Extend one's budget: buy used books
Authors: Staley Laura , Palo Eric 
Published: November 2010

PurposeMany libraries limit themselves to purchasing only new materials, assuming that used materials may be in poor condition or that the purchase process may be too difficult. This paper seeks to assess the benefits and disadvantages of purchasing used materials.Design/methodology/approachThe paper discusses Renton Technical College Library's experience with purchasing used books.FindingsBenefits of purchasing used books are: lower cost, quicker fulfillment of orders, and a wider selection of available titles. Disadvantages include: rare issues with book condition, and fewer free shipping and discount offers.Practical implicationsIncluding used books in their purchasing program can substantially expand the range and amount of materials libraries can collect.Originality/valueThis paper will be of use to any library facing budget cuts and looking for ways to continue to provide a wide variety of library materials.
Ethics and social networking sites: a disclosive analysis of Facebook
Authors: Light Ben , McGrath Kathy 
Published: November 2010

PurposeThis paper aims to provide insights into the moral values embodied by a popular social networking site (SNS), Facebook.Design/methodology/approachThis study is based upon qualitative fieldwork, involving participant observation, conducted over a two‐year period. The authors adopt the position that technology as well as humans has a moral character in order to disclose ethical concerns that are not transparent to users of the site.FindingsMuch research on the ethics of information systems has focused on the way that people deploy particular technologies, and the consequences arising, with a view to making policy recommendations and ethical interventions. By focusing on technology as a moral actor with reach across and beyond the internet, the authors reveal the complex and diffuse nature of ethical responsibility and the consequent implications for governance of SNS.Research limitations/implicationsThe authors situate their research in a body of work known as disclosive ethics, and argue for an ongoing process of evaluating SNS to reveal their moral importance. Along with that of other authors in the genre, this work is largely descriptive, but the paper engages with prior research by Brey and Introna to highlight the scope for theory development.Practical implicationsGovernance measures that require the developers of social networking sites to revise their designs fail to address the diffuse nature of ethical responsibility in this case. Such technologies need to be opened up to scrutiny on a regular basis to increase public awareness of the issues and thereby disclose concerns to a wider audience. The authors suggest that there is value in studying the development and use of these technologies in their infancy, or if established, in the experiences of novice users. Furthermore, flash points in technological trajectories can prove useful sites of investigation.Originality/valueExisting research on social networking sites either fails to address ethical concerns head on or adopts a tool view of the technologies so that the focus is on the ethical behaviour of users. The authors focus upon the agency, and hence the moral character, of technology to show both the possibilities for, and limitations of, ethical interventions in such cases.
Entrepreneurship education and plagiarism: tell me lies, tell me sweet little lies
Authors: O'Dwyer Michele , Risquez Angelica , Ledwith Ann 
Published: November 2010

PurposeThis paper seeks to contribute to entrepreneurship education research by exploring entrepreneurship students' views of plagiarism, and their ability to recognise and avoid plagiarism.Design/methodology/approachThe study is based on a questionnaire administered to 205 undergraduate university entrepreneurship students, combining self‐reported data with behavioural measures.FindingsThe results illustrate that, although entrepreneurship students have a clear conceptual understanding of plagiarism and how to avoid it, and they demonstrate an ability to accurately recognise material which needs to be referenced, they do not see use of non‐referenced material as being in breach of academic guidelines. The students also perceive lecturers to be more concerned with plagiarism than the students themselves or the university.Research limitations/implicationsThe research identifies a clear divergence between students' claims about their ethical stance regarding plagiarism and their ability to recognise it as a breach of academic guidelines.Practical implicationsThe practical implications for entrepreneurship education are: first, the university needs to emphasise to entrepreneurship students that plagiarism is a breach of academic guidelines which will be treated as a serious offence. Second, the university, in partnership with lecturers, must adopt experiential learning approaches to improve plagiarism avoidance skills.Originality/valueThe study supports previous research which identified that students held strong ethical views regarding plagiarism and claimed not to engage in it. However, this paper highlights the divergence between these claims and the students' ability to recognise plagiarism as a breach of academic guidelines – thereby highlighting the need to enhance academic guidelines on plagiarism.

