The Effects of Desmos and TI-83 Plus Graphing Calculators on the Problem-Solving Confidence of Middle and High School Mathematics Students

As technology in education continues to improve, research is necessary to assess the impact it is having on students’ confidence in the way students solve mathematics problems. The purpose of this quasi-experimental, non-equivalent control-group comparison study is to examine the impact the Desmos graphing calculator has on the problem-solving confidence of middle school and high school students as compared to students who use a TI-83 Plus graphing calculator while controlling for students’ math achievement scores. The students (N = 146) participating in this study were learning their respective mathematics material for an equivalent period of 12 weeks in order to determine whether students who used the Desmos calculator experienced a statistically significant difference in problem-solving confidence levels. Students in both groups took the assessment at the end of the 12-week period of learning and an Analysis of Covariance (ANCOVA) was used to test whether there was a significant difference in the scores of the Problem Solving Inventory (PSI). Results indicate that there was a statistically significant difference in problem-solving confidence scores between middle and high school students who used the Desmos graphing calculator as compared to students who used a TI-83 Plus graphing calculator, while controlling for student math achievement scores.
An empirical analysis of Cambodian behavior intention towards mobile payment

Article history: Received: June 12, 2019 Received in revised format: June 29 2019 Accepted: July 6, 2019 Available online: July 6, 2019 Mobile payment is becoming an evitable trend in the globe and is well expanding rapidly into emerging countries. Many research models are developed and confirmed that behavior intention is an important fact which decides the level of using mobile payment among users. The existing research models have made empirical evidences confirming behavior intention depended on performance and effort expectancy. This research expands previous empirical evidence by involving perceived transaction speed as an important explanatory variable to both performance expectancy and effort expectancy and also captures how behavior intention is influenced by performance expectancy and effort expectancy among Cambodian users. A total of 200 questionnaires were collected, analyzed and summarized for this study. Result reveals that performance expectancy and effort expectancy affect positively and significantly on behavior intention. Perceived transaction speed has a positive and significant relationship with effort expectancy but Perceived transaction does not have any positive and significant relationship with performance expectancy. Result from this study also concludes the role of perceived transaction speed which is affecting intention to use mobile payment among users. However, there are some limitations to be addressed for the future researches; this research may include larger samples to find out the clear effect on behavior intention of the end-users. © 2019 by the authors; licensee Growing Science, Canada
High-tech adjuncts to emergency weight estimation: Point-of-care ultrasound and point-of-care bioelectrical impedance measurements can increase the accuracy of length-based weight estimation in children

Introduction: An accurate and reliable method of estimating weight in sick obese children, for purposes of drug dosing calculations, has proved to be elusive. Incorporating the use of high-tech, point-of-care technology into weight-estimation methodology has not been evaluated before. We aimed to determine if ultrasound and bioelectrical impedance measurements could be used in combination with the PAWPER XL tape (PTXL) to increase the accuracy of total body weight (TBW), ideal body weight (IBW) and fat-free mass (FFM) estimation. Methods: A convenience sample of 332 children attending an academic Emergency Department was enrolled. Each child had their weight estimated with the PAWPER XL tape and underwent anthropometric, point-of-care ultrasound (PoCUS) and bioelectrical impedance (BI) measurements of parameters useful for body composition assessment. Dual X-ray absorptiometry (DXA) was measured and used as a reference for body composition. Multiple regression techniques were used to identify variables and variable-combinations that were strongly associated with TBW, IBW and DXA-measured FFM. Low-tech combinations including anthropometric measurements only were compared with models including high-tech measurements. Results: The PTXL alone, with no lowor high-tech adjunct, provided the most accurate estimate of IBW. Estimates of TBW based on anthropometric measurements were significantly improved with the addition of poCUS or BI to the prediction models, especially in underweight and obese children. Similarly, high-tech models significantly outperformed the low-tech models for estimating FFM. Conclusions: The use of PoCUS and BI significantly improved the accuracy of TBW and FFM estimation in children when compared with anthropometric-based methods.

Idiot science for a blue humanities: Shakespeare’s The Comedy of Errors and Deleuze’s mad Cogito

ABSTRACT Can we imagine a Blue Humanities that takes the non-relation as a starting point for ecological thought? I believe we can. Following Shakespeare and Deleuze, this essay engages in a thought experiment that, if it is not too absurd, might, like the ship of fools of medieval times, unmoor the Blue Humanities from its current safe harbor by putting the thought of ‘our’ world under erasure. This is not a matter of turning thought around, such that, by turning to the sea, we turn thought away from calculation and instrumental reason and rediscover our true nature. Rather, the image of thought I pursue here is narcissistic. Reading Shakespeare and Deleuze in a minor key, we will see that narcissism not only makes our relations doubtful, but also enfolds the non-relation as the very inside/outside of ecological thought.
Self-efficacy model for better job outcomes: An approach to promote female employment in turkish hotel context

