Published: June 2019

AbstractThe maturation of photon-counting detector (PCD) technology promises to enhance routine CT imaging applications with high-fidelity spectral information. In this paper, we demonstrate the power of this synergy and our complementary reconstruction techniques, performing 4D, cardiac PCD-CT data acquisition and reconstruction in a mouse model of atherosclerosis, including calcified plaque. Specifically,in vivocardiac micro-CT scans were performed in four ApoE knockout mice, following their development of calcified plaques. The scans were performed with a prototype PCD (DECTRIS, Ltd.) with 4 energy thresholds. Projection sampling was performed with 10 ms temporal resolution, allowing the reconstruction of 10 cardiac phases at each of 4 energies (40, 3D volumes per mouse scan). Reconstruction was performed iteratively using the split Bregman method with constraints on spectral rank and spatio-temporal gradient sparsity. The reconstructed images represent the firstin vivo, 4D PCD-CT data in a mouse model of atherosclerosis. Robust regularization during iterative reconstruction yields high-fidelity results: an 8-fold reduction in noise standard deviation for the highest energy threshold (relative to algebraic reconstruction), while absolute spectral bias measurements remain below 13 Hounsfield units across all energy thresholds and scans. Qualitatively, image domain material decomposition results show clear separation of iodinated contrast and soft tissue from calcified plaque in thein vivodata. Quantitatively, spatial, spectral, and temporal fidelity are verified through a water phantom scan and a realistic MOBY phantom simulation experiment: spatial resolution is robustly preserved by iterative reconstruction (10% MTF: 2.8-3.0 lp/mm), left-ventricle, cardiac functional metrics can be measured from iodine map segmentations with ∼1% error, and small calcifications (615 μm) can be detected during slow moving phases of the cardiac cycle. Given these preliminary results, we believe that PCD technology will enhance dynamic CT imaging applications with high-fidelity spectral and material information.
Nonlinear Dispersive Cell Model for Microdosimetry of Nanosecond Pulsed Electric Fields
Authors: Guo Fei , Zhang Lin , Liu Xin 
Published: June 2019

AbstractFor nanosecond pulsed electric fields (nsPEFs) based application, the underlying transmembrane potential (TMP) distribution of the plasma membrane is influenced by electroporation (EP) of the plasma membrane and dispersion (DP) of all cell compartments and is important for predicting the bioelectric effects. In this study, we analysed temporal and spatial distribution of TMP induced by nsPEFs of various durations (3 ns, 5 ns unipolar, 5 ns bipolar, and 10 ns) with the consideration of both DP and EP. Based on the double-shelled dielectric spherical cell model, we used second-order Debye equation to characterize the dielectric relaxation of plasma membrane and nuclear membrane in the frequency domain and transformed the Debye equation into the time domain with the introduction of polarization vector, then we obtained the time course of TMP by solving the combination of Laplace equation and time-domain Debye equation. Next, we used the asymptotic version of the smoluchowski equation to characterize electroporation of plasma membrane and added it to our model to achieve the temporal and spatial distribution of TMP and pore density. Much faster and more pronounced increased in TMP can be found with the consideration of dielectric relaxation of plasma membrane and nuclear membrane, and much larger electroporated area of at least half of the plasma membrane was obtained with the consideration of both DP and EP. Through the simulation it is clearer to understand the relationship.
Planning to revisit: neural activity in refixation precursors
Authors: Nikolaev Andrey R. , Ehinger Benedikt V. , Meghanathan Radha Nila , Leeuwen Cees van 
Published: June 2019

AbstractEye tracking studies suggest that refixations, fixations to locations previously visited, serve to recover information lost or missed during earlier exploration of a visual scene. These studies have largely ignored the role of precursor fixations, previous fixations on locations the eyes return to later. We consider the possibility that preparations to return later are already made during precursor fixations. This would mark precursor fixations as a special category of fixations, i.e., distinct in neural activity from other fixation categories such as refixations and fixations to locations visited only once. To capture the neural signals associated with fixation categories, we analyzed EEG and eye movement recorded simultaneously in a free-viewing contour search task. We developed a methodological pipeline involving regression-based deconvolution modeling, allowing our analyses to account for overlapping EEG responses due to the saccade sequence and other oculomotor covariates. We found that precursor fixations were preceded by the largest saccades among the fixation categories. Independently of the effect of saccade length, EEG amplitude was enhanced in precursor fixations compared to the other fixation categories 200-400 ms after fixation onsets, most noticeably over the occipital areas. We concluded that precursor fixations play a pivotal role in visual perception, marking the continuous occurrence of transitions between exploratory and exploitative modes of eye movement in natural viewing behavior.
The cultural non-participant: critical logics and discursive subject identities
Authors: Stevenson David 
Published: June 2019

Purpose
The existence of so-called non-participants is a cultural policy problem in the UK and beyond. Yet, the very notion of a cultural non-participant seems nonsensical against the palpable evidence of lived experience. The purpose of this paper is to understand “who” a cultural non-participant is by first comprehending “what” the cultural non-participant is and why it exists.

