Comparison of the holiday tourism constraints of mono- and bicultural people
Authors: Davras Özgür , Caber Meltem , Crawford Duane
Published: May 2019

Purpose

This study aims to investigate whether the three-dimensional leisure constraints model which is adapted to holiday tourism shows the same structure for mono- and bicultural people and perceptions of these groups differ from each other.

Design/methodology/approach

Separate surveys are conducted on Turkish people who are resident in Turkey, representing the mono-cultural structure, and Turkish people who live in Germany, representing the bicultural structure. The model is tested by factor analysis for each group, whereas perception differences on holiday tourism constraints are compared with t-tests.

Findings

The analysis results showed that the factorial structure of the leisure constraints model is not the same in the holiday tourism context. Hence, new constraints dimensions were obtained in each case. A comparison of the holiday tourism constraints also showed that the perceptions of the mono- and bicultural people were significantly different from each other.

Originality/value

The current study has contributions to the literature in terms of examining the holiday tourism constraints by using the adapted version of the leisure constraints model. Moreover, targeting Turkish people who live in Turkey and Germany, as the study samples, indicates a unique representation of mono- and bicultural structures.
Indicators to assess organizational resilience – a review of empirical literature
Authors: Rahi Khalil
Published: May 2019

Purpose

This paper aims to explore the empirical literature on organizational resilience. The goal consists of identifying and understanding the indicators used to evaluate organizational resilience and instigating the development of indicators to assess resilience in other areas, such as project management and critical infrastructure.

Design/methodology/approach

A review of recent empirical studies is conducted to collect information on the indicators used to assess organizational resilience.

Findings

A range of interrelated indicators aiming to measure organizational resilience in two dimensions is shown in this literature review: awareness and adaptive capacity. Awareness is the ability of an organization to assess its environment and interpret the changes in its surroundings, both now and in the future, to be proactive and better manage possible disruptive events. On the other hand, adaptive capacity is the organization’s capacity to transform its structure, processes, culture, etc. for recovering once faced with a disruptive event. Awareness forms the main base of the organization’s adaptive capacity.

Originality/value

Organizational resilience contributes to the safe development of the built environment. This concept helps organizations to cope with disruptions. However, little research has been conducted on the indicators to assess organizational resilience, in different fields. Moreover, these indicators’ credibility is based on empirical studies.
Exploring clinical communication in a teaching hospital in Ghana
Authors: Abor Patience Aseweh
Published: May 2019

Purpose

The purpose of this paper is to investigate the clinical communication using Tamale Teaching Hospital as a case.

Design/methodology/approach

The paper is based on the Reassure, Explain, Listen, Answer, Take Action and Express Appreciation (RELATE) model and the Four Habits models of Clinical Communication.

Findings

The results of the study indicate that leadership conducted staff meetings with some of the components of the RELATE model. These include staff meetings, employee rounding and communication/notice boards. The results of the study also suggest that much as some parts of the Four Habits model was used in provider–patient communication, certain aspects of the model were absent. The study identified some communication challenges including poor dissemination, lack of unity among some health workers, poor attendance in meetings and, with respect to patients, language barrier, patients’ reluctance to disclose their actual health problems to health providers, lack of privacy and lack of a friendly environment.

Practical implications

Providers, especially physicians, should be given training on the local languages in areas where they perform their services. Health service providers should receive as part of their learning in-depth training on the Four Habits model of Clinical Communication, especially the Medical Officers.

Originality/value

It is imperative to embrace evidence-based practices/models aimed at securing proper communication in all hospitals but most especially teaching hospitals.
Team-member exchange and innovative work behaviour
Authors: Ghosh Vinit , Bharadwaja Manaswita , Yadav Sresha , Kabra Gaurav
Published: May 2019

Purpose

In the context of team's influence on its members, this paper aims to investigate the effects of team-member exchange (TMX) on members' innovative work behaviour (IWB). The current study presents a moderated mediation model and examines the mechanisms and conditions involved in TMX-IWB relationship.

Design/methodology/approach

A quantitative research methodology was adopted where 156 engineering and management students (grouped into 33 teams) were given a task in the form of an assignment to be completed in three weeks’ timeframe. Post task, perceptions about TMX and IWB of members were captured using a questionnaire and the innovative output of each team was assessed using multi-rater technique.

Findings

Psychological empowerment fully mediates TMX’s effect on team member's IWB. Furthermore, the results indicate that creative self-efficacy moderates the mediated path from TMX to IWB via psychological empowerment. The mediating effect of psychological empowerment is stronger when creative self-efficacy of a team member is higher. Furthermore, the relation between group-level innovative behaviour and the team's innovative output has been established.

