HISTORY OF RESEARCH OF SCYTHIAN SITES IN THE NORTHERN AZOV SEA REGION
Authors: Demina А. D.
Published: November 2023

Northern Azov region (Pryazovia) is the place of concentration of one of the largest groups of Scythian sites of the 5th—4th centuries BC. At the same time, local necropolises show significant variability in chronological and structural characteristics. Therefore, one of the first issues aimed at a better understanding of the region is the completeness and directions of archaeological research of the territory. The paper offers an overview of the main stages of the discovery of the Scythian sites in this region and the factors that influenced them. It follows the chronological order of explorations, both field and theoretical. The first excavations date back to the 19th century with the discovery of the kurhans in the Obitochna river mouth. The synchronous historical-geographical attempt of placing Herodotus’ Royal Scythians on the map of the Azov region is analyzed separately. The early 20th century is mostly characterized by archaeological studies in the local museums. The first large-scale expeditions as well as the summarizing works that approached the Azov region started in 1950—1960. During this stage the first in the 20th century Royal barrow, Melitopol kurhan, was excavated. This discovery prompted further research of the large kurhans in the Azov region. The breakthrough stage is considered to be the period between 1970 and 1990. The works in the North-Western part of Pryazovia were primarily associated with the Khersons’ka and Priazovs’ka expeditions of the Institute of Archaeology (IA). During this time, no less than 130 Scythian burial mounds were discovered and recorded there. The scope and amount of the field research also influenced the advancement in the standardization of the procedure of the kurhan exploration and documentation. In the Kalmius basin, archaeological research took place less intensively due to the smaller area of construction works. The excavations of the 1970s were primarily connected with the activities of the Donetsk expedition of the IA led by S. Bratchenko. Although the number of burials in the Donetsk region was significantly smaller, the research of the Shevchenko and Kremenivka complexes showed the presence of unique ritual sites, as well as the intensive use of local granite deposits for the construction of stone structures. Overall, more than a century of research allowed a better understanding of the history of the Scythians in the Pryazovia and showed the importance of continuing fieldwork and further conceptualizing this region.

Published: November 2023

Residual modulation of galactic cosmic rays in the heliosphere and its energy dependence are studied with data from three types of ground-based detectors, using data from PAMELA, AMS-02, and Voyager 1/2.
It is shown that the residual modulation is approximately the same in magnitude as the observed variations due to the solar activity cycle, which allows us to make some conclusions about the modulation
processes in the heliosphere.
The Cost of Equality: Analyzing the Unforeseen Financial Strains of Fee-Free Higher Education in South Africa
Authors: Yende Sakhiseni Joseph , Mthombeni Zama M.
Published: November 2023

In the past, many South African students found it difficult to pursue higher education due to the high expense of tuition, which also restricted their prospects for development on both a personal and professional level. Fee-free education has helped to level the playing field and provide equal access to education, regardless of an individual’s financial background. Evidently, financially disadvantaged students now have better access to higher education, and this is attributed to fee-free education in South Africa. However, budgetary restrictions exist in South Africa, and the government’s finances are put under strain by the country’s policy of free public education for all pupils. The purpose of this article was to discuss unforeseen financial constraints in South African higher education due to fee-free education. In this article, a qualitative content analysis was employed which was grounded on analysing the existing scholarly literary writings. This paper established that enrolment rates in universities and colleges all around South Africa have increased significantly because of fee-free education. This research adds to the continuing discourse concerning the expenses tied to achieving equality and the unanticipated financial pressures stemming from tuition-free higher education in South Africa. Keywords: Fee-Free Higher Education, Government Finances, Access To Higher Education, Funding
Fast Gravitational-wave Parameter Estimation without Compromises
Authors: Wong Kaze W. K. , Isi Maximiliano , Edwards Thomas D. P.
Published: November 2023

We present a lightweight, flexible, and high-performance framework for inferring the properties of gravitational-wave events. By combining likelihood heterodyning, automatically differentiable, and accelerator-compatible waveforms, and gradient-based Markov Chain Monte Carlo sampling enhanced by normalizing flows, we achieve full Bayesian parameter estimation for real events like GW150914 and GW170817 within a minute of sampling time. Our framework does not require pretraining or explicit reparameterizations and can be generalized to handle higher dimensional problems. We present the details of our implementation and discuss trade-offs and future developments in the context of other proposed strategies for real-time parameter estimation. Our code for running the analysis is publicly available on GitHub at https://github.com/kazewong/jim.

