Young African American Men's Conception Of Fatherhood Among Survivors Of Childhood Abuse, Ohan Patricia Carter Jan 2020

Young African American Men's Conception Of Fatherhood Among Survivors Of Childhood Abuse, Ohan Patricia Carter

Walden Dissertations and Doctoral Studies

Male survivors of abuse who become fathers themselves face challenges different from female survivors, such as conceptualizing their roles as providers and heads of households after the traumatic and often belittling experiences of abuse. However, very few researchers have studied the connection between child abuse and fatherhood, and none specific to young African American fathers. An interpretative phenomenological approach enabled exploration of how African American fathers who were abused as children, conceptualized and perceived their own experiences with fatherhood. The theoretical framework for this study was identity theory, which indicates that how people conceptualize a social role influences their actions ...


Pertussis Resurgence In Europe: Incidence And Epidemiologic Cycles In Immunization Required And Non-Required Countries, Sheryl Ann Duquet Jan 2020

Pertussis Resurgence In Europe: Incidence And Epidemiologic Cycles In Immunization Required And Non-Required Countries, Sheryl Ann Duquet

Walden Dissertations and Doctoral Studies

Although pertussis vaccines have been available for over 7 decades, countries are experiencing a pertussis resurgence. This study sought to establish a relationship between the European pertussis immunization schedule designs (with and without the inclusion of adolescent boosters) and the immunization requirement (recommended or required), which potentially influences immunity waning, and thus the incidence rate and epidemiologic cycles of pertussis. The theoretical foundation for this study was the theory of herd immunity. A quantitative research method was used, supported by a secondary data source. The statistical analysis included the use of linear regression to evaluate the relationship between the requirement ...

Association Between Maoa U Vntr Genetic Polymorphism And Aggression, Gender, And Race In Adolescents, Almaz Adair Johnson Jan 2020

Association Between Maoa U Vntr Genetic Polymorphism And Aggression, Gender, And Race In Adolescents, Almaz Adair Johnson

Walden Dissertations and Doctoral Studies

A genetic polymorphism found in the upstream region of the monoamine oxidase A (MAOA) gene upstream variable number tandem repeat (u VNTR) has been shown to have an influence on aggression with mixed results. The purpose of this quantitative study was to examine the association between the u VNTR genetic polymorphism of the MAOA gene and aggression in an adolescent population 13–18 years of age. The conceptual framework was based on the biosocial model of antisocial behavior that indicates genes can influence aggressive behaviors with or without environmental influences. Data (N = 2506) from the National Longitudinal Adolescents and Adult ...


Microcystins And Liver Disease Mortality, Insights From An Ecological Study, Rajesh Tirpaul Melaram Jan 2020

Microcystins And Liver Disease Mortality, Insights From An Ecological Study, Rajesh Tirpaul Melaram

Walden Dissertations and Doctoral Studies

Microcystins (MCs) are toxic secondary metabolites produced by freshwater cyanobacteria. Algal bloom subsidence can stimulate MC release, which can impair liver function if orally exposed to in large doses. The purpose of this retrospective, U.S. ecological study was to determine if MC exposure represented an environmental risk factor for liver disease mortality using a socioecological approach. A longitudinal ecological substudy investigated the association between average total MCs in Lake Washington and Lake Manatee and age-adjusted chronic liver disease (CLD)/cirrhosis death rates in Brevard County and Manatee County, Florida (FL). A prediction model of total MCs was deduced by ...
