Unlocking Classroom Discourse: Supporting Early Career Teachers in Their Development of Culturally Inclusive Social-Emotional Teaching Practices

This Improvement Science research study investigates how school districts can support educators with one to three years of experience in developing culturally inclusive social-emotional teaching practices (CISEL). This mixed-methods study aimed to understand the early career teacher experience and their perspectives on CISEL to identify structures that support this area of pedagogical development during the transition from preparation to employment. First, an initial root cause analysis exposed the need for more explicit integration of cultural inclusivity into educator preparation and early career teacher professional learning in the state and district that employs the scholarly practitioner. Secondly, the root cause analysis confirmed that early career teachers perceive the social teaching practice of “responsibility and choice” as an area for growth. Combining these findings with a literature review on early career teacher support and culturally inclusive teaching practices, the researcher developed and implemented an intervention focused on classroom discourse. Classroom discourse is relevant to the development of CISEL because it relies on the teacher’s instructional choices to facilitate student voice, student choice, and student interaction. The research participants who volunteered for this study participated in two interviews, implemented a classroom discourse structure four times, and reflected on their implementation using a targeted rubric and questions. This study converged descriptive and correlational analyses from the rubric data with coded themes from the written reflections and interviews. Results show that teacher delivery correlates to student communication and interaction. Additionally, the use of targeted and explicit reflections on social-emotional teaching practices can offer teachers support in their development of culturally inclusive classroom practices. These findings lead the researcher to recommend policy changes that include explicit guidance for culturally inclusive teaching practices across teacher preparation, onboarding, and evaluation. The research findings also ask magnet districts to consider professional learning that is differentiated and collaborative based on the strengths of each unique school. This study recommends future research on student perceptions of CISEL and mentor awareness of CISEL-related practices and resources

Holding the High Ground: The Operational Calculus of Torture and Coercive Interrogation

In Part I of this Article, we first consider some of the strengths and weaknesses of the partially adequate objections. In Part II, we explore torture in light of the biological distinction between pain and suffering and consider the implications of that distinction for our understanding of free will and the fighting spirit. Finally, in Part III, we suggest a more fundamental view of torture that navigates between the Scylla of naive moralizing and the Charybdis of ticking time-bombs. We propose that the debate should focus on torture\u27s effect on our country\u27s moral certainty, on the fighting spirit of our armed forces, and on our overall strategy in combating asymmetric foes and jihadist extremism. This notion of torture will cast an important part of the discussion in sharper relief while providing a clearer norm for those who make and execute policy to defend our nation from terrorism

Hydraulic Computations for Stepped Concrete Overlays of Embankment Dams

One method for rehabilitating and modernizing embankment dams is the addition of a concrete overlay that protects the embankment and allows floods to pass safely over the dam. Roller compacted concrete is commonly used, which makes it practical to use a stepped construction that also enhances energy dissipation. Analysis of flow conditions over such structures requires computation of aerated flow and its effects on flow depth, training wall design, and energy dissipation. This paper describes Spillway Pro, an energy-based water surface profile calculation tool for smooth spillway chutes (Wahl et al. 2019), recently improved to also analyze stepped chutes. The tool is applicable to a wide range of chute slopes, including flatter slopes typical of embankment dam overlays and steeper slopes encountered on concrete gravity dams. An energy-based analysis allows Spillway Pro to be applied to situations differing from the idealized configurations covered by available empirical approaches, such as non-constant slopes, varying step heights, and converging chutes. Spillway Pro integrates water surface profile calculations, aerated flow effects, and cavitation analysis, which is potentially important for steeper slopes and large unit discharges. Simultaneous calculation of smooth and stepped-chute flow profiles enables rapid assessment of the energy dissipation benefits of steps, as well as a comparison of the aerated flow and cavitation issues for smooth vs. stepped chute alternatives

Automated Analysis of Fluorescence Microscopy Images to Identify Protein-Protein Interactions

The identification of protein interactions is important for elucidating biological networks. One obstacle in comprehensive interaction studies is the analyses of large datasets, particularly those containing images. Development of an automated system to analyze an image-based protein interaction dataset is needed. Such an analysis system is described here, to automatically extract features from fluorescence microscopy images obtained from a bacterial protein interaction assay. These features are used to relay quantitative values that aid in the automated scoring of positive interactions. Experimental observations indicate that identifying at least 50% positive cells in an image is sufficient to detect a protein interaction. Based on this criterion, the automated system presents 100% accuracy in detecting positive interactions for a dataset of 16 images. Algorithms were implemented using MATLAB and the software developed is available on request from the authors

fSpatial and temporal dynamics of cellulose degradation and biofilm formation by Caldicellulosiruptor obsidiansis and Clostridium thermocellum

Cellulose degradation is one of the major bottlenecks of a consolidated bioprocess that employs cellulolytic bacterial cells as catalysts to produce biofuels from cellulosic biomass. In this study, we investigated the spatial and temporal dynamics of cellulose degradation by Caldicellulosiruptfor obsidiansis, which does not produce cellulosomes, and Clostridium thermocellum, which does produce cellulosomes. Results showed that the degradation of either regenerated or natural cellulose was synchronized with biofilm formation, a process characterized by the formation and fusion of numerous crater-like depressions on the cellulose surface. In addition, the dynamics of biofilm formation were similar in both bacteria, regardless of cellulosome production. Only the areas of cellulose surface colonized by microbes were significantly degraded, highlighting the essential role of the cellulolytic biofilm in cellulose utilization. After initial attachment, the microbial biofilm structure remained thin, uniform and dense throughout the experiment. A cellular automaton model, constructed under the assumption that the attached cells divide and produce daughter cells that contribute to the hydrolysis of the adjacent cellulose, can largely simulate the observed process of biofilm formation and cellulose degradation. This study presents a model, based on direct observation, correlating cellulolytic biofilm formation with cellulose degradation
