Clinical Psychologists\u27 Perceptions of Persons with Mental Illness

Clinical psychologists have an ethical responsibility to monitor the nature and appropriateness of their attitudes toward persons with mental illness. This article presents the results of a survey of randomly selected clinical psychologists who were asked to rate the effectiveness, understandability, safety, worthiness, desirability, and similarity (to the rater) of persons with moderate depression, borderline features, and schizophrenia. The results show that psychologists perceive these individuals differently with respect to these characteristics. The results also suggest that psychologists disidentify or distance themselves from persons with personality and psychotic conditions. Implications for quality improvement and stigma reduction in the field of professional psychology are discussed

Understanding Teachers’ Information Needs, Perceived Competencies, and Information Seeking Behaviours for Special Education Information

The focus of this research is to better understand teachers’ information needs, perceived competencies, preferences for information sources, and information seeking behaviours related to special education by level of teaching experience. A mixed methods approach to research was employed using a combination of quantitative and qualitative methods. Eighty-five elementary and intermediate school teachers (J.K. through Grade 8) from Catholic and public school boards in southern Ontario, Canada, completed an online survey questionnaire. Semi-structured, follow-up interviews were then conducted with 11 teachers to further explore the issues. The participants were classified into three experience level groups (i.e., novice, intermediate, and expert teachers) based on 9 indicators of teaching and special education experience and expertise. The participants’ special education information needs were coded to the Council for Exceptional Children’s (CEC) 10 Professional Standards for Special Education (2009) to better understand how teachers with different levels of experience perceive their special education needs and to examine how their needs relate to the CEC’s Professional Standards. The semi-structured interview data was used to provide further illumination on the results of the survey data. Overall, teachers’ most frequently identified needs involved instructional strategies (including differentiated instruction) and how to create inclusive classrooms. More experienced teachers were better able to identify and articulate their special education needs. Distinct patterns of source preferences were found based on teachers\u27 experience levels. Novice teachers most preferred face-to-face consultations with knowledgeable experts and least preferred sources of information that were passive, individual activities such as searching online; reading professional books, magazines, and research resources; or watching videos. They reported being less successful at finding the specific information they needed from these sources. Expert teachers favoured research and professional literature and online sources. Teachers also indicated a preference for one source of online special education information and reported only using a few websites as their main point of access for special education information: school board websites, the Ontario Ministry of Education website, and a variety of disability association websites. The ultimate goal of this research is to provide information on how to better support and meet teachers’ information needs related to special education

Changes in Soil Microbial Functioning in Coastal Wetlands Exposed to Environmental Stressors and Subsidies

Environmental perturbations are ubiquitous features of ecosystems and shape ecological structure and function. Climate change will alter the intensity and frequency of disturbances and expose ecosystems to novel combinations of useful inputs (subsidies) and harmful inputs (stressors). Coastal wetlands are particularly vulnerable to changing environmental conditions and are increasingly exposed to effects of interacting subsidies and stressors. In particular, the Florida Coastal Everglades, which has experienced accelerated change due to a history of water management practices, is vulnerable to new disturbances associated with climate change. The low-lying Florida Everglades faces multiple disturbances from storm surge, nutrient enrichment, and sea-level rise which will influence its responses to future environmental perturbations. Microbial communities are often used to characterize environmental change because of their high surface area to volume ratio, permeable membrane, and quick turnover rates. Therefore, assessing how microbial function changes can provide insights into how subsidies and stressors interact to alter biogeochemical cycles. I tested how nutrient enrichment can alter ecosystem responses to stress and found that it did not promote recovery in mangrove plants. I examined how long-term exposure to salinity and phosphorus (the limiting nutrient in the Everglades) affected microbial enzyme activity and found that salinity alone acts as a suppressor of enzyme activity but phosphorus addition can mitigate salinity stress in sawgrass soil. I tested how pulses of salinity can affect the microbially-mediated breakdown of organic material and found that the microbial community was functionally redundant and unaffected by saltwater pulses; however, microbial activity was consistently lower in the brackish marsh compared to the freshwater marsh. I investigated how gradients of salinity and phosphorus affected freshwater and brackish soils and determined previous exposure to saltwater intrusion dominates affects microbial function and soil composition. Across these experiments, I found that environmental perturbations alter the microbial-mediated processing of nutrients and carbon, and legacies of previous disturbances influence the microbial response to new disturbance regimes

Idiopathic mediastinal fibrosis

peer reviewedFibrosing mediastinitis is a rare condition characterized by an excessive growth of dense fibrous tissue within the mediastinum. The etiology of the disease is most often a fungal infection and may in some cases be idiopathic. We present the case of a patient with chronic obstructive pulmonary disease (COPD) suffering from fibrosing mediastinitis of undetermined origin and in whom the diagnosis was established by histopathological analysis after mediastinoscopy

Biodegradability of organic matter associated with sewer sediments during first flush

The high pollution load in wastewater at the beginning of a rain event is commonly known to originate from the erosion of sewer sediments due to the increased flow rate under storm weather conditions. It is essential to characterize the biodegradability of organic matter during a storm event in order to quantify the effect it can have further downstream to the receiving water via discharges from Combined Sewer Overflow (CSO). The approach is to characterize the pollutograph during first flush. The pollutograph shows the variation in COD and TSS during a first flush event. These parameters measure the quantity of organic matter present. However these parameters do not indicate detailed information on the biodegradability of the organic matter. Such detailed knowledge can be obtained by dividing the total COD into fractions with different microbial properties. To do so oxygen uptake rate (OUR) measurements on batches of wastewater have shown itself to be a versatile technique. Together with a conceptual understanding of the microbial transformation taking place, OUR measurements lead to the desired fractionation of the COD. OUR results indicated that the highest biodegradability is associated with the initial part of a storm event. The information on physical and biological processes in the sewer can be used to better manage sediment in sewers which can otherwise result in depletion of dissolved oxygen in receiving waters via discharges from CSOS
