The Taita Falcon Falco fasciinucha is known to occur and breed at only a few locations in eastern and southern Africa and is currently listed as globally “Vulnerable” and “Critically Endangered” in South Africa. An accurate estimation of its conservation status is however hampered by a lack of data and understanding of the species’ habitat requirements and competitive interactions with congeners. Our aim was to address some of these knowledge gaps. We conducted cliff-nesting raptor surveys across a substantial area of the Mpumalanga/Limpopo escarpment in north-eastern South Africa and modelled habitat suitability for nesting Taita Falcons in relation to the proximity of conspecifics and a community of five other sympatric cliff-nesting raptor species, and in relation to a suite of biotic and abiotic environmental variables. Results suggested the location of Taita Falcon nest sites was negatively associated with distance to the nearest pair of conspecifics and the nearest pair of Lanner Falcons Falco biarmicus, and positively associated with tracts of intact, unfragmented forest and woodland around the base of the cliffs. Our results indicated that Taita Falcon and Lanner Falcon appeared to be responding in opposite ways to a directional change in environmental conditions. This response appeared to be detrimental to Taita Falcon and beneficial to Lanner Falcon. Furthermore, the degradation and destruction of Afrotropical woodland and forest is a documented and ongoing reality, both locally and across much of the Taita Falcon’s global distribution. We argue that our findings are sufficient to justify uplisting Taita Falcon to globally “Endangered”.
Trichinellosis is a worldwide zoonotic disease affecting a wide range of mammals, including humans. It has intestinal and muscular phases. The current work was done to experimentally evaluate the efficacy of zinc oxide nanoparticles (ZnO NPs) and their combination with albendazole on intestinal and muscular stages of Trichinella spiralis (T. spiralis) infection. We had five main groups of mice: Group 1, non-infected control; Group 2, infected control; Group 3, infected and treated with albendazole; Group 4, infected and treated with ZnO NPs; and Group 5, infected and treated with albendazole and ZnO NPs. Each group was divided into two subgroups (A for the intestinal phase and B for the muscular phase). Drug effects were evaluated by parasitological, histopathological, and biochemical studies, including oxidant/antioxidant analysis and vascular endothelial growth factor (VEGF) gene expression in muscle tissue by quantitative real-time PCR. ZnO NPs resulted in a significant reduction of both intestinal and muscular phases of T. spiralis. Their combination with albendazole resulted in the complete eradication of adult worms and the maximum reduction of larval deposition in muscle tissue. Additionally, the treatment showed improvement in T. spiralis-induced pathological changes and oxidative stress status. Moreover, a significant decrease in VEGF gene expression was detected in the treated groups when compared with the infected control. In conclusion, ZnO NPs presented an antihelminthic effect against both adult and larval stages of T. spiralis. In addition, it enhanced antioxidant status and suppressed angiogenesis in muscle.
Compound surfaces, consisting of periodic arrays of solid patches and free surfaces, exhibit hydrodynamic slipperiness which is quantified by their slip length. The limit of small solid fractions, where the slip length diverges, is of fundamental interest. This paper addresses longitudinal liquid flows over a periodic array of grooves which are partially invaded by the liquid. Assuming that the slats separating the grooves are infinitely thin, the solid fraction $\epsilon$ is set by the invasion depth. Inspired by the singular small-solid-fraction limit for non-invaded grooves (Schnitzer, Phys. Rev. Fluids, vol. 1, 2016, 052101R), we consider the idealised geometry of $90^{\circ }$ protrusion angles, where an integral force balance in the limit $\epsilon \to 0$ implies a slip length that scales as $\epsilon ^{-1}$. The problem exhibits a nested structure, where the liquid domain is conceptually decomposed into four distinct regions: a unit-cell region on the scale of the period, where the wetted portion of the slat appears as a point singularity; two regions on the scale of the wetted slat, where the flow essentially varies in one dimension; and a transition region about the tip of the slat. Analysing these regions using matched asymptotic expansions and conformal mappings yields the ratio of slip length to semi-period as $2\epsilon ^{-1} - (10/{\rm \pi} )\ln 2 + \cdots$.
