Healthcare Big Data

Big data has unlocked a new opening in healthcare. Thanks to the considerable benefits and opportunities, it has attracted the momentous attention of all the stakeholders in the healthcare industry. This chapter aims to provide an overall but thorough understanding of healthcare big data. The chapter covers the 10 ‘V's of healthcare big data as well as different healthcare data analytics including predictive and prescriptive analytics. The obvious advantages of implementing big data technologies in healthcare are meticulously described. The application areas and a good number of practical use cases are also discussed. Handling big data always remains a big challenge. The chapter identifies all the possible challenges in realizing the benefits of healthcare big data. The chapter also presents a brief survey of the tools and platforms, architectures, and commercial infrastructures for healthcare big data.

Using Social Media to Advocate LGBT Rights in Black Africa

The prevalence of draconian homophobic laws in Cameroon and Nigeria has systematically stultified sympathy for the LGBT communities and made pro-gay street activism a risky venture in these two countries. In view of this, a good number of gay rights activists have resorted to the social media as a suitable platform for a less risky advocacy. Using the social media has afforded them the opportunity to explore interactive, post-modern, and personified approaches to sensitizing and mobilizing their readership in favour of gay proselytism in Cameroon, Nigeria, and some other parts of Africa. Based on a content analysis of 200 blog posts and web/facebook pages generated by Cameroonian and Nigerian gay activists, this chapter measures the extent to which gay activists adopt a national/local perspective versus the level to which they adopt an international perspective in their online advocacy. The chapter equally examines the degree to which these citizen journalist/activists construct their advocacy discourse from the prism of a cultural war between the West and Africa.

NUMBER SENSE DALAM MEMECAHKAN MASALAH MATEMATIKA PADA MAHASISWA IKIP PGRI PONTIANAK

Number sense is a person towards numbers, number sense is needed for students in the process of learning mathematics. Students with good number sense will be able to use their knowledge of numbers in solving mathematical problems. Therefore, it is necessary to do about how students use their number sense skills in mathematical problem situations. This study aims to determine how the number sense of students in solving mathematical problems. This type of research is qualitative research. The method used is a descriptive method in the form of case study research. The subjects in this study were IKIP PGRI Pontianak students who came from the mathematics education study program which collected 8 people. The instruments used in this study were test questions and interviews. From the results of data analysis and subject representation in displaying number sense in each C1-C5 component, the researcher concluded that all subjects had good number sense, seen from all who had number sense with a percentage of more than 60%.

Morente-Lorca, Lorca-Morente

In this paper we will focus on Morente-Lorca, the explicit recording that Enrique dedicated in 1998 to Fuente Vaqueros on the centenary of his birth. Produced by La Barbería del Sur under the artistic direction of the cantaor and arranged in two sections by Giorgi Petkov and Giorgi Krassimirov, it was structured in 14 tracks. In a good number of them, Morente started from different poems and fragments of Lorca dramas (So after five years, Doña Rosita la soltera, Yerma, Poeta en Nueva York, Poema del cante jondo and Diwán del Tamarit) that were put to music by Juan Manuel Cañizares, Juan Carlos Romero and by himself (he also took letters from San Juan de la Cruz and Francisco García Lorca). Among them, “Campanas por el poeta” stands out, a song recorded live by the engineer José Ángel Ruiz in the Plaza de la Catedral in Barcelona at the 1998 Mercè Festival. In addition to the live performance, they also added the sound of the bells of the city of Granada collected from the Plaza de San Nicolás del Albaicín at 5 in the morning. They also picked up other echoes of the dawn atmosphere of the city of the Alhambra. En este artículo nos centraremos en Morente-Lorca, la explícita grabación que el del Albaicín dedicó en 1998 al de Fuente Vaqueros en el centenario de su nacimiento. Producida por La Barbería del Sur bajo la dirección artística del cantaor y con arreglos en dos secciones de Giorgi Petkov y Giorgi Krassimirov, se estructuró en catorce cortes. En varios de ellos, Enrique partió de distintos poemas y fragmentos de dramas lorquianos (Así que pasen cinco años, Doña Rosita la soltera, Yerma, Poeta en Nueva York, Poema del cante jondo y Diwán del Tamarit) que fueron puestos en música por Juan Manuel Cañizares, Juan Carlos Romero y por él mismo (también tomó letras de san Juan de la Cruz y Francisco García Lorca).Entre ellos, sobresale “Campanas por el poeta”, tema grabado en vivo por el ingeniero José Ángel Ruiz en la plaza de la Catedral de Barcelona en las Fiestas de la Mercè de 1998. Además de la interpretación en vivo, también añadieron el sonido de las campanas de la ciudad de Granada recogido desde la plaza de san Nicolás del Albaicín a las cinco de la mañana. Del mismo modo, tomaron otros ecos del ambiente del amanecer de la ciudad de la Alhambra.

The Impact of Edge Correlations in Random Networks

Random graphs are frequently used models of real-life random networks. The classical Erdös–Rényi random graph model is very well explored and has numerous nontrivial properties. In particular, a good number of important graph parameters that are hard to compute in the deterministic case often become much easier in random graphs. However, a fundamental restriction in the Erdös–Rényi random graph is that the edges are required to be probabilistically independent. This is a severe restriction, which does not hold in most real-life networks. We consider more general random graphs in which the edges may be dependent. Specifically, two models are analyzed. The first one is called a p-robust random graph. It is defined by the requirement that each edge exist with probability at least p, no matter how we condition on the presence/absence of other edges. It is significantly more general than assuming independent edges existing with probability p, as exemplified via several special cases. The second model considers the case when the edges are positively correlated, which means that the edge probability is at least p for each edge, no matter how we condition on the presence of other edges (but absence is not considered). We prove some interesting, nontrivial properties about both models.

