The importance of cultural psychological perspectives in pain research: Towards the palliation of Cartesian anxiety
Authors: Mazur Lucas B. , Richter Louisa , Manz Paulina , Bartels Helena
Published: December 2021

Despite widespread awareness of the psychological dimensions of pain, researchers often and easily slip into essentializing understandings that treat pain as a purely physiological experience that can be isolated within experimental research. This drive towards scientific objectivity, while at times of tremendous utility, can also limit our understanding of pain to reductionistic conceptualizations that in effect deny the subjective and even the psychological dimensions of pain. In other words, researchers often attempt to understand pain by means of empirical, scientific explanations, while being simultaneously aware that such an approach cannot grasp the phenomenon in its entirety. This yearning for deeper, ontological understanding in a world that admits of only empirical, scientific explanations has been called Cartesian anxiety. In the current study, it is argued that cultural psychology can help to alleviate this Cartesian anxiety by helping us to appreciate the psychological aspects of pain as dynamic processes of meaning making.
A class of two-sample nonparametric statistics for binary and time-to-event outcomes
Authors: Bofill Roig Marta , Gómez Melis Guadalupe
Published: December 2021

We propose a class of two-sample statistics for testing the equality of proportions and the equality of survival functions. We build our proposal on a weighted combination of a score test for the difference in proportions and a weighted Kaplan–Meier statistic-based test for the difference of survival functions. The proposed statistics are fully non-parametric and do not rely on the proportional hazards assumption for the survival outcome. We present the asymptotic distribution of these statistics, propose a variance estimator, and show their asymptotic properties under fixed and local alternatives. We discuss different choices of weights including those that control the relative relevance of each outcome and emphasize the type of difference to be detected in the survival outcome. We evaluate the performance of these statistics with small sample sizes through a simulation study and illustrate their use with a randomized phase III cancer vaccine trial. We have implemented the proposed statistics in the R package SurvBin, available on GitHub ( https://github.com/MartaBofillRoig/SurvBin ).
The inadequate approach of Directive (EU) 2019/771 towards the circular economy
Authors: García Goldar Mónica
Published: December 2021

The current social context (overconsumption, planned obsolescence, etc.) will be presented in this paper to illustrate the need for the European Consumer Law to be more aligned with sustainability objectives. To this end, the relatively recent Directive (EU) 2019/771 on certain aspects concerning contracts for the sale of goods will be analysed to conclude that it does not reflect any of the guidelines contained in the two Action Plans for the circular economy (2015 and 2020). Despite the fact that this Directive (EU) 2019/771 aims at full harmonization, a certain margin of manoeuvre is (fortunately) granted in favour of the Member States. Finally, a reference to the possibility of the market moving towards circularity (as there is now a greater demand for sustainable products) will also be made.
Quality of Life of Adopted Chinese Versus Nonadopted Dutch Children with Cleft Lip and/or Palate: A Propensity Score Matched Analysis
Authors: van Veen Martinus M. , van den Berge Bente A. , Mouës-Vink Chantal M.
Published: December 2021

Objective

To examine quality of life in internationally adopted children with cleft lip and/or palate (CL/P) versus non-adopted children with CL/P.

Design

Cross sectional study.

Setting

Multidisciplinary cleft team of a secondary and tertiary hospital in the Netherlands.

Methods

Parents of children under the age of 8 treated by the multidisciplinary cleft team of our institutions were asked to fill out a questionnaire containing demographic and clinical data and a validated parent proxy measure of cleft-specific quality of life instrument for children aged 0–8: the CleftChild-8. Adopted children were matched to non-adopted children using propensity score matching based on sex, age, type of cleft, if palatal surgery was completed and the level of education of the parent. CleftChild-8 scores were then compared between the matched samples of adopted and non-adopted children with CL/P.

Main Outcome Measure(s)

Differences in (sub)domain scores of the CleftChild-8.

Results

Most median CleftChild-8 scores of the adopted children (n = 29) were slightly lower compared to the 29 matched non-adopted children. A significant difference was seen for the domain score ‘satisfaction with (operative) treatment’ and 3 of the 13 subdomain scores: ‘post-operative results’, ‘acceptance by siblings’ and ‘acceptance by family/friends’.

Conclusions

By parent report, adopted children with CL/P experienced some areas of lower quality of life when compared to non-adopted children. Members of cleft teams should be aware of the problems associated with adoption and offer additional guidance and counseling to adopted children and their parents.

