Distributed summer air temperatures across mountain glaciers: climatic sensitivity and glacier size
Authors: Shaw Thomas E. , Yang Wei , Ayala Álvaro , Bravo Claudio , Zhao Chaunxi , Pellicciotti Francesca
Published: August 2020

Abstract. Near-surface air temperature (Ta) is highly important for modelling glacier ablation, though its spatio-temporal variability over melting glaciers still remains largely unknown. We present a new dataset of distributed Ta for three glaciers of different size in the south-east Tibetan Plateau during two monsoon-dominated summer seasons. We compare on-glacier Ta to ambient Ta extrapolated from several, local off-glacier stations. We parameterise the along-flowline climatic sensitivity of Ta on these glaciers to changes in off-glacier temperatures and present the results in the context of several available distributed on-glacier datasets around the world. Climatic sensitivity decreases rapidly up to 2000–3000 m along the down-glacier flowline distance. Beyond this distance, both the Ta of the Tibetan glaciers and global glacier datasets show a slower decrease of climatic sensitivity. In general, observations on small glaciers (with
The Reality of Strategic Thinking Practice at the Faculty of Education, Damietta University: A Faculty Perspective
Authors: Al Basel Mayada M. , Soliman Hanaa I.
Published: August 2020

The present study aims at investigating the reality of strategic thinking practice at the Faculty of Education, Damietta University from the perspective of the faculty members. It adopted the descriptive approach and utilized a ten-domain questionnaire. The results showed that although the Faculty has an approved strategic plan and a quality assurance unit, the mechanisms of following up the implementation of the strategic plan are inadequate. Moreover, the Faculty’s quality assurance unit has not developed integrated databases of its various activities. The study recommended that the Council of the Faculty of Education should make and follow up the implementation of an updated and approved action plan. Training courses on the specifications and making reports of the educational programs, syllabi, etc. should be offered to the faculty members. Additionally, integrated databases of the various activities of the Faculty’s quality assurance unit should be developed.

Published: August 2020

El servicio público de educación superior es ofertado por el Estado nicaragüense y español a través de instituciones especializadas, estas son las universidades, sean de naturaleza pública o privada. El régimen jurídico y administrativo bajo el cual operan estas instituciones es por medio del modelo descentralizado por servicio o por colaboración. De manera que el objetivo de este pequeño estudio es contrastar el grado de autonomía que tienen las instituciones de educación superior en el régimen de descentralización por servicio o por colaboración que los respectivos marcos jurídicos español y nicaragüense les otorgan a las universidades sean éstas públicas o privadas. Para ello, se aborda de forma sucinta una panorámica doctrinaria sobre lo que es descentralización por servicio y colaboración. Se describe los rasgos particulares de las Universidades públicas y privadas tanto en España como en Nicaragua y, finalmente se realiza una comparación de los niveles de autonomía que presentan las instituciones de educación superior en España y Nicaragua. La Metodología utilizada en la investigación jurídica es teórica documental y el tipo de estudio descriptivo y comparativo del grado de autonomía en el régimen de descentralización por servicio o por colaboración de las universidades públicas y privadas de acuerdo a la legislación universitaria de España y Nicaragua. Por lo que las técnicas de investigación fueron esencialmente documentales (fuentes primarias del conocimiento [Constituciones, leyes, etc.], fuentes bibliográficas específicas relacionados con la descentralización administrativa.
Novel use of esophageal overtube and water flushes as a safety indicator and facilitator for the push technique in esophageal food impaction
Authors: Shao Paul P , Grewal Jasleen K , Custer Adam M , Leung Felix
Published: August 2020

Esophageal food impaction requires urgent endoscopic intervention either by extraction or pushing into the stomach. Due to risks of perforation, controversy exists between when to extract verses when to push the food bolus. There are no clear guidelines on when it is safe to push a food bolus; endoscopists rely on their subjective experiences and judgment. We present a case with a novel use of an esophageal overtube and water flushes to determine the safety of pushing a food bolus and facilitate passage into the stomach.
New Reconstruction Method for Needle Contrast Optimization in B-Mode Ultrasound Image by Extracting RF Signal Parameters in Frequency Domain
Authors: Susanti Hesty , Suprijanto Suprijanto , Kurniadi Deddy
Published: August 2020

