Does Bold Emphasis Facilitate the Process of Visual-Word Recognition?
Authors: Macaya María , Perea Manuel 
Published: February 2014

AbstractThe study of the effects of typographical factors on lexical access has been rather neglected in the literature on visual-word recognition. Indeed, current computational models of visual-word recognition employ an unrefined letter feature level in their coding schemes. In a letter recognition experiment, Pelli, Burns, Farell, and Moore-Page (2006), letters in Bookman boldface produced more efficiency (i.e., a higher ratio of thresholds of an ideal observer versus a human observer) than the letters in Bookman regular under visual noise. Here we examined whether the effect of bold emphasis can be generalized to a common visual-word recognition task (lexical decision: “is the item a word?”) under standard viewing conditions. Each stimulus was presented either with or without bold emphasis (e.g., actor vs. actor). To help determine the locus of the effect of bold emphasis, word-frequency (low vs. high) was also manipulated. Results revealed that responses to words in boldface were faster than the responses to the words without emphasis –this advantage was restricted to low-frequency words. Thus, typographical features play a non-negligible role during visual-word recognition and, hence, the letter feature level of current models of visual-word recognition should be amended.
Psychological Inflexibility Mediates the Effects of Self-Efficacy and Anxiety Sensitivity on Worry
Authors: Ruiz Francisco J. 
Published: February 2014

AbstractRecent research has found low levels of general self-efficacy (GSE: beliefs about the ability to appropriately handle a wide range of stressors) and high levels of anxiety sensitivity (AS: fear of the negative consequences of experiencing anxiety) to be relevant predictors of pathological worry. This study examined the role of psychological inflexibility (PI: the dominance of private experiences over chosen values and contingencies in guiding action), the central component of the acceptance and commitment therapy model of psychopathology, in the effect of GSE and AS on worry. A total of 132 nonclinical participants completed questionnaires assessing the constructs of interest. Partial correlations and regression analyses showed that both GSE and AS were independent predictors of pathological worry after controlling for each other. However, mediation analyses revealed that psychological inflexibility completely mediated the independent effects of both GSE and AS on pathological worry. Theoretical and treatment implications of the results are discussed.
Service Climate as a Mediator of Organizational Empowerment in Customer-Service Employees
Authors: Mendoza-Sierra Maria Isabel , Orgambídez-Ramos Alejandro , Carrasco-González Ana María , León-Jariego José Carlos 
Published: February 2014

AbstractThe aim of this study is to examine the mediating role of the service climate between organizational empowerment (i.e., dynamic structural framework, control of workplace decisions, fluidity in information sharing) and service quality (functional and relational). 428 contact employees from 46 hotels participated in the survey. Correlations demonstrated that dynamic structural framework, control decisions, and fluidity in information sharing are related to both functional and relational service quality. Regression analyses and Sobel tests revealed that service climate totally mediated the relationship between all three dimensions of organizational empowerment and relational service quality. Implications for practice and future research are discussed.
Beliefs about Children’s Adjustment in Same-Sex Families: Spanish and Chilean University Students
Authors: Frias-Navarro Dolores , Monterde-i-Bort Hector , Barrientos-Delgado Jaime , Badenes-Ribera Laura , Cardenas-Castro Manuel 
Published: February 2014

AbstractThe main purpose of our study is to compare the beliefs of Spanish and Chilean university students about the effects that same-sex parents might have on their children. A total of 491 participants completed the study (208 Spaniards and 283 Chileans). The results indicate a kind of modern and subtle rejection based on hetero-normativity. Furthermore, the results indicated the effects of sex (men have a greater degree of rejection), traditional and sexist opinions linked to a greater rejection of same-sex parents, and the contact variable which inversely correlates with this rejection. The results show that the etiology of homosexual orientation also correlates with rejection of same-sex parents when it is believed that homosexuality is learned or can be changed.
Effect of morphology on electrical treeing in low density polyethylene nanocomposites
Authors: Alapati Sridhar , Meledath Joy Thomas , Karmarkar Ajay 
Published: February 2014

