Intonation and Referee Design Phenomena in the Narrative Speech of Black/Biracial Men
Authors: Holliday Nicole
Published: July 2021

This study examines how men with one Black parent and one white parent variably construct their racial identities through both linguistic practice and explicit testimonials, with a specific focus on how this construction is realized in narratives about law enforcement. The data consist of interviews with five young men, aged 18-32, in Washington, D.C., and the analysis compares use of intonational phenomena associated with African American Language (AAL) in response to questions about aspects of their racial identities. Declarative intonational phrases from responses to questions were MAE-ToBi annotated and analyzed for use of intonational features subject to racialized stylistic variation, including use of L+H* versus H*, focus marking, and peak delay interval length. Results of multiple regression models indicate speakers avoid intonational features associated with AAL in police narratives, especially L+H* pitch accents with broad focus marking and longer peak delay intervals. These findings illuminate an important aspect of the relationship between linguistic performance and identity: both racial and linguistic identities are subject to topic and audience/referee-conditioned variation and individuals can use specific intonational variables to align themselves within specific audience and topic-influenced constraints. In the context of police narratives, avoidance of salient features of AAL intonation can serve as linguistic respectability politics; these speakers have motivation to employ linguistic behavior that distances them from the most societally and physically precarious implications of their identities.
Narratives of Change: Identity and Recognition Dynamics in the Process of Moving Away From a Life Dominated by Drug Use

Published: July 2021

The concepts of identity and recovery capital are recognized as being an embedded part of moving away from a life dominated by drug use. However, the link between these two concepts and the effect of broader social structures, and the normative assumptions underpinning the condition of recovery, is less explored. This article focuses on the social practices of everyday life in the foreground of identity formation, meaning that “who I am” is an inseparable part of “what I do.” A narrative approach was employed to analyze qualitative follow-up data extracted from 48 in-depth interviews with 17 males and females with drug-using experience that were conducted posttreatment on three separate occasions over a period of 2.5 years. Theories of identity formation were employed to analyze the interdependent dynamic between social structure, persona and social resources, and way of life and identity. The analyses identified four narratives related to how people present themselves through the process of changing practices. Following the work of Honneth, we argue that the positive identity formation revealed in these narratives is best understood as a struggle for recognition via the principle of achievement. However, the participants’ self-narratives reflected cultural stories—specified as formula stories—of “normality,” “addiction,” and the “addict,” which work into the concepts of self and confine options of storying experiences during the recovery process. This study demonstrate that the process of recovery is culturally embedded and constitutes a process of adaption to conventional social positions and roles. We suggest challenging dominant discourses related to “addiction as a disease” and “normality” in order to prevent stigma related to drug use and recovery. In so doing, it may contribute to broaden conditions for identity (trans)formation for people in recovery.
The Apocalypse and Political Discourse in an Age of COVID
Authors: Crossley James
Published: July 2021

It was almost inevitable that something as dominant as the COVID crisis of 2020–2021 would change how the Bible has been understood in mainstream political discourses. It is also unsurprising that the language associated with apocalypticism would come to the fore. Building on recent scholarship, this article looks at some of the language about ‘the apocalypse’ and apocalypticism, including that associated with Revelation and the New Testament, and how understandings of the Bible in contemporary political discourses have now been updated. The focus is primarily on England/Britain, America and New Zealand because these countries have been the object of much of the work on the reception history of the Bible in politics. This article also analyses the dominant cliches about the Bible as a source of liberalism, neoliberalism, left-leaning radicalism, and the far right. Examples include the use of apocalyptic themes in relation to QAnon and conspiracy theories, ready-made ironic language to describe lockdown, radical social transformation, and constructing political positions outside the traditional liberal consensus.
Families in Poverty and Noncitizenship: An Intersectional Perspective on Economic Exclusion
Authors: Lavee Einat , Dallal Edline , Strier Roni
Published: July 2021

Recent scholarship on families living in poverty has focused on immigrant and migrant families, legal and illegal. The element of citizenship has received relatively broad attention, as legal status has profound influence on the individual’s life chances. However, studies exploring relations between noncitizenship and poverty have not provided a comprehensive explanation of the mechanisms that deprive noncitizens of the possibility of accumulating sufficient material resources. The study offers a nuanced, comprehensive account of the process of economic deprivation, focusing on four main survival strategies with respect to noncitizen Palestinian families residing in Israel. Drawing on 24 qualitative in-depth interviews with adult family members, we apply the intersectionality approach to decipher mechanisms of exclusion at work in the everyday lives of illegal migrants, shaping their ability to attain material resources. Findings point to a need to adopt a transnational protection framework in order to allow economic and social inclusion of noncitizens.
Antecedents of Pregnancy Intention and Prenatal Father Engagement: A Dyadic and Typological Approach
Authors: Sayler Kristina , Hartman Sarah , Belsky Jay
Published: July 2021

