The >494 Ma Lillevik ophiolite fragment (Gratangseidet Igneous Complex) near Narvik, Scandinavian Caledonides

One of several irregular, plagioclase-phyric felsic veins in the Lillevik ophiolite fragment (Gratangseidet Igneous Complex) in Narvik, northern Norway, yielded a U–Pb zircon age of 494 ± 5 Ma. The veins cut deformed, compositionally layered, light REE-depleted gabbros that arguably constituted part of the now-dismembered ophiolite stratigraphy. The felsic veins were themselves deformed, probably during Silurian Scandian deformation, but the cross-cutting relationships suggest that they post-date initial deformation of the ophiolitic rocks. The felsic veins are strongly depleted in heavy REE and have moderately juvenile Lu–Hf zircon compositions, with εHf494 between 6.2 and 9.9. By analogy with felsic rocks in other Caledonian ophiolites and supported by cross-cutting relationships, the chemical and isotopic data can be interpreted to reflect formation by partial melting of basaltic rocks in the presence of residual garnet. In this case, the felsic veins probably post-date ophiolite formation and obduction onto a continental margin. We therefore interpret the age of 494 Ma to represent the minimum age of formation of the Lillevik ophiolite fragment. Previously published age, isotopic and chemical data from the region document an at least 20 Myr-long complex magmatic evolution following ophiolite obduction. The new data show that Late Cambrian to Early Ordovician ophiolite fragments extend along most of the length of the Scandinavian Caledonides. The tectonic significance of a previously published age of 474 Ma from the Gratangseidet Igneous Complex and 481 to 469 Ma ages from a tonalite sheet in the nearby Lyngen ophiolite, both interpreted to reflect ophiolite formation, needs to be tested by obtaining whole-rock geochemical data from these units. ablation cathodoluminescence LA–ICP–MS using ablation.

Game Streamers’ Practices on Twitch and Management of Well-Being

There has been a noticeable increase in coverage and academic research on the physical and psychological well-being of game streamers. Existing studies have identified challenges and possible negative effects to streamers’ well-being, and they have also explored how streamers utilize the technological features of streaming platforms in their streaming practices. However, scant research has investigated the links between the use of platform features and the management of well-being issues. This study examined how streamers use technological features, the negative well-being issues of streamers, and their coping strategies for these issues. Based on a qualitative content analysis of 23 hours of video interviews with 23 different game streamers discussing well-being issues related to streaming, findings indicate that challenges to well-being arise from prioritizing different outcomes in their streaming practices, and it is game streamers’ resilience and self-aware platform feature use that enables them to face these challenges.
Pomegranate (Punica granatum L.) peel powder meal supplementation in broilers: effect on growth performance, digestibility, carcase and organ weights, serum and some meat antioxidant enzyme biomarkers

Abstract This study determined the dietary effects of pomegranate peel powder meal (PPPM) supplementation on growth performance, digestibility, carcase and organ weights, serum, and some meat antioxidant enzyme indices of Cobb 500 birds. Birds (n = 432) were randomly assigned to six experimental groups of four replicates each and were fed either diets supplemented with 2, 4, 6 and 8 g/kg of PPPM (PPPM2, PPPM4, PPPM6 and PPPM8), 0% additives (Negative control; NEGCON), or with α-Tocopherol acetate at 200 g/tonne (Positive control; POSCON). The diet × week interaction effect on feed intake (FI) and feed conversion ratio (FCR) showed that the POSCON diet promoted a better FI and FCR at week 3. However, the FCR of the POSCON birds was comparable to that of the NEGCON, PPPM4 and PPPM6 birds. The average final body weight and average daily weight gain was highest in the PPPM2 and PPPM4 birds, whereas, PPPM2 birds had improved FCR and protein efficiency ratio compared with the POSCON birds. Thigh weight was highest in the PPPM4 group, whereas PPPM8 birds had the highest breast weight compared with the POSCON. Birds fed the PPPM4 diet also had improved nutrient digestibility compared with the POSCON birds. Spleen and gizzard weights were highest in PPPM4 birds compared with the NEGCON group. The concentration of serum aspartate aminotransferase (AST) was decreased in PPPM4 birds, whereas meat from PPPM8 group had the highest catalase enzyme activity. It can be concluded that birds fed 4 g/kg PPPM outperformed the birds that were fed α-tocopherol supplemented (POSCON) diets in terms of performance, digestibility, carcase and organ indices. The effect of pomegranate peel powder meal supplementation was also pronounced in decreasing the concentration of AST at 4 g/kg and increasing the activity of catalase enzyme at 8 g/kg compared with the POSCON and NEGCON diets. Highlights Dietary pomegranate peel powder can improve performance in broilers. Dietary pomegranate peel powder can enhance the enzyme activity of broiler meat.
PETROGRAPHY AND GEOCHEMISTRY OF METASEDIMENTARY ROCKS FROM THE TAKU SCHIST IN KELANTAN, NORTH-EAST PENINSULAR MALAYSIA.

