Model-driven aspect adaptation to support modular software evolution

One of the biggest challenges of software evolution is to adapt a software system to the ever-changing requirements from users or operating environments. An ideal goal is to encapsulate these requirements into a high-level abstraction, which can drive large-scale adaptation of the underlying software implementation. Model-Driven Engineering (MDE) is one of the enabling techniques that support this objective, in that it allows the application designers to synthesize various software artifacts from high-level models. The state-of-the-art MDE techniques, however, lack support for advanced processes and constructive methods for software evolution. With respect to large legacy systems written in disparate programming languages, the primary problems of evolution are the difficulty of adapting the legacy source to match the evolving requirements specified in the models and the incapability of developing evolutionary tasks in a modular way. In order to overcome such difficulties, this dissertation introduces a Model-Driven Aspect Adaptation (MDAA) framework that unites the MDE and Aspect-Oriented Software Development (AOSD) approaches to support modular software evolution. AOSD offers an advanced technique that supports invasive adaptation by weaving aspect modules that encapsulate the evolutionary crosscutting changes into the software system. By combining MDE and AOSD, the evolutionary change requirements are specified in the high-level aspect models, which drive the generation of the low-level aspect code used to perform legacy system evolution. This way, the whole software evolution process is performed in a modular manner, which enables the changeability, comprehensibility and independent development of the evolved implementation. Two case studies are provided to demonstrate the applicability and benefit of the approach. One is based on the paradigm of Domain-Specific Modeling (DSM), which leverages a DSM modeling environment, a model transformation engine and a program transformation system to provide evolution support for legacy systems from domain models. Another case study is based on UML activity modeling. An Aspect-Oriented Activity Modeling (AOAM) approach is implemented to facilitate modular evolution for activity models. In addition, the corresponding AspectJ code is generated from the aspect-activity models to enable evolutionary adaptation of the underlying legacy source.
Deconstruction, confusion and frequency: Surveying technology use by vocational teachers

This paper reports on a survey of the use of online technology by VET teachers and compares the survey method with similar research. While there is some comparison of results from similar surveys, this is not the central concern of the paper. It is argued that surveys into the adoption of technology for teaching and learning require the deconstruction of the functionalities of the technology in terms that are relevant to the respondent group. The use general and ill-defined terms such as online learning and elearning are ineffective in providing meaningful data on the uptake of technology for teaching and learning. My second contention is that surveys should provide an option for the respondent to indicate that they are either not sure or do not understand the question. Finally, I contend that effective surveying of technology for teaching and learning should collect data related to the frequency with which the respondent uses the specific functionality. In the absence of such data it is not possible to determine if the use is a novel experience that has not been repeated or the use of the functionality in a systematic manner.
Effect of pruning on yield and Fruit Quality of Guava Trees

This investigation was done during two successive seasons (2009/2010 and 2010/2011) on 10 years old seedy guava (Psidium guajva, L) trees planted at 5x5 meters surface irrigationat Mariout Research Station of the Desert Research Center- Alexandria. This investigation aimed to study the effect of some pruning treatments: 1- Control (unpruned trees). 2- Apical ten cm of new shoots were pruned. 3- Apical twenty cm of new shoots were pruned, in three dates:May, June and July on yield and fruit quality of guava trees. The obtained results showed that,number of fruits per tree, yield per tree and fruit weight was better with apical 10 cm of pruning shoots with May, while fruit set percentage and total sugars were better with apical 10 cm of pruning shoots at May and June. In the other side, fruit weight and fruit volume gave the highest values with apical 20 cm of new pruned shoots at May and June, while TSS gave the highest values with apical 10 and twenty cm of new pruned shoots at May and June, but fruit dry weight percentage gave insignificant differences among treatments in first season, but gave highest results in second season with apical 10 cm of new pruned shoots at June, whereas maximum Vitamin C was found in control guava fruits at May We can be recommended by apical 10 cm of pruning shoots at May to get the best results of yield, fruit growth and fruit quality.
Oxytocin modulates social brain network correlations in resting and task state

