Sign reversal of the spontaneous and induced polarisation in a mixture of achiral liquid crystal host and chiral azo dopant
Achiral liquid crystal, possessing orthogonal smectic A and tilted smectic C phases in its phase sequence, was doped with a chiral photochromic azo dopant. It was found that the spontaneous and induced polarisation in the tilted smectic C* phase and in the orthogonal smectic A phase, respectively, change their sign, as well as their magnitude, under illumination with UV light. The origin of this sign reversal effect is considered to be the different sign of the molecular net dipole moment component y of trans- and cis-isomers of the photochromic azo dopant, respectively. This light-induced sign reversal effect seems to have large potential for applications in the light-light controlled photonic liquid crystal devices, based on this effect. 2023 The Author(s).

Can we improve the outcome of pregnancies with low serum PAPP-A in the first trimester?
Low birth weight is associated with various complications, and recent findings rely on the fact that micronized progesterone supplementation leads to improved birth weight, which is crucial for addressing concerns related to fetal growth. Objective: This study aimed to assess the impact of micronized progesterone (VMP4) supplementation on pregnancies with low serum pregnancy-associated plasma protein-A (PAPP-A) multiples of the median (MoM) values during first-trimester screening. Methods: Out of 8933 patients evaluated, 116 pregnant women with low PAPP-A concentrations in their blood and no fetal chromosomal anomalies (CAs) were included. Three groups were formed: group 1 received VMP4 from 11 to 16weeks (29 women, 25%), group 2 received VMP4 from 11 to 36weeks (25 women, 21.5%), and group 3 (62 women, 53.5%) served as controls without receiving progesterone. Results: Results indicated that group 3 had higher rates of complications, including miscarriages (16.37%), preterm delivery (17.8%), and fetal developmental abnormalities (19.4%). Birthweight variations were elevated in pregnancies without progesterone, contrasting with lower variations in VMP4 groups. Group 2, receiving VMP4 until 36weeks, reported the lowest incidence of abortion and preterm birth (PB), along with the highest mean birth weight. Conclusions: The conclusion suggests that 200 mg per day of VMP4 up to 36weeks of supplementation led to fewer placental-related complications in women with very low PAPP-A at first-trimester screening (0.399 MoM). By reporting lower rates of miscarriages, PBs, and fetal developmental abnormalities in the micronized progesterone-treated groups, the study suggests a potential reduction in complications. 2024 The Author(s).

Receptivity to Change, Work Motivation, and Teacher Engagement among Secondary School Teachers
The present study investigated the teachers receptivity to change in relation to work motivation and teacher engagement among secondary school teachers in Kerala, India. The study primarily focussed on the newlinedevelopment and validation of the Teachers Receptivity to Change Scale. The way the teachers receive the change is a vital determinant that defines the successful execution of the change. The present study used a mixed-methods sequential explanatory design, which proceeded through three phases. The tool construction, which progressed through five stages namely, item analysis, exploratory factor analysis, confirmatory factor analysis, validity assessment, and test-retest reliability, constituted the newlinefirst phase. The development of the tool started with the generation of a pool of items followed by item analysis. The exploratory factor analysis extracted four factors and the confirmatory factor analysis confirmed the four factors namely individual, organizational, educational, and bridging newlinefactors. The structural equation modelling corroborated that the scale excellently fits in the four-factor correlated model and indexed receptivity to change as the sum of the four factors. The final 28-item Teachers newlineReceptivity to Change Scale showed adequate internal consistency (Cronbach s and#945; = .90) and discriminant validity. The validity assessment indicated a moderate correlation between receptivity to change, work motivation, and teacher engagement. The test re-test reliability analysis (Cronbach s and#945; = .88) confirmed the temporal stability of the scale. In the second phase, a sample of 433 secondary school teachers of Kerala, newlineresponded to the standardised questionnaires namely Teachers Receptivity to Change Scale, Multidimensional Work Motivation Scale, newlineand Engaged Teachers Scale. The study also assessed the influence of demographic characteristics such as gender, type of institution, age, subject taught, and years of experience using the Mann-Whitney U-test, newlineand Kruskal-Wallis test. -
Work Tasks Motivation in Relation to Occupational Self-Efficacy and Thinking Skills of Secondary School Teachers
Education is a dynamic enterprise which is centred on the processes of teaching and learning. All the systems that are connected with the education of an individual should be taken care of for the betterment of the teaching-learning process. Teachers are one of the important sources of inspiration for the students. Every aspect of the teaching-learning process such as the instructional strategies, assessments, student management, the environment etc. has been changing due to the technological innovations and social advancements. The teachers have to be equipped with new technologies that will lead to innovations in education methodologies. The development of necessary skills and belief in their profession is essential for motivating teachers to adapt and adjust to the challenges, the changing attitudes and habits of children. Also, the teachers are expected to perform multiple tasks rather than a particular one. The present study aimed at assessing the types of motivation towards specific work tasks, efficacy towards their occupation and thinking skills of secondary school teachers of Bengaluru. The study reported that Intrinsic Motivation and Identified Regulation led to positive outcomes whereas Introjected, External Regulations and Amotivation led to negative results. The demographic variable, gender had no significant effect on the variables under the study. A significant difference was found for the types of motivation for specific tasks with respect to subject specialisations, types of management, and years of experience. The study thus gives an insight into the motivational processes of a teacher which will be helpful in creating a positive work environment. -

