This book “follows the decisions” and studies how in different countries amendment rules have a fundamental impact on how easy it will be to make amendments and how frequent and/or significant these amendments are likely to be. The amendment rules specify how many institutions are required to approve the change, what the conditions are (quorums, qualified majorities) in each one, and whether these rules operate in a conjunctive or disjunctive way. All these conditions have specific effects on the constitutional rigidity of a country, which in turn is expected to have effects in three different directions. First, the frequency and significance of amendments are inversely related with the constitutional rigidity of the country and its variance. The more significant the amendments, the stronger this relationship. Second, the length of the constitution is correlated with a series of negative results like time inconsistency as well as economic variables. Third, constitutional rigidity affects judicial independence of the supreme or constitutional court and its variance. The main contribution of this book is the combination of these ideas in a coherent framework, from theory to case studies or application to all democracies.
Oscillatory flows induced by a monochromatic forcing frequency $\omega$ close to a planar surface are present in many applications involving fluid–matter interaction such as ultrasound, vibrational spectra by microscopic pulsating cantilevers, nanoparticle oscillatory magnetometry, quartz crystal microbalance and more. Numerical solution of these flows using standard time-stepping solvers in finite domains present important drawbacks. First, hydrodynamic finite-size effects scale as $1/L_{\parallel }^2$ close to the surface and extend several times the penetration length $\delta \sim \omega ^{-1/2}$ in the normal $z$ direction and second, they demand rather long transient times $O(L_z^2)$ to allow vorticity to diffuse over the computational domain. We present a new frequency-based scheme for doubly periodic (DP) domains in free or confined spaces which uses spectral-accurate solvers based on fast Fourier transform in the periodic $(xy)$ plane and Chebyshev polynomials in the aperiodic $z$ direction. Following the ideas developed for the steady Stokes solver (Hashemi et al. J. Chem. Phys. vol. 158, 2023, p. 154101), the computational system is decomposed into an ‘inner’ domain (where forces are imposed) and an outer domain (where the flow is solved analytically using plane-wave expansions). Matching conditions leads to a solvable boundary value problem. Solving the equations in the frequency domain using complex phasor fields avoids time-stepping and permits a strong reduction in computational time. The spectral scheme is validated against analytical results for mutual and self-mobility tensors, including the in-plane Fourier transform of the Green function. Hydrodynamic couplings are investigated as a function of the periodic lattice length. Applications are finally discussed.
Cinq générations doivent actuellement cohabiter sur le marché du travail, ce qui peut entraîner plusieurs bénéfices, mais également un risque de tensions et de conflits susceptibles de nuire à la collaboration des équipes de travail et à la santé des personnes vieillissantes. La coopération intergénérationnelle au travail (CIT) a été relevée dans la littérature comme une avenue intéressante pour diminuer le risque de conflits intergénérationnels, mais elle demeure peu concrètement définie. Cette étude vise à proposer une définition opérationnelle du concept de coopération intergénérationnelle au travail à l’aide de la méthode d’analyse de Walker and Avant (2019). Quarante-huit manuscrits ont été répertoriés, permettant d’identifier huit attributs caractérisant la CIT, sept antécédents et six conséquents du concept. Cette étude fait ressortir le rôle des différents acteurs dans la CIT, met en lumière les bénéfices de la CIT et permet de considérer son rôle en prévention des lésions professionnelles.
Potassium is an essential macronutrient required for plant growth and development. Over the recent decade, an important signalling role of K+ has emerged. Here, we discuss some aspects of such signalling at the various levels of plant functional organisation. The topic covered include: (1) mechanisms of long-distant K+ transport in the xylem and phloem and the molecular identity and regulation of K+ loading and unloading into plant vasculature; (2) essentiality and physiological roles of K+ cycling between shoots and roots; (3) plant sensing and signalling of low K+; (4) maintenance of K+ homeostasis at the cellular level; (5) stress-induced modulation of cytosolic K+ as a signal in plant adaptive responses to hostile environment; (6) stress-specific K+ “signatures” and mechanisms of their decoding by regulation of purine metabolism and H+-ATPase activity; (7) cytosolic K+ loss as a metabolic switch and a regulator of autophagy; and (8) vacuolar K+ transport and sensing.
