The School-to-Prison Pipeline: Using Mindfulness as an Alternative to Exclusionary Discipline Practices
Creators: name: Morrison, Maggie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Since the implementation of zero tolerance policies, school suspensions have significantly increased, particularly for students of color. The likelihood of a student entering the criminal system once they are forced out of school also has risen dramatically, forming a system that is now referred to as the School-to-Prison Pipeline. The purpose of this study was to look at alternative methods to exclusionary discipline practices like suspension. The focus of this study was on the implementation of mindfulness techniques in one elementary school. Existing literature established that mindfulness techniques can be beneficial for student’s academic, behavioral, and emotional outcomes. This study expanded on the existing literature through interviews with school personnel, who included the principal, school counselor, and a teacher. The teacher also was the parent of a child who was part of the school’s mindfulness program. Additionally, the study included an observation of a mindfulness lesson at the school. The participants in this study shared their beliefs that when mindfulness techniques were implemented in this school, they found students are empowered and engaged, gain life skills, and are better able to regulate their emotions. The results also showed that mindfulness can easily be implemented, as the core components align with essential standards that school counselors are required to follow. Interviewees suggested strengthening the program by collaborating more with teachers to use mindfulness techniques as part of the daily routine in their classrooms. It is suggested that future research should be conducted to find out more about how mindfulness can be incorporated in schools, but the results of the current study have implications for the field demonstrating that mindfulness has positive benefits for elementary students.

description: In higher education, about 60-70% of students use learning strategies (such as highlighting and summarizing) that are not effective for long term learning (Bjork, Dunlosky, & Kornell, 2013). Students tend to avoid effective learning strategies because these strategies cost high initial mental effort and provide no immediate learning gains (Kirk Johnson, Galla, & Fraundorf, 2009). With this study, we dissect students’ learning strategy decisions by investigating the role of their subjective learning experiences: mental effort and judgments of learning (JOL) and perceived effectiveness of learning strategies.
Preparing To Use Resonant Acoustic Spectroscopy with Optical Vibrometry to Characterize the Clot Elastic Modulus from Mice with Sickle Cell Disease
Creators: name: Segerstrom, Kara J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: CEMport is machine that uses resonant acoustic spectroscopy with optical vibrometry to find
the clot elastic modulus. In order to prepare CEMport for future experiments on sickle cell
disease, CEMport will be calibrated. The device was previously calibrated to a 150μL cube
microwell, but the following study will calibrate CEMport to a 100 μL cylindrical microwell.
Microwells with sample sizes 150μL, 125μL and 100μL were tested, and the results
demonstrated that all three sizes were able to produce quality fits. The sickle cell blood clots will
be formed from mice, therefore the reduction of sample size will allow more samples to be
created. The calibration coefficient a[0] in the equation: 𝐸 = 𝑎[0]𝜌𝑓[0]2, was found to be 0.063±0.002
Pa/Hz2, whereas the previously found ratio was 0.076±0.003 Pa/Hz2. Preliminary testing of
blood clots for human and mouse whole blood was 1.94±0.03kPa and 2.98±.33kPa
respectively, falling within the expected range of elasticity.
Unorthodox Hacking: Addressing Sexism in Hacktivist Communities to Expand Options for Electronic Civil Disobedience
Creators: name: Curcelli, Giulia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: With the proliferation of the computer over the past few decades, hacktivism—a
form of activism through computer hacking—has become widespread on the international
political stage, a critical aspect of cybersecurity, and an emerging question of the balance
between free expression and national security. Public perception often frames hacktivists
as malevolent practical jokers, but discourse is shifting to mirror hacktivists’ perceptions
of themselves as fighters for justice and an open internet. Because cyberspace remains
fresh and relatively legally unregulated, the constraints for this political participation
continue to evolve.
A subset of hacktivism is electronic civil disobedience. Academics have formed
various frameworks for the translation of traditional civil disobedience to the cyber
realm, viewing civil disobedience as an acceptable and healthy element of democracy. In
contrast, the security industry largely derides hacktivism as wholly threatening.
Academics have also begun to explore the links between gender and hacktivism,
acknowledging the male hacker archetype and the disproportionately low number of
women involved in hacking and technology.
Building on existing frameworks for the translation of civil disobedience to the
cyber realm, this analysis of electronic civil disobedience centers around three case
studies that illustrate different types of and perspectives on ECD. In particular, I examine
how the subjects of each case study do and do not talk about and experience gender, and
how this influences their understanding of hacking and what should be considered
electronic civil disobedience. This research bridges the gap between existing work on
when hacktivism is electronic civil disobedience and the influence of gender on
hacktivism. Currently, the views of hacking communities and legal professionals on what
constitutes acceptable civil disobedience are fundamentally misaligned. What hackers see
as legitimate, law enforcement sees as criminal. What law enforcement sees as acceptable
civil disobedience, hackers do not see as hacking. Ultimately, I argue that electronic civil
disobedience has more potential than its current use, but to increase its prevalence would
require a shift in perspective by both government and practitioners of civil disobedience.
The government does not distinguish between criminal and activist hacking but must
begin to do so to treat electronic civil disobedience as true civil disobedience, affording
sentences accordingly. On the part of hackers in particular, their perspectives are limited
by their gendered view of technology, and dismantling sexism and patriarchy in tech
communities will aid in this perspective shift.

