Sustainable Social Innovation in Nigeria
Authors: Oni Oluwasola
Published: July 2023

Purpose: Innovation is a constant state of affairs, in order for development to continue. However, there is also a need to ensure that innovations are sustainable. To this end, the paper examines the challenges that may hinder the achievement of sustainable social innovation in Nigeria and explores possible solutions and opportunities for development.
 
Design/Methodology/Approach: The author conducted normative research that examined existing research with the aim of providing solutions to a research area that is fraught with challenges and also currently under researched. Research was also conducted for documents and research from previous studies which were subsequently analysed to provide suggested solutions.
 
Findings: At over 200 million inhabitants, Nigeria is beset with many challenges such as insurgency, deforestation, poverty, food-shortages, limited access to healthcare and so on. Fittingly, there have been some social innovations that have tried to address some of the aforementioned issues with varying levels of success. However, so far, such initiatives have not delivered change on a large scale.  Although there is evidence that there are SI activities in Nigeria, a recurring theme through the literature is the fact that it is difficult to measure the impact of social innovations and there are very limited attempts at documenting and monitoring the outcomes.
 
Research, practical & social implications: This research indicates the need for collaboration, knowledge sharing, in order to contribute effectively to the development and deployment of Social Innovations in Nigeria. Awareness is also a challenge that was raised and is an opportunity for further development.
 
Originality/Value: It is imperative to ensure that social innovations are sustainable particularly where they are direly needed. The sustainability of such innovations is doubtlessly important to ensure that the aim of establishing such initiatives is not thwarted. There is limited academic coverage of social innovations and their impact in developing countries and it is hoped that the various bodies involved in social innovations in such areas will recognise the need for collaboration, knowledge sharing and development of expertise for sustainable social innovation.

Authors: Moosa Riyad , Marx Ben
Published: July 2023

Purpose: The purpose of this study is to investigate the selection criteria of customers in South Africa and to examine these criteria with respect to gender.
 
Theoretical framework: This study is conducted taking into an account an Islamic worldview that is guided by Sharia (Islamic law).
 
Design/Methodology/Approach: A quantitative approach to data analysis was used to meet the purpose of the study. The location of the study is South Africa. The population of interest were customers at Islamic banks who identified as being Muslim. An online survey was used to collect data based non-probability sampling techniques. The final sample used for data analysis consisted of 163 valid responses from Muslims throughout South Africa. Data was analyzed based on mean analysis and an independent sample t-test.
 
Findings:  The results indicate that “religious reasons only”, “Islamic reputation and image” the “economic and financial reputation” and having an “involvement in the community” are the selection criteria considered to be most important by both males and females. The criteria least considered by respondents when selecting an Islamic bank relates to “wide range of facilities offered”, “friend use this type of bank” and “higher rates of return offered”. The results also suggest that there are no significant differences in the selection criteria of customers  based on gender  when choosing an Islamic bank.
 
Research, Practical & Social implications: These results can be used by management of Islamic banks in South Africa in designing policies and launching campaigns to attract new customers and retain existing customers.
 
Originality/Value: This is the first study to consider the role of gender as it relates to the selection criteria of customers at Islamic banks in South Africa.

Mathematical Problems in the Case of a Curriculum: Analysis based on Context and Contextualization
Authors: Chavarría-Arroyo Gilberto , Albanese Veronica
Published: July 2023

The objective of this study is to analyze the context and contextualization of problems from the case of the Costa Rican curriculum developed in the 2012 reform. The mixed methodology consists of a qualitative content analysis and a subsequent quantitative account. A system of categories is built from a literature review leading to the study of types of context and types of contextualization. The 59.5% out of the total of 141 problems has a scientific/mathematics context, with contextualization of the active type in only a few of them. Moreover, contexts of the rural and indigenous types are absent. We conclude therefore that some disconnections exist between the theoretical curricular basis and the problems exemplified. Finally, we propose the further discussion of our categories as indicators for the design of mathematical problems with contextualization of the active and significant types.

E-Lychnophoric acid 1, its derivative ester 2 and alcohol 3 killed 100% of trypomastigoteblood forms of Trypanosoma cruzi at the concentrations of 13.86, 5.68, and 6.48 μg/mL, respectively.Conformational distribution calculations (AM1) of 1, 2 and 3 gave minimum energies for the conformersa, b, c, and d, which differ from each other only in the cyclononene ring geometry. Calculations (DFT/BLYP/6-31G*) of geometry optimization and chemical properties were performed for conformers of 1, 2,and 3. The theoretical results were numerically compared to the trypanocidal activity. Calculated valuesof atomic charge, orbital population, and vibrational frequencies showed that the C-4–C-5 π-endocyclicbond does not affect the trypanocidal activity of the studied compounds. Nevertheless, the structure ofthe group at C-4 strongly influences the activity. However, the theoretical results indicated that the intra-ring (C-1 and C-9) and π-exocycle (C-8 and C-14) carbons of caryophyllene-type structures promotethe trypanocidal activity of these compounds.

