Published: October 2020

The performance of high-operating-temperature (HOT) longwavelength infrared (LWIR) HgCdTe avalanche photodiodes (APDs) is significantly limited by the increasing dark current related to temperature. In this paper, a novel barrier-blocking LWIR pBp-APD structure is proposed and studied, and the results show that the dark current of pBp-APD is significantly restricted compared with conventional APD without sacrificing the gain at high temperature. Furthermore, the reduction of avalanche dark current is found to be the key points of the significant suppression of dark current. The physical essence of this reduction is revealed to be the depletion of carriers in the absorption region, and the feasibility of the improved structure is further confirmed by the analysis of its energy band and electric field distribution. In addition, the reduction of gain-normalized dark current (GNDC) does not need to sacrifice the gain. The proposed LWIR pBp-APD paves the way for development of high operation temperature infrared APDs.

Published: October 2020

In the quest for a more compact and cheaper Raman sensor, photonic integration and plasmonic enhancement are central. Nanoplasmonic slot waveguides exhibit the benefits of SERS substrates while being compatible with photonic integration and mass-scale (CMOS) fabrication. A difficulty in pursuing further integration of the Raman sensor with lasers, spectral filters, spectrometers and interconnecting waveguides lies in the presence of a photon background generated by the excitation laser field in any dielectric waveguide constituting those elements. Here, we show this problem can be mitigated by using a multi-mode interferometer and a nanoplasmonic slot waveguide operated in back-reflection to greatly suppress the excitation field behind the sensor while inducing very little photon background.
Single-pixel imaging using a recurrent neural network combined with convolutional layers
Authors: Hoshi Ikuo , Shimobaba Tomoyoshi , Kakue Takashi , Ito Tomoyoshi
Published: October 2020

Single-pixel imaging allows for high-speed imaging, miniaturization of optical systems, and imaging over a broad wavelength range, which is difficult by conventional imaging sensors, such as pixel arrays. However, a challenge in single-pixel imaging is low image quality in the presence of undersampling. Deep learning is an effective method for solving this challenge; however, a large amount of memory is required for the internal parameters. In this study, we propose single-pixel imaging based on a recurrent neural network. The proposed approach succeeds in reducing the internal parameters, reconstructing images with higher quality, and showing robustness to noise.
Multifunctional and multichannel all-optical logic gates based on the in-plane coherent control of localized surface plasmons
Authors: Zhu Zebin , Yuan Jing , Jiang Liyong
Published: October 2020

In this Letter, we report a scheme to design multifunctional and multichannel all-optical logic gates based on the in-plane coherent control of localized surface plasmons in an Au nanorod (NR) array on the Si substrate. By using theoretical analysis and structural optimization, we numerically demonstrate a four-channel all-optical logic gate device that can switch three basic logic operations on each NR only by controlling the phase differences of incident beams. This device is ultra-compact in size and shows high extensibility for parallel logic operations, which may be applied in future high-speed on-chip integrated optical computing.

Published: October 2020

Color-rendering manipulation of solar cells is drawing increasing interest, since the integration of color displaying can promote various advanced applications. However, the dual functionality of high-performance operation and easy processing remain a challenge. Here we propose a colorful perovskite solar cell (PSC) based on purely planar layers. The photonic crystal (PC), which does not interfere with the PSC processing, enables the display of high-purity colors and maintaining the number of PC layers at 4–6. The fabricated PSC with a four-layer PC successfully displays red-green-blue (RGB) colors, with the power-conversion efficiency of 10.94%, 11.01%, and 13.70%, respectively. Further study indicates that by employing a six-layer PC the PSC can obtain excellent color-displaying effect with the color gamut up to 81.8% of the standard RGB. It also shows that the design has a good tolerance to the deviation of layer thickness.
Do stays abroad increase intercultural and general competences, affecting employability?
Authors: Genkova Petia , Kruse Lisa
Published: October 2020

