Comparison of System Characteristics of the Guangzhou Water Transit System with Its International Peers
Authors: Burke Matthew I. , Dai Lizhu , Leung Abraham
Published: June 2020

With ports having moved downriver, redevelopment of central city areas and waterfronts has transformed the urban centres and created new economic bases for once industrial cities. Water transit systems, such as New York’s East River and City-Wide Ferry services and Gothenburg’s harbor ferries, are being installed by economic development agencies as a device to stimulate further land development, provide tourism opportunities, and promote a new social engagement with the river. Guangzhou’s water transit system is the third largest in Asia by passenger volume, behind only Bangkok and Sydney. This paper describes the Guangzhou system in depth, comparing its operations favourably with the world’s leading water transit systems. Comparisons are made in vessel design, route design, terminals, operations, and fares. The Guangzhou case is distinctive, with a mixture of cross-river and parallel routes, and an especially unique approach to subsidy that may be an option for North American cities considering water transit. Opportunities to further improve the system in line with international trends are identified, as well as a research agenda to further the knowledge of water transit operations and regulation generally.

Published: June 2020

Sharks are an interesting group of vertebrates, as many species swim continuously to “ram” oxygen-rich seawater over their gills (ram ventilators), whereas other species “pump” seawater over their gills by manipulating buccal cavity volume while remaining motionless (buccal pumpers). This difference in respiratory physiology raises the question: What are the implications of these differences in lifestyle for circadian rhythms? We investigated the diel activity patterns of 5 species of sharks, including 3 ram ventilating species: the school shark ( Galeorhinus galeus), the spotted estuary smooth-hound ( Mustelus lenticulatus), and the spiny dogfish ( Squalus acanthias); and 2 buccal pumping species: the Port Jackson ( Heterodontus portusjacksoni) and draughtsboard ( Cephaloscyllium isabellum) sharks. We measured the amount, duration, and distance traveled while swimming over multiple days under a 12:12 light:dark light regime for all species and used modified light regimes for species with a clear diel rhythm in activity. We identified a surprising diversity of activity rhythms. The school shark and smooth-hound swam continuously; however, whereas the school shark swam at the same speed and covered the same distance during the day and night, the smooth-hound swam slower at night and traversed a shorter distance. A similar pattern was observed in the spiny dogfish, although this shark swam less overall. Both the Port Jackson and draughtsboard sharks showed a marked nocturnal preference for swimming. This pattern was muted and disrupted during constant light and constant dark regimes, although circadian organization of this pattern was maintained under certain conditions. The consequences of these patterns for other biological processes, such as sleep, remain unclear. Nonetheless, these 5 species demonstrate remarkable diversity within the activity rhythms of sharks.
Unilateral Neuroimaging Findings in Pediatric Craniofacial Scleroderma: Parry-Romberg Syndrome and En Coup de Sabre
Authors: Seese Ronald R. , Glaser Daniel , Furtado Andre , Thakkar Kavita , Torok Kathryn S.
Published: June 2020

Objective:

Parry-Romberg syndrome (PRS) and en coup de sabre (ECDS) are subtypes of craniofacial localized scleroderma. Systematic analyses of central nervous system imaging findings and their clinical associations in children are lacking. Here, we aim to characterize neuroimaging findings and associated neurological symptoms in these conditions.

Methods:

Neuroimaging and neurological symptoms of children evaluated at our institution with a diagnosis of PRS or ECDS were retrospectively reviewed. Laterality, location, stability, and number of lesion(s) were evaluated, as was the presence of susceptibility lesion(s) and contrast enhancement. History of seizures or headaches was noted.

Results:

From 2003 to 2019, 80 patients with PRS or ECDS were followed at our institution. Neuroimaging was completed in 73 and found to be abnormal in 25. In 12 (48%) of these 25 cases, headaches and/or seizures were present. In the vast majority of these cases (22/25, 88%), lesions were ipsilateral to skin findings. White matter was involved in 19 (76%) patients. MRI abnormalities preceded a rheumatological diagnosis in 7 (28%). Susceptibility lesions were noted in 11 (44%), and 8 (73%) of these patients endorsed a history of headaches. Most lesions were in the supratentorial compartment, did not enhance, and were stable at 1-year follow up imaging. Of those with progression, susceptibility findings were present at baseline.

