Education for Critical Community and the Pedagogy of Asylum: Two Responses to the Crisis Of University Education
Authors: Koczanowicz Leszek , Włodarczyk Rafał
Published: August 2021

The current heated debate on the deteriorating status of the university raises a range of pertinent questions, including: What role can the humanities play in culture today in the face of the crisis of higher education? To answer this question, the authors begin by problematizing the relationship between culture, the humanities, and education. In the second part of the paper, they examine the changing role of the humanities in conjunction with the understandings of culture, and outline three salient ways in which culture is conceived of today. Subsequently, they focus on the loss of the dominant status that culture suffered when everyday life was discovered in modernity. In the third part, they argue that everyday life, or rather social representations of everyday life and its practices, are currently becoming the chief criterion for assessing culture, the humanities, and education. However, everyday life remains complex both in theoretical conceptualizations and in research observations. For example, everyday life harbors a range of risks and anxieties which are veiled by its own obviousness and reinforced by socialization. The authors conclude that, given this, everyday life in democratic societies calls for the work of understanding, support, affirmation, and criticism, in which the humanities can retain their superior status. In the fourth part, the authors discuss non-consensual democracy, critical community, and the pedagogy of asylum as the forms of organization and action that promote an auspicious interconnection of culture, the humanities, and education.

Published: August 2021

Human DNA methylation profiles have been used successfully to develop highly accurate biomarkers of aging (“epigenetic clocks”). Although these human epigenetic clocks are not immediately applicable to all species of the animal kingdom, the principles underpinning them appear to be conserved even in animals that are evolutionarily far removed from humans. This is exemplified by recent development of epigenetic clocks for mice and other mammalian species. Here, we describe epigenetic clocks for the domestic cat (Felis catus), based on methylation profiles of CpGs with flanking DNA sequences that are highly conserved between multiple mammalian species. Methylation levels of these CpGs are measured using a custom-designed Infinium array (HorvathMammalMethylChip40). From these, we present 3 epigenetic clocks for cats; of which, one applies only to blood samples from cats, while the remaining two dual-species human-cat clocks apply both to cats and humans. We demonstrate that these domestic cat clocks also lead to high age correlations in cheetahs, tigers, and lions. It is expected that these epigenetic clocks for cats possess the potential to be further developed for monitoring feline health as well as being used for identifying and validating anti-aging interventions.

This study involves the histological analysis of samples taken during autopsies in cases of COVID-19 related death to evaluate the inflammatory cytokine response and the tissue localization of the virus in various organs. In all the selected cases, SARS-CoV-2 RT-PCR on swabs collected from the upper (nasopharynx and oropharynx) and/or the lower respiratory (trachea and primary bronchi) tracts were positive. Tissue localization of SARS-CoV-2 was detected using antibodies against the nucleoprotein and the spike protein. Overall, we tested the hypothesis that the overexpression of proinflammatory cytokines plays an important role in the development of COVID-19-associated pneumonia by estimating the expression of multiple cytokines (IL-1β, IL-6, IL-10, IL-15, TNF-α, and MCP-1), inflammatory cells (CD4, CD8, CD20, and CD45), and fibrinogen. Immunohistochemical staining showed that endothelial cells expressed IL-1β in lung samples obtained from the COVID-19 group (p < 0.001). Similarly, alveolar capillary endothelial cells showed strong and diffuse immunoreactivity for IL-6 and IL-15 in the COVID-19 group (p < 0.001). TNF-α showed a higher immunoreactivity in the COVID-19 group than in the control group (p < 0.001). CD8 + T cells where more numerous in the lung samples obtained from the COVID-19 group (p < 0.001). Current evidence suggests that a cytokine storm is the major cause of acute respiratory distress syndrome (ARDS) and multiple organ failure and is consistently linked with fatal outcomes.
Comparison of a new gasless method and the conventional CO2 pneumoperitoneum method in laparoendoscopic single-site cholecystectomy: a prospective randomized clinical trial