Influence of polymer morphology on the inception and the growth of electrical trees in unfilled low density polyethylene (LDPE) as well as LDPE filled with 1, 3 and 5% by weight nanoalumina samples stressed with 50 Hz ac voltage has been studied. It is seen that there is a significant improvement in tree inception voltage with filler loading in LDPE filled with nanoparticles. Tree inception voltage increased with the filler loading up to 3% by weight nanoalumina loading and showed a reduction at 5% by weight loading. Change in tree growth patterns from branch to bush as well as a slower tree growth with increase in filler loading in LDPE alumina nanocomposites were observed. The degree of crystallinity and change in crystalline morphology induced by the presence of alumina nanoparticles in LDPE was studied using differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). DSC results show a similar melting behaviour for both unfilled LDPE and LDPE nanocomposites. However, there is a reduction in the degree of crystallinity for LDPE filled with 5% by weight nanoalumina. An increase in lamellae packing with increase in filler loadings and a highly disordered spherulitic structure for LDPE filled with 5% by weight nanoalumina was observed from the SEM images. The slow propagation of tree growth as well as reduction in tree inception voltage with increase in filler loadings were attributed to the morphological changes observed in the LDPE nanocomposites.
One-Stage Open Reduction of an Old Cervical Subluxation: Case Report
Authors: Barrenechea Ignacio J. 
Published: February 2014

Study Design Case report. Objective The recommended treatment of cervical subluxation is currently closed or open reduction. These treatments are better accomplished in the acute setting, when muscular and ligamentous laxity allows the required maneuvers to realign the dislocated segments. However, subsets of patients are still being treated subacutely. The majority of the literature addressing subacute subluxations reports treatment through “front and back” approaches, many of them performed in two, three, or even four stages. Other authors recommend days or weeks of traction to reduce the subluxation, followed by anterior or posterior approaches. Herein, we present a one-stage open posterior surgical treatment of a 2-month standing C5–C6 subluxation with “jumped facets,” describing a useful technique to reduce these challenging cases without the need of traction or multistage procedures. Methods After opening and exposing the posterior elements, we performed a wide C5–6 bilateral foraminotomy; we then put lateral mass screws and rods from C4 to C6. Resembling the technique used in the reduction of high-grade lumbar spondylolisthesis, we used a rod reducer to bring back the C5 screw head toward the rod, thus realigning the lateral mass screw heads and reducing the subluxation. Results No changes were observed in the motor evoked or somatosensory potentials during this maneuver. Following an uneventful procedure, the patient was transferred to the postanesthetic care unit and discharged 3 days later. Conclusions This open single-stage posterior approach dramatically reduces operating time. This technique could be added into the decision-making armamentarium for cases without disk herniation.
The dative alternation in South Asian English(es)
Authors: Bernaisch Tobias , Gries Stefan Th. , Mukherjee Joybrato 
Published: February 2014

The present paper focuses on the modelling of cross-varietal differences and similarities in South Asian English(es) and British English at the level of verb complementation. Specifically, we analyse the dative alternation with GIVE, i.e. the alternation between the double-object construction (John gave Mary a book) and the prepositional dative (John gave a book to Mary) as well as their passivised constructions with regard to the factors that potentially exert an influence on this alternation in seven varieties of English. The South Asian varieties under scrutiny are Bangladeshi English, Indian English, Maldivian English, Nepali English, Pakistani English and Sri Lankan English, while British English serves as the reference variety. The patterns of GIVE are annotated according to the following parameters including potential predictors of the dative alternation: syntactic pattern and semantic class of GIVE; syntactic complexity, animacy, discourse accessibility and pronominality of constituents (cf. Gries 2003b; Bresnan and Hay 2008). The choices of complementation patterns are then statistically modelled using conditional inference trees and a random-forest analysis.The results indicate that many of the predictors found to be relevant in British English are at play in the South Asian varieties, too. The syntactic pattern of GIVE is, in descending order, uniformly influenced by the predictors pronominality of recipient, length of recipient, semantic class of GIVE and length of patient. Interestingly, the predictor country is marginal in accounting for the dative alternation of GIVE across the varieties at hand. Based on this observation, we derive variety-independent protostructions, i.e. abstract combinations of (cross-varietally stable) features with high predictive power for a particular syntactic pattern, which we argue to be part of the lexicogrammatical “common core” (Quirket al. 1985: 16) of English.The implications of the present paper are twofold. While the order of the predictors regarding their influence on the dative alternation is clearly compatible with earlier studies (cf. e.g. Green 1974; Ransom 1979; Hawkins 1994; Gries 2003b), the stability of the order across varieties of English calls for a) a more fine-grained gradation of linguistic forms and structures at the lexis-grammar interface as indicators of structural nativisation and b) a revision of earlier verb-complementational findings specific to individual or groups of varieties of South Asian English.
American White Pelican Predation on Cui-ui in Pyramid Lake, Nevada
Authors: Scoppettone G. Gary , Rissler Peter H. , Fabes Mark C. , Withers Donna 
Published: February 2014