With a globalized and growing world market, companies and educational institutions are getting more and more ambitious to re-orient their work patterns to the international level. Universities reacted to the demands of the globalized economy for flexibility and adaptability by the internationalization of their study programs. Research question: Do stays abroad and therefore intercultural experiences of students actually promote occupational competences and personal development? Design: In order to investigate this relationship, an online survey was employed, and a sample of N = 367 students, who had spent at least one semester abroad before, was recruited. The questions were aimed at measuring characteristics of the participants’ stays abroad, as well as occupational engagement, resilience, intercultural competence personality characteristics related to job performance. Results: The findings suggest that experience abroad can partly enhance employability by serving as an additional job qualification. The results reveal that people who have experienced a stay abroad show higher work and study commitment and are more ambitious regarding their work. Furthermore, people with experience abroad show higher levels of resilience. They are more active concerning problem solving and have higher abilities to maintain emotional distance to work. Additionally, people show the more cultural intelligence the longer they stay abroad. Regarding the manifestation of cultural intelligence, the contact quality with the host country nationals played a significant role. It was evinced that higher contact quality is associated with higher values of cultural intelligence. Regarding occupational performance capacity, the results highlight that participants with a stay abroad are more dominant in an occupational context, i.e., they are more oriented towards superiority above others. Value: The present study contributes to the understanding of relevant personal skills and characteristics in intercultural contexts and of how personality might affect the process of becoming more competent. By demonstrating that stays abroad can increase certain work-related competences for students this study indicates that companies and educational institutions should spend more recourses on fostering experiences abroad of students and workers, in order to stay in tune with the requirements of globalization.
La intuición, el programa dialéctico de la República y su práctica en el Parménides y el Teeteto
Authors: Campos Álvaro Vallejo
Published: October 2020

This article examines the relation between the dialectical program established in Plato’s Republic and the practice of dialectic in other dialogues, such as the Parmenides and the Theaetetus. The author argues against those scholars who have sustained a sharp distinction between an intuitive (not discursive) conception of knowledge and the discursive practices characteristic of Plato’s concept of dialectic. In his view, Plato has been overinterpreted from the modern perspective of the distinction between intuitive and discursive forms of knowledge. As a consequence, this article also examines the relation between the dialectical practices displayed in the Parmenides and the Theaetetus and the anhypothetical condition that Plato attributes to “the principle of everything” in the Republic.
Is wisdom courage? A critical dissection of Plat. Prot. 349d2-351b2
Authors: Molinelli Sebastiano
Published: October 2020

In Plat. Prot. 349d2-351b2, first Socrates leads Protagoras to acknowledge that wisdom and courage are the same thing, then Protagoras accuses him of having put in his mouth words that he never said. Starting from a new reconstruction of the logic of Socrates’ demonstration, I will show how this is more complex, sophistic, and corresponding to Protagoras’ accusation than what is usually believed.
John Sallis, Ed. 2017. Plato’s Statesman: Dialectic, Myth, and Politics. Albany: SUNY. 326pp.
Authors: Cliff Romeo Domdii
Published: October 2020

The collected volume Plato’s Statesman: Dialectic, Myth, and Politics presents some of the new interesting research being conducted on the Statesman. The volume is edited by John Sallis who is well known for his work in phenomenology, including writings on such authors as Jacques Derrida, Martin Heidegger, Friedrich Nietzsche and Immanuel Kant, and he has a continental approach to reading Plato. The new research on the Statesman will proceed by ways of the following three points in the collected volume. We will look at the new trend among scholars to read into the Statesman the complete rejection of the existence of an ideal statesman in our contemporary society. Further, we will discuss the unexplored terrains in the dialogue scholars are gravitating to. And finally, we will comment on the fact that all contributors in the volume show a certain degree of sensitivity to the dramatic context of the dialogue and refrain from attributing Plato’s voice to a single character. A brief remark on an aspect of these points will be furnished at the end.
Las amenazas y la simpatía hacia candidatos autoritarios: evidencia de Perú
Authors: Maldonado Arturo
Published: October 2020

Este artículo evalúa si la relación entre las predisposiciones autoritarias y la simpatía por candidatos autoritarios se amplifica en presencia de amenazas económicas o por la delincuencia y el crimen. El análisis se realiza sobre datos de una encuesta aplicada después de la primera vuelta de la última elección presidencial de 2016 en Perú que incluye la simpatía hacia tres candidatos: Keiko Fujimori, percibida como autoritaria, y Pedro Pablo Kuczynski y Verónika Mendoza, considerados como no autoritarios. El instrumento incluyó un experimento de viñetas con noticias sobre economía y delincuencia, fraseadas de tal manera que enfatizaran las amenazas sobre estos temas. En esta encuesta también se midió el autoritarismo individual a través de las actitudes hacia la crianza de los niños. Los resultados indican que los ciudadanos más autoritarios, en situaciones de amenaza, sobre todo económica, manifiestan una mejor valoración de una candidata autoritaria como Keiko Fujimori. Este efecto no se detecta para los candidatos no autoritarios que competían en estas mismas elecciones.
Apprendre aux étudiants paramédicaux à collaborer : dynamique et continuum de pratiques collaboratives dans un dispositif de formation
Authors: Boujard Servane , Le Faou Yann , Guirimand Nicolas
Published: October 2020

