Conspiracy mentality: How it relates to populism, relative deprivation, mistrust of expertise and voting behaviour
Authors: Loziak Alexander , Havrillová Dominika
Published: February 2024

Background and research aims. Considering the high prevalence of conspiracy theories and misinformation, there is an urgent need to explain the tendency to adopt a conspiracy mentality and identify behavioural (including voting) outcomes of a high conspiracy mentality. The aims of the present paper are 1) the examination of populist attitudes dimensions, relative deprivation and mistrust of expertise as predictors of conspiracy mentality and 2) proposal of comprehensive models, that combine predictors of conspiracy mentality and its voting consequences. Methodology. Studies utilised OSL regression and structural equation modelling. Results. The overall regression was statistically significant. It was found that dimensions of populist attitudes (anti-elitism, sovereignty), relative deprivation and mistrust of expertise were significant predictors of conspiracy mentality. In line with the second research aim, the fitness of models was confirmed and results suggest mistrust of expertise is also a significant predictor of far-right voting. Discussion. The contribution of the paper lies in connecting conspiracy mentality with not only attitudes but also with important behaviour outcome - voting behaviour. We propose future research should experimentally examine whether the reduction of some of the identified predictors could possibly lower levels of conspiracy mentality and whether this reduction translates into voting behaviour.

Humanitarian Externalisation
Authors: Owen David
Published: February 2024

Why are the reasons given in support of the declared aim of the current asylum policies in the UK, EU and USA of breaking the business model of smugglers expressed in humanitarian terms? It is, no doubt, tempting to simply dismiss this humanitarian rhetoric as hypocrisy, as the compliment that vice pays to virtue. Yet however justified that dismissal may be in particular cases, to turn away too quickly from this phenomenon would be to miss something of political significance in its form and to fail to register the historical entanglement of humanitarianism and border externalisation.

Authors: Kim Mi Hyun , Park Bu Kyung
Published: February 2024

Purpose: The purpose of this study was to develop a child abuse prevention education program for parents. Furthermore, the aim was to investigate the impact of child abuse prevention education on parents’ response to positive emotion, parenting stress, and potential for child abuse.Methods: A randomized controlled pretest posttest design was used. A total of 60 participants, who were parents with children aged 1~5 and attending 8 nurseries and kindergartens located in Daegu, were recruited. They were randomly assigned to an experimental group (n=30) and a control group (n=30). The collected data were analyzed by an independent t-test, paired t-test, and χ²-test along with descriptive statistics using IBM SPSS Statistics 25.0. Child abuse prevention education for the experimental group included four modules on child rights, understanding child abuse, proper child discipline, and positive parenting attitudes.Results: The experimental group showed a significant difference in positive rumination from the control group (t=2.15, p=.036). The experimental group reported a significant difference in dampening from the control group (t=-2.49, p=.016). Additionally, the experimental group reported a significant difference in parenting stress from the control group (t=-2.12, p=.038) and also reported significant differences in child abuse potential from the control group (t=-2.26, p=.028).Conclusion: The results of this study indicate that child abuse prevention education for parents can improve positive rumination, reduce dampening, and reduce parenting stress and child abuse potential. Therefore, this study is useful in demonstrating how parental susceptibility to child abuse can be decreased. Future studies should pursue long-term programs and counseling programs.

