State estimation problems in PRF-shift magnetic resonance thermometry
Authors: Pacheco César , Orlande Helcio R.B. , Colaco Marcelo , Dulikravich George S. 
Published: January 2018

Purpose
The purpose of this paper is to apply the Steady State Kalman Filter for temperature measurements of tissues via magnetic resonance thermometry. Instead of using classical direct inversion, a methodology is proposed that couples the magnetic resonance thermometry with the bioheat transfer problem and the local temperatures can be identified through the solution of a state estimation problem.

Design/methodology/approach
Heat transfer in the tissues is given by Pennes’ bioheat transfer model, while the Proton Resonance Frequency (PRF)-Shift technique is used for the magnetic resonance thermometry. The problem of measuring the transient temperature field of tissues is recast as a state estimation problem and is solved through the Steady-State Kalman filter. Noisy synthetic measurements are used for testing the proposed methodology.

Findings
The proposed approach is more accurate for recovering the local transient temperatures from the noisy PRF-Shift measurements than the direct data inversion. The methodology used here can be applied in real time due to the reduced computational cost. Idealized test cases are examined that include the actual geometry of a forearm.

Research limitations/implications
The solution of the state estimation problem recovers the temperature variations in the region more accurately than the direct inversion. Besides that, the estimation of the temperature field in the region was possible with the solution of the state estimation problem via the Steady-State Kalman filter, but not with the direct inversion.

Practical implications
The recursive equations of the Steady-State Kalman filter can be calculated in computational times smaller than the supposed physical times, thus demonstrating that the present approach can be used for real-time applications, such as in control of the heating source in the hyperthermia treatment of cancer.

Originality/value
The original and novel contributions of the manuscript include: formulation of the PRF-Shift thermometry as a state estimation problem, which results in reduced uncertainties of the temperature variation as compared to the classical direct inversion; estimation of the actual temperature in the region with the solution of the state estimation problem, which is not possible with the direct inversion that is limited to the identification of the temperature variation; solution of the state estimation problem with the Steady-State Kalman filter, which allows for fast computations and real-time calculations.

Authors: Di Fraia Simona , Massarotti Nicola , Nithiarasu P. 
Published: January 2018

PurposeThis paper aims to provide a comprehensive literature review on modelling electro-osmotic flow in porous media.Design/methodology/approachModelling electro-osmosis in fluid systems without solid particles has been first introduced. Then, after a brief description of the existing approaches for porous media modelling, electro-osmotic flow in porous media has been considered by analysing the main contributions to the development of this topic.FindingsThe analysis of literature has highlighted the absence of a universal model to analyse electro-osmosis in porous media, whereas many different methods and assumptions are used.Originality/valueFor the first time, the existing approaches for modelling electro-osmotic flow in porous have been collected and analysed to provide detailed indications for future works concerning this topic.
The attitudinal and behavioral impact of brand-centered human resource management
Authors: Chiang Hsu-Hsin , Han Tzu-Shian , McConville David 
Published: January 2018

PurposeThe purpose of this paper is to investigate the effects of brand-centered human resource management (HRM) on employees’ person–brand fit, brand commitment (BC) and brand citizenship behavior (BCB). In addition, the paper tests effects of BCB on customer satisfaction and citizenship behavior.Design/methodology/approachData were collected from managers, front-line employees and customers of 22 international tourist hotels in Taiwan. Hierarchical linear modeling was used to investigate relationships between variables.FindingsMultilevel results reveal positive connections between brand-centered HRM and BCB, mediated by person–brand fit and BC. Positive relationships were also found between BC and BCB, person–brand fit and BCB; BCB and customer satisfaction; and between customer satisfaction and customer citizenship behavior.Research limitations/implicationsWhen employees’ personal values are consistent with brand values, employees will feel a closer connection to the brand and be more willing to dedicate themselves to brand-related activity. The model developed here can be tested in different cultures to ascertain the generalizability of the findings to Western contexts.Practical implicationsSupport is provided for the positive effects of brand-centered HRM when employees internalize brand values as their own personal values. Hotel managers should ensure that employees are highly committed to the brand values and willing to deliver services to customers accordingly.Originality/valueThe paper provides measurement developments for person–brand fit and BC and deeper understanding of how brand-centered HRM can lead to positive changes in customer behavior.
Drivers of consumers’ behavioral intention toward green hotels
Authors: Teng Chih-Ching , Lu Allan Cheng Chieh , Huang Tzu-Tang 
Published: January 2018

Purpose
The purpose of this study is to explore the relationships among consumers’ environmental value, low-carbon knowledge, perceived value of green hotels and behavioral intention to stay in green hotels as well as willingness to cooperate with green hotels’ environmentally friendly practices.