Originality/value

The current research has contributed to the limited literature on team performance and management. This paper has uniquely investigated psychological empowerment in the context of TMX and IWB. The paper has encapsulated the theoretical and practical underpinnings of the mediated effect of psychological empowerment on team members' innovation-oriented behaviour.
Quality of prison life, violence and mental health in Dubrava prison
Authors: Skar Mette , Lokdam Nicoline , Liebling Alison , Muriqi Alban , Haliti Ditor , Rushiti Feride , Modvig Jens
Published: May 2019

Purpose

The purpose of this paper is to explore the association between the quality of prison life and mental health among prisoners and the occurrence of violence.

Design/methodology/approach

In total, 203 prisoners from Dubrava Correctional Center in Kosovo participated. Data on background characteristics of the prisoners, quality of prison life, mental health symptoms and exposure to physical, psychological and sexual violence were collected through interviewer-administered questionnaires. Data were analyzed using general linear models (GLM) and manual backwards model search with step-wise exclusion.

Findings

The GLM analysis showed a significant negative association between anxiety symptom load (−1.4), physical violence (−1.5) and psychological violence (−1.9), and quality of prison life. Furthermore, it appeared that prisoners rating of quality of life (QoL) increased with time among prisoners not exposed to violence, while this was not seen among prisoners exposed to violence. Finally, there was an inverse association between the dimensions of respect, fairness, humanity and good staff/prisoner relations, and the proportion of prisoners exposed to violence.

Originality/value

An environment with higher levels of respect, fairness, humanity and good relations between staff and prisoners was associated with lower levels of violence. Hence, a prison that focuses on promoting QoL and good mental health among prisoners will show lower levels of violence, thereby making the prison a more tolerable place for the prisoners and a better working environment for prison staff.
Evaluating quantity surveying firms’ performance
Authors: Osunsanwo Hannah Feyisayo , Dada Joshua Oluwasuji
Published: May 2019

Purpose

The purpose of this paper is to evaluate the performance of quantity surveying firms (QSFs) using the balanced scorecard (BSC) technique.

Design/methodology/approach

Based on a survey of 37 QSFs in Lagos State, Nigeria, the paper empirically assessed the performance of QSFs using the BSC technique. The targeted respondents were principal partners and quantity surveyor employees in the selected QSFs and relevant construction stakeholders, including clients, architects, builders and structural engineers, who usually have business relation with QSFs.

Findings

The findings of this paper revealed high levels of performance in non-financial measures of the BSC dimensions while low level performance is recorded in financial measure.

Practical implications

The exemplified performance measures allow QSFs’ managers to set their own priorities and to seek out improvements along the BSC dimensions of performance measure. The high performance recorded in non-financial perspectives needs to be sustained while a lot of efforts need to be put in place in order to improve the financial performance, thereby sustaining their viability.

Originality/value

This paper contributes methodologically through the application of a balance and all-encompassing principles in assessing performance. The use of this measure enables QSFs to structure a balance assessment of their operation, to identify their strengths and weakness, and to target areas for improvement in order to reach their desired business goals.
The contribution of social media to project management
Authors: Kanagarajoo Muralitheran V. , Fulford Richard , Standing Craig
Published: May 2019

Purpose

The purpose of this paper is to determine the social media (SM) tools that are the most prevalent for project management activities, ascertain the areas of project management that are most benefited by SM, elucidate enablers and inhibitors to adoption of SM and identify the implications for virtual teams.

Design/methodology/approach

A Delphi study was used to explore why and how SM is being utilized in projects. In total, 32 participants contributed to three rounds of Delphi study, comprising two rounds of questionnaire followed by confirmatory interviews. The vulnerabilities and difficulties associated with the use of SM were examined by qualitative interviews.

Findings

Information sharing SM tools, such as YouTube, Dropbox, SlideShare, flickr, CrowdStorm and Instagram, are the most advantageous to project management. However, the tools utilized differ at different stages of the project lifecycle. The major benefit of SM is that it enables project teams to communicate efficiently and positively affects virtual team dynamics. Adoption can be inhibited by the absence of infrastructure in rural areas and differing preferences for SM tools in global regions. There is also a perceived lack of maturity of policies and procedures to govern SM adoption and use.

Research limitations/implications

The research was conducted based on the Project Management Body of Knowledge version 5 project management processes.

Practical implications

The findings will enable practitioners to select SM tools that are suitable for project activities and forewarn about potential shortfalls. The findings also facilitate a qualitative analysis of SM attributes and their effect on project management.

Social implications

Project practitioners can use the findings to adopt SM for their project management.