Published: February 2024

Stunting is a serious nutritional problem which can be seen from shorter body length or height in toddlers compared to children of the same age. The prevalence of stunting in Indonesia increased from 2010 to 2013, from 35.6% to 37.2%. The factors that influence the incidence of stunting in children are the age of the mother, the distance between pregnancies, history of maternal illness, nutritional status during pregnancy, and low birth weight. The aim of this research is to determine the factors related to the incidence of stunting in the Siulak Mukai Health Center Working Area, Kerinci Regency in 2021. This type of research is descriptive analytic with a cross sectional design. This research was carried out in April-August 2021. The population was 192 mothers of babies aged 0-2 years and a sample of 66 people was taken using Systematic Random Sampling. Data analysis consisted of univariate analysis and bivariate analysis using the chi-square statistical test. The results showed that a small proportion (19.7%) of toddlers experienced stunting, the age of the mother who was at risk was only 5 people (7.6%), less than half (21.2%) of respondents with risky pregnancy intervals, more than half (54, 5%) of respondents with a history of illness during pregnancy, less than half (24.2%) of respondents with inappropriate nutritional status during pregnancy, and only 6 respondents with LBW children (9.1%). There is a significant relationship between maternal age (0.048), history of maternal illness (0.034), nutritional status during pregnancy (0.001), and low birth weight (0.012) with the incidence of stunting and there is no significant relationship between the spacing of pregnancies (1.000) and the incidence of stunting.

Authors: Alshariah Namran , Al Salah Abdullah , Alzamanan Khaled , Al Abbas Ibrahim , Alyami Abdulah , Alyami Abdulhadi , Alalhareth Khalid
Published: February 2024

Introduction: Needlestick and Sharp Injuries (NSSIs) pose a significant threat to healthcare workers, particularly in Operating Theatres (OTs), where the risk of exposure is compounded by high-stress environments and the complexity of procedures. Despite the known dangers, a persistent issue of underreporting complicates efforts to safeguard worker and patient health. This paper promotes the adoption of Evidence-Based Practice (EBP) to mitigate these risks, aiming to improve reporting behaviors and, by extension, overall safety within healthcare settings. Methods: This study utilizes a qualitative research approach, combining literature review and case studies to explore the phenomena of NSSI underreporting among healthcare workers. It examines barriers to reporting within OTs, such as fear of repercussions and time constraints, and proposes interventions based on EBP. Research methodology emphasizes the application of theory to practice through multidisciplinary team involvement, workshops, and the establishment of clear, achievable goals. Results: The investigation reveals that while healthcare workers are generally aware of the protocols for reporting NSSIs, a range of barriers inhibits consistent application in practice. The study identifies effective strategies for bridging the theory practice gap, including fostering a constructive learning environment, ensuring leadership support, and promoting open communication. These strategies are shown to facilitate the practical application of theoretical knowledge, thereby improving reporting rates and enhancing safety protocols in OTs. Conclusions: Effectively addressing NSSIs in healthcare settings, particularly in Operating Theatres, requires a comprehensive approach that encompasses education, clear reporting protocols, and a culture of collective responsibility. Bridging the gap between theoretical knowledge and practical application through workshops, evidence translation, and an emphasis on interdisciplinary collaboration is key to enhancing patient and worker safety. The study underscores the necessity of understanding the multifaceted nature of behavior change in healthcare environments to implement successful EBP strategies.

Authors: TISCAREÑO FELIX JULIETA , ALBAJEZ GARCIA JOSE ANTONIO , SANTOLARIA MAZO JORGE
Published: February 2024

The challenges arising from mass production with high quality level require advanced error measurement systems and optical metrology systems. Nowadays, it is more frequent to find this type of controls at the manufacturing industry into the quality control procedures as long as the need for a faster capture speed and precision has increased. However, these techniques can be improved. The accuracy of 3D measurement systems formed by a camera-projector pair depends directly on the calibration procedure used. The projector is usually modelled as the inverse projection of a pin-hole camera, which presents the option to calibrate the system by two different approaches: as a whole system or separately. The most common approach is the use of a camera previously calibrated, followed by the calibration of the projector. Studies show that the uncertainty of the camera parameters from its calibration propagates to the projector parameters and several authors conclude that the three most widespread are: Tsai, Zhang and Direct Linear Calibration. The objective of this study is to have a clear comprehension of the relationships between the camera and projector parameters and of how uncertainty is propagated to the measurement system error. Therefore, the three calibration methods previously mentioned and some of them possible combinations are analyzed.

