Association Analysis for Bacterial Spot Resistance in a Directionally Selected Complex Breeding Population of Tomato
Authors: Sim Sung-Chur , Robbins Matthew D. , Wijeratne Saranga , Wang Hui , Yang Wencai , Francis David M.
Published: October 2015

Bacterial spot of tomato is caused by at least four species of Xanthomonas with multiple physiological races. We developed a complex breeding population for simultaneous discovery of marker-trait linkage, validation of existing quantitative trait loci (QTL), and pyramiding of resistance. Six advanced accessions with resistance from distinct sources were crossed in all combinations and their F1hybrids were intercrossed. Over 1,100 segregating progeny were evaluated in the field following inoculation with X. euvesicatoria race T1 strains. We selected 5% of the most resistant and 5% of the most susceptible progeny for evaluation as plots in two subsequent replicated field trials inoculated with T1 and T3 (X. perforans) strains. The estimated heritability of T1 resistance was 0.32. In order to detect previously reported resistance genes, as well as novel QTL, we explored methods to correct for population structure and analysis based on single markers or haplotypes. Both single-point and haplotype analyses identified strong associations in the genomic regions known to carry Rx-3 (chromosome 5) and Rx-4/Xv3 (chromosome 11). Accounting for kinship and structure generally improved the fit of statistical models. Detection of known loci was improved by adding kinship or a combination of kinship and structure using a Q matrix from model-based clustering. Additional QTL were detected on chromosomes 1, 4, 6, and 7 for T1 resistance and chromosomes 2, 4, and 6 for T3 resistance (P < 0.01). Haplotype analysis improved our ability to trace the origin of positive alleles. These results demonstrate that both known and novel associations can be identified using complex breeding populations that have experienced directional selection.
Analysis of Serial Radiographs of the Foot to Determine Normative Values for the Growth of the First Metatarsal to Guide Hemiepiphysiodesis for Immature Hallux Valgus
Authors: Greene Janelle D. , Nicholson Allen D. , Sanders James O. , Cooperman Daniel R. , Liu Raymond W.
Published: October 2015

Background:

Hallux valgus deformity in the immature patient can be difficult to manage, as osteotomy can result in recurrence with additional growth. Lateral hemiepiphysiodesis of the first metatarsal offers a promising alternative, by permitting gradual correction of the intermetatarsal angle with growth. An important limitation of this approach is the lack of normative tables of first metatarsal growth to guide timing of intervention.

Methods:

First metatarsal lengths were measured from anteroposterior foot radiographs of children. For females, 95 patients totaling 894 radiographs were used ranging from 6 months to 18 years of age. For males, 122 patients totaling 1018 radiographs were measured ranging from 8 months to 19.5 years of age. All patients with image series including a closed proximal metatarsal physis were sorted into an older group, with multipliers generated by setting last image to a multiplier of 1. Patients with serial imaging not inclusive of a closed physis were classified as a younger group, with multipliers based off of the multiplier at age 7 from the older group. First metatarsal multiplier values were then compared with published multiplier values for the overall foot.

Results:

For both females and males, the multipliers followed a logarithmic curve versus age, with R
2 values of 0.921 and 0.888, respectively. Comparison of the first metatarsal multiplier values with previously studied multiplier values of the entire foot showed high correlation with ICC=0.955 for females and ICC=0.969 for males.

Conclusions:

The pattern of growth of the first metatarsal follows a logarithmic regression curve. These normative tables allow for clinical prediction of first metatarsal remaining growth based on age and sex, and in turn guide timing of hemiepiphysiodesis for the surgical correction of hallux valgus deformity.

Clinical Relevance:

The normative tables generated in this study can be used for the calculation of hemiepiphysiodesis and the timing of intervention. Future clinical correlation studies will be important.

Published: October 2015

Cystic nephroma (CN) and mixed epithelial stromal tumor (MEST) of the kidney have been considered as synonymous terms describing a single nosologic entity in adult patients. Cystic nephroma in pediatric patients (PCN) is, apparently, a completely different nosologic entity. Although the presence of DICER 1 mutations is well established in PCN, nothing is currently known about the DICER 1 gene status in adult MEST/CN. About 33 cases of MEST/CN were selected from the Plzen Tumor Registry; 4 cases were later excluded from the study due to low DNA quality. About 28 of the studied tumors displayed a benign morphology, whereas 1 was diagnosed as a malignant MEST/CN with sarcomatoid differentiation of the stromal component. All 29 samples analyzed using polymerase chain reaction and direct sequencing, including the case with the malignant morphology, were negative for mutation in DICER 1 hot-spot codons 1705, 1709, 1809, 1810, 1813, and 1814. Our results show that MEST/CN has no relation to PCN on a molecular genetic level. On the basis of our findings and the established morphologic differences between PCN and MEST/CN, we conclude that the term CN should be used for pediatric cases only and should be avoided in adult cases of MEST.

