Published: September 2022

Esta investigación realizó un análisis socioambiental de la ciénaga Grande de Malambo para identificar los factores que contribuyen al deterioro, la falta de conciencia ambiental de los pobladores de la vereda el Espinal. Los cuerpos de agua y ciénagas en todo el mundo se encuentran en peligro debido a los grandes problemas de contaminación a los cuales han sido sometidos durante los últimos años. Esta ciénaga ha sido fuertemente degradada al incrementar la quema y tala de árboles en la rivera, pero principalmente por la contaminación por vertimiento de residuos sólidos y líquidos, provenientes del sector industrial, que ha causado la desaparición de hábitat de peces y la consecuente pérdida de la actividad pesquera que realizaron tradicionalmente los pobladores. La metodología de acción participación busca que la población obtenga los conocimientos como resultados de sus propias indagaciones y actuaciones, permitiendo obtener resultados y conocimientos que transforman desde la pedagogía ambiental, las prácticas de los habitantes y su cultura ambiental misma. La progresiva participación comunitaria en actividades de limpieza y dragado de los arroyos que llevan las aguas a la ciénaga, llevaron a estrategias de educación ambiental y sentido de pertenencia por el cuidado de la ciénaga. fortalecen el cuidado y preservación del medio ambiente y el mejoramiento de las condiciones y calidad de vida de esta población.

Published: September 2022

El desarrollo de oclusión intestinal después de la cirugía abdominal superior e inferior es parte de la vida cotidiana de cada cirujano, las adherencias postoperatorias son causa de una considerable morbilidad y su prevención se puede considerar un problema de salud pública. En Ecuador, no hay ninguna recomendación validada (que, en relación al trato gentil a los tejidos, por lo obvio no se menciona) sobre la prevención de las adherencias. Se realizó un estudio descriptivo, retrospectivo y transversal, mediante una revisión bibliografica de artículos de revistas, tesis doctorales, páginas web, entre otros. Como resultados se obtuvo, que la obstrucción intestinal secundaria a adherencias ocupa el segundo lugar con el 17%. El 62.3% fueron varones y el 37.7% mujeres. Con mayor frecuencia entre los 15 a 30 años. El tipo de cirugía previa más frecuente fue la apendicetomía con 44.9%, la mayoría de pacientes presentan una cirugía previa con 72.5%, el tiempo transcurrido desde la última laparotomía fue menos de un año con 34.2%. Al 62.3% se realizó adherenciolisis y al resto resección y anastomosis intestinal. La infección de herida operatorio como la complicación más frecuente con el 8.7% y la tasa de mortalidad fue 2.9%. de esta manera de concluye en que las principales características epidemiológicas de los pacientes con obstrucción intestinal: afecta a los varones y grupo etario entre 15-30 años. La apendicetomía por peritonitis generalizada, una cirugía previa y un tiempo menor de un año al trauma inicial, fueron los principales antecedentes quirúrgicos.

Effective team building as an activator of cluster community progress
Authors: Karpenko Andrii , Doronina Olha , Karpenko Natalia
Published: September 2022

In recent years, the cluster motion has become more active in Ukraine. The setting of research tasks, their relevance and pragmatism are due, first of all, to the perception of the cluster community as an environment for making optimal decisions in uncertainty conditions and producing innovations necessary for the vital activity of society and the economy. Secondly, the vision of cluster formations as specific organizational forms, the development of which is possible only if a coordinated and highly motivated team with common values is formed. The activity of the Ukrainian Cluster Alliance, which is currently the largest and most authoritative cluster community, was studied. It is substantiated that the formed management structure of the cluster community, the defined its mission and goals, the distribution of powers and the adopted ethical rules are able to ensure a trust between participants. At the same time, the formation of a project management system in cluster activities should be supported by appropriate team building measures.

