Kiloparsec-scale Radio Structure in z ∼ 0.25 Radio-quiet QSOs
Authors: McCaffrey Trevor V , Kimball Amy E , Momjian Emmanuel , Richards Gordon T
Published: September 2022

We present analysis of a homogeneous, optically selected, volume-limited (0.2 < z < 0.3) sample of 128 radio-quiet quasi-stellar objects (QSOs) recently observed at 6 GHz with the Very Large Array (VLA) in A configuration (∼0.″33 resolution). We compare these new results to earlier (2010–2011) 6 GHz observations with the VLA in C configuration (∼3.″5). While all of these radio-quiet QSOs (RQQs) were unresolved on a 3.″5 scale (∼14 kpc at z = 0.25), we resolve notable complex subgalactic structures in about half of the RQQs at 0.″33 resolution (∼1.3 kpc at z = 0.25). By comparison of flux density measurements between the two sets of observations, we demonstrate that significant sub-galactic-scale radio structure is present in at least 70% of the RQQ population and that the central component accounts for an average of ≈65% of the total detected radio power. One RQQ, J0935+4819, shows striking symmetric, double-lobed morphology and appears to be the first identified example of a radio-quiet QSO with FR II type morphology on ∼arcsec scale (projected size of ≳6 kpc). In addition to revealing RQQ subgalactic morphology, we employ counterparts from legacy (FIRST at 1.4 GHz) and recent (VLA Sky Survey at 3 GHz) VLA surveys to investigate radio spectral indices and potential variability over decades-long timescales for a subset of the RQQs and for the cores of radio-intermediate and radio-loud sources in the parent sample of 178 QSOs. These results support the growing notion that the RQQ population is not a monolithic phenomenon but instead consists of a mixture of mainly starburst-powered and jet-powered galaxies.
Incivilités numériques
Authors: Sitte De Longueval Oriane
Published: September 2022

Les incivilités et les agressions des clients font partie du quotidien des employés de service. En théorie, les deux phénomènes sont clairement distingués : l’incivilité déroge à l’ordre établi sans réelle intention de nuire, tandis que l’agression déroge à ce même ordre dans l’intention de nuire. Mais en pratique, les deux termes sont souvent associés ou confondus. Ce chapitre rend compte de cette imbrication, à partir d’une enquête qualitative menée auprès des employés de service d’une entreprise ferroviaire. Il montre que si ces opérateurs vivent des situations univoques d’agressions et d’incivilités, ils font aussi face à des situations plus ambiguës – des agressions involontaires et des incivilités respectueuses – et plus ambivalentes – des incivilités agressives et des agressions civiles.
Elle ne devait pas être reine
Authors: Roche Marc
Published: September 2022

Élisabeth II est la femme la plus célèbre du monde. Devenue reine par accident en 1952, après la disparition prématurée de son père, elle a réussi à surmonter toutes les crises, politiques, diplomatiques et familiales, pour asseoir l’une des institutions les plus anachroniques au monde : la monarchie britannique. Au départ pourtant, rien ne prédestinait cette princesse royale, timide, au maintien modeste et à l’éducation sommaire, montée sur le trône sans aucune préparation, à atteindre un tel prestige.
Empirisme, constructivisme et grande théorie dans les approches sociologiques du droit : le cas de la réglementation privée transnationale
Authors: Kampourakis Ioannis
Published: September 2022

Résumé : Dans cet article, je discute du contraste épistémologique entre les études socio-juridiques empiriques et la « grande théorie » des approches systémiques du droit en me concentrant sur la façon dont elles abordent la réglementation privée transnationale. Les études socio-juridiques empiriques partagent un engagement épistémique envers une réalité sociale objective et connaissable, et elles ont tendance à considérer les acteurs humains comme les moteurs de l’histoire. Ainsi, elles se concentrent sur la dynamique interrelationnelle au sein des chaînes de valeur mondiales (CVM), à la recherche de « ce qui fonctionne » dans la réglementation privée transnationale. Au contraire, la jurisprudence sociologique orientée vers la théorie des systèmes considère la réalité sociale comme construite et fragmentée en épistèmes de différents systèmes sociaux. Les chaînes de valeur mondiales sont comprises comme des ordres normatifs autoréférentiels, dans lesquels la question de l’agence et des acteurs humains est secondaire l’accent est mis sur les communications et les forces anonymes d’ordonnancement. En essayant d’examiner les possibilités de synthèse, je demande à quel point nous pouvons et devons penser « grand » en matière de droit et de société. Je tente ainsi d’esquisser une approche qui part de la matérialité des structures sociales pour étudier les processus au-delà de l’agence individuelle et découvrir des éléments de reconstruction normative du domaine particulier de l’activité sociale.
La dimension systémique des pratiques commerciales déloyales dans les chaînes d’approvisionnement alimentaire : un point de vue sur la directive 2019/633/UE et sa transposition par les États membres
Authors: Cafaggi Fabrizio , Iamiceli Paola
Published: September 2022

