Physician Utilization of a Universal Psychosocial Screening Protocol in Pediatric Primary Care
Authors: Shellman Alison B. , Meinert Allison C. , Curtis David F.
Published: April 2019

This study evaluated physicians’ utilization of a universal psychosocial screening protocol within a pediatric primary care setting. Pediatricians (n = 20) adopted a multitiered screening algorithm using the Pediatric Symptom Checklist-17 (PSC-17) within well-child checkups (WCC) for children, ages 7 and 11 years. Descriptive analyses were performed to evaluate the initial 3 years of physician screening protocol implementation to: (1) determine frequency and proportion of use and (2) examine patient outcomes associated with accessing behavioral health care. Physicians frequently initiated the protocol, administering the PSC-17 within 3678 WCC encounters, with frequency progressively increasing over the 3-year period. Results highlighted elements of screener utilization, cost-effectiveness, screening algorithm fidelity, and prevalence of psychosocial concerns identified. Secondary implementation challenges were observed after initial screening, specific to implementation of prescribed follow-up procedures. Primary care behavioral health collaborations appear helpful for improving universal screening utilization and cost-effectiveness, and for ensuring children with psychosocial problems are identified early and directed to follow-up care as needed.
Comparison of 3 Surveillance Methods to Detect Potential Controlled Substance Diversion in an Academic Medical Center
Authors: Derington Catherine G. , Lopez Ben R. , Weber Robert J. , Tubbs Crystal R.
Published: April 2019

Objectives: To compare 3 methods of detecting potential diversion of controlled substances (CS) by health care personnel from inpatient units in a large, academic medical center. Methods: Three different reports were retrospectively analyzed and evaluated to determine which employees are “high-risk” for diversion over a 30-day period using defined criteria. Reports were derived from automated dispensing machines (ADMs), purchased third-party software (TPS), and the electronic health record (EHR). The primary outcome was the percentage of employees in each report who were deemed to be high-risk for CS diversion (positive predictive value [PPV]). Secondary outcomes included the number of false positives and description of high-risk users on each report. Descriptive statistics were used to analyze differences between methods. Results: The PPV was highly variable between reports. The PPVs among the ADM, TPS, and EHR reports were 3.28%, 6.82%, and 23.88%, respectively. False positives were high among all reports (96.72%, 93.18%, and 76.12% for the ADM, TPS, and EHR reports, respectively). Conclusions: A report from the EHR has the highest PPV to detect high-risk employees who may be diverting CS. However, false positives were high for all reports, indicating that significant improvements are needed in the development of accurate and reliable software to detect potential and actual CS diversion.

Published: April 2019

Objective:

This study presents anthropometric data for individuals with high body mass index (BMI). Modified anthropometric dimensions were also developed to address the challenges of obtaining accurate and repeatable data for this population segment.

Background:

The prevalence of obesity affects approximately 40% of the U.S. adult population. Anthropometric data are needed to guide product design and safety, but few individuals with high BMI have been measured in available datasets.

Method:

Anthropometric data for a convenience sample of 288 adults with high BMI (≥30 kg/m2) were collected. To increase participation and minimize participant discomfort, measurements were collected at three bariatric weight loss clinics and one academic research institution.

Results:

The current obese cohort are heavier than the U.S. general population, with a difference in mean body weight of 47 kg for women and 56 kg for men. The obese cohort are also heavier and have a higher BMI compared with the NIOSH (National Institute for Occupational Safety and Health) truck driver population. Waist circumferential measures of the current obese cohort were larger than women or men in either population compared, a result indicative of meaningful body shape differences.

Conclusion:

To our knowledge, this study is the first to collect anthropometric data for the obese population segment and conduct comparisons to the U.S. general population and available occupational databases. The obese cohort differed substantially with respect to the distributions of anthropometric variables.

Application:

These data provide insights about the obese population segment that are relevant to product design, and establish a foundation for future data collection efforts.
Teacher quality gaps in U.S. public schools: Trends, sources, and implications
Authors: Goldhaber Dan , Quince Vanessa , Theobald Roddy
Published: April 2019

Empirical evidence shows that disadvantaged students tend to have less-qualified and less-effective teachers than their more-advantaged peers. These teacher quality gaps (TQGs), which have existed for decades and across many measures of student disadvantage and teacher quality, are an important factor explaining student achievement gaps between advantaged and disadvantaged students. Research by Dan Goldhaber, Vanessa Quince, and Roddy Theobald — focusing on the sources of TQGs across different states and measures of teacher quality — suggests that policy makers should consider both the setting and the type of gap they wish to prioritize when designing policies to address TQGs.