L’évolution des besoins en santé nécessite, pour une population donnée, d’améliorer la collaboration entre les différents professionnels des domaines sanitaire et médico-social. Cela demande de repenser les formations initiales en santé pour permettre aux jeunes professionnels de s’adapter à ces nouvelles pratiques de terrain. C’est pourquoi, l’Institut de Formation en Pédicurie-podologie, Ergothérapie et Kinésithérapie (IFPEK) de Rennes a mis en place un dispositif de formation à la collaboration interprofessionnelle. La présente recherche analyse l’effet de ce dispositif sur la professionnalité émergente de 181 étudiants pédicure-podologues, ergothérapeutes et kinésithérapeutes, notamment dans leur capacité à mettre en place des interactions interprofessionnelles dans le cadre d’un travail collaboratif. Dix entretiens semi-directifs auprès de ces étudiants ainsi que des observations directes lors de la formation ont été menés. En s’appuyant sur le modèle canadien du « Continuum des pratiques de collaboration en santé et service sociaux », les résultats montrent qu’une grande majorité des étudiants s’orientent spontanément vers des pratiques collaboratives mais que leurs interactions sont parfois insuffisantes pour répondre aux problématiques de santé les plus complexes.

L’évaluation par les pairs favoriserait l’utilisation de stratégies d’autorégulation chez les apprenants. Cette étude exploratoire visait à examiner l’activité d’étudiants lors d’un dispositif de formation alliant l’évaluation par les pairs et le feedback vidéo en cours de langue dans l’enseignement supérieur. Une analyse du discours suite aux entretiens d’autoconfrontation a révélé l’utilisation de stratégies d’autorégulation et de stratégies de régulation par partage social. Ces résultats préliminaires indiquent un fort potentiel pour des dispositifs de formation basés sur un feedback vidéo en conjonction avec une évaluation par les pairs et un apprentissage collaboratif afin de développer la métacognition chez les apprenants de langues étrangères.
Po Mannie i Viscontim. Śmierć w Wenecji we współczesnej literaturze polskiej, rosyjskiej i ukraińskiej
Authors: Siemońska Olga
Published: October 2020

The article analyzes three pieces of Russian, Ukrainian and Polish contemporary literature on the subject of “the death in Venice”. The authors of the works, by referring to the literary tradition, consciously strengthen the myth of the "the city of death". In their interpretations this myth has two dimensions: the general and the individual. In the general dimension the vision of a dying beauty and fading power encourages reflection on the transitory nature of civilization. The individual dimension is based on the sense of identification of a dying character with a "dying" city, i.e. Venice.

Manaraga – Władimir Sorokin i ostateczna dekonstrukcja tradycji literackiej
Authors: Łaniewski Paweł
Published: October 2020

The deconstruction of the literary tradition is one of the most frequently used postmodern motifs. It is the main point of many works of Russian postmodernists. Due to the exceptional achievements of Russian writers and the considerable influence on forming social consciousness their activity is subject to critical analysis in many works of all waves of Russian postmodernism. In this context Vladimir Sorokin's texts make their mark – for many of them the deconstruction of literary tradition and hermeneutics is a defining category.

Dimensionality reduction for EEG-based sleep stage detection: comparison of autoencoders, principal component analysis and factor analysis
Authors: Tăuţan Alexandra-Maria , Rossi Alessandro C. , de Francisco Ruben , Ionescu Bogdan
Published: October 2020

Methods developed for automatic sleep stage detection make use of large amounts of data in the form of polysomnographic (PSG) recordings to build predictive models. In this study, we investigate the effect of several dimensionality reduction techniques, i.e., principal component analysis (PCA), factor analysis (FA), and autoencoders (AE) on common classifiers, e.g., random forests (RF), multilayer perceptron (MLP), long-short term memory (LSTM) networks, for automated sleep stage detection. Experimental testing is carried out on the MGH Dataset provided in the “You Snooze, You Win: The PhysioNet/Computing in Cardiology Challenge 2018”. The signals used as input are the six available (EEG) electoencephalographic channels and combinations with the other PSG signals provided: ECG – electrocardiogram, EMG – electromyogram, respiration based signals – respiratory efforts and airflow. We observe that a similar or improved accuracy is obtained in most cases when using all dimensionality reduction techniques, which is a promising result as it allows to reduce the computational load while maintaining performance and in some cases also improves the accuracy of automated sleep stage detection. In our study, using autoencoders for dimensionality reduction maintains the performance of the model, while using PCA and FA the accuracy of the models is in most cases improved.
Zwischen Putin und Trump:Orbáns illiberale Demokratie und das Spektakel des Sports in Ostmitteleuropa
Authors: Kalmar Ivan
Published: October 2020

