Curriculum Co-creation in a Postdigital World: Advancing Networked Learning and Engagement
Authors: Lubicz-Nawrocka Tanya , Owen John 
Published: April 2022

AbstractLiterature on curriculum co-creation tends to focus on in-person experiences of teaching and learning. However, the Covid-19 pandemic has spurred on learners and teachers to co-create curricula in new and creative ways. This article examines curriculum co-creation in a postdigital world focusing on the connections between curriculum co-creation and networked learning. Drawing on Hodgson and McConnell’s conceptualisation of six key practices of networked learning, the authors explore how these practices connect to curriculum co-creation in theory and in a specific example from a fully online module that ran effectively during the Covid-19 pandemic. The authors conclude that networked learning and curriculum co-creation foster postdigital thinking and dialogue, which advance many elements of excellent learning and teaching to benefit both students and staff as we continue to navigate the ‘new normal’.
Conductivity vs functionalization in single-walled carbon nanotube films
Authors: Jouni Mohammad , Fedorko Pavol , Celle Caroline , Djurado David , Chenevier Pascale , Faure-Vincent Jérôme 
Published: April 2022

AbstractDiazo functionalization is a chemical method that changes the conductance of metallic single-walled carbon nanotubes (SWCNTs) by disrupting the C–C double bonds. Its application to native mixtures of metallic and semiconducting SWCNTs is a promising way of large-scale production of semiconducting SWCNTs for use in electronics. This has been well studied on isolated SWCNTs, but the implications on the conductivity of SWCNT materials are still unclear. Here, we study the conductivity of such functionalized SWCNT films with a progressively decreased metallic/semiconducting ratio in a wide range of temperatures (4–300 K) to unravel the charge transport mechanisms of metallic and semiconducting SWCNT subnetworks to show how these components participate in the total conductivity of the films. At low functionalization degree (below 0.2 mol%), the conductivity is dominated by a subnetwork of metallic SWCNTs through two parallel mechanisms: a Luttinger liquid mechanism and a Variable Range Hopping process. Higher functionalization (over 0.4 mol%) destroys the Luttinger liquid mechanism, and a second parallel Variable Range Hopping process arises, attributed to the conduction through the semiconducting SWCNTs. At these high functionalization degrees, the SWCNT film behaves as a material with the desired semiconducting properties.

Learning the noise fingerprint of quantum devices
Authors: Martina Stefano , Buffoni Lorenzo , Gherardini Stefano , Caruso Filippo 
Published: April 2022

AbstractNoise sources unavoidably affect any quantum technological device. Noise’s main features are expected to strictly depend on the physical platform on which the quantum device is realized, in the form of a distinguishable fingerprint. Noise sources are also expected to evolve and change over time. Here, we first identify and then characterize experimentally the noise fingerprint of IBM cloud-available quantum computers, by resorting to machine learning techniques designed to classify noise distributions using time-ordered sequences of measured outcome probabilities.
A Sense of Place with Landmark Judgments: Anthropogenic Justice, Wildlife Extinction, and Climate Change
Authors: Rush Peter D. 
Published: April 2022

AbstractIt will be familiar to many that the environmental emergency of our times generates a number of difficulties for our thinking of law and society. It is argued in this essay that the languages of place-making make some sense of these predicaments. The essay proceeds through the close reading of an Extinction Rebellion protest and two landmark judgments. The protests, and their policing, are keyed to specific places and their atmospheres. A first judgment concerns the destruction of habitat and the extinction of native wildlife species; a second concerns the impact of coal mining on greenhouse gas emissions and climate change. A sense of place emerges with the aesthetic reason of judgment. The emblems and topics of legal speech, it is argued, give form and technique to the writing of place. A renewed jurisprudence of topography makes legible the meeting places of law and the environmental emergency.

Abstract

Background:
Minority and older adult patients remain underrepresented in cancer clinical trials (CCTs). The current study sought to examine sociodemographic inequities in CCT interest, eligibility, enrollment, decline motivation, and attrition across two psychosocial CCTs for gynecologic, gastrointestinal, and thoracic cancers.

