ASSESSMENT OF PSYCHOLOGICAL DISTRESS AMONG PRIMARY SCHOOL TEACHERS IN KEDAH, MALAYSIA

Background: Teaching is a challenging profession, where the educators are constantly monitoring complex classroom situations to maximize the learning opportunities for their students. Majority of the teachers in Malaysia reported with an increasing prevalence of depression, anxiety, and stress during the pandemic. Hence, the present study aimed to assess the psychological distress among primary school teachers in Kedah, Malaysia using the GHQ-12 questionnaire. Methods: This cross-sectional study involved 217 participants from four primary schools in the district of Kulim, Kedah. The respondents were selected through convenience sampling, and their psychological distress was measured by administering the GHQ-12 scale. Results: Descriptive statistics revealed that majority were female teachers (n=134, 61.8%), in comparison to males (n=83, 38.2%). The ethnic groups comprised of Chinese (39.2%), Malay (32.3%), and Indians (28.6%); most of them aged between 31-35 years (n=120, 55.2%), and from urban area (n=144, 66.3%). Reliability analysis showed 0.781, which suggests that the GHQ-12 scale employed in Turkish Journal of Physiotherapy and Rehabilitation; 32(3) ISSN 2651-4451 | e-ISSN 2651-446X www.turkjphysiotherrehabil. org 25157 this study is highly reliable. Using a cut-off point of 12 and above, the study findings indicated that majority of the respondents (73.7%) have been experiencing psychological distress. Significant differences in psychological distress were observed between teachers from urban and rural area (27.64 and 24.78; p<0.001). Contrary to expectation, no significant gender (p=0.544) and ethnic (p=0.866) differences were found related to psychological distress. Conclusion: Since, teacher’s mental health is a critical prerequisite to produce an effective learning environment for pupils, further investigation is strongly recommended to comprehend the phenomenon that could shed more light on the prevention and intervention strategies.
Superpoint Network for Point Cloud Oversegmentation

Superpoints are formed by grouping similar points with local geometric structures, which can effectively reduce the number of primitives of point clouds for subsequent point cloud processing. Existing superpoint methods mainly focus on employing clustering or graph partition to generate superpoints with handcrafted or learned features. Nonetheless, these methods cannot learn superpoints of point clouds with an end-to-end network. In this paper, we develop a new deep iterative clustering network to directly generate superpoints from irregular 3D point clouds in an end-to-end manner. Specifically, in our clustering network, we first jointly learn a soft point-superpoint association map from the coordinate and feature spaces of point clouds, where each point is assigned to the superpoint with a learned weight. Furthermore, we then iteratively update the association map and superpoint centers so that we can more accurately group the points into the corresponding superpoints with locally similar geometric structures. Finally, by predicting the pseudo labels of the superpoint centers, we formulate a label consistency loss on the points and superpoint centers to train the network. Extensive experiments on various datasets indicate that our method not only achieves the state-of-the-art on superpoint generation but also improves the performance of point cloud semantic segmentation.

Immigrant peers in the class: responses among natives and the effects on long-run revealed preferences. IFAU working paper 2021:16

We investigate whether exposure to immigrant peers at school affects natives’ future interactions with ethnic minorities. Identification is based on variation in immigrant exposure across cohorts within school catchment areas in Sweden. We document that natives respond to immigrants by changing school and develop an IV strategy that accounts for such endogenous responses. Our results show that minority exposure at the extensive margin increases the probability that natives form inter-ethnic romantic partnerships, which is suggestive of altered preferences for interacting with immigrants. We also find that minority exposure affects women’s educational choices and family formation decisions in a family-oriented direction.
Exploring the role of milk yield in the first week of lactation on the association between hyperketonemia and reproductive performance in dairy cattle

