A Fire Hazard Assessment Using Sentinel Imagery; A Case Study Over Gippsland Australia
Authors: Raut Sanjeev Kumar , Nhemaphuki David , Aryal Rebanta , Lakandri Prakash
Published: July 2020

Accurate and the efficient rapid mapping of the fire-damaged areas are the most fundamental things for any places to retain from environmental loss. To support the fire management, make definite strategy and planning, and restore the vegetation, it is important to detect the area before and after the fire damages. Under climate change conditions, heat and drought may trigger tough fire regimes in terms of number and dimension of fires. To deliver the rapid information of the area damaged by the fires, Burned Area Index (BAI), Normalized Burned Ratio (NBR) and their versions are applied to map burned areas from high-resolution optical satellite data. The new MSI sensor aboard Sentinel-2 satellites records the more spectral information in the red edge spectral region making it more convenient to the development of new indices for the burned area mapping. Recently, Australia had confronted a devastating bushfire recorded in the history of the nation. In this project, NBR deployed to detect burned areas at around 10m-20m spatial resolution based on pre and post-fire Sentinel-2 images. A dNBR (differentiated Normalized Burned Ratio) was calculated while burn severity was mapped as purposed by United States Geological Survey (USGS). It observed that more than half of the East Gippsland region i.e. about 53% of the area affected by the wildfire while 38% remained unburned and 8.4% showed the regrowth.

La revolución inhallable
Authors: Peña Carlos
Published: July 2020

Este artículo explora algunas de las causas que subyacen a los sucesos de octubre en Chile. Sugiere que en el debate que siguió inmediatamente a esos hechos se puso más énfasis en la adscripción de significados normativos que en el examen de los factores que los hicieron posible. Una revisión de la literatura ayudaría a indagar en estos últimos. Esa literatura —desde la sociología clásica al examen de los nuevos movimientos sociales a partir de los años ochenta— mostraría que, en términos generales, las sociedades que experimentan rápidos procesos de modernización configuran una inconsistencia entre la racionalización técnica indispensable para promover el bienestar con la subjetivación que inunda el mundo de la vida. Ello explicaría que la protesta no sea solo reivindicativa o ideológica, y en cambio se exprese con medios altamente emotivos y escénicos, que semejan un esfuerzo por configurar la gramática de las formas de vida. Esto dibuja una condición ambivalente en la sociedad chilena que plantea un particular desafío a los ideales normativos que promueve la política.

Por medio del uso de estadísticas de comercio y entrevistas clave, trazamos el desarrollo del comercio entre Chile y la UE para los productos agroalimentarios, tanto en términos absolutos como relativos, desde la entrada en vigencia del Acuerdo de Asociación entre la UE y Chile en 2003. Concentrándonos en los principales impulsores de este desarrollo comercial, en este artículo se identifican nuevas oportunidades de comercio que, posiblemente, podrían acompañar la modernización del Acuerdo de Asociación UE-Chile.
Analysis of European interregional cooperation under Interreg programmes. The case of Spain
Authors: Esparza Masana Ricard
Published: July 2020

The present article provides a detailed overview regarding the position of Spain and its Autonomous Communities in the European Territorial Cooperation (Interreg) programmes where the whole country (or some regions) are eligible. This analysis compares the presence (in terms of participation in projects funded by these programmes) of Spain, focusing on three main variables: the regional scope, that is the relative presence of each Autonomous Community, the thematic scope, in terms of the different thematic axes of the programme, and in terms of the institutional scope, in terms of the typology of participating institutions. To perform this analysis, a brand new data base has been generated, aggregating and treating data from eight different sources linked to the four programmes analysed: Interregs Europe, Atlantic, Mediterranean, and South West. Our study aims at providing a sound overview and relevant conclusions that can support, besides the academic approach, the decision-making process towards the definition of the next Interreg programming period 2021-2027, considering Spain as a key example.