Prior research indicates that unintended pregnancy is associated with poorer maternal well-being, decreased relationship stability, and compromised child health and development, whereas prenatal father engagement is linked to lower maternal stress and enhanced infant health. Here we extend such research, considering unintended pregnancy and prenatal father engagement in typological perspective to (1) identify different types of (prenatal) families; (2) explore whether problematic antecedent factors predict family type; and (3) whether family type forecasts postnatal parenting attitudes, father involvement, and marital conflict. Latent-class analysis using a subsample of participants from the Early Childhood Longitudinal Study-Birth Cohort ( n = 6100) revealed four types of families: High Pregnancy Intention/High Father Engagement (22.6%), Low Pregnancy Intention/High Father Engagement (14%), Average Pregnancy Intention/Average Father Engagement (58.2%), and Low Pregnancy Intention/Low Father Engagement (5.2%). Associational findings indicated having a highly involved father prenatally mitigates potential risks associated with an unintended pregnancy vis-à-vis family functioning.
Sources of Intergenerational Conflict in Chinese Immigrant Families in the United States
Authors: Guo Man , Lemke Amy , Dong Xinqi
Published: July 2021

Studies of family relations have not kept pace with the acceleration of international migration. To address this gap, this study relied on a survey of 545 Chinese immigrants in Chicago who reported information of 869 older parents to examine the sources of intergenerational conflict in five domains: norms/values, relationship itself, money, health, and parenting. The results of logistic regression showed that maintaining one’s traditional culture, in the form of endorsing a sense of filial obligation, was a significant protective factor against all types of conflict. Immigrants with a higher level of acculturation were more likely to report conflict regarding norms/values and relationship itself, but not more so regarding practical issues such as health, money, and parenting. Helping parents with ADLs, not IADLs, was associated with more conflict regarding monetary and health issues. Immigrants’ greater sense of mastery was associated with a lower chance of reporting norm/value-related intergenerational conflict.
Neonatal right mini thoracotomy for repair of critical pulmonary stenosis
Authors: Watanabe Naruhito , Kovalenko Oleg , Hapak Ashley , Nasirov Teimour
Published: July 2021

Over the last few decades, due to evolving surgical techniques and medical management, there has been a significant decrease in the rate of mortality and complications for neonates born with critical pulmonary valve stenosis. Median sternotomy is the standard approach; however, this longitudinal midline incision is invasive and leaves a significant scar. A right mini thoracotomy approach to this surgical repair decreases recovery time and the chance of possible future psychological distress from a visible median sternotomy scar. This is the first article to describe a right mini thoracotomy approach for critical pulmonary stenosis during the neonatal period.
Outflow graft foreign body reaction and thrombosis in HeartMate 3 left ventricular assist device
Authors: Alvarez Paulino , Humble Robert , Firchau Dennis , Briasoulis Alexandros
Published: July 2021

Outflow cannula occlusion is an infrequent complication occurring among recipients of continuous flow left ventricular assist devices. Hereby, we present a case of a 66-year-old man with a HeartMate 3 left ventricular assist device that presented 18 months after implantation and during his admission, evidence of poor left ventricular unloading and forward flow uncovered intrinsic and extrinsic outflow cannula obstruction. The patient’s course was complicated by cardiogenic shock, diffuse alveolar hemorrhage and multiorgan failure. Post-mortem examination suggested foreign body reaction as a potential contributor of outflow graft obstruction at the level of the bend relief.

Experimental systems that faithfully replicate human physiology at cellular, tissue and organ level are crucial to the development of efficacious and safe therapies with high success rates and low cost. The development of such systems is challenging and requires skills, expertise and inputs from a diverse range of experts, such as biologists, physicists, engineers, clinicians and regulatory bodies. Kirkstall Limited, a biotechnology company based in York, UK, organised the annual conference, Advances in Cell and Tissue Culture (ACTC), which brought together people having a variety of expertise and interests, to present and discuss the latest developments in the field of cell and tissue culture and in vitro modelling. The conference has also been influential in engaging animal welfare organisations in the promotion of research, collaborative projects and funding opportunities. This report describes the proceedings of the latest ACTC conference, which was held virtually on 30th September and 1st October 2020, and included sessions on in vitro models in the following areas: advanced skin and respiratory models, neurological disease, cancer research, advanced models including 3-D, fluid flow and co-cultures, diabetes and other age-related disorders, and animal-free research. The roundtable session on the second day was very interactive and drew huge interest, with intriguing discussion taking place among all participants on the theme of replacement of animal models of disease.
Epithelial lacrimal gland tumors in dogs and cats: Is the human WHO classification appropriate for animals?
Authors: Giudice Chiara , Nordio Laura , Cadonici Micol , Perelli Maria Novella , Caniatti Mario
Published: July 2021