We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting (L/L
Edd = 0.74–3.4) active galactic nucleus, Markarian 142 (Mrk 142), for the first time using concurrent observations of the inner accretion disk and the BLR to determine a time lag for the Hβ
λ4861 emission relative to the ultraviolet (UV) continuum variations. We used continuum data taken with the Niel Gehrels Swift Observatory in the UVW2 band, and the Las Cumbres Observatory, Dan Zowada Memorial Observatory, and Liverpool Telescope in the g band, as part of the broader Mrk 142 multiwavelength monitoring campaign in 2019. We obtained new spectroscopic observations covering the Hβ broad emission line in the optical from the Gemini North Telescope and the Lijiang 2.4 m Telescope for a total of 102 epochs (over a period of 8 months) contemporaneous to the continuum data. Our primary result states a UV-to-Hβ time lag of

We placed our new measurements for Mrk 142 on the optical and UV radius–luminosity relations for NGC 5548 to understand the nature of the continuum driver. The positions of Mrk 142 on the scaling relations suggest that UV is closer to the “true” driving continuum than the optical. Furthermore, we obtain

Tidal Deformability of Neutron Stars in Scalar-tensor Theories of Gravity
Authors: Brown Stephanie M.
Published: November 2023

Gravitational waves from compact binary coalescences are valuable for testing theories of gravity in the strong field regime. By measuring neutron star tidal deformability using gravitational waves from binary neutron stars, stringent constraints were placed on the equation of state of matter at extreme densities. Tidal Love numbers in alternative theories of gravity may differ significantly from their general relativistic counterparts. Understanding exactly how the tidal Love numbers change will enable scientists to untangle physics beyond general relativity from the uncertainty in the equation of state measurement. In this work, we explicitly calculate the fully relativistic l ≥ 2 tidal Love numbers for neutron stars in scalar-tensor theories of gravitation. We use several realistic equations of state to explore how the mass, radius, and tidal deformability relations differ from those of general relativity. We find that tidal Love numbers and tidal deformabilities can differ significantly from those in general relativity in certain regimes. The electric tidal deformability can differ by ∼200%, and the magnetic tidal deformability differs by ∼300%. These deviations occur at large compactnesses (C = M/r ≳ 0.2) and vary slightly depending on the equation of state. This difference suggests that using the tidal Love numbers from general relativity could lead to significant errors in tests of general relativity using the gravitational waves from binary neutron star and neutron star black hole mergers.
High-angular-resolution Imaging of the V892 Tau Binary System: A New Circumprimary Disk Detection and Updated Orbital Constraints
Authors: Vides Christina L. , Sallum Steph , Eisner Josh , Skemer Andy , Murray-Clay Ruth
Published: November 2023

We present a direct imaging study of V892 Tau, a young Herbig Ae/Be star with a close-in stellar companion and circumbinary disk. Our observations consist of images acquired via Keck II/NIRC2 with nonredundant masking and the pyramid wavefront sensor at

K
′

band (2.12 μm) and

L
′

band (3.78 μm). Sensitivity to low-mass accreting companions and cool disk material is high at

L
′

band, while complimentary observations at

K
′

band probe hotter material with higher angular resolution. These multiwavelength, multiepoch data allow us to differentiate the secondary stellar emission from disk emission and deeply probe the structure of the circumbinary disk at small angular separations. We constrain architectural properties of the system by fitting geometric disk and companion models to the

K
′

- and

L
′

-band data. From these models, we constrain the astrometric and photometric properties of the stellar binary and update the orbit, placing the tightest estimates to date on the V892 Tau orbital parameters. We also constrain the geometric structure of the circumbinary disk, and resolve a circumprimary disk for the first time.
Planetary Engulfment Prognosis within the ρ CrB System
Authors: Kane Stephen R.
Published: November 2023

