AbstractFor adequate modeling of missing responses, a thorough understanding of the nonresponse mechanisms is vital. As a large number of major testing programs are in the process or already have been moving to computer-based assessment, a rich body of additional data on examinee behavior becomes easily accessible. These additional data may contain valuable information on the processes associated with nonresponse. Bringing together research on item omissions with approaches for modeling response time data, we propose a framework for simultaneously modeling response behavior and omission behavior utilizing timing information for both. As such, the proposed model allows (a) to gain a deeper understanding of response and nonresponse behavior in general and, in particular, of the processes underlying item omissions in LSAs, (b) to model the processes determining the time examinees require to generate a response or to omit an item, and (c) to account for nonignorable item omissions. Parameter recovery of the proposed model is studied within a simulation study. An illustration of the model by means of an application to real data is provided. 相似文献

AbstractThis article examines several aspects of knowledge production among practitioners of 21st century capitalism, critiquing the motivations, funding, methods, and dissemination of today’s politically and economically dominant epistemology. We document a methodological experiment undertaken during the Oregon Eclipse Festival—a week-long event coinciding with the solar eclipse that crossed the United States on August 21, 2017. As commissioned participants in the festival’s Art & Science exhibit, we designed an interactive archeological excavation that sought to produce material evidence corroborating the (un)reality of UFO activity in Oregon. From this performance, we highlight four insights into the relationship between science, evidence, and responsibility. 相似文献

ABSTRACTRelative deprivation theory suggests that discrimination increases the risk of violence. While religious armed conflicts have been increasing in sub-Saharan Africa, effects of religious discrimination have rarely been investigated. Using the new Religion and State dataset and other sources, this contribution investigates this question in a two-level analysis. The analysis yields three main results. First, religious discrimination has been increasing over the last 15 years but in interregional comparison sub-Saharan Africa has a low level of discrimination. Second, at the cross-country level there is a significant correlation between religious discrimination and armed conflict over religious content. Third, looking closer at four pertinent country cases (the Comoros, the Gambia, Mali and Mauritania) reveals that discrimination is probably not a direct driver of religious conflicts. High levels of discrimination are embedded in problematic state-religion relations and existing cleavages become mobilised along religious lines through transnational influences and geography. 相似文献