Published: August 2021

To avoid CO2pneumoperitoneum-associated cardiopulmonary side-effects during conventional laparoscopic surgeries, we have developed a gasless laparoscopic operation field formation (LOFF) device for laparoendoscopic single-site surgery. The aim of this study is to analyze the safety and efficacy of the LOFF device for laparoendoscopic single-site cholecystectomy and to verify its advantage of avoiding CO2pneumoperitoneum-associated complications. In this prospective, randomized, observer-blinded clinical trial, eligible participants were randomized in a 1:1 ratio to undergo either conventional CO2pneumoperitoneum assisted laparoendoscopic single-site cholecystectomy (LESS) or the new gasless LOFF device assisted laparoendoscopic single-site cholecystectomy (LOFF-LESS). Outcomes including intra-operative respiratory and hemodynamic parameters, operation time, conversion rate, complication rate, et al were compared between the two groups. A total of 100 patients were randomized to the LESS group [n = 50; mean (SD) age, 49.5 (13.9) years; 24 (48.0%) women] and the LOFF-LESS group [n = 50, mean (SD) age, 47.4 (13.3) years; 27 (54.0%) women]. Compared with the LOFF-LESS group, the LESS group witnessed significant fluctuations in intra-operative respiratory and hemodynamic parameters. The tracheal extubation time of the LESS group was significantly longer (P = 0.001). The gasless LOFF device is safe and feasible for simple laparoscopic cholecystectomy and has a predominance of avoiding CO2pneumoperitoneum-associated cardiopulmonary side-effects.

Energy-based performance analysis of a double pass solar air collector integrated to triangular shaped fins
Authors: Machi Maytham H. , Al-Neama Maytham A. , Buzás J. , Farkas I.
Published: August 2021

In this paper, the performance of a double pass solar air collector with triangular integrated fins was investigated experimentally at Hungarian University of Agriculture and Life Sciences in Gödöllő, Hungary. The focus of this research is on energy-based performance evaluation. The thermal efficiency of the collector has been compared by testing two collectors that had the same design, with and without fins. The effect of the collector's air mass flow rate on thermal performance was investigated under various environmental situations. The results revealed that the temperature difference is always higher through the finned collector and the higher variation temperature between the inlet and outlet temperature leads to higher useful heat. The daily thermal efficiency of the finned collector was 56.57%, 59.41%, and 61.42%, while for the un-finned collector was 51.04%, 53.28%, and 57.08% for the mass flow rate 0.0081, 0.0101, and 0.0121 kg/s. The finned double pass solar air collector improved the thermal efficiency by 4.3–6.1% over the un-finned one. The efficiency of the finned collector is always higher than the un-finned one regardless of the mass flow rate. The presence of the fins to the top air channels significantly increases collector efficiency, owing to the increased absorbing surface area, which is responsible for increasing the internal thermal convective exchanges. Moreover, it creates a turbulence airflow, meaning that the air will be in good contact with the absorber plate and penetrate all regions, reducing the dead zones contributing to increased heat transfer.
Cardiovascular Magnetic Resonance (CMR) for the Evaluation of Myocardial Infarction in Patients with Non-obstructive Coronary Artery Disease (MINOCA)
Authors: De Michele F. , Guerra F. S. , Forte V. , Carrieri A. , Chieppa D. R. R. , Guglielmi G.
Published: August 2021

Purpose of Review

Myocardial infarction in the absence of coronary artery disease is caused by a variety of clinical conditions, so it is important to detect the specific causes in order to perform a better prognostic stratification of these patients. The aim of this review is to summarize the most important findings that established the role of CMR (cardiovascular magnetic resonance) to detect the MINOCA (myocardial infarction with non-obstructive arteries) patients and the importance to differentiate them from myocardial infarction patients.

Recent Findings

The role of CMR is crucial to diagnose the principal diseases involved in MINOCA, as demonstrated. The several MR sequences used in all the MINOCA patients showed different results for all the different causes of MINOCA and, surely, high-resolution MR with gadolinium enhancement has been considered the best method to differentiate the transmural lesions.

Another fundamental aspect to be considered is the experience of CMR radiologists, which represent the most important element for the right diagnosis of MINOCA. Surely, in the future, CMR will be the most important technique of choice for MINOCA patients, playing a key role in their management.
Self-Perceived Facial Attractiveness, Fluctuating Asymmetry, and Minor Ailments Predict Mental Health Outcomes
Authors: Borráz-León Javier I. , Rantala Markus J. , Luoto Severi , Krams Indrikis A. , Contreras-Garduño Jorge , Krama Tatjana , Cerda-Molina Ana Lilia
Published: August 2021

Objective

Phenotypic markers associated with developmental stability such as fluctuating asymmetry, facial attractiveness, and reports of minor ailments can also act as indicators of overall physical health. However, few studies have assessed whether these markers might also be cues of mental health. We tested whether self- and other-perceived facial attractiveness, fluctuating asymmetry, and minor ailments are associated with psychopathological symptoms in a mixed sample of 358 college students, controlling for the effects of body mass index, age, and sex.

