Energy, Trade and Geopolitics in Asia: The Implications for Canada

Canada’s growing interest in trade with countries in the Indo-Pacific region corresponds with an ominous growth in geopolitical instability and insecurity in that part of the globe. With Indo-Pacific hunger for oil expected to soar – especially in China, where demand will translate to 80 per cent of imports in 10 years – Canada needs to develop policies to deal with the region’s turbulent realities. The Indo-Pacific comprises countries in South Asia and Southeast Asia, and includes such unstable and unpredictable players as North Korea and Pakistan, both of which have nuclear weapons and long-simmering border tensions. India is an emerging economic and military rival to China. In the next 20 years, China and India are expected to lead the global demand for gas as coal consumption continues to decline, and Canada has a stake in this prosperous future. Along with territorial squabbles in the region, Canada will have to deal with complex issues such as terrorism, human trafficking, transnational crime, piracy and cyber-crime, as well as the struggle for global dominance between China and the U.S. One key area for potential conflict is China’s recent construction and militarization of artificial islands in the South China Sea. The Canadian government’s new military strategy, Strong, Secure, Engaged does little more than make a plea for peace and the rule of law in the South China Sea. However, more trade crosses the Pacific Ocean from Canada than crosses the Atlantic. And with Canada signing on to the Comprehensive and Progressive Trans-Pacific Partnership (CPTPP), the region’s troubles will need to be resolved by more than good intentions on paper. Canada must shift more diplomatic, security and military resources to the Indo-Pacific; otherwise, its efforts will be spread too thinly to be effective in the region. Trade, especially through a major route like the Strait of Malacca, could easily be disrupted by any one of a number of disputes, such as a conflict between China and Taiwan or if historic resentments boil over among competing territorial claimants in the region. Thus, Canada needs to step up and reaffirm its security commitments to the Association of Southeast Asian Nations (ASEAN) as a partner in the region. Participating in maritime exercises and Freedom of Navigation (FON) operations would also help to reinforce to countries in the region the importance of abiding by international law. Meanwhile, Canada should set aside for now any intentions to negotiate a free trade agreement with China. China does not share some of Canada’s key trade and security goals and its aggressive behaviour in the South and East China Seas clearly signal that now is not the time to talk about a trade pact. China must demonstrate that it is willing to take a more cooperative approach to resolving trade and security issues in the Indo-Pacific and to support and respect the rule of law in the region. Canada has the potential to become a reliable, stable source of energy for Indo-Pacific countries. There is also an opportunity for provinces such as Alberta to strike their own strategic deals to provide energy resources to countries in that region, in return for trade and investment benefits. However, while investing at home in the necessary infrastructure and export capability to expand its role, Canada must also strive to bring its own unique approach to enhancing regional and energy security in the Indo-Pacific

Spontaneous formation of optically induced surface relief gratings

A model based on Fick's law of diffusion as a phenomenological description of the molecular motion, and on the coupled mode theory, is developped to describe single-beam surface relief grating formation in azopolymers thin films. It allows to explain the mechanism of spontaneous patterning, and self-organization. It allows also to compute the surface relief profile and its evolution in time with good agreement with experiments

Utility of the MMPI–2-RF (Restructured Form) Validity Scales in Detecting Malingering in a Criminal Forensic Setting: A Known-Groups Design

The current study examined the utility of the recently released Minnesota Multiphasic Personality Inventory—2 Restructured Form (MMPI–2-RF; Ben-Porath & Tellegen, 2008) validity scales to detect feigned psychopathology in a criminal forensic setting. We used a known-groups design with the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) as the external criterion to determine groups of probable malingering versus nonmalingering. A final sample of 125 criminal defendants, who were administered both the SIRS and the MMPI–2-RF during their evaluations, was examined. The results indicated that the two MMPI–2-RF validity scales specifically designed to detect overreported psychopathology, F-r and FP-r, best differentiated between the malingering and nonmalingering groups. These scales added incremental predictive utility to one another in this differentiation. Classification accuracy statistics substantiated the recommended cut scores in the MMPI–2-RF manual (Ben-Porath & Tellegen, 2008) in this forensic setting. Implications for these results in terms of forensic assessment and detection of malingering are discussed. DOI: 10.1037/a001822

