LEARNING STYLE AND ACADEMIC ACHIEVEMENT IN ENGINEERING STUDENTS Abstract The purpose of this study is to analyze the learning styles of students in engineering careers and their relationship with academic performance, and the comparison between men and female regarding learning styles. The Honey Alonso Learning Styles Questionnaire (CHAEA) was administered to a sample of 170 students from four engineering programs. It was found that the predominant learning style was reflective (mean = 14.44). We also found a significant positive relationship between pragmatic learning style and academic performance, in both Computer Systems Engineering and Industrial Engineering; we found a significant positive relationship between theoretical learning style and academic performance among students of the Electromechanical Engineering program. Finally, we only found significant differences by sex in their mean academic performance. Women had higher academic performance than men.
An edge priority‐based clustering algorithm for multiprocessor environments

In multiprocessor environments, the scheduling algorithms play a significant role in maximizing system performance. In this paper, we propose a clustering‐based task scheduling algorithm called Edge Priority Scheduling (EPS) for multiprocessor environments. The proposed algorithm extends the idea of edge zeroing heuristic and uses the concept of edge priority to minimize the makespan of the task graph. The complexity of the EPS algorithm is O(|V||E|(|V| + |E|)), where |E| represents the number of edges and |V| denotes the number of nodes in the task graph. The experiments are performed for random task graphs and the task graphs generated from some representative real‐world applications such as Gaussian Elimination and Fast Fourier Transform. The performance of the EPS algorithm is compared with six well‐known algorithms such as EZ (Edge Zeroing), LC (Linear Clustering), CPPS (Cluster Pair Priority Scheduling), DCCL (Dynamic Computation Communication Load), RDCC (Randomized Dynamic Computation Communication), and LOCAL. The results show that the EPS algorithm outperforms the compared algorithms in terms of the normalized schedule length and speedup.
Effective Measurement of the Functional Progress of Stroke Clients

There is a need for occupational therapists to establish a range of outcome measures that can measure change effectively. The aim of this study was to identify effective methods of measuring the functional performance of individuals who had experienced a stroke and had been discharged from a rehabilitation ward. Measures with recorded validity and reliability and in clinical use were selected. The measures were the Barthel Index (Shah version), Nottingham Extended Activities of Daily Living scale, Motricity Index (Upper and Lower Limb), Rivermead Mobility Index and Nine-Hole Peg Test. Assessments were carried out at the point of discharge from hospital and 6 months later. Responsiveness was analysed using effect size and relative efficiency statistics. The practicality (feasibility) was established by comparing completion rates. The Nottingham Extended Activities of Daily Living scale and the Rivermead Mobility Index were found to be more responsive than the Barthel Index and Lower Limb Motricity Index respectively and to be practical after discharge from hospital. The Nine-Hole Peg Test was found to be more responsive than the Upper Limb Motricity Index but less practical. The analysis suggested that some measures are more suitable than others for tracking change in function after discharge from hospital for a wide case mix of people who have experienced a stroke.
Exploring electronic forum participation and interaction by efl speakers in two web-based graduate-level courses

The purpose of this study is to describe forum participation of international graduate students who speak English as a foreign language in two Web-based graduate courses. Research questions focused around how linguistic and cultural differences impact nonnative speaking international students' perception of classroom participation, what effect computer-mediated communication has on their forum participation and interaction in Web-based courses and how their discussion participation is different from domestic students. Data was collected through basic information survey, electronic transcripts of student and instructor entries in the course forum, face-to-face and email interviews, and the researcher's observations and field notes. Both quantitative and qualitative techniques were used in data analysis. Participants' actual classroom participation and their perceptions were compared and contrasted for a better understanding. Results show that although Web-based forum discussion creates unique difficulties for international students' discussion participation, its unique characteristics provided them with a more equal opportunity to vocalize.

