Published: September 2020

Due to the complexity of the maxillofacial surgery, the novice should be sufficiently trained before one is qualified to carry on the surgery. To reduce the training costs and improve the training efficiency, a virtual mandible surgical system with haptic feedback is proposed. This surgical simulation system offers users the haptic feedback while simulating maxillofacial surgery. An integrated model is introduced to optimize the system simulation process, which includes force output to a six-degree-of-freedom haptic device. Based on the anatomy structure of the bone tissue, a two-layer mechanism model is designed to balance the requirement of real-time response and the force feedback accuracy. Collision detection, force rendering, and grinding function are studied to simulate some essential operations: open reduction, osteotomy, and palate fixation. The proposed simulation platform can assist in the training and planning of these oral and maxillofacial surgeries. The fast response feature enables surgeons to design a patient-specific guide plate in real-time. Ten stomatology surgeons evaluated this surgical simulation system from the following four indexes: the level of immersion, user-friendliness, stability, and the effect of surgical training. The evaluation score is eight out of ten.
L’Esthétique musicale classique et romantique
Authors: Dahlhaus Carl
Published: September 2020

L’Esthétique musicale classique et romantique (1988), l’ultime ouvrage de Carl Dahlhaus, est une présentation de la réflexion musicale entre l’« époque-seuil » (Kosellek) située autour de 1770 et les décennies tardives du XIXe siècle, qui marquent le début de la modernité. Même s’il traite essentiellement de l’Allemagne, cet ouvrage est universel, dans la mesure où l’esthétique musicale allemande, en particulier durant la décennie décisive ouverte par la Critique de la faculté de juger de Kant (1790) et close par les Fantaisies sur l’art de Ludwig Tieck (1799), a été à la pointe de l’évolution européenne. Le romantisme fut un phénomène d’esthétique musicale avant de devenir un phénomène musical ; il s’affirma comme mode d’écoute avant de pénétrer les styles et les formes de la composition. Parmi les faits les plus curieux de l’époque sur laquelle le livre est centré, figure la simultanéité des esthétiques musicales classique et romantique. Néanmoins, l’esthétique musicale classique demeurait vers 1800 rudimentaire, parce qu’il n’y avait pas de liaison efficace entre Vienne, le lieu du classicisme musical, et le foyer essentiel de développement de la réflexion sur la musique, le centre et le nord de l’Allemagne. À certains égards, le grand critique musical autrichien Eduard Hanslick (†1904), qui a été injustement traité de formaliste, est l’esthéticien qui a réussi à donner une formulation légitime de l’esprit de la musique classique. C’est d’elle que purent partir plus tard, bien que sans le dire, August Halm et Heinrich Schenker.
Skin Preparation and Electrode Replacement to Reduce Alarm Fatigue in a Community Hospital Intensive Care Unit
Authors: Leigher Debbie , Kemppainen Paula , Neyens David M.
Published: September 2020

Background

Nurses in intensive care units are exposed to hundreds of alarms during a shift, and research shows that most alarms are not clinically relevant. Alarm fatigue can occur when a nurse becomes desensitized to alarms. Alarm fatigue can jeopardize patient safety, and adverse alarm events can lead to patients dying.

Objective

To evaluate how a process intervention affects the number of alarms during an 8-hour shift in an intensive care unit.

Methods

A total of 62 patients from an intensive care unit were included in the study; 32 of these patients received the intervention, which included washing the patient’s chest with soap and water and applying new electrocardiography electrodes at the start of a shift. The number of alarms, clinical diagnoses, and demographic variables were collected for each patient. A Poisson regression model was used to evaluate the impact of the intervention on the overall number of clinical alarms during the shift, with no adjustments to the alarm settings or other interventions.

Results

After relevant covariates are controlled for, the results suggest that patients in the intervention group presented significantly fewer alarms than did patients in the control group.

Conclusions

Managing clinical alarms is a main issue in terms of both patient safety and staff workload management. The results of this study demonstrate that a relatively simple process-oriented strategy can decrease the number of alarms.

Published: September 2020

Background

Outcomes in pediatric critical care research are typically selected by the researcher.

Objectives

(1) To identify outcomes prioritized by patients and their families following a critical illness and (2) to determine the overlap between patient-centered and researcher-selected study outcomes.

