We are delighted to celebrate the 20th anniversary of Politics & Gender. This achievement signals an inflection point in the maturity of the subfield of women, gender, and politics research, and provides us with an opportunity to reflect on the role that the journal has played in the discipline of political science.
Predicting and perhaps mitigating against rare, extreme events in fluid flows is an important challenge. Due to the time-localised nature of these events, Fourier-based methods prove inefficient in capturing them. Instead, this paper uses wavelet-based methods to understand the underlying patterns in a forced flow over a 2-torus which has intermittent high-energy burst events interrupting an ambient low-energy ‘quiet’ flow. Two wavelet-based methods are examined to predict burst events: (i) a wavelet proper orthogonal decomposition (WPOD) based method which uncovers and utilises the key flow patterns seen in the quiet regions and the bursting episodes; and (ii) a wavelet resolvent analysis (WRA) based method that relies on the forcing structures which amplify the underlying flow patterns. These methods are compared with a straightforward energy tracking approach which acts as a benchmark. Both the wavelet-based approaches succeed in producing better predictions than a simple energy criterion, i.e. earlier prediction times and/or fewer false positives and the WRA-based technique always performs better than WPOD. However, the improvement of WRA over WPOD is not as substantial as anticipated. We conjecture that this is because the mechanism for the bursts in the flow studied is found to be largely modal, associated with the unstable eigenfunction of the Navier–Stokes operator linearised around the mean flow. The WRA approach should deliver much better improvement over the WPOD approach for generically non-modal bursting mechanisms where there is a lag between the imposed forcing and the final response pattern.
Eich’s book is a tour de force. It takes us through six episodes in which the history of political theory and the history of political economy intersect through the topic of money. From Aristotle to Locke and Fichte and then through to Marx and Keynes before a final episode costarring Hayek, Rawls, Habermas, and Walzer, we are treated to a fascinating set of reflections on what money is and should be, each articulated in the face of a particular historical crisis. This approach gives us a new way of thinking about what is salient in the history of political thought, but it also helps us think about the present. Eich hopes to move us beyond narrow debates over the depoliticization of money by insisting that money is always already political even when it announces itself as antipolitical, so that the real question is which conception of political life—which values but also which underlying social theory—we want to be embedded in monetary institutions. In explicitly tethering his patient, detailed historical scholarship to the broader goal of stimulating and invigorating reflection on one of the central issues of our own day, Eich tries to overcome the divide between historical work and contemporary debate.
Historical research on efforts to reduce the stigma associated with venereal disease (VD) generally dates these campaigns back to the 1930s. Within the United States, one of the earliest attempts to detach VD from its traditional association with sexual immorality occurred during the late nineteenth- and early twentieth-century, when the New York City dermatologist Lucius Bulkley coined the term syphilis insontium (‘syphilis of the innocent’) in the hopes of demonstrating that many of those who contracted this disease did so through non-sexual contact. Gaining widespread acceptance within the medical community, Bulkley’s ideas served as the intellectual foundation for a discursive assault on the prevailing belief that syphilis constituted the ‘wages of sin’—one designed to destigmatise the disease and to promote more scientific responses to it. However, the effects of this anti-stigma rhetoric were often counterproductive. Encouraging doctors to discern ‘innocence’ or ‘guilt’ through assessments of a patient’s character, syphilis insontium often amplified the disease’s association with immorality. With the passage of time, physicians became increasingly aware of these problems, and in the 1910s, a backlash against Bulkley’s ideas emerged within the American medical community. Yet even with the resultant demise of his destigmatisation campaign, discourses of ‘innocent syphilis’ continued to circulate, casting a long shadow over subsequent stigma reduction efforts.
This study investigated factors influencing the citations of highly cited applied linguistics research over two decades. With a pool of 302 of the top 1% most cited articles in the field, we identified 11 extrinsic factors that were independent of scientific merit but could significantly predict citation counts, including journal-related, author-related, and article-related features. Specifically, the results of multiple linear regression models showed that the time-normalized article citations were significantly predicted by the number of authors, subfield, methodology, title length, CiteScore, accessibility, and scholar h-index. The remaining factors did not exhibit any statistical significance, including the number of references, funding, internationality, and geographical origin. The combined predictive power of all these factors (R²=.208, p<.05) verifies the role of nonscientific factors contributing to high citations for applied linguistics research. These results encourage applied linguistics researchers and practitioners to recognize the underlying forces affecting research impact and highlight the need for a reward system that exclusively favors sound academic practices.
Speaking truth ought to be normative in churches, and yet when it does, the foundations and structures of power are often shaken to the core. This paper explores the issues of identity and integrity in ecclesiology and is concerned with the ethical paradigms and moral frameworks that need to be in place if churches are to be places where honesty and truthfulness can be normative. Churches often fail as institutions because they presume they can conduct their affairs as organizations might. Churches become anger-averse, resisting the voices and experiences of victims, in order that the flow of power and its structures are unimpeded. At that point, churches become inherently committed to re-abusing victims and are unable to hear their pain and protests, which only leads to the perpetration of further abuse.