The Necessity for Revisiting Direct Corporate Human Rights Obligations in the Current Business and Human Rights Treaty Process

The international community has awoken to the reality that transnational corporations (TNCs) do not only control more resources than a good number of states. They wield enormous influence in the corporate world which greatly impacts on local cultures and initiatives. Many of these TNCs, who operate in developing states, engage in activities which frequently result in human rights abuses. Several states rely on the resources extracted by these large corporations as the main stay of their economies. Consequently, they lack the economic capacity and political will to effectively regulate the activities of the TNCs, leaving these entities to perpetrate human rights abuses in the local communities with impunity. Although the Human Rights Council, through the Inter-governmental working group on Business and Human Rights, has begun a treaty process on business and human rights to address these issues, the work of the IGWG, so far, has not adequately responded the root cause of the corporate impunity, which is their unwillingness and inability to hold corporate entities accountable for their harmful activities. Thus, this paper proposes that the issue of direct human rights obligations on corporate entities should be revisited in order to ensure that corporate entities do not escape accountability for human rights harm resulting from their activities.

The chemistry of melting oxynitride phosphate glasses

Oxide glasses are the most commonly studied non-crystalline materials in Science and Technology, though compositions where part of the oxygen is replaced by other anions, e.g. fluoride, sulfide or nitride, have given rise to a good number of works and several key applications, from optics to ionic conductors. Oxynitride silicate or phosphate glasses stand out among all others because of their higher chemical and mechanical stability and their research continues particularly focused onto the development of solid electrolytes. In phosphate glasses, the easiest way of introducing nitrogen is by the remelting of the parent glass under a flow of ammonia, a method that allows the homogeneous nitridation of the bulk glass and which is governed by diffusion through the liquid-gas reaction between NH3 and the PO4 chemical groupings. After nitridation, two new structural units appear, the PO3N and PO2N2 ones, where nitrogen atoms can be bonded to either two or three neighboring phosphorus, thus increasing the bonding density of the glass network and resulting in a quantitative improvement of their properties. This short review will gather all important aspects of the synthesis of oxynitride phosphate glasses with emphasis on the influence of chemical composition and structure.

The Slow Fall of Babel

This is the story of the transformation of the ways in which the increasingly Christianized elites of the late antique Mediterranean experienced and conceptualized linguistic differences. The metaphor of Babel stands for the magnificent edifice of classical culture that was about to reach the sky, but remained self-sufficient and self-contained in its virtual monolingualism – the paradigm within which even Latin was occasionally considered just a dialect of Greek. The gradual erosion of this vision is the slow fall of Babel that took place in the hearts and minds of a good number of early Christian writers and intellectuals who represented various languages and literary traditions. This step-by-step process included the discovery and internalization of the existence of multiple other languages in the world, as well as subsequent attempts to incorporate their speakers meaningfully into the holistic and distinctly Christian picture of the universe.

An account of fog over Chennai

Climatologically (based on 1951-1980) the annual fog frequency of Chennai airport is 4.3 days. But, the operational aviation meteorological forecasters often experienced more number of foggy days during the past decade. Hence the fog frequency has been critically analysed based on current weather observations made by aerodrome meteorological office, Chennai during 1981-2002 (barring 1984 for which data is not readily available). It has been found that the annual frequency based on the present study has shot up to 21.5 days. The most favourable period for fog over Chennai airport has been identified as January followed by February and March. The formation of fog has been mostly observed during 0000-0200 UTC although in good number of cases it was during 2200-2400 UTC. The most common duration of fog is 60-120 minutes albeit duration as high as 540-570 minutes are also probable. The low level (surface) nocturnal inversion frequency has alarmingly increased during 1990s and the inversion is almost a day-to-day phenomenon during 2000s. Rapid urbanisation, vehicular traffic and industrial growth could be the cause for the increased atmospheric pollution which has increased the nocturnal stability conditions as well the fog frequency. Visibility as low as zero had been recorded on a number of cases and their causes have been analysed. Neutral or absolutely unstable stratification at 1200 UTC coupled with high relative humidity and high concentration of pollution cause the fog to form from 2200 UTC onwards and the nocturnal surface inversion / isotherm at 0000 UTC maintains the fog. Though the low level inversion maintains the fog once it is formed already, inversion alone is not a sufficient condition for the formation of fog.

Proximate composition and bioaccumulation of heavy metals in edible Achatina spp in some rural agro-settlements, south-east Nigeria

Background Animals that live and feed on the soil and its constituents and products naturally absorb heavy metals and pass to other organisms linked in the food chains. The present study was designed to examine bioaccumulation of heavy metals levels and proximate composition quality in edible Achatina spp sampled in agro-rural settlements, south-east Nigeria. Results The proximate composition recorded the presence of moisture, protein, crude fibre, fat and oil, ash, carbohydrates, nitrogen and calcium, which were similar across selected Achatina spp except for calcium, which was significantly higher in A. achatina. The bioaccumulation factors of heavy metal contents in snails were generally low (below recommended tolerable limits according to WHO standard). Conclusion The good number of nutrients recorded in proximate composition makes the Achatina spp an alternative to domestically farmed animals. Achatina achatina contained most calcium level compared with Achatina fulica and Achatina marginate. The bioaccumulation factors of heavy metal contents in snails were generally low (below recommended tolerable limits according to WHO standard). Land snails in our study areas were safe for consumption.
