Effects of Beaver on Stream Flow and Water Quality

Bates, James W. 01 May 1963 (has links)
Water, one of the major resources of the western lands, controls the economy and expansion of the communities. Industry, agriculture, timber, livestock, game and home water needs are all dependent upon a steady and continued flow of water from wells, springs, and rivers. Water is derived from one source, precipitation, which occurs in the form of rain and snow. Watersheds which are properly managed accumulate a substantial snow pack during the winter which is the life-giving source of water for our springs. The Utah Water and Power Report (1948) indicates the annual precipitation over the entire state of Utah averaged 11.5 inches. A total of 53 ,000,000 acre-feet of water falls within the boundaries of the state of Utah each year, the amount varying with elevation and topography. The Bear River contributes an average of 725,000 acre-feet. A total of 2,334,000 acre-feet is carried away each year by streams leaving the state, leaving the net amount of 51 ,391,000 acre-feet to be consumed within the state. Water consumed on irrigated lands represents less than five percent of the total amount while evapotranspirational losses from the watersheds and grazing lands amount to almost 75 percent of the total water supply. Utah has approximately 1,500,000 acres of land suitable for agricultural production without a water supply; and of the 1,000,000 or more acres of irrigated land, only 25 percent has adequate and dependable supply of water. Droughty conditions and low water supplies are becoming more acute in the state of Utah each year, creating a need for water conservation.

The behavioural response of cattle (<i>Bos taurus</i>) to artificial weaning in two stages

Haley, Derek Bryon 03 July 2006
Two factors presumed to affect the behavioural response of cattle (<i>Bos Taurus</i>) to artificial weaning were investigated: the termination of nursing, and the physical separation of cows and calves. A two-stage process was used to disconnect these traditionally linked components. First, the behaviour of cows and calves was quantified in response to preventing nursing by having calves wear an antisucking device (Stage 1). Then the behavioural response of cows and calves to being separated was observed (Stage 2). Control pairs were weaned abruptly; nursing ended when cows and calves were separated. Preventing nursing while pairs were still together had almost no effect on measures of general activity with the exception of causing a slight increase in the rate of vocalizing. Calves wearing antisucking devices spent the same amount of time eating as controls. The behavioural responses of two-stage pairs to separation were favourably reduced compared to controls. In one study, two-stage cows vocalized 84% less than controls, spent 60% less time walking, and 13% more time lying, compared to controls. Two-stage calves called 97% less than controls, spent 61% less time walking, and 30% more time eating. In another study, preventing nursing for longer (3 versus 14 d) had no noticeable beneficial effects on the behaviour response to separation. In three separate trials two-stage calves gained more weight during the first week after separation from their dams. The two-stage process further reduced the behaviour responses when compared to weaning by fenceline contact. The benefits of two-stage weaning were also observed with dairy calves weaned from their dams at 5 weeks of age. The combined results of these studies indicate that the traditional method of weaning, by simultaneously terminating nursing and separating pairs, exacerbates the behavioural responses of cows and calves. Imposing these in two separate stages did not produce the same additive effect suggesting that the traditional weaning method produces a negative synergistic effect on the behaviour response. Based on the evidence two-stage weaning offers a viable production practice that is likely to improve the welfare of cows and calves.

Activity and enclosure use of a sand cat in Parken Zoo, Eskilstuna

Carlsson, Linett January 2009 (has links)
<p><strong>The escalating extinction of wildlife puts a high pressure on the standard of ex situ conservation. Some animals may spend several generations in captivity which may affect their natural behaviors and also a future reintroduction into the wild. Observations of animal behavior among captive animals are crucial for the understanding of ex situ conservation effects on behavior and in order to introduce and improve environmental enrichment. This study investigates activity and enclosure use of a sand cat (<em>Felis margarita</em>) at Parken zoo in Eskilstuna Sweden. Direct observations of behavior and movements were carried out and audience impact was also analyzed. The sand cat in the present study showed no behavioural response to the audience but it had some effect on his location in the enclosure. I also found that he was more active during late afternoon after feeding time and that he slept most during the forenoon. He used the whole enclosure to some extent but he spent most of his time in the cave, the front and the middle of the enclosure. Although he did not show any typical stereotypic behavior he had some odd habits that could probably be prevented through environmental enrichment. </strong><strong></strong></p>