Methods

An exploratory descriptive qualitative study nested within a longitudinal cohort study conducted in 2 pediatric intensive care units (PICUs). Participants were purposively sampled from the primary cohort to ensure adequate demographic representation. Qualitative descriptive approaches based on naturalistic observation were used to collect data and analyze results. Data were coded by using the International Classification of Functioning, Disability, and Health Children and Youth (ICF-CY) framework.

Results

Twenty-one participants were interviewed a mean of 5.1 months after PICU discharge. Outcomes fell into 2 categories: patient-centered and family-centered. In the former, diagnosis, survival, and prognosis were key priorities during the acute critical illness. Once survival appears possible, functioning (physical, cognitive, and emotional), and factors that influence recovery (ie, rehabilitation, environment, and quality of life) are prioritized. Family-centered outcomes consisted of parents’ psychosocial functioning and experience of care. Patient-centered outcomes were covered well by the selected study measures of functioning, but not by the clinical outcome measures.

Conclusion

Functioning and quality of life are key patient-centered outcomes during recovery from critical illness. These are not well captured by end points typically used in PICU studies. These results justify the importance of patient- and family-centered outcomes in PICU research and a need to determine how these outcomes can be comprehensively measured.
Adherence to the Mediterranean diet model and psoriatic disease (skin, joint and metabolic expression of psoriasis)
Authors: Laurenti Rosita , Gubinelli Emanuela , Teofoli Patrizia , Moretta Gaia , Pallotta Sabatino
Published: September 2020

Psoriasis is a chronic disease, characterized by systemic inflammation with skin, joint and metabolic involvement. The most common tools to evaluate the severity of each disease is respectively the Psoriasis Area Severity Index (PASI) and the Disease Activity Index for Psoriatic Arthritis (DAPSA). The association between psoriasis and obesity and the role of visceral fat in producing an inflammatory state have been demonstrated. The Mediterranean Diet (MD) has been recommended as a model of healthy diet on the basis of scientific evidence and considered as an adjuvant therapy for all patients affected by chronic inflammatory diseases. Our study evaluated the association between adherence to MD (assessed with the Predimed questionnaire) and psoriatic disease severity. 80 patients (40 with psoriasis and 40 with psoriatic arthritis) were evaluated for disease severity (PASI, DAPSA) and were assessed for Metabolic Syndrome according to the International Diabetes Federation (IDF) definition. To evaluate adherence to the MD, each patient was administered the Predimed questionnaire which includes 14 questions. Our study shows a correlation between low adherence to MD and a high expression of psoriasis, considering cutaneous, joint symptoms and the metabolic profile.
Depiction of Shona marriage institution in Zimbabwe local television drama, Wenera Diamonds
Authors: Samanga T. , Matiza V.M.
Published: September 2020

Marriage is a highly celebrated phenomenon among the African people. It is one of the important institutions among the Shona and Ndebele people in Zimbabwe as expressed in the saying ‘musha mukadzi’ and ‘umuzingumama’ (home is made by a woman) respectively. However with the coming of colonialism in Zimbabwe, marriage was not given the appropriate respect it deserves. This has given impetus to this paper where the researchers in the study through drama want to bring out the depiction of marriage institution in a post -independence television drama, Wenera Diamonds (2017). This paper therefore, aims to show the impact of neo-colonialism on Shona marriage institution. The neo colonial period is characterised with the perpetuation of Western imperial interests through protocols of diplomatic relations, treaties and existing bilateral agreements which marked a new phase of relationships with former colonisers. The aim of this article therefore is to depict marriage institution in neo colonial Zimbabwe in Wenera Diamonds (2017), a Zimbabwean television drama. Using qualitative research methodology, the research employs content analysis to elucidate the depiction in the said performance. Guided by the Africana womanist perspective, the article argues that the indigenous knowledge needed for African social development is rendered irrelevant by a dysfunctional set of values of the western hegemony. Against that, the paper establishes that the depiction of marriage institution in Wenera diamonds is a reflection of imperialist colonial forces on the black person hence the need to go back to basics and resuscitate their culture.
The Russian approach to regulating video games: a play-through
Authors: Danshina Ksenia
Published: September 2020