We present the discoveries of WISEA J041451.67−585456.7 and WISEA J181006.18−101000.5, two low-temperature (1200–1400 K), high proper motion T-type subdwarfs. Both objects were discovered via their high proper motion (>0.″5 yr−1); WISEA J181006.18−101000.5 as part of the NEOWISE proper motion survey and WISEA J041451.67−585456.7 as part of the citizen science project Backyard Worlds; Planet 9. We have confirmed both as brown dwarfs with follow-up near-infrared spectroscopy. Their spectra and near-infrared colors are unique among known brown dwarfs, with some colors consistent with L-type brown dwarfs and other colors resembling those of the latest-type T dwarfs. While no forward model consistently reproduces the features seen in their near-infrared spectra, the closest matches suggest very low metallicities ([Fe/H]

WISEA J041451.67−585456.7 and WISEA J181006.18−101000.5 are found to be part of a small population of objects that occupy the “substellar transition zone,” and have the lowest masses and effective temperatures of all objects in this group.

Our local thermodynamic equilibrium (LTE) and non-LTE models indicate that the enhanced line ratios (or C i enhancement) are due to an elevated C0/CO abundance ratio (∼3–10) and temperature (∼100–500 K) around the AGN as compared to the SB ring (abundance ratio ∼1, temperature ≲100 K), which accords with the picture of the X-ray-dominated region. Based on dynamical modelings, we also provide CO(1–0)-to- and [C i](3

The Influence of Asymmetrical Distribution of Hemispheric Sunspot Areas on Some Solar Parameters’ Periodicities during the Period 1945–2017: Wavelet Analysis
Authors: El-Borie M. A. , El-Taher A. M. , Thabet A. A. , Ibrahim S. F. , Aly N. S. , Bishara A. A.
Published: July 2020

Monthly data of some solar parameters (the solar radio flux F10.7, the plage area PA, the coronal index CI, the solar mean magnetic field 
B
, and the solar flare index SFI) during the period 1945–2017 have been classified into two groups (northern and southern) based on the distribution of the monthly averages of the hemispheric sunspot areas (SSAs). This has been done to investigate the symmetry and/or asymmetry in periodicities between the hemispheric groups for these parameters by utilizing the Morlet wavelet technique. For each of the considered parameters except 
B
, it is observed that the most dominant and significant period (above the 95% confidence level) in both the wavelet spectra (WPS and GWS) for both hemispheric groups is the solar activity cycle at 10.7 yr during the entire time interval. The power values for other periods appeared to be quite small relative to that of the 10.7 yr period, and of less significance (below the 95% confidence level). For 
B
, the most remarkable sign is the disappearance of the prominent peak of the solar activity cycle. The Hale cycle is clearly seen in both hemispheric groups of 
B
, with a slight shift in time between the two hemispheric groups, and it increased through the entire considered duration. Periodicities of 10.7, 3.5, 1.5, and 0.8 yr have been observed in the northern hemispheric group of the parameters SSAs, F10.7, PA, CI, and SFI, indicating a possible correlation between them. For the southern hemispheric group, however, periodicities of 10.7, 5.4, and 0.8 yr have been revealed for the parameters F10.7, PA, and CI.
Reconstructing the Coronal Magnetic Field: The Role of Cross-field Currents in Solution Uniqueness
Authors: Mathews Nat H. , Flyer Natasha , Gibson Sarah E.
Published: July 2020

We present a new 3D magnetohydrostatic (MHS) direct elliptic solver for extrapolating the coronal magnetic field from photospheric boundary conditions in a manner consistent with an assumed plasma distribution. We use it to study the uniqueness of the reconstructed magnetic field as a function of how significant the plasma forcing is on the force balance of the magnetic field. To this end, we consider an analytic MHS model as ground truth. The model uses two free parameters to decompose the current into two parts: a magnetic-field-aligned component and a cross-field component. We perform a comprehensive study of the 2D parameter space to understand under what conditions the ground truth can be reproduced uniquely. We find that current oriented perpendicular to the magnetic field has a smaller solution space than the same amount of current oriented parallel to the magnetic field, and so MHS regimes with larger proportions of plasma-related forcing may be a promising avenue toward finding unique magnetic field reconstructions.
Properties of the KISS Green Pea Galaxies
Authors: Brunker Samantha W. , Salzer John J. , Janowiecki Steven , Finn Rose A. , Helou George
Published: July 2020