Methods

We applied the Symptom Checklist-90-Revised (SCL-90-R) questionnaire to assess psychopathological symptoms, a battery of questionnaires about self-perceptions of facial attractiveness, and gathered information about the number of previous minor ailments as well as demographic data. Other-perceived attractiveness was assessed by an independent mixed sample of 109 subjects. Subjects’ facial fluctuating asymmetry was determined by geometric morphometrics.

Results

The results revealed that in both men and women, higher self-perceived attractiveness and fewer minor ailments predicted lower scores of Somatization, Obsessive–Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Phobic Anxiety, Paranoid Ideation, Psychoticism, and a General Psychopathology Index. Higher facial fluctuating asymmetry was associated with higher Interpersonal Sensitivity, but did not contribute to its prediction when controlling for the other studied variables.

Conclusions

The observed strong associations between self-perceived attractiveness, minor ailments, and psychopathology indicate common developmental pathways between physiological and psychological symptomatology which may reflect broader life history (co)variation between genetics, developmental environment, and psychophysiological functioning.
Laser Erasing and Rewriting of Flexible Copper Circuits
Authors: Zhou Xingwen , Guo Wei , Peng Peng
Published: August 2021

Integrating construction and reconstruction of highly conductive structures into one process is of great interest in developing and manufacturing of electronics, but it is quite challenging because these two involve contradictive additive and subtractive processes. In this work, we report an all-laser mask-less processing technology that integrates manufacturing, modifying, and restoring of highly conductive Cu structures. By traveling a focused laser, the Cu patterns can be fabricated on the flexible substrate, while these as-written patterns can be selectively erased by changing the laser to a defocused state. Subsequently, the fresh patterns with identical conductivity and stability can be rewritten by repeating the writing step. Further, this erasing–rewriting process is also capable of repairing failure patterns, such as oxidation and cracking. Owing to the high controllability of this writing–erasing–rewriting process and its excellent reproducibility for conductive structures, it opens a new avenue for rapid healing and prototyping of electronics.
Redefining the Graph Edit Distance
Authors: Serratosa Francesc
Published: August 2021

Graph edit distance has been used since 1983 to compare objects in machine learning when these objects are represented by attributed graphs instead of vectors. In these cases, the graph edit distance is usually applied to deduce a distance between attributed graphs. This distance is defined as the minimum amount of edit operations (deletion, insertion and substitution of nodes and edges) needed to transform a graph into another. Since now, it has been stated that the distance properties have to be applied [(1) non-negativity (2) symmetry (3) identity and (4) triangle inequality] to the involved edit operations in the process of computing the graph edit distance to make the graph edit distance a metric. In this paper, we show that there is no need to impose the triangle inequality in each edit operation. This is an important finding since in pattern recognition applications, the classification ratio usually maximizes in the edit operation combinations (deletion, insertion and substitution of nodes and edges) that the triangle inequality is not fulfilled.
Comparison between single and multiple renal vessels in live donor allograft kidney transplantation: Surgical aspects and outcomes, 25 years experience
Authors: Khattab Alomar Omar Salem
Published: August 2021

ABSTRACT

Background:

The evolving increase in incidence of end stage renal disease in Iraq leading to higher need for live donor kidney transplant that is facing big challenge of live donation shortage which acquire re-evaluation for live donation exclusion criteria.

Aim of study:

To assess whether kidney transplantation using grafts with multiple vessels is associated with higher rate of complications than single vessel.

Patients & methods:

A retrospective cross sectional review study carried at Renal Transplant Center-Medical City teaching hospital and Private Hospitals in Baghdad-Iraq, during the period from 1st of June 1997 to 1st of June 2017 on convenient sample of 2674 live donor transplant patients. The patients were classified first into two groups (single renal vessel vs. multiple renal vessels) and second into four groups: Group A: 1837 grafts with a single artery single anastomosis. Group B: 483 grafts with multiple arteries single anastomosis, Group C-1,2,3: 202 grafts with multiple arteries multiple anastomosis, Group D: 152 grafts with multiple veins multiple anastomosis.

Results:

The vascular reconstruction of renal artery for transplant patients was either single renal vessel (68.7%) or multiple renal vessels (31.3%). No significant differences were observed between transplant patients with single renal vessel and patients with multiple renal vessels regarding survival duration, outcome, graft survival and graft survival duration. There was a highly significant association between younger age transplant patients and single renal vessel graft (p < 0.001).

Conclusions:

The long term outcomes of patients transplanted with single vessel live donor allograft kidney and patients transplanted with multiple vessels live donor allograft kidney are not obviously different.

