PECVD SiNx Thin Films for Protecting Highly Reflective Silver Mirrors: Are They Better Than ALD AlOx Films?

Protection of silver surface from corrosion is an important topic, as this metal is highly susceptible to damage by atomic oxygen, halogenated, acidic and sulfur-containing molecules. Protective coatings need to be efficient at relatively small thicknesses, transparent and must not affect the surface in any detrimental way, during the deposition or over its lifetime. We compare PECVD-deposited SiNx films to efficiency of ALD-deposited AlOx films as protectors of front surface silver mirrors against damage by oxygen plasma. Films of different thickness were deposited at room temperature and exposed to O2 ECR-plasma for various durations. Results were analyzed with optical and SEM microscopy, pulsed GD-OES, spectroscopic ellipsometry and spectrophotometry on reflection. Studies indicate that both films provide protection after certain minimal thickness. While this critical thickness seems to be smaller for SiNx films during short plasma exposures, longer plasma treatment reveals that the local defects in PECVD-deposited films (most likely due to erosion of some regions of the film and pinholes) steadily multiply with time of treatment and lead to slow drop of reflectance of SiNx-protected mirrors, whereas we showed before that ALD-deposited AlOx films reliably protect silver surface during long plasma exposures.
Safety first: extending UTAUT to better predict mobile payment adoption by incorporating perceived security, perceived risk and trust

Purpose The purpose of this study is to investigate the antecedents of behavioral intention to use (BIU) mobile payment in Indonesia by extending unified theory of acceptance and use of technology (UTAUT) with user privacy constructs, namely, perceived security (PS), perceived risk (PR) and trust (Tr). Design/methodology/approach This is a quantitative research using the covariance-based structural equation modeling method, whereby the researchers conducted an online survey and distributed online questionnaires to users of mobile payment from all over Indonesia to obtain the data. The sample in this study consisted of 358 respondents. Findings This study found that social influence, facilitating conditions, PS, performance expectancy and Tr have a significant and direct influence on BIU mobile payment. PR was not found to have a significant and direct relationship with BIU, but it was indirectly affecting the latter through Tr as the mediating variable. Originality/value The researchers modified UTAUT by incorporating PS, PR and Tr to create a more comprehensive model in predicting mobile payment adoption, especially considering the risky nature of digital transactions in emerging economies like Indonesia. This extended model has never been thoroughly explored in previous studies.
GIS Day across the Association of Research Libraries: Outreach, Education, and Collaboration

ABSTRACT GIS Day is an annual, international celebration of geographic information systems (GIS) and geospatial technologies that provides organizations with an opportunity to help others learn about the real-world applications and positive societal impacts of geography and GIS, highlight services, and celebrate accomplishments. Many academic libraries participate in GIS Day programs, using this well-known event to engage with their campus and local communities. In this article, we build on earlier research conducted by Weimer, Olivares, and Bedenbaugh to reassess the landscape of Association of Research Libraries (ARL) member involvement in GIS Day programs and, in particular, how these events demonstrate the educational and collaborative aspects of geospatial information services in libraries. For our web content analysis, we specifically focus on gathering information about GIS Day programs in 2019 and 2020, allowing for an examination of how libraries participating in GIS Day responded to the operational challenges posed by the COVID-19 pandemic, as well as new opportunities that may have emerged during this period. Finally, we offer our own 2020 GIS Day program as a brief example highlighting how it led to our first cross-institutional collaboration and fostered new opportunities for promoting and partnering on digital scholarship projects at our institutions.
L’(in)définitude des lectures relatives des superlatifs de qualité et de quantité

Dans certaines langues THE est obligatoire avec les superlatifs de qualite mais impossible avec le quantitatif MOST. J’analyse cette difference d’(in)definitude comme etant correlee a une difference de position : MOST est dans Spec,Meas (tout comme MANY/MUCH) et D° contient un element nul ([D°O]) semantiquement invisible, tandis que les superlatifs de qualite sont des modifieurs qui forcent la presence de l’article defini sous D° ([D°THE]). J’analyse le statut quasi-indefini de la lecture relative des superlatifs de qualite comme resultant du mouvement de EST a travers Spec,DP, qui a comme resultat que [D°THE] se traduit par un existentiel et l’unicite est calculee au niveau du IP.
Phase Compensation Technique for Effective Heat Focusing in Microwave Hyperthermia Systems