Fitting the damped trend method of exponential smoothing

Abstract The well-established forecasting methods of exponential smoothing rely on the “optimal” estimation of parameters if they are to perform well. A grid search procedure to minimise the MSE is often used in practice to fit exponential smoothing methods, especially in large inventory control applications. Grid searches are also found in some modern statistical software. We ask whether the ex ante forecast accuracy of the damped trend method of exponential smoothing can be improved by optimising parameters. Furthermore, we ask whether the method should be fitted according to a mean absolute error criterion rather than the mean squared error commonly used in practice. We found that model-fitting matters. Parameter optimization makes significant improvements in forecast accuracy regardless of the fit criterion. We also show that the mean absolute error criterion usually produces better results.
Optimization of the PEMFC operating parameters for cathode in the presence of PtCo/CVD graphene using factorial design

Chemical vapor deposition (CVD) grown graphene‐supported PtCo catalyst was developed as a polymer electrolyte membrane fuel cell (PEMFC) cathode. The effects of cell temperature, back pressure, relative humidity, anode, and cathode flow rates on the fuel cell performance were investigated utilizing Design Expert software for statistical analysis. Cell temperature, back pressure, and relative humidity were shown to be the most critical factors to improve fuel cell performance in the presence of PtCo on CVD grown graphene. The maximum current density of 1779.5 mAcm−2 and power density of 785.38 mWcm−2 are obtained at cell temperature of 79.99°C, back pressure of 4.99 psi, relative humidity of 50%, anode flow rate of 0.156 dm3min−1, and cathode flow rate of 0.199 dm3min−1.
URINARY CONNECTIVE TISSUE GROWTH FACTOR LEVEL AS AN EARLY NON-INVASIVE BIOMARKER OF CHRONIC ALLOGRAFT NEPHROPATHY

Background: Chronic allograft nephropathy (CAN) is a major cause of renal graft loss. Connective tissue growth factor (CTGF) expression is increased in fibrotic renal diseases including diabetic nephropathy and CAN. Objective: Assessing urinary CTGF as a non-invasive marker of CAN. Patients and method: Urinary CTGF was measured in samples collected from all the study candidates which included transplanted patients with normal kidney functions tests and estimated glomerular filtration rate(e GFR) more than 60 ml/minute as a control, transplanted patients with biopsy-proven diagnosis of IF/TA indicating presence of CAN, and e GFR between 30 -59 ml/minute and transplanted patients with biopsy-proven diagnosis of interstitial fibrosis (IF/TA), indicating presence of CAN, and e GFR less than 30 ml/minute. To assess the effect of the native kidneys, hemodialysis patients were recruited and their urine samples were collected and to measure CTGF. To adjust for decreasing GFR and urine output, urinary creatinine was measured in all samples, and CTGF/creatinine ratio was calculated. Results: The mean urinary CTGFin patients with CAN was significantly higher than the mean level in transplant candidates with normal kidney function.The mean urinary CTGF in patients with CAN and marked graft dysfunction was significantly higher than the mean level in those with milder graft dysfunction. The mean urinary CTGF was found to be significantly higher in patients with history of acute rejection than in those without history of acute rejection. There was a significant positive correlation between urinary CTGF level and both of serum creatinine and duration of transplantation, and a negative correlation between urinary CTGF level and e GFR. The CTGF/creatinine ratio showed similar results. Conclusion: Urinary CTGF level and CTGF/creatinine ratio could be used as an early non-invasive marker of chronic allograft nephropathy.
Biocidal activity of Sygium aromaticum (Willd) against on the larval mosquito of Culex quinquefasciatus (Say.) (Diptera: Culicidae)

To determine the larvicidal, ovicidal and repellent activities crude Ethylene glycol and acetone extract of Syzium aromaticum against Culex quinquefasciatus. Thirty third, fourth and fifth instarlarvae was selected and it was exposed to various concentrations (100, 150 and-200 ppm) in the laboratory condition. The repellent efficacy was determined against selected mosquitoes at three concentrations viz., 100, 150 and 200ppm under the laboratory conditions. Furthermore, maximum 150 and 200ppmconcentration of acetone extract remarkably showed hundred percentage of repellent effect has been noticed on third fourth and fifth instar larvae of the mosquito except 100ppmin third instar larva. Similarly another extract of ethylene glycol experimental extract was also shown the following repellent effect such as 97.06, 92.57 and 91.34 percentage been noticed on 3 rd, 4th and 5th instar larvae respectively. The LC50 and LC90 values of acetone extract of S. aromaticum against the C. quinquefasciatus larvae in 24 h were as follows7.31, 8.4 and 9.27 represent the third, fourth and fifth instar larvae. Similarly ethylene glycol extract also denoted 9.67. 11.12 And 12.94ppm, respectively. In addition bioactive compounds were analysed through a GCMS technique. Totally eight compounds were identified in the S. aromaticum acetone extracts, representing the 99% of the crude extract, while two compounds such as α,α’humulene and 3,4-di- acetate Eugenol were identified as a peak compoundalong with its retention time and peak abundance 11.64mts 52.53; 17.54mts 62.45% respectively. Meanwhile, 1, 2-dihydroxy eugenol compound observed as a least compound along with fifth and eigth compounds are trace and unknown compounds. Moreover, 2, 2’ dihydroxy copene and 1,2-dihydroxy eugenol two compounds are appeared as an optimum level in the experimental extract. From the results it can be concluded the S. aromaticum acetone extract was an excellent potential for controlling three life stages of C. quinquefasciatus mosquitoes larvae because the mosquitocidal bioactive compound was present in the same experimental plant. Hence the present study was clearly showed that the S. aromaticum acetone extract act as a probable mosquitocidal agent.
The effect of topical knowledge on ESP learners’ writing quality: complexity, accuracy, and fluency measures