Conclusions:

Neuroimaging findings in pediatric PRS and ECDS are often supratentorial, stable, unilateral, and ipsilateral to skin findings, and they can precede cutaneous findings.
Personal Risk and Protective Factors Involved in Aggressive Behavior
Authors: Gómez-Leal Raquel , Megías-Robles Alberto , Gutiérrez-Cobo María José , Cabello Rosario , Fernández-Berrocal Pablo
Published: June 2020

The study of aggression plays a prominent role in psychology and public health, because of the important adverse consequences of such behavior for victims, aggressors, and society in general. The General Aggression Model (GAM) provides a general conceptual framework for understanding the aggressive as a result of three stages: (a) inputs: personal and situational factors; (b) present internal states: affect, cognition, and arousal; and (c) outcomes: decision processes with a (non)aggressive result. The main objective of this research was to study the personal protective and risk factors most strongly associated with aggressive behavior acting at the first stage of the GAM model. A total of 282 young adult participants took part in this study. Participants were assessed for aggression levels and a set of the most relevant variables that have been associated with aggressive behavior in the previous literature. Stepwise multiple regression analysis revealed that levels of aggression were mainly associated (73.2% of the explained variance) with the following protective factors: the ability to manage emotions as a component of emotional intelligence (EI), and perspective-taking and personal distress as components of empathy, and with the following risk factors: negative and positive urgency as a component of impulsivity, fantasy as a component of empathy, negative affect, and expressive suppression of emotions. These findings provide a better understanding of the mechanisms underlying aggressive behavior and provide greater empirical value to the current theoretical models. In addition, this research can help to inform the design of more successful programs for the prevention, control, and treatment of aggressive behavior. Limitations and future lines of research are discussed.
The effect of cold environment on the buckling behavior of hybrid composites prepared by using carbon/aramid/glass
Authors: Öndürücü Ayşe , Kayıran Hüseyin Fırat
Published: June 2020

In this study, the effect of cold environment on the buckling behavior of hybrid composites kept at −18°C for certain periods was investigated. For the buckling tests, hybrid composite plates with different fiber combinations were produced using three different fibers—carbon twill, E-glass twill, and aramid twill—and an epoxy resin (Araldite/Aradur) as the matrix material. Specimens for the buckling experiments were cut from the 12-layer hybrid composite plates and the hybrid composite specimens were then divided into three different groups. The specimens in Groups I and II were kept in a refrigerator for 90 days and 150 days, respectively, while Group III specimens were kept under room conditions as the control group. The hybrid composite specimens were subjected to buckling tests as soon as their waiting times were over. The buckling behaviors of hybrid composites with different stacking sequences were examined on the basis of the data obtained from the buckling experiments. The load–displacement curves obtained from the experiments were used to calculate the critical buckling loads ( Pcrs) for each hybrid configuration. The Pcr was found to be highest for the hybrid configuration CAG (carbon/aramid/glass) with the stacking sequence [(0/−90)3]s and lowest for the hybrid configuration CAG45 with the stacking sequence [(45/−45)3]s. The hybrid composite specimens kept in a cold environment were found to have higher Pcrs than those kept under room conditions. The difference was greater in the case of the hybrid specimens kept in the cold environment for 150 days.
Concerning the queer refugee: Staceyann Chin’s transient performance
Authors: Metzger Sean
Published: June 2020

Poet, performance artist, and activist, Staceyann Chin has created with her daughter Zuri an on-line “Living Room Protest” series. This work provides a focus to discuss the queer refugee and facilitates a broader inquiry into the spatial and temporal dimensions of transient performance as expressed through a digital platform. The Chins’ collaboration destabilizes assumed oppositions between child and adult, public and private, citizen and refugee. Their performances further investigate notions of home and subjectivity by highlighting some of the contradictions that obtain in relation to discourses of forced migration and related claims for asylum. Although the short videos of the protest series recall certain elements from Staceyann Chin’s larger oeuvre (specifically her spoken word performances, her solo theater shows, and her published writings), this dialogic form presented on YouTube participates in and potentially reshapes one particular family’s role in a public sphere constructed through new media.
Development and evaluation of a composite supercapacitor-based 12 V transient start–stop power system for vehicles: Modelling, design and fabrication scaling up
Authors: Lei Chunhong , Fields Richard , Wilson Peter , Lekakou Constantina , Amini Negar , Tennison Stephen , Perry John , Gosso Michele , Martorana Brunetto
Published: June 2020

The study involves a bottom-up approach, from bottom cells to large supercapacitor pouch cells, encompassing the design, modelling and fabrication stages of the cells leading to a 12 V transient start–stop (TSS) power system for automotive applications. More specifically, the design of a large composite supercapacitor is presented, consisting of a high power density component and a high energy density component, hybridised at material level. The composition of the composite supercapacitor is optimised to be application-specific so that it satisfies a specified energy-to-maximum power ratio for the 12 V TSS system. The testing of the large composite supercapacitor pouch cells and the 12 V TSS system proves the validity of the bottom-up approach, validates the design and the proposed electric circuit model and its parameters, fitted according to experimental data of small laboratory cells and applied successfully to the large cells, and proves the high quality of the scaled-up fabrication processes. The 12 V TSS power system of seven large composite supercapacitor cells satisfies the set criteria of energy and maximum power for the specified duration, 15 Wh and 4.2 kW respectively, at a total mass of 3.94 kg, below the original set limit of 5 kg.
Verbal Working Memory, Long-Term Knowledge, and Statistical Learning
Authors: Saito Satoru , Nakayama Masataka , Tanida Yuki
Published: June 2020

