Financial literacy is a dangerous illusion. The article builds on existing critiques, notably the work of Lauren Willis, to show that the discourse of financial literacy education raises fundamental epistemological issues about the nature of financial markets and financial behaviour. The difficulties of achieving financial literacy are ill conceived simply as the outcomes of market imperfections. Instead, structural inequalities, financial reform, and the nature of financial assets preclude consumers from achieving adequate levels of financial competence and the claim that they can do so diverts attention from the causes of unequal economic outcomes.
The past two decades have witnessed Macao’s development into the casino capital of the world. Casinos have significantly transformed all respects of Macao society—a phenomenon termed as the casinoization of Macao. While much research has explored how casinoization has affected Macao’s socioeconomic developments, empirical research on the relationship between casinoization and law enforcement agencies is extremely limited. Using official statistics and interviews with serving and retired police officers as well as police applicants in Macao, this article examines the quick-money mentality, laissez-faire regulation, and the paradox of plenty, three features of casinoization, and their profound impact on the Macao police. First, the early phase of casino liberalization created a draining effect on human capital from the police force. Second, the lucrative casino tax revenues empowered the government to resolve the labour shortage issue and significantly improve the police image. Third, casinoization inadvertently reinforced the colonial legacy of laissez-faire regulation, hampering the progress of institutional reforms. Fourth, the decline of casino has contributed to the unprecedented “police fever” among the youth in Macao.
Cavitation inception in the turbulent shear layer developing behind a backward-facing step occurs at multiple points along quasi-streamwise vortices (QSVs), at a rate that increases with the Reynolds number (Re). This study investigates the evolution of the unsteady pressure field and the distribution of nuclei within and around the QSVs. The time-resolved volumetric velocity in the non-cavitating flow is measured using tomographic particle tracking, and the pressure is determined by spatial integration of the material acceleration. Analysis in Eulerian and Lagrangian reference frames reveals that the pressure is lower, and its minima last longer within the QSVs compared with the surrounding flow. The intermittent low pressure regions, whose sizes and shapes are consistent with those of the cavities, are likely to be preceded by axial vortex stretching and followed by contraction. Such phenomena have been observed before in simulations of stretched vortex elements. For the same axial straining, the pressure minima last longer with increasing Re, a trend elucidated in terms of viscous diffusion of the stretched vortex core. The impact of nuclei availability is studied under ‘natural’ and controlled seeding. Owing to differences in the saturation level of non-condensable gas, the microbubble concentration in the shear layer decreases with increasing Re, in contrast to the rate of cavitation events. Minor differences in entrainment rate into the shear layer also do not explain the substantial Re effects on cavitation inception. Hence, the Re scaling of inception appears to be dominated by trends of the pressure field.
In the 1970s and 1980s, Soviet social scientists and planners grew increasingly skeptical that they could draw Central Asian peasants, and especially women, into the industrial workforce, and turned to experimenting with “non traditional” forms of work, such as home labor for handicrafts and consumer goods and family subcontracting in agriculture. This article traces Soviet debates about women’s labor and the family in Central Asia in the context of demographic policy, productivity, and welfare. It argues that the evolution of home labor and other “non traditional” labor policies aimed at Central Asians share two distinctive features with neoliberal-inspired welfare discussions in the United States as well as the emerging politics of entrepreneurship in the sphere of international development. First, all three emerged as a result of social scientists and planners revisiting earlier paradigms after perceived policy failures. Second, despite their pessimistic reading of earlier policy initiatives, Soviet policymakers and their counterparts hung on tenaciously to the idea that state policy could be used to improve people’s lives. By studying the turn towards individual labor and entrepreneurship in the USSR alongside the emergence of micro-credit in international development and changing welfare politics in the US, we can see neoliberalism emerging where universalist policies meet their limits.
Success semantics holds, roughly, that what it is for a state of an agent to be a belief that P is for it to be disposed to combine with her desires to cause behaviour that would fulfill those desires if P. J. T. Whyte supplements this with an account of the contents of an agent's “basic desires” to provide an attractive naturalistic theory of mental content. We argue that Whyte's strategy can avoid the objections raised against it by restricting “basic desires” to sensory inclinations that cause us to do things independently of our beliefs about their contents.
