Authors: Hong‐jun Li , Wei Hu , Zheng‐guang Xie , Wei Wang 
Published: August 2013

PurposeThe paper aims to do some further research on grey relational analysis applied in wavelet transform, and proposed a grey relational threshold algorithm for image denoising. This study tries to suppress the noise while retaining the edges and important structures as much as possible.Design/methodology/approachThe paper analyzed the characters of noises and edges distribution in different subbands; then used the grey relational value to calculate the relationship of scale, direction and noise deviation. This paper used the grey relational value of scale, direction and noise deviation as influenced factors, and proposed a grey relational threshold algorithm.FindingsGrey relational analysis used in threshold setting has the superiority in image denoising. The simulation results have already certified both in visual effect and peak signal to noise ratio (PSNR).Originality/valueThis paper applied grey relation theory into image denoising, and proposed a grey relational threshold algorithm. It provides a novel method for image denoising.
Measuring child and adolescent health literacy: a systematic review of literature
Authors: Ormshaw Michael J. , Paakkari Leena T. , Kannas Lasse K. 
Published: August 2013

PurposeA systematic review of literature was conducted to compile, analyse and describe the methodology and measurement of childhood/adolescent health literacy.Design/methodology/approachSix online databases (ERIC, PubMed, CINAHL, Biomed Central, Web of Science and Sports Discuss) were systematically searched to identify English language, peer‐reviewed articles, published between 1980 and April 2011, which reported on the measurement of health literacy in a population under the age of 18. The search identified 16 articles to be included in the final review, from which, data were systematically extracted in order to answer four review questions concerning several aspects of the method and effectiveness of the completed studies.FindingsThe majority (n=13) of the studies described the use of newly developed measurement tools and enquiry methods. The majority (n=14) assessed health literacy via task performance as opposed to examining self‐reported health literacy. Thirteen health topics and nine distinct components of health literacy were identified as being scrutinised by the 16 articles. Examination of the intended measurement aims of each study, in comparison with the actual measurement methods revealed that six studies fully succeeded in examining what they intended to measure. It is concluded that even though research in this field is escalating, clear definitions and measurement methods of childhood health literacy must be developed in order to effectively expand the field further and comprehensively assess childhood health literacy.Originality/valueThis review is to our knowledge the first to collate and examine studies concentrating solely on the measurement of health literacy in a child and/or adolescent population.
Health‐related messages in food advertisements targeting children
Authors: Castonguay Jessica , McKinley Christopher , Kunkel Dale 
Published: August 2013

PurposeThe goal of this study was to assess the use of “health” messages in food advertising in the USA which target children. The aim was to determine if these messages indicate the promotion of a healthful product or are a marketing tactic to promote unhealthy items, potentially undermining nutrition education efforts.Design/methodology/approachA content analysis of food advertisements (n=534) in children's television shows (n=141) was performed to identify three types of health messages. The type of products promoted with such messages and the nutritional value of those products were assessed.FindingsOver half of food advertisements targeting children use “health” messages, with commercials for fast foods and sugared cereals most likely to include them. The majority of advertisements for nutritionally poor foods include a “health” message.Research limitations/implicationsThe findings from this research cannot be used to predict the impact health messages have on young viewers, but rather describe the content. Quantification of this content then provides the basis for tracking changes to marketing practices over time.Practical implicationsThis study raises concern that food advertisements targeting children may prime misleading perceptions of a food's actual nutritional value. Educators should be aware of the need to assist children in adequately interpreting “health” messages in advertising.Originality/valueLittle research to date has examined the “health” related messages presented in food advertisements targeting children. To our knowledge this is the first study to examine not only the presence of “health” messages but the actual nutritional quality of foods promoted to children with such messages.
Assessing the impact of ERP on supplier performance
Authors: Hwang Woosang , Min Hokey 
Published: August 2013

PurposeThrough an empirical study, this paper identifies a multitude of drivers that facilitate or hinder the implementation of enterprise resource planning (ERP) in business environments. Also, the purpose of this paper is to analyze its role in supply chain operations and assesses its impact on supplier capabilities and performances from supply chain perspectives.Design/methodology/approachBased on both a contingency theory and a resource‐based view (RBV) of the firm, the research develops a series of hypotheses regarding the use of ERP for strategic sourcing. A large‐scale survey of Korean manufacturers and their suppliers was conducted. A structural equation model was used for data analysis.FindingsThe firm's external environment (EE) has little influence on its decision to adopt and implement ERP. However, through the mediating role of an internal environment (IE), an EE still indirectly influences the ERP adoption and ERP implementation (ERPI) decision. Also, the paper found that ERP could enhance the ERP adopter's supplier capability (SCAP).Originality/valueThis study investigates the role of ERP in the supply chain and identifies important determinants influencing the ERP adoption and implementation decisions. Especially, this paper assesses the benefits of ERP from the ERP adopter's supply chain partner's standpoints.
Determining business models in bottom‐of‐the‐pyramid markets
Authors: Jun Sungbum , Lee Dongmyung , Park Jinwoo 
Published: August 2013

