Examining the potential application of childhood stature in assessing adolescent overweight and obesity

Background: Increasing Overweight and Obesity (OwOb) prevalence in pediatric populations is becoming a public health concern in many countries. The purpose of this study was to determine if childhood stature components, particularly the Leg Length Index (LLI = [height - sitting height]! height), were useful in assessing risk of OwOb in adolescence. Methods: Data was from a longitudinal study conducted in south Ontario since 2004. Approximately 2360 students had body composition measurements including sitting height and standing height at baseline. Among them, 1167 children (573 girls, 594 boys) who had weight and height measured at the 5 th year follow-up, were included in this analysis. OwOb was defined using age and sex specific BMI (kg!m 2 ) cut-off points corresponding to adults' BMI ~ 25. Results: Overall, 34% (n=298) of adolescents were considered as OwOb. The results from logistic regression analysis indicated that with 1 unit increase in LLI the odds of OwOb decreased 24% (Odds Ratio, [95% Confidence Interval], 0.76, [0.66-0.87]) after adjusted for age, sex and baseline waist circumference. Further adjusting for birth weight, birth order, breastfeeding, child's physical activity, maternal smoking, education, mother's age at birth and mother's BMI, did not change the relationship. Our results also indicated that mother's smoking status is associated with LLI. Discussion: Although LLI measured at childhood in this study is related to OwOb risk in adolescents, the underlying mechanism is unclear and further study is needed.

Back to School, Back to Normal? Exploring the Lived Experiences of Childhood Cancer Survivors and their Families Throughout the School Re-Entry Process

This study investigated parent and child perspectives of childhood cancer survivors' return to school. Four specific areas were examined including cognitive and academic concerns, social issues, perceived support, and the impact on siblings. Participants consisted of parents and childhood cancer survivors who were recruited through a regional parent support group. Data was collected during a focus group and interviews. Using a descriptive content analysis, results indicated that participants generally received the necessary resources, however issues such as consistency and having to advocate in order to attain these resources served as barriers for the families.

A discursive analysis of children's recreational adult-organized sport : when do children get to play?

Adult-organized children's sport attracts millions of participants in Canada and the United States each year. Though there is a great deal of research that considers children's sport, little of it focuses on recreational or house league sport and less of it offers a deep examination of children's experience of their participation. Using observations, interviews, and focus groups involving ten participants in mixed-gender recreational basketball, this qualitative research project examined their experiences. With Foucault's concepts of correct training and the panoptic gaze in mind, I used discourse and deconstruction analyses to consider the children's descriptions along with my observations of their basketball experience. I was particularly looking for prevalent discourses on sport, childhood, and gender and how they affected their experiences. Despite the league's discursive emphasis on fun, participation, fairness, and respect, that was not necessarily what the children experienced. While most stated they enjoyed their season many also expressed serious disappointments. Size and particularly skill very much determined who was most involved in the action and thus actually played baskethaW. Gender also played a significant role in their sport experiences. My findings invite questions about what genuine sport participation actually is and how it might be alternatively imagined.

In distrust we trust : analysis of academic apocalypse

The paper concentrates on trust as a research topic that receives increasing attention from the side of different social disciplines. The author of this thesis attempts to identify the reasons of this phenomenon, as well as the decline in usage of the concepts conveying a congenial idea, such as, solidarity, cooperation, social cohesion, social capital or connectedness. The key hypotheses, such as paradigmatic change within the social sciences, emergence of risk society, proliferation of the postmodem condition, new infonnation and communication technologies and the crisis of democracy are considered through the works of the authors who now mainly responsible for the shaping of the discourse of trust. The concepts of Luhmann, Putnam, Sztompka, Fukuyama and Hardin are analyzed from an epistemological viewpoint in its ontological and political implications. The primary goal of the paper is to overview trust from the methodological viewpoint, illustrating the limitations of the concept as a research strategy as weII as it advantages in the epoch when the social sciences acquire a status of moral disciplines.