Résumé  : L’article soutient l’idée que les pratiques commerciales déloyales dans les chaînes d’approvisionnement présentent des caractéristiques spécifiques ; en conséquence, elles nécessitent des règles et des recours spécifiques. Il convient d’établir une distinction entre les pratiques commerciales déloyales isolées, dont les effets restent essentiellement dans le cadre de la relation contractuelle bilatérale, et les pratiques commerciales déloyales systémiques, dont les effets se propagent directement ou indirectement le long de la chaîne. Ces dernières entraînent des conséquences beaucoup plus graves, tant en termes de distribution que d’exclusion. En examinant la directive 2019/633/UE sur les pratiques commerciales déloyales (PCD) dans les chaînes agroalimentaires et sa transposition par certains États membres, les auteurs développent un cadre conceptuel qui pourrait être utile pour compléter la réglementation existante et à venir aux niveaux européen et national par des règles reflétant la dimension de la chaîne d’approvisionnement des PCD. Plus particulièrement, les auteurs suggèrent que les effets systémiques de distribution et d’exclusion devraient être pris en compte dans a) la définition de la pratique interdite et b) le choix et le contenu des sanctions et des recours. Bien que jusqu’à présent ces distinctions aient été rarement prises en compte par les États membres dans le cadre de la transposition, elles pourraient jouer un rôle important dans les tribunaux lorsque les responsabilités, les sanctions et les recours doivent être déterminés.
L’œil sociologique. Transmettre l’analyse sociologique par le documentaire photographique. Entretien avec Brice Le Gall
Authors: Le Gall Brice , Pouly Marie-Pierre
Published: September 2022

Cet échange évoque les conditions de possibilité de la transmission sociologique en proposant un retour réflexif sur l’engagement sociologique avec et auprès des Gilets jaunes de trois ronds-points de l’Oise, appareil photo à l’appui. Il aborde d’abord le déroulement de cet engagement et la forme prise par les relations d’enquête qui ont permis la production d’un savoir sociologique différent de celui qui avait cours, concernant cette mobilisation, dans les univers médiatique et politique. Il revient ensuite sur l’élaboration d’un livre de photographie sociologique qui tente de mettre une analyse sociologique à la disposition de celles et ceux qui ont d’ordinaire peu de chance d’y avoir accès et souligne, à ce titre, l’intérêt qu’il y a à mettre en lumière le savoir-faire souvent invisibilisé des graphistes. Au-delà de la circulation des photographies et du livre chez les Gilets jaunes étudiés, l’échange décortique, pour finir, la réception de ce que l’on peut appeler la photographie sociologique dans les univers académique, journalistique et photographique.
Qui représente la « diversité » ? Les conditions sociales et professionnelles de l’accès à une aide publique dans le secteur audiovisuel français
Authors: Mayenga Evélia
Published: September 2022

En France, les financements publics occupent une place particulière dans les circuits de production et de consécration du cinéma et de la télévision. Offrant des ressources financières et une légitimité à des œuvres jugées comme étant de « qualité », ces aides constituent un observatoire propice pour identifier les rapports sociaux intriqués, de genre, de race, de classe, qui organisent l’accès à la création audiovisuelle. En prenant pour objet la commission « Images de la diversité », un dispositif de financement singulier destiné à lutter contre les discriminations dans le domaine audiovisuel, cet article propose d’étudier les modalités de ce soutien de l’État à un secteur culturel. Créée en 2007 pour aider des œuvres contribuant à « représenter la diversité », cette commission a mis en œuvre des critères d’attribution entre artistique et politique, et à la jonction de rapports de race, de classe, d’âge et de migration. En analysant un corpus de 1 318 œuvres, récits et sociétés de production aidés, cet article cherche à identifier les conditions sociales et professionnelles de ce soutien à la « diversité », et de l’accès à la production et à la légitimité dans le secteur audiovisuel français.
Avant-propos

Published: September 2022

La science diffusée dans les grandes écoles, défendue par les académies et prônée par les maîtres du moment a eu aussi ses contestataires et ses « refusés ». Comme il est d'usage, c'est sur la place publique, par la voix des journaux, que beaucoup de rebelles ont tenté de répandre leurs idées fécondes et ont livré combat contre les grands. C'est en se faisant vulgarisateurs qu'ils ont fait leur révolution. C'est à ces « refusés » que ce livre est consacré. Faire l'histoire des conflits entre l'ordre figé des grands corps et des institutions savantes, et la contestation, politique ou seulement scientifique, de savants souvent méconnus ou rejetés dans l'ombre des pontifes de l'époque, c'est refuser un positivisme, déficient mais persistant, qui n'admet que la science reconnue et renvoie au rôle de seconds couteaux tous ceux dont l'imagination féconde et l'originalité risquent de troubler l'ordre établi.
Jules Janssen : un refusé à l'ombre du soleil
Authors: Le Gars Stéphane
Published: September 2022