Authors: Cunha de Azambuja Marcelo , Fernando Jung Carlos , Schwengber ten Caten Carla , Passuelo Hessel Fabiano 
Published: November 2010

PurposeThe purpose of this paper is to present the results of an analytical and experimental research for the development of an innovative product designated RFID environment (RFID‐Env). This software is designed for the use of professionals in computer systems and plant engineering who are engaged in research and development (R&D) of ultra high frequency (UHF) passive radio frequency identification (RFID) systems as applied to the management and operation of logistic supply chains.Design/methodology/approachThe RFID‐Env makes it possible to simulate on computer screens a complete RFID‐Env by processing user data on the technical and physical characteristics of real or virtual RFID‐Envs. Information outputted can include descriptions of the performance to be expected from a given configuration and detailed reports as to whether that particular configuration will succeed in reading all the RFID tags flowing through a defined system.FindingsThe paper shows the models and methods on how these simulations can be performed, and this is the major scientific contribution of this work, i.e. what are the logical and physical models that enable the development of software simulators for RFID‐Envs.Research limitations/implicationsThis work will be continued to introduce more consideration of the physical environment, such as the interferences produced by the tagged products themselves by scattering the radio frequency (RF) signals, and the models, positioning and focusing of the antennas. New RF prediction models shall be created along the continuation of this paper, with the purpose to rise the amount of environments that can be simulated.Practical implicationsThe product is intended for use by developers in computer sciences, and by engineers doing R&D for the solution of RFID problems, and makes it possible to simulate a complete range of virtual RFID‐Envs so that R&D can proceed in a non‐factory atmosphere.Originality/valueThere are only a few related papers that consider in an isolated form some of the problems approached here, but it was not found models that proposed as an integrated form all the processing to an RFID‐Env simulation like here presented.
Applying artefact‐based criteria to the recognition of “organisational” assets
Authors: El‐Tawy Nevine , Tollington Tony 
Published: November 2010

PurposeThe purpose of this paper is to present asset recognition criteria based on the idea that an asset should be functional, separable and measurable and that financial recognition should be triggered by the recognition of an artefact.Design/methodology/approachCriteria is applied to four organisational assets, that is, those intangible assets that are unlikely to be reported in the accounting domain.FindingsThe criteria is applied in order to show how one may expand the basis on which assets can be reported financially to elements of intellectual capital as well as financial capital.Originality/valueArtefact‐based asset recognition criteria could be a conduit through which intellectual capital could enter the accounting domain, a domain dominated by the maintenance of financial capital, not intellectual capital.
Public REITs' governance and regulatory structure: effects on NAV discount
Authors: Biasin Massimo , Giacomini Emanuela , Grazia Quaranta Anna 
Published: November 2010

PurposeThe purpose of this paper is to investigate the influence of the Italian real estate investment trusts (REITs)' governance and regulatory structure on the market prices discount to net asset values (NAV).Design/methodology/approachThe hypothesis is that the overall regulatory design and the rules for prudential vigilance (i.e. governance rights, closed‐end form, leverage constraints, and mandatory listing) influence REITs' share value, both as market price and as NAV). In particular, the analysis focuses on the effects of the recent introduction of a shareholders' meeting in the articles of association of newly established REITs that pursues a better alignment of interests between managers and shareholders.FindingsThe original results show that the NAV discount decreases as long as time to maturity of the fund decreases. Conversely, the NAV discount is negatively affected by share turnover (as a proxy of the liquidity generated by the mandatory listing provision) and leverage. The regulatory provision of a shareholders' meeting appears to have improved the investors' governance capability having a positive impact on the NAV discount. The different sensitivity of market prices and NAVs to the regulatory variables investigated suggests the need to consider this dichotomy when defining or amending the regulatory set ruling REITs' operations and market dynamic.Originality/valueThis paper is the first in the Italian context to specifically consider the effect of the regulatory environment on the NAV discount. In particular, the effect of the regulatory provision of a shareholders' meeting has never been investigated before.
Measuring price dynamics: evidence from the Warsaw housing market
Authors: Widłak Marta , Tomczyk Emilia 
Published: November 2010

