Changing roles of nurse educators employed in acute and chronic care settings : the impact of professional and statutory mandates in Ontario at four sites of one hospital corporation /

The role of the hospital-employed nurse educator is evolving. Factors influencing this change include the introduction of standards for nurse educators by the College of Nurses of Ontario (CNO), a change in the way nurses are educated, the emergence of nursing as a profession, and hospital restructuring as a result of budgetary constraints. Two of these influencing factors: the introduction of the updated Standards of Practice for Registered Nurses and Registered Practical Nurses (1996) and hospital restructuring occurred over the last 7 years at several hospitals in southern Ontario. Current literature as well as the Standards of Practice (1996) were utilized to examine the current roles and responsibilities of nurse educators and subsequently develop a questionnaire to study the impact of these influencing factors on the role of the nurse educator. This questionnaire was piloted and revised before its distribution at 4 hospitals in southern Ontario. Twenty-five of the 41 surveys (61%) distributed were returned for analysis. The data reflected that the Standards of Practice had a positive influence on the role of the nurse educator, while hospital restructuring had a negative impact. In addition, many of the roles and responsibilities identified in the literature were indeed part of the current role of nurse educators, as well as several responsibilities not captured in the literature. The predictions for the future of this role in its current state were not positive given the financial status of the health care system as well as the lack of clarity for the role and the current level ofjob satisfaction among practicing nurse educators. However, a list of recommendations were generated which, if implemented, could add clarity to the role and improve job satisfaction. This could enhance the retention of current nurse educators and the possibility of recruiting competent nurse educators to the role in the future.

An investigation into the functional role of the D1:1 and D1:2 polypeptides in photosystem II in cyanobacteria : the effect of changing PSI/PSII ratio on photoinhibition in Synechococcus sp. PCC7942 /

The cyanobacterium Synechococcus sp. PCC 7942 (Anacystis nidulans R2) adjusts its photosynthetic function by changing one of the polypeptides of photosystem II. This polypeptide, called Dl, is found in two forms in Synechococcus sp. PCC 7942. Changing the growth light conditions by increasing the light intensity to higher levels results in replacement of the original form of D 1 polypeptide, D 1: 1, with another form, D 1 :2. We investigated the role of these two polypeptides in two mutant strains, R2S2C3 (only Dl:l present) and R2Kl (only Dl:2 present) In cells with either high or low PSI/PSII. R2S2C3 cells had a lower amplitude for 77 K fluorescence emission at 695 nm than R2Kl cells. Picosecond fluorescence decay kinetics showed that R2S2C3 cells had shorter lifetimes than R2Kl cells. The lower yields and shorter lifetimes observed in the D 1 and Dl:2 containing cells. containing cells suggest that the presence of D 1: 1 results in more photochemical or non-photochemical quenching of excitation energy In PSII. One of the most likely mechanisms for the increased quenching in R2S2C3 cells could be an increased efficiency in the transfer of excitation energy from PSII to PSI. However, photophysical studies including 77 K fluorescence measurements and picosecond time resolved decay kinetics comparing low and high PSI/PSII cells did not support the hypothesis that D 1: 1 facilitates the dissipation of excess energy by energy transfer from PSII to PSI. In addition physiological studies of oxygen evolution measurements after photoinhibition treatments showed that the two mutant cells had no difference in their susceptibility to photoinhibition with either high PSI/PSII ratio or low PSI/PSII ratio. Again suggesting that, the energy transfer efficiency from PSII to PSI is likely not a factor in the differences between Dl:l and Dl:2 containing cells.

