Cross-Pressures and Political Participation

Early researchers of political behavior coined the term cross-pressures to describe conflicting influences on individuals\u27 political preferences, and suggested that cross-pressured citizens were less likely to participate in politics. In recent years, there has been a resurgence of interest in the relationship between cross-pressures and participation, but a lack of consensus about both the measurement of cross-pressures and their mechanisms has led to a wide array of conflicting results. We aim to bring clarity to this debate by comparing these various measures and mechanisms side-by-side, in order to better understand which pathways show the greatest potential in linking cross-pressures with participation. We consider the effect of both social cross-pressures, which stem from interactions with others in one’s social network, and issue cross-pressures, which arise from holding policy preferences across issues that do not fall along traditional ideological lines. We employ data from the 2000 US presidential election to ascertain how best to quantify each type of cross-pressures, then evaluate which proposed mechanisms show the most promise for explaining the connection between cross-pressures and participation. We find that, when modeled appropriately, both issue and social cross-pressures are associated with decreased participation. Our evidence most strongly supports the notion that both types of cross-pressures make individuals more indifferent between candidates and thus less motivated to participate, but also suggests that the potential social costs involved in more public forms of participation play a role in individuals’ calculations as well

The National Early Warning Score and its subcomponents recorded within ±24 hours of emergency medical admission are poor predictors of hospital-acquired acute kidney injury

YesBackground: Hospital-acquired Acute Kidney Injury (H-AKI) is a common cause of avoidable morbidity and mortality. Aim: To determine if the patients’ vital signs data as defined by a National Early Warning Score (NEWS), can predict H-AKI following emergency admission to hospital. Methods: Analyses of emergency admissions to York hospital over 24-months with NEWS data. We report the area under the curve (AUC) for logistic regression models that used the index NEWS (model A0), plus age and sex (A1), plus subcomponents of NEWS (A2) and two-way interactions (A3). Likewise for maximum NEWS (models B0,B1,B2,B3). Results: 4.05% (1361/33608) of emergency admissions had H-AKI. Models using the index NEWS had the lower AUCs (0.59 to 0.68) than models using the maximum NEWS AUCs (0.75 to 0.77). The maximum NEWS model (B3) was more sensitivity than the index NEWS model (A0) (67.60% vs 19.84%) but identified twice as many cases as being at risk of H-AKI (9581 vs 4099) at a NEWS of 5. Conclusions: The index NEWS is a poor predictor of H-AKI. The maximum NEWS is a better predictor but seems unfeasible because it is only knowable in retrospect and is associated with a substantial increase in workload albeit with improved sensitivity.The Health Foundatio

Beliefs about One’s Own Death, Personal Insecurity, and Materialism

The present research examined the relationship between beliefs about one’s own death and materialism. Correlational analyses revealed that concerns about one’s own death and personal insecurity were positively related to each other and with materialism. Moreover, structural equation modeling (SEM) revealed that personal insecurity partially mediated the relationship between concerns about one’s own death and materialism. We discuss the implications of personal insecurity as an antecedent of materialism and the importance of including it as a potential mediator in future investigations of materialism. We also illuminate potential counseling implications of our findings

Anosognosia predicts default mode network hypometabolism and clinical progression to dementia

ObjectiveTo identify the pathophysiologic mechanisms and clinical significance of anosognosia for cognitive decline in mild cognitive impairment.MethodsWe stratified 468 patients with amnestic mild cognitive impairment into intact and impaired awareness groups, determined by the discrepancy between the patient and the informant score on the Everyday Cognition questionnaire. Voxel-based linear regression models evaluated the associations between self-awareness status and baseline β-amyloid load, measured by [18F]florbetapir, and the relationships between awareness status and regional brain glucose metabolism measured by [18F]fluorodeoxyglucose at baseline and at 24-month follow-up. Multivariate logistic regression tested the association of awareness status with conversion from amnestic mild cognitive impairment to dementia.ResultsWe found that participants with impaired awareness had lower [18F]fluorodeoxyglucose uptake and increased [18F]florbetapir uptake in the posterior cingulate cortex at baseline. In addition, impaired awareness in mild cognitive impairment predicted [18F]fluorodeoxyglucose hypometabolism in the posterior cingulate cortex, left basal forebrain, bilateral medial temporal lobes, and right lateral temporal lobe over 24 months. Furthermore, participants with impaired awareness had a nearly 3-fold increase in likelihood of conversion to dementia within a 2-year time frame.ConclusionsOur results suggest that anosognosia is linked to Alzheimer disease pathophysiology in vulnerable structures, and predicts subsequent hypometabolism in the default mode network, accompanied by an increased risk of progression to dementia. This highlights the importance of assessing awareness of cognitive decline in the clinical evaluation and management of individuals with amnestic mild cognitive impairment
