Travis Wilkerson: hacia una arqueología de la violencia
Authors: Martínez Bonilla Mariana 
Published: February 2020

El objetivo principal de este texto es reflexionar en torno a las maneras a través de las cuales el cineasta norteamericano Travis Wilkerson (1969) cuestiona, a partir de la problematización de la historia de la violencia racial en el sur de los Estados Unidos durante el siglo XX, el presente violento de dicha nación. A través de algunos conceptos como política, archivo y montaje se analizará el ensayo fílmico Did You Wonder Who Fired the Gun? (2017), en el cual, a través de la experimentación formal y narrativa, así como del trabajo de resignificación del material audiovisual, proveniente de diversas fuentes y archivos, el cineasta interpela directamente a la memoria del siglo pasado y logra conformar un particular discurso estético que reposa en la posibilidad de una historia alternativa.

Compósitos possuem propriedades como baixo peso e elevada resistência, o que faz com que sejam cada vez mais estudados para utilização em peças da indústria aeronáutica. Entretanto, devido as condições em que são expostas as aeronaves quando em voo, é necessário uma avaliação de propriedades dos materiais para essa utilização. Uma das formas para esta avaliação é submeter os materiais a ensaios de condicionamento ambiental para analisar a resistência destes quando expostos a intempéries. Uma das limitações na utilização de compósitos industrialmente é o uso de processos de união adequados, sendo os mais comum união adesiva, fusão e rebitagem. Por possuir vantagens como melhor qualidade da junta e menor custo o processo de união por fusão se destaca dos demais. Neste sentido este trabalho visa avaliar a resistência mecânica de juntas soldadas por oxiacetileno de material compósito PEI/fibra de carbono quando submetidos a ensaios de condicionamento ambiental higrotérmico e ultravioleta.

Abstract
WISEA J080822.18–644357.3, an M star in the Carina association, exhibits extreme infrared excess and accretion activity at an age greater than the expected accretion disk lifetime. We consider J0808 as the prototypical example of a class of M star accretion disks at ages ≳20 Myr, which we call “Peter Pan” disks, because they apparently refuse to grow up. We present four new Peter Pan disk candidates identified via the Disk Detective citizen science project, coupled with Gaia astrometry. We find that WISEA J044634.16–262756.1 and WISEA J094900.65–713803.1 both exhibit significant infrared excess after accounting for nearby stars within the Two Micron All Sky Survey (2MASS) beams. The J0446 system has >95% likelihood of Columba membership. The J0949 system shows >95% likelihood of Carina membership. We present new Gemini Multi-Object Spectrograph optical spectra of all four objects, showing possible accretion signatures on all four stars. We present ground-based and TESS light curves of J0808 and 2MASS J0501–4337, including a large flare and aperiodic dipping activity on J0808, and strong periodicity on J0501. We find Paβ and Brγ emission indicating ongoing accretion in near-IR spectroscopy of J0808. Using observed characteristics of these systems, we discuss mechanisms that lead to accretion disks at ages ≳20 Myr, and find that these objects most plausibly represent long-lived CO-poor primordial disks, or “hybrid” disks, exhibiting both debris and primordial-disk features. The question remains: why have gas-rich disks persisted so long around these particular stars?
Excitation Sources of Oscillations in Solar Coronal Loops: A Multi-wavelength Analysis
Authors: Conde C. Sandra M. , Jain Rekha , Jatenco-Pereira Vera 
Published: February 2020

Abstract
An investigation into the excitation sources of oscillations detected in a coronal loop structure is carried out using the images obtained with Interface Region Imaging Spectrometer (IRIS) and the Atmospheric Imaging Assembly (AIA) instrument on board the Solar Dynamics Observatory (SDO). A loop structure in the active region AR 11967 on 2014 January 28, oscillating in the vicinity of a strong eruption and an M3.6 class flare site, is clearly noticeable in SDO/AIA 171 Å images. We study in detail, the oscillations with detected periods between 4 and 13 minutes and their connection in IRIS SJI 1330 Å and SDO/AIA 1700 Å images; both of these wavelengths sample the lower parts of the solar atmosphere. The simultaneous presence of many oscillations in the region of interest in all three wavelength passbands suggest that these oscillations were excited in the lower-chromosphere–photosphere plasma connected to the loop structure and then propagated at higher heights. We further investigate the Doppler velocity measurements from the spectrograph snapshots in IRIS C ii 1336 Å, Si iv 1403 Å and Mg ii k 2796 Å. These show signatures of upflows in the vicinity of the loop structure’s endpoints estimated from 171 Å images. We suggest that some of the oscillations observed in AIA 171 Å have been triggered by plasma ejections and perturbations seen in the lower layers of the solar atmosphere. Based on the estimated phase speeds, the oscillations are likely to be slow magnetoacoustic in nature.
Retractions of research papers by authors from the Arab region (1998-2018)
Authors: Aldeen AlRyalat Saif , Azzam Muayad , Massad Abdallah , Alqatawneh Dana 
Published: February 2020

