Digital Games and the Teaching and Learning of Mathematics: A Survey Study

ABSTRACT There is strong theoretical and empirical support for the use of digital games for learning. Despite their research support, digital games are not widely used in mathematics classrooms. One main contributor to this lack of adoption is the paucity of extant research on the extent to which mathematics teachers are using digital games, how teachers are using digital games in the mathematics classroom, and what barriers hinder their use of digital games. To begin answering these questions, the Digital Game Usage in the Mathematics Classroom Survey was developed. Pilot data were collected to evaluate the reliability and validity of the survey. The results of the pilot study are discussed along with recommendations for future research and survey instrument usage.

This showed that there was a significant effect of using the REACT strategy assisted by GeoGebra software on students' mathematical representation ability.
Multilevel dynamic voltage restorer

This paper presents the implementation and control of a high voltage dynamic voltage restorer (HVDVR) for use in power distribution network to compensate for sags in utility voltages. The proposed HVDVR is implemented using a multilevel inverter topology with isolated DC energy storages, allowing the direct connection of the HVDVR to the distribution network without using a bulky and costly series injection transformer. A novel control algorithm, incorporating P+resonant and Posicast compensators, is also presented for controlling the HVDVR with perfect reference voltage tracking and effective damping of transient voltage oscillations at the instant of sag compensation. Lastly, simulation results are presented to verify the performance of the proposed multilevel HVDVR.
Impacts of Bias‐Corrected ERA5 Initial Snow Depth on Dynamical Downscaling Simulations for the Tibetan Plateau

The Tibetan Plateau (TP) is often called the “Water Tower of Asia,” which contains the largest amount of snow and glaciers outside the polar regions. As an important and variable feature of the land surface, snow coverage on the TP has great impacts on regional climate. However, the commonly used ERA5 reanalysis in dynamical downscaling largely overestimates the snow depth for the TP. To improve the representation of snow cover in ERA5, a new ERA5‐driven downscaling data set (High Asia Refined analysis version 2, HAR v2) was generated by the Weather Research and Forecasting (WRF) model with the bias‐corrected snow depth. This study aims to identify and better understand the impact of bias‐corrected initial snow conditions on simulated regional climate, by comparing the HAR v2 with a 5‐year ERA5 forced WRF simulation without bias correction of initial snow depth (referred to as WRF_ERA5). The results show that the bias correction significantly improves the simulation of 2 m air temperature (T2), with regional mean cold bias reduced by 0.2°C–2.4°C, but no significant improvement in precipitation simulation is found. Further comparative analysis reveals that higher snow depth in WRF_ERA5 leads to T2, mean daily precipitation, summer extreme precipitation, and contributions of convective precipitation to summer mean daily precipitation decrease by 0°C–4°C, 0%–60%, 0%–40%, and 0%–10%, respectively, in most areas of the TP. In addition, the bias‐corrected initial snow depth also has impacts on simulated diurnal cycles of precipitation and T2 and leads to peak hours one hour earlier. Overall, this study confirms the importance of snow cover for the climate in the TP.
Virtual contact hypothesis: Preliminary evidence for intergroup contact hypothesis in interactions with characters in video games

This paper examines intergroup contact hypothesis in interactions in video games to conceptualize how intergroup contact with characters in games may relate to attitudes toward minorities. Intergroup contact hypothesis states that intergroup contact leads to more positive attitudes and stereotype reduction. It also specifies situational factors that promote or hinder such an outcome. In an online survey a sample of 1627 gamers stated games they played the most and filled out a questionnaire measuring their attitudes toward minorities. Independent judges assessed games that were played by most participants (N = 44 games). A multilevel regression analysis revealed that average quality of contact with minorities in a game (measured at game-level, as a characteristic of a game) was associated with higher acceptance of minorities of the players (measured at individual level). Diversity of the game world generated by fictional races had no significant connection to attitudes. Game-level predictors largely increased fit to the data showing that game worlds were significant for the acceptance of minorities. The results supply preliminary evidence for the validity of the intergroup contact hypothesis for the interactions with characters in video games.
Estimating nocturnal stroke onset times by magnetic resonance imaging in the WAKE-UP trial