A qualitative study of authority from the perspective of secondary school principals /

In this research study I examined how four principals of secondary schools interpreted authority and how these interpretations affected their practice. This study involved a presentation of the literature where the concept of qualitative methodology as well as general concepts of authority were reviewed. Four principals were interviewed and asked to reflect on their feelings and experiences as they related to the practice of authority. Five major themes emerged from their reflections and stories which were: Understandings of the Concept of Authority, Principals' Enactment of Authority, Thoughts and Experiences related to Challenges to Their Authority, A View of Principals' Challenge of Authority, and Changing Views on the Authority of Principals in Ontario. The stories of these four principals demonstrated that the practice of authority is complex, dynamic, and contains personal and social tensions. The sharing of these ideas and stories provided a window into the world of these secondary school educational leaders and their experiences with, and enactment of, authority. From this research four recommendations were made to improve educators' practice related to the issue of authority. The importance of this study is that it presents an understanding of the dynamic nature of the process and enactment of authority by these secondary school principals at a unique time in the history of education in Ontario.This qualitative research provides a snapshot of a particular group of educators at a particular time and place. Others need to add to these understandings and modify these ideas through further research. Understanding the experiences of educational leaders as they negotiate concepts of authority gives a window on this very complex, yet vital, component of education.

Research in the clinical setting : a qualitative study of the value of play research in the continuing education of occupational therapists.

Occupational therapists have always recognized playas an important part of a child's life. However, until recently play has been viewed as a medium for reaching treatment goals, rather than as an activity that is valuable in and of itself. If occupational therapists think of playas the primary activity or occupation of childhood, then play should be a very important area of focus for paediatric clinicians. In order to assist children to become as independent as possible with play and to have fulfilling play experiences the occupational therapist needs to have a clear understanding of how to assess, set goals which lead towards competence in play, and promote play. Recent play literature has placed importance on play behaviours and looking at the relationship between the child and both the human and nonhuman environment. Believing that play and playfulness can and should be promoted, for children with physical disabilities, requires that therapists learn new assessment and intervention strategies. A new assessment tool, The Test of Playfulness, was developed by Bundy in 1994. It addressed play behaviours and environmental influences. The author, a co-investigator and eight occupational therapists were involved in a playfulness study using this test to compare the playfulness of children with physical disabilities with their able-bodied peers. After the study was completed the author questioned whether or not involvement in the playfulness study was enough of a change agent to bring about transformative learning in order to further the eight occupational therapists' education about play.This study investigated changes in either the therapists' thinking about play or their behaviour in their clinical practice. The study also examined the participants' retention of knowledge about the Test of Playfulness. The eight therapists who had been involved in the playfulness study (participants) were matched with eight therapists who had not been involved (nonparticipants). The therapists were interviewed 9 to 12 months after completion of the playfulness study. They were asked to describe various scenarios of play and open ended prompts were used to elicit the therapists' perceptions of play, good play, the role or value of play, environmental and gender influences on play, play assessment and intervention, and play research, for children with and without disabilities. The participants were also prompted to discuss their experience with the playfulness study. A self-report questionnaire was also completed at the end of the interview. The results of the study demonstrated that: (a) the play research project was a good format for continuing the participants' education about play; (b) their thinking had changed about play; (c) according to self report, they had used this new knowledge in their clinical practice; and (d) the participants remembered the items on the Test of Playfulness and could use them in describing various aspects of play. This study found that participating in a play research project had been an effective method of professional development. It also highlighted the need for increased awareness of the recent literature on play and the developing role of the occupational therapist in the assessment and intervention of play.

Desire and the paths of recognation [sic] in Hegel's intersubjectivity

This thesis poses two fundamental issues regarding Hegel's philosophy of intersubjectivity. Firstly, it examines Kojeve's problematic interpretation of Hegelian intersubjectivity as being solely rooted in the dialectic of lordship and bondage. It is my contention that Kojeve conflates the concepts of recognition {Anerkennung) with that of desire (Begierde), thereby reducing Hegel's philosophy of intersubjectivity to a violent reduction of the other to the same. This is so despite the plenary of examples Hegel uses to define intersubjectivity as the mutual (reciprocal) recognition between the self and the other. Secondly, it examines Hegel's use of Sophocles' Antigone to demonstrate the notion of the individual par excellence. I contend that Hegel's use of Antigone opens a new methodological framework through which to view his philosophy of intersubjectivity. It is Antigone that demonstrates the upheaval of an economy of exchange between the self and the other, whereby the alterity of the other transcends the self Ultimately, Hegel's philosophy of intersubjectivity must be reexamined, not only to dismiss Kojeve's problematic interpretation, but also to pose the possibility that Hegel's philosophy of intersubjectivity can viably account for a philosophy of the other that has a voice in contemporary philosophical debate.

