Among the different approaches in mental health activism, there is an ongoing concern with the concepts and meanings that should be brought to bear upon mental health phenomena. Aspects of Mad Pride activism resist the medicalisation of madness, and seek to introduce new, non-pathologizing narratives of psychological, emotional, and experiential states. This essay proposes a view of Mad Pride activism as engaged in no less than the creation of a new culture of madness. The revisioning and revaluing of madness requires transformations in the basic concepts constitutive of current mental health narratives. This process is illustrated with the concept of self and its relation to passivity phenomena (thought insertion). The essay concludes with some of the challenges facing Mad Pride's ambition to enrich the cultural repertoire.
As law graduates wield significant influence in public life, law schools’ responsibility for cultivating students’ civic capacities and dispositions remains an important but often neglected project. Taking up this project, this article traces a thread of deliberative democratic aspirations within legal education scholarship and explores the potential of participation within law schools’ own political processes for realising these ideals. To do so, it examines law students’ experiences of an experiment with deliberative democracy’s leading institutional innovation – the deliberative mini-public – and demonstrates the ways in which participation fostered deliberative capacities, a more collective orientation, and increased confidence. Ultimately, the article illustrates the mutually reinforcing nature of civic and legal education, affirms law schools’ broader role within society and offers both theoretical and practical insights into the place of democratic innovation within the law school.
We investigate when a Legendrian knot in the standard contact ${{\mathbb{R}}}^3$ has a non-orientable exact Lagrangian filling. We prove analogs of several results in the orientable setting, develop new combinatorial obstructions to fillability, and determine when several families of knots have such fillings. In particular, we completely determine when an alternating knot (and more generally a plus-adequate knot) is decomposably non-orientably fillable and classify the fillability of most torus and 3-strand pretzel knots. We also describe rigidity phenomena of decomposable non-orientable fillings, including finiteness of the possible normal Euler numbers of fillings and the minimisation of crosscap numbers of fillings, obtaining results which contrast in interesting ways with the smooth setting.
We investigate drop break-up morphology, occurrence, time and size distribution, through large ensembles of high-fidelity direct-numerical simulations of drops in homogeneous isotropic turbulence, spanning a wide range of parameters in terms of the Weber number $We$, viscosity ratio between the drop and the carrier flow $\mu _r=\mu _d/\mu _l$, where d is the drop diameter, and Reynolds ($Re$) number. For $\mu _r \leq 20$, we find a nearly constant critical $We$, while it increases with $\mu _r$ (and $Re$) when $\mu _r > 20$, and the transition can be described in terms of a drop Reynolds number. The break-up time is delayed when $\mu _r$ increases and is a function of distance to criticality. The first break-up child-size distributions for $\mu _r \leq 20$ transition from M to U shape when the distance to criticality is increased. At high $\mu _r$, the shape of the distribution is modified. The first break-up child-size distribution gives only limited information on the fragmentation dynamics, as the subsequent break-up sequence is controlled by the drop geometry and viscosity. At high $We$, a $d^{-3/2}$ size distribution is observed for $\mu _r \leq 20$, which can be explained by capillary-driven processes, while for $\mu _r > 20$, almost all drops formed by the fragmentation process are at the smallest scale, controlled by the diameter of the very extended filament, which exhibits a snake-like shape prior to break-up.
The present paper provides an overview of the approach to developing food-based dietary recommendations in the UK. UK dietary recommendations are based on independent advice from the Scientific Advisory Committee on Nutrition (SACN). SACN's remit includes specific reference to the nutrient content of individual foods and advice on diet as a whole, including the definition of a balanced diet. SACN's approach is set out in its Framework for Evaluating Evidence and its assessments are supported by the data provided by the National Diet and Nutrition Survey. SACN's risk assessments have primarily focused on energy requirements, macro and micronutrients and/or the needs of specific population groups. However, dietary patterns or individual foods and health outcomes have been considered where sufficient evidence is available. An example of this is SACN's risk assessment on carbohydrates and health, which included consideration of evidence on sugar-sweetened beverages and the resulting dietary recommendations on free sugars and sugar-sweetened beverages led to a range of policies to reduce sugar intake in the UK, including the soft drinks industry levy. SACN has also recently published a position statement on processed foods and health. Government dietary advice is encapsulated in the UK's national food model, the Eatwell Guide. The Eatwell Guide shows the proportions in which different food groups should be consumed to have a well-balanced, healthier, more sustainable diet, to help meet nutrient requirements and reduce the risk of chronic disease. Any substantive change to government dietary advice is likely to lead to a review of the national food model.
