Published: May 2022

Tomato (Solanum lycopersicum L.) yields have continued to plummet in Kenya due to biotic stresses and reliance on low yielding varieties. This study aimed at determining heterosis and combining ability for fruit yield and yield components among tomato genotypes and select F1 hybrids combining high fruit yield and other market demanded traits under Kenyan conditions. Ten parental genotypes and their 45 F1 hybrids were studied using 10×10 half diallel mating design, excluding the reciprocals and the self’s. The experiment was set up in Kiambu and Kirinyaga Counties in Kenya. Out of 45 F1 hybrids evaluated, 89% had reduced (negative heterosis) days to 50% flowering and 11% days to maturity, compared to their better parents. Higher heterosis (-9%) was recorded on days to flowering in AVTO1429 x Cal J VF) and -5% for maturity in Roma VF x AVTO1314. All the F1 hybrids had positive heterosis for number of trusses per plant and fruit yield. F1 hybrid AVTO1429 x AVTO1314 had the highest positive heterosis of 114.39% for fruit weight per plant yield. The results showed high significant difference among the ten genotypes for general and specific combining ability effects (male x female) for all the traits evaluated. There was additive and non-additive gene action for the traits, which are important aspects in developing a tomato breeding programme.

The study examined the awareness level of poultry farmers on biosafety practices on infectious diseases in Kano state, Nigeria. A two-stage sampling procedure was used in selecting 166 respondents through the use of questionnaire. The data were analysed using mean, percentages, and standard deviation. The result showed that the main sources of awareness of biosafety practices were mass media (48.8%), family/friends/neighbours (25.9%) and poultry farmers’ association (PAN) (11.4%).  Awareness of biosafety were in the following component cleaning (low pressure washer ( x̄ =1.602) and hand washing after toileting (x̄ =1.789), disinfection covering feeds in the store (x̄ =1.560), manure management (x̄ =1 .608) and removal of dead carcasses (x̄ =1.530). component. At segregation and traffic control all the subcomponents were known except; banning keeping of birds at home (x̄ =1.114), exclusion of rodents & wild birds (x̄ =1.054) and presence of buffer areas around the farm (x̄=1.000). The Majority of the respondents claimed very low levels of awareness of biosafety practices (81.9%), major constraints to biosafety practices among the clienteles were; complexity of the biosecurity, inadequate capital (93.4%) and high cost of the biosafety practices (83.1%). Awareness level of the respondents should be improved upon through sensitization and provision of more extension services in addition to the mass media effort.

Authors: Akinwale Jonathan Akinsola , Omobuwa Tomipe Sunday
Published: May 2022

The extent at which agricultural extension is rendering support towards ensuring market-oriented cocoa production formed the basis for this study. Multi-stage sampling procedure was used to sample 76 cocoa farmers in Ife-East Local Government Area of Osun State. Radio was the mostly used (92.1%) extension communication channel by the extension agents. The most established linkage was found between farmers and agro-dealers (85.5%). The prominent activities performed by the extension agents toward market-oriented cocoa production were: training on production techniques (x̄ =3.62), establishing linkage with input supplies (x̄ = 3.56) and tailored marketing production (x̄ = 3.53). Meanwhile, provision of sales outlets to sell produce (x̄ = 2.91) was ranked low by the cocoa farmers. There was high level of trust for cooperative leadership (x̄ = 1.86) and extension services (x̄ = 1.81) . There was no significant relationship (r = -0.037) between activities performed by the extension agents and level of trust with other actors. Agricultural extension services should work with relevant governments and non-governmental organizations to create alternative marketing channels to sustain the current efforts at achieving market-oriented cocoa production.

Published: May 2022

The study investigated factors influencing smallholder farmers’ participation in fish farming in Lesotho. Multi-stage sampling procedure was used to select 400 farmers from whom data was collected through a semi-structured questionnaire. Percentage and binary logistic regression were used to analyse the objectives of the study. Results revealed that government support (β=2.662), lack of arable land (β=2.824) and social capital (β=2.387) enhanced participation in fish farming while membership in farmer group/association (β=1.925), path dependency (β=2.007) and culture (β=2.985) had a constraining effect on participation in fish farming in the country. Based on the results, it is concluded that institutional, technical and socioeconomic factors influence participation. In light of these, it is recommended that unobservable and informal institutional factors be taken cognisant of in the design of fish farming development policies and strategies in Lesotho. Furthermore, the formation of fish-based farmer organisations be encouraged, promoted and supported in the country.

