    Examining the effect of program design on career and technical program completion, technical skill attainment and job placement

    Community college career and technical education programs struggle with meeting federallyunded Perkins performance measures. To address this need the 30-45-60 program design was developed. The study purpose was to determine if the 30-45-60 program design influenced career certificate, technical certificate or Associate of Applied Science degree completion rates, technical skill attainment, and job placement rates for students enrolled in the welding, precision machining and manufacturing and electrical technology programs. A Chi-square test of independence indicated no significantly significant relationship between the 30-45-60 program design and completion of a certificate or degree (p = .222). A closer look revealed no significantly significant relationship between the 30-45-60 program design and the career certificate (p = .392) or the Associate of Applied Science degree (.576) but was statistically significant for technical certificate (p = .000). A statistically significant relationship was found for technical skill attainment (p =.038) and job placement (p = .000)

    A clinical comparison of three astigmatic tests

    Astigmatism is a refractive condition in which the optical system of the eye cannot form a point image of a point object. This is a consequence of varying curvatures of the cornea and or the lens of the eye and is present in a large majority of the detection of astigmatism. This study takes a look at three subjective tests for astigmatism. Two of these, the Jackson cross cylinder and the Pratt near cylinder, are well established tests used at Pacific University clinics. The third test was designed by Dr. William Preston. Dr. Preston’s technique utilizes a near point card with a sunburst target which presents a series of radially arranged lines every 15 degrees. The card also presents three lines of Snellen acuity letter, 20/40, 20/30, and 20/20, which are used in fogging and cylinder axis refinement. This study concluded that there was no statistical difference between the magnitude and direction of the astigmatic refractive error found by the Preston technique and the Jackson cross cylinder. In addition, the study found that there was a statistically significant difference between the magnitude and the direction of the astigmatic refractive error found by the Preston technique and the Pratt near cylinder. Although these results were statistically significant, the clinical difference between the tests was minimal

    Risk and Protective Factors for Secondary Traumatic Stress and Burnout Among Home Visitors

    The overarching goal of this study was to understand the context of home visitor secondary traumatic stress and burnout, and how this might affect intention to quit among home visitors, particularly focusing on potential risk factors and supportive strategies identified by the home visitors. All home visitors providing services in the state in which the research was conducted (N = 27) completed a structured interview and a quantitative survey at two time points, 6 months apart. Results indicated that more than two-thirds of the home visitors experienced either medium or high levels of secondary traumatic stress and burnout over the course of the study. Approximately one quarter of home visitors indicated thinking of leaving their present positio. Qualitative data indicated that risk factors associated with burnout included those related to both direct and non-direct services. Risk factors associated with secondary traumatic stress included traumatic stress of families, inability to recognize one’s own experiences of secondary traumatic stress, and unhealthy work culture. In terms of protective factors, home visitors strongly emphasized the importance of having a supportive supervisor who they could trust and communicate with openly

    Managing an urban forest: Have street tree populations of Acer platanoides invaded forested parks?

    This study examined the existing, or potential, risk of invasion by street trees into an urban forested park (Breithaupt Park, a 32.5 hectare semi-forested park, and its surrounding residential neighbourhood in the City of Kitchener.). The primary research question is: What are the spatial distribution and dispersal patterns of street trees and park trees in urban areas? For street populations, height, crown spread, diameter at breast height (DBH), tree condition, trunk condition and foliage transparency were measured. Qualitative tree health indicators were used to gauge the condition of the street tree population only. For trees in Breithaupt Park, a point-quarter sampling method combined with a line-plot sampling method was used. There were 33 identified (and several unidentified) species of street trees and 24 identified species of forest trees. Acer platanoides was the most abundant street tree species, while Acer saccharum was the most abundant forest tree species. 52% of the street tree population and 9% of the forest tree population were exotic species; however, the exotics were mainly species not originating from the nearby streets (i.e. Rhamnus cathartica). Despite the well-established population of exotic invasive species such as Acer platanoides on the streets, spatial assessment of the nearby forested park revealed that relatively few exotic species had actually established there. Acer platanoides composed 1.9% of all trees, 3.2% of all saplings and 2.7% of all seedlings in the forest sample. The four possible sources of Acer platanoides seeds were trees planted on the street, trees planted in backyards, the leaf drop site in the parking lot of Breithaupt Park (only in the fall) and trees potentially planted directly in the forest. Explanations for the lack of invasion by Acer platanoides (in particular) include: 1) houses located between Acer platanoides street trees and Breithaupt Park functioning as a barrier to seed dispersal; 2) the highway traversing the northeast corner of the park; 3) the short length of time since Acer platanoides street trees reached their age of maturity to produce enough viable seeds to invade the forest and the lag time in the establishment phase; 4) unique park characteristics; and 5) opposing predominant wind directions. While Acer platanoides may be more invasive under different circumstances, it was concluded that Acer platanoides is not currently invading the park at a considerable rate but may be tending towards a future invasion. The main recommendations are: 1) to not cut down the Acer platanoides currently growing as street trees as they do not pose a high risk of invasion (though this is specific to the current study); 2) to manage the forest for invasive species and remove and restore the ecology of the forest as necessary; 3) to remove Acer platanoides currently growing in the forest; and 4) to replace dead street trees with non-invasive, hardy native trees instead of the historical planting of Acer platanoides and other exotics, in case the risk of invasion changes because of climate or urban design changes