The Taku Schist, which is located in the north-east Peninsular Malaysia, is characterized by its North-South oriented elongated body. It forms part of the Indonesian orogenic build-up that was generated via the convergence of the Sibumasu continental unit and Sukhothai Arc. Subsequent petrography analyses of the metasedimentary rocks sourced from the Taku Schist revealed that their formation was attributable to the metamorphism of greenschist into amphibolite facies, which could be observed near the Triassic and Cretaceous intrusions of the Kemahang Granite. The evolutionary process of the rocks could be linked with the interactions occurring between contact and regional metamorphisms. The resulting chemical classification upon their assessment disclosed that the metasedimentary rocks of Taku Schist were made up of greywacke and shale, grouped into the quartzose sedimentary provenance, and belonged to the Continental Island Arc (CIA). This information is required for the tectonic setting discrimination purpose. It is a reflection of the episodic contractions underwent by the Taku Schist, wherein they would lead to the Sibumasu sedimentary cover along with both an accretionary wedge and the genetically-correlated Bentong-Raub melange to different greenschist. Otherwise associated with amphibolite facies, the conditions and depths of the facies were determined according to their position in relation to the upper plate of the Sukhothai Arc.
Can Climate and Environmental Factors Putatively Increase SARS-Cov2 Transmission Risks?

After the identification of the first SARS-COV-2 infected cases in China, the virus was rapidly disseminated among the distinct continents and the COVID-19 pandemics was announced by the WHO in March 2020. Over time, the epidemiological sceneries varied among countries, according to the adopted mitigation measures and epidemic phase. Recently, a recrudescence of the epidemics has been observed in distinct countries. SARSCoV-2 can be transmitted by direct or indirect contact. The viral RNA has been detected in stool and other clinical specimens from infected patients and a putative fecal-oral transmission has been argued. Viruses are shed in human excreta, further disposed into the sewerage system or into the environment, in poor sanitation settings. Thus, SARS-CoV-2 RNA has been regularly detected in wastewater and surface water impacted by the direct discharge of sewage. Some studies have reported an association between climatic parameters and an increase in COVID-19 incidence. However, conclusive evidence based in full seasons is needed so far. This mini-review briefly discusses the putative role of climate and environmental factors on SARS-CoV-2 exposure, transmission and circulation patterns. Moreover, some additional challenges in middle and low-income settings are highlighted. Efforts must be driven to categorically understand the relationships between SARS-CoV-2 infection, circulation patterns and climate parameters, as the putative implications of viral persistence and viability in distinct environmental matrices. This information is crucial for COVID-19 control and prevention, especially in middle and low-income settings, already wedged by social inequality, inadequate sanitation and deficient healthcare admission.
Educational Experiences of Care Leavers from Residential Care in Ghana

Abstract The study aims to explore the experiences of Ghanaian care leavers to discern the factors that promote and impede their educational attainment. Data was collected from 23 care leavers using semi-structured interviews. The interviews were then analyzed using the framework method. The findings suggest that the personal motivation of the care leavers and encouragement from significant adults and peers facilitated their academic success. However, the participants identified stigma, lack of academic support, and the inability to participate in decisions as barriers to their education. Recommendations include training residential care staff to enable them to facilitate the participation of young people in decisions about their education, encouraging and supporting young people in care to aspire for higher education, and developing plans to guide their educational progress.
Can social media-based brand communities build brand relationships? Examining the effect of community engagement on brand love

