The new mineral melanarsite, K3Cu7Fe3+O4(AsO4)4, was found in the sublimates of the Arsenatnaya fumarole at the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure Eruption, Tolbachik volcano, Kamchatka Peninsula, Russia. It is associated with dmisokolovite, shchurovskyite, bradaczekite, hematite, tenorite, aphthitalite, johillerite, arsmirandite, As-bearing orthoclase, hatertite, pharmazincite, etc. Melanarsite occurs as tabular to prismatic crystals up to 0.4 mm, separate or combined in clusters up to 1 mm across or in interrupted crusts up to 0.02 cm × 1 cm × 1 cm covering basalt scoria. The mineral is opaque, black, with a vitreous lustre. Melanarsite is brittle. Mohs' hardness is ∼4 and the mean VHN = 203 kg mm–2. Cleavage was not observed and the fracture is uneven.Dcalcis 4.39 g cm–3. In reflected light, melanarsite is dark grey. Bireflectance is weak, anisotropism is very weak. Reflectance values [R1–R2, % (λ, nm)] are 10.5–9.4 (470), 10.0–8.9 (546), 9.7–8.7 (589), 9.5–8.6 (650). The Raman spectrum is reported. Chemical composition (wt.%, electron microprobe) is K2O 10.70, CaO 0.03, CuO 45.11, ZnO 0.24, Al2O30.32, Fe2O36.11, TiO20.12, P2O50.07, As2O536.86, total 99.56. The empirical formula, based on 20 O apfu, is (K2.81Ca0.01)∑2.82(Cu7.02Fe3+0.95Al0.08Zn0.04Ti0.02)∑8.11(As3.97P0.01)∑3.98O20. Melanarsite is monoclinic, C2/c,a= 11.4763(9),b= 16.620(2),c= 10.1322(8) Å, β = 105.078(9)°,V= 1866.0(3) Å3andZ= 4. The strongest reflections of the powder X-ray diffraction pattern [d,Å(I)(hkl)] are 9.22(100)(110), 7.59(35)(1₃11), 6.084(17) (111), 4.595(26)(1₃31, 220, 2₃21), 3.124(22)(3₃31, 1₃51), 2.763(20)(400, 1₃52), 2.570(23)(043) and 2.473(16) (260, 2₃61, 350). Melanarsite has a novel structure type. Its crystal structure, solved from single-crystal X-ray diffraction data (R= 0.091), is based upon a heteropolyhedral pseudo-framework built by distorted Cu(1–3)O6and (Fe,Cu)O6octahedra and As(1–3)O4tetrahedra. Two crystallographically independent K+cations are located in the tunnels and voids of the pseudo-framework centring eight- and seven-fold polyhedra. The name reflects the mineral being an arsenate and its black colour (from the Greek μέλαν, black).

Published: February 2017

A new protocol for the quantitative determination of zeolite-group mineral compositions by electron probe microanalysis (wavelength-dispersive spectrometry) under ambient conditions, is presented. The method overcomes the most serious challenges for this mineral group, including new confidence in the fundamentally important Si-Al ratio. Development tests were undertaken on a set of natural zeolite candidate reference samples, representing the compositional extremes of Na, K, Cs, Mg, Ca, Sr and Ba zeolites, to demonstrate and assess the extent of beam interaction effects on each oxide component for each mineral. These tests highlight the variability and impact of component mobility due to beam interaction, and show that it can be minimized with recommended operating conditions of 15 kV, 2 nA, a defocused, 20 μm spot size, and element prioritizing with the spectrometer configuration. The protocol represents a pragmatic solution that works, but provides scope for additional optimization where required. Vital to the determination of high-quality results is the attention to careful preparations and the employment of strict criteria for data reduction and quality control, including the monitoring and removal of non-zeolitic contaminants from the data (mainly Fe and clay phases). Essential quality criteria include the zeolite-specific parameters of R value (Si/(Si + Al + Fe3+), the 'E%' charge-balance calculation, and the weight percent of non-hydrous total oxides. When these criteria are applied in conjunction with the recommended analytical operating conditions, excellent inter-batch reproducibility is demonstrated. Application of the method to zeolites with complex solid-solution compositions is effective, enabling more precise geochemical discrimination for occurrence-composition studies. Phase validation for the reference set was conducted satisfactorily with the use of X-ray diffraction and laser-ablation inductively-coupled plasma mass spectroscopy.