description: The spin field effect transistor envisioned by Datta and Das opens a gateway to spin information processing. Although the coherent manipulation of electron spins in semiconductors is now possible, the realization of a functional spin field effect transistor for information processing has yet to be achieved, owing to several fundamental challenges such as the low spin-injection efficiency due to resistance mismatch, spin relaxation, and the spread of spin precession angles. Alternative spin transistor designs have therefore been proposed, but these differ from the field effect transistor concept and require the use of optical or magnetic elements, which pose difficulties for the incorporation into integrated circuits. Here, we present an all-electric and all-semiconductor spin field effect transistor, in which these obstacles are overcome by employing two quantum point contacts as spin injectors and detectors. Distinct engineering architectures of spin-orbit coupling are exploited for the quantum point contacts and the central semiconductor channel to achieve complete control of the electron spins -- spin injection, manipulation, and detection -- in a purely electrical manner. Such a device is compatible with large-scale integration and hold promise for future spintronic devices for information processing.

A Study of Art Integration at an Inner City Magnet Arts-Integrated Elementary School
Creators: name: Godat, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: The purpose of the study was to determine which of the four types of art integration described by Giles and Frego (2004) are used within the school and in what ways, as well as the perceived benefits and limitations of using art integration according to teachers and faculty at the school. Participants were teachers recruited from an inner-city art integrated magnet elementary school utilizing the Dillman (2000) Total Survey Design Method, which allowed for five emails asking for voluntary participation to be sent to every teacher at the school. Twelve teachers responded to a survey, which included educational history, demographics, and May & Robinson’s (2015) 12-item scale regarding perception of art integration. In addition, a dance and a music specials class were observed to determine the types of art integration used within the classroom. The teachers of these two classes were also interviewed to further determine perceptions of the benefits and limitations of art integration. Examples of affective, subservient, and social art integration are present within the specials classrooms at the school and there was evidence of co-equal art integration, but there were not complete examples of this form of art integration. The main perceived benefits of art integration determined were a lack of time for collaboration and a lack of preparedness for classroom teachers to integrate the art. The main perceived limitations of art integration determined were promotion of an inclusive and active learning environment and a deeper understanding of material.

