Immanence, Abjection and Transcendence through Satī/Śakti in Prabha Khaitan’s Autobiography "Anyā se ananyā"
Authors: Consolaro Alessandra
Published: January 2019

This article aims to explore embodiment as articulated in Prabha Khaitan’s autobiography Anyā se ananyā, inscribing it in a philosophical journey that refuses the dichotomy between Western and Indian thought. Best known as the writer who introduced French feminist existentialism to Hindi-speaking readers through her translation of Simone de Beauvoir’s The Second Sex, Prabha Khaitan is positioned as a Marwari woman, intellectual, successful businesswoman, poet, novelist, and feminist, which makes her a cosmopolitan figure. In this article I use three analytical tools: the existentialist concepts of ‘immanence’ and ‘transcendence’—as differently proposed by Jean-Paul Sartre and Simone de Beauvoir; Julia Kristeva’s definition of ‘abjection’—what does not ‘respect borders, positions, rules’ and ‘disturbs identity, system, order;’ and the satī/śakti notion—both as a venerated (tantric) ritual which gains its sanction from the scriptures, and as a practice written into the history of the Rajputs, crucial to the cultural politics of Calcutta Marwaris, who have been among the most vehement defenders of the satī worship in recent decades.

Surgical Management of Giant Congenital Hairy Nevi Without Skin Graft or Other Methods of Closure
Authors: Sukasah Chaula L , Supit Laureen
Published: January 2019

Congenital hairy nevus refers to pigmented skin lesion presents at birth. Giant hairy nevus (GHN) is disfiguring and carries a great emotional distress on the patient and family. It also imposes a higher risk for developing malignant melanomas and other tumors. The management of GHN depends on the lesions’ size, location and its propensity to become malignant. When surgery is indicated, the simplest approach is a staged serial excisions. The longstanding challenge is in reconstructing the raw surface defect, especially if large. A case of congenital GHN on the trunk, abdomen and bilateral upper thighs was presented and the data was taken from the medical record from the Plastic and Reconstructive Surgery Division of Cipto Mangunkusumo Hospital. Patient was managed surgically with a technique similar to dermabrasion, by scalpel instead of dermabrator, to peel the skin in partial-thickness. In each surgery, not more than 10% of the total body surface area was excised and left to heal secondarily. Compression was used to reduce risk of hypertrophic scar formation. Subsequent operation was ideally 3 weeks apart, to allow for the excised surface to epithelialize and the body to return to homeostasis. Although visible, the patient’s family prefer the resulting scar than the initial lesion, because the skin is lighter, hairless, and less frightening. At two-years follow up, the patient still refuse further operation due to economical and social issues.

Authors: A. Teuku , P. Nandita Melati , Sudjatmiko Gentur , S. Asrofi , D. Ishandono
Published: January 2019

Background: Split thickness skin graft (STSG) is one of the modalities used to close a defect. The donor site can be healed secondarily with tulle grass and moist gauze after 14 days and with transparent dressing will take about 10-13 days. Recently the wound healing by using honey application has been used. Whether or not using honey application with transparent dressing will hasten the epithelialization rate of the STSG donor site is now in question. Method: This research is an open, non-randomized clinical trial with a parallel design and intervention using honey application with transparent dressing. A total of 19 patients (7 female and 8 male) were included in this study. The reapplication of honey was done every two days. The patients was followed up every day, with clinical photograph taken and complaints such as pain, odor and infection noted. Results: The mean epithelialization rate of the donor site treated with honey and transparent dressing was 9,74 (+0,24) days compared to 10,79 (+1,23) days in the transparent-dressing-only group (p=0,00). Conclusion: The application of honey with transparent dressing to cover for STSG donor site led to a faster epithelialization rate, less odor and less pain. Commercial honey was used, and readily available.