Graphical Abstract Summary: Hyperketonemia (HYK) is a metabolic disorder in dairy cattle related to difficulties during the transition period and associated with suboptimal reproductive performance. Studies have proposed the monitoring of the transition period based on early-lactation milk yield. Therefore, our objective was to explore the role of milk yield during the first week of lactation on the relationship between HYK and reproductive performance. Cows (N = 2,091) were tested for HYK (blood BHB ≥1.2 mmol/L), between 3 and 10 DIM. First-week milk yield was classified into 3 levels according to parity and herd. Reproductive performance was assessed until 150 DIM. After adjustments, we found no evidence to support an association between HYK and reproduction. However, models stratified by early milk yield showed that HYK was associated with lower risk of pregnancy among low-yielding cows. Results suggests that early milk yield plays a role in the association of hyperketonemia with reproduction.
Molecular Docking Analysis of Ficus religiosa Active Compound with Anti-Inflammatory Activity by Targeting Tumour Necrosis Factor Alpha and Vascular Endothelial Growth Factor Receptor in Diabetic Wound Healing

BACKGROUND: Diabetes mellitus contributes to the delayed healing of wounds causes disturbance of inflammatory cytokine. Tumour necrosis factor alpha (TNF-alpha) and Vascular Endothelial Growth Factor Receptor (VEGFR) both have a role in the persistent inflammation associated with diabetic wounds. Ficus religiosa has developed a reputation as a traditional wound healer among some java people in Indonesia. AIM: Our study aims to discover the molecular interaction between the active constituents of F. religiosa with TNF-alpha and VEGFR. MATERIALS AND METHODS: This research was conducted in computerized molecular docking using Protein database, Pymol, Discovery studio, and Pyrex software. A thorough literature search was conducted to identify the potential compound and molecular target for diabetic wounds. Analysis of its anti-inflammatory properties was also carried out using a passonline webserver. Pharmacokinetic analysis was performed using the Lipinski Rule of Five websites and the PreADMET website. RESULTS: Each of the study’s active compounds has a good pharmacokinetic profile. The predictions of the compound’s structure indicate that it has a strong anti-inflammatory impact. Lupenyl acetate and Lanosterol bind more strongly to the TNF-alpha than the natural ligand, but Piperine binds more strongly to VEGFR. CONCLUSIONS: Lupenyl acetate, Lanosterol, and Piperine compounds have anti-inflammatory effects through inhibition of TNF-alpha and VEGFR. In addition, this compound has potential to become a drug because it has good pharmacokinetics. Future studies are required to determine the effectiveness and toxicity of Lupenyl acetate, Lanosterol, and Piperine as potential treatment in diabetic wounds.
Nitrogen and phosphorus supply strongly reduced the control efficacy of maize against sunflower broomrape

ABSTRACT Heavy infestation by the root parasitic sunflower broomrape over wide regions constitutes a major biological constraint to sunflower production. The use of maize as a trap crop to induce sunflower broomrape germination is considered a cost-effective method for controlling sunflower broomrape. This study was designed to examine the activity of maize to induce sunflower broomrape seeds germination under varying levels of nitrogen (N) and phosphorus (P) fertilization. Orthogonal experiments were conducted during two cropping seasons with four maize cultivars under four levels of N and P application. A significant reduction in sunflower broomrape germination induced by maize root and rhizosphere soil extracts upon N and P application was observed in both 2014 and 2015, with P having the strongest effect on the broomrape germination inducing activity of maize root extracts. Structural equation modelling analysis revealed that N and P supplementation not only directly affected the germination-inducing capacity towards sunflower broomrape of maize root extracts but also had an indirect effect through the impact on abscisic acid contents. This study may contribute to a better understanding of the connection between soil fertility and the production and release of germination stimulants in maize and that can lead to improved control strategies.
Oleanolic acid reduces oxidative stress and neuronal apoptosis after experimental subarachnoid hemorrhage by regulating Nrf2/HO‐1 pathway

Oxidative stress is an early major pathological feature after subarachnoid hemorrhage (SAH) and involves in the development of acute brain injury, neuronal apoptosis and cerebral vasospasm following SAH. Antioxidant stress is an effective way to improve the prognosis of SAH. Oleanolic acid is a widely used triterpenoid from plants, which has strong antioxidant activities, hepatoprotective, anti‐inflammatory and anti‐cancer activities. However, whether oleanolic acid exerts its anti‐oxidant effect after SAH and the underlying mechanisms involved in it is unclear. In current study, the SAH model was established on Sprague Dawley rats using a standard intravascular puncture model. We found OA treatment significantly reduced malondialdehyde levels, and increased the levels of superoxide dismutase, catalase and GSH‐Px after SAH, and reduced many EBI‐related indicators, including brain edema, BBB disruption, SAH grades, and neurological score. In addition, the activation of Nrf2/HO‐1 pathway after SAH was also detected. And by using Nrf2 siRNA intracerebroventricular injections, apoptosis related factors downstream of Nrf2/HO‐1 pathway were detected. By TUNEL staining, OA treatment obviously reduced neuronal apoptosis. Therefore, we suggest that OA could alleviate oxidative stress and reduce neuronal apoptosis through activating Nrf 2/HO‐1 pathway.
An application of the transtheoretical model to climate change prevention: Validation of the climate change stages of change questionnaire in middle school students and their schoolteachers