Methods:
Patients were approached for recruitment to one of two interventions: (1) a randomized control trial (RCT) examining effects of a cognitive-behavioral intervention targeting sleep, pain, mood, cytokines, and cortisol following surgery, or (2) a yoga intervention to determine its feasibility, acceptability, and effects on mitigating distress. Prospective RCT participants were queried about interest and screened for eligibility. All eligible patients across trials were offered enrollment. Patients who declined yoga intervention enrollment provided reasons for decline. Sociodemographic predictors of enrollment decisions and attrition were explored.

Results:
No sociodemographic differences in RCT interest were observed, and older patients were more likely to be ineligible. Eligible Hispanic patients across trials were significantly more likely to enroll than non-Hispanic patients. Sociodemographic factors predicted differences in decline motivation. In one trial, individuals originating from more urban areas were more likely to prematurely discontinue participation.

Discussion:
These results corroborate evidence of no significant differences in CCT interest across minority groups, with older adults less likely to fulfill eligibility criteria. While absolute Hispanic enrollment was modest, Hispanic patients were more likely to enroll relative to non-Hispanic patients. Additional sociodemographic trends were noted in decline motivation and geographical prediction of attrition. Further investigation is necessary to better understand inequities, barriers, and best recruitment practices for representative CCTs.

Published: April 2022

Abstract

Objectives:
In mass casualty scenarios, patients with apparent hemodynamic and respiratory stability might have occult life-threatening injuries. These patients could benefit from more accurate triage methods. This study assessed the impact of point-of-care ultrasound on the accuracy of secondary triage conducted at an advanced medical post to enhance the detection of patients who, despite their apparent clinically stable condition, could benefit from earlier evacuation to definitive care or immediate life-saving treatment.

Methods:
A mass casualty simulated event consisting of a bomb blast in a remote area was conducted with 10 simulated casualties classified as YELLOW at the primary triage scene; patients were evaluated by 4 physicians at an advanced medical post. Three patients had, respectively, hemoperitoneum, pneumothorax, and hemothorax. Only 2 physicians had sonographic information.

Results:
All 4 physicians were able to suspect hemoperitoneum as a possible critical condition to be managed first, but only physicians with additional sonographic information accurately detected pneumothorax and hemothorax, thus deciding to immediately evacuate or treat.
Industrial evaluation of design heuristics for additive manufacturing
Authors: Blösch-Paidosh Alexandra , Shea Kristina 
Published: April 2022

Abstract
Additive manufacturing (AM) has gained prominence over the last 15 years and become a viable manufacturing option. Since there is great industrial interest to implement serial production of products using AM, the education of engineers in design for additive manufacturing (DfAM) is important today. DfAM extends on design for manufacturing to provide knowledge about the new design opportunities enabled by AM. A set of design heuristics for additive manufacturing (DHAM) to assist designers with conceptual-level DfAM has previously been proposed. In this paper, these DHAM are evaluated through workshops with 3 engineering companies and 19 engineers, in which the participants re-design existing company products for AM using the DHAM as an aid, and then give feedback. The DHAM are well received by the workshop participants, and they find that the DHAM are good for teaching others about the capabilities of AM, provide a checklist of items to consider to help avoid oversights, and encourage the generation of new ideas. Criticisms include the number of examples provided and the lack of information about how to implement the ideas concretely. It is also found that the DHAM fulfil 16 of 18 criteria for early design phase DfAM methods, identified in academic literature.

AbstractBackgroundEstimates of depression in suicidal behavior in South Asia would help to formulate suicide prevention strategies in the region that hasn't been assessed yet.ObjectivesWe aimed to systematically assess the prevalence of depression in fatal and non-fatal attempts of suicide in eight South Asian countries.MethodsWe searched Medline, Embase, and PsychINFO by specific search terms to identify articles assessing depression in fatal and non-fatal attempts of suicide in South Asian countries published between 2001 and 2020. Two separate meta-analyses were conducted for fatal and non-fatal attempts. Due to the high heterogeneity of studies (96–98%), random-effects models were used to calculate pooled prevalence rates.ResultsA total of 38 studies was identified from five south Asian countries (India [27], Pakistan [6], Sri Lanka [3], Nepal [1], and Bangladesh [1]). The majority of studies (n= 27) were published after 2010. Twenty-two studies reported non-fatal attempts, and sixteen reported suicide. The prevalence of depression among non-fatal attempts ranged from 14% to 78% where the pooled prevalence rate was 32.7% [95% CI 26–39.3%]. The prevalence of depression among suicides ranged from 8% to 79% where the pooled prevalence estimate was 37.3% [95% CI 26.9–47.6%].ConclusionsThis review revealed the pooled prevalence of depression among fatal and non-fatal suicidal attempts in South Asian countries, which seems to be lower when comparedto the Western countries. However, a cautious interpretation is warranted due to the heterogeneity of study methods, sample size, and measurement of depression.

