Birthing Support for Midwives and Mothers - ErgonomicTesting and Product Development
2012
Purpose: To further develop an ergonomic birthing support for increasing comfortable postures for midwives and mothers during deliveries. Methods and Results: First, the prototype of the birthing support and six birthing postures were tested with 8 midwives, 2 physicians, and 10 pregnant women in the last month of their pregnancy using visual analogue scales (VASs) and the System Usability Scale (SUS). According to the midwives and mothers, the best birthing postures were those with the mother sitting on the birthing support with the bed crosswise or the mother laying on her side on the bed with her leg on the birthing support. In the second stage of the study, 4 experts carried out an expe…
Is mate fidelity related to site fidelity? A comparative analysis in Ciconiiforms
2000
We tested for an association between divorce rate and site fidelity in 42 avian species belonging to the order Ciconiiforms, using comparative methods that account for the influences of phylogenetic relationships on the data. Our methods enabled us to detect evidence of correlated evolution and provided information on the temporal ordering of evolutionary changes in these two variables. We found a significant correlation between divorce rate and site fidelity, indicating that species with little or no site fidelity are more likely to divorce. Our data suggest that the coupled evolution of divorce and site fidelity can be summarized by three major events. The first event corresponds to a tra…
Keratoconus stage impact on visual acuity and contrast sensitivity.
2020
Contrast sensitivity decreases in keratoconus subjects even before the decrease is presented at high contrast visual acuity. The aim of our study was to estimate the subject’s contrast sensitivity and visual acuity in different keratoconus stages. In our study, there were included 45 keratoconus subjects (77 eyes) with the first, second and third keratoconus stages. Visual acuity and contrast sensitivity were measured at 3 m with the best possible spectacle correction and without vision correction using FrACT program 3.9.3. In the study, contrast sensitivity was measured at following spatial frequencies – 1, 3, 5, 7, 9, 11, 13 and 15 cpd. Contrast sensitivity analyse showed that there was a…
Sharing R&D investments in cleaner technologies to mitigate climate change
2014
This paper examines international cooperation on technological development as an alternative to international cooperation on GHG emission reductions. It is assumed that when countries cooperate they coordinate their investments so as to minimize the agreement costs of controlling emissions and that they also pool their R&D efforts so as to fully internalize the spillover effects of their investments in R&D. In order to analyze the scope of cooperation, an agreement formation game is solved in three stages. First, countries decide whether or not to sign the agreement. Then, in the second stage, signatories (playing together) and non-signatories (playing individually) select their investment …
Spin Doctors in the United States, Great Britain, and Germany: Metacommunication about Media Manipulation
2001
This study develops a new concept in political communication theory called metacommunication. It argues that metacommunication (1) describes a new, third stage in election coverage after issue and strategy coverage; (2) reflects the mass media's new role as a political institution in the third age of political communication; and (3) can be seen as the news media's response to a new, third force in news making: professional political PR. Metacommunication is defined as the news media's self-referential reflections on the nature of the interplay between political public relations and political journalism. While metacoverage can take two forms, self-referential news and process news, the pres…
