Authentic Scientific Inquiry, Student Engagement, and Transformational Learning: Are They Related?

Students on the Beamlines (SotB) is a unique program offering an opportunity for high school students and their teachers to collaborate with scientists to develop, execute, and share an authentic scientific inquiry using techniques offered by the Canadian Light Source (CLS). Canada’s synchrotron is a national science research facility that generates intense beams of x-ray and infra-red light to probe the structure and function of matter. The nature of the SotB program, involving high school students in authentic scientific inquiry, and observation of engaged students provided an opportunity for investigation into these concepts. The purpose of this study was to provide insight into what engaged these students and in particular, to determine if, how and to what extent the authentically scientific nature of the program contributed to student engagement, as well as to determine if, how, and to what extent this unique situation nurtured the potential for a transformational learning experience. To address the research questions qualitative methods were employed to study field notes, correspondence, observations and feedback related to the program and interviews of the student, teacher, and researcher participants. This provided insight into the experiences of the participants that will be of interest to teachers, parents, students, curriculum writers, researchers, funding agencies, outreach program developers, scientific research facilities and others. Through the analysis of literature, this work produced a list of indicators of engagement and attributes of authentic scientific inquiry. These indicators and attributes were used as a framework through which data were analysed resulting in the refinement of these frameworks. In addition, evidence supported a connection between participation in authentic scientific inquiry and the engagement of students, although it also suggested other contributions to engagement. There is also evidence to support the presence of transformational learning for some students and teachers. This thesis presents the evidence in the form of a series of manuscripts drawing conclusions useful for those wishing to create similar science experiences for high school students and for science educators

Object categorisation, object naming, and viewpoint-independence in visual remembering: Evidence from young children's drawings of a novel object

A simple object-drawing task confirms a three-way association between object categorisation, viewpoint independence, and longer-term visual remembering. Young children (5- to 7-year-olds) drew a familiar object or a novel object, immediately after it had been hidden from view or on the following day. Both objects were shown from a full range of viewpoints or from just two viewpoints, from neither of which would either object normally be drawn after unrestricted viewing. When drawing from short-term memory after restricted viewing, both objects were most likely to be depicted from a seen viewpoint. When drawing from longer-term memory after restricted viewing, the novel object continued to be drawn from a seen viewpoint, but the mug was now most likely to be drawn from a preferred viewpoint from which it had not been seen. Naming the novel object with a novel count noun ("Look at this. This is a dax"), to signal that it belonged to an object category, resulted in it being drawn in the same way as the familiar object. The results concur with other evidence indicating that short-term and longer-term visual remembering are differentially associated with viewpoint-dependent representations of individual objects and viewpoint independent representations of object categories, respectively

Comorbidities and Race/Ethnicity Among Adults with Stimulant Use Disorders in Residential Treatment

Comorbid physical and mental health problems are associated with poorer substance abuse treatment outcomes; however, little is known about these conditions among stimulant abusers at treatment entry. This study compared racial and ethnic groups on baseline measures of drug use patterns, comorbid physical and mental health disorders, quality of life, and daily functioning among cocaine and stimulant abusing/dependent patients. Baseline data from a multi-site randomized clinical trial of vigorous exercise as a treatment strategy for a diverse population of stimulant abusers (N = 290) were analyzed. Significant differences between groups were found on drug use characteristics, stimulant use disorders, and comorbid mental and physical health conditions. Findings highlight the importance of integrating health and mental health services into substance abuse treatment and could help identify potential areas for intervention to improve treatment outcomes for racial and ethnic minority groups

Research with bereaved families

Theoretical debates about the nature of grief and bereavement draw attention to the sensitivity of carrying out research with bereaved people, the possible threats that this may pose and the ethical considerations required to ameliorate potentially damaging outcomes. The authors of this article present a framework for ethical decision-making that has been successfully developed in the context of research with bereaved families. The discussion focuses on application and evaluation of the framework during research with family members who were approached about the donation of a deceased relative’s organs and/or tissues for transplantation. Practical strategies of relevance to the processes of participant recruitment, the interview encounter and follow-up care in the post-interview period are identified and discussed. Concerns about the possible impact of bereavement research are balanced with the views of family members who gave credence to the therapeutic and cathartic benefits of participating in sensitive, death-related research. </jats:p

Alcohol dehydrogenase II and fructose-1,6-bisphosphatase appear to be co-regulated in wild-type yeast

AbstractAn activity gel assay for fructose-1,6-bisphosphatase (FBP), the enzyme catalyzing the final step in gluconeogenesis in yeast, has been developed which can be used in conjunction with spectrophotometric assays to show that it is tightly co-regulated with the inducible alcohol dehydrogenase, ADHII. Both enzymes are repressed coordinately in aerobically grown yeast by the addition of high levels of glucose or ethanol, and induced on minimal medium by the addition of yeast extract. A mutant deficient in FBP segregates independently of the ADHII structural gene locus. This phenomenon is of interest because of the discovery of Ciriacy [(1979) Mol. Gen. Genet. 176, 427-431] of mutants (ccr, or carbon catabolite repression) which repress both FBP and ADHII simultaneously, along with several other enzymes.Activity gel electrophoresisGluconeogenesisRegulatio
