Authors: Atreides Kyrtin
Published: June 2022

Methods of improving the state and rate of progress within the domain of philosophy using collective intelligence systems are considered. By applying mASI systems superintelligence, debiasing, and humanity’s current sum of knowledge may be applied to this domain in novel ways. Such systems may also serve to strongly facilitate new forms and degrees of cooperation and understanding between different philosophies and cultures. The integration of these philosophies directly into their own machine intelligence seeds as cornerstones could further serve to reduce existential risk while improving both ethical quality and performance.

Dependence of the Turkish Tourism Sector on Five
Countries of Origin and Tourism Demand
Authors: Kaymaz Volkan
Published: June 2022

Because of its fragile structure, tourism is a sector where tourist arrivals fluctuate, and competition is high. Tourism demand is changing rapidly according to many different factors. Most of the tourist arrivals to Turkey are from European countries. This paper analyzes the relationship between tourist arrivals from countries of origin and basic macroeconomic variables in the period between 2010-2020. The study, which uses the Autoregressive distributed lag (ARDL) boundaries testing approach, shows that tourist arrivals interact with key macroeconomic variables such as exchange rate and unemployment rate. This situation reveals the necessity of eliminating dependence on certain countries in the tourism sector and turning to different markets.

The Behavior of HgMn Stars in the Far-UV -6: κ Cnc
Authors: Monier Richard
Published: June 2022

The analysis of eighteen high resolution SWP spectra of the HgMn star HD 78316 (κ Cnc) recorded by the International Ultraviolet Explorer reveals that the far-ultraviolet flux of this star remained constant over the various observations with IUE. The TESS lightcurve of HD 78316 reveals a double-wave structure with a rotational period of about 6.25 days. The absence of far-ultraviolet variability and the reproducibility of the brightness in the V band during most IUE observations do not support the presence of large chemical gradients over the surface of κ Cnc at the time of the IUE observations.

A critical review of the distribution of the endangered European earth-borer beetle Bolbelasmus unicornis (Coleoptera, Geotrupidae), with new records from 13 countries and observations on its bionomy
Authors: Juřena Daniel
Published: June 2022

The distribution ofBolbelasmus unicornis(Schrank, 1789) is critically reviewed throughout its range with emphasis on the Czech Republic and Slovakia. The species has been reliably recorded from 377 localities in 19 countries. New records are given from 152 localities of Bulgaria, Czech Republic, Germany, Hungary, Italy, Moldova, Poland, Romania, Serbia, Slovakia, Turkey, and Ukraine. For Germany, the species is recorded for the first time in 54 years. The occurrence of the species in Switzerland is confirmed by two historical specimens from Zürich. The only known historical specimen labelled “Kaukasus” is given, which could originate from Russia, where this species has not been recorded before (however, confusion of the locality label cannot be ruled out). All published faunistic data from across the range are presented here in full, in several cases supplemented by details subsequently obtained by the author. Distribution maps are compiled separately for the Czech Republic and Slovakia, and for the entire range. A separate map is also available for Hungary, where approximately one-third of the known localities are located. Statistical data concerning the flight activity of adults, seasonal dynamics for part of the distribution area, details of records and notes on the bionomy and ethology of the species are provided. Possible feeding strategies for adults and larvae ofB. unicornisare discussed, as well as current knowledge of the natural history of various representatives of the subfamily Bolboceratinae. A monitoring method for the species is proposed.

Finally, we give the numerical simulations to illustrate this method.
Impact of high-standard basic farmland construction policies on agricultural eco-efficiency: Case of China
Authors: Zhu Jinhui , Wang Mengxin , Zhang Changhong
Published: June 2022

The impact of high-standard basic farmland construction policies on agricultural eco-efficiency has been extensively considered. Using the Chinese provincial panel data from 2007–2017, we first measure the level of agricultural eco-efficiency in China by employing data envelopment analysis. Then, using difference-in-difference models, we analyze the impact of high-standard basic farmland construction policies on agricultural eco-efficiency and test whether there is heterogeneity of this impact. Finally, we further explore the specific channels through which the polices of high-standard basic farmland construction affect agricultural eco-efficiency. The empirical results indicate that 1) the implementation of high-standard farmland construction policies can significantly improve agricultural eco-efficiency, 2) the heterogeneity of the impact of high-standard farmland construction policies on agricultural eco-efficiency is manifested in both regional and efficiency aspects and 3) high-standard farmland construction policies promote agricultural eco-efficiency through the interaction between the new land scale and the replanting index.

