Better understanding the perceptions of organizational politics: its impact under different types of work unit structure

ABSTRACT Research has uncovered inconsistent results regarding the influence of the perceptions of organizational politics (POP) on employee job performance, suggesting the existence of boundary conditions for such an influence. Drawing from uncertainty management theory, we investigated the interaction effect of POP and work unit structure on job performance, and examined the mediating role of taking charge. We tested the theoretical model with data gathered across three phases over 6 months from 577 individuals and their supervisors in 133 work units. Results showed that when the unit operated an organic structure, POP was significantly negatively related to job performance. In contrast, results demonstrated that when the unit operated a mechanistic structure, POP was significantly positively related to job performance. Furthermore, the results of the mediated moderation analysis revealed that POP was negatively associated with job performance through taking charge in an organic structure, and the indirect effect disappeared in a mechanistic structure.
The Geometry of R{covered foliations

We study R{covered foliations of 3{manifolds from the point of view of their transverse geometry. For an R{covered foliation in an atoroidal 3{manifold M , we show that f M can be partially compactied by a canonical cylinder S 1 R on which 1(M ) acts by elements of Homeo(S 1 )Homeo(R), where the S 1 factor is canonically identied with the circle at innity of each leaf of e F . We construct a pair of very full genuine laminations transverse to each other and to F , which bind every leaf of F . This pair of laminations can be blown down to give a transverse regulating pseudo-Anosov flow for F , analogous to Thurston’s structure theorem for surface bundles over a circle with pseudo-Anosov monodromy. A corollary of the existence of this structure is that the underlying manifold M is homotopy rigid in the sense that a self-homeomorphism homotopic to the identity is isotopic to the identity. Furthermore, the product structures at innity are rigid under deformations of the foliation F through R{covered foliations, in the sense that the representations of 1(M )i nHomeo((S 1 )t) are all conjugate for a family parameterized by t. Another corollary is that the ambient manifold has word-hyperbolic fundamental group. Finally we speculate on connections between these results and a program to prove the geometrization conjecture for tautly foliated 3{manifolds.

False resurrections: Distinguishing regenerated from spared axons in the injured central nervous system

Several recent studies report that axon regeneration can be induced in the mature mammalian nervous system by novel treatments or genetic manipulations. In assessing these reports, it is important to be mindful of the history of regeneration research, which is littered with the corpses of studies that reported regeneration that later proved incorrect. One important reason is the “spared axon conundrum,” in which axons that survive a lesion are mistakenly identified as having regenerated. Here, we illustrate the problem and propose criteria that may be used to identify regenerated vs. spared axons, focusing on the injured spinal cord. J. Comp.

Building brand equity with environmental communication: an empirical investigation in France

Purpose Using Keller's (1993, 2003) brand equity framework, this paper investigates the impact of the firm's environmental communication on brand equity, and specifically its impact on brand image, through the strength and favourability of brand environmental associations. Design/methodology/approach A between-subjects experimental design tests the hypotheses with a generalisable sample of 165 French consumers. Findings Environmental communication positively influences the strength and favourability of brand environmental associations, therefore improving brand equity. Two moderators reinforce the impact of environmental communication on brand equity through the strength of brand environmental associations: the perceived congruence between the brand and the cause, and the perceived credibility of the claim. Practical implications In the context of greater consumer pressure regarding business ethics, managers should favour environmental arguments in their corporate communication to improve brand image through societal associations. Doing so, they should focus their communication on causes that are congruent with their brands to facilitate brand equity building, and ensure they are credible when proclaiming these arguments. Originality/value of paper Despite existing research on corporate social responsibility (CSR), no studies focus on the specific impact of CSR communication on brand equity. This research provides initial empirical evidence about the positive effect of environmental claims on customer-based brand equity.
Dysgenic Fertility in the Russian Federation

Data are reported for intelligence and fertility in the Russian Federation. There was a statistically significant negative correlation for 29 provinces showing dysgenic fertility for intelligence in contemporary Russia. The negative relationship between test score and number of children was observed at the individual level as well. This relationship is not linear: only third and higher order births are associated with lower intelligence. Dysgenic fertility for intelligence was greater for men than for women, mainly because Raven scores of childless women were slightly lower than those of women with one or two children.
Does Grammar Constrain Statistical Learning?