Lectures on Random Lozenge Tilings
Authors: Gorin Vadim
Published: August 2021

Over the past 25 years, there has been an explosion of interest in the area of random tilings. The first book devoted to the topic, this timely text describes the mathematical theory of tilings. It starts from the most basic questions (which planar domains are tileable?), before discussing advanced topics about the local structure of very large random tessellations. The author explains each feature of random tilings of large domains, discussing several different points of view and leading on to open problems in the field. The book is based on upper-division courses taught to a variety of students but it also serves as a self-contained introduction to the subject. Test your understanding with the exercises provided and discover connections to a wide variety of research areas in mathematics, theoretical physics, and computer science, such as conformal invariance, determinantal point processes, Gibbs measures, high-dimensional random sampling, symmetric functions, and variational problems.
When Computers Dream of Charcoal
Authors: Carter Benjamin P. , Blackadar Jeff H. , Conner Weston L. A.
Published: August 2021

This research employs machine learning (Mask Region-Based Convolutional Neural Networks [Mask R-CNN]) and cluster analysis (Density-based spatial clustering of applications with noise [DBSCAN]) to identify more than 20,000 relict charcoal hearths (RCHs) organized in large “fields” within and around State Game Lands (SGLs) in Pennsylvania. This research has two important threads that we hope will advance the archaeological study of landscapes. The first is the significant historical impact of charcoal production, a poorly understood industry of the late eighteenth to early twentieth century, on the historic and present landscape of the United States. Although this research focuses on charcoal production in Pennsylvania, it has broad application for both identifying and contextualizing historical charcoal production throughout the world and for better understanding modern charcoal production. The second thread is the use of open data, open source, and open access tools to conduct this analysis, as well as the open publication of the resultant data. Not only does this research demonstrate the significance of open access tools and data but the open publication of our code as well as our data allow others to replicate our work, to tweak our code and protocols for their own work, and reuse our results.
On generative models as the basis for digital twins
Authors: Tsialiamanis George , Wagg David J. , Dervilis Nikolaos , Worden Keith
Published: August 2021

A framework is proposed for generative models as a basis fordigital twinsormirrorsof structures. The proposal is based on the premise that deterministic models cannot account for the uncertainty present in most structural modeling applications. Two different types of generative models are considered here. The first is a physics-based model based on the stochastic finite element (SFE) method, which is widely used when modeling structures that have material and loading uncertainties imposed. Such models can be calibrated according to data from the structure and would be expected to outperform any other model if the modeling accurately captures the true underlying physics of the structure. The potential use of SFE models as digital mirrors is illustrated via application to a linear structure with stochastic material properties. For situations where the physical formulation of such models does not suffice, a data-driven framework is proposed, using machine learning and conditional generative adversarial networks (cGANs). The latter algorithm is used to learn the distribution of the quantity of interest in a structure with material nonlinearities and uncertainties. For the examples considered in this work, the data-driven cGANs model outperforms the physics-based approach. Finally, an example is shown where the two methods are coupled such that a hybrid model approach is demonstrated.
Does Power Always Flow to the Executive? Interbranch Oscillations in Legislative Authority, 1976–2014
Authors: Chaisty Paul , Power Timothy
Published: August 2021

Is legislative power flowing to the executive branch over time? Beginning in the 1990s, comparativists began to investigate delegation to the executive under different executive formats. Hypothesized causes include collective action problems due to legislative fractionalization, the presence of a dominant pro-executive faction, preference congruence vis-à-vis the head of government, and challenges posed by economic crises. We test these four hypotheses on a data set containing 2,020 country-year observations of democracies and semi-democracies between 1976 and 2014. Using V-Dem data, we derive annualized measures of shifts in executive–legislative relationships. Contrary to stereotypes of executive dominance, relative gains by legislatures are no less frequent than gains by executives, and economic crises do not advantage political executives in consistent ways. Surprisingly, some of the factors expected to benefit executives seem to enhance assembly authority as well. Robust democracy maintains interbranch power relations in equilibrium, while lower levels of polyarchy are associated with greater ‘noise’ in the relationship.
Effects of shear-thinning rheology on near-wall turbulent structures
Authors: Arosemena Arturo A. , Andersson Ronnie , Andersson Helge I. , Solsvik Jannike
Published: August 2021