Beyond drink, drainage and divorce? What the Sociological Society did for British sociology
Authors: Panayotova Plamena
Published: April 2019

This article improves upon our current understanding of the Sociological Society’s contributions to the development of sociology in Britain. It challenges the assessment of the Society’s legacy made by Philip Abrams in 1968 and the more recent conclusions reached by scholars who contributed to a debate published in The Sociological Review in 2007. The article is built on original findings garnered from empirical research undertaken at The Sociological Review’s archives in Keele. It shows that, despite achieving some results in its attempts to introduce a particular type of sociology into Britain, the influence of the Society in establishing, both institutionally and intellectually, a sociological tradition was largely unsuccessful. A limited legacy, however, does not mean that the history of the Society is of little importance in the history of sociology in this country; on the contrary, as this article attempts to highlight, the Society deserves a critical examination precisely because of its limited legacy.
Effects of harvesting and ginning practices on Southern High Plains cotton: fiber quality
Authors: Wanjura John D , Armijo Carlos B , Delhom Christopher D , Boman Randal K , Faulkner William B , Holt Gregory A , Pelletier Mathew G
Published: April 2019

The lint yield and fiber quality of cotton produced in the Southern High Plains of the USA have improved over the last decade, renewing interest in finding harvest and ginning practices that better preserve fiber quality. Previous research showed that picker harvesting and roller ginning may better preserve fiber quality, but conventional roller ginning was too slow to be adopted as the primary ginning system used for Upland cotton. Advancements in roller ginning technology have increased the ginning rate per unit width of rotary-knife roller gins to approximately equal that of saw gins. Research has shown that improvements in nep content and fiber length characteristics afforded by conventional roller ginning compared to saw ginning are maintained by the new high-speed roller gins (HSRGs). The objective of this work was to compare the fiber quality, seed quality, ginning rate, and lint turnout of Upland cotton produced in the Southern High Plains, harvested using a picker or a stripper, and ginned using saw or HSRG systems. The findings of this work indicate that the HSRG substantially improved the length characteristics of the Upland cultivars tested regardless of harvest method. Turnout was higher for the HSRG and for picker harvested cotton. Nep content was reduced for picker harvested cotton and the HSRG. The fiber length distribution and nep content improvements from the HSRG system make this fiber more attractive to ring spinning mills that produce high-count yarns for high-value products.
Assessing airport ground access by public transport in Chinese cities
Authors: Liu Xingjian
Published: April 2019

This article assesses airport ground access by public transport in China. Recent literature has highlighted the economic, environmental and social significance of airport ground access. Existing studies on airport ground access have predominately centred on North America and Europe and, to date, limited attempts have been made to assess the emerging Chinese market. Studies of urban and transport geography have detailed the shifting air connectivity of Chinese cities and the economic impacts, but have paid little attention to ground access to airports. We, therefore, assess the ground accessibility to major Chinese airports based on online map services. Specifically, we characterise airport ground access across entire cities, as well as comparing time and monetary costs for travelling between airports and city centres by private car and public transport. We conclude with suggestions for future research, and call for more systematic data collection related to airport ground access.
Effects of parent–child interaction training on children who are excessively exposed to digital devices: A pilot study
Authors: Sadeghi Saeid , Pouretemad Hamid Reza , Khosrowabadi Reza , Fathabadi Jalil , Nikbakht Sedighe
Published: April 2019

Objective

In the last decade, the use of digital devices among children has increased. This study examines the effects of parent–child interaction training on the amount of time children use digital devices, conflict and closeness in parent–child relationships, executive functions, and the electroencephalogram absolute power in children who excessively use the digital devices.

Method

The sample group consisted of 12 children (24 to 47 months) who spent more than half of their waking hours using digital devices. Parents were trained to intensive interaction with the child for two months. Electroencephalogram absolute power, parent–child interaction, the amount of time children use digital devices, and children’s executive function skills were assessed.

Results

Parent–child intensive interaction reduces the use of digital devices; decrease the conflicts and increase the closeness in parent–child relationships; decrease executive functioning problems; and increase the absolute power of alpha and alpha 2 (F3), beta 1 (F3), and beta and beta 2 (F3, Fp2).

