Published: July 2023

The recent discovery of enormous Lyα nebulae (ELANe), characterized by physical extents >200 kpc and Lyα luminosities >1044 erg s−1, provides a unique opportunity to study the intergalactic medium and circumgalactic medium in distant galaxies. Many existing ELANe detections are associated with local overdensities of active galactic nuclei (AGN). We have initiated a search for ELANe around regions containing pairs of quasi-stellar objects (QSOs) using the Palomar Cosmic Web Imager. The first study of this search, Cai et al., presented results of ELAN0101+0201, which was associated with a QSO pair at z = 2.45. In this study, all targets residing in QSO pair environments analyzed have Lyα detections, but only one of the four targets meets the classification criteria of an ELANe associated with a QSO pair region (z ∼ 2.87). The other three sample detections of Lyα nebulae do not meet the size and luminosity criteria to be classified as ELANe. We find kinematic evidence that the ELANe J1613 is possibly powered mostly by AGN outflows. The analysis of circularly averaged surface brightness profiles of emission from the Lyα regions shows that the Lyα emission around z ∼ 2 QSO pairs is consistent with emission around individual QSOs at z ∼ 2, which is fainter than that around z ∼ 3 QSOs. A larger sample of Lyα at z ∼ 2 will be needed to determine if there is evidence of redshift evolution when compared to nebular emissions at z ∼ 3 from other studies.
Not So Fast, Not So Furious: Just Magnetic

Published: July 2023

WD 0810-353 is a white dwarf within the 20 pc volume around the Sun. Using Gaia astrometric distance and proper motions, and a radial velocity derived from Gaia spectroscopy, it has been predicted that this star will pass within 1 pc of the solar system in about 30 kyr. However, WD 0810-353 has been also shown to host a magnetic field with a strength of the order of 30 MG. Its spectrum is therefore not like those of normal DA stars of similar effective temperature. We have obtained and analyzed new polarized spectra of the star around Hα. Our analysis suggests that the visible surface of the star shows two regions of different field strength (∼30 and ∼45 MG, respectively), and opposite polarity. The spectra do not change over a 4 yr time span, meaning that either the stellar rotation period is no shorter than several decades, or that the field is symmetric about the rotation axis. Taking into account magnetic shift and splitting, we obtain an estimate of the radial velocity of the star (+83 ± 140 km s−1); we reject both the value and the claimed precision deduced from the Gaia DR3 spectroscopy (−373.7 ± 8.2 km s−1), and we conclude that there will probably be no close encounter between the solar system and WD 0810-353. We also reject the suggestion that the star is a hypervelocity runaway star, a survivor of a Type Ia supernova explosion. It is just a stellar remnant in the solar neighborhood with a very strong and complex magnetic field.
Intelligent Vision Based Decision Making System for Aviation Accidents and Incidents
Authors: Lamba Monika , Verma Seema , Kumar Pardeep
Published: July 2023

Safety has become the primary concern for the air transportation system nowadays primarily due to increasing air traffic throughout the world. Various regulatory bodies have been maintaining enormous amount of aviation accidental data repositories. This past data is highly complex because of its many temporal and geographical components along with multiple variables. To be able to analyze this past data, there is always a need of user friendly and GUI based System. This article has proposed an intelligent vision-based decision-making system for the exploration of past aviation accidents and incidents dataset. The proposed visual query-based model is capable to analyse the major factors like flight phases, human factors, weather conditions and faulty components in particular aircraft models which are responsible for those unsafe events and may claim life of many passengers who are traveling and crew personnels. This model enables the users to express “what” visuals should be created instead of “how” to create them. Various case studies conducted through visual queries have proved that the system will be highly able to improve situational awareness regarding flight conditions to the crew members and air traffic controllers along with aviation authorities so that they are able to take timely decisions and deciding on what kind of training staff members need to reduce the consequences of such accidents and incidents.
Aligning Interactive Multimedia Development Practices With Mayer's Split-Attention Effect Principle
Authors: Rajabalee Yousra Banoor
Published: July 2023

