Ventilation Duct

PurposeThe purpose of this paper is to present the results of an experimental study aimed at analysing the effect of the roof tile air permeability on the thermal performances of ventilation ducts in the roof. The main reason underlying this study is the fact that the theoretical reference assumed for the manufacture and sizing of ventilation ducts (the accepted theory on roof ventilation) is clearly limited when applied to ducts which are not perfectly airtight (Hens) and results in an oversizing of the ventilation ducts.Design/methodology/approachA section of roof is built, covered with different tiles and environmental and meteorological data collected. The data are analysed statistically.FindingsThe results show that the permeability of the layer of tiles determines heat losses which are in addition to those connected with the stack effect in a perfectly airtight duct with the same features. The results also confirm the correlation which has already been demonstrated between the geometric ratio of the length of the duct divided by its height and the amount of heat dissipated by the roof (Sandberg and Moshfeg).Originality/valueThis study analyses the performance of the roofs only during the summer season. The research is therefore continuing with a long‐term (one year) analysis of the roofs characterised by a high level of roof tile permeability so as to understand the consequences that the presence of a ventilation duct in systems with air permeable roofing may have on the thermal efficiency of the roof.

Purpose The study investigates the long-term erosion of repeat-purchase loyalty among consumers who purchase brands in a one-year base period. Design/methodology/approach The study uses a five-year consumer panel of continuous reporters. We identify brand buyers in a base year, then calculate the proportion that fail to buy the brand in later years. We analyse the top 20 brands in 10 consumer goods categories. Findings We find pronounced erosion in repeat-buying over the long-term. The proportion of buyers from a base year that fail to buy in a later year increases steadily over time, from 57% in year 2 to 71.5% by year 5. Moreover, we identify brand and marketing mix factors linked to this over-time customer loss or erosion. Research limitations/implications The study provides evidence that consumers’ propensity to buy particular brands changes over a period of years, even though those brands continue to exhibit a stable market share. This evidence provides a different interpretation than the literature to date, which has viewed purchase propensities as fixed. Practical implications The study finds that store brands and niche brands exhibit lower levels of erosion in their buyer base; that a broad range is associated with lower erosion, and that high price promotion incidence is associated with lower erosion for manufacturer brands. Originality/value Loyalty erosion has been reported before (Ehrenberg, 1988; East and Hammond, 1996) but only over short periods. This study examines the phenomenon over five years, confirms that the rate of erosion does diminish over time, and that it is related to category and brand characteristics, as well as marketing mix decisions.

Purpose – The purpose of this paper is to introduce a methodology that can support the process of understanding and designing for the satisfaction of high-level needs in practice. The satisfaction of high-level needs has seldom been in focus when it comes to customer satisfaction surveys or the process of new product or service development. However, needs do occur on various levels, and the satisfaction of high-level needs actually appears to have the greatest potential for the creation of loyalty among customers and customer satisfaction. The satisfaction of high-level needs has furthermore been pointed out as a strategy for the creation of attractive quality. Design/methodology/approach – The paper is based on literature studies and the application of the Ideation Need Mapping (INM) methodology in a specific case. Findings – The paper presents the INM methodology that could be used for guiding product and service innovation in practice. More specifically, the methodology supports the process of understanding and designing for the satisfaction of high-level needs. Originality/value – This paper aims to contribute to envisioning and demonstrating how the understanding of, and design for, satisfaction of high-level needs can be done in practice.

Purpose This paper aims to examine the importance of celebrity brands in influencing consumer perceptions of celebrity authenticity, which drives positive consumer attitudes and intentions. In addition, the notion of low-celebrity investment is investigated as a factor that diminishes the positive outcomes associated with celebrity brands. Design/methodology/approach Study 1 examines the effect of brand situation (endorsement versus celebrity brand) on consumer attitudes and intentions. Studies 2 and 3 investigate the role of celebrity authenticity in explaining the effects observed in Study 1. Study 4 examines celebrity investment as a bound of the phenomenon. Findings Study 1 demonstrates that consumers report heightened attitudes and intentions towards celebrity brands when compared to endorsements. Studies 2 and 3 provide evidence that authenticity explains the effects observed in Study 1. Results of Study 4 show that when consumers are aware of low-celebrity investment, the celebrity is viewed as inauthentic regardless of brand situation. Research limitations/implications This research is limited as it focuses only on known celebrity endorsers who were matched with products that had a high level of fit. In addition, purchase intentions were measured as opposed to the study of actual purchase behaviour. Practical implications This research has important implications for the development of endorsements and celebrity brands by demonstrating that consumers view celebrities as authentic when they are involved with brands for reasons other than monetary compensation. Originality/value This research shows that consumers have heightened attitudes and intentions towards celebrity brands compared to endorsements. This research identifies celebrity authenticity as the process underlying the observed phenomenon. However, celebrity investment is identified as a boundary condition demonstrating that knowledge of low investment results in a celebrity being viewed as inauthentic.

Purpose This study aims to examine humans’ reactions to service robots’ display of warmth in robot-to-robot interactions – a setting in which humans’ impressions of a service robot will not only be based on what this robot does in relation to humans, but also on what it does to other robots. Design/methodology/approach Service robot display of warmth was manipulated in an experimental setting in such a way that a service robot A expressed low versus high levels of warmth in relation to another service robot B. Findings The results indicate that a high level of warmth expressed by robot A vis-à-vis robot B boosted humans’ overall evaluations of A, and that this influence was mediated by the perceived humanness and the perceived happiness of A. Originality/value Numerous studies have examined humans’ reactions when they interact with a service robot or other synthetic agents that provide service. Future service encounters, however, will comprise also multi-robot systems, which means that there will be many opportunities for humans to be exposed to robot-to-robot interactions. Yet, this setting has hitherto rarely been examined in the service literature.

