Authors: GESY K. , HILL J. E. , SCHWANTJE H. , LICCIOLI S. , JENKINS E. J. 
Published: May 2013

SUMMARYIn 2009, a haplotype closely related to European strains of Echinococcus multilocularis was detected in a dog from the Quesnel region of British Columbia, Canada. We now report the establishment of this same haplotype in 7 coyotes (Canis latrans) trapped within 40 km of Quesnel, BC. In addition, 3 coyotes and 1 red fox (Vulpes vulpes) harboured adult cestodes morphologically compatible with that of E. multilocularis (overall prevalence 33% in 33 carnivores). None of 156 potential intermediate hosts, including 131 representatives of two highly suitable rodent species, Peromyscus maniculatus and Microtus pennsylvanicus, trapped from a region 120–210 km south of Quesnel were infected. This report confirms the establishment and local transmission of a European-type strain of E. multilocularis (the causative agent of human alveolar hydatid disease), in wildlife in a forested region of North America where this cestode had not been previously detected, with significance for public and animal health.
Population structure and canopy use by Coussapoa microcarpa, a strangler hemiepiphyte from the Brazilian Atlantic Forest
Authors: Coelho Luís Francisco Mello , Pizo Marco Aurélio 
Published: May 2013

Abstract:We studied density, size structure, and establishment sites of Coussapoa microcarpa in the Brazilian Atlantic rain forest. This species is a hemiepiphyte that begins its life in the tops of trees and survives the death of its host to become a free-standing tree. All individuals of C. microcarpa already rooted in the ground were recorded in a 3.43 ha (1.75 ha in lowland and 1.68 ha in submontane) sample of forest plots. Data on total height, root diameter at breast height, host height and diameter at breast height, as well as height, type and diameter of the establishment site were collected. Coussapoa microcarpa present a high density (36.5 ind. ha−1) and the population studied was composed mainly of young individuals. Young and adults differed in establishment sites. The diameter of establishment sites of young was narrower than the diameter of establishment sites of adults, which points out to a limiting factor (diameter of establishment site) regulating the establishment of C. microcarpa.
Changes in pollinator assemblages following hurricanes affect the mating system ofLaguncularia racemosa(Combretaceae) in Florida, USA
Authors: Landry Carol L. 
Published: May 2013

Abstract:Hurricanes are major disturbance events in Neotropical mangrove communities, potentially affecting the reproductive success of mangrove species. This was the first investigation of changes in mangrove pollinator assemblages following hurricanes, and the effect of these changes on the mating system ofLaguncularia racemosa. Insect pollinator assemblages were investigated in three Florida mangrove communities in 2001–2003, 2005 and 2009; two hurricanes affected the area in 2004. Visitation rates were estimated from 1445 insects observed during 272 10-min intervals; the number of flowers visited by each insect was also recorded. Pollinator diversity was estimated with the Shannon Index. Following the hurricanes, species richness was reduced by 43–65% and diversity declined by 36–70%. Significant declines in insect visitation toL. racemosaresulted in reduced outcrossing frequencies in 2005.Laguncularia racemosaflowers autogamously self-pollinate without insect visitors, so fruit set still occurred. Visitation rates returned to pre-hurricane levels by 2009, but foraging behaviours differed from pre-hurricane patterns; outcrossing was further favoured by reduced frequencies of long foraging bouts and increased frequencies of short foraging bouts. The mixed mating system ofL. racemosaprovides reproductive assurance following hurricane disturbances, when pollinator abundance is low.
The communicative contexts of grammatical aspect use in English
Authors: IBBOTSON PAUL , LIEVEN ELENA , TOMASELLO MICHAEL 
Published: May 2013

ABSTRACTIn many of the world's languages grammatical aspect is used to indicate how events unfold over time. In English, activities that are ongoing can be distinguished from those that are completed using the morphological marker -ing. Using naturalistic observations of two children in their third year of life, we quantify the availability and reliability of the imperfective form in the communicative context of the child performing actions. On average, 30% of verbal descriptions refer to child actions that are grounded in the here-and-now. Of these utterances, there are two features of the communicative context that reliably map onto the functions of the imperfective, namely, that events are construed as ongoing and from within. The findings are discussed with reference to how the context in which a child hears aspectual language may limit the degrees of freedom on what these constructions mean.
Participation in Policy Discourse: New Form of Exclusion for Seniors with Disabilities?
Authors: Raymond Émilie , Grenier Amanda 
Published: May 2013

