We present the discovery of a large extended radio jet associated with the extremely radio-loud quasar J1601+3102 at z ∼​​​​​ 5 from subarcsecond resolution imaging at 144 MHz with the International LOFAR Telescope. These large radio lobes have been argued to remain elusive at z > 4 due to energy losses in the synchrotron emitting plasma as a result of scattering of the strong cosmic microwave background at these high redshifts. Nonetheless, the 0

3 resolution radio image of J1601+3102 reveals a northern and a southern radio lobe located at 9 and 57 kpc from the optical quasar, respectively. The measured jet size of 66 kpc makes J1601+3102 the largest extended radio jet at z > 4 to date. However, it is expected to have an even larger physical size in reality due to projection effects brought about by the viewing angle. Furthermore, we observe the rest-frame UV spectrum of J1601+3102 with Gemini/GNIRS to examine its black hole properties, which results in a mass of 4.5 × 108
M
⊙ with an Eddington luminosity ratio of 0.45. The black hole mass is relatively low compared to the known high-z quasar population, which suggests that a high black hole mass is not strictly necessary to generate a powerful jet. This discovery of the first ∼​​​​​100 kpc radio jet at z > 4 shows that these objects exist despite energy losses from inverse Compton scattering and can put invaluable constraints on the formation of the first radio-loud sources in the early Universe.
Assessment of awareness about contraception among a sample of Iraqi women using hormonal contraceptives: a cross-sectional study
Authors: Salh Fatima Mahdi , Abdulridha Manal Khalid
Published: February 2025

Non-adherence to hormonal contraceptives is often due to lack of information, fear of adverse effects, and social and religious stigmas. The aim is to assess the women’s awareness and adherence to hormonal contraceptives among women of childbearing age and also to track the adverse effects of hormonal contraception. A cross-sectional, community-based study involved 80 women who were assessed for the level of women’s awareness and adherence using a validated Arabic questionnaire. Women had moderate levels of knowledge about hormonal contraceptives (46.25%), a neutral attitude level constituted the majority of women’s responses (52.5%), and a good practice level (53.75%). Most of the women (68.75%) had good adherence levels. Higher levels of non-adherence were associated with mood swings (84%) and depression (84%). There was a strong direct correlation between awareness score and higher adherence score. Regarding the education levels of wives, there was a direct significant correlation between awareness scores and higher adherence scores. In conclusion, the women had moderate knowledge, neutral attitudes, and good practices about contraception, mainly due to university education. Adherence to hormonal contraceptives was positively associated with good awareness.
Honoring the Afro-Colombian musical culture with the naming of Epipedobates currulao sp. nov. (Anura, Dendrobatidae), a frog from the Pacific rainforests
Authors: Betancourth-Cundar Mileidy , Ríos-Orjuela Juan Camilo , Crawford Andrew J. , Cannatella David C. , Tarvin Rebecca D.
Published: February 2025

The number of amphibian species described yearly shows no signs of slowing down, especially in tropical regions, implying that the biodiversity of amphibians remains woefully underestimated. A new species of poison frog is described from the Pacific lowlands of southwestern Colombia: Epipedobates currulaosp. nov., named for the Pacific music and dance genre known as "currulao" or "bambuco viejo". This species inhabits lowland forests from 0–260 m a.s.l. This taxon differs from congeners by having a combination of bright yellow blotches in the dorsal anterior region of the thigh and upper arm, homogenous dark-brown dorsal coloration, and advertisement calls of long duration and many pulses. We also describe the courtship call of E. currulaosp. nov., which is lower in frequency and shorter in duration than its advertisement call. Molecular phylogenetic analyses confirm the monophyly of the populations sampled and its position as the sister species of Epipedobates narinensis, which occurs in southwestern Colombia. Among species of Epipedobates, the new species has been previously confused with E. boulengeri, but the two species are allopatric and represent two divergent clades (1.77% divergent for 12S–16S and 5.39% for CYTB). These species can be distinguished by the presence of a bright yellow blotch on the dorsal anterior region of the thigh and on the upper arm of E. currulaosp. nov., blotches that are either more white than yellow or absent in E. boulengeri. In addition, the advertisement calls are distinct, with E. currulaosp. nov. having a single but long call in each call series while E. boulengeri has 2–6 calls in a series with each call being much shorter in length. Epipedobates currulaosp. nov. is the most northern species of Epipedobates, which extends southwards along the western edge of the Andes. Known as the Chocó, this biogeographic region has been largely converted to agriculture in Ecuador and is experiencing widespread transformation in Colombia, which may endanger E. currulaosp. nov. and biodiversity in the region. A Spanish translation of the main text is available in Suppl. material 8.
Mutatus gen. nov., a new genus of Phrurolithidae (Arachnida, Araneae) from China, with descriptions of four new species
Authors: Mu Yannan , Wang Luyu , Zhang Feng , Zhang Zhisheng
Published: February 2025

