Positioning Library Data for the Semantic Web: Recent Developments in Resource Description
Recent developments in resource description standards and technologies have aimed at moving cataloging practice to the web environment and making library data available for exchange and reuse on the Semantic Web. As the library community looks outward and forward, library standards and technologies are converging with Web practices in three areas: content description, data models, and data exchange. This article captures the essence of the core standards and technologies that underlie the daily work of practitioners of library service, including Resource Description and Access (RDA), Functional Requirements for Bibliographic Records (FRBR), the Linked Data environment, Resource Description Framework (RDF), and the Bibliographic Framework Transition Initiative (BIBFRAME). The article will discuss their intersections with existing practice during this period of transition, as well as their potential impacts on the future cataloging practice
The Influence of Nurse Logs on Seedlings and Trees in Temperate Rainforests
Nurse logs provide safe sites from biotic and abiotic factors inhibiting seedling establishment and growth on the forest floor. Nurse logs therefore disrupt density dependent effects of fungal pathogens on seedlings
Preschool Teachers\u27 Views of Literacy Instruction
Students in Pennsylvania are falling behind in reading proficiency. Early literacy skills are the foundation for future reading success and students who have not learned to read proficiently by the end of 3rd grade have an increased chance of failing to achieve academic success. The purpose of this quantitative correlational study was to investigate the relationship between preschool teachers\u27 perceived self-efficacy for literacy instruction and preschool literacy assessment scores of students at local private preschool classrooms. The research question focused on the relationship between preschool teacher self-efficacy for literacy instruction and student literacy achievement. Bandura\u27s self-efficacy theory served as the theoretical foundation of the study. Preschool teachers\u27 (n = 31) perceived levels of self-efficacy for early literacy instruction was measured using the Komlodi Assessment for Self-efficacy (KASE) survey. A Pearson correlation analysis of the KASE survey data along with preschool student literacy assessment scores from the Teaching Strategies GOLD preschool assessment was completed to determine whether a relationship exists. The results, however, revealed no significant correlation between teacher self-efficacy and student literacy achievement. The findings suggested that the preschool teachers perceived themselves as effective in both literacy instruction and knowledge of literacy concepts, but less efficacious in their ability to diagnose and provide successful interventions to students struggling with literacy. Recommendations include offering professional development opportunities to strengthen the skills where preschool teachers feel less effective. A focus on professional development and support for teachers may promote social change as students achieve higher early literacy proficiency and become successful members of society
Freezing Out Early Dark Energy
A phenomenological model of dark energy that tracks the baryonic and cold
dark matter at early times but resembles a cosmological constant at late times
is explored. In the transition between these two regimes, the dark energy
density drops rapidly as if it were a relic species that freezes out, during
which time the equation of state peaks at +1. Such an adjustment in the dark
energy density, as it shifts from scaling to potential-domination, could be the
signature of a trigger mechanism that helps explain the late-time cosmic
acceleration. We show that the non-negligible dark energy density at early
times, and the subsequent peak in the equation of state at the transition,
leave an imprint on the cosmic microwave background anisotropy pattern and the
rate of growth of large scale structure. The model introduces two new
parameters, consisting of the present-day equation of state and the redshift of
the freeze-out transition. A Monte Carlo Markov Chain analysis of a
ten-dimensional parameter space is performed to compare the model with
pre-Planck cosmic microwave background, large scale structure and supernova
data and measurements of the Hubble constant. We find that the transition
described by this model could have taken place as late as a redshift z~400. We
explore the capability of future cosmic microwave background and weak lensing
experiments to put tighter constraints on this model. The viability of this
model may suggest new directions in dark-energy model building that address the
coincidence problem.Comment: 11 pages, 15 figure
Being Alone or Together:How Frontline Anthropomorphized Robots Affect Solo (vs. Joint) Service Consumption
Solo consumption has become an emerging trend in recent years. However, the service experiences of solo customers with the growing adoption of frontline humanlike robots remain unclear, particularly in direct comparison with joint customers. Building on the literature of anthropomorphism and information processing theory, this study examines whether and how frontline anthropomorphized robots (FAR) might improve the service experiences of solo customers relative to their joint counterparts. Data from four studies, including field and online experiments, reveal that solo customers are more likely than joint customers to perceive FAR as offering rapport but also as being eerie, leading to different service evaluations (both attitudinal and behavioral outcomes). Nevertheless, as parallel mechanisms, these levels of social rapport and eeriness are contingent on features of the FAR, the service delivery process, and customers’ consumption goals. The rapport (eeriness) mechanism is strengthened (weakened) when the robot is of in-group favoritism, the service process deprives customers of control, and customers have a hedonic consumption goal. With the boom in adopting frontline humanlike robots in hospitality services, this study offers managerially relevant implications for serving solo customers as an emerging segment along with the traditional segment of joint customers
Mitochondrial dysfunction and neurodegeneration in multiple sclerosis
Multiple sclerosis (MS) has traditionally been considered an autoimmune inflammatory disorder leading to demyelination and clinical debilitation as evidenced by our current standard anti-inflammatory and immunosuppressive treatment regimens. While these approaches do control the frequency of clinical relapses, they do not prevent the progressive functional decline that plagues many people with MS. Many avenues of research indicate that a neurodegenerative process may also play a significant role in MS from the early stages of disease, and one of the current hypotheses identifies mitochondrial dysfunction as a key contributing mechanism. We have hypothesized that pathological permeability transition pore (PTP) opening mediated by reactive oxygen species (ROS) and calcium dysregulation is central to mitochondrial dysfunction and neurodegeneration in MS. This focused review highlights recent evidence supporting this hypothesis, with particular emphasis on our in vitro and in vivo work with the mitochondria-targeted redox enzyme p66ShcA