Design/methodology/approach
Drawing on primary data generated in the form of 40 in-depth qualitative interviews, this paper employs a discursive methodology to explore the critical logics (Howarth, 2010) that underlie the problem representation (Bacchi, 2009) of cultural non-participation and in particular the discursive subject identity of the cultural non-participant.

Findings
Beginning with a discussion about how cultural non-participants are represented as socially deprived and hard to reach, the paper moves on to highlight how they are also presumed to lack knowledge and understanding about what they are rejecting. Their supposed flawed subjectivity is then contrasted with the desirable model of agency claimed by the cultural professionals who seek to change the cultural participation patterns of others. The paper concludes with a consideration of how the existence of the cultural non-participant subject identity limits the extent to which those labelled as such can meaningfully contribute to the field of cultural policy and obscures the extent to which such individuals are culturally disenfranchised.

Research limitations/implications
Because of the chosen research approach and the geographical limitations to the data generation, the research makes no claim to generalisability. Therefore, researchers are encouraged to test the discursive logics identified at alternative discursive sites.

Practical implications
This paper proposes a change in the language used by cultural professionals accompanied by changes in practice that abandoning the identity of the cultural non-participant would demand.

Originality/value
This paper challenges a taken for granted assumption that cultural non-participants exist “in the real”.
The critical music fan: the role of criticality in collective constructions of brand loyalty
Authors: Obiegbu Chinedu James , Larsen Gretchen , Ellis Nick 
Published: June 2019

PurposeThe purpose of this paper is to explore how the act of expressing criticism against a music brand fits with the identity and practices associated with being a loyal fan of that brand.Design/methodology/approachDrawing on insights from theories of brand loyalty and fandom, this interpretive inquiry makes use of data from an online forum dedicated to the band, U2, and interviews with forum members. A combination of online ethnography and discourse analysis is employed.FindingsThe findings reveal how interpretations of the act of expressing criticism within a space that ostensibly functions as a place to celebrate all things U2 related, shape the construction of loyalty to the b(r)and in diverse ways. The apparent in-group tensions between being loyal and being critical pose a challenge to the taken for granted nature of brand loyalty and fandom, highlighting the nuanced ways with which they manifest.Originality/valueBy examining the role of criticality within otherwise loyal spaces, the authors contribute to brand loyalty theory by revealing the malleability of the concept, as meaning is constantly being reshaped depending on individual realities.
What price beauty! Tourists willingness-to-pay for cherry blossom preservation
Authors: Sussan Fiona , Nakagawa Hideyuki 
Published: June 2019

Purpose
Mapping the intrinsic value of the art of architecture and the art of nature within the context of Kakunodate and the preservation of its samurai manors and Sakura heritage trees, this paper proposes that from the perception of tourists, the preservation of both items is important. Extending the psychology of pricing that is subject to consumers’ preference and expectation to the context of valuation of cultural heritage assets, the purpose of this paper is to suggest that including the art of nature and the aesthetic of Sakura to the art of architecture (Samurai manors) will add more value to the cultural heritage of Kakunodate than when only the art of architecture is mentioned.

Design/methodology/approach
This paper uses Contingency Valuation Method to solicit tourists willingness-to-pay to preserve the architecture and the nature in Kakunodate. The survey uses a double bounded dichotomous choice model to elicit the various levels of tourists preference in various scenarios. Response from more than 1,000 tourists in three scenarios were collected. Through a maximum likelihood method and a subsequent truncated calculation, results are reported.

Findings
The results support the conceptual argument that the art of nature adds value to the art of architecture only. Tourists are found to be willing to pay more to support both the architecture (samurai houses) and nature (cherry trees) than the samurai houses alone.

Research limitations/implications
The research findings add to the inventory of research on prior works in heritage trees, conservation of trees and heritage tourism, and cultural heritage assets in general. The empirical findings support prior theoretical works that examined the relationship of nature and art, art and architecture, and architecture as visual consumption.

Practical implications
The findings have managerial implications for policy makers relative to a possible increase of revenue by adding accompanying-nature component to focal architectural assets when soliciting funding support.