Published: May 2022

In addition to the evolution of green and nano energy, sequestration of CO2 is also an evolving method to control the global CO2 footprint and greenhouse effect. Carbon Capture and Sequestration (CCS) is an established technique to capture carbon from anthropogenic sources, such as power and chemical plants, and then inject the same in subsurface rock micropores, to permanently store the CO2. Besides its environmental credentials, CCS also offers economic opportunities in Gas Enhanced Oil Recovery and Methane displacement in coalbed reservoirs. CCS process incorporates various geological, geometrical and engineering understandings of porous media and fluid dynamics. Previous investigators have identified low permeability rock as a better site for CCS. However, little is known of the propagation and effectiveness of CCS in reservoirs that have multiple layers of sedimentation, vis-à-vis well topology and density, flow direction, storage site, and power optimisation. In reality, these layers altogether form a structural rhythm and gradient. In this study, we investigated the structural rhythms and gradients that optimise CCS by using two objective functions (Darcy and interstitial flowrates) and 15 structural criteria (such as pore size, porosity, tortuosity, and aspect ratio). An experimental method has been applied. Five analogous reservoir porous core samples with varying structural parameters have been tested. The results indicate that CCS optimisation is responsive to structural parameters. The rhythm analysis from this study suggests that the CCS gas flow requires a compound rhythm that has a positive porosity and negative pore gradients. That is, the CCS injection wells should be placed in the reservoir area with relatively low porosity (3%) and large pore size (6000nm), while the storage site should be at a relatively high porosity (20%) and smaller pore size (200nm). This study can be directly applied to CCS practice, such that, given a layered reservoir, engineers can predict the well placement or topology that would optimize some of the essential performance objectives of CCS.
Medical Image Denoising Techniques: A Review
Authors: Patil Rajesh , Bhosale Surendra
Published: May 2022

Medical imaging means the methods and procedures used for creating pictures of various parts of the human body for numerous clinical objectives. These images are constantly gets dirtied by noise during picture acquisition and transmission, resulting in low quality images. Noise is the unwanted signal which corrupts the important and desirable information. The noises can be categorized into different types based on their nature and origin. e.g. Gaussian, the impulsive and speckle noise etc. The removal of noise is very necessary for proper analysis and diagnosis. Filtering noise helps to recreate a high-quality image in digital image processing for further image processing such as segmentation of images, identification, recognition and monitoring, etc. There are various approaches to denoise medical images based on transform approach, machine learning, filtering method and statistical method. These techniques or approaches is subject to noise type exist in the image. To evaluate the denoising performance, parameters like SNR, PSNR etc. are used. This paper takes a review of current denoising techniques.

The challenge of unimpressive performance in science subjects is worldwide as revealed by various international research investigation. The increasing rate of low academic achievement and failures in science subjects in schools may significantly impact both individual students whose target was to proceed with tertiary education and seek a lifetime opportunity. However, all of these aims may be affected by the unimpressive performance of students in science subjects. The aim of this study was to describe the experiences of science teachers who encountered problems and challenges in teaching non–science subjects. The study utilized the qualitative phenomenological design with two data gathering techniques, the in-depth interview and focus group discussion. There were 14 participants in this study who were science teachers from secondary schools in Montevista district, Davao de Oro Division, Mindanao, Philippines. Data triangulation was addressed through generating data from various sources to gain a fuller perspective of the study. There (3) essential themes were generated on the experiences of teachers from teaching Non–science subjects. As to the result, the study further recommends on the revisitation on the hiring policy, plans and programs for teachers particularly the need for teacher’s alignment of subject as to what teachers’ specialization or subject field of expertise.
Ethical Considerations and Reimaging State Corrections: Education and Work Partnerships for Offenders Return to Home and Community
Authors: Garth-James Kimberley
Published: May 2022