description: Recent studies suggest that an exemplary Kondo insulator SmB6 belongs to a new class of topological insulators (TIs), in which non-trivial spin-polarized metallic states emerge on surface upon the formation of Kondo hybridization gap in the bulk. Remarkably, the bulk resistivity reaches more than 20 Ohm cm at 4 K, making SmB6 a candidate for a so-called bulk-insulating TI. We here investigate optical-pulse responses of SmB6 by pump-and-probe photoemission spectroscopy. Surface photovoltage effect is observed below ~90 K. This indicates that an optically-active band bending region develops beneath the novel metallic surface upon the bulk-gap evolution. The photovoltaic effect persists for >200 microsec, which is long enough to be detected by electronics devices, and could be utilized for optical gating of the novel metallic surface.
Time, Space, and Capital: Walter Benjamin in Apollinaire's "Zone" and Clair's Paris qui dort
Creators: name: Clark, Andrew
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: From the Exposition Universelle of 1889 to the aftermath of the Great War, Paris
witnessed the promise and horror of a mechanized future, enduring a fundamental upheaval in
the nature of urban experience. Developments in engineering which drove the construction of the
Eiffel tower and the first airplanes also brought the machine gun and mustard gas, and
production advancements which brought new standards of material well-being expanded
consumer culture, promulgated financial speculation, and strengthened means of economic
exploitation. Commodification and industrialization permeated deep into the lifeworld by the
turn of the century, altering the dynamics of life and thought. While global time became
standardized, individual experience was marked by shock, stimulus, and discontinuity.
Traditional spatial hierarchies were leveled as well. Spiritually, the Church ceded power in the
face of secularization and physically, limits on human elevation were surpassed through aviation,
architecture, and film technology.
Guillaume Apollinaire’s “Zone”, often held as the quintessential modernist poem, and
René Clair’s lesser studied 1924 film Paris qui dort exemplify this transformation in life and
thought in early twentieth century Paris. Both works examine the fragmented rhythm of modern
life through non-linear, personal temporalities. Images of the old and new world are juxtaposed
as Clair and Apollinaire study the dynamics of urbanization in Paris, most notably the formidable
presence of the Eiffel tower. This project studies the treatment of urban dynamics in Clair’s film
and Apollinaire’s poem through a discussion of the writings of Walter Benjamin, focusing on
how Benjamin’s formulations of experience, time in hell, bourgeois life, and utopian dreams can
be found in and understood through these two works, ultimately leading to an understanding of
the tension between liberation and domination which defines modern development...
Monotone Riemannian metrics and dynamic structure factor in condensed matter physics

description: An analytical approach is developed to the problem of computation of monotone Riemannian metrics (e.g. Bogoliubov-Kubo-Mori, Bures, Chernoff, etc.) on the set of quantum states. The obtained expressions originate from the Morozova, Chencov and Petz correspondence of monotone metrics to operator monotone functions. The used mathematical technique provides analytical expansions in terms of the thermodynamic mean values of iterated (nested) commutators of a model Hamiltonian T with the operator S involved through the control parameter $h$. Due to the sum rules for the frequency moments of the dynamic structure factor new presentations for the monotone Riemannian metrics are obtained. Particularly, relations between any monotone Riemannian metric and the usual thermodynamic susceptibility or the variance of the operator $S$ are discussed. If the symmetry properties of the Hamiltonian are given in terms of generators of some Lie algebra, the obtained expansions may be evaluated in a closed form. These issues are tested on a class of model systems studied in condensed matter physics.

description: Background Meatpacking plants were major sources of COVID-19 outbreaks, posing unprecedented risks to employees, family members, and local communities. The effect on food availability during outbreaks was immediate and staggering: within 2 months, the price of beef increased by almost 7% with documented evidence of significant meat shortages. Meatpacking plant designs, in general, optimize on production; this design approach constrains the ability to enhance worker respiratory protection without reducing output. Methods Using agent-based modeling, we simulate the spread of COVID-19 within a typical meatpacking plant design under varying levels of mitigation measures, including combinations of social distancing and masking interventions. Results Simulations show an average infection rate of close to 99% with no mitigation, 99% with the policies that US companies ultimately adopted, 81% infected with the combination of surgical masks and distancing policies, and 71% infected with N95 masks and distancing. Estimated infection rates were high, reflecting the duration and exertion of the processing activities and lack of fresh airflow in an enclosed space. Conclusion Our results are consistent with anecdotal findings in a recent congressional report, and are much higher than US industry has reported. Our results suggest current processing plant designs made rapid transmission of the virus during the pandemic's early days almost inevitable, and implemented worker protections during COVID-19 did not significantly affect the spread of the virus. We argue current federal policies and regulations are insufficient to ensure the health and safety of workers, creating a justice issue, and jeopardizing food availability in a future pandemic.
207.2 Digital Preservation in Contemporary Visual Art Workflows.

