A Mie-Grüneisen mixture Eulerian model for underwater explosion
Authors: Wu Zongduo , Zong Zhi , Sun Lei 
Published: May 2014

Purpose
– The purpose of this paper is to provide an improved Mie-Grüneisen mixture model to simulate underwater explosion (UNDEX).

Design/methodology/approach
– By using Mie-Grüneisen equations of state (EOS) to model explosive charge, liquid water and solid structure, the whole fluid field is considered as a multi-phases mixture under Mie-Grüneisen EOS. Then by introducing auxiliary variables in Eulerian model and using mass fraction to establish a diffusion balance, a new improved Mie-Grüneisen mixture model is presented here. For the new reconstructed mixture model, a second order MUSCL scheme with TVD limiter is employed to solve the multi-phase Riemann problem.

Findings
– Numerical examples show that the results obtained by Mie-Grüneisen mixture model are quite closed to theoretical and empirical data. The model can be also used in 2-D fluid-structure problem of UNDEX effectively and it is proved that the deformation of structure can be clearly described by mass fraction.

Research limitations/implications
– The FVM model based on mass fraction can only describe the motion of compressible material under impact. Material failure or large deformation needs a modification about the EOS or implementations of other models (i.e. FEM model).

Originality/value
– An improved non-oscillation Mie-Grüneisen mixture model, which based on mass fraction, is given in the present paper. The present Mie-Grüneisen mixture model provides a simplified and efficient way to simulate UNDEX. The feasibility of this model to simulate the detonation impacts on different mediums, including water and other metal mediums, is tested and verified here. Then the model is applied to the simulation of underwater contact explosion problem. In the simulation, deformation of structure under explosion loads, as well as second shock wave, are studied here.
Numerical analysis of characteristics of the wind caused by methane-air explosion
Authors: Zhang Qi , Pang Lei , Lin Dachao 
Published: May 2014

Purpose
– The high-velocity wind caused by a methane-air explosion is one of the important hazardous effects in explosion events of coal mines, and, however, until now it has not been received much attention from scientific works. The paper aims to discuss this issue.

Design/methodology/approach
– In consideration of the difficulties in observing particle velocities of high-velocity flows, this work presented a study to reveal the regularity during a methane-air explosion happening in the tunnel of coal mine through the numerical analysis approach.

Findings
– The strong wind caused by a methane-air explosion is a significant hazard and can cause damage in the accidents of methane-air explosion in underground coal mines, especially at structural opening, according to this work. Obtained results show that maximum particle velocity of the high-velocity wind occurs in the outside region of the premixed area, with a peak value of 400∼500 m/s, and the peak velocity of the high-velocity wind decreases exponentially with distance beyond the premixed area.

Originality/value
– The objective of this work was to examine the effect of wind caused by a methane-air explosion in a tunnel. Other information, such as shock wave and flame and temperature distribution, has been reported in the previous literatures. However, in the accidents of methane-air explosion in underground coal mines, some phenomena (structural opening is destroyed badly) can not be understood by using shock wave and flame and temperature distribution caused by the explosion. The strong wind caused by a methane-air explosion is another significant hazard and can cause damage in the methane-air explosion accidents in underground coal mines, especially at structural opening, according to this work.
A two-step Taylor-Galerkin formulation for fast dynamics
Authors: Abd. Karim Izian , Hean Lee Chun , J. Gil Antonio , Bonet Javier 
Published: May 2014

Purpose
– The purpose of this paper is to present a new stabilised low-order finite element methodology for large strain fast dynamics.

Design/methodology/approach
– The numerical technique describing the motion is formulated upon the mixed set of first-order hyperbolic conservation laws already presented by Lee et al. (2013) where the main variables are the linear momentum, the deformation gradient tensor and the total energy. The mixed formulation is discretised using the standard explicit two-step Taylor-Galerkin (2TG) approach, which has been successfully employed in computational fluid dynamics (CFD). Unfortunately, the results display non-physical spurious (or hourglassing) modes, leading to the breakdown of the numerical scheme. For this reason, the 2TG methodology is further improved by means of two ingredients, namely a curl-free projection of the deformation gradient tensor and the inclusion of an additional stiffness stabilisation term.

Findings
– A series of numerical examples are carried out drawing key comparisons between the proposed formulation and some other recently published numerical techniques.