The reasons for the decrease of team building effectiveness and the factors that should be the basis of this process are summarized. The main stages of team building in project teams are structured, which will allow successful implementation of project management within the cluster community. The further direction of scientific and practical work is defined as the development of personnel and management potential of cluster formations, in particular through the development of a model for training cluster leaders which will be able to be an effective team leaders.
Main trends and development forecast of bread and bakery products market
Authors: Mickiewicz Bartosz , Britchenko Igor
Published: September 2022

Bakery products are very important in human nutrition and are the basis of any daily diet. Their social significance is determined by the traditions and habits of the population of the countries, accessibility for all groups of the population, diverse assortment, including bakery products for functional and specialized purposes. The up-to-date trend is to expand the assortment of functional bakery products, the use of which will provide the body’s need for the necessary macro- and micronutrients for an active and healthy lifestyle. In the bread and bakery products market, consumer preferences are constantly changing. Consumers prefer products that contain less fat and sugar. The market is in demand for bakery products that are healthy, while taste remains an important success factor. Manufacturers include popular healthy additives (grains, seeds and legumes) in their products. Particularly popular at present are ingredients from Eastern Europe and Asia: yuzu, sesame, matcha, shiso. Tropical fruits (passion fruit, mango, bergamot) and fragrances (dried hibiscus, lavender and rose) are predicted to become popular. This causes the complexity of demand segmentation, features of merchandising and pricing policy, features of consumer behavior and consumption psychology, etc. An assessment is given of the dynamics of production and consumption of bread and exports of products, and a forecast is made for the development of the world market for bread and bakery products. The results of the analysis are necessary to assess the level of food safety and to develop a strategy that takes into account the current trends in the global bread and bakery products market. Prospective trends for sustainable production of frozen bakery products have been developed.
EPIC 219511354, A Binary Pair of Active K-stars: Modeling Activity-induced Radius Inflation by Magneto-convection
Authors: Mullan D. J. , MacDonald J.
Published: September 2022

Magnetically active low-mass stars are observed to have their empirical radii R “inflated” and their empirical T
eff reduced relative to standard predictions. Models which have been proposed to replicate these discrepancies include magneto-convection (M-C), and/or star-spots (S-S). Here we raise the question: is there any reason to prefer a dominant role for either M-C or S-S in order to replicate the data? In the binary EPIC 219511354, the empirical M and R values have remarkably high (1%–2%) precision. To replicate these data, the S-S model requires almost the entire (88%–94%) secondary surface to be spotted. Here, we report that our M-C model fits the empirical R and T
eff values for both members of the binary within 1σ error bars without needing spots. If an areal spot coverage of 94% is regarded as physically implausible, the M-C model could be considered preferable over S-S in EPIC 219511354.
Color Ultrasound Image Watermarking Scheme Using FRT and Hessenberg Decomposition for Telemedicine Applications
Authors: Kumar Lalan , Singh Kamred Udham
Published: September 2022

Watermarking is a valuable technique for verifying medical images obtained through the internet for diagnosis. There is a greater need for security in medical pictures with ever- increasing security risks. This research presented a Finite Ridgelet Transform (FRT)-Hessenberg based watermarking scheme in medical images. The suggested paradigm is divided into two stages. Before watermark insertion, FRT is applied to medical images. The coefficients are combined into blocks of 4 x 4 and each block is decomposed using Hessenberg decomposition. The second column of the Q matrix is used to insert the watermark using the additive quantization technique. The results obtained from our experiment have given good visual quality of the watermarked images. The high PSNR value 53.6121 and NC value 1.0 show that our scheme is performing better. Moreover, the performance of our scheme is robust against several attacks. The consequences of this result imply that the anticipated scheme is effective for medical image watermarking.
Sodium-Glucose Cotransporter-2 Inhibitors: Risks vs. Rewards When Caring for Older Adults
Authors: Wilson Erica , Jones Aminah , Brandt Nicole J.
Published: September 2022