Ultrasound-guided needle insertion has become standard in medical interventional procedures. Regardless of its advantages, it still has crucial problems related to needle visibility. Some technical factors affect the visibility with non-linear characteristic, i.e. frequency, insertion angle and depth. Here, backscattered signal parameters from measurement were compared to a simulation of a resonance scattering model. Raw radio frequency (RF) data were reconstructed with a new method to represent unique information on total backpropagation from the needle, which consists of non-resonance and resonance scattering components. The result suggests that reconstruction of the needle in B-mode images should be derived from the maximum power spectral density and the energy spectral density to optimize the contrast of the needle. In measurements with the center frequency at 1.87 MHz, the effect of resonance scattering on the total backpropagation around critical angles could be observed more clearly with this method than with standard reconstruction based on the signal envelope. The simulation showed that the fractional bandwidth of the spectrum of the backscattered pressure field centered at 1.87 MHz was relatively optimal at 40% to 100%. So that the simulation of the resonance scattering model can be used to predict the backscattered response from the needle, it must be able to confirm it to the real conditions of RF data with random characteristics. Therefore, extraction of the backscattered pressure field in a simulation with fractional bandwidth should be a concern.
Improvement of Tar Removal Performance in Biomass Gasification Using Fixed-Bed Biomass Filtration
Authors: Dafiqurrohman Hafif , Kosasih Dadan , Putra Arief Wildhan Naro , Setyawan Muhammad Ismail Bagus , Surjosatyo Adi
Published: August 2020

Several studies have proven the efficiency of gasification as a thermal process in terms of material decomposition and chemical energy. Synthetic gas (syngas) is a gasification product that can be used as an energy source. However, it needs to undergo treatment to remove the tar content, which could cause several issues in the combustion system. Tar removal can be conducted through biomass filters. In this study, three types of filters were investigated: biochar, rice straw, and rice husk filters. Three thicknesses of the porous media (30, 40, and 50 cm) were investigated. The results revealed that porous media thickness significantly affects tar removal efficiency, as the efficiency was found to increase with the thickness. Biochar was proven to be the best filter media among the three types, with a tar removal efficiency of 59.45% at a thickness of 50 cm.
Macedonian Intercalary Months and the Era of Azes
Authors: Falk Harry , Bennet Chriss
Published: August 2020

The Azes era was identified with the Vikrama era when a date in a year “of King Azes the Great” was read for the first time on the Indravarman casket in 1978, making more likely what had been suspected before. Doubts about this identification have been brought forward occasionally. The present study starts from a new reading of the so-called Traṣaka reliquary. In addition to its month called “intercalary Gorpiaios” a year number could be read as 172. This particular month is only intercalary in the Arsacid model of the Macedonian calendar and here it occurs only once in every 19 year cycle. Starting from a Vikrama year 1, year 172 would not produce an intercalary Gorpiaios. Starting from those years which in fact produced one, the beginning of the era of Azes must be shifted earlier or later than the Vikrama starting point. A series of comparisons with the so-called Yavana era and the Arsacid era led to a new start of the Azes era in 48/7 (autumn-based year) or 47/6 BC (spring-based year). This sheds light also on the nature of the starting point of the Kaniṣka era.
The Towers of Yue
Authors: Milburn Olivia Rovsing
Published: August 2020

This paper concerns the architectural history of eastern and southern China, in particular the towers constructed within the borders of the ancient non-Chinese Bai Yue kingdoms found in present-day southern Jiangsu, Zhejiang, Fujian and Guangdong provinces. The skills required to build such structures were first developed by Huaxia people, and hence the presence of these imposing buildings might be seen as a sign of assimilation. In fact however these towers seem to have acquired distinct meanings for the ancient Bai Yue peoples, particularly in marking a strong division between those groups whose ruling houses claimed descent from King Goujian of Yue and those that did not. These towers thus formed an important marker of identity in many ancient independent southern kingdoms.

Die Rechtsstellung von Asylbewerbern im Asylzuständigkeitssystem der EU
Authors: Pelzer Marei
Published: August 2020

Das Werk untersucht das Asylzuständigkeitssystem aus individualrechtlicher Perspektive. Gezeigt wird, dass die Dublin-III-VO als ein auf den subjektiven Rechten der Asylbewerber fußendes System kaum noch Raum für eine rein objektivrechtliche Lesart des Zuständigkeitssystems lässt. Somit stellt die Supranationalisierung nicht nur eine evolutionäre Weiterentwicklung des völkerrechtlichen Asylzuständigkeitssystems dar, sondern beschreibt einen grundlegenden Systemwechsel.
A Case Report: Point-of-care Ultrasound in the Diagnosis of Post-Myocardial Infarction Ventricular Septal Rupture
Authors: Portuguese Andrew , Abdulla Khaled , Vornovitsky Michael , DeAngelis John
Published: August 2020

Introduction: Ventricular septal rupture (VSR) is a rare complication of ST-elevation myocardial infarction (STEMI), typically discovered post-revascularization.

