Generalized Wavefunctions for Correlated Quantum Oscillators IV: Bosonic and Fermionic Gauge Fields

The unitary Clifford algebras are described here for the first time, and arise from the intersection of the orthogonal and common symplectic (Weyl) Clifford algebras of the complexification of the canonical phase space. The convergence of the exponential map is possible in available topologies in our constructions, but it does not converge without additional assumptions in general. Continuous dynamics exists only in semigroups. A well defined spin geometry exists for the unitary Clifford algebras in the appropriate Witt basis, which also affords us both bosonic and fermionic representations through alternative topological completions of the same structure, and physically represent the stable states of the system. Unitary Clifford algebras can be used to define dynamical gauge bundles for arbitrary numbers of correlated (unified) fields. The generic dynamical gauge group for four pairs of canonical variables (four fields) is shown to be isomorphic to $U(4)\times U(4)$, with the spectrum effectively determined by $S[U(4)\times U(3) \times U(1)]$ due to the constraint of geodesic transport of the generators of the dynamical group. This includes prediction of the existence of chimeric bosons, whose quantum numbers are not covariant so they may appear to have a different identity to different observers.
Resource Mobilization through Ethnic Networks

Shopkeepers have social networks composed of ties to many others: Family, friends, customers, suppliers, employees, and moneylenders. We examine how ties to family and friends affect three aspects of entrepreneurship for Asian and white shop owners in four English cities: Business foundings, business success, and business turnover. Social ties are important for all three processes in both groups. An implication of our research is that the comparative study of immigrant and native groups shifts the focus from group differences to group similarities. Studies examining only immigrants may find apparently distinctive characteristics, but, in fact, many traits are common to all small-business owners, given the turbulent environment they face.
Answering Natural Language Questions on RDF Knowledge base in French

While SPARQL is a powerful way of accessing linked data, using natural language is more intuitive for most users. A few question answering systems already exist for English, but none for French. Our system allows a user to query the DBpedia knowledge by asking questions in French, which are automatically translated into SPARQL queries. The system classifies questions by various types that are resolved by type specific heuristics. To our knowledge, this is the first French-based question answering system in the QALD competition.
Economic Impact of Combining Metformin with Dipeptidyl Peptidase-4 Inhibitors in Diabetic Patients with Renal Impairment in Spanish Patients

Background To evaluate resource use and health costs due to the combination of metformin and dipeptidyl peptidase-4 (DPP-4) inhibitors in patients with diabetes and renal impairment in routine clinical practice. Methods An observational, retrospective study was performed. Patients aged ≥30 years treated with metformin who initiated a second oral antidiabetic treatment in 2009 to 2010 were included. Two groups of patients were analysed: metformin+DPP-4 inhibitors and other oral antidiabetics. The main measures were: compliance, persistence, metabolic control (glycosylated hemoglobin< 7%) and complications (hypoglycemia, cardiovascular events) and total costs. Patients were followed up for 2 years. Results We included 395 patients, mean age 70.2 years, 56.5% male: 135 patients received metformin+DPP-4 inhibitors and 260 patients received metformin+other oral antidiabetics. Patients receiving DPP-4 inhibitors showed better compliance (66.0% vs. 60.1%), persistence (57.6% vs. 50.0%), and metabolic control (63.9% vs. 57.3%), respectively, compared with those receiving other oral antidiabetics (P<0.05), and also had a lower rate of hypoglycemia (20.0% vs. 47.7%) and lower total costs (€ 2,486 vs. € 3,002), P=0.001. Conclusion Despite the limitations of the study, patients with renal impairment treated with DPP-4 inhibitors had better metabolic control, lower rates (association) of hypoglycaemia, and lower health costs for the Spanish national health system.
Kurt Lewin and the planned approach to change: A re-appraisal

