Collective action framing genetic engineering resistance in New Zealand
The genetic engineering resistance movement in New Zealand constructed strategic and meaningful interpretations of why the genetic engineering technique is problematic and what can be done about it. There are four central interpretations – explored here as collective action frames – that were used by key movement activists in their mobilisation activities. These four frames describe genetic engineering as ‘involving a wide range of issues’, ‘risky’, ‘unnatural’ and as ‘all about the ownership of life’. The characteristics of these frames are explained in this paper, along with an analysis of why it is that activists were able to achieve widespread resonance through their deployment of them. The successful framing and articulation of movement grievances is a critical movement activity for engagement of civil society in issues of great importance
Bolivia Or Bust: Cila Memories
The first tentative talks about the possibility of a teaching mission to Bolivia began in June of 1998 at the annual conference of the Association of Christian Librarians. We had a semi-formal meeting to discuss the possibility at the 1999 annual conference-nearly a year before it would actually happen-at a meeting of the Commission for International Library Assistance (CILA), a ministry of the Association. The mission of CILA is to provide support for libraries in developing countries where there is a lack of formal training or financial resources. It does so by serving as an umbrella organization to coordinate requests and match them up with volunteers willing to spend some time abroad
Red and photographic infrared linear combinations for monitoring vegetation
In situ collected spectrometer data were used to evaluate and quantify the relationships between various linear combinations of red and photographic infrared radiances and experimental plot biomass, leaf water content, and chlorophyll content. The radiance variables evaluated included the red and photographic infrared (IR) radiance and the linear combinations of the IR/red ratio, the square root of th IR/red difference, the vegetation index, and the transformed vegetation index. In addition, the corresponding green and red linear combinations were evaluated for comparative purposes. Three data sets were used from June, September, and October sampling periods. Regression analysis showed the increase utility of the IR and red linear combinations vis-a-vis the same green and red linear combinations. The red and IR linear combinations had 7% and 14% greater regression significance than the green and red linear combinations for the June and September sampling periods, respectively. The VI, TVI, and square root of the IR/red ration were the most significant followed closely by the IR/red ratio. Less than 6% difference separated the highest and lowest of these four IR and red linear combinations. The use of these linear combinations was shown to be sensitive primarily to the green leaf area or green leaf biomass

Will Expanding Health Care Coverage for People with Disabilities Increase their Employment and Earnings? Evidence from an Analysis of the SSI Work Incentive Program
Reports findings from study that examines the effect that increases in the income threshold under the Supplemental Security Income (SSI) work incentive program have on the employment, earnings, and program participation patterns of SSI recipients. Under Section 1619 of the Social Security Act, SSI recipients may maintain Medicaid eligibility, even if their income is above the level that makes them ineligible for SSI payments. If earnings increase beyond the threshold, however, the person loses their SSI and Medicaid eligibility. Findings indicate that many SSI recipients restrain their earnings to stay below the threshold, supporting the hypothesis that lack of access to health insurance is an important work disincentive for people with disabilities
Mobile sampler for use in acquiring samples of terrestrial atmospheric gases
Samples of terrestrial atmospheric gasses from a free body of such gasses using a device characterized by a plurality of tubular bodies adapted to be mounted in side by side relation on a motorized highway vehicle in mutual parallelism with the axis of the normal path of travel for the vehicles. Each of the bodies is of a cylindrical configuration and has an axial opening at each of its opposite ends through which a linear flow path is defined. A pair of pivotally supported, spring-biased sealing caps is mounted adjacent to the ends of the body and continuously urged into a hermetic sealing relationship. A restraint for securing the caps against spring-urged pivotal displacement, includes a separable, normally tensioned line interconnecting the caps and an operable release mechanism for simultaneously releasing the caps for spring-urged displacement. A hot wire cutter is included for separating the line, whereby samples of air are trapped in the body as the caps are spring-driven to assume an hermetically sealed relation with the openings defined in each of the opposite ends of the body
Temperature-based metallicity measurements at z=0.8: direct calibration of strong-line diagnostics at intermediate redshift
We present the first direct calibration of strong-line metallicity
diagnostics at significant cosmological distances using a sample at z=0.8 drawn
from the DEEP2 Galaxy Redshift Survey. Oxygen and neon abundances are derived
from measurements of electron temperature and density. We directly compare
various commonly used relations between gas-phase metallicity and strong line
ratios of O, Ne, and H at z=0.8 and z=0. There is no evolution with redshift at
high precision (, ). O, Ne, and H line ratios follow the same
locus at z=0.8 as at z=0 with 0.02 dex evolution and low scatter
(0.04 dex). This suggests little or no evolution in physical
conditions of HII regions at fixed oxygen abundance, in contrast to models
which invoke more extreme properties at high redshifts. We speculate that
offsets observed in the [N II]/H versus [O III]/H diagram at
high redshift are therefore due to [NII] emission, likely as a result of
relatively high N/O abundance. If this is indeed the case, then nitrogen-based
metallicity diagnostics suffer from systematic errors at high redshift. Our
findings indicate that locally calibrated abundance diagnostics based on
alpha-capture elements can be reliably applied at z1 and possibly at
much higher redshifts. This constitutes the first firm basis for the widespread
use of empirical calibrations in high redshift metallicity studies.Comment: 14 pages, 10 figures, accepted to Ap
Pseudomonas aeruginosa can be detected in a polymicrobial competition model using impedance spectroscopy with a novel biosensor
Electrochemical Impedance Spectroscopy (EIS) is a powerful technique that can be used to elicit information about an electrode interface. In this article, we highlight six principal processes by which the presence of microorganisms can affect impedance and show how one of these - the production of electroactive metabolites - changes the impedance signature of culture media containing Pseudomonas aeruginosa. EIS, was used in conjunction with a low cost screen printed carbon sensor to detect the presence of P. aeruginosa when grown in isolation or as part of a polymicrobial infection with Staphylococcus aureus. By comparing the electrode to a starting measurement, we were able to identify an impedance signature characteristic of P. aeruginosa. Furthermore, we are able to show that one of the changes in the impedance signature is due to pyocyanin and associated phenazine compounds. The findings of this study indicate that it might be possible to develop a low cost sensor for the detection of P. aeruginosa in important point of care diagnostic applications. In particular, we suggest that a development of the device described here could be used in a polymicrobial clinical sample such as sputum from a CF patient to detect P. aeruginosa
An investigation of the relationship between rumination styles, hope, and suicide ideation through the lens of the integrated motivational-volitional model of suicidal behavior
To investigate the roles specific ruminative styles (brooding and reflection) and hope play in the Integrated Motivational-Volitional (IMV) model of suicidal behavior. Participants were students from a large U.S. state university who were selectively sampled for the experience of recent suicide ideation. Results of a bootstrapped moderated mediation model indicated that defeat had a direct effect on suicide ideation but not an indirect effect on suicide ideation through entrapment. Brooding, but not reflection, strengthened the relationship between defeat and entrapment. Hope weakened the relationship between entrapment and suicide ideation. Implications for the assessment and treatment of suicide risk and future research directions are discussed
