Catcalls have been said to insult, intimidate, and silence their targets. The harms that catcalls inflict on individuals are reason enough to condemn them. This paper argues that they also inflict a type of structural harm by subordinating their targets. Catcalling initiates an unwanted conversation where none should exist. This brings the rules and norms governing conversations to bear in such a way that the catcall assigns their target a “subordinate discourse role.” This not only constrains the behavior of the target here and now, but also influences the norms governing future conversations. Catcalls are then not only bad because of the effects on their target, but also because of their pernicious contribution to the wider normative landscape.
Air-blast atomizers are extensively used for a variety of purposes. Due to its complexity, the atomization mechanism has not been elucidated. In this study, a mechanistic model is proposed to predict the droplet diameter distribution based on the atomization process of a planar liquid film with co-current gas flows, and its validity is examined by comparing the estimated and measured droplet diameters using high-speed image analysis and laser measurement. As a result, using high-speed imaging, we clarified that the bag film rupture is caused not by the turbulence of the gas flow but by the impact of floating droplets on the liquid film of the expanding bag when the film is thin enough. The average thickness of the liquid film at the bag breakup is of the order of micrometres and varies greatly, resulting in a dispersed distribution of droplet diameters. After the film ruptures, the bag film shrinks towards its transversal and vertical rims due to surface tension, forming large-diameter ligaments. During the contraction process of the bag film, tiny droplets of the order of micrometers are formed at the edge of the perforation. Finally, the remaining ligaments with large diameters fragment into large droplets with submillimetre diameters. The good agreement between the measured and predicted droplet diameter distributions validated the mechanistic model.
Despite its low prevalence, the potential diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT) should be at the forefront of a paediatric cardiologists mind in children with syncope during exercise or emotions. Over the years, the number of children with a genetic diagnosis of CPVT due to a (likely) pathogenic RYR2 variant early in life and prior to the onset of symptoms has increased due to cascade screening programmes. Limited guidance for this group of patients is currently available. Therefore, we aimed to summarise currently available literature for asymptomatic patients with a (likely) pathogenic RYR2 variant, particularly the history of CPVT and its genetic architecture, the currently available diagnostic tests and their limitations, and the development of a CPVT phenotype – both electrocardiographically and symptomatic – of affected family members. Their risk of arrhythmic events is presumably low and a phenotype seems to develop in the first two decades of life. Future research should focus on this group in particular, to better understand the development of a phenotype over time, and therefore, to be able to better guide clinical management – including the frequency of diagnostic tests, the timing of the initiation of drug therapy, and lifestyle recommendations.
To determine prevalence of technical and behavioral interventions aimed at preventing central line-associated bloodstream infection (CLABSI) following the COVID19 pandemic.
Design:
Cross-sectional survey.
Setting:
US acute care hospitals.
Participants:
Infection preventionists at participating hospitals.
Methods:
Surveys were sent to infection preventionists from a national random sample of 881 US acute care hospitals. Questions covered use of technical interventions to prevent CLABSI (eg, alcohol-containing chlorhexidine gluconate [CHG] for skin antisepsis, use of coated catheters), socio-adaptive interventions (eg, feedback of CLABSI rates, use of appropriateness criteria), and leadership support for CLABSI prevention.
Results:
Survey response rate was 47% (415/881). Technical interventions such as maximal sterile barriers (99%) or CHG-impregnated dressings (92%) were highly prevalent, but routine use of CHG bathing was less common (68% indicated regular use in intensive care unit [ICU] vs 18% in non-ICU settings). Although 97% of respondents indicated use of systems to monitor CLABSI, feedback to providers on CLABSI events was reported by 89%. Only 53% of respondents indicated regular use of tools to determine appropriateness of central venous catheters (CVC). Three-quarters of respondents indicated their hospital assessed CVC necessity daily, but only 23% reported strategies to reduce routine blood cultures. CLABSI prevention was extremely important to hospital leadership at 82% of responding hospitals.
Conclusions:
Most US hospitals continue to use evidence-based methods to prevent CLABSI as recommended by leading organizations. Opportunities to focus on socio-adaptive interventions such as feedback of infection rates, use of appropriateness criteria for CVC placement, and improving the “culture of pan-culturing” remain.
