First and foremost, physicians: the clinical versus leadership identities of physician leaders
Authors: Quinn Joann Farrell , Perelli Sheri 
Published: June 2016

Purpose– Physicians are commonly promoted into administrative and managerial roles in US hospitals on the basis of clinical expertise and often lack the skills, training or inclination to lead. Several studies have sought to identify factors associated with effective physician leadership, yet we know little about how physician leaders themselves construe their roles. The paper aims to discuss these issues.Design/methodology/approach– Phenomenological interviews were performed with 25 physicians at three organizational levels with physicians affiliated or employed by four hospitals within one health care organization in the USA between August and September 2010. A rigorous comparative methodology of data collection and analysis was employed, including the construction of analytic codes for the data and its categorization based on emergent ideas and themes that are not preconceived and logically deduced hypotheses, which is characteristic of grounded theory.Findings– These interviews reveal differences in how part- vs full-time physician leaders understand and value leadership roles vs clinical roles, claim leadership status, and identify as physician leaders on individual, relational and organizational basis.Research limitations/implications– Although the physicians in the sample were affiliated with four community hospitals, all of them were part of a single not-for-profit health care system in one geographical locale.Practical implications– These findings may be of interest to hospital administrators and boards seeking deeper commitment and higher performance from physician leaders, as well as assist physicians in transitioning into a leadership role.Social implications– This work points to a broader and more fundamental need – a modified mindset about the nature and value of physician leadership.Originality/value– This study is unique in the exploration of the nature of physician leadership from the perspective of the physician on an individual, peer and organizational level in the creation of their own leadership identity.
Significance of scientific evidence in organizing care processes
Authors: Hasson Henna , Blomberg Staffan , Dunér Anna , Sarvimäki Anneli 
Published: June 2016

Purpose
– The purpose of this paper is to analyze how staff and managers in health and social care organizations use scientific evidence when making decisions about the organization of care practices.

Design/methodology/approach
– Document analysis and repeated interviews (2008-2010) with staff (n=39) and managers (n=26) in health and social care organizations. The respondents were involved in a randomized controlled study about testing a continuum of care model for older people.

Findings
– Scientific evidence had no practical function in the social care organization, while it was a prioritized source of information in the health care organization. This meant that the decision making regarding care practices was different in these organizations. Social care tended to rely on ad hoc practice-based information and political decisions when organizing care, while health care to some extent also relied in an unreflected manner on the scientific knowledge.

Originality/value
– The study illustrates several difficulties that might occur when managers and staff try to consider scientific evidence when making complicated decisions about care practices.
Patient, co-producer and consumer in one person
Authors: Ewert Benjamin 
Published: June 2016

Purpose– Integrated health care lacks a theoretical concept of the user figure that is appropriate to reflect users’ various claims and multi-dimensional interrelations in the care process. The paper aims to discuss this issue.Design/methodology/approach– Key goals of integrated health care, such as a continuity of care, seamless services and better health outcomes depend strongly on users’ capabilities to engage themselves in the care process. These goals are hardly reachable if integrated health care schemes operate with a one-dimensional understanding of users’ identity.Findings– The suggested concept of users’ identity facets suggests that users draw from different sources while receiving integrated health care. Thus, users are patients, co-producers, citizens, consumers and community members in one person and at the same time. Each facet of the user identity gains or loses relevance depending on health care contexts, health statuses, personal values and the design of service arrangements. As demonstrated by the example of disease management programmes (DMPs), care schemes for chronically ill persons, users have to apply different facets of their identities in order to benefit best from service provision. Moreover, addressing users’ identity may facilitate the extent of integration in DMPs.Originality/value– Integrated health care schemes are challenged to invent strategies that facilitate and support coherence among users’ diverse identities in the process of service provision. Lessons could be learned from small-scale and localized integrated health care networks.

Authors: Yuvaraj Mayank , Maurya Ambrish Kumar 
Published: June 2016

Purpose
This paper aims to introduce the concept of open-source hardware to the library professionals and gives a brief of the outlook of its current and potential application in libraries

Design/methodology/approach
The paper is based on a literature review.

Findings
Open source already aids libraries and has great potential but is hobbled by its intrinsically technical appeal.

Originality/value
The paper makes first observation towards the concept of open-source hardware with a slant towards librarianship.
Hosting an Appy Hour in the library
Authors: Loughmiller Lucas 
Published: June 2016

Purpose
This paper aims to give a detailed description of tablets (specifically iPads) in the author’s school district and the Appy Hours they offered to support instructional use.

