Sustaining the National Health Insurance Scheme in South Africa: The Roles and Challenges of Community Health Workers

The provision of universal health coverage is acknowledged as a priority goal for healthcare systems globally. In South Africa, the National Health Insurance system has been endorsed as a funding model for the provision of universal health coverage for South Africans. Community Health Workers have contributed to better universal health coverage outcomes in many countries. A study in India revealed that coverage of health care practices is positively correlated with the knowledge level of Community Health Workers. In South Africa, there is a difference in the duration of training of Community Health Workers in different provinces, especially in Vhembe District.This study aimed to assess Community Health Workers’ knowledge regarding their roles and describe their challenges within the context of National Health Insurance.Qualitative design was used to collect data from 33 participants who formed five focus groups comprising six to eight members each. Ethical principles of research such as permission, informed consent, voluntary participation and anonymity were observed. Data was analysed using thematic data analysis technique guided by Tesch open coding method.The findings revealed that Community Health Workers lack adequate knowledge regarding the roles they are expected to play within Ward Based Outreach teams. Some of the challenges they face include transportation to clients’ homes and poor reception in households.A review of the South African Qualification Authority health promoter unit standards is recommended coupled with the mentorship of Community Health Workers by retired nurses to help them understand their roles better.
Dynamic performance tuning of Hadoop

Hadoop is an open source mapreduce framework used by a large number of organizations. Its performance is important in increasing the usefulness of large scale data processing applications. Map slot value (MSV) is one of the configuration parameters that influences the resource allocation and the performance of a Hadoop application. MSV determines the number of map tasks that can run concurrently on a node. In this work, we develop an approach to dynamically change MSV during the execution of an application. Our approach converges to the best MSV for all types of applications and it does so with low overhead. Without dynamic approach, determining the best MSV of an application requires a very tedious process of measuring the map completion time for all MSV settings. Our approach also adjusts MSV for applications that may not have a single best MSV throughout their execution. Compared to the peformance of an application when it is using the best MSV, performance of our dynamic approach is within 4.6% with cold start and improves by as much as 5% with warm start.
Building a global dictionary for semantic technologies

This paper proposes a novel method for ﬁnding linear mappings among word vectors for various languages. Compared to previous approaches, this method does not learn translation matrices between two speciﬁc languages, but between a given language and a shared, universal space. The system was trained in two different modes, ﬁrst between two languages, and after that applying three languages at the same time. In the ﬁrst case two different training data were applied; Dinu’s English-Italian benchmark data [1], and English-Italian translation pairs extracted from the PanLex database [2]. In the second case only the PanLex database was used. The system performs on English-Italian languages with the best setting signiﬁcantly better than the baseline system of Mikolov et al. [3], and it provides a comparable performance with the more sophisticated systems of Faruqui and Dyer [4] and Dinu et al. [1]. Exploiting the richness of the PanLex database, the proposed method makes it possible to learn linear mappings among an arbitrary number languages.
On the Cauchy problem for reaction-diffusion equations

The simplest model of the Cauchy problem considered in this paper is the following (*) u t = Δu + u p , x ∈ R n , t > 0, u ≥ 0, p > 1, u| t=0 = φ ∈ C B (R n ), φ ≥ 0, φ ¬= 0 It is well known that when 1 (n+2)/n, if φ is «small», (*) has a global classical solution decaying to zero as t → +∞, while if φ is «large», the local solution blows up in finite time. The main aim of this paper is to obtain optimal conditions on φ for global existence and to study the asymptotic behavior of those global solutions
Assessing the influence of CCAFS’ climate data and tools: findings from an Outcome Harvesting evaluation

The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) integrates climate change research across all CGIAR Research Centres and Research Programs. Some of CCAFS’ work since 2010 has involved the development of high quality, accessible and easy-to-use climate data and tools. With an increased focus on achieving development outcomes influenced by such data and tools, a study was carried out starting in 2016 to evaluate the development effectiveness of some of CCAFS’ climate products: the GCM Climate Portal, MarkSimGCM, and the Climate Analogues tool (Box 1). The study was designed to explore whether use of these three products has led to development outcomes, and if so, what type of changes have been observed and how exactly the products have contributed to such changes. Outcomes here are defined as behavioural changes in individuals, groups or institutions doing something differently with respect to climate-change-related knowledge, attitude, capacity, policy or practice.
Medicinal plant parts and practices used by communities around the Miombo woodlands of Urumwa, Tanzania