Turbulent channel flow simulation of a shear-thinning fluid is considered – see Arosemena et al. (J. Fluid Mech., vol. 908, 2021, p. A43) – and compared with a Newtonian base case to reveal the effects of the shear-dependent rheology on the near-wall structures. Analyses of different flow statistics revealed that, for the shear-thinning fluid case, the streamwise vortices appear to grow in size, depart from the wall and present a lessening in their intensity. Information regarding variations in the quasi-longitudinal vortices is also obtained from three-dimensional structures identified through a normalized $Q$-criterion. With shear-thinning rheology, it is shown that the structures are comprised of wall-attached and -detached families which are taller than for a Newtonian fluid. Also, for a given height, the structures appear to be longer, with approximately the same width and overall larger volume for the shear-thinning fluid case; albeit their fractal dimension remains the same when compared to the Newtonian base case. Moreover, it is observed that the number density of vortical structures decreases with shear-thinning fluid behaviour. These observations, in conjunction with the known changes to the longitudinal velocity structures which appear to be less streaky, more spanwise separated and thickened with shear-thinning rheology, strongly suggest that the near-wall self-sustaining process has been disrupted. As we move slightly away from the wall and with shear-thinning behaviour, the local increase in viscosity seems to lead to less energetic vortices whereas the streaks are provided with an additional source of energy due to fluctuations in viscosity.
Effects of the secondary baroclinic vorticity on the energy cascade in the Richtmyer–Meshkov instability
Authors: Peng Naifu , Yang Yue , Xiao Zuoli
Published: August 2021

We investigate the effect of the secondary baroclinic vorticity (SBV) on the energy cascade in the mixing induced by the multi-mode Richtmyer–Meshkov instability (RMI). With the aid of vorticity-based simplified models and the vortex-surface field, we find that the effect of the SBV peaks at a critical time when the vortex reconnection widely occurs in the mixing zone. Before the critical time, spikes and bubbles evolve almost independently, and we demonstrate that the variation of the kinetic energy spectrum induced by the SBV has the $-1$ scaling law at intermediate wavenumbers using the model of vortex rings. This SBV effect causes the slope of the total energy spectrum at intermediate wavenumbers to evolve towards $-3/2$ at the critical time. Subsequently, the SBV effect diminishes and the energy spectrum decays to the $-5/3$ law. Inspired by the vortex dynamics, we develop a model for estimating the mixing width and validate the model using numerical simulations of the multi-mode RMI with various modes of initial perturbations. This model captures the nonlinear growth of the mixing width before the self-similar growth stage.
Resonance in dialogue: the interplay between intersubjective motivations and cognitive facilitation
Authors: PÕLDVERE NELE , JOHANSSON VICTORIA , PARADIS CARITA
Published: August 2021

abstract

Dialogic resonance, when speakers reproduce constructions from prior turns, is a compelling type of coordination in everyday conversation. This study takes its starting point in resonance in stance-taking sequences with the aim to account for the interplay between intersubjective motivations and cognitive facilitation in resonance production. It analyzes stance-taking sequences in the London–Lund Corpus 2, determining (i) the type of stance alignment (agreement or disagreement), and (ii) the time lapse between the stance-taking turns. The main findings are, firstly, that resonance is more likely than non-resonance to be used by speakers who express disagreement than agreement, which we interpret as a mitigating function of resonance, and, secondly, that the turn transitions are faster in resonating sequences due to cognitive activation in the prior turn. We propose that the face-saving intersubjective motivation of resonance combines with its facilitating cognitive effect to promote appeasing communication.
Flexible Nation: The Turkish Nation under the Justice and Development Party’s Rule
Authors: Kaftan Gizem
Published: August 2021

This article explains how the Turkish nation’s composition has changed under Justice and Development Party rule. Turkish nationalism and Turkish national identity have dramatically changed since 2010, when the Kurdish Opening process was started by former prime minister Recep Tayyip Erdoğan. The Syrian refugee crisis and the influx of Syrian refugees into Turkey created another change in Turkish national identity. Increasing religiosity in Turkey and the use of Islam by the Justice and Development Party created a flexible nation, where all Sunni Muslims can be considered members even though they are not ethnically Turkish. The author uses primary sources, such as President Recep Tayyip Erdoğan’s speeches since 2010, to show how his discourse became more embracing of non-Turkish Muslim groups and created a dynastic understanding of nationalism based on religion rather than the idea of an ethnically homogenous, secular Turkish nation.
The dead archive: governance and institutional memory in independent Mozambique
Authors: Machava Benedito , Gonçalves Euclides
Published: August 2021

