TL;DR: Multivariate analyses showed that the following factors were statistically significantly associated with an increased rate of falls: dizziness, frequent physical activity, and having days on which activities were limited because of a health problem.
Abstract: To determine the frequency of and risk factors for falls and injurious falls in the noninstitutionalized elderly, the authors conducted a follow-up study of 409 community-dwelling persons aged 65 years or more in west-central Montreal, Quebec, Canada, from May 1987 to October 1988. Following an initial at-home interview, each subject was telephoned every 4 weeks for 48 weeks for collection of data on falls experienced since the last contact. Each of the 12 follow-up interviews was completed by at least 90% of the subjects eligible for interview. Data were also collected in the follow-up interviews on time-varying exposures. Twenty-nine percent of the subjects fell during follow-up; 17.6% fell once, and 11.5% fell two or more times. The incidence rate for falls was 41.4 falls per 1,000 person-months. The majority of falls resulted in no injury or in minor injury only. Potential risk factors investigated included sociodemographic variables, physical activity, alcohol consumption, acute and chronic health problems, dizziness, mobility, and medications. Multivariate analyses showed that the following factors were statistically significantly associated with an increased rate of falls: dizziness (incidence rate ratio (IRR) = 2.0), frequent physical activity (IRR = 2.0), having days on which activities were limited because of a health problem (IRR = 1.8), having trouble walking 400 m (IRR = 1.6), and having trouble bending down (IRR = 1.4). Factors which were protective included diversity of physical activities (IRR = 0.6), daily alcohol consumption (IRR = 0.5), having days spent in bed because of a health problem (IRR = 0.5), and taking heart medication (IRR = 0.6). Risk factors for injurious falls were similar.

TL;DR: In this article, the authors provide guidance in the use and interpretation of cone calorimetry for those directly involved with such measurements, and discuss the fire scenario with respect to applied heat flux, length scale, temperature, ventilation, anaerobic pyrolysis and set-up represented by the cone.
Abstract: There is little consensus within the fire science community on interpretation of cone calorimeter data, but there is a significant need to screen new flammability modified materials using the cone calorimeter. This article is the result of several discussions aiming to provide guidance in the use and interpretation of cone calorimetry for those directly involved with such measurements. This guidance is essentially empirical, and is not intended to replace the comprehensive scientific studies that already exist. The guidance discusses the fire scenario with respect to applied heat flux, length scale, temperature, ventilation, anaerobic pyrolysis and set-up represented by the cone calorimeter. The fire properties measured in the cone calorimeter are discussed, including heat release rate and its peak, the mass loss and char yield, effective heat of combustion and combustion efficiency, time to ignition and CO and smoke production together with deduced quantities such as FIGRA and MARHE. Special comments are made on the use of the cone calorimeter relating to sample thickness, textiles, foams and intumescent materials, and the distance of the cone heater from the sample surface. Finally, the relationship between cone calorimetry data and other tests is discussed. Copyright © 2007 John Wiley & Sons, Ltd.

TL;DR: The findings suggest that the onset of dementia-related syndromes may be initiated by repetitive cerebral concussions in professionalFootball players, and an earlier onset of Alzheimer's disease in the retirees than in the general American male population.
Abstract: Objective Cerebral concussion is common in collision sports such as football, yet the chronic neurological effects of recurrent concussion are not well understood. The purpose of our study was to investigate the association between previous head injury and the likelihood of developing mild cognitive impairment (MCI) and Alzheimer's disease in a unique group of retired professional football players with previous head injury exposure. Methods A general health questionnaire was completed by 2552 retired professional football players with an average age of 53.8 (+/-13.4) years and an average professional football playing career of 6.6 (+/- 3.6) years. A second questionnaire focusing on memory and issues related to MCI was then completed by a subset of 758 retired professional football players (> or = 50 yr of age). Results on MCI were then cross-tabulated with results from the original health questionnaire for this subset of older retirees. Results Of the former players, 61% sustained at least one concussion during their professional football career, and 24% sustained three or more concussions. Statistical analysis of the data identified an association between recurrent concussion and clinically diagnosed MCI (chi = 7.82, df = 2, P = 0.02) and self-reported significant memory impairments (chi = 19.75, df = 2, P = 0.001). Retired players with three or more reported concussions had a fivefold prevalence of MCI diagnosis and a threefold prevalence of reported significant memory problems compared with retirees without a history of concussion. Although there was not an association between recurrent concussion and Alzheimer's disease, we observed an earlier onset of Alzheimer's disease in the retirees than in the general American male population. Conclusion Our findings suggest that the onset of dementia-related syndromes may be initiated by repetitive cerebral concussions in professional football players.

TL;DR: Proximal defenses, which entail suppressing death-related thoughts or pushing the problem of death into the distant future by denying one's vulnerability, are rational, threat-focused, and activated when thoughts of death are in current focal attention.
Abstract: Distinct defensive processes are activated by conscious and nonconscious but accessible thoughts of death. Proximal defenses, which entail suppressing death-related thoughts or pushing the problem of death into the distant future by denying one's vulnerability, are rational, threat-focused, and activated when thoughts of death are in current focal attention. Distal terror management defenses, which entail maintaining self-esteem and faith in one's cultural worldview, function to control the potential for anxiety that results from knowing that death is inevitable. These defenses are experiential, are not related to the problem of death in any semantic or logical way, and are increasingly activated as the accessibility of death-related thoughts increases, up to the point at which such thoughts enter consciousness and proximal threat-focused defenses are initiated. Experimental evidence for this analysis is presented.

TL;DR: In this article, a global database of 2,626 rainfall events that have resulted in shallow landslides and debris flows was compiled through a thorough literature search, and the rainfall and landslide information was used to update the dependency of the minimum level of rainfall duration and intensity likely to result in shallow landslide and debris flow established by Nel Caine in 1980.
Abstract: A global database of 2,626 rainfall events that have resulted in shallow landslides and debris flows was compiled through a thorough literature search. The rainfall and landslide information was used to update the dependency of the minimum level of rainfall duration and intensity likely to result in shallow landslides and debris flows established by Nel Caine in 1980. The rainfall intensity–duration (ID) values were plotted in logarithmic coordinates, and it was established that with increased rainfall duration, the minimum average intensity likely to trigger shallow slope failures decreases linearly, in the range of durations from 10 min to 35 days. The minimum ID for the possible initiation of shallow landslides and debris flows was determined. The threshold curve was obtained from the rainfall data using an objective statistical technique. To cope with differences in the intensity and duration of rainfall likely to result in shallow slope failures in different climatic regions, the rainfall information was normalized to the mean annual precipitation and the rainy-day normal. Climate information was obtained from the global climate dataset compiled by the Climate Research Unit of the East Anglia University. The obtained global ID thresholds are significantly lower than the threshold proposed by Caine (Geogr Ann A 62:23–27, 1980), and lower than other global thresholds proposed in the literature. The new global ID thresholds can be used in a worldwide operational landslide warning system based on global precipitation measurements where local and regional thresholds are not available..
