Abstract

Purpose

The purpose of this paper is to report the development and implementation of a Remotely Accessible Rapid Prototyping Laboratory (RRPL) established at Tennessee Tech University. Instructional materials and best practices are also reported.

Design/methodology/approach

The Rapid Prototyping (RP) Laboratory reported in this paper was established in Fall 2003 and funded by a National Science Foundation (NSF) grant and Tennessee Tech University (TTU) matching funds. Since that time, over a thousand high school students and students studying computer aided design and manufacturing at Tennessee Tech University have practiced with the RP technology. In order to further extend a remote access capability to this current laboratory and let more engineering and technology students learn this technology via online access tools and resources, a new NSF grant was awarded in late 2006. Since that time, the remote RP laboratory development has been practiced by over 50 higher education institutions. In early 2009, another NSF grant was awarded to allow Metro Nashville Public School students to practice in the remote RP laboratory and choose Science, Technology, Engineering and Math (STEM) career academies for their future profession pathways. This paper will report the development and implementation of a remotely accessible laboratory for RP practices. The topics highlighted are the design of the laboratory, its remote delivery implementation to P16 (integrated system of education stretching from early childhood through a four‐year college degree) education systems and web‐based access statistics collected from counting resources.

Findings

Although on‐ground RP systems are commonly practiced by many institutions; such a unique application as reported in this paper was a pioneering effort, since RRPL was used by many educational institutions as part of their curricular practices.

Originality/value

The paper shows how the online accessible laboratory and its instructional materials provide a number of unique features in cost saving and sharing of the RP resources.

Abstract

Purpose

Parallel two-sided assembly lines are usually designed to produce large-sized products such as trucks and buses. In parallel two-sided assembly lines, both left and right sides of the line are used for manufacturing one or more products on two or more assembly lines located parallel to each other. The purpose of this paper is to develop a new mathematical model for the parallel two-sided assembly line balancing problem that helps to evaluate and validate the balancing operations of the machines such as removal of tools and fixtures and reallocating the operators.

Design/methodology/approach

The proposed approach is explained with the help of an example problem. In all, 22 test problems are formed using the benchmark problems P9, P12, P16 and P24. The results obtained are compared among approaches of the task(s) shared, tool(s) shared and both tool(s) and task(s) shared for effect on efficiency as the performance measure. The solution presented here follows the exact solution procedure that is solved by Lingo 16 solver.

Findings

Based on the experiments, line efficiency decreases when only tools are shared and increases when only tasks are shared. Results indicate that by sharing tasks and tools together, better line efficiency is obtained with less cost of tools and fixtures.

Practical implications

According to the industrial aspect, the result of the study can be beneficial for assembly of the products, where tools and tasks are shared between parallel workstations of two or more parallel lines.

Originality/value

According to the author’s best knowledge, this paper is the first to address the tools and tasks sharing between any pair of parallel workstations.

Abstract

Purpose

This study aims to investigate how undergraduate students are influenced by instructors and peers in the ways that they use and think about Wikipedia for academic work. It examines the positive (encouraging the use of Wikipedia) and negative (discouraging the use of Wikipedia) influences of others and how these affect student behavior and attitudes.

Design/methodology/approach

Sixteen undergraduates participated in two meetings each with the principal investigator, each meeting consisting of a structured interview and a brief survey. Recorded interviews were analyzed by the investigator for patterns to compare participants’ responses.

Findings

Participants were more frequently and strongly influenced by instructors than by peers about Wikipedia, and this influence was for the most part perceived to be negative. However, the ways in which student behaviors and attitudes changed in response to this influence varied. Three categories or “influence types” emerged in the ways influence was manifested: receptive, independent and conflicted.

Practical implications

The findings of this study will aid instructors of undergraduate students by describing the likely reactions of those students to various ways of talking about Wikipedia. This information can help inform methods for teaching different kinds of students about the website.