Managing multiple comorbidities is common in older adults. Thus, when a medication class, such as sodium-glucose cotransporter-2 (SGLT2) inhibitors, can potentially treat multiple conditions and prevent progression of chronic kidney disease, multiple guidelines must be followed when using these agents. The current article discusses risks and benefits of SGLT2 inhibitors, especially in the context of new evidence, and presents a case example. [

Occupational Therapy Practitioner Perspectives of the Role of Caregivers in Video Telehealth
Authors: Gately Megan E. , Waller Dylan , Metcalf Emily E. , Moo Lauren R.
Published: September 2022

The current article examines the role of caregivers to support patient participation in video telehealth, using data from interviews with occupational therapy practitioners at Veterans Health Administration. We found that caregiver participation allowed patients who might otherwise not be able to access video telehealth to do so, with patient factors, such as low technical literacy, contributing to caregiver involvement. In addition, caregiver participation varied by type of task performed. There were also benefits and barriers to caregiver participation. This study enhances our understanding of caregivers' role enabling patients to access video telehealth, which has implications for nursing professionals. [

Expansion of a House Calls Program for Patients With Dementia During COVID-19
Authors: DiTommaso Molly J. , Mohammad Natalie F.
Published: September 2022

Homebound older adults with dementia have increased health care use, hospitalization rates, and mortality risk, which are associated with considerable health care costs. A large, unmet need for individuals with dementia is home-based medical care. Although our institution has had a primary care program for homebound patients since 2019, we did not have an analogous program for patients with dementia before the coronavirus disease 2019 (COVID-19) pandemic. However, with increased health risks and challenges associated with the pandemic, we rapidly expanded the program to include facility-based older adults with dementia. We incorporated telemedicine and home-based visits to effectively provide patient-centered care that was aligned with their goals and preferences, and we describe a program example of how we provided care during a COVID-19 outbreak in a large facility. Further research is needed to capture potential cost savings and hospitalization rates for persons with dementia who receive home-based medical care. [

Authors: Iqbal Sajid , Samraiz Muhammad , Rahman Gauhar , Nisar Kottakkaran Sooppy , Abdeljawad Thabet
Published: September 2022

In this paper, we prove several new integral inequalities for the $ k $-Hilfer fractional derivative operator, which is a fractional calculus operator. As a result, we have a whole new set of fractional integral inequalities. For the generalized fractional derivative, we also use Young's inequality to find new forms of inequalities. Such conclusions for this novel and generalized fractional derivative are extremely useful and valuable in the domains of differential equations and fractional differential calculus, both of which have a strong connections to real-world situations. These findings may stimulate additional research in a variety of fields of pure and applied sciences.
Energy analysis of the ADI-FDTD method with fourth-order accuracy in time for Maxwell's equations
Authors: Zhang Li , Ran Maohua , Zhang Hanyue
Published: September 2022

In this work, the ADI-FDTD method with fourth-order accuracy in time for the 2-D Maxwell's equations without sources and charges is proposed. We mainly focus on energy analysis of the proposed ADI-FDTD method. By using the energy method, we derive the numerical energy identity of the ADI-FDTD method and show that the ADI-FDTD method is approximately energy-preserving. In comparison with the energy in theory, the numerical one has two perturbation terms and can be used in computation in order to keep it approximately energy-preserving. Numerical experiments are given to show the performance of the proposed ADI-FDTD method which confirm the theoretical results.
Autoethnography of Cultural Heritage Tourism Documentary Production
Authors: Swanson Jason R. , Johannigman Taylor
Published: September 2022

Using an auto-ethnographic approach, this chapter describes aspects of how a story about cultural and heritage tourism is produced as a documentary for public television. A documentary storytelling production about a proposed national heritage area in the United States provides a case study for the chapter. Included is a discussion of ethical dilemmas that arose during documentary production and how the dilemmas were addressed. Ethical dilemmas included dealing with concerns about protecting people and property, telling stories about subjects that could be viewed as controversial, covering narratives that have been neglected through history, and avoiding advancing stereotypes about people in the subject region. Solutions to dilemmas were found in how stories were crafted for the documentary production.

