Non-invasive brain stimulation as add-on therapy for subacute post-stroke aphasia: a randomized trial (NORTHSTAR)

Introduction Non-invasive brain stimulation (NIBS) with speech therapy might improve recovery from post-stroke aphasia. This three-armed sham-controlled blinded prospective proof-of-concept study tested 1 Hz subthreshold repetitive transcranial magnetic stimulation (rTMS) and 2-mA cathodal transcranial direct current stimulation (ctDCS) on the right pars triangularis in subacute post-stroke aphasia. Patients and methods Sixty-three patients with left middle cerebral artery infarcts were recruited in five hospitals (Canada/United States/Germany, 01–2014/03–2018) and randomized to receive rTMS (N = 20), ctDCS (N = 24) or sham stimulation (N = 19) with ST for 10 days. Primary outcome variables were Z-score changes in naming, semantic fluency and comprehension tests and adverse event frequency. Secondary outcome variable was the percent change in the Unified Aphasia Score. Intention-to-treat analyses tested between-group effects at days 1 and 30 post-treatment with a pre-planned subgroup analysis for lesion location (affecting Broca’s area or not). Results Naming was significantly improved by rTMS (median = 1.91/interquartile range = 0.77/p = .01) at 30 days versus ctDCS (median = 1.11/interquartile range = 1.51) and sham stimulation (median = 1.02/interquartile range = 1.71). All other primary results were non-significant. The rTMS effect was driven by the patient subgroup with intact Broca’s area where NIBS tended to improve UnAS (median = 33.2%/interquartile range = 46.7%/p = .062) versus sham stimulation (median = 12.5%/interquartile range = 7.9%) at day 30. Conversely, in patients with infarcted Broca’s area, UnAS tended to improve more with sham stimulation (median = 75.0%/interquartile range = 86.9%/p = .053) versus NIBS (median = 12.7%/interquartile range = 31.7). Conclusion: We found a delayed positive effect of low-frequency rTMS targeting the right pars triangularis on the recovery of naming performance in subacute post-stroke aphasia. This intervention may be beneficial only in patients with morphologically intact Broca’s area.
Influence of Ag Addition on Thermal Stability and Thermophysical Properties of Ti-Zr-Ni Quasicrystals

We study the effects of Ag addition on thermal stability and thermophysical properties of Ti-Zr-Ni icosahedral quasicrystals. The Ag addition results in increasing the coherence length and thermal stability of the icosahedral phase (i-phase) of the as-cast Ti35.2Zr43. 8Ni21 alloy, which are maximized at around 4 at. % Ag addition. Differential scanning calorimetry (DSC) and electrostatic levitation (ESL) experiments reveal that the addition suppresses the i-phase decomposition on heating and cooling. We find that considerable amount of the i-phase remains in the samples processed by radiational cooling in ESL as the Ag concentration increases. These results demonstrate that Ag addition stabilizes the i-phase of the Ti35.2Zr43. 8Ni21 alloy. No anomalous effect of Ag addition is found on density and viscosity of the Ti35.2Zr43. 8Ni21 liquid.
Sustainable Financial Products in the Latin America Banking Industry: Current Status and Insights

The purpose of this study is to analyse the extant literature on sustainable financial products (SFP) with a comprehensive understanding of the status quo and research trends as well as characterise the existing SFP in the Latin America banking industry. In this way, research papers derived from Scopus as well as institutional reports such as main documents, sustainability reports, and product portfolios publicly available on webpages from public, private, and development banks are used to create a database of SFP where their main characteristics are included and classified. Based on the research trends identified, the results show the development of financial products focused on environmental, social, and government (ESG) matters, mainly from the credit side, of more sustainable financial markets and products under fintech ecosystems. The results show that because of regulatory and government support through mechanisms such as green protocols and social and environmental responsibility policies, private financial institutions of Brazil, Colombia, and Argentina have led the development of both social and green financial products. These study’s findings may be used for several policymakers to broaden the opportunities available in sustainable financing and thus, provide a roadmap that researchers and practicing professionals can use to improve their understanding of SFP. Finally, the study presents the potential for further research in the field, both with a qualitative and a quantitative approach.
Green Sonochemical Synthesis of Silver Nanoparticles Using Adansonia Digitata Leaves Extract and Evaluation of Their Antibacterial Potential

