Improving Discourse following Traumatic Brain Injury: A Tale of Two Treatments
Authors: Henderson Amy , Roeschlein Mackenzie A. , Wright Heather Harris 
Published: May 2020

AbstractPersons with traumatic brain injury (TBI) often present with discourse-level deficits that affect functional communication. These deficits are not thought to be primarily linguistic in nature but instead are thought to arise from the interaction of linguistic and cognitive processes. Discourse processing treatment (DPT) is a discourse-based treatment protocol which targets discourse deficits frequently seen in TBI. Attention Process Training-2 (APT-2) is a published treatment protocol which targets four levels of attention. The purpose of this article is to investigate the effectiveness of DPT and APT-2 in improving discourse production and cognition in adults with TBI. Our results suggest that DPT results in greater improvement in discourse informativeness and coherence, but the combination of DPT and APT-2 resulted in greater generalization to untrained stimuli. Both DPT and APT-2 appear to have some potential to improve cognition, but there was intersubject variability with regard to which treatment is more effective.
Computational aspects of 19F NMR
Authors: Krivdin Leonid B. 
Published: May 2020

This review covers most recent advances in computation of 19F NMR chemical shifts and spin – spin coupling constants involving 19F nucleus calculated at different levels of theory. It deals mainly with electronic and stereochemical effects influencing these parameters, with a special emphasis on practical applications of such calculations. For 19F NMR chemical shifts, a good deal of attention is focused on less common solid state studies, in addition to much more popular liquid state data. For spin – spin coupling constants, the main interest is concentrated on the most popular 19F–1H, 19F–13C and 19F–19F couplings providing marked stereochemical behaviour.
The bibliography includes 149 references.

Countability in Mbyá
Authors: Thomas Guillaume 
Published: May 2020

Abstract
This paper investigates the distribution of nouns in Mbyá (Tupi-Guarani), with respect to plural marking, numerals and quantifiers. The study reveals the existence of a robust grammatical distinction between a class of count nouns, which consists mostly of individual denoting nouns, and a class of mass nouns, which consists mostly of substance denoting nouns.
On the semantic properties of mass and count nouns in Guajajára (Tenetehára)
Authors: Chamorro Pilar , Bonfim Duarte Fábio 
Published: May 2020

Abstract
In this paper we show that Guajajára has grammaticalized the distinction between mass and count nouns, but that the coding
of this distinction is different from the systems of coding in classifier languages, number-marking languages, and number-neutral languages
(Chierchia 1998a, 1998b, 2010; Wilhelm 2008). As a result, we conclude that Guajajára presents a
challenge to the tripartite classification of languages proposed in Chierchia’s work, since Guajajára number marking is non-inflectional and
optional when plural is already expressed by other quantificational expressions. Furthermore, in Guajajára notional mass nouns can pluralize
and directly combine with numerals without the mediation of container or measure constructions in contexts where conventional and
non-conventional container and units of measurement are implied. This last observation suggests that coercion is not a mechanism that
operates in this language.
“Pero… y las caritas esas, ¿cómo se ponen?”
Authors: Maíz-Arévalo Carmen 
Published: May 2020

Abstract
Using a netnographic approach, the present study aims to find out whether age plays a role in the realization of the speech act of complimenting as performed by a Facebook community of Peninsular Spanish users. To that purpose, a corpus of a hundred compliments was collected. Fifty of these compliments were performed by users in the age range of 18–25 and the other fifty by users in the age range of 60–75. To control for the gender variable, only compliments produced by female users were gathered. Results show that age plays a role in the way compliments are produced, especially with regards to the use of non-verbal elements (e.g., emoji). Verbal realization strategies also show interesting differences in relation to age.
“Tu masssss ❤ te amo”
Authors: Placencia María Elena , Powell Hebe 
Published: May 2020

Abstract
Complimenting behavior within a group of Ecuadorian teenage girls on Instagram was examined by Placencia (2019). Using the same corpus, in the present study we consider the responses to compliments offered. These responses, while short, are remarkably complex, containing both text and images (emojis) and indeed textual stand-ins for paralinguistic cues such as laughter. Responses were grouped according to Holmes’s (1986) taxonomy and the data shows a distinct preference for accepting compliments given (97.7%), with fewer sub-strategies used compared to other studies. These results are considered in the context of the type of photos examined and the overall function that Instagram appears to fulfil for the group of teenagers in this study. Beyond what might be termed the basic strategies of accepting or rejecting compliments, we also look at the rich and varied sub-strategies used by the girls in this Instagram community, which they employ to express solidarity and show modesty when accepting compliments.
#Lovely country, #wonderful people
Authors: Danziger Roni , Kampf Zohar 
Published: May 2020