Subjects: subject: 207. Digital art preservation (paper presentations - chair: Jo Ana Morfin)
subject: ipres2018
subject: long paper

description: Effective seeking, management, preservation and distribution of digital data objects are critical to successful and sustainable performance in a range of contemporary professions and research domains. The contemporary visual artist operates in a professional domain that is explicitly comprised of research, experimentation, documentation and communication activities, but which takes place beyond the infrastructures of an institution, and beyond the reach of digital curation, digital preservation and research data management (RDM) policies, principles and advocacy. Additionally, the precarious economic position of the visual artist provides the opportunity to explore the strategies of digital object retrieval, management, preservation and re-use as they are developed and deployed by individuals with no particular digital curation or preservation training and with strictly limited resources. For both of these reasons, examination of the digital preservation practices of professional visual artists offers excellent potential for a particularly powerful case study with implications for the digital preservation community and the visual art sector alike. This paper describes ongoing qualitative research with a substantial sample of UK contemporary visual artists to understand their workflows, the value of digital tools and objects within these workflows, and artists’ current strategies for creating, retrieving, managing and preserving their digital objects. This study establishes that artists highly value their digital objects and rely on them for the critical tasks of creating and communicating their artwork. However despite the crucial role of digital object management, preservation and reuse, artists do not receive any instruction or guidance on these skills during their training. Findings suggest that filling this skills gap will provide artists with valuable skills that may significantly support the sustainability of their individual practices. Note: This paper is embargoed until the associated PhD research is completed and defended.
A Novel IgG Modified PEG-PEI Polyplex Formulation for Plasmid Delivery to the Brain

Year: 2017

description: Ischemic stroke can be associated with varying degrees of neuronal damage and death. To help combat the negative impact of cerebral ischemic events, research has turned its attention to the delivery of plasmids coding for key growth factors to improve neuronal survival. Delivery through the blood brain barrier, however, complicates drug delivery. The use of antibodies presents a unique opportunity to selectively target key receptors on the brain and gain access to this highly selective organ. In this study, a stable formulation for an antibody-conjugated polyplex system was established using polyethylene glycol-polyethylenimine copolymers complexed with plasmid DNA. These polyplexes offer the ability to deliver plasmid DNA through a self-assembling delivery system that has decreased clearance and selective localization to the brain. In establishing a foundation for such polyplexes, this study hopes to demonstrate the utility of this system in drug delivery to the brain.

description: Recycling the degraded graphite is becoming increasingly important, which can helped conserve natural resources, reduce waste, and provide economic and environmental benefits. However, current regeneration methods usually suffer from the use of harmful chemicals, high energy and time consumption, and poor scalability. Herein, we report a continuously high-temperature heating (≈2000 K) process to directly and rapidly upcycle degraded graphite containing impurities. A sloped carbon heater is designed to provide the continuous heating source, which enables robust control over the temperature profile, eliminating thermal barrier for heat transfer compared to conventional furnace heating. The upcycling process can be completed within 0.1 s when the degraded graphite rolls down the sloped heater, allowing us to produce the upcycled graphite on a large scale. High-temperature heating removes impurities and enhances the graphitization degree and (002) interlayer spacing, making the upcycled graphite more suitable for lithium intercalation and deintercalation. The assembled upcycled graphite||Li cell displays a high reversible capacity of ≈320 mAh g−1 at 1 C with a capacity retention of 96% after 500 cycles, comparable to current state-of-the-art recycled graphite. The method is a chemical-free, rapid, and scalable way to upcycle degraded graphite, and is adaptable to recycle other electrode materials.

