Study on relationships among sports spectator motivations, satisfaction and behavioral intention: empirical evidence from Chinese marathon
Authors: Duan Yanling , Liu Bing , He Yan 
Published: July 2019

PurposeThe paper aims to examine the relationships among marathon spectator motivation, satisfaction and behavioral intention in China.Design/methodology/approachDate were collected from three Chinese marathon races. The paper presents the conceptual model of the study and adopted a mixed method to identify the motivations of marathon spectators; structural equation modeling (SEM) was used to test the measurement and substantive models; regression analysis was used to detect the specific effects of the various spectator motivations on spectator satisfaction and behavioral intention.FindingsThe paper provides empirical evidences about how marathon spectator motivation affects the behavioral intention. The research results from a path analysis of the spectator motivation–satisfaction–behavioral intention model show that: spectator motivation has significant positive effects on behavioral intention, the indirect path dominates the total effect of motivation on behavioral intention via satisfaction as a mediating variable; satisfaction is positively associated with behavioral intention, and it plays mediate role between spectator motivation and behavioral intention. The result of regression analysis indicates that various spectator motivations have different influences on the satisfaction and behavioral intention, motives of excitement and diversion have significant effect on satisfaction and behavioral intention, but socialization motive is not significantly associated with the satisfaction and behavioral intention.Originality/valueThis paper first fulfills an identified need to explore mass sports event spectator motivations and its influential mechanism on behavioral intention among Chinese marathon races by survey. It contributes greatly to the literature of mass sports spectator motivation and consumption theory, provides important managerial implications for Chinese sports organizations as to how to improve spectator orientation degree.
Structural relationship between market demand and member commitment associated with the marketing of martial arts programs
Authors: Kim Minkil , Zhang James 
Published: July 2019

Purpose
This study was conducted to ensure that the selected antecedent concepts, including market demand and psychological factors, were fully focused and studied in detail and depth. The purpose of this paper is to develop and test a theoretical framework that specifies direct and indirect relationships among market demand, perceived benefits, perceived constraint, perceived value, consumer satisfaction and member commitment in martial arts programs.

Design/methodology/approach
Research participants (n=595) were martial arts school participants, who resided in the USA. A confirmatory factor analysis was conducted to evaluate the measurement model and the proposed model was tested by conducting structural equation modeling analyses.

Findings
Findings of this study indicated that perceived benefits and perceived constraints partially mediated the relationship between the market demand factors and perceived value, which in turn influenced member satisfaction and commitment. Economic Condition Consideration was found to be the most critical predictor of market demand.

Originality/value
Generating what-to-do and how-to-do implications that were specific to martial arts school and marketing practices were the priority of the investigators of this study. Administrators of martial arts programs may consider adopting the resultant theoretical framework as a general guide in their marketing efforts to recruit and retain program participants.

Authors: Sahani Ashok Kumar , Samanta Amiya K. , Singharoy Dilip K. 
Published: July 2019

Purpose
Present study focuses on scope of developing sustainable heat resistant concrete by adding steel fibre (Sf) and polypropylene fibre (PPf) along with partially replacement of ordinary portland cement (OPC) and natural fine aggregate with fly ash (FA) and granular blast furnace slag (GBFS). Replacement percentages of FA and GBFS were 40% and 50%, whereas Sf and PPf for fibre-added mixes were 1% by volume of concrete and 0.25% by weight of cement, respectively.

Design/methodology/approach
An experimental work had been carried out to make comparison between control mix (CM), fibre-added sustainable mix (SCMF) and fibre-added control mix (CMF) with reference to weight loss, mechanical strength (compressive, split and flexure) after exposed to room temperature (27°C) to 1000°C at the interval of 200°C for 4 h of heat curing followed by furnace cooling and then natural cooling. Furthermore, microstructural analysis was executed at 27°C, 400°C and 800°C, respectively.

Findings
Colour change and hair line cracks were started to appear at 600°C. Fibre-added control mix and sustainable mix did not exhibit any significant cracks as compared to control mix even at 1000°C. Major losses were occurred at temperature higher than 600°C, loss in compressive strength was about 70% in control mix, while 60% in fibre-added mixes. SCMF exhibited the highest retention of strength with respect to all cases of mechanical strength.

Research limitations/implications
Present study is based on the slow heating condition followed by longer duration of heat curing at target temperature.