ABSTRACT The rise of social media has dramatically changed relationship building between brands and fans. Social media-based brand communities are widely embraced by firms who use them to create consumer engagement and facilitate stronger consumer-brand relationships. Despite the importance of consumer engagement, our understanding of what drives community engagement and how individuals' love for a brand can be facilitated through SMBBCs remains limited. Based on social identity theory and social capital theory, this study explores the aforementioned gap by proposing an integrated conceptual model that encompasses the individual and group-level factors contributing to the establishment of community engagement, which in turn facilitates an individual's love for a brand and ultimately leads to positive behaviours towards the brand. We conducted a survey and found that community engagement, which is driven by brand identification and social capital (relational, structural, and cognitive capital), is a key determinant facilitating an individual's love for a brand. This love subsequently affects the individual's inclination to engage in brand-related information-sharing behaviours. The results of this research can guide practitioners in designing a SMBBCs by using relationship-building activities.
Good news for whom? The Pfizer/BioNTech vaccine announcement reduced political trust

The announcement of Pfizer/BioNTech’s COVID-19 vaccine success on 9 November 2020 led to a global stock market surge. But how did the general public respond to such good news? We report results of a nation-wide natural experiment in the US and the UK on how the vaccine news influenced citizens' government evaluations, anxiety, beliefs and elicited behaviors. While most outcomes were unaffected by the news, trust in government and elected politicians (and their competency) saw a significant decline in both countries. As the news did not concern the government, and the government did not have time to act on the news, our results suggest a dispositional response to positive news more likely to be explained by a form of the psychological mechanism of motivated reasoning. They also offer a novel insight regarding the association between trust in government and compliance with its policies: anxiety might explain both.
Spatial and temporal variability in geomorphic change at tidally influenced shipwreck sites: The use of time‐lapse multibeam data for the assessment of site formation processes

Shipwrecks are an integral part of our maritime archaeological landscape and are associated with diverse societal and cultural interests, yielding significant management challenges. Coupled hydrodynamic and geomorphological processes significantly impact the effective in situ preservation of these fragile sites. In this study, we assess sediment budget change and hydrodynamic triggers at metal‐hulled shipwrecks lost between 1875 and 1918, all located in the tidally dominated Irish Sea at depths between 26 and 84 m. This is conducted using time‐lapse, multibeam echosounder surveys at multiannual, annual, and weekly time steps, supported by sediment grain‐size analysis, modeled ocean currents, and shallow seismic data. Results indicate significant changes at all time steps for sites located in sand‐dominated environments, whereas the seabed around shipwrecks settled in multimodal sediments shows virtually no change outside of measurement errors (±30 cm). Variability in geomorphic change is attributed to local environmental factors, including bed shear stress, sediment supply, and spatial barriers to scour. We demonstrate that individual wrecks in similar shelf sea regions can be in very different equilibrium states, which has critical implications for the in situ management of underwater cultural heritage.
Observed and projected changes in global climate zones based on Köppen climate classification

In recent years, there has been a growing body of literature applying the Köppen classification scheme to investigate the changes in the distribution of bioclimatic conditions. Area changes and latitude and elevation shifts of Köppen climate zones have been examined based on the observed and projected datasets. This review article provides a comprehensive insight into the changes in global Köppen climate zones. First, we summarize the advancements and limitations of different climate zone definitions and assess the available climate classification map products. We then review recent detection and assessment studies on observed and projected climate zone changes. Finally, we summarize the findings of the previous studies. It has been proven that changes in climate zones under global warming can have far‐reaching impacts on ecological systems. Since the 1980s, anthropogenic accelerated global warming has already led to shifts in climatic conditions over a large land area. Hot tropics and arid climates are projected to expand into large areas of middle and high latitudes, an expansion that is potentially linked to the intensification of the global hydrologic cycle. Driven by increased warming in the Arctic, high‐latitude climates will shift poleward and upward, leading to a significant area shrinkage of the polar climate zones. However, due to the large model uncertainties, the detectability of significant climate zone changes through observations and projections, the rate and time of the changes, and their causes remain unclear. In this paper, we identify the research gaps and propose directions for future research.

