La carta y el paquete. Travesías de la palabra escrita entre Argentina y Chile a fines del siglo XIX
Authors: Caimari Lila 
Published: June 2021

Objetivo: a partir de un intercambio epistolar entre individuos en Buenos Aires y Santiago de Chile, el trabajo se propone analizar las condiciones materiales de circulación de cartas e impresos entre ambas capitales, en el momento de la gran expansión postal de fines del siglo XIX. Metodología: el estudio se apoya en evidencia estadística producida por el Correo argentino y la Unión Postal Universal, que es interpretada y puesta en contexto mediante el cruce con un amplio espectro de fuentes cualitativas producidas por observadores contemporáneos, así como gestores y usuarios del sistema. Originalidad: en el marco de la expansión de estudios sobre “circulaciones” y “redes” transnacionales de fines del siglo XIX, el estudio propone una reconstrucción de las condiciones de posibilidad de esos intercambios en la región, a la vez que extiende el universo de estas prácticas a una escala mayor que la considerada hasta ahora. Conclusiones: además de dar cuenta del sistema de circulaciones que hizo posible el acercamiento informativo y cultural entre Buenos Aires y Santiago de Chile, se plantean las implicaciones de este fenómeno para la relación entre dichas capitales, en el marco de la emergencia de Buenos Aires como nodo distribuidor y polo periodístico y cultural.
Ni «Hombre del diablo», ni «Hombre de Dios»: Quevedo o «l’Homme des Lettres»
Authors: Marigno Emmanuel 
Published: June 2021

La presente reflexión arranca en la recepción que tuvo René Bouvier acerca de la obra de Francisco de Quevedo y Villegas, encasillándolo como «Homme du diable, Homme de Dieu».
Este trabajo parte del postulado de un escritor coherente desde perspectivas éticas, y pragmático desde experimentos e innovaciones estéticas. La meta de este artículo consiste, sin separar la vertiente filosófico-moral de la obra ficcional —sea poética o en prosa—, en demostrar que no se le puede calificar a Quevedo ni de «Homme de Dieu» y aun menos de «Homme du diable».
¿Quién es, pues, Quevedo, desde la perspectiva de un crítico del siglo XXI?
EXCHANGE RATE RESPONSE TO OIL PRICE AND POLITICAL SHOCKS: WHAT CAN NIGERIA DO?
Authors: KUTU Augustine Adebayo , ALORI David Alaba , NGALAWA Harold 
Published: June 2021

This study determines how political institution (factor) and oil prices play a significant role in exchange rate instabilities in Nigeria between and . Employing a VECM model with time series and structural analysis, the study decomposes the oil prices into positive and negative shocks. The findings show a symmetric impact from positive and negative oil shocks while political/institutional factor, on the contrary, indicates an asymmetric impact on exchange rates. The study, therefore, recommends that strong political institution that promotes good governance, accountability and transparency should be put in place. This will untimely reduce the cost of importation that prevents the country from reaping the benefits of positive oil price shocks. While this study employs one of the unique approaches to the study of exchange rates worldwide, it also provides insights to how institutional/political factor contribute to exchange rate instability in Nigeria.
Early Forecast of Maximum Amplitude due to Aftershocks by Applying Extreme Value Statistics to a Single Continuous Seismogram
Authors: Sawazaki Kaoru 
Published: June 2021