A core tenet of representation is that individuals should expect government to actively protect their human security. In the issue area of domestic violence in the United States, government largely fails to do this for women, who comprise three-quarters of all victims of domestic violence. Nowhere is this more apparent than for Native American women living on tribal lands. In terms of lifetime physical violence, nearly 52% of Native American women will be physically abused compared to 30.5% of white women, 41.2% of African American women, and 29.7% of Hispanic women (Crepelle 2020; Institute for Women’s Policy Research 2023). One of the main obstacles to keeping Native American women safer is that tribal nations have been functionally prohibited from prosecuting non-Native offenders of violence against Native Americans on their lands. Non-Native offenders comprise the bulk of domestic violence abusers in these communities. To address this inequity, the 2013 Violence Against Women Act (VAWA) created Special Domestic Violence Criminal Jurisdictions (SDVCJs). Through an application process, federally recognized tribal nations can create these jurisdictions to provide justice for the many women who are victims of domestic violence at the hands of non-Native persons. In this article we explore which tribal nations created these jurisdictions using an original dataset of the 354 tribal nations that were eligible to adopt an SDVCJ following the 2013 VAWA reauthorization. As of 2022, 31 tribal nations have adopted SDVCJs across 13 states, which have led to 74 domestic violence convictions. In this article, we explain adoption of these courts as a function of population, tribal nation fiscal capacity, federal grant support, and having an existing self-governance compact with the Bureau of Indian Affairs.
The present study examines how different lifelong employment patterns are related to social relationships in old age, and whether there are gender differences in the impact of lifelong employment patterns.
Designs and participants:
The study was based on data collected among European adults as part of the Health, Aging and Retirement Survey in Europe (SHARE) and focuses on retired adults.
Measurements:
The study combines data on social relationships, collected in 2015, with retrospective data on employment history (number of jobs and years of employment) collected in 2017.
Results:
The findings show that adults who worked in more jobs had overall better structural characteristics of their later life networks – they had larger social networks and were more likely to include children and friends within those networks but less likely to include their spouse. On the other hand, working in more jobs was related to less emotional closeness with the network. These results varied between men and women; women who were involved in the labor market over their life had larger social networks and tended to include friends as confidants. Among men, working for more years was related to higher emotional closeness with the social network.
Conclusions:
The study may indicate a gendered pattern of social advantages and disadvantages to involvement in the labor market over the work course. Practitioners should consider the lifelong employment of adults to identify those who might be at risk of social isolation.
This article examines the presence and influence of the work of Swiss psychiatrist Ludwig Binswanger and existential analysis (Daseinsanalyse) in Spanish psychiatry in the central decades of the 20th century. First, and drawing on various printed and archival sources, it reconstructs the important personal and professional ties that Binswanger maintained with numerous Spanish colleagues and describes the notable dissemination of his work in Spain through bibliographical reviews, scientific events, academic reports, university lectures and translations. Next, it reviews the incorporation of the postulates of existential analysis into the discourse of Spanish psychiatrists and assesses their most elaborate and original contributions to the foundations of ‘anthropological–existential’ psychiatry or the ‘existential–analytical’ interpretation of certain disorders or clinical conditions. And, finally, it tries to clarify the assessment according to which the (inevitable) instrumentalisation of existential analysis in the context of Franco’s Spain first compromised the critical recognition of its true possibilities (and limits) and later contributed to the discrediting of psychopathological research among Spanish psychiatrists.
Patients with unbalanced common atrioventricular canal can be difficult to manage. Surgical planning often depends on pre-operative echocardiographic measurements. We aimed to determine the added utility of cardiac MRI in predicting successful biventricular repair in common atrioventricular canal.
Methods:
We conducted a retrospective cohort study of children with common atrioventricular canal who underwent MRI prior to repair. Associations between MRI and echocardiographic measures and surgical outcome were tested using logistic regression, and models were compared using area under the receiver operator characteristic curve.
Results:
We included 28 patients (median age at MRI: 5.2 months). The optimal MRI model included the novel end-diastolic volume index (using the ratio of left ventricular end-diastolic volume to total end-diastolic volume) and the left ventricle–right ventricle angle in diastole (area under the curve 0.83, p = 0.041). End-diastolic volume index ≤ 0.18 and left ventricle–right ventricle angle in diastole ≤ 72° yield a sensitivity of 83% and specificity of 81% for successful biventricular repair. The optimal multimodality model included the end-diastolic volume index and the echocardiographic atrioventricular valve index with an area under the curve of 0.87 (p = 0.026).
Conclusions:
Cardiac MRI can successfully predict successful biventricular repair in patients with unbalanced common atrioventricular canal utilising the end-diastolic volume index alone or in combination with the MRI left ventricle–right ventricle angle in diastole or the echocardiographic atrioventricular valve index. A prospective cardiac MRI study is warranted to better define the multimodality characteristic predictive of successful biventricular surgery.
