Published: January 2024

AbstractA smart learning environment (SLE) encompasses the use of advanced technology and smart pedagogical teaching skills tailored to suit students with diverse learning needs. In recent years, some countries, such as the United Arab Emirates (UAE), have formulated policies to implement SLE in their education systems. Since students are the intended beneficiaries of SLE policy, it is crucial to explore their perceptions of its implementation in a novel context. Therefore, this study explored the attitudes of students towards the implementation of SLE in the UAE. To conduct this investigation, 1857 secondary school students (grades 7 and 12) were recruited nationwide. A newly developed instrument was employed to collect data, which were then subjected to exploratory and confirmatory factor analyses to understand its dimensions and validate the factor structure, respectively. Subsequently, the mean scores were calculated and multivariate variance analysis, structural equation modelling, and moderation analysis were conducted to test three specific hypotheses. The results identified ambivalence among students regarding the implementation of SLE and significant differences between them based on their school location and study grade. Additionally, this study discussed the need for nationwide stakeholder engagement to deliberate on the scope, innovation of technological devices and necessary teacher development for efficient SLE implementation.

Abstract
Background
A 3D printing grid-based method was developed to construct anthropomorphic phantoms with non-uniform activity distributions, to be used for evaluation of quantitative SPECT images. The aims were to characterize the grid-based method and to evaluate its capability to provide realistically shaped phantoms with non-uniform activity distributions.

Methods
Characterization of the grid structures was performed by printing grid-filled spheres. Evaluation was performed by micro-CT imaging to investigate the printing accuracy and by studying the modulation contrast ($$C_{{\text{M}}}$$

C
M

) in SPECT images for 177Lu and 99mTc as a function of the grid fillable-volume fraction (FVF) determined from weighing. The grid-based technique was applied for the construction of two kidney phantoms and two thyroid phantoms, designed using templates from the XCAT digital phantoms. The kidneys were constructed with a hollow outer container shaped as cortex, an inner grid-based structure representing medulla and a solid section representing pelvis. The thyroids consisted of two lobes printed as grid-based structures, with void hot spots within the lobes. The phantoms were filled with solutions of 177Lu (kidneys) or 99mTc (thyroids) and imaged with SPECT. For verification, Monte Carlo simulations of SPECT imaging were performed for activity distributions corresponding to those of the printed phantoms. Measured and simulated SPECT images were compared qualitatively and quantitatively.

Results
Micro-CT images showed that printing inaccuracies were mainly uniform across the grid. The relationships between the FVF from weighing and $$C_{{\text{M}}}$$

C
M

were found to be linear (r = 0.9995 and r = 0.9993 for 177Lu and 99mTc, respectively). The FVF-deviations from the design were up to 15% for thyroids and 4% for kidneys, mainly related to possibilities of cleaning after printing. Measured and simulated SPECT images of kidneys and thyroids exhibited similar activity distributions and quantitative comparisons agreed well, thus verifying the grid-based method.

Conclusions
We find the grid-based technique useful for the provision of 3D printed, realistically shaped, phantoms with non-uniform activity distributions, which can be used for evaluation of different quantitative methods in SPECT imaging.

Published: January 2024

Abstract
Background
Bilberry (Vaccinium myrtillus L.) is one of the most important economic and natural resources in Northern Europe. Despite its importance, the endophytic fungal community of the fruits has rarely been investigated. Biogeographic patterns and determinants of the fungal diversity in the bilberry fruit are poorly understood, albeit fungal endophytes can have a close relationship with the host plants. Here, we investigated the effect of climatic regions, and their weather conditions within growth season and soil properties on fungal endophytic communities of bilberry fruits collected from northern and southern regions of Finland using high-throughput sequencing technology targeting the internal transcribed spacer 2 ribosomal DNA region for fungi.