Originality/value

This study extends the literature concerning the use of SM for project management, provides a foundation for future research and may present as a useful guide for the adoption of relevant SM tools.
A process for successfully implementing BPR projects
Authors: Fasna M.F.F. , Gunatilake Sachie
Published: May 2019

Purpose

The purpose of this paper is to analyse the business process reengineering (BPR) implementation process adopted by organisations grounded in the actual project-level realities. The findings are used to propose a BPR implementation process that can be adopted by organisations to effectively reengineer their processes.

Design/methodology/approach

A thorough literature review was used to first develop a conceptual BPR implementation process comprising three key phases and five steps. Then, four case studies were conducted in organisations that have successfully undertaken BPR projects to explore the actual project-level implementation processes. Semi-structured interviews were carried out with respondents who have been actively involved in the different steps of the BPR implementation processes to collect data within the selected organisations.

Findings

Altogether 30 activities which are to be carried out throughout the BPR implementation process were identified. Findings disclosed that the minor differences in the activities being performed throughout the BPR implementation process are due to the lack of homogenous characteristics, i.e. type of the process reengineered, form of reengineering and approach for implementing BPR projects.

Originality/value

This paper puts forward a comprehensive view on the BPR implementation process including the key phases, steps and the sequence of activities to be followed. In doing so, the paper addresses a clear gap in literature that calls for a comprehensive model to assist during the BPR implementation to achieve the desired results.
Support for women’s rights and feminist self-identification as antecedents of attitude toward femvertising
Authors: Sternadori Miglena , Abitbol Alan
Published: May 2019

Purpose

Existing research demonstrates that consumers prefer advertising that aligns with their values and beliefs but can also be distrustful of claims of corporate social responsibility. The purpose of this paper is to explore consumers’ perceptions of femvertising in relation to their worldview. Femvertising is defined as “advertising that employs pro-female talent, messages, and imagery to empower women and girls” (Skey, 2015).

Design/methodology/approach

A survey of US adults (n = 419) was used to investigate attitudes toward femvertising as they relate to gender, age, support for women’s rights, feminist self-identification, political affiliation and trust in advertising.

Findings

Structural equation modeling revealed several antecedents and consequences of attitude toward femvertising. The findings suggest that women’s rights supporters and self-identifying feminists seem highly receptive of femvertising.

Originality/value

Taken together, the findings clarify how femvertising can be an effective strategy for marketers and how it fits within the current advertising literature.
Effects of personal dispositions, familiarity and consumption situation on Western brands’ packaging
Authors: Khan Huda
Published: May 2019

Purpose

Supermarket scans in the contextual non-Western markets (Pakistan and China) revealed that the majority Western consumer products are available in both global (English) and the vernacular language (Urdu, Chinese) packaging. The availability of two different packaging raises a question – which is more effective and under what situation. This study aims to address this question by investigating the roles of an internal-oriented disposition (concern for quality) and an external-oriented disposition (social consciousness) on packaging choice, under different consumption situations (conspicuous versus inconspicuous). The conceptual model tested concern for quality as a mediator on the influence of social consciousness on packaging choice, under the moderating effects of conspicuous versus inconspicuous consumption situation.

Design/methodology/approach

Two in-store choice experiments were conducted in Pakistan and China. Shoppers who agreed to participate were first primed to either of the two conditions (conspicuous and inconspicuous). They were then shown two packaging types (global versus local language) on store shelves and asked to pick the preferred packaging. Finally, the participants completed a paper-based questionnaire containing the scale items and demographics variables.

Findings

Participants with high social consciousness preferred the global (English) packaging. The interaction effect of social consciousness and consumption situation moderated the choice. Concern for quality mediated the influence of social consciousness on global packaging preference.

Originality/value

This study extends the research into packaging by considering the mediating relationship and conceptualisation between external-oriented personal antecedent (social consciousness) and internal-oriented disposition (concern for quality), under different consumption (conspicuous versus inconspicuous) situation. The findings will inform brand managers’ packaging strategies in non-Western markets.
A phenomenological approach to the collaborative consumer
Authors: Barbosa Belem , Fonseca Isabel
Published: May 2019

Purpose

Collaborative consumption emerges from social practices such as sharing, lending and gifting. It is becoming more common among consumers, boosted by the internet, which facilitates the collaboration process with both strong and weak ties. This paper aims to examine collaborative consumer experience, delving into the factors that contribute to the adoption and the perceived benefits of this alternative form of consumption.

Design/methodology/approach

A total of 12 phenomenological interviews were conducted o explore the theme from an individual perspective, attested by the consumers’ narratives and experiences.

