Spain’s greatest modern philosopher, José Ortega y Gasset (1883-1955), wrote about many aspects of education including its aims; the education of children, nations, and elites; types of pedagogy; the reform of the university; and the challenges facing educators in an era of “triumphant plebeianism.” The article examines all aspects of Ortega’s educational thought, with a particular focus on his ideas about elites and their education, drawing on writings unavailable in English, including texts not published during his lifetime. At the heart of his writing is a vision of the qualities needed to enable individuals to make what he called a “project” out of their lives along with a powerful advocacy of the non-utilitarian and Socratic pedagogies that would help achieve that vision. The article looks at the balance of radical and conservative elements within Ortega’s educational thought and its relation to earlier “progressive” thinkers, and concludes with an evaluation of his legacy.
The aim of this study was to investigate the association of the rs43389227, rs43390124 and rs482883241 single-nucleotide polymorphisms (SNPs) of the bovine calcium channel, voltage-dependent, alpha-2/delta subunit 1 (CACNA2D1) gene with milk yield and quality traits in Holstein cattle. For this purpose, 166 Holstein dairy cows were genotyped for these three SNPs. Correlation analyses showed that the rs43389227 SNP was associated with 305-day milk yield (P < 0.05). Besides, rs43390124 SNP was found to be associated not only with 305-day milk yield but also with milk fat, milk quality traits, somatic cell score, electrical conductivity and pH (P < 0.05). The results of this study suggest that the rs43389227 and rs43390124 SNPs could be used in breeding for the improvement of milk yield and milk quality in cattle. Furthermore, based on its association with mastitis related traits, the rs43390124 SNP was considered as a potential indicator of mastitis susceptibility.
The city was hit by a flood on July 5, 2022. Afterwards, the mayor of Belgrade declared that no one should be blamed because we cannot influence God’s will. Objective is examination of the relationship between such a laissez-faire approach to Disaster Risk Reduction (DRR) from the city government, and some groups from hill areas (historically not flooded), who were flooded and have started to develop DRR approaches to adequately respond to the next possible flood.
Methods
Participant observation site work is in progress and includes 32 households in the residential hill area of Belgrade that experienced its first rain floods from 2019 to 2023. DRR is represented through self-installed special devices on the city sewage network. The data collection and analysis included narrative analysis and sociological analysis of photographs. All data was first anonymized as some practices were viewed as legitimate but not always legal.
Results
During the relevant three years, the number of non-flooded homes increased proportionally with increasing self-installation of special devices on their city sewage system
Conclusions
Groups left without official DRR policies can develop resilience through individual actions in communal infrastructure and find ways to resist natural hazards and government laissez-faire DRR.
This article explores aspects of the organization of refugee education in imperial Austria during the First World War. Authorities in charge of refugees’ control and their eventual assistance interpreted access to education in two ways. First, it was an avenue of relief through schooling, aimed to counter the effects of uprootedness and, thus, safeguard some continuity in refugee children’s lives. Second, it was a way to ensure the making of productive and loyal citizens. In this context, this article looks at various policies regarding organization of schooling for displaced children. Moreover, it analyzes the ways language entered the realm of the refugee-focused classroom. Officials used schooling in refugee students’ vernacular to relieve the effects of their displacement and to reinforce ethnonational classifications of imperial subjects. At the same time, education through refugee children’s growing exposure to German language courses became a measure of a gradual inculcation of an imperial consciousness. Furthermore, it was a civilizing dimension of displacement management and, in this way, it became an avenue to consolidate a war-feeble state.
Aplectana hylambatis (Baylis, 1927) is a widespread nematode in South America that infects different species of anurans from different families. Although the morphology of this species shows intraspecific variations and is well studied, A. hylambatis does not have genetic characterisation. Therefore, the present study aimed to provide the first genetic characterisation of this parasite, based on 18S and 28S rDNA sequences, as well as to evaluate its phylogenetic position in the family Cosmocercidae. The present specimens showed no major morphological variations and were assigned to A. hylambatis mainly based on the shape of spicules and the presence of mamelon-like structures slightly anterior to the vulva. The genetic characterisation confirmed the close relationship between A. hylambatis and other cosmocercids, and the 28S sequences were more informative for phylogenetic reconstruction, especially for those relationships at higher and intermediate levels. Aplectana hylmabatis was in a basal position within a clade formed by other congeners and species of Cosmocerca. The geographic origin may have influence in the divergence process of Aplectana spp. and genus was non-monophyletic and closely related to Cosmocerca, similar to previous findings. The present results will be useful for future studies on the phylogeny of Cosmocercidae, since several genera and species in this family still lack genetic characterisation. Furthermore, the 28S sequences can be useful in genetic studies of A. hylambatis populations, since this species appears to have phenotypic variations.