Many studies indicate that statistical learning plays an important role in language acquisition (Saffran & Sahni, in press). Bonatti, Peña, Nespor, and Mehler (2005) presented evidence that such learning is guided by innate grammatical knowledge, a potentially important discovery. Here we provide data suggesting that their results may instead have resulted from facts about French that can be learned from experience. In the study by Bonatti et al. (2005), subjects learned an artificial language in which the words were strings of alternating consonants (C) and vowels (V): CVCVCV (e.g., puragi). In one condition, transition probabilities between consonants within a word were 1.0, but vowels varied: For example, the consonants p_R_g_ appeared only in that order, but each blank could be filled by multiple vowels. In a second condition, within-word transition probabilities between vowels were 1.0, and consonants varied (e.g., _u_e_ã). The key finding was that subjects picked up on the statistical regularity for consonants, but not vowels.
Hypermutation of Immunoglobulin Genes in Memory B Cells of DNA Repair–deficient Mice

To investigate the possible involvement of DNA repair in the process of somatic hypermutation of rearranged immunoglobulin variable (V) region genes, we have analyzed the occurrence, frequency, distribution, and pattern of mutations in rearranged Vλ1 light chain genes from naive and memory B cells in DNA repair–deficient mutant mouse strains. Hypermutation was found unaffected in mice carrying mutations in either of the following DNA repair genes: xeroderma pigmentosum complementation group (XP)A and XPD, Cockayne syndrome complementation group B (CSB), mutS homologue 2 (MSH2), radiation sensitivity 54 (RAD54), poly (ADP-ribose) polymerase (PARP), and 3-alkyladenine DNA-glycosylase (AAG). These results indicate that both subpathways of nucleotide excision repair, global genome repair, and transcription-coupled repair are not required for somatic hypermutation. This appears also to be true for mismatch repair, RAD54-dependent double-strand–break repair, and AAG-mediated base excision repair.
‘You're not really a visitor, you're just a friend’: how older volunteers navigate home visiting

ABSTRACT At the intersection of increasing social support needs due to population ageing and the promotion of older age as a time of contribution and social connection, volunteering is an important focus with advantages for older people. One service that addresses both these imperatives is home visiting services. Home visiting services connect home visitors with isolated older people. To examine how older people navigate volunteering for a home visiting service, six visitors were interviewed and the interviews were analysed using discourse analysis. A professionalism discourse was used to construct home visiting as a structured social support service that improved the lives of isolated older people. A personal relationship discourse constructed home visiting as an opportunity to forge long-term relationships that benefit both parties. At times these two discourses created tension for home visitors. Examining how the home visiting service is described by the service organisation online explains these tensions. The online materials construct active older volunteers as providing professional services while those they visit are constructed as receiving friendship. These discourses provide different ageing identities for visitors from those they visit, which contributes to the difficulties in navigating home visiting services. Addressing these tensions will enable service co-ordinators to better meet the needs of both visitors and clients in the context of increasing need for such services.
Decremental dynamic connectivity

Abstract We consider Las Vegas randomized dynamic algorithms for on-line connectivity problems with deletions only. In particular, we show that starting from a graph with m edges and n nodes, we can maintain a spanning forest during m deletions in O ( m log( n 2 / m ) + n(log n ) 3 (log log n ) 2 ) expected time, which is O ( m ) if m = Θ( n 2 ) and O ( m log n ) if m = Ω( n (log n log log n ) 2 ). The deletions may be interspersed with connectivity queries, each of which is answered in constant time. The previous best bound was O ( m log 2 n ) by Henzinger and Thorup which covered both insertions and deletions. The result is based on a general randomized reduction for edge connectivity problems of many deletions-only queries to a few deletions and insertions queries. For 2-edge connectivity, the complexity is improved from O ( m (log n ) 5 ) to O ( m log( n 2 / m ) + n (log n ) 6 (log log n ) 2 ). For the general decremental k -edge-connectivity problem, we get a total running time of O ( k 2 n 2 polylog n ). Here the previous best bound was O ( kmn polylog n ). Improved running times are also achieved for the static consensus tree problem, with applications to computational biology and relational data bases.
High Correlation between Incoming and Outgoing Activity: A Distinctive Property of Online Social Networks?

User influence is an important topic of research for online social networks. Recent work has shown that a user's influence is not directly related with node in-degree. However, the definition of what is an influential or relevant user is still an open subject. In general, we can say that an influential user has the ability to produce incoming activity in an interaction graph. For this reason we have focused our attention on the user's incoming activity and the search for which factors are related with this indicator. We have studied a Facebook dataset and have found that outgoing activity is highly correlated with incoming activity. This characteristic is valid not only for users with a low level of activity, but it is also valid for high activity users. This result hasn't been reported before and appears to be an important factor of user behavior. To contrast this finding, we have compared it against a popular e-mail dataset and a Twitter dataset. The result was that we found a similar behavior for the Twitter Dataset, but for the e-mail dataset the correlation was lower. Hence, we conjecture that the high correlation may be a distinctive property of social networks. In our future work, we propose to extend this study to other social network platforms.
Metro: Measuring Error on Simplified Surfaces