Authors: Mineev V. , Vasilyeva T. , Kuzmina A. , Lalaeva T.
Published: January 2019

The aim is analysis of possible influence of pro- and antiinflammatory cytokine having key pathogenetic value on the glomerular filtration rate in bronchial asthma (BA). Material and methods. We examined 51 patients with BA. Glomerular filtration rate (eGFR) by CKD-EPI was estimated. The content of IL-4, IL-6, IL-10 and TNF-α in plasma were determined using enzyme immunoassay method (ELISA). Factor analysis using the program SPSS for Windows, version 21.0 was performed. Results. In allergic BA (ABA) factor analysis identified 3 factors that characterize the role of IL-6 in the development of both the key characteristics of BA (bronchial obstruction), and key features of CKD (eGFR), as well as the failure of the system of regulation of proinflammatory/anti-inflammatory cytokines balance. In nonallergic BA (NABA) factor analysis identified 4 factors that characterize in particular the influence of the TNF-α expression on the severity of the disease and the value of eGFR. The more severe BA the greater the decrease in eGFR. Conclusion. Possible pathogenetic relationship between the expression of key proinflammatory cytokines (IL-6, TNF-α) and glomerular filtration rate in BA is discussed. In ABA the IL-6 expression has probably common pathogenetic value when forming bronchial obstruction and CKD, on the other hand in NABA the TNF-α overexpression has likely common pathogenetic value when forming bronchial obstruction (possibly due to influence on bronchial remodeling) and CKD.

Published: January 2019

Kebocoran tangki bahan bakar minyak untuk kereta api di Stasiun Tugu Yogyakarta pada tahun 1997 menyebabkan pencemaran airtanah pada sumur-sumur penduduk. Bahan bakar minyak (hidrokarbon) tergolong LNAPLs (Light Non Aqueous Phase Liquids), sukar larut dalam air. Penyebaran kontaminan (plume) pada airtanah dipengaruhi oleh biodegradasi. Penelitian terdahulu oleh Setyaningsih (2010) menyebutkan bahwa kecepatan aliran pada daerah penelitian adalah 1,5 km per tahun dalam kurun waktu 5 tahun, plume sudah mengalir jauh dari daerah penelitian. Berdasarkan informasi tersebut, sangat perlu diketahui arah pergerakan aliran airtanah dari 24 sumur observasi. Daerah penelitian merupakan bagian atas dari Sistem Akuifer Merapi (SAM) dengan penyusun endapan pasir dan endapan pasir krikilan, dengan aliran airtanah yang tidak seragam. Secara umum, aliran airtanah di daerah penelitian berarah utara-selatan. Di bagian selatan, aliran terpisah ke arah timur dan barat karena keberadaan sungai yang juga membatasi daerah penelitian. Hasil pengukuran dan analisa sampel airtanah menunjukkan 13 sumur observasi diindikasikan tercemar oleh hidrokarbon dengan plume sepanjang 325 m bergerak dari barat laut ke tenggara. Simulasi penyebaran pencemar dan konsentrasi hidrokarbon terlarut dibuat pemodelan menggunakan BIOPLUME III. Nilai kandungan hidrokarbon yang dipakai diambil dari data sumur, yaitu 1 mg/L hingga 50 mg/L. Pergerakan plume di daerah penelitian mengikuti arah aliran airtanah dan diestimasi mengalami penurunan konsentrasi kemudian hilang setelah 54 tahun. Nilai konsentrasi berkurang dari 50 mg/L menjadi 1,63 mg/L dengan rata-rata penurunan konsentrasi sebesar 7,95 mg/L selama 10 tahun.

Published: January 2019

The syntactic and semantic properties of theinto-causativeconstruction, involving the pattern ‘V NP into V-ing’, has been studied in some detail, but its historical development has received less attention. This paper looks at the historical shifts in the construction with much more representative and robust corpora than have been used for previous studies. Based on nearly 11,440 tokens from more than 950 million words of text, the paper considers several important changes in the lexical, syntactic, and semantic properties of the construction. The study also establishes the value of large, diverse historical corpora and their role in researching syntactic and semantic change.
Metamaterials and chiral sensing: a review of fundamentals and applications
Authors: Yoo SeokJae , Park Q-Han
Published: January 2019

