The benefits gained by the presentation of environmental enrichment (EE) to captive animals are widely recognized. Few studies have, however, studied how to maximize the effect of EE. Repeated presentations of EE may cause a reduced interest towards the EE device, called habituation. To study the effect of habituation towards EE, behavioural data from 14 captive Sloth bears (Melursus ursinus) were collected during two different EE treatments. In treatment one, honey logs were presented for five consecutive days (ConsEE). In treatment two, the logs were presented every alternative day for five days (AltEE). The different treatments both showed a significant effect on responsiveness toward the EE, however, leaving gap days inbetween presentations in AltEE showed no reliable reduction in habituation. Both treatments significantly reduced stereotypies, however, only ConsEE reduced levels of stereotypies long term. Explorative behaviours, which are the most prominent behaviours in the wild, increased during both treatments. This is consistent with previous findings (Fischbacher & Schmid 1999, Grandia et al. 2001) that EE increases natural behaviours, which has been desribed as an indication of improved welfare (Carlstead et al. 1991 etc.). Other behavioural categories such as social and passiva behaviours were unaffected by the EE presentations. THe results show that it is possible to increase the effectiveness of EE by simple means in order to ensure animal welfare.

In the 21st century, the mobility of world population has posed greater challenges to healthcare practitioners, since they are facing an increasingly diverse patient population from all over the world. At the same time, patients also find it difficult to access and utilize quality health care services in a culturally diverse context. This study examines the role of culture in Chinese international students’ health-seeking behaviours in Canada. The study explores any barriers/perceived barriers that Chinese international students may confront when accessing health care which can prevent them from obtaining quality health care services in Canada. To this end, an intercultural health communication model was employed as a theoretical framework, and semi-structured interviews were used as a data collection tool. While contributing to existing literature on health communication and culture, this study also hopes to contribute to providing Canadian universities and institutions important information regarding Chinese international students’ access to and utilization of health care services with the hope of enhancing the quality of ethnic health care and promoting better health outcomes.

Background: Pregnancy has been described as a period when women experience heightened behavioural surveillance. Young single women have commonly been described as a population who engage in high risk behaviours during pregnancy (e.g. smoking), yet they are also a population who often has access to fewer resources to make expected behaviour changes during pregnancy. Purpose: To explore the experiences of young single pregnant and parenting women regarding behavioural expectations and behaviour change during pregnancy. Research Questions: (1) What are the perceived behavioural expectations for young single women during pregnancy? (2) Who or what reinforces the perceived behavioural expectations? (3) To which behavioural expectations do young single women conform (or resist) and why? Methods: Nine single pregnant or parenting women between the ages of 15 and 24 were recruited from two urban community health settings between November 2011 and January 2012. Data was collected through individual semi-structured photo-elicitation interviews and analyzed using qualitative content analysis. Results: The main findings of the study include: (1) young single pregnant women are subject to a multitude of health and social behavioural expectations, (2) young single women experience internal and external behavioural surveillance during pregnancy, and (3) young single pregnant women experience these behavioural expectations as a tension between the potential for opportunity and oppression. Implications for Practice: By understanding young single pregnant women’s perceptions of how they are expected to behave, who and what reinforces such expectations, and how young women conform to or resist such expectations, the results of this project will inform the development of effective individual, community, and systemic level interventions and better inform interactions with young pregnant women.

<p>This study is aimed at empirically examining health seeking behaviours in terms of illness response on household level at South Africa using 2007 General Household Survey and other<br /> relevant secondary sources. It provides an assessment of health seeking behaviours at the household level using individuals as unit of analysis by exploring the type of health care provider sought, the reason for delay in health seeking and the cause for not consulting. This study also assesses the extent of dissatisfaction among households using medical centres and this factor in health care utilisation is considered as the main reason for not consulting health care services. All the demographic and health seeking variables utilised in this study are controlled for medical aid cover because it is a critical variable in health care seeking. Therefore this study makes distinction on illness reporting and they type of health care consulted by medical aid holders and non medical aid holders. Statistical analyses are conducted to explore and predict the way in which demographic variables and socio economic variables affect health care seeking behaviours.</p>

