Shades of Privilege: The Relationship Between Skin Color and Political Attitudes Among White Americans

Shades of Privilege: The Relationship Between Skin Color and Political Attitudes Among White Americans

AdvertisementShifting racial dynamics in the U.S. have heightened the salience of White racial identity, and a sense that Whites’ social status and resources are no longer secure. At the same time, the growing size of non-White populations has also renewed attention to skin color-based stratification and the potential blurring of racial boundaries. We theorize that Whites with darker skin will be motivated to protect the boundaries of Whiteness due to the loss of status they would face from blurring racial boundaries. Consistent with growing evidence of skin color’s importance for Whites,...

Analysis of Austrian COVID-19 deaths by age and sex

Analysis of Austrian COVID-19 deaths by age and sex

AdvertisementAnalysis of Austrian COVID-19 deaths by age and sexWe analyze the age and sex distribution of the reported COVID-19 deaths in Austria. In accordance with international studies, the Austrian data also suggests that the risk of death increases substantially with age. The observed age dependency of the proportions of registered COVID-19 deaths in relation to the population sizes in the age groups is approximately exponential, similar to the age dependency of the general age specific mortality rate. Furthermore, we compare the general age specific mortality rate in Austria with the...

Macroglial diversity: white and grey areas and relevance to remyelination

AdvertisementMacroglial diversity: white and grey areas and relevance to remyelinationMacroglia, comprising astrocytes and oligodendroglial lineage cells, have long been regarded as uniform cell types of the central nervous system (CNS). Although regional morphological differences between these cell types were initially described after their identification a century ago, these differences were largely ignored. Recently, accumulating evidence suggests that macroglial cells form distinct populations throughout the CNS, based on both functional and morphological features. Moreover, with the...

The academic Trumpists: American professors who support the Trump presidency

The academic Trumpists: American professors who support the Trump presidency

AdvertisementThe Trump presidency has been remarkable in its attacks on many mainstream institutions. It has tapped populist sentiment that reflects little confidence in the key decision-making centers in American society. Higher education has not escaped this attack. Indeed, criticism of the academy has gone well beyond the debated policies of affirmative action and political correctness to the very status of expert knowledge itself, questioning what is legitimate knowledge. Claims of “false data” and “alternative facts” parade in the public arena without the benefit of reasoned...

Localized States in Quantum Field Theory

Localized States in Quantum Field Theory

AdvertisementLocalized states in relativistic quantum field theories are usually considered as problematic, because of their seemingly strange (noncovariant) behavior under Lorentz transformations, and because they can spread faster than light. We point out that a careful quantum field theoretic analysis in which we distinguish between basis position states and wave packet states clarifies the issue of Lorentz covariance. The issue of causality is resolved by observing that superluminal transmission of information cannot be achieved by such wave packets. Within this context it follows that...

Muscular Thin Films for Label-Free Mapping of Excitation Propagation in Cardiac Tissue

Muscular Thin Films for Label-Free Mapping of Excitation Propagation in Cardiac Tissue

AdvertisementMuscular thin films (MTFs), have already found a variety of applications in cardiac tissue engineering and in building of lab-on-a-chip systems. Here we present a novel approach to label-free mapping of excitation waves in the cardiomyocyte cell cultures with the use of MTFs. Neonatal rat ventricular cardiomyocytes were cultured on polydimethylsiloxane (PDMS) thin films and observed by means of off-axis illumination. Inflexions of the membrane created by the contraction of cardiomyocytes led to formation of patterns of bright and dark areas on the surface of the membrane. These...

Labor Unions and White Democratic Partisanship

AdvertisementHelp us understand how you use our websites.The Democratic Party’s declining support among white voters is a defining feature of contemporary American politics. Extant research has emphasized factors such as elite polarization and demographic change but has overlooked another important trend, the decades-long decline of labor union membership. This oversight is surprising, given organized labor’s long ties to the Democratic Party. I argue that the concurrent decline of union membership and white support for the Democratic Party is not coincidental, but that labor union...