Authors: Dutschke Jeffrey K. , Finnie John W. , Manavis Jim , Anderson Robert W.G.
Published: October 2015

Introduction:

In traumatic brain injury biomechanics, macroscale biomechanical events need to be correlated with microscale neuropathologic changes and improved quantitation of microscopic axonal injury is an essential component of lesion evaluation.

Objectives:

To develop a novel technique for automatically identifying injured amyloid precursor protein immunopositive axons and aggregating these observations over a macroscopic brain dissection.

Methods:

A color deconvolution method was adapted into Matlab to identify clusters of pixels with colors typical of amyloid precursor protein positive tissue from large-scale brain dissection.

Results:

The methodology is demonstrated in the brain of a sheep subjected to a controlled cortical indentation.

Conclusions:

The technique will be of interest to pathologists and bioengineers seeking to quantitate brain injury over macroscales.
Optimized Protocol of Methanol Treatment for Immunofluorescent Staining in Fixed Brain Slices
Authors: Yuan Feng , Xiong Guoxiang , Cohen Noam A. , Cohen Akiva S.
Published: October 2015

We optimized methanol treatment in paraformaldehyde-fixed slices for immunofluorescent staining of ependymal basal bodies in brain ventricles. As 100% methanol induced severe deformations to the slices (including rolling and folding over), we tried to decrease methanol concentration. We found that 33.3% to 75% methanol could result in ideal immunostaining of basal bodies without inducing obvious deformations. Instead of treating slices at −20°C (without proper cryoprotection measurements) as suggested in previous studies, we carried out methanol treatment at room temperature. Our modified protocol can not only raise immunostaining efficiency in tissue slices, it may also prevent potential freezing damages to the samples.

Published: October 2015

The 2014 Research Excellence Framework (REF2014) was conducted to assess the quality of research carried out at higher education institutions in the UK over a 6 year period. However, the process was criticized for being expensive and bureaucratic, and it was argued that similar information could be obtained more simply from various existing metrics. We were interested in whether a prediction market on the outcome of REF2014 for 33 chemistry departments in the UK would provide information similar to that obtained during the REF2014 process. Prediction markets have become increasingly popular as a means of capturing what is colloquially known as the ‘wisdom of crowds’, and enable individuals to trade ‘bets’ on whether a specific outcome will occur or not. These have been shown to be successful at predicting various outcomes in a number of domains (e.g. sport, entertainment and politics), but have rarely been tested against outcomes based on expert judgements such as those that formed the basis of REF2014.
Anisotropy and lack of symmetry for a random aggregate of frictionless, elastic particles: theory and numerical simulations
Authors: La Ragione L. , Oger L. , Recchia G. , Sollazzo A.
Published: October 2015

We consider a random aggregate of identical, frictionless spheres whose contact is maintained by an applied pressure. The aggregate is then subjected to an axial compression at fixed pressure. We show that the incremental elastic response of the resulting transversely isotropic material is characterized by six rather than by five independent coefficients and that the stiffness tensor does not have the major symmetry. This is because we permit deviations from an affine deformation that are determined by local equilibrium, when anisotropy is present. Discrete element numerical simulations confirm these findings.
A symplectic method for structure-preserving modelling of damped acoustic waves
Authors: Li Xiaofan , Lu Mingwen , Liu Shaolin , Chen Shizhong , Zhang Huan , Zhang Meigen
Published: October 2015

In this paper, a symplectic method for structure-preserving modelling of the damped acoustic wave equation is introduced. The equation is traditionally solved using non-symplectic schemes. However, these schemes corrupt some intrinsic properties of the equation such as the conservation of both precision and the damping property in long-term calculations. In the method presented, an explicit second-order symplectic scheme is used for the time discretization, whereas physical space is discretized by the discrete singular convolution differentiator. The performance of the proposed scheme has been tested and verified using numerical simulations of the attenuating scalar seismic-wave equation. Scalar seismic wave-field modelling experiments on a heterogeneous medium with both damping and high-parameter contrasts demonstrate the superior performance of the approach presented for suppression of numerical dispersion. Long-term computational experiments display the remarkable capability of the approach presented for long-time simulations of damped acoustic wave equations. Promising numerical results suggest that the approach is suitable for high-precision and long-time numerical simulations of wave equations with damping terms, as it has a structure-preserving property for the damping term.
Signatures of chaotic and stochastic dynamics uncovered with
ε
-recurrence networks
Authors: Subramaniyam N. P. , Donges J. F. , Hyttinen J.
Published: October 2015