Wie schaffen es illiberale Politiker, mit einer Politik gewählt zu werden, die gegen die Interessen ihrer Wähler verstößt? Eine mögliche Antwort ist, dass sie Spektakel als Ersatz für Debatten und politische Auseinandersetzung bieten. Mit den Arbeiten von Roland Barthes zu Mythologie und von Guy Debords zu Spektakeln argumentiere ich, dass für illiberale Führungsspitzen wie Putin, Trump und Orbán das Spektakel des Sports dazu dient, die Debattenkultur in der praktischen Politik zu übertünchen. Orbáns Variante dieser Spektakel ist von besonderem Interesse für den europäischen Kontext, da sie aufzeigt, wie die illiberale Beseitigung einer Debattenkultur innerhalb der Regelwerke und Vorgaben der Europäischen Union möglich wird.
Analysis of pore throat characteristics of tight sandstone reservoirs

Published: October 2020

The characterization of pore throat structure in tight reservoirs is the basis for the effective development of tight oil. In order to effectively characterize the pore -throat structure of tight sandstone in E Basin, China, this study used high-pressure mercury intrusion (HPMI) testing technology and thin section (TS) technology to jointly explore the characteristics of tight oil pore throat structure. The results of the TS test show that there are many types of pores in the tight sandstone, mainly the primary intergranular pores, dissolved pores, and microfractures. Based on the pore throat parameters obtained by HPMI experiments, the pore throat radius of tight sandstone is between 0.0035 and 2.6158 µm. There are two peaks in the pore throat distribution curve, indicating that the tight sandstone contains at least two types of pores. This is consistent with the results of the TS experiments. In addition, based on the fractal theory and obtained capillary pressure curve by HPMI experiments, the fractal characteristics of tight sandstone pore throat are quantitatively characterized. The results show that the tight sandstones in E Basin have piecewise fractal (multifractal) features. The segmentation fractal feature occurs at a pore throat radius of approximately 0.06 µm. Therefore, according to the fractal characteristics, the tight sandstone pore throat of the study block is divided into macropores (pore throat radius > 0.06 µm) and micropores (pore throat radius < 0.06 µm). The fractal dimension D
L of the macropores is larger than the fractal dimension D
S of the micropores, indicating that the surface of the macropores is rough and the pores are irregular. This study cannot only provide certain support for characterizing the size of tight oil pore throat, but also plays an inspiring role in understanding the tight pore structure of tight sandstone.
Effects of igneous intrusions on source rock in the early diagenetic stage: A case study on Beipiao Formation in Jinyang Basin, Northeast China
Authors: Sun Shouliang , Zhang Tao , Li Yongfei , Chen Shuwang , Sun Qiushi
Published: October 2020

Mesozoic intrusive bodies play an important role in the temperature history and hydrocarbon maturation of the Jinyang Basin in northeastern China. The Beipiao Formation, which is the main source rock in Jinyang Basin, was intruded by numerous igneous bodies and dykes in many areas. The effects of igneous intrusive bodies on thermal evolution and hydrocarbon generation and migration in the Beipiao Formation were investigated. A series of samples from the outcrop near the intrusive body were analyzed for vitrinite reflectance (R
0%) and other organic geochemical parameters to evaluate the lateral extension of the thermal aureole. The R
0 values of the samples increase from a background value of ∼0.9% at a distance above 200 m from the intrusive body to more than 2.0% at the vicinity of the contact zone. The width of the altered zone is equal to the thickness of the intrusive body outcropped in the field. Organic geochemical proxies also indicate the intrusive body plays a positive and beneficial role in the formation of regional oil and gas resources. Due to the influence of the anomalous heat from the intrusive body, the hydrocarbon conversion rate of the source rocks of the Beipiao Formation was significantly improved. The accumulation properties and the storage capacity of the shales also greatly improved due to the intrusive body as indicated by the free hydrocarbon migration in the shales. This new understanding not only provides a reliable scientific basis for the accurate assessment of oil and gas genesis and resources in the Jinyang Basin but also provides guidance and reference for oil and gas exploration in the similar type of basin.