Mutatusgen. nov. is described from southwest China, including four new species: M. gelaosp. nov. (♂♀, Guizhou Province), M. tianyansp. nov. (♂♀, Hubei Province), M. tujiasp. nov. (♂♀, Hubei Province), and M. yintiaolingsp. nov. (♂, Chongqing Municipality). This new genus can be differentiated from other phrurolithid genera by the male palp which has a prolateral tegular apophysis and tegular sheet, and by a small protuberance on the female epigynal plate.
Phylogenomics of North American cybaeid spiders (Araneae, Cybaeidae), including the description of new taxa from the Klamath Mountains Geomorphic Province
Authors: Hedin Marshal , Ramírez Martín J. , Monjaraz-Ruedas Rodrigo
Published: February 2025

The systematics of humble-in-appearance brown spiders (“marronoids”), within a larger group of spiders with a modified retrolateral tibial apophysis (the RTA Clade), has long vexed arachnologists. Although not yet fully settled, recent phylogenomics has allowed the delimitation and phylogenetic relationships of families within marronoids to come into focus. Understanding relationships within these families still awaits more comprehensive generic-level sampling, as the majority of described marronoid genera remain unsampled for phylogenomic data. Here we conduct such an analysis in the family Cybaeidae Banks, 1892. We greatly increase generic-level sampling, assembling ultraconserved element (UCE) data for 18 of 22 described cybaeid genera, including all North American genera, and rigorously test family monophyly using a comprehensive outgroup taxon sample. We also conduct analyses of traditional Sanger loci, allowing curation of some previously published data. Our UCE phylogenomic results support the monophyly of recognized cybaeids, with strongly supported internal relationships, and evidence for five primary molecular subclades. We hypothesize potential morphological synapomorphies for most of these subclades, bringing a robust phylogenomic underpinning to cybaeid classification. A new cybaeid genus Siskiyugen. nov. and species Siskiyu armillasp. nov. is discovered and described from far northern California and adjacent southern Oregon and a new species in the elusive genus Cybaeozyga, C. furtivasp. nov., is described from far northern California.
On Derivational Productivity in Slovene with Notes on Lexical Frequency and Awareness of the Norm
Authors: Priestly Tom
Published: February 2025

The major aim of the study reported here was to discover a way of measuring the productivity of derivative patterns or processes, a task which appears never to have been accomplished for any language before. As specific material for the study, two contrasting deadjectival verbal derivative patterns were chosen: the 'inchoative' -eti and the 'factitive' -iti, as occurring in, e.g., rjav 'brown', rjaveti 'to become brown', rjaviti 'to make (someone or something) brown.' The method involved psycholinguistic tests, administered in Ljubljana in 1993—94. The subjects for the tests in 1993 were 186 secondary and 180 post-secondary students. For the 1994 follow-up study the tests were limited to three groups of university respondents, totalling 116 in all. Cues comprised four questions: (1) Ali se po vašem beseda nahaja v knjižni slovenščini? (2) Ali vi to besedo kdaj uporabljate? (3) Ali je ta beseda po vašem možna in razumljiva? (4) Kako pogosto sami uporabljate to besedo? Subjects selected responses on five-point Likert scales; the data were analyzed statistically.
As far as productivity is concerned, there are three conclusions. First, it is clear that, at least for these derivative patterns, productivity is a "cline,'' but in two quite distinct meanings of the term. First and most obviously, one process may be synchronically more productive than another. Second, what may be called the productive strength of any one process also varies. To take just two examples from the mean responses to question (3), we see that the cue godneti was assessed, on average, as extremely "possible and understandable," while at the other end of the scale the cue plašeti was assessed, on average, as well nigh impossible and incomprehensible; the remaining cues are strung out along the cline in between the two.
Language Change in a Contact Situation: The Case of Slovene in North America
Authors: Šabec Nada
Published: February 2025