Green peas (GPs) are a class of extreme star-forming galaxies (SFGs) at intermediate redshifts, originally discovered via color selection using multifilter, wide-field survey imaging data. They are commonly thought of as being analogs of high-redshift Lyα-emitting galaxies. The defining characteristic of GP galaxies is a high-excitation nebular spectrum with very large equivalent width lines, leading to the recognition that GP-like galaxies can also be identified in samples of emission-line galaxies. Here we compare the properties a sample of [O iii]-selected SFGs (z = 0.29–0.41) from the KPNO International Spectroscopic Survey (KISS) with the color-selected GPs. We find that the KISS [O iii]-selected galaxies overlap with the parameter space defined by the color-selected GPs; the two samples appear to be drawn from the same population of objects. We compare the KISS GPs with the full Hα-selected KISS SFG sample (z < 0.1) and find that they are extreme systems. Many appear to be young systems at their observed look-back times (3–4 Gyr), with more than 90% of their rest-frame B-band luminosity coming from the starburst population. We compute the volume density of the KISS red (KISSR) GPs at z = 0.29–0.41 and find that they are extremely rare objects. We do not see galaxies as extreme as the KISSR GPs in the local universe, although we recognize several lower-luminosity systems at z < 0.1.
A Fast-growing Tilt Instability of Detached Circumplanetary Disks
Authors: Martin Rebecca G. , Zhu Zhaohuan , Armitage Philip J.
Published: July 2020

Accretion disks in binary systems can exhibit a tilt instability, arising from the interaction between components of the tidal potential and dissipation. Using a linear analysis, we show that the aspect ratios and outer radii of circumplanetary disks provide favorable conditions for tilt growth. We quantify the growth rate of the instability using particle-based (phantom) and grid-based (athena++) hydrodynamic simulations. For a disk with outer aspect ratio H/r ≃ 0.1, initially moderate tilts double on a timescale of about 15–30 binary orbits. Our results imply that detached circumplanetary disks, whose evolution is not entirely controlled by accretion from the circumstellar disk, may commonly be misaligned to the planetary orbital plane. We discuss implications for planetary spin evolution, and possible interactions between the tilt instability and Kozai–Lidov dynamics.
Les Frères Musulmans et le tempo de l’islam radical : un essai d’interprétation
Authors: Boussel Pierre
Published: July 2020

Au lendemain de l’effondrement des empires ottoman et allemand et en parallèle à l’essort du nationalisme arabe, les Frères musulmans construisent une idéologie transnationale : l’islamisme politique. Le courant se veut une alternative globale de gouvernement et de pilotage de la société aux propositions occidentales. Les Frères Musulmans, dans leurs différentes acceptions nationales, cherchent à imposer un projet politique aux États arabes et à l’Occident fondé sur une lecture radicale du Coran. Cet article s’attache à étudier la dimension temporelle de ce mouvement désormais bien ancré dans l’offre politique.
Quelques propositions sur les vertus et limites de la parole dans la pratique de la médiation
Authors: Garcia Peñafiel Mauricio , Poncelet Margaux
Published: July 2020

La médiation se veut un processus démocratique qui permettrait à chaque partie de participer à la construction d’une issue – si pas d’une solution – pour sortir d’un litige. Son principal outil pour ce faire est la parole. Mais cette prise de parole n’est pas sans mobiliser de nombreux enjeux. Nous explorerons dans cet article quatre limites de la parole que l’on peut rencontrer dans le cadre de la médiation. Tout d’abord, la parole est intimement liée au désir et aux passions humaines, ce qui ne permet pas toujours de la considérer comme le résultat d’un processus raisonné qui ne cherche à communiquer que ce qu’elle énonce stricto sensu. Parler instaure des places entre les interlocuteurs, parfois de manière inconsciente. De là se dégagent des questions quant à la neutralité et l’impartialité du médiateur notamment. Nous poserons ensuite la question de savoir en quoi les valeurs de la médiation peuvent venir contaminer quelque chose du processus de médiation et de la position même du médiateur comme tiers, l’invitant à un processus autoréflexif. La prétention de compréhension empathique ou de rétablissement de la communication, sera également interrogée. Nous suggérons que le malentendu, les méprises entre les parties ne sont pas nécessairement un échec. Parfois la coexistence nécessite une part d’ombre, et le malentendu alors est une réussite. Enfin, nous explorerons les limites liées au désir de reconnaissance. Si parler permet aux humains de se donner une certaine reconnaissance réciproque, ce même désir est source de conflit et parfois érige des obstacles au processus de médiation.
Le cœur du droit. Réflexions sur certains enjeux juridiques, philosophiques et théologiques du « droit de chacun de mener une vie digne d’être vécue »
Authors: Van der Noot Olivier
Published: July 2020

