The 'miss rate' for the analysis of gene expression data.
Multiple testing issues are important in gene expression studies, where typically thousands of genes are compared over two or more experimental conditions. The false discovery rate has become a popular measure in this setting. Here we discuss a complementary measure, the 'miss rate', and show how to estimate it in practice.

Inference for magnitudes and delays of responses in the FIAC data using BRAINSTAT/FMRISTAT.
We used straightforward linear mixed effects models as described in Worsley et al. together with recent advances in smoothing to control the degrees of freedom, and random field theory based on discrete local maxima. This has been implemented in BRAINSTAT, a Python version of FMRISTAT. Our main novelty is voxel-wise inference for both magnitude and delay (latency) of the hemodynamic response. Our analysis appears to be more sensitive than that of Dehaene-Lambertz et al. Our main findings are greater magnitude (1.08% +/- 0.17%) and delay (0.153 +/- 0.035 s) for different sentences compared to same sentences, together with a smaller but still significantly greater magnitude for different speaker compared to same speaker (0.47% +/- 0.08%).

Synthesis and integration of avian sarcoma virus DNA.
In this paper, we have presented data regarding the integration of viral DNA and the persistence of unintegrated viral DNA. We know that integration occurs with specificity with respect to the viral genome, and yet it remains to be established which, if any, of the unintegrated DS DNA species-either the linear or the covalently closed circular forms-is the immediate precursor to the DNA that does become integrated. The results of the present studies indicate that the viral DNA species that are able to persist in an unintegrated state may be transcribed to yield new virions. Furthermore, these species may not be intermediates as far as the integration pathway, but may instead be terminal products of a synthesis reaction that has proceeded beyond the point where integration normally occurs. Varmus et al. (1977) have shown that integration occurs only into newly replicated cellular DNA. Therefore, we would speculate that integration may occur by an interaction between a replication fork of the host cell DNA and an earlier, non-double-strand form of viral DNA.

SmartShape™ technology. Modifying the shape of the beef cuberoll and the consumer response to shaped scotch fillet steaks.
SmartShape™ is a novel meat processing technology that uses air pressure to compress and elongate whole cold-boned primals and packages them to retain form. A two stage study was conducted. The first stage established the ability of the SmartShape™ treated beef cube roll (m. longissimus lumborum) to retain shape in a commercial setting. Twelve hours chilling time following treatment was found to be adequate for steaks to retain their shape for up to 24h after slicing. Steak shape and size did not change substantially until after cooking, when the steaks looked less formed. In the second stage a survey was conducted of 421 consumers to clarify the response to the shaping of a subset of raw and cooked scotch fillet steaks. There was no difference in preference for shaped or control steaks. A secondary survey found that informed consumers were more amenable to the SmartShape™ scotch fillet steaks presented here, but would not pay a premium for them.

The influence of protection, palliation and costs on mobility optimization of residents in nursing homes: a thematic analysis of discourse.
BACKGROUND
With the aging of the population, increasing numbers of older people live in nursing homes. Discourse such as policies and standards highlight the need to optimize the mobility independence of residents. This is expected to occur in a way that is safe for residents and staff whilst meeting the residents' needs. The influence of discourse on health care delivery can be poorly understood, being at times hidden or taken for granted. The aim of this study was to uncover discourse relevant to resident mobility optimization to enable the origins and reasoning behind existing and intersecting policy and practice to be critically appraised.


DESIGN
Narrative literature review and thematic analysis with a focus on discourse were employed for this study.


DATA SOURCES
Databases (CINAHL and Ovid Medline) and websites of relevant professional and governmental bodies were accessed.


METHOD
A literature search centered on retrieval of texts focused on discourses that influenced goals to optimize resident mobility. Database searches for texts covered the period from 1994 to 2011. Iterative thematic analysis focussed on the texts' socio-cultural context and influence.


FINDINGS
Four discourses emerged that potentially influence goals to optimize resident mobility: safe manual handling; falls prevention; palliative care; and costs and funding constraints to individualized care. These discourses may influence mobility care in the direction of more routinized, passive and dependency support approaches. A common overarching theme was that of collaboration and communication.


CONCLUSION
Discourses such as safe manual handling, falls prevention, palliative care and cost constraints to individualized care can negatively impact on the goal to optimize the mobility of residents in nursing homes. Inter-professional approaches where staff work collaboratively and communicate well may counter such influences and ensure individualized care that focuses more effectively on resident mobility.

Results of a National Survey on Over-The-Counter Medicines, Part 1: Pharmacist Opinion on Current Scheduling Status
Background: OTC medicines make up an important part of the community pharmacy world. As with most aspects of practice, however, hurdles exist that prevent an optimal level of care. Objective: To gauge pharmacist agreement on the scheduling status of various OTC medicines. Methods: Pharmacists across Canada were surveyed by mail. Results: Of the 5037 surveys mailed, 2403 were returned, with 2305 being usable for analysis (response rate of 49.4%). Across 25 agents, pharmacists tended to support existing control for pharmacies (such as Nix crème rinse and minoxidil topical solution) and returning control to pharmacies for unscheduled agents (such as ranitidine 75 mg tablets and nicotine patches). Conclusions: Pharmacists generally favour tighter control of OTC agents, especially those that are unscheduled. This hopefully reflects pharmacist desire to ensure their proper selection and use.