Authors: Solomon Emmanuel Nii-Ayi , Adu-Debrah Lorna Kankor , Braimah Stephen Mahama
Published: September 2022

Tourism destinations must be encouraged to tell their stories and share them with visitors. The objective of this study is to, firstly, increase the understanding of the role of storytelling in tourism destination promotion and, secondly, to ascertain the impact of storytelling on tourism destination promotion. In this chapter, tourism destinations are approached through the intriguing stories that are told about them. Stories have the potential to enhance and promote the qualities of a destination; hence, the chapter discusses the potential of storytelling as a strategic tool in “wrapping” or promoting destinations. It also provides the platform for discussion between various stakeholders at the destination in finding creative ways of promoting the destination. This chapter also discusses place storytelling and emphasises its relevance in promoting tourism destinations, and how stakeholders such as tour guides are employed as storytellers to promote key attributes of the destination.
Destination Storytelling as a Destination Branding Tool
Authors: Ülkü Abdullah , Erol Günay
Published: September 2022

This study discusses how storytelling can be used as a destination branding tool by examining some of the most visited sites in Turkey as an example of destination storytelling. Stories have been used to transfer knowledge and culture from generation to generation. Stories have become an innovative communication channel for destinations. Tourists no longer want to just buy an experience; they also want to have the stories behind the destination experience. From this point of view, storytelling has become indispensable for destinations. Destinations have symbolic meanings for tourists, and thanks to branding, destinations communicate to tourists some messages about themselves and are accordingly positioned in their minds. In this study, the formation process of destination storytelling, the effects of stories on the formation of the destination brand, and the destination brand are explained.
Does the Implementation of Green Human Resource Management Practices Help Boost Working Mother Performance?
Authors: Hj Abd Rahman Nur Aqilah Adilah , Susanto Heru
Published: September 2022

Green human resource management practices have been “the talk” when people start to focus on going green. Organizations prefer to use practices that can actually generate eco-innovations that could result in reducing of costs and wastes. The purpose of this chapter is to further investigate whether the implementation of green human resource management would actually help boost working mother performance. Twenty working mothers participated in the survey. The number of participants may be small, but knowing that these practices were not yet implemented in Brunei Darussalam, data are acceptable for testing. To conclude, only a few participants were aware of green human resource management and agree that implementing it would give positive impact towards their performance.
The Voluntary Disclosure Determinants in French Family Firms
Authors: Bechir Chenguel , Mansour Nadia , Brahmi Mohsen
Published: September 2022

The chapter studies the degree of voluntary disclosure of the French family companies and assesses the impact of several corporate governance determinants on this disclosure. The sample consists of annual reports from 142 listed French family companies for the year 2020. The empirical results show that the size of the company, the independence of the board of directors, and the size of the audit firm have a positive and significant influence on the level of voluntary disclosure, while the age of the company, contrary to the pre-determinant hypothesis, has a negative influence on the level of voluntary disclosure. On the other hand, the relationship was not significant between the dependent variable voluntary disclosure and the independent variables, which are leverage degree and concentration of ownership. The original value of this chapter is to identify the impact of certain characteristics on the level of disclosure in the annual reports of listed French firms.
Qualitative to Quantitative Non-Destructive Evaluation: A Concept for D-Sight Inspections of Aircraft Structures
Authors: Katunin Andrzej , Dragan Krzysztof
Published: September 2022