Published: October 2020

CaO–MgO–Al2O3–SiO2 glass-ceramics with diopside as the main crystalline phase were prepared by melting blast furnace slag obtained from Baotou Iron and Steel Company. The effect of heat treatment on the crystallization behavior of glass-ceramics, containing a large proportion of melted blast furnace slag, was studied by means of differential thermal analysis and scanning electron microscopy. The optimum heat-treatment regime was obtained by orthogonal experimental results for glass-ceramics in which blast furnace slag comprised 70% of the composition and 1% Cr2O3 and 4% TiO2 were used as nucleating agents. The nucleation temperature was 750°C for 2.5 h and the crystallization temperature was 930°C for 1 h. Under this regime, the performance of the glass-ceramic was better than that of other groups in the orthogonal experiment.
Parametric models for combined failure time data from an incident cohort study and a prevalent cohort study with follow-up
Authors: McVittie James , Wolfson David , Stephens David , Addona Vittorio , Buckeridge David
Published: October 2020

A classical problem in survival analysis is to estimate the failure time distribution from right-censored observations obtained from an incident cohort study. Frequently, however, failure time data comprise two independent samples, one from an incident cohort study and the other from a prevalent cohort study with follow-up, which is known to produce length-biased observed failure times. There are drawbacks to each of these two types of study when viewed separately. We address two main questions here: (i) Can our statistical inference be enhanced by combining data from an incident cohort study with data from a prevalent cohort study with follow-up? (ii) What statistical methods are appropriate for these combined data? The theory we develop to address these questions is based on a parametrically defined failure time distribution and is supported by simulations. We apply our methods to estimate the duration of hospital stays.
Operator focus in discourse and grammar: The two perfectives in Kakabe
Authors: Vydrina Alexandra
Published: October 2020

This study investigates how focus on a TAM and polarity value, known in the literature as operator (Dik 1989, Watters 2010) or auxiliary focus (Hyman & Watters 1984), is manifested in natural speech in Kakabe, a Mande language. I show that the opposition between the two perfective auxiliaries attested in Kakabe is best analyzed in terms of operator focus and therefore extend this notion to Mande languages for the first time. This study analyzes operator focus on the perfective in natural speech. It leads to the discovery of new contexts relevant for the description of focused perfectives, such as performative speech acts and utterances with mental state predicates. Finally, I propose a new approach to the distribution of inflectional markers in narratives, based on an account of the main story line as structured by one overarching Question under Discussion.
“We have a grandios saison gespielt” – English as a lingua franca in media sports interviews
Authors: Wilton Antje
Published: October 2020

This paper presents a study investigating the use of English as a lingua franca (ELF) in media interviews of a specific kind: the focus is on post-match interviews with football (soccer) players. Professional football with its dynamic and fluctuating transfer market is increasingly internationalised and thoroughly mediatised, frequently requiring athletes and journalists to use English when interacting in front of the camera for the benefit of the media audience. The study is based on a small corpus of videos and transcripts of post-match interviews conducted with German football players in English. It uses a conversation analytic approach to explore the mutual influence of language use and genre characteristics on a structural, linguistic, interactional and media level. Post-match interviews are a dialogic media genre with distinctive features that contribute to the genre’s essential functions of reporting, evaluating and collectivising, and differentiate it from other types of interview such as the political, the news or the expert interview. The paper will illustrate and discuss how communicative, interactional and linguistic strategies are employed by participants to master the challenges of a specific type of ELF institutional, media and professional interaction.
Characterization and outcome of 11 children with non-diabetic ketoacidosis
Authors: Abdelkreem Elsayed , Magdy Rofaida M. , Sadek Abdelrahim A.
Published: October 2020

Objectives

To study the clinical and laboratory features, management, and outcome of pediatric non-diabetic ketoacidosis (NDKA).

Methods

Between May 2018 and April 2020, we prospectively collected children under 18 years who presented with ketoacidosis, defined as ketosis (urinary ketones ≥++ and/or serum β-hydroxybutyrate level ≥3 mmol/L) and metabolic acidosis (pH <7.3 and HCO3
− <15 mmol/L). Children with HbA1c level ≥6.5% at initial presentation and those meeting the diagnostic criteria for DM during follow-up were excluded. Data were collected on demographics, clinical and laboratory features, management, and outcome.

Results

Eleven children with 19 episodes of NDKA were identified. The median age was 12 months (range from 5 months to 5 years). They manifested dehydration and disturbed conscious level (all cases), convulsions (n=6), hypoglycemia (n=6), hyperglycemia (n=2) and significant hyperammonemia (n=4). Most cases required intensive care management. Death or neurodevelopmental impairment occurred in six cases. Seven cases had inborn errors of metabolism (IEMs). Other cases were attributed to starvation, sepsis, and salicylate intoxication.

