Occupational Exposure To Snowmobile Emission At Yellowstone National Park, Wendy Campbell, Ryan Morris, Dale Stephenson, Terry Spear Feb 2005

Occupational Exposure To Snowmobile Emission At Yellowstone National Park, Wendy Campbell, Ryan Morris, Dale Stephenson, Terry Spear

Dale J. Stephenson

In recent years, regulations regarding snowmobile recreation in Yellowstone National Park have become more restrictive. New regulations limit the number of snowmobiles entering the park, restrict the engine type, and require that all riders must utilize a licensed guide. Given these regulations, it is hypothesized that occupational exposures to the combustion products from snowmobile exhaust have decreased. This research project performed occupational exposure monitoring of National Park Service Employees while working at the West Entrance to Yellowstone National Park during the 2004-2005 winter season. Products of snowmobile exhaust including carbon monoxide, nitrous oxides, volatile organic compounds, fine particulates, and noise …

Can Hopelessness And Adolescents’ Beliefs And Attitudes About Seeking Help Account For Help Negation?, Coralie J. Wilson Dec 2004

Can Hopelessness And Adolescents’ Beliefs And Attitudes About Seeking Help Account For Help Negation?, Coralie J. Wilson

Frank Deane

Avoidance of appropriate help is common in acutely suicidal samples and has been confirmed in nonclinical samples but factors that contribute to this help negation effect remain unclear. The current study is the second in series from the first author's larger PhD research program. In a sample of 269 nonclinical Australian high school students, the current study examines the impact of hopelessness, previous mental health care, beliefs, and attitudes toward professional psychological help on the help negation relationship. Results revealed that suicidal ideation significantly predicted lower help seeking intentions and that although hopelessness could not explain the help negation effect, …


Help Seeking For Mental Health Problems In Adolescence And Early Adulthood., Coralie J. Wilson Dec 2004

Help Seeking For Mental Health Problems In Adolescence And Early Adulthood., Coralie J. Wilson

Coralie J Wilson

EXECUTIVE SUMMARY Adolescence and young adulthood are critical life stages for mental health, as this is the period when most mental health problems and mental disorders have their peak incidence. It is also a time of increased suicidal ideation and frequency of suicide attempts. Despite the importance of adolescence and young adulthood in the aetiology of mental disorders, there is evidence that young people may be poorly informed about mental health and are unlikely to consult a professional for their mental health problems. Help-seeking is a term used to refer to the behaviour of actively seeking help from other people. …


Measuring Help-Seeking Intentions: Properties Of The General Help-Seeking Questionnaire, Coralie J. Wilson Dec 2004

Measuring Help-Seeking Intentions: Properties Of The General Help-Seeking Questionnaire, Coralie J. Wilson

Coralie J Wilson

A clear understanding of help-seeking intentions and behavior is fundamental to the identification of factors that can be modified to facilitate young people’s help-seeking when they are psychologically distressed or suicidal. Despite considerable research on help-seeking intentions and behavior for personal-emotional or distressing problems, integrating prior research has been impeded by a lack of consistent and psychometrically sound help-seeking measures. The General Help-Seeking Questionnaire (GHSQ) was developed to formally assess two aspects of help-seeking: (1) current intentions to seek help from different sources for different problems; and (2) quantity and quality of previous professional psychological helping episodes. The current study …

A Wintertime Study Of Pahs In Fine And Coarse Aerosols In Sa˜O Paulo City, Brazil, Paulo A. Lotufo Dec 2004

A Wintertime Study Of Pahs In Fine And Coarse Aerosols In Sa˜O Paulo City, Brazil, Paulo A. Lotufo

Paulo A Lotufo

The Polycyclic aromatic hydrocarbons PAHs (naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene and benzo(ghi)perylene) concentrations in fine (PM2.5) and coarse (PM2.5–10) atmospheric particulate matter were measured at Sa˜o Paulo city, Brazil. The dominant PAHcompounds were indeno(1,2,3-cd)pyrene, benzo(ghi)perylene and benzo(b)fluoranthene for both the fractions. The calculated ratios of some specific PAHs were in close agreement with those attributed to direct emissions of car exhaust. The factor analysis for PM2.5 produced four factors: Factor 1 was attributed to diesel emissions, Factor 2 was attributed to stationary combustion source, Factor 3 was attributed to vehicular emissions and Factor …


The Presence Of P22 Bacteriophage In Electrocautery Aerosols, Dale Stephenson, David Allcott, Michael Koch Mar 2004

The Presence Of P22 Bacteriophage In Electrocautery Aerosols, Dale Stephenson, David Allcott, Michael Koch

Dale J. Stephenson

Electrosurgery units, including lasers and electrosurgical cauterizers, are commonly used for both inpatient and outpatient procedures. The generation of an aerosol plume, associated with the use of these devices, is a result of many factors including: 1) direct aspiration of blood and body fluids, 2) direct heating and vaporization of cellular fluid causing cells to explode, and 3) the carbonization of cells and cell fragments at high temperatures. Although initial studies have concluded that these plumes create only a malodorous nuisance, subsequent research suggests the presence of potential chemical and pathological hazards, including bacteria and virus. Most scientific research has …