Lacrimal gland tumors (LGTs) in dogs and cats are rare neoplasms that can affect either the nictitans (NLG) or the main lacrimal gland (MLG). A consistent classification scheme for canine and feline LGTs is lacking; however, the importance of a classification scheme for LGTs has been emphasized in the human literature, and an update to the World Health Organization (WHO) classification has recently been published. The aim of this study was to investigate the occurrence of different subtypes of canine and feline LGTs in accordance with the human WHO classification system. Epithelial LGTs ( n = 46 tumors; 38 dogs, 8 cats) were reviewed and immunophenotyping for p63, CK14, SMA, calponin, CKAE1/AE3, and CK19 was performed. Consistent with previous literature reports, lacrimal carcinomas outnumbered adenomas in dogs and cats. Based on the WHO classification of human LGTs, the most common subtypes identified in dogs were pleomorphic, ductal, adenoid cystic, and epithelial-myoepithelial carcinoma. In cats, a lower number of subtypes was observed, and adenocarcinoma “not otherwise specified” (NOS) was the most frequent diagnosis. An uncommon case of feline epithelial-myoepithelial carcinoma was also observed. The application of the human WHO-LGT classification scheme to canine and feline tumors increased the diversity of diagnoses and allowed for the identification of numerous subtypes. Further studies to identify possible correlations between pathological subtypes and prognosis are warranted.
Negotiating attachments to plastic
Authors: Sattlegger Lukas
Published: July 2021

Drawing on ethnographic research conducted in the office and warehouse of an organic wholesaler in Germany, this article presents a trans-sequential analysis of an innovation that aimed to reduce the use of plastic wrap. During the analytical reconstruction of the innovation process, the substitution of plastic wrap turned out to be a precarious process of negotiating attachments to plastic. Against this background, innovation is not simply about the implementation and substitution of technology by human actors, but about negotiating attachments that humans have towards objects within socio-technical assemblages. Drawing on actor-network theory and the sociology of attachment, the article highlights the dynamic interplay between persistence and problematization of plastic wrap, which characterizes the innovation process. This interplay is seen along several steps during the innovation process: from (1) the problematization of plastic dependency to (2) the mobilization of alternatives, to (3) resistance against measures to be implemented and (4) the enforcement of reusable strings as technological substitution and (5) to conclusive retrospection on the innovation process. The trans-sequential analysis shows that ‘getting rid of something’ might be an imperfect approach to dealing with unsustainable object relations. Instead, withdrawing is a double-sided process of detaching and attaching, removing constraints and building new ones.
New Developed Wind Pumping System
Authors: Achour Djalloul , Kesraoui Mohamed
Published: July 2021

In this paper a new wind pumping system is developed. This system is hybrid between mechanical and electrical wind pumping systems. It combines the advantages of these two systems. The developed wind pumping system consists of wind turbine, special gearbox, DC machine, battery bank, and water pump. Three wind pumping systems have been modeled and then simulated by using MATLAB/SIMULINK. The simulation results show that the developed wind pumping system has the best performance. Thus, the extracted water volume of the developed system is 984.1 m3, where mechanical and electrical systems extract 737.2 and 642.9 m3 respectively.
Rethinking the relationship between Marx’s Capital and Hegel’s Science of Logic: The tradition of creative Soviet Marxism
Authors: Dafermos Manolis
Published: July 2021

This article sheds light on the little known and poorly understood extensive discussion on the relationship between Marx’s Capital and Hegel’s Science of Logic in the tradition of creative Soviet Marxism. The exploration of the mechanism of ascending from the abstract to the concrete and its relation to the movement of thought from the concrete to the abstract was one of the key points of this discussion. The ascending from the abstract to the concrete is a crucial issue of the dialectical logic developed in German Classical Philosophy, especially in Hegel’s Science of Logic. Marx implemented the method of ascent from the abstract to the concrete to investigate a historically concrete object (the capitalist mode of production) as an organic whole.
Cooking up engagement during a pandemic: The international Great Rare Books Bake Off between the Penn State and Monash University Libraries
Authors: Riehman-Murphy Christina , Holloway Anne , Mattson Mark
Published: July 2021