Exoplanets have been detected around stars at various stages of their lives, ranging from young stars emerging from formation to the latter stages of evolution, including white dwarfs and neutron stars. Post-main-sequence stellar evolution can result in dramatic, and occasionally traumatic, alterations to the planetary system architecture, such as tidal disruption of planets and engulfment by the host star. The ρ CrB system is a particularly interesting case of advanced main-sequence evolution, due to the relative late age and brightness of the host star, its similarity to solar properties, and the harboring of four known planets. Here, we use stellar evolution models to estimate the expected trajectory of the stellar properties of ρ CrB, especially over the coming 1.0–1.5 billion yr as it evolves off the main sequence. We show that the inner three planets (e, b, and c) are engulfed during the red giant phase and asymptotic giant branch, likely destroying those planets via either evaporation or tidal disruption at the fluid-body Roche limit. The outer planet, planet d, is briefly engulfed by the star several times toward the end of the asymptotic giant branch, but the stellar mass loss and subsequent changing planetary orbit may allow the survival of the planet into the white dwarf phase of the stellar evolution. We discuss the implications of this outcome for similar systems and describe the consequences for planets that may lie within the habitable zone of the system.
Radio Emission and Electric Gaps in Pulsar Magnetospheres
Authors: Bransgrove Ashley , Beloborodov Andrei M. , Levin Yuri
Published: November 2023

The origin of pulsar radio emission is one of the old puzzles in theoretical astrophysics. In this Letter, we present a global kinetic plasma simulation that shows from first principles how and where radio emission can be produced in pulsar magnetospheres. We observe the self-consistent formation of electric gaps that periodically ignite electron-positron discharge. The gaps form above the polar cap and in the bulk return current. Discharge of the gaps excites electromagnetic modes, which share several features with the radio emission of real pulsars. We also observe the excitation of plasma waves and charge bunches by beam instabilities in the outer magnetosphere. Our numerical experiment demonstrates that global kinetic models can provide deep insight into the emission physics of pulsars and may help interpret their multiwavelength observations.
Global Hall MHD Simulations of the Solar Wind Implantation Flux on the Lunar Surface
Authors: Xie Lianghai , Li Lei , Wang Huizi , Tang Binbin , Wang Jindong , Zhang Yiteng , Shi Quanqi , Zhou Bin , Feng Yongyong
Published: November 2023

The solar wind can directly interact with the lunar surface and provide an important source for surface space weathering and water generation. Here we study the solar wind implantation flux on the lunar surface with global Hall MHD simulations. The shielding effects of both the Earth’s magnetosphere and lunar magnetic anomalies are considered. It is found that a large-scale lunar mini-magnetosphere can be caused by the solar wind interaction with the magnetic anomalies on the lunar far side, which causes a large shielding area on the surface. In addition, the Earth’s magnetosphere brings a longitudinal variation in the implantation flux, with minimum fluxes at 0° longitude. With the integrated flux over a lunation, we find that there are some local cavities on the implantation flux map, which are colocated with both the magnetic anomalies and the lunar swirls. Further studies show that there is a south–north asymmetry in the implantation flux, which can be used to explain the lower water content observed in the southern hemisphere. Our results provide a global map of the solar wind implantation flux on the lunar surface and are useful for evaluating the large-scale effect of solar wind implantation and sputtering on the space weathering and the water or gas generation of the surface.
Dynamics of Bacterial white spot disease spreads in Litopenaeus Vannamei with time-varying delay
Authors: Liu Xue , Meng Xin You
Published: November 2023

In this paper, we mainly consider a eco-epidemiological predator-prey system where delay is time-varying to study the transmission dynamics of Bacterial white spot disease in Litopenaeus Vannamei, which will contribute to the sustainable development of shrimp. First, the permanence and the positiveness of solutions are given. Then, the conditions for the local asymptotic stability of the equilibriums are established. Next, the global asymptotic stability for the system around the positive equilibrium is gained by applying the functional differential equation theory and constructing a proper Lyapunov function. Last, some numerical examples verify the validity and feasibility of previous theoretical results.
Breaking Up and the Value of Commitment
Authors: Healey Richard
Published: November 2023

While love and personal relationships are the subjects of rich and sophisticated literatures, philosophical writing about the end of special relationships is much harder to come by. However, the end of special relationships is a significant part of our lives and gives rise to a number of philosophical questions. In this article, I explore the normative significance of the end of special relationships, with a particular focus on the case of breaking up in the context of committed romantic relationships. Specifically, I address three questions. First, what does A do when A breaks up with B? Second, what normative effect will A’s breaking up with B have on the relationship-based duties, reasons, and permissions that are partly constitutive of A and B’s relationship? Third, how is the ability to break up consistent with the commitment that many longer-term romantic relationships involve? In response to the first and second questions, I argue that breaking up is a neglected example of a normative power and develop a tripartite account of the normative effects of exercising this power. In response to the third question, I develop an account of the nature and value of commitment within romantic relationships and show how the power to exit a relationship by breaking up is consistent with this form of commitment.
Convergence and Shared Reflective Equilibrium
Authors: Baumgaertner Bert , Lassiter Charles
Published: November 2023

