Biochar: a win-win-win solution for sustainable small-scale farming in Sweden?

Hur ser framtidens jordbruk ut? Hur ska utmaningar som klimatförändringar och försämrade jordbruksmarker kunna hanteras samtidigt som tillräckliga mängder mat produceras för att föda den ständigt växande mänskliga befolkningen? Genom pyrolys, det vill säga upphettning av biomassa utan tillgång till syre, skapas biokol, ett stabilt material med hög porositet och mycket hög kolhalt. Biokol kan plöjaBiochar is a recalcitrant carbon rich solid product widely praised for the ability to improve soil fertility and sequester carbon, thereby improving crop yields and mitigating climate change. In addition to this, gaseous by products from production can be combusted for energy. Despite the recent global peaks in biochar research, studies focused on temperate regions are relatively scarce and few Eu

Understanding the Complexity of Emerging Markets from a Multinational Company Perspective - A Case Study of the Nigerian Dairy Sector

Reduced growth rates in saturated developed economies have put increasing pressure on multinational companies (MNCs) to expand to rapidly developing emerging markets and capitalize on their value potential.

Investigating the effect of good schools on surrounding housing prices in London

In this paper we have looked at the effect good schools have on surrounding house prices, focusing on London. We consider both the effect of “% of students that meet expected standard in math, reading, and writing”, and the new “progression score” that the UK government has introduced. These two scores are used as the basis of how a school is defined as ‘good’. We used two different propensity sco

Anticipated Events’ Impact on FX Options’ Implied Volatility

Understanding events’ impact on financial instruments are crucial for the participants in the financial markets. Here we propose an approach to model an anticipated event’s impact on the prices of FX options, represented in implied volatility. The model is implemented for anticipated event’s with both Black and Scholes and SABR as the assumed underlying dynamic. The model generates an implied vola

Job Creation in Global Value Chains: An Assessment for the Period of 2000-2014

Globalization has led to the emergence of global value chains (GVCs) and most of the world’s trade is now in intermediate inputs. This has raised questions about employment in GVCs and attracted the interest of researchers and policymakers alike, but is difficult to study empirically. This paper investigates job creation in simple and complex GVCs for 43 economies between 2000 and 2014 on the basi

Födas, åldras, låna

Hushållens skuldsättningsgrad är av intresse för en mängd instanser i samhället eftersom denna bland annat kan ge en bild av hur allvarligt en ekonomisk kris skulle drabba hushållen. Om man kan hitta en modell som väldigt väl förklarar hushållens skuldsättningsnivå kan man eventuellt också upptäcka potentiellt farliga situationer i ekonomin tidigare och då ha möjlighet att sätta in åtgärder mot deHousehold debts is interesting for a number of institutions in society. One reason for this is that it gives a picture of how severely a potential economic crisis might affect the country. If a model can be found which precisely explains the household debt levels, it can be used to predict dangerous situations at an earlier stage, so that resources to counteract the situation can be employed befor
