Pipelined data‐flow delegated orchestration for data‐intensive eScience workflows
Authors: Subramanian Sattanathan , Sztromwasser Paweł , Puntervoll Pål , Petersen Kjell 
Published: August 2013

PurposeeScience workflows use orchestration for integrating and coordinating distributed and heterogeneous scientific resources, which are increasingly exposed as web services. The rate of growth of scientific data makes eScience workflows data‐intensive, challenging existing workflow solutions. Efficient methods of handling large data in scientific workflows based on web services are needed. The purpse of this paper is to address this issue.Design/methodology/approachIn a previous paper the authors proposed Data‐Flow Delegation (DFD) as a means to optimize orchestrated workflow performance, focusing on SOAP web services. To improve the performance further, they propose pipelined data‐flow delegation (PDFD) for web service‐based eScience workflows in this paper, by leveraging from the domain of parallel programming. Briefly, PDFD allows partitioning of large datasets into independent subsets that can be communicated in a pipelined manner.FindingsThe results show that the PDFD improves the execution time of the workflow considerably and is capable of handling much larger data than the non‐pipelined approach.Practical implicationsExecution of a web service‐based workflow hampered by the size of data can be facilitated or improved by using services supporting Pipelined Data‐Flow Delegation.Originality/valueContributions of this work include the proposed concept of combining pipelining and Data‐Flow Delegation, an XML Schema supporting the PDFD communication between services, and the practical evaluation of the PDFD approach.
Various approaches to text representation for named entity disambiguation
Authors: Lašek Ivo , Vojtáš Peter 
Published: August 2013

PurposeThe purpose of this paper is to focus on the problem of named entity disambiguation. The paper disambiguates named entities on a very detailed level. To each entity is assigned a concrete identifier of a corresponding Wikipedia article describing the entity.Design/methodology/approachFor such a fine‐grained disambiguation a correct representation of the context is crucial. The authors compare various context representations: bag of words representation, linguistic representation and structured co‐occurrence representation. Models for each representation are described and evaluated. They also investigate the possibilities of multilingual named entity disambiguation.FindingsBased on this evaluation, the structured co‐occurrence representation provides the best disambiguation results. It showed up that this method could be successfully applied also on other languages, not only on English.Research limitations/implicationsDespite its good results the structured co‐occurrence context representation has several limitations. It trades precision for recall, which might not be desirable in some use cases. Also it is not able to disambiguate two different types of entities, which are mentioned under the same name in the same text. These limitations can be overcome by combination with other described methods.Practical implicationsThe authors provide a ready‐made web service, which can be directly plugged in existing applications using a REST interface.Originality/valueThe paper proposes a new approach to named entity disambiguation exploiting various context representation models (bag of words, linguistic and structural representation). The authors constructed a comprehensive dataset based on all English Wikipedia articles for named entity disambiguation. They evaluated and compared the individual context representation models on this dataset. They evaluate the support of multiple languages.
Sharia governance in Islamic banks: effectiveness and supervision model
Authors: Hamza Hichem 
Published: August 2013

PurposeThe Sharia governance is topic that has generated much interest in the literature of Islamic banking industry. The Sharia supervision plays an essential role in the governance of Islamic banks. The Sharia Board (SB) which is peculiar to Islamic banks is considered as the principal component of the Sharia governance framework. The purpose of this paper is to examines the link between Sharia compliance, the form of Sharia supervision and the effectiveness of Sharia governance.Design/methodology/approachThis paper compares two model of Sharia governance framework, the first is the decentralized model in the Gulf Cooperation Council (GCC) and the second is the centralized model in Malaysia.FindingsThe independence of the SB in their mission of supervision and the consistency of Sharia ruling are the principal components of an efficient Sharia governance structure. Centralized Sharia governance system, basically in Malaysia, seems to be beneficial to the industry in term of effectiveness and credibility of the Islamic banks.Research limitations/implicationsThe research focuses exclusively on the qualitative analysis about the SB and Sharia governance in Islamic countries.Practical implicationsThe model of centralization is able to strengthen the position and the independence of SB and can better examine the subjects of divergences between the whole of the SB in order to promote, in the long term, the consistency of Fatwas and interpretations between banks and regions.Originality/valueTo the best of our knowledge few studies have examined this subject in a comparative discussion between MENA and Southeast Asia region. This paper contributes to the literature on Sharia governance by considering the difference between these two regions in term of supervision model of Sharia rules and principles and its application in Islamic banking.