Practitioners of English for specific purposes (ESP) appraise the impact of different factors in writing quality of ESP learners. One of the least researched factors which seems to play an undeniable role in writing quality of ESP learners is topical knowledge. Given that, the purpose of this study is to investigate the effect of topical knowledge on writing quality of ESP learners in terms of complexity, accuracy, and fluency measures. To this end, 34 civil engineering students whose language proficiency was at upper-intermediate level and studied at the seventh semester of BA participated in this study. The participants were asked to write about a topic requiring general knowledge and the one demanding topical knowledge. A series of ANOVAs were run to analyze the writing quality of ESP learners, examining complexity, accuracy, and fluency measures. The results revealed that ESP learners produced more accurate and fluent writing productions when they wrote about the topic requiring topical knowledge. However, there was no statistically significant difference in the writing quality of ESP learners in terms of complexity measures when they wrote about general and topical prompts. The findings carry some implications for assessing and teaching writing skill in ESP context.
Analyzing Deep Learning Based Brain Tumor Segmentation with Missing MRI Modalities

This technical report presents a comparative analysis of existing deep learning (DL) based approaches for brain tumor segmentation with missing MRI modalities. Approaches evaluated include the Adversarial Co-training Network (ACN) [6] and a combination of mmGAN [5] and DeepMedic [2]. A more stable and easy-to-use version of mmGAN is also open-sourced at a GitHub repository 3 . Using the BraTS2018 dataset, this work demonstrates that the state-of-the-art ACN performs better especially when T1c is missing. While a simple combination of mmGAN and DeepMedic also shows strong potentials when only one MRI modality is missing. Additionally, this work initiated discussions with future research directions for brain tumor segmentation with missing MRI modalities.

Characteristics of abused women and factors that enhanced abuse

The aim of this study was to assess the characteristics of abused women who visited Masonwabisane Women Support Centre (MWSC) in Butterworth, Eastern Cape, South Africa. Data was collected at MWSC, an NGO operating under Mnquma local municipality. A descriptive quantitative approach was used where records of abused women (245) were reviewed retrospectively with effect from the 1st of July to 31st December 2007. The records were divided according to the areas served by the organization and the sub-sample randomly selected from each area. The analysis was based on the information that was generated from the records at the centre. The study showed that the majority of the women (94%) were below the age of 40 years of which 49% were single and almost all were living in the rural or informal settlement. Only ten (4%) of the participants had no formal education while close to 82% had at least a secondary school education and the rest 14.3% had tertiary education. About 24% of the participants were unemployed and 26.9% were students. The rest of the respondents were either in full-time (15.1%) or in part-time (33.9%) employment. At the time of presentation at the centre, two third (75%) of the participants were traumatized or injured 24%, 13% confused while 8.6% were reserved and 2.9% not well groomed. Over half (55.5%) of the cases were emotional abused, followed by physical abuse at 31% while sexual abuse were 7.3. % and economical abuse were 6.1%. Over a quarter (33.5%) of them used tobacco, 10.2% used alcohol and 3.3% used illicit drug while over half (53.1%) of them did not use any form of substance. Almost half (44%) of the abused women were angry, 26% were stubborn and 15% were submissive while 14% were aggressive. One tenth (12%) of women were abused during their pregnancy and 25% during their menstrual period. Because of the abuse, 24% were physically disabled. Two thirds (66%) of the women with children between 1 and 4 were abused. Majority (80%) of women were abused by their husband or partners. Results showed that employment and obstetric status were significantly associated (Χ2 = 96.24, P<0.001). Type of abuse was not dependent on any other variables in the study. Frequency of reporting was associated with type of substance used (Χ2 = 18.94, P = 0.04) and relationship with perpetrator (Χ2 = 94.78, P<0.001). Occupation of the perpetrator was related to obstetric status (Χ2= 193.58, P<0.001), disability (Χ2 = 34.51, P<0.001) and number of children the women had (Χ2 = 116.23, P<0.001). The most common form of abuse reported among participants were emotional abuse (emotional abuse showed highest incidence) and physical abuse. Key words: Domestic violence, Characteristics of abused women, patterns of reporting.
Occupational Therapy as Documented in Patients' Records: Part I. A Content Analysis of Occupational Therapy Records at an Occupational Therapy Department