Originality/value
The originality and this piece stems from extending trees as an art form in nature and its added value to architecture within the context of cultural heritage assets. The empirical findings add to the much discussed relationships among art, nature, and architecture.
Implementation and challenges of accreditation of prior experiential learning: admissions (APEL-A)
Authors: Ooi Li Hsien , Din Eak Arathai 
Published: June 2019

Purpose
The purpose of this paper is to highlight how accreditation of prior experiential learning (APEL) is implemented, the challenges faced by the APEL assessors while assessing candidates as well as to suggest recommendations for improving the APEL process.

Design/methodology/approach
This paper is written based on the critical reflection of two accreditation of prior experiential learning: admissions (APEL-A) assessors appointed from a Malaysian Qualifications Agency approved assessment centre. This process would add depth and breadth to the study based on the assessor’s experience.

Findings
The study identified five challenges in the implementation of APEL-A. They are limited literature and records of the existing practices, conceptualisation of the APEL process, complicated and time-consuming APEL process, standard of acceptance vary according to discipline and lack of continuous training for APEL assessors. The four recommendations for improvements are as follows: the need for transparent and clear guidelines, ensuring consistency in practices and fairness to those from conventional learning, integrating APEL as part of the institution’s academic policy and providing continuous training for all APEL assessors.

Originality/value
Until now, not much research has been done regarding its implementation in Malaysia. The number of learners enrolled through this form of assessment may be low but growing. The feedback on the implementation of the APEL-A assessment process would be greatly beneficial to the stakeholders involved in improving its implementation process. The highlighted challenges faced as well as the recommendations put forth may also be useful for the continuous improvement of the APEL-A assessment process. Relevant stakeholders would benefit from this study.
Complexity of women’s modern-day challenges in construction
Authors: Aboagye-Nimo Emmanuel , Wood Hannah , Collison Jodie 
Published: June 2019

Purpose
Although the UK construction sector has enjoyed a significant rise in the number of women joining the industry, there is undoubtedly more room for improvement. Numerous schemes have been initiated by government and other professional bodies to encourage more women to undertake a career in construction. The purpose of this paper is to shed light on the organisational complexities of problems faced by women working in professional roles in construction. It thus initiates a dialogue on the lack of workplace flexibility and discriminatory practices that prevent many more women from joining.

Design/methodology/approach
A phenomenological philosophy is adopted. The research critically explores the views of women working in professional roles in six large construction firms in England.

Findings
It was widely acknowledged that the industry had improved significantly, however there are still concerns yet to be addressed. It was identified that women face new challenges when they attain senior roles. Furthermore, it is believed that the current glass ceiling theory and leaky pipeline theory are not adequate to study these issues.

Research limitations/implications
Sample size and narrow focus on large construction firms are the limitations of the paper.

Practical implications
Through academic and industry dissemination, the findings from this research encourage both men and women working in the construction industry to adopt inclusive practices that will help widen the pool of knowledge and expertise.

Social implications
This paper sheds light on a problem that is assumed to be eradicated once women progress to senior management roles.

Originality/value
This research presents an in-depth critical perspective of challenges faced by women construction professionals occupying decision-making positions.
Managing production pressures through dangerous informality: a case study
Authors: Oswald David , Sherratt Fred , Smith Simon 
Published: June 2019

Purpose
It is well-known that significant production pressures exist on many construction projects and previous studies have suggested that this pressure is a contributory factor in safety incidents on sites. While research has established that production pressures exist, less is understood about the construction practices that occur when projects are under such pressures and their repercussion for safety. The paper aims to discuss this issue.

Design/methodology/approach
Through an ethnographic approach on a large construction project in the UK, these practices were explored and unpacked. The lead researcher was a member of the Health and Safety department, and undertook participant observation as a main research tool for three years.

Findings
It was found that informal, covert and dangerous “piecework” strategies were adopted at the site level in direct response to scheduling demands. Construction workers were incentivised through extra finance and rest periods to finish the work quickly, which, in turn, prioritised production over safety. Unreasonable production pressures remain an unresolved problem in the construction industry and are, perhaps consequentially, being informally managed on-site.

Originality/value
This study improves our understanding of the complexities involved in the unresolved demands between production and safety on construction sites, which marks a step towards addressing this substantial challenge that is deeply ingrained within the industry.
Green hotel adoption: a personal choice or social pressure?
Authors: Balaji M.S. , Jiang Yangyang , Jha Subhash 
Published: June 2019

Purpose
This study aims to examine the potential guest perception of green hotel attributes (GHAs) and the underlying mechanism through which GHA perception influences attitude toward green hotels, intention to stay at green hotels and willingness to pay a premium. It also investigates the moderating roles of personal norms and social norms in the influence of GHA perception on identification and trust toward green hotels.