Né dans une famille bourgeoise où l’art occupe une large place, Jules Janssen est un autodidacte des sciences et doit travailler dans la banque puis comme précepteur tout en collationnant les grades universitaires. Très vite, sa curiosité et ses aptitudes expérimentales sont concentrées sur le Soleil. Doté d’appuis politiques et membre de multiples sociétés savantes, il peut satisfaire son goût des voyages scientifiques et obtenir la création de deux observatoires dédiés à l’astrophysique dont il jette les bases en France. À l’observatoire de Meudon, cet homme des chemins de traverse favorise la carrière de ceux qui, comme lui, ne sont pas sortis du sérail. Son parcours nomade est aussi marqué par quelques affrontements avec des savants de l’establishment, comme Cornu et Deslandres. Leur formation à Polytechnique assure ces derniers d’une carrière sans accroc et leur permet d’imposer leurs méthodes souvent éloignées des passerelles inventives que Janssen bâtit entre les disciplines.
Achille le bel (1847-1930), un chimiste innovant tenu à l’écart par ses pairs
Authors: Emptoz Gérard
Published: September 2022

L’histoire de la chimie a retenu que deux chimistes, le Français Achille Le Bel, et le Hollandais Jacobus Van't Hoff (1852-1911) ont été les co-fondateurs de la stéréochimie moderne pour avoir proposé séparément et sans aucune concertation, la théorie de la dissymétrie moléculaire en 1874. Quatorze années après sa découverte, Le Bel décidait de rechercher la reconnaissance de ses collègues français en présentant sa candidature à l’Académie des sciences, et obtenir ainsi une notoriété méritée. De son côté, Van’t Hoff recevait les fruits de sa découverte en obtenant des chaires de professeur dans de grandes universités à Amsterdam, puis à Charlottenburg, et le premier Prix Nobel de chimie en 1901. Pour Le Bel, après huit candidatures malheureuses à l’Institut, le qualificatif de « refusé » peut s’appliquer. Le poids des réseaux en place dans les institutions scientifiques de l’époque et aussi des affrontements au sein des chimistes français ont contribué à ces échecs. En étant finalement élu en 1929, Le Bel aura fait les frais des tensions au sein du monde scientifique national.
Hatfield and the North (1974) : une synthèse en équilibre
Authors: Costa Jacopo , Lalitte Philippe , Michel Pierre
Published: September 2022

Le groupe Hatfield and the North figure parmi les plus représentatifs de la Scène de Canterbury : ses deux albums en constituent une production importante. Le premier album de 1974, simplement intitulé Hatfield and the North, est abordé ici essentiellement et selon plusieurs approches successives : contextualisation, forme des morceaux, analyse de l’enchaînement des morceaux pour chaque face du vinyle sur la base de la théorie des attentes musicales, les apports des différents musiciens et leurs spécificités dans le jeu instrumental, la pratique des métriques complexes dans « Shaving is boring » et « Lobster in Cleavage Probe », les différentes approches stylistiques des quatre membres du groupe et les interactions entre leurs conceptions musicales propres. Les contributions de trois musicologues convergent en une analyse détaillée et diversifiée des caractéristiques précises de cette musique. Le second album, The Rotter’s Club, est abordé en fin d’article, ainsi que le devenir de chacun des musiciens après la dissolution du groupe. Un entretien avec Dave Stewart (en fin d’article) porte sur les questions de composition et de production du disque. Une telle exploration de cet album permet au lecteur de mieux saisir la richesse de cette production et de la situer dans un contexte plus large, en l’occurrence celui de la Scène de Canterbury.
The Different us. Une représentation de Robert Wyatt
Authors: Costa Jacopo
Published: September 2022

Parmi les musiciens associés à la « scène de Canterbury », Robert Wyatt est sans doute le seul à avoir atteint un niveau de notoriété considérable pendant sa carrière, tout en gardant – paradoxalement – le profil d’une « anti-rockstar ». Dans cet article, j’aborderai la réception de la musique de Wyatt auprès du public « averti »  : en particulier, je me focaliserai sur la correspondance électronique d’une liste de diffusion italienne (composée de musiciens, journalistes musicaux, médiateurs culturels, tous fins connaisseurs de l’œuvre de Wyatt) et sur l’occasion qui en fut le point de départ, à savoir la publication du très controversé The Different You, album hommage à Wyatt réalisé en 1998 par un groupe d’artistes italiens assez connus. L’analyse de cette correspondance sera mise en relation avec les fan studies, et en particulier avec la littérature sur les « anti-fans » et les fanzines, et elle me permettra de discuter les aspects – musicaux, humains, politiques – qui contribuent au succès de Wyatt auprès d’un certain type de public.
Les jeux de timbre : l’alto de Geoffrey Richardson dans For Girls Who Grow Plump in the Night de Caravan
Authors: Zouhir Karam Al
Published: September 2022

