Broad and complex ideas about sustainability can be communicated through the Arts. Australian curriculum documents support the integration of Arts education with education for sustainability. Responding to artworks as a viewer is a key aspect of Arts education in Australian schools. Chris Jordan is a US artist whose online media galleries communicate ideas about environmental and social justice themes. This paper reports interview data from a larger project exploring children’s responses to Chris Jordan’s artworks. Conversations were held with 28 children aged between 4 and 12 as they navigated Jordan’s website to explore the images they encountered. Data relating to SDG14: Life below water were selected for the specific focus of this paper. Thematic analysis of the data revealed five themes: connections to prior experience and knowledge, links with local contexts and places, emotional engagement with the images, solutions and action-taking and ideas related to post-humanism and the human-nature binary. These findings endorse the power of Arts-based experiences for enhancing education for sustainability in primary schools and early childhood contexts.
We consider steady surface waves in an infinitely deep two-dimensional ideal fluid with potential flow, focusing on high-amplitude waves near the steepest wave with a 120$^{\circ }$ corner at the crest. The stability of these solutions with respect to coperiodic and subharmonic perturbations is studied, using new matrix-free numerical methods. We provide evidence for a plethora of conjectures on the nature of the instabilities as the steepest wave is approached, especially with regards to the self-similar recurrence of the stability spectrum near the origin of the spectral plane.
The concept of heightened human rights due diligence (hHRDD) is often used to address corporate responsibilities in situations of armed conflict. For companies in these contexts, the first step is to assess whether their activities impact the conflict and its dynamics, and, as a result, whether they are involved in conflict-related human rights abuses. However, companies often find that they have no impact on the conflict. Should companies in these scenarios just focus on regular human rights due diligence (HRDD)? This piece aims to illustrate, based on the example of Ukraine, the human rights challenges that emerge during a war which companies with no influence on the conflict still face and to respond to the question of whether in such situations companies should still engage in hHRDD or continue to conduct HRDD as usual.
Rapid, unpredictable ecological changes and the resulting instability that are characteristic of the Anthropocene call for a re-examination of the role of law in governing interactions between humans and ecosystems and facilitating adaptation to ecological change. The scope and scale of environmental change we are experiencing seem to call for a regulatory approach, namely forms of law that are designed to pursue well-defined material objectives, often through instruction rules designed to guide behavior to line up with those objectives. Such forms of law have a crucial role to play. However, the negligence principle at the heart of civil liability law is also capable of absorbing and circulating information about environmental risk and means of addressing it, and of translating that information from empirical to normative terms. The grounding of negligence in domestic civil liability law could be a serious obstacle to its effectiveness given the global, Earth system-wide nature of environmental degradation. However, the negligence principle increasingly operates through networks that traverse jurisdictional boundaries, as well as the boundaries between social systems. I propose such a network approach to analyze interactions between the negligence principle and corporate due diligence obligations embedded in domestic legislation and international texts such as the United Nations Guiding Principles on Business and Human Rights (UNGPs). One important result would be the imposition of expanded epistemic obligations on firms, which would in turn require their serious engagement with domestic, international, and transnational environmental and sustainability norms.
Cognitive reserve (CR) is typically operationalized as episodic memory residualized on brain health indices. The dimensionality of more generalized models of CR has rarely been examined.
Methods:
In a sample of N = 113 dementia-free older adults (ages 62–86 years at MRI scan; 58.4% women), the domain-specific representation of general cognition (COG) before vs. after residualization on brain indices (brain volume loss, cerebral blood flow, white matter hyperintensities) was compared (i.e., COG vs. CR). COG and CR were assessed by 15 tasks spanning five domains: processing speed, verbal memory, visuospatial memory, fluid reasoning, and vocabulary. Measurement invariance and item-construct representation were tested in a series of structural factor analyses. COG and CR were then examined in relation to 22 risk and protective factors and dementia status at time of death.
Results:
Item-factor loadings differed such that CR more strongly emphasized fluid reasoning. More years of education, higher occupational class, more hobbies/interests, and fewer difficulties with personal mobility similarly predicted better COG and CR. Only the sub-domain of visuospatial memory (both before and after residualization) was associated with conversion to dementia by end-of-life (r = −.30; p = .01).
Conclusions:
Results provide tentative support for the role of fluid reasoning (intelligence) as a potential compensatory factor for age- and/or neuropathology-related reductions in processing speed and memory. Intellectually stimulating work, efforts to preserve personal mobility, and a diversity of hobbies and interests may attenuate age- and/or pathology-related reductions in cognitive functioning prior to dementia onset.
