Limited partnerships (LPs) have received considerable press and policy attention over the past five years, culminating in legal reforms which provide an ability to align LP law more closely to company law. This paper challenges the wisdom of exercising this ability without prior analysis. It draws on historical, conceptual, and empirical methodologies to make three arguments. First, the LP is conceptually different from the company, with LPs being a legal transplant copied from other legal systems, and remaining distinctive: with (mostly) one manager which is meant to have unlimited liability. Secondly, LPs have clear policy aims which are different to those in company law. I use limited liability of an illustration of a policy issue that will be missed by aligning LP law to company law. Thirdly, the LP is overwhelmingly a Scottish vehicle. Recent company law reforms have been argued to be dissonant to Scottish company law, questioning the wisdom of aligning the LP’s regulation to companies.
Existing research shows a significant relationship between state racial minority population, the proportion of racial minority welfare recipients, and state levels of racial resentment with the proposal and adoption of punitive welfare policies. This article contributes to the extant literature by expanding on Ledford’s (2018) 2008–2014 analysis of state drug testing proposals by evaluating state-level racial factors and the diffusion of drug testing proposals from 2009 to 2018. Moreover, the author accounts for the potential influence of drug-related variables on the proposal probability by including variables measuring opioid overdose deaths and illicit drug use estimates. Event history analyses do not find that the size of a state’s Black population or the percentage or proportion of Black welfare recipients significantly affects the proposal rates. However, higher estimates of state-level racial resentment increase the likelihood of proposing drug testing for welfare legislation, supporting Ledford’s conclusion that racial biases matter in the diffusion of these policies. In addition, the author has found evidence that while opioid overdoses are negatively associated with the likelihood of proposal, estimates of illicit drug use have the opposite effect. Finally, analyses suggest that liberalism in state governments actually increases the probability of a proposal.
Margaret Marshall Saunders's best-selling novel Beautiful Joe (1893) has long been indexed as anthropomorphic children's literature. This article examines the novel to illuminate the connection between nineteenth-century literature and animal-focused research, including studies of the science of the mind. My analysis seeks to coalesce what I see as neighboring discourses, both historical and contemporary, in literature and science about what it means to be a thinking, feeling “self.” In doing so, I reveal how Saunders's novel maps out the stakes of this impasse as consequential to literary criticism and the wider culture through its subject matter's entanglement with questions of consciousness, anthropomorphism, and representation.
Turbofan engines are having a growing role in modern aircraft maintenance. Due to this increase, estimation of remaining useful life (RUL) of these engines is an important area of study in the field of reliability and maintenance optimisation. In this work, we propose a hybrid approach that combines deep learning models with similarity-based methods for accurate RUL estimation. For a better comparison, we evaluate four architectures: dropout long short-term memory (LSTM), bidirectional LSTM, convolutional neural network 1D (CNN 1D), and multi-layer LSTM. The FD002 subset of NASA’s Commercial Modular Aero-Propulsion System Simulation dataset is used in the case study. Root mean square error (RMSE) and mean absolute error (MAE) were used for performance metrics. The main output of the study suggests that the dropout LSTM model achieves the best prediction accuracy with an RMSE score of 26.547 and a MAE score of 18.749. It is worth noting that these are achieved despite requiring higher computational resources compared to multi-layer LSTM. Furthermore, all models had difficulties with smaller test trajectory lengths such as 50–100 due to training data imbalance. Overall, the findings highlight the promise of hybrid deep learning and similarity-based approaches for RUL prediction. However, potential advancements such as hyperparameter optimisation and data augmentation still hold potential for further improvements.