The effects of oxytocin (OT) on the social brain can be tracked upon assessing the neural activity in resting and task states, and developing a system-level framework for characterizing the state-based functional relationships of its distinct effect. Here, we contribute to this framework by examining how OT modulates social brain network correlations during resting and task states, using fMRI. First, we investigated network activation, followed by an analysis of the relationships between networks and individual differences. Subsequently, we evaluated the functional connectivity in both states. Finally, the relationship between networks across states was represented by the predictive power of networks in the resting state for task-evoked activities. The differences in the predicted accuracy between the subjects displayed individual variations in this relationship. Our results showed that the activity of the dorsal default mode network (DDMN) in the resting state had the largest predictive power for task-evoked activation of the precuneus network (PN) only in the OT group. The results also demonstrated that OT reduced the individual variation in PN in the prediction process. These findings suggest a distributed but modulatory effect of OT on the association between resting and task-dependent brain networks.
ASSESSMENT OF F1 PROGENIES OF SWEETPOTATO (Ipomoea batatas (L.) Lam) FOR YIELD AND SUSCEPTIBILITY TO SWEETPOTATO WEEVIL (Cylas puncticollis) UNDER RAINFED CONDITION IN UMUDIKE, NIGERIA

Poor storage root yield and incidence of sweetpotato weevil Cylas puncticollis constitute major constraints to sweetpotato production in Nigeria. The objective of this study was to assess newly developed progenies of sweetpotato and identify promising genotypes with high storage root yield and resistance to Cylas spp. For this purpose, a field experiment was conducted at the National Root Crops Research Institute, Umudike, Southeast Nigeria during the 2015 and 2016 cropping seasons to evaluate diversity across progenies of different sweetpotato families, namely: SautiX442162 (6), SautiXLigri (5) and Sauti Poly Cross (10), including two national check varieties (Umuspo 3 and TIS 87/0087). This experiment was laid out in a randomized complete block design with three replicates. In this study, progenies of sweetpotato exhibited morphological variability storage root characters. SautiXLigri/4 (13.33t/ha) and SautiX442162/1 (12.70 t/ha) produced higher fresh storage root yield than the national check (Umuspo3) while five genotypes; SautiXLigri/4 (13.33t/ha), SautiX442162/1 (12.70 t/ha), SautiX442162/5 (12.03 t/ha), SautiX442162/2 (11.04t/ha) and Sauti PC/9 (9.97t/ha) produced higher fresh storage root yield than the national check (TIS 87/0087). Among the twenty one genotypes evaluated, nine genotypes; SautiX442162/5, SautiX442162/3, SautiX442162/2, SautiXLigri/2, Sauti PC/4, Sauti x 442162/1, Sauti PC/1, Sauti PC/5, Sauti x 442162/6 were susceptible to the attack of C. puncticollis. Sautix442162/5 had the highest attack of C. puncticollis, followed by Sautix442162/3 and Sautix442162/2 while twelve genotypes; Sauti PC/2, Sauti PC/3, Sauti PC/6, Sauti PC/7, Sauti PC/8, Sauti PC/9, Sauti PC/10, SautiX442162/4, SautiXLigri/1, SautiXLigri/3, SautiXLigri/4, SautiXLigri/5 did not record attack of C. puncticollis. This suggests that these genotypes may possess resistance genes and could be incorporated in breeding programs to produce hybrid varieties that are high yielding and resistance to Cylas puncticollis.
Writing-to-learn in introductory materials science and engineering

We examine the impact of writing-to-learn (WTL) on promoting conceptual understanding of introductory materials science and engineering, including crystal structures, stress–strain behavior, phase diagrams, and corrosion. We use an analysis of writing products in comparison with pre/post concept-inventory-style assessments. For all topics, statistically significant improvements between draft and revision scores are apparent. For the stress–strain and phase diagram WTL assignments that require synthesis of qualitative data into quantitative formats, while emphasizing microstructure-properties correlations, the highest WTL effect sizes and medium-to-high gains on corresponding assessments are observed. We present these findings and suggest strategies for future WTL design and implementation.
Thorax and abdomen body segment inertial parameters adjusted from McConville et al. and Young et al.