Design/methodology/approach
Structural equation modeling and indirect effect estimation through bootstrapping technique were performed using 415 valid questionnaires collected from customers who had green hotel stay experiences in Taiwan.

Findings
The analytical results indicate that environmental value and low-carbon knowledge positively affect perceived value of green hotels, which in turn positively affect consumers’ behavioral intention to stay in green hotels and willingness to cooperate with green hotels’ environmentally friendly practices. Perceived value of green hotels also partially mediates the effects of environmental value and low-carbon knowledge on two behavioral intention variables.

Practical implications
This study provides numerous valuable implications for green hotel operators to develop effective strategies to increase consumers’ perceived value of green hotels and their behavioral intention toward green hotels.

Originality/value
This study is among the first to test not only the main effects of environmental value and knowledge on consumer perceptions of the value of green hotels, but also the mediating effect of consumers’ perceived value of green hotels for the relationships between environmental value, environmental knowledge and two behavioral intentions toward green hotels.
High-performance work practices and hotel employee outcomes
Authors: Safavi Homayoun Pasha , Karatepe Osman M. 
Published: January 2018

PurposeThe purpose of this paper is to test career adaptability (CA) as an underlying mechanism linking high-performance work practices (HPWPs) to met expectations, creative performance and extra-role performance.Design/methodology/approachData were obtained from 313 customer-contact employees two weeks apart in three waves in the hotel industry in Iran. The proposed relationships were tested via structural equation modeling.FindingsEmployees who perceive that management offers various HPWPs display elevated levels of CA. These employees in turn find that their jobs have met their expectations. They exhibit higher creative and extra-role performances. In short, CA is a mediator between HPWPs and the aforementioned employee outcomes.Practical implicationsManagement should invest in HPWPs to enable employees to manage various work- and career-related demands. Management should also create an environment where employees can take advantage of career opportunities for growth and development. In this environment, employees can prepare themselves for the future in the current organization and gain new skills.Originality/valueWhat is known about the factors influencing Savickas’s (2005) notion of CA and CA influencing various employee outcomes is limited.

Authors: Diffley Sarah , McCole Patrick , Carvajal-Trujillo Elena 
Published: January 2018

Purpose
The purpose of this paper is to develop and test a model examining the key factors that emerge from the social customer relationship management (CRM) process. Specifically, this study aims to address the chain-of-effects that occurs as a result of the social CRM process, leading to superior levels of hotel performance.

Design/methodology/approach
Data were collected using a quantitative approach. Using a mail and online questionnaire, data were gathered from 120 key informants in hotels in Ireland. The proposed model was tested using partial least squares structural equation modelling.

Findings
Results demonstrate that the social CRM activities of hotels enhance hotel service innovation activities. This positively impacts the ability to develop a customer-linking capability, resulting in higher levels of customer performance. In turn, higher levels of customer performance leads to higher levels of financial performance.

Practical implications
Service innovation and customer-linking capability are identified as critical outcomes of the social CRM process that lead to enhanced hotel performance.

Originality/value
This study explains the chain-of-effects through which the social CRM process results in higher levels of performance.
Comparing customer perceptions of hotel and peer-to-peer accommodation advantages and disadvantages
Authors: Birinci Hasan , Berezina Katerina , Cobanoglu Cihan 
Published: January 2018

