Experts as facilitators for the implementation of social media in the library? A social network approach
Authors: Vanwynsberghe Hadewijch , Boudry Elke , Vanderlinde Ruben , Verdegem Pieter 
Published: September 2014

Purpose– Based on the social capital theory, the authors assume that personal and professional experts are both relevant to people's competence development. However, to date, there is little empirical evidence of how professional experts can support, or impede, people in learning how to deal with social media. The purpose of this paper is to examine the role and position of social media experts in the distribution of information on social media within the library as organization.Design/methodology/approach– The paper draws upon social network and qualitative methods, within three public libraries located in Belgium.Findings– The findings suggest that as the most central actors, social media experts in a library play a significant role in either supporting or constraining the distribution of information on social media.Research limitations/implications– While the sample size was chosen to conduct a mixed methods study that would explore how the position of a social media expert in an organization such as the library facilitates or prevents the exchange of social media information, the authors acknowledge the need for large-scale empirical studies that can substantiate the findings in larger and more diverse samples.Originality/value– This unique study explores how the role and position social media experts in Belgian public libraries can support, or impede, librarians in learning how to deal with social media. This study is useful for other public libraries who want to implement social media, establish a social media policy and/or provide social media training.

Institutional repository as an important part of scholarly communication
Authors: Koler-Povh Teja , Mikoš Matjaž , Turk Goran 
Published: September 2014

Purpose
– The purpose of this paper is to present the institutional repository (IR) named DRUGG (Digital Repository of the University of Ljubljana, Faculty of Civil and Geodetic Engineering) of the University of Ljubljana, Faculty of Civil and Geodetic Engineering (UL FGG), just from its beginnings in 2011, and using the statistics of visits to present its merits for higher visibility of scholarly publications on the web. The role of all stakeholders involved in the construction of this IR is highlighted.

Design/methodology/approach
– The historical overview of the awareness of researchers on the UL FGG on worldwide scientific communication through web sites is showed from beginning in the 1990s. Using Google Analytics the statistics of visits and downloads after a year of operations is showed, as well as the statistics of access from different networks from all over the world.

Findings
– In the DRUGG repository mainly theses are archived which are usually not published elsewhere. They are very interesting for professional engineers working in practice. The statistics showed that 89 per cent of all visits come from public domains, while only 11 per cent are from the home domain of the University of Ljubljana (UL).

Research limitations/implications
– This paper is a case study and limited only to IR DRUGG. It describes the steps taken in implementing the IR considering the technological infrastructure, human resources and collaboration of the library staff with other professional and administrative faculty units.

Practical implications
– The repository is to a large extent used by the professional public and that the use is not limited only to the home institution – UL.

Originality/value
– This paper helps in planning to build an IR. It also presents an overview of worldwide research and analysis about the influence of IRs on citations of scholarly publications to convince the sceptical research policy makers.

Psychometric sifting to efficiently select the right service employees
Authors: E.G. Bateson John , Wirtz Jochen , Burke Eugene , Vaughan Carly 
Published: September 2014

Purpose
– Service employees in subordinate service roles are crucial for operational efficiency and service quality. However, the stressful nature of these roles, inappropriate hire selection, and the proliferation of job boards have created massive recruitment problems for HR departments. The purpose of this paper is to highlights the growing costs of recruiting the right candidates for service roles while offering an alternative approach to recruitment that is more efficient and effective than the traditional approach.

Design/methodology/approach
– The study offers empirical evidence of five instances in which the use of psychometric sifting procedures reduced recruitment costs, while improving the quality of the resultant hires.

Findings
– By standing the traditional recruitment process “on its head” and using psychometric tests at the start of the selection process, the recruitment process can be significantly improved. Such tests efficiently weed out unsuitable candidates before they even enter the recruitment process, leaving a smaller, better-qualified pool for possible recruitment.

Practical implications
– Firms can safely use the psychometric sifts to select applicants according to their operational efficiency, customer orientation, and overall performance. This paper illustrates the use of both traditional questionnaire measures and situational judgment tests to remove unsuitable applicants at the start of the selection process. A real-life case study suggests that such an approach increases the hiring success rate from 6:1 to 2:1. In the opening of a new supermarket by a UK group, this process saved 73,000 hours of managers’ time, representing $1.8 million savings in opening costs.