A study to document medicinal plants parts and practices in relation to sustainable use was performed in communities around the Miombo woodland of Urumwa in Tanzania. Data collection was based on semi-structured interviews and discussion with key stakeholders. G-tests were used to ascertain differences in medicinal plants practices between women and men. Roots were the commonly used parts for medicine followed by barks. In practice, boiling and grinding were the preferred methods for preparing remedies. Remedies are admistered orally in decoctions form with lack of standardized dosages. Medicinal plants are collected from the reserve using both root digging and bark stripping methods. Local communities need sensitization through trainings on various aspects of medicinal plants practices especially issues of sustainable harvesting methods, simple processing, domestication and the importance of standardized dosages so as to improve work performance, ensure resource sustainability and contribute to development of the primary health care system in Tanzania.
Middle Jurassic volcanism in a magmatic-rich passive margin linked to the Caudiel Fault Zone (Iberian Range, East of Spain): biostratigraphical dating

During the Early and Middle Jurassic, the Iberian Basin (East of Spain) recorded the transition from a generally magma-poor passive margin, which operated during the latest Triassic and most of Early Jurassic, to a magma-rich passive margin, developed from Pliensbachian to early Middle Jurassic. The mainly submarine pyroclastic volcanism, with minor lava flows, followed active NW and NE trending extensional fault zones. One of these zones of weakness, from which the volcanic deposits were expelled to the sea bottom, was the Caudiel Fault Zone. Two volcanic phases in relation to this weakness line over the Middle Jurassic times have been identified. The main phase occurred during the deposition of the El Pedregal Formation, and the other, less significant, is included between the Casinos and the El Pedregal formations. So far, the accurate age of these volcanisms, critical in the knowledge of the palaeogeographical and geodynamical evolution of the Iberian Basin, has remained uncertain. The ammonite content of the carbonate successions, with which these rocks are interbedded, allows precise biostratigraphical dating at the chronozone scale. For this purpose, 9 sections have been measured and 360 specimens of ammonites were collected and determined. The obtained data indicate that the Middle Jurassic volcanic deposits that are linked to the Caudiel Fault Zone and included into the El Pedregal Formation show a slight diachrony. They were deposited around the boundary between the Late Aalenian Concavum and the Early Bajocian Discites chronozones. However, in very restricted areas of the Caudiel Fault Zone, an older intra-Murchisonae volcanism was recorded.
Characterization of DAHP Synthase L183Q Mutation Comparison to Wild One by Prokaryotic Expression System

The prokaryotic expression system was employed in order to compare the catalytic properties of L183Q mutation and wild DAHP synthase enzyme. The gene of L183Q mutation and wild DAHP synthase enzyme was cloned and expressed by pET vector system and Eco.li BL21. The specific activity of the two recombinant enzyme was determinated. The result show that the relative activity of wild and L183Q mutation is 2.4u/mg and 3.6u/mg, respectively. But the optimal pH and temperature difference between wild and mutation DAHP synthase enzyme is not significant (p>0.05).
Extracting company names from text

A detailed description is given of an implemented algorithm that extracts company names automatically from financial news. Extracting company names from text is one problem; recognizing subsequent references to a company is another. The author addresses both problems in an implemented, well-tested module that operates as a detachable process from a set of natural language processing tools. She implements a good algorithm by combining heuristics, exception lists and extensive corpus analysis. The algorithm generates the most likely variations that those names may go by, for use in subsequent retrieval. Tested on over one million words of naturally occurring financial news, the system has extracted thousands of company names with over 95% accuracy (precision) compared to a human, and succeeded in extracting 25% more companies than were indexed by a human. <<ETX>>
High On/Off Ratio Memristive Switching of Manganite/Cuprate Bilayer by Interfacial Magnetoelectricity

Memristive switching serves as the basis for a new generation of electronic devices. Conventional memristors are two‐terminal devices in which the current is turned on and off by redistributing point defects, e.g., vacancies. Memristors based on alternative mechanisms have been explored, but achieving both high on/off ratio and low switching energy, as needed in applications, remains a challenge. This study reports memristive switching in La0.7Ca0. 3MnO3/PrBa2Cu3O7 bilayers with an on/off ratio greater than 103 and results of density functional theory calculations in terms of which it is concluded that the phenomenon is likely the result of a new type of interfacial magnetoelectricity. More specifically, this study shows that an external electric field induces subtle displacements of the interfacial Mn ions, which switches on/off an interfacial magnetic “dead layer”, resulting in memristive behavior for spin‐polarized electron transport across the bilayer. The interfacial nature of the switching entails low energy cost, about of a tenth of atto Joule for writing/erasing a “bit”. The results indicate new opportunities for manganite/cuprate systems and other transition metal oxide junctions in memristive applications.

