Correlates of Condom Use among Single, Sexually Active Ontario Adults: Data from the 1996/97 Ontario Health Survey

Ip, David Tai Wai 21 March 2012 (has links)
OBJECTIVE: To examine the past-year prevalence and frequency of condom use and to identify correlates of condom use among young, unattached heterosexual Ontarians. METHODS: Descriptive statistics and multiple logistic regression were used to analyze the 1996/97 Ontario Health Survey (OHS), a cross-sectional, random digit-dialling (RDD) survey of 36,892 Ontario residents of households with a telephone line. RESULTS: Between 1996 and 1997, 61.3% (95% CI=58.5%-64.1%) of the study sample (aged 15-44, n=1,949) reported consistent (always) condom use and 11.8% (95% CI=10.2%-13.5%) reported never using condoms. Significant correlates included, for both sexes, health planning region, age, ethnic origin, and type of smoker; for females only, socio-economic status, age at first sexual intercourse, and past-month oral contraceptive use ; and for males only, number of past-year sexual partners, HIV testing history, and past-year frequency of religious attendance. CONCLUSIONS: Findings constitute a cross-sectional component for examining the long-term trend of condom use in Ontario.

An exploration of the relationship between use of parks and access, park appeal, and communication effectiveness

Walker, Jamie Rae 15 May 2009 (has links)
Understanding what variables influence park use would assist park providers and policy makers in acquiring, designing, managing, and funding initiatives which encourage or support park use. Previous studies indicate that access to parks (measured by both objective and perceived distances), park appeal in terms of being well-maintained, and effective communication between constituents and park suppliers, relate positively to park use. This study explores the relationships between access, appeal, and communication and park use. Access is operationalized as four objective distances from household to nearest park using both Euclidian and Network measures, and by subjective self-reported measures of ability to access parks on foot or by bicycle. Appeal is concerned with the influence of parks’ perceived level of maintenance and availability of amenities on the probability of park use. Effective communication is operationalized by three variables: perceptions of being well-informed, being included in the planning process, and being able to give feedback to park leaders. These variables and selected demographic data were extracted from an existing data set: the City of College Station Needs Assessment. Findings indicated that a) respondents with access to parks are more likely to use parks, b) level of maintenance and available amenities influenced use, and c) respondents who are well-informed are more likely to use parks.

Changing patterns and perceptions of water use in east central texas since the time of anglo settlement

Patzewitsch, Wendy Winborn 15 May 2009 (has links)
Patterns and perceptions of water use have changed since Anglo settlement in Texas in the early nineteenth century. Change has not been constant, gradual, or linear, but rather has occurred in fits and spurts. This pattern of punctuated equilibrium in water use regimes is the central finding of this dissertation. Water use is examined in terms of built, organizational, and institutional inertias that resist change in the cultural landscape. Change occurs only when forced by crisis and results in water management at an increasing scale. Perception is critical in forcing response to crisis. Four water use regimes are identified. The agrarian regime was characterized by individual family and plantation units that were self-sufficient in their water supply. Water was perceived as abundant, but used sparingly. The agrarian regime began with Texas’s declaration of independence from Mexico in 1836 and lasted for the remainder of the nineteenth century. The waterworks regime was characterized by the introduction of piped water. During this second regime, water was still perceived as abundant, but was also taken for granted. The crisis forcing the waterworks regime was the need for better fire protection in cities. The almost constant threat of flood and drought, underscored by the Drought of the 1950s, in conjunction with a demographic shift, brought about the dam and levee regime. As a consequence of the Drought of the 1950s, water was for the first time perceived as scarce. We have just entered the groundwater regime. Recent water legislation and a state supreme court decision in favor of a bottled water company are putting new emphasis on groundwater sales from rural property owners to municipal water companies. Empirical studies supporting this theoretical framework are drawn from the heretofore unpublished 1868 journal of Pleasant B. Watson, from municipal bond records in the archives of the Texas Comptroller, from the early history of the waterworks at Bryan, Texas, from newly discovered records of a levee along the Brazos River, from an overview of dam and reservoir construction, and from a recent proliferation of groundwater districts.

Use-wear analysis of the Clovis biface collection from the Gault site in central Texas

Smallwood, Ashley Michelle 15 May 2009 (has links)
Use-wear studies were undertaken to determine if the Clovis bifaces discovered at the Gault site in Central Texas were utilized implements or rather products of lithic raw material procurement. Those bifaces bearing microscopic traces indicative of use were studied in detail to determine the use-history of the tools. This thesis describes an experimental program aimed to build analogues for probable biface functions. A series of projectile impact studies, butchering experiments, and expedient-like tool useactivities were conducted to document the traces acquired on the tool surface from use. The experimental results are used to identify the utilized tools, demonstrate their functional purpose, and suggest the extent of tool use of the prehistoric biface assemblage.