Introduction : The administration of antioxidant combination has been shown to be more effective than that of individual antioxidant in male infertility. Objective : to determine the effect of different combination of antioxidants (vitamin/vit C, vit E, glutathione and zinc) on the number of Sertoli and Leydig cells, sperm quality and texpression of caspase-3 in rats exposed to cigarette smoke. Methods : This was an experimental study using a post test only control group design. Thirty six rats were randomly divided into 6 groups to receive one of the following combinations of antioxidants: vit C and E, glutathione, zinc (T4-G); vit C and E, glutathione (T3-G); vit C and vit E (T2-G); Glutathione, zinc (T1-G); control positive (CP-G) cigarette smoke exposed only, normal (CN-G). The dose of vit C, vit E, glutathion and zinc was 9 mg/day, 1.8 IU/day, 1.8 mg/day, 0.2 mg/day respectively. All groups were exposed to cigarette smoke (3 cigarettes/day for 21 days), except for the CN-G group. On day 22, sperm samples were taken. Testicular tissue was taken for measurements of sperm quality, sertoli and leydig cell.numbers. Results : There was a significant difference in mean number of Leydig cells, sperm motility, sperm count and caspase-3 between groups (p<0.05). Post hoc LSD showed that the administration of combination of four antioxidant agent increasing the number of Sertoli cells and sperm morphology. The results also showed that group treated with 4 antioxidants combination had the highest number of Leydig cells, sperm motility, sperm counts and the lowest expression of caspase-3. Conclusion :The combination of vitC, vit E, glutathione and zinc affects the number of Sertoli and Leydig cells, sperm quality, expression of caspase-3 in rats exposed to cigarette smoke .
On the drivers of successful crowdfunding: The case of the platform Verkami

This article analyzes the determinants of successful crowdfunding initiatives using a sample of 5,251 projects from the reward-based Spanish platform Verkami. In contrast to most of the literature that has measured success with a dichotomous variable, we approach success with a continuous one, namely the ratio of achievement, which is measured as the obtained resources over the total amount requested by the promoter. We consider a set of potential determinants of success, which are theoretically well-grounded and cover a variety of spheres related to project features. Results suggest that factors related to the signaling theories such as partnership, having previous experience and interaction with backers are positively associated with the achievement ratio, whereas no significant impact is found for the number of rewards. In addition, we find uneven effects for low and high ratios of achievement, identifying the key determinants in different project stages. JEL CLASSIFICATION D26; G29; L26; L86; M13; M21
Evaluation of Human Epidermal Growth Factor Receptor 2 Overexpression, Clinicopathological Characteristics, and Factors Affecting Survival in Gastric Cancer

Objectives: The objective of the study was to evaluate the human epidermal growth factor receptor 2 (HER2) overexpression, clinicopathological features, and factors affecting survival in patients with gastric cancer. Methods: The study is a retrospective study conducted with 128 cases of gastric cancer who were admitted to Şişli Hamidiye Etfal Training and Research Hospital between 2005 and 2012. Patients’ demographic characteristics, performance score, tumor localization, information about surgery, HER2 measurements, histopathological characteristics, stage, treatment features, metastasis sites, and overall survival time were obtained from medical records. Immunohistochemical analysis was performed for HER2 scoring. Results: There were 89 (69.5%) men and 39 (30.5%) women in the study group, and the median age of the patients was 64 years. The median survival time of the patients was 24.43 months. The survival rate of the patients was calculated as 35.4±5.9%. Overall survival time was found to be shorter in the group with higher HER2 levels and also those with advanced-stage cancer. The survival rate was found to be significantly lower in patients with perineural invasion and advanced stage. However, the survival rate was not associated with lymphovascular invasion, surgical margin involvement, and HER2 levels. In the multivariate Cox Regression analysis performed to assess the effects of gender, histological subtype, stage, and surgical margin on overall survival, disease stage was found to be the only factor effective on survival. Gender, histological subtype, and the surgical margin did not affect prognosis. Conclusion: The survival rate in gastric cancers was found to be lower in those with advanced-stage disease. Higher HER2 level and the disease stage were associated with shorter overall survival time.
Disability and Self-Advocacy Experiences in University Learning Contexts

Disabled students in Canadian universities are usually taught that they must develop the ability to discuss their disabilities and assert their rights if they want to achieve academic success. Yet this individualized skills-based approach can privilege deficit-focused methods and impose hierarchical and mutually anxiety-provoking student-faculty relationships. This study documents the experiences of disabled students and their professors arranging academic accommodations by exploring the relational necessities of student self-advocacy and how they shape experiences of teaching and learning at three Nova Scotia Universities. Findings expose the existence of formal self-advocacy teaching alongside informally communicated behavioural expectations. They also make evident the often unrecognized relational complexities inherent in claiming disability rights, navigating university process, and meeting expectations around student sharing of disability and accommodation information.