Early modern London was multilingual, and early modern urban life was shaped by linguistic diversity. This article draws on the multilingual archives of Elizabethan London's ‘stranger churches’ – Protestant congregations which catered to the needs of French-, Dutch- and Italian-speaking migrants (among others) – to explore how linguistic diversity shaped social relations. These sources offer insights into the everyday multilingualism of the early modern city. They demonstrate London's migrant communities’ intense interest in what people said and why, and show how different languages and their speakers interacted on the streets and in the spaces of later sixteenth-century London. By charting how linguistic diversity was part of the lives of ordinary Londoners in this period, including close examination of incidents of multilingual insult, slander, and conflict, this article argues that the civic and religious authorities relied on the stranger churches’ abilities to carry out surveillance of speech in languages other than English, and that urban social relations and urban spaces were shaped by multilingualism. It ends by arguing that linguistic diversity played an essential but understudied role in the social history of early modern cities.
Normal aging often leads to cognitive decline, and oldest old people, over 80 years old, have a 15% risk of developing neurodegenerative diseases. Therefore, it is important to have appropriate tools to assess cognitive function in old age. The study aimed to provide new norms for neuropsychological tests used to evaluate the cognitive abilities in people aged 80 years and older in France, focusing on the impact of education and gender differences.
Method:
107 healthy participants with an average age of 85.2 years, with no neurological history or major cognitive deficits were included. A comprehensive neuropsychological assessment was performed, covering several cognitive functions such as memory, visuospatial abilities, executive functions, attention, processing speed, and praxis.
Results:
Individuals with lower levels of education performed poorly on some tests and took longer to complete. Gender differences were observed, with women outperforming men in verbal episodic memory, while men showed better performance in visuoconstructive tasks. The participants showed lower performance in verbal episodic memory compared to norms established in previous French studies. In relation to executive functions, participants were slower to perform complex tasks than participants in previous studies.
Conclusion:
This study provides cognitive norms specifically adapted to the oldest old population, which differ from established norms for younger aging adults. It highlights the importance of including these norms in future clinical and scientific investigations. The findings underscore the importance of education on cognitive abilities and emphasize the need to consider gender differences when assessing cognitive functions in aging populations.
This work describes a hyperbolic model for cell-cell repulsion with population dynamics. We consider the pressure produced by a population of cells to describe their motion. We assume that cells try to avoid crowded areas and prefer locally empty spaces far away from the carrying capacity. Here, our main goal is to prove the existence of travelling waves with continuous profiles. This article complements our previous results about sharp travelling waves. We conclude the paper with numerical simulations of the PDE problem, illustrating such a result. An application to wound healing also illustrates the importance of travelling waves with a continuous and discontinuous profile.
The background potential energy (BPE) is the only reservoir that double diffusive instabilities can tap their energy from when developing from an unforced motionless state with no available potential energy (APE). Recently, Middleton and Taylor linked the extraction of BPE into APE to the sign of the diapycnal component of the buoyancy flux, but their criterion can predict only diffusive convection instability, not salt finger instability. Here, we show that the problem can be corrected if the sign of the APE dissipation rate is used instead, making it emerge as the most fundamental criterion for double diffusive instabilities. A theory for the APE dissipation rate for a two-component fluid relative to its single-component counterpart is developed as a function of three parameters: the diffusivity ratio, the density ratio, and a spiciness parameter. The theory correctly predicts the occurrence of both salt finger and diffusive convection instabilities in the laminar unforced regime, while more generally predicting that the APE dissipation rate for a two-component fluid can be enhanced, suppressed, or even have the opposite sign compared to that for a single-component fluid, with important implications for the study of ocean mixing. Because negative APE dissipation can also occur in stably stratified single-component and doubly stable two-component stratified fluids, we speculate that only the thermodynamic theory of exergy can explain its physics; however, this necessitates accepting that APE dissipation is a conversion between APE and the internal energy component of BPE, in contrast to prevailing assumptions.
Let G be a connected semisimple real algebraic group. For a Zariski dense Anosov subgroup $\Gamma <G$ with respect to a parabolic subgroup $P_\theta $, we prove that any $\Gamma $-Patterson–Sullivan measure charges no mass on any proper subvariety of $G/P_\theta $. More generally, we prove that for a Zariski dense $\theta $-transverse subgroup $\Gamma <G$, any $(\Gamma , \psi )$-Patterson–Sullivan measure charges no mass on any proper subvariety of $G/P_\theta $, provided the $\psi $-Poincaré series of $\Gamma $ diverges at its abscissa of convergence. In particular, our result also applies to relatively Anosov subgroups.
