How professionals can lead networks in the NHS
Authors: Malby Rebecca , Mervyn Kieran , Pirisi Luca 
Published: October 2013

Purpose
– The largest organisation in the western world, the UK National Health Service (NHS), might be best viewed as a network of interdependent organisations. However, the public has only recently begun to see it as a living network. Public reforms and financial crises have increased the need for professionals to innovate and improve their role. The overarching question is how this new clinical leadership can positively affect the functioning of the system and its performance. Therefore, the purpose of this paper is to clarify how leaders can be most effective in managing health networks.

Design/methodology/approach
– A pragmatic approach was taken because of the topical and strategic importance of networks and leadership in the current climate, and hence a need for greater understanding of this largely unknown phenomenon. A focus group interview with Organisational Development experts from the Centre for Innovation and Health Management (CIHM) at Leeds University Business School was followed by three scoping reviews and high-level follow-up conversations with CIHM members, network leaders from the NHS and third sectors.

Findings
– Issues that have emerged include: how networks are designed; which factors enhance its likelihood of success and predicate its failure; discussions of illuminating effective leadership.

Research limitations/implications
– The Stories of Effective Leadership Networks were provided by the network founders, who may have sought to emphasise the benefits (as opposed to downside) of their network. An ideal scenario would have been the inclusion of patients and carers and perhaps administrative staff to reduce bias.

Originality/value
– Considering the limited evidence base from the literature about medical leadership for network management, the involvement of network leaders and the ability to draw-upon CIHMs knowledge and expertise has been fundamental for determining lessons that may enhance the leadership function of the UK's health system network.
Leading with mind, heart, body and spirit
Authors: Gilbert Peter 
Published: October 2013

Purpose– The purpose of this paper is to consider the nature of leadership in the current context where the crisis in global capitalism seems to be encouraging a mechanistic approach to the management of healthcare. The paper urges an holistic leadership ethos to encourage an holistic approach to care and treatment.Design/methodology/approach– The paper utilises an extensive overview of the leadership literature, and also used practical examples of care and leadership practice.Findings– Care and capability need to be partners, but concern has been expressed at all levels of society that a reductionist model is being implemented in many caring professions.Practical implications– The implications for leadership are that one of the most vital current requirements is to encourage a spirit-filled leadership at all levels in the organisations that provide care.Originality/value– The paper addresses the issue that leadership can never be a purely intellectual or emotional activity, it must combine all aspects of the person in an holistic approach.
Hierarchical distance as a moderator of HRM practices on organizational performance
Authors: Triguero-Sánchez Rafael , C. Peña-Vinces Jesús , Sánchez-Apellániz Mercedes 
Published: October 2013

Purpose
– The purpose of this paper is to examine the moderator role of hierarchical distance (HD) in the relationship between human resources management (HRM) practices and organizational performance (OP, perceived/financial). To date there is no empirical evidence that demonstrates whether HD affects this relationship.

Design/methodology/approach
– These relationships are examined through an empirical study of 102 small- and medium-sized enterprises from Europe (Spain). Partial least squares structural equation modeling is used to test the moderator effect of HD.

Findings
– The results show that HD is a cultural dimension which moderates the relationship between HRM practices and OP. Furthermore, when OP is studied in relation to HRM practices, the use of perceived measures are considered more appropriate as these indicate the opinion of employees and managers regarding about OP.

Research limitations/implications
– The non-cross-sectional character of the paper.

Practical implications
– Organizations should consider HD when deciding the structure and application of their HR practices, since a lesser HD has positive effects on business results.

Originality/value
– Little attention has been paid to non-linear models, with particular reference to the inclusion of cultural dimensions – such organizational culture (i.e. HD) – in HRM models.
Integrating social sensors and pervasive services: approaches and perspectives
Authors: Rosi Alberto , Mamei Marco , Zambonelli Franco 
Published: October 2013

Purpose
– The key purpose of this paper is to overview the many issues related to the integration of social sensing and pervasive sensing in the support of adaptive context-aware services.

Design/methodology/approach
– From the analysis of existing proposals and prototypes, the authors found out that the process of integrating social and pervasive sensing can follow a limited number of approaches, which enables the authors to properly frame the proposals existing in the literature (and/or available as prototype infrastructures) according to a simple taxonomy, which is very useful to make the survey much more effective than a simple list of systems and proposals.

