Effect of Steel Fiber on Plastic Hinge Length of Concrete Columns: Buckingham Theory Application
Authors: Tavio . , Sabariman Bambang , Widodo Slamet
Published: June 2024

The accuracy of designing the performance of concrete structures nowadays not only depends on the use of standard materials (cement, sand, and gravel) for certain concrete strengths but also on the accuracy of using additional materials for concrete, such as steel fiber. The use of steel fiber not only can improve the performance of concrete structures to behave in a ductile manner but can also form plastic hinges according to design purposes. The design of the axial load of Pa=0.121.Ag.f'c is based on the prediction of the column’s axial capacity. The columns were designed to behave in a flexural manner. As predicted, the lengths of the plastic hinges were found not too long. Controlling the length of plastic hinges in the design of structural concrete members is necessary to avoid excessive displacements. The control is mainly related to the prediction of the plastic hinge length. Thus, in this case, a plastic hinge length formula is required. In the study, the length of the plastic hinges of columns, which are confined with square stirrups and reinforced with steel fiber with Vf = 0%, 0.5%, 1%, 1.5%, and 2%, is proposed. This plastic hinge length formula is proposed after all column test specimens have met the displacement ductility requirement of mD>4, meaning that all test specimens are defined as very ductile. Doi: 10.28991/CEJ-2024-010-05-03 Full Text: PDF

Dåajmijes vuekie: A Sami Aesthetic Paradigm
Authors: Kappfjell Lena , Gaski Harald , DuBois Thomas
Published: June 2024

The South Sami concept of dåajmijes vuekie is used to discuss a nuanced system of evaluative  norms operating in Sami culture, past and present, in relation to objects, behavior, and activities. Where Western aesthetics may focus on surface appearance, dåajmijes vuekie emphasizes effective action in relation to practical needs, social interaction, and ethics. The authors suggest that evaluative norms associated with Sami traditional knowledge and activities can provide valuable insights for understanding not only Sami traditional life but also works of contemporary Sami artists and writers who draw on Sami cultural norms in conscious ways.

Bees, Butterflies, and Beyond the Diverse Pollinators, an Essence for the Reproductive Success of Flowering Plants
Authors: Ammir Hassan , Shamiya Hassan , Mohd Abdul Nasir
Published: June 2024

Pollinators are very critical when it comes to the reproductive success of plants. They promote outbreeding which holds immense significance in the era of global climate change. It allows the plants to become fertilized, to produce seeds, fruits, and eventually new plants. They are instrumental in the sustainability of our ecosystem. Thus, there is an essential need to study these pollinators to understand how, during the course of evolution, they have co-evolved with the flowering plants to shape floral architecture and community dynamics thriving in the vicinity. In this mini-view, we shall focus our discussion on some of the animal pollinators, the dwindling diversity of animal pollinators, and various associated pollination syndromes.

Factors of Ethnic Distance: A Systematic Scoping Review
Authors: Šlebir Miha , Zupančič Rok
Published: June 2024

Identifying factors determining ethnic distance is a perennial quest in ethnic studies. This is important not only from a theoretical perspective but also as a basis for developing practical interventions aimed at decreasing ethnic distance, which could, in turn, lead to increased tolerance and social peace. Building on existing research, we conducted a systematic scoping review of 30 studies to identify prevalent factors and variables that significantly impact individuals’ ethnic distance. According to our study, the most relevant variables are gender, education, income, age, interethnic contact, war experience, following news in the media, religious commitment, religious denomination, and political orientation. The analysis has shown that these variables can be grouped into four distinct factors: sociodemography, exposure, religion, and politics. However, none of the factors and variables identified were found to be universally applicable, as the cause of ethnic distance is multifactorial and context-dependent. We mapped the characteristics of existing studies, focusing on any indication of psychological mechanisms driving the changes in interethnic (in)tolerance. Most of the studies reviewed were based on the Bogardus scale, a commonly used tool for measuring ethnic distance.
Validation of a learning progression for sound propagation in air
Authors: Costa João Paulo , Baptista Mónica , Amantes Amanda , Conceição Teresa
Published: June 2024

This study was conducted with 37 11th grade secondary school students and had as its focus to verify the different levels of sophistication in students’ explanations regarding the propagation of sound in air. A pre- and a post-test were conducted after a one-month intervention, focusing on learning about sound propagation in air. Data analysis allowed for comparing the progressions in the sophistication of students’ explanations and validating the proposed categorical structure of the hierarchical levels of learning progressions (LPs). The validity was confirmed by the consistency of the category hierarchy, assessed in terms of the difficulty coefficients of LPs levels, which were distinct in the two tests but maintained the established order in the construct maps. In the pre-test, the more sophisticated levels of LPs were not elucidated, but after instruction, in the post-test, there were explanations at all levels. The results also reveal the importance of instruction focused on LPs, so that students can present more sophisticated explanations, and their utility for future investigations using this approach.
How teachers’ reading of competency-oriented national mathematics curriculum documents relates to their sense-making of reform messages
Authors: Song Chang-Geun , Lee Kyeong-Hwa
Published: June 2024