A Research on Legal System of Use of Police Weapons

Lin, Kuo-Liang 05 September 2006 (has links)
Based on the fundamental ideas of democratic country under the rule of law, the thesis deems that executing public power requires administration by rule of law. As police officers execute their duties, the use of police weapons is the most forcible and lethal tool among strong measures of obviating danger. Therefore, police officers must pay attention to the occasion and procedure of using their weapons. Because any careless use of police weapons easily harms people¡¦s life, body, freedom, property, rights, and interests, police officers must use their weapons carefully and properly. Scholars have provided lots of valuable opinions about the use of police weapons in the past and the police agency also emphasizes on the importance of correct use of police weapons. Moreover, the thesis discussed many cases about ¡§Correct use of police weapons,¡¨ ¡§Improper use of police weapons,¡¨ and ¡§Illegal use of police weapons¡¨ of police officers to offer responsibility problems which involve illegal use of police weapons possibly; expects the behavior of using police weapons can conform to law, order and human rights more to enhance the quality of using police weapons. In other words, making police officers use their weapons more correctly through the research on legal system of use of police weapons use can ensure not only rights and interests of common people, but also of police officer themselves. To view the thesis, ¡§A research on legal system of use of police weapons,¡¨ it mostly expounded with views of administrative law and analyzed and discussed according to five frames, including basic principles of legal system of use of police weapons of administrative law, legal system of administrative organizations, legal system of administrative limits of authority, legal system of administrative relief, legal system of administrative supervision. The thesis has seven chapters and the gist of each chapter is set forth as below: Chapter 1 Introduction- It introduced the motive, objective of the research, research scope and limits, research frame and methods, relevant phrases explanation, and literature review. Chapter 2 Basic Principles of Legal System of Use of Police Weapons- It simply discussed basic principles of use of police weapons, internationalism, spirit of law and order, and participation of person concerned. Chapter 3 Administrative Organizations of Legal System of Use of Police Weapons- It explained basic concepts of administrative organizations, administrative organization frame of legal system of use of police weapons, funds of legal system of use of police weapons, personnel system of legal system of use of police weapons. Chapter 4 Authority Design and Application of Legal System of Use of Police Weapons- It introduced administrative plans of legal system of use of police weapons, administrative legislation of legal system of use of police weapons, administrative disciplinary action of legal system of use of police weapons, administrative investigation and instant enforcement of legal system of use of police weapons, administrative contract of legal system of use of police weapons, assured means of obligation performance of legal system of use of police weapons, and administrative procedure of legal system of use of police weapons. Chapter 5 Relief and Aftercare of Legal System of Use of Police Weapons- It described the meaning, types of administrative relief of legal system of use of police weapons, petition, appeal, administrative lawsuit, national compensation, constitution interpretation, and plebiscite. Chapter 6 Supervision and Evaluation of Legal System of Use of Police Weapons- it introduced the outline of administrative supervision, internal and external supervision mechanism of legal system of use of police weapons. Chapter 7 Conclusion and Suggestion- It summarized findings of the research and set forth personal suggestions based on them for reference

Habitat Use of Six Skinks in Southern Taiwan

Zhu, Houng-Da 10 September 2002 (has links)
This study was conducted at Shuang-Yuan bridge (the border between Kaoshiung County and Ping-Tung County) and another four areas of Tai-Wu region at Ping-Tung County from June to August, 2000 and January to December, 2001. The main purpose of this research was to investigat the habitat use among sympatric skinks. During the research period, I discovered six species of skinks, including Eumeces elegans, Mabuya longicaudata, M. multifasciata, Scincella formosensis, Sphenomorphus incognitus and S. indicus. At Shuang-Yuan bridge, the habitat use among Mabuya longicaudata and Mabuya multifasciata differed significantly. Mabuya multifasciata was most common in open area, but Mabuya longicaudata was found mostly in close area, based on their habitat preference. Sphenomorphus incognitus and Sphenomorphus indicus were found in sympatry in low altitude area and their habitat use were similar, but in higher altitude region the habitat use differed considerably among two species, Sphenomorphus incognitus was more common in open area. Eumeces elegans was rare at three lower altitude regions in Tai-Wu, but more common at higher region and the habitat use was significantly different to that of Sphenomorphus indicus. Sphenomorphus indicus was found mainly in the ditch and water pipe, while Eumeces elegans was strongly associated with grass and rocks. Scincella formosensis was rare relatively among six skinks and preferred grass and leaf-litter.
