The Prisoners’ Counsel Act 1836: Doctrine, Advocacy and the Criminal Trial

In recent years greater numbers of thinkers have considered the Prisoners' Counsel Act 1836 but have viewed the Act through the lens of Whig history, as a further manifestation of the modernisation of criminal justice in the inevitable march towards adversarialism. This article addresses how the Act has been understood within broader literature concerning the nineteenth century felony trial. In particular, greater attention is paid to how counsel reacted to the Act, considering the nature of the contemporary Bar, the apparent silence from the Bar in reaction to the Act, what evidence might be drawn upon to gauge how members of the Bar might have reacted to changes within the trial and some possible explanation for such reactions. Lastly, some conclusions are drawn as to what these reactions reveal about pervading perceptions of the Bar during the mid-nineteenth century

Is There Visual Lateralisation of the Sun Compass in Homing Pigeons?

Functional lateralisation in the avian visual system can be easily studied by testing monocularly occluded birds. The sun compass is a critical source of navigational information in birds, but studies of visual asymmetry have focussed on cues in a laboratory rather than a natural setting. We investigate functional lateralisation of sun compass use in the visual system of homing pigeons trained to locate food in an outdoor octagonal arena, with a coloured beacon in each sector and a view of the sun. The arena was rotated to introduce a cue conflict, and the experimental groups, a binocular treatment and two monocular treatments, were tested for their directional choice. Wefoundnosignificantdifferenceintestorientationbetweenthetreatments,withallgroupsshowing evidence of both sun compass and beacon use, suggesting no complete functional lateralisation of sun compass use within the visual system. However, reduced directional consistency of binocular vs. monocular birds may reveal a conflict between the two hemispheres in a cue conflict condition.

A new sighting study for the fixed concentration procedure to allow for gender differences

The fixed concentration procedure (FCP) has been proposed as an alternative to the median lethal concentration (LC50) test (organisation for economic co-operation and development (OECD) test guideline [TG] 403) for the assessment of acute inhalation toxicity. The FCP tests animals of a single gender (usually females) at a number of fixed concentration levels in a sequential fashion. It begins with a sighting study that precedes the main FCP study and is used to determine the main study starting concentration. In this paper, we propose a modification to the sighting study and suggest that it should be conducted using both male and female animals, rather than just animals of a single gender. Statistical analysis demonstrates that, when females are more sensitive, the new procedure is likely to give the same classification as the original FCP, whereas, if males are more sensitive, the new procedure is much less likely to lead to incorrect classification into a less toxic category. If there is no difference in the LC50 for females and males, the new procedure is slightly more likely to classify into a more stringent class than the original FCP. Overall, these results show that the revised sighting study ensures gender differences in sensitivity do not significantly impact on the performance of the FCP, supporting its use as an alternative test method for assessing acute inhalation toxicity

A statistical evaluation of the effects of gender differences in assessment of acute inhalation toxicity

Acute inhalation toxicity of chemicals has conventionally been assessed by the median lethal concentration (LC50) test (organisation for economic co-operation and development (OECD) TG 403). Two new methods, the recently adopted acute toxic class method (ATC; OECD TG 436) and a proposed fixed concentration procedure (FCP), have recently been considered, but statistical evaluations of these methods did not investigate the influence of differential sensitivity between male and female rats on the outcomes. This paper presents an analysis of data from the assessment of acute inhalation toxicity for 56 substances. Statistically significant differences between the LC50 for males and females were found for 16 substances, with greater than 10-fold differences in the LC50 for two substances. The paper also reports a statistical evaluation of the three test methods in the presence of unanticipated gender differences. With TG 403, a gender difference leads to a slightly greater chance of under-classification. This is also the case for the ATC method, but more pronounced than for TG 403, with misclassification of nearly all substances from Globally Harmonised System (GHS) class 3 into class 4. As the FCP uses females only, if females are more sensitive, the classification is unchanged. If males are more sensitive, the procedure may lead to under-classification. Additional research on modification of the FCP is thus proposed

Sitting time and step counts in office workers

BACKGROUND: Technological advances mean that many adults are now employed in sedentary occupations. Given evidence linking prolonged sitting to chronic disease risk, understanding sitting and physical activity in and outside the workplace may usefully inform effective interventions. AIMS: To assess sitting time and physical activity during and outside working hours in fulltime office workers. METHODS: Participants wore a pedometer and recorded sitting times and step counts during and outside working hours for seven days. Participants were divided into tertiles based on the proportion of time spent sitting at work. Sitting times and step counts reported outside work were compared between groups, using one-way analysis of variance. RESULTS: There were 72 participants. Almost two thirds (65%) of time at work was spent sitting. The sample accumulated 3742±2493 steps at work and 5159±2474 steps outside work on workdays. Participants in the highest tertile for workplace sitting reported sitting for longer than those in the lowest tertile during transport (64±59 vs 21±16 mins), after-work (154±30 vs 126±51mins) and at weekends (382±133 vs 288±124mins, all p<0.05). Work duration and steps reported outside work did not differ between groups. CONCLUSIONS: Office workers who sit for a large proportion of their working day also report sitting for longer outside work. They do not compensate for their sedentary behaviour at work by being more active outside work. Occupational health interventions should focus on reducing workplace and leisure-time sitting in sedentary office workers

Repeated training of homing pigeons reveals age dependent idiosyncrasy and visual landmark use.

