Implementation of Inclusive Education Practices for Children with Disabilities and Other Special Needs in Uganda

This study aimed to assess the factors that influence the effective implementation of inclusive education, taking into consideration learners with disabilities and other special needs. The study objectives focused on the following key aspects that directly influence the implementation of inclusive education: inclusive policies, attitudes, perceptions, curriculum issues, and learning environment. The study adopted a case study design and employed qualitative approaches in sampling. Participants of the study (N=103) included special needs teachers (N=73) and learners with disabilities (N=30). Data collection was carried out through interviews. Some of the findings were positive, namely the policies on inclusive education were reported to be clear and well-suited to guiding the implementation practice, although some stakeholders were reported to be less committed. Attitudes towards learners with disabilities and other special needs were reported to be increasingly positive in the last decade. The findings on the perceptions of the ability and capability of learners with disabilities and other special needs to benefit from inclusive education drew a mixed reaction – some respondents reported that there were learners who were able to benefit from inclusive settings, while others were not. On the subject of the curriculum, the results revealed that some learners with disabilities and other special needs were capable of benefiting from the regular curriculum, while others would benefit from a special curriculum. Lastly, with regards to environmental factors, the study revealed that adequate preparations were always made to provide a conducive environment for learning in inclusive education settings. A major recommendation was made to draw the attention of policy makers to support inclusive education, which ought to be treated as a right and not a privilege for learners with disabilities and other special needs. This study will help to enhance the effective implementation of inclusive education, taking into consideration disability issues. In regard to environmental factors, the study reveals that adequate preparations are required to provide a conducive environment for learning in inclusive settings. The paper proposes a need for support from all stakeholders to treat inclusive education as a right and not a privilege for learners with disabilities and other special needs.
Inductively coupled plasma reactive-ion etching of β-Ga2O3: Comprehensive investigation of plasma chemistry and temperature

The authors investigated the inductively coupled plasma reactive-ion etching (ICP-RIE) of β-Ga2O3 using different fluorine and chlorine-based plasmas. Sn-doped (-201) oriented β-Ga2O3 substrates were etched using SF6/Ar, CHF3/Ar, O2/Ar, BCl3/Ar, and Cl2/Ar based ICP-RIE. Appreciable etch rates were obtained only with chlorine and boron-trichloride based plasmas, and the authors performed a comprehensive study on the composition and temperature-dependence of ICP-RIE of β-Ga2O3 in BCl3/Cl2/Ar plasmas in a temperature range of 22 to 205 °C. In general, the etch rate decreased with increasing Cl2 content in BCl3/Cl2/Ar plasmas. A high etch rate of 144 nm/min with a smooth surface morphology was obtained in BCl3/Ar plasmas, compared to 19 nm/min in Cl2/Ar plasmas. The etching behavior of Ga2O3 shows more similarity to that of Al2O3 than to that of GaN.
THE ROLE OF URBAN SPACE CONFIGURATION IN MAINTAINING SOCIAL INCLUSION: A comparison of four types of neighborhoods in Greater Cairo Region-Egypt.

Since the mid-twentieth century, the process of modernization caused an adaptation of westernized prototypes of residential neighborhoods in Greater Cairo Region. This evolution caused a relevant evolution of various prototypes of urban spaces, an evolution from traditional neighborhoods where street works as public space to new planned neighborhoods that concern quantitative provision of urban spaces as internal gardens inside superblock. The evolution was attractive for residents who escaped crowded traditional neighborhoods and claimed quantitative provision of urban spaces with well-designed landscape to enjoy better living conditions. Egyptian National Organization for Urban Harmony developed urban space design guidelines, to ensure quantitative and accessibility criteria. However, observation of urban spaces in new cities revealed failure to host residents and probably have negative impacts on social inclusion, cohesion, and participation. One reason behind that failure is the lack of empirical knowledge of expected impacts of design guidelines on social behavior. This research examines social sustainability of urban space configuration in four prototypes of neighborhoods, it also questions how socially sustainable are NOUH2010 design guidelines. The research depends on ethnographic observation and questionnaire survey that were conducted in selected neighborhoods. The paper reports, based on empirical findings, that modern urban spaces with quantitative provision of urban-spaces, hierarchical distribution, merged and central location, good accessibility and well-designed landscape are short sighted to achieve urban social sustainability; rather qualitative mixed use is most influential factor to encourage social inclusion, interaction and participation as by-product of movement and as subsidiary to other attractive activities.
Investigation of the interaction between concrete-gypsum interface and internal notch using experimental test and numerical simulation