Findings
– The taxonomy shows that, when integrating social sensing with pervasive sensing, it is possible, at one extreme, to exploit social network as a mere source of information and have such information flow towards the infrastructure supporting the execution of pervasive computing services. At the other extreme, it is possible exploiting a social network as an infrastructure for the integration, by having data from pervasive devices flow towards social networks. In between the extremes, different means can consider to have social networks and pervasive infrastructures converge towards each other to enable the integration of social and pervasive sensing.

Originality/value
– Besides introducing the main concepts related to social sensing and framing the key approaches that can be undertaken to pursue the integration with traditional pervasive sensing, the authors go further discussing open issues and key research challenges behind their seamless integration.
XPath fragments on XML in columns
Authors: Pokorný Jaroslav 
Published: October 2013

Purpose
– This paper considers schemaless XML data stored in a column-oriented storage, particularly in C-store. Axes of the XPath language are studied and a design and analysis of algorithms for processing the XPath fragment XP{*, //, /} are described in detail. The paper aims to discuss these issues.

Design/methodology/approach
– A two-level model of C-store based on XML-enabled relational databases is supposed. The axes of XPath language in this environment have been studied by Cástková and Pokorný. The associated algorithms have been used for the implementation of the XPath fragment XP{*, //, /}.

Findings
– The main advantage of this approach is algorithms implementing axes evaluations that are mostly of logarithmic complexity in n, where n is the number of nodes of XML tree associated with an XML document. A low-level memory system enables the estimation of the number of two abstract operations providing an interface to an external memory. The algorithms developed are mostly of logarithmic complexity in n, where n is the number of nodes of XML tree associated with an XML document.

Originality/value
– The paper extends the approach of querying XML data stored in a column-oriented storage to the XPath fragment using only child and descendant axes and estimates the complexity of evaluating its queries.
An ontology update mechanism in IaaS service discovery system
Authors: Uchibayashi Toshihiro , Apduhan Bernady , Shiratori Norio 
Published: October 2013

Purpose
– Hybrid cloud computing is considered a viable and cost-effective approach to satisfy the inability of a private cloud to meet the user requirements. The information status of the selected public cloud service may change at runtime which should be reflected at the broker server database. This research illustrates a mechanism to assist the IaaS discovery system to assess the status change of the selected public cloud service and to update the broker server database. The paper aims to discuss these issues.

Design/methodology/approach
– A prototype was developed with the broker server as the main component in the service discovery system containing the status information of the selected public cloud service. The merge-ontology and patch-update methods were proposed, the processing cost details of each were measured, and the methods were evaluated.

Findings
– Experimental results showed that in the merge update, the merging process incurred much longer time than its required communication, contributing to long overall time. Relatively, the patch update method incurred much less time than its counterpart.

Research limitations/implications
– The proposed mechanism is experimental with some ideal assumptions, and so further work in real conditions is needed for its improvement.

Originality/value
– This research is believed to be the first proposal to investigate ontology merge/patch methods to support ontology update in the broker server database of a hybrid cloud and will serve as a reference to researchers in the field.
Evaluation of T-stress for a hypocycloid hole in an infinite plate
Authors: Chen Y.Z. 
Published: October 2013

Purpose
– This paper is devoted to the evaluation of the T-stress for a hypocycloid hole in an infinite plate. The remote tractions are applied for the infinite plate containing the hypocycloid hole. After using the conformal mapping, an elasticity solution is obtained, and the T-stress at the cusp tip can be abstracted from this solution. The paper aims to discuss these issues.

Design/methodology/approach
– Conformal mapping technique is used for solving the T-stress problem for a hypocycloid cusp hole problem.

Findings
– The present study proves that the cusp configuration has a significant influence to the value of T-stress at cusp crack tip.

Originality/value
– A closed form solution for the T-stress in cusp crack is first obtained in the submission.
The effect of exogenous information signal strength on herding
Authors: F. Luchtenberg Kimberly , Joseph Seiler Michael 
Published: October 2013

