AbstractPhysical activity and exercise beneficially link to brain properties and cognitive functions in older adults, but it is unclear how these results generalise to other age groups. During adolescence, the brain undergoes significant changes, which are especially pronounced in white matter. Existing studies provide contradictory evidence regarding the influence of physical activity or aerobic-exercise on executive functions in youth. Little is also known about the link between both aerobic fitness and physical activity with white matter during puberty. For this reason, we investigated the connection between both aerobic fitness (20-m shuttle run) and physical activity (moderate-to-vigorous intensity physical activity) with white matter in 59 adolescents (12.7–16.2 years). We further determined whether white matter interacts with the connection of fitness or physical activity with three core executive functions (sustained attention, spatial working memory and response inhibition). Our results showed that only the level of aerobic fitness, but not of physical activity was related to white matter properties. Furthermore, the white matter of specific tracts also moderated the links of aerobic fitness and physical activity with working memory. Our results suggest that aerobic fitness and physical activity have an unequal contribution to the properties of white matter in adolescent brains. We propose that the differences in white matter properties could underlie the variations in the relationship between either physical activity or aerobic fitness with working memory.HighlightsAerobic fitness level, but not physical activity, is associated with white matter properties in several white matter tracts in the brain.The relationship between aerobic fitness and working memory was moderated by fractional anisotropy of the body of corpus callosum and in the right superior corona radiata.The relationship between physical activity and working memory was moderated by fractional anisotropy of the body and genu of corpus callosum.
Neural, functional, and aesthetic impacts of spatially heterogeneous flicker: A potential role of natural flicker
Authors: Menceloglu Melisa , Grabowecky Marcia , Suzuki Satoru 
Published: June 2019

AbstractSpatially heterogeneous flicker, characterized by probabilistic and locally independent luminance modulations, abounds in nature. It is generated by flames, water surfaces, rustling leaves, and so on, and it is pleasant to the senses. It affords spatiotemporal multistability that allows sensory activation conforming to the biases of the visual system, thereby generating the perception of spontaneous motion and likely facilitating the calibration of motion detectors. One may thus hypothesize that spatially heterogeneous flicker might potentially provide restoring stimuli to the visual system that engage fluent (requiring minimal top-down control) and self-calibrating processes. Here, we present some converging behavioral and electrophysiological evidence consistent with this idea. Spatially heterogeneous (multistable) flicker (relative to controls matched in temporal statistics) reduced posterior EEG (electroencephalography) beta power implicated in long-range neural interactions that impose top-down influences on sensory processing. Further, the degree of spatiotemporal multistability, the amount of posterior beta-power reduction, and the aesthetic responses to flicker were closely associated. These results are consistent with the idea that the pleasantness of natural flicker may derive from its spatiotemporal multistability that affords fluent and self-calibrating visual processing.

AbstractParental exposure to pathogens can prime offspring immunity in diverse organisms. The mechanisms by which this heritable priming occurs are largely unknown. Here we report that the soil bacteria Pseudomonas vranovensis is a natural pathogen of the nematode Caenorhabditis elegans and that parental exposure of animals to P. vranovensis promotes offspring resistance to infection. Furthermore, we demonstrate a transgenerational enhancement of progeny survival when three consecutive generations of animals are exposed to P. vranovensis. By investigating the mechanisms by which animals heritably adapt to P. vranovensis infection, we found that parental infection by P. vranovensis results in increased expression of the cysteine synthases CYSL-1 and CYSL-2 and the regulator of hypoxia inducible factor RHY-1 in progeny and that these three genes are required for adaptation to P. vranovensis. To our knowledge, these observations represent the largest heritable increase in offspring survival in response to a pathogen infection reported in any organism to date and establish a new CYSL-1, CYSL-2, and RHY-1 dependent mechanism by which animals adapt to infection.
Metrology characterization of ultraprecise bendable mirrors for the European XFEL: from offsite calibration to installation and commissioning
Authors: Vannoni Maurizio , Freijo Martín Idoia , Schmidtchen Silja , Baumann Thomas M. , Meyer Michael , Music Valerija 
Published: June 2019