Abstract The experimental and discrete element method was used to investigate the interaction between concrete-gypsum interface and internal notch. Gypsum and concrete semi-circular samples with diameter of 10 cm and height of 10 cm were prepared separately. Then one gypsum sample and one concrete sample was attached to each other with glue. The middle space between gypsum–concrete interface has not any glue so one joint was built in this space. The length of joints were 2 cm, 4 cm, and 6 cm. In experimental tests, the joint direction related to loading axis change from 0° to 90° with increment of 30°. Totally, 12 experimental tests were performed. In numerical tests, the joint direction related to loading axis change from 0° to 90° with increment of 15°. Totally, 21 numerical tests were simulated. This testing show that the failure process is mostly governed by the joint direction related to loading axis. The tensile strengths of specimens are related to the fracture pattern and failure mechanism of the discontinuities and gypsum–concrete interface direction. The tensile behavior of discontinuity is related to the number of induced tensile cracks which are increased by decreasing the joint length. The tensile strength of samples decreases by increasing joint length. Their value was minimum when joint angularities were 30° and 45°. Failure pattern and failure strength are similar in both of the experimental test and numerical simulation.
Synthesis and Characterization of Graphene Oxide Under Different Conditions, and a Preliminary Study on its Efficacy to Adsorb Cu2+

Article history: Received: 22 August, 2020 Accepted: 30 October, 2020 Online: 10 January, 2021 Graphene oxide (GO) was prepared by the modified Hummer's method, but the mass ratio of graphite to sodium nitrate (NaNO3) was varied from 2:1, 1:1, and 1:2. The primary reason for the variation was to determine the optimum conditions that would afford more oxygen functional groups to improve the material for application in adsorption. The final products, termed GO2:1, GO1:1 and GO1:2, were analyzed by several instrumental techniques. The layered structure of the GO sheet was established by transmission electron microscopy, while powder X-ray diffraction showed that the GO2:1 material was more crystalline than either GO1:1 or GO1:2. Raman spectroscopy revealed the presence of a greater defect density in GO2:1. The presence of oxygen functional groups was verified by Fourier transform infrared spectroscopy, and these were quantified by the Boehm titration method. Overall, GO2:1 had a larger oxygen content than either GO1:1 or GO1:2, and a larger specific surface area. A preliminary study on the adsorption properties of the samples revealed that GO2:1 exhibited the highest percentage removal for Cu in aqueous solution. Thus, the preparation of graphene oxide with a smaller amount of NaNO3 yielded a material with a greater oxygen content, which showed suitable properties for the adsorption of contaminants in wastewaters.
Differentially Private Distributed Optimization via State and Direction Perturbation in Multiagent Systems

This article studies the problem of distributed optimization in multiagent systems where each agent seeks to minimize the sum of all agents’ objective functions using only local information. Under the requirement of security, each agent needs to keep its objective function private from other agents and potential eavesdroppers. We first prove the impossibility of guaranteeing convergence and differential privacy simultaneously by perturbing states in exact distributed optimization algorithms. Motivated by this result, we design a completely distributed algorithm, Distributed algorithm via Direction and State Perturbation (DiaDSP), that achieves differential privacy by perturbing both states and directions with decaying Laplace noise. Different from most of the existing works that require decaying stepsizes to ensure convergence, we show that our DiaDSP algorithm converges in mean and almost surely even with a constant stepsize. In particular, we prove linear convergence in mean by only assuming that the sum of all cost functions is strongly convex. The R-linear convergence is proved under the assumption of Lipschitz gradients instead of that of bounded gradients. The optimal stepsize for the fastest convergence rate is also established. Moreover, we describe the privacy properties and characterize the tradeoff between differential privacy and convergence accuracy. Simulations are conducted on a typical sensor fusion problem to validate the theoretical results.

Effects of resveratrol on secondary spinal cord edema and activity of lactic dehydrogenase and ATPase in experimental spinal cord injury of rats