An old and important problem in the field of nonlinear time-series analysis entails the distinction between chaotic and stochastic dynamics. Recently,
ε
-recurrence networks have been proposed as a tool to analyse the structural properties of a time series. In this paper, we propose the applicability of local and global
ε
-recurrence network measures to distinguish between chaotic and stochastic dynamics using paradigmatic model systems such as the Lorenz system, and the chaotic and hyper-chaotic Rössler system. We also demonstrate the effect of increasing levels of noise on these network measures and provide a real-world application of analysing electroencephalographic data comprising epileptic seizures. Our results show that both local and global
ε
-recurrence network measures are sensitive to the presence of unstable periodic orbits and other structural features associated with chaotic dynamics that are otherwise absent in stochastic dynamics. These network measures are still robust at high noise levels and short data lengths. Furthermore,
ε
-recurrence network analysis of the real-world epileptic data revealed the capability of these network measures in capturing dynamical transitions using short window sizes.
ε
-recurrence network analysis is a powerful method in uncovering the signatures of chaotic and stochastic dynamics based on the geometrical properties of time series.
On the wave propagation in the time differential dual-phase-lag thermoelastic model
Authors: Chiriţă Stan , Ciarletta Michele , Tibullo Vincenzo
Published: October 2015

We study the propagation of plane time harmonic waves in the infinite space filled by a time differential dual-phase-lag thermoelastic material. There are six possible basic waves travelling with distinct speeds, out of which, two are shear waves, and the remaining four are dilatational waves. The shear waves are found to be uncoupled, undamped in time and travels independently with the speed that is unaffected by the thermal effects. All the other possible four dilatational waves are found to be coupled, damped in time and dispersive due to the presence of thermal properties of the material. In fact, there is a damped in time longitudinal quasi-elastic wave whose amplitude decreases exponentially to zero when the time is going to infinity. There is also a quasi-thermal mode, like the classical purely thermal disturbance, which is a standing wave decaying exponentially to zero when the time goes to infinity. Furthermore, there are two possible longitudinal quasi-thermal waves that are damped in time with different decreasing rates or there is one plane harmonic in time longitudinal thermal wave, depending on the values of the time delays. The surface wave problem is studied for a half space filled by a dual-phase-lag thermoelastic material. The surface of the half space is free of traction and it is free to exchange heat with the ambient medium. The dispersion relation is written in an explicit way and the secular equation is established. Numerical computations are performed for a specific model, and the results obtained are depicted graphically.
Analyses of postbuckling in stretchable arrays of nanostructures for wide-band tunable plasmonics
Authors: Shi Yan , Luo Hongying , Gao Li , Gao Cunfa , Rogers John A. , Huang Yonggang , Zhang Yihui
Published: October 2015

Plasmonic nanostructures integrated with soft, elastomeric substrates provide an unusual platform with capabilities in mechanical tuning of key optical properties, where the surface configurations can undergo large, nonlinear transformations. Arrays of planar plasmonic nanodiscs in this context can, for example, transform into three-dimensional (3D) layouts upon application of large levels of stretching to the substrate, thereby creating unique opportunities in wide-band tunable optics and photonic sensors. In this paper, a theoretical model is developed for a plasmonic system that consists of discrete nanodiscs on an elastomeric substrate, establishing the relation between the postbuckling configurations and the applied strain. Analytic solutions of the amplitude and wavelength during postbuckling are obtained for different buckling modes, which agree well with the results of finite-element analyses and experiment measurements. Further analyses show that increasing the nanodisc distribution yields increased 3D configurations with larger amplitudes and smaller wavelengths, given the same level of stretching. This study could serve as a design reference for future optimization of mechanically tunable plasmonic systems in similar layouts.

