Cognitive Vulnerability to Depression

Abstract: RICK E. INGRAM, JEANNE MIRANDA, and ZINDEL V. SEGALCognitive Vulnerability to DepressionNew York: Guilford Press, 1998, 330 pages(ISBN 1-57230-3042, US$36.95, Hardcover)Reviewed by KEITH S. DOBSONCognitive Vulnerability to Depression is a multi-authored text that addresses conceptual issues related to the idea that the way in which individuals think makes them vulnerable to either the onset or maintenance of depression. Methodological considerations for testing cognitive models of depression are also extensively discussed. The authors argue that vulnerability factors for depression can be logically divided into distal (more distant in time; typically endowed at birth, or due to early experience) and proximal (closer in time to the onset of depression; more likely recent experience) factors, and the review of the evidence is divided into this framework.The authors maintain that cognition can be broken down into four aspects: structural, propositional (focusing on internal components of cognition), operational (how components or processes function) and products (the outputs of cognitive functions). They utilize the concept of cognitive schemas to organize their thesis, and make a convincing case that this concept can accommodate the critical components of cognition in depression mentioned above. The schema concept is also critical to the arguments they make that individuals develop, as a result of their experience, a latent vulnerability that can be activated with the presence of sufficient negative mood or experiential inputs. The schema concept also helps to frame the authors' discussion of relapse vulnerability. Finally, the ideas that cognitive schemas are structurally necessary, but that their content is shaped by early experiences (which are fundamentally interpersonal in nature, related to life support, attachment and belongingness, and nurturance), explains why the authors conclude the book in an integrative manner, by saying that cognition should not be examined in the absence of content, and that it is likely that our "final models" of cognition will incorporate both cognitive and interpersonal processes.This book achieves its goals well. The literature is meaningfully reviewed, with clear ideas about what may be areas for fruitful future work, and areas that are likely not to be as productive. The research cited is very appropriate and up-to-date. There are many excellent research ideas pressed between the covers of this book. It is notable in this latter regard, however, that the issue of depressive realism, which has been debated in the theory and empirical literature, figures not at all in the current volume.One of the potential difficulties in a multi-authored text is that of unevenness in the quality or style of writing. It is a pleasure that such a problem does not emerge in this text. The style of writing is consistently high and the transitions are very good, indicative of excellent editing. …

Compensation Topologies of High-Power Wireless Power Transfer Systems

Abstract: Wireless power transfer (WPT) is an emerging technology that can realize electric power transmission over certain distances without physical contact, offering significant benefits to modern automation systems, medical applications, consumer electronics, etc. This paper provides a comprehensive review of existing compensation topologies for the loosely coupled transformer. Compensation topologies are reviewed and evaluated based on their basic and advanced functions. Individual passive resonant networks used to achieve constant (load-independent) voltage or current output are analyzed and summarized. Popular WPT compensation topologies are given as application examples, which can be regarded as the combination of multiple blocks of resonant networks. Analyses of the input zero phase angle and soft switching are conducted as well. This paper also discusses the compensation requirements for achieving the maximum efficiency according to different WPT application areas.

A bacterial driver-passenger model for colorectal cancer: beyond the usual suspects.

Abstract: Cancer has long been considered a genetic disease. However, accumulating evidence supports the involvement of infectious agents in the development of cancer, especially in those organs that are continuously exposed to microorganisms, such as the large intestine. Recent next-generation sequencing studies of the intestinal microbiota now offer an unprecedented view of the aetiology of sporadic colorectal cancer and have revealed that the microbiota associated with colorectal cancer contains bacterial species that differ in their temporal associations with developing tumours. Here, we propose a bacterial driver–passenger model for microbial involvement in the development of colorectal cancer and suggest that this model be incorporated into the genetic paradigm of cancer progression.

Active transportation and physical activity: opportunities for collaboration on transportation and public health research

Abstract: Physically inactive lifestyles are a major public health challenge, and research in the transportation field on influences on the choice to walk and bike may provide guidance toward solutions. In the interests of promoting effective collaboration among the transportation, planning, and health fields, the current paper was written to fulfill three purposes. The first purpose was to summarize the transportation and planning studies on the relation between community design and non-motorized (“active”) transport and to interpret these studies from a health perspective. The second purpose was to summarize studies from the health literature that examine the relation between physical environmental variables and leisure-time physical activity that have relevance for transportation research. The third purpose was to promote more collaboration among transportation, planning, and health investigators by identifying opportunities for transdisciplinary research.