Purpose– In the controlled environment of a professional business seminar, the paper collects data on the willingness of participants to strategically default on a mortgage that is underwater by varying degrees. By providing the participants with fabricated exogenous strong and weak information signals, the paper is able to examine the effect of the signals on their responses. The purpose of this paper is to find evidence suggesting that gender, moral opposition, level of susceptibility to information, and information signal strength influence herding in business professionals.Design/methodology/approach– The paper adopts the Hirshleifer and Hong Teoh (2003) definition of herding as “any behavior similarity/dissimilarity brought about by the interaction of individuals.” In the controlled environment of a professional business seminar, the paper collects data on the willingness of participants to strategically default on a mortgage that is underwater by varying degrees. By providing the participants with fabricated exogenous strong and weak information signals, the paper is able to examine the effect of the signals on their responses.Findings– The major contribution is that the paper finds evidence suggesting that signal strength does indeed matter. The paper finds that a weak signal is more likely to produce herding when respondents answer questions relating their own decisions and strong signals produce more herding when respondents provide advice to others. The paper also finds that women are less likely to herd and people who report they are susceptible to information influences are more likely to herd. Not surprisingly, participants who are morally opposed to strategic default are less likely to herd in most scenarios.Originality/value– No other study of which the authors are aware looks specifically at signal strength in a financial setting or uses a sample of business professionals to examine herding of a financial nature.
An algorithm for extracting STL model from axisymmetric ring element mesh
Authors: Tian Zhongke 
Published: October 2013

Purpose
– The purpose of this paper is to use rapid prototyping (RP) technology to build physical models based on axisymmetric finite element (FE) simulation deformation results. To this end, an algorithm which extracts stereolithography (STL) model from axisymmetric ring element mesh is developed and realized by MATLAB programming.

Design/methodology/approach
– The algorithm first identifies boundary element edges, which compose the contour(s) of an axisymmetric ring FE mesh. Then, the identified contour edges are around the symmetry axis revolved a specific angle, at certain intervals according to certain approximate criterion, to generate new nodes to form a group of oriented triangles whose normal vectors conform to the right-handed rule. Finally, a completely closed STL model is obtained by necessary triangulation processing and rotation mapping based on original mesh.

Findings
– It is validated that the extracted STL model is sound and the proposed algorithm is feasible, right and characterized by linear time complexity for extracting STL model from either triangular, quadrilateral, or mixed triangular/quadrilateral axisymmetric mesh.

Research limitations/implications
– Color is important for expressing FE simulation results, which is not involved in STL model. Among the alternative data file formats, VRML representation is an applicable one that is complimentary to existing RP processes and suitable for color 3D printing. Based on the current work, coloring VRML model could be extracted from axisymmetric FE simulation results conveniently.

Originality/value
– The study of this paper provides a RP-based materialized mode to characterize axisymmetric FE simulation deformation results, which is more intuitive and visible than the computer graphics-based visualization.
Thickening freeform surfaces for solid fabrication
Authors: C.L. Wang Charlie , Chen Yong 
Published: October 2013

Purpose
– Given an intersection-free mesh surface S, the paper introduces a method to thicken S into a solid H located at one side of S. By such a surface-to-solid conversion operation, industrial users are able to fabricate a designed (or reconstructed) surface by rapid prototyping.

Design/methodology/approach
– The paper first investigates an implicit representation of the thickened solid H according to an extension of signed distance function. After that, a partial surface reconstruction algorithm is proposed to generate the boundary surface of H, which retains the given surface S on the resultant surface.

Findings
– Experimental tests show that the thickening results generated by the method give nearly uniform thickness and meanwhile do not present shape approximation error at the region of input surface S. These two good properties are important to the industrial applications of solid fabrication.

Research limitations/implications
– The input polygonal model is assumed to be intersection-free, where models containing self-intersection will lead to invalid thickening results.

Originality/value
– A novel robust operation is to convert a freeform open surface into a solid by introducing no shape approximation error. A new implicit function gives a compact mathematical representation, which can easily handle the topological change on the thickened solids. A new polygonization algorithm generates faces for the boundary of thickened solid meanwhile retaining faces on the input open mesh.

Design/methodology/approach
– Establishing of assumptions for the impeller design process based on the HTC characteristics analysis, creation of the virtual solid model of HTC impellers, fabrication of HTC impellers by using the SLS method, investigation of the performance of HTC with fabricated impellers by using a test rig.

Findings
– The test results show that the SLS method can be successfully used for the fabrication of HTC impellers with 3D and flat blades.

Research limitations/implications
– The method application is limited to small diameters of HTC impellers depending on working area dimensions of SLS machine.

Practical implications
– The method can decrease the time and cost of fabrication of HTC impellers by using the SLS method.