Authors: Yoshinobu Seki , Honda Goichi , Kawano Noriaki , Uchiyama Toshimasa , Kawasugi Kazuo , Madoiwa Seiji , Takezako Naoki , Takayuki Ikezoe , Wada Hideo
Published: December 2021

The aims of this study were to analyze the clinical features of a large number of cases with disseminated intravascular coagulation (DIC) associated with acute leukemia and to assess the safety and efficacy of thrombomodulin alfa (TM-α) using the French-American-British (FAB) classification of hematological malignancies. We retrospectively examined 644 patients with acute leukemia in postmarketing surveillance for TM-α. M3, M2, M4, M1, and M5 subtypes of acute myeloid leukemia (AML) and L2 and L1 subtypes of acute lymphoblastic leukemia (ALL) have been found more frequently among patients with DIC. Bleeding symptoms at baseline were more frequent in M3 and M7 subtypes. Fibrinogen concentrations were lower, and plasmin-plasmin inhibitor complex values were higher in M3 and Philadelphia-positive (Ph+) ALL. Overall DIC resolution rate was 60.2%, higher in L1 and Ph+ ALL, lower in M1, and generally higher in ALL than in AML. Overall survival rate was generally high, at 79.8%, with higher rates in L3, Ph+ ALL, and M3. Regardless of FAB subgroup, TM-α showed improved bleeding symptoms and DIC scores in clinical practice for DIC patients with acute leukemia.
Progressive Urbanism in Small Towns: The Contingencies of Governing From the Left
Authors: Beveridge Ross , Naumann Matthias
Published: December 2021

The progressive potential of urban politics is the subject of growing interest. However, debates have been largely focused on large cities with strong progressive constituencies of activists and Left-voting residents. We know little about the opportunities and challenges for progressive politics in smaller urban areas. This article addresses these shortcomings through a discussion of “progressive urbanism” in relation to small towns. In doing so, it makes three main contributions. First, it provides a definition of progressive urbanism as political projects of social justice, citizenship and democracy exploring the contingent potential of “localism,” “urban movements” and “municipal government.” Second, the article provides empirical insights on small towns in the German state of Brandenburg governed by mayors of the Left Party. Third, the article outlines challenges and opportunities of progressive urbanism in small towns, providing points of reflection for future research.

Objective: To assess the relationship between ADHD and performance of household chores. Method: A 72-question online questionnaire was developed to collect demographic/clinical information as well as parents’ assessment of their child’s performance of self-care (SC) and family-care (FC) chores. Results: The sample consists of 797 primary caregivers of children with ADHD. The overwhelming majority of parents believed that ADHD to some extent affected their child’s ability to independently and satisfactorily complete SC and FC chores. An inverse relationship was noted between parent ratings of a child’s ability to do chores independently and satisfactorily and the likelihood they believed ADHD affected chore performance. There was no difference in chore performance between children with or without co-morbid oppositional defiant disorder. Conclusion: Given that household routines, including chores, play an important role in children’s development and psychosocial adjustment, clinicians must be sensitive to the adverse impact that ADHD may have in this regard.
What makes a good minister of a political party? Impact of party- and field-related experience on party pledge fulfilment
Authors: Vodová Petra
Published: December 2021

The article examines the effect of the personal characteristics of ministers on their party and coalition partners' pledge fulfilment. Partisanship and additional party-related experience is expected to help party pledge fulfilment. Previous field-related experience should additionally open up the space for alternative principals. However, partisan motivation should be the leading mechanism for the behaviour of the minister – and field-related experience can help partisan ministers to follow party mandates better. The joint dataset of objectively testable pledges in the Czech Republic (2007–2015) supplemented by information on government ministers is used to test hypotheses. The article shows that not only holding the portfolio but also the particular features of ministers, especially those related to party-related experience, influence their ability to fulfil party promised policy.

