A study of risk perception of radiofrequency electromagnetic field (RF-EMF) exposure from mobile phones and base stations in India

ABSTRACT Due to the ever-increasing use of mobile communications in India, health risks associated with exposure to radiofrequency electromagnetic field (RF-EMF) transmitted by mobile phones and base stations has become the focus of research. Internationally, there have been numerous studies on RF-EMF risk perception, but this issue is scarcely addressed in India. The present study evaluates the level of risk perception of Indians associated with RF-EMF exposure from mobile phones and base stations and assesses the underlying reasons for their concerns. We conducted a qualitative study on a small group of Indians (n = 25) from varied socioeconomic backgrounds, followed by a large-scale population (n = 500) survey to identify the primary issues of concern. The results show that many participants, irrespective of their social group, have a positive attitude towards mobile phones and are willing to accept the risks of using them, but are against the installation of base stations. Our study confirms that lack of knowledge about mobile communications technology, health concerns about mobile phones and base stations, community concern regarding base station deployment and media influence have a significant impact on risk perception among Indians. Carefully planned communication techniques are required to decrease risk perceptions and increase acceptance of mobile communications infrastructure.
Rhetorical Structures of Introduction Sections in Sinta-Indexed Journals

This discourse study examines the rhetorical structures of RA introductions in Sinta 1 indexed ELT journals by implementing the Swales’ (2004) CARS model as the framework for analysis. A corpus consisting of 36 RA introductions was randomly collected from three SINTA 1 indexed journals, namely TEFLIN, SiELE, and IJAL, in 2019-2021. The analysis was done by using top-down analysis. The findings of the study indicated that all three moves, i.e., Move 1 Establishing a territory, Move 2 Establishing a niche, and Move 3 Presenting the present work, appeared in the introduction section across three journals. Although not all authors presented the moves and steps in appropriate sequences, the structures of moves and steps found in the corpus data were based on Swales’ CARS model. It is highly suggested that EFL students follow the Swales’ CARS model in writing an introduction.
Factors Affecting the Knowledge and Motivation of Health Cadres in Stunting Prevention Among Children in Indonesia

Purpose Stunting is a public health problem in Indonesia with a relatively high incidence, thereby making its prevention a priority for the Indonesian government. It potentially causes short and long effects on the quality of human resources as well as the productivity of stunted children when they grow up. Therefore, prevention and early detection efforts are needed by health professionals and cadres. Earlier studies have identified complexities associated with the determinant factors of stunting. This study aims to examine the association between sociodemographic factors as well as the knowledge and motivation of health cadres in stunting prevention in West Java. Methods A correlational study with a cross-sectional approach was conducted on health cadres samples from 8 districts/cities in West Java Province namely Karawang, Tasikmalaya, Garut, Bandung, Subang, Sukabumi, Cianjur, and West Bandung. A total of 363 health cadres participated and the sampling technique used is the stratified method. The data were collected using a questionnaire developed specifically for this study and were analyzed using a correlation with chi-square test and presented in the form of a frequency distribution. Results The results showed the majority of health cadres namely 81.27% had good knowledge, which was significantly influenced by education level and marital status with a P-value <0.05. Meanwhile, approximately half of the respondents had moderate motivation with 47.66%, while one-third or 39.12% had high motivation. This motivation was significantly influenced by education level, marital status, and age with p <0.05. Conclusion Based on the results, it was concluded that the roles and functions of health cadres need to be improved in the prevention and early detection of stunting in West Java by providing continuous guidance, stunting prevention training, and award presentations.
PVR (CD155) Expression as a Potential Prognostic Marker in Multiple Myeloma

Poliovirus receptor (PVR, CD155) is upregulated during tumor progression, and PVR expression is associated with poor prognosis in cancer patients; however, prognostic implications for PVR in multiple myeloma (MM) have not been investigated. PVR plays an immunomodulatory role by interacting with CD226, CD96, and TIGIT. TIGIT is a checkpoint inhibitory receptor that can limit adaptive and innate immunity, and it binds to PVR with the highest affinity. We used immunohistochemistry, ELISA, qPCR, and flow cytometry to investigate the role of PVR in MM. PVR was highly expressed in patients with MM, and membrane PVR expression showed a significant correlation with soluble PVR levels. PVR expression was significantly associated with the Revised-International Staging System stage, presence of extramedullary plasmacytoma and bone lesion, percentage of bone marrow plasma cells (BMPCs), and β2-microglobulin levels, suggesting a possible role in advanced stages and metastasis. Furthermore, TIGIT expression was significantly correlated with the percentage of BMPCs. Patients with high PVR expression had significantly shorter overall and progression-free survival, and PVR expression was identified as an independent prognostic factor for poor MM survival. These findings indicate that PVR expression is associated with MM stage and poor prognosis, and is a potential prognostic marker for MM.
Designing ‘Authenticity’ in Digital Learning Environments