Towards on-the-fly data post-processing for real-time tomographic imaging at TOMCAT
Authors: Marone Federica , Studer Alain , Billich Heiner , Sala Leonardo , Stampanoni Marco
Published: February 2017

Sub-second full-field tomographic microscopy at third-generation synchrotron sources is a reality, opening up new possibilities for the study of dynamic systems in different fields. Sustained elevated data rates of multiple GB/s in tomographic experiments will become even more common at diffraction-limited storage rings, coming in operation soon. The computational tools necessary for the post-processing of raw tomographic projections have generally not experienced the same efficiency increase as the experimental facilities, hindering optimal exploitation of this new potential. We present here a fast, flexible, and user-friendly post-processing pipeline overcoming this efficiency mismatch and delivering reconstructed tomographic datasets just few seconds after the data have been acquired, enabling fast parameter and image quality evaluation as well as efficient post-processing of TBs of tomographic data. With this new tool, also able to accept a stream of data directly from a detector, few selected tomographic slices are available in less than half a second, providing advanced previewing capabilities paving the way to new concepts for on-the-fly control of dynamic experiments.

Published: February 2017

When considering the acquisition of experimental synchrotron radiation (SR) X-ray CT data, the reconstruction workflow cannot be limited to the essential computational steps of flat fielding and filtered back projection (FBP). More refined image processing is often required, usually to compensate artifacts and enhance the quality of the reconstructed images. In principle, it would be desirable to optimize the reconstruction workflow at the facility during the experiment (beamtime). However, several practical factors affect the image reconstruction part of the experiment and users are likely to conclude the beamtime with sub-optimal reconstructed images. Through an example of application, this article presents SYRMEP Tomo Project (STP), an open-source software tool conceived to let users design custom CT reconstruction workflows. STP has been designed for post-beamtime (off-line use) and for a new reconstruction of past archived data at user’s home institution where simple computing resources are available. Releases of the software can be downloaded at the Elettra Scientific Computing group GitHub repository https://github.com/ElettraSciComp/STP-Gui.
Prospects for atomic resolution in-line holography for a 3D determination of atomic structures from single projections
Authors: Chen F. -R. , Kisielowski C. , Van Dyck D.
Published: February 2017

It is now established that the 3D structure of homogeneous nanocrystals can be recovered from in-line hologram of single projections. The method builds on a quantitative contrast interpretation of electron exit wave functions. Since simulated exit wave functions of single and bilayers of graphene reveal the atomic structure of carbon-based materials with sufficient resolution, we explore theoretically how the approach can be expanded beyond periodic carbon-based materials to include non-periodic molecular structures. We show here theoretically that the 3D atomic structure of randomly oriented oleic acid molecules can be recovered from a single projection.
Association Between Anesthesiology Volumes and Early and Late Outcomes After Cystectomy for Bladder Cancer: A Population-Based Study
Authors: Jaeger Melanie T. , Siemens D. Robert , Wei Xuejiao , Peng Paul , Booth Christopher M.
Published: February 2017

BACKGROUND:

Hospital and surgeon volume are related to postoperative complications and long-term survival after radical cystectomy. Here, we describe the relationships between these provider characteristics and anesthesiologist volumes on early and late outcomes after radical cystectomy for bladder cancer.

METHODS:

Records of treatment and surgical pathology reports were linked to the population-based Ontario Cancer Registry to identify all patients with radical cystectomy in Ontario during 1994 to 2008. Volume was divided into quartiles and determined on the basis of mean annual number of hospital/surgeon/anesthesiologist radical cystectomy cases during a 5-year study period. A composite anesthesiologist volume also was used and defined as major colorectal procedures in addition to radical cystectomy given the similar complexity of these cases. Logistic and Cox proportional hazards regression models were used to explore the associations between volume and outcomes while adjusting for potential patient-, disease-, and system-related confounders. The primary outcomes were postoperative readmission rates, postoperative mortality, and 5-year survival.