Results
Species richness and beta diversity (variation in community structure) were higher in the southern compared to the studied northern region. The weather condition of the growth season drove both fungal richness and community structure. Furthermore, abundance of the genera Venturia, Cladosporium, and Podosphaera was influenced by the weather, being different between the south and north regions.

Conclusions
We conclude that diversity and assembly structure of the fungal endophytes in bilberry fruits follow similar patterns as for foliar fungal endophytes, being shaped by various environmental factors, such as the climate and surrounding vegetation.
Dietary diversity and associated factors among women attending antenatal clinics in the coast region of Tanzania
Authors: Heri Rashidi , Malqvist Mats , Yahya-Malima Khadija I. , Mselle Lilian Teddy 
Published: January 2024

Abstract
Background
Antenatal care (ANC) is crucial for reducing maternal morbidity and mortality, especially in low-resource settings. During antenatal care, women are provided with resources for enhancing their dietary diversity, like nutrition education and counseling. Improved nutrition knowledge influences positive nutritional behavior change, like women’s improved dietary diversity, which may increase the likelihood of a healthier pregnancy and delivery experience.

Objective
This study aim was to assess dietary diversity and associated factors among pregnant women attending antenatal care in the Coast region of Tanzania.

Methods
The descriptive cross-sectional study design was used to assess dietary diversity and associated factors among 338 pregnant women. A semi-structured questionnaire collected information from pregnant women on social demographic characteristics, nutrition knowledge and dietary diversity. Women were classified as having a varied diet if they had consumed at least five of the ten food groups over the previous twenty-four hours. Multivariable logistic regression analyses were used to identify predictors of dietary diversity in pregnant women.

Results
Only 28% (95% CI: 23.5–33.1) (n = 95) of pregnant women met the minimum dietary diversity, and 18% (95% CI: 13.8–21.9) (n = 59) were considered to have a high level of nutrition knowledge. Living near a health facility (AOR = 1.77, CI 1.02, 3.06), having high nutrition knowledge (AOR = 2.58, 95% CI: 1.36, 4.89), and being pregnant for the first time (AOR = 2.44, 95% CI: 1.09, 5.44) were associated with adequate dietary diversity.

Conclusion
Pregnant women in the study were found to have low knowledge about nutrition and inadequate dietary diversity intake. The findings underscore the need to improve nutrition knowledge provision in antenatal clinics by emphasizing the importance of a diversified and high-quality diet. Healthcare providers in antenatal care clinics should consistently provide nutrition education and counseling to pregnant women and promote their diversified food consumption. Such knowledge may eventually promote healthier pregnancy and child development by curbing the nutritional deficiencies experienced during pregnancy.

Authors: Ward Susan J. , Coates Alison M. , Baldock Katherine L. , Berryman Carolyn , Hill Alison M. 
Published: January 2024

Abstract
Introduction
Nutrition-related factors linked to pain chronicity and disability include weight status and dietary behaviours. Dietary patterns associated with concurrent pain episodes, however, remain poorly characterised. This paper outlines the protocol for a feasibility study that aims to characterise pain-related dietary and lifestyle behaviours in people experiencing chronic musculoskeletal pain.

Methods
The study will recruit participants who experience musculoskeletal pain on 5 or more days of the week for at least 3 months. Participants will attend two in-person clinic visits where physical measurements and a series of pain and lifestyle questionnaires will be completed. Visits will be conducted pre and post a 2-week self-monitoring period where participants will self-report concurrent diet, sleep, mood, and pain on four days and will wear a wrist-worn activity monitor (GENEActiv). Key feasibility metrics will evaluate participant recruitment, enrolment and retention rates, and compliance with the study data collection protocol.

