Comparing motives, goals and weight training behaviours of competitive and recreational weight trainers: An application of organismic integration theory and goal contents theory

The study purpose was to examine differences between competitive and recreational weight trainers on indices of motivation, goals and behaviour. Data was collected from a purposive sample of competitive (n = 177; Mage = 30.86; SDage = 11.35) and recreational (n = 196; Mage = 21.97; SDage = 6.05) weight trainers using a cross-sectional, non-experimental design. Participants completed the Behavioural Regulation in Exercise Questionnaire-2R, Exercise Motivations Inventory-2, assessment of weight training behaviour and demographic questions. Multivariate analyses of variance indicated higher endorsement of autonomous motives and mostly intrinsically-oriented goals, while independent samples t-tests indicated higher frequency of weight training behaviour among the competitive weight trainers. Group differences were independent of demographic factors. Findings suggest that autonomous motives and intrinsic goals may not be undermined by competition among competitive weight trainers. This study also provides support for the utility of organismic integration theory and goal contents theory in examining strength-based exercise.

Adult Learning in the Transformational Environments of the Digital Revolution: Connecting Theory and Practice

The purpose of this study was to investigate the learning preferences and the post-secondary educational experiences of a group of Net-Gen adult learners, aged between 18 and 35, currently working in the knowledge economy workplace, and their assessment of how adequately they were prepared to meet the requirements of the knowledge economy workplace. This study utilized an explanatory mixed-method research design. Participants completed a questionnaire providing information on their self-reported learning style preferences, their use of digital tools for formal and informal learning, their use of digital technologies in postsecondary educational experiences, and their use of digital technologies in their workplace. Four volunteers from the questionnaire respondents were selected to participate in interviews based on the diversity of their experiences in higher education, including digital environments, and the diversity of their knowledge economy workplaces. Data collected from the questionnaire were analyzed for descriptive and demographic statistics, and categorized so that common patterns could be identified from information gathered from the online questionnaire and interviews. Findings based on this study indicated that these Net-Gen adult learners were fluent with all types of digital technologies in collaborative environments, expecting their educational experiences to provide a similar experience. Participants clearly expressed an understanding that digital/collaborative aptitudes are essential to successful employment in the knowledge economy workplace. The findings of this study indicated that the majority of participants felt that their post-secondary educational experiences did not adequately prepare them to meet the expectations of this type of working environment.

An Abstract Algebraic Theory of L-Fuzzy Relations for Relational Databases

Classical relational databases lack proper ways to manage certain real-world situations including imprecise or uncertain data. Fuzzy databases overcome this limitation by allowing each entry in the table to be a fuzzy set where each element of the corresponding domain is assigned a membership degree from the real interval [0…1]. But this fuzzy mechanism becomes inappropriate in modelling scenarios where data might be incomparable. Therefore, we become interested in further generalization of fuzzy database into L-fuzzy database. In such a database, the characteristic function for a fuzzy set maps to an arbitrary complete Brouwerian lattice L. From the query language perspectives, the language of fuzzy database, FSQL extends the regular Structured Query Language (SQL) by adding fuzzy specific constructions. In addition to that, L-fuzzy query language LFSQL introduces appropriate linguistic operations to define and manipulate inexact data in an L-fuzzy database. This research mainly focuses on defining the semantics of LFSQL. However, it requires an abstract algebraic theory which can be used to prove all the properties of, and operations on, L-fuzzy relations. In our study, we show that the theory of arrow categories forms a suitable framework for that. Therefore, we define the semantics of LFSQL in the abstract notion of an arrow category. In addition, we implement the operations of L-fuzzy relations in Haskell and develop a parser that translates algebraic expressions into our implementation.

Innis Lecture: Can the Theory of Incentives Explain Decentralization?

This survey presents within a single model three theories of decentralization of decision-making within organizations based on private information and incentives. Renegotiation, collusion, and limits on communication are three sufficient conditions for decentralization to be optimal.

Some Additional Specification Tests for Generalized Method of Moments Estimators with Macro-Economic Applications Part I : Theory

In This Paper Several Additional Gmm Specification Tests Are Studied. a First Test Is a Chow-Type Test for Structural Parameter Stability of Gmm Estimates. the Test Is Inspired by the Fact That \"Taste and Technology\" Parameters Are Uncovered. the Second Set of Specification Tests Are Var Encompassing Tests. It Is Assumed That the Dgp Has a Finite Var Representation. the Moment Restrictions Which Are Suggested by Economic Theory and Exploited in the Gmm Procedure Represent One Possible Characterization of the Dgp. the Var Is a Different But Compatible Characterization of the Same Dgp. the Idea of the Var Encompassing Tests Is to Compare Parameter Estimates of the Euler Conditions and Var Representations of the Dgp Obtained Separately with Parameter Estimates of the Euler Conditions and Var Representations Obtained Jointly. There Are Several Ways to Construct Joint Systems Which Are Discussed in the Paper. Several Applications Are Also Discussed.