Non-destructive evaluation of structures is a key procedure in operation of aircraft structures, necessary to maintain their quality and integrity. Numerous non-destructive testing (NDT) techniques have been adapted to inspect aircraft structures and are currently used according to appropriate protocols. However, many of them provide only qualitative results, such as the D-Sight optical NDT technique used for inspections in aviation. In this study, a concept of improvement of the D-Sight technique is proposed by means of appropriate experimental program and processing procedures applied to the resulting images from inspection. It was demonstrated that appropriately selected processing methods may allow assessing damage quantitatively and improve the overall sensitivity and applicability of a given NDT technique.
Thermo-Mechanical Bending for Hybrid Material Plates Perfect-Imperfect Rectangular Using High Order Theory
Authors: Otmane Zerrouki , Slimane Merdaci , Adda Hadj Mostefa
Published: September 2022

In this paper, a higher order shear deformation theory is used to analyse the thermo-mechanical bending response of perfect-imperfect rectangular plates for hybrid ceramic and metal type (FGP) functionally graded plates with porosities. Based on the mixing law, the FG porous material qualities fluctuate with the thickness of the FGP layer. The equilibrium equations are found using the total potential energy approach. For simply supported (FGP) porous plates, the thermo-mechanical response is calculated. Analytical research shows the correctness of the existing high-order shear deformation theory in predicting the thermo-mechanical response of perfect-imperfect rectangular FG plates. Geometric characteristics, thickness ratios, gradient indices, porosity coefficients, mechanical loading, and thermal loading are all covered. According to the findings, the proposed hypothesis is more likely to be correct when it comes to the thermo-mechanical response of FG porous plates.
The role of supplier switching costs and supply chain responsiveness
Authors: Gunarathne G. C. I. , Weerasinghe K. V. , Thibbotuwawa A. , Perera H. N.
Published: September 2022

This study explored the effect of supplier switching costs on supply chain responsiveness in Sri Lankan Small and Medium-scale manufacturing firms (SMEs). It considered three types of switching costs: procedural switching costs, financial switching costs, and relational switching costs. Survey data were collected from 188 manufacturing firms and analysed using Structural Equation Modelling (SEM). The results revealed that, procedural switching cost was positively related to supply chain responsiveness, while the relational switching cost, the most important predictor, was negatively related. The relationship between financial switching costs and supply chain responsiveness was not significant. No significant direct relationship was found between supplier switching costs and supply chain responsiveness either, possibly due to a different set of intervening variables influencing this relationship. No significant impact was found on the price and product competition in the context of Sri Lankan manufacturing sector indicating that supplier switching costs do not play a significant role on these variables. Yet, there may be an influence from intervening variables due to internal organisational situation and external factors such as market conditions. Switching suppliers is not a big problem for some companies because they already have well-defined supplier networks with multiple providers for the same raw materials [1]. However, this differs based on companies’ relationships with suppliers (long-term or short-term contracts) and the availability of resource supplies [2].
Terminal pricing decisions of the port authority and the global terminal operator of the competing ports in Sri Lanka
Authors: Kavirathna C. A. , Hanaoka S. , Kawasaki T.
Published: September 2022

This study analysed competition at port and terminal levels resulting from the involvement of a port authority, Sri Lanka Port Authority (SLPA), and a Global Terminal Operator, China Merchant Port Holdings (CMPH), in the Colombo and Hambantota ports. It also considered the operators’ disparate interests in the two ports. The terminals’ pricing decisions of SLPA and CMPH were analysed taking into account the cooperation among the terminals in one port and the terminals owned by the same Global Terminal Operator and the competition from their different ownership types. Results revealed significantly different pricing decisions attributable to seven possible objectives of the SLPA along with profit and demand maximisation objectives of CMPH. Findings suggest that, if the SLPA reduces the terminal price charged by the Colombo International Container Terminal operated by the CMPH, the latter would behave as a “free rider”. Moreover, both the SLPA and CMPH would try to balance their interests in both ports, especially with their profit maximisation objective, which would result in less profits for both Colombo and Hambantota ports. The demand maximisation objective of CMPH would reduce charges at its terminals as opposed to its profit maximisation objective. Colombo Port would receive higher demand if the SLPA focuses on user surplus maximisation.

