Mega-projects are a growing phenomenon worldwide. More and more projects are started and they grow ever bigger in size. At the same time, there is overwhelming evidence that mega-projects tend to run late, overrun in terms of costs and fail to deliver the expected benefits. Paradoxically, more and more money is invested in projects that fail to deliver on their promises.This dissertation analyses
We present an accurate analysis of phase noise in ring oscillators, where each stage in the ring is a CMOS inverter loaded by a capacitance. Closed-form phase noise expressions are obtained in both 1/f2 and 1/f3 offset frequency regions, displaying an excellent agreement with numerical simulations using either ideal Verilog-A MOS models (allowing theoretical predictions to be tested with exactly t
This entry provides a presentation of different leader-follower perspectives. Traditional leadership research has a psychological orientation and focuses on leaders as persons. Leaders are conceptualized as active communicators and subordinates/followers as more or less passive recipients, which implies a monologic, transmission-oriented view of communication. In recent years, there has been a tur
Introduction: The aim was to create readily available algorithms that estimate the individual risk of β-amyloid (Aβ) positivity. Methods: The algorithms were tested in BioFINDER (n = 391, subjective cognitive decline or mild cognitive impairment) and validated in Alzheimer's Disease Neuroimaging Initiative (n = 661, subjective cognitive decline or mild cognitive impairment). The examined predictor
Precipitation variability over the Bolivian Altiplano is strongly affected by local climate and temporal variation of large-scale atmospheric flow. Precipitation is the main water source for drinking water and agricultural production. For this reason, a better understanding of precipitation variability and its relation with climate phenomena can provide important information for forecasting of dro
This paper presents a design teaching approach that aims to support students to shift their approach when exploring, prototyping and testing user interactions with physical products. This is conducted in a bottom-up, iterative manner to change the perspective from focusing on the opportunities of user-involvement during the form-giving process, rather than prematurely stressing the design outcome.
Creativity is a wildly debated topic among scholars and practitioners, but one that lacks consensus. Many have tried to define, describe and explain creativity, its purpose, effect and use. Is creativity a personality trait you are born with, or can you learn to become creative? As a design teacher with a teaching practice focused on the skills of creativity, this is a relevant question, because i
Purpose: Using service-based logic as its theoretical lens, this study aims to approach residents’ place satisfaction in a novel way. The purpose is to explore residents’ perception of the place in which they live and to shed new light on their place satisfaction. Design/methodology/approach: The paper is based on explorative qualitative focus group research. Data were collected in two typical mun
Code-based cryptography is one of the main techniques enabling cryptographic primitives in a post-quantum scenario. In particular, the MDPC scheme is a basic scheme from which many other schemes have been derived. These schemes rely on iterative decoding in the decryption process and thus have a certain small probability p of having a decryption (decoding) error.In this paper we show a very fundam
OBJECTIVES: To simplify the previously published Nottingham 12-year risk prediction model for knee osteoarthritis (OA) and examine whether it can be used to predict the 40-year risk of knee OA in young men.METHODS: We included 40 118 men aged 18 undergoing military conscription in Sweden 1969-70. Diagnostic OA codes were obtained from the Swedish National Patient Register 1987-2010. The original N
Searches for new heavy resonances decaying into different pairings of W, Z, or Higgs bosons, as well as directly into leptons, are presented using a data sample corresponding to 36.1 fb-1 of pp collisions at s=13 TeV collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. Analyses selecting bosonic decay modes in the qqqq, ννqq, ℓνqq, ℓℓqq, ℓνℓν, ℓℓνν, ℓνℓℓ, ℓℓℓℓ,
“Mixing Metaphor” is a compilation of 12 chapters by prominent researchers, introduced by Raymond Gibbs, one of the main actors in the eld of metaphor studies. It is a highly timely contribution that lls a gap between the pre-theoret- ical notion of ‘mixed metaphors’, largely known to the (English-speaking) pub- lic as something to be avoided as it re ects poor style or even sloppy thinking, and s
An account of a poem inspired by a monument in the gardens of a stately home in Denmark.
BACKGROUND: Childhood cancer survivors have an increased risk of cardiovascular disease (CVD) and diabetes mellitus. Because diabetes is a potentially modifiable risk factor for CVD in the general population, it is important to understand how diabetes affects the risk of CVD among childhood cancer survivors. METHODS: This study examined the risk of CVD among survivors with diabetes and 142,742 pop
Ethyl 2-methyl-1,3-dioxolane-2-acetate (CAS # 6413-10-1) was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that ethyl 2-methyl-1,3-dioxolane-2-acetate is not genotoxic. Data from ethyl 2-methyl-1,3-dioxolane-2-acetate show that there are no safety conce
