Authors: Olaniyan Olatayo Moses , Adetunji Olusogo Julius , Fasanya Adedire Marquis
Published: October 2023

Lumpy skin diseases virus (LSDV) is a dangerous and contagious diseases that are mostly common in Sub-Saharan African, South Eastern Europe, South Asia and as well as Middle East, China.  LSDV is transmitted through blood sucking insects which are double stranded DNA virus and belong to the family of Capri poxvirus genus family. The recent study proved and clarified that lumpy skin diseases viruses (LSDV) affected mostly cattle and buffalo in Africa, Asia and Europe with population of 29 966, 8 837 and 2 471 outbreaks respectively, between the years 2005 – 2021. Different machine learning approaches have been adopted for the prediction of lumpy skin diseases. An enhanced model was developed to improve the predictive performance of existing model and also, compared the performance of stacked ensemble of single classifiers with respect to optimized artificial neural network.  The implementation was done with python 3.7 on Core i5, 16G RAM Intel hardware.  The single classifiers are decision tree (DT), k-nearest neighbor, random forest (RF) and support vector machine (SVM). A feature wiz feature selection technique was adopted on lumpy skin diseases dataset coupled with the parameters tuning of the model before classification. Both stacked ensemble and optimized artificial neural network model outperformed the existing model. Stacked ensemble model gives accuracy, precision, f1-score and recall of 97.69%, 98.44%, 98.93% and 98.68% respectively. The results also showed that optimized artificial neural networks of 200 epochs outperformed stacked ensemble classifiers with accuracy of 98.89% and 98.66% of training and validation respectively. The developed model in a real world would assist in reducing the occurrence of lumpy skin diseases.

Flood disaster is a natural disaster that leads to loss of lives, properties damage, devastating effects on the economy and environment; therefore, there should be effective predictive measures to curb this problem. Between the years 2002- 2023, flood has caused death of over 200,000 people globally and occurred majorly in resource poor countries and communities. Different machine learning approaches have been developed for the prediction of floods. This study develops a novel model using convolutional neural networks (CNN) for the prediction of floods. Important parameters such as standard deviation and variance were incorporated in the parameters tuned CNN model that performed flood images feature extraction and classification for better predictive performance. The enhanced model was assessed with accuracy and loss measurement and compared with the existing model. The model leverage on the unique features of region of Interest aligns to resolve the issues of misalignments caused by the use of region of Interest pooling engaged in the traditional Faster-RCNN. The techniques and the developed system were implemented using a Python-based integrated development environment called “Anaconda Navigator” on Intel Core i5 with 8G Ram hardware of Window 10 operating system. The developed model achieved optimal accuracy at 200 epochs with 99.80% and corresponding loss of 0.0890. The results confirmed that predictive performance of a model can be improved by incorporating standard deviation and variance on model, coupled with its parameters tunning approach before classification.

Prior’s early reflections on sense and sentences
Authors: Grimshaw Mike , Jakobsen David
Published: October 2023

We present here an introduction and a discussion of A.N. Prior’s ‘Sense and Sentences’ in light of the context of publication in the journal National Education, written upon his return from Europe and while he was undergoing a crisis of faith. We argue that ‘Sense and Sentences’ is the article referred to by Kenny in his Obituary on Prior as an article written “on the relations between logic and grammar (with reference to Popper, Wisdom and Carnap)”. Furthermore, we argue that Prior was working his way into philosophy, by demonstrating his familiarity with the work of key persons within analytic philosophy such as Rudolf Carnap, John Wisdom and Karl Popper. We also argue that Findlay’s – and, thus, indirectly: Wittgenstein’s – influence is also visible in this period where Prior was transitioning from being a religious journalist to the future philosopher he would turn out to become. In particular, we argue that, while Findlay’s influence on the relationship between grammar and metaphysics would win the day with A.N. Prior, when he discovered tense-logic, it was not an evident feature of Prior’s work on the relationship between logic and grammar in sense and sentences. We argue that Sense and Sentences is interesting because it seems to have expressed a stage in Prior’s thinking on logic that he later came to modify, thereby distancing himself more from the anti-metaphysical tenets of analytic philosophy.
Łukasiewicz, Bocheński, and Feys: Their Impact on the Early Prior
Authors: Copeland B. Jack , Markoska-Cubrinovska Aneta
Published: October 2023

