Authors: Valles S. M , Chen Y , Firth A. E , Guérin D. M. A , Hashimoto Y , Herrero S , de Miranda J. R , Ryabov E ,   ICTV Report Consortium
Published: April 2017

Dicistroviridae is a family of small non-enveloped viruses with monopartite, linear, positive-sense RNA genomes of approximately 8–10 kb. Viruses of all classified species infect arthropod hosts, with some having devastating economic consequences, such as acute bee paralysis virus in domesticated honeybees and taura syndrome virus in shrimp farming. Conversely, the host specificity and other desirable traits exhibited by several members of this group make them potential natural enemies for intentional use against arthropod pests, such as triatoma virus against triatomine bugs that vector Chagas disease. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Dicistroviridae which is available at www.ictv.global/report/dicistroviridae.
ROLE of inter-related population-level host traits in determining pathogen richness and zoonotic risk
Authors: Lucas Tim C.D. , Wilkinson-Herbots Hilde M. , Jones Kate E.
Published: April 2017

Zoonotic diseases are an increasingly important source of human infectious diseases, and host pathogen richness of reservoir host species is a critical driver of spill-over risk. Population-level traits of hosts such as population size, host density and geographic range size have all been shown to be important determinants of host pathogen richness. However, empirically identifying the independent influences of these traits has proven difficult as many of these traits directly depend on each other. Here we develop a mechanistic, metapopulation, susceptible-infected-recovered model to identify the independent influences of these population-level traits on the ability of a newly evolved pathogen to invade and persist in host populations in the presence of an endemic pathogen. We use bats as a case study as they are highly social and an important source of zoonotic disease. We show that larger populations and group sizes had a greater influence on the chances of pathogen invasion and persistence than increased host density or the number of groups. As anthropogenic change affects these traits to different extents, this increased understanding of how traits independently determine pathogen richness will aid in predicting future zoonotic spill-over risk.

Published: April 2017

In order to better understand human preimplantation development we applied massively parallel RNA sequencing on 337 single cells from oocytes up to 8-cell embryo blastomeres. Surprisingly, already before zygote pronuclear fusion we observed drastic changes in the transcriptome compared to the unfertilized egg: 1,804 gene transcripts and 32 repeat elements become more abundant, among these the double-homeobox geneDUX4. Several genes previously identified asDUX4targets, such asCCNA1, KHDC1LandZSCAN4, as well as several members of theRFPLs, TRIMSandPRAMEFs1were accumulated in 4-cell stage blastomeres, suggestingDUX4as an early regulator. In the 8-cell stage, we observed two distinct cell types – a transcript-poor cell type, and a transcript-rich cell type with many Alu repeats and accumulated markers for pluripotency and stemness, telomere elongation and growth. In summary, this unprecedented detailed view of the first three days of human embryonic development reveals more complex changes in the transcriptome than what was previously known.
Spermatogonial Stem Cell Transplantation to the Testis
Authors: Goodyear Shaun , Brinster Ralph
Published: April 2017

Spermatogonial stem cells (SSCs) are located in the basal region of the seminiferous tubules and provide a self-renewing reservoir from which progenitor spermatogonia arise and transiently amplify in number before transition to a differentiating state. SSC transplantation involves grafting mouse testicular cells into the seminiferous tubules of an aspermic recipient testis that is generated either by chemical (e.g., busulfan) treatment or genetic mutations.
Preparation of a 3-kb Mate-Pair Library for Illumina Sequencing
Authors: Mardis Elaine , McCombie W. Richard
Published: April 2017

The “mate-pair” approach for dual end sequencing uses long library fragments (1000–10,000 bp) that are circularized by ligation to the ends of a single, common DNA adaptor of known sequence. Once the ends are mated to the adaptor, a final library of fragments that retain the adaptor and only the ends of the original, circularized piece of DNA can be obtained. This protocol describes how to prepare a 3-kb mate-paired-end library. The resulting amplified DNA is suitable for sequencing on the Illumina sequencer.
Fresnel zone plate with apodized aperture for hard X-ray Gaussian beam optics
Authors: Takeuchi Akihisa , Uesugi Kentaro , Suzuki Yoshio , Itabashi Seiichi , Oda Masatoshi
Published: April 2017