RESULTS:

The study included 3585 patients with radical cystectomy between 1994 and 2008. Median annual anesthesiologist radical cystectomy volume was 1 (maximum 8.8 cases/year); lowest volume quartile (Q1) <0.6 cases/year and highest volume quartile (Q4) >1.4 cases/year. The median annual composite anesthesiologist volume was 9 radical cystectomy and colorectal cases (Q1 [range 0.2–6.4 cases/year], Q4 [range 11.8–29.2 cases/year]); subsequent analyses used this composite volume. Anesthesiologist volume was associated with readmission rates at 30 days (P= .02, Q1 mean = 27% vs Q4 mean = 21%) and at 90 days (P= .01, Q1 mean = 39% vs Q4 mean = 31%). In multivariable analysis, including the adjustment for surgeon and hospital volume, the cohort of anesthesiologists who performed the lowest volume of cases annually (Q1) was associated with greater rates of readmission at 30 days (OR 1.36, 95% confidence interval [CI], 1.09–1.71,P= .04) and at 90 days (OR 1.36, 95% CI, 1.11–1.66,P= .03). Anesthesiologist volumes were not associated with postoperative mortality or long-term survival.

CONCLUSIONS:

Anesthesiologist case volume for radical cystectomy was low, reflecting the lack of subspecialization in urologic procedures in routine clinical practice. Lower volume anesthesia providers were associated with higher readmission rates after radical cystectomy. Further studies are needed to validate this finding and to identify the processes that may explain an association between provider volume and patient outcome.
Contemplative Spectator, Universal Art, Contingent Realities: Aesthetic Trajectories in Two Early “Art Films” In Malayalam
Authors: Joseph Jenson
Published: February 2017

For the earliest attempts in Malayalam cinema seeking to evolve a poetic aesthetic, the paradoxical relation toward urban modernity that emerged among the middle class by the middle of the twentieth century—defined by antagonism as well as fascination—operated as the axis around which new spectatorial relations could be maneuvered. This article takes up for discussion two Malayalam films from the mid-1950s—Newspaper Boy (dir. P. Ramadas, 1955) and Rarichan enna powran (Citizen Rarichan, dir. P. Bhaskaran, 1956)—as cinematic experiments in conceiving the urban space from two influential ideological positions, and as attempts in adapting to modernist idioms of international cinema. Modalities of imagining the urban space, the author argues, attained crucial historical significance in aesthetics and politics: it enabled the cultural producers to aesthetically situate the films within global cultures of cinema, thus invoking and molding the contemplative viewer; politically, these films mark the earliest attempts to conceive the region's relation to modernity through the grids of imagining the urban.
A key centriole assembly interaction interface between human Plk4 and STIL appears to not be conserved in flies
Authors: Cottee Matthew A. , Johnson Steven , Raff Jordan W. , Lea Susan M.
Published: February 2017

A small number of proteins form a conserved pathway of centriole duplication. In humans and flies, the binding of Plk4/Sak to STIL/Ana2 initiates daughter centriole assembly. In humans, this interaction is mediated by an interaction between the Polo-Box-3 (PB3) domain of Plk4 and the coiled-coil domain of STIL (HsCCD). We showed previously that the Drosophila Ana2 coiled-coil domain (DmCCD) is essential for centriole assembly, but it forms a tight parallel tetramer in vitro that likely precludes an interaction with PB3. Here we show that the isolated HsCCD and HsPB3 domains form a mixture of homo-multimers in vitro, but these readily dissociate when mixed to form the previously described 1:1 HsCCD:HsPB3 complex. In contrast, although Drosophila PB3 (DmPB3) adopts a canonical polo-box fold, it does not detectably interact with DmCCD in vitro. Thus, surprisingly, a key centriole assembly interaction interface appears to differ between humans and flies.
Acoustic measurements of post-dive cardiac responses in southern elephant seals (Mirounga leonina) during surfacing at sea

