In this paper, the authors explore the question of whether cognitive enhancement via direct neurostimulation, such as through deep brain stimulation, could be reasonably characterized as a form of transformative experience. This question is inspired by a qualitative study being conducted with people at risk of developing dementia and in intimate relationships with people living with dementia (PLWD). They apply L.A. Paul’s work on transformative experience to the question of cognitive enhancement and explore potential limitations on the kind of claims that can legitimately be made about individual well-being and flourishing, as well as limit the kind of empirical work—including the authors’ own—that can hope to enlighten ethical discourse. In this paper, the authors advance the following theses: (1) it is sometimes reasonable to characterize cognitive enhancement as a transformative experience; (2) the testimonies of people intimately acquainted with dementia may still be relevant to evaluating cognitive enhancement even though cognitive enhancement may be a transformative experience; and (3) qualitative studies may still be useful in the ethical analysis of cognitive enhancement, but special attention may need to be given to how these are conducted and what kind of insights can be drawn from them.

The neoliberal globalization project of expanding and maintaining capitalism globally requires the shaping of neoliberal nation-states that will entrench its ideology, political structures, and practices. In that sense, the neoliberal nation-state provides an appropriate conceptual site for investigating the local-global nexus in the dynamics of global capitalism. Using the Philippines as an example, this paper investigates the various factors or dimensions in the making of the Philippines as a neoliberal nation-state from the colonial era to the supranational structures that exert external control on the Philippine political economy: the global power of transnational corporations, the IMF, American and Chinese imperialism, including the American military aid that supports militarization and counter-insurgency against movements that challenge the neoliberal agenda of the past and current regimes. In addition, this paper offers implications for policy changes and strategies for global resistance that anti-globalization movements can consider.

Recent studies have shown that watching videos with dual subtitles can promote vocabulary learning. This study investigated the extent to which vocabulary learning may be enhanced through repeated viewings of dual-subtitled videos. A 3x3 counterbalanced experimental design was adopted to examine English as a foreign language (EFL) learners’ immediate vocabulary gains and retention under different learning conditions across three experimental sessions, including (a) immediate repeated viewing, (b) spaced repeated viewing, and (c) no repeated viewing. Participants were 60 Chinese-speaking lower-intermediate university EFL learners. They were divided into three groups and given each of the three treatments in each experimental session. ANOVA results revealed that viewing dual-subtitled videos with repetition allowed learners to achieve greater vocabulary gains than viewing with no repetition, with evidence indicating the superiority of immediate repetitions over spaced repetitions.

Starting in the 1970s, the “ex-gay movement,” a loose collection of conservative Christian counselors and therapists, experienced sizable growth in the United States. Importantly, women played a prominent role in the expansion of the ex-gay movement in the ensuing decades, both as counselors and as counselees. This article highlights the tension that arose between the patriarchal gender norms and the role women counselors played in the ex-gay movement. When read “along the grain,” ex-gay texts demonstrate the production of a gendered hierarchy that not only valued “female femininity” over “female masculinity” but also reified patriarchal authority in the US. Female pastoral counselors, such as Leanne Payne and Elizabeth Moberly, advocated for the conservative gendered vision of the religious right. But as women, these counselors—and their books—could not transcend the patriarchal order of the religiously conservative ex-gay movement.

We develop a physics-informed neural network (PINN) to significantly augment state-of-the-art experimental data of stratified flows. A fully connected deep neural network is trained using time-resolved experimental data in a salt-stratified inclined duct experiment, consisting of three-component velocity fields and density fields measured simultaneously in three dimensions at Reynolds number $= O(10^3)$ and at Prandtl or Schmidt number $=700$. The PINN enforces incompressibility, the governing equations for momentum and buoyancy, and the boundary conditions at the duct walls. These physics-constrained, augmented data are output at an increased spatio-temporal resolution and demonstrate five key results: (i) the elimination of measurement noise; (ii) the correction of distortion caused by the scanning measurement technique; (iii) the identification of weak but dynamically important three-dimensional vortices of Holmboe waves; (iv) the revision of turbulent energy budgets and mixing efficiency; and (v) the prediction of the latent pressure field and its role in the observed asymmetric Holmboe wave dynamics. These results mark a significant step forward in furthering the reach of experiments, especially in the context of stratified turbulence, where accurately computing three-dimensional gradients and resolving small scales remain enduring challenges.

