Limiting Freedom of Religion in a Pandemic: The Constitutionality of Restrictions on Religious Gatherings in a Response to COVID-19
Authors: Boutilier Misha
Published: April 2024

Restrictions on religious gathering as a response to the COVID-19 pandemic are a contentious issue. This article surveys the measures restricting religious gatherings and the legal challenges to those measures. There are three principal arguments that restrictions on religious gatherings are unconstitutional: (1) they lack instrumental rationality; (2) they are discriminatory; and (3) their deleterious effects outweigh their salutary effects. While the restriction measures likely limit section 2(a) and potentially section 15(1) rights under the Charter, these limits are justified because less restrictive alternatives to the measures are not equally effective, the measures are non-discriminatory, and their contribution to protecting Canadians from illness and death outweigh their deleterious effects. The article concludes with recommendations for future government measures directed at religious gatherings.
Gamete Donor Anonymity: What's Privacy Got to Do with It?
Authors: Procenko Natasha
Published: April 2024

In Canada, gamete donor anonymity is tacitly protected in the absence of laws or regulations that explicitly address the topic. This article explores and characterizes the historical and contemporary role of privacy, as a publicly protected legal interest, in the context of gamete donation. Ultimately, this article argues that anonymous gamete donation is not supported by the principle of privacy in Canadian law. The argument proceeds by identifying and exploring three candidate rationales for gamete donors’ interests in privacy as referenced in past and current government reports, legislation, and case law, but ultimately reveals them as wanting and unfounded from a legal standpoint. The implication of this is that the protection of donor anonymity cannot find support in appeals to donors’ privacy interests, and that the legal defensibility of the practice — if it can be defended at all — must be found elsewhere.
Legal Ethics for Government Lawyers: Confronting Doctrinal Gaps
Authors: Martin Andrew Flavelle
Published: April 2024

Despite the recent growth in the Canadian literature on legal ethics for government lawyers, the leading conceptual models have yet to be applied to resolve many of the most important legal questions facing government lawyers. In this article, I identify four key situations where the obligations of government lawyers as lawyers appear to clash with their obligations as public servants. I provide both a doctrinal analysis of how the current law applies in those situations and proposals for how the law can be clarified and improved. This analysis both provides much needed guidance to government lawyers and promotes a greater understanding by law societies as regulators, as well as other key stakeholders, of the unique challenges facing government lawyers and the need for legislative and regulatory reform.
Expert Evidence Admissibility: From Rocky Highlands to Swampy Lowlands, via the Medical Standard of Care
Authors: Garon-Sayegh Patrick
Published: April 2024

This article proposes an alternative research program for expert evidence law scholarship. The program takes a path that diverges from the majority of writing in this field, in two main ways. First, it eschews the field’s predominant epistemological stance. This stance — termed “epistemological rectitude” — primarily emphasizes fact-finding accuracy and rigorous admissibility or “gatekeeping” standards. Second, the proposed program adopts a narrower focus of inquiry than that usually taken: instead of experts in general, the program examines specific types of experts employed in specific types of cases to prove specific elements in dispute. Part I begins by presenting the current state of expert evidence law and highlighting the epistemological rectitude animating both case law and commentary. It then explains how epistemological rectitude elides the degree to which expert evidence law is highly pragmatic and contextual in its practical operation, and the problem that this entails for legal knowledge. To respond to this problem, the proposed program employs a context-driven method, presented at the end of Part II. Part III unpacks and defends this method by adopting a narrow focus: expert evidence on the medical standard of care in malpractice cases. This narrow focus is adopted to show: the limitations inherent to studying experts in general; the extent to which contextual differences matter to the law’s operation; and the knowledge to be gained by narrowing inquiries in this manner. The conclusion outlines in broad terms how the proposed program can be developed.
Alberta's Renewable Energy Market: Developing Contract Issues
Authors: Jeffers Scott , Clarke Ian , Eeles David , Mitchell Lincoln , Acworth Robin , Havart-Crans Kyle
Published: April 2024