Conclusions

This is the largest case series of pediatric NDKA. Ketoacidosis, even with hyperglycemia, is not always secondary to diabetes mellitus. IEMs may constitute a significant portion of pediatric NDKA. Increased awareness of this unfamiliar condition is important for prompt diagnosis, timely management, and better outcome.
Distance from the endocrinology clinic and diabetes control in a rural pediatric population
Authors: LePage Ana K. , Wise J. Benjamin , Bell Jennifer J. , Tumin Dmitry , Smith Aimee W.
Published: October 2020

Objective

We analyzed the impact of geographic distance from the clinic on adherence to recommended clinic visits and diabetes control among patients with type 1 diabetes (T1D) seen in a pediatric endocrinology clinic serving a rural region in eastern North Carolina.

Methods

We retrospectively included patients with T1D age ≤20 years seen in our clinic during 2017. Outcomes were tracked until June 2018. Distance from the clinic was determined according to the zone improvement plan (ZIP) code of patient address. Visit adherence was defined based on the number of attended visits during the study period, aiming for 1 every 3 months. Glycated hemoglobin (HbA1c) was measured at the first and last visits during the review period

Results

The analysis included 368 patients, of whom 218 (59%) completed at least 1 visit every 3 months. The median HbA1c was 9.1 (interquartile range [IQR]: 8.0, 10.3) at the initial visit, and 9.3 (IQR: 8.0, 11.1) at the final visit. Median distance from the clinic was 56 km (IQR: 35, 86). On multivariable logistic regression, greater distance from the clinic was associated with lower odds of visit adherence (odds ratio per 10 km: 0.93; 95% confidence interval: 0.87, 0.99; p=0.030). Neither distance to the clinic nor clinic visit adherence were associated with HbA1c.

Conclusions

Patients living further away from the clinic were less likely to adhere to the recommended visit schedule, but distance was not correlated with HbA1c levels. Further work is needed to assist families living far from the clinic with adhering to recommended visits.
Assessing disparities in barriers to attending pediatric diabetes camp
Authors: Ferrari Gina E , Valenzuela Jessica M , Wolf Risa M
Published: October 2020

Objectives

While the benefits of diabetes camp programs are well established, minority youth are underrepresented in camp attendance. No research to date has explored barriers to camp attendance or potential disparities in those barriers. Further, little is known about sources families prioritize in seeking diabetes information and support.

Methods

This was a prospective survey of families of children with type 1 diabetes (T1D) using convenience sampling during normally-scheduled clinic visits. Thirty-nine children and their caregivers completed the survey. Results were analyzed for prevalence and mean number of reported barriers, benefits, and diabetes information networks.

Results

Age range was 5–15 years and mean duration of diabetes was 2.9 years (0.4–9y). The most prevalent barriers were location, cost, and concern about sending children to overnight camp. Caregivers had high level of knowledge of camp benefits. Participants reported engaging with the diabetes community through interactions with their diabetes team, Facebook groups, and the JDRF.

Conclusion

Increasing awareness, transportation assistance, and scholarship funding all may increase accessibility of diabetes camps. Diabetes clinic and online or social media groups are both acceptable means of disseminating information about diabetes camp. Further research is indicated to verify if these results are applicable to the larger diabetes community.
Non-adherence to labor guidelines in cesarean sections done for failed induction and arrest of dilation
Authors: Escobar Christina M. , Grünebaum Amos , Nam Eunice Y. , Olson Amber T. , Anzai Yuzuru , Benedetto-Anzai Maria Teresa , Cheon Teresa , Arslan Alan , McClelland W. Spencer
Published: October 2020

Objectives

In 2014, the American College of Obstetrics and Gynecology published guidelines for diagnosing failed induction of labor (FIOL) and arrest of dilation (AOD) to prevent cesarean delivery (CD). The objectives of this study were to determine the rate of adherence to these guidelines and to compare the association of guideline adherence with physician CD rates and obstetric/neonatal outcomes.

Methods

Retrospective cohort review of singleton primary cesarean deliveries for FIOL and AOD at a single academic institution from 2014 to 2016. Univariate and multivariate analyses were used to compare adherence to the guidelines with physician CD rates and obstetric/neonatal outcomes.