Practical implications
Present work can be helpful for the design engineer for assessing the fire deterioration of concrete structure existing near the fire establishment such as furnace and ovens. Building fire (high temperature for short duration) might be the further scope of work.

Originality/value
Concept of incorporating pozzolanic binder and calcareous fine aggregate was adopted to take the advantage pozzolanacity and fire resistivity. To the best of author’s knowledge, there is a scope for fill the research gap in this area.
Examining the relationships among cognitive diversity, knowledge sharing and team climate in team innovation
Authors: Rahmi Devi Yulia , Indarti Nurul 
Published: July 2019

PurposeThis study aims to examine the role of knowledge sharing as a mediating variable on the effect of cognitive diversity on team innovation. Additionally, the study also tests the role of a moderating variable team climate on the relationship between cognitive diversity and knowledge sharing.Design/methodology/approachThe study used an explanatory approach to test the hypothesis. A survey with structured questionnaires was distributed to 39 creative teams between radio and television broadcasting institutions in the Province of Yogyakarta, Indonesia.FindingsThe current study shows cognitive diversity has a significant association with knowledge sharing, and knowledge sharing positively associated with team innovation. The findings of this study indicate that team climate moderates the relationship between cognitive diversity and knowledge sharing. Additionally, knowledge sharing is found not to be a significant mediation on the relationship between cognitive diversity and team innovation.Research limitations/implicationsThe study promises to examine how diverse teams work particularly in the context of creative teams in radio and television broadcasting institutions. However, this study only focuses on relationships; it does not examine the processes underlying those relationships. This study implies for future research agenda focusing on the mechanism affecting the relationships. Additionally, examining the relationship model in the context of a less-creative team such as banking industry could also a call for future research.Practical implicationsThe results of the study contribute to managerial implications which suggest that to enhance team innovation, a team leader must design a comfortable working climate that stimulates productive knowledge sharing.Originality/valueThe study provides a comprehensive understanding of knowledge sharing and team climate on the relationship between cognitive diversity and team innovation, which are missing in previous empirical studies. Then, the study is relevant because of inconclusive findings from past studies examining the relationship between cognitive diversity and team innovation.
Research Note: Frequency domain orthogonal projection filtration of surface microseismic monitoring data
Authors: Azarov Anton V. , Serdyukov Aleksander S. , Gapeev Denis N. 
Published: July 2019

ABSTRACTWe address the problem of increasing the signal‐to‐noise ratio during surface microseismic monitoring data processing. Interference from different seismic waves causes misleading results of microseismic event locations. Ground‐roll suppression is particularly necessary. The standard noise suppression techniques assume regular and dense acquisition geometries. Many pre‐processing noise suppression algorithms are designed for special types of noise or interference. To overcome these problems, we propose a novel general‐purpose filtration method. The goal of this method is to amplify only the seismic waves that are excited in the selected target area and suppress all other signals. We construct a linear projector onto a frequency domain data subspace, which corresponds to the seismic emission of the target area. The novel filtration method can be considered an extension of the standard frequency–wavenumber flat wave filtration method for non‐flat waves and arbitrary irregular receiver‐position geometries. To reduce the effect of the uncertainty of the velocity model, we suggest using additional active shot data (typically the perforation shots), which provide static travel time corrections for the target area. The promising prospects of the proposed method are confirmed by synthetic and semi‐synthetic data processing.

SummaryA specific white spotting phenotype, termed finching or line‐backed spotting, is known for all Pinzgauer cattle and occurs occasionally in Tux‐Zillertaler cattle, two Austrian breeds. The so‐called Pinzgauer spotting is inherited as an autosomal incompletely dominant trait. A genome‐wide association study using 27 white spotted and 16 solid‐coloured Tux‐Zillertaler cattle, based on 777k SNP data, revealed a strong signal on chromosome 6 at the KIT locus. Haplotype analyses defined a critical interval of 122 kb downstream of the KIT coding region. Whole‐genome sequencing of a Pinzgauer cattle and comparison to 338 control genomes revealed a complex structural variant consisting of a 9.4‐kb deletion and an inversely inserted duplication of 1.5 kb fused to a 310‐kb duplicated segment from chromosome 4. A diagnostic PCR was developed for straightforward genotyping of carriers for this structural variant (KITPINZ) and confirmed that the variant allele was present in all Pinzgauer and most of the white spotted Tux‐Zillertaler cattle. In addition, we detected the variant in all Slovenian Cika, British Gloucester and Spanish Berrenda en negro cattle with similar spotting patterns. Interestingly, the KITPINZ variant occurs in some white spotted animals of the Swiss breeds Evolèner and Eringer. The introgression of the KITPINZ variant confirms admixture and the reported historical relationship of these short‐headed breeds with Austrian Tux‐Zillertaler and suggests a mutation event, occurring before breed formation.

