Weighing the Darkness: Astrometric Mass Measurement of Hidden Stellar Companions Using Gaia
Authors: Andrews Jeff J. , Breivik Katelyn , Chatterjee Sourav
Published: November 2019

In astrometric binaries, the presence of a dark, unseen star can be inferred from the gravitational pull it induces on its luminous binary companion. While the orbit of such binaries can be characterized with precise astrometric measurements, constraints made from astrometry alone are not enough to measure the component masses. In this work, we determine the precision with which Gaia can astrometrically measure the orbits and—with additional observations—the component masses, for luminous stars hosting hidden companions. Using realistic mock Gaia observations, we find that Gaia can precisely measure the orbits of binaries hosting hidden brown dwarfs out to tens of parsecs and hidden white dwarf and neutron star companions at distances as far as several hundred parsecs. Heavier black hole companions may be measured out to 1 kpc or farther. We further determine how orbital period affects this precision, finding that Gaia can characterize orbits with periods as short as 10 days and as long as a few 103 days, with the best measured orbits having periods just short of Gaia’s mission lifetime. Extending Gaia’s nominal five-year mission lifetime by an additional five years not only allows for the measurement of longer period orbits, but those longer period binaries can be seen at even greater distances.
A Look at Phase Space Intermittency in Magnetized Plasma Turbulence
Authors: Teaca Bogdan , Navarro Alejandro Bañón , Told Daniel , Görler Tobias , Plunk Gabriel , Hatch David R. , Jenko Frank
Published: November 2019

In a proton–electron magnetized plasma, we analyze turbulence at kinetic scales captured by a gyrokinetic formalism. The interval of scales spans the range between the proton and the electron gyroradii, while the use of the proper mass ratio between the two species ensures a realistic scale separation for the nonlinear couplings. The simulation is pertinent to astrophysical conditions, employing a straight field line magnetic geometry for the guide field, a plasma β of one, and a temperature ratio between the two species of unity. We investigate the intermittency of the distribution functions in the perpendicular direction, measured over the phase space as a way to account for the velocity space structures generated via Landau damping as well as for the nonlinear spatial mixing (i.e., the turbulent cascade). The analysis makes use of a Hermite decomposition in the parallel velocity. Electron structures are found to be strongly intermittent compared to weakly intermittent protons. Moreover, we find evidence linking intermittency with phase mixing and electron Landau damping, as intermittent electron structures also exhibit strong parallel velocity structures.
Light Bridge Brightening and Plasma Ejection Driven by a Magnetic Flux Emergence Event
Authors: Yang Xu , Yurchyshyn Vasyl , Ahn Kwangsu , Penn Matt , Cao Wenda
Published: November 2019

Observations with the Goode Solar Telescope (GST) are presented here showing that the emergence of 1.91 × 1018 Mx of new magnetic flux occurred at the edge of a filamentary light bridge (LB). This emergence was accompanied by brightness enhancement of a photospheric overturning convection cell (OCC) at the endpoints of the emerging magnetic structure. We present an analysis of the origin and the dynamics of this event using high-resolution GST Fe i 1564.85 nm vector magnetic field data, TiO photospheric, and Hα chromospheric images. The emerged structure was 1.5 × 0.3 Mm in size at the peak of development and lasted for 17 minutes. Doppler observations showed presence of systematic upflows before the appearance of the magnetic field signal and downflows during the decay phase. Changes in the orientation of the associated transverse fields, determined from the differential angle, suggest the emergence of a twisted magnetic structure. A fan-shaped jet was observed to be spatially and temporally correlated with the endpoint of the OCC intruding into the LB. Our data suggest that the emerging fields may have reconnected with the magnetic fields in the vicinity of the LB, which could lead to the formation of the jet. Our observation is the first report of flux emergence within a granular LB with evidence in the evolution of vector magnetic field, as well as photosphere convection motions, and supports the idea that the impulsive jets above the LB are caused by magnetic reconnection.
A Global Magnetohydrodynamic Simulation Study of Ultra-low-frequency Wave Activity in the Inner Magnetosphere: Corotating Interaction Region + Alfvénic Fluctuations