Abstract
Considering the popularity of Twitter in digital diplomacy, this paper explores how international politicians enhance sociability by performing online compliments and praise. Drawing on 480 amicable actions collected from 14 accounts of foreign-affair actors, we analyze the prevalence, content, form, and functions of diplomatic expressions of positive evaluation. Our findings indicate that although having important functions on interpersonal, national, and international levels, compliments and praise are uncommon actions in digital diplomacy. We suggest that the lack of diplomatic “approbation protocol” and the perils of context collapse on Twitter encourage international actors to perform solidarity by other means. We also propose that the mediated and diplomatic contexts extend the traditional definition of compliments and blur differences in cultural speaking styles.
Healthy lifestyle, dieting, fitness and bodybuilding
Authors: Baczkowska Anna 
Published: May 2020

Abstract
This paper studies compliments that occur in selected Polish online discussion forums devoted to topics related to a healthy lifestyle, dieting, fitness and bodybuilding. The aim of the investigation is to find out which syntactic structures, topics and functions are prevalent, and whether the Corpus Query Language is an adequate tool to analyze compliments in data retrieved from Internet forums. The study has shown that (1) the most frequent structures differ from those identified in previous studies, (2) the predominant topics identified in this study only partially overlap with previous studies, and (3) the most common function is expressing solidarity and establishing rapport. The corpus-based methodology and CQL, with some limitations, proved useful and allowed effective examination of a large database of ca. six million words.
Compliments in congratulatory tweets to Spanish Olympic athletes
Authors: Hernández Toribio María Isabel , Mariottini Laura 
Published: May 2020

Abstract
In this chapter we examine the form and function of compliments in congratulatory tweets sent to Spanish athletes during the 2016 Rio Olympic Games. The study is based on a corpus of 500 tweets taken from the profiles of 14 Spanish athletes (5–21 August 2016). Compliments play an important role in congratulatory remarks as they serve to either realize congratulations or to support them. Findings show that congratulatory acts supported by compliments or stand-alone compliments acting as congratulatory acts exceed tweets of congratulatory remarks alone. The use of direct compliments is found more frequently within the corpus than indirect ones, with elliptical and vocative constructions being the most prominent. It is suggested that this may be a consequence of the tendency to conciseness of Twitter and other social networks.

Published: May 2020

This article analyses the assessments of Truth Commissions (TCs) and their association with positive socio-emotional climate and trust in institutions in six South American countries The sample consisted of 4,442 participants (53.3% women), 13 to 90-years-old ( M = 37.4, SD = 15.7). Participants answered a questionnaire comprised of scales that evaluated their knowledge, evaluation, emotions and social sharing about the TC, as well as the socio-emotional climate and the trust in institutions. Comprehensive Meta-analysis procedure and multiple linear regression were carried out. Positive evaluation of the TCs was related to trust in institutions ( r̅ = .23, random model) and a positive socio-emotional climate ( r̅ = .31, random model). Political positioning and age showed limited effects. Finally, the associations of positive TC evaluation with social climate and trust in institutions were found to be positively moderated by contextual factors.
I’ve changed my mind. The intentions to be childless, their stability and realisation
Authors: Albertini Marco , Brini Elisa 
Published: May 2020

ABSTRACT
Childlessness has been increasing over the last decades in most European societies. Previous studies have mostly focused on the ‘involuntary’ component of childlessness, and factors affecting voluntary childlessness remained poorly understood. This article presents an analysis of the factors associated with the intention to be childless, and the realisation and stability of this intention in the short-term. The theory of planned behaviour is applied to relate childlessness intentions with their realisation and to explore the role of ideational factors on the variability of possible fertility outcomes. Results show that more than 90% of the respondents realised their desire to remain childless. Childlessness intentions, however, tend to be less stable than parenthood ones, at all ages with the exception of individuals aged 40 years or more. Individuals’ attitudes towards childbearing and perceived social pressure toward parenthood strongly correlate with the stability of the intentions toward childlessness or parenthood, whereas socio-economic characteristics and factors connected with individuals’ perceived control count for little. The study sheds light on people who voluntarily live without children and suggests that being childless is not always the result of opportunities and external constraints, but it could be a choice originating from personal and intimate domains of life.