Evidence supporting the idea that serial-order verbal working memory is underpinned by long-term knowledge has accumulated over more than half a century. Recent studies using natural-language statistics, artificial statistical-learning techniques, and the Hebb repetition paradigm have revealed multiple types of long-term knowledge underlying serial-order verbal working memory performance. These include (a) element-to-element association knowledge, which slowly accumulates through extensive exposure to an exemplar; (b) position–element knowledge, which is acquired through several encounters with an exemplar; and (c) whole-sequence knowledge, which is captured by the Hebb repetition paradigm and acquired rapidly with a few repetitions. Arguably, the first two are a basis for fluent and efficient language usage, and the third is a basis for vocabulary learning. Thus, statistical-learning mechanisms (and possibly episodic-learning mechanisms) may form the foundation of language acquisition and language processing, which characterize linguistic long-term knowledge for verbal working memory.
Functional connectivity of the retrosplenial cortex in rats with ischemic stroke is improved by electroacupuncture
Authors: Zhang Qingqing , Li Jianhong , Huang Sheng , Yang Minguang , Liang Shengxiang , Liu Weilin , Chen Lidian , Tao Jing
Published: June 2020

Background

The aim of this study was to investigate the central mechanism underlying the putative beneficial effects of electroacupuncture (EA) on learning and memory ability of rats with ischemic stroke-induced cognitive deficits by resting-state functional magnetic resonance imaging (fMRI).

Methods

A rat model of middle cerebral artery occlusion (MCAO)-induced cognitive deficit (MICD) was established. Rats were randomly assigned into a sham-operated control group (SC group, n = 12), untreated MICD model group (MICD group, n = 12), and MICD group receiving EA treatment at GV20 and GV24 (MICD + EA group, n = 12).

Results

Compared to the MICD group, rats in the MICD + EA group receiving EA at GV20 and GV24 exhibited significantly shortened escape latency times and crossed the position of the platform a significantly increased number of times during the Morris water maze test on the 14th day after EA, which suggested EA could significantly improve spatial learning and memory ability. Furthermore, compared to the MICD group, functional connectivity of the left retrosplenial cortex (RSC) with the left hippocampus, left RSC, right RSC, left cingulate gyrus, right cingulate gyrus, right tegmentum of midbrain, and right visual cortex was increased in the MICD + EA group; the MICD group showed decreased functional connectivity of the left RSC with the left hippocampus, right hippocampus, left RSC, right RSC, right amygdaloid body, left visual cortex, and right visual cortex.

Conclusion

These findings suggest that EA at GV20 and GV24 might improve the learning and memory ability of MICD rats by increasing the functional connectivity between the RSC and hippocampus, cingulate gyrus and midbrain, which is encouraging for the potential treatment for cognitive impairment secondary to ischemia stroke.
Model establishment of surface roughness and experimental investigation on magnetorheological finishing for polishing the internal surface of titanium alloy tubes
Authors: Peng Zhen , Song Wan-Li , Ye Cui-Li , Shi Pei , Choi Seung-Bok
Published: June 2020

A novel magnetorheological polishing process is devised to polish the internal surface of titanium alloy tubes. Under the magnetic field in polishing area between the internal surface of tube and polishing head, magnetorheological polishing fluid gets stiffened and acts as the polishing tool. In this process, rotation motion of tube and reciprocating linear motion of polishing head are carried out simultaneously resulting in helical motion trajectory of abrasive particles on workpiece surface. The finishing forces during magnetorheological polishing process including normal indentation force and shear force are analyzed and modeled. Based on the proposed model, final surface roughness Ra model is proposed to predict the polishing performance. Experiments are carried out to investigate the effect of polishing time and initial surface roughness Ra on polishing performance. The experimental results are compared with the model results, which are highly consistent. The results show a gradual growth of surface precision with polishing time and an augment of polishing efficiency with increasing initial surface roughness Ra.
Impacts of Exclusion From Municipal Water Service on Water Availability: A Case Study
Authors: Lockhart Sydney , Wood Erica , MacDonald Gibson Jacqueline
Published: June 2020

Bordering the wealthy town of Apex, North Carolina, is a majority African-American neighborhood, Irongate Drive, without town water service, relying on private wells. Residents have long sought access to town water as their wells are running dry, but problems have not been systematically documented. Using a comprehensive survey and qualitative interviews, this study assesses the frequency of water shortages, uncovers the effects on daily lives, and reports on water source preferences. Surveys showed 80 percent of households experience water scarcity. Respondents reported not having enough water to flush toilets, shower, wash hands, or do laundry. Annual well maintenance costs averaged $1405; additional costs included dealing with water shortage and buying additional items to cope. More than 75 percent actively seek municipal water, and none oppose it. These results could inform assessments of impacts of water access disparities in similar peri-urban minority communities nationwide that remain excluded from nearby municipal services.
Teacher Beliefs About Educational Reforms: A Metaphor Analysis
Authors: Baş Gökhan
Published: June 2020

