There is substantial research linking meaning-making ability and psychological well-being in the context of turning point events. Still, an important research question remains: whether individuals who report meaning-making and psychological well-being were already better adjusted psychologically, prior to the experience of their turning point. In addition, the role of meaning-making on academic achievement and parental relationship quality has received little empirical attention although both variables have been shown to be positively associated with positive adjustment among adolescents. This longitudinal study examined differences in psychological well-being, academic achievement, and parental relationship quality between adolescents who reported meaning-making (lessons or insights) and those who reported no meaning-making within their turning point narratives. Participants were 803 (52% female) grade 12 adolescents, 26% (N = 209) of whom had reported experiencing a turning point. Participants also completed measures on the outcome variables (psychological well-being, academic achievement, and parental relationship quality) 3 years prior, when they were in grade 9. MANOVA results indicated that, of the participants who experienced a turning point, adolescents who reported meaning-making reported significantly higher psychological wellbeing and more positive parental relationship quality than adolescents who reported no meaningmaking. Importantly, these two groups did not differ on the outcome variables prior to their experience of a turning point event when they were in grade 9. Academic achievement scores did not differ significantly between adolescents who reported meaning-making and those who reported no meaning-making. These findings highlight the importance of meaning-making in relation to positive adjustment subsequent to a turning point among adolescents.

Par contraste avec de nombreux pays européens qui ont clarifié leur position vis-à-vis la génétique et l’assurance vie, le Canada en est encore à établir la sienne. Toute initiative en ce domaine doit être basée sur une compréhension des mécanismes de l’assurance vie, de la nature de l’information génétique, de l’historique du débat au sujet de la génétique et de l’assurance vie au Canada et, finalement, des raisons pour lesquelles un groupe de travail canadien a décidé de relever le défi.

In this paper, we develop finite-sample inference procedures for stationary and nonstationary autoregressive (AR) models. The method is based on special properties of Markov processes and a split-sample technique. The results on Markovian processes (intercalary independence and truncation) only require the existence of conditional densities. They are proved for possibly nonstationary and/or non-Gaussian multivariate Markov processes. In the context of a linear regression model with AR(1) errors, we show how these results can be used to simplify the distributional properties of the model by conditioning a subset of the data on the remaining observations. This transformation leads to a new model which has the form of a two-sided autoregression to which standard classical linear regression inference techniques can be applied. We show how to derive tests and confidence sets for the mean and/or autoregressive parameters of the model. We also develop a test on the order of an autoregression. We show that a combination of subsample-based inferences can improve the performance of the procedure. An application to U.S. domestic investment data illustrates the method.

We propose an alternate parameterization of stationary regular finite-state Markov chains, and a decomposition of the parameter into time reversible and time irreversible parts. We demonstrate some useful properties of the decomposition, and propose an index for a certain type of time irreversibility. Two empirical examples illustrate the use of the proposed parameter, decomposition and index. One involves observed states; the other, latent states.

Le développement durable a pour objectif de concilier des exigences diverses,sinon antagoniques :l’économique, le social,l’environnemental.On peut donc se demander s’il répond vraiment aux intuitions qui sont au point de départ de la conscience écologique. Nous en dégageons trois, dans trois domaines : l’exigence de protection de la nature, la conviction que la solution à la crise environnementale ne peut pas être purement technique, et l’insistance sur la dimension sociale, et pas seulement naturelle, de la crise environnementale. Chacune de ces exigences donne lieu à des débats conflictuels : préservation contre conservation,souci éthique contre optimisme technologique,exigence sociale et politique contre traitement scientiste des questions environnementales. De l’examen de ces litiges,il ressort que l’avenir du développement durable passe par une reformulation du concept de nature.