Active emulsions can spontaneously form self-propelled droplets or phoretic micropumps. However, it remains unclear how these active systems interact with their self-generated chemical fields, which can lead to emergent chemodynamic phenomena and multistable interfacial flows. Here, we simultaneously measure the flow and chemical concentration fields using dual-channel fluorescence microscopy for active micropumps, i.e. immobilised oil droplets that dynamically solubilise in a supramicellar aqueous surfactant solution. With increasing droplet radius, we observe (i) a migration of vortices from the posterior to the anterior, analogous to a transition from pusher- to puller-type swimmers, (ii) a bistability between dipolar and quadrupolar flows and, eventually, (iii) a transition to multipolar modes. We also investigate the long-time dynamics. Together, our observations suggest that a local build-up of chemical products leads to a saturation of the surface, which controls the propulsion mechanism. These multistable dynamics can be explained by the competing time scales of slow micellar diffusion governing the chemical buildup and faster molecular diffusion powering the underlying transport mechanism. Our results are directly relevant to phoretic micropumps, but also shed light on the interfacial activity dynamics of self-propelled droplets and other active emulsion systems.
Twins’ memoirs and autobiographies both enlighten and entertain. These works, often overlooked by researchers, may suggest new avenues for investigation, such as nonshared environmental events that propel twins in different directions. Of course, MZ twins’ generally parallel experiences and DZ twins generally criss-crossing paths are the bases of fascinating life stories. The following sections examined recent research on fetal reduction in twin pregnancy, twins’ personality and military service, growth restriction in twins, and advances in conjoined twin separation. This article closes with reports of a scientist who performed gene editing on twins, a twin conception from 33-year-old embryos, twins’ physical outcomes from dietary differences, fraternal twins with the world’s largest height difference and the Twin Home Experts who conquer rat infestation in New York.
We numerically investigated the global linear instability and bifurcations in electro-thermo-convection (ETC) of a dielectric liquid confined in a two-dimensional (2-D) concentric annulus subjected to a strong unipolar injection. Seven kinds of solutions exist in this ETC system due to the complex bifurcations, i.e. saddle-node, subcritical and supercritical Hopf bifurcations. These bifurcation routes constitute at most four solution branches. Global linear instability analysis and energy analysis were conducted to explain the instability mechanism and transition of different solutions and to predict the local instability regions. The linearized lattice Boltzmann method (LLBM) for global linear instability analysis, first proposed by Pérez et al. (Theor. Comput. Fluid Dyn., vol. 31, 2017, pp. 643–664) to analyse incompressible flows, was extended here to solve the whole set of coupled linear equations, including the linear Navier–Stokes equations, the linear energy equation, Poisson's equation and the linear charge conservation equation. A multiscale analysis was also performed to recover the macroscopic linearized Navier–Stokes equations from the four different discrete lattice Boltzmann equations (LBEs). The LLBM was validated by calculating the linear critical value of 2-D natural convection; it has an error of 1.39% compared with the spectral method. Instability with global travelling wave behaviour is a unique behaviour in the annulus configuration electrothermohydrodynamic system, which may be caused by the baroclinity. Finally, the chaotic behaviour was quantitatively analysed through calculation of the fractal dimension and Lyapunov exponent.
The Algerian military’s response to the 2019–2020 Hirak protests was relatively peaceful. In contrast to its violent repression of protests in 1988, and subsequent coup and civil war in the 1990s, the military showed considerable restraint toward the Hirak. Leveraging a survey of 2,235 self-reported military personnel, I show that the military’s restraint emanated from protesters’ use of nonviolence and fraternization, as well as from a recognition that the military’s more repressive approach in the 1990s was a mistake. At the same time, a priming experiment suggests that the military’s willingness to repress increases when protesters threaten the military’s corporate interests, and when Russia, Algeria’s primary arms supplier, reiterates its support for the regime. Overall, the results show how protester tactics, international reactions, and political learning can condition the military’s repression or restraint during times of unrest.