Conclusion

These findings provide evidence of the negative effects of the excessive use of digital devices in children, the importance of parent–child interaction, and its positive impacts on cognitive and brain functions in children. It might contribute to better understand the importance of parent–child interaction in the early years.
Design and implementation of a test bed for building controls
Authors: Goyal Siddharth , Wang Weimin , Brambley Michael R
Published: April 2019

Advanced controls play an essential role toward the improvement of building operational efficiency and the integration of responsive loads in buildings for grid services. Ideally, control algorithms must be sufficiently tested and validated before they are applied on real systems. This paper presents the development and current state of such an evolving test bed to support and enable experiments on advanced controls for buildings. The test bed presented in this paper consists of nine operating buildings—which possess various types of equipment and systems having different control systems and communication mechanisms (e.g., media and protocols) used in building automation systems—on the Pacific Northwest National Laboratory campus. The test bed architecture is developed in such a way that (1) it supports interactions among the buildings and heterogeneous building components and systems, including both virtual and physical devices, e.g., heating, ventilating, and air-conditioning and lighting systems; (2) it can be easily reconfigured for different control topologies and methodologies, e.g., centralized and distributed; (3) it allows selection of communication protocols, communication media, and computation resources; and (4) it is part of a larger cyber-physical test bed that includes both physical and virtual assets on distributed renewable generation, energy storage, and power system assets.

Practical application: The test bed presented in this paper can be used by industry to develop and evaluate the performance of advanced control algorithms on real systems for buildings and buildings-to-grid applications. This provides practitioners an opportunity to test the applications and modify them accordingly based on their use cases and selection criteria, e.g., a controller modulating the temperature in a hospital will have different criterion as compared to an office building.

Developmental Stages of Reading Processes in Children who are Blind and Sighted
Authors: Steinman Bernard A. , LeJeune B. J. , Kimbrough B. T.
Published: April 2019

This article compares the development of print and braille reading in children who are blind and sighted in relation to Chall's stage model of reading development. Chall's model includes a prereading period, in which concepts are developed; middle stages, in which skills that are necessary for decoding text are developed; and later stages, which distinguish skilled readers on the basis of their highly developed schemata and cognitive skills that are necessary for effective comprehension and integration. The relevance of a developmental theory for directing training methods that facilitate braille literacy instruction is discussed.
Studies of Braille Reading Rates and Implications for the Unified English Braille Code
Authors: Wetzel Robin , Knowlton Marie
Published: April 2019

Reading rate data was collected from both print and braille readers in the areas of mathematics and literary braille. Literary braille data was collected for contracted and uncontracted braille text with dropped whole-word contractions and part-word contractions as they would appear in the Unified English Braille Code. No significant differences were found between contracted and uncontracted braille reading rates or between print and Nemeth oral reading rates. Reading rates in cells per second for mathematics were slower than for literary material in both print and braille.

Authors: Cimarolli Verena R. , Boerner Kathrin , Wang Shu-wen
Published: April 2019

This study explored if and how vision rehabilitation services address important life goals of young and middle-aged adults who are visually impaired. It found that services that teach functional skills and offer psychosocial therapeutic-type services were instrumental in addressing life goals and that independence-related goals were most often addressed, but leisure-related goals were least often addressed.

Published: April 2019

This study compared the test scores and time required by high school students who are blind, sighted, or have low vision to complete tests administered in written and oral formats. The quantitative results showed that the blind students performed better on multiple-choice tests in braille and needed more time while taking tests in braille. The interviews revealed inconsistent relationships between the students’ preferred media and performance.
Community Services, Needs, and Resources in Visual Impairment: A 21st Century Public Health Perspective
Authors: Di Stefano Anthony F. , Huebner Kathleen M. , Garber Missy , Smith Audrey J.
Published: April 2019

This article suggests that a 21st century public health perspective on community needs and resource mobilization in vision impairment be grounded in a holistic concept of the community. This perspective should recognize the nature and magnitude of blindness and visual impairment within the significant technological, demographic, political, and sociocultural changes that characterize today's complex community structures. These changing community dynamics are linked with strategies for organizing and mobilizing resources. The article concludes with three propositions and a call for political action to transform our currently fragmented system of providing services into an integrated strategy for the 21st century.
The Effects of Perceived Decision-Making Styles on Evaluations of Openness and Competence That Elicit Collaboration
Authors: Tsai Ming-Hong , Melia Nadhilla Velda , Hinsz Verlin B.
Published: April 2019