Results

Of the 591 cesarean deliveries in the study, 263 were for failed induction, 328 for AOD and 79% (468/591) were not adherent to the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine (ACOG/SMFM) guidelines. Of the failed inductions, 82% (215/263) and of the AODs 77% (253/328) were not adherent. There was no difference between adherent and non-adherent CDs with regard to maternal characteristics, or obstetric/neonatal outcomes. Duration of oxytocin use after rupture of membranes, dilation at time of CD, and birth weight were statistically higher in adherent CDs. On multivariate linear regression, physician CD rates were inversely correlated with adherence to ACOG/SMFM guidelines (p<0.0001), gestational age (p=0.007), and parity (p=0.003).

Conclusions

Our study shows that physician non-compliance with ACOG guidelines was high. Adherence to these guidelines was associated with lower physician CD rates, without an increase in obstetric or neonatal complications.

Insight into the dynamics of non-Newtonian Casson fluid over a rotating non-uniform surface subject to Coriolis force
Authors: Oke Abayomi S. , Mutuku Winifred N. , Kimathi Mark , Animasaun Isaac L.
Published: October 2020

Casson fluid model is the most accurate mathematical expression for investigating the dynamics of fluids with non-zero plastic dynamic viscosity like that of blood. Despite huge number of published articles on the transport phenomenon, there is no report on the increasing effects of the Coriolis force. This report presents the significance of increasing not only the Coriolis force and reducing plastic dynamic viscosity, but also the Prandtl number and buoyancy forces on the motion of non-Newtonian Casson fluid over the rotating non-uniform surface. The relevant body forces are derived and incorporated into the Navier-Stokes equations to obtain appropriate equations for the flow of Newtonian Casson fluid under the action of Coriolis force. The governing equations are non-dimensionalized using Blasius similarity variables to reduce the nonlinear partial differential equations to nonlinear ordinary differential equations. The resulting system of nonlinear ordinary differential equations is solved using the Runge-Kutta-Gills method with the Shooting technique, and the results depicted graphically. An increase in Coriolis force and non-Newtonian parameter decreases the velocity profile in the x-direction, causes a dual effect on the shear stress, increases the temperature profiles, and increases the velocity profile in the z-direction.

Published: October 2020

This study analyses leadership apologies to gain insights into effective leadership performance from the perspective of apologising. The study explores Obama’s leadership qualities that are projected through his apology discourse mainly the strategies used to construct his apologies and values that emerge from them. The study concluded that leadership should be versatile for a leader to be able to perform efficiently in crucial situations. It is important for a leader to have the ability to blend strategies to display good values to perform the speech act of apology well because in doing so, they will be able to bind themselves in good rapport with their followers which creates unity in the relationship. The significance of the study can be viewed in the potential to reframe apology as an empowering act that can positively impact leaders’ image rather than an act that is viewed as taboo or ineffective for leadership.

Various type of zeolites has been produced based on kaolinite and this study likewise utilized kaolin clay as raw material to synthesis zeolite A. Kaolin was in inactive state, therefore it was transformed to metakaolin through dehydroxylation at 800 °C for 4 h. The metakaolin as a source of silica and alumina was then utilized in the synthesis of zeolite A. After hydrothermal synthesis, the zeolite A was exchanged with different concentration of zinc nitrate solution. Zinc content in ion-exchanged zeolite A, ZnA was determined through AAS to calculate the ion exchange capacity. Higher concentration of zinc nitrate had higher zinc content and higher ion exchange capacity. Zeolite A and zinc-exchanged zeolite A were characterized under SEM, XRD and FTIR. Finally, zeolite A and zinc-exchanged zeolite A was used to investigate the antimicrobial properties against gram-negative bacteria, Escherichia coli and gram-positive bacteria Staphylococcus aureus. There was no antimicrobial activity for zeolite A yet zinc-ion–exchanged zeolite A showed inhibition zones around the samples for both the microorganisms.
Graphic analogies in the imitation of music in literature
Authors: Guijarro Lasheras Rodrigo
Published: October 2020

Music may have a strong influence on literature. Many novels have reflected this by thematizing music in many different ways. However, this engagement can also adopt the form of an imitation or a formal presence that does not actually require the text to say anything about music. This paper aims to explore some aspects of musical imitation in literature that have not been analyzed in depth. Departing from the approach developed by Werner Wolf, I propose a distinction between imitating and imitated elements that applies to any case of study. Furthermore, at the core of this article, I advocate for a fourth dimension that the imitation of music in literature may have and that should be added to word music, formal and structural analogies, and imaginary content analogies. I call this fourth category “graphic analogies.” It implies an imitation whose imitating element is the graphic, written aspect of the linguistic signifier. Finally, this leads to the idea that, in the case of the imitation of music in literature, there is not a necessary correlation between imitating and imitated elements.
Extending the embodied semiotic square: A cultural-semantic analysis of “Follow your Arrow”
Authors: Candel Daniel
Published: October 2020

