Genetic variants of the FADS gene cluster and ELOVL gene family, colostrums LC-PUFA levels, breastfeeding, and child cognition

Introduction: Breastfeeding effects on cognition are attributed to long-chain polyunsaturated fatty acids (LC-PUFAs), but controversy persists. Genetic variation in fatty acid desaturase (FADS) and elongase (ELOVL) enzymes has been overlooked when studying the effects of LC-PUFAs supply on cognition. We aimed to: 1) to determine whether maternal genetic variants in the FADS cluster and ELOVL genes contribute to differences in LC-PUFA levels in colostrum; 2) to analyze whether these maternal variants are related to child cognition; and 3) to assess whether children's variants modify breastfeeding effects on cognition. Methods: Data come from two population-based birth cohorts (n = 400 mother-child pairs from INMA-Sabadell; and n = 340 children from INMA-Menorca). LC-PUFAs were measured in 270 colostrum samples from INMA-Sabadell. Tag SNPs were genotyped both in mothers and children (13 in the FADS cluster, 6 in ELOVL2, and 7 in ELOVL5). Child cognition was assessed at 14 mo and 4 y using the Bayley Scales of Infant Development and the McCarthy Scales of Children"s Abilities, respectively. Results: Children of mothers carrying genetic variants associated with lower FADS1 activity (regulating AA and EPA synthesis), higher FADS2 activity (regulating DHA synthesis), and with higher EPA/AA and DHA/AA ratios in colostrum showed a significant advantage in cognition at 14 mo (3.5 to 5.3 points). Not being breastfed conferred an 8- to 9-point disadvantage in cognition among children GG homozygote for rs174468 (low FADS1 activity) but not among those with the A allele. Moreover, not being breastfed resulted in a disadvantage in cognition (5 to 8 points) among children CC homozygote for rs2397142 (low ELOVL5 activity), but not among those carrying the G allele. Conclusion: Genetically determined maternal supplies of LC-PUFAs during pregnancy and lactation appear to be crucial for child cognition. Breastfeeding effects on cognition are modified by child genetic variation in fatty acid desaturase and elongase enzymes.

HRM Practices, Intrinsic Motivators, and Organizational Performance in the Public Sector

This article aims to determine the impact of human resource management (HRM) practices on public service motivation (PSM) and organizational performance. Based on a survey of Swiss cantonal public employees (N = 3,131), this study shows that several HRM practices may be considered as organizational antecedents of PSM and strong predictors of perceived organizational performance. Fairness, job enrichment, individual appraisal, and professional development are HRM practices that are positively and significantly associated with PSM and perceived organizational performance. Moreover, these results suggest that HRM practices are stronger predictors than either PSM or organizational commitment when explaining the individual perception of organizational performance.

