Academic Performance in Distance Education: Quizzes as a Moderator Variable and Students’ Perception and Expectation through Linguistic Analysis

This study sheds light on the relation between assessment modalities and student behavior through linguistics styles, and academic performance. First, we examine the effect of assessment modalities (self-evaluation quizzes and summative quizzes) on academic performance. Using two modalities of online quizzes, we mainly focus on the student participation, student behavior (the work pacing and time management), type of assessment, and student characteristics. Second, we analyze the student behavior through linguistic styles and third, we examine the levels of anxiety and the expectation of success during the course. Specifically, we compare the linguistic styles of high performing students and low performing students and changes in anxiety levels and expectation of success. Methodologically, this study includes a static and dynamic perspective and combines quantitative analysis with a qualitative approach. The participants are students enrolled in Managerial Accounting for Tourism course in the academic year 2019–2020. The results show that both quizzes modalities are positively associated with academic performance. The linguistic analysis shows differences in the language between high performing students and low performing students. Finally, a pattern of changes on the students’ expectations of success and levels of anxiety are identified during the course.
Changing Roles of Social Work Educators in Schools for Students with Special Needs in Osun State, Nigeria

School social workers are trained health professionals who provide important services directly to students and sometimes to teachers in their institutions. They act as the connection for schools, homes and community services to help students’ educational, emotional, and developmental needs. Many of them practice in private and public schools. Not many school social educators could discharge their duties to their maximum capacity, their roles are changing in schools due to lack of necessary equipment for learners, as a result of changes in economic situation in Nigeria. The study investigated the extent the required equipment for the teaching of learners with special needs are available in their schools; the changing roles of social workers in schools; and the effects of the changing roles of social work educators on students with special needs and members of the society. The study was carried out using qualitative research approach. Structured questionnaire guided the focus group discussion. Interaction was done with social work educators in their randomly selected schools for students with special needs in Osun State, Nigeria. Findings revealed that social workers trained people with special needs to make good use of their skills to prepare materials and goods for self-development; schools used different methods to communicate and sensitise parents, and the entire community to take their children to these schools. Also, the roles of social work educators are changing as they have to source for ways of getting equipment for learners, by pleading to philanthropists or religious bodies for the provision of these equipment, as the learners’ needs could not be met either by the government or their parents. This study is contributing to the knowledge of everyone that teaching people with special needs cannot be effective without the use of instructional materials. Observations revealed apart from lack of equipment, educators’ services also faced suspicion, criticisms and neglect by some members of the society. Based on these findings, it was recommended that social work educators be not discouraged due to lack of instructional materials or equipment for the use of their students with special needs, or comments from members of the society, but take the work as a call to serve humanities in their society.
Extrapyramidal Side Effects of Intramuscular Antipsychotics in Psychosis and Substance Use Disorders , Occurrence and Predictive Factors

This retrospective study aims to determine the occurrence of extrapyramidal symptoms (EPS) after intramuscular (IM) antipsychotic treatment at emergency services and the predictive factors among acute psychotic patients with substance use disorders (SUD). We randomly selected medical records of acute psychotic patients with SUD, free of initial EPS needing IM antipsychotic drugs. The occurrence of EPS and relevant data were collected. The occurrence of EPS was 7.84 %. The proportion of patients with comorbidities, light smokers who were treated with IM haloperidol and zuclopenthixol were significantly higher in the EPS group (p = 0.009, p = 0.012 and p = 0.011) while the proportion of those with high intensity amphetamine dependence were significantly lower in the EPS group (p = 0.044). However, IM haloperidol with zuclopenthixol was the only predictive factor of EPS (OR = 13.39, p = 0.043). Our results showed a lower risk of EPS in SUD patients compared to 9.8 % in non SUD patients. It was supported by previous findings showing that substance dependence caused persistent high DA concentration after abstinence and probably a decreased risk of EPS in SUD patients. A combination of a typical antipsychotic drug and benzodiazepine is the safer alternative for nonresponsive SUD patients.
Impact of sleep apnea and treatments on cardiovascular disease

Cardiovascular diseases (CVDs) are the leading causes of mortality worldwide, accounting for nearly 18 million deaths per year. Among other considerations, treating CVDs requires better understanding their risk factors. Sleep-disordered breathing, especially obstructive sleep apnea (OSA), is a likely contributor to several CVDs. We review key epidemiological data that addresses the link between OSA and cardiovascular outcomes such as hypertension, atrial fibrillation (AF), stroke, atherosclerosis, and heart failure (HF), and proposed pathophysiological mechanisms underlying this association. There are several biological pathways linking OSA and an increased propensity to cardiovascular diseases, and we discuss the evidence on the benefits of treatments of OSA on the prevalence of cardiovascular complications.
Effect of minor loop on magnetic characteristics of permanent magnet type of MRI