We build a model of the reflective equilibrium method to better understand under what conditions a community of agents would achieve a shared equilibrium. We find that, despite guaranteeing that agents individually reach equilibrium and numerous constraints on how agents deliberate, it is surprisingly difficult for a community to converge on a small number of equilibria. Consequently, the literature on reflective equilibrium has underestimated the challenge of coordinating intrapersonal convergence and interpersonal convergence.
No Platforming and Academic Freedom
Authors: Elford Gideon
Published: November 2023

Much of the popular debate that surrounds no platforming centres on its putatively corrosive impact on free speech. This is apt to give a misleading picture of the particular puzzle that no platforming presents. Focusing on the university specifically, I contend that no platforming is distinctively objectionable not because it necessarily runs counter to general free speech values but when and because it is inconsistent with principles of academic freedom. This is because it conflicts with the status of members of the academy as those with the legitimacy to determine the appropriate bounds of free inquiry within the university. No platforming is objectionable insofar as it undercuts the authority of academic faculty in determining which speech, and by whom, is consistent with its purpose as an academic institution. Existing debates over no platforming have been too focused on which views are (or are not) given a platform and insufficiently attentive to the question of who decides who or what to platform. On the view defended here, no platforming by students is objectionable because, under principles of academic freedom, they should not be included in the constituency with the right to constrain the platforming of others.

Published: November 2023

Over recent years, the rate of adoption of artificial intelligence (AI) in the healthcare sector has grown. However, little is known about the success and failure factors. Therefore, this chapter presents a narrative review around the concepts, critical factors, impacts, and challenges behind AI adoption in the healthcare sector. 50 papers were found in the Scopus and Web of Science databases during the period from 2018 to June 2023. The results revealed that the adoption of AI was affected by perceived benefit, perceived ease of use, social influence, attitudes, training, top management support, and more. It was also shown that the challenges of adopting AI are its high cost, unprepared infrastructure, low level of expertise, resistance to change, security concerns, and trust. Consequently, this research advances our theoretical understanding of AI adoption in healthcare organizations in different economic and cultural contexts; and it can provide insights to various stakeholders for effective AI adoption.

The Impact of Health Crisis on the Volatility of Commodity Price Return
Authors: Jmaii Amal , Gargouri Ramla
Published: November 2023

This chapter examines the impact of the Covid-19 pandemic on commodity price returns, taking into consideration the role of economic policy uncertainty. Using global monthly data from September 2019 to September 2022, and applying the ARDL model, the study shows that Covid-19 has opposite effects on oil and gold price returns. While oil price returns dropped dramatically, gold continued to rise, serving as a safe asset during this health crisis. Moreover, the results indicate that economic uncertainty has a significant impact on these two commodities, as their importance to the global economy extends beyond their roles as raw materials. Therefore, an uncertain event can affect their stability. These findings can be beneficial to investors and decision-makers, as they should consider turning to gold in times of economic turbulence and uncertainty due to its resistance despite the Covid-19 pandemic.
Changing methods of teaching and learning, and assessment in the new normal in undergraduate medicine
Authors: Ponnamperuma Gominda G. , Samarasekera Dujeepa D.
Published: November 2023

The COVID-19 pandemic has radically changed the way we live and work, including the way we educate and train medical students. In the new normal, it is important for medical schools to adapt their methods of teaching and assessments to ensure that students are prepared for their future role as clinicians providing effective and empathetic care to their patients and communities. The paper discusses the ways in which the learning environment has changed for medical students as well as some of the challenges and ways forward in the new normal. The use of online platforms to conduct virtual lectures, seminars, and tutorials enabling students to learn from anywhere, at any time, and at their own pace is one of the major changes we saw; which also saw poor quality learning material being developed. We also saw some schools employing simulation-based learning to provide students with hands-on training in a safe and controlled environment. Both virtual platforms and simulation were used in student assessments in a few healthcare training institutions during the pandemic. The key to successful learning in the new normal is to anchor teaching-learning activities in a systematic way using best evidence medical education. A blended learning approach can provide students with the benefits of both online and in-person learning, while also accommodating the needs of students who cannot attend in-person classes in the new normal. Learning from the mistakes and if we consider some of the approaches adopted during the pandemic as pilots, educators can build a robust learning environment to ensure that medical students receive the best possible education and training, while also reducing the risk of exposure to future pandemics and ensure the continuity of learning.
The effect of sex ratio and group density on the mating success of two lines of Delia platura (Diptera: Anthomyiidae)
Authors: Bush-Beaupré Allen , Bélisle Marc , Fortier Anne-Marie , Fournier François , Savage Jade
Published: November 2023

