HG 326.65-326.75

Dark brown sediment with clasts ranging from small to large. Grains are sub-angular in shape. Faint water escape structures are present.

HG 354.65-354.75

Grey sediment with clasts ranging from small to medium in size. Clasts are sub-angular to sub-rounded. Rotation structures can be seen throughout. Some clasts have multiple rotation structures surrounding them. Comet structures and lineations are also present.

HG 450.65-450.75

Mainly a coarse brown sediment with a few patches of a finer grained domain. The clasts range from small to large in size and angular to sub-rounded in clast shape. The coarser domain mainly contains grain crushing and stacking, with some rotation structures. The finer domain mainly contains lineations.

HG 484.65-484.80

Brown sediment with multiple domains. Grains range from small to large in size, and angular to sub-rounded in shape. Large amounts of grain crushing can be seen in the coarser domains. The sample is mainly dominated with grain crushing. The finer grained domains contain some clay rich material. Some lineations and rotation structures can also be seen throughout the different domains.

HG 69.45-69.65

Dark brown sediment with clasts ranging from small to medium in size. The clast shape ranges from angular to sub-rounded. Lineations are abundant throughout the sample. Comet structures and grain crushing/stacking are also present in minor amounts.

HG 77.55-77.65

Brown sediment with clasts ranging from small to medium. The majority of the clasts are medium sized. Clasts range from sub-angular to sub-rounded in shape. Lineations are common in this sample along with edge-to-edge grain crushing. Comet structures can also be seen in minor amounts.

HG 82.50-82.65

Dark brown sediment with well dispersed clasts ranging from small to medium in size. Clast shape ranges from sub-angular to sub-rounded. Lineations can commonly be seen throughout the sample. Comet structures can also be seen in minor amounts.

HG 125.65-125.75

Brown sediment with clasts ranging from small to large in size. The clast shape ranges from angular to rounded. Rotation structures are abundant in this sample along with lineations. Comet structures and grain crushing is also present throughout this sample.

HG 129.65-129.75

Brown sediment with two main domains; a fine grained one rich in organic material and a coarse grained domain. The fine grained domain appears in several areas of the sample, and in one area alternates with the coarser domain. The coarse grained domain contains clasts ranging from small to medium in size, and angular to sub-rounded in shape. Grain crushing and lineations can commonly be seen in this domain.

HG 154.65-154.75

Coarse grained sediment with clasts ranging from small to medium in size. Clast shape ranges from angular to rounded. Rotation structures can commonly be seen throughout this sample. Edge-to-edge grain crushing with a few lineations can also be seen throughout the sample.

HG 182.65-182.75

Light brown sediment with clasts ranging from small to medium in size. The clast shape ranges from sub-angular to sub-rounded. Rotation structures can commonly be seen, along with some comet structures as well. A few lineations and edge-to-edge grain crushing can also be observed. There is also the inclusion of a fine grained domain that is a darker brown (tanned-brown).

HG 182.65-182.75A

Light brown sediment with clasts ranging from small to medium in size. Clast shape ranges from angular to sub-rounded. Rotation structures are abundant throughout the sample. Comet structures and lineations can also be seen.

HG 183.65-183.75

Brown sediment with clasts ranging from small to large. Clast shape ranges from sub-angular to rounded. Rotation structures and necking structures are abundant throughout the sample. A few lineations can also be seen.

Comparaisons de projections des niveaux d'incapacité de la population canadienne de 65 ans et plus en 2031

Le vieillissement de la population canadienne prévisible dans les prochaines années entrainera d’importants changements au point de vue social. L’un d’eux est l’augmentation fulgurante du nombre d’aînés en état d’incapacité. Utilisant le modèle de microsimulation LifePaths, cette recherche compare deux projections, ayant des méthodologies différentes, du nombre d’individus en incapacité de 65 ans et plus vivant en ménage privé en 2031. La première méthode utilise le module d’incapacité de LifePaths pour générer les individus en incapacité tandis que la seconde méthode utilise plutôt une régression logistique ordonnée pour les obtenir. Les projections du nombre d’individus en état d’incapacité des deux méthodes nous permettent une comparaison entre ces résultats. Suite à l’élaboration de tableaux et de graphiques permettant de tracer un portait de la situation, cette recherche essaie de démystifier les sources possibles à l’origine de ces différences. Les résultats montrent d’importantes différences entre les projections, spécifiquement pour les individus en état d’incapacité sévère. De plus, lorsqu’on s’intéresse aux variables d’intérêts, on remarque que les différences de projections d’effectifs sont importantes chez les hommes et les gens mariés. Par contre, lorsque les proportions sont analysées, c’est plutôt le groupe d’âges 80 ans et plus ainsi que les projections pour la province du Québec qui créent problème. Ces différences sont attribuables aux caractéristiques d’un modèle de microsimulation, aux populations de départ ainsi qu’aux paramètres définis. Les résultats démontrés dans cette recherche mettent en garde sur les travaux étudiant le nombre d’individus en incapacité dans le futur. Nos deux méthodes ayant des résultats différents, nous ne pouvons pas conclure avec certitude quelle sera la situation dans le futur.
