Illuminating Impediments in Pre-Service Teachers preparation for Inclusive Pedagogies: A phenomenological approach at Mufulira College of Education, Zambia

-This study was grounded in the constructivist paradigm and guided by Vygotsky theory to understand and analyse description of phenomena relating to preservice preparedness in inclusive pedagogies. The purpose of this transcendental phenomenological study was to construct a shared essence of lived experiences of how pre-service teachers are prepared in inclusive pedagogies. Purposive sampling was employed to select Six participants; two females and four males in their third and final year of secondary teachers diploma studies. Data were generated through phenomenological observation, semi structured and focus group interviews. It was later analysed through phenomenological reduction in which transcription of verbatim were clustered into themes by horizontalisation, creating meaningful units and developing textural descriptions. The findings from participants’ essences reveal that; Developing inclusive pedagogies among pre-service teachers demands a recognition and welcoming disposition towards diversity. The challenges in their practices were drawn from demand for planning time, practice & commitment, Overcrowded classrooms, poor modelling of the practice from lecturers to identifying learner diversities in a classroom. Theory lessons in teacher education systems should pursue core features of growth mindset, values and norms that embrace social justice. These lessons should also be linked to practicum components of the peer, school visitation observations and field based platforms of preparing pre-service teachers as a way of modelling what we
Exploratory Large Scale Graph Analytics in Arkouda

Exploratory graph analytics helpsmaximize the informational value for a graph. However, the increasing graph size makes it impossible for existing popular exploratory data analysis tools to handle dozens-of-terabytes or even larger data sets in the memory of a common laptop/personal computer. Arkouda is a framework under early-development that brings together the productivity of Python at the user side with the high-performance of Chapel at the server side. In this paper, the preliminary work on overcoming the memory limit and high performance computing coding roadblock for high level Python users to perform large graph analysis is presented. A simple and succinct graph data structure design and implementation at both the Python front-end and the Chapel back-end in the Arkouda framework are provided. A typical graph algorithm, Breadth-First Search (BFS), is used to show how we can use Chapel to develop high performance parallel graph algorithm productively. Two Chapel based parallel Breadth-First Search (BFS) algorithms, one high level version and one corresponding low level version, have been implemented in Arkouda to support analyzing large graphs. Multiple graph benchmarks are used to evaluate the performance of the provided graph algorithms. Experimental results show that we can optimize the performance by tuning the selection of different Chapel high level data structures and parallel constructs. Our code is open source and available from GitHub (https://github.com/Bader-Research/arkouda).
Online Anomaly Detection in Time-Series

Methods for online anomaly detection are designed to reveal anomalies in a continuous stream of data rather than in a static dataset. These methods are able to adapt to the changes of underlying characteristics of the stream that might occur in time (concept drift). This thesis reviews four methods suitable for online anomaly detection in time-series (moving average, local outlier factor, isolation forest, hierarchical temporal memory) and several concept drift detection methods including some novel approaches. A general framework that allows to orthogonally combine various anomaly detection methods and concept drift detection methods is proposed. Experiments were executed for all reviewed methods on five real-world datasets and one artificial dataset. During the experiments, the properties of individual methods were examined as well as their performance compared to the other methods. Results of the experiments show that none of the methods is superior to the others on all datasets in terms of F1 score adapted for anomaly detection (harmonic mean of recall and false positive rate) and AUC. In the majority of cases, an optimal method settings with F1 score > 85% and AUC > 90% was found.
FUZZY LOGIC CONTROLLER FOR THREE-LEVEL SERIES ACTIVE POWER FILTER TO COMPENSATE VOLTAGE HARMONICS

In this paper, the three-level inverter is used as a series active power filter to suppress harmonic voltage drawn from a nonlinear load. This filter acts as zero impedance for the fundamental frequency and as high resistor for harmonic frequencies. Most previously reported three-phase series active power filters are based on two-level inverters with conventional controllers requiring a complex and a complicated mathematical model. To overcome this problem a fuzzy logic controller is used and extended to a three level series active power filter. This work presents principles of operation and design of a fuzzy logic controller algorithm to control the harmonic voltages. The viability of the proposed algorithm is validated with computer simulation. The obtained results showed that source voltage is sinusoidal and in phase with source current as well as a reduced total harmonic distortion.
Canvas Deceiver - A New Defense Mechanism Against Canvas Fingerprinting

