Published: September 2024

There are more plastic cards in the wallet than currency notes. This change is because the Indian banking industry, is going through an IT revolution to be competitive with the other developed and developing nations and other regulatory reason has led to total banking automation in the Indian Banking Industry. According to KPMG-CII report, India has the capability to become the third largest by 2025 and fifth largest in the world by 2020 in the banking industry. Also, India’s banking industry is worth Rs. 81 trillion and it is utilising latest internet infrastructure to be competitive to other economies. The Indian banking system consists of 26 public sector banks, 20 private sector banks, and 43 foreign banks, together with 61 regional rural banks (RRBs) and over 90,000 credit cooperatives. The change towards internet banking is intensified by the changing dynamics in India as it is about to become one of the youngest countries in the world by 2020, the average age being 29 years. And this young population is technology savvy and wants real time online information. As the users of the online banking will increase rapidly in the years to come, these systems are becoming the most likely targets of hackers and cyber criminals. Banking institutions must take all measures to make online banking system safe, to maintain the customer trust and satisfaction level for online banking. To be protected by the cyber security threat banking institutions will have to develop effective and efficient customer awareness programs as safety from cyber threats related to bank are equally interdependent 2024on the level of awareness of using the banking online system and does not solely depend on the safeguards and practices implemented by the bank. This makes it very difficult for banking institutions to maintain the confidentiality and integrity of the banking system. The research will try to assess whether there is awareness of threats of online banking among the users that comprise online banking and to further analyse whether there is a difference in awareness of the users on the basis of Age and Gender.
VR gamification for cognitive assessment: evaluating visual search, response inhibition, and visual short-term memory (Preprint)
Authors: Hadjiaros Marios , Shimi Andria , Neokleous Kleanthis , Pattichis Constantinos , Avraamides Marios
Published: September 2024

BACKGROUND

Cognitive tasks are essential tools in psychology and neuroscience research, offering insights into various mental processes such as attention, perception, and memory. These tasks often involve simple stimuli, such as alphanumeric characters and shapes, and a large number of trials, a deliberate design choice aimed at controlling for extraneous variables and ensuring the reliability of the results. While this methodological approach is crucial for maintaining experimental rigor and validity, it may inadvertently lead to issues regarding participant engagement.

OBJECTIVE

The main objective of the present empirical study was to investigate whether gamified versions of 3 established cognitive tasks, namely the Visual Search, the Whack-the-Mole, and the Corsi block tasks yield the same patterns of results as their traditional counterparts. These three tasks were chosen because they are commonly used to assess attention and visual short-term memory, which are crucial for many everyday tasks.

METHODS

Participants executed our gamified versions of the Visual Search, the Whack-the-Mole, and the Corsi Block in one of three conditions: in Immersive Virtual Reality (VR-Lab), in a desktop VR environment presented in the lab (Desktop-Lab), and in a desktop VR environment experienced at home (Desktop-Remote).

RESULTS

The pattern of results from these gamified tasks replicated those reported in the literature about their traditional counterparts that typically employ simple stimuli and are longer in duration. Notably, some differences in findings were observed across the three administration conditions (VR-Lab, Desktop-Lab, and Desktop-Remote). In the Visual Search and the Whack-the-Mole tasks participants were 250ms and 70ms faster to respond in the VR-Lab than in the Desktop-Lab condition. Moreover, in the Whack-the-Mole task, participants were 160ms faster when carrying out the task in the Desktop-Lab than in the Desktop-Remote condition.

CONCLUSIONS

Despite these differences, overall, the findings of the study confirm the potential of VR technology as a tool for assessing cognitive performance with tasks that can potentially increase participant engagement.

Sustaining cardiac rehabilitation delivery throughout COVID-19 lock-down: results from the SCRAM telerehabilitation randomized controlled trial. (Preprint)
Authors: Maddison Ralph
Published: September 2024

BACKGROUND

Accessibility barriers contribute to low participation in center-based cardiac rehabilitation. We developed an innovative, comprehensive, dual-phase telerehabilitation program to address this gap (Smartphone Cardiac Rehabilitation Assisted Self-Management; SCRAM).

