Method Analysis

Purpose The purpose of this paper is to assess the performance of the stabilised moving least squares (MLS) scheme in the meshless local Petrov–Galerkin (MLPG) method for heat conduction method. Design/methodology/approach In the current work, the authors extend the stabilised MLS approach to the MLPG method for heat conduction problem. Its performance has been compared with the MLPG method based on the standard MLS and local coordinate MLS. The patch tests of MLS and modified MLS schemes have been presented along with the one- and two-dimensional examples for MLPG method of the heat conduction problem. Findings In the stabilised MLS, the condition number of moment matrix is independent of the nodal spacing and it is nearly constant in the global domain for all grid sizes. The shifted polynomials based MLS and stabilised MLS approaches are more robust than the standard MLS scheme in the MLPG method analysis of heat conduction problems. Originality/value The MLPG method based on the stabilised MLS scheme.

Purpose Reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The problem with developing a reputation of being something of an oracle in the business world is that all of a sudden, everyone expects you to pull off the trick of interpreting the future on a daily basis. Like a freak show circus act or one-hit wonder pop singer, people expect you to perform when they see you, and they expect you to perform the thing that made you famous, even if it is the one thing in the world you don’t want to do. And when you fail to deliver on these heightened expectations, you are dismissed as a one trick pony, however good that trick is in the first place. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Self Adaptive

Purpose A self-adaptive piston is designed for the compressional gas cushion press nanoimprint lithography system. It avoids the lube pollution and high wear of traditional piston. Design/methodology/approach The self-adaptive piston device consists of symmetrical piston bodies, piston rings and other parts. The two piston bodies are linked by a ball-screw. The locking nut adjusts the distance between two piston bodies to avoid the piston rings from being stuck. The piston rings are placed between two piston bodies. Findings The simulation results based on COMSOL indicate that cylinder vibration caused by self-adaptive piston is 15.9 times smaller than the one caused by a traditional piston. Originality/value The self-adaptive piston is superior to the traditional piston in decreasing cylinder vibration.

Purpose This paper aims to outline why design thinking is an engaging process and provide a methodical framework to approach complex, multi-disciplinary problems in ways that consistently yield solutions that are successful and often creative in unpredictable ways. It is a framework for thinking about complex, multidisciplinary problems and the one that applies to just about anything. Design/methodology/approach Service design is all about taking a service and making it meet the user and customer needs for that service. It can be used to improve an existing service or to create a new service from scratch. To adapt to service design, the designer will need to understand the basic principles of service design thinking and be able to focus on it. Findings This paper explores the possibilities for applying design thinking in the hospitality industry in general and hospitality education and research in particular. The functional areas of the hospitality profession are explored, evaluated and then integrated as a holistic design to provide coherence, connectivity and linkages. Originality/value The paper illustrates an application of design thinking to hospitality research and education.

Transient Heat Conduction Problem

Purpose Large structural objects, primarily concrete bridges, can be reinforced by gluing to their stretched surface tapes of fiber-reinforced polymer (FRP). The condition for this technology to work requires the quality of the bonding of FRP and the concrete to be perfect. Possible defects may arise in the phase of construction but also as a result of long-term fatigue loads. These defects having different forms of voids and discontinuities in the bonding layer are difficult to detect by optical inspection. This paper aims to describe the development of a rapid and nondestructive method for quantitative assessment of the debonding between materials. Design/methodology/approach The applied technique belongs to the wide class of active infrared (IR) thermography, the principle of which is to heat (or cool) the investigated object, and determine the properties of interest from the recorded, by an IR camera, temperature field. The methodology implemented in this work is to uniformly heat for a few seconds, using a set of halogen lamps, the FRP surface attached to the concrete. The parameter of interest is the thermal resistance of the layer separating the polymer tape and the concrete. The presence of voids and debonding will result in large values of this resistance. Its value is retrieved by solving an inverse transient heat conduction problem. This is accomplished by minimizing, in the sense of least squares, the difference between the recorded and simulated temperatures. The latter is defined as a solution of a 1D transient heat conduction problem with the already mentioned thermal resistance treated as the only decision variable. Findings A general method has been developed, which detects debonding of the FRP tapes from the concrete. The method is rapid and nondestructive. Owing to a special selection of the compared dimensionless measured and simulated temperatures, the method is not sensitive to the surface quality (roughness and emissivity). Measurements and calculation may be executed within seconds. The efficiency of the technique has been shown at a sample, where the defects have been artificially introduced in a controlled manner. Originality/value A quantitative assessment procedure which can be used to determine the extent of the debonding has been developed. The procedure uses inverse technique whose result is the unknown thermal resistance between the member and the FRP strip.