Compassion is essential in palliative care; however, there is a lack of evidence of the association between this construct and patients’ dignity-related distress. The present study aimed to investigate the association between end-of-life cancer patients’ sense of dignity, the level of compassion of the healthcare professionals (HCPs) noticed and perceived by the patients, and levels of compassion that HCPs felt they had toward patients, investigating through specific attitudes and behaviors. Furthermore, the relationship between compassion and patients’ physical and psychological symptoms, such as levels of anxiety and depression, was also investigated.
Methods
The study was cross-sectional. The sample consisted of 105 end-of-life cancer patients and 40 HCPs. Patients had a Karnofsky Performance Status of 50 or lower and a life expectancy of less than 4 months. For each patient, sociodemographic data were collected, and a set of rating scales assessing compassion, dignity as well as physical and psychological symptoms were administered.
Results
The results showed significant negative associations between patients’ perception of compassion and dignity-related distress as well as significant negative associations between patients’ perception of compassion and patients’ symptoms.
Significance of results
Compassion seems to be involved in diminishing dignity-related distress and alleviating physical and psychological symptoms. Other studies are needed to understand whether patients’ symptoms or whether specific HCPs’ conditions influence compassion. Exploring compassion and at the end-of-life could encourage a dignity-conserving care.
Amputation as a life-saving measure for earthquake-trapped patients is supported by WHO and INSARAG guidelines. However, implementing these guidelines in highly stressful contexts can complicate decision-making. This report presents a case of life-saving amputation during the 2023 Turkey earthquake, adhering to recommended guidelines. The 16-year-old patient was trapped for 55 hours in a narrow corridor. Extensive interdisciplinary discussions led to the decision for a field amputation after alternative rescue attempts failed. Consent was obtained from the family, given the patient’s delirium. Meticulous planning and anesthesia using midazolam and ketamine ensured successful amputation with minimal blood loss. Challenges encountered during the disaster response were discussed. Delays in administering antibiotics, a lack of cervical protection, ethical dilemmas, psychological concerns, and legal implications were highlighted. Continued improvement and addressing ethical, legal, and psychological aspects are essential for optimal disaster response outcomes.
To capture the distortion of exploratory activity typical of patients with spatial neglect, traditional diagnostic methods and new virtual reality applications use confined workspaces that limit patients’ exploration behavior to a predefined area. Our aim was to overcome these limitations and enable the recording of patients’ biased activity in real, unconfined space.
Methods:
We developed the Free Exploration Test (FET) based on augmented reality technology. Using a live stream via the back camera on a tablet, patients search for a (non-existent) virtual target in their environment, while their exploration movements are recorded for 30 s. We tested 20 neglect patients and 20 healthy participants and compared the performance of the FET with traditional neglect tests.
Results:
In contrast to controls, neglect patients exhibited a significant rightward bias in exploratory movements. The FET had a high discriminative power (area under the curve = 0.89) and correlated positively with traditional tests of spatial neglect (Letter Cancellation, Bells Test, Copying Task, Line Bisection). An optimal cut-off point of the averaged bias of exploratory activity was at 9.0° on the right; it distinguished neglect patients from controls with 85% sensitivity.
Discussion:
FET offers time-efficient (execution time: ∼3 min), easy-to-apply, and gamified assessment of free exploratory activity. It supplements traditional neglect tests, providing unrestricted recording of exploration in the real, unconfined space surrounding the patient.
Digital platforms and social media have expanded the ways in which individuals can exercise their right to freedom of expression and obtain and diffuse information. At the same time, they have become a principal means for haters to express and spread their hate in ways that would have been unthinkable some years ago. Responsive to the challenge, the EU has progressively developed a broad range of instruments and tools to counter online hate speech. This chapter discusses the key characteristics of the EU arrangements made to fight digital hate speech, shedding light on what is a multi-faceted and daunting regulatory task.
Rapid technological development means that the ground on which recent academic studies and public debates about the future of work organisation are based is shifting too rapidly for predictions to be credible. Organisational studies scholars have provided a counterpoint to this futuristic, speculative debate about the world of tomorrow with studies that contextualise seemingly new trends within a longer history of industrial capitalism. In this article, using Moritz Altenried's The Digital Factory (2022) as a starting point, I further explore the historical contextualisation of two aspects of platform capitalism: its de-spatialisation and its use of “autonomy”.