Browser fingerprinting refers to a collection of techniques used to gather information about a user’s browser attributes. The information gained from a browser fingerprint can be used to partially or fully identify a user without using any other technique, e.g., cookies. One type of browser fingerprinting is canvas fingerprinting which utilizes HTML-canvas elements to identify users. Various defense algorithms against canvas fingerprinting have been developed, but unfortunately, have been shown to be penetrable and detectable. In this paper, we present Canvas Deceiver, a new countermeasure against canvas fingerprint. Canvas Deceiver is a browser extension that uses a new algorithm that is different from existing problem-possessing algorithms. Canvas Deceiver does not rely on randomness, does not provide a unique identity, and is not detectable. To show its functionality and effectiveness, we tested Canvas Deceiver using different tools that provide browser fingerprint tests. According to the test results, Canvas Deceiver outperforms current countermeasures in detectability while providing sufficient anonymity to its users. For instance, in Browserleaks, the user originally was put into a group with 634 people. After using Canvas Deceiver, he is put into a group with 7847 people.
TEleRehabilitation Nepal (TERN) to improve quality of life of people with spinal cord injury and acquired brain injury. A proof-of-concept study.

Background: Spinal Cord Injury (SCI) and Acquired Brain Injury (ABI) lead to unemployment, poverty, increased mortality and decreased quality of life in low-and middle-income countries (LMICs). Telemedicine is increasingly facilitating access to healthcare, in LMICs. This prospective cohort intervention study aims to investigate feasibility and acceptability of telerehabilitation to provide long-term follow-up of individuals with SCI and ABI, in Nepal, post-discharge from hospital. Methods: TERN was delivered by Spinal Injury Rehabilitation Centre, Nepal, in collaboration with University of Leeds, UK. A home visit connected participants to the Multidisciplinary Team (MDT), through a specialised video conference system. The MDT performed a comprehensive assessment before recommending personalised interventions. Outcome measures assessed functional independence in performing activities of daily living, health-related quality of life and emotional disturbances using Modified Barthel Index, EuroQoL-5D, and Depression, Anxiety, Stress Scale, respectively. A subset of participants was interviewed, exploring acceptability of telerehabilitation. Findings: Between January and December 2020, 97 participants with SCI (n = 82) and ABI (n = 15) were enrolled. After receiving telerehabilitation, significant improvement to self-reported functional independence (p<.001) and quality of life were found, (p<.001). Self-reported severity of depression, anxiety and stress significantly decreased (p<.001). Qualitative interviews (n = 18) revealed participants accepted telerehabilitation, they valued regular contact with professionals without costly, difficult travel. Interpretation: This is the first study to test telerehabilitation in Nepal. This approach can be safely delivered for long-term follow-up for individuals with SCI or ABI, overcoming geographical barriers to healthcare access. A larger-scale controlled study is required to further explore clinical and cost-effectiveness.
Implicit Government Guarantees and Equity Returns

This paper investigates the effect of implicit government guarantees on equity returns by sorting financial institutions according to the systemic risk measures ∆CoVaR and the marginal expected shortfall, MES. In alignment with the risk-return trade off, riskier firms should earn higher expected returns. However, risky financial institutions also pose a threat to financial stability and can be considered too-big-to-fail. From this perspective it can be argued that the risk adjusted expected returns should be lower for highly systemic financial institutions than for less systemic institutions due to the loss absorbing capacity of the systemic institutions’ tail risk by the government. By determining systemic importance from ∆CoVaR and MES, I find no evidence that points towards the perception that implicit government guarantees incurred lower risk-adjusted returns during the period 1987-2013.
Correlation Between Mini Nutritional Assessment and Anthropometric Measurements Among Community-Dwelling Elderly Individuals in Rural Southern Thailand

Purpose The Mini Nutritional Assessment (MNA) can be applied to assess nutrition status among community-dwelling elderly individuals by health care professionals. This study aimed to evaluate the correlation of MNA score and anthropometric measurements, gait speed, and handgrip strength among elderly community members. The secondary outcome was to compare the performance of the MNA-SF with the full MNA. Materials and Methods The study was a cross-sectional study with 176 elderly individuals aged ≥60 years living in rural southern Thailand. The MNA-SF and full MNA scores were obtained by using the standard form in the Thai version of the MNA. We collected anthropometric measurements, gait speed, handgrip strength, and MNA data. Results There was a significant positive correlation between body weight, BMI, waist circumference, hip circumference, waist-to-height ratio, waist-to-hip ratio, mid-upper arm circumference, calf circumference, triceps skinfold thickness, handgrip strength and full MNA total score using the partial correlation coefficient after controlling for age and sex. The MNA-SF had sensitivity of 78.79%, specificity of 81.82%, PPV of 50%, NPV of 94.35%, LR+ of 4.33, LR- of 0.26, accuracy of 81.25% and AUC 0.901 when using the full MNA as a reference standard. Conclusion The MNA correlated with many anthropometric measurements. The MNA-SF had a high specificity, NPV and accuracy of more than 80% when compared with the full MNA.