Findings

The results highlight collaborative consumption as being influenced by family practices, social relations and the current economic scenario. Also, noteworthy is the evidence that collaborative consumption enables consumers to select from a more diversified portfolio of products and services, especially the ones featured by the internet and social media. Consumers perceive financial, emotional, social, environmental and increased consumption benefits, depending on their practices of collaborative consumption, and also on their role as providers, consumers or exchangers.

Originality/value

Through the phenomenological approach, based on individual reports of experiences related to collaborative consumption, it was possible to highlight some aspects relevant to better understanding the behavior of collaborative consumers.
A well-tailored centrality measure for evaluating patents and their citations
Authors: Donato Claudia , Lo Giudice Paolo , Marretta Roberta , Ursino Domenico , Virgili Luca
Published: May 2019

Purpose

The development of innovations in all the research and development (R&D) fields is leading to a huge increase of patent data. Therefore, it is reasonable to foresee that, in the next future, Big Data-centered techniques will be compulsory to fully exploit the potential of this kind of data. In this context, network analysis-based approaches are extremely promising. The purpose of this paper is to provide a contribution to this setting. In fact, the authors propose a well-tailored centrality measure for evaluating patents and their citations.

Design/methodology/approach

The authors preliminarily introduce a suitable support directed network representing patents and their citations. After this, the authors present the centrality measures, namely, “Naive Patent Degree” and “Refined Patent Degree.’” Then, the authors show why they are well tailored to capture the specificities of the patent scenario and why classical centrality measure fails to fully reach this purpose.

Findings

The authors present three possible applications of the measures, namely: the computation of a patent “scope” allowing the evaluation of the width and the strength of the influence of a patent on a given R&D field; the computation of a patent lifecycle; and the detection of the so-called “power patents,” i.e., the most relevant patents, and the investigation of the importance, for a patent, to be cited by a power patent.

Originality/value

None of the approaches proposing the application of centrality measures to patent citation networks consider the main peculiarity of this scenario, i.e., that, if a patent pi cites a patent pj, then the value of pi decreases. So, differently from classical scientific paper citation scenario, in this one performing a citation has a cost for the citing entity. This fact is not considered by all the approaches conceived to investigate paper citations. Nevertheless, this feature represents the core of patent citation scenario. The approach has been explicitly conceived to capture this feature.
From fact to fantasy
Authors: Kjellman Ulrika
Published: May 2019

Purpose

The purpose of this paper is to examine the characteristics and functions of images in scientific practices and how scientific images differ to other types of representation (e.g. textual, numerical or artistic images). To address these questions, the study looks into the illustration practice of the Swedish researcher Gaston Backman, who wrote several books on the origin of the human species, human anatomy, physical anthropology and race biology in the beginning of the twentieth century.

Design/methodology/approach

A comparative and functional analytical method is applied to show how the images act in his writings and how rhetorical and technical circumstances affect the way the images communicate and document scientific facts and ideas. Theoretically, the study relates to ideas suggesting: images to be serious partakers and vehicles of representation in the practice of science; and the need for images to be schematic and more abstract in comparison to an iconic image in order to work in this practice.

Findings

The findings of this study show that Backman used both schematic and iconic images in his research writings, and that these different image expressions had different functions: where the former was based on facts and had an informative and scientific function, the latter was based on fantasy/myth and used to promote ideological values and ideas.

Originality/value

This study stresses the importance of images in the practice of science, i.e. how images alongside verbal or numerical expressions act as important information and knowledge carriers in the work of science. Even though images intermingle with verbal and numerical expression, they also have a unique and specific, a role that needs to be taken seriously and investigated further in the realm of information studies and document studies. The authors also need to be aware that images can have different functions in the scientific practice, and are not always there to carry scientific facts or ideas, but ideologies and fantasies.
Adding or destroying value? User experiences of tourism self-service technologies
Authors: Kelly Petranka , Lawlor Jennifer
Published: May 2019

Purpose

The global tourism industry is continuing to experience a change from high-touch to high-tech with the increasing implementation of self-service technologies (SSTs) such as hotel reservation websites, kiosk technologies at airports and smartphone applications. SSTs require active customer involvement in the service delivery process and as such, the customer serves as a co-creator of value along with the tourism provider. Although there are benefits to customer involvement in service provision, there is a risk that SST usage may also detract value from the service experience. Therefore, the purpose of this paper is to explore customer perspectives on their experiences of SST usage in a tourism context, through the theoretical lens of the service–dominant logic framework.

Design/methodology/approach

This interpretivist study employs a two-stage qualitative methodology of short interviews with 133 participants at an international airport, followed by 32 in-depth interviews with SST users in a tourism context.