Dans cet article, je souhaite montrer l’apport de Geoffrey Richardson, qui joue de l’alto au sein du groupe Caravan – un instrument rarement joué dans le rock progressif. Je vais tenter de souligner les différents styles, influences et modes de jeu que l’étude des morceaux les plus riches au niveau de l’utilisation de l’alto mettent en valeur. Les deux morceaux choisis sont issus de For Girls Who Grow Plump In The Night, le cinquième album de Caravan, sorti en 1973. L’analyse précise d’extraits de morceaux (partitions, gammes, solos, expressions techniques et dynamiques) permet de reconstituer les couleurs et caractères portés par l’alto –de manière générale, dans l’horizon d’un genre musical comme le rock psychédélique, de manière plus particulière, au regard du style de l’école de Canterbury, et enfin au cœur du jeu de Richardson, qui intègre des mélodies inspirées de la country music, de la musique folk, du blues, du psychédélisme, reposant sur différentes échelles musicales (pentatonisme, gammes mineures, modes grecs).
Young Women Survivors Speak About Structural Violence and Vulnerabilities to Human Trafficking
Authors: Oyebanji Kemi , Ngabaza Sisa
Published: September 2022

Human trafficking is a global issue that most countries have battled to control. It is exploitative, abusive, and violates human rights. Generally, it is seen as modern-day slavery. Despite several measures by different countries to combat trafficking, it continues to spread. Although men, women, and children are all vulnerable to trafficking, women and girls are more trafficked due to gendered intersectional factors that place them in vulnerable conditions. This chapter draws on academic work that explored a group of young women's lived experiences of trafficking at a border town in Nigeria. Using a feminist lens and working within a qualitative framework, in-depth interviews were conducted with young women who survived human trafficking. A qualitative thematic analysis was employed for data analysis. The authors draw on these young women's voices to explore how gendered intersectional factors create and perpetuate vulnerability to trafficking. The chapter also argues for the necessity to empower women as a protective measure against trafficking and for social justice.
Resilience as a Protective Factor in Children Exposed to Domestic Violence
Authors: Đurđević Sanja , Zirojević Marijana , Zirojević Srđan , Krivokapić Žilijeta
Published: September 2022

Resilience can be defined as adaptability to change and capacity for successful adaptation, despite challenges and difficult circumstances. Every day a large number of children experience violence, which takes many forms and occurs in different contexts. It is first necessary to distinguish whether the child was directly abused by the parents or the environment or was just present with violence. It is also necessary to pay attention to the age of the child, his level of development, and understanding of violence. These are some of the factors that can affect the consequences in the future. The chapter will explore theoretical and practical aspects on the topic of risks and resilience associated with violence in the family and the environment. The chapter will also present models of resilience, as well as research conducted, which aims to reduce the level of violence against children.
Strategies for Successful Multilingual Online Learning
Authors: Gruber Sibylle
Published: September 2022

Principles of Rhetoric and Writing, a sophomore rhetoric course, is used to show how multimodal project design and formative learning and assessment strategies provided the much-needed motivation to make changes to the initial course design in order to ensure the inclusion of social justice education in an online course for Chinese native students. Multimodal projects encourage teachers to de-emphasize decontextualized standards and skills acquisition and support continuous revisions to an established curriculum and to established learning activities. In addition, formative assessment opportunities included in Principles of Rhetoric and Writing highlight the importance of incorporating text-based and multimodal composing to account for and include the national, social, cultural, racial, gendered, and educational backgrounds of students as well as the teacher.
Fostering Student Self-Awareness and Esteem to Participate and Transform Their Worlds
Authors: Barrón Nancy G.
Published: September 2022

This chapter provides an example of American andragogy with a discussion on why and how to redesign a traditional classroom for college students to gain leadership skills and social justice awareness. Social justice action is especially important for students to research and discuss in order to create an environment where peace, security, and respectful engagement become part of students' leadership skills. After a discussion of American andragogy, the chapter focuses on redesigning spaces, roles, and expectations to create learning spaces that provide students with explicit reasons for participating in alternative learning spaces. The chapter concludes by emphasizing safe spaces and brave spaces as sites to encourage leadership skills and with it social justice awareness.
Social Contact and Adaptation
Authors: Pho Hanh
Published: September 2022

This longitudinal mixed methods study examined the relationship of social contact and socio-cultural, academic, and psychological adaptation outcomes of international students. The study was conducted over 16 months, spanning over the complete sojourn of the students. Surveys were distributed early and near the end of the academic year (N=84), and semi-structured interviews were conducted once students returned home for at least a month (N=13). Findings suggest there was a significant increase of the quantity and quality of co-national and international contact over the academic year. However, the international students tended to socially segregate from “host national” students (UK students) and had difficulties in maintaining the degree of contact over time. The study also confirms the importance of non-co-national international contact in adaptation during the sojourn and re-adjustment to home cultures.
Exploring the Assessment Experiences of Eight Teenage Maltese Boys
Authors: Said Pace Doreen
Published: September 2022

