Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland Dec 2000

Breastfeeding Personal Efficacy Beliefs Of Women University Students, Ann Pollard Cleveland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many women do not initiate breastfeeding although breastfeeding promotes their baby's health. Three reasons why women do not breastfeed are women's mental organization, cultural beliefs about breastfeeding, and women's breastfeeding personal efficacy beliefs. The conceptual framework for personal efficacy beliefs is Bandura's social-cognitive theory (1992, 1995, 1997). This dissertation used a new research instrument to examine women university students' breastfeeding personal efficacy beliefs. The instrument was tested by mail survey techniques that resulted in a 70.6% respondent rate. University women's personal efficacy beliefs about breastfeeding factored into five factor subscales. In order of magnitude, the personal efficacy belief factors were …

Teacher Videotaping As A Method Of Self -Assessing Questioning Skills In Secondary Public Schools, Stephen Alan Alberts Ii Dec 2000

Teacher Videotaping As A Method Of Self -Assessing Questioning Skills In Secondary Public Schools, Stephen Alan Alberts Ii

Graduate Theses, Dissertations, and Problem Reports (ETD)

Primarily this action research project was designed to hone my ability to Socratically question students by reflecting on my teaching through the lens of a videocamera---while reconciling my own paradigm with as many outside assessment devices as possible. The paramount consideration of my questioning/framing references was to incite students to think critically (see Pedagogical Skills Honed in chapter seven). The higher priorities of the outside assessors, on the other hand, were more political than instructional in nature (see Reconciling Multiple Assessments in chapter seven).;Scrutinizing and improving my questioning skills (the focus of the research) led to the epiphany that the …

Evidence For A Systemic Embryotoxic Effect Of Early Luteal Regression In The Ewe, Beth Alyson Costine Dec 2000

Evidence For A Systemic Embryotoxic Effect Of Early Luteal Regression In The Ewe, Beth Alyson Costine

Graduate Theses, Dissertations, and Problem Reports (ETD)

Experiments were performed to determine if a short-lived corpus luteum was embryotoxic in ewes given supplemental progesterone and the route of transfer of embryotoxic products. Mated ewes were lutectomized or sham lutectomized on day 4 after estrus. Following surgery, ewes received saline or PGF 2alpha through days 6 or 7. Pregnancy rate was reduced after treatment with PGF2alpha (P < 0.001) compared to controls and was increased in PGF2alpha-treated ewes by lutectomy (P < 0.05). Mated ewes with bilateral ovulations were unilaterally lutectomized, and each uterine horn was ligated to eliminate intercornual flow on day 4 after estrus. Treatment with PGF2alpha on day 5 through 8 reduced pregnancy rates (P < 0.01), but embryonic survival did not differ in the uterine horns ipsilateral or contralateral to the regressing CL. The regressing CL is embryotoxic in progesterone-supplemented ewes, and embryotoxic luteal products have been shown to act by non-local pathways.

Factors Influencing Brook Trout (Salvelinus Fontinalis ) Abundance In Forested Headwater Streams With Emphasis On Fine Sediment, James Philip Hakala Dec 2000

Factors Influencing Brook Trout (Salvelinus Fontinalis ) Abundance In Forested Headwater Streams With Emphasis On Fine Sediment, James Philip Hakala

Graduate Theses, Dissertations, and Problem Reports (ETD)

The influence and relative importance of fine sediment on wild brook trout (Salvelinus fontinalis) population size was assessed. Brook trout production in headwater streams was inversely proportional to substrate permeability in one of two years, suggesting substrate composition influenced production. Results suggest the critical fine sediment size for brook trout in this study, is between 0.063 mm and 1.0 mm. Further, fine sediment (<0.063 mm) should not exceed 0.6--1.0% of spawning substrate, or negative population effects may be incurred. Under normal flow conditions, fine sediment was a principal determinant of juvenile trout abundance relative to other physical and biological factors. Adult trout abundance was principally a function of stream discharge, and is potentially further influenced by fine sediment impacts on juvenile recruitment. Spatially restricted food resources, created by drought-induced low flows in year 2 of the study, are believed to have over-powered mechanisms influencing trout abundance under normal flows.

On The Feasibility Of Integrated Optical Waveguide-Based In Situ Monitoring Of Microelectromechanical Systems (Mems), Kolin Shay Brown

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the feasibility of using integrated optical waveguides to measure the motion of microelectromechanical structures (MEMS). MEMS are a class of silicon devices which are being developed as sensors and actuators. Because these free moving structures are fabricated using processes similar to microfabrication, MEMS devices and traditional electronics can be integrated on the same substrate. This merging of the technologies will allow the miniaturization of large scale mechanical systems. A difficulty with MEMS devices is determining the submicron motion. One method of noninvasive measurement is optical measurement. Research focused on the characterization of one particular MEMS device, a …

Adapting Parent -Child Interaction Therapy To Train Head Start Teachers In Behavior Management, Alisa B. Bahl Aug 2000

Adapting Parent -Child Interaction Therapy To Train Head Start Teachers In Behavior Management, Alisa B. Bahl

Graduate Theses, Dissertations, and Problem Reports (ETD)

Efforts toward greater inclusion of children with a range of presenting problems have resulted in increasingly more children with difficult behavior in non-specialized classrooms. Unfortunately, teachers report that they have not been trained adequately to work with children who exhibit extreme behaviors. It is important, therefore, that effective methods of training teachers are empirically investigated. In clinical settings, strategies for training parents of young children with disruptive behavior disorders have substantial empirical support. Therefore, using these techniques to train teachers is a logical step. Parent-Child Interaction Therapy is one empirically validated parent training approach that uses coaching as a means …
