The Relationship among Caregiver Depressive Symptoms, Parenting Behavior, and Familycenter Care All

Background Parental depression has been associated with adverse child outcomes. However, the specific parenting behaviors that may result in such child outcomes and the effect of family-centered care (FCC) on positive parenting behavior of depressed parents has not previously been examined. Methods Data from the National Survey of Early Childhood Health was used (n = 2,068). Groups were stratified by the presence of parental depression and compared with regard to demographics and the mean number of specific positive parenting behaviors. Generalized linear models were developed based on testing whether individuals performed more or less than the median number of positive behaviors. Lastly, we tested whether depression independently predicted each outcome after adjustment for FCC, coping, social support, and ethnicity to evaluate if depression independently predicted each outcome after adjustment. Results No difference was found in demographic variables between parents who were depressed and not depressed. Parents who were not depressed performed significantly more routines (p = .036); reported coping better with parenting (p < .001); performed significantly less punitive behaviors (p = .022); and needed/had less social support (p = .002) compared with parents who were depressed. Individual items and scale scores were associated in the expected directions. FCC was independently associated with study variables but did not moderate the effect of depression. Conclusions These data identify specific parenting behaviors that differ between parents who report depressive symptoms compared with parents who do not have depressive symptoms. More targeted interventions coordinated through a medical home are needed for parents with depressive symptoms to reduce the child health disparities often associated with parental depression

Libraries of the Future

Libraries have been the source of innovation throughout human history. People today do not understand the importance of libraries and the resources they can provide to a community or society. This causes libraries to not receive the appropriate funding to support both their programs and new literary materials. The inspiration for libraries of the future is derived from the trends that will attract the citizens of tomorrow. Libraries will be more involved in the community and provide the public with accessible technology. Our ideas to improve libraries will gain the public’s interest and keep the fire of knowledge alive. Some of these ideas include creating a more relaxed area to draw in a larger audience, bringing in new and developing technologies that the public can access, and providing new educational opportunities that widen the purpose of libraries

Perspectives on Publication Among Highly Productive Women Adapted Physical Activity Scholars [Abstract]

The purpose was to examine perspectives on publication of highly productive women adapted physical activity scholars. In-depth interviews were conducted with 13 women from three countries, and data were analyzed utilizing constant comparison methodology. Profiles of two groups, significantly different on publication productivity, emerged and were named highest high producers (HHP) and other high producers (OHP). Similarities between the two groups included affective domain qualities, facilitating factors, and overcoming barriers. Differences were mainly in degree of self-determination, prioritization of writing relative to significant others, collaboration, and collegiality. Based on thematic analysis of interview data, we posited the following: high publication productivity of women adapted physical activity professionals is associated with internal motivation to write, which is enhanced by positive interactions with other professionals, supportive home environments, and supportive work environments.</jats:p

Preliminary in-Situ X-Ray Absorption Fine Structure Examination of Pt/C and PtCo/C Cathode Catalysts in an Operational Polymer Electrolyte Fuel Cell

State-of-the-art polymer electrolyte fuel cells require a conditioning period to reach optimized cell performance. There is insuffi cient understanding about the behavior of catalysts during this period, especially with regard to the changing environment of the cathode electrocatalyst, which is typically Pt nanoparticles supported on high surface area Vulcan XC-72 carbon (Pt/C). The purpose of this research was to record preliminary observations of the changing environment during the conditioning phase using X-Ray Absorption Fine Structure (XAFS) spectroscopy. XAFS was recorded for a Pt/C cathode at the Pt L3-edge and a PtCo/C cathode at both the Pt L3-edge and Co K-edge. Using precision machined graphite cell-blocks, both transmission and fl uorescence data were recorded at Sector 12-BM-B of Argonne National Laboratory’s Advanced Photon Source. The fl uorescence and transmission edge steps allow for a working description of the changing electrocatalyst environment, especially water concentration, at the anode and cathode as functions of operating parameters. These features are discussed in the context of how future analysis may correlate with potential, current and changing apparent thickness of the membrane electrode assembly through loss of catalyst materials (anode, cathode, carbon support). Such direct knowledge of the effect of the conditioning protocol on the electrocatalyst may lead to better catalyst design. In turn, this may lead to minimizing, or even eliminating, the conditioning period

Analysis of Candida albicans Mutants Defective in the Cdk8 Module of Mediator Reveal Links between Metabolism and Biofilm Formation