Originality/value
– Both velocities (or displacements) and stresses display the same rate of convergence, which proves ideal in the case of industrial applications where low-order discretisations tend to be preferred. The enhancements introduced in this paper enable the use of linear triangular (or bilinear quadrilateral) elements in two dimensional nearly incompressible dynamics applications without locking difficulties. In addition, an artificial viscosity term has been added into the formulation to eliminate the appearance of spurious oscillations in the vicinity of sharp spatial gradients induced by shocks.
Austerity and financial governance: a UK case study of the National Health Service
Authors: Prowle Malcolm , Harradine Don 
Published: May 2014

Purpose
– This research concerns the issue of financial governance within the UK NHS and aims to assess the effectiveness of existing financial governance arrangements in the main providers of health services in the UK. Also considered is the importance of good financial governance in a time of financial austerity.

Design/methodology/approach
– The primary research for this project was based on the use of a questionnaire to all finance directors in NHSTs in England supported by semi-structured interviews with: finance directors, non-executive directors, executive directors and senior finance staff.

Findings
– Among the main findings of the study were: certain financial management systems were not prioritised in line with what is seen as good practice; existing financial management systems were not always seen as adequate for the achievement of good financial governance; there was sometimes a lack of understanding of financial issues by non-executive directors; and the complexity of the NHS funding process often resulted in opaqueness of the financial risks.

Research limitations/implications
– The research is limited by the relatively small coverage of NHS trusts but this has been compensated for by a series of in-depth interviews with key stakeholders in the governance process.

Practical implications
– Weaknesses in financial governance could result in further scandals which result in loss of life and poor patient care.

Originality/value
– There are many papers on the issue of governance in the public sector in general and the NHS in particular. However, there is little published on the issue of financial governance in the NHS. Also of great value is the emphasis on strengthening financial governance in an era of austerity
Collaboration between philanthropic foundations and government
Authors: Almog-Bar Michal , Zychlinski Ester 
Published: May 2014

Purpose
– The aim of this paper is to examine collaboration between the government and philanthropic foundations in the age of new governance. This focuses on analysing the relationship that was formed between PFs and the government in Israel during the development and operation of two joint projects initiated by PFs, which aimed to promote collaboration between the two sectors in the fields of children at risk and the public education system.

Design/methodology/approach
– Qualitative, thematic content analysis was used to study the relationships that emerged between the PFs and the government. Data were collected from an examination of documented materials and interviews with key participants in the two projects from both parties.

Findings
– The article presents the interface between government and philanthropic foundations in the age of new governance. Several major factors that shape these relations in collaborative projects emerged from the comparative analysis of the two case studies and are relevant to public sector management: the different perceptions of government and philanthropic foundations that guide the collaborations, the politics of collaboration and the power relations between PFs and government.

Research limitations/implications
– Further research might examine other examples of collaboration between PFs and government, since the research reported here comprises only two case studies.

Originality/value
– As collaborations between government and philanthropic foundations are expanding in many countries as part of new-governance structures, the article presents a valuable insight for both academics and practitioners about relationships between these two sectors, and especially collaboration that involves actors from the New Philanthropy.
Collaborative development of enterprise policy
Authors: Woods Megan , Parker Miles Morgan 
Published: May 2014

Purpose
– The aim of this paper is to integrate an augmented version of the Thompson et al. model of enterprise policy, delivery, practice and research with services marketing models including SERVQUAL and strategic conversations; and demonstrate a practical application of the analysed through the application of N-Vivo qualitative data classification software to create more satisfying enterprise policy recommendations that better reflect the voices of SMEs and other stakeholders.

Design/methodology/approach
– A five-stage iterative process model to integrate stakeholder input into enterprise policy recommendations is developed through integrating services marketing theory and the Thompson et al. model into a field study of community conversations hosted by the Tasmanian Department of Economic Development, Tourism and the Arts, Regional Development Australia's Tasmanian committee, and local governments.

Findings
– The five-stage iterative model leverages strategic conversations, analysis (through N-Vivo), comments and revisions, recommendation co-creation, and policy assessment using SERQUAL to craft more satisfying policy recommendations.

