Engaging Students More Effectively with Case Studies: A Backwards Case Creation Assignment
Authors: Knapp Darin J.
Published: May 2022

Instructors frequently use case studies in teaching. These approaches have demonstrated effectiveness in student learning. With new emphasis on increasing student investment in the learning process in higher education, examining more effective uses of case studies in family science courses is important. The instructor of a senior-level undergraduate course in family science used a backward course design perspective to create a novel assignment using case study analysis. Students in an undergraduate family science class were assigned to write fictionalized case studies incorporating course content as an assessment of their knowledge instead of writing traditional summative research papers to demonstrate competency. The course instructor gathered student feedback specific to this assignment. Feedback was overwhelmingly positive, with 100% of participating students reporting it was an effective assignment for learning content and 92% reporting the assignment should be included in future versions of the course. Student response data yielded detailed, positive feedback about effective student learning and engagement. Considerations for using this approach to construct assignments are discussed, as are future directions for empirically examining this assignment.
Synchronous Videoconferencing: Social Presence and the Engagement of Different Learners in a Blended Family Studies Course
Authors: Kennedy Heather R. , Do Kieu Anh
Published: May 2022

Blended learning allows instructors to retain some face-to-face activities while integrating additional online components to meet demands of a new generation of learners. Yet student disengagement and isolation continue to present challenges to effective course design. Technology adaptation, specifically synchronous videoconferencing, can facilitate student engagement and promote social presence, both of which have been linked to various learning outcomes. There has been insufficient research on person-centered approaches to inquiry, specifically the roles of students (e.g., characteristics) in technology integration. This mixed methods study in a blended family science course explored students’ perceptions of contributions from videoconferencing with regard to social presence. Three profiles of students (i.e., receptive, ambivalent, and resistant) emerged in relation to technology integration and social presence. Quantitative results also found significant differences between these profiles on perceptions related to social presence.
“I really believe we can change people’s lives”: Family Life Educators’ beliefs
Authors: Troilo Jessica
Published: May 2022

This qualitative project sought to understand how 53 Family Life Educators (FLEs) in a state in the Appalachian United States identified behaviors, outcomes, and challenges. FLEs identified four behaviors they believed were essential to their roles. They also identified challenges that were perceived to negatively impact their abilities to meet their reported expectations of being a family life educator. Their behaviors, outcomes, and challenges corresponded to the National Extension Parenting Educators’ Framework. The author used grounded theory methods to analyze the interview data. The FLEs who were interviewed identified their primary identity as the Effective FLE. Challenges interrupted FLEs abilities to be effective, but when FLEs were enacting the effective FLE identity they saw positive outcomes. A primary implication is that when FLEs engage in behaviors deemed essential, positive outcomes for parents and themselves are possible. Challenges, however, interrupt that process in a negative way.

Published: May 2022

The numbers of foreign-born undergraduates in the United States have increased in the 21st century, yet literature exploring their perceptions of and experiences with campus communities and sense of school belonging is limited. This cross-sectional study includes self-report data from 153 foreign born undergraduates. Data were collected during the first year of the Donald J. Trump Presidential administration, a sensitive socio-historical time period for this population. Correlations between students’ sense of school belonging were calculated using variables related to discrimination and rejection, concerns about deportation, access, importance of campus space, social capital, support, and civic engagement. Analysis of variance were calculated to ascertain group differences based on immigrant status. Results indicate that macro-level sociopolitical contexts impact this population negatively, but colleges and universities may support foreign-born undergraduates by creating and maintaining safe campus spaces for peer-to-peer and peer-to-faculty interactions. Civic engagement and preventive education could be critical for promoting success. Family Science and Family Life Education programming may be particularly useful; this is discussed as implications for practice.

O conhecimento científico e suas formas de apropriação social mobilizam o fazer-ser dos sujeitos, conforme a formação imaginária que os constitui. Com isso, descrevemos e interpretamos a forma-conteúdo do termo ‘brilho’, em textos e discursos de rap (rhythm and poetry), por transições de sentido que o formulam, tanto como fenômeno luminoso quanto dizer social. De letras musicais e de audiovisuais de rappers brasileiros, como: o paulista Emicida, a curitibana Karol de Souza e o soteropolitano Baco Exu do Blues, analisamos a produção de sentidos de ‘brilho’, em articulação com o conhecimento científico e outras leituras, indicando possibilidades de discussões interdisciplinares e interculturais para o ensino de ciências. Campo de análise instigante, e em disputa no espaço-tempo escolar, linguagens dissidentes e formações discursivas racializadas desvelam uma urgente função social, na Educação em Ciências: a promoção de equifonias e equipotências étnico-raciais.

