PurposeExamine how social studies preservice teachers conceptualize and enact critical historical inquiry.Design/methodology/approachCritical qualitative case study.FindingsDiffering conceptual understandings and had trouble infusing their practice with the critical theory learned in the university.Originality/valueExamine how a core practice is bolstering the practice-theory connection in teacher education.

PurposeConversations around diversity, race and science fiction and fantasy films/television have sparked in response to recent casting decisions made in the upcoming live-action The Little Mermaid, The Lord of the Rings: The Rings of Power and Star Wars' Obi-Wan Kenobi (Deggans, 2022; Romano, 2022). Backlash against casting of actors of Color in these genres highlights racial projects where a cultural memory of whiteness comes up against multicultural change. The authors of this paper feel that there is great potential in using current-day racial issues around fantasy films/television to explore these racial projects with students in social studies classes (Omi and Winant, 2014).Design/methodology/approachUsing a qualitative textual analysis (Peräkylä, 2005), the authors examined online news media outlets addressing the casting of actors of Color in the aforementioned media pieces. After reviewing over twenty articles, the authors determined two major themes that would serve as the findings.FindingsIn this paper, themes of nostalgia for an imagined 'way things were' and future-based fears of how things will become emerged from the analysis, revealing a need for engaging students in the history of sci-fi and fantasy media, and the existing, diverse histories of storytelling featuring multiple races.Originality/valueThe authors argue that examining racial projects found in contemporary sci-fi and fantasy casting are chances for students to understand complex racial histories and how they blend into current-day cultural landscapes, and are opportunities to practice analysis of real-life racial histories and richly-imagined fantasy worlds, noticing how and why the two often collide when it comes to race.

States wishing to use force in the modern era frequently face strong incentives to exploit secrecy. Successful covert operations can reduce the likelihood of unwanted escalation with powerful rivals and help leaders conceal unpopular actions from domestic and foreign audiences alike. The many benefits of secrecy, however, can only be realized if covert operations remain covert. We argue that access to information and communications technologies (ICTs) is a critical factor that increases the chances that a covert mission will be exposed. As a result, leaders are much less likely to reach for the quiet option when a potential target has dense ICT networks. We illustrate our mechanism through US national security archival vignettes. We test our argument using a dataset of declassified US military and electoral interventions intended to subvert incumbent regimes throughout the Cold War. The core finding, that leaders are less likely to pursue covert action relative to alternative options when the chances of exposure are high, holds across five distinct measures of ICT networks as well as different model specifications and placebo tests. Our findings suggest that Cold War-style covert operations may well be a thing of the past in an age where communication and media technologies have proliferated to the far corners of the globe. We advance debates on communications technologies, covert action, and political violence.

Closure and reclamation of waste rock piles using engineered cover systems and water treatment of seepage is a common technique for management of acid rock drainage/metal leaching (ARD/ML) to mitigate adverse impacts to the receiving environment. Linking cover system performance (i.e. net percolation and/or oxygen ingress) to impacts to the receiving environment provides a rational basis for cover system design criteria. Two general models are used in the mining industry to predict long-term seepage and closure costs. One model assumes that loading of contaminants to the environment will remain unchanged under reduced flux rates (net percolation) where contaminant concentrations increase proportionally as a function of decreasing flow; the other assumes that a reduction in the flux rate will result in decreased contaminant loads for constant contaminant concentrations in flow. Both models will have a transition point at which reduced loading to the receiving environment will occur as the flux decreases. Enterprise Cape Breton Corporation implemented a program for the closure of historic coal mines located near Sydney, Nova Scotia, Canada, with Public Works and Government Services Canada providing project management. The Victoria Junction waste rock pile was reclaimed with an engineered cover system comprising a 60 mil HDPE geomembrane, a granular drainage layer and an overlying growth medium. It was estimated following closure that active treatment of seepage waters impacted by ARD/ML would be required for ~20 years before passive treatment systems could be established; however, this has occurred within seven years with significant cost savings realised. Reclamation of the site reduced the risk of potential loading under various failure scenarios. An acidity mass balance was used to provide an understanding of past (uncovered waste rock pile and active treatment), current (covered waste rock pile and passive treatment) and long-term (100 years) loading under progressive changes to water collection and treatment activities. The acidity mass balance will serve to inform management decisions in ongoing closure planning. The case study presented here demonstrates that it is possible to eliminate the need for active treatment of seepage for legacy sites. ; Non UBC ; Unreviewed ; Other

A wave of recent scholarship shows that the backgrounds of political leaders shape their behavior once in office. This paper shifts the literature in a new direction by investigating the conditions under which foreign observers think a leader's background is relevant. We argue that pre-tenure biographical attributes are most informative to outsiders during leadership transitions—unique periods where the new ruler does not yet have a track record—because a leader's background provides clues about how that leader might govern. But as time passes, foreign observers quickly discount the leader's biography and instead evaluate the leader's observable behavior. We test our theory by creating a systematic daily measure of attention to foreign leader backgrounds derived from the President's Daily Brief, a novel data source of 4991 recently declassified reports from the Central Intelligence Agency to the American president.

This qualitative case study examined five preservice social studies teachers (PSSTs) working in an urban teacher preparation program as they learned methods of critical historical inquiry (CHI). Moving from a critical multicultural citizenship education frame, CHI supports analysis of multiple perspectives and sources to construct equitable, justice-oriented understanding of the past on its own terms. Study results detail participant conceptual (mis)understandings with CHI, difficult histories, and historical perspective recognition limited their production of social studies curriculum aligned with critical multicultural citizenship education. Findings highlight the significance of preservice teacher epistemic cognition when learning CHI while also underscoring the importance of addressing preservice teacher historical positionality and political clarity when teaching CHI. In the absence of deeper conceptual understandings of CHI and a concomitant epistemic stance, PSSTs are unlikely to overcome institutional and political barriers or strategically navigate curricular constraints which increasingly block critical multicultural education in social studies classrooms ; Education

Protests and democratic transitions tend to spread cross-nationally. Is this true of all political events? We argue that the mechanisms underlying the diffusion of mass-participation events are unlikely to support the spread of elite-led violence, particularly coups. Further, past findings of coup contagion employed empirical techniques unable to distinguish clustering, common shocks, and actual diffusion. To investigate which events diffuse and where, we combine modern spatial dependence models with extreme bounds analysis (EBA). EBA allows for numerous modeling alternatives, including diffusion timing and the controls, and calculates the distribution of estimates across all combinations of these choices. We also examine various diffusion pathways, such as contagion among trade partners. Results from nearly 1.2 million models clearly undercut coup contagion. In comparison, we confirm that more mass-driven political events robustly spread cross-nationally. Our findings contribute to studies of political conflict and contagion, while introducing EBA as an effective tool for diffusion scholars.
