Sexual selections in the northern fall field cricket, Gryllus pennsylvanicus: a manipulation of the adult sex ratio

The operational sex ratio has long been considered an important constraint on the structure of mating systems. The effects of an experimentally manipulated sex ratio on mating behavior and selection were investigated in a polygynous species, Gryllus pennsylvanicus, where the potential exists for spatial/temporal fluctuations in sex ratio of field populations. Four different sex ratios (males: females, 5:0, 5:2, 5:5, 5:10) were investigated. Observations were conducted in late summer over two field seasons, from 2400 h , to 1000 h EST. Several male characters thought to be associated with male reproduc.tive success were studied: calling duration, searching distance, weight, fighting behavior, courtship frequency, and mating success. Variance in male mating success was used as the indicator for the opportunity for sexual selection. Total selection was estimated as the univariate regression coefficient between relative fitness and the character of interest, while direct selection was estimated as standardized partial regression coefficients generated from a multiple regression of relative fitness on each character. The opportunity for sexual selection was highest at 5:2 and lowest at 5:10. The frequency of fighting behavior was highest at 5:2 and 5:5. Fighting ability (% wins) was determined to be an important correlate of male body weight. Direct selection for increased male body weight was detected at 5:2, while total selection for body weight was seen at 5:5. Selection on male body weight was not detected at 5: 10. Calling duration decreased as sex ratio became more female-biased. Total and direct selection were detected for increased calling at 5:2, only total selection for calling was seen at 5:5, whereas direct selection against calling was detected at 5: 10. Searching distance also decreased as sex ratio became more female-biased, however no form of selection was detected for searching at any of the sex ratios. Data are discussed in terms of sexual selection on male reproductive tactics, the mating system and maintenance of genetic variation in male reproductive behavior.

Mothers' experiences in the elementary school education of their children of mixed heritage /

This study explores the perceptions and experiences of middle-class women, mostly mothers, regarding the elementary school education of their children of mixed heritage. Because it endeavours to provide a forum in which the voices of women are considered a source of valuable information for educators, this study contributes to the fields of feminist and mothering research. Participants assign meanings to their lived experiences (Schon, 1983; van Manen 1997) and contemplate the various ways in which a mixed heritage mayor may not affect a child's schooling. Four main participants were interviewed who are mothers whose children of mixed heritage presently attend public elementary schools in Ontario, Canada. The study had an emergent design, thus allowing the researcher to make decisions as the study progressed. Three additional participants were included in the study to provide a wider perspective on the topic. These 3 additional women were the researcher herself as she explored her self-conceptual baggage (Kirby & McKenna. 1989); the researcher's mother in an attempt to consider the motherline (Lowinsky, 1992); and a volunteer non-mother of mixed ethnicity. The study involved a total of 12 individual interviews of approximately 2 hours in length. The 4 main participants and the researcher were each interviewed twice; the researcher's mother and the volunteer non-mother were each interviewed once. The researcher also attempted a focus group and kept a journal throughout the research process. Much of the analysis centers on women's interpretations of the mixed heritage experience and on their suggestions for elementary school educators. It concludes pondering on the invisibility (Chiong, 1998) of such children within the school system and calling for increased teacher education as a way to bring the mixed heritage experience out of the shadows.

From absolutes to aesthetics : John Dewey and the art of experience /

In this thesis I sought to capture something of the integrity of John Dewey's larger vision. While recognizing this to be a difficult challenge, I needed to clear some of the debris of an overly narrow reading of Dewey's works by students of education. The tendency of reducing Dewey's larger philosophical vision down to neat theoretical snap shots in order to prop up their particular social scientific research, was in my estimation slowly damaging the larger integrity of Dewey's vast body of work. It was, in short, killing off the desire to read big works, because doing so was not necessary to satisfying the specialized interests of social scientific research. In this thesis then I made a plea for returning the Humanities to the center of higher education. It is there that students learn how to read and to think—skills required to take on someone of Dewey's stature. I set out in this thesis to do just that. I took Dewey's notion of experience as the main thread connecting all of his philosophy, and focused on two large areas of inquiry, science and its relation to philosophy, and aesthetic experience. By exploring in depth Dewey's understanding of human experience as it pertains to day-to-day living, my call was for a heightened mode of artful conduct within our living contexts. By calling on the necessity of appreciating the more qualitative dimensions of lived experience, I was hoping that students engaged in the Social Sciences might begin to bolster their research interests with more breadth and depth of reading and critical insight. I expressed this as being important to the survival and intelligent flourishing of democratic conduct.