Recent experiments aiming to measure phenomena predicted by strong-field quantum electrodynamics (SFQED) have done so by colliding relativistic electron beams and high-power lasers. In such experiments, measurements of collision parameters are not always feasible. However, precise knowledge of these parameters is required to accurately test SFQED.
Here, we present a novel Bayesian inference procedure that infers collision parameters that could not be measured on-shot. This procedure is applicable to all-optical non-linear Compton scattering experiments investigating radiation reaction. The framework allows multiple diagnostics to be combined self-consistently and facilitates the inclusion of known information pertaining to the collision parameters. Using this Bayesian analysis, the relative validity of the classical, quantum-continuous and quantum-stochastic models of radiation reaction was compared for several test cases, which demonstrates the accuracy and model selection capability of the framework and highlight its robustness if the experimental values of fixed parameters differ from their values in the models.
Women legislators face a variety of gendered barriers both outside and inside the legislature. Yet, little previous scholarship has quantitatively examined whether legislative insiders are biased against women and their accomplishments. We explore a new potential explanation for gender inequity in legislatures: that women in office may get less credit than men for similar achievements. If legislative insiders systematically undervalue women’s work, women will have a harder time gaining influence within the chamber; alternatively, those working in and with the legislature may be uniquely aware of the effort that goes into representational activities and can observe the work that women perform firsthand. To examine this question, we combine elite evaluations of legislators from the North Carolina General Assembly with data on committee assignments, legislative effectiveness, electoral performance, and more. We find little systematic evidence that women legislators’ accomplishments are valued less than those of the men with whom they serve.
This paper focuses on the discursive connection between the notion of autonomy and the ageing-in-place policy approach, in a context of population aging and budgetary restraint. We argue that these central elements of the policy discourse on ageing represent a governance strategy that defines ageing in place as the prevailing standard for ageing well. Through an analysis of ageing policy documents released by the Québécois government between 2012 and 2023, this paper shows a disconnect between national policy frameworks and the reality of ageing in place. The issue of ageing in place is strongly bound up with the idea of autonomy, which is mainly expressed in terms of responsibility and freedom of choice, while its implementation overlooks the social structural determinants of individual autonomy and their impact on older people’s opportunities and processes of ageing in place.
A stochastic wavevector approach is formulated to accurately represent compressible turbulence subject to rapid deformations. This approach is inspired by the incompressible particle representation model of Kassinos & Reynolds (1994), and preserves the exact nature of compressible rapid distortion theory (RDT). The adoption of a stochastic – rather than Fourier – perspective simplifies the transformation of statistics to physical space and serves as a starting point for the development of practical turbulence models. We assume small density fluctuations and isentropic flow to obtain a transport equation for the pressure fluctuation. This results in four fewer transport equations compared with the compressible RDT model of Yu & Girimaji (Phys. Fluids, vol. 19, 2007, 041702). The final formulation is closed in spectral space and only requires numerical approximation for the transformation integrals. The use of Monte Carlo for unit wavevector integration motivates the representation of the moments as stochastic variables. Consistency between the Fourier and stochastic representation is demonstrated by showing equivalency between the evolution equations for the velocity spectrum tensor in both representations. Sample clustering with respect to orientation allows for different techniques to be used for the wavevector magnitude integration. The performance of the stochastic model is evaluated for axially compressed turbulence, serving as a simplified model for shock–turbulence interaction, and is compared with linear interaction approximations and direct numerical simulation (DNS). Pure and compressed sheared turbulence at different distortion Mach numbers are also computed and compared with RDT/DNS data. Finally, two additional deformations are applied and compared with solenoidal and pressure-released limits to demonstrate the modelling capability for generic rapid deformations.
