Calmodulin (CaM) and calmodulin-like (CML) proteins are major Ca2+ sensors involved in the regulation of plant development and stress responses by converting Ca2+ signals into appropriate cellular responses. However, characterization and expression analyses of CaM/CML genes in the precious species, Phoebe bournei, remain limited. In this study, five PbCaM and sixty PbCML genes were identified that only had EF-hand motifs with no other functional domains. The phylogenetic tree was clustered into 11 subgroups, including a unique clade of PbCaMs. The PbCaMs were intron-rich with four EF-hand motifs, whereas PbCMLs had two to four EF-hands and were mostly intronless. PbCaMs/CMLs were unevenly distributed across the 12 chromosomes of P. bournei and underwent purifying selection. Fragment duplication was the main driving force for the evolution of the PbCaM/CML gene family. Cis-acting element analysis indicated that PbCaMs/CMLs might be related to hormones, growth and development, and stress response. Expression analysis showed that PbCaMs were generally highly expressed in five different tissues and under drought stress, whereas PbCMLs showed specific expression patterns. The expression levels of 11 candidate PbCaMs/CMLs were responsive to ABA and MeJA, suggesting that these genes might act through multiple signaling pathways. The overexpression of PbCaM3/CML13 genes significantly increased the tolerance of yeast cells to drought stress. The identification and characterization of the CaM/CML gene family in P. bournei laid the foundation for future functional studies of these genes.

Published: December 2023

In this work, we investigated the MOCVD conditions to synthesize thin films with the hexagonal P63cm h-LuMnO3 phase as a potential low-band gap ferroelectric material. The main parameters investigated were the ratio of organometallic starting materials, substrate temperature, and annealing effect. Two different substrates were used in the study: fused silica (SiO2) glass and platinized silicon (Pt\Ti\SiO2\Si(100)). In order to investigate the thermodynamic stability and quality of the developed phases, a detailed analysis of the crystal structure, microstructure, morphology, and roughness of the films was performed by X-ray diffractometer, scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), Raman spectroscopy, and piezoelectric force microscopy (PFM). Molar compositions in the film within 0.93 < |Lu|/|Mn| < 1.33 were found to be suitable for obtaining a single-phase h-LuMnO3. The best films were obtained by depositions at 700 °C, followed by thermal treatments at 800 °C for long periods of up to 12 h. These films exhibited a highly crystalline hexagonal single phase with a relatively narrow direct band gap, around 1.5 eV, which is within the expected values for the h-LuMnO3 system.

Contexts of Extraordinary Parental Involvement in Children’s Education During the First Wave of COVID-19: A Case Study of a Public Elementary School in Poland
Authors: Wiatr Marta 
Published: December 2023

Objectives of the research: The purpose of the study was to learn about parents’ experiences of participating in their children’s remote education during the first wave of the COVID-19 pandemic. The question posed in this article is about the circumstances under which parents took over tasks previously perceived as a teacher’s job.
Research methods: The participatory, qualitative case study utilized data from the open-ended questions of an electronic survey to which 104 parents (from a public elementary school in a metropolitan area) responded, as well as data from the school’s electronic register. The qualitative analysis employed strategies of constructivist grounded theory.
Brief description of the context of the problem: While national and international studies have shown that parents played a critical role in the challenging and stressful home-based education of their children during the COVID-19 pandemic, no research has explained how parents became this vital link of education. The aim of this article is to fill this gap.
Research findings: The study revealed two interrelated contextual factors that led to parents’ activation in their children’s “schooling from home”: 1) technical/administrative, related to having inadequate tools for distance education and 2) pedagogical/didactic, related to the prevailing concepts of teaching and learning being anchored in the behavioral-transmission paradigm.
Conclusions and/or recommendations: The results apply primarily to the school under study and represent an intrinsic case study. However, it is reasonable to assume that the events, phenomena, and processes identified in the study may serve to explain phenomena in other schools that have organized distance education similarly. The cautious recommendation, aiming to safeguard family resources (thereby protecting equal opportunities for all children to learn) in times of crisis, is to transform the pedagogical underpinnings that shape today’s educational practices from behaviorist to constructivist. However, this requires further research.