Using global magnetohydrodynamic (MHD) simulations, we investigate the role played by a complex solar structure composed of a corotating interaction region (CIR) followed by solar wind Alfvénic fluctuations on the magnetosphere’s nightside, equatorial electric field oscillations in the ultra-low-frequency range. A series of numerical experiments are performed employing synthetic solar wind inputs resembling those of a real CIR+Alfvénic fluctuation event that reached Earth’s magnetosphere on 2003 April 20. The following is found: (i) Radial electric field component fluctuations are excited via magnetopause boundary motions driven either by solar wind density variations characteristic of CIRs or by solar wind Alfvénic fluctuations with a given oscillation period. (ii) Azimuthal electric field component fluctuations nearer to Earth, that is, at radial distances R less than about 5R
E (

Earth radius), are apparently not related to either of the two types of sinusoidal solar wind Alfvénic fluctuations used in this study featuring monochromatic frequencies of 0.833 mHz (20-minute period) and 1.666 mHz (10-minute period). Instead, these innermost azimuthal component fluctuations show enhanced activity when inner magnetosphere convection increases as a result of a southward turning of the interplanetary magnetic field component B

z
. (iii) Lastly, outermost (R ≳ 7 R
E) azimuthal electric field oscillations weakly respond to monochromatic solar wind Alfvénic fluctuations by showing power spectral density peaks at both driving frequencies, but only near the flanks of the magnetopause, thus suggesting that such oscillations are being excited also owing to magnetopause boundary motions driven by solar wind Alfvénic fluctuations.
Communist history, police history and the archives of British state surveillance
Authors: Morgan Kevin
Published: November 2019

In Britain as in other countries security service files have come to provide an important resource for the writing of communist history. This paper discusses some of practical, ethical and methodological challenges they pose for historians. In Britain the selective release of small
batches of redacted files was undertaken from the 1990s as part of the post-Cold War rebranding of the MI5 state security service. No meaningful public consultation took place regarding the principles governing the release of these materials. Nor were details made available of the scope of
state surveillance or of the individuals and organisations subjected to it. The lack of transparency and accountability was compounded by the asymmetry between observers and observed and the withholding of information regarding the identities, associations and career histories of security
operatives. Drawing on published and unpublished examples, the paper characterises this as a project for the 'securitisation' of communist and wider left history: one that seeks to validate MI5's past and continuing role by accentuating issues of espionage while filtering and in many cases
destroying evidence of the routine surveillance of political and social movement activism.
On Pierre Bourdieu's Legal Thought
Authors: García Villegas Mauricio
Published: November 2019

Commentaires sur Pierre Bourdieu et le droit. Dans cet article, l’auteur analyse la contribution de Bourdieu à la sociologie du droit à partir d'une perspective comparée. L’hypothèse développée est la sui-vante : les analyses de Bourdieu sur le droit se comprennent mieux si on les examine en ayant à l’esprit l’opposition entre sociologues et juristes en France. De même, l’auteur montre que cette approche du droit par Bourdieu liée à sa théorie de la domination politique est influencée par une vision étato-centrée fortement en relation avec l’histoire politique de la France et qui ne prend pas en compte les mutations actuelles de la régulation juridique. Riche théori-quement, la sociologie du droit de Bourdieu est néanmoins marquée par le contexte dans lequel elle a été produite.
Les activités curriculaires des enseignants d’EPS, entre prescription et liberté : une revue de littérature
Authors: Lenzen Benoît
Published: November 2019

Ce texte se propose de passer en revue les connaissances empiriques sur le rôle des enseignants d’éducation physique et sportive (EPS) dans l’élaboration des curricula et sur les curricula en EPS qui en résultent. S’appuyant sur un modèle d’analyse existant de l’activité de l’enseignant et sur une recension des principaux travaux conduits ces vingt dernières années sur la problématique étudiée (corpus de 62 recherches), cette revue de littérature confirme l’influence de déterminants institutionnels, personnels et relatifs au public scolaire sur les pratiques curriculaires des enseignants d’EPS. Les curricula qui en résultent apparaissent « s’alimenter à la même source » si on considère leur référence quasi unanime à un univers culturel existant en dehors de l’école, largement représenté par les APS institutionnellement organisées par les fédérations et associations sportives. En revanche, ils se différencient plus nettement lorsqu’on prend en compte la mise en forme scolaire de leurs pratiques sociales de référence. La surreprésentation du contexte français, de l’enseignement secondaire et des études ayant investigué le curriculum déclaré et non le curriculum réellement mis en œuvre par les enseignants d’EPS limite toutefois la portée des résultats de cette revue de littérature.
L’art du piratage à l’ère de la playlist
Authors: Christoffel David
Published: November 2019