Research limitations/implications
– The first limitation was the time and costs associated with conducting the community consultation workshops and analysing the data. The second limitation was the inability to craft policy quickly in response to a changing environment due to the time taken to collect and transcribe the data, undertake the analysis, and develop and report policy recommendations. The third limitation was the complexity of coordinating three levels of government, which took time and effort because each level had different interests and time frames and were at times distracted by other priorities.

Originality/value
– This paper contributes to better enterprise policy by providing a process model developed using both theory and a field study to illustrate how policy makers can co-develop policy that is more satisfying to policy stakeholders.
Social entrepreneurship and the negotiation of emerging social enterprise markets
Authors: Gawell Malin 
Published: May 2014

Purpose– Sweden, and many other countries, has, during the twentieth century, developed a rather large public sector providing social welfare services to citizens. Only to a small extent were private for- or nonprofit organizations providing these services. During the last decade we have seen a shift towards more services being provided by private for- and nonprofit actors. This shift means that roles are reconsidered, renegotiated and reconstructed. In this debate social entrepreneurship, social enterprises and innovation are emphasized. The aim of this paper is to problematize and analyze how social entrepreneurship and social enterprises relate to public sector management and governance.Design/methodology/approach– In the paper theories on (social) entrepreneurship and innovation is combined with theories focusing on welfare structures. Empirically, the analysis is based on the current policy development in Sweden and five social entrepreneurship initiatives.Findings– The analysis discloses the relationship between the public sector and social entrepreneurship as negotiation of emerging social enterprise markets in which aspects as the creation of value, dependencies and innovation are emphasized. Even if the study has a geographical focus both theoretical contributions and implications for policy and practice can be of use also in other contexts.Originality/value– Through combining social entrepreneurship with welfare services and public management this empirically based study contributes both to problematize and align the emerging field of social innovation.
Developing creative leadership in a public sector organisation
Authors: Anne Loewenberger Pauline , Newton Mark , Wick Kylie 
Published: May 2014

Purpose– This paper aims to demonstrate the effective development of creative and innovative capability in a rigid bureaucratic public sector environment of an area of the British Transport Police, championed by the Area Commander and informed by extant literature.Design/methodology/approach– The focus is on an intervention that addressed two related issues suggested by extant literature, cognitive blocks to creative thinking and organisational barriers. A diagnostic assessment of the climate for creativity prompted reflection leading to simultaneous interventions, combining supervisory and senior management support with a structured process of creative problem solving focusing on problems generated at a strategic level.Findings– This has proved highly effective. At the end of the first year, five six-week cycles had already resulted in more than 600 new ideas, of which 52 were in the pipeline and 13 had already been endorsed. Few required financial investment and have increased effectiveness and optimised use of resources – literally doing more with less. Evidence is emerging of a climate more supportive of creativity and innovation.Practical implications– Positive outcomes have significant implications for the enhancement of creativity and innovation through intrinsic motivation. This example has potential for other public service organisations.Originality/value– Simultaneous interventions across multiple levels are rare. That this has been achieved in a rigid bureaucratic environment public sector organisation adds to the unique value of this contribution.
A consumer definition of store convenience (finally)
Authors: Reimers Vaughan 
Published: May 2014

Purpose
– Despite an increasingly convenience-oriented society, very few empirical studies have identified convenience as a salient determinant of store patronage. Such atypical findings could be due to the way in which academics have defined store convenience. The purpose of this study is to empirically develop an alternative definition of store convenience.

Design/methodology/approach
– A household mail-out survey was used to identify the attributes consumers associate with store convenience.

Findings
– Empirical analysis provides strong support for the alternative definition, with respondents indicating that 25 of the test attributes serve as convenience attributes in the context of a department store.

Practical implications
– In spite of the many things a store manager can do to make their store more convenient, academic studies have recognised very few of these as convenience attributes. This study provides store managers with a list of 25 tools they have at their disposal to help save their customers' time and effort and help combat the internet threat.