This article introduces new quantitative fine-tuned indicators to objectively measure political parties’ preferences on gender issues. We assess the validity and reliability of these new empirical indicators by analyzing the relationship between ideology and gender positions in decentralized Spain. Using data collected by the Regional Manifestos Project, which for the first time has incorporated a fully fledged gender domain into its coding scheme for content analysis of regional manifestos, we analyze parties’ gender positions on four fundamental dimensions: welfare and the labor market, violence, representation, and values and identity. The results suggest that there is a persistent left-right divide on the last three dimensions: Spanish left-wing parties score significantly higher than right-wing and regionalist parties. However, ideology does not drive parties’ gender positions on welfare and labor market policies; support for gender equality policies on this dimension is so widespread that it can be considered a “valence issue”—all parties, irrespective of their ideology, endorse the same (positive) position.
The article focuses on the most elaborate of Paula Meehan's ‘Greek’ poems, ‘Flight JIK Olympic Airlines 016 to Ikaria, Greece’ (Painting Rain, 2009), inspired by her journey to Ikaria, in the framework of travel writing and ecocriticism. By transforming the matrix of W. H. Auden's ‘Musée des Beaux Arts’, and by representing a specific case of ecopoetry, Meehan's text challenges the precepts of footsteps and vertical travel genres. The comparison between the two poems has been contextualized by the Irish poet's environmental, political and artistic concerns, as well as her other poems, essays and travels in Greece.
Energy-harvesting systems in complex flow environments, such as floating offshore wind turbines, tidal turbines and ground-fixed turbines in axial gusts, encounter unsteady streamwise flow conditions that affect their power generation and structural loads. In some cases, enhancements in time-averaged power generation above the steady-flow operating point are observed. To characterize these dynamics, a nonlinear dynamical model for the rotation rate and power extraction of a periodically surging turbine is derived and connected to two potential-flow representations of the induction zone upstream of the turbine. The model predictions for the time-averaged power extraction of the turbine and the upstream flow velocity and pressure are compared against data from experiments conducted with a surging-turbine apparatus in an open-circuit wind tunnel at a diameter-based Reynolds number $Re_D = 6.3\times 10^5$ and surge-velocity amplitudes up to 24 % of the wind speed. The combined modelling approach captures trends in both the time-averaged power extraction and the fluctuations in upstream flow quantities, while relying only on data from steady-flow measurements. The sensitivity of the observed increases in time-averaged power to steady-flow turbine characteristics is established, thus clarifying the conditions under which these enhancements are possible. Finally, the influence of unsteady fluid mechanics on time-averaged power extraction is explored analytically. The theoretical framework and experimental validation provide a cohesive modelling approach that can drive the design, control and optimization of turbines in unsteady flow conditions, as well as inform the development of novel energy-harvesting systems that can leverage unsteady flows for large increases in power-generation capacities.
Analysing phenological diversity of tropical trees provides a potential tool to detect climate change effects and devise forest management options. In this study, the leaf phenological activity of 28 dominant tree species in a moist sub-tropical hill forest of north-eastern India was examined for a period of 2 years and related to functional traits (i.e. leaf mass per area (LMA) and wood density (WD)). The peak phase of leaf fall occurred in the cool dry period (November to January) with leaf flush peaking in the pre-monsoon period (February to March), but variation was found between species as influenced by their phenological strategy, i.e. evergreen, leaf-exchanging or deciduous (<4 months leafless). Photoperiod and minimum temperature were the environmental factors most strongly correlated with phenological activity, and the synchrony index within species for both phenophases was 0.81. LMA was less in the deciduous species compared with the evergreen species, whereas WD did not differ. LMA was negatively correlated with the length of deciduousness as well as timing of leaf flush and fall indicating that LMA may be more important than WD in influencing phenological patterns in this forest. The study revealed that the phenological diversity of tropical trees is related to changes in environmental variables and has implication for forest management under changing climate. Further study will help in understanding the phenological response of trees to climatic factors and their potential future changes.
We prove the convergence of the Adams spectral sequence based on Morava K-theory and relate it to the filtration by powers of the maximal ideal in the Lubin–Tate ring through a Miller square. We use the filtration by powers to construct a spectral sequence relating the homology of the K-local sphere to derived functors of completion and express the latter as cohomology of the Morava stabiliser group. As an application, we compute the zeroth limit at all primes and heights.
The theist needs a conception of the distinction between doing and allowing because much of the literature focused on the problem of evil attempts to justify (via theodicy) or defend (via defence) God's allowing evil to occur. I present a counterfactual account of the doing/allowing distinction in the divine context and argue that, even if there are compelling objections to counterfactual accounts of the distinction in the human context, they do not work against such an account in the divine context. The counterfactual analysis to follow will allow the theist to plausibly claim that God does not ever bring about evil, which is crucial to some defences against the problem of evil. I conclude by defending my account against possible objections.
