Clustering Methods with Qualitative Data: a Mixed-Methods Approach for Prevention Research with Small Samples.

Qualitative methods potentially add depth to prevention research but can produce large amounts of complex data even with small samples. Studies conducted with culturally distinct samples often produce voluminous qualitative data but may lack sufficient sample sizes for sophisticated quantitative analysis. Currently lacking in mixed-methods research are methods allowing for more fully integrating qualitative and quantitative analysis techniques.

Differential expression of central metabotropic glutamate receptor (mGluR) subtypes in a clinical model of post-surgical pain.

Tissue damage during surgery can induce 'central sensitization' and the development of pain and hyperalgesia post-operatively. Metabotropic glutamate receptors (mGluRs) contribute to nociception, inflammatory pain and hyperalgesia. This study characterized the temporal expression of group I (mGluR(1), mGluR(5)) and II (mGluR(2), mGluR(3)) mGluRs in spinal cord following abdominal surgery.

On community leadership: stories about collaboration in action research.

This article provides an account of a 10-year collaborative documentation of community leadership in an African American community on the South side of Chicago. The stories are oriented to several critical incidents in the life course of the collaboration. They are told from the perspectives of one university professor, four graduate students, and one community leader.

Up-regulation of metabotropic glutamate receptor subtypes 3 and 5 in spinal cord in a clinical model of persistent inflammation and hyperalgesia.

Evidence from experimental pain research has revealed that metabotropic glutamate receptors (mGluRs) play a pivotal role in nociceptive processing, inflammatory pain and hyperalgesia. The aim of this study was to characterise expression of group I and II mGluRs in spinal cord in a model of naturally occurring persistent inflammation (sheep with unilateral lameness due to inflammation of the digital tissues of the feet, estimated to have been affected by the condition for >2 weeks) and an experimental model of acute inflammation (injection of intradermal carrageenan into lower forelimb in sheep). Animals with unilateral clinical inflammation displayed significant mechanical hyperalgesia on the affected limb.

Science and community psychology: social norms for pluralistic inquiry.

The concept of "science" linked to the concept of "community psychology" requires adaptation. In the case of community psychology, science is public to citizens as well as to the scientist. The community psychologist, as scientist, works from the expectation that choices of topics, methods, and interpretation of findings are done in concert with representatives of the community.

Transient up-regulation of spinal cyclooxygenase-2 and neuronal nitric oxide synthase following surgical inflammation.

Background: Surgery induces pain and hyperalgesia postoperatively. The products of cyclooxygenases and nitric oxide synthase (NOS) have been implicated in the development of inflammatory pain and hyperalgesia experimentally, and the use of drugs clinically that modify cyclooxygenase activity has been advocated in the management of perioperative pain. However, regulation of these enzymes following surgery has not been studied.

The spirit of community psychology. 2001 Seymour B. Sarason Award Address.

Community psychology as a field may have lost some of its original spirit; a spirit dominant at the founding of the field. Spirit is a difficult concept to discuss since it is a concept beyond usual discourse in psychology as a denotative, measurable and verifiable concept. Taking the lead from William James, Spirit, however elusive, is most essential to a sense of self.