Discussion
There remains a lack of evidence behind dietary advice as an adjunct pain management tool. Upon completion of the protocol, feasibility outcomes will identify challenges to guide the design and delivery of a dietary intervention for chronic musculoskeletal pain.
Financial markets implications of the energy transition: carbon content of energy use in listed companies
Authors: Mazzarano Matteo 
Published: January 2024

AbstractDecarbonization is often misunderstood in financial studies. Furthermore, its implications for investment opportunities and growth are even less known. The study investigates the link between energy indicators and Tobin's Quotient (TQ) in listed companies globally, finding that the carbon content of energy presents a negative yet modest effect on financial performance. Furthermore, we investigated the effect carbon prices in compliance markets have on TQ for exempted and non-exempt firms, finding that Energy efficiency measures yield greater effects in the latter group. Conversely, it is also true that carbon prices marginally reduce TQ more in non-exempt firms. This implies that auction-mechanisms create burdens that companies are eager to relinquish by reducing emissions. However, reducing GHG yields positive effects on TQ only as long as it results in energy efficiency improvements.
The role of teacher assessment literacy in job stress and job burnout in EFL contexts: a mixed-methods investigation
Authors: Rezai Afsheen 
Published: January 2024

AbstractReviewing the literature reveals that the role of teacher assessment literacy (TAL) in teacher job stress (TJS) and teacher job burnout (TJB) among English as foreign language (EFL) teachers in Iran has remained largely unexplored. As a result, this mixed-methods study investigated the association between TAL, TJS, and TJB in the Iranian EFL context. For the quantitative section, 413 EFL teachers, including 221 males and 192 females, were randomly selected. They completed the Teacher Assessment Literacy Questionnaire, the Teacher Job Stress Scale, and the Teacher Job Burnout Inventory, and the data was analyzed using structural equation modeling. For the qualitative part, 18 EFL teachers who joined the quantitative part participated in a focus group interview, and their responses were analyzed through a content analysis approach. Results indicated that TAL is a strong predictor of TJS and TJB. Specifically, the findings indicated that TAL was positively linked to all the sub-scales of TJS and TJB. Additionally, the complementary qualitative results yielded four themes: TAL promotes job productivity, TAL raises teachers’ social face, TAL enables teachers to manage the class efficiently, and TAL brings positive wash-back. The findings suggest that TAL, TJS, and TJB should be incorporated in pre-service and in-service teacher training courses in EFL education.
What rationale would work? Unfolding the role of learners’ attitudes and motivation in predicting learning engagement and perceived learning outcomes in MOOCs
Authors: Wei Xiaomei , Saab Nadira , Admiraal Wilfried 
Published: January 2024

AbstractThe aim of this study is to gain insight into the interplay between attitudes, motivation, learning engagement, and perceived learning outcomes in massive open online courses (MOOCs). An online survey was administered to 232 MOOC learners. This study provided comprehensive explanations for individual differences in learning engagement and perceived learning outcomes in MOOCs with a modified model of the expectancy-value theory of achievement motivation. The structural equation modeling revealed that attitudes served as a precursor of participation in MOOCs that significantly influenced self-efficacy, intrinsic value, and task effort cost; self-efficacy and intrinsic value were positively associated with both learning engagement and perceived learning outcomes, while attitudes toward MOOC learning was positively related to perceived learning outcomes only. Furthermore, the mediation analyses highlighted that intrinsic value was a powerful mediator, which positively influenced the effects of attitudes and self-efficacy on learning engagement and perceived learning outcomes. The moderation analyses discovered that task effort cost moderated the effects of attitudes on learning engagement and perceived learning outcomes. Curriculum designers and instructors could benefit from this study to understand what rationales drive individuals to be engaged in MOOC learning and to reach greater perceived learning outcomes in MOOCs.

