Don't Assess a Fish by Its Ability to Climb a Tree
Authors: Kouo Jennifer L.
Published: September 2021

The heterogeneity of students in today's classrooms present many obstacles when it comes to formatively assessing learning. The formative assessment cycle affords teachers numerous opportunities to measure student progress towards objectives, provide timely feedback, and make necessary adjustments to instruction. Formative assessments also provide considerable value to students, in the form of learning engagement, and tracking their own progress and planning of future steps. Due to the value of formative assessments in making decisions and supporting students, it is necessary that educators plan and utilize equitable assessment practices to eliminate unnecessary barriers students may face. The chapter will therefore discuss the obstacles that variable learners may experience that impede their inclusion in classrooms, the importance of the universal design for learning in ensuring engagement and multiple means of action and expression, and finally, bring awareness to students with disabilities and the importance of accommodations and modifications in their success.

Five main categories of studies were identified, namely (1) emotional regulation, (2) communication skills, (3) academic performance, (4) social inclusion, and (5) challenging behavior. Results were fairly positive, although occasional failures occurred. Clinical, educational, psychological, and rehabilitative implications of the findings were critically discussed. Some useful guidelines for future research and practice were highlighted.
Disability Issues, Aging, and Preventive Measures
Authors: Kori Ashok , Bajantri Manjunath R.
Published: September 2021

As we know, aging is an ongoing biological process from which no human being can escape. Although everyone is familiar with ageing, defining it is not so easy. There is no United Nations standard numerical criterion of old age, but, it is agreed cut off is 60 plus years. Currently, due to the availability and accessibility of effective medication and treatment at specialty hospitals that increase life expectancy of old age people, over the past century, the population, although aged with disabilities, has aged around the world. Recent advances in the field of medicine, public health, technology, and rehabilitation in different streams have reduced the discrepancy in life expectancy for persons with disabilities.
Responding to the Needs of Prisoners with Learning Difficulties in Australia
Authors: Skues Jason , Pfeifer Jeffrey , Oliva Alfie , Wise Lisa
Published: September 2021

Offenders who are convicted of a crime in Australia are encouraged to participate in educational and vocational training programs during their time in prison. However, one of the significant challenges encountered by not only prisoners who enroll in educational and vocational training programs, but also for the staff who teach into these programs, are prisoners who experience learning difficulties. Prison teachers and other staff are ordinarily unaware of which offenders experience such difficulties. Given that unidentified learning difficulties are associated with poor educational, employment and psychological outcomes, it is critical that prisoners who experience specific learning difficulties are identified, and that educational and vocational training programs offered in prisons cater for the diverse learning needs of all prisoners. This review highlights issues with the identification of learning difficulties and proposes methods of supporting prisoners who experience learning difficulties and the people tasked with managing them. Such a review offers an important contribution to the literature on educational and vocational training programs in prisons as well as practical implications for prisoners, teachers and administrators.
Obstacles for Students With Disabilities in the Supervision Process at Postgraduate Level in South Africa
Authors: Ndlovu Sibonokuhle
Published: September 2021

The chapter presents the obstacles in supervision for students with disabilities at post-graduate level in South African higher education. Data were collected through scanning South African and international literature available on Google scholar, ProQuest, in books, journal articles, and online resources. Decolonial theory informed understanding of why the obstacles are confronted by the particular students. The findings revealed limited supervision is the main obstacle. The argument for the chapter is that students with disabilities' obstacles in supervision are far deeper than those seen at surface level.
School Bullying Among Students With Intellectual Disabilities
Authors: Wright Michelle F.
Published: September 2021

School bullying research began in the 1970s through seminal research conducted on these experiences among Norwegian boys. From this initial research, multiple studies have been conducted over the past 40 years, revealing the nature, extent, causes, and consequences of school bullying. More recent investigations have also focused on cyberbullying, bullying using information and communication technologies (e.g., cell phones). Little attention has been given to school bullying involvement among students with disabilities, particularly those with intellectual disabilities. The handful of studies on this topic suggest that these students experience internalizing (e.g., depression, anxiety, loneliness) and externalizing (e.g., aggression, antisocial behaviors) difficulties associated with their involvement in school bullying. The aim of this chapter is to review multidisciplinary research concerning school bullying among students with intellectual disabilities and to make recommendations for public policy and prevention programs as well as future research.
Practice From Implementing Web 2.0 Tools in Higher Education
Authors: Isaias Pedro , Miranda Paula , Pífano Sara
Published: September 2021

