Examining the Influence of Political Affiliation and Orientation on Political Tolerance

Political identities are strongly associated with political tolerance. Specifically, previous research shows that American liberals report higher levels of tolerance toward marginalized groups than conservatives. Political orientation, however, varies more among Democrats than Republicans, which might mean that Democrats are relatively diverse in their levels of political tolerance. In this article, the authors ask how the association between political orientation and political tolerance varies across political parties. Using General Social Survey data, the authors find that tolerance is highest among liberals, followed by moderates and conservatives. Regression models with interactions between party and orientation demonstrate that political orientation is consequential for tolerance levels among independents, and especially Democrats, but is far less so for Republicans. Additional analyses demonstrate how the party-contingent association between political orientation and tolerance varies by the outgroup in question. This research demonstrates the complexity of political dimensions when considering support for the rights of marginalized outgroups

The Diffusion of Tolerance: Birth Cohort Changes in the Effects of Education and Income on Political Tolerance

Political tolerance—the willingness to extend civil liberties to traditionally stigmatized groups—is pivotal to the functioning of democracy and the well-being of members of stigmatized groups. Although political tolerance has traditionally been more common among American elites, we argue that as tolerance has increased, it has also diffused to less educated and less affluent segments of the population. The relative stability of political attitudes over the life course and the socialization of more recent birth cohorts in contexts of increased tolerance suggest that this diffusion of tolerance occurs across birth cohorts rather than time periods. Using age-period-cohort models and more than three and a half decades of repeated cross-sectional survey data, we find persistent and robust across-cohort declines in the importance of both income and higher education in determining levels of political tolerance. Declines in the effects of socioeconomic status are evident with tolerance toward all five out-groups in the analysis—anti-religionists, gays and lesbians, communists, militarists, and racists—but to varying degrees. These findings fit with a model of changes in public opinion, particularly views of civil and political rights, through processes of cultural diffusion and cohort replacement

From Sea to Sea: Canada's Three Oceans of Biodiversity

Evaluating and understanding biodiversity in marine ecosystems are both necessary and challenging for conservation. This paper compiles and summarizes current knowledge of the diversity of marine taxa in Canada's three oceans while recognizing that this compilation is incomplete and will change in the future. That Canada has the longest coastline in the world and incorporates distinctly different biogeographic provinces and ecoregions (e.g., temperate through ice-covered areas) constrains this analysis. The taxonomic groups presented here include microbes, phytoplankton, macroalgae, zooplankton, benthic infauna, fishes, and marine mammals. The minimum number of species or taxa compiled here is 15,988 for the three Canadian oceans. However, this number clearly underestimates in several ways the total number of taxa present. First, there are significant gaps in the published literature. Second, the diversity of many habitats has not been compiled for all taxonomic groups (e.g., intertidal rocky shores, deep sea), and data compilations are based on short-term, directed research programs or longer-term monitoring activities with limited spatial resolution. Third, the biodiversity of large organisms is well known, but this is not true of smaller organisms. Finally, the greatest constraint on this summary is the willingness and capacity of those who collected the data to make it available to those interested in biodiversity meta-analyses. Confirmation of identities and intercomparison of studies are also constrained by the disturbing rate of decline in the number of taxonomists and systematists specializing on marine taxa in Canada. This decline is mostly the result of retirements of current specialists and to a lack of training and employment opportunities for new ones. Considering the difficulties encountered in compiling an overview of biogeographic data and the diversity of species or taxa in Canada's three oceans, this synthesis is intended to serve as a biodiversity baseline for a new program on marine biodiversity, the Canadian Healthy Ocean Network. A major effort needs to be undertaken to establish a complete baseline of Canadian marine biodiversity of all taxonomic groups, especially if we are to understand and conserve this part of Canada's natural heritage

PERCEIVED STIGMA AND STIGMA MANAGEMENT OF MIDWEST SECULARS

Prior work demonstrates that atheists and other secular individuals experience especially low trust among the American public. This line of research suggests that those with no religious belief encounter societal stigma related to their non-belief. Yet it is unknown how non-believers perceive and manage stigma. I explore perceived stigma and stigma management strategies employed by atheists, agnostics, and other secular individuals in the Midwest using a mixed methods approach. Results from survey data from more than 2,200 secular individuals as well as 24 in-depth interviews with seculars living in the Midwest show that prejudice and discrimination are common experiences for these individuals. Furthermore, perceived stigma is positively correlated with utilization of secretive and especially proactive stigma management strategies. Additionally, I examine how perceived stigmatization of secular individuals in the Midwest relates to their psychological distress. Results from mixed methods analyses show that perceived secular stigma is associated with distress related to having a secular status. This research is important because it provides a context for the consequences of having a secular status in a predominantly religious society

A database and synthesis of northern peatland soil properties and Holocene carbon and nitrogen accumulation

Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45 degrees N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan Plateau. For all northern peatlands, carbon content in organic matter was estimated at 42 +/- 3% (standard deviation) for Sphagnum peat, 51 +/- 2% for non-Sphagnum peat, and at 49 +/- 2% overall. Dry bulk density averaged 0.12 +/- 0.07 g/cm(3), organic matter bulk density averaged 0.11 +/- 0.05 g/cm(3), and total carbon content in peat averaged 47 +/- 6%. In general, large differences were found between Sphagnum and non-Sphagnum peat types in terms of peat properties. Time-weighted peat carbon accumulation rates averaged 23 +/- 2 (standard error of mean) g C/m(2)/yr during the Holocene on the basis of 151 peat cores from 127 sites, with the highest rates of carbon accumulation (25-28 g C/m(2)/yr) recorded during the early Holocene when the climate was warmer than the present. Furthermore, we estimate the northern peatland carbon and nitrogen pools at 436 and 10 gigatons, respectively. The database is publicly available at https://peatlands.lehigh.edu