RÉSUMÉLes récents discours sur le vieillissement donnent beaucoup d’importance au thème de la participation sociale des aînés. Cependant, la manière dont la participation est définie dans les politiques et les pratiques sociales ne correspond pas nécessairement aux réalités de tous les aînés. Cet article présente les conclusions d’une analyse critique de discours qui a examiné des politiques sur le vieillissement développées par la province de Québec, au Canada, entre 2005 et 2011. Les résultats montrent que les interprétations émergentes de la participation peuvent être problématiques lorsqu’elles sont associées à des recommandations, des standards et des attentes. Premièrement, les documents analysés montrent que la participation est de plus en plus définie en termes de productivité et que la notion de bien-être des aînés a été remplacée par celle d’utilité. Deuxièmement, le contexte de la participation est passé d’une responsabilité collective à une question de choix personnel et d’ajustement des [aux] communautés locales. Troisièmement, les documents reflètent une polarisation de l’activité et de la perte d’autonomie qui a pour conséquence d’associer participation et bonne santé. Ces résultats suggèrent que bien qu’innovante dans le cadre canadien, l’articulation de la participation telle que proposée dans les politiques québécoises sur le vieillissement est dépourvue des éléments politiques nécessaires à l’inclusion et à la discussion de la différence, de l’altérité et de l’accès aux espaces participatifs. Le cas des personnes vieillissant avec une incapacité physique illustre les défis inhérents à ce nouvel agenda participatif.
Effect of Dy-doping on the microstructure and magnetic properties of Y1−xDyxMnO3

Published: May 2013

The effect of Dy3+ doping at A-site in hexagonal YMnO3 on the microstructure and magnetic properties was studied. Polycrystalline Y1−xDyxMnO3 samples with x ranging from 0 to 1 were synthesized by the solid-state reaction method. The microstructures of all the samples were studied by X-ray diffraction, which shows that Y1−xDyxMnO3 with a low concentration (x ≤ 0.5) of Dy3+ retains a hexagonal symmetry. The crystal structure refinements of the hexagonal Y1−xDyxMnO3 using the Rietveld method show that the unit-cell parameters of a, c, and unit-cell volume increase with increasing Dy doping, while the MnO5 trigonal bipyramids remain almost unchanged. The remarkable increasing of magnetic moment at a low temperature with increasing the Dy3+ doping concentration is ascribed to the spin order of Dy3+ and the increasing Dy3+–Mn3+ coupling and Mn3+–O–O–Mn3+ interaction.
The occurrence of melioidosis is related to different climatic conditions in distinct topographical areas of Taiwan

Published: May 2013

SUMMARYThis study assessed the correlations between the incidence of melioidosis and rainfall, wind strength and wind direction in both the flat and hilly regions of Taiwan. Data from the melioidosis and climate databases from 2005 to 2011 were combined and analysed. With the inclusion of a lag time accounting for a possible incubation period for melioidosis, the daily rainfall and wind-speed data were correlated with the number of confirmed melioidosis cases. The incidence of melioidosis in the flat region was related to the wind speed (>19 m/s) and the specific angle (150°, 220°, 280°) of the wind direction. Rainfall is a common environmental factor that contributes to an increase in the incidence of melioidosis in both areas; however, the contribution of wind strength or wind direction to the spread of melioidosis was restricted to areas with specific topographical characteristics, such as hills.
Climate policy and equity principles: fair burden sharing in a dynamic world
Authors: Bretschger Lucas 
Published: May 2013

AbstractThe paper argues that negotiation costs can prevent the international community from finding a new international climate agreement. To define a feasible way of facilitating the negotiation process, I analyze basic equity principles and their relationship to climate policy and economic development. Based on the most relevant principles, I propose a general synthetic rule for burden sharing in international climate policy. The rule avoids complexity and comprises both egalitarian and cost-sharing aspects, which appears to be crucial for achieving a climate agreement. Carbon budgets for the different countries are calculated under different parameter assumptions.
Strategic delaying and concessions extraction in accession negotiations to the World Trade Organization: an analysis of Working Party membership
Authors: NEUMAYER ERIC 
Published: May 2013

AbstractAccession to the World Trade Organization (WTO) is unlike accession to other global organizations. It is extremely demanding on applicant countries, time consuming and essentially power- rather than rule-based. This article argues that existing WTO members select themselves into the Working Party of applicant countries, the body which determines the timing and conditions of accession, in order to have the option to strategically delay membership by the applicant and/or extract concessions from it. Existing members will select themselves into a specific Working Party if their own trade interests are strongly affected, which will be the case if the existing member's bilateral trade with the applicant country forms a large share of its income, unless both countries already have a preferential trade agreement (PTA) between them. Trade interests are also strongly affected if the existing member competes with the applicant in terms of export product and market structure. Conversely, where both member and applicant have more PTAs with third countries of large economic size in common, potential accession will affect the member's trade interests less. An empirical analysis of Working Party membership since 1968 estimates to what extent these three different facets of trade interests are substantively important determinants of Working Party composition.
Innate pro–B-cell progenitors protect against type 1 diabetes by regulating autoimmune effector T cells

