Autumn Arctic Pacific Sea Ice Dipole as a Source of Predictability for Subsequent Spring Barents Sea Ice Condition
Authors: Liang Yu-Chiao , Kwon Young-Oh , Frankignoul Claude
Published: October 2020

This study uses observational and reanalysis datasets in 1980–2016 to show a close connection between a boreal autumn sea ice dipole in the Arctic Pacific sector and sea ice anomalies in the Barents Sea (BS) during the following spring. The September–October Arctic Pacific sea ice dipole variations are highly correlated with the subsequent April–May BS sea ice variations (r = 0.71). The strong connection between the regional sea ice variabilities across the Arctic uncovers a new source of predictability for spring BS sea ice prediction at 7-month lead time. A cross-validated linear regression prediction model using the Arctic Pacific sea ice dipole with 7-month lead time is demonstrated to have significant prediction skills with 0.54–0.85 anomaly correlation coefficients. The autumn sea ice dipole, manifested as sea ice retreat in the Beaufort and Chukchi Seas and expansion in the East Siberian and Laptev Seas, is primarily forced by preceding atmospheric shortwave anomalies from late spring to early autumn. The spring BS sea ice increases are mostly driven by an ocean-to-sea ice heat flux reduction in preceding months, associated with reduced horizontal ocean heat transport into the BS. The dynamical linkage between the two regional sea ice anomalies is suggested to involve positive stratospheric polar cap anomalies during autumn and winter, with its center slowly moving toward Greenland. The migration of the stratospheric anomalies is followed in midwinter by a negative North Atlantic Oscillation–like pattern in the troposphere, leading to reduced ocean heat transport into the BS and sea ice extent increase.
Dynamical Structures of Cross-Domain Forecast Error Covariance of a Simulated Tropical Cyclone in a Convection-Permitting Coupled Atmosphere–Ocean Model

Published: October 2020

Understanding the dynamics of the flow-dependent forecast error covariance across the air–sea interface is beneficial toward revealing the potential influences of strongly coupled data assimilation on tropical cyclone (TC) initialization in coupled models, and the fundamental dynamics associated with TC air–sea interactions. A 200-member ensemble of convection-permitting forecasts from a coupled atmosphere–ocean regional model is used to investigate the forecast error covariance across the oceanic and atmospheric domains during the rapid intensification of Hurricane Florence (2018). Forecast uncertainties in both atmospheric and oceanic domains, from an Eulerian perspective, increase with forecast lead time, mainly from TC displacement errors. In a storm-relative framework, the ensemble forecast uncertainties in both domains are predominantly caused by differences in the simulated storm intensity and structure. The largest ensemble spread in the atmospheric pressure, temperature, and wind fields can be found within the TC inner-core region. Alternatively, the largest ensemble spread in the upper-ocean currents and temperature fields are located along the cold wake behind the storm. Cross-domain ensemble correlations between simulated atmospheric (oceanic) observations and oceanic (atmospheric) state variables in the storm-relative coordinates are highly anisotropic, variable dependent, and ultimately driven by the dynamics of TC air–sea interactions. Meaningful and dynamically consistent cross-domain ensemble correlations suggest that it is possible to use atmospheric and oceanic observations to simultaneously update state variables associated with the coupled ocean–atmosphere prediction of TCs using strongly coupled data assimilation. Sensitivity experiments demonstrate that at least 60–80 ensemble members are required to represent physically consistent cross-domain correlations and minimize sampling errors.

Authors: Bueno Alicia , March Jose Ramon , Garcia Pilar , Cañibano Cristina , Ferruelo Antonio , Fernandez-Casado Jose Luis
Published: October 2020

Carotid plaque inflammation assessed by 2-deoxy-2-[18F]fluoro-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) and lipoprotein-associated phospholipase A2 (Lp-PLA2) levels are higher in symptomatic patients. The aim of this study was to assess correlations between 18F-FDG uptake on PET scan of carotid artery plaques, plasma levels of Lp-PLA2, and cerebrovascular symptoms. The study included 45 consecutive patients (22 symptomatic, 23 asymptomatic) with >70% carotid stenosis. Patients were examined by hybrid PET/CT, and maximum standardized uptake values (SUVmax) were recorded. Blood samples were obtained, and plasma was stored at −80 °C for subsequent Lp-PLA2 analysis. Symptomatic and asymptomatic patients showed no significant difference in classical cardiovascular risk factors. Asymptomatic carotid stenosis patients more frequently had a history of coronary artery disease ( P = .025) and peripheral artery disease ( P = .012). The symptomatic group had higher 18F-FDG uptake in carotid plaques ( P < .001), higher plasma Lp-PLA2 ( P < .01), and higher high-sensitive C-reactive protein ( P = .022). 2-Deoxy-2-[18F]fluoro-D-glucose uptake on PET/CT and plasma Lp-PLA2 show a statistically significant association with the symptomatic status of carotid plaques.
Flexible Endoscopic Evaluation of Swallowing in Breastfeeding Infants With Laryngomalacia: Observed Clinical and Endoscopic Changes With Alteration of Infant Positioning at the Breast
Authors: Mills Nikki , Keesing Melissa , Geddes Donna , Mirjalili Seyed Ali
Published: October 2020

Objectives:

This retrospective cohort study uses endoscopic assessment of the pharyngeal phase of swallowing in infants with laryngomalacia, to ascertain the impact of infant positioning on airway compromise and fluid dynamics during breastfeeding. The study aims to identify whether modification of infant positioning at the breast may improve the possibility of safe, successful breastfeeding in infants with laryngomalacia and concurrent breastfeeding difficulty.

