Cette étude a sondé 46 médecins de famille québécois quant à leurs pratiques pour l’évaluation et le dépistage des conducteurs à risque afin 1) de mieux comprendre leur niveau de compétence perçu; 2) de recenser les difficultés rencontrées dans le processus de prise de décision et 3) de documenter leurs besoins et attitudes quant à une collaboration plus étroite avec les ergothérapeutes. Les participants (femmes : 84,8 %; moyenne d’expérience : 15,7 (±12,1) ans) ont répondu à un sondage en ligne de 30 questions. Les résultats de cette étude démontrent que malgré un certain confort à effectuer l’évaluation et le dépistage des conducteurs à risque, les médecins ne se considèrent pas comme les professionnels les mieux qualifiés pour ce faire. Ils reconnaissent également le rôle que jouent les ergothérapeutes dans le dépistage de cette clientèle et l’intervention auprès d’elle. Ils voient ainsi la pertinence d’avoir accès aux services de ces professionnels en soins de première ligne.
Katok [Lyapunov exponents, entropy and periodic points of diffeomorphisms. Publ. Math. Inst. Hautes Études Sci.51 (1980), 137–173] conjectured that every $C^{2}$ diffeomorphism f on a Riemannian manifold has the intermediate entropy property, that is, for any constant $c \in [0, h_{\mathrm {top}}(f))$, there exists an ergodic measure $\mu $ of f satisfying $h_{\mu }(f)=c$. In this paper, we obtain a conditional intermediate metric entropy property and two conditional intermediate Birkhoff average properties for basic sets of flows that characterize the refined roles of ergodic measures in the invariant ones. In this process, we establish a ‘multi-horseshoe’ entropy-dense property and use it to get the goal combined with conditional variational principles. We also obtain the same result for singular hyperbolic attractors.
From the 1940s to the 1970s, British governments steered manufacturing businesses to peripheral regions designated as needing more employment. This approach was delivered through a Regional Policy that deployed industrial location controls and financial incentives. Effectiveness varied over time but was dramatic in the mid-1940s, when it boosted the regional stock of secondary manufacturing to the extent that its legacy remains visible today. The literature describes how this Regional Policy was a peacetime policy, albeit one formulated during the war. This article, however, proposes that the most successful phase of Regional Policy was an extension of wartime policies governing regional manufacturing businesses producing munitions. It uses a case study of Wales to make two arguments. One is that the Regional Policy associated with the postwar period began to be implemented before the war had ended. The other is that the Board of Trade pursued the policy through repurposed wartime governance mechanisms within an economy that remained subject to onerous state controls. The case outlines a short but consequential burst of assertive state involvement that shaped business activity throughout much of regional Britain, echoing Philip Scranton and Patrick Fridenson’s arguments concerning “the state always being in” given its role in shaping markets, business behavior, and regulations.
The sinusoidal roughness effect is investigated using a direct numerical simulation (DNS) of a spatially developing turbulent boundary layer (TBL) over three-dimensional sinusoidal roughness. The validity of Townsend's outer-layer similarity hypothesis is assessed based on comparisons of mean and second-order flow statistics, with a DNS of smooth-wall TBL data set at a similar Reynolds number. The total, Reynolds and dispersive stress tensors are calculated using the double-averaging procedure. The mean and second-order statistical similarities in the outer layer between rough-wall and smooth-wall TBLs are generally observed. The transport between total, turbulent and dispersive kinetic energy is investigated utilising triple-decomposed kinetic energy transports equations. The transport behaviour of turbulent kinetic energy (TKE) is significantly affected by the local mean shear induced by the surface roughness. However, the TKE transport shows good collapse with the smooth-wall case in the outer region of the flow. On the other hand, the transport of dispersive kinetic energy, including local production, redistribution and dissipation, are confined within the roughness sublayer. The intercomponent transfer between TKE and dispersive kinetic energy is quantified from the triple-decomposed kinetic energy transport equations. The intercomponent energy transfer is associated with the local spatial gradients of the turbulent momentum fluxes generated near the roughness canopy.
The dichotomies of ‘typical/atypical’ or ‘first/second generation’ have been employed for several decades to classify antipsychotics, but justification for their use is not clear. In the current analysis we argue that this classification is flawed from both clinical and pharmacological perspectives. We then consider what approach should ideally be employed in both clinical and research settings.