More than two-thirds of women during childbearing years (20–39 years old) are overweight or obese in the United States, with protein intake among 20–49-year-old women being 1.6 times higher than recommended (75.4 g/day versus 46 g/day) that can be considered as a relatively high-protein diet (HPD). Both gestational obesity and HPDs during gestation adversely affect offspring health. This study investigates the impact of HPDs fed during gestation and lactation on obese mothers and their offspring in Wistar rats. Dams randomized to either a normal-protein diet (NPD) or HPD (n = 12/group). Pups from each maternal group were weaned to either NPD or HPD for 17 weeks (n = 12/group). No effect of maternal or weaning diet on food intake, body weight, or body fat/weight ratio was observed. However, NPD dams exhibited higher glucose area under the curve compared with HPD dams (p < 0.03). At weaning, offspring born to NPD dams showed higher fasting plasma glucose (P < 0.03) and insulin/glucose ratio (P = 0.05) than those born to HPD dams. The Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) index was higher in offspring born to NPD dams (P < 0.04) and weaned to NPD (P < 0.05) at week 17. These findings underscore the role of high-protein maternal and weaning diets in pregnancy outcomes for obese mothers, particularly in glucose homeostasis, although gestational obesity may overshadow other parameters. Further research is needed to fully understand the impact on both maternal and offspring health and their underlying mechanisms in this context.
Generalized Poisson (GP) distribution was introduced in Consul & Jain ((1973). Technometrics, 15(4), 791–799.). Since then it has found various applications in actuarial science and other areas. In this paper, we focus on the distributional properties of GP and its related distributions. In particular, we study the distributional properties of distributions in the $\mathcal{H}$ family, which includes GP and generalized negative binomial distributions as special cases. We demonstrate that the moment and size-biased transformations of distributions within the $\mathcal{H}$ family remain in the same family, which significantly extends the results presented in Ambagaspitiya & Balakrishnan ((1994). ASTINBulletin: the Journal of the IAA, 24(2), 255–263.) and Ambagaspitiya ((1995). Insurance Mathematics and Economics, 2(16), 107–127.). Such findings enable us to provide recursive formulas for evaluating risk measures, such as Value-at-Risk and conditional tail expectation of the compound GP distributions. In addition, we show that the risk measures can be calculated by making use of transform methods, such as fast Fourier transform. In fact, the transformation method showed a remarkable time advantage over the recursive method. We numerically compare the risk measures of the compound sums when the primary distributions are Poisson and GP. The results illustrate the model risk for the loss frequency distribution.
Identify which NIH Toolbox Cognition Battery (NIHTB-CB) subtest(s) best differentiate healthy controls (HC) from those with amnestic mild cognitive impairment (aMCI) and compare the discriminant accuracy between a model using a priori “Norm Adjusted” scores versus “Unadjusted” standard scores with age, sex, race/ethnicity, and education controlled for within the model. Racial differences were also examined.
Methods:
Participants were Black/African American (B/AA) and White consensus-confirmed (HC = 96; aMCI = 62) adults 60–85 years old that completed the NIHTB-CB for tablet. Discriminant function analysis (DFA) was used in the Total Sample and separately for B/AA (n = 80) and White participants (n = 78).
Results:
Picture Sequence Memory (an episodic memory task) was the highest loading coefficient across all DFA models. When stratified by race, differences were noted in the pattern of the highest loading coefficients within the DFAs. However, the overall discriminant accuracy of the DFA models in identifying HCs and those with aMCI did not differ significantly by race (B/AA, White) or model/score type (Norm Adjusted versus Unadjusted).
Conclusions:
Racial differences were noted despite the use of normalized scores or demographic covariates—highlighting the importance of including underrepresented groups in research. While the models were fairly accurate at identifying consensus-confirmed HCs, the models proved less accurate at identifying White participants with an aMCI diagnosis. In clinical settings, further work is needed to optimize computerized batteries and the use of NIHTB-CB norm adjusted scores is recommended. In research settings, demographically corrected scores or within model correction is suggested.
Coronavirus disease 2019 can be indistinguishable from lower respiratory tract infections (LRTIs) caused by other viral and bacterial agents. This likely contributed to antimicrobial use (AU) and antimicrobial resistance (AMR) during the pandemic. Our antimicrobial stewardship program targeted the selection and duration of therapy for LRTIs and led to a reduction in AU and AMR.