Methods:

Twenty-three infants referred for noisy breathing and difficulty feeding were assessed with flexible endoscopic evaluation of swallowing (FEES) during breastfeeding. All had endoscopically confirmed laryngomalacia. During FEES, observations were made of clinical signs of airway compromise as well as endoscopically observable anatomical features and swallowing dynamics during breastfeeding, including tongue base position, view of laryngeal inlet and vocal folds, dynamic supraglottic soft tissue collapse, timing of milk flow into pyriform fossae/hypopharynx relative to sucking, and presence of penetration and/or aspiration. If airway and/or swallowing compromise was present, the infant’s initial position at the breast was altered from supine or semi lateral decubitus position to semi-prone, with a description of the clinical and endoscopically observable changes that subsequently occurred.

Results:

Signs of dynamic airway obstruction and/or compromised airway protection with swallowing were present in 20 of the 23 infants (87%) in their initial supine or semi lateral decubitus position. These 20 infants were repositioned to semi-prone, with improvement and/or resolution of stridor and an improved ability to maintain latch in all infants. Continued endoscopic evaluation following positional change was possible in 16 infants, identifying anterior positioning of the tongue base, reduced dynamic supraglottic tissue collapse, reduced volume of milk flow into pyriform fossae during pauses in sucking and resolution of penetration and aspiration.

Conclusion:

This study has shown how alteration of breastfeeding position to semi-prone may improve dynamic airway obstruction and reduce aspiration risk in infants with laryngomalacia.
Simulation and experimental research based on carrier gas flow rate on the influence of four-channel coaxial nozzle flow field
Authors: Guo Shi Rui , Yin Qian Qian , Cui Lu Jun , Li Xiao Lei , Cui Ying Hao , Zheng Bo , Cao Yan Long , Zeng Wen Han
Published: October 2020

This paper investigates the influence of carrier gas flow on the external flow field of coaxial powder feeding nozzle. FLUENT software was adopted to establish gas-solid two-phase flow. The simulation of powder stream field under different carrier gas flow was also carried out. Results show that the larger the flow of carrier gas is, the higher the gas flow field velocity at the nozzle outlet is. At the same time, the concentration at the convergence point is lower, and the convergent point is maintained at 0.015 m. Under the condition of 4 L/min, the powder flow convergence is good. When it exceeds 4 L/min, powder spot diameter increases. The experiment of powder aggregation and laser cladding forming were completed, which shows that the forming effect is the best one under the condition of 4 L/min. It is consistent with the simulation analysis results and has a high reference to the optimization of the process parameters of coaxial nozzle.
Impossible Allies? When History and Security Collide: South Korea—Japan Relations in Context
Authors: Bae Joonbum
Published: October 2020

To what degree are historical animosities regarding another country relevant for foreign policy in the face of changes in the security environment? This paper seeks to answer this question in the context of Korea–Japan relations. While pundits have pointed to the Korean public’s negative views of Japan—rooted in the colonial experience—as the explanation for the lack of cooperation between Japan and Korea in the security field, this paper argues changes in the level of common external threat can shift the public’s priorities from perceived historical injustices toward the needs of security. Surveys from the period when the security environment was shifting markedly—the final years of the Cold War (1986–1990)—reveal that public opinion regarding Japan relative to other powers in the region began to deteriorate only after the security environment improved, pointing to a limit to the extent that “history” trumps security.
Consumers’ Preference for User-Designed Versus Designer-Designed Products: The Moderating Role of Power Distance Belief
Authors: Song Xiaobing , Jung Jihye , Zhang Yinlong
Published: October 2020

Anecdotal evidence and extant research show that consumers can prefer both user-designed and designer-designed products. However, the factors that moderate such preferences are not well understood. The authors posit power distance belief (PDB) as a moderator such that low-PDB consumers prefer user-designed to designer-designed products because they identify more with user-driven companies. In contrast, high-PDB consumers prefer designer-designed to user-designed products due to their stronger trust in designer-driven companies. Six studies examining power distance belief at both the country and individual levels provide convergent support for the proposed moderating effect of PDB and underlying mechanisms. Furthermore, the authors demonstrate that the interaction between design philosophy and PDB is more likely for low-complexity than high-complexity products.
Bereavement in Times of COVID-19: A Review and Theoretical Framework
Authors: Stroebe Margaret , Schut Henk
Published: October 2020