Fresnel zone plates with apodized apertures [apodization FZPs (A-FZPs)] have been developed to realise Gaussian beam optics in the hard X-ray region. The designed zone depth of A-FZPs gradually decreases from the center to peripheral regions. Such a zone structure forms a Gaussian-like smooth-shouldered aperture function which optically behaves as an apodization filter and produces a Gaussian-like focusing spot profile. Optical properties of two types of A-FZP, i.e. a circular type and a one-dimensional type, have been evaluated by using a microbeam knife-edge scan test, and have been carefully compared with those of normal FZP optics. Advantages of using A-FZPs are introduced.
Performance measurement system innovations in hospitals as translation processes
Authors: Leotta Antonio , Ruggeri Daniela
Published: April 2017

Purpose

The purpose of this paper is to highlight how the variety of the actors involved in a performance measurement system (PMS) innovation are spread out in time and space. Healthcare contests are examined, where such an innovation is influenced by present and past systems and practices (spread out in time), and by managerial and health-professional actors (spread out in space).

Design/methodology/approach

Drawing on Callon’s actor network theory, the authors describe PMS innovations as processes of translation, and distinguish between incremental and radical innovations. The theoretical arguments are used to explain the evidence drawn from a longitudinal case study carried out in an Italian public teaching hospital, referring to the period from 1998 up to 2003.

Findings

The conceptual framework shows how the translation moments lead to a recognition of the different actants involved in a PMS innovation, how their interests are interrelated and mobilized. Moreover, it shows how the interaction among the actants involved in the process is related to the type of PMS innovation, i.e. radical vs incremental. The case evidence offers detailed insights into the phenomenon, testing the explanatory power of the framework, and highlights how the failure of one of the translation moments can compromise the success of a PMS innovation.

Originality/value

This study differs from the extant accounting literature on PMS innovations as it highlights how the introduction of a new PMS can be affected by some elements of the previous systems “package,” which are relevant for the mobilization of the actants through the new project.
Reinventing organizational control
Authors: Brivot Marion , Gendron Yves , Guénin Henri
Published: April 2017

Purpose

The purpose of this paper is to provide insight into how a constellation of actors seek to define, shape, and reinvent the notion of organizational control at the confluence of social media (SM) and corporate reputational risk.

Design/methodology/approach

Following the approach suggested by Janesick (1998) and Denzin and Lincoln (1998), the authors undertook an in-depth qualitative analysis of a large number of data sources including interviews, best-selling books by renowned SM specialists, relevant press articles drawn from a Factiva search, and documents published by the Big Four firms and professional accounting institutes in Canada on how organizations should use SM to protect their reputational capital.

Findings

Four competing SM reputational risk control perspectives inductively emerged from the analysis: the Beyond Control frame, the Subveillance frame, the De-territorialization frame, and the Re-territorialization frame, with large accounting firms and professional accounting institutes especially promoting the latter.

Originality/value

The control literature has been criticized by many scholars as being in urgent need of updating. By inductively theorizing four original control frames in the SM arena, the research aims to move management control research in new directions.
Governing social media: the emergence of hybridised boundary objects
Authors: Arnaboldi Michela , Azzone Giovanni , Sidorova Yulia
Published: April 2017

Purpose

The purpose of this paper is to explore the processes whereby organisational actors can seize the opportunities opened up through social media, and the way in which the relative information is managed. This allows these actors to move their occupational boundaries, exploiting the information for performance measurement purposes. The investigation was carried out within an organisational setting, where most occupational dynamics take place. The focus was on the role of artefacts within these occupational dynamics and the analysis drew upon the notion of boundary objects.

Design/methodology/approach

The research was based on case studies involving two organisations that make use of social media within and across several departments. The authors conducted semi-structured interviews with social media managers, department managers, analysts and financial controllers and senior executives. The results of the qualitative analysis of the interviews were completed with secondary sources of information, company reports, communications, public policies, codes of conduct and social media platform analyses.

Findings

This paper has implications for accounting studies, showing how marketing and communications managers entering the field of performance management can take the lead in social media management by collecting information from social media, constructing indicators and gaining ground in several decision-making centres. The findings highlight the role of new artefacts and organisational roles, whose purpose is to build a digital community. This process involves crossing the boundaries between internal functions and the inside and outside environment, with a driving phenomenon becoming visible: hybridisation. Faced with this change, reluctant accountants with a traditional mindset are more likely to observe the process at a distance, focusing more on their routine operations based on conventional data.

Originality/value

This paper shows that information derived from social media is already a reality that has gained significance through the construction of boundary objects. The paper highlights a driving phenomenon that is emerging in the surge to occupy the organisational terrain for controlling social media: that of hybridisation. The concept of hybridisation is not new in management accounting studies, but in this study can be applied to carrying out a joint analysis on both the boundary objects and their organisational trajectory. In the context of social media accounting, hybridisation is of central importance if both actors and objects are to be effectively positioned at its boundary.
Design of an adaptive intelligent control scheme for switched reluctance wind generator
Authors: Hong Chih-Ming , Huang Cong-Hui , Cheng Fu-Sheng
Published: April 2017

Purpose

This paper aims to present the analysis, design and implementation of functional link-based recurrent fuzzy neural network (FLRFNN) for the control of variable-speed switched reluctance generator (SRG).