Case report: We present the first case of VSR detected on point-of-care ultrasound (POCUS) in the emergency department immediately prior to emergent angiography, with management positively affected by this discovery. The VSR was quickly confirmed via right heart catheterization. Subsequently, hemodynamic stability was achieved using an intra-aortic balloon pump. A delayed surgical VSR repair, with concomitant coronary artery bypass grafting, was implemented for definitive management.

Conclusion: This case highlights the utility of POCUS in a STEMI patient with a suspected mechanical complication.
Point-of-care Echocardiogram as the Key to Rapid Diagnosis of a Unique Presentation of Dyspnea: A Case Report
Authors: Moore Michael , Dilcher Brian , MInardi Joseph , Quedado Kimberly , Shaver Erica
Published: August 2020

Introduction: Dyspnea is commonly evaluated in the emergency department (ED).The differential diagnosis is broad. Due to the large volume of dyspneic patients evaluated, emergency physicians (EP) will encounter uncommon diagnoses. Early, liberal application of point-of-care ultrasound (POCUS) may decrease diagnostic error and improve care for these patients.

Case Report: We report a 48-year-old male presenting to the ED with cough and progressively worsening dyspnea for 11 months after multiple healthcare visits. Using POCUS, the EP was immediately able to diagnose a severe dilated cardiomyopathy (DCM) with left ventricular thrombus.

Conclusion: Given that non-ischemic DCM is one of the most common etiologies of heart failure, often presenting with respiratory symptoms, POCUS is key to rapid diagnosis and, along with modalities such as electrocardiography and chest radiograph, should be standard practice in the workup of dyspnea, regardless of age or comorbidities.

Authors: Beaupre II Randall , Petrie Cody , Toledo Alexander
Published: August 2020

Introduction: The coronavirus disease of 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 is a global pandemic that expresses itself with a wide variety of presenting symptoms in patients. There is a paucity of literature describing the dermatologic manifestations of the virus, particularly in the United States.

Case Report: Here we present a case of COVID-19 that manifested with a purpuric rash on the lower extremities and a maculopapular eruption on the abdomen in a patient in acute diabetic ketoacidosis and normal platelet count.

Discussion: The reported presenting symptoms of patients with COVID-19 vary greatly. This is the first documented case of COVID-19 presenting with mixed cutaneous manifestations of a purpuric as well as maculopapular rash.

Conclusion: The cutaneous lesions associated with the COVID-19 infection may mimic or appear similar to other well-known conditions. We illustrate a case of COVID-19 infection presenting with purpuric rash on the lower extremities and a maculopapular rash on the abdomen.
A Case Report of Acute Motor and Sensory Polyneuropathy as the Presenting Symptom of SARS-CoV-2
Authors: Kopscik Michael , Giourgas Barbra , Presley Bradley
Published: August 2020

Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) typically presents with respiratory illness and fever, however some rare neurologic symptoms have been described as presenting complaints. We report a case of an acute motor and sensory polyneuropathy consistent with Miller-Fisher Syndrome (MFS) variant of Guillain Barre Syndrome (GBS) as the initial symptom.

Case Report: A 31-year old Spanish speaking male presents with two months of progressive weakness, numbness, and difficult walking. He had multiple cranial nerve abnormalities, dysmetria, ataxia, and absent lower extremity reflexes. An extensive workup including infectious, autoimmune, paraneoplastic, metabolic and neurologic testing was performed. Initially SARS-CoV-2 was not suspected based on a lack of respiratory symptoms. However, workup revealed a positive SARS-CoV-2 polymerase chain reaction test as well as presence of Anti-Ganglioside – GQ1b (Anti-GQ1b) immunoglobulin G antibodies.

Discussion: Miller Fisher syndrome (MFS) is a variant of Guillain-Barre syndrome (GBS) characterized by a triad of ophthalmoplegia, ataxia, and areflexia. The patient’s exam and workup including Anti-GQ1b is consistent with MFS.