The process of heat transfer and fluid flow in CFD problems

In many applications we need to use the CFD technology in order to model the problem and find exact solutions with less cost. In market can be found many special CFD software solutions where the user must programming according its problem and its special situations he wants to solve. In order to formulate the starting problem in a suitable form acceptable from the CFD package must follow a variety of steps which are no so clearly. Here, we try to present all these steps, and give the basic equations per step.
Encyclopedia of Fish Physiology : From Genome to Environment

Fish form an extremely diverse group of vertebrates. At a conservative estimate at least 40% of the world's vertebrates are fish. On the one hand they are united by their adaptations to an aquatic environment and on the other they show a variety of adaptations to differing environmental conditions - often to extremes of temperature, salinity, oxygen level and water chemistry. They exhibit an array of behavioural and reproductive systems. Interesting in their own right, this suite of adaptive physiologies provides many model systems for both comparative vertebrate and human physiologists. This four volume encyclopedia covers the diversity of fish physiology in over 300 articles and provides entry level information for students and summary overviews for researchers alike. Broadly organised into four themes, articles cover Functional, Thematic, and Phylogenetic Physiology, and Fish Genomics. Functional articles address the traditional aspects of fish physiology that are common to all areas of vertebrate physiology including: Reproduction, Respiration, Neural (Sensory, Central, Effector), Endocrinology, Renal, Cardiovascular, Acid-base Balance, Osmoregulation, Ionoregulation, Digestion, Metabolism, Locomotion, and so on. Thematic Physiology articles are carefully selected and fewer in number. They provide a level of integration that goes beyond the coverage in the Functional Physiology topics and include discussions of Toxicology, Air-breathing, Migrations, Temperature, Endothermy, etc. Phylogenetic Physiology articles bring together information that bridges the physiology of certain groupings of fishes where the knowledge base has a sufficient depth and breadth and include articles on Ancient Fishes, Tunas, Sharks, etc. Genomics articles describe the underlying genetic component of fish physiology and high light their suitability and use as model organisms for the study of disease, stress and physiological adaptations and reactions to external conditions.
AN OVERVIEW OF PRIVACY SCHEME IN CLOUD COMPUTING

Cloud computing provides a virtualized pool of computing resources. Cloud computing is categorized in three different broad service models: Software as a Service (SaaS); Platform as a Service (PaaS); Infrastructure as a Service (IaaS). An example is the accessing ofservices from remote databases through the use of Internet. This means users cannot physically or directly access data from the cloud server, without a client’s knowledge. Therefore, there is no need for users to know the exact location of the server; but there is a need for securing the data and information especially in public cloud computing. The aim of this study was to investigate the security challenges or vulnerabilities of cloud computing and propose a conceptual solution. In this regard, a systematic literature search was conducted. Descriptive statistics was used to analyse the data. The researcher found that there are a lot of research issues within the area of security in cloud computing. Furthermore, through this overview study the researcher found that most policies of cloud computing providers allow them to modify or delete data which is not used or that occupy a chunk of the storage space without consulting the clients. This is another security vulnerability issue which creates a research platform.
Radial Velocity Studies of Close Binary Stars. IV.

Radial velocity measurements and sine-curve fits to the orbital velocity variations are presented for the fourth set of 10 close binary systems: 44 Boo, FI Boo, V2150 Cyg, V899 Her, EX Leo, VZ Lib, SW Lyn, V2377 Oph, Anon Psc (GSC 8-324), and HT Vir. All systems are double-lined spectroscopic binaries, with only two of them not being contact systems (SW Lyn and GSC 8-324) and five (FI Boo, V2150 Cyg, V899 Her, EX Leo, and V2377 Oph) being the recent photometric discoveries of the Hipparcos project. Five of the binaries are triple-lined systems (44 Boo, V899 Her, VZ Lib, SW Lyn, and HT Vir). Three (or possibly four) companions in the triple-lined systems show radial velocity changes during the span of our observations, suggesting that these are in fact quadruple systems. Several of the studied systems are prime candidates for combined light and radial velocity synthesis solutions.
Motion Superpixels for Temporal Video Classification

