Individualisiertes Lernen mit digitalen Bildungsressourcen
Authors: Pietrusky Stefan , Kalz Marco 
Published: February 2025

Ziel dieser Studie ist die Entwicklung eines Konzepts für die einheitliche Gestaltung digitaler Bildungsressourcen anhand verbindlicher Kriterien zur Förderung individualisierten Lernens im Unterricht. Während die aktuelle Literatur viel Wert auf OER legt, wird die Anpassungsfähigkeit digitaler Bildungsressourcen unabhängig von Lizenzfragen weniger diskutiert. Zudem fehlen Daten zur höheren Wirksamkeit von OER im Vergleich zu kommerziellen Bildungsressourcen. Daher wurde auf der Basis pädagogischer und lernpsychologischer Theorien ein theoretisches Konzept mit verbindlichen Kriterien für digitale Bildungsressourcen (DER) aus Lehrerperspektive entwickelt. Eine Delphi-Studie mit Lehramtsstudent:innen und Lehrenden identifizierte in der ersten Runde (N = 69) 19 wichtige Kriterien. In der zweiten Runde (N = 88) wurde die Wichtigkeit der Kriterien beurteilt und dabei festgestellt, dass eine höhere Häufigkeit eines Kriteriums (erste Runde) mit einer hohen durchschnittlichen Zustimmung (zweite Runde) korrelierte, was auf eine starke Zustimmung hinweist. Die drei wichtigsten Kriterien für DER sind Benutzerfreundlichkeit, Adaptierbarkeit und Verständlichkeit. Die kostenlose Verfügbarkeit von digitalen Bildungsressourcen wurde im Vergleich zu anderen Bewertungskriterien als weit weniger bedeutsam eingestuft. Die Ergebnisse der Delphi-Studie zeigen die Notwendigkeit alternativer Konzepte mit eindeutigen Kriterien zur Entwicklung digitaler Bildungsressourcen, die individualisiertes Lernen aus Sicht von Lehrer:innen fördern.

In the context of climate change, it is of utmost importance to study the transformation of carbohydrate-acid and phenolic complexes of grapes as they reach technical and phenolic ripeness, the discrepancy between which is increasing against the background of climate change. Studies in this direction are relevant, and in future they will open the way to predict the response of a grape plant to abiotic environmental factors, the formation of quality indicators of raw materials and finished products. The studies conducted allowed revealing the effect of various factors on the formation of phenolic complex of red grapes. It was shown that the total anthocyanin potential in the studied grape samples varied from 735 to 1976 mg/dm3 and was characterized as average → excellent. The dependence of the percentage of extracted anthocyanins on the mass concentration of sugars in grapes, expressed by a cuspidal function, was established. The maximum degree of anthocyanin extractability was observed at grape sugar content of 19–23 g/100 cm3, and amounted to 53–65%. The positive effect of the cold night index on the total anthocyanin potential of grapes was confirmed (r = –0.58). At the same time, a direct dependence (r = 0.75) was observed between the degree of anthocyanin extraction from grapes and the cold night index. The authors established a decrease in the content of phenolic substances in must after pressing whole berries as the value of the glucoacidimetric indicator increased (r = –0.70), as well as a decrease in the mass concentration of phenolic substances after 4 hours of infusion (r = –0.59). From 82.7 to 96.3% of all phenolic substances in grapes were represented by flavan3-ols and anthocyanins. The predominant anthocyanins in grapes were malvidin3-Oglucoside and malvidin3-Ocoumaroylglucoside. The mass concentration of malvidin3-Oglucoside ranged from 580 to 1224 mg/kg or 47.4–81.3% of all grape anthocyanins. The proportion of malvidin3-Ocoumaroylglucoside amounted to 9.3–23.8% of anthocyanin complex components.