Conclusion: SARS-CoV-2 infection in patients can have atypical presentations similar to this neurologic presentation. Prompt recognition and diagnosis can minimize the risk of transmission to hospital staff and facilitate initiation of treatment.
Association Analysis of Monoamine Oxidase-A Gene Promoter Polymorphism (MAOA uVNTR) for Antisocial Behavior: Absence of the Counting Number Repeats in Central Iran
Authors: Khosravian Maryam , Nikpour Parvaneh , Emadi-Baygi Modjtaba , Soleimanpour Ali , Yadollah Moghadam Fereidoun
Published: August 2020

Background: The MAOA gene is located on the X chromosome (Xp11.23). Several studies have established a VNTR (Variable Number Tandem Repeat) polymorphism in the upstream of the MAOA gene transcriptional initiation region named uVNTR which is correlated with the risk of antisocial behavior. Objectives: This study aimed to investigate the association between MAOA genotypes and the risk of violent behavior in a cohort of violent and age-matched non-violent individuals. Methods: In the current case-control study, MAOA uVNTR was genotyped in a cohort of 88 violent and 95 age-matched non-violent individuals. Individuals were genotyped for the MAOA uVNTR by performing PCR, gel electrophoresis, and sequencing. Furthermore, a chi-square test was performed using SPSS, and a p-value of less than 0.05 was considered statistically significant. Results: We identified three MAOA uVNTR allelic variants: They were harboring 3.5, 4.5, and 5.5 repeated sequences. Alleles with 2, 3, 4, 5, and 6 repeats were not observed in any of the two examined groups. Conclusions: We did not detect a statistically appreciable association between antisocial behavior and allele frequencies in the studied population in central Iran.
Social network sites, fear of missing out, and psychosocial correlates
Authors: Classen Ben , Wood Jay K. , Davies Patsi
Published: August 2020

The use of Social Network Sites (SNSs) has grown to become a ubiquitous aspect of daily life in developed countries throughout the world. This rise of social media has resulted in increased public concern regarding the way in which individuals engage with SNSs, and the consequences of frequent SNS use. The Fear of Missing Out (FoMO) is an example of a social psychological phenomenon which has recently received attention as a significant factor associated with experiences of SNS engagement. The following study sought to contribute to developing understandings of SNS use and FoMO. This was achieved by assessing the extent to which FoMO mediated the relationships between SNS engagement and four other psychosocial factors (psychological need satisfaction, social capital, public self-consciousness, and public self-monitoring). Quantitative data were collected from a student volunteer sample of 218 New Zealand SNS users and analysed using a series of regression analyses. Relationships between each of the assessed psychosocial variables and rates of SNS engagement were found to be mediated by FoMO. The findings of this study support the view that FoMO plays an important role in understanding the range of complex and interrelated psychosocial factors relating to rates of SNS engagement.
Levinas’s Restlessness: “God and Philosophy” without Consolation
Authors: Davies Paul ,   Philosophy Documentation Center
Published: August 2020

The paper reflects on the experience of reading Levinas’s ‘God and Philosophy’ paying particular attention to the ways in which it would have us read the word ‘God.’ Levinas refuses to let the word become the property of even the most radical treatment of religious faith. The word, the biblical word, must never serve the self-consolation of philosophy. Many of Levinas’s readers regret this aspect of his writing, but the paper argues that ‘God and Philosophy’ offers an exemplary introduction to Levinas’s most developed style of writing and thinking, and it does so while bringing to mind the question of the relation between Levinas’s (and, by implication, the reader’s) philosophy and their religion. The second part of the essay considers possible contexts (religious, philosophical and cultural) in which this question and ‘God and Philosophy’ itself can perhaps best be understood.
Poetry as Spiritual Exercise
Authors: Wahl Jean , Duvernoy Russell J. , Lura Christopher , Hansen Anna-Marie ,   DePaul University
Published: August 2020

“La Poésie Comme Exercice Spirituel” first appeared in a 1942 issue of Revue Fontaine edited by Jacques and Raissa Maritain and was subsequently republished in Wah’s 1948 text Poésie, Pensée, Perception, published by Calmann-Lévy. The following is a translation of the Fontaine version. I have noted all of the variations from the latter version in the notes. As I emphasize in my commentary, the piece is a notable display of Wahl’s eclectic range of influences. Most importantly, it shows the extent to which his interest in radical empiricism and process metaphysics informs his creative approach to the intersection of poetics and metaphysics. These interests are not explicitly named in the essay, and yet their influence is pervasive. The essay also includes several moments of substantial resonance with the work of Gilles Deleuze, as noted in the commentary.
FAMÍLIA EXTENSA OU ADOÇÃO: CRITÉRIOS PARA A EFETIVIDADE DO PRINCÍPIO CONSTITUCIONAL DO MELHOR INTERESSE DA CRIANÇA E DO ADOLESCENTE NOS PROCESSOS DE COLOCAÇÃO EM FAMÍLIA SUBSTITUTA
Authors: Souza Vanessa Ribeiro Corrêa Sampaio , Fernandes Manoela Gomes
Published: August 2020