Reintroduction includes the captive propagation and movement of extirpated animals or plants into areas of historical and native distribution. Many biotic or abiotic factors can affect a founder population when small numbers are released into unfamiliar novel environments, particularly at the early stage of reintroduction. The inclusion of behavioural and ecological components plays a crucial role in the decision-making process of endangered species conservation efforts such as reintroduction. Since the resident population of Oriental Storks Ciconia boyciana was locally extirpated in South Korea in 1971, its founders have been established through reintroduction since 2015. The aim of this study was to investigate the demography, habitat use, and movement patterns of stork founders using the first two-year demographic and tracking data. Stork founders maintained their population size, which slightly increased in the long term. The patterns of habitat use and movement depended on rice paddy fields for foraging and breeding along with mixed effects of breeding status and season. Considering ecological and life history-related perspectives, we also discuss the potential adaptiveness of founder Oriental Storks as a resident population in a novel environment in South Korea.
We present an experimental investigation aimed at understanding the effects of surface roughness on the time-mean drag coefficient ($\bar {C}_{D}$) of finite-span cylinders ($\text {span/diameter} = \text {aspect ratio}$, $0.51 \le AR \le 6.02$) freely rolling without slip on an inclined plane. While lubrication theory predicts an infinite drag force for ideally smooth cylinders in contact with a smooth surface, experiments yield finite drag coefficients. We propose that surface roughness introduces an effective gap ($G_{eff}$) resulting in a finite drag force while allowing physical contact between the cylinder and the plane. This study combines measurements of surface roughness for both the cylinder and the plane panel to determine a total relative roughness ($\xi$) that can effectively describe $G_{eff}$ at the point of contact. It is observed that the measured $\bar {C}_{D}$ increases as $\xi$ decreases, aligning with predictions of lubrication theory. Furthermore, the measured $\bar {C}_{D}$ approximately matches combined analytical and numerical predictions for a smooth cylinder and plane when the imposed gap is approximately equal to the mean peak roughness ($R_p$) for rough cylinders, and one standard deviation peak roughness ($R_{p, 1\sigma }$) for relatively smooth cylinders. As the time-mean Reynolds number ($\overline {Re}$) increases, the influence of surface roughness on $\bar {C}_{D}$ decreases, indicating that wake drag becomes dominant at higher $\overline {Re}$. The cylinder aspect ratio ($AR$) is found to have only a minor effect on $\bar {C}_{D}$. Flow visualisations are also conducted to identify critical flow transitions and these are compared with visualisations previously obtained numerically. Variations in $\xi$ have little effect on the cylinder wake. Instead, $AR$ was observed to have a more pronounced effect on the flow structures observed. The Strouhal number ($St$) associated with the cylinder wake shedding was observed to increase with $\overline {Re}$, while demonstrating little dependence on $AR$.
This study aims to assess the public healthcare system by implementing a scorecard in Hatay and Kahramanmaras provinces in Türkiye after the Kahmaranmaras earthquake.
Method
The methodology employing in this study, action research, informs the active interaction between participants who have been involved in disaster risk reduction in the variety of capacities, such as affected local government, emergency medicine department, nursing and care association.
Results
The scorecard application was carried out with 18 participants in Maraş and 22 in Hatay. The scorecard application shows that the items with the lowest scores in Hatay were related to the resilience of public health infrastructure and key health facilities, and the fulfilment of society’s role in disasters. In Maraş, on the other hand, coping with patient surge in disaster, fulfilment of society’s role in disasters, and mental health services in the context of disasters.
Conclusions
With the participation in scorecard workshop, communications between these stakeholders for community public healthcare system can discuss the best way to prepare and collaborate to promote further community disaster risk reduction planning during post-disaster recovery phase.
We investigate effect of porous insert located upstream of the separation edge of a backward-facing step (BFS) in early transitional regime as a function of Reynolds number. This is an example of hydrodynamic system that is a combination of separated shear flow with large amplification potential and porous materials known for efficient flow destabilisation. Spectral analysis reveals that dynamics of BFS is dominated by spectral modes that remain globally coherent along the streamwise direction. We detect two branches of characteristic frequencies in the flow and with Hilbert transform we characterise their spatial support. For low Reynolds numbers, the dynamics of the flow is dominated by lower frequency, whereas for sufficiently large Reynolds numbers cross-over to higher frequencies is observed. Increasing permeability of the porous insert results in decrease in Reynolds number value, at which frequency cross-over occurs. By comparing normalised frequencies on each branch with local stability analysis, we attribute Kelvin–Helmholtz and Tollmien–Schlichting instabilities to upper and lower frequency branches, respectively. Finally, our results show that porous inserts enhance Kelvin–Helmholtz instability and promote transition to oscillator-type dynamics. Specifically, the amplitude of vortical (BFS) structures associated with higher-frequency branch follows Landau model prediction for all investigated porous inserts.