PurposeThis paper aims to develop a multi‐criteria approach for determining business models in bottom‐of‐the‐pyramid (BOP) markets.Design/methodology/approachAnalytic network process (ANP) was employed to construct a decision‐making model of quantitative and qualitative factors relevant to BOP markets. Alternatives can be evaluated, respectively, and further business implications can be delivered to decision makers through continuous improvement of the model.FindingsANP is a tool that can address the interdependencies among decision elements and alternatives in the BOP markets. Moreover, it can be employed in structural analysis of the network of relationships among the selection criteria.Practical implicationsDecision makers can make more informed decisions by using the proposed approach, which is targeted toward BOP customers. This approach also overcomes the flaws of previous approaches.Social implicationsThe successful selection of business models for BOP markets can change how multinational companies think about BOP consumers, allowing the poor to be perceived as value‐demanding customers. In addition, if multinational companies create new local business models, the quality of life of the poor could be improved.Originality/valueThe consideration of interdependencies among the criteria relevant to the selection of successful business models in BOP markets is a novel conceptual contribution.
Supervisory control service for supporting flexible processes
Authors: Alves Portela Santos Eduardo , Francisco Rosemary , Pesic Maja , van der Aalst Wil 
Published: August 2013

PurposeIncreasing flexibility and complexity of modern process‐aware information systems (PAIS) usually leads to less guidance for its users and consequently requires more experienced users. A flexible PAIS allows users to freely choose a specific execution sequence of activities. However, there are no guarantees that the chosen sequence conforms to established business rules. This context proposes a supervisory control service (SCS), which can be used to support end‐users of flexible PAIS during process execution by giving a list of disabled (or enabled) events (activities), i.e. at any point in time a list of possible next steps is given.Design/methodology/approachThe SCS has been implemented in process mining framework (ProM – www.processmining.org) and the experiment that has been performed shows its feasibility. The computational infrastructure already implemented in ProM allows communication with external applications and allows the SCS to be integrated with PAIS that records events. This paper demonstrated that the SCS in ProM can cooperate with PAIS system in order to support users.FindingsThe SCS proposed in this paper monitors and restricts execution sequences of activities such that business rules are always obeyed. The system offers support based on business rules but does not limit the user by imposing rigid control‐flow structures. Users can adopt this service as a guide to execute activities with a guarantee that business rules are followed and goals are met. The SCS also offers flexibility to users to choose execution sequences.Originality/valueThe paper argues that the proposed approach has many advantages on controlling/supporting flexible processes. Supervisory control theory allows an automatic control synthesis instead of the usual manual and heuristic procedures. Thus, new control actions may be rapidly and automatically designed when modifications, such as redefinition of business rules or activities arrangements, are necessary. The flexible processes can be made to behave optimally with respect to a variety of criteria, where optimal means in minimally restrictive way.
Fashion founded on a flaw
Authors: McSweeney Brendan 
Published: August 2013

PurposeTo comment on Brewer and Venaik's review of the misapplication of the national culture dimensions of Hofstede and GLOBE at the individual and other sub‐national levels. This paper supports and extends their critique.Design/methodology/approachThe implausibility of deterministic claims about the multi‐level power of national culture is described and discussed by drawing on a wide range of disciplines (including anthropology, geography, sociology, and historiography).FindingsDescriptions of the characteristics and origins of sub‐national level behaviour based on a priori depictions of national culture values are invalid and misleading.Practical implicationsThere are important implications for practitioners. The paper highlights the unsoundness of descriptions of the sub‐national (individuals, consumer segments, organizations, and so forth) which are derived from national‐level depictions of culture and the dangers of ignoring the independent causal influence of non‐national culture and non‐cultural factors.Originality/valueThe ecological fallacy in the national culture literature is located within a wider and long‐standing critique of that fallacy. The paper is the first to show that the fallacy in the national culture literature is often an extreme causal version. It not merely supposes cross‐level equivalence, as in the standard version, but more aggressively, it attributes deterministic power to national culture thus excluding other independent influences and agency.
Real estate market factors and foreign real estate investment
Authors: Gholipour Fereidouni Hassan , Ariffin Masron Tajul 
Published: August 2013