ABSTRACT
To evaluate the exceedance probability of maximum amplitude (EPMA) due to aftershocks, I developed a forecasting scheme based on the extreme value statistics applied to a single continuous seismogram of early aftershocks. By combining the general laws of aftershock activity (Gutenberg–Richter and Omori–Utsu laws) and a ground-motion prediction equation (including source, path, and site factors), I verified that the interval maximum amplitude of a continuous seismogram of aftershocks follows the non-stationary Frechet distribution (NFD), which is one of the extreme value distributions. The parameters of NFD are written explicitly from the parameters commonly used in seismology. By optimizing the NFD parameters through the maximum-likelihood method and using the maximum-likelihood estimates and their covariance values, I derived the EPMA due to aftershocks based on the Bayesian approach. The performance of the EPMA was examined by Monte Carlo simulations and real seismograms. The numerically generated maximum amplitude was predicted well from the EPMA, which was evident even in the period of intense seismicity in which many waveforms overlap in a seismogram. This performance was also robust for real seismograms of aftershocks for the 2008 Iwate–Miyagi Nairiku, Japan, earthquake. The maximum amplitudes observed for four days were mostly within the 10% and 90% EPMA curves issued within 3 hr of the mainshock. The proposed method does not need to evaluate source, path, and site factors because these factors are included in the estimated NFD parameters. Given that the proposed method allows single-station processing, a seismic “network” is not required. Therefore, the proposed algorithm will be easily implementable in a seismic observation system installed at important facilities. Also, the NFD parameters estimated robustly in the early lapse times may provide important knowledge regarding early aftershocks.
The Paratextual Labeling of Autistic-Authored YA Fiction as #OwnVoices: How YA Literary Culture Creates Space for Neurodivergent Authorship
Authors: Abad Jason Michael 
Published: June 2021

This essay considers the effect of #OwnVoices on autistic literary representation by analyzing how autistic authors use paratexts to prescribe for some readers ways of understanding autistic-authored texts while temporarily refraining from prescribing a particular method for others, allowing readers with opposing ideologies to first read the narrative before they encounter the more didactic elements of the text. Building on Gerrard Genette's theorization of the paratext, this essay compares the use of text and paratext in two works of autistic-authored fiction, Corinne Duyvis's On the Edge of Gone and Jen Wilde's Queens of Geek, to that of Mark Haddon's The Curious Incident of the Dog in the Night-Time, a work of allistic-authored YA fiction. The contrast between these two kinds of texts reveals how #ownvoices texts foreground the positionality of the author in ways that enable rather than foreclose discussions about the ethical representation of autistic people.

Natural gas is the basic fossil fuel in the global economy. According to the information published by Polskie Górnictwo Naftowe i Gazownictwo SA in the document Company Presentation, gas consumption in 2018 amounted to 19.7 billion m3. Due to the fact that the domestic reserves of natural gas are increasingly depleted, the demand for natural gas will be satisfied by growing imports. Balancing gas demand will require precise knowledge of the volume of domestic natural gas production. On the other hand, every year the Polish Geological Institute – National Research Institute (PIG – BIP) publishes Balance of mine resources in Poland. According to the publication on the state of resources as of December 31, 2018, 298 natural gas fields have been documented in Poland, 5 in the Baltic Sea region, 35 in Carpathians, 105 in Carpathian Foreland and 153 in Polish Lowland. The balance presented by PIG – BIP for 2018 showed the state of natural gas contingent resources in the amount of 139.93 billion m3 (total balance resources). The volume of industrial reserves of natural gas deposits as at December 31, 2018 was 66.64 billion m3. It should be emphasized that all data published in the Balance of mine resources in Poland are given in normal cubic meters. Therefore, the data published by PIG – BIP do not take into account the actual calorific value of natural gas produced from various fields. Starting from 2014, the basic accounting unit in Poland is the energy unit (kWh). Due to the introduction of the settlement in energy units, the value of 1 m3 of nitrogen-rich gas produced from the fields located in the Lowland region is lower than the value of gas produced from the Carpathian Foreland fields and the Carpathians. The average calorific value of gas produced from the Lowland fields is about 8.0 kWh/m3, while the average calorific value of gas produced from the rest of the Foreland is about 11.2 kWh/m3. The main goal of this article was to make a forecast of gas production from domestic deposits based on the Balance of mine resources in Poland published by the Polish Geological Institute –National Research Institute. The forecast of gas extraction from domestic deposits was made for the years 2020–2030. The production forecast was prepared for each gas-bearing region separately. In order to adjust the reported volumes to the applicable energy units, the gas production forecast for the Lowland fields was converted into high-methane gas production.

