Evidence for validity and scale reliability was collected for the ASCS with this novel population and a range of motivational and self-regulative variables (Goal orientation, academic emotion regulation, and lifelong learning) were analyzed …

The Intersection Of Economic Disadvantage And Race And The Expanded Role Of Parent-Led School-Supporting Nonprofit Organizations In K-12 Public Schools In The Richmond, Virginia, Metropolitan Area: A Mixed Methods Approach, Rachel A. Levy

Theses and Dissertations

Nongovernmental actors have long been involved in the funding of U.S. K-12 public schools. With recent cuts to state funding to public education, however, groups called school-supporting nonprofits (Nelson & Gazley, 2014) have taken on a much larger role in school funding. Nonacademic, volunteer, parent-led groups such as parent teacher associations (PTAs), parent teacher organizations (PTOs), and booster clubs, especially, have grown in number and in amount of revenues raised, and are funding core school needs and functions. This situation confuses obligations of public institutions, undermines equity, and complicates the role of educational leaders. This mixed-methods study explores the influence …

The Political Nature Of The Paris Commune Of 1871 And Manifestations Of Marxist Ideology In The Official Publications Of The Central Committee, Emily M. Jones

Theses and Dissertations

Historians originally claimed that the 1871 Paris Commune was inspired by Karl Marx. Since the 1960s, however, this assertion has been rejected by scholars who either claim that Marx had no influence over the Paris Communards or do not address the possibility that this influence existed. Many scholars have also claimed that the Commune was not political in any way, but was a rebellion inspired by patriotism, bitterness for the Versailles government’s capitulation of Paris to Prussia, or a spontaneous reaction to hostility from the national army’s attempt to disarm the indignant, rapidly organizing Parisian workers who called for municipal …

Development Of Novel Models To Study Deep Brain Effects Of Cortical Transcranial Magnetic Stimulation, Farheen Syeda

Theses and Dissertations

Neurological disorders require varying types and degrees of treatments depending on the symptoms and underlying causes of the disease. Patients suffering from medication-refractory symptoms often undergo further treatment in the form of brain stimulation, e.g. electroconvulsive therapy (ECT), transcranial direct current stimulation (tDCS), deep brain stimulation (DBS), or transcranial magnetic stimulation (TMS). These treatments are popular and have been shown to relieve various symptoms for patients with neurological conditions. However, the underlying effects of the stimulation, and subsequently the causes of symptom-relief, are not very well understood. In particular, TMS is a non-invasive brain stimulation therapy which uses time-varying magnetic …

Modulation Of Electron Transport By Metformin In Cardiac Protection: Role Of Complex I, Ahmed Abdul Hussein Mohsin

Theses and Dissertations

Modulation of mitochondrial complex I during reperfusion reduces cardiac injury. Complex I exists in two structural states: active (A) and deactive (D) with transition from A→D during ischemia. Reperfusion reactivates D→A with an increase in ROS production. Metformin preserves the D-Form. Our aim was to study the contribution of maintenance of deactivation of complex I during early reperfusion by metformin to protect against ischemia reperfusion injury. Our results showed that metformin decreased H9c2 cardiomyoblast apoptosis and total cell death following simulated ischemia for six hours followed by reoxygenation for twenty four hours compared to untreated cells. Reactive oxygen species (ROS) …

Normative Data For Four Neuropsychological Tests In A Sample Of Adults Who Are Illiterate And From Latin America, Alejandra Morlett Paredes

Theses and Dissertations

Neuropsychological tests are standardized tasks used to measure psychological functioning that is associated with a particular brain structure. These tests often are used in diagnosing a cognitive deficiency resulting from brain injuries. Currently, there are a limited number of studies that have focused on standardization of neuropsychological tests in Latin America. Therefore, the vast majority of cognitive tests used in the evaluation of patients with brain damage have no normative parameters adjusted to the cultural characteristics of Latinos and Latinas. As a result, neuropsychological diagnoses among this population may be inadequate, and evaluation of rehabilitation program effectiveness limited. The importance …