En réponse à un exposé donné le 14 mars 2017 par A. Bailleux sous le titre « Penser le droit dans une société de l’après-croissance », la présente étude propose quelques réflexions sur le « principe de justice » qui sous-tend l’émergence d’une telle société. Dans un premier temps, l’étude se tourne vers la théorie des capabilités développée par Martha Nussbaum pour approfondir l’examen de ce principe – parfois formulé comme un « droit de mener une vie digne d’être vécue » – sur le plan philosophique. Dans un second temps, l’étude, résolument ouverte à la théologie – et à la foi, sans laquelle la théologie est impossible –, examine la mesure dans laquelle une telle théorie peut s’avérer féconde pour penser le droit dans une société de l’après-croissance.
Single-Haptic Dislocation of Retropupillary Iris-Claw Intraocular Lens: Outcomes of Reenclavation
Authors: Kim Min Seok , Park Sang Jun , Joo Kwangsic , Kang Hyun Goo , Kim Min , Woo Se Joon
Published: July 2020

BACKGROUND AND OBJECTIVE:

To report the clinical feature of dislocated retropupillary iris-claw aphakic intraocular lens (IOL) and outcomes of reenclavation.

PATIENTS AND METHODS:

In this multicenter, retrospective case series, 225 eyes of 225 patients underwent retropupillary fixation of iris-claw aphakic IOL and the cases with haptic dislocation were reviewed.

RESULTS:

Single haptic dislocation was observed in 22 of 225 eyes (9.8%) after 89 ± 77 days (range: 5 days to 277 days) postoperatively, and resolution was achieved through reenclavation without any intraoperative complications in all patients. Iris atrophy in 13 eyes (59%) and history of face washing at the time of dislocation in five patients (23%) were noted. Reenclavation did not cause statistically significant change in best-corrected visual acuity (
P
= .315), spherical equivalent (
P
= .660), or endothelial cell count (
P
= .182) compared to those after the primary surgery.

CONCLUSION:

Single-haptic dislocation of retropupillary iris-claw aphakic IOL is not a rare complication and can be safely and effectively corrected by reenclavation.

Tribological Characteristic of Tool Steel Surface Layer Alloyed Using Laser
Authors: Bonek Mirosław , Tillová Eva
Published: July 2020

The article presents the results of research on the impact of laser surface treatment on selected steel properties. The laser treatment consisted of remelting and alloying high speed steel using hard ceramic phase powders. A high-power diode laser was used in the experiment to examine the effect of parameters such as beam power and powder type on the structure and properties of the surface layer. A structural mechanism was observed consisting in obtaining, after laser processing, a super fine crystalline structure and a dendritic structure at the remelting zone. Structural changes have been found to be associated with improved properties such as hardness, microhardness and wear resistance. Steel treated with conventional heat treatment was used as a comparative material.
The Use of Lasers at Various Stages of the Manufacturing Process of Solar Cells Based on Crystalline Silicon
Authors: Musztyfaga-Staszuk Małgorzata , Panek Piotr
Published: July 2020

