patients with obstructive colon cancer. However, compared to patients undergoing elective surgery, the morbidity and mortality rates of patients requiring emergency surgery for obstructive colon cancer are high. With the advancement of colonoscopic techniques and equipment, a self-expandable metal stent (SEMS) was introduced to relieve obstructive symptoms, allowing the patient’s general condition to be restored and for them undergo elective surgery. As the use of SEMS placement is growing, controversies about its application in potentially curable diseases have been raised. In this review, the short- and long-term outcomes of different treatment strategies, particularly emergency surgery vs SEMS placement followed by elective surgery in resectable, locally advanced obstructive colon cancer, are described based on the location of the obstructive cancer lesion. Controversies regarding each treatment strategy are discussed. To overcome current obstacles, a potential diagnostic method using circulating tumor DNA and further research directions incorporating neoadjuvant chemotherapy are introduced.

(Improvement of fermented bagasse quality as animal feed by fermentation through administration of sago flour at different levels) ABSTRACT . Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R 1 control (0% sago flour), R 2 (5% sago flour), R 3 (10% sago flour), R 4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P 0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse.
Hydraulic Performance of Asymmetric Labyrinth Side Weirs Located on a Straight Channel

AbstractThis paper details a new design for labyrinth side weirs, which has been tested and analyzed. The proposed geometry for this labyrinth side weir differs from a triangular labyrinth side weir, in that it is asymmetric in plan. The hydraulic behavior of the present labyrinth side weir, with a constant opening length, different weir heights and asymmetric labyrinth side weir included angles has been experimentally investigated in the subcritical situation. Based on the analysis of more than 180 experimental data, an equation for discharge coefficient of the asymmetric triangular labyrinth side weir has been presented. The results show that the discharge coefficient of the asymmetric labyrinth side weir is up to 1.6 and 2.35 times more efficient than a symmetric labyrinth and rectangular side, respectively.
Bile Acid Malabsorption as a Consequence of Cancer Treatment: Prevalence and Management in the National Leading Centre

Simple Summary Bile acid malabsorption is a common albeit a very underdiagnosed gastroenterology condition especially in cancer cohort of patients. Our study, performed at the National leading centre for treatment of cancer, focuses on prevalence and management of bile acid malabsorption in patients reviewed in our specialized clinic. Currently, precise diagnosis and excellent treatments exist for this disease. Abstract The aim was to establish prevalence of bile acid malabsorption (BAM) and management in patients who underwent treatment for malignancy. Retrospective evaluation of data in patients seen within six months (August 2019–January 2020) was carried out. Demographic, nuclear medicine (Selenium Homocholic Acid Taurine (SeHCAT) scan result), clinical (previous malignancy, type of intervention (medication, diet), response to intervention) and laboratory (vitamin D, vitamin B12 serum levels) data were searched. In total, 265 consecutive patients were reviewed. Out of those, 87/265 (33%) patients (57 females, 66%) were diagnosed with BAM. Mean age was 59 +/− 12 years. The largest group were females with gynaecological cancer (35), followed by haematology group (15), colorectal/anal (13), prostate (9), upper gastrointestinal cancer (6), another previous malignancy (9). Severe BAM was most common in haematology (10/15; 67%) and gynaecological group (21/35; 60%). Medication and low-fat diet were commenced in 65/87 (75%), medication in 10/87 (11%), diet in 6/87 (7%). Colesevelam was used in 71/75 (95%). Symptoms improved in 74/87 (85%) patients. Vitamin D insufficiency/deficiency was diagnosed in 62/87 (71%), vitamin B12 deficiency in 39/87 (45%). BAM is a common condition in this cohort however treatments are highly effective.
Estimating Safety Benefits of Road Improvements: Case Based Approach

Improvements to road safety have become a high priority for road authorities due to increasing public awareness and concern of the high social and economic costs of collisions. However, satisfying this priority in an environment of limited budgets and growing fiscal constraints is difficult. It is therefore important to ensure that the funding available for road safety improvements is efficiently utilized. In an attempt to maximize the overall road safety benefits, safety professionals usually invoke a process to evaluate the cost effectiveness of road safety projects. Road safety benefits are normally determined using collision reduction factors (CRFs) that are reported in the road safety literature. However, the results from many previous safety studies are unreliable due to the inability to apply the CRFs to all conditions and because many safety studies suffer from problems with the evaluation methodology and accommodating the random nature of collisions. To resolve these problems, safety analysis software known as the information system for estimating crash reductions (ISECR) has been developed. Information system for estimating crash reductions is an intelligent database that uses a case-based reasoning approach to compile the results from previous road safety research. Information system for estimating crash reductions evaluates the applicability of the results by accounting for site-specific characteristics and the study methodology by assigning a quality score. The system determines the expected CRFs and the range and reliability associated with a safety improvement at a specific location. The evolution of ISECR, a description of current and future enhancements, and the applications for this road safety-engineering tool are the subjects of this paper.
