Published: March 2022

Вступ. Важкі метали – група ксенобіотиків, які мають найбільшу стійкість у навколишньому сере­довищі, та політропні токсини для людства. В основі дії важких металів лежить блокування функціонально активних груп структурних протеїнів, протеїнів-ензимів, найбільше значення має блокування сульфгідрильних (тіольних, SH) груп. За дії важких металів більшість протеїнів втрачає свої фізико-хімічні та біологічні властивості, що призводить до порушення протеїнового й іншого обміну речовин.
Мета дослідження – вивчити вплив Плюмбуму ацетату, Купруму сульфату і гліфосату (в формі гербіциду раундапу) та коригувальну дію цистеїл-гістидил-тирозил-гістидил-ізолейцину на зміни показників ендогенної інтоксикації і стан мембран у щурів різного віку.
Методи дослідження. Досліди проводили на лабораторних нелінійних білих щурах-самцях 3 вікових періодів (статевонезрілих, статевозрілих і старих), яким внутрішньошлунково впродовж 30 днів вводили водні розчини Плюмбуму ацетату, Купруму сульфату і гліфосату (в формі раундапу). З метою корекції на 21-й день через 6 год після введення токсикантів упродовж 10 днів вводили пептид (цистеїл-гістидил-тирозил-гістидил-ізолейцин). У сироватці крові уражених та коригованих щурів визначали активність аланінамінотрансферази (АлАТ, КФ 2.6.1.2), аспартатамінотрансферази (АсАТ, КФ 2.6.1.1) та вміст молекул середньої маси (MСM).
Результати й обговорення. Як показали наші дослідження, введення Плюмбуму ацетату, Купруму сульфату і гліфосату призводило до зміни показників білкового обміну в тварин різного віку. Ці токсиканти збільшували вміст МСМ та активність амінотрансфераз у плазмі крові уражених щурів. За дії Плюмбуму ацетату, Купруму сульфату і гліфосату та їх поєднання cпостерігали підвищення активності амінотрансфераз у сироватці крові тварин. Найбільш виражене зростання активності цих ензимів відзначали у щурів 3-місячного віку. Таким чином, активність ензиму АлАТ була вищою на 164 % при ураженні Купруму сульфатом, на 184 % – Плюмбуму ацетатом, на 276 % – гліфосатом, на 428 % – за їх комбінованого ураження порівняно з контролем (інтактні тварини). Активність ензиму АсАТ змінювалася так само, як і активність АлАТ. Вона зросла у 2,6; 2,7; 2,1 раза у сироватці крові 3-, 6- та 24-місячних тварин із комбінованим ураженням (р<0,05) відповідно.
Висновки. За 30-денної токсичної дії Плюмбуму ацетату, Купруму сульфату і гліфосату (в формі раундапу) в дозі 1/20 LD50 пригнічуються функції печінки. Підвищення вмісту МСМ та активності амінотрансфераз (АлАТ, АсАТ) у сироватці крові вказує на синдром токсичного гепатиту. Введення пептиду (цистеїл-гістидил-тирозил-гістидил-ізолейцину) як коригувального чинника щурам різного віку з токсичним ураженням печінки знижує ензимну активність амінотрансфераз та вміст молекул середньої маси.
S-ProvFlow. Storing and Exploring Lineage Data as a
Service
Authors: Spinuso Alessandro , Atkinson Malcolm , Magnoni Federica 
Published: March 2022

Abstract
We present a set of configurable Web service and interactive tools, s-ProvFlow, for managing and exploiting records tracking data lineage during workflow runs. It facilitates detailed analysis of single executions. It helps users manage complex tasks by exposing the relationships between data, people, equipment and workflow runs intended to combine productively. Its logical model extends the PROV standard to precisely record parallel data-streaming applications. Its metadata handling encourages users to capture the application context by specifying how application attributes, often using standard vocabularies, should be added. These metadata records immediately help productivity as the interactive tools support their use in selection and bulk operations. Users rapidly appreciate the power of the encoded semantics as they reap the benefits. This improves the quality of provenance for users and management. Which in turn facilitates analysis of collections of runs, enabling users to manage results and validate procedures. It fosters reuse of data and methods and facilitates diagnostic investigations and optimisations. We present S-ProvFlow's use by scientists, research engineers and managers as part of the DARE hyper-platform as they create, validate and use their data-driven scientific workflows.
From a Dynamic Image Annotation Process within the Humanities to a Canonical Workflow