In this paper, effective electromagnetic (EM) focusing achieved with a phase compensation technique for microwave hyperthermia systems is proposed. To treat tumor cells positioned deep inside a human female breast, EM energy must be properly focused on the target area. A circular antenna array for microwave hyperthermia allows EM energy to concentrate on a specific target inside the breast tumor. Depending on the cancerous cell conditions in the breast, the input phases of each antenna are calculated for single and multiple tumor cell locations. In the case of multifocal breast cancer, sub-array beam focusing via the phase compensation technique is presented to enhance the ability of EM energy to concentrate on multiple targets while minimizing damage to normal cells. To demonstrate the thermal treatment effects on single and multiple tumor locations, the accumulation of the specific absorption rate (SAR) parameter and temperature changes were verified using both simulated and experimental results.
Gene action for grain protein content in durum wheat

The aim of this study was to determine the gene action and combining ability of durum wheat for grain protein content. During the three year period a diallel cross was carried out with five modern parents of durum wheat – ‘Victoria’, ‘Deni’, ‘Superdur’, ‘Progres’ and ‘Predel’. Ten hybrid combinations and the parents were grown in the experimental field of the Field Crops Institute, Chirpan. The experiment was performed by the randomize block method design in three replications. It was found that in the inheritance of grain protein content dominance and overdominance in positive and negative directions were observed. Statistical processing of the results showed that both additive and non-additive genetic effects have influenced on inheritance. Non-additive gene effects (SCA) had a greater role in inheritance. This suggests that an effective selection for this trait could begin in later generations. The combining ability analysis has identified two good general combinators (Predel and Superdur varieties) that could be used as donors to increase the values of the trait protein content in grain. Several crosses showing positive and significant SCA effects have also been identified, suitable for achieving reliable transgressive genotypes.
Predictors of Teachers’ Turnover and Transfer Intentions: A Multiple Mediation Model of Teacher Engagement

The purpose of this research was to examine how teachers’ level of engagement might predict their likelihood of leaving their current positions. This study used cross-sectional survey data gathered on 188 elementary school teachers. A multiple mediation model was used to examine the effects of organizational (individual-level climate, psychological climate) and personal (burnout, engagement, job stress) predictors on turnover and transfer intentions. Results from the study confirmed that individual-level climate was a significant predictor of teachers’ engagement, job stress, and burnout, which mediated its effect on turnover intention. Psychological climate had a direct effect on transfer intention but no reported indirect effects on teacher self-beliefs or turnover intention. The research findings provide a foundation for continued research, as well as a framework for understanding how school culture may influence teachers’ decisions to leave or transfer. The study identified a need for school leaders to understand that the perceptions of the school’s environment and teachers’ self-beliefs have a significant effect on teacher turnover and intent to transfer. Results from this study offer explicit recommendations and guidance to school leaders for how to improve teacher retention; it is one of a small number of studies in educational contexts to provide such guidance for teacher engagement.
Investigating the neutral sodium emissions observed at comets

Neutral sodium emission is typically very easy to detect in comets, and has been seen to form a distinct neutral sodium tail at some comets. If the source of neutral cometary sodium could be determined, it would shed light on the composition of the comet, therefore allowing deeper understanding of the conditions present in the early solar system. Detection of neutral sodium emission at other solar system objects has also been used to infer chemical and physical processes that are difficult to measure directly. Neutral cometary sodium tails were first studied in depth at comet Hale-Bopp, but to date the source of neutral sodium in comets has not been determined. Many authors considered that orbital motion may be a significant factor in conclusively identifying the source of neutral sodium, so in this work details of the development of the first fully heliocentric distance and velocity dependent orbital model, known as COMPASS, are presented. COMPASS is then applied to a range of neutral sodium observations, including spectroscopic measurements at comet Hale-Bopp, wide field images of comet Hale-Bopp, and SOHO/LASCO observations of neutral sodium tails at near-Sun comets. The author finds that COMPASS is relatively successful at reproducing the morphology of the neutral sodium tails seen in wide field images, and to a lesser extent the intensity profiles produced by spectroscopic measurements. The success of COMPASS indicates that the current understanding of the physics of the production and evolution of neutral cometary sodium is broadly accurate. Using a simplistic dust tail source the author also finds that a source of neutral sodium within the dust tail is likely to result in a secondary neutral sodium tail feature, that has not yet been observed to the best of their knowledge.
Teacher’s Assessment of Gender Differences in School Performance, Social Skills, and Externalizing Behavior From Fourth Through Seventh Grade

Gender differences in teacher ratings of academic performance, social skills, and externalizing behavior were examined from fourth through seventh grade in a group of 1,023 students from 65 primary schools. Cohen’s d and t tests and were used to report the magnitude of gender differences, and structural equation modeling was used to evaluate cross-domain influences in latent cascade models. Girls received significantly more positive teacher ratings than boys, but the differences leveled more out in the social and behavioral domain than in the academic. Teacher assessments of academic performance predicted future social skills to a larger extent than vice versa for both genders.
Screening Depression and Anxiety via Brief Measures of Psychological Inflexibility