A review of the literature on adaptation to bereavement during the COVID-19 pandemic was conducted to assess the current state of knowledge. Scopus, Web of Science and Google Scholar databases were searched for studies published during the first 6 months of the COVID-19 outbreak. 44 articles were included in the review. Narrative synthesis showed that knowledge was largely based on expert assessments of prior bereavement research and professional experience; there is so far absence of empirical evidence linking features of COVID-19 bereavement situations to health outcomes. Severe negative consequences have been consistently predicted by authors. There is still relatively little consideration of positive or compensatory processes or the possibility that these could alleviate the effect of the shocking, traumatic circumstances. With two notable exceptions, there has been lack of attention to the role of theoretical models for guiding research and practice. A theoretical perspective (the Dual Process Model, DPM) was applied to the information derived from the available articles. Two features of the DPM framework illustrated its relevance: 1. It enables systematic assessment of the range of loss- and restoration-related challenges for the bereaved; 2. It speaks for extension of psychotherapeutic intervention to manage secondary, restoration- as well as primary, loss-oriented stressors; studies have demonstrated that this may increase the effectiveness of intervention. Directions for future research and DPM application are suggested.
Utility of DSM-5 Criteria for Internet Gaming Disorder
Authors: Carlisle Kristy
Published: October 2020

The American Psychiatric Association (APA) has called for further research on Internet Gaming Disorder (IGD) by placing it in Section III of the Diagnostic and Statistical Manual ( DSM-5). Research on prevalence, risk factors, and development of criteria for a diagnosis of IGD is mixed in the literature. This study sought to contribute to these topics by examining a diverse sample of Internet gamers ( N = 1,881) from around the world. Results showed a prevalence rate of 4.2%, with varying prevalence rates based on demographic characteristics. Significant risk factors for IGD included gender and hours spent gaming. Finally, frequency counts of IGD criteria showed significant differences between participants meeting IGD criteria and those not meeting criteria, as well as significant differences by gender and age. Low frequency counts and significant differences based on demographics point to criteria that may be less appropriate for a diagnosis, as well as considerations for diagnosing diverse populations. Limitations and future research are discussed.
English Language Teacher Education and the Multiliteracies Pedagogy: Constructing Complex Professional Knowledge and Identities
Authors: Maia Angélica Araújo de Melo
Published: October 2020

Contemporary literacy practices need to be addressed in school settings. That requires awareness by teachers and students of the cultural and linguistic diversity present in our cosmopolitan societies. In the field of English language teaching (ELT), one way of responding to such demand is engaging teachers with multiliteracies pedagogies throughout their professional preparation. Based on that assumption, this paper reports on a component experience of the Brazilian Government Program for Initial Teacher Education, where, in 2017, three teacher candidates planned and taught three English lessons using the multiliteracies pedagogy framework. It stands as a case study that seeks to identify the impacts of using multiliteracies pedagogy in a teacher education context, in terms of knowledge building and identity work. Teacher candidates engaged in a designing process of multimodal teaching materials and documented their experience in journals. Those items were used as data to investigate the impact of the pedagogy on teachers’ development, focusing on the following elements of design: reference, dialogue, structure, situations, and intention. Research findings suggest the positive impact of that experience, both as a source of professional knowledge and as a fruitful opportunity for teachers to change preconceptions about ELT.
Self-Regulated Learning Development in Undergraduate ESL Writing Classrooms: Teacher Feedback Versus Self-Assessment
Authors: Vasu Kayatri A/P , Mei Fung Yong , Nimehchisalem Vahid , Md Rashid Sabariah
Published: October 2020

In the English as a second language (ESL) research context, teachers are committed to ensuring that students are aware of their writing skills and the kinds of errors they make in their writing. This explains why teacher feedback is frequently practised in the writing classrooms. Self-assessment is another supplementary strategy that provides opportunity for ESL students to take control of their learning. This study investigated the effects of self-assessment and indirect teacher feedback on self-regulated learning (SRL). A quasi-experimental design with an embedded experimental model was used in this research. Three intact classes were randomly assigned to experimental and control groups. This study utilised both quantitative and qualitative data. The quantitative data were obtained through the Self-Regulation Strategy Inventory Self-Report. The qualitative data were derived from the SRL microanalytic protocol. The findings revealed that both self-assessment and indirect teacher feedback helped learners become more self-regulated. However, self-assessment reduced maladaptive behaviours more than indirect teacher feedback. This study concludes that self-assessment is an effective instructional practice that promotes SRL in terms of goal setting, strategy planning, strategy use, attribution and adaptive behaviour. It is recommended that self-assessment be part of an instructional practice rather than an alternative strategy in the writing class.
Rethinking ‘Peace’ in International Law and Politics From a Queer Feminist Perspective
Authors: Otto Dianne
Published: October 2020

