Purpose – This paper aims to report on production of the colour digital printing toners cyan, magenta and yellow. Colour digital electrophotographic printing is currently in high demand. The provision of a large colour gamut depends on appropriate selection of precise colourants to produce toner capable of producing a thin layer on paper. Design/methodology/approach – Printing toners were synthesised by the emulsion aggregation method, and then evaluated for chemical constitution and effects of the colourant substituents. Findings – Results demonstrated that increasing the polarity of a pigment produced better dispersion and lower particle size with narrower distribution and even better colour reproduction. While, changing a pigment’s characteristics did not affect the toner shape or its thermal properties. Practical implications – The developed method provides a simple way to synthesise colour printing toner. Social implications – Emulsion aggregation toners provide less hazardous materials during printing. Originality/value – Evaluations of the influence of solid-state parameters and physicochemical properties of the pigments on printing toner characteristics were done for the first time.

Purpose Many people in severe mentally disturbed states do not use language or other symbolic media well or coherently. Therefore, the non-verbal medium needs to be understood by workers with such people. The “Learning from Action” experiential workshop was developed in order to provide an opportunity to learn about hidden messages in the relationships and roles occurring in activities. In August 2017, a workshop was run for the first time in Japan. The purpose of this paper is to report the experience and dynamics observed by the three consultants, who are here the authors of this paper. Design/methodology/approach After the workshop all the staff and members, including interpreters, were invited to give feedback. Findings Analysis of the feedback data showed certain important dynamics, concerning especially dependence, cultural defences and the defensive role of activity in a multicultural context. Research limitations/implications This is an initial experience to be followed up by later feedback and further workshops. Practical implications Workers awareness of non-verbal communication within the roles of work activities is a training possibility. It faces various resistances including the mental health assumptions of meaninglessness of any communication outside the verbal. Originality/value This is a method of training not widely used even in European countries, and is the first in a country in the far east.

Purpose The purpose of this paper is to evaluate the model of a rear pressure bulkhead with different design optimizations to meet the pressurized cabin requirements of an aircraft. Design/methodology/approach This paper presents the results of the static analysis of a dome-shaped rear pressure bulkhead model designed in Catia-v5. Numerical analysis of model meshed in hyper-mesh and solved using Opti-Struct for iterative design optimizations. Findings All the iterative models are analyzed at 9 Psi. Rear pressure bulkhead designed with L-section stringer shows better results than the model optimized with T-section stringer for the same thickness. The model optimized with L-shaped stinger also reduces the weight of the bulkhead without affecting the structural integrity. Practical implications It has been concluded in this paper that the selection of specific shapes of the stringers shows a significant influence on weight reduction. Originality/value This paper provides a topical, technical insight into the design and development of a rear pressure bulkhead. It also outlines the future development of dome-shaped rear pressure bulkhead.

PurposeThe purpose of this paper is to demonstrate a “maintenance pathway” for ensuring a low false negative rate in closing investigations unlikely to lead to a clearance (detection).Design/methodology/approachA randomised controlled experiment testing solvability factors for non-domestic cases of minor violence.FindingsA random selection of 788 cases, of which 428 would have been screened out, were sent forward for full investigation. The number of cases actually detected was 22. A total of 19 of these were from the 360 recommended for allocation. This represents an improvement of accuracy over the original tests of the model three years earlier.Research limitations/implicationsThis study shows how the safety of an investigative triage tool can be checked on a continuous basis for accuracy in predicting the cases unlikely to be solved if referred for full investigations.Practical implicationsThis safety check pathway means that many more cases can be closed after preliminary investigations, thus saving substantial time for working on cases more likely to yield a detection if sufficient time is put into the cases.Social implicationsMore offenders may be caught and brought to justice by using triage with a safety backstop for accurate forecasting.Originality/valueThis is the first published study of a maintenance pathway based on a random selection of cases that would otherwise not have been investigated. If widely applied, it could yield far greater time for police to pursue high-harm, serious violence.

Purpose – The aim of this article is to investigate the organization of water cooperatives in Greece for the first time, as promoted by a spontaneous social mobilization called Initiative 136. The above attempt appears as an alternative proposition as opposed to the state-driven full privatization of EYATH S.A. Design/methodology/approach – This article presents previous work on water cooperatives and the negative effects of water privatization worldwide, relating it to water privatization in Greek reality through the prism of the current recession. Findings – While full privatization under the pressure of the economic crisis is very likely to yield significantly negative results, a transformation into a water cooperative might provide a viable solution. Research limitations/implications – Water cooperatives provide a solution for water distribution that is friendly for the consumer, the society and the environment. Practical implications – Application of a cooperative method of water provision in Greece could be a springboard for the use of the model in other areas. Originality/value – The article evaluates the privatization and cooperativization attempt of EYATH S.A. based on previous related research and considering Greece ' s current conditions.