We evaluated the usefulness of scores from two transdiagnostic scales—the 8-item version of the Avoidance and Fusion Questionnaire for Youth and the second edition of the Avoidance and Action Questionnaire—for estimating symptom severity on two measures of depression and anxiety. Responses from 797 college students, who mostly identified as White and female, to both measures of psychological inflexibility were analyzed to determine how well scores estimated anxiety and depression above or below a given severity level and at specific categories of symptom severity. Findings indicated that scores from both measures were acceptable to excellent screeners of concurrent ratings of anxiety and depression. Results varied somewhat depending on the measure used, level of severity targeted, and scope of screening. By investigating the screening accuracy of these transdiagnostic measures and potential cut scores to ease in interpreting results, we hope these measures might prove useful for addressing barriers in public health screening endeavors.
Building Britannia: Pre-Flavian Private and Public Construction across Southern Britain

ABSTRACT Excavation of the Roman tilery at Little London, Pamber, Hampshire, has prompted a reassessment of the dating of relief-patterned tile, assigning the bulk of production to the Claudio-Neronian period rather than the late first to mid-/late second century. This material has been privileged for retention in excavation archives but can now be seen as a proxy for the manufacture of a much wider range of ceramic building material, typically discarded on site, which, in the case of products from Little London and pre-Flavian Minety (Wiltshire), travelled distances of up to 100 km. Redating implies more extensive public and private building in town and country south and east of the Fosse Way before the Flavian period than has previously been envisaged. While private building included the construction of bath-houses, heated rooms and the provision of roofing materials, public building, we suggest, provided tabernas et praetoria along the principal roads of the province. In the private sphere such building provides a possible context for Dio Cassius’ mention of the recall and confiscation of large loans made to Britons before the Boudican rebellion. Finally, consideration of fabric needs to be added to the criteria for retaining ceramic building material in excavation archives.
The impacts and success factors of a work-from-home service-learning internship during COVID-19

PurposeCOVID-19 has changed the way we teach and learn, including service-learning (S-L). This study examines the impacts of the work-from-home (WFH) mode on the work performance and learning outcomes of student interns on an eight-week S-L internship programme, and the key factors in terms of its success.Design/methodology/approachA qualitative research methodology is adopted by interviewing nine student interns and four supervisors from three community partner organisations (CPOs) to understand their experiences of how the WFH mode has impacted intern work performance and learning outcomes. Thematic analysis is used for the data analysis.FindingsThe interns uncover a number of negative WFH impacts on the S-L internship, including ineffective communication and management practice, low work efficiency and quality, a lack of task variety and learning opportunities and distractions in the home environment. Furthermore, five critical factors for WFH success are also identified, including prior preparation, effective communication systems, personal motivators at work, the nature of the job in relation to it being suited to the WFH mode, and organisational support.Originality/valueThe study examines impacts on student work performance and learning outcomes in an S-L summer internship programme operating under the WFH mode as a result of the COVID-19 pandemic. Key success factors and practical recommendations have been developed for enhancing the future success of S-L internships operating under the WFH mode.
Some New Coupled Fixed-Point Findings Depending on Another Function in Fuzzy Cone Metric Spaces with Application

In this paper, we introduce the new concept of coupled fixed-point (FP) results depending on another function in fuzzy cone metric spaces (FCM-spaces) and prove some unique coupled FP theorems under the modified contractive type conditions by using “the triangular property of fuzzy cone metric. ” Another function is self-mapping continuous, one-one, and subsequently convergent in FCM-spaces. In support of our results, we present illustrative examples. Moreover, as an application, we ensure the existence of a common solution of the two Volterra integral equations to uplift our work.
Undergraduate Students’ Experiences of the Use of MOOCs for Learning at a Cambodian University

Currently, some universities in Cambodia are exploring the usage of Massive Open Online Courses (MOOCs), which can support education by allowing cost-free independent learning for university students. For effective implementation, it is fundamental to understand the current Cambodian ecosystem, how universities implement MOOCs for teaching, and how students use them for learning. Due to a current gap in the literature on this matter, this research work aims to investigate students’ awareness of MOOCs, usage, and difficulties encountered with their adoption for learning. This research work is a case study of a university in Cambodia, and it adopts a mixed-mode approach involving a quantitative questionnaire, followed by qualitative semi-structured interviews. Currently, many students are not aware of MOOCs, and regarding those using them, they report a low level of organized effort, which points out to the fact that students are in general not very organized and systematic in the way they approach learning using MOOCs. Furthermore, a major issue still lies in the way these courses are implemented in the curriculum and the learning activities, underlined by the type of ICTs affordances currently exploited by the usage of MOOCs for learning.
Oil Palm Inflorescence Sex Ratio and Fruit Set Assessment in dura × pisifera Biparental Progenies on Fibric Peat Soil

