This study investigated external and internal accountability of foreign ESL teachers in China through a comparison with Chinese local ESL teachers. A cross-sectional survey design was used. Two research questions were developed from a literature review to examine foreign ESL teachers' perceptions toward external accountability and internal accountability. Questionnaires from forty-five ESL teachers and eighty-one Chinese local ESL teachers were collected through an on-line survey. Data of teachers' perceptions towards four constructs: external accountability (outside expectations), external accountability (school management), internal accountability (professional duty), and internal accountability (feelings about work), were analyzed. The findings showed that foreign teachers perceived that they were held externally accountable with regard to outside expectations, and they were not held externally accountable for school management. In terms of internal accountability, foreign teachers perceived that they held themselves highly accountable in both the construct of professional duty and the construct of feelings about work.

This Paper discusses the food and beverage machines that are located at Memorial University's Grenfell Campus and endeavors to assess how much those vending machines are being used and how they affect sustainability initiatives on campus. A survey was conducted to gauge the use of vending machines, their content and what is purchased, and if participants did not purchase from thes machines they were also asked why they did not.This survey produced many other questions that are directly linked to vending machines.Water quality on campus was heavily disscussed, along with the use of bottled water and implications associated with drinking only from bottles that are thrown away. The study concludes with a discussion of the alternative choices that can be implemented to replace vending machines.

Universities have a special capacity and responsibility to address climate change and this paper focuses on carbon inventories as an important tool for reducing emissions on university campuses. I first describe carbon inventories then analyze three universities that have already developed sustainability action and baseline inventories: Dalhousie University, Mount Allison University, and the University of Victoria. From the case studies, I identify and discuss six conditions important for the successful implementation of carbon inventories. Finally, the case study findings are applied to Grenfell Campus and a carbon inventory implementation plan is proposed for this institution. The paper draws on qualitative Methodologies (interviews and case studies) using the theoretical frame work of ecological economics and the concepts of externalities, sustainable development, and policy instruments.

The purpose of this study was to examine if the effects of exposure to educational videos on climate change and exposure to a view of nature could elicit environmentalist behaviours and increase one’s environmental identity. It was predicted that participants who were exposed to a view of nature and saw a video on climate change would have a higher likelihood to plant a seed and experience greater connectedness to nature. Fifty-four students (38 females, 15 males, and 1 gender fluid) with ages ranging from 18 to 47 were recruited for the experiment. A 2 (type of video) x 2 (type of view) factorial design was conducted, in which participants were randomly assigned to watch either an educational video on climate change or on popsicles, and they either had a view of outdoors or indoors. There was no significant interaction for setting and video (p = .172) on whether participants chose to plant a seed or not. Likewise, there was no significant interaction for setting and video (p = .262) on planting intentions. There was a significant effect for the video on experiencing connection to nature (p = .039, ηp2 = .08). These findings suggest that this video could change one’s perception of nature.

Thiosalt species are unstable, partially oxidized sulfur oxyanions formed in sulfur-rich environments but also during the flotation and milling of sulfidic minerals especially those containing pyrite (FeS₂) and pyrrhotite (Fe₍₁₋ₓ₎S, x = 0 to 0.2). Detecting and quantifying the major thiosalt species such as sulfate (SO₄²⁻), thiosulfate (S₂O₃²⁻), trithionate (S₃O₆²⁻), tetrathionate (S₄O₆²⁻) and higher polythionates (SₓO₆²⁻, where 3 ≤ x ≤ 10) in the milling process and in the treated tailings is important to understand how thiosalts are generated and provides insight into potential treatment. As these species are unstable, a fast and reliable analytical technique is required for their analysis. Three capillary zone electrophoresis (CZE) methods using indirect UV-vis detection were developed for the simultaneous separation and determination of five thiosalt anions: SO₄²⁻, S₂O₃²⁻, S₃O₆²⁻, S₄O₆²⁻ and S₅O₆²⁻. Both univariate and multivariate experimental design approaches were used to optimize the most critical factors (background electrolyte (BGE) and instrumental conditions) to achieve fast separation and quantitative analysis of the thiosalt species. The mathematically predicted responses for the multivariate experiments were in good agreement with the experimental results. Limits of detection (LODs) (S/N = 3) for the methods were between 0.09 and 0.34 μg/mL without a sample stacking technique and nearly four-fold increase in LODs with the application of field-amplified sample stacking. As direct analysis of thiosalts by mass spectrometry (MS) is limited by their low m/z values and detection in negative mode electrospray ionization (ESI), which is typically less sensitive than positive ESI, imidazolium-based (IP-L-Imid and IP-T-Imid) and phosphonium-based (IP-T-Phos) tricationic ion-pairing reagents were used to form stable high mass ions non-covalent +1 ion-pairs with these species for ESI-MS analysis and the association constants (Kassoc) determined for these ion-pairs. Kassoc values were between 6.85 × 10² M⁻¹ and 3.56 × 10⁵ M⁻¹ with the linear IP-L-Imid; 1.89 ×10³ M⁻¹ and 1.05 × 10⁵ M⁻¹ with the trigonal IP-T-Imid ion-pairs; and 7.51×10² M⁻¹ and 4.91× 10⁴ M⁻¹ with the trigonal IP-T-Phos ion-pairs. The highest formation constants were obtained for S₃O₆²⁻ and the imidazolium-based linear ion-pairing reagent (IP-L-Imid), whereas the lowest were for IP-L-Imid: SO₄²⁻ ion-pair.