Findings

Six diverse customer SST experiences are identified and then classified in terms of being either value-creating or value-destroying. The first two experiences accruing from SST usage, namely accomplishment and supportiveness, are deemed to be value-creating, while the experiences of lack of control, manipulation, concern about discrimination and social tension are deemed to be value-destroying.

Originality/value

The study responds to a gap in the literature regarding the concept and nature of customer value co-creation pertaining to the use of SSTs in a tourism context. The research findings indicate that value is not only created but may also be destroyed in the SST encounter. The study also illustrates that SST usage may have a strong social element in terms of the presence and role of other customers and employees. This challenges the consensus in the literature that SST usage reduces or removes human interaction.
Clinical depression moderates effects of animal-assisted stress prevention program on college students’ emotion
Authors: Pendry Patricia , Vandagriff Jaymie L. , Carr Alexa Marie
Published: May 2019

Purpose

The purpose of this paper is to examine whether clinical levels of depression moderated university students’ momentary emotional states (e.g. feeling content, anxious, irritable and depressed) in response to conditions commonly experienced during universal, college-based Animal Visitation Programs (AVPs).

Design/methodology/approach

During a real-life efficacy trial, students (N = 192) were randomly assigned to three common AVP conditions: a hands-on condition in which participants could freely pet cats and dogs in small groups, an observation condition in which participants observed students in the hands-on condition while awaiting one’s turn and a control condition in which participants viewed images of the same animals while refraining from socializing with peers. Using a checklist, students reported their momentary emotional states (e.g. feeling content, anxious, irritable and depressed) before and after the 10-min intervention.

Findings

Multivariate regression analyses showed that clinically depressed students reported significantly higher levels of momentary negative emotion including irritability, depression and anxiety after waiting in line compared to non-depressed students, suggesting that clinical depression may moderate potential stress-relieving effects of universal college-based AVPs depending on implementation practices.

Originality/value

This is the first study to examine the causal impact of a common yet unstudied feature of college-based AVPs aimed at reducing general college student stress. Results support the utility of targeted approaches for students presenting clinical levels of depression.
The experience of occupational psychosocial stress among librarians in three African countries
Authors: Agyei Dominic Dankwah , Aryeetey Faustina , Obuezie Adaora Chigozie , Nkonyeni Sixolile
Published: May 2019

Purpose

The purpose of this paper is to focus on describing the experience of occupational psychosocial stress among librarians in Ghana, Nigeria and South Africa. It further seeks to identify the various psychosocial stress components and how they interact to determine the stress level of librarians.

Design/methodology/approach

Using the Effort-Reward Imbalance scale, this descriptive study employed a web-based data collection tool (Google Form) to design and solicit data from respondents. Convenient sampling technique was used to employ 153 librarians from Ghana, Nigeria and South Africa with at least a diploma in any library-related programme, who work in either academic, public or special libraries.

Findings

This study established the prevalence of occupational psychosocial stress among librarians from Ghana, Nigeria and South Africa. It was realised that gender, country of residence of respondents, age, work experience, workers with children under 13 years of age and work roles were the main factors that influenced the occupational stress among the respondents.

Research limitations/implications

The response rate for this study was low. As a result, undertaking any inferential statistics to explain relationships was not possible.

Originality/value

The value of this study lies in the depth of narrative data collected and the insight it affords with regards to contemporary work within libraries in Africa and beyond. The results presented may provide both a starting point for further discussion and may also promote an increased openness about issues of employee safety in the library environment.

Published: May 2019

Purpose

The purpose of this paper is a micro-level examination of the role and function of cooperative research centers (CRCs) in entrepreneurial universities from a principal investigator (PI) perspective.

Design/methodology/approach

This study uses a qualitative research design and is based on 38 semi-structured interviews with PIs who are publicly funded at the Centre for Research in Medical Devices (CÚRAM) based in Ireland. CÚRAM has a multiple mission focus of supporting scientific excellence, industry engagement, educational and public engagement that supports the Irish medical device sector.

Findings

The findings reveal that CRCs’ role and function at the micro level constitute a necessary and functional organization architecture that supports PIs who are required to meet multiple scientific, commercialization, educational and public engagement objectives. Specifically, from the micro-level PI perspective, the role and function of CRCs focus on research quality enhancement, brokerage, networks and collaborations, addressing research impact and resource enhancement and appropriation.

Practical implications

This research emphasizes the importance and necessity for the creation of CRCs as part of the entrepreneurial architecture of entrepreneurial universities that provides the necessary appropriate local environmental conditions and enhanced supports to enable micro-level actors to fulfill multiple mission objectives with respect to research excellence, industry, educational and public engagement and impact.