Originality/value

Previous studies have shown how students use Wikipedia, as well as the attitudes of faculty toward Wikipedia. This study serves to bridge the gap between these areas, providing insight into how faculty and classmates’ attitudes influence student use of Wikipedia.

Abstract

Purpose

Recent advancements in wearable computing offer opportunities for art galleries to provide a unique experience. However, to ensure successful implementation of this new technology in the visitor industry, it is essential to understand user requirements from a visitor’s point of view. Therefore, the aim of this paper is to investigate visitors’ requirements for the development of a wearable smart glasses augmented reality (AR) application in the museum and art gallery context.

Design/methodology/approach

Interviews with 28 art gallery visitors were conducted and an affinity diagram technique was used to analyze the interviews.

Findings

The findings reveal that wearable AR is in its infancy and that technical and design issues have to be overcome for a full adoption. It reveals that content requirement, functional requirement, comfort, experience and resistance are important when developing and implementing the wearable AR application in the museum and art gallery contexts.

Originality/value

Mapping user requirements in the wearable smart glasses AR context using an affinity diagram is a new approach and therefore contributes to the creation of knowledge in the tourism domain. Practically, the area of wearable technologies and AR within the tourism and visitor industry context is still relatively unexplored, and the present paper provides a first foundation for the implementation of wearable smart glasses AR applications in the museum and art gallery context.

Abstract

Analyses the economic system slice‐wise, taking the main economic activities for a year together. Within this slice the development of the economic activities is characterized by plus or minus signs according to an increase or decrease of the activities. This yearly sequence of plus and minus signs is taken as a pattern. Analyses these economic patterns according to cybernetic and economic criteria. Sign‐equivalent patterns are taken together as groups. The chronological development of these groups gives the profiles of the economy. The development of profiles is quite concordant with the business cycle of the economy in question.

Abstract

Various ink formulations for inkjet printing on nylon66 carpet are prepared by using CI Acid Red 57, Natrosol and sodium alginate thickeners, ethylene glycol, diethylene glycol, and isopropanol with auxiliaries. The inks are characterised for their rheological, wetting, and storage stability properties. They were jetted by using a Printos P16 drop-on-demand jet print-head onto the nylon66 carpet materials, and the printed images were characterised by using an Image Xpert system.

The inks that contained the synthetic thickeners at the optimum ratio provide good printing and imaging properties, such as optical density, drop size, and depth of penetration into the substrate at pH 4-5. The optimised ink formulation is found to have good storage stability. The study has focused on ink formulations based on CI Acid Red 57. Ink formulations based on other colorants could also be studied in order to assess the applicability of the ink formulation system found for other colorants. The ink formulations developed could find both uses in industrial scale printing and low cost ink formulations for printing of nylon66 carpets.

Abstract

Purpose

This paper aims to explore a multi-stakeholder perspective on brand meaning co-creation in the context of the Olympic Games as a unique mega sports event brand with a strong brand identity, to understand how the brand manager may integrate such co-created meanings in a negotiated brand identity.

Design/methodology/approach

Using a qualitative methodology, the paper provides a tentative framework of co-created Olympic brand meanings by exploring the narratives of stakeholders’ brand experiences of the brand. Sixteen semi-structured interviews with a purposive sample of Olympic stakeholders were conducted and analysed to identify key meanings associated with the Olympic brand.

Findings

Through their transformational and social experiences of the Olympic brand, stakeholders co-create brand meanings based on Olympic values of excellence, friendship and respect. However, at the same time, they offer their own interpretations and narratives related to competing meanings of spectacle, exclusion and deceit. Alternative brand touchpoints were identified, including blogs; fan and sports community forums; educational and academic sources; and historical sources and literature.

Practical implications

The brand manager must become a brand negotiator, facilitating multi-stakeholder co-creation experiences on a variety of online and offline engagement platforms, and exploring how alternative brand touchpoints can be used to access co-created brand meanings.