PurposeThe purpose of this paper is to compare customer perceptions of hotel and peer-to-peer (e.g. Airbnb) accommodation advantages and disadvantages and examine their influence on customer satisfaction and repurchase intentions. The advantages of each accommodation type are conceptualized through perceived travel experience authenticity, whereas the disadvantages are evaluated through the risks associated with staying at each accommodation type, including product performance risk, time/convenience risk and safety and security risk.Design/methodology/approachA cross-sectional survey was designed and disseminated to gather the data necessary to fulfill the study objectives. A total of 391 usable responses were collected for a multi-group analysis of the structural model designed to test the proposed relationships.FindingsThe multi-group comparison revealed similarities between the peer-to-peer (Airbnb) and hotel guest structural models. Model testing revealed a strong positive relationship between satisfaction and repurchase intention. Perceived authenticity was identified as a statistically significant satisfaction predictor for both accommodation types. Time/convenience and product performance risks were found to be insignificant predictors of guest satisfaction, while safety and security risk appeared to be statistically significant only in the Airbnb sample.Research limitations/implicationsThis study’s recruited sample represented a higher concentration of younger travelers, and, therefore, might only be generalized to the corresponding US traveler group population. Additionally, samples recruited via Amazon’s MTurk may be subject to self-selection bias as any other non-probability samples. Consequently, further research with a larger and more diverse sample is recommended.Practical implicationsIt is recommended for both hotels and Airbnb to strengthen the authenticity of their accommodation offerings to provide a better guest experience and increase consumer satisfaction.Social implicationsTo develop the authenticity component, Airbnb hosts and hotels may offer local experiences to their customers, where guests would be able to engage with the community and to see and feel how the city lives. Such partnerships may not only improve the traveler experiences but also support the local community and strengthen the ties between local businesses.Originality/valueThis study contributes to the literature by advancing understanding of peer-to-peer (Airbnb) versus hotel accommodation consumer preferences. This study offers relevant theoretical constructs for assessing both accommodation types’ advantages and disadvantages.
Customer knowledge sharing, creativity and value co-creation
Authors: Guan Xin-Hua , Xie Lishan , Huan Tzung-Cheng 
Published: January 2018

PurposeThis paper aims to improve understanding of co-creation by focusing on customer knowledge sharing (CKS), which is something that can be influenced by organizational relationship orientation (ORO), employee adaptiveness (EA) and customer expertise (CE), and that influences employee creativity (EC) and customer-perceived economic value (CEV).Design/methodology/approachWith subjects being conference and meeting organizers for hotel service, a survey was conducted in major Chinese cities. In the survey, high-star-rated hotels’ corporate sales personnel provided data if a sales person got one of their customers to provide data. Only responses for hotels for which two employee–customer matched records were obtained could be used for analysis by using hierarchical linear modeling; so, 217 matched records from 48 hotels were processed.FindingsAccepting five hypotheses and having coefficients for control variables allow new insights into the importance of CKS. Insights regarding brand familiarity, employee seniority, etc. contribute to theory and improving research.Practical implicationsAction can include fostering benefit from CE, nurturing EA and supporting ORO. Action can be recruiting and training employees with special considerations to their level and use of EA that facilitates acquiring valuable knowledge from customers. For researchers, practical implications relate to improving modeling and recognizing new research.Originality/valueThis study provides new findings on ORO, EA and CE affecting CKS, as well as showing relationships of CKS with EC and CEV. Coefficients of control variables yield insights beyond control that contribute to theory and to identifying new research. Examining response distributions highlights analysis issues, suggesting avenues for new research.
The moderating effect of identification on return on investment from sponsor brand integration
Authors: A. Jensen Jonathan , Walsh Patrick , Cobbs Joe 
Published: January 2018

PurposeThe achievement of a requisite return on investment (ROI) from a brand’s investment in sponsorships of sport events is becoming increasingly important. Consequently, evolving trends in the consumption of the live television broadcasts of such events (e.g. increased usage of second screens by consumers) are an important consideration. The purpose of this paper is to examine the impact of second screen use during sport broadcast consumption on important marketing outcomes (i.e. brand awareness and the perceived value and intrusiveness of sponsor brand integration), and whether effectiveness is dependent on the consumer’s level of identification with the sport being broadcast.Design/methodology/approachA 2×2 (experimental/control and high SportID/low SportID) between-subjects experimental design featuring the broadcast of a sport event as the stimuli was utilized to examine a potential interaction effect between sport identification and second screen use on three dependent variables important for sport sponsors.FindingsResults confirmed that those with a high level of sport identification realized significantly higher levels of brand awareness for sponsors integrated into the broadcast. However, when consumers were asked to engage in second screen use, the experiment revealed a moderating effect of sport identification on the impact of second screen use, for both brand awareness and the perceived value of the brand integration.Originality/valueConsumers with higher levels of sport identification are an important target of sport sponsorship activities by brand marketers. Given this, the implication that second screen use can reduce the effectiveness of important sponsorship-related outcomes such as brand awareness is a sobering result for marketers expecting a positive ROI from sponsorships of sport events.
Library resources, student success and the distance-learning university
Authors: Nurse Richard , Baker Kirsty , Gambles Anne 
Published: January 2018