Governments and corporations around the world have increasingly demonstrated leadership in tackling climate change, resulting in new decarbonization policies and initiatives and new corporate environmental, social, and governance mandates. At the same time, wind and solar capital costs have decreased and new technologies, such as battery storage, are becoming more prevalent, thereby increasing the flexibility and utility of renewable energy generation. Developers and investors have already expended significant capital to further the development of renewable generation with, according to the International Energy Agency, renewable energy investment reaching its highest level ever in 2021 — $367 billion internationally. This trend is only expected to increase if the global decarbonization goals are to be realized.
Within Canada, Alberta is at the forefront of renewable energy development due in part to its unique power industry structure — a deregulated, competitive, wholesale power market with non-discriminatory system access — which has attracted corporate off-takers and buoyed investment in renewable energy projects in the province, supported by corporate power purchase agreements. The pace of development is striking, and Alberta has rapidly become a preferred destination for renewable energy investment. The Alberta Electric System Operator says that 22 percent of the energy generated in Alberta in 2021 came from renewable energy sources. This is predictedto rise sharply — for instance, there are 61 solar projects currently under development in Alberta that could be completed by the middle of the decade.
This article examines several emerging contracting and development challenges currently facing renewable energy projects in Alberta, and aims to provide concrete, practical advice on several discrete contractual issues. Topics covered include, among others: (1) force majeure issues faced by project developers; (2) diverse carbon offset/renewable attributes programs and implications for power purchase arrangements; (3) developments pertaining to ethical procurement, including forced labour and the use of tracing protocols; and (4) the need for increased flexibility in contractual arrangements to accommodate the pairing of wind and solar with storage resources. Although this article is based primarily on experiences gained while developing renewable energy projects in Alberta, the analyses and solutions presented can be applied in many jurisdictions.
Richard Riegert Memorial Lecture: Ownership Issues in the Production of Geothermal Energy
Authors: Percy David
Published: April 2024

Alberta passed the Geothermal Resources Development Act (GRDA) to encourage the growth of a nascent geothermal industry. However, the GRDA fails to determine the respective rights of mineral owners and surface owners to exploit geothermal resources. It adds significant transaction costs to projects, as it forces proponents to obtain the consent of surface owners and potentially multiple owners of minerals on each affected parcel of land. The author concludes that the GRDA stands on an unreliable foundation and discourages the development of geothermal resources. A declaration of Crown ownership of the geothermal resources or retroactive legislation that precisely defined the parties who own the rights to geothermal resources would be more conducive to developing an industry that can produce energy without significant greenhouse gas emissions.

Federalism and the Arbitration of Consumer and Employment Disputes in the United States and Canada: The Road Not Taken?
Authors: Alcolea Lucas Clover
Published: April 2024

In many respects, the tale of the arbitration of consumer and employment disputes in the United States and Canada is a similar one. Both jurisdictions were traditionally hostile to arbitration, both jurisdictions had a complete change of heart in recent years, and in both jurisdictions, arbitration is widely used in the consumer and employment sphere. Moreover, in both jurisdictions questions have been asked regarding the fairness of arbitration agreements in consumer and employment contracts due to the inherent power imbalance between consumers or employees on the one hand and businesses or employers on the other. Despite these similarities, the consumer and employment arbitration landscape in each is radically different, whereas consumer and employment arbitration in the US is almost impossible for consumers and employees to avoid; in Canada, the opposite is true. This radical difference results from key differences in each jurisdiction’s understanding of federalism so that whilst Canadian provinces and courts have been able to protect consumers and employees, US states and courts have found themselves hamstrung by the Supreme Court’s interpretation of the Federal Arbitration Act and the dominance of federal law over state law. This has led to US courts pushing the envelope of the doctrine of unconscionability whilst Canadian courts have found this unnecessary due to provincial regulation. This article analyzes the different paths taken by federalism in each jurisdiction and how that in turn led to almost opposite outcomes for arbitration law north and south of the world’s longest border. Ultimately, the article concludes that in both federalism and arbitration law, Canada and the US each represent the road not taken by the other.
Twenty Years After Krieger v Law Society of Alberta: Law Society Discipline of Crown Prosecutors and Government Lawyers
Authors: Flavelle Martin Andrew
Published: April 2024

Krieger v. Law Society of Alberta held that provincial and territorial law societies have disciplinary jurisdiction over Crown prosecutors for conduct outside of prosecutorial discretion. The reasoning in Krieger would also apply to government lawyers. The apparent consensus is that law societies rarely exercise that jurisdiction. But in those rare instances, what conduct do Canadian law societies discipline Crown prosecutors and government lawyers for? In this article, I canvass reported disciplinary decisions to demonstrate that, while law societies sometimes discipline Crown prosecutors for violations unique to those lawyers, they often do so for violations applicable to all lawyers — particularly extraprofessional misconduct. Further research remains necessary on the patterns and incentives underlying law society discipline of Crown prosecutors and government lawyers. Nonetheless, the relative rarity of disciplinary proceedings involving Crown prosecutors and government lawyers does not necessarily mean that law societies are neglecting their statutory mandate as it applies to those lawyers. At the same time, law societies may indeed be overly reliant not only on internal discipline of these lawyers by governments as their employers, but also on criminal proceedings as prompts for investigation and discipline.