This paper describes a mixed method study of 16,000 postings on Twitter, YouTube, and Reddit related to corrections (prison) reforms and a survey of 140 participants in this discourse who expressed a strong interest in reform focused on ethics, education, and work partnerships. The theoretical modeling of “what works,” arguably, can facilitate the reform of individual offenders as well as rehabilitation and recidivism-reduction programs. The methodology combined a review of empirical research for years 1990 to 2018 with social media posts by members of the public and a narrative survey of public professionals. The results indicated that work, education, and morality all have significant roles to play in reimagining prison systems so that simply warehousing prisoners and “nothing works” thinking become ideas of the past. The COVID-19 pandemic and social justice concerns about prisoners have created conditions conducive to social media activism aimed at making prisons more humane. Accordingly, corrections professionals, policymakers, and students need solid research on these issues to assess the outcomes of corrections policies for communities.
The Making of a 21st Century English Language Teacher during the Pandemic
Authors: Chehimi Ghada , Alameddine Mira M.
Published: May 2022

English language has become a cosmopolitan language. It is the lingua franca of the 21st century. This fact has turned learning the language to a must since it is the international language of communication. As teachers of English for more than 20 years, we have come to realize that to be successful in class, we need to learn and use English as a tool that helps us access information from other cultures and be able to transfer this knowledge and skill to our learners. We also need to provide our learners with enough exposure to English as used in context. However, this is not enough to turn our learners into 21st century citizens of the world. We need to help them become critical thinkers. This has become even harder with the move to online learning due to COVID 19 pandemic.  This paper aims at exploring the perceptions of English language instructors in four local Lebanese universities regarding 21st-century critical thinking skills and the instructors' abilities to promote such skills in their classes. Twenty-seven teachers filled a questionnaire, and five participants were interviewed. Descriptive data were analyzed. The data revealed the perceptions and practices of these instructors. The study concludes with recommendations.
Gender Representations in the Greek Primary School Language Textbooks: Synthesizing Content with Critical Discourse Analysis
Authors: Alexopoulos Christos , Stamou Anastasia G. , Papadopoulou Penelope
Published: May 2022

School textbooks are media of communicating a large amount of knowledge and teachers rely their teaching practices and schedule their instructions upon them. Except for knowledge on school subjects, textbooks also promote various ideological messages, including gender representations. This study explores gender representations in the Greek primary school language textbook addressed to the first grade, which is currently being taught. For this purpose, Content Analysis and Critical Discourse Analysis are employed in synergy, as Content Analysis on its own is insufficient to fully explore gender representations and the ideologies of school textbook discourse. The results showed clearly that traditional gender representations are reproduced in the particular textbook, by presenting men dominating in the public sphere, and leading women’s lives and their families.

This article aims to present youth and adult education in the prison context, evaluating its effectiveness in resocialization from the observation of the pedagogical-administrative management of an elementary education school located in a medium-security prison in the city of João Pessoa, state of Paraiba. The justification for this study is the belief that education opens the doors of knowledge, in which bridges are built for the critical development of human beings. The following question guided this research: What are the main challenges, limits, and possibilities of the administrative-pedagogical management of a school in a prison context for Youth and Adult Education deprived of freedom? This qualitative study relied on a five-question questionnaire addressed to its director. School in prison should be a place of freedom of thought and a place where the inmate would feel safe. The education role in the prison system is to rebuild the identity lost by the person deprived of freedom and to rescue their citizenship, thus making the prison environment less painful and a rightful place for those who are convicted.

Authors: Chen Junlin
Published: May 2022

Plagiarism is prevalent all over the world, especially in higher education. This quantitative-descriptive study investigated the reasons and gender differences for plagiarism among undergraduate students at Wenzhou-Kean University (WKU). To collect quantitative data, the random sample of 102 undergraduates at WKU answered questions about plagiarism in the online questionnaire. The results revealed that the development of technology and the Internet is the main reason for plagiarism. Surprisingly, the study found that students are confident with their citation skills. The participants reported that using additional materials to help with their online testing is easy during the COVID-19 pandemic. The COVID-19 pandemic has become another significant reason for plagiarism. In terms of gender differences, the results showed no significant difference in attitudes and behaviors toward plagiarism among WKU undergraduate students by gender. The study advises educational institutions like WKU should use both traditional solutions (e.g., failing the plagiarized assignment, giving suspension to student) and new solutions (e.g., using plagiarism tracking system) to deal with plagiarism.

