Critical Moment Research Articles

Recall as a Window into Hippocampally Defined Events.

We experience the present as a continuous stream of information, but often experience the past in parcels of unique events or episodes. Decades of research have helped to articulate how we perform this event segmentation in the moment, as well as how events and their boundaries influence what we later remember. More recently, neuroscientific research has suggested that the hippocampus plays a role at critical moments during event formation alongside its established role in enabling subsequent recall. Here, we review and explore the relationship between event processing and recall with the perspective that it can be uniquely characterized by the contributions of the hippocampus and its interactions with the rest of the brain. Specifically, we highlight a growing number of empirical studies suggesting that the hippocampus is important for processing events that have just ended, bridging the gap between the prior and current event, and influencing the contents and trajectories of recalled information. We also catalogue and summarize the multifaceted sets of findings concerning how recall is influenced by event structure. Lastly, we discuss several exciting directions for future research and how our understanding of events might be enriched by characterizing them in terms of the operations of different regions of the brain.

Rent controls in comparative perspective: Reflections on an international symposium

In Scotland, the policy landscape around rent controls is rapidly evolving and full of uncertainty. At this critical moment, an international symposium in Edinburgh brought together activists and academics in similar contexts living with or fighting for rent controls from across Europe and North America. This contribution is organised around reflections from the participants on (1) the history of rent controls in their area; (2) the current rent regulations in operation and their effectiveness; (3) the role of tenants’ organisations and (4) landlord and other pro-real estate lobbies in shaping the discourse around rent controls; and (5) reflections on what a satisfactory resolution on the rent control issue might look like and how it relates to other dimensions of the housing system. Our collective hope is that these reflections contribute to sharpening and clarifying the re-emergence of demands for rent control in Europe and North America as a powerful tool––if insufficient by itself––for shaping a decommodified housing system.

Media politics in Japan: News journalism between interdependence, integrity, and influence

AbstractAlthough Japan is generally considered a liberal democracy with a free press, concerns about media independence have repeatedly been raised. The World Press Freedom Index ranks Japan last among G7 nations. One of the major reasons for its performance lies in a deep-rooted entanglement of the mainstream media with the political establishment, which is said to promote a climate of self-censorship and impede courageous, critical journalism. While the government-approved reporters’ clubs (“kisha clubs”) are often cited as lying at the heart of the problem, there are other relevant structural and historically grown factors hindering the improvement of press freedom: Despite theoretical constitutional protection, media governance in Japan does not provide an adequate framework for journalistic independence; furthermore, revolving door politics, editorial interventions and informal arrangements are well-established practices inside the sphere of media and politics. Nevertheless, there have been those critical moments when the mainstream media, in fact, influenced the course of politics. Setting out from the present condition of media democracy in Japan, this article traces back the historical roots of the seemingly firmly ingrained relationship between journalism and the state. Thereby, it portrays the ambivalent interdependence between the media and politics, and the dilemmatic tension between journalistic integrity, economic interests, and political influence. Finally, it explains why the current hegemony of the legacy media in the public sphere may eventually face a silent, but profound transformation in light of digitization and advancements in artificial intelligence.

Scientific-technological progress in the face of ethics

Various symptoms and facts lead one to think that the utopia of scientific and technological progress, conceived in a linear, autonomous and unhindered manner - scientific and technological progressivism - is going through its first critical moment, of revision, and the time has come for a confrontation, ‘the realm of facts’ with the ‘realm of values’, between the scientific organisation of means with the meaning and direction of ends.

Stochastic modelling of uncertainty in Chilean radiata pine wood beams subject to lateral torsional buckling

ABSTRACT This paper aims to investigate the effect of the variability in the mechanical and cross-section properties of Chilean radiata pine on the lateral buckling strength of slender wooden beams. The study is conducted numerically through finite element modeling and using linear eigenvalue analysis. The numerical model is validated using experimental results available in the literature. Two approaches are employed in the analysis, firstly a deterministic approach using design of experiments (DOE) techniques to establish the relevance of the parameters, and secondly a stochastic one, through Monte-Carlo simulation to investigate the impact of each parameter on the lateral buckling resistance. Various distribution functions are considered to investigate the effect of uncertainties in the material parameters and their impact on the critical buckling moments. Moreover, Sobol indices indicated that from the total variability of the distribution of the critical moment, an average of 50% of the variability is attributed to the shear modulus G LR , 37% to the longitudinal elastic modulus E L , and a negligible percentage of the grain angle F .

