Slowly but surely: The substantive approach to the right to basic education of the South African courts post-Juma Musjid
Authors: Arendse Lorette
Published: October 2020

This article assesses the extent to which the South African Constitutional Court's seminal findings in Governing Body of the Juma Musjid Primary School v Essa NO have bolstered the lower courts to give tangible content to the right to basic education. It is contended that the particular facts of Juma Musjid, which required the Constitutional Court to rule on the negative obligations of section 29(1)(a) of the Constitution, actually played a significant role in the Court's unequivocal pronouncement that the right is unqualified. The Court's ruling on the nature of section 29(1)(a) seems to have emboldened lower courts to adopt a substantive interpretation of the right. The article traces the lower courts' judgments over a period of almost a decade and explores in detail how the right to basic education has been 'filled out' incrementally by these courts. The connection between the incremental approach and a conceptualisation of transformation that is cognisant of the changing context of our society is also explored in the article. It is argued that a case-by-case approach to litigating potential violations of the right to basic education ensures that the right is never fixed but keeps on evolving to keep abreast of changing forms of (in)justice in our society.
The case law of the African Court on Human and Peoples' Rights in Libya following the Arab uprisings: Lessons learned for the consolidation and legitimation of the Court
Authors: Rodríguez Juan Bautista Cartes , Álvarez Laura Íñigo
Published: October 2020

This article examines the two cases brought before the African Court on Human and Peoples' Rights following the Libyan uprising in 2011: African Commission on Human and Peoples' Rights (Benghazi) v Libya and African Commission (Saif al-Islam Gaddafi) v Libya. These two cases mark three 'firsts': the first time for the African Commission to transfer a case to the African Court; the first order for provisional measures by the Court; and the first time the Court rendered a judgment by default. This study reveals that although the Court has taken significant steps in terms of its consolidation and legitimation, substantive and procedural challenges in its functioning remain. Moreover, the authors argue that the political divisions within the African Union diminished the Court's potential impact on the Libyan crisis.
Using the right to health framework to tackle non-communicable diseases in the era of neo-liberalism in Uganda
Authors: Twinomugisha Ben Kiromba
Published: October 2020

The main objective of this article is to reflect on how the right to health framework may be used to tackle non-communicable diseases in the era of neo-liberalism in Uganda. NCDs, also known as chronic or lifestyle diseases, cause many deaths. The risk factors for NCDs include the harmful use of alcohol, physical inactivity, salt intake, tobacco use, raised blood pressure, diabetes, obesity, as well as ambient and household air pollution. The article moves beyond the recognition of these important risk factors and interrogates the contribution of neo-liberalism to the prevalence of NCDs. The article argues that neo-liberalism, which emphasises the role of market forces in dealing with socio-economic questions, significantly contributes to the NCDs challenge in Uganda. The article concludes that the right to health can and should play a critical role in tackling the challenge of NCDs in Uganda. Unless policy challenges associated with neo-liberalism are tackled, current NCD prevention, control and management efforts that focus on individual behaviour or lifestyle approaches and place the burden of responsibility on the individual may not achieve the desired results.
Rethinking the right to water in rural Limpopo
Authors: Maziwisa Michelle Rufaro , Lenaghan Patricia
Published: October 2020

For decades Africa has been losing billions of dollars every year as a result of illicit financial flows. When export and import figures are tampered with this has the tendency to erode the tax base. It is common cause that in Africa a large percentage of state revenue emanates from taxation. The consequence of tax base erosion is that the government has less revenue. With less revenue, the government is increasingly unable to provide social services. The consequences for women are particularly dire as women have to end up subsidising the state in providing services, reproductive and care work. This article argues that the government has a responsibility to ensure that the maximum 'available resources' are allocated to the attainment of socio-economic rights, particularly the right to water, especially for the poorest in the country. The article is limited in scope to the province of Limpopo in South Africa. The article highlights the impact of illicit financial flows (IFFs) on women and girls living in rural communities, particularly in Limpopo. It sets out the nature and extent of IFFs in South Africa, and describes the socio-economic context of Limpopo and the extent to which the right to water has not been realised in selected rural parts of Limpopo. The article further outlines the relevant legal framework and finally analyses the gendered implications of the right to water and the duty on the state.