AbstractBackgroundFall armyworm (FAW)Spodopterafrugiperdais regarded as a major pest of various economic crops, their caterpillars are a highly destructive and have a wide host range. The application of traditional pesticides is the main strategies used for its control, that resulting to number of negative impacts of pesticides on the environment and development of pesticide resistance.MethodsThis study’s goal was to assess the insecticide potency of three essential oils [rosemary (RosmarinusofficinalisL.), lemongrass (Cymbopogoncitratus) and Cinnamon (Cinnamomumzeylanicum)] and methomyl lannate 90% commercial insecticide to controlS.frugiperda(fall armyworm) and their effects on expression of caspase-8 and inhibitor of apoptosis protein genes and expression of acetylcholinesterase (AChE) gene in fall armyworm (FAW).ResultsThe insecticidal activity against second larval instar of fall armyworm was evaluated with five concentrations (2.5%, 2%, 1.0%, 0.5% and 0.25%) for essential oil and four concentrations 0.4%, 0.2%, 0.15% and 0.05% for methomyl lannate 90%. The findings indicated that raising both essential oil concentrations and methomyl lannate 90% resulted in increased larval mortality at high concentration. The expression levels of Ache gene treated by low dose (0.3 µ/L) of methomyl lannate were increased (by 313%) significantly compared with the control but without significant differences.ConclusionsThe tested essential oils showed insecticidal activity against the second larval instar ofS.frugiperdadeath as a result of treatment with the tested oils having an effect on the genes that the pest uses to express critical processes (genes of apoptosis).

Abstract
Background
Recently, attention has been directed toward the use of osteoinductive biomaterials in combination with stem cells for possible application in repair of bony defects. Blood products, namely platelet-rich fibrin (PRF), have been widely used nowadays owing to their wide range of advantages. Gingival mesenchymal stem cells (GMSCs) also recently have been utilized and considered as a highly promising alternative source, eliminating a lot of the drawbacks faced by stem cells derived from the bone marrow. The present study aimed to compare the proliferative and osteogenic effect of PRF, on both GMSCs and BM-MSCs. BM-MSCs and GMSCs were cultured in osteogenic media in combination PRF for two weeks. Following culture, MTT assay was conducted to assess the proliferative capacity of both types of cells after subjection to PRF. Osteogenic differentiation was assessed by Alizarin red staining in addition to OSN and Runx2 gene expression by RT-qPCR.

Results
PRF proved to have a positive proliferative effect, especially on GMSCs, compared to BM-MSCs. PRF also demonstrated a positive osteogenic inductive effect on both stem cell types, but its effect seemed to be more pronounced when combined with GMSCs.

Conclusions
PRF proved to be a promising and potent inducer of proliferation and osteogenesis when used in combination with stem cells, especially when combined with GMSCs.

Authors: Couissi Abdessamad , Haboub Meryem , Hamady Siyam , Ettachfini Taha , Habbal Rachida 
Published: January 2024

Abstract
Background
Heart failure (HF) poses a significant public health challenge throughout the world and Morocco. Our objective was to delineate the epidemiological characteristics of Moroccan patients living with chronic heart failure and to identify prognostic factors correlated with CHF mortality.

Results
A total of 1344 patients participated in this study, with survival rates at 3, 6, and 10 years recorded at 75.2%, 60%, and 34%, respectively. During the follow-up, 886 patients succumbed, representing a mortality rate of 65.9%. A Cox regression model, utilizing baseline candidate variables, was developed to predict cardiovascular (CV) mortality. Predictors all of which had a P value less than 0.05 included age, left ventricular ejection fraction (EF) at commencement (< 35%), hypertension, male sex, anemia, creatinine levels, and the number of hospitalizations due to HF decompensation. Notably, the frequency of hospitalizations emerged as the most potent predictor of mortality, with an HR of 2.5 (95% CI [2–2.9]). Almost 90% of patients with three or more readmissions for HF decompensation experienced mortality by the follow-up’s conclusion.

Conclusions
This study offers valuable insights into risk factors and clinical outcomes in HF patients in Morocco. Factors such as male gender, advanced age, a history of hypertension, lower systolic blood pressure, rehospitalizations for HF decompensation, low left ventricular ejection fraction, anemia, and elevated creatinine levels were associated with increased mortality. Medical and health services managers should be aware of the substantial burden and future challenges posed by HF in Morocco, prompting the adoption of multidisciplinary strategies for its management and care.