Authors: Anyango Tocho Jecton , Mwololo Waema Timothy 
Published: August 2013

Purpose
– The purpose of this paper is to provide an overview of e-waste management practices in Kenya and selected countries. It develops an ideal regulatory framework for e-waste management in Kenya.

Design/methodology/approach
– The methodology adopted for this paper includes collecting data using interviews, direct observation and literature review. Both qualitative and quantitative methods are used.

Findings
– Waste is an emerging stream of solid waste in Kenya. It has become a major concern due to the high volumes generated, its hazardous fractions and the lack of policies applicable to its disposal. Gaps are identified in the areas of awareness levels, e-waste management technology, financing, collection, disposal, monitoring, and stakeholder collaboration.

Research limitations/implications
– The study area is limited to Nairobi and its environs. With regard to product, the paper focuses on ICT equipment.

Practical implications
– The proposed framework has direct practical policy implications to manufacturers who ought to reduce e-waste from production, consumers who should adopt safe disposal practices, recyclers/informal actors who ought to use environmentally friendly methods and government agencies that enforce e-waste policies.

Social implications
– Adoption of the proposed framework has positive socio-economic impacts on job creation, reduced crime and sound environmental management.

Originality/value
– This paper adds to the body of knowledge on the e-waste problem from the perspective of developed as well as developing countries. It points out best practices for socio-economic development and fronts arguments for sustainable environmental management.
Organizational members’ use of social networking sites and job performance
Authors: Moqbel Murad , Nevo Saggi , Kock Ned 
Published: August 2013

PurposeThere is considerable debate among academics and business practitioners on the value of the use of social networking by organizational members. Some, fearing presenteeism (i.e. being at the workplace but working below peak capacity), claim that the use of social networking sites by organizational members is a waste of time, while others believe it leads to improvements in job performance, partly due to employees’ successful efforts to balance work‐life realms. This paper aims to inform this debate by examining the use of social networking sites by organizational members and its effect on job satisfaction, organizational commitment, and job performance.Design/methodology/approachThe exploratory study is based on a survey of 193 employees, focusing on the following constructs: social networking site use intensity, perceived job satisfaction, perceived organizational commitment, and job performance. The authors’ proposed model was evaluated using variance‐based structural equation modeling (SEM), a latent variable‐based multivariate technique enabling concurrent estimation of structural and measurement models under nonparametric assumptions. This study used WarpPLS 2.0 to assess both the measurement and the structural model.FindingsThe results show that social networking site use intensity has a significant positive effect on job performance through the mediation of job satisfaction, and that this mediating effect is itself mediated – in a nested way – via organizational commitment. The findings suggest that social networking site use, rather than causing presenteeism, may be a new way through which employees balance their work‐life realms, in turn benefitting their organizations.Originality/value – To the best of the authors’ knowledge, this is the first study to analyze, in an integrated way, the relationship between those theoretical constructs.
Don't give up the community: a viewpoint of trust development in online collaboration
Authors: Cheng Xusen , Nolan Terry , Macaulay Linda 
Published: August 2013

PurposeThis paper aims to examine the development of trust during online collaboration. The purpose of the inquiry is to improve the understanding of individual trust development in longitudinal online collaboration teams.Design/methodology/approachThe paper reveals the conclusion of a longitudinal online collaboration case study of two student cohorts over a two‐year period, where each cohort is in their first year, based on a previous trust research model. However, the study is conducted in a new context through the implementation of online collaboration tools. Data is collected using longitudinal surveys and in‐depth interviews.FindingsThe paper demonstrates that trust development in different online collaboration groups does not follow a particular pattern in this case study. This development is characterised by fluctuation and complexity. Trust development does not attain the ideal state discussed in previous research and trust development is different within each team. The paper provides insight into the complexities of trust development in an online collaboration environment and information system understanding.Research limitations/implicationsThe paper demonstrates the findings regarding development features are context‐specific and have not been subjected to testing for replication within other settings. The authors intend this for future research.Practical implicationsThe observations will help team leaders to understand changes in trust. It will also aid system developers and designers to consider trust development features in future system design for online collaboration environment and tools.Originality/valueThe paper builds upon a previous trust development model but applies it to the context of online collaboration using student groups to analyse the findings over time.
India's rural growth engine: the need to address rural diversity
Authors: Mookerjee Amit 
Published: August 2013