Multimedia learning can be defined as the construction of knowledge based on instructions that are delivered through the combined use of visuals such as text, images, animations, etc. It is best described by Richard Mayer, one of the leading researchers in this area who postulated that people learn better from words and pictures than from words alone. Multimedia instructions have for objectives to enhance and promote meaningful learning. The split-attention effect occurs when multimedia instruction is designed in a way that it requires learners to split their attention between, and mentally integrate multiple sources of information that are separate in temporal or physical dimensions/locations. Mayer's principles are guiding constructs, useful for creating effective interactive multimedia materials. This chapter elaborates and sheds light on how to creatively design or develop multimedia learning materials, which can create constructive knowledge by sustaining good engagement in learning and by overcoming and managing the split-attention problems.
The Relationship Between Index of Sustainable Economic Welfare and Renewable Energy Production in Turkey
Authors: Coşkun Muhammet Fatih , Konat Gökhan
Published: July 2023

ISEW (Index of Sustainable Economic Welfare), one of the important indicators of sustainable development, is an important tool that should be measured regularly and its relationship with other macroeconomic indicators should be closely monitored. In this context, the current calculation of ISEW in the Turkish economy and the analysis of its relations with renewable energy generation constitutes the purpose of this study. As a result of the econometric tests, it is found that there is a long-term relationship between the two variables considered according to the RALS-EG cointegration test. The long-term coefficient estimation of the co-integrated variables has been estimated by the dynamic OLS (DOLS) method, and it is seen that renewable energy production has a negative effect on sustainable development. This result differs from the majority of studies on developed countries. Theory and literature say that renewable energy will support sustainable development.
Is the Tourism-Induced Environmental Kuznets Curve Hypothesis Valid in the Most Visited Countries?
Authors: Hacıimamoğlu Tunahan
Published: July 2023

This study aims to test the tourism-induced EKC hypothesis, which claims the existence of an inverted U-shaped relationship between environmental pollution and tourism activities, for the period 1995-2018 in the most-visited countries in terms of the number of international tourists (Spain, United States, China, Italy, Turkey, Mexico, Thailand, Germany, and England). In this study, in which ecological footprint, which is a comprehensive and alternative variable, was used as an indicator of environmental pollution, the relations between the variables were analyzed using second-generation test techniques. Long-term relationships were examined by the LM and DH test, and the coefficients were estimated with the common correlated effects mean group (CCE–MG) and dynamic common correlated effects (DCCE) estimators. As a result of the empirical analysis, it was found that there is a U-shaped relationship between environmental pollution and tourism activity, and the validity of the tourism-induced EKC hypothesis could not be confirmed.
Convergence in Environmental-Related Technologies Across OECD Countries
Authors: Ursavaş Uğur
Published: July 2023

This study investigates the convergence process of environmental-related technologies patents over the period 1991-2019 across 36 OECD countries. To do so, the club convergence methodology of Phillips and Sul is used, which allows the authors to analyze overall convergence and identify possible convergence clubs. The log-t test results show that OECD countries do not converge to the same equilibrium point in terms of environmental-related technologies patents per capita. However, the club clustering algorithm shows that while 33 OECD countries converge to a common point, Hungary, South Korea, and Lithuania are diverging countries.

Authors: Malik Sahil , Dhaliwal Amandeep , Hazarika Deepti Dabas
Published: July 2023

The existence of a formal university system of education in India has been from the days of Nalanda and the likes of Taxila, Vikramashila, which proves that India was well ahead of its time in the field of education. The Nalanda University rose to prominence with scholars and students from Central and Southeast Asia till the last years of the 12th century after which it was destroyed by rulers of that time. The existence of Nalanda University has laid the foundation for the modern concept of university-level education uplifting the level of literacy and shedding the darkness of ignorance of the then civilization. The chapter examines the scope of bettering the state of higher educational institutions in India and the world in their endeavor to become centers of excellence. The chapter also examines the advantages of leveraging word of mouth, which could help the institutions build on their brands and improve upon their rankings.