AIM To study the effects of resveratrol on secondary spinal cord edema and the activity of lactic dehydrogenase and Na +, K + ATPase in experimental spinal cord injury (SCI)rat. METHODS The weight dropping method was used to produce the experimental spinal cord injury in adult rats. Resveratrol (Res) and methylprednisolone (MPSS) were intraperitoneally by the bolus injections of 50 mg·kg -1 , 100 mg·kg -1 and 100 mg·kg -1 , respectively, immediately after the induction of SCI. And then the effects of Res were observed at 1 h, 24 h, 48 h after SCI compared with MPSS. RESULTS Res could obvious inhibit the secondary spinal cord edema with the most remarkable suppressing rate by 11 5% at 48 h. Res was able to significantly suppress the activities of the lactic dehydrogenase with the highest suppressing rate for over 40% at 24 h. In the meantime, Res markedly improved the Na +, K + ATPase activities that promoted to the biggest extent to 60% at 48 h. The effects of Res were the same as or even stronger than those of MPSS. CONCLUSION Res may effectively protect the spinal cord from secondary spinal cord edema and improve the energy metabolism system in SCI. It suggested that Res may be having potent therapeutic effect on SCI.
Étude de la Morphologie et des Propriétés de Biocomposites Poly(3-Hydroxybutyrateco- 3-Hydroxyvalerate) (PHBV)/Farine de Grignons d’Olive

Ce travail a pour objectif de developper des biocomposites a base de poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) et de farine grignons d'olive (FGO) prepares par melange fondu. Il s'articule autour de quatre parties. La premiere partie comprend une etude de la morphologie et des proprietes physiques des echantillons biocomposites PHBV/FGO aux taux de charge de 10, 20 et 30% en masse. Les resultats indiquent que le systeme PHBV/FGO se caracterise par une separation de phase dont le nombre et la taille des particules de FGO augmentent avec le taux de charge. De plus, la stabilite thermique et les proprietes barrieres vis a vis de la vapeur d'eau et de l'oxygene ont diminue. Par contre, l'incorporation de la FGO dans le PHBV induit une augmentation du module d'Young qui s'accentue avec le taux de charge. La meme tendance est egalement observee avec le module de conservation determine par DMA. Dans la seconde partie, l'impact du PHBV-g-MA comme agent compatibilisant dans les biocomposites PHBV/FGO a ete evalue en fonction du taux de charge. La caracterisation morphologique du systeme ternaire a revele que la presence du PHBV-g-MA dans les biocomposites PHBV/FGO induit une meilleure adhesion interfaciale entre les particules de la FGO et la matrice PHBV en raison des interactions charge-matrice. En consequence, une nette amelioration des proprietes mecaniques, viscoelastiques et barrieres aux gaz (vapeur d'eau et oxygene) est observee. Dans la troisieme partie, une modification chimique de la FGO avec le trimethoxy (octadecyl)-silane (TMOS) et son influence sur la morphologie et les proprietes physiques de biocomposites PHBV/FGO: 80/20 ont ete etudiees. Les resultats revelent une dispersion fine et homogene de la FGO traitee au TMOS dans la matrice PHBV avec en apparence moins de microvides en comparaison avec le biocomposite non modifie. Les proprietes physico-mecaniques du biocomposite PHBV/FGO modifiee sont sensiblement ameliorees. La derniere partie consacree a une etude du vieillissement hygrothermique dans l'eau de mer a 25 et 40°C de films de biocomposites PHBV/FGO: 80/20 avant et apres modification, revele que la FGO favorise la cinetique de degradation du systeme PHBV/FGO independamment du traitement. Toutefois, le biocomposite PHBV/FGO traite avec des organo-silanes se caracterise relativement par une resistance a la degradation hygrothermique a 25 et 40°C par rapport au reste des echantillons biocomposites.
Prevalence of insomnia in shift workers: a systematic review

Insomnia is a sleep disorder of high prevalence with somatic and psychic repercussions. The present study aimed to describe the prevalence of insomnia in shift workers, as well as the associated variables: gender, age, marital status, profession and shift work schedule. A systematic review was performed using the descriptors “insomnia” AND “shift work”, in the PubMed, SciELO and LILACS databases, including studies that presented frequency of insomnia in shift workers, published between 2000 and 2020, in English or Portuguese, only in individuals over 18-years-old. Review articles, meta-analyzes, studies without socioeconomic information, articles without abstract and articles with participants who presented other comorbidities that justified presence of insomnia or pregnant women were excluded. From 480 studies identified, 5 were included in the analysis, with a total sample of 10,141 participants, of whom 4,183 were shift workers. The prevalence of insomnia in shift workers ranged from 12.8% to 76.4%, higher than estimated for general population. Moreover, a higher prevalence was observed among women and singles, and there was no significant variation with age and profession. On the other hand, a relationship between shift work schedule and onset of insomnia still seems controversial.
Ventajas y límites de la variabilidad morfofisiológica para el establecimiento, la colonización y la expansión del bivalvo invasor Limnoperna fortunei en Sudamérica

