Learner Responses

Purpose The purpose of this study is to understand how learners describe their experiences with short-term, introductory maker experiences and to test a method for assessing learners’ experiences authentic to short-term learning. Design/methodology/approach The authors collected written responses from participants at a two-day event, STEM Center Learning Days. Through an analysis of 707 unique instances of learner responses to participation in drop-in maker activities, they examined how participants describe their short-term learning experiences. Findings The authors found that although some activities appear to onlookers to create passive experiences for learners, these seemingly passive moments have a significant impact on learners. In addition, some learners described themselves as working in tandem with tools to make something work and other learners viewed the tools as working autonomously. They found that the assessment method allowed them to gain an understanding of how learners describe their experiences offering important implications for understanding short-term learning events. Originality/value The findings provide researchers studying short-term learning in its natural setting a new method to understand how learners make sense of their individual experience. Further, designers of short-term learning experiences may gain insights into their unique activities and indications of where additional guidance and scaffolds will improve small learning moments.

First Results

Purpose Elastomer seals are used in many applications. They are exposed to lubricants and additives at elevated temperatures, as well as mechanical stresses. They can only provide good sealing function when they have resistance to those factors. There are many elastomer-lubricant compatibility tests based on DIN ISO 1817 in industry. However, they are insufficient and costly. Correlations between the tests and the applications are inadequate. The purpose of this study is investigating lubricant compatibility of fluoroelastomers (FKM) seals in polyethylene-glycol (PG)- and polyalphaolefin (PAO)- based synthetic oils and developing a methodology to predict seal service life. Design/methodology/approach A new compatibility test which is more sufficient in terms of time and cost was developed and compared with a standard test, currently used in industry. Compatibility of FKM radial lip seals with PG- and PAO-based synthetic oils with different additives was investigated chemically and dynamically. Failure mechanisms were examined. Findings The new method and the Freudenberg Flender Test FB 73 11 008 showed similar results concerning damages and similar tendencies regarding wear. The additive imidazole derivative was the most critical. Static tests give indications of possible chemically active additives, but alone they are insufficient to simulate the dynamic applications. Originality/value The paper describes a new method to investigate elastomer-lubricant compatibility and gives first results with a variety of lubricants.

Purpose The purpose of the paper is to describe and analyse the evolution of the supplier base of a buying firm and the reasons behind these changes. Design/methodology/approach The paper is based on a case study of the changes over 52 years in a sub-set of the supplier base of a firm manufacturing fork-lifts. Findings The study shows that some relationships feature substantial longevity. However, the duration of one-third of the total relationships is shorter than five years. There was considerable variation over time in the dynamics of the supplier base in terms of entries and exits of suppliers. Owing to this variation, research findings and conclusions in short-term studies are heavily dependent on the specific conditions at the time of the study. Finally, no less than one-fourth of the terminated supplier relationships were reactivated later. Research limitations/implications The study was designed in a time when purchasing was considered entirely from the perspective of the buying firm. Further studies, therefore, must increasingly emphasise the role of suppliers and the interaction in the buyer–supplier relationships, as well as the embeddedness in networks. Originality/value The findings of the study are unique in two ways. First, they are based on systematic observations over more than 50 years. Second, the study involves the purchases of 11 components representing different technical and economic features. The (few) previous studies are based on much shorter time periods and involves fewer suppliers/components. Moreover, the findings regarding re-activation of terminated relationships represent unique contributions.

Purpose The purpose of this paper, builds on previous studies that explored the research patterns over 15 years, is to consider the current status of the integration of Lean and Six Sigma. More specifically, this research addresses whether Lean and Six Sigma are stronger together and explores the reasons why Lean researchers and practitioners may be less likely to integrate Six Sigma in their work. Design/methodology/approach The research utilises a survey of 25 established and respected academics and practitioners from 16 countries. The questionnaire is analysed using a direct content approach and coded in NVivo. Findings The findings suggest that challenges may lie in the perception and understanding of statistics as well as short-term rather than long-term focus on improvement. The findings also suggest that academics and practitioners believe that Lean Six Sigma has developed over time and will continue to develop and improve as a methodology rather than being replaced with a new methodology. Research limitations/implications The survey has a sample size of 25, albeit all respondents are established and very experienced practitioners and academics. Practical implications For organisations that are introducing or refreshing their continuous improvement initiatives, this research identifies some of the challenges and provides the opportunity to address them to maximise the opportunities for success and sustainability. Originality/value The value of this paper is that it further addresses the debate over the integration of Lean and Six Sigma for many organisations which still employ Lean alone, but beyond this it explores how they will continue to develop and whether they are a permanent edition to the quality management landscape or a transition to something else.

