Enhancing active learning in remote collaboration: An experience in teaching functional materials

COVID-19 deeply changed traditional teaching, forcing the adoption of emergency remote teaching (ERT). ERT provided flexibility to teaching/learning activities (TLAs) yet affecting face-to-face communication and sociality. In this work, we present specific constructive alignment for an ERT/extended classroom course at Politecnico di Milano, as well as the tools involved. Two tutorials introduced the learners to the final essay, encouraged collaborative discussion, and promoted self-learning. The final essay, to be done individually or by joining a group, was part of the evaluation alongside a written exam. An evaluation rubric was shared when launching the topics of the essay, and setting the evaluation criteria. Results show how almost half of the essays were delivered by learners working alone, despite the attempts to promote collaborative interaction. Additionally, synchronous class attendance was only 55%, attributed to the availability of recordings and slides. Among the unattended results, the learners positively perceived TLAs and generated new collective knowledge, which was shared on the research group's Instagram profile.
Medio-lateral and lateral edge friction in indoor sports shoes

Abstract It has previously been speculated that the occurrence and severity of lateral ankle sprain injuries is linked to excessive shoe–surface friction. Especially, the lateral parts of the shoe outsole are suggested to play an important role in such scenarios but have never been quantified in a systematic manner. Therefore, the purpose of this study was to investigate the variation of friction of indoor sport shoes with foot orientation and compare it to the traditional industry forefoot friction test standard. We modified the ISO:13287:2019 test for footwear slip resistance and positioned the shoe on its forefoot and lateral edge while replicating medio-lateral movements similar to previously reported ankle sprain incidents. All tests were conducted on an indoor vinyl/sport surface. The results from the modified setups were compared to those following the anterior-posterior orientated ISO standard. Medio-lateral friction was on average 17% lower and lateral edge friction 24% lower than anterior-posterior forefoot friction (p < .001). However, linear regression showed that the forefoot test could only explain 36% and 35% of the variation in medio-lateral and edge friction. This suggests that motion-specific tests are necessary to determine footwear friction properties meaningfully. These findings could have important implications for future research and product testing in the field of footwear friction, safety and injury prevention.
Vegetation disturbances characterization in the Tibetan Plateau from 1986 to 2018 using Landsat time series and field observations

Disturbances in vegetated land could dramatically affect the process of vegetation growth and reshape the land cover state. The overall greenup of vegetation on the Tibetan Plateau (TP) has almost served as a consensus to date. However, we still lack consistent acquisitions on the timing, the spatial patterns, and the temporal frequency of vegetation disturbance over the TP, limiting the capacity for planning land management strategies. Therefore, we explored the spatiotemporal pattern and variation of vegetation disturbances across the TP during the past decades and analyzed the disturbance agents. We utilized 37-year Landsat time series images and field observations coupled with a temporal segmentation approach to characterize the spatiotemporal pattern of vegetation disturbances across the TP for the period 1986–2018. The results from this study revealed that 75.71 M ha (accounting for 29.34% of TP’s area) vegetation area underwent at least one disturbance, of which 8.44 M ha area ever experienced large-scale disturbances (disturbance area greater than 0.9 ha and disturbance magnitude (the difference between the spectral value of pre-disturbance and that of post-disturbance) over 0.2). Further, the spatial distributions of these large-scale disturbances varied over time: before 2002, the disturbed sites were evenly distributed over the southeast part of the TP probably induced by overgrazing and unscientific livestock management, while after 2002, most disturbances were concentrated in the south of the Yarlung Tsangpo, mainly caused by anthropogenic activities, such as urban area, roadways, railway, and water control projects. This study presents an effort to characterize vegetation disturbances and their variations over the past decades on the TP, which provides crucial insights toward a complete understanding of vegetation dynamics and its causal relationship with human activities.
Associations of sexual behavioral aspects and sexual scripts among college students: A cross-sectional study