What does peace mean in today’s world of endless wars? Why has the project of ‘universal peace’, so ardently hoped for by the drafters of the UN Charter in 1945, failed so profoundly? I reflect on these questions through three stories of peace. The first is told by a series of four stained-glass windows in the Peace Palace in The Hague; the second is of the world’s demilitarised zones; and the third of a peace community in Colombia. These stories provide a springboard to reflect on how we might rethink peace in the context of today’s world, drawing on feminist, queer and postcolonial analyses. My discussion exposes the limits of the UN Charter’s approach to peace, and the impossibility of its methods ever achieving ‘universal peace’. The Charter’s reliance on militarism and collective enforcement, as well as its commitment to peace as an evolutionary process, maintain rather than dismantle global hierarchies of domination. I also question the dualism of war and peace, which obscures much of the violence of what we call peace. The task of rethinking peace is urgent. To do so we need to go beyond the worlds we know, beyond the confines of law and the inevitability of quotidian hierarchies of gender, sexuality and race, to invent new methods of peace-making, outside the ‘frames of war’.
Bone Damage in Chronic Otitis Media
Authors: Kuczkowski Jerzy , Brzoznowski Wojciech , Nowicki Tomasz
Published: October 2020

The middle ear bone destruction in chronic otitis media is activated and regulated by inflammation. Chronic otitis media with granulation is a highly active inflammatory process in which many cytokines are released. The bone is degraded by osteoclasts but, at the same time, protected by cytokines, growth factors, adhesion molecules and osteotropic hormones. Tumor necrosis factor-α, interleukin (IL)-1, IL-6, and OPG/RANKL present in cholesteatoma and granulation accelerate bone lysis and increase the destructive effect on the middle ear.
Causes of Vocal Fold Paralysis
Authors: Wang Hsing-Won , Lu Cheng-Chieh , Chao Pin-Zhir , Lee Fei-Peng
Published: October 2020

Background:

Vocal fold paralysis (VFP) can result from a variety of diseases or surgeries and has various causes. This study determined concurrent etiologies in patients who were treated in a teaching hospital (tertiary medical center).

Methods:

A retrospective review of medical records of patients with VFP from September 2010 to December 2019 was performed to determine the etiology. Patients with laryngeal/hypopharyngeal malignancies, those with incomplete examination and follow-up data were excluded from the study. During the follow-ups, cases involving recovery were also excluded.

Results:

One hundred and ninety-four patients with a determined etiology were included: 113 males and 81 females. Unilateral VFP was present in 178 patients, and 16 presented with bilateral VFP. The causes of unilateral VFP were surgical for 61.3%, neoplastic for 17.5%, idiopathic for 10.3%, traumatic for 1.5%, central for 4.7%, cardiovascular for 2%, radiation-induced for 1.5%, and inflammatory for 1%. Thyroidectomy was the most common surgery for unilateral VFP and was the cause for 54 patients. Lung cancer was responsible for 15 cases and was the most common neoplastic etiology of unilateral VFP. For those who presented with bilateral VFP, surgery was the most common cause and accounted for 56.3% of the incidences. In terms of gender, surgery was the most common cause for both sexes, accounting for 62 of 113 male patients and 57 of 81 female patients. Four cases recovered during the follow-ups and these were excluded.

Conclusion:

Surgery and in particular, thyroidectomy, was the most common cause of VFP for these series. Central nervous system disorders were the cause of VFP (4.5%). Central nervous system disorders, especially cerebrovascular accidents that induced VFP, could not be neglected. Radiation-induced cranial nerve paralysis in the head and neck cancer was possible causes. The percentage for the causes of unilateral VFP, surgery increased and the percentage for neoplasm decreased for Taiwan.
Feasibility, Acceptability and Usage Patterns of a 24-Hour Mobile Phone Helpline Service for Women Discharged from a Mother-Baby Psychiatry Unit (MBU) in India
Authors: Ragesh G , Ganjekar Sundarnag , Thippeswamy Harish , Desai Geetha , Hamza Ameer , Chandra Prabha S
Published: October 2020

Background:

For women with perinatal mental illness, phone helplines may be a useful way of accessing help. This study assessed the feasibility, acceptability, limitations, and usage patterns of a helpline service for mothers discharged from a mother-baby psychiatry unit.

Methods:

Mothers discharged from a mother baby unit during an 18-month period were provided with a helpline number. A social worker answered the calls. Details of the calls, including the reasons and the interventions provided, were recorded. Feasibility and acceptability were assessed by calling all users and nonusers. Satisfaction with the helpline was recorded among users, and reasons for not calling were assessed among nonusers.

Results:

Among 113 mothers, 51 (45%) made 248 calls. Calls were regarding medication, sleep problems, planning pregnancies, symptom exacerbation, appointments, and suicidal ideation. Some calls were related to domestic violence ( n = 13, 5.24%), and infant health and breastfeeding ( n = 11, 4.44%). Seventy-six (67%, 44 callers and 32 noncallers) were contacted. The majority (41/44) of the callers found it useful: 91% said they got help, and 95% said they would recommend it to others. However, language difficulties (9%) and technical problems (5%) were reported. Among the noncallers, the majority reported having experienced no problem related to mental health or had contacted a doctor. However, of the noncallers, one woman died of suicide, did not have access to a phone, and the family did not choose to call.

