Authors: Basu Abhijit , Joshi Piyush , Sharma Asha
Published: February 2025

To compare thyroid profile in pre- eclamptic patients and normal normotensive pregnant women in between gestational age of 28-40 weeks of pregnancy.

This case control study was done from Dec. 2015 to June 2017 in Geetanjali Medical College & Hospital, Udaipur. It was done on 50 patients of preeclampsia (case group) and 50 normal pregnant women (control group) in between gestational age of 28-40 weeks of pregnancy.

Mean T 3 between case and control group was not statistically significant with p value = 0.844. Mean T 4 between case and control group was statistically significant with p value = 0.011. Mean TSH between case and control group was statistically significant with p value = 0.00068. Prevalence of hypothyroidism in patients of preeclampsia was 44% as compared to 16% in control group and p value was 0.00225, which was statistically significant. If the titers of TSH were above 4.04 μIU/ml in between gestational age of 28-40 weeks of pregnancy then there was 4 times higher risk of the development of preeclampsia.

Present study suggested that pathogenesis of preeclampsia is related to primary hypo-functioning of the thyroid. Severity of preeclampsia correlated with modest decreases in thyroid hormones along with increased TSH level.

Published: February 2025

:Premature rupture of membranes (PROM) is defined as the spontaneous rupture of membranes before the onset of labor. It is associated with various adverse outcomes including maternal and perinatal morbidity and mortality. Chorio-amnionitis, placental abruption, post-partum hemorrhage, puerperal sepsis, oligohydramnios, cord prolapse, fetal distress, intra-uterine death, perinatal infections are some of the complications associated with it.

To evaluate the feto-maternal outcome in PROM.

It was a prospective cohort study conducted in the Department of Obstetrics and Gynaecology, Regional Institute of Medical Sciences, Imphal, Manipur for one and half years from January, 2021 to June, 2022. A total of 170 pregnant women were included in the study- 85 women with PROM and 85 without PROM. Inclusion criteria includes gestational age of at least 37 completed weeks, lack of uterine contractions for at least one hour after PROM, cervical dilatation less than 3 cm, single live pregnancy in vertex presentation, and PROM confirmed by direct visualization under speculum examination. Exclusion criteria includes mal-presentation, multiple gestation, meconium stained liquor, cephalo-pelvic disproportion.

Respiratory distress syndrome was found to be more in babies born to women with PROM, as compared to the babies born to women without PROM, with a relative risk of 1.5. There was no statistically significant association of PROM with neonatal sepsis, NICU admission of new-borns, APGAR score of babies, chorio-amnionitis, or puerperal sepsis.

This prospective study was carried out to suggest some strategies for proper screening of high-risk cases, correct diagnosis and effective management and thus improvement of maternal and neonatal outcome. Although early diagnosis and proper management can be helpful in decreasing prenatal morbidities in cases of PROM, more randomized controlled trials involving larger sample size is required to draw further conclusions.

To study the clinical profile and outcome of thrombocytopenia in pregnancy.To study the etiologies of thrombocytopenia in pregnancy. To study the maternal and perinatal outcome in thrombocytopenia in pregnancy.

This is an observational retrospective study in which 200 pregnant women who had thrombocytopenia were recruited from department of obstetrics and gynecology at Gandhi hospital.

The present study gives information about the etiology of thrombocytopenia in pregnancy and fetomaternal outcome. Out of 200 cases, 88 cases belongs to pregnancy induced hypertension which is considered as the most common etiology followed by gestational thrombocytopenia. Incidence of abruption was significantly high mainly in pregnancy induced hypertensive cases. The maternal and perinatal complications were lower in gestational thrombocytopenia compared with other etiologies. High rates of preterm deliveries were observed among women with hypertensive disorders. Adverse perinatal outcome was mostly associated with hypertensive disorders especially HELLP syndrome.

The common cause of thrombocytopenia in pregnancy in this study is mainly hypertensive disorders. Patients with gestational thrombocytopenia have favorable maternal and perinatal outcome. On the other hand, preeclampsia and HELLP syndrome are associated with adverse perinatal outcome like IUGR and intrauterine fetal death.