The aim of this research is to develop and try a conceptual model that examines the impacts of work self efficacy (SEFF) on female frontline employees’ (FLEs) work-family conflict and perceived politics and at the same time a potential moderating role of tenure in a hospitality context in Turkey. In this research, a total number of 151 utilizable questionnaires were individually collected from a sample of full-time female FLEs in the survey premises. The proposed hypotheses were tested applying PLS-SEM. Findings, according to the hierarchical regression tests, reveal that SEFF made a significant negative influence on both work-family conflict and perceived politics. Findings also show that tenure buffers the effect of SEFF on these outcomes. This research procures implications for hotel organizations in terms of mitigating female FLEs’ work-family conflict and politics perceptions. In addition, this research ensures effective guidelines to apply potential management practices and improve job results within a hotel job context. Theoretically, this study by exploring the untested effects and relationships such as the influence of work self-efficacy on female FLEs’ workfamily conflict and politics perceptions lends further contribution to the tourism and hospitality management literature. Also, the current study carried the Conservation of Resources theory to one step further.

This work tries to do a revision to the preferences, tastes and ways of consuming television on the part of the young men of Aragon. The contributed results arise from 790 surveys realized (fulfilled) to individuals who form a part of this group. The investigation puts of manifest the notable interest that this group demonstrates for the local televisions, for the information and the entertainment and especially for the contents of proximity. All these preferences place inside a wider context in which it is revised also the models of consumption of other means (press, radio and Internet) as well as the results are analyzed having in bill public laceration of the radio and the television.
A Qualitative Investigation of Young Footballers’ Perceptions Regarding Developmental Experiences

This study examined perceptions of Greek young football players regarding sport-related developmental experiences using a model of PYD through sport based on results from a qualitative study as a theoretical framework. Twenty one young football athletes (aged 12–15) gave semi-structured interviews. The young athletes identified both positive and negative developmental experiences related to the behaviors of coaches, parents and peers. They did not report any explicit teaching of life-skills. However, young footballers identified their life-skills development by implicit processes. Nevertheless, their understanding of life-skills was rather simplistic.
Towards an evidence‐base for student wellbeing and mental health: Definitions, developmental transitions and data sets

Against a background of huge changes in the world of university and college students since the turn of the millennium, together with a multitude of reports on student mental health/wellbeing, this article argues that the field of student mental health is hampered by the imprecise use of terms, a rush to action by universities in the absence of a robust evidence‐base, and a lack of overall coordination and collaboration in the collection and use of data. In response, we argue for clearer and more consistent use of definitions of, as well as differentiations between, student wellbeing and mental health, for a longitudinal approach to the student body that captures their developmental transitions to and through university, and a strategic and systematic approach to the use of bona fide measures in the collection of data on wellbeing and on the process of outcomes in embedded university counselling services. Such a coordinated approach will provide the necessary evidence‐base upon which to develop and deliver appropriate support and interventions to underpin and enhance the quality of students’ lives and learning while at university or college.
Inclusion Complexes between Starch and Oleic Acid as Hydrogel Materials

Starch-based hydrogels are biodegradable and biocompatible materials which have large surface area and are able to absorb a large amount of water. Hydrogels can be made of inclusion complexes between starch and hydrophobic guest molecules, such as starch-oleic acid complexes. The resulting hydrogels have advantages as the inclusion complexes can prevent the starch retrogradation in the hydrogel. For this purpose, inclusion complexes between starch and oleic acid were prepared by mixing cassava starch and oleic acid at 85 °C with varying complexation times(1 hour, 2 hours and 5 hours). Optimum result (product yield ~67%) was obtained by heating the reaction for 5 hours at 85 °C. In addition, the concentrations of oleic acid for complexation were varied at 10%, 20% and 50% (v/w) (calculated based on the weight of starch). The results showed that the maximum amount of oleic acid which could be complexed with starch was around 10% (v/w). The resulting products were characterized by Fourier Transform Infra Red (FTIR) spectroscopy, X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM). FTIR results of the complexes showed vibration peaks at around 3600-3000 cm-1 (-OH), 2900-2800 cm-1 (-CH2), 1300-1200 cm-1 (C-O-C glycosidic bonds) and 1100-1000 cm-1 (C-C and C-O). The XRD results showed that the resulting complexes were crystalline and constructed of V6-amylose, which was evidenced by the appearance of peaks at 2θ of 13.06° and 20.38°. Some complexes also showed interesting diffractions at 2θ of 17.07° and 30.26°. TGA results showed that the complexes started to decompose at either around 277 °C or 285 °C compared to starch which started to decompose at around 303 °C. SEM studies showed that the resulting complexes formed spheres with concave centers close to the shape of doughnuts. The complexes offered great potential to be applied as hydrogel materials, such as round hydrogels with initial average diameters of around 2.6 mm and 8.3 mm.
Relating EFL University Students' Mindfulness and Resilience to Self-Fulfilment and Motivation in Learning.