Objective: To provide an overview of retractions of research papers contributed by authors from the Arab region.
Method: Papers in which the first author was affiliated to an Arabian country were selected from the Retraction Watch database covering the period 1 January 1998 to 31 December 2018. The retrieved records were divided into nine categories based on the reasons for retraction.
Results: The search yielded 322 retractions, and the most frequent reason for retraction was plagiarism (34.5%). The median time from publication to retraction was 14 (25%-75% percentile 5-30) months. The number of papers retracted each year as well as the number of papers published in a given year but subsequently retracted increased steadily over the 21 years. The proportion of retracted papers to the total number of published papers (0.17%) was higher than the global proportion and was the highest for Algeria (1%) and the lowest for Lebanon (0.03%). Of the countries within the Arab region, 12 out of 14 countries showed either plagiarism or duplication as the most common reason for retraction; however, the countries differed in terms of the number of retractions and the time from publishing to retraction.
Conclusion: Plagiarism was the most common cause of retraction in the Arab countries. The increase in the number of papers retracted each year was probably because searches now extend farther in the past, whereas the increase in the number of papers published in a given year but subsequently retracted can be attributed to the overall increase in the number of papers published.
The Production of the New Man Within the PKK
Authors: Grojean Olivier 
Published: February 2020

Les chercheurs ont surtout analysé les théories de l’« Homme nouveau » en tant que composante idéologique des systèmes totalitaires. Fondée sur l’étude du Parti des Travailleurs du Kurdistan (PKK), la plus importante organisation du mouvement kurde de Turquie, cet article dépasse le cadre des idéologies d’Etat pour analyser les relations entre théories et pratiques, et pour évaluer les effets concrets de la doctrine de l’Homme nouveau sur les activistes du PKK. Cet article examine donc les discours politiques au sein du PKK afin de comprendre comment, au delà du marxisme et du nationalisme, s’est institutionnalisée une construction spécifique de l’Homme nouveau au sein de l’organisation. A cette fin, le parti a utilisé un certain nombre de dispositifs disciplinaires : l’autocritique a notamment joué un rôle très important dans toutes les branches de l’organisation. Evaluer l’efficacité de ces dispositifs est difficile, mais l’article suggère que l’étude des trajectoires biographiques des individus engagés permet de mieux comprendre pourquoi et surtout comment certains militants ont pu (ou pas) se conformer aux idéaux développés par le PKK.

Introduction: Accurate estimation of the body weight (BW) increases the safety and effectiveness of medical and pharmacological interventions. However, various situations make it difficult or even impossible to obtain a patient’s body weight. In those instances, the need for an alternate method of weight determination arises. Consequently, several studies have proposed obtaining BW through prediction formulas based on various anthropometric variables. Objective: Despite its’ potential practical utility, little is known concerning the relationship between head circumference (HC) and BW among the adult Sri Lankans. The goal of this study was to propose population and gender specific regression formula for BW estimation using HC. Material & method: Body weight and HC was recorded in a total of 156 cadavers: male: n=74; female: n=82. Subjects with any craniofacial deformities or neurological disorders were excluded from the study. Results: The mean BW (kg) (male: 53.78 ± 14.14; female: 47.91 ± 7.26) and HC (cm) (male: 54.09 ± 3.28; female: 52.88 ± 2.83) of the study subjects were found to be significantly different (P< 0.01) between the genders. Correlation coefficient between the BW and HC was statistically significant and positive in both males (0.745) and females (0.365) indicating a strong relationship between the two parameters. Linear regression formulae for the prediction of BW using the HC were derived as follows: male: 31.27 + 1.57 (HC); female: 53.09 + 1.91 (HC). Conclusion: Weight prediction equations that require a measuring tape as the only tool provides a practical alternative for the weight estimation of patients who are unable to walk due to various reasons. The use of anthropometric measurement such as HC is a simple, cost effective, non-invasive and objective method for BW prediction. Accurate prediction of a patient’s weight will in turn, reduce potential drug dosing errors that may occur when weight is estimated only by visual observation in emergency situations. Complementary studies are necessary to evaluate the applicability of these equations in other age groups too.

Introduction: Road traffic accidents involving motor cycles often results in severe morbidity and mortality. There has been a significant increase in incidences of motorcycle accidents in Sri Lanka in the recent past. This study was conducted to understand the different factors related to the motor cycles, users and the roads which determine the injury patterns on victims, who were presented to the Teaching Hospital, Karapitiya, Sri Lanka. Methods: This prospective analytical study was carried out among the motor cycle users admitted during the six months from January 2015. Results: A total of 272 patients (233 males) ranging in age from 6 months to 73 years (mean = 30 years) were included. Out of all patients 194 (71.3%) were riders. About 50.7% of the incidents happened during the daytime. Majority of patients had ridden classical motor cycles (66.2%) and 56.6% of all bicycles had a crash bar. About 9.9% of the victims were wearing full face helmets whereas 11.4% were without helmets. It is recorded that 51.5% of the incidents occurred in urban areas and 91.2% of accidents were on tarred roads. Majority incidences (82.4%) happened when it was not raining. Abrasions were the commonest (69.5%) injury and 47.1% of patients had injuries which fell in to Grievous Hurt Category according to the Penal Code of Sri Lanka. Wearing helmets is a protective factor from head injuries (p=0.020). Full face helmets provided protection from facial injuries than partial coverage helmets (p=0.037). Conclusions: Motor cycle users sustain different types of injuries and majority was Grievous Hurt category. Wearing helmets is a protective factor from head injuries andfull face helmets provided protection from facial injuries than normal helmets.