Design/methodology/approach

The node connecting weights of the FLRFNN are trained online by back-propagation (BP) algorithms. The proposed estimator requires less processing time than traditional methods and can be fully implemented using a low-cost digital signal processor (DSP) with MATLAB toolboxes. The DSP-based hybrid sensor presented in this paper can be applied to a wind energy-conversion system where the SRG is used as a variable-speed generator. The current transducer is used to monitor the energized current and proximity sensors for rotor salient.

Findings

The authors have found that optimal based on FLRFNN with Grey controller can resolve the regulation of the system with uncertainty model and unknown disturbances. This technique can maintain the system stability and reach the desired performance even with parameter uncertainties.

Originality/value

This design will improve the performance of SRG to operate more smoothly. This application is currently being studied because the SRG has well-known advantages such as robustness, low manufacturing cost and good size-to-power ratio. Performance of the proposed controller can offer better stability characteristics. Finally, the SRG has a very good efficiency in the whole operating range.
Optimum process mean, standard deviation and specification limits settings under the Burr distribution
Authors: Chen Chung-Ho , Chou Chao-Yu
Published: April 2017

Purpose

The quality level setting problem determines the optimal process mean, standard deviation and specification limits of product/process characteristic to minimize the expected total cost associated with products. Traditionally, it is assumed that the product/process characteristic is normally distributed. However, this may not be true. This paper aims to explore the quality level setting problem when the probability distribution of the process characteristic deviates from normality.

Design/methodology/approach

Burr developed a density function that can represent a wide range of normal and non-normal distributions. This can be applied to investigate the effect of non-normality on the studies of statistical quality control, for example, designs of control charts and sampling plans. The quality level setting problem is examined by introducing Burr’s density function as the underlying probability distribution of product/process characteristic such that the effect of non-normality to the determination of optimal process mean, standard deviation and specification limits of product/process characteristic can be studied. The expected total cost associated with products includes the quality loss of conforming products, the rework cost of non-conforming products and the scrap cost of non-conforming products.

Findings

Numerical results show that the expected total cost associated with products is significantly influenced by the parameter of Burr’s density function, the target value of product/process characteristic, quality loss coefficient, unit rework cost and unit scrap cost.

Research limitations/implications

The major assumption of the proposed model is that the lower specification limit must be positive for practical applications, which definitely affects the space of feasible solution for the different combinations of process mean and standard deviation.

Social implications

The proposed model can provide industry/business application for promoting the product/service quality assurance for the customer.

Originality/value

The authors adopt the Burr distribution to determine the optimum process mean, standard deviation and specification limits under non-normality. To the best of their knowledge, this is a new method for determining the optimum process and product policy, and it can be widely applied.
An artificial intelligent approach to the bicycle repositioning problems
Authors: You Peng-Sheng , Lee Pei-Ju , Hsieh Yi-Chih
Published: April 2017

Purpose

Many bike rental organizations permit customers to pick-up bikes from one bike station and return them at a different one. However, this service may result in bike imbalance, as bikes may accumulate in stations with low demand. To overcome the imbalance problem, this paper aims to develop a decision model to minimize the total costs of unmet demand and empty bike transport by determining bike fleet size, deployments and the vehicle routing schedule for bike transports.

Design/methodology/approach

This paper developed a constrained mixed-integer programming model to deal with this bike imbalance problem. The proposed model belongs to the non-deterministic polynomial-time (NP)-hard problem. This paper developed a two-phase heuristic approach to solve the model. In Phase 1, the approach determines fleet size, deployment level and the number of satisfied demands. In Phase 2, the approach determines the routing schedule for bike transfers.

Findings

Computational results show the following results that the proposed approach performs better than General Algebraic Modeling System (GAMS) in terms of solution quality, regardless of problem size. The objective values and the fleet size of rental bikes allocated increase as the number of rental stations increases. The cost of transportation is not directly proportional to the number of bike stations.