A Lei nº 8.069/90, ao tratar de aspecto do direito à convivência familiar, institui ordem que privilegia a família extensa em detrimento do vínculo adotivo. Evidencia-se, assim, que o Estatuto ainda prioriza os vínculos biológicos, embora a afetividade tenha se constituído como um importante valor no direito de família contemporâneo. Faz-se necessário, portanto, indagar se a referida hierarquia familiar normativa realiza o princípio do melhor interesse da criança e do adolescente diante da necessidade de aplicação da lei a partir de uma interpretação que considere a unidade constitucional como seu viés condutor. Verificadas as circunstâncias que caracterizam a vida relacional do infante e constatando-se que a manutenção dos vínculos biológicos não representa o seu melhor interesse, coloca-se a necessidade de relativizar a legislação. Diante disso, o presente trabalho objetiva analisar, empregando o método dedutivo e a técnica de pesquisa documental e teórica, a aplicação do princípio do melhor interesse da criança e do adolescente e a flexibilização do cumprimento da regra que estabelece a preferência pela família extensa.

Published: August 2020

O presente artigo de revisão utiliza o método lógico-sistemático para analisar a capacidade processual dos animais, considerada em sentido amplo, no Brasil e na América Latina. Inicialmente, o artigo apresenta os principais precedentes dos tribunais latino-americanos, que reconhecem os animais como sujeitos de direito e com capacidade de defender em juízo interesses próprios. Em seguida, revisa o conceito de capacidade processual no Direito brasileiro, em sua tríplice configuração. Na sequência, analisa o Decreto federal 24.645/1934 para demonstrar que os animais possuem capacidade de ser parte processual, desde que devidamente assistidos por seus substitutos legais, pelas sociedades protetoras ou pelo Ministério Público. Por fim, após constatar a omissão doutrinária sobre o tema, analisa as vantagens e desvantagens em se atribuir capacidade de ser parte aos animais.

Professions today: self-criticism and reflections for the future
Authors: Sarfatti Larson Magali
Published: August 2020

This article revisits my 1977 work The Rise of Professionalism, outlining what I now believe was wrong in my book and what I think may still be useful in order to move on to some ideas about the present situation. One of the predominant questions is whether we should completely merge the study of professions with that of knowledge-based occupations. And if we accept that the age of experts has entirely supplanted the former public life of trustee professions, what consequences derive? What trends will future research need to consider? These tentative and incomplete ideas should be read as calls for further research.

Perils and pitfalls of mixed-effects regression models in biology
Authors: Silk Matthew J. , Harrison Xavier A. , Hodgson David J.
Published: August 2020

Biological systems, at all scales of organisation from nucleic acids to ecosystems, are inherently complex and variable. Biologists therefore use statistical analyses to detect signal among this systemic noise. Statistical models infer trends, find functional relationships and detect differences that exist among groups or are caused by experimental manipulations. They also use statistical relationships to help predict uncertain futures. All branches of the biological sciences now embrace the possibilities of mixed-effects modelling and its flexible toolkit for partitioning noise and signal. The mixed-effects model is not, however, a panacea for poor experimental design, and should be used with caution when inferring or deducing the importance of both fixed and random effects. Here we describe a selection of the perils and pitfalls that are widespread in the biological literature, but can be avoided by careful reflection, modelling and model-checking. We focus on situations where incautious modelling risks exposure to these pitfalls and the drawing of incorrect conclusions. Our stance is that statements of significance, information content or credibility all have their place in biological research, as long as these statements are cautious and well-informed by checks on the validity of assumptions. Our intention is to reveal potential perils and pitfalls in mixed model estimation so that researchers can use these powerful approaches with greater awareness and confidence. Our examples are ecological, but translate easily to all branches of biology.