Published: February 2017

Measuring physiological data in free-ranging marine mammals remains challenging, owing to their far-ranging foraging habitat. Yet, it is important to understand how these divers recover from effort expended underwater, as marine mammals can perform deep and recurrent dives. Among them, southern elephant seals (Mirounga leonina) are one of the most extreme divers, diving continuously at great depth and for long duration while travelling over large distances within the Southern Ocean. To determine how they manage post-dive recovery, we deployed hydrophones on four post-breeding female southern elephant seals. Cardiac data were extracted from sound recordings when the animal was at the surface breathing. Mean heart rate at the surface was 102.4±4.9 beats.min−1 and seals spent on average 121±20 s breathing. During these surface intervals, the instantaneous heart rate is increasing with time. Elephant seals are supposed to drastically slow their heart rate (bradycardia) while they are deep underwater, and increase it (tachycardia) during the ascent towards the surface. Our finding suggests that tachycardia continues while the animal stays breathing at the surface. Also, the measured mean heart rate at the surface was unrelated to the duration and swimming effort of the dive prior to the surface interval. Recovery (at the surface) after physical effort (underwater) appears to be related to the overall number of heart beats performed at the surface, and therefore total surface duration. Southern elephant seals recover from dives by adjusting the time spent at the surface rather than their heart rate.
Is human Achilles tendon deformation greater in regions where cross-sectional area is smaller?
Authors: Reeves Neil D. , Cooper Glen
Published: February 2017

The Achilles is a long tendon varying in cross-sectional area (CSA) considerably along its length. For the same force, a smaller CSA would experience higher tendon stress and we hypothesised that these areas would therefore undergo larger transverse deformations. A novel magnetic resonance imaging-based approach was implemented to quantify changes in tendon CSA from rest along the length of the Achilles tendon under load conditions corresponding to 10, 20 and 30% of isometric plantar flexor maximum voluntary contraction (MVC). Reductions in tendon CSA occurring during contraction from the resting condition were assumed to be proportional to the longitudinal elongations within those regions (Poisson’s ratio). Rather than tendon regions of smallest cross-sectional area undergoing the greatest deformations, the outcome was region-specific with the proximal (gastrocnemius) tendon portion showing larger transverse deformations upon loading compared to the distal portion of the Achilles (P<0.01). Transverse tendon deformation only occurred in selected regions of the distal Achilles tendon at 20% and 30% of MVC, but in contrast occurred throughout the proximal portion of the Achilles at all contraction levels (10, 20 and 30% of MVC; P<0.01). Calculations showed that force on the proximal tendon portion was ∼60% lower, stress ∼70% lower, stiffness ∼30% lower and Poisson’s ratio 6-fold higher compared to the distal portion of the Achilles tendon. These marked regional differences in mechanical properties may allow the proximal portion to function as a mechanical buffer to protect the stiffer, more highly stressed, distal portion of the Achilles tendon from injury.
Оценка порядка аппроксимации матричного метода численного интегрирования краевых задач

Published: February 2017

Представлено первое сообщение цикла из двух статей, в котором исследованы закономерности изменения порядка аппроксимации матричного метода численного интегрирования в зависимости от используемой степени в разложении в многочлене Тейлора решений краевых задач для систем обыкновенных дифференциальных уравнений второго порядка с переменными коэффициентами с граничными условиями первого рода.
Использование многочлена Тейлора второй степени при аппроксимации производных конечными разностями приводит ко второму порядку аппроксимации традиционного метода сеток. В работе при исследовании краевых задач для систем обыкновенных дифференциальных уравнений второго порядка рассмотрен предложенный ранее метод численного интегрирования, использующий средства матричного исчисления, в котором аппроксимация производных конечными разностями не производилась. Согласно указанному методу, при составлении системы разностных уравнений может быть выбрана произвольная степень многочлена Тейлора. Вычислена невязка и дана оценка порядка аппроксимации метода в зависимости от выбранной степени многочлена Тейлора. Теоретически показано, что для краевой задачи с граничными условиями первого рода порядок аппроксимации метода возрастает с увеличением степени многочлена Тейлора и равен этой степени лишь для ее четных значений. Для нечетных значений степени порядок аппроксимации меньше этой степени на единицу. Теоретические выводы подтверждены численным экспериментом для краевых задач с граничными условиями первого рода.
Requirements for Intermediaries and Advisors in the Area of Mortgages Resulting from Mortgage Credit Directive– Implications for Poland
Authors: Waliszewski Krzysztof
Published: February 2017

The dynamic development of the mortgage market, especially in the period before the current financial crisis, revealed that within the EU there are local mortgage credit markets and that it is necessary to harmonize the rules of the system and consumer protection within the Community. The intention of the creators of the Mortgage Credit Directive was to organize the mortgage lending market for residential purposes and make it transparent, as well as increase the safety of the consumer credit market, along the lines of what took place earlier in the consumer credit market regulations (The Consumer Credit Directives no. 2008/48/EC and earlier no. 87/102/EEC). The Mortgage Credit Directive implies for lenders - credit institutions to act at every stage of the lending process with respect to the consumer’s interest and to provide them with adequate services for their needs. Due to the large role of indirect distribution channels of mortgages by banks there are certain requirements for intermediaries, brokers and credit advisors. The implementation term of the Directive, appointed for March 2016, implies action to be taken in order to implement the provisions of this Directive into Polish law. The legislative process is being conducted by the Ministry of Finance and supported by the Group on implementation of the Mortgage Credit Directive operating with the Council of Financial Market Development.