Improving groundwater treatment decisions using Giardia and total aerobic spores to assess surface water influence
Authors: Berger Philip , Crosby Jake , Wallis Peter , Hain Ethan , Hutchinson Marcella 
Published: February 2025

ABSTRACT

Giardia and Cryptosporidium detection in public water supply (PWS) ground water is rare. PWSs are identified as ground water under the direct influence of surface water (GWUDI) using microscopic particulate analysis (MPA) to determine GWUDI. A Canadian dataset of 1,221 samples from 590 ground water devices was collected during the years 2006–2020. Samples were analyzed using the suggested MPA method (for diatoms), for total aerobic spore (TAS), and for parasitic protozoa (EPA Method 1623) (727 samples using the EPA MPA-suggested method, 494 samples using US EPA Method 1623). Giardia cysts were found in 21 samples collected from 16 drinking water production devices. Cryptosporidium oocysts were found in three devices, co-occurring with Giardia. These detections in routine PWS samples using US EPA Method 1623 are the most robust reported detections worldwide. A generalized linear model was used to determine the co-occurrence of TAS or diatom with Giardia and demonstrated that diatoms supplemented by TAS were better than diatoms alone. Diatoms and TAS have complementary parameter sensitivity and specificity when analyzed by sample and by device, i.e. sensitivity (by sample): TAS 78%; diatoms 24% and specificity (by device): TAS 39%; diatoms 87%.

Published: February 2025

ABSTRACT

The rainfall series exhibits uncertainty and non-stationarity. Improving the accuracy of rainfall prediction is of significant importance for flood prevention and mitigation. This study proposes a hybrid model and applies it to rainfall forecasting in the eastern region of Hubei Province. The proposed method first uses variational mode decomposition and improved complete ensemble empirical mode decomposition with adaptive noise to reduce high-frequency noise components. Then, particle swarm optimization and support vector machine are used for training and forecasting. Compared with other models, the prediction model after noise reduction shows better performance than the model without secondary decomposition, with results that are closer to the actual values. The proposed hybrid model outperforms other models, with the predicted trend more closely aligning with the actual data, and the value of R² of predictions for individual cities reaches 0.96. This study not only provides an efficient method for rainfall forecasting but also holds significant importance for understanding and addressing climate change.
Exploring the role of inter-municipal cooperation for promoting water circular economy: Insights from a Southern European country
Authors: Riazi Fayaz , Fidélis Teresa , Teles Filipe 
Published: February 2025

ABSTRACT

This article analyses the role of inter-municipal cooperation (IMC) as a governance model in promoting water circular economy (WCE) and water reuse practices. Despite the potential benefits offered by IMC, little is known about how could contribute to fostering WCE adoption. The article develops and uses a framework to assess the role of IMC in advancing WCE strategies, addressing three key dimensions: involvement of IMC in advancing WCE, robust governance for WCE, and territorial fit and spatial concerns. It uses Portugal as a case study within the South European Union, where water scarcity and interest in IMC approaches are growing. Considering the emphasis on collaboration in legal and legislative frameworks, the results show the constrained role of inter-municipal communities in promoting the WCE through water reuse in Portugal. In addition, the limited integration of water reuse into territorial strategies highlights the lack of integration of water management and spatial planning. Moreover, the robustness of governance is hindered by a lack of funding, inadequate infrastructure, spatial barriers, a lack of experts or knowledge, and a deficiency in common goals or diversity of interests. Further research is essential to address territorial fit and spatial considerations critical to WCE adoption.

ABSTRACT

Naphthenic acids are the most significant environmental pollutants created by the extraction of oil from oil sand deposits. Since the diffusion coefficient of naphthenic acid has a direct effect on the modeling of diffusion and advection and determining its behavior and movement in water, this number is needed for modeling work and future studies. In this study, the diffusion coefficient of this substance in water was determined experimentally and in a laboratory. The researchers used the device of the Armfield company, known as the device for determining the diffusion coefficient in liquids. In this research, after examining different methods of determining the concentration of naphthenic acid in the water, including UV–vis, chemical oxygen demand (COD), crystal violet, oxidation reduction potential, pH meter, and electrical conductivity meter, the COD method was the best method in determining the concentration at different times, which provided a suitable numerical range for the concentrations and a device was built for heavy oil pollutants with poor solubility in water to specify the diffusion coefficient, and for the first time, the diffusion coefficient of naphthenic acid in water was obtained with experiments and experimental equations as 0.69 × 10−9 m2/s which indicates the weak diffusion of this substance in water.