S’il y a des exemples historiques de radios pirates dont la programmation musicale n’avait rien de transgressive, il peut y avoir beaucoup d’exemples de musiques aux accents subversifs promues sur des radios officielles. Mais si radios pirates et musiques contre-officielles s’interpénètrent de manière irrégulière, qu’en est-il des « playlists » ? En s’appuyant sur des exemples récents où l’imaginaire pirate a été mobilisé au cours d’émissions légales (Radio Campus Clermont-Ferrand/Radio Galère, Radio Klaxon et, plus en détail, les œuvres du collectif PI-node), cette étude cherche à réfléchir à l’éditorialisation spécifique de la musique en playlists en contexte de piraterie radiophonique, à partir d’Un manifeste hacker de McKenzie Wark.

An Investigation of Ingots Teemed under Different Thermal and Physical Solidification Conditions and the Analysis of Metal Quality of the Hollow Forgings Produced
Authors: Gamanyuk Sergey B. , Rutskiy Dmitriy V. , Zyuban Nikolay A.
Published: November 2019

Optical and electron microscopy are used in the paper to analyze the quality of the cast metal of a 1.53 ton ingot of steel 38ХН3МФАteemed with a cooling feeder head. In addition, the analysis of the metal of hollow forgings produced from ingots with “cooled” and thermally insulated feeders is performed. A metallographic study reveals that if the ingot top is cooled down, it results in an accelerated solidification throughout the entire mass of the ingot; in addition, the thermal centre shifts to the ingot central axial area.

Prevalence of the Anterior Occipital Sulcus in the Human Brain: Anatomical Study
Authors: Addas Bassam MJ
Published: November 2019

The objective of this article is to investigate the prevalence of the anterior occipital sulcus in the human brain. The external surface of 25 consecutive formalin fixed brains (50 hemispheres) were examined for the presence of the anterior occipital sulcus. The anterior occipital sulcus was identified in 11 (22%) hemispheres, seven on the right side and four on the left side. The sulcus length ranged from 1-5 cm with a mean length of 2.89 cm. The mean distance from the occipital lobe tip to the anterior occipital sulcus was 4.75 cm on the right side and 5 cm on the left side. The anterior occipital sulcus can be infrequently encountered in human brains (22%); when present it represents the posterior limit of the temporal lobe and the anterior limit of the occipital lobe.

Ovarian ossification is a rare pathological condition that may be encountered in neoplastic as well as in non-neoplastic contexts. Its etiology and pathogenesis are controversial. We report the case of a 33-year old female (P6 + 1) who presented with a 4 month history of abdominal distention and amenorrhea. Radiological investigations showed complex pelviabdominal mass with foci of calcification. The patient underwent total hysterectomy with bilateral salpingo-oophorectomy. Gross pathology findings showed bilateral enlargement of the ovaries and gritty sensation of ovary in slicing. Microscopic pathology showed mature lamellate bone in the wall of right ovary invaded by serous neoplastic cells.
Preservation of the Anterior Branch of the Great Auricular Nerve during Benign Parotid Neoplasm Excision
Authors: Alghamdi Khalid B.
Published: November 2019

The aim of this study is to examine the impact of the process of preservation of both divisions of great auricular nerve on patients' quality of life. This is a retrospective study conducted at King Abdulaziz University Hospital after receiving formal consent from the research ethics committee. For the analysis, charts of all patients who underwent partial parotidectomies (superficial parotidectomies) for benign neoplasm were evaluated and the results were validated. A total 45 cases of superficial parotidectomies were observed, out of which, 15 had preservation of the great auricular nerve (anterior and posterior divisions), and numbness and feeling of well-being were better in this group as compared to the great auricular nerve anterior division sacrifice group. The influence of great auricular nerve sacrifice morbidity on patient’s quality of life varied. Great auricular nerve morbidity requires further eff orts to be made in order to preserve the posterior and anterior branches of this nerve when possible and in the case of the benign lesion, it is considered more suitable.
Asymptomatic Bacteriuria among Women Attending the Antenatal Clinics in Jeddah, Western Region of Saudi Arabia
Authors: Ali Shamrani Hanan M.
Published: November 2019