PurposeThe aim of this paper is to present estimation results of hedonic price models as well as housing price indices for the Warsaw secondary market.Design/methodology/approachThree direct methods of constructing a hedonic price index and four indices that allow for quality adjustment are presented. The paper also discusses theoretical issues related to the estimation and interpretation of hedonic models.FindingsIt is shown that the imputation and the time dummy variable indices are subject to less variation than the characteristic price index. It is also shown that in comparison to the mean and the median, hedonic indices are less variable, which can be interpreted as partial control for quality changes in dwellings sold.Practical implicationsAs this research project represents one of the first attempts of hedonic modelling applied to the Polish housing market, its results may be employed by appraisers to gain insight into behaviour of the Warsaw housing market. Practical implications focus on reliable measurement of house price dynamics in Poland. This paper supplies an appropriate methodology for addressing this question and offers empirical solutions.Originality/valueEmployment of hedonic models for construction of quality‐adjusted housing price indices has not yet been explored in Poland. The theoretical and practical aspects of hedonic indices presented in the paper open promising directions for the development of Polish statistics of real estate prices.
Use of vibration measurements in health monitoring of reinforced concrete buildings
Authors: Kanwar Varinder S. , Kwatra Naveen , Aggarwal Pankaj , Singh Ramesh P. 
Published: November 2010

PurposeIn developing countries such as India, it is common practice to use low‐quality building materials, the strength of such materials reduce with time, which affects the lifespan of buildings. The wind, rain, seepage, and surface runoff are other key factors responsible for building damage and exterior degradation. The increasing industrial growth in and around urban areas is responsible for increasing industrial and anthropogenic emissions that are found to accelerate degradation of the buildings that affects their physical appearance. In an area prone to natural hazards such as earthquakes, volcanoes, subsidence, floods, lightning, tornados, and cyclone/hurricanes, huge amounts of damage throughout the globe has been experienced. For the purpose of assuring safety due to natural hazards, it is necessary to monitor the damage for its existence, its location and extent. Undetected damage may potentially lead to risk of vulnerability caused by natural hazards and eventually to catastrophic failure. Hence, rapid structural damage detection is essential and important to save human life due to failure of structures or buildings. Most of the time, human loss occurs due to damage to the buildings. This paper aims to address these issues.Design/methodology/approachIn the present study, numerous experiments have been carried out on two reinforced concrete building test specimens and on seven existing reinforced cement concrete structures.FindingsThe results presented here in this study show that the vibration measurements can be used to monitor the health of framed reinforced cement concrete buildings.Originality/valueThe present study is part of doctoral thesis of Varinder S. Kanwar, an original research work.
Nucleotide variability of the porcine SERPINA6 gene and the origin of a putative causal mutation associated with meat quality
Authors: Esteve A. , Ojeda A. , Huang L. S. , Folch J. M. , Pérez‐Enciso M. 
Published: November 2010

SummaryThe serpin peptidase inhibitor, clade A, member 6 gene (SERPINA6), also known as corticosteroid‐binding globulin or CBG, is involved in obesity and stress sensitivity. Previous studies have reported putative causal mutations within that gene in the porcine species. To characterize a hypothetical selective footprint, we have resequenced approximately 6 kb of coding and non‐coding fragments in 20 pigs comprising domestic breeds and wild boars from Asia and Europe. Nucleotide variability was found to be far greater within Asian pig breeds than European breeds (π = 1% vs. 0.05%, respectively), which is consistent with pig evolutionary history. The putative causal amino acid substitution p.Gly307Arg (SNP c.919G>A) associated with meat quality (drip loss) was only detected in European domestic pig breeds, suggesting a very recent mutation that appeared after domestication in Europe. No support for positive selection was detected, as no reduction in levels of diversity surrounding the mutation was found in lean breeds with respect to wild boar.
The effect of unions on the distribution of wages of hospital‐employed registered nurses in the United States
Authors: Spetz Joanne , Ash Michael , Konstantinidis Charalampos , Herrera Carolina 
Published: November 2010