Published: October 2015

Despite increasing concerns about the vulnerability of species' populations to climate change, there has been little overall synthesis of how individual population responses to variation in climate differ between taxa, with trophic level or geographically. To address this, we extracted data from 132 long-term (greater than or equal to 20 years) studies of population responses to temperature and precipitation covering 236 animal and plant species across terrestrial and freshwater habitats. Our results identify likely geographical differences in the effects of climate change on populations and communities in line with macroecological theory. Temperature tended to have a greater overall impact on populations than precipitation, although the effects of increased precipitation varied strongly with latitude, being most positive at low latitudes. Population responses to increased temperature were generally positive, but did not vary significantly with latitude. Studies reporting significant climatic trends through time tended to show more negative effects of temperature and more positive effects of precipitation upon populations than other studies, indicating climate change has already impacted many populations. Most studies of climate change impacts on biodiversity have focused on temperature and are from middle to high northern latitudes. Our results suggest their findings may be less applicable to low latitudes.
The nature and dynamics of world religions: a life-history approach
Authors: Baumard Nicolas , Chevallier Coralie
Published: October 2015

In contrast with tribal and archaic religions, world religions are characterized by a unique emphasis on extended prosociality, restricted sociosexuality, delayed gratification and the belief that these specific behaviours are sanctioned by some kind of supernatural justice. Here, we draw on recent advances in life history theory to explain this pattern of seemingly unrelated features. Life history theory examines how organisms adaptively allocate resources in the face of trade-offs between different life-goals (e.g. growth versus reproduction, exploitation versus exploration).In particular, recent studies have shown that individuals, including humans, adjust their life strategy to the environment through phenotypic plasticity: in a harsh environment, organisms tend to adopt a ‘fast' strategy, pursuing smaller but more certain benefits, while in more affluent environments, organisms tend to develop a ‘slow' strategy, aiming for larger but less certain benefits. Reviewing a range of recent research, we show that world religions are associated with a form of ‘slow' strategy. This framework explains both the promotion of ‘slow' behaviours such as altruism, self-regulation and monogamy in modern world religions, and the condemnation of ‘fast' behaviours such as selfishness, conspicuous sexuality and materialism. This ecological approach also explains the diffusion pattern of world religions: why they emerged late in human history (500–300 BCE), why they are currently in decline in the most affluent societies and why they persist in some places despite this overall decline.
Solving the puzzle of collective action through inter-individual differences
Authors: von Rueden Chris , Gavrilets Sergey , Glowacki Luke
Published: October 2015

Models of collective action infrequently account for differences across individuals beyond a limited set of strategies, ignoring variation in endowment (e.g. physical condition, wealth, knowledge, personality, support), individual costs of effort, or expected gains from cooperation. However, behavioural research indicates these inter-individual differences can have significant effects on the dynamics of collective action. The papers contributed to this theme issue evaluate how individual differences affect the propensity to cooperate, and how they can catalyse others’ likelihood of cooperation (e.g. via leadership). Many of the papers emphasize the relationship between individual decisions and socio-ecological context, particularly the effect of group size. All together, the papers in this theme issue provide a more complete picture of collective action, by embracing the reality of inter-individual variation and its multiple roles in the success or failure of collective action.
Interactions between personality and institutions in cooperative behaviour in humans
Authors: Schroeder K. B. , Nettle D. , McElreath R.
Published: October 2015

Laboratory attempts to identify relationships between personality and cooperative behaviour in humans have generated inconsistent results. This may partially stem from different practices in psychology and economics laboratories, with both hypothetical players and incentives typical only in the former. Another possible cause is insufficient consideration of the contexts within which social dilemmas occur. Real social dilemmas are often governed by institutions that change the payoff structure via rewards and punishments. However, such ‘strong situations’ will not necessarily suppress the effects of personality. On the contrary, they may affect some personalities differentially. Extraversion and neuroticism, reflecting variation in reward and punishment sensitivity, should predict modification of cooperative behaviour following changes to the payoff structure. We investigate interactions between personality and a punishment situation via two versions of a public goods game. We find that, even in a strong situation, personality matters and, moreover, it is related to strategic shifts in cooperation. Extraversion is associated with a shift from free-riding to cooperation in the presence of punishment, agreeableness is associated with initially higher contributions regardless of game, and, contrary to our predictions, neuroticism is associated with lower contributions regardless of game. Results should lead to new hypotheses that relate variation in biological functioning to individual differences in cooperative behaviour and that consider three-way interactions among personality, institutional context and sociocultural background.
The Big Man Mechanism: how prestige fosters cooperation and creates prosocial leaders
Authors: Henrich Joseph , Chudek Maciej , Boyd Robert
Published: October 2015