Published: May 2013

Significance
Immunoregulatory poperties have been principally ascribed to various mature immune cell types, including regulatory B cells. An immature B-cell progenitor population endowed with suppressive properties per se or after differentiation into more mature regulatory B cells has not been demonstrated as yet. We now describe a pro–B-cell progenitor population that emerged upon stimulation with the Toll-like receptor-9 ligand CpG and prevented disease upon adoptive transfer into autoimmune type 1 diabetes-prone mice. Effector T cells were the target of immunoregulatory pro-B cells and of their mature progeny. Such protective pro-B cells could be instrumental for cell therapy of autoimmune diseases.
HitPick: a web server for hit identification and target prediction of chemical screenings
Authors: Liu Xueping , Vogt Ingo , Haque Tanzeem , Campillos Mónica 
Published: May 2013

Abstract
Motivation: High-throughput phenotypic assays reveal information about the molecules that modulate biological processes, such as a disease phenotype and a signaling pathway. In these assays, the identification of hits along with their molecular targets is critical to understand the chemical activities modulating the biological system. Here, we present HitPick, a web server for identification of hits in high-throughput chemical screenings and prediction of their molecular targets. HitPick applies the B-score method for hit identification and a newly developed approach combining 1-nearest-neighbor (1NN) similarity searching and Laplacian-modified naïve Bayesian target models to predict targets of identified hits. The performance of the HitPick web server is presented and discussed.

EpiCombFlu: exploring known influenza epitopes and their combination to design a universal influenza vaccine
Authors: Jaiswal Varun , Chanumolu Sree K. , Sharma Pankaj , Chauhan Rajinder S. , Rout Chittaranjan 
Published: May 2013

Abstract
Motivation: Influenza is responsible for half a million deaths annually, and vaccination is the best preventive measure against this pervasive health problem. Influenza vaccines developed from surveillance data of each season are strain-specific, and therefore, are unable to provide protection against pandemic strains arising from antigenic shift and drift. Seasonal epidemics and occasional pandemics of influenza have created a need for a universal influenza vaccine (UIV). Researchers have shown that a combination of conserved epitopes has the potential to be used as a UIV.
Result: In the present work, available data on strains, proteins, epitopes and their associated information were used to develop a Web resource, ‘EpiCombFlu’, which can explore different influenza epitopes and their combinations for conservation among different strains, population coverage and immune response for vaccine design. Forward selection algorithm was implemented in EpiCombFlu to select optimum combination of epitopes that may be expressed and evaluated as potential UIV.

First Report of “Candidatus Liberibacter solanacearum” on Tomato in Honduras
Authors: Aguilar E. , Sengoda V. G. , Bextine B. , McCue K. F. , Munyaneza J. E. 
Published: May 2013

Tomato (Lycopersicum esculentum) crops grown in several departments of Honduras and heavily infested with the psyllid Bactericera cockerelli were observed in April of 2012 with plant symptoms suggestive of “Candidatus Liberibacter solanacearum” infection. B. cockerelli is a serious pest of potato, tomato, and other solanaceous plants and a vector of “Ca. L. solanacearum” (1,2,3,4). The symptoms included overall chlorosis, severe stunting, leaf cupping, excessive branching of axillary shoots, and leaf purpling and scorching (2,3). Disease incidence ranged from 5 to 50% symptomatic plants per field. Tomato (cv. Pony) plant samples were collected from two psyllid-infested commercial fields in the municipalities of Danli and Comayagua in the departments of El-Paraiso and Comayagua, respectively. Total DNA was extracted from leaf tissues of 50 and 20 symptomatic and asymptomatic plants, respectively, with the cetyltrimethylammonium bromide (CTAB) buffer extraction method (1,3). The DNA samples were tested for “Ca. L. solanacearum” by PCR with primer pairs specific for 16S rDNA (OA2 and OI2c) and the outer membrane protein gene (OMB 1482f and 2086r) of the bacterium (1,2). Ten (20%) of the 50 symptomatic tomato samples were positive for “Ca. L. solanacearum” using both primer pairs and the remaining samples were negative for the bacterium with both primer sets. None of the 20 asymptomatic plants tested positive for “Ca. L. solanacearum”. Amplicons from DNA of two plant samples (one plant/municipality) with each primer pair were cloned and four clones of each of the four amplicons were sequenced. BLASTn analysis of the 16S rDNA consensus sequences from the clones (deposited in GenBank as Accession Nos. KC768321 and KC768322) were identical for both locations and showed 99 to 100% identity to several “Ca. L. solanacearum” sequences in GenBank (e.g., JN848753, JN84856, and HM246509). The OMB consensus sequences from the two tomato plants (deposited in GenBank as KC768329 and KC768330) were 100% identical to OMB sequences of Lso in GenBank (CP002371 and JN48754, respectively). To our knowledge, this is the first report of “Ca. Liberibacter solanacearum” associated with tomato crops in Honduras. This bacterium has caused millions of dollars in losses to the tomato industry in the United States, Mexico, and New Zealand (2,3,4). Serious damages to tomato crops due to “Ca. L. solanacearum” could expand throughout Central America, especially in those countries where B. cockerelli occurs. References: (1) J. M. Crosslin. Southwest. Entomol. 36:125, 2011. (2) L. W.

