A Human-Centered Approach to Assessment
Authors: Moloney Kara , Jankowski Natasha A.
Published: February 2025

Much of the focus of the vast body of literature on assessing student learning is on how to assess and implement reporting processes on learning, whether at the classroom, cocurricular, program, general education, or institution level. Yet what is often not acknowledged within the literature or considered in the various recommendations for implementing new or revised approaches for how to assess student learning are considerations of the who—the individual people engaged in assessment. While there has been movement recently toward humanizing the work of assessment by elevating the individuals and people involved in the process of assessing student learning, this article argues that in order to cultivate and sustain meaningful engagement of people in assessment, assessment professionals need to take up a new line of inquiry: themselves. As individuals engaged in change processes, assessment staff can benefit from examination of their identity development as assessment professionals and that identity tempers their interactions with others. Implications for culture(s) of inquiry and the practice of assessment are presented at the end.
Moving Beyond the Gender Binary in Higher Education Data: Institutional Research Leader Perspectives
Authors: Long Kelly
Published: February 2025

Institutional research (IR) leaders play a major role in collecting data on socially constructed identity variables and presenting summary information to senior administrative leaders in higher education institutions. The way IR leaders view and talk about gender data has the potential to influence how institution leaders view gender-related issues. This qualitative study examined IR leader interpretations of gender data and considered the extent to which their responses reflected an established social justice framework (QuantCrit). The results showed that some IR leaders have concerns about binary gender variables, but more information may be needed on how this variable relates to gender discrimination.
Nonparametric Analysis in Educational Test Development: A Mokken Scale Approach to Evaluating EFL Vocabulary Proficiency
Authors: Jahanaray Ali , Faravani Akram
Published: February 2025

Mokken Scale Analysis (MSA) can offer a more flexible approach to common Item Response Theories (IRT) as a non-parametric method for evaluating educational tests with ordinal data. This study applied MSA on a Vocabulary Levels Test (VLT) originally developed with IRT methods among 234 English as a Foreign Language (EFL) students to test the assumptions of MSA, including unidimensionality, monotonicity, local independence, and invariant item ordering (IIO) with mokken package in R. MSA assumptions successfully met with the VLT validated with validating the VLT being a unidimensional test with Automated Item Selection Procedures (AISP) and Genetic Algorithm (GA) methods utilized. Scalability coefficients indicated a medium scale, and monotonicity was upheld, which ensured consistent participant rankings. IIO showed that item difficulty remained consistent across respondents. MSA highlights its potential for exploratory analysis, particularly with smaller sample sizes and ordinal data, offering a less restrictive alternative to parametric IRT methods.

Primary school is the education level where academic life begins. The years when the foundations of the future educational life were laid coincide with this period. Thanks to pre-school education, the child develops his autonomy by separating from his family and adopts some basic habits and rules, and will easily adapt to school. It provides a smooth transition for the child to the lesson- and success-oriented education system of primary school. Preliminary learning provided through achievements and activities facilitates the child's success in primary education and provides opportunities for reinforced behavior and learning. Pre-learning has a great impact on children being happy and successful in this environment. The method in the quantitative approach contains a description of the identification of variables; population, sample, and sampling techniques; data collection methods and tools; instrument validation; and data analysis methods. The purpose of this study is about whether pre-school education is effective on first grade students. The purpose of this research is to reveal that there are differences between students who receive pre-school education and those who do not, and to show that students start primary education more prepared and are successful.
Leadership Styles, Quality of Education, and Educational Institution Management: A Systematic Review in the Perspective of Sustainable Education
Authors: Sugiyanto Heri
Published: February 2025

This study aims to uncover the relationship between leadership styles, quality of education, and the management of educational institutions within the context of sustainable education. A systematic literature review of research published between 2014 and 2024 reveals that transformational leadership plays a significant role in enhancing educators' motivation, organisational culture, and creating a conducive learning environment. The quality of education is influenced by the integration of technology, educators' competencies, and innovative teaching approaches. The use of technologies such as augmented reality and online learning platforms significantly improves learning effectiveness; however, challenges such as access inequality in rural areas remain critical issues. Furthermore, data-driven management has been proven to enhance resource efficiency and support informed decision-making. This study concludes that the integration of leadership styles, education quality, and sustainability-based management is essential to achieving adaptive, inclusive, and innovative education. These findings provide practical contributions in designing sustainable education strategies and supporting the achievement of the Sustainable Development Goals (SDGs). With a comprehensive approach, this research offers both theoretical and practical insights for educational institution leaders in addressing the challenges of globalisation and digitalisation.