Originality/value
– The application of the SLS method for fabrication of HTC impellers with 3D and flat blades.
Influence of oxidation on the cracks of DZ125L nickel-based superalloy thin-walled parts in laser metal direct forming
Authors: He Bin , Li Dichen , Zhang Anfeng , Lu Zhongliang , Ge Jiangbo , Tat Khoa Doan 
Published: October 2013

Purpose
– The purpose of this paper is to investigate the influence of the oxidation on the cracks of DZ125L nickel-based superalloy thin-walled parts in laser metal direct forming (LMDF).

Design/methodology/approach
– Thin-walled cylinders were fabricated in protective atmosphere with different oxygen contents in order to reveal the influence of oxidation on the morphology of cracks. The influence of oxidation on the cracks was investigated in detail by measuring the wall thicknesses of cylinders, the residual stress in the top surface of the cylinders and the composition of the cracks. Finally, the validity of the results was verified by fabricating a thin-walled turbine blade in protective atmosphere.

Findings
– The experimental results showed that wall thickness fluctuation of cylinders, unequal residual stress distribution of cylinders and the oxides in the crack were all the critical factors which led to crack of DZ125L thin-walled parts. Thin-walled turbine blades with no cracks can be fabricated when the oxygen content was about less than 150 ppm in protective atmosphere.

Research limitations/implications
– The appropriate oxygen content in protective atmosphere is helpful for fabricating thin-walled parts of nickel-based superalloy like DZ125L, and the results can show what will happen at different oxygen levels. Moreover, the results show that the cracks can be eliminated as the oxygen content reduce to less than 150 ppm rather less than 10 ppm or even less, which can reduce the cost of protective gas as forming thin-walled parts of nickel-based superalloy such as DZ125L.

Practical implications
– The appropriate oxygen content in protective atmosphere is helpful for fabricating thin-walled parts of nickel-based superalloy like DZ125L. However, when heavy solid parts of some other material other than DZ125L were fabricated, the oxygen content of less than 150 ppm may be not suitable.

Originality/value
– The influence of oxidation on the cracks of DZ125L thin-walled parts in LMDF was investigated in detail, and a DZ125L thin-walled turbine blade with no cracks was fabricated by adjusting the oxygen content in protective atmosphere.
Social enterprise in the development agenda. Opening a new road map or just a new vehicle to travel the same route?
Authors: Carlos Perez de Mendiguren Castresana Juan 
Published: October 2013

Purpose– The paper aims to analyse the narrative that promotes “social enterprise” and “social entrepreneurship” as innovative ways of obtaining economic growth, social development and environmental sustainability for all people on the planet. It assesses their influence on current debates on the development agenda and explores some critical issues that can contribute to re-politicizing the agenda beyond the Millennium Development Goals (MGD).Design/methodology/approach– Using a conceptual approach, the article identifies the discourses on which the central elements of the dominant discourse on “inclusive business” in development rest, and the empirical evidence on the results obtained from this focus. It subsequently employs different critical theoretical approaches to reformulate some of the debates and objectives that would make it possible to re-orientate the agenda from a perspective of social justice and sustainability.Findings– As it is posed, the idea of “inclusive business” for development does enable advance in a direction that would revise the premises on development, include the normative dimension in debates, and present a new evaluative space for economic activity from the perspective of equity, social justice and human development. Making the best use of this opportunity involves deepening the proposals of the solidarity economy in continuous dialogue with other emancipatory experiences and currents of critical thought.Originality/value– The paper questions some central elements of the orthodox conception of inclusive business and introduces analytical perspectives that are not commonly found in the literature on the topic.
Continuous reconfiguration in the transient advantage economy
Authors: Gunther McGrath Rita 
Published: October 2013

Purpose
– The author identified a set of companies that have figured out how to cope, even to thrive, within the new transient advantage economy and explains how they did it.

Design/methodology/approach
– Her research team analyzed nearly 5,000 companies. Of that whole population, only ten companies were able to grow their net income by at least 5 percent a year for ten years in a row. These ten “outliers” have out-performed competitors while adapting to rapidly changing market forces.

Findings
– Organizations that have mastered transient-advantage environments have learned to continually free up resources from old advantages in order to fund the development of new ones. Additionally, innovation is continuous, mainstream and part of everyone's job.

Research limitations/implications
– The 5,000 companies analyzed included every publicly traded firm on any stock exchange with a market capitalization of over $1 billion. The article studies the practices of the ten most successful over ten years.

Practical implications
– The most successful firms, over the entire study period, had no dramatic downsizings, restructurings or sell-offs.

Originality/value
– The author found that the key leadership and management challenge is maintaining an organizational system that can manage the complementary forces of innovation and stability.