The Russian video game market is one of the world's biggest markets with a total revenue of USD 2 billion in 2019, making it potentially attractive for investors to explore. Although launching a product for the Russian market may require a lot of attention to regulatory details, on many issues the Russian legal environment seems to be favourable to game companies. This is an analysis of a number of typical issues that a game company may face in the Russian market. In particular, the following issues will be considered: the likelihood of success in disputes arising between game companies and gamers or the Russian state; the legal implications of qualifying an in-game asset; and whether the use of loot boxes in a game can lead to the game being qualified as gambling.
Stroke Perception and Response amongst Elderly Persons in Benin, City, Nigeria
Authors: Odiase FE , Kayode-Iyasere E
Published: September 2020

Theories on health behaviour have recognized perceived risk as an essential factor in the adoption of a healthy lifestyle, however, little is known about stroke risk perception and response to stroke in the elderly population of Nigeria. Ageing being the most important unmodifiable risk factor for stroke, this study aims to determine the predictors of perception of stroke risk and response to stroke in the elderly This was a cross-sectional study, which involved a multi-stage random sampling, recruiting one hundred and sixty individuals 65years and older. The interview was by face to face using a questionnaire to determine, demographics, knowledge of stroke risk, perception of stroke risk and response in the event of a stroke. Multiple logistic regression models were used to analyze predictors of dependent variables Only 32.5% of participants had an accurate perception of stroke risk while 30.6% would consider taking a patient to hospital in the event of a stroke. Increasing age (P=0.001), the female gender (P<0.05), having two or more risk factors for stroke (P=0.001) and attending two or more specialized clinics (P=0.001) were significant predictors of the wrong perception of stroke risk and inappropriate response in the event of a stroke. The elderly are at risk for stroke, but sadly with increasing age and additional risk factors for stroke, the majority have a wrong perception of stroke risk and would respond inappropriately in the event of a stroke. It might be necessary to run stroke campaigns that are targeted and appropriate to the elderly, involving continuous intermittent repetitions.
The democratization in fashion and the insertion and acceptance of various styles as a form of influence on major fashion brands and mass consumption
Authors: Rizzo Ana Larissa de Freitas
Published: September 2020

The aim of this paper is to demonstrate how the democratization of fashion currently divides social groups and influences the major brands in their collections. In a society marked by individualization, so that people seek to belong to tribes, there is still space with in the seal ready mentioned tribes, although there is a form of individualized identity. Now the fashion also come from the streets and brings to the runways more crowded creations with influences from the street, a phenomenon called Bubble Up and transforming the fashion scene, once dominated by an elitist team of textile groups who chose what society would want to find in stores and buy no matter what the value of the pieces.

Practice of physical exercises as a non-pharmacological strategy in the treatment of alzheimer's disease treatment
Authors: Doine Mauro Queiroz , Martelli Anderson , Hunger Marcelo Studart
Published: September 2020

Studies show that the life expectancy of the world population is increasing and consequently the elderly population. With aging is observed a loss of cognitive skills that can occur pathologically such as Alzheimer's disease (AD). AD is a neurodegenerative disease characterized by the accumulation of extraneuronal amyloid plaques and intraneuronal neurofibrillar entanglements located in regions of the temporal lobe, which result in progressive cognitive decline. Physical activity programs can reduce the risk of AD development. Thus, this study aimed to portray the pathophysiological aspects of AD, and the practice of physical exercise as a non-pharmacological method in its prevention. The research was carried out from a bibliographic review of specialized literature, being consulted scientific articles located in the databases Medline, Scielo, Lilacs, Google Academic and the portal of CAPES Journals published until 2019 and additionally consultation of academic books to complement the research. Physical exercises can prevent and delay the disease, in addition to physical benefits such as improved psychological state, behavior disorders, improved ability to perform daily life activities, reduced risk of falls and the social relationship of the patient.

Gifting and philanthropy environment in contemporary Kenya : agency and structural determinants
Authors: Mati Jacob
Published: September 2020

Why is giving a ubiquitous human behaviour in Kenya? What shapes Kenyan gifting practices? This paper argues that philanthropic behaviour is a product of multi-directional interactions between individual agency, experiences, and the socio-institutional structures. In Kenya, the socio-institutional structuring results from faith, African philosophical worldviews, the legal environment, and the widespread socioeconomic precariousness. Drawing from existing literature, analysis of legal documents and primary interviews, this paper utilises habitus – durable, transposable dispositions, structured structures and practices – along with Max Weber’s four ideal type rationalities – instrumental, value, affectual and traditional – to explain why the philanthropic landscape in Kenya looks the way it does. It is argued that gifting and philanthropic behaviour is shaped and given form by both individual experiences and the socio-institutional structures within which they emerge.