Translated from the Portuguese expressionarquivo morto, the dead archive is a site where files that have lost their procedural validity are stored for a determined number of years before they are destroyed or are sent to permanent archives. In Mozambique, where awareness and institutional capacity for proper archival procedures are still being developed, a common feature of the dead archive is the way in which files are untidily piled up with old typewriters, furniture, spare parts and other material debris of bureaucratic work and administration. In these archives, more than forty years of institutional and public memory lie ignored in leaky, damp basements across the country and in serious danger of irreparable damage. Drawing from various stints of historical and anthropological field research conducted between 2009 and 2016 in Maputo, Niassa and Inhambane provinces, this article examines the dead archive in order to explore the relationship between institutional memory and governance during the long period of austerity in Mozambique. Based on our investigation of the multiple layers of the dead archive, we argue that the Mozambican post-socialist government has sought to control institutional memory as a way to keep the ruling party in power in the context of multiparty politics. While the public sector has experienced conditions of austerity since independence, we show how, during the socialist period (1975–90) of single-party rule, the state's relationship with institutional memory was more progressive, with transparent and communicative archival practices. In contrast, despite the combination of public sector reforms and progressive legislation regarding the right to information, the multiparty democratic period (1990 to the present) has seen an exacerbation of administrative secrecy leading to less transparent and communicative archival practices.

This is an ethnography of internet scams in Abidjan through which I attempt to develop a theory of digital sorcery. Thebrouteursof Côte d'Ivoire impersonate Europeans in social media profiles and seduce others into falling in love with them. After months of flirtatious messaging and photo exchanges, disaster strikes their avatar and they ask for an emergency wire transfer from their digital lover. While millions of euros of income are sent to Abidjan every year, thebrouteurssay they can no longer succeed without the use of occult forces, and they turn to marabouts for assistance. During my fieldwork in 2015, rumours circulated thatbrouteurwealth depended on the blood sacrifice of children for its success. As Ivoirians increasingly employ smartphones and social media in their daily life, the anxieties concerning the illusions and manipulations of the virtual world become enmeshed with those of the occult second world. I suggest that the overlap between hacker technology, con artistry and occult power outlined in Ivoirian urban rumour suggests a model for rethinking the space of virtuality in the global economy as a form of magical semiosis, one that can be every bit as vitality draining as witchcraft itself.
Risk and labour in the archives: archival futures from Uganda
Authors: Taylor Edgar C.
Published: August 2021

The history of archival management in Uganda reveals the foundational relationship between austerity and colonial archival institutions. This article discusses how impoverishment and self-interested editing were central to the bureaucratization of colonial archives at their founding. Extreme austerity in the wake of structural adjustment in the 1980s accelerated archival decay while adding new uncertainties to archivists’ work. Postcolonial archivists’ strategies of risk management and repair work have helped to preserve archives from potentially nefarious editing by partisan officials and publics. However, neglect and decay have also constrained the circulation of archives in public life and have reinforced colonial institutional violence. These conditions of postcolonial institutions require continuous hazardous labour from individuals embedded in the margins of state bureaucracy. This article emphasizes the backstage of archival labour and the risks that archivists navigate in preserving – and managing the public life of – relics of contentious pasts.
Combining CBT and sertraline does not enhance outcomes for anxious youth: a double-blind randomised controlled trial
Authors: Hudson Jennifer L. , McLellan Lauren F. , Eapen Valsamma , Rapee Ronald M. , Wuthrich Viviana , Lyneham Heidi J.
Published: August 2021

Background

Anxiety disorders are the most prevalent mental disorder in children and young people. Developing effective therapy for these children is critical to reduce mental disorders across the lifespan. The study aimed to evaluate the efficacy of combining cognitive behavioural therapy (CBT) and sertraline (SERT) in the treatment of anxiety in youth, using a double-blind randomised control trial design.

Methods

Ninety-nine youth (ages 7–15 years) with an anxiety disorder were randomly allocated to either individual (CBT) and SERT or individual CBT and pill placebo and assessed again immediately and 6 months after treatment.

Results

There were no significant differences between conditions in remission of primary anxiety disorder or all anxiety disorders. Furthermore, there were no significant differences in rates of change in diagnostic severity, parent-reported anxiety symptoms, child-reported anxiety symptoms or life interference due to anxiety.

