“Know Your Coffee!” The Cultural Semantics of a Lexico-Syntactic Molecule of English
Authors: Farese Gian Marco
Published: June 2022

This paper presents a cultural semantic analysis of the English syntactic construction ‘know your + noun’ made combining the analytical principles and methods of ethnosyntax (Wierzbicka, 1988, 2003, 2006a) with those of corpus-based discourse analysis (Baker, 2006; Partington et al., 2004). Three main points are made in the paper: (i) ‘know your n.’ constitutes an indissoluble lexico-syntactic molecule of English expressing its own specific meaning; (ii) this construction is both genre-specific and subject to intralinguistic variation; (iii) this construction is quintessentially Anglo, because it reflects Anglo cultural assumptions about personal autonomy informing certain speech practices in English discourse (Goddard & Wierzbicka, 2004; Wierzbicka, 2006b) and defies easy translation in other languages. The analysis is based on the findings of a corpus search in GLOWBE across varieties of English complemented by additional data from the web. The results provide a clear picture of the meaning of ‘know your n.’ and of where it situates within the broad range of know-constructions. Ultimately, the paper emphasises the contribution that corpus-based, empirical discourse analysis can make to the semantics and ethnography of syntax as well as to the study of the interface between syntax, semantics and culture.

Authors: Ito Takamichi , Umemoto Takatoyo
Published: June 2022

This study examined socially shared regulation of learning (SSRL) and motivation processes in a collaborative learning task that required creativity using the ICT tool of mind mapping. Thirty university students formed three groups, collaborating face-to-face to generate creative ideas. The following results were obtained from qualitative and quantitative data using psychological scales and utterance analysis. In the middle phase of the collaborative activity, there was a significant weak-to-moderate positive correlation between socially shared regulation of cognition, self-regulation, co-regulation, and socially shared regulation of intrinsic motivation and a deep level of regulation utterances. Moreover, there were significant weak-to-moderate correlations between behavioral and cognitive engagement, SSRL of monitoring and cognition, and the three modes of motivational regulation. Creative performance was significantly and moderately positively associated with socially shared regulation of cognition and total frequency of utterances in the group. Based on these findings, the implications for practice in university education are discussed from the perspective of socially shared regulation in collaborative learning.

Authors: Gorospe Joanne D.
Published: June 2022

Practice teaching represents authentic experiential learning and culminating experience to better prepare the prospective teachers for actual teaching experience. However, pre-service teachers who go through the practicum have a number of worries and anxieties which could lower their teaching self-efficacy and consequently their performance. This study aimed to determine the relationship between the pre-service teachers’ teaching anxiety and teaching self-efficacy, the possible reasons for such teaching anxiety, and pre-service teachers’ suggestions to lessen, if not totally eliminate it. For this purpose, student-teacher anxiety and self-efficacy scales have been used for data collection as well as interviews among the pre-service teachers. The findings revealed that pre-service teachers’ teaching anxiety significantly relates to their teaching self-efficacy and among the factors of teaching anxiety, classroom management best predicts pre-service teachers’ teaching self-efficacy. It was also found that there is a significant difference between the levels of teaching anxiety of the pre-service teachers depending on their grade level placement. As perceived by the pre-service teachers, the main cause of their teaching anxiety is high expectations from cooperating teachers and students; hence they recommend better planning and preparation for internship.

Authors: Vlaović Zoran , Jaković Marko , Domljan Danijela
Published: June 2022

The health consequences of prolonged sitting in the office and other work chairs have recently been tried to be alleviated or prevented by the application of modern technologies. Smart technologies and sensors are installed in different parts of office chairs, which enables monitoring of seating patterns and prevents positions that potentially endanger the health of users. The aim of this paper is to provide an overview of previous research in the field of the application of smart technologies and sensors built into office and other types of chairs in order to prevent diseases. The articles published in the period 2010-2020 and indexed in WoS CC, Scopus, and IEEE Xplore databases, with the keywords “smart chair” and “sensor chair” were analysed. 15 articles were processed, with their research being based on the use of different types of sensors that determine the contact pressures between the user’s body and stool parts and recognise different body positions when sitting, which can prevent negative health consequences. Analysed papers prove that the use of smart technology and a better understanding of sitting, using various sensors and applications that read body pressure and determine the current body position, can act as preventive health care by detecting proper heart rate and beats per minute, the activity of individual muscle groups, proper breathing and estimates of blood oxygen levels. In the future research, it is necessary to compare different types of sensors, methods used and the results obtained in order to determine which of them are most suitable for the future development of seating furniture for work.

In the past traditionally produced furniture, today enables many different stages to be handled at the same time, through the calculation of variable parameters enabled by computer aided design Thus, designers can make all kinds of changes on their design in a short time. In this paper a parametric approach for rapid assembly design is presented. Rhinoceros software and Grasshopper plugin used for the parameterization process of components and Microsoft Excel used for implementation design. Furniture manufacturers, who will use the parametric design approach, will be able to respond quickly to the changing demands of their customers and will stand out among their competitors.

As a case study, the author has chosen the wardrobe type furniture with several shelves, hanger section, drawer/s has two doors.
Passive Inter-modulation Sources and Cancellation Methods
Authors: Karaca Hakan Murat
Published: June 2022

When two or more signals of different frequencies pass through a nonlinear system, intermodulation distortion (IMD) occurs, resulting in the formation of spurious distortion signals. IMD is most commonly found in active circuits of a radio system, but it can also be found in passive wireless components such as lters, transmission lines, connectors, antennas, attenuators, and so on, especially when transmit power is quite high. Passive intermodulation (PIM) distortion is the name given to the IMD in the latter scenario. With the evolution of radio systems and the scarcity of radio spectrum, PIM interference is being recognized as a potential stumbling block to a radio network's maximum capacity.