Evaluation of Stress Corrosion Cracking, Sulfide Stress Cracking, Galvanic-Induced Hydrogen Stress Cracking, and Hydrogen Embrittlement Resistance of Aged UNS N06625 Forged Bars
Authors: Febbrari A. , Montani R. , Veronesi C. , Cavagnola M. , Brognoli E. , Gelfi M. , Pola A.
Published: September 2020

UNS N06625 is a nickel-based superalloy used for oil and gas applications and commonly produced according to NACE MR0175 in the annealed/solution annealed condition. The annealing/solution annealing treatment makes the material corrosion resistant in the most challenging environments, in the presence of sulfides and chlorides at high pressure and temperature. However, thanks to its chemical composition, UNS N06625 can also be considered as an age-hardenable material whose mechanical strength can be improved by promoting the metastable second phase γ′′ precipitation into the γ matrix. However, the corrosion behavior of the aged alloy has never been investigated in NACE environments. This paper aims to understand the suitability of the age-hardened condition of UNS N06625 for oil and gas applications through the evaluation of the material corrosion performance in NACE level VII environments by using NACE TM0177 tests. Three heats of UNS N06625 have been produced and forged in different bar diameters: 152 mm (6 in), 203.2 mm (8 in), and 254 mm (10 in). Afterward, the bars have been annealed and age-hardened according to optimized time-temperature parameters and finally tested to assess their mechanical properties and resistance to stress corrosion cracking, sulfide stress cracking, galvanic-induced hydrogen stress cracking, and hydrogen embrittlement.
Calculating Resonance Angle for Surface Plasmon Resonance Activation on Different Metals
Authors:   University of South Florida, Nguyen Dang
Published: September 2020

Surface plasmon resonance (SPR) is the technique that has been used in many fields including biomedical science, optic, biosensing, photothermal plasmon and medicine. With the help of Kretschmann configuration, the setup allows to excite the electrons located around the metal which results in electron oscillation, also known as the plasmonic effect. However, SPR requires many factors in order to be activated. This paper approaches and analyzes two crucial features, the incident angle of incoming light and the effect of permittivity that different metals have in order to determine the sufficient value for the plasmon to exist. Different metals including gold, silver and iron are used with the dielectric air and water in order to figure out the most applicable metal with its resonance angle.
An influenza pandemic exercise in a major urban setting, Part I: Hospital health systems lessons learned and implications for future planning

Published: September 2020

A 2007 pandemic exercise in Maricopa County, Arizona, the 5th largest urban population in the United States, revealed major vulnerabilities in planning, response, resource utilization, and the decision-making process, which would be common to any large urban setting where multiple independent organizations exist and have not yet coordinated or shared their plans. Communication challenges are both prevalent and magnified in large urban settings. There must be tough, broad-based decision making by healthcare leadership with guidance and processes at every level to assure compliance to the primary goals of pandemic flu plans necessary to control the transmission rate of the disease. A unifying decision-making element such as a Health-related Emergency Operations Center is critical for the coordination, which serves all urban health systems. Education and training in pre-event protocols for triage management is crucial at every level where resources will be scant. This is especially true in admissions to intensive care units and priorities for ventilator use.
Mechanical ventilation in disaster situations: A new paradigm using the AGILITIES Score System
Authors: Wilkens, MD, MPH Eric P. , Klein, MD, MPH, MBA Gary M.
Published: September 2020