This article suggests that Henry, third Earl Grey, had a vision of a liberal British world, which he hoped to implement through a political career. It was based on strong executive governance, representative politics, and the abolition of protection and slavery. It relied on the free market and good race relations to bring progress. He rejected the idea that legislation could impose improvement on colonial peoples. His program was quickly derailed, because of turbulent representative politics in Britain and the colonies after 1848. Later political developments made any integrated liberal vision of empire even more impractical. Studying Grey's arguments, and their fate, can help the task of defining British imperial liberalism. It is best understood as an attempt to check (Tory) vested interests, rather than as an ideology of interventionist improvement. Its priorities and tensions make most sense in relation to the concepts, assumptions, and turning points that dominated British politics.

This article concerns the role of covenant in early rabbinic literature in relation to biblical and especially Second Temple-era predecessors. The first part establishes that the Qumran sectarians and earlier circles were drawn to the concept of covenant because it represented, especially through the mechanism of covenant renewal, a powerful tool for defining and supporting group identity. The second part shows that for the rabbis, the importance of covenant lay chiefly, instead, in its capacity to conceptualize the notion of Israel as a collective body defined by corporate responsibility. The third part suggests that this novel deployment of covenant arose in part to counter the individuating force of halakah as law, another innovation of the rabbis.

The purpose of this paper is to (a) develop a comprehensive understanding of the relationships between person–environment (PE) fit and employee engagement by shedding light on their intervening mechanisms; (b) represent how different types of PE fit and employee engagement interact; and (c) establish a comprehensive theoretical framework to guide future research based on the empirically examined constructs and their relationships. An integrative literature review of 51 empirical papers which analyzed the relationship between PE fit and employee engagement suggests that the antecedents of the relationship exist at the organizational, group, and individual levels and can be conceptualized as socialization, relationship building, and personal character, respectively; values–supplies fit, needs–supplies fit, and demands–abilities fit act as intervening mechanisms in the relationship; the relationship is temporal, reciprocal, and facilitated by human agency; and various outcomes result from the relationship. Implications for future research and practice are also discussed.

Developmental psychopathology has successfully advanced an understanding of risk and protective factors in multivariate models. However, many areas have relied on top-down approaches that define psychological constructs based largely or solely on their physical form. In this paper, we first describe how top-down approaches have significantly hindered progress by generating generic risk and protective models that yield little more than the conclusion that axiomatically positive and negative factors respectively beget an interchangeable array of positive and negative child sequelae. To advance precision and novelty as central priorities, we describe behavioral systems frameworks rooted in evolutionary theory that infuse both form (i.e., what it looks like) and function (what it is designed to do) into psychological constructs. We further address how this paradigm has generated new growing points for developmental models of interparental relationships and parenting. In the final section, we provide recommendations for expanding this approach to other areas of developmental psychopathology. Throughout the paper, we document how the focus on functional patterns of behavior in well-defined developmental contexts advance precision and novelty in understanding children’s response processes to threats, opportunities, and challenges in associations between their developmental histories and their psychological sequelae.

Centrality measures aim to indicate who is important in a network. Various notions of ‘being important’ give rise to different centrality measures. In this paper, we study how important the central vertices are for the connectivity structure of the network, by investigating how the removal of the most central vertices affects the number of connected components and the size of the giant component. We use local convergence techniques to identify the limiting number of connected components for locally converging graphs and centrality measures that depend on the vertex’s neighbourhood. For the size of the giant, we prove a general upper bound. For the matching lower bound, we specialise to the case of degree centrality on one of the most popular models in network science, the configuration model, for which we show that removal of the highest-degree vertices destroys the giant most.

Single-particle cryogenic electron microscopy (cryo-EM) is an imaging technique capable of recovering the high-resolution three-dimensional (3D) structure of biological macromolecules from many noisy and randomly oriented projection images. One notable approach to 3D reconstruction, known as Kam’s method, relies on the moments of the two-dimensional (2D) images. Inspired by Kam’s method, we introduce a rotationally invariant metric between two molecular structures, which does not require 3D alignment. Further, we introduce a metric between a stack of projection images and a molecular structure, which is invariant to rotations and reflections and does not require performing 3D reconstruction. Additionally, the latter metric does not assume a uniform distribution of viewing angles. We demonstrate the uses of the new metrics on synthetic and experimental datasets, highlighting their ability to measure structural similarity.