Current laws and regulations concerning the recording and quality assurance of care and rehabilitation within the Swedish health care system form a frame of reference in the documentation and evaluation of professional interventions. Cooperation between the College of Health Sciences and an occupational therapy department at a geriatric hospital has resulted in a review of existing documentation of occupational therapy, as demonstrated in 11 records regarded by the occupational therapists as satisfactory. The occupational therapy process, Act of Patient Record and Code of Ethics were used as a framework in the analysis. The findings show that problem identification consists of assessment of previous occupational performances, present functional limitations and present occupational performance problems. Goal setting and treatment planning were only briefly reported, and interventions were expressed as traditional legitimated tools of occupational therapy. Evaluation was documented as a process, including t.
Calcium Isotope Ratio (δ44/40Ca) Measurements of Ca‐Dominated Minerals and Rocks without Column Chemistry Using the Double‐Spike Technique and Thermal Ionisation Mass Spectrometry

In this study, to evaluate whether bias free Ca isotope ratios can be properly achieved by thermal ionisation mass spectrometry (TIMS) using the 42Ca–43Ca double‐spike technique without chemical purification, a series of comparable experiments (with or without column chemistry) were made on Ca‐dominated minerals and rocks. Minerals, including fluorite, calcite, titanite and apatite, displayed similar Ca isotope ratios with Δ44/40Cawith‐without ranging from −0.02 to +0.07‰. For Ca‐rich rocks, we mainly focused on the carbonates since they are the main repositories of Ca at the surface of the Earth. Coral, stalagmite, carbonatite, dolomite, marble and limestone are studied here. Interestingly, δ44/40CaSRM 915a of these minerals and rocks without chemical purification displayed little drift compared with that of rocks with chemical purification, with Δ44/40Cawith‐without merely spanning from −0.04 to +0.04‰. This implies that Ca isotope ratios can be achieved without column chemistry, possibly due to a property of TIMS in which Ca ions are only ionised at a target temperature and with a specific activator without ionising other ions. Therefore, for Ca‐dominated minerals or rocks, we suggest that column chemistry is unnecessary if they are totally dissolved and mixed in proper proportion with the 42Ca–43Ca double spike for TIMS measurement.

Polycystic Ovary Syndrome

Women with polycystic ovarian syndrome have chronic anovulation and androgen excess not attributable to another cause. This condition occurs in approximately 4% of women. The fundamental pathophysiologic defect is unknown, but important characteristics include insulin resistance, hyperandrogenism, and altered gonadotropin dynamics. Inadequate follicle-stimulating hormone is hypothesized to be a proximate cause of anovulation. Obesity frequently complicates polycystic ovarian syndrome but is not a defining characteristic. The diagnostic approach should be based largely on history and physical examination, thus avoiding numerous laboratory tests that don’t contribute to clinical management. Women with polycystic ovarian syndrome typically present because of irregular bleeding, hirsutism, and/or infertility. These conditions can be treated directly with oral contraceptives, oral contraceptives plus spironolactone, and ovulation induction, respectively. However, women with polycystic ovarian syndrome also have a substantially higher prevalence of diabetes and increased risk factors for cardiovascular disease. They should also be screened, therefore, for these conditions and followed closely if any risk factors are uncovered. For obese women with polycystic ovarian syndrome, behavioral weight management is a central component of the overall treatment strategy.