Metal nanoparticles in the field of nanotechnology are of great interest to modern scientific research due to their size effects, medical uses and, catalytic, electronic and optical properties. Green synthesis of metal nanoparticles is a feasible alternative to chemical methods as it is environmentally friendly and cost effective. In continuation with our research on green synthesis of silver nanoparticles using Kenyan medicinal plants, we here report the synthesis of novel silver nanoparticles (AgNPs) on ultrasonic bath using Adansonia digitata leaves extracts and analysis of their antibacterial activity. The nanoparticles were characterized by UV-Vis, High Resolution Transmission Electron Microscopy (HRTEM), FTIR spectroscopy and Energy Dispersive X-ray (EDX). EDX analysis affirmed the nanoparticles were pure silver. Crystalline nature of the nanoparticles was confirmed by bright circular spots in the Selected Area Electron Diffraction (SAED) in HRTEM image. The AgNPs were spherical with an average size 13 nm. FTIR analysis showed strong –C=C- and –OH stretching bands due to compounds capping the nanoparticles. The synthesized AgNPs showed high inhibition zones of 17.1±0.130 mm towards Gram-negative bacteria E. coli and 12.9±0.082mm towards Gram positive bacteria S. aureus. The aqueous A. digitata extract had no effect on growth inhibition of test bacteria. The study showed that the silver nanoparticles synthesized from the plant’s leaves extract had antibacterial activity against both Gram negative and positive pathogenic bacteria. The nanoparticles can be utilized towards developing novel drugs useful in combating pathogens.
Asylum-Related Migrants’ Social-Media Use, Mobility Decisions, and Resilience

Abstract The article examines asylum-related migrants’ social-media use along their asylum journeys. In total, 2,454 migrants from 37 countries answered a semistructured survey conducted in Jordan; Turkey; Iran; and in the European “hotspots,” Lesvos, Greece, and Lampedusa, Italy. Of the respondents, 83% used at least one social-media service in their current locations, 55% acknowledged that social media makes their asylum-related life easier, and 51% responded that social media helped them decide where to move to in Europe. Migrants’ socioeconomic and demographic differences, social capital, and future views explain their social-media use in relation to their mobility decisions and resilience.
Phylogenomic analysis of Calyptratae: resolving the phylogenetic relationships within a major radiation of Diptera

The Calyptratae, one of the most species‐rich fly clades, only originated and diversified after the Cretaceous–Palaeogene extinction event and yet exhibit high species diversity and a diverse array of life history strategies including predation, phytophagy, saprophagy, haematophagy and parasitism. We present the first phylogenomic analysis of calyptrate relationships. The analysis is based on 40 species representing all calyptrate families and on nucleotide and amino acid data for 1456 single‐copy protein‐coding genes obtained from shotgun sequencing of transcriptomes. Topologies are overall well resolved, robust and largely congruent across trees obtained with different approaches (maximum parsimony, maximum likelihood, coalescent‐based species tree, four‐cluster likelihood mapping). Many nodes have 100% bootstrap and jackknife support, but the true support varies by more than one order of magnitude [Bremer support from 3 to 3427; random addition concatenation analysis (RADICAL) gene concatenation size from 10 to 1456]. Analyses of a Dayhoff‐6 recoded amino acid dataset also support the robustness of many clades. The backbone topology Hippoboscoidea+(Fanniidae+(Muscidae+((Anthomyiidae–Scathophagidae)+Oestroidea))) is strongly supported and most families are monophyletic (exceptions: Anthomyiidae and Calliphoridae). The monotypic Ulurumyiidae is either alone or together with Mesembrinellidae as the sister group to the rest of Oestroidea. The Sarcophagidae are sister to Mystacinobiidae+Oestridae. Polleniinae emerge as sister group to Tachinidae and the monophyly of the clade Calliphorinae+Luciliinae is well supported, but the phylogenomic data cannot confidently place the remaining blowfly subfamilies (Helicoboscinae, Ameniinae, Chrysomyinae). Compared to hypotheses from the Sanger sequencing era, many clades within the muscoid grade are congruent but now have much higher support. Within much of Oestroidea, Sanger era and phylogenomic data struggle equally with regard to finding well‐supported hypotheses.
Axisymmetric Natural Convection of Liquid Metal in an Annular Enclosure under the Influence of Azimuthal Magnetic Field

Natural convection of liquid metal in an annular enclosure under the influence of azimuthal static magnetic field was numerically studied. The liquid metal in the enclosure whose cross-sectional area is square was heated from an inner vertical wall and cooled from an outer vertical wall both isothermally whereas the other two horizontal walls were assumed to be adiabatic. The static azimuthal magnetic field was imposed by a long straight electric coil that was located at the central axis of the annular enclosure. The computations were carried out for the Prandtl number 0.025, the Rayleigh number 104, 5 × 105 and 107, and the Hartmann number 0–100,000 by using an in-house code. It was found that the contour map of the electric potential was similar to that of the Stokes stream function of the velocity regardless of the Hartmann number. Likewise, the contour map of the pressure was similar to the Stokes stream function of the electric current density in the case of the high Hartmann number. The average Nusselt number was decreased in proportion to the square of the Hartmann number in the high Hartmann number regime.
Evaluating the Data Quality of a National Sample of Young Sexual and Gender Minorities Recruited Using Social Media: The Influence of Different Design Formats