Reductions in the cost of transporting manufactured goods have been an important element in economic development in the recent past, and previous research suggests that the Roman period in Britain also saw substantial reductions in such costs. The authors investigate how far it is possible to measure changes in transport costs by considering the spatial distributions of pottery from known Roman production locations over time. Their analysis of an extensive database of pottery assemblages is designed to evaluate a series of expectations concerning how reductions in transport costs may have affected such assemblages and their distribution. Results suggest that costs were reduced by a factor of about two, leading to related changes in pottery production, distribution, and consumption over time. The ability to quantify changes in transport costs opens new perspectives for investigating the general determinants of economic development using archaeological data.
To draw concrete pictures of the hierarchy of multiscale coherent vortices in turbulence behind a cylinder and to reveal their sustaining mechanism, we conduct direct numerical simulations of the turbulence at the Reynolds number, which is defined by the uniform inflow velocity and the cylinder diameter, $5000$. The turbulence consists of three kinds of hierarchies of coherent vortices in three distinct regions: namely, the downstream region, the recirculation region just behind the cylinder and the separate shear layers. By tracking the temporal evolution of multiscale vortices in each of these regions, we demonstrate that, in all the three regions, smaller coherent vortices tend to align in the direction perpendicular to larger ones. This implies that smaller vortices are stretched and amplified in the strain-rate fields around larger ones. We also show the relevance of this observation to the energy cascade. Smaller-scale vortices receive the kinetic energy in the regions where they are stretched by larger-scale vortices; and, at the same time, they tend to compress larger ones, thus reducing larger-scale kinetic energy.
Does dual citizenship acceptance increase immigrants’ propensity to naturalize and, if so, for whom does this matter most? We exploit exogenous variation in citizenship legislation in 200 migrant-origin countries to identify the effect of destination country policy reform. We hypothesize that the value of the origin country citizenship moderates the reform effect. We test our identification strategy in two West European countries with contrasting reforms: a canonical liberal reform in Sweden (2001) and an atypical restrictive reversal in the Netherlands (1997). We apply a staggered difference-in-differences model employing administrative data on complete migrant populations. We find reform effects remarkably similar in effect size and heterogeneity, with liberalizing reform increasing naturalization rates by 6.7 percentage points and restrictive change decreasing rates by 6.4 percentage points. The effect is concentrated among immigrants from EU and highly developed countries. Our quasi-experimental evidence informs naturalization scholarship and public debate on migrant political integration.
The language-guided visual robotic grasping task focuses on enabling robots to grasp objects based on human language instructions. However, real-world human-robot collaboration tasks often involve situations with ambiguous language instructions and complex scenarios. These challenges arise in the understanding of linguistic queries, discrimination of key concepts in visual and language information, and generation of executable grasping configurations for the robot’s end-effector. To overcome these challenges, we propose a novel multi-modal transformer-based framework in this study, which assists robots in localizing spatial interactions of objects using text queries and visual sensing. This framework facilitates object grasping in accordance with human instructions. Our developed framework consists of two main components. First, a visual-linguistic transformer encoder is employed to model multi-modal interactions for objects referred to in the text. Second, the framework performs joint spatial localization and grasping. Extensive ablation studies have been conducted on multiple datasets to evaluate the advantages of each component in our model. Additionally, physical experiments have been performed with natural language-driven human-robot interactions on a physical robot to validate the practicality of our approach.
Menopause is a natural developmental phase that all women go through from their early forties to mid-fifties, marking the transition from the reproductive to the non-reproductive years. This is characterised as the permanent cessation of menses due to progressive ovarian failure. Each woman's experience of the menopause is unique. Biopsychosocial changes occur during this time with some symptoms affecting up to 80 % of women and lasting for 4–5 years from the peri- to post-menopause. Reduced oestrogen may predispose some women to health issues following menopause, such as heart disease, diabetes, stroke and cognitive decline. It is vital to understand how to promote health and well-being to reduce the risk of developing chronic conditions in later life. Increased symptoms and concerns about health during the menopausal transition can be cues to action for some women to actively maintain their health. Menopause represents a window of opportunity to promote health, and to support women to make healthier lifestyle choices, part of the National Institute for Clinical Excellence guidelines for menopause management. Identifying appropriate strategies to change behaviour is less clear. Theories of behaviour change can provide frameworks to gain more insight into the facilitators and barriers to behaviour and can inform the researcher on what needs to change. This information can be used to inform the design, content, implementation and evaluation of a lifestyle intervention. This review paper will explore the impact of menopause on health and well-being generally, and the benefits of designing more effective theory-driven behaviour change interventions for menopause.