The purpose of this chapter of the book is to present knowledge on the use of laser technology in silicon photovoltaic cell manufacturing processes. Particular consideration was given to the technique of using a disk laser to cut the edges of silicon wafers together with the recognition of the flow of laser micromachining on the quality of cut edges to obtain their minimal deformation. The second topic described is the method of producing point contacts employing laser radiation between a layer of vaporised aluminium and crystalline silicon using the Nd:YAG laser. The results illustrating the impact of the structure and parameters of point contact for a given laser radiation energy on basic electrical parameters for complete, prototype solar cells are included. The chapter in the book provides an overview of the literature on the above topics and presents selected results of experimental works carried out by the authors. The motive for its publication is the need to present selected results of own research carried out in the Welding Department cooperating for many years with the Institute of Engineering and Biomedical Materials (IMIiB) of the Silesian University of Technology and the Institute of Metallurgy and Materials Engineering (IMIM) of the Polish Academy of Sciences in Cracow.
Structure of Titanium GRADE 1 after Laser Alloying with FeCr Powder
Authors: Wiśniowski Maciej , Tański Tomasz , Snopiński Przemysław
Published: July 2020

Titanium alloys due to their low density and high mechanical properties are a group of materials that are being used willingly nowadays. A promising method of titanium heat treatment is laser surface alloying. Process parameters like laser beam power, its transverse speed, amount of alloying elements and shield gas, have influence on the material. Different chemical composition and morphology can be achieved resulting in a change of properties on the surface of the material. The paper presents the investigation of titanium GRADE 1 processed with iron‐nickel powder using laser alloying. The treatment was performed using a high power diode laser. Different laser beam power values were used.
Design and Selective Laser Melting Manufacturing of TPE Extrusion Die
Authors: Król Mariusz , Musiorski Marek , Pagáč Marek
Published: July 2020

In presented work, extrusion die made by maraging steel used in TPE processing was optimised by means of flow dynamics of the final part. Maraging steel Ni-18 (M300) die were produced by Selective Laser Melting (SLM) using AM125 machine provided by Renishaw. The developed and manufactured extrusion die has not been processed by finishing the process, i.e. grinding, polishing or sandblasting. The tests were carried out using TPE industrial extrusion plant. Moreover, designed extrusion die to decrease weight and save the material; the design was hollow. The presented results indicate that the SLM technique is a promising method for the production in one production process the extrusion dies used in the TPE extrusion process with complex internal walls, with high accuracy, high speed and at low costs and own outlays. Moreover, this technique gives the constructors possibilities to design very complicated shapes of profiles with more than one of the working areas (bubbles) or design co-extrusion dies. Application of SLM technique allows to manufacture air ducts with pipe connectors to fasten an air, hence eliminating from the process expensive and time-consuming electrical discharge machining.

Authors: Thoma Brent , Hall Andrew K. , Clark Kevin , Meshkat Nazanin , Cheung Warren J. , Desaulniers Pierre , ffrench Cheryl , Meiwald Allison , Meyers Christine , Patocka Catherine , Beatty Lorri , Chan Teresa M.
Published: July 2020

Background

In 2018, Canadian postgraduate emergency medicine (EM) programs began implementing a competency-based medical education (CBME) assessment program. Studies evaluating these programs have focused on broad outcomes using data from national bodies and lack data to support program-specific improvement.

Objective

We evaluated the implementation of a CBME assessment program within and across programs to identify successes and opportunities for improvement at the local and national levels.

Methods

Program-level data from the 2018 resident cohort were amalgamated and analyzed. The number of entrustable professional activity (EPA) assessments (overall and for each EPA) and the timing of resident promotion through program stages were compared between programs and to the guidelines provided by the national EM specialty committee. Total EPA observations from each program were correlated with the number of EM and pediatric EM rotations.

Results

Data from 15 of 17 (88%) programs containing 9842 EPA observations from 68 of 77 (88%) EM residents in the 2018 cohort were analyzed. Average numbers of EPAs observed per resident in each program varied from 92.5 to 229.6, correlating with the number of blocks spent on EM and pediatric EM (r = 0.83, P < .001). Relative to the specialty committee's guidelines, residents were promoted later than expected (eg, one-third of residents had a 2-month delay to promotion from the first to second stage) and with fewer EPA observations than suggested.

Conclusions

There was demonstrable variation in EPA-based assessment numbers and promotion timelines between programs and with national guidelines.
Resident Physician Prescribing Variability Demonstrates Need for Antimicrobial Stewardship in Continuity Clinic: A Pilot Study
Authors: Andrews Shannon , Beaudoin Amanda , Rothenberger Meghan , Drekonja Dimitri
Published: July 2020

Background

Inappropriate antimicrobial use is common in the outpatient setting but often goes unaddressed by stewardship education. Residents might benefit from directed stewardship education.

