For this Discussion, you will evaluate the purpose statements in assigned journal articles in your discipline and consider the alignment of theory, problem, and purpose. You will also explain your position on the relationship between research and social change.Alignment means that a research study possesses clear and logical connections among all of its various components. To achieve these connections, researchers must carefully craft the components of their study such that when they are viewed together, there is a coherent interrelationship.As you read the authors’ purpose statements, consider how well the intent of the study, and its connection to the problem and theoretical framework, is presented. Also, consider if the purpose statement reveals the study’s potential for engendering positive social change.As you know, social change is a distinguishing feature of Walden University’s mission. Positive social change implies a transformation that results in positive outcomes. This can happen at many levels (e.g., individual, family systems, neighborhoods, organizations, nationally and globally); and positive social change can occur at different rates: slow and gradual or fast and radical.Journal ArticleWilhelmy, A., Kleinmann, M., König, C.