Background: The failure of life-critical systems such as mechanical ventilators in the wake of a pandemic or a disaster may result in death, and therefore, state and federal government agencies must have precautions in place to ensure availability, reliability, and predictability through comprehensive preparedness and response plans.Methods: All 50 state emergency preparedness response plans were extensively examined for the attention given to the critically injured and ill patient population during a pandemic or mass casualty event. Public health authorities of each state were contacted as well.Results: Nine of 51 state plans (17.6 percent) included a plan or committee for mechanical ventilation triage and management in a pandemic influenza event. All 51 state plans relied on the Centers for Disease Control and Prevention Flu Surge 2.0 spreadsheet to provide estimates for their influenza planning. In the absence of more specific guidance, the authors have developed and provided guidelines recommended for ventilator triage and the implementation of the AGILITIES Score in the event of a pandemic, mass casualty event, or other catastrophic disaster.Conclusions: The authors present and describe the AGILITIES Score Ventilator Triage System and provide related guidelines to be adopted uniformly by government agencies and hospitals. This scoring system and the set of guidelines are to be used in disaster settings, such as Hurricane Katrina, and are based on three key factors: relative health, duration of time on mechanical ventilation, and patients’ use of resources during a disaster. For any event requiring large numbers of ventilators for patients, the United States is woefully unprepared. The deficiencies in this aspect of preparedness include (1) lack of accountability for physical ventilators, (2) lack of understanding with which healthcare professionals can safely operate these ventilators, (3) lack of understanding from where additional ventilator resources exist, and (4) a triage strategy to provide ventilator support to those patients with the greatest chances of survival.

Published: September 2020

Background: While mass-casualty incidents (MCIs) may have competing absolute definitions, a universally accepted criterion is one that strains locally available resources. In the fall of 2017, a MCI occurred in New York and Bellevue Hospital received multiple injured patients within minutes; lessons learned included the need for a formalized, efficient patient and injury tracking system. Our objective was to create an organized MCI clinical tracking form for civilian trauma centers.Methods: After the MCI, the notes of the surgeon responsible for directing patient triage were analyzed. A succinct, organized template was created that allows MCI directors to track demographics, injuries, interventions, and other important information for hmultiple patients in a real-time fashion. This tool was piloted during a subsequent MCI.Results: In late 2018, the hospital received six patients following another MCI. They arrived within a 4-minute window, with 5 patients being critically injured. Two emergent surgeries and angioembolizations were performed. The tool was used by the MCI director to prioritize and expedite care. All physicians agreed that the tool assisted in organizing diagnostic and therapeutic triage. Conclusions: During MCIs, a streamlined patient tracking template assists with information recall and communication between providers and may allow for expedited care.
Nurses’ perceived emergency preparedness knowledge: An opportunity for improvement
Authors: Bulson, DNP, MPA, RN, NE-BC Julie
Published: September 2020

Objective: This study aimed to provide foundational data supporting the need for nursing education focused on emergency preparedness and response for nursing staff.Design: This study is a cross-sectional, quantitative, descriptive, correlational quality improvement study.Setting: The study location is a Midwest healthcare system comprised of 14 acute care facilities including pediatric and adult level I trauma centers, a burn center, and a fully dedicated pediatric hospital; five long-term care facilities; 230 ambulatory sites; 4,200 employed providers; and a health plan. Participants: A convenience sample of 5,172 currently employed nurses.Main Outcome Measure: The main outcome of this study is the documentation of overall familiarity with emergency preparedness and response knowledge among nursing staff. Logistic ordinal regression statistical analysis was completed to determine the significance of individual domains impacting the overall familiarity score.Results: Findings based on the results of the “overall familiarity with response activities related to a large-scale emergency incident” question documented most staff (78.45 percent) have little or no familiarity with their role in disaster response. Six domains or focused education areas were identified as having a statistically significant impact (p 0.0001 –p = 0.0195) on the results of the overall familiarity question.Conclusions: These study results support the need for more education (academic and/or institutional) related to nursing emergency preparedness and response.
An ankylosaurian dinosaur from the Cenomanian Dunvegan Formation of northeastern British Columbia, Canada
Authors: Arbour Victoria M. , Larson Derek , Vavrek Matthew , Buckley Lisa , Evans David
Published: September 2020

Abstract. Fragmentary but associated dinosaur bones collected in 1930 from
the Pine River of northeastern British Columbia are identified here as
originating from an ankylosaur. The specimen represents only the second
occurrence of dinosaur skeletal material from the Cenomanian Dunvegan
Formation and the first from Dunvegan outcrops in the province of British
Columbia. Nodosaurid ankylosaur footprints are common ichnofossils in the
formation, but the skeletal material described here is too fragmentary to
confidently assign to either a nodosaurid or ankylosaurid ankylosaur. The
Cenomanian is a time of major terrestrial faunal transitions in North
America, but many localities of this age are located in the southern United
States; the discovery of skeletal fossils from the Pine River demonstrates
the potential for the Dunvegan Formation to produce terrestrial vertebrate
fossils that may provide important new data on this significant transitional
period during the Cretaceous.
The importance of management information and soil moisture representation for simulating tillage effects on N2O emissions in LPJmL5.0-tillage
Authors: Lutz Femke , Del Grosso Stephen , Ogle Stephen , Williams Stephen , Minoli Sara , Rolinski Susanne , Heinke Jens , Stoorvogel Jetse J. , Müller Christoph
Published: September 2020