The European XFEL requires long and ultraflat X-ray mirrors of high precision for the beam offset and distribution system [Altarelli et al. (2006), XFEL Technical Design Report, DESY 2006-097. DESY, Hamburg, Germany]. A general specification of the beam transport mirrors is a length of up to 950 mm and an optical surface with a deviation from a perfectly flat surface of <30 nm peak-to-valley and a figure error of <2 nm peak-to-valley. From a production point of view, such a mirror cannot be easily fabricated so, in each beamline, it is foreseen to have at least one mirror with bending capabilities. In this way, it is possible to correct the residual divergence of the beam in order to focus it in the correct position with high accuracy and repeatability. This is practically implemented using a mechanical bender in which the mirror is mounted and bent through a motorized actuator. One such system was characterized in the metrology lab using a large-aperture Fizeau interferometer and a capacitive sensor. It was then installed in the beamline and calibrated again using the X-ray beam. Here, the procedure is described and the two different methods are compared, stressing the differences and the possible explanations and improvements.
Museums, heritage and the politics of pursuing indigenous rights in Taiwan
Authors: Wang Shu-Li 
Published: June 2019

Purpose
The purpose of this paper is to trace the development of indigenous heritage rights in Taiwan. It examines how this pursuit is intertwined with the global indigenous movement, national political interests and rising local cultural awareness.

Design/methodology/approach
This paper focuses on the rise of indigenous rights in Taiwan by looking at political shifts, indigenous museums and changing frameworks through which heritage is understood. The paper uses two case studies: one is the implementation of a heritage protection law in Taiwan; the other is the launch of indigenous museums.

Findings
In Taiwan, heritage is often associated with political ideology, power relations and resource distribution. The development of heritage discourse is inseparable from the international heritage trend as well as the local political situation.

Originality/value
The pursuit of indigenous heritage rights in Taiwan is supported on the one hand by the government so as to define a distinctive Taiwanese culture and on the other to meet the demands of Taiwan’s indigenous movement. Two case studies are provided to examine the pros and cons of current indigenous heritage projects in Taiwan.
Scientometric analysis of BIM-based research in construction engineering and management
Authors: Jin Ruoyu , Zou Yang , Gidado Kassim , Ashton Phillip , Painting Noel 
Published: June 2019

PurposeThe purpose of this paper is to summarize the latest research of BIM adoption in construction engineering and management (CEM) and propose research directions for future scholarly work. During the recent decade, building information modeling (BIM) has gained increasing applications and research interest in the construction industry. Although there have been review-based studies that summarized BIM-based research in the overall architecture, engineering and construction (AEC) area, there is limited review that evaluates the current stage of BIM-based research specifically in the CEM sub-area.Design/methodology/approachCEM falls into the scope of AEC. It involves construction-related tasks, activities and processes (e.g. scheduling and cost estimates), issues (e.g. constructability), as well as human factors (e.g. collaboration). This study adopted a holistic literature review approach that incorporates bibliometric search and scientometric analysis. A total of 276 articles related to BIM applied in CEM were selected from Scopus as the literature sample for the scientometric analysis.FindingsSome key CEM research areas (e.g. CEM pedagogy, integrated project delivery, lean and off-site construction) were identified and evaluated. Research trends in these areas were identified, and analyses were carried out with regard to how they could be integrated with BIM. For example, BIM, as a data repository for ACE facilities, has substantial potential to be integrated with a variety of other digital technologies, project delivery methods and innovative construction techniques throughout the whole process of CEM.Practical implicationsAs BIM is one of the key technologies and digital platforms to improve the construction productivity and collaboration, it is important for industry practitioners to be updated of the latest movement and progress of the academic research. The industry, academics and governmental authorities should work with joint effort to fill the gap by first recognizing the current needs, limitations and trends of applying BIM in the construction industry. For example, it needs more understanding about how to address technical interoperability issues and how to introduce the integrated design and construction delivery approach for BIM implementation under the UK BIM Level 2/3 framework.Originality/valueThis study contributed to the body of knowledge in BIM by proposing a framework leading to research directions including the differences of BIM effects between design-bid-build and other fast-track project delivery methods; the integration of BIM with off-site construction; and BIM pedagogy in CEM. It also addressed the need to investigate the similarities and differences between academia and industry toward perceiving the movement of BIM in construction field work.
Tourists’ intention to use location-based services (LBS)
Authors: Meng Bo , Choi Kyuhwan 
Published: June 2019

Purpose
This study aims to investigate the tourists’ intentions to use LBS within a tourism sector by integrating the elaboration likelihood model (ELM) into the framework of the theory of planned behavior (TPB).