In July 2020, during the COVID-19 pandemic, the Monash University Library in Melbourne, Australia, and the Penn State University Libraries in Pennsylvania, USA, leveraged their previously established international sister-library partnership to host a virtual engagement event focused on promoting the partnership and selected special collections at both institutions. The Monash–Penn State Great Rare Books Bake Off, a friendly competition collaboratively developed by the two academic libraries, engaged both institutions’ communities with their collections and resources by inviting participants to bake featured recipes from their collections and post evidence of their experiences on social media platforms. In addition to promoting awareness of the institutions’ international partnership and their respective collections, a primary goal of the collaborative project was to offer their local communities an enjoyable and creative outlet during a difficult time. This illustrative case study describes how the two institutions planned, executed, and assessed the project.
Communication channels for exchanging agricultural information among Tanzanian farmers: A meta-analysis
Authors: Mtega Wulystan Pius
Published: July 2021

This study investigates how communication channels to exchange agricultural information were chosen. Specifically, it identifies the communication channels used by farmers in Tanzania and determines the factors influencing the choice of communication channels for exchanging agricultural information. The study employs a meta-analysis review methodology in identifying, evaluating and interpreting studies relevant to the topic of interest. The results indicate that radio, mobile phones, television, fellow farmers, agricultural extension agents and newspapers were the commonly used communication channels for transferring agricultural information. Moreover, the channels’ influence, availability, affordability, communication network coverage, and the resources and facilities needed to use a particular communication channel were found to influence the choice of channels. It is concluded that understanding the audience, the characteristics surrounding messages and choosing appropriate communication channels are important for enhancing access to agricultural information. It is recommended that agricultural information providers should understand the factors surrounding communication channels before disseminating agricultural information.
Do Nutrition Education Approaches With Preschoolers and Their Caregivers Influence Retention of Biofortified Orange-Fleshed Sweet Potato on Farms? Evidence From Homa Bay County, Kenya
Authors: Ojwang Sylvester O. , Otieno David J. , Okello Julius J. , Muoki Penina , Nyikal Rose A.
Published: July 2021

Background:

Biofortified staples have been promoted widely in sub-Saharan Africa to combat micronutrient deficiencies. Contemporary projects are increasingly using elementary schools to target households with these foods.

Objective:

This study assessed the effects of integrated nutrition education approaches, targeting preschoolers and their caregivers, on retention of orange-fleshed sweet potato (OFSP) on farms in the second season after lapse of free vine dissemination initiatives.

Methods:

Rural farming households, with preschoolers and no prior engagement with OFSP, were targeted. A multistage sample of 431 preschooler–caregiver pairs was recruited for a cluster-randomized controlled trial. After issuing routine OFSP promotion activities, 15 village-level clusters of the pairs were randomized into 1 control group (3 villages) and 3 treatment arms (4 villages each) for the interventions. Baseline and follow-up household-level survey data were collected from the caregivers. The interventions included: (1) OFSP-branded exercise books, posters, and a poem to preschoolers only; (2) OFSP-oriented mobile phone mediated text messages to caregivers only; and (3) both 1 and 2 provided to individual households concurrently. Interventions 1 and 2 were single-channeled, while 3 was multichanneled. We estimated the intention-to-treat (ITT) and treatment-on-the-treated (TOT) effects using a binary logit model and a special regressor method, respectively.

Results:

Only the multi-channeled nutrition education approach had significant effects (ITT = 0.167, P = .001; TOT = .243, P = .007) on the caregivers’ likelihood to retain OFSP on their farms.

Conclusions:

The finding implies that multi-channeled agriculture nutrition education interventions through Early Childhood Development institutions can be effective in ensuring sustainable adoption of OFSP.
Life cycle assessment on automotive bumper: Scenario analysis based on End-of-Life vehicle recycling system in Japan
Authors: Jin Hao , Yu Jeongsoo , Okubo Kazuaki
Published: July 2021

In the last three decades, the increased use of plastics is rapidly becoming a global environmental issue, resulting in growing landfills, pollution of surrounding atmosphere, and possible greenhouse effect. The automotive industry, as a major demander of plastic materials, is starting to take responsibility on sustainable actions. Japan, as the world’s top tier car manufacturing and dealing country, has been taking attempts to the proper dealings of used auto-plastic. This research aims to find out current situation of auto-plastic recycling industry after these attempts. Furthermore, this research compares pros and cons of each treatment and methods under treatment environmentally as well as economically from the point of recycling operators using life cycle assessment. Bumper is chosen as the target to represent auto-plastic because of their homogeneity of composition and relatively large share of weight among all auto-plastic parts. The result shows that material recycling amount is decreasing along with recent promotion demonstration. Top reason is that material recycling even reduces carbon emissions, costs far more than energy recovery, and that subsidy is given to energy recovery but not material recycling worsens the situation. Besides that, lack of cooperation between stakeholders on the demand of secondary plastic is impeding material recycling. Also, better scheme on how to separate auto-plastic and what kind would be separated should be noticed by the policymaker.
Diagnostic Errors in Neuroradiology: A Message to Emergency Radiologists and Trainees
Authors: Hussien Abdelmohsen Radwan , Abdellatif Waleed , Siddique Zaid , Mirchia Kavya , El-Quadi Monaliza , Hussain Ali
Published: July 2021

