Dynamic load identification algorithm based on Newmark-β and self-filtering
Authors: Yuchuan Fan , Zhao Chunyu , Hongye Yu , Wen Bangchun
Published: September 2019

In this paper, a dynamic load identification iteration algorithm based on Newmark -β is proposed. Aiming at the problem of excessive iteration error in the process of calculation, a self-filtering algorithm is proposed and added to the load identification algorithm. After adding the self-filtering algorithm, the recognition accuracy of the algorithm has been improved significantly. The recognition result of the proposed method and explicit Newmark- β method is compared by simulations and experiment. The results show that the recognition precision and calculation efficiency of this algorithm are higher, especially in the aspect of calculation efficiency, the proposed method has obvious advantages. Under the same conditions, the proposed method can save a lot of computation time.
Process optimization for rapid manufacturing of complex geometry electrical discharge machining electrode
Authors: Singh Jagtar , Pandey Pulak M
Published: September 2019

Rapid manufacturing techniques permit tools and dies to be fabricated in short duration of time with complex geometry. The major contribution of the present research was to fabricate copper complex geometry electric discharge machining electrode by using amalgamation of three-dimensional printing along with pressureless loose sintering. Response surface methodology was employed to study the sintering parameters’ (sintering temperature, heating rate and soaking time) effect on electric discharge machining electrode important characteristics such as density, shrinkage and electrical conductivity. Analysis of variance was used to investigate the significant contribution of the parameters on the responses. Density and electrical conductivity of fabricated electric discharge machining electrode were revealed to increase with respect to rise in soaking time and sintering temperature. The interaction between the heating rate and sintering temperature for density and electrical conductivity responses signified the less effect of heating rate at high temperatures. Further, multi-objective optimization was used to maximize density and electrical conductivity and to minimize volumetric shrinkage. Different shapes of electric discharge machining electrodes were fabricated at optimized parameters. In addition, the fabricated electrodes were tested on electric discharge machining of D2 steel for 5 mm depth. The dimensional analysis was carried out between the computer aided design (CAD) model, fabricated electric discharge machining electrode and the obtained cavity by electric discharge machining process. The results depicted high efficacy of the process to fabricate complex geometry electric discharge machining electrodes.
Effects of tip-jet on the performance of a ducted fan
Authors: Li Lei , Huang Guoping , Chen Jie
Published: September 2019

Tip-jet technology has potential value for application in vertical take-off and landing or short take-off and landing concept aircraft. The main objective of this current work is to investigate the effects of the tip-jet on the performance of a ducted fan in hover. The overall flow field of the ducted fans with tip-jet was simulated by using the shear-stress transport k-omega turbulence model with a refined high-quality structured grid at various rotational speeds. The comparative analysis of the performances of the ducted fans with different tip-jet locations was carried out. The results indicate that the circulation of the blade with tip-jet is affected by the flow blockage, Coanda effect, and edge-shed vortex. These flow features were formed by the tip-jet. The fan’s thrust could be augmented when the nozzle was a little farther from the blade trailing edge. However, a higher jet flow utility efficiency could be achieved when the nozzle was close to the blade trailing edge.
Young entrepreneurs and non-teleological temporality in Portugal and the UK
Authors: Holdsworth Clare , Mendonça Marina
Published: September 2019

The promotion of young enterprise is central to European Union youth policy, particularly since the financial crisis of 2007/2008. Expectations that young people need to be enterprising and eschew dependency on formal structures of salaried employment are a key narrative in European and national youth policies. These policy initiatives correspond with recent theoretical development of the entrepreneurial self as a managerial version of the governable individual. Endorsements of entrepreneurship implicitly promote a normative expectation that young people’s future orientations need to be innovative, flexible and creative. There is, therefore, an implicit temporality to youth entrepreneurship. This paper’s contribution to scholarship on how young lives are promoted and produced as entrepreneurial selves is to document how young people’s engagement with entrepreneurship fosters orientations to present and future. Conventionally entrepreneurs are assumed to be goal-orientated. In our qualitative study of young entrepreneurs in two European countries (n = 28), we find that this assumption of goal-orientation needs qualification. Young entrepreneurs in our study engage with the idea that being an entrepreneur is about being creative rather than seeking to maximise financial profit. Their focus on creativity, innovation and problem-solving is realised through a non-teleological commitment to what they are doing in the here and now, rather than calibrating their activities in relation to predetermined goals and worrying about the possibility of future failure.
Selective Integration: An Attentional Theory of Choice Biases and Adaptive Choice
Authors: Usher Marius , Tsetsos Konstantinos , Glickman Moshe , Chater Nick
Published: September 2019