The present study focused on the evaluation of the state of riparian ecosystems of the Bumbu River by the riparian strip quality index. The Riparian Quality Index (RQI) is a synthesis of information to assess the health of the riparian ecosystem along its course. Physical and chemical water quality analyses of this hydrosystem showed a slightly acidic pH (6.6 to 6.9), high conductivity (188 to 202µs/cm), a temperature around 26 °C and high turbidity (80 to 91 NTU), low dissolved oxygen (1.49 to 1.89 mg/l), nitrate, phosphates, BOD5 and COD had high average levels of 45.4 mg/l, 14.8 mg/l, 15.6 mg/l and 24.8 mg/l respectively. The examination of the spatial variation of this index according to the different stations shows that the quality of the riparian strips of the Bumbu River is weak to accomplish their ecological functions with an RBQI around 34.6 and 46.3. The herbaceous and cultivated strata occupied important proportions of the riparian strips of this hydrosystem.

Parasitic infections of wild animals can lead to the death of the affected animals tending towards extinction and act as a predisposing factor for the development of secondary infectious diseases. Infected animals serve as source of infection to other wildlife and zoonosis to human. This study was carried out to determine the gastrointestinal parasites of wild animals found within the forests of Zuku and Rumfan Gwamna villages in Bassa LGA. 238 fresh faecal samples were collected from wild animals found within the forests. The samples were each prepared using direct wet mount, sedimentation and floatation techniques, and staining method. From the number examined, 227 (95.38%) samples were positive for GIP infection. Nematodes were the most prevalence (64.84%) with Ascaris lumbricoides being the highest species (46.64%), while trematodes had the least prevalence (11.45%). Age and sex had no significant effect in the parasite’s infection except Trichostrongylus retotaeformis which had significant difference (p<0.05). Among the animals infected, Giant rats was most prevalent (100%) followed by Squirrel had (94.14%), while the Adamawa turtle doves had the lowest infection (89.66 %). The result of this study shows higher prevalence of GIP infection, and presence of various genera in the study area. Hence, more study is necessary to identify the species of parasites in animals within the study area. Deworming of wild animals in the forests with broad spectrum anthelmintic is recommended to prevent zoonotic infections of people living in the communities.

Published: May 2022

The effects of the consumption of formulated (A1, A2 and A3) and commercial (AT) feeds on the zootechnical and nutritional performance of quail (Coturnix japonica) were studied. The experiment involved 80 1-day-old quails. At the end of the experiment which lasted 9 weeks, the quantities of food ingested per day by quail A1, A2, A3 and AT were respectively 25.27±0.02 g, 25.34± 0.08g, 23.83±0.11g and 23.85±0.08g. A3 and AT quails had the highest mass gains with respective values of 3.65±0.22 and 3.64±0.17 g/d. The best feed efficiency after the growth phase was observed with quail fed with growth feed formulated A3 (6.52 ± 0.05). The carcass yields of the quails fed with the formulated growth foods A1, A2, A3 and commercial AT are respectively 63±0.01; 66±0.01; 64±0.03 and 64±0.03%. The highest mortality rate (10%) was found with quails fed A1 and A2 formulated growth feed. In short, among the formulated feeds, feed A3 had a better impact, similar or even greater than that of commercial feed AT on the zootechnical performance of the Japanese quail studied.

Published: May 2022

To authenticate doubts relating to influence of altered state of some ions in insulin resistance and hypertension we analysed some biomolecules; glucose, insulin, glycated hemoglobin, magnesium, zinc, sodium, potassium and copper from diabetics, non-diabetics and hypertensives. Adopting spectroscopic and immunoassay methods values obtained were statistically evaluated by Anova (Analysis of variance). We observed identical pattern in glucose concentration, glycated hemoglobin and insulin levels among hypertensive and non-hypertensive subjects. However, an aggregated insulin response to glucose was elevated significantly (34.5+3.2 vs 20+2.3 µIU/mL, P<0.05). Zinc and magnesium levels were inversely correlated with HbAIc in insulin dependent diabetics and Non-insulin dependent diabetic (P<0.05). We observed Values increasing in tandem relationship with hypertension. We conclude that while hypertension and insulin resistance may have differential biochemical precursor, a nexus could be established for the place of ionic interferences in these disorders.