Authors: Wilkinson Simon R.
Published: December 2021

The scientific basis for practice in child psychiatry has developed apace. And has thrown up several quandries for an accepted paradigm for good practice anchored to the diagnostic schema developed in adult psychiatry. This paper hopes to stimulate discussion about where alternative paradigms might lead us on a path to precision medicine as applied to child psychiatry.
Implementation and evaluation of clinical supervision for support workers in a paediatric palliative care setting
Authors: Beavis Jonathan , McKenzie Sian , Davis Lucy , Ellison Nell
Published: December 2021

Support workers represent a large proportion of the NHS workforce and yet their supervisory needs are often overlooked. This study focused specifically on a cohort of support workers in a community paediatric palliative care setting. Peer supervision was implemented for this group, initially face to face and then virtually. The experiences of clinical supervision for this group were investigated through responses to an online survey ( n = 25) and two focus groups ( n = 7). Survey data were analysed concurrently with a thematic analysis. The following themes and sub-themes were developed from transcribed focus groups: (1) Barriers to engagement (2) Being Listened to (3) What Worked Well: Logistics. Overall, delivery of supervision was effective to a mixed degree – though support workers appreciated a space to be listened to, their distrust of colleagues and other barriers impeded the capacity of supervision to achieve more than support and catharsis for this group. Future projects should focus on introducing more preliminary interventions to promote reflection and peer support for these groups as well as continue to consider the supervisory needs of support workers.
Hunter-gatherer or the other ethnographer? The artist in the age of historical reproduction
Authors: Taylor Nora A.
Published: December 2021

This essay revisits Hal Foster's essay in Marcus and Myers’ The Traffic in Culture (1995), “The Artist as Ethnographer,” through the lens of the Danish-Vietnamese artist Danh Vo's practice of collecting historical material. While Foster problematizes Western artists’ “primitivist fantasies” in the 1990s world of “postcolonial and “multinational capitalism,” I will consider Vo’ 21st century method of acquiring objects through auction sales, negotiations with their owners, and excavating them from their sites of origin, as reversing the roles of “self” and “other.” In purchasing White House memorabilia dated to the Vietnam-American war at auctions and salvaging antique statues from Vietnamese Catholic churches as artistic practice, Danh Vo illustrates what Hal Foster considered the problem of “othering” the self instead of “selving” the other. This essay will consider how Vo could present a case of alterity that returns the gaze and projects Vietnamese history back to the Western viewer. In her review of Vietnamese-Danish artist Danh Vo's Guggenheim retrospective in February 2018, Roberta Smith hesitated to call the artist an artist Instead, she dubbed him, somewhat pejoratively, a “hunter gatherer” and called his collection of historical objects to be illustrative of the “usual fate of non-Western countries: the debilitating progression of missionaries, colonization, military occupation and economic exploitation.” The tone of her review is precisely the kind of attitude on the part of the contemporary art world that an artist such as Danh Vo, and others who have been marginalized from institutions such as the Guggenheim, have been fighting against Yet, Vo's very presence in a solo exhibition at the Guggenheim serves to disprove Smith's own “assumption of outsideness” (Foster 1995: 304).
Small-scale multilingualism through the prism of lexical borrowing
Authors: Chechuro Ilia , Daniel Michael , Verhees Samira
Published: December 2021

Aims and Objectives:

We assess whether data on lexical borrowing obtained through field elicitation may point not only to a specific donor language but also to its specific regional variety, and whether these data are a reliable tool for reconstructing unknown historical patterns of interaction between ethnic subgroups.

Methodology:

We use quantitative analysis of the data obtained by loanword probing—elicitations of short wordlists from speakers of minority languages—to calculate the amount and identify the source of lexical transfer. We compare the results across several areas with varying degrees of bilingualism and different contact varieties of the donor language to see how this influences our results.

Data:

The data for this study come from a large-scale field study in Daghestan, with 72 people from 19 villages speaking four languages.

Findings:

Our method suggests that speech communities clearly indicate one of the regional varieties of Azerbaijani as the donor, depending on the area of data collection. We also observe that the degree of lexical convergence with the donor depends not only on the level of bilingualism observed in the specific village but also on the native language of this village, suggesting language borders as a natural constraint to the spread of lexical borrowing.

Originality:

The study is novel in that it is fully based on analysis of data on lexical convergence obtained through fieldwork on minority languages and provides quantitative results that can be compared across speech communities in the survey.

Implications:

We conclude that the method is sensitive enough to trace donorship to specific regional varieties of the donor language.