Human choice behavior shows a range of puzzling anomalies. Even simple binary choices are modified by accept/reject framing and by the presence of decoy options, and they can exhibit circular (i.e., intransitive) patterns of preferences. Each of these phenomena is incompatible with many standard models of choice but may provide crucial clues concerning the elementary mental processes underpinning our choices. One promising theoretical account proposes that choice-related information is selectively gathered through an attentionally limited window favoring goal-consistent information. We review research showing attentional-mediated choice biases and present a computationally explicit model—selective integration—that accounts for these biases.
Six Challenges for Embodiment Research
Authors: Ostarek Markus , Huettig Falk
Published: September 2019

Twenty years after Barsalou’s seminal perceptual-symbols article, embodied cognition, the notion that cognition involves simulations of sensory, motor, or affective states, has moved from an outlandish proposal to a mainstream position adopted by many researchers in the psychological and cognitive sciences (and neurosciences). Though it has generated productive work in the cognitive sciences as a whole, it has had a particularly strong impact on research into language comprehension. The view of a mental lexicon based on symbolic word representations, which are arbitrarily linked to sensory aspects of their referents, was generally accepted since the cognitive revolution in the 1950s. This has radically changed. Given the current status of embodiment as a main theory of cognition, it is somewhat surprising that a close look at the literature reveals that the debate about the nature of the processes involved in language comprehension is far from settled, and key questions remain unanswered. We present several suggestions for a productive way forward.
Influence of fiber volume fraction and curing temperature on mechanical properties of jute/PLA green composites
Authors: Singh Jai Inder Preet , Singh Sehijpal , Dhawan Vikas
Published: September 2019

Rising environmental concerns and depletion of petrochemical resources have resulted in an increased interest in biodegradable natural fiber-reinforced polymer composites. In this research work, jute fiber has been used as a reinforcement and polylactic acid (PLA) as the matrix material to develop jute/PLA green composites with the help of compression molding technique. The effect of fiber volume fraction ranging from 25% to 50% and curing temperature ranging from 160°C to 180°C on different samples were investigated for mechanical properties and water absorption. Results obtained from various tests indicate that with an increase in the fiber volume fraction, tensile and flexural strength increases till 30% fiber fraction, thereafter decreases with further increase in fiber content. Maximum tensile and flexural strength of jute/PLA composites was obtained with 30% fiber volume fraction at 160°C curing temperature. The trend obtained from mechanical properties is further justified through the study of surface morphology using scanning electron microscopy.
‘We Have to Pay the Price’: German Workers and the US Army, 1945–1989
Authors: Seipp Adam R.
Published: September 2019

This article examines the relationship between German civilian workers and the United States Army in the Federal Republic of Germany during the Cold War. Using archival and published sources, the article offers an entangled history of ‘local national’ employees and their role in maintaining the American presence in Central Europe. Beginning in the late 1960s, German labour unions began to challenge American labour policy. In doing so, they consistently argued for a more forceful assertion of German sovereignty. This labour relationship was therefore important for both the military history of the Cold War and for the development of German democracy.
Awareness of and attitudes towards cervical cancer prevention among migrant Eastern European women in England
Authors: Patel Hersha , Sherman Susan M , Tincello Douglas , Moss Esther L
Published: September 2019

Objectives

It has been hypothesized that, in England, the rise in incidence of cervical cancer and the fall in screening coverage might be attributable in part to the effect of migration of Eastern European born women. We explored the attitudes and behaviours of these women towards cervical cancer prevention strategies.

Methods

A mixed methods study using quantitative surveys and in-depth semi-structured qualitative interviews was conducted between April 2015 and December 2016.

Results

In total, 331 surveys and 46 interviews were completed. Native English women had greater knowledge that a smear test is a screening test for pre-cancerous cervical cells (90% vs. 71% p≤0.01), whereas migrant Eastern European women believed that it was conducted as part of a full gynaecological examination (46% vs. 21% p≤0.01) and that the screen interval was annual (18% vs. 4% p≤0.01). Distrust of the English healthcare system resulted in some Eastern European women returning to their country of birth for screening. Poor awareness of cervical cancer prior to migration and lack of information at registration with a general practitioner in England were associated with failure to participate in screening.

Conclusions

The views and attitudes expressed by the migrant Eastern European women in this study suggest that they are not fully participating in cervical screening in England. Targeted education at the point of contact with healthcare services in England is needed to increase cervical screening participation among these women.
High-performance Work Practices, Affective Commitment of Employees and Organizational Performance: A Multi-level Modelling Using 2-1-2 Mediation Analysis
Authors: Pattnaik Subash Chandra , Sahoo Rashmita
Published: September 2019