Este artigo tem como proposta, analisar as políticas públicas federais e estaduais voltadas para a prevenção e contenção do bullying e cyberbullying no Brasil, após a promulgação da Lei nº 13.185/2015. A lei em questão institui o Programa de Combate à Intimidação Sistemática (bullying) em território nacional. A metodologia utilizada foi a análise documental realizada no período de 2019/2021, com base em iniciativas do Ministério da Educação e de oito estados brasileiros que participaram da pesquisa através de contato via e-mails. Foram elencadas como categorias de análise dos projetos recebidos: ações de diagnose, prevenção, combate e avaliação, seguindo as orientações propostas na legislação mencionada. A pesquisa revelou que, embora a Lei tenha promovido o reconhecimento do bullying como uma questão de relevância nacional que afeta muitas pessoas no Brasil e no mundo, a implementação da lei ainda é insuficiente e possui muitas lacunas. Muitas Secretarias Estaduais de Educação não possuem programas estruturados específicos para ações antibullying ou para a promoção de convivência ética. Este artigo traz como proposta ações sistemáticas e não pontuais, pautadas em referenciais científicos, com base em uma educação integral preocupada com o desenvolvimento de valores morais, na construção de uma convivência ética e democrática, que estimule a relação dialógica entre todos os membros da escola, favorecendo o protagonismo dos estudantes e a capacitação de docentes e de todos os membros escolares. Também se faz necessária a incorporação de mecanismos de denúncia de fácil acesso e a formação de uma rede sólida de apoio que possa acolher tanto os alvos como quem pratica o bullying.

Authors: Proença Barbara , Maia Valéria Cid
Published: February 2025

Rio de Janeiro is one of the most studied Brazilian states for insect galls. Still, several municipalities lack or have few gall records. This is the case of Armação dos Búzios and Rio das Ostras. Our objective was to provide new records of insect galls, contributing to the knowledge of their richness and geographic distribution in the state of Rio de Janeiro, and consequently in Brazil. We investigated the restinga vegetation along the access road to José Gonçalves Beach in Armação dos Búzios and the vegetation of the Mirante da Baleia in Rio das Ostras during two hours in each area and photographed the host plants and galls. We identified this material and verified new records. Seven gall morphotypes are reported for the first time in the study areas. They occurred on five botanical species of five families. Guapira opposita (Vell.) Reitz. (Nyctaginaceae) was the only multi-host plant. Cecidomyiidae (Diptera) and Hemiptera were the gall-inducing taxa. Most galls were green, glabrous and occurred on leaves. We reported for the first time Bruggmannia elongata Maia & Couri, 1992 and Proasphondyia guapirae Maia, 1994 in Armação dos Búzios.

Parkinson's disease (PD), a progressive neurodegenerative disorder, is marked by dopaminergic neuronal loss in the substantia nigra and the pathological accumulation of alpha-synuclein. Current treatments primarily address symptoms without halting disease progression, underscoring the need for novel therapeutic strategies. This study investigated the effects of co-administration of luteolin and curcumin in a transgenic Drosophila melanogaster model of PD. Luteolin and curcumin, recognized for their antioxidant and anti-inflammatory properties, were administered to evaluate their impact on survival rates, locomotory activity, muscular integrity, and oxidative stress markers. Results demonstrated that the treated group exhibited a significant increase in survival rate and improved locomotory and exploratory activities compared to untreated mutants. The larva crawling assay revealed enhanced muscular integrity, suggesting the restoration of motor function. Biochemical assays indicated reduced malondialdehyde (MDA) levels and increased catalase and thiol activity in the treated group, highlighting the compounds' ability to mitigate oxidative stress. Molecular docking analyses revealed strong interactions between luteolin, curcumin, and key PD-related proteins, including PERK, AChE, and MAPK10, with high binding affinities and favorable binding free energy values. These findings suggest that luteolin and curcumin target pathways implicated in oxidative stress, neuroinflammation, and protein misfolding, offering a multi-targeted approach to PD therapy. This study underscores the therapeutic potential of luteolin and curcumin as complementary agents in managing Parkinson’s disease, paving the way for further exploration into their clinical applicability.

