Online Monitoring Perceptions of North Texas HR Managers

With businesses losing billions to computer crime and employees wasting considerable time on their computers looking at sports updates, the latest fashion trends, and even less appropriate websites, businesses are cracking down by monitoring their employees. The efforts are to ultimately reduce scams, identify theft, computer crimes, fraud, sexual abuse, piracy, and threats. As a result, many businesses have resorted to online monitoring of their workplace computers. In this context, we look at how human resources (HR) professionals see three aspects of online monitoring. First, how do they view the discipline managers provideemployees based on what they see about them on the Internet? Second, how do HR managers view employee handbook online monitoring policies? Should employees be permitted to freely use their computers, have certain constraints, or have all private use banned

A novel spatio-temporal examination of children\u27s accessibility, exposure, and engagement to parks and recreation spaces in Middlesex-London, Ontario

Children are spending more free time engaged in activities indoors, rather than in outdoor environments such as parks and recreation spaces. Parks and recreation spaces provide amenities that promote physical, cognitive, and social health among children. As it relates to the complexities of children’s living situations, properly measuring children’s levels of interactions with these spaces is poorly understood in geography research. By examining various attributes of children, this thesis improves on the measurement of children’s levels of interactions with parks and recreation spaces. Research herein utilized household survey data, a high-resolution GIS dataset of environmental factors, and GPS logs from participants ages 9-14 years recruited throughout southwestern Ontario for a mixed-methods project conducted in 2010-2013. Sociodemographic characteristics acquired from the survey and GPS tracks of the participants were linked to the GIS dataset, which included regional parks-and-recreation geospatial data. To compare measures for estimating levels of interactions with parks and recreation spaces, the merged dataset was examined through an Accessibility-Exposure-Engagement framework. Statistical tests revealed relationships between children’s home locations or sociodemographic characteristics, and levels of accessibility/exposure/engagement with specific parks and recreation amenities. Hierarchical regression modelling, with blocks containing sociodemographic variables, assessed the influence of individual, interpersonal, social, and built-environment characteristics on children’s proportion of free time in parks and recreation spaces. Results suggest measures of home location’s proximity to parks and recreation spaces do not represent frequency of exposure or duration of engagement to them by children. Child gender, visible minority status, and urbanicity are associated with proportion of free time in parks and recreation spaces. Moving forward, geography research should utilize the most accurate methods for estimating children’s levels of interactions with health-positive environments such as parks and recreation spaces

Aquaculture: a rapidly growing and significant source of sustainable food? Status, transitions and potential

The status and potential of aquaculture is considered as part of a broader food landscape of wild aquatic and terrestrial food sources. The rationale and resource base required for the development of aquaculture are considered in the context of broader societal development, cultural preferences and human needs. Attention is drawn to the uneven development and current importance of aquaculture globally as well as its considerable heterogeneity of form and function compared with established terrestrial livestock production. The recent drivers of growth in demand and production are examined and the persistent linkages between exploitation of wild stocks, full life cycle culture and the various intermediate forms explored. An emergent trend for sourcing aquaculture feeds from alternatives to marine ingredients is described and the implications for the sector with rapidly growing feed needs discussed. The rise of non-conventional and innovative feed ingredients, often shared with terrestrial livestock, are considered, including aquaculture itself becoming a major source of marine ingredients. The implications for the continued expected growth of aquaculture are set in the context of sustainable intensification, with the challenges that conventional intensification and emergent integration within, and between, value chains explored. The review concludes with a consideration of the implications for dependent livelihoods and projections for various futures based on limited resources but growing demand

Physical activity and social connectedness interventions in outdoor spaces among children and youth: A rapid review

