What motivates political actors with diverging interests to respect the Supreme Court's authority? A popular answer is that the public serves as the guardian of judicial independence by punishing elected officials who undermine the justices. Curbing the Court challenges this claim, presenting a new theory of how we perceive the Supreme Court. Bartels and Johnston argue that, contrary to conventional wisdom, citizens are not principled defenders of the judiciary. Instead, they seek to limit the Court's power when it suits their political aims, and this inclination is heightened during times of sharp partisan polarization. Backed by a wealth of observational and experimental data, Bartels and Johnston push the conceptual, theoretical, and empirical boundaries of the study of public opinion of the courts. By connecting citizens to the strategic behavior of elites, this book offers fresh insights into the vulnerability of judicial institutions in an increasingly contentious era of American politics.
Understanding the distribution, abundance and habitat preferences of species in the Southern Ocean provides a foundation for assessing the impacts of environmental change and anthropogenic disturbance on Antarctic ecosystems. In near-shore waters at Casey and Davis Stations, photoquadrat surveys were used to determine sea anemone distribution and abundance, habitat preferences, associations with other species and the impact of human disturbance on sea anemone distribution. Two distinct sea anemone morphotypes were found in this study: large sea anemones that require hard substrate for attachment and small, burrowing sea anemones found in muddy sediment. The large sea anemones were found in rocky habitats, with the exception of some sedimentary habitats where other biota were used as substrate. The large sea anemones were associated with a diverse community of epibenthic species found in rocky habitats. The burrowing sea anemones were associated with a less diverse assemblage of sediment-dwelling epibenthos. At Casey Station, sea anemones were more abundant in habitats adjacent to a former waste disposal site than at control sites. The reason for this is not yet known, but may be due to high organic matter inputs or, alternatively, a longer sea ice duration providing protection from ice scour.
Yukon Territory (YT) is a remote region in northern Canada with ongoing spread of tuberculosis (TB). To explore the utility of whole genome sequencing (WGS) for TB surveillance and monitoring in a setting with detailed contact tracing and interview data, we used a mixed-methods approach. Our analysis included all culture-confirmed cases in YT (2005–2014) and incorporated data from 24-locus Mycobacterial Interspersed Repetitive Units-Variable Number of Tandem Repeats (MIRU-VNTR) genotyping, WGS and contact tracing. We compared field-based (contact investigation (CI) data + MIRU-VNTR) and genomic-based (WGS + MIRU-VNTR + basic case data) investigations to identify the most likely source of each person's TB and assessed the knowledge, attitudes and practices of programme personnel around genotyping and genomics using online, multiple-choice surveys (n = 4) and an in-person group interview (n = 5). Field- and genomics-based approaches agreed for 26 of 32 (81%) cases on likely location of TB acquisition. There was less agreement in the identification of specific source cases (13/22 or 59% of cases). Single-locus MIRU-VNTR variants and limited genetic diversity complicated the analysis. Qualitative data indicated that participants viewed genomic epidemiology as a useful tool to streamline investigations, particularly in differentiating latent TB reactivation from the recent transmission. Based on this, genomic data could be used to enhance CIs, focus resources, target interventions and aid in TB programme evaluation.
The paper demonstrates how the evolution of international law on colonial and indigenous peoples, in particular evolving rights to sovereignty over natural resources, shaped the changing relationship between Greenland and the rest of the Danish Realm. Greenland today is in a unique position in international law, enjoying an extremely high degree of self-government. This paper explores the history, current status and future of Greenland through the lens of international law, to show how international obligations both colour its relationship with the Kingdom of Denmark and influence its approaches to resource development internally. It considers the invisibility of the Inuit population in the 1933 Eastern Greenland case that secured Danish sovereignty over the entire territory. It then turns to Denmark’s registration of Greenland as a non-self-governing territory (colony) in 1946 before Greenland’s-purported decolonisation in 1953 and the deficiencies of that process. In the second part of the 20th century, Denmark began to recognise the Greenland Inuit as an indigenous people before a gradual shift towards recognition of the Greenlanders as a people in international law, entitled to self-determination, including the right to permanent sovereignty over their natural resources. This peaked with the Self-Government Act of 2009. The paper will then go on to assess competing interpretations of the Self-Government Act of 2009 according to which the Greenland self-government is the relevant decision-making body for an increasing number of fields of competence including, since 1 January 2010, the governance of extractive industries. Some, including members of the Greenland self-government, argue that the Self-Government Act constitutes full implementation of the UN Declaration on the Rights of Indigenous Peoples (UNDRIP 2007), but this view is not universally shared. The paper also considers the status and rights of two Greenland minorities: the North Greenlanders (Inughuit) and the East Greenlanders, each of whom has distinct histories, experiences of colonisation, dialects (or languages) and cultural traditions. While the Kingdom of Denmark accepts the existence of only one indigenous people, namely, the Inuit of Greenland, this view is increasingly being challenged in international fora, including the UN human rights treaty bodies, as the two minorities are in some cases considered distinct indigenous peoples. Their current position in Greenland as well as in a future fully independent Greenland is examined, and the rights that they hold against the Greenland self-government as well as the Kingdom of Denmark explored. Greenland’s domestic regime for governance of non-renewable natural resources (principally mining and hydrocarbons) is briefly analysed and compared with international standards, with a particular emphasis on public participation. The paper assesses the extent to which it complies with the standards in key international instruments.