Abstract Certain behaviors, especially when adopted by a majority, can help limit the magnitude of climate change. In this cross-sectional study, the stages of change from the Transtheoretical Model (TTM) are applied to environmentally-significant behavior. We develop and test a new scale – the Climate Change Stages of Change Questionnaire (CCSOCQ) – for measuring five discrete stages involved in changing behavior to address climate change (precontemplation, contemplation, preparation, action, and maintenance). In total, 3,469 middle-school students (Mage = 13.4) and 347 schoolteachers completed the CCSOCQ and a measure of engagement with sustainable development. Analyses indicated the CCSOCQ captured the five stages outlined by the TTM and had adequate psychometric properties. Further supporting predictions of the TTM, engagement with sustainable development was lowest in the precontemplation stage and highest in the action stage. We conclude the TTM has potential for describing how and why people alter their behavior to address climate change.

OXA-48-positive carbapenem-resistant Enterobacteriaceae in a farrow-to-finish pig farm: First report in Thailand

Carbapenem-resistant Enterobacteriaceae (CRE) have emerged as an urgent threat to public health. This study aimed to determine the occurrence of CRE and the carbapenemase genes in a farrow-to-finish pig farm, and to investigate carriage proportion and maintenance of CRE during the pig production cycle. We conducted a cross-sectional study by collecting 200 rectal swabs from healthy pigs of 5 groups: gilts, sows, piglets, weaners, and fatteners. In the longitudinal study, 20 healthy pigs were followed from 2 to 26 weeks old, and rectal swabs were collected from each pig for 5 times. Samples were screened for CRE using MacConkey agar supplemented with meropenem at 0.5 µg/mL. Identification and antimicrobial susceptibility pattern of the recovered isolates were determined using an automated system. PCR was used to detect carbapenemase genes. The occurrence of Enterobacteriaceae isolates with the carbapenem resistant phenotype and/or harboring the blaOXA-48 gene was 3% (6/200) in the cross-sectional study. Groups of sows and piglets had the same occurrence rate at 5% (2/40), while weaner and fattener groups had 2.5% (1/40). In the longitudinal study, CRE were not detected in pigs at an early age; however, two isolates were detected at the age of finishing. This study is the first report of Enterobacteriaceae with a carbapenem resistant phenotype and/or carrying blaOXA-48 gene in pigs in Thailand. Finding CRE in pigs at all age categories including finisher in the study farm underscores the need for active monitoring and surveillance studies to determine the occurrence of CRE in pig farms in Thailand.
Investor’s Reaction to Corporate Action Announcement: New Product and System and Technology Innovation

This study aims to know how investors react to corporate action announcements and to which categories that investors react more positively to. This study differs from previous studies because we use three different event windows to calculate CAR, which are [+2, 0, -2], [+1, 0, +1], [-1, 0]. We also use firm size, market share, and market capitalization as control variables. Based on 201 samples in the period of 2020 by auto manufacturing firms in East Asia, we find that there is a significant difference of CAR between the firms that do and don't do corporate actions. Based on 148 corporate action announcements, we find that the new product category is responded more positively by investors than the system & technology innovation category. Besides that, we also find that firm size significantly affects investor’s response, where large firms get more positive response from investors than small firms. The larger the size of the firm means that the firm has more resources and experiences, which give large firms more opportunities to successfully do corporate action. That reason makes investors interested to invest in large firms because they believe that large firms have better business prospects in the future. This study examines investor’s response to corporate action announcements only in the automotive sector. Other sectors’ results may differ from this study; therefore, future research has the opportunity to follow up on these issues.
Developing Key Performance Indicators for Public-Private Partnership Projects: Questionnaire Survey and Analysis