This study investigated oil palm inflorescence sex ratio (ISR) and fruit set (FS) yield among 24 dura × pisifera biparental progenies on fibric peat soil, hybridized from ten genetic origins. Three-month intervals of data collection on ISR and “S-shape” procedure for FS determination were carried out in an independent complete randomized design for one year. Based on the assessment of individual progenies, analysis of variance revealed the existence of genetic heterogeneity. Five of the progenies had the highest ISR above 90%. However, 20.83% of the progenies (PK4841, PK4674, ECPHP415, ECPHP550, and PK4118) had the best normal range of ISR, indicating FS declined being influenced by ISR. Therefore, only 12.50% of the progenies (PK4674, PK4465, and PK4482) were above 60% FS critical level. Correlation analysis verified that ISR depends on the female flower and progeny PK4674 (65.78%) and PK4465 (62.62%) had the best FS and fruit to bunch. Among the parental origins, Deli Serdang × Cameroon was statistically the best for male flower production at 29.40% and ISR at 72.22%. The highest FS was recorded in Deli Banting × AVROS (54.00%) and Angola × AVROS (53.78%). However, molecular research, such as microsatellite molecular markers if concurrently used as a selection criterion with the present conventional study, could present further details to complement the present findings.
Extending the theory of planned behavior: factors fostering millennials’ intention to purchase eco-sustainable products in an emerging market

Based on the Theory of Planned Behavior model, this exploratory study aims to examine factors fostering millennials’ purchasing intentions toward eco-sustainable products in emerging markets and assess the interrelationship between environmental knowledge, environmental concern, subjective norms, green attitude, and perceived behavior. Data was collected from 446 Indian millennials using convenience sampling. The data were analyzed using the IBM SPSS and AMOS package using exploratory factor analysis, confirmatory factor analysis, and Structural Equation Modeling. The results revealed that environment knowledge, environmental concern, subjective norms, and perceived behavior factors significantly fostered green attitude. Millennial green attitude positively affected purchase intention and influenced millennials’ purchase behavior both directly and indirectly. The study variables had a positive interrelationship, except for subjective norms and perceived behavior. Environmental knowledge and environmental concerns were the strongest determinants of GPI toward GPB.
Chrysotoxine attenuates sevoﬂurane-induced neurotoxicity in vitro via regulating PI3K/AKT/GSK pathway

Objective: The aim of this study is to investigate the neuroprotective effect of chrysotoxine (CTX) on sevoflurane-treated nerve cells and uncover the potential regulation mechanism. Methods: Nerve cells treated with sevoflurane and CTX were subjected to MTT and apoptotic detection. Cell apoptosis and oxidative stress were detected by flow cytometry (FCM) and ELISA assays. In addition, immunoblot assay was performed to study the signaling pathway affected by CTX treatment. Results: CTX treatment promoted the cell viability and suppressed the apoptosis of sevoflurane-treated SH-SY5Y cells. In addition, CTX inhibited the sevoflurane-induced oxidative stress response and inflammatory response in nerve cells. Mechanically, CTX ameliorated neurotoxicity through activating the PI3K/AKT/GSK signaling pathway. Conclusion: Therefore, CTX can serve as a promising drug target for treating anesthetics-induced neurotoxicity.
Dual-view 3D human pose estimation without camera parameters for action recognition

The purpose of 3D human pose estimation is to estimate the 3D coordinates of key points of the human body directly from images. Although multi-view based methods have better performance and higher precision of coordinate estimation than a single-view based, they need to know the camera parameters. In order to effectively avoid the restriction of this constraint and improve the generalizability of the model, a dual-view single-person 3D pose estimation method without camera parameters is proposed. This method ﬁrst uses the 2D pose estimation network HR-net to estimate the 2D joint point coordinates from two images with different views, and then inputs them into the 3D regression network to generate the ﬁnal 3D joint point coordinates. In order to make the 3D regression network fully learn the spatial structure relationship of the human body and the transformation projection relationship between different views, a self-supervised training method is designed based on a 3D human pose orthogonal projection model to generate the virtual views. In the pose estimation experiments on the Human3.6 dataset, this method achieves a significantly improved estimation error of 34.5 mm. Furthermore, an action recognition based on the human poses extracted by the proposed method is conducted, and an accuracy of 83.19% is obtained.