Design/methodology/approach
Collaborating with other districts and staff, the author developed Appy Hours to give teachers and librarians a chance to showcase how to use the devices in their schools, classrooms and libraries.

Findings
Offering Appy Hours in the libraries was an easy fit for collaboration and idea sharing. Rotating them between buildings made them more appealing to teachers, and having classroom teachers and librarians present made them more appealing to other staff members.

Originality/value
Appy Hours are not an entirely new concept. The author’s district used them effectively to spread new ideas and concepts through the libraries.
Stakeholders’ interest in sustainability assurance process
Authors: Bepari Md Khokan , Mollik Abu Taher 
Published: June 2016

PurposeThis paper aims to critically analyse the content of the assurance statements of corporate sustainability reports to examine the degree to which assurance statements enhance and uphold organisational transparency and accountability to stakeholders.Design/methodology/approachThis framework of content analysis draws on a research instrument developed by O’Dwyer and Owen (2005), as well as the most recent assurance guidelines (Global Reporting Initiative) and standards AA1000AS, 2008 and ISAE 3000.FindingsDue to the lack of stakeholders’ engagement in the assurance process, due to the scope limitation placed on the assurance engagement and due to the reluctance of the assuror to address the assurance statements to the stakeholders groups, sustainability assurance practice cannot be considered as the accountability enabler. With persistent focus on internal systems, process, data generation and data capture, assurance practice is serving more as an internal control tool than as a social accounting/auditing instrument.Research limitations/implicationsA single country context is studied. However, to the extent that assurances are conducted using common sets of assurance standards and guidelines, there is external validity of the findings.Practical implicationsDespite the institutional initiatives by the global and local institutions regarding social and environmental sustainability reporting and assurance, the assurance practice has not yet emerged as a tool of social accountability.Originality/valueThis study provides a comprehensive and up-to-date empirical assessment of the degree to which the sustainability assurance practice encompasses the issue of stakeholders’ interests and forms the potential basis for policy implications to the assurance practice and to the assurance standard setting process.
Contextual factors and lean production implementation in the Brazilian automotive supply chain
Authors: Marodin Giuliano Almeida , Frank Alejandro Germán , Tortorella Guilherme Luz , Saurin Tarcisio Abreu 
Published: June 2016

Purpose
This paper aims to understand the patterns of lean production implementation, and the relationship between three context factors (i.e. firm size, positions within the supply chain and time length of the lean initiative) and the adoption of lean production practices in firms of the automotive supply chain in Brazil.

Design/methodology/approach
The authors collected data from 65 companies of the automotive supply chain in Brazil. For data analysis, first a cluster analysis was performed to identify common characteristics in the companies’ context factors when considering patterns of lean implementation. Then, multivariate analysis of variance was used to investigate the differences between the context factors and the degree of use of lean practices.

Findings
High lean adopters had better performance than low lean adopters in terms of lead time, inventory and turnover. Firms at the first and second tier of the automotive supply chain were “leaner” than firms at the third tier. Large-sized firms were more likely to have a higher degree of use of lean practices than medium and smaller ones. Some, but not all, lean practices followed these patterns. Results also showed that some lean practices were most commonly adopted at the beginning of the lean journey, whereas others took more time to mature.

Originality/value
This paper demonstrated how lean practices were implemented at different positions within the supply chain, and the patterns of implementation often followed. It also considers lean in the context of developing countries such as Brazil.
Dynamic development and execution of closed-loop supply chains: a natural resource-based view
Authors: Miemczyk Joe , Howard Mickey , Johnsen Thomas E. 
Published: June 2016