Published: February 2025

One of the primary reasons why infertility is on the rise is Polycystic Ovarian Disorder or PCOD. It is a chronic disorder in which many benign cysts form on the ovaries. It affects about 3%-7% of women of reproductive age. It most commonly in women under 30 years old and is a commonest cause of anovulation and a leading cause of infertility. Although the precise origin of PCOD is yet unclear, genetics and hormone abnormalities are thought to have a role. In some cases, it can even run-in families. Now a days most of the adolescent girls are found suffering from PCOD due to bad food habits, sedentary lifestyle and also stress and it will affect their quality of life. Hence the researcher selected this topic for the study.

: The aim of the study was to assess the effectiveness of structured teaching programme on knowledge regarding polycystic ovarian disorder among adolescent girls studying in SGRR College of nursing Patel Nagar, Dehradun.

: One group pretest post-test design was adopted to evaluate the effectiveness of planned teaching program on PCOD. The sample was collected using convenient sampling technique. 60 adolescent girls of age 18-21 years were selected, [sample size was calculated with the help of Yamane’s formula n= N/ (1+Ne2)] out of which 57 girls were taken from Basic B.Sc. Nursing 1 year and 3 girls from GNM 1 year. A self-developed knowledge questionnaire consisting of 30 multiple choice questions regarding PCOD was used to collect data.

The pre-test showed that 66.7% of girls had inadequate knowledge whereas after the structured teaching programme 18.4% had inadequate knowledge. In pre-test 28.34% of girls had moderate knowledge whereas 40% girls had moderate knowledge after exposure to planned teaching programme. Before the planned teaching programme very few 5% girls were having adequate level of knowledge whereas after exposure to structured teaching programme, 41.6% girls attained adequate level of knowledge. Thus, the study concluded that most of the students attained adequate knowledge after the structured teaching program which was found statistically significant (at the level of p< 0.05).

Authors: Kaur Manpreet , Sood Reena , Pahwa Sangeeta
Published: February 2025

Vitamin D deficiency during pregnancy is a worldwide epidemic. Studies have reported a prevalence that ranges from 18-84%, depending on country of residence, season and local clothing customs. Furthermore studies have shown that pregnancy alone is a risk factor for vitamin D deficiency particularly among women living at high altitudes.Vitamin D deficiency in pregnancy is associated with increased risk of pre eclampsia, gestational diabetes mellitus, preterm birth, small for gestational age infants, impaired fetal skeletal formation and bone mineral density (BMD).

Aim of our study is to assess vitamin D levels in antenatal patients in first trimester attending OPD at a tertiary care centre.

: It is a cross-sectional study that was conducted in department of OBG at SGRD, Sri Amritsar. All participants meeting inclusion criteria were enrolled for the study and written informed consent was taken. Serum sample of the eligible primigravida was taken at time of recruitment, centrifuged and stored at -70 degrees for assessment of serum 25 hydroxy-vitamin D level.

: A high prevalence of vitamin D deficiency was observed in our study population where only 18.8% had adequate levels of vitamin D while 81.2% of the participants had vitamin D deficiency (69% were insufficient and 12.2% were severe deficient), and none of the participants was having vitamin D toxicity. The deficiency was equally high in all age groups of study participants irrespective of their area of residence. The mean serum calcium in severe deficient and adequate group was 7.97±0.61 and 9.22 ±0.63 respectively (p=0.001). Similarly mean serum phosphorus levels in severe deficient and adequate group is 3.03±0.79 and 3.60±0.63 respectively (p=0.001). Maternal education, socioeconomic status, obesity, serum calcium and serum phosphorus levels were significantly associated with severe vitamin D deficiency.

: Vitamin D deficiency is highly prevalent among pregnant women who participated in our study, which raises concern about the health consequences for the mother and the offspring.

Given the exponential rise in preterm births around the globe, this study aims to know prevalence of overall preterm births and among different categories as well as to analyse the risk factors responsible for preterm birth in different categories.