PurposeThe article aims to examine the rural‐urban divide used as a premise for idiomatic understanding of Indian rural consumers, and review current practices. This may be self limiting, and may trap marketers in an idiom that is not in touch with current realities in the rapidly evolving rural market. The paper highlights the rapid changes, emerging segments, the factors affecting change, and the need to revisit the rural idiom, with a more nuanced, stratified, granular look at the differences among rural consumer segments.Design/methodology/approachIt looks at existing literature and recent consumer survey reports, and notes the existing practitioner mindset, and current practices reported in literature industry forums and popular press.FindingsRecent surveys help posit the rise of the rural middle class, highlighting four sets of factors causing changes in the rural households' consumption patterns. It concludes that the most critical need is to understand values, needs, aspirations, social norms and realities, nature and pace of change to develop effective competitive strategies to address rural consumers, especially its middle class.Research limitations/implicationsIt is limited in its opinions due to the dependence on reports of prior surveys and existing literature.Practical implicationsIt identifies areas for future research to capture this change, and proposes the variables that must be kept in mind for generating adequate consumer insights. This is proposed through an initial re‐stratification and psychographic mapping of consumers for better rural marketing initiatives.Social implicationsMarketers have embarked on methods twining social uplift through economic empowerment, with programs building on distribution reach and efficiency helping them expand their own business. Better insights into rural diversity should help expand the programs and create more impact.Originality/valueIt has brought together diverse perspectives from practice and literature, and focussed attention on specific drivers of change, and how they will create greater diversity going forward. This will help focus on new segments, and proposes a newer paradigm for researching rural consumers.
Consumer attitude towards brand extension
Authors: Srivastava Kavita , Sharma Narendra K. 
Published: August 2013

PurposeThe present study aims to investigate the impact of perceived quality, brand extension incongruity, involvement and perceived risk on consumer attitude towards brand extension across three product types, namely, FMCG, durable goods and service (FDS) sectors. More importantly, the study seeks to explore the importance of involvement profile comprising relevance, pleasure, sign‐value, risk importance and risk probability and perceived risk facets (financial, psychological and performance) in acceptance of brand extension across FDS.Design/methodology/approachThree questionnaire‐based surveys were conducted to collect the data for FMCG, durable and service brand extensions. Regression analyses and Chow test were computed to investigate differences in consumer evaluation across FDS.FindingsResults revealed significant different effects of variables across the three product types. The impact of perceived quality was greater in the case of services than FMCG and durables. On the other hand, perceived risk and involvement had stronger influence on evaluation of durables and service than FMCG brand extensions.Research limitations/implicationsThe present study gives a comprehensive view of how consumers evaluate the service and non‐service brand extensions.Originality/valueThe major contributions of this study are: generalization of the findings related to brand extension incongruity in the service area; examination of the multidimensional role of involvement in terms of relevance, pleasure, sign value, risk importance and risk probability in brand extension context across FMCG, durables and service product types; and exploration of the role of risk facets, namely, financial, performance and psychological in determining consumers' attitude towards brand extension.
Founding‐family firms and the creation of value: Swedish evidence
Authors: Hamberg Mattias , Andre Fagerland Egil , Kvamme Nilsen Kristoffer 
Published: August 2013

PurposeThe purpose of this paper is to investigate the extent to which founding‐family firms create value. In particular, the paper investigates how agency costs and monitoring capabilities influence the value creation process.Design/methodology/approachThe empirical analysis relies on unique hand‐collected ownership data that has been collected for all Swedish publicly listed firms in the years 2001 to 2010 (2,128 observations). The research design employs level regression specifications and they are tested using pooled cross‐sectional regressions with controls for year and industry fixed effects.FindingsThe paper confirms previous studies that firms with founding family ownership have a higher value (Tobin's Q) and higher performance (RNOA). In contrast to prior studies, the paper finds that firm value and performance is significantly higher when ownership is concentrated the most. The paper also shows that firm value and performance is significantly lower for long‐term non‐founding‐family ownership.Originality/valueThis is one of the largest single‐country analyses of founding family owner effects on value and performance in publicly listed firms. The paper confirms known associations between ownership and performance in a unique institutional setting. The paper extends previous research findings by identifying differences in value and performance between founding family owners and long‐term non‐founding‐family owners.
Do “complex needs” need “complex needs services”? – part one
Authors: Johnson Robin 
Published: August 2013