PurposeThis paper aims to reflect on recent closed-loop supply chain (CLSC) practices using a natural resource-based view (NRBV) and dynamic capabilities (DC) perspective.Design/methodology/approachTwo empirical case studies of CLSC exemplars are used to discuss the theoretical relevance of these views.FindingsThe paper shows how strategic resources help companies in two sectors achieve successful CLSC designs. Strategic supply chain collaboration is an important success factor but also presents a number of challenges. The NRBV is used to explain the importance of new resources in technology, knowledge and relationships and stresses the role of DCs to constantly address changes in the business environment to renew these strategic resources.Research limitations/implicationsThis research elaborates on NRBV theory related to CLSCs and reinforces the inclusion of DCs. It specifies the application of NRBV in the context of textiles and carpet manufacture and highlights the inherent conflicts in seeking value while moving towards sustainable development.Practical implicationsInvestments in technical and operational resources are required to create CLSCs. Pure closed-loop applications are impractical, requiring relationships with multiple external partners to obtain supply and demand for recycled products.Social implicationsCLSCs may provide opportunities for social enterprises or third sector organizations collaborating with manufacturers.Originality/valueThis paper provides insights into the constituent resources needed for successful CLSCs. It also helps move CLSC research from a tactical logistics problem to a problem of strategic resources and relational capabilities: what we term “dynamic supply chain execution”. This paper develops a framework for transitioning towards CLSCs, underlining the importance of co-development and forging new relationships through commitment to supply chain redesign, co-evolution with customers and suppliers and control of supply chain activities.
Business lending and bank profitability in the UK
Authors: Ekpu Victor , Paloni Alberto 
Published: June 2016

Purpose
The purpose of this paper is to investigate the importance of business lending as a source of bank profits in the UK banking system. The paper also examines whether the profitability of business lending is mostly driven by heterogeneous characteristics of individual banks or whether it is affected by systematic characteristics such as bank size and ownership structure.

Design/methodology/approach
The study uses bank level data from BankScope for a total sample of 83 UK banks and building societies. The period under consideration extends from 2005 to 2009. Econometric estimation is by panel fixed effects.

Findings
Our empirical results show that business lending is a statistically significant determinant of bank profits. However, this average effect masks important systematic differences among banks. In particular, we find strong size effects: the profitability of business lending is considerable for small banks but negligible for large banks. In contrast, we could not detect any ownership effects for domestic and foreign banks. These findings persist when the occurrence of the financial crisis is accounted for.

Research limitations/implications
Interestingly, our study relates these findings to the process of financialisation. Yet, the extent of the latter and its impact on various groups of banks (i.e. large, small, domestic and foreign banks) have not been examined. Further research in this area would make an important contribution to the literature.

Practical implications
Our findings suggest that business lending is not a driving factor of profitability for large banks. One possible policy implication – which may be of interest especially to regulators and policy makers – is that capital injections into the larger banks per se are unlikely to lead to an expansion of credit to business.

Originality/value
There is very little research in the literature on the questions addressed in this paper, especially for the UK banking system. Moreover, the process of financialisation, which motivates the enquiry of this paper, is a growing area of research. Thus, the contribution of this paper is twofold.
Assessing foreign funds geographical focus timing skill
Authors: Rodríguez Javier , Romero Herminio 
Published: June 2016

Purpose
This paper aims to study the market timing skill of USA-based foreign open-end mutual funds in their geographical focus market.

Design/methodology/approach
The authors use daily fund data and two multi-factor extensions of the Treynor-Mazuy (1966) and Henriksson-Merton (1981) timing models to measure US-based foreign funds’ market timing skill during 1999 to 2010. In particular, the authors study fund managers’ skill to time their geographical focus market.

Findings
The authors report that, in general, foreign funds do not accurately time their geographical focus market. However, during January 2008 to December 2010, the sub period that includes the 2008 global financial crisis, most foreign funds in this sample not only focused on their domestic market, the USA, but also demonstrated statistically significant, good timing skill.

Originality/value
Although US-based foreign funds’ market-timing skill is not an unexplored topic, this study is the first to consider these funds’ skill to time their geographical focus market, a skill that has been studied in the context of hedge funds.
Generalized poroelasticity framework for micro‐inhomogeneous rocks
Authors: Müller Tobias M. , Sahay Pratap N. 
Published: June 2016

ABSTRACTPoroelastic modelling of micro‐inhomogeneous rocks is of interest for applications in rock physics and geomechanics. Laboratory measurements from both communities indicate that the Biot poroelasticity framework is not adequate. For the case of a macroscopically homogeneous and isotropic rock, we present the most general poroelasticity framework within the scope of equilibrium thermodynamics that is able to capture the effects of micro‐inhomogeneities in a natural way. Within this generalized poroelasticity framework, the concept of micro‐inhomogeneity is generically related to partial localization of the deformational potential energy either in the solid phase, including the interfacial region or in the fluid phase. The former case can occur in the presence of surface roughness or multi‐mineralic frame and the latter case can be related to suspended particles residing in the fluid phase. A measure for micro‐inhomogeneity is the coefficient that governs the effective pressure dependence of porosity changes as described by the porosity perturbation equation of this framework. It can be therefore equivalently interpreted as porosity effective pressure coefficient or as micro‐inhomogeneity parameter. We show how this parameter and the other poroelastic constants embedded in this framework can be expressed in terms of experimentally accessible poroelastic constants.
Experimental mechanical compaction of sands and sand–clay mixtures: a study to investigate evolution of rock properties with full control on mineralogy and rock texture
Authors: Koochak Zadeh Mohammad , Mondol Nazmul Haque , Jahren Jens 
Published: June 2016

