Next generation software environments : principles, problems, and research directions

The past decade has seen a burgeoning of research and development in software environments. Conferences have been devoted to the topic of practical environments, journal papers produced, and commercial systems sold. Given all the activity, one might expect a great deal of consensus on issues, approaches, and techniques. This is not the case, however. Indeed, the term "environment" is still used in a variety of conflicting ways. Nevertheless substantial progress has been made and we are at least nearing consensus on many critical issues.The purpose of this paper is to characterize environments, describe several important principles that have emerged in the last decade or so, note current open problems, and describe some approaches to these problems, with particular emphasis on the activities of one large-scale research program, the Arcadia project. Consideration is also given to two related topics: empirical evaluation and technology transition. That is, how can environments and their constituents be evaluated, and how can new developments be moved effectively into the production sector

Emerging Perspectives on Children in Migratory Circumstances: Selected Proceedings of the Working Group on Childhood and Migration June 2008 Conference

The pieces you see in this e-book provide rich data from the lives of migrant children and sometimes their families. Chantal Tetreault’s piece among transnational Algerian teen girls in Paris and Kendall King’s study in Ecuador are linguistic in focus, bringing up the ways that performance in language is part of the practice of immigrant experience (Tetreault) and highlighting how regard for globalization and attention to language are deeply intertwined for immigrant communities (King). Most of the pieces provide in depth points of view from child migrant perspectives—data that is often difficult to obtain and portray sensitively. Child-centered data is exceptionally valuable in helping us to grasp the micro-forces by which childhood is changing through migration and how children experience or activate agency under trying conditions. Laure Bjawi-Levine among Palestinians in Jordan, Lauren Heidbrink among Spanish speakers in immigration detention in the U.S., and Jill White among Mexican children in U.S. labor and schooling environments demonstrate ways in which children’s self-understanding is constrained by state and economy in ways that determine a marked life course. Kanwal Mand’s also deeply child-centered analysis shows us how migrant childhoods can be notably shaped and sometimes constrained largely by urban housing and schooling environments, in this case for Pakistani second-generation children in London. Cati Coe’s interviews with informants in Ghana, and Catríona Ní Laoire’s study on return Irish migrants examine strains across the generations that affect the emotional management of families and individuals to handle the spatial and temporal challenges of migration. And finally, Michelle Moran-Taylor provides a rich analysis of the gendered and socioeconomic strategies that families use to negotiate the challenge of child-rearing in the home area when families are geographically separated, drawing especially on data from Guatemala

The Spread of Inequality

The causes of socioeconomic inequality have been debated since the time of Plato. Many reasons for the development of stratification have been proposed, from the need for hierarchical control over large-scale irrigation systems to the accumulation of small differences in wealth over time via inheritance processes. However, none of these explains how unequal societies came to completely displace egalitarian cultural norms over time. Our study models demographic consequences associated with the unequal distribution of resources in stratified societies. Agent-based simulation results show that in constant environments, unequal access to resources can be demographically destabilizing, resulting in the outward migration and spread of such societies even when population size is relatively small. In variable environments, stratified societies spread more and are also better able to survive resource shortages by sequestering mortality in the lower classes. The predictions of our simulation are provided modest support by a range of existing empirical studies. In short, the fact that stratified societies today vastly outnumber egalitarian societies may not be due to the transformation of egalitarian norms and structures, but may instead reflect the more rapid migration of stratified societies and consequent conquest or displacement of egalitarian societies over time

Ebf1 or Pax5 haploinsufficiency synergizes with STAT5 activation to initiate acute lymphoblastic leukemia

STAT5 is abnormally activated in patients with acute lymphoblastic leukemia, and increased STAT5 activation synergizes with PAX5 and EBF1 to induce disease

Making sense of diabetes medication decisions: a mixed methods cluster randomized trial using a conversation aid intervention.

PURPOSE: To determine the effectiveness of a shared decision-making (SDM) tool versus guideline-informed usual care in translating evidence into primary care, and to explore how use of the tool changed patient perspectives about diabetes medication decision making. METHODS: In this mixed methods multicenter cluster randomized trial, we included patients with type 2 diabetes mellitus and their primary care clinicians. We compared usual care with or without a within-encounter SDM conversation aid. We assessed participant-reported decisions made and quality of SDM (knowledge, satisfaction, and decisional conflict), clinical outcomes, adherence, and observer-based patient involvement in decision-making (OPTION12-scale). We used semi-structured interviews with patients to understand their perspectives. RESULTS: We enrolled 350 patients and 99 clinicians from 20 practices and interviewed 26 patients. Use of the conversation aid increased post-encounter patient knowledge (correct answers, 52% vs. 45%, p = 0.02) and clinician involvement of patients (Mean between-arm difference in OPTION12, 7.3 (95% CI 3, 12); p = 0.003). There were no between-arm differences in treatment choice, patient or clinician satisfaction, encounter length, medication adherence, or glycemic control. Qualitative analyses highlighted differences in how clinicians involved patients in decision making, with intervention patients noting how clinicians guided them through conversations using factors important to them. CONCLUSIONS: Using an SDM conversation aid improved patient knowledge and involvement in SDM without impacting treatment choice, encounter length, medication adherence or improved diabetes control in patients with type 2 diabetes. Future interventions may need to focus specifically on patients with signs of poor treatment fit. CLINICAL TRIAL REGISTRATION: ClinicalTrial.gov: NCT01502891