The article discusses the linguistic situation among immigrants of Slovene descent in the United States of America and Canada. Owing to the geographic distance between Slovenia and the host country and particularly to the very strong influence of the pragmatically dominant English, Slovene there is undergoing a very specific kind of development.
Data collected through empirical research (interview excerpts) are analyzed in order to identify contact-motivated changes of Slovene. These are encountered in all types of bilingual discourse (borrowing, code switching, English-influenced monolingual Slovene) and on different linguistic levels from phonology to semantics and pragmatics. The most salient areas of English linguistic impact, however, are morphology with its simplification, regularization and/or even deletion of Slovene inflectional system, and syntax with its gradual adoption of English-like SVO word order patterns.
On a sentence level these kinds of structures constitute what could be termed a composite matrix language, made up from the features of both languages. Development, though, stops short of the so-called matrix language turnover (MLT), because it is interrupted by a very rapid process of language shift from Slovene to English. This has been accomplished in the course of three generations in the case of pre-war immigrants and even faster in the case of post-war ones. The variety of Slovene in this particular context is therefore of a very temporary and unstable nature and defies the postulation of rigid structural constraints on it. It nevertheless represents a distinct contact variety of Slovene well worth further research because of the likely insights into the language change mechanisms that it may provide.
The Western South Slavic Contrast Sn. sah-ni-ti // SC sah-nu-ti
Authors: Andersen Henning
Published: February 2025

The paper reexamines the traditional explanation for the "idiosyncratic development'' of the Common Slavic Class II verbs with the aorist and/or infinitive suffix -nǫ-, attested in OCS sъxnǫti 'dry', P schnąć, R soxnut', SC sahnuti, but in Slovenian as sahniti. The peculiarity that gave rise to this development in Slovenian is generally thought to be simple analogy with the Class IV verbs, e.g., braniti 'defend'. In the course of this reexamination, the author shows how the "idiosyncratic development," once restated, fits in with data from other Slavic languages. Rather than proceeding from the assumption that the -nǫ type was replaced by -ni-, the author demonstrates that it is reasonable to depart from a Common Slavic dialect difference -nǫ// -ny (< Early Common Slavic innovative *-nū-n// archaic *-nū -), which probably had its origin in the period before the Slavic Migrations. These by-forms could thus have given rise to the variation that is found in the modern Slavic dialects. This variation was transported with the Slavs who colonized the Western South Slavic and West Slavic territories in the 400—700s and in turn gave rise to sociolinguistic competition between the alternatives in the following centuries. These findings are shown to correlate well with recent advances in the identification of the major routes of migration taken by the Slavs, which progressed up the Danube, into Pannonia and Noricum, up the Morava to Upper Silesia, across the Bohemian Basin and through the Elbe River Gorge to the Ore Mountains in Upper Lusatia; then beyond, down the Elbe to the eastern border regions of the later principality of Hannover and along the banks of the lower Elbe. Working back from these routes, the author suggests that the Early Common Slavic *-nū forms may have characterized dialects somewhere in the present-day East Slavic language area, probably a relatively small region long since repopulated with speakers of *-nǫ dialects.
Multiple Causation in the Spread and Reversal of a Sound Change: Rhotacism in South Slavic
Authors: Greenberg Marc L.
Published: February 2025