Diagnostic errors in neuroradiology are inevitable, yet potentially avoidable. Through extensive literature search, we present an up-to-date review of the psychology of human decision making and how such complex process can lead to radiologic errors. Our focus is on neuroradiology, so we augmented our review with multiple explanatory figures to show how different errors can reflect on real-life clinical practice. We propose a new thematic categorization of perceptual and cognitive biases in this article to simplify message delivery to our target audience: emergency/general radiologists and trainees. Additionally, we highlight individual and organizational remedy strategies to decrease error rate and potential harm.

Published: July 2021

Objective:

To describe inpatient length of stay patterns, identify key drivers related to prolonged length of stay, and evaluate the relationship between length of stay and readmission in pediatric neurology

Methods:

This was a retrospective review of patients <19 years old admitted with a principal neurologic diagnosis to our hospital between January 2017 and July 2019. Scheduled admissions and hospital admissions lasting >30 days were excluded from analysis. Length of stay was obtained in addition to demographic characteristics, principal discharge diagnosis, multispecialty care, use of multiple antiseizure medications, inpatient hospital costs (ie, claims paid), and pediatric intensive care unit (ICU) admission for unplanned admissions and 7- and 30-day readmissions.

Results:

There were a total of 1579 unplanned admissions. The most common reasons for admission were seizure (n = 942), headache (n = 161), other neurologic diagnosis (n = 121), and psychiatric disorders/functional neurologic disorder (n = 60). Children admitted to the hospital for a neurologic condition have an average length of stay of 2.8±5.0 days for unplanned admissions, 4.5±7.4 days for 7-day readmissions, and 5.2±7.5 days for 30-day readmissions. Average inpatient hospital costs were $44 075±56 976 for unplanned admissions, $60 361±71 427 for 7-day readmissions, and $55 434±56 442 for 30-day readmissions. Prolonged length of stay and increased hospital costs were associated with pediatric ICU admission, multispecialty care, 7- and 30-day readmission, multiple antiseizure medications, and psychiatric disorders / functional neurologic disorders.

Conclusions:

Pediatric ICU admission, multispecialty care, readmission, multiple antiseizure medications, and psychiatric disorder / functional neurologic disorder prolong length of stay and increase hospital costs.
Chip formation and the interaction of mesoscopic geometric features of cutter
Authors: Tong Xin , Ren Yanxiang , Shen Jianing , Yu Song
Published: July 2021

Most of the researches on the properties of micro-textured tools are based on an orthogonal test, while the interaction between micro-textured parameters is ignored. Therefore, this thesis is based on an interaction test to study the cutting performance of cutting tools. According to the chip morphology obtained from the interactive test, the micro texture diameter of 60 μm is obtained when the cutting is stable. It was also found that the synergistic effect of multiple mesoscopic geometric features had a significant influence on cutting performance. By analysis, we found the optimized parameters for the milling tool were D = 60 μm, l = 100 μm, l1 = 150 μm, r = 60 μm. Furthermore, prediction models of the cutting performance were established by univariate linear regression and the validity of these models was verified. Thus, this thesis provides a reference for improving the performance of cutting tools and for achieving efficient and high-quality machining of titanium alloys.
A novel approach to radiographic detection of bucco-palatal/lingual dilacerations: A preliminary study with ImageJ
Authors: Satir Samed , Buyukcavus Muhammed Hilmi , Orhan Kaan
Published: July 2021

The purpose of our study is to determine whether bucco-palatal/lingual (BPL) root dilacerations (RD), especially in single root teeth, can be determined using the ImageJ program through only one periapical radiography. Extracted teeth without any RD ( n = 8) were determined as the control group (Group 1) and with RD in apical 1/3 part at least 20° with the longitudinal axis in the BPL direction ( n = 8) as the study group (Group 2). With the help of a simple holder system prepared, digital periapical radiographs of all teeth were taken in an anteroposterior position. Histogram analysis of all periapical radiographs was performed using the spectrum feature of ImageJ software. It was aimed to make a dilaceration analysis by comparing the groups using mean, standard deviation, minimum, maximum, and bin width values. As a result of the Mann-Whitney U test, all mean and maximum values showed a statistically significant difference between the study and control groups ( p < 0.05). This pilot study revealed that the ImageJ software can be used to diagnose BPL dilaceration in the apical 1/3 part of the root. It is important for dentists and patients that it can contribute to limiting the radiation dose to which patients will be exposed.
Active impulsive disturbance rejection and oscillation control of robot manipulator, using nonclassical rod models and proportional integral derivative controller
Authors: Babaei Alireza
Published: July 2021