Authors: Sanchis-Gimeno Juan A. , Hasrod Nabeela , Calvo-Maroto Ana M. , Nalla Shahed , Cerviño Alejandro
Published: June 2022

Background: Corneal changes occur as a direct consequence of diabetes mellitus (DM). The central corneal thickness (CCT) is a useful parameter that provides information about the status of the metabolism of the cornea and can therefore help monitor the progression of DM.Aim: The aim of this study was to determine the impact of DM on CCT and its correlation with diabetes duration and glycated haemoglobin (HbA1c) levels.Methods: The systematic review was undertaken to answer: (1) What effect does DM have on CCT values? (2) What effect does DM duration have on CCT values? (3) What effect does HbA1c levels have on CCT values? The Web of Science was used to conduct a computerised search for articles of CCT values in DM.Results: A total of 38 articles that met the criteria for inclusion were included in this systemic review. The researchers found 27 articles that observed increased CCT values in DM patients compared with control subjects. There were six studies in which increased CCT values were related to DM duration and 12 studies in which DM duration did not alter CCT values. Also, eight studies showed that CCT values increased with glycated haemoglobin levels, and 12 studies did not observe this.Conclusion: Diabetes mellitus patients usually present with increased CCT values although there is no unanimity about the effect of DM duration and increased HbA1c levels (poor glycaemic control) in the CCT values of DM patients.
Realities and challenges for mission transformation in Sabu people
Authors: Widjaja Fransiskus I.
Published: June 2022

Christianity has existed for more than 167 years on the island of Sabu (East Nusa Tenggara). Even though the majority of Sabu people are Protestant Christians, in everyday life, the Sabu people still adhere to the Jingitiu religion’s local beliefs. The value of Christianity is still considered foreign in the appreciation of most people’s faith even though they have become Christians. This research aims to develop the contextualisation of the missiological paradigm in the social culture of the Sabu people in a transformative mission challenge. Furthermore, the method used is a descriptive and qualitative research approach. The results showed the following: (1) the church needs to develop contextual studies (in the light of the Bible) on the cultural understandings of the Sabu people; (2) there is a need to bring together the gospel and culture through traditional activities and (3) the church needs to be proactive in transforming the Sabu people’s traditions as a tool to deliver education, such as moral and ethical education.Contribution: This article aims to assist churches in adopting strategies for inculcating gospel values in the religious traditions and practices of the Sabu people. This approach is proposed to further develop the appreciation of faith through transformation according to gospel values as a support system for proclaiming the message of the Great Commission in transmitting relevant and contextual Christian messages to transform the culture and society of Sabu.
Explanation and interpretation of three unclear words in Bavli Eruvin 104a-b
Authors: Zur Uri
Published: June 2022

This article engages in the explanation and interpretation of three unclear words, dyofe, meiarak and kitana, that appear in the Babylonian Talmud, Tractate Eruvin 104a–b. The words are part of the Talmudic text and the article addresses the various meanings ascribed to them and explains them. This is required because of the contradiction and confusion that exist in the explanation and interpretation of these three words. The research method employed involves examining the various explanations given by the commentators, comparing the words with other sources and checking their suggested meanings in Talmudic dictionaries. The research results show different versions of these three words and the conclusions indicate that the different versions change their possible explanation and interpretation.Contribution: The innovation of this article is in presenting the various sources of these words, noting their various versions and the different interpretations that derive from them. The article also describes the interpretive development of these words, as well as noting the commentators who offer explanations for the two first words, which generate contradictory meanings.

Published: June 2022

Background: The search for bioactive organic products for the treatment of various diseases is a growing concern worldwide, because these bioactive natural products are associated with fewer side effects and are easily accessible.Aim: The present study analysed the phytochemical constituents and cytotoxic effects of the leaf, bark and fruit extracts of Cordia grandicalyx Oberm.Setting: Plant samples were collected from Ga-Mashishimale village in Ba-Phalaborwa Municipality, South Africa.Methods: Antioxidant activity was determined through 1,1-diphenyl-2-picrylhydrazyl radical scavenging method, whilst cytotoxic assay was assessed using the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide method. Plant extracts were subjected to phytochemical profiling using both qualitative and quantitative methods. The extracts were also subjected to fractionation using column chromatography and thin-layer chromatography, and the sub-fractions with considerable yields were identified using nuclear magnetic resonance (NMR).Results: The aqueous extracts of the bark and leaves had significant (p 0.001) antioxidant activity as compared to negative controls and ascorbic acid. Additionally, appreciable amounts of total phenolic and alkaloid contents were recorded on polar extracts, notably 200 mg/GAE and 140 mg/quercetin equivalents for leaf cold water and leaf hot water extracts, respectively. All extracts were not toxic to cells, whilst the positive control (H2O2) led to almost 100% demise of cells. Two compounds were isolated from the leaf acetone extracts collected from fraction 20 to 30 and fraction 101 to 120 and identified as α˗amyrin and β-amyrin by NMR spectral analysis.Conclusion: The study provided evidence supporting the screening of plants for the discovery of therapeutic compounds. The study also revealed that all the different C. grandicalyx extracts were less toxic to cells and may provide scientific backing for continued use of the plant in mixtures for the treatment of diseases.
Battery Electric Vehicles Energy Consumption Breakdown from On-Road Trips