Originality/value

The authors provide an integrated model to simultaneously deal with the problems of fleet sizing, empty-resource repositioning and vehicle routing for bike transfer in multiple-station systems, and they also present an algorithm that can be applied to large-scale problems which cannot be solved by the well-known commercial software, GAMS/CPLEX.
Edges of sustainability through numbers, themes and discourse
Authors: Öztürk Mustafa
Published: April 2017

Purpose

The purpose of this paper is to identify critical gaps in the conceptualization and interpretation of sustainability by investigating the postgraduate research (theses and dissertations) conducted with a reference to sustainability in Turkish higher education institutions and synthesizing the underlying themes and trends pertaining to sustainability issues in the local discourse.

Design/methodology/approach

The study adopts a mixed-method design. The sample (n=343) consists of the theses and dissertations conducted over a ten-year period in Turkish universities. Data analysis procedures include a quantitative investigation through numbers to address the level of value attached to postgraduate research on sustainable development; a content analysis on the focus and scope of each study to determine prevalent sustainability themes and dimensions frequently addressed in the studies; and a collocation analysis conducted on the texts of the studies to depict linguistic and cultural connotations of sustainable development in the local discourse and key terms that frequently collocate with sustainable development in the Turkish context.

Findings

Neither a sufficient number of direct references to sustainability nor a substantial increase in the number of studies throughout the decade is depicted. Only one-third of Turkish universities steer postgraduate research on sustainability, which is not evenly distributed to various institutions across the country. Three-quarters of the studies are conducted within economy-related and engineering-related programs. The social dimension of sustainability is under-researched. The topics tend to ply between environmental and economic edges. Turkey, as a word, is collocated frequently with the concepts of external debt, current deficit, energy, policy, and EU. Linguistically, the concept of sustainable development is predominantly associated with economic growth in the majority of the studies. Sustainability is contextualized mostly with making cities inclusive, safe, resilient and sustainable and promoting inclusive and sustainable economic growth, employment, and decent work.

Originality/value

The value of the paper lies in the paucity of studies tracking the research initiatives taken on sustainability, assessing research trends in postgraduate programs of higher education institutions, and looking into a global concept from a local perspective in a developing country, Turkey.
Foreign owners and perceived job insecurity: evidence from linked employer-employee data
Authors: Dill Verena , Jirjahn Uwe
Published: April 2017

Purpose

The purpose of this paper is to examine the link between foreign ownership and perceived job insecurity. It takes into account that the link can depend on circumstances and type of firm.

Design/methodology/approach

The analysis is based on linked employer-employee data from Germany. The data enable us to account for both employee characteristics and firm characteristics. Most importantly, they allow a detailed analysis of moderating influences.

Findings

The estimates show that there tends to be a positive link between foreign owners and perceived job insecurity. The link is specifically strong for foreign-owned firms with high personnel turnover or poor employment growth. It is also stronger if the foreign-owned firm providing managerial profit sharing. However, the link tends to be negative for foreign-owned firms with product innovations.

Originality/value

Econometric examinations on the link between foreign ownership and perceived job insecurity are scarce. The study contributes to the literature by using linked employer-employee data and provides a detailed analysis of interaction effects.
Leader-member exchange differentiation and team member performance
Authors: Yuan Ling , Xiao Shiying , Li Jian , Chen Chen , Ning Lutao
Published: April 2017

Purpose

The purpose of this paper is to examine the relationship between leader-member exchange (LMX) differentiation and team members’ job performance. The conceptual model developed in this paper also investigates the moderating role of the perception of organisational politics (POP) in affecting the association between LMX differentiation and team members’ job performance.

Design/methodology/approach

The authors collected data using a survey from 32 Chinese firms. The questionnaire included scales measuring LMX, POP, job performance, and demographic variables. The final sample consisted of 122 teams with 561 employees. The hypothesised relationships among variables were assessed using hierarchical linear modelling.

Findings

The results show that the higher the LMX differentiation, the lower the level of team members’ contextual performance. The authors also found that POP has a significant effect in positively moderating the relationships between LMX differentiation and team members’ contextual and task performances.

Research limitations/implications

The conceptual model developed and verified in this paper provides essential insights for the research on LMX and job performance. Future studies are suggested to collect cross-national data to examine the conclusions of this study.

Originality/value

The association between LMX differentiation and team members’ job performance is moderated by the degree of POP.
Modelling project complexity
Authors: Rolstadås Asbjørn , Schiefloe Per Morten
Published: April 2017

Purpose

The purpose of this paper is to enhance the understanding of what project complexity is, what drivers and factors that influence complexity and how consequences for organizational performance can be assessed.

Design/methodology/approach

The research is explanatory and based on literature review, model development, interviews and case studies. The model is validated through a case study.