Published: October 2020

Цель: построение комплекса моделей, обеспечивающего возможность многовариантных прогнозных расчетов социально-экономического развития региона. Обсуждение: многомерность и многовариантность это основные проблемы, которые необходимо преодолеть в прогнозных расчетах ожидаемого социально-экономического состояния региона. Модель, с помощью которой можно было бы решить обе проблемы, в настоящее время не известна. Разработка такой модели, по мнению авторов возможна на основе комбинирования эконометрического подхода с идеями многомерного прогнозирования на основе матричного предиктора. Важным моментом в реализации такого комбинированного подхода является способ, с помощью которого разнохарактерные модели удается объединить, придав результату объединения направленность на получение требуемого результата. Такой способ был получен путем специального представления авторегрессионной схемы моделирования. В окончательном варианте многомерность и многовариантность обеспечивается комплексом из трех моделей, две из которых, являясь вспомогательными, обеспечивают полноту информационного обеспечения комбинированной модели. Результаты: подробно изложена методика получения регрессионно-матричной модели в аналитическом виде, позволяющей осуществлять многовариантные расчеты многомерных процессов.

Authors: Payá Castiblanque Raúl , Pizzi Alejandro
Published: October 2020

La desregulación y precarización del mercado de trabajo ha derivado en un incremento de los riesgos y enfermedades de origen psicosocial en Europa en general, y en España en particular. Ante tal contexto, el objetivo de la presente investigación es evaluar el impacto de la representación sindical especializada (delegados de prevención) sobre la implementación de medidas de prevención de riesgos psicosociales en las empresas. A tal efecto, utilizamos la Segunda Encuesta Europea de Empresas sobre Riesgos Nuevos y Emergentes (ESENER 2 - España 2014). Comparamos los indicadores de gestión de riesgos psicosociales con la presencia o ausencia de delegados de prevención en las empresas. Estimamos las odds ratio a través de regresiones logísticas binarias ajustadas mediante variables sociodemográficas. Los resultados obtenidos muestran que en los centros de trabajo que cuentan con delegados de prevención se realiza con mayor prevalencia evaluaciones de riesgos psicosociales, tanto en aspectos relacionales como organizativos. También la presencia de delegados de prevención se relaciona positivamente con el establecimiento de planes y procedimientos para evitar el estrés laboral, así como amenazas, insultos o agresiones. Asimismo, promueve la formación y asesoramiento a los trabajadores ante dichos riesgos, y favorece la existencia de mecanismos para la resolución de conflictos. Pese a encontrar evidencia empírica de un impacto positivo de los delegados de prevención, se han identificado diferentes factores coyunturales, legales e institucionales que socavan los recursos de poder sindical (estructural, asociativo, institucional y social) y debilitan dicha correlación.

Published: October 2020

Engineering is one of the crucial parts of STEM Education. The Engineering Design Process (EDP) is a new trend within science education reform. Most science teachers lack information regarding the usage of EDP in learning science. This study aims to review 40 articles from reputable international journals such as indexed by Scopus and Web of Science (WoS), which explains the steps of the EDP used in science education. The articles selected for review were the ones published in the last ten years, from 2011 to 2020. Some previous literature review studies focused on the EDP through project-oriented capstone courses, the EDP in middle school settings, and how to implement the EDP in science learning. However, this study focuses on the steps of the EDP used in science education (Science, Physics, Biology, Chemistry, and a combination of science with other disciplines). In addition, this research also explains the strengths and weaknesses of EDP in science education. The research approach used was a systematic literature review. This study analyzed the representation of research according to their general characteristics consists of type of publication, year of publication, country, research approach, educational level, and science content. This study found that research on the EDP that is implemented at the university level is still limited, especially on subjects related to interdisciplinary knowledge. Furthermore, the steps of the EDP used in science education differ from one research to another. The most commonly used steps of the EDP are defining the problem, building, testing, evaluating, and redesigning. There are also several obstacles to the implementation of the EDP in science education. Regardless, the implementation has a positive influence on students, undergraduate students, teachers, or others. The results of this study provide an overview of how to implement the EDP in science education. Thus, it can be used as a reference for stakeholders in the field of science education when implementing EDP in their learning.

