Social Uncertainty

Purpose – The purpose of this paper is to identify the most significant uncertainties for bioenergy applications, in order to identify factors determining the success of introducing bioenergy into the current energy system. Design/methodology/approach – A framework is built for identifying the most significant uncertainties based on studies exploring the positive potentials as well as possible negative effects of bioenergy. The framework is applied to explore uncertainties of bioenergy-based transport fuels and heat and power generation through two real life case studies. Findings – The results indicate that the most significant uncertainties are environmental and economic. Bioenergy applications have potential to mitigate climate change, but also come with negative environmental effects. Case studies show that operations in developing nations contain higher political/institutional and social uncertainty than those in developed countries, due to weaker regulations and enforcement. Research limitations/implications – The paper is part of an on-going research project. Results will be verified with stakeholder interviews and analysis. Further institutional analysis of the country settings is necessary. Practical implications – The use of a feedstock with high environmental, social and institutional uncertainties will lower public acceptance. Acting in accordance to the law is not sufficient to ensure sustainability and additional, voluntary measures should be undertaken. Originality/value – The paper identifies the most significant uncertainties for bioenergy. Uncertainties from social acceptance and institutional settings are higher in developing countries and acceptability requires more than following regulations.

Practical Implications

Purpose – This paper aims to investigate the strategies used by Swedish citizens to adapt to changing climate variability and extremes. There is an increasing consensus that individual adaptive capacities are critical to successfully adapt to climate change and achieve sustainable development. However, little is known about individual adaptive practices, particularly in developed countries. Design/methodology/approach – The study covered a variety of geographical areas and included single-case studies of specific locations, cross-case studies and country-wide studies. Data were collected through literature review, interviews with at-risk people, observation and group discussions with municipal staff. Findings – The paper provides an overview of Swedish citizens’ adaptive practices and highlights how institutional development efforts affect individuals and their activities, including the equitable distribution of adaptation needs and resources. The paper concludes that individual adaptive capacities do not necessarily translate into adaptation. Practical implications – The results show that planned interventions are required. They emphasise the importance of more people-oriented adaptation planning that fosters the sustainable transformation of cities, together with the role that South-North knowledge transfer can play in this context. Originality/value – The paper offers critical insights into the positive and negative effects of citizens’ adaptation strategies (based on criteria such as effectiveness, sustainability and equity), and it discusses their relevance in the formulation of development policies and programmes.

Purpose The purpose of this paper is to examine whether there is a meaningful difference, viewed from a financial perspective, in distinguishing between organised crime and terrorist organisations, with regard to the control and mitigation of the threats that they pose to society. Design/methodology/approach The paper uses conceptual models obtained from enterprise theory and economics, as well as criminology, and makes use of case studies through the application of these models. Findings The paper finds that when viewed from a financial perspective, there is no meaningful difference in distinguishing between the groups because many have undergone processes of convergence and transformation, such that they assume each other’s operational and motivational characteristics. However, the answer also depends on how precisely one defines each type of illicit group as well as the transitions they undergo. Originality/value The value of this paper is that it applies two separate models on interactions between organised crime and terrorist organisations, the terror–crime continuum and interaction spectrum, to real life situations. After assessing their validity for more recent examples of such illicit groups, it then provides a balanced argument as to distinguishing between organised crime and terrorism. One limitation towards the paper’s originality, however, is that it draws mainly from pre-existing literature.

Training Programmes

Purpose Tourism is one of the most notable features of the contemporary globalised world. The tourism industry is becoming increasingly vital to the economy of many developing and developed countries around the globe. The demand of the tourism industry has posed a challenge for tourism training providers to move towards a more responsive and internationalised curriculum to enhance work readiness for tourism graduates who are expected to work with an increased number of international tourists. The purpose of this paper is analyse whether and how internationalisation has been implemented in the tourism training programmes across six institutions in Vietnam. Design/methodology/approach The research deployed case studies as research strategy with interviews and document analysis as two instruments of data collection. Findings The major findings show that even though the tourism industry demands graduates to possess global competency, knowledge and skills, the curriculum does not prioritise the internationalisation dimensions and the faculty members are not facilitated to be internationally active in their roles. Overall, internationalisation is still fragmented and ad hoc in these institutions even though the private institutions in this research appear to be more responsive to the trend of internationalisation in education than their public counterparts. Research limitations/implications The paper provides recommendations on how to effectively embed internationalisation components into local tourism training programs in Vietnam. Originality/value The research bridges the gap in the literature on internationalisation of the local tourism programme in non-English-speaking countries.

