This article argues that the dovetailing economic, geopolitical, and security interests that underpin the Belt and Road Initiative demands a dispute resolution mechanism that focuses on broader interests and legal rights. Using the China-Pakistan Economic Corridor (CPEC) as a case study, it identifies the conditions in which Chinese investors could have initiated an investment arbitration but did not. This can be explained by the rights-based orientation of investment treaties failing to reflect the interests of multi-project initiatives. Instead, alternative methods of home state intervention, such as state-funded political risk insurance, are used to protect investors. In other words, the political economy of CPEC investments refuses to utilize hard law mechanisms. Given this context, mediation may be a viable alternative. These circumstances accelerate the trend towards “de-legalization”, which is often cited as an inevitable consequence of the emerging “geoeconomic order” but suggests that reasons other than national security are the cause.
It is almost 40 years since Borkovec et al. (1983) provided the definition of worry that has guided theory, research and treatment of Generalized Anxiety Disorder (GAD). This review first considers the relative paucity of research but the proliferation of models. It then considers nine models from 1994 to 2021 with the aim of understanding why so many models have been developed.
Methods and Results:
By extracting and coding the components of the models, it is possible to identify similarities and differences between them. While there are a number of unique features, the results indicate a high degree of similarity or overlap between models. The question of why we have so many models is considered in relation to the nature of GAD. Next, the treatment outcome literature is considered based on recent meta-analyses. This leads to the conclusion that while efficacy is established, the outcomes for the field as a whole leave room for improvement. While there may be scope to improve outcomes with existing treatments, it is argued that rather than continue in the same direction, an alternative is to simplify models and so simplify treatments.
Discussion:
Several approaches are considered that could lead to simplification of models resulting in simpler or single-strand treatments targeting specific processes. A requirement for these approaches is the development of brief assessments of key processes from different models. Finally, it is suggested that better outcomes at the group level may eventually be achieved by narrower treatments that target specific processes relevant to the individual.
The quantity of archaeological data for the fortified hilltop settlements of the Late Intermediate period on the Andean altiplano, called pucaras, varies greatly. Some areas, such as the territory of the Colla Aymara chieftaincy east of Lake Titicaca, are well documented thanks to recent and exhaustive research. Other areas, such as the territories of the Lupacas and the Pacajes, are much less documented. From comparative spatial analyses of satellite images from these two territories, we obtained new data on pucaras, whose characteristics seem to differ from those proposed in the archaeological literature. Through a combination of fieldwork and spatial analysis of 295 pucaras, we identified 252 unpublished sites and propose a new typology comprising four categories. Based on ethnohistoric data and the results of the architectural and geographical analyses, we discuss the possible motivations for building so many pucaras; we suggest that some reasons are of a symbolic nature.
Successful ageing continues to be a key theme in contemporary ageing discourses, where good physical and cognitive health in older age is an individualised responsibility. This paper explores how Australian aged care stakeholder discourse contributes to constructions of self-responsibility for brain health and dementia prevention in older persons. Brain health advice messages about diet, exercise and ‘brain fitness’ by aged care stakeholders are argued to construct a moral framework of ‘brainwork practices’ to prevent or delay dementia. This study performed discourse analysis of a sample of public online aged care stakeholder documents (N = 170) to reveal three key concepts in discursive constructions of dementia. The first concept characterises dementia as a disastrous force to be opposed; the second is a biomedical concept of dementia as preventable (or able to be delayed) in a ‘successful’ older age, while the third reflects neurocultural ideas that fetishise perfect memory as the best defence against cognitive decline and dementia. Identifying this matrix of responsibilising ‘brainwork practices’ messages by aged care stakeholders makes a contribution within social gerontology to revealing neoliberal conceptions of older age as an outcome of lifestyle and consumer choices, where dementia is constructed as ‘failed’ or ‘unsuccessful’ ageing.