Canalization of the evolutionary trajectory of the human influenza virus

Since its emergence in 1968, influenza A (H3N2) has evolved extensively in genotype and antigenic phenotype. Antigenic evolution occurs in the context of a two-dimensional 'antigenic map', while genetic evolution shows a characteristic ladder-like genealogical tree. Here, we use a large-scale individual-based model to show that evolution in a Euclidean antigenic space provides a remarkable correspondence between model behavior and the epidemiological, antigenic, genealogical and geographic patterns observed in influenza virus. We find that evolution away from existing human immunity results in rapid population turnover in the influenza virus and that this population turnover occurs primarily along a single antigenic axis. Thus, selective dynamics induce a canalized evolutionary trajectory, in which the evolutionary fate of the influenza population is surprisingly repeatable and hence, in theory, predictable.Comment: 29 pages, 5 figures, 10 supporting figure

The challenges of modeling and forecasting the spread of COVID-19

The coronavirus disease 2019 (COVID-19) pandemic has placed epidemic modeling at the forefront of worldwide public policy making. Nonetheless, modeling and forecasting the spread of COVID-19 remains a challenge. Here, we detail three regional-scale models for forecasting and assessing the course of the pandemic. This work demonstrates the utility of parsimonious models for early-time data and provides an accessible framework for generating policy-relevant insights into its course. We show how these models can be connected to each other and to time series data for a particular region. Capable of measuring and forecasting the impacts of social distancing, these models highlight the dangers of relaxing nonpharmaceutical public health interventions in the absence of a vaccine or antiviral therapies

Trump vs. Hillary: What went Viral during the 2016 US Presidential Election

In this paper, we present quantitative and qualitative analysis of the top retweeted tweets (viral tweets) pertaining to the US presidential elections from September 1, 2016 to Election Day on November 8, 2016. For everyday, we tagged the top 50 most retweeted tweets as supporting or attacking either candidate or as neutral/irrelevant. Then we analyzed the tweets in each class for: general trends and statistics; the most frequently used hashtags, terms, and locations; the most retweeted accounts and tweets; and the most shared news and links. In all we analyzed the 3,450 most viral tweets that grabbed the most attention during the US election and were retweeted in total 26.3 million times accounting over 40% of the total tweet volume pertaining to the US election in the aforementioned period. Our analysis of the tweets highlights some of the differences between the social media strategies of both candidates, the penetration of their messages, and the potential effect of attacks on bothComment: Paper to appear in Springer SocInfo 201

An open source tool to infer epidemiological and immunological dynamics from serological data: Serosolver

We present a flexible, open source R package designed to obtain biological and epidemiological insights from serological datasets. Characterising past exposures for multi-strain pathogens poses a specific statistical challenge: observed antibody responses measured in serological assays depend on multiple unobserved prior infections that produce cross-reactive antibody responses. We provide a general modelling framework to jointly infer infection histories and describe immune responses generated by these infections using antibody titres against current and historical strains. We do this by linking latent infection dynamics with a mechanistic model of antibody kinetics that generates expected antibody titres over time. Our aim is to provide a flexible package to identify infection histories that can be applied to a range of pathogens. We present two case studies to illustrate how our model can infer key immunological parameters, such as antibody titre boosting, waning and crossreaction, as well as latent epidemiological processes such as attack rates and age-stratified infection risk

School's Out: Seasonal Variation in the Movement Patterns of School Children.

School children are core groups in the transmission of many common infectious diseases, and are likely to play a key role in the spatial dispersal of disease across multiple scales. However, there is currently little detailed information about the spatial movements of this epidemiologically important age group. To address this knowledge gap, we collaborated with eight secondary schools to conduct a survey of movement patterns of school pupils in primary and secondary schools in the United Kingdom. We found evidence of a significant change in behaviour between term time and holidays, with term time weekdays characterised by predominately local movements, and holidays seeing much broader variation in travel patterns. Studies that use mathematical models to examine epidemic transmission and control often use adult commuting data as a proxy for population movements. We show that while these data share some features with the movement patterns reported by school children, there are some crucial differences between the movements of children and adult commuters during both term-time and holidays.AJK was supported by the Medical Research Council (fellowship MR/K021524/1, http://www.mrc.ac.uk/) and the RAPIDD program of the Science & Technology Directorate, Department of Homeland Security, and the Fogarty International Center, National Institutes of Health (http://www.fic.nih.gov/about/staff/pages​/epidemiology-population.aspx#rapidd).