Introduction: The rise in sedentary behaviour, coupled with the decline in overall mental health among Canadian children and youth in recent decades, demonstrates a clear need for applied research that focusses on developing and evaluating cross-disciplinary interventions. Outdoor spaces provide opportunities for physical activity and social connectedness, making them an ideal setting to address these critical health concerns among children and youth. Methods: We conducted a rapid review of peer-reviewed (n = 3096) and grey literature (n = 7) to identify physical activity and/or social connectedness outdoor space interventions targeted at children and youth (19 years and under) in Australia and New Zealand, Canada, Europe and the United States. We determined if interventions were effective by analyzing their research design, confidence intervals and reported limitations, and then conducted a narrative synthesis of the effective interventions. Results: We found 104 unique studies, of which 70 (67%) were determined to be effective. Overall, 55 interventions targeted physical activity outcomes, 10 targeted social connectedness outcomes and 5 targeted both. Play (n = 47) and contact with nature (n = 25) were dominant themes across interventions, with most taking place in a school or park. We report on the identifying features, limitations and implications of these interventions. Conclusion: The incorporation of natural and play-focussed elements into outdoor spaces may be effective ways to improve physical activity and social connectedness. There is a considerable need for more Canadian-specific research. Novel methods, such as incorporating smartphone technology into the design and evaluation of these interventions, warrant consideration

A review of inclusive business models and their application in aquaculture development

For aquaculture to continue along its current growth trajectory and contribute towards achieving the Sustainable Development Goals, value chains must become more inclusive. Smallholders and other local value chain actors are often constrained by circumstances and market failures in the global aquaculture industry. Integrating these actors into aquaculture value chains through inclusive business models (IBMs) is often touted as a solution to sustainable and ethical trade and business that can generate development outcomes. We reviewed 36 papers under seven business models commonly used in agriculture development to assess their application in aquaculture value chains in lower‐income countries. A global value chain (GVC) analysis is used to unpack the economic and social upgrading objectives of the different IBMs, as well as the types of relational coordination used between actors in the chain to achieve development outcomes. The extent to which these IBMs helped poor actors overcome certain barriers is evaluated with a focus on how they may ensure or be a risk to inclusiveness through the relations and upgrading opportunities evident in their make‐up. The analysis found that the majority of the models focused on economic upgrading over social upgrading. Providing opportunities for the latter is key to achieving the inclusive objectives of IBMs. Greater horizontal coordination between actors can create further opportunities for economic upgrading established under vertical coordination with other nodes upstream and downstream in a value chain. There is a need to further contextualize these models to aquaculture systems and develop clear indicators of inclusiveness

Systematic meta-analyses and field synopsis of genetic association studies in colorectal adenomas

BackgroundLow penetrance genetic variants, primarily single nucleotide polymorphisms, have substantial influence on colorectal cancer (CRC) susceptibility. Most CRCs develop from colorectal adenomas (CRA). Here we report the first comprehensive field synopsis that catalogues all genetic association studies on CRA, with a parallel online database [http://www.chs.med.ed.ac.uk/CRAgene/].MethodsWe performed a systematic review, reviewing 9750 titles, and then extracted data from 130 publications reporting on 181 polymorphisms in 74 genes. We conducted meta-analyses to derive summary effect estimates for 37 polymorphisms in 26 genes. We applied the Venice criteria and Bayesian False Discovery Probability (BFDP) to assess the levels of the credibility of associations.ResultsWe considered the association with the rs6983267 variant at 8q24 as 'highly credible', reaching genome-wide statistical significance in at least one meta-analysis model. We identified 'less credible' associations (higher heterogeneity, lower statistical power, BFDP > 0.02) with a further four variants of four independent genes: MTHFR c.677C>T p.A222V (rs1801133), TP53 c.215C>G p.R72P (rs1042522), NQO1 c.559C>T p.P187S (rs1800566), and NAT1 alleles imputed as fast acetylator genotypes. For the remaining 32 variants of 22 genes for which positive associations with CRA risk have been previously reported, the meta-analyses revealed no credible evidence to support these as true associations.ConclusionsThe limited number of credible associations between low penetrance genetic variants and CRA reflects the lower volume of evidence and associated lack of statistical power to detect associations of the magnitude typically observed for genetic variants and chronic diseases. The CRA gene database provides context for CRA genetic association data and will help inform future research directions