Background Fluid-attenuated inversion recovery (FLAIR) sequences have gained a role to guide treatment of patients with unknown time of stroke symptom onset. Evolution of signal intensities in FLAIR is associated with time since stroke onset with continuous linear increases. Aims Estimating symptom onset during night-sleep in patients from the WAKE-UP trial based on relative signal intensities FLAIR (FLAIR-rSI) from acute stroke lesions an independent dataset (PRE-FLAIR study). Methods FLAIR-rSI was quantified in stroke lesions in PRE-FLAIR and WAKE-UP. The PRE-FLAIR study was a multicenter observational trial establishing FLAIR as a surrogate parameter for time since stroke onset. WAKE-UP was a randomized controlled trial that revealed a benefit for alteplase in patients selected based on a DWI-FLAIR mismatch. Stroke onset times were recorded in PRE-FLAIR and used to fit a linear regression model with FLAIR-rSI, adjusted for patient age and lesion volume. The model was applied to FLAIR-rSI of stroke lesions to estimate onset times in those patients enrolled in WAKE-UP who had symptom onset during night-sleep. Results FLAIR-rSI was quantified in 399 patients from PRE-FLAIR. Linear regression indicated a significant association of age (p = 0.001), lesion volume (p = 0.005) and FLAIR-rSI (p < 0.001) with time since symptom onset (adjusted R2 = 0.179). In 813 patients from WAKE-UP, distribution of times of last seen well, symptom recognition and MRI examination were recorded. Median times of last seen well were 1 h before midnight (IQR 2.4 h) and symptom recognition 7 h after midnight (IRQ 2.2 h). Based on the FLAIR-rSI profiles, we estimated median stroke onset 6.1 h after midnight (IQR 2.7 h). Conclusion Nocturnal strokes during night-sleep may predominantly occur during the early morning hours. Our results are in line with evidence of characteristic diurnal patterns of cardiovascular events.
An Investigation on the Effects of Flow State on Team Process and Outcomes

There has been an abundance of research on flow state at the individual level and it is often applied to experiences that are typically intended to be enjoyable (e.g., video games and sports). Research has shown that flow state can also be experienced in traditional work environments and several antecedents to its achievement in such environments have been identified. Despite this, there remains some ambiguity regarding the applicability of flow state to teams. Additionally, the majority of the research regarding the experience of flow state in teams revolves around athletic teams. In this paper an argument is presented towards the view that the effect of flow state on team performance is similar to the effect of flow state on individuals but with an additional impact on team processes. The experiment conducted yielded results suggesting a linkage between team flow state and team processes and performance for a complex planning task.
Results of Radiation Therapy as Local Ablative Therapy for Oligometastatic Non-Small Cell Lung Cancer

Simple Summary Metastatic lung cancer represents a heterogeneous population of patients. Up to half of patients with metastatic lung cancer may be oligometastatic, an intermediate step between localized disease and widespread metastasis that is characterized by a limited number of metastatic deposits. Patients with oligometastatic lung cancer may benefit from local ablative therapy (LAT) directed at metastatic deposits in addition to standard-of-care systemic therapy. Radiation therapy is one option for LAT in lung cancer. This review will discuss the studies that have established the safety and efficacy of radiation therapy for oligometastatic lung cancer. Abstract Oligometastatic cancer is characterized by a limited number of metastatic deposits. Compared with lung cancer patients who have more widespread disease, oligometastatic lung cancer patients have more favorable survival outcomes. Therefore, it has been hypothesized that local ablative therapy (LAT) directed at the metastatic deposits in addition to standard-of-care systemic therapy may further improve survival outcomes in oligometastatic lung cancer patients. One LAT modality that has been utilized in oligometastatic lung cancer is radiation therapy. In particular, ultra-hypofractionated radiotherapy, also known as stereotactic body radiotherapy (SBRT), has been shown to provide excellent local control with a favorable safety profile. Here, we reviewed the retrospective studies and prospective trials that have deployed radiation therapy as LAT in oligometastatic lung cancer, including randomized studies showing benefits for progression-free survival and overall survival with the addition of LAT. We also discuss the impact of targeted therapies and immunotherapy on radiation as LAT.
A Solution to Design Semi-static Null Convention Logic Cell Libraries