Chirality, a property of broken mirror symmetry, prevails in nature. Chiral molecules show different biochemical behaviors to their mirror molecules. For left or right circularly polarized lights, the fundamental chiral states of electromagnetic fields interact differently with chiral matter, and this effect has been used as a powerful tool for the detection of chiral molecules. This optical sensing, also termed chiral sensing, is not only easy to implement but also non-invasive to the analytes. However, the measurements made by the optical sensing of chiral molecules are challenging, as chiroptical signals are extremely weak. Recent years have seen active research efforts into metamaterial and plasmonic platforms for manipulating local fields to enhance chiroptical signals. This metamaterial approach offers new possibilities of chiral sensing with high sensitivity. Here, we review the recent advances in chiral sensing using metamaterial and plasmonic platforms. In addition, we explain the underlying principles behind the enhancement of chiroptical signals and highlight practically efficient chiral sensing platforms. We also provide perspectives that shed light on design considerations for chiral sensing metamaterials and discuss the possibility of other types of chiral sensing based on resonant metamaterials.
Preparation and properties of plasmonic-excitonic nanoparticle assemblies
Authors: Szychowski Brian , Pelton Matthew , Daniel Marie-Christine
Published: January 2019

The assembly of inorganic nanoparticles often leads to collective properties that are different from the combined properties of the individual components. In particular, coupling plasmonic and excitonic nanoparticles has been shown to modify their optical properties, including absorption, emission, and scattering. Because of this, these coupled assemblies have potential applications in a wide range of areas, including sensing, light harvesting, and photocatalysis. More recently, unique properties, including Fano interference and Rabi splitting, have been observed by increasing the coupling strength. However, the behavior of coupled nanoparticles is highly dependent on the exact organization of the components, including the number of particles coupled, the distance separating them, and their spatial orientation. This is especially true in the case of strongly coupled particles. Because of this, it is important to achieve synthetic techniques that not only can link particles together but also offer good control over how the particles are connected. In this review, assemblies of plasmonic and excitonic nanoparticles are reviewed, including the various methods that have been used for their construction, the properties that these systems have been predicted to possess as well as the ones that have been observed, and their current applications along with current challenges in the field and potential future applications.

Authors: Guirao Juan Luis García , Siddiqui Muhammad Kamran , Hussain Asif
Published: January 2019

Networks play an important role in electrical and electronic engineering. It depends on what area of electrical and electronic engineering, for example there is a lot more abstract mathematics in communication theory and signal processing and networking etc. Networks involve nodes communicating with each other. Graph theory has found a considerable use in this area of research. A topological index is a real number associated with chemical constitution purporting for correlation of chemical networks with various physical properties, chemical reactivity. The concept of hyper Zagreb index, first multiple Zagreb index, second multiple Zagreb index and Zagreb polynomials was established in chemical graph theory based on vertex degrees. In this paper, we extend this study to interconnection networks and derive analytical closed results of hyper Zagreb index, first multiple Zagreb index, second multiple Zagreb index, Zagreb polynomials and redefined Zagreb indices for block shift network (BSN− 1) and (BSN− 2), hierarchical hypercube (HHC− 1) and (HHC− 2).

The paper presents research focused on the efficiency improvement of inorganic flexible thin-film solar cells, using energy converting layers. The light capture enhancement was achieved through the introduction of layers based on rare-earth elements, as top coatings on the amorphous silicon photovoltaic structures. Such luminescent layers are converting high-energy photons into low-energy ones, which are more efficient in photovoltaic conversion of the investigated solar cells. Towards this goal, powders consisting rare-earth elements were applied as active particles in polymer layer. For practical experiments, the screen-printing method, as a cheap, reliable and industrially-ready technology was used for layers deposition. For the experiments two compositions were selected: Sr4Al14O25: Eu,Dy (BGL-300M) and SrAl2O4: Eu,Dy (G-300M). These materials are characterized by excellent thermal and optical stability and interesting luminescent properties (they absorb ultraviolet and emit in the visible range). For the verification of investigated materials and methods, various compositions of powders and proportions were tested and analyzed.
Study on the response characteristics of oil wells after deep profile control in low permeability fractured reservoirs
Authors: Lin Lijun , Lin Wei
Published: January 2019

