Language learning strategies in focus: exploring their utilization by college student-athletes
Authors: Huang Shu-Hsiu , Tsai Kuei-Lan 
Published: May 2024

Abstract
This study explores the specific language learning strategies (LLS) employed by student-athletes in Higher Education institutions in Taiwan. Given these student-athletes’ challenges in balancing academic and athletic commitments, understanding their adoption of LLS provides valuable pedagogical insights. This quantitative research gathered 150 responses, considering variables such as academic year, gender, duration of English study, and athletic specialization. Our findings indicate a moderate overall LLS usage, with a pronounced preference for metacognitive strategies. Strategies such as watching English shows and actively engaging in conversations were particularly favored. Conversely, kinesthetic and mnemonic approaches were less popular, such as acting out words or using rhymes. Delving deeper into the data, there were limited gender-based differences in LLS adoption. However, athletic specialization significantly influenced LLS preferences. Especially, martial arts or combat sports athletes had the highest LLS mean scores across all categories. These results highlight the distinct LLS preferences among Taiwanese student-athletes and suggest potential pedagogical adaptations to enhance their language learning experiences.
Investigating Chinese university students’ foreign language enjoyment and anxiety in the EFL class
Authors: Wu Huashan 
Published: May 2024

Abstract
Emotion research in second language acquisition has flourished under the growing influence of Positive Psychology in recent years. The present study focuses on foreign language enjoyment (FLE) and foreign language classroom anxiety (FLCA) of 263 Chinese undergraduates in relation to learner variables as well as the sources of enjoyment and anxiety in the English class. Surveys with scales and open-ended questions were applied to collect data. Quantitative analysis revealed that learner variables, such as participants’ gender and their year of university, affected their FLCA but not FLE, while participants’ perception of their English levels was significantly linked to both FLE and FLCA. Furthermore, the uniqueness of Chinese FL learners’ FLE and FLCA was uncovered from participants’ narratives of their emotional experiences in College English class. The results of open-ended questions clarified that interesting teaching content, students’ good performance and progress, and well-designed classroom activities were effective boosters for foreign language (FL) learners’ enjoyment. Moreover, public speaking, the teacher’s random call, and peer pressure were closely related to spikes in students’ in-class anxiety. This study concluded with implications for EFL teaching, along with directions for further research.

Published: May 2024

Abstract
The geometrical and hydraulic parameters have a great impact on the mass transfer characteristics of annular centrifugal contactors. The objective of this study is to evaluate the mass transfer performance of a single annular centrifugal contactor by applying the computational fluid dynamics informed compartment modelling approach. In the study, a steady state compartment model of an annular centrifugal contactor is developed in gProms general purpose process modeller by using the hydrodynamic parameters obtained from computational fluid dynamics simulations performed in OpenFOAM with the GEneralised Multifluid Modelling Approach (GEMMA). The mass transfer rate predicted by the developed compartment model is compared with data obtained from uranium extraction with Tributyl Phosphate experiments performed with a laboratory-scale annular centrifugal contactor. Uranium concentrations in the organic and aqueous outlets and the mass transfer rate evaluated by the developed compartmented contactor model are in good agreement with the experimental data. The results reveal that the use of a hydrodynamic-informed compartment modelling approach raises the possibility of designing full-scale annular centrifugal contactors without the need for detailed computational fluid dynamics simulations and the prediction of mass transfer performance of the whole system from laboratory scale experiments.

Abstract
Previous studies tend to not only assess principals’ demographic variables but also use other dependent variables, such as administrative effectiveness, job performance, and student achievement. In the literature, principals’ demographic qualities and the misuse of material capital have been under-assessed. This study used a quantitative approach to investigate the demographic attributes of principals and the abuse of school material capital in secondary schools. Using a questionnaire, data were gathered from 667 secondary school administrators in Cross River State, Nigeria. The findings revealed significant differences in the misuse of school material capital by principals of different ages, professional qualifications, and years of experience. However, major disparities between male and female principals were not identified. More specifically, principals who were older, seasoned, and possessed bachelor’s and Master of Education degrees were efficient managers of school material capital. A high rate of misuse was found among principals who were younger and inexperienced than their counterparts who were young, less experienced, and possessed a postgraduate diploma in education, as well as other professional academic qualifications unrelated to the field of education (e.g., HND, BSc, BA, and MSc). Based on these findings, key implications for quality service delivery and administrative effectiveness were discussed.