The Null Convention Logic (NCL) based asynchronous circuits have eliminated the disadvantages of the synchronous circuits, including noise, glitches, clock skew, power, and electromagnetic interference. However, using NCL based asynchronous designs was not easy for students and researchers because of the lack of standard NCL cell libraries. This paper proposes a solution to design a semi-static NCL cell library used to synthesize NCL based asynchronous designs. This solution will help researchers save time and effort to approach a new method. In this work, NCL cells are designed based on the Process Design Kit 45nm technology. They are simulated at the different corners with the Ocean script and Electronic Design Automation (EDA) environment to extract the timing models and the power models. These models are used to generate a *. lib file, which is converted to a *. db file by the Design Compiler tool to form a complete library of 27 cells. In addition, we synthesize the NCL based full adders to illustrate the success of the proposed library and compare our synthesis results with the results of the other authors. The comparison results indicate that power and delay are improved significantly.

GENERALIZED KRONECKER ARRAY TRANSFORM

Fast evaluation of the array response matrix and its vector or matrix products play a central role in several applied electromagnetics and array processing applications. In this context, the Kronecker Array Transform (KAT) has been introduced by Ribeiro and Nascimento as an efficient factorization technique that can be applied when the elements of a planar array and the wavevectors exhibit separability. The computational savings leverage on the decomposition of the full array response matrix in the Kronecker product of two smaller array response matrices. In this contribution we extend and apply the generalized Kronecker product introduced by Fino and Algazi to the array response matrix decomposition problem. The resulting Generalized Kronecker Array Transform (GKAT) broadens the class of problems that can be addressed while achieving the same computational savings. The complexity of GKAT is compared with Non-Uniform Fast Fourier Transform (NUFFT), and optimal integration of the two techniques is elaborated.
Performance of a Bioretention Area and a Level Spreader-Grass Filter Strip at Two Highway Sites in North Carolina

The pollutant removal efficiency of a bioretention area and a level spreader-grass filter strip implemented at North Carolina highway facilities was assessed. The assessment consisted of monitoring inflow, outflow, and on-site rainfall for at least 13 storm events. Monitoring included continuous discharge measurement and collecting and analyzing flow-proportional samples for each event. All samples were analyzed for solids, turbidity, and nitrogen and phosphorus forms and selected samples were analyzed for metals. The level spreader-grass filter strip had the best overall efficiency with load reduction efficiencies in all pollutants ranging from 24 to 83% and the highest reduction for total suspended solids (TSS). Much of the efficiency of this best management practice can be attributed to the 49% reduction in runoff volume from inflow to outflow. Pollutant reduction efficiencies for the bioretention area ranged from −254 to 76% with the highest reduction for TSS. The lowest or large negative efficiency w.
Full-wave analysis of dielectric waveguides using tangential vector finite elements

A novel method is presented for the analysis of dielectric waveguides. This method provides four major new contributions: (1) a transformation of variables is introduced that allows propagation constants to be computed directly; (2) H/sub 1/ (curl) tangential vector finite elements are applied to dielectric waveguides to obtain reliable approximate electromagnetic fields; (3) the Lanczos algorithm is modified to solve the required eigenmatrix equation efficiently; and (4) the reaction principle is used to provide a posteriori error estimates for use in adaptive mesh refinement. The method produces reliable solutions and applies to structures that contain both electric and magnetic inhomogeneities. The answers are refined adaptively to generate waveguide eigenmodes to a specified accuracy. Numerical results of an image guide, a microstrip transmission line, and a pedestal-supported stripline are shown. Computed solutions agree very well with previously published results. >

According to result of this research; Averaged united years, the highest seed yield (399 kg ha -1 ),essential oil content (% 2.67) and essential oil yield (10.6 kg ha -1 ) were obtained from the 40 kg ha -1 P 2O5 application.
Causes of death following discharge after trauma in North Carolina

