The effects of post-encoding stress on recognition memory: examining the impact of skydiving in young men and women

Prior studies have indicated that post-encoding stress can protect memories from the effects of forgetting, and this has been taken as evidence that stress facilitates memory consolidation. However, it is not known whether stress acts by directly influencing the strength of the underlying memories or whether it influences the generation process that plays a critical role in tests such as free recall. To address this issue, we examined the effects of stress produced by skydiving on recognition memory for negative and neutral pictures. Relative to a non-stress control condition, post-encoding stress in males was found to increase recognition memory for neutral pictures. However, stress was not found to improve recognition for emotional pictures, nor was it found to influence recognition memory in female participants. Additional analysis of recognition performance suggested that stress increased familiarity-based recognition rather than recollection. This study indicates that stress can improve familiarity-based recognition, thus showing that stress directly increases the strength of the underlying memories.     

Bicycle fatalities: Trends in crashes with and without motor vehicles in The Netherlands

Boufous and Olivier (2015) recently found an increasing trend of police-reported cyclist deaths in single-vehicle crashes while a decreasing trend was found for fatal bicycle-motor vehicle crashes. This study sets out to conduct the same trend analyses for the Netherlands using causes of death statistics. The results show that for 1996–2014, the number of cyclist deaths in motor vehicle collisions per km cycled (i.e. the risk) has declined by 3.8% per annum (95% CI: −4.6%, −3.0%) while the risk of cyclist deaths in crashes without motor vehicles increased by 7.0% per annum (95% CI: 5.5%, 8.7%). The large majority of cyclist deaths at the beginning of the study period were due to bicycle-motor vehicle crashes. By 2014, however, the share with motor vehicles was only slightly higher than the share without motor vehicles. We also conducted trend analyses controlling for age by stratifying into nine age groups. After controlling for age, the average annual decrease of cyclist deaths in crashes with motor vehicles was 5.4% (95% CI: −6.0% to − 4.7%). The average annual increase of deaths in crashes without motor vehicles was 4.4% (95% CI: 3.1–5.7%). These trends are more favourable than those without controlling for age which can be explained by more cycling among the elderly who have an elevated risk. We conclude that, similar to Australia, cyclist deaths following motor vehicle crashes in the Netherlands have decreased while deaths without motor vehicles have increased.     

Consequences for road traffic fatalities of the reduction in flying following September 11, 2001

Gigerenzer [Gigerenzer, G. (2004). Dread risk, September 11, and fatal traffic accidents. Psychological Science, 15, 286–287] argued that the increased fear of flying in the U.S. after September 11 resulted in a partial shift from flying to driving on rural interstate highways, with a consequent increase of 353 road traffic fatalities for October through December 2001. We reevaluated the consequences of September 11 by utilizing the trends in road traffic fatalities from 2000 to 2001 for January through August. We also examined which road types and traffic participants contributed most to the increased road fatalities. We conclude that (1) the partial modal shift after September 11 resulted in 1018 additional road fatalities for the three months in question, which is substantially more than estimated by Gigerenzer, (2) the major part of the increased toll occurred on local roads, arguing against a simple modal shift from flying to driving to the same destinations, (3) driver fatalities did not increase more than in proportion to passenger fatalities, and (4) pedestrians and bicyclists bore a disproportionate share of the increased fatalities.     

The Rise of the Conscious Feminine

SUMMARY

The rise of the conscious feminine in the world is welcome and overdue. However, the change in the balance of power between men and women in relationship is presenting the need to develop a better understanding of the archetypal characteristics of the masculine and feminine as well as the differences between men and women. This article explores some of the developmental differences, the maintenance of mutuality and learning connecting skills.     

The Rise and Fall of the YCW in England

In this paper we will report some of the findings of a study of the rise and fall of the Young Christian Worker movement in England and Wales. From its origins in the industrial north in the 1930s, the movement reached its peak in the early 1950s. Since then it has declined and yet many of the current generation of Catholic activists were strongly influenced by its ideology, ecclesiology, and inductive approach to finding Christian responses to social issues. We explore from a social movement perspective what social factors contributed to its early growth. The context for its decline in recent decades are the major post-war social and post-Vatican religious changes which have transformed English Catholicism. We argue that the two stages of the decline correspond closely to the passage through adolescence and the young adult years of two successive generations in the post-war years, the 'baby boomers' and the 'baby busters'.

The Rise and Fall of Syphilis in Renaissance Europe

The rapid changes that syphilis underwent after the first major outbreak that occurred in Naples in the mid-1490s are believed to constitute the first well-documented example of a human disease. The new plague was of exceptional virulence, highly contagious and causing severe ulceration at the site of infection. According to medical and other historical sources, the ‘genius epidemics’ changed some years after this onset, and a slower-progressing form of syphilis seems to have replaced the initial severe form, as do many virulent epidemic infectious diseases that appear in devastating forms in a previously uninfected population. But what exactly were the features of the disease at the moment of its appearance in Europe at the end of the fifteenth century? How many years did it take for the early, virulent form to be replaced and become endemic? What was the pace of these changes through the decades following the onset of the epidemic? In this essay, I review these issues through an analysis of a large number of chronologically-ordered primary historical sources.

An analysis of U.S. parachuting fatalities: 2000-2004

Between 2000 and 2004, 125 recreational parachuting fatalities were reported in the USA. Each was categorized using a previously reported taxonomy. While patterns of skydiving fatality were largely unchanged since the last such analysis of fatalities from 1993-1999, some variations were noted. As in previous analyses, most of the recent skydiving fatalities were the direct result of human error. Some examples of commonplace human error fatalities were turning low to the ground resulting in a hard landing, accidentally colliding with other skydivers resulting in entangled parachutes, and failure to deploy the reserve parachute correctly in the event of malfunctioning main parachute.     

School shooting fatalities and school corporal punishment: A look at the states

Student deaths from school shootings were examined across all 50 states according to the state’s policy on the use of corporal punishment in schools after controlling for associated differences in poverty rates and the prevalence of conservative Christian religions. There were significantly more school shooting deaths found in states allowing school corporal punishment compared with those that do not. The odds of fatal involvement in a school shooting were greatest in states permitting school corporal punishment compared with those prohibiting it (odds ratio, 2.04) or restricting it to districts serving less than half the student population (odds ratio, 1.77). Moreover, the rate of school corporal punishment was moderately correlated with the rate of fatal school shootings both across all states and within the South, the region in which endorsement of school corporal punishment is most prevalent.Aggr.

The Rise of Citizen Science in Health and Biomedical Research

Citizen science models of public participation in scientific research represent a growing area of opportunity for health and biomedical research, as well as new impetus for more collaborative forms of engagement in large-scale research. However, this also surfaces a variety of ethical issues that both fall outside of and build upon the standard human subjects concerns in bioethics. This article provides background on citizen science, examples of current projects in the field, and discussion of established and emerging ethical issues for citizen science in health and biomedical research.