OBJECTIVE

To determine the effectiveness of SCRAM for increasing maximal aerobic exercise capacity (VO2max).

METHODS

A multi-center, parallel two-arm randomized controlled trial recruited clinically stable adults (aged 18+ years) with diagnosed coronary heart disease at three hospitals in Victoria, Australia (Melbourne, Geelong, Bendigo) from 2018-2021. Participants were randomized (1:1), stratified by sex and study site, to receive SCRAM plus usual cardiovascular care (intervention), or usual cardiovascular care alone (control). SCRAM intervention provided 24 weeks of remote exercise supervision, coaching, and behavior change support via smartphone. Usual cardiovascular care included standard medical care and advice to seek a referral to centre-based cardiac rehabilitation (CR), which was heavily impacted during the COVID-19 pandemic. Due to the nature of the treatments, participants were not blinded to allocation; primary outcome assessors and biostatisticians were blinded. The primary outcome was VO2max at 24 weeks, analyzed on the principle of intention-to-treat, using linear regression adjusted for baseline and stratification factors on multiple imputed data.

RESULTS

Recruitment and data collection were heavily impacted by COVID-19, although SCRAM delivery was sustained throughout. Of 220 required participants, only 123 (56%) were recruited and randomized (intervention n=63, control n=60); 45% had missing VO2max at 24 weeks—largely due to enforced COVID-19 restrictions. VO2max at 24 weeks favored SCRAM, but this was not statistically significant (mean difference=1.61 ml/kg/min; 95% CI [-1.38, 4.61], P=.28). Among secondary outcomes, patients receiving SCRAM had lower diastolic blood pressure at 24 weeks (mean difference=-5.54 mmHg; 95% CI [-10.01, -1.06]).

CONCLUSIONS

SCRAM was resilient to COVID-19-related disruptions to CR delivery but, while findings were inconclusive, it did not lead to a clinically important difference in VO2max. Further research is needed to conclusively assess treatment effects, and understand how virtual CR delivery models can be translated into routine practice.

Conclusiones. Mirar al futuro: la democracia en tiempos pospandémicos
Authors: López Leyva Miguel Armando , Montes de Oca Barrera Laura Beatriz
Published: September 2024

Una de las premisas que está detrás de los capítulos que integran esta obra es que la pandemia por la enfermedad de COVID-19 representa un hito global. en Democracia en tiempos difíciles nos interesó centrar la atención en la vida política con el fin de responder una pregunta amplia: ¿de qué manera la pandemia ha impactado en el actuar de los gobernantes, en la forma en que las decisiones son tomadas y, en última instancia, en cómo se condujeron los asuntos públicos para atender y contener la crisis sanitaria? Desde tres ejes analíticos —régimen, políticas públicas y poderes públicos— en los nueve capítulos de este libro nos interesó analizar cómo se adaptaron los procesos y las instituciones políticas al contexto pandémico. De alguna manera ello implicó un cambio en el quehacer de la política institucional. el primer punto que queremos resaltar en estas líneas. Al considerar el hito que representó la pandemia, y tenerla como marco para el análisis la democracia mexicana, ¿qué cambió y qué se mantuvo en las instituciones, los procesos y los actores políticos?, ¿qué reflexiones y retos tenemos frente a la nueva realidad que se ha producido? El segundo punto tiene que ver con el futuro. La intención de esta reflexión es dejar de pensar el futuro como una caja vacía en la que nuestras acciones presentes para enfrentar los desafíos mundiales no tienen consecuencias. En ese sentido, Zakaria (2021) hace un recorrido breve en distintas etapas de la historia para sostener lo que parecería obvio: “las epidemias tienen consecuencias”. En esa línea, con esta reflexión asumimos la propuesta de “democratizar los futuros”, es decir, eso que se ha considerado como una “planificación posmoderna” que permita anticipar y atender problemáticas complejas (wicked problems) como las catástrofes climáticas y las pandemias, pero también la acumulación de poder y la desigualdad, los límites de los Estados y los mercados, la guerra, la violencia y el crimen organizado, además de toda una serie de “incógnitas desconocidas” (Urry, 2016: 13) que nos impelen a proponer ideas.
El poder Legislativo mexicano en tiempos de pandemia: innovaciones y nuevos constreñimientos institucionales
Authors: Puente Martínez Khemvirg
Published: September 2024