Anthropological evidence from diverse societies suggests that prestige-based leadership may provide a foundation for cooperation in many contexts. Here, inspired by such ethnographic observations and building on a foundation of existing research on the evolution of prestige, we develop a set of formal models to explore when an evolved prestige psychology might drive the cultural evolution ofn-person cooperation, and how such a cultural evolutionary process might create novel selection pressures for genes that make prestigious individuals more prosocial. Our results reveal (i) how prestige can foster the cultural emergence of cooperation by generating correlated behavioural phenotypes, both between leaders and followers, and among followers; (ii) why, in the wake of cultural evolution, natural selection favours genes that make prestigious leaders more prosocial, but only when groups are relatively small; and (iii), why the effectiveness of status differences in generating cooperation in large groups depends on cultural transmission (and not primarily on deference or coercion). Our theoretical framework, and the specific predictions made by these models, sketch out an interdisciplinary research programme that cross-cuts anthropology, biology, psychology and economics. Some of our predictions find support from laboratory work in behavioural economics and are consistent with several real-world patterns.
Supervisory support and organizational citizenship behavior
Authors: Yadav Mohit , Rangnekar Santosh
Published: October 2015

Purpose

– The purpose of this paper is to investigate the role of participation in decision making (PDM) and job satisfaction (JS) in supervisory support and the organizational citizenship behavior (OCB) relationship.

Design/methodology/approach

– Two models with PDM and JS as mediators were tested on the supervisory support-OCB relationship. A sample of 198 Indian business executives was collected exclusively through management development programs (MDPs). To test the hypotheses in this research, correlation and regression analysis were both used. Furthermore, to test the mediation level, Baron and Kenny’s (1986) method was deployed.

Findings

– All variables in the study were found to be significantly related to each other. Both models were supported by the findings, suggesting that supervisory support promotes both PDM and JS. This, in turn, increases OCB in employees. PDM was found to be the better mediator within the relationship. Implications of these results are also discussed.

Research limitations/implications

– Self-reported responses could give biased results; peers should also have been included in the data gathering. Variables in the study cannot be analyzed in isolation. Hence control variables need to be included to arrive at more accurate and informative results.

Practical implications

– The findings contribute to better understanding of the supervisory support/OCB relationship, and the ways of improving this through PDM and JS. As an outcome of this research, organizations should aim to support, empower and involve their employees. Satisfying their needs will lead to them becoming more effective citizens within the organization. Businesses can harness the potential of OCB in employees by giving them a “voice” in decision making and by encouraging them to share ideas.

Originality/value

– The use of PDM and JS in this relationship is unprecedented. The establishment of PDM as a better mediator of the relationship is also unique. The study draws its strength from a multi-organizational sample and the use of MDPs to provide unbiased responses. Since the study is based on an Indian sample, it also adds to the growing literature of OCB from non-western economies.
China’s shadow banking sector: beneficial or harmful to economic growth?
Authors: Barth James R. , Li Tong , Shi Wen , Xu Pei
Published: October 2015

Purpose

– The purpose of this paper is to examine recent developments pertaining to China’s shadow banking sector. Shadow banking has the potential not only to be a beneficial contributor to continued economic growth, but also to contribute to systematic instability if not properly monitored and regulated. An assessment is made in this paper as to whether shadow banking is beneficial or harmful to China’s economic growth.

Design/methodology/approach

– The authors start with providing an overview of shadow banking from a global perspective, with information on its recent growth and importance in selected countries. The authors then focus directly on China’s shadow banking sector, with information on the various entities and activities that comprise the sector. Specifically, the authors examine the interconnections between shadow banking and regular banking in China and the growth in shadow banking to overall economic growth, the growth in the money supply and the growth in commercial bank assets.

Findings

– Despite the wide range in the estimates, the trend in the size of shadow banking in China has been upward over the examined period. There are significant interconnections between the shadow banking sector and the commercial banking sector. Low deposit rate and high reserve requirement ratios have been the major factors driving its growth. Shadow banking has been a contributor, along with money growth, to economic growth.

Practical implications

– The authors argue that shadow banking may prove useful by diversifying China’s financial sector and providing greater investments and savings opportunities to consumers and businesses throughout the country, if the risks of shadow banking are adequately monitored and controlled.

Originality/value

– To the authors’ knowledge, this paper is among the few to systematically evaluate the influence of shadow banking on China’s economic growth.
“I’m going to prove you wrong”
Authors: Vega Desireé , Moore III James L. , Miranda Antoinette H.
Published: October 2015

Purpose

– This study aims to explore perceptions of discrimination among ten African American youths as part of a larger qualitative investigation.

