The Scope and Methods of Citizen Participation in Planning and Designing Public library Facilities

A questionnaire survey was conducted to ascertain the scope and methods used to involve citizens in public library facility planning and design. Because of the paucity of written material on this subject in the literatures of both library science and architecture, this descriptive study was undertaken

Continuous sonochemical nanotransformation of lignin - process design and control

As the most abundant renewable aromatic polymer on the planet, lignin is gaining growing interest in replacing petroleum-based chemicals and products. However, only <5 % of industrial lignin waste is revalorized in its macromolecular form as additives, stabilizing agents or dispersant and surfactants. Herein, revalorization of this biomass was achieved by implementing an environmentally-friendly continuous sonochemical nano- transformation to obtain highly concentrated lignin nanoparticles (LigNPs) dispersions for added-value material applications. With the aim to further model and control a large-scale ultrasound-assisted lignin nano- transformation, a two-level factorial design of experiment (DoE) was implemented varying the ultrasound (US) amplitude, flow rate, and lignin concentration. Size and polydispersity measurements together with the UV–Vis spectra of lignin recorded at different time intervals of sonication allowed to monitor and understand the sonochemical process on a molecular level. The light scattering profile of sonicated lignin dispersions showed a significant particle size reduction in the first 20 min, followed by moderate particle size decrease below 700 nm until the end of the 2 h process. The response surface analysis (RSA) of the particle size data revealed that the lignin concentration and sonication time were the most important factors to achieve smaller NPs. From a mechanistic point of view, a strong impact of the particle–particle collisions due to sonication seems to be responsible for the decrease in particle size and homogenization of the particle distribution. Unexpectedly, a strong interaction between the flow rate and US amplitude on the particle size and nanotransformation efficiency was observed, yielding smaller LigNPs at high amplitude and low flow rate or vice versa. The data derived from the DoE were used to model and predict the size and polydispersity of the sonicated lignin. Furthermore, the use of the NPs spectral process trajectories calculated from the UV–Vis spectra showed similar RSA model as the dynamic light scattering (DLS) data and will potentially allow the in-line monitoring of the nanotransformation process.This research was funded by the European Union under the framework of the projects BIOMAT (H2020-953270) and rLightBioCom (HORIZON-101091691).

Developer Cyber Essentials:Trialling Interventions to Improve Development Security

A series of interventions costing less than two days’ total effort from a facilitator can significantly improve the software security of the products developed by teams in a wide range of companies. This report introduces this series of interventions, explains how they were derived from previous research in industry, and evaluates using Participative Action Research their effectiveness with software development teams in three widely-varied organisations

Recruiting the next generation of rural healthcare practitioners: the impact of an online mentoring program on career and educational goals in rural youth

Introduction: There is increasing recognition that encouraging and supporting rural youth to pursue healthcare careers could be a promising strategy for addressing shortages of rural healthcare practitioners. Although rural students in health science programs often return to their home communities to practice, they continue to be underrepresented in these programs. Geographic isolation and small community sizes create barriers to entry for rural students, including a lack of educational and outreach services and a smaller pool of role models with experience in pursuing health science careers. Online mentoring has the potential to overcome these barriers by connecting rural youth with experienced role models from outside their communities; therefore, we tested whether this type of intervention could be used to increase interest in and guide rural youth towards rural healthcare careers. Methods: From 2016 to 2020, our intervention, Rural eMentoring BC, matched 364 youth in rural British Columbia to near-peer mentors enrolled in health science programs. Through an online platform, dyads discussed career and educational options and pathways through a semistructured curriculum consisting of eight units. To determine the likelihood of mentees pursuing a career in rural health care after participating in the program, we deployed pre- and post-unit surveys that evaluated their interest in the following areas: healthcare careers, post-secondary education, working rurally, and finding allies. After completing the program, 209 mentees were invited to complete a program evaluation, which consisted of short-answer questions intended to capture their overall impressions of the program. Results: After completing the career exploration unit, 63 students (out of the 103 who completed the unit) indicated that they were interested in healthcare careers, compared to 37 before. However, students&#039; attitudes towards post-secondary education and finding allies did not change after completing those units, nor did their opinion of working rurally (although there was no unit dedicated to this topic). Encouragingly though, most already held positive opinions of these areas before entering the program. Of the 41 students who took our program evaluation, most viewed the program and their mentors favorably; discussion topics they found most useful included career exploration, learning life skills, and learning how to prepare for, and what to expect from, post-secondary education. Conclusion: This study suggests that online mentoring can direct rural youths&#039; career interests toward, and provide a refreshing approach to imparting information about, healthcare professions. Although its longitudinal impacts need to be studied, the changes in attitudes and gains in knowledge observed while participating in this program put these students on the right track for eventually transitioning to health science programs. Arming rural youth with the knowledge and motivation to pursue healthcare careers through near-peer mentorship could be a unique strategy for increasing rural student representation in health science programs, and ultimately the number of rural healthcare professionals