Rights jurisprudence and the charter : evaluating the changing structure of Canadian federalism /

Abstract . Rights jiirisprudence in Canada dates back as far as Confederation in 1867. Between this date and 1982, the organizing principle of Confederation - federalism - has kept this jurisprudence solely within the supremacy of Parliament, subject to its confines and division of powers. After 1982, however, a new constitutional organizing principle was introduced, when Prime Minister Pierre Trudeau introduced the patriation initiative, touted as the "people's package". Individual rights and freedoms were now guaranteed by the Constitution. Citizens of Canada now had a direct link to the Constitution via the Charter and there were now two significantly different organizing principles within the constitutional order widch created an unstable coexistence. This instability has led to a clash between judicially enforced Charter rights and federalism. The Charter has since had both a nationalizing and centralizing effect on Canadian federalism. This thesis explores the relationship between rights and federalism in Canada fix)m Confederation to present day by comparing the jurisprudence of pre and post Charter Canada. An analysis of Supreme Court's (and its predecessor's, the JCPC) decisions shows the profound effect the Charter has had on Canadian federalism. The result has been an undermining of federalism in Canada, with Parliamentary Supremacy replaced by Constitutional supremacy, and ultimately. Judicial Supremacy. Moreover, rights discourse has largely replaced federalism discourse. Canadians have become very attached to their Charter, and are unwilling to allow any changes to the constitution that may affect their rights as political elites discovered the hard way after the collapse of the Meech and Charlottetown Accords. If federalism is to remain a relevant and viable organizing principle in the Constitution, then governments, especially at the provincial level, must find new and iimovative ways to assert their importance within the federation.

The capillary supply of human skeletal muscle in health and disease

BACKGROUND: Capillaries function to provide a surface area for nutrient and waste exchange with cells. The capillary supply of skeletal muscle is highly organized, and therefore, represents an excellent choice to study factors regulating diffusion. Muscle is comprised of three specific fibre types, each with specific contractile and metabolic characteristics, which influence the capillary supply of a given muscle; in addition, both environmental and genetic factors influence the capillary supply, including aging, physical training, and various disease processes. OBJECTIVE: The present study was undertaken to develop and assess the functionality of a data base, from which virtual experiments can be conducted on the capillary supply of human muscle, and the adaptations of the capillary bed in muscle to various perturbations. METHODS: To create the database, an extensive search of the literature was conducted using various search engines, and the three key words - "capillary, muscle, and human". This search yielded 169 papers from which the data for the 46 variables on the capillary supply and fibre characteristics of muscle were extracted for inclusion in the database. A series of statistical analyses (ANOVA) were done on the capillary database to examine differences in skeletal muscle capillarization and fibre characteristics between young and old individuals, between healthy and diseased individuals, and between untrained, endurance trained, endurance welltrained, and resistance trained individuals, using SAS. RESULTS: There was a significantly higher capillarization in the young compared to the old individuals, in the healthy compared to the diseased individuals, and in the endurance-trained and endurance well-trained compared to the untrained individuals. CONCLUSIONS: The results of this study support the conclusion that the capillary supply of skeletal muscle is closely regulated by factors aimed at optimizing oxygen and nutrient supply and/or waste removal in response to changes in muscle mass and/or metabolic activity.

Manpower development and nation-building : Singapore's experience

Manpower is a basic resource. It is the indispensable means of converting other resources to mankind '.s use and benefit. As a process· of increasing the knowledge, skills, and dexterity of the people of a society, manpower development is the most fundamental means of enabling a nation to acquire the capacities to bring about its desired future state of affairs -- a more mighty and wealthier nation. Singapore's brief nation-building history justifies the emphasis accorded to the importance of good quality human resources and manpower development in economic and socio-political developments. As a tiny island-state with a poor natural resource base, Singapore's long-term survival and development depend ultimately upon the quality and the creative energy of her people. In line with the nation-building goals and strategies of the Republic, as conditioned by her objective setting, Singapore's basic manpower development premise has been one of "quality and not quantity". While implementing the "stop-at-two" family planning and population control programs and the relevant immigration measures to guard against the prospect of a "population explosion", the Government has energetically fostered various educational programs, including vocational training schemes, adult education programs, the youth movement, and the national service scheme to improve the quality of Singaporeans. There is no denying that some of the manpower development measures taken by the Government have imposed sacrifice and hardship on the Singapore citizens. Nevertheless, they are the basic conditions for the island-Republic's long-term survival and development. It is essential iii to note that Singapore's continuing existence and phenomenal-success are largely attributable to the will, capacities and efforts of her leaders and people. In the final analysis, the wealth and the strength of a nation are based upon its ability to conserve, develop and utilize effectively the innate capacities of its people. This is true not only of Singapore but necessarily of other developing nations. It can be safely presumed that since most developing states' concerns about the quality of their human resources and the progress of their nation-building work are inextricably bound to those about the quantity of their population, the "quality and not quantity" motto of Singapore's manpower development programs can also be their guiding principle.

