Seismic Analysis of Conventional, Braced, and Shell, Elevated Water Tanks for Different Seismic Zones
Authors: Singh Chukesh , Dwivedi Dr. A. K.
Published: August 2023

Abstract: Water is stored in the tanks and then distributed through the public water supply systems. The term "overhead water tanks" (OWT) or "elevated water tanks" (EWT) refers to water tanks that are constructed at a specific height. A large mass that is concentrated at the top of the EWT is supported by thin supports. The horizontal stresses brought on by earthquakes affect it severely. The elevated water tanks all around the world either collapsed or experienced major damage as a result of the earthquake since the supporting mechanisms were either poorly constructed or selected. Different structural methods and materials have been employed by a number of researchers and designers to create safe designs that keep the EWT stable during earthquakes. The current study's objective is to analyze the conventional, braced (diagonal and cross), and shell-stagging EWT for seismic zones III and IV. For that purpose, the lateral displacement and base shear of conventional, braced (diagonal and cross), and shell-stagging elevated Intze tanks have been investigated and compared. The current study also illustrates how zones III and IV are affected by full and empty EWT situations. The shell EWT has performed better than conventional EWT when lateral displacement and base shear are compared.

Published: August 2023

Abstract: The use of solar cooking can help cut back on the consumption of fossil fuels. Due to the rising expense of fossil fuels, there is a great demand for an energy efficient and affordable solar cooking technology, and it is currently the most popular study topic worldwide. This study examines how a thermal energy storage material (Erythritol) can improve the thermal performance of solar parabolic dish cookers. On the cooking vessel with and without thermal energy storage material, tests for stagnation temperature and water boiling and cooling are performed. In terms of thermal performance, heat loss factor, optical efficiency experimental results for the two instances are analysed. Heat loss factor was found to be 16.8 W/m2K and 28.21 W/m2K in with and without thermal energy storage system
Ancient Embryological Wisdom - A Scientific Explanation in the Light of Epigenetics
Authors: Sharma Dr. Khushboo , Lakhiwal Dr. Pooja , Sharma Prof. Mahendra , Gehlot Dr. Amit
Published: August 2023

Abstract: Ayurveda primarily deals with both healthy and diseased human conditions, from conception to death. Suprajanan (Healthy Progeny) is the primary goal of Garbhasharir (embryology) as described in Ayurvedic texts. Modern embryology describes in detail the formation, development, and structural teratogenesity of our body's organs, whereas Ayurveda describes the foetus' structural, physical, and mental status. There are numerous references to Garbhasharir that are quoted in Brihattrayee (the three major Ayurvedic compendia) and their commentaries that need to be elucidated in an appropriate way to make them relevant for the modern era. The current critical appraisal is based on Grabhasharir concepts mentioned in Ayurvedic lexicons in relation to embryological concepts, to interpret and analyze processes related to progeny genesis using current scientific knowledge. Brihattrayee and other relevant literature were critically reviewed to uncover the hidden core of embryology described in Garbhasharir chapters. The fundamentals of Ayurvedic embryology are 'Tridosha' (three bodily humours), 'Triguna' (three psychological humours), and 'Panchamahabhoota', among others. Ayurvedic compendia roughly depict two types of processes (dependent & independent) related to progeny genesis. Dependent processes are those that can be modified, whereas independent processes are those that cannot be modified by parental effort. Even though the embryology concepts described in Ayurveda date back centuries, they are still relevant in today's scientific world if proper insight is used to interpret them
Canada: A Pathfinder in Search of a Path
Authors: Durrant Joan
Published: August 2023

The six papers in this special issue provide a context for understanding the rationale for law reform to fully protect children from corporal punishment. As a Pathfinding Country for the UN Global Partnership to End Violence against Children, Canada has an obligation to remove Section 43 of the Criminal Code, the defence that “justifies” corporal punishment of children. As fellow nations influenced by the English common law underlying that defence, Ireland, Scotland and Wales provide models for Canada.  They demonstrate that the arguments that commonly derail repeal in Canada can be overcome.
The business strategy of the utility token adoption by investors in a developing country
Authors: Chutipat Veraphong , Sonsuphap Rattaphong , Thetlek Ruangchan
Published: August 2023