In this paper we investigate sources and characteristics of value, size and momentum profits on the Polish stock market. The research aims to broaden the academic knowledge in a few ways. First, we deliver fresh out-of-sample evidence on value, momentum, and size premiums. Second, we analyze the interdependences among the factors. Third, we investigate whether the factor premiums are present after accounting for liquidity constraints. Fourth, we check whether the factor premiums are robust to transaction costs. Our research is based on all the stocks listed on the WSE in years 2001-2013. We find, that the value, momentum, and size premiums are to some extent present on the Polish market. Furthermore, they strengthen each other, but they disappear after accounting for transaction costs and liquidity.

Recent Aspects on the Effect of Inclusion Characteristics on the Intragranular Ferrite Formation in Low Alloy Steels: A Review
Authors: Mu Wangzhong , Jönsson Pär Göran , Nakajima Keiji
Published: February 2017

Intragranular ferrite (IGF), which nucleates from specific inclusion surfaces in low alloy steels, is the desired microstructure to improve mechanical properties of steel such as the toughness. This microstructure is especially important in the coarse grain heat affected zone (CGHAZ) of weldments. The latest review paper focusing on the role of non-metallic inclusions in the IGF formation in steels has been reported by Sarma et al. in 2009 (ISIJ int., 49(2009), 1063–1074). In recent years, large amount of papers have been presented to investigate different issues of this topic. This paper mainly highlights the frontiers of experimental and theoretical investigations on the effects of inclusion characteristics, such as the composition, size distribution and number density, on the IGF formation in low carbon low-alloyed steels, undertaken by the group of Applied Process Metallurgy, KTH Royal Institute of Technology. Related results reported in previous studies are also introduced. Also, plausible future work regarding various items of IGF formation is mentioned in each section. This work aims to give a better control of improving the steel quality during casting and in the heat affected zone (HAZ) of weldment, according to the concept of oxide metallurgy.

In this paper, the Kuramoto-Sivashinsky equation is solved numerically by implementing a new differential quadrature technique that uses quintic B-spline as the basis functions for space integration. The derivatives are approximated using differential quadrature method. The weighting coefficients are obtained by semi-explicit algorithm including an algebraic system with penta-diagonal coefficient matrix that is solved using the five-band Thomas algorithm. Stability analysis of method has also been done. The accuracy of the proposed scheme is demonstrated by applying on five test problems. Some theoretical properties of KS equation like periodicity, monotonicity and dissipativity etc. have also been discussed. The results are also shown graphically to demonstrate the accuracy and capabilities of this method and comparative study is done with results available in literature. The computed results are found to be in good agreement with the analytical solutions.
Inhärentes oder externes ethos der Medizin?
Authors: Ringkamp Daniela
Published: February 2017

Der Beitrag argumentiert dafür, medizinische Notsituationen nicht durch ein eigenes, ausschließlich im medizinischen Tätigkeitsbereich geltendes Moralprinzip zu regulieren, sondern durch moralische Grundlagen zu normieren, die auch außerhalb der Medizin und des ärztlichen Berufsstandes Geltung beanspruchen. Ansatzpunkt ist dabei die Gegenüberstellung medizinischer und nicht-medizinischer Notfälle in Derek Parfits Emergency Principle aus dem fünfzehnten Kapitel von On What Matters. Parfit fordert, medizinischen Notlagen mit einem Instrumentalisierungsverbot zu begegnen, das den Patienten vor ärztlichen Inanspruchnahmen schützt. Durch Bezug zu den konträren Positionen von Edmund D. Pellegrino und Robert M. Veatch über die Möglichkeit eines der Medizin inhärenten ethos wird verdeutlicht, dass Parfits Argumentation insgesamt nicht überzeugt. Dies zeigt sich insbesondere ausgehend von Veatchs Bestimmung der Medizin als einer Praxis, deren Handlungsfelder von unterschiedlichen Akteuren und Intentionen gesteuert werden. Dieser Pluralismus spricht für die Plausibilität einer der Medizin externen Moral, die auch moderate Formen der Instrumentalisierung in der Medizin erlaubt.

