The first significant buildup in atmospheric oxygen, the Great Oxidation Event (GOE), began in the early Paleoproterozoic in association with global glaciations and continued until the end of the Lomagundi carbon isotope excursion ca. 2,060 Ma. The exact timing of and relationships among these events are debated because of poor age constraints and contradictory stratigraphic correlations. Here, we

Using a standard model in which the individual consumption path is computed solving an optimal control problem, we investigate central claims of Piketty (2014). Rather than r > g (confirmed in the data) r−ρ>g – with ρ being the rate of time preference – matters. If this condition holds and the elasticity of substitution in the production function is larger than one, the capital share converges to

We aimed to conduct a narrative review of the rapid advances in knowledge regarding sun exposure and all-cause mortality. Data support the hypothesis that sun exposure avoidance is a major risk factor for all-cause mortality in adjusted analysis (age, income, education, marital status, smoking, and comorbidity). This was caused by an increased risk of death due to cardiovascular disease (CVD) and

Background: Due to the lack of detailed clinical information, existed evidence regarding a link between psychiatric factors and adverse cancer prognosis was inclusive. Results: We identified 1,340 patients (48.8%) with perioperative psychiatric morbidity. Preoperative psychiatric morbidity was significantly associated with both general and surgical complications within 30 days (RR = 1.3, 95% confi

The chapter looks at language variation and change, and the relation of these processes to language reconstruction and classification. The chapter gives an overview of theories, models, methods, and data, describing how diversity and variation is modelled and measured for reconstruction and classification within traditional, comparative and statistical, evolutionary, or phylogenetic methods. First

Recently the 19th century as a formative period of both states and the state system has received more attention by IR scholars, historical sociologists, and historians. A highly generalized argument that this diverse literature has in common is that the state became more state-like, and the international system denser, and therefore more system-like, in the 19th century. The modern world has its r

The knowledge area of ambulance nurses’ competence represents a relatively new research area that cannot be regarded as having been fully explored and described by existing research. There is uncertainty regarding the required competence for ambulance nurses as well as the professional role of the ambulance nurse in ambulance care. It is also not clear if the ambulance nurse educational programmes

Today, work and consumption are notably blurred. Consumption matters are found to make inroads into the realm of work, while consumption gains traction in the domain of production. This special issue of ephemera gets to the heart of this phenomenon. Covering a range of themes – genetic testing, self-quantification, migration, popular media and modern workplaces – the contributions to this issue ca

Background: Behavioral testing provides an essential approach in further developing our understanding of brain structure and function. The aim of our study was to outline a more expanded approach to cognition- and anxiety-related behavior in the rabbit. Methods: Twenty-one 70-day old rabbits (13 female, 8 male) were exposed to open field test, dark-light box test and object recognition testing wit

Plastics are versatile materials with environmental, technical, economical and societal benefits, however plastics also contribute negatively to the environment and climate. Put in numbers around 4% of the fossil oil and gas is used as feedstock for plastics while another 4% is used for providing energy for the manufacturing of plastics. Many initiatives on reducing the negative effects of plastic

A black box in the study of representation in European democracies is our knowledge about elected but also unelected candidates. What is their background? How are they recruited? What are their campaign aims, strategies, resources and tools? How do they relate to their (constituency and central) party and their voters? How do they consider democratic governance at national and European levels? Thi