Health Shocks and Retirement Timing in Latin America

Year: 2016

description: In this paper, I analyze the health and demographic factors that influence the timing of retirement. I use pooled data from six Latin American countries and investigate cross-country variations in retirement age and response to health shocks. I examine the effects of heart attacks, strokes, and cancer as well as two measures of overall health status on the population as a whole, divided based on demographic characteristics, and before and after nationwide pension reforms. I make use of childhood events and characteristics as instrumental variables to attempt to control for the endogeneity of health shocks in my model. I find that heart attacks, strokes, and cancer diagnoses have a strong effect on the retirement hazard that varies little across demographic groups.

description: The spatial and orientational distribution in a dilute active suspension of non-Brownian run-and-tumble spherical swimmers confined between two planar hard walls is calculated theoretically. Using a kinetic model based on coupled bulk/surface probability density functions, we demonstrate the existence of a concentration wall boundary layer with thickness scaling with the run length, the absence of polarization throughout the channel, and the presence of sharp discontinuities in the bulk orientation distribution in the neighborhood of orientations parallel to the wall in the near-wall region. Our model is also applied to calculate the swim pressure in the system, which approaches the previously proposed ideal-gas behavior in wide channels but is found to decrease in narrow channels as a result of confinement. Monte-Carlo simulations are also performed for validation and show excellent quantitative agreement with our theoretical predictions.
Do Conditional Cash Transfers Reduce Fertility? Nationwide Evidence from Mexico

Publisher: name: Wiley
Year: 2023

description: Conditional cash transfer (CCT) programs, which link transfers to investment in human capital in poor families, have spread around the world over the past two decades. This paper studies the medium-term effects of Progresa, the pioneering Mexican CCT program, on fertility using nationwide vital statistics combined with administrative data on program receipt. The effects of CCTs are likely to vary by age of the woman, and we study impacts by five-year age intervals. We test and account for possible underreporting of births using indirect methods. We find that Progresa led to an important and statistically significant decline in teenage fertility and smaller, but still significant, effects on reducing the fertility of older women.

description: We show that the frequency distribution of the first significant digits of the numbers in the data sets generated from a large class of measures of quantum correlations, which are either entanglement measures, or belong to the information-theoretic paradigm, exhibit a universal behaviour. In particular, for Haar uniformly simulated arbitrary two-qubit states, we find that the first-digit distribution corresponding to a collection of chosen computable quantum correlation quantifiers tend to follow the first-digit law, known as the Benford's law, when the rank of the states increases. Considering a two-qubit state which is obtained from a system governed by paradigmatic spin Hamiltonians, namely, the XY model in a transverse field, and the XXZ model, we show that entanglement as well as information theoretic measures violate the Benford's law. We quantitatively discuss the violation of the Benford's law by using a violation parameter, and demonstrate that the violation parameter can signal quantum phase transitions occurring in these models. We also comment on the universality of the statistics of first significant digits corresponding to appropriate measures of quantum correlations in the case of multipartite systems as well as systems in higher dimensions.

suppressors of cytokine signaling

description: Macrophages modulate the wound healing cascade by adopting different phenotypes such as pro-inflammatory (M1) or pro-wound healing (M2). To reduce M1 activation, the JAK/STAT pathway can be targeted by using suppressors of cytokine signaling (SOCS1) proteins. Recently a peptide mimicking the kinase inhibitory region (KIR) of SOCS1 has been utilized to manipulate the adaptive immune response. However, the utilization of SOCS1-KIR to reduce pro-inflammatory phenotype in macrophages is yet to be investigated in a biomaterial formulation. This study introduces a PEGDA hydrogel platform to investigate SOCS1-KIR as a macrophage phenotype manipulating peptide. Immunocytochemistry, cytokine secretion assays, and gene expression analysis for pro-inflammatory macrophage markers in 2D and 3D experiments demonstrate a reduction in M1 activation due to SOCS1-KIR treatment. The retention of SOCS1-KIR in the hydrogel through release assays and diffusion tests is demonstrated. The swelling ratio of the hydrogel also remains unaffected with the entrapment of SOCS1-KIR. This study elucidates how SOCS1-KIR peptide in PEGDA hydrogels can be utilized as an effective therapeutic for macrophage manipulation.
Hans Baldung Grien’s Reworking of Religious Motifs in His Early Career

description: Far removed from each other as these early works initially appear, they resonate thematically with one another in their apparent lack of concern for symbolically or theologically justifying their reworking of iconographic material --be it via the addition of a self-likeness, the parody of Dürer, or the disruption of standard formatting --and their formatting of audience response. Though only part of the story, taken together, the three offer compelling evidence that whatever his motives, Hans Baldung Grien sought to engage in novel ways of relating to religious images and themes, beyond their ostensibly devotional function, through formal choices that call attention that call attention to a complex reciprocal relationship: the editorial choice of the artist on the one hand, and on the other, the interpretative powers and responsibilities of the viewer.