Teaching, learning, and assessment are not silos. Instead, they are the pillars that should be connected by meaningful assessment practices for effective educational gains. Assessment can be meaningful to its users—educators and students—only if they can make sense of what, and why, they are employing certain strategies and techniques. In the intent to contribute to this lacuna, eight 12-year-old male voices attending the same non-state school were captured. A narrative methodological approach has been adopted to provide an enriched understanding of the learners' life experiences of their educational assessment. Virtual interviews were the source of data collection. Findings show different degrees of understanding—narrow, moderate, and broad—and a relationship with the preferred modalities of assessment. Despite the lack of uniformity in the formative assessment (FA) practices adopted by their educators, all the boys see benefits in the use of FA strategies, yet assessment is regarded as a teacher thing rather than a shared partnership between them.

The aim of this chapter is to provide history teachers with digital historical resources and alternative teaching tools that they can use in history education in order to help students gain high-level thinking skills in addition to knowledge in history courses. To achieve this, a needs analysis for Turkish history teachers was performed to determine which subjects should be focused on in history courses, and what kind of digital historical resources and alternative teaching tools are required. The findings have shown that history teachers face difficulties in teaching ancient civilizations. Teachers have expressed that they remain abstract and incomprehensible to the students due to the inefficacy of materials and teaching tools. It has been determined that they need proper digital historical sources and alternatives most fitting for the subject at hand.
The Perceptions of Pre-Service Teachers Regarding the Teaching Methodology of Primary Education Social Science Teachers
Authors: Guerrero-Romera Catalina
Published: September 2022

This chapter has been proposed with the aim of discovering and analysing how Social Sciences teachers represent and develop knowledge in their teaching practice through the perspective of pre-service teachers. To achieve this, the methodological model of primary education teachers will be analysed via observations carried out by students of an undergraduate degree in Primary Education during their period of teaching practice, paying particular attention to the development of the historical thinking skills and the use of ICT resources and of learning strategies, resources, and assessment. These observations by trainees reflect how pre-service teachers are more aware of the importance of encouraging a wider variety of learning and assessment strategies and activities for the achievement of historical thinking competences and more complex thinking skills.
Evaluation of a Training Program for Trainee Teachers in Active Methodologies for Teaching Social Sciences
Authors: Méndez Ramón , Chaparro-Sainz Álvaro , Sánchez Rubén Martínez , Felices-De la Fuente María del Mar
Published: September 2022

The primary purposes of this study are to investigate the opinions and conceptions of primary education teachers undergoing initial training on active methodologies and to evaluate a training program that uses these methodologies with a particular focus on the teaching of Social Sciences. To this end, a mixed methodology has been employed, using an initial questionnaire and a focus group as research instruments. Following the data analysis, the results show a favorable assessment of these active methodologies. There were some gender differences, as women assigned greater value than men to the active strategies, resources, and evaluation approaches and were more focused on competency-based learning. Another result highlighted the suitability of using service-learning or inquiry methodology to teach Social Sciences. The authors conclude that improving the training program developed is necessary, offering more connections with practice and expanding initial teacher training in active methods.
Identifying Buying Patterns From Consumer Purchase History Using Big Data and Cloud Computing
Authors: Ye DanDan , Muthu BalaAnand , Kumar Priyan Malarvizhi
Published: September 2022

The consumer buying process refers to the procedures taken by a buyer when making a purchase. There are patterns that customers follow before they make purchases that can be described as consumer behavior. When making decisions, businesses and engineers turn to big data for the valuable insights it contains. Edge computing, although presenting processing issues, has aided in the evolution of big data by offering computational, networking, and storage capability. The process consists of identifying needs and wants, conducting research, evaluating options, and making a purchase, followed by evaluating the purchase. This is a considered major problem in the prediction history. To overcome these issues, here comes a framework of predicting customer purchasing using big data analytics (PCP-BDA) to determine the purpose of every customer becoming aware of the need or desire for a product and ends with the purchase transaction.
Can Biofilm biofertilizer cut down chemical fertilizers in leafy vegetable cultivation? A case study with Centella asiatica (Gotukola)
Authors: Gangathilaka K. G. S. M. , Premarathna M. , Madawala H. M. S. P. , Seneviratne G.
Published: September 2022

