Catastrophizing and pain-related fear predict failure to maintain treatment gains following participation in a pain rehabilitation program
Authors: Moore Emily , Thibault Pascal , Adams Heather , Sullivan Michael J.L. 
Published: September 2016

Abstract
The present study explored whether pain-related psychosocial risk factors played a role in determining whether treatment gains were maintained following participation in a rehabilitation intervention for musculoskeletal injury. The study sample consisted of 310 individuals (163 women, 147 men) with work-related musculoskeletal conditions who were enrolled in a physical rehabilitation program. Measures of pain severity, pain catastrophizing and pain-related fear were completed at the time of admission and at the time of discharge. Pain severity was assessed again at 1-year postdischarge. Participants were classified as “recovered” if they showed a decrease in pain of at least 2 points and rated their pain at discharge as less than 4/10. Recovered participants were considered to have failed to maintain treatment gains if their pain ratings increased by at least 2 points from discharge assessment to 1-year follow-up, and they rated their pain as 4/10 or greater at 1-year follow-up. The results of a logistic regression revealed that participants with high posttreatment scores on measures of catastrophizing and fear of pain were at increased risk of failing to maintain treatment gains. The findings suggest that unless end-of-treatment scores on catastrophizing and fear of pain fall below the risk range, treatment-related reductions in pain severity may not be maintained in the long term. The clinical and theoretical implications of the findings are discussed.
Design of Vaccine Trials during Outbreaks with and without a Delayed Vaccination Comparator
Authors: Dean Natalie E. , Halloran M. Elizabeth , Longini Ira M. 
Published: September 2016

AbstractConducting vaccine efficacy trials during outbreaks of emerging pathogens poses particular challenges. The ‘Ebola ça suffit’ trial in Guinea used a novel ring vaccination cluster randomized design to target populations at highest risk of infection. Another key feature of the trial was the use of a delayed vaccination arm as a comparator, in which clusters were randomized to immediate vaccination or vaccination 21 days later. This approach, chosen to improve ethical acceptability of the trial, complicates the statistical analysis as participants in the comparison arm are eventually protected by vaccine. Furthermore, for infectious diseases, we observe time of illness onset and not time of infection, and we may not know the time required for the vaccinee to develop a protective immune response. As a result, including events observed shortly after vaccination may bias the per protocol estimate of vaccine efficacy. We provide a framework for approximating the bias and power of any given per protocol analysis period as functions of the background infection hazard rate, disease incubation period, and vaccine immune response. We use this framework to provide recommendations for designing standard vaccine efficacy trials and trials with a delayed vaccination comparator. Briefly, narrower analysis periods within the correct window can minimize or eliminate bias but may suffer from reduced power. Designs should be reasonably robust to misspecification of the incubation period and time to develop a vaccine immune response.
Assessing data quality in citizen science (preprint)
Authors: Kosmala Margaret , Wiggins Andrea , Swanson Alexandra , Simmons Brooke 
Published: September 2016

AbstractEcological and environmental citizen science projects have enormous potential to advance science, influence policy, and guide resource management by producing datasets that are otherwise infeasible to generate. This potential can only be realized, though, if the datasets are of high quality. While scientists are often skeptical of the ability of unpaid volunteers to produce accurate datasets, a growing body of publications clearly shows that diverse types of citizen science projects can produce data with accuracy equal to or surpassing that of professionals. Successful projects rely on a suite of methods to boost data accuracy and account for bias, including iterative project development, volunteer training and testing, expert validation, replication across volunteers, and statistical modeling of systematic error. Each citizen science dataset should therefore be judged individually, according to project design and application, rather than assumed to be substandard simply because volunteers generated it.
Exploring participatory scenario and storyline building for sustainable urban futures – the case of China in 2050
Authors: Bina Olivia , Ricci Andrea 
Published: September 2016

Purpose
Drawing on a EU-funded research project on urbanisation in China and Europe (URBACHINA), the purpose of this inquiry is to explore the potential of foresight – through visionary scenarios and related participatory processes – in promoting learning and sustainable futures in China’s centrally planned context. Our research explores the use of backcasting, of Donella Meadows’ “levers” and Paul Raskin’s “proximate-ultimate drivers” and of archetypal worldviews to further our understanding of how we think about the future, and of the tension between transition scenarios and transformative, paradigmatic or deep change.