Objective

We conducted a needs assessment of resident knowledge, attitudes, and behaviors regarding antibiotic use and stewardship in outpatient continuity clinics.

Methods

Internal medicine (IM) residents with continuity clinic at Minneapolis Veterans Affairs Health Care System were eligible. Antimicrobial prescriptions and number of visits were extracted from the Computerized Patient Record System (July 1, 2017–March 31, 2018). Antimicrobial rate (prescriptions per 1000 visits) was calculated for each resident. Results from a resident survey that included demographics, attitudes, and case-based multiple-choice knowledge questions were linked by unique identifier to antimicrobial rate.

Results

Prescription and visit data were available for 37 residents. Mean monthly antimicrobial rate was 51 prescriptions per 1000 visits (range 8–239). Surveys were completed by 19 residents (51%). Respondents were 32% female, 32% interns, and 11% international medical graduates. An online resource was most commonly used for prescribing guidance, whereas lectures and small group sessions for residents were rated as the most helpful educational modalities. Many respondents reported being unprepared to perform basic tasks related to antimicrobial stewardship. Median percentage correct was 57% of case-based knowledge questions (interquartile range 50%–71%).

Conclusions

Antimicrobial rates among IM residents at a VA outpatient continuity clinic are low and vary by provider. Residents agree with key antimicrobial stewardship concepts but lack preparation in tasks related to antimicrobial stewardship. Knowledge regarding antimicrobial prescribing was low.
Reforming EU merger control to capture ‘killer acquisitions’ – the case for caution
Authors: Levy Nicholas , Mostyn Henry , Buzatu Bianca
Published: July 2020

This article examines whether EU merger control rules should be recalibrated to address concerns said to arise from acquisitions of innovative start-ups by established digital platforms – commonly referred to as ‘killer’ or ‘nascent’ acquisitions. It assesses various proposals designed to remedy two failings: a perceived failure to review anti-competitive transactions due to inadequate jurisdictional thresholds and a perceived failure to detect competition problems during the merger review process. It argues that, given the large number of transactions already subject to merger control, any expansion of existing rules should occur only where there is clear evidence of a significant enforcement gap. In the view of the authors, there is no persuasive evidence that a material number of anti-competitive digital acquisitions are escaping antitrust scrutiny, that the analytical framework applied by the European Commission should be significantly changed, or that the methodological tools employed to review concentrations are unfit for purpose. The authors therefore disfavour wide-ranging changes to the EU's rules and instead propose a series of incremental improvements to ensure that EU merger enforcement is tailored to the digital age.
Aggregate damages: why the whole might not be the sum of the parts
Authors: Bell Joseph , den Boer Anna , Shah Kimela
Published: July 2020

Many legal regimes allow for the award of aggregate damages in collective or class claims. That is to say, an award may be made reflecting the losses of the class as a whole, with little or no information as to the losses suffered by individual class members. Economists are able to calculate damages at a class level without complete individual data by applying two different but not mutually exclusive sets of methodologies, which we refer to as ‘top-down’ and ‘sample-based’ approaches. This article discusses some of the advantages and pitfalls that may arise in estimating aggregate damages under each approach, and illustrates some circumstances in which the process of aggregation may lead to upward or downward bias in the estimate of total loss. We also compare the relative merits of each approach, and consider some of the practical steps by which such biases may be avoided.

Published: July 2020

The continuously escalating burden of COVID-19 pandemic is challenging the health care systems around the world. The healthcare professionals of different specialties throughout the globe are working day and night for its proper mitigation. Pharmacists are healthcare professionals who are working on the frontline for the management of COVID-19 in different settings. In this review, we highlight the potential roles pharmacists can play for effective management of COVID-19. The collaborative effort of all professionals, including healthcare and other stakeholders is necessary for the appropriate management of such pandemic. Pharmacists, having expertise in clinical as well as administrative aspects, can play a pivotal role in extended health services (EHS) from prevention to eradication of COVID-19. Firm determination, inter- and intra- professional collaboration, and legislative support are mandatory for the rational practice of professionalism in such disasters.