Despite their overlapping fin de siècle New Woman communities in London and their correspondence, few scholars have compared the literary works of South African writer Olive Schreiner and Jewish author Amy Levy directly. Reading allegories from Schreiner's first collection, Dreams (1890), in relation to two of Levy's early verse works, “Xantippe” (1881) and Medea (1884), I argue that they both imagine new futures for queer community as an alternative to the oppressive status quo of imperialist England. This paper suggests that Schreiner and Levy, feminist writers with fraught relationships to Englishness, can best be understood as members of a rich community of late Victorian visionaries. When they turn their attention to the forms of allegory and dramatic monologue, Schreiner and Levy are able to explore radical possibilities for gender and community that did not exist in their real lives or their realist fiction. Schreiner and Levy share a deep skepticism about the benefits of marriage, family, and other conventional sources of community, and both offer queer visions of suspended present states or undetermined futures as alternatives.
Early researchers of Yezidis, a small religious minority of the Middle East, often noted with dismay that Yezidis did not say or know prayers. This observation is partially supported by modern-day research, as knowledge of orally transmitted religious texts and their performance is mostly limited to people recognized as religious experts. However, there exists a special sub-genre of prayers which are known and recited by “ordinary” Yezidis. Although they are referred to as “prayers” (dua), these texts do not constitute part of formal religious performances during ceremonial occasions. They could better be described as verbal charms or incantations aimed at healing sickness or warding off evil. This article gives a translation of four previously unrecorded such “prayers”, describes their role in oral tradition, and finally shows how they are now being transformed from performed (and practical) oral religion to written heritage by the younger generation.
A purely elastic linear instability was recently reported for viscoelastic plane Poiseuille flow in the limit of ultra-dilute (solvent to solution viscosity ratio $\beta \gt 0.99$), highly elastic (Weissenberg number $W \sim 1000$) polymer solutions, within the framework of the Oldroyd-B model (Khalid et al., Phys. Rev. Lett., vol. 127, 2021, pp. 134–502). This is the first instance of a purely elastic instability in a strictly rectilinear shearing flow, with the phase speed of the unstable ‘centre mode’ being close to the base-state maximum velocity at the channel centreline. Subsequently, Buza, Page and Kerswell (J. Fluid Mech., vol. 940, 2022, A11) have shown, using the FENE-P model, that the centre-mode instability persists down to moderate elasticities ($W \sim O (100)$), the reduction in threshold evidently due to the finite extensibility of the polymer molecules. In this work, we augment this latter finding and provide a comprehensive account of the effect of finite extensibility on the centre-mode instability in viscoelastic channel flow, using the FENE-P and FENE-CR models, in both the absence and presence of fluid inertia. In both these models, finite extensibility causes a decrease in the polymer relaxation time at high shear rates, and the resulting weakening of elastic stresses would seem to indicate a stabilising effect. The latter trend has been demonstrated by earlier analyses of hoop-stress-driven instabilities in curvilinear flows, and is indeed borne out for the FENE-CR case, where finite extensibility has a largely stabilising influence on the centre-mode instability. In stark contrast, for the FENE-P model, finite extensibility plays a dual role – a stabilising one at lower values of the elasticity number $E$, but, surprisingly, a destabilising one at higher $E$ values. Further, the centre-mode instability is predicted over a significantly larger domain of the $Re$–$E$–$\beta$ parameter space, compared to the Oldroyd-B model, making it more amenable to experimental observations.
The study examines supersonic square jets in a twin nozzle configuration with the aim of identifying and characterising emergent instability modes during overexpanded operation. Unlike screeching rectangular jets that undergo strong fluctuations normal to the wider jet dimension, the equilateral nature of the exit geometry in square nozzles leads to multiple instability states dictated by shock–turbulence interactions and nozzle operating conditions. Furthermore, strong coupling modes between the jets were identified that led to either phase locked or out of phase interactions of the inner shear layers. Results from experimental studies were examined using spatial and temporal decomposition techniques based on spectral methods to identify the resultants from triadic shock–turbulence interactions. The primary instability mode across both operating conditions were driven by optimal interactions while the harmonics were found to be associated with the suboptimal shock–turbulence interactions.
Preliminary evidence suggests that mental imagery may be an important clinical feature in hoarding. Individuals who hoard use objects as receptacles for memories, and experience more frequent, intrusive and distressing images compared with the general community. However, the specific nature of these associations remains poorly understood.