AbstractPlasticity of root growth in response to environmental cues and stresses is a fundamental characteristic of land plants. However, the molecular basis underlying the regulation of root growth under stressful conditions is poorly understood. Here, we report that a rice nuclear factor, RICE SALT SENSITIVE3 (RSS3), regulates root cell elongation during adaptation to salinity. Loss of function of RSS3 only moderately inhibits cell elongation under normal conditions, but it provokes spontaneous root cell swelling, accompanied by severe root growth inhibition, under saline conditions. RSS3 is preferentially expressed in the root tip and forms a ternary complex with class-C basic helix-loop-helix (bHLH) transcription factors and JASMONATE ZIM-DOMAIN proteins, the latter of which are the key regulators of jasmonate (JA) signaling. The mutated protein arising from the rss3 allele fails to interact with bHLH factors, and the expression of a significant portion of JA-responsive genes is upregulated in rss3. These results, together with the known roles of JAs in root growth regulation, suggest that RSS3 modulates the expression of JA-responsive genes and plays a crucial role in a mechanism that sustains root cell elongation at appropriate rates under stressful conditions.
The review of approaches to knowledge management system studies
Authors: Matayong Sureena , Kamil Mahmood Ahmad 
Published: May 2013

PurposeThis paper reviews the current literature of knowledge management systems (KMS) studies in organizations. The authors systematically review the literature according to the principle of innovation studies approach, i.e. variance and process approaches. The purpose of this paper is to identify the current state of KMS studies in organizations. By doing this, the way is paved for the authors to find the research gaps, which would facilatively suggest the direction for future research. The authors hope that this review will be regarded as a source for those who share mutual interests in KMS research and could stimulate further research being conducted in the area with different approaches in the future.Design/methodology/approachJournal articles published within the period 2003‐2013 were collected. The articles were sourced mainly from Emerald, Science Direct, IEEE,MIS Quarterly, as well as some other academic databases. The search was conducted using such keywords as “knowledge management system” “knowledge repository” “knowledge management tools” “system for knowledge management” and “knowledge‐based system”.FindingsIt was found that the majority of KMS studies primarily pertain to adoption, diffusion, usage, and implementation, which are fundamentally based on a variance approach. The studies based on a process approach, however, are found to be scarce and still lacking. The authors highlight the findings and provide a critical review of the current approach, as well as commenting on the traditional theories that have been applied, unified, and modified for the studies of KMS in organizations. The authors also suggest some appropriate approaches to studying KMS in organizations and future directions for further research in this field.Research limitations/implicationsThe paper has produced a certain result of review studies from the existing literature during the period 2003‐2013. However, the review mainly focused on different approaches that looked into the classification of study schemes and theories being applied for research, while not focusing on other aspects that may be relevant to the area of studies.Originality/valueThe result of this review highlights some gaps in the literature in terms of findings and critical observation of the theoretical and methodological approaches to the research of KMS studies in organizations. Directions for future research are suggested.
Determinants of knowledge sharing in a public sector organization
Authors: Titi Amayah Angela 
Published: May 2013

PurposeThe purpose of this paper is to investigate the factors that affect knowledge sharing in a public sector organization.Design/methodology/approachThe paper is based on quantitative research. The data were gathered through questionnaires and analyzed using multiple regression.FindingsCommunity‐related considerations, normative considerations and personal benefits were three motivators found to have a unique contribution to the variance in knowledge sharing. The following enablers had a significant main effect on knowledge sharing: social interaction, rewards, and organizational support. Two barriers, degree of courage and degree of empathy, which measured organizational climate, were found to have a significant main effect on knowledge sharing. The interaction of normative consideration with social interaction, personal benefit with organizational support, and normative considerations with degree of courage, had a moderating effect on the relationship between motivating factors and knowledge sharing.Research limitations/implicationsThe study was conducted in a single public sector organization, which limits the generalizability of the findings to other settings. Another limitation is that attitudes toward knowledge sharing, and knowledge‐sharing behaviors, vary across cultures. Finally, self‐reported data are subject to response bias.Practical implicationsIdentifying factors that influence knowledge sharing could help practitioners create a knowledge‐sharing culture that is needed to support knowledge sharing and knowledge management within public sector organizations.Originality/valueThis empirical study will contribute to the theoretical knowledge on knowledge sharing in the public sector, which has been neglected in knowledge‐sharing research.