Published: May 2020

Abstract
The commissioning and operation of a particle therapy centre requires an extensive set of detectors for measuring various parameters of the treatment beam. Among the key devices are detectors for beam range quality assurance. In this work, a novel range telescope based on a plastic scintillator and read out by a large-scale CMOS sensor is presented. The detector is made of a stack of 49 plastic scintillator sheets with a thickness of 2–3 mm and an active area of 100 × 100 mm2, resulting in a total physical stack thickness of 124.2 mm. This compact design avoids optical artefacts that are common in other scintillation detectors. The range of a proton beam is reconstructed using a novel Bragg curve model that incorporates scintillator quenching effects. Measurements to characterise the performance of the detector were carried out at the Heidelberger Ionenstrahl-Therapiezentrum (HIT, Heidelberg, GER) and the Clatterbridge Cancer Centre (CCC, Bebington, UK). The maximum difference between the measured range and the reference range was found to be 0.41 mm at a proton beam range of 310 mm and was dominated by detector alignment uncertainties. With the new detector prototype, the water-equivalent thickness of PMMA degrader blocks has been reconstructed within ± 0.1 mm. An evaluation of the radiation hardness proves that the range reconstruction algorithm is robust following the deposition of 6,300 Gy peak dose into the detector. Furthermore, small variations in the beam spot size and transverse beam position are shown to have a negligible effect on the range reconstruction accuracy. The potential for range measurements of ion beams is also investigated.

Published: May 2020

Abstract
We investigate the structural, electronic and magnetic properties of LaMnO3/BaTiO3 heterostructure by means of ab initio calculations within the GGA+U approach. We consider the heterostructure when ferroelectric polarization in the BaTiO3 film is oriented perpendicular to the LaMnO3 substrate. We present atom and spin-resolved density of states calculations for LaMnO3/BaTiO3 heterostructure with different number of BaTiO3 overlayers as well as layer-resolved spectra for the conducting heterostructure. We found that the LaMnO3/BaTiO3 heterostructure becomes conducting with a significant spin polarization indicating that the interface becomes ferromagnetically ordered. The propose concept of a ferroelectrically controlled interface ferromagnetism that offers the possibility to design novel electronic devices.
Mind–Body Therapy via Videoconferencing in Patients With Neurofibromatosis: Analyses of 1-Year Follow-up
Authors: Lester Ethan G , Gates Melissa V , Vranceanu Ana-Maria 
Published: May 2020

Abstract

Background
Neurofibromatosis (NF) is a rare genetic disorder associated with substantial deficits in quality of life (QoL). We have previously shown that in this population the Relaxation Response Resiliency Program for NF (3RP-NF) delivered via live videoconferencing is associated with sustained improvement in QoL from baseline through 6-month follow-up over and above an attention placebo control..

Purpose
To examine between- and within-group changes in QoL domains from baseline to 1-year follow-up and 6-month to 1-year follow-up.

Methods
We enrolled and randomized 63 adults with NF. Of these, 52 completed the 6-month follow-up and 53 completed 1-year follow-up. We assessed QoL with the World Health Organization Quality of Life—Brief.

Results
Participation in the 3RP-NF was associated with sustained improvement from baseline to 1 year in physical health QoL (12.68; 95% confidence interval [CI]: 1.76 to 23.59; p =.024) and social relations QoL (16.81; 95% CI: 3.03 to 30.59; p =.018) but not psychological and environmental QoL, over and above the control (between group changes). Participants in the 3RP-NF improved from baseline to 1 year in psychological (8.16; 95% CI: 1.17 to 15.14; p =.023) and social relations QoL (9.93; 95% CI: 1.10 to 18.77; p = .028; within-group changes). There were no other significant differences between or within groups from baseline/6 months to 1 year.

Conclusions
The live video 3RP-NF shows promise in improving QoL dimensions over the course of 1 year. Results should be replicated in a fully powered randomized controlled trial.

Ethnic Differences in Experimental Pain Responses Following a Paired Verbal Suggestion With Saline Infusion: A Quasiexperimental Study
Authors: Letzen Janelle E , Dildine Troy C , Mun Chung Jung , Colloca Luana , Bruehl Stephen , Campbell Claudia M 
Published: May 2020

Abstract

Background
Ethnic differences in placebo and nocebo responses are an important, yet underresearched, patient factor that might contribute to treatment disparities.

Purpose
The purpose of this study was to examine ethnic differences in pain trajectories following a verbal suggestion paired with a masked, inert substance (i.e., saline).

Methods
Using a quasiexperimental design, we examined differences between 21 non-Hispanic Black (NHB) participants and 20 non-Hispanic White (NHW) participants in capsaicin-related pain rating trajectories following a nondirectional verbal suggestion + saline infusion. All participants were told that the substance would “either increase pain sensation, decrease it, or leave it unchanged.” A spline mixed model was used to quantify the interaction of ethnicity and time on ratings.

Results
There was a significant Ethnicity × Time interaction effect (β = −0.28, p = .002); NHB individuals reported significantly greater increases in pain following, but not before, the verbal suggestion + saline infusion. Sensitivity analyses showed no change in primary results based on differences in education level, general pain sensitivity, or condition order.