Although implementing a competency-oriented national mathematics curriculum is a global trend, limited studies have explored how teachers read their national mathematics curriculum documents and make sense of the competency-oriented reform messages present in these documents. This study investigated the patterns of teachers’ reading of the competency-oriented national mathematics curriculum documents and how the reading relates to the teachers’ sense-making of the reform messages in the documents. Participants included 18 in-service mathematics teachers who took part in a graduate course designed to support interpreting the recently revised competency-oriented national mathematics curriculum documents in Korea. Content analysis of the teachers’ writings regarding their interpretations of the documents revealed three types of reading: identifying, clarifying, and extending competency-oriented curriculum messages. Reading accompanied by ‘clarifying’ formed a dialogic relationship between the teachers and the curriculum, leading to accommodation of competency-oriented messages. Conversely, reading accompanied by ‘identifying’ but without ‘clarifying’ led to a monologic relationship between the teachers and the curriculum, resulting in the assimilation of competency-oriented messages. We conclude by suggesting that teachers’ nuanced interpretations of competency-oriented national mathematics curriculum documents may contribute to professionalism in handling the curriculum.

Authors: Mohammed Ibrahim Abba , Bello Ahmed
Published: June 2024

Due to rapid technological advancement that continues to permeate almost all facets of the education sector, video learning has been explored to enhance performance, but most researchers do not incorporate flipped classroom in mathematical videos, which affects the teaching and learning of the subject in Nigeria. This study checked the effectiveness of video learning in flipped and flipped collaborative classroom on mathematics students’ achievement and retention. Using a randomized controlled trial with repeated measures approach, 70 senior secondary school students were purposively sampled from two private secondary schools in Gombe State, Nigeria, out of which they were randomly assigned into two experimental groups: video learning flipped classroom and video learning flipped collaborative classroom (VLFCC). Data was obtained using a 30-item mathematics achievement test, which was validated and pilot-tested (r=0.93). Results were computed using descriptive statistics and two-way mixed design repeated measures analysis of variance. Findings revealed that while the students’ within subject performance improved tremendously in the post-test after the four-week treatment, the students in VLFCC performed better in both achievement (F[1, 69]=1,576.362, p=0.000, effect size of (ηp2) of 0.954) and retention (F[1, 69]=114. 119, p=0.000, with an effect size (ηp2) of 0.785. The finding has some implications for it exposes mathematics teachers, researchers, and policy makers to the credence of deploying video learning in flipped collaborative classroom to improve students’ performance by engaging students in collaborative learning in addition to watching pre-class videos, where students discuss in small groups in order to learn through observation, imitation, repetition and behavior modeling, thus making them to learn at their pace in order to construct their own knowledge.

Published: June 2024

This research study presents findings of the analysis of determining the domestic water usage in Yolde-Pate area of Yola South LGA of Adamawa State Nigeria. During the recce survey and final survey; the sources of domestic water were identified and mapped out in the study area which include: 127 Industrial borehole, 16 hand-pumps, 6 well water and 1 public tap. Domestic water usage moves in hand with its source and accessibility this is where Nearest Neighbor Analysis NNA was used and its summary depicts the following; z-score of 0.205792265731; which means the pattern does not appear to be significantly different than random; which is fairly recommendable. Mean Distance is 51.1643 Meters, Neighbor Ratio is 1.024, and p-value: 0.836953. This was achieved due to the highly precision DGPS used in determining the spatial positions of each of the 150 XYZ points of each water source location and digitally mapping out the whole study area. Then 600 well-structured questionnaires that were randomly distributed within the study area with the respondent’s responses largely related to the analysis of determining domestic water usage were retrieved and analyzed with the End User Analysis (EUA)Technique. The results show that the total volume of water used daily per house ranges from 52,247 to 78,856 liters for each house hold with a range of 54.53liters to 67.69 liters of water consumption per individual in a day; which fall short of WHO standard of 120 liters. However the EUA based on the population density of the study area reveals: first for the high density areas, which has 3 wards Gadawalowol Yolde Patte ward, Jalingo Yolde Patte ward and Chaka Midari ward with a mean population of 1187, mean household size of 4.67 individuals, 71500 liters as the mean total of consume water daily, 60.35 as the mean per capita water consumption per day individually while standard still remains 120 liters and the mean total of daily demand is 142,440 liters; which shows deficit of what is needed. For the medium density areas with an average population of 1093 which are made up of 2 wards depicts 61100 liters as the mean total of water consumed daily by each household, 55.86 liters was consumed by an individual with a daily mean demand of 131,160 liters. While the low-density areas which mainly is occupied by the Sabonpegi Yolde Patte ward residence has a population of 876, total water consumption per household of 52,247liters, Per Capita Water Consumption (liters per day) is 59,64liters while its water daily demand is 105 120 liters; similarly, a shortage of what is demanded and WHO standard exist also in the medium and low-density areas. Recommendations were then spelt out to improve water consumption and usage with well design accessibility structure to improve well-being of the people in this study area.