Each new technology, tool, or resource that is introduced in higher education practice with the promise of enhancing the students' learning experience and/or increasing their academic performance is subjected to meticulous scrutiny. In the early days of Web 2.0's implementation in the context of higher education, many educators expressed their concerns and were reluctant to embrace it. As it slowly proved its pedagogical value and an increasingly higher number of teachers began to incorporate it in their teaching practice and courses, the body of evidence speaking to its advantages increased and offered other educators the confidence and proof they required to do the same. This chapter examines Web 2.0 in the context of higher education by debating both its benefits and shortcomings and presenting cases of actual implementation. The cases in question pertain to the use of YouTube, Wikis, and Twitter as valuable resources in the development of different types of skills and to support the acquisition of knowledge.

Adoption of Libra as a Digital Currency in Thailand
Authors: Kraiwanit​ Tanpat​ , Limsakul Anun
Published: September 2021

Libra, Facebook's cryptocurrency, is expected to have an impact on the global monetary system; therefore, it is interesting to investigate Libra's adoption in Thailand. The objectives of this research are to examine the key factors in the acceptance of Libra and to gain an understanding of Libra. Logistic regression analysis was used for data analysis. The results indicate that Libra coins have not been accepted among Thais yet. Factors in influencing the acceptance of Libra are age, career, saving, social media, and knowledge scores. To encourage the adoption of Libra, the chapter suggests that gaining knowledge about cryptocurrency nationwide should be prioritised. Moreover, financial institutions should encourage the usage of cryptocurrency among low-saving clients and small enterprises as these groups tend to accept Libra rather than those with a large amount of savings. If cryptocurrencies are accepted nationwide, it might attract investors and boost Thai economic growth.
How Do Financial Constraints and Financial Crises Matter in Cash Management?
Authors: Tekin Hasan
Published: September 2021

This chapter investigates how financial constraints and financial crises affect the cash policy of firms. Using a sample of 157,505 firm-years from 26 developing Asian economies from 1991 to 2016, firm fixed effects are employed to mitigate unobserved heterogeneity. Empirical findings show that financially constrained firms have higher cash than financially unconstrained firms, which is in line with the precautionary motive and transaction motive of cash. The picture changes with the rise of financial crises. While financially constrained firms have lower cash before the 1997-1998 Asian financial crisis, they increase their cash level more after the 2008-2009 global financial crisis. Overall, managers need to consider the exogenous shocks to enhance their liquidity management. Also, investors should consider the financial crises, firm size, firm constraint, and dividend payment status when determining when and where to invest.

Authors: Polat Üzümcü Tülay , Alyakut Ömür
Published: September 2021

In today's world, digitalisation, as a process that results from the adoption of digital technologies and application systems built on those technologies, holds an important place in business functions and processes. Digitalisation is considered to be the engine of transformation and has significantly affected the tourism industry. China, one of the leading countries of digitalisation, launched the ‘New Silk Road Project' to revive the Silk Road, which is of great historical importance from an economic, cultural, and political point of view. Since the New Silk Road Project planned for the improvement of land and railway routes connecting China to Europe through Central Asia is of critical importance for countries along the road, it will also contribute to the revival of Silk Road tourism. This type of tourism is instrumental in protecting and preserving cultural heritage values located across the Silk Road and thus can be given a new perspective with opportunities brought by digitalisation. This study sought to discuss the reconstruction of Silk Road Tourism through digitalization.
Object Tracking Based on Global Context Attention
Authors: Wang Yucheng , Chen Xi , Mao Zhongjie , Yan Jia
Published: September 2021

Previous research has shown that tracking algorithms cannot capture long-distance information and lead to the loss of the object when the object was deformed, the illumination changed, and the background was disturbed by similar objects. To remedy this, this article proposes an object-tracking method by introducing the Global Context attention module into the Multi-Domain Network (MDNet) tracker. This method can learn the robust feature representation of the object through the Global Context attention module to better distinguish the background from the object in the presence of interference factors. Extensive experiments on OTB2013, OTB2015, and UAV20L datasets show that the proposed method is significantly improved compared with MDNet and has competitive performance compared with more mainstream tracking algorithms. At the same time, the method proposed in this article achieves better results when the video sequence contains object deformation, illumination change, and background interference with similar objects.