Pelkey’s anchoring of the semiotic square in embodiment is excellent news for cognitive literary theory, a dynamic field still in search of itself. However, his validation of the square, though theoretically unexceptionable, suffers in the execution, for his interpretation of the country song “Follow your Arrow” is less successful. The present article benefits from Pelkey’s validation as it organizes a tool of cultural-semantic analysis (CS-tool) as a ‘deviant’ semiotic square. The article then shows how this particular semiotic square allows us to analyze the song in terms which build on Pelkey’s analysis, but also arrive at more satisfying results. Where Pelkey sees liberation in the song and the square, the tool uncovers manipulation in the former and closure in the latter. The article then assesses the complementarity of and differences between the two squares: Pelkey works on a local sentence-level through direct implicature, thus following the narrative/authorial voice of the poem. The CS-tool starts from a position of higher abstraction requiring a less defined, but still sufficient and more wide-ranging, three-step implicature. This allows the tool to step back from the song’s authorial voice and uncover its manipulations. The article closes by discussing the deviant features of the present square.
Peirce’s diagrammatic reasoning and the cinema: Image, diagram, and narrative inThe Shape of Water
Authors: Lee Yunhee , Cobley Paul
Published: October 2020

This article aims to examine the relationship between image and narrative by means of Peirce’s first trichotomy of qualisign-sinsign-legisign or, for the purposes of the current argument, image-diagram-metaphor. It is argued that narrative, as an extended metaphor, can be examined in three modes: in the image; schematically, in the imagination; and allegorically or in a thought experiment, through hypothetic interpretation. The article outlines two kinds of diagrammatic reasoning emphasized by Peirce: corollarial deduction in which the image is ‘literally seen’ and the reasoning steps are manifest in its conclusion; and theorematic deduction where the conclusion in a diagram is subject to a hypothesis which transforms the image into something new. Demonstrating the breadth of diagrammatic reasoning with reference to the 2018 film,The Shape of Water, the article seeks to explore how allegory and diagram are mutually cooperative, based on three ontological modes: the expressive, the cognitive, and the symbolic. Its primary focus, then, is not so much on the story events of the narrative, as the way that they are visualized and characterized as the fairy story unfolds. It is suggested that the interpreting activity involved in allegory and diagram ties interpretation to metacognition, ultimately (re)recognizing the image inThe Shape of Waterin an attempt to ascertain the meaning of love.

The surface layer states of a component are of great importance for the application of hard turned parts. Without a multitude of tests and experience, the states cannot be reliably produced due to process-typical disturbance variables such as tool wear and batch inclusions. The aim of this research is to control the surface layer states during cryogenic hard turning of AISI 52100 by feedforward control and the use of a soft sensor. This paper presents the measurement techniques used in this context. On the one hand, the in-process measurement technology and challenges involved are discussed. On the other hand, the challenges in the ex-situ measurement technique for characterizing the surface layer states are shown using micro hardness measurement as an example.

Shared Neural Representations of Cognitive Conflict and Negative Affect in the Medial Frontal Cortex
Authors: Vermeylen Luc , Wisniewski David , González-García Carlos , Hoofs Vincent , Notebaert Wim , Braem Senne
Published: October 2020

Influential theories of Medial Frontal Cortex (MFC) function suggest that the MFC registers cognitive conflict as an aversive signal, but no study directly tested this idea. Instead, recent studies suggested that nonoverlapping regions in the MFC process conflict and affect. In this preregistered human fMRI study (male and female), we used MVPAs to identify which regions respond similarly to conflict and aversive signals. The results reveal that, of all conflict- and value-related regions, only the ventral pre-supplementary motor area (or dorsal anterior cingulate cortex) showed a shared neural pattern response to different conflict and affect tasks. These findings challenge recent conclusions that conflict and affect are processed independently, and provide support for integrative views of MFC function.

SIGNIFICANCE STATEMENTMultiple theories propose that the MFC, and the dorsal ACC in particular, integrates information related to suboptimal outcomes from different psychological domains (e.g., cognitive control and negative affect) with the aim of adaptively steering behavior. In contrast to recent studies in the field, we provide evidence for the idea that cognitive control and negative affect are integrated in the MFC by showing that a classification algorithm trained on discerning cognitive control (conflict vs no conflict) can predict affect (negative vs positive) in the voxel pattern response of the dorsal ACC/pre-SMA.