This retrospective chart review was conducted to determine the proportion of pregnant women with asymptomatic bacteriuria who were followed up at the antenatal clinics of King Abdulaziz University Hospital, Jeddah between January 2007 and January 2012. Clinical and paraclinical data were recorded for 337 women in their last trimester of pregnancy. The prevalence of asymptomatic bacteriuria in the cohort was 31.26%. The most frequently isolated bacteria included Escherichia coli and Klebsiella pneumoniae in 30.39% and 10.78% of the cases, respectively. In most cases, the isolated bacteria were sensitive to ampicillin (11.57%), amoxicillin (10.38%), and amikacin (5.63%). Most bacteria were resistant to nitrofurantoin (21.06%), tetracycline (21.06%) and cefixime (20.77%). The most common prescribed medications included multivitamins (n = 40; 11.87%), vitamin B12 (n = 47; 13.95%), folic acid (n = 45; 13.35%), and antibiotics (n = 43; 12.75%). Overall, it is possible that pregnant women with asymptomatic bacteriuria are undertreated at our institution. Gaps in the management of these patients should be identified to improve patient care.
Inferring Transcription Factors and microRNAs Associated with Elevated Expression of the Oncogenic B-Cell Lymphoma 11A in Triple Negative Breast Cancer
Authors: Laqtom Nouf N. , Algothmi Khloud M. , Bakhribah Amani H.
Published: November 2019

B-cell lymphoma 11A, a transcriptional repressor, is highly expressed in triple negative breast cancer. The in vitro studies and animal models provide initial evidence suggesting that the knockdown of B-cell lymphoma 11A has a therapeutic eff ect on breast cancer. Defining the regulators driving the high expression of B-cell lymphoma 11A is important to understand its cancer-related functions. Among these regulators, transcription factors and microRNAs are critical for gene expression and associated with expression perturbations. Firstly, weidentifi ed the transcription factors that potentially interact with B-cell lymphoma 11A promoter. Based on bioinformatics prediction and multiple Omics datasets, two upregulated transcriptional activators Zinc Finger BED-Type Containing 4 and E2F Transcription Factor 1 in triple negative breast cancer were found to have seven sites within B-cell lymphoma 11A promoter. Secondly, we aimed to determine a putative set of microRNA that can mediate the post-transcriptional repression of B-cell lymphoma 11A. miR-513a-5p, miR-139-5p, miR-1179, miR-140-5p, and miR-542-3p, harboring at least one site of interaction with B-cell lymphoma 11A 3 untranslated region, were found inhibited in triple negative breast cancer. Taken together, the combinatorial regulation by transcription factors and microRNAs provide valuable information for further investigation on controlling the expression level of B-cell lymphoma 11A in triple negative breast cancer.

Authors: Nashawi Fatimah A. , Abdullah Hani Y. , Khalifa Nahlaa A. , Alzahrani Ibrahim A. , Al-Ghamdi Ahmed A.
Published: November 2019

To evaluate the antibacterial eff ects of three types of Saudi honey (Feghra, Sider and Natural honey) alone and mixed with ginger or lemon in comparison to Manuka honey as a potential natural antibacterial agent. Saudi honeys were evaluated against five types of bacterial strains; Klebsiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Haemophilus influenzae and Streptococcus pneumoniae. Chocolate agars were prepared first with different concentrations of each type of honey, and then with specific concentrations either of ginger or lemon added to honey. Bacterial species were inoculated on each agar and incubated at 37oC in a CO2 incubator overnight. Significant differences were found between diff erent types of honey and different concentrations of the same honey on bacterial growth. There are no significant differences and synergistic effects when adding ginger to diff erent honey types. Addition of lemon show significant differences and good synergistic effects against all tested bacterial species except Klebsiella pneumoniae and Staphylococcus aureus at 15 and 20% honey concentration. In conclusion, antibacterial effects of different types of honey are type and concentration dependent. Adding lemon to the different types of honey changes the pH and acidity and increases the honey’s antibacterial effect.
Heparin-Induced Thrombocytopenia Complicating Thrombotic Thrombocytopenic Purpura
Authors: Zaher Galila F. , Badawi Maha A.
Published: November 2019