Limitations:

Our observations on the relative weight of the level of bilingualism and language affiliation of a speech community as predictors of the degree of lexical convergence require more data obtained both from other linguistic environments and by different methods.
Telemedicine and patient satisfaction during the COVID-19 pandemic: A case–control study of outpatient pediatric urology patients
Authors: Holzman Sarah A , Davis-Dao Carol A , Khoury Antoine E , Fortier Michelle A , N Kain Zeev
Published: December 2021

Telemedicine has increased during the coronavirus disease 2019 pandemic. Our objective was to determine if patient satisfaction with telemedicine differed from in-person visits in an academic pediatric urology clinic. Following outpatient telemedicine and in-person pediatric urology visits, the validated NRC Health© Patient Survey was used to assess patient experience. Patient satisfaction was assessed on a 10-point scale with scores of 9–10 considered “satisfied” and 1–8 considered “not satisfied.” Satisfaction scores between telemedicine and in-person groups were compared using McNemar’s test, Wilcoxon signed rank test, and conditional logistic regression. Fifty-one patients had urology telemedicine visits during April–August 2020 and completed the NRC Health© Patient Survey. Propensity score matching was used to identify 102 in-person controls between January 2019 and March 2020. Ninety-two percent of telemedicine patients were satisfied compared to 87% of in-person patients (OR 1.7 95% CI [0.53–5.6]). Regression analysis adjusting for matching variables demonstrated that patient satisfaction was higher for telemedicine compared to in-person visits but was not statistically significant (OR 1.5 95% CI [0.43–5.6]). Patient satisfaction with telemedicine was similar to in-person visits in the pediatric urology clinic. Reduced waiting time and convenience associated with telemedicine visits provide an opportunity for telemedicine as a useful modality for pediatric urology.

Authors: Singh Rupinder , Kumar Sanjeev , Singh Amrinder Pal , Wei Yang
Published: December 2021

In the past two decades number of studies have been reported on the use of thermoplastics as a substrate for 3D printed patch antennas. However, no work has been reported on the thermoplastic-thermosetting composite-based substrate for 3D printed patch antennas and their mechanical, morphological, rheological, and radiofrequency (RF) characterization for sensing applications. In this study low-density polyethylene (LDPE) and LDPE-5% bakelite (BAK) composite-based patch antenna (resonating frequency 2.45 GHz) were printed (for secondary recycling) on fused deposition modeling (FDM) setup. The RF characteristics were measured using a vector network analyzer (VNA). Ring resonator test was used for measuring the dielectric properties of substrates (which suggests that the dielectric constant ([Formula: see text]) and loss tangent ([Formula: see text]) for LDPE was 2.282 and 0.0045, whereas for LDPE-5%BAK the calculated [Formula: see text] and [Formula: see text] was 2.0663, 0.0051 respectively). This study highlights that for the LDPE-5%BAK composite there was a marginal increase in the size of the patch antenna; but this resulted in improved transmittance, gain, and return loss for typical sensor applications. As regards to printability of substrate, 5% BAK resulted in a melt flow index (MFI) of 9.96 g/10 min in contrast to 12.208 g/10 min for a neat LDPE sample. The selected LDPE-5%BAK composite resulted in peak strength (PS) and break strength (BS) of 16.08 MPa and 14.47 MPa (at 180 °C screw temperature, 110 rpm, and 11 kg load) while processing with a twin-screw extruder (TSE), which was observed better than the neat LDPE (PS 11.98 MPa, BS 10.79 MPa). The results were supported with porosity (%), surface roughness (Ra) analysis based upon scanning electron microscopy (SEM) and bond strength using attenuated total reflection (ATR) based Fourier transformed infrared (FTIR) analysis.
Experimental analysis and 1D simulation of an advanced hybrid boosting system for automotive applications in transient operation
Authors: Marelli Silvia , Usai Vittorio
Published: December 2021

Due to the increasingly restrictive limits of pollutant emissions, electrification of automotive engines is now mandatory. For this reason, adopting hybrid boosting systems to improve brake specific fuel consumption and time-to-boost is becoming common practice. In this paper an advanced turbocharging system is analyzed, consisting in an electrically assisted radial compressor and a traditional turbocharger. As a first step, the steady-state performance of each component was measured at the University of Genoa test rig. Subsequently another experimental campaign was carried out to evaluate the transient response of the entire turbocharging system. Two different layouts were compared: upstream and downstream. In the upstream configuration the electrically assisted compressor was placed in front of the traditional turbocharger, in the downstream configuration the e-compressor was positioned after the traditional turbocharger. The two different coupling configurations, upstream and downstream, were then modeled in 1-D simulation software following the dimensions and characteristics of the experimental line from which the exploited data originates. The models were first validated by emulating the steady-state condition and subsequently the transient response was simulated and analyzed. Secondly, the transient response of the two layouts was compared, removing the constraints imposed by the experimental activity. The practical significance of the results is outlined, with reference to the transient response of the turbocharger. The adoption of the boosting system presented here allows a fast and stable transient response. Moreover, a reduction in the engine back pressure could be achieved through an optimization of the boosting system-engine matching calculation.
Long-term care placement: The transitional support needs and preferences of spousal dementia caregivers
Authors: Brooks Deborah , Beattie Elizabeth , Fielding Elaine , Wyles Katy , Edwards Helen
Published: December 2021