Originality/value
– The paper offers a viable cost-saving alternative to a growing problem for HR departments in service firms and provides directions for further research.
The mediating role of alliance marketing program creativity on the relationship between alliance orientation and market performance in the services industry
Authors: Kang Seongho , Hur Won-Moo , Kim Minsung 
Published: September 2014

Purpose– The purpose of this paper is to examine the validity of the already suggested positive relationship between marketing alliance orientation and market performance in a service context, and to investigate the mediating role of alliance marketing program creativity (AMPC) in the relationship in detail.Design/methodology/approach– To empirically test the hypotheses, a mail survey was conducted among firms with experience of service alliances in South Korea. A 725 research sample was selected (128 responded) from a database compiled by the Korea Investors Service-Financial Analysis System which provides comprehensive corporate and financial information on firms listed on the Korea Stock Exchange. partial least squares analysis was performed to test the hypotheses.Findings– Alliance orientation positively associated with market performance (H1), alliance orientation had a significantly positive effect on alliance marketing program meaningfulness and novelty (H2), and in turn, alliance marketing program meaningfulness and novelty had a significantly positive effect on market performance (H3). In terms of the determination of mediation type, full, or partial, the authors confirmed that the relationship between alliance orientation and market performance was fully mediated by AMPC (novelty and meaningfulness), by finding that the significantly reduced direct effect from alliance orientation to market performance in the mediation model.Research limitations/implications– Alliance marketing program meaningfulness and novelty perform the role of full mediators, implying that the meaningfulness, and novelty of AMPC are absolutely indispensable conditions in order for alliance orientation to lead market performance. Moreover, different from the previous studies, the research suggests that alliance marketing program meaningfulness and novelty are equally important antecedents of market performance.Originality/value– The positive relationship between alliance orientation and market performance in the service context was empirically tested, and the full mediating role of AMPC was confirmed. The importance of AMPC in the service context is highlighted.
Understanding the role of natural cheese calcium and phosphorous content, residual lactose and salt‐in‐moisture content on block‐type processed cheese functional properties: Cheese hardness and flowability/meltability

Published: September 2014

Four treatments of natural Cheddar cheese with two levels (high and low) of calcium (Ca) and phosphorus (P), and two levels (high and low) of residual lactose were manufactured. Each treatment was subsequently split prior to the salting step of cheese manufacturing processed and salted at two levels (high and low) for a total of eight treatments. The eight treatments included: high Ca and P, high lactose, high salt‐in‐moisture (S/M) content (HHH); high Ca and P, high lactose, low S/M (HHL); high Ca and P, low lactose, high S/M (HLH); high Ca and P, low lactose, low S/M (HLL); low Ca and P, high lactose, high S/M (LHH); low Ca and P, high lactose, low S/M (LHL); low Ca and P, low lactose, high S/M (LLH); and low Ca and P, low lactose, low S/M (LLL). After 2 months of ripening, each treatment of natural Cheddar cheese was used to manufacture processed cheese using a twin‐screw Blentech processed cheese cooker. All of the processed cheese food formulations were balanced for moisture, fat and salt. Texture and melt‐flow characteristics of the processed cheese were evaluated with different techniques, including texture profile analysis (TPA) for hardness and melt profile analysis. There was a considerable increase in cheese hardness for the processed cheeses prepared from high Ca and P content, and high S/M natural cheeses compared with low Ca and P content and low S/M natural cheeses. Moreover, definite decrease in flow rate and extent of flow was observed for processed cheeses manufactured from high Ca and P content, and high S/M natural cheeses than that of low Ca and P content and low S/M natural cheeses. No considerable trend was observed in hardness and melt‐flow characteristics for the processed cheeses manufactured from high and low residual lactose content natural Cheddar cheeses. This study strongly demonstrates that the characteristics of natural cheese (calcium and phosphorus content, lactose content and salt‐in‐moisture content) used in processed cheese manufacture have a significant impact on processed cheese functionality.
Performance of partial statistics in individual‐based landscape genetics
Authors: Kierepka E. M. , Latch E. K. 
Published: September 2014