The Invention of Advantage: Annapolis Group v. Halifax Regional Municipality and Canadian De Facto Expropriation Law
Authors: Phillips Jim
Published: April 2024

This essay, through exploring the evolution of de facto expropriation in Canada, argues that the Supreme Court of Canada has recently “reformulated” the test for de facto expropriation by inaccurately representing what its own prior cases stated. The Supreme Court asserted that no more than an “advantage” has to be acquired by the state, not an interest in property. After analyzing the Supreme Court’s prior precedents, the article contrasts them with what the Supreme Court said they stood for in its most recent case, Annapolis Group v. Halifax Regional Municipality.

Effect of Gallic Acid on PTZ-induced Neurotoxıcıty, Oxidative Stress and Inflammation in SH-SY5Y Neuroblastoma Cells
Authors: Yazğan Yener
Published: April 2024

Aim: Human neuroblastoma cell lines are widely used to elucidate the cellular and molecular mechanisms of neurotoxicants and to facilitate the prioritization of in vivo testing. Pentylenetetrazole (PTZ) is a tetrazole derivative. Although PTZ is the most commonly used chemical to create an in vivo and in vitro epilepsy (EP) model, its mechanism of action in neuronal cells has not been fully elucidated. Gallic acid (GA) has broad biological properties such as antioxidant, anti-microbial, and anti-inflammatory activities. This study aimed to investigate the effect of GA on PTZ-induced neurotoxicity in neuroblastoma cells.

Methods: For the study, four groups were formed from SH-SY5Y neuroblastoma cells as control (C), GA (100 μM), PTZ (30 μM), and PTZ+GA. In the study, total antioxidant and oxidant status (TAS and TOS), inflammatory cytokines (TNF α, IL 1β, and IL 6), lipid peroxidation levels as malondialdehyde (MDA), glutathione peroxidase (GSHPx), and glutathione (GSH) levels in the SH-SY5Y neuroblastoma cells were determined.

Results: The results showed that PTZ treatment caused neurotoxicity in the neuroblastoma cell line and increased TOS, TNF α, IL 1β, IL 6, and MDA levels while decreasing TAS, GSH, and GSHPx levels. This situation improved with GA treatment.

Conclusion: As a result, it was determined that GA treatment showed a protective effect in the PTZ-induced neural toxicity model in SH-SY5Y human neuroblastoma cell lines.

Published: April 2024

Aim: Frozen shoulder, characterized by synovial inflammation and joint capsule fibrosis, impacts shoulder mobility and comfort. With the rise of online health information seekers, assessing the credibility of YouTube videos on frozen shoulder is crucial. This study aims to explore potential differences between physician and non-physician contributors by assessing the quality of Youtube videos using the DISCERN and JAMA scoring systems.

Methods: The first 50 YouTube videos found by searching with the word "Frozen shoulder" were examined; Short, repetitive titles and non-English content were not included in the study. Videos were categorized by content type, uploader, and key metrics of the videos were recorded. Two observers independently scored the videos using DISCERN and JAMA systems.Statistical analysis was performed, including Mann-Whitney tests and Spearman correlation..

Results: While 45 of the 50 videos contained real images, 5 were animations. Physiotherapists were the most contributing group (40%), and 60% of the videos contained general information about frozen shoulder. Considering the average DISCERN and JAMA scores, videos were mostly rated poor in quality. No statistically significant differences were found between the videos uploaded by physicians and non-physicians. Observer agreement was excellent.

Conclusion:Internet users searching for information about frozen shoulder face difficulties in distinguishing reliable content. Healthcare professionals should share videos with accurate information and direct patients to reliable online resources..

Authors: Ahlatcı Adem , Yıldızhan Kenan , Taşkıran Ahmet Şevki
Published: April 2024

Aim: Neurodegeneration is the progressive loss and structural deterioration of neuronal cells. Hydrogen peroxide (H2O2) is formed by dismutation and causes oxidative stress in neuronal cells. Venlafaxine is a drug that increases both serotonin and noradrenaline in the synaptic gap.In this study, the effect of venlafaxine on H2O2-induced cytotoxicity in C6 cells was investigated.