Published: July 2019

AbstractAimThis study assessed the impact of illness perceptions, emotional responses to the disease and its management, and patient characteristics on the adherence to optimal insulin pump management in adolescents with type 1 diabetes mellitus.MethodsFrom May to December 2013 and May 2015 to September 2016, we investigated 90 adolescents (50% boys), 12‐18 years with type 1 diabetes. We analysed the association of optimal adherence to insulin pump therapy to age, gender, diabetes duration, results of questionnaires relating to fear and problems of self‐testing, illness perceptions, emotional distress and family conflicts. Optimal adherence was defined as bolusing insulin on average ≥2.5/3 main meals/d.ResultsAdolescents with suboptimal adherence were on average 1.8 years older (95% Confidence Interval 1.09‐2.50 years, P < .001) than those with optimal adherence. After adjustment for age, no other patient or parent factors were related to optimal adherence.ConclusionAdherence to insulin pump self‐management in adolescents with type 1 diabetes declined with increasing age, illustrating the challenges of transition of self‐management from parents to the adolescent patient themselves.

Published: July 2019

AbstractThis study aimed to characterize the relationship between the growth of rumen papillae in calves and the mRNA expression of insulin‐like growth factor‐binding proteins (IGFBPs) in the rumen papillae. The length of rumen papillae, the mRNA expression of IGFBPs in rumen papillae by quantitative real‐time PCR, and the presence of insulin‐like growth factors I and II (IGF‐I and II) by immunohistochemistry (IHC) were analyzed in nine Holstein calves divided into three groups: suckling (2 weeks, n = 3), milk‐continued (8 weeks, n = 3), and weaned (8 weeks, n = 3). The length of rumen papillae was greater (p < 0.01) in weaned calves than in suckling and milk‐continued calves, whereas the expressions of IGFBP2, IGFBP3, and IGFBP6 genes were lower (p < 0.05) in the rumen papillae of weaned calves than in milk‐continued calves. Thus, rumen papillae length and IGFBP2, 3, and 6 expressions were negatively correlated. The IHC analysis showed that IGF‐I and IGF‐II were present in the rumen epithelium of calves. These results suggested that the growth of rumen papillae after weaning is associated with the induction of IGFs by the low levels of IGFBP2, IGFBP3, and IGFBP6.

Published: July 2019

AbstractThis study presents an advanced predictive learning analytics system, OU Analyse (OUA), and evidence from its evaluation with online teachers at a distance learning university. OUA is a predictive system that uses machine learning methods for the early identification of students at risk of not submitting (or failing) their next assignment. Teachers have access, via interactive dashboards, to weekly predictions of risk of failing for each of their students. In this study, we examined how the degree of OUA usage by 559 teachers, of which 189 were given access to OUA, related to student learning outcomes of more than 14 000 students in 15 undergraduate courses. Teachers who made “average” use of OUA, that is accessed OUA throughout the life cycle of a course presentation, and in particular between 10% and 40% of the weeks a course was running, and intervened with students flagged as at risk were found to benefit their students the most; after controlling for differences in academic performance, these students were found to have significantly better performance than their peers in the previous year's course presentation during which the same teachers made no use of predictive learning analytics. Predictive learning analytics is an innovative student's support approach in online pedagogy that, as shown in this study, can empower online teachers in effectively monitoring and intervening with their students, over and above other approaches, and result in improved learning outcomes.
Practitioner NotesWhat is already known about this topic

Pedagogical and personal support to students is a significant responsibility of online teachers.
Student's support is a challenging activity due to the lack of face‐to‐face interactions.
Predictive learning analytics (PLA) can identify students at risk of failing their studies.
What this paper adds