Rhétorique et cognition : perspectives théoriques et stratégies persuasives

D'une certaine manière, la rhétorique est un art cognitif. L'art de discourir en situation concrète dans l'espoir de faire adhérer l'auditoire à une thèse suppose une forte aptitude cognitive: celle de se représenter la façon dont l'auditoire lui-même se représente une situation rhétorique. Or, à partir du moment où agir sur les représentations d'autrui est facilité par des techniques rhétoriques ou sophistiques, la question de la tromperie verbale s'est immiscée dans des affaires de régulation sociale et, avec elle, des enjeux tant de crédibilité que de crédulité. Dans le cadre démocratique rendant encore plus aiguë une forme de dépendance à l'information d'autrui, la nécessité de croire tout comme la possibilité d'être leurré mettent à l'épreuve tant le fonctionnement social de la Cité que l'évaluation des informations et de leurs auteurs. Le but des contributions de cet ouvrage n'est pas de dénoncer les effets de certains schèmes argumentatifs que d'aucuns jugeraient fallacieux ni d'ajouter une couche nouvelle aux critiques des sophismes, mais d'étudier leur fonctionnement et leurs effets cognitifs hic et nunc. Quels sont les mécanismes langagiers et cognitifs qui expliquent la «performance» des arguments réputés fallacieux? Comment fonctionnent les stratégies rhétoriques à l'intersection entre cognition, sciences du langage et société? Cet ouvrage, issu du colloque Communication et Cognition: manipulation, persuasion et biais dans le langage, tenu à Neuchâtel du 26 au 28 janvier 2011, propose plusieurs propositions originales ou hypothèses stimulantes dans l'espoir qu'elles inspireront tant les chercheurs spécialisés en rhétorique et sciences du langage à aller voir du côté de la psychologie cognitive que les spécialistes de ce domaine à mettre en évidence la rhétoricité de leurs recherches. English version: In a way, rhetoric is a cognitive art. The art of speaking in concrete situations in the hope of gaining the audience's consent on a given issue requires the operation of a cognitive ability: that of being able to represent the way an audience represents itself a rhetorical situation. Nonetheless, once we consider that rhetorical or sophistic techniques influence people's representations, verbal deception becomes a matter of social regulation, together with issues of credibility and credulity. In a democratic context fostering a form of dependence towards other people's information, the necessity of believing everything and the possibility of being duped are challenges for both the social management of the City and the evaluation of information and of its sources. The contribution of the chapters of this volume is neither to be found in the condemnation of the fallacious effects of specific argument schemes nor in the addition of yet another layer to fallacy criticism, but in the study of how fallacies work, hic et nunc. What are the linguistic and cognitive mechanisms at play behind the "performance" of fallacious arguments? How do rhetorical strategies work at the interface of cognition, language science and society? This book gathers papers that were presented during the international conference Communication & Cognition: manipulation, persuasion and biases in language, held at the University of Neuchâtel in January 2011. A number of original proposals and stimulating hypotheses emerge from them: we hope that these will inspire researchers in the language sciences who specialise in rhetoric to take on board cognitive scientific insights but also researchers in cognitive science to engage with the rhetoricity of their own research.

Vision, spatial cognition and intellectual disability.

Vision is the most synthetic sensory channel and it provides specific information about the relative position of distant landmarks during visual exploration. In this paper we propose that visual exploration, as assessed by the recording of eye movements, offers an original method to analyze spatial cognition and to reveal alternative adaptation strategies in people with intellectual disabilities (ID). Our general assumption is that eye movement exploration may simultaneously reveal whether, why, and how, compensatory strategies point to specific difficulties related to neurological symptoms. An understanding of these strategies will also help in the development of optimal rehabilitation procedures.

The organizational structure of online academic advising

Academic advising is a key element for learning success in virtual environments that has received little attention from researchers. This paper focuses on the organizational arrangements needed for the delivery of academic advising in online higher education. We present the general dimensions of organizational structures (division of labor, hierarchy of authority and formalization) and their possible forms when applied to academic advising. The specific solution adopted at the Open University of Catalonia is described and assessed in order to draw general conclusions of interest for other institutions.

Cognition et psychopathologie chez les nonagénaires et centenaires vivant en établisement médico-social gériatrique en Suisse : focalisation sur l'anosognosie = [Cognition and psychopathology in nonagenarians and centenarians living in geriatric nursing homes in Switzerland : a focus on anosognosia]

Les nonagénaires et centenaires voient actuellement leur nombre augmenter considérablement, beaucoup d'entre eux vivant en maison de retraite. Pour cette population, on dispose de très peu de données au sujet de la Symptomatologie psychiatrique et des capacités cognitives autres que mnésiques. Cette étude exploratoire se concentre sur l'anosognosie et ses liens avec les symptômes psychiatriques et cognitifs courants. Cinquante-huit sujets âgés de 90 ans ou plus ont été recrutés dans des établissements médico-sociaux gériatriques et divisés en 5 groupes selon le Mini Mental State Examination (MMSE). Les évaluations incluent le test des 5 mots, le CLOX, les fluences lexicales et catégorielles, le questionnaire d'anosognosie- démence (AQ-D), l'inventaire neuropsychiatrique (NPI) et l'index de comorbidité de Charlson. Les sujets étudiés présentent une atteinte cognitive modérée, le MMSE moyen (±DS) étant à 15.41 ± 7.04. L'anosognosie augmente avec l'atteinte cognitive, étant associée avec tous les domaines cognitifs, mais aussi avec les symptômes psychopathologiques d'apathie et d'agitation. Les sujets ayant une atteinte cognitive légère semblent moins anosognosiques que ceux avec l'atteinte cognitive la plus faible ou ceux ne présentant aucune atteinte. Ni l'anosognosie ni les symptômes psychopathologiques ne sont liés aux comorbidités somatiques. Chez les résidents très âgés étudiés vivant en maison de retraite, l'anosognosie est principalement légère. Elle est associée à des changements cognitifs, mais aussi psychopathologiques. Des investigations supplémentaires sont toutefois nécessaires pour déterminer s'il existe un lien causal entre l'anosognosie et les atteintes psychopathologiques.