Postglacial water levels in the Great Lakes Region in relation to Holocene climate change : Thecamoebian and Palynological evidence /

Various lake phases have developed in the upper Great Lakes in response to isostatic adjustment and changes in water supply since the retreat of the Laurentide Ice Sheet. Georgian Bay experienced a lowstand that caused a basin wide unconformity approximately 7,500 years ago that cannot be explained by geological events. Thecamoebians are shelled protozoans abundant in freshwater environments and they are generally more sensitive to changing environmental conditions than the surrounding vegetation. Thecamoebians can be used to reconstruct the paleolimnology. The abundance of thecamoebians belonging to the genus Centropyxis, which are known to tolerate slightly brackish conditions (i.e. high concentrations of ions) records highly evaporative conditions in a closed basin. During the warmer interval (9000 to 700 yBP), the Centropyxis - dominated population diminishes and is replaced by an abundant and diverse Difflugia dominate population. Historical climate records from Tobermory and Midland, Ontario were correlated with the Lake Huron water level curve. The fossil pollen record and comparison with modem analogues allowed a paleo-water budget to be calculated for Georgian Bay. Transfer function analysis of fossil pollen data from Georgian Bay records cold, dry winters similar to modem day Minneapolis, Minnesota. Drier climates around this time are also recorded in bog environments in Southem Ontario - the drying of Lake Tonawanda and inception of paludification in Willoughby Bog, for instance, dates around 7,000 years ago. The dramatic impact of climate change on the water level in Georgian Bay underlines the importance of paleoclimatic research for predicting future environmental change in the Great Lakes.

Show me, help me, let me : supporting teachers' changing conceptions of reading assessment and reading instruction

This qualitative inquiry used case study methodology to explore the change processes of 3 primary-grade teachers throughout their participation in 7 -month professional learning initiative focused on reading assessment and instruction. Participants took part in semimonthly inquiry-based professional learning community sessions, as well as concurrent individualized classroom-based literacy coaching. Each participant's experiences were first analyzed as a single case study, followed by cross-case analyses. While their patterns of professional growth differed, findings documented how all participants altered their understandings of the roles and relevancy of individual components of reading instruction (e.g., comprehension, decoding) and instructional approaches to scaffold students' growth (e.g., levelled text, strategy instruction), and experienced some form of conceptual change. Factors identified as affecting their change processes included; motivation, professional knowledge, professional beliefs (self-efficacy and theoretical orientation), resources (e.g., time, support), differentiated professional learning with associated goal-setting, and uncontrollable influences, with the affect of each factor compounded by interaction with the others. Comparison of participants' experiences to the Cognitive-Affective Model of Conceptual Change (CAMCC) and the Interconnected Model of Teacher Professional Growth (IMTPG) demonstrated the applicability of using both conceptual models, with the IMTPG providing macrolevel insights over time and the CAMCC microlevel insights at each change intervaL Recommendations include the provision of differentiated teacher professional learning opportunities, as well as research documenting the effects of teacher mentorship programs and the professional growth of teacher educators. ii

Walker Brothers Quarries Limited fonds, 1975, 1980-1981, 1984, 1987-1989

Serving the Niagara and surrounding areas for over 120 years, Walker Industries has made its impact not only commercially, but also culturally. Beginning in 1875 with the erection of a stone sawing mill on a property John Walker purchased from the Welland Canal Loan Company. One of the first projects Walker cut stone for was the Merritton Town Hall. In 1882 the business expanded to include Walkers children, changing the name to Walker & Sons. Eventually in 1887 the two eldest sons took control of the business operation and their partnership changed the company’s name to Walker Brothers, the same year the company began operating its first quarry. The quarry was conveniently located alongside the 3rd Welland canal, offering easy access to Toronto and Hamilton. It was also close to the railway system which allowed immediate access to Thorold and Niagara Falls and later access to parts of Ontario and Quebec. The quarry supplied stone to build numerous halls and armouries across Ontario. A use was also found for the ‘waste products’ of cutting the limestone. Leftover stone chips were sent to paper mills, where stone was needed as part of the sulphite pulp process for making paper. Beginning to supply the Ontario Paper Company with stone in 1913, meant not only long, hard, work, but also more profit for the company. Before mechanization, most of the loading and unloading of the stone was done by hand, taking 19 man-hours to load an 18 yard railway car. Mechanization followed in 1947 when the plant became fully mechanized making the work easier and increasing production rates. In 1957 the company moved from its original location and opened the St. Catharines Crushed Stone Plant.