An online pattern recognition method of lower limb movements is proposed based on the personalized surface electromyography (sEMG) signals, and the corresponding experimental researches are performed in the rehabilitation training. Further, a wireless wearable acquisition instrument is used. Based on this instrument, a host computer for the personal online recognition and real-time control of rehabilitation training is developed. Three time-domain features and two features in the nonlinear dynamics are selected as the joint set of the characteristic values for the sEMG signals. Then a particle swarm optimization (PSO) algorithm is used to optimize the feature channels, and a k-nearest neighbor (KNN) algorithm and the extreme learning machine (ELM) algorithm are combined to classify and recognize individual sample data. Based on the multi-pose lower limb rehabilitation robot, the real-time motion recognition and the corresponding rehabilitation training are carried out by using the online personalized classifier. The experimental results of eight subjects indicate that it takes only 6 min to build an online personalized classifier for the four types of the lower limb movements. The recognition between switches of different rehabilitation training movements is timely and accurate, with an average recognition accuracy of more than 95%. These results demonstrate that this system has a strong practicability.
The aim of the paper is to review the current evidence on the impact of ‘the timing of energy intake’ on the risk of developing obesity and obesity-related metabolic diseases. The prevalence of obesity is currently increasing worldwide thus becoming a severe health burden for most countries. Indeed, obesity represents a risk factor for several non-communicable diseases such as cancer, type 2 diabetes, dyslipidaemia, CVD and overall mortality. In order to treat obesity, several pharmacological approaches have been developed and are indicated for subjects with obesity with a BMI ≥ 30 kg/m2 or ≥ 27 kg/m2 and obesity-related comorbidities. For severe obesity (BMI ≥ 40 kg/m2), bariatric surgery represents a promising approach. The most common bariatric surgical procedures are represented by the Roux-en-Y gastric bypass, laparoscopic adjustable band, laparoscopic gastric sleeve and biliopancreatic diversion with duodenal switch. Both anti-obesity pharmacological and surgical treatments require change in lifestyle. When a nutritional plan is established, attention is usually paid to macronutrient composition and energy intake, while ‘the time of food’ is not taken into account. Chronotype, which is the attitude of a subject to carry out most of their daily activities in the first (morning chronotype) or second half (evening chronotype) of the day, has been reported to have a role in the pathogenesis of obesity and obesity-related cardiometabolic diseases as well as eating speed. Thus, adopting a physiological timing of energy intake could be an additional strategy to potentiate the current anti-obesity approaches.
According to the phenomenon commonly known as action effect and vastly replicated across the judgment and decision-making literature, more regret is associated with decisions resulting from action than inaction. Action vs. inaction, however, might either refer to change vs. no change or doing something vs. not doing something. The purpose of this study was to examine the effect of this variation in operationalization of action-inaction on the strength of action effect, for both positive and negative outcomes, across four different domains of employment, finance, education, and health. This was an experimental scenario-based study (N = 215) with four between-subjects conditions varying in outcome valence and the actor’s initial state as either engaged or non-engaged in a particular course of action. Action effect was found to be stronger with respect to the initially engaged than the initially non-engaged decision-maker (ηp2 = .04), indicating that action as change results in a stronger action effect than action as doing something. The effect of the initial state was also moderated by domain. In addition, we both replicated and went beyond prior empirical literature regarding the effect of outcome valence and domain on action effect, with our findings being mostly consistent across joy and regret. Findings are discussed in light of the norm theory and its key concept of normality and contribute to the literature on moderators of action effect.
This article surveys plans that envisioned new leisure uses for derelict landscapes in Britain from about 1966 to 1979. These plans were an attempt to transform areas of Britain in ways that cut across issues ranging from deindustrialization to planning, landscape, environmentalism, industrial heritage, and leisure. The author argues for the importance of the profession of landscape architects in setting the agenda for tackling industrial dereliction. It then shows these issues playing out in three locations: in the Lea Valley, in Stoke-on-Trent, and in Telford New Town. Derelict landscapes were a visual manifestation of the various crises that continue to structure historians’ accounts of the 1970s, but the author shows how the response to the issue was characterized by an almost utopian optimism that these problems could be resolved in a way that would stimulate new forms of living.
This paper is interested in the role and function of memories in United Nations Security Council debates about humanitarian intervention. It posits that historical experiences and their lessons serve as interpretative devices for the abstract international norms and principles under discussion. The paper speaks of ‘international memories’ where the meaning and lessons derived from the past coalesce among a group of states. Empirically, its case study explores how the memories of totalitarianism/fascism and colonialism were employed in United Nations (UN) representatives’ verbal pleas to intervene in Libya and Syria after the Arab Spring. It finds that those who supported or opposed humanitarian intervention held different interpretations of these memories and their lessons. In each case, however, memories provided essential normative guidance to states when it came to implementing the abstract international principles, norms, and rights that underlie humanitarian intervention.