When interacting with a task partner, individuals often rely upon characteristics they infer about their partner to determine their level of collaboration with the partner. To explore social perception processes related to collaboration, we examined perceptions of an actor’s decision-making style as predictors. Using different methods in various research settings, we found that compared with perceptions of an actor’s intuitive decision-making style or of a nonspecific decision-making style, perceptions of an actor’s rational decision-making style were more positively associated with inferences of the actor’s openness and competence, both of which were in turn associated with the perceiver’s collaborative intention with the actor. Intentions to engage in mutual collaboration were also positively associated with performance in an idea generation task. Therefore, our research offers a novel illustration of how to enhance collaboration based on perceptions of openness and competence inferred from others’ rational rather than intuitive decision-making style.
Concept-LDA: Incorporating Babelfy into LDA for aspect extraction
Authors: Ekinci Ekin , İlhan Omurca Sevinç
Published: April 2019

Latent Dirichlet allocation (LDA) is one of the probabilistic topic models; it discovers the latent topic structure in a document collection. The basic assumption under LDA is that documents are viewed as a probabilistic mixture of latent topics; a topic has a probability distribution over words and each document is modelled on the basis of a bag-of-words model. The topic models such as LDA are sufficient in learning hidden topics but they do not take into account the deeper semantic knowledge of a document. In this article, we propose a novel method based on topic modelling to determine the latent aspects of online review documents. In the proposed model, which is called Concept-LDA, the feature space of reviews is enriched with the concepts and named entities, which are extracted from Babelfy to obtain topics that contain not only co-occurred words but also semantically related words. The performance in terms of topic coherence and topic quality is reported over 10 publicly available datasets, and it is demonstrated that Concept-LDA achieves better topic representations than an LDA model alone, as measured by topic coherence and F-measure. The learned topic representation by Concept-LDA leads to accurate and an easy aspect extraction task in an aspect-based sentiment analysis system.

Published: April 2019

The intricate sensorimotor neural circuits that control swallowing are heavily reliant on serotonin (5‐hydroxytryptamine [5‐HT]); however, the impact of 5‐HT deficiency on swallow function remains largely unexplored. We investigated this using mice deficient in tryptophan‐hydroxylase‐2 (TPH2), the enzyme catalyzing the rate‐limiting step in 5‐HT synthesis. Videofluoroscopy was utilized to characterize the swallowing function of TPH2 knockout (TPH2‐/‐) mice as compared with littermate controls (TPH2+/+). Results showed that 5‐HT deficiency altered all 3 stages of swallowing. As compared with controls, TPH2‐/‐ mice had significantly slower lick and swallow rates and faster esophageal transit times. Future studies with this model are necessary to determine if 5‐HT replacement may rescue abnormal swallowing function. If so, supplemental 5‐HT therapy may have vast applications for a large population of patients with a variety of neurologic disorders resulting in life‐diminishing dysphagia, particularly amyotrophic lateral sclerosis and Parkinson’s disease, for which 5‐HT deficiency is implicated in the disease pathogenesis.

Published: April 2019

While optical imaging with near‐infrared (NIR) fluorescent dye has been used in oncologic surgery, its use in the head and neck has not been established. We aimed to evaluate the feasibility of using NIR to visualize primary tumor and regional metastasis in head and neck malignancy. Patients undergoing resection of primary head and neck tumors were included in this pilot study. Each patient was injected with indocyanine green dye (ICG) the day prior to surgery. The VisionSense Iridium camera system was used to visualize the primary lesion, its margins, and neck dissection specimen intraoperatively. Fourteen patients were enrolled. Eighty‐six percent of primary tumors showed fluorescence as compared with surrounding tissues. ICG positivity showed 100% sensitivity for pathologic nodes in 7 neck dissection specimens; however, for 3 patients, nonpathologic nodes also showed ICG positivity. NIR imaging with ICG dye can be considered for intraoperative imaging of head and neck lesions.

Published: April 2019

This article contributes to theoretical discussions in the field of transnational media management research. We argue that investigating media companies’ activities abroad from a strategy-as-practice perspective can overcome shortcomings implied in research predominantly focusing on strategies applied by entire companies. This is especially valid in times of digitization where changing technological frameworks force media companies to internationalize and restructure their business models. Based on a comparative qualitative analysis of interviews with 34 international senior media managers, this article provides a typology of cross-border activities related to three types of motivations: economic, organizational and socio-political. Relating activities and motivations provides a useful heuristic to systematically compare activities of most diverse media companies beyond objectives such as profit and growth. This sheds light on processes of digitization as related to numerous emerging organizational activities abroad with yet unclear economic trade-offs.
Impaired Core Stability as a Risk Factor for the Development of Lower Extremity Overuse Injuries: A Prospective Cohort Study
Authors: De Blaiser Cedric , De Ridder Roel , Willems Tine , Vanden Bossche Luc , Danneels Lieven , Roosen Philip
Published: April 2019

Background:

Core stability has been suggested to influence lower extremity functioning and might contribute to the development of lower extremity overuse injuries. However, prospective studies to investigate this relationship are limited.