Design/methodology/approach
A two-stage survey was used to collect data via Prolific Academic. The authors tested the hypotheses on 521 valid responses using the partial least squares method.

Findings
The results show that identification and trust mediate the effect of GHA perception on attitude, intention to stay and willingness to pay a premium for green hotels. The authors found a positive interaction effect between GHA perception and personal norms on identification and trust and a negative interaction effect between social norms and GHA perception on trust. The interaction effect of GHA perception and social norms on identification is not significant.

Originality/value
This study presents an integrated framework for green hotel adoption by examining the potential guest perception of GHAs and explores how it fosters positive guest responses. Findings show that GHA perception positively influences potential guest responses through identification (the personal route) and trust (the social route). This study also simultaneously considers personal norms and social norms, together with the effects of their interactions with GHA perception on identification and trust.
Using Learning Analytics to evaluate the quality of multiple-choice questions
Authors: Azevedo Jose Manuel , Oliveira Ema P. , Beites Patrícia Damas 
Published: June 2019

Purpose
The purpose of this paper is to find appropriate forms of analysis of multiple-choice questions (MCQ) to obtain an assessment method, as fair as possible, for the students. The authors intend to ascertain if it is possible to control the quality of the MCQ contained in a bank of questions, implemented in Moodle, presenting some evidence with Item Response Theory (IRT) and Classical Test Theory (CTT). The used techniques can be considered a type of Descriptive Learning Analytics since they allow the measurement, collection, analysis and reporting of data generated from students’ assessment.

Design/methodology/approach
A representative data set of students’ grades from tests, randomly generated with a bank of questions implemented in Moodle, was used for analysis. The data were extracted from a Moodle database using MySQL with an ODBC connector, and collected in MS ExcelTM worksheets, and appropriate macros programmed with VBA were used. The analysis with the CTT was done through appropriate MS ExcelTM formulas, and the analysis with the IRT was approached with an MS ExcelTM add-in.

Findings
The Difficulty and Discrimination Indexes were calculated for all the questions having enough answers. It was found that the majority of the questions presented values for these indexes, which leads to a conclusion that they have quality. The analysis also showed that the bank of questions presents some internal consistency and, consequently, some reliability. Groups of questions with similar features were obtained, which is very important for the teacher to develop tests as fair as possible.

Originality/value
The main contribution and originality that can be found in this research is the definition of groups of questions with similar features, regarding their difficulty and discrimination properties. These groups allow the identification of difficulty levels in the questions on the bank of questions, thus allowing teachers to build tests, randomly generated with Moodle, that include questions with several difficulty levels in the tests, as it should be done. As far as the authors’ knowledge, there are no similar results in the literature.
An exploratory study of discharge planning home visits within an Irish context – investigating nationwide practice and nationwide perspectives
Authors: Davis Aisling Jane , Mc Clure Patricia 
Published: June 2019

Purpose
Discharge planning home visits (DPHVs) are a routine part of occupational therapy clinical practice. However, there is a dearth of evidence to support or refute their efficacy and limited policies or standards to guide clinical practice. This study aims to investigate current clinical practice during home visits and the value that occupational therapists’ attribute to home visits within an Irish context.

Design/methodology/approach
Data collection was carried out by using a survey questionnaire (postal and electronic options). The study population comprised occupational therapists across 52 sites including acute, rehabilitation and convalescence settings within the Republic of Ireland. In total, 122 occupational therapists that completed the survey questionnaire were recruited for the study.

Findings
Quantitative data identified time spent per visit, departmental size, hospital size, number of visits and report writing times. Information was gathered regarding clinical areas assessed during visits in a Likert scale format. Qualitative data identified benefits, risks, recommendations to improve home visit practice and clinical criteria for home visits. Findings conclude that DPHVs are routinely carried out by occupational therapists and that there is consistency in clinical practice within an Irish setting. Occupational therapists value home visits as clinical assessments and have identified risks during practice, benefits of visits and ways to improve practice.

Originality/value
This study has provided a reflection of clinical practice in the Republic of Ireland. It is the only study of its kind in an Irish setting, and it could be used as a knowledge base regarding current practice on DPHV and occupational therapists’ clinical reasoning regarding home visits. The information gathered in this study could influence policies regarding DPHV and could serve as a comparison to standardise practice and justify the need for DPHV.