En el contexto de la pandemia por COVID-19, el poder Legislativo federal en México evidenció sus fragilidades institucionales para garantizar estabilidad al trabajo parlamentario, para darle continuidad al ejercicio de sus funciones básicas y para permitir la participación libre de legisladores y de la sociedad en los procesos deliberativos. Durante el inicio de la pandemia, el marco jurídico hasta entonces vigente imposibilitó el funcionamiento continuo de los plenos de las cámaras, de sus sistemas de comisiones y un proceso legislativo que permitiera la deliberación que las legislaturas requieren. No obstante, en ambas cámaras se lograron innovaciones tecnológicas y rutas alternativas para darle continuidad al trabajo parlamentario que fueron incorporadas a su actividad cotidiana. En este capítulo se describen los principales retos que enfrentó el poder Legislativo federal para hacer frente a la emergencia y reiniciar el desempeño de sus funciones constitucionales, las adaptaciones normativas y organizacionales para reactivar parte de la vida parlamentaria. El presente trabajo está organizado en tres secciones: en la primera de ellas se explica por qué la continuidad y estabilidad es un valor fundamental de las organizaciones parlamentarias en una democracia y cuáles son los elementos vitales para garantizar dicha continuidad; en la segunda parte también se describen las condiciones iniciales (de integración y reparto del poder Legislativo) necesarias para comprender cómo, para el caso de México, la pandemia afectó negativamente las actividades legislativas y propició una parálisis institucional en ambas cámaras del congreso federal debido a las limitaciones normativas y de ausencia de fuentes de derecho parlamentario (formal y material) que permitieran la continuidad de los trabajos legislativos, en la tercera sección se evalúa el desempeño institucional de las cámaras en la actividad parlamentaria y de forma particular en la continuidad institucional, la actividad legislativa, su capacidad deliberativa y para supervisar el desempeño del gobierno. De esa forma, se podrán documentar las principales acciones y omisiones del poder Legislativo y sus integrantes en el contexto de la emergencia de salud.

Handbook for Quantifying Robustness of Magic
Authors: Hamaguchi Hiroki , Hamada Kou , Yoshioka Nobuyuki
Published: September 2024

Nonstabilizerness, or magic, is an essential quantum resource for performing universal quantum computation. Specifically, Robustness of Magic (RoM) characterizes the usefulness of a given quantum state for non-Clifford operations. While the mathematical formalism of RoM is concise, determining RoM in practice is highly challenging due to the necessity of dealing with a super-exponential number of stabilizer states. In this work, we present novel algorithms to compute RoM. The key technique is a subroutine for calculating overlaps between all stabilizer states and a target state, with the following remarkable features: (i) the time complexity per state is reduced {exponentially}, and (ii) the total space complexity is reduced {super-exponentially}. Based on this subroutine, we present algorithms to compute RoM for arbitrary states up to n=8 qubits, whereas the naive method requires a memory size of at least 86 PiB, which is infeasible for any current classical computer. Additionally, the proposed subroutine enables the computation of stabilizer fidelity for a mixed state up to n=8 qubits. We further propose novel algorithms that exploit prior knowledge of the structure of the target quantum state, such as permutation symmetry or disentanglement, and numerically demonstrate our results for copies of magic states and partially disentangled quantum states. This series of algorithms constitutes a comprehensive ``handbook'' for scaling up the computation of RoM. We envision that the proposed technique will also apply to the computation of other quantum resource measures.