This article classifies the PIM sources in BS radio systems into two categories, internal and external sources. Internal sources are the radio's passive components such transmission lines, connections, antennas, and so on. External sources, on the other hand, are passive items that are located outside of the BS antenna but inside the RF signal path, such as metallic and rusted objects in the antenna near eld. The high power current flowing through such passive devices can cause nonlinear behavior, resulting in IMD for both types of sources. Also, a review of PIM mitigation techniques is presented in the article.

Ruang lingkup penelitian ini adalah studi tentang pengaruh kualitas produk dan harga terhadap loyalitas konsumen dengan kepuasan sebagai variabel intervening (studi kasus konsumen bedak marck’s pada mahasiswi Fakultas Ekonomi dan Bisnis Universitas Nias Raya). Tujuan penelitian ini adalah untuk mengetahui pengaruh kualitas produk dan harga terhadap loyalitas konsumen dengan kepuasan konsumen sebagai variabel intervening yang menganalisis pola hubungan antar variabel yang berbentuk sebab akibat dan dengan tujuan untuk mengetahui pengaruh langsung dan pengaruh tidak langsung. Metode penelitian yang digunakan adalah analisis jalur (path analysis). Hasil yang di dapat menunjukan bahwa pengaruh kualitas produk dan harga berdasarkan persamaan struktural pertama kepuasan konsumen baik secara gabungan mau secara parsial dan pengaruh kualitas produk, harga dan kepuasan konsumen persamaan struktural kedua secara signifikan mempengaruhi loyalitas konsumen baik secara gabungan mau secara parsial. Dengan demikian dapat disimpulkan bahwa perusahaan harus mampu memberikan kualitas dan harga produk yang baik untuk menciptakan perasaan puas konsumen terhadap suatu produk karna kepuasan konsumen terhadap kualitas dan harga produk akan membuat konsumen bersifat loyal.

Context: D-Aspartic acid (DAA) is an amino acid found in the brain and reproductive system. Some investigations have reported beneficial effects of DAA on brain function and reproductive system health by increasing testosterone through the hypothalamic-pituitary-gonadal axis. However, its effect on body composition is unknown. Given testosterone's role in muscle growth, this study aimed to evaluate the effect of DAA supplementation on the body composition of trained males. Evidence Acquisition: PubMed, Scopus, Embase, and Web of Science (until 1 August 2021) were searched for this systematic review. Inclusion criteria assumed as clinical trials assessed the effect of DAA on body composition in trained males. After including articles by keywords, the articles were reviewed for meeting the eligibility criteria. Three independent researchers conducted the search and full-text review. Results: Among 134 articles located during the primary search, five articles (47 interventions and 43 controls) were included in the study based on eligibility criteria. All included clinical trials had a low risk of bias. A review of the relevant literature concludes that different doses of DAA (three grams, six grams, 7.12, and 12 grams) in different intervention periods (two weeks, four weeks, and 12 weeks) have no effects on body composition in trained males. Conclusions: DAA supplementation is a low-level booster of testosterone and has no significant effect on the testosterone level in professional male athletes, and cannot alter the body composition.

Background: Doxorubicin is anticancer that is a choice for the treatment of many malignancies. The nature of its toxic effects on the liver and other organs is the harmful character that leads to use with caution. Then, it is necessary to supplement an antioxidant with doxorubicin to reduce its side effects. Objectives: Cichorium intybus (C. intybus) is a plant with hepatoprotective effects. Melatonin is an antioxidant similar to vitamins. We investigated the repairing effects of C. intybus -melatonin together against doxorubicin-induced hepatotoxicity. Methods: Thirty balb/c mice in the weight range of 20 g to 25 g were divided into 5 equal groups of 6 animals each. The groups were as Control: normal saline; DOX: doxorubicin; Chicory: chicory whole plant extract + DOX; Melatonin; melatonin + DOX; Both Chicory-Melatonin + DOX. We assessed histopathology to define necrosis, vacuolar degeneration, and inflammation. In addition, we used immunohistochemistry to evaluate the TNFα proving the rate of inflammation. Results: The mean sum of histological grading in the control group was 0.00 in contrast to severe damage of the hepatic parenchyma grading 11.34 in sum. The mean sum grade of the other groups including Chicory, Melatonin, and Both Chicory-Melatonin were 8.17, 4.18, and 2.49, respectively. We found that the increased liver damage and TNF-α expression induced by DOX could be improved by applying therapeutic care with the coadministration of the C. intybus extract and Melatonin. Conclusions: Chicory and Melatonin have a healing ability against doxorubicin-induced hepatic lesions.

: Adolescents do not have adequate safe traffic behaviors. This cross-sectional study investigated safe traffic behaviors of 414 male high school students of Hamadan, Iran, randomly selected using the multistage sampling method in 2020. This study used a researcher-made questionnaire based on the theory of planned behavior about safe traffic behaviors with Cronbach’s alpha coefficient of 0.95, content validity ratio of 0.70, and content validity index of 0.85. There was a strong positive correlation between safe traffic behaviors with perceived behavioral control and intention. Adolescents can be influenced to internalize behavioral safety precursors that can lead to a sustained increase in safe traffic behaviors and the prevention of road traffic injuries.