Guided by a novel analytic framework, this study investigates the developmental mechanism through which parental warmth is related to young adult depression. Data were from a large sample of participants followed from early adolescence to young adulthood (N = 1,988; 54% female). Using structural equation modeling, we estimated and compared competing developmental models – enduring effects vs. revisionist models – to assess whether parental warmth during adolescence had enduring or transient effects on depression in young adulthood. We also examined whether contemporaneous experiences of parental warmth in young adulthood were more salient than parental warmth in adolescence. Results supported the revisionist model: early intergenerational experiences in adolescence predicted psychopathology early in young adulthood, but their unique effects gradually diminished; whereas parental warmth in young adulthood continued to be protective of young adult depression. Effects of mother and father warmth on young adult depression were similar in pattern and magnitude. Results were held when accounting for covariates such as adolescent sex, family income status, and family structure. Young adult mental health interventions may consider targeting maintenance or improvement in parental warmth to help offset the long-term impact of adversity early in life.
In the wake of the COVID-19 pandemic, the United States is actively reshaping parts of its national security enterprise. This article explores the underlying politics, with a specific interest in the context of biosecurity, biodefense, and bioterrorism strategy, programs, and response, as the United States responds to the most significant outbreak of an emerging infectious disease in over a century. How the implicit or tacit failure to recognize the political will and political decision-making connected to warfare and conflict for biological weapons programs in these trends is explored. Securitization of public health has been a focus of the literature over the past half century. This recent trend may represent something of an inverse: an attempt to treat national security interests as public health problems. A hypothesis is that the most significant underrecognized problem associated with COVID-19 is disinformation and the weakening of confidence in institutions, including governments, and how adversaries may exploit that blind spot.
Let $({\cal{A}},{\cal{E}})$ be an exact category. We establish basic results that allow one to identify sub(bi)functors of ${\operatorname{Ext}}_{\cal{E}}(-,-)$ using additivity of numerical functions and restriction to subcategories. We also study a small number of these new functors over commutative local rings in detail and find a range of applications from detecting regularity to understanding Ulrich modules.
The vortex dynamics and the structural load in a step cylinder (consisting of a small, d, and a large, D, cylinder) flow are investigated numerically at Reynolds number ($Re_D$) 150 for diameter ratios $D/d=2.0, 2.4$ and 2.8. First, the formation mechanism of a non-uniform oblique vortex shedding (the vortex shedding frequency remains unchanged as the oblique shedding angle varies) behind the small cylinder is explained: an increase in the production rate of the vortex strength and a farther downstream movement of the vortex formation position occur simultaneously as the vicinity of the step is approached along the small cylinder. Second, the structural load (the drag and lift) along the step cylinder is investigated, where four local extremes (two local minima and two local maxima) are observed. An in-depth investigation of the vortex dislocation effects on the structural load is provided, showing that the decreased circulation in the near wake and the weakened staggered Kármán vortex shedding pattern cause a major reduction (90 %) of the sectional lift amplitude and a relatively modest reduction (5.7 %) of the sectional drag amplitude, compared with the corresponding sectional force when no vortex dislocation occurs. This new knowledge combined with the three-dimensional effect of the step cylinder wake (caused by the blending of the small and larger cylinder wakes around the step) explain the formation of the four local extremes and the distribution of the structural load between them. Finally, it is found that the increasing $D/d$ amplifies the structural load variation along the step cylinder.
