Building Extension\u27s Capacity Through Knowledge of Global Aging Issues

A willingness to explore the global stage can improve and embellish Extension program development, implementation, and evaluation methods. Understanding various models of aging from around the world builds capacity and invites the cultivation of innovative responses in local communities. China is instructive to those interested in expanding their perspectives of older adult programming due to its large population, aging society, culture, and political reforms. Insight into Chinese efforts and the possible applicability of that response to Extension programming is shared through observations from the Seminar in Aging conducted by the American Society on Aging in Beijing in May 2007

Raising awareness of assistive technology in older adults through a community-based, Cooperative Extension program

The Fashion an Easier Lifestyle with Assistive Technology (FELAT) curriculum was developed as a needs-based, community educational program provided through a state Cooperative Extension Service. The overall goal for participants was to raise awareness of assistive technology. Program evaluation included a post-assessment and subsequent interview to determine short-term knowledge gain and longer-term behavior change. The sample consisted of mainly older, married females. The FELAT program was effective at raising awareness and increasing knowledge of assistive technology, and for many participants, the program acted as a catalyst for planning to or taking action related to assistive technology

The Development, Implementation, and Evaluation of a Pilot Program Designed to Enhance Wellbeing through Self-Identified

We describe the development, implementation, and evaluation of an introductory and interdisciplinary program to increase participants’ knowledge and awareness of wellbeing and intention to implement self-identified lifestyle changes. “Wellness and Wellbeing: What About Me?” was a University Extension pilot program that was designed to introduce wellbeing as a multidimensional construct. The program was delivered by Extension professionals in 14 sites across Iowa. Program evaluation consisted of a post-program assessment at the end of the seven-week series. The majority of the 115 post-program survey respondents were female, ranging in age from 22-88 years. Almost all survey respondents (89%) reported learning something new, and 94% reported that they intended to make a change to their lives because they attended the program. In addition, themes derived from open-ended survey responses supported the results related to awareness and intention to change behavior. Results from this pilot implementation were used to inform modifications to future program content, length, and dissemination efforts through Extension

Establishing a Common Language: The Meaning of Research-Based and Evidence-Based Programming (in the Human Sciences)

This article describes the development, implementation, and exploratory evaluation of a professional development series that addressed educators\u27 knowledge and use of the terms research-based and evidence-based within Human Sciences Extension and Outreach at one university. Respondents to a follow-up survey were more likely to select correctly the commonly accepted standard for each term, and they reported asking more questions, talking with others, examining programs\u27 evidence bases, and placing more value on fidelity and evaluation following participation in the professional development series. Educator reactions to the series were generally positive, although researchers interested in designing like programs might consider engaging educators within the context of their preexisting knowledge levels

Creating Opportunities Through an Experiential, Community-Based Cooperative Extension Internship Program

Extension is positioned to develop and implement high-quality, high-impact internship experiences for college students in local communities. The creation of the Rising Star Internship program arose from interest in providing experiential work opportunities for Iowa State University students coupled with the organizational goals of promoting awareness of Cooperative Extension and increasing interest in employability within Extension. The program provides a paid county-level summer internship with several unique elements. Evidence collected from student participants suggests that it is a mutually beneficial endeavor for Extension, students, and communities. Extension systems may desire to replicate these efforts if they share similar ambitions

A Joint Search for Gravitational Wave Bursts with AURIGA and LIGO

The first simultaneous operation of the AURIGA detector and the LIGO observatory was an opportunity to explore real data, joint analysis methods between two very different types of gravitational wave detectors: resonant bars and interferometers. This paper describes a coincident gravitational wave burst search, where data from the LIGO interferometers are cross-correlated at the time of AURIGA candidate events to identify coherent transients. The analysis pipeline is tuned with two thresholds, on the signal-to-noise ratio of AURIGA candidate events and on the significance of the cross-correlation test in LIGO. The false alarm rate is estimated by introducing time shifts between data sets and the network detection efficiency is measured with simulated signals with power in the narrower AURIGA band. In the absence of a detection, we discuss how to set an upper limit on the rate of gravitational waves and to interpret it according to different source models. Due to the short amount of analyzed data and to the high rate of non-Gaussian transients in the detectors noise at the time, the relevance of this study is methodological: this was the first joint search for gravitational wave bursts among detectors with such different spectral sensitivity and the first opportunity for the resonant and interferometric communities to unify languages and techniques in the pursuit of their common goal.Comment: 18 pages, IOP, 12 EPS figure