Aims and objectives.  We estimate the impact of unionisation on the wage structure of hospital‐employed registered nurses in the USA. We examine whether unions have an effect on wage differences associated with race, gender, immigration status, education and experience, as well as whether there is less unexplained wage variation among unionised nurses.Background.  In the past decade, there has been resurgence in union activity in the health care industry in the USA, particularly in hospitals. Numerous studies have found that unions are associated with higher wages. Unions may also affect the structure of wages paid to workers, by compressing the wage structure and reducing unexplained variation in wages.Design.  Cross‐sectional analysis of pooled secondary data from the United States Current Population Survey, 2003–2006.Method.  Multivariate regression analysis of factors that predict wages, with models derived from labour economics.Results.  There are no wage differences associated with gender, race or immigration status among unionised nurses, but there are wage penalties for black and immigrant nurses in the non‐union sector. For the most part, the pay structures of the union and non‐union sectors do not significantly differ. The wage penalty associated with diploma education for non‐union nurses disappears among unionised nurses. Unionised nurses receive a lower return to experience, although the difference is not statistically significant. There is no evidence that unexplained variation in wages is lower among unionised nurses.Conclusions.  While in theory unions may rationalise wage‐setting and reduce wage dispersion, we found no evidence to support this hypothesis.Relevance to clinical practice.  The primary effect of hospital unions is to raise wages. Unionisation does not appear to have other important wage effects among hospital‐employed nurses.
An essential Aurora‐related kinase transiently associates with spindle pole bodies during Plasmodium falciparum erythrocytic schizogony
Authors: Reininger Luc , Wilkes Jonathan M. , Bourgade Hélène , Miranda‐Saavedra Diego , Doerig Christian 
Published: November 2010

SummaryAurora kinases compose a family of conserved Ser/Thr protein kinases playing essential roles in eukaryotic cell division. To date, Aurora homologues remain uncharacterized in the protozoan phylum Apicomplexa. In malaria parasites, the characterization of Aurora kinases may help understand the cell cycle control during erythrocytic schizogony where asynchronous nuclear divisions occur. In this study, we revisited the kinome of Plasmodium falciparum and identified three Aurora‐related kinases, Pfark‐1, ‐2, ‐3. Among these, Pfark‐1 is highly conserved in malaria parasites and also appears to be conserved across Apicomplexa. By tagging the endogenous Pfark‐1 gene with the green fluorescent protein (GFP) in live parasites, we show that the Pfark‐1–GFP protein forms paired dots associated with only a subset of nuclei within individual schizonts. Immunofluorescence analysis using an anti‐α‐tubulin antibody strongly suggests a recruitment of Pfark‐1 at duplicated spindle pole bodies at the entry of the M phase of the cell cycle. Unsuccessful attempts at disrupting the Pfark‐1 gene with a knockout construct further indicate that Pfark‐1 is required for parasite growth in red blood cells. Our study provides new insights into the cell cycle control of malaria parasites and reports the importance of Aurora kinases as potential targets for new antimalarials.
Characterization of Helicobacter pylori factors that control transformation frequency and integration length during inter‐strain DNA recombination
Authors: Humbert Olivier , Dorer Marion S. , Salama Nina R. 
Published: November 2010