This study was conducted to examine which metaphors teachers attribute to educational reforms. This research adopted a phenomenological design, in which the data were collected through metaphors. The findings indicated that teachers have negative beliefs about educational reforms. Also, the findings showed that teachers have traditional beliefs about educational reforms, rather than contemporary ones. Although teachers believed that educational reforms are a need for the education system, they perceived reform acts negatively, approaching them from a more traditional perspective.
Evaluation of surface energy for formation of multiple edge cracks using Medg-integral
Authors: Chang JH , Guo LW
Published: June 2020

A novel contour integral approach termed Medg is introduced for computation of the surface energy required for the formation of multiple edge cracks. The method is developed by reinterpretation of the conventional M-integral with deliberate delimitation of integration contour and selection of coordinate origin. Due to path independence, this method is efficient, easy to implement by using finite elements, and does not require a complicated mesh around the crack tips for good accuracy. Attention is also addressed to discussion of the size effects on proper interpretation of its physical meaning. The adequacy of the numerical results computed for the finite size corrections has been validated by using some of the available empirical formulations. It is observed that the size effect can be neglected when the crack size remains under one-tenth of the structure size. The results of a specific multi-cracked geotechnical structure suggest that, the damage state such as degradation of the structural stiffness due to the presence of edge cracks can be properly inspected by using Medg.

Published: June 2020

Despite the existence of telemedicine since the late 1950s and early 1960s, it took a pandemic to bring this technology mainstream. The critical urgency of the pandemic drove an auspicious alignment of policy, economics, and technology to facilitate the widespread implementation of telehealth. It is imperative that this synchronicity be maintained in the post-COVID era in order to optimize our health care system to be ready for the next threat to the health of the United States.
Relational Engagements With Post-Qualitative Inquiry: There Are No Blank Pages
Authors: Lester Jessica Nina
Published: June 2020

In this article, I call for engaging in the post-qualitative “turn” with a sense of relationality to the past; that is, a commitment to turning traditions with care. In doing so, I point to the situated and constructed nature of methodology, theory, and even the post-qualitative “turn.” I also offer several questions (or cautions) for the field of qualitative research to consider in moving toward what St. Pierre has called the “next next.” I conclude by highlighting the importance of defining post-qualitative inquiry in relational rather than oppositional ways.
Why Post Qualitative Inquiry?
Authors: St. Pierre Elizabeth Adams
Published: June 2020

This article explains that post qualitative inquiry is not a pre-existing humanist social science research methodology with research designs, processes, methods, and practices. It cannot be accommodated by nor is it another version of qualitative research methodology. It refuses method and methodology altogether and begins with poststructuralism, its ontology of immanence, and its description of major philosophical concepts including the nature of being and human being, language, representation, knowledge, truth, rationality, and so on. Its goal is not to find and represent something that exists in the empirical world of human lived experience but to re-orient thought to experiment and create new forms of thought and life.
Long peripheral catheters for intravenous access in adults and children: A systematic review of the literature
Authors: Qin Kirby R , Ensor Nicholas , Barnes Richard , Englin Anna , Nataraja Ramesh M , Pacilli Maurizio
Published: June 2020

Background:

Long peripheral catheters are peripheral intravenous catheters of 6–15 cm in length. They are commonly inserted into the forearm, antecubital fossa or upper arm using a direct Seldinger technique. They have proven to be valuable for peripheral intravenous catheters, particularly in patients with difficult intravenous access.

Methods:

We conducted a systematic review of studies reporting the use of long peripheral catheters. The following keywords were used: ‘long’, ‘Seldinger’, ‘guidewire’, ‘peripheral’, ‘venous’, ‘intravenous’, ‘IV’, ‘vascular’, ‘cannula’ and ‘catheter’.

Results:

Three hundred forty-one publications were identified; 16 were included in the systematic review. There were 11 adult studies and 5 paediatric studies documenting 1288 long peripheral catheters in 1271 patients. Majority of studies (12/16) were conducted in acute care settings, (emergency department, n = 6; intensive care unit, n = 3; high dependency unit, n = 1; surgical unit, n = 2). The most frequently studied long peripheral catheter was 8 cm in length and 20 G in size. Nine studies recruited patients with difficult intravenous access; 11 studies used ultrasound guidance. Insertion success rate and mean procedural time ranged between 86% and 100% and 8 and 16.8 minutes, respectively. Average catheter duration ranged between 4 and 14.7 days (mean) and 1.1 and 9 days (median). Catheter failure occurred in 4.3–52.5% of long peripheral catheters, with leakage, infiltration and dislodgement being the most frequent causes of failure. In 3 randomised controlled trials, long peripheral catheters outperformed peripheral intravenous catheters in terms of duration and failure rate.