How Accurate Are ECT Patient Information Leaflets Provided by Mental Health Services in England and the Royal College of Psychiatrists? An Independent Audit
Authors: Harrop Christopher , Read John , Geekie Jim , Renton Julia 
Published: June 2021

BackgroundThe aims of this paper were to assess the accuracy of patient information leaflets about electroconvulsive therapy (ECT) in England, and assess compliance with National Institute for Health and Care Excellence (NICE) recommendations, and the principle of informed consent.MethodsFreedom of Information Act requests were sent to 51 National Health Service Trusts for a copy of their information leaflet. These, and three Royal College of Psychiatrists (RCPsych) leaflets, were scored on a 40-item accuracy measure.ResultsThirty-six Trusts (71%) provided leaflets. The number of accurate statements, from a possible 29, ranged from four to 20, with a mean of 12.8. The most commonly omitted accurate statements included: that previous treatments, including psychological therapy, should be tried first (mentioned by 12 Trusts); cardiovascular side effects (6); lack of long-term benefits (6); patients' right to take 24 hours to consider giving consent (1); memory loss higher in women and older people (0). The number of inaccurate statements averaged 5.8, out of 11, and ranged from two to nine. The most common inaccurate statements included: ECT corrects biological deficits (28); misleading claims of very low mortality risk (28); minimization of memory loss (23); claims that ECT saves lives (22); claims of very high improvement rates (19). The current (2020) RCPsych leaflet contained seven inaccurate statements and scored worse than two previous RCPsych leaflets.ConclusionsInformation leaflets about ECT comply neither with NICE recommendations nor the principle of informed consent. Patients are being misled about the risks they are taking and the limited nature of ECT's benefits.

Authors: Son Turan Semen 
Published: June 2021

The purpose of this exploratory study has been to provide insight into the success factors of ECF campaigns and, in particular, explore the role of trust. In specific, the research questions for this study are: (1) What dimensions of ECF success have been studied so far, and (2) is there any established literature on sustainability, blockchain technology and trust in the realm of ECF. To that end, a systematic literature review is conducted by investigating ISI Web of Science and Scopus, two major academic databases, through relevant keyword combinations. The theoretical framework relies on signaling, legitimacy and stakeholder theories. Findings indicate that the role of trust is an emerging theme, and sustainability and BT in relation to trust, to the best of the author’s knowledge, is not yet focused upon in crowdfunding research. This study contributes to the literature of crowdfunding and entrepreneurship.
Evolución de la mortalidad atribuible al alcohol en España según edad, sexo, causa de muerte y tipo de bebedor (2001-2017)
Authors: Donat Marta , Sordo Luis , Belza María José , Hoyos Juan , Regidor Enrique , Barrio Gregorio 
Published: June 2021

En España no hay estimaciones recientes de la mortalidad atribuible a alcohol con datos de consumo de alcohol españoles. El objetivo es estimarla y conocer la evolución entre 2001 y 2017 en personas ≥15 años, según sexo, edad, periodo, causa de muerte y tipo de bebedor. Se utilizó el enfoque causa específico y la ecuación de Levin. El consumo de las encuestas se corrigió por subestimación con respecto a las estadísticas de ventas y se consideró el consumo pasado y los atracones de alcohol. El número medio anual de muertes atribuibles a alcohol en 2010-2017 fue 14.927, un 58,6% prematuras (<75 años). La tasa de mortalidad atribuible a alcohol estandarizada por edad fue 39,4/ 100.000 habitantes, representando un 3,9% de la mortalidad general. Usando porcentajes estandarizados un 68,7% correspondió a bebedores de alto riesgo. Las causas de mortalidad atribuible a alcohol más frecuentes fueron cáncer (43,8%) y enfermedades digestivas (32,9%). La tasa de mortalidad atribuible a alcohol fue 3,5 veces mayor en hombres que en mujeres (con cocientes más elevados para jóvenes y causas externas). Entre 2001-2009 y 2010-2017 la tasa media anual disminuyó un 16,8% (60,7% en 15-34 años; 19,4% en hombres y 9,8% en mujeres). La contribución de los bebedores de alto riesgo y de las enfermedades digestivas y causas externas al riesgo de mortalidad atribuible a alcohol disminuyó ligeramente entre los dos períodos, mientras que aumentó la contribución del cáncer y enfermedades circulatorias. Estas estimaciones son conservadoras. La contribución del alcohol a la mortalidad general es importante en España, requiriendo medidas colectivas para reducirla.