As a consequence, it’s use is widespreading for the treatment of atrial fibrillation, coronary events, deep vein thrombosis, pulmonary embolism etc. The overall risk of haemorrhage is considered lower with NOACs but instead the risk of gastrointestinal bleeding it seems to be rising in respect to the type of the anticoagulant, the dose, the clinical situations and other concurrent drug therapies. It is important to clarify any differences between the newer and classic anticoagulants regarding the severity of haemorrhage in respect to the important implications on the prognosis and economic burden of this adverse effects. Aim: Differences in severity of haemorrhage (χ2 test) Differences in the endoscopic findings and type of endoscopic interventions (χ2 test, anova) Comparison of epidemiologic clinical and laboratory findings during hospitalization (t-test, χ2) Analysis of risk factors causing severe haemorrhage (regression analysis) There will be comparisons even between the newer anticoagulants if the sample size is adequate Patients and Methods: The study will include consecutive patients with obvious gastrointestinal haemorrhage (melena, hematemesis, blood per rectum) or obscure bleeding (hypochromic microcytic anemia, iron deficiency) either as an emergency case or as hospital inpatients. The patients should follow anticoagulant therapy during the bleeding episode as a preventive measure against thrombosis. Patients with idiopathic inflammatory bowel disease or haemorrhage after polypectomies will be excluded from the study All patients will provide informed consent for the endoscopic and any interventional procedure. The endoscopies will follow the institutional protocols for the constrain of haemorrhage. Information will be collected from the endoscopic and histopathology report while epidemiologic clinical and laboratory investigations will be gathered in a special written form.

Authors: M G Srinivasa, P S Pandian
Published: October 2020

The variation of the heart rate about a mean value is the Heart Rate Variability (HRV). HRV reflects the functioning of cardio-respiratory control system. It is used as one of the diagnostic measures to detect heart disorders. In the proposed work, HRV analysis using entropy measures is carried out on healthy, Congestive Heart Failure (CHF) and Atrial Fibrillations (AF) subjects using their ECG signals. The entropy methods used in the work are Approximate entropy (ApE), Symbolic entropy (SyE) and Spectral entropy (SpE). ECG signals of 20 healthy subjects in the age group of 21 – 30 years were acquired using dry electrode at a sampling rate of 500 Hz for 10 minutes. Signal processing algorithms for removal of baseline wandering, power line interference and motion artefacts were applied for the raw ECG signal. The ECG signals for CHF and AF subjects in the age group of 30 – 75 years were obtained from the Physionet database. From the analysis it was found that values of ApE and SyE were highest for AF subjects and for SpE, the value was highest for healthy subjects. Further, values of all the three entropies were lowest for CHF subjects. In conclusion, it indicates that the entropy techniques are useful tools in diagnosing patients having heart disorders.

Published: October 2020

The Internet of Things (IoT) is a new interconnection of technology. It is being heralded as the next industrial revolution. It’s also praised for its ability to reduce waste and energy, by allowing us to better control our use of resources based on our actual needs. Currently, energy consumed by the street lights in metropolitan cities is extremely high and hence are less efficient. One of the major problems with the existing street lighting system is that all the street lights are controlled manually and therefore require huge manpower. Even if a street light stops working there is no way by which the authorities can know about the failure. Another growing concern in cities is the pollution. The purpose of this paper is to propose a solution which can be adopted in every city where all the street lights are connected to the central server via internet which can be monitored remotely and thus making it an energy efficient system. These street lights are adaptive meaning that they can change the intensity of light depending on the vehicular movement. They also send information about the pollution level in that locality. Thus IoT promises huge improvements in street lighting system.