Supplemental digital content is available in the text. BACKGROUND While a “fourth peak” of delayed trauma mortality has been described, limited data describe the causes of death (CODs) for patients in the years following an injury. This study investigates the difference in COD statewide for patients with and without a recent trauma admission. METHODS This retrospective cohort study compared COD for trauma and nontrauma patients in North Carolina. Death certificates in NC's death registry were matched with the NC trauma registry between January 2013 and December 2018 using matching on name and date of birth. Patients who died during the index trauma admission were excluded. Underlying COD recorded on the death certificate were used for the primary analysis. RESULTS Of 481,415 death records, 19,083 (4.0%) were linked to an alive discharge within the trauma registry during the study period. Prior trauma patients (PTPs) had a higher incidence of mental illness (9.2 vs. 6.1%), Alzheimer's (6.1% vs. 4.2%), and opioid-related (1.8% vs. 1.6%) COD compared to nontrauma patients, p < 0.05. Overall, suicide was higher in the nontrauma cohort (1.5% vs. 1.1%); however, PTP had higher incidences of death by motor vehicle collision and other injury (6.0% vs. 3.8%) and homicide (0.9% vs. 0.6%), p < 0.001. Prior trauma patients had 1.16 increased odds of an opioid-related death (p = 0.009; 95% confidence interval, 1.04–1.29) compared with those without prior trauma. Younger PTP had a much higher rate of death from suicide (12.0%) compared with those 41 to 65 years (2.8%) and older than 65 years (0.2%; p < 0.001). Discharge to skilled nursing facility (odds ratio, 1.87; p < 0.05) and severe injury (odds ratio, 1.93; p < 0.05) were associated with early death after discharge (≤90 days). CONCLUSION After hospital discharge, PTPs remain at risk of dying from future trauma and opioid-related conditions. Prevention strategies for PTP should address the increased risk of death from a subsequent traumatic injury and the at-risk populations for early death after discharge. LEVEL OF EVIDENCE Prognostic and Epidemiologic, Level IV.
Mobile banking adoption and usage among Generation Y Malaysians

Background: By 2018, Malaysian mobile banking services made the third-largest amount of banking transactions, following credit card and Internet banking. In addition, it significantly contributes to the banking industry by providing easier transactions to banking consumers. This study examined factors affecting the intention to use, and the actual use of mobile banking services in Malaysia. Methods: Two main theories of the unified theory of acceptance and use of technology (extended version, UTAUT2), and the model of perceived risk, were used to propose a modified framework. Based on the non-probability sampling method, the data were collected from 504 respondents. The data vas analyzed using SPSS and PLS-SEM to derive the findings. Results: The study's findings revealed that the independent variables could explain 55.3% of the variance in mobile banking use and 60.3% of variance in intention to use variables. Moreover, it demonstrated that common factors that have significantly affected the actual use and intention to use mobile banking were habit, facilitating condition, and interface design quality. In contrast, perceived risk and intention to use were found to only have significant impacts on the use of mobile banking, while effort expectancy was found to only have a significant impact on the intention to use. Conclusions: The findings of this study provide significant new knowledge on mobile banking, from which mobile banking providers and interface designers can develop potential solutions to increase the usage of mobile banking services in Malaysia. However, using a qualitative method, the proposed model could only explain 55% of actual use and 60% of intentional use. Thus, additional variables and qualitative techniques may help increase the understanding on the actual use and intention to use.
Studies on Postnatal Development of Testis of Guinea Pig (Cavia porcellus)

The histology and histochemistry of the testis of guinea pig of various postnatal age groups was conducted. A total of 24 guinea pigs of four different postnatal ages with six male animals each were collected from the Department of Laboratory Animal Medicine, Madhavaram Milk Colony, Chennai as per the Ethical committee approval. After collection, animals were euthanized as per CPCSEA norms and testis was dissected out and was cut into small pieces, fixed and processed for paraffin embedding. Sections of 4–5 µm thickness were cut and used for the routine and special histological and histochemical staining techniques. Testes wereencapsulated by tunica vaginalis and tunica albuginea. Septa from the capsule divided the testicular parenchyma into lobules. Each lobule consisted of seminiferous tubules which consisted of spermatogenic cells in stratified layers and sertoli cells. Pre-weaning and weaning group of guinea pigs seminiferous tubules showed wide lumen with only type 1 and type 2 spermatogonia and sertoli cells. Young and adult animals seminiferous tubules showed narrow lumen with type 1 and type 2 spermatogonia, primary spermatocytes in various stages of differentiation, secondary spermatocytes, spermatids (early and late) and sertoli cells. Sertoli cells were large oval shaped cells with lightly stained irregular shaped nucleus. Interstitial tissue contained leydig cells in all ages.Leydig cells appeared as varied in shape. In all the age groups studied, PAS activity was noticed in the capsule and basement membrane. The micrometrical parameters increased as age advanced in both right and left testis.