Given the prominence of mindfulness in educational settings and the fact that little attention has been given to this concept in foreign language learning, the present study sets out to explore the influence of mindfulness and L2 resilience on Iranian EFL (English as a foreign language) learners’ self-fulfilment, and L2 motivation. To meet this objective, 221 EFL learners were recruited to participate in this study. They were asked to respond to the Langer mindfulness scale (LMS), L2 resilience inventory, measurement of actualisation of potential (MAP), and motivation scale. Afterwards, structural equation modeling (SEM) utilising the LISREL 8.50 statistical package was exploited to shed light on probable relationships. The findings demonstrated that mindfulness is a positive and consistent predictor of self-fulfilment and resilience and also exerts positive influence on L2 motivation both directly and indirectly via its effect on self-fulfilment. Resilience was positively and significantly associated with self-fulfilment. Resilience has a positive relationship with L2 motivation, both directly and indirectly via self-fulfilment. In addition, it was found that L2 motivation was predicted by self-fulfilment positively and significantly. Taken together, the pivotal role of mindfulness in language learning was demonstrated, and according to the findings, some suggestions are put forward regarding the implications of the study.
Formative Assessment of Writing (FAoW): A Confirmatory Factor Structure Study

This validation study was undertaken to evaluate the construct of Formative Assessment of Writing (FAoW) operationalized by an instrument with 50 Likert scale items. To identify the EFL learners’ experiences of FAoW practices, the instrument was first piloted with three EFL learners, and subsequently administered on a sample of 255 EFL learners selected based on purposive sampling. A five-factor solution with five latent variables (i.e. clarifying criteria, evidence on students’ current learning, feedback to move learners forward, peer-assessment and autonomy) was evaluated through Confirmatory Factor Analysis (CFA) with AMOS 22. Model fit showed that the five-factor structure of FAoW could only be supported in terms of absolute and parsimony fit indices. The model with three factors (i.e. clarifying criteria, peer-assessment and feedback) in two stages of pre- and while-writing, however, provided higher discriminant validity in addition to absolute and parsimony fit indices. In other words, FAoW was not found to be practiced within its full potential with five components in the context of this study. A conceptual model was developed based on the findings and the literature to show pedagogical application of FAoW and how it can be practiced in line with Black and Wiliam’s (2009).
Experimental Evidence for Partially Dehydrogenated ε-FeOOH

Hydrogen in hydrous minerals becomes highly mobile as it approaches the geotherm of the lower mantle. Its diffusion and transportation behaviors under high pressure are important in order to understand the crystallographic properties of hydrous minerals. However, they are difficult to characterize due to the limit of weak X-ray signals from hydrogen. In this study, we measured the volume changes of hydrous ε-FeOOH under quasi-hydrostatic and non-hydrostatic conditions. Its equation of states was set as the cap line to compare with ε-FeOOH reheated and decompression from the higher pressure pyrite-FeO2Hx phase with 0 < x < 1. We found the volumes of those re-crystallized ε-FeOOH were generally 2.2% to 2.7% lower than fully hydrogenated ε-FeOOH. Our observations indicated that ε-FeOOH transformed from pyrite-FeO2Hx may inherit the hydrogen loss that occurred at the pyrite-phase. Hydrous minerals with partial dehydrogenation like ε-FeOOHx may bring it to a shallower depth (e.g., < 1700 km) of the lower mantle.
The psychology of vehicle performance : implications for the uptake of electric vehicles

Road transport accounts for around 16% of global CO2 emissions, and electric vehicles (EVs) represent a potential mitigation route. High performance might offset the disadvantages of higher cost and short range that make their uptake problematic. This research investigated how consumer drivers construe, perceive and value vehicle performance. Research with UK drivers, using the repertory grid method, found that drivers construe vehicle performance as having two independent dimensions, dynamic and cruising performance. A new inter-goal dynamics and feedback control model of driving behaviour was developed to account for differences in the opportunities afforded to perceive vehicle performance in naturalistic driving. This was embedded in a Bayesian model for perception of available vehicle performance. Driving simulation and test track experiments with UK drivers found that: driving behaviour was strongly affected by goal activation; drivers could perceive performance differences in naturalistic driving, but only if they were large; the lowest perceptual difference threshold, for mid-range available vehicle acceleration, was 7.7%; smaller differences could affect driving behaviour (overtaking) through a process of implicit learning. The symbolic value of products is conferred by their symbolic meanings. Two new methods were developed to quantify symbolic meanings, grounded in costly signalling theory, which represents them in terms of personality traits of a typical user. The symbolic meanings of car types, performance attributes and driving styles were all measured. In a randomised controlled trial, UK consumer drivers rated an EV better on dynamic and cruising performance than a conventional ICE control, but this benefit was insufficient to outweigh the disadvantages. The symbolic meaning of an EV was found to be consistent with cruising performance, but inconsistent with dynamic performance. Extended-range EVs would have the dynamic and cruising performance benefits of EVs without the range disadvantages, and may be a desirable option for many once costs reduce.
Sexualized gender stereotypes predict girls’ academic self-efficacy and motivation across middle school