Conclusions

The efficacy of CBT for children and adolescents with anxiety disorders is not significantly enhanced by combination with a short-term course of anti-depressants over and above the combined effects of pill placebo.
Investigating verbal and nonverbal indicators of physiological response during second language interaction
Authors: Lindberg Rachael , McDonough Kim , Trofimovich Pavel
Published: August 2021

Second language (L2) researchers have long acknowledged that affective variables (e.g., anxiety, motivation, positive emotions) are essential in understanding L2 learner psychology and behavior, both of which influence communication and have implications for language learning. However, there is little research investigating affective variables during L2 interaction, particularly from a dynamic rather than a static, trait-oriented perspective. Therefore, this study examined 60 L2 English speakers’ affective responses in real time during a paired discussion task using galvanic skin response sensors to capture speakers’ anxiety. Analyses focused on speakers’ speech, their behavioral reactions, and the content of their discussion while experiencing anxiety episodes (high vs. low arousals). Findings revealed that speakers glanced away, blinked, and used self-adaption gestures (touching face, hair-twisting) significantly more frequently during high arousals than low arousals, whereas head nods were found to occur significantly more often during low arousals. In comparison to low arousals, a larger proportion of high arousals occurred while discussing personal topics. Implications are discussed in terms of the role of affective variables in communication processes.
Interpretation preferences in contexts with three antecedents: examining the role of prominence in German pronouns
Authors: Patterson Clare , Schumacher Petra B.
Published: August 2021

This paper focuses on the relational notion of prominence, in which entities of equal type are ranked according to certain prominence-lending features. In German two demonstrative forms, “der” and “dieser”, can function like personal pronouns in English. It has been proposed that processing “der” involves computing a prominence hierarchy of the prior referents, and excluding the referent with the highest prominence rank. The demonstrative “dieser” has not been extensively tested. In the current study, personal and demonstrative pronominal forms were investigated following ditransitive contexts, where three potential antecedents are available, in two rating experiments. The personal pronoun showed flexibility in that it received equally high ratings for all three antecedents in canonical configurations. The ratings fordieserfollowed a graded sensitivity to thematic role prominence, with lowest scores when referring to prominent antecedents (agents) and the highest scores for the least prominent antecedents (patients), with scores for the medium prominence candidate (recipients) differing from both.Derfollowed a similar but not identical pattern, with a less marked difference between lower prominence candidates. Positional information also has a strong influence on demonstratives. In sum, final interpretation is sensitive to fine-grained differences in prominence hierarchies.

Literature search strategies for PubMed and Google were developed. Retrieved citations were posted on the DEA-IG Web site. Members of the DEA-IG received an email notification when new alerts were available. An informal survey of the DEA-IG members was used to provide feedback after the pilot.

Results

Six alerts were issued during the pilot (June 2019–September 2020) with a total of 170 citations. The bulk of the information were 124 PubMed indexed citations, and of these, 96 were retrieved by the PubMed search strategies. Google searches were not found to be useful, but ongoing horizon scanning work at the Canadian Agency for Drugs and Technologies in Health (CADTH) provided additional information. Based on retrospective sorting, we considered thirty-five PubMed citations to be highly relevant for health technology assessment (HTA). The response rate to the survey was limited (seventeen respondents), but most respondents found the alerts useful for their work.

Conclusions

The results of this pilot project can be used to revise search strategies and information sources, improve the relevance of the alerts, and plan for expanded dissemination strategies.

Published: August 2021

Introduced as an interdisciplinary area that combines multi-agent systems, data mining and knowledge discovery, agent mining is currently in practice. To develop agent mining applications involves a combination of different approaches (model, architecture, technique and so on) from software agent and data mining (DM) areas. This paper presents an investigation of the approaches used in the agent mining systems by deeply analyzing 121 papers resulting from a systematic literature review. An ontology was defined to capitalize the knowledge collected from this study. The ontology is organized according to seven main facets: the problem addressed, the application domain, the agent-related and the mining-related elements, the models, processes and algorithms. This ontology is aimed at providing support to decisions about agent mining application design.

Tuberculosis (TB) is the leading cause of death caused by single pathogenic microorganism, Mycobacterium tuberculosis (MTB). The study aims to explore the associations of microRNA (miRNA) single-nucleotide polymorphisms (SNPs) with pulmonary TB (PTB) risk. A population-based case−control study was conducted, and 168 newly diagnosed smear-positive PTB cases and 251 non-TB controls were recruited. SNPs located within miR-27a (rs895819), miR-423 (rs6505162), miR-196a-2 (rs11614913), miR-146a (rs2910164), miR-618 (rs2682818) were selected and MassARRAY® MALDI-TOF System was employed for genotyping. SPSS19.0 was adopted for statistical analysis, non-conditional logistic regression was performed. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were computed to estimate the associations. Associations of haplotypes with PTB risk were performed with online tool. Rs895819 CT/CC genotype was associated with reduced PTB risk among female population (OR = 0.45, 95% CI: 0.23–0.98), P = 0.045. Haplotypes (combined with rs895819, rs2682818, rs2910164, rs6505162 and rs11614913) TCCCT, TAGCC, CCCCC, CCGCT and TCGAT were associated with reduced PTB risk and the ORs were 0.67 (95% CI: 0.45–0.99), 0.49 (0.25–0.94), 0.34 (95% CI: 0.14–0.81), 0.22 (95% CI: 0.06–0.84) and 0.24 (95% CI: 0.07–0.79), respectively; while the haplotypes of TAGCT, CCCCT, CACCT and TCCAT were associated with increased PTB risk, and the ORs were 3.63 (95% CI: 1.54–8.55), 2.20 (95% CI: 1.00–4.86), 3.90 (95% CI: 1.47–10.36) and 2.95 (95% CI: 1.09–7.99), respectively. Rs895819 CT/CC genotype was associated with reduced female PTB risk and haplotype TCCCT, TAGCC, CCCCC, CCGCT and TCGAT were associated with reduced PTB risk, while TAGCT, CCCCT, CACCT and TCCAT were associated with increased risk.
New and old puzzles in the morphological conditioning of coronal stop deletion
Authors: MacKenzie Laurel , Tamminga Meredith
Published: August 2021