Phenotypic variability, both based on phenotypic plasticity and genetic diversity, can be a main factor affecting the invasion process of alien species. Limnoperna fortunei (Dunker 1857) was introduced in South America around 1990, in the Rio de la Plata estuary, Argentina, from where it spread swiftly to cover most of the basin and other smaller watersheds. However, some environments have not been colonized and, presumably, the survival of this species was affected by different environmental factors such as suspended solids, salinity, and pollution. L. fortunei showed high genetic and morphological variability, showing a distribution strongly affected by human activities and its dispersal vectors. The degree of phenotypic variability would be playing a main role in its establishment, or not, in the different environments. Morphological and metabolic variations, including changes in the growth rate, development of internal organs or changes in the rate of filtration and respiration in border areas of its distribution or under extreme environmental conditions, would allow to explain, together with other variables such as the presence of dispersal vectors, the current distribution pattern.
Wind integrated power system to reduce emission: An application of Bat algorithm

The trend of increasing demand creates a gap between generation and load in the field of electrical power systems. This is one of the significant problems for the science, where it require to add new generating units or use of novel automation technology for the better utilization of the existing generating units. The automation technology highly recommends the use of speedy and effective algorithms in optimal parameter adjustment for the system components. So newly developed nature inspired Bat Algorithm (BA) applied to discover the control parameters. In this scenario, this paper considers the minimization of real power generation cost with emission as an objective. Further, to improve the power system performance and reduction in the emission, two of the thermal plants were replaced with wind power plants. In addition, to boost the voltage profile, Static VAR Compensator (SVC) has been integrated. The proposed case study, i.e., considering wind plant and SVC with BA, is applied on the IEEE30 bus system. Due to the incorporation of wind plants into the system, the emission output is reduced, and with the application of SVC voltage profile improved.
Machine Learning for Identifying Group Trajectory Outliers

Prior works on the trajectory outlier detection problem solely consider individual outliers. However, in real-world scenarios, trajectory outliers can often appear in groups, e.g., a group of bikes that deviates to the usual trajectory due to the maintenance of streets in the context of intelligent transportation. The current paper considers the Group Trajectory Outlier (GTO) problem and proposes three algorithms. The first and the second algorithms are extensions of the well-known DBSCAN and kNN algorithms, while the third one models the GTO problem as a feature selection problem. Furthermore, two different enhancements for the proposed algorithms are proposed. The first one is based on ensemble learning and computational intelligence, which allows for merging algorithms’ outputs to possibly improve the final result. The second is a general high-performance computing framework that deals with big trajectory databases, which we used for a GPU-based implementation. Experimental results on different real trajectory databases show the scalability of the proposed approaches.
Effects of Carbon Ion Beam Irradiation on Phenotypic Variations and Biochemical Parameters in Early Generations of Soybean Plants

Understanding the characteristics of carbon ion beam irradiation-induced mutation is essential to its potential application in plant breeding. A carbon ion beam-mutagenized soybean population was generated from the newly released soybean variety Dongsheng 28, with irradiation dosages of 100 Gy, 120 Gy and 140 Gy. Many phenotypic variations and novel mutants with heritable tendencies including plant height mutants, sterile mutants, early mature mutants, rolled leaves and short petioles mutants, yield-related mutants and lodging-resistant mutants were identified. Diverse variations in seed size, seed protein and oil concentration were found. Increasing irradiation dosage from 100 Gy to 140 Gy increased leaf chlorophyll concentration in M1 generation, but this effect was significantly reduced in M2 generation. The activities of superoxide dismutase (SOD), peroxidase (POD) and malondialdehyde (MDA) concentration all showed wider variation in M1 and M2 generation, the only exception being that the MDA concentration was similar to the control in the M2 generation. Overall, we suggest that treating soybean seeds with carbon ion beam irradiation at a dosage of 120 Gy (80 Mev/u) could be effective in soybean mutation breeding.
A study of perceived benefits of mentoring among nascent entrepreneur women: the case of ‘MET’ mentoring community in Spain

The purpose of this paper is to identify to what extent novice/nascent entrepreneur women perceive that their participation in a mentoring programme contributes positively to their personal/professional development in terms of benefits derived. A quantitative methodology was used to gather information on perceptions/opinions of participants in a ‘MET’ mentoring community programme placed during academic years 2014-2015 to 2016-2017. The acronym corresponds to the concepts of Women (Mujer in Spanish), Entrepreneurship and Technology. Results show that due to the programme, women perceive themselves competent in relation to the competence analysed; show a high level of job satisfaction and degree of progress; identify new business opportunities, expand their vision, improve their business performance, achieve their goals, and transform their business project.