AbstractPublic-private partnerships (PPPs) are increasing in popularity. Major challenges in the development of PPPs have resulted from the global financial crisis. However, with respect to their monetary value, PPPs are still an attractive option for public sector projects. Performance management and measurement, in which Key Performance Indicators (KPIs) are the core elements, viewed as effective methods to help PPPs deliver value for money. This article describes in greater detail a KPI conceptual model composed of 5 performance packages and 48 indicators developed by the authors in previous studies. A structured questionnaire survey explored PPP stakeholders perceptions of 48 project performance indicators (PIs) to identify actual KPIs for performance management and measurement in PPPs. Although the survey results show that all PIs are important, performance packages contribute differently to the overall project performance. A confirmatory factor analysis (CFA) was used to test whether the proposed co.
Synthesis of Carbon Nanotubes via Liquid Injection Chemical Vapour Deposition as a Vector for the Chemical Recycling of Waste Composite Carbon Sources

For every three people on the planet there is approximately two Tonne (Te) of available plastic waste. We show that carbon recovery from polystyrene (PS) plastic is enhanced by the co-addition to solvents to grow carbon nanotubes (CNTs) by liquid injection chemical vapour deposition. Polystyrene was loaded up to 4 wt% in toluene and heated to 780 °C in the presence of a ferrocene catalyst and a hydrogen/argon carrier gas in a 1:19 ratio. High resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and Raman spectroscopy were used to identify multi-walled carbon nanotubes (MWCNTs). The PS addition in the range from 0 to 4 wt% showed improved quality and CNT homogeneity; Raman “Graphitic/Defective” (G/D) values increased from 1.9 to 2.3; mean CNT diameters increased from 43.0 to 49.2 nm; and maximum CNT yield increased from 11.3% to 14.2%. Since both the CNT diameters and the percentage yield increased with respect to polystyrene addition, we conclude that carbon from the PS contributes to the carbon within the MWCNTs. The electrical contact resistance of acid washed Bucky papers produced from each loading, ranged from 2.2 to 4.4 Ohm, with no direct correlation to PS loading. Due to this narrow range, the materials with different loading were mixed to create six wires of an Ethernet cable and tested using iPerf to give uplink and downlink speeds of ~99.5 Mbps, comparable to Cu wire of identical dimension (~99.5 Mbps). The lifecycle assessment (LCA) of CNT wire production was compared to copper wire production for the use case in a Boeing 747-400 over the lifespan of the craft. Due to their lightweight nature the CNT wires decreased the CO2 footprint by 21 kTonne (kTe) over the aircraft lifespan.

Contribution of GEANT4 to the determination of sensitive volumes in case of high-integrated RAMs

This paper deals with the use of short range beams in order to measure the sensitive thickness of devices. In the case of a Hitachi 4-Mbit SRAM, /spl sigma/(E) measurements have been compared to GEANT 4 calculations, taking into account the effects of the overlayers. The analysis of the experimental data at two bias levels has pointed out that /spl sigma/(E) is directly correlated with the energy deposited in SV for low ranges, on the other hand charge collection mechanisms have a strong impact for longer ranges.
Developments in Quality of Work-Life Research and Directions for Future Research

Objective of this paper was to observe trends and developments in quality of work-life research throughout the decades. Previous researchers mostly focused on systematic and general literature reviews. In this paper bibliometric analysis and systematic literature review were combined to observe the trends and developments in quality of work-life research. An electronic Scopus database search initially produced of 867 documents on quality of work-life. Further purposive screening reduced the documents to 752 altogether. Furthermore, a detailed literature review of top 10 most cited publications throughout the decades of quality of work-life research was conducted, to explore construct development, antecedents, and outcomes of quality of work-life. Bibliometric analysis revealed that most of the research was produced from United States, and in areas of business, management, and accounting. Literature review revealed that from 1970s to 1980s, the focus of quality of work-life research was mainly on construct development. From 1990s onward, researchers mostly focused on identifying antecedents and outcomes of quality of work-life at organizational and employee level. Findings of this research suggests various employee and organizational level factors which have been neglected by most influential studies of quality of work-life throughout the decades. Future researchers should focus on these factors to motivate government and organizations to incorporate these factors in their system, and to support the quality of work-life research.