AbstractIndividual‐based landscape genetic methods have become increasingly popular for quantifying fine‐scale landscape influences on gene flow. One complication for individual‐based methods is that gene flow and landscape variables are often correlated with geography. Partial statistics, particularly Mantel tests, are often employed to control for these inherent correlations by removing the effects of geography while simultaneously correlating measures of genetic differentiation and landscape variables of interest. Concerns about the reliability of Mantel tests prompted this study, in which we use simulated landscapes to evaluate the performance of partial Mantel tests and two ordination methods, distance‐based redundancy analysis (dbRDA) and redundancy analysis (RDA), for detecting isolation by distance (IBD) and isolation by landscape resistance (IBR). Specifically, we described the effects of suitable habitat amount, fragmentation and resistance strength on metrics of accuracy (frequency of correct results, type I/II errors and strength of IBR according to underlying landscape and resistance strength) for each test using realistic individual‐based gene flow simulations. Mantel tests were very effective for detecting IBD, but exhibited higher error rates when detecting IBR. Ordination methods were overall more accurate in detecting IBR, but had high type I errors compared to partial Mantel tests. Thus, no one test outperformed another completely. A combination of statistical tests, for example partial Mantel tests to detect IBD paired with appropriate ordination techniques for IBR detection, provides the best characterization of fine‐scale landscape genetic structure. Realistic simulations of empirical data sets will further increase power to distinguish among putative mechanisms of differentiation.
Ecologists overestimate the importance of predictor variables in model averaging: a plea for cautious interpretations
Authors: Galipaud Matthias , Gillingham Mark A. F. , David Morgan , Dechaume‐Moncharmont François‐Xavier 
Published: September 2014

Summary

Information‐theory procedures are powerful tools for multimodel inference and are now standard methods in ecology. When performing model averaging on a given set of models, the importance of a predictor variable is commonly estimated by summing the weights of models where the variable appears, the so‐called sum of weights (SW). However, SWs have received little methodological attention and are frequently misinterpreted.

We assessed the reliability of SW by performing model selection and averaging on simulated data sets including variables strongly and weakly correlated to the response variable and a variable unrelated to the response. Our aim was to investigate how useful SWs are to inform about the relative importance of predictor variables.

SW can take a wide range of possible values, even for predictor variables unrelated to the response. As a consequence, SW with intermediate values cannot be confidently interpreted as denoting importance for the considered predictor variable. Increasing sample size using an alternative information criterion for model selection or using only a subset of candidate models for model averaging did not qualitatively change our results: a variable of a given effect size can take a wide range of SW values.

Contrary to what is assumed in many ecological studies, it seems hazardous to define a threshold for SW above which a variable is considered as having a statistical effect on the response and SW is not a measure of effect size. Although we did not consider every possible condition of analysis, it is likely that in most situations, SW is a poor estimate of variable's importance.
Information diffusion and the predictability of New Zealand stock market returns
Authors: Lin Hai , Quill Daniel 
Published: September 2014

AbstractThis paper examines the impact of international predictors from liquid markets on the predictability of excess returns in the New Zealand stock market using data from May 1992 to February 2011. We find that US stock market return and VIX contribute significantly to the out‐of‐sample forecasts at short horizons even after controlling for the effect of local predictors, while the contribution by Australian stock market return is not significant. We further demonstrate that the predictability of New Zealand stock market returns using US market predictors could be explained by the information diffusion between these two countries.

Authors: Tan Xuefen , Xie Peng , Liu Jibing , Wu Huiyong , Xie Yinfa 
Published: September 2014

AbstractAimTo compare clinical outcome and safety of transcatheter arterial chemoembolization (TACE) + portal vein embolization (PVE) with TACE alone in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT).MethodsWe retrospectively collected patients of HCC with PVTT treated with TACE (5‐FU, oxaliplatin and mitomycin) or TACE + PVE (doxorubicin) between October 2000 and July 2008. Outcomes evaluated include overall survival, response to treatment and side effects.ResultsOne hundred and sixteen patients were assessed. The median follow‐up of TACE group and TACE + PVE group was 83 and 85 months, respectively. The tumor response rates were respectively 48/64 and 49/52. The 1‐, 3‐ and 5‐year overall survival rates for the TACE and TACE + PVE groups were 39/64, 16/64, 0/64 and 42/52, 19/52, 6/52 respectively (P = 0.015, 0.046 and 0.002, respectively). Three factors were shown as the risk factors which affect the survival of patients: treated by TACE + PVE or TACE; type of PVTT; and absence of cirrhosis.ConclusionTACE + PVE may be better than TACE alone to treat primary HCC with PVTT.
On the combination of species cover values from different vegetation layers
Authors: Fischer Hagen S. 
Published: September 2014

