The impact of racism to the individual is arguably immeasurable; however, the impact on psychotherapists who themselves have personally had either one or multiple experiences of racism and work with clients in therapy who have also experienced racism is an area with very little research. Semi-structured interviews were conducted with black cognitive behavioural therapists who have personally experienced racism and have also worked with clients who have experienced racism; data were analysed using interpretive phenomenological analysis. As this was a pilot study, only two participants were recruited to the study. Superordinate and subordinate themes were identified from the data and explored. The study highlighted that the impact of racism, racist experiences and microaggressions can lead to mental health problems, and there is need for further support for therapists, especially within the contexts of clinical supervision and from their organisation leadership. In addition, the need for further research was also identified, as well as improved training in working with disclosures of racism, and racial trauma within a therapeutic context was considered as important to the therapists of this pilot study.

U.S. national policies toward Native Americans followed a zig-zag path of change from 1889 to 1970. How do we explain policymakers’ unsteady attraction to the rights of Native Nations? I argue that in precarious circumstances, Native Americans forged interest-based political coalitions with non-Native American western rural interests. At times, this cross-racial, interest-based coalition successfully challenged the power of non-Native American eastern ideologues. These findings advance our understanding of the interplay of race and federalism. Also, these findings illustrate the unique importance of Native Nations for American political development. This article presents quantitative and qualitative analyses of a new dataset on federal Indian policy. It also reviews existing historical scholarship.

With a focus on the risk contribution in a portofolio of dependent risks, Colini-Baldeschi et al. (2018) introduced Shapley values for variance and standard deviation games. In this note we extend their results, introducing tail variance as well as tail standard deviation games. We derive closed-form expressions for the Shapley values for the tail variance game and we analyze the vector majorization problem for the two games. In particular, we construct two examples showing that the risk contribution rankings for the two games may be inverted depending on the conditioning threshold and the tail fatness. Motivated by these examples, we formulate a conjecture for general portfolios. Lastly, we discuss risk management implications, including the characterization of tail covariance premiums and reinsurance pricing for peer-to-peer insurance policies.

The crystal structure of meglumine diatrizoate has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Meglumine diatrizoate crystallizes in space group P21 (#4) with a = 10.74697(4), b = 6.49364(2), c = 18.52774(7) Å, β = 90.2263(3), V = 1292.985(5) Å3, and Z = 2. Two different crystal structures, which yielded essentially identical refinement residuals and positions of the non-H atoms, were obtained. The differences were in the H atom positions and the hydrogen bonding. One structure was 123.0 kJ/mol/cell lower in energy than the other and was adopted for the final description. The crystal structure consists of alternating double layers of cations and anions along the c-axis. The hydrogen bonds link the cations and anions into a three-dimensional framework. Each of the hydrogen atoms on the ammonium nitrogen of the cation acts as a donor in a strong N–H⋯O hydrogen bond. One of these is to a hydroxyl group of another cation, and the other is to the carboxylate group of the anion. Each of the amide nitrogen atoms of the anion forms a strong N–H⋯O intermolecular hydrogen bond, one to a carbonyl and the other to a carboxylate group. The powder pattern has been submitted to ICDD for inclusion in the Powder Diffraction File™ (PDF®).

In the late twentieth century, the European Union (EU) emerged as a global leader in setting environmental protections, including vehicle emissions standards. But member state consensus around environmental rules did not come easily, and the regional norms eventually set by the EU and its predecessor, the European Economic Community, had complex origins. This article argues that common emissions standards were ultimately achieved through a public-private process during the program to create the Single European Market in the 1980s and 1990s. For regional policymakers, standards were key to achieving an internal car market and strengthening the auto industry's global competitiveness; for many European carmakers and their transnational business associations, common norms could facilitate economies of scale and level the playing field. The “liberal environmentalism” born out of this convergence of interests produced common standards that fell pragmatically between the greenest member states and those most invested in protecting their national champion firms.

Archaeologists should always have their say in the interpretation of the archaeological record. Moreover, they should not allow those interpretations to be misappropriated by others, whether politicians, journalists or specialists of other disciplines. By contending that borders are a timely topic for archaeological attention, Emily Hanscam and Brian Buchanan (2023) make a decisive epistemological step forward within the field, also opening up the potential of the discipline's specialised knowledge for wider dissemination and impact. They advance from a straightforward position: the argument that re-bordering in the contemporary world, notably through the increasing fencing of borders (Bissonnette & Vallet 2020), often originates in a normative and normalising discourse on the past. The best example, according to the authors, is Hadrian's Wall, which appears as a common justification for the building of contemporary walls on a growing number of international borders. Their text unfolds a comparison between the archaeological findings about that one short segment of the Roman limes in northern Britain and the supposed properties of the contemporary infrastructure on the US/Mexico border, which successive US presidents have sought to reinforce—chief among them Donald Trump.