The little known fairyfly (Hymenoptera, Mymaridae),Platystethynium(Platystethynium)triclavatum(Donev & Huber, 2002), comb. n. fromPseudocleruchusDonev & Huber, 2002, is newly recorded as an egg parasitoid ofBarbitistes vicetinusGalvagni & Fontana, 1993 (Orthoptera, Tettigoniidae). This bush-cricket is endemic to northeastern Italy (mainly Euganean Hills of Veneto Region), where it has recently become an economically significant agricultural and forest pest. Data on discovery, distribution, and some remarkable biological traits of this gregarious egg parasitoid are presented. Its identification and availability of many well-preserved fresh specimens have made possible to re-definePseudocleruchusDonev & Huber, 2002 syn. n., with type and the only described speciesPseudocleruchus triclavatusDonev & Huber, 2002, as a synonym ofPlatystethyniumOgloblin, 1946 and its nominate subgenus,P. (Platystethynium), and also to describe the brachypterous male ofP. (Platystethynium)triclavatum. It is the first known male for the entire genus. Enlarged mandibles of the megacephalous males are used to chew holes in the hard chorion of the host egg, allowing fully winged females, whose mandibles are strongly reduced and do not cross over, to emerge after mating with the males inside it. Up to 136 individual parasitoids (about 77 on average) can hatch from a single egg ofB. vicetinus, with their sex ratio being strongly female biased (80–97% females per egg).
Беспощадное освоение Колымы, последний рубеж- южная часть хребта Черского, "Природа"

Published: August 2020

Во второй четверти прошлого века началось освоение Верхней Колымы, и суровые приполярные нагорья были превращены в горнопромышленный район по добыче золота. В условиях многолетней мерзлоты архаичные приемы россыпной золотодобычи разрушают долины и таликовые поймы рек, в которых сосредоточен почти весь биотический потенциал горно-таежного ландшафта. Пространство, пронизанное «метастазами» россыпной золотодобычи, занимает уже около 50 тыс. км2. В результате в истоках крупнейшей восточносибирской реки сложилась экологическая аномалия, хорошо видимая из космоса. Компенсировать масштаб экологической разрухи могло бы развитие региональной экологической сети и резервирование территорий, сохраняющих высокую природоохранную ценность. В этом отношении южная окраина хребта Черского заслуживает особого внимания. Хребты Чёрге и Охандя пока еще служат барьером, защищающим этот сохраняющий уникальную природную и историко-культурную ценность участок от натиска старателей. Для обследования южной окраины Черского в июле-августе 2018 г. была проведена экспедиция, организованная Институтом биологических проблем Севера и Русским географическим обществом. В статье приводятся первые или малоизвестные сведения о ландшафтах, биоте и истории отдаленной области российской субарктики, сохраняющей уникальные черты и высокую природоохранную ценность в условиях ультраконтинентального климата и нарастающих экологических угроз со стороны горнодобывающей промышленности. Особое внимание уделено физико-географическим особенностям и биологическому разнообразию крупных тектонических озер Дарпирской впадины. На основе результатов этой экспедиции разработано предложение о создании в описываемом районе национального парка «Черский».
Time Series Predictive Models for Social Networking Media Usage Data: The Pragmatics and Projections
Authors: Jayaram M. A. , Jayatheertha Gayitri , Rajpurohit Ritu
Published: August 2020

Aims: We have set forth three main objectives in the work presented in this paper, they are namely, to study how social networking media usage is surging over the time for three social media networks viz., Facebook, Twitter and LinkedIn, ii.to develop best fitting time series predictive models for predicting future usage of three network media  and, iii. to make a comparative analysis to herald the ups and downs noticed in the usage across three network media considered.

Study Design: Application of time series techniques for the analysis of social network user’s data. The main research question addressed by this work is to see how time series models augurs for time dependent data such as the one chosen in this research.

Place and Duration of Study: Research Center, Department of Master of Computer Applications, Siddaganga Institute of Technology, Tumakuru, Karnataka, India, between January 2020- April 2020.

Methodology: The work delved on collection three social network users (Facebook, LinkedIn, and Twitter) data for a span of nine years i.e., for the tenure 2011-2019. One dimensional, two dimensional and three dimensional visual analytics is made prior to time series analysis. Time series predictive analytics involved development of best fits for prediction. To select the best fits among linear, polynomial, exponential, power function and logarithmic models, mean absolute error and root mean square error metrics were used.

Results: Linear, polynomial function trend lines proved to be the best for Facebook, LinkedIn and Twitter respectively with low values of MAE and RMSE and high values of regression coefficients as compared with other kinds of models. Apart from the error metrics, the Theil’s U-statistic values of 0.928, 1.008 and 1.21 for Facebook, Twitter and LinkedIn also heralded the fact that these functions are superior models when compared with other naïve models. It is also projected that by 2025, Facebook will see 10,000 billion, followed by LinkedIn at 1500 billion while Twitter would see 750 billion people if same kind of surge trend prevails in user numbers across three networks considered in this research.

Conclusion: This paper presented a unique work which is supposedly deemed to be the first of its kind to the best of the knowledge of authors. The models come with a limitation that, they can provide accurate projection if the same trend prevails in the pattern of upheavals in usage.