Authors: Motovilov A. I. , Solovejev I. I.
Published: May 2022

THE PURPOSE. Consideration of issues related to the study of ways to increase the capacity of the electrical network, characterized by the maximum transmitted power between the nodes of the electrical network. Switching in the electrical network and power imbalance in nodes during transmission of electricity are reasons of overloads and blackouts. To prevent overloads, the transmission volumes are reduced. It is the reason for a decrease in the reliability of power supply to consumers, the efficiency of using energy resources and disconnection of systems. In practice, the traditional methods of reducing network congestion are generation regulation, changing the network topology, and, if they are not enough, disconnecting consumers from the power grid.

METHODS. Solving the problem, a computer model was used, created in the RastrWin3. This study transmission capacity of the electrical network with the taking influence equalizing EMF between the nodes of the power grid.

RESULTS. The article describes the relevance problems, it is shown that the regulation of the equalizing EMF allows you to change the value of the maximum allowable power transmitted between the nodes of the electrical network. CONCLUSION. The results of the study can be used in the practice of dispatch control to solve problems of improving the reliability, planning and operating the power system in real time. The efficiency of the proposed algorithm is tested experimentally.

Published: May 2022

THE PURPOSE. To consider the problems that arise when creating a composite heatinsulating material, including a layer of microspherical granules. Numerical modeling of a composite material with different volume content of microspheres and different options for the formation of voids. Determination of the influence of the presence of zones not occupied by microgranules on the insulating properties of the composite material. Determination of the influence of the volume content of microspherical granules on the heat flux through the composite material.

METHODS. Numerical simulation was carried out by creating models of elementary cubic cells of a composite with a package of 27 microspheres in the ANSYS Fluent 19.2 software package. The evaluation of the insulating properties was carried out by measuring the thermal conductivity coefficient.

RESULTS. The article investigates the influence of the presence of zones not occupied by microspherical granules on the thermal insulation properties of a composite material. Models of elementary cubic cells with different volume content of microgranules are constructed. Models of elementary cells are built with various options for the formation of voids, such as the removal of a vertical or horizontal row of granules and the compaction of granules vertically or horizontally.

CONCLUSION. The removal of microgranules has a significant effect on the insulating properties of the composite. The lowest thermal conductivity coefficient was obtained for a simple cubic cell with a volume content of microgranules φ = 40%. The presence of voids in the material contributes to large heat losses, and in the case of a vertical through channel, the heat losses are greater than for a horizontal through channel. In the case of densification of spheres, heat losses in the zone not occupied by microgranules are compensated by a decrease in the heat flux in the area with densification of spheres.

Published: May 2022

Nowadays, in Malaysia, one of the country's challenges is the improper management and disposal of solid waste. The leading sector that generates most of the solid waste in Malaysia is the agricultural sector from oil palm fibre, similar to oil palm trunk fibre, which is also be used as an additive in producing foamed concrete (FC). However, FC presents a weakness in tension, which can be reduced by adding an adequate volume of waste biomass by-product such as oil palm trunk (OPT) fibre. Accordingly, this study was undertaken to investigate the potential of utilising OPT fibre as a reinforcement in FC. There were four different volume fractions of OPT fibre: 0.15%, 0.30%, 0.45%, and 0.60% used as an additive to the FC mix. Two densities, 600 kg/m3 and 1200 kg/m3, were cast and tested. All FC specimens were then prepared and left to cure and exposed to the elements for 7, 28, and 56 days. In this study, to properties were examined: mechanical and durability properties. The results showed that the addition of OPT fibre in FC improved the compressive strength, flexural strength, tensile strength, water absorption, drying shrinkage, porosity and ultrasonic pulse velocity of the FC. OPT's surface roughness was proved beneficial for fibre to matrix interfacial bonding since a coarser surface permit OPT fibre and matrix interlocking in the hardened cement matrix. Based on the results of this study for 600 kg/m3 density, 0.30% volume fraction was the optimum amount added to the FC to achieve the best durability and mechanical properties. While for 1200 kg/m3, 0.45% volume fraction of OPT was the optimum percentage.