Design/methodology/approach

– The qualitative methodology utilized the “Prove them Wrong Syndrome” as a theoretical framework. Individual interviews and biographical questionnaires were the primary sources of data collection.

Findings

– Four major themes emerged from data analysis: perceived discrimination from others, perceived discrimination from members of one’s own racial group, responses to perceived discrimination and buffers against perceived discrimination.

Practical implications

– Implications for educators including teachers, school psychologists and school counselors are discussed.

Originality/value

– This paper attempted to fill the void in the literature, as it explored the perceptions of discrimination among African American youth, their responses to perceived discrimination and the identification of buffers to compensate for negative experiences with discrimination. Prove them Wrong Syndrome emerged as a major finding in this study as a response to perceived discrimination; nonetheless, it should be further evaluated, as limited research has been conducted in this area. Teachers must be aware of issues students of color may experience at school such as discrimination and how this can harm them emotionally and academically. Moreover, school psychologists and school counselors should be utilized as mental health service providers to combat the potentially negative outcomes of discrimination.
Looking back
Authors: Hardy III Jay H. , Gibson Carter , Buckley M. Ronald
Published: October 2015

Purpose

– The purpose of this paper is to reflect on the early direction and maturation of the Journal of Management History (JOMH), evaluate the lasting impact of this primary work and identify implications of findings of this paper for future developments in the study of management history. This article provides a review of the first five years (1995-1999) of the JOMH.

Design/methodology/approach

– Articles published in the JOMH between the years of 1995 and 1999 were reviewed, and unifying thematic categories were developed. Two independent raters, then, sorted the articles into their respective categories. After agreement was established, general trends in the JOMH’s early direction and focus were considered. Lasting impact was evaluated using citations in Google Scholar by category and year. Similarities among the most cited articles during this period are discussed.

Findings

– The early years of the JOMH were characterized by shifts in contributions from various management and public administration perspectives, a transition from an early emphasis on historical individuals to a broader focus on topics and ideas and a balance between describing historical accounts (i.e. retelling or recording historical events and individuals) and historical analysis (i.e. considering the influence of historical events and ideas on future events and modern perspectives). The most influential early contributions to the JOMH were articles that focused on the histories of specific management concepts, an approach that is still important and relevant today.

Originality/value

– This review provides insights into the development and maturation of the JOMH following its formation.
A review of management history from 2010-2014 utilizing a thematic analysis approach
Authors: Schwarz Colleen
Published: October 2015

Purpose

– The purpose of this paper is to provide a review of the Management History literature in theJournal of Management Historyfrom 2010 to 2014.

Design/methodology/approach

– This review utilized a thematic analysis approach.

Findings

– The author found seven distinct themes in the literature in addition to four subthemes. The themes include management pioneers, crisis management, the dark side of management (including the subthemes of slavery, child labor, monetary factors and gender issues), ancient texts, regional differences, religion and historical impacts of key management concepts.

Practical implications

– This review displays management history research themes, which enables a manager to efficiently view various lenses with which to analyze management issues.

Originality/value

– By bringing together previously disparate streams of work to understand the themes of management history, this paper analyzes the direction of research, identifies gaps in the literature and begins to more effectively build a cumulative research tradition.
The role of institutional repositories in developing the communication of scholarly research
Authors: Marsh Rebecca Mary
Published: October 2015

Purpose

– This paper aims to uncover the central purposes of institutional repositories, how developments are being affected by policies and researcher behaviour and also what services and approaches are appropriate in supporting repositories from those partners involved in scholarly communication with a particular focus on services that support the publication of research.

Design/methodology/approach

– The research reviews the literature and current practices within higher education with regard to the core purposes of institutional repositories, the possible causes of low population of repositories in some institutions and subject disciplines, how this is being addressed and likely future developments. A qualitative survey using semi-structured interviews explores current best practices and tests the specific research questions that emerged from the literature review.

Findings

– The rate at which institutional repositories have grown in number has been very fast in recent years, but the population of repositories with research has been relatively slow. The research identified a number of reasons as to why the population of repositories was likely to accelerate in the future and have a more significant impact on scholarly communication. The main catalysts are: strengthening of national and funder policies that serve to both mandate open access (green or gold) and raise awareness of open access amongst faculty; the alignment of repositories with current research information systems within universities; and the development of metadata and open archives initiative harvesting that will improve discoverability and usage data.

Research limitations/implications

– As many of the issues around the development of repositories centre on the attitudes of faculty, it would also provide an interesting extension to the research to understand their views of the role of institutional repositories, too.