Originality/value

This study contributes to the limited literature on new institutional configurations that support entrepreneurship and addresses recent calls for further research. In taking a micro-level focus, the authors identify the role and function of CRCs from a PI perspective in an entrepreneurial university setting.
A systematic review of flipped classroom empirical evidence from different fields: what are the gaps and future trends?
Authors: Zainuddin Zamzami , Haruna Hussein , Li Xiuhan , Zhang Yin , Chu Samuel Kai Wah
Published: May 2019

Purpose

Despite the enhanced popularity of flipped classroom research, there is a lack of empirical evidence reported about the different impacts revealed by the implementation of this concept. Therefore, to respond to this issue, this study aims to review and analyze the trends and contents of flipped classroom research based on 48 studies recently published in 2017 and 2018. The analysis was based on flipped classroom impacts from various fields.

Design/methodology/approach

A systematic literature review and content analysis were used as a methodology to investigate positive impacts and challenges of flipped classroom implementation.

Findings

The results of the analysis were interpreted using descriptive analysis. Analysis of the impact revealed that the flipped classroom yielded positive impacts on students’ learning activities such as academic performance, learning motivation and/or engagement, social interaction and self-directed learning skills. Meanwhile, the most significant challenges encountered by the instructors is a lack of students’ motivation to watch the pre-recorded video lectures or to study the contents outside of the class time.

Practical implications

Several issues in this discussion become implications that can be taken into consideration for future research. The findings suggest that the flipped classroom concept might be effective in promoting the twenty-first century learning skills.

Originality/value

While highlighting the limitations of an ineffective flipped classroom implementation, this study proposes further recommendations for future research.

Authors: Ancelin-Bourguignon Annick
Published: May 2019

Purpose

Drawing on educational science research and concepts, this paper aims to organize and analyze prior accounting literature on the integration of research into teaching and provides evidence for the relevance of integrating research into constructivist management accounting teaching.

Design/methodology/approach

Evidence shall be drawn from the autoethnographic account of a case study, namely, an MiM course in a French business school.

Findings

The presentation of qualitative research plays a priming role in collective debates where knowledge is co-produced by the group of students.

Research limitations/implications

The analysis opens up many avenues for future research on constructivist accounting teaching (e.g. teachers’ profiles, cross-cultural comparison) and its consequences.

Practical implications

The case provides examples of how, in practice and beyond general principles, the constructivist teacher adapts to his/her audience and their educational heritage. It also invites a holistic consideration of teaching arrangements, the relationships between their elements and their collective impact on learning.

Originality/value

The case study, the analysis of which draws on educational science frameworks and concepts, provides an in-depth account of research integration into constructivist accounting teaching.
Fabrication of 3D microfluidic structure with direct selective laser baking of PDMS
Authors: Riahi Mohammadreza , Karimi Fatemeh , Ghaffari Atefeh
Published: May 2019

Purpose

The purpose of this paper is to present three-dimensional (3D) printing of structures with a new method called selective laser baking (SLB) of Poly Dimethyl Siloxane (PDMS).

Design/methodology/approach

A 3D model is designed on the computer. PDMS Base is mixed with its hardener and poured into a container. Before it is hardened which normally occures after several hours, a CO2 laser selectively exposes different areas on the surface of the PDMS mixture according to the pattern of a slice of a 3D model designed on the computer. Because of the thermal effect of the CO2 laser, once exposed, PDMS heats up and hardens, producing a cured layer of PDMS which is attached to a base. The base with the cured layer is lowered in the container for a short distance and a layer of new uncured PDMS is spread over the previous layer. The laser exposes new areas again and hardens them. This process is repeated until the whole structure is fabricated.

Findings

The parameters involved in the baking process are investigated and the relation between temperature, mixing portion and laser irradiance on the curing time and layer thickness are investigated.

Originality/value

This fabrication technique is a unique fabrication method that helps to 3D print with two base polymers which their polymerization can be boosted by heat. This 3D printing method has not been presented earlier.
Metal bellow hydroforming using additive manufactured die: a case study
Authors: R. Prithvirajan , M. Sugavaneswaran , N. Sathishkumar , G. Arumaikkannu
Published: May 2019

Purpose

Custom-designed metal bellows require alternate ways to produce the die to shorten lead time. The purpose of this study is to explore the possibility of using Additive Manufactured (AM) polymer die as direct rapid tool (RT) for metal bellow hydroforming.

Design/methodology/approach

Finite element analysis (FEA) was used to simulate bellow forming and to evaluate the compatibility of AM die. Fused deposition modelling (FDM) technique is used to fabricate die with Acrylonitrile Butadiene Styrene (ABS) material. To validate, the width of the metal bellow convolutions obtained from the FEA simulation is compared with convolution formed during the experiment.