Association of television viewing with fasting and 2-h postchallenge plasma glucose levels in adults without diagnosed diabetes

Objectives: To investigate the association between change in daily step count and both adiposity and insulin sensitivity and the extent to which the association between change in daily step count and insulin sensitivity may be mediated by adiposity

Association of change in daily step count over five years with insulin sensitivity and adiposity: population based cohort study

Objectives: To investigate the association between change in daily step count and both adiposity and insulin sensitivity and the extent to which the association between change in daily step count and insulin sensitivity may be mediated by adiposity. Design: Population based cohort study. Setting: Tasmania, Australia. Participants: 592 adults (men (n=267), mean age 51.4 (SD 12.2) years; women (n=325), mean age 50.3 (12.3) years) who participated in the Tasmanian component of the national AusDiab Study in 2000 and 2005. Main outcome measures: Body mass index, waist to hip ratio, and HOMA insulin sensitivity at follow-up in 2005. Results: Over the five year period, the daily step count decreased for 65% (n=382) of participants. Having a higher daily step count in 2005 than in 2000 was independently associated with lower body mass index (0.08 (95% confidence interval 0.04 to 0.12) lower per 1000 steps), lower waist to hip ratio (0.15 (0.07 to 0.23) lower), and greater insulin sensitivity (1.38 (0.14 to 2.63) HOMA units higher) in 2005. The mean increase in HOMA units fell to 0.34 (-0.79 to 1.47) after adjustment for body mass index in 2005. Conclusions: Among community dwelling, middle aged adults, a higher daily step count at five year follow-up than at baseline was associated with better insulin sensitivity. This effect seems to be largely mediated through lower adiposity

Light-touch Interventions to Improve Software Development Security

Many software developers still have little interest in software security. To change this, we need ‘interventions’ to development teams to motivate and help them towards security improvement. An intervention costing less than two days’ effort from a facilitator plus half a day of team effort can significantly improve that team’s software security. This case study describes how this approach was used with one commercial team, and identifies its impact using Participative Action Research. With suitable improvements, the approach has the potential to help many other development teams

Interventions for Software Security:Creating a Lightweight Program of Assurance Techniques for Developers

Though some software development teams are highly effective at delivering security, others either do not care or do not have access to security experts to teach them how. Unfortunately, these latter teams are still responsible for the security of the systems they build: systems that are ever more important to ever more people. We propose that a series of lightweight interventions, six hours of facilitated workshops delivered over three months, can improve a team’s motivation to consider security and awareness of assurance techniques, changing its security culture even when no security experts are involved. The interventions were developed after an Appreciative Inquiry and Grounded Theory survey of security professionals to find out what approaches work best. They were then validated in fieldwork with a Participatory Action Research study that de-livered the workshops to three development organizations. This approach has the potential to be applied by many development teams, improving the security of software worldwide