The link between high-performance work practices (HPWP) and organizational performance has often been oversimplified, and our understanding as to the mechanisms linking the two is inconclusive, and this study offers some insights by taking HPWP as perceived by employees rather than that reported by managers and proximal employee-level outcomes as intervening explanations. The study examines the influence of employee perceptions towards HPWP use on organizational performance through the mediating variable ‘affective commitment of employee (ACE)’. Data for the study were collected from employees of 30 business units administering pre-existing questionnaires. The model was tested using 2-1-2 mediation analysis (‘bathtub’) as proposed by Croon and van Veldhoven (2007) and it fits well with data. It has important theoretical contributions that perceptions of employees towards HPWP use play an important role and HPWP result in organizational performance through employee-level outcomes such as ACE, the knowledge of which may help practicing managers for getting the best from employees. However, findings of the study are subject to the limitations in that the research suffers in terms of establishing causality, namely, use of cross-sectional data and lack of experimental research design.
Impact of Brand Association on Brand Equity with Specific Focus on Advergames in India
Authors: Jayswal Mitesh , Vora Puja
Published: September 2019

The objective of this article is to study the relationship between brand equity and brand association in the context of advergames in India. Brand association is considered as an independent variable, and its impact on brand equity is investigated. This article includes an initial survey of youngsters of Gujarat state under an experimental research design. The data is analysed using factor analysis, MANOVA and multiple regression. Two factors extracted from the brand association, namely ‘specific attributes’ and ‘intangible attributes’, are found to be significantly impacting brand equity. Out of the two, ‘specific attributes’ explain higher variation compared to ‘intangible attributes’. The findings have practical implications for both academicians and practitioners. Although the findings are restricted to the FMCG sector, they can be somewhat generalized. They can act as a foundation for further research. They can also provide guidelines to the practitioners.
Use of Drug Treatment and Rehabilitation Services in Indonesia: Findings of the 2014 National Narcotic Survey
Authors: Sabarinah
Published: September 2019

This study was conducted to identify factors associated with the utilization of treatment and rehabilitation services by drug abusers. Around 14.7% of drug abusers self-reported as having used treatment and rehabilitation services at any point in their lifetime (90.8% male and 9.2% female). The dependent variable of having “ever used” the services was positively associated with receiving support of family and friends, knowing of an existing treatment and rehabilitation program, having ever been involved in an outreach program activity, experiencing self-treatment, and having a positive perception of the efficacy of the program. Among the 10 cities examined, the findings showed unequal utilization of treatment and rehabilitation services, implying the need to better monitor the use of the services and to develop a community-based treatment that both enables drug abusers to confront barriers to the utilization of treatment and rehabilitation services and also reintegrates drug abusers to the community.
A Theory of Cultural Humility
Authors: Foronda Cynthia
Published: September 2019

Introduction: Leaders are realizing the importance of recognizing diversity and applying cultural humility for successful outcomes. When a difference in perspective is misunderstood or not adequately considered, the resulting conflict interferes with the accomplishment of goals and relationships. With the intent to advance mutual understanding and improve human interactions, a theory to guide nurses and other professions on how to appreciate diversity and apply cultural humility is presented. Method: Guided by Walker and Avant’s strategies, the theory was developed from a synthesis of key concepts and constructs from research and scholarly works. Results: The theory of cultural humility is presented. Discussion: To foster a better understanding of the multiple considerations involved in being culturally humble, this theory provides clarity of the related concepts, influences, and outcomes. This theory may help learners recognize the multiple factors that lead to discordant perspectives and exude flexibility to foster positive outcomes.
Sources of Support and Information During Disease: An Exploratory Study, Comparing Migrant and Nonmigrant Colorectal Cancer Patients in Germany
Authors: Leonhardt Marja , Aschenbrenner Katja , Gröne Jörn , Kreis Martin E. , Lauscher Johannes C.
Published: September 2019

Introduction: The prevalence of cancer diseases among migrants is lower relative to nonmigrants, although this equalizes with increasing duration of residence. There are differences in the health behaviors and disease coping strategies between these two groups. The aim of this analysis is to compare migrant and nonmigrant colorectal cancer (CRC) patients in Germany regarding their sources of support and information during disease. Method: Data from 522 CRC patients, collected through a survey about satisfaction with care, were analyzed by descriptive and multivariate statistics. Results: Migrants and nonmigrants differed in two aspects: Migrants reported to receive the most relevant support during disease more often by nonmedical people, compared with nonmigrants, and they favored videos explaining the therapeutic steps of CRC more than nonmigrants. Discussion: Anticipating which types of support and information sources patients will access during their disease may help guide future diversity management across the field of cancer care.