Findings

FDM-made die can be used for a short production run of bellow hydroforming. FEA simulation shows that stress developed in some regions of die is less and these regions have potential for material reduction. Use of RT for this particular application is limited by the die material, forming pressure, width, convolution span and material of bellow. This supports the importance of FEA validation of RT before fabrication to evaluate and redesign die for the successful outcome of the tool.

Research limitations/implications

The given methodology may be followed to design a RT with minimum material consumption for bellow forming application. Whenever there is a change in bellow design or the die material, simulation has to be done to evaluate the capability of the die. As this study was focused on a short production run for manufacturing one or few bellows, the die life is not a significant factor.

Originality/value

This paper demonstrates about rapid tooling for metal bellow manufacturing using FDM technique for low volume production. Further, FEA is used to identify low stress regions and redesign the die for material reduction before die manufacturing. AM die can be used for developing customized metal bellow for applications such as defense, aerospace, automobiles, etc.
Application of FDM technology to reduce aerodynamic drag
Authors: Sanchez Ramirez Alberto , Islán Marcos Manuel Enrique , Blaya Haro Fernando , D’Amato Roberto , Sant Rodolfo , Porras José
Published: May 2019

Purpose

The purpose of this paper is to analyze the aerodynamic improvements obtained in a wing section with a NACA 0018 airfoil manufactured using the fused deposition modeling (FDM) technique with regard to a smooth surface made by milling. The creation of micro-riblets on the surface of the airfoil, due to the deposition of the material layer by layer, improves the general aerodynamic performance of the parts, provided that the riblets are parallel to the flow line. The incidence of the thickness of the thread deposited in each layer – to be the variable on which the geometry of the riblets is based – was studied.

Design/methodology/approach

The wing section was designed using 3D software. Three different models were designed by rapid prototyping, using additive and subtractive manufacturing. Two of the profiles were manufactured using FDM varying the thickness of the layer to be able to compare the aerodynamic improvements. The third model was manufactured using a subtractive rapid prototyping machine generating a smooth surface profile. These three models were tested inside the wind tunnel to be able to quantify the aerodynamic efficiency according to the geometry and the riblets size.

Findings

The manufacture of an aerodynamic profile using FDM provides, in addition to the lightness and the ability to design parts with complex geometries, an improvement in the aerodynamic efficiency of 10 per cent compared with profiles with a smooth surface.

Practical implications

With the aerodynamic advantage gained through the use of FDM positions, the additive manufacturing serves as an excellent alternative for the manufacture of lightweight aerodynamic parts, with low structural loading and with low Reynolds number (∼5·105). This technological advantage would be applied to the UAV (unmanned aerial vehicle) industry.

Originality/value

The study carried out in this article demonstrates that the use of FDM as a manufacture process of end-used parts that are subject to movement generates an additional advantage that had not been considered. The additive manufacturing allows us to directly manufacture riblets by creating the necessary surface so as to reduce the aerodynamic drag.
Study of thermal and rheological properties of PLA loaded with carbon and halloysite nanotubes for additive manufacturing
Authors: Cobos Christian Mauricio , Garzón Luis , López Martinez Juan , Fenollar Octavio , Ferrandiz Santiago
Published: May 2019

Purpose

This paper aims to propose using polylactic acid (PLA) as an alternative to nanocomposites in additive manufacturing processes in fusion deposition modelling (FDM) systems and describe its thermal and rheological conditions with multi-wall carbon nanotube (PLA/MWCNT) and halloysite nanotube (PLA/HNT) composites for possible applications in additive manufacturing processes.

Design/methodology/approach

PLA/MWCNTs and PLA/HNTs were obtained through fusion in a co-rotating twin-screw extruder. PLA was mixed with different percentages of MWCNTs and HNTs at concentrations of 0.5 Wt.%, 0.75 Wt.% and 1 Wt.%. Differential scanning calorimetry (DSC) and capillary rheometry were used to characterise these products, together with an analysis of the melt flow index (MFI).

Findings

The DSC data revealed that the nanocomposites had a glass transition temperature Tg = 65 ± 2°C and a melting temperature Tm = 169 ± 1°C. The crystallisation temperature of PLA/MWCNTs and PLA/HNTs was between 107 ± 2°C and 129°C, respectively. The viscosity data of PLA/MWCNTs and PLA/HNTs obtained by capillary rheometry indicated that the viscosity of the materials is the same as that of neat PLA. These results were confirmed by the higher fluidity index in the MFI analysis.