AbstractObjectives:Consumer satisfaction is considered one of the most important measures of service quality in child mental health; however, there is limited understanding of factors that influence satisfaction. The objective of this study was to investigate key factors influencing satisfaction with care (SWC) in ADMiRE, a specialist service for young people (YP) with attention deficit hyperactivity disorder (ADHD).Methods:Parents/carers (n = 67) and YP > 9 years (n = 44) attending ADMiRE completed an anonymous Experience of Service Questionnaire (ESQ), a quantitative/qualitative measure of service user satisfaction. Parents/carers also completed symptom severity rating scales. Data were analysed to determine (i) overall SWC, (ii) the relationship between parent- and youth-reported SWC and (iii) the impact of symptom severity on SWC. Thematic analysis of qualitative ESQ data was completed.Results:Parents/carers were significantly more satisfied than YP (p = 0.028). Symptom severity did not impact significantly on parent/carer satisfaction. YP with severe hyperactive/impulsive and inattentive ADHD symptoms were significantly less satisfied with care than those with less severe ADHD symptoms (p = 0.022 and p = 0.017 respectively). Factors related to the therapeutic alliance were identified as being particularly important to both parents/carers and YP.Conclusions:This is the first Irish study that has investigated the impact of symptom severity on service user satisfaction in a child mental health service. The results highlight the different perspectives of YP and parents and provide novel insights into the impact of symptom severity on service user satisfaction. The importance of the therapeutic alliance should not be underestimated in future development of services.
Socially Responsible human resource management and employees' turnover intention: the effect of psychological contract violation and moral identity
Authors: Zhao Hongdan , Chen Yuanhua , Xu Yujuan , Zhou Qiongyao 
Published: April 2022

AbstractThis study explores the impact of socially responsible human resource management (SR-HRM) on the turnover intention by exploring the effects of psychological contract violation (PCV) and moral identity. Using a sample of 284 employees in China, we found that PCV mediated the negative relationship between SR-HRM and turnover intention. Moral identity moderated the direct effect of PCV on turnover intention as well as the indirect effect of SR-HRM on turnover intention via PCV, such that both the direct and indirect effects were stronger for employees with a low level of moral identity compared to those with the high level of moral identity. Findings from this study provide a greater understanding of the internal mechanisms and boundary conditions of SR-HRM that affect turnover intentions. Study findings also provide guidance to organizations seeking to reduce employee turnover.

AbstractDoes temporal thought extend asymmetrically into the past and the future? Do asymmetries depend on cultural differences in temporal focus? Some studies suggest that people in Western (arguably future-focused) cultures perceive the future as being closer, more valued, and deeper than the past (a future asymmetry), while the opposite is shown in East Asian (arguably past-focused) cultures. The proposed explanations of these findings predict a negative relationship between past and future: the more we delve into the future, the less we delve into the past. Here, we report findings that pose a significant challenge to this view. We presented several tasks previously used to measure temporal asymmetry (self-continuity, time discounting, temporal distance, and temporal depth) and two measures of temporal focus to American, Spanish, Serbian, Bosniak, Croatian, Moroccan, Turkish, and Chinese participants (totalN = 1,075). There was an overall future asymmetry in all tasks except for temporal distance, but the asymmetry only varied with cultural temporal focus in time discounting. Past and future held a positive (instead of negative) relation in the mind: the more we delve into the future, the more we delve into the past. Finally, the findings suggest that temporal thought has a complex underlying structure.
Global variations in regional degradation rates since the Last Glacial Maximum mapped through time and space
Authors: Madoff Risa D. , Putkonen Jaakko 
Published: April 2022