The paper treats the change ž > r ("rhotacism") in the South Slavic languages, such as that, e.g., found in the present tense of the verb *mòže(tъ) > Sn mó.re, Cr/Bs dialect more; complementizers, e.g., *kako ž(e) > Sn kakor; in various adverbial formations, e.g., *bože > bore; and, in some Sn and Cr/Bs dialects, the present tense of the verb (*gъnati:) *žene(tъ) > rene. The origin of the change has been treated variously as a phonetic or a morphological (analogical) change, though neither explanation can account for the limited realization of the change (i.e., it is restricted to a small number of lexical items and grammatical categories) and the vastly differing areals of the change for each item in which it occurs. The present paper argues that the origin of the change is phonetic and follows from a tendency to favor vocalic distinctive features (in contrast to N-Sl developments), a notion that goes back to a pre-War paper by Isačenko. Nevertheless, the spread of the change, and its reversal, can be partially explained by morphological factors. One factor is that uniform environments (e.g., the present tense morem, moreš...) favor its spread vs. alternating environments (-žene/-rene) which have reversed or inhibited it. Another factor is support for the spread of -r as a productive complementizer and temporal marker on the models of metanalyzed forms *kъte/o-r'which' and *veče-r 'evening', respectively. Taboo seems to play an additional role in preserving r-forms in the interjection borme 'my God!'. The reversal of the change in Štokavian may have been due to stylistic considerations, where r-forms were felt to be distinctly western, Catholic, in contrast to ž(e) forms. This observations follows from the fact that r-forms disappear in Štokavian in precisely the forms in which they were productive in Čakavian, Kajkavian and Slovene, namely, the complementizers and temporal adverbs. Finally, those forms which represent semantic innovations, such as morati 'must', jer 'for, because' are best preserved, even in Štokavian, where the r-forms are lexicalized as such.
Football des jeunes, mobilité ascendante et stratégies parentales en Chine
Authors: Dong Hui , Li Yutong , Peng Xiaoqian
Published: February 2025

En Chine, l’expansion du système de formation des jeunes au football a établi un mécanisme de progression pour les apprentis footballeurs, tout en façonnant un nouveau paysage en matière de pratique du football, de choix d’école et de planification éducative à long terme. Cet article révèle qu’à l’évidence, l’initiative venue d’en haut est une entreprise politique et sociale aux bénéfices éducatifs complexes et avec des conséquences sociales sur les parents de différents milieux et leur progéniture. Le contexte éducatif chinois, marqué par une forte compétition, transforme la pratique du football des jeunes en monnaie d’échange pour les catégories sociales favorisées, désireuses de s’assurer des opportunités éducatives prestigieuses, et en bouée de secours pour les groupes marginalisés en quête de voies d’accès élémentaires à l’éducation dans les métropoles. La recherche d’un véritable équilibre entre les objectifs nationaux et les aspirations de la population demeure un problème de taille qui requiert davantage d’innovations systématiques en matière de gouvernance.
« Le César du meilleur empereur a été décerné à César… Avé moi ! ». La représentation de César en chef de guerre dans la culture de masse contemporaine
Authors: Perrot Gaëlle
Published: February 2025

Résumé : Dans la culture populaire, César est presque exclusivement figuré comme un général efficace, triomphant et vertueux. Notre représentation contemporaine est modelée par la définition de uirtus romaine, mais elle doit aussi à l’esthétique des premiers péplums et aux transformations successives de la virilité hégémonique depuis la fin de la seconde guerre mondiale. De son apparence physique, façonnée pour la victoire militaire, à ses actes glorieux, César est porté sur tous les écrans comme un leader inspirant capable de garantir l’esprit de corps et la morale de ses hommes, mais aussi comme un génie de la stratégie.