Aims:
We aimed to investigate whether hoarding traits were related to the ability to voluntarily generate imagery in different sensory modalities, and uniquely with the tendency to experience negative intrusive imagery. We also aimed to understand the mechanism by which mental imagery experiences may confer vulnerability to hoarding problems.
Method:
Undergraduates (n=328) completed questionnaires assessing hoarding, beliefs about objects, imagining ability across the senses, and negative intrusive imagery, as well as symptom measures of depression, obsessive-compulsive disorder and post-traumatic stress. We conducted Pearson’s correlations, hierarchical regressions, and mediational analyses.
Results:
Hoarding tendencies were associated with reduced visualising ability, but not with the capacity to deliberately generate imagery in other senses. Hoarding was also uniquely associated with the tendency to experience negative involuntary imagery when controlling for symptoms of depression, obsessive-compulsive disorder, and post-traumatic stress. Object-memory beliefs partially mediated the relationship between hoarding and reduced visualising ability. Object attachment partially mediated the relationship between hoarding and negative intrusive imagery.
Conclusions:
Results suggest that visualisation difficulties may promote a reliance on objects to facilitate recall, and experiencing negative intrusive imagery may strengthen object attachment. Findings may inform imagery-based conceptualisations and treatments of hoarding problems, such as imagery training or modification interventions.
While most higher taxa in the Hemiuroidea exhibit remarkable diversity and thrive worldwide in marine ecosystems, a few groups have successfully radiated into freshwater environments. Among them, species of Thometrema are well known from freshwater and brackish fishes in the New World. In this study, specimens of Thometrema from a single specimen of the endangered pimelodid catfish Steindachneridion scriptum in the Upper Paraná River basin, State of São Paulo, Brazil, were subjected to morphological, ultrastructural (first scanning electron microscopy data for the genus) and molecular analyses. Newly obtained sequences of the partial large subunit nuclear ribosomal RNA (28S rDNA) and partial mitochondrial cytochrome c oxidase subunit I (COI mtDNA) provided strong evidence supporting the identification of the specimens as T. patagonicum, a trematode previously known only from endemic percichthyid fishes (Percichthyidae) in the Argentinian Patagonia. This unexpected finding, along with critical morphological evaluation of new and deposited material, led us to propose T. overstreeti and T. bonariense as junior synonyms of T. patagonicum. Moreover, we reassessed certain morphological features, revealed new potential distinguishing characters (papillae) and raised doubts about the taxonomic value of commonly used features for species differentiation (e.g., vitellarium masses). To overcome taxonomic problems in Thometrema due to the paucity of morphological features to clearly set species boundaries, new descriptions could leverage integrative approaches, as employed here, to establish robust species hypotheses and ultimately unravel the actual species composition in the Americas.
This study aimed to assess the perception of disaster risk and the level of earthquake awareness among students enrolled in the Department of Nursing at Artvin Çoruh University, Faculty of Health Sciences. The study sample comprised 274 students enrolled in the Department of Nursing at Artvin Çoruh University, Faculty of Health Sciences. The data were gathered utilizing the Sociodemographic Characteristics Form, Disaster Risk Perception Scale, and Sustainable Earthquake Awareness Scale. The data was obtained using the SPSS 24.0 program and analyzed using t tests, One-way ANOVA, and Pearson correlation analyses. The study’s findings indicate that most students have yet to undergo disaster training, yet most are interested in such training. Furthermore, it was ascertained that most students had not encountered any calamity. However, they wanted to participate actively and voluntarily in disaster scenarios. A statistically significant difference was observed between the students’ class and the average total scores of disaster risk perception scale and sustainable earthquake awareness scale. Courses on disaster management should be added to nursing education curricula. In order to provide disaster risk perception and sustainable earthquake awareness to nursing students, they need to take part in different activities in the field of disaster management.
Lingual seizures are rare hyperkinetic tongue movements with significant clinical implications due to their epileptogenic origin. Despite their diagnostic value, these seizures are often underrecognized, particularly when electroencephalographic (EEG) findings are inconclusive. This study aims to characterize their clinical features, EEG patterns, imaging findings and underlying causes, emphasizing the need for increased awareness and improved diagnosis.