Conclusions:

Helpline phone service appears to be feasible and acceptable and can be adapted in other mother-baby psychiatry units in low and middle-income countries. However, in some women, the nonavailability of a phone may be a limiting factor.
Income Generation Programs for Persons with Mental Health Challenges: Practices from 13 Indian Mental Health Rehabilitation Centers
Authors: Roy Amrita , Jayarajan Deepak , Sivakumar Thanapal
Published: October 2020

Background:

In India, mental health rehabilitation centers run income generation programs (IGP) for therapeutic engagement, skills training, and income generation of clients. The centers have evolved IGP models relevant to their settings. There is a paucity of published literature on practices employed by the centers.

Methods:

This paper compiles data gathered from visits to 13 centers between November 2018 and April 2019. Information was collected through observation and interviews with staff involved in IGP, using a semi-structured pro forma designed for study.

Results:

Most centers were based in south India ( n = 11) and urban areas ( n = 12). Each center ran two to seven IGP. Each center involved 20–50 clients in IGP. Clients involved in IGP were aged 20–60 years. The centers ran a range of IGP, including the manufacturing of household consumables, paper products, textile products, handicraft products, food products, and jute products; animal husbandry and horticulture initiatives; and running cafeterias and petty shops. IGP were mostly selected based on market demand and sales value of products ( n = 11); ease of doing ( n = 5); interests, abilities, exposure, and experience of clients ( n = 5); and availability of resources ( n = 3). Products were priced primarily to cover input and labor costs ( n = 8), and many centers sold products below the market rates ( n = 5). Running stalls during public events was a common strategy for the sale of products ( n = 9). Personal contacts and “word of mouth” publicity were used for advertisement ( n = 6). Four centers involved family members in IGP.

Conclusion:

The nature of IGP varied in terms of setting, available resources, and profile of clients availing the services. Marketing and sales were a challenge. A supportive framework of policies and schemes is essential to promote IGP at mental health rehabilitation centers. This report may be helpful for professionals and centers planning to set up an IGP.
Cognitive Screening Tool for Geriatrics: A Retrospective Observational Study on the Correlation of the Scores in 30-Point Clock Face Test and MMSE
Authors: Bouati Noureddine , Drevet Sabine , Zerhouni Nabil , Bioteau Catherine , Mitha Nathalie , Gavazzi Gaëtan
Published: October 2020

Background:

Over the past 30 years, the clock drawing test (CDT) has generated considerable interest due to its usefulness in the early detection of cognitive impairments, particularly those seen in neurodegenerative dementias (including Alzheimer’s disease), vascular dementia, and mixed dementia. The present study aimed to determine whether the results of the “30-Point Clock Face Test” (CFT-30), a standardized version of the CDT that uses a 30-point scale, correlate with those of the Mini-Mental State Examination (MMSE).

Methods:

This is a retrospective, observational study. All patients hospitalized in a Hospital-University Clinic Geriatrics Unit (Grenoble Alpes University Hospital, Grenoble, France), from January 1, 2017, to December 31, 2018, were included. Patient data and scores were retrieved from hospital archives, and the results of the two tests of interest, MMSE and the CFT-30, were analyzed.

Results:

We included 214 patients aged ≥75 years. The mean ± SD age was 86.4 ± 5.6 years, and 68.7% were female. A strongly positive, significant correlation was seen between the CFT-30 and MMSE ( r = 0.73, P < 0.001) scores. The total scores obtained by these two tests were identical ( t = 1.22, P = 0.22).

Conclusion:

CFT-30 is a good complement to the tools usually used in the investigation of cognitive impairments in older people. In addition to its metrological qualities, the standardized and normalized CFT-30 is extremely simple and very fast to use.
Emotion and its Management: The Lens of Language and Social Psychology
Authors: Gallois Cindy , Vanman Eric J. , Kalokerinos Elise K. , Greenaway Katharine H.
Published: October 2020

In this paper, we briefly review the large research literature on emotion in social psychology, and show how it is now firmly embedded in language and communication. As a springboard, we look at the history of emotion studies in JLSP. Then, we consider theory and methodology, and evaluate how standard and more recent methods of measurement have led to new ways of looking at the communication of emotion, including in real-life contexts. We conclude with suggestions for a research agenda that takes the study of emotion forward into the heartland of research in language and social psychology.

Published: October 2020

Background

Coordination of various physical and mental aspects of individuals, including the ability to control difficult conditions and situations has an effect in the prevention and development of various diseases, such as diabetes, and the improvement of the quality of life. Therefore, the purpose of this study was is to determine the effect of emotional intelligence on the quality of life of elderly diabetic patients.

Methods

This study was conducted in 2018. The statistical population in this cross-sectional study consisted of elderly people referred to the health centers of Kermanshah province in western Iran, who were divided via available sampling into two groups with diabetes and without diabetes. Data gathering tools were a couple of LIPAD Quality of Life and Shrink Emotional Intelligence standard questionnaires. The Data was analysed using software SPSS, 23 th version. Tests were used (T-test, Chi-square, Anova and regression).

