Authors: Polzin Christian , Spath Sebastian , Seitz Hermann 
Published: January 2013

PurposeThe purpose of this paper is to characterize and evaluate a new 3D‐printing process based on Poly(methyl methacrylate) (PMMA).Design/methodology/approachA benchmark part and standard parts were designed, printed by a 3D‐printer and characterized.Findings3D printed PMMA parts have a tensile strength of 2.91 MPa and a modulus of elasticity of 223 MPa. The mechanical properties can be improved by infiltrations with epoxy (tensile strength: 26.6 MPa, modulus of elasticity: 1,190 MPa). The surface quality of the parts can be improved by infiltration with wax for usage as lost models. The minimum feature size is 0.3 mm.Research limitations/implicationsThe PMMA‐based 3D printing process can be used for manufacturing concept models, functional parts and lost models for investment casting.Originality/valueThis is the first paper investigating a PMMA‐based 3D printing process.

Authors: Singh Rupinder 
Published: January 2013

PurposeFused deposition modeling (FDM) is an additive manufacturing technology commonly used for modelling, prototyping, and batch production applications. The purpose of this paper is to investigate properties of plastic replicas, fabricated as small‐sized product moulds with FDM.Design/methodology/approachFrom the identification of component, prototypes of ABS plastic material were prepared for commercial end‐user applications, such as vacuum moulding, vacuum casting, investment casting, etc.FindingsThe study highlighted the best settings of orientation and support material quantity for the selected component on FDM machine, from the dimensional accuracy and economic points of view.Originality/valueFinal replicas prepared are acceptable as per DIN 16901 and ISO (UNI EN 20286‐I‐1995) standard for industrial applications. The results are also supported by SEM analysis.
Legally scored

Published: January 2013

PurposeAchieving equal treatment of credit applicants has been a legitimate concern of legislators and the credit industry. However, measures taken to date in attempting to comply with anti‐discrimination laws arguably do not allow for the most effective use of credit scoring models, and could run counter‐intuitive to the intention of legislation through indirect discrimination. The purpose of this paper is to offer an alternative interpretation that preserves the intention of legislation and also retains the integrity and effectiveness of credit scoring models.Design/methodology/approachThe paper makes a legal analysis of anti‐discrimination laws in the UK, with US law as a comparison, aiming to demonstrate that concerns in using information protected under anti‐discrimination laws as variables may be misplaced, because nothing in these laws precludes the inclusion of all relevant variables in modelling.FindingsThe inclusion of variables representing protected characteristics in credit scoring models may not contradict current anti‐discrimination laws.Research limitations/implicationsLimitations exist from the perspectives of customer relationship and the need for further checks and balances. Conclusive validation of the findings will need to come from the courts. The paper provides a springboard for empirical research on whether the inclusion of variables representing protected characteristics in credit scorecards continues to produce better decision‐making models.Practical implicationsThe findings benefit credit risk modelling as a whole in facilitating the development of credit scorecards that are in compliance with anti‐discrimination laws, without sacrificing their effectiveness.Originality/valueThe paper presents a fresh perspective and alternative solution to legal concerns regarding the use of protected characteristics in credit scoring, which will be useful to the credit industry.
Managing compliance risk after MiFID
Authors: Musile Tanzi Paola , Gabbi Giampaolo , Previati Daniele , Schwizer Paola 
Published: January 2013

PurposeThe purpose of this paper is to focus on changes in the compliance function within major European banks and other financial intermediaries and on the effects of Markets in Financial Instruments Directive (MiFID) implementation.Design/methodology/approachThe four areas of research seek to answer the following questions: Is the positioning of the compliance function “at the top” of the organizational structure? Are the roles attributed to the compliance function, their knowledge and their instruments consistent with their responsibilities? Do the methodologies applied follow a qualitative and/or a quantitative approach? Is the interaction between the compliance function inside and outside the structure appropriate to the goals of compliance? In total, 31 top international groups based in Europe were invited to take part in the research, 16 of them accepted.FindingsThe authors observed a resolute adjustment to the regulations in terms of macrostructure and high levels of compliance function competences in investment services and business knowledge, with a low variation. The encouraging news coming out of the results of the research is the confirmation of the presence of a connection between the compliance function and both the system of values and of incentives.Originality/valueThe paper's international sample offers a unique opportunity to highlight the critical areas of the compliance function within international groups, with growing operational complexity in a framework of principle‐based regulation.
Business value of RFID‐enabled healthcare transformation projects
Authors: Anand Abhijith , Fosso Wamba Samuel 
Published: January 2013