This cross-sectional study was conducted in Dr. Prabhakar Kore Charitable Hospital, Belagavi from June 2021 to May 2022. The risk factors were classified into extreme preterm, very preterm and moderate to late preterm. Chi-square test was used to check the dependency between categorical variables. Odds ratio was calculated for knowing the association of different risk factors with type of preterm birth.

Among 3413 women, there were 588 (17.67%) preterm births. 479(81.46%) were in moderate to late preterm category, 71 (12.07%) were very preterm and 38(6.46%) were extremely preterm. Odds of extreme preterm for maternal single kidney, congenital anomalies, covid infection, fetal growth restriction, preeclampsia, still birth, hypothyroidism were 65.68 [95% CI: 3.09-1393.85], 10.22[ 95% CI: 3.08 -33.94], 7.93 [95% CI: 2.21-28.44], 2.83 [95% CI: 1.37-5.90], 2.42[95% CI:1.42-4.10], 2.16 [95% CI: 1.13 -4.13], 3.14 [95% CI: 1.5-6.35], 1.86 [95% CI: 0.94-3.73] respectively when compared with moderate to late preterm group.

The prevalence of preterm birth was 17.6%. The risk factors should be controlled in pre conceptional period and early pregnancy to reduce preterm births.
First trimester serum uric acid as an early predictor of gestational diabetes mellitus
Authors: Bhattacharya Aritri , Patil Hema Sharanagouda
Published: February 2025

First identified during pregnancy, GDM (Gestational diabetes mellitus) is referred by reduced glucose tolerance that results in varied degrees of hyper-glycemia. Usually, the diagnosis is made between twenty four to twenty eight weeks period of gestation. Compared to European women, South Asian, and especially Indian women have an 11 times elevated chance of developing GDM. GDM women are more prone to operative vaginal deliveries, cesarean sections, and complications such as shoulder dystocia during vaginal delivery due to the fetus having macrosomia or large for gestation. Screening and diagnostic methods for GDM depend largely on historical data, clinical examination, and laboratory tests like DIPSI and IADPSG. Early detection and prevention methods for GDM are limited. The purpose of this study was to evaluate the predictive value of serum uric acid levels in the first trimester for GDM in low-risk pregnant women.

: Following obtaining permission, the level of serum uric acid had been measured from blood samples obtained from low-risk pregnant women. DIPSI testing was done twice, once between the weeks of gestation of 24 and 28 and then again between 28 and 32 weeks of gestation. Regression analysis employing receiver operating characteristic (ROC) curves and logistic regression was used to evaluate serum uric acid's capacity to predict GDM. The Youden index was utilized to establish the cut-off values. A statistically significant result was defined as having a p-value of <0.05.

: 106 patients who met the study's inclusion criteria were included. The level of Serum uric acid in the 1 trimester had an AU-ROC of 0.8316 with a cut-off > 3.4 mg/dl, meaning 74.70% sensitivity and 82.61% specificity for GDM prediction. Serum uric acid and GDM showed a significant correlation (p < 0.001), according to logistic regression. Individuals whose level of serum uric acid is >3.4mg/dl had 14.02 times greater odds of suffering from GDM (95% CI: 4.28 - 45.92) than those with serum uric acid ≤ 3.4.

: A one-year observational study conducted at the Dr. Prabhakar Kore Charitable Hospital and Research Centre, Belgaum, on behalf of KAHER revealed that the improvement of GDM can be predicted early with a 1 trimester serum uric acid cutoff of higher than 3.4 mg/dl.
Rare benign vulvar tumours: Case series
Authors: Kiruthika T
Published: February 2025

Vulvar tumours are rare benign lesions of the lower genital tract, frequently prompting gynaecological consultations. This case series explores three distinct presentations: vulvar angiofibroma, phyllodes tumour of the vulva, and haemangioma of the vulva, each illustrating unique diagnostic and management challenges. Vulvar tumours often mimic other pathologies, necessitating comprehensive clinical and pathological evaluations to distinguish between benign, pre-malignant, and malignant stages. Common imaging modalities employed include ultrasound and MRI, which aid in preliminary assessments and guide further invasive diagnostics. Histopathology usually confirms the diagnosis. Treatment typically involves surgical excision, with the extent depending on the tumour type and its characteristics. Prognosis is generally favourable, but follow-up is crucial for monitoring recurrence or potential malignant transformation. Recurrence varies, with phyllodes tumours showing a higher recurrence rate if not completely excised, whereas angiofibroma and haemangiomas are less likely to recur. This case series underscores the importance of accurate diagnosis and tailored management strategies in optimizing outcomes for patients with these rare vulvar tumours.