description: Strain-induced deformations in graphene are predicted to give rise to large pseudomagnetic fields. We examine theoretically the case of gas-inflated bubbles to determine whether signatures of such fields are present in the local density of states. Sharp-edged bubbles are found to induce Friedel-type oscillations which can envelope pseudo-Landau level features in certain regions of the bubble. However, bubbles which minimise interference effects are also unsuitable for pseudo-Landau level formation due to more spatially varying field profiles.

description: In this study, we looked at the effect of promotion in the speed and width of spread of information on the Internet by tracking the diffusion of news articles over a social network. Speed of spread means the number of readers that the news has reached in a given time, while width of spread means how far the story has travelled from the news originator within the social network. After analyzing six stories in a 30-hour time span, we found out that the lifetime of a story's popularity among the members of the social network has three phases: Expansion, Front-page, and Saturation. Expansion phase starts when a story is published and the article spreads from a source node to nodes within a connected component of the social network. Front-page phase happens when a news aggregator promotes the story in its front page resulting to the story's faster rate of spread among the connected nodes while at the same time spreading the article to nodes outside the original connected component of the social network. Saturation phase is when the story ages and its rate of spread within the social network slows down, suggesting popularity saturation among the nodes. Within these three phases, we observed minimal changes on the width of information spread as suggested by relatively low increase of the width of the spread's diameter within the social network. We see that this paper provides the various stakeholders a first-hand empirical data for modeling, designing, and improving the current web-based services, specifically the IT educators for designing and improving academic curricula, and for improving the current web-enabled deployment of knowledge and online evaluation of skills.

description: Migration research tends to treat childrearing as a secondary role for migrants. By prioritising the economic objectives of migration, most models present migrants as either delaying childbearing or, if they have young children, not living with them. However, migration has become increasingly feminised, the types of mobility more varied, while the returns to migration remain uncertain at best. At the same time, norms around childrearing are shifting, and the capacity of kin to take care of children may be weakening. In such contexts, migrants may not want to or be able to be separated from their children. Confronting such difficult decisions and their consequences may be reflected in poor sleep health for the migrant parent. We draw on data from the Migration and Health Follow-Up Study (MHFUS) in South Africa to examine the following questions: (i) To what extent is children's coresidence associated with sleep health for migrant parents? (ii) Do effects vary by sex of migrant? and (iii) Do effects vary by location of migrant? Results from propensity score matching confirm that migrants who coreside with all their young children are more likely to experience healthy sleep compared to those who have nonresident or no young children. However, stratified analysis shows that these effects are only significant for women and those not living in Gauteng province. The value of these findings is underscored by the need for research on the well-being of migrant parents who are negotiating multiple agendas in economically precarious and physically insecure destinations.
Climate Induced Migration Policies in Atoll Island States

description: The effects of climate change are expected to be some of the biggest drivers of migration in the 21st century. However, the international system has yet to create a systemic response plan. Instead, they have suggested that nations handle climate-induced migration through national and bilateral policies. It would be expected that the nations most vulnerable to climate change, due to either geography or a lack of resources, would be the first to create a nationwide response. By examining four atoll island states (Kiribati, Tuvalu, the Maldives, and the Marshall Islands), I hope to better understand whether national policies are an appropriate solution to climate-induced migration.
Decolonizing anthropology

description: Thirty-two years after the publication of Faye V. Harrison's edited volume, Decolonizing Anthropology: Moving Further toward an Anthropology of Liberation, I take stock of the book's origins and its impact on the discipline. Despite intellectual barriers and postmodernist critiques, Decolonizing Anthropology has influenced a generation of anthropologists who carry forward the book's original spirit. Focusing on the third edition, I show that Decolonizing has both reflected and incited changes in the discipline. Finally, I turn to some recent work in which scholars continue to push the boundaries of what decolonizing anthropology can mean. Throughout, I emphasize the importance of decolonization as a practice in anthropology and highlight the ongoing struggles and successes of scholars working in this tradition.
Interatomic repulsion softness directly controls the fragility of supercooled metallic melts