Totally 133 genes were annotated, including 87 protein-coding genes, 36 tRNA genes, and eight rRNA genes. We also detected two pseudo-genes (ycf1 and rps19). The overall GC content of the whole genome is 37.7%. The phylogenetic tree based on 23 complete plastomes indicated that S. wettsteiniana was closely related to S. involucrata of Compositae.
Visual Outcomes in Pediatric Patients with Peters Anomaly

Purpose This study aimed to evaluate the visual outcomes of pediatric patients diagnosed with Peters anomaly (PA) in a tertiary eye care center. Methods This was a retrospective study undertaken at a single academic center. Clinical records of pediatric patients diagnosed with PA from 2000 to 2017 were reviewed. Parameters recorded included visual acuity (VA), intraocular pressure (IOP), presence of glaucoma, and surgical procedures performed. The impact of PA type on final visual acuity levels was analyzed using generalized estimation equation models. Results Twenty-one eyes from 11 patients were analyzed. At the final visit, 9 eyes (42.8%) had a VA ≥20/200, while 12 (57%) had <20/200, ranging from 20/250 to no light perception. Of the study cohort, 15 (71.5%) eyes had type I, while six (28.5%) had type II PA. Glaucoma was present in 20 eyes (95%) at the final visit. One eye had dense central leucoma and microphthalmos where IOP could not be measured accurately. Seventeen eyes (81%) underwent at least one intraocular surgery, while the average number of surgeries per eye was 2.9 ± 2.5 (range=0– 9). The type of PA beta(se)=0.53 (0.41), p = 0.20] was not found to be a significant risk factor for worse VA. Conclusion Severe visual impairment develops in the majority of patients with PA. The type of anomaly does not appear to be associated with a worse visual function in patients with PA. Glaucoma develops in a high percentage of this patient population, and thus close monitoring of IOP in this patient population is crucial.

Personal Determinants for Physical Activity Behavior of Urban-Dwelling Older Adults in Sri Lanka

Physical inactivity is a vital risk factor for the development and maintenance of chronic ill-health conditions among older adults. This study examined personal factors associated with physical activity (PA) behavior of urban-dwelling older adults in Sri Lanka, a middle-income country in South Asia. A total of 880 older adults (aged ≥60 years) participated in this cross-sectional study. They responded to anthropometrical, health, and socio-demographic data pertaining to their current physical and behavioral status. The mean age of the participants was 70.1 years (SD ±6.0), and the majority (75%) were women. Increasing age, male gender, middle income, having cardiovascular diseases or arthritis, deficiencies in muscle strength and balance, pain, and lower self-rated health were associated with insufficient PA behavior among the participants. Old-age physical activity promotion programs should target older adults in advanced ages and men in particularly, as they are highly vulnerable to sedentary lifestyles. Muscle strength and balance, a neglected area in PA promotion in older adults, seem to play an important role in older adults’ participation in physical activities. Incorporation of pain management, and muscle strength and balance techniques into older adults’ PA promotion programs would probably increase adherence rates of the participants in such programs.

Effect of Rising Temperature Due to Ozone Depletion on the Dynamics of a Prey-Predator System: A Mathematical Model

It is well recognized that the greenhouse gas such as Chlorofluoro Carbon (CFC) is responsible directly or indirectly for the increase in the average global temperature of the Earth. The presence of CFC is responsible for the depletion of ozone concentration in the atmosphere due to which the heat accompanied with the sun rays are less absorbed causing increase in the atmospheric temperature of the Earth. The increase in the temperature level directly or indirectly affects the dynamics of interacting species systems. Therefore, in this paper a mathematical model is proposed and analyzed using stability theory to asses the effects of increasing temperature due to the greenhouse gas CFC on the survival or extinction of populations in a prey-predator system. A threshold value in terms of a stress parameter is obtained which determines the extinction or existence of populations in the underlying system.