Published: September 2019

As health care delivery moves toward more complex, team-based systems, the topic of medical teamwork has gained considerable attention and study across disciplines. This systematic review integrates empirical research on teamwork and health care to identify broad trends. We identified and coded 1,818 relevant, English, and peer-reviewed journal articles using a teamwork processes rubric. Several themes emerged. The health care teamwork literature has grown substantially over the past 20 years. Approximately half of the studies were descriptive (rather than interventional or psychometric); the majority relied on quantitative methods. Health care teamwork was also studied in thematically distinct manners. Interpersonal processes were most commonly studied across fields. Of all disciplines, medicine focused most on transition processes, whereas those from team science centered more highly on action processes. There were also finer grained disciplinary differences in content areas of communication and collaboration. Interprofessional journals represent a potential area for interdisciplinary efforts. Implications and future directions are discussed.

Published: September 2019

Objective:

To evaluate dental changes in cleft patients after undergoing orthodontic treatment for at least 2 years.

Hypothesis:

The dental change would decline significantly after 2 years of completing orthodontic treatment.

Design:

This is a retrospective study.

Patient:

Eighteen repaired cleft lip and palate patients from the Faculty of Dentistry, KhonKaen University, Thailand, participated in this study.

Mean Outcome Measures:

A dental model with before treatment (T0), completed treatment (T1), and retention period (T2) data was analyzed using the peer assessment rating (PAR) index.

Result:

The results showed that the PAR score improved enormously after treatment; from T0 to T1, it was 34.00 ± 10.01 to 4.67 ± 2.47, and there was a reversion in the retention period. There was statistical significance between T0, T1, and T2, with P values <.001, .005, and <.001 when comparing T0 with T1, T1 with T2, and T0 with T2, respectively.

Conclusion:

Occlusion in cleft lip and palate patients changed from the time of completing treatment to the final results after the retention period. To sustain satisfactory results, orthodontists should plan carefully for the retention period before performing the treatment.
Examining the Psychosocial Needs of Adolescents With Craniofacial Conditions: A Mixed-Methods Approach
Authors: Riklin Eric , Calandrillo Dominique , Blitz Aileen , Zuckerberg Dina , Annunziato Rachel A.
Published: September 2019

Objective:

To determine, for intervention development, the psychosocial needs of adolescents diagnosed with a craniofacial condition who attended focus group sessions.

Design:

A mixed-methods design combining qualitative focus groups with quantitative measures.

Setting:

An outpatient clinic at a major medical center in Manhattan, New York.

Participants:

Fourteen adolescents, aged 14 to 18, with craniofacial conditions.

Main Measures:

Participants completed measures assessing a range of psychological constructs. Average scores were compared to clinical cutoff scores and normative data for adolescents. The 2 focus groups were coded using an inductive approach to assess pertinent themes. Additionally, the acceptability and feasibility of a proposed intervention was measured.

Results:

Adolescents with craniofacial conditions were within normal ranges for quality of life, self-esteem, and body image and they reported higher resiliency. They were above cutoff scores for perceived stress and post-traumatic stress disorder symptoms and below cutoff scores for mindfulness. When compared to normative samples, they displayed higher perceived social support, but lower coping. Based on qualitative analyses, 6 themes emerged: stress, bullying, coping, resiliency, mindfulness, and social support. Both qualitative and quantitative analyses revealed most participants were supportive of a future intervention for this population.

Conclusions:

The present study identified several factors associated with psychological well-being of adolescents with craniofacial diagnoses and demonstrates the importance of creating interventions to target specific psychosocial needs. Findings from this study may guide researchers in developing and refining a specific program for this population and provide information to help those with craniofacial conditions who are experiencing psychosocial challenges.
Mammary Paget’s Disease of the Male Breast: A Rare Case With an Unusual Immunohistochemical Profile
Authors: Moore Samantha A. , Notgrass Hollis M. , Vandergriff Travis W. , Sahoo Sunati
Published: September 2019

Mammary Paget’s disease is rare and comprises about 0.62% of all breast cancer cases, only 1.65% of which occur in male patients. This case report involves a 76-year-old man who presented to his primary care physician with an itching, scaly, unilateral lesion involving the nipple skin. He underwent wide local excision of the lesion for a diagnosis of Bowen’s disease (squamous cell carcinoma in situ). Histologic examination of the specimen revealed mammary Paget’s disease with ductal carcinoma in situ in the underlying breast tissue. A panel of immunohistochemical stains revealed the Paget cells to be positive for cytokeratin 7, MUC1, GATA3, and androgen receptor and negative for cytokeratins 5/6, p63, SOX10, and MART-1/Melan-A. Paget cells were also negative for estrogen receptor and progesterone receptor, and positive for HER2/neu. However, the underlying ductal carcinoma in situ was positive for both estrogen receptor and progesterone receptor and negative for HER2/neu. This discordance, supported by the current literature, suggests an alternative etiology for Paget’s disease in certain cases that cannot be explained by the well-established epidermotropic and transformative theories of Paget’s disease evolution.
Projected Retained Ability Score (PRAS): A New Methodology for Quantifying Absolute Change in Norm-Based Psychological Test Scores Over Time
Authors: Kronenberger William G. , Harrington Magdalena , Yee Karen S.
Published: September 2019