Authors: Ajonbadi Hakeem Adeniyi , Adekoya Olatunji David , Mojeed-Sanni Bashir , Olawoyin Femi Stephen
Published: July 2023

This chapter reports on the findings of the study undertaken to explore the relationship between transformational leadership and transformational teaching/learning in the Kuwaiti context. Using interpretivism and qualitative research methods, this study relies on 21 in-depth interviews, which comprise a range of academics at different levels. The interviewees were academics who have experienced the varying nature of heads of departments' (HoDs') leadership behaviour, which has impacted their motivation, engagement, commitment, and personal satisfaction/growth and in turn affected transformational teaching. In addition to prior identified transformational leadership impacts, four themes emerged that explain the impacts that HoDs' leadership style has on academics and students' learning, development, and outcome. This study found that transformational leadership positively impacts transformational teaching and learning. The study implies that transformational leadership correlates with transformational teaching that enables academics and students to learn, develop, and be motivated.
Now What?
Authors: Crawford Caroline M.
Published: July 2023

After surviving 25 years in academia, one faculty member questions whether being the target of nefarious queen bees is worth the career impact, state of one's mental well-being, and bearing upon one's quality of life. After initiating an academic career as a novice assistant professor, attaining tenure and promotion to associate professor, and ultimately achieving promotion to professor, the case study focuses upon the faculty member's questions around relevancy and whether the impact of queen bees upon the creation of a toxic work environment is worth remaining in a situation that chips away at one's academic triad passions of teaching, research, and service. This case study will focus upon aspects of academia that are directly impacted by queen bees, sharing narrative understandings and experiences through a storytelling that takes on a Currere Method style of engagement in what may be described as a complex, difficult conversation.

Surviving the Hive in Global Crisis?
Authors: Hayes Catherine
Published: July 2023

The metaphorical concept of the ‘Queen Bee' now transcends situational contexts to such an extent that it has become a universal focus for both contexts of research and professional practice. Global crises provide a unique context of perspective for the manifestations of gender inequity to be revealed within the context of leadership and management in higher education. From a historical perspective, a woman whose behaviours were identifiable as being characteristic of a Queen Bee became associated with the notion of projected enmity towards others, typically younger women who may be able to compete with them professionally. Whether or not misogyny in predominantly male-oriented professions has contributed to the need for women to compete in this manner remains an issue of contention, especially in workplace settings where there have been issues of gender inequity in relation to leadership capacity. This chapter illuminates aspects of Queen Bee complex through a lens of perspective which permits a metacognitive consideration of gender-based standpoints in higher education.

Science Diplomacy for Renewable Energy
Authors: Lamsiah Abdelmajid
Published: July 2023

Science's role as a tool for international coordination, collaboration, and tact has contributed to the major successes of the global pandemic response. Scientists and politicians have agreed on the “same” interpretation and significance of evidence, and that science is by far a strong institution that may be the root of all types of dissonance. The three countries under consideration are gradually forming a vision toward leveraging science diplomacy and establishing practices in which participation in the diplomatic aspect of science is key to dynamics of strategic interests. By concentrating primarily on diplomatic tactics employed in international business and undertaking an examination of renewable energy policy, the study offers a humble comparison. The research's scope may be limited by the tight-lipped approach with which the three African countries handle their economic interests—an approach that is linked and roped in by the way diplomacy and science are essentially intermingled.

In this chapter, the authors discuss the previously existing distrust of science that was exacerbated during the Trump presidency. Included are a description of how science distrust and anti-intellectualism began in the 1960s and further escalated over time, resulting in the politicization of science. Science/scientist and intellectual trust level differences are readily apparent between conservatives and liberals, with liberals demonstrating significantly higher levels of trust in science/scientists and intellectualism than conservatives. Also discussed is the impact the Trump presidency had on this partisan divide concerning science trust in general and climate science, COVID-19 science, and vaccination science trust in particular. The chapter culminates with suggestions for strategies related to counteracting the polarization and rebuilding science trust.
Integrating E-Learning and Digital Literacy Into Module Content and Delivery in Higher Education
Authors: Atta Zainab
Published: July 2023

This chapter discusses how the top-down approach to embedding digital literacy within universities and higher education institutes (HEIs) contributes to the lack of digital literacy, digital competency, and digital proficiency embedded within modules in university programmes. This it is suggested is related to the lack of integration between the key stakeholders (students, academics, and educational technologists). The nature of digital gaps are suggested, and an approach which builds from the operational level up towards the strategic is suggested. An example using a marketing module at first year of a degree programme is given. This approach should assist in designing-in digital literacy into modules.