This paper probes the well-documented morphological effect on coronal stop deletion (CSD, also called /t,d/-deletion), by which there is more deletion in monomorphemes like mist than in regular past tense forms like missed. We observe that there are, in principle, additional morphological distinctions that could be made within each category: for instance, the “regular past” category contains perfect and passive participles; the “monomorpheme” category typically contains compounds and suffixed forms. We demonstrate that several of these newly introduced distinctions actually have significant effects on CSD rates in a corpus of Philadelphia English. And we argue that these new distinctions are worth attending to because they have consequences for two existing accounts of the basic morphological effect. In each case, we show that the existing accounts do not straightforwardly capture the additional significant distinctions we identify, calling the explanatory power of those accounts into question.
Identifying Appropriate Neuropsychological Tests for Uneducated/Illiterate Older Individuals

Published: August 2021

Objectives:

We investigated the utility of traditional neuropsychological tests in older uneducated/illiterate individuals without dementia to determine the possibility that they are likely not appropriate for this group.

Methods:

We assessed the neuropsychological performance of 1122 older adults [≥65 years old; mean age: 74.03 (SD = 5.46); mean education: 4.76 (SD = 2.5) years; women: n = 714], in the context of the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD), a population-based study conducted in Greece.

Results:

We based our analyses on three groups: high-functioning/cognitively healthy (i.e., without dementia) uneducated/illiterate individuals (n = 80), high-functioning/cognitively healthy educated/literate individuals (n = 932), and low-functioning/cognitively impaired educated/literate individuals (presumably with dementia; n = 110). We used binary regression analyses with Bonferroni correction to investigate whether test performance differentiated uneducated/illiterate from educated/literate individuals. Models were adjusted for age and sex; raw test scores were the predictor variables. The uneducated/illiterate cohort was at a disadvantage relative to the healthy educated/literate group on all variables but verbal memory recognition and consolidation, congruent motor responses, and phonological fluency clustering (p > .002). Moreover, only word list learning immediate and delayed free recall and delayed cued recall differentiated the high-functioning/cognitively healthy uneducated/illiterate from the low-functioning/cognitively impaired educated/literate group, favoring the former (p’s < .002).

Conclusions:

Our findings suggest that only particular verbal memory test variables are fair in determining whether older uneducated/illiterate individuals have functional/cognitive impairment suggestive of a neurodegenerative process. On all other neuropsychological variables, this cohort was at a disadvantage. Therefore, we highlight the need for identifying appropriate methods of assessment for older uneducated/illiterate individuals.
Interference suppression in bilingualism: Stimulus-Stimulus vs. Stimulus-Response conflict

Published: August 2021

Studies examining the potential effects of bilingualism on interference suppression show inconsistent results. Our study approaches this topic by distinguishing two potential subcomponents within interference suppression (i.e., Stimulus-Stimulus and Stimulus-Response conflict). We investigated the two subcomponents through their operationalisation in different tasks and examined the role of language proficiency in modulating it. A sample of 111 young adult participants performed four non-linguistic cognitive tasks measuring both visual and auditory domains of cognitive control. Bilinguals outperformed monolinguals in tasks involving Stimulus-Stimulus conflict, but showed comparable performance in tasks involving Stimulus-Response conflict. Specific effects of language proficiency on cognitive control were observed: group differences in auditory inhibition and visual orienting were only observed between high-proficient bilinguals and monolinguals. Taken together, types of conflicts involved in interference tasks and language proficiency could differentially affect performance in monolinguals and bilinguals.