Results

Most of them were male (52.72%) and the mean age of the patients was 65.01(±6.08) years old and married. The quality of life score in diabetics and non-diabetics was respectively 51.9 and 50.37 with a standard deviation of 17.73 and 20.54. The mean total score of emotional intelligence in the elderly with diabetes was 99.42 with a standard deviation of 10.37 and non-diabetic subjects were 97.18 with a standard deviation of 18.4.

Conclusion

There was no significant difference between the mean scores of quality of life (0.652) and emotional intelligence (0.421) in diabetic and non-diabetic individuals. But, the emotional intelligence has an effect on the quality of life of the elderly people.
Extent and Predictors of Decision Regret among Informal Caregivers Making Decisions for a Loved One: A Systematic Review
Authors: Elidor Hélène , Adekpedjou Rhéda , Zomahoun Hervé Tchala Vignon , Ben Charif Ali , Agbadjé Titilayo Tatiana , Rheault Nathalie , Légaré France
Published: October 2020

Background

Informal caregivers often serve as decision makers for dependent or vulnerable individuals facing health care decisions. Decision regret is one of the most prevalent outcomes reported by informal caregivers who have made such decisions.

Objective

To examine levels of decision regret and its predictors among informal caregivers who have made health-related decisions for a loved one.

Data sources

We performed a systematic search of Embase, MEDLINE, Web of Science, and Google Scholar up to November 2018. Participants were informal caregivers, and the outcome was decision regret as measured using the Decision Regret Scale (DRS).

Review methods

Two reviewers independently selected eligible studies, extracted data, and assessed the methodological quality of studies using the Mixed Methods Appraisal Tool. We performed a narrative synthesis and presented predictors of decision regret using a conceptual framework, dividing the predictors into decision antecedents, decision-making process, and decision outcomes.

Results

We included 16 of 3003 studies identified. Most studies ( n = 13) reported a mean DRS score ranging from 7.0 to 32.3 out of 100 (median = 14.3). The methodological quality of studies was acceptable. We organized predictors and their estimated effects (β) or odds ratio (OR) with 95% confidence interval (CI) as follows: decision antecedents (e.g., caregivers’ desire to avoid the decision, OR 2.07, 95% CI [1.04–4.12], P = 0.04), decision-making process (e.g., caregivers’ perception of effective decision making, β = 0.49 [0.05, 0.93], P < 0.01), and decision outcomes (e.g., incontinence, OR = 4.4 [1.1, 18.1], P < 0.001).

Conclusions

This review shows that informal caregivers’ level of decision regret is generally low but is high for some decisions. We also identified predictors of regret during different stages of the decision-making process. These findings may guide future research on improving caregivers’ experiences.
High-resolution MRI assessment of optic nerve sheath diameter in adults: optic nerve sheath variation and a new diagnostic tool for intracranial hypertension
Authors: Zheng Ying-mei , Hao Da-peng , Tang Guo-zhang , Zhou Rui-zhi , Pang Jing , Dong Cheng
Published: October 2020

Background

Assessment of optic nerve sheath diameter (ONSD) is a non-invasive measure of intracranial pressure (ICP). However, it is not clear whether healthy individuals exhibit ONSD variation or whether factors other than ICP affect the ONSD.

Purpose

To investigate whether ONSD was correlated with age, sex, height, weight, eyeball transverse diameter (ETD), or body mass index (BMI), and to develop a new diagnostic model to increase the diagnostic accuracy of intracranial hypertension (IH).

Material and Methods

A total of 145 relatively healthy adults and 40 patients with acute IH who underwent high-resolution magnetic resonance imaging (MRI) were enrolled in this study. Linear regression analyses were used to determine the relationship between ONSD and these variables. If correlations were identified, an index ONSDΔ removing variables effects was calculated. ROC analysis was used to assess the IH predictive value of ONSDΔ in terms of sensitivity and specificity.

Results

In relatively healthy adults, there was a correlation between ONSD and BMI ( P = 0.002), which can be presented as an index ONSDΔ. The ONSDΔ model better predicted IH than the ONSD model ( P = 0.035), with a sensitivity of 70.00%, a specificity of 71.72%, and an AUC of 0.755.

