Architecture for spacecraft operations planning

A system which generates plans for the dynamic environment of space operations is discussed. This system synthesizes plans by combining known operations under a set of physical, functional, and temperal constraints from various plan entities, which are modeled independently but combine in a flexible manner to suit dynamic planning needs. This independence allows the generation of a single plan source which can be compiled and applied to a variety of agents. The architecture blends elements of temperal logic, nonlinear planning, and object oriented constraint modeling to achieve its flexibility. This system was applied to the domain of the Intravehicular Activity (IVA) maintenance and repair aboard Space Station Freedom testbed

Disrupting the Path from Childhood Trauma to Juvenile Justice: An Upstream Health and Justice Approach

A groundbreaking public health study funded by the U.S. Centers for Disease Control and Prevention (CDC) and the Kaiser Foundation found astoundingly high rates of childhood trauma, including experiences like abuse, neglect, parental substance abuse, mental illness, and incarceration. Hundreds of follow-up studies have revealed that multiple traumatic adverse childhood experiences (or “ACEs”) make it far more likely that a person will have poor mental health outcomes in adulthood, such as higher rates of depression, anxiety, suicide attempts, and substance abuse. Interestingly, the original ACE Study examined a largely middle-class adult population living in San Diego, but subsequent follow-up studies have examined the prevalence of ACEs and its impact on mental health in other populations, including among people involved in the juvenile and criminal justice systems. Unsurprisingly, individuals entangled in those systems are more likely to have experienced higher numbers of these traumatic events, despite a frequent lack of access to critical mental health treatment, including the treatment necessary to address past childhood trauma. The ACEs framework for understanding health and mental health outcomes resulting from childhood trauma has received a high level of attention recently following an in-depth, multi-part series on these issues by National Public Radio (NPR) and other media. Because the ACEs public health research shows us that events in childhood can cause “toxic stress” and have a lasting impact on the mental health of a child well into adulthood, this framework provides us with an opportunity to consider how to more effectively intervene to stop the pathway from ACEs to juvenile justice system involvement and address the related health, mental health, developmental, and legal needs of children and their families. Before a child becomes an adult facing a mental health crisis or incarceration, attorneys, doctors, and other professionals can collaborate to disrupt that fate. This Article argues for a more upstream approach to address mental health using a medical-legal collaboration, based on the experiences of the authors, a law professor and medical school professor who work together to try to improve outcomes for children who have experienced trauma and their families. In Part I, we begin by examining the groundbreaking ACE studies, exploring the toxic stress and health and mental health outcomes that are associated with high rates of ACEs in childhood. Next, in Part II, we analyze the research revealing high rates of trauma and ACEs among populations involved in the juvenile justice system. Finally, we conclude in Part III by arguing for a more upstream public health and justice approach. We examine a particular problem in the city of Albuquerque, the largest urban area in New Mexico: children who have a particular ACE right from birth in the form of substance abuse by a household member. These infants are born with prenatal drug exposure and many experience symptoms of withdrawal in their first weeks of life, often quickly followed by an accumulation of additional forms of early childhood trauma. We discuss an approach through which the authors work to address those issues and disrupt the path from that childhood trauma to poor outcomes and juvenile justice system involvement. This approach engages attorneys with doctors and other health and developmental professionals to address ACEs among young children ages zero to three and their siblings, parents, and other caregivers. We advocate for an early, holistic, multi-generational, multi-disciplinary public health and justice approach to address ACEs early and improve the trajectory for children who have experienced childhood trauma

Travelers’ diarrhea and other gastrointestinal symptoms among Boston-area international travelers

