This project was undertaken to study diatom communities from rivers in close proximity to tar sands development in the Athabasca River watershed, Alberta, Canada. Over the past years, tar sands development in Alberta has been intensified and presents new challenges for environmental management in Alberta. As the predominant technologies for extracting bitumen from the tar sands rely on large amounts of freshwater, concerns on the water quality of natural water bodies and its impacts on aquatic life and human health are increasing. Although limited information on the diatom communities in this region is available from the late 1970s and early 1980s, there are no reference diatom communities with which to compare modern-day samples. In this study, water and diatom samples were collected from nine sites in 2008 and replicate samples were collected from a subset of those sites in 2009. Based on the few samples available, it was not possible to directly link tar sands-related pollution with changes in diatom community structure, although diatoms clearly showed a response to dissolved organic carbon (DOC) and conductivity. However, diatom communities collected represent a benchmark for biomonitoring assessment in the region following expansion of the industry and represent valuable information for future studies.

Purpose: Leadership is an interactive concept that influences our daily lives. A quality concept is an approach and philosophy that leaders use to incorporate the leadership process into the organization successfully. Both concepts have an incremental history, correlation, and discussion. However, the two concepts have not yet been theoretically and empirically integrated. This paper attempts to integrate and discuss leadership and quality to create a single quality leadership style based on the definition of quality gurus and the leadership styles which relate more towards the quality of leadership. Methodology: The study used a systematic literature review to review the past literature related to the field of leadership and quality management. This study provides the constructs from definitions proposed by experts in this field. Each leadership styles have many constructs that may or may not be related to quality. Results: The study proposed a conceptual framework which combined the definitions of quality gurus and the different leadership styles. The finding of this study has contributed to the expansion of theoretical knowledge in the field of quality leadership style. Implications: This paper indicated that the review of the literature regarding what quality gurus define as important relating to leadership. This paper provides the constructs from quality gurus definitions. Novelty: Each leadership styles have many constructs that may or may not be related to quality. Therefore, future studies need to consider what the constructs from those leadership styles are considered effective to quality.

Colony housing of cats allows shelters to maximize the number of cats housed in limited space. Most research on colony-housed cats examines stress in relation to group size or enclosure size.  While this is important for evaluating welfare, it is equally important to understand how cats are interacting socially in these colonies. We observed 259 adult cats housed in groups of two to eight individuals. Scan samples were used to assess how frequently individual cats were in close proximity to other cats. These data were used to measure individual differences in sociability and patterns of proximity to certain partners. We used information about the past history of the cat, which was collected upon admission to the shelter to identify predictors of time spent in proximity. There was a high degree of inter-individual variability in sociability. Strays tended to spend less time in proximity to other cats, and this effect was most pronounced in females.However, none of the information collected upon admission predicted patterns of proximity to certain partners, or which cats spent time in association witheach other. Future studies should explore the implications of differences in sociability by associating observations of social behavior and stress behaviors.

Associations of teachers of Japanese play an indispensable role in assisting not only teachers but also learners and impacting society by offering resources and opportunities for the growth of in-service teachers and pre-service teachers such as postgraduate students. Enhancing the quality of the resources and opportunities is expected to become effective when they know each other, learn from each other and work together. For this purpose, the Association of Japanese Language Teachers in Europe hosted a summit where the representatives of 22 European countries gathered to discuss the current and the future of Japanese language education in Europe. The aim of the current report is to present general but up-to-date information about the teachers, learners, institutions, associations, and features and challenges of each country. Furthermore, this report will illustrate the key discussions of the summit on the challenges and the possible actions for the viable future of Japanese language education in Europe. The Authors hope to contribute to creating the reference points for larger future studies on such associations while reflecting on the impact the summit possibly had.

AbstractHealth-related quality of life (HRQOL) is an important measure of patient experience before, during, and after treatment for skin cancers. Over the past 20 years, a variety of generic as well as disease-specific HRQOL instruments have been developed to assess clinical outcomes. Clinical trials have increasingly focused on using HRQOL instruments as outcome measures. Patients with both cutaneous melanoma and nonmelanotic skin cancers have been found to experience improvement in HRQOL following surgical treatment and reconstruction. Individual demographic variables may further predict experience within each of these groups. Increasing use of HRQOL instruments in future studies comparing skin cancer treatments will allow physicians to better understand and optimize patient experiences.

Africa is favored with characteristic and natural water resources, but misuse of these asserts has been driven to extraordinary contamination of the environment. Populace development and urbanization due to improvements have moreover contributed gigantically to the present water contamination in Africa. The principal causes of contamination for surface waterways are untreated effluents released into the environment by humans and machines. Several African countries have set targets for emissions released into surface waters, but it’s unclear whether they’re being followed. Despite the fact that groundwater sources such as wells and boreholes are important sources of drinking water for Africans, the natural water quality of these groundwater sources is, for the most part, moo within the vicinity due to close proximity to sterile areas. Distinguished sources of water contaminations in Africa incorporate agrarian activities, mining, roadside outflows, wastes from industries and workshops, dumps and e-wastes. Oil leaks are a major problem in oil-rich African countries like Nigeria and Angola. Agrarian practices had the least impact on soil in Africa, whereas e-waste reuse has the highest quantities of Pb, Cu, and Zn (>1%). In Africa, there is a need for effective natural toxin control. This paper analyzes and summarizes the recent scholarship on water pollution on the African continent. It gives the past and current overview of the research breakthrough among the African scholars and scholars from the diaspora working on water pollution.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Presently, no clear picture is available about the facilities providing clinical services for persons who stutter (PWS) in Kuwait. This information is crucial for any awareness program to be established in the future. The purpose of this study was to identify clinical facilities and speech-language personnel that provide services for PWS in Kuwait. Participants consisted of 21 clinical directors of governmental medical centers, non-profit clinics, and private clinics as well as department heads of governmental school clinics where speech-language services were provided. Participants were interviewed regarding the availability of speech-language services within their centers and whether or not PWS receive services. The results revealed that four out of five governmental medical centers with a total of 32 speech-language pathologists (SLPs) provided services for PWS. Additionally, 12 schools of special education were found to have 62 SLPs on their staff providing fluency services for students. Finally, two stand-alone private clinics and one non-profit clinic provided services for PWS. Results indicated an overall shortage of SLPs in the country, especially in medical settings. This study sets the foundation for a series of future studies investigating the type and quality of stuttering services provided by the identified facilities in Kuwait.

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

Heart failure (HF) affects more than 5 million people and has an increasing incidence and cost burden. Patients note symptoms of dyspnea and fatigue that result in a decreased quality of life, which has not drastically improved over the past decades despite advances in therapies. The assessment of exercise capacity can provide information regarding patient diagnosis and prognosis, while doubling as a potential future therapy. clinically, there is acceptance that exercise is safe in hf and can have a positive impact on morbidity and quality of life, although evidence for improvement in mortality is still lacking. specific prescriptions for exercise training have not been developed because many variables and confounding factors have prevented research trials from demonstrating an ideal regimen. Physicians are becoming more aware of the indices and goals for hf patients in exercise testing and therapy to provide comprehensive cardiac care. it is further postulated that a combination of exercise training and pharmacologic therapy may eventually provide the most benefits to those suffering from hf.