Since the introduction of therapeutic plasma exchange for the management of thrombotic thrombocytopenic purpura, the prognosis of this disease improved signifi cantly. Some patients suffer from refractory disease and adjunctive therapy needs to be considered. In addition, alternative explanations for thrombocytopenia may bepresent. In this report we discuss a patient who presented with typical fi ndings of thrombotic thrombocytopenic purpura and responded initially to therapeutic plasma exchange and steroids. Shortlyafterwards, his platelet count deteriorated and he was found to have acute pulmonary embolism. Prior to the pulmonary embolism, the patient had received venous thromboembolism prophylaxis in the form of low molecular weight heparin and had a history of previous exposure to unfractionated heparin. Testing for heparin-induced thrombocytopenia antibodies was positive and the patient was started on an alternative anticoagulant. Despite these early interventions the patient did not survive. It is essential that physicians be aware of such possible associations to request appropriate investigations and start appropriate management, accordingly.
Allergy to Insulin Analogs in Gestational Diabetes
Authors: Ghamri Kholoud A.
Published: November 2019

Since human recombinant insulin preparations has been introduced in medicine, allergies to insulin have rarely been reported, especially in pregnant women, who experience immune system alterations that are due to physiologic changes that occur during pregnancy. We describe a 41-year old woman who developed gestational diabetes during the second trimester and was initially treated with insulin aspart and detemir. She complained of itching, redness and a burning sensation at insulin injection sites a few weeks after administration of both insulin types. This warranted cessation of her current insulin regimen and switching to Humulin R and Humulin N due to the unavailability of insulin lispro in the hospital. In addition, patient couldn’t afford buying it from outside the hospital. Her serum glucose was well controlled on this insulin regimen, and no allergic reaction was reported by the patient. Insulin allergy is an unusual finding in pregnancy, which can be managed by switching treatment regimens.

Improved Wait Times from Abnormal Diagnostic Imaging to Biopsy of Suspicious Breast Lesions at King Abdulaziz University Hospital
Authors: Ashkar Laila K.
Published: November 2019

Timely coordinated breast biopsies following abnormal diagnostic breast imaging reduces patient anxiety and may optimize breast cancer prognosis. Two different pathways have been used in the breast unit at the Radiology Department of King Abdulaziz University Hospital. Before September 2009, all patients who had abnormal breast imaging were sent back to their referring physician, who would then request the necessary biopsy. In September 2009, we proposed the shortened pathway; and coordinated the necessary biopsy directly at our unit, instead of sending the patients back to their physician. This has saved them many weeks of agony and confusion navigating through the medical system to arrange appointments for surgical consultation and radiological biopsy. This study aimed to assess the wait time from abnormal breast imaging to the time of the biopsy. A retrospective study included an analysis of 51 consecutive breast biopsies performed before 2009, compared to 51 biopsy patients after implementing the improved pathway in 2009. It concluded that the expedited pathway reduced the wait time from 42 to 14 days until final diagnosis. To ensure that targets for timeliness are realized, this improved and efficient pathway of care was adapted permanently and has been ongoing since then.
Circumareolar Versus Circumvertical Mastopexy with Augmentation
Authors: Awan Basim A.
Published: November 2019

The main aim of augmentation mastopexy is to obtain harmonic relation between breast volumes, shape and scar. There are several variations of the modified breast lift, including circumareolar and circumvertical techniques, each of which has its own unique characteristics and approaches. The aim of this retrospective study was to evaluate and compare the uses of circumareolar (n = 55, 27.20%) versus circumvertical (n = 147, 72.80%) augmentation-mastopexy in 202 women over a 10 years period. Results showed that 28 patients (50.90%) with circumareolar augmentation-mastopexy need revised surgery due to undesired breast shape (n = 24, 43.60%), stretched areola (n = 17, 30.90%) and bad scar (n =9, 16.40%); while 32 patients (22.40%) with circumvertical augmentation-mastopexy need revised surgery due to secondary ptosis (n = 29, 19.70%), large areola (n =3, 2.00%) and unpleasant vertical scar (n = 13, 8.80%). The present study concluded that circumareolar augmentation-mastopexy procedure showed less satisfactory results with undesirable breast and areola shape and bad scars, while circumvertical augmentation-mastopexy gives better results for the areola and breast shape with less potential revision.