que o realismo crítico tem a dizer sobre os debates Mainstream, ortodoxia e heterodoxia no pensamento econômico brasileiro recente
Authors: Aguilar Filho Hélio Afonso de Aguilar , Schneider Bruno Genro
Published: September 2024

O interesse pelo Realismo Crítico tem crescido entre os economistas, sobretudo devido a ênfase de Tony Lawson na ontologia como critério para se entender o escopo da Economia e as deficiências da abordagem mainstream. No Brasil, o debate sobre o estado atual da Economia também recorre à filosofia da ciência, motivado principalmente pela investigação de critérios de demarcação científica, com os adeptos do mainstream buscando argumentos para expurgar os não conformistas da prática legítima da ciência. Baseando-se no Realismo Crítico, este artigo busca analisar como o pensamento brasileiro recente lida com as classificações e separações estabelecidas por categorias como mainstream, ortodoxia e heterodoxia. Mais especificamente, investiga-se como são relacionadas perspectivas econômicas, ontologia e método no pensamento econômico brasileiro a partir do debate do final dos anos 1990 envolvendo Marcos Lisboa e as contraposições heterodoxas de Cardim, Duayer, Painceira e Medeiros.

Authors: Pratami Febtin , Marwa Taufiq , Andaiyani Sri , Abukosim Abukosim
Published: September 2024

This study analyses the factors that influence property prices in Indonesia using secondary data from 2008QIII to 2021QII and the Ordinary Least Square (OLS) analysis technique. The study re-sults show that inflation and lending rates have a negative and significant effect on property prices. Economic growth has a positive but insignificant effect, while exchange rates and Loan to Value (LTV) have a positive and significant effect on property prices. The findings suggest that LTV can be used as a tool to control credit growth. An increase in LTV ratio accelerates property credit growth, while a decrease in LTV ratio can slow down credit growth. The recommendation of this study is for the monetary authority to ensure the right time to implement LTV policy in Indonesia.

Published: September 2024

A possible way to increase the operating speed and field capacity of a cultivator-fertiliser is to modify its configuration scheme. According to our hypothesis, placing the fertiliser hopper directly on the tractor frame could reduce the traction resistance of the cultivator-fertiliser and consequently increase its operating speed and field capacity. Validating this hypothesis requires a comparative evaluation of the existing configuration schemes for cultivator-fertilisers. However, there are currently no such comprehensive studies available. This research aims to develop a mathematical model for conducting a comparative theoretical evaluation of various configuration schemes for cultivator-fertilisers. The development of this model incorporated principles from classical and agricultural mechanics. We developed a mathematical model and conducted a theoretical evaluation of existing configuration schemes for cultivator-fertilisers, such as mounting the hopper on a separate trailed chassis, mounting the hopper and tillage working bodies on one frame, and mounting the hopper directly on the tractor frame. The working width of the cultivator-fertiliser was constant and amounted to 6.2 m. The effective engine power of the tractor was taken to be 220 × 103 W. It was found that placing the fertiliser hopper on the tractor frame maximises the field capacity to 3.9 ha∙h−1. The increase in field capacity was 8.9–16.0%. In this case, the fertiliser hopper volume should be 1.89 m3 and travel speed 8.45 km∙h−1.
Predicting Mechanical Strength and Optimized Parameters in FDM-Printed Polylactic Acid Parts Via Artificial Neural Networks and Desirability Analysis
Authors: Abdulridha Hind H. , Abbas Tahseen F. , Bedan Aqeel S.
Published: September 2024