Abstract. No-tillage is often suggested as a strategy to reduce greenhouse gas emissions. Modeling tillage effects on nitrous oxide (N2O) emissions is challenging and subject to great uncertainties as the processes producing the emissions are complex and strongly nonlinear. Previous findings have shown deviations between the LPJmL5.0-tillage model (LPJmL: Lund–Potsdam–Jena managed Land) and results from meta-analysis on global estimates of tillage effects on N2O emissions. Here we tested LPJmL5.0-tillage at four different experimental sites across Europe and the USA to verify whether deviations in N2O emissions under different tillage regimes result from a lack of detailed information on agricultural management, the representation of soil water dynamics or both. Model results were compared to observational data and outputs from field-scale DayCent model simulations. DayCent has been successfully applied for the simulation of N2O emissions and provides a richer database for comparison than noncontinuous measurements at experimental sites. We found that adding information on agricultural management improved the simulation of tillage effects on N2O emissions in LPJmL. We also found that LPJmL overestimated N2O emissions and the effects of no-tillage on N2O emissions, whereas DayCent tended to underestimate the emissions of no-tillage treatments. LPJmL showed a general bias to overestimate soil moisture content. Modifications of hydraulic properties in LPJmL in order to match properties assumed in DayCent, as well as of the parameters related to residue cover, improved the overall simulation of soil water and N2O emissions simulated under tillage and no-tillage separately. However, the effects of no-tillage (shifting from tillage to no-tillage) did not improve. Advancing the current state of information on agricultural management and improvements in soil moisture highlights the potential to improve LPJmL5.0-tillage and global estimates of tillage effects on N2O emissions.
Landslides distribution at tributaries with different evolution stages in Jiangjia Gully, southwestern China
Authors: Tian Xia Fei , Li Yong , Tian Quan Yan
Published: September 2020

Abstract. Landslide susceptibility assessment is of great significance for the disaster prediction and prevention. At present, most studies used statistical methods by the influence factors of landslide distribution, or based on physical models to determine the assessment result, the research of these methods was mainly focused on the gully scale. At the same time, these methods did not focus on the specific principle of material storage. In this paper, the surface erosion index, being the integral of the hypsometric curve, is adopted to explore the landslides distribution characteristic in different tributaries of the gully. Firstly, 81 tributaries of JJG are taken from DEM with 10 m grid cells, and the hypsometric curves are used to characterize their evolution stages; five stages are identified by the evolution index (EI, the integral of the hypsometric curves) and most tributaries are in relative youth stage with EI between 0.5 and 0.6. Then 906 landslides are interpreted from Quickbird satellite image of 0.61 m resolution. It is found that LD (LD = landslides number in a tributary/ the tributary area) increases exponentially with EI, while LAp (LAp = landslides area in a tributary/the tributary area) fluctuates with EI, meaning that landslides are inclined to occur in tributaries with EI between 0.5 and 0.6, and thus these tributaries are the main material sources supplying for debris flows.
Measuring the development and communication of open design communities: The case of the OpenAg Initiative
Authors: Argenton Freire Rodrigo , Ziggiatti Monteiro Evandro
Published: September 2020

Open collaborative development and transparent design processes are often associated to the concept of open design (OD). Studies in remote collaborative processes are still recent and a wide number of aspects of OD remain unclear. This study explores an OD project by mining data in collaboration platforms. As our research object, we selected the Open Agriculture Initiative. Data was mined from its online forum, and Github, a development platform. Social network analysis (SNA) and topic modeling techniques were used to explore four research questions. We comment on these questions highlighting differences between both platforms, stakeholder participation and personal interests, community changes over time, activity volume and latent topics. Finally, we conclude by indicating possible pathways to investigate OD as an emergent phenomenon by using data mining techniques.

