The Empirical Reality of IT Project Cost Overruns: Discovering A Power-Law Distribution Open
If managers assume a normal or near-normal distribution of Information Technology (IT) project cost overruns, as is common, and cost overruns can be shown to follow a power-law distribution, managers may be unwittingly exposing their organ…

The correlation between breath acetone and blood betahydroxybutyrate in individuals with type 1 diabetes Open
Ketone testing is an important element of the self-management of illness in type 1 diabetes. The aim of the present study was to see if a breath test for acetone could be used to predict quantitatively the levels of the ketone betahydroxyb…

Regression to the Tail: Why the Olympics Blow Up Open
The Olympic Games are the largest, highest-profile, and most expensive megaevent hosted by cities and nations. Average sports-related costs of hosting are $12.0 billion. Non-sports-related costs are typically several times that. Every Olym…

Event timing in human vision: Modulating factors and independent functions Open
Essential for successful interaction with the environment is the human capacity to resolve events in time. Typical event timing paradigms are judgements of simultaneity (SJ) and of temporal order (TOJ). It remains unclear whether SJ and TO…

HIV-1 p24Gag adaptation to modern and archaic HLA-allele frequency differences in ethnic groups contributes to viral subtype diversification Open
Pathogen-driven selection and past interbreeding with archaic human lineages have resulted in differences in human leukocyte antigen (HLA)-allele frequencies between modern human populations. Whether or not this variation affects pathogen …

Movement reveals reproductive tactics in male elephants Open
Long‐term bio‐logging has the potential to reveal how movements, and hence life‐history trade‐offs, vary over a lifetime. Reproductive tactics in particular may vary as individuals' trade‐off current investment versus lifetime fitness. Mal…

Effects of Monocular Atropinization on Refractive Error and Eye Growth in Infant New World Monkeys Open
Atropine caused the infant marmoset lens to move forward and thicken, a relative myopia, and increases in the between-animals variance in VCD, which could be considered a failure of emmetropization.

<i>In vitro</i> decidualisation of human endometrial stromal cells is enhanced by seminal fluid extracellular vesicles Open
Extracellular vesicles are highly abundant in seminal fluids and have a known role enhancing sperm function. Clinical pregnancy rates after IVF treatment are improved after female exposure to seminal fluid. Seminal fluid extracellular vesi…

Time‐lapse cameras reveal latitude and season influence breeding phenology durations in penguins Open
Variation in the phenology of avian taxa has long been studied to understand how a species reacts to environmental changes over both space and time. Penguins ( Sphenicidae ) serve as an important example of how biotic and abiotic factors i…

Time-lapse imagery of Adélie penguins reveals differential winter strategies and breeding site occupation Open
Polar seabirds adopt different over-wintering strategies to survive and build condition during the critical winter period. Penguin species either reside at the colony during the winter months or migrate long distances. Tracking studies and…

Does Infrastructure Investment Lead to Economic Growth or Economic Fragility? Evidence from China Open
The prevalent view in the economics literature is that a high level of infrastructure investment is a precursor to economic growth. China is especially held up as a model to emulate. Based on the largest dataset of its kind, this paper pun…

Big is Fragile: An Attempt at Theorizing Scale Open
In this paper we characterise the propensity of big capital investments to systematically deliver poor outcomes as "fragility," a notion suggested by Nassim Taleb. A thing or system that is easily harmed by randomness is fragile. We argue …

Monitoring chicken flock behaviour provides early warning of infection by human pathogen <i>Campylobacter</i> Open
Campylobacter is the commonest bacterial cause of gastrointestinal infection in humans, and chicken meat is the major source of infection throughout the world. Strict and expensive on-farm biosecurity measures have been largely unsuccessfu…

HIV-infected sex workers with beneficial HLA-variants are potential hubs for selection of HIV-1 recombinants that may affect disease progression Open
Cytotoxic T lymphocyte (CTL) responses against the HIV Gag protein are associated with lowering viremia; however, immune control is undermined by viral escape mutations. The rapid viral mutation rate is a key factor, but recombination may …