Internal Magnetic Lengthening and Reconstruction with Free TRAM Flap After Traumatic Transfemoral Amputation
Authors: Kuruoglu Doga , Sems Stephen A. , Sampson Brandon P. , Carlsen Brian T. 
Published: June 2021

Case:
This is a case of a 41-year-old man who sustained a traumatic proximal transfemoral amputation with loss of adductor function and inadequate soft tissue. Wound closure was achieved with split-thickness skin grafting. Subsequently, femoral lengthening was achieved with an internal magnetic lengthening nail. He underwent a free transverse rectus abdominis myocutaneous (TRAM) flap to resurface the limb and provide more stable soft tissue, adductor repair, and further lengthening because of his prominent abduction contracture and inadequate soft tissue. This allowed independent ambulation with a prosthetic.

Conclusion:
Femoral lengthening with soft-tissue reconstruction improved prosthetic function and ambulation in a patient with a short transfemoral amputation.
Schedule Optimization To Accelerate Offshore Oil Projects While Maximizing Net Present Value in the Presence of Simultaneous Operations, Weather Delays, and Resource Limitations
Authors: Almedallah M. K. , Clark S. , Walsh S. D. C. 
Published: June 2021

SummaryCost and schedule overruns are endemic problems for offshore oil projects. This can be partly attributed to weather delays, resource limitations, and scheduling risks. The problem is further compounded because of the large number of interdependent activities, such as drilling and platform installation, typically involved in the buildup period of oilfield development. As a result, there is a pressing need to find robust project planning and scheduling models that consider these interacting components and associated risks in offshore oil projects.This study considers three techniques to optimize offshore oil project schedules while accounting for the impact of numerous field activities and potential delay factors; these are mixed-integer linear programming (MILP), single-objective genetic algorithms (SOGAs), and nondominated sorting genetic algorithms (NSGA-II). The study compares the performance of each using a model that integrates field planning with scheduling while accounting for weather delays, resource limitations, and simultaneous operations (SIMOPS; i.e., the ability to conduct more than one activity at once). The first two techniques (MILP and SOGA) optimize the oilfield schedule based on a single objective, which is to maximize net present value (NPV) or minimize project time. However, the maximum NPV schedule may result in a longer project time, whereas the shortest project time may result in a lower NPV. Therefore, the third method using NSGA-II finds Pareto-optimal schedules that balance these competing objectives. Four case studies are provided to compare the MILP and SOGA approaches with the suggested multiobjective NSGA-II.

Published: June 2021

Summary
One of the most critical issues in the oil and gas industry is the dewatering of the pipelines used for natural gas transportation, and foam injection seems to be a prominent solution. This work has two goals: The main one concerns the development of an optical tool to measure the liquid holdup in foamy flows and perform the flow regime characterization, whereas the secondary goal is to quantify the effectiveness of surfactant injection in reducing the liquid loading. In this paper, we present the results of an experimental campaign aimed at the characterization of gas-liquid-foam flows in a horizontal pipe. Initially, liquid loading measurements for gas and liquid superficial velocities, ranging from 0.41 to 2.30 m/s and from 0.03 to 0.06 m/s, respectively, were performed by means of a specifically developed optical method. For each liquid superficial velocity, the minimum liquid holdup was found to lie in the proximity of the boundary between plug and stratified flow regime, with a superficial gas velocity between 0.44 and 0.90 m/s. Hence, the plug flow region corresponds to the best operating condition to perform the pipeline dewatering procedure. Moreover, the drift-flux model usually adopted for ordinary two-phase gas-liquid flows seems to fit well with the measured values of void fraction.