Body segment inertial parameters (BSIPs) are essential in biomechanics and regressions, in particular scaling equations based on segment lengths, are one of the most practical methods to obtain them. Adjustment of the BSIPs from McConville et al. and Young et al. has been previously proposed to define BSIPs and segment lengths based on joint centres. However, due to the unavailable estimation of the thoracic joint centre, the trunk was previously segmented into two segments: pelvis and torso, restricting the possible applications to movements with limited flexion or bending of the trunk. This short communication presents an update of the adjustment procedure to obtain the BSIPs of the thorax and abdomen segments. The thoracic joint centre is obtained by interpolation based on literature data and allows the computation of the relevant abdomen and thorax segment coordinate systems and segment lengths. The updated scaling equations may be useful for researchers who would like to use the adjusted BSIPs with a more detailed trunk definition.
PERFORMANCE ASSESSMENT OF TWO- WHEEL TRACTOR ON A LOAMY SAND SOIL OF ILORIN

Field performance evaluation of a 9kW two-wheel tractor has been carried out. Field operations carried out include: disc ploughing, mould board ploughing, cultivation, cultivation cum planting and harvesting; following the types of accompanying implements available. The parameters measured and determined for each case included area of land covered, average time of operation, fuel consumption, width of action, average depth of cut, wheel slippage, speed of operation, field capacity and field efficiency. Field efficiencies determined were: 53.98% for disc ploughing, 88.30 % for mould board ploughing, 66.63 % for cultivation, 81.26% for cultivation cum planting and 72.88% for harvesting with a reaper. It was therefore concluded that power- tillers as they are commonly called are better alternatives when compared to animal drawn equipment for several field operations like tillage, planting, harvesting and transportation. This is true especially when looking at the average power work animal can sustain for a given time duration on the field. Also when considering the problems and cost of animal health and feeding.
Design and Behavior of Dapped-End Beams

T dapped-end beam is a useful concept. It enables the construction depth of a precast concrete floor or roof structure to be reduced, by recessing the supporting corbels into the depth of the beams supported. In a "cantilever and suspended span" type of structure, the suspended span is a dapped-end beam, and the ends of the supporting cantilevers are similar to the ends of the dapped-end beams, but inverted. The use of dapped-end beams facilitates the erection of a precast concrete structure, due to the greater lateral stability of an isolated dapped-end beam than that of an isolated beam supported at its bottom face. Despite the fairly extensive use made of this form of construction, few studies 1' 2 appear to have been made of its behavior. These were primarily analytical, utilizing the finite element method to analyze the stresses in and around the dapped end under service load conditions. From these analyses, Werner and Dilger2 were able to predict the shear at which diagonal tension cracking would occur at the re-entrant corner. They also proposed that the shear strength of the dapped end could be calculated using:
The Role of Independend Commisioners in Moderating the Effect of Profitability, Company Size and Company Risk on Tax Avoidance

The purpose of this study was to determine and analyze the the role of Independent Commissioners in moderating the effect of profitability, company size, and company risk on tax avoidance in manufacturing companies on the Indonesia Stock Exchange period 2016-2018 with a total of 77 companies. The sampling technique in this study used a purposive sampling technique with a total observation are of 231 firm-years. With multiple regression analysis, this research showed that the Company’s Profitability and Risk had a significant positive effect on Tax Avoidance, while Company Size did not have a significant effect on Tax Avoidance. The Independent Commissioners succeeded in weakening the positive influence of profitability and company risk on tax avoidance.This research succeeds in proving that as a component of the corporate governance mechanism, the Independent Commissioner has a role in supervising managerial decisions, including tax decision.
Hilbert-Huang transform-based transient busbar protection algorithm