PurposeThe purpose of this paper is to examine the effects of real estate market factors on foreign real estate investment (FREI).Design/methodology/approachApplying panel data technique, this paper uses related observations from 31 countries (inclusive of developed countries and emerging market economies) between 2000 and 2008 to investigate the relationships between real estate market factors and FREI.FindingsControlling for market size, infrastructure and political stability, the results for all countries indicate that lower financing costs and higher levels of transparency in real estate market attract greater amounts of FREI. Moreover, the paper finds that foreign real estate investors favor countries with higher property prices. Interestingly, when the paper splits the sample in developed countries and emerging market economies the paper finds that there are some differences in results in terms of determinants of FREI.Originality/valueWhile FREI is a large component of service FDI, currently there are no analyses of FREI determinants across a broad set of countries over time. Therefore, the present study has filled this gap.
Credibility and the credit channel transmission of monetary policy theoretical model and econometric analysis for Brazil
Authors: Caldas Montes Gabriel , Cabral Machado Caroline 
Published: August 2013

PurposeThe purpose of this paper is to present a theoretical model and empirically verifies the transmission of monetary policy through the credit channel in Brazil. The study verifies if the monetary policy, the economic activity and the maturity of the inflation targeting regime affect the supply of credit.Design/methodology/approachThe paper offers a review of the literature concerning inflation targeting credibility and the transmission mechanism of monetary policy through the credit channel, it develops a theoretical model based on Bernanke and Blinder and Ferreira and it seeks empirical evidence for the Brazilian economy using ordinary least squares, generalized method of moments and vector autoregressive.FindingsThe estimates indicate that the supply of credit is stimulated when the economy heats up, when the monetary authority reduces the interest rate and when the credibility increases. The evidence also indicate that the supply of credit is affected by the variables of the model, economic activity and employment are affected by monetary policy and the supply of credit exerts influence on both employment and output gap.Research limitations/implicationsAn important implication of this study is that, in inflation targeting emerging economies, such as that of Brazil, following a committed monetary policy to price stability which increases the credibility of the regime of inflation targeting and promoting macroeconomic stability represents a good strategy for improving the volume of lending to the private sector, thus stimulating economic activity and employment. What the findings do indicate is that developing credibility is crucial for emerging economies that are trying to grow, but with inflation being kept under control.Originality/valueThe paper presents the following theoretical and empirical contributions: the model incorporates the effect that the credibility of the inflation targeting regime has on the supply of credit and, the econometric approach provides evidence that the monetary policy, the economic activity and the process of anchoring of inflation expectations affect the supply of credit in Brazil. Moreover, the paper finds evidence that the credit channel acts as a transmission mechanism of monetary policy to the economy.
Corporate financing activities, fundamentals to price ratios and the cross section of stock returns
Authors: Papanastasopoulos Georgios , Thomakos Dimitrios , Wang Tao 
Published: August 2013

PurposeThe purpose of the paper is to investigate the relation between the value/growth anomaly and the external financing anomaly by considering an expanded value/growth indicator: free cash flow yield (free cash flows scaled by price).Design/methodology/approachThe paper utilizes portfolio‐level tests and cross‐sectional regressions.FindingsIn line with the literature on contrarian portfolios, this paper finds that firms with low (high) free cash flow yield are experiencing low (high) returns. However, only when an investor buys (sells) stocks of firms with high (low) free cash flow yield that distribute (raise) capital, his zero‐cost portfolio is significant. These findings are robust, irrespective of the financing vehicle (equity or debt). Overall, their evidence suggests that distinctions between the value/growth anomaly and the external financing anomaly partially disappear, if one is willing to employ free cash flow yield as a proxy of the former anomaly.Originality/valueThe paper enhances one's understanding of the relation between asset pricing anomalies.
Integrated care in Herefordshire: a case study
Authors: Coupe Michael 
Published: August 2013