Scham – (k)ein Thema für die Männer*beratung
Authors: Kling Dominik
Published: June 2024

Im Kontext der Praxis und Theoriebildung zur Männer*beratung erfährt die Verbindung von Scham und Männlichkeit(en) bislang nur unzureichend Berücksichtigung, wenngleich die emotionstheoretische Potenz von Scham und Beschämung für die Aufrechterhaltung und Durchsetzung von (hegemonialen) Männlichkeitsvorstellungen, aber auch das Transformationspotenzial derselben, eine hohe Relevanz aufzuweisen scheinen. Der vorliegende Text möchte hierauf aufmerksam machen und diesbezüglich Impulse für die Theorie und Praxis der Männer*beratung liefern. Hierzu werden kurz der Diskurs zu Scham sowie ein Verständnis von Männer*beratung skizziert. Daran anschließend werden sowohl Zusammenhänge zwischen männlicher* Sozialisation, Subjektivierung und deren Bewältigung, sowie Anrufungen an Männlichkeit(en) im Kontext von Scham und Beschämung, als auch deren Verarbeitung diskutiert. Darauf basierend erfolgt die Betrachtung beraterischer Implikationen, Potenziale, aber auch Sperrungen für Berater*innen und Klienten* sowie die Inblicknahme von Reflexionsaspekten zur beraterischen Schamsensibilität und -kompetenz.

Based on a conceptual coding framework, the word problems were coded accordingly. The results revealed a significant representation of combine and compare structures across all contents in both the textbooks and accompanying workbooks. In particular, the lack of word problems involving change structure suggests an unequal distribution of the semantic structures. Based on the findings, it is recommended that educators and textbook authors to be aware in providing students the opportunity to be equally exposed to the various semantic structures in the teaching and learning of both the addition and subtraction word problems.

This study adopted a qualitative ethnographic approach to explore the factors influencing English as a foreign language undergraduate and graduate students’ emoji use in X (previously Twitter). To this end, a convenient sample of fifteen Twitter-using Saudi female undergraduate and graduate students at a Saudi University was recruited. Semi-structured interviews were used as data collection methods. The study revealed that there are some factors influencing emoji use. According to the study results, age impacts both emoji frequency and meaning. Moreover, it was found that different personas were exhibited by some participants, suggesting that they are much less reserved in English, which could influence their emoji use. Additionally, the results showed that different religious beliefs and cultural backgrounds can shape an individual’s perception and interpretation of emojis. The topic of discussion and the gender of the interlocutors were also mentioned as additional factors. The study thus provided insights into a rarely investigated area of research, which is the factors influencing English as a foreign language undergraduate and graduate students’ emoji use in online postings. Additionally, the study highlights the need to make an emoji function taxonomy, one that is adaptable both in versatility and applicability. Finally, the findings invite all academics to reconsider the rigidity of their anti-emoji beliefs, particularly relating to the students’ expected email etiquette practices.

Sistem kepercayaan dan budaya yang terdapat di masyarakat tidak dapat dipisahkan dari tatanan kehidupan masyarakat. Salah satu fenomena yang sampai saat ini terjadi yaitu mempercayai pengobatan alternatif untuk menghindari penyakit tertentu yang tidak terdeteksi secara medis dan tidak masuk akal sehat manusia, selain itu juga terkadang penyakit biasa yang jika melalui pengobatan medis akan mengeluarkan biaya yang mahal, maka tidak sedikit masyarakat cenderung lebih memilih alternatif pengobatan lain yang biayanya tidak terlalu mahal. Masyarakat tertentu masih percaya untuk mengobati penyakit tersebut dengan menggunakan metode rajahan, ada beberapa motif dari masyarakat yang tetap yakin untuk memilih metode rajahan sebagai alternatif pengobatan seperti, pernah berhasil sembuh, tradisi keluarga, serta budaya yang masih melekat pada masyarakat tertentu yang meyakini hal tersebut. Rajahan merupakan suatu gambaran atau suratan yang diyakini mengandung kekuatan gaib atau daya magis yang kuat. Rajahan berupa azimat yang ditulis dalam bahasa arab baik tertulis ayat-ayat al-Quran maupun angka-angka arab yang berbentuk pada suatu lembaran maupun benda-benda tertentu. Tujuan penelitian ini yaitu (1) rajahan dan pengobatan, (2) proses rajahan dalam pengobatan, dan (3) dampak pengobatan rajahan. Adapun metode yang digunakanya itu kualitatif dengan analisis deskriptif dengan teknik pengumpulan data wawancara dan studi literatur. Hasil penelitian ini menunjukkan pada proses rajahan dalam pengobatan terdapat syarat, ketentuan, dan media yang berbeda-beda serta penggunaan tulisan arab baik berupa ayat-ayat al-Quran dan doa-doa untuk kesembuhan yang akan diaplikasikan pada lembaran atau benda tertentu untuk kesembuhan orang yang sedang sakit. Dampak dari rajahan dalam pengobatan memberikan kesembuhan kepada orang-orang yang berobat melalui rajahan. Kesembuhan tersebut membuat kepercayaan di dalam masyarakat meningkat terhadap pengobatan dengan rajahan dibandingkan pengobatan secara medis.Kata kunci: petunjuk penulisan; jurnal pertanian; template artikel