Recently, a number of philosophers have argued that, despite appearances, the success of Don Marquis's well-known future-like-ours argument against abortion does not turn, in an important way, on the metaphysics of identity. I argue that this is false. The success of Marquis's argument turns on precisely two issues: first, whether it is prima facie seriously wrong to deprive something of a future like ours; second, whether, in a counterfactual circumstance in which an abortion does not occur, the foetus is numerically identical with something that, later on, experiences a life like ours. Since the former claim is plausible (albeit disputable), the success of Marquis's argument does turn on the metaphysics of identity in an important way. Before defending a positive argument for this position, I consider what I take to be the most promising way of challenging it. This involves a recent objection to Marquis by Tim Burkhardt (2021). Burkhardt claims that his objection floats free of the metaphysics of identity. I argue that it fails to do so, and that in fact it fails outright. I end by considering the relationship between my arguments and the question of what matters in survival.
We study the statistics of passive scalars (either temperature or concentration of a diffusing substance) at friction Reynolds number ${Re}_{\tau }=1140$, for turbulent flow within a smooth straight pipe of circular cross-section, in the range of Prandtl numbers from ${Pr}=0.00625$, to ${Pr}=16$, using direct numerical simulations (DNS) of the Navier–Stokes equations. Whereas the organization of passive scalars is similar to the axial velocity field at ${Pr} = O(1)$, similarity is impaired at low Prandtl number, at which the buffer-layer dynamics is filtered out, and at high Prandtl number, at which the passive scalar fluctuations become confined to the near-wall layer. The mean scalar profiles at ${Pr} \gtrsim 0.0125$ are found to exhibit logarithmic overlap layers, and universal parabolic distributions in the core part of the flow. Near-universality of the eddy diffusivity is exploited to derive accurate predictive formulas for the mean scalar profiles, and for the corresponding logarithmic offset function. Asymptotic scaling formulas are derived for the thickness of the conductive (diffusive) layer, for the peak scalar variance, and its production rate. The DNS data are leveraged to synthesize a modified form of the classical predictive formula of Kader & Yaglom (Intl J. Heat Mass Transfer, vol. 15, 1972, pp. 2329–2351), which is capable of accounting accurately for the dependence on both Reynolds and Prandtl numbers, for ${Pr} \gtrsim 0.25$.
This introduction begins with a brief overview of the three major factors shaping economic life and exchange in India, as laid out by contributions in the edited volume Rethinking Markets in Modern India: embedded exchange, contested jurisdiction, and pliable markets. The overarching logic of all the contributions is that markets in India must be understood as path dependent, that is, expressing a historical trajectory and specific, and changing, political and moral regimes. The remainder of this introduction discusses the origins of the distinction between ‘economy’ and ‘culture’ in the nationalist critiques of empire and how these critiques have led to a widespread moral ambivalence vis-à-vis the commercialization of everyday life in India that persists today across the political spectrum.
Spatial linear stability analysis is used to study the axisymmetric screech tones generated by twin converging round nozzles at low supersonic Mach numbers. Vortex-sheet and finite-thickness models allow for identification of the different waves supported by the flow at different conditions. Regions of the frequency–wavenumber domain for which the upstream-propagating guided jet modes are observed to be neutrally stable are observed to vary as a function of solution symmetry, jet separation, $S$, and the velocity profile used. Screech-frequency predictions performed using wavenumbers obtained from both models agree well with experimental data. Predictions obtained from the finite-thickness model better align with the screech tones measured experimentally and so are seen to be an improvement on predictions made with the vortex sheet. Additionally, results from the finite-thickness model predict both symmetric and antisymmetric screech tones for low $S$ that are found in the vortex-sheet model only at greater $S$. The present results indicate that the feedback loop generating these screech tones is similar to that observed for single-jet resonance, with equivalent upstream and downstream modes.
The aim of this study was to train and assess firefighters’ skill attainment in the use of tourniquets, and to assess their skill retention after 3 mo. The purpose is to show if firefighters can successfully apply a tourniquet after a short course based on the Norwegian national recommendation for civil prehospital tourniquet use.