Fused deposition modeling (FDM) is a commonly used additive manufacturing (AM) technique in both domestic and industrial end-product fabrications. It produces prototypes and parts with complex geometric designs, which has the major benefits of eliminating the need for expensive tooling and flexibility. However, the produced parts often face poor part strength due to anisotropic fabrication strategies. The printing procedure, the kind of material utilized, and the printing parameters all have a significant impact on the mechanical characteristics of the printed item. In order to predict the mechanical properties related to printed components made with the use of FDM and Polylactic Acid (PLA) material, this study concentrates on developing a prediction model utilizing Artificial Neural Networks (ANNs). This study used the Taguchi design of experiments technique, utilizing (L25) orthogonal array as well as a Neural Network (NN) method with two layers and 15 neurons. The effect of FDM parameters (layer thickness (mm), percentage of infill density, number of top/bottom layers, shell thickness (mm), and infill overlap percentage) on ultimate tensile and compressive strength (UTS and UCS) was examined through analysis of variance (ANOVA). With an ANOVA result of 67.183% and 40.198%, respectively, infill density percentage was found to be the most significant factor influencing UCS and UTS dependent on other parameters. The predicted results demonstrated valuable agreement with experimental values, with mean squared errors of (0.098) and (0.326) for UTS and UCS, respectively. The predictive model produces flexibility in selecting the optimal setting based on applications.

Intestinal ultrasound is a new non-invasive imaging method that can be used for diagnostics of inflammatory bowel disease, to evaluate the response to therapy, and monitor serious complications of the disease in time. A prospective study was performed in Pauls Stradiņš Clinical University Hospital. Thirty patients were enrolled in the study: 21 patients with ulcerative colitis and 9 patients with Crohn’s disease. Intestinal ultrasound was performed using Diagnostic Ultra-sound System Arietta S70 (Hitachi, Japan). Intestinal wall structure (thickness), blood flow (Limberg score), intraluminal content, mesenteric fat hypertrophy and lymph nodes were evaluated, and laboratory markers of inflammation and clinical activity indices were analysed. Increased bowel wall thickness (BWT) (≥ 3 mm) was detected in 22 patients (73.3%), and wall stratification in 17 patients (56.7%). Using statistical analysis, it was concluded that there was a positive and statistically significant correlation between bowel wall thickness and ferritin (r = 0.60; p < 0.001), CRP (r = 0.49, p = 0.006), and faecal calprotectin (r = 0.84, p < 0.001). Intestinal ultra-sound is a promising real time monitoring method for both Crohn’s disease and ulcerative colitis, which showed statistically significant correlations between bowel wall thickness, bowel wall stratification, blood flow, laboratory markers of inflammation and clinical activity indices.

Aceh Selatan is the oldest district in Aceh Province, located on the edge of the Banda Aceh – Medan west cross highway consisting of mountainous areas, lowlands, and water areas (Hindia Ocean). The problem at this time is that 54% of the people of South Aceh Regency do not have proper access to latrines and drainage channels, which are the target for receiving domestic wastewater. There is no public awareness of the importance of providing and maintaining domestic wastewater facilities and infrastructure. This research aims to sustainably carry out regional-scale domestic wastewater management based on Maqashid Syari’ah. The method used in the research is to determine the target of wastewater handling in South Aceh Regency until 2040 to determine the development model and strategy. Meanwhile, the zoning method was used to determine the planning area. Labuhan Tarok Village, Meukek District, South Aceh Regency, is one of the villages in urgent priority scale wastewater treatment with the An Aerobic Baffled Reactor (ABR) model. The reduction of BOD, COD, and TSS can be made with this treatment model in accordance with the Quality Standard of Peraturan Menteri Lingkungan Hidup dan Kehutanan No. 68 of 2014 and accordance with Permen PUPR No.4 of 2017, concerning the Implementation of Domestic Waste Water Management Systems.

