    Meek Mill’s life and career have been punctuated by trauma, from his childhood lived on the streets of Philadelphia, through his rise to fame and eventual arrival as one of hip hop’s household names. his 2018 track Trauma, Meek Mill describes, in revealing prose, just how the traumatic experiences he endured personally impacted and harmed him. He also embodies a role as narrator in describing the same traumas and harms that impact the daily lives of countless similarly situated young Black people in the United States. As a child, Mill’s lived experience was one of pervasive poverty and fear, as the world surrounding him consisted of large-scale poverty, addiction, crime, violence, and death. As a young man—at just 19 years of age—he was beaten by police, wrongfully arrested and incarcerated, and ultimately convicted of crimes that he did not commit, becoming another statistic as a young Black man swallowed by the American criminal justice system. Meek’s story, lyrics and contributions to hip hop illuminate the Black experience with law enforcement. His personal involvements provide a powerful narrative for exactly how a racially biased criminal justice system perpetrates a trauma that extends far greater than the law has traditionally recognized. This article highlights this narrative through the lens that Meek Mill provides because of his current prominence in hip hop and the importance of his narrative claims. Despite his success in achieving the status of a true hip hop icon, Meek Mill suffered the kind of childhood adversity and trauma that emerging health care research indicates leads to debilitating health outcomes in adulthood. Powerful health studies conducted over the past two decades have uncovered the startling impact of Adverse Childhood Experiences (“ACEs”). ACEs are traumatic events that occur in childhood, ranging from abuse and neglect to other traumatic experiences derived from household and community dysfunction. Today, ACEs are generally placed by health researchers into seven to ten categories of childhood adversities ranging from sexual, physical and emotional abuse to the incarceration of a family member, living with someone who abuses alcohol or drugs and poverty, community violence and homelessness. These identified categories of trauma, although not fully understood or grasped as late as the 1990s, were known to occur in the lives of children all over the United States; however, the overall impact of childhood trauma on an individual’s long term health outcomes was only first measured in the now famous CDC-Kaiser Permanente ACE study. The findings of this study shook the health care world, forever altering the understanding of the link between childhood trauma and adult health outcomes. These links pushed researchers to look more deeply into the ultimate impact of traumatic childhood experiences on overall adult health. The groundbreaking study concluded that the more trauma a child experiences, the fewer years that child would live as an adult. In fact, in a 2009 study, CDC researchers determined that exposure to childhood trauma literally shortens an individual’s lifespan. On average, a person with six or more ACEs died twenty years earlier than a person that had experienced no Adverse Childhood Experiences. This reality, that traumatic childhood experiences are directly and inextricably linked to negative health outcomes, is now widely recognized in the public health and clinical literature. Dr. Robert Block, former President of the American Academy of Pediatrics, has warned that “[a]dverse childhood experiences are the single greatest unaddressed public health threat facing our nation today.” More recently, this literature has begun to explore the connection between trauma and race, outlining how structural violence and historical trauma—particularly violence and discrimination experienced by Black, indigenous, and persons of color—is often experienced both at the individual and community levels. Such work has focused on improving economic opportunities for trauma- stricken communities, improving the physical/built environment, and supporting the development of healthy social-cultural environments. The prevailing framework for addressing the ACEs crisis has been a medical model focused on interventions for individual survivors and communities rather than addressing the glaring systemic issues that directly contribute to the vast majority of the trauma suffered by those communities and the individuals and families that inhabit them. Largely and undeniably absent from the body of work on childhood trauma, and the proposed solutions to confronting and rectifying its deadly impact, is the exploration of how the American legal and justice systems, from municipal law enforcement to the appellate courts, stands at the epicenter of the current crisis. Each of the recognized categories of ACEs listed in medical screening instruments used by physicians to identity trauma have a direct nexus to the justice system. If we as a society are committed to treating ACEs as the public health crisis that they are, it is incumbent upon us to examine where and how our legal system is complicit in perpetuating trauma upon minority children. In addition, we need to consider how it can intervene—both at the individual and structural levels—to eliminate practices that contribute to multi-generational cycles of trauma and work to equip those with justice-system involvement to succeed and build the resilience necessary to heal minority individuals and communities who have been stricken by trauma and its life-long negative consequences. Indeed it is the responsibility of our justice system, as a major contributor to so-called “social determinants of health.” Meek Mill, in his intimate autobiographical tracks of Trauma, Oodles O’Noodles Babies, and Otherside of America, describes experiencing not just several instances of childhood trauma as identified by the CDC-Kaiser Permanente study, but as a teenager, he suffered additional cruel trauma at the hands of U.S. police and a criminal justice system that wrongly imprisoned and unfairly positioned him in a revolving door between probation and prison. The data tells us that the trauma Meek experienced as a child and teenager statistically predicts a poorer life expectancy for him than those individuals that experienced no trauma or little trauma as a child and youth. Because of the anti-Black culture of policing in America, and because of the deep systemic racism that permeates the criminal justice system, simple exposure to U.S. policing and its courts should qualify as an Adverse Childhood Experience for Black and minority children—one that contributes to harmful adult outcomes, including a shortened life expectancy. Mill’s personal childhood trauma as described in his music carefully extrapolates the ways that American policing and the criminal justice system literally traumatized and endangered his young Black life, as it does so many Black children. This article begins in Section I by providing an in-depth examination of ACEs research, including how the groundbreaking original ACE study discovered the direct link between high ACE scores and poor health outcomes and the prevalence of ACEs in the Black community. It then turns, in Section II, to a brief discussion of the broad ACE category of social disadvantage, and how a child growing up in an environment built on a foundation of poverty and violence will inevitably have more trauma, more ACEs, and be harmed through his or her experience of toxic stress. Section III will provide an overview of anti-Black policing and how law enforcement, as currently constituted, traumatizes minority communities and youth. Section IV explains how criminal charging, jailing, and sentencing traditions have disproportionately targeted Black men, contributing to the trauma that their children and families experience with the loss of a loved one to death or incarceration. The article next argues that minority youth exposure to U.S. law enforcement agents and the justice system at large functions as an ACE for youth of color in a way that is simply not present for non-minority youth and, as such, should be added to the list of ACEs that are formally recognized by public health officials. Finally, the article concludes with how Meek Mill himself is seeking to reform a system rife with debilitating trauma. Throughout each section, Meek Mill, and the raw lyrics from some of his most personal tracks, will serve as an illustration, and example, of how social disadvantage, police misconduct and brutality, and the American criminal justice system at large, cause harmful and lifelong trauma for Black Americans

