Survival of Hand-reared Mallards (Anas platyrhynchos) on Artificial Farm Ponds

The survival of hand-reared, game-farm mallards released on artificial farm ponds was studied in Goodhue County, Minnesota. Of the 300 ducklings released each year from 1965 through 1967, an average of 45 per cent survived until most were capable of flying. More ducklings survived when released on ponds fenced from livestock than on unfenced ponds. Grazing livestock severely reduce cover vegetation around unfenced ponds. A total of 3.7 per cent of the bands were recovered. The first year recoveries represent 64 per cent of all the bands reported. Thirty-nine per cent of the band recoveries occurred within 15 miles of the release site

Migration and Mortality of Banded Mourning Doves

Banding data gathered over a three-year period at Savage, Minnesota, were analyzed to determine migration patterns and mortality rates of 2,218 mourning doves. The age ratio among trapped doves was 1.19 immatures per 1 adult and the sex ratio 3.84 males per 1 female. The weighted mean annual mortality rate for immature doves was 58.5 percent. For adult doves, the weighted annual mortality was 28.2 percent. The total weighted recovery rate was 1.24 immatures to 1 adult. The data show that immatures are 75 percent more vulnerable than adults to being shot; although no difference was found in direct recovery rates between immature and adult birds. Correction for differential vulnerability of sexes on basis of banding data showed that females were 143 percent more likely to be shot. The rate of migrational homing was not calculated, but data suggest that a high proportion of the surviving individuals homed to their natal area. Distribution of recoveries shows south, southeasternly and southwesternly migration patterns. The Central Management Unit accounted for 69 percent of the total recoveries. Most of the outstate recoveries were in Texas, with Florida recoveries second

thesisThis study analyzed the incidence of breast feeding and reasons for weaning among women in Utah. A convience sample population of 274 was obtained from women who were 3 months to 1 year postpartum. The time of weaning was found to be significantly associated with the following reasons for weaning: breast and nipple problems (t=.760, p<.01), the physician advising a woman to stop breast feeding (t=.741, p<.01), and a baby eating a good diet and taking liquids from a cup (t=.613, p=<.01). The rural sample was too small in comparison to the urban group to analyze difference between these two groups. Supportive individuals, especially the husband or partner, were important to most women. In the majority of situations, the support person decreased the incidence of early weaning. Sociodemographic variables were also found to be associated with specific reasons for weaning. Finally, those who enjoyed breastfeeding, weaned later. The incidence of breastfeeding a youngest child within the sample was 83.9%. Only 37% were still breastfeeding after 6 months. A higher incidence of breast feeding was found among women with higher educational achievements, within Protestant and Latter-Day Saints (LDS) religious groups and among married and divorced woman. If a woman had breast fed her youngest child (t=.438, p<.01). Regressional analysis shoed the best predictors of breast feeding were a woman having breast fed a previous child, accounting for 22.28%, and educational level (7.36%), The best predictors of the time of weaning were the enjoyment of breast feeding (12.07%) and the incidence of breast and nipple problems. (9.33%)

Controlling Administrative Sanctions

This Article will consider some of the possibilities for controlling and guiding the SEC\u27s discretion to impose sanctions upon broker-dealers. Although it is limited to an examination of the Commission\u27s practice and a discussion of possibilities for reform, the analysis contains obvious implications for any agency with the power to impose sanctions

Continuity Information and Etiological Explanations: Influences on Mental Health Stigma

The current study attempted to assess how the type of etiological explanations for symptoms and the belief of continuity of mental illness affected the rates of reported stigma scores in 58 Winona State University students. Participants were assigned to read one of four vignettes describing a fictional character that had depression. Each was as similar as we could make them while differing in the etiological explanation (caused by biogenetic factors or psychosocial factors) of the mental illness as well as describing the character as being on a continuum or having a dichotomous experience. All the participants took the Community Attitudes Towards the Mentally Ill scale (CAMI) to assess levels of stigmatized attitudes after reading the vignette. The CAMI measured for four facets of stigma (authoritarianism, benevolence, social restriction and community mental health ideology). Two-way factorial ANOVAs indicated that there were no significant effects found for either the etiological explanation or the belief of continuity of the four stigma facets. There was also no interaction found between the belief of continuity and the etiological explanations that affected rates of stigmatized attitudes in participants.https://openriver.winona.edu/urc2019/1108/thumbnail.jp