City in Reverse: Paintings on Plastics
Authors: Vermeren Karen
Published: November 2019

De kalksteenmijn Rüdersdorf vlakbij Berlijn voorziet de hoofdstad van steen die omgezet wordt in mortel, cement en beton. Het geologisch landschap vormt zo de basis van de stad waarbij de grondstoffen worden opgenomen in cartografieën. De stenen passeren de afbakeningen van de site en verplaatsen zich via constructies, ladders en netten om zich te nestelen in het nieuwe grid van de stad. In haar onderzoek stelt schilder Karen Vermeren de traditionele opvattingen van landschapsschilderkunst ter discussie. Haar werk zoekt naar nieuwe representaties van het geologisch landschap in tweedimensionaal in-situ installaties.

Abstract. The molecular compositions of polar organic compounds (POCs) in
particles emitted from various vessels and excavators were characterized
using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR
MS), and possible molecular structures of POCs were proposed. POCs were
extracted with purified water and sorted by elemental composition into three
groups: CHO, CHON, and S-containing compounds (CHONS and CHOS). The results
show the following. (i) CHO (accounting for 49 % of total POCs in terms of peak
response) was the most abundant group for all tested off-road engines,
followed by CHON (33 %) and CHOS (35 %) for diesel and HFO (heavy-fuel-oil)-fueled off-road engines. (ii) The abundance and
structure of the CHON group in water extracts were different in terms of
engine type and load. The relative peak response of CHON was the highest for
excavator emissions in working mode, compared to the idling and moving
modes. Furthermore, dinitrophenol and methyl dinitrophenol were potentially
the most abundant emission species for high-rated speed excavators, while
nitronaphthol and methyl nitronaphthol were more important for low-rated
speed vessels. (iii) The composition and structure of the S-containing
compounds were directly influenced by fuel oil characteristics (sulfur
content and aromatic ring), with more condensed aromatic rings in the
S-containing compounds proposed in HFO-fueled vessel emissions. More
abundant aliphatic chains were inferred in diesel equipment emissions.
Overall, higher fractions of condensed hydrocarbons and aromatic rings in
POCs emitted from vessels using HFO cause strong optical absorption
capacity. Different structures in POCs could provide a direction for
qualitative and quantitative analysis of organic compounds as tracers to
distinguish these emissions from diesel or HFO-fueled off-road engines.

Abstract. Over the last decades a suite of inorganic proxies based on foraminiferal calcite have been developed, of which some are now widely used for paleoenvironmental reconstructions. Studies of foraminiferal shell chemistry have largely focused on cations and oxyanions, while much less is known about the incorporation of anions. The halogens fluoride and chloride are conservative in the ocean, which makes them candidates for reconstructing paleoceanographic parameters. However, their potential as a paleoproxy has hardly been explored, and fundamental insight in their incorporation is required. Here we used nano-scale secondary ion mass spectrometry (NanoSIMS) to investigate, for the first time, the distribution of Cl and F within shell walls of four benthic species of foraminifera. In the rotaliid species Ammonia tepida and Amphistegina lessonii Cl and F were highly heterogeneous and correlated within the shell walls, forming bands that were co-located with the banded distribution of phosphorus. In the miliolid species Sorites marginalis and Archaias angulatus the distribution of Cl and F was much more homogeneous without discernible bands. In these species Cl and P were correlated, whereas no correlation was observed between Cl and F or between F and P. Additionally, their F content was about an order of magnitude higher than in the rotaliid species. The high variance in the Cl and F content in the studied foraminifera could not be attributed to environmental parameters. Based on these findings we suggest that in the rotaliid species Cl and F are predominately associated with organic linings. We further propose that in the miliolid species Cl may be incorporated as a solid solution of chlorapatite or associated with organic molecules in the calcite. The high F content together with the lack of correlation between Cl and F or P in the miliolid foraminifera suggests a fundamentally different incorporation mechanism. Overall, our data clearly show that the calcification pathway employed by the studied foraminifera governs the incorporation and distribution of Cl, F, P and other elements in their calcite shells.
Enhancing the operational value of snowpack models with visualization design principles