Micro-electro-mechanical-systems scale robots are prone to impulsive disturbances during operation. Such disturbance leads to adverse oscillations of the robot manipulator. So, it is essential to mitigate and control such unwanted oscillations. On the other hand, to capture size dependencies of such robot elements, it is required to adopt nonclassical models. To address these cases, robot manipulator is modeled as a mechanical rod, comprehensive rod models are utilized, proportional integral derivative (PID) controller is designed, and the time-domain response of the system is simulated in MATLAB. Results show that adopting proper gain values of the PID controller leads to total rejection of the pulsive disturbances. However, findings conceal the importance of the nonclassical rod model such that strain gradient (SG) model shows less oscillatory amplitude than the classical theory (CT) model. While considering the nonlocal model effects (NL), such undesired vibrations are bigger than CT model. In other words, meanwhile, a simple PID controller can reject the disturbance for SG models; a stronger controller should be adopted to reject such pulsive disturbances with NL models. Eventually, it is valuable to note that to suppress unwanted oscillations in small-sized robots, PID closed-loop feedback controller is a decent choice because of the simplicity and less costs. Application of successful control design alongside the proper nonclassical theory leads to neutralizing the disturbances and increases the robot manipulator precision.
Welfare chauvinism across benefits and services
Authors: Eick Gianna Maria , Larsen Christian Albrekt
Published: July 2021

The article theorises how covering social risks through cash transfers and in-kind services shapes public attitudes towards including/excluding immigrants from these programmes in Western European destination countries. The argument is that public attitudes are more restrictive of granting immigrants access to benefits than to services. This hypothesis is tested across ten social protection programmes using original survey data collected in Denmark, Germany and the UK in 2019. Across the three countries, representing respectively a social democratic, conservative and liberal welfare regime context, the article finds that the public does indeed have a preference for easier access for in-kind services than for cash benefits. The article also finds these results to be stable across programmes covering the same social risks; the examples are child benefits and childcare. The results are even stable across left-wing, mainstream and radical right-wing voters; with the partial exception of radical right-wing voters in the UK. Finally, the article finds only a moderate association between individual characteristics and attitudinal variation across cash benefits and in-kind services.
Energy efficient throttling control of a multi-pressure system using a genetic algorithm and model predictive control
Authors: Huova Mikko , Linjama Matti
Published: July 2021

The energy efficiency of hydraulic cylinder drives can be increased by replacing the actuator with a multi-chamber cylinder, utilising multiple supply lines with unique pressures or a combination of the concepts. Previous studies have demonstrated significant energy savings using a cascaded control system, which requires velocity feedback to stabilise the system. To avoid the need of position or velocity sensors in harsh conditions of mobile machines, this article presents a throttling control scheme, which achieves good energy efficiency on multi-pressure systems without velocity feedback. A simulation study was performed to determine the efficiency of the system, robustness against load variations and the effect of valve response time on performance.
New perspectives of hyperspectral imaging for clinical research
Authors: Pallua Johannes D , Brunner Andrea , Zelger Bernhard , Huck Christian W , Schirmer Michael , Laimer Johannes , Putzer David , Thaler Martin , Zelger Bettina
Published: July 2021

New developments in instrumentation and data analysis have further improved the perspectives of hyperspectral imaging in clinical use. Thus, hyperspectral imaging can be considered as “Next Generation Imaging” for future clinical research. As a contactless, non-invasive method with short process times of just a few seconds, it quantifies predefined substance classes. Results of hyperspectral imaging may support the detection of carcinomas and the classification of different tissue structures as well as the assessment of tissue blood flow. Taken together, this method combines the principle of spectroscopy with imaging using conventional visual cameras. Compared to other optical imaging methods, hyperspectral imaging also analyses deeper layers of tissue.

