Abstract
Purpose
The purpose of this paper is to show how simulation of the flow of particulates and fluids using discrete element modelling (DEM) and smoothed particle dynamics (SPH) particle methods, offer opportunities for better understanding the dynamics of flow processes.
Design/methodology/approach
DEM and SPH methods are demonstrated in a broad range of computationally‐demanding applications including comminution, biomedical, geophysical extreme flow events (risk/disaster modelling), eating of food by humans and elite water‐based sports.
Findings
DEM is ideally suited to predicting industrial and geophysical applications where collisions between particles are the dominant physics. SPH is highly suited to multi‐physics fluid flow applications in industrial, biophysical and geophysical applications. The advantages and disadvantages of these particle methods are discussed.
Research limitations/implications
Research results are limited by the numerical resolution that can currently be afforded.
Practical implications
The paper demonstrates the use of particle‐based computational methods in a series of high value applications. Enterprises that share interests in these applications will benefit in their product and service development by adopting these methods.
Social implications
The ability to model disasters provides governments and companies with the opportunity and obligation to use these to render knowable disasters which were previously considered unknowable. The ability to predict the breakdown of food during eating opens up opportunities for the design of superior performing foods with lower salt, sugar and fat that can directly contribute to improved health outcomes and can influence government food regulatory policy.
Originality/value
The paper extends the scale and range of modelling of particle methods for demanding leading‐edge problems, of practical interest in engineering and applied sciences.

Abstract
Purpose
Although the benefits that individuals obtain from trait mindfulness and functional flexibility have been well documented in the research literature, one crucial gap is the lack of evidence clarifying whether trait mindfulness and functional flexibility might benefit all age groups. Using the moderating effect of age among salespeople, this research analyzes the effects of trait mindfulness and functional flexibility regarding sales performance based on the conservation of resource theory.
Design/methodology/approach
Survey data were collected from 227 salespeople across 120 companies located in Bangkok, Thailand. The data were analyzed using partial least squares structural equation modeling.
Findings
The analysis shows that the positive effect of trait mindfulness on sales performance is more substantial for older salespeople than their younger counterparts. Although the analysis shows that functional flexibility is positively associated with sales performance, the positive relationship is only supported for younger salespeople. For older salespeople, available flexibility does not positively affect sales performance.
Practical implications
Based on the findings, developing trait mindfulness and functional flexibility in salespeople could be a valuable area of focus for sales organizations' human capital development policies. Although the intervention to develop trait mindfulness could be provided to all salespeople, the functional flexibility enhancement component should be delivered specifically to younger salespeople who may experience more significant gains from the training.
Originality/value
The results address the gap in the existing research that lacked evidence as to whether trait mindfulness and functional flexibility similarly affect the work performance of older and younger people. In particular, this study offers new insight into how age differences influence the benefit of trait mindfulness and functional flexibility across different age groups of individuals.

Abstract
The manager must take into account various human factors when introducing computers into the library. A survey of literature reveals the key fears of employees involved in library automation — to be concerned with job security, job satisfaction and health and safety. These findings are compared with data collected from a questionnaire administered to staff in four libraries, all in the process of automating various tasks. The effects of computerisation of the library service on users is also examined, with an analysis of literature and a questionnaire sent to 30 students in the College for the Distributive Trades. The author discusses ways in which the manager can interest and motivate staff by eliminating causes of dissatisfaction and by taking positive steps in appealing to employees' self‐interest in the possibilities of career advancement and the challenge of mastering something new. Staff selection procedures need to be amended to acquire the necessary skills, and training should be ongoing. The response of users to library automation is often enthusiastic but real benefits can be difficult to measure. The onus is ultimately on librarians to demonstrate that they still have a key role to play in the provision of information.

Abstract
Participatory action research (PAR) is a qualitative research methodology with a dynamic and powerful potential in both rural and urban contexts. PAR can account for social forces and macro systems of injustice which affect the lives of people within a community and thus achieve what Prilleltensky (2003) termed ‘psychopolitical validity’. This chapter explores its efficacy in research with Australian Aboriginal groups. It is contended that PAR is an invaluable approach in conducting research with such communities. PAR has the potential to empower Indigenous communities in ways that quantitative designs simply cannot.