Increasing the capacity of structures especially bridges can be done by various methods, one of them is by strengthening. Strengthening using strands has been used in various constructions. However, strengthening in reinforced concrete beams has not been done much because it will have many difficulties in the implementation. The focus of this research is shear strengthening using non-stressing strands. Strand is attached to the beam with epoxy. In certain intervals, strands are also anchored on the vertical side of the beam with U-shaped reinforcing steel. The basis of the research is experimental testing in the laboratory. The test specimens have consisted of a specimen without strengthening (BU-Normal) and 2 specimens with strengthening (BU-SV1 and BU-SV2). Dimensions of specimens are 250mm x 400mm x 1700 mm. In the laboratory, all specimens are loaded by a monotonic static load until collapse conditions. The results of the loading test at yield condition show that BU-SV1 and BU-SV2 can increase shear capacity respectively by 13.735% and 10.300% when compared to beams without strengthening (BU-Normal). Whereas at the collapse condition, BU-SV1 and BU-SV2 can increase shear capacities respectively by 34.886% and 25.360% when compared to beams without strengthening (BU-Normal).

Palm oil boiler ash is a type of industrial waste from palm oil production, which abundantly disposed on landfill, and contaminate the soil and environment. Recently, boiler ash as a by-product is introduced as an additive in chemical stabilization, known as geopolymer. An alkaline solution functions to activate the silica-alumina structure bonding to replace the Ordinary Portland Cement in concrete application but few in soil stabilization study. This study investigates the strength of laterite with a geopolymer. Boiler ash was chosen as source material, with sodium hydroxide and sodium silicate mixed at a ratio of 1:2. Unconfined compressive test (UCT) and SEM were conducted for laterite soil with different geopolymer percentages. The test was conducted by adding a different geopolymer percentage at 0%, 5%,10%,15%, and 20% mixed with laterite soil. The soil sample was cured for seven days for an unconfined compression test (UCT). The result shows that the highest compressive strength was obtained at 15% of geopolymer in laterite soil at 340kPa. SEM tests show that the increased compressive strength was attributable to the 15% of the geopolymer, which had a compact and dense structure and less unreacted raw materials. In conclusion, the results indicated that 15% of geopolymer gives optimum value in enhancing laterite properties' strength. The ﬁndings support boiler ash usage as by-products in geopolymers' production for potential use in soil strength stabilization.

This research aims to examine the sulfate and chloride durability behaviors of geopolymer composites synthesized by the alkali activation of metakaolin (MK), reinforced by boron waste colemanite (C), silica fume (SF), and slag (S). The resultant geopolymer composites were subjected to magnesium sulfate (MgSO4) solution (concentration 10%), sodium sulfate (Na2SO4) solution (concentration 10%), and sodium chloride (NaCl) solution (concentration 10%) for up to 12 months. The compressive and flexural strengths, microstructure (X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM)), weight changes, and visual inspection of the geopolymer composites were investigated to evaluate their durability behavior. The conclusion proved that the mix of a metakaolin with the addition of 10% C, and 20% SF shows the highest compressive strength for the studied range of mixture design. In geopolymer mortar samples, compressive strength increase was observed due to sodium chloride and sodium and magnesium sulfate effects after three months, while a decrease was observed after six months. These fluctuations were due to the diffusion of solutions in the matrix, formed during the transition of alkali ions from the samples to the solution. The loss of strength after three months could be due to the presence of microcracks, as a consequence of ettringite and gypsum creation in the pores, as well as the transition of alkalis from the sample matrix to the solution.

Byzantine and Georgian Hymnographical Heritage (“Lenten Triodion” under George the Athonite’s Redaction)
Authors: Khachidze Lela

Most of the numerous translations of the great ecclesiastical figure - George the Athonite were created in Greece, on Mount Athos. The “Lenten Triodion” is one of the collections compiled by George the Athonite (1009-1065). He was thoroughly acquainted with the Byzantine and Georgian theological writings. The main principle of his epochal activity was maximum approach of the earlier Georgian translations to the Greek originals. In collections translated from Greek, he tried to show the modern Byzantine liturgical practice in full. The same principle is used in “Lenten Triodion” under his redaction. This is one of the most important liturgical–hymnographic books in Christian church, containing numerous hymns for Great Lent. “Lenten Triodion” under George the Athonite’s redaction is much more extensive than its contemporary Greek analogues. The significance of this collection for the study of Byzantine hymnography is determined by the work done by George the Athonite for identification of the authors of the hymns preserved in it. This collection preserves translations of the hymns of 14 Byzantine poet-melodists of the 5th - 10th centuries. Most of them are well known in scholarly literature, but a significant part of the hymns of the same authors whose originals are not present in the famous scholarly literature are preserved in this collection. The academic edition of this collection according to the nine ancient Georgian manuscripts is prepared by the group of Georgian scholars and its electronic version will be placed on the Internet. Keywords: Byzantine hymnography, George the Athonite, Lenten Triodion, Georgian hymnography