This article reports on a study into the integrative use of social media tools to create an ‘authentic digital learning environment’ for undergraduate literature teaching at City University of Hong Kong. An authentic digital learning environment is one that is created—rather than adopted or adapted—by student cohorts. The findings of the study suggest that the use of digital media in the classroom can create higher levels of student engagement, but only when it is embedded systematically in module design. This article outlines the rationale for moving to a digital learning environment composed of social tools, thereby situating learning in a context that is more authentic to students while seamlessly integrating digital literacy education into traditional subject areas
Does financial reporting quality affect the investment efficiency of listed
textile sector firms in Pakistan? A myth or reality

The study investigates the relationship between financial reporting quality and investment efficiency in Textile sector firms listed on the Pakistan Stock Exchange, due to the reason of being the highest-ranked sector with a maximum number of listed firms in Pakistan. We use financial reporting quality as an independent variable, investment efficiency as a dependent variable, and the firm’s annual cash, assets tangibility, and return on assets as control variables. We analyse 100 randomly selected firms for the period 2005 to 2019. The study applies various estimators, namely Pooled OLS, Fixed Effects, and Random Effects to identify which model better predicts results. The results demonstrate that firm’s financial reporting quality and ROA have a positive significant effect on the investment efficiency of these selected firms in all three models, but Random Effects Model estimates better coefficients than the counterparts. While the firm’s annual cash predicts a positive insignificant effect on the investment efficiency in the case of all competing models. Asset’s tangibility shows a negative significant effect on the investment efficiency of these firms. The study will help the academicians in their researches, decision-makers, and top management of this particular manufacturing sector in getting insight into framing and formulating their financial strategies.
Control-Theoretic Models of Feedforward in Manual Control

Understanding how humans control a vehicle (cars, aircraft, bicycles, etc.) enables engineers to design faster, safer, more comfortable, more energy efficient, more versatile, and thus better vehicles. In a typical control task, the Human Controller (HC) gives control inputs to a vehicle such that it follows a particular reference path (e.g., the road) accurately. The HC is simultaneously required to attenuate the effect of disturbances (e.g., turbulence) perturbing the intended path of the vehicle. To do so, the HC can use a control organization that resembles a closed-loop feedback controller, a feedforward controller, or a combination of both. Previous research has shown that a purely closed-loop feedback control organization is observed only in specific control tasks, that do not resemble realistic control tasks, in which the information presented to the human is very limited. In realistic tasks, a feedforward control strategy is to be expected; yet, almost all previously available HC models describe the human as a pure feedback controller lacking the important feedforward response. Therefore, the goal of the research described in this thesis was to obtain a fundamental understanding of feedforward in human manual control. First, a novel system identification method was developed, which was necessary to identify human control dynamics in control tasks involving realistic reference signals. Second, the novel identification method was used to investigate three important aspects of feedforward through human-in-the-loop experiments which resulted in a control-theoretical model of feedforward in manual control. The central element of the feedforward model is the inverse of the vehicle dynamics, equal to the theoretically ideal feedforward dynamics. However, it was also found that the HC is not able to apply a feedforward response with these ideal dynamics, and that limitations in the perception, cognition, and action loop need to be modeled by additional model elements: a gain, a time delay, and a low-pass filter. Overall, the thesis demonstrated that feedforward is indeed an essential part of human manual control behavior and should be accounted for in many human-machine applications.
Investigation of Concrete Shrinkage Reducing Additives

This paper analyzes the efficiency of shrinkage reducing additives for the shrinkage deformations of ordinary Portland cement (OPC) concrete and its mechanical properties. OPC concrete was modified with an organic compound-based shrinkage reducing additive (SRA), quicklime, polypropylene fiber, and hemp fiber. It was found that a combination of 2.5% quicklime and 1.5% SRA led to the highest reduction in shrinkage deformations in concrete, and the values of shrinkage reached up to 40.0%. On the contrary, compositions with 1.5% SRA were found to have a significant reduction in compressive strength after 100 freeze-thaw cycles. Hemp fiber did not show a significant shrinkage reduction, but it is an environmentally friendly additive, which can improve OPC concrete flexural strength. Polypropylene fiber can be used in conjunction with shrinkage reducing additives to improve other mechanical properties of concrete. It was observed that 3.0 kg/m3 of polypropylene fiber in concrete could increase flexural strength by 11.7%. Moreover, before degradation, concrete with polypropylene fiber shows high fracture energy and decent residual strength of 1.9 MPa when a 3.5 mm crack appears. The tests showed a compressive strength decrease in all compositions with shrinkage reducing additives and its combinations after 28 days of hardening.
Post-traumatic headache: Pathophysiology and management - A review