Utility tokens, which are cryptocurrencies on a smart contract blockchain that serve a specific purpose within the ecosystem of a crypto project (Shirole et al., 2020), have exploded in popularity among Thai investors over the past few years due to the fact that their value tends to increase much more rapidly than that of traditional assets. This study attempts to analyse the variables influencing Thai investors’ adoption of utility tokens. A binary logistic regression was conducted to find factors of statistical significance. The results indicate that gender, level of education, income, savings, the types of financial instruments an investor owns, and the investor’s use of social media platforms are significant determinants of utility token adoption. The article argues that when planning marketing efforts, organisations issuing utility tokens should consider their clients’ gender, level of education, income, and savings, as these factors have a substantial influence on utility token adoption. In addition, in order to increase the adoption of utility tokens by experienced investors, brokers or financial advisors must evaluate the customer’s current financial holdings in order to develop successful financial plans and provide appropriate guidance to customers.
Covid 19, Inequality and Poverty in Rural Indonesia
Authors: Sjaf Sofyan
Published: August 2023

The Covid-19 pandemic has had an impact on inequality and poverty in rural Indonesia. This study aims to identify inequality and poverty during the Covid-19 pandemic, as well as program policies for poor families after the Covid-19 pandemic in rural Indonesia. The combination of quantitative and qualitative methods with the Drone Participatory Mapping (DPM) approach is the preferred method used by researchers to obtain Precision Village Data (PVD). From this data, the researcher used the Lorenz Curve to determine the inequality and poverty of families in three villages (Sibandang, Cikarawang and Tegallalang). The results showed that the three research villages were in low inequality conditions (Sibandang Village with the typology of plantation village = 0.39; Cikarawang Village with the typology of food crops village = 0.36; and Tegallalang Village with the typology of rice field village = 0.35) during the Covid-19 pandemic. From this inequality, every poor family in rural Indonesia has a different income. Therefore, the policy to restore the condition of poor families in rural Indonesia must address three main aspects: education, employment and income.
Output feedback control for uncertain fractional-order system subject to deception cyber-attacks via observer-based event-triggered scheme 1
Authors: Ali Syed , Tajudeen M. Mubeen , Rajchakit G. , Perumal R. , Priya Bandana
Published: August 2023

This article investigates the problem of output feedback control for
fractional-order (0 1) uncertain systems subject to deception
attacks based on observer-based event-triggered scheme. Compared to the
existing deception attacks, the proposed model consists of two random
deception attacks on the fractional-order system. To decrease
communication resource usage while maintaining desired system
performance, an observer-based event-triggered scheme has been proposed.
But it also has no Zeno behavior. The Lyapunov functional theory is used
to establish sufficient conditions for ensuring the global asymptotic
stability of an uncertain fractional-order system. By generalized
applying singular value decomposition matrix, linear matrix inequalities
(LMIs), we obtained the observer, and controller gain matrices. Finally,
DC-DC power converter model is used to demonstrate the efficiency of the
proposed methodology.
Skew geometric mean constants in Banach spaces
Authors: Ni Qichuan , Liu Qi , Zhou Yin
Published: August 2023

In this paper, a new skew geometric mean constant is introduced first,
and then another new constant is introduced after restricting the
isosceles orthogonal condition. These constants are used to characterize
Hilbert spaces. Some basic properties of these constants in Banach
spaces are derived, and the values of constants in specific spaces are
calculated. On this basis, the relationship between the new geometric
constants and other famous constants is studied. Finally, based on these
identities, the relationship between the new geometric constants and the
geometrical properties in Banach spaces is discussed, such as uniform
non-square and normal structure.
Divergent Proteomic Profiles of Opium Poppy Cultivars
Authors: Aykanat Setenay , Turktas Mine
Published: August 2023

We examined the proteomic profiles of three registered opium poppy
cultivars having different alkaloid content. The study was conducted on
both stem and capsule organs. A high number of DEPs were identified
between the cultivars and the organs. We analyzed DEPs for their
contribution in GO terms and KEGG pathways. The up-regulated DEGs were
significantly enriched in photosynthesis and translation for
morphine-rich and noscapine-rich cultivars, respectively. The data
depicted that photosynthesis is crutial for BIA biosynthesis, but
different processes are also effective on morphine and noscapine
biosynthesis which occur at different branches in the biosynthetic
pathway. The protomic profiles revealed that energy demand is more
effective in morphine biosynthesis, while translational control have
leading role in noscapine biosynthesis. This is the first report
demonstrating the organ-based and cultivar-based protein expression
differences in mature poppy plant.