Los conceptos del enfoque funcionalista propuestos por Nord (1997), la perspectiva discursiva de Hatim (1997), la noción de ironía de Barbe (1995) y las estrategias encubiertas planteadas por Brown y Levinson (1987) constituyeron la base teórica de la investigación que reportamos en este artículo. Para la recopilación, delimitación y análisis del corpus utilizamos una metodología empírico–descriptiva de corte cualitativo. El análisis de los datos se realizó desde una perspectiva semántica y pragmática. Como resultado, encontramos que la traducción de la ironía, identificada en el texto base a través de sus participantes, se conservó en el texto meta, precisamente en aquellos casos en los cuales se mantuvo el incumplimiento de las máximas conversacionales. Se concluye que este incumplimiento es un recurso válido para transmitir la ironía en la traducción de un texto literario.

Published: February 2017

Perairan rawa yang terdiri atas rawa pasang surut dan rawa lebak, merupakan habitat yang baik bagi ikan sebagai tempat mencari makan, tempat mengasuh anak, dan tempat memijah. Perairan rawa memiliki karakteristik fisik, kimia, dan biologi yang khas, pada umumnya banyak terdapat tumbuhan air, kandungan O2, dan pH rendah, sebaliknya CO2 relatif tinggi, karena banyak terjadi proses dekomposisi. Jenis-jenis ikan yang mendominasi perairan rawa adalah ikan-ikan yang mempunyai alat pernafasan tambahan (labirin), sehingga dapat mengambil oksigen langsung dari udara. Jenis ikan tersebut, disebut ikan hitam (black fish) seperti tembakang (Helostoma temmincki),betok (Anabas testudineus), sepat siam (Trichogaster pectoralis), sepat rawa (Trichogaster trichopterus) dan lain-lain. Labirin terletak di bagian atas rongga insang, terdiri atas lapisan-lapisan kulit yang berlekuk-lekuk dan mengandung banyak pembuluh darah. Ada organ labirin merupakan bentukpenyesuaian terhadap kondisi jelek di suatu perairan, terutama pada kondisi oksigen rendah di saat musim kemarau.

KERAGAAN TEKNIS KAPAL RISET SARDINELLA SEBAGAI TRAWLER
Authors: Nurdin Erfind
Published: February 2017

Pada awal tahun 1996 Kapal Riset (KR) Sardinella didesain untuk alat tangkap pukat cincin (purse seine). Karena kebutuhan akan wahana penelitian untuk mengambil contoh (sampel) sumberdaya ikan demersal, maka tahun 2004 fungsi diubah menjadi kapal trawl dasar (bottom trawl). Untuk itu, beberapa perubahan dilakukan terhadap KR. Sardinella, antara lain tata letak (layout) bagian buritan, penambahan gardan sebagai penarik tali selambar. Dengan perubahan tersebut, diharapkan KR. Sadinella mencapai kinerja yang memadai sebagai trawler. Guna mengetahui keragaan teknis (tingkat keberhasilan operasional dan laju tangkap) KR. Sardinella sebagai trawler, maka telahdilakukan penelitian melalui uji coba pada bulan September 2005 dan September 2006. Spesifikasi trawl yang dioperasikan di KR. Sardinella adalah panjang tali ris atas (head rope) 21 m dan tali ris bawah (ground rope) 24 m. Lokasi penangkapan adalah pada kedalaman 15 - 35 m, lama penarikan jaring rata-rata 1 jam pada kecepatan kapal rata-rata 2,5 knot. Keragaan teknis KR. Sardinella sebagai trawler baik dengan tingkat keberhasilan dalam pengoperasian mencapai sekitar 90%. Laju tangkap KR. Sardinella sebagai trawler cukup baik dengan rata-rata 16,43 kg/jam/ operasi trawl (setting) dari17 stasiun pada tahun 2005 dan17,95 kg/jam/operasi trawl (setting) dari 24 stasiun pada tahun 2006.