Abstract Background Sexual scripts (SSs) are formed based on the gendered culture in societies. Objective To evaluate the associations between the sexual behavioral aspects: capacity, motivation, performance, and SS amongst Iranian college students. Materials and Methods From September to December 2020, we recruited 400 college students who were married, had no acute or chronic diseases, was no drug abuser, and were not pregnant at the time of the study. The demographic questionnaire, sexual behavior assessment, and SSs questionnaires were completed by all the participants. Descriptive statistics and inferential statistics, Pearson correlation coefficient, and multivariate regression were used for data analysis. We also employed an independent t test to compare sexual behavior-related variables: sexual capacity, sexual performance, sexual motivation, and SSs in 2 female and male student groups. Results Men and women were significantly different in the component of sexual behaviors. Women had higher sexual motivation than men. The participants' SSs were positively correlated with all 3 components of sexual behaviors at a significant level of p ≤ 0.001. Of demographic characteristics, only women's age had a significant correlation with sexual capacity. For men, education level and economic status were positively correlated with all components of men's sexual behaviors. Conclusion Sexual behaviors seem to be highly gendered, particularly, in the motivational component. Based on the results, SSs are more determinant than demographics. We recommend gender-sensitive and cultural-oriented sexuality educations for Iranians to provide fundamental changes in the SSs.
Comparison of Neuroform Atlas Stent-Assisted Coiling and Coiling Alone in Ruptured Intracranial Aneurysms: A Propensity Score Matching Analysis

BACKGROUND: Although Neuroform Atlas stent is commonly used in stent-assisted coiling (SAC) to treat ruptured intracranial aneurysms (RIA), its safety and efficacy remain controversial. OBJECTIVE: To assess the safety and efficacy of SAC using Neuroform Atlas for treating RIA compared with coiling alone by performing a propensity score matching analysis. METHODS: RIA treated with coiling alone and SAC between January 2017 and May 2021 were retrospectively reviewed. Demographics, periprocedural complication rates, angiographic outcomes, and clinical outcomes of the SAC using Neuroform Atlas group and the coiling-alone group were analyzed with 1:1 propensity score matching. RESULTS: A total of 375 aneurysms were enrolled, and 274 (63.1%) aneurysms were treated with coiling alone. In total, 101 (26.9%) aneurysms were treated with SAC, and Neuroform Atlas stent was used in 71 aneurysms. In propensity score matching, the SAC using Neuroform Atlas group showed higher incidence of complete occlusion (69.0% vs 56.3%, P = .029), lower rate of recanalization (11.3% vs 25.4%, P = .011), and lesser need for retreatment (7.0% vs 16.9%, P = .016) compared with the coiling-alone group. However, there were no significant differences in periprocedural complications such as intraprocedural thrombosis or postprocedural cerebral infarct between the 2 groups. CONCLUSION: The use of Neuroform Atlas is safe and effective for SAC in RIA with comparable procedure-related complication rates but better angiographic outcome in comparison with coiling alone.
Optimization of Low Salinity Water/Surfactant Flooding Design for Oil-Wet Carbonate Reservoirs by Introducing a Negative Salinity Gradient

Engineered water surfactant flooding (EWSF) is a novel EOR technique to reduce residual oil saturation; however, it becomes quite challenging to obtain Winsor Type III microemulsion and the lowest IFT under actual reservoir conditions if only low salinity water is used. The main objective of this study was to design a negative salinity gradient to optimize the performance of the hybrid method. Three corefloods were performed on carbonate outcrop samples. The injection sequence in the first test was conventional waterflooding followed by optimum engineered water injection (2900 ppm) and finally an EWSF stage. The second and third tests were conducted using a varying negative salinity gradient. Engineered water for this study was designed by 10 times dilution of Caspian Sea water and spiking with key active ions. A higher salinity gradient was used for the first negative salinity gradient test. A total of 4300 ppm brine with 1 wt% surfactant was injected as a pre-flush after waterflooding followed by a further reduced salinity brine (~1400 ppm). The second negative salinity gradient test consisted of three post-waterflooding injection stages with salinities of 4600, 3700, and 290 ppm, respectively. Up to 8% and 16% more incremental oil recovery after waterflooding was obtained in the second and third tests, respectively, as compared to the first test. The descending order of brine salinity helped to create an optimum salinity environment for the surfactant despite surfactant adsorption. This study provided an optimum design for a successful LSSF test by adjusting the brine salinity and creating a negative salinity gradient during surfactant flooding. A higher reduction in residual oil saturation can be achieved by carefully designing an LSSF test, improving project economics.
FDI Inflows and Domestic Firms: Adjustments to New Export Opportunities