Originality/value

The study contributes to tourism branding literature by providing exploratory evidence of how brand meanings are co-created in the relatively under-researched multi-stakeholder sports mega-event context.

Abstract

Purpose

The Nigerian Government has been left behind in the planning of homes for the senior citizens as they are aged and retire from service. The possible outcome is untimely death of many because of contagious illness associated with the dilapidated environment in their abode. Hence, this paper attempts to investigate the hindrances of home ownership faced by senior citizens and proffers possible policy solutions.

Design/methodology/approach

A phenomenology type of qualitative research was adopted and 30 participants were interviewed. That is, ten from four different state government agencies and 20 senior citizens using purposive and snowball sampling techniques and data saturation was also achieved. The data derived were analysed using MAXQDA 2018 and through a thematic analysis.

Findings

This paper found that Nigerian low-income senior citizens (LISCs) who owned houses lived more stable well-being. Whilst the level of home ownership was completely dissatisfying as failed mortgage finance, corruption in the pension scheme, relaxed National Housing Policy implementation and inadequate senior citizens’ home ownership policy were identified as the encumbrances.

Research limitations/implications

This paper is limited to exploring the root cause of LISCs’ inability to gain home ownership and proffering possible solutions. Future research is needed to use relevant information in advancing home ownership policy for the low-income groups across the states in Nigeria and other developing countries.

Practical implications

This paper recommended that government should impose housing construction on three acres and above, mitigate corruption, establish special housing loan scheme for senior citizens, sustain rent-to-own policy and land subsidy in cities to enhance senior citizens’ home ownership. These recommendations form part of the paper's practical implications.

Originality/value

This paper demonstrates that existing housing policies are yet to consider the senior citizens regarding enhancing their home ownership status.

Abstract

Purpose

This paper aims to propose a set of principles for implementation of successful post-disaster social recovery in-line with the concept of “building back better” (BBB).

Design/methodology/approach

A set of preliminary principles for post-disaster social recovery was established from literature review. The 2009 Victorian Bushfires was chosen as a case study to examine the implemented social recovery approaches and impacts.

Findings

Analysis of the literature and case study have led to the creation of a set of modified BBB principles for social recovery under two categories, first, community support and, second, community involvement. Key principles under first category include: providing personalized support for affected families, specialized support for vulnerable groups and improved psychological support; building community cohesion; and keeping the community informed. Key principles under second category include: involving the community in designing and implementing recovery projects; providing support to the community; and maintaining full transparency.

Research limitations/implications

This study focusses on one case study. The appropriateness and applicability of the proposed principles can be further tested using a range of different case studies in both developed and developing countries.

Practical implications

The principles presented should be incorporated into post-disaster social recovery programmes implemented by governments.

Originality/value

This research takes a unique look at drawing from international experiences to form a set of practical and universal principles to aid post-disaster social recovery as an important part of BBB.

Purpose

The purpose of this paper is to prepare and characterise various ink formulations for inkjet printing on nylon 66 carpet.

Design/methodology/approach

Various ink formulations were prepared using CI Acid Red 57, synthetic thickeners (BYK425 and BYK420), ethylene glycol, diethylene glycol, isopropanol with auxiliaries. The inks were characterised for their rheological, wetting and storage stability properties. The inks were jetted using a Printos P16 drop‐on‐demand jet print‐head onto nylon 66 carpet materials. The printed images were characterised using an ImageXpert system.

Findings

It is found that the inks containing the synthetic thickeners at the optimum ratio give good printing and image properties, such as optical density, drop size, and depth of penetration into the substrate at pH 4‐5. The optimised ink formulation is found to have good storage stability.

Research limitations/implications

The study focuses on ink formulations based on CI Acid Red 57. Ink formulations based on other colorants could also be studied in order to assess the applicability of the ink formulation system found for other colorants.

Practical implications

The ink formulations developed could find use in industrial scale printing.

Originality/value

Low cost ink formulations for printing of nylon carpets are novel.