One of the few large‐scale studies is available for examining the impact of analytics on student's performance.
Teachers' usage of PLA was significantly related to better learning outcomes.
Online teachers had students with better learning outcomes when accessing PLA data rather than when they had no access.
Implications for practice and/or policy

PLA can empower online teachers and complement the teaching practice.
PLA can help in the identification and proactive intervention of students at risk of failing their studies.
Actions should be taken to motivate and engage online teachers with PLA.
Uberizing the Legal Profession? Lawyer Autonomy and Status in the Digital Legal Market
Authors: Yao Yao 
Published: July 2019

AbstractThe online gig economy has disrupted many occupations in the past decade, but only more recently has it had an impact on professional fields. The recency of this trend indicates a need for understanding the impact of the online gig economy on professional workers. Using interview data from lawyers who work on one of China's most successful online legal service platforms, this study finds that supplementary income and flexibility are the two major motives for lawyers to work online. Nevertheless, when working online, lawyers face lower intra‐professional status and lower professional autonomy. Despite its growth, the digital legal market is imposing a minimal threat to the traditional legal market due to the lack of interference in labour supply and demand between these two markets.
Objective vs self‐report assessment of height, weight and body mass index: Relationships with adiposity, aerobic fitness and physical activity
Authors: Wilson Oliver W. A. , Bopp Christopher M. , Papalia Zack , Bopp Melissa 
Published: July 2019

SummaryResearchers, policymakers and clinicians commonly use height and weight to determine body mass index (BMI) and classify weight status. Self‐report measures are widely used but often result in misreported height and weight and, consequentially, underestimation of BMI and—potentially—weight status misclassification. The purpose of this study was to examine differences in objective and self‐reported height, weight and BMI values and to find whether discordance is associated with other anthropometric measures, fitness and physical activity. Data were collected from college students through: (a) a pre‐consultation online questionnaire where participants self‐reported gender, height and weight; (b) an objective fitness assessment that assessed height, weight, body fat percentage, abdominal girth and predicted aerobic fitness; and (c) a post‐assessment electronic survey that assessed physical activity. Parametric and non‐parametric analyses examined differences between groups. Objective and self‐reported height and weight data were collected from 1061 participants, 224 of whom also provided physical activity data. Women significantly under‐reported weight (P = .003, η2 = 0.02), and both genders over‐reported height (P < .001, η2 ≥ 0.07), resulting in a significant difference between BMIs calculated using the different measures (P < .001, η2 ≥ 0.07) and the weight status misclassification of ~15% of participants. Significant differences were found in anthropometrics, fitness and physical activity based on reporting differences for weight (P ≤ .015) and BMI (P ≤ .015). Students demonstrated a tendency to under‐report weight and over‐report height, resulting in weight status misclassification. Those who under‐reported weight tended to be in poorer health as indicated by lower aerobic fitness and higher abdominal girth and body fat percentage in particular. Further research is required to establish the link between under‐reporting weight and over‐reporting physical activity.

Published: July 2019

AbstractAimPatients with inflammatory bowel disease and their physicians must navigate ever‐increasing options for treatment. The aim of this study was to elucidate the key drivers of treatment decision‐making in inflammatory bowel disease.MethodsWe conducted qualitative semi‐structured in‐person interviews of 20 adult patients undergoing treatment for inflammatory bowel disease at an academic medical centre who either recently initiated biologic therapy or underwent an operation or surgical evaluation. Interviews were audio‐recorded, transcribed verbatim, iteratively coded, and discussed to consensus by five researchers. We used thematic analysis to explore factors influencing decision‐making.ResultsFour major themes emerged as key drivers of treatment decision‐making: perceived clinical state and disease severity, the patient–physician relationship, knowledge, attitudes and beliefs about treatment options, and social isolation and stigma. Patients described experiencing a clinical turning point as the impetus for proceeding with a previously undesired treatment such as infusion medication or surgery. Patients reported delays in care or diagnosis, inadequate communication with their physicians, and lack of control over their disease management. Patients often stated that they considered surgery to be the treatment of last resort, which further compounded the complexity of making treatment decisions.ConclusionPatients described multiple barriers to making informed and collaborative decisions about treatment, especially when considering surgical options. Our study reveals a need for more comprehensive communication between the patient and their physician about the range of medical and surgical treatment options. We recommend a patient‐centred approach toward the decision‐making process that accounts for patient decision‐making preferences, causes of social stress, and clinical status.