INTRODUCTION: Travelers' diarrhea (TD) and non-TD gastrointestinal (GI) symptoms are common among international travelers. In a study of short-term travelers from Switzerland to developing countries, the most common symptom experienced was severe diarrhea (8.5%) followed by vomiting or abdominal cramps (4%).1 GI illnesses were the most frequently reported diagnoses (34%) among ill-returned travelers to GeoSentinel clinics.2 Of those returning to U.S. GeoSentinel clinics, acute diarrhea (30%) was the most common diagnosis.3 In one cohort of U.S. travelers, 46% reported diarrhea.4 GI illnesses can last from 2 days to weeks or longer,5 disrupting plans during travel or after returning home. Eighty percent of those who experienced diarrhea during travel treated themselves with medication and 6% sought medical care. METHODS: The Boston Area Travel Medicine Network (BATMN) is a research collaboration of travel clinics in the greater Boston area representing urban-, suburban-, academic-, and university-affiliated facilities. A convenience sample of travelers ≥ 18 years of age attending three BATMN clinics between 2009 and 2011 for pre-travel consultations completed pre-travel surveys, at least one survey weekly during travel, and a post-travel survey 2–4 weeks after return. Travelers were asked to complete a survey at the end of each week of their trip. Institutional review board approvals were obtained at all sites and the Centers for Disease Control and Prevention, and participants provided written informed consent. Information collected included demographic and trip characteristics, vaccines and medications recommended/prescribed before travel, medications taken during travel, dietary practices during travel (consumption of tap water, ice in drinks, unpasteurized dairy products, and salads), symptoms experienced, and impact of illness during and after travel. Vaccinations, prescriptions, and travel health advice given during the pre-travel consultation were recorded by a clinician, and the remainder of the surveys were completed by the traveler. Data were entered into a password-protected database (CS Pro, U.S. Census Bureau, Washington, DC). RESULTS: We enrolled 987 travelers; 628 (64%) completed all three parts (pre-, during, and post-travel) and were included in the study. Comparison of the 628 to the 359 who did not complete all three parts (noncompleters) revealed no differences, except that completion rates were higher for white travelers than all other racial/ethnic groups (P < 0.001) and for older travelers (median age 47 years versus 32 years in noncompleters, P < 0.001).11 Of those 628 travelers, 208 (33%) experienced TD, 45 (7%) experienced non-TD GI symptoms, 147 (23%) experienced non-GI symptoms, and 228 (36%) did not experience any symptoms during or after travel. Of the 208 with TD, 140 (67%) reported diarrhea as their only symptom, whereas 33 (16%) also experienced nausea/vomiting, 23 (11%) abdominal pain, and 27 (13%) fever (Table 1). Of the 45 who reported non-TD GI symptoms, 21 (47%) experienced nausea/vomiting, 19 (42%) experienced constipation, and 10 (22%) experienced abdominal pain during or after travel (Table 2). Almost all travelers (99%) received advice about food and water precautions and diarrhea management during pre-travel consultation

Boundary objects, power, and learning: The matter of developing sustainable practice in organizations

This article develops an understanding of the agential role of boundary objects in generating and politicizing learning in organizations, as it emerges from the entangled actions of humans and non-humans. We offer two empirical vignettes in which middle managers seek to develop more sustainable ways of working. Informed by Foucault’s writing on power, our work highlights how power relations enable and foreclose the affordances, or possibilities for action, associated with boundary objects. Our data demonstrate how this impacts the learning that emerges as boundary objects are configured and unraveled over time. In so doing, we illustrate how boundary objects are not fixed entities, but are mutable, relational, and politicized in nature. Connecting boundary objects to affordances within a Foucauldian perspective on power offers a more nuanced understanding of how ‘the material’ plays an agential role in consolidating and disrupting understandings in the accomplishment of learning

Experiences among undocumented migrants accessing primary care in the United Kingdom: a qualitative study.

Immigration is a key political issue in the United Kingdom. The 2014 Immigration Act includes a number of measures intended to reduce net immigration, including removing the right of non-European Economic Area migrants to access free health care. This change risks widening existing health and social inequalities. This study explored the experiences of undocumented migrants trying to access primary care in the United Kingdom, their perspectives on proposed access restrictions, and suggestions for policymakers. Semi-structured interviews were conducted with 16 undocumented migrants and four volunteer staff at a charity clinic in London. Inductive thematic analysis drew out major themes. Many undocumented migrants already faced challenges accessing primary care. None of the migrants interviewed said that they would be able to afford charges to access primary care and most said they would have to wait until they were much more unwell and access care through Accident & Emergency (A&E) services. The consequences of limiting access to primary care, including threats to individual and public health consequences and the additional burden on the National Health Service, need to be fully considered by policymakers. The authors argue that an evidence-based approach would avoid legislation that targets vulnerable groups and provides no obvious economic or societal benefit

Committee Size and Smart Growth: An Optimal Solution

Wisconsin is one of many states that have enacted a “Smart Growth Initiative” law that requires inclusion of the public in the creation and development of a Comprehensive Plan. One implication of public participation is the strategic development of a comprehensive planning committee. Two crucial decisions occur when the committee is formed: the size of the committee and the composition of the committee. This paper models a relation between committee size and the accuracy of plan, as well as the relationship between the inclusion of experts, whether paid consultants or planners, and the quality of the outcome. Based on a survey of committee members, we test the relationship between the participants’ observations of quality and group size and composition, analyzing the tradeoff between the size of the group with the perception of quality of the decision
