How do you feel about tracking your time? Some of you might welcome it and some might feel it’s an infringement on their freedom and privacy. Stig Nyman will bring some clarity on the topic in this week's episode, Stig is a Ph.D. student at the department for Digitalisation at Copenhagen Business School, he has dedicated his time to study the implications of being managed by an algorithm. His rese
Background: 25-hydroxyvitamin D3 (25(OH)D3) affects immune function, bone health, and reproduction. The precursor of 25(OH)D3, vitamin D3, is synthesized upon ultraviolet (UV) radiation exposure, the levels of which vary. Methods: In a one-year observational study, we used multiple statistical approaches to examine 25(OH)D3 metabolism and UV exposure in 217 healthy men (aged 30–50 years) not using
The radiative properties of clouds depend partially on the cloud droplet number concentration, which is determined by the concentration of cloud condensation nuclei (CCN) when the clouds are formed. In turn, CCN concentrations are determined by the atmospheric particle size distribution and their chemical composition. We use a novel Lagrangian modelling framework to examine the origins and history
Insights into past marine carbon cycling and water mass properties can be obtained by means of geochemical proxies calibrated through controlled laboratory experiments with accurate seawater carbonate system (C-system) manipulations. Here, we explored the use of strontium/calcium ratio (Sr/Ca) of the calcite shells of benthic foraminifera as a potential seawater C-system proxy through a controlled
ABSTRACT:Introduction / Rationale: From the onset of the COVID-19 pandemic, social distancing was recommended for adults 70 years and older (70+) in Sweden. From an outside view, they then became deprived of possibilities to engage in meaningful activities. However, as meaning is highly subjective, we need to listen to older adults’ voices to really know.Objectives: To explore how adults 70+ expe
There is limited theoretically informed research on sustainability in the space tourism market. An extended model of goal-directed behaviour (EMGB) is created and verified with individual and organizational interventions, comparing space tourism experienced and non-experienced travellers. Results revealed that individual intervention has fully significant effects on all MGB constructs, while organ
X-ray and neutron scattering from macroscopically rough surfaces and interfaces is considered and a new method of analysis based on the variation of the shape of the total reflection edge in the reflectivity profile is proposed. It was shown that in the limit that the correlation length and the height of the surface roughness are larger than the wavelength (at least 100 times bigger) of the incomi
A 23 factorial design experiment was conducted to study the influence of pre-heating temperature (HT) for manufacturing sample, bonding temperature (BT) onto rheometer, and trimming state (Trim) of the sample on complex shear modulus (G*) and phase angle (δ) using a dynamic shear rheometer on unmodified bitumen of types 50/70, 70/100, and two 160/220 from various sources. In addition, the black di
The modern rigid alpine ski boot has been associated with an increase in severe knee joint injuries. A new design that allows the rear portion of the upper cuff of the boot (rear spoiler) to open when a posterior directed force is applied to it (similar to when a skier falls back on the ski) is investigated. Motion analysis was combined with kinetic measures to estimate the shear and compressive f
L2 motivation research has a longstanding monolingual bias. Recently, however, the motivational systems of a multilingual’s different languages have been conceptualized as constituting a multilingual motivational system, and it has been suggested that interactions between the ideal Lx self and the ideal Ly self can lead to the emergence of an ideal multilingual self. While the notion of an ideal m
The COVID-19 pandemic has accelerated the digital transformation of Higher Education, necessitating a rapid shift from in-person to remote teaching and learning. This study investigates the experiences of doctoral students in an online Sino-Nordic summer school on aging, implemented during the pandemic. A survey was conducted to collect and analyze data on participants’ experiences and perspective
Aquatic microbial responses to changes in the amount and composition of dissolved organic carbon (DOC) are of fundamental ecological and biogeochemical importance. Parallel factor (PARAFAC) analysis of excitation–emission fluorescence spectra is a common tool to characterize DOC, yet its ability to predict bacterial production (BP), bacterial respiration (BR), and bacterial growth efficiency (BGE)
Context: In the past decades, several ecological engineering (eco-engineering) programs have been conducted in China, leading to a significant increase in regional carbon sink. However, the contribution of different eco-engineering programs to carbon uptake is still not clear, as the location of different programs is difficult to identify, and their impacts are concurrent with climate change. Obje
In this study, we evaluate the performance of modified polysulfone (PSF) ultrafiltration (UF) membranes, which incorporate deep eutectic solvents (DES), in treating stormwater laden with natural organic matter e.g. chemical oxygen demand (COD) and total suspended solids (TSS). We also aim to understand how these organic substances, e.g. COD, TSS, from the water source contribute to the fouling of
Research Question/Issue: This is a study of the relationship between business group ownership and constituent firms' adoption of Anglo-American shareholder value governance in African firms at the undertaking of an initial public offering (IPO). Research Findings/Insights: We find business group ownership to be associated with lower Anglo-American corporate governance adoption by constituent firms
Recent research has revealed that low-energy offset polymer solar cells (PSCs) are capable of a power conversion efficiency of over 19%. However, it is unclear how energy offsets and the charge photogeneration process are correlated. Herein, the effect of energy offsets on charge photogeneration dynamics for Y-series molecules (Y5, Y6, Y10, and BTP-4F-12)-based PSCs with the variations of the lowe
Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. However, in some demanding applications, stainless steel does not provide significant corrosion resist
Low-coordinate surface sites, such as those present on high-index step edges, often exhibit chemical reactivity that markedly differs from more close-packed facets. To understand the site-specific reactivity, insight into the three-dimensional atomic arrangement of step edges is needed. Here, we employ atomic-resolution transmission electron microscopy (TEM) of nanoparticles in combination with sc