Published: February 2025

Ovarian cysts are a common incidental finding during pregnancy, often presenting a diagnostic and management challenge due to concerns regarding maternal and fetal outcomes. This case series aims to explore the management strategies and outcomes of ovarian cysts detected during pregnancy. A total of 5 cases were included in the case series. The mean maternal age was 25 years, with cysts predominantly identified in the second trimester. The majority of cysts were simple or functional. Diagnostic ultrasound was the primary modality for cyst characterization. Management strategies varied from expectant management to surgical intervention depending on cyst size, symptoms, and growth patterns. Maternal complications were rare, with 1 case showing ovarian torsion. Fetal outcomes were favorable, for 3 out of 5 cases. This case series highlights the importance of tailored management approaches for ovarian cysts detected during pregnancy. Conservative management is generally safe, with favorable maternal and fetal outcomes observed in most cases. Close surveillance with serial imaging remains crucial to monitor cyst progression and guide clinical decision-making. Further prospective studies are warranted to establish evidence-based guidelines for optimal management of ovarian cysts in pregnant patients.

Strengthening the National and Religious Identity of Adolescents Through Teaching Monotheism in the Form of Edutainment in Television Programs
Authors: Yavari Ata , Hosseini Seyyed Bashir
Published: February 2025

Aim: Religion, and, in general, culture are among the most important components of national identity worldwide. Islam is considered one of the primary criteria for the national identity of Iranians. Therefore, strengthening national identity is somewhat linked to reinforcing religious foundations. Among these religious foundations, beliefs serve as the underlying base, and within the principles of belief, monotheism is regarded as the most important element. This article aims to identify the requirements and methods for teaching monotheism to adolescents through edutainment and television programs to enhance their national identity. Methods: Part of the research related to the foundational issues was conducted using documentary and library methods, while the upper-level research, due to a lack of library resources and the novelty of the concept of edutainment in our academic literature, utilized in-depth interviews with experts and specialists. In-depth and targeted interviews were conducted with specialized experts. After conducting the interviews and going through the stages of recording and documentation, the desired data was obtained Findings: In our religious and national culture, numerous uses have been made of this strategy. Since the concept of monotheism is the highest element among Islamic teachings and exists like a soul within the body of all Islamic regulations, it is essential to avoid oversimplifying its education. Shallowing this concept is harmful, and care must be taken to preserve it. Balancing entertainment and education, as well as accurately and correctly understanding today's youth, are also essential requirements in this matter.
Mercado de trabalho, discriminação racial e Justiça do Trabalho no Estado do Rio de Janeiro: o racismo como tema residual?
Authors: Santos Sales Augusto dos
Published: February 2025

Este artigo descreve e analisa três dos quatro processos sobre discriminação racial no ambiente de trabalho que foram ajuizados por trabalhadores/as contra quatro empresas, entre 1995 e 2005, no Tribunal Regional do Trabalho da 1ª Região-TRT01, localizado no Estado do Rio de janeiro, mas que chegaram à última instância da Justiça Trabalhista, o Tribunal Superior do Trabalho (TST). Constata-se que há disparidade entre um considerável índice de discriminação racial no mercado de trabalho nacional e a baixa quantidade de denúncias pelos/as trabalhadores/as do crime de racismo junto à Justiça do Trabalho, especialmente na do Rio de Janeiro. Como o escopo de fontes primárias é reduzido para o caso do TRT01, não concluiremos, isto é, descreveremos e analisaremos um resultado concreto, mas levantamos a hipótese de que o tema racismo contra os/as trabalhadores/as negros/as foi tratado de forma residual e/ou marginal pelos membros da Justiça do Trabalho, no período supracitado, o que tem prejudicado sobremaneira esses/as trabalhadores/as não somente no Estado do Rio de Janeiro, mas em todas as Unidades da Federação. Pensamos que essa a limitação de dados primários não inviabiliza a necessidade de uma reflexão séria sobre o tema racismo na Justiça Trabalhista do Rio Janeiro, até porque ela precisa ser feita, inclusive para que este assunto não continue marginal na Justiça do Trabalho como um todo.