Practical Implications

Purpose The purpose of the viewpoint is to examine the various ways in which the pandemic has exposed structural vulnerabilities in global business infrastructures that have long existed and been long ignored. It urges business leaders not to return to a “new normal” but make fundamental changes to ensure that their businesses are truly resilient and can withstand future threats more effectively. Design/methodology/approach The viewpoint looks at the various kinds of vulnerability to which businesses are exposed – such as supply chain, human capital, cyber security and climate change – and proposes ways to ensure that businesses, as well as shareholders and government entities work together to build true resilience. Findings At its core, the viewpoint exposes the various ways in which businesses have turned a blind eye to vulnerabilities that have always lurked just below the surface and suggests. The argument is that to secure the long-term future of our global business system, we can no longer remain oblivious to fundamental weaknesses in our infrastructures. Research limitations/implications The viewpoint looks selectively at the available data and is, therefore, by definition, subjective and non-comprehensive. Practical implications If businesses and shareholders truly take the recommendations of this viewpoint to heart, we can build a more resilient future through long-term investments in risk management infrastructures of all kinds that will secure a more prosperous and stable future. Social implications Developing a more resilient and stable global business infrastructure will help reduce the business volatility deriving from last minute responses to predictable threats. This will, in turn, help provide more stable, fulfilling employment, especially in developing countries that will act as a fly wheel for the secure development of human potential around the world. Originality/value While there has been much speculation of what the “new business normal” will look like once the pandemic has been conquered, this is, the author believes, the first piece to look concretely on how we can not only “build back better” but build back more soundly for the long term.

Purpose This paper aims to highlight the accountability reporting objectives of four Māori-controlled organizations. The examples cited reflect the core values of the indigenous Māori people of New Zealand (Aotearoa) and help demonstrate how these values are manifest in the accountability reporting of Māori-controlled organizations. Design/methodology/approach Narrative sections of ten annual reports of two small and two large Maori organizations, drawn variously from their financial years ending in the calendar years 2009 to 2014, are read closely. These organizations represent diverse tribal and regional associations in terms of size, scope and structure; and in terms of the business, social and cultural activities they pursue. Findings Three core Māori values are identified: spirituality (wairuatanga); intergenerationalism and restoration (whakapapa); and governance, leadership and respect (mana and rangatiratanga). The commitment to these values and the way this commitment is reflected in accountability reports of Maori organizations, is presented. Originality/value The examples provided, and the associated discussion, should help inform reporting initiatives of organizations that are seeking better accountability in terms of their long-term engagement with indigenous communities, the environment and broader society.

Purpose The purpose of this paper is to analyze provisions which are related to court’s intervention over an arbitral tribunal’s jurisdiction under the revised Korean Arbitration Act (2016) and the UNCITRAL Model Law. Design/methodology/approach The author studies a theory about court’s intervention over an arbitral tribunal’s jurisdiction by studying some scholarly writings and compares the revised provisions in the KAA (2016) with those in the KAA (2010) and the UNCITRAL Model Law (2006). Findings There is no clear and internationally unified answer to which theory between the prima facie test and the full review test is appropriate for court’s intervention to arbitration. The analysis of the provision shows that the revised ones in the KAA (2016) will make arbitration to be conducted faster and more efficiently by giving practical answers to issues raised. Research limitations/implications It has been just over one year since the KAA (2016) became effective, so it limits evaluation on whether these revised provisions related to court’s intervention over jurisdiction of arbitral tribunal is successful or not. Originality/value This study is comparatively new one after the KAA (2016) became effective. So, it is expected to provide a guidance for further studies.

Purpose – Family businesses represent the largest share of small-sized firms in majority of economies around the world. Having in mind the global economic situation this trend is expected to be continued. With the goal of better understanding of the process of transferring the business to the next generation, which ensures a long-term success, the purpose of this paper is to investigate expectations of student’s with family business background. Design/methodology/approach – The research addresses the issue of an individual’s perception of entrepreneurship and the related factors that influence individual’s decision on whether to build a career as an employee, become a successor of family business or start own business as an independent entrepreneur. The authors separately analyzed West European (data from another study), East European and Slovenian senior student population for the purpose of comparative study. Students were surveyed and binominal regression was used for statistics. Findings – The results show differences between investigated populations and positions Slovenian students in the mean. The authors anticipate that differences are caused by historical, cultural and educational backgrounds. This challenging area is raising a lot of sub-questions for possible future research. Originality/value – The value of the study is in the replication of the existing methodology from the benchmarking study and result comparison.

Purpose – The purpose of this paper is to analyse the relationship between the environmental management of purchases and firm performance. The authors examine the moderating role played by two variables: the establishment of long-term relationships with suppliers and the strategic integration of the purchasing function. Design/methodology/approach – The authors conduct an empirical study on a sample of 100 Portuguese firms. Findings – Evidence reveals that green purchasing management improves the performance of the purchasing function, although the impact is greater when the organisation forges lasting alliances with its suppliers. Originality/value – This paper contributes to the study of the consequences of introducing environmental practices into the purchasing function, especially with regards to the formation of a panel of sustainable suppliers. Specifically, this research provides evidence to show that the implementation of those practices has positive impacts on the operating performance of the purchasing function and that the said effect is greater when a firm establishes long-term relationships with its suppliers.