Published: May 2024

Abstract
Quantum photonic integrated circuits, composed of linear-optical elements, offer an efficient way for encoding and processing quantum information on-chip. At their core, these circuits rely on reconfigurable phase shifters, typically constructed from classical components such as thermo- or electro-optical materials, while quantum solid-state emitters such as quantum dots are limited to acting as single-photon sources. Here, we demonstrate the potential of quantum dots as reconfigurable phase shifters. We use numerical models based on established literature parameters to show that circuits utilizing these emitters enable high-fidelity operation and are scalable. Despite the inherent imperfections associated with quantum dots, such as imperfect coupling, dephasing, or spectral diffusion, we show that circuits based on these emitters may be optimized such that these do not significantly impact the unitary infidelity. Specifically, they do not increase the infidelity by more than 0.001 in circuits with up to 10 modes, compared to those affected only by standard nanophotonic losses and routing errors. For example, we achieve fidelities of 0.9998 in quantum-dot-based circuits enacting controlled-phase and – not gates without any redundancies. These findings demonstrate the feasibility of quantum emitter-driven quantum information processing and pave the way for cryogenically-compatible, fast, and low-loss reconfigurable quantum photonic circuits.

Soziale Herkunft, Sportengagement und Bildungsaspirationen von Grundschulkindern
Authors: Gehrmann Sebastian 
Published: May 2024

Zusammenfassung
Der vorliegende Beitrag untersucht den Zusammenhang zwischen der sozialen Herkunft, der Sportpartizipation und dem potentiellen Bildungserfolg in Form von Bildungsaspirationen bezüglich des Übergangs in die Sekundarstufe I von Grundschulkindern in Deutschland. Dazu werden Daten von insgesamt 1.860 Befragten der World Vision Kinderstudie 2018 im Sinne einer Sekundäranalyse mit Hilfe der binär-logistischen Regressionsanalyse ausgewertet. Zunächst zeigt sich, dass die Wahrscheinlichkeit eines häufigen allgemeinen Sporttreibens stark von der finanziellen Situation der Herkunftsfamilie geprägt ist. Diese beeinflusst auch die Wahrscheinlichkeit, dass das Kind in einem Sportverein aktiv ist, welche zudem auch bei einem hohen Bildungsabschluss der Eltern erhöht ist. Weiterhin ist es ein bemerkenswerter Befund, dass ein häufiges Sporttreiben auch unter Kontrolle der schulischen Leistung und der sozialen Herkunft die Wahrscheinlichkeit erhöht, dass ein Kind eine Aspiration für das Gymnasium statt für eine andere Schulform aufweist.
Suanzaoren decoction exerts its antidepressant effect via the CaMK signaling pathway

Published: May 2024

Abstract
Calmodulin-dependent protein kinases (CaMKs) are widely regarded as “memory molecules” due to their role in controlling numerous neuronal functions in the brain, and the CaMK signaling pathway plays a crucial role in controlling synaptic plasticity. Suanzaoren decoction (SZRD) can improve depression-like behavior and thus has potential benefits in the clinical treatment of depression; however, its mechanism of action is not fully understood. In this study, we found that key proteins in the CaMK signaling pathway were regulated by the decoction used to treat depression. The purpose of this research was to ascertain if the SZRD’s therapeutic efficacy in the treatment of depression is associated with the modulation of key proteins in the CaMK signaling pathway. A rat model of depression was created by exposing the animals to chronic, unexpected, mild stress. Model rats were given intragastric administration of SZRD or fluoxetine every morning once a day. Protein and mRNA relative expression levels of CaM, CaMK I, and CaMK IV in the hippocampus were measured by Western blot, quantitative polymerase chain reaction, and immunohistochemistry in the hippocampus. Our findings demonstrated that SZRD significantly improved the mood of depressed rats. This indicates that SZRD, by modulating the CaMK signaling system, may alleviate depressive symptoms and lessen work and life-related pressures.
A Structural Model of Manager-Subordinate Communication and Job Performance
Authors: Akpor-Robaro M.O.M 
Published: May 2024