ABSTRACTDevelopment of rock physical properties in well‐sorted and poorly‐sorted unconsolidated mono‐quartz sands and sand–clay mixtures as a function of effective stress in both dry and brine‐saturated conditions is assessed in this study. The tested samples were prepared with full control on their mineralogy, grain size, grain shape, sorting, and fabric. The experiments were performed in a high‐stress uniaxial oedometer up to a maximum of 30 MPa vertical effective stress. Sand–clay samples were a mixture of sand grains and clay particles (kaolinite or smectite) in different proportions. The maximum clay volume fraction used in the experiments was at most 30%. The initial bulk density of the tested sand‐dominated samples was adjusted to be close to the maximum index density expected for natural sediments (sand–clay mixtures) during deposition.In pure sand samples, finer grained sand show higher initial porosity than relatively coarser grained sands. Moreover, sand–clay mixtures have lower initial porosity than pure sands. Porosity decreases as a function of increasing clay content. The poorly‐sorted sand samples are less compaction prone than the well‐sorted sand samples. Among well‐sorted sand samples, coarser grained sands are more compressible than finer grained sands. At a given effective stress level, sand–clay mixtures are more compaction prone compared with their sand component alone. Pure sands and clay‐poor sand–clay mixtures (either sand–kaolinite or sand–smectite) show almost the same degree of compaction when tested in both dry and brine‐saturated conditions. In contrast, clay‐rich sand–kaolinite and sand–smectite mixtures (clay volume >20%) are significantly more compact in brine‐saturated condition. The Vp values of brine‐saturated sand–kaolinite mixtures shows a positive correlation with the kaolinite content, whereas Vp starts to decrease substantially when the volume fraction of smectite exceeds 10% of the whole sand–smectite samples.Saturated bulk moduli estimated by Gassmann's fluid substitution agree with measurements for brine‐saturated clay‐poor sand samples. However, the model does not yield proper predictions for sand–clay samples containing 20% clay volume and above, particularly when the clay is mainly smectite. The acoustic and physical properties derived from experimental compaction of pure sands and sand–clay mixtures show a good agreement with rock properties derived from well logs of mechanically compacted pure sands and shaly sands in progressively subsided basins such as Viking Graben in the North Sea. Thus, the outcome of this study can provide reliable constraints for rock physical properties of sands and shaly sands within the mechanical compaction domain and contribute to improved basin modelling and identification of hydrocarbon presence, overconsolidation, and/or undercompaction.
Static and dynamic pressure sensitivity anisotropy of a calcareous shale
Authors: Ong Oliver N. , Schmitt Douglas R. , Kofman Randolph S. , Haug Kristine 
Published: June 2016

ABSTRACTOptimizing the productivity of nonconventional, low‐permeability “shale” reservoirs requires detailed knowledge of the mechanical properties of such materials. These rocks' elastic anisotropy is acknowledged but usually ignored due to difficulties in obtaining such information. Here we study in detail the dynamic and static elastic properties of a suite of calcareous mudstones from the nonconventional Duvernay reservoir of Alberta, Canada. The complete set of transversely isotropic elastic constants is obtained from strategically oriented ultrasonic transducers to confining pressures of 90 MPa. Wave speed anisotropies of up to 35% are observed at even the highest confining pressures. Furthermore, the stress sensitivity of the wave speeds, and hence moduli, is itself highly dependent on direction with speeds taken perpendicular to the bedding plane being highly nonlinearly dependent on pressure, whereas those along the bedding plane show, unexpectedly, nearly no pressure dependence. These observations are in qualitative agreement with the preferentially oriented porosity and minerals seen in scanning electron microscope images. These results may be significant to the interpretation of sonic logs and azimuthal amplitude versus offset for principal stress directions, for the concentration of stress within such formations, and for estimation of static engineering moduli from sonic log wave speeds.