Authors: Sonia Salaria, Anil Sagar, Baljinder Singh
Published: October 2020

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth restricted wireless links. Since the nodes in topology are mobile, the network might change rapidly and unpredictably with time. Due to mobility of nodes in a network, the path stability is disturbed and hence the link breakage occurs. In this paper, an estimated time based stable routing methodology is proposed with the help of flowchart, which further will improve breakage of link and hence the lifetime of the network will increase considerably.

Published: October 2020

A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth restricted wireless links. Since the nodes in topology are mobile, the network might change rapidly and unpredictably with time. The network is decentralized; where all network activities including discovering the topology and delivering messages must be executed by the nodes themselves i.e. route discovering functionality will be incorporated into mobile nodes. But, due to mobility of nodes in a network, the path stability is disturbed and hence the link breakage occurs. In this research work, the signal strength is continuously measured till the node go out of range. Then, time is noticed and if time limit is below threshold value, then the path is not selected. On the other hand, if the value of time limit is above threshold, the path is selected and hence the less breakage occurs in that case.

Authors: P M Bhatt
Published: October 2020

Increasing industrialization and motorization led to a significant rise in demand of petroleum products. As these are the non-renewable resources, it will be troublesome to predict the availability of these resources in the future, resulting in uncertainty in its supply and price and is impacting growing economies like India importing 80% of the total demand of the petroleum products. Many attempts have been made by different researchers to find out alternate fuels for Internal Combustion engines. Many alternate fuels like Biodiesel, LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas) and Alcohol are being used nowadays by different vehicles. In this context pyrolysis of scrap tyres can be used effectively to produce oil, thereby solving the problem of waste tyre disposal. In the present study, Experimental investigations were carried out to evaluate the performance and emission characteristics of a single cylinder diesel engine fueled by TPO10, TPO15, and TPO20 at a crank angle 280 before TDC (Top Dead Centre) and injection pressure of 180 bar keeping the blend quality by controlling the density and viscosity of tyre pyrolysis oil within permissible limit of euro IV diesel requirement. The performance and emission results were analyzed and compared with that of diesel fuel operation. The results of investigations indicate that the brake thermal efficiency of the TPO - DF blend decreases by 4 to 8%. CO emissions are slightly higher but within permissible limit of euro IV emission standards. HC emissions are higher by about 40 to 60% at partial load whereas smoke opacity is lower by about 14% to 22% as compared to diesel fuel.

Published: October 2020

This project demonstrates the creation of a robot using low cost light controlled variable resistor to follow a flash light. It also demonstrates a very simple control loop. A control loop is an important concept in the world of robotics. Control loops are used for everything from regulating the speed of the motors to helping the robot travel in the path of higher luminescence across all directions. It is based on the principle that resistance of a LDR changes with the amount of light falling on it. The resistance of an LDR will decrease with increase in luminescence. This variation is fed to a comparator with a reference voltage set. This drives the robot in the desired direction with the help of DC motors.

Published: October 2020

Biometrics is the technical term for body measurements and calculations. Biometric technology refers to identification and verification of individuals by analyzing the human body characteristics. In modern times, there has been an increase in the number of identity theft experienced on a day to day basis. Companies, Organizations and Institutions are generally concerned over the levels of employee absence in the workplace, where security is essential, access to restricted areas are controlled and monitored through a system. Most institutions find it hard to managing student’s attendance during lecture periods. Manually taking attendance by hand and preserving it over a long period adds to the difficulty and wastes a lot of time. For these reasons an effective system is proposed in this paper to solve the problem of manual attendance. Here a system would take attendance electronically with the help of a fingerprint recognition system and all records are saved in cloud or locally in the device. A staff biometric attendance would contain a system to calculate attendance of the staff and do further calculations such as monthly attendance summary and calculate wages based on attendance, etc. In addition, this system if implemented properly could increase productivity, can reduce truancy, lateness in organization and institution.