Skills Required to Succeed in Public Accounting: Perceptions of Black and White Accountants
Authors: Dey R. Mithu , Lim Lucy , Dickins Denise , Quamina Lesia
Published: August 2023

SYNOPSIS

We explore an understudied impact of race in public accounting careers: differences in perceptions of the skills necessary to succeed. Based on data collected from surveys of approximately 1,400 public accountants, we find that although the skills perceived as necessary to succeed are the same for all accountants (i.e., technical and interpersonal, practice development, social interactions, and academic achievement), practice development and social interactions are perceived as significantly more important to Black accountants. These perceptions are likely impacted by the underrepresentation of Black accountants in their firms and at their clients, which may result in fewer opportunities to acquire or improve these skills. Technical skills can be learned without the direct assistance of others, but learning practice development skills and social interactions require the support of others. Recommendations collected from the study’s participants to help advance the practice development and social interaction skills of Black accountants are included.
Automation Bias and the “Goldilocks Effect” in Auditing Blockchain
Authors: Campbell Cory A. , Ramamoorti Sridhar , Calderon Thomas G.
Published: August 2023

Blockchain technology appears to have unique characteristics such as inherent trust, immutability, transparency, and tighter security that might facilitate the audit process. Using a survey of AICPA members, we examine responses to the evaluation of audit evidence related to management assertions in a blockchain-enabled environment. We posit three possible effects pertaining to reliance on audit evidence in blockchain-enabled environments: (1) Goldilocks Effect (no automation bias) or the ideal scenario where auditors exhibit “just right” levels of professional skepticism and due care resulting in an optimal level of auditing; (2) Halo Effect or positive automation bias, which potentially results in over-reliance on evidence and, in turn, underauditing and; (3) Hype Effect or negative automation bias, which potentially results in under-reliance on evidence and, in turn, overauditing. Our results suggest that respondents to our survey are predominantly influenced by the Halo Effect, indicating a propensity for positive automation bias across management assertions.
Enhanced Compensation Disclosure and Ex Post Discretionary Adjustments of Realized Performance in Executive Incentive Contracts
Authors: Kim Sunyoung , Shin Jae Yong
Published: August 2023

Recent research shows that the United States Securities and Exchange Commission’s enhanced compensation disclosures introduced in 2006 reduced boards’ flexibility in their compensation decisions and that boards immediately reacted by increasing executive pay to compensate for additional pay risk. We investigate firms’ longer-term reactions to these new disclosure rules. We find that firms often adjust realized earnings per share ex post when deciding their executives’ bonuses, and this practice has gained popularity since 2006. The use of ex post discretionary adjustments is more pronounced when boards’ demand for compensation flexibility is higher. Overall, our findings suggest that ex post discretionary adjustments are a source of flexibility that boards use to cope with limited compensation flexibility under the new compensation discussion and analysis disclosure rules.

The Effects of Span of Control and Temporal Disaggregation of Performance Reports on Discretionary Performance Evaluations
Authors: Ghita Razvan S. , Maas Victor S.
Published: August 2023

Span of control and temporal disaggregation of performance reports are two important control system elements that jointly determine the benchmarks that managers have available when evaluating employees’ performance. Using an experiment, we investigate whether widening managers’ span of control and temporally disaggregating performance reports affect managers’ evaluation decisions. We predict and find that managers with a wider span of control evaluate their best performing employees more favorably and their worst performing employees less favorably. We also find that disaggregating performance reports, i.e., providing quarterly performance figures in addition to annual performance figures, has a negative effect on managers’ evaluations of their best performing employees, but only when their span of control is wide. We discuss the implications of our findings for management accounting research and practice.

Connectors: A Catalyst for Team Creativity
Authors: Autrey Romana L. , Drasgow Fritz , Jackson Kevin E. , Klevsky Elena
Published: August 2023

Creativity drives profit in an idea economy, and many companies organize teams to facilitate creativity. This paper investigates the strategic deployment of individuals to boost a team’s creativity. More individualistic team members tend to generate highly original ideas yet are less likely to share these ideas. We theorize that adding a connector—an individual strongly predisposed to form and foster relationships—to a team will enable more idea sharing among individualistic team members, thus increasing the likelihood that the team’s creative potential will be realized. We leverage a new conceptualization of the “connector” construct to identify connectors and then use an experiment to study the impact of their presence or absence on team creative performance. Our results support these predictions and suggest that connectors improve team creativity by enabling others to share in the creative process and not because connectors themselves exhibit greater creative performance than their average peer.

Subject Matter Complexity and Disclosure Channel Richness
Authors: Skinner A. Nicole
Published: August 2023

Despite the increase in and diversity of disclosure channels available, our understanding of how managers incorporate channel features into their disclosure decisions remains incomplete. I provide evidence that managers choose relatively rich channels that offer multiple cues, opportunities for interaction, and linguistic diversity (i.e., the earnings call, as compared to the press release) to communicate complex information. The positive relation between disclosure channel richness and subject matter complexity persists in both a document-level analysis and a small sample test examining disclosure channel choice from all possible disclosure channels. I provide some evidence that deviating from the complexity/richness matching strategy is associated with a muted market response to firms’ quarterly disclosures. The results are consistent with managers choosing disclosure channels to reduce investors’ information processing costs.