Background Post-traumatic headache (PTH) is a common secondary headache due to traumatic brain injury. In the past, significant research has been conducted to understand the pathophysiology and treatment options for PTH. However, PTH still lacks evidence-based treatment, and most of the management depends on the primary phenotype observed in the patient. Objective The main objective of this review is to provide a single reference that covers the current understanding of the pathophysiology and the treatment options available for PTH. Methods A detailed literature search on PubMed was performed, and a narrative review was prepared. Results The pathophysiology of PTH is multifactorial. Acute PTH may be attributed to increased peripheral pain sensitization with impaired pain inhibiting pathways. Chronic or persistent PTH may be due to a chronic inflammatory response and peripheral as well as central sensitization. The mechanism responsible for the transition of acute to persistent PTH is unknown. The migraine-like phenotype is reported to be the most prevalent headache type seen in PTH. New targets for preventive treatment have been identified in recent years, such as neuropeptides like calcitonin-gene-related peptide (CGRP), nitric oxide, and glutamate. The preventive pharmacological and non-pharmacological strategies employed for migraine (e.g. anti-CGRP monoclonal antibodies, onabotulinumtoxinA, physical therapy, cognitive and behavioral treatment, and neurostimulation techniques) have shown in preliminary studies that they are potentially efficacious, but large, randomized, double blind, placebo controlled trials are needed to further establish these as treatment options for PTH. Conclusions The lack of evidence-based treatment for PTH has created a need for future large trials to confirm the safety and efficacy of the currently employed treatments.
Circulating Monocyte Subsets and Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR), as an alternative to open heart surgery, has revolutionized the treatment of severe aortic valve stenosis (AVS), the most common valvular disorder in the elderly. AVS is now considered a form of atherosclerosis and, like the latter, partly of inflammatory origin. Patients with high-grade AVS have a highly disturbed blood flow associated with high levels of shear stress. The immediate reopening of the valve during TAVR leads to a sudden restoration of a normal blood flow hemodynamic. Despite its good prognosis for patients, TAVR remains associated with bleeding or thrombotic postprocedural complications, involving mechanisms that are still poorly understood. Many studies report the close link between blood coagulation and inflammation, termed thromboinflammation, including monocytes as a major actor. The TAVR procedure represents a unique opportunity to study the influence of shear stress on human monocytes, key mediators of inflammation and hemostasis processes. The purpose of this study was to conduct a review of the literature to provide a comprehensive overview of the impact of TAVR on monocyte phenotype and subset repartition and the association of these parameters with the clinical outcomes of patients with severe AVS who underwent TAVR.
Role of Propofol with total intravenous anesthesia in intra-abdominal surgeries

The analgesic properties of propofol may make it a useful opioid-sparing analgesic adjunct for colorectal surgery in the context of a multimodal analgesic regime. Propofol is a commonly used intravenous anesthetic drug. Total intravenous anesthesia (TIVA) with propofol can be used for both induction and maintenance of general anesthesia. Propofol has been associated with pain relief both in animal studies and in human healthy volunteer studiesPostoperative pain can be severe post multiple abdominal surgeries due to the upper abdominal incision and pain management can be difficult for this group of patients,therefore total intravenous anaesthesia is a technique involving infusion and maintenance of anaesthetic state with intravenous drugs alone. But no agent has all the characteristics of ideal TIVA agent. Propofol has three important characteristics of ideal TIVA agent, i.e. rapid induction, rapid metabolism and rapid recovery. In this communication we studied the characteristics of propofol in total intravenous anaesthesia in various intra-abdominal surgeries. Vital signs, including blood pressure, oxygen saturation (SpO2), heart rate, and body temperature, were monitored in the post anesthesia care unit (PACU).
Electrocatalytic Performance of Thiacalix[4]arene-based Co(II) Complex in Hydrogen Evolution Reaction