In this article, sufficiently well-preserved wrecks of sewn and mortise-and-tenons boats will be considered in order to tackle the question of continuity and innovation within shipyards of the Adriatic region.
Alteridad en la literatura periplográfica griega: el caso del Periplo del mar Eritreo
Authors: Albaladejo Vivero Manuel
Published: February 2025

Resumen: El Periplo del mar Eritreo es una obra perteneciente al género periplográfico, que presenta cierto grado de elaboración literaria o, al menos, de utilización de tópoi habituales en la literatura geográfica y etnográfica griegas. Es el caso de la descripción de la forma de vida de diversos pueblos a través de su alimentación. Asimismo, encontramos referencias a ciertos comportamientos peligrosos, como el recurso a la piratería, que, a través de otros autores clásicos, sabemos que era frecuente en el mar Rojo y el océano Índico. Finalmente, cabe destacar la primera referencia en la literatura griega a China, contemplada como un país remoto, al que costaba un enorme esfuerzo llegar y que solamente tenía contacto con sus vecinos.

El ideario oligárquico-tanatocrático de Critias. La eliminación del adversario político para la salud de la pólis
Authors: Donoso Johnson Paulo
Published: February 2025

Resumen: Las fuentes antiguas son ambiguas en la representación que hicieron de Critias. En este trabajo se aborda el Critias que Jenofonte describe en Helénicas. A partir de la lectura de Jenofonte y de otras fuentes, es posible diseñar una imagen de un líder cuyo proyecto político no consistía en la derrota del enemigo sino en su total aniquilación. Los ejemplos más evidentes son la condena a muerte de su amigo Terámenes y la profanación de los restos del Frínico. Para Critias un proyecto refundacional de la pólis requería una adhesión total a los valores oligárquicos.

O diálogo entre medicina e filosofia em Plutarco e Galeno: marcas identitárias
Authors: Pinheiro  Joaquim
Published: February 2025

Resumo: Na Antiguidade Clássica, os limites entre medicina e filosofia não estavam definidos como na actualidade. Pela conexão entre corpo e alma, encontramos reflexões sobre o ser humano nesses dois domínios, como sucede em Galeno e Plutarco. Também é possível encontrar nesses textos marcas revelantes sobre a identidade cultural, nomeadamente sobre a relação entre médico e paciente, o perfil dos intervenientes, bem como a sua origem social, ou a forma como se entendia a arte médica, numa perspectiva mais técnica ou mais filosófica. Na verdade, a medicina, tal como a filosofia, gera uma relação dialógica com vista ao conhecimento.
Les reliquaires et les reliques de Mašreqi
Authors: Tarzi Zemaryalai
Published: February 2025

Résumé : Ce formidable ensemble de reliquaires et reliques inédit qui fait l’objet de notre recherche provient de l’est de l’Afġānestān, mais ne connaissant pas avec exactitude le lieu ou le site de sa découverte, nous lui avons attribué un nom d’emprunt : Mašreqi (ancien nom de la province orientale de l’Afġānestān équivalent du Grand Est français au lieu de l’habituel Ĵalālābād). Pourquoi cette précaution sur le choix d’un tel nom de lieu ? Parce que la plupart des découvertes de ce type de reliquaires ont été faites, à quelques rares exceptions près, sur le sol des faubourgs de l’ancienne ville de Ĵalālābād (Nagarahāra) dont les plus connus sont ceux de Bimārān 2 et Pasāni 2. En effet, ce genre d’ensemble de reliquaires comprenait généralement un reliquaire mère fait en stéatite ou en schiste contenant en son sein, ou accompagné, d’autres reliquaires de petites tailles sans oublier les reliques. Le reliquaire mère de Mašreqi (n° 1) est en stéatite, ses reliquaires de petites tailles (n° 2-11) sont en or, argent et alliage d’argent et de cuivre, sans oublier leurs reliques (n° 12-14p) composées de manuscrits, monnaies et gemmes. Le reliquaire mère de Mašreqi (n° 1) a des affinités artistiques et techniques avec six autres reliquaires mères de la même région, déjà connus, et ensemble ils forment un groupe à part qu’on peut dater du début du ier siècle au milieu du iiie siècle après J.-C. Par ailleurs, la technique des granules des boutons de préhension des petits reliquaires métalliques confectionnés dans des métaux précieux de Mašreqi propose une évolution lente et sûre et se place dans le courant artistique et technique du ier millénaire avant J.-C.