When I was asked to serve as Governor General of Canada, I discovered I had much to relearn. Despite my background as a law student, professor, and dean, I had to revisit the legal principles and conventions of our constitution, especially as they relate to the authority and function of the Crown in Canada. My re-education enabled me to develop an even deeper admiration for how precious the rule of law is in our country, how thin and vulnerable its veneer can be, and how vital it is in moving closer to justice. Even more, my re-education revealed for me anew that the study and practice of law is a hollow pursuit if we do not use it to strive toward justice.
This chapter draws on research into the lives and prison experiences of around 650 male and female convicts who were released on licence (an early form of parole) from sentences of long-term imprisonment in England in the mid- to late nineteenth century. While both men and women were overwhelmingly committed to the convict system for larceny, their treatment differed significantly. The vast majority of convicts were released early on licence from their prison terms, even those committing very serious offences. However, female offenders were released slightly earlier and under different conditions than men. Having offended against their gender as well as society, more moral rehabilitation was deemed necessary for deviant women than for men, leading to requirements such as entering refuges or shelters. Female convicts’ internment in these institutions after being granted a licence reveals the impact of gender expectations on female prisoners in England.
Epidemiologic studies suggest that consumption of potatoes is associated with increased risk of cardiometabolic diseases. However, few clinical trials have empirically tested these observational findings. The aim of this single-blind, randomized, crossover study was to evaluate the effect of daily potato consumption, compared to refined grains, on risk factors for cardiometabolic diseases. It was hypothesized that no difference in cardiometabolic endpoints would be detected between conditions, but diet quality would improve with potato consumption. Healthy participants on self-selected diets received one potato-based side dish or one refined grain-based side dish daily, for four weeks, separated by a minimum two-week break. Dishes were isocaloric, carbohydrate-matched, and prepared without excess saturated fat or sodium. Participants were instructed to consume the side-dish with a meal in place of carbohydrates habitually consumed. Lipids/lipoproteins, markers of glycemic control, blood pressure (BP), weight and pulse wave velocity (PWV) were measured at baseline and condition endpoints. Diet quality was calculated, based on 24-hour recalls, using the Healthy Eating Index (HEI)-2015. Fifty adults (female n=34; age: 40±13; BMI: 24.5±3.6 kg/m2) completed this study. No between-condition differences were detected for fasting plasma glucose (-0.97; mg/dL, 95% CI: -2.3, 0.35; p=0.15), the primary outcome, or any other outcomes. Compared with refined grains, the HEI-2015 score (3.5, 95%CI: 0.6, 6.4 p=0.01), potassium (547 mg, 95%CI: 331, 764, p<0.001) and fiber (2.4 g, 95% CI: 0.6, 4.2, p=0.01) were higher following the potato condition. Consuming non-fried potatoes resulted in higher diet quality, potassium and fiber intake, without adversely affecting cardiometabolic risk.
In Republic 8–9, Socrates describes four main kinds of vicious people, all of whose souls are “ruled” by an element other than reason, and in some of whom reason is said to be “enslaved.” What role does reason play in such souls? In this paper, I argue, based on Republic 8–9 and related passages, and in contrast to some common alternative views, that for Plato the “enslavement” of reason consists in this: instead of determining for itself what is good, reason is forced to desire and pursue as good a goal determined by the soul’s ruler.