A new algorithm for busbar protection is proposed based on the Hilbert–Huang transform in this study. The algorithm decomposes currents of all lines connecting to the busbar into intrinsic-mode functions and calculates the instantaneous amplitude of the first intrinsic mode function (IMF). Then, the instantaneous amplitude is normalised to eliminate the impact of fault initial angle and transition resistance. When a fault occurs on the busbar, the initial travelling waves on head ends of the lines all have great instantaneous amplitudes; when a fault occurs on any line, the travelling wave on the faulted line is of great instantaneous amplitude, whereas the initial travelling waves on healthy lines are of small instantaneous amplitudes. Thus, through analysing the detected instantaneous amplitudes of travelling waves, a new busbar protection scheme can be constructed, which achieves a high reliability relative to other fault-travel-wave-based algorithms. According to simulation results on a 500 kV substation modelled in ATP-Draw, the graphical preprocessor to ATP-EMTP windows version, the proposed algorithm is effective in determining various types of faults.
“Just a Pepper in a Bunch of Salt”: Aboriginal Students’ Stories of School

Mirroring national trends, the Saskatchewan education system is failing its Aboriginal students. The situation is urgent, evidenced by low rates of Aboriginal students transitioning through the grades, their lower results on provincial assessments, and the significant gap between Aboriginal students and their non-Aboriginal counterparts graduating from high school. In light of these issues, this research explores high-school aged Aboriginal students’ stories of school and in particular their stories of place, curriculum, teachers and administrators. The research recognizes schools as white spaces where dominant identities are affirmed through place, spaces, curriculum, and pedagogy. Data was collected through four semi-structured interviews with five adolescents who self-identified as Aboriginal. A Critical Race Theory framework, with its emphasis on counter stories, was used to analyze the data, paying particular attention to the reproduction of dominance. The stories of these five participants highlight the need for teachers and administrators, the majority of whom are White, to take actions to promote the success of Aboriginal students in the classroom. Important to the participants is the creation of a sense of belonging to a place through the inclusion of Aboriginal artifacts and the actions of teachers to support those objects in meaningful ways. Additionally, the students articulate that teachers should authentically infuse Aboriginal content throughout core curriculum. Finally, teachers and administrators need to overcome their disconnect with Aboriginal students by developing close personal relationships with them and engaging in processes of decolonization through critical self-reflective work.
APPLICATION OF THE SELF-DIRECTED LEARNING (SDL) LEARNING MODEL IN ENVIRONMENTAL ENGINEERING COURSES FOR STUDENTS OF THE BUILDING ENGINEERING EDUCATION STUDY PROGRAM, UNIVERSITY OF PALANGKA RAYA, ACADEMIC YEAR 2020/2021

Teachers must work on learning assignments from home (continuously and as a controlled routine) on an ongoing basis and have the potential to be unproductive to work in a completely new environment and without the supervision of a leader (intense). However, there are a number of ways to deal with this problem, especially preventing teachers from being confused in applying appropriate and effective learning models, as well as continuous professional development, they definitely want to be productive in utilizing their time during the Covid 19 pandemic. Time management must be carried out and controlled properly to improve quality. teacher professionalism as a professional educator. The solution, teaching staff is required to be able to design learning media as an innovation by utilizing online media (online). This research is motivated by the learning outcomes of Building Engineering Education students who program Environmental Engineering Courses are still relatively low below a score of 60 (C value). Self-Directed Learning (SDL) is learning in which the conceptualization, design, implementation and evaluation of learning projects are directed by students. The key point is whether students choose to concentrate on learning. This type of research is classroom action research which is carried out online, this is due to the ongoing covid-19 pandemic. Quantitative data in the form of numbers or scores obtained from student learning outcomes tests. The instrument used in this research is the final test of student learning outcomes. The parameters in this study are the learning outcomes and independence of Building Engineering Education students in the Environmental Engineering course. Plans or targets will be published in the Balanga Journal.
A 5-Year Multidisciplinary Care Outcomes in Children with Wilms’ Tumour Managed at a Tertiary Centre: A Retrospective Observational Study

