Americans At Heart But Not On Paper: A Normative Study of Amnesty in U.S. Immigration Politics

The initiative Deferred Action for Childhood Arrivals is an example of the use of amnesty within American immigration politics. Enacted in June 2012, it addresses the delicate situation of young undocumented immigrants so called childhood arrivals. They are part of the society in many ways, but not on paper. The dilemma is characterized by a conflict of interest – the rights of the sovereign state

Governing the transition to low-carbon futures: A critical survey of energy scenarios for 2050

There is a growing scientific consensus that limiting the increase in global average temperature to around 2 C above pre-industrial levels is necessary to avoid unacceptable impact on the climate system. This requires that the developed countries' emissions are radically reduced during the next 40 years. Energy scenario studies provide insights on the societal transitions that might be implied by

New insights on resource stoichiometry: assessing availability of carbon, nitrogen, and phosphorus to bacterioplankton

Boreal lake and river ecosystems receive large quantities of organic nutrients and carbon (C) from their catchments. How bacterioplankton respond to these inputs is not well understood, in part because we base our understanding and predictions on total pools, yet we know little about the stoichiometry of bioavailable elements within organic matter. We designed bioassays with the purpose of exhaust

An Architecture for Resource Bounded Agents

We study agents situated in partially observable environments, who do not have sufficient resources to create conformant (complete) plans. Instead, they create plans which are conditional and partial, execute or simulate them, and learn from experience to evaluate their quality. Our agents employ an incomplete symbolic deduction system based on Active Logic and Situation Calculus for reasoning abo

The Interdependence between Rainfall and Temperature: Copula Analyses

Rainfall and temperature are important climatic inputs for agricultural production, especially in the context of climate change. However, accurate analysis and simulation of the joint distribution of rainfall and temperature are difficult due to possible interdependence between them. As one possible approach to this problem, five families of copula models are employed to model the interdependence

A 2-year follow-up study of people with severe mental illness involved in psychosocial rehabilitation

Backgrounds. A focus on psychiatric rehabilitation in order to support recovery among persons with severe mental illness (SMI) has been given great attention in research and mental health policy, but less impact on clinical practice. Despite the potential impact of psychiatric rehabilitation on health and wellbeing, there is a lack of research regarding the model called the Psychiatric Rehabilitat

Phylogenetic Analysis Suggests That Habitat Filtering Is Structuring Marine Bacterial Communities Across the Globe.

The phylogenetic structure and community composition were analysed in an existing data set of marine bacterioplankton communities to elucidate the evolutionary and ecological processes dictating the assembly. The communities were sampled from coastal waters at nine locations distributed worldwide and were examined through the use of comprehensive clone libraries of 16S ribosomal RNA genes. The ana

Structuring Sustainability Science

It is urgent in science and society to address climate change and other sustainability challenges such as biodiversity loss, deforestation, depletion of marine fish stocks, global ill-health, land degradation, land use change and water scarcity. Sustainability science (SS) is an attempt to bridge the natural and social sciences for seeking creative solutions to these complex challenges. In this ar

The eco-evolutionary consequences of interspecific phenological asynchrony - a theoretical perspective

The timing of biological events (phenology) is an important aspect of both a species' life cycle and how it interacts with other species and its environment. Patterns of phenological change have been given much scientific attention, particularly recently in relation to climate change. For pairs of interacting species, if their rates of phenological change differ, then this may lead to asynchrony b

Within-bloom shift in abundance of a wild pollinator mediates pollen deposition rates to blueberry

Intra-seasonal variation in abiotic and biotic conditions can have profound consequences for pollinator community compositions and foraging movement, with flow-on effects upon pollination services. Yet, few studies have related such variations to pollination services in crop systems. In a cultivated highbush blueberry system with two primary pollinators — the managed European honey bee and a wild

National records of 3000 European bee and hoverfly species : A contribution to pollinator conservation

Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental levels is needed to implement efficient conservation actions, but this knowledge is still fragmented and/or difficult to access. As a step forward, we provide an updated list of aroun

Inconsistent responses of carabid beetles and spiders to land-use intensity and landscape complexity in north-western Europe

Reconciling biodiversity conservation with agricultural production requires a better understanding of how key ecosystem service providing species respond to agricultural intensification. Carabid beetles and spiders represent two widespread guilds providing biocontrol services. Here we surveyed carabid beetles and spiders in 66 winter wheat fields in four northwestern European countries and analyze

Species distributions models may predict accurately future distributions but poorly how distributions change : A critical perspective on model validation

Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been eva

The Structure of Evolutionary Theory : Beyond Neo-Darwinism, Neo-Lamarckism and Biased Historical Narratives About the Modern Synthesis

The last decades have seen frequent calls for a more extended evolutionary synthesis (EES) that will supposedly overcome the limitations in the current evolutionary framework with its intellectual roots in the Modern Synthesis (MS). Some radical critics even want to entirely abandon the current evolutionary framework, claiming that the MS (often erroneously labelled “Neo-Darwinism”) is outdated, a

Deliberating a Sustainable Welfare–Work Nexus / Auf dem Weg zu einem nachhaltigen Wohlfahrt-Arbeit-Nexus

Very few countries have managed to decouple economic growth from resource use and greenhouse gas emissions in absolute terms and at rates to meet the climate targets of the Paris Agreement. To achieve this, technological solutions would need to be combined with sufficiency-oriented policies in a postgrowth context. This paper develops policy ideas for a sustainable welfare–work nexus via citizen e

Microbial gene activity in straw residue amendments reveals carbon sequestration mechanisms in agricultural soils

Land-use practices and their intensity along with climatic conditions alter amounts of soil organic carbon content and consequently influence soil microorganisms. However, land-use management, such as crop residue incorporation to soils has a potential to mitigate losses of soil organic carbon and thereafter promote the diversity of soil microorganisms. To gain insight of microbial functional dive