    Towards Correctness of Program Transformations Through Unification and Critical Pair Computation

    Get PDF
    Correctness of program transformations in extended lambda calculi with a contextual semantics is usually based on reasoning about the operational semantics which is a rewrite semantics. A successful approach to proving correctness is the combination of a context lemma with the computation of overlaps between program transformations and the reduction rules, and then of so-called complete sets of diagrams. The method is similar to the computation of critical pairs for the completion of term rewriting systems. We explore cases where the computation of these overlaps can be done in a first order way by variants of critical pair computation that use unification algorithms. As a case study we apply the method to a lambda calculus with recursive let-expressions and describe an effective unification algorithm to determine all overlaps of a set of transformations with all reduction rules. The unification algorithm employs many-sorted terms, the equational theory of left-commutativity modelling multi-sets, context variables of different kinds and a mechanism for compactly representing binding chains in recursive let-expressions.Comment: In Proceedings UNIF 2010, arXiv:1012.455

    Constrained TRPV1 agonists synthesized via silver-mediated intramolecular azo-methine ylide cycloaddition of α-iminoamides

    As part of an effort to identify agonists of TRPV1, a peripheral sensory nerve ion channel, high throughput screening of the NIH Small Molecule Repository (SMR) collection identified MLS002174161, a pentacyclic benzodiazepine. A synthesis effort was initiated that ultimately afforded racemic seco analogs 12 of the SMR compound via a silver mediated intramolecular [3+2] cycloaddition of an azo-methine ylide generated from α-iminoamides 11. The cycloaddition set four contiguous stereocenters and, in some cases, also spontaneously afforded imides 13 from 12. The synthesis of compounds 12, the features that facilitated the conversion of 12–13, and their partial agonist activity against TRPV1 are discussed

    L-functions with large analytic rank and abelian varieties with large algebraic rank over function fields