Conclusion

A correlation between ONSD and body mass index (BMI) was found using high-resolution MRI. This result indicates that the effects of BMI should be considered along with the ONSD during ICP monitoring. Meanwhile, the index ONSDΔ was better than the ONSD in predicting IH and could be used to obtain a more precise estimation of ICP.
Exploring the Elements and Determinants of the Value of Time for Manual Driving and Autonomous Driving using a Qualitative Approach
Authors: Kolarova Viktoriya
Published: October 2020

Autonomous driving is expected to change individual travel behavior significantly. The main reason postulated is an increase in comfort and feasibility of on-board activities which will potentially change the way people perceive time spent in a vehicle and consequently their mode preferences. Understanding how value of time (VoT) might change and what will determine such change can be crucial when assessing the impact of vehicle automation. Recent studies address potential changes that automation might have on VoT based on analyses of time use and perception in current modes of transport or focusing only on the utility of driving autonomously. However, there is a lack of research addressing both—the utility of car driving compared with the utility of riding autonomously—from the user perspective. To address this research question, focus group discussions with car drivers were conducted. The data was analyzed using a thematic qualitative text analysis. The results suggest that the utility of car driving today, including aspects of driving pleasure, various (passive) activities performed in the car, and also driving as an activity itself, will counterbalance to a certain extent the effect of the benefits of autonomous driving, such as improved travel experience and feasibility of activities. Moreover, context-related and individual characteristics shape these effects. This paper summarizes the main study results, including potential short- and long-term travel behavior changes resulting from the availability of autonomous driving. Lastly, implications from the qualitative research for quantitative studies on value of travel time savings for autonomous vehicles are discussed.
Influence of Lane Width on Bus Crashes
Authors: Dai Boya , Hudson Joan G. , Ettelman Ben , Park Eun Sug
Published: October 2020

Motor vehicle lane width is often reduced to accommodate non-motorized transportation and increase safety for all road users—in many cases from the conventional width of 12 ft to as narrow as 9–10 ft. Although it has not been a significant issue for passenger car drivers, the narrower lanes pose concerns for bus transit operators. This study analyzed data from the Capital Metropolitan Transportation Authority, the public transit provider in the Austin, Texas, area, to evaluate the influence of narrow travel lanes on bus crashes. It included a comprehensive review of literature, interviews with cities and transit agencies, an analysis to determine the correlation between lane width and target bus crashes (sideswipe, fixed-object, and mirror-to-mirror), and an assessment of the impact of a curb or parked car immediately adjacent to the narrow outside lane on bus crashes. The literature review and interview findings support a standard lane width of 11–12 ft for bus routes. The statistical analysis suggested that more target bus crashes were associated with narrower lane widths. A curb or parked car immediately adjacent to the outside lane was problematic regardless of whether the outside lane was less than 12 ft or not. Though narrower lane width could contribute to fewer catastrophic crashes because of the slower speeds, it increases the likelihood of certain bus crashes. Cities and transit agencies should work together to determine lane width to balance the needs of all road users.
Beyond the Capitalist Workplace
Authors: Panayotakis Costas
Published: October 2020

This article analyzes the public and household sectors of the economy as sites of surplus production within contemporary capitalist societies. It also shows how the coexistence of structurally distinct spheres of surplus production creates divisions among workers in the private, public, and household sectors of the economy, thus amplifying the racial, gender, and other divisions that have often in the past kept working people divided. Fueling these cross-sector divisions is the appearance that private-sector workers are paid for their labor rather than for their labor power. Thus, this article also explores an implication of this appearance, which Karl Marx, the thinker who did the most to expose it, did not himself explore.
The Lockean Law of Restitution
Authors: Jarrett David
Published: October 2020

This article argues—in contrast to the claims of right-libertarians—that the Lockean thesis of justice in property seems to entail much egalitarian property redistribution. It starts by outlining what the Lockean thesis of justice in property is. It then argues that a Lockean version of the law of restitution is a reasonable way to approach the problem of holdings which were not gained in line with Lockean justice. Furthermore, according to this law, property which has unknown rightful owners should ideally be redistributed in an egalitarian manner among everybody in the world. In addition, due to the history of Lockean injustice throughout the world (e.g., feudalism and colonialism), it appears that much property in the world should be redistributed in an egalitarian manner.
The Intersecting Influence of Age and Performance Stereotypes on Physical and Psychological Aspects of Stair Navigation in Older Adults
Authors: Stone Rachael C. , Gage William H. , Baker Joseph
Published: October 2020

Negative age-stereotypes can have widespread effects on older adult functionality; however, no research has explored psychophysical aspects of stair navigation after exposure to stereotype priming. The present study examined self-efficacy and biomechanics related to stair navigation in older adults ( N = 90). Between-groups analyses revealed positively primed older adults ascended and descended the stairs significantly faster with greater velocity in the medio-lateral plane than older adults who received a negative prime or controls ( p < .017). Moreover, negatively primed older adults rated their stair self-efficacy significantly lower compared with the control and positively primed groups ( p < .017). These results suggest positively primed older adults can navigate stairs with more confidence, quickness, and efficiency. With implications for interventions aimed at maintaining older adult functionality, the present study highlights the potential benefits of positive age-stereotypes, especially related to challenging physical tasks.
Stalking and Other Forms of Dating Violence: Lessons Learned from You in Relation to Cyber Safety
Authors: Chugh Ritesh , Guggisberg Marika
Published: October 2020

