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

Abstract
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

AbstractThis 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

AbstractThis 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

Abstract

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

Abstract

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

Abstract

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.

Abstract

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

AbstractCasson 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.
Strategies and Leadership Values in Obama’s Apology Discourse
Authors: Varma Susanna Bithiah , Paramasivam Shamala , Nimehchisalem Vahid 
Published: October 2020

AbstractThis 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.
Ion exchange capacity of zeolite A with zinc nitrate and its antimicrobial activity
Authors: Kartar Singh Harnish Kaur , Amin Zarina , Arshad Sazmal Effendi 
Published: October 2020

Abstract
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

AbstractMusic 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

AbstractPelkey’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

AbstractThis 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.
In-process and ex-situ measurement techniques for the characterization of surface conditions during cryogenic hard turning of AISI 52100

Published: October 2020

Abstract
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.