Purpose:

To research the role of different components of core stability as risk factors for the development of lower extremity overuse injuries.

Study Design:

Cohort study; Level of evidence, 2.

Methods:

A total of 142 first-year physical education students participated in this study. They were tested in 2015 and were prospectively followed for 1.5 years by means of a multilevel injury registration method. Three participants were excluded owing to physical complaints during testing. As such, 139 participants were included in the statistical analysis. At baseline, dynamic postural control, isometric core and hip muscle strength, core muscle endurance, core neuromuscular control and proprioception, and functional movement were measured for all participants. Competing risk regression analyses were performed to identify significant contributors to the development of lower extremity overuse injuries.

Results:

During the follow-up period, 34 (24%) of the 139 participants developed a lower extremity overuse injury. Significant predictive effects for an overuse injury were found for an increased side-by-side difference in dynamic postural control ( P = .038), decreased isometric hip extension:flexion strength ratio ( P = .046), and decreased abdominal core muscle endurance ( P = .032).

Conclusion:

This study identified measures for dynamic postural control, core muscle strength, and core muscle endurance as significant risk factors for the development of overuse injuries after statistical model building. However, core neuromuscular control and proprioception and functional movement might not allow clinicians to identify patients at risk. These accessible, reliable screening tools could be used in clinical practice with regard to screening and injury prevention for overuse injuries. Injury prediction based on this model needs to be done with caution given the low relative predictive accuracy (53%).
DACAmented Homecomings: A Brief Return to Mexico and the Reshaping of Bounded Solidarity Among Mixed-Status Latinx Families
Authors: Ruth Alissa , Estrada Emir
Published: April 2019

This study builds on the intergenerational family dynamics literature among mixed legal status families. Through in-depth interviews with beneficiaries of Deferred Action for Childhood Arrivals (DACA) who traveled to Mexico and their undocumented parents who stayed in the United States, we uncover how their journey back to their country of birth influenced their roles within their families and the immigrant community. DACA recipients experienced feelings of guilt when traveling back to Mexico and leaving their parents behind, but they adopted a new role of family ambassador and transnational mediator. Through this experience, they developed a greater empathy toward their parents’ sacrifices and reshaped their bounded solidarity with their parents and the immigrant community. As a result, they justify a movement away from personally identifying with the traditional Dreamer narrative.
Impaired Color Discrimination—A Specific Marker of Hallucinations in Lewy Body Disorders
Authors: Matar Elie , Phillips Joseph R. , Martens Kaylena A. Ehgoetz , Halliday Glenda M. , Lewis Simon J. G.
Published: April 2019

There is emerging evidence indicating that color discrimination impairments can predict the development of Lewy body dementia in patients with rapid eye movement sleep behavior disorder, Parkinson disease, and in patients with mild cognitive impairment. Despite this clear relationship, color vision deficits are not seen uniformly in patients with dementia with Lewy bodies (DLB), suggesting a more nuanced association with the underlying neuropathology. Visual hallucinations represent a discriminating feature of DLB, and recent evidence implicates visual pathway dysfunction as a significant contributor to this phenomenon. In this study, we examined the relationship between color vision impairment and visual hallucinations, along with other clinical and neuropsychological features in 24 well-characterized patients with DLB alongside 25 healthy controls. Color discrimination impairment was seen in 16 (67%) of 24 DLB participants with a higher error score relative to controls ( P = .001). We demonstrate for the first time a strong association between color discrimination errors on the Farnsworth-Munsell 100 hue test and both the presence and severity of hallucinatory symptoms in DLB based on clinician-derived ( P = .008) and questionnaire-derived ( P = .03) measures. Correlation with clinical and neuropsychological variables revealed that color discrimination is significantly related to visuospatial difficulties measured by the clock-drawing task ( P = .02) but not to global measures of cognition, motor severity, age, or disease duration in our cohort. Factor analysis confirmed a unique relationship between color discrimination, visual hallucinations, and visuospatial function. Our results suggest that color discrimination does not simply relate to dementia but rather indexes higher order perceptual deficits that may predict visual hallucinations in Lewy body disorders and share a common pathophysiological substrate.
Comparative study of effect of different coupling agent on mechanical properties and water absorption on wheat straw-reinforced polystyrene composites
Authors: Sahai RSN , Pardeshi RA
Published: April 2019