Background and objectives

Many spousal caregivers experience stress, depression, loneliness, guilt and grief when placing a partner with dementia into long-term care. However, there is little research about their transitional support experiences, needs and preferences. This study aimed to gain a deeper understanding of these issues from spousal caregiver and long-term care facility staff perspectives, to inform subsequent support and intervention development.

Research design and methods

Semi-structured interviews and small group discussions were held separately with spousal caregivers ( n = 9) and care facility staff ( n = 11). Criterion and variation sampling aimed to ensure a range of experiences and perspectives. The ‘Framework’ approach was utilised for data analysis. Interpretation was with respect to underpinning models of stress-grief process in dementia caregiving.

Findings

A range of informational, psychoeducational and psychosocial supports were identified to help spousal caregivers cope better with the stressors and losses experienced throughout the transition from home to long-term care. Improved education about disease progression, information relating to long-term care provision, peer support and dementia-specific grief counselling were deemed important. Opportunities for better support within care facilities were also identified. Support should be tailored to individual needs and preferences.

Discussion and implications

The findings suggest a supportive care framework be developed, encompassing the trajectory from assessment for and admission into long-term care to end-of-life and post-bereavement support. Spousal caregivers should have their support needs assessed by trained health or social care professionals and be offered a range of support options as appropriate.
A bolt loosening detection method based on patch antenna with overlapping sub-patch
Authors: Xue Songtao , Li Xianzhi , Xie Liyu , Yi Zhuoran , Wan Guochun
Published: December 2021

Bolts are widely used in civil engineering, and the detection of bolt loosening is of great significance to ensure the safety of a structure. This paper introduces a new method for detecting bolt loosening using a customized detachable strain sensor based on a patch antenna. A patch antenna with overlapping sub-patch is proposed to measure the longitudinal elongation of the entire bolt shaft, indicating the loosening state of the bolt. When the bolt is fastened, the elongation of the bolt under tension will change the combined length of the underlying patch and the radiation sub-patch, consequently increasing or decreasing the resonant frequency of the antenna. The resonant frequency of the antenna can be measured by the vector network analyzer. Furthermore, with wireless interrogation of the strain sensor based on the patch antenna, the proposed method can also be used in the wireless detection of bolt loosening. The authors conducted a finite element analysis of the bolt and the electromagnetic simulations of the antenna. They designed the detection sensor and conducted a series of experimental tests to demonstrate how a bolt under different applied preloads can be effective and feasible under the proposed method.
Optimal sensor placement to detect ruptures in pipeline systems subject to uncertainty using an Adam-mutated genetic algorithm
Authors: Kim Chungeon , Oh Hyunseok , Chang Jung Byung , Moon Seok Jun
Published: December 2021

Pipelines in critical engineered facilities, such as petrochemical and power plants, conduct important roles of fire extinguishing, cooling, and related essential tasks. Therefore, failure of a pipeline system can cause catastrophic disaster, which may include economic loss or even human casualty. Optimal sensor placement is required to detect and assess damage so that the optimal amount of resources is deployed and damage is minimized. This paper presents a novel methodology to determine the optimal location of sensors in a pipeline network for real-time monitoring. First, a lumped model of a small-scale pipeline network is built to simulate the behavior of working fluid. By propagating the inherent variability of hydraulic parameters in the simulation model, uncertainty in the behavior of the working fluid is evaluated. Sensor measurement error is also incorporated. Second, predefined damage scenarios are implemented in the simulation model and estimated through a damage classification algorithm using acquired data from the sensor network. Third, probabilistic detectability is measured as a performance metric of the sensor network. Finally, a detectability-based optimization problem is formulated as a mixed integer non-linear programming problem. An Adam-mutated genetic algorithm (AMGA) is proposed to solve the problem. The Adam-optimizer is incorporated as a mutation operator of the genetic algorithm to increase the capacity of the algorithm to escape from the local minimum. The performance of the AMGA is compared with that of the standard genetic algorithm. A case study using a pipeline system is presented to evaluate the performance of the proposed sensor network design methodology.
Aging state detection of viscoelastic sandwich structure using redundant second generation wavelet packet transform and fuzzy support vector data description