Nurturing a Better Future for Best Schooling Practices: A Review Portraying the Alternative Schooling, Bangalore, Karnataka, India
Schooling is an essential stage in the socialization of a child. Schooling has a direct effect on a child's educational achievement, acquisition of skills, social cognition, and feelings (Sylva, 1994). Every schooling practice has the potential to mould the child and shape future citizens. Today many different schooling practices are prevailing in India. However, the majority of these schooling practices focus more on the cognitive development of the child and nurtures the values of competition and insecurity among the children. The schools have turned into factories that bring out mechanical individuals who cannot question, express, and voice themselves but who can only become a part of the race of obtaining marks and jobs. This kind of schooling may help in increasing the literacy rates but has not helped in producing truly educated and ethical citizens. It has led to moral degradation in society (Parihar, Parihar & Sharma, 2018). In this context, it is imperative to analyse the alternative schooling practices that nurture a better future. One such school that educates the heart, allows the flowering of the child and nurtures good citizens is the Valley School, Bangalore. Through this article, an attempt has been made to present a description of prevailing schooling practices and the challenges faced in the educational context. The authors put forth a review of schooling practices at valley school, one of the best alternative schools and ignite the discussion on Valley school being the best in nurturing a better future. 2020 Horizon Research Publishing.

Student alienation and perceived organizational culture: A correlational study
It is generally expected that the students are supposed to gain an engaging and enriching experience throughout their journey of higher education. The educational institutions have to take up the responsibility to ensure that students are engaged meaningfully and are in a state of well-being. However, in the present scenario, students at colleges and universities have started to feel alienated from the campus life. Research shows that alienation levels are rising among the youth. Factors like stress, coping mechanism, restrictive parental behavior, peer pressure, academic performance, and organizational culture have an impact on alienation among the students. This study attempts to understand the relationship between student alienation and organizational culture in an educational institution. The study employed a descriptive correlational design and collected data from 600 under graduate students studying in a university. The study used student alienation scale and organizational culture assessment instrument to collect the survey data. Study revealed that there is a negative correlation between student alienation and organizational culture. There were 30% variation in student alienation is explained by different types of organizational culture. Clan culture reduces student alienation compared to hierarchy culture. The researchers urge for further research to identify ideal organizational cultures that can promote student engagement and student well-being. 2021, Institute of Advanced Engineering and Science.

Optimization Based Rice Leaf Disease Classification in Federated Learning
Numerous farmers worldwide are impacted by diseases connected to rice leaves that frequently endanger the sustainability of the rice industry. Diseases that affect the leaves of rice plants severely limit their ability to produce rice, and they are typically brought on by bacteria, viruses, or fungi. This paper proposes an innovative classification scheme for rice leaf diseases based on Federated Learning (FL). Here, FL framework comprises two entities, namely nodes and servers. Every node does initial local training using local data. Moreover, produced local model is then updated on server. Model aggregation is done at the server since several nodes update their local models and send them to it. The nodes download the global model that server has generated as a result. The nodes update their training using transferred global model and local model. The following series of actions are taken in the training model. The input image is mainly obtained from a database and pre-processed with a Kalman filter to eliminate noise. Then, numerous operations for data augmentation are applied. In addition, feature extraction is done and generated features are used in LeNet for rice leaf diseases classification. LeNet is trained using the Spotted Hyena Archimedes Optimizer (SHAO). The developed method shows better precision of 91.3%, recall of 92.2%, f-measure of 91.7%, loss function of 3.3%, Mean Square Error (MSE) of 7.3%, and Root MSE of 27.1%.

Cognitive Engagement Scale (CES) in an Online Environment: Construction and Validation
Researchers have demonstrated linkages between active engagement of students with learning material and greater learning gains. Cognitive engagement is a significant component of educational experience. Understanding the challenges associated with cognitive engagement and measuring cognitive engagement in a MOOC environment is challenging. It is the need of the hour with online learning being equivalent to classroom learning in todays dynamic academic environment. The present study aims to construct cognitive engagement scale (CES) to measure the cognitive engagement of learners who sign up for the massive open online courses (MOOC). The aim of this study is dual-fold: firstly, to conceptualize the cognitive dimension of learner engagement within MOOCs, and secondly, to construct a theoretically informed scale for assessing cognitive engagement in online environments. Study presents a detailed process of the scale development, which included item generation, item evaluation, pilot testing, testing psychometric properties of the scale, and scale refinement. The researchers crafted the initial questionnaire drawing from both existing literature and personal insights. Subject matter experts then validated the items within the questionnaire and ensured its reliability through a pilot study, where it was administered to a sample of 100 participants The final version of the scale captures the four dimensions of cognitive engagement: Passive receiving, active manipulating, constructive generating, and interactive dialoguing. The present study contributes to the growing literature on cognitive engagement and adds to the existing literature of MOOC engagement scale with focus on cognitive engagement exclusively.

Why small business owners get demotivated? Modeling unwillingness to grow using ISM approach
Purpose: Even after establishing their business successfully, many business owners get demotivated, and it leads to unwillingness to grow. This study aims to propose a comprehensive model that represents interrelationships among various personal factors affecting unwillingness to grow. Design/methodology/approach: The personal factors for unwillingness to grow were identified by extant literature, and expert interviews were conducted to establish the contextual relationships among these factors. The interrelationships among the filtered variables have been done using interpretive structural modeling (ISM) and MICMAC analysis was done to determine the importance of each factor in influencing unwillingness to grow. Findings: In total, 30 personal attributes were identified from previous literature, out of which 15 were selected for the final study. The result identifies 7 variables having a strong impact on unwillingness to grow. These attributes are absence of strong network, lack of vision, lack of proactiveness, reluctance to involve external consultants, absence of/small founding team, lack of ambition and improper attitude. Originality/value: The research attempts to create a bricolage of all the important personal factors affecting unwillingness to grow. Previous researches have used few attributes, but with the help of ISM, a graphical modeling technique, it became possible to draw interrelationship between 15 attributes. Further, with the help of MICMAC, the importance of each attribute was determined. 2024, Emerald Publishing Limited. -