The Development of a Survey to Assess the Type of Capacity within Nonprofit Sport Organizations

The topic of organizational capacity and organizational capacity-building has gained importance among Canadian nonprofit sport organizations. This is illustrated by practitioners calling for increased attention to the capacity-building matters of nonprofit organizations, and two critical Canadian federal government documents outlining strategic direction for the nonprofit sport sector. Consequently, the purpose of this quantitative research study was to develop a valid and reliable survey to categorize nonprofit sport organizations into capacity types identified by Stevens (Stevens, 2006). This quantitative research study offers a preliminary development towards achieving a reliable and valid tool for assessing types of nonprofit sport organizational capacity. This research provides interesting insight into what capacity means by organizing the all-encompassing literature into an easy to understand framework. In addition, it sets the stage for future researchers to build upon this survey development process to achieve a reliable and valid capacity measuring tool.

Average White Band poster, ca. 2000

The Average White Band's debut album, Show your hand, was released in 1973. The "classic funk and R & B" band included members Alan Gorrie, Owen "Onnie" McIntyre, Malcolm "Mollie" Duncan, Roger Ball, Robbie McIntosh, and Mike Rosen. Rosen was quickly replaced by Hamish Stuart. The band, comprised of Scotsmen, released a second album in 1974 that featured the US number 1/UK Top 10 single "Pick up the Pieces". That same year, Robbie McIntosh died of a heroin overdose and was replaced by Steve Ferrone. The song "Cut the Cake" from their third album made the US top 10, and subsequent releases in the late 1970s and early 1980s proved successful. The members largely pursued individual projects in the years that followed, but re-formed in 1989 (with original members Gorrie, Ball and McIntyre, and new members Alex Ligertwood and Eliot Lewis) and released the album Aftershock. Over the years, the band's members have changed, and the band is currently comprised of Onnie McIntyre, Rocky Bryant, Alan Gorrie, Fred "Freddy V" Vigdor and Klyde Jones. Their most recent album, Times Squared, was released in 2009.

In Search of Convergence: A Co-citation Analysis of Three Sport Management Journals

Responding to a series of articles in sport management literature calling for more diversity in terms of areas of interest or methods, this study warns against the danger of excessively fragmenting this field of research. The works of Kuhn (1962) and Pfeffer (1993) are taken as the basis of an argument that connects convergence with scientific strength. However, being aware of the large number of counterarguments directed at this line of reasoning, a new model of convergence, which focuses on clusters of research contributions with similar areas of interest, methods, and concepts, is proposed. The existence of these clusters is determined with the help of a bibliometric analysis of publications in three sport management journals. This examination determines that there are justified reasons to be concerned about the level of convergence in the field, pointing out to a reduced ability to create large clusters of contributions in similar areas of interest.

Entering Youthwork Through Love's Many Pathways: A Poetic Rendition

Entering Youth work Through Love's Many Pathways is a text that wanders and digresses to places where, through poetic inquiry and a Spinozist and Sufi framework, the concepts of immanence, love and becoming can be explored. This thesis is framed as a walk through which the researcher / youth worker along with the reader, traverses through five pathways that she considers necessary in cultivating a meaningful relationship with the youth: opening, strength, listening, trust and unconditional compassion. By means of engaging the “self”, this thesis approaches youth work as a field that is relational and socially interconnected. In this sense, this poetic inquiry seeks to rupture predictable patterns of behaviour. One of the ways I do this is through found poetry. Through this specific form of poetic inquiry, I bring together various voices, an assemblage – Rumi, Rilke, Whitman, Lalla, Mirabai and Song of Songs – in order to find my voice and by extension, to help the youth find their voice through a human connection that goes beyond colour, race, gender etc. In other words, my aim is to actualize the experiences of becoming youth worker while being in a field of immanence where similarities are understood and differences respected. My hope is that this project may offer an example of understanding, celebration, and engagement of our mutual differences, while still being able to relate to one another through the many pathways of love.

Humour and Learning: A Self-Study of My Practice as an Adult Educator

This study examined my lived experiences as a frontline practitioner and adult educator in a local nonprofit community organization. Using self-study research methodology, I explored my professional practice as a facilitator of job search skills training with newcomers to Canada and the impact of humour on their learning, a topic for which I have a particular passion. To better inform my practice, I designed and delivered job search skills workshops on resume writing and cold-calling/networking. I used a variety of data sources including a literature review, personal observations, and reflections as well as secondary data sources from workshop evaluations and unsolicited feedback emails from participants. Findings from the self-study indicated that adult learners who experience entertaining and fun-filled lessons that use appropriate humour have better learning results, are more confident, and are better prepared to apply skills required for achieving career goals. Further, I learned in my practice that my challenge as an adult educator is to ensure humour is appropriately used and adds value to the learning rather than being the focus of the teaching.