Although the computational power of embedded systems has increased in recent years, these systems are increasingly being taxed with more tasks. This raises the interest for computationally lean algorithms which are able of rendering process operation more efficient and reliable. This is particularly relevant in the case of flight computers for autonomous aircraft. Fault detection, isolation and identification assist in management strategies to improve both predictive maintenance and operational safety. This article combines a principal component–based representation with multivariate statistics to detect and isolate anomalies in a process. The resulting algorithm is computationally lean and was validated with respect to experimental measurements in a turbojet before and after years of operation. The results show that the developed algorithm is capable of successfully determining the fouling components in the turbojet.

Implicações da presença de equídeos em áreas urbanas no Brasil
Authors: De Camargo Debortoli Elísio , Lemes Jaqueline Schneider
Published: February 2024

RESUMO CONDENSADO
A equideocultura é uma atividade relevante da produção agropecuária nacional. Sabe-se que nas grandes metrópoles nacionais os equídeos urbanos são usados quase que exclusivamente para tração. Já em cidades menores, encontram-se nas áreas urbanas, animais tanto de tração quanto de esporte e lazer. A presença dos equídeos em áreas urbanas levanta questionamentos sobre os pontos críticos relacionados ao bem-estar animal e à saúde única (animal, humana e ambiental), bem como a necessidade do desenvolvimento de políticas públicas para a melhoria das condições dos equinos nessas áreas. O convívio com animais, em áreas urbanas e peri-urbanas requer cuidados que, se ignorados, podem trazer consequências indesejadas, tais como acidentes de trânsito ou de agressões, na interação animal-humano. No entanto, proibir a permanência de cavalos de tração, por exemplo, pode gerar impactos na sobrevivência de uma parcela vulnerável da população. Ou seja, é notória a necessidade de políticas públicas e de educação ambiental que orientem a população sobre a interação, uso e responsabilidade com os animais domésticos.
An integrated framework for techno-enviro-economic assessment in nanogrids
Authors: El Sayed Ahmad , Poyrazoglu Gokturk , E. E. Ahmed Eihab
Published: February 2024

This paper presents an integrated framework designed for capacity planning of grid-connected nanogrid, a small solar and energy storage system that can provide kilowatt-level services to individual buildings. This framework comprehensively evaluates nanogrid cost-effectiveness, sustainability, and reliability, employing a multi-faceted techno-enviro-economic assessment approach. Traditional nanogrid capacity planning often prioritizes peak load requirements, which may lack optimality owing to occasional peak load occurrences. Conversely, optimizing solely for base load requirements might also fall short of effectiveness, compromising reliability and sustainability objectives. The proposed framework employs a three-step, integrated process for nanogrid (NG) capacity planning. Firstly, the Planner module identifies optimal asset sizing considering a two-day look-ahead logic. Then, the Operator module serves as a digital twin for the system, conducting hourly calculations over a short-term horizon. Lastly, the Evaluator module evaluates technical, environmental, and economic metrics for each solution, assessing the effectiveness of asset-sizing decisions. A simulated case study has demonstrated the effectiveness of the proposed framework. The technical assessment revealed that a PV size of 24 kW and a storage capacity of 91 kWh led to the most reliable solution, with a probability of local sufficiency of 95 percent. Furthermore, the environmental assessment showcased a renewable fraction of 94% with a PV size of 26 kW and a storage of 85 kWh. Economically, the analysis identified that a PV size of 12 kW and a storage size of 24 kWh led to the minimum total cost. In contrast, a PV size of 26 kW and a storage size of 85 kWh yielded a total operating savings of $4,801.

Gratitude is acceptance of one's condition in any condition. This attitude is crucial for Christians to have as a form of respect for God's sovereignty. However, the importance of this attitude is often not found in Christians, especially when experiencing difficult times. One of the reasons is the belief that the blessings given by God are only material things in the form of wealth. This view then influences the gratitude of people who receive God's blessings. To anticipate the formation of this thought pattern, guidance is needed in understanding God's blessings as a whole. This coaching activity is intended to answer this problem. Using research results that have been published regarding God's blessing in Deuteronomy 28:1-14, the implementers carry out coaching using the lecture method. The coaching targets two mutual aid communities in Batam City, OMEFA and Family Batam. The participants were given coaching in four stages to provide a complete understanding of God's various blessings, which are very broad. This coaching is expected to make participants aware of God's blessings apart from material wealth.

