    The purpose of this study was to identify characteristics specific to adults who are caregivers while taking classes from an institution of higher education. We recruited 5 university attending adults through a subject pool and through announcements in various classes through the university setting. Measures on depression, burden, daily activities, and general background were used to assess the experiences of the participants. Self-reports indicated high levels of selfefficacy with regard to the care process, minimal depression, low to moderate levels of burden, and high resiliency among those surveyed. These results indicate while registered as a full time student (12 credits or more) daily activities remain high, while overall levels for depression and reported burden remain relatively low. This group of providers suggests a desire to continue with current responsibilities of providing care to the family member. More intensive analysis is needed to explain the resilient nature of this group. Degree seeking may provide a buffer from the traditional burden and depression often experienced by other caregivers who are not attending college

    Techno-Invasion: Are Blackberries Blurring the Line Between Work and Home

    This paper investigates the psychological costs of mandating information and communication technology (ICT), specifically Blackberries, in the workplace. Based on the literature on workfamily conflict and technostress, we explore whether Blackberries have caused workers to feel techno-invaded, thus interfering with the boundary between work and family. Using survey data from 76 workers at an eastern organization, we use regression analysis to test whether technoinvasion mediates the relationship between work-family conflict and work exhaustion. Results of the survey confirm that negative attitudes are arising from Blackberry usage. However, supplemental qualitative data counteracts this negative finding, suggesting that positive adjustments can advance the benefits of Blackberry usage while minimizing the costs. We end with implications for research and practice

    Aligning simulation models: A case study and results

    Full text link
    This paper develops the concepts and methods of a process we will call “alignment of computational models” or “docking” for short. Alignment is needed to determine whether two models can produce the same results, which in turn is the basis for critical experiments and for tests of whether one model can subsume another. We illustrate our concepts and methods using as a target a model of cultural transmission built by Axelrod. For comparison we use the Sugarscape model developed by Epstein and Axtell.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44707/1/10588_2005_Article_BF01299065.pd

    A Promiscuous Prion: Efficient Induction of [URE3] Prion Formation by Heterologous Prion Domains

    No full text
    The [URE3] and [PSI+] prions are the infections amyloid forms of the Saccharomyces cerevisiae proteins Ure2p and Sup35p, respectively. Randomizing the order of the amino acids in the Ure2 and Sup35 prion domains while retaining amino acid composition does not block prion formation, indicating that amino acid composition, not primary sequence, is the predominant feature driving [URE3] and [PSI+] formation. Here we show that Ure2p promiscuously interacts with various compositionally similar proteins to influence [URE3] levels. Overexpression of scrambled Ure2p prion domains efficiently increases de novo formation of wild-type [URE3] in vivo. In vitro, amyloid aggregates of the scrambled prion domains efficiently seed wild-type Ure2p amyloid formation, suggesting that the wild-type and scrambled prion domains can directly interact to seed prion formation. To test whether interactions between Ure2p and naturally occurring yeast proteins could similarly affect [URE3] formation, we identified yeast proteins with domains that are compositionally similar to the Ure2p prion domain. Remarkably, all but one of these domains were also able to efficiently increase [URE3] formation. These results suggest that a wide variety of proteins could potentially affect [URE3] formation

    Space Weather Monitoring at the Rosse Solar-Terrestrial Observatory

    <p>Poster at 14th European Solar Physics Meeting in Trinity College Dublin (www.espm14.ie).</p> <p>The Rosse Solar-Terrestrial Observatory (RSTO) was established at Birr Castle in the midlands of Ireland to study solar activity and space weather effects on the Earth's ionosphere and geomagnetic field. A set of solar radio spectrometers based on CALLISTO receivers monitor the Sun at 10-400 MHz, while a magnetometer is used to measure the local geomagnetic field and associated K-index. In addition, the ionosphere is monitored using a sudden ionospheric disturbance instrument. All data are provided in near-realtime at www.rosseobservatory.ie.</p