Authors: Widayani Prima , Fadilah Achmad , Irawan Irfan Zaki , Ghosh Kapil
Published: August 2023

Slums are one of the urban problems that continue to get the attention of the government and the city of Yogyakarta. Over time, cities continue to experience changes in land use due to population growth and migration. Therefore, it is necessary to monitor the existence of slums continuously. The objectives of this study are to conduct early identification of the slum using the Support Vector Machine (SVM) Algorithm, which is applied to the Pleiades Image in parts of Yogyakarta City, to test the accuracy of the slum mapping results generated from the SVM compared to the Slum Map of the KOTAKU Program. The data used are Pleiades Image, administrative maps, and existing slum maps of the KOTAKU Program, which are used to test the accuracy. The method used is Machine Learning with a Support Vector Machine Algorithm. The parameters used for early identification of the slums are the characteristics of the object (characteristics of buildings), settlement (density and shape), and the environment (location and its proximity to rivers and industries). We separate slum and non-slum based on texture, morphology, and spectral approaches. Based on the accuracy test results between the SVM classification results map of the slum and the map from the KOTAKU Program, the accuracy is 86.25% with a kappa coefficient of 0.796.

Authors: Medayese Samuel , Magidimisha-Chipungu Hangwelani Hope , Chipungu Lovemore
Published: August 2023

Rapid urbanisation in African cities has caused considerable problems by hindering their ability to meet infrastructure and service needs, resulting in rising land-use consumption. This study examines how land use/land cover change in Lafia, a city in North-central Nigeria, has impacted the city's boundaries between 1999 and 2019 and includes a projection using GIS simulation of land use/ land cover to 2029. The methodology includes remote sensing techniques, spatiotemporal analysis of geographical measurements, and statistical models. This study involved spatial analysis and projection of city growth from 1999 to 2029 in Lafia using GIS. This analysis focuses on the changes in built-up areas, vegetal cover, bare land, and water bodies using land-use/landcover data. The results indicated significant urban expansion and its impact on the city's spatial patterns. The Urban Expansion Differentiation Index (UEDI) and Urban Expansion Intensity Index (UEII)were used to assess urban sprawl and socioeconomic patterns such as population density and density gradient. High residential and employment densities, varied land uses, continuous development, and multi-modal transportation are all important for sustainable urban growth. The study indicates a direct relationship between population growth and urban expansion, as seen in Lafia. Furthermore, the findings suggest that cities grow beyond their typical boundaries, resulting in peri-urban expansion, as shown in the Alakio districts of the Lafia Metropolis. The study findings have important implications for urban growth policy and land use/land cover change. They will contribute to a better understanding of the effects of urban growth on the spatial matrix and morphology of cities, assisting city planners in recognizing these effects. Furthermore, the study adds evidence to the continuing debate about urban expansion, liveability, and spatial sustainability in African cities. The thorough examination of land use/land cover change in Lafia sheds light on the spatial dynamics of urbanisation and its implications for sustainable urban development.

Published: August 2023

The research described here was conducted at the Tangkolak Marine Center (TMC) tourist attraction in Cilamaya Wetan District, Karawang Regency, Indonesia in November and December 2019. This research aimed to analyze the suitability of the mangrove tourism area using PlanetScope sensor Dove-R satellite imagery. The research method consisted of literature review, observation, calculation of the NDVI (Normalized Difference Vegetation Index) formula using PlanetScope sensor Dove-R satellite imagery, and direct measurements of transects and sample plots. The variables used were thickness, density, mangrove types, biota objects, tides, area characteristics, and accessibility. The results showed that mangrove tourism in TMC could be classified into two categories: suitable (65%-80%) and conditionally-compliant. According to the classification, the area is characterized by a mangrove thickness of up to 175.0 meters, a mangrove density between 15-25 tree/100 m2, 3-5 types of mangrove species, and associated biota including mudskipper fish, shrimp, crab, and crane. Meanwhile, the other area classified as conditionally compliant is characterized by a thickness of up to 48.2 meters, a mangrove density of 5-10 tree/100 m2, 2 species of mangrove, and associated biota in the form of mudskipper fish, shrimp, and crab. The research highlights the successful application of remote sensing data, specifically PlanetScope satellite imagery, for studying mangrove tourism areas, indicating its potential as a valuable alternative data source for such investigations.