Authors: Dykstra Rachel , Koutakis Panagiotis , Hanson Nicholas
Published: September 2021

eSports gaming requires quick and accurate reactions in response to complex visual stimuli for optimal performance. The purpose of this study was to examine the relationship between components of physical fitness and reaction time (RT) in eSports gamers. 27 eSports gamers participated. Visit 1 included physical fitness assessments. Visit 2 included a familiarization with the Stroop Task. During Visit 3, subjects completed the Stroop Task again; data from this visit was used for analyses. For congruent, incongruent and control trials, an inverse efficiency score (IES) was calculated. Pearson correlations were used to determine the relationship between components of physical fitness and mean RT. There was a significant correlation between mean RT and cardiorespiratory fitness (r=-.338, p=.043). IES was significantly related to cardiorespiratory fitness in incongruent (r=-.373, p=.028) and control (r=-.333, p=.045) trials. Results suggest that increased cardiorespiratory fitness can improve reaction time and also induce greater efficiency.
Predicting Patients' Satisfaction With Doctors in Online Medical Communities
Authors: Xu Yunhong , Wu Guangyu , Chen Yu
Published: September 2021

Online medical communities have revolutionized the way patients obtain medical-related information and services. Investigating what factors might influence patients’ satisfaction with doctors and predicting their satisfaction can help patients narrow down their choices and increase their loyalty towards online medical communities. Considering the imbalanced feature of dataset collected from Good Doctor, we integrated XGBoost and SMOTE algorithm to examine what factors and these factors can be used to predict patient satisfaction. SMOTE algorithm addresses the imbalanced issue by oversampling imbalanced classification datasets. And XGBoost algorithm is an ensemble of decision trees algorithm where new trees fix errors of existing trees. The experimental results demonstrate that SMOTE and XGBoost algorithm can achieve better performance. We further analyzed the role of features played in satisfaction prediction from two levels: individual feature level and feature combination level.

Published: September 2021

Adoption and user perceptions are dominant on personal health records literature and have led to a better understanding of what individuals' behaviors and perceptions are about the adoption of personal health records. However, these insights are descriptive and are not actionable to allow creating personal health records that will overcome the adoption problems identified by users. This study uses action design research to provide actionable knowledge regarding user perceptions and adoption and their application in the case of the digital allergy card. To achieve this, we conducted interviews with patients and physicians as part of the evaluation of the digital allergy card mock-up and the first prototype. As results, we provided some research proposals regarding the benefits of, levers for, and barriers to adoption of the digital allergy card that can be tested for several other personal health records.

Published: September 2021

Purpose: This study aims to measure the relationship between corporate governance and dividend policy of Sri Lankan listed companies with the highest market capitalization, using the Agency theory. Methodology: The sample is based on the listed companies with the highest market capitalization at the Colombo Stock Exchange for a four-year period. The independent variables of this research include the board size, board independence, board gender diversity, board meetings, independent directors in audit committee, audit committee meetings, independent directors in remuneration committee and remuneration committee meetings. The dependent variables are dividend per share and dividend payout ratio. Descriptive analysis and Panel regression analysis were conducted to analyze the data. Findings: Independent directors in audit committee and return on assets have a significant positive impact on the dividend policy. Remuneration committee meetings have a significant negative impact on the dividend policy. However, board size, board meetings, board independence, board gender diversity, audit committee meetings, independent directors in remuneration committee, firm size and leverage have no significant impact on the dividend policy. According to the findings, corporate governance has an influence on the dividend policy of the listed companies during the period. Originality: This study fills the research gap in the local context, and this can be recommended for further research, changes in the academic concepts, and modifications in the accepted theories.