Purpose The purpose of this paper is to review studies focusing on the magnitude of money laundering and their effects on a country’s economy. The relevant concepts are identified on the basis of discussions in the literature by prominent scholars and policy makers. There are three main objectives in this review: first, to discuss the effects of money laundering on a country’s macro-economy; second, to seek measurements from other scholars; and finally, to seek previous findings about the magnitude and the flows of money laundering. Design/methodology/approach In the first part, this paper outlines the effects of money laundering on macroeconomic conditions of a country, and then the second part reviews the literature that measures the magnitude of money laundering from an economic perspective. Findings Money laundering affects a country’s economy by increasing shadow economy and criminal activities, illicit flows and impeding tax collection. To minimise these negative effects, it is necessary to quantify the magnitude of money laundering relative to economic conditions to identify the most vulnerable aspects of money laundering in a country. Two approaches are used in this study: the first is the capital flight approach, as money laundering will cause flows of money between countries; the second is the economic approach for measuring money laundering through economic variables (e.g. tax revenue, underground economy and income generated by criminals) separately from tax evasion. Originality/value The paper offers new insights for the measurement of money laundering, especially for developing countries. Most methods in quantifying money laundering have focused on developed countries, which are less applicable to developing countries.

Purpose The purpose of this paper is to present site planning and design (SPD) relevant variables and items in practice for practitioners to better understand and implement SPD in green building projects. Design/methodology/approach The research methods include questionnaire survey and case studies in the context of China. A questionnaire survey was adopted to identify the importance of 13 variables and the corresponding 38 items in SPD of green residential buildings. Three green residential projects including one in Hong Kong and two in Mainland China were selected to investigate the SPD considerations in practice and to discuss the necessary improvement. Findings The results show that 12 out of the 13 variables of SPD in green buildings are involved in the three case projects to some extent, thereby underscore the importance of these variables. The potential improvement in real-life SPD of green buildings is also discussed such as adopting design-build and integrated project delivery methods and preserving and protecting cultural characteristics on site. Originality/value The research findings may serve as a reference for practitioners to better conduct SPD in green building projects.

Purpose – The paper aims to postulate as to whether the brand manager function and role is best placed for creating high growth, disruptive brand portfolios. As a potential solution toward resolving this, prescriptions for nurturing brand intrapreneurs are advanced to accelerate corporate entrepreneurial thinking and action based on the empirical case material. Design/methodology/approach – This paper draws from seven case studies of six large global consumer packaged goods (CPG) firms involved in strategic brand venturing activity. Interview quotations are used to provide an invocative account of key ideas and arguments in the paper. Data gathering comprised extensive documentation and observation, and 21 semistructured interviews with senior-level executives and entrepreneurs. Interviews ranged in length with a mean interview time of 1 hour 23 minutes. All interviews were recorded with interviewee permission and, subsequently, transcribed and analyzed. Within-case and across-case analyses were performed using the spiral methodology espoused by Creswell (2007). Findings – Findings are clustered under three themes: galvanic and savvy leaders, entrepreneurial program design and nuanced operating models. In particular, the simultaneous practice of external and internal venturing inside a single venturing unit was noted to generate unique learning and promote corporate entrepreneurial action. Research limitations/implications – While case studies offer a way of investigating complex real-life phenomena with multiple variables, their ideographic nature suffers from an inability to generalize findings to other populations. This research design is no different. Nevertheless, rigorous within-case and cross-case analyses were performed involving world-class CPG marketing corporations to arrive at the findings presented. Practical implications – Numerous prescriptions for implementing brand intrapreneurship are advanced in the paper. Originality/value – Although technology venturing is a well-researched topic, ambidextrous brand venturing groups among CPG corporations renown for their marketing and branding prowess are only beginning to catch-on in practice – this is one of the first empirical paper to enumerate the practices of brand intrapreneurship within a strategic brand venturing framework.

Purpose – The purpose of this study is to address the situation that although the theoretical benefits of using drama projects in the Teaching of English as a Foreign Language (TEFL) have been described in a number of studies, researchers have identified a lack of literature on their practical use, particularly in terms of different institutional settings, teaching styles, learning styles and proficiency levels. This paper therefore describes three case studies in universities in Korea, showing that the use of drama projects can be successfully used in different teaching situations and is an effective means of promoting meaningful language learning in students often demotivated by traditional methods and the test-driven classroom. Design/methodology/approach – In these adult-learner EFL settings, a process approach to drama projects aimed to promote meaningful language acquisition and holistic learning in students of different proficiencies and majors. Drama projects were used as: syllabus supplementation by an individual teacher in a Korean-mediated English program (Case Study 1); core content on an English-mediated pre-service teacher training course (Case Study 2); and syllabus content on a Freshman English program taught by 25 native-speaking instructors (Case Study 3). Data were collected from pre/post-course questionnaires, semi-structured interviews and students’ evaluations. These were then triangulated to identify trends in participant perceptions. Findings – Results indicated positive attitude change and promotion of cognition, positive affect and social skills in all three case studies, confirming earlier research findings and showing that the drama project is a viable and effective educational tool for the foreign language teacher, from individual syllabus supplementation to incorporation into a language program curriculum. Rather than resisting the innovation presented by drama projects, the adult learners involved welcomed the opportunities for creativity, autonomy, group work and performance. Originality/value – The practical confirmation of the theoretical benefits of EFL drama projects across individual and institutional settings indicates the potential value of including them in university language programs and teacher-training EFL curricula, enabling and encouraging language teachers to promote holistic, meaningful language learning.