The rhombus inverted nine-spot well pattern is often adopted in low permeability oilfield development, which has the advantage of high oil production rate and flexible adjustment. Due to the strong heterogeneity of the low permeability reservoirs, the oil wells along the fracture direction are heavily water-flooded and the water cut rises quickly, and the oil wells on both sides of fractures have no response to water injection. Hence, deep profile control is an effective way to solve this kind of plane contradiction, and is widely applied in the low permeability oilfield development. However, because of the asymmetry of the rhombus inverted nine-spot well pattern and the heterogeneity of the low permeability reservoirs, there are differences in the response characteristics of oil wells at different locations after deep profile control. In this paper, combined with physical experiments and numerical simulations, we analyzed oil increment, the distribution of streamlines and slugs of wells at different locations before and after deep profile control, and evaluated the response characteristics of oil wells of rhombus inverted nine-spot well pattern after deep profile control in low permeability fractured reservoirs. It is concluded that the effect of increasing oil production of the side wells is better than that of the angle wells after deep profile control, and the response sequence is side well, angle well in short axis, and angle well in long axis, which is also verified by the practical results of deep profile control in Daqing Oilfield.
An attempt to geometrize electromagnetism
Authors: Huang XiuLin , Xu Yan , Liu ChengZhi
Published: January 2019

This study investigates the curved worldline of a charged particle accelerated by an electromagnetic field in flat spacetime. A new metric, which dependes on the charge-to-mass ratio and electromagnetic potential, is proposed to describe the curve characteristic of the world-line. The main result of this paper is that an equivalent equation of the Lorentz equation of motion is put forward based on a 4-dimensional Riemannian manifold defined by the metric. Using the Ricci rotation coefficients, the equivalent equation is self-consistently constructed. Additionally, the Lorentz equation of motion in the non-inertial reference frames is studied with the local Lorentz covariance of the equivalent equation. The model attempts to geometrize classical electromagnetism in the absence of the other interactions, and it is conducive to the establishment of the unified theory between electromagnetism and gravitation.

Published: January 2019

Latent heat storage represents a promising technique to achieve net zero energy buildings. This work investigates the behaviour of phase change material (PCM) inside a rectangular enclosure, which represents the geometry of a latent heat storage system. The left side of the unit is exposed to a constant temperature (Th), while the other three walls are exposed to convection heat transfer boundary condition [h= 5, 10, and 15 W/(m2 K)] and different ambient temperatures (T∞ = 297◦ and 307◦K). The ambient temperatures were selected to be at/above the melting temperature of the studied PCM (coconut oil). To study the melting process of the PCM, the continuity, Navier-Stokes and energy equation were used. The Navier-Stokes equations were modified using the Carman-Kozeny relation. The finite element method was utilized to produce numerical results. The results are presented in terms of flow and thermal fields, Nusselt number (Nu), and the melt fraction (MF) of the PCM. The results show that, when T∞ = Tm, the melting rate of the PCM slows down with increasing the convection heat transfer coefficient. While the melting rate accelerates with increasing the convection heat transfer coefficient when T∞ > Tm.
Nuclear forensics on uranium fuel pellets

Published: January 2019

Nuclear forensic analysis of uranium oxide fuel pellets and the respective data interpretation have proven to be important elements of the investigative process when such material is found out of regulatory control. Uranium oxide fuel pellets are produced at industrial scale and have to meet tight technical specifications. Variations in the production process of different manufacturers or fuel fabrication facilities offer an additional source of information. The compilation of such information in a nuclear materials database has proven to be a highly valuable resource. In consequence, measureable material properties (referred to as “signatures”) such as the isotopic composition, the physical dimensions, the chemical impurities, the products of the radioactive decay of uranium and the microstructure allow establishing the processing history of the material. To this end, dedicated analytical methods have to be developed and suitable methods for data evaluation and interpretation need to be utilised. The successful application of these nuclear forensic tools is illustrated with two case studies on real incidents of illicit nuclear trafficking of uranium oxide fuel pellets.
Separation of neptunium from actinides by monoamides: a solvent extraction study
Authors: Mahanty Bholanath , Kanekar Avinash S. , Ansari Seraj A. , Bhattacharyya Arunasis , Mohapatra Prasanta K.
Published: January 2019