Published: September 2021

A comprehensive rehabilitation program is required after Pelvic Fracture (PF). In a PF rehabilitation setting an effective treatment and a proper management of complications is supplied by an appropriate and reliable clinical assessment. In this literature-based update, we search on MEDLINE, EMBASE, and the Cochrane Database of Systematic reviews to find articles, scientific society guidelines and practioners experiences defining the rehabilitative management of clinically PF outcomes. Based on literature evidences and expert opinions, a set of key topics was collated to generate advices and recommendations to put into daily practice. Even if there are no high-quality evidence for rehabilitative interventions after PF in terms of duration and modality of therapy, rehabilitation setting, care pathways, and long-term functional outcomes, it is strongly recommended an early multidisciplinary intervention to improve recovery from PF.

An exfoliative cytology study to assess oral mucosa of oral submucous fibrosis patients in Chennai, Tamil Nadu
Authors: Dhanvantri N. Vaishnavi , Karthik Raghavendhar , Rajkumar K.
Published: September 2021

Background:

Oral submucous fibrosis (OSMF) is a chronic, insidious disease that affects the oral mucosa. It is a progressive high risk potentially malignant disorder that leads to oral mucosa scarring.

Aim:

In this study, we aimed to study and compare the differences in the buccal cytological smear and the nuclear and cytoplasmic changes seen in the exfoliated cells of patients with OSMF and healthy controls, during preliminary screening.

Materials and Methods:

Patients with clinical OSMF (reduced mouth opening, blanched buccal mucosa, burning sensation in the buccal mucosa, palpable vertical bands) were included in the study. The cytological smears were stained with Papanicolaou stain and studied under light microscopy. The nuclear and cytoplasmic changes were recorded. The cytologic features that were assessed included the presence of keratinized squames, intermediate cells, inflammatory cells, cytoplasmic creasing, peri nuclear halo, and abnormal chromatin. In addition, the presence and absence of candidal organisms in the smear were assessed.

Results:

The cytological features which were seen to predominate in the OSMF patients were cells of intermediate and keratinized buccal epithelial cells, cytoplasmic creasing, and presence of inflammatory cells.

Conclusion:

We conclude that the results of our study indicate that there are cytological changes associated with OSMF that can be assessed with exfoliative cytology. The cellular pattern alterations recorded in our study adds on to the current knowledge pool and literature on OSMF. Further studies are necessary to validate the significance of such cellular alterations.
Gorlin–Goltz syndrome

Published: September 2021

Gorlin–Goltz syndrome (GGS), due to its sparse occurrence in various populations along with the variety of associated signs and symptoms, very often becomes a missed diagnosis. The most commonly associated triad with GGS is that of multiple odontogenic keratocysts in the jaws, skeletal abnormalities, and multiple basal cell nevus carcinomas. In many cases, each of these conditions is treated separately and the recognition of underlying syndrome is rare or happenstance. The case reported here is rare of its kind as it has been diagnosed in the first decade of life, thus avoiding the possibility of morbidity in later life in the form of neoplasia and hostile basal cell carcinomas. As per our knowledge, no case had yet been reported at this early age and it emphasizes the importance of pedodontist in early recognition of the syndrome.

Authors: Adeagbo M.A. , Akinsola J.E.T. , Awoseyi A.A. , Kasali F.
Published: September 2021

Selection of a suitable Software Development Life Cycle (SDLC) model for project implementation is somewhat confusing as there are a lot of SDLC models with similar strengths and weaknesses. Also, the solutions proffered among the researchers so far have been the  qualitative comparative analysis of SDLC models. Hence, this paper proposes a comparative analysis of SDLC models using quantitative approach in relation to strengths and weaknesses of SDLC models. The study adapted comparative analysis and Software Development Life Cycle (SDLC) models features’ classification using ten characteristics such as project complexity, project size, project duration, project with risk, implementation/initial cost, error discovery, associated cost, risk analysis, maintenance and cost estimation. A quantitative measure that employs online survey using experts in software design and engineering, project management and system analysis was carried out for the evaluation of SDLC models. Purposeful Stratified Random Sampling (SRS) technique was used to gather the data for analysis using XLSTAT after pre-processing, taking into consideration both benefit and cost criteria. The overall performance evaluation showed that Spiral-Model is the best followed by V-Model and lastly Waterfall Model with comparative values of 38.63%, 35.76% and 25.61% respectively. As regards cost estimation, Waterfall Model is the most efficient with value of 41%, then V-Model with 31% and lastly Spiral Model with 28%. V-Model has great error recovery capability with value of 45% which is closely followed by Spiral Model with 37% and lastly Waterfall Model with 18%. The study revealed that, a model with efficient risk assurance does not guarantee efficient cost management. In the future work, more characteristics regarding SDLC models shall be considered.