Authors: Sharma Rahul , Katkar Anand , Bhanage Ashok , G Premkumar Reddy
Published: February 2024

Background: Cerebral venous sinus thrombosis (CVST) is a rare cerebrovascular condition characterized by the formation of blood clots in the cerebral venous sinuses, which are responsible for draining blood and cerebrospinal fluid from the brain. CVST represents a significant cause of stroke in young individuals, with a mortality rate ranging from 6% to 15%. Methods: Common clinical presentations include symptoms like headaches, seizures, altered mental state, and focal neurological deficits. In India, a noteworthy occurrence of CVST is observed among postpartum women, while alcoholism poses a significant risk factor for males. Results: This study identifies headaches as the most prevalent initial symptom of CVST, followed by seizures and focal neurological deficits. The superior sagittal sinus is the most frequently affected in these patients. Notably, 83.3% of patients in this study achieved a favorable outcome. However, a midline shift exceeding 10mm was identified as a predictive factor for an unfavorable outcome in this series. Conclusions: Contrary to previous perceptions, CVST is not uncommon in males. The early diagnosis and prompt intervention have a positive impact on overall patient outcomes. This research sheds light on the importance of recognizing CVST in a broader demographic, its common symptoms, and the critical role of timely intervention for improved patient prognosis.

Published: February 2024

Background: Incidence and recognition of the congenital anomalies involving vas (or) ductus deferens, also called as sperm duct, are low, particularly when duplication of the sperm duct and epididymis occurs together. These anomalies, although of rare incidence, should be considered while performing surgeries related to the spermatic cord, to prevent inadvertent damage. Case presentation: We, here, present a case of a seventeen year old boy with undescended testis on left side, where laparoscopic evaluation revealed polyorchidism. The accessory testis was removed, and histo-pathological examination confirmed duplication of the sperm duct and the epididymis. Conclusion: This case scenario highlights the importance of recognizing and managing rare urogenital anomalies during procedures involving handling of spermatic cord structures.
NUCLEAR LABORATORY SETUP FOR MEASURING THE SOIL WATER CONTENT IN ENGINEERING PHYSICS TEACHING LABORATORIES
Authors: Prathap Dr.K. , ANUPAMA M.
Published: February 2024

One important soil parameter that is measured in many engineering, geology, soil and environmental science investigations is the soil water content (θ). For example, θ influences the assessment of soil strength, hydraulic conductivity, groundwater recharge, and soil aeration condition. Measurement of θ is essential for tracking and managing a number of soil processes. A quick and non-destructive method for determining μ in soils with drastically different compositions is the gammaray attenuation (GRA) approach. However, lab physics classes rarely cover GRA. An experiment involving the measurement of θ using a teaching GRA apparatus is proposed. A Geiger-Müller detector, a radiation counter, and a radioactive source with a 37Cs decay were the components of the experimental setup. Four different granulometric compositions of soil samples were examined. The transmitted gamma-ray photon intensity and θ were found to have strong linear relationships (correlation coefficients ranging from -0.95 to -0.98). There were variations in the soil porosity between the traditional and GRA techniques, ranging from around 7.8% to about 18.2%. Furthermore, a robust linear correlation (correlation coefficients ranging from 0.90 to 0.98) was noted between the GRA and the conventional gravimetric technique for measuring θ. The effectiveness of the teaching GRA apparatus in measuring θ was confirmed. Additionally, the device enables undergraduate students from a variety of subject areas to be introduced to a few significant facets of the study of contemporary physics.