Separation of neptunium from a mixture of actinides viz. uranium, neptunium and plutonium was evaluated using two monoamides, viz. N,N,-dihexyl octanamide (DHOA) and N,N,-dihexyl decanamide (DHDA). The extraction of actinides with these ligands followed the order: U(VI)>Np(IV)>>Pu(III). Poor extraction of Pu(III) with both the amides (DHOA and DHDA) was exploited for the mutual separation of U, Pu and Np. At 3 M HNO3, DHDA was a better extractant for all the three metal ions while Pu(III) extraction was one order magnitude lower with DHOA as compared to that seen with DHDA. Consequently, better separation factor of U(VI)/Np(IV) over Pu(III) was obtained with DHOA. In the actinide mixed solution, Pu was reduced to its +3 state followed by selective extraction of U(VI) and Np(IV). Subsequently, the mutual separation of U(VI) and Np(IV) was carried out by selective complexation and stripping of Np(IV) by acetohydroxamic acid (AHA) at 2 M HNO3, where U(VI) remained in the organic phase. The purity of the separated actinides was confirmed by alpha spectrometry. A separation scheme for the separation of Np from radioactive waste/high level waste has been proposed.

Evaluation of Plasma D-Dimer Concentration Among Normal and Complicated Pregnancies, Saudi Arabia
Authors: Zaini Rana , Al-Rehaili Amani , Kufia Rahma
Published: January 2019

Objectives: The purpose of the current work is to evaluate D-dimer plasma level among both normal and complicated pregnancies such as gestational diabetes (GD) and hypertension (GH) among Saudi females. It is also focused on exhibiting any possible factors that could also play a role in rising D-dimer levels besides the age of the pregnant woman and the period of gestation. Materials and Methods: A semi-quantitative latex agglutination assay was performed in the blood sample of healthy non-pregnant, pregnant and pregnant females with GD and GH. Results: The results exhibited that 92% of pregnancies with GH and 90% of multiple pregnancies had high D-dimer levels. The analysis of the effect of age of pregnant women on D-dimer concentrations presented that 100% of pregnant women with GD, GH or multiple pregnancies aged above 40, had high levels of D-dimer. The results of the relationship between gestational age of pregnancies and D-dimer showed that by reaching the third trimester, about 66.6% of women who had multiple pregnancies had D-dimer concentration above 2000 ng/mL. Interestingly, all the pregnant females with GH had D-dimer concentrations above 2000 ng/mL. Conclusions: This study postulated that the concentrations of D-dimer significantly increase during pregnancy associated with common complications such as GD and GH. It is the first study to demonstrate the possible risk factors during pregnancy, which include age, number of pregnancies, gestational age and pregnancies with GD and GH, especially among Saudi Arabian women.
Fitna
Authors: Mohamed Mohamed A.
Published: January 2019

Para expresar el concepto coránico de la fitna, este artículo se divide en tres partes. En la primera parte, se discuten la etimología, los significados y el uso del término fitna en el Qurʾān. Se argumenta que, aunque la palabra fitna indique decepción, seducción, anarquía y caos, al mismo tiempo se considera normativa, como el estado natural del mundo. La esencia de la fitna es una amalgama de verdad y mentira, la cual hace que los signos se vuelvan seductores y que se elimine el concepto de la verdad del campo de la razón. El significado no es ni verdadero ni falso, no está ni ausente ni presente: es incompleto, pues opera desde la esfera del ghayb, o la realidad invisible. En la segunda parte, se explora la fitna como concepto sociológico analítico, situándolo dentro de la teoría sociológica occidental. Se contrasta la fitna con conceptos relacionados en la obra de Sigmund Freud, Georges Bataille, Jean Baudrillard y Timothy Bewes. A través de una exploración del pensamiento de Ibn Taymiyya (1263-1328 CE) en su tratado sobre la verdad y la metáfora, y comparándolo con el de Bernard McGinn, se argumenta que, al articular el sentido y la verdad, el concepto de la fitna evita tanto la síntesis dialéctica como el dualismo cósmico, proponiendo en cambio una superposición parcial entre el ẓāhir y el ghayb, o los mundos visibles e invisibles. En la tercera parte, se estudian dos aspectos aplicados de la fitna: en el razonamiento legal y en la teología del apocalipsis. Se explica cómo una cosmovisión de la fitna incluye una noción formal de la verdad que es legal en vez de óntica y objetiva, y anclada en ghālib al-ẓann, o la probabilidad predominante. Finalmente, se conecta el caos apocalíptico al incremento en la superposición entre el ghayb y el ẓāhir, lo cual llega a abarcar hasta su posible identificación, pero esto último solamente llega con el fin de la fitna y el fin del mundo.
Perspectivas sobre Islam y el cuerpo
Authors: Harwell Katherine
Published: January 2019