Abstract
Anthropogenic changes to the Pyramid Lake–Truckee River ecosystem in Nevada are suspected to have altered the predator–prey balance between American white pelican Pelecanus erythrorhynchos and Cui-ui Chasmistes cujus. We estimated the loss of the adult Cui-ui population to pelican predation over a 13-year period by netting and tagging Cui-uis as they aggregated at the mouth of the Truckee River prior to their spawning migration into the Truckee River. Cui-ui access to the Truckee River typically required traversing a shallow delta (a foraging advantage for these American white pelicans). Dams and greater frequency of low stream flows also contributed to American white pelican foraging success. We used tag recoveries from Pyramid Lake's nesting colony of American white pelicans along with an experiment to estimate the chance of tag recovery within the colony to calculate the number of tagged fish taken by American white pelicans. We also used numbered tags to test whether there was a size preference for Cui-uis taken. Our results showed that the primary source of adult Cui-ui mortality was from American white pelican predation in the Truckee River. Within a 13-year period American white pelicans had taken 90% of the tags deployed during the first 7 years of the interval. There was no preference for the size of Cui-uis taken. A better understanding of the effects of heavy cropping by American white pelicans on Cui-ui population dynamics is still needed.

Mantra 2.0: an online collaborative resource for drug mode of action and repurposing by network analysis
Authors: Carrella Diego , Napolitano Francesco , Rispoli Rossella , Miglietta Mario , Carissimo Annamaria , Cutillo Luisa , Sirci Francesco , Gregoretti Francesco , Di Bernardo Diego 
Published: February 2014

Abstract
Summary: Elucidation of molecular targets of a compound [mode of action (MoA)] and its off-targets is a crucial step in drug development. We developed an online collaborative resource (MANTRA 2.0) that supports this process by exploiting similarities between drug-induced transcriptional profiles. Drugs are organized in a network of nodes (drugs) and edges (similarities) highlighting ‘communities’ of drugs sharing a similar MoA. A user can upload gene expression profiles before and after drug treatment in one or multiple cell types. An automated processing pipeline transforms the gene expression profiles into a unique drug ‘node’ embedded in the drug-network. Visual inspection of the neighbouring drugs and communities helps in revealing its MoA and to suggest new applications of known drugs (drug repurposing). MANTRA 2.0 allows storing and sharing user-generated network nodes, thus making MANTRA 2.0 a collaborative ever-growing resource.

MRHMMs: Multivariate Regression Hidden Markov Models and the variantS
Authors: Lee Yeonok , Ghosh Debashis , Hardison Ross C. , Zhang Yu 
Published: February 2014

Abstract
Summary: Hidden Markov models (HMMs) are flexible and widely used in scientific studies. Particularly in genomics and genetics, there are multiple distinct regimes in the genome within each of which the relationships among multivariate features are distinct. Examples include differential gene regulation depending on gene functions and experimental conditions, and varying combinatorial patterns of multiple transcription factors. We developed a software package called MRHMMs (Multivariate Regression Hidden Markov Models and the variantS) that accommodates a variety of HMMs that can be flexibly applied to many biological studies and beyond. MRHMMs supplements existing HMM software packages in two aspects. First, MRHMMs provides a diverse set of emission probability structures, including mixture of multivariate normal distributions and (logistic) regression models. Second, MRHMMs is computationally efficient for analyzing large data-sets generated in current genome-wide studies. Especially, the software is written in C for the speed advantage and further amenable to implement alternative models to meet users’ own purposes.

An experimentally determined evolutionary model dramatically improves phylogenetic fit
Authors: Bloom Jesse D. 
Published: February 2014

AbstractAll modern approaches to molecular phylogenetics require a quantitative model for how genes evolve. Unfortunately, existing evolutionary models do not realistically represent the site-heterogeneous selection that governs actual sequence change. Attempts to remedy this problem have involved augmenting these models with a burgeoning number of free parameters. Here I demonstrate an alternative: experimental determination of a parameter-free evolutionary model via mutagenesis, functional selection, and deep sequencing. Using this strategy, I create an evolutionary model for influenza nucleoprotein that describes the gene phylogeny far better than existing models with dozens or even hundreds of free parameters. Emerging high-throughput experimental strategies such as the one employed here provide fundamentally new information that has the potential to transform the sensitivity of phylogenetic and genetic analyses.
The cocrystalrac-1-[(N,4-dimethylbenzenesulfonamido)methyl]-2-(diphenylphosphoryl)ferrocene–rac-1-[(N,4-dimethylbenzenesulfonamido)methyl]-2-(diphenylphosphanyl)ferrocene (0.45/0.55)