The global population is ageing and the likelihood of living alone increases with age. Services are necessary to help older people living alone to optimise health and wellbeing. This systematic review aimed to summarise the effectiveness and accessibility of interventions to improve the health and wellbeing of older people living alone. Relevant electronic databases (CINAHL, MEDLINE, PsycINFO and Scopus) were searched for all years up to August 2018. Studies were included if they involved older people (aged ⩾55 years) living alone, and an intervention with measured health and wellbeing outcomes. All study types were included. The Theory of Access was used to assess interventions across dimensions of accessibility, availability, acceptability, affordability, adequacy and awareness. Twenty-eight studies met the eligibility criteria; 17 studies focused on ageing safely in place and 11 on psychological and social wellbeing. Studies comprised quantitative (N = 19), qualitative (N = 4) and mixed-methods (N = 5) approaches. Dimensions from the Theory of Access were poorly addressed in the studies, particularly those of higher-quality methodology. Studies were heterogeneous, preliminary in scope and lacked consistent study design, methodology or measurement. Services that do not address user accessibility in design or evaluation may be limited in their uptake and impact. It is recommended that dimensions of access and co-creation principles be integrated into service design processes and be evaluated alongside clinical effectiveness.
As consumer-directed care programmes become increasingly common in aged care provision, there is a heightened requirement for literature summarising the experience and perspectives of recipients. We conducted rapid evidence reviews on two components of consumer experience of home- and community-based aged care: (a) drivers of choice when looking for a service (Question 1 (Q1)); and (b) perceptions of quality of services (Question 2 (Q2)). We systematically searched MEDLINE and EMBASE databases, and conducted manual (non-systematic) searches of primary and grey literature (e.g. government reports) across CINAHL, Scopus, PsychINFO, and Web of Science, Trove and OpenGrey databases. Articles deemed eligible after abstract/full-text screening subsequently underwent risk-of-bias assessment to ensure their quality. The final included studies (Q1: N = 21; Q2: N = 19) comprised both quantitative and qualitative articles, which highlighted that consumer choices of services are driven by a combination of: desire for flexibility in service provision; optimising mobility; need for personal assistance, security and safety, interaction, and social/leisure activities; and to target and address previously unmet needs. Similarly, consumer perspectives of quality include control and autonomy, interpersonal interactions, flexibility of choice, and safety and affordability. Our reviews suggest that future model development should take into account consumers’ freedom to choose services in a flexible manner, and the value they place on interpersonal relationships and social interaction.
The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low-frequency (80–300 MHz) southern sky. Since beginning operations in mid-2013, the MWA has opened a new observational window in the southern hemisphere enabling many science areas. The driving science objectives of the original design were to observe 21 cm radiation from the Epoch of Reionisation (EoR), explore the radio time domain, perform Galactic and extragalactic surveys, and monitor solar, heliospheric, and ionospheric phenomena. All together
programs recorded 20 000 h producing 146 papers to date. In 2016, the telescope underwent a major upgrade resulting in alternating compact and extended configurations. Other upgrades, including digital back-ends and a rapid-response triggering system, have been developed since the original array was commissioned. In this paper, we review the major results from the prior operation of the MWA and then discuss the new science paths enabled by the improved capabilities. We group these science opportunities by the four original science themes but also include ideas for directions outside these categories.
This chapter shows that the UK relies on information disclosure and market forces to steer companies towards greater sustainability, leaving company law and corporate governance largely free to focus on shareholder value. It traces the twentieth century regulatory and policy changes which reoriented the UK’s system from managerialist to shareholder-centric, before analysing the 2006 reforms, which are supposed to promote ‘enlightened shareholder value’ through directors’ duties and disclosure. Finally, the chapter considers recent developments that attempt to use information disclosure to promote a long-term approach, including giving shareholders stewardship responsibilities and a ‘say on pay’, making changes to takeover regulation, and requiring companies to make disclosures in relation to modern slavery. None of these recent measures have been successful, and the chapter concludes that far-reaching reforms to corporate governance are urgently needed.