Authors: Ma Yiming , Suo Yuan , Wang Mingjiu
Published: February 2025

Background: Saline-alkali soil seriously restricts plant growth. Caucasian clover (Trifolium ambiguum Bieb.) is a high-quality leguminous forage with strong adaptability and stress resistance. However, current research on Caucasian clover under saline-alkali stress remains limited. The purpose of this study is to use NaHCO3 solution to carry out alkali stress on Caucasian clover plantsand to understand the changes of plant growth and physiological characteristics under stress, which is of great significance for its popularization and cultivation in alkaline soil. Methods: To study the effects of alkaline stress on the growth and physiological characteristics of Caucasian clover, plants were subjected to varying concentrations (0, 50, 100, 150, 200 mmol/L) of NaHCO3 in pot experiments. Post-stress, parameters such as dry weight, root-to-shoot ratio, main root length, chlorophyll, malondialdehyde (MDA) contentand the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were measured. Result: This study demonstrated that alkaline stress significantly affected the growth and physiological characteristics of Caucasian clover. With increasing alkaline stress, the aboveground and underground dry weights, as well as the main root length, decreased significantly. Photosynthesis was inhibited, with chlorophyll content increasing under low alkaline stress but decreasing sharply at higher concentrations. The activities of antioxidant enzymes (SOD, POD, CAT) increased significantly under low stress but gradually decreased under higher stress levels. Meanwhile, MDA content increased significantly under high alkaline stress. Correlation analysis showed a strong positive correlation between SOD activity and CAT activity, as well as between aboveground dry weight and main root length (P less than 0.01), while chlorophyll content was negatively correlated with MDA content (P less than 0.05).

Authors: Wang Sally , Galvan Shirchie Iris
Published: February 2025

Background: The removal methods of adhesive resin remain a subject of debate among researchers regarding the most effective approach for reconditioning debonded brackets from the tooth.
Objectives: The aim of this study was to evaluate the micro sandblaster and direct flame technique for removing adhesive remnants from debonded orthodontic metal bracket bases.
Method: The research design was experimental and involved comparing the micro sandblaster and direct flame technique in removing adhesive remnant using purposive sampling. Thirty (30) metal brackets were divided into two groups and soaked for 24 hours in an incubator before applying the two methods of removal. The samples were examined in optical microscopy, and the areas of adhesive remnants were analyzed and measured as a percentage of the digital images using the ImageJ analysis software function. Pixels were converted into millimeters (mm). Statistical analyses, including Shapiro-Wilk Test, Levene’s Test, and T-Test for Independent samples were conducted.
Results: The micro sandblaster group exhibited the lowest mean value at 1.518 mm +1.159 (mean + standard deviation), while the direct flame group showed the highest value at 2.264 mm +1.262. The Levene’s Test result was 0.079, and the T-Test for Independent Samples yielded a p-value of 0.103 which exceeded the predetermined significance level of 0.05.
Conclusion: The results of this study indicate that the micro sandblaster and direct flame techniques for removing adhesive residues from debonded metal brackets showed statistically insignificant differences.  Either of these methods may be a viable approach for operators to use when reconditioning dislodged brackets.