To tackle this issue, researchers have developed algorithms to automatically detect non-genuine users, but it is not clear how to identify relevant content, what features to use and how often to retrain classifiers. Users of online discussion boards who informally flag other users by calling them out as paid trolls provide potential labels of perceived propaganda in real time. Against this background, we test the performance of supervised machine learning models (regularized regression and random forests) to predict discussion board comments perceived as propaganda by users of a major Romanian online newspaper. Results show that precision and recall are relatively high and stable, and re-training the model on new labels does not improve prediction diagnostics. Overall, metadata (particularly a low comment rating) are more predictive of perceived propaganda than textual features. The method can be extended to monitor suspicious activity in other online environments, but the results should not be interpreted as detecting actual propaganda.
Where Théophile Gautier Meets Li Yu: Mining Divergence and Common Ground from the “Heying Lou” to “Le Pavillon sur l'eau”
Authors: Bai Yunfei
Published: September 2020

This article traces how the vernacular romance “Heying lou” by Chinese writer Li Yu morphed into Théophile Gautier's novella “Le Pavillon sur l'eau.” The original story, first rendered into English by John Francis Davis under the title “The Shadow in the Water,” was further translated into French by Jean-Pierre Abel Rémusat as “L'Ombre dans l'eau”; it is upon this latter work that Gautier based his “Le Pavillon sur l'eau.” Drawing on a meticulous scrutiny of each author's input into this multilayered transmission, I argue that by artfully rewriting a seventeenth-century Chinese tale centered on polygamy in accordance with late romantic French aesthetics and by foreignizing his prose style, Gautier not only recovered the literary agency of the “Heying Lou” lost in the previous utilitarian translations, but also elevated Rémusat's rendering of the Chinese story from a marginal item in the sinological archive into a well-polished piece of world literature.

Are Level of IL-13 and IL-4 Predictive for Formation of Chronic Inflammation in Children with Asthma?
Authors: Makieieva Nataliia , Malakhova Valeriia , Vasylchenko Yuliia , Tsymbal Valentyn
Published: September 2020

Introduction: Asthma diagnosis in young children may represent a clinical challenge. There are no standard prognostic and dia-gnostic methods. The aim of the study was to evaluate the clinical and prognostic assessment of IL-4 and IL-13 concentrations in children with recurrent wheezing. Material and methods: The study included 96 children with recurrent wheezing. 81 patients were diagnosed as transient wheezing, 15 patients with asthma, and 25 healthy children were selected as controls. The concentrations of IL-4 and IL-13 were analyzed in exhaled breath condensate (EBC) using an enzyme-linked immunosorbent assay (ELISA). Data analysis was performed using Statsoft Statistica Version 8 (Tulsa, OK) and the statistical program MedCalc version 17.2. Results: Both IL-4 and IL-13 concentrations were significantly higher in DDA (21.13 pg/mL, 26.13 pg/mL, respectively) and TW (13.86 pg/mL, 18.3 pg/mL, respectively) groups as compared to healthy controls (3.37 pg/mL, 16.35 pg/mL, respectively; p < 0.001), and the highest rates were observed in children with diagnosed asthma (p < 0.001, DDW vs. TW, respectively). IL-4 concentration higher than 18.45 pg/mL (with sensitivity 86.7% and specificity 80%) and IL-13 concentration higher than 20.17pg/ /mL (with sensitivity 100% and specificity 76.7%) in EBC in children with wheezing recurrence can be considered as a possible predictor of asthma development. Conclusions: The concentration of the anti-inflammatory cytokines IL-4 and IL-13 were significantly increased in children with recurrent wheezing and the highest rates were found in asthma developing children. The concentrations of IL-4 and IL-13 in chil-dren with wheezing can be considered as a possible predictor of asthma development.
The Threshold for Detecting a Rise in Airflow Resistance during Tidal Breathing Is Lower in Older Patients with COPD Than in Healthy People of Similar Age
Authors: Allen Stephen , Tanner Alex , Khattab Ahmed
Published: September 2020