Intersecting liminalities and transition rites: non-disclosure agreements and misconduct in organizations

ABSTRACT For what reasons may NDAs continue to be an attractive measure to conceal severe misconduct in organizations, despite high-profile criticism? I theorize severe misconduct as a critical moment of separation of victim-survivor, perpetrator, and the social order of the organization. This provokes liminalities and I read Giesen's four liminal phenomena (victims, monsters, garbage, and seduction) as imagination devices in the analysis of the accounts of those who have experienced severe misconduct. In doing so, I show that the multiplicative effects of these liminal phenomena intersect in such a disruptive manner that NDAs offer an attractive ceremony towards transition; a seductive way for organizational actors to transform/adjust the presence of victims and monsters, hiding and/or recycling their garbage. I contribute by theorizing meta-liminality and intersecting liminal phenomena emerging from severe misconduct in organizations, showing empirically examples of why NDAs may be used to ceremonially manage the transition in these cases.

Taking Liberty with Imagination and Gender in Northanger Abbey

In Northanger Abbey Austen presents the evolution and devolution of a romantic relationship that reveals what is lost when shame brings two non-heteronormative partners into a conventional social contract: the witty conversations and imaginative flights of fancy that Catherine Morland and Henry Tilney sustain in their courtship fade and finally disappear as they take their places in the symbolic order. Both experience a turning point in their development when Henry realizes and seemingly rebukes Catherine for suspecting that his father was responsible for his mother’s death. That critical moment changes everything for them, as they surrender their fluidity and pursue a more generic path to marriage that Austen’s metaleptic narrator cagily challenges as the novel concludes.

Edy App: Earthquake Mitigation Innovation Using GIS for Disaster Response in Pariaman, Indonesia

Pariaman City, located along the Semangko fault line and the subduction zone of the Indo-Australian and Eurasian plates, is highly vulnerable to earthquakes and tsunamis. The region's susceptibility to large earthquakes, followed by vertical deformations, highlights the need for effective disaster mitigation. In response, this study proposes the development of the Earthquake Buddy Application (EDY App), designed to assist with earthquake mitigation efforts. The EDY App leverages Geographic Information System (GIS) technology to map earthquake-prone areas, provide early warnings, suggest evacuation routes and Temporary Evacuation Sites (TES), and facilitate aid distribution. This Android-based mobile application focuses on four key aspects: education, mitigation, evacuation, and donation. Key features include an Earthquake Vulnerability Map, real-time early warnings, mitigation instructions, TES recommendations with distance and time estimations, emergency contact options, and donation channels. Built with React Native, PHP, and MySQL, and integrated with Google Maps API, the app is designed to be user-friendly and accessible to the public. The EDY App’s contribution to earthquake mitigation lies in its ability to create a disaster-aware community. By offering comprehensive information and support during critical moments, the app can potentially reduce casualties and enhance community preparedness in earthquake-prone regions like Pariaman. Through this innovation, it is expected that residents will be better equipped to respond to natural disasters, promoting a culture of safety and resilience.

Understanding the involvement/exclusion paradox in disaster volunteering from a field-theoretical perspective

In disasters, volunteers who have not been affiliated to official disaster response organisations are likely to enter the scene. Although such unofficial responders (UR) are increasingly recognised as a valuable resource in both research and practice, their full utilisation, integration, and cooperation with the official response (OR) is rare. Although researchers have increasingly examined the barriers and drivers of UR involvement, this “involvement/exclusion paradox”, coined by Harris et al. (2017), remains puzzling. Applying a field-theoretical perspective, this paper argues that disasters are critical moments in which the field itself is put under pressure at multiple focal points. For instance, UR who enter the scene and try to become involved jeopardize the field: they increase the number of involved agents, increase the competition over symbolic profit, and question the definition of proper disaster response. Taking a case-study of a mudslide disaster in the Austrian Alps, this paper examines the strategies by which OR tame pressure associated with UR. Three strategies were revealed: boundary definition, boundary defence, and boundary opening, which aim at establishing and upholding boundaries by increasing both their robustness and elasticity. The findings contribute to a theoretically underpinned understanding of UR involvement and encourage critical reflection on the relations between UR and OR by revealing tensions and latent conflicts.