Published: December 2021

Viscoelastic sandwich structure plays an important role in mechanical equipment, nevertheless viscoelastic material inevitably suffers from gradual aging. For guaranteeing the operation safety of mechanical equipment, it is urgent to perform the aging state detection of viscoelastic sandwich structure with vibration response signal analysis. However, the structural vibration response signal is non-stationary and its variation caused by the structural aging state change is very puny, and the abnormal state samples is lacking. The vibration-based structural aging state detection has become a challenging task. Therefore, a novel method based on redundant second generation wavelet packet transform (RSGWPT) and fuzzy support vector data description (FSVDD) is proposed for this task. For extracting sensitive aging feature information, RSGWPT is introduced to process the structural vibration response signal, and multiple energy features are extracted from the frequency-band signals to reflect structural aging state change. For accurate and automatic aging state identification, by fusing fuzzy theory, FSVDD only uses the normal state samples for training and can identify the abnormal severity degrees is developed to identify the structural aging states. The proposed method is applied on a viscoelastic sandwich structure to validate its effectiveness, and different structural aging states are created through the accelerated aging of viscoelastic material. The analysis results show the outstanding performance of the proposed method.
Educational policies requiring scripted reading curriculums limit early childhood pre-service teacher candidates
Authors: Holt Latasha
Published: December 2021

When educational policies require pre-service teacher practicum mentors to continuously implement a mandated scripted reading curriculum, limits are placed on pre-service teachers observing only these reading instruction methods. Novice teachers, who are developing their reading pedagogy, need the opportunity to explore a variety of methods identified as best reading instruction practice. When the pre-service teacher candidates are repeatedly exposed to the scripted methods in practicums, the partnership between the university professors and practicum school systems can suffer. When attempting to bridge theory and practice, the pre-service teacher candidate is affected when they observe conflicting viewpoints between college professors and the hosting practicums during a stage of professional growth and teacher development. If pre-service teachers are without practicum opportunities to try creative reading teaching methods, a result of increased negative outlooks on the profession and future teacher burn-out is a possibility.

A review investigating the influence of nanofiller addition on the mechanical, thermal and water absorption properties of cellulosic fibre reinforced polymer composite
Authors: Amjad Adnan , Anjang Ab Rahman Aslina , Awais Habib , Zainol Abidin Mohd Shukur , Khan Junaid
Published: December 2021

Composite holds great promise for future materials considering its advantages such as excellent strength, stiffness, lightweight, and cost-effectiveness. Due to rising environmental concerns, the research speed gradually changes from synthetic polymer composites to natural fibre reinforced polymer composites (NFRPCs). Natural fibres are believed a valuable and robust replacement to synthetic silicates and carbon-based fibres, along with biodegradability, recyclability, low cost, and eco-friendliness. But the incompatibility between natural fibre and polymer matrices and higher moisture absorption percentage of natural fibre limitise their applications. To overcome these flaws, surface treatment of natural fibre and nanofiller addition have become some of the most important aspects to improve the performance of NFRPCs. This review article provides the most recent development on the effect of different nanofiller addition and surface treatment on the mechanical, thermal, and wetting behaviour of NFRPCs. It concludes that the fibre surface treatment and nanofillers in natural fibre polymer composites positively affect mechanical, thermal and water absorption properties. A systematic understanding in this field covers advanced research basics to stimulate investigation for fabricating NFRPCs with excellent performance.

Authors: Panda Prasanta K , Gangwar Archana , Thite Amol G
Published: December 2021

In this study, Nylon 6 nanofiber were prepared by needle-less wire electrospinning technique. Since, the fiber diameter determines the porosity, filtration efficiency, and mechanical properties of electrospun nanofiber mat, Central Composite Design (CCD) and Response Surface Methodology have been employed to design the experiments and evaluate the interactive effects of the operating variables such as concentration of the polymeric solution, the distance between two electrodes, applied voltage, and relative humidity (RH%) on the diameter of the Nylon 6 nanofiber. With this connection, an objective of this study was to find out the most influential variables for the finest nanofiber diameter during the spinning with wire type electrode to make the highest possible effective face mask without the addition of any functional additives in it. The overall results show that the combined effect of 12% polymer concentration, 65% RH, 155 mm distance between two electrodes, and 40 kV applied positive voltage have the strongest surface response and are the most significant than the other interactive effects. The Pareto chart illustrates the order of significance affecting the Nylon 6 nanofiber diameter in the order of concentration of the polymeric solution, RH%, the distance between electrodes, and applied positive voltage. Further, bacterial filtration efficiency% of the control sample and five-layer facemask incorporated with optimized nanofiber membrane was found to be 87.4% and 97.5%, respectively, against Staphylococcus Aureus ATCC 6538 bacteria.
Identification of a Liver Progenitor Cell-Related Genes Signature Predicting Overall Survival for Hepatocellular Carcinoma
Authors: Li Xiaoyong , Lin Jiaqong , pan Yuguo , Cui Peng , Xia Jintang
Published: December 2021