Dhandha, Dharma And Disease: Traditional Sex Work And Hiv/Aids In Rural India, J. O'Neil, Treena Orchard, J. Swarankar, J. Blanchard, K. Gurav, B. Barlaya, R. Patil, C. Hussain Khan, S. Moses Dec 2003

Dhandha, Dharma And Disease: Traditional Sex Work And Hiv/Aids In Rural India, J. O'Neil, Treena Orchard, J. Swarankar, J. Blanchard, K. Gurav, B. Barlaya, R. Patil, C. Hussain Khan, S. Moses

Dr. Treena Orchard

This paper discusses the results of two ethnographic studies with female sex workers in rural areas of Karnataka and Rajasthan, India. In particular, we focus on women whose socio-economic status, and religious and occupational practices, are part of sex work systems that have historical precedents such that they can be termed “traditional” sex workers. The approach taken in the ethnographic work was informed by current critical approaches in medical anthropology and public health. The paper argues that in the context of an expanding HIV/AIDS epidemic in rural areas of India, understanding the historical and structural factors that operate to perpetuate …

Fatal Injuries In The United States Involving Respirators, 1984-1995, Anthony Suruda, William Milliken, Dale Stephenson, Richard Sesek

Dale J. Stephenson

There is little published information concerning the epidemiology of fatal injuries involving respiratory protection. We compiled a case series from U.S. Occupational Safety and Health Administration investigation reports from 1984 through 1995. For the 12-year period there were 41 incidents resulting in 45 deaths due to asphyxiation or chemical poisoning while wearing a respirator. There were 23 deaths related to airline respirators, 17 deaths involving use of negative pressure (air purifying) respirators, and 5 deaths involving self-contained breathing apparatus. Among the 23 deaths involving airline respirators, 15 were associated with compatible connection couplings for breathable air and inert gases. Three …

En Forma Después De Los 50, Francisco Soto Mas

Francisco Soto Mas

De forma habitual uno se olvida de la salud, y sólo nos acordamos de ella cuando la echamos de menos. El trabajo, la familia y en general, la falta de tiempo son las razones esgrimidas por aquellos que no se mantienen físicamente activos. Lo recomendable es hacer ejercicio desde pequeños, pero para aquellos que llegan tarde, lo que pretendemos con este libro es concienciarles de que todavía están a tiempo de ponerse en forma. A través de una doble visión, por un lado la de la medicina y por otro la educación física, hemos intentado informar sobre las enfermedades más …


Suicidal Ideation And Help-Negation: Not Just Hopelessness Or Prior Help., Coralie Wilson Dec 2000

Suicidal Ideation And Help-Negation: Not Just Hopelessness Or Prior Help., Coralie Wilson

Coralie J Wilson

Few distressed young people seek professional psychological help and little is known about what sources of help young people seek for different problems. In suicidal youth, poor help-seeking may be exacerbated by the process of help-negation. The current study is the first of a larger program of PhD research developed and led by the second author. In the current study, three hundred and two undergraduate university students completed a questionnaire measuring suicidal ideation, hopelessness, prior help-seeking experience, and help-seeking intentions. Participants indicated they would seek help from different sources of help for different types of problems, but friends were consistently …

Adolescent Opinions About Reducing Help-Seeking Barriers And Increasing Engagement., Coralie Wilson

Coralie J Wilson

Effective mental illness prevention programs are important for the safety of youth and adolescents. Research suggests that programs should facilitate appropriate help-seeking by lowering help-seeking barriers. This study used focus groups to obtain high school student opinions about actual help-seeking behaviors, reducing adolescent help-seeking barriers, raising sensitive issues with adolescents, and increasing appropriate help-source engagement. Transcript analysis revealed several themes. Relationship and trust were key approach factors for current help-seeking. Memories of successful prior helping episodes were also important. Education about appropriate help-seeking, presented in ways consistent with those currently used by adolescents (e.g., through peer networks), might reduce help-seeking …

Alcohol Consumption And Risk Of Coronary Heart Disease By Diabetes Status, Paulo A. Lotufo Dec 1999

Alcohol Consumption And Risk Of Coronary Heart Disease By Diabetes Status, Paulo A. Lotufo

Paulo A Lotufo

Background—An inverse association between moderate alcohol consumption and coronary heart disease (CHD) has been observed in several epidemiological studies. To assess whether a similar association exists among diabetics, we examined the relation between light to moderate alcohol consumption and CHD in men with and without diabetes mellitus in a prospective cohort study. Methods and Results—A total of 87 938 US physicians (2790 with diagnosed diabetes mellitus) who were invited to participate in the Physicians’ Health Study and were free of myocardial infarction, stroke, cancer, or liver disease at baseline were followed for an average of 5.5 years for death with …

Remote Controlled Waste: Research Study Of Waste In Remote Aboriginal Communities In Central Australia For The Northern Territory Dept. Of Health And Community Services, Kurt W. Seemann, Bruce William Walker

Kurt W Seemann

One of the great challenges facing scientists, technologists, educationists and economists entering the 21st century will be to produce innovative, constructive and effective responses to unprecedented demands for comprehensive and sustainable waste management strategies. Research and development into waste management is likely to include investigations into values and ideals, population impact on land and resources, employment shifts caused by new waste processing industries, the education and economics of lifestyle changes, and the science and technologies which reduce or reprocess the range of waste a settlement produces, and the impact waste has on our health and ecology. The purposeful management of …