A modeling technique of the minor loop using typical hysteresis loops is shown. The effect of the minor loop and eddy current in the pole piece of a permanent magnet type of MRI on the residual flux density of the probe coil is examined. It is illustrated that the change /spl Delta/B of residual flux density occurs due to the minor loop of the pole piece. It is also pointed out that the choice of time interval /spl Delta/t is important in a nonlinear analysis considering the minor loop.
Strategies of Applying Visual Element Combination to Improve Visual Cognitive Efficiency in the Era of Big Data Network

Fundamentally, visual cognition refers to a way of thinking in which the objective information of the external world is transmitted to the brain through the visual nerve and then processed by the brain. In the evolutionary history of human beings, the pressure brought by the environment has led to the rapid development of the visual system and visual cognition. As with language ability and logical ability, the understanding of visual cognition is the key to the analysis of human intelligence. Therefore, research on improving the efficiency of visual cognition is urgently needed. The purpose of this paper is to find methods and strategies to improve the efficiency of visual cognition based on the application of visual element combination. This article first gives a general introduction to visual elements and design methods. Then, the eye movement behavior and visual saliency calculation model are established. Using Gaussian analysis and channel saliency test method based on “where” and “what” principles, the cognitive effect of pictures in visual elements is specifically analyzed. Then, the questionnaire survey method was used to conduct experiments on the problem that visual elements affect the efficiency of visual cognition, and finally the results were obtained. At the macro level, dynamic pictures with color and auxiliary text can effectively improve the cognitive efficiency of vision. It enables people to grasp cognitive objects quickly and form stronger cognitive ability. However, at the micro level, due to the intuitiveness and meaning of words, the visual cognitive efficiency of the recognition effect is high. In terms of image scale, the two scale parameters [4 × 4] and [6 × 6] perform better. The human eye is relatively optimal at 4/90∼6/90 on the attention scale of the image. At the same time, under the [4 × 4] scale parameter, even if the image loses some features, it can save about 95% of the cognitive time overhead.
The Effect of Deceptive Marketing Communication on the Brand Equity of Private Higher Education Institutions (PHEIs) in the Northwest and Southwest Regions of Cameroon

The problem of falling educational standards in Cameroon has been posed severally from a purely educationist perspective. This study however goes from the premise that the liberalization of the Higher Educational Sector in the early 90s ushered in questionable capitalistic business practices by promoters of PHEIs in a bid to uphold their economic bottom lines as they would in any classical sector. This paper examines an extreme unethical mercantilist practice of deceptive marketing communication and its consequences on the brand equity of PHEIs in the Northwest and Southwest Regions of Cameroon. The study is cross-sectional with an exploratory approach. The study largely exploits primary data from alumni of fifteen (15) PHEIs. To mitigate for circumstantial time-bias in predictors, the researchers adopted stratified purposive and exponential non-discriminative snowball sampling. Six hundred (600) questionnaires were issued through the targeted population. For analysis, a Logit Model was applied and the simplified parameters for the various were obtained with the aid of the SPSS 16.0 software. The findings revealed a strong association between deceptive marketing communication and brand equity as it observed that, X2 (5,600) = 139.3 and highly significant (p-value of 0.0001). This was further confirmed by an insignificant Hosmer and Lemeshow Test statistic of 11.7 with a probability value of 0.165. The researchers recommend a review of regulations governing the Private Higher Education sector in Cameroon in terms of mentorship by state universities such that mentorship responsibilities include general operational and marketing supervision and not just pure academic supervision.
Gouy-Stodola Theorem as a variational principle for open systems

The recent researches in non equilibrium and far from equilibrium systems have been proved to be useful for their applications in different disciplines and many subjects. A general principle to approach all these phenomena with a unique method of analysis is required in science and engineering: a variational principle would have this fundamental role. Here, the Gouy-Stodola theorem is proposed to be this general variational principle, both proving that it satisfies the above requirements and relating it to a statistical results on entropy production.