Competitor Information andCompetitive Knowledge Management in a Large Industrial Organization

Thisthesis supplements the systematic approach to competitive intelligence and competitor analysis by introducing an information-processing perspective on management of the competitive environment and competitors therein. The cognitive questions connected to the intelligence process and also the means that organizational actors use in sharing information are discussed. The ultimate aim has been to deepen knowledge of the different intraorganizational processes that are used in acorporate organization to manage and exploit the vast amount of competitor information that is received from the environment. Competitor information and competitive knowledge management is examined as a process, where organizational actorsidentify and perceive the competitive environment by using cognitive simplification, make interpretations resulting in learning and finally utilize competitor information and competitive knowledge in their work processes. The sharing of competitive information and competitive knowledge is facilitated by intraorganizational networks that evolve as a means of developing a shared, organizational level knowledge structure and ensuring that the right information is in the right place at the right time. This thesis approaches competitor information and competitive knowledge management both theoretically and empirically. Based on the conceptual framework developed by theoretical elaboration, further understanding of the studied phenomena is sought by an empirical study. The empirical research was carried out in a multinationally operating forest industry company. This thesis makes some preliminary suggestions of improving the competitive intelligence process. It is concluded that managing competitor information and competitive knowledge is not simply a question of managing information flow or improving sophistication of competitor analysis, but the crucial question to be solved is rather, how to improve the cognitive capabilities connected to identifying and making interpretations of the competitive environment and how to increase learning. It is claimed that competitive intelligence can not be treated like an organizational function or assigned solely to a specialized intelligence unit.

Modeling and measuring organizational renewal capability

Globalization and new information technologies mean that organizations have to face world-wide competition in rapidly transforming, unpredictable environments, and thus the ability to constantly generate novel and improved products, services and processes has become quintessential for organizational success. Performance in turbulent environments is, above all, influenced by the organization's capability for renewal. Renewal capability consists of the ability of the organization to replicate, adapt, develop and change its assets, capabilities and strategies. An organization with a high renewal capability can sustain its current success factors while at the same time building new strengths for the future. This capability does not only mean that the organization is able to respond to today's challenges and to keep up with the changes in its environment, but also that it can actas a forerunner by creating innovations, both at the tactical and strategic levels of operation and thereby change the rules of the market. However, even though it is widely agreed that the dynamic capability for continuous learning, development and renewal is a major source of competitive advantage, there is no widely shared view on how organizational renewal capability should be defined, and the field is characterized by a plethora of concepts and definitions. Furthermore,there is a lack of methods for systematically assessing organizational renewal capability. The dissertation aims to bridge these gaps in the existing research by constructing an integrative theoretical framework for organizational renewal capability and by presenting a method for modeling and measuring this capability. The viability of the measurement tool is demonstrated in several contexts, andthe framework is also applied to assess renewal in inter-organizational networks. In this dissertation, organizational renewal capability is examined by drawing on three complimentary theoretical perspectives: knowledge management, strategic management and intellectual capital. The knowledge management perspective considers knowledge as inherently social and activity-based, and focuses on the organizational processes associated with its application and development. Within this framework, organizational renewal capability is understood as the capacity for flexible knowledge integration and creation. The strategic management perspective, on the other hand, approaches knowledge in organizations from the standpoint of its implications for the creation of competitive advantage. In this approach, organizational renewal is framed as the dynamic capability of firms. The intellectual capital perspective is focused on exploring how intangible assets can be measured, reported and communicated. From this vantage point, renewal capability is comprehended as the dynamic dimension of intellectual capital, which consists of the capability to maintain, modify and create knowledge assets. Each of the perspectives significantly contributes to the understanding of organizationalrenewal capability, and the integrative approach presented in this dissertationcontributes to the individual perspectives as well as to the understanding of organizational renewal capability as a whole.