The present work deals with the effect of various treatments on the mechanical properties and water absorption of wheat straw (WS)-reinforced polystyrene (PS) composites. Four different surface treatments of the filler, that is, alkali treatment of WS by 20% sodium hydroxide (NaOH) solution, maleic anhydride (MA) treatment of WS by 2% MA solution, WS treatment with 1% silane (ATS) and WS treatment with 20% NaOH and 1% silane, with 5–25% filler loading were carried out. There is an enhancement in tensile modulus, impact strength and water absorption and a decrease in tensile strength of WS fiber-filled PS composite with an enhancement in fiber loading when it is treated with 20% NaOH, 2% MA, and 1% silane. There is an enhancement in tensile strength, tensile modulus, Izod impact strength, and water absorption value when the WS fiber is treated with 20% NaOH and 1% silane, with an enhancement in fiber loading. Treatment with 20% NaOH and 1% silane exhibits better results as compared to the rest of the surface treatments.
A Case Report of Serotonin Syndrome in a Patient on Selective Serotonin Reuptake Inhibitor (SSRI) Monotherapy
Authors: Hudd Timothy R. , Blake Christie S. , Rimola-Dejesus Yahiada , Nguyen Thu-Trang , Zaiken Kathy
Published: April 2019

Introduction:

Paroxetine is a selective serotonin reuptake inhibitor (SSRI) with several indications, one of which is for depression. We present a case of probable paroxetine-induced serotonin syndrome.

Case Summary:

A 21-year-old female with a history of generalized anxiety disorder and major depression presented with increased depressive symptoms over several months while taking fluoxetine 20 mg daily. Fluoxetine was discontinued without taper and replaced with paroxetine 10 mg daily, along with hydroxyzine 50 mg twice daily as needed for anxiety. Within a week of starting the paroxetine, the patient reported increased anxiety, insomnia, and constant shaking. The paroxetine continued to be uptitrated over a 3-week period to a dose 30 mg due to unremitting depressive symptoms. One month later, the patient presented with tachycardia, generalized body aches, extreme fatigue, weakness, uncontrollable twitching, tremor, and hyperreflexia. A widespread burning sensation accompanied by random hot flashes without diaphoresis was also noted. Serotonin syndrome was diagnosed using the Hunters criteria. Paroxetine was discontinued, and the patient’s physical symptoms resolved within a week.

Discussion:

To date, only 5 cases of serotonin syndrome have been reported in patients receiving SSRI monotherapy at recommended therapeutic doses.

Authors: Sutin Angelina R. , Stephan Yannick , Aschwanden Damaris , Luchetti Martina , Strickhouser Jason E. , Terracciano Antonio
Published: April 2019

Objective: To examine the association between Five-Factor Model personality traits and how individuals evaluate a recent day in their lives (yesterday) and whether these evaluations mediate personality and cognitive function over time. Methods: Participants were a subsample from the Health and Retirement Study who completed personality measures in 2008/2010, the day evaluation in 2011, and cognitive tasks in 2012 ( N = 3,454). Results: Lower Neuroticism and Higher Extraversion, Openness, Agreeableness, and Conscientiousness were associated with a more engaging day, fewer negative feelings, better subjective health, and less time spent alone. Active engagement and subjective health were associated with cognitive function and mediated the prospective associations between Neuroticism, Openness, and Conscientiousness and cognitive function. Discussion: Personality is associated with how individuals evaluated their previous day, which contributes to cognition over time. The present research contributes to a mechanistic model that aims to identify pathways through which personality contributes to cognitive aging.
Numerical and experimental investigation of flow loss and flow structure of circular arc cambered plate blade cascade
Authors: Bian Tao , Shen Xin , Wang Bing , Feng Jun , Han Qianpeng
Published: April 2019

Due to the low production cost, circular arc blades are often applied to axial fans as outlet guide vane. At present, there is less available information focusing on the flow loss and flow structure of circular arc blades in the open literature. In particular, the influence of leading edge and trailing geometries on the aerodynamic performance of circular arc blades remains unknown. In this study, the circular arc blades edge with different leading edge and trailing edge are investigated and compared with numerical and experimental methods to detect the aerodynamic performance of the circular arc blades and the influence of their leading edge and trailing edge on the flow loss and flow structure. The flow loss and turning angle of both investigated blades are shown to dependent on the incidence angle. The flow structures of both blades are built on the basis of numerical and experimental oil-flow pictures. Additionally, the separation bubbles at the leading edge of the blade and the distribution of the flow loss on the measuring plane are shown and discussed.
FPO Emerging as the New MSME or Village Industry
Authors: Seshagiri Rao P. V. S.
Published: April 2019