The three-dimensional stability of two-dimensional natural convection flows in a heated, square enclosure inclined to the horizontal is investigated numerically. First, the computational procedure is validated by comparison of base flow solutions to results reported in literature across a range of inclinations. A bi-global linear stability analysis is then conducted to investigate the stability of these two-dimensional base flows to infinitesimal three-dimensional perturbations, and the effect that buoyancy forces (defined by a buoyancy number $R_N$) and enclosure inclination $\theta$ have on these stability characteristics. The flow is first observed to become three-dimensionally unstable at buoyancy number $R_N = 213.8$ when $\theta$ is $180^\circ$; this increases to $R_N = 2.54 \times 10^4$ at inclination $\theta =58^\circ$. It is found that the two-dimensional base flow is more unstable to three-dimensional perturbations with the critical $R_N$ corresponding to three-dimensional instability being significantly lower than its two-dimensional counterpart across all considered inclinations except $83^\circ \leq \theta \leq 88^\circ$, where the most unstable mode is a two-dimensional oscillatory mode that develops in the boundary layers along the conducting walls. Eight different leading three-dimensional instability modes are identified, with inclinations $58^\circ \leq \theta < 88^\circ$ transitioning through an oscillatory mode, and inclinations $88^\circ \leq \theta \leq 180^\circ$ transitioning through a stationary mode. The characteristics of the primary instability modes corresponding to inclinations $88^\circ \leq \theta \leq 179^\circ$ indicate the presence of a Taylor–Görtler instability.
We obtain a system of identities relating boundary coefficients and spectral data for the one-dimensional Schrödinger equation with boundary conditions containing rational Herglotz–Nevanlinna functions of the eigenvalue parameter. These identities can be thought of as a kind of mini version of the Gelfand–Levitan integral equation for boundary coefficients only.
Yeast frataxin (Yfh1) is a small natural protein from yeast that has the unusual property of undergoing cold denaturation at temperatures above the freezing point of water when under conditions of low ionic strength. This peculiarity, together with remarkable resilience, allows the determination, for the whole protein as well as for individual residues, of the stability curve, that is the temperature dependence of the free energy difference between the unfolded and folded forms. The ease of measuring stability curves without the need to add denaturants or introduce ad hoc destabilizing mutations makes this protein an ideal ‘tool’ for investigating the influence of many environmental factors on protein stability. The present review aims at recapitulating all the open questions that Yfh1 has helped to address, including understanding the differences and commonalities of the cold, heat and pressure unfolded states. This protein thus offers a unique tool for studying aspects of protein stability so far been considered difficult to assess and provides important guidelines that could allow the identification of other similar systems.
Sex work is highly gendered, with 80 percent of sex workers being female, and the vast majority of buyers of sex being male. It is often taken for granted that this is how it is, and implicit in much of the debate around sex work is the assumption that it is inherently gendered. In this paper, I question this assumption, drawing on sociological research to challenge arguments which purport that it is inconceivable that women would ever want to pay for sex, or that sex work would exist under conditions of gender equality. I argue that gendered sexual norms likely are a significant reason for why sex work is so gendered, but sex work would probably continue to exist under conditions of gender equality, due to the diversity in motivations people have for buying and selling sex. Acknowledging that sex work is not inherently gendered is important for (at least) two reasons. First, it is probable that the gendered nature of sex work contributes to the stigma and bad treatment that sex workers, particularly female ones, face. Secondly, if sex work is not inherently gendered, this will have implications for how we should think about it, morally, practically, and legally.
Surface flow of freshwater on Adriatic islands is rare due to the extreme permeability of the karst terrain. Hence, most helminthological studies of freshwater fishes in the Adriatic drainage have focused on mainland freshwater systems, while data from islands are scarce. We collected minnow, Phoxinus lumaireul (Schinz, 1840), specimens in the Suha Ričina stream on Krk Island and screened them for helminth ectoparasites. Identification of metacercariae cysts (black spots) was carried out by sequencing part of the 28S rDNA gene, and a single monogenean worm was identified by sequencing part of the internal transcribed spacer 2 (ITS2). To estimate the level of infection, the number of black spots was counted to calculate prevalence, mean abundance, and mean intensity. Phylogenetic inference based on maximum likelihood and Bayesian inference revealed a rare black spot disease taxon, genus Uvulifer, which represents one of the first records in Europe on fish (second intermediate host), a first record from a Phoxinus host, a first record for the Adriatic drainage and Croatia, and a first record for Southern Europe in general. Furthermore, the monogenean was identified as Gyrodactylus sp., potentially representing a new species.
Drawing on Roman Catholic and ecumenical expertise, this article takes an honest look at the experiences and hopes of those abused. Many in the churches assume that victims seek financial compensation or legal redress. However, research indicates that many victims primarily seek truth and justice as a means of closure and that their struggles with church leadership arise when truth and justice are repeatedly withheld. This makes forgiveness near-impossible and often results in the victim being re-traumatized by the systemic re-abuse they experience. Ultimately, there is no substitute for full and genuine meeting with victims, which requires the church to lay aside its power and authority and engage with humility and proper deference to the victims abused at the hands of the church. Without such openness, the victims cannot move on, and neither can the churches.
Currently, there is limited available information on the epidemiology of parasitic infections in captive non-human primates (NHPs) and their zoonotic potential. However, numerous cases of helminth infections in NHPs have been documented in several zoos around the world, with one of the most prevalent being those of the genus Trichuris. The main objective of this study is to investigate the occurrence of infection by Trichuris spp. in primates from zoological gardens in Spain and to ascertain, at the species level, the specific Trichuris species harbored by these hosts by using mitochondrial and ribosomal markers. A total of 315 stools collected from NPHs (n = 47) in the 13 zoological gardens analyzed yielded a prevalence rate of 19.05%. Nevertheless, not all the zoos exhibited parasitic infections; this was observed in only 53.85% of the zoos. Moreover, 15 host groups of 12 different species were found to be infected by Trichuris species, among which the identified species included Trichuris trichiura, Trichuris colobae, and Trichuris sp. Our findings suggest a substantial exposure of primates to zoonotic Trichuris species, suggesting that NHPs could potentially act as reservoirs capable of transmitting this parasite to humans. Hence, it is crucial to implement additional control and prevention measures and explore ways to eradicate parasitic infections in these areas. Further examination is warranted to minimize the risk of spreading drug-resistant parasite strains.