The new blockbuster film sequel : changing cultural and economic conditions within the film industry

Film sequels are a pervasive part of film consumption practices and have become an important part of the decision making process for Hollywood studios and producers. This thesis indicates that sequels are not homogenous groups of films, as they are often considered, but offer a variety of story construction and utilize a variety of production methods. Three types of blockbuster sequel sets are identified and discussed in this thesis. The Traditional Blockbuster Sequel Set, as exemplified by Back to the Future (1985, 1989, 1990) films, is the most conventional type of sequel set and capitalizes on the winning formula of the first film in the franchise. The MultiMedia Sequel Set, such as The Matrix (1999,2003) trilogy, allows the user/viewer to experience and consume the story as well as the world of the film through many different media. The Lord a/ the Rings (2001, 2002, 2003) set of films is an illustration of The Saga Sequel Set where plot lines are continuous over the entire franchise thus allowing the viewer to see the entire set as a unified work. The thesis also demonstrates how the blockbuster sequel sets, such as the Pirates a/ the Caribbean (2003, 2006, 2007) franchise, restructure the production process of the Hollywood film industry.

Untangling the Organizational Ambiguities in Supply Chain Risk Recognition, Assessment, and Response: The Role of Network Embeddedness

In this thesis, I focus on supply chain risk related ambiguity, which represents the ambiguities firms exhibit in recognizing, assessing, and responding to supply chain disruptions. I, primarily, argue that ambiguities associated with recognizing and responding to supply chain risk are information gathering and processing problems. Guided by the theoretical perspective of bounded rationality, I propose a typology of supply chain risk related ambiguity with four distinct dimensions. I, also, argue that the major contributor to risk related ambiguity is often the environment, specifically the web of suppliers. Hence, I focus on the characteristics of these supplier networks to examine the sources of ambiguity. I define three distinct elements of network embeddedness – relational, structural, and positional embeddedness – and argue that the ambiguity faced by a firm in appropriately identifying the nature or impacts of major disruptions is a function of these network properties. Based on a survey of large North American manufacturing firms, I found that the extent of the relational ties a firm has and its position in the network are significantly related to supply chain risk related ambiguity. However, this study did not provide any significant support for the hypothesized relationship between structural embeddedness and ambiguity. My research contributes towards the study of supply chain disruptions by using the idea of bounded rationality to understand supply chain risk related ambiguity and by providing evidence that the structure of supply chain networks influences the organizational understanding of and responses to supply chain disruptions.

New Teacher Perceptions of Inclusive Pedagogies: Designing New Future for the Changing Classroom

Our perceptions of knowledge attainment have changed (Bezemer & Kress, 2010). The type of students our teachers once were is vastly different from the students they currently teach. We need our next generation to thrive in a dynamically, interactive world saturated with opportunities for meaning making (Kress & Selander, 2012). Our current students are responsible for continuing our society, but that does not mean we need them to become us (Gee, 2009). Rather desperately, we need them to be thinkers and expressive in a variety of modes. The world will be different when they take their rightful place as the next generation of leaders, and so too must their thinking be different (Cope & Kalantzis, 2000). This explanatory mixed-method study (Creswell, 2013; Mertens, 2014) involved an investigation into perceptions of new teachers regarding inclusive pedagogies like Universal Design for Learning (CAST, 2011). It specifically discusses the contemporary thinking of 44 new Ontario teachers regarding inclusive pedagogies in their teacher education as well as their relative intent to utilize them in their practice. This study reveals a distinct tone of skepticism and provides suggestions for the continued improvement of teacher education programs in this province.