The Evolution of Waste Bank in Indonesia
Authors: Musari Khairunnisa
Published: July 2023

Along with the call towards a climate-neutral economy, one solution that has in recent years become popular is the circular economy. Indonesia has local wisdom, which is a form of circular economy, namely 'waste bank.' The waste bank is a practice of social engineering that encourages people to sort waste from its source so that it can generate economic value. Besides preserving the environment, the waste bank in Indonesia also helps to increase financial inclusion through nano finance for its customers. Through literature studies, observations or field studies, interviews, and using nethnography, this study aims to describe the evolution of waste banks in Indonesia in supporting the circular economy. This study found that waste banking brings not only implications for economy and environment, but also brings implication for social and religious value at the same time. Nano finance in the waste bank is similar to qard al-hasan. In Islamic finance, qard al-hasan is a kindness loan that is recommended as the most appropriate contract to be implemented in ultra-micro community groups.

Published: July 2023

The exact solution of the Feinberg-Horodecki equation for time-dependent harmonic vector potential has been investigated under a one-dimensional system. The quantized momentum and its corresponding un-normalized wave functions were explicitly obtained. The Fisher information (for time and momentum) and variance (for time and momentum) were calculated using expectation values of time and momentum via Hellman-Feynman Theory (HFT). The time and momentum Shannon entropy were obtained using an existing formula. Numerical results were for time and momentum Fisher information to confirm the Cramer-Rao inequality. Another numerical results were obtained for time and momentum Shannon entropy to confirm Bialynick-Birula, Mycielski (BBM) inequality. The effects of the potential parameters such as mass of the spring and the frequency on the theoretic quantities were fully examined. The new variance inequality was established using the inequalities of Fisher information. The established inequality was confirmed by numerical results which also satisfied the popular Cramer-Rao inequality. The theoretic impetuses for Fisher information, variance and Shannon entropy respectively, were calculated and their variation with some potentials were studied.

The Great Resignation, or the Big Quit, shook the world of work, leaving it questionable whether organizations could find and retain the necessary talents. Nevertheless, the shrinking Transition to Entrepreneurship (TE) demonstrated that developing countries were less affected by this massive attrition wave. However, in the context of developing countries, the causes of thinner TE remain unknown. The current study investigated the perceived barriers to TE in the Sri Lankan context. The present study followed a quantitative approach to test the extent to which demographic, environmental, motivational, human capital, and behavioral factors are perceived as barriers to TE intention. Participants in the field survey provided the data based on a psychometric measure with a seven-point response scale. Structured Equation Modelling (SEM) analyzed the data. According to the findings, employees in Sri Lankan context are more likely to avoid transitioning from their current employment to entrepreneurship because they perceive behavioral, human capital, and demographic factors as barriers to TE. However, the prospective entrepreneurs in the Sri Lanka did not perceive motivational and environmental factors as significant barriers to TE. The implications suggest modeling TE by incorporating the identified roadblocks to TE to predict entrepreneurial penetration in developing countries.

Authors: Samaratunge D. B. N. D. , Ariyapperuma A. R. M. I.
Published: July 2023

The emergence of new skill gaps during covid-19 with the shift in working methods and procedures has emphasized more on training and development needs in upskilling and reskilling employees accordingly. However, since Covid-19 imposed much greater responsibility to governments, budget cuts on fund allocation to training and development impacted employees, especially with a growth mindset, in accordance to Carol Dweck’s incremental theory of intelligence. Accordingly, this research aims to identify the impact of such training and development interruptions on employee growth mindset. Data collection of the study is done using 5-point Likert questionnaires out of a sample consisting managerial and operational level employees of the three highest revenue generating public sector enterprises of Sri Lanka. Accordingly, the study confirms that there is a significant impact on employee growth mindsets due to training and development interruptions which was tested using the individual-level outcomes of employee growth mindset with major training and development interruptions identified by the international labor organization.

