    Photography within the construction industry is merging into a new form of image capture and output that is a mix of conventional photography and digital imagery. As this transition takes place it is anticipated that the credibility of the image may also change within in the communication chain that links the various disciplines within the building industry. The following paper presents the development and results of a pilot survey of building professionals, which addresses the quality, content and authenticity of both conventional photography and digitally produced images used within the construction industry.<br /

    An examination of the integrated cognitive affective model and weight regain in obesity: a pilot study

    Obesity is a complex health issue that is widely considered to be an epidemic in North America. University-based weight loss programs produce weight loss in the shortterm, but obesity tends to be a chronic condition that is difficult to treat due to long-term weight regain. The majority of obese people who lose weight tend to regain a large proportion, if not all, of the lost weight within one year. Among non-regainers, long-term adherence to reduced-calorie diets and high levels of exercise are associated with better outcomes. However, weight regain is the norm. Preliminary evidence suggests that psychological factors may play into why some people regain weight. The Integrative Cognitive Affective Therapy [ICAT] model provides a framework for understanding how certain psychological factors may be associated with weight regain including selfdiscrepancy, mood states (i.e., depression, anxiety, and stress), emotion regulation, and emotional eating. The current study examined the application of the ICAT model to explain weight regain in obesity. A community sample of 71 obese adults who had recently lost at least 5% of their body weight were included in the analysis. At baseline, weight was measured, participants completed self-report questionnaires of psychological variables including: self-discrepancy, mood, difficulty in emotion regulation, emotional eating, and binge eating. Participants then provided self-reported weight at 3-month follow-up, and had their weight re-measured at 6-month follow-up. Results provided evidence that higher baseline self-discrepancy and difficulty in emotion regulation were related to worse baseline depression and anxiety. Higher baseline emotional eating was related to higher body mass index (BMI) at baseline, 3-, and 6-month follow-up. On average, BMI did not change significantly from baseline to 6- month follow-up. However, upon closer inspection, about one third of the sample regained weight (31.4%) while the remainder (68.6%) continued to lose weight between baseline and 6-months. Regression analyses revealed that none of the psychological variables measured at baseline significantly predicted BMI change from baseline to 6- months, and there were no significant differences between weight regainers and nonregainers on any of the baseline psychological variables including self-discrepancy, negative mood states, difficulties with emotion regulation, emotional eating, or binge eating. This research contributed to the literature by exploring the role of psychological factors in explaining weight regain in obesity, and provided an initial exploration of the ICAT model as a framework for understanding weight regain. The implications of the findings, directions for future research as well as study strengths and limitations are discussed

    Project Prairie and Tallgrass Education on the Rice Lake Plains: A Journey from 1870 to Today and Beyond

    Project Prairie began in 2011 as a curriculum-linked integrated environmental studies program to showcase the Rice Lake Plains (RLP), a tallgrass prairie landscape of sandy rolling hills located at the eastern extent of the Oak Ridges Moraine in southern Ontario. Project Prairie provides educators both indoor and outdoor activities that support their curriculum and share the story of the RLP. Project Prairie provides teacher and student resources that focus on the RLP from the mid-nineteenth century to present day. Learning objectives of Project Prairie are developed from the subjects of science, social science, language arts, geography, history, and Aboriginal culture. Additional educational resources that have been produced include a puppet show, maps, an educational booklet with poster, species at risk cards, species at risk booklet, magnets, and a website. The curriculum material can be used on smart boards, thereby giving students the most up-to-date educational experience. Project Prairie grew from successful work completed by Alderville First Nation Black Oak Savanna (ABOS) and other partners in the Rice lake Plains Joint Initiative (RLPJI). The Nature Conservancy of Canada (NCC) forged the multi-partner RLPJI in 2002 to raise awareness and work collaboratively to restore tallgrass prairie and savanna habitats on a landscape scale. To date, the partnership has grown to ten organizations that help deliver Project Prairie to students across the RLP

    Architectural photography is merging into a new form of image capture and output which is a mix of conventional photography and digital imagery. As this transition takes place it is anticipated that the credibility of the image may also change. the aim of the project is to research the perception of the quality, content and authenticity of both conventional photography and digitally produced images used within the architectural profession

    Comparative genomics-based investigation of resequencing targets in Vibrio fischeri: Focus on point miscalls and artefactual expansions

    <p>Abstract</p> <p>Background</p> <p>Sequence closure often represents the end-point of a genome project, without a system in place for subsequent improvement and refinement. Building on the genome project of <it>Vibrio fischeri </it>ES114, we used a comparative approach to identify and investigate genes that had a high likelihood of sequence error.</p> <p>Results</p> <p>Comparison of the <it>V. fischeri </it>ES114 genome with that of conspecific strain MJ11 identified 82 target loci in ES114 as containing likely errors, and thus of high-priority for resequencing. Analysis of the targets identified 75 loci in which an error had occurred, resulting in the correction of 10,457 base pairs to generate the new ES114 genomic sequence. A majority of the inaccurate loci involved frameshift errors, correction of which fused adjacent ORFs. Although insertions/deletions are thought to be rare in microbial genome assemblies, fourteen of the loci contained extraneous sequence of over 300 bp, likely due to imperfect contig ends that were misassembled in tandem rather than as overlapping segments. Additionally we updated the entire genome annotation with 113 new features including previously uncalled protein-coding genes, regulatory RNA genes and operon leader peptides, and we analyzed the transcriptional apparatus encoded by ES114.</p> <p>Conclusion</p> <p>We demonstrate that errors in microbial genome sequences, thought to largely be confined to point mutations, may also consist of other prevalent large-scale rearrangements such as insertions. Ongoing genome quality control and annotation programs are necessary to accompany technological advancements in data generation. These updates further advance <it>V. fischeri </it>as an important model for understanding intercellular communication and colonization of animal tissue.</p