The reverse current recovery time is an important parameter of diodes, fast rectifiers and transistors which determined their high-frequency properties and area of application. Defects in the structure may sufficiency reduce the cutoff frequency and lead to overheating. The reverse recovery of the low currents in the α- and β-Ga2O3 Schottky diodes was measured and analyzed in this study. The reverse recovery time in the β-Ga2O3-based Schottky diode is limited mainly by the relaxation of the RC-circuit formed by the equivalent diode circuit and can be very low (20 nsec in this case). Irradiation can introduce some defects in the structure, which may act as deep levels and prolong the relaxation. We have demonstrated experimentally that increasing serial resistance of the circuit lead to an increase in the reverse recovery time. But we can point an additional part of relaxation that can be attributed to the emission from deep levels in the forbidden gap of the semiconductor. It is shown that prolongation increases with the reverse recovery time but saturates. In the α-Ga2O3-based structures the reverse recovery time measured after proton irradiation was 6 μsec, twice as high than it can be expected from RC-circuit relaxation time. These deep levels can be associated with interstitial oxygen atoms. The results obtained can be used to improve the technology of crystal growth to produce Schottky diodes with a high boundary frequency.
Uncertainty: qualitative and quantitative aspects
Authors: Kolesnikov E. Yu.
Published: July 2023

The analysis the concept of uncertainty, its origin, interpretation in various scientific fields, sources of uncertainty, qualitative and quantitative aspects of this concept, as well as approaches to quantifying uncertainty are presented. Methods of historical and comparative analysis were used in the study. The main conclusion is the necessity of taking into account the presence of uncertainty and quantification of uncertainty of the results of mathematical modeling of objects and phenomena of the surrounding world in the same way as we do when assessing measurement uncertainty of experimental data. In is shown that the interval approach to estimating uncertainty of modeling results currently seems to be the most promising. The concept of uncertainty first proposed at the beginning of the last century refers to epistemic situations involving imperfect or unknown information. This concept had only a qualitative aspect for a long time. In the second half of the twentieth century, almost simultaneously with the development of a risk-based approach in the field of technological security, there was an interest in understanding uncertainty, its origin and typification. We are indebted to metrology for giving uncertainty a quantitative aspect, in which, instead of the measurement error paradigm, a measurement uncertainty paradigm was developed, and approaches (partly controversial) to its quantitative assessment were proposed. Uncertainty is an attribute of any data obtained both experimentally or theoretically (currently, usually by mathematical modeling). In the field of experimental research, specifying the uncertainty interval of the result has long been a scientific standard and routine. The time has come to make it mandatory for the results of theoretical research. To date, three alternative methods of quantitative estimation of uncertainty have been developed: probabilistic, fuzzy and interval methods. Methods for leveling the negative features of its initial «naive» version have been proposed in modern interval analysis. It seems to be the most promising method of quantifying uncertainty of the results of mathematical modeling today.
Examining the “Medicare Effect” on Distant-Stage Cancer Diagnoses by Site, Gender, and Rurality
Authors: Semprini Jason
Published: July 2023

Background: Compared to cancers detected early, distant stage cancers are associated with lower survival, diminished quality of life, and higher costs. Evidence suggests that greater access to comprehensive health insurance (i.e., Medicare) improved early detection. Yet, few studies have evaluated the effect of Medicare coverage across cancers or factors influencing healthcare use.
Methods: This study analyzed 35 years of population-based cancer registry data from the Surveillance Epidemiology and End Results program for eight common cancers: Oral, Digestive, Respiratory, Skin, Genital, Urinary, Endocrine, and Breast. Leveraging the subjective threshold determining Medicare’s eligibility at age 65, Medicare’s effect on the probability of a distant diagnosis was estimated using Robust Non-Parametric Regression Discontinuity models.
Results: Medicare was associated with reduced proportion of distant diagnoses for five common cancers. The proportion of distant cancers declined by 1.7-percentage points for digestive cancers (p < 0.01), 1.6-percentage points for respiratory cancers (p < 0.01), 0.5-percentage points for genital cancers (p < 0.05), 1.4-percentage points for urinary cancers (p < 0.01), and 0.8-percentage points for female breast cancers (p < 0.01). The relative difference from average distant stage rates for these significant estimates range from 3% (Respiratory) to 15% (Genital). Most estimates were consistent across gender, but Medicare was only associated with declined distant-stage diagnoses for patients in urban and metro regions.
Conclusions: This study reaffirms that Medicare coverage is associated with earlier diagnoses for patients in urban and metro regions for digestive, respiratory, genital, urinary, and female breast cancers. These results stress the importance of healthcare insurance, but also reveal the limitations of insurance expansion policies for patients in rural areas and for cancers without standard screening protocols.