We investigate how Arthur Prior became a tense-modal logician, and which moderns influenced him in his early thinking about modality. His unpublished manuscript The Craft of Formal Logic, written in the period 1949–51, is in effect a record of his rather isolated apprenticeship as he trained himself in formal logic, during the two years before the commencement of his torrent of publications on modality. We analyse sections of this rich record of his logical development, especially those dealing with modal logic, and we extract a detailed account of the pattern of influences exhibited in The Craft. The Craft reveals that Prior’s first encounters with modern symbolic modal logic were the pioneering explorations by Bocheński, Feys, and Lewis. Von Wright was also an early influence. It was through Bocheński’s writings that Prior learned of Łukasiewicz’s approach to modality, and Łukasiewicz’s work quickly became a beacon for Prior. The roles of Lewis and von Wright appear to have been smaller than those of Łukasiewicz, Bocheński, and Feys—hence our focus on these three figures. As well as biographical material on these three outstanding logicians, we include numerous previously unpublished passages from The Craft in order to establish the nature and extent of their impact on Prior.

Authors: Maier Stephen P. , Prabhat Anjali M. , Collins Jamie E. , von Keudell Arvind , Earp Brandon , Zhang Dafang
Published: October 2023

Introduction:

Reverse total shoulder arthroplasty (RSA) is used to treat a variety of shoulder-related pathologies. This study compared medium-term clinical outcomes of less than 10-year follow-up in patients treated with RSA for proximal humerus fracture (PHF) versus rotator cuff arthropathy (RCA).

Methods:

This retrospective review was conducted at two tertiary care centers, in which self-reported clinical outcomes were assessed using four validated instruments, that is, American Shoulder and Elbow Society (ASES) score, Shoulder Pain and Disability Index (SPADI), visual analog scale (VAS), and shoulder subjective value (SSV). Statistical analyses were performed using linear or logistic regression with generalized estimating equations.

Results:

Of the 189 patients included in this study, 70 were treated for fracture and 119 for RCA. At a mean postoperative follow-up of 6.4 years, the means were 79.7 for ASES score, 20.8 for SPADI-Total, 0.8 for VAS, and 77.1 for SSV. After adjusting models for covariates, there was no significant difference in average SSV (P = 0.7), VAS (P = 0.7) or SPADI-Pain (P = 0.2) between PHF and RCA cohorts; however, the RCA cohort reported significantly better outcomes in ASES scores (P = 0.002), SPADI-Disability (P < 0.0001), and SPADI-Total (P = 0.0001).

Discussion:

Patients with RCA and PHF treated with RSA achieved similar medium-term outcomes in several domains, particularly postoperative pain levels; however, patients with PHF reported greater perceived disability. RSA is an effective pain-controlling procedure, but patients may have variable functional outcomes based on the indication for surgery.

Интерметаллическое соединение Ni3Fe получено методом синтеза горением растворов (СГР), основанным на нагреве водного раствора, содержащего нитраты соответствующих металлов и гексаметилентертамин (ГМТА) в среде азота. Определены пределы осуществления самораспространяющейся реакции в системе нитраты металлов–ГМТА в зависимости от количества последнего в реагирующей смеси (n). Установлено, что изменением величины n можно регулировать фазовый состав и микроструктуру получаемых продуктов процесса СГР. Рентгенофазовым анализом показано, что при n = 6 получается однофазный целевой продукт Ni3Fe, а электронно-микроскопические исследования свидетельствуют, что полученный продукт характеризуется ярко выраженной пористой структурой, обусловленной обильным газовыделением по ходу СГР. По результатам термогравиметрического анализа как индивидуальных соединений, так и смеси реагентов (нитратов железа и никеля с ГМТА) обсуждается возможный механизм образования целевого интерметаллического соединения Ni3Fe. Исследованы магнитные характеристики синтезированного вещества.
The intermetallic compound Ni3Fe was obtained using the solution combustion synthesis (SCS) method, based on heating an aqueous solution containing nitrates of the corresponding metals and hexamethylenetertamine (HMTA) in a nitrogen atmosphere. The limits for the implementation of a self-propagating reaction in the metal nitrates - HMTA system were determined depending on the amount of HMTA in the reacting mixture (n). It has been established that by changing the value of n it is possible to control phase composition and microstructure of the obtained products of the SCS. X-ray examinations have shown that at n=6, a single-phase target product Ni3Fe is obtained, and electron microscopic studies indicated that the product is characterized by a pronounced porous structure, due to abundant gas evolution during the SCS process. Based on thermogravimetric analyses of both the individual compounds and the mixture of reagents (iron and nickel nitrates with HMTA), a possible mechanism for the formation of the target Ni3Fe intermetallic compound is discussed. The magnetic characteristics of the synthesized substance have been studied.