Trends in Adolescent Health Risk Behaviors and Wellbeing: A 10 Year Observation from the EDIT Surveillance of Tuscany Region, Italy

Background: The aim of this study was to evaluate the trends of prevalence of health risk behaviors (HRBs) and health conditions over a 10 year period (2008–2018) in a representative sample of adolescents of Tuscany Region, Italy. Methods: This was a repeated cross-sectional (four survey waves) study. The prevalence of 17 HRBs and health conditions were analyzed by age, sex, and socioeconomic status (SES). Results: A total of 21,943 students were surveyed. During the study period, decreases in smoking participation, cocaine use, driving under the influence of alcohol and drugs, and problem gambling were observed, while alcohol abuse and at-risk sexual behaviors remained unchanged or increased. Males resulted more frequently involved in most of the HRBs, while females more frequently reported physical inactivity, regular smoking, and not using a condom. Female participation in smoking and alcohol abuse behaviors, fruit and vegetable consumption, and bullying worsened over the study period. Smoking, poor dietary habits, physical inactivity, high distress level, and obesity were more frequently observed in low-SES students than in high-SES students. Conclusions: The findings showed different tendencies in adolescent participation in HRBs over the last decade; concerning trends in at-risk sexual behaviors and alcohol consumption and females’ risk-taking behavior on the rise require careful monitoring.
Non-family Executives in Family Businesses : a Literature Review

The role of non-family executives in family businesses is under-researched in comparison with its importance. Reviewing the existing literature serves as a startingpoint for promoting future research. Based on a literature analysis, we develop a model for the interaction process between a family owner and a non-family executive. The main contributions for the non-family executive in family business literature are presented and structured following this interaction process. Finally, potential and unanswered questions help determine directions of future research.
The Comparison of the Treatment Outcomes of Transobturator Tape and Anterior Colporraphy in Stress Urinary Incontinence

Introduction: Stress urinary incontinence (SUI) in women had high prevalence and has a negative impact on their quality of life. Surgery is the most effective way to treat this problem. So, this study designed to compare the efficacy of transobturator tape (TOT) versus anterior colporraphy (APR) in stress incontinence patients. Methods: We designed a prospective cohort study. On base of inclusion and exclusion criteria, we had 65 patients (33 patients in TOT group, 32 patients in APR group) were randomly enrolled in this study. Patients data before surgery, 2 months, 6 months and 18 months after surgery were collected and asked them to complete incontinence quality of life questionnaires (IQOL). We used SPSS 18 for data analysis. Results: Mean surgery time in TOT group was significantly less than APR group (P<0.0001). Quality of life at 6 and 18 months after surgery was significantly better in TOT group (P<0.05). Number of incontinence patients at 2, 6 and 18 months after surgery (P<0.01), incontinence during activity at 18 months after surgery (P=0.031), severity of urinary incontinence at 6 months and 18 months after surgery (P<0.001) were significantly lower in TOT group. Complications after surgery was not different between 2 groups (P=0.78). However, 21 cases in TOT group (63.6%) and 9 cases in APR group (28.1%) complained of pain after surgery (P=0.004). The mean of hospitalization was not statistically significant difference (P=0.54). Finally, 23 patients in TOT group (63.9%) and 13 patients in APR group (36.1%) had urinary incontinence within one last month (OR:3.36, 95%, CL: 1,20-9.36, P=0.018). Furthermore, 25 patients in TOT group (61%) and 16 patients in APR group (39%) had more than 90% improvement in their quality of life (OR: 3.12, 95% CL: 1.08-8.97, P=0.031). Conclusion: The results of this study showed that the TOT techniques more efficient than the APR technique. This technique has more success rate, higher satisfaction of patients and can significantly improve patient's quality of life.
Nonlinear Differential Equations and Applications NoDEA Propagation of Gabor singularities for semilinear Schrödinger equations

We study the propagation of singularities for semilinear Schrödinger equations with quadratic Hamiltonians, in particular for the semilinear harmonic oscillator. We show that the propagation still occurs along the flow of the Hamiltonian field, but for Sobolev regularities in a certain range, in terms of a suitable definition of the global Sobolev-wave front set.

Assessing the effectiveness of a problem-based learning compared to a traditional learning methodology

Traditional learning (TL) approaches often do not prepare students well for real-world settings. This under-desired performance was often attributed to the emphasis on memorization of fragmented knowledge. The problem is particularly evident in traditional health science education where students’ often show unsatisfactory clinical performances. To overcome this problem, problembased learning (PBL) was conceived and implemented as an instructional method. It requires students to solve problems, aiming to enhance these learning outcomes by promoting their abilities and skills in applying knowledge, solving problems, practicing higher order thinking, and selfdirecting their own learning. From medical and health science education, for which PBL was initially developed as an instructional method, it has been widely adopted by various other disciplines (such as management education, biology or biochemistry, physics; cf. Bonney, 2015; Culpin & Scott, 2011; Nair, Shah, Seth, Pandit & Shah, 2013; Rayner, 2005). Case-based learning (CBL) is often used synonymously and bases learning activities in health professional education around patient cases. To our knowledge, the current study is the first publicly available report of an application of the method in pharmacy.
Quantification of Aerodynamic Variables Using Analytical Technique and Computational Fluid Dynamics