This paper presents a new tool, Metro, designed to compensate for a deficiency in many simplification methods proposed in literature. Metro allows one to compare the difference between a pair of surfaces (e.g. a triangulated mesh and its simplified representation) by adopting a surface sampling approach. It has been designed as a highly general tool, and it does no assumption on the particular approach used to build the simplified representation. It returns both numerical results (meshes areas and volumes, maximum and mean error, etc.) and visual results, by coloring the input surface according to the approximation error.
Glycated hemoglobin for the diagnosis of diabetes and prediabetes: Diagnostic impact on obese and lean subjects, and phenotypic characterization

Measurement of glycated hemoglobin (HbA1c) has been recommended for the diagnosis of diabetes and prediabetes. However, epidemiological studies have shown significant discordance between HbA1c and glucose‐based tests. Of the factors that could influence agreement between HbA1c and the oral glucose tolerance test (OGTT), bodyweight has not been fully evaluated. The aims of the present study were to evaluate the impact of HbA1c criteria to diagnose diabetes and prediabetes compared with OGTT, and to examine HbA1c in relation to body mass index.
Gauging the twisted Poincaré symmetry as a noncommutative theory of gravitation

Einstein's theory of general relativity was formulated as a gauge theory of Lorentz symmetry by Utiyama in 1956, while the Einstein-Cartan gravitational theory was formulated by Kibble in 1961 as the gauge theory of Poincare transformations. In this framework, we propose a formulation of the gravitational theory on canonical noncommutative space-time by covariantly gauging the twisted Poincare symmetry, in order to fulfil the requirement of covariance under the general coordinate transformations, an essential ingredient of the theory of general relativity. It appears that the twisted Poincare symmetry cannot be gauged by generalizing the Abelian twist to a covariant non-Abelian twist, nor by introducing a more general covariant twist element. The advantages of such a formulation as well as the related problems are discussed and possible ways out are outlined.
An examination of body size discrepancy for female college students wanting to be fashion models

ABSTRACT This study is designed to understand body sizes of female college students wanting to be fashion models. Also, this study examines body size discrepancies between the actual and perceived body sizes for college students involved in fashion. Data were collected from 127 female college students who applied to be fashion models. The actual body dimensions were assessed with Body Mass Index weight status, and ASTM D 5585-11e1 standard size charts for adult female misses figure types. The result indicates that college students with fashion involvement tend to be confident about their body sizes. They seem to know or pretend not to know about their body sizes. Although this might be related to current inconsistent sizing systems in the apparel industry, we found that students involved in fashion have a discrepancy between the actual and perceived body sizes. This result is beneficial to the fashion industry’s understanding of the young generation.
Son Preference in Pakistan; A Myth or Reality

Objective: To analyze desire for sons/daughters among ladies of Peshawar, Pakistan, with a view to rule out son preference and to study impact of various demographic characteristics on the subject. Methods: Cross-sectional descriptive study conducted at Combined Military Hospital, Peshawar, from August 2015 - January 2016; sampling technique was random/probability/non-purposive. Self-designed questionnaire was utilized; carrying questions pertinent to desire for sons/daughters during marital life, and demographic details. Data analyzed via descriptive analysis (SPSS-21), expressed as frequencies/percentages and mean ± standard deviation(minimum/maximum). Sons and daughters desired (dependent variables) were cross-tabulated with independent variables. Results: Response rate was 63.25% (n-506). Data revealed following: Sons desired 3.05±2.061(1/12); Daughters desired 1.15±0.767(0/4); 6.1%(n-31) and 0.6%(n-3) desired infinite number of sons and daughters respectively, 18.2%(n-92) did not desire to have even one daughter, while 2.2%(n-11) considered it immaterial to have daughters or sons. There was a significant relation between sons desired and client’s education (p<0.001), husband’s education (p<0.001) and socioeconomic class (p<0.001). There was no significant impact of religion (p-0.142) on desire for sons. Impact of independent variables on daughters desired was similar but less pronounced. Conclusion: There was candid son preference among the respondents. Gender discrimination can be attenuated by adequately addressing son preference at all tiers.
Screening Twitter Users for Depression and PTSD with Lexical Decision Lists

This paper describes various systems from the University of Minnesota, Duluth that participated in the CLPsych 2015 shared task. These systems learned decision lists based on lexical features found in training data. These systems typically had average precision in the range of . 70 ‐ . 76, whereas a random baseline attained . 47 ‐ . 49.
A Rare Case of Congenital Simple Cystic Ranula in a Neonate