Los ritos y jurisprudencia islámicos, los cuales regulan la gestión del cuerpo, distinguen el Islam de otras tradiciones religiosas y son entonces, al menos parcialmente, componentes constitutivos de la identidad musulmana. A pesar de la centralidad evidente del cuerpo en la formación de la subjetividad e identidad en el contexto islámico, existen disputas sobre cómo mejor llevar a cabo la práctica ritual. Este grupo de ensayos sobre el cuerpo tiene como fin describir y explicar algunos de estos espacios en disputa, además del papel que la pureza ritual y la disciplina juegan en el entrenamiento del cuerpo para poder realizar los ritos de manera efectiva. Busca además trazar los orígenes históricos de algunos de estos ritos, especialmente los que tienen como modelo el cuerpo del Profeta Mahoma y su ejemplo personal, y examina las distintas formas en las cuales su legado se interpreta teológica y legalmente en la comunidad musulmana.

Authors: Arias Echeverri Juan Pablo , Ortega Isabel Cristina , Peñuela Mariana , Arias Mario
Published: January 2019

Thevetia peruviana is an ornamental plant considered source of biologically compounds with cardiac and antimicrobial activity. These compounds are normally extracted from different parts of the fully growth plants. In this work, extracts were obtained from callus and cell suspension cultures of T. peruviana and their antimicrobial activity was evaluated by disk diffusion tests against gram negative (Salmonella thipimurium and Escherichia coli) and gram positive (Staphylococcus aureus and Bacillus cereus) strains. Ethanol, methanol and hexane extracts from callus and cell suspension cultures showed biological activity. Methanolic cell suspension extract showed activity against B. cereus and S. aureus. Ethanolic cell suspension extract inhibit all the bacteria, especially S. thipimurium while hexanic extract showed resistance activity against S. thipimurium, S. aureus and B. cereus. In terms of the source of the extracts, hexane extracts obtained from cell suspension cultures showed a higher antimicrobial activity compared to callus, while ethanol extracts had an inverse behavior. These results outline in vitro cell culture of T. peruviana as a feasible biotechnological platform for the production of compounds with antimicrobial activity.

Dos casos, uno de estenosis aórtica y otro de regurgitación aórtica, obtenidos de un sitio público, se han analizado para efectuar las comparaciones. Empleando el algoritmo computacional de Alineamiento Temporal Dinámico se evaluó la similitud que existe en la forma de las señales no patológicas y patológicas. Los resultados han ayudado a proponer las fronteras de decisión de separación entre las clases de señales.
Consumo de materia seca proveniente de diferentes especies forrajeras en cabras en Costa Rica
Authors: Elizondo-Salazar Jorge
Published: January 2019