A limitation of norm-based ability test scores is that they can only be used to evaluate relative change (compared with change in the norm sample), as opposed to absolute (raw) change in performance from Time 1 to Time 2. To address this limitation, a novel method (Projected Retained Ability Score [PRAS]) was developed to characterize absolute change in norm-based ability test scores. The PRAS method was applied to Differential Ability Scales®–Second Edition (DAS-II) General Conceptual Ability (GCA) scores in three cases of children with the neurodegenerative condition mucopolysaccharidosis type II (MPS II) who were assessed at two visits, 16 to 23 months apart. Although all three cases showed declines in norm-based GCA scores, the PRAS method revealed differences in absolute change in performance. The PRAS method allows for differentiation of slower-than-average improvement or stabilization versus deterioration of cognitive ability when norm-based scores decline from Time 1 to Time 2.
Comparing the Boston Naming Test With the Neuropsychological Assessment Battery–Naming Subtest in a Neurodegenerative Disease Clinic Population
Authors: Durant January , Berg Jody-Lynn , Banks Sarah J. , Kaylegian Jaeson , Miller Justin B.
Published: September 2019

The Boston Naming Test–Second edition (BNT-2) and the Neuropsychological Assessment Battery–Naming (NAB-N) subtest are two commonly used confrontation naming tests used to evaluate word-finding ability in individuals suspected of neurodegenerative disease. The BNT-2 and NAB-N are designed to measure the same construct; however, observations in practice suggest these two tests provide divergent estimates of naming ability. This study sought to systematically investigate the level of agreement between performance on the BNT-2 and NAB-N. Records from 105 consecutive referrals seen for neuropsychological evaluation as part of routine care in an outpatient memory disorders clinic were reviewed. Discrepancy scores, concordance correlation coefficients, and root mean squared differences were calculated between demographically adjusted T-scores on the BNT-2 and NAB-N. Results indicated that estimates of word finding ability generated by the BNT-2 and NAB-N have a strong linear relationship but systematically generate scores that are inconsistent. Despite similar task demands, the BNT-2 and NAB-N provide different information about naming ability and further research is needed to understand these differences and inform clinicians on interpreting the naming estimates provided by each test.
Insight Into Individual Differences in Emotion Dynamics With Clustering
Authors: Ernst Anja F. , Timmerman Marieke E. , Jeronimus Bertus F. , Albers Casper J.
Published: September 2019

Studying emotion dynamics through time series models is becoming increasingly popular in the social sciences. Across individuals, dynamics can be rather heterogeneous. To enable comparisons and generalizations of dynamics across groups of individuals, one needs sophisticated tools that express the essential similarities and differences. A way to proceed is to identify subgroups of people who are characterized by qualitatively similar emotion dynamics through dynamic clustering. So far, these methods assume equal generating processes for individuals per cluster. To avoid this overly restrictive assumption, we outline a probabilistic clustering approach based on a mixture model that clusters on individuals’ vector autoregressive coefficients. We evaluate the performance of the method and compare it with a nonprobabilistic method in a simulation study. The usefulness of the methods is illustrated using 366 ecological momentary assessment time series with external measures of depression and anxiety.
The Development and Validation of the Compassion Scale
Authors: Pommier Elizabeth , Neff Kristin D. , Tóth-Király István
Published: September 2019

This article presents a measure of compassion for others called the Compassion Scale (CS), which is based on Neff’s theoretical model of self-compassion. Compassion was operationalized as experiencing kindness, a sense of common humanity, mindfulness, and lessened indifference toward the suffering of others. Study 1 ( n = 465) describes the development of potential scale items and the final 16 CS items chosen based on results from analyses using bifactor exploratory structural equation modeling. Study 2 ( n = 510) cross-validates the CS in a second student sample. Study 3 ( n = 80) establishes test–retest reliability. Study 4 ( n = 1,394) replicates results with a community sample, while Study 5 ( n = 172) replicates results with a sample of meditators. Study 6 ( n = 913) examines the finalized version of the CS in a community sample. Evidence regarding reliability, discriminant, convergent, construct, and known-groups validity for the CS is provided.
Child Maltreatment and Aggressive Behaviors in Early Adolescence: Evidence of Moderation by Parent/Child Relationship Quality
Authors: Fagan Abigail A.
Published: September 2019