Background: Liver progenitor cells (LPCs) play significant roles in the development and progression of hepatocellular carcinoma (HCC). However, no studies on the value of LPC-related genes for evaluating HCC prognosis exist. We developed a gene signature of LPC-related genes for prognostication in HCC. Methods: To identify LPC-related genes, we analyzed mRNA expression arrays from a dataset (GSE57812 & GSE 37071) containing LPCs, mature hepatocytes, and embryonic stem cell samples. HCC RNA-Seq data from The Cancer Genome Atlas (TCGA) were used to explore the differentially expressed genes (DEGs) related to prognosis through DEG analysis and univariate Cox regression analysis. Lasso and multivariate Cox regression analyses were performed to construct the LPC-related gene prognostic model in the TCGA training dataset. This model was validated in the TCGA testing set and an external dataset (International Cancer Genome Consortium [ICGC] dataset). Finally, we investigated the relationship between this prognostic model with tumor-node-metastasis stage, tumor grade, and vascular invasion of HCC. Results: Overall, 1770 genes were identified as LPC-related genes, of which 92 genes were identified as DEGs in HCC tissues compared with normal tissues. Furthermore, we randomly assigned patients from the TCGA dataset to the training and testing cohorts. Twenty-six DEGs correlated with overall survival (OS) in the univariate Cox regression analysis. Lasso and multivariate Cox regression analyses were performed in the TCGA training set, and a 3-gene signature was constructed to stratify patients into 2 risk groups: high-risk and low-risk. Patients in the high-risk group had significantly lower OS than those in the low-risk group. Receiver operating characteristic curve analysis confirmed the signature's predictive capacity. Moreover, the risk score was confirmed to be an independent predictor for patients with HCC. Conclusion: We demonstrated that the LPC-related gene signature can be used for prognostication in HCC. Thus, targeting LPCs may serve as a therapeutic alternative for HCC.

The supervisor-subordinate dyad has been well articulated in the framework of inclusive leadership and employee outcomes. Applying a multisource dataset from China, the present study develops a trickle-down model of inclusive leadership across three hierarchical levels (i.e., top managers, supervisors, and employees). Building on social learning theory and social exchange theory, the study found empirical support for the assumptions that both top management and supervisory inclusive leadership have a positive effect on employees’ innovative behavior. In addition, the findings support the proposition that supervisor's inclusive leadership mediates the effects of top manager's inclusive leadership on employees’ innovative behavior. The study also verified that vicarious learning and organizational inclusion climate jointly moderate the relationship between the top manager's inclusive leadership and the supervisor's inclusive leadership. The contribution, limitations, and future directions are also discussed.

The ethics of returning nonactionable genetic research results to individuals are unclear. Apolipoprotein L1 ( APOL1) genetic variants are nonactionable, predominantly found in people of West African ancestry, and contribute to kidney disease disparities. To inform ethical research practice, we interviewed researchers, clinicians, and African American community members ( n  =  76) about the potential risks and benefits of returning APOL1 research results. Stakeholders strongly supported returning APOL1 results. Benefits include reciprocity for participants, community education and rebuilding trust in research, and expectation of future actionability. Risks include analytic validity, misunderstanding, psychological burdens, stigma and discrimination, and questionable resource tradeoffs.

Conclusions: APOL1 results should be offered to participants. Responsibly fulfilling this offer requires careful identification of best communication practices, broader education about the topic, and ongoing community engagement.