Conclusions
The present results showed ethnic differences in pain response trajectories following a verbal suggestion + saline infusion and suggest that future research rigorously examining possible ethnic differences in placebo/nocebo responses is warranted.
Metals and Particulates Exposure from a Mobile E-Waste Shredding Truck: A Pilot Study
Authors: Ceballos Diana , Zhou Michael , Herrick Robert 
Published: May 2020

Abstract
The US electronics recycling industry has introduced a novel mobile electronic waste (e-waste) shredding truck service to address increasing needs for secure data destruction of e-waste. These trucks can shred small electronics with data security concerns at remote locations for a wide variety of clients. Shredding jobs usually involve hand-feeding electronic waste (e-waste) for 4–10 h day−1, 1–5 days. Shredding of e-waste has been documented as a source of high metal exposures, especially lead and cadmium. However, no studies have been done to assess exposures on mobile e-waste shredding trucks. We conducted a pilot cross-sectional exposure assessment on a mobile e-waste shredding truck performing a 65-min shredding job (truck back door open and no local exhaust ventilation) in the Greater Boston area in 2019. We collected area air and surface wipe samples for metals along with real-time particulate measurements from different locations. The highest metal air concentrations (e.g. 2.9 µg-lead m−3) were found next and 1.8 m away from the shredder operator inside the semi-trailer. Metal surface contamination was highest near the shredder (e.g. 1190 µg-lead 100 cm−2) and extended to other parts of the truck. Near the shredder, the concentration of ultrafine particles was up to 250 000 particles cm−3 and particulate matter 2.5 mm or less in diameter (PM2.5) was up to 171 µg m−3, and neither returned to background levels after 40 min of inactivity. A diesel-electric generator was used to power the shredder and could have contributed to some of the particulate emissions. We found that mobile e-waste shredding trucks are a source of metals and particulates emissions. We recommend the industry adopts better controls for shredding inside trucks, such as local exhaust ventilation with proper filtration and use of personal protective equipment, to protect workers’ health and the environment.
Plasma adenosine and neurally mediated syncope: ready for clinical use

Abstract
Either central or peripheral baroreceptor reflex abnormalities and/or alterations in neurohumoral mechanisms play a pivotal role in the genesis of neurally mediated syncope. Thus, improving our knowledge of the biochemical mechanisms underlying specific forms of neurally mediated syncope (more properly termed ‘neurohumoral syncope’) might allow the development of new therapies that are effective in this specific subgroup. A low-adenosine phenotype of neurohumoral syncope has recently been identified. Patients who suffer syncope without prodromes and have a normal heart display a purinergic profile which is the opposite of that observed in vasovagal syncope patients and is characterized by very low-adenosine plasma level values, low expression of A2A receptors and the predominance of the TC variant in the single nucleotide c.1364 C&gt;T polymorphism of the A2A receptor gene. The typical mechanism of syncope is an idiopathic paroxysmal atrioventricular block or sinus bradycardia, most often followed by sinus arrest. Since patients with low plasma adenosine levels are highly susceptible to endogenous adenosine, chronic treatment of these patients with theophylline, a non-selective adenosine receptor antagonist, is expected to prevent syncopal recurrences. This hypothesis is supported by results from series of cases and from observational controlled studies.
Persistent westward drift of the geomagnetic field at the core–mantle boundary linked to recurrent high-latitude weak/reverse flux patches
Authors: Nilsson Andreas , Suttie Neil , Korte Monika , Holme Richard , Hill Mimi 
Published: May 2020

SUMMARY
Observations of changes in the geomagnetic field provide unique information about processes in the outer core where the field is generated. Recent geomagnetic field reconstructions based on palaeomagnetic data show persistent westward drift at high northern latitudes at the core–mantle boundary (CMB) over the past 4000 yr, as well as intermittent occurrence of high-latitude weak or reverse flux patches. To further investigate these features, we analysed time-longitude plots of a processed version of the geomagnetic field model pfm9k.1a, filtered to remove quasi-stationary features of the field. Our results suggest that westward drift at both high northern and southern latitudes of the CMB have been a persistent feature of the field over the past 9000 yr. In the Northern Hemisphere we detect two distinct signals with drift rates of 0.09° and 0.25° yr−1 and dominant zonal wavenumbers of m = 2 and 1, respectively. Comparisons with other geomagnetic field models support these observations but also highlight the importance of sedimentary data that provide crucial information on high-latitude geomagnetic field variations. The two distinct drift signals detected in the Northern Hemisphere can largely be decomposed into two westward propagating waveforms. We show that constructive interference between these two waveforms accurately predicts both the location and timing of previously observed high-latitude weak/reverse flux patches over the past 3–4 millennia. In addition, we also show that the 1125-yr periodicity signal inferred from the waveform interference correlates positively with variations in the dipole tilt over the same time period. The two identified drift signals may partially be explained by the westward motion of high-latitude convection rolls. However, the dispersion relation might also imply that part of the drift signal could be caused by magnetic Rossby waves riding on the mean background flow.