Findings

The findings are a model for identifying and analyzing complexity drivers and complexity factors. The model starts with generic complexity drivers such as ambiguity, uncertainty, unpredictability and pace. These drivers are in each project influenced by nature and by socio-political, economic and technological surroundings to result in complexity factors that are specific to the project analyzed. The model can be used to analyze project complexity and to define requirements for the organization of the project and guidelines for the execution.

Research limitations/implications

The research is limited to large projects with a technical delivery of some kind of facilities.

Practical implications

The model can be used to assess the required capability of the organization for successful project execution.

Originality/value

The contribution of the research is a new model for understanding project complexity. The distinction between project complexity drivers and factors is essential as well as the taxonomy for the factors building on and adding to already published research.
Ambiguity acceptance and translation skills in the project management literature
Authors: Gray Karmin , Ulbrich Frank
Published: April 2017

Purpose

The project management literature provides a fairly united picture of the importance of projects being successful. One success factor is represented by project managers themselves, whose personality, skills, knowledge, competencies, and traits affect project success. To better understand various project manager types, the purpose of this paper is to review the extant project management literature and propose a framework for categorising project managers based on the traits that they possess or lack.

Design/methodology/approach

The research commenced with identifying and collecting articles from the academic project management literature. The articles were then coded to identify different competencies and traits that a project manager needs to be successful. Based on this analysis, a framework with four main project manager types was developed.

Findings

The results indicate that ambiguity acceptance and translation skills are two important dimensions that project managers need to be successful. The four project manager types were arranged around two dimensions.

Research limitations/implications

The framework presented is based on previous research. Empirical testing of the proposed framework would be a promising direction for future research.

Practical implications

The framework assists reflective practitioners in identifying what kind of project manager they currently are, suggesting how they might transition into a different project manager type to increase their project management success rate.

Originality/value

This paper conceptualises project managers and how their personal traits relate to project success. It offers practical help to project managers in understanding their strengths and limitations, and how to become a different type of project manager.
Ethical behaviour in the design phase of AEC projects
Authors: Lohne Jardar , Svalestuen Fredrik , Knotten Vegard , Drevland Frode Olav , Lædre Ola
Published: April 2017

Purpose

The purpose of this paper is to report on studies on the ethics in the design phase in Norwegian construction projects. The ambition is to establish a descriptive picture of ethical challenges practitioners meet in the design phase in order to raise awareness among them.

Design/methodology/approach

In addition to a literature review and a document study of ethical frameworks within the industry, interviews with key participants were carried out according to a qualitative approach. The study was undertaken in order to address framework conditions for handling ethically challenging situations, challenges of an ethical nature practitioners commonly encounter in the design phase and finally the structural (systemic) reasons for such challenges.

Findings

This research finds indications of actors manoeuvring in the design phase for own benefit at the expense of other actors. The findings equally indicate that the design phase poses significant challenges in light of tender documents pricing and exploiting cost reimbursement contracts. In some of the projects examined, participants shifted loyalty after novation contracting and they actively tried to steer the decision processes in their own favour.

Originality/value

There does in fact seem to be perceptions of a room of manoeuvre between what is unlawful and what is ethically sound in this phase.
Social work intervention with adults who self-neglect in England: responding to the Care Act 2014
Authors: Anka Ann , Sorensen Pernille , Brandon Marian , Bailey Sue
Published: April 2017

Purpose

The purpose of this paper is to report on findings from an evaluative research study which looked at a timed intervention model of practice comprising of up to 24 weeks of intensive meetings with adult service users set up by one local authority in England, to prevent and delay the need for care and support. A particular focus of this paper is on adults who hoard.

Design/methodology/approach

The study employed a mixed-methods design, consisting of interviews with service users (n=13), social workers (n=3), social work managers (n=2) and stakeholders from external services and agencies (n=6). It included a costing analysis of staff time and an analysis of goals of service users and “satisfaction with life” self-report questionnaires (n=20), completed at pre- and post-intervention stages.

Findings

There was evidence that social workers used strengths, relationship-based and outcome-based focused approaches in their work. The techniques used by social workers to engage, achieve change and assess effectiveness with service users varied. These techniques included the use of photographs to enable the service user to map and assess their own progress over time, encouraging hoarders to declutter and reclaim their living space. The service users valued the time the social workers spent with them and the way that they were treated with sensitivity and respect.

Research limitations/implications

The study focused on one local authority in England; there was no comparison group. This, and the small sample size, means that statistical generalisations cannot be made and only limited conclusions can be drawn from the quantitative data.

