Does price really converge among provinces in Canada？ A study using unit root tests for cross-sectional panels

This paper examines price convergences across different provinces in Canada using 1983-2006 data. We adopt the new panel unit root tests for analysis that can correct for cross-sectional correlation. Our findings are contrary to previous studies and we conclude that intra-national price convergence does not occur. We also briefly discuss the reasons for the absence of convergence within Canada.     

Oxfam Australia's experience of ‘bottom–up’ accountability

Oxfam's experience suggests that ‘bottom–up’ accountability can be an important mechanism whereby men and women living in poverty can hold others to account. The first section of this article illustrates this with two examples of Oxfam experience in Vietnam and Sri Lanka. The second section draws out some of the lessons from these examples and attempts to situate them within the broader debate about approaches to accountability. In the third section some suggestions are put forward about what would need to change if active citizenship and ‘speaking truth to power’ were to become the renewed focus of accountability.     

新加坡的医疗保障体系

新加坡医疗保障体系以其投入低、效率高为世人所称道。文章介绍了新加坡医疗保障体系的筹资和医疗服务供给系统,并对其进行公平和效率评估,认为新加坡医疗体制的成功实际上并不能归功于医疗个人账户制度,而是源于其内设的对低收入者就医的补贴制度和个人自付费用对医疗服务消费的控制。     

The ‘Reasonable Man’, his Nineteenth‐century ‘Siblings’, and their Legacy

The reasonable man is the best known, but not the only, legal construct to be born into the nineteenth‐century common law. This article introduces the man's siblings – including those from the areas of trust law, criminal law, contract law, and intellectual property law (both patents and trademarks). The fact that some of these ‘men’ changed the law is not controversial; this research further highlights that while several of these came to life in that century, only some had a significant role into the twentieth century. Those that did are tied to the foundations of our society through their role in facilitating innovation and consumer protection. The argument is that it was the constructs’ nature and their capacity to accommodate public policy issues that enabled the vitality of the ‘reasonable person ‘ (negligence) and the ‘person skilled in the art’ (patents).     

Dyadic Representation in a Westminster System

Is policy representation in contemporary Westminster systems solely a function of programmatic national parties, or does the election of legislators via single‐member districts result in MPs whose policy positions are individually responsive to public opinion in their constituencies? We generate new measures of constituency opinion in Britain and show that, in three different policy domains and controlling for MP party, the observed legislative behavior of MPs is indeed responsive to constituency opinion. The level of responsiveness is moderate, but our results do suggest a constituency‐MP policy bond that operates in addition to the well‐known bond between voters and parties.     

Russia's Artificial Intelligence Strategy: The Role of State-Owned Firms

In 2017, Russian President Vladimir Putin declared that whichever country becomes the leader in artificial intelligence (AI) “will become the ruler of the world.” Yet Russia lags competitors like China and the United States substantially in AI capabilities. What is Russia's strategy for boosting development of AI technologies, and what role do groups within the Russian elite play in shaping this strategy? Russia's AI development strategy is unique in that it is led not by the government, nor by the private sector, but by state-owned firms. The government's distrust of Russia's largest tech firm, Yandex, has sidelined the company from national AI planning. Meanwhile, Russia's defense conglomerate Rostec publicly appears to focus less on artificial intelligence than on other high-tech priorities. As a result, Russia's AI development has been left to a state-owned bank, Sberbank, which has taken the lead in devising plans for government-backed investment in AI.     

A Randomized Trial of Probation Case Management for Drug-Involved Women Offenders

This paper reports findings from a clinical trial of a probation case management (PCM) intervention for drug-involved women offenders. Participants were randomly assigned to either PCM (n=92) or standard probation (n=91), and followed for 12 months using measures of substance abuse, psychiatric symptoms, social support and service utilization. Arrest data were collected from administrative datasets. The sample (N=183) included mostly African American (57%) and White (20%) women, with a mean age of 34.7 (SD = 9.2) and mean education of 11.6 years (SD = 2.1). Cocaine and heroin were the most frequently reported drugs of abuse, 86% reported prior history of incarceration, and 74% had children. Women assigned to both PCM and standard probation showed change over time in the direction of clinical improvement on 7 of 10 outcomes measured. However, changes observed for the PCM group were no different than those observed for the standard probation group. Higher levels of case management, drug abuse treatment, and probationary supervision may be required to achieve improved outcomes in this population.