Recent research into the navigational strategies of homing pigeons (Columba livia) inthe familiar area has highlighted the phenomenon of route fidelity – birds formingidiosyncratic flight paths to which they are loyal over multiple releases from the samesite, and even returning to this path when released from a near-by unfamiliar location.Such results highlight the potential importance of visual landmark cues in the homingprocess. However, not all birds have been shown to produce idiosyncratic routes orshow this route-joining behaviour. Here we use birds with and without flight experienceto study the formation of idiosyncratic routes when released repeatedly from a singlelocation, followed by two off-route releases with differing topography to see how flightexperience and local landmark features can influence navigational strategy in thefamiliar area. We found that, over the course of 20 sequential releases, birds withgreater flight experience tended to form idiosyncratic routes whereas less experiencedbirds did not show this tendency. When released from near-by sites (from which thebirds had not previously been released), a range of navigational strategies were seen,including flying parallel to the learned route (suggestive of a learned compassdirection), a direct flight path towards home (again indicative of compass use), re-joining the learned route, and following the coastline. These latter strategies aresuggestive of landmark usage. Analysis using time lag embedding was also used toassess the off-route releases, and the short-term correlation dimension valuesproduced (ranging from 1.5-2.5) were also indicative of strategies using one or twofactors (landmarks, compass, or a combination of these two). Individual birds oftenshowed different strategies at different sites, suggesting that the use of differentnavigational cues is highly flexible and situationally dependent

Understanding the security and privacy concerns about the use of identifiable health data in the context of the COVID-19 pandemic : survey study of public attitudes toward COVID-19 and data-sharing

Background: The COVID-19 pandemic increased the availability and use of population and individual health data to optimize tracking and analysis of the spread of the virus. Many health care services have had to rapidly digitalize in order to maintain the continuity of care provision. Data collection and dissemination have provided critical support for defending against the spread of the virus since the beginning of the pandemic; however, little is known about public perceptions of and attitudes toward the use, privacy, and security of data. Objective: The goal of this study is to better understand people’s willingness to share data in the context of the COVID-19 pandemic. Methods: A web-based survey was conducted on individuals’ use of and attitudes toward health data for individuals aged 18 years and older, and in particular, with a reported diagnosis of a chronic health condition placing them at the highest risk of severe COVID-19. Results: In total, 4764 individuals responded to this web-based survey, of whom 4674 (98.1%) reported a medical diagnosis of at least 1 health condition (3 per person on average), with type 2 diabetes (n=2974, 62.7%), hypertension (n=2147, 45.2%), and type 1 diabetes (n=1299, 27.4%) being most prominent in our sample. In general, more people are comfortable with sharing anonymized data than personally identifiable data. People reported feeling comfortable sharing data that were able to benefit others; 66% (3121 respondents) would share personal identifiable data if its primary purpose was deemed beneficial for the health of others. Almost two-thirds (n=3026; 63.9%) would consent to sharing personal, sensitive health data with government or health authority organizations. Conversely, over a quarter of respondents (n=1297, 27.8%) stated that they did not trust any organization to protect their data, and 54% (n=2528) of them reported concerns about the implications of sharing personal information. Almost two-thirds (n=3054, 65%) of respondents were concerned about the provisions of appropriate legislation that seeks to prevent data misuse and hold organizations accountable in the case of data misuse. Conclusions: Although our survey focused mainly on the views of those living with chronic health conditions, the results indicate that data sensitivity is highly contextual. More people are more comfortable with sharing anonymized data rather than personally identifiable data. Willingness to share data also depended on the receiving body, highlighting trust as a key theme, in particular who may have access to shared personal health data and how they may be used in the future. The nascency of legal guidance in this area suggests a need for humanitarian guidelines for data responsibility during disaster relief operations such as pandemics and for involving the public in their development

Cytomegalovirus viral load within blood increases markedly in healthy people over the age of 70 years

Background Cytomegalovirus (CMV) is a highly prevalent herpesvirus, which maintains lifelong latency and places a significant burden on host immunity. Infection is associated with increased rates of vascular disease and overall mortality in the elderly and there is an urgent need for improved understanding of the viral-host balance during ageing. CMV is extremely difficult to detect in healthy donors, however, using droplet digital PCR of DNA from peripheral blood monocytes, we obtained an absolute quantification of viral load in 44 healthy donors across a range of ages. Results Viral DNA was detected in 24 % (9/37) of donors below the age of 70 but was found in all individuals above this age. Furthermore, the mean CMV load was only 8.6 copies per 10,000 monocytes until approximately 70 years of age when it increased by almost 30 fold to 249 copies in older individuals (p < 0.0001). CMV was found within classical CD14+ monocytes and was not detectable within the CD14-CD16+ subset. The titre of CMV-specific IgG increased inexorably with age indicating that loss of humoral immunity is not a determinant of the increased viral load. In contrast, although cellular immunity to the structural late protein pp65 increased with age, the T cell response to the immediate early protein IE1 decreased in older donors. Conclusion These data reveal that effective control of CMV is impaired during healthy ageing, most probably due to loss of cellular control of early viral reactivation. This information will be of value in guiding efforts to reduce CMV-associated health complications in the elderly