Published: November 2019

Abstract. Forecasting snow avalanches requires a reliable stream of field observations, which are often difficult and expensive to collect. Despite the increasing capability of simulating snowpack conditions with physical models, models have seen limited adoption by avalanche forecasters. Feedback from forecasters suggest model data is presented in ways that are difficult to interpret and irrelevant to operational needs. We apply a visualization design framework to enhance the value of snowpack models to avalanche forecasters. An established risk-based workflow for avalanche forecasting is used to define the ways forecasters solve problems with snowpack data. We address common forecasting tasks such as identifying snowpack features related to avalanche problems, summarizing snowpack features within a forecast area, and locating problems in terrain. Examples of visualizations that support these tasks are presented and follow established perceptual and cognitive principles from the field of information visualization. Interactive designs play a critical role in understanding these complex datasets and are well suited for forecasting workflows. Preliminary feedback suggests these design principles produce visualizations that are more relevant and interpretable for avalanche forecasters, but additional operational testing is needed to evaluate their effectiveness. By addressing issues with interpretability and relevance, this work sets the stage for implementing snowpack models into workstations where forecasters can test their operational value and learn their capabilities and deficiencies.
Articulación de lógicas y modos de sociabilidad económicos: un análisis a partir de cuatro experiencias de Economía social y solidaria en España
Authors: Carrero Gros Gaël , Sanz Abad Jesús
Published: November 2019

En las últimas décadas ha aumentado el interés por la denominada Economía Social y Solidaria (ESS), tanto como paradigma como sector de la economía. Sin embargo, en los trabajos académicos realizados se observa una brecha entre la caracterización teórica que se desarrolla en torno al concepto de la ESS y sus principios, y la escasez de estudios de caso realizados, apoyados en una recogida de datos empírica que permita comprender cómo se consiguen –o no– materializar estos principios en la práctica del día a día. En este artículo proponemos problematizar esta cuestión a partir de una aproximación etnográfica a cuatro iniciativas económicas de distintos sectores que se autoidentifican como “prácticas de ESS”. Estos casos nos permiten mostrar una diversidad de casuísticas que ponen de relieve la diversidad de lógicas y modos de sociabilidad que se articulan bajo estas prácticas, y finalmente, el escenario de pluralidad económica que se refuerza y se crea en torno a la ESS.

Authors: Abdulrahman AlQahtani Najla
Published: November 2019

Academic lectures are one of the areas that university students encounter most often. Comprehending these lectures is crucial for English language learners. In order to bring about more effective and inclusive learning experience, an understanding to the difficulties facing the English department students should be provided. This study aims at acquiring an in-depth understanding of the difficulties and challenges that female students in the English department at Prince Sattam Bin Abdelaziz University face, from their own unique perspective, while listening to English lectures. Participants were undergraduate female students in the English department at Prince Sattam Bin Abdelaziz University (n= 112) who randomly responded to a twenty five multiple choice online questionnaire and one open-ended question. The study examined two types of difficulties; linguistic and non-linguistic. Those difficulties were categorised according to two variables; the students’ level and GPA. A mixed-method research design was adopted and a quantitative and qualitative data collection methods were employed during the first semester of the academic year 1440-1441. Findings indicated that students’ difficulties in relation to the linguistic factors were at a high level whereas difficulties related to the non-linguistic factors were at a medium level. In light of the study findings, recommendations and implications were presented.

Descobrir o gosto musical de uma pessoa tem uma aplicação óbvia nos mecanismos de recomendaçãousados pelos provedores de serviços de música on-line. Estamos interessados em uma aplicação menosóbvia, relacionada ao ambiente de trabalho de um desenvolvedor de software. Neste trabalho em particular,comparamos dois algoritmos usados em mineração de dados como classificadores. O objetivo é compararSupport Vector Machine (SVM) e k-Nearest Neighbor (k-NN) como preditores do gosto musical de um usuário.Para executar o experimento, usamos um banco de dados de músicas que foram previamente classificadascom um rótulo indicando se o usuário gosta ou não de cada música. O banco de dados inclui um conjuntode características das músicas, cada classificador usa as mesmas combinações de características no processode aprendizado e, em seguida, classifica novas instâncias de músicas de acordo com o gosto previsto parao usuário. Este estudo inicial indicou que o SVM é um melhor preditor do que o k-NN para este contextoparticular. Em investigações futuras, pretendemos avaliar o usuário em um ambiente síncrono, nossa hipóteseé que pode ser possível entender mais do que o cenário de gosto / não gosto e expandir para o que o usuárioquer ouvir em um momento específico, com o qual planejamos capturar o estado emocional atual do usuário.Eventualmente, queremos correlacionar o estado emocional de um desenvolvedor de software com a propensãoa defeitos do código escrito.