Published: March 2022

Abstract
One idea of the Canonical Workflow Framework for Research (CWFR) is to improve the reusability and automation in research. In this paper, we aim to deliver a concrete view on the application of CWFRs to a use case of the arts and humanities to enrich further discussions on the practical realization of canonical workflows and the benefits that come with it. This use case involves context dependent data transformation and feature extraction, ingests into multiple repositories as well as a “human-in-the-loop” workflow step, which introduces a certain complexity into the mapping to a canonical workflow.
In Between Hogging and Passing the Mic; Or, the Unintended Consequences of Networked Radio in Ghana
Authors: Nikoi Nii Kotei , Avle Seyram 
Published: March 2022

Abstract
This paper explores the relationship between networked radio, media participation, and accountability in Ghana. Specifically, we examine how networked radio, the hybrid media space that is the convergence of radio and social media practices, works as a means of democratic accountability through citizen participation in media. We do this through an analysis of how two English-speaking radio stations in Ghana act as intermediaries between citizens and the state, underscoring how the networked elements of radio production facilitate public discourse and make the state less opaque to citizens. We show that while networked radio does provide multiple opportunities for media participation, this participation is relatively passive for the majority of listeners, in part because producers face increased interactivity in-studio and must employ gate-keeping tactics to fit the constraints of airtime. This trade-off inadvertently privileges elite voices over others, even if the radio stations work to diversify the voices heard on air. Still, networked radio provides a limited but necessary alternative to exacting accountability from public officials as those very dynamics of participation elicit the state’s responsiveness more regularly than the formal routes established for those purposes. Accordingly, we characterize Ghanaian networked radio as caught between ‘hogging the mic’ for an elite group of listeners and ‘passing the mic’ between them, the state, and the broader citizenry that constitute the listening public.
Diversity, Multilingualism and Democratic Practices in Nepal
Authors: Gautam Bhim Lal , Poudel Prem Prasad 
Published: March 2022

Abstract
This paper presents the relationship among Nepal’s linguistic diversity, multilingualism, and democratic practices by bringing into ideas from the global north and global south. The guiding question for exploring this relationship is, “why is Nepal’s linguistic diversity being squeezed despite the formulation of democratic and inclusive language policies that intended to promote multilingualism?”. To investigate this concern, qualitative data were obtained from semi-structured interviews with two purposively selected high-profile people working in the capacity of language policymaking in the state agencies. In Nepal, although democracy promoted awareness towards the issue of language rights and the need of preservation and promotion of minority languages, the narrowing of multilingual diversity continued in practice. This study concluded that democracy allowed neoliberal ideologies to penetrate sociolinguistic spaces and put greater emphasis on English and Nepali. While there is an intertwined relationship between linguistic diversity, democracy, and multilingualism, the ongoing democratic practices have become counterproductive in maintaining the linguistic diversity leading to the marginalization of minority and lesser-known languages. Also, despite ample literature documenting linguistic diversity as a resource and opportunity, the notions of ‘linguistic diversity’ and ‘multilingualism’ were utilized merely as political agendas and issues of critical discourses which have left negligible impact on changing the conventionalized practices of linguistic domination of Nepali and English. Therefore, we question the co-existence of diversity and democracy and claim that democracy alone does not necessarily contribute to the protection of linguistic diversity. In line with this concept, democratic practices could even be counterproductive in the promotion and protection of linguistic diversity. Our findings suggest future interventions about essentializing the use of minority languages in education and governance, alongside democracy providing the fertile grounds for policy pitches to address micro problems in maintaining multilingualism within a democracy.
Just Enough English to Get by: Language Practices of Transnational Migrants in Chinese Stores in Cape Town, South Africa
Authors: Thompson Miché 
Published: March 2022