Urban centers and smaller communities across Canada are witnessing an increase in youth gang activity. But, determining both the level and nature of youth gang involvement/activity is problematic, in part because of varied interpretations of what it means to be a gang. Many Canadians believe that a gang is a structured organization with crime as their main objective. However, youth gangs can range from associations involving a loosely organized collective of friends that come together to protect their neighborhood to that of the hardcore gangs who have political agendas and are structurally organized. It is much more difficult to determine the level and nature of youth gang activity because they are ever changing entities depending on factors such as race, socio-economic status, and community. Youth gangs become a burden to society financially, emotionally, and mentally. Costs are incurred due to vandalism and an increase in crime: while anguish and a heightened sense of fear/anxiety speak to the emotional, mental, and spiritual aspects resulting from gang activities.<p> This study is a qualitative analysis that focuses on how agencies in Saskatoon define youth gang activities and behaviors. The agencies involved constitute community based organizations, permanent and part-time holding residences, justice and city officials. Grounded theory analysis was utilized to maintain the original interviewees own voices from interviews to the final product. The final analysis is divided into three sections that focus on: characteristics of Saskatoon youth gangs, implications of defining, and programming. By analyzing these themes we begin to see that defining youth gangs becomes a very political issue and that agencies who work with youth have difficulty in coming to terms in creating a common definition of youth gangs for Saskatoon.

Northern environments are often characterised by large seasonal and annual fluctuations in food abundance. In this thesis, I examined how arctic foxes (</i>Alopex lagopus</i>) used seasonally superabundant foods (geese and their eggs) and how access to these foods influenced population dynamics of arctic foxes. I addressed this against a backdrop of variation in lemming and vole abundance (small mammals hereafter) the main foods of arctic foxes throughout most of their range. Field work was done at the large goose colony at Karrak Lake and surrounding areas in the Queen Maud Gulf Bird Sanctuary in Nunavut, Canada, in the spring and summers of 2000 to 2004. <p> Behavioural observations of individually-marked arctic foxes showed that they took and cached 2,000-3,000 eggs per fox each year and that the rate at which they took eggs was largely unrelated to individual attributes of foxes (e.g. sex, size, and breeding status) and nesting distribution of geese. Further, the rate at which foxes took eggs varied considerably within individuals in that foxes were efficient at taking eggs at times and inefficient at other times. This may have resulted from foxes switching between foraging actively and taking eggs opportunistically while performing other demands such as territorial behaviours. <p>Comparison of stable isotope ratios (13C and 15N) of fox tissues and those of their foods showed that the contribution of cached eggs to arctic fox diets was inversely related to collared lemming (<i>Dicrostonyx torquatus</i>) abundance. In fact, the contribution of cached eggs to overall fox diets increased from <28% in years when collared lemmings were abundant to 30-74% in years when collared lemmings were scarce. Furthermore, arctic foxes used cached eggs well into the following spring (almost 1 year after eggs were acquired) a pattern which differs from that of carnivores generally storing foods for only a few days before consumption. <p>A field-study of experimental caches showed that survival rate of these caches was related to age of cache sites in the first year of the study (e.g. 0.80 and 0.56 per 18-day period for caches from new and 1 month old cache sites, respectively) and departure by geese after hatch in the second year of the study (e.g. 0.98 and 0.74 per 18-day period during and after goose nesting, respectively). Food abundance and deterioration of cache sites (e.g. loss of soil cover and partial exposure of caches) were, thus, important factors affecting cache loss at Karrak Lake. Further, annual variation in the importance of these factors suggests that strategies to prevent cache loss are not fixed in time but vary with existing conditions. Evolution of caching behaviours by arctic foxes may, thus, have been shaped by multiple selective pressures. <p>Comparisons of reproductive output and abundance of arctic foxes inside and outside the goose colony at Karrak Lake showed that (i) breeding density and fox abundance were 2-3 times higher inside the colony than they were outside the colony and (ii) litter size, breeding density, and annual variation in fox abundance followed that of small mammal abundance. Small mammal abundance was, thus, the main governor of population dynamics of arctic foxes whereas geese and their eggs elevated fox abundance and breeding density above that which small mammals could support. These results highlight both the influence of seasonal and annual variation on population dynamics of consumers and the linkage between arctic environments and wintering areas by geese thousands of kilometres to the south.