Il “mestiere degli stranieri”. Profumieri egiziani ad Atene tra V e IV secolo a. C.
Authors: Squillace Giuseppe
Published: February 2025

Riassunto: Negli studi sui profumi antichi rimangono quasi completamente nell’ombra i profumieri in grado, attraverso la loro arte, di ‘costruire’ una nuova fragranza. Ciò dipende sia dalla scarsa documentazione disponibile, sia del fatto che le fonti, soprattutto quelle letterarie che forniscono più dati, menzionano spezie e profumi e quanti in vario modo e in diverse epoche se ne servirono, ma lasciano nell’ombra i profumieri, la cui identità e le cui competenze solo in pochi casi sono svelate. Questo contributo cerca di fare luce su alcuni profumieri ateniesi di V e IV secolo a. C. sui quali la tradizione è stata meno avara.

En confrontant les archives (municipales, départementales, nationales, diocésaines et militaires des différents pays belligérants) avec toute une littérature d’interprétations (poèmes, romans, récits, correspondances, témoignages), Chantal Dhennin-Lalart élabore le récit d’une histoire sociale, économique et culturelle du sud des Weppes (Nord de la France) pendant la Grande Guerre. Cette démarche est complétée par l’étude de l’inscription de la Grande Guerre durant tout le xxe siècle jusqu’à aujourd’hui : qu’en reste-t-il 20 ans après, 60 ans après, 100 ans après ? La Grande Guerre est visible dans les paysages et l’environnement géographique autant que dans les souvenirs familiaux réactivés.
Harnessing Pedagogical Content Knowledge for Cross-Disciplinary Innovation in Engineering
Authors: Kareemullah H. , Gift M. D. Mohan , Bhaskaran R. , Krishnan T. Santhana , Senthil kumar S.
Published: February 2025

The chapter will present the integration of PCK toward the fostering of cross-disciplinary innovation within engineering. Being itself the composite of content expertise with effective teaching strategies, PCK acts as the main ingredient in developing holistic approaches to education that transcend traditional boundaries. On the basis of PCK, educators will be able to design curricula that enhance not only disciplinary-based understanding but also interdisciplinary collaboration. The chapter shares cases on how PCK-driven approaches to engineering education will let learners solve complex problems creatively and think innovatively about a wide range of contexts. It also provides strategies for embedding PCK in engineering programs through collaborative projects, interdisciplinary workshops, and experiential learning opportunities.

Leveraging a Scholarship of Teaching and Learning Values Framework to Build Online Faculty Learning Communities
Authors: Moldavan Alesia Mickle , Reagan Kevin J. , Botnaru Diana , Brady Anna C. , Nafziger Bailey , Mesenbrink-Sainz Jackie
Published: February 2025

Scholarship of Teaching and Learning (SoTL) enhances teaching practices and improves student learning outcomes while fostering a culture of continuous professional development and reflective practice (Felten, 2013; Hutchings et al., 2011; Trigwell et al., 2000). Faculty Learning Communities (FLCs) serve as dynamic hubs for collaborative exchange, enabling faculty to engage with SoTL principles, share diverse perspectives, and develop innovative teaching strategies that benefit learners (Cox, 2004). This chapter examines an online SoTL FLC at a multi-campus institution as a case study to propose a SoTL Values Framework to guide best practices in online professional development. The framework is built on four key values: inclusivity, collaboration, scholarly approach, and reflectiveness, each aligned with unique opportunities offered by the online environment. By drawing on SoTL literature and reflecting on the experiences within this online SoTL FLC, the chapter offers insights to inform future online SoTL initiatives fostering sustained growth in SoTL practices.
Elaborative Encoding as a Teaching Tool in Online Learning Environments
Authors: Froehlich Alyson
Published: February 2025

This chapter surveys elaborative encoding as a tool for enhancing learning in online environments. By connecting to-be-learned information to learners' pre-existing knowledge, elaborative encoding facilitates deeper understanding and better retention of materials ranging from simple to complex. Research on elaborative encoding has explored various methods applicable to online learning environments; five will be examined here: elaborative interrogation, self-explanation, use of the self-reference effect, use of analogies, and etymological elaboration. The chapter shares practical ideas to encourage elaborative encoding in learners, considering both synchronous and asynchronous elements. The goal is to equip instructors with effective techniques to foster meaningful and memorable learning in their online learning environments.