Published: February 2014

As part of our interest in the synthesis and catalytic applications of chiral (diphenylphosphanyl)ferrocene ligands, we designed a number of P,N-containing ligands for use in asymmetric transfer hydrogenation (ATH). During the synthetic procedure to obtainrac-1-[(N,4-dimethylbenzenesulfonamido)methyl]-2-(diphenylphosphanyl)ferrocene, the title compound, [Fe(C5H5)(C26H25NO2PS)]0.55·[Fe(C5H5)(C26H25NO3PS)]0.45, was obtained as a by-product. It is composed of a ferrocene group disubstituted by a partially oxidized diphenylphosphanyl group, as confirmed by31P NMR analysis, and an (N,4-dimethylbenzenesulfonamido)methyl substituent. Owing to the partially oxidized diphenylphosphanyl group, it is best to view the crystal as being composed of a mixture of non-oxidized and oxidized phosphane, so it can be regarded as a cocrystal. It is also a racemate. To the best of our knowledge, the P=O distance [1.344 (4) Å] is the shortest observed for related (diphenylphosphoryl)ferrocene compounds. The packing is stabilized by weak C—H...O interactions, formingR22(10) hydrogen-bonding motifs, which build up a chain along thecaxis.
CSR, human rights abuse and sustainability report accountability
Authors: Emeseh Engobo , Songi Ondotimi 
Published: February 2014

Purpose– CSR within a purely voluntary context has so far not made meaningful contributions to the problem of corporate environmental and human rights abuses in Africa. The paper therefore aims to improve the effectiveness of CSR in the continent by making companies accountable for the veracity of statements they have voluntarily put out in the public domain.Design/methodology/approach– The paper adopts the stakeholder and legitimacy theories and information regulation as its framework of analysis. Following a discourse on the developments in and limitations of sustainability, the paper constructs an argument in line with these theories how these reports can still be utilised to make meaningful contribution towards strengthening CSR through accountability for false and misleading statements.Findings– Corporations have a stake in information in sustainability reports with regard to their corporate image and reputation. Therefore, under the appropriate framework, utilising corporate accountability for false and misleading statements by companies has promise for making CSR more effective.Research limitations/implications– The main limitations of this research is the political will of national governments in Africa to undertake such an exercise and the relative ability of civil society groups in light of the power of corporations to effectively hold them to account through the models proposed.Originality/value– The paper is interdisciplinary, drawing upon both management and legal theories. A significant contribution of this research is its pragmatic approach which goes beyond calling for legal platform for CSR by recommending a model for accountability within the existing voluntary CSR framework.
The governance of corporate social responsibility
Authors: Uzoma Ihugba Bethel 
Published: February 2014

Purpose– This paper aims to examine the limitations of promoting corporate social responsibility (CSR) regulation and suggests a model for improving accountability in CSR practices through stakeholder engagement-based inclusive regulation framework that is effective, coherent and responsive.Design/methodology/approach– This conceptual paper uses desk-based research to analyse extant literature on the concept of regulation of CSR by looking at examples, benefits and limitations before proposing a framework for improving CSR regulation.Findings– The paper finds that the system of promoting CSR through self-regulation or introducing prescriptive regulation without sustainable stakeholder engagement is ineffective and inefficient.Originality/value– The paper is original in its development of a new framework of “Inclusive Regulation” as a strategy for limiting the shortcomings of prescriptive regulation and enhancing self-regulation as CSR tools. It thus contributes to both theoretical and policy perspective in the enhancement of prescriptive and self-regulation in CSR-regulation discourse.
Social climate in Learning Disability services
Authors: Willets Laura , Mooney Paul , Blagden Nicholas 
Published: February 2014

Purpose
– The social climate of psychiatric institutions correlates with multiple outcomes related to staff and patients. Research into social climate in Learning Disability services is limited. Staff and patients in Learning Disability services have documented both positive and negative experiences. No research has directly compared the social climate of Learning Disability and non-Learning Disability psychiatric services. The purpose of this paper is to understand how these compare. The study will also compare staff and patient views of social climate and the impact of security on social climate in Learning Disability services.

Design/methodology/approach
– A total of 64 patients and 73 staff, from Learning Disability and non-Learning Disability psychiatric hospitals completed the Essen Climate Evaluation Schema (EssenCES) measure of social climate.

Findings
– Patients in Learning Disability and non-Learning Disability services did not differ in their perceptions of social climate. Staff in non-Learning Disability services had a more positive perception of social climate than staff in Learning Disability services. Patients and staff did not differ in their views on climate. Security was negatively related to patients’ Experienced Safety.

Originality/value
– The findings suggest that staff perceive that the deficits associated with Learning Disabilities may limit patients’ therapeutic experience and relationships with their peers. Despite this, patients with Learning Disabilities feel supported by their peers, have positive views of the treatment process and feel as safe as non-Learning Disabled psychiatric patients.