Design/methodology/approach
A review of recent foresight studies and literature provides an overview of the latest approaches: in particular the methods, scope, process, level of participation, themes discussed and wild cards considered. Building on this, the inquiry designs and implements a participatory, normative and qualitative scenario building to explore sustainable urban futures for China, adapting the elements of Joseph Voros’ basic foresight process to include a total of nine steps, with five workshops, two international surveys, an adapted backcasting step and internal consistency mechanisms.

Findings
The combination of a participatory iterative process with normative approaches to envisioning, helped question assumptions and deeply ingrained development models, as well as the narrow space for “alternatives” resulting from China’s centralised, top-down planning and decision-making. The experience confirms the power of scenario/storyline building in helping reflect and question strategic policy choices and enrich urban policy debates. The process successfully proposed a number of steps that ensured triangulation of the envisioning outcomes and additional learning also through backcasting. Finally, the research shows a clear link between the development of scenarios space, the debate on transition and transformative futures and archetypal worldviews, which were shown to be stable even after decades.

Originality/value
The URBACHINA approach to the specific challenge of sustainable urbanisation in China applies a strong normative component combined to more locally accepted exploratory methods and introduces a participatory approach to all key stages of scenario building. This represents an innovative contribution to the country’s foresight practice and the results help Chinese decision makers to reflect on the wider sustainability implications of their urban strategy. The inquiry deepens our understanding of the use of proximate and ultimate drivers of change and of the tension between transition and transformation pathways to our future.
Global food security: assessing trends in view of guiding future EU policies
Authors: Maggio Albino , Van Criekinge Tine , Malingreau Jean-Paul 
Published: September 2016

Purpose
A foresight process was put in place to examine potential developments that can affect the world food situation in 2030 to identify the most useful areas for European Union (EU) policy intervention.

Design/methodology/approach
Four interactive workshops involving over 100 experts were organised. The structure of the foresight was designed based on the following five objectives: envision the future of food systems, agree on the most crucial drivers of change affecting food security, reach a consensus on a likely vision for 2030, challenge this vision and analyse current policies and policy needs in terms of responsiveness and resilience to food security future challenges.

Findings
The study contains four key messages accompanied by several related policy recommendations for the immediate and medium term to enable the EU to contribute to achieving food security by 2030. These refer to the transformation of agriculture production systems, the enabling environment, trends in production and consumption and demand-driven food systems as important determinants of sustainable food security. The study recommends a stronger coherence and coordination between different EU policies impacting food security. The development of urban areas is an overlooked challenge for food security as well as the contribution of trade and demand-side dynamics.

Originality/value
This is one of the very few attempts to look at food security with a system approach. A new paradigm shift is proposed: securing “regular” access to adequate food for the majority of the 8-9 billion people who will live on earth in the period 2030-2050, while addressing the food insecurity of a fraction of that total, is how a future European food security policy should be approached.
Leapfrogging potential for sustainable energy transition in Serbia
Authors: Hakala Emma Sofia , Bjelic Ilija Batas 
Published: September 2016

Purpose
This paper aims to look at the dilemma of promoting sustainable energy transition in post-socialist countries while containing social and economic implications, focusing on the case of Serbia. The aim is to analyse Serbian energy status taking into account historical factors, to analyse barriers that are hindering transition and to identify leapfrogging potential for the sustainable energy development of the country.

Design/methodology/approach
Energy transition and leapfrogging potential have been qualified and quantified by indicators, the own calculations and policy analysis to identify barriers to sustainable energy.

Findings
The country has vast potential for leapfrogging in energy transition, yet continues the gradualist approach based on several policy barriers to the process. The analysis shows six barriers related to low energy price, high energy intensity, prioritization of energy security, inadequacy of utilization of renewable sources, lack of policy coherence and dependency on external funding. However, these barriers could be overcome with an energy policy emphasizing leapfrogging potential. As is pointed out in the conclusion, this should be based on the difference between EU-28 average indicators, discrepancy between use and availability of renewable energy, potential for regional cooperation in the energy sector and under-used skills and participation.

Originality/value
The paper discusses energy transition in its historical context, arguing that it has to be considered as comprehensively with societal implications and effects, thus creating useful knowledge for other post-socialist countries in current and future transitions.
Nanook of the North (USA, 1922/1947/1976/1998) and film exhibition in the classical silent era
Authors: Skare Roswitha 
Published: September 2016

Purpose
The purpose of this paper is to provide a discussion on whether more traditional documents like a film of the classical silent era can be discussed as an unbounded document.