Methods: First of all, different doses of venlafaxine (25, 50, and 100 µM) were tried to find the appropriate dose in C6 glioma cells. Then, the effect of venlafaxine on H2O2-induced cytotoxicity in the cells was investigated. For this purpose, cell viability rate, proinflammatory markers IL-1β and TNF-α, and NO and iNOS levels were examined by ELISA kits.

Results: H2O2-treated caused cytotoxicity in the C6 glioma cells; when venlafaxine 25, 50, and 100 μM doses were evaluated in terms of cell viability, it was observed that the 100 μM venlafaxine applied group significantly increased cell viability compared to the other groups. When we look at the levels of IL-1β and TNF-α, it is observed that there is an increase in the H2O2 applied group and a significant decrease in the venlafaxine (100 μM) applied group. It was observed that NO and iNOS levels increased in the H2O2 applied group compared to the other groups. It was observed that Venlafaxine treatment reduced the increased NO and iNOS levels caused by H2O2.

Conclusion: The study results showed that venlafaxine may have a protective effect on H2O2-induced cytotoxicity in C6 glioma cells.
Международный опыт стимулирования роботизации: особенности и факторы эффективности

В статье рассмотрены политика России и ряда индустриально развитых стран в области роботизации на горизонте 2015–2020 гг., оценивается эффективность их ключевых направлений. Отмечены существенные различия в подходах к государственному стимулированию роботизации: лишь в некоторых странах имеется соответствующая стратегия, разная роль отводится взаимодействию с бизнесом, довольно редко встречается поддержка образовательных проектов. И если государственное финансирование НИОКР практикуется повсеместно, то поддержка внедрения их результатов характерна лишь для части стран. Результаты проведенного анализа свидетельствуют о значительном положительном влиянии на роботизацию государственной стратегии и поддержки НИОКР. При этом не удалось выявить влияния государственных инициатив по подготовке кадров, что, однако, может быть обусловлено существенными лагами наступления заметного в масштабах национальной экономики эффекта от подобных мер.
Нехватка работников в сельском хозяйстве России: есть ли потенциал для восполнения?
Authors: Потапова А.А.
Published: April 2024

Автор анализирует потенциал российского рынка труда для восполнения дефицита кадров в сельском хозяйстве, который в 2023 г. Минсельхозом РФ был оценен в 200 тыс. чел. Ключевой вывод – при сложившемся размещении производительных сил в сельском хозяйстве России внутренний потенциал для обеспечения дефицита кадров ограничен. Наблюдается несоответствие вакансий и соискателей по образованию и квалификации, несовпадение трудоизбыточных и трудодефицитных регионов. В отдельных из них уровень оплаты в сельском хозяйстве выше, чем по региональной экономике, но ниже, чем в целом по экономике России. Низкий уровень оплаты труда не дает стимулов для внутренней миграции работников. Улучшение условий проживания на сельских территориях не может в полной мере решить проблему нехватки кадров в сельском хозяйстве.

Published: April 2024

Infrastructure growth requires large quantities of concrete, a problem of concern distance between the batching plant and location of different casting locations, the process mixing and transporting to casting location requires time that can exceed the cement setting time. Plastiment helps improve the strength, durability and general quality of concrete. This research aims to determine the compressive strength of concrete at setting times of 60, 90 and 120 minutes using 150 mm x 300 mm specimens with variations in addition of plastiment of 0.20% and 0.40% of the cement weight. Primary data the form of material testing data and concrete compressive strength for each variation and secondary data is in the form of additives and the properties of cement used. The test results show that the compressive strength of concrete at 60, 90 and 120 minutes by adding Plastiment® P-121R at a variation of 0.20% is 17.55, 18.12 and 18.85 MPa while giving a dose of 0.40% is 17 .27, 19.82 and 22.08 MPa. Addition of plaster can meet the slump value requirements at each time variation and in contrast to normal concrete the slump value is not met at each time variation with the concrete having dried during mixing.