Introduction. In the police profession, illegitimate tasks have detrimental impacts on personal and organizational wellbeing. It affects job performance, job satisfaction level and relationship between law enforcement agencies and the communities they serve. There is no valid questionnaire to measure illegitimate police task stress. The objective of this study was to develop and evaluate the psychometric features of illegitimate police tasks stress questionnaire (IPTSQ). Methods. The present study employed a mixed-methods approach, integrating both qualitative and quantitative methods to explore illegitimate tasks among police officials (N=620) in Pakistan. We conducted exploratory factor analysis on 160 employees and later cross validated on best factor structure identified by way of confirmatory factor analysis on 460 police officials. Results. The result showed that the illegitimate police tasks stress questionnaire was composed of 21 items with 2 factors (unnecessary tasks and unreasonable tasks). The composite reliability of IPTSQ was 0.89. Discussion. In conclusion, it is valid, reliable and easy to use scale. The psychometric properties of this scale are satisfactory, making it well-suited for research purposes, policies, or decision makers in police department. This scale would help the police department evaluate and prioritize tasks in a way that is consistent with their fundamental goal of maintaining public safety and enforcing the law.

Published: February 2025

Este artículo presenta algunos hallazgos de la Encuesta Nacional de Consumos Culturales (ENCC) realizada en 2022 en Argentina. Se reconstruyen los antecedentes de estudios de consumos culturales en América Latina para describir luego el diseño metodológico y las dimensiones que aborda la encuesta, así como los desafíos de realizar esta medición apenas concluida la pandemia de COVID-19. Se hace foco en los resultados sobre consumo de televisión y plataformas de streaming, uso de redes sociales y lectura de noticias. Los datos de la ENCC muestran que la televisión sigue siendo relevante, aunque el streaming y las redes han expandido sus audiencias. El noticiero sigue teniendo un rol importante en los consumos de información, pero se evidencia un creciente uso de las redes sociales para informarse. Se observa como novedad la simultaneidad e integración de diferentes tipos de prácticas, por ejemplo, el uso de redes sociales para comentar lo que se está viendo en televisión o en plataformas. Se concluye resaltando la importancia de los datos de la ENCC para la investigación y formulación de políticas públicas orientadas a mejorar el acceso y la participación ciudadana.

INTRODUCTION: Soft tissue tumors are a diverse group of growths that can occur anywhere in the body. While sarcoma only account for about 1% of all malignant neoplasms, they come in many different types and often recur after treatment. This makes accurate diagnosis and monitoring of these tumors and postoperative scars essential.OBJECTIVE: To analyze scientific works of the latest 5 years, which examined medical imaging techniques, specifically multiparametric ultrasound and MRI, and assess their effectiveness in diagnosing soft tissue tumors, including sarcomas and their recurrences.MATERIALS AND METHODS: Search queries were performed in the Google Scholar, PubMed and Web of Science databases and were based on the keywords: «sarcoma of soft tissue», «soft tissue tumor», «soft tissue Ultrasound», «soft tissue MRI», «soft tissue CEUS».RESULTS: The literature analysis determined that multiparametric contrast-enhanced ultrasound is more effective in diagnosing soft tissue tumors than studies without contrast and can be comparable in accuracy to magnetic resonance imaging. However, the accuracy rates reported in publications on this topic were significantly influenced by factors such as the criteria used to select patients, the design of the studies, and the size of the samples.DISCUSSION: This review shows that developing an optimal diagnostic algorithm for soft tissue tumor requires a comprehensive approach considering both the strengths and weaknesses of individual methods and the potential of cost-effective new technologies to improve diagnostic quality.CONCLUSION: Additional research needs to investigate all modes of multiparametric ultrasound and magnetic resonance imaging, as well as the role of echo contrast both in a diagnostic algorithm for detecting soft tissue tumors and in monitoring after surgical resection for sarcomas.
Om lesepraksiser i den norske barnehagen