The social interactions that take place in science museums, whether between family members or with mediators, are recognized as essential to visitors’ experience. However, there is still little empirical research in the Brazilian context on how families interact and converse on visits to science museums – and even less on the role of the mediator in the museum experience. In this exploratory study, the authors analyze the social interactions of families in an interactive exhibition on biodiversity: “Forest of the Senses”, at the Museum Science and Life (Brazil), characterized by having one of the lowest human well-being indicators in the country. In particular, the authors analyzed the ways in which the presence of human mediation influenced the experience of family visits to the exhibit. Video and audio of ten low-income families' visits were recorded and analyzed using a protocol based on social interactions that take place in museums. Results show that human mediation did not influence the amount or types of visitor-exhibit interactions or the amount of time spent at the exhibit, but increased the amount of conversation time among the groups, including the amount of time discussing science content, thus providing insights into mediator training and qualification.

Published: May 2022

This study uses the self-determination theory to explore how personal characteristics, motivation and learning environment influence students’ attitudes toward the learning of mathematics. The study adopted a sequential mixed methods design, with 360 students from 24 schools, constituting the sample for the study. The results revealed that in general, students have positive attitudes toward the learning of mathematics, and this could be attributed to the utilitarian motive of mathematics and its importance in daily life. Pearson Moment Correlation and independent T-test analysis were used to ascertain if there is any relationship between students' attitudes toward mathematics and their academic performance and the relationship between performance and school location. Also, the results from the interviews revealed a direct relationship between personal characteristics, motivation, learning environment and students' attitudes toward mathematics, as motivated students, and experience positive learning environments performed better. Based on the findings, we recommend that teachers and educational authorities ought to be innovative in using creative approaches that will motivate students in developing a more positive attitude toward the learning of mathematics as this is very crucial in our quest for improving students' performance in mathematics.

Abriendo la caja negra de la decisión sancionadora: Un estudio de las variables involucradas en la imposición de una separación del grupo
Authors: Ruiz Cabello Úrsula
Published: May 2022

La literatura previa sobre la toma de decisiones sancionadoras en instituciones penitenciarias ha puesto de relieve la existencia de factores legales y extralegales que afectan a la elección de la respuesta disciplinaria. Estos factores parecen particularmente relevantes cuando se trata de una sanción de aislamiento. La presente investigación pretende estudiar qué factores influyen en la imposición de una sanción de separación del grupo por días y en su duración en centros de internamiento para menores infractores. Para ello se llevan a cabo análisis inferenciales sobre una muestra de jóvenes sancionados disciplinariamente en un centro de internamiento catalán. Los resultados muestran que tanto la elección de la separación de grupo como su duración atienden principalmente a factores legales, aunque también se observa la influencia de factores extralegales, como por ejemplo que el hecho de ser hombre aumenta las probabilidades de ser aislado.
Mediações algorítmicas e espiral do silêncio

Assessment of the impact of clear-cutting on groundwater regime in swampy habitats
Authors: Stasik Rafał , Sojka Mariusz , Korytowski Mariusz
Published: May 2022

The aim of the study was evaluation of clear-cutting effect on water regime in a tree harvesting area. The results were made based on the study carried out in the Rakowski Ditch catchment, in Wielkopolska lowland in Poland. It was found that a more useful method to establish the effects of clear-cutting is to compare the groundwater level (GWL) in the post-clear-cutting area with that in a control area than to analyse the GWL changes in the same area before and after the clear-cutting. Regression analysis is a particularly useful tool in groundwater regime analyses. The results obtained in this study indicated that the groundwater regime changes in the post-clear-cutting area that were manifested as an increase in the mean GWL. The major changes in the groundwater regime after clear-cutting were observed in the minimum levels, while the lowest changes took place in the maximum GWL. The variation in GWL was higher in the period after clear-cutting than in the period before it. The analysis of linear regression of GWL in the well located in the clear-cutting area and that in the control area confirmed the change in the groundwater regime in the post-clear-cutting area. Stronger relations in the period before clear-cutting were observed.