Originality/value

This paper presents an alternative for the applications of nanocomposites in additive manufacturing processes in FDM systems.
Development of a framework for digital literacy
Authors: Feerrar Julia
Published: May 2019

Purpose

Institutions seeking to develop or expand digital literacy programs face the challenge of navigating varied definitions for digital literacy itself. In answer to this challenge, this paper aims to share a process for developing a shared framework for digital literacy at one institution, including drawing on themes in existing frameworks, soliciting campus feedback and making revisions.

Design/methodology/approach

A draft digital literacy framework was created following the work of an initial library task force. Focus groups were conducted to gather feedback on the framework and to identify areas for future development.

Findings

Focus groups yielded 38 written responses. Feedback themes related to gaps in the framework, structural suggestions and common challenges for learners. Themes in focus group feedback led to several framework revisions, including the addition of Curation as a competency area, the removal of information communication technologies as its own competency area, and the inclusion of Learner rather than Student at the center of the framework.

Practical implications

The approaches described in this case study can be adapted by those looking to create a shared framework or definition for digital literacy on their campuses, as well as to create or revise definitions for other related literacies.

Originality/value

This case study presents an adaptable process for getting started with broad digital literacy initiatives, within the context of existing digital literacy frameworks worldwide.
Food delivery apps in India: wherein lies the success strategy?
Authors: Meenakshi N. , Sinha Anamika
Published: May 2019

Purpose

The purpose of this study is to understand the evolution, current competitive scenario, and future direction for the food-tech business in the Indian market.

Design/methodology/approach

The paper is based on press reports, industry reports, and secondary information about companies based on interviews of CEOs, analysts, industry trend watchers, and academicians.

Findings

The incumbents are competing on the basis of various parameters such as capital infusion (especially, funding), tie-ups with restaurants, customer loyalty, fleet size and management, and management of employees. High growth is driving volumes for all companies, although there is lack of differentiation in offerings. Companies need to build customer loyalty and seek diverse monetization models for profitability in the future.

Research limitations/implications

First, food-tech companies need to identify means of differentiation to gain competitive advantage. Second, customer loyalty is the key to long-term profitability and firms need to identify ways to build it. Promotions and offers cannot build loyalty. Third, firms would need to expand into different types of monetization methods, such as cloud kitchens, B2B food delivery services, to build revenues and profits.

Practical implications

Incumbents and prospective entrants in the food-tech industry need to understand the structure of the industry and the structure of competition to be able to succeed in the long term. They need to understand that promotions cannot be a differentiator and that funding will dry up. Therefore, it is critical to identify means of differentiation to build a loyal customer base.

Social implications

The food-tech industry in India has strong social foundation. More than 50 per cent of the Indian population is below the age of 25, the percentage of working population is increasing in India and so are income levels. In this context, the food-tech business is important as order outs are increasing. This, however, has also led to problems in the workforce for such startups as companies do not want to invest in employee training, safety or work conditions owning to high attrition rate because of the standardized nature of the job.

Originality/value

This paper makes an attempt to assimilate information about the progress of the food-tech industry in India in the last few years. It attempts to identify various factors that decide the nature of competition among incumbent players. It also identifies what factors these incumbents need to bear in mind while looking ahead.
Marketing Scottish social enterprises using a label?
Authors: Bonar Indiana , Karlsson Paula Sonja
Published: May 2019

Purpose

Social enterprises are competitive businesses in the marketplace, yet insubstantial research has investigated how they market their businesses. This paper aims to investigate the impact a social enterprise label – “Buy the Good Stuff” – used in Edinburgh has had on consumer awareness and explore whether a possible national label could be used as a marketing tool by social enterprises in Scotland.

Design/methodology/approach

The study uses a mixed-methods approach, consisting of an online questionnaire with 100 participants and seven semi-structured interviews with representatives of social enterprises involved in the marketing campaign in Edinburgh and representatives of social enterprises who were not involved in the campaign.

Findings

Findings indicate that the label used in Edinburgh has had little impact on increasing consumer awareness of social enterprises. However, a national label has the potential to help social enterprises increase consumer awareness. Yet, successful implementation requires thorough design of the label and broad support for its promotion.

Practical implications

The paper offers insights into the implementation of a national label. Managers of social enterprises and social enterprise networks should consider the findings when adopting marketing activities.

Originality/value

Findings contribute to the sparse literature regarding marketing activities of social enterprises. The paper provides evidence that the broader social enterprise sector and its representatives in Scotland should re-evaluate their position on the introduction of a national label, given that one priority identified for the sector is to create and promote a social enterprise brand which the SE code is not focussed on.