Conclusion:

Long peripheral catheters are safe and reliable in both adults and children. In addition, long peripheral catheters may provide improved quality of care over peripheral intravenous catheters for multi-day intravenous therapy.
Cross-Sectional Study of Clients’ Satisfaction With Outpatient and Inpatient Services of Public Health Facilities of a North Indian State
Authors: Kaur Manmeet , Bashar Abu , Singh Tarundeep , Kumar Rajesh
Published: June 2020

Satisfaction with health care services is a desired outcome of health care delivery. Nonetheless, there is scant information on client satisfaction with services provided in public health facilities in India. A cross-sectional study of persons attending public health facilities in Punjab, North India, was carried out in 2016. All district hospitals, subdistrict hospitals, 2 community health centres (CHCs), and 6 primary health centres (PHCs) were randomly selected from each of the 22 districts. A 60-item pre-tested and validated questionnaire was used to collect data. Participants (3278 outpatient department [OPD] and 1614 inpatient department [IPD]) visiting health care facilities were interviewed. Majority of OPD participants were satisfied with registration process, care providers, and personal issues like safety and security at the health facilities. Major domains of dissatisfaction were long waiting time and concern shown for patients during lab tests and x-rays. Most IPD participants were satisfied with care received from nurses and doctors, availability of medicines, and hospital environment. Domains of dissatisfaction were cleanliness of rooms and bathrooms and quietness at night. Varying levels of satisfaction were observed for experiences during stay, information about new medicine being given, pain control, and locomotion to bathroom or using bedpan. Around 71% were likely to recommend the health facility to others. Satisfaction with public health facilities is context dependent. Lack of drugs and supplies, poor information about medicines, long waiting time, poor cleanliness, lack of privacy, and peace were the major reasons for dissatisfaction in our study.
Topical Imiquimod as a Treatment Option for Nodular Basal Cell Carcinoma: A Systematic Review
Authors: Huang Christina M. , Kirchhof Mark G.
Published: June 2020

Background

Surgical excision is considered standard treatment for nodular basal cell carcinoma (nBCC). However, patients who reject or are unsuited for surgery may benefit from imiquimod (IMQ) 5% cream as an alternative treatment.

Objectives

The objective of this study was to conduct a systematic review on the efficacy and safety of IMQ for the treatment of nBCC.

Materials and Methods

The terms basal cell carcinoma AND imiquimod OR Aldara were searched on Ovid-MEDLINE, EMBASE, and Cochrane Library databases. Articles were included if they reported the efficacy or side effects of IMQ for nBCC. Primary outcomes included clearance (clinical and histological), recurrence rates, and adverse events. Number of lesions/subjects, treatment regimens, length of treatment, and time to recurrence were secondary outcomes.

Results

Thirty-nine publications, totaling 738 lesions, revealed a 77.4% (335/433 lesions) clinical and 72.9% (390/535 lesions) histological clearance rate. Regimens ranged from once daily 2 days a week to twice daily 7 days a week. Average treatment duration was 8.81 (±3.49) weeks. There was a 1.80% recurrence rate after an average follow-up period of 13.03 (±15.09) months. Common adverse effects included erythema (77.2%), crusting (50.5%), pruritus (34.1%), tenderness/irritation (27.3%), ulceration (25.4%), burning (22.1%), and erosion (21.7%). Unforeseen side effects included conjunctivitis, keratitis, depigmentation, comedone formation, and ruptured epidermoid cysts.

Conclusion

Imiquimod showed clinical and histological clearance rates of over 70% for nBCC, with a recurrence rate of 1.80%. Although clearance rates are lower than surgery, IMQ can be considered as a treatment option for nBCC in those who decline or are unfit for surgical intervention.
Performance analysis of rough surface hybrid thrust bearing with elliptical dimples
Authors: Kumar Vivek , Sharma Satish C
Published: June 2020

Surface roughness is inherent to all machining processes. Therefore, even a high precision machining process renders micro-roughness to some extent on the surface of conventional materials. The asperities height of many rough engineering surfaces follows Gaussian distribution. The surface roughness on the bearing surface may significantly affect the bearing performance. Surface texturing is emerging as a new technique to improve the tribological behavior of the mating surfaces. Usually dimensions/height of micro-roughness is of order of the depth of surface textures in fluid film bearings. Neglecting micro-roughness while numerically simulating a textured surface bearing may generate inaccurate bearing performance data. In presented work, finite element simulation of textured surface hybrid thrust bearings has been performed. Surface texture is provided over thrust pad in the form of regular arrays of elliptical dimples. A parametric optimization is carried out to determine optimum attributes of elliptical dimple (axis, depth, texture length and orientation) so that the load-carrying capacity and fluid film stiffness should be maximized and film frictional power losses should be minimized. Use of textured surface (with optimum elliptical dimple attributes) results into a significant enhancement in load-carrying capacity (91.3%), film stiffness coefficient (+98.8%) and reduction in frictional power losses (−48.3%). It is also observed that elliptical dimple and micro-roughness (transverse orientation) generate synergistic effects in further enhancing the load-carrying capacity (+101.4%) and film stiffness coefficient (+112%) of the bearing.
The development of a brief measure of health personality
Authors: Martin Peter , Kim Joseph , Jasper Angelica , Baek Yousun , Russell Daniel
Published: June 2020

