PurposeCanada's population is aging and there are concerns that the welfare system may not support the increased demands on it. Integrated health and social care (IHSC) produces positive health and system outcomes but it needs to be better understood within a Canadian context. The purpose of this collective case study of three IHSC initiatives in Alberta, Ontario and Nova Scotia was to determine the factors that support successful services integration among different healthcare and social services organizations serving older adults within a Canadian context.Design/methodology/approachThis study used the Cheng and Catallo (2020) IHSC conceptual framework (CF) to guide the research. Primary data were based on key informant interviews of representatives from organizations that comprised each case and focus groups. A cross-case analysis was undertaken to determine common themes.FindingsThe cross-case analysis revealed that the three cases shared common integration and external influence factors based on the Cheng and Catallo (2020) CF. Some new factors were identified.Originality/valueThe study revealed that the Canadian context was important in influencing integration in the three cases and that there is a unique Canadian aspect to IHSC. The study offers up practical insights for government leaders and service administrators to improve IHSC for older adults. The study also identifies how the Cheng and Catallo (2020) IHSC CF can be enhanced and points to research opportunities to test the framework.

ABSTRACT In the trailing gases of fuel cells, there are small quantities of CO, and the water-gas shift reaction is the method which is applies recently to remove large amount of CO in the trailing gases. This research is to develop, Cu-series catalysts with high performance of removing CO at low temperatures (200 ℃-280 ℃). In this research, silicon dioxide (SiO2) and titanium dioxide (TiO2) were used as carries, and Cu was used as active method; first, active metals of different proportions were impregnated on carries, then they were calcined at the high temperature of 500 ℃. After being reduced, the catalysts possessed the best efficiency of removing CO. The characteristic analyses of the Cu-series catalysts were performed by TGA, TPR, TPO, XRD, ICP and SEM. The water-gas shift reaction was carried out in the fixed-bed reaction: under the circumstances of the hydrogen-rich atmosphere, a gas containing small quantity of CO for simulating the trailing gas of fuel cell passed through the reactor, and before the reaction took place, the catalysts were reduced with hydrogen; besides, comparisons of the active metals of oxidization state with the active metals of reduction state were made, so as to find out the differences in efficiencies of removing CO and the optimal proportions of catalysts. The experimental results showed that active metals on SiO2 carriers possessed the best dispersions and Cu surface areas, and the particle diameters of active metals obtained were small. From the reduction peak diagrams of TPR, it could be known that the higher was the active metals content in the catalyst, the easier was on the carrier surface to from large grains of oxidized copper, and the higher was the reduction temperature, showing that when the catalysts carried out WGSR, the activities were poorer. During WGSR, it could be found that whether the carries was SiO2 or TiO2, Cu of the reduced state possessed better CO removing power than Cu of the oxidized state; for the catalysts with SiO2 as the carrier, when the Cu content researched to 35 wt%, the CO removing percentage at 250 ℃ could reach 90%; whereas, for the catalysts with TiO2 as the carrier, when the Cu content reached to 30 wt%, the CO removing percentage at 300 ℃ could reach 75%.

El estudio de los procedimientos que posibilitan la salida de las víctimas de la violencia sigue siendo de actualidad. Por lo tanto, en este documento, se analizan los procesos involucrados para poner fin a la violencia. Ya en la década de 1970, tanto la violencia hacia las mujeres como la violencia practicada por la pareja íntima se reconocieron a modo de problemas sociales reales y se convirtieron en temas centrales de la agenda política europea, situación que fue tomada como prioritaria gracias a los movimientos feministas. Desde entonces, estudiar la violencia ha sido todo un desafío. En 1997, la violencia doméstica se convirtió en tema de atención pública en Bélgica cuando la ley introdujo la noción de delito grave en el caso de agresiones intencionales contra un cónyuge o excónyuge. En 2006, la posición de Bélgica contra la violencia doméstica se fortaleció con la adopción de la política de cero tolerancias (Melan, 2017). A partir de estas leyes, las investigaciones acerca de las víctimas que abandonan relaciones violentas han ido en aumento (Hendy et al., 2003; Offermans y Kacenekenbogen, 2010; Catallo et al., 2013) y es notorio que los estudios se enfocan casi exclusivamente en mujeres víctimas. Los estudios sobre hombres maltratados y sus trayectorias siguen siendo escasos (Jaillet y Vanneste, 2017).