AbstractTopographic diffusivity is an often-used metric of regolith mobility. It accounts for the collective effects of climate, substrate, fauna, flora, and other factors on hillslope degradation and is used to model natural lowering in landscapes. The present study assesses where temporal variations in diffusivity derived from known past climate fluctuations have occurred. We also determine where significant differences might result when modeling landscape degradation if a long-term constant diffusivity is applied instead of diffusivity that varies through time. A space-for-time substitution approach was implemented. Through use of a transfer function that correlates current diffusivities with air temperatures, we mapped the relative diffusivities globally at a 500 yr temporal resolution for 21 ka. The analyses spanned all land areas from the tropics to the poles with a spatial resolution of 3.70° latitude by 3.75° longitude using paleo-temperature data from the TraCE-21ka global paleoclimate model. The results show Arctic and subarctic regions with the highest relative maximum diffusivities and largest variance from current values. The results suggest strong surficial dynamics in the Arctic and subarctic regions driven by local and spatially transient deglaciation and long-term stability in the tropics that correlates with relatively stable climate there through the past 21 ka.
Naming Others: Translation and Subject Constitution in the Central Highlands of Angola (1926–1961)
Authors: Dulley Iracema 
Published: April 2022

AbstractThis paper proposes an ethnographic theorization of the relationship between naming, translation, and subject constitution via the analysis of forms of interpellation in colonial Angola. It engages critically with systemic/structural renderings of colonial society that portray social positions as oppositional to argue for a deconstructive approach attentive to historical disjunctions between naming and social positioning. Dwelling on core signifiers in Portuguese and Umbundu, the paper describes the iterative chain of substitutions through which subjects have been constituted, that is, reduced and transformed. For instance, how are the Umbundu status signifiersocimbunduandocindelereduced in their respective translations as “black” and “white”? How can translation both re-enact and challenge the constitution of racialized and ethnicized categories of difference? How is this related to transformations in Angolan history? The argument put forth challenges the conventional understanding of social categories in the context of Portuguese colonialism in Angola by arguing that the performativity of naming and translation constitutes subjects via both fixation and displacement. Therefore, the possibility of transformation does not lie in the intentional action of subjects, but in their capacity to operate within the fractures of the relationship between language and society by drawing on disjunctions between signifier and signified, names and social positioning, subjective constitution and sociopolitical context.

Published: April 2022

AbstractIn this paper, the assembly problem of circular-rectangular compound peg and hole parts in automatic assembly is proposed for the first time, and an automatic assembly method based on six-dimensional force sensor is summarized. Firstly, according to the quasi-static equilibrium condition, the contact states are summarized. It is concluded that there are 7 categories of 44 contact states in insertion stage and the forces conditions to maintain each contact state; Secondly, according to the analysis of the force/moment relationship, the jamming diagram is drawn, and the conditions of jamming are analyzed. Thirdly, the assembly strategy is discussed, including contact state recognition strategy, hole searching strategy, and pose adjustment strategy. Finally, combined with impedance control, the assembly theory is verified in ADAMS, and the assembly with minimum clearance of 0.1 mm is achieved.
UDE-based task space tracking control of uncertain robot manipulator with input saturation and output constraint

Published: April 2022

AbstractThis paper investigates the trajectory tracking problem of uncertain robot manipulators with input saturation and output constraints. Uncertainty and disturbance estimator (UDE) is used to tackle the model uncertainties and external disturbances. Different from most existing methods, UDE only needs the bandwidth of the unknown plant model for design, which makes it easy to be implemented. Nonlinear state-dependent function is employed to cope with output constraints and a second order auxiliary system is constructed to solve the input saturation. Finally, an UDE-based tracking controller is proposed based on the backstepping method. With the proposed control scheme, the input saturation and the output constraints are not violated, and all signals in the closed-loop system are bounded. The comparative simulation results of a two-link robot manipulator are utilized to validate the effectiveness and superiority of the proposed control method.