SOCIOLOGIA DIGITAL: PARA ALÉM DO DIGITAL, RUMO AO SOCIOLÓGICO
Authors: Pinho Thiago
Published: August 2020

A subdisciplina de sociologia digital tem, recentemente, começado a atrair a atenção dos/as sociólogos/as, particularmente no Reino Unido. Nesse artigo, eu irei revisar algumas das características mais interessantes que têm surgido até agora no corpo acadêmico da sociologia digital. Alguns podem contestar argumentando que a sociologia digital é simplesmente um novo nome para um tipo de pesquisa sociológica já há muito tempo estabelecida, interessada em tecnologias online e computadorizadas. Contudo, meu argumento é que a sociologia digital, como tem se desenvolvido particularmente no Reino Unido, se distingue por desenvolver uma abordagem teórica distinta, que levanta questões importantes no que diz respeito à natureza da pesquisa social e da sociologia como uma disciplina e uma prática na era digital. Nesse sentido, a sociologia digital tem implicações mais amplas que simplesmente o estudo de tecnologias digitais.

There is relatively limited research on psychopathy in non‐Caucasian ethnic groups and even less on the utility of the Psychopathy Checklist‐Revised (PCL‐R) that focuses on PCL‐R facet and item scores in predicting violent recidivism. In this study, we assessed the utility of the PCL‐R in prospectively predicting violent versus nonviolent recidivism during an 11‐year follow‐up window. A high‐risk sample of 451 incarcerated Korean male offenders was assessed on the PCL‐R at baseline. A total of 445 were reconvicted after release (353 violent and 92 nonviolent recidivists). Psychopathy facet scores were higher in violent compared to nonviolent recidivists. Facet 2 (affective) showed the strongest effect size (Cohen's d = 0.53; Percentage change in odds = 22.6%) in predicting violent recidivism. Analyses of the four items constituting the affective facet indicated that callous/lack of empathy (Percentage change in odds = 134.4%) and failure to accept responsibility (Percentage change in odds = 94.5%) were the strongest predictors of violent recidivism. Findings are to our knowledge the first to document the utility of the PCL‐R in distinguishing violent from nonviolent recidivism and highlight the role of affective impairment (particularly lack of empathy) in violent recidivism.

Purpose

Ultrasound grayscale imaging preset optimization has often been qualitative and dependent upon vendor application specialists. This study aimed to propose a systematic approach for grayscale imaging preset optimization and apply the approach in a clinical abdominal scan setting.

Methods

A six‐step approach was detailed including identification of clinical task, adjustment of basic parameters, fine‐tuning of advanced parameters, image performance metrics confirmation, clinical evaluation and data analysis, and implementation of new presets and monitoring of clinical usage. Its application in an abdominal scanning task was described for each step with phantoms, volunteers, and software tools.

Results

Clinical image data analytics facilitated the understanding of the imaging task, relevant transducers, and target characteristics, in addition to specific requests from radiologists. Quantitative measurements were made on global image contrast and gray map function. In addition, clinically relevant phantoms and volunteer scans without and with acoustic distortion layers were involved to determine the new presets. Furthermore, phantom signal to noise ratio study and clinical evaluation using volunteers with different body habitus were utilized to confirm the superiority of the new presets. Quantitative clinical usage monitoring demonstrated successful implementation of the new presets.

Conclusions

A systematic approach for grayscale imaging preset optimization has been proposed and successfully applied for a specific clinical task. This approach was designed to be generalizable and relatively flexible, which would facilitate movement away from previous qualitative and subjective approaches.

Platelets can secrete multiple growth factors for peripheral nerve repair. However, topically injected platelets are rapidly activated followed by burst release of the cargos, causing limited therapeutic efficiency in vivo. Herein, a platelet‐incorporated hydrogel conduit is shown that acts as a biosynthetic nerve conduit for peripheral nerve repair. This conduit is prepared by rapid 3D printing of the live platelets mixed with bio‐ink containing gelatin methacrylate (GelMA) and poly(ethyleneglycol)diacrylate (PEGDA). The hydrogel can significantly prolong the survival of the incorporated platelets. While the conduit provides a physical foundation for bridging the nerve gaps, live platelets in the conduit sustained‐release multiple growth factors to promote the nerve repair. The in vivo therapeutic efficiency of this platelet‐incorporated nerve conduit is tested in bridging a 10 mm gap in sciatic nerves. The results of morphological, electrophysiological, and histological assessments indicate that the incorporated platelets can significantly promote the hydrogel conduits in peripheral nerve repair. The demonstrated 3D bioprinted nerve conduit with live platelets may show potential clinical application in peripheral nerve repair.