Candida albicans biofilm formation is a key virulence trait that involves hyphal growth and adhesin expression. Pyocyanin (PYO), a phenazine secreted by Pseudomonas aeruginosa, inhibits both C. albicans biofilm formation and development of wrinkled colonies. Using a genetic screen, we identified two mutants, ssn3Δ/Δ and ssn8Δ/Δ, which continued to wrinkle in the presence of PYO. Ssn8 is a cyclin-like protein and Ssn3 is similar to cyclin-dependent kinases; both proteins are part of the heterotetrameric Cdk8 module that forms a complex with the transcriptional co-regulator, Mediator. Ssn3 kinase activity was also required for PYO sensitivity as a kinase dead mutant maintained a wrinkled colony morphology in the presence of PYO. Furthermore, similar phenotypes were observed in mutants lacking the other two components of the Cdk8 module-Srb8 and Srb9. Through metabolomics analyses and biochemical assays, we showed that a compromised Cdk8 module led to increases in glucose consumption, glycolysis-related transcripts, oxidative metabolism and ATP levels even in the presence of PYO. In the mutant, inhibition of respiration to levels comparable to the PYO-treated wild type inhibited wrinkled colony development. Several lines of evidence suggest that PYO does not act through Cdk8. Lastly, the ssn3 mutant was a hyperbiofilm former, and maintained higher biofilm formation in the presence of PYO than the wild type. Together these data provide novel insights into the role of the Cdk8 module of Mediator in regulation of C. albicans physiology and the links between respiratory activity and both wrinkled colony and biofilm development

Evaluation of a Diagnostic Reasoning Program (DxR): Exploring Student Perceptions and Addressing Faculty Concerns

Abstract: Clinical reasoning is essentially a problem-solving process, in which medical students must learn to gather and interpret data, generate hypotheses and make decisions. To develop skills in problem-solving it is argued that students need more tools, rather than more answers (Masys, 1989). DxR is a computerised case series, in which students use 'doctor tools' to investigate a patient problem. This report describes a pilot evaluation of DxR in fourth year medicine at the University of Sydney. It addresses faculty concerns regarding the program, explores student perceptions, and looks at the capacity of the program to stimulate and support the development of clinical reasoning skills. It finally discusses possibilities for using DxR to support learning in medicine. Reviewers: Stig Andersen (Virtual Centre for Health Informatics, Aalborg, DK), David Good (U.

The Spitzer c2d survey of Large, Nearby, Interstellar Clouds. V. Chamaeleon II Observed with IRAC

We present IRAC (3.6, 4.5, 5.8, and 8.0 micron) observations of the Chamaeleon II molecular cloud. The observed area covers about 1 square degree defined by $A_V >2$. Analysis of the data in the 2005 c2d catalogs reveals a small number of sources (40) with properties similar to those of young stellaror substellar objects (YSOs). The surface density of these YSO candidates is low, and contamination by background galaxies appears to be substantial, especially for sources classified as Class I or flat SED. We discuss this problem in some detail and conclude that very few of the candidate YSOs in early evolutionary stages are actually in the Cha II cloud. Using a refined set of criteria, we define a smaller, but more reliable, set of 24 YSO candidates.Comment: 19 pages, 10 figures, in press Ap

The Spitzer c2d Survey of Large, Nearby, Interstellar Clouds. VII. Ophiuchus Observed with MIPS

We present maps of 14.4 deg^2 of the Ophiuchus dark clouds observed by the Spitzer Space Telescope Multiband Imaging Photometer for Spitzer (MIPS). These high-quality maps depict both numerous point sources and extended dust emission within the star-forming and non–star-forming portions of these clouds. Using PSF-fitting photometry, we detect 5779 sources at 24 μm and 81 sources at 70 μm at the 10 σ level of significance. Three hundred twenty-three candidate young stellar objects (YSOs) were identified according to their positions on the MIPS/2MASS K versus color-magnitude diagrams, as compared to 24 μm detections in the SWIRE extragalactic survey. We find that more than half of the YSO candidates, and almost all those with protostellar Class I spectral energy distributions, are confined to the known cluster and aggregates

Research on information systems failures and successes: status update and future directions

Information systems success and failure are among the most prominent streams in IS research. Explanations of why some IS fulfill their expectations, whereas others fail, are complex and multi-factorial. Despite the efforts to understand the underlying factors, the IS failure rate remains stubbornly high. A Panel session was held at the IFIP Working Group 8.6 conference in Bangalore in 2013 which forms the subject of this Special Issue. Its aim was to reflect on the need for new perspectives and research directions, to provide insights and further guidance for managers on factors enabling IS success and avoiding IS failure. Several key issues emerged, such as the need to study problems from multiple perspectives, to move beyond narrow considerations of the IT artifact, and to venture into underexplored organizational contexts, such as the public sector. © 2014 Springer Science+Business Media New York
