This article represents the proceedings of a symposium at the 2000 ISBRA Meeting in Yokohama, Japan. The chairs were Claudia Spies and Hanne Tønnesen. The presentations were (1) Relevance of alcohol misuse in surgical patients, by Hanne Tønnesen; (2) Diagnosis of alcohol abuse and alcohol dependence, by Sven Andreasson; (3) Diagnosis of acute alcohol misuse, by Anders Helander; (4) Preoperative in
To date, very little is known about the demography of European settlers in South Africa, since descriptions have been based on Ross's 1975 calculations of a small sample of 300 observations in the Cape Colony. In this paper we provide a broader and deeper account, using a dataset drawn from the Genealogical Institute of South Africa (2008) that includes information on 401,602 observations of settl
Evidence on long-term multigenerational dynamics is often inadequate as large datasets with multiple generations remain very uncommon. We posit that genealogical records can offer a valuable alternative. Rather than exploring the intergenerational transmission of socioeconomic status, we rely on birth and death dates of eighteenth and nineteenth century settlers in South Africa's Cape Colony to es
In recent years, scholars have shown a growing interest in combining control and flexibility when organizing and managing large construction projects, in contrast with the traditional focus on control. Prior research recognizes that there is a paradoxical tension between control and flexibility, meaning that, while both approaches make sense individually, they appear impossible to combine. Large c
Recent socioeconomic changes have created and intensified paradoxical organizational tensions that companies in numerous industries, including the construction sector, need to address when organizing and managing their activities. The nature of these tensions has not been sufficiently explored in the existing construction management literature. Thus, this study analyzes tensions between control an
Most organizations need to be ambidextrous by exploiting current knowledge to make profits today as well as exploring new knowledge to prepare for tomorrow's demands. The capacity to achieve both exploration and exploitation is especially problematic in project based organizations due to projects' discontinuous nature. In this study we investigate how exploration and exploitation is managed in int
The construction industry is often described as mature, conservative and resistant to change in research studies, governmental reports as well as in media. Both scholars and policy makers thereby find it critical to encourage innovation, development, and change within the construction industry. This study takes on a different perspective by investigating changes that have actually taken place. The
We report the discovery and characterization of a new symbiotic star of the accreting-only variety, which we observed in the optical/near-infrared (NIR) with VLT/X-shooter and in the X-rays/ultraviolet with Swift/UVOT+XRT. The new symbiotic star, THA 15-31, was previously described as a pre-main sequence star belonging to the Lupus 3 association. Our observations, ancillary data, and Gaia EDR3 par
To better understand the genetics of hearing loss, we performed a genome-wide association meta-analysis with 125,749 cases and 469,497 controls across five cohorts. We identified 53/c loci affecting hearing loss risk, including common coding variants in COL9A3 and TMPRSS3. Through exome sequencing of 108,415 cases and 329,581 controls, we observed rare coding associations with 11 Mendelian hearing
We are an international collective of Early Career Academics (ECAs) who met throughout 2020 to explore the implications of COVID-19 on precarious academics. With this intervention, our aims are to voice commonly shared experiences and concerns and to reflect on the extent to which the pandemic offers opportunities to redefine Higher Education and research institutions, in a context of ongoing prec
Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of six years, spectra of ~105 stars. This survey provides not only the reduced spectra, but also the stellar parameters and abundances resulting from the analysis of the spectra. Aims. The GES dataflow is organised in 19 working groups. Working group 13 (WG13) is responsible for the spectral
Context. The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and the central massive black hole, one of the main components in the central parts of our Milky Way. However, until recently, only a few studies of the stellar content of the NSD have been obtained owing to extreme extinction and stellar crowding. Aims. We study the kinematics and global metallicities of the
Impact cratering is today recognized as a fundamental geological process on all rocky bodies in the solar system. On Earth, however, processes such as plate tectonics and erosion have eradicated most craters from the geological record, or they may be buried under sediments, oceans, and vegetation. The formation of a hypervelocity impact crater involves extreme pressures and temperatures that induc
We exploit the 7 Ms Chandra observations in the Chandra Deep Field-South (CDF-S), the deepest X-ray survey to date, coupled with CANDELS/GOODS-S data, to measure the total X-ray emission arising from 2076 galaxies at 3.5 ≤ z < 6.5. This aim is achieved by stacking the Chandra data at the positions of optically selected galaxies, reaching effective exposure times of ≥109s.We detect significant (>3.
The use of biofilms to improve the removal of organic micropollutants in waste¬water treatment plants (WWTPs) has been investigated. The work is divided into two parts. In the first part, the use of biofilms for the biological degradation of micro¬pollutants was investigated. In the second part, micropollutant removal was investigated with biofilm processes in combination with ozonation or activat