Published: February 2025

Amidst the global pandemic of Covid-19, the shift towards online learning has become inevitable for students, especially for those who will sit for the Baccalaureate exam -secondary school graduation exam. To address this, a web-designed research method was opted for to develop an online flipped virtual classroom that can enhance secondary school students' engagement and provide them with the adequate assistance needed to prepare for this crucial exam. The web-driven solution was refined in every iteration through the continuous feedback of 52 students from 8 different provinces in Algeria. By the end, 25 secondary school teachers were invited to the Facebook group to share their perspectives on this web-enhanced online method of teaching and validate the framework through a self-reported questionnaire. The findings report an approved framework of how to practically leverage the flipped model in an online-only setting along with the implications it holds on a local and global scale.
Human-Centric Innovation
Authors: Balaji K.
Published: February 2025

Human -centric innovation is paramount in building sustainable organizations in the era of Industry 5.0. As businesses transition from purely technology-driven models to those that integrate human creativity and advanced technologies, a new paradigm emerges—one that places human well-being, ethical considerations, and sustainability at its core.

The main research objective is to investigate the relationship between Psychological Capital (PsyCap), and Servant Leadership (SL) with Organizational Citizenship Behavior (OCB) in NGOs operating in Turkey. The research is quantitative research conducted by a survey distributed to people working in NGOs in Turkey. The collected sample was 201 valid responses. The research hypotheses were tested using Smart PLS (v. 3.2.8), adopting a significant level of 95% two-tailed. It has been found that SL is positively related to OCB in NGOs and PsyCap mediates this relationship. The research finding suggests that to maintain a high level of OCB, NGOs are mainly required to enhance SL among their leaders and to maintain a high level of positive PsyCap among their employees. To overcome the research limitations, it is recommended that future studies develop and examine special scales for organizational behavior concepts prepared specially for NGOs and test the current research model in different regions and within a longitudinal study.

The availability of clean and safe water for drinking is essential for human life and existence, which ideally should be suitable for consumption and not contain pathogenic microorganisms, or any contamination leading to pollution. Water treatment systems are integral to modern water purification processes, yet they are frequently challenged by biofouling. Biofouling continues to be a major obstacle in water treatment systems, resulting in decreased efficiency, higher energy usage, and increased operational expenses. Therefore, this study aimed to determine the bacteriological characteristics of drinking water by isolating and identifying bacterial strains from water samples contributing to biofouling. Samples were obtained from water treatment systems (WTS) at different locations in Malaysia. Selected isolates of unique bacterial strains were identified and assigned their accession numbers. Phylogenetic analysis revealed that these isolates were related to Bacillus cereus,Stenotrophomonas maltophilia, and Stenotrophomonas pavanii species, suggesting that deterioration in water quality from the source, human error, and technical failure may cause decline even if the most desirable treatment systems and disinfection procedures applied.
The Concept of Optimizing the Environment and Moving towards Sustainable Development Goals with Green Infrastructure
Authors: Chang Fu Ming
Published: February 2025

At this stage, the United Nations has established the Sustainable Development Goals (SDGs) to guide global sustainability goals. In order to improve the environment and achieve the goal of sustainable development. This study mainly uses green roofs, the most common among green infrastructures, as the object of study. Green roofs are an auxiliary facility commonly developed on general buildings. They can reduce flood flow and increase water storage capacity through infiltration. This study mainly uses indoor experiments, using green roofs as experimental facilities to simulate the effect of increasing infiltration. The experiment uses an indoor rainfall machine, sets situational simulation conditions as the inflow flow, and uses common grass species as planting. The final experimental results show that this experiment mainly uses a horizontal slope of 0% as the condition for a flat roof. The infiltration rate is as high as more than 50%, and the flood peak can be reduced by more than 30%. Therefore, in the initial design of the building structure, green roof facilities can be considered to achieve the water retention effect through the infiltration rate and reduce the peak flood. It can later be used as a reference for water retention in the building base.