The fledgling farmer producer organisations (FPO) have a statutory status but need better appreciation. They have a crucial role in doubling the farmer’s income. Seventy-five National Bank for Agriculture and Rural Development (NABARD) funded FPOs in Telangana (out of 129 FPOs among the thousands of enterprises in the state formed/funded up to the year 2018) were studied—starting with a numerical perspective before moving onto an entrepreneurial study in this desk-based analysis. The coverage has been found to be skewed in 59 (out of 584 ) mandals (blocks) in 23 (out of 31) districts in Telangana. The top as well as poorly performing three districts each have been identified for further action besides proposing the use of a metric of FPO density/1000 cultivators. It is also to be noted that eight districts (accounting for about a third of the cultivator population) have been left uncovered by the FPO activity (especially Hyderabad district which can be a crucible for unique and novel enterprises). The interactions of FPO-promoters and FPO-age have been studied. Their entrepreneurial activities have been examined and it was found to be diverse with little value addition in these and little service activity taken up. It seeks to further the argument that FPOs can be equated with micro, small and medium enterprises (MSMEs)/village industries so that benefits to industries also flow here. The author agrees with the results of the Global Entrepreneurship Monitor study regarding entrepreneurial behaviour. It is proposed to examine in a serial manner the growth, membership, financial stakes, etc. in the future studies for their greater understanding.
Modelling Customer Delight in Hotel Industry
Authors: Goswami Sinmoy , Sarma Mrinmoy K.
Published: April 2019

It is not an exaggeration that the present-day competitive environment calls for continuous and consistent delivery of customer delight in any sector of the business. The studies conducted by separate researchers across different settings suggest the existence of a common model sequencing the events that lead to customer delight. This study attempts to empirically establish the model after conceptualizing it. Discriminant analysis is used as a basic tool to establish the relationship between different events using the data generated from a sample of repeat hotels guests. The results show that surpassing of expectations of the hotel guests affect their perception on pleasant surprises, which in turn affect their consequent happiness. Such happiness along with their perceived excitement and perceived positive feelings create a delighting experience for them. It is hoped that the findings shall encourage other researchers to test this model in different business environments.
Dopamine dysregulation syndrome in non-Parkinson’s disease patients: a systematic review
Authors: Cartoon Jodi , Ramalingam Jothi
Published: April 2019

Objectives:

To explore the presence of dopamine dysregulation syndrome in non-Parkinson’s disease patients receiving dopamine replacement therapy.

Methods:

Electronic searches were conducted of Medline, Embase, PsycINFO and PreMedline to capture articles related to dopamine misuse or factitious disorder combined with the presence of dopamine replacement therapy or a non-Parkinson’s disease population. In total, 430 articles were reviewed and studies that addressed dopamine dysregulation syndrome in non-Parkinson’s disease patients were included.

Results:

Nine case reports were identified.

Conclusions:

The pathophysiology underlying dopamine dysregulation syndrome has been thoroughly explored with numerous mechanisms posited. What remains unclear is whether dopamine dysregulation syndrome is a phenomenon specific to Parkinson’s disease, as indicated in the proposed diagnostic criteria. A more useful predictor of susceptibility to dopamine dysregulation syndrome may be temperamental traits such as novelty seeking and impulsivity, which overlap with predisposing factors for an addiction disorder.
More Time Spent, More Job Search Success?: The Moderating Roles of Metacognitive Activities and Perceived Job Search Progress

Published: April 2019

Taking a self-regulatory perspective, we examined the within-person relationships between time spent in job search and search outcomes (i.e., the number of job interviews/offers received), focusing especially on the moderating roles of metacognitive activities and perceived job search progress. Data collection was conducted with 12 semiweekly surveys among a sample of 132 job seekers from a university in Southern China. Our results showed that time spent in job search does not necessarily lead to more interviews, and metacognitive activities moderated this relationship. Specifically, the positive effect of time spent in job search on the number of job interviews was stronger among job seekers with low levels rather than high levels of metacognitive activities. Nevertheless, after including perceived job search progress, the moderating role of metacognitive activities was stronger among seekers with low rather than high-perceived job search progress. We found that when individuals engaged in low levels of metacognitive activities and perceived low levels of job progress, they relied on time spent in job search to obtain job interviews and offers. The theoretical and practical implications of these findings are discussed.
Translating Deaf Culture: An Ethnodrama
Authors: O’Connell Noel P. , Lynch Teresa
Published: April 2019

