The out of Africa hypothesis (OOAH) has been a mainstay in the discussion of human evolution since its presentation in the 1980's. However, recent advances in palaeontology and molecular genetics have made it possible to examine the hypothesis in a manner that was inconceivable at the time of its proposal. The palaeontological progress relates to early Homo finds in the Caucasus, Denisova finds in

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
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
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
Background: The recently launched high-throughput assays for detecting antibodies against SARS-CoV-2 has contributed to the managing strategies for the COVID-19 pandemic. This study aimed to investigate the performance of three high-throughput assays and one rapid lateral flow test relative to regulatory authorities' recommended criteria. Methods: A total of 315 samples, including 150 pre-pandemic
Increasing drought frequency and intensity affect biophysical functions of natural ecosystems. In tropical semi-arid savannas, while immediate drought effects are well-studied, the drought legacy effects on vegetation composition and associated ecosystem functions remain unclear. We used data of vegetation composition, net ecosystem CO 2 exchange, surface albedo and evapotranspiration (ET) in 201
Wastewater monitoring is highly efficient in SARS-CoV-2 surveillance for tracking virus spread through travel, surpassing traditional airport passenger testing. This study explored the links between SARS-CoV-2 contents and variants from aircraft to city, assessing the impact of detected variants from international travellers versus the local population. A total of 969 variants using next-generatio
The Carnian Pluvial Episode (CPE) was an interval of prominent hydroclimatic perturbations during the early Late Triassic. The causes of these changes have been widely attributed to intensified greenhouse forcing. However, the temporal dynamics of the hydrological cycle across low-latitude regions during the CPE remain poorly constrained. In this study, we present high-resolution organic geochemic
Hybrid energy systems have become a promising strategy for enhancing power utilization efficiency while preserving ecology. Previous research has predominantly focused on developing models with fixed ecological constraints. However, the fixed ecological constraints overlook dynamic ecological uncertainty and its interaction with operation decisions. This study proposes adaptive operating rules for
The development of geospatial big data makes it possible to study traffic-congestion issues. In particular, floating car data (FCD) is very suitable for it because FCD can help predict traffic-congestion bottlenecks and provide corresponding solutions to address traffic problems. Previous studies have discussed the impacts of rainfall on road speeds, but few studies have focused on the impacts of
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