Las explotaciones caprinas han jugado un papel muy importante en muchas culturas del mundo y en los últimos años, su población se ha visto aumentada debido a una creciente e importante demanda de alimentos ricos en proteína, consecuencia del crecimiento de la población humana y de una mayor exigencia en la calidad de los productos animales que consume. Dicha demanda ha sido en parte satisfecha con caprinos que, gracias a su condición de rumiantes, son capaces de procesar forrajes y residuos de cosechas no aptos para consumo humano, convirtiéndolos en alimentos de alta calidad nutricional. Sin embargo, con la apertura de los mercados y la globalización mundial, cualquier actividad productiva debe ser manejada eficientemente y la explotación caprina no escapa a esta exigencia. Para aumentar su producción hay que comprender que las cabras requieren de una alimentación rica en nutrientes presentes en la materia seca de los alimentos, pero cuando se considera este indicador en cabras, el rango de valores es poco conocido, por lo que el presente trabajo tiene el objetivo de presentar, a través de una revisión de literatura, los consumos de materia seca en cabras, provenientes de diferentes especies forrajeras, que reportan las diferentes investigaciones científicas llevadas a cabo en nuestro país. Los consumos de materia seca reportados en la literatura oscilan entre 250 y 1200 g por animal por día. Considerando la baja calidad nutricional de muchos de nuestros forrajes, es muy probable que con estos consumos los animales no estén llenando sus necesidades nutricionales, por lo que se deben buscar alternativas alimenticias y medidas de manejo que logren aumentar los consumos de materia seca y por ende, el consumo de nutrimentos en estos animales, de manera que puedan mejorar tanto su desempeño productivo como reproductivo.
Gênero, reciprocidade e mercado no cuidado de idosos
Authors: Araujo Anna Bárbara
Published: January 2019

Resumo: Este texto discute o tema do trabalho das cuidadoras de idosos que têm seus serviços agenciados por uma empresa de cuidado, com base num estudo de caso no centro da cidade do Rio de Janeiro. O trabalho dessas mulheres é analisado a partir da tensão entre duas lógicas: uma que prevê o cuidado plasmado por valores associados à reciprocidade e solidariedade, tidos como femininos, e outra marcada pela necessidade de profissionalização e de controle dos sentimentos. Os resultados da pesquisa sugerem que as duas lógicas - a da reciprocidade e a do mercado - competem na produção de demandas morais e emocionais do trabalho de cuidado, e que algumas cuidadoras operam estratégias de distanciamento do modelo familiar do cuidado de modo a valorizar seu próprio trabalho.
[ARTIGO RETRATADO] O mundo da vida e o mundo do texto em Úrsula, de Maria Firmina dos Reis
Authors: Dalcol Mônica Saldanha , Alós Anselmo Peres
Published: January 2019

Resumo: O romance Úrsula, de Maria Firmina dos Reis (2004), teve sua primeira publicação em 1859. Ele revela sua magnitude por dois aspectos: o primeiro, por ter sido o primeiro romance de autoria afrodescendente da literatura brasileira; o segundo, por ter sido o primeiro romance abolicionista escrito no Brasil. Nele, Maria Firmina dos Reis faz da escrita literária o palco da voz dos seus antepassados, onde os próprios sujeitos escravizados retratam, sob seus próprios pontos de vista, a questão da escravidão. A escrita de Maria Firmina dos Reis questiona a tradição escravocrata e patriarcal, marcada pela estigmatização e pela subalternização das comunidades afro-brasileiras e, consequentemente, por seu silenciamento durante séculos. Tendo em vista esses aspectos, a análise terá como pano de fundo a distinção desenvolvida por Paul Ricoeur em Do texto à ação: ensaios de hermenêutica (1989): o mundo do texto e o mundo da vida, assim como a discussão acerca da noção de mundo proposta por Antoine Compagnon em O demônio da teoria (2014).
Comparison of the collapse frequency and the probability of failure of bridges
Authors: Proske Dirk
Published: January 2019

In this paper, the collapse frequencies of bridges are summarised and compared with target values of probabilities of failure and with calculated failure probabilities for real bridges. The determination of the collapse frequencies is based on various publications in the sense of a meta-analysis. First, the various studies are summarised graphically, discussed and examined for a trend. The results show that the collapse frequencies decrease over time and that today they have reached a minimum. In the next step, the observed collapse frequencies, the target failure probabilities and the calculated failure probabilities are compared. There is a good agreement between the collapse frequencies and failure probabilities for real bridges. The collapse frequencies fulfil the current safety targets for time-dependent target probabilities as well as for time-independent target probabilities for dead and traffic loads. Subsequently, the causes of bridge collapses are assessed regarding loads. The main cause for bridge collapses is accidental loads, such as hydraulic events. Such loads can be controlled if they are considered in the correct order of magnitude. The probabilities of failure can be extended regarding further factors and thus the matching between probabilities and frequencies can be further improved.