Self-sustained, low-frequency, coherent flow unsteadiness over rigid, stationary aerofoils in the transonic regime is referred to as transonic buffet. This study examines the role of shock waves in sustaining this transonic phenomenon and its relation to low-frequency oscillations (LFO) that occur in flow over aerofoils in the incompressible regime (Zaman et al., J. Fluid Mech., vol. 202, 1989, pp. 403–442). This is investigated by performing large-eddy simulations of the flow over a NACA0012 profile for a wide range of flow conditions under free-transition conditions. At low Reynolds numbers, zero incidence angle and sufficiently high free-stream Mach numbers, $M$, transonic buffet occurs with shock waves present in the flow. However, when $M$ alone is lowered, self-sustained, periodic oscillations at a low frequency are observed even though shock waves are absent and the entire flow field remains subsonic at all times. At higher incidence angles, the oscillations are sustained at progressively lower $M$ and are present even at $M=0.3$, where compressibility effects are low. A spectral proper orthogonal decomposition (SPOD) shows that the spatial structure of these oscillations is consistent for all cases. The SPOD modes are topologically similar, suggesting a connection between transonic buffet and LFO in the incompressible regime. Comparisons with other studies examining transonic buffet on various aerofoils, under forced-transition and fully turbulent conditions support this hypothesis. Future studies using tools of global linear stability analysis, especially at high free-stream Reynolds numbers are required to examine whether the underlying mechanisms of transonic buffet and incompressible LFO are the same.

We analyse the results of direct numerical simulations of rotating convection in spherical shell geometries with stress-free boundary conditions, which develop strong zonal flows. Both the Ekman number and the Rayleigh number are varied. We find that the asymptotic theory for rapidly rotating convection can be used to predict the Ekman number dependence of each term in the governing equations, along with the convective flow speeds and the dominant length scales. Using a balance between the Reynolds stress and the viscous stress, together with the asymptotic scaling for the convective velocity, we derive an asymptotic prediction for the scaling behaviour of the zonal flow with respect to the Ekman number, which is supported by the numerical simulations. We do not find evidence of distinct asymptotic scalings for the buoyancy and viscous forces and, in agreement with previous results from asymptotic plane layer models, we find that the ratio of the viscous force to the buoyancy force increases with Rayleigh number. Thus, viscosity remains non-negligible and we do not observe a trend towards a diffusion-free scaling behaviour within the rapidly rotating regime.

Variations in sagittal otolith shape and morphometry, including length (Lo), width (Wo), area (Ao), and perimeter (Po), were investigated in two populations of Chelon ramada collected from the Boughrara and El Bibane lagoons located in southeastern Tunisia. The objective was to assess the geographic variation in the sagittal otoliths' shape and morphometry and the effect of potential fluctuating asymmetry (FA) in morphometry on the stock structure of C. ramada in the two lagoons to inform on appropriate management procedures. At the interpopulation level, analysis of sagittal otolith shape showed a statistically significant difference (P = 0.0001), i.e. there was a bilateral asymmetry, in the shape of left and right otoliths between individuals of the two populations. In addition, significant FA was found only in Lo between the left and right otoliths. At the intrapopulation level, a significant shape difference (P < 0.0001), particularly asymmetry, was observed in both left and right otoliths between males and females, indicating sexual dimorphism in shape within the Boughrara lagoon. However, significant shape similarity, i.e. symmetry, was observed in the left and right otoliths among individuals of the El Bibane lagoon. Moreover, a significant FA was detected in Lo between the left and right otoliths only among males, as well as between males and females of the Boughrara lagoon. However, a significant FA between the left and right otoliths was found only in Wo among males and in all morphometric dimensions among females and Wo between males and females of the El Bibane lagoon. Discriminant function analysis of the otolith contour shape confirmed the presence of two separate C. ramada stocks, one corresponding to the Boughrara lagoon and the other representing the El Bibane lagoon, which should be managed separately. The possible cause of morphological variation in the sagittal otoliths' shape and morphometry due to FA between individuals of the two populations was discussed in relation to the biotic and abiotic factors.