Abstract—Aerodynamic stability coefficients are necessary to be known before any unmanned aircraft flight is performed. This requires expertise on aerodynamics and stability control of the aircraft. To enable efficacious performance of aircraft requires that a well-defined flight path and aerodynamics should be defined beforehand. This paper presents a study on the aerodynamics of an unmanned aero vehicle (UAV) during flight conditions. Current research holds comparative studies of different parameters for flight aerodynamic, measured using two different open source analytical software programs. These software packages are DATCOM and XLRF5, which help in depicting the flight aerodynamic variables. Computational fluid dynamics (CFD) was also used to perform aerodynamic analysis for which Star CCM+ was used. Output trends of the study demonstrate high accuracies between the two software programs with that of CFD. It can be seen that the Coefficient of Lift (CL) obtained from DATCOM and XFLR is similar to CL of CFD simulation. In the similar manner, other potential aerodynamic stability parameters obtained from analytical software are in good agreement with CFD.
High-pressure garnet amphibolite from the Funaokayama unit, western Kii Peninsula and the extent of eclogite facies metamorphism in the Sanbagawa belt

Quantitative analyses of garnet-bearing epidote amphibolite (hereafter garnet amphibolite) from the Funaokayama unit, western Kii Peninsula of the Sanbagawa belt reveal a previously unrecognized high-grade part of the Sanbagawa metamorphism. Petrographic observations suggest that the garnet amphibolite underwent three stages of metamorphism (M1, M2 and M3). Records of M1 are preserved as syn-tectonic prograde-zoned garnet and its inclusions. Pseudosection modeling reproduces the observed M1 assemblage garnet + amphibolite + epidote + phengite + quartz and the growth zoning of garnet records the pressure (P)-temperature (T) evolution from 0.8 GPa, 570 °C to 1.3 GPa, 590 °C. Therefore, this garnet growth and associated deformation (D1) took place during subduction up to eclogite facies conditions. The garnet rim compositions and inclusions of epidote, titanite, rutile and quartz (5titanite + 2clinozoisite = 5rutile + 3grossular + 2quartz + H2O) give consistent peakP estimates of 1.3-1.9 GPa. The garnet contains quartz inclusions retaining residual pressures of up to ~ 0.7 GPa, which is as high as the values reported in well-characterized eclogite samples in central Shikoku. The inferred peak-P conditions in the eclogite facies is further supported by the occurrence of aragonite in associated pelitic schist. The assemblage hornblende + epidote + titanite + quartz + albite in the matrix and its equilibrium conditions of ~ 0.8 GPa, 580 °C suggest decompression to the epidote-amphibolite facies (M2). The M2 minerals locally show replacement by the mineral assemblage actinolite + epidote + chlorite + titanite + calcite + quartz + albite, suggesting a partial re-equilibration in the greenschist facies (M3). M2 and M3 are synchronous with the main phase of ductile deformation during exhumation (D2). Despite the absence of the omphacite + quartz assemblage, it is likely that eclogite facies metamorphism in the Sanbagawa belt can be extended to western Kii Peninsula.
Potential antecedents and outcomes of frontline employees’ service recovery performance

Frontline employees frequently act as a bridge between a firm and its customers. Therefore, customers often form their opinions on service quality of the firm based on how well the frontline employees perform. This conceptual paper intends to explore some potential antecedents that might have an impact with particular regard to frontline employees’ service recovery performance. In addition, it also looks at its potential impact on selected outcomes. Using the existing literature, hypotheses are formulated to provide understanding of the relationships between service recovery performance antecedents and its associated outcomes. This would assist managers in identifying and managing the factors, and thus will contribute towards creating a loyal base of satisfied customers. Implications for managerial actions and future research avenues are discussed. Empirical support is obviously needed for the proposed conceptual framework and therefore it has been planned for it to be tested in a hotel environment. An important reason for the hotel industry to be chosen is because of the booming of the tourism industry where the hotel sector is seen as the biggest contributor.
Veriﬁable Auditing of Access to Conﬁdential Data

The sharing of personal data has the potential to bring substantial beneﬁts both to individuals and society, but only if people have conﬁdence that their data will not be used in-appropriately. As more sensitive data is considered for sharing (e.g., communication records and medical records) and used to make important decisions, there is a growing need for transparency in the way that the data is processed, while protecting the privacy of individuals and the integrity of their data. We propose a system, VAMS, which allows individuals to check accesses to their personal data, and enables au-ditors to detect violations of policy. Furthermore, our sys-tem protects the privacy of individuals and organizations, while allowing published statistics to be publicly veriﬁed. We demonstrate the practicality of our system with two pro-totypes, based Hyperledger Fabric and Trillian.