Design/methodology/approach
This study is conducted by an online survey and a snowball sampling method with 353 respondents. The present study used a two-step method suggested by Anderson and Gerbing’s (1988).

Findings
Study results from structural equation modeling (SEM) revealed that the new model has a better predictive ability. Additionally, study results from SEM demonstrated the causal relationships in the proposed model and identified a mediating role of attitude. Further, the moderating effects of involvement across the different relationships in ELM were also verified.

Originality/value
This study is the first to explain individuals’ decision-making process by using the TPB framework with the integration of meaningful constructs rooted in ELM. Therefore, the study results help the tourist application developers to use better marketing and service strategies through effective management of tourists’ central routes, peripheral routes, normatives and non-volitional processes of tourism LBS decision-making.
The effect of management response similarity on online hotel booking
Authors: Zhang Zili , Li Hengyun , Meng Fang , Li Yuanshuo 
Published: June 2019

Purpose
This paper aims to examine the influences of the number of hotel management responses and especially the textual similarity in hotel management responses to online reviews on hotel online booking.

Design/methodology/approach
This study used the data from 437 hotels in New York City on Expedia. The data specifically include online reviews, management responses and real-time number of online hotel bookings, which were merged to create one dataset for this study. To calculate the management response similarity, three widely recognized text mining functions of calculating textual similarity were adopted in this model. Fixed-effect panel data model was then used to examine the influence of management response to consumer online reviews on online hotel booking volume.

Findings
The empirical results demonstrate that the number of management responses to consumer online reviews does not significantly affect hotel booking; compared to none or only one management response, or management responses with low similarity, management responses with high similarity can significantly reduce the hotel booking on Expedia.

Practical implications
This study suggests that the similarity of management responses influences customers’ hotel booking, and hotel managers should avoid providing too similar management responses.

Originality/value
First, this study, for the first time, proposes the concept of management response similarity and its measurement methods. Second, this study takes an initial attempt to empirically test the influence of response similarity on hotel booking by using secondary data online.
Talent management dimensions and their relationship with retention of Generation-Y employees in the hospitality industry
Authors: Gupta Vikas 
Published: June 2019

Purpose
The purpose of this paper is to determine the causal relationship between talent management dimensions such as Human Capital Index and perceived organizational support (POS) and the impact thereof on the turnover intentions of Generation-Y employees. This study tries to find out how the intensions of employees to quit relates significantly to the talent management practices in Indian hospitality organizations.

Design/methodology/approach
This study proposed an integrated conceptual model based on previous literature where the relationship between the relevant constructs is verified. A cross-sectional survey design is used for data collection, which is ideally suited for the descriptive and predictive functions associated with correlation research and for assessing the interrelationship among various variables in the study.

Findings
Pearson’s correlations showed a practically significant positive relationship between the organization’s talent management practices and POS. It is also inferred that perceived supervisory support does not mediate the relationship between talent management practices and intention to quit. The findings of this study also confirm that employees’ perception of the organization’s actions has direct effects on their perception of support from their supervisors. The study also found a practically significant negative relationship between POS and the employee’s intention to quit, where high levels of POS are associated with a decreased intention to quit the organization.

Originality/value
From a theoretical aspect, this study provided a quantitative method for assessing the Generation-Y employees’ perceptions in relation to other relevant constructs. Practically, this study provided a framework for the management to understand that the perceptions regarding talent practices and support influence an employee’s intent to leave an organization.
Silhouette and handle design of cotton crepe fabrics for dresses
Authors: Yokura Hiroko , Sukigara Sachiko 
Published: June 2019

Purpose
For over a century, traditional Japanese cotton crepe fabrics have been popular for men’s underwear in the humid summer. Now, consumer demand is for crepe fabrics that are more attractive, reflecting a shift in use from underwear to women’s dresses. The purpose of this paper is to clarify how the structures of the crepe and its constituent yarns affect the physical properties, handle and silhouette formability of crepe fabrics for dresses.

