Teaching Family Systems Theory: A Developmental-Constructivist Perspective

Kegan’s (1994) “In Over Our Heads” phenomenon has much to offer those who engage in teaching family systems theory and therapy, particularly in relationship to the tensions involved in the potential mismatch between the developmental demands of the curriculum and orders of consciousness which characterize students’ responses to the material. One useful way to think about teaching in ways that address the phenomenon that Kegan has named is David Kolb’s (1984) theory of experiential learning. Specific applications of this theory to teaching family systems theory are presented, as well issues involved in professional development based on the challenge this Kegan and Kolb developmental-constructivist perspective brings to department or program culture in which a family systems theory curriculum operates

Systematic review and meta-analysis of clinical trials examining the effect of hyperbaric oxygen therapy in people with diabetes-related lower limb ulcers

Aim: To examine the efficacy of hyperbaric oxygen therapy in healing diabetes-related lower limb ulcers through a meta-analysis of randomized clinical trials. Methods: A literature search was conducted to identify appropriate clinical trials. Inclusion required randomized study design and reporting of the proportion of diabetes-related lower limb ulcers that healed. A meta-analysis was performed to examine the effect of hyperbaric oxygen therapy on ulcer healing. The secondary outcomes were minor and major amputations. Results: Nine randomized trials involving 585 participants were included. People allocated to hyperbaric oxygen therapy were more likely to have complete ulcer healing (relative risk 1.95, 95% CI 1.51–2.52; P<0.001), and less likely to require major (relative risk 0.54, 95% CI 0.36–0.81; P=0.003) or minor (relative risk 0.68, 95% CI 0.48–0.98; P=0.040) amputations than control groups. Sensitivity analyses suggested the findings were dependent on the inclusion of one trial. Adverse events included ear barotrauma and a seizure. Many of the trials were noted to have methodological weaknesses including absence of blinding of outcome assessors, lack of a justifiable sample size calculation and limited follow-up. Conclusions: This meta-analysis suggests hyperbaric oxygen therapy improves the healing of diabetes-related lower limb ulcers and reduces the requirement for amputation. Confidence in these results is limited by significant design weaknesses of previous trials and inconsistent findings. A more rigorous assessment of the efficacy of hyperbaric the efficacy of hyperbaric oxygen therapy is needed

An overview: origins and development of green chemistry

This article provides an overview of the origins and development of green chemistry. Aiming to contribute to the understanding of green chemistry, basically from a historical point of view, this overview argues that contextual influences and the user friendliness of the term are drivers for the explosive growth of green chemistry. It is observed that political support for its development has been significant, in which the Pollution Prevention Act of 1990 was a formal political starting-point, but informally the origins of green chemistry go back to before 1990. US EPA played an important role in all this, but did not solely contribute to the growth of green chemistry

HiGlass: web-based visual exploration and analysis of genome interaction maps

We present HiGlass, an open source visualization tool built on web technologies that provides a rich interface for rapid, multiplex, and multiscale navigation of 2D genomic maps alongside 1D genomic tracks, allowing users to combine various data types, synchronize multiple visualization modalities, and share fully customizable views with others. We demonstrate its utility in exploring different experimental conditions, comparing the results of analyses, and creating interactive snapshots to share with collaborators and the broader public. HiGlass is accessible online at http://higlass.io and is also available as a containerized application that can be run on any platform.National Institutes of Health (U.S.) (U01 CA200059)National Institutes of Health (U.S.) (R00 HG007583)National Institutes of Health (U.S.) (U54 HG007963