PurposeThe paper draws on the experience of the health and social care system in Herefordshire to answer what, when and how improvements in cost and quality can be realised through service integration.Design/methodology/approachThe three stages in the evolution of integrated health and social care services within the county and the establishment of Wye Valley NHS Trust are described. An overview of the new model of integrated care is provided.FindingsThe baseline performance of the health and social care system in 2010/2011 is compared with the projected future performance in 2014/2015 and the current performance in 2012/2013. Reasons for underperformance of the new model of care are listed. It is concluded that integration will improve the effectiveness of care and the patient experience but is unlikely to deliver material savings. Service integration requires pump priming monies and short‐term double running costs, the close involvement of GPs and a robust change management approach.Practical implicationsThe implication of these conclusions is that the current emphasis on the cost benefits of service integration have been overstated and the difficulties of maximising cost and quality benefits underestimated.Originality/valueThe paper provides a “real world” contribution to what remains a live debate amongst NHS clinicians and managers, and those with an interest in policy development and analysis.
Integrating housing with care for older people
Authors: Blood Imogen 
Published: August 2013

PurposeThe research explored the way in which different services, providers and other key players work together in housing with care (HWC) schemes and the impact of this on the quality of life of the older people living in them, especially those with high support needs.MethodsThis qualitative study included interviews with 47 residents and five relatives at 19 private and not‐for‐profit schemes across the UK and 52 professionals from provider, statutory and other relevant organisations.FindingsMost participants were very satisfied with the services in HWC but a third described problems linked to “boundary” issues, where gaps, delays or confusion had arisen at the interface between teams, organisations or professional groups. Gaps often occurred where tasks were relatively small: they affected the quality of life of older people with high support needs but did not necessarily outweigh the benefits of living in HWC.Practical implicationsWe identify ways of improving integrated working in HWC and beyond. The paper is relevant to those commissioning and providing services to older people and to all those with an interest in integrating care and housing.Originality/valueThis is the first UK‐wide, cross‐sector study to focus specifically on the boundaries between roles and responsibilities and their impact on residents in HWC.
Forensic rehabilitation in Asperger syndrome: a case report
Authors: Kelbrick Marlene , Radley Jane 
Published: August 2013

PurposePeople with Asperger syndrome are at increased risk of co‐morbid mental health problems. The core features underlying autism are likely to play an important role in offending behaviour amongst this population. Forensic rehabilitation includes a multidisciplinary approach and combination of therapeutic interventions. However there is limited evidence in the literature of what constitutes effective treatment within this setting, and how the process of rehabilitation is experienced by patients. The purpose of this paper is to describe a case of Asperger syndrome with co‐morbid psychosis and offending behaviour and the process of forensic rehabilitation.Design/methodology/approachThe authors briefly review the literature related to Asperger syndrome, offending in this population and co‐morbidity. The authors then describe and reflect on a case of a young man with Asperger syndrome, sexual offending and the process of forensic rehabilitation, and offer an insight from the patient's perspective.FindingsCo‐morbid mental illness, when detected early, can be successfully managed with limited additional disability. The process of forensic rehabilitation includes a multidisciplinary approach. Therapeutic interventions specifically aimed at addressing core features of autism, risk and offence‐related factors are effective in promoting recovery amongst those with autism and offending behaviour.Originality/valueThe paper highlights how core features of autism can lead to offending behaviour, the importance of early recognition and treatment of co‐morbidity, and the process of forensic rehabilitation and recovery. Also included are quotes from the patient's perspective on what it is like to have Asperger syndrome, and what has been the key learning from the rehabilitation process.
Moments of identity formation and reformation: a day in the working life of an academic
Authors: Winkler Ingo 
Published: August 2013

PurposeThe purpose of the article is to illuminate micro‐processes and dynamics of identity work in an academic working context. It elaborates on the various and shifting self‐notions experienced within a typical workday of an academic.Design/methodology/approachThe study adopts an analytic autoethnographic approach focusing on recalled experiences of the author's current employment in a university department. This approach is considered to contribute to the investigation of the intensive personal process of identity construction that likewise enhances the understanding of the connection between the individual person and the organization.FindingsIllustrating the multifold notions of who one is in a particular work situation, the author demonstrates that identity work is correspondingly ongoing during the workday. Employing a workday narrative and the different self‐notions created throughout this day, the study illustrates the richness and variety in the identity work accomplished. Focusing on four particular workday events demonstrates how these situations serve as moments of identity work in the sense that they call for engaging in answering the question of who one is and how one should act.Originality/valuePromoting a micro‐perspective, the study illuminates that identity work‐processes can also be observed within the relatively small‐scaled focus of an individual workday. It proposes to understand identity work as a process of micro‐level sensemaking. The study also reveals the shifting nature of self‐notions experienced over the day. It is not only various identities that are manufactured in relation to different workday events but also that these senses of oneself come at different levels of concreteness.