Background: Over the last two decades, there has been significant improvement in the outcomes of children with Wilms' tumour (WT) in high income countries (HICs) with approximately 85% survival rate globally. This is partly attributable to a multi-disciplinary team approach to care and the evolution of more robust treatment measures. A previous review in our centre prior to multi-disciplinary team shows a survival rate of 31.48%, However, the survival rates from low- and middle-income countries are still low when compared to HICs due to delays in access to care at all levels, poor to non-existent health insurance coverage, limited workforce resources, weak health-care systems and infrastructure. The aim of this study is to determine the impact of a multi-disciplinary team approach on the treatment outcomes of children with WT. Methodology: This is a 5-year retrospective review of all patients managed with WT at the Lagos University Teaching Hospital, Lagos, Nigeria. Information was extracted from the patients' case notes, operation notes and ward admission records. The data were analysed with SPSS 25, and P < 0.05 was considered to be statistically significant. Results: Forty patients were included in the study; male to female ratio was 1.6:1. The disease occurred in the right kidney in 23 patients (57.5%) and on the left in 17 patients (42.5%). The average duration of symptoms before presentation was 3.6 months (range 1–7 months), majority of patients presented with abdominal masses and were assessed as per unit protocol with abdominal Computerized tomography scan, chest X-ray and abdominal ultrasound scan to assign the patient International Society of Paediatric oncology regimen. The predominant stage at surgery was Stage III 26 (65%), while Stage IV was 9 (22.5%). Morbidity after chemotherapy was 10 (25%). Twenty-five patients (63%) completed chemotherapy while 15 patients (37%) started chemotherapy but defaulted midway. The 5-year survival rate was 75%. Increasing age and male sex were associated with reduced odds of mortality; however, this was not statistically significant. Increased duration of treatment, being treated with chemotherapy alone, as well as advanced tumour stage and histology were associated with increased odds of mortality, however, this was not statistically significant. Conclusion: The development of an institutional WT treatment pathway involving a multidisciplinary team has resulted in improved outcomes. There is need for increased community awareness to improve the time to presentation.
Assessment of Risk Factors for Coronavirus Disease-2019 in Healthcare Workers: A Case–Control Study

Abstract Background and aims With the rise of coronavirus disease-2019 (COVID-19) cases globally, the infection among frontline healthcare workers (HCWs) escalates many folds. There is, however, limited literature from low middle-income countries regarding risk factors for COVID-19 infection in HCWs. We conducted a case–control study to evaluate the risk factors of COVID-19 infection to HCWs. Materials and methods This case–control study was conducted in a designated COVID-19 hospital. Eighty-one HCWs involved in direct care of COVID-19 patients, identified as cases, and 266 were recruited as controls. Telephonic interviews with participants were conducted, and information regarding demographic variables, chemoprophylaxis, exposure to infected patients, and adherence to infection prevention and control (IPC) measures was collected. Results We observed a statistically significant difference in the number of times training session for IPC measures attended by HCWs (p = 0.02), performance of aerosol-generating medical procedures (AGMPs) (p <0.001), practices of donning and doffing of personal protective equipment (PPE) (p <0.001), hand hygiene (p <0.001), and decontamination of highly touched surfaces (p <0.001). Logistic regression analysis revealed if the decontamination of highly touched surfaces is decreased by one unit, the odds of getting COVID-19 infection is multiplied by a factor of 0.41 and AGMPs decrease the risk of being a case by 0.76. Conclusion This study highlighted that inadequate observation of IPC methods increases the risk of COVID-19 infection to frontline HCWs, whereas performance of AGMPs does not enhance the risk. In this study, HCWs undertaking an AGMP, because of concern of acquiring infection, were more diligent during procedures and hence had lesser infection.
