Evangelical Christians in Canadian National Television News, 1994–2004: A Frame Analysis

Recent surveys have shown that most evangelical Christians in Canada believe that the news media treat them unfairly. This study empirically tested the validity of the evangelicals’ charge against the media by examining the frames used in the nightly, national news reports of Global, CBC and CTV television networks. An analysis of all reports featuring evangelicals showed that neutral and positive frames, together, were almost equal in strength and number to negative frames used; this resulted in an overall rating of “balanced” for the coverage. While overall the coverage was balanced, the frequency and exclusivity of certain negative frames elevated their saliency considerably. For example, the “evangelicals as intolerant” frame alone appeared in one quarter of all reports. Regarding topic of the news reports, evangelicals most often received coverage for involvement in politics followed closely by involvement in criminal or immoral actions. Implications of these results are discussed

Implementing an Evidence-Based Fall Prevention Plan to Address Unintentional Hospital Falls on a Medical/Surgical Unit

Background: Falling in the hospital setting is a leading cause of death and disability for patients. For many health care organizations, patient fall prevention strategies have become a priority focus to improve patient outcomes and associated costs. Project Design: The project was designed to implement a quality improvement project on an adult medical/surgical unit, providing educational activities to nursing staff, and applying a standardized fall prevention plan of care “toolkit” for fall prevention interventions. Results: Audits completed on 863 patient admits to a 36-bed Medical/Surgical unit during the three-month timeframe, showed the implementation of the project resulted in the creation of a personalized fall prevention plan for 96% of the patients admitted. Unintentional patient falls for the unit decreased from 5.26 falls per 1000 patient days the previous year to 1.78 patient falls per 1000 patient days during the three months the project was implemented. Patient knowledge audits showed 94% of patients were able to identify at least one of their fall risk factors and 93% were able to verbalize a fall prevention intervention. Recommendations: The results of the pilot study indicate the project should be implemented on other units to help decrease patient falls hospital wide. Ensuring hospital and clinical leadership are engaged in the project is crucial to the success of translating evidence-based care into clinical practice. A patient-care team partnership appears to be beneficial for prevention of falls and fall-related injuries. Conclusions: The implementation of a standardized fall prevention program decreased patient falls in the medical/surgical setting over a three-month period. On-going monitoring is needed to continue to evaluate the effectiveness of the program

Nuclear Equation of State from Observations of Short Gamma-Ray Burst Remnants

The favoured progenitor model for short $\gamma$-ray bursts (SGRBs) is the merger of two neutron stars that triggers an explosion with a burst of collimated $\gamma$-rays. Following the initial prompt emission, some SGRBs exhibit a plateau phase in their $X$-ray light curves that indicates additional energy injection from a central engine, believed to be a rapidly rotating, highly magnetised neutron star. The collapse of this `protomagnetar' to a black hole is likely to be responsible for a steep decay in $X$-ray flux observed at the end of the plateau. In this letter, we show that these observations can be used to effectively constrain the equation of state of dense matter. In particular, we show that the known distribution of masses in binary neutron star systems, together with fits to the $X$-ray light curves, provide constraints that exclude the softest and stiffest plausible equations of state. We further illustrate how a future gravitational wave observation with Advanced LIGO/Virgo can place tight constraints on the equation of state, by adding into the picture a measurement of the chirp mass of the SGRB progenitor.Comment: accepted for publication in Phys.

Processing Multispectral Scanner Data Using Correlation Clustering and Nonparametric Classification Techniques

A two-step classification algorithm for processing multispectral scanner data has been developed and tested. The algorithm is carried out by two separate programs called CLUSTX and GROUPX. The program CLUSTX is a single pass clustering algorithm that assigns each pixel, based on its spectral signature, to one of NCLUST clusters. The output of the program CLUSTX is a cluster tape in which a single integer is associated with each pixel, This integer is the cluster number to which the pixel has been assigned by the program

Acute and chronic effects of multivitamin/mineral supplementation on objective and subjective energy measures