Authors: Tansini Alessandro , Di Pierro Giuseppe , Fontaras Georgios , Gil-Sayas Susana , Komnos Dimitrios , Currò Davide
Published: June 2022

Battery Electric Vehicle (BEV) sales have been spiking up due to a series of factors: zero tailpipe emissions, wider model availability, increased customer acceptance, reduced purchase price, improved performance and range. The latter is a crucial factor the consumers consider when purchasing a BEV, and it largely depends on how the vehicle operates (e.g. average speed), traffic, ambient conditions, and battery size. When driven on the roads, the actual range of BEVs can be significantly smaller than the certified value obtained from laboratory testing at standard conditions. To understand the factors influencing vehicle range in real-world operation, the study team performed on-road tests on three production passenger vehicles currently available in the European market. The measured quantities, including vehicle signals from OBD/UDS, were used to quantify the vehicle energy consumption. Global Navigation Satellite System (GNSS) data was used to calculate vehicle positioning and resistances, including altitude. Findings show an average consumption of 201.5 Wh/km for mid-sized passenger cars, ranging between 150 to 293.4 Wh/km (minimum and maximum observed values from a B-Segment vehicle and a 9-Seater VAN, respectively). Ambient temperature is one of the factors introducing a high variability in real-world energy consumption, as electric energy is used both for cabin heating and cooling, which might lead to range reductions of 30-50 % under extreme conditions. An energy breakdown is presented for each trip, describing the typical share of propulsion, cooling/heating needs and other auxiliaries.

The implementation of emission standards has brought significant reductions in vehicle emissions in the EU, but road transport is still a major source of air pollution. Future emission standards will aim at making road vehicles as clean as possible under a wide range of driving conditions and throughout their complete lifetime. The current paper presents the methodology followed by the Consortium for ultra LOw Vehicle Emissions (CLOVE) to support the preparation of the Euro 7 proposal.

As a first step, the emission performance of the latest-technology vehicles under various driving conditions was evaluated. Towards this direction, an emissions database was developed, containing data from a wide range of tests, both within and beyond the current RDE boundaries. The results revealed that harsh accelerations, extreme ambient temperatures, very short trips (particularly at urban conditions), DPF regeneration and uphill driving, or combination of those conditions, can result to high emissions. Next, suitable technology packages to address such high emissions were defined and evaluated, using simulation models. On top of this analysis, additional elements were assessed, namely on-board emissions monitoring, additional species to be regulated and instrumentation for future on-road emission testing.

The overall analysis revealed that existing state-of-the-art emission control technologies can achieve very low emission levels, but not under all driving conditions. Thus, additional improvements and potential new technologies are needed to bring ultra-low emissions. These technologies include larger exhaust aftertreatment devices, optimized engine and aftertreatment thermal management (mainly during cold-start) and further penetration of electrification. Particularly the latter is heavily enforced by the CO2-related measures and can strongly support the limitation of pollutant emissions, as well.

Published: June 2022

The length-weight relationship and condition factor of Sarotherodon melanotheron and Tilapia guineensis inhabiting Lagos lagoon were examined and the relationship among the parameters was determined by correlation. The mean total length and weight was 16.33±2.24cm and 71.44±30.04g for S. melanotheron and 16.08±2.92cm and 84.93±44.24g for T. Guineensis, respectively. The regression coefficient (b) of length and weight revealed that S. melanotheron exhibited negative allometry (b=2.36; a=-2.39; R2=0.67) while T. guineensis exhibited positive allometry (b=3.19; a=-4.54; R2=0.87). The condition factor which measures the physiology (wellbeing) of fish was greater than 1 for the two species although, it was higher in T. guineensis (2.04) than S. melanotheron (1.64). This difference may be due to variation in the weights of the two fish species as well as environmental factors in the lagoon. The study revealed that both species were healthy despite that Lagos lagoon receives wastewater from different anthropogenic sources. This shows that the study area is conducive for the development and sustenance of fisheries resources.