PurposeThe geopolitical relevance of the region with regard to clandestine and market interests exerting ecological pressures over mangroves and artisanal fishing thus raises awareness with regard to the local disaster's potentially global dimension. Delinking thus suggests divergent visibilization strategies regarding the narratives and framings of the region.Design/methodology/approachReflecting on previous ethnographic and quantitative research on the impacted livelihoods in the Canton of Muisne (Ecuador) in the aftermath of the earthquake of April 2016, this article explores some disruptive dimensions of the permanent disaster in the predominantly black Ecuadorian–Colombian border region.FindingsBy drawing on decolonial theory, as well as by shifting between a mainstream narrative of the disaster, on the one hand, and a “delinked narrative,” on the other, this article is in line with more recent publications arguing that neither local and time bound accounts of vulnerability, ethnicity and (in)visibility, nor mainstream depictions of a “lack of development” are able to generate the required knowledge to disrupt from this permanently neglected disaster.Originality/valueIn order to understand the disaster beyond its ostensibly local dimension, economic, environmental, as well as the geopolitical considerations are suggested, resulting in a different framing of the disaster.

Purpose – The purpose of this paper is to expand the burgeoning research, which provides evidence relating to the influence of religion upon work-related values. Design/methodology/approach – The authors employed a survey methodology to collect data across seven countries and six religions. Findings – The study provides evidence of differences as well as similarities in the way people belonging to different religions rank personal values. Thus, on the one hand, the authors can argue that religion helps shape our behavior and attitudes in the workplace, whilst at the same time, however, accepting the converging influence of globalization and/or the universality of some values that they include in their analysis. This finding leads the authors to focus upon a complex pattern of value variations and similarities across religions. Originality/value – Overall, the findings provide a glimpse into what the paper interprets as (just one dimension of) plurality within contemporary organizations to support the paradox perspective, popularized by Lewis and Smith and Lewis, who contend that organizations embed multiple tensions and dilemmas in an ongoing cyclical process. Hence the paper argues that the similarities and differences across religious affiliations are not “either/or” choices but dualities that must be dynamically balanced in order to simultaneously meet multiple employee needs. The paper concludes that managers and employees need to articulate and embrace paradoxes related to religion, in order to create an awareness of the influence of religion that leads to being inclusive.

Purpose – This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach – This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings – To say it is tough for business organizations today would be a massive understatement. Thanks largely to globalization and technological developments, the operating environment has arguably become more competitive than ever before. Firms thus need to constantly evolve in order to meet the array of new challenges which regularly face them. For those unable to adapt, survival and prosperity may ultimately be elusive. Change has invariably proved to be something of a double-edged sword. On the one hand, it can signal opportunity and prompt excitement and anticipation. But many others see change in terms of threat. Practical implications – The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value – The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Purpose – The purpose of this paper is to discuss the contribution of the Porter Report toward increasing the competitiveness of the Portuguese economy and highlights the factors that affected its operationalization. Design/methodology/approach – This paper considers the contributions of the Porter Report, entitled “Building the Competitive Advantages of Portugal”, presented in 1994, particularly with regard to the recommended clusters and public policies, as well as the assessment and warnings provided by Michael Porter in 2002, examining both in the present perspective. Findings – Although Michael Porter, in 2002, made a critical judgment about the country’s evolution since the 1994 report, it is clear that, on the one hand, the recommended development model attracted high attention and had positive repercussion in academic and business circles, while on the other hand, some of the objectives were achieved, albeit at a slower pace than would have been desirable. Political and economic context and the time period are relevant for all technological and geostrategic changes, among others. The accuracy of the diagnosis and the development model proposed by Michael Porter is confirmed and the difficulty in its implementation is highlighted. Originality/value – The analysis of the Portuguese evolution after Porter’s recommendations is instrumental in understanding the competitiveness and development challenges faced by a small peripheral economy in the European integration process. Understanding these difficulties and successes is of utmost importance in improving the definition and in the implementation of policies focused on the competitiveness of countries and regions.