The work of Kurt Lewin dominated the theory and practice of change management for over 40 years. However, in the past 20 years, Lewin's approach to change, particularly the 3-Step model, has attracted major criticisms. The key ones are that his work: assumed organizations operate in a stable state; was only suitable for small-scale change projects; ignored organizational power and politics; and was top-down and management-driven. This article seeks to re-appraise Lewin's work and challenge the validity of these views. It begins by describing Lewin's background and beliefs, especially his commitment to resolving social conflict. The article then moves on to examine the main elements of his Planned approach to change: Field Theory; Group Dynamics; Action Research; and the 3-Step model. This is followed by a brief summary of the major developments in the field of organizational change since Lewin's death which, in turn, leads to an examination of the main criticisms levelled at Lewin's work. The article concludes by arguing that rather than being outdated or redundant, Lewin's approach is still relevant to the modern world. Copyright Blackwell Publishing Ltd 2004.
Counterproductive Work Behavior Among White-Collar Employees: A Study from Turkey

The current study was designed to evaluate the magnitude and types of counterproductive work behaviors (CWBs) among a group of white-collar employees from different firms. A total of 766 employees voluntarily participated in our study. We focused especially on employees' perceptions of their work environment and on their affective responses to those perceptions. Data were dependent on self-reporting and privacy, and anonymity measures were taken into account. The five different instruments used to evaluate job satisfaction were, organizational constraints, interpersonal conflict, quantitative workload and CWB. We found a high degree of job satisfaction, a minimal quantitative workload and a limited exhibition of CWBs among our sample. Organizational constraints were found to be the most strongly correlated to exhibited CWBs, followed by interpersonal conflict and quantitative workload. Job satisfaction had a diminishing effect on CWBs. Among the five dimensions of CWBs, abuse and withdrawal were found to be the most important. The most frequently reported CWB was ‘came to work late without permission. ’ Except for income we found no statistically significant relationship between demographic characteristics and the exhibition of CWBs. We concluded that by abolishing pre-existing organizational constraints there may be a reduction in CWBs.
Inhibition of interferon-beta responses in multiple sclerosis immune cells associated with high-dose statins.

OBJECTIVE To determine whether statins affect type 1 interferon responses in relapsing-remitting multiple sclerosis (RRMS). DESIGN Study effects of atorvastatin on type 1 interferon responses in Jurkat cells, mononuclear cells (MNCs) from therapy-naive patients with RRMS in vitro, and MNCs from interferon-treated RRMS patients in vivo in 4 conditions: no drug, statin only, interferon-beta only, and statin added on to interferon-beta therapy. PATIENTS The study examined clinically stable patients with RRMS: 21 therapy-naive patients and 14 patients receiving interferon-beta with a statin. INTERVENTIONS Statin effects on in vitro and in vivo interferon-beta-induced STAT1 transcription factor activation, expression of interferon-stimulated proteins in MNCs, and serum type 1 interferon activity. RESULTS In vitro, atorvastatin dose dependently inhibited expression of interferon-stimulated P-Y-STAT1 by 44% (P < .001), interferon regulatory factor 1 protein by 30% (P=.006), and myxovirus resistance 1 protein by 32% (P=.004) compared with no-statin control in MNCs from therapy-naive RRMS patients. In vivo, 9 of 10 patients who received high-dose statins (80 mg) had a significant reduction in interferon-beta therapy-induced serum interferon-α/β activity, whereas only 2 of 4 patients who received medium- dose statins (40 mg) had reductions. High-dose add-on statin therapy significantly blocked interferon-beta function, with less P-Y-STAT1 transcription factor activation, and reduced myxovirus resistance 1 protein and viperin protein production. Medium doses of statins did not change STAT1 activation. CONCLUSIONS High-dose add-on statin therapy significantly reduces interferon-beta function and type 1 interferon responses in RRMS patients. These data provide a putative mechanism for how statins could counteract the beneficial effects of interferon-beta and worsen disease.
Inter-individual variability in right ventricle adaptation after an endurance race