Published: May 2022

In 1996 and 1998, Professor A. Korczyk created a half-sib plantation of the European silver fir (Abies alba Mill.) in the Polish part of the Białowieża Forest (Hajnówka Forest District, sub-district Wilczy Jar, subcompartments 416Ag and 416Сf). The planting was carried out in furrows at a spacing of 1.3 × 1 m in three plots of 0.22 ha each in an area of fresh broadleaved forest. To grow the seedlings, seeds from the “Tisovik” tract (in the Belarusian part of the Białowieża Forest) were used. According to some researchers, the Abies alba in this tract has a natural origin and is a relic of the Białowieża Forest. Given this circumstance, and in connection with the mass drying-out of the Norway spruce, Picea abies (L.) Karst., there is a practical interest in studying the growth of fir establishment in this territory. The results of our studies (2018) indicated the very intensive growth of this species in 22-year-old cultures (sub-compartment 416Ag, plot 1, 10 half-sib families). The trees showed no signs of disease or insect damage, their crowns were conical in shape and the shoots were densely covered with needles. The good state of the forest planting can be considered as evidence of soil and hydrological conditions suitable for growth and meeting the ecological and biological requirements of A. alba, as well as confirmation of its autochthonous nature. Key words: Abies alba, reintroduction, half-sib plantation, Białowieża Forest

The impact of COVID-19 has affected not only private citizens, but also arts entrepreneurship professionals and their respective business models. To explore both the problems experienced by professional music entrepreneurs and their solutions for navigating company survivability, growth and impact, a multiple-case qualitative research study using intensity sampling and grounded theory was conducted to uncover how professional music entrepreneurs (N = 5) succeeded in not only surviving the pandemic’s effects on their personal businesses, but also in augmenting their companies’ finances, resources and impact within the constructs of a post-COVID multimodal creative economy. The results present various themes and suggestions for implementation within music (and arts) entrepreneurship practice and education.

Bullying behaviors in the workplace are marked by repeated events of intimidation that create a pattern of humiliation and fear in the victim. School staff in K-12 schools are not immune to bullying behavior by other adults in the organization. Educators experience personal and professional repercussions when confronted with bullying experiences by other educators or educational administrators. This qualitative study demonstrates the breadth of the issue and emphasizes the roles of a school psychologist, school social worker, and human resource personnel in the wake of the potential ethical challenges that present when a staff member reports they are being bullied. Additionally, other involvement remedies include responsible contributions toward incorporation of policies and mental health innovations that will address the adult population in a school or district.

Introducción: el aislamiento obligatorio impuso cambios en la vida y en los hábitos de las personas con diabetes mellitus (DM). Es importante conocer la situación actual para diseñar la intervención nutricional y generar información útil para el equipo de atención.Objetivos: conocer la percepción acerca del consumo de alimentos y la situación médico-nutricional de personas con DM durante el aislamiento por COVID-19.Materiales y métodos: estudio observacional. Se aplicó cuestionario autoadministrado. Muestra no probabilística. Las variables se categorizaron y analizaron según los objetivos específicos.Resultados: se encuestaron 1.128 pacientes. El 42,3% padecía DM1; 35,6% tenía más de 10 años con DM. El 25,7% nunca asistió a un nutricionista por su DM y 56% contaba con un plan alimentario por nutricionista. En cuanto a la derivación al nutricionista por DM, el 68,3% fue derivado y asistió. Durante la pandemia, el 66,7% de los participantes no acudió a la consulta nutricional. Un 67,3% de pacientes DM1 aplicó conteo de hidratos de carbono (HC). Por otro lado, el 39% percibió aumento de peso y un 20,6% déficit en el control de la glucemia. El 82% refirió consumir comidas caseras, 24% delivery, 27% comidas rápidas, 28% alcohol, 20% gaseosas, 19% golosinas, 74% verduras y 71% frutas. En cuanto a los problemas percibidos, fueron más frecuentes el estrés (45,9%), el sedentarismo (42,7%) y las comidas poco saludables (24,9%).Conclusiones: los resultados obtenidos podrían mejorar las estrategias de tratamiento y acompañamiento a nuestros pacientes. Resulta necesario mejorar la derivación y seguimiento, además de trabajar sobre la frecuencia de la actividad física y los motivos de ingesta.