PurposeA well-documented pattern in the literature concerns the outperformance of small-cap stocks relative to their larger-cap counterparts. This paper aims to address the “small-cap versus large-cap” issue using for the first time data from the exchange traded funds (ETFs) industry.Design/methodology/approachSeveral raw return and risk-adjusted return metrics are estimated over the period 2012-2016.FindingsResults are partially supportive of the “size effect”. In particular, small-cap ETFs outperform large-cap ETFs in overall raw return terms even though they fail the risk test. However, outperformance is not consistent on an annual basis. When risk-adjusted returns are taken into consideration, small-cap ETFs are inferior to their large-cap counterparts.Research limitations/implicationsThis research only covers the ETF market in the USA. However, given the tremendous growth of ETF markets worldwide, a similar examination of the “small vs large capitalization” issue could be conducted with data from other developed ETF markets in Europe and Asia. In such a case, useful comparisons could be made, so that we could conclude whether the findings of the current study are unique and US-specific or whether they could be generalized across the several international ETF markets.Practical implicationsA possible generalization of the findings would entail that profitable investment strategies could be based on the different performance and risk characteristics of small- and large-cap ETFs.Originality/valueThis is the first study to examine the performance of ETFs investing in large-cap stock indicesvis-à-visthe performance of ETFs tracking indices comprised of small-cap stocks.

Purpose Rather than an attempt to define or clarify resilience in terms of its characteristics, or its correspondence to reality, this paper is a series of reflections that leads to the notion of resilience as a way of being in the world. What is presented is not intended to be conclusive in any way. The paper aims to trigger thoughtful reflections that will lead to further conversations about the entailments and ethical concerns implicit in the concept of resilience. Design/methodology/approach The paper comprises reflections based on a selection of published ideas, as well as on personal engagement in the domains of ecology and the biology of cognition. In postulating that resilience may have a central, ineffable quality, the phrase “soul of” has been used as an approach to considering what such a quality may be. This formulation leads to a consideration about the nature of our relationships with the other such that the notion of resilience has become meaningful. Findings Language parses or chunks named ideas in a way that reveals some regularities and obscures others. The word resilience is one such chunk that historically has changed its meaning. Furthermore in the present the word refers to variable aspects or elements depending on the context of its usage. In the ecological context, resilience entails an ambiguous balance between persistence and change, and indeed this ambiguity may be necessary to accommodate the complexities. In all cases the author has considered, we are only concerned with resilience where there is an ethical dimension and this, inherently, must be multidimensional given the complexities of the systems being regarded. The author claims that the soul of resilience arises through an ethically oriented reflexive awareness of our dynamic flow in a relational embeddedness. Practical implications The practical implications of this paper are elusive, yet meaningful, as the paper attempts to open space for operating in an ethical and useful manner with ambiguous concepts and for avoiding the hubris of certainty. The paper is an explication of one of the ways of thinking inspired by second order science. Originality/value As the reflections in this paper are largely those original to the author, the ideas are original. Whether they have value depends on what ideas, attitudes, orientations and further reflections are triggered and whether these in turn implicitly or explicitly alter actions toward more effective care of our world. If reflection on resilience increases resilience, then this paper will have value.

Purpose – The purpose of this paper is to address issues of medical leadership within health systems and to clarify the associated conceptual issues, for example, leadership versus management and medical versus clinical leadership. However, its principle contribution is to raise the issue of the purpose or outcome of medical leadership, and, in this respect, it argues that it is to promote medical engagement. Design/methodology/approach – The approach is to provide evidence, both from the literature and empirically, to suggest that enhanced medical engagement leads to improved organisational performance and, in doing so, to review the associated concepts. Findings – Building on current evidence from the UK and Australia, the authors strengthen previous findings that effective medical leadership underpins the effective organisational performance. Research limitations/implications – There is a current imbalance between the size of the databases on medical engagement between the UK (very large) and Australia (small but developing). Practical implications – The authors aim to equip medical leaders with the appropriate skill set to promote and enhance greater medical engagement. The focus of leaders in organisations should be in creating a culture that fosters and supports medical engagement. Social implications – This paper provides empowerment of medical professionals to have greater influence in the running of the organisation in which they deliver care. Originality/value – The paper contains, for the first time, linked performance data from the Care Quality Commission in the UK and from Australia with the new set of medical engagement findings.