The congruency effect—that is, faster and more accurate processing of congruent multiword units, has been demonstrated in multiple studies. It is still unclear, however, what its underlying mechanism is, and how congruency may interact with other factors. Using an acceptability judgement task, this study examined the congruency effect in immersive (Experiment 1) and nonimmersive (Experiment 2) L2 learners’ collocational processing while taking into account L2 collocation frequency, immersive learners’ L2 use, their length and starting age of immersion, nonimmersive learners’ length of instruction, and their L2 proficiency. The study also tested whether L1 counterparts of words in L2 collocations were activated. Nonmmersive learners showed a congruency effect in both processing speed and accuracy. In contrast, immersive learners were affected by congruency only in processing accuracy. Higher L2 collocation frequency, greater length of instruction, and higher L2 proficiency did not reduce the congruency effect, whereas longer duration of immersion improved the processing of incongruent items. An effect of L1 lexical frequency was found, an indication of L1 activation. Results were discussed in light of how L2 proficiency and experiences changed the amount of L1 influence in L2 collocational processing.

Cetaceans in the eastern South Atlantic Ocean are poorly studied. We present results from a 2 week ship-based survey from Cape Town to Vema Seamount (980 km to the west) during October–November 2019, including visual and towed-hydrophone observations from the vessel, and 10 days of acoustic monitoring on the seamount. Fifty-two hours of visual surveys resulted in 39 encounters of whale groups including seven of humpback, six of fin and one sei whale, as well as four unidentified baleen whales, 18 unidentified balaenopterid whales and four unidentified odontocetes. Two humpback whales at the seamount were engaged in possible feeding behaviour. A large aggregation of mostly fin whales was observed near the continental shelf edge (22 encounters over a 70 × 50 km2 area, six fin, one sei whale, 15 not confirmed to species), an historic whaling ground for both fin and sei whales. Towed-hydrophone data (78.7 h) detected five groups of sperm whales, 45 of delphinids, one beaked whale and no Kogiids. Acoustic data from the seamount detected calls from several baleen whale species including humpback whale non-song calls, Antarctic minke ‘bioduck’ calls, sei whale down-sweep calls and a likely Bryde's whale call. Two call types could not be assigned to species, including the most detected – a simple frequency-modulated call with peak power around 130 Hz. This study contributes to an improved understanding of cetacean occurrence in the eastern South Atlantic Ocean and highlights the need for more research to improve identification of cetacean vocalizations in the region.

Mealtimes in long-term care (LTC) can reinforce relationships between staff and residents through relationship-centred care (RCC) practices; however, meals are often task-focused (TF). This cross-sectional study explores multi-level contextual factors that contribute to RCC and TF mealtime practices. Secondary data from residents in 32 Canadian LTC homes were analyzed (n = 634; mean age 86.7 ± 7.8; 31.1% male). Data included resident health record review, standardized mealtime observation tools, and valid questionnaires. A higher average number of RCC (9.6 ± 1.4) than TF (5.6 ± 2.1) practices per meal were observed. Multi-level regression revealed that a significant proportion of variation in the RCC and TF scores was explained at the resident- (intraclass correlation coefficient [ICC]RCC = 0.736; ICCTF = 0.482), dining room- (ICCRCC = 0.210; ICCTF = 0.162), and home- (ICCRCC = 0.054; ICCTF = 0.356) levels. For-profit status and home size modified the associations between functional dependency and practices. Addressing multi-level factors can reinforce RCC practices and reduce TF practices.

In this erratum, we correct an erroneous result in [PV2] and prove that the affine algebraic hypersurfaces $xy^2=1$ and $z=xy^2$ are not interpolating with respect to the Gaussian weight.

Two wideband bandstop filters (BSFs) for single and dual-band are proposed and then extended to reflectionless BSFs based on the analysis from input impedance/admittance perspective. Also, topologies of higher-number-stopband input-reflectionless BSF are provided to broaden the design scope. Open/shorted coupled lines are adopted to obtain multi transmission zeros and desired stopband bandwidth by adjusting the even-/odd-mode impedance of coupled lines. Resistor-loaded coupled lines are connected with Port 1 to absorb unwanted signals and obtain input-reflectionless behavior. For validation of the proposed theory analysis, BSFs with corresponding absorptive prototypes are constructed and measured.