Published: July 2023

Acute pancreatitis (AP) often leads to a high incidence of cardiac injury, posing significant challenges in the treatment of severe AP and contributing to increased mortality rates. Mesenchymal stem cells (MSCs) release bioactive molecules that participate in various inflammatory diseases. Similarly, extracellular vesicles (EVs) secreted by MSCs have garnered extensive attention due to their comparable anti-inflammatory effects to MSCs and their potential to avoid risks associated with cell transplantation. Recently, the therapeutic potential of MSCs-EVs in various inflammatory diseases, including sepsis and AP, has gained increasing recognition. Although preclinical research on the utilization of MSCs-EVs in AP-induced cardiac injury is limited, several studies have demonstrated the positive effects of MSCs-EVs in regulating inflammation and immunity in sepsis-induced cardiac injury and cardiovascular diseases. Furthermore, clinical studies have been conducted on the therapeutic application of MSCs-EVs for some other diseases, wherein the contents of these EVs could be deliberately modified through prior modulation of MSCs. Consequently, we hypothesize that MSCs-EVs hold promise as a potential therapy for AP-induced cardiac injury. This paper aims to discuss this topic. However, additional research is essential to comprehensively elucidate the underlying mechanisms of MSCs-EVs in treating AP-induced cardiac injury, as well as to ascertain their safety and efficacy.

Improvement in hand hygiene has been strongly associated with positive outcomes in maternal and child health. Although Bangladesh has a high level of awareness of key hygiene messages, the practice of handwashing, the most effective hygiene behavior, is low. Suchana, a multisectoral nutrition program, aims to increase knowledge and practices around various water, sanitation, and hygiene settings in Sylhet region, the northeast of rural Bangladesh. This study aimed to investigate the changes in indicators related to handwashing knowledge and practices among Suchana beneficiaries in final compared with baseline evaluations. Data were derived from the baseline and final cross-sectional evaluation survey. The following handwashing knowledge and practices were considered: handwashing before preparing food, before eating food and feeding children, before serving food, after defecation, and after touching animals. The descriptive findings indicate that Suchana intervention improved handwashing knowledge and practices in the intervention area compared with the control. The odds of having knowledge of hand washing before preparing food (adjusted odds ratio [aOR]: 1.60; 95% CI: 1.30–1.98), before eating food and feeding children (aOR: 1.68; 95% CI: 1.25–2.25), before serving food (aOR: 1.35; 95% CI: 1.04–1.76), after defecation (aOR: 1.74; 95% CI: 1.25–2.41), and after touching animals (aOR: 1.67; 95% CI: 1.29–2.16) were higher in intervention area than the control area. Similarly, the impact on maternal handwashing practices at final evaluation indicated successful effects of the intervention. These results suggest scaling-up of similar interventions for larger populations living in vulnerable areas of rural Bangladesh.

Removal of Azo Dye (Acid Red 18) from Aqueous Solution using a Bioadsorbent from Carica Papaya Peels
Authors: Magomya A. M. , Elisha U. V.
Published: July 2023

This study evaluates the removal of Acid Red 18 (AR 18) dye from aqueous medium using an adsorbent developed from Carica papaya peel. The adsorbent was prepared by carbonization at 500oC followed by activation with NaOH solution. Moisture content, ash content and volatile matter of the adsorbent were determined to be 2.87%, 11.0% and 89.0% respectively. FTIR characterization which was done before and after activation indicated some functional group modifications. The parameters affecting sorption such as initial sorbate concentration, adsorbent dosage, contact time, temperature and pH were evaluated and average percentage removal of AR 18 by the adsorbent was found to be 70%. Correlation of the experimental data with Langmuir and Freundlich adsorption isotherms revealed linear coefficient (R2) values of 0.802 and 0.720 respectively; thus implying that the Langmuir isotherm best describes the adsorption process. Lagergren pseudo first order and pseudo second order models were employed to test the sorption kinetics and our findings indicated that the sorption of the dye followed pseudo second order kinetics.
