Seasonal and inter-annual variation in the chlorophyll content of three co-existing Sphagnum species exceeds the effect of solar UV reduction in a subarctic peatland

Abstract: We measured chlorophyll (chl) concentration and chl a/b ratio in Sphagnum balticum, S. jensenii, and S. lindbergii, sampled after 7 and 8 years of ultraviolet-B (UVB) and temperature manipulation in an open field experiment in Finnish Lapland (68°N). We used plastic filters with different transmittance of UVB radiation to manipulate the environmental conditions. The plants were exposed to (1) attenuated UVB and increased temperature, (2) ambient UVB and increased temperature and (3) ambient conditions. Chlorophyll was extracted from the capitula of the mosses and the content and a/b ratio were measured spectrophotometrically. Seasonal variation of chlorophyll concentration in the mosses was species specific. Temperature increase to 0.5–1 °C and/or attenuation of solar UVB radiation to ca. one fifth of the ambient (on average 12 vs. 59 uW/cm2) had little effect on the chlorophyll concentration or its seasonal variation. In the dominant S. lindbergii, UVB attenuation under increased temperature led to a transient decrease in chlorophyll concentration. Altogether, species-specific patterns of seasonal chlorophyll variation in the studied Sphagna were more pronounced than temperature and UVB treatment effects.

Abstract: In recent years, webinar platforms have been broadly utilized in online learning where students meet one another synchronously online. This research’s underlying value is its recognition of the utm...

The Oligarchic Diffusion of Public Policy: Deploying the Mexican "Magic Bullet" to Combat Poverty in New York City

Abstract: Conditional cash transfer (CCT) policies are characterized as “magic bullets in development.” The New York City (NYC) CCT program, Opportunity NYC, was framed as a policy transfer experiment from Mexico’s Oportunidades. This article shows how Opportunity NYC was used to legitimate Mayor Michael Bloomberg’s power and symbolize his policy efficacy, while its private funding overrode concerns of democratic accountability. The policy rationales that justify CCTs cannot explain why particular models travel across borders, nor how such ideas are globally diffused. The case is discussed in relation to theories on diffusion of public policies and a new type, oligarchic diffusion, is proposed.

Hierarchies of knowledge: Analyzing inequalities within the social work ethnographic research process as ethical notions in knowledge production

Abstract: This article explores the link between ethical issues and inequalities in social work, ethnographic research processes. It suggests that, although the issue of inequality in social work research ha...