Вызов постгуманизма и предельные основания бытия человека
Authors: Новопашин Сергей
Published: April 2024

Transhumanism and posthumanism of their potential hypothetical bearers (“transhumans”, “posthumans”), require philosophical reflection, since they concern the evolution of humans, his adaptation to the inherently inhuman digital technosphere, and as a result – not only the biological survival of the species Homo sapiens, which is only possible if there is a sense of existence (realized through spiritual evolution), but the preservation of the “human” in it, the preservation of its ontological foundations. The author believes that the main problem associated with the challenge of trans- and posthumanism is the need to comprehend the ultimate foundations of human existence. The object of the study is a person taken together in the ultimate foundations of his being, his development, in the ultimate dimension of his evolutionary development. The subject of the study is the ability of a person in his socio-cultural intentions to overcome or not to overcome the crisis; in the first case, the further development of a person follows, in the second – his development becomes post-human. The methodological basis of the study was the principles of historical, comparative and interdisciplinary approaches. The novelty of the findings lies in the ontological-theological interpretation of the supposed ontological status of a hypothetical post-human.

Authors: Trojan O.I. , MURAVSKA O.M.
Published: April 2024

Objective — to improve the results of treatment of patients with intramedullary ependymomas.
Materials and methods. The results of treatment of 29 patients (14 men and 15 women aged 18 to 64 years) with intramedullary ependymomas operated on at the Romodanov Institute of Neurosurgery of the National Academy of Medical Sciences of Ukraine were analysed. All patients who were scheduled for surgery underwent magnetic resonance imaging (MRI) with paramagnetic contrast agent. The preoperative and postoperative neurological status was assessed using the modified McCormick scale.
Results. Microsurgical technique for removal of spinal cord tumors was used in all 29 observations. According to the volume of tumor removal, operations with total (12 observations), subtotal (9 observations) and partial (8 observations) removal were distinguished. Removal of at least 95 % of the tumor volume, which was confirmed by visualization with a microscope during surgery and early postoperative MRI, was considered total. At the time of discharge from the hospital, in 11 patients (37.9 %) the neurological condition improved compared to the preoperative period, in 13 (44.8 %) it remained unchanged, and in 5 (17.2 %) there was an increase in neurological symptoms. 12 patients were examined 12—36 months after the operation. Improvement compared to the preoperative period was found in 10 patients, and no changes in 2. There were no cases of worsening of neurological symptoms during this period. MRI performed before discharge from the hospital showed almost normal spinal cord diameter in the area of surgical procedures, and MRI performed ≥ 3 months after total tumour removal showed atrophic changes in the spinal cord with ependymoma localisation at the thoracic level.
Conclusions. Intramedullary ependymomas can be totally removed, and surgical intervention must be carried out immediately after the diagnosis before the appearance of signs of increasing neurological deficit. Thanks to the use of microsurgical techniques and an intraoperative microscope, it is possible to achieve positive functional results during the total removal of intramedullary tumors.

The study focuses on stroke, the second leading cause of death worldwide. It specifically addresses the ischemic type of stroke, which constitutes the majority of cases globally and in Ukraine, driving the search for innovative and effective diagnostic and treatment strategies. Among these, reperfusion of brain tissue within the first hours of the disease can prevent irreversible brain damage or minimize its extent, thus reducing the degree of residual neurological deficit.
Objective — to compare the outcomes between standard therapy and thrombolytic therapy (TT) in treating ischemic stroke, evaluating the efficacy of TT within the standard therapeutic window to optimize patient care.
Materials and methods. The study was conducted in the Neurological Department No. 2 of Kyiv City Clinical Hospital No. 4 from July to December 2023. A total of 247 cases of ischemic type stroke were analyzed. 69 patients who were admitted within the standard therapeutic window were selected. They were divided into two groups. The experimental group included 42 patients aged between 42 and 89 years (average age — (71.0 ± 17.8) years) without contraindications, who agreed (themselves or through relative’s consent) to undergo TT. Alteplase was administered intravenously at a dose of 0.9 mg/kg body weight, 10 % of the dose as a bolus (over 1 minute), and 90 % within one hour. The control group consisted of 27 patients aged between 47 and 88 years (average age — (76.11 ± 8.9) years), who had contraindications for TT. They received standard therapy. Evaluations were conducted using the modified Rankin Scale, which allows for assessing the level of disability or dependence on external assistance in patients’ daily lives after a stroke.
Results. The study demonstrated that TLT significantly improves the functional status of patients compared to standard therapy, as evidenced by a decrease in the level of disability to 0—1 points on the modified Rankin Scale at discharge from the hospital: in the control group — in 3 (11.1 %) patients, in the experimental group — in 16 (35.7 %, p = 0.047), i. e. the use of TLT significantly improved the functional status of more patients. In the experimental group, 4 patients died (9.5 %), in the control group — 5 (18.5 %).
Conclusions. TLT effectively promotes the restoration of neurological functions and reduces the level of disability in patients with ischaemic cerebral stroke, which opens up prospects for further research. The results obtained indicate the need for wider use of TLT in clinical practice, taking into account individual patient risks and contraindications.
Effects of Birth Order on Human Sexuality: the Sex of Siblings Matters
Authors: Daňková Hana , Kuba Radim , Flegr Jaroslav
Published: April 2024