Potential Applications

Purpose – While increased mechanization and automation make considerable contributions to mine productivity, unexpected equipment failures and imperfect planned or routine maintenance prohibit the maximum possible utilization of sophisticated mining equipment and require significant amount of extra capital investment. Traditional preventive/planned maintenance is usually scheduled at a fixed interval based on maintenance personnel's experience and it can result in decreasing reliability. This paper deals with reliability analysis and prediction for mining machinery. A software tool called GenRel is discussed with its theoretical background, applied algorithms and its current improvements. In GenRel, it is assumed that failures of mining equipment caused by an array of factors (e.g. age of equipment, operating environment) follow the biological evolution theory. GenRel then simulates the failure occurrences during a time period of interest based on Genetic Algorithms (GAs) combined with a number of statistical procedures. The paper also discusses a case study of two mine hoists. The purpose of this paper is to investigate whether or not GenRel can be applied for reliability analysis of mine hoists in real life. Design/methodology/approach – Statistical testing methods are applied to examine the similarity between the predicted data set with the real-life data set in the same time period. The data employed in this case study is compiled from two mine hoists from the Sudbury area in Ontario, Canada. Potential applications of the reliability assessment results yielded from GenRel include reliability-centered maintenance planning and production simulation. Findings – The case studies shown in this paper demonstrate successful applications of a GAs-based software, GenRel, to analyze and predict dynamic reliability characteristics of two hoist systems. Two separate case studies in Mine A and Mine B at a time interval of three months both present acceptable prediction results at a given level of confidence, 5 percent. Practical implications – Potential applications of the reliability assessment results yielded from GenRel include reliability-centered maintenance planning and production simulation. Originality/value – Compared to conventional mathematical models, GAs offer several key advantages. To the best of the authors’ knowledge, there has not been a wide application of GAs in hoist reliability assessment and prediction. In addition, the authors bring discrete distribution functions to the software tool (GenRel) for the first time and significantly improve computing efficiency. The results of the case studies demonstrate successful application of GenRel in assessing and predicting hoist reliability, and this may lead to better preventative maintenance management in the industry.

The Impact

Purpose The purpose of this paper is to explore the impact of behavioral interventions and nudging in dealing with the food waste problem. In particular, the authors implement an information campaign aiming to increase consumers’ awareness of the food waste problem. Design/methodology/approach In the period of three weeks, the authors observe intentions to prevent food waste and actual food waste of the consumers in a university restaurant serving ready meals. During the intervention period, consumers are exposed to an information campaign, designed to avoid consumers’ insufficient planning problem. Findings Consumers are willing to pay the same price for less food more often during the campaign than before the campaign, but the approximated impact on the food waste is not significant. Social emotions of guilt and shame are linked to consumers’ intentions to prevent food waste, suggesting channels to be included in a successful information campaign nudging consumers toward food waste reduction. Research limitations/implications The authors were not able to measure precisely food waste, but observed consumers in a real-life context. Consumers were not aware of the study, and made daily purchase decisions before and after the information campaign. Social implications Consumer behavior is at the core of the food waste problem in developed countries. It is important to understand how consumers can be nudged at low cost, using an information campaign, to change their attitude to food waste, and to decrease food waste. Originality/value The authors collected an original dataset on the impact of an information campaign, observing behavior of consumers in a real-life context.

PurposeWhile the investment in construction projects has increased over the past few decades, low construction project productivity (CPP) appeared to be persistent, thereby reflecting an “investment-in-failure” paradox between the investment and CPP. Hence, this paper aims to develop a systematic and holistic CPP evaluation framework to explain the apparent paradox in the construction industry.Design/methodology/approachThe paper first reviews the literature about the theories of system, production, principal–agent and project success evaluation to re-conceptualise the CPP and proposes a two-stage CPP evaluation framework. The framework is subsequently explored through a sequential qualitative mixed-methods design within the context of the Hong Kong construction industry by combining 32 semi-structured interviews with senior industry experts and exploratory case studies, with three real-life construction projects.FindingsThe paper identifies three system boundaries for CPP evaluation, that is, parameter, timeframe and stakeholder, and develops a two-stage CPP evaluation framework to indicate site efficiency and utilisation effectiveness, thereby accessing the productivity of both the construction and post-construction stages. The “investment-in-failure” paradox associated with current CPP evaluation approaches is primarily attributed to the narrowly defined CPP boundaries.Research limitations/implicationsThe qualitative exploration of the evaluation framework only focusses on the Hong Kong construction industry. Further case studies within other urban contexts could be used to improve the generalisability of the findings. Quantitative research is also necessary to advance theoretical development of the two-stage CPP evaluation.Practical implicationsThe systemic CPP conceptualisation and the two-stage CPP evaluation framework support the systems thinking of industry stakeholders and enable them to formulate holistic strategies for long-term CPP enhancement.Originality/valueThe research demonstrates the needs to expand the system boundaries of CPP to reflect its systemic value and to shift the paradigm of CPP evaluation from being output-orientated and quantity-focussed to being outcome-orientated and value-focussed.