Authors: Ragasa Mulugeta Bonsa , Legesse Tesfaye Girma , Wudineh Birhanu Asrat , Abayneh Helina
Published: September 2022

It is estimated that 1.35 million people die each year as a result of road traffic injuries worldwide, with Africa having the highest annual rate. Ethiopia has the highest fatality rate in road traffic accidents, at 79%. There is no well-established emergency medical system in Ethiopia to provide pre-hospital trauma care. A crosssectional study was conducted at selected public hospitals in Addis Ababa. Purposive sampling was used to select the victims who arrived at the emergency department by ambulance. Data was gathered through structured questionnaires administered by an interviewer and a review of victims’ medical records. SPSS Version 25 was used to analyze the data. In this study, 262 victims took part, with a 94% response rate. Patient positioning (50.8%) was the most commonly provided service, followed by bleeding control (43.5%). Within the first 24 hours, 8.4% of the victims died. The first 24-hours of injury-related death were significantly associated with head/neck/spine injury and total pre-hospital time. Action should be taken to increase the availability of necessary equipment in ambulances and the number of paramedic personnel.
Emergency medicine residents: Don’t give up!

Published: September 2022

In this issue of Emergency Care Journal we publish a letter from some young colleagues from CoSMEU (the Italian association of Emergency Medicine, EM).1

They express great concern on the several aspects the EM situation in Italy.2 The first issue is the collapse of the Emergency Departments (ED)2,3 caused by crowding/boarding combined with low available resources, particularly regarding EM physicians. The logical consequence is that EM is no longer attractive neither for “older” (indeed, not so much) physicians who are leaving their careers in great number, or “younger” doctors who are not attracted by the EM specialization,4 despite growing available access (up to 1000 training positions) in the recent years.

Authors: Chen Kuo-Wei , Lin Yen-Heng , Hsu Chiu-Hao , Lu Chi-Ju , Tang Sung-Chun , Lee Chung-Wei , Chiang Pin-Yi
Published: September 2022

Background:

Endovascular thrombectomy (EVT) for acute ischemic stroke associated with tandem lesion is challenging. Achieving rapid intracranial revascularization and managing the extracranial lesion without complications are the main challenges.

Materials and Methods:

The balloon angioplasty followed by aspiration of large-vessel occlusion (BAFALO) technique was used to address this clinical issue. A review of a prospectively maintained stroke registry from January 2015 to April 2020 was performed. Patients had stroke with TO and treated with the BAFALO technique were included.

Results:

Twelve patients were enrolled: 11 had anterior circulation stroke, and 1 had posterior circulation stroke. There were 10 ipsilateral internal carotid artery stenosis/occlusion, one left common carotid artery to subclavian artery bypass stenosis, and 1 vertebral artery orifice stenosis. The median National Institutes of Health Stroke Scale score was 16 (interquartile range [IQR]: 14–16). Revascularization with a Modified Thrombolysis in Cerebral Infarction score of 2b or more was achieved in 11 (92%) patients. The median puncture-to-revascularization time was 25 min (IQR: 19.5–31). Emergent stent implantation was performed in five (42%) patients. Three had distal protection devices (DPDs) with no distal embolization. Two patients did not use a DPD, and one had intracranial reocclusion. Eight (67%) proximal stenotic vessels remained patent. No symptomatic intracranial hemorrhage occurred. Eight (67%) patients had favorable clinical outcomes (modified Rankin Score 0–2 at 90 days).

Conclusion:

While managing TO, the BAFALO technique could achieve rapid intracranial revascularization and treat extracranial lesions under embolic protection. These merits translate into favorable clinical outcomes.