PurposeThis paper – the first of two – aims to trace the origins of, and suggest the underlying intentions behind, the recent appearance of the new term “complex needs”, amongst commissioners, service providers and some service user groups.Design/methodology/approachThe paper takes a narrative approach, describing the early appearance of the term “complex needs” in services for those excluded from and/or stigmatised in mental health services. This is then contextualised with UK Government policy papers.FindingsContemporary usage of the term “complex needs” may at times be inconsistent and confusing; but it reflects government concerns that service provision has become too narrow in focus, and less needs‐led. The concept embodies an implicit critique of overly narrow practice, and holds the prospect of more systemic change.Originality/value“Complex needs” is relatively new, as a quasi‐technical term; as is any analysis locating its usage in the context of current overly narrow service definitions.
Social inclusion and personality disorder
Authors: Castillo Heather 
Published: August 2013

PurposeThis study aims to investigate the process of recovery for people diagnosed with personality disorder. This is related to the application of the new meaning of recovery from mental illness as explored by members of The Haven which, as the service setting for the study, addresses the problems of a client group that suffers significant social exclusion and aims to examine efforts which attempt to reverse this social exclusion.Design/methodology/approachA participatory action research approach was chosen for this study and The Haven Research Group, comprised of the author and Haven clients, formulated proposed research questions and conducted focus groups and individual client interviews with 66 participants, over a period of three years. The group has been concerned with the effectiveness of The Haven as a recovery tool from the perspective of service users and carers.FindingsAn examination of emerging themes, and the interplay between themes, gives insight into what participants considered to be the key steps to recovery for someone with a personality disorder diagnosis. From this thematic analysis, a map is proposed of the journey of recovery for people with the diagnosis.Practical implicationsAs an alternative to the historically sequential path of rehabilitation and proposed recovery, this study offers a new, socially inclusive way of working with people who have a personality disorder diagnosis where they may choose to retain a haven while continuing to develop and progress on their chosen path in the wider world.Social implicationsThe Haven has emerged as a unique model where therapeutic community principles have been combined with a crisis unit which shows that it is possible to work effectively with a relatively large number of people with personality disorder, well in excess of 100 at one time, many of whom had not made progress in other service settings, resulting in significant financial savings to the health, social care and criminal justice system.Originality/valueThis study offers contributions to knowledge in terms of the service design and proposes a new model of recovery in personality disorder. This is defined as a journey of small steps highlighting recovery as a process rather than a goal, leading to the emergence of the new concept of transitional recovery.
A motivational model of blog usage
Authors: Liao Chechen , To Pui‐Lai , Liu Chuang‐Chun 
Published: August 2013

PurposeThere has been an explosive growth of blog usage recently. However, little research has explored the forces motivating people to engage in blog activities. The purpose of this paper is to suggest that the driving forces to engage in blog participation not only includes utilitarian motivation (i.e. perceived usefulness) and hedonic motivation (i.e. perceived playfulness) but also habitual behaviour and social identity (blog identification). The quality of the blog is included as an antecedent to perceived usefulness and perceived playfulness.Design/methodology/approachIn total, 225 valid questionnaires were collected from blog users. Structural equation modelling was used to test the research hypothesis.FindingsThe results show that blog users' intentions to participate in blogs are determined by all four key drivers: habit, perceived playfulness, blog identification, and perceived usefulness. Blog quality has an effect on perceived usefulness and perceived playfulness.Research limitations/implicationsPrevious studies emphasise the importance of perceived usefulness as the key determinant for user acceptance of technology. However, in the blog context this study finds habit, perceived playfulness, and blog identification have more significant effects on users' intention than perceived usefulness.Practical implicationsBlog hosts should encourage habitual blog usage (habit), pay more attention to the hedonic nature of the blog (perceived playfulness) and establish a stronger sense of blog identification among participants, in order to retain active users.Originality/valueThis study articulates and empirically validates a motivational research model of blog usage, helping researchers to better understand such behaviour.