Often, individuals share private information on social media, being unaware of online dangers. You, a popular psychological thriller series on Netflix, raises issues of stalking behaviors through social media as part of a pattern of dating violence. Using a qualitative content analysis approach, this study examined how social media is used for erotic stalking, dating violence, and cyber safety awareness (or lack thereof) in You. The researchers analyzed all 10 episodes of the first season of You independently, taking notes. A combined in-depth analysis included discussions of messages and meanings resulting in three overarching themes: obsessive online and in-person erotic stalking, controlling behaviors in the context of the dating relationship, and an apparent indifference about cyber safety with oversharing of personal information on social media, which was exploited by the lead protagonist. You raises important concerns including inappropriate dating behaviors such as stalking, coercive control, violence, and questionable masculine attitudes, which are interwoven with an apparent lack of knowledge and understanding in relation to cyber safety. We concluded that raising awareness of the importance of online safety and security in the context of a dating relationship is imperative and that You can be used as an educational tool.
On Spiritualist Workers: Healing and Divining through Tarot and the Metaphysical
Authors: Lavin Melissa F.
Published: October 2020

In the following article, I explore how tarot card readers (and other spiritualist workers) “control the future” to heal and empower their clients, emphasizing the porous roles of therapy and advocacy that assorted “psychics” perform. I examine how these workers navigate interactional trials, including misassigned identity, ethical challenges, and interactional boundaries in readings at psychic fairs and in private practice. Tarot card readers and other “psychics” are independent contractors and (self)help workers that are cast aside from both science and religion, labor outside of conventional credentialing systems, and are reputationally marginalized. I argue that this cultural and structural marginalization allows these “libertarian spiritualist” workers to construct amalgamate identities, exercising role flexibility as readers and querents, and healers and survivors.
Integrating the circular economy into engineering programs in India: A study of students’ familiarity with the concept
Authors: Venugopal Pingali , Kour Harwinder
Published: October 2020

Human production and consumption activities are depleting the earth’s resources faster than they are being replenished. The Global Footprint network estimates “Earth Overshoot Day 2020” (the day the use of natural resources during the year crosses the regeneration capacity for the year) to be 22 August. A shift from linear to circular economy (CE) practices offers an alternative approach that favors environmental conservation, integrating economic growth with environmental protection. While it is important to educate engineering students about sustainable models, environmental education is mandatory in India and a 6-month module introduces various concepts in all university programs. This article examines the extent of familiarity of Indian engineering students with the concept of a circular economy. A two-phase methodology was used, with 148 students of a National Institute of Technology participating in the study. In Phase 1, which focused on the students’ awareness of the CE, it was found that only a third were familiar with the concept. In Phase 2 the students, after having had the concept explained to them, identified possible barriers to incorporating it into the syllabus. The implications of integrating the concept with the syllabus are discussed.
Two-parameter Lie convective Casson fluid scale study with MHD, joule heating and viscous dissipation influences
Authors: Nazim Tufail Muhammad , Saleem Musharafa , Ali Chaudhry Qasim
Published: October 2020

The model encountered an unsteady laminar and two-dimensional convective flow of Casson fluid passing through an inclined permeable vertical stretching sheet. The momentum, thermal and concentrated boundary layers (BLs) are used to analyze the unsteady effects of magnetohydrodynamics (MHD) (neglecting induced magnetic field), viscous dissipation, Joule heating and chemical reactions. The governed partial differential equations (PDEs) of the model are reduced to the ordinary differential equations (ODEs). The ξ and χ are selected as the two parameters of the scaling transformations. By using bvp4c with MATLAB, the ODEs are solved numerically and represent their results through the graphs and tables. After the non-dimensionalizing of the equations system, we get the emerging dimensionless parameters. The concentration process was enhanced by the Casson fluid parameter but it reduced the fluid flow and thermal transfer that can be found through the graphical results. The effect of Buoyancy is highlighted as it reduced the velocity profile function, but it is a growing function of the thermal and concentrated profiles. The physical quantities are integrated through the table and graphical analysis. In the center of the wall, the number Shx versus Sc decreases, but at the end it increases.

Published: October 2020

This paper analyzes the effects of propeller flow on the linear coupled longitudinal and lateral dynamics of a 150 mm wingspan fixed wing micro air vehicle (MAV). The effects propeller flow on the lift, drag, pitching moment and side force is obtained through wind tunnel tests. The aerodynamic forces and moments are modeled as a function of angle of attack, sideslip angle, control surface deflection and propeller rotation per minute. The nonlinear six degrees of freedom model is linearized about straight and constant altitude flight conditions for different trim airspeed to obtain linear coupled longitudinal and lateral state space model. The eigenvalues and eigenvectors of linear coupled longitudinal and lateral state space model are compared with and without propeller flow effects. The variation in the natural frequencies and damping ratios of short period mode, phugoid mode and Dutch roll mode are analyzed for various trim airspeed. An increase in the natural frequency is observed for phugoid mode and Dutch roll mode with propeller effects. The stability of the spiral mode is enhanced by the propeller flow and also the response of the roll subsidence mode is faster with propeller effects. Detailed analysis of eigenvalues and eigenvectors shows the importance of incorporating propeller flow in analyzing the dynamics of the MAV.