Originality/value
– Comprising 25 attributes, the alternative definition represents a significant increase over any existing definition. The failure of existing definitions to incorporate so many of these attributes may explain why academic research has suggested that, in an era of convenience, convenience itself is a less-than-salient determinant of store patronage.
Which retail services are co-located?
Authors: Öner Özge , P. Larsson Johan 
Published: May 2014

Purpose– Which retail services are co-located in space? Is it possible to categorize retail stores of different kinds with respect to their location pattern? Acknowledging the spatial dependency between different and similar kinds of retailing activities, the aim of this paper is to find if and to what extent co-location is present in a retail market and what kind of retailing activities are co-located.Design/methodology/approach– The authors analyse the co-location of different types of retail stores in Sweden by using geo-coded data. The data they use allows them to pinpoint each establishment in Sweden down to a 250 by 250m square in space. First, they identify a measure of co-location for each retail service by utilizing pairwise correlations between the different retail service establishments with respect to the squares in which they are present. Later, by using the finest level of industrial categorization for all physical retailing activities (and limiting their geographical unit to the Stockholm metropolitan market), they perform factor analysis to nest these retailing activities under relevant categories based on their co-location pattern.Findings– In this analysis the authors obtain four major factors for the squares with retail stores, in which several kinds of retail activities are nested. These factors reveal a certain degree of location commonality for the markets in question.Originality/value– The authors' empirical design is based on a highly disaggregated spatial information and the methodology is novel in a sense that it has not been used to address a similar question. Rather than sampling, the authors use the total population, where they take all physical retailing activities into account to be able to draw a general picture for the co-location phenomena in the entire retail market.
New Zealand patients’ perceptions of chronic care delivery
Authors: Carryer Jenny , Doolan-Noble Fiona , Gauld Robin , Budge Claire 
Published: May 2014

Purpose– Care coordination for patients with chronic conditions is one aim of an integrated health care delivery system. The purpose of this paper is to compare findings from two separate New Zealand studies and discusses the implications of the results.Design/methodology/approach– The paper describes and discusses the use of Patient Assessment of Chronic Illness Care Measure in two different geographic areas of New Zealand and at different times.Findings– The studies suggest that, despite the time that has elapsed since government investment in care coordination for long-term conditions, there has been little change in the nature of service delivery from the patient perspective.Originality/value– The paper highlights the shortcomings of simply providing additional funding for care coordination, without built in accountabilities, no planned evaluation and no concerted focus on what the model of care should look like.
After pain comes joy: identity gaps in employees
'
minds
Authors: Park Jin Suk 
Published: May 2014

Purpose
– The purpose of this paper is to bridge the theory of organisational identity and the practice of HR management.

Design/methodology/approach
– This conceptual paper starts from the fundamental questions about employees
'
defining-self in workplaces. Specifically, this paper examines the organisational identity by adopting a process model of sensemaking which assumes a dynamic cycle between the sensebreaking and sensegiving activities. Based on this, this paper develops and provides a practical framework for HR practitioners and a theoretical implication for academic researchers.

Findings
– The author introduces the concept of identity gaps, a relatively under researched area in the social identity literature and HR management. Then, three types of identity gaps are identified: individual-individual gaps, organisational-organisational gaps, and individual-organisational gaps. Based on this categorization, this paper shows the matching HR practices for each type one by one.

Originality/value
– Today
'
s practices of HR seem to underestimate the importance of employees
'
activities of defining self-identities even though academic research on employees
'
identity is flourishing. By providing clear and structured framework for managing employee
'
s identity, this paper can bridge the theory of identity and the practice in HR management.
The mediating role of job content plateau on the relationship between work experience characteristics and early retirement and turnover intentions
Authors: Hofstetter Hila , Cohen Aaron 
Published: May 2014

Purpose– The study aims to elucidate the relationship between five work experiences or conditions (age-related stereotypes, perceived organizational support [POS], coworker support, career satisfaction, and reaching a job plateau) and two different organizational withdrawal intentions – early retirement and turnover – in light of trends to abolish or increase the mandatory retirement age in Israel and elsewhere in the Western world.Design/methodology/approach– The study is based on a survey of a heterogeneous age sample of 170 unionized employees working in medium-sized Israeli industrial firms.Findings– POS and perceived age stereotypes were negatively related to early retirement intentions and not to turnover intentions. Job plateau was found to be related to the other work-related variables, with the exception of coworker support, and also was found to be a strong mediator between these variables and employees ' turnover intentions, and a partial mediator between the variables and early retirement intentions.Practical implications– The study suggests a managerial focus on the person-job fit over time as a tool for reducing employees ' turnover intentions, and encouraging continued employee development as a way to reduce early retirement intentions.Originality/value– The study focuses on the potential role of correctable contextual characteristics in triggering withdrawal responses, in light of the aging of the workforce.