Atividade coletiva, atividade em comum, labor conjunto: Aproximações ao conceito de coletividade
Authors: Zeferino Lidiane Chaves , Romeiro Iraji Oliveira , Moretti Vanessa Dias
Published: October 2023

Nesse artigo, analisamos como duas teorias de base histórico-cultural discutem o papel da atividade coletiva em suas proposições: a Teoria da Objetivação (TO), proposta por Luis Radford e a Atividade Orientadora de Ensino (AOE), proposta por Manoel Oriosvaldo de Moura. Partimos do conceito de atividade na teoria histórico-cultural e sua relação com o conceito de trabalho em Marx, e apresentamos a compreensão de coletividade nas obras de Makarenko e Petrovski. A partir desses embasamentos discutimos a ideia de atividade coletiva, tal como assumida pela AOE e a ideia de labor conjunto, como proposta pela TO. Na análise da atividade coletiva como proposta pela AOE, mostra uma convergência entre tal conceito e a compreensão de trabalho coletivo uma vez que a atividade, tomada conforme Leontiev, dialoga com o conceito de trabalho em Marx. A análise do labor conjunto assumido na TO, remete a uma categoria que implica no trabalhar de forma compartilhada e engajada visando a produção de uma obra comum, convergindo com a ideia de atividade coletiva. Concluímos que apesar das especificidades dos construtos teóricos próprios de cada uma das teorias estudadas, reconhecemos aproximações no tocante aos conceitos analisados: atividade coletiva (na AOE) e labor conjunto (na TO).

Authors: Li Jiatao , Tong Jian , Jiang Zhewei , Chu Ningwan
Published: October 2023

This article aims to evaluate the policy effect of the childcare policy on family women's career development using microdata collected from Nanchang and Jiujiang during 2017-2021. The study finds that the career development index of family women in the pilot areas is significantly higher than that in the non-pilot areas, indicating that the childcare policy significantly promotes the career development of family women. Furthermore, this article conducts robustness tests by delaying the control variables by one period and shortening the sample range, verifying the stability of the regression results. Additional analysis shows that the childcare policy mainly affects family women's career development by accumulating women's human capital in terms of health. The findings of this article provide important policy implications for China to further improve childcare services in the field of childcare.

Authors: Zhang Weijie , Xie Yuxin , Zhang Yuanpeng , Ai Jiawei
Published: October 2023

To achieve the goal of "double carbon" is the only way for our country to achieve emission reduction strategy. The Yangtze River Economic Belt is one of the strategic support belts for emission reduction, so it is of great significance to study the decoupling effect of energy and carbon emissions. Based on the carbon emission data of the Yangtze River Economic Belt from 1995 to 2021, this paper firstly analyzes the basic characteristics and spatial pattern of carbon emission in the Yangtze River Economic Belt. Secondly, a spatial econometric model is constructed to decompose the main influencing factors of carbon emissions in the Yangtze River Economic Belt, and the main influencing factors of economic and energy decoupling in the Yangtze River Economic Belt are explored by using the canonical correlation analysis method. Finally, BP neural network is used to forecast and analyze the carbon emission of the Yangtze River Economic Belt from 2022 to 2030. The results show that: (1) The center of gravity of carbon emissions in the Yangtze River Economic Belt is gradually shifting to the southeast, and there is a spatial correlation between regional carbon emissions. (2) The strong influencing factors of carbon emission in the Yangtze River Economic Belt are industrial composition and development differences; The influencing factors are city size and resource consumption intensity. The weak factor is the level of energy #consumption. The level of energy consumption and industrial composition are the main influencing factors of economic and energy decoupling in the Yangtze River Economic Belt. (3) Carbon emissions in the Yangtze River Economic Belt will continue to grow from 2022 to 2030, and will grow fastest from 2029 to 2030.
Scrutinizing Portfolio Strategies and Asset Pricing Models: The French Case
Authors: AyA NAsreddiNe  , SouAd LAjiLi jArjir
Published: October 2023