The seedcorn maggot, Delia platura (Meigen) (Diptera: Anthomyiidae), is reported as a polyphagous pest species found in numerous crops, including onion, corn, crucifers, and soy. Two morphologically identical genetic lines of D. platura (H- and N-lines) with distinct distribution ranges were recently discovered. Although many biological traits have been described for D. platura, no study to date has been conducted on the life history strategies and reproductive behaviours of its two lines. Using laboratory-reared colonies, this project investigates the effect of group composition (sex ratio and density) on the mating success and preoviposition period of the two D. platura lines. We found a substantial increase in mating success with increasing proportion of males within mating groups for both lines, whereas we found group density had negligible effects. However, the H-line had a lower average mating probability across treatments compared to the N-line. The preoviposition period decreased as the ratio of males to female increased at low density only for the N-line, and the opposite trend was observed at high density for both lines. These results suggest differences between the mating systems of these two lines, thereby highlighting the need for further research into the factors that influence their respective mating systems.
Performance and Acoustics of a Stacked Rotor with Differential Collective Pitch
Authors: Johnson Chloe , Sirohi Jayant , Jacobellis George , Singh Rajneesh
Published: November 2023

Performance and acoustics of a 1.108-m radius stacked rotor in hover with an axial spacing between the upper and lower rotors of 0.73 chords were measured. The differential collective pitch of the rotor system, de ned as half the difference between the upper rotor pitch and lower rotor
pitch was varied along with the azimuthal spacing between the upper and lower blade sets. Coupled comprehensive analysis and acoustics simulations were conducted using the Rotorcraft Comprehensive Analysis System, the acoustic solver PSU-WOPWOP, and the Brooks, Pope, and Marcolini method implemented
in ANOPP2. Increased sensitivity to azimuthal spacing was measured for large, negative differential collectives, resulting in a 76.5% change in total rotor thrust and a 46% change in total rotor power over 11.25 ° change in azimuthal spacing. The trends in individual and total system thrust
were predicted with good accuracy, but the total power was overpredicted. Overall sound pressure level decreased by 3.5 dB at – 2° differential collective and 90° azimuthal spacing due to reduced broadband levels, indicating a possible quiet mode of operation for this type of
rotor. By assessing the highest performance and lowest noise, an optimum rotor con guration was observed at an azimuthal spacing of – 45° and differential collective of 2°. Acoustic predictions captured tonal and broadband noise trends in most conditions. Conditions where broadband
noise was underpredicted could be a result of vortex interactions not modeled by the broadband simulations.

Athletic Training Students’ Mental Health Recognition and Referral Skills, Part 2: Perceptions of Pedagogical Strategies
Authors: Anderson Alyssa S. , Pitney William A. , Armstrong Kirk J. , Kinslow Beth
Published: November 2023

Context

The increased prevalence of mental health conditions and the use of telehealth for patient care have exposed gaps in athletic training professional and continuing education. Here, we explore athletic training students’ perceptions of virtual pedagogical strategies for the delivery and application of concepts related to mental health recognition and referral, which may help educators determine best practices.

Objective

To examine students’ experiences and perceptions of Mental Health First Aid (MHFA) training, case-based learning, and standardized patient encounters.

Design

Qualitative portion of a sequential, explanatory mixed-methods design.

Setting

Individual interviews via video conference.

Patients or Other Participants

A convenience sample of graduate athletic training students from Commission on Accreditation of Athletic Training Education-accredited professional athletic training programs who participated in the MHFA training and secondary encounters were recruited. Twenty-two participants (11 from each intervention group; 45.5% male, 54.5% female; age = 24.59 ± 2.3) were interviewed.

Data Collection and Analysis

Interviews were recorded using Zoom and then transcribed. The Qualitative Analysis Guide of Leuven method was used to analyze the data to determine emergent themes. Strategies to enhance trustworthiness included an audit trail, member checks, and peer debriefing.