This ethnodrama is a script writing project based on qualitative research that explores deaf people’s experience of working as interpreter in Ireland. A collection of interview data was used to develop the ethnodrama by constructing scenes that reveal a series of interactive moments that capture the challenges faced by deaf interpreters. Framed within Sontag’s (1997) conceptualization of “translation,” the authors offer a critique of the term translation and discuss its significance from the perspective of deaf interpreters. Participants were invited to read and comment on aspects of the scenes and contribute to the script writing process. Their statements were integrated into the script to generate meaningful dialogue which appear in the final part of the play. The discussion indicated a positive response to this ethnodrama which was generally successful in producing realistic dramatized scenarios which stimulated reflective discussions in the epilogue.
Evaluating an Intergenerational Model to Explain the Path From Violence Against Mothers to Child Behavior and Academic Outcomes

Published: April 2019

An intergenerational model to explain the long-term effect of partner violence against mothers on child behavior was evaluated 48 months after 278 mothers first sought safe shelter or justice services. Twelve percent reported recent abuse, and six mothers reported severe or extreme danger. Self-efficacy (−.58, p < .05), social support (−28, p < .05), and financial support (−.25) were inversely associated with mental health concerns. Higher maternal mental health concerns (.55, p < .05) and child witnessing abuse (.70, p < .05) were associated with child behavioral problems. Child behavioral problems were inversely associated with child academic functioning (−.22, p < .05). To improve child outcomes, interventions that establish safety for mothers and children and promote maternal mental health are needed.
Elastic bending wave on the edge of a semi-infinite plate reinforced by a strip plate

Published: April 2019

Elastic waves localised near the edge of a semi-infinite plate reinforced by a strip plate are considered within the framework of the 2D classical theory for plate bending. The boundary value problem for the strip plate is subject to asymptotic analysis, assuming that a typical wavelength is much greater than the strip thickness. As a result, effective conditions along the interface corresponding to a plate reinforced by a beam with a narrow rectangular cross-section are established. They support an approximate dispersion relation perturbing that for a homogeneous plate with a free edge. The accuracy of the approximate dispersion relation is tested by comparison with the numerical data obtained from the ‘exact’ matrix relation for a composite plate. The effect of the problem parameters on the localisation rate is studied.
Current status of vascular access in Japan—from Dialysis Access Symposium 2017
Authors: Fukasawa Mizuya
Published: April 2019

At the second Dialysis Access Symposium held in Nagoya, Japan, a proposal was made to investigate the differences in vascular access methods used in different countries. In this article, we describe the management of vascular access in Japan. The Japanese population is rapidly aging, and the proportion of elderly patients on dialysis is also increasing. There were 325,000 dialysis patients in Japan at the end of 2015, of whom 65.1% were aged 65 years or above. The number of patients with diabetic nephropathy or nephrosclerosis as the underlying condition is also increasing, whereas the number with chronic glomerulonephritis is steadily decreasing. The Japanese health insurance system enables patients to undergo medical treatment at almost no out-of-pocket cost. Percutaneous transluminal angioplasty suffers from a severe device lag compared with other countries, but although there are limitations on permitted devices, the use of those that have been authorized is covered by medical insurance. One important point that is unique to Japan is that vascular access is performed and managed by doctors involved in dialysis across a wide range of disciplines, including nephrologists, surgeons, and urologists. This may be one factor contributing to the good survival prognosis of Japanese dialysis patients.

Introduction:

The number of elderly hemodialysis patients continues to grow. The aim of this study was to investigate differences in elderly high flow access patients compared with middle-aged and young patients.

Methods:

We performed a retrospective study to determine the characteristics of elderly patients (aged >60 years) following blood flow suppression procedures. Preoperative and postoperative data from 177 patients who underwent blood flow suppression procedures and 73 patients who underwent procedures for run-off vein ligation and subcutaneous fixation of the superficial artery were compared.

Results:

A high proportion of young (aged 20–40 years) and middle-aged (aged 41–60 years) patients met the criteria for blood flow suppression procedures (flow volume 1500 mL/min, flow volume/cardiac output 35%), whereas a high proportion of elderly patients did not. Moreover, heart strain could evidently be caused even with low flow volume. In elderly patients, a tricuspid regurgitation pressure gradient and right heart strain were observed more frequently.

Conclusion:

Elderly patients who underwent blood flow suppression procedures or subcutaneous fixation of the superficial artery exhibited lower flow volume, and the effects of high flow access in elderly patients depend on the nature of vascular changes. Ultimately, the underlying conditions and hemodynamics of each patient must be determined on an individual basis.