Aiming at the problems of complex trajectory, low efficiency and high operational difficulty of the robot in multi-point punching of warp-knitted vamp, a method of optimizing punching trajectory based on improved ant colony optimization algorithm and Radau pseudospectral method is proposed. After obtaining the position coordinates of punching points, an improved ant colony optimization algorithm is used to calculate the punching sequence of the shortest path through all punching points, and then Radau pseudospectral method is used to solve the optimal trajectory of the laser punching robot. Improved ant colony optimization algorithm combines a distributed calculation method and the positive feedback mechanism. Radau pseudospectral method can transform the optimal control problems into nonlinear programming problems, and the combination of the two can quickly and reliably obtain the optimal solution. To verify the method, under the condition of selecting the same number and location of punching points, the experiments of Radau pseudospectral method to solve the trajectory planning of laser punching robot is carried out. The experimental results show that improved ant colony optimization algorithm can calculate the path of the vamp punching point in a shorter time and with high accuracy. Radau pseudospectral method can obtain smooth trajectories satisfying various constraints, which can meet the requirements of accuracy and efficiency in practical production.

Objectives

The purpose of this study was to explore social determinants of health (SDoH), and disease severity as predictors of sleep quality in persons with both Obstructive Sleep Apnea (OSA) and type 2 diabetes (T2D).

Methods

Disease severity was measured by Apnea-Hypopnea Index [(AHI) ≥ 5] and HbA1c for glycemic control. SDoH included subjective and objective financial hardship, race, sex, marital status, education, and age. Sleep quality was measured by Pittsburgh Sleep Quality Index (PSQI).

Results

The sample (N = 209) was middle-aged (57.6 ± 10.0); 66% White and 34% African American; and 54% men and 46% women. Participants carried a high burden of disease (mean AHI = 20.7 ± 18.1, mean HbA1c = 7.9% ± 1.7%). Disease severity was not significantly associated with sleep quality (all p >.05). Worse sleep quality was associated with both worse subjective (b = -1.54, p = .015) and objective (b = 2.58, p <.001) financial hardship. Characteristics significantly associated with both subjective and objective financial hardship included being African American, female, ≤ 2 years post high school, and of younger ages (all p < .01). Discussion: Financial hardship is a more important predictor of sleep quality than disease severity, age, sex, race, marital status, and educational attainment, in patients with OSA and T2D
The range of bicycle helmet performance at real world impact locations

In the United States, all bicycle helmets must comply with the standard created by the Consumer Product Safety Commission (CPSC). In this standard, bike helmets are only required to by tested above an established test line. Unregulated helmet performance below the test line could pose an increased risk of head injury to riders. This study quantified the impact locations of damaged bike helmets from real-world accidents and tested the most commonly impacted locations under CPSC bike helmet testing protocol. Ninety-five real-world impact locations were quantified. The most common impact locations were side-middle (31.6%), rear boss-rim (13.7%), front boss-rim (9.5%), front boss-middle (9.5%), and rear boss-middle (9.5%). The side-middle, rear boss-rim, and front boss (front boss-middle and front boss-rim regions combined) were used for testing. Two of the most commonly impacted regions were below the test line (front boss-rim and rear boss-rim). Twelve purchased helmet models were tested under CPSC protocol at each location for a total of 36 impacts. An ANOVA test showed that impact location had a strong influence on the variance of peak linear acceleration (PLA) ( p = 0.002). A Tukey HSD post hoc test determined that PLA at the side-middle (214.9 ± 20.8 g) and front boss (228.0 ± 39.6 g) locations were significantly higher than the PLA at the rear boss-rim (191.5 ± 24.2 g) location. The highest recorded PLA (318.8 g) was at the front boss-rim region. This was the only test that exceeded the 300 g threshold. This study presented a method for quantifying real-world impact locations of damaged bike helmets. Higher variance in helmet performance was found at the regions on or below the test line than at the region above the test line.
Cultural diversity in the Australian early childhood education workforce: What do we know, what don’t we know and why is it important?

This paper reviews current literature and research relevant to the Culturally and Linguistically Diverse (CALD) Early Childhood Education (ECE) workforce in Australia, including data from the Australian Bureau of Statistics (ABS). Australia is a highly multicultural society, with one out of every three people born overseas. Anecdotally, the Australian early childhood sector is reported to have a highly multicultural workforce. Yet there is a noticeable lack of data and research concerning cultural diversity in the Australian ECE workforce. This paper reports on the data from the ABS-Census of Population and Housing (ABS-Census), the small body of literature on the CALD ECE workforce and literature pertaining to CALD in other Australian workforces to argue that more data and research is needed. Developing a richer understanding of the status, experience and contributions of CALD educators would enable the sector to recognise and support the potential benefits of such a workforce for children and families and social cohesion in Australia.