The purpose of this research was to develop a brief assessment of health personality, defined as a set of individual dispositions that are directly related to health. In Study 1, an initial pool of items was developed with 615 older adults, 65 years of age and older. The scale was reduced to a 15-item version for use in applied health care settings. Results indicated that the ‘Health Personality Assessment scale’ has good internal consistency, and the five-factors correlated significantly with self-reported measures of physical health and well-being. In Study 2, the scale was cross-validated with 254 older adults from the Health Literacy and Cognitive Function among Older Adults Study. The scale was refined and a third study consisted of 3,907 older adults. Reliability and validity of the scale were confirmed. Future research should evaluate the usefulness of this scale in applied healthcare settings.
Don’t drink and drive, it’s a prime: Cognitive effects of priming alcohol-congruent and incongruent goals among heavy versus light drinkers
Authors: Petzel Zachary W , Noel Jeffrey G
Published: June 2020

The present experiment assessed implicit alcohol motivations and explicit alcohol expectancies following the interaction between alcohol-congruent (i.e. social drinking) versus incongruent (i.e. driving safety) goal primes and recent drinking habits among college students ( n = 176). Heavy drinkers exhibited greater implicit alcohol approach and explicit tension reduction expectancies following social goal primes, while displaying greater implicit alcohol avoidance and explicit cognitive and behavioural impairment expectancies after driving safety goal primes. These findings indicate recent drinking habits interact with goal salience to influence explicit and implicit responses to alcohol, which has implications for the development of interventions to reduce college drinking.
Dementia as Zeitgeist: Social Problem Construction and the Role of a Contemporary Distraction
Authors: Parker Jonathan , Cutler Clare , Heaslip Vanessa
Published: June 2020

The global impact of dementia on social, political, economic, and health systems is of contemporary concern. As the world’s population ages, differentially, across countries in the Global North and Global South, dementia research and care have become embedded in primary mandates for action within the agendas of governments and health research and service organisations. Using notions of social problem construction and sociologies of legitimacy, this article seeks to explore dementia as Zeitgeist that has captured imaginations but as such is contingent and therefore precarious building an edifice that may be limited and may occlude dangers for people living with dementia. This article argues for an applied sociological approach that recognises precarity and seeks to embed a sustainable praxis-focused axiology at macro, meso, and micro levels in respect of approaches to dementia.
Task repetition, synchronous written corrective feedback and the learning of Korean grammar: A classroom-based study
Authors: Kim YouJin , Choi Bumyong , Yun Hyunae , Kim Binna , Choi Sujeong
Published: June 2020

Recently, there has been a shift in the perception of tasks. Tasks are no longer viewed as ‘one-off’ activities, and the importance of studying the role of task repetition has been increasingly addressed (Bygate, 2018). However, the way task repetition effects are mediated by other instructional conditions such as corrective feedback has not been widely researched. The current study examined the effects of task repetition and indirect synchronous written corrective feedback (WCF) during collaborative writing on the quality of students’ written task performance and the learning of Korean grammar. Fifty-four Korean as a foreign language learners completed a pretest, two collaborative writing tasks, and two posttests over 10 weeks. Their task performance was analysed in terms of complexity, accuracy and fluency, and the pretest and posttest results were scored for both suppliance and accuracy of the production of target grammatical features. The findings showed that task repetition improved writing fluency, and while synchronous WCF negatively impacted fluency during collaborative writing, it facilitated accuracy in students’ writing. In terms of the learning of target grammatical features, no significant benefit of synchronous WCF was found.
How collectivistic values affect online word-of-mouth
Authors: Pezzuti Todd , Leonhardt James M
Published: June 2020

This research uncovers a social factor that helps to explain how a consumer’s cultural orientation affects the extent to which they engage in online word-of-mouth (eWOM). The first study aggregates archival data from 52 countries and finds a positive relationship between collectivism and the extent that consumers share product-related information on social networking sites; however, collectivism is not found to relate to the extent that consumers rate and review products online. A second study examines why collectivism is positively associated with sharing product-related information on social networking sites. Collectivism is measured at the individual level among consumers in two culturally distinct countries—India and the United States. The results demonstrate that a collectivistic orientation is positively associated with similarity among members of one’s online social network (i.e., homophily) and that homophily is positively associated with sharing product-related information on social networking sites. In an increasingly global online marketplace, these findings provide needed guidance on how culture affects eWOM.
Tuning energy harvesting devices with different layout angles to robust the mechanical-to-electrical energy conversion performance