Published: February 2025

Nowadays, investment has major importance for future contingencies. The millennials are one that currently take over a large number of capital market investors. To advocate optimal and sustainable decision-making in stock investment, it is important to explore the determinants of investment decisions which include financial literacy, financial self-efficacy, and risk perception. The study was conducted to assess the influence of financial literacy, financial self-efficacy, financial technology literacy, and risk perception on stock investment decisions in the millennial generation of Yogyakarta Special Region. The population of this study was millennial stock investors in the D.I. Yogyakarta province. The sample is used with criteria that age in between investing 28–43 years old; namely 115 people. The data was collected via a survey strategy and then analyzed using the SEM-PLS technique. Based on the research findings, it can be concluded that financial literacy has a significant positive effect on stock investment decisions among the millennials in Yogyakarta. Conversely, financial self-efficacy negatively impacts stock investment decisions significantly. Additionally, financial technology literacy also demonstrates a positive and significant influence on stock investment decisions. In contrast, risk perception does not appear to affect stock investment decisions among millennials in Yogyakarta. Theoretical and practical implications are discussed in the last section of this article.
Does motivation theory really play any significant role on explaining university teachers’ performance: Understanding Bangladeshi context
Authors: Sultana Rebaka , Faruk Mohammad , Islam Md. Saiful , Khaled Md. Asif
Published: February 2025

The development of human capital is significantly impacted by the way teachers nurture and expand their students' intellectual capacity. The motivation of teachers is a crucial determinant of their performance, and consequently, it influences the success and achievements of their students. In the context of Bangladesh's tertiary education system, the purpose of this study is to look into the implications of motivational theories on explaining and improving university teachers' performance. Along with the Maslow's and Herzberg's needs theory, there are other motivation theories and this study will investigate the current aspects that affect teachers' performance. A convenience sample of 200 randomly chosen informants is obtained via structured survey. To evaluate the study's hypotheses, factor analysis is used. The results indicate that most instructors in Bangladesh lack intrinsic motivation, which has no visible impact on their performance. Conversely, extrinsic incentive and instructors' performance are positively and significantly correlated. The whole basic wage package seems to have the greatest influence on teachers' motivation among all other elements. Finally, the study recommends that stakeholders should prioritize and enhance incentives, putting an emphasis on sustainable development to raise living standards in rural areas for teachers to boost their level of motivation and performance.

Published: February 2025

We present new data on the composition and U–Pb (LA-ICP-MS) age of detrital zircons from the Carboniferous sedimentary rocks of the Siberian Platform cover, in which diamonds and accessory minerals were found, namely, the Baeronovka Formation in the southwest and the Tushama and Kata formations at the center of the Siberian Platform. The geochemical characteristics and results of analysis of minerals of the heavy fraction from the Baeronovka Formation indicate a predominantly felsic composition of the provenance rocks. The latter are, most likely, the rocks of the Cis-Sayan uplift of the Siberian Platform basement, including mostly Paleoproterozoic granitoids and volcanic rocks of the South Siberian postcollisional magmatic belt. Smaller amounts of detrital material got into the sedimentation basin of the Baeronovka Formation through the destruction of early Paleozoic rocks at the northern segment of the Central Asian Orogenic Belt. The geochemical characteristics of the terrigenous rocks of the Carboniferous Tushama and Kata formations testify to a felsic composition of the provenance rocks, but the mineral compositions of the heavy fractions indicate different compositions of these rocks. These data and the age of detrital zircons suggest that the Neoproterozoic sedimentary rocks and middle Paleozoic igneous rocks of the Baikal–Patom zone on the southern margin of the Siberian Platform and the Middle Paleozoic igneous rocks of the Vilyui rift and the Yakut diamondiferous province are the main provenances for the Tushama and Kata formations. The established differences in the composition and age of provenance rocks for the Carboniferous sandstones of different areas of the Siberian Platform confirm the earlier conclusions about the existence of several local sedimentary basins within it in the Devonian–Carboniferous. These basins formed after the middle Paleozoic tectonomagmatic activity accompanied by diamondiferous lamproite and kimberlite magmatism.

This paper presents the basic principles of recording processes occurring in the Earth’s crust during the occurrence and development of catastrophic phenomena using an earthquake as an example; these principles allow one to determine the coordinates of the source and epicenter. Basic approaches are revealed to creating a laser interferometric seismoacoustic observatory (LISO) designed to monitor continental-scale seismic events. This study also describes the instrumental equipment (laser and optical strainmeters, accelerometers, and hydrophones) developed and used at the Institute of Automation and Control Processes FEB RAS, the V.I. Il’ichev Pacific Oceanological Institute FEB RAS, and the O.Yu. Schmidt Institute of Physics of the Earth RAS; this equipment is intended for use in the LISO.

