Picture This: Using photo-research exhibits as science outreach

Is a picture worth a thousand words? This paper discusses a unique science outreach initiative–provocative photo-research exhibits on sexism in science. Gender imbalance in science, technology, engineering, and math (STEM) is not only a concern from a social justice perspective, but also has negative consequences for scientific innovation and the economy, given that lack of workplace gender diversity is associated with lower revenue and returns. Science outreach (i.e., public outreach by scientists) could be particularly impactful in Waterloo, Ontario – a region known as ‘Canada’s Silicon Valley’ that contributes over $30-billion annually to the global economy. Portraying complex social issues using a visual medium has the potential to be accessible to a diverse audience. Images from two photo-research exhibits #DistractinglySexist (2015) and #DistractinglyHonest (2016) were based on social-psychological literature and findings from research by two of the authors (Hennessey and Foster) on the social costs of confronting sexism in science. Feedback indicates that these exhibits are effective outreach tools, and appear to facilitate discussions on sexism in science, and expand the social network of women in science by connecting those in the series and people who engage with exhibit materials

An alternative fit to Belle mass spectra for DD, D*D* and Lambda_C Lambda_c

Peaks observed by Belle in DD at 3.878 GeV and in D*D* at 4.156 GeV may be fitted by phase space multiplied by a form factor with an RMS radius of interaction 0.63 fm. The peak observed in Lambda_C Lambda_C at 4.63 GeV may be explained by Y(4660), multiplied by a corresponding form factor with RMS radius 0.94 fm.Comment: 3 pages, 1 figures Shorted version, conclusions unchange

Adverse infusion reactions to rituximab in systemic lupus erythematosus: a retrospective analysis

Background To undertake a retrospective review of patients with SLE who had received Rituximab in order to determine the rates and associated patient characteristics of clinically significant adverse infusion reactions. Methods A descriptive analysis was undertaken of each infusion reaction, which was then assessed using the clinical information available to hypothesise on the possible underlying mechanism(s). Results Records of 136 SLE patients previously treated with 481 individual infusions of Rituximab were reviewed. A total of 22 patients (17.6%) had 28 (5.8% of total infusions) documented clinically significant adverse infusion reactions. Average age at first Rituximab infusion in patients without a reaction was 37 years (range 16–73) compared with 30 years (range 18–56) in those with a reaction. A high proportion of men (18.2%) experienced an infusion reaction. Severity and type of reaction varied. 6.4% of those who had a reaction were not retreated. Conclusions While Rituximab remains an important tool in the treatment of SLE it is important to be aware that rates of infusion reactions may be more significant in SLE than in other diseases. A prospective study is required to better characterise the reactions

A Multiprocessor System for Performing Mail Sorting in Real Time

This paper describes a special purpose embedded multiprocessor architecture and algorithms developed for performmg real time Multi-Line Optical Character Recognition (MLOCR). MLOCR is a  computationally intensive real time application involving character image extraction, gray scale thresholding, rotation and scaling of individual characters, and character identification. The computational complexity of the algorithms implemented in the system required custom hardware in a parallel processing environment to meet the real time system requirements. The algorithms as well as the functional partitioning of the algorithms mto parallel processing subsystems are discussed

Birds surveyed in the harvested and unharvested areas of a reduced-impact logged forestry concession, located in the lowland subtropical humid forests of the Department of Santa Cruz, Bolivia.

As part of a larger study of reduced-impactlogging effects on bird community composition,we surveyed birds from December to Februaryduring the 2003-2004 wet-season within harvestedand unharvested blocks of the La Chonta forestryconcession, Department of Santa Cruz, Bolivia.The logged forest was harvested using reduced-impactlogging techniques between one and fouryears previously. During point count surveys, weidentified 5062 individual birds, belonging to 155species, and 33 families. We provide a list of birdspecies found within the harvested andunharvested blocks of the concession for thebenefit of other researchers assessing theresponses of Neotropical avifauna to disturbance,and to facilitate increased understanding of thediverse bird assemblages found within thelowland subtropical humid forests of Bolivia