The high failure rate of welded structures has made it necessary to investigate some welding parameters that may be involved in these failures, such as groove angles, quenchants, welding current, welding voltage, and weld pass speed. This investigation aimed to investigate the impact of quenchants and groove angle on the structural integrity of a Single-V butt welded joint, using AISI 1024 steel. Nine samples, each measuring 150 x 80 mm, were cut from an 8 mm thick AISI 1024 steel plate. The findings of the study showed that, in comparison to oil and kerosene-quenched samples, the weldments cooled with natural air had significantly greater impact strength for the corresponding groove angles of 30°-130J, 45°-128J, and 60°-122J. Furthermore, out of all the groove angles taken into consideration in this study, the weldments of the samples that were cooled naturally had the highest hardness value; the maximum value of 188HBW was obtained with a groove angle of 60°. At groove angles of 45° and 60°, respectively, Mobil oil quenchant produced greater hardness values of 150HBW and 159HBW than kerosene, but at a groove angle of 30°, kerosene produced a larger hardness value of 152HBW than Mobil oil Although the observed mechanical qualities varied across all samples due to the changes in the quantities of cementite and pearlite present in the samples, the microstructural inspection studies showed phases of cementite and pearlite structures on all samples. The study's conclusions will help structural industries achieve the best possible weldment performance for AISI 1024 carbon steel

Twenty-two different brands of vegetable oils were collected in different markets in Ekiti/Ondo State of Western Nigeria and tagged as samples A to V, respectively. The oils were estimated for retinol and various antioxidants like; phenol, tocopherol, ascorbic acid and iron reducers using standard methods. The study showed no significant (p>0.05) difference in the concentrations of the retinal, tocopherol and ascorbic acid present in the different oil brands but with significance (p<0.05) differences in the concentration of tannic acid and reducing properties of the oils. For instance, the Sample B, F and N had the highest (857.8 USP/g) while sample I had the lowest (816.6 USP/g) concentrations of retinol, respectively. However, the level of added retinols and other antioxidants were within the limits approved by the laws and controls of the Regulatory bodies (NAFDAC and SON) for the imported but edible vegetable oils. The report of this present analytic survey showed the degree of compliance stipulated by the regulatory bodies by the importers and local producers, (in the areas of the added retinol and antioxidant concentrations) in these imported vegetable oils ranges.
Rethinking Rural Schooling in Laos
Authors: Huijsmans Roy
Published: February 2025

By combining insights from mobilities studies and the anthropology of the state and development, conceptual space is created for thinking about the social effects of the diverse sets of mobilities underpinning and related to rural schooling. This includes realising the state as a social relationship. Thereby, this article goes beyond a common deficit perspective on rural schooling. Drawing on ethnographic data, I show how diverse mobilities involving different sets of actors are valued and recognised differently, in part, because of their particular relation to constructs of remoteness, the state, and visions about rural futures.

Among many causes of weed growth and rice’s low yield, improper nitrogen management are thought to be an important issue. An experiment was conducted from December 2021 to June 2022 at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh. Five different nitrogen management and six different weed control techniques were applied to BRRI dhan29. Four of the thirteen weed species were grasses, three were broadleaf, four were sedges and two were aquatic. N1W0 (100% N from urea × un-weeded control) had the greatest weed density and dry weight (78.67 m-2 and 4.80 g m-2) at 20 DAT, whereas 100% N from USG × weed free over the time (N4W1) treatment had the lowest weed density and dry weight (0.00 m-2 and 0.00 g m-2). When 100% N from USG was applied coupled with weed-free conditions the maximum numbers of effective tillers hill-1, grains panicle-1, straw yield, and biological yield were 10.11, 122, 6.23 t ha-1, and 11.07 t ha-1, respectively. The minimum effective tillers hill-1, grains panicle-1, straw yield and, biological yield was 6, 70.84, 3.13 t ha-1 and, 4.95 t ha-1, respectively found at 0 kg ‘N’ ha-1 followed by un-weeded control. The maximum grain yield was 5.84 t ha-1 for 100% "N" from USG and weed-free conditions, while the lowest grain yield was 2.15 t ha-1 for 0 kg "N" ha-1 and un-weeded control. However, because of the labor problem and the weeds' tremendous capacity for regeneration, it is impossible to keep the field weed-free over the whole growing season. This study showed that farmers may choose to apply 100% N from USG in combination with either pre-emergence herbicide and hand weeding at 30 DAT or early post-emergence herbicide and hand weeding at 30 DAT to effectively manage weeds and maximize grain yield in boro rice.

