The Impact

Purpose The paper aims to present an innovative solution for evaluation study of the dampness level of walls and historical buildings. Design/methodology/approach Electrical tomography enables one to obtain a distribution pattern of wall dampness. The application of modern tomographic techniques in conjunction with topological algorithms will allow one to perform very accurate spatial assessment of the dampness levels of buildings. The proposed application uses the total variation, Gauss–Newton and level set method to solve the inverse problem in electrical tomography. Findings Research shows that electrical tomography can provide effective results in damp buildings. This method can provide 2D/3D moisture distribution pattern. Research limitations/implications The impact of this technique will be limited to inspection of the facility after floods or assessment of historical buildings. Practical implications The presented method could eventually lead to a much more effective evaluation of moisture in the walls. Social implications The solution has commercial potential and could result in more cost-effective monitoring of historical buildings, which have an economic impact on society. Originality/value The authors propose a system for imaging spatial moistness of walls and historic buildings based on electrical tomography and consisting of a measuring device, sensors and image reconstruction algorithms.

Purpose This paper aims to assess the level of occupants’ satisfaction, comparing older and newer on-campus accommodation buildings in Sydney, Australia, aiming to identify their comfort factors deficiencies in terms of design and construction solutions/strategies (e.g. spatial arrangements, materials, thermal comfort). Design/methodology/approach A post occupancy evaluation survey was used to assess the occupant satisfaction with three on-campus accommodation buildings in The University of New South Wales (UNSW) Sydney. One of the selected buildings is an older building opened for occupation in 1996, and the other two are more recent on campus accommodations buildings. The survey included 11 post occupancy evaluation elements identified through literature review which were categorised into three dimensions: technical, functional and behavioural. Findings The results show that the satisfaction levels with thermal and acoustic comfort were below standards for both older and newer buildings. In addition, the older building used in this study was rated low in terms of: indoor air quality, lighting, maintenance and management, vertical transportation facility, room layout and furniture quality, building layout and aesthetics and level of privacy. Such factors related to both functional and behavioural dimensions were of greater satisfaction in newer buildings. Practical implications Findings suggest the high priority of strategies that address and improve the thermal and acoustic comfort of older and newer on-campus accommodation buildings if the intention is to enhance students’ satisfaction, especially considering the impact that these facilities have on students’ performance. Thermal performance in different seasons and adaptive thermal comfort activities should be considered in the design of new on-campus accommodation buildings and the retrofit of existing old buildings. Originality/value On-campus accommodation is an important facility that supports student learning outcomes and helps students adapt in a new learning environment. A post occupancy evaluation study to assess the adequacy of this facility is still lacking because previous studies have generally focussed on class rooms and work spaces in the education sector. This research compares the user satisfaction of older and newer on-campus accommodation buildings in Australia, to highlight deficiencies and areas for improvement in the design of existing and future buildings.

PurposeThe purpose of this paper is to demonstrate the rationale, technical framework, content creation workflow and evaluation for a multilingual massive open online course (MOOC) to facilitate information literacy (IL) considering cultural aspects.Design/methodology/approachA good practice analysis built the basis for the technical and content framework. The evaluation approach consisted of three phases: first, the students were asked to fill out a short self-assessment questionnaire and a shortened adapted version of a standardized IL test. Second, they completed the full version of the IL MOOC. Third, they were asked to fill out the full version of a standardized IL test and a user experience questionnaire.FindingsThe results show that first the designed workflow was suitable in practice and led to the implementation of a full-grown MOOC. Second, the implementation itself provides implications for future projects developing multilingual educational resources. Third, the evaluation results show that participants achieved significantly higher results in a standardized IL test after attending the MOOC as mandatory coursework. Variations between the different student groups in the participating countries were observed. Fourth, self-motivation to complete the MOOC showed to be a challenge for students asked to attend the MOOC as nonmandatory out-of-classroom task. It seems that multilingual facilitation alone is not sufficient to increase active MOOC participation.Originality/valueThis paper presents an innovative approach of developing multilingual IL teaching resources and is one of the first works to evaluate the impact of an IL MOOC on learners' experience and learning outcomes in an international evaluation study.