    Full text link
    The goal of this paper is to explain how a simple but apparently new fact of linear algebra together with the cohomological interpretation of L-functions allows one to produce many examples of L-functions over function fields vanishing to high order at the center point of their functional equation. The main application is that for every prime p and every integer g>0 there are absolutely simple abelian varieties of dimension g over Fp(t) for which the BSD conjecture holds and which have arbitrarily large rank.Comment: To appear in Inventiones Mathematica

    The Upper Respiratory Tract as a Microbial Source for Pulmonary Infections in Cystic Fibrosis. Parallels from Island Biogeography

    Get PDF
    A continuously mixed series of microbial communities inhabits various points of the respiratory tract, with community composition determined by distance from colonization sources, colonization rates, and extinction rates. Ecology and evolution theory developed in the context of biogeography is relevant to clinical microbiology and could reframe the interpretation of recent studies comparing communities from lung explant samples, sputum samples, and oropharyngeal swabs. We propose an island biogeography model of the microbial communities inhabiting different niches in human airways. Island biogeography as applied to communities separated by time and space is a useful parallel for exploring microbial colonization of healthy and diseased lungs, with the potential to inform our understanding of microbial community dynamics and the relevance of microbes detected in different sample types. In this perspective, we focus on the intermixed microbial communities inhabiting different regions of the airways of patients with cystic fibrosis

    International society of sports nutrition position stand: diets and body composition

    Full text link
    Position Statement: The International Society of Sports Nutrition (ISSN) bases the following position stand on a critical analysis of the literature regarding the effects of diet types (macronutrient composition; eating styles) and their influence on body composition. The ISSN has concluded the following. 1) There is a multitude of diet types and eating styles, whereby numerous subtypes fall under each major dietary archetype. 2) All body composition assessment methods have strengths and limitations. 3) Diets primarily focused on fat loss are driven by a sustained caloric deficit. The higher the baseline body fat level, the more aggressively the caloric deficit may be imposed. Slower rates of weight loss can better preserve lean mass (LM) in leaner subjects. 4) Diets focused primarily on accruing LM are driven by a sustained caloric surplus to facilitate anabolic processes and support increasing resistance-training demands. The composition and magnitude of the surplus, as well as training status of the subjects can influence the nature of the gains. 5) A wide range of dietary approaches (low-fat to low-carbohydrate/ketogenic, and all points between) can be similarly effective for improving body composition. 6) Increasing dietary protein to levels significantly beyond current recommendations for athletic populations may result in improved body composition. Higher protein intakes (2.3–3.1 g/ kg FFM) may be required to maximize muscle retention in lean, resistance-trained subjects under hypocaloric conditions. Emerging research on very high protein intakes (\u3e3 g/kg) has demonstrated that the known thermic, satiating, and LM-preserving effects of dietary protein might be amplified in resistance-training subjects. 7) The collective body of intermittent caloric restriction research demonstrates no significant advantage over daily caloric restriction for improving body composition. 8) The long-term success of a diet depends upon compliance and suppression or circumvention of mitigating factors such as adaptive thermogenesis. 9) There is a paucity of research on women and older populations, as well as a wide range of untapped permutations of feeding frequency and macronutrient distribution at various energetic balances combined with training. Behavioral and lifestyle modification strategies are still poorly researched areas of weight management

    Social-ecological connections across land, water, and sea demand a reprioritization of environmental management

    Get PDF
    Despite many sectors of society striving for sustainability in environmental management, humans often fail to identify and act on the connections and processes responsible for social-ecological tipping points. Part of the problem is the fracturing of environmental management and social-ecological research into ecosystem domains (land, freshwater, and sea), each with different scales and resolution of data acquisition and distinct management approaches. We present a perspective on the social-ecological connections across ecosystem domains that emphasize the need for management reprioritization to effectively connect these domains. We identify critical nexus points related to the drivers of tipping points, scales of governance, and the spatial and temporal dimensions of social-ecological processes. We combine real-world examples and a simple dynamic model to illustrate the implications of slow management responses to environmental impacts that traverse ecosystem domains. We end with guidance on management and research opportunities that arise from this cross-domain lens to foster greater opportunity to achieve environmental and sustainability goals.Peer reviewe