Authors: Osang Francis B. , Umoren Ime J. , Owolabi Abimbola O.
Published: September 2021

Modeling procurement management system is important for quality decision making regarding business capacity planning, supply and scheduling. In the Procurement Services Department (PSD), most commonly used indicators to measuring performance include supply period, products rating, ranking recommendations, resource scheduling and number of goods supplied and delivered. In this paper, a Decision Support Service (DSS) technique was proposed to optimize procurement services in business and public organization. First, a study of a typical public and private organization was conducted to gain insights into the operations of the procurement department and the contributions of important system parameters to procurement management. Second, a product and supplier collaborative filtering technique were investigated to obtain transformed data for model training and testing for implementation using Partial Correlation Coefficient (PCC). The Partial Correlation Coefficient (PCC) for a particular product or supplier was utilized for generating the outcomes with tuned values which were compared with actual observed outcomes. The residuals were evaluated in terms of linearity, normality, independence and constant variance. The visualized system plots indicate a good performance as the quality and accuracy of the decision support model was evaluated using some basic metrics. The overall system implementation and performance results demonstrated the importance of Decision Support Services in assessing the performance of procurement management systems. A robust tool for this assessment and a model for procurement and supply planning indicates that the system framework offered Quality of Service (QoS) provisioning.

Published: September 2021

The process of establishing the most likely author of a collection of texts or documents whose authorship must be verified is known as authorship attribution. Several studies have been reported in the literature on the task, but rarely any reported work on Yorùbá language texts. In this paper, the development of an automatic Yorùbá written texts authorship attribution system (YorAA) is reported. The literary works of six Yorùbá authors were considered. Stylometry features were extracted from the texts using the BoW approach and lexical/syntactic word frequencies approach. The Support Vector Machine, Multilayer Perceptron and Random Forest algorithms were used for the classification analysis. The experimental results showed that the developed YorAA system achieved accuracy, recall, precision and F1 measures values of 95%, 83%, 84% and 84% respectively on the average, for all the six authors. The results demonstrate that with a database of written texts in Yorùbá language, that is enough to extract relevant stylometry ´ features of the author and appropriate methods and tools applied to such features; the authorship of the texts can be identified or verified.

MicroRNA (miR, miRNA) là một phân tử RNA nhỏ có chiều dài từ 20 đến 25 nucleotide quy định sự biểu hiện của gene bằng cách liên kết đặc hiệu với trình tự 3’UTR trên mRNA đích. Trước đây, chúng tôi nhận thấy miR-146b-5p tuần hoàn tăng đáng kể trong huyết thanh của bệnh nhân Thoái Hoá Khớp (THK) và có thể có tiềm năng rất lớn để chẩn đoán bệnh sớm. Tuy nhiên, chức năng của miRNA này trong THK vẫn chưa được biết và cần được xác định. Vì vậy, nghiên cứu này được thực hiện nhằm xác định chức năng miR-146b-5p trong tế bào chondrocyte. Công cụ tin sinh học được thực hiện để dự đoán các con đường tín hiệu tiềm năng có tương tác với miRNA-146b-5p trong tế bào chondrocyte. Trong đó dữ liệu giải trình tự thế hệ mới cho mRNA có thể được biểu hiện trong tế bào khớp có sẵn trước đó được sử dụng. Dữ liệu cho thấy miR-146b-5p có thể tương tác với một số con đường tín hiệu quan trọng bao gồm Wnt, Notch, Toll like receptor, P38 MAPK, Anti apoptosis, Adhesion, Cadherin, Intergin. Do đó, sự biểu hiện bất thường của microRNA 146-5p có thể dẫn đến đến thoái hoá khớp ít nhất có thể là do rối loạn các đường truyền tín hiệu này.