This article explores how relations of both domination and resistance have been involved in the constitution of international hierarchies. Focusing on events arising from the Persian government’s 1932 cancellation of the D’Arcy oil concession, it argues that while Western-dominated international hierarchies have proved resilient, some aspects of these hierarchical relationships have been altered by episodes of resistance such as the one under examination in this article. The case study has been chosen because of its ability to highlight the interwar years as an important period of transition to a new world order, as well as the significance of Persia as one of the few non-Western countries that remained uncolonised at that time. The article revisits detailed historical documents from the BP Archives and the National Archives to show how the events of the 1930s oil dispute contributed to the emergence of shifts in the material, legal, and social hierarchies of the interwar period, while nevertheless reinforcing the existence of hierarchies overall. It shows how multilateral diplomacy replaced overt military intimidation, the framework of international law broadened, and peripheral countries found strength in numbers. Finally, the article considers the longer-term resilience of the hierarchical international system.

Background: Women continue to represent a minority of the neurosurgery workforce in Canada. We herein aim to provide an update of the current Canadian landscape to gain a better understanding of the factors contributing to this disparity. Methods: Chain-referral sampling, interviews, personal communications, and online resources were used as data sources. Online survey results obtained from women attending neurosurgeons across Canada were also utilized. Quantitative analyses were performed, including summary and comparative statistics. Qualitative analyses of free-text responses were performed using axial and open coding. Results: We observe a positive trend in the incoming and graduating of female residents across the country, although this trend is lagging compared to other surgical specialties. The proportion of women in active practice remains low. Positive enabling factors for success include supportive colleagues and work environment (52.6%), academic accomplishments (36.8%), and advanced fellowship training (47.4%). Perceived barriers reported included inequalities regarding career advancement opportunities (57.8%), conflicting professional and personal interests (57.8%), and lack of mentorship (36.8%). Conclusions: Women continue to represent a small proportion of practicing neurosurgeons across Canada. Our work highlights several key factors contributing to the low representation of women in neurosurgery and identifies actionable items that can be addressed by training programs and institutions.

Background: ALS is a progressive neurodegenerative disease without a cure and limited treatment options. Edaravone, a free radical scavenger, was shown to slow disease progression in a select group of patients with ALS over 6 months; however, the effect on survival was not investigated in randomized trials. The objective of this study is to describe real-world survival effectiveness over a longer timeframe. Methods: This retrospective cohort study included patients with ALS across Canada with symptom onset up to three years. Those with a minimum 6-month edaravone exposure between 2017 and 2022 were enrolled in the interventional arm, and those without formed the control arm. The primary outcome of tracheostomy-free survival was compared between the two groups, accounting for age, sex, ALS-disease progression rate, disease duration, pulmonary vital capacity, bulbar ALS-onset, and presence of frontotemporal dementia or C9ORF72 mutation using inverse propensity treatment weights. Results: 182 patients with mean ± SD age 60±11 years were enrolled in the edaravone arm and 860 in the control arm (mean ± SD age 63±12 years). Mean ± SD time from onset to edaravone initiation was 18±10 months. Tracheostomy-free survival will be calculated. Conclusions: This study will provide evidence for edaravone effectiveness on tracheostomy-free survival in patients with ALS.

Background: The Canadian Guideline for Parkinson Disease (PD) indicates clozapine and quetiapine are considered the only safe antipsychotics for people with PD, to avoid potentially exacerbating motor symptoms. In response to safety events in our centre, we explore contraindicated antipsychotic prescriptions being administered to hospital inpatients with PD to determine common factors and develop approaches to prevent future occurrences. Methods: Following a privacy impact analysis, the Interior Health Quality Improvement & Patient Safety Office identified inpatients at Kelowna General Hospital, between December 2018 and June 2021, with a coded diagnosis of PD. Pharmacy medication order and dispensing data were cross-referenced to determine patients exposed to a contraindicated antipsychotic for further chart analysis. Results: Of the 140 admissions with a PD diagnosis, 17 had at least one contraindicated antipsychotic prescribed or dispensed (12.1%). Loxapine (7) and haloperidol (6) were the most frequently prescribed. This occurred despite a diagnosis of PD being noted on admission in 14 cases, and 13 cases were known to be taking levodopa. Conclusions: These results demonstrate additional safety measures are needed to reduce the frequency of contraindicated antipsychotic prescriptions in this population. We propose developing a stepwise plan for behaviour de-escalation and pharmacological management.