Scholars have long contested James Madison's position on religious liberty. Madison believed in governmental noncognizance of religion. The dominant view, voiced by Vincent Muñoz, interprets that to mean that government should take no notice of religion either to target it or to allow religious objectors exemptions from neutral and generally applicable laws. While there is much to commend Muñoz's view, it fails to accurately convey Madison's position. Noncognizance, for Madison, meant not that government should not notice religion, but that it should assume no authority over it. Consequently, Madison believed government should not interfere with religious duties unless to achieve important ends via carefully tailored policies.
This article explores the potential use of ethnomusicology in the development of entrepreneurialism amongst Western classical music students studying at UK music colleges. It is argued that both ‘doing’ and ‘reading’ ethnomusicology can encourage students to explore the diverse uses and meanings attached to Western classical music in varied social and geographic contexts. The knowledge garnered through ethnomusicology can then be applied in creative, informed and situational ways by students in the development of entrepreneurial strategies. As a by-product, it is suggested that ethnomusicology can be used to reframe entrepreneurialism as a musical, relational and interactive process.
This is the first simultaneous morphological and barcoding characterization with the cytochrome c oxidase subunit I (COI) of the bramble shark Echinorhinus from the coast of Oman. The morphology of the specimen was consistent with previous records of Echinorhinus from the Gulf of Oman and the Arabian Sea (Northwestern Indian Ocean). However, the new COI haplotype clustered together with homologous sequences of specimens from India. The specimen from Oman distinguished morphologically and genetically from an E. brucus from the Western Atlantic Ocean on the shape and size of the dermal denticles, the proportions of twelve morphometric measurements (differences ⩾3%) and the genetic p-distance = 3.8% of the COI fragment. The haplotype reported here increases the genetic diversity in genus Echinorhinus in the Northwest Indian Ocean, demonstrates conspecificity between specimens from Oman and Echinorhinus cf. E. brucus distributed in India and extends its range of distribution. The limited morphological and molecular data available constrained assigning our specimen to other than Echinorhinus cf. E. brucus (Bonnaterrez, 1788). Our findings highlight the urgent need of morphological review, redescription and the assignment of a neotype in order to guarantee accurate species identification and thus effective conservation measures for these deep-sea sharks. The existence of a third living species in the genus is briefly discussed.
The 1930s American Dust Bowl created archetypal “Dust Bowl migrants,” refugees from environmental collapse. I examine this archetype, comparing migration from more-eroded and less-eroded counties to distinguish Dust Bowl migrants from other migrants. Dust Bowl migrants were “negatively selected,” in years of education, compared to other migrants who were “positively selected.” Dust Bowl migrants had lower incomes than natives in their destinations, which is reflected in popular impressions. I estimate strikingly modest impacts of the Dust Bowl on average wage incomes in 1939, however, which contrasts with the Dust Bowl’s large and enduring impacts on agricultural land.
This paper examines the patterns of technology transfer from Britain to France during the early phases of industrializing using a dataset comprising all patents granted in France in the period 1791–1844. Exploiting the peculiarities of French legislation, we construct an array of patent quality indicators and investigate their determinants. We find that patents filed by British inventors or French inventors with personal connections to British inventors were of relatively higher quality. Overall, our results show that the French innovation system was capable of attracting and effectively absorbing key technologies from Britain.
In February and March 1953, a WHO Visiting Team of Medical Scientists worked in India, collaborating with local medical students and professionals. This article studies the complexities of early postcolonial international health work and the relations between the young WHO and the newly independent countries, from the position of the team’s vice chairman, Norwegian doctor Karl Evang. While the WHO aimed to create dialogue and interaction, also learning from the host country, the article finds that an equal exchange of views between visitors and hosts was not achieved. The topic pertains to discussions on power and influence in international organisations and governance, development and health work, within a South Asian setting. Studying intellectual exchanges between Evang and his Indian interlocutors sheds light on India’s role as both receptive and generative site of ideas and political practice, contributing to broader debates on the appropriation, refashioning and application of political ideas in independent India. Also, at a time of new directions in international health, and considering Evang’s social medicine conviction, an additional question concerns the role of social medicine. The article underlines the existence of multiple, parallel tracks in international health work, and argues the need to portray international health as a complex mosaic, rather than a step-by-step development. The case has relevance as historians endeavour to make international and global history more diverse, as through Evang we capture parts of a broader international involvement of people and nation states in the WHO and its work in the early post-war period.