description: We present an analytic scheme to connect the fragility and viscoelasticity of metallic glasses to the effective ion-ion interaction in the metal. This is achieved by an approximation of the short-range repulsive part of the interaction, combined with nonaffine lattice dynamics to obtain analytical expressions for the shear modulus, viscosity, and fragility in terms of the ion-ion interaction. By fitting the theoretical model to experimental data, we are able to link the steepness of the interionic repulsion to the Thomas-Fermi screened Coulomb repulsion and to the Born-Mayer valence-electron overlap repulsion for various alloys. The result is a simple closed-form expression for the fragility of the supercooled liquid metal in terms of few crucial atomic-scale interaction and anharmonicity parameters. In particular, a linear relationship is found between the fragility and the energy scales of both the screened Coulomb and the electron-overlap repulsions. This relationship opens up opportunities to fabricate alloys with tailored thermo-elasticity and fragility by rationally tuning the chemical composition of the alloy according to general principles. The analysis presented here brings a new way of looking at the link between the outer-shell electronic structure of metals and metalloids and the viscoelasticity and fragility thereof.

description: Lysyl oxidase (LOX) plays an important role in the elaboration of tendon mechanical properties during embryonic development by mediating enzymatic collagen crosslinking. We previously showed recombinant LOX (rLOX) treatment of developing tendon significantly increased LOX-mediated collagen crosslink density to enhance tendon mechanical properties at different stages of tissue formation. Working toward the future development of rLOX-based therapeutic strategies to enhance mechanical properties of tendons that are compromised, such as after injury or due to abnormal development, this study characterized the direct effects of rLOX treatment on embryonic tendon cells from different stages of tissue formation. Tendon cell morphology, proliferation rate, proliferative capacity, and metabolic activity were not affected by rLOX treatment. Tenogenic phenotype was stable with rLOX treatment, reflected by no change in cell morphology or tendon marker messenger RNA (mRNA) levels assessed by reverse-transcription polymerase chain reaction. Collagen mRNA levels also remained constant. Matrix metalloproteinase-9 expression levels were downregulated in later stage tendon cells, but not in earlier stage cells, whereas enzyme activity levels were undetected. Bone morphogenetic protein-1 (BMP-1) expression was upregulated in earlier stage tendon cells, but not in later stage cells. Furthermore, BMP-1 activity was unchanged when intracellular LOX enzyme activity levels were upregulated in both stage cells, suggesting exogenous rLOX may have entered the cells. Based on our data, rLOX treatment had minimal effects on tendon cell phenotype and behaviors. These findings will inform future development of LOX-focused treatments to enhance tendon mechanical properties without adverse effects on tendon cell phenotype and behaviors.

description: As professional science becomes increasingly computational, researchers and educators are advocating for the integration of computational thinking (CT) into science education. Researchers and policymakers have argued that CT learning opportunities should begin in elementary school and span across the K-12 grades. While researchers and policymakers have specified how students should engage in CT for science learning, the success of CT integration ultimately depends on how elementary teachers implement CT in their science lessons. This new demand for teachers who can integrate CT has created a need for effective conceptual tools that teacher educators and professional development designers can use to develop elementary teachers' understanding and operationalization of CT for their classrooms. However, existing frameworks for CT integration have limitations. Existing frameworks either overlook the elementary grades, conceptualize CT in isolation and not integrated into science, and/or have not been tested in teacher education contexts. After reviewing existing CT integration frameworks and detailing an important gap in the science teacher education literature, we present our framework for the integration of CT into elementary science education, with a special focus on how to use this framework with teachers. Situated within our design-based research study, we (a) explain the decision-making process of designing the framework; (b) describe the pedagogical affordances and challenges it provided as we implemented it with a cohort of pre- and in-service teachers; (c) provide suggestions for its use in teacher education contexts; and (d) theorize possible pathways to continue its refinement.