On the basis of 25 size/book to market and 25 size/momentum portfolios and over the1981-2013 period, this study gives robust results about the characteristics of French stockmarket returns with different asset pricing models (CAPM, Fama and French (1993) threefactor and Carhart (1997) four-factor models). The four-factor model accounts better forcommon variation in stock returns, but it adds little compared to the three-factor one.Moreover, size, value and momentum effects are more significant when stock marketsare febrile. Furthermore, except for loser portfolios, asset pricing models are more relevant for big rather than small capitalizations. Using the Gibbons, Ross and Shanken (1989)test, market, size, value and momentum factors explain stock returns better than one andthree-factor models. Except the four factor model, we reject all other tested asset pricingmodels. A better proxy for the market portfolio is the value-weighted portfolio of all stocks.

This paper study CAC 40 historical volatility in long run perspective (using intradayand interday data between 1990 and 2016 and on monthly data from 1914). Despite thedevelopment of high-frequency trading and a very frequent reference to high volatilityin new media, the volatility of CAC 40 does not reach any historical summits duringthe 2010s. The most volatile periods are those identified – using the windows method(Mishkin and White) – during periods of financial crisis. Our results are in line withSchwert measurement of US stock market volatility and invite to consider macroeconomicfundamentals volatility in order to explain stock market high volatility (Shiller,Hansen and Jagannathan).
The cross-border strategies of European banks: Effects on performance
Authors: JESSY TROUDART  , ERIC LAMARQUE
Published: October 2023

Are the cross-border strategies of European banks effective? Over the period from2007 to 2012, banking systems experienced some important transformations in severaldimensions including the international expansion, especially in OECD countries. However, European banks further continued their trend of increased foreign bank ownership between 2007 and 2012. Besides, the share of foreign banks assets in Europeanarea remains the same before and after the crisis in 2012 (about 80 % according to thereport of the IMF in 2013). This is mainly due to the regionalization context in whichEuropean banks operate. Therefore, this paper is motivated by an intense internationalization in the banking sector from the beginning of this century until 2012. Afterfive years of consolidation of equity capital and bank stability, many banks considernow again the opportunity to go abroad. We investigate whether the various optionsfor expanding overseas have a positive impact on the profits of European banks. Weanalyse the results in which 42 European banks might expect expansion abroad thoughsubsidiaries, conducting cross-border acquisitions, or forming cross-border partnerships, during the period 2004–12. We find that extending international operationsthrough subsidiaries could have a negative impact on profits, whereas cross-borderpartnerships could improve them.
CSR Performance, Dividend Payout and Governance Mechanisms
Authors: GUILLAUME PIJOURLET
Published: October 2023

In this article, we study whether Corporate Social Responsibility (CSR) performancehas an influence on dividend payout ratios. We provide evidence that high CSR firmspay more dividends than other firms. We also find that the positive relationshipbetween CSR performance and dividend payout is observed only for firms in highinvestor protection countries, for firms with high insider ownership, and with highanalyst coverage. These findings provide support for the agency view of CSR whichposits that CSR activities may be related to the managerial expropriation of shareholders. Dividend policy seems to be a tool used to mitigate this problem. Hence, inaccordance with the “outcome model” of dividend policies, we highlight that the linkbetween CSR performance and dividend payout is significant only when internal orexternal governance mechanisms are strong. This indicates that dividend policy andgovernance mechanisms are complementary and not substitute mechanisms to limitpotential expropriation linked to CSR policies.
Why do firms issue green bonds?
Authors: FRANCK BANCEL  , DEJAN GLAVAS
Published: October 2023

The first green bond was issued by the European Investment Bank in 2007. Since then, the market has sharply increased from a less than USD1bn annual issuance to a higher than USD100bn annual issuance between 2007 and 2017. In this article, we investigate drivers of the green bond market’s success. We first look at whether green bonds benefit from any direct or indirect economic benefit as compared to non-green bonds. We then more deeply investigate the motives of firms deciding to issue green bonds. Aside from economic benefits, we show that firm characteristics, as well as the environment-related regulatory context, are key drivers of green bond issuance.
Did The Global Financial Crisis Alter Cross-market Correlation? A Copula-GARCH Approach
Authors: ZAYATI MONTASSAR , BEN MIM SAMI
Published: October 2023