Improving Advanced Care Planning: Documentation of DNA CPR Orders and TEPs in Residential Care Admissions

Abstract Background Do Not Attempt Cardiopulmonary Resuscitation (DNA CPR) orders and Treatment Escalation Plans (TEPs) are key components of advanced care planning for managing patients with progressive life-limiting illnesses and significant frailty. Our study aimed to determine the proportion of such patients being transferred from residential care facilities with documented TEPs upon medical admission, examine whether these TEPs were revised during the hospital stay, and assess patient outcomes at 14 days post-presentation. Methods We reviewed the lists of patients who had been referred for medical admission via the emergency department over a one-month period and identified those presenting from residential care facilities. We excluded those under the age of 65. We reviewed relevant medical notes and collected anonymised data into an Excel spreadsheet on a password protected computer. Results We identified 34 patient’s relevant patients. Notes were available for review in 31 cases (17 male; age range 66 to 96 years old, mean age 82.3). Of the 31 cases reviewed, the mean Clinical Frailty Score was 7.4. Residential care facilities sent documentation outlining TEPs in 19/31 cases. In those cases, 4/19 specified full resuscitation. In 3/4 of these cases, the TEP was revised during their admission. In one case, documentation specified that the patient did not want to be transferred to hospital under any circumstances. A total of 14 patients had no documentation regarding TEP. Of those, 7/14 went on to have DNA CPR orders filled out during their admission. At 14 days post presentation, 7 had died in hospital, 16 were discharged back to their residential care facility, and the remainder remained inpatient. Conclusion These findings underscore the need for better advance care planning, potentially improving patient management and reducing the emotional burden on patients, healthcare providers and families during critical moments.

Subjective performance assessment protocol for visual explanations-based face verification explainability

The integration of Face Verification (FV) systems into multiple critical moments of daily life has become increasingly prevalent, raising concerns regarding the transparency and reliability of these systems. Consequently, there is a growing need for FV explainability tools to provide insights into the behavior of these systems. FV explainability tools that generate visual explanations, e.g., saliency maps, heatmaps, contour-based visualization maps, and face segmentation maps, show promise in enhancing FV transparency by highlighting the contributions of different face regions to the FV decision-making process. However, evaluating the performance of such explainability tools remains challenging due to the lack of standardized assessment metrics and protocols. In this context, this paper proposes a subjective performance assessment protocol for evaluating the explainability performance of visual explanation-based FV explainability tools through pairwise comparisons of their explanation outputs. The proposed protocol encompasses a set of key specifications designed to efficiently collect the subjects’ preferences and estimate explainability performance scores, facilitating the relative assessment of the explainability tools. This protocol aims to address the current gap in evaluating the effectiveness of visual explanation-based FV explainability tools, providing a structured approach for assessing their performance and comparing with alternative tools. The proposed protocol is exercised and validated through an experiment conducted using two distinct heatmap-based FV explainability tools, notably FV-RISE and CorrRISE, taken as examples of visual explanation-based explainability tools, considering the various types of FV decisions, i.e., True Acceptance (TA), False Acceptance (FA), True Rejection (TR), and False Rejection (FR). A group of subjects with variety in age, gender, and ethnicity was tasked to express their preferences regarding the heatmap-based explanations generated by the two selected explainability tools. The subject preferences were collected and statistically processed to derive quantifiable scores, expressing the relative explainability performance of the assessed tools. The experimental results revealed that both assessed explainability tools exhibit comparable explainability performance for FA, TR, and FR decisions with CorrRISE performing slightly better than FV-RISE for TA decisions.

Causal network linking honey bee (Apis mellifera) winter mortality to temperature variations and Varroa mite density