The generic electron-rich thiacalix[4]arene bearing sulfur and oxygen coordinating donor atoms in the lower rim is underestimated as a pre-catalyst for the Hydrogen Evolution Reaction (HER). In addition, cobalt is a promising metal ion for many electrocatalytic applications, including HER. Herein, we report the electrocatalytic activity of a cobalt(II) compound based on thicalix[4]arene that was characterized by cyclic voltammetry (CV). The CV using the glassy carbon as a working electrode versus Ag/AgCl, show two reduction peaks at -0.582 V and -1.270 V for the two redox couples Co 2+ /Co + and Co + /Co, respectively. The two-electron proton reduction into hydrogen in the presence of the catalyst and 5 equivalents (12.5 mM) of acetic acid show a noticeable shift of about 780 mV compared to the catalyst-free reaction and 200 mV compared to the second wave observed for the acid-free solution. Moreover, a maximum anodic peak current of 32 µA was observed upon adding 30 equivalents (75 mM) of acetic acid.
Decision Tree Model for Educational Services Predicting Children's Academic Performance by Income Group

Background and objective: This study used the decision tree analysis among data mining techniques to determine whether children's academic performance can be classified and predicted by income group based on factors of educational services.Methods: For empirical analysis, data from the 10th Panel Study on Korean Children collected in 2017 was utilized. A F test was conducted to analyze the differences in variables by income group, and a decision tree analysis was conducted on the cost and time of private education services utilized by children to predict their academic performance by income group.Results: First, as a result of analyzing the research variables by income group, there was a significant difference in institute time, community center time, institute cost, lesson cost, after-school cost, and culture center cost. Second, as a result of the decision tree analysis that predicts children's academic performance by income group, it was found that for children in the low-income group, institute cost, institute time, visiting cost, and after-school time were important variables that predict their academic performance. For children in the middle-income group, institute cost, after-school time, and after-school cost were important variables for predicting academic performance. For children in the high-income group, the important variables were institute time, institute cost, after-school time, and after-school cost.Conclusion: There was no significant difference in children's academic performance in the earlier grades of elementary school, but there was a significant difference in the private education service they utilized, which may affect future income gaps as well as education gaps. This suggested the need to diversify and improve the quality of public education services as a countermeasure for the fact that parental income will cause an academic gap among children through private education.
Too Many Treats or Not Enough to Eat? The Impact of Caregiving Grandparents on Child Food Security and Nutrition

With the number of grandparent-headed households on the rise, the influence of grandparents needs to be considered in the fight to reduce child obesity. The current study investigated the influence of caregiver type (i.e., grandparents only, parents only, or multi-generational households) on children’s nutrition, food security, and BMI. This was a cross-sectional, secondary analysis based on the 2009–2010 wave of the Health Behavior in School-Aged Children (HBSC) survey in collaboration with the World Health Organization. This sample included 12,181 students from 10,837 families with only parents present in the household, 238 with only grandparents present, and 1106 multi-generational families. One-way analyses of covariance (ANCOVAs) were conducted using caregiver type as the independent variable, controlling for SES, on items assessing frequency of breakfast consumption, nutrition intake, hunger, snacking frequency and location, and BMI. Children reported more unhealthy snacking in households with only grandparents. Hunger was reported more often in multi-generational households. These results support that caregiver type, especially caregiving grandparents, is a significant predictor of children’s BMI, nutrition, and food security. Tailoring nutrition education to the needs of grandparents could help both the health of grandparents and the reduction of child obesity.
Preservation and Completeness of Fluvial Meandering Deposits Influenced by Channel Motions and Overbank Sedimentation

Assessing the contribution of geomorphic processes to the (non‐)preservation of sedimentary deposits is necessary to account for potential bias in measured accumulation rates in the stratigraphic record. In this study, a series of numerical simulations of fluvial meandering successions is performed using FLUMY, a model of channel motions and sedimentary facies deposition. We develop tools to measure non‐deposition (stasis S) and reworking (R) of previously deposited sediment between iterations, which are both generators of hiatuses in the sedimentary record. We then compare S and R with measurements of accumulation rates and completeness (C). Results show that combining measurements of both topographic and facies changes allows for a better record of surface evolution than measuring topographies only. Accumulation rate dependence on measurement time span allows distinguishing between two regimes. The first one (anti‐persistent) is characteristic of channel avulsion and compensational stacking until the whole domain is visited by overbank deposition, corresponding to the visitation timescale Tv. In the second regime (persistent), reworking by channel migration is the remaining active process until the whole system has aggraded one channel depth, corresponding to the compensation timescale Tc. Based on these results, we propose a new simple formulation based on stasis and reworking to estimate average completeness.