Notre société segmentée par l’âge offre peu de possibilités d’interactions intergénérationnelles authentiques. Cela contribue aux stéréotypes et préjugés envers les personnes de tous âges, particulièrement les adultes aînés. Pour favoriser une société plus inclusive et lutter contre l’âgisme, un changement de paradigme sociétal devient nécessaire. À partir d’une recherche basée sur la conception et l’apprentissage intergénérationnel, nous avons cherché à mieux caractériser ces apprentissages afin de développer des formations spécifiques pour les appuyer. Basé sur un questionnaire préliminaire (n=79), nous avons conçu un atelier pilote (français/anglais) avec huit adultes aînées et huit jeunes adultes au cours duquel les participants ont dû réaliser en binôme une vidéo sur TikTok. Nos résultats indiquent que l’apprentissage intergénérationnel doit se fonder sur une pédagogie active, les activités et les objectifs pédagogiques doivent être multiples pour être réalisées en binômes intergénérationnels, le format doit permettre de développer une relation de confiance et l’évaluation doit être personnelle.
This chapter uses examples from different countries (Israel, Czech Republic, United States, Poland, South Korea, Benin, Greece, Belgium, Luxembourg, Nigeria, Guyana, Colombia, France, Switzerland, Spain, Italy, Guatemala, Moldova, Denmark, Australia, Ireland, India, Hungary, Slovakia), as well as US states (Michigan, Ohio, North Dakota, Arkansas, Nevada) to demonstrate the variety of amendment procedures which range from a simple majority to approval by multiple actors, by qualified majorities, by one or more referendums, or by multiple votes (sometimes with intervening elections). In addition, sometimes these rules may be combined or considered as alternatives. These procedures are not only extremely diverse but are also very significant as demonstrated by the fact that they become the object of political conflict among the relevant actors or are even modified by some of the actors in order to achieve their political goals.
Discussions about economic equality have, in recent years, extended beyond considerations of income distribution to encompass the distribution of wealth and its intergenerational transfer. Driven by new and more frequent data, a better understanding is emerging of the concentration of wealth within society and the dynamics of its transfer between generations.
This article contributes to that discussion by assessing the economic and social rationales for the taxation of intergenerational wealth transfers. It outlines the social policy case for inheritances taxes grounded in vertical equity principles. Then it presents comparative data on household wealth across high-income European countries before focusing on one of these, Ireland, to consider whether current inheritance taxation policies counter or perpetuate these inequalities. Focusing on that system, the article explores a range of inheritance taxation reforms intended to address wealth inequality while providing recurring funds for public services and redistribution.
Travelling wave charges lying on the insulating walls of an electrolyte-filled capillary give rise to oscillatory modes which vanish when averaged over the period of oscillation. They also give rise to a zero mode (a unidirectional, time-independent velocity component) which does not vanish. The latter is a nonlinear effect caused by continuous symmetry breaking due to the quadratic nonlinearity associated with the electric body force in the time-dependent Stokes equations. In this paper, we provide a unified view of the effects arising in boundary-driven electrokinetic flows (travelling wave electroosmosis) and establish the universal behaviour exhibited by the observables. We show that the incipient velocity profiles are self-similar implying that those obtained with a single experimental configuration can be employed again to attain further insights without the need of repeating the experiment. Certain results from the literature are recovered as special cases of our formulation and we resolve certain paradoxes having appeared in the past. We present simple theoretical expressions, depending on a single-fit parameter, that reproduce these profiles, which could thus provide a rapid test of consistency between our theory and future experiment. The effect becomes more pronounced when reducing the transverse dimension of the system, relative to the velocity direction, and increasing the excitation wavelength, and can therefore be employed for unidirectional transport of electrolytes in thin and long capillaries. General relations, expressing the zero mode velocity in terms of the electric potential and the geometry of the system only, can thus be easily adapted to alternative experimental settings.
