Methods: We conducted a cross-sectional study of 192 men from subfertile couples. We used multiprobe fluorescence in situ hybridization (FISH) for chromosomes X, Y, and 18 to determine XX, YY, XY, and total sex-chromosome disomy in sperm nuclei. Serum was analyzed for concentrations of 57 PCB congeners and p,p´-DDE. Poisson regression models were used to calculate incidence rate ratios (IRRs) for …

An Inconvenient Lie: Big Tobacco Was Put On Trial For Denying The Effects Of Smoking; Is Climate Change Denial Off-Limits?, Elizabeth Dubats

Northwestern Journal of Law & Social Policy

Plaintiffs have made several notable attempts to bring nuisance, trespass, and negligence suits against major sources of greenhouse gas emissions for climate change related injuries. While climate change is a widely recognized environmental issue, courts have refused to recognize it as a basis for a valid cause of action in tort, finding either petitioners lack standing to bring the claim, or that the claim raises political questions that should not be addressed by the judiciary. Some more recent climate change tort claims have also included allegations of fraud on the part of the hydrocarbon industry for actively perpetuating misinformation about …

Road Construction As A Facilitator For Dengue Fever Transmission, Kate Billups

Environmental Studies Senior Seminar Projects

Although I plan to focus on the impact of road construction in tropical and subtropical regions on the spread and contraction of dengue fever, I hope to use this focus as a model that could help to create policies that would mitigate other diseases spread through insect contact. In places that road and railway construction have already become a part of the permanent foundation, medical infrastructure should be put into place to ensure that populations at increased risk to contract dengue fever have access to medical care to diminish rates of dengue hemorrhagic fever.

The Influence Of Neighborhood Characteristics On The Existence Of Asthma In Children, Elizabeth Adejuyigbe

Annual Undergraduate Conference on Health and Society

Asthma is one of the leading chronic diseases in children 17 years of age and under with nine million American children suffering from it. Previous studies to understand causal factors of disease including asthma tend to focus on the individual and sociocultural characteristics but there is little to no research using neighborhood characteristics, a factor that does influence health. Research shows that other community‐level environmental factors like collective efficacy, community structural factors, and neighborhood safety can affect a persons’ psychosocial well-being, and in turn increase morbidity. For this reason, researchers suggest that the need to understand asthma and its associated …

Methods: This is a retrospective study and secondary data analysis of the 2000 National Health Interview Survey. Parametric testing using Univariate/Bivariate/Multivariate analysis …

Asthma Management: An Ecosocial Framework For Disparity Research, Robin A. Evans-Agnew

Journal of Health Disparities Research and Practice

Background: Asthma management disparities (AMD) between African and White Americans are significant and alarming. Various determinants have been suggested by research frameworks that affect the unfair distribution of resources for asthma management to groups who are more or less advantaged socially. Ecosocial models organize determinants into individual/family, healthcare, community, and sociocultural levels. Multilevel interventions can affect AMD through simultaneous actions on different levels and pathways between determinants.

Objective: Provide a comprehensive summary of the known determinants of AMD.

Method: Peer reviewed research frameworks of AMD from 1998-2009 were retrieved from PubMed/ Web of Science databases using (“Socioeconomic Factors”[Mesh] OR (“Healthcare …

Influence Of Ph On The Transport Of Silver Nanoparticles In Saturated Porous Media: Laboratory Experiments And Modeling, Jason R. Flory

Theses and Dissertations

Given the ubiquity of silver nanoparticles (AgNPs), the largest and fastest growing category of nanomaterials, and their potential for toxic effects to both humans and the environment, it is important to understand their environmental fate and transport. The purpose of this study is to gain information on the transport properties of unmodified AgNP suspensions in a glass bead-packed column under saturated flow conditions at different solution pH levels. Commercial AgNPs were characterized using high resolution transmission spectroscopy (HRTEM), dynamic light scattering (DLS) and ultraviolet (UV) visible spectroscopy. Transport data were collected at different pH levels (4, 6.5 and 9) at …

From Service Provision To Function Based Performance - Perspectives On Public Health Systems From The Usa And Israel, F. Douglas Scutchfield, Ehud Miron, Richard Ingram

Preventive Medicine and Environmental Health Faculty Publications

If public health agencies are to fulfill their overall mission, they need to have defined measurable targets and should structure services to reach these targets, rather than offer a combination of ill-targeted programs. In order to do this, it is essential that there be a clear definition of what public health should do- a definition that does not ebb and flow based upon the prevailing political winds, but rather is based upon professional standards and measurements.

The establishment of the Essential Public Health Services framework in the U.S.A. was a major move in that direction, and the model, or revisions …