Background Right ventricle (RV) dysfunction has been described in athletes after endurance races. We aimed to understand and characterize the RV response to endurance exercise, the impact of individual variability and the effects of the amount of exercise. Methods and results Echocardiography was performed in 55 healthy adults at baseline and after a three-stage trail race: short (14 km; n = 17); medium (35 km; n = 21); and long (56 km; n = 17). Standard and speckle tracking echocardiographic assessment of the RV was performed with global and separate analysis of the RV basal (inflow) and apical regions. Although no change was observed in the short distance runners, the RV systolic deformation decreased significantly (p < 0.05) after both the medium length and long races (Δ% RV global strain −7.6 ± 20.1 and −8.7 ± 21.8, respectively) with significant RV dilatation (Δ% RV volume +10.6 ± 9.9 and +15.3 ± 12.8, respectively). The RV basal segment made a major contribution to stroke volume during exercise, showing larger increases in size and strain compared with the apex. Various patterns of RV adaptation to exercise, ranging from increases in both RV segmental strains and sizes to an insufficient increase in size and a decrease in strain, were identified; this individual variability was not correlated with prior training. Conclusion An acute RV impairment was demonstrated after a trail-running race and was related to the amount of exercise. A high inter-individual variability was observed. Differences in RV adaptation patterns were independent of prior training, suggesting the influence was due to other individual factors.
Freezing effects and objects1

This paper is an investigation of freezing effects, that is, cases where an element (e.g. an object or a subject, or an element within it) is unable to move from a certain structural position. An account of the most prominent properties of freezing in Norwegian is followed by a comparative study of primarily English and Norwegian indirect objects, with important consequences for the general approach to indirect objects. Although recent analyses capture central properties of indirect objects, they fall short of accounting for freezing properties, seen here in terms of agreement properties, most notably Case agreement. It is shown that both subjects and indirect objects disallow sub-extraction in both English and Norwegian; however, unlike English, Norwegian allows the indirect object to A-bar move. This relates to the question of whether Case is structural or inherent. As such, this paper offers a new argument in favor of Case as a central ingredient in deriving freezing effects.
Social Class in Applied Linguistics

ABSTRACT Social class is a curious construct. In the discipline where it has traditionally been most at home, sociology, there has been a constant flow of commentary on its demise and, indeed, its death over the years. In applied linguistics, the situation is somewhat different in that there has been a degree of social class denial, but more importantly, there has been social class erasure in that the construct has tended to receive little or no attention in publications that deal with language and identity and social life. Where social class is introduced into research, it is almost always done in a very cursory, partial, and superficial way. Still, there has been some research examining the interrelationship between social class and language over the years, and in this article, I provide a review of that research, focusing primarily on the period 2000–2014. First, however, I include a discussion of what social class means in 21st-century societies and a short review of class-based research carried out from the 1960s to the 1990s, the inclusion of the latter being necessary to an understanding of research after 2000. I conclude the article with some thoughts about future directions.
Self‐involvement, intention certainty and attitude—intention consistency

The relationship of two qualities of the attitude structure, namely self-involvement and intention certainty, with the consistency of the attitude—intention, subjective norm-intention and direct experience—intention relations was investigated. Self-involvement exerted a moderating effect upon the direct experience—intention and the subjective norm—intention relations, but not on the attitude—intention relation. Although some earlier research used direct experience as an indicator of self-involvement, it was shown that, as hypothesized, the two variables correlate only modestly. Certainty about intention was, as hypothesized, connected with higher consistency between intentions on the one hand and attitudes, subjective norms and direct experience on the other hand.
Stability and change in parenting beliefs in first-time mothers from the pre- to postnatal period

A total of 103 prospective first-time mothers completed measures of parenting beliefs, depressive symptomatology, personality, social support and attachment style at 20 weeks prepartum (T1), and were asked to complete various measures again at 6 months postnatally (T2). There were significant changes in parenting beliefs in an adaptive direction, with mean scores for 'nurturance' and 'knowledge of social learning theory' increasing, and scores for 'restrictiveness', 'authoritarianism', 'punitiveness' and 'role reversal' decreasing. Scores on each belief measure at T2 were predicted by the corresponding score at T1, with other measures at T1 explaining further variance for particular beliefs at T2. The implications of these findings for those supporting first-time mothers and directions for future research are discussed.
Cranial and cervical nerve injuries after repeat carotid endarterectomy.