Published: July 2021

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of 5 acyl sarcosines and 9 sarcosinate salts as used in cosmetics; all of these ingredients are reported to function in cosmetics as hair conditioning agents and most also can function as surfactants—cleansing agents. The ingredients reviewed in this assessment are composed of an amide comprising a fatty acyl residue and sarcosine and are either free acids or simple salts thereof. The Panel relied on relevant new data, including concentration of use, and considered data from the previous Panel report, such as the reaction of sarcosine with oxidizing materials possibly resulting in nitrosation and the formation of N-nitrososarcosine. The Panel concluded that these ingredients are safe as used in cosmetics when formulated to be non-irritating, but these ingredients should not be used in cosmetic products in which N-nitroso compounds may be formed.

Published: July 2021

Background:

Pulmonary hypertension (PH) is common in patients with end-stage renal disease (ESRD). Arteriovenous fistulas (AVF) creation may involve in the pathogenesis of PH. The aim of this study was to explore the impact of PH after AVF creation on the AVF failure rate in maintenance hemodialysis (MHD) patients.

Methods:

From January 1, 2009, to January 1, 2019, we retrospectively collected data of 578 MHD patients in Guangdong Provincial People’s Hospital Blood Purification Center, China. Patients were followed-up until AVF failure or death or May 25, 2020. According to the systolic pulmonary artery pressure (SPAP) within 1 year after the establishment of AVF, the MHD patients were divided into three groups: SPAP ⩽ 35 mmHg, 35 < SPAP < 45 mmHg, SPAP ⩾ 45 mmHg. The primary outcome was AVF failure defined as AVF cannot complete hemodialysis. The secondary outcomes were all-cause mortality.

Results:

A total of 578 patients were analyzed. The average age was 60.66 ± 15.34 years (58.1% men). Of these, 26.1% of patients were reported PH. The SPAP exhibited a left-skewed nonparametric distribution and the overall SPAP after the creation of AVF was 39.00 (29.00–52.00) mmHg. The median follow-up was 5.8 (5.5–6.3) years. Overall, 12.8% (74/578) patients were reported AVF failure events. There was no significant difference in AVF failure rate among three groups ( p = 0.070). A total of 111 (19.2%) died during the follow-up period. Compared with the SPAP ⩽35 mmHg group, only the all-cause death rate significantly increased in MHD patients with PH ( p < 0.001).

Conclusions:

The secondary pulmonary hypertension after AVF creation did not increase the risk of AVF failure in MHD patients, but significantly increased the risk of mortality for this portion of the patients. Future larger sample sizes, multi-center, and prospective trials are needed to make sure which type of access will benefit on their survival for MHD patients with SPAP ⩾35 mmHg.
Impact of the Coronavirus Pandemic on Substance Use Disorder Treatment: Findings from a Survey of Specialty Providers in California

Background:

As the coronavirus pandemic public health emergency begins to ebb in the United States, policymakers and providers need to evaluate how the addiction treatment system functioned during the public health emergency and draw lessons for future emergencies. One important question is whether the pandemic curtailed the use of addiction treatment and the extent to which telehealth was able to mitigate access barriers.

Methods:

To begin to answer this question, we conducted a survey of specialty addiction treatment providers in California from June 2020 through July 2020. The survey focused specifically on provider organizations that served Medicaid beneficiaries.

Results:

Of the 133 respondents, 50% reported a decrease in patients since the stay-at-home order in March 2020, with the largest decline among new patients, and 58% said more patients were relapsing. Eighty-one percent of providers said that telemedicine use had increased since the stay-at-home order. Most said that telemedicine had moderately (48%) or completely (30%) addressed access barriers.

Conclusion:

More efforts are needed to ensure that patients, and in particular new patients, receive addiction treatment during public health emergencies.

Immigrants face barriers in seeking and accessing mental health and addiction services. Health professionals are crucial in providing and promoting healthcare and it is important to understand their experiences in order to enhance the access of mental healthcare. The aim of this paper is to explore and describe health professionals’ experiences with treatment engagement among immigrants with co-occurring substance use disorders (SUD) and mental health disorders (MHD) in Norwegian mental health and addiction services. Within a collaborative approach, 3 focus group interviews were conducted with health professionals, who had provided various mental health and addiction care services to immigrants with co-occurring SUD and MHD. The focus group interviews were transcribed verbatim and analyzed using systematic text condensation. The analysis resulted in 5 main categories: (1) difficulties due to language barriers, (2) difficulties due to lack of culturally competent services, (3) difficulties due to social factors, (4) being curious and flexible improves the user-provider relationship, and (5) increasing access to mental health and addiction services. This study provides an enhanced understanding of how health professionals’ experienced treatment engagement among immigrants with co-occurring SUD and MHD in the Norwegian context. Implications of the findings for clinical practice and future research are discussed.