Design/methodology/approach
By taking Gérard Genette’s concept of the paratext as point of departure and focussing on the exhibition of Nanook of the North during the silent era, the paper discusses elements neglected in most of the academic writings about the film, thereby illustrating the highly problematic notion of film as one original or authentic document that comes as a repeatable unit with clear borders.

Findings
More a “one-time performance” (Hansen, 1991, p. 93) than identical repetition of the film is one argument for talking about a document unbounded. Genette’s concept of the paratext provides a tool to handle the fluid character of these performances and makes us conscious about the complexity of elements both outside and inside the document and on the border between the inside and the outside. In documentation studies the concept of the paratext provides us with a terminology that allows us to place and name elements of a document belonging to its materiality.

Originality/value
In providing a case study based on archival material that has not been used before and is not available to a wider public, this paper shows the relevance of investigating films not as a repeatable unit with clear borders, but rather as an unbounded document.
Information in the knowledge acquisition process
Authors: Bosancic Boris 
Published: September 2016

PurposeThe purpose of this paper is to propose an appropriate symbolic representation, as well as its metaphorical interpretation, to illustrate the special role of information in the knowledge acquisition process.Design/methodology/approachBesides the literature review, this is a speculative study based on a symbolic and metaphorical point of view.FindingsThe proposed symbolic representation was derived from the conceptual designation of information “as a flow” and, accordingly, by the corresponding redrawing of the data-information-knowledge-wisdom (DIKW) pyramid. The knowledge acquisition process is symbolically represented by the growth of a “tree of knowledge” which is planted on a “data earth,” filled with “information sap” and lit by the rays of the “sun of the mind,” a new symbol of the concept of wisdom in the DIKW model. As indicated, a key concept of this metaphorical interpretation is the role of “information sap” which rises from the roots of the “tree of knowledge” to the top of the tree and it is recognized as an invisible link between “world of data” and “world of knowledge.” This concept is also proposed as a new symbolic representation of the DIKW model.Originality/valueOn the basis of specific symbolic-metaphorical representation, this paper provides a relatively new concept of information which may help bridge observed gaps in the understanding of information in various scientific fields, as well as in its understanding as an objective or subjective phenomenon.
Using the domain analytical approach in the study of information practices in biomedicine
Authors: Roos Annikki , Hedlund Turid 
Published: September 2016

Purpose
The purpose of this paper is to analyze the information practices of the researchers in biomedicine using the domain analytical approach.

Design/methodology/approach
The domain analytical research approach used in the study of the scientific domain of biomedicine leads to studies into the organization of sciences. By using Whitley’s dimensions of “mutual dependence” and “task uncertainty” in scientific work as a starting point the authors were able to reanalyze previously collected data. By opening up these concepts in the biomedical research work context, the authors analyzed the distinguishing features of the biomedical domain and the way these features affected researchers’ information practices.

Findings
Several indicators representing “task uncertainty” and “mutual dependence” in the scientific domain of biomedicine were identified. This study supports the view that in biomedicine the task uncertainty is low and researchers are mutually highly dependent on each other. Hard competition seems to be one feature, which is behind the explosion of the data and publications in this domain. This fact, on its part is directly related to the ways information is searched, followed, used and produced. The need for new easy to use services or tools for searching and following information in so called “hot” topics came apparent.

Originality/value
The study highlights new information about information practices in the biomedical domain. Whitley’s theory enabled a thorough analysis of the cultural and social nature of the biomedical domain and it proved to be useful in the examination of researchers’ information practices.
Hybrid cloud entropy systems based on Wiener process
Authors: Ibrahim Rabha Waell , Ghani Abdullah 
Published: September 2016

Purpose
The paper outlines a self-contained scheme for multiple networking agents at a location. It proposes a mathematical model for intelligent cloud entropy management systems. The purpose of this paper is to minimize the cost of system functionality by proposing the substantial use of a cloud-based system.

Design/methodology/approach
The paper proposes a hybrid cloud system, based on a fractional calculus of hybrid integral systems. Its discrete dynamics are suggested by using the fractional entropy type known as Tsallis entropy. This approach is based on the Wiener process (i.e. diffusion processes). This involves the net movement of information or data from a state of high meditation to a state of low observation. This property is a basic characteristic of hybrid cloud computing systems.