Research on policy experimentation has mainly focused on central–local relations; scholars have paid little attention to the interaction between policy experimentation and the public. We argue that policy experimentation can be used by decision makers as an instrument to communicate with the public, facilitating the building of a social consensus regarding controversial policies. We evaluate the effects of the Chinese government's policy experimentation efforts to promote shared responsibility between the state and individuals for the urban pension system on the public's regime support. Evidence from two rounds of a nationwide survey conducted before and after the policy experiment indicates that the policy experimentation has significantly contributed to citizens’ acceptance of their individual welfare responsibility. Moreover, the image-building of governmental responsibility via official news, with varied intensity across regions, consolidates the political trust of residents while posing a challenge to local government credibility in the long run.
This article posits a theory of iterative stress that separates each facet of the stress map into its constituent parts, or ‘atoms’. Through the well-defined notion of complexity provided by Formal Language Theory, it is shown that this division of the stress map results in a more restrictive characterisation of iterative stress than a single-function analysis does. While the single-function approach masks the complexity of the atomic properties present in the pattern, the compositional analysis makes it explicitly clear. It also demonstrates the degree to which, despite what appear to be significant surface differences in the patterns, the calculation of the stress function is largely the same, even between quantity-sensitive and quantity-insensitive patterns. These stress compositions are limited to one output-local function to iterate stress, and a small number of what I call edge-oriented functions to provide ‘cleanup’ when the iteration function alone fails to capture the pattern.
In May 2023, the Italian region Emilia-Romagna was hit by intense rainfall, which caused extensive floods in densely populated areas. On May 4, 2023, a 12-month state of emergency was declared in the region with the activation of response and recovery plans. This field report provides an overview of the health response to the floods, paying particular attention to the measures put in place to ensure care for displaced populations and raising interesting points of discussion regarding the role of the health system during extreme weather events (EWEs). The considerations that emerge from this report underline the need for a primary care approach to disasters, especially when these occur in areas with a high prevalence of elderly resident population, and underscore the importance of integration of different levels of care.
An accurate dynamic model of a robot is fundamentally important for a control system, while uncertainties residing in the model are inevitable in a physical robot system. The uncertainties can be categorized as internal disturbances and external disturbances in general. The former may include dynamic model errors and joint frictions, while the latter may include external payloads or human-exerted force to the robot. Disturbance observer is an important technique to estimate and compensate for the uncertainties of the dynamic model. Different types of disturbance observers have been developed to estimate the lumped uncertainties so far. In this paper, we conducted a brief survey on five typical types of observers from a perspective of practical implementation in a robot control system, including generalized momentum observer (GMO), joint velocity observer (JVOB), nonlinear disturbance observer (NDOB), disturbance Kalman filter (DKF), and extended state observer (ESO). First, we introduced the basics of each observer including equations and derivations. Two common types of disturbances are considered as two scenarios, that is, constant external disturbance and time-varying external disturbance. Then, the observers are separately implemented in each of the two simulated scenarios, and the disturbance tracking performance of each observer is presented while their performance in the same scenario has also been compared in the same figure. Finally, the main features and possible behaviors of each type of observer are summarized and discussed. This survey is devoted to helping readers learn the basic expressions of five typical observers and implement them in a robot control system.
We prove that for every tree $T$ of radius $h$, there is an integer $c$ such that every $T$-minor-free graph is contained in $H\boxtimes K_c$ for some graph $H$ with pathwidth at most $2h-1$. This is a qualitative strengthening of the Excluded Tree Minor Theorem of Robertson and Seymour (GM I). We show that radius is the right parameter to consider in this setting, and $2h-1$ is the best possible bound.
The potential of Momordica charantia var. muricata, a little-known wild form, as a source of favourable alleles in breeding and improvement of bitter melons (M. charantia var. charantia), is demonstrated. The M. charantia var. charantia cultivar Priyanka and M. charantia var. muricata accession IC634896 were crossed with each other and cross ability and performance of F1 plants were studied. These botanical varieties were fully cross-compatible on either direction. Surprisingly, cross of Priyanka × IC634896 produced 80.0 fruits compared to 17.0 in Priyanka and fruit yield per plant (2287.4 g) was more than double that in Priyanka (1042.3 g). This hybrid has to be back crossed with commercial cultivar to improve its fruit size, with no compromise on fruit number. This is the first study showing the promise of M. charantia var. muricata as a potential donor in bitter melon breeding.
