Hyperspectral and multispectral remote sensing for mapping grassland vegetation

Popular Abstract in English European dry extensive grasslands are biodiversity hotspots which are severely threatened by land use intensification and abandonment. In order to plan efficient conservation actions it is necessary to collect information on the current status of grasslands, their species diversity and prevailing environmental conditions. Remote sensing technology in combination with grAs a consequence of agricultural intensification, large areas of species-rich grasslands have been lost and farmland biodiversity has declined. Previous studies have shown that the continuity of grazing management can have a significant influence on the environmental conditions and the levels of plant species diversity in grassland habitats. The preservation of species-rich grasslands has become a

Engineering Work - On Peer Reviewing as a Method of Horizontal Control

The existing research has produced a useful palette of ideas that help us make sense of the phenomenon of organizational control. But there is a trend that hampers the interpretative possibilities: a heavy bias towards vertical forms of control. It is frequently assumed that the control that operates in organizations has its origin in the actions of managers. This assumption is especially problema

Evaluating the learning effectiveness of using simulations in software project management education: results from a twice replicated experiment

The increasing demand for software project managers in industry requires strategies for the development of management-related knowledge and skills of the current and future software workforce. Although several educational approaches help to develop the necessary skills in a university setting, few empirical studies are currently available to characterise and compare their effects. This paper prese

Optimal stomatal behaviour around the world

Stomatal conductance (g(s)) is a key land-surface attribute as it links transpiration, the dominant component of global land evapotranspiration, and photosynthesis, the driving force of the global carbon cycle. Despite the pivotal role of g(s) in predictions of global water and carbon cycle changes, a global-scale database and an associated globally applicable model of g(s) that allow predictions

Gene-environment interaction and male reproductive function.

As genetic factors can hardly explain the changes taking place during short time spans, environmental and lifestyle-related factors have been suggested as the causes of time-related deterioration of male reproductive function. However, considering the strong heterogeneity of male fecundity between and within populations, genetic variants might be important determinants of the individual susceptibi

Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

Popular Abstract in French La rencontre des sexes est une nécessité pour la majeure partie des organismes appartenant au règne animal. Au cours de l’évolution, différentes modalités sensorielles, comme la vue, l’ouie et l’odorat, sont apparues et ont été perfectionnées pour permettre aux organismes de percevoir l’environnement qui les entourent, et de communiquer. Reconnaître ses pairs de ses enneChemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. Moths (Insecta: Lepidoptera) contributes highly relevant examples to the theory of speciation because subtle

Global environmental governance in the Anthropocene: An introduction

The term Anthropocene denotes a new geological epoch characterized by the unprecedented impact of human activities on the Earth’s ecosystems. While the natural sciences have advanced their understanding of the drivers and processes of global change considerably over the last two decades, the social sciences lag behind in addressing the fundamental challenge of governance and politics in the Anthro

Conclusions: Complexity, Responsibility and Urgency in the Anthropocene

The term Anthropocene denotes a new geological epoch characterized by the unprecedented impact of human activities on the Earth’s ecosystems. While the natural sciences have advanced their understanding of the drivers and processes of global change considerably over the last two decades, the social sciences lag behind in addressing the fundamental challenge of governance and politics in the Anthro

Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries

Popular Abstract in English The concern about pollutant emissions from combustion devices has stimulated the development of modern combustion devices. As one of the major power generation machines, modern gas turbine engine has been designed to run at fuel-lean and premixed mode of combustion in which the combustion temperature is moderate so that NOx emission is low. Combustion in premixed mode rThis thesis deals with the physics of turbulent swirling flows. Large eddy simulation (LES) method is used to investigate the vortex breakdown process, the precessing vortex core (PVC), and the effect of swirl number and flow field configuration on swirling flows. The study is based on an open source CFD code, \textit{OpenFoam}. Turbulent swirling flows are widely used in combustion devices such a

Diffusion of the Balanced Scorecard in the Swedish Municipality Sector

This article examines the introduction of the Balanced Scorecard (BSC) among municipalities in Sweden from a diffusion perspective. The point of departure in the article is that there is a gap in our understanding concerning the diffusion of new management accounting constructs. Over the last decade, research has largely been based on empirical evidence regarding early adopters. Furthermore, these

Jerusalem mitt i byn. Det tidigmedeltida kyrkobyggandet ur rituellt perspektiv.

The stone churches of the early medieval period are commonly supposed to have been built at the instance of society’s upper echelon, the buildingsthemselves being seen as symbolic proclamations of the social hegemony of the class concerned. The present article seeks to broaden the perspective regarding both the prime movers of church building and their motives. The building of a church required th

Film Tourism collaborations: a critical analysis of INTERREG destination development projects

This chapter discusses the different stakeholders that take part in film tourism development projects, how do they collaborate, and what is actually possible to achieve? It is a critical analysis especially when it comes to the selection of stakeholders, the project process and potential outcomes in EU-funded INTERREG projects. The analysis contributes to enhance the knowledge about the different

Coevolution of coloration and colour vision?

The evolutionary relationship between signals and animal senses has broad significance, with potential consequences for speciation, and for the efficacy and honesty of biological communication. Here we outline current understanding of the diversity of colour vision in two contrasting groups: the phylogenetically conservative birds, and the more variable butterflies. Evidence for coevolution of col

Making Direct Democracy Work : An economic perspective on the graphe paranomon in ancient Athens

The specific way the Athenians set up their democracy presents both theoretical and empirical challenges. Decisions were taken by majority vote in the Assembly. To keep politicians in line, the Athenians first used ostracism, which however was replaced by the graphe paranomon around 415 BCE. The latter provided that anybody who had made a proposal in the Assembly could be accused of having made an

Advocacy Coalition Learning – Biases and Heuristics in Policy Implementation

Policy implementation is a complex process and the theoretical problem has been approached in different ways for a long time. Perspectives have converged around governance, negotiation and adaptation and the learning perspective is increasingly acknowledged. This paper explores how policy implementation may be understood from a learning perspective, affected by universal tendencies for humans to d

The dry season intensity as a key driver of NPP trends

We analyze the impacts of changing dry season length and intensity on vegetation productivity and biomass. Our results show a wetness asymmetry in dry ecosystems, with dry seasons becoming drier and wet seasons becoming wetter, likely caused by climate change. The increasingly intense dry seasons were consistently correlated with a decreasing trend in net primary productivity (NPP) and biomass fro

Modeling bumble bee population dynamics with delay differential equations

Bumble bees are ubiquitous creatures and crucial pollinators to a vast assortment of crops worldwide. Bumble bee populations have been decreasing in recent decades, with demise of flower resources and pesticide exposure being two of several suggested pressures causing declines. Many empirical investigations have been performed on bumble bees and their natural history is well documented, but the un

Deciphering systemic lupus erythematosus-associated serum biomarkers reflecting apoptosis and disease activity

Systemic lupus erythematosus (SLE) is a severe chronic inflammatory autoimmune connective tissue disease. Despite major efforts, SLE remains a poorly understood disease with unpredictable course, unknown etiology and complex pathogenesis. Apoptosis combined with deficiency in clearing apoptotic cells is an important etiopathogenic event in SLE, which could contribute to the increased load of poten

Method for evaluation of renovation measures with regards to moisture and emission loads : Based on risk assessments

Renovating the European building stock has for almost two decades been a matter of importance. For Sweden, it is important to renovate its multifamily buildings in order to achieve a reduced energy use, but also because renovation is needed due to building materials and services reaching (or having passed) the end of their life span. In order to renovate properly, renovation measures must be imple