BACKGROUND AND PURPOSE The incidence of cranial and/or cervical nerve injuries after primary carotid endarterectomy (CEA) ranges from 3% to 48%; however, the clinical outcome of these injuries after repeat CEA has not been thoroughly analyzed in the English-language medical literature. This prospective study analyzes the incidence and outcome of cranial nerve injuries after repeat CEA. PATIENTS AND METHODS This study includes 89 consecutive patients who had repeat CEAs. Preoperative and postoperative cranial nerve evaluations were performed, including clinical examinations (neurologic) and direct laryngoscopy. Patients with vagal or glossopharyngeal nerve injuries also underwent comprehensive speech evaluations, video stroboscopy, fluoroscopy, and methylene blue testing for aspiration. Patients with postoperative cranial nerve injuries were followed up for a long time to assess their recovery. RESULTS Twenty-five cranial and/or cervical nerve injuries were identified in 19 patients (21%). They included 8 hypoglossal nerves (9%), 11 vagal nerves or branches (12%) (6 recurrent laryngeal nerves [7%], 3 superior laryngeal nerves [3%], and 2 complex vagal nerves [2%]), 3 marginal mandibular nerves (3%), 2 greater auricular nerves (2%), and 1 glossopharyngeal nerve (1%). Twenty-two (88%) of these injuries were transient with a complete healing time ranging from 2 weeks to 28 months (18 of 22 injuries healed within 12 months). The remaining three injuries (12%) were permanent (1 recurrent laryngeal nerve, 1 glossopharyngeal nerve, and 1 complex vagal nerve injury). The recurrent laryngeal nerve injury had a longer healing time than the other cranial nerve injuries. CONCLUSIONS Repeat CEA is associated with a high incidence of cranial and/or cervical nerve injuries, most of which are transient. However, some of these have a long healing time, and a few can be permanent with significant disability.
Distributed under Creative Commons Cc-by 4.0 Brain-derived Neurotrophic Factor Serum Levels in Genetically Isolated Populations: Gender-specific Association with Anxiety Disorder Subtypes but Not with Anxiety Levels or Val66met Polymorphism

Anxiety disorders (ADs) are disabling chronic disorders with exaggerated behavioral response to threats. This study was aimed at testing the hypothesis that ADs may be associated with reduced neurotrophic activity, particularly of Brain-derived neu-rotrophic factor (BDNF), and determining possible effects of genetics on serum BDNF concentrations. In 672 adult subjects from six isolated villages in NorthEastern Italy with high inbreeding, we determined serum BDNF levels and identified subjects with different ADs subtypes such as Social and Specific Phobias (PHSOC, PHSP), Generalized Anxiety Disorder (GAD), and Panic Disorder (PAD). Analysis of the population as a whole or individual village showed no significant correlation between serum BDNF levels and Val66Met polymorphism and no association with anxiety levels. Stratification of subjects highlighted a significant decrease in serum BDNF in females with GAD and males with PHSP. This study indicates low heri-tability and absence of any impact of the Val66Met polymorphism on circulating concentrations of BDNF. Our results show that BDNF is not a general biomarker of anxiety but serum BDNF levels correlate in a gender-specific manner with ADs subtypes.
Private and Accurate Data Aggregation against Dishonest Nodes