Abstract
In this chapter I claim that climate change poses important questions of global justice, both about mitigating the change that is now under way and about adapting to its consequences.1 I argue for a mixed policy of mitigation and adaptation, and defend one particular approach to mitigation. I also claim that those of us who are rich by global standards and benefit from excess emissions have strenuous duties in our roles as citizens, consumers, producers, and so on to reduce our emissions and to finance adaptation.

This study investigates the effect of continuous improvement initiatives in streamlining HRM practices in Sri Lanka.
Abstract
Purpose
This study investigates the effect of continuous improvement initiatives in streamlining HRM practices in Sri Lanka.
Design/methodology/approach
Survey methodology was used and 217 respondents who fulfilled the selection criteria set for the study responded. Structural equation modelling was performed to examine the hypothesized relationships.
Findings
The analysis supported the hypotheses that continuous improvement initiatives significantly positively influence to streamline HRM practices of performance management, job-related training, employee involvement and team work.
Practical implications
Continuous improvement initiatives that are aligned with the strategic direction of firms guide to design and implement better focused HRM practices.
Originality/value
The failure to streamline HRM practices in accordance with continuous improvement initiatives has been identified as a key barrier for the effective utilization of human resources. Although continuous improvement initiatives demand changes in the way HRM is practiced, so far, little empirical attention has been paid to understand the implications of continuous improvement initiatives for HRM practices.

Abstract
Purpose
To grow, any field of research must both encourage newcomers to work within its boundaries, and help them learn to conduct excellent research within the field’s parameters. This paper aims to examine whether the existing body of neuromarketing literature can support such growth. Specifically, the authors attempt to replicate how a newcomer to the field of neuromarketing would go about orienting themselves to the field and learn how to conduct excellent neuromarketing research.
Design/methodology/approach
A total of 131 papers, published in the areas of “neuromarketing” and “consumer neuroscience” were downloaded and then identified as conceptual or empirical in nature. A separate database was created for each type of research paper and information was recorded. For both conceptual and empirical papers, the citation details, notably year of publication, journal, journal ranking and impact factor were recorded. Papers were then descriptively analysed with regards to number of publications over the years, content and journal quality.
Findings
It is found that interest in the field is growing, with a greater variety of topics and methods appearing year on year. However, the authors also identify some issues of concern for the field if it wishes to sustain this growth. First, the highly fragmented literature and the lack of signposting makes it very difficult for newcomers to find the relevant work and journal outlets. Second, there is a lack of high-quality, user-oriented methodological primers that a newcomer would come across. Finally, neuromarketing as it appears to a newcomer suffers from a lack of clear guidance on what defines good vs bad neuromarketing research. As a large majority of the reviewed papers have appeared in lower-ranked journals, newcomers might get a biased view on the acceptable research standards in the field.
Originality/value
The insights from the analysis inform a tentative agenda for future work which gives neuromarketing itself greater scientific purpose, and the potential to grow into a better-established field of study within marketing as a whole.

The purpose of this paper is to examine the structure of juvenile psychopathy, as measured by the Psychopathy Checklist: Youth Version (PCL: YV).
Abstract
Purpose
The purpose of this paper is to examine the structure of juvenile psychopathy, as measured by the Psychopathy Checklist: Youth Version (PCL: YV).
Design/methodology/approach
Using a sample of 2,042 male youths from the USA, Canada, and the UK, the study was a conceptual replication of Bishopp and Hare’s (2008) multidimensional scaling (MDS) analysis of adult male offenders assessed with the Psychopathy Checklist-Revised.
Findings
The scaling analyses generally replicated those obtained by Bishopp and Hare, providing support for a multidimensional, four-factor model of juvenile psychopathy similar to that obtained with adults. However, a small number of items fell outside their predicted regions. Slight differences in the structure of juvenile psychopathy were found for incarcerated and supervised samples of youth, with the four-factor model breaking down slightly for the supervised sample. Item misplacements may indicate that certain items on the PCL: YV are being misinterpreted, reflect different dimensions for different samples, or cannot be reliably measured. Future research should examine these possibilities, with special attention being paid to supervised samples.
Originality/value
To the authors’ knowledge, this is one of the first known attempts to use MDS analysis to examine the psychopathy structures that emerge for male juvenile offenders. The greater nuances afforded by using MDS offer a more comprehensive understanding of psychopathy between incarcerated and supervised youth using the PCL: YV.