We investigate the long-term effects of export opportunities to a large destination market on multinational affiliates and domestic firms in a low-income host country. The US-Vietnam Bilateral Trade Agreement reduced US import tariffs on exports from Vietnam. Tariff reductions led to entry of foreign and private firms and to employment expansion in formal manufacturing, with foreign entrants contributing most to employment growth. State firms stall employment reallocation through slower contraction. Half of tariff-induced foreign entrant growth is post-entry and exporter-driven. Foreign entrants are from non-US sources, highlighting the importance of studying FDI from multiple source countries in a lower-income host
Understanding Student Navigation Patterns in Game-Based Learning

Research on learning analytics (LA) has focused mostly at the university level. LA research in the K–12 setting is needed. This study aimed to understand 4,115 middle school students’ learning paths based on their behavioural patterns and the relationship with performance levels when they used a digital learning game as their science curriculum. The findings showed significant positive relationships between various tool uses and performance measures and varied tool use patterns at different problem-solving phases by high- and low-performing students. The results indicated that students who used tools appropriately and wisely, given the phase they were at, were more likely to succeed. The findings offered an insightful glimpse of learners’ navigation patterns in relation to their performance and provided much-needed empirical evidence to support using analytics for game-based learning in K–12 education. The findings also revealed that log data cannot explain all learners’ actions. Implications for both research and practice are discussed.
Understanding the relative roles of local environmental, geo‐climatic and spatial factors for taxonomic, functional and phylogenetic β‐diversity of stream fishes in a large basin, Northeast China

Abstract The primary objective of this study was to determine the relative roles of local environmental (Local), geo‐climatic (Geo), and spatial (Spatial) factors to taxonomic, functional, and phylogenetic β‐diversity of stream fish in a large basin in Northeast China. We quantified the current biodiversity patterns of fish communities in the Hun‐Tai River using β‐diversity. We assessed (i) corresponding contributions of turnover and nestedness within the taxonomic, functional, and phylogenetic β‐diversity of fishes; (ii) correlations among β‐diversity facets (i.e., taxonomic, functional, and phylogenetic facets); (iii) relative contributions of Local, Geo, and Spatial factors to β‐diversity. We collected fish communities from 171 sampling sites. Mantel tests were used to examine the correlation of three facets of β‐diversity and their components (i.e., total, nestedness, and turnover). Distance‐based redundancy analysis and variation partitioning assess the relative contributions of Local, Geo, and Spatial factors to β‐diversity. We found that turnover is the main driving mechanism for β‐diversity in fish. Among the facets of β‐diversity, taxonomic and phylogenetic facets have strong ecological information association. Spatial factors have a general contribution to various facets of β‐diversity and its components. From aspects of fish β‐diversity conservation, connectivity and habitat heterogeneity need to be maintained in the entire aquatic environment. In addition, protecting taxonomic β‐diversity is helpful for maintaining phylogenetic β‐diversity.
Culture in Physical Activity: The Contribution of Basic Psychological Needs and Goal Orientation