Published: July 2023

Sultan III.Murad (s. 1574-1595) ve III.Mehmed (s. 1595-1603) dönemlerinde bâbüssaâde ağası göreviyle içoğlanların yaşadığı ve eğitildiği Enderûn-ı Hümâyûn’u denetleyen ve hasodabaşı olarak padişah ile dış dünya arasındaki tek aracı olan Gazanfer Ağa (ö.1603), 16.yüzyılın ikinci yarısının sonlarında Osmanlı Sarayı’nın en güçlü simalarından biridir. III.Murad döneminde hadım kara ağaların (dârüssaâde ağalarının), hadım ak ağalarla (bâbüssaâde ağalarıyla) eşit duruma gelmesi, Saray’da kara ağa Habeşi Mehmed’e (ö.1590) etkin bir siyasi rol kazandırır. Mehmed Ağa elde ettiği ayrıcalıklı konumla mimari ve kitap sanatı alanında da aktif bir hâmîlik sürdürür. İşte onun ölümünün ardından Gazanfer Ağa, Saray’ın sanatsal faaliyetlerine yön vermeye başlayarak ak ağaların üstünlüğünü geri kazanır. Gazanfer, hazırlanışında rol oynadığı tasvirli elyazmaları, baniliğini üstlendiği mimari eserler, himaye ettiği âlimler ve şairlerle, Osmanlı Saray kültürünün üst düzey üyelerinin, gücünü sanatla yansıtma davranışlarını tekrar eder. Yanına sadrazam Koca Sinan Paşa’nın (ö.1596) desteğini de alarak inşa etmeye niyetli olduğu medresesine 1590’da bir müderris atanmasını sağlayan Gazanfer Ağa, öncelikle medreseye müderris seçimi ve seçilen adaya yaptırılan deneme dersini hikâye eden ve taslak halinde kalsa da tasvirli olmasının planlandığı anlaşılan bir elyazması hazırlatır. Yapımı 1593-1596 yılları arasında tamamlanan ve Nâdirî’nin Dîvân’ında sözlü ve görsel olarak betimlenen Gazanfer Ağa Medresesi, merasim güzergâhı olan Divan Yolu’na yakın ayrıcalıklı konumu ve mimarisi ile göz önündedir. Bu çalışmada Gazanfer Ağa Medresesine müderris tayini, medresenin inşası, eğitim süreci ve bir ak hadım olarak Gazanfer Ağa’nın eğitim hâmîliği, Osmanlı görsel kültürüne yansıyan ipuçları çerçevesinde değerlendirilmiş ve medresenin yapım ve eğitim sürecini etkileyen, şekillendiren şartlar ile ilişki ağları ortaya konmuştur.

Published: July 2023

Objective: This study was conducted to determine the effects of putrescine and salicylic acid applications at different doses on germination, plant growth, quality properties and nutrient contents of lettuce under saline conditions.

Materials and Methods: In the study carried out in climatic chamber conditions, a total of 15 different applications using two different salt levels (100 and 200 mM), two different putrescine doses (0.5 and 1.0 mM) and two different salicylic acid doses (0.5 and 1.0 mM) were investigated. The effects of putrescine and salicylic acid separately and together with salt were examined.

Results: According to the findings obtained from the research, it was detected that salinity negatively affected the germination, plant growth, quality properties and nutrient contents of lettuce. In general, it was determined that putrescine applications under saline conditions increased germination and plant growth parameters and significantly reduced the negative effects of salt stress. Furthermore, it was found that the 1.0 mM Putrescine+200 mM NaCl application, in which salt and putrescine were used together, increased germination rate by 75.57%, plant height by 42.49%, plant fresh weight by 58.89% and number of marketable leaves by 43.20% compared to the 200 mM NaCl application.

Conclusion: It was concluded that 0.5 mM Putrescine+100 mM NaCl, 1.0 mM Putrescine+100 mM NaCl and 1.0 mM Putrescine+200 mM NaCl applications were the most effective applications against salt stress in lettuce among the applications examined in the study, and these applications could be recommended as an alternative application method for lettuce cultivation in areas with salinity problems.

Schools in Indonesia conduct distance learning or e-learning, one of which is in the form of the virtual classroom. It has the potential to improve digital and information literacy among teachers and students, furthermore it could turn the “banking system” learning style to become a more “problem-posing” strategy. However, it seems that virtual classes only use the internet as a support system, not as a learning ecosystem. This paper aims to look at the online learning process carried out by teachers and students in virtual classrooms, through qualitative research with several high school teachers selected by purposive sampling as research subjects. As a result, most informants revealed that virtual classes still referred to offline conventional classrooms with their obstacles such as uniformity, banking system, lack of information literacy, and the internet had not become a learning ecosystem yet.

Hasilnya, sebagian besar informan mengungkapkan bahwa kelas virtual masih mengacu pada kelas konvensional luring dengan berbagai tantangan seperti penyeragaman, banking system, kurangnya literasi informasi, dan internet belum menjadi ekosistem belajar.