PurposeThis paper aims to assess the business value realised from radio frequency identification (RFID)‐enabled healthcare transformation projects as compared with other industries. The paper starts with a review of RFID technology in the healthcare industry and further extends to an in‐depth analysis of mini‐case studies collected from RFID Journal, a leading professional journal dedicated to RFID technology, in order to identify the major benefits of the implementation of RFID systems as well as its business value achieved. In addition, there is further analysis that is being carried out on other industries to have an overview of the benefits of RFID implementation.Design/methodology/approachKey findings on RFID systems are being obtained from a thorough review of case studies collected from the RFID Journal's database – which for this purpose, provided 20 cases from the healthcare industry and 49 cases from other industries – so as to assess the business value of RFID‐enabled healthcare transformation projects.FindingsImplementation of RFID systems in healthcare resulted in enhanced automational, informational and transformational effects that helped to eliminate paper‐based processes, manual processes and low visibility of patients, staff, equipments and data, etc. Such a transformation definitely gave rise to high financial performances, patient satisfaction and better decision quality on their treatments, which in turn provided a high control, co‐ordination and planning of the healthcare organisation. Further, the results showcase the business value of RFID technology and the benefits gained within the healthcare sector, in comparison with other industries. Overall, this case analysis has indicated that implementation of RFID clearly produced evident effects at the process level of an organisation, thus leading to substantial gains at the organisational level.Originality/valueThis paper delivers a review of case studies on RFID‐enabled transformation projects and process innovations, mainly in the healthcare industry, albeit it extends to other industries. For this reason, a review on RFID technology is being discussed while 69 cases are being scrutinised. The results from this paper therefore provide significant evidence of RFID‐enabled healthcare and organisational business value.
Adult safeguarding and the role of housing
Authors: Parry Imogen 
Published: January 2013

PurposeThe purpose of this paper is to identify and encourage good practice in adult safeguarding by housing providers, despite their unclear and largely unregulated role in this area.Design/methodology/approachLiterature search on policy and research on the role of housing in adult safeguarding. Good practice search, drawn from No Secrets consultation responses and more recently, from other housing providers.FindingsDespite the current weak incentives for housing providers to engage in adult safeguarding, some have done so effectively, overcoming barriers to joint working.Research limitations/implicationsThis is not a comprehensive study of all good practice in this area; much will exist “unsung” and unrecognised.Practical implicationsIncrease housing providers' involvement in adult safeguarding.Originality/valueThe paper is of value, as there is a dearth of literature on the role and potential of housing and adult safeguarding.
The value added of hedge fund styles in multi‐asset portfolios
Authors: Heidorn Thomas , Kaiser Dieter , Lucke Daniel 
Published: January 2013

PurposeAcademic research has shown that diversification today may not only include stocks and bonds but also alternative investments like hedge funds. However, practical and effective methods to identify the hedge fund styles that really enhance the risk return characteristics of a traditional portfolio as well as optimal allocation sizes are not available. The aim of the paper is to try to close this gap by proposing a portfolio optimization approach based upon the traditional market exposures of the different hedge fund strategies.Design/methodology/approachFor this purpose, the paper first measures the bull and bear market betas of the main hedge fund strategies (equity market neutral, event driven, global macro, relative value, and managed futures). Based on the strategy characteristics, the authors then develop a systematic framework that calculates what percentage of each basic asset should be substituted for by hedge fund strategies to achieve the maximum results. The paper uses hedge fund index data from Hedge Fund Research and Barclay Hedge for the January 1999‐April 2011 sample period.FindingsThe empirical results show that this approach leads to an improvement in the annualized return of the optimized portfolio.Originality/valueThe paper adds to the existing literature by showing that it is possible to substitute traditional assets with hedge fund indices based on their exposures (beta) in varying market environments as a way to optimize the overall portfolio.
Analyst coverage and types of institutional investors
Authors: Chan Kam C. , Zhang Feida , Zhang Weining 
Published: January 2013