The cycle of violence suggests that maltreatment increases children’s aggression, but research shows that many children are resilient to the harms caused by maltreatment. This study examines whether or not parent/child relationship quality accounts for variation in the impact of maltreatment on aggression and hypothesizes that the effect will be weaker for children who have better relationships with their caregivers. Race differences in these effects are also examined. Based on prospective data from a high-risk sample of 620 (207 White and 413 Black) families in the Longitudinal Studies of Child Abuse and Neglect, ordinary least squares regression analyses indicated that youth with at least one official allegation of maltreatment before age 10 had significantly more frequent aggressive behaviors at age 12. The direct effect of maltreatment on aggression did not vary for Black and White youth. However, a significant three-way interaction indicated that parent/child relationship quality buffered the relationship between maltreatment and aggressive behaviors for White but not Black children. Although additional research is required to identify factors that ameliorate the impact of maltreatment for Black youth, the findings support the need for interventions to help children cope with maltreatment and to strengthen parent/child relationships.
STABLE-2007 Demonstrates Predictive and Incremental Validity in Assessing Risk-Relevant Propensities for Sexual Offending: A Meta-Analysis
Authors: Brankley Andrew E. , Babchishin Kelly M. , Hanson R. Karl
Published: September 2019

STABLE-2007 is a measure of risk-relevant propensities for adult males convicted of a sexual offense. This meta-analysis evaluated the ability of STABLE-2007 and its items to discriminate between recidivists and nonrecidivists, and the extent to which STABLE-2007 improves prediction over and above Static-99R. Based on 21 studies (12 unique samples, N = 6,955), we found that STABLE-2007 was significantly and incrementally related to sexual recidivism, violent (nonsexual) recidivism, violent (including sexual) recidivism, and any crime. Scores on STABLE-2007 items and the three STABLE-2000 attitude items also discriminated between individuals who sexually reoffended and those who did not sexually reoffend. These findings support the use of STABLE-2007 in applied risk assessment practice and the interpretation of STABLE-2007 items as indicators of treatment and supervision targets.

Published: September 2019

In this article, we study the I/O performance of the Santos Dumont supercomputer, since the gap between processing and data access speeds causes many applications to spend a large portion of their execution on I/O operations. For a large-scale expensive supercomputer, it is essential to ensure applications achieve the best I/O performance to promote efficient usage. We monitor a week of the machine’s activity and present a detailed study on the obtained metrics, aiming at providing an understanding of its workload. From experiences with one numerical simulation, we identified large I/O performance differences between the MPI implementations available to users. We investigated the phenomenon and narrowed it down to collective I/O operations with small request sizes. For these, we concluded that the customized MPI implementation by the machine’s vendor (used by more than 20% of the jobs) presents the worst performance. By investigating the issue, we provide information to help improve future MPI-IO collective write implementations and practical guidelines to help users and steer future system upgrades. Finally, we discuss the challenge of describing applications I/O behavior without depending on information from users. That allows for identifying the application’s I/O bottlenecks and proposing ways of improving its I/O performance. We propose a methodology to do so, and use GROMACS, the application with the largest number of jobs in 2017, as a case study.
Peter Pan Syndrome “Men Who Don’t Grow”: Developing a Scale
Authors: Kalkan Melek , Batık Meryem Vural , Kaya Leyla , Turan Merve
Published: September 2019

Peter Pan Syndrome is a concept that used to characterize the “never-growing” men who have reached an adult age, but cannot face their adult sensations and responsibilities. Individuals with Peter Pan Syndrome have difficulties in social and professional relationships because of their irresponsible behaviors and narcissistic properties. The purpose of this study is to develop a scale in order to measure the level of Peter Pen Syndrome in male individuals. In accordance with this purpose, the draft form was sent to experts to get their feedback, and some statements have been revised in accordance with the feedback. The Peter Pan Syndrome Scale is a twenty-two-item self-report measurement, and each item is evaluated on five-point Likert Type scale. Construct validity of the scale was determined by exploratory factor analysis (EFA) and a three-factor model was created, namely, “Escape from Responsibility”, “Power Perception,” and “Never Growing Child”. EFA results shows that these three factors were describing 47.05% of the variance. Results of EFA were verified by confirmatory factor analysis (CFA). The internal consistency coefficient and the confidence coefficient of the split-half were used to determine the reliability of the scale. The Cronbach’s alpha value was found to be 0.88 for the total scale.
An Empirical Examination of Evaluation’s Presence in the Undergraduate Curriculum in the United States
Authors: LaVelle John M. , Sabarre Nina , Umans Haley
Published: September 2019

Evaluator education programs have developed to help support the growth of professional evaluators and improve evaluation practice. Empirical research has described where and how evaluation is taught at the graduate level of education, but little is known about the undergraduate level. This study empirically explores how, if at all, evaluation is taught at the undergraduate level by systematically analyzing the publicly available curricula of the top 40 public and top 40 private universities in the United States. Findings demonstrate that 470 evaluation-specific and associated courses were offered across public colleges and universities (335 courses offered) and private colleges (135 courses offered). However, among these 470 courses, the extent to which evaluation is taught varies from a specific method of systematic inquiry to a tool used for assessment or judgment, or minor topic within a broader subject. Implications for the field are discussed.
Measuring Academic Output During the Good Behavior Game: A Single Case Design Study
Authors: Fallon Lindsay M. , Marcotte Amanda M. , Ferron John M.
Published: September 2019