Originality/value

The paper provides insights into the work undertaken by social workers with adults who hoard. It contributes to the body of knowledge on effective social work interventions with adults who hoard.
The impact of product architecture on global operations network design
Authors: Pashaei Sebastian , Olhager Jan
Published: April 2017

Purpose

The purpose of this paper is to explore how integral and modular product architectures influence the design properties of the global operations network.

Design/methodology/approach

The authors perform a multiple-case study of three global manufacturing companies, using interviews, seminars and structured questionnaires to identify ideal design properties.

Findings

The authors find that the choice of integral vs modular product architecture lead to significant differences in the preferred design properties of global operations networks concerning number of key technologies in-house, number of capable plants, focus at assembly plants, distance between assembly plant and market, and number of key supplier sites. Two of these were identified through this research, i.e. the number of capable plants and number of key supplier sites. The authors make a distinction between component and assembly plants, which adds detail to the understanding of the impact of product architecture on global operations. In addition, they develop five propositions that can be tested in further survey research.

Research limitations/implications

This study is restricted to three large manufacturing companies with global operations. However, the authors investigated both integral and modular products at these three companies and their associated global operations network. Still, further case or survey research involving a broader set of companies is warranted.

Practical implications

The key aspects for integral products are to have many key technologies in-house, concentration of production at a few capable plants, and economies-of-scale at assembly plants, while long distances between assembly plants and markets as well as few key supplier sites are acceptable. For modular products, the key aspects are many capable plants, economies-of-scope at assembly plants, short distance between assembly plants and markets, and many key supplier sites, while key technologies do not necessarily have to reside in-house – these can be accessed via key suppliers.

Originality/value

This paper is, to the authors’ knowledge, the first study on the explicit impact of product architecture on global operations networks, especially considering the internal manufacturing network.
Emergency materials transportation model in disasters based on dynamic programming and ant colony optimization
Authors: Liu Jia , Xie Kefan
Published: April 2017

Purpose

While scheduling and transporting emergency materials in disasters, the emergency materials and delivery vehicles are arriving at the distributing center constantly. Meanwhile, the information of the disaster reported to the government is updating continuously. Therefore, this paper aims to propose an approach to help the government make a transportation plan of vehicles in response to the disasters addressing the problem of material demand and vehicle amount continual alteration.

Design/methodology/approach

After elaborating the features and process of the emergency materials transportation, this paper proposes an emergency materials scheduling model in the case of material demand and vehicle amount continual alteration. To solve this model, the paper provides the vehicle transportation route allocation algorithm based on dynamic programming and the disaster area supply sequence self-learning algorithm based on ant colony optimization. Afterwards, the paper uses the model and the solution approach to computing the optimal transportation scheme of the food supply in Lushan earthquake in China.

Findings

The case study shows that the model and the solution approach proposed by this paper are valuable to make the emergency materials transportation scheme precise and efficient. The problem of material demand and vehicle amount changing continually during the process of the emergency materials transportation is solved promptly.

Originality/value

The model proposed by this paper improves the existing similar models in the following aspects: the model and the solution approach can not only solve the emergency materials transportation problem in the condition of varying demand and vehicle amount but also save much computing time; and the assumptions of this model are consistent with the actual situation of the emergency relief in disasters so that the model has a broad scope of application.
Measurement of knowledge diffusion efficiency for the weighted knowledge collaboration networks
Authors: Su Jiafu , Yang Yu , Zhang Na
Published: April 2017

Purpose

The purpose of this paper is to propose a valid and quantitative measurement method of knowledge diffusion efficiency for the knowledge collaboration networks (KCNs).

Design/methodology/approach

This paper builds a weighted KCN model with the node and edge weights. Based on the weighted KCN, the factors of knowledge diffusion efficiency are proposed and analyzed. Then, the knowledge transfer effect between two nodes is proposed and measured by comprehensively integrating the above factors. Furthermore, the main metric of efficiency of knowledge diffusion is proposed by modifying Latora and Marchiori’s model of efficiency of network.

Findings

A case is studied to illustrate the applicability of the proposed weighted network model and the knowledge diffusion efficiency measurement method. The results show the methods proposed in this paper can better measure and analyze the knowledge diffusion efficiency of KCNs than the traditional un-weighted methods and the subjective evaluation methods.