PurposeThe purpose of this paper is to study the relationship between institutional holdings and analyst coverage in the context of the heterogeneous nature of institutional investors.Design/methodology/approachSimilar to prior studies (e.g. Ke and Ramalingegowda; Ramalingegowda and Yu), this paper obtains institutional investors' trading classifications (transient, dedicated, and quasi‐indexing) from Brian Bushee directly. To examine the hypotheses, the paper uses a two‐step instrumental variable approach demonstrated in O'Brien and Bhushan to mitigate the simultaneity relationship between the change in analyst coverage and the change in the number of heterogeneous institutional investors.FindingsThe findings suggest that such relations are different among transient, dedicated, and quasi‐indexing institutional investors. Specifically, there are three major results. First, a change to the number of analyst coverage has the lowest impact on the change in the number of dedicated institutional investors. Second, a change in the number of transient institutional investors has a higher impact on change in analyst coverage than those for change in the number of dedicated and quasi‐indexing institutional investors. Third, changes to analysts' buy or sell recommendations have the least impact on the change in the number of dedicated institutions, relative to transient and quasi‐indexing institutions.Research limitations/implicationsThe findings suggest that institutional investors are not homogeneous. Research studies on institutional investors need to disentangle the differences among different types of institutions.Originality/valueThe paper provides a comprehensive study on different institutional investors and analyst coverage. The findings show the complex nature of the interaction between institutional investors and analyst coverage.

Electronic health records
Authors: Otto Peter , Nevo Dorit 
Published: January 2013

PurposeThe purpose of this paper is to understand one aspect of electronic health record adoption by studying the impact of policy interventions on the adoption among hospitals, physicians and patients, using a system dynamics simulation model.Design/methodology/approachA system dynamics simulation model of the existing distribution network was built. Policy experiments were conducted to compare the performance of each.FindingsUsing data from the Greater Capital Region, Northern New York State, the findings from the simulation experiments suggest that while there is no single right intervention, a combination of measures can promote the adoption of electronic health records by different stakeholders.Research limitations/implicationsThe results are based on simplified operational and structural assumptions regarding the diffusion of electronic health records among stakeholder groups. Some of the variables are based on theoretical rather than quantifiable values.Social implicationsThe results of this study have practical implications when it comes to designing effective policies to improve the adoption rate of electronic health records. The theoretical contribution will help stakeholders to take leadership roles in policy discussion.Originality/valueThis paper is a theoretical study describing a unique application of simulation methods to an important area of application. Use and evaluation for model‐based approaches could provide additional insight about the potential value of simulation for social learning and effective approaches to making public policy decisions.
Examining price promotions, venue and place of residence as predictors of alcohol consumption
Authors: Raciti Maria , O'Hara Rebecca , Sharma Bishnu , Reinhard Karin , Davies Fiona 
Published: January 2013

PurposeThe purpose of this study is to understand the effect of price promotions, venue and place of residence on low‐risk, risky and high‐risk alcohol consumption behaviour of young women between 18 and 24 years of age who attend university in Australia, Wales and Germany.Design/methodology/approachThe quantitative, self‐administered questionnaire collected data from a convenience sample of three universities in three OECD countries with high alcohol consumption being: a regional Australian university (n=305), a city Welsh university (n=354) and a rural German university (n=325).FindingsFirst, the multinomial logistic regression results revealed that price promotions and venue influenced alcohol consumption in Wales alone while place of residence influenced alcohol consumption in Australia; however, price promotions, venue and place of residence had no effect on young women attending university in Germany. Second, the binomial logistic regression results for Wales reported a sensitivity to price promotions for all three alcohol consumption risk classifications; however, location was of little consequence to risky drinkers when compared to high risk drinkers. For Australia, the place of residence did not influence alcohol consumption for both risky and high‐risk drinkers.Originality/valueThe value of this study lies in the examination of three levels of alcohol consumption – low‐risk, risky and high‐risk – for the same cohort across three countries using the same test instrument and standard alcohol consumption metrics. As such, this study provides a more meaningful macro view of alcohol consumption; thus has the capacity to contribute to effectual intervention strategies.
Colony life history and lifetime reproductive success of red harvester ant colonies
Authors: Ingram Krista K. , Pilko Anna , Heer Jeffrey , Gordon Deborah M. 
Published: January 2013