The impact of the Good Behavior Game (GBG) on students’ classroom behavior has been studied for 50 years. What is less established is the impact of the GBG on students’ academic progress. With emerging research in curriculum-based measurement for written expression (WE-CBM), it may be possible to observe changes in students’ writing output while playing the GBG versus when the game is not played. The purpose of the current study was to systematically introduce the GBG during writing practice time in a Grade 1 and Grade 2 classroom, and observe any changes to all students’ academic engagement, disruptive behavior, as well as target students’ writing output using WE-CBM. Results indicated large increases in all students’ academic engagement and decreases in disruptive behavior when the GBG was played. For writing output, target students demonstrated modest improvement in the amount of words written and accuracy of writing when the game was played, especially students identified as having emerging writing skills. Future studies might continue to empirically explore the connection between behavioral intervention and academic output by replicating study procedures in different contexts and/or with alternative WE-CBM indices.
Chronic myeloid leukaemia accelerates proliferative retinopathy in patients with co-existent diabetes: A risk factor not to be ignored
Authors: Chawla Rohan , Kumar Suneel , Kumawat Devesh , Azad Shorya Vardhan , Temkar Shreyas , Jain Shreyans
Published: September 2019

Objective:

To describe the retinal imaging characteristics, retinopathy management strategies and visual outcomes in cases of diabetes with chronic myeloid leukaemia.

Design:

Retrospective observational study.

Participants:

Patients with diabetes and chronic myeloid leukaemia managed at our tertiary eye care centre from January 2015 to December 2017.

Methods:

Detailed ophthalmic and systemic evaluation, treatment and follow-up records were reviewed. The main measures studied were visual acuity, intra-ocular pressure, retinopathy severity, and surgical indications and techniques.

Results:

Of the six patients studied, three had diabetes and chronic myeloid leukaemia at presentation, while in three cases chronic myeloid leukaemia was diagnosed following evaluation for proliferative retinopathy. The visual acuity ranged from 20/20 to perception of light. All eyes had marked proliferative retinopathy out of proportion to the exudation. None of the eyes had significant macular oedema. Pan-retinal photocoagulation (10/12, 83.33%), intravitreal anti-vascular endothelial growth factor injection (8/12, 66.67%), vitrectomy (2/12, 16.67%), cataract surgery (2/12, 16.67%) and trabeculectomy followed by cryoablation (2/12, 16.67%) was performed for management of the ocular disease as indicated. Median follow-up was 16.5 months (range: 6–24 months). Final visual acuity ranged from PL to 20/20 with acuity ⩾ 20/100 in eight eyes. Four eyes had advanced optic neuropathy from neovascular glaucoma.

Conclusion:

Accelerated proliferative retinopathy can be seen in cases of diabetes with chronic myeloid leukaemia at the very initial ophthalmic evaluation. Thus, there is a need to alter screening guidelines for retinopathy in cases of diabetes with chronic myeloid leukaemia. Early detection and aggressive management may help preserve visual acuity in such cases.

Objective:

To understand the swimming experience from the perspective of children with autism spectrum disorder (ASD) and their families.

Methods:

We interviewed 12 diverse families using a semi-structured interview with follow-up probing questions related to their swimming experiences. Interviews were transcribed verbatim and coded by researchers.

Results:

Themes included family water activities, safety, characteristics of ASD, instructional methods, swim skills, swimming preferences, barriers/challenges, and benefits of swimming. Findings indicate positive experiences and skill acquisition were prevalent when instructional methods matched a child’s unique needs. Parents revealed they were more confident in safety as their children’s swimming competence improved. Individualized instructional methods and unique characteristics of ASD may influence perceived safety.
Special Places, Sacred Spaces: Two Traditional Buddhist Temples in Nihonmachi Los Angeles
Authors: Gordon Robert E.
Published: September 2019

This article explores two significant Buddhist temples in Los Angeles’s Little Tokyo, the Nishi Hongwanji, and the Higashi Honganji Buddhist Churches. The study’s methodology is inspired by Yi-Fu Tuan’s humanistic geography, whose work explores the relationship between environment and human subjective experience. As the majority of 20th-century Japanese immigrants were Buddhists, a closer look at the temples helps explicate the dynamic between Buddhist belief and its architectural expression. This article takes the concept of a binary as its framework. It explores Little Tokyo in terms of the sacred and profane, the inner and outer, and the vertical and the horizontal vis-à-vis two Buddhist temples. The argument here is that these dualities resolve into one holistic experience with respect to the formation of memory, history, and religious faith.
Gendered trends in young people’s participation in active lifestyles: The need for a gender-neutral narrative
Authors: Metcalfe Sarah Nicola , Lindsey Iain
Published: September 2019