AbstractPhytosociological relevés consist of lists of species occurring on certain plots and their cover values in different vegetation layers. When combining the cover values of two layers into a unique value, the overlap between the layers must be taken into account. With two layers this can easily done by subtracting the product of the cover values from their sum. A general formula to estimate the combined cover for any number of layers, assuming independence of the layers, is presented. This is especially useful for large databases where rich data sets have to be compiled that were originally recorded from different numbers of vegetation layers.
Sharp Teeth or Empty Mouths? European Institutional Diversity and the Sector‐Level Minimum Wage Bite
Authors: Garnero Andrea , Kampelmann Stephan , Rycx François 
Published: September 2014

AbstractThe article explores the link between different institutional features of minimum wage systems and the minimum wage bite. We notably address the striking absence of studies on sectoral‐level minima and exploit unique data covering 17 European countries and information from more than 1,100 collective bargaining agreements. Results provide evidence for a neglected trade‐off: systems with bargained sectoral‐level minima are associated with higher Kaitz indices than systems with statutory floors, but also with more individuals actually paid below prevailing minima. Higher collective bargaining coverage can, to some extent, reduce this trade‐off between sharp teeth (high wage floors) and empty mouths (non‐compliance/non‐coverage).

Published: September 2014

ObjectivesTo evaluate the relationship between metabolic syndrome and the frequency and severity of lower urinary tract symptoms (LUTS).Patients and MethodsIn all, 4666 men aged 55–100 years consulting a general practitioner during a 12‐day period in December 2009 have been included in this observational study. LUTS were defined according to the International Prostate Symptom Score (IPSS) and metabolic syndrome with the National Cholesterol Education Program/Adult Treatment Panel III definition. We studied the correlation between metabolic syndrome and its individual components, and the severity of LUTS (IPSS and treatment for LUTS). Analyses were adjusted for body mass index, age, and prostate‐specific antigen level.ResultsMetabolic syndrome was reported in 51.5% of the patients and 47% were treated for LUTS. There was a significant link between metabolic syndrome and treated LUTS (P < 0.001). The risk of being treated for LUTS also increased with an increasing number of metabolic syndrome components present. Metabolic syndrome was positively correlated with the severity of the LUTS (P < 0.001) for overall IPSS and both voiding and storage scores (P < 0.001). Each component of the metabolic syndrome (except high‐density lipoprotein‐cholesterol) appeared as an independent risk factor of high IPSS and of LUTS treatment in multivariate analysis. Metabolic syndrome was positively correlated with prostate volume.ConclusionsOur results suggest a significant relationship between LUTS linked to benign prostatic hyperplasia and metabolic syndrome, in terms of frequency and severity. The risk of being treated for LUTS also increased with an increasing number of metabolic syndrome components present. The prevention of such modifiable factors by the promotion of dietary changes and regular physical activity practice may be of great importance for public health.
BNIP3 Interacting with LC3 Triggers Excessive Mitophagy in Delayed Neuronal Death in Stroke
Authors: Shi Ruo‐Yang , Zhu Sheng‐Hua , Li Victor , Gibson Spencer B. , Xu Xing‐Shun , Kong Ji‐Ming 
Published: September 2014

SummaryIntroductionA basal level of mitophagy is essential in mitochondrial quality control in physiological conditions, while excessive mitophagy contributes to cell death in a number of diseases including ischemic stroke. Signals regulating this process remain unknown. BNIP3, a pro‐apoptotic BH3‐only protein, has been implicated as a regulator of mitophagy.AimsBoth in vivo and in vitro models of stroke, as well as BNIP3 wild‐type and knock out mice were used in this study.ResultsWe show that BNIP3 and its homologue BNIP3L (NIX) are highly expressed in a “delayed” manner and contribute to delayed neuronal loss following stroke. Deficiency in BNIP3 significantly decreases both neuronal mitophagy and apoptosis but increases nonselective autophagy following ischemic/hypoxic insults. The mitochondria‐localized BNIP3 interacts with the autophagosome‐localized LC3, suggesting that BNIP3, similar to NIX, functions as a LC3‐binding receptor on mitochondria. Although NIX expression is upregulated when BNIP3 is silenced, up‐regulation of NIX cannot functionally compensate for the loss of BNIP3 in activating excessive mitophagy.ConclusionsNIX primarily regulates basal level of mitophagy in physiological conditions, whereas BNIP3 exclusively activates excessive mitophagy leading to cell death.