A Novel Digital Signature based on Error Correcting Codes
Authors: Younes Bayane, Fatima Amounas, Lahcen El Bermi
Published: October 2020

A digital signature is a cryptographic primitive for ensuring the authenticity of digital documents. A valid digital signature allows checking that a message was created by a known sender (authentication), that the sender cannot deny having sent the message (nonrepudiation), and that the message was not altered in transit (integrity).The idea of constructing practical signatures based on error correcting codes was introduced by Courtois et al in [1]. The main goal is to make digital signature for which the security is based on decoding syndrome problem. In this paper, a new construction of digital signature is considered which is an extension of the error correcting code construction. The proposed method consists of reordering the message bits to get a decodable word. Then apply an efficient decoding algorithm to get signature.

Published: October 2020

Emotion is a key element in user-generated video. However, it is difﬁcult to understand emotions conveyed in such videos due to the complex and unstructured nature of user-generated content and the sparsity of video frames expressing emotion. In this paper, for the ﬁrst time, we propose a technique for transferring knowledge from heterogeneous external sources, including image and textual data, to facilitate tasks in understanding video emotion recognition. After that the audio files are played based on the emotion in the video frames. Speciﬁcally, our framework (1) learns a video encoding from an auxiliary emotional image dataset in order to improve supervised video emotion recognition. A comprehensive set of experiments on multiple datasets demonstrate the effectiveness of our framework. At first the video is separated into number of frames. Then the separated frames are taken for the analyzing using Convolutional Neural Network (CNN). The process is used to analysis the video frames to identify the emotion that describe in the videos. After that the audio files are played based on the emotion in the video frames. As a result, after processing the frames through CNN layers it provides a sound clip according to each emotions.

In this study, we implement various ranking methods to test the efficiencies of a wide range of GMPEs against the recordings from three of the largest magnitude inland earthquakes that occurred in the Korean Peninsula, which belongs to an intraplate region with low seismicity. In this context, we select a total of 14 GMPEs developed for active shallow crustal zones (Next Generation Attenuation-West2 [NGA-West2] project), stable continental regions, and Korea. Three statistical approaches, including the classical residual, log-likelihood (LLH), and Euclidean distance-based ranking (EDR) methods, are used to evaluate the performance of the GMPEs. The residual analyses show that for the very short spectral period (T≤0.1  s), regionally developed GMPEs perform the best, whereas the NGA-West2 GMPEs outperform other equations for short (0.2≤T≤0.5  s) and medium to long periods (T≥0.75  s). The LLH approach is shown to favor a stable continental region GMPE that has the highest standard deviation. The EDR method, which can account for both aleatory uncertainties and model bias, is found to favor the NGA-West2 and Korean GMPEs. NGA-West2 GMPEs show the lowest model bias, whereas the Korean GMPEs exhibit the lowest residual bias. Five GMPEs selected based on the EDR method are recommended for a probabilistic seismic hazard analysis in Korea. For deterministic hazard assessment, using the Korean GMPEs for the very short spectral period and NGA-West2 GMPEs for short and medium to long periods is recommended. Overall, the stable continental region GMPEs are demonstrated to perform poorly when tested against the earthquakes recorded in Korea.

Background: The objective of the research was to evaluate the incidence of retinopathy of prematurity (ROP), association of prenatal and postnatal risk factors, pattern of ROP and treatment outcomes among infants admitted to neonatal intensive care unit (NICU) of tertiary care center located in Thiruvannamalai, Tamil Nadu.Methods: A retrospective study done in all infants admitted between April 2019 and March 2020 who met the criteria for ROP screening with gestational age (GA) less than or equal to 36 weeks or birth weight less than 2000 grams or with GA more than 36 weeks and birth weight more than 2000 gram with significant risk factors like intrauterine growth restriction, respiratory distress syndrome, sepsis, long term oxygen use, phototherapy, blood transfusion and maternal anemia. Treatment was offered to infants with stage 3 ROP and stage 2 in zone 2 with or without plus disease. Qualified infants were treated with argon laser photocoagulation within 72 hours of diagnosis. They were followed until the disease was successfully treated.Results: Out of total 3121 neonates, 717 neonates met the screening criteria. Incidence of ROP was found to be 33% (n=237). 46.4% (n=110) of ROP belongs to 32-36 weeks GA. 42.6% (n=101) of ROP belongs to 1500-2000 gm birth weight.Conclusions: Incidence of ROP is quite high in high risk neonates in our unit. Significant risk factors are long term oxygen use, blood transfusion and sepsis.