Gendered differences in participation in active lifestyles (encompassing sport, physical activity, and physical education) are well established, with young men typically participating in more activities than young women. This paper uses a theoretical approach inspired by Bourdieu’s notions of habitus, field and capital to explore the ‘how’ and ‘why’ of these differences. Drawing on mixed-methods data obtained from questionnaires ( n = 332) and semi-structured interviews with 33 young men and 37 young women aged 15–16, we present two gendered trends which explain gendered differences in active lifestyle participation. Firstly, in this research, young men participated in more activities than young women, viewing their participation as integral to their identity, their sense of self. Young women, in contrast, viewed sport as an ‘optional’ extra, something they could do, if they wished. Secondly, in relation to the differences in the type of activities participated in, young men were more likely to participate in traditional team sports, whereas young women chose to engage in gym/fitness activities to promote appearance and feminine attractiveness. We argue that the gendered norms which dictate ‘appropriate’ gendered active identities are damaging to both young men and women who may wish to deviate from these norms. Social capital is allocated to gendered bodies in accordance with these norms, influencing how young people are viewed in their social hierarchies. A gender-neutral narrative which destabilises gendered sporting norms whilst simultaneously celebrating diversity is needed to promote a safe and inclusive environment where all young men and women can engage in sufficient physical activity.
Spirituality and subjective well-being of Ghanaian parents of children with special needs: The mediating role of resilience
Authors: Dey Nutifafa Eugene Yaw , Amponsah Benjamin , Wiafe-Akenteng Charles Brenya
Published: September 2019

The study explored the mediating role of resilience in the relationship between spirituality and subjective well-being of 107 Ghanaian biological parents raising children with special needs. Results from mediational analyses revealed that spirituality indirectly influenced life satisfaction, positive affect and negative affect through resilience. Specifically, greater levels of spirituality predicted greater resilience, which successively led to greater life satisfaction, greater positive affect and reduced negative affect. These findings emphasize the necessity of targeting parents’ well-being through resilience to help them deal with the burden of providing care for their children with special needs.
Four decades of ELT development in Hong Kong: Impact of global theories on the changing curricula and textbooks
Authors: Chan Jim Yee Him
Published: September 2019

The past 40 years have witnessed significant developments in ELT research, reflecting the changes in learners’ language needs and the extensive development of various language learning/teaching methods in different times and places. The aim of this study is to provide a systematic and comprehensive account of changing ELT methods (oral-structural approach, communicative language teaching and task-based language teaching) in Hong Kong’s secondary education between 1975 and the present. By adopting Richards and Rodgers’s (2014) framework (approach, design and procedure), it examined how ELT theories have been transformed into local curricula (1975, 1983, 1999 and 2002/07) and commercial textbooks (Longman, Oxford University Press) via detailed content analysis. The findings suggest that research into ELT methods in Hong Kong over the past decades has generally directed the designs of the language curricula. Changes in the textbooks, however, have been relatively limited, although considerable attempts have been made to align textbook design with ELT trends. By considering various constraints in the theory-to-practice process, this study offers suggestions for future research and language teaching, particularly regarding the recent debate over the choice between the ‘weak’ and ‘strong’ versions of task-based language teaching in EFL contexts, and the post-methods perspective in language teaching.
Chaotic enhanced colliding bodies optimization algorithm for structural reliability analysis
Authors: Cheng Jiaming , Zhao Wei
Published: September 2019

It is of extreme importance to assess the failure probability and safety level of structural system in structural design. Nowadays, many researchers presented several approaches for structural reliability analysis, such as the first-order reliability method, Monte Carlo simulation, and the meta-heuristic algorithm. The meta-heuristic algorithm is not only efficient to solve global optimization problems but also shown to be an effective tool for structural reliability analysis. A recent meta-heuristic optimization approach, enhanced colliding bodies optimization, has emerged as a relatively simple implementation with a fast convergence speed. Chaos theory is characterized by its ergodicity, pseudo-randomness, and irregularity. This article thus presents a novel approach introducing chaotic maps into the enhanced colliding bodies optimization algorithm to promote the performance of convergence, named as chaotic enhanced colliding bodies optimization algorithm. The proposed algorithm uses chaotic maps to change the generation pattern of particles and improve convergence characteristics. A procedure based on the effective use of the represented chaotic enhanced colliding bodies optimization is then applied in structural reliability analysis. A variety of numerical and structural problems are tested in this article to demonstrate that the given method actually improves the performance of enhanced colliding bodies optimization in convergence as well as the accuracy for reliability analysis compared with the other methods existing in the literature.