Survivor, Warrior, Mother, Savior
Authors: Faithful George
Published: February 2017

The late Cold War saw the advent of a new paradigm of woman as hero in apocalyptic English-language science fiction film at its intersection with the horror and action sub-genres. In contrast to the helpless, villainous, and overly sexualized female characters before them, the Alien films’ Ellen Ripley and the Terminator franchise’s Sarah Connor represented practical, courageous women who saved humanity through their actions. These ostensibly secular narratives were rich with religious themes such as incarnation, kenosis, resurrection, faith seeking understanding, messianic expectation, virgin birth, free will, fate, evil, prophetic forewarning, and salvation. They were foundational in establishing, in effect, a humanistic mythos.
The Sphero-conical Vessel
Authors: Pradines Stéphane
Published: February 2017

The six articles presented in this special edition of the Journal of Islamic Archaeology were part of the Study Day held on the 17th of December 2014 at the French Institute of Oriental Archaeology (the “IFAO”), Cairo and entitled “the Sphero-conical vessel: A debate on fire grenades and gunpowder in the Muslim World.”
Medieval Islamic Fire Grenades
Authors: Nicolle David
Published: February 2017

Some fragments of broken sphero-conical vessels were found in one of the southern Towers of the Citadel of Damascus. Though not unusual in themselves, these fragments are of particular interest because they formed part of a cache of Islamic military equipment dating from the 13th and 14th centuries. Such an association might lend weight to the theory that such vessels had a military function; for example being used as incendiary or even semi-explosive grenades. This article considers such a possibility and compares the fragments with others found across a large part of the medieval Islamic world, and indeed beyond. The article also offers a survey of historical, archaeological and iconographic evidence for the use of incendiary grenades within medieval Islamic military tradition and technology.
Sphero-conical Vessels from Baalbek
Authors: Vezzoli Valentina
Published: February 2017

Recent archaeological excavations in the area of Bustan Nassif, south of the citadel of Baalbek, by the DAI-Berlin, BTU-Cottbus and DGA-Lebanon, have brought to light an important urban sector occupied during the Middle Islamic period with public buildings (mosque, hamm?m, kh?n) and private houses, crossed by a main arterial road connecting one of the city gates to the city centre. A significant quantity of ceramics has been unearthed in this sector, documenting the history of common ware and fine ware productions on the site from the 12th through the early 15th centuries. Among these are numerous sphero-conical vessels from the north-eastern area, which bears witness to an important military destruction. In addition to the assemblage from Bustan Nassif, the site of Baalbek has produced numerous sphero-conical vessels from unstratified and secondary contexts. This material is particularly rich and varied, in terms of fabric, form, and surface treatment, also including some glazed items. An important sub-group of these vessels is incised with inscriptions or symbols, executed after firing, providing new perspectives on object use. The rich variety of the Baalbek assemblage recovered from good stratigraphic contexts provides new clues for understanding the function(s) of sphero-conical vessels.
Uma proposta de leitura de poesia a partir do acervo do PNBE
Authors: Alves José Helder Pinheiro
Published: February 2017

Pesquisas realizadas ao longo das três últimas décadas revelam que o trabalho com o poema no nível médio de ensino segue um padrão historicista que pouco contribui para a formação de leitores. Por outro lado, experimentos realizados em diferentes séries do ensino básico, lançando mão de uma metodologia de viés interacionista, têm como resultado um envolvimento efetivo do jovem leitor na construção dos sentidos do poema. Neste artigo, apresentaremos e discutiremos uma pesquisa voltada para o ensino de literatura no nível médio, bem como o resultado de um levantamento sobre o impacto do Programa Nacional Biblioteca da Escola (PNBE) no ensino de literatura em cinco escolas públicas de Campina Grande, Paraíba. Serão observados os possíveis usos do acervo deste importante programa de socialização de obras literárias no trabalho com o texto literário. Por fim, será apresentada uma proposta de abordagem de um dos livros de poemas selecionados para o acervo do PNBE – 2013. O intuito é, a partir de um diagnóstico das pesquisas sobre o trabalho com o poema e do aproveitamento (ou não) do acervo do PNBE no ensino médio, apontar algumas perspectivas metodológicas de trabalho com a poesia, privilegiando o diálogo texto-leitor. Fundamentamo-nos, sobretudo, nas contribuições acerca da Estética da Recepção, apostando em novas propostas metodológicas para o trabalho com o texto literário em sala de aula, notadamente o poema.
El aborto en cuestión: la individuación y juridificación en tiempos de neoliberalismos
Authors: Brown Josefina ,   Universidad de Buenos Aires,  Argentina
Published: February 2017