Purpose: In Sri Lanka, a higher usage of chemical fertilizers (CF) has been observed in agriculture which affects negatively for health and wellbeing of consumers as well as environment. Biofilm biofertilizer (BFBF) is a novel technology which is being practiced in many crops to enhance the productivity while improving soil quality. However, the BFBF has not been applied for leafy vegetables thus far. This study was conducted to introduce BFBF to C. asiatica (Gotukola) cultivation as a case study, in order to reduce the usage of CF.
Research method: Firstly, a field experiment was carried out to evaluate the minimum CF rate that would not hamper the yield of C. asiatica cultivation. Then, different combinations of reduced rates of the minimum CF level and BFBF (Biofilm-veg™) were applied with a control of no amendments, and yield was recorded to explore the possibility of CF reduction with the BFBF application. One-way ANOVA, Tukey’s HSD test, and cost-benefit analysis were used to compare the treatments.
Findings: The study revealed that even with only 60% of the farmers’ CF rate, there was no observable yield compromise. Thus, the optimum CF requirement for the crop was identified as 60% of the farmers’ current CF rate. By coupling of BFBF the amount of CF could be brought further down to 48% of farmers’ current CF rate. Furthermore, the application of 48% CF+BFBF produced a plant growth comparable to that with 100% CF.
Research limitations: There were some practical limitations such as long dry spells and also finding suitable fields for the experiment, due to farmers' hesitation on possible yield reduction.
Originality: Application of BFBF is an effective method to cut down CF by half in C. asiatica cultivation, thus minimizing the adverse effects of CF. Several studies have been conducted thus far to analyze the possibility of biofertilization in cutting down CF in agriculture, but they have only been limited to inoculation of isolated soil microbial mixtures. Present study is the first attempt to evaluate the capability of developed microbial biofilm-based BFBF application in reducing CF use in leafy vegetable cultivation.
Antioxidant Capacity and Nutritional Value of Peels and Seeds of Selected Pomegranate (Punica granatum L.) Cultivars from Sri Lanka
Authors: Panapitiya P. D. S. N. H. , Weerasooriya M. K. B. , Punchipatabendhi T. I.
Published: September 2022

Purpose: Nonedible portion of Pomegranate is reported to be rich with a diverse range of phytochemicals which embrace with health promotive features. Though antioxidant power and nutritive value of fruit juice are well known, knowledge of nonedible fraction is very poor. Hence, evaluation of antioxidant power and nutritional value of fruit peel and seed of pomegranates was targeted
Research Method: IC50, Ferric Reducing Antioxidant Power (FRAP), Total Phenolic (TPC), Total Flavonoid (TFC), Total Anthocyanin and pro-anthocyanidin Contents (ProAC) were determined. Nutritional value was studied by proximate analysis. Findings: IC50, TPC, FRAP and TFC values of peels were ranged from 4.6 to 41.1μg/mL, 318±1.77 to 478±5.62 mg Gallic acid equivalent/g, 4.270±0.83 to 6.690±0.15 mM Fe2+/g and 52.64±0.24 to 75.99±0.849 Rutin equivalent mg/g respectively. Antioxidant power and TFC of all the peel extracts were well above as compared with juice and seed samples, the highest IC50 and TPC in Daya peel whereas the highest FRAP and TFC in Nimali and Kalpitiya red peels respectively. Kalpitiya red juice and peel had the highest TAC and ProAc. Proximate analysis revealed that Protein, lipid and fiber contents were higher in seeds than peels. Carbohydrate content of all the peels was higher than the seeds.
Research Limitations: There were some practical limitations such as long dry spells and also finding suitable fields for the experiment, due to farmers’ hesitation on possible yield reduction.
Originality/ Value: Findings reveal that selected cultivars of pomegranate peel possess exceptionally high antioxidant power and could be applied as an excellent source of natural antioxidant in future therapeutic and medicine and as a safer natural antioxidant in food industries. High nutrient contents in pomegranate by-products facilitate to develop nutritionally valuable components such as functional food ingredients and nutraceuticals.
Enhancing in vitro growth of wheat seedlings under water stress using biopriming
Authors: Salih S. , Bahjat N. , Tuncturk R.
Published: September 2022

Purpose: Providing food for the world, growing population becomes more difficult with the increase of abiotic stresses due to climate change. The production of wheat, which is a major crop is under the threat of drought stress. The aim of this experiment was to find out to what extent biopriming reduced the effects of drought on wheat (Triticum aestivum L. cv. Slemani-2) seedling growth under in vitro conditions.
Research Method: In vitro planted seedlings were subjected to drought conditions using three different watering regimes (normal [control], ½ reduced, and ¾ reduced) after biopriming the seeds with Azospirillum lipoferum, Frateuria aurantia, and Chlorella saccharophila. Physiological traits and growth characteristics were measured. ANOVA was performed according to the factorial layout in completely randomized experimental design with three replications using Microsoft Windows based COSTAT software (version 6.3).
Findings: The experiment results showed that biopriming had reduced the effect of drought on chlorophyll concentration and root characteristics, especially under ½ reduced water application. A. lipoferum and C. saccharophila were more beneficial for the seedlings than F. aurantia. Physiological and growth characteristics such as chlorophyll concentration were enhanced using biopriming, hence photosynthesis, root characters, and nutrient uptake.
Research Limitations: The availability of previous studies and data on the microorganisms used werethe main constrain in the study. Conducting a study under controlled greenhouse conditions until harvest might provide more information as more parameters will be measured and data collected, especially at the anthesis stage as it is a crucial stage.
Originality/ Value: This research provides a possible method to reduce drought impact on wheat crops by suggesting biopriming with new microorganisms.
A Study on the Antioxidant and Active Compounds of Gardenia jasminoides Ellis (GJE) Leaves Extract
Authors: Yoga I. B. K. W. , Suprapta D. N. , Jawi I. M. , Permana I. D. G. M.
Published: September 2022