Summary Helicobacter pylori is a genetically diverse bacterial species, owing in part to its natural competence for DNA uptake that facilitates recombination between strains. Inter‐strain DNA recombination occurs during human infection and the H. pylori genome is in linkage equilibrium worldwide. Despite this high propensity for DNA exchange, little is known about the factors that limit the extent of recombination during natural transformation. Here, we identify restriction‐modification (R‐M) systems as a barrier to transformation with homeologous DNA and find that R‐M systems and several components of the recombination machinery control integration length. Type II R‐M systems, the nuclease nucT and resolvase ruvC reduced integration length whereas the helicase recG increased it. In addition, we characterized a new factor that promotes natural transformation in H. pylori, dprB. Although free recombination has been widely observed in H. pylori, our study suggests that this bacterium uses multiple systems to limit inter‐strain recombination.
Soluble CD26 / Dipeptidyl Peptidase IV Enhances Human Lymphocyte Proliferation In Vitro Independent of Dipeptidyl Peptidase Enzyme Activity and Adenosine Deaminase Binding

AbstractHuman CD26 has dipeptidyl peptidase‐4 (DPP IV) enzyme activity and binds to adenosine deaminase (ADA). CD26 is costimulatory for lymphocytes and has a circulating soluble form (sCD26). DPP IV enzyme inhibition is a new successful type 2 diabetes therapy. We examined whether the ADA binding and catalytic functions of sCD26 contribute to its effects on T‐cell proliferation. Wildtype soluble recombinant human CD26 (srhCD26), an enzyme inactive mutant (srhCD26E‐) and an ADA non‐binding mutant (srhCD26A‐) were co‐incubated in in vitro T‐cell proliferation assays with peripheral blood mononuclear cells (PBMC) stimulated with phytohaemagglutinin (PHA), muromonab‐CD3 or Herpes simplex virus antigen (HSV Ag). Both srhCD26 and srhCD26E‐ enhanced PHA‐induced T‐cell proliferation dose‐dependently in all six subjects tested. srhCD26 and srhCD26A‐ had no overall effect on anti‐CD3‐stimulated PBMC proliferation in four of five subjects. srhCD26, srhCD26E‐ and srhCD26A‐ enhanced HSV Ag induced PBMC proliferation in low responders to HSV Ag, but had no effect or inhibited proliferation in HSV‐high responders. Thus, effects of soluble human CD26 on human T‐cell proliferation are mechanistically independent of both the enzyme activity and the ADA‐binding capability of sCD26.

Published: November 2010

AbstractBackground and Aim:  Insulin resistance and diabetes mellitus (DM) are known to contribute to the progression of non‐alcoholic fatty liver disease (NAFLD). However, the relationship between glucose metabolism and NAFLD is not well known. In this study, we investigated whether secretion patterns of glucose and insulin could influence the histological severity in NAFLD patients without prior known type 2 DM.Methods:  A 75‐g glucose tolerance test was performed on 173 biopsy‐proven NAFLD patients without prior known type 2 DM. Plasma glucose and insulin levels were analyzed periodically for 3 h after oral glucose loading.Results:  Of the 173 NAFLD patients, 168 had non‐alcoholic steatohepatitis, whereas no patient had cirrhosis. Irrespective of the hemoglobin A1c levels, impaired glucose tolerance, including DM, was detected in 60% of the NAFLD patients. While the secretion pattern of glucose after glucose loading was similar among the NAFLD patients, postprandial insulin levels increased and delayed insulin secretion increased in severity in parallel with the aggravation of histological findings (fibrosis stages). Factors associated with advanced fibrosis were higher insulin levels at 120 min after oral glucose loading (P = 0.0001; odds ratio [OR], 3.56; 95% confidence interval [CI], 1.61–7.86), aspartate aminotransferase (P = 0.003; OR, 2.70; 95% CI: 1.19–6.12), and age (P = 0.02; OR, 2.49; 95% CI: 1.15–5.37) as determined by multivariate analysis.Conclusions:  Postprandial hyperinsulinemia (but not glucose levels) was associated with advanced fibrosis. The oral glucose tolerance test should be considered in NAFLD patients without prior known type 2 DM in order to facilitate early therapeutic intervention.