Prevalence of overweight and obesity in children from urban and rural Niagara

Purpose: The influence of environment in the development of overweight and obesity is an ongoing concern. This investigation examined the influence of urbanization on the rates of childhood overweight and obesity. Method: 2167 (1090M, 1077F) grade four children from 75 schools in Ontario's Niagara Region were sampled. A sophisticated algorithm overlaying electoral boundaries, population densities, and the knowledge of community members was used to classify schools into one of three location categories: urban {N= 1588), urban fringe {N= 379), and rural (A^= 234). Each subject was measured for: height, weight, and aerobic performance (Leger). Physical activity was evaluated with the self-report Participation Questionnaire (free-time and organized sport activities), and teacher's evaluations of student activity. Overweight (overweight and obesity combined) was measured both as a continuous (BMI) and categorical variable (BMI category), to evaluate the prevalence by location. A multivariate analysis was used to test for a suppression effect. Results: BMI and BMI category did not differ significantly by location or gender, and no evidence of a gender interaction existed. According to both a linear and logistic regression, physical activity or fitness levels did not suppress the influence of location on BMI and BMI category. Age, gender, free-time activity, organized sports, fitness level, and number of siblings, were all found to significantly influence overweight. Conclusions: It is plausible that the prevalence of overweight does not differ in urban and rural children from the Niagara Region. Further investigation is recommended, examining subjects by individual location of residence, in multiple regions throughout Ontario.

A mass spectrometric study of some pesticides /|nK. S. Subramanian. -- 260 St. Catharines, Ont. : [s. n.],

The fragmentation processes in the mass spectra of a series of organophosphorus, organochlorine, thio and dithiocarbamate as well as a number of miscellaneous pesticides have been studied i n detail by using the Bendix timeof- flight, MS-12 single-focussing and MS-30 double-focussing mass spectrometers. Interpretation of all the spectra have been presented; their mode s of dissociation elucidated, aided by metastable transitions wherever possible and the structures of the various f ragmentation species postulated wherever f easible. The fragmentation mechanisms are based on the concepts of inductive, resonance and steric ef~ects. Multiple bond cleavages accompanied by simultaneous bond formation and rearrangement reactions involving cycli c t r ansition states have clarified t he formation of various ions . Due emphasis has been placed on the effect of the functional groups or substituents in altering the mass spectral behaviour of the pesticides as they form the basis for the identifi cation of the otherwise identical pesticides. The organophosphorus pesticides which have been studied include i) the phosphates (eg: DDVP and Phosdrin ); ii) phosphorothionates (eg: Parathion, 0-2, 4 dichloro phenyl 0, O-diethyl thionophosphate); iii) phosphorothioites (eg: Tributyl phosphorotrithioite); i V) phosphorothioates (eg: Ethion) and v) phosphorodithioates (eg: Carbophenolthion). Cleavages and rearrangements of the ester moiety dominate the spectrum of phosdrin while that of DDVP is + dominated by t he fragmentation modes of the (OH30)2P=0 + moiety. Fragmentation §f the (CH30)2P=S characterises the spectrum of (OH30)2"P -Cl while cleavages of the + (C2H50 )2P=S species mark the spectra of parathion and 0-2, 4- di chlorophenyl O, O-diethyl thiophosphate. The 0(, cl eavages of the thioether f unction rather than + cleavages of the (C2H50)2P=S signify the spectrum of carbophenolthion. Tributyl phosphorotrithioite behaves more like an aliphatic hydrocarbon than like the corresponding phosphites. The isopropyl and butyl esters of 2, 4 dichlorophenoxy acetic acid show cleavage and rearrangement ions typical of an ester. In spite of its structural similari ty to pp' - DDT and pp' - DDD, Kalthane has a completely different mass spectral behaviour due to the influence of its hydroxyl function. The thiocarbamate pesticides studied include Eptam and Perbulate. Both are structurally similar but having different alkyl substituents on nitrogen and sulphur. This structurQlsimilarity leads to similar types of (N-C), (O-S) and (S-alkyl cleavages). However, perbulate differs from Eptam in showing a rearrangement ion at mle 161 and in forming an isocyanate ion as the base peak. In Eptam the base peak i s the alkyl ion. The dithiocarbamate, Vegadex, resembles the thiocarbamates in undergoing simple cleavages but it differs from them in having a weak parent ion; in the formation of its base peak and in undergoing a series of rearrangement reactions. The miscellaneous pesticides studied include 1-Naphthalene acetic aCid- methyl ester, Fiperonyl butoxide and Allethrin. The ester i s stable to electron impact and shows only fewer ions. Piper onyl butoxide, a polyether, shows characteristics of an et her, alcohol and aldehyde . Allethrin is regarded as an ester of the type R-C-O-R1 with n R being a substituted cyclopr opane moiety and o Rt, a substituted cyclopentenone mOiety. Accordingly it shows cleavage ions typical of an aliphatic ester and undergoes bond ruptures of the cyclic moieties to give unusual ions. Its base peak is an odd electron ion, quite contrary to expectations.