Originality/value

The real KCNs are always weighted networks. The weighted model of KCN can better reflect the real networks than the un-weighted model. Based on the weighted networks, the measurement methods proposed in this paper can more efficiently and accurately measure and evaluate the knowledge diffusion efficiency than the traditional methods. This study can help researchers to better understand knowledge diffusion theoretically, and provide managers with a decision support for knowledge management in practice.
Beyond preservation: investigating the roles of archivist
Authors: Vassilakaki Evgenia , Moniarou-Papaconstantinou Valentini
Published: April 2017

Purpose

This paper aims to identify through a systematic review the roles that archivists adopt in a changing archival landscape and to illustrate any similarities between the roles of archivist and librarians.

Design/methodology/approach

The systematic literature review approach was adopted for the purposes of this research. Specifically, peer-reviewed literature published in English between 2000 and 2015 was considered. The relevant papers were retrieved based on specific search terms run on related databases.

Findings

The analysis showed that the traditional roles of record-keeper and collection manager were still relevant, whereas new ones, namely, digital archivist, archivist as educator and dual archivist/librarian, started to prevail. The technological developments as well as the social and educational changes seemed to have affected the emergence of these new roles, whereas the need for collaboration and communication among archivists, librarians and researchers was evident in many roles, namely, archivist as educator, dual archivist/librarian and archivist as researcher.

Originality/value

This literature review explored the different roles that archivists adopt within their work context and not the archivists’ skills, duties and responsibilities.
Open innovation in the food and beverage industry
Authors: Bayona-Saez Cristina , Cruz-Cázares Claudio , García-Marco Teresa , Sánchez García Mercedes
Published: April 2017

Purpose

The purpose of this paper is to extend the knowledge into the relationship between open innovation (OI) and firm’s innovative performance. Specifically, the authors aim to determine whether the benefits of OI practices are different for Food and Beverage (FnB) firms as compared to those of other sectors. The FnB industry is relevant in terms of employment GDP generation in the UE, characterised by high integration and low-tech intensity.

Design/methodology/approach

In order to achieve the goal and obtain robust results, the authors consider four OI dimensions and four innovation performance measures using panel data (2004-2011) from 10,771 FnB and non-FnB firms using Tobit and Logit models by random effects.

Findings

The authors test and confirm the presence of the classical inverted U-shape relationship between OI and firm innovative performance for FnB and non-FnB companies. However, the optimal number of external sources of knowledge used is lesser for FnB than the rest of the companies.

Originality/value

The paper compares the OI effects in a traditional and low-tech industry vs other industries considering four innovation outputs (product innovations, process innovations, incremental innovation and radical innovation).
The role of affective commitment in the relationship between social support and turnover intention
Authors: Fazio John , Gong Baiyun , Sims Randi , Yurova Yuliya
Published: April 2017

Purpose

The purpose of this paper is to argue that affective commitment plays a significant and complex role in the relationship between social support and turnover intention.

Design/methodology/approach

Surveys were returned by 217 hospital employees with an average tenure of 11.55 years (SD=10.20).

Findings

Findings suggest that perceived organizational support and perceived supervisor support (PSS) could directly impact turnover intention without the mediation of affective commitment. Thus, affective commitment only partially mediates the negative relation between perceived support and turnover intention. In addition, the results suggest that enhanced PSS reduced turnover intention more powerfully, when affective commitment increased. For a highly committed employee, support from the supervisor can be more influential than that of a less committed employee.

Originality/value

This is an initial investigation on the moderating role of affective commitment in the relationship between perceived social support and turnover intention. Further, the findings emphasize the independent impact of perceived social support above and beyond the effect mediated by affective commitment, thus adding evidence to the debate on the extend of the mediating effect of affective commitment.
Effects of management control systems and cognitive orientation on misreporting: an experiment
Authors: Sánchez-Expósito María J. , Naranjo-Gil David
Published: April 2017

Purpose

The purpose of this paper is to analyze the simultaneous effect of management control system (MCS) designs (belief vs boundary) and cognitive orientations (individualism vs collectivism) on performance misreporting by combining accounting and psychology literature.

Design/methodology/approach

This paper is based on a laboratory experiment with 67 postgraduate students.

Findings

Results show that an individualist cognitive orientation increased performance misreporting. The results also showed that a boundary design of MCS intensified the relationship between individualist orientation and performance misreporting.

Research limitations/implications

This paper shed some light about the role of non-pecuniary control system for reducing managerial performance misreporting. The findings support that the tendency of individuals to avoid misreporting depends not only on the MCS design but also on the match between it and individual’s cognitive orientations.

Practical implications

Managers in organizations should consider the predominant cognitive orientation of individuals when they design MCS. They should consider that control systems, which impose coercive constraints to individuals, may encourage feelings of psychological reactance and then increase performance misreporting.