Numerous variables affect motivation in physical activity (PA) with culture being an understudied variable. Self-determination theory’s basic psychological needs (BPN) includes a combination of autonomy, competence, and relatedness in PA; however, cultural definitions pit autonomy and relatedness against each other. Thus, this study aims to investigate the moderating role of culture on relationships between BPN, goal orientations (ego, task) for PA, and PA behavior. A survey was implemented to 168 participants (109 females, 59 males; 92 Turks, 76 Americans) investigating students’ self-construal type, their basic psychological needs in exercise (BPNES), PA levels (Godin Leisure-Time Exercise Questionnaire/GLTEQ), and goal orientation types (Task and Ego Orientation in Sport Questionnaire/TEOSQ). Turks (n = 92) and Americans (n = 76) demonstrated distinct cultural differences in terms of the study variables. American students were more autonomous, task-oriented, and physically active than Turkish students. Results from the multi-group path analysis showed that there was a moderating role of culture between predictors (i.e., BPN Autonomy, BPN Relatedness, BPN Competence, Ego Orientation, and Task Orientation) and Physical Activity. Such that, the paths from predictors (i.e., BPNT Autonomy, BPNT Relatedness, BPNT Competence, Ego Orientation, and Task Orientation) to PA was not significant in Turkish cultural context. Results suggest that culturally tailored approaches to PA interventions are critical in supporting motivation for physical activity and further research is needed to explore different culturally relevant motivational drivers for PA among adults.
Worsening Rhinosinusitis as a Prognostic Factor for Patients with Nasopharyngeal Carcinoma: A Retrospective Study

Rhinosinusitis is common in patients with nasopharyngeal carcinoma (NPC). Our study aimed to explore the role of rhinosinusitis severity in NPC prognosis. Medical records and radiologic examinations of 90 patients with NPC at a single medical center from 2009–2016 were retrospectively analyzed. The Lund–Mackay (L–M) score was obtained for each patient before and after 6 months of treatment. Rhinosinusitis diagnosis was based on L–M scores of ≥4. L–M score differences were calculated as pre-treatment rhinosinusitis (PRRS) minus post-treatment rhinosinusitis (PSRS). L–M score difference was sub-grouped into “L–M scores > 0”, “L–M scores = 0”, and “L–M scores < 0”. Clinical staging of our patients based on the American Joint Committee on Cancer 7th edition were: stage I in nine, stage II in seventeen, stage III in twenty-two, and stage IV in forty-two patients; twenty-seven (30%) patients had died. PRRS incidence was 34.4%, and PSRS was 36.7%. Median of L–M scores difference was 0 (−2.2). L–M score difference was an independent prognostic factor for the overall survival of patients with NPC (p < 0.05). Therefore, worsening rhinosinusitis was a prognostic factor for patients with NPC. Clinicians should consider NPC as a warning sign of poor prognosis during routine follow-ups.
Exploratory factor analysis of a Force Concept Inventory data set

We perform a factor analysis on a ``Force Concept Inventory'' (FCI) data set collected from 2109 respondents. We address two questions: the appearance of conceptual coherence in student responses to the FCI and some consequences of this factor analysis on the teaching of Newtonian mechanics. We will highlight the apparent conflation of Newton's third law with Newton's first law in one of the FCI questions and suggest an approach to teaching that may avoid this issue. We also note the absence of a distinct factor interpretable as relating specifically to kinematics. Furthermore, we identify and discuss some of the technical difficulties which may be encountered when performing factor analysis on categorical data sets, such as is the case with FCI data sets.
Time for a Measurement Check-Up: Testing the Couple’s Satisfaction Index and the Global Measure of Sexual Satisfaction Using Structural Equation Modeling and Item Response Theory

Relationship and sexual satisfaction are two central outcomes in the study of relationships and are commonly used in both academia and applied practice. However, relationship and sexual satisfaction measures infrequently undergo specific psychometric investigation. Ensuring that measures display strong psychometric performance is an important but under-tested element of replication that has come under more scrutiny lately, and adequate measurement of constructs is an important auxiliary assumption underpinning theory-testing empirical work. A measurement check-up was conducted, including Confirmatory Factor Analysis (CFA) to test factorial validity, measurement invariance to test for group comparability, and Item Response Theory (IRT) to assess the relationship between latent traits and their items/indicators. This format was used to evaluate the psychometric properties of the Couple’s Satisfaction Index (CSI) and the Global Measure of Sexual Satisfaction (GMSEX), two commonly used scales of relationship and sexual satisfaction with a sample of 640 midlife (40–59 years old) married Canadians who were recruited by Qualtrics Panels. Results of CFA suggested that both models were satisfactory. Invariance testing provided robust support for intercept invariance across all the groupings tested. IRT analysis supported the CSI and GMSEX, however, there was evidence that the GMSEX provided somewhat less information for those high on sexual satisfaction. This measurement check-up found that the CSI and GMSEX were reasonably healthy with some caveats. Implications are discussed in terms of replicability and meaning for scholars and practitioners.
Characterization of the influence of diet on Japanese quail.