Published: August 2023

Maninjau Lake is one of Indonesia's lakes for hydroelectric power plants, tourism, and fish farming activities. Some activities around the lake cause pollution, leading to massive fish kill. Therefore, it is necessary to monitor water quality regularly. One of the critical water quality parameters is biochemical oxygen demand (BOD). This study aimed to analyze BOD changes using a remote sensing approach during massive fish kills in Maninjau Lake, Indonesia. Multi-temporal Landsat-8 satellite images are processed to estimate the BOD level based on Wang Algorithm. After that, the estimated BOD value is validated using in situ data measurement. The results of the average BOD concentration that occurred in Lake Maninjau was 1.85 mg/L and showed that R2 was 0.8334, and the standard error was 0.076 between the estimated BOD and in situ data. Furthermore, the average concentration of BOD obtained on 23rd August 2017, 13th December 2017, 30th January 2018, 19th March 2018, and 7th July 2018 are 4.96 mg/L, 4.82 mg/L, 5.31 mg/L, 6.94 mg/L, and 6.60 mg/L, respectively. Increased BOD concentration in January 2018 indicates moderate pollution in the waters. BOD concentration increases after the massive fish kill due to the decaying fish across the lake.
The Peri-Urban Gentrification Process in Cisauk Subdistrict, Tangerang Regency, Indonesia
Authors: Andini Myla Dyan , Lestari Forina , Medtry M , Karenina Anna
Published: August 2023

Gentrification is a phenomenon that occurs in many regions. Gentrification is characterized by the influx of more affluent residents into initially low-value areas. This influx increases the value of these areas, potentially leading to the displacement of people who cannot afford to remain in the neighborhood. This study aims to examine the cause and impacts of peri-urban gentrification in Cisauk District, Tangerang Regency. This study uses qualitative and remote sensing-based analysis to investigate gentrification's impact on six Cisauk sub-district villages. We used primary and secondary data for the analysis. The primary data was collected from observations, interviews, questionnaires, and Google Earth Engine data catalog to get Landsat 7 and 8 image-ries. The secondary was collected from the Central Bureau of Statistics. The Landsat data was used to identi-fy the change on the physical aspect, while the others were used to analyze the non-physical aspect. After-ward, positive and negative effects were explored, emphasizing residents' responses and adaptations. The re-sults showed that Cisauk Subdistrict faced a gentrification process driven by locational factors (i.e., proximity to toll road) and local government policies (i.e., spatial planning policy designating it as a high-density residential area). The positive impact of the gentrified area is that the region is developing economically much better, and many areas function better economically and so benefit the region and its people. On the other hand, the negative impacts of gentrified areas are that indigenous people are threatened with being forced to leave their villages, there are significant increases in land prices, and changes in people's social lives occur. To minimize the negative impact of gentrification, the government should promote the capacity of low-income households to access its benefits.

Based on the results of the research, it can be concluded that the implementation of SNM can improve the learning outcomes in GCD and LCM. But the student’s activeness does not affect learning outcomes because the student has been active since the beginning of the lesson.

More and more academic journals are using social media these days. Social media activity requires planning, and the effectiveness of attracting the target audience depends on how well the content is selected. This paper discusses how to develop a content plan for a social networking scientific journal. The basic concepts are disclosed: content, content plan, target audience, tangible and intangible actions of the target audience. The results of a sociological survey of potential target audience of scientific journal are given. The majority of survey participants indicated that they would like to see the content of the social network of a scientific journal to be more diverse and attractive. To increase diversity and attractiveness it is proposed to divide the content in the social network of a scientific journal according to three objectives: to broadcast the values of the journal, to demonstrate the expertise of the editorial board, to sell the services of the journal. With the proposed content builder, scientific journal editors can start and maintain a successful social media campaign and effectively engage with the target audience.

It is vital for educators to understand and match the learning needs of every student for learning to take place effectively. A detailed reference of the students’ entry characteristics, family background, and previous academic performance is useful in determining the materials and activities to be used with the students. The respondents of this study involved 103 students who enrolled in the pre-higher education programme. The characteristics to identify at-risk students are used as guidelines to redefine the definition of pre-higher education students. Therefore, the study aims to examine the characteristics of pre-higher education students based on their academic performance and socio-economic status. A quantitative method is used to gather more information about the basic entry characteristics, previous academic achievement, family background and Sijil Pelajaran Malaysia (SPM) results of the students. The findings of the study help the researcher to define the terminology of the pre-higher education programme. Having to confirm to the conceptual definition of the pre-higher education students helps the policy makers and institutions to develop a suitable learning programme to cater to their learning needs.