Winter season is a critical time for honey bees (Apis mellifera) colonies when individual mortalities may lead to total colony losses or diminish productivity in subsequent seasons. A deeper understanding of the causes and consequences of winter mortality is required. In this study, we analyzed winter (November–March) individual bee mortality in an apiary in Central Europe from 1991 to 2023. We observed consistency in mortality times among years, but also some systematic departures from the shared trend. We distinguished four clusters of year-specific mortality trajectories. However, we found no statistically significant differences in means of spring (March–May), autumn (October), winter (November–March) temperatures, or autumn Varroa destructor density among clusters. Nevertheless, our insights into the dynamics of individual bee mortality may be important for determining critical moments during wintering when implementing additional protective measures could prove beneficial. Hypothesis-driven path analysis indicated causal links in our study system, including both direct and indirect influences. The density of V. destructor in autumn was positively related to temperature, especially in the preceding spring, but to a lesser extent also in autumn. Increased winter mortality was related to lower winter temperatures and a higher mite infestation in autumn. We found no significant effects of individual winter mortality on honey harvests in subsequent seasons. Honey harvest was determined by bee abundance in spring, and the latter, unexpectedly, was not related to winter mortality. Our study adds to accumulating evidence of the major role of weather and climatic conditions in the resilience of honey bee colonies and improves our understanding of mortality processes. We highlighted the importance of causative factors, especially seasonal temperatures and V. destructor density, and their potential as predictive indicators of individual winter mortality, bee colony fate, and honey productivity.

Predictors of Verbal Fluency Decline in People with Cognitive Dysfunctions

Background: Verbal fluency impairment is a prospective risk for dementia and conversion from Mild Cognitive Impairment (MCI) to dementia. In elderly may be related to the deficits in other cognitive domains and also with age and duration of cognitive decline. The AIM: The purpose of this study was to analyze the results of Verbal Fluency Tests (VFT) in people with cognitive decline in relation to age, duration of the cognitive decline and the level of cognitive dysfunction. Methods: 279 (177 females and 102 males) people with cognitive decline (MCI and dementia), aged 50-91 years were included in the study. For the evaluation of general cognitive abilities Mini Mental State Examination (MMSE) and for assessment of verbal fluency– Verbal Fluency Test (phonological and categorical) was applied. Statistical analysis was performed using nonparametric tests. Factor analysis of the main components of Verbal Fluency Test and MMSE were used and one-way ANOVA test in the prediction analysis was applied. Results: All dimensions of verbal fluency subscales and MMSE are explained by one factor, which indicate their similar etiological mechanism. The longer duration of the cognitive impairment the worse results in VFT and MMSE. Worse results of MMSE were associated with worse performance on VFT, the most important critical moment of deterioration was associated with scores in the range of 25-23 and 17-18 MMSE points, however there are some differences between verbal fluency categories. The most significant periods of duration of the disease for VFT performance were months 6 and 9, and for the category of categorical fluency months 6,9, as well as 26, 31-32 and 36. No significant associations between the age and VFT and MMSE results were observed. Conclusions: Verbal fluency decline is related to global cognitive functioning. Longer duration time of the disease was associated with the level of verbal fluency and cognitive decline, while the age of patients is not an important factor. The verbal fluency deterioration occurs in leaps and bounds, the critical moments for verbal fluency decline may be established based on the duration of the illness and global functioning measured by MMSE.

Contextualising Australia’s Role in UN Peacekeeping Operations: A Comprehensive Analysis from 1947 to Present

Purpose: This scholarly article rigorously analyses Australia’s engagement in United Nations (UN) peacekeeping operations from 1947 to the present, focusing on the nation's substantial contributions, significant policy transitions, and the broader implications for international relations and global governance frameworks. Materials and Methods: Utilizing a qualitative methodological approach, this study systematically reviews over sixty peacekeeping missions involving Australia, drawing upon a diverse array of primary and secondary sources, including governmental reports, academic journals, and UN documentation. The timeframe spans critical historical moments, beginning with Australia’s initial involvement in international peacekeeping initiatives in the late 1940s and evolving through distinct geopolitical eras, including the Cold War, post-Cold War period, and contemporary conflicts (Baldwin et al., 2022; McDonald, 2023). The analysis is grounded in a constructivist framework intertwined with realism, allowing for a nuanced understanding of how Australia’s peacekeeping roles reflect and reinforce the interplay of national interests and international obligations. This theoretical lens facilitates an exploration of the changing nature of global conflicts, operational mandates, and evolving international norms (Kirton, 2023). Findings: The research reveals that Australia’s peacekeeping contributions have evolved significantly, marked by key policy shifts from unilateralism to multilateralism within the UN paradigm. The country’s notable involvements in critical missions, such as those in East Timor and the Solomon Islands, exemplify its commitment to regional stability while also reflecting strategic partnerships with key allies (Cousens & Kumar, 2022). Furthermore, these contributions highlight Australia’s capacity to respond to complex emergencies and humanitarian crises effectively, reinforcing its role as a key player in regional peace and security. Implications to Theory, Practice and Policy: This examination elucidates the implications of Australia’s peacekeeping operations for its foreign policy trajectory and international standing. As the nation grapples with contemporary security challenges - including humanitarian crises, intrastate conflict, and post-colonial nation-building - the analysis reveals that Australia’s peacekeeping engagements align with broader international relations trends. Notably, there is an increasing emphasis on multilateralism, the principle of state sovereignty, and collaborative security efforts among nations (Hawkins, 2023).