Privacy-preserving data aggregation in ad hoc networks is a challenging problem, considering the distributed communication and control requirement, dynamic network topology, unreliable communication links, etc. The difficulty is exaggerated when there exist dishonest nodes, and how to ensure privacy, accuracy, and robustness against dishonest nodes remains an open issue. Different from the widely used cryptographic approaches, in this paper, we address this challenging problem by exploiting the distributed consensus technique. We first propose a secure consensus-based data aggregation (SCDA) algorithm that guarantees an accurate sum aggregation while preserving the privacy of sensitive data. Then, to mitigate the pollution from dishonest nodes, we propose an Enhanced SCDA (E-SCDA) algorithm that allows neighbors to detect dishonest nodes, and derive the error bound when there are undetectable dishonest nodes. {We prove the convergence of both SCDA and E-SCDA. We also prove that the proposed algorithms are $(\epsilon, \sigma)$-data-privacy, and obtain the mathematical relationship between $\epsilon$ and $\sigma$. } Extensive simulations have shown that the proposed algorithms have high accuracy and low complexity, and they are robust against network dynamics and dishonest nodes.
Skill Development in Different Components of Arithmetic and Basic Cognitive Functions: Findings From a 3-Year Longitudinal Study of Children With Different Types of Learning Difficulties

Arithmetic and cognitive skills of children with mathematical difficulties (MD-only), with comorbid reading difficulties (MD-RD), with reading difficulties (RD-only), and normally achieving children were examined at 3 points from Grades 3-4 to Grades 5-6 (age range, 9-13 years). Both MD groups displayed severe weaknesses in 4 domain-specific arithmetic components (factual, conceptual, procedural, and problem-solving skills) during all 3 measure points. Telling time and approximate arithmetic were also problematic for children with MD. Both MD groups displayed a small weakness related to visual-spatial working memory, and the MD-RD group also displayed small weaknesses related to verbal short-term memory, processing speed, and executive functions. The 4 groups developed at similar rates within all domain-specific components as well as basic cognitive functions. These findings demonstrate that children identified as having MD when they are 9 years old do not catch up with their normally achieving peers in later school grades, when they are 13 years old. They also continue to lag behind their peers with respect to the domain-general cognitive system.
Glass Ceiling or Slippery Floors? Understanding Gender Differences in the Spanish Worker’s Compensation System

The main goal of this paper is to analyse gender differences in the Spanish workplace accident insurance or worker’s compensation (WC) system. More specifically, we are interested in understanding the differences between female and male employees in the duration of the recovery spell after a workplace accident. This will provide us with a better comprehension of the distinct opportunistic behaviour carried by men and women causing absenteeism. Our results show that women who are occupied in low-responsibility jobs experience unjustified longer periods of recovery than men. But, as the occupational ladder is climbed this pattern tends to disappear and, what is more striking, on top of the ladder women are found to be more job-committed than men. Besides, business cycle seems to have a greater effect on women than men.
Stereotype Threat: Are Lower Status and History of Stigmatization Preconditions of Stereotype Threat?

This research extended stereotype-threat effects outside of the academic domain and to a nonstigmatized group. Female and male students performed three decision tasks: lexical, valence, and affective processing. Half of the participants were told that, in general, men are poorer performers than are women in affective processing tasks. No differences between conditions were observed for the lexical and valence tasks. By contrast, for the affective task, threatened men made significantly more errors than did participants in the other three conditions. More precisely, threatened men tended to accept as affective words that were not affective. This latter result suggests that threatened men decreased their threshold for affectivity “to prove” the inapplicability of the stereotype to themselves. Moreover, stereotype endorsement did not mediate the results. Identification with the affective domain, on the other hand, moderated the effect of stereotype threat. Discussion considers the consequences of these findings for everyday interactions.
Resentment, indignation, entitlement the transformation of unconscious wish into need

An underlying premise of this paper is that human beings actively and purposefully impose meanings on their experiences of psychic injury and that these meanings then have important implications for character development. Specifically, the paper examines how individuals, in defensive reaction to psychic injury, may repress their “impossible‐to‐fulfill”; wishes, only to find those wishes eventually reborn as needs. In this way, a person's oppressive cruelty to his own wishes gives rise to resentment, indignation, and entitlement, which, in turn, fuel the experience of need. While wish implicitly communicates a request to receive from another, need, with its vicissitudes of demand and urgency, may do violence to the free social discourse of giving and receiving. The interpersonal field of give‐and‐take may be so constrained by the circular compulsivity of mandated giving and entitled needfulness that it is emptied of any spontaneous desire. The differential impact of communicating needs and wishes on the wi.