The Influence of Atmospherics on Consumer Perceptions of Service Quality, Merchandise Price, and Merchandise Quality Influencing Behavioral Intentions: A Retailing Study of Outlet Malls

Holmes, Alycia Fogle 01 August 2007 (has links)
This study examines the influence of atmospherics on consumer perceptions of service quality, merchandise price, and merchandise quality influencing behavioral intentions in an outlet mall environment. The research design was a survey method and data were collected through a mall intercept questionnaire. A pilot test of the instrument was conducted with 43 subjects. The final questionnaire contained 30 items and a demographic section. A total of 586 questionnaires were collected from three different outlet malls. The results indicated that the atmospheric variables and the human variable of crowding are related to consumer’s perceptions of the service quality, merchandise price, and merchandise quality at an outlet mall. However, the atmospheric variables and the human variable of crowding were determined to not have a significant relationship to consumer behavioral intentions at the outlet mall. Other findings indicate that the consumer perception of service quality was determined to be significantly related to consumer behavioral intentions. However, the consumer perceptions of merchandise price and merchandise quality at the outlet mall were determined to not have a significant relationship with consumer behavioral intentions. Managerial and theoretical implications are discussed along with future research suggestions.

Job Satisfaction and Work Ethic among Workers in a Japanese Manufacturing Company Located in the United States

Elkins, Samuel L 01 May 2007 (has links)
This correlational and descriptive study synthesizes previous research regarding the impact of work ethic on job satisfaction when moderated by demographics, work dynamics, and occupational choice. Data from a sample of both exempt and non-exempt workers working at a Japanese-owned manufacturing plant was used to explore the relationship between the levels of job-satisfaction and work ethic reported by workers in various job categories and working environments. The sample consisted of 462 individuals who were identified using a stratified sampling of equal size. The study obtained responses from 328 workers through a respondent and non-respondent survey, representing 70% response rate. The researcher concluded that the 66 non-respondents could be included in the statistical analysis without prejudice toward the OWEI instrument; however, special attention should be given to any findings involving the JSS subscale Fringe Benefits due to differences between respondents and non-respondents. Specials examination was also given to the demographic variables of age and country. The researcher employed two robust tests, Wilks’s Lambda and Pillai’s Trace, to mitigate differences between respondents and non-respondents. Exempt workers made up 46.6% of the sample, and non-exempt workers represented 53.4%. The researcher used the Pearson r and the Multiple Analysis of Variance (MANOVA) in analyzing data. The OWEI and JSS instruments showed an overall positive, by low though significant correlation. Differences were identified between exempt and non-exempt workers in various job categories. This study should be of value to human resource practitioners interested in improving the level of job satisfaction among varied work groups.

Analysis of Tourists Attending a Culinary Event: Motivations, Satisfaction, and Behavioral Outcomes

Smith, Sylvia 01 August 2007 (has links)
The study constructs a causal model of culinary tourist behavior from the theoretical framework of push and pull motivations and related concepts with regard to satisfaction and behavioral intentions. Respondents were distinguished with regards to socio-demographic characteristics, travel behavior, and importance of event attributes. Further, importance-performance hypothetical framework was utilized to measure pull motivations. The study proposed that culinary event attendees’ expenditures, word-of-mouth behavior, and repeat patronage intentions would be related to their overall event satisfaction. Culinary event attendees were segmented on the basis of push motivations. Using factor, cluster, and multiple regression analyses with data collected from an international culinary event, the study examined the above relationships. The results of the analyses can be summarized as: 1) food event, event novelty, and socialization were the push motivations identified for attending a culinary event, 2) motivations were clustered into two meaningful segments: Food Focusers and Event Seekers, 3) the two clusters statistically were different from each other based on gender, age, income, education, and expenditures, 4) on all event attributes, with the exception of nightlife, performance means were significantly lower than importance means, 5) food product, support services, and essential services had a significant predictive affect on overall satisfaction, and 6) overall satisfaction had a significant relationship with outcome variables (expenditures, word-of-mouth behavior, and repeat patronage). This research makes unique contributions to the area of consumer research in culinary tourism from both the theoretical and empirical perspectives. It is believed that results of the present study will be useful to organizers of culinary events and/or destination managers.