Resumen: Este artículo recoge algunas reflexiones teóricas ligadas a una investigación empírica en torno a los derechos sexuales y (no) reproductivos, en la intersección entre los discursos sociopolíticos y las experiencias personales, con el objetivo de contribuir a comprender las dificultades para discutir pública y políticamente sobre aborto, en Argentina en particular y en Latinoamérica en general. El debate se plantea en el marco de contextos neoliberales ligados a procesos de políticas de individuación y juridificación/judicialización de los problemas sociales, incluyendo la cuestión del aborto. La hipótesis planteada apunta a subrayar las complejidades que supone la concepción de individuo vigente en el marco del neoliberalismo, a diferencia del individuo de la “sociedad organizada”, así como a resaltar las dificultades particulares que devienen del pasaje del énfasis en un discurso biomédico a otro jurídico en torno de las sexualidades. Se trata de dos problemas nodales: uno, ligado con la cuestión de lo que supone la individuación; y el otro, lo que implica la solapada persistencia del sujeto abstracto, base del sujeto de derecho, y que oblitera todas las diferencias, incluidas las económicas y sociales entre las personas (mujeres, en este caso). Asimismo se enfatiza la insistencia en la conciencia, la voluntad, la libertad, pero sobre todo, la responsabilidad que se exige al individuo neoliberal (retomando la noción de individuo liberal clásica pero actualizada a los tiempos que corren) y que se traduce, en caso del aborto, en la dificultad para tolerar la “falla” que deviene de la imposibilidad de prevenir exitosamente todos los riesgos, en el marco del ejercicio de la sexualidad que se impone ahora como libre, voluntaria, consentida, responsable y placentera.
Espaço e sociabilidades: entre o beco e o gueto
Authors: Ribeiro Andressa de Freitas ,   Universidade Federal da Bahia,  Brazil
Published: February 2017

Resumo: Este artigo reflete sobre o Beco dos Artistas, lugar localizado em Salvador, capital do estado da Bahia. O Beco dos Artistas é um local onde atualmente encontram-se quatro bares, e que se caracteriza por ser um espaço de sociabilidade GLS. Para muitos, é um gueto gay. No entanto, o Beco dos Artistas nem sempre foi considerado um lugar para homossexuais. No final dos anos setenta e início dos anos oitenta, manteve um vínculo muito forte com as classes artísticas e intelectuais de Salvador, e seu nome deriva disso. Meu propósito é refletir sobre a mudança de significados atribuídos ao Beco dos Artistas ao longo de sua história em termos de identidade e considerar como marcadores sociais como raça, classe e sexualidade contribuíram para a estigmatização atual do lugar. Os dados aqui analisados foram obtidos através de observação etnográfica realizada de 2008 a 2010.
El fantasma de la puta-peluquera: Género, trabajo y estilistas trans en Cali y San Andrés Isla, Colombia
Authors: Posso Jeanny Lucero ,   Universidad del Valle, Colombia, Furcia Ange La ,   Escuela Normal Superior de Paris, França
Published: February 2017

Resumen: A través de un uso crítico de la perspectiva de la interseccionalidad, la investigación etnográfica y exploratoria analiza las imbricaciones del género, la clase social, la etnicidad y la sexualidad en las trayectorias laborales de un conjunto de estilistas transfemeninas en Santiago de Cali y San Andrés Isla, Colombia. Las distancias sociales que se construyen entre diferentes actores (estilistas gais, estilistas de clase alta blancos heterosexuales, personas raizales heterosexuales y la clientela cisgénero) producen de manera específica los sentidos otorgados al trabajo en las peluquerías y sus fronteras difusas con la prostitución. Si por un lado el efecto de clase y la dominación cisgenerista imposibilitan el ascenso social de las mujeres trans caleñas, el tabú heterosexista del sistema étnico prohíbe y niega las feminidades trans como parte de la identidad raizal.