Purpose: The aim of this study was to isolate and identify the active compound antioxidant fractions from Gardenia jasminoides Ellis leaves.
Research Method: The antioxidant activity was determined using DPPH 0.1 mM (1:1), and was analyzed spectrophotometrically. In addition, separation was performed using column chromatography. The most active isolate was identified by UV-Vis, FT-IR, and LC-MS/MS. The quantitative analysis was done in three replicated.
Findings: It was discovered that the antioxidant activity in the semi-polar fraction (IC50 = 62,50 ppm) was higher than both the polar and non-polar fractions. Combining 295 isolates via column chromatography, 11 combined isolates were obtained (fA-fK). The fK isolate had the highest antioxidant activity of 90.38% and IC50 15.74 ppm. It also obtained 2 maximum wavelengths (336 and 275 nm) and could be categorised as flavonoid (flavonol with 3-OH substituted). The FTIR analysis also showed that the fK isolate had functional groups found in flavonoid. Finally, the identification of the fK isolate by LC-MS/MS showed that the compound at retention times of 5,91 and 5,06 minutes were kaempferol 3-O-rutinoside and rutin, respectively.
Originality/ Value: Based on the obtained results, it was concluded that GJE leaves have the potential to be developed as a new and inexpensive source of flavonoids.

Authors: Jamaluddin Dindin , Ainissyfa Hilda , Ratnasih Teti , Nabilah Ebi
Published: September 2022

One way to understand the Qur’an is by translating the message using Pegon script and Nadhom media. One expert who uses the method to teach students is Ahmad Dimyati. The purpose of this research is to investigate Ahmad Dimyati’s works, and one of his works was the translation of the Qur’an using the Pegon script and Nadhom media in the context of Priangan, West Java, Indonesia. This research explores how the media aligns with the socio-cultural condition in which it becomes the crucial point of the research. This research belongs to both textual and field studies since it involves observation and documentation data from Ahmad Dimyati’s manuscript, and interviews with Kyai and Ustadz at Pondok Pesantren Sukamiskin, West Java, Indonesia. In addition, this research uses historical and hermeneutic approaches. The historical approach found that the selection of Pegon scripts and Nadhom media involved the segmentation of readers. At the same time, the hermeneutic approach is used to understand the contents of the text. The data obtained were analysed descriptively. This research found that the translation did not change the original meaning and can bridge the gap between Arabic and Sundanese languages so that the students can better understand the content of the quoted verses of the Qur’an. The selection of Nadhom as a media to translate the Qur’an is accurate as shown in its function that supports the achievement of the goal being revealed in the Qur’an. Thus, the use of Pegon script and Nadhom media to translate the Qur’an can bridge the gap between Arabic and Sundanese languages.Contribution: This research contributes to transferring the Qur’an translation into another language, making it easier for the reader to understand the content.
Nature and human being, a renaissance of the 20th century
Authors: Van den Hoogen Toine
Published: September 2022

As our scientific conscience about nature has been deeply changed by the development of so-called ‘quantum theory’ during the 20th century, theology has been confronted with a new horizon of questions about ‘God’ and about how a human being has to be imagined in our cosmos. This article is a tiny comparison between the renaissance of thinking in line with the rediscoveries of Aristotelian thought in the West during 12th century and the renaissance of science we are witnessing in our age.Contribution: In this series of contributions about theology and nature, this article contributes to a way of questioning theology and nature in a new, dazzling perspective about rerouting humanity in recent research about the smallest measurable values in nature, being perhaps a new topos of theological reflection that is characterised by God and contingency.
Anglican cathedrals and implicit religion: Softening the boundaries of sacred space through innovative events and installations
Authors: McKenna Ursula , Francis Leslie J. , Stewart Francis
Published: September 2022

High profile (and controversial) events and installations, like the Helter-Skelter in Norwich and the Crazy Golf Bridges in Rochester, have drawn attention to innovation and public engagement within Anglican cathedrals. The present study contextualised these innovations both empirically and conceptually. The empirical framework draws on cathedral websites to chronicle the wide and diverse range of events and installations hosted by Anglican cathedrals in England and the Isle of Man between 2018 and 2022. The conceptual framework draws on Edward Bailey’s theory of implicit religion to classify and to explore these events and installations. Two insights from the theory of implicit religion emerged as of particular significance. First, the notion of implicit religion softens the boundaries between the sacred and the secular. This was exemplified by eight categories of events: scientific exhibitions, festivals, musical events, art exhibitions, theatre, markets, community events and installations. Second, the notion of implicit religion draws attention to the themes and activities that generate meaning and purpose. This was exemplified by seven themes: social justice and social conscience, violence and reconciliation, remembrance, migration and sanctuary, COVID-19 and lockdowns, personal well-being and nature and environment.Contribution: Situated within the science of cathedral studies, this article identifies the range of innovative events and installations hosted by Anglican Cathedrals in England and the Isle of Man and assesses the significance of these events and installations through Edward Bailey’s lens of implicit religion, discussing first the softening of boundaries between the sacred and the secular and then the generation of meaning and purpose through the core themes raised by these events and installations.
Lead levels of new solvent-based household paints in Zimbabwe and Botswana: A preliminary study
Authors: Kambarami Rose A. , Coulter Lucia L. , Chikara Mudawarima Louisa , Kandawasvika Gwen , Rafferty Jack , Donaldson Clare , Stewart Benjamin
Published: September 2022