Birth order is known to influence various personality dimensions, from intelligence to personality traits; however, its relationship with human sexuality remains substantially underexplored. This study aimed to investigate the relationship between birth order and aspects of human sexuality, specifically: onset of sexual activity, sociosexual orientation, lifetime number of sexual partners, and sexual dominance. Data on birth order and sexuality were procured through a large-scale online questionnaire circulated among the Czech population, with the final analysis sample (N = 4,495) comprising respondents from two-child families. Significant differences were observed between firstborn and secondborn individuals. Notably, secondborns initiated their sexual activity earlier, while associations between birth order and number of sexual partners were contingent on the sex of the respondents and their siblings. No association between birth order and sociosexual score (measured with the SOI-R) was observed in women, and only a weak association was found in men. Both dominant and submissive sexual preferences correlated with higher birth order in both sexes. Our findings indicate that firstborn and secondborn individuals exhibit differences in sexual desires, behaviors, attitudes, and preferences. Future research exploring the relationship between birth order and sexual behavior/preferences should account for sibling sex as a pivotal factor.
Modeling the initial state of early phonetic learning in infants

Published: April 2024

What are the necessary conditions to acquire language? Do infants rely on simple statistical mechanisms, or do they come pre-wired with innate capabilities allowing them to learn their native language(s)? Previous modeling studies have shown that unsupervised learning algorithms could reproduce some aspects of infant phonetic learning. Despite these successes, algorithms still fail to reproduce the learning trajectories observed in infants. Here, we advocate that this failure is partly due to a wrong initial state. Contrary to infants, unsupervised learning algorithms start with little to no prior knowledge of speech sounds. In this work, we propose a modeling approach to investigate the relative contribution of innate factors and language experience in infant speech perception. Our approach allows us to investigate theories hypothesizing a more significant role of innate factors, offering new modeling opportunities for studying infant language acquisition.
Cognitive Bias and Mate Choice
Authors: Dawson Christopher
Published: April 2024

Sexual mates resemble each other on physical traits, personality factors and political opinion. We extend this line of research to one of the most prominent cognitive biases, unrealistic optimism—the tendency for individuals to overestimate the chance of favourable outcomes occurring and underestimate the chance of bad. Using data from a national representative sample of the English population over age 50, we find that there is a moderate alignment of mates on cognitive bias, similar in range to broad personality factors. Importantly, we also provide evidence that these similarities are driven by direct selection on bias rather than social homogamy, and initial mate choice rather than transmission mechanisms, such as persuasion and imitation. We discuss the implications of mate selection on cognitive bias in the context of household decision-making, income inequality and intergenerational transmission.
Attributing extreme weather to climate change: State Park employees as institutional actors

Published: April 2024

Researchers in environmental psychology celebrate the potential for state and national parks to inspire civic engagement in the issue of climate change. Yet, prevailing conceptions of nature may reflect ongoing colonial concerns, such that parks may represent a space to avoid thinking about—rather than reckon with—escalating ecological crises. In this paper, we approach the topic of climate change in state parks from a perspective informed by decolonial theory. In particular, we report a mixed-methods study with (N = 51) employees at parks in Kansas and throughout the United States regarding the extra-individual factors that impact their tendency to subjectively attribute extreme weather to climate change. Findings indicate that park employees were less likely to attribute extreme weather to climate change in parks with (1) less institutional support for climate change mitigation, and (2) increased presence of white conservatives. Responses to a question about the purpose of parks and open-ended reflections reveal that employees conceive of parks as a space for recreation wherein their primary role in relation to visitors is to supply “fun” and “natural” experiences for consumption. We reflect on conceptions of parks and nature and discuss a conception of parks better suited to confront the escalating ecological crisis.
