KIC 4552982 was the first ZZ Ceti (hydrogen-atmosphere pulsating white dwarf) identified to lie in the Kepler field, resulting in the longest pseudo-continuous light curve ever obtained for this type of variable star. In addition to the pulsations, this light curve exhibits stochastic episodes of brightness enhancement unlike any previously studied white dwarf phenomenon. We briefly highlight the basic outburst and pulsation properties in these proceedings.

Background Research into the use of digital technology for weight loss maintenance (intentionally losing at least 10% of initial body weight and actively maintaining it) is limited. The aim of this article was to systematically review randomized controlled trials (RCTs) reporting on the use of digital technologies for communicating on weight loss maintenance to determine its' effectiveness, and identify gaps and areas for further research. Methods A systematic literature review was conducted by searching electronic databases to locate publications dated between 2006 and February 2018. Criteria were applied, and RCTs using digital technologies for weight loss maintenance were selected. Results Seven RCTs were selected from a total of 6541 hits after de-duplication and criteria applied. Three trials used text messaging, one used e-mail, one used a web-based system and two compared such a system with face-to-face contact. From the seven RCTs, one included children (n = 141) and reported no difference in BMI Standard Deviation between groups. From the seven trials, four reported that technology is effective for significantly aiding weight loss maintenance compared with control (no contact) or face-to face-contact in the short term (between 3 and 24 months). Conclusions It was concluded that digital technologies have the potential to be effective communication tools for significantly aiding weight loss maintenance, especially in the short term (from 3 to 24 months). Further research is required into the long-term effectiveness of contemporary technologies. [ABSTRACT FROM AUTHOR]

Background: Within the last decade there has been a growth in the call-centre industry in the UK, with a growing awareness of the voice as an important tool for successful communication. Occupational voice problems such as occupational dysphonia, in a business which relies on healthy, effective voice as the primary professional communication tool, may threaten working ability and occupational health and safety of workers. While previous studies of telephone call-agents have reported a range of voice symptoms and functional vocal health problems, there have been no studies investigating the use and impact of vocal performance in the communication industry within the UK. This study aims to address a significant gap in the evidence-base of occupational health and safety research. The objectives of the study are: 1. to investigate the work context and vocal communication demands for call-agents; 2. to evaluate call-agents' vocal health, awareness and performance; and 3. to identify key risks and training needs for employees and employers within call-centres. Methods and design: This is an occupational epidemiological study, which plans to recruit callcentres throughout the UK and Ireland. Data collection will consist of three components: 1. interviews with managers from each participating call-centre to assess their communication and training needs; 2. an online biopsychosocial questionnaire will be administered to investigate the work environment and vocal demands of call-agents; and 3. voice acoustic measurements of a random sample of participants using the Multi-dimensional Voice Program (MDVP). Qualitative content analysis from the interviews will identify underlying themes and issues. A multivariate analysis approach will be adopted using Structural Equation Modelling (SEM), to develop voice measurement models in determining the construct validity of potential factors contributing to occupational dysphonia. Quantitative data will be analysed using SPSS version 15. Ethical approval is granted for this study from the School of Communication, University of Ulster. Discussion: The results from this study will provide the missing element of voice-based evidence, by appraising the interactional dimensions of vocal health and communicative performance. This information will be used to inform training for call-agents and to contribute to health policies within the workplace, in order to enhance vocal health. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the content validity and nursing sensitivity of six community-level outcomes from the Nursing Outcomes Classification (NOC; Johnson, Maas, & Moorhead, 2000).Design and Methods: A survey research design was used. Questionnaires were mailed to 300 public health nursing experts; 102 nurses responded. Experts evaluated between 11 and 30 indicators for each of the six outcomes for: (a) importance of the indicators for measuring the outcome, and (b) influence of nursing on the indicators. Content validity and nursing sensitivity of the outcomes were estimated with a modified Fehring technique.Findings: All outcomes were deemed important; only Community Competence had an outcome content validity score <.80. The outcome sensitivity score for Community Health: Immunity was .80; other outcome scores ranged from .62-.70. Indicator ratios for all 102 indicators met the study criterion for importance, with 87% designated as critical and 13% as supplemental. Sensitivity ratios reflected judgments that 45% of the indicators were sensitive to nursing intervention.Conclusions: The study provided evidence of outcome content validity and nursing sensitivity of the study outcomes; further validation research is recommended, followed by testing of the study outcomes in clinical practice. Community-level nursing-sensitive outcomes will potentially enable study of the efficacy and effectiveness of public health interventions focused on improving health of populations and communities.

One hundred seventy one nurses were surveyed about their use of 26 indirect care interventions. They indicated that they would not delegate to others the majority of the interventions. Their estimations of the time to perform each intervention were, for the most part, the same, regardless of size of hospital, shift work, and illness level of the patient. The results demonstrate the importance of defining the nurse's indirect care, or role as manager of the care environment role. The indirect care interventions in this study are included in the second edition of the Nursing Interventions Classification (NIC). [ABSTRACT FROM AUTHOR]