SummaryWe estimate colony reproductive success, in numbers of offspring colonies arising from a colony's daughter queens, of colonies of the red harvester ant,Pogonomyrmex barbatus.A measure of lifetime reproductive success is essential to understand the relation of ecological factors, phenotype and fitness in a natural population. This was possible for the first time in a natural population of ant colonies using data from long‐term study of a population of colonies in south‐eastern Arizona, for which ages of all colonies are known from census data collected since 1985.Parentage analyses of microsatellite data from 5 highly polymorphic loci were used to assign offspring colonies to maternal parent colonies in a population of about 265 colonies, ages 1–28 years, sampled in 2010.The estimated population growth rate Rowas 1·69 and generation time was 7·8 years. There was considerable variation among colonies in reproductive success: of 199 possible parent colonies, only 49 (˜ 25%) had offspring colonies on the site. The mean number of offspring colonies per maternal parent colony was 2·94 and ranged from 1 to 8. A parent was identified for the queen of 146 of 247 offspring colonies. There was no evidence for reproductive senescence; fecundity was about the same throughout the 25–30 year lifespan of a colony.There were no trends in the distance or direction of the dispersal of an offspring relative to its maternal parent colony. There was no relationship between the number of gynes produced by a colony in 1 year and the number of offspring colonies subsequently founded by its daughter reproductive females.The results provide the first estimate of a life table for a population of ant colonies and the first estimate of the female component of colony lifetime reproductive success. The results suggest that commonly used measures of reproductive output may not be correlated with realized reproductive success. This is the starting point for future investigation asking whether variation in reproductive success is related to phenotypic variation among colonies in behavioural and ecological traits.
Are populations of large‐bodied avian frugivores onLuzon,Philippines, facing imminent collapse?
Authors: Española C. P. , Collar N. J. , Marsden S. J. 
Published: January 2013

AbstractAvian frugivores acrossSoutheastAsia, and in thePhilippines in particular, are seriously threatened owing to massive loss of habitat and direct exploitation through hunting and the pet trade. Their declines may have dire consequences for wider ecological processes as many frugivores are also seed dispersers. Twenty‐five species of pigeons, parrots and hornbills were surveyed using distance sampling along nearly 500 km of line transects at 14 sites across the island ofLuzon. We documented surprisingly few reliable disappearances of frugivores from individual forest patches – in fact ours and other fieldwork since 2000 have increased the known extent of occurrence of several species. However, green racquet‐tailPrioniturus luconensishas been recorded at only seven out of 29 historic sites in the last 10 years; although possibly a function of poor coverage, this may be a real range contraction. Still more alarming was the absence of large parrots from most sites with apparently intact habitat surveyed. Even where present, large parrots exhibited lower densities than related species in similar habitat inSoutheastAsia. Multiplying site‐specific density estimates by reserve area, we estimated population sizes for species in five reserves selected from the current protected area network. For six species, including four of six parrots, largest populations in any reserve in Luzon numbered < 1000 individuals, and nearly one‐third of all populations in reserves were < 100. Given differing opinions and evidence on minimum viable population (MVP) thresholds, we used a range ofMVPvalues to predict the likelihood that frugivore populations will persist in various reserves. AtMVPs of 500, frugivore communities in all but 2–3 of the largest reserves are not expected to survive. Although seed dispersers may fare better than seed predators (large parrots), and many frugivores are good fliers that can disperse between widely separated sites, we express the concern that without stricter species and site protection a major collapse of frugivore communities may occur across Luzon, with serious implications for ecosystem functioning.
Intermittent access ethanol consumption dysregulates CRF function in the hypothalamus and is attenuated by the CRF‐R1 antagonist, CP‐376395
Authors: Simms Jeffrey A. , Nielsen Carsten K. , Li Rui , Bartlett Selena E. 
Published: January 2013

AbstractCorticotrophin‐releasing factor (CRF) is a mediator of stress responses and a key modulator of ethanol‐mediated behaviors. We report here that the CRF receptor 1 (CRF‐R1) antagonist, CP‐376395 reduces 20% ethanol consumption in animals trained to consume ethanol on an intermittent, but not a continuous, schedule. Furthermore, using [35S]GTPγS binding assays, we demonstrate that CRF‐mediated G‐protein signaling in the hypothalamus of the intermittent drinkers is decreased when compared to controls suggesting that the effects of CP‐376395 are mediated by extrahypothalamic mechanisms. The present study provides further support for the use of CRF‐R1 antagonists for the treatment of alcohol use disorders and suggests that ethanol consumption dysregulates CRF function in the hypothalamus.