The experiments were conducted in fields of the department of animal production- agriculture college – Tikrit University by adding different levels of onion and sumac to the quail dietary and know its effect on the chemical composition of the thigh and the percentage of some saturated and unsaturated fatty acids and measures the peroxide value. The quail was divided into five treatments: Treatment1 was controlled without adding, treatment 2 (3.5)g/kg of onion added, Treatment 3 (7)g/kg of onion added, treatment 4 (5)g/kg of sumac added. Treatment 5 (10)g/kg of sumac added. The results showed a high percentage of moisture in treatment 3 (73.08) % compared with the others; also, treatment 4 showed significant differences in fat percentage (7.50)% to the others. No significant differences led to protein and ash percentages between the five treatments. Regarding saturated fatty acids, treatments 1 and 4 showed significant differences in palmitic acid (7.98, 7.01)%, respectively. Stearic acid was high in treatment one than the others (9.10)%. Regarding saturated fatty acids didn’t notice significant differences between the five treatments, but about peroxide, the values in treatments 2, 3, 4 and 5 were lower than the control.

Effects of climate and land‐cover change on the conservation status of gibbons

Species shift their distribution in response to climate and land‐cover change, which may result in a spatial mismatch between currently protected areas (PAs) and priority conservation areas (PCAs). We examined the effects of climate and land‐cover change on potential range of gibbons and sought to identify PCAs that would conserve them effectively. We collected global gibbon occurrence points and modeled (ecological niche model) their current and potential 2050s ranges under climate‐change and different land‐cover‐change scenarios. We examined change in range and PA coverage between the current and future ranges of each gibbon species. We applied spatial conservation prioritization to identify the top 30% PCAs for each species. We then determined how much of the PCAs are conserved in each country within the global range of gibbons. On average, 31% (SD 22) of each species’ current range was covered in PAs. PA coverage of the current range of 9 species was <30%. Nine species lost on average 46% (SD 29) of their potential range due to climate change. Under climate‐change with an optimistic land‐cover‐change scenario (B1), 12 species lost 39% (SD 28) of their range. In a pessimistic land‐cover‐change scenario (A2), 15 species lost 36% (SD 28) of their range. Five species lost significantly more range under the A2 scenario than the B1 scenario (p = 0.01, SD 0.01), suggesting that gibbons will benefit from effective management of land cover. PA coverage of future range was <30% for 11 species. On average, 32% (SD 25) of PCAs were covered by PAs. Indonesia contained more species and PCAs and thus has the greatest responsibility for gibbon conservation. Indonesia, India, and Myanmar need to expand their PAs to fulfill their responsibility to gibbon conservation. Our results provide a baseline for global gibbon conservation, particularly for countries lacking gibbon research capacity.
Convergence and approximation results for measurable multifunctions

In this note we consider measurable multifunctions taking values in a sepaxable Blanach space. We show that if F(w) C s-limrFn (w), then any Castaing representation of the F(.) can be obtained as the strong limit of Castaing representations of the Fn's. We also prove that any weakly measurable multifunction is the Kuratowski-Mosco limit of a sequence of countably simple multifunctions. Then we show that in reflexive Banach spaces this approximation property is equivalent to weak measurability. Finally we discuss the problem of measurability of the inferior and w-superior limits of a sequence of measurable multifunctions.
CNO isotopes and galactic chemical evolution

In order to quantitatively reproduce the chemical abundance gradient and the age-metallicity relation observed in the disk of the Galaxy, numerical models of galactic chemical evolution have been computed under different assumptions on the star formation and infall rates. The best fit to the observed data is obtained for a model with a constant star formation rate and a uniform infall rate of 5 x 10/sup -3/ M/sub sun/ kpc/sup -2/ yr/sup -1/. Models with other star formation laws do not reproduce the observed data as well.