This paper uses a wide variety of copulas to study the correlation between the US market and a sample composed of nine developed and emerging markets over a 13 years period, including the subprime crisis. We try to analyze the markets behavior during high volatility periods and assess if the financial crisis led to a significant and durable change in the cross-market correlation patterns. Results offer strong evidence in favor of a contagion effect. Developed markets are those who registered the most important increases in cross-market correlations during high volatility periods. This may be attributed to their high degree of financial integration. However, cross-market correlation is weak for the whole sample period and decreased during the post-crisis period, implying that international diversification still offers interesting opportunities for investors. Moreover, diversification opportunities are not restricted to emerging markets but also concern developed markets.
Does corporate innovation strategy influence stock price crash risk? French market evidence
Authors: BOUBAKER SABRI , GUIZANI ASSIL , LAKHAL FATEN
Published: October 2023

The purpose of this paper is to examine the effect of corporate innovation strategy on firm-level stock price crash risk. Using a sample of French listed firms covering 2007–2016, we show that innovative firms are more prone to future stock price crash risk. Managers of these firms have optimistic expectations about growth prospects that encourage them to hide bad news, leading to higher stock price crash risk. This positive relationship is only prevalent in competitive product markets and with low analyst coverage suggesting that innovative firms are likely to experience stock price crashes when information asymmetry is exacerbated. Our results stand up to several robustness tests and remain unchanged after addressing endogeneity concerns.

This paper investigates volatility spillovers among six competitor Cryptocurrencies from August 8, 2015 to September 01, 2019. A Generalized VAR framework is used to measure time varying spillovers index. Results provide evidence of (i) a rise in volatility spillovers transmitted among monitored Cryptocurrencies since the second quarter of 2017. (ii) Ethereum acts as the major contributor on spillovers index, contrary to Ripple that presents the main recipient of spillovers. (iii) the pairwise (Monero-Ripple) and (Bitcoin-Ethereum) present a low connectedness level driving consequently beneficial diversification opportunities for cryptocurrency investors.
Social media use in adolescent girls with depression: The relationship between social media use purposes, lack of social support, and cyber victimization
Authors: Göksu Muhsine , Rodopman Arman Ayşe , Gündoğdu Ümmügülsüm , Gümüştaş Funda
Published: October 2023

Objective: Our study examined the relationship between purpose of social media use, perceived social support, and cyberbullying
among adolescent girls with or without major depressive disorder (MDD).
Patients and Methods: Fifty-two adolescent girls aged 13-18 years with a diagnosis of MDD were recruited. The control group consisted
of 51 adolescents who were matched for age and gender. The adolescents completed a sociodemographic form, the Childhood
Depression Inventory (CDI), the Social Media Attitude Scale (SMAS), the Cyberbullying Scale (CBS), and the Social Support Appraisal
Scale for Children (SSAS).
Results: Social media use was significantly higher among adolescent girls with MDD (P<0.001). They had significantly higher social
isolation (P=0.006) and cyberbullying scores (P=0.013). They used more social media for social skills (P<0.001) and their perceptions
of social support levels were lower than adolescents without MDD (P<0.001). Cyberbullying was inversely related to perceived social
support (P=0.015) and positively related to social media use for social competence (P=0.004) (e.g., satisfying the need for esteem).
Conclusion: This study suggests that increases in social competence problems and decreases in perceived social support were associated
with being a victim of cyberbullying. In depressed adolescents, cyberbullying can be prevented by interventions aimed at promoting
social competence and obtaining sufficient support.

Chất lượng và tổng chi phí các dự án luôn là vấn đề được quan tâm hàng đầu trong công tác xây dựng. Chi phí đầu tư xây dựng phải được tính đúng, tính đủ theo từng dự án, công trình, gói thầu phù hợp với yêu cầu thiết kế, điều kiện xây dựng và mặt bằng giá thị trường. Hiện nay, Nhà nước cũng đã ban hành các quy định, hướng dẫn về lập và quản lý chi phí tương đối rõ ràng, chi tiết. Tuy nhiên thực tế còn nhiều bất cập, gây khó khăn trong quá trình thực hiện, như công tác xác định chi phí quản lý dự án và chi phí tư vấn đầu tư xây dựng theo định mức tỷ lệ còn nhiều vướng mắc; công bố giá vật tư tại địa phương chậm, chưa sát thực tế; định mức dự toán xây dựng chưa hoàn thiện. Xuất phát từ thực tiễn tham gia thực hiện công tác tư vấn lập và quản lý chi phí đầu tư xây dựng, nhóm tác giả chia sẻ một số vướng mắc trong công tác này. Với mong muốn đóng góp ý kiến để các quy định, hướng dẫn của Nhà nước về xây dựng cơ bản ngày càng chất lượng, nhanh chóng đáp ứng được yêu cầu phát triển của xã hội.

