Hungarian Secondary School Students’ Extramural English Interests: The Development and Validation of a Questionnaire

Leisure time (or extramural) English activities have been an important resource in foreign language teaching and learning for decades. They may provide a plethora of EFL input, thus contributing to learners’ second language development even from an early age. The incorporation of extramural English activities into EFL lessons still remains rare, focusing only on mainly songs and short videos from YouTube. Despite this, an array of different extramural English activities is available, which could and should be exploited in EFL lessons in order to support second language acquisition. In the Hungarian context, little research investigates the potential impact of extramural English activities on the foreign language learning process, let alone the different individual learner differences. The aim of the present paper is to introduce a pilot study reporting on the development and validation process of a research instrument. The main aim of the study is to obtain insights into Hungarian secondary school students’ extramural English interests and individual learner differences, namely motivation, anxiety, willingness to communicate and additional variables affecting these learner differences. The preliminary results of the study show that Hungarian EFL learners engage in several extramural English activities on a regular basis and participants seem to show a relatively positive attitude to the use of English language subtitles. Furthermore, certain extramural English activities seem to have a positive impact on extramural motivated language use. It is hoped that the findings of this study will contribute to a better understanding of Hungarian secondary school EFL students’ engagement habits in extramural English activities, which may prove useful for EFL teachers planning to incorporate their students’ extramural interests into their EFL lessons

Baikal-GVD: status and prospects

Baikal-GVD is a next generation, kilometer-scale neutrino telescope under construction in Lake Baikal. It is designed to detect astrophysical neutrino fluxes at energies from a few TeV up to 100 PeV. GVD is formed by multi-megaton subarrays (clusters). The array construction started in 2015 by deployment of a reduced-size demonstration cluster named "Dubna". The first cluster in its baseline configuration was deployed in 2016, the second in 2017 and the third in 2018. The full scale GVD will be an array of ~10000 light sensors with an instrumented volume of about 2 cubic km. The first phase (GVD-1) is planned to be completed by 2020-2021. It will comprise 8 clusters with 2304 light sensors in total. We describe the design of Baikal-GVD and present selected results obtained in 2015-2017.Comment: 9 pages, 8 figures.

The effects of danofloxacin and tilmicosin on peripheral neutrophils in healthy cattle, on peripheral neutrophils in cattle with induced Pasteurella haemolytica pneumonia, and on body temperature measured via radiotelemetry in cattle with induced Pasteurella haemolytica pneumonia

Three studies are described in this report. In the first study, the effects of danofloxacin and tilmicosin on neutrophil function were examined in healthy mixed-breed weaned beef heifers. Neutrophils were isolated from peripheral blood samples pre- and post-treatment. The neutrophil function assays performed were: random migration under agarose, Cytochrome C reduction, iodination, Staphylococcus aureus ingestion, chemotaxis under agarose, and antibody-independent and antibody-dependent cell-mediated cytotoxicity. The results suggest that at therapeutic drug concentrations, danofloxacin and tilmicosin have little clinically significant effect on bovine neutrophil function. In the second study, a model was developed for the induction of pneumonic pasteurellosis (using 6 x 109 CFU of a log-phase culture of Pasteurella haemolytica intrabronchially) in weaned, pre-conditioned beef calves that consistently produced rectal temperatures of at least 40°C 24 hours after bacterial challenge, a clinical score of ≥1, and measurable lung consolidation. In the third study, Pasteurella pneumonia was induced in weaned beef heifer calves using the model from the second study, and calves were treated with danofloxacin or tilmicosin. Neutrophils were collected at 3, 24 and 48 hours after treatment. Neutrophil function assays were as performed in study 1, and apoptosis was determined using a cell death detection kit. The results suggest that danofloxacin and tilmicosin have no clinically significant effects on neutrophil function or apoptosis. There were also no significant differences in percent lung consolidation among treatments. Significant differences were found between non-challenged calves and the challenged non-treated calves in several neutrophil assays, which were attributed to an effect of the Pasteurella infection. Body temperature was also examined in this study via intravaginally implanted radiotransmitters. Temperatures were monitored prior to challenge until necropsy at 72 hours after treatment. The areas under the curve of the temperature-time plot (and over a baseline temperature established for each animal) calculated for 3-hour intervals were not significantly different for any of the time intervals when challenged animals were compared. Analysis of the mean 3-hour interval temperatures showed significantly higher temperatures for saline-treated as compared to antimicrobialtreated animals for the majority of the time intervals, but no differences were found between the danofloxacin- or tilmicosin-treated animals

Injection-site lesion prevalence and potential risk factors in UK beef cattle

Injectable veterinary medicinal products (VMPs) are widely used in cattle in the UK, and in particular vaccines are often used on large numbers of animals in the herd. The formation of injection-site lesions (ISLs) is a risk when using injectable products and has potential consequences for meat quality, animal welfare and beef industry income. This study used carcase observation in four abattoirs in England to determine ISL prevalence in beef cattle. Additionally, a questionnaire survey was used to investigate vaccination technique among UK beef farmers. The ISL prevalence was 4.1 per cent (95 per cent CI 3.4 per cent to 4.9 per cent). A potential difference between sites being used for vaccination and the distribution of ISLs on carcases suggested that factors other than vaccination were contributing to ISL incidence. Questionnaire responses highlighted deficits in good vaccination practices such as using the recommended site of injection and needle hygiene. The role of the veterinarian in knowledge transfer is crucial in providing practical injection advice when prescribing vaccines and other VMPs. This study identified factors to address when aiming to reduce ISL formation in UK beef animals

Extramural English Activities and Individual Learner Differences. A case of Hungary

In an era where the ubiquity of the English language intersects seamlessly with global entertainment, today’s youth naturally absorb the language while engaging in leisure activities. Delving beyond conventional pedagogical boundaries, this book illuminates how extramural activities, from cinematic experiences to digital gaming, can be exploited as resources for learning English. Employing a rigorous empirical framework, the present research project uncovers evidence that learners who engage in extramural English activities demonstrate higher English learning motivation, reduced English speaking anxiety, and enhanced willingness to communicate in English. Written for language professionals and researchers, this synthesis of empirical results aims to enrich the discourse on English as a Foreign Language learning and teaching. By unravelling the relationship between leisure, motivation, and individual learner differences in general, this book aims to provide readers with important research findings relevant in current foreign language education

Second language learning motivation, life-long learning and 21st century skills in today\u27s globalized world: A validation study

Knowledge production in today’s world presupposes skills necessary for successful knowledge construction and knowledge update. Such skills include English as a foreign language (EFL), life-long learning and 21st century skills. This study presents a quantitative pilot study (N=200) that examines the relationship between EFL learning motivation, communication in L1 and L2, some aspects of life-long learning and certain 21st century skills. The paper seeks to explore what this relationship is like and in what way these factors are connected and how they potentially impact one another. The study presents the validation of the instrument used for the research, and reports some of the preliminary findings. Based on the results, it is concluded that the ideal L2 self is a predictor of L2 learning motivation, willingness to use dictionaries and cooperation during EFL classes. The results also indicate that participants exhibit the necessary ICT and L1 skills for their studies of EFL, and positively relate to communicative situations with native and non-native speakers of English