Background: Lead paint remains a major potential source of lead poisoning globally, but there has been no documentation on lead content in solvent paints available on the markets in Zimbabwe and Botswana.Aim: To determine the lead content of solvent-based paints available on the market in Zimbabwe and Botswana and identify a need for a larger study to inform policy.Methods: This pilot study was conducted in Harare, Zimbabwe, and Gaborone, Botswana. Popular brands of solvent-based household paints were bought from hardware shops in Harare (10 samples) and Gaborone (19 samples). Samples were analysed for lead content using inductively coupled plasma-atomic emission spectrometry.Results: Seventy percent of samples from Zimbabwe were found to contain lead above 90 parts per million (ppm), the recommended regulatory limit, with ranges from less than 60 ppm to 12 000 ppm. Twenty percent of Zimbabwean samples had lead levels above 10 000 ppm. No samples from Botswana had lead concentration above the detection limit, with all levels below 100 ppm.Lesson Learnt: Data strongly suggest very high lead content in popular brands of solvent paints in Zimbabwe, indicating a need for a larger, well-designed study for policy direction.
The relationship between investor tax preferences and the payout methods of JSE listed companies
Authors: Nel Rudie , Wesson Nicolene , Steenkamp Lee-Ann
Published: September 2022

Background: Investor tax preference parameters have been included as an explanatory variable for changes in payout methods in developed countries. There is, however, a lack of research in this area in developing countries. Tax reform in South Africa – comprising a change in the tax regime and successive increases in tax rates – offers a unique setting to examine investor tax preference parameters as a contribution to literature.Aim: This study investigated the relationship between investor tax preference parameters (of individuals, corporates, and institutions) and payout methods (namely dividends, capital distributions, additional shares, and share repurchases).Setting: The study used data collected in respect of companies listed on the Johannesburg Stock Exchange (JSE) in South Africa for the financial reporting periods ranging from 2012 to 2019.Method: A regression analysis of panel data was employed to relate the changes in payout methods to changes in profits, investor tax preference parameters, the lagged levels of variables, and ownership concentration dummy variables.Findings: The empirical evidence of this study revealed that investor tax preferences affected dividends as a payout method. This accordingly suggests that the tax differential of dividends and capital gains affect the supply of dividends in South Africa.Conclusion: The study contributes empirical evidence in support of the taxes and tax clienteles theory from a developing country perspective. This could suggest that tax reform in a developing country, in this case, South Africa, has a more pronounced effect on payout methods than in developed countries.

Stereotactic breast biopsies: Radiological-pathological concordance in a South African referral unit
Authors: Alexander Natasha , Viljoen Ilana , Lucas Susan
Published: September 2022

Background: Stereotactic breast biopsies have become the gold standard for tissue diagnosis in non-palpable, sonographically occult breast abnormalities seen on mammogram. Only limited data exist in South Africa on the correlation between imaging findings and stereotactic biopsy histology.Objectives: To describe the mammographic findings and histological diagnosis in patients who underwent stereotactic breast biopsy at a referral hospital. In addition, to evaluate the proportion of malignancy in each Breast Imaging Reporting and Data System (BI-RADS) category.Method: A retrospective review of stereotactic breast biopsies was performed. Imaging characteristics (including BI-RADS category) and histological diagnosis were recorded. Using histopathology, cases were classified as benign, high-risk or malignant.Results: A total of 131 biopsies, from 123 patients, were included in the study. Most biopsies were performed on asymptomatic patients (79.3%, 104/131). The majority were categorised as BI-RADS 4 and demonstrated calcifications. Histology revealed a malignant diagnosis in 40 (30.5%) patients, a high-risk lesion in 8 (6.1%) patients and a benign diagnosis in 83 (63.4%) patients. There was a stepwise increase in the proportion of malignancy from BI-RADS category 3 to 5. When compared with surgical histology, the stereotactic biopsies demonstrated an overall ductal carcinoma in situ (DCIS) underestimation rate of 10.3%.Conclusion: Despite resource restrictions, stereotactic breast biopsies performed in a South African context produce radiological-pathological concordance in keeping with BI-RADS guidelines, as well as with local and international studies.