The Role of Orexin-A in Anxiety and the Emission of Ultrasonic Vocalizations in Rats

Central administration of orexin-A has been shown to activate autonomic arousal in rats, reliably inducing anxiety-like behaviours in the open field. To date, there has yet to be a study investigating the role of orexin-A in the communication of such negative affective state. In the current study, forty-six adult male rats were chronically cannulated and administered orexin-A into the medial preoptic area/anterior hypothalamic area to determine the effect of this neuropeptide on anxiety-like behaviour and the production of 22 kHz aversive ultrasonic vocalizations. It was found that intracerebral administration of orexin-A increased autonomic arousal as measured by a significant increase in fecal boli output, however orexin-A did not significantly affect locomotor activity or induce 22 kHz calling. These data suggest that orexin-A is involved in the regulation of the autonomic aspect of anxiety-like behaviour but not in the vocal communication of such negative affect

Andrew Bloomfield collection, 2006-2012

Andrew Bloomfield, and his twin sister Victoria, were born on May 6, 1968 in Auckland, New Zealand. The following year, the family moved to Guelph, Ontario. It became apparent from the time Andrew was 14 months old that he differed considerably from his twin sister, and he was subsequently diagnosed with autism when he was four years old. As a result, he lived away from his family for much of his early life in order to participate in programs for autistic people. Andrew found this very difficult, but also made some significant progress. He became able to relate to and care for his dog, and was able to express his thoughts with Augmentative and Alternative Communication, especially using Supported Typing. His twin sister Victoria was an important person in his life, and her untimely death in a car accident in 1996 devastated him. However, his network of friends and family have provided immense support and helped him build a fulfilling and meaningful life. In 2004 Andrew founded a group of other adult communicators who "type to talk" which he named "Bridges-Over-Barriers". They meet monthly in Guelph and contributed to the 2010 volume with accompanying documentary film on DVD. He lives in his own home in Guelph, guaranteed by a housing trust, and has written several books, including an autobiography, Bridges over Barriers in My Life with Autism.

Investigation of the role of the nucleus accumbens in amphetamine-induced 50 kHz ultrasonic vocalizations in the rat

There is extensive evidence that the mesolimbic dopamine system underlies the production of 50 kHz ultrasonic vocalizations in rats. In particular, the shell of the nucleus accumbens is associated with generation of frequency modulated 50 kHz calls (a specific type of 50 kHz call which can be subdivided into various subtypes). There is also evidence that amphetamine administered systemically preferentially increases the proportion of trill and step calls compared to other frequency modulated 50 kHz subtypes. The purpose of this study was to investigate the effect of drug administration route and the role of the nucleus accumbens shell in amphetamine-induced 50 kHz call profile in the rat. Three experiments investigated this by using subcutaneous and intra-accumbens microinjections of amphetamine, as well as procaine (a local anesthetic) blockade of the nucleus accumbens. Ultrasonic vocalizations were recorded digitally from 24 rats and were analysed for sonographic structure based on general call parameters. The results of the three experiments were partially supportive of the hypotheses. Systemic amphetamine was found to induce greater bandwidth in 50 kHz calling compared to spontaneous calls in a vehicle condition. Systemic amphetamine was also found to preferentially increase the proportion of trill and step subtypes compared to vehicle. Moreover, there was no difference in the proportions of 50 kHz subtypes resulting from intracerebral or systemic application of amphetamine. There was, however, a significant difference for bandwidth, with systemic amphetamine inducing greater bandwidth over intraaccumbens application. Procaine blockade of the nucleus accumbens shell paired with subcutaneous amphetamine produced no difference in bandwidth of calls compared with those after a vehicle pre-treatment similarly paired. There was no reduction in the proportions of trill and step 50 kHz subtypes as well, with the procaine condition showing significantly greater proportion of step calls. The results of the study support a role for the iii nucleus accumbens shell in the amphetamine-induced changes on 50 kHz call profile. They also indicate there are more regions and pathways involved in generating 50 kHz calls than the projections from the ventral tegmental area to the nucleus accumbens. The implications of this work are that frequency modulated 50 kHz subtypes may be generated by distinct neurophysiological mechanisms and may represent a profitable avenue for investigating different circuits of 50 kHz call categories in the rat.