While the Europe-wide cultural impact of the fall of Constantinople to Sultan Mehmed II is well known, its political reverberations in the Holy Roman Empire have received comparatively little attention. This article argues that the events of 1453 inaugurated a new dynamic in the empire that facilitated the polity's consolidation and the creation of new collective institutions within it long before Maximilian I (1486–1519), whose reign is often presented as a constitutional turning point. Some prince-electors had been calling for more effective peace-keeping and judicial institutions for decades before 1453 but lacked the leverage to compel kings and emperors of the Romans to accept political change on their terms. The fall of Constantinople provided a focal point for these negotiations: in return for promising to support an anti-Ottoman crusade, the reformists were able to force a compromise on new peace-keeping legislation at the diets of the 1450s and 1460s. This compromise was catalyzed by public pressure. There was a widely held expectation that leading imperial protagonists should fulfill this mission to defend Christendom, manifested in orations, diplomatic missives, poetry and songs, plays, and early printed pamphlets produced within and for a range of German-speaking public spheres.
A rapid nonlinear aeroelastic framework for the analysis of the highly flexible wing with distributed propellers is presented, validated and applied to investigate the propeller effects on the wing dynamic response and aeroelastic stability. In the framework, nonlinear beam elements based on the co-rotational method are applied for the large-deformation wing structure, and an efficient cylinder coordinate generation method is proposed for attached propellers at different position. By taking advantage of the relatively slow dynamics of the high-aspect-ratio wing, propeller wake is modeled as a quasi-steady skewed vortex cylinder with no updating process to reduce the high computational cost. Axial and tangential induced velocities are derived and included in the unsteady vortex lattice method. For the numerical cases explored, results indicate that large deformation causes thrust to produce wing negative torsion which limits the displacement oscillation, and slipstream mainly increases the response values. In addition, an improvement of flutter boundary is found with the increase of propeller thrust while slipstream brings a destabilising effect as a result of the increment of dynamic pressure and local lift. The great potential of distributed propellers in gust alleviation and flutter suppression of such aircraft is pointed out and the method as well as conclusions in this paper can provide further guidance.
Early-life adversity as neglect or low socioeconomic status is associated with negative physical/mental health outcomes and plays an important role in health trajectories through life. The early-life environment has been shown to be encoded as changes in epigenetic markers that are retained for many years.
We investigated the effect of maternal major financial problems (MFP) and material deprivation (MD) on their children’s epigenome in the Avon Longitudinal Study of Parents and Children (ALSPAC) cohort. Epigenetic aging, measured with epigenetic clocks, was weakly accelerated with increased MFP. In subsequent EWAS, MFP, and MD showed strong, independent programing effects on children’s genomes. MFP in the period from birth to age seven was associated with genome-wide epigenetic modifications on children’s genome visible at age 7 and partially remaining at age 15.
These results support the hypothesis that physiological processes at least partially explain associations between early-life adversity and health problems later in life. Both maternal stressors (MFP/MD) had similar effects on biological pathways, providing preliminary evidence for the mechanisms underlying the effects of low socioeconomic status in early life and disease outcomes later in life. Understanding these associations is essential to explain disease susceptibility, overall life trajectories and the transition from health to disease.
In the present study, a comparison of the thermal-insulation and mechanical performances of cement and heat-stabilized compressed earthen blocks (CEBs) was carried out to determine the factors which influence those properties. The raw clays used consist mainly of kaolinite, orthoclase and quartz. The mechanical strength increased with increase in both the amount of cement added and the firing temperature. However, the responses are better for cement-stabilized CEBs. The thermal insulation of fired bricks is greater than that of cement-stabilized bricks. This difference was related to the decrease in porosity and the formation of continuous-surface. The decrease in thermal insulation is mainly related to the formation of continuous-surface in cement-stabilized CEBs, whereas in the fired CEBs, it is due to the modification of pore volume. The mineralogy of the raw clays is statistically correlated to porosity and continuous-surface development that were confirmed as the main factors in the modification of both the mechanical strength and the thermal insulation. In cement-stabilization, the decrease in insulation is due to the development of continuous surface, while for heat-stabilization, mineral transformations during the sintering reduced continuous-surface formation and the insulation was controlled by both radiation and reduced surface conduction. The influence of the mineralogy of the raw material shows that clay content favours the insulation in fired bricks obtained at T ≤ 1000°C, while sand contents favour densification. In contrast, clay contents reduce the mechanical response of cement-stabilized material due to limited cement–clay interactions. In general, the mechanical response is more favourable in cement stabilization, while thermal insulation is better in fired bricks.