The global rise in industrial activity is leading to unprecedented environmental degradation. To combat this trend, industries must adopt a proactive approach toward environmental sustainability. Eco-innovation, defined as introducing new products, manufacturing processes, or management practices that reduce environmental risks, is essential in this effort. While general industry models for assessing eco-innovation maturity exist, there is a notable lack of such models tailored specifically for the food industry. This article aims to bridge this gap by contributing to the current understanding of eco-innovation maturity assessment indicators for food industries. We present findings from a systematic literature review conducted across three databases, covering publications from 2018 to June 2024. This research focused on identifying indicators suitable for evaluating eco-innovation maturity specifically within the food industry, as the existing models predominantly cater to general industries. The study concludes that assessing eco-innovation maturity in the food industry is feasible and proposes indicators for evaluating companies within this sector.

As we tend towards more electric power distribution networks including distributed energy resources (DERs) which are increasing in terms of power capability and requirements. The design of the electric ship power and distribution system follows suit with the added challenge of achieving smaller footprint on islanded power distribution networks. These challenges are namely, equipment and conductor sizes, including the associated infrastructure such as interconnecting power cables, copper busbars and the associated supporting installation equipment including cable trays and ladders. Additionally, noise & vibration, shock, and other environmental factors along with the associated forces during fault events such as short circuits and the insulation challenges particularly on MV system must be considered. The selection criteria for using MV or LV technology is therefore non-trivial, and not limited to only the best technologies available at the time of consideration, but, to other considerations including cost, technology readiness level (TRL) of equipment, power density and feasibility of installation and integration among some of the overall considerations. A clear understanding of the advantages & disadvantages of LV and MV technology leads to the design of better systems that can future-proof the capability of the electric grid and enables the use of clean energy at larger scale using sources such as hydrogen or similar fuel cells and batteries, which are modular and well suited for power stages inherent in converter technologies. A novel solution using an LV DC to / from MV DC converter topology patented by GE-PC, allowing greater flexibility in MV-DC systems, while maintaining a smaller footprint is presented in this paper. This paper aims to examine the various factors involved in specifying an electrical power system with supporting power equipment holistically and how these factors can affect the decision based on the use of MV or LV technologies.

The main purpose of this study was to assess the influence of management of human resources on the quality of education in selected private universities in Kenya. The study aimed to investigate the perceptions of the deans of schools, heads of departments, and lecturers towards the management of human resources and the quality of education in private universities in Kenya. The study used two research instruments: lecturers' questionnaires and deans of schools and departmental heads' interview guides. Data were analyzed using mixed methods involving qualitative and quantitative techniques. The study revealed that most of the respondents disagreed that there were adequate human resources, which affected the quality of education at selected private universities in Kenya. Further, there was a significant positive correlation between the management of human resources and the quality of education in private universities. The study recommends that the management of private universities must prioritize recruiting additional lecturers, remunerating lecturers competitively, and implementing motivational strategies, which are crucial for fostering a conducive work environment and enhancing human resources' satisfaction.

Authors: Patang.
Published: September 2024

The aim of this research was to determine the effect of using maggot meal as a substitute for fish meal in feed on the growth and survival of tilapia (Oreochromis niloticus). This research design used a completely randomized design with 3 treatments and 1 control. Each treatment was repeated three times so that the number of experiments was 12 units, namely treatment A fish flour 45%, Maggot Flour 35%, Corn flour 16% and Tapioca flour 4%. Treatment B fish flour 50%, Maggot Flour 30%, Corn flour 16% and Tapioca flour 4%. Treatment C fish flour 55%, Maggot Flour 25%, Corn flour 16% and Tapioca flour 4%. Treatment K fish flour 0%, Maggot Flour 80%, Corn flour 16% and Tapioca flour 4%. The research results show average absolute weight growth; although the treatment with the highest weight growth was treatment K, the difference was very small compared to treatment C, which was a substitute for maggot flour with the highest dose. However, if we look at the average absolute length growth, it can be seen that treatment C shows the highest value. Survival in this study is still very high because it is above 96%; however, the FCR in all treatments was still too high because it was above 3. In terms of water quality, such as temperature, pH and dissolved oxygen, all treatments still met the needs of tilapia to live and grow.