Practical implications

– The study presents a number of possible new ways of working by both information professionals and publishers to improve scholarly communication through the inclusion of research within institutional repositories and how perceived barriers could be overcome.

Social implications

– The study provides guidance on how the communication of scholarly research could be improved and reach a wider audience. This, in turn, will benefit researchers, corporate organisations and the public at large.

Originality/value

– The paper provides a review of current best practices in managing institutional repositories and identifies new ways of addressing some of the perceived barriers to populating repositories and the benefits for each stakeholder in the scholarly communication process.
Facebook use by the open access repository users
Authors: Kurian Jayan Chirayath
Published: October 2015

Purpose

– The purpose of this paper is to explore the type and implications of user-generated content posted by users of an open access institutional repository (DSpace) on Facebook.

Design/methodology/approach

– The identified user-generated content was organised into three categories: personal; professional; and social information. It encompassed all content from the members of the “DSpace” Facebook group, posted during the seven-year period (2007-2014). The posts were read and analysed to identify and categorise user-generated content posted by users to determine how Facebook is used by open access repository users.

Findings

– The results of analysis demonstrate the importance of social information posted by users over personal and professional information. Major types of user-generated content posted by users in the social information category were request, greetings, status-update, and announcement. Further, there has been a threefold increase in the number of user postings in the last two years (2013-2014), when posts were analysed over a seven-year period.

Research limitations/implications

– This study contributes to the theory on the implications eventuating from user-generated content posted by users of an open access institutional repository. An analysis of user-generated content identified in this study implies that users of DSpace open access repository are primarily using Facebook for information seeking, relationship building, and knowledge dissemination.

Practical implications

– By analysing the findings, administrators and policy makers of open access repositories could identify the extent of user support in the form of technical assistance, improved sustainability of supported projects, user community development, marketing and communications required to sustain open access scholarly communication.

Originality/value

– Previous studies examined how social networking sites have been used for a different purpose (interaction, collaboration, and discussion), but to date there has been very little research into the use of Facebook, a public social networking site, by open access repository users. Hence, this study addresses this gap in the literature by an interpretive analysis of user-generated content posted by users on the “DSpace” Facebook group.
Evolution of the online information industry in Spain, 1973-2014
Authors: Muñoz-Cañavate Antonio , Hípola Pedro
Published: October 2015

Purpose

– The purpose of this paper is to first, describe the origins and evolution of electronic information products and services for the business community in Spain and second, to analyze the current distribution of today’s market players.

Design/methodology/approach

– This study is based on a review of the scholarly literature about the information industry, on Spanish annuals and directories about databases, on related legislation, and on the broad experience of the authors who have worked in this field since the 1980s.

Findings

– The early days of the business information industry in Spain developed precariously, in comparison to other parts of the world. Furthermore, the supply of information was almost entirely monopolized by the public administration. Nevertheless, the structure and market players have been completely reorganized, starting in the 1980s, leading to today’s totally transformed panorama.

Originality/value

– Three main factors can explain this evolution: first, growth in the creation of new companies; second, processes of mergers and acquisitions; third, recent consolidation of a group of companies that re-use information generated by the public sector. Their activities have been stimulated by legislative initiatives over the past eight years that promote and regulate this market.
A hybrid indicator for journal ranking
Authors: Hsu Wen-Chin , Tsai Chih-Fong , Li Jia-Huan
Published: October 2015

Purpose

– Although journal rankings are important for authors, readers, publishers, promotion, and tenure committees, it has been argued that the use of different measures (e.g. the journal impact factor (JIF), and Hirsch’s h-index) often lead to different journal rankings, which render it difficult to make an appropriate decision. A hybrid ranking method based on the Borda count approach, the Standardized Average Index (SA index), was introduced to solve this problem. The paper aims to discuss these issues.

Design/methodology/approach

– Citations received by the articles published in 85 Health Care Sciences and Services (HCSS) journals in the period of 2009-2013 were analyzed with the use of the JIF, the h-index, and the SA index.

Findings

– The SA index exhibits a high correlation with the JIF and the h-index (γ
>
0.9, p
<
0.01) and yields results with higher accuracy than the h-index. The new, comprehensive citation impact analysis of the 85 HCSS journals shows that the SA index can help researchers to find journals with both high JIFs and high h-indices more easily, thereby harvesting references for paper submissions and research directions.

Originality/value

– The contribution of this study is the application of the Borda count approach to combine the HCSS journal rankings produced by the two widely accepted indices of the JIF and the h-index. The new HCSS journal rankings can be used by publishers, journal editors, researchers, policymakers, librarians, and practitioners as a reference for journal selection and the establishment of decisions and professional judgment.