Abstract
The presence of a Chinese community in South Africa has become increasingly visible over the last decade, particularly in the trading sector. This is illustrated in the sizable number of new shopping centres settled specifically by groups of Chinese traders, known as China Towns. Shopkeepers and shop assistants come from various linguistic and cultural backgrounds, China and other African countries respectively, but living and working in a multilingual South Africa, they communicate in English, which is the lingua franca. This paper explores their language practices and reflects on a particular language contact situation where shopkeepers and assistants of various migrant origins work closely together. The study adopts a linguistic ethnographic approach to the analysis of the interaction between shopkeepers and assistants and uses conversation analysis to elucidate the ways in which meaning is negotiated and understood in interaction between multilingual speakers. Unscripted audio recorded spoken interaction of the participants throughout the workday is the primary source of data. Additionally, interviews and observational notes are used to supplement the interactional data and illustrate the creative forms of language use that emerge in a in a China Town centre near Cape Town in the Western Cape.
The Power of the Periphery: Circulation of Cross-Cultured Languaging Through the Importation of Francophone Comics in the Nation-State of Sweden, 1900–2020
Authors: Lindberg Ylva 
Published: March 2022

Abstract
The objective with this study is to shed light upon how international exchanges on the comic art market contribute to democratization processes and renegotiation of hegemonies in the literary field worldwide. The focus is on how the variation in imported comics from a central language, in this case French, to the peripheral space of Sweden, can be observed during the time-period 1900–2020, as well as on which diversity importation of comics has been allowed over time. Theoretically anchored in sociological perspectives in literary studies highly influenced by Casanova’s ([1999]2004) seminal work, this contribution challenges established approaches in the field that depart from central cultural spaces in the world. Instead, this analysis highlights how the periphery gains agency on the international market and challenges relations of domination through translation practices. One hypothesis put forward consists of the idea that Francophone author-illustrators from the global South would be identifiable in the data in 1990’s, as is the case in the literary field. However, in the comics field this change emerges later, and does not appear distinctively until 2005. The change is paired with a promotion of Francophone female author-illustrators in Swedish translations, equally from the global South and the global North. The results also highlight that Sweden positions the Francophone space as hyper-central within the comics field. The specific practices adopted in the importation point to how a periphery creates agency to define a medium and a genre locally and play a role in international cultural exchanges.
Re-considering orientations in South African Language Policies
Authors: van der Merwe Chanel 
Published: March 2022

Abstract
What should be taken into account when language policies are developed? It is rarely the case that when language policies are developed, the focus is on issues outside of ‘language’. However, when issues of language are experienced in certain societies as a “cumulative disadvantage” (Piller 2016) together with other forms of domination, normative conceptualisations of language policy seem inadequate. The notion of ‘inhabitance’ is a generative lens through which to illustrate this. In the South African university space, since the #MustFall protests, the question of ‘inhabitance’ has taken centre stage in issues of curriculum and access. Through the act of throwing poo on the statue of Cecil John Rhodes, the #MustFall protests have firmly put on the agenda the need for universities to reflect upon itself, and to ask whose knowledges, bodies, histories and lifeworlds it legitimizes, and therefore, its complicity in maintaining coloniality. This has led to a wider call to decolonize universities. However, while the notion of ‘inhabitance’ has been central to the #MustFall protests, it has not been considered from the position of language and language policy. This paper reflects on institution-wide language policy conversations at a South African university arguing to shift attention from the orientations we take to language in language policy, to how policies “orient” (Ahmed 2007) bodies in university spaces. This paper seeks to add to the conversation in the South African Higher Education space in anticipation of the implementation of the new Language Policy for Higher Education (2020).
Sociolinguistic Protests for Decolonial Future Making: Toward Centering Languaging in the “Streets”
Authors: Lee Eunjeong , Makoni Sinfree 
Published: March 2022