L’objectif de ce travail était de mener une enquête ethnobotanique dans quatre marchés des zones soudanienne (Bamako et Sikasso) et sahélienne (Banamba et Kolokani) du Mali afin de recenser les fruits de cueillette vendus et leurs usages médicinaux. L’enquête a été réalisée à l’aide de questionnaires et d’entretiens auprès des vendeurs de fruits. Les résultats ont montré que vingt-deux fruits de cueillette appartenant à dix-sept familles faisaient l’objet de commerce dans les marchés enquêtés et que la cueillette et la vente de ces fruits sauvages étaient une activité largement dominée par les femmes (88%). Les familles des Arecacées, Annonacées, Apocynacées et Fabacées étaient les plus représentées. Les fruits de Balanites aegyptiaca, Zizyphus mauritiana et Saba senegalensis étaient les plus cités. Six des vingt-deux fruits vendus (27,27%) : Lannea microcarpum, Parkia biglobosa, Saba senegalensis, Tamarindus indica, Vitellaria paradoxa, Zizyphus mauritiana étaient communs aux marchés des quatre villes. Il ressort également que ces fruits étaient non seulement consommés pour les besoins nutritionnels mais aussi pour la prise en charge traditionnelle de certaines pathologies (hypertension, diabète, paludisme, stérilité, etc.). Ces résultats constituent une base de données pour d’autres travaux visant à évaluer les potentialités nutritionnelles et antimicrobiennes de ces fruits.

L’urbanisation engendre le plus souvent l’altération des écosystèmes. La conséquence ultime est la disparition de nombreux massifs forestiers et la simplification des écosystèmes. Cette étude avait pour objectif d’évaluer les répercussions de l’urbanisation sur les écosystèmes forestiers de la ville de Douala. Des enquêtes semi-structurées participatives ont été réalisées auprès de 94 ménages à Logbessou et à Lendi associées aux recherches documentaires et à l’analyse des cartes d’occupation du sol. De même, des inventaires floristiques ont été effectués. L’analyse des données a montré de nombreuses transformations spatio-temporelles dans la zone d’étude. De nos jours, Douala compte un total de 22 451 ha d’espaces agglomérés avec une évolution de 2,4% par an et un total de 3 347 500 individus dont le rythme de croissance est de 1,7% par an. 67 espèces végétales distribuées dans 57 genres et regroupées au sein de 38 familles ont été recensées. Les zones à urbanisation avancée possédaient les plus forts taux d’espèces avec respectivement 29, 34 et 26 espèces. Dans la zone périphérique à faible urbanisation, 20 espèces ont été recensées. Le tissu urbain de la ville de Douala et la taille de sa population évoluent à un rythme croissant au détriment des forêts.
Streamlining civil - military education for national development in Nigeria
Authors: Dii Christian Tsaro
Published: June 2022

The National Policy on Education in Nigeria defined tertiary education as the education given after secondary education. By that definition, all professional military training education in the country are tertiary education being post-secondary education. However, despite the rigorous, systematic and methodical trainings offered by military personnel, their certificates are not recognized as tertiary education certificates outside the military and as such retired personnel found themselves unemployable after military career and unable to participate in any meaningful national development activities. Using a qualitative research approach based primarily on social constructivism perspective, this paper sets out to investigate how to achieve equivalence between military training and civil tertiary education certificates to enhance national development in Nigeria. The basic assumption of the paper was that without integrating military and civil education certificates, retired military personnel cannot contribute to national development which constitutes colossal waste of highly trained human resources in the country. The findings showed that all military training courses’ certificates can be recognized if the military authorities will initiate the procedures of getting their training curriculum adjusted and discussed at the National Council on Education. The paper recommended that the Office of the Chief of Defence Staff should initiate the engagement of all relevant stakeholders to discuss military training curriculum and seek the accreditation of all the courses accordingly.

Published: June 2022

This paper investigates the determinants of loyalty for low income earners in emerging markets. A survey of 287 customers of specialized banks (banks built for low income earners) in Abakaliki Nigeria was conducted. The hypotheses under study were tested using factor and regression analysis. The results from the test show that determinants of customer loyalty include satisfaction, trust as well as perceived service quality. However, corporate image is not a determinant of customer loyalty. This study offers important implications to researchers as well as practitioners and highlights the insignificance of the company’s image to customer loyalty which is a basis for further studies. In the Nigerian societal context, corporate social responsibility (CSR) which in turn gives rise to corporate image is viewed as an act of philanthropy and mostly carried out by most multi-national companies (MNCs). The CSR programmes of these Multi-nationals mimic the CSR programmes of western economies neglecting local realities and the peculiarities of the Nigerian diverse economy occasioned by socio-economic challenges.