Advances in pediatric cancer treatment and dramatic improvement in long-term survival have made health-related quality of life (HRQOL) a priority. This study describes the HRQOL of Saudi children on cancer treatment, given the paucity of data on the subject. Parents of children undergoing cancer treatment between the ages of 2 and 12 years enrolled to answer the Arabic version of the parent proxy report PedsQL™ 3.0 cancer module. The module items were reverse-scored to a linear scale from 0 to 100, in which higher scores indicated a better HRQOL. Of the 95 study participants, 61 (64.2%) were hematological malignancies and 34 (35.8%) solid malignancies. The mean score of our sample’s total HRQOL was 72.3, which is in line with the results of similar studies worldwide. The lowest scores were observed for procedural anxiety (60.14), perceived physical appearance (67.37), and treatment anxiety (67.58), while the highest were for communication (80.21), nausea (78.32), and cognitive problems (78.32). Significant associations were reported between the patients aged younger than 5 years and procedural anxiety, those aged 5 years or older and perceived physical appearance, and frequent hospital visits and worry. Healthcare professionals should consider the poor HRQOL sub-scales and their associated risks to improve treatment outcomes.

Prosocial peer relationships, such as defending against victimization, are beneficial for integration. Using the concept of multiple categorization, this study considers the extent to which similarity in gender, being in the same classroom, and similarity in network position regarding bullying or victimization contributes to the formation of cross-ethnic defending relationships among children. Longitudinal social network models were applied to complete school-level networks of 1,325 children in eight multi-ethnic elementary schools. Although same-ethnic peers were more likely to defend each other than cross-ethnic peers, similarity in gender, being in the same classroom, and similarity in network position in bullying fostered cross-ethnic defending. Moreover, being in the same classroom increased the likelihood of cross-ethnic defending even more than it did same-ethnic defending. A better understanding of how multiple categorization contributes to positive relationships between peers of different ethnic backgrounds may help to promote interethnic integration in multi-ethnic classrooms.
On streaming-dating convergence: Music-mediated self-presentations on Tinder
Authors: Kang Edward B
Published: July 2021

This study takes a cultural anthropological approach to address the use of music taste as an instrument of self-presentation on online dating platforms by examining the partnership between Spotify and Tinder, which not only allows Tinder users to pick an anthem from Spotify’s catalog, but also displays a list of “top artists” based on data aggregated through their activity on Spotify. Using Cheney-Lippold’s formulation of the “measurable type” and Bucher’s notion of “conscious clicking” as foundational frameworks, this paper offers the term “conscious listening” to explore the ways that users play with their music taste-based identities on Tinder. In order to better theorize this phenomenon, a wide array of thinkers ranging from communications, sociology, and data/platform studies are coalesced along with the results of in-depth interviews with 10 Tinder users to analyze the recent convergence of music streaming and social dating platforms.
Evaluating the use of multimedia information when recruiting adolescents to orthodontics research: A randomised controlled trial
Authors: Knapp Peter , Mandall Nicky , Hulse Wendy , Roche Jenny , Moe-Byrne Thirimon , Martin-Kerry Jacqueline , Sheridan Rebecca , Higgins Steven ,   (for the TRECA study group)
Published: July 2021

Objective:

To compare two methods of providing information about the Bone Anchored Maxillary Protraction (BAMP) trial: standard printed information and multimedia websites, for their quality and ease of understanding, and impact on decision-making.

Design:

Randomised controlled trial.

Setting:

Orthodontic outpatient clinic in the UK.

Methods:

Participants were 109 adolescents (aged 11–14 years) attending for orthodontic treatment. While awaiting treatment they were asked to imagine being recruited to the BAMP clinical trial. They were individually randomised to receive the printed or the multimedia website information (comprising text, animations and ‘talking head’ videos). After reading or viewing the information, they completed a 9-item Likert scale Decision-Making Questionnaire (DMQ) (score range 0–36) plus three free-text questions on their evaluation of the information.

Results:

A total of 104 participants completed the questionnaire. Mean total DMQ scores were higher (more positive) in the website group (28.1 vs. 27.0), although the difference was small and not statistically significant ( P = 0.20). Analysis of individual questionnaire items showed two statistically significant differences: the website information had higher ratings on ‘easy to understand’ (Z = 3.03; P = 0.003) and ‘confidence in decision-making’ (Z = 2.00; P = 0.044). On the three free-text questions, more positive and fewer negative comments were made about the websites than the printed information.

Conclusion:

In this hypothetical trial setting, adolescent patients found that trial information conveyed on a multimedia website was easier to understand and made them more confident in their decision about trial participation. Their subjective evaluations of the website were also more positive and less negative than about the printed information. Multimedia information has the potential to increase the quality of engagement and information exchange when seeking consent for research.