Abstract
In scholarly discussions on “language” and “diversity,” much critique has been offered as to how research on languaging is implicated in perpetuating coloniality and pursuing decolonial options, including the white-gaze understanding and approach to the term, “diversity” (Heller and McElhinny 2017; Mignolo 2009; Rosa and Flores 2017; Walcott 2018). Extending these discussions, this article calls for centering languaging in the “streets” as an important way for sociolinguistics to contribute to building decolonial futures. We see “streets” as an embodied, dynamic space, organized by the goal of decolonial future making, layered with conflicting struggles, discourses, and historicities. Examining languaging in the “streets” can highlight how those oppressed by various colonial conceptualizations and ongoing coloniality work toward social justice and transformation in and beyond classrooms. We suggest three important considerations in sociolinguistic research on languaging in the “streets,” and conclude by emphasizing the importance of reflexivity of individual researchers and the field as a whole.
Interdecadal Variation of the Number of Days with Drought in China Based on the Standardized Precipitation Evapotranspiration Index (SPEI)
Authors: Wang Zunya , Zhang Qiang , Sun Shao , Wang Pengling 
Published: March 2022

Abstract
Based on the standardized precipitation evapotranspiration index (SPEI), a significant increase after the mid-1990s is detected in the annual number of days with drought in the zonal belt from southern Xinjiang to southern Northeast China and North China. This change features the predominant mode of the annual number of days with drought in China. Meanwhile, two significant breakpoints in 1981 and 2001 indicate a continuous increase of days with drought in the meridional belt from eastern Northwest China to eastern Southwest China. The increase in days with drought is closely related to the significant warming in the zonal belt but is attributed to both the increase of temperature and the decrease of precipitation in the meridional belt. The typical circulation patterns responsible for the increase of days with drought comprise a wave train stretching from North Atlantic to East Asia, the generally anomalous high pressure over China, the northerly anomalies prevailing over northern and central China, and the suppressed convection in most of the zonal and meridional belt. Both the AMO and the PDO after the 1980s have a close relationship with the interdecadal variation of the number of days with drought. On one hand, either a positive AMO phase or negative PDO phase motivates the typical circulation patterns favorable for the occurrence of drought. On the other hand, both the AMO and PDO affect the warming in the zonal and meridional belt, and the PDO is also closely connected with the precipitation in the meridional belt.

Published: March 2022

Objective: The purpose of this study was to investigate Japanese undergraduate students’ learning experiences as part of an online sexuality education workshop. Design: We employed a qualitative design using in-depth, semi-structured interviews. Setting: The study was conducted at a public university in the Kanto region of Japan. Method: Interviews elicited seven Japanese undergraduate students’ perspectives concerning the format of the online sexuality education course and beliefs about sexual health and behaviours. Interviews were analysed using the constant comparative method. Results: Three themes were identifiable in informants’ responses: (1) benefits of the online education format, (2) importance of sexuality education for students who live alone and (3) learning about abortion. Students’ learning experiences were influenced and shaped by online communication through the sharing of knowledge regarding sexuality, sexual security and sexual health. Conclusion: Although learning took place in a 1-day workshop, there were significant benefits to offering an online sexuality education workshop to Japanese undergraduate students.
Students’ Fear of Missing Out Predicts In-Class Social Media Use
Authors: Shane-Simpson Christina , Bakken Tatiana 
Published: March 2022

Background College students frequently identify social media sites (SMSs) as in-class distractions, although students continue to use these sites during class. In a technology-driven world, students’ fear of missing out (FOMO) may drive SMS behaviors, whereby classes and study time serve as obstacles to fulfilling one’s social desires. Objective The current study investigated whether students’ use of SMSs during class and study time was predicted by demographic characteristics and students’ FOMO. Method Participants ( N = 198) completed an online survey assessing their media use during class and study time, FOMO, and their perceived advantages/disadvantages of media use. Results In-class Twitter and Instagram use were predicted by students’ FOMO, whereas Snapchat and Facebook use were only predicted by age. Age also predicted Snapchat use during study time. Most participants indicated that media was a distraction, while also reporting a range of benefits from media multitasking. Conclusion Given that students recognize both benefits and drawbacks of media multitasking, they may trade-off between their desire to engage with learning materials and their desire to stay socially connected with others. Teaching Implications Educators can begin to address the socio-emotional needs of students through modifications made to course design and student-centered learning materials.