All-sky search for periodic gravitational waves in LIGO S4 data

We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1000 Hz and with the frequency's time derivative in the range -1.0E-8 Hz/s to zero. Data from the fourth LIGO science run (S4) have been used in this search. Three different semi-coherent methods of transforming and summing strain power from Short Fourier Transforms (SFTs) of the calibrated data have been used. The first, known as "StackSlide", averages normalized power from each SFT. A "weighted Hough" scheme is also developed and used, and which also allows for a multi-interferometer search. The third method, known as "PowerFlux", is a variant of the StackSlide method in which the power is weighted before summing. In both the weighted Hough and PowerFlux methods, the weights are chosen according to the noise and detector antenna-pattern to maximize the signal-to-noise ratio. The respective advantages and disadvantages of these methods are discussed. Observing no evidence of periodic gravitational radiation, we report upper limits; we interpret these as limits on this radiation from isolated rotating neutron stars. The best population-based upper limit with 95% confidence on the gravitational-wave strain amplitude, found for simulated sources distributed isotropically across the sky and with isotropically distributed spin-axes, is 4.28E-24 (near 140 Hz). Strict upper limits are also obtained for small patches on the sky for best-case and worst-case inclinations of the spin axes.Comment: 39 pages, 41 figures An error was found in the computation of the C parameter defined in equation 44 which led to its overestimate by 2^(1/4). The correct values for the multi-interferometer, H1 and L1 analyses are 9.2, 9.7, and 9.3, respectively. Figure 32 has been updated accordingly. None of the upper limits presented in the paper were affecte

Search for gravitational waves from binary inspirals in S3 and S4 LIGO data

We report on a search for gravitational waves from the coalescence of compact binaries during the third and fourth LIGO science runs. The search focused on gravitational waves generated during the inspiral phase of the binary evolution. In our analysis, we considered three categories of compact binary systems, ordered by mass: (i) primordial black hole binaries with masses in the range 0.35 M(sun) < m1, m2 < 1.0 M(sun), (ii) binary neutron stars with masses in the range 1.0 M(sun) < m1, m2 < 3.0 M(sun), and (iii) binary black holes with masses in the range 3.0 M(sun)< m1, m2 < m_(max) with the additional constraint m1+ m2 < m_(max), where m_(max) was set to 40.0 M(sun) and 80.0 M(sun) in the third and fourth science runs, respectively. Although the detectors could probe to distances as far as tens of Mpc, no gravitational-wave signals were identified in the 1364 hours of data we analyzed. Assuming a binary population with a Gaussian distribution around 0.75-0.75 M(sun), 1.4-1.4 M(sun), and 5.0-5.0 M(sun), we derived 90%-confidence upper limit rates of 4.9 yr^(-1) L10^(-1) for primordial black hole binaries, 1.2 yr^(-1) L10^(-1) for binary neutron stars, and 0.5 yr^(-1) L10^(-1) for stellar mass binary black holes, where L10 is 10^(10) times the blue light luminosity of the Sun.Comment: 12 pages, 11 figure

Search for gravitational-wave bursts in LIGO data from the fourth science run

The fourth science run of the LIGO and GEO 600 gravitational-wave detectors, carried out in early 2005, collected data with significantly lower noise than previous science runs. We report on a search for short-duration gravitational-wave bursts with arbitrary waveform in the 64-1600 Hz frequency range appearing in all three LIGO interferometers. Signal consistency tests, data quality cuts, and auxiliary-channel vetoes are applied to reduce the rate of spurious triggers. No gravitational-wave signals are detected in 15.5 days of live observation time; we set a frequentist upper limit of 0.15 per day (at 90% confidence level) on the rate of bursts with large enough amplitudes to be detected reliably. The amplitude sensitivity of the search, characterized using Monte Carlo simulations, is several times better than that of previous searches. We also provide rough estimates of the distances at which representative supernova and binary black hole merger signals could be detected with 50% efficiency by this analysis.Comment: Corrected amplitude sensitivities (7% change on average); 30 pages, submitted to Classical and Quantum Gravit