Background: The current study is focused on assessing the liver involvement of severely birth asphyxiated newborns, by measuring liver enzymes like Serum glutamic oxaloacetic transaminase (SGOT) and Serum glutamic pyruvic transaminase (SGPT) to predict the outcome of those babies. Methods: Total 111 severely birth asphyxiated newborns were assessed in a hospital based prospective analytical study. Liver enzymes were measured for all babies included in the study. Study subject details were obtained through a pre-structured questionnaire and also morbidity and mortality were noted. Analysis of the research data was done through appropriate statistical methods using SPSS version 20.Results: It was observed that incidence of hypoxic ischemic hepatitis, among entire study population was 34.2% (38 cases) based on SGPT (>100 U/l) values. Current study findings indicated that incidence of hypoxic ischemic hepatitis had a positive correlation with hypoxic ischemic encephalopathy (HIE) staging. Mean SGOT, SGPT values were observed to increase as the HIE staging progressed. Based on Spearman’s correlation coefficient evaluation, it was determined that the elevated SGOT and SGPT values had moderate positive correlation with HIE, seizure, ventilator support and death in the study population. It was found from the present study findings that statistically significant mortality (77.4%) was observed among the HIE stage III babies, with elevated SGPT values.Conclusions: Current study findings revealed that elevated SGOT and SGPT values (more than twice the normal) has high sensitivity to predict the outcome in severely birth asphyxiated newborns. The stated parameters can prove to be effective in counselling parents regarding morbidity and mortality of neonates due to birth asphyxia.

The article analyzes the definition of "methodology" in the context of various factors that make it difficult to understand it adequately, among which it is worth noting that the science of management is often presented and positioned only as a process of activity, without the process of thinking. The author's definition of the methodology is presented, which links the teaching about the management of thinking and activity on the basis of closely interacting attributes. It is shown that the methodology accumulates and offers a set of tools for solving problems and problems in any field of knowledge, including the field of management. Five groups of methodological tools are described: directive, creative, transformative, informative and evaluative, which have their purpose and content in the context of specific conditions for the study, construction and evaluation of the activities of various areas of functioning and development of economic systems of the "organization" type. The ontology of management science is shown which includes a set of attributes of all management science sections: theory, methodology, technology, as well as the main attributes of management practice. The novelty of the article is the approach to the formation of management science sections, the content of these sections, as well as some considerations for justifying their place in management for the activities of various types of systems in social and economic space.

The modern capabilities of intelligent systems make it possible to significantly expand the application of methods of structural-parametric data analysis in domain-oriented areas, which were previously considered the exclusive prerogative of specialists-experts with relevant experience and knowledge based on the ontology of these areas. There was no exception to the possibility of using programmatic analytical complexes in the field of profiling - obtaining characteristics and forecasting of personality behavior based on private characteristics, characteristics of physiology, non-verbal and verbal manifestations. The article proposes a system model of an intelligent profile system for managing personnel reserves, which opens up opportunities for both selections of personnel and effective training, and rotation of existing employees of the organization. To implement this model, a register of open information resources is determined. The system model corresponds to the structure of an expert system in which the formation of many solutions is present. The task is to ensure validation and verification of models taking into account uncertainty management. A software analytical complex has been developed, the implementation of which will make it possible to search and analyze data, form indicators for their subsequent use in decision-making in managing the organization's processes. Representation of knowledge about the studied subject area in the form of a system model allows the use of formal logical rules, graphicanalytical metalanguages and rules for the development and design of software analytical systems, to ensure ―electronic‖ transparency and openness in managerial, technological and other aspects. To implement this paradigm, state registers of open information resources are determined and created. The novelty of the results is presented on the example of the formation of a set of parameters necessary for assessing the personality, taking into account the specifics of the activity and the structure of the organization.