Colloidal metal chalcogenide quantum dots (QDs) have excellent quantum efficiency in light–matter interactions and good device stability. However, QDs have been brought to the forefront as viable building blocks in bottom‐up assembling semiconductor devices, the development of QD solar cell (QDSC) is still confronting considerable challenges compared to other QD technologies due to their low performance under natural sunlight, as a consequence of untapped potential from their quantized density‐of‐state and inorganic natures. This report is designed to address this long‐standing challenge by accessing the feasibility of using QDSC for indoor and concentration PV (CPV) applications. This work finds that above bandgap photon energy irradiation of QD solids can generate high densities of excitons via multi‐photon absorption (MPA), and these excitons are not limited to diffuse by Auger recombination up to 1.5 × 1019 cm−3 densities. Based on these findings, a 19.5% (2000 lux indoor light) and an 11.6% efficiency (1.5 Suns) have been facilely realized from ordinary QDSCs (9.55% under 1 Sun). To further illustrate the potential of the MPA in QDSCs, 21.29% efficiency polymer lens CPVs (4.08 Suns) and viable sensor networks powered by indoor QDSCs matrix have been demonstrated.

Herein, the mechanical behaviors of Li10GeP2S12 (LGPS) solid electrolytes during electrochemical cycling using operando X‐ray tomography are investigated. It is demonstrated that the bulk mechanical decomposition of LGPS when cycled against lithium is a direct result of electrochemical reduction of the solid electrolyte at the LGPS/Li0 interface. The reductive decomposition of LGPS during lithium plating results in the formation of low‐density domains at the electrode/electrolyte interface, which impose sufficient mechanical stress on the underlying LGPS to crack the SE pellet. The critical stress developed prior to pellet fracture is significantly lower than the bulk shear modulus of LGPS, suggesting that the electrochemical instability of LGPS dramatically worsens the mechanical stability of the material near the LGPS/Li0 interface. It is also shown that the application of a highly concentrated liquid electrolyte to the LGPS surface suppresses the reductive decomposition of LGPS, improving both the electrochemical performance and mechanical stability of the bulk LGPS solid electrolyte.

Sodium‐ion batteries have attracted ever‐increasing attention in view of the natural abundance of sodium resources. Sluggish sodiation kinetics, nevertheless, remain a tough challenge, in terms of achieving high rate capability and high energy density. Herein, a sheet‐in‐sphere nanoconfiguration of 2D titania–carbon superlattices vertically aligned inside of mesoporous TiO2@C hollow nanospheres is constructed. In such a design, the ultrathin 2D superlattices consist of ordered alternating monolayers of titania and carbon, enabling interpenetrating pathways for rapid transport of electrons and Na+ ions as well as a 2D heterointerface for Na+ storage. Kinetics analysis discloses that the combination of 2D heterointerface and mesoporosity results an intercalation pseudocapacitive charge storage mechanism, which triggers ultrafast sodiation kinetics. In situ transmission electron microscope imaging and in situ synchrotron X‐ray diffraction techniques elucidate that the sheet‐in‐sphere architecture can maintain robust mechanical and crystallographic structural stability, resulting an extraordinary high rate capability, remarkable stable cycling with a low capacity fading ratio of 0.04% per cycle over 500 cycles at 0.2 C, and exceptionally long‐term cyclability up to 20 000 cycles at 50 C. This study offers a method for the realization of a high power density and long‐term cyclability battery by designing of a hierarchical nanoarchitecture.
Survival analysis of farm bankruptcy filings: Evaluating the time to completion of chapter 12 bankruptcy cases

We examine trends in bankruptcy completion times and financial characteristics for farmers filing for chapter 12 bankruptcy after it became a permanent fixture in bankruptcy law to assess justifications for the recently enacted Family Farmer Bankruptcy Clarification Act of 2017 and Family Farmer Relief Act of 2019. Since 2007, chapter 12 filers have seen noticeable increases in their debt levels whereas alternative business bankruptcies have either stagnated or declined in their debt. Using survival analysis methods to correct for the censored nature of open cases, we find that the average time to completion has consistently been longer for chapter 12 than the comparable chapters (7, 11, and 13) of business bankruptcies. Although chapter 12 completion times have not been increasing over time, we find that chapter 7 and 11 completion times have been declining over time for comparable businesses and that debt levels are a significant factor in increased completion times. Our results are consistent with claims that farmers have had rising debt levels in comparison to similar businesses filing for bankruptcy and provide evidence that farmers with increasing debt have had a more difficult time restructuring through chapter 12.