Superpixels are a representation of still images as pixel grids because of their more meaningful information compared with atomic pixels. However, their usefulness for video classification has been given little attention. In this paper, rather than using spatial RGB values as low-level features, we use optical flows mapped into hue-saturation-value (HSV) space to capture rich motion features over time. We introduce motion superpixels, which are superpixels generated from flow fields. After mapping flow fields into HSV space, independent superpixels are formed by iteration of seeded regions. Every grid of a motion superpixel is tracked over time using nearest neighbors in the histogram of flow (HOF) for consecutive flow fields. To define the temporal representation, the evolution of three features within the superpixel region, namely the HOF, HOG, and the center of superpixel mass are used as descriptors. The bag of features algorithm is used to quantify final features, and generalized histogram-kernel support vector machines are used as learning algorithms. We evaluate the proposed superpixel tracking on first-person videos and action sports videos.
Grid-based modeling in “Wissensnetz Energiemeteorologie”

The research project WISENT (Wissensnetz Energiemeteorologie) combines efforts of computer and atmospheric scientists to optimize the cooperation of scientific organizations in the field of energy meteorology. One of the goals is to provide easy access to distributed computing resources of the German Grid (D-Grid) for running numerical weather prediction models. Based on experience with our introductory implementation of the Weather Research and Forecasting (WRF) model in the computing cluster at OFFIS, the applicability of Grid computing approaches in this context along with their benefits and technical challenges in the areas of usability, multiuser operation, software configuration and data management are examined. Results of verification tests of different WRF configurations are presented. Daily WRF runs for March, April & May (MAM) 2007 period have been performed in an “off-the-shelf” configuration with a forecast horizon of up to 48 hours, based on the NCEP analysis cycle of 00 UTC. The initial results showed that, meteorologically, the WRF forecasts did not perform as well as expected. Our future work will focus on tuning WRF to improve its prediction quality and on overcoming the technical challenges to establish numerical weather prediction as one of the scientific applications in D-Grid.
ENTREPRENEURSHIP INTENTION AMONG OPEN UNIVERSITY MALAYSIA (OUM) LEARNERS

Entrepreneurship plays an important role in contributing to the nation economic growth and creates job opportunities to the country. Ministry of education in Malaysia has even included entrepreneurship as part of the syllabus in higher learning education in order to foster local entrepreneurs among learners. Entrepreneurship education has become an important curriculum in the higher education institutions in Malaysia (Ismail et al., 2009) and a core subject for most programmes in Malaysia. A subject by itself, entrepreneurship, has been embedded into the programmes and entrepreneurship is offered as a programme even in several public and private higher education providers, Open University Malaysia (OUM) too has a course under the university compulsory category in the academic for all offered programme in the curriculum called Entrepreneurship with code OUMM2103. This course has become popular and receptive by the undergraduates in OUM. Entrepreneurship education has now become an essential component to cultivate the potential entrepreneurs in the higher learning institutions. According to Ismail et al., (2009), entrepreneurship education is the most effective way to promote the transition of graduates toward the selfemployment. This study aims to investigate the factors which will influence the entrepreneurship intention among OUM learners using structural equation modeling (SEM). The results of the finding shows there are a significant influence of attitude and perceive behavioural control to entrepreneurship intention. However, subjective norms do not significantly influence the entrepreneurship intention among OUM learners. The overall findings of this research have limitations in terms to generalise the results. The results of this study will be able to provide an insight to the educators to help all learners to develop their abilities and skills to produce a higher rate of entrepreneurs in the nation.

Gender Discrimination and Growth in Major Economies in Asia

Economic growth, its determination and distribution have been the main objectives of normative and positive market economics over the years. Less focused is the effect of gender discrimination (or a lack of it) on growth from both the market and non-market perspectives in an economy, developed and developing. The paper implements and improves on a recent model of growth incorporating gender discrimination [see Rosen (1982) and Esteve-Volart (2004)] to empirically investigate the possible effect of this discrimination on growth in recent years in major countries in the Asian region. Some policy recommendations are also briefly discussed.
