To keep global warming within 1.5 °C of pre-industrial levels, there needs to be a substantial decline in the use of coal power by 20301,2 and in most scenarios, complete cessation by 2050. The members of the Powering Past Coal Alliance (PPCA), launched in 2017 at the UNFCCC Conference of the Parties, are committed to “phasing out existing unabated coal power generation and a moratorium on new coa
Solar variability has been hypothesized to be a major driver of North Atlantic millennial-scale climate variations through the Holocene along with orbitally induced insolation change. However, another important climate driver, volcanic forcing has generally been underestimated prior to the past 2,500 years partly owing to the lack of proper proxy temperature records. Here, we reconstruct seasonall
Given the role of social media in the modern election, scholars should not only study how platforms function for political actors; we should also study how platforms function as political actors. This essay therefore introduces the concept of scandalous design, which refers to programmatic changes in how social media operate in response to scandal. On the one hand, scandals can encourage changes i
Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services. Yet how global vegetation is responding to the changing environment is not well established. Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key
Coxsackievirus A24 variant (CVA24v) is a major causative agent of acute hemorrhagic conjunctivitis outbreaks worldwide, yet the evolutionary and transmission dynamics of the virus remain unclear. To address this, we analyzed and compared the 3C and partial VP1 gene regions of CVA24v isolates obtained from five outbreaks in Cuba between 1986 and 2009 and strains isolated worldwide. Here we show tha
Wind energy is a rapidly growing field of renewable energy, and as such, intensive scientific and societal interest has been already attracted. Research on wind turbine structures has been mostly focused on the structural analysis, design and/or assessment of wind turbines mainly against normal (environmental) exposures while, so far, only marginal attention has been spent on considering extreme n
Iridium(iii) half-sandwich complexes containing 7-chloroquinoline-1,2,3-triazole hybrid ligands were synthesised and their inhibitory activities evaluated against the Plasmodium falciparum malaria parasite. Supporting computational analysis revealed that metal coordination to the quinoline nitrogen occurs first, forming a kinetic product that, upon heating over time, forms a more stable cyclometal
ABSTRACT: The microbiological composition of tobacco products was studied using culture and chemical analysis (of tobacco leaves) or chemical analysis only (tobacco and tobacco smoke). The chemical analyses utilized gas chromatography-tandem mass spectrometry for determining 3-hydroxy fatty acids, muramic acid, and ergosterol as markers of respectively lipopolysaccharide (LPS), peptidoglycan, and
Using a new concept—the law of the limit to land productivity—this article builds a three (physical, economic, and institutional) worlds’ land-use model with inverse logics of different development stages in a time perspective: before, in, and after the population trap. This model extends the span of the Malthusian population model to history after the Industrial Revolution and makes static proper
Since 2009, the United Nations Framework Convention on Climate Change (UNFCCC) regime has seen the emergence of several new political groups. This article analyses how the new political groups are positioning themselves in relation to the key UNFCCC principles (the North–South divide and ‘common but differentiated responsibility and respective capabilities’, CBDR/ RC). Drawing on original data, in
The prediction of the influent load is of great importance for the improvement of the control system to a large wastewater treatment plant. A systematic data analysis method is presented in this paper in order to estimate and predict the periodicity of the influent flow rate and ammonia (NH3) concentrations: 1) data filtering using wavelet decomposition and reconstruction; 2) typical cycle identif
Uppsatsen avser att undersöka den gränsdragningsproblematik som kan uppstå när avtalsparter lämnar en klausul öppen för att den vid ett senare tillfälle ska fyllas med innehåll av en tredjeman. Skillnaden mellan dessa värderingsklausuler och skiljeklausuler samt metoder för att undvika problematik med gränsdragningen är centrala frågor. Värderingsklausuler behandlas endast i samband med företagsövThis thesis intends to distinguish the demarcation problems that may arise when two parties leave an open clause, in a contract, to later be filled with content by a third party. The difference between expert valuation clauses and arbitration clauses, and how to avoid problems with demarcation are the key issues of the thesis. Expert valuation clauses will only be considered in the area of mergers
This study focuses on establishing the existence of volatility spillover effects between stock indices that represent developed and emerging markets. We employ a CGARCH(1,1) model, which distinguishes between the short-term (transitory) and long-term (permanent) conditional variance, allowing us to simultaneously examine the time trends of changes in volatility and spillover effects between develo
Based on an explorative case study approach, this thesis investigated whether the Uppsala model functioned in Samsung Electronics Corp. (SEC) case. The purpose of this study was to upgrade the Uppsala model by using a representative case of SEC. This thesis found that there are two dimensions derived from the Uppsala model. The first dimension is the sequential nature of the internationalization p
It is not unusual that women and children fall behind in development countries. It is not even unusual that these groups are exposed to all forms of discrimination due to the countries lack of capacity to erase poverty. We also know that women and children in a larger extent suffers from the shortage of proper health conditions. India is one of these countries. It is a country where women even bef
The aim of this thesis is to discuss the construction of Taiwanese identity in Shanghai and compare with the studies on identity formation in Taiwan itself. The thesis is divided into three parts: cultural identity, ethnic identity and political identity. A total of 10 male and female students from Taiwan who had resided a year and above and enrolled in higher education in Shanghai were interviewe