Combinatorial designs are used for designing key predistribution schemes that are applied to wireless sensor networks in communications. This helps in building a secure channel. Private-key cryptography helps to determine a common key between a pair of nodes in sensor networks. Wireless sensor networks using key predistribution schemes have many useful applications in military and civil operations. When designs are efficiently implemented on sensor networks, blocks with unique keys will be the result. One such implementation is a transversal design which follows the principle of simple key establishment. Analysis of designs and modeling the key schemes are the subjects of this project.

This mixed method case study explored the capacity challenges of neighbourhood based community centres related to the areas of governance and leadership, program delivery, financial management and human resources. The study involved the examination of three community centres with multi-mandates (i.e., provide programs and services to individuals from pre-school to seniors in the areas of social, educational, recreational and health) and utilized three phases of data collection: 1) surveys with board members; 2) focus groups with all boards and staff; and 3) document review which examined pertinent organizational policies and procedures. Questions were aimed at gaining an understanding of some of the challenges faced by staff and administrators of neighbourhood based community centres, as there a gap in the research in this particular area. Research findings identified a number of related challenges facing non-profit organizations specifically in the areas of funding and staffing and how these challenges impact both day to day operations and longer term sustainability. More research is needed with nonprofit organizations that have these broader mandates and diverse operational challenges, hence greater capacity building challenges.

In this study, a mixed method approach was used to examine the experience of 43 domestic peer mentors who participated in a peer mentoring program for international students offered at Memorial University of Newfoundland, St. John’s, Canada. The study aimed to answer the following questions: 1) does participating in a mentorship program for international students result in change in the intercultural development for domestic peer mentors as measured by the Intercultural Development Inventory (IDI)? 2) what were the experiences of domestic peer mentors participating in a peer mentoring program for international students? Following the Developmental Model of Intercultural Sensitivity (Bennett, 1998) as a guide, this study used the scores from the Intercultural Development Inventory (IDI) to gain an understanding of the influence of the program. The scores obtained pre and post mentorship experiences were compared and a significant difference was found. Reflections from 120 monthly reports and seven individual semi-structured interviews were also conducted to gain a deeper understanding of the mentorship experience and the influence it had on the mentors’ intercultural development. The benefits of intercultural peer mentoring on student development of skills such as leadership, communication and empathy are also discussed. The study echoes previous research that calls for an increased amount of facilitated intercultural program within university campuses. The study also advocates for further implementation of programs that provide opportunities for intercultural learning between domestic and international students in order for intercultural development to improve in higher educational settings.

In this thesis, we consider N quantum particles coupled to collective thermal quantum environments. The coupling is energy conserving and scaled in the mean field way. There is no direct interaction between the particles, they only interact via the common reservoir. It is well known that an initially disentangled state of the N particles will remain disentangled at times in the limit N -> [infinity]. In this thesis, we evaluate the η-body reduced density matrix (tracing over the reservoirs and the N - η remaining particles). We identify the main disentangled part of the reduced density matrix and obtain the first order correction term in 1/N. We show that this correction term is entangled. We also estimate the speed of convergence of the reduced density matrix as N -> [infinity]. Our model is exactly solvable and it is not based on numerical approximation.

