Qualitative interpretation and sampling validity of peer recognition study

In an examination of limitations to a previous study, it was found that there was no significant difference between respondents and non-respondents with regard to country or eminence of institution. Observations from non-respondents illustrate possible constraints on the interpretation of responses.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23847/1/0000086.pd

Visualizing the needle in the haystack: In situ hybridization with fluorescent dendrimers

In situ hybridization with 3DNA dendrimers is a novel tool for detecting low levels of mRNA in tissue sections and whole embryos. Fluorescently labeled dendrimers were used to identify cells that express mRNA for the skeletal muscle transcription factor MyoD in the early chick embryo. A small population of MyoD mRNA positive cells was found in the epiblast prior to the initiation of gastrulation, two days earlier than previously detected using enzymatic or radiolabeled probes for mRNA. When isolated from the epiblast and placed in culture, the MyoD mRNA positive cells were able to differentiate into skeletal muscle cells. These results demonstrate that DNA dendrimers are sensitive and precise tools for identifying low levels of mRNA in single cells and tissues

Self awareness of the supervisor in supervision

Teaching self awareness is an important and sensitive task in the supervision of the clinical casework student. However, lack of self awareness on the part of the supervisor may lead to a serious impaction of this learning process, and unfortunately, there is no institutionalized process for reviewing lack of supervisory self awareness as there is for students. Some occasions in which problems in supervisory self awareness are likely to occur are: the supervisor who has difficulty in responding appropriately to the student's dependency demands in supervision, responding either by withdrawing from the student or being overprotective of him; the supervisor who is threatened by students whose character styles are very different from his own; and the supervisor who views client behavior from the perspective of a value system very different from the student's.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44357/1/10615_2004_Article_BF00760155.pd

Simulating a nomination procedure

A snowball sampling procedure is simulated by computer. In snowball sampling, a small first-round sample of respondents, in this case editors of journals in several specialities, are asked to name second-round respondents to be contacted for a similar request for a third round, etc. In our survey, respondents were asked to nominate peer scientists for their contributions and expertise in their specialty. We used the simulation to estimate the effect of the number of rounds on the fraction of experts likely to be named, and to investigate the effect of other parameters. We found that it would take many rounds before every expert in a specialty is nominated. The simulation considered the effect of specialty subdivisions and showed how the distribution changes as the sample increases.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24938/1/0000365.pd

Together forever? Explaining exclusivity in party-firm relations

Parties and firms are the key actors of representative democracy and capitalism respectively and the dynamic of attachment between them is a central feature of any political economy. This is the first article to systematically analyse the exclusivity of party-firm relations. We consider exclusivity at a point in time and exclusivity over time. Does a firm have a relationship with only one party at a given point in time, or is it close to more than one party? Does a firm maintain a relationship with only one party over time, or does it switch between parties? Most important, how do patterns of exclusivity impact on a firm’s ability to lobby successfully? We propose a general theory, which explains patterns of party-firm relations by reference to the division of institutions and the type of party competition in a political system. A preliminary test of our theory with Polish survey data confirms our predictions, establishing a promising hypothesis for future research

How does community context influence coalitions in the formation stage? a multiple case study based on the Community Coalition Action Theory

<p>Abstract</p> <p>Background</p> <p>Community coalitions are rooted in complex and dynamic community systems. Despite recognition that environmental factors affect coalition behavior, few studies have examined how community context impacts coalition formation. Using the Community Coalition Action theory as an organizing framework, the current study employs multiple case study methodology to examine how five domains of community context affect coalitions in the formation stage of coalition development. Domains are history of collaboration, geography, community demographics and economic conditions, community politics and history, and community norms and values.</p> <p>Methods</p> <p>Data were from 8 sites that participated in an evaluation of a healthy cities and communities initiative in California. Twenty-three focus groups were conducted with coalition members, and 76 semi-structured interviews were conducted with local coordinators and coalition leaders. Cross-site analyses were conducted to identify the ways contextual domains influenced selection of the lead agency, coalition membership, staffing and leadership, and coalition processes and structures.</p> <p>Results</p> <p>History of collaboration influenced all four coalition factors examined, from lead agency selection to coalition structure. Geography influenced coalition formation largely through membership and staffing, whereas the demographic and economic makeup of the community had an impact on coalition membership, staffing, and infrastructure for coalition processes. The influence of community politics, history, norms and values was most noticeable on coalition membership.</p> <p>Conclusions</p> <p>Findings contribute to an ecologic and theory-based understanding of the range of ways community context influences coalitions in their formative stage.</p

The transition into adoptive parenthood: adoption as a process of continued unsafe uncertainty when family scripts collide

Our prospective study investigated couples’ expectations of adoptive parenthood and explored how these changed with their actual experience of parenthood. Six heterosexual couples were interviewed just before placement began and six months after the children had arrived. Interpretative Phenomenological Analysis (IPA) was used to analyse both sets of interview data. Expectations of adoptive parenthood mostly transformed smoothly into adoption experience for couples but challenges were experienced when family scripts collided and a continued feeling of unsafe uncertainty then prevailed within these newly formed family systems. Family script collision seemed a particular problem for couples adopting sibling pairs. To further professional practice in working with families over the transition to adoptive parenting we suggest that professionals keep in mind a framework that includes: Internal and external world influences on family members, Intergenerational issues, Family scripts, and the Structural challenges of adoption (IIFS)

Geographic patterns of choice among peers

Editors of key journals in six specialties were asked to name experts in their specialty from whom they would like to receive manuscripts and whom they would like to use as referees. The people so named were asked for their choice of experts, and similarly for the persons they nominated. The analysis of geographical factors revealed a similarity between nominations and citations. Most of the nominees were from the U.S., followed by the UK and other industrialized and traditionally scientific nations. The U.S. scientists have a higher probability of being nominated than their proportion in the world scientific population might suggest. Nominators in most of the countries had a distinctive preference for nominating their own countrymen, with the exception of the Soviet Union.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24241/1/0000504.pd