The duration of undiagnosed or untreated bipolar disorder (DUBD) has become a focus of research interest. However, its relationship with clinical characteristics and outcomes remains poorly understood.
Aims
The objective of this systematic review and meta-analysis was to examine DUBD and explore its relationships with clinical characteristics and outcomes in bipolar disorder.
Methods
We conducted a systematic search of the literature to identify studies reporting on DUBD and its relationships with clinical characteristics and outcomes including frequency of relapse into mood episodes, severity and persistence of mood symptoms, functional and cognitive measures, suicidality, hospital admission rate, and comorbidities such as substance use disorders.
Results
Thirty articles met inclusion criteria for the systematic review, and 23 studies were included in the three different sets of meta-analyses. The pooled mean DUBD across all studies was 9.10 years. Early onset, depression as the polarity of the first mood episode, lifetime suicide attempts, comorbid anxiety and alcohol use disorders, and family history of bipolar disorder were associated with significantly longer DUBD, whereas diagnosis of bipolar I disorder and lifetime psychotic symptoms were associated with shorter DUBD. Studies that investigated outcomes subsequent to the diagnosis of bipolar disorder yielded conflicting results.
Conclusion
DUBD may be associated with certain adverse outcomes. This association indicates the importance of adopting a more comprehensive approach to assessing mood disorders, with an emphasis on prioritising early screening for bipolar disorder. The significant heterogeneity among included studies suggests a need for improved methodological rigour in future research.
Syllable integrity, the idea that the content of syllables may not be metrified separately, is often taken to be an inviolable constraint of grammar. This has been challenged in recent work, though the data are often subject to competing analyses. This article claims that syllable integrity is readily violable in Naasioi. Evidence from stress, the minimal word and metrically sensitive allomorphy supports an analysis of the metrical system operating on bimoraic feet, and in which long vowels can be metrified separately. Despite this, there is also evidence, in the form of vowel shortening and truncation, to indicate that long vowels constitute a single syllable. The net result is a stress system which systematically ignores syllables, a state of affairs which allows for syllable integrity violations to arise.
Knowledge about HIV and level of HIV-related stigma have been considered the main indicators of the community’s readiness to combat and bring the HIV epidemic to an end. Of all Serbia, the northern Kosovo province is especially vulnerable to the HIV spread because the infrastructure and the entire regulatory system had to be rebuilt after the ethnic conflict. The study objective was to examine the association between HIV-related knowledge level and attitudes towards people living with HIV (PLHIV) among university students from northern Kosovo using the quantile regression. A total of 1,017 students filled in an anonymous questionnaire. The questionnaire examined socio-demographic characteristics, HIV-related knowledge, attitudes towards PLHIV, sources of information about HIV, past experiences with PLHIV, and health behaviours. The dependent variable in the model was the attitude score (ATS) divided into quantiles (Q) in quantile regression analysis: Q0.10, Q0.25, Q0.50, Q0.75, and Q0.90. The independent variable was the knowledge score (KNS). The model was adjusted for relevant covariates. The majority of students had adequate HIV-related knowledge (89.6%) and 10.4% had lower knowledge. Most students also had a positive attitude (83.9%), while 16.1% were indecisive towards PLHIV. No students exhibiting wrong knowledge and negative attitudes were observed. The KNS and ATS significantly correlated with one another (ρ = 0.383; p = 0.001). The quantile regression model adjusted for variables associated with both KNS and ATS showed a negative association between KNS and ATS in the lowest quantile (Q0.10) of the ATS. In all other quantiles (Q0.25–Q0.90), a higher KNS was associated with having stronger positive attitudes towards PLHIV. This study confirmed that higher knowledge about HIV was associated with stronger positive attitudes towards HIV. Still, some students remain indecisive despite being knowledgeable about HIV. These students could benefit the most from continuing educational programmes to reduce the HIV-related stigma.