Published: February 2025

Målet med denne studien er å få innsikt i lesepraksiser i norske barnehager slik de kommer til uttrykk i en nasjonal spørreundersøkelse og fem semistrukturerte fokusgruppeintervju med barnehagelærere. I studien forstår vi lesepraksiser som sosiale, og de beskrives i form av interaksjoner mellom individer og deres omgivelser. Studien har fire fokusområder: initiativ til lesing, gruppeinndeling, avsatt tid til lesing og lesested. Sentrale funn er at: (1) Lesing i barnehagen som regel er spontan og barneinitiert. (2) Gruppeinndeling med planlagt og organisert lesing synes å være vanligere på storbarns- enn på småbarnsavdeling. (3) Det er mindre avsatt tid til lesing i form av faste tidspunkt med de yngste enn med de eldste barna. Og at (4) tilgang til eller mangel på gode lesesteder og bøker påvirker barnehagenes lesepraksiser i vesentlig grad. Basert på resultatene konkluderes det med at den vanligste lesepraksisen i norske barnehager er spontan, barneinitiert og i liten grad planlagt, noe som peker mot et behov for å revitalisere prioriteringen av lesing sammen med barnehagebarn.
ENGLISH ABSTRACT
On Reading Practices in Early Childhood Education and Care Institutions in Norway
The aim of this study is to gain insight into reading practices in Early Childhood Education and Care (ECEC) institutions in Norway as expressed in a national survey and five semi-structured focus group interviews with early childhood teachers. In this study, we understand reading practices as social, and they are described in terms of interactions between individuals and their surroundings (Barton, 2006, p. 29). The study has four focus areas: initiative to read, group division, time set aside for reading and reading spaces. Key findings are that: (1) Reading in ECEC is usually spontaneous and child initiated. (2) Division into groups with planned and organized reading seems to be more common for the oldest than for the youngest children. (3) There is less time set aside for reading in the form of fixed times with the youngest than with the oldest children. And that (4) access to or lack of good reading spaces and books significantly affects the reading practices in ECEC. Based on the results, it is concluded that the most common reading practice in Norwegian ECEC is spontaneous, child initiated and to a small extent planned, which points to a need to revitalize the prioritization of reading together with children.
Mellom skrifta og barnet – tre barnehagelærarar sine strategiar i høgtlesing av bildebøker med få ord og med fleire ord
Authors: Vadstein Anne Marta Vinsrygg 
Published: February 2025

Denne studien går ut på å utforske korleis skriftmengde påverkar tre barnehagelærarar sine val av bildebok, og kva strategiar dei tek i bruk når dei realiserer bildebøker med få ord og med fleire ord for fireåringar i barnehagen. Det empiriske materialet i studien er todelt: (1) Tre barnehagelærarar har filma to lesestunder kvar – ei bok med få ord og ei bok med fleire ord, og (2) deretter har eg gjennomført videostøtta samtalar med barnehagehagelærarane der dei reflekterer rundt førebuing og gjennomføring av lesestundene. Videoopptaka frå høgtlesingane er transkriberte og analyserte komparativt med den skrivne teksten i bøkene, og tematisk, etter kva strategiar barnehagelærarane brukar i realiseringa av verbalteksten. Tre hovudkategoriar er identifiserte: (a) invitasjonar til samtale, (b) innhaldsformidling og (c) språklege tilpassingar. Lydopptaka frå den videostøtta samtalen med barnehagelærarane i etterkant er tematisk analyserte (Braun & Clarke, 2006). Studien viser at barnehagelærarane nyttar fleire strategiar for å byggje bru mellom verbalteksten og barna når dei les bildebøker med få ord, enn når dei les bildebøker med fleire ord. Funna gir innsikt i kva rolle skriftmengde spelar for barnehagelærarar sine bokval og strategiar dei brukar i realiseringa av verbalteksten.
ENGLISH ABSTRACT
Between the Verbal Text and the Child – Three ECEC Teachers’ Strategies Mediating Picture Books With Shorter or Longer Verbal Text
This study explores how text volume impacts three early childhood teachers’ picture book selection and their strategies for mediating books with fewer words or more words for four-year-olds. The research utilizes two forms of empirical material: (1) Three ECEC teachers have filmed two reading sessions each – one of a book with fewer words and one book with more words, and (2) video-supported conversations with the teachers, offering reflections on the reading sessions. The data from the readings was transcribed and comparatively analyzed with the book’s written text, and thematically categorized (Braun & Clarke, 2006) based on the mediation strategies utilized. The audio from the conversations was transcribed and included in the analyses. Three main strategies have been identified: (a) conversational initiations, (b) content dissemination, and (c) linguistic adaptions. The study shows that the three teachers use strategies more frequently to build bridges between the written text and the children when reading books with fewer words. The findings provide insight into the role the amount of text plays in early childhood teachers’ picture book selection and their strategies for mediating written text.