Purpose The purpose of this paper is to investigate the wear resistance behavior of the striated tool for cross wedge rolling (CWR). Design/methodology/approach A mechanical-thermal coupled, temperature-dependent FE wear model was developed to explore the wear behaviors for striated CWR tools. To verify the proposed FE model, a newly developed measuring device was also developed to measure wear on the tool ridge. To find the impact order of the parameters of striate unit, orthogonal experiment was carried out. Findings The experimental and numerical results both indicate that the wear resistance of striated tool is better than that of smooth tool. Minimum tool ridge wear can be achieved by choosing proper tool contact temperature with striated units on crossed ridge. The order of the striation geometrical factors’ impact on ridge wear is striation width > striation interval > striation length. Research limitations/implications Because of the specified tool, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further. Originality/value It is shown that the wear resistance of striated CWR tool is better than that of smooth tool. The information may help CWR manufactures to design and produce tools with less wear.

Mental Well Being

Purpose Carers of people with mental health problems present with high levels of burden, poor mental well-being and feelings of disempowerment by mental health services. The purpose of this paper is to establish whether providing a psychoeducation skill programme for carers would lead to an improvement of mental well-being, reduce the levels of burden that carers sometimes feel while caring for someone with mental illness and also to increase empowerment. This paper provides a service evaluation study of an innovative carer-led psychoeducational intervention that was undertaken. Design/methodology/approach This programme was initiated and led by a carer who had experienced a lack of service provision to support carers and families in understanding and caring for a relative with severe and enduring mental health diagnoses. A model of co-production was adopted with the carer who led this initiative working closely with an occupational therapist and consultant psychologist in its development and delivery. Data were collected to measure the impact of the training at five different time points. The measures employed to measure outcomes were the Warwick-Edinburgh Mental Well-being Scale, the Burden Assessment Scale and Family Empowerment Scale. Findings Results indicated improved well-being, reduced burden and increased family empowerment in carers who completed this peer-led carer initiative psychoeducational programme. Research limitations/implications This service evaluation study was conducted in a single site and in the site in which it was developed. The carer consultant who led this evaluation and development of the intervention was also the peer worker who delivered the interventions. Hence, the authors are unable to ascertain if the results reported are unique to the individual peer worker. The transferability of this programme and generalisability of the result should therefore be treated with caution and further replication of this model and research is required. This would be beneficial to be conducted in an alternative site from where it was developed, delivered by different facilitators and include a control group. Practical implications The evidence from this study indicates that carers are able and willing to attend a group psychoeducational programme. A high number of referrals to the programme in a relatively short timeframe indicates that there is significant demand for such a service. The implementation of the programme is relatively straightforward. The key challenges for practical implementation are to have the right carer to lead and deliver the programme and the right support system in place for them (financial and supervision). Co-production also is not without challenges, the peer worker and occupational staff need to ensure that mutually valued and respected working relationship should develop. Originality/value This is the first evaluation of the impact of a carer-led psychoeducation intervention for carers of people with mental health difficulties in secondary mental health services.

The Impact

Despite of the popularity of interactive movie trailers, rigorous research on one of the most apparent features of these interfaces – the level of user control – has been scarce. This study explored the effects of user control on users’ immersion and enjoyment of the movie trailers, moderated by the content type. We conducted a 2 (high user control versus low user control) × 2 (drama film trailer versus documentary film trailer) mixed-design factorial experiment. The results showed that the level of user control over movie trailer interfaces decreased users’ immersion when the trailer had an element of traditional story structure, such as a drama film trailer. Participants in the high user control condition answered that they were less fascinated with, absorbed in, focused on, mentally involved with, and emotionally affected by the movie trailer than participants in the low user control condition only with the drama movie trailer. The negative effects of user control on the level of immersion for the drama trailer translated into users’ enjoyment. The impact of user control over interfaces on immersion and enjoyment varies depending on the nature of the media content, which suggests a possible trade-off between the level of user control and entertainment outcomes.

Purpose The purpose of this paper is to explore the experiences of working women in a male-dominated country (Morocco) and unveil the unique challenges and everyday gender-bias they face, the psychological impact of the perceived gender-bias and, finally, identify a variety of coping strategies or combatting mechanisms affecting their motivation and retention in the workplace. Design/methodology/approach Empirical evidence was obtained using a qualitative research method. The Critical Incident Technique (CIT) was used to collect incidents recalled by women in the select institution reflecting their perceptions of their managers’ ineffective behaviors towards them and the impact of these behaviors. The critical incidents were inductively coded, and behavioral statements were derived from the coded data. Findings The qualitative data analysis led them to structure the data according to two theme clusters: The perceived gender-bias behaviors (Covert and evident personal and organizational behaviors) and Psychological impacts resulting from the perceived bias. These behavioral practices included abusive behaviors, unfair treatment, bias and lack of recognition. The psychological impact elements involved decreased productivity, depression, anxiety and low self-esteem. Practical implications Understanding these experiences can facilitate the identification of strategies geared towards the retention of women in the workforce, and Moroccan organizations can develop and implement strategies and policies that are geared towards eliminating gender-bias in the workplace and to retaining and motivating women who remain ambitious to work in male-dominated environments and cultures. Originality/value This paper provides evidence that sufficient organizational mechanisms to support women in male-dominated environments are still unavailable, leaving them to find the proper coping mechanisms to persevere and resist.