The paper presents a model of the communication relationship between managers and subordinates to explain the complex nature of the interactive process of communication by superior and subordinate; and the link with job performance. The model consists of two main types of information paths, the instruction path and the feedback path. Both subordinate and manager give feedback while instruction is strictly the domain of the manager. An influence path is also indicated which links communication with job performance, with job satisfaction as an intermediary variable between communication and employee job performance. The model posits that communication between the manager and subordinate is interactive and circular in nature, and that communication is equal and reciprocal, i.e. both manager and subordinate are equally engaged as sender and receiver. It was considered that feedback in communication relationship between the manager or supervisor and the subordinate is critical to job performance by the subordinate because it allows the subordinate to be involved in the decision process, and therefore, makes him more receptive to the directives/instructions as he feels his opinion is being taken into account, and consequently, strives to meet performance expectations.
Lithuanian Conceptual Colour–Emotion Associations in the Global Context of 37 Nations
Authors: Jonauskaitė Domicelė 
Published: May 2024

Red with anger or green with envy – such metaphors link colours and emotions. While such colour metaphors vary across languages, conceptual associations between colours and emotions have many cross-cultural similarities. Here, we took published data from 8615 participants (2172 men) coming from 37 nations (i.e., Austria, Azerbaijan, Belgium, China, Colombia, Croatia, Cyprus, Egypt, Estonia, Finland, France, Georgia, Germany, Greece, India, Iran, Israel, Italy, Japan, Latvia, Lithuania, Mexico, Netherlands, New Zealand, Nigeria, Norway, Philippines, Poland, Russia, Saudi Arabia, Serbia, Spain, Sweden, Switzerland, Ukraine, United Kingdom, and United States) and analysed Lithuanian (n = 217) associations between colour terms and emotion concepts. Lithuanians had many associations, the most frequent being red–love, yellow–amusement, yellow–joy, and black–sadness (all endorsed by > 60% of participants). While Lithuanians associated more emotions with colours than the other participants, the Lithuanian pattern of these associations was highly similar to the global pattern (r = .92). When compared to each other nation individually, colour–emotion association pattern similarities ranged between .65 and .89. Lithuanian patterns were the most similar to the Russian and the least similar to the Egyptian ones. Crucially, such similarities could be predicted by linguistic but not geographic distances. Nations speaking languages linguistically closer to Lithuanian also displayed more similar colour–emotion association patterns. These results support universality of colour–emotion associations and point to small but meaningful cultural differences (e.g., red represented love more strongly than anger for Lithuanians but not globally). Future studies should look whether colours can modulate emotions, or whether such associations are purely abstract.

Published: May 2024

AbstractAlgebraic cryptanalysis is a cryptanalysis method that aims to exploit the algebraic structure of an encryption algorithm to obtain the secret key. Algebraic cryptanalysis becomes interesting because it uses a small amount of known plaintext, which in real life very few known plaintexts are available. Algebraic cryptanalysis has previously been performed on several block cipher algorithms and public key lattice-based algorithms. In this study, DES and NTRU were chosen as the objects of algebraic cryptanalysis. This research aims to compare algebraic cryptanalysis on DES and NTRU in terms of their applicability, and to what extent algebraic cryptanalysis can be successful in obtaining keys.Keywords: Algebraic Cryptanalysis; DES; NTRU; polynomial equation.

Authors: Ariyani Ni Wayan , Sri Erawati Ni Luh Putu 
Published: May 2024

Introduction: Nutrient intake for pregnant women was associated with the health status of young children from infancy to adolescents. Antenatal education increases the awareness of nutrient importance for pregnant women. The purpose of this study was to describe the nutritional consumption of pregnant women in terms of the method of antenatal education.
Methods: Cross-sectional study involving 150 pregnant women in Gianyar Regency. They were selected using a cluster random sampling technique. Nutrition consumption data was collected using a 24-hour food recall form. The first interview was conducted on workdays to collect the sociodemographic and obstetric data, the data on the implementation of antenatal education, and 24-hour dietary recall. The second interview was conducted on the weekend, to collect the data on a 24-hour dietary recall.
Results: The results showed that there was no significant difference (p>0.05) in the average consumption of macro and micronutrients for pregnant women in terms of antenatal education methods. The level of consumption of macro and micronutrients was almost all below the nutritional adequacy rate, only protein consumption was in accordance with the nutritional adequacy rate. The results of the analysis of factors related to nutritional consumption showed that there was a significant relationship (p=0.021) between the education factor with calcium consumption. Age, occupation, and gravida factors were not related to the nutritional consumption of pregnant women.
Conclusions: The conclusion of this study was no difference in the nutritional consumption of pregnant women in terms of antenatal education methods. The consumption of macro and micronutrients for pregnant women was almost all below the nutritional adequacy rate