This paper presents a numerical approach to predict the thermal residual stresses in polymer nanocomposites reinforced with a periodic array of wavy carbon nanotubes. A three dimensional unit cell model is established to accurately account for the waviness of the nanotube. Periodic boundary conditions are determined for the unit cell with a pair of curved surfaces. Appropriate methods to evaluate the macroscopic stresses and strains are also determined for the unit cell model in which the interior pores of the nanotubes are explicitly included. It is demonstrated that the macroscopic behavior of the nanocomposites is orthotropic due to the symmetries manifested. By employing material properties of the two constituents, the thermal residual stresses and strains induced by high temperature curing and cooling-down are predicted for an epoxy/wavy-nanotube composite. It is also demonstrated that the curing process tends to increase the waviness of the nanotube and the waviness has a significant influence on the distribution of the microscopic residual stresses.
Interfacility patient movement plays an important role in the dissemination of antimicrobial-resistant organisms throughout healthcare systems. We evaluated how 3 alternative measures of interfacility patient sharing were associated with C. difficile infection incidence in Ontario acute-care facilities.
The cohort included adult acute-care facility stays of ≥3 days between April 2003 and March 2016. We measured 3 facility-level metrics of patient sharing: general patient importation, incidence-weighted patient importation, and C. difficile case importation. Each of the 3 patient-sharing metrics were examined against the incidence of C. difficile infection in the facility per 1,000 stays, using Poisson regression models.
The analyzed cohort included 6.70 million stays at risk of C. difficile infection across 120 facilities. Over the 13-year period, we included 62,189 new cases of healthcare-associated CDI (incidence, 9.3 per 1,000 stays). After adjustment for facility characteristics, general importation was not strongly associated with C. difficile infection incidence (risk ratio [RR] per doubling, 1.10; 95% confidence interval [CI], 0.97–1.24; proportional change in variance [PCV], −2.0%). Incidence-weighted (RR per doubling, 1.18; 95% CI, 1.06–1.30; PCV, −8.4%) and C. difficile case importation (RR per doubling, 1.43; 95% CI, 1.29–1.58; PCV, −30.1%) were strongly associated with C. difficile infection incidence.
In this 13-year study of acute-care facilities in Ontario, interfacility variation in C. difficile infection incidence was associated with importation of patients from other high-incidence acute-care facilities or specifically of patients with a recent history of C. difficile infection. Regional infection control strategies should consider the potential impact of importation of patients at high risk of C. difficile shedding from outside facilities.
We have detected 27 new supernova remnants (SNRs) using a new data release of the GLEAM survey from the Murchison Widefield Array telescope, including the lowest surface brightness SNR ever detected, G 0.1 – 9.7. Our method uses spectral fitting to the radio continuum to derive spectral indices for 26/27 candidates, and our low-frequency observations probe a steeper spectrum population than previously discovered. None of the candidates have coincident WISE mid-IR emission, further showing that the emission is non-thermal. Using pulsar associations we derive physical properties for six candidate SNRs, finding G 0.1 – 9.7 may be younger than 10 kyr. Sixty per cent of the candidates subtend areas larger than 0.2 deg2 on the sky, compared to < 25% of previously detected SNRs. We also make the first detection of two SNRs in the Galactic longitude range 220°–240°.
This work makes available a further
of the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey, covering half of the accessible galactic plane, across 20 frequency bands sampling 72–231 MHz, with resolution
. Unlike previous GLEAM data releases, we used multi-scale CLEAN to better deconvolve large-scale galactic structure. For the galactic longitude ranges
$345^\circ < l < 67^\circ$
$180^\circ < l < 240^\circ$
, we provide a compact source catalogue of 22 037 components selected from a 60-MHz bandwidth image centred at 200 MHz, with RMS noise
and position accuracy better than 2 arcsec. The catalogue has a completeness of 50% at
, and a reliability of 99.86%. It covers galactic latitudes
towards the galactic centre and
for other regions, and is available from Vizier; images covering
for all longitudes are made available on the GLEAM Virtual Observatory (VO).server and SkyView.
We examined the latest data release from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey covering 345° < l < 60° and 180° < l < 240°, using these data and that of the Widefield Infrared Survey Explorer to follow up proposed candidate Supernova Remnant (SNR) from other sources. Of the 101 candidates proposed in the region, we are able to definitively confirm ten as SNRs, tentatively confirm two as SNRs, and reclassify five as H ii regions. A further two are detectable in our images but difficult to classify; the remaining 82 are undetectable in these data. We also investigated the 18 unclassified Multi-Array Galactic Plane Imaging Survey (MAGPIS) candidate SNRs, newly confirming three as SNRs, reclassifying two as H ii regions, and exploring the unusual spectra and morphology of two others.