Nghiên cứu này tập trung vào việc đánh giá khả năng nứt ở độ tuổi ban đầu của bê tông thường (NC) và bê tông cường độ cao (HC) bằng phương pháp vòng kiềm chế, nhằm cung cấp cho việc dự đoán khả năng ứng xử của từng loại bê tông để từ đó đưa ra những biện pháp thi công phù hợp cho công trình xây dựng. Hai loại bê tông được khảo sát bao gồm NC với mác thiết kế M350 và HC với mác thiết kế M600. Kết quả thực nghiệm đã chỉ ra rằng khi so với NC, HC có tốc độ co ngót nhanh hơn trong 24 giờ đầu, và tăng rất chậm trong những ngày sau đó. Vết nứt xuất hiện trong HC thường xảy ra rất sớm khi so sánh với NC. Khả năng nứt của bê tông có thể được đánh giá dựa trên thời điểm nứt hoặc tốc độ phát triển ứng suất kéo theo thời gian của bê tông, không phụ thuộc vào loại bê tông. Kết luận rằng, việc dự đoán khả năng nứt trong mỗi loại bê tông thông qua thí nghiệm vòng kiềm chế mang tính khả thi để từ đó có thể đưa ra nhiều biện pháp thi công phù hợp khi áp dụng từng loại bê tông trong xây dựng.

Open Data: A National Data Governance Strategy For Open Science And Economic Development – A Case Study Of The United Arab Emirates
Authors: Ekundayo Tosin , Isaac Osama
Published: October 2023

Open science is data-based endeavor. It requires scientific collection and analysis to arrive at findings, that explains a phenomenon. Data are either primary or secondary. In a post pandemic world, restrictions are posing challenges to the collection of primary data for scientific analysis purpose. This is due to limited financial and/or time resources and/or some form of social distancing. A sustaining alternative for open science program is secondary data. These are data collected by a credible source like government and reputable organizations (Chinelo Igwenagu, 2016; Morgan & J.Harmon, n.d.). How accessible are open data for open science in the MENA region? The difficulty and/or unavailability of data poses a challenge to open science practices in the MENA region. This paper intends to investigate open data for open science and economic development in the United Arab Emirates (UAE) as a leading country in the MENA region. The aim is to identify the region’s open data and open science gaps based on the Open Data Barometer (ODB) framework and proffer insight for optimization, using the national data governance approach of Open data as per the Open Data Charter (ODC) principles of 2015. This study reviews a 63 randomly selected list of government entities & ministries open data practices in the UAE. Potential findings will help assess open data and open science strategy in the region. This is significant because it will draw the attention of MENA government and stakeholders to the gaps and opportunities in the revival of a post pandemic economy. It could also serve as a model for other MENA nations in their pursuance of all-round development.

The study was carried out to determine the effect of cutting time, IBA and putrescine treatments on the rooting of the cuttings of Tombul hazelnut cultivar. The plant material of study consisted of cuttings prepared from one-year-old root sucker of Tombul hazelnut cultivar. The cuttings collected on three different dates (15 June, 10 July and 4 August) were performed three treatments (control, 2000 ppm IBA and 2000 ppm IBA+1600 ppm putrescine). Depending on the interaction of cutting time and treatment, the highest rooting was determined in the cuttings treated IBA collected in June (16.7%), while the lowest in the control cuttings (0%) in all periods. Except for the cuttings treated IBA+putrescine collected in August, callus did not occur in other treatments. The number of roots per cutting was determined between 0.0 (control in all applications) and 15.5 (taken in July and IBA applied). Root length was measured from 0.0 (control in all applications) to 8.0 cm (received in June and IBA applied). The best results in rooting level were recorded in cuttings treated IBA collected in July (4.0). The best results in terms of rooting and root properties of cuttings of Tombul hazelnut cultivar were generally determined in cuttings treated IBA collected in June.