Purpose
Research at the Open University Library Services has been investigating the relationship between access to online library resources and student success. The purpose of this study/paper is to help to understand whether there is a similar relationship at a distance-learning university to that found in other institutions.

Design/methodology/approach
A small library data project was established to investigate this area. The study analysed online library resource data from access logs from the EZproxy and OpenAthens systems. A data set of 1.7 million online resource accesses was combined with student success data for around 90,000 undergraduate students and a series of analyses undertaken.

Findings
The study found a pattern where students who are more successful are accessing more library resources. A chi-square test indicated a statistically significant association between library resource accesses and module result, while an ANOVA test suggests a medium-sized effect. The study also found that 152 (76 per cent) of the 199 modules had a small, medium or large positive correlation between student success, measured by the overall assessment score, and online library resource accesses.

Originality/value
This study builds on evidence that there is a relationship between library use and student success by showing that this relationship extends to the setting of a non-traditional, innovative library service supporting part-time distance learners.
Assessing the impact of libraries – the role of ISO 16439
Authors: Creaser Claire 
Published: January 2018

Purpose
Library impact and how to evaluate it has been debated for a number of years. While the activity – the busy-ness – of the library is now routinely measured and described, the difference the library makes is less tangible and harder to measure. Libraries in all sectors and worldwide are grappling with this issue, and the purpose of this paper is to summarise international standards available to support them.

Design/methodology/approach
The first international standard concerning library impact, ISO 16439 Information and documentation – methods and procedures for assessing the impact of libraries, was published in 2014 after several years in development.

Findings
The standard describes a range of methods for assessing library impact which have been used across the world in a variety of libraries in all sectors.

Originality/value
This paper summarises the key methods described in the standard, and gives references for further reading.
Principles and practice in impact assessment for academic libraries
Authors: Urquhart Christine 
Published: January 2018

Purpose
This paper aims to examine the principles that underpin library assessment, methods used for impact and performance evaluation and how academic libraries should use the findings, and it discusses how value frameworks help.

Design/methodology/approach
This is a literature review covering aspects of value (value propositions, value co-creation), value frameworks (including the 2015 ACRL framework, Holbrook typology with worked example), data analytics and collaborative projects including LibQUAL+ initiatives and the use of balanced scorecard principles (including a values scorecard).

Findings
The use of data analytics in library assessment requires collaboration among library services to develop reliable data sets. Scorecards help ongoing impact and performance evaluation. Queries that arise may require a framework, or logic model, to formulate suitable questions and assemble evidence (qualitative and quantitative) to answer new questions about the value of library services. The perceived value framework of Holbrook’s typology, the values scorecard and the ACRL framework all support the deeper level of inquiry required.

Research limitations/implications
Includes examples of possible application of frameworks.

Practical implications
A value framework might help data analytic approaches in combining qualitative and quantitative data.

Social implications
Impact assessment may require assessing how value is co-created with library users in use of e-resources and open data.

Originality/value
The study contrasts the varying approaches to impact evaluation and library assessment in academic libraries, and it examines more in-depth value frameworks.
Academic libraries break down silos
Authors: Massis Bruce 
Published: January 2018

Purpose
The purpose of this paper is to illustrate examples of the manner by which the academic library breaks down the silos on a college campus.

Design/methodology/approach
Literature review and commentary on this topic have been addressed by professionals, researchers and practitioners.

Findings
On a college campus, the value and impact of the academic library is today more than that of the standard model of libraries in which reference librarians offer available appropriate academic resources; but, the academic library is a place where the teaching and learning model of the standard model meets that of the support model to provide its users the best service by incorporating both aspects of the service.

Originality/value
The significance in exploring this topic is to provide evidence by which the academic library can and does offer a multitude of services that it can serve as the literal and physical center of a college campus.