Abstract
Background and Aim: The camel is an important livestock in the semi-arid, arid and desert regions. The study was carried out to determine the level of bacterial contamination and factors associated with total bacterial count and coliform contamination along the camel milk chain in Isiolo County, Kenya.
Materials and Methods: A cross-sectional study was carried out between February and March 2024 and milk samples were collected along the milk value chain. Milk samples were collected from farmers, transporters, milk bulkers, and retailers. The samples were assessed for total viable bacterial counts (TVBC) and total coliform counts (TCC), on the plate count agar and violet lactose bile agar.
Results: A total of 191 samples were collected, 42.93% from producers, 24.08% from traders, 19.9% from bulkers, and 13.09% from transporters. Total Viable Count (TVC) showed that 34.55% of samples had moderate contamination (between 10³ CFU/ml and 10⁵ CFU/ml), while 23.04% exhibited severe contamination levels (above 10⁶ CFU/ml). For Violet Red Bile Agar (VRBA) testing, 46.60% of the samples exceeded the threshold of 1000 CFU/ml of milk, indicating significant bacterial contamination, while 29.84% showed no bacterial growth. Logistic regression identified factors associated with increased contamination as female respondents, urban location, and use of disinfectants.
Conclusion: The study showed that there was moderate to heavy bacterial milk contamination on about 50% of the milk samples tested along the camel milk value chain.
Key words: Camel, milk, total viable bacterial counts, total coliform counts, value chain, hygiene practices, contamination risk factors, Kenya

The presence of phytate in animals’ feeds restricts the availability of phosphorus and other nutrients for monogastric animals. This research is aimed to optimize the fermentation parameters for enhancement of phytase production by Bacillus sp. (in: firmicutes) strain MJ. Bacteria isolates from poultry farm house were screened for phytase production on phytase screening medium (PSM). The optimization of fermentation parameters was assessed by central composite design (CCD), while the interaction of carbon, nitrogen, pH and inoculums size were studied by response surface methodology (RSM). One isolate identified as Bacillus sp. (in: firmicutes) strain MJ (OR852745) produced the highest clear zone (7 mm). The model predicted optimum phytase production at 6.97 U/mL using 2.72 g of carbon, 1.5 g of nitrogen 0.3 mL of inoculums at pH 6.9 closed to the experimental optimal phytase of 7.27 U/mL. This condition yielded 1.29-fold increase over the unoptimized medium. The present study suggested that the phytase from Bacillus sp. (in: firmicutes) strain MJ may have a wide industrial application.

Groundnut decorticators are vital agricultural tools designed to separate kernels from their shells, enhancing efficiency in processing groundnuts (peanuts). Groundnut processing involves several steps, including decortication, which is the removal of the seed coat from the kernel. Groundnut decorticators are machines designed to automate this process, reducing labour requirements and increasing efficiency. This study evaluates the performance of a developed motorized operated groundnut decorticating machine. The decorticator comprises a hopper to feed in the seeds, a rotating spiked tooth drum and a blower powered by 1 HP electric motor, tripping is done by holding the seed over the spiked cylinder. The stripped kernels fall below and are collected separately. Blower is incorporated into the machine to separate lighter seeds and chaff from the groundnut kernel. The components were designed, fabricated and assembled accordingly. Experimental runs were conducted to evaluate the performance of the machine. The quantity of groundnut seeds fed into the machine ranges from 0.20 kg to 0.75 kg and time taken to decorticate the seeds increases with the quantity of seeds, ranging from 20 seconds to 42 seconds. The weight of decorticated kernels obtained also increases with the quantity of seeds, ranging from 0.170 kg to 0.71 kg. The decorticator has a throughput of 54kg/hr. and decorticating efficiency of 91% with breakage percentage of 3.56. It can be concluded that the machine is functional and can be used for various industrial and domestic applications.

Syftet med denna studie var att undersöka vilka ligninkomponenter som påverkar fibersmältbarheten hos gräs. Fibersmältbarhet analyserades som neutral detergent fiber digestibility med near infrared spektroskopi på förstaskörd av gräs av arterna ängssvingel (Festuca pratensis), rörsvingel (Festuca arundinacea), engelskt rajgräs (Lolium perenne L.), hundäxing (Dactylis glomerata) och timotej (Phleum pratense L. Totalt skördades 14 olika sorter vid två utvecklingsstadier och under två år.

Ligninkomponenterna guaiacyl, syringyl och p-hydroxyfenyl analyserades med pyrolysgaskromografi/masspektroskopi. Lignin analyserades också som acetylbromidlösligt lignin (ABSL) och med nära-infraröd spektroskopi. Hydroxykanelsyrorma kumarsyra och ferulinsyra analyserades med pyrolys gaskromografi/masspektroskopi efter att tetrametylammoniumhydroxid tillsatts.

Syringyl var den ligninkomponent som hade starkast korrelation med fibersmältbarheten. Korrelationen var negativ och starkare ju längre tid som fibersmältbarheten mättes.

Innehållet av hydroxykanelsyror var negativt korrelerat med fibersmältbarheten, när den mättes under kort tid (30 timmar). Fibersmältbarheten påverkades inte av innehållet av hydroxykanelsyror när den mättes under längre tid (120 respektive 240 timmar).