Purpose The purpose of this paper is threefold: to classify wildcards into three particular types sharing similar characteristics; use the Fuzzy TOPSIS as a new method in foresight to turn qualitative ideas into quantitative ones; and apply a combination of Fuzzy TOPSIS and a panel of experts to prioritize weak signals. Design/methodology/approach In this paper, the authors classify wildcards into three particular types which share similar character: natural wildcards, artificial wildcards (Degree 1) and artificial wildcards (Degree 2). Wildcards point to unexpected and surprising events including important results that can form watershed in the development of a specific trend. In addition, the authors present a Fuzzy TOPSIS model which can be used in various cases to prioritize a number of weak signals and put them in order, so that the most important ones are likely to yield the wildcard in the future Findings The authors presented a classification of wildcards with the same characteristics being natural wildcards, artificial wildcards (Degree 1) and artificial wildcards (Degree 2). The authors also prioritized the weak signals to deal with the most important ones and take appropriate action in advance so as to minimize possible damages and maximize the benefits of potential wildcards in an uncertain environment. Originality/value In this paper, the authors report on the prioritizing of weak signals by applying Fuzzy TOPSIS and classify wildcards. This is significant because, by identifying the most important weak signals, appropriate actions can be taken in the future if necessary. The paper should be of interest to readers in the area of participatory foresight.

Purpose The authors wanted to examine why undeclared workers had not received financial assistance in Europe during the pandemic and find the best way to help them and bring them out of the shadows. Design/methodology/approach To identify those whose paid work is entirely undeclared, a Eurobarometer survey of undeclared work in Europe is reported conducted in September 2019, just prior to the pandemic, and involving 27,565 face-to-face interviews in 28 European countries. Findings The paid work of one in every 132 citizens in Europe comprises wholly of undeclared work and one in 28 work at least some of the time in the undeclared economy. These workers have received no support, but they are more likely to be financially vulnerable. A high percentage of undeclared workers are widowed, divorced and living in households with multiple persons. Originality/value The authors argue that short-term support for these individuals could not only help them to survive the pandemic financially, but also transform undeclared work into declared work with long-term benefits for individuals and the wider economy.

Purpose The purpose of this paper is to discuss the major planning and implementation practices that should be followed in a short term international study trip (IST). The focus throughout is on how to utilize experiential learning to establish cultural competence. Design/methodology/approach The paper shows how to plan and manage an international MBA study trip to China using a specific case to illustrate the methods employed. Findings The use of a highly structured approach to an experiential learning exercise combined with a focus on key elements of cultural competencies creates a positive environment and leads to significant focused learning. Originality/value This paper fills three key gaps in the literature. First it uniquely focuses on the implementation of a conceptual framework that incorporates the types of cultural competency related learning that are to take place. Second, it illustrates how to design and implement an IST highlighting two key aspects of experiential learning: providing challenging experiences and encouraging reflection. Third, it focuses on a trip to China which, although one of the most popular destinations for business students, is lightly reviewed in the literature. This study fills a significant gap in the literature dealing with the management of short term study trips.

Purpose This paper aims to explore the gradual commercialisation of second homes in non-urban locations and identifie a spectrum that ranges from lending to rentals to home exchange. Design/methodology/approach This paper is a conceptual one based on a review of literature relating to the acquisiting and use of secondary residences or “second homes”. Findings This paper observes that the secondary residence is often the object of a material over-investment that is symbolic and mental. The owners never quite leave their main place of residence when in the secondary one. The result is not two complementary spaces, but a hybrid space made up of the interlocking of the two. This paper also concludes that digitalization has made it easier to rent a secondary residence for a short period of time, using for instance the Airbnb platform, thus making it more an object of trade than a second home. From a sustainability perspective, the COVID-19 pandemic is likely to bring to the relatively rapid growth of short-term renting a halt. Further, it may encourage owners to be more psychologically and physically invested in their secondary residence, thereby contributing more to the local economy. Originality/value Few authors have considered the way digital tools can alter the relation with the secondary place of residence.

Purpose This paper aims to investigate whether individuals’ planning horizon influences their decision to save privately for their retirement. Design/methodology/approach Focussing on Spain, this empirical research uses the fifth wave of the Survey of Health, Ageing and Retirement in Europe (SHARE)[1]. Logit models are estimated considering variables related to demographic characteristics, economic situation, education and cognitive abilities and psychological and social factors. Findings The results confirm that the planning horizon significantly influences the decision to save for retirement. Long-term planners are more likely to save for retirement than short-term planners. Originality/value Although previous literature has identified the planning horizon as a relevant variable in the decision to save for retirement, few empirical studies have evaluated their impact. This paper shows that it is important to develop habits of financial planning in societies, especially in societies with a prominent orientation towards the present.

Purpose – Technology foresight or technology futures analysis is increasingly being recognised as a tool for planning sustainable development. Similarly, as argued by many, biotechnology could be harnessed for sustainable development. Hence, the purpose of this paper is to map out foresight activities in the Indian biotechnology innovation system. Design/methodology/approach – The present paper has adopted a systemic approach to analyse the foresight activities in the Indian biotechnology sector. An online Delphi survey, including interviews, was conducted for 750 biotech units. Findings – The greatest need of foresight is felt in the biopharma sector, especially in the small- and medium-sized firms. The methodologies used are only pre-foresight in nature and for short-term time horizons. The output preferred is “setting the R&D planning and priorities”. “Assessing socioeconomic and environment impact” is not accorded a high priority. Most of the regulatory agencies do not carry out foresight exercises. Originality/value – The research holds significance for evolving sustainable development policy.