Methods:
This is a prospective experimental study. The study population were firefighters, and the inclusion criterion was any on-duty firefighter. The first phase consisted of baseline precourse testing (T1), a 45-min course, followed by immediate retesting (T2). The second phase consisted of retesting of skill retention after 3 mo (T3).
Results:
A total of 109 participants at T1, 105 at T2, and 62 participants at T3. The firefighters achieved a higher proportion of successful tourniquet applications at T2 (91.4%; 96 of 105) as well as T3 (87.1%; 54 of 62) compared with 50.5% at T1 (55 of 109) (P = 0.009). Mean application time was 59.6 s (55.1-64.2) in T1, 34.9 s (33.3-36.6) in T2 and 37.7 s (33.9-41.4) in T3.
Conclusion:
A sample of firefighters can successfully apply a tourniquet after a 45-min course based on the 2019 Norwegian recommendation for civil prehospital tourniquet use. Skill retention after 3 mo was satisfactory for both successful application and application time.
Far from being a monolithic approach to psychotherapy, cognitive behavioural therapy (CBT) is in fact an umbrella term to describe a family of psychological therapies that share many common features but also have nuanced differences. Of the CBTs, two are often conflated under the ‘CBT’ moniker, namely cognitive therapy (CT) and rational emotive behaviour therapy (REBT). In this article, we explore some of the key differences and similarities between CT and REBT, touching on philosophy, practical implementation, and literature. We provide a brief hypothetical case study to demonstrate the different ways a therapist using CT and REBT might tackle the same client problem. We do not declare either approach superior, but suggest each might have their advantages in certain contexts and acknowledge that skilful practitioners could, and often do, integrate both approaches. As CBT continues to evolve and move into new areas, it is important that psychology practitioners and researchers are clear about which specific approach to CBT they are delivering, measuring and/or reporting on.
I began working on this article in the winter of 2022, when Russia's invasion of Ukraine shattered the fragile stability of Europe. Artur Solomonov's tragifarce How We Buried Josef Stalin (2019) speaks directly to this catastrophic time but also to the legacy of Stalinism in Russia. ‘A play about flexibility and immortality’, Solomonov's farce confronts its audience with the dilemma of Stalinism, which Putin's putrid regime continues to mobilize. Using irony, hyperbole and grotesque, it proposes a dramaturgical response to the question of why hostility to the world, isolationism and nationalistic aspirations are deeply ingrained in the collective psyche of Russian society. To Solomonov, the issue rests in the malleability of a Russian psyche that embraces an image of the tyrant and allows it to remain immortal; it also feeds Russian collective nostalgia, which prepared the ground for the rise of what Lev Gudkov called ‘recurring totalitarianism’.
North Dakota (ND) had the highest coronavirus disease 2019 (COVID-19) case and mortality rate in the United States for nearly 2 mo. This study aims to compare 3 metrics ND used to guide public health action across its 53 counties.
Methods:
Daily COVID-19 case and death totals in North Dakota were evaluated using data from the COVID-tracker website provided by the North Department of Health (NDDoH). It was reported as: active cases per 10,000, tests administered per 10,000, and test positivity rate (the North Dakota health metric). The COVID-19 Response press conferences provided data for the Governor’s metric. The Harvard model used daily new cases per 100,000. A chi-squared test was used to compare differences in these 3 metrics on July 1, August 26, September 23, and November 13, 2020.
Results:
On July 1, no significant difference between the metrics was found. By September 23, Harvard’s health metric indicated critical risk while ND’s health metric was moderate risk, and the Governor’s metric was still low risk.
Conclusions:
ND’s and the Governor’s metric underrepresented the risk of the COVID-19 outbreak in North Dakota. The Harvard metric reflected North Dakota’s increasing risk; it should be considered as a national standard in future pandemics.
Public Health Implications:
Model-based predictors could guide policy-makers to effectively control spread of infectious disease; proactive models could reduce risk of disease as it progresses in vulnerable communities.