Findings
The paper offers a number of solutions to minimize the costs of cloud systems. The method is a proficient technique for presenting various types of fractional differential solutions.

Research limitations/implications
Researchers are encouraged to test and modify the proposed method.

Practical implications
The paper includes suggestions for the expansion of a powerful method for managing and integrating cloud systems stably.

Originality/value
This paper addresses an acknowledged need to study how the cost function of cloud systems can be achieved.

Authors: Yin Yong , Zhou Jian , Zhang Chaoyong , Chen Dejun 
Published: September 2016

Purpose
The purpose of this paper is to discuss an adaptive SLA mechanism for service sharing in virtual environment, which can organize and govern QoS items in terms of service execution time, reliability, and availability, and provides a common understanding about services, responsibilities, priorities, guarantees and warranties-related virtual cooperative issues.

Design/methodology/approach
The management framework for SLA is introduced, based on which the whole process including SLA contract, adaptive SLA negotiation strategy, SLA deployment and SLA assessment are discussed, and the prototype is implemented in the cloud manufacturing platform.

Findings
A proposed SLA framework for service sharing in virtual environments is given; electronic contracts are designed in the framework for encapsulating measurable aspects of service level agreements so as to provide common understanding about the service; and an improved SLA negotiation strategy with three phases is presented for the dynamicity of the virtual services.

Originality/value
The paper presents a very useful adaptive SLA mechanism for service sharing in virtual environments that can be utilized in concurrent or future advanced manufacturing modes.

Authors: Li Qiuxiang 
Published: September 2016

Purpose
The purpose of this paper is to explore the dynamics and stability of switched supply system considering the influence of the retailer competition and deteriorating items.

Design/methodology/approach
A discrete dynamic switched model is developed to analyze the evolution process of the switched supply chain. The existence and the local stability of the switched supply chain are analyzed using an analytical method and a parameter plot basin.

Findings
The author finds the switched supply chain will exhibit stable, periodic, and divergent behaviors with different parameters due to the system’s switching mechanism and the switched supply chain presents complex dynamics when the stable and unstable subsystem coexist.

Originality/value
The originality and value of the research rests on this paper considering the influence of the retailers’ competition and deteriorating items on the supply chain dynamics under stock-dependent demand. The obtained results provide the decision maker with some guidelines on how to make stable designs for the switched supply chain design according to the parameter values.
Limited public resources allocation model based on social fairness using an extended VIKOR method
Authors: Jiang Wenqi 
Published: September 2016

Purpose
Different from manufacturing resources allocation problems, the prices and amounts of limited public service resources could not be changed with the consumers’ requirements and social fairness is the most important objective for improving allocation efficiency. To measure social fairness reasonably, the purpose of this paper is fourfold: first, divide social fairness into longitudinal comparative fairness and crosswise comparative fairness, therefore providing their calculation formula and describing the comprehensive fair degree by using the interval numbers. Second, the comparison regulations of interval numbers are given and the corresponding features are also described. Third, an extension of VIKOR method is put forward for evaluating social fairness of different allocation alternatives with interval numbers. Finally, a numerical example illustrates the proposed method and clarifies the main results developed in the paper.

Design/methodology/approach
In this paper, the author depicts the social fair degree as an interval number, and thus proposes the comparison method between any two interval numbers. Based on the basis procedure of the VIKOR method, the paper proposes an extension of the fuzzy VIKOR method with the interval numbers to rank and select the compromise allocation alternatives. Finally, a numerical example illustrates the practicability of the proposed method.

Findings
The comparison of interval numbers is very important when the author evaluates the decision alternatives. Through analyzing the present comparison methods, the paper proposes the simple method of comparing the interval numbers, which can obtain the same results with the above two methods. The fuzzy VIKOR method, a popular multi-criteria decision-making method, focusses on ranking and selecting from a set of alternatives in a fuzzy environment. For the fuzzy value, the paper also proposes the extension of the VIKOR method to perform an evaluation and get the compromise alternatives.

Originality/value
According to the huge customers’ requirement, how to improve their social fair degree has become the focus in public service resources allocation, where the social fair degree may be a comprehensive concept which includes the fair degree compared with all the other allocation alternatives and the fair degree compared with the other small group under the same allocation alternative. In the paper, the author defines the above two types of fair degree and then depicts the comprehensive fair degree as their integration, which will be interval numbers.