Originality/value

This study is among the first to combine psychology and accounting literature to analyze how the design of MCS influences individuals’ motivation to misreport their performance. It provided evidence about the effect of non-monetary control systems on individual’s behavior in organizations.
The disappearing abnormal returns to a fundamental signal strategy
Authors: Dorey John , Kim Sangwan , Shin Yong-Chul
Published: April 2017

Purpose

The purpose of this paper is to examine whether abnormal returns to a fundamental signal (FS) strategy disappear after the publication of Abarbanell and Bushee (1998).

Design/methodology/approach

Using data on NYSE/AMEX firms from 1974 to 2012, this research estimates annual Fama and MacBeth (1973) cross-sectional regression of risk-adjusted buy-and-hold returns on the FSs after controlling for contemporaneous earnings changes and a proxy for market risk.

Findings

This paper finds that predictable hedge returns to the FSs substantially decrease and become statistically insignificant after the Abarbanell and Bushee’s publication date. This research also finds that the FSs have not lost their importance to equity valuation process; value relevance of the FSs has not diminished, and the FSs have retained their predictive ability over time. The evidence on changing information and trading environments appears to contribute to the disappearing abnormal returns to a FS strategy.

Originality/value

This paper adds to the growing body of literature on the persistence of pricing anomalies.
Bank lending and bank relationships in China: guanxi or commercial?
Authors: Yin Wei , Matthews Kent
Published: April 2017

Purpose

China as a main emerging and transition economy has since 2006 opened up its banking market to foreign competition. Thus far, the penetration of foreign banks has been only moderate with around 2 per cent market share of the total banking market, despite the widely held view that foreign banks operate at a higher level of efficiency and that Chinese state-owned banks (SOBs) operate at a lower level of efficiency. The purpose of this paper is to explore the relationship between bank ownership and the lending behaviour and relationship banking that stems from the Chinese tradition of “guanxi”.

Design/methodology/approach

Based on three bank types the authors construct a model of the choice of bank type and show how that model can be estimated using a multinomial logit. The authors assume that firms choose a bank type as a function of firm characteristics (Berger et al., 2008; Ongena and Sendeniz-Yüncü, 2011), deal terms (Machauer and Weber, 2000; Ziane, 2003), and industry classification (Uchida et al., 2008; Ongena and Sendeniz-Yüncü, 2011).

Findings

This paper finds the existence of a close banking relationship of a “guanxi” type between SOBs and state-owned enterprises (SOEs). This is shown up in the form of better deal terms for the SOE. In the case of foreign banks the authors find that a foreign bank-foreign owned enterprise relationship exists but this is based on risk quality and no advantages in deal terms, which suggest a more commercial-based relationship. The empirical findings are that transparent and high-quality firms are likely to engage with foreign banks, while state-owned firms are more likely to engage with SOBs.

Originality/value

In China, few studies have addressed the potentially important role of bank ownership on lending behaviour (e.g. Firth et al., 2008; Berger et al., 2009). The authors extend the analysis by distinguishing not only between foreign and domestic banks, but also between SOBs and other domestic banks. This research seeks to enhance the understanding of bank ownership, lending behaviour and relationship banking.
Influences of key stakeholders’ involvement in maintenance management
Authors: Au-Yong Cheong Peng , Ali Azlan-Shah , Ahmad Faizah , Chua Shirley Jin Lin
Published: April 2017

Purpose

Proper maintenance management ensures a long-term investment and provides a support function in business continuity to achieve organisational goal. However, inadequate involvement and participation of key stakeholders in maintenance management limit the continuous improvement of maintenance performance. Currently, there is a lack of studies about the influence of key stakeholders’ involvement in maintenance. Thus, the purpose of this paper is to deal with enhancement of maintenance management through the involvement of key stakeholders.

Design/methodology/approach

This research adopted a mixed method approach to determine the relationship between involvement of key stakeholders in maintenance management and maintenance effectiveness. The approach comprised of literature review, questionnaire survey and semi-structured interviews.

Findings

This research suggests a positive correlation between involvement of maintenance manager (MM), maintenance staff, organisation, user and maintenance service provider (SP) in improving the effectiveness of maintenance management. The logistic regression analysis indicated that the involvement of MM and SP are significant predictors of maintenance effectiveness. The research further identified that there was a lack of involvement of the user and SP in maintenance management.

Originality/value

The research demonstrated that all key stakeholders should value the important roles of their participation in maintenance management to ensure an optimum return on a long-term investment. To create the awareness for the involvement of key stakeholders in building maintenance, studies on the advantages of participating in building maintenance and the impacts of ignorant towards building maintenance can be beneficial to the industry.