Authors: Ben Amar Fathi , Guellaoui Imen , Ayadi Mohamed , Elloumi Olfa , Triki Mohamed Ali , Boubaker Mohsen
Published: September 2021

An olive breeding program was started in Tunisia in 1993 in order mainly to improve the fatty acid composition of the local cultivar ‘Chemlali Sfax’. ‘Zeitoun Ennour’ is a new cultivar obtained from a cross between ‘Chemlali Sfax’ and the local dual-purpose use cultivar ‘Chemchali Gafsa’. The morphological study of this cultivar showed that eleven characters dealing with fruit and endocarp differed from ‘Chemlali Sfax’, mainly regarding to their respective weights. This new cultivar had the same sensitivity to Verticillium dahliae Kleb and earlier bearing than the original variety. Its olive production was considered as high as for ‘Chemlali Sfax’ but with partial self-compatibility and late maturity. The new cultivar realized a net improvement in comparison with the original cultivar particularly regarding its fatty acid composition with very high oleic acid content (>75 %) and low palmitic and linoleic acid contents (<10 %). The new cultivar was recently released and will be available for growers as soon as possible.
Cartesian Difference Categories
Authors: Alvarez-Picallo Mario , Lemay Jean-Simon Pacaud
Published: September 2021

Cartesian differential categories are categories equipped with a differential
combinator which axiomatizes the directional derivative. Important models of
Cartesian differential categories include classical differential calculus of
smooth functions and categorical models of the differential $\lambda$-calculus.
However, Cartesian differential categories cannot account for other interesting
notions of differentiation of a more discrete nature such as the calculus of
finite differences. On the other hand, change action models have been shown to
capture these examples as well as more "exotic" examples of differentiation.
But change action models are very general and do not share the nice properties
of Cartesian differential categories. In this paper, we introduce Cartesian
difference categories as a bridge between Cartesian differential categories and
change action models. We show that every Cartesian differential category is a
Cartesian difference category, and how certain well-behaved change action
models are Cartesian difference categories. In particular, Cartesian difference
categories model both the differential calculus of smooth functions and the
calculus of finite differences. Furthermore, every Cartesian difference
category comes equipped with a tangent bundle monad whose Kleisli category is
again a Cartesian difference category.
Hamiltonian structures for integrable hierarchies of Lagrangian PDEs
Authors: Vermeeren Mats
Published: September 2021

Many integrable hierarchies of differential equations allow a variational
description, called a Lagrangian multiform or a pluri-Lagrangian structure. The
fundamental object in this theory is not a Lagrange function but a differential
$d$-form that is integrated over arbitrary $d$-dimensional submanifolds. All
such action integrals must be stationary for a field to be a solution to the
pluri-Lagrangian problem. In this paper we present a procedure to obtain
Hamiltonian structures from the pluri-Lagrangian formulation of an integrable
hierarchy of PDEs. As a prelude, we review a similar procedure for integrable
ODEs. We show that exterior derivative of the Lagrangian $d$-form is closely
related to the Poisson brackets between the corresponding Hamilton functions.
In the ODE (Lagrangian 1-form) case we discuss as examples the Toda hierarchy
and the Kepler problem. As examples for the PDE (Lagrangian 2-form) case we
present the potential and Schwarzian Korteweg-de Vries hierarchies, as well as
the Boussinesq hierarchy.

Intracorporeal laparoscopic suture (ICS) is an important skill of the surgeon in performing laparoscopic procedures. Simulation training in this skill contributes to the formation of a skill and its implementation in operational practice. There are not enough publications highlighting the effectiveness of simulation training of the skill from the point of view of application in practice. Interviews were conducted with surgeons who underwent such simulation training in order to determine the proportion of doctors who applied the acquired skill in a real operating room. After training 88.9% of surgeons started using Intracorporeal laparoscopic suture; intracorporeal sliding knot — 77.3%.
