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.

Transcript [original spelling and grammar retained]: Albany June 28 1812 Sir Your letter of the 23d has been received. I had anticipated your request by ordering the detachment from Washington, Essex, Clinton and Franklin Counties into service and have fixed the days and places of their Rendezvous. Upon application to the quarter master General I find there are but 139 tents & 60 camp kettles at this place & even those I take by a kind of stealth. The Deputy Quarter Master General declines giving an order for their delivery until he shall have a written order from the Quarter Master General, and the latter is willing I Shall take them but will not give the Deputy a written order for that purpose. Under Such circumstances I shall avail myself of the rule of Possession and by virtue of the Eleven Points of Law Send them tomorrow morning without a written order from anyone. You may remember that when you were Secretary of the war department I invited you to forward and deposit in our Frontier Arsenals, arms ammunition and camp equipage free of expense to be ready in case of war and the same invitation to the war department has been repeated some time, Since The United States have now from 5 to 600 regular troops at Plattsburgh, Rome, Canandaigua & c, where those arsenals are, and yet those recruits are now and must be for weeks to come unarmed and unequipped in every respect although within musket Shot of arsenals. The recruits at Plattsburgh are within 50 miles of two tribes of Canadian Indians. In case of an attack upon the Frontiers that portion of the United States army would be as inefficient and unable to defend the inhabitants or themselves even. The Militia Detachments on the Western Frontiers received the news of war with [cherafulness] and determined courage, and I am happy to find they are united late brothers, highly improved in Discipline & ready to devote themselves to any Service or danger which the good of the Country may require. But they are in barracks from which they cannot move a days march for the want of tents and other equipage, and they are in Separate and Independent Detachments without a General Officer to command them or combine their exertions for the accomplishment of any desirable and important object. The only officer of the United States here who can do anything is the Quarter Master General and he has not a tent Camp Kettle or Knapsack in this arsenal except what I have concluded to send off tomorrow morning as above mentioned to furnish men As to Cannon Muskets and Ammunition. I can find now one here who will exercise any authority over them or deliver a Single article upon my requisition. Neither can I find any Officer of the army who feel himself authorized to exercise any authority or do any act which will aid me in the all important object of protecting the Inhabitants of an extended Frontier exposed to the Cruelties of Savages and the depredations of the enemy. If I must rely upon the Militia Solely for Such protection I entreat you to give orders to your Officers to furnish upon my orders, for the use of the Militia Detachments , all needful weapons and articles with which the United States are Supplied and of which we are destitute . You may rely upon all the assistance which my talents, influence or authority can furnish in the active prosecution of the first & necessary way which has been declared by the Constituted Authorities of our beloved Country. I am, Sir, respectfully Your ob. Servt. Daniel D. Tompkins

This thesis examines the performance of Canadian fixed-income mutual funds in the context of an unobservable market factor that affects mutual fund returns. We use various selection and timing models augmented with univariate and multivariate regime-switching structures. These models assume a joint distribution of an unobservable latent variable and fund returns. The fund sample comprises six Canadian value-weighted portfolios with different investing objectives from 1980 to 2011. These are the Canadian fixed-income funds, the Canadian inflation protected fixed-income funds, the Canadian long-term fixed-income funds, the Canadian money market funds, the Canadian short-term fixed-income funds and the high yield fixed-income funds. We find strong evidence that more than one state variable is necessary to explain the dynamics of the returns on Canadian fixed-income funds. For instance, Canadian fixed-income funds clearly show that there are two regimes that can be identified with a turning point during the mid-eighties. This structural break corresponds to an increase in the Canadian bond index from its low values in the early 1980s to its current high values. Other fixed-income funds results show latent state variables that mimic the behaviour of the general economic activity. Generally, we report that Canadian bond fund alphas are negative. In other words, fund managers do not add value through their selection abilities. We find evidence that Canadian fixed-income fund portfolio managers are successful market timers who shift portfolio weights between risky and riskless financial assets according to expected market conditions. Conversely, Canadian inflation protected funds, Canadian long-term fixed-income funds and Canadian money market funds have no market timing ability. We conclude that these managers generally do not have positive performance by actively managing their portfolios. We also report that the Canadian fixed-income fund portfolios perform asymmetrically under different economic regimes. In particular, these portfolio managers demonstrate poorer selection skills during recessions. Finally, we demonstrate that the multivariate regime-switching model is superior to univariate models given the dynamic market conditions and the correlation between fund portfolios.

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.

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.

Ouvrant la réflexion sur les enjeux de la perte massive de la biodiversité, l'article s'appuie sur la question élémentaire de l'importance de la diversité biologique pour l'homme, à la fois sur le plan économique, biologique et éthique. La maîtrise de la nature par l'homme se révèle être une illusion. La réalité étant celle de l'interaction, il est permis de dire que les sociétés humaines agissent sur leurs propres conditions en modifiant les équilibres biologiques pour satisfaire leurs besoins, sans pour autant intégrer cette interaction fondamentale dans l'équation d'un rapport viable entre l'homme et la nature. L'approche récente par le biais des analyses des services écologiques constitue à cet égard un progrès sensible. Il aboutit néanmoins au constat de l'impossibilité pour l'humanité de se substituer aux mécanismes naturels permettant de tirer les services de la nature nécessaires à sa survie. Plutôt que de prétendre contrôler et maîtriser la nature à tout prix, l’homme devrait apprendre à se reconnaître comme une partie consciente de la nature et à vivre avec la vie qui l’entoure. Cet apprentissage soulève des défis scientifiques, humains et de gouvernance. L'article prône la nécessité d'une science de la biodiversité intégrée et non plus éclatée, condition essentielle pour l'élaboration de politiques économiques et sociales qui intègrent la viabilité de l'utilisation des ressources naturelles et des services qu'elles procurent.