Results

Five higher order themes emerged from the interview data, as follows: (1) perceived value of MHFA training, (2) engaged learning and facilitated feedback, (3) capability, (4) comfort and confidence, and (5) authenticity. These themes were organized into the following 3 overarching dimensions: knowledge, skills, and pedagogy. Participants described how the opportunity to apply their knowledge and practice their skills with an athletic training-specific scenario helped them feel more equipped for future patient care.

Conclusions

Regardless of simulation strategy, the opportunity to practice influenced participants’ knowledge and feelings of confidence and capability. The MHFA training and simulated encounters were engaging techniques that incorporated feedback and provided elements of authentic patient interaction.

The production of alternative clean energy vehicles provides a sustainable
solution for the transportation industry. An effective battery cooling system is
required for the safe operation of electric vehicles throughout their lifetime.
However, in the pursuit of this technological change, issues of battery
overheating leading to thermal runaways (TRs) are seen as major concerns. For
example, lithium (Li)-ion batteries of electric vehicles can lose thermal
stability owing to electrochemical damage due to overheating of the core. In
this study, we look at how a different melting point phase change material (PCM)
can be used to delay the TR trigger point of a high-energy density lithium-iron
phosphate (LiFePO4) chemistry 86 Amp-hour (Ah) battery. The battery
is investigated under thermal abuse conditions by wrapping heater foil and
operating it at 500-W constant heat conditions until the battery runs in an
abuse scenario. A comparative time delay methodology is developed to understand
the TR trigger points under a timescale factor for different ambient conditions
such as 25°C, 35°C, and 45°C. In the present study, two different types of PCMs
are selected, that is, paraffin wax which melts at 45°C and Organic Axiotherm
(ATP-78) which melts at 78°C. Modeling results suggest that the TR trigger point
and peak onset temperature are greatly influenced by the battery operating
temperature. The concluded results indicate that by submerging the battery in
PCM, the TR trigger point can be greatly delayed, providing additional time for
the driver and passenger to evacuate the vehicle. However, the present findings
also reflect that fire propagation cannot be completely extinguished due to the
volatile hydrocarbon content in the PCM. Hence from this study, it is
recommended that whenever using a PCM-equipped passive cooling strategy, thermal
insulation should be provided at the wall of the PCM to delay the TR propagation
from one battery to another at pack-level configuration.
Questions of Peace: Judges 6:11-32 and the Obstacles to Harmony between Gideon and His Elders
Authors: Martin Lee Roy
Published: November 2023

The Hebrew Bible exhibits a deep interest in the transmission of the faith tradition from one generation to the next, and the book of Judges is no exception. As Judges begins, the passing of a generation is signaled by the death of Joshua (Judges 1:1), which is soon followed by the story of Caleb, his daughter, and his nephew (1:12-15). Then, Israel’s failure to pass on the faith to the next generation is noted in Judges 2:10. Throughout the book, the narratives of the judges report the ups and downs of each succeeding generation as one judge after another rises up, brings deliverance, and eventually dies (3:7-16:31). Near the center of the book, we find the story of Gideon (6:12-8.32), whose goal is the defeat of the Midianites and the restoration of peace to his community (6:24). Gideon’s first conflict, however, is with his own father and with the other elders in his village. In response to Yahweh’s dramatic visitation, Gideon names his new altar “Yahweh is Peace,” but he soon learns that peace is complicated and elusive. This brief study of Gideon’s pursuit of peace will be structured around four piercing questions found in the narrative: “Where are all his wonders?” (6:13), “How can I save Israel?” (6:15), “Who has done this thing?” (6:29), and “Would you plead for Baal?” (6:31). Each of these questions probes Gideon’s engagement with his elders and causes the reader to question the possibility of peace.
Understanding Agape Leadership: A Scoping Review
Authors: Peekunnel Sojan Paul , Srinivas Vijayalaya
Published: November 2023

Agape, a Greek term for unconditional love, is often overlooked in the context of leadership, which has traditionally emphasized control and dominance. Agape leadership is a type of leadership that places the well-being and growth of individuals, communities, and society at the forefront. This style of leadership is characterized by a profound sense of compassion and consideration for others and is grounded in the principles of love, compassion, and empathy. This paper reviews the literature on agape leadership, exploring how it is conceptualized, practiced, and studied. The review finds that agape leadership is linked to favourable results, including increased trust, motivation, performance, respect, and collaboration, in which people can thrive and reach their full potential. This style of leadership is not only focused on achieving specific goals or outcomes, but also on fostering a sense of purpose, meaning, and fulfilment in the lives of those being led. The leadership style of agape can bring about enduring and constructive transformations in society as it motivates and galvanizes individuals to collaborate toward a collective aspiration of a more promising tomorrow. Agape leaders also place a high value on personal growth and development and are constantly seeking to learn and grow in their own leadership journey.