Children's rights and parenting beliefs : a study of attitudes, values and emotions

The conceptualization of childhood has changed over the centuries and appears to be undergoing further change in our post-modern culture. While the United Nations Convention on the Right of the Child is designed to give children everywhere basic human rights while taking into consideration their special needs, no recent research has examined adult attitudes toward those rights. In an attempt to understand the attitudes adults hold regarding autonomy rights and to look for some factors that could predict those attitudes, the current study considers values, parenting style, emotions and the issue of parent status as possible predictor variables. A total of 90 participants took part in the research, which had both written and interview components. Results generally failed to establish a reliable set of predictors. However, some interesting information was obtained regarding the endorsement of children's autonomy rights and some general conclusions were reached about our view of children and their rights at the end of the twentieth century.

Exploring the experience of the pioneers of change

The world of work with Western society appears to be undergoing a major change. The literature has described this phenomenon as a change from an industrialbased economy to a knowledge-based economy. This change will represent a complete transformation of the world of work; some suggest that everything we have come to accept and know as normal will change. Our present society seems to be in a period of transition. It is a time with many challenges and problems, many of which cannot be solved with thinking patterns from an old industrial-based economy. A fundamental shift in thinking patterns consistent with a new emerging world of work must take place. This change in thinking represents a fundmental shift from traditional and linear ways of seeing the world (worldview), to more holistic ways of seeing the world. In this investigation the word paradigm was used to define how people see their world. A paradigm shift is defined as a change in how a person sees their world: a change from an old to new or different way of viewing the world. Those individuals who are the first to shift their paradigm are called paradigm pioneers. These individuals do not only shift their ways of seeing the world, but they also begin to act and behave in ways consistent with the new paradigm. Thus far the research literature has adequately described the concepts of paradigms and paradigm shifts. However, little is known regarding how people actually and eventually make a shift. As it will be important for each individual to make a personal paradigm shift, then it will be extremely valuable to learn more about the process itself. The purpose of this investigation was to explore these issues in more detail and specifically, describe the experience of paradigm shifts and explore the experience of paradigm pioneers. A qualitative research methodology involving in-depth interviews was used to investigate the experiences of four participants identified as paradigm pioneers. It is interesting to note that the participants in this study did not describe an allencompassing paradigm shift. In fact, each participant, defined a paradigm shift in several different ways. They did relate several examples of paradigm shifts. However, even among these examples, there was a high degree of variability. The findings of this investigation centered upon the participants' experience as pioneers. Each pioneer shared many of the same qualities, the first quality of which described how these pioneers dealt with change. I called this a change-sense quality. The pioneers viewed change in an open and positive manner, and were also aware of change taking place in their world. Finally, they displayed an understanding of change, and a bias to take positive action in the face it. The participants also shared an inner quality. The four pioneers demonstrated a personal purpose and vision, and were selfdirected individuals. They also had an innate curiosity which translated into a love of learning. They also displayed a quality where relationships with others were highly valued. Relationships were important to the pioneers because they played a support role to help them deal with the challenges of being a pioneer. Pioneers also valued relationships because, they relied on others to make change happen. The above mentioned qualities enabled pioneers to be effective in a changing world of work. The findings from this investigation have many implications for research and practice. First, the concept of paradigms and paradigm shifts must be further researched. A great deal more must be learned in order to better understand the kind of shift individuals must make to be effective in the new world of work. Second, the qualities displayed by pioneers are important for all members of the world of work to develop. The qualities shared by pioneers appeared to represent an enduring set of traits that can possibly help individuals deal more positively with uncertainty and rapid change taking place in today's North American world of work.

