Role Strain of Nursing Students in Obstetrical Clinical Rotations: Is Role Strain Greater for Male Students?

As increasing numbers of men enter the career of nursing, it is important that nursing educators identify areas of role strain and learning needs that may be different from their female counterparts This research project examined the role strain factors of nursing students who have completed the maternaVnewbom (obstetrical) clinical experience in a baccalaureate nursing program. The research question addressed in this research project was: Do male nursing students experience greater role strain than female nursing students in the matemaVnewbom setting? A convenience sample of male students (N=23) and a random sampling of female students (N=23) participated in this study. The Junior and Senior level nursing students who had completed the obstetrical rotation within the last 3 semesters were recruited to complete the Sherrod Role Strain Scale ( 40 question Likert scale survey tool) at specified times during fall semester 2008. Data was analyzed as grouped data and female/male responses were also compared. The overall score showed no gender differences in role strain (p value= 0.917). The four subcategories (Overload, Conflict, Incongruity, and Ambiguity) also did not reflect gender differences in this sample. The findings of this study did not support the concept of male students experiencing greater role strain than their female counterparts. Further studies examining role strain factors, student perceptions of role strain, and comparing men students in various nursing programs are recommended

The Morita equivalence between parametrized spectra and module spectra

We give a Quillen equivalence between May and Sigurdsson's model category of parametrized spectra over BG, and Mandell, May, Schwede, and Shipley's model category of modules over the orthogonal ring spectrum \Sigma^\infty_+ G, for each topological group G. More generally, for a topological category C we introduce an "aggregate" model structure on the category of diagrams of spectra indexed by C, and prove that it is Quillen equivalent to spectra over BC. This lifts several earlier results, and leads to a complete characterization of the dualizable parametrized spectra, answering a question of May and Sigurdsson.Comment: 24 pages, to appear in Contemporary Mathematic

Seasonal variation in the diurnal periodicity of activity of the perch, Perca fluviatilis L. [Translation from: Kalamies 1973(3) 3.]

The most common catch of the amateur angler is the perch and it is the diurnal periodicity of activity (& catchability) which is examined in this study based on earlier articles and manuscripts by the authors. Of all environmental factors, variation in light and temperature are the chief reasons in establishing the times of activity periods. Winter, summer and autumn activity was studied. The spawning perch was found to be more active than the non-spawning perch. The time of day in which the fish may be active is dependant on its ability to sense changes in the external environment. Its adaptation to light is the reason for day-activity in the winter, and also accounts for the fact that hardly any activity occurs between sunset and sunrise when this period exceeds 6 hours

Diurnal periodicity of activity in the spawning perch P. fluviatilis L. [Translation from: Kalamies 1972(7) 3, 1972]

Diurnal periodicity of spawning in the perch so far are rather meagre and found to be partly contrary to experiences of perch anglers. Therefore a study was made on the spawning during a 5-day period in the spring of 1971 in the Kuusamo area. Observations were made during the main spawning season, between 4- 9 June 1971. The perch were often measured, weighed and then released back into the water. The differences between spawning and non-spawning perch were studied as well as the time of roe discharge in a 24 hour period. Activity and environmental factors such as light intensity were also taken into consideration

Searching for optimal variables in real multivariate stochastic data

By implementing a recent technique for the determination of stochastic eigendirections of two coupled stochastic variables, we investigate the evolution of fluctuations of NO2 concentrations at two monitoring stations in the city of Lisbon, Portugal. We analyze the stochastic part of the measurements recorded at the monitoring stations by means of a method where the two concentrations are considered as stochastic variables evolving according to a system of coupled stochastic differential equations. Analysis of their structure allows for transforming the set of measured variables to a set of derived variables, one of them with reduced stochasticity. For the specific case of NO2 concentration measures, the set of derived variables are well approximated by a global rotation of the original set of measured variables. We conclude that the stochastic sources at each station are independent from each other and typically have amplitudes of the order of the deterministic contributions. Such findings show significant limitations when predicting such quantities. Still, we briefly discuss how predictive power can be increased in general in the light of our methods
