Extreme Weather and the Arctic Meltdown: How Are They Connected?

Does it seem as though the weather gods have gone crazy lately? It is not your imagination. The question on everyone\u27s minds is why? And is it related to climate change? In this presentation, Dr. Francis will explain new research that links increasing extreme weather events with the rapidly warming and melting Arctic during recent decades. Evidence suggests that Arctic warming is causing weather patterns to become more persistent, which can lead to extremes such as droughts, cold spells, heat waves, snowy winters, and some flooding events

Young people's attitudes to religious diversity : quantitative approaches from social psychology and empirical theology

This essay discusses the design of the quantitative component of the ‘Young People’s Attitudes to Religious Diversity’ project, conceived by Professor Robert Jackson within the Warwick Religions and Education Research Unit, and presents some preliminary findings from the data. The quantitative component followed and built on the qualitative component within a mixed method design. The argument is advanced in seven steps: introducing the major sources of theory on which the quantitative approach builds from the psychology of religion and from empirical theology; locating the empirical traditions of research among young people that have shaped the study; clarifying the notions and levels of measurement employed in the study anticipating the potential for various forms of data analysis; discussing some of the established measures incorporated in the survey; defining the ways in which the sample was structured to reflect the four nations of the UK, and London; illustrating the potential within largely descriptive cross-tabulation forms of analysis; and illustrating the potential within more sophisticated multivariate analytic models

TB191: Conservation and Management of Native Bees in Cranberry

Threats to agriculturally important pollinators have serious implications for human beings. A loss of bees translates to less successful crop pollination, thus reduced yield and poorer quality fruits. Native bees have the potential to serve as commercial pollinators. A diverse pollinator complex comprised of both honey bees and native bees should result in stable pollination levels and should be resistant to threats such as disease, fluctuating honey and crop prices, and honey bee transportation costs. Adding the goal of native bee conservation to land management increases the ecological integrity of an ecosystem by conserving a unique biological interaction that is the basis for most native wild plant reproduction. This report describes pollination in the cranberry agroecosystem and outlines steps to take to manage native bees in cranberry.https://digitalcommons.library.umaine.edu/aes_techbulletin/1017/thumbnail.jp

Radar Evaluation of Optical Cloud Constraints to Space Launch Operations

Weather constraints to launching space vehicles are designed to prevent loss of the vehicle or mission due to weather hazards (See, e.g., Ref 1). Constraints include Lightning Launch Commit Criteria (LLCC) designed to avoid natural and triggered lightning. The LLCC currently in use at most American launch sites including the Eastern Range and Kennedy Space Center require the Launch Weather Officer to determine the height of cloud bases and tops, the location of cloud edges, and cloud transparency. The preferred method of making these determinations is visual observation, but when that isn't possible due to darkness or obscured vision, it is permissible to use radar. This note examines the relationship between visual and radar observations in three ways: A theoretical consideration of the relationship between radar reflectivity and optical transparency. An observational study relating radar reflectivity to cloud edge determined from in-situ measurements of cloud particle concentrations that determine the visible cloud edge. An observational study relating standard radar products to anvil cloud transparency. It is shown that these three approaches yield results consistent with each other and with the radar threshold specified in Reference 2 for LLCC evaluation

Are different reading problems associated with different anxiety types?

There is a reliable association between poor reading and anxiety, but we do not completely understand the specifics of this relationship. The current study included a sample of children (N = 284; Mage = 9.30, SDage = 1.31) who completed a reading (word, nonword, and text reading accuracy, word, nonword, and text reading fluency, passage reading comprehension) and anxiety (social anxiety, generalized anxiety, separation anxiety, physical injury fears/phobias, panic, obsessive compulsive symptoms) assessment. Analyses included bivariate and partial correlations, principal components analysis, and hierarchical clustering. We found a very tentative suggestion in the data that there may be a specific yet weak association between reading accuracy and social anxiety. The clinical implications and directions for future research are discussed

Evidence for ADAR-induced hypermutation of the Drosophila sigma virus (Rhabdoviridae).