This study investigates the mechanical properties of hybrid composites reinforced with bark cloth (Ficus natalensis) and glass fiber in a polyester resin matrix. Composites were fabricated using the hand layup technique with varying fiber weight fractions (15%, 20%, and 25%) and hybrid ratios (3:1, 2:2, 1:3). The influence of hybrid ratio and stacking sequence on flexural, tensile, compressive, and impact strengths was evaluated. Results indicated that composites with higher glass fiber content exhibited superior mechanical performance, with optimal flexural (140.94 MPa), tensile (43.24 MPa), compressive (26.47 MPa), and impact strengths (32.44 kJ/m²) at a 1:3 hybrid ratio. Hybridization improved the mechanical properties of the composites, particularly flexural strength, which was significantly affected by stacking sequence. These findings suggest that bark cloth/glass fiber hybrid composites have potential for applications in automotive and structural industries.
Learning to Notice Critical Moments in L1 Teaching: The potential of video-based mentoring conversations during fieldwork
Authors: Brataas Gøril
Published: February 2025

This study argues that to educate first language (L1) teachers who are responsive to students’ needs, we must pay attention to the invisible but fundamental processes of teacher noticing. Teacher noticing—how teachers perceive, interpret, and make decisions about how to respond to student ideas and needs during teaching—is scarcely studied within language and literature education. In this qualitative study, I examine the characteristics of mentoring conversations in which teacher candidates and their mentors discuss videos of the candidates’ L1 teaching in terms of the critical moments (Myhill & Warren, 2005) they attended to, their interpretations of these critical moments, and their decision-making on how to respond to these moments. The findings show that the candidates and mentors attended to various opportunities to scaffold student text production and interpretation, as well as opportunities to elicit and respond to student ideas in text-based discussions. Adopting an evaluative stance toward these critical moments supported the candidates in identifying alternative teaching moves, while adopting an inquiry stance led them to identify the first paths toward more adaptive teaching. These findings suggest that video-based mentoring conversations have the potential to support L1 teacher candidates in learning to notice and have implications for teacher education coursework and fieldwork.
Research-based projects and reflective journals to promote student engagement in a remote online English Linguistics course for Professional Business Communication
Authors: Cucchi Costanza
Published: February 2025

The Covid-19 pandemic spurred research on the strategies and tools used in remote online teaching to support student engagement. The present study aims to contribute to this research strand by illustrating how two tools that were implemented for this purpose, i.e. research-based projects and reflective journals, were integrated in a remote online English Linguistics course for Professional Business Communication during the pandemic. A content analysis of students’ perceptions was conducted through the N-Vivo software programme and feedback on the course was examined. Results indicated that projects and journals positively impacted on students’ skills, knowledge and attitudes by enhancing interest and reducing the sense of isolation resulting from the lockdowns. It is therefore suggested that research-based projects and journals potentially support student engagement in learning settings which may negatively affect engagement, such as remote online courses.

The performance of PV systems is highly dependent on climatic hazards (wind, dust, low sunshine, etc.). Some of these hazards can even accelerate its degradation process during its life cycle if nothing is done in terms of maintenance policy. This paper aims to model the degradation process of PV systems under environmental conditions. To do this, a system study is first performed to analyze the experimental data of the PV system in question according to the location of the site and simulated under the PVsyst software to extract the parameters of the study. In a second step, taking into account the Markovian approach, passing rules are established to design our dynamic Bayesian model. To this model, we have integrated a maintenance policy decision node and performance indicators in order to reproduce the degradation process in the real context and under stress. We have associated the decision node to enable AI integration through reinforcement learning on this node.The simulation results effectively reproduce the behavior of the PV system under environmental stress according to several scenarios (with or without IA). Furthermore, simulation allows us (a) to observe and validate the experimental values taken during the tests on the PV, (b) to see their availability increase with reinforcement learning compared to the case without learning. At the same time, we note that the increase in this availability leads to a relative decrease in income. The model allows to evaluate the performance of the system and propose the bestmaintenance policy configurations according to the input parameters (transition parameters, maintenance cost).
