Global dataset of soil organic carbon in tidal marshes.

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil organic carbon (SOC) stocks provide an important resource for researchers, natural resource managers, and policy-makers working towards the protection, restoration, and valuation of these ecosystems. We collated a global dataset of tidal marsh soil organic carbon (MarSOC) from 99 studies that includes location, soil depth, site name, dry bulk density, SOC, and/or soil organic matter (SOM). The MarSOC dataset includes 17,454 data points from 2,329 unique locations, and 29 countries. We generated a general transfer function for the conversion of SOM to SOC. Using this data we estimated a median (± median absolute deviation) value of 79.2 ± 38.1 Mg SOC ha-1 in the top 30 cm and 231 ± 134 Mg SOC ha-1 in the top 1 m of tidal marsh soils globally. This data can serve as a basis for future work, and may contribute to incorporation of tidal marsh ecosystems into climate change mitigation and adaptation strategies and policies

Spatial heterogeneity and environmental predictors of permafrost region soil organic carbon stocks

Large stocks of soil organic carbon (SOC) have accumulated in the Northern Hemisphere permafrost region, but their current amounts and future fate remain uncertain. By analyzing dataset combining >2700 soil profiles with environmental variables in a geospatial framework, we generated spatially explicit estimates of permafrost-region SOC stocks, quantified spatial heterogeneity, and identified key environmental predictors. We estimated that Pg C are stored in the top 3 m of permafrost region soils. The greatest uncertainties occurred in circumpolar toe-slope positions and in flat areas of the Tibetan region. We found that soil wetness index and elevation are the dominant topographic controllers and surface air temperature (circumpolar region) and precipitation (Tibetan region) are significant climatic controllers of SOC stocks. Our results provide first high-resolution geospatial assessment of permafrost region SOC stocks and their relationships with environmental factors, which are crucial for modeling the response of permafrost affected soils to changing climate

Nostalgic nationalism, welfare chauvinism, and migration anxieties in Central and Eastern Europe

This contribution examines, in the Central and Eastern European context, the interplay between ideals of national specificity, welfare chauvinist appeals, and emerging politics of migration, for the purpose of providing welfare provision to a narrowly defined ethnic group, as promoted by right-wing populist parties in the region. We suggest a comparative framework to account the various positions that such parties occupy in the mainstream political systems in Central and Eastern Europe. Our study deals with the case of a right-wing populist party becoming the main governing force, such as the Law and Justice Party (Prawo i Sprawiedliwość, PiS) in Poland; the case of a right-wing populist party as key opposition force, such as the Movement for a Better Hungary (Jobbik Magyarországért Mozgalom, Jobbik) in Hungary; and thirdly, the case of an unsuccessful right-wing populist party, such as the United Romania Party (Partidul România Unită, PRU). For our qualitative analysis we are drawing on the official discourses of these parties as articulated from 2015 onwards, since it marks the beginning of what has come to be referred to as the European refugee crisis. The aim of this chapter is to map out the various electoral strategies employed, with varying degrees of success, which juxtapose cultural protectionist appeals to welfare chauvinist proposals, and consequently shed light on the culture and welfare nexus in the Central and Eastern European context

Assembly and function of the Photosystem II manganese stabilizing protein: lessons from its natively unfolded behavior

The Photosystem II (PS II) manganese stabilizing protein (MSP) possesses characteristics, including thermostability, ascribed to the natively unfolded class of proteins (Lydakis-Simantiris et al. (1999) Biochemistry 38: 404–414). A site-directed mutant of MSP, C28A, C51A, which lacks the -S–S- bridge, also binds to PS II at wild-type levels and reconstitutes oxygen evolution activity [Betts et al. (1996) Biochim Biophys Acta 1274: 135–142], although the mutant protein is even more disordered in solution. Both WT and C28A, C51A MSP aggregate upon heating, but an examination of the effects of protein concentration and pH on heat-induced aggregation showed that each MSP species exhibited greater resistance to aggregation at a pH near their p I (5.2) than do either bovine serum albumin (BSA) or carbonic anhydrase, which were used as model water soluble proteins. Increases in pH above the p I of the MSPs and BSA enhanced their aggregation resistance, a behavior which can be predicted from their charge (MSP) or a combination of charge and stabilization by -S–S- bonds (BSA). In the case of aggregation resistance by MSP, this is likely to be an important factor in its ability to avoid unproductive self-association reactions in favor of formation of the protein–protein interactions that lead to formation of the functional oxygen evolving complex.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43544/1/11120_2004_Article_7759.pd

Mbs Experimental Digital Radio-Camera Trials

Electronic news gathering and live outside broadcasts need a quick and easy method of getting the programme material back to base. The success of mobile telephones has encouraged the telecommunications industry to develop more advanced systems offering higher capacities. Mobile Broadband System (MBS) is a wireless cellular radio network supporting services up to 34 Mbits/s. The network is being developed in a European collaborative project called SAMBA, which is constructing a trial platform consisting of two radio cells and a person-portable mobile for a wireless digital camera. These radio cells operate at 40 GHz and can be deployed to fit the coverage requirements in various short-range applications both indoors and outdoors. Switching the radio signal between the cells is automatic, allowing the camera operator to concentrate on framing the shots. The system is undergoing assembly and testing and then demonstrations will be carried out in September at Expo '98 in Lisbon, followed b..

Collaboration and relationship building in Aboriginal and Torres Strait Islander Social Work

This chapter explores what it means to work collaboratively in Aboriginal and Torres Strait Islander social work, and to situate collaboration as key to the development and articulation of social work practice with Aboriginal and Torres Strait Islander people. The aim is to develop the capacity for workers in social work and the human services from different cultural backgrounds and service contexts to establish purposeful and respectful working relationships with each other and with Aboriginal and Torres Strait Islander people, leaders and Elders, communities and services in order to achieve common goals. One of the assumptions underpinning this chapter is that the values, skills, knowledge and protocols that inform collaborative work, relationship building and the development of partnerships are all essential for culturally respectful and effective social work. Fundamentally, this means acknowledging the colonial practices that have shaped and continue to influence the Australian social work profession. The second assumption is that non-Indigenous social workers do have an important role to play in Aboriginal and Torres Strait Islander social work, but in order to do this effectively there is a need to work in partnership with Aboriginal and Torres Strait Islander people. Having the capacity to work together reflects the social justice and human rights foundations of our profession. The power of collaboration can lead to significant change and capacity building for all workers, communities and services. These skills and values are transferable to all practice contexts and groups