Introduction: To investigate whether or not the threshold for subjectively detecting an increase in the resistance to airflow (LDT) during tidal breathing at rest rises in older age in patients with COPD, as it does in healthy people and asthmatics in remission. Material and methods: We conducted an open cross-sectional study of 31 older patients (age 55–89) with COPD and 60 healthy volunteers (age 55–86). Inspiratory and expiratory resistive load detection thresholds (ILDT and ELDT respectively) and spirometry were measured. Results: The mean (SD) ILDT was 5.93 (7.02) kPa.s/L in COPD patients, compared to 11.11 (8.47) in healthy people (P < 0.001) in the same age range. There was no significant correlation between ILDT and age in the COPD group (r = −0.182, P = 0.326), though significant correlation with age was found in healthy people (r = 0.591, P < 0.001). ILDT and ELDT in COPD patients correlated significantly with the FEV1/FVC ratio (r = 0.367, P = 0.048 and r = 0.481, P = 0.007 respectively) but not with other spirometry indices, height, weight, BMI, oxygen saturation or smoking pack-years. Conclusion: LDT during tidal breathing appears to be sensitized, and thereby lower, in older COPD patients, possibly due to altered central regulation of the threshold or as a consequence of the effect lung compliance, recoil and volume changes have on afferent input from mechano-receptors in COPD. Older COPD patients with good cognition are therefore likely to be as aware of changing airways resistance as younger patients and take appropriate therapeutic action.
ANALYSIS OF THE INFLUENCE OF SHAFT LOAD ON THE VALUE
OF ACCEPTABLE PRELOAD IN A SYSTEM OF ANGULAR BALL
BEARINGS
Authors: KACZOR Jarosław
Published: September 2020

In standard solutions, reactions of the supports and bending moments in bearing shafts are calculated without
taking into consideration the elasticity of the bearings themselves. They are treated as perfectly stiff supports
of articulate character. Whereas, in reality, the majority of bearings do not fulfil conditions of being classified
as joints, because the angular tilt of inner bearing ring in relation to the outer one causes inner elastic
deformations in elements of bearings and the resulting reaction moments. These moments have an impact on
reactions of bearings.
The aim of the research is to determine how shaft loading influences the value of preload by using the criterion
of the durability of the bearing and taking into consideration the elasticity of bearings.
GEOMETRIC AND ENERGETIC CONDITIONS OF METALS’ ABRASIVE WEAR
Authors: SADOWSKI Piotr
Published: September 2020

A new interpretation and a quantitative description of abrasive wear of solids are proposed in this paper.
The well-known J.F. Archard’s dependence, commonly applied by tribologists to describe volume of a worn
material as a function of real contact surface between bodies, serves as the starting point for the discussion.
The dependence characterises adhesive wear whose intensity is restricted to certain energy-conditioned
values. However, greater wear intensities can be observed in abrasive wear. The quantity of energy required
to separate a unit of volume (mass) of a rubbing material is also lower in the case of abrasion than of adhesive
wear. It is claimed, therefore, that the principle of straight proportionality between volumetric wear and real
contact surface of bodies cannot be used to characterise the wear mechanism. The process of detachment of
a worn particle in the form of a chip is related to a certain volume, while the density of the flux of removed
material is related to an apparent machined surface, which is in a specific relation to the nominal contact
surface of rubbing solids. The proposed new physical model and the analytical description of metals’ abrasive
wear are illustrated quantitatively with results of the author’s experiments.
Theoretical Riffs on the Blues
Authors: Colapietro Vincent ,   Semiotic Society of America
Published: September 2020

After disambiguating the word, the author explores the blues primarily not as a genre of music but as a sensibility or orientation toward the world. In doing so, he is taking seriously suggestions made by a host of writers, most notably, Ralph Waldo Ellison, Amiri Baraka, James Baldwin, and Cornel West. As such, the focus is on the blues as an extended family of somatic practices bearing upon expression (or articulation). At the center of these practices, there is in the blues (to modify Foucault’s words) always the patient yet exuberant work of giving articulate form to our impatience for human freedom. But here the distinction between practices of emancipation, by which a people throws off their political domination, and practices of freedom, by which they tirelessly work to make their freed self truly their own, is crucial. In this, the author is guided by an insight provided by Toni Morrison’s Beloved: “Freeing yourself was one thing; claiming ownership of that freed self was another” (1987: 95). As “an art of ambiguity”, the blues turns out to be also an art of ambivalence: the task of claiming ownership of one’s freed self is one demanding, not only learning to live with irreducible ambiguity but also working toward “an achievement of ambivalence”.
