Researchers recommend a reorganization of the medical profession into larger groups with a multispecialty mix. We analyze whether there is evidence for the superiority of these models and if this organizational transformation is underway.

We summarize the evidence on scale and scope economies in physician group practice, and then review the trends in physician group size and specialty mix to conduct survivorship tests of the most efficient models.

The distribution of physician groups exhibits two interesting tails. In the lower tail, a large percentage of physicians continue to practice in small, physician-owned practices. In the upper tail, there is a small but rapidly growing percentage of large groups that have been organized primarily by non-physician owners.

While our analysis includes no original data, it does collate all known surveys of physician practice characteristics and group practice formation to provide a consistent picture of physician organization.

Our review suggests that scale and scope economies in physician practice are limited. This may explain why most physicians have retained their small practices.

Larger, multispecialty groups have been primarily organized by non-physician owners in vertically integrated arrangements. There is little evidence supporting the efficiencies of such models and some concern they may pose anticompetitive threats.

This is the first comprehensive review of the scale and scope economies of physician practice in nearly two decades. The research results do not appear to have changed much; nor has much changed in physician practice organization.

Studies have identified low levels of social support as one of several risk factors for poor psychological outcome following bereavement. Despite this fact, little is known about how bereaved individuals interpret and define social support or which behaviors they perceive as helpful (Cacciatore, Thieleman, Fretts, & Jackson, 2021). The present study seeks to understand the experiences of the support received by Danish families who have lost a parent to death. Individuals recruited from a mutual bereavement support group (N = 87, 25–59 years old) responded to an online survey, which yielded both quantitative and qualitative data, the latter from open-ended questions and comment boxes. The results demonstrated a variety of sources of support. However, some of the bereaved individuals also reported a decided lack of help for both adults and children post-loss. As most respondents were women (93%), future research might shed more light on possible gender differences in the expectations, needs, and experiences of social support in bereavement. The study participants provided elaborate suggestions for the improvement of bereavement support, such as, practical help, access to bereavement support groups, more knowledge on bereavement and grief in the Danish society, and easier access to peer support. The chapter revealed an apparent lack of coordination of the support for parentally bereaved families. Additionally, some groups of bereaved children seemed to be particularly vulnerable and overlooked, namely the very young children, children in late adolescence/young adulthood, and children with special needs.

Purpose – The chapter explores the methodological challenges in doing community-based participatory research (CBPR) in social science investigations with immigrant women experiencing intimate partner violence (IPV) in Canada.

Methodology/approach – The methodological comments, observations, and challenges discussed in this chapter result from research funded by the Social Science and Humanities Council, a branch of the Canadian Federal Tri-Council. The research that the authors conducted was both quantitative and qualitative in nature. The sample consisted of three groups of women: (1) immigrant women in Canada >10 years, (2) immigrant women in Canada <10 years, and (3) visible minority women born in Canada.

Findings – The chapter highlights some of the lessons learned in conducting CBPR research in the context of immigrant survivors of IPV. This discussion can be relevant to both academics and non-profit/advocacy agencies interested in pursuing community partnership research on interpersonal violence.

Originality/value – There is a paucity of writings on CBPR research in the social science and the challenges. This chapter reveals the methodological challenges that the researchers experienced in doing CBPR with racialized immigrant women who are survivors of IPV. This discussion can be relevant to both academics and non-profit/advocacy agencies interested in pursuing community partnership research on interpersonal violence.

To meet an increased production demand and to speed the development of an entirely new range of products, Marconi Avionics Limited is opening a newly‐equipped Hydraulics Facility at its Airport Works factory, Rochester, England. The facility, which is being formally opened today by Mr. C. R. Robinson, Editor of the magazine “Design Engineering”, has the skilled staff and equipment needed to compete more effectively in world markets.