Methods:
A retrospective review identified patients with isolated lingual seizures or those with additional motor involvement. Data on demographics, seizure characteristics, EEG findings, imaging results and underlying causes were collected and analyzed. Seizures were classified based on the International League Against Epilepsy (ILAE) 2017 framework to refine their clinical and diagnostic profiles.
Results:
Thirteen patients were identified: 11 with focal-aware and 1 with focal-unaware seizures. Seven had epilepsia partialis continua, and five experienced frequent seizures. Seizure involvement was limited to the tongue in four cases, extended to cranial muscles in seven and affected the tongue, cranial and extremity muscles in two. Significant ictal EEG findings were noted in only three patients with extensive motor involvement. However, nine patients had acute cerebral lesions, associated with glial tumors, encephalitis, chronic gliosis or cortical hemorrhage.
Conclusions:
This study provides a detailed characterization of lingual seizures, highlighting their clinical, electrophysiological and imaging features. Given their rarity and underdiagnosis, our findings offer valuable guidance for clinicians, underscoring the importance of improved recognition and diagnostic strategies for this distinct seizure type.
We report the case of a 25 kg male with aortic isthmus atresia and small femoral arterial access. A BeGraft covered stent was percutaneously implanted after perforating the atretic segment. This case demonstrates the feasibility and safety of transcatheter treatment using the Bentley stent, which enables smaller femoral access compared to other balloon-expandable stent platforms.
Young adults with a psychotic disorder often experience difficulties in social functioning. We developed a modular virtual reality treatment to improve social activities and participation by targeting common causes of social functioning difficulties in patients with a psychotic disorder (VR-SOAP). This paper details the development of this intervention, encompassing a piloting phase.
Method:
Using an iterative Scrum method with software engineers, clinicians, researchers, and individuals with lived experience of psychosis, we developed a treatment protocol along with a software prototype. Subsequently five patients with a psychotic disorder, aged 18–40, and three therapists, piloted VR-SOAP. Feasibility was assessed by means of interviews and session forms. Acceptability was evaluated along the seven domains of the Theoretical Framework of Acceptability (i.e. affective attitude, burden, ethicality, intervention coherence, opportunity costs, self-efficacy, and perceived effectiveness).
Results:
The final protocol consisted of the following modules and targets: 1. Motivation and Pleasure (negative symptoms); 2. Understanding Others (social cognition); 3. Safety and Trust (paranoid ideations and social anxiety); 4. Self-Image (self-esteem and self-stigma); 5. Communication (communication and interaction skills). Modules were piloted by the participating patients and therapists. The modules proved feasible and showed a high degree of acceptability on all seven domains of the acceptability framework.
Conclusion:
The modular VR-SOAP treatment protocol and prototype was acceptable and feasible for therapists and patients. The primary recommendation for enhancement underscores the need for flexibility regarding the number of sessions and the content.
Key learning aims
(1) Understanding the development and structure of a novel modular CBT treatment in VR.
(2) Learning to use specific VR modules to target negative symptoms, social cognition, paranoid ideations, social anxiety, self-esteem, and communication skills.
(3) Gaining insights into the feasibility and acceptability assessments of a novel modular CBT treatment in VR.
The studies of descriptive political representation demonstrate that the share of women amongst local elected officials increases, but mayors are still predominantly men. This paper contributes to the literature on the link between the descriptive and substantive representation of women at the local level. It investigates the influence of mayors’ gender on the development of local childcare policies in Poland. We employ quasi-experimental research schemes (difference-in-differences and generalised synthetic control) to study changes in childcare provision and public spending on nurseries and kindergartens. We merged electoral data (changes on the mayoral position) and registry data on local budget expenditures and service availability covering a period of more than 16 years. We do not find any systematic causal link, suggested by the extant literature on substantive representation, between the election of a female mayor and the expansion of childcare services.