The Bible contains important teachings about the mysterious relationship between Christ and the Church, as explained in Ephesians 5:22-33. This article highlights the deep relationship between Christ and the Church and has important implications for Christian families in the Church, where teaching about the Christian family especially from Ephesians 5:22–33 is only given or preached at the time of the marriage blessing, and even that is not explained well. So it can be said that the description of Ephesians 5: 22-33 is just a routine without meaning. In Ephesians 5:22-33 the apostle Paul uses the analogy of marriage to explain the relationship between Christ and His church. He compared the relationship between a husband and wife to the relationship that exists
between Christ and the church. Just as a husband is the head of his wife, Christ is the head of the church. It emphasizes the surrender of the church to the authority of Christ and the love and sacrifice Christ gave to His church. This passage emphasizes even more the sacrificial love that husbands must have for their wives, just as Christ loved the Church and gave himself for her, husbands are also called to love their wives as Christ loves and cares for the Church. This underscores the importance of selflessness, grace and devotion in a Christian marriage by each of the spouses. Ephesians 5:22-33 moderates the patriarchal view of marriage, and it re-expresses the concepts of submission and leadership in a family. The wife should always submit to her husband's authority as she would to Jesus Christ. The husband needs to always exercise his authority with love and try to imitate Christ.

Dermal Papilla Cells (DPCs) are mesenchymal cells residing at the base of the hair follicles. They play an important role in the hair cycle remodeling and hair follicle regeneration. In this study, DPCs were isolated, and cultured from human hair follicles and evaluated the expression of -SMA, versican by immunocytochemistry, and alkaline phosphatase activity. The human fibroblasts were used as a control to confirm the non-fibroblast DPCs. The results showed that the cells grew from the hair bulb and had fibroblast morphology. These bulb cells strongly expressed alkaline phosphatase activity -SMA, and versican while the human fibroblast lacked ALP activity and less expression of -SMA and versican. In conclusion, the protocol is established to isolate and culture DPCs from hair follicle bulbs, and ALP activity is suggested as the major marker for distinguishing DPCs and human fibroblasts.

Objectives: This study aimed to analyze the validity and reliability of the Turkish version of the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ) in patients with fibromyalgia (FM) syndrome by translating and culturally adapting the CPFQ to Turkish.

Patients and methods: One hundred seventeen patients (8 males, 109 females; mean age: 47.4±12.4 years; range, 18 to 77 years) diagnosed with FM according to the 2016 American College of Rheumatology FM diagnostic criteria between May 2021 and August 2021 were included in the reliability and validity study. The CPFQ was translated into Turkish, the intelligibility of the obtained Turkish version was evaluated by five patients and five healthcare professionals, and the final form of the questionnaire was prepared. Mini-mental state examination (MMSE), Fibromyalgia Impact Questionnaire (FIQ), and Hospital Anxiety and Depression Scale (HADS), which were proven to be reliable and valid in Turkish, were administered to the patients. For test-retest reliability, the Turkish version of the CPFQ was filled in two times with an interval of one week. Internal consistency was evaluated by calculating Cronbach's alpha. Validity was evaluated by looking at the correlations between the total score obtained from the Turkish version of CPFQ and the MMSE score, HADS depression and anxiety scores, and FIQ score.

Results: In the evaluation of internal consistency, Cronbach's alpha was found to be high in all subgroups. In test-retest reliability, intraclass correlation coefficient was high in CPFQ subgroups. The CPFQ showed a significant positive correlation with HADS depression and a moderately positive correlation with HADS anxiety and FIQ. A significant but weak negative correlation was detected between CPFQ and MMSE. While there was no significant correlation between MMSE and FM disease activity and HADS anxiety, there was a significant but weak negative correlation between HADS depression.

Conclusion: In this study, the Turkish version of CPFQ was shown to have high reliability and validity in FM patients. It was concluded that CPFQ could be applied to Turkish patients with FM.