A Educação Estatística é uma área de estudos e pesquisas que se formou mediante a busca por compreender os processos de ensino e de aprendizagem de Estatística. No contexto brasileiro, em tais estudos, tem ganhado relevância o desenvolvimento de três competências, a literacia, o raciocínio e o pensamento alicerçados em ambientes de Modelagem Matemática. Esse artigo, de natureza teórica, tem como objetivo traçar um paralelo entre as etapas da Modelagem Matemática, os elementos do pensamento e os tipos de raciocínio estatístico, com a finalidade de apontar o que há de comum nas etapas propostas entre eles e, assim, contribuir com o desenvolvimento das pesquisas na área. O estudo apontou que o ambiente de Modelagem Matemática possui relações significativas com os tipos de raciocínio e os elementos do pensamento estatístico, o que nos permite afirmar que esse ambiente pode favorecer o desenvolvimento dessas competências.

Authors: Burgos Yomira , Vera Karen , Campuzano Juan Carlos
Published: July 2020

El cambio climático y las crecientes concentraciones espaciales representan amenazas para el desarrollo económico y social. En Ecuador, el Cantón Durán presenta un alto riesgo derivado de los movimientos de masa. Por ello, el presente proyecto tiene como propósito realizar un diagnóstico integral a la problemática del riesgo de deslizamiento y a su vez proponer estrategias de resiliencia urbana que permitan mitigar el impacto que causan sobre las comunidades. Para el desarrollo de este estudio se definieron dos etapas: la primera consistió en la identificación y delimitación del problema central a través de las metodologías de Design Thinking y Marco Lógico, mientras que en la segunda etapa se diseñó una matriz multicriterio para determinar las preferencias ante las estrategias propuestas a los diferentes actores del proyecto. Los resultados de esta investigación ubicaron al cantón Durán en un nivel de resiliencia baja y se concluye que las alternativas con mayor aceptación para mitigar el riesgo de deslizamiento son: la limpieza y estabilización de las bermas del talud, seguido de la implementación de un plan sectorial de vivienda y reubicación de viviendas; además de involucrar a la comunidad en la toma de decisiones.

Published: July 2020

El fútbol es el deporte con más aficionados en el planeta y, por ende, es de esperarse que se manejen cantidades exorbitantes de dinero. Particularmente a la hora de fichar jugadores, los clubes de fútbol desembolsan grandes cantidades de dinero y la pregunta en cuestión es: ¿se justifica que el valor de mercado de un jugador sea tan alto?. Por consiguiente, el presente estudio tiene por objetivo identificar cuáles son las variables que afectan al valor de mercado de un futbolista; para este caso en particular, se tomó en consideración una muestra de jugadores del top 35 de equipos de Conmebol en la temporada 2017-2018. Para lograrlo, se aplicó la metodología de regresión lineal múltiple bajo la aplicación de dos modelos. En el primero se tuvo en cuenta sólo variables referentes al desempeño. En el segundo modelo se incluyeron variables de naturaleza externa. Los resultados revelaron las variables que explican mayormente el valor de mercado de un jugador. A su vez, se aplicaron varias pruebas de validación al modelo final, las cuales demostraron su efectividad. Finalmente, se concluye que el grado de influencia que poseen los jugadores también constituye un factor determinante en el valor de mercado.

La existencia de una empresa está justificada por sus clientes, quienes son considerados como los activos más importantes. Ante mercados más competitivos y donde las necesidades de los clientes son cada vez más exigentes, las empresas buscan eficiencia en el uso y el análisis de datos. Perder clientes es más costoso que atraer nuevos clientes. El estudio sobre el comportamiento del cliente, particularmente su deserción, se ha convertido en una necesidad imperante dentro del ámbito empresarial. En la presente investigación se emplean técnicas de minería de datos para construir modelos de predicción de deserción de clientes, los cuales pueden ser aplicados dentro del mercado de desintermediación financiera. Los modelos estadísticos usados son: Árboles de decisión, bosques aleatorios y regresión logística, estos son evaluados en términos de precisión mediante área debajo de la curva de características de operación del receptor (AUC). La evaluación de los resultados, muestran que el bosque aleatorio tiene un mejor rendimiento que los otros modelos aplicados en el estudio.

