Mechanical complications after central venous catheterisation in the ultrasound-guided era : a prospective multicentre cohort study

BACKGROUND: Limited data are available on the incidence of mechanical complications after ultrasound-guided central venous catheterisation. We aimed to determine the incidence of mechanical complications in hospitals where real-time ultrasound guidance is clinical practice for central venous access and to identify variables associated with mechanical complications.METHODS: All central venous cathe

Modelling water and energy fluxes with an explicit representation of irrigation under mulch in a maize field

Globally, water-saving irrigation plays a vital role in agricultural ecosystems to achieve sustainable food production under climate change. Irrigation under mulch (IUM) system has been widely used in modern agricultural ecosystems due to its high water use efficiency, but it remains unclear how each component of the water and energy processes responds to this agricultural management practice. Cur

Perioperative morbidity and mortality in chronic alcoholic patients

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

New estimates of settler life span and other demographic trends in South Africa, 1652-1948

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

The transmission of longevity across generations: The case of the settler Cape Colony

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

Reinforcing cycles involving inter- and intraorganizational paradoxical tensions when managing large construction projects

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

Paradoxical Organizational Tensions between Control and Flexibility When Managing Large Infrastructure Projects

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

Organizational ambidexterity in construction projects

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

Societal changes and new conditions for the management of large construction projects

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

THA 15-31 : Discovery with VLT/X-shooter and Swift /UVOT of a new symbiotic star of the accreting-only variety

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

Population-scale analysis of common and rare genetic variation associated with hearing loss in adults

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

Redefining the role of urban studies Early Career Academics in the post-COVID-19 university

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

The Gaia -ESO Survey : The analysis of the hot-star spectra

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