Informal caregivers are the core of long-term care for older and disabled people. Although previous research has studied factors that influence caregivers’ burden, little is known about the different care domains and why they influence the caregivers’ perceived burden. Drawing on a large-scale German survey, the current study makes a first attempt to address this research gap. The study used cross-sectional data on 1.429 informal caregivers. Germany is characterized by comprehensive but fragmented health and social protection systems oriented toward supporting informal care at home. Structural equation modeling (SmartPLS 3) was used to estimate the effects of five care domains on three burden dimensions and, ultimately, on the overall burden. Our results indicate that support in organizational matters had the highest impact on the overall perceived burden. The findings reveal that German caregivers particularly struggle with bureaucracy, i.e. an area that can directly be influenced by policymakers.
After seizing power in 1933, the Nazis added photographic denunciation to the repertoire of modern European public shaming practices to forge a new consensus about who belonged in German society. Photographic denunciation, in which Nazi functionaries took and displayed pictures of non-Jewish Germans shopping at Jewish-owned businesses advanced the Nazi dispossession of German Jews while coercing non-Jewish Germans into severing ties with Jewish neighbours . Contrary to what most historical scholarship has implied, photographic denunciation lasted well into the 1930s in Germany and even transcended German borders. Ultimately, photographic denunciation was among the Nazis’ most successful tools to turn non-Jewish Germans against Jews, a key precursor to the ability of the Nazi regime to perpetrate the Holocaust.
Widowhood is often described through stereotypes and images of passive, weak, lonely and dependent women. This study presents additional aspects of widows who have chosen to continue their lives without a new spouse. It thus joins the recently growing body of knowledge which presents widowhood in a less one-dimensional way while referring to the complexity and different layers of widows' lives. A qualitative study was conducted with 30 women aged 63–87 who had been widows for 1–34 years. The findings showed that the dominant experience shared by all women is one of liberation and freedom – a feeling of independence that is expressed socially, personally and economically. Thus, alongside feelings of loneliness and adaptation difficulties, they also experience strength and empowerment. The term ‘gender contract’ serves as a theoretical explanation of the independence narrative that characterises the widows; the termination of the couple's gender contract allows them to redefine their priorities, identify themselves as active instead of passive figures and create for themselves a place of their own. By bringing widowhood to the centre of the discussion, the study gives legitimacy to a discourse on feelings less spoken about, such as relief, freedom and independence. In this way, the study contributes to the ongoing debate on widows by shattering the accepted myth of widows as vulnerable, weak and dependent but without underestimating the difficulties or ignoring the women's diversity.
In this study, the transport equation for scalar iso-surface area density ($\varSigma$) in a turbulent, temporally developing mixing layer is examined. Exploring the spatial and temporal evolution of the terms in the $\varSigma$ transport equation is vital to improving our understanding of turbulent flows characterized by distinct interfaces, e.g. the flame surface or the turbulent/non-turbulent interface. Previous work reported by the authors identified that $\varSigma$ exhibits self-similar behaviour consistent with the development of the temporal mixing layer (Blakeley et al., J. Fluid Mech., vol. 951, 2022, A44). Accordingly, each of the terms in the $\varSigma$ transport equation is found to behave in a self-similar manner, though there are notable differences in the self-similar behaviours for each term. Based on the results presented herein, it is suggested that the rate of change of $\varSigma$ ($\partial \varSigma /\partial t$) and the advection term scale with $h\lambda _\varPhi /\Delta U$, where $h$ is the width of the mixing layer, $\lambda _\varPhi$ is the scalar Taylor length scale and $\Delta U$ is the velocity difference. The production and destruction terms are found to scale with an additional factor $({Re}\,Sc)^{1/2}$. In contrast, the molecular diffusion term is found to scale with a factor $({Re}\,Sc)^{-1/2}$ compared to $\partial \varSigma /\partial t$. Importantly, it is found that the difference between the production and destruction terms, or net surface ‘stretch’, scales with the same factor as $\partial \varSigma /\partial t$ and the advection term, which may have a significant impact on how the evolution of $\varSigma$ is understood and modelled in turbulent flows.