Cerebral toxoplasmosis and tuberculosis miliaria are major and serious opportunistic infections, usually occurring in HIV-positive individuals with CD4 counts< 200 cells/mm3. We report here a case in a 56-year-old patient with toxoplasmosistuberculosis- HIV co-infection with CD4 count of 446 cells/mm3. Under multidrug therapy (cotrimoxazole and first-line antituberculosis drugs), the favorable evolution (clinical improvement) was observed on the fourteenth day of cotrimoxazole treatment. High antiretroviral therapy (HAART) was reintroduced on the fifteenth day of anti-tuberculosis treatment, after two sessions of psychotherapy. Through this clinical case, the practitioner should be warned about the possibility of concomitant opportunistic infections in an HIV immunocompromised patient, especially without chemoprophylaxis, whatever his CD4 count.

Context and objective. Viral hepatitis B (VHB) by its evolution can lead to recovery or to a chronic form. This chronic form, a source of new contaminations, is not documented among voluntary blood donors (VBD) in Bangui and Bimbo. The present study aimed to determine the prevalence of chronic VHB among VBD in the two cities in the Central African Republic (CAR). Methods. The study carried out at the Bangui National Blood Transfusion Center was retrospective and focused on serological control data from VBD from Bangui, capital of CAR and Bimbo. The exhaustive sampling is from July 2013 to December 2019. A VBD carries a chronic infection if the VHB surface antigen persists for more than six months. Results. Serological control data from 702 VBD aged 18 to 62 years were analyzed. Male sex predominated at inclusion (n = 598). The prevalence of chronic VHB was 70.5 %. This prevalence was higher among young VBD aged 25 to 34 years (30.4 %), the male gender (58.4 %) and VBD residing in Bangui (61.2 %). The chronic form was significantly associated with young age (18 to 44 years) and male sex (p< 5%). Co-infection with HIV and hepatitis C was found in 5.5 % of cases (39/702). Conclusion. The prevalence of chronic VHB is very high in VBD from Bangui and Bimbo. The chronic form was significantly associated with age and sex. Free viral load and antiviral treatment are prospects to be implemented.
Eosinophilic granulomatosis with Anti-MPO-C-ANCA-associated polyangitis: a case report illustrating the diagnosis difficulty

Eosinophilic granulomatosis with polyangitis (EGPA), formerly known as Churg-Strauss syndrome, with antineutrophil cytoplasmic autoantibodies (ANCA) is a rare vasculitis. The CANCA is mainly antibodies to proteinase-3 and the P-ANCA is antibodies to myeloperoxidase (MPO). The EGPA with C-ANCA with antibodies anti-MPO has never been described in Subsaharan Africa. Medical investigations allowed excluding infectious diseases, malignancies and other rheumatic affections. Thus, clinical and paraclinical data suggested an atypic EGPA with MPO-C-ANCA. In our knoweledge, we reported here the first case of EGPA wtih MPO C-ANCA from Madagascar. The EGPA was succesfully controled with steroid treatment.
A Comparative Theological Approach to Virtue Ethics: Making Space for an African Perspective
Authors: Aihiokhai SimonMary Asese
Published: September 2022

The twenty-first century world has radically been defined by multiple crises, including wars and grandiose exploitation of the poor by those with political and economic power. To address these crises, one must turn to virtuous life notions. In doing this, society has to learn from different religious and cultural wisdom. Consequently, a case is being made in this work that African ethical thoughts can enrich Christian notions of the virtuous life. African philosophical and cultural notions of community are relevant to understanding the virtuous life in Christian theology as a constitutive aspect of what it means to be human.
Cynicism, Denialism, and Fatalism: The Triple Pandemism of Covid-19 Conspiracy Theories
Authors: Okoli Al Chukwuma , Sule Peter
Published: September 2022