Published: February 2024

This paper proposes an approach for the hybrid solar photovoltaic and Battery management for stand-alone applications. Battery charging process is non-linear, time-varying with a considerable time delay so it is difficult to achieve the best energy management performance by using traditional control approaches. A fuzzy control strategy for battery charging or discharging used in a renewable power generation system is analyzed in the paper. To improve the life cycle of the battery, fuzzy control manages the desired state of charge. A fuzzy logic-based controller to be used for the Battery SOC control of the designed hybrid system is proposed. This paper presents a general description of the implemented microgrid topology. The exact linearization theory adapted for power converters is applied to both a Single-Ended PrimaryInductor converter (SEPIC) to extract energy from PV modules and to a Boost converter to increase the voltage. The entire designed system is modeled and simulated using MATLAB/Simulink environment.
THE USE OF AN RBF NEURAL NETWORK AND A GENETIC ALGORITHM FOR MULTI-OBJECTIVE OPTIMISATION OF A CENTRIFUGAL PUMP VOLUTE
Authors: Aloori Mrs. Radha , Suresh Mr. S , Ollam Mr. Avinash
Published: February 2024

When it comes to the construction of hydraulic structures, the hydraulic performance and acoustic performance of centrifugal pumps are connected and conflicting. In order to find a solution to this issue, a technique for optimising the design of a volute that is based on a radial basis function (RBF) neural network and a genetic algorithm (GA) has been developed. The effectiveness of the centrifugal pump as well as the total amount of sound pressure level are employed as the targets for optimisation. The factors that are used for optimisation purposes are the installation angle of the volute tongue, the height of the volute diffuser tube, the installation angle of the volute tongue, and the diameter of the base circle. The Latin hyper-cube sampling (LHS) method is used to construct the sample space. The RBF neural network method is used to develop the agent model between the optimisation variables and goals. Finally, the GA method is utilised to do multi-objective optimisation. In order to do a comparative investigation of the hydraulic and acoustic performance of the persons in the Pareto solution set under a variety of different working situations, the initial individuals and two individuals from the set's extremes are chosen. The findings indicate that under the rated working conditions, the efficiency of the optimal individual of efficiency increases by 3.79%, while the internal noise of the optimal individual of sound pressure level decreases by 5.5% and the external noise decreases by 2.3%. The results also show that the initial individual had a lower level of efficiency than the optimal individual.
ANALYSIS OF THE FREQUENCY-DOMAIN CORRELATION TECHNIQUE FOR DETECTING IMPACT DAMAGES AND DETERMINING THE DYNAMIC RESPONSES OF RC BRIDGE PIERS
Authors: Karnakar Y. , Kumari M. Santhosha , Kumar G. Sunil
Published: February 2024

In this work, we looked at the possibilities of frequency-domain-based correlation approaches (damage correlation indices) in the area of impact damage detection in reinforced concrete columns. For this work, researchers used a novel ultra-high drop hammer experiment technique to model the effects of medium-sized vehicles striking bridge piers by hitting four scaled-down reinforced concrete pier components. Using an acceleration acquisition device, the frequency response functions of the members were measured both before and after the damage occurred. As shown in the experiments, the damage correlation indexes (DCI) that accounted for the multi-order modal frequencies correctly identified the piers' damage levels. In addition, using the commercial software LSDYNA, an impact finite element model and a modal analysis technique were constructed, both of which were matched with the trials. Finally, the impact processes between medium-sized vehicles and reinforced concrete piers were simulated using a setup of the finite element parameters that matched the experimental data. Based on damage indices, a peak impact force (PIF) formula for vehicle impact situations was presented to ensure that structural design specifications are met.
ON THE COUNTING FUNCTION OF SEMIPRIMES

Published: February 2024

A semiprime is a natural number which can be written as the product of two primes. The asymptotic behaviour of the function π2(x), the number of semiprimes less than or equal to x, is studied. Using a combinatorial argument, asymptotic series of π2(x) is determined, with all the terms explicitly given. An algorithm for the calculation of the constants involved in the asymptotic series is presented and the constants are computed to 20 significant digits. The errors of the partial sums of the asymptotic series are investigated. A generalization of this approach to products of k primes, for k ≥ 3, is also proposed.
SECURE DATA GROUP SHARING AND CONDITIONAL DISSEMINATION WITH MULTI-OWNER IN CLOUD COMPUTING
Authors: Shenigaram Vidhya , Thakur Susheel Kumar , Kumar Choul Praveen , Maddikunta Laxman
Published: February 2024