Published: October 2023

The study was conducted to assess locally available chicken feed resources and feeding trends in the Karat zuria district of the Konso zone and Derashe special district. Multi-stage sampling techniques were used and a total of 120 respondent farmers from the districts who possess chicken production were involved. The data were collected by questionnaire, personal observation, and interviews. Potential cereals: sorghum (95.0±0.22% and 86.7±0.34%), teff (65±0.48% and 66.7±0.48%) from pulses haricot bean (58.3±0.50% and 45.0±0.50%); as vegetables Moringa stenopetala locally: Halako (96.7±0.18 and 91.7±0.28) in Karat zuria and Derashe special districts, respectively were identified as commonly locally promising human food as well as chicken feeds. Cooked food scraps (Fosase, Kurkufa); kitchen wastes, and protein sources (growing worms, termites, insects, grasshoppers, flies) local brewery residues (Cheka residues) were highly ranked as potential scavengeable feed resources (SFR) in both districts. However, January to May is the major month of the year severity of feed shortage (90% of respondents) mostly occurred. About 2/3 of farmers spreading the grain on the bare ground together for the whole groups of chicken once per day mainly for egg yield (41.67% of respondents) in the area was a very common trend of providing supplementary feed. Consequently, efforts have to be made to design and implement interventions, aiming at improving chicken feed resource base and feeding trends.

Blended learning is a driving force behind new pedagogical approaches. While many studies have shown the positive effects of blended learning on the students’ learning outcomes, the extent and breadth of its sustainability remains an interesting question, given the rapid evolution and diversification of technology post COVID-19 pandemic. In this study, we examined the ratio of technological interventions in blended learning studies, and their corresponding students’ feedback by categorizing 37 compliant articles. With a defined set of inclusion and exclusion criteria, and a clear search strategy, we employed systematic reviews to comprehensively and systematically identify, evaluate, and synthesize relevant evidence to probe on a specific research question. The results advocate the notion of ratio, regardless of its specific percentages, predominantly proffering positive feedback, indicating that the integration of technology is essential for supporting sustainable strategies in teaching and learning approaches. Overall, these findings provide a comprehensive body of high-quality evidence that blended learning has the potential to meritoriously support sustainable education model. It has significant practical significance in addition to its implications for empirical research. Additionally, it produces structured guidelines as a result of its thorough analysis, which may help to accelerate the adoption of blended learning.
The Dual Nature of Hyperreality in the Age of Artificial Intelligence
Authors: Zafar Mahnoor
Published: October 2023

This article explores the interconnectedness of hyperreality with the new era of artificial intelligence (AI). Jean Baudrillard's concept of hyperreality dates back to the nineteenth century when it was considered a provocative and eccentric notion. In the current digital era, this concept gains prominence as media portrays hyperreal images, making AI-powered technologies amplify the world's realism beyond its actuality. Today, reality is a fusion of physical and virtual realities, human existence and artificial intelligence (AI). Amid the numerous challenges the world faces, artificial intelligence has the potential to be more destructive and perilous than any nuclear weaponry.

Authors: Ohia Dr. Ben-Fred
Published: October 2023

The whole world in Ogba cosmology exists for man’s sake and the universe is divided into two: the visible and invisible parts (the heaven or sky and the earth). The sky is the invisible as well as the underworld that is below the earth, while the earth is visible part. Ogba people believe in the link between earth and heaven which they reflect in their oral traditions. This paper analyses the oral tradition of the Ogba people; their origin, religion, belief system and their functions and relevance to human experience. And to achieve this, a brief analysis of Ngugi Wa Thiongo’s Devil on the Cross and Chinua Achebe’s Thing Fall Apart are used as oral traditional novels. The paper comprises the introduction, themes and languages of the oral tradition, the oral tradition of Ogba people, an overview of the oral tradition and finally conclusion. The paper discovers that oral tradition features prominently in the works of African writers; explaining in details the culture milieu as perceived in festivals, dances, funerals and songs. The paper focuses on the aesthetic values of the Ogba cosmology using ethnopoetics and historicism as a theoretical framework. The paper finds out that the oral tradition of Ogba people is a unifying force that brings the people together to live in peace, unity and love.