BİRİNCİ DÜNYA SAVAŞI IRAK CEPHESİ’NDE KARŞIT GÜÇLERİN HAVACILIK FAALİYETLERİNİN ANALİZİ
Authors: KURT Deniz , KORKMAZ Erdal
Published: July 2020

1903 yılında ilk motorlu uçağın uçuşundan kısa bir süre sonra, uçaklar savaş aracı olarak ilk kez Trablusgarp Savaşı’nda kullanılmıştır. Ardından başlayan

Birinci Dünya Savaşı, uçakların savaş stratejisini belirleyen, yönlendiren bir mahiyet ve özellik almasına yol açmıştır. Savaş teknolojisinde yaşanan bu değişim hem

stratejik hem doktriner değişikliklerin gündeme gelmesine etki etmiştir. Bu durum karşıt güçlerin bu yeni savaş aracını üretme kapasitelerini artırmalarına ve cephe

savaşlarında etkin bir şekilde kullanımına yol açmıştır.

Birinci Dünya Savaşı’na Almanya’nın yanında katılan Osmanlı Devleti, savaşın başında altı uçakla muharebelere dâhil olmuştur. Savaş stratejisinin belirlenmesinde uçakların öneminin anlaşılması Almanya’dan uçak ve personel talebinde bulunulmasına yol açmıştır. Neticede savaş boyunca Türk havacıların yanında, Almanya’dan sağlanan 450 uçak ve 1.500 Alman havacı personelle cephelerde mücadele edilmiştir.

Savaşın seyri içinde Osmanlı Başkomutanlık Vekâletinin emri doğrultusunda uzak cephelerde 17 uçak bölüğü kurulmak suretiyle faaliyet gösterilmiştir. Bu kapsamda İngilizlerin Basra Körfezi’ne asker çıkarması ile açılan Irak Cephesi’nde, 2’nci ve 13’üncü Uçak Bölükleri kurulmak suretiyle cephe muharebelerine katkı sağlanmıştır.

İngilizler Irak Cephesi’nde savaşın başından itibaren hava gücü konuşlandırmak suretiyle etkin bir şekilde uçaklardan faydalanmıştır. Özellikle Kutü’l-Ammare Muharebeleri sırasında İngilizler tarafından Osmanlı kuvvetlerinin kuşatması altında bulunan birliklerine, havadan erzak ve malzeme atılmak suretiyle dünya tarihinde ilk kez hava ikmal faaliyeti gerçekleştirilmiştir.

Bu çalışmada, Irak Cephesi’nde mücadele eden karşıt güçlerin havacılık faaliyetleri, MSB Arşiv ve Askerî Tarih Daire Başkanlığı Arşivinde tespit edilen belgeler ve

kaynaklar çerçevesinde analiz, tenkit ve tahlil edilecektir.

The issue addressed in this research is how to design and build an expert systemwhich capable of diagnosing dog diseases that are caused by parasites, and how this expertsystem later can be useful for dog owners.This expert system is developed based on website technology in order to ease theaccessibility for the users. The finished product is expected to become useful for dog owners,to help them diagnose their dog disease based on the symptoms in order to give the propertreatment. The software development methodology used to develop this expert system is theWaterfall methodology, while the design is done using Unified Modeling Language (UML).The programming language used to build the expert system is PHP for the logic and MySQLfor the database, and the finished product is then tested using black box testing method. Totest system accuracy, disease diagnosis results from the expert system is then compared withdiagnosis results from the real human expert (veterinarian).This expert system is using forward chaining method and Bayes theorem. The forwardchaining concept, in this system, starting with the symptoms that are set into a reasoning andrules to reach some conclusions which in this case are the possible diseases. While the Bayestheorem is used to draw a conclusion from the possible diseases by calculating the probabilityof what kind of disease suffered based on the symptoms, and the weight of the probabilityitself. This expert system, however, still can be developed not only to diagnose diseases thatare caused by parasites, but also to diagnose all kind of dog diseases.