Published: June 2020

This research presents an engineering approach to fabricate multilayered electrospun nanofiber mats with high conversion performance of mechanical to electrical energy as well as improved physical stability. Electrospun polyvinylidene fluoride nanofiber webs were prepared with predefined nanofiber alignments. Fiber alignments and layer-by-layer deposition angles are considered as a tool to adjust the piezoelectric responses of multi-layered fibrous mats. Samples with optimized drum speed and maximum aligned nanofibers were utilized to fabricate multi-layered mats in different layering angles from the fiber direction of base layer (0°, 30°, 60°, 90°, 120°, 150°, and 180[Formula: see text]). The effect of layering angle of multi-layered nanogenerators on their piezoelectric responses was investigated using an image analysis approach based on the fast Fourier transform. Multivariate analyses (ANOVA) performed to reveal the relationship between increasing drum speed and nanofibers alignment and the degree of crystallization as well as the formation of β-phase in the fiber crystalline structure. Results showed that increase in drum speeds had a relative improvement in the crystal structure and the formation of β-phase in the electrospun polyvinylidene fluoride nanofiber webs. Furthermore, electrical response of samples with well-aligned polyvinylidene fluoride nanofibers collected at 1800 r/min led to 94.49% improvement when they were exposed by a periodic mechanical impact compared to non-aligned polyvinylidene fluoride nanofiber webs. Piezoelectric response of multilayered samples with layering angles of 120[Formula: see text] showed 41% improvement in their electrical output compared to those with 0[Formula: see text]. These results teach us to establish engineering design rules for textile-based energy conversion devices with different piezoelectric coefficients.

Published: June 2020

Some patients with diabetic foot ulcers (DFUs) may suffer from depression, but the latest information regarding the incidence of depression in patients with DFUs is limited. This review aimed to provide up-to-date information concerning the incidence of depression in patients with DFUs. We searched the literature in PubMed and Web of Science databases, limited to English publications. 11 eligible studies with a total of 2117 participants were included in this review. A random-effects model was applied due to high heterogeneity. The incidence of depression in patients with DFUs ranged from 26% (95% confidence interval [CI] = 19% to 33%) to 85% (95% CI = 78% to 92%), and was 47% (95% CI = 36% to 58%) after systematically summarizing. Subgroup analyses suggested that the incidence of depression were 49% (95%CI = 35% to 63%) in Europe, 37% (95% CI = 23% to 51%) in Asia, 62% (95% CI = 48% to 76%) in North America. Additionally, the incidence of depression were 40% (95% CI = 29% to 50%) in prospective studies, 55% (95% CI = 28% to 82%) in retrospective studies, 40% (95% CI = 29% to 50%) in cross-sectional studies. Furthermore, the incidence of depression were 43% (95% CI = 25% to 60%), 49% (95% CI = 35% to 63%), 68% (95% CI = 35% to 102%), 32% (95% CI = 26% to 38%), and 28% (95% CI = 18% to 38%) in patients with DFUs assessed by the Hospital Anxiety and Depression Scale, EuroQol 5-Dimension Questionnaire, Geriatric Depression Scale, Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and the Center for Epidemiologic Studies Depression Scale, respectively. The estimates were robust in the sensitivity analysis. According to the meta-regression analyses, diabetes mellitus duration ( t = 0.93, P = .422), publication years ( t = −0.72, P = .488), and age of subjects ( t = 0.01, P = .989) were not the sources of high heterogeneity. Our meta-analysis showed nearly half of patients with DFUs had depression problems.
How do partner reactions affect task set selection: Specific imitation or abstract tasks?
Authors: Müller Romy
Published: June 2020

Task set selection is facilitated when people expect a partner to perform the same task, suggesting that the features of the partner’s performance are represented. However, it is unclear how similar the partner’s reactions must be to promote compatibility effects: does a partner have to imitate subjects’ specific actions or is it enough to perform the same task while responding to different stimuli with different actions? This present study investigated this question in a joint picture–word interference paradigm. Subjects either named pictures or read words, and a partner responded by performing the same or the competing task. In Experiment 1, the partner used the same picture–word combinations as the subject and thus compatible trials implied a complete imitation. Compatibility benefits were observed. In Experiment 2, the partner performed the same or the competing task on different stimuli, producing different actions. Compatibility effects were absent. To test whether this indicates that an overlap in abstract task features is insufficient or resulted from excessive task difficulty, Experiment 3 replicated Experiment 2 with a smaller stimulus set. Compatibility benefits were found. Taken together, the results suggest that a partner’s abstract task can be represented and affect task set selection processes even without an overlap in stimulus-response mappings.

