Despite the increasing public profile of lesbian childbearing, public health resources for expectant women often bear heterosexist assumptions and create barriers to accessing information relevant to lesbian mothering experiences. This descriptive, exploratory study examined one lesbian couple's perceived educational needs for effective support, barriers to access, strategies for locating care, and the impact of childbearing on their lives, as well as their reflections on inviting ways to offer supportive practices in a public health context. A case study approach used feminist ethnographic methodology and purposeful convenience sampling. A prenatal and a postnatal open-ended interview were completed with 1 white, middle-class, able, lesbian childbearing couple, each ofwhom has birthed as coparent and biological mother in this couple relationship. Despite this couple's immense situated privilege, they struggled to locate the support they sought for childbearing in a way that offered optimal emotional and physical care from the preconceptual to postpartum stages and which maintained confidentiality or anonymity as desired. They created meaningful care through personal networks. The findings were framed using invitational and feminist theories: how people, places, programs, processes, policies, and politics contributed to educational support. A three part conceptual framework emerged which identified components of access to support: perceived safety of resources, disclosure status, situated privilege, and public or private availability of information. The consequences of lack of public access to comprehensive childbearing care for lesbian women and their communities are described. Educational possibilities addressed systemic heterosexism through the development of sensitive educators, meaningful curriculum, program planning, explicit policies, community partnerships, and political leadership with respect to both institutional and research venues.

The purpose of this study was to examine processes and interactions that characterized positive developmental experiences in sport. A highly competitive and reputable U-17 girls' soccer team was chosen for the study through purposeful sampling, providing an information rich case from which data could be derived (Patton, 2002). Seventeen players and three coaches participated in this study. Based on an ethnographic methodology data were collected via observations and both informal and formal semi-structured interviews. Tlie data were coded according to the three procedures outlined by Seidel and Kelle (1995): a) noticing relevant phenomena, b) collecting examples of those phenomena, and c) analyzing those phenomena in order to find commonalities, differences, patterns and structures. Significant events and underlying themes were recounted chronologically through a collection of vignettes, aimed to provide a contextual lens for the reader. Results revolved around two prominent themes: Teamwork and leadership. These were closely related concepts that required players to demonstrate a wide range of developmental skills for the team to move collectively towards their end goal. Furthermore, teamwork and leadership experiences took both desirable and undesirable forms. For example, at the beginning of the season competition existed amongst the players at the expense of teamwork and leadership. As the season progressed the pursuit of a shared goal allowed the players to view each other as collaborators and teamwork and leadership skills became increasingly evident. At times, however, success on the field was prioritized above maintaining relationships off the field, requiring the coaches to intervene and re-establish equilibrium.

The research question in this study was "How do the noninstitutionalized elderly in the Hamilton-Wentworth Region perceive their learning needs and interests related to health?" The theoretical foundations of instruction for adults were reviewed as well as learning needs and interests in adult education, the assessment of learning needs in general, and the assessment of the learning needs of the elderly. The methodology used was a descriptive design. A research-based questionnaire-interview was developed, refined, and pilot tested. From a random sampling procedure, a participant group of 23 was secured. The questionnaireinterview was administered in a home visit situation. Data, which were collected, were coded, analyzed, processed, and printed. The results indicated that each participant had many learning needs and interests of varying intensities. The participants had many preferences in the delivery of health promotion. The learning needs and interests had several significant correlations with other variables. The implications of the result~ were discussed.

The purpose of this study was to assess the effects of changing a nursing documentation system, developed from King's Conceptual Framework, on the use of the nursing process. The null hypothesis was that there would be no significant increase in the reflection of the use of the nursing process on the nursing care plan or nurses' notes, as a result of using a nursing documentation system developed using King's Conceptual Framework (1981). The design involved the development of a questionnaire that was used to review health records pre and post implementation of a documentation system developed based on King's Conceptual Framework and Theory of Goal Attainment (1981). A Record Completeness Score was obtained from some of the questions. The null hypothesis was rejected. The results of the study have implications for nursing administration and the evaluation of nursing practice. If the use of a documentation system developed from a conceptual framework increases the reflection of the nursing process on the patient's health record, nursing will have the means to measure patient outcomes/goal attainment. All health care organizations and levels of government are focusing on methods to monitor and control the health-care dollar. In order for nursing to clearly determine the costs associated with nursing care, measurement of patient outcomes/goal attainment will need to be possible. In order to measure patient outcomes/goals attainment nurses will need to be able to collect data on their practice. It will be critical that nursing have a documentation system in place which facilitates the reflection of the nursing process within a theoretical framework.

A new approach to treating large Z systems by quantum Monte Carlo has been developed. It naturally leads to notion of the 'valence energy'. Possibilities of the new approach has been explored by optimizing the wave function for CuH and Cu and computing dissociation energy and dipole moment of CuH using variational Monte Carlo. The dissociation energy obtained is about 40% smaller than the experimental value; the method is comparable with SCF and simple pseudopotential calculations. The dipole moment differs from the best theoretical estimate by about 50% what is again comparable with other methods (Complete Active Space SCF and pseudopotential methods).

The prediction of proteins' conformation helps to understand their exhibited functions, allows for modeling and allows for the possible synthesis of the studied protein. Our research is focused on a sub-problem of protein folding known as side-chain packing. Its computational complexity has been proven to be NP-Hard. The motivation behind our study is to offer the scientific community a means to obtain faster conformation approximations for small to large proteins over currently available methods. As the size of proteins increases, current techniques become unusable due to the exponential nature of the problem. We investigated the capabilities of a hybrid genetic algorithm / simulated annealing technique to predict the low-energy conformational states of various sized proteins and to generate statistical distributions of the studied proteins' molecular ensemble for pKa predictions. Our algorithm produced errors to experimental results within .acceptable margins and offered considerable speed up depending on the protein and on the rotameric states' resolution used.

The magnitude of the cervical cancer problem, coupled with the potential for prevention with recent technological advances, made it imperative to step back and reassess strategic options for dealing with cervical cancer screening in Kenya. The purpose of this qualitative study was: 1) to explore the extent to which the Participatory Action Research (PAR) methodology and the Scenario Based Planning (SBP) method, with the application of analytics, could enable strategic, consequential, informed decision making, and 2) to determine how influential Kenyan decision makers could apply SBP with analytic tools and techniques to make strategic, consequential decisions regarding the implementation of a Cervical Self Sampling Program (CSSP) in both urban and rural settings. The theoretical paradigm for this study was action research; it was experiential, practical, and action oriented, and resulted in co-created knowledge that influenced study participants’ decision making. Action Africa Help International (AAHI) and Brock University collaborated with Local Decision Influencing Participants (LDIP’s) to develop innovative strategies on how to implement the CSSP. SBP tools, along with traditional approaches to data collection and analysis, were applied to collect, visualize and analyze predominately qualitative data. Outputs from the study included: a) a generic implementation scenario for a CSSP (along with scenarios unique to urban and rural settings), and b) 10 strategic directions and 22 supporting implementation strategies that address the variables of: 1) technical viability, 2) political support, 3) affordability, 4) logistical feasibility, 5) social acceptability, and 6) transformation/sustainability. In addition, study participants’ capacity to effectively engage in predictive/prescriptive strategic decision making was strengthened.