As much of the growing population of North America is accommodated within cities or on their fringes, one needs to understand how these people are managing their private outdoor space. Within the cities of Kitchener and Waterloo, Ontario, Canada a randomly selected set of residential occupancies were surveyed in 1994 and 2004 about their yard landscaping and maintenance practices. Parallel mail-out questionnaires were delivered to more than 1,000 randomly selected addresses in both 1994 and 2004. Approximately 30 percent of surveyed occupancies completed the questionnaire in both years. Over one-third of respondents from both 1994 and 2004 were matched together based on individual, household, or address information. The matched respondent results were used to validate similarities and identify any inconsistencies between survey years. In general, matched respondent trends did not differ substantially from the overall study trends. <br /><br /> This study found that much of the outdoor space on residential properties consists of turfgrass lawn. Lawns were the dominant form of landscaping in both 1994 and 2004. Although respondents' attitudes towards lawns shifted slightly in favour of more gardens in the 2004 survey compared to 1994, respondents' actual landscaping styles and behaviours did not follow suit. Regardless of minor differences in attitudes between survey years, turfgrass was reported to be present in more than 85 percent of respondents' yards. On average, lawns were estimated to cover more than half of respondents' total private outdoor space in both 1994 and 2004. Likewise, more than 60 percent of respondents in both survey years indicated that their yard reflected a monoculture lawn. When compared with five other styles of landscaping, the monoculture lawn was found attractive and well-liked by approximately half the respondents in both survey years. In addition to the prevalence and preference for lawns, lawns were seen as practical to maintain as: the majority of respondents had a lawnmower ? mostly gas-powered; respondents were willing to spend almost $200 a year to water their lawn, on average; the application of chemicals, particularly fertilizers, was common with approximately half the respondents; and more than 40 percent of respondents were willing to pay lawn-care professionals to look after their yards. Lawns were also perceived to be the landscaping style most acceptable to neighbours. Thus, given the ubiquitousness of lawns in urban residential environments, the presence of lawns not only represents the yard design preferences of homeowners, but is part of deeply entrenched societal norms. <br /><br /> With assistance from the media and advertisements, these implicit societal norms were found to influence household attitudes and preferences towards what is dubbed 'lawn-scaping'. As confirmation of these subtle norms, more than 60 percent of respondents in both survey years agreed that 'a yard has to have a lawn'. However, these landscaping norms are also explicitly established in municipal property regulations and lot-maintenance by-laws. Hence, the lawn landscape is implicitly linked with social norms and explicitly articulated in legal agreements, making it the unquestioned standard of landscaping styles. It is concluded that a change in local policies and regulations, along with greater education and awareness, will lay the foundation for more alternative styles of landscaping within urban residential areas.

Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides information at a distance for proactively controlling locomotion (Gibson, 1958). The visual system provides information about self-motion, about body position and body segments relative to one another and the environment, and environmental information at a distance (Patla, 1998). Gibson (1979) developed the idea that everyday behaviour is controlled by perception-action coupling between an action and some specific information picked up from the optic flow that is generated by that action. Such that visual perception guides the action required to navigate safely through an environment and the action in turn alters perception. The objective of my thesis was to determine how well perception and action are coupled when approaching and walking through moving doors with dynamically changing apertures. My first two studies were grouped together and here I found that as the level of threat increased, the parameters of control changed and not the controlling mechanism. The two dominant action control parameters observed were a change in approach velocity and a change in posture (i. e. shoulder rotation). These findings add to previous work done in this area using a similar set-up in virtual reality, where after much practice participants increased success rate by decreasing velocity prior to crossing the doors. In my third study I found that visual fixation patterns and action parameters were similar when the location of the aperture was predictable and when it was not. Previous work from other researchers has shown that vision and a subsequent action are tightly coupled with a latency of about 1second. I have found that vision only tightly couples action when a specific action is required and the threat of a collision increases. My findings also point in the same direction as previous work that has shown that individuals look where they are going. My last study was designed to determine if we go where we are looking. Here I found that action does follow vision but is only loosely correlated. The most important and common finding from all the studies is that at 2 seconds prior to crossing the moving doors (any type of movement) vision seems to have the most profound effect on action. At this time variability in action is significantly lower than at prior times. I believe that my findings will help to understand how individuals use vision to modify actions in order to avoid colliding with other people or other moving objects within the environment. And this knowledge will help elderly individuals to be better able to cope with walking in cluttered environments and avoid contacting other objects.