Background: Vitamins and minerals play an essential role within many cellular processes including energy production and metabolism. Previously, supplementation with a multivitamin/mineral (MVM) for ≥28 days resulted in improvements to cognition and subjective state. We have also demonstrated shifts in metabolism during cognitively demanding tasks following MVM in females, both acutely and following 8-week supplementation. The current study aimed to assess these effects further in males and females using metabolically challenging exercise and cognitive tasks. Methods: The current randomised, placebo-controlled, parallel groups study investigated the effects of a MVM complex in 82 healthy young (18-35y) exercisers. Subjective ratings and substrate metabolism were assessed during 30 min each of increasingly effortful incremental exercise and demanding cognitive tasks. Assessments took place on acute study days following a single dose (Day 1) of MVM, containing 3 times recommended daily allowance of water-soluble vitamins plus CoQ10, and following 4-week supplementation (Day 28). Results: Energy expenditure (EE) was increased during cognitive tasks following MVM across Day 1 and Day 28, with greater effects in males. In males, MVM also increased carbohydrate oxidation and energy expenditure during exercise across Day 1 and Day 28. In females, mental tiredness was lower during exercise; increases in physical tiredness following 30 min of exercise were attenuated; and stress ratings following cognitive tasks were reduced following MVM. In males, MVM only lowered mental tiredness following 10 min of exercise. These effects were apparent irrespective of day, but effects on mental tiredness were greater on Day 28. Ferritin levels were also higher on Day 28 in those receiving MVM. Conclusion: These findings extend on existing knowledge, demonstrating increased carbohydrate oxidation and increased energy expenditure in males following MVM supplementation for the first time. Importantly, they show modulation of energy expenditure and subjective tiredness following a single dose, providing further evidence for acute effects of MVM. Differential effects in men and women suggest that sex may play an important role in the effects of MVM on energy metabolism and should be considered in future research.

Intelligent building systems: Security and facility professionals’ understanding of system threats,vulnerabilities and mitigation practice

Intelligent Buildings or Building Automation and Control Systems (BACS) are becoming common in buildings, driven by the commercial need for functionality, sharing of information, reduced costs and sustainable buildings. The facility manager often has BACS responsibility; however, their focus is generally not on BACS security. Nevertheless, if a BACS-manifested threat is realised, the impact to a building can be significant, through denial, loss or manipulation of the building and its services, resulting in loss of information or occupancy. Therefore, this study garnered a descriptive understanding of security and facility professionals’ knowledge of BACS, including vulnerabilities and mitigation practices. Results indicate that the majority of security and facility professionals hold a general awareness of BACS security issues, although they lacked a robust understanding to meet necessary protection. For instance, understanding of 23 BACS vulnerabilities were found to be equally critical with limited variance. Mitigation strategies were no better, with respondents indicating poor threat diagnosis. In contrast, cybersecurity and technical security professionals such as integrators or security engineering design professionals displayed a robust understanding of BACS vulnerabilities and resulting mitigation strategies. Findings support the need for greater awareness for both security management and facility professionals of BACS vulnerabilities and mitigation strategies

Study of Stopping Sites of B12 Nuclei Implanted in Hexagonal Single-Crystals

A series of experiments to study the stopping sites of 12B nuclei implanted in single crystals of Be and Mg will be discussed. Previous measurements of the quadrupole couplings of 12B in these metals indicated that two different stopping sites existed, one of which produced a negligible quadrupole coupling

Quadrupole Couplings of N12 and B12 Implanted in Metal Single-Crystals

Measurements have been made of the quadrupole couplings of 12N implanted in single crystals of Be and Mg and of 12B implanted in a single crystal of Zn. A comparison of the 12N couplings in Be and Mg suggests that (i) the final stopping sites of the implanted 12N ions are substitutional sites, i.e., the 12N ions occupy metal-ion lattice positions, and (ii) the 12N ions implanted in Be and Mg have the same charge state and quadrupole shielding factor. A procedure is outlined for deducing Q(12N). The 12B couplings in Zn imply the existence of two inequivalent stopping sites. The problems encountered in deducing Q(12B) from couplings in metal hexagonal crystals are discussed