Background: Obstructive airway diseases (OADs) are among the leading causes of morbidity and mortality worldwide. Shortness of breath (SOB) is the main symptom associated with OADs. International guidelines from the Global Initiative for Chronic Lung Disease (GOLD) and the Global Initiative for Asthma (GINA) have recommended spirometry as an indispensable tool for the diagnosis of asthma and chronic obstructive pulmonary diseases (COPD), but spirometry is rarely used in family practice. Simple and reliable diagnostic tools are necessary for screening community patients with onset of OADs for timely management. Purpose: This thesis examined screening utility of the PiKo-6 forced expiratory volume in one second (pFEV₁) , in six second (pFEV₆), and the pRatio ( pFEV₁/pFEV₆) in SOB patients for OADs in community pharmacy settings. FEV₆ has recently been suggested an excellent surrogate for Forced Vital Capacity (FVC), which requires maximum exhalation of the lungs. Methods: Patients with SOB symptoms who were prescribed pulmonary inhalers, by their family physicians, were recruited via community pharmacies. Trained pharmacists collected two PiKo-6 tests to assess the repeatability of the PiKo-6 device. All patients performed laboratory spirometry ( FEV₁, FVC and FEV₁/FVC) to obtain physician diagnosis of their OADs. The results of the PiKo-6 spirometer and laboratory spirometer were compared. In addition, the PiKo-6 pRatio and laboratory FEV₁/FVC were assessed against physician diagnosed COPD. Results: Sixty three patients volunteered to perform the PiKo-6 spirometry. Of these, 52.4 % were men (age 53.9 ± 15.3 years; BMI 31.9 ± 7.40 kg/m2). Repeated testing with pFEV₁, pFEV6 and pRatio correlated significantly (within correlation, r = 0.835, p-Value≤ 0.05 ; 0.872, p- Value≤ 0.05; and 0.664, p-Value≤ 0.05). In addition, pFEV₁, pFEV6 and pRatio correlated significantly with FEV₁, FVC and FEV₁/FVC, respectively (between correlation = 0.630, p- Value≤ 0.05 ; 0.660, p-Value≤ 0.05 and 0.580, p-Value≤ 0.05). The cut-off value corresponding to the greatest sum of sensitivity and specificity of pRatio for physician-diagnosed COPD was <0.80, the sensitivity and specificity were 84 % and 50%, respectively. Conclusions The portable PiKo-6 correlates moderately well with the standard spirometry, when delivered by community pharmacists to patients with OADs. The PiKo-6 spirometer may play a role in screening patients suspected of having an OAD in community pharmacies that may benefit from early physician diagnosis and appropriate management.

This thesis presents the discovery of eight submerged deltas (-19 to -45m), the first documented submerged boulder barricade, a submerged sill platform and spits off the coast of Cumberland Peninsula, eastern Baffin Island, NU. The geomorphic characteristics of these features in relation to contemporaneous sea-level are presented and compared with the modern shore-zone. The submerged boulder barricade at Qikiqtarjuaq in the west indicates a -16 m sea level that isolated Broughton Channel from Baffin Bay to the north, changing the coastal dynamics from those observed at present. A shoreline deeper than -50 m planed off the fiord-mouth sill in Akpait Fiord and formed spits at -50 m and -30 m present depth. These features define a submerged shoreline gradient of 0.35 m/km to the east across northeastern Cumberland Peninsula. The linear gradient sediment supply requirements for delta formation suggest a synchronous lowstand, bracketed by ice margins and sourced from glacial outwash between 11.8-8.5 ka. This confirms the submergence trend hypothesized for eastern Cumberland Peninsula (Dyke, 1979).

A Totally Enclosed Motor Propelled Survival Craft (TEMPSC) is currently the primary mode of escape during a maritime and offshore emergency situation. Although lifeboats have evolved from their original design, the interior comfort and habitability of the craft has remained virtually unchanged and is not considered during the certification process. Ambient carbon dioxide (CO₂) accumulation within TEMPSC is one factor, along with many others that may cause serious health implications for TEMPSC occupants. Previous research has shown that with the hatches closed and the participants at rest, an international 8-hour exposure limit of 4800ppm may be reached in as little as 15 minutes. This study uses simulation as a testing methodology to determine if vessel motions in various sea-states impact the time to reach this same CO₂ exposure limit because of physical exertions of the participants to maintain stability within their seats.