Design/methodology/approach
Three plain-weave gray fabrics were finished by four different processes to change their crepe structures. The mechanical and surface properties of the fabrics were measured using the Kawabata evaluation system for fabrics. The primary hand values and silhouette formability of the fabrics were calculated using conversion equations based on the physical properties. The handle of the crepe fabrics and the aesthetic appearance of flared collars made of them were assessed by female students using the semantic differential method.

Findings
Comparing the fabrics made from the same gray fabric, the piqué crepe fabrics showed larger Hari (anti-drape) and Shari (crispness) than the others. The subjective hand value of softness was closely related to fabric thickness. The assessors preferred the fine piqué crepe fabrics over the wide piqué fabrics regarding both the tactile feeling of the fabrics and the aesthetic appearance of the flared collars. The attractiveness of the flared collars was dominated by the shear stiffness of the fabrics.

Originality/value
The fine piqué crepe fabric made from fine yarns produced a more preferable handle. The fine piqué fabric made from thicker yarns produced flared collars with silhouettes that are more attractive. This indicates that the fine piqué structure is a positive feature that makes the fabric suitable for various types of dresses.
Improving the effectiveness of fire prevention using the “premonition” agent-based model of domestic fire risk behaviours
Authors: Breslin Dermot , Dobson Stephen , Smith Nicola 
Published: June 2019

Purpose
Understanding and predicting the behaviours of households within a community is a key concern for fire services as they plan to deliver effective and efficient public services. In this paper, an agent-based modelling approach is used to deepen understandings of changing patterns of behaviour within a community. The paper aims to discuss this issue.

Design/methodology/approach
This “Premonition” model draws on historical data of fire incidents and community interventions (e.g. home safety checks, fire safety campaigns, etc.) collated by South Yorkshire Fire and Rescue, UK, to unpack patterns of changing household behaviours within the region.

Findings
Findings from simulations carried out using the Premonition model, show that by targeting close-knit groups of connected households, the effectiveness of preventative interventions and utilisation of associated resources is enhanced. Furthermore, by repeating these interventions with the same households over time, risk factors within the wider area are further reduced.

Originality/value
The study thus shows that annual repeat visits to fewer and more targeted high-risk postcodes increase the overall reduction in risk within an area, when compared with a scattered coverage approach using one-off (i.e. not repeat) household visits within a postcode.

Dementia-friendly design of television news broadcasts
Authors: Funnell Liam , Garriock Isabel , Shirley Ben , Williamson Tracey 
Published: June 2019

Purpose
The purpose of this paper is to understand factors that affect viewing of television news programmes by people living with dementia, and to identify dementia-friendly design principles for television news programmes and factors for personalising object-based media broadcast.

Design/methodology/approach
Extensive public involvement comprising two discussion groups with people with dementia and family carers informed the study design and provided supplementary secondary data. Primary data collection comprised a focus group interview with people with dementia (n=4) and family carers (n=4). Past viewing experiences and perceived barriers and facilitators to viewing television were explored. Participants commented on an array of video clips comprising varying segments of fictional news programmes, plus control versions of each segment.

Findings
Four themes were identified: content (general comments, context, type of media and pace); presenter (body language, clothing and accent); background (location and studio appearance); and technical aspects (graphics, sound, colours, camera, transitions, general issues).

Research limitations/implications
Limitations included a modest sample size which is offset by exemplary public involvement in informing the study design.

Practical implications
Measures ensured research involvement and participation was made accessible to people living with dementia.

Social implications
Participants benefited from sharing views with peers and expressed enhanced wellbeing from knowing their participation could lead to improved television viewing, an important social occupation, for people with dementia in the future.

Originality/value
This study is the first to be published which focusses on dementia-friendly television news programmes.