Interdependence in Southern Africa: an examination of the relations between Zimbabwe and South Africa

Most research on southern Africa focuses on the total dependency of the region's states--Angola, Botswana, Lesotho, Malawi, Mozambique, Swaziland, zambia and Zimbabwe--upon the dominant power, South Africa. This thesis examines the relationship between South Africa and Zimbabwe and argues that these two states are more interdependent than dependency scholars would acknowledge. Although a study of the historical period reveals that dependency theory, as defined by Raul Prebisch, Andre Gunder Frank and A. Valenzuela, is helpful for understanding the development of relations between the two states, it is unable to account for many of the characteristics of the relationship which are found in the contemporary context, especially since 1980. An examination of various economic areas of interaction, including investment, trade and transportation, as well as the political realm, indicates that each state exhibits a degree of dependence upon the other. Thus, it is possible to characterize the relationship as one of "mutual dependence," or interdependence as defined by Robert Keohane and Joseph S. Nye. Interdependence is further examined through the concepts of sensitivity and vulnerability. Sensitivity signifies the ability of a state to respond effectively to policy changes made by another state wi thin a given area of interaction without incurring large costs, while vulnerability denotes that an actor is unable to respond, or only at great cost. By applying these concepts to the relationship between Zimbabwe and South Africa, it is determined that although South Africa tends to be sensitive while Zimbabwe is generally vulnerable, the degrees to which these two states are sensi ti ve and vulnerable varies over time and issue area. As the changes wi thin South Africa start to affect relations wi th the rest of southern Africa, it wi 11 be necessary to understand the interaction between the states from an interdependency perspective if cooperation within the region wi 11 be successful. By appl ying an interdependence framework, this study aims at contributing to the understanding of relations among the countries of southern Africa in general, and between South Africa and Zimbabwe in particular.

Course/instructor evaluation : perspectives of part-time graduate students

This study explored 6 part-time graduate students' perspectives on course/instructor evaluation. The purpose was to explore whether a link exists between the evaluation for course and instructors as contained in the Faculty of Education courselinstructor evaluation form and the needs of part-time students enrolled in that program. The literature review provided contextual information concerning the 3 main subject areas based upon which the research questions were designed: learner needs in the context of part-time graduate students, courselinstructor eval~ation, and the potential lack of congruency between the 2. Using a semistructured interview process, participants identified criteria important or relevant to the evaluation process and incongruent with the course/instructor evaluation form. A qualitative research methodology using a grounded theory approach contributed to the theory on the nature of course evaluation instruments in a graduate program and addressed the notion of where power was situated within the evaluation process. Findings suggested that the concepts of relevance and the instructor's role that participants identified as important in their graduate learning experience were congruent with what they considered important components of the course/instructor evaluation form. Participants noted a lack of congruency between their expectations of a quality graduate learning experience and the format, content, intent, and timing of the evaluation process. The study confirmed that students did want a voice in the evaluation of their learning experience at both the course and program levels.