Social media recruitment is no longer an uncharted avenue for survey research. The results thus far provide evidence of an engaging means of recruiting hard-to-reach populations. Questions remain, however, regarding whether the data collected using this method of recruitment produce quality data. This article assesses one aspect that may influence the quality of data gathered through nonprobability sampling using social media advertisements for a hard-to-reach sexual and gender minority youth population: recruitment design formats. The data come from the Survey of Today’s Adolescent Relationships and Transitions, which used a variety of forms of advertisements as survey recruitment tools on Facebook, Instagram, and Snapchat. Results demonstrate that design decisions such as the format of the advertisement (e.g., video or static) and the use of eligibility language on the advertisements impact the quality of the data as measured by break-off rates and the use of nonsubstantive responses. Additionally, the type of device used affected the measures of data quality.
The Relationship among Product Risk, Perceived Satisfaction and Purchase Intentions for Online Shopping

This research investigates the relationship among product risk, financial risk, security risk, privacy risk, perceived satisfaction, and purchase intention. Validated measurements were identified from a literature review. The measurement model and the conceptual model depicting hypothesized relationships were evaluated based on responses from 306 customers using confirmatory factor analysis and structural equation modeling. The results showed that product risk, financial risk, security risk, and privacy risk impacted on perceived satisfaction. Besides, product risk, privacy risk, and perceived satisfaction influenced purchase intentions. Thus, this study focused on the influences of product risk, financial risk, security risk, and privacy risk on their cognitive attitudes toward websites. That means the more consumer perceive security, the more they avoid shopping online. The study is important to show how perceived risk affects online shopping behaviors, and it invites marketers to make necessary adjustments to prevent perceived risks to increase and online shopping to decrease. The findings of this study suggest the creation of a framework on the effect of perceived risk types on online shopping. Managers need to take perceived risks into account when designing their electronic marketing channels. In addition, shopping websites should strengthen their transaction security by appropriately using various available resources and new information technologies.
After-school time use of urban adolescents: Effects on achievement, problem behaviors, and happiness

Abstract Leisure is a context for both risk and protection of adolescent well-being. Using a person-centered analysis, the present study examined the links between after-school time use and the adjustment of an urban sample of 7th–12th graders (n = 3,808), who self-reported on their leisure activities, school achievement, problem behaviors, and happiness. Results indicated that time use patterns were distributed in five clusters: Creative/Social, Productive/Home, High-Social/Sports, Uninvolved/Sports, and Uninvolved/Home. These patterns of time use varied by age, gender and SES, and were linked with adolescent outcomes in a way that adolescents involved with multiple constructive activities presented better adjustment compared with their either uninvolved or socially oriented counterparts. Specific groups of adolescents were at higher risk for problem behaviors linked to after-school time use. These findings have relevant implications for evidence-based interventions and policies aiming at promoting adolescent well-being and targeting at-risk populations of youth.
Rigor With or Without Templates? The Pursuit of Methodological Rigor in Qualitative Research

The domain of qualitative research is replete with templates, standard protocols for the analysis of qualitative data. The use of such templates has sometimes been considered as automatically enhancing the rigor of qualitative research. In this article, we challenge the view that in the context of qualitative research, rigor is tied into the application of established protocols. Instead, we argue that rigor emanates from the way in which researchers engage in a deliberate reasoning process of inferring theoretical claims from their data. Such reasoning exists outside of templates, although it may make use of templates. Framing rigor as an emergent quality of reasoning, we distill the main processes through which qualitative researchers derive inferences from data and provide criteria for reflecting on the rigor with which they do so. We then extend these criteria into a set of practical recommendations through the presentation of examples and the framing of questions to focus researchers’ thinking on the application of the criteria. In doing so, we aim to help qualitative researchers to conduct research that leads to rigorously derived theoretical insights without having to resort to templates to attempt to do so.
ECM deposition is driven by caveolin-1–dependent regulation of exosomal biogenesis and cargo sorting