Sexualized gender stereotypes (SGS) include the belief that girls should singularly prioritize their sexualized attractiveness for the attention and approval of boys. By elementary school, boys and girls perceive girls’ sexualized attractiveness to be incompatible with intelligence and competence. In the current 2-year study, we examined whether girls’ higher SGS endorsement in seventh grade predicted a diminished mastery goal orientation and lower perceptions of academic ability in eighth grade and whether this was moderated by gender typicality and self-monitoring. Cross-lagged panel analyses tested whether earlier academic attitudes better predicted later SGS endorsement than the inverse. The study included 77 girls in the final sample from four public middle schools (MageT1 = 12.4, SD = .57). The sample was ethnically diverse (45% identified as White, 21% as Latinx, 19% as Black/African American, and 14% as multiracial). Girls’ greater endorsement of SGS in the seventh grade predicted lower academic self-efficacy later, controlling for age, academic ability, and earlier levels of academic attitudes. Highlighting a likely feedback loop, earlier academic self-efficacy equally predicted later SGS endorsement. For highly gender-typical girls, greater SGS endorsement also predicted lower mastery goal orientation over time.
Road traffic accidents, near-misses and their associated factors among commercial tricycle drivers in a Nigerian city

Tricycles form an important part of the intra-city transport system, following the ban placed on motorcycles in Maiduguri, Nigeria. However, no previous studies have been conducted to assess the occurrence of accidents among them. The objective of this study was to determine the prevalence of road accidents, near-misses, and their associated factors among commercial tricycle drivers in Maiduguri. A cross-sectional study was conducted among registered commercial tricycle drivers in Maiduguri who had been in the business for at least a year. Data was collected through face-to-face interviews, using a structured questionnaire, and was subjected to bivariate and multivariate analysis using SPSS. The prevalence of road accidents and near misses were 46% and 50.3% respectively. Only six (3.9%) of respondents who had experienced a near-miss mentioned that they occurred while they were fully awake; during clear weather; and on a smooth, broad, and non-congested road. All the others had experienced the near miss under an unfavourable weather, road, and/or while feeling sleepy. In the bivariate analysis, only psycho-active substance use (χ2=3.941; df=1; p=0.047) and having experienced more than one near miss (χ2=31.807; df=1; p<0.001) were significantly associated with having an accidents. However, in the multivariate analysis, having experienced more than one near miss was the only factor which significantly predicted having an accident (OR=2.89 95% CI: 1.64-5.09; p<0.001). There is a need to conduct further intervention studies to determine the effectiveness of intervention measures in reducing accident rates among these tricycle drivers.
How perception of local people towards rhesus macaque (Macaca mulatta) can influence on decision-making of human-macaque conflict mitigation?

A field study was conducted to investigate perception of local people towards conservation of macaques and possible mitigation strategies can be opted to reduce human-macaque conflict in urban landscape. Questionnaire survey was designed to collect qualitative and quantitative information including 608 respondents in and around Asola-Bhatti Wildlife Sanctuary, India during 2016-2017. Our study result showed that there were 21 groups of rhesus macaques available in the study area and caused severe damage to the nearby localities and harassed a total of 466 numbers of individuals. Maximum number of conflict incidences (n=502) were recorded from Sanjay Colony, Bhatti mines area, designated as Site 1 due to maximum availability of food and shelter, large troop size (35-40 individuals) and lack of knowledge of local people. Minimum number of conflict incidences (n=157) were recorded from Surajkund area, designated as Site 7 despite of having multiple food resources because of small troop size (15-20 individuals) and conservation awareness of local people. In this study, we compared socio-cultural aspect of selected locations of study area, socio-economic characteristics of two extreme respondent groups from site 1 and site 7 and also distinguished different age groups of respondents and compared their opinion on mitigation of conflict in urban situation. In the conclusion, it can be said that attitude and perception of local people can contribute in conservation of rhesus macaques and in reducing risk of negative association during conflict. Perception of local people can be helpful in decision making and policy implementation in urban monkey population management.