With the rapid development of cloud services, huge volume of data is shared via cloud computing. Although cryptographic techniques have been utilized to provide data confidentiality in cloud computing, current mechanisms cannot enforce privacy concerns over cipher text associated with multiple owners, which makes co-owners unable to appropriately control whether data disseminators can actually disseminate their data. In this paper, we propose a secure data group sharing and conditional dissemination scheme with multi-owner in cloud computing, in which data owner can share private data with a group of users via the cloud in a secure way, and data disseminator can disseminate the data to a new group of users if the attributes satisfy the access policies in the cipher text. We further present a multiparty access control mechanism over the disseminated cipher text, in which the data co-owners can append new access policies to the cipher text due to their privacy preferences. Moreover, three policy aggregation strategies, including full permit, owner priority and majority permit, are provided to solve the privacy conflicts problem caused by different access policies. The security analysis and experimental results show our scheme is practical and efficient for secure data sharing with multi-owner in cloud computing.

The study examined health seeking behavior towards hypertension among adult traders in Ahia Ohuru Market Aba, Abia State. The state was randomly selected while the market was purposively chosen because it was one of the largest. Thereafter, 342 adult traders were selected by balloting. Information on adults’socio-demographic and health seeking behavior were gathered using questionnaire. Digital automatic blood pressure monitor was used to measure their blood pressures. Frequencies and percentages were used to analyze data collected while association was tested using chi square.  Result showed that 35.3% and 14.9% visited private and government health facilities, respectively while 4.1% sought traditional health practitioners and 2.3% faith healers. On self-medication with herbal drugs, 22.5% and 28.1% did that most times when they were ill and for illness they considered severe. For pharmaceutical drugs, 46.5% and 14.2% self-medicated with them when sick and did that for mild illnesses most times, respectively  Blood pressure readings revealed that 39.4% had normal, 30.8% were pre-hypertensive and 18.9% and 10.9% had stages I and II hypertension, respectively. Association between adults’ health seeking behavior and blood pressure was positive and significant with visit to private health facility, self -medication with herbal, pharmaceutical drugs and faith healers with X2 and p-values of 12.56; 0.057, 23.67; 0.036, 27.56; 0.027 and 17.34; 0.043, respectively. In conclusion, seeking health care in questionable places or self- medication plus other factors may adversely affect onset and progression of hypertension.
Effect of Rainfall on Water Parameters in Recreational Lakes in Heidelberg, Germany

Published: February 2024

This study evaluates the impact of precipitation on water quality in Heidelberg, Germany’s recreational lakes during sporadic rainfall events from August to September 2023. Data were collected from five stations, monitoring physicochemical properties and nutrient levels before and after rainfall. Measurements of dissolved oxygen, pH, conductivity, and redox potential were conducted in situ, while turbidity, nitrates, phosphates, sulphates, zinc, and copper levels were analyzed in the SRH Heidelberg water laboratory. Findings indicate pH levels increased due to dilution effects, while conductivity rose due to runoff, enhancing ion concentration in the lakes. Dissolved oxygen levels also increased, attributed to aeration from rainfall-induced surface turbulence. Redox potential decreased, reflecting atmospheric oxygen dissolution. Nutrient concentrations, including nitrates and phosphates, along with sulphates, declined post-rainfall, suggesting a dilution effect without significant impact from surface runoff. This outcome implies the absence of major nutrient and sulphate sources upstream. Heavy metals like zinc and copper also decreased in concentration, indicating no introduction through runoff or sediment transport. The study underscores the variability of water quality parameters across different lakes, influenced by factors such as water sources, surrounding land use, geological conditions, and lake characteristics. Overall, water quality improved post-rainfall, making the lakes suitable for recreational activities, with the study establishing a non-linear correlation among the water quality parameters and deducing the P ratio for each parameter.
