Noting the increasing numbers of grandparents who have taken on the role of parenting their grandchildren, short- or long-term, this manual addresses the themes and problems that are the most central ...to grandparents who are raising grandchildren, including drastic life changes, parenting issues, frustration, and legal problems. The book is divided into three sections. Section 1, "When the Second Shift Arrives," covers the personal and social aspects of raising grandchildren: the changes, the feelings, and the problems of adult children, grandchildren, and family in general in these circumstances. The section starts with an overview of the recent rise in grandparents as parents and looks at some of the myths about the phenomenon. Section 2, "Through the Red Tape, " addresses the bureaucratic part of raising grandchildren, the legal issues, and the availability of government assistance and special education. Section 3, "Strength in Numbers," focuses on the larger community of grandparents as parents and provides information on finding and starting support groups as well as on the political aspects of the grandparent movement. The appendices include a list of resources for grandparents and relative caregivers, conversation topics that should be addressed by grandparents and support groups, and finally information on specific grandparents whose stories are mentioned in the book. Contains 136 references. (AA)
Bio-based materials, such as wood bio-concrete (WBC), hold promise in reducing energy consumption and carbon footprint of the construction industry. However, the durability of these materials is not ...well understood and can be negatively affected by the high water absorption capacity of wood bio-aggregates. In the field of cement composites, for example, silane–siloxane-based water repellent has been used to protect such materials from natural environmental attack. Nevertheless, there is still a limited understanding of various aspects related to this type of treatment, including its performance when applied to the bio-concrete substrate. This research aimed to investigate the influence of silane–siloxane on the rheology and hydration of cementitious paste through isothermal calorimetry and thermogravimetric analysis. Additionally, the impact of silane–siloxane on the physical and mechanical properties of WBCs was examined by conducting tests at fresh state (flow table and entrained air content) and hardened state (compressive strength and capillary water absorption). The composites were produced with a volumetric fraction of 45% of wood shavings while the cement matrix consisted of a combination of cement, rice husk ash, and fly ash. Silane–siloxane was applied in three ways: as coating, incorporated as an admixture, and in a combination of both methods. The results indicated that by incorporating silane in the cementitious pastethe viscosity increased by 40% and the hydration was delayed by approximately 6 h when compared to the reference. In addition, silane improved the compressive strength of WBCs by 24% when incorporated into the mixture, expressively reduced the water sorptivity of WBCs (93%), and was more effective if used as coating.
While attention on logging in the tropics has been increasing, studies on the long‐term effects of silviculture on forest dynamics and ecology remain scare and spatially limited. Indeed, most of our ...knowledge on tropical forests arises from studies carried out in undisturbed tropical forests. This bias is problematic given that logged and disturbed tropical forests are now covering a larger area than the so‐called primary forests. A new network of permanent sample plots in logged forests, the Tropical managed Forests Observatory (TmFO), aims to fill this gap by providing unprecedented opportunities to examine long‐term data on the resilience of logged tropical forests at regional and global scales. TmFO currently includes 24 experimental sites distributed across three tropical regions, with a total of 490 permanent plots and 921 ha of forest inventories.

Ce recueil est un hommage à Antonio Lozano, romancier, dramaturge et traducteur, disparu en 2019, très sensible au problème des migrants et qui en fait les protagonistes de plusieurs de ses ...fictions. Les différents textes proposés réfléchissent aux modes de fictionnalisation de l’exil dans le théâtre et le roman contemporains et aussi au témoignage qu’apportent la photographie et le cinéma documentaire. Le premier axe de réflexion est celui de l’absence générée par le départ des émigrants ou des populations déplacées. Puis nous nous intéressons aux manifestations de l’altérité, qui engendre opposition, refus ou acceptation et fusion culturelle. Enfin le dernier axe de réflexion porte sur les éclatements et fusions que supposent l’émigration et l’adaptation à un nouvel environnement. Este volumen es un homenaje a Antonio Lozano, novelista, dramaturgo y traductor, fallecido en 2019, muy atento a la cuestión de las migraciones actuales y a las dramáticas condiciones en que se producen. Hizo de los migrantes los protagonistas de varias de sus ficciones. Los distintos textos propuestos reflexionan sobre las distintas modalidades de ficcionalización del exilio, el éxodo y los movimientos migratorios actuales en el teatro y la novela contemporáneos, pero también sobre los testimonios que ofrecen la fotografía y el cine documental. El primer eje de reflexión se centra en la ausencia que genera la partida. La segunda se centra en las manifestaciones de la alteridad: oposición, rechazo o aceptación y fusión cultural. Finalmente, el último eje trata de las escisiones y fusiones que conllevan la emigración y la adaptación a un nuevo entorno.
