Geomagnetic field models constrained by direct observations extend back some 400 years and the magnitude of decadal to centennial variations that they display is often assumed to be typical of the secular variation over longer timescales. Here we present archaeomagnetic directions from layered Neolithic hearths in Orkney, dating to around 3000 BCE, that challenge this assumption. Combining stratig
Working Capital Management (WCM) is a management tool used in large companies to optimize the use of cash by minimizing the amount of cash tied up in working capital accounts, in order to reduce the risk of insolvency and to increase profitability. One of the main reasons why start-ups fail is related to liquidity issues. Despite a wide acceptance regarding the importance of WCM for start-ups, the

Today’s modern societies are becoming increasingly dependent on the vital societal functions that technical critical infrastructures provide, for example availability of electricity, tap water and internet connectivity. Hence, it is of essence that these infrastructures are resilient to interruptions. The purpose of this thesis is to investigate and contrast resilience levels of different types of
Under 2014 så delade Lunds kommun ut 830 gratis cykelhjälmar. Sådana styrande kampanjer är vanliga i Sverige, ändå har ingen kampanj någonsin blivit utvärderad. Syftet med denna uppsats är tvådelad. Först, att utvärdera hur många av de 830 cyklisterna som faktiskt bär hjälmen som de blev tilldelade. Sedan, att nå insikt om varför vissa cyklister väljer att bära hjälmen och varför andra väljer att
United Nations Security Council Resolution 1325 has been hailed as a groundbreaking achievement.

National Action Plans or NAPs have been developed in conjunction with the agenda to legitimise, spread and speed up the implementati
In the past decades, increased organic carbon concentrations have been reported from freshwaters across the Northern Hemisphere. However, there is little knowledge regarding whether or not these changes are linked to increasing concentrations of organic nitrogen. This poor understanding of nitrogen biogeochemistry is a problem in face of the potential eutrophication effects of nitrogen in receivin