At Aur. Vict. Caes. 10.5, the reading lautus should be retained; -que is a dittography and should be deleted. At 13.3, satis should be emended into sagatis. This article also provides a brief analysis of Victor's references to clothing and attempts to explain why he comments on the Dacian costume at 13.3, the only ethnographic reference to clothing in the entire work.
I read Carol Griffiths' article with great interest. This is due in part to being in what I feel is a privileged position as book reviewer for a UK journal, the EL Gazette,1 for whom I have read several titles by authors she references on teacher wellbeing, such as Mercer and Gregersen (2020). I wondered, however, why Brierton and Gkonou (2022) was not listed there as it also deals with issues raised by Griffiths such as how academic managers can help create an environment that reduces stress and mental health problems. It was also interesting to note that Griffiths, like myself, has spent most of her working life involved in English language teaching, almost all of which has taken place in Turkey. Her article also resonated with my own experience as a teacher-educator as it draws upon research carried out in a Turkish context (Griffiths & Sönmez, 2020).
This study aimed to solve the debate over the role and extent of neck dissection to treat any occult nodal metastasis in patients undergoing salvage laryngectomy for recurrent and/or residual squamous cell carcinoma of larynx.
Methods
This was a retrospective study over a time frame of 6 years (2016–2022) of 74 patients who underwent bilateral neck dissection and salvage laryngectomy for recurrent or persistent disease with N0 neck. We calculated the incidence of occult nodal metastasis in ipsilateral and contralateral neck.
Results
Incidence of ipsilateral neck disease was calculated as 8.11 per cent and it was 0 per cent in contralateral neck. Regarding ipsilateral nodal level distribution, level II was the highest at 6.76 per cent, followed by level III at 5.41 per cent. There was 0 per cent metastasis in levels IV and IIb.
Conclusion
In patients undergoing salvage laryngectomy with N0 neck, ipsilateral super selective neck dissection is considered a convenient and oncologically safe option to treat the neck.
Since merchants typically traded between towns, they had to cross legal boundaries on a regular basis. This article discusses one of the instruments they used in order to deal with the challenges of legal pluralism, namely the instalment of proxies. The proxy had to be recognized as a legitimate representative of another merchant and, for that purpose, he carried with him a procuration letter. These letters look remarkably similar considering that they were drafted in different towns across Europe. An analysis of the procurations shows that common rules and norms developed through the constant exchange between merchants and urban authorities.
This article explores peasant women’s labour activism in 1890s Hungary, in the southeastern part of the Habsburg Empire, where repeated harvesters’ strikes and peasant uprisings took place during the second half of the nineteenth and early decades of the twentieth centuries, making it the first centre of agrarian workers’ socialist organizing in Hungary. Informed by a more inclusive approach to women’s activist histories and subaltern studies, this article develops a new perspective on the periodization and geography of the international and Hungarian history of women’s social movements, to contribute to the historiographies of peasant women’s labour activism in the Eastern European countryside.
As a result of unfavorable demographic processes, the pension systems in the Central and Eastern European (CEE) EU countries face significant challenges, which has made the implementation of reforms inevitable in the last decade. Relying on economic theory, this paper analyses the effects of the Hungarian pension reforms in comparison with those of other CEE countries, and discusses the consequences from the point of view of social policy and the sustainability of the pension schemes. We explore the reasons why the reforms in Hungary ultimately did not improve sustainability but rather contributed to dismantling the social care system. Therefore, the Hungarian case provides useful lessons for other countries, and at the same time underlines the importance of automatic adjustment mechanisms. The study pays particular attention to the theoretical analysis of pension indexation because its accurate quantitative effects are far from being sufficiently clarified in the literature, although it is vital for a thoughtful evaluation of pension reforms.