Congenital ranula in a neonate is an uncommon occurrence. We present one such case of the said lesion where the clinical presentation and management were found to be interesting, hitherto unreported in the medical literature. This clinical record also reviews the scant medical literature on congenital ranula in neonates.
Evaluating Emergent Naming Relations Through Representational Drawing in Individuals With Developmental Disabilities Using the PEAK-E Curriculum

Naming has been described behavior analytically as the ability to engage in both speaker and listener behavior as they relate to stimuli in the real world, where speaker behavior is often demonstrated in the form of tacting and listener behavior in the form of selection-based responding. The present study sought to evaluate representational drawing as an alternative to selection-based listener responding where the listener behavior is unprompted. A multiple-baseline with an embedded multiple probe design was conducted across 3 individuals with developmental disabilities, and tact/drawing stimuli included unfamiliar animal blends. The results suggested that, following tact training, all of the participants demonstrated the untrained emergence of representational drawing of the blended animal pictures. The procedures and stimuli in the present study were taken from the PEAK-E curriculum, allowing for potentially easier replication by practitioners and researchers.
Efficiently Extracting Relationships From Natural Language

Minerva aims to quickly extract relationship tuples of the form 〈object, relationship, object〉 from large corpora such that they can later be explored by a user or data-mining program. A custom noun-phrase chunker allows the system to identify candidate relationships. These candidates are then either accepted or rejected by a classifier trained using manually-labeled relationships. Minerva was evaluated using a dataset consisting of headlines taken from recently popular articles on Digg.com. Introduction A large body of 〈object, relationship, object〉 tuples extracted from a corpus may make it possible to answer certain queries more easily than keyword search. Examples include discovering an unknown relationship between two known objects (i.e. How are Linux and UNIX related? ), or finding unknown objects related to a known object in a particular way (i.e. What is Lawrence Lessig a proponent of? ). Minerva’s approach to extraction is similar to that of TextRunner (Etzioni et al. 2008). Both systems share the philosophy of performing ‘best-effort’ extraction on a large volume of data in a ‘single-pass’. Notably, TextRunner ‘bootstraps’ itself by automatically generating data of reasonable quality to train a classifier to grade candidate relationships. Having been developed in just a few weeks, Minerva simply uses manually-labeled data. Another interesting contrast is Minerva’s use of SVM to classify relationships instead of naive Bayes. Copyright c © 2009, Association for the Advancement of Artificial Intelligence (www.aaai.org). All rights reserved. Architecture Overview First, text was downloaded and a list of candidate relationships extracted from it ([d]). Then, a user labeled each relationship tuple as good or bad, creating a training set ([d, y]). A function (x()) was designed to represent a tuple so a SVM’s parameters ([θ]) could be trained to recognize good relationships.
Motivational patterns as an instrument for predicting success in promising young football players

Abstract Psychological characteristics are crucial to identifying talents, which is why these are being incorporated in today’s multidimensional talent models. In addition to multidimensionality, talent studies are increasingly drawing on holistic theories of development, leading to the use of person-oriented approaches. The present study adopts such an approach by looking at the influence that motivational characteristics have on the development of performance, in a person-oriented way. For this purpose, it looks at how the constructs achievement motive, achievement goal orientation and self-determination interact with one another, what patterns they form and how these patterns are linked to subsequent sports success. Ninety-seven top young football players were questioned twice. Another year later, it was enquired which of these players had been selected for the U15 national team. At both measuring points, four patterns were identified, which displayed a high degree of structural and individual stability. As expected, the highly intrinsically achievement-oriented players were significantly more likely to move up into the U15 national team. The results point to the importance of favourable patterns of motivational variables in the form of specific types, for medium-term performance development among promising football talents, and thus provide valuable clues for the selection and promotion of those.
Oncogenic MicroRNAs Characterization in Clear Cell Renal Cell Carcinoma

A key challenge for the improvement of clear cell renal cell carcinoma (ccRCC) management could derive from a deeper characterization of the biology of these neoplasms that could greatly improve the diagnosis, prognosis and treatment choice. The aim of this study was to identify specific miRNAs that are deregulated in tumor vs. normal kidney tissues and that could impact on the biology of ccRCC. To this end we selected four miRNAs (miR-21-5p, miR-210-3p, miR-185-5p and miR-221-3p) and their expression has been evaluated in a retrospective cohort of formalin-fixed paraffin-embedded (FFPE) tissues from 20 ccRCC patients who underwent surgical nephrectomy resection. miR-21-5p and miR-210-3p resulted the most significantly up-regulated miRNAs in this patient cohort, highlighting these onco-miRNAs as possible relevant players involved in ccRCC tumorigenesis. Thus, this study reports the identification of specific oncogenic miRNAs that are altered in ccRCC tissues and suggests that they might be useful biomarkers in ccRCC management.
