    Models and Simulations in Material Science: Two Cases Without Error Bars

    Full text link
    We discuss two research projects in material science in which the results cannot be stated with an estimation of the error: a spectro- scopic ellipsometry study aimed at determining the orientation of DNA molecules on diamond and a scanning tunneling microscopy study of platinum-induced nanowires on germanium. To investigate the reliability of the results, we apply ideas from the philosophy of models in science. Even if the studies had reported an error value, the trustworthiness of the result would not depend on that value alone.Comment: 20 pages, 2 figure

    Addressing the Elephant in the Room: Understanding the Daily Life of Undocumented Latino High School Youth

    The 1.5 generation are the undocumented students who were born abroad and were brought to the United States by their parents at an early age. Many of these children came here during the population boom in the 1990’s and are now teenagers or in their mid 20’s. As they are finishing high school, nearly all of them are confused about their post-secondary options because of their undocumented status. The IL Dream Act, passed in 2011, qualifies undocumented youth to pay in-state tuition when attending public universities in Illinois and provides trained counselors who are aware of the college options and post-secondary resources for undocumented youth. However, this research shows that counselors may still be confused and unaware of the resources for their undocumented students, and about the struggles of their daily lives. This study intends to discover what school staff in McLean County know about the everyday life of their undocumented students and what kinds of post-secondary resources (available through the IL Dream Act) are being recommended to this unique group of students

    Working with Undocumented High School Students: A Psychosocial Guide to Understanding the Daily Life of Undocumented Youth

    Get PDF
    This guide is intended for high school principals, teachers, and counselors to enhance their understanding of the range of psychosocial constraints that impact the daily lives and health of their undocumented students. The goal is to create safe zones and effective support net-works and encourage undocumented youth to pursue post-secondary education

    Abstract LEXICAL ACCESS IN CHILDREN WITH SPECIFIC LANGUAGE IMPAIRMENT AND AUDITORY PROCESSING DEFICITS By Laura Sylvia The purpose of this study was to investigate the time line of lexical access in 8-11 year-old children with Specific Language Impairment and with and without deficits in auditory processing. Typically developing children and children with SLI, ages 8-11 years, participated in a Picture-Word Interference (PWI) task and a Picture-Picture Interference (PPI) task. For both tasks, subjects named a familiar target picture while ignoring an auditory word in the PWI task and an interfering picture in the PPI task. The interfering stimuli were presented at four stimulus onset asynchronies (SOAs) relative to the onset of the target picture (-150 ms, 0 ms, +150 ms, +300 ms) and were either unrelated to the target picture or related semantically or phonologically. Reaction time for naming was measured and reaction time differences (Related-Unrelated) were obtained for both tasks. All children also underwent language, cognitive and auditory processing test batteries which included the SCAN 3: C screening test, individual IMAP tests (Moore et al., 2010) and derived measures of temporal and frequency resolution. Multi-level modeling was employed to investigate relationships between all scores and reaction time in the PWI and PPI tasks. Results demonstrated significant early effects (-150ms SOA) in the lexicalization process in the PWI task and later (+150ms SOA) in the lexicalization process in the PPI task. In the children with SLI, “bottom-up” derived measures of temporal resolution and frequency resolution, contributed to overall reaction time in the PWI task, which employed an auditory distractor, but the derived measures did not contribute to overall reaction time in the PPI task, which employed a picture distractor. For typically developing children, this distinction was not observed

    Causes and trends of the digital divide: a European perspective

    Full text link
    "Starting point of the author's research is the appearance of a new form of social inequality: the digital divide. He defines this abstract notion as the opening cleavage between the information poor and the information rich, forming an additional source of inequality within the already established social ordering. He deals with reasons for private computer and internet use. The general question is who uses internet for her or his private ends and how do we explain possible differences. Research on this topic sometimes is challenged by charges of studying a non-existent myth or 'luxury' problem. However, computer literacy seems to be significantly related to socioeconomic positions. Most of the studies deal with the numbers and counts of computers, hosts, internet connections, indicating a predominantly economistic view towards the problem. This approach, however, disregards all other social, cultural, or technological implications. His results indicate that human capital and social capital are more important than economic capital when looking at the pathways of innovation diffusion. All in all, money seems to be the least important measure to understand patterns of the unequal technology diffusion. He concludes that successful new technologies do not diffuse haphazardly but systematically into our society. The usual diffusion process is a vertical movement from the highest to the lowest status position along the socio-economic strata until most households directly or indirectly are included."