Abstract
Although the consequences of splenectomy are well understood in mice, much less is known about the immunologic changes that occur following splenectomy in humans. We sought to characterize the circulating immune cell populations of patients before and after elective splenectomy to determine if these changes are related to postsplenectomy survival outcomes. Retrospective clinical information was collected from 95 patients undergoing elective splenectomy compared with 91 patients undergoing pancreaticoduodenectomy (Whipple procedure). We further analyzed peripheral blood from five patients in the splenectomy group, collected before and after surgery, using single-cell cytometry by time-of-flight mass spectrometry. We compared pre- and postsplenectomy data to characterize both the major and minor immune cell populations in significantly greater detail. Compared with patients undergoing a Whipple procedure, splenectomized patients had significant and long-lasting elevated counts of lymphocytes, monocytes, and basophils. Cytometry by time-of-flight mass spectroscopy analysis demonstrated that the elevated lymphocytes primarily consisted of naive CD4+ T cells and a population of activated CD25+CD56+CD4+ T cells, whereas the elevated monocyte counts were mainly mature, activated monocytes. We also observed a significant increase in the expression of the chemokine receptors CCR6 and CCR4 on several cellular populations. Taken together, these data indicate that significant immunological changes take place following splenectomy. Whereas other groups have compared splenectomized patients to healthy controls, this study compared patients undergoing elective splenectomy to those undergoing a similar major abdominal surgery. Overall, we found that splenectomy results in significant long-lasting changes in circulating immune cell populations and function.
Shakespeare in the Theatre: Yukio Ninagawa
Authors: Hanratty Conor 
Published: February 2020

Yukio Ninagawa (1935–2016) was Japan's foremost director of Shakespeare whose productions were acclaimed around the world. His work was lauded for its spectacular imagery, its inventive use of Japanese iconography and its striking fusion of Eastern and Western theatre traditions.
Over a career spanning six decades, Ninagawa directed 31 of Shakespeare's plays, many of them, including Hamlet, on multiple occasions. His landmark productions of Macbeth, The Tempest, Hamlet, Pericles, Twelfth Night and Cymbeline became seminal events in world Shakespeare production during the last 30 years.
This is the first English-language book dedicated exclusively to his work. Featuring an overview of the extraordinary number of Shakespeare plays he directed, this study considers both his Shakespearean work and his productions of Greek tragedy, including Oedipus The King and his landmark production of Medea in 1978. His productions of Romeo and Juliet, King Lear, Macbeth and the eight productions of Hamlet which he directed all receive close attention. The volume closes with a detailed analysis of the Sai-no-Kuni Shakespeare Series - in which he set out to stage all of Shakespeare’s plays in his hometown of Saitama, north of Tokyo. Written by Conor Hanratty, who studied with Ninagawa for over a year, it offers a unique and unprecedented glimpse into the work and approach of one of the world’s great theatre directors.
Changes in the future summer Mediterranean climate: contribution of teleconnections and local factors
Authors: Barcikowska Monika J. , Kapnick Sarah B. , Krishnamurty Lakshmi , Russo Simone , Cherchi Annalisa , Folland Chris K. 
Published: February 2020

Abstract. This study analyzes future climate for the Mediterranean region projected
with the high-resolution coupled CM2.5 model, which incorporates a new and
improved land model (LM3). The simulated climate changes suggest pronounced
warming and drying over most of the region. However, the changes are
distinctly smaller than those of the CMIP5 multi-model ensemble. In
addition, the changes over much of southeast and central Europe indicate
very modest warming compared to the CMIP5 projections and also a tendency toward wetter conditions. These differences indicate a possible role of factors such as land surface–atmospheric interactions in these regions. Our analysis also highlights the importance of correctly projecting the magnitude of changes in the summer North Atlantic Oscillation, which has the capacity to partly offset anthropogenic warming and drying over the western and central Mediterranean. Nevertheless, the projections suggest a decreasing influence of local atmospheric dynamics and teleconnections in maintaining the regional temperature and precipitation balance, in particular over arid regions like the eastern and southern Mediterranean, which show a local maximum of warming and drying. The intensification of the heat low in these regions rather suggests an increasing influence of warming land surface on the local surface atmospheric circulation and progressing desertification.