Tidur merupakan perkara penting untuk pertumbuhan kanak-kanak. Ia bukan saya penting untuk tumbuh besaran malah emosi dan kognitif turut dipengaruhi oleh tidur. Namun sejak penularan pandemik Covid-19 ia telah memberi kesan terhadap rutin tidur kanak-kanak. Pusingan tidur mereka terjejas. Oleh itu, kajian ini dilakukan untuk melihat sejauh mana tahap kualiti tidur murid sekolah rendah ketika pandemik Covid-19 berdasarkan jantina, kaum dan lokasi sekolah serta hubungannya dengan aktiviti fizikal. Instrumen yang digunakan adalah Pittsburgh Sleep Quality Index (PSQI) yang mengandungi tujuh komponen. Nilai alpha cornbach instrumen ini adalah 0.90 menunjukkan tahap kebolehpercayaan yang tinggi. Untuk menentukan kualiti tidur sama ada baik atau buruk kesemua skor komponen dijumlahkan dan jika skor akhir ≤5 kualiti tidur adalah baik, jika skor >5 kualiti tidur buruk. Dapatan kajian mendapati 52.4% daripada 124 orang responden mempunyai kualiti tidur yang buruk. Manakala dapatan berdasarkan kaum, jantina dan lokasi sekolah didapati tidak terdapat perbezaan yang signifikan bagi ketiga-tiga pemboleh ubah tersebut. Begitu juga dengan hubungannya dengan aktiviti fizikal tidak terdapat hubungan yang signifikan antara kualiti tidur dengan aktiviti fizikal. Kajian ini dijalankan menggunakan kaedah persampelan bertujuan bagi pemilihan sekolah dan persampelan rawak mudah bagi pemilihan responden.

Makarna ve Erişte Çeşitlerinde Glioksal ve Metilglioksal biyoerişilebilirliklerinin İn vitro Sindirim Metodu ile Belirlenmesi

Besinlerin işlenmesi sırasında oluşan İleri Glikasyon Son Ürünlerin [Advanced Glycation End Products (AGEs)] heterojenliği, fizyolojik olarak oluşan AGE’lerden daha fazladır ve diyet AGE'lerinin çeşitli olması etkilerini karmaşıklaştırmaktadır. Diyetle alınan AGE’lerin kronik hastalık riskini arttırdığı vurgulanmaktadır. Mevcut çalışmada toplum tarafından sık tüketilen besinlerden olan makarna ve eriştelerde başlangıç ve in vitro sindirim metodu sonrasındaki glioksal ve metilglioksal düzeyleri ve biyoerişilebilirlikleri araştırılmıştır. Makarna ve erişte örneklerindeki başlangıç GO ve MGO değerleri sırasıyla 0,112-2,607 µg/100 g ve 1,641-11,675 µg/100 g olarak saptanmıştır. İn vitro sindirim işlemi sonrasında tüm örneklerdeki GO ve MGO içeriklerinde artış saptanmıştır. Sindirim sonrası GO ve MGO içerikleri sırasıyla 0,847 ile 6,624 µg /100 g ve 5,563 ile 24,932 µg /100 g olarak belirlenmiştir. GO için en yüksek biyoerişilebilirlik %1098 ile yumurtalı eriştede görülürken, MGO’da ise %519 ile standart makarnada görülmüştür. Sindirim sürecinde açığa çıkan serbest şeker miktarının AGE öncülerinin artışına katkıda bulunduğu düşünülmüştür. Bununla birlikte sindirim sonrasında her ne kadar ürünlerin GO ve MGO biyoerişilebilirlikleri artmış olsa da 100 gram üründeki miktarları incelendiğinde ürünlerin AGE öncüleri içeriğinin düşük olduğu söylenebilir. İnsan beslenmesi genel olarak karışık bir kompozisyona sahip olduğundan diyette yer alan tüm besinlerin AGE içerikleri önem arz etmektedir. Bu nedenle ülkemizde sık tüketilen ürünlerin AGE içeriklerinin belirlenmesi ve içeriklerin azaltılabilmesine yönelik tekniklerin geliştirilmesinin halk sağlığı açısından önemli olduğu düşünülmüştür