A Theory of Random Consumer Demand

This paper presents a new theory of random consumer demand. The primitive is a collection of probability distributions, rather than a binary preference. Various assumptions constrain these distributions, including analogues of common assumptions about preferences such as transitivity, monotonicity and convexity. Two results establish a complete representation of theoretically consistent random demand. The purpose of this theory of random consumer demand is application to empirical consumer demand problems. To this end, the theory has several desirable properties. It is intrinsically stochastic, so the econometrician can apply it directly without adding extrinsic randomness in the form of residuals. Random demand is parsimoniously represented by a single function on the consumption set. Finally, we have a practical method for statistical inference based on the theory, described in McCausland (2004), a companion paper.

Bayesian Analysis for a Theory of Random Consumer Demand: The Case of Indivisible Goods

McCausland (2004a) describes a new theory of random consumer demand. Theoretically consistent random demand can be represented by a \"regular\" \"L-utility\" function on the consumption set X. The present paper is about Bayesian inference for regular L-utility functions. We express prior and posterior uncertainty in terms of distributions over the indefinite-dimensional parameter set of a flexible functional form. We propose a class of proper priors on the parameter set. The priors are flexible, in the sense that they put positive probability in the neighborhood of any L-utility function that is regular on a large subset bar(X) of X; and regular, in the sense that they assign zero probability to the set of L-utility functions that are irregular on bar(X). We propose methods of Bayesian inference for an environment with indivisible goods, leaving the more difficult case of indefinitely divisible goods for another paper. We analyse individual choice data from a consumer experiment described in Harbaugh et al. (2001).

La transformation du rôle de représentante d’aidantes familiales pendant l’hébergement de leur parent atteint de démence : une théorisation ancrée

RÉSUMÉ L‘hébergement en centre de soins de longue durée d'un parent âgé atteint de démence marque une transition pour les personnes qui occupent un rôle d’aidant familial principal. Ces personnes, principalement des femmes, poursuivent leur engagement après l’hébergement et souhaitent être impliquées dans les décisions concernant les soins offerts à leur parent. Souvent l'hébergement survient au moment où la personne âgée n'est plus en mesure, compte tenu de ses déficiences cognitives, d'exprimer clairement ses besoins; les aidantes accordent alors une place centrale au rôle de représentante de leur proche hébergé. Cette étude avait pour but d’expliquer la transformation du rôle de représentante chez des aidantes familiales dont le parent atteint de démence vit dans un centre d’hébergement et de soins de longue durée (CHSLD). La méthode qualitative de la théorisation ancrée a été retenue pour expliquer ce processus social. Les résultats obtenus reposent sur 14 entrevues en profondeur réalisées auprès de filles dont le parent atteint de démence était hébergé depuis plus de six mois dans un CHSLD. Ces aidantes ont été sélectionnées selon une procédure d’échantillonnage théorique et l’analyse des données a été réalisée à partir de la transcription intégrale des entrevues en suivant trois niveaux d'analyse, soit la codification ouverte, axiale et sélective. Une proposition théorique, générée par voie inductive, met en lumière trois processus intermédiaires interreliés expliquant la transformation du rôle de représentante pendant l’hébergement du proche : 1) l’intégration dans le milieu ; 2) l’évaluation de la qualité des soins et 3) le développement de la confiance envers le milieu d’hébergement. Plus précisément, les aidantes déploient différentes stratégies d’intégration dans le milieu d’hébergement, soit l’établissement de relations de réciprocité et d’une collaboration avec le personnel soignant, ainsi que l’utilisation d’un style de communication diplomatique. Parallèlement, elles évaluent la qualité des soins en trois étapes : jugement, pondération et action. Finalement, une relation de confiance avec les membres du personnel de l’établissement se développe en lien avec cinq facteurs spécifiques, soit les premières impressions, la comparaison avec d’autres CHSLD, l’intérêt démontré par le personnel envers le proche, le fait d’être entendue et prise au sérieux et la transparence du milieu d’hébergement. Ces trois processus contribuent au bien-être du parent hébergé et à celui de l’aidante. Le développement de la confiance étant associé aux deux autres processus intermédiaires ainsi qu’au bien-être de l’aidante, il est le processus central de la théorie contextuelle qui émerge de cette recherche. Cette étude contribue au développement des connaissances, notamment en fournissant plusieurs éléments inédits de compréhension du processus de transformation du rôle de représentante des aidantes familiales, de même que des pistes pour soutenir ces aidantes dont le parent, souffrant de démence, n’est plus en mesure de prendre des décisions. La théorie contextuelle proposée dans le cadre de cette étude constitue les prémices d’une théorie de niveau intermédiaire portant sur le rôle de représentant des aidants familiaux dans le contexte plus général du système de santé. Des études réalisées dans d’autres contextes de soins et auprès d’aidants de proches vulnérables ayant d’autres types d’affections sont ainsi recommandées.