Paraneoplastic pemphigus (PNP) is an autoimmune blistering disease that presents as severe mucosal erosions and variable cutaneous lesions and is primarily associated with hematologically malignant or benign diseases. A 59‐year‐old Japanese woman presented with oral, ocular and vaginal mucosal erosions and erythema as well as blistering on her trunk and limbs. She developed bronchiolitis obliterans; lymphadenopathy in the cervical, subclavian, para‐aortic and intraperitoneal regions; and splenomegaly. PNP with B‐cell lymphoma was diagnosed. She was treated with two courses of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R‐CHOP) for B‐cell lymphoma, rituximab once every 3 weeks for five cycles, steroid pulse therapy, oral prednisolone, cyclosporin and high‐dose i.v. immunoglobulin. The B‐cell lymphoma was in remission after two courses of R‐CHOP treatment. Although her skin erythema and blistering were also improved, the mucosal erosions and bronchiolitis obliterans gradually worsened. The patient died of bronchiolitis obliterans after 6 months of hospitalization. Because a cellular immune response is thought to be involved in the pathogenesis of PNP, cyclosporin therapy is expected to aid in suppressing the cellular response. In this case, however, the patient's mucosal lesions and bronchiolitis obliterans were not improved by regular administration of cyclosporin therapy.

Preceding this study, we observed two cases of concurrent postoperative gluteal skin and muscle damage with extremely high serum creatine kinase (CK) levels, both of which were unrelated to pressure‐induced tissue injury. However, postoperative gluteal skin damage accompanied by gluteal muscle damage has not been previously reported and the association between gluteal skin damage, gluteal muscle damage and pressure‐induced tissue injury has not previously been investigated. Therefore, we conducted this study to determine the postoperative incidence of gluteal skin damage associated with gluteal muscle damage and assess associations with postoperative serum CK levels and pressure‐induced tissue injury. We prospectively evaluated postoperative incidence of gluteal skin damage and measured serum CK levels in 929 consecutive patients who underwent abdominal, urological or gynecological surgery at our hospital. Magnetic resonance imaging (MRI) of the pelvis was performed in 67 patients who consented. As a result, two of 929 patients developed postoperative gluteal skin damage accompanied by gluteal muscle damage. Gluteal muscle damage without gluteal skin damage was observed in 23 of the 67 patients who underwent MRI, and volumes of damaged gluteal muscle and postoperative serum CK levels were positively correlated. Both gluteal skin and muscle damage were distinguishable from pressure‐induced tissue injury. Based on the results of this study, we could confirm the occurrence of postoperative gluteal skin damage, distinct from pressure sores, accompanied by gluteal muscle damage. We also revealed latent development of postoperative gluteal muscle damage, distinguishable from compression‐induced tissue injury, without accompanying gluteal skin damage.
Quantifying risk and resource use for a large carnivore in an expanding urban–wildland interface

Large carnivores, though globally threatened, are increasingly using developed landscapes. However, most of our knowledge of their ecology is derived from studies in wildland systems; thus, for effective conservation and management, there is a need to understand their behavioural plasticity and risk of mortality in more developed landscapes.

We examined cougarPuma concolorforaging ecology and survival in an expanding urban–wildland system in Colorado from 2007 to 2013. ForGPS‐collared individuals, we related diet (n = 41; isotopic analysis) to age–sex class and fine‐scale space use, with regard to levels of habitat development. We also examined how habitat development impacted risk of mortality (n = 49), using hazards models and records of cougar–human conflict.

Cougars obtained 63–82% of assimilated biomass from native herbivores, and adult females consistently showed higher use of native herbivores than other age–sex classes. Individuals using the most highly developed areas obtained approximately 20% more of their diet from alternative prey (synanthropic wildlife and domestic species) than those in the least developed areas.

Overall, survival of adult females was higher than adult males. Yet, use of developed areas substantially increased cougar risk of mortality; for every 10% increase in housing density, risk of mortality increased by 6·5%, regardless of sex.

Synthesis and applications. Cougars showed flexibility in diet, taking advantage of human‐associated prey items, but had high rates of mortality, suggesting that human tolerance, rather than adaptability, may be the limiting factor for range expansion by cougar and other large carnivores. Thus, large carnivore conservation will not only depend upon adequate prey resources, but also limiting potential conflict resulting from depredation of synanthropic wildlife and domestic animals.