Os visíveis e invisíveis na fotografia de Julia Kater
Authors: Falcão Grécia
Published: January 2019

A partir das colagens fotográficas da artista franco-paulistana Julia Kater, este artigo traça relações entre o campo de estudo da estética e da comunicação para abordar uma teoria visual que compreende as imagens para além dos critérios da representação. Em outras palavras, busco ultrapassar o entendimento da fotografia como mero objeto que captura aparências – e registra de forma fiel a realidadede – para compreender a imagem-técnica por meio de suas capacidades de ordenar e reordenar nossas maneiras de perceber o mundo. Vale dizer que esta abordagem teórica irá se situar sob a análise de fotografias que, na arte contemporânea, trabalham a subtração dos elementos visuais; a tal ponto que a negação visual que percorrem as obras de Julia Kater nos levarão a encarar a fotografia – imagem-técnica historicamente atribuída ao “fazer ver” – como visibilidade cujo significado opera mediante a constante tensão entre o “ver” e “não-ver”.
School Market in Quebec and the Reproduction of Social Inequalities in Higher Education
Authors: Kamanzi Pierre Canisius
Published: January 2019

The purpose of this article is to show that the stratification of the Quebec high school market contributes to the reproduction of social inequalities in higher education. The results obtained from a sample (N = 2,677) of a cohort of students born in 1984 and observed up to the age of 22 show that the influence of social origin operates in large part via mediation of the type of institution attended. Students enrolled in private or public institutions offering enriched programs (in mathematics, science or languages) are significantly more likely to access college and university education than their peers who attended a public institution offering only regular programs. Additional analyses reveal that the probability of attending a private or public institution offering enriched programs is strongly correlated with the social origin of the student. The influence of the education market itself operates through differences in performance and educational aspirations that characterize students in three types of establishments.
The Achievement of University Access: Conversion Factors, Capabilities and Choices
Authors: Walker Melanie
Published: January 2019

In the light both of persistent inequality of education opportunities for low income families and a wide equality gap in South Africa, this article explores students’ university access by applying Amartya Sen’s capability approach to a South African case study. The article demonstrates empirically that access is more than an individual project, shaped both by objective conditions and subjective biographies, that is by general conversion factors and a person’s social and personal options. Key conversion factors are material (income) and social (family, community, school, information), which produce an interlocking system of opportunity. Access thus requires more than formal opportunity to enable social mobility for all. The case study comprises qualitative interviews with diverse students in their first year at one university; illustrative narratives are selected to show different pathways, conversion factors and choices. Agency and self-efficacy emerge as especially important for making choices but also for constructing a higher education pathway where none exists for that person and her family. The article suggests that higher education has the potential to advance social mobility provided that it moves in the direction of expanding the capabilities of all students to have the choice of higher education.
Who Goes to College via Access Routes? A Comparative Study of Widening Participation Admission in Selective Universities in Ireland and England
Authors: O’Sullivan Katriona , Byrne Delma , Robson James , Winters Niall
Published: January 2019

This article explores changing national widening participation (WP) policy and responses from Higher Education institutions (HEIs) from a cross-national perspective. Specifically, the use of contextualised admissions and the provision of foundation year programmes in selective universities in Ireland and England are the key foci of interest. Using data gathered from WP students in two selective universities in Ireland and England, we explore how student characteristics differ according to the WP route undertaken. In an attempt to generate more knowledge of how HEIs enact WP policy, we draw on interviews conducted with staff involved in admission decision-making to explore how those with responsibility for admission within each institutional context perceive the WP pathways and their aims. The findings highlight how important it is for selective universities to adopt multiple WP pathways given that the use of contextualised admission and the provision of foundation years attract quite diverse student intakes. In both contexts, those entering through foundation years have experienced greater levels of disadvantage in terms of family history of education and family occupation compared to their contextualised admission counterparts. The qualitative findings reveal that those with responsibility for admission perceive the WP admission routes in different ways, highlighting a clash between institutional culture and the goals of WP.