The composition and physical properties of the extracellular matrix (ECM) critically influence tumour cell behaviour, and ECM deposition and remodelling by stromal fibroblast populations is therefore pivotal for tumour progression. The molecular mechanisms by which stromal and tumour cell populations regulate ECM layering are poorly understood. Tumour-stroma interaction is critically dependent on cell-cell communication mediated by exosomes, small vesicles secreted by most cell types and generated within multivesicular bodies (MVBs). Here, we show that caveolin-1 (Cav1), an essential regulator of stromal remodelling and tumour cell fate, plays a central role in modulating both exosome biogenesis and exosomal protein cargo sorting through cholesterol-dependent mechanisms. Quantitative proteomics profiling revealed that a major share of Cav1-dependent exosomal cargoes are compsed of ECM proteins, one of the most important components being tenascin-C (TnC). Comparative functional assays demonstrated that Cav1 is required for fibroblast-derived exosomes to depose ECM and promote tumour cell invasiveness. Exosomes purified from Cav1WT cells, but not those from Cav1-null cells, were able to nucleate distant stromal niches in different organs in vivo. These findings suggest a key role for Cav1 as a cholesterol rheostat in MVBs, and seems to determine ECM deposition by eliciting ECM component sorting into specific exosome pools. These results, together with previous work, support a model in which Cav1 is a central regulatory hub for tumour-stroma interactions through a novel exosome-dependent ECM deposition mechanism.
Building Bridges with Latina/o Parents: Lessons from a College Access Program

ABSTRACT This research is based on a collaborative project with the University Scholars Program (USP), a college access program that serves middle and high school students who will be the first in their families to attend college. In this paper, we draw upon in-depth and focus group interviews with Latina/o parents whose children are enrolled in a college access program. Findings demonstrate participants’ challenges to engagement, a disconnect between the understanding of roles, desires for leadership cultivation and positive and negative aspects of information dissemination. Recommendations are provided to strengthen college access programs’ partnerships with Latina/o parents.
Multiple Dentigerous Cysts in a Child: A Case Report and Radiographic Follow-up

The aim of this study is to describe a case of dentigerous cysts of a young patient successfully treated as well as clinical and radiographic follow-up . A 10-year-old female patient was referred to the Buccomaxillofacial Surgery and Traumatology Service of the Regional University Hospital of Campos Gerais. The patient’s panoramic radiograph revealed a well-defined radiolucent unilocular area associated to the crown of the second permanent right lower molar, which was impacted. In addition, the permanent upper canines were enclosed, suggesting a dentigerous cyst. A conservative treatment was determined, through marsupialization of the lesions. The histopathology examination confirmed the clinical diagnosis of dentigerous cysts. Longitudinal clinical and radiographic monitoring was essential to certify the regression of the lesion, as well as bone neoformation, thus promoting the eruption and maintenance of the affected permanent teeth.
COGNITIVE DIVERSITY AMONG EFL LEARNERS: IMPLICATIONS FOR TEACHING IN HIGHER EDUCATION

With a theory-driven interest in the factors that make some language learners more successful than others, this study attempts to measure the cognitive diversity level of EFL learners at a Saudi university. To achieve this purpose, the Ehrman and Leaver’s questionnaire of learners’ cognitive profiles (Ehrman & Leaver, 2003) was adapted, translated into Arabic, and then randomly distributed to foundation year students taking English as a Foreign Language as a main course. The overall results reveal that the cognitive diversity among students is considerable. It ranges between moderate to high, according to the Simpson Diversity Index (Simpson, 1949). On this account, several implications are suggested to improve the quality of EFL teaching at the university level. These implications and recommendations are mostly directed to the committees concerned with qualification assurance or professional development.

Challenges of Online Education during COVID-19 Pandemic in Nepal

Covid-19 urged colleges and universities to shut down. The online education that nourished after COVID-19, has been challenging in Nepal because students, teachers, and administrators were not prepared for it. Stakeholders of education should work in many areas to enhance the effectiveness of online education and make it complementary to classroom education.
Hourly Oil Price Volatility: The Role of COVID-19

In this paper, we study the evolution of hourly oil price volatility. Using multiple measures of oil price volatility, we conclude that volatility increased following the onset of COVID-19. After controlling for conventional predictors of oil price volatility, we show that COVID-19 cases and deaths led to an increase in daily oil price volatility by between 8% and 22%. Our results pass a battery of robustness tests.
An understudied population? Exploring the factors associated with fear of crime in a semi-rural environment

ABSTRACT The intersection of fear of crime and media consumption has been examined in urban environments extensively. However, like many aspects of criminal justice research, much less is known about these concepts in non-urban environments. Further, there is an assumption that the processes of how media will influence fear of crime will work similarly in non-urban environments. This question remains open to empirical examination. In this paper, we investigate the relationship between media consumption and fear of crime in a semi-rural environment. Using data collected via telephone survey, and conducted within a selected non-urban community, we examine the relationship between media consumption and fear of crime while controlling for a host of confounders. Results indicated that media consumption is related to fear of crime among this specialized sample. However, this relationship becomes nonsignificant once perceived disorder is introduced. Findings and implications are discussed.