Given current urbanization trends, understanding the factors that affect local biodiversity is paramount for designing sound management practices. Existing evidence suggests that the assembly of urban communities is influenced by the environmental filtering of organisms based on their traits. Here, we investigate how environmental characteristics including isolation measurements affect the functional composition of avian assemblages in green spaces of Merida, Mexico, a Neotropical city. We sampled 22 sites, analyzed point-count data collected during fall migration, and characterized the habitat with regard to floristic and structural vegetation attributes, vegetation cover within green spaces, urban infrastructure, and isolation. We assessed the relationship between habitat descriptors and bird functional traits using RLQ and fourth-corner tests and compared trait–environment associations between resident and wintering species. Our results showed that functional composition of resident bird assemblages was linked to the environmental characteristics of the site, while the functional composition of wintering species was not. In particular, the degree of isolation revealed to be an important determinant of trait composition. Plant species richness, particularly native tree and shrub species, were critical for the functional composition of resident birds in green spaces. Our findings suggested shifts in body mass from less to more isolated green spaces. Specifically, we observed that large-bodied species predominated in isolated green spaces. This information is useful given the predicted increases in habitat isolation and transformation of green spaces due to urbanization.
Does flipped learning affect language skills and learning styles differently?
Authors: Tadayonifar Mojtaba , Entezari Mahnaz

In recent years, educators have started to use innovative pedagogies in response to the changing trends of language learning towards developing great proficiency, as the conventional approaches could no longer improve proficiency due to the interactive nature of language skills. Therefore, it is believed that the Flipped Learning (FL) approach, as one of these new pedagogies, can be appropriately used to enhance language skills due to its hybrid nature. On the other hand, the existing literature on the efficacy of the FL approach has mostly ignored psychological factors like motivation, personality traits, and learning styles. Thus, the current study aimed to see which learning styles fitted better in the FL approach. Further, it intended to explore which language skill and in which learning style the amount of improvement could be significant. Forty Iranian EFL learners took the PET pre-test and were divided into their preferred learning styles. Then, they underwent the FL approach for a semester. The results of the paired samples T-Test indicated a significant positive improvement in the students’ performance in the post-test (t (39) = −7.698, p = .000). The results of the One-way ANOVA showed that there were significant differences among learning style groups in favor of the visual style, (F (4, 35) = 2.299, p = .034), and Mixed ANOVA results indicated that the most significant difference among skills was found between speaking and writing skills, (F (3, 105) = 8.018, p = .000).

Objectives:

To report the prospective multicentre clinical evaluation of a first-in-man disposable device, Cambridge Prostate Biopsy Device, to undertake local anaesthetic outpatient transperineal prostate biopsies.

Material and methods:

Disposable single-use Cambridge Prostate Biopsy devices were manufactured based on a previous prototype. The lead site developed a user training course and disseminated the method to other sites. The Cambridge Prostate Biopsy Device (CamPROBE) was offered as an alternative to transrectal ultrasound guided biopsy to men due for a biopsy as part of their clinical management. Data on safety (infections and device performance), clinical utility, patient reported experience, biopsy quality and cancer detection were collected. Procedure time and local anaesthetic use was recorded in the lead site. The study was funded by a United Kingdom National Institute for Health Research (NIHR) i4i product development award.

Results:

A total of 40 patients were recruited (median age 69 y) across six sites; five sites were new to the procedure. Overall, 19/40 were first prostate biopsies and 21/40 repeat procedures. Both image-targeted and systematic biopsy cores taken. There were no infections, device deficiencies or safety issues reported. The procedure was well tolerated with excellent patient-reported perception and low pain scores (median of 3, scale 0–10). Histopathology quality was good and the overall cancer diagnosis rate (first diagnostic procedures) was 68% (13/19) and for significant cancers (⩾ histological Grade Group 2), 47% (9/19). In the lead centre (most experienced), median procedure time was 25 minutes, and median local anaesthetic use 11 ml ( n=17).

Conclusions:

Data from this device evaluation study demonstrate that the United Kingdom-developed Cambridge Prostate Biopsy Device/method for transperineal biopsies is safe, transferable and maintains high diagnostic yields. The procedure is well tolerated by patients, suited to the local anaesthetic outpatient setting and could directly replace transrectal ultrasound guided biopsy.

The emotional labour of doctoral criminological researchers
Authors: Waters Jaime , Westaby Chalen , Fowler Andrew , Phillips Jake
Published: June 2020

Embarking upon empirical qualitative research can be a daunting and emotional task, particularly for those who are new to research and for those who research vulnerable groups and emotive topics. Doctoral criminological researchers transect these realms, often making their research experiences acutely emotional and challenging. In addition, researchers must be able to perform emotional labour as an important part of their professional practice. Based on 30 semi-structured interviews, this is the first study to explicitly explore the emotional labour of criminological researchers. Using the lens of emotional labour, the performance and impact of undertaking qualitative data collection in doctoral research is examined. From the interview data, three main themes are discussed: emotional labour, the consequences of performing that emotional labour and coping mechanisms to deal with those consequences. The article concludes with recommendations around support and training for PhD candidates, their supervisors and the higher education sector more broadly.