Codicology and the Transformation of Islamic Law

Abstract In Islamic law, preponderance (tarjīḥ)—a practical method for mujtahids to resolve legal contradictions (taʿāruḍ) between proofs—has been known in the uṣūl tradition from at least the 10th-century jurist al-Jaṣṣāṣ (d. 370/981). Yet, it is in several 17th and 18th-century Arabic and Ottoman manuscripts of Princeton’s Garrett Collection that we encounter summary-like lists labelled “tarjīḥāt al-bayyināt” (“TB s”), which succinctly compile the complex rules of preponderance. Organized into three-columned lists, on loose leaves, as annotations in the margin or separate textual units, the TB s follow a grammatical and visual layout that made them predictable and recognizable for manuscript readers. This paper examines the TB s as a codicological phenomenon, arguing that they served as a shorthand for legal practitioners familiar with evidentiary law and that their presence suggests a broader transformative process of readers’/legal practitioners’ relationship with codices of positive law at this critical moment in the history of Islamic law.

Effect of loose sand layers within dense sand on the lateral capacity of extra-extra-large monopiles

A series of 3D finite element analyses were performed to examine the influence of loose sand layers on the monotonic lateral capacity of an extra-extra-large semirigid monopile in dense sand. The SANISAND-04 advanced constitutive model, which was meticulously calibrated, validated and verified using triaxial compression tests, centrifuge tests and a numerical study based on field tests, was adopted for this study. The impact of loose sand layers on monopile response is discussed in terms of its mode of deformation, critical lateral capacity, bending moment, shear force and soil resistance. Results show that the magnitude of the reduction in the monopile lateral capacity is dependent on the thickness and depth of the loose sand layer. Presence of loose sand at the tip of the monopile is also shown to have a significant effect on its lateral capacity.

Численность населения Республики Коми: от переписи населения 1897 г. к переписи населения 2021 г.

This article examines the population censuses conducted in the Russian Empire, the USSR and the new Russia; it reveals the peculiarities and methodological apparatus of each population census, presents the main questions of census lists, their comparability with previous censuses, notes new questions and explains their application. Thus, in the 2010 population census, the term “household” was introduced in the question on kinship (property) with other persons living with the respondent; in the question on marriage status, the concepts “officially divorced” and “separated” were differentiated; the levels of education and the presence of a degree were highlighted; the results of population censuses are given according to statistical data for the Komi Republic. The results of the population censuses of 1939 and 1959, which made it possible to assess the scale of forced migration to the Komi region, are separately considered. For each population census, the timing of its conduction and the critical moment are given, it is explained why certain population censuses were carried out not in the “zero” year, as is customary in most countries of the world, but in other years. Particular attention is paid to the 2021 census, it has been postponed for one year due to the COVID-19 pandemic.

From challenge to innovation: A grassroots study of teachers’ classroom assessment innovations

AbstractWe are at a critical moment for assessment in schools. Teachers are called to navigate advances in classroom assessment research, top‐down assessment policies, and lingering effects of the COVID‐19 pandemic on teaching and learning. Embedded in this context are also systemic challenges to teachers’ assessment practice. This paper analyses these challenges to characterise the current context for teachers’ assessment work and considers teachers’ innovative responses to these challenges. Data are drawn from 168 qualitative responses to a baseline assessment innovation survey across 10 Canadian provinces and territories as well as 10 other international jurisdictions. Eight themes were identified related to teachers’ assessment challenges and innovations, including: negating innovation, the emotions of assessment, grade obsession and the gradeless spectrum, conflicting orientations towards assessment, the use of ‘assessment talk’, data overload, equitable assessment and actions that make learning and assessment visible. These findings directly support the widespread goal of implementing assessments that effectively and consistently serve student learning. The paper concludes with a discussion on how teachers move from facing assessment challenges to engaging in assessment innovations.