BACKGROUND: ADARs are RNA editing enzymes that target double stranded RNA and convert adenosine to inosine, which is read by translation machinery as if it were guanosine. Aside from their role in generating protein diversity in the central nervous system, ADARs have been implicated in the hypermutation of some RNA viruses, although why this hypermutation occurs is not well understood. RESULTS: Here we describe the hypermutation of adenosines to guanosines in the genome of the sigma virus--a negative sense RNA virus that infects Drosophila melanogaster. The clustering of these mutations and the context in which they occur indicates that they have been caused by ADARs. However, ADAR-editing of viral RNA is either rare or edited viral RNA are rapidly degraded, as we only detected evidence for editing in two of the 104 viral isolates we studied. CONCLUSION: This is the first evidence for ADARs targeting viruses outside of mammals, and it raises the possibility that ADARs could play a role in the antiviral defences of insects.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Norms in mixed sex and mixed race work groups

Abstract Norms determine regular patterns of behavior and influence members' identification with a group. They are also a proximate way to predict and understand behavior in diverse work groups but, surprisingly, have not been extensively examined in this context. After reviewing research on group norms and the psychology of prejudice, I suggest that reaping the benefits of the increased range of available task relevant resources in demographically diverse work groups may depend on the strength and content of the norms it adopts, but that diverse groups face distinct obstacles in developing strong norms that create satisfying interpersonal interaction and effective work performance. I consider the difficulties diverse work groups have in forming strong norms and then focus on how anti-bias norms, which are directed toward preventing behaviors associated with prejudice and discrimination and address members' security concerns, and openness norms, which promote people's ability to individuate those whom they might otherwise stereotype as well as address nurturance concerns, may increase a work group's ability to optimize social interaction and performance amidst

Creating inclusive environments in first-year engineering classes to support student retention and learning: paper

Includes bibliographical references.Paper given at the ASEE's 122nd Annual Conference & Exposition in Seattle, Washington, June 14-15, 2015.Paper ID #12401.A new NSF-funded experimental study seeks to incorporate innovative curriculum activities that cultivate inclusive engineering identities and demonstrate how the engineering profession benefits from diversity. We intend to expand first-year engineering student perceptions about who can be an engineer and what engineers do. This effort aims to create a cultural shift in engineering departments so students think beyond stereotypical perceptions of who belongs to the engineering profession (White men) toward more expansive notions about how the engineering profession needs diversity to thrive. Arguably, inclusive engineering departments will contribute to the retention and success of students who are underrepresented in engineering in terms of gender and race, but also in terms of backgrounds, talents, and interests. In this paper, we begin with an overview of scholarship regarding pedagogical practices that foster strong engineering identities and position diversity as essential for strong engineering practice. Next, we address the following research question: How do freshmen engineering students in traditional engineering courses identify with engineering and perceive diversity in engineering? To answer this question, we summarize findings from preliminary survey by tracking over time the engineering identities and perceptions about diversity in engineering of engineering freshmen during their first semester in two existing first-year courses. We conclude with theoretically-based and evidence-driven activities that will be incorporated in the same first-year engineering courses in subsequent years of this NSF grant.National Science Foundation, Grant # 1432601

Biochemical Kinetics Model of DSB Repair and GammaH2AX FOCI by Non-homologous End Joining

We developed a biochemical kinetics approach to describe the repair of double strand breaks (DSB) produced by low LET radiation by modeling molecular events associated with the mechanisms of non-homologous end-joining (NHEJ). A system of coupled non-linear ordinary differential equations describes the induction of DSB and activation pathways for major NHEJ components including Ku(sub 70/80), DNA-PK(sub cs), and the Ligase IV-XRCC4 hetero-dimer. The autophosphorylation of DNA-PK(sub cs and subsequent induction of gamma-H2AX foci observed after ionizing radiation exposure were modeled. A two-step model of DNA-PK(sub cs) regulation of repair was developed with the initial step allowing access of other NHEJ components to breaks, and a second step limiting access to Ligase IV-XRCC4. Our model assumes that the transition from the first to second-step depends on DSB complexity, with a much slower-rate for complex DSB. The model faithfully reproduced several experimental data sets, including DSB rejoining as measured by pulsed-field electrophoresis (PFGE), quantification of the induction of gamma-H2AX foci, and live cell imaging of the induction of Ku(sub 70/80). Predictions are made for the behaviors of NHEJ components at low doses and dose-rates, where a steady-state is found at dose-rates of 0.1 Gy/hr or lower
