A) Bland-Altman plot comparing differences between internal derived muscle density values and hydroxyapatite (HA) bone phantom derived muscle density values (n = 10 muscle samples). B) Bland-Altman plot comparing differences between the sucrose water phantom derived muscle density values and hydroxyapatite (HA) bone phantom derived muscle density values (n = 10 muscle samples). Internal and sucrose water phantom derived muscle density values are represented in g/cm3. HA phantom derived muscle density values are represented in mgHA/cm3. (TIFF)</p

Effects of a 1970 restoration planting on soil in the Carleton College Lower Arboretum, Northfield, MN
No full textThe species mix in a forest is commonly limited by soil composition. At the same time, the composition and chemistry of a soil can be controlled by the forest above. This study looks at the effects of a 1970 restoration planting (the Earth Day Forest) in the Lower Arboretum of Carleton College on soil chemistry by testing for important elements. The results of the tests are then compared to data from an uncultivated forest (the non-Earth Day Forest). The species mix chosen for the Earth Day Forest in 1970 was markedly different from the original forest, today the restoration planting is dominated by Juglans nigra (Black Walnut), a species not seen in the non-Earth Day Forest. Comparisons of the Earth Day Forest to the non-Earth Day Forest in the fall of 2011 showed that the Earth Day Forest had lower rates of total C and N in the soil, as well as lower rates of soil organic matter. The allelopathic nature of Juglans nigra has drastically reduced diversity in the Earth Day Forest. Due to its lower rate of N immobilization, the succession of Juglans nigra from the 1970 restoration has lengthened the time required for a former agricultural field to return to a pre- agricultural state
Bland-Altman plot for subject S2.
No full textBland-Altman plot with reference kinematics (absissas) and difference (ordinates) between model-derived and reference fluoroscopy-based kinematics. From left to right Bland-Altman plots for models N, S, P, M respectively, corresponding to joint angles and displacements, from top to bottom EF, AA, IER, and LM, AP and PD, respectively. Differences between model-derived kinematics and fluoroscopy-based kinematics are plotted against reference amplitude of movement (angle or displacement). Thick black line represents the bias (mean of the differences) whose value is designated by b, thin black lines represent the limits of agreement whose value is designated by l = b ± 1.96 standard deviation. Squared Pearson’s correlation coefficient (r²), root mean square error (rmse) and standard deviation (sd) are displayed for each graph.</p

Intolerance of uncertainty: A temporary experimental induction procedure
No full textBackground and Objectives
Intolerance of uncertainty (IU) is a trans-diagnostic construct involved in anxiety and related disorders. Research focused on cross-sectional reporting, manipulating attitudes toward objective and impersonal events or on treatments designed to reduce IU in clinical populations. The current paper presents an experimental procedure for laboratory manipulations of IU and tests mediation hypotheses following the Intolerance of Uncertainty Model.
Methods
On pre-test, undergraduate volunteers (Study 1, n = 43;68% women. Study 2, n = 169;83.8% women) were asked to provide an idiosyncratic future negative life event. State-IU, Worry, Positive and Negative Affect were assessed after that a standardized procedure was used to identify event’s potential negative consequences. The same variables were assessed on post-test, after that participants were asked to read-through increasing and decreasing IU statements.
Results
Temporary changes on IU were consistently reproduced in both studies. Participants receiving increasing IU instructions reported greater state-IU, Worry and Negative Affect than those receiving decreasing IU instructions. However, this latter condition was not different from a control one (Study 2). Both studies revealed significant indirect effects of IU induction instructions on Worry and Negative Affect through state-IU.
Limitations
Both studies used undergraduate psychology students samples, younger than average population and predominantly female. Experimental manipulation and outcome measures belongs to the same semantic domain, uncertainty, potentially limiting generalizability.
Conclusions
Results supported the feasibility and efficacy of the proposed IU manipulation for non-clinical sample. Findings parallel clinical research showing that state-IU preceded Worry and Negative Affect states
Life on the land : the interrelationship between identity and community in the Irish fiction of Maria Edgeworth, William Carleton and Charles Lever
No full textThis thesis examines and evaluates the response made by three
nineteenth century Irish writers of fiction to the most pressing
social problem of their time, namely: How might life on the land
be firmly established and maintained? The three writers concerned
— Maria Edgeworth, William Carleton and Charles Lever — are shown
to possess a common artistic vision, which is preserited as an answer
to the question posed. The answer consists of a demonstration of
how the resources of an enabling individual must blend with the
requirements of life on the land as it is.
By way of introduction, the significance of the theme for
both the literary and socio—political contexts of the period
(1800-1872) is described, and the problems of dealing with-nineteenth
century Irish fiction — problems concerned with its status
in the national cultural heritage, its variety and its artistic
characteristics — are outlined.
The four Irish novels of Maria Edgeworth are given a special
status in her overall output, and her handling of the theme in them
is considered as the prototype of her successors' manner of dealing
with it. Carleton and Lever are taken as portraying the Edgeworth
model under stress. Carleton's work is represented by a selection
of pieces from his Traits and Stories of the Irish Peasantry;
Lever's by three novels from the 1850's and '60's. All three
writers are located in their contemporary cultural milieux, and
their individual treatments of the theme are described and compared.
In conclusion, a general characterisation of the type of fiction
produced by the trio is offered, and a basis for its artistic
relationship to Irish fiction of more recent times is rehearsed.
The thesis facilitates a new periodisation of the history of
nineteenth century Irish fiction. It also offers a revised
conception of a tradition, of Irish fiction. These are the
contributions it makes to knowledge of the subject treated