Tattooing is a widespread practice among the population, particularly among young people. With the increased popularity of tattoos, there have also been several reports of acute and chronic adverse events after tattooing. Malignant melanoma cases arising from tattoos have been increasingly described; however, there is no clear relationship between this practice and tumorigenesis. We present a case of two synchronous melanomas (one located on a decorative tattoo) and update the literature.

Secondary mitral regurgitation (SMR) is associated with increased hospitalizations and mortality. Clinical trials comparing mitral valve transcatheter edge-to-edge repair (M-TEER) with guideline-directed medical therapy (GDMT) show conflicting results, but the RESHAPE-HF2 trial offers new insights. This study aims to assess the M-TEER effect in addition to GDMT in reducing all-cause mortality, cardiovascular death, and heart failure hospitalizations (HHF) in patients with SMR when compared to GDMT alone. On September 2, 2024, PubMed, Cochrane CENTRAL, Scopus, and Web of Science were searched for randomized controlled trials comparing M-TEER in addition to GDMT with GDMT in SMR patients with heart failure. A study-level random-effects meta-analysis was conducted using trial-reported point estimates. Seven records from three trials (COAPT, MITRA-FR, RESHAPE-HF2) involving 1426 participants were included. At 24 months, M-TEER (using MitraClip®) significantly reduced the first HHF [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.45-0.96] and all HHF (HR 0.63, 95% CI 0.49-0.81). However, no significant reduction was observed in all-cause mortality (HR 0.76, 95% CI 0.57-1.01) or cardiovascular death (HR 0.77, 95% CI 0.56-1.06). The intervention group had more patients in the New York Heart Association class I/II at 12 and 24 months but no significant improvement in 6-minute walk test performance at 12 months. High trial heterogeneity requires careful interpretation of pooled estimates. Differences in medical therapy and patient characteristics likely affected outcomes across trials. While M-TEER demonstrates benefits in reducing HHF, its effectiveness in reducing mortality remains inconclusive. The degree of left ventricular enlargement may have influenced outcomes, underscoring the importance of careful patient selection.

Authors: Naidoo Shane , Naidoo Nirmala
Published: February 2025

Background: The global rise in the older population, especially in sub-Saharan Africa, has heightened the impact of non-communicable diseases (NCDs), responsible for 74% of global deaths and the leading cause for years lived with disability. Physical activity (PA) has proven to manage NCDs; however, 80% of older adults in sub-Saharan Africa engage in low-to-moderate PA levels.Objectives: This literature review explores current evidence on the effects of PA on ageing and NCDs in older people in sub-Saharan Africa. Insights gained will enable physiotherapists to refine their PA prescriptions, aligning short-term rehabilitative goals with the broader scope NCD management while fostering principles of healthy ageing.Method: Electronic searches were conducted in: PubMed, EBSCOhost (Academic Search Premier – Africa-Wide Information, CINAHL, Health Sources Premier), Scopus and Google-Scholar to identify peer-reviewed studies published after 2010 related to PA, ageing, NCDs and older people (OP) in sub-Saharan Africa.Results: A structured PA protocol, comprising aerobic activity at 60% – 79% of maximal heart rate and resistance training at 50% – 60% of one-repetition maximum (3 weekly sessions each), proved effective in reducing NCDs. Integrating lifestyle behaviour changes further enhanced outcomes, notably improving blood sugar management and cardiac health.Conclusion: Structured aerobic and resistance PA, combined with lifestyle education, significantly reduces NCD risk factors in older adults, supporting healthy ageing.Clinical implications: The current research base in the field of ageing in SSA is limited, indicating the need for non-pharmacological interventions to manage the prevalence of NCDs, including in mental/cognitive health, where PA has a direct influence.