The Impact

Purpose This paper aims to investigate the impact of three critical dimensions of supply chain resilience, supply chain preparedness, supply chain alertness and supply chain agility, all aimed at increasing a firm’s financial outcomes. In a turbulent environment, firms require resilience in their supply chains to prepare for potential changes, detect changes and respond to actual changes, thus providing superior value. Design/methodology/approach Using survey data from 77 firms, this study develops scales for preparedness, alertness and agility. It then tests their hypothesized relationships with a firm’s financial performance. Findings The results reveal that the three dimensions of supply chain resilience (i.e. preparedness, alertness and agility) significantly impact a firm’s financial performance. It is also found that supply chain preparedness, as a proactive resilience capability, has a greater influence on a firm’s financial performance than the reactive capabilities including alertness and agility, suggesting that firms should pay more attention to proactive approaches for building supply chain resilience. Originality/value First, this study develops a comparatively comprehensive definition for supply chain resilience and explores its dimensionality. Second, this study provides empirically validated instruments for the dimensions of supply chain resilience. Third, this study is one of the first to provide empirical evidence for direct impact of supply chain resilience dimensions on a firm’s financial performance.

PurposeThis study explores how the firm’s proprietary information has an impact on the bank loan contracts. It explains the propensity of using the competitive bid option (CBO) in the syndicate loans to solicit the best bid for innovative firms and how it changes based on industry competition and the degree of innovations. This research also examines how the interstate banking deregulation (Interstate Banking and Branching Efficiency Act) in 1994 affected the private loan contracts for innovative borrowers.Design/methodology/approachThe study uses various econometric analyses. First, it uses the propensity score matching analysis to see the impact of patents on pricing terms. Second, it uses the two-stage least square (2SLS) analysis by implementing the litigation and non-NYSE variables. Finally, it studies the impact of the policy change of the Interstate Banking and Branching Efficiency Act of 1994 on the bank loan contracts.FindingsFirms with more proprietary information pays more annual facility fees but less other fees. The patents are the primary determinants of the usage of CBO in the syndicate loans to solicit the best bid. While innovative firms can have better contract conditions by the CBO, firms with more proprietary information will less likely to use the CBO option to minimize the leakage of private information and the severe monitoring from the banks. Finally, more proprietary information lowered the loan spread for firms dependent on the external capital after the interstate banking deregulation.Originality/valueThe findings of this research will help senior executives with responsibility for financing their innovative projects. In addition, these findings should prove helpful for the lawmakers to boost economies.

PurposeThis paper analyses the interrelationships between emotions, the cognitive information cues of online reviews and intention to follow the advice obtained from digital platforms, paying special attention to the moderating effect of the sequencing of review valence.Design/methodology/approachThe data were collected from 830 Spanish Tripadvisor users. In a two-step approach, a measurement model was estimated and a structural model analysed to test the proposed hypotheses. SmartPLS 3.0 software was used. The moderating effect of sequencing of reviews is tested.FindingsThe data analysis showed a bias effect of review sequence on the impact of online information cues and emotions on intention to follow advice obtained from Tripadvisor. When the online reviews of a restaurant begin with positive commentaries, their perceived persuasiveness is a stronger driver of the pleasure and arousal elicited by online reviews than when they begin with negative reviews. On the other hand, the perceived helpfulness of online reviews only triggers arousal when the user reads negative, followed by positive, comments. The impact of pleasure on intention to follow the advice provided in an online travel community is higher with positive-negative than with negative-positive sequences.Originality/valueWhile researchers have demonstrated the benefits of customer reviews on company sales, a largely uninvestigated issue is the interplay between emotions and cognitive information cues in the processing of online reviews. This is one of the first studies to examine the moderating effect of conflicting reviews on the impact of emotions and cognitive information cues on consumer intention to follow the advice obtained from digital services.