Humanity is under siege with Covid-19. Whilst the crisis aggravates, the world is also grappling with yet another challenge - a global misinformation conundrum. This arises from the spread of contagious conspiracy theories that obfuscate understanding the pandemic at best. Incidentally, the conspiracy theories have gone as viral as Covid-19 itself, spreading just as swiftly digitally as the virus does physically. The outcome has been a spectrum of attitudinal patterns, ranging from cynicism and skepticism to outright denialism and fatalism. Using a conversational analysis that is predicated on extant literature and personal insights, the paper examines the import of conspiracy theories as a major complication of the Covid- 19 challenge. The paper posits that the theories have produced narratives and attitudinal outcomes that not only misrepresent the pandemic but also complicate its mitigation.
Logical Realism and Ezumezu Logic
Authors: Abakedi Dominic Effiong , Iwuagwu Emmanuel Kelechi
Published: September 2022

This paper examines the metaphysical status of Ezumezu logic in the direction of logical realism. While presenting Ezumezu logic as a prototype of African logic, Chimakonam makes statements that somewhat entail logical monism. Using the method of critical analysis of related literature, the paper argues that presenting Ezumezu logic as one of the prototypes of African logic while at the same time making claims that elevate it to a hegemonic status, gives rise to what is regarded in the paper as the monist-pluralist paradox. Drawing lessons from Abakedi’s ID paradox, the paper argues that a monist logical foundation for African logic cannot be consistently defended without paradoxes. The paper proposes that different African philosophies should be grounded by different African logics such that one need not be trained in one particular prototype such as Ezumezu logic or argue in conformity to it to qualify as an African professional or scholar.
COVID-19 and Affirmative Action: A Response
Authors: Msimang Phila M.
Published: September 2022

Ovett Nwosimiri argues in a paper he published in 2021 that affirmative action and preferential hiring policies are no longer appropriate for South Africa because of the economic impact of the COVID-19 pandemic. The case he makes is that since COVID-19 has impacted people of all races, there should no longer be any consideration of race in hiring policies and practices. He claims that continued preferential hiring practices unfairly discriminate against non-designated groups. I argue that this claim presumes that the pandemic has been a devastating but equalizing force in economic opportunity and participation for people in South Africa. I show that this claim is simply false and that the falsity of his claim undermines Nwosimiri’s case. Nwosimiri does not take account of the false premise his case is founded on because of his inappropriate methodological choice to ignore empirical evidence that has bearing on his argument.
Relativization in Kaakye
Authors: Abunya Levina Nyameye , Osam E. Kweku
Published: September 2022

This paper describes the relative clause (RC) in Kaakye, a Kwa (Niger-Congo) language. Evidence is provided to show that Kaakye RC is strictly postnominal and that both the head noun and its referent within the RC are obligatorily expressed. Unlike RCs in some Kwa languages that are close neighbours, the head noun in a Kaakye RC obligatorily takes a determiner. The language also uses the pronoun retention strategy to indicate the canonical positions the head noun occupies in the RC. Where the pronoun retention strategy is used, a resumptive pronoun co-references the head noun in person, number, and animacy to explicitly state the referent of the head noun within the RC. Based on the available synchronic data, we argue that Kaakye object resumptives in RCs are number sensitive unlike other Kwa languages. The paper further demonstrates that all NP positions on the Accessibility Hierarchy are relativizable.
Combating cultural imperialism and cultural misorientation to preserve Afrikan intangible cultural heritage

Published: September 2022

This study aims to address combating cultural imperialism and cultural misorientation to preserve Afrikan=Black intangible cultural heritage noting that the priority must be on indigenous Afrikan=Black people to push our own agenda. The study takes the 2019 UNESCO-ICM Open School as a case study in terms of substantive efforts (or lack thereof) to combat cultural imperialism and cultural misorientation. The study addresses matters of terminology, the implications of using the equal sign between Afrikan and non-Afrikan concepts, cultural misorientation and disorientation, false narratives and alien-self/anti-self-disorders, soft power, what must be done in terms of combating these ills. The study concludes with a section addressing the way forward for the Afrikan=Black Warrior Tradition and Afrikan Combat Scientists in light of the preservation of our intangible cultural heritage.
