Defining Information Security

This article proposes a new definition of information security, the ‘Appropriate Access’ definition. Apart from providing the basic criteria for a definition—correct demarcation and meaning concerning the state of security—it also aims at being a definition suitable for any information security perspective. As such, it bridges the conceptual divide between so-called ‘soft issues’ ...

Is Formal Language Proficiency in the Home Language Required to Profit from a Bilingual Teaching Intervention in Mathematics? A Mixed Methods Study on Fostering Multilingual Students’ Conceptual Understanding

To what degree can multilingual students profit from bilingual teaching approaches, even when they lack experience in the academic or technical register in their home languages? This study explores this research question in a mixed methods design for a German/Turkish bilingual intervention aimed at fostering conceptual understanding of fractions (five sessions of 90 min each). The ...

Transition Densities and Traces for Invariant Feller Processes on Compact Symmetric Spaces

We find necessary and sufficient conditions for a finite K–bi–invariant measure on a compact Gelfand pair (G,K) to have a square–integrable density. For convolution semigroups, this is equivalent to having a continuous density in positive time. When (G,K) is a compact Riemannian symmetric pair, we study the induced transition density for G–invariant Feller processes on the ...

Neural machine translation for low-resource languages without parallel corpora

The problem of a total absence of parallel data is present for a large number of language pairs and can severely detriment the quality of machine translation. We describe a language-independent method to enable machine translation between a low-resource language (LRL) and a third language, e.g. English. We deal with cases of LRLs for which there is no readily available parallel ...

Population Ageing and Inflation

Recently a view has emerged in the literature that low inflation may also be influenced, among other variables, by demography. However, there is little empirical evidence for this hypothesis. The motivation of this paper is to assess whether inflation is linked to the population age structure, and especially whether an increased old-age dependency ratio is correlated with a lower ...

Oil spill response capabilities and technologies for ice-covered Arctic marine waters: A review of recent developments and established practices

Renewed political and commercial interest in the resources of the Arctic, the reduction in the extent and thickness of sea ice, and the recent failings that led to the Deepwater Horizon oil spill, have prompted industry and its regulatory agencies, governments, local communities and NGOs to look at all aspects of Arctic oil spill countermeasures with fresh eyes. This paper provides ...

The challenges of marine spatial planning in the Arctic: Results from the ACCESS programme

Marine spatial planning is increasingly used to manage the demands on marine areas, both spatially and temporally, where several different users may compete for resources or space, to ensure that development is as sustainable as possible. Diminishing sea-ice coverage in the Arctic will allow for potential increases in economic exploitation, and failure to plan for cross-sectoral ...

On the Claim of Modulations in 36Cl Beta Decay and Their Association with Solar Rotation

Recently, claims were made by Sturrock et al. (Astropart. Phys. 42, 62, 2013), Sturrock, Fischbach, and Scargle (Solar Phys. 291, 3467, 2016; arXiv , 2017) that beta decay can be induced by interaction of the nucleus with solar neutrinos and that cyclic modulations in decay rates are indicative of the dynamics of the solar interior. Transient modulations in residuals from a purely ...

Early Industrial Roots of Green Chemistry and the history of the BHC Ibuprofen process invention and its Quality connection

Conventional wisdom and many published histories of “Green Chemistry” describe its start as being a result of governmental and/or regulatory actions at the US Environmental Protection Agency (“EPA”) during the early 1990’s. But there were many Real World industrial examples of environmentally friendly commercial processes in the oil and commodity chemicals industries for decades ...

Influence of fracture criteria on dynamic fracture propagation in a discrete chain

The extent to which time-dependent fracture criteria affect the dynamic behavior of fracture in a discrete structure is discussed in this work. The simplest case of a semi-infinite isotropic chain of oscillators has been studied. Two history-dependent criteria are compared to the classical one of threshold elongation for linear bonds. The results show that steady-state regimes can ...

Impact of climate change and seasonal trends on the fate of Arctic oil spills

We investigated the effects of a warmer climate, and seasonal trends, on the fate of oil spilled in the Arctic. Three well blowout scenarios, two shipping accidents and a pipeline rupture were considered. We used ensembles of numerical simulations, using the OSCAR oil spill model, with environmental data for the periods 2009–2012 and 2050–2053 (representing a warmer future) as ...

The feeling of grip: novelty, error dynamics, and the predictive brain

According to the free energy principle biological agents resist a tendency to disorder in their interactions with a dynamically changing environment by keeping themselves in sensory and physiological states that are expected given their embodiment and the niche they inhabit (Friston in Nat Rev Neurosci 11(2):127–138, 2010. doi:10.​1038/​nrn2787). Why would a biological agent that ...

Off to market: but which one? Understanding the participation of small-scale farmers in short food supply chains—a Hungarian case study

The research described in this paper was designed to identify the factors that influence the importance small-scale farmers place on different marketing channels of short food supply chains. The focus concerns two entirely different types of market that are present in the bigger cities in Hungary: ‘conventional’ markets where there are no restrictions on locality but the ...

Prompt 27-gauge sutureless transconjunctival vitrectomy for bleb-associated endophthalmitis

Purpose To summarize the characters of 6 bleb-associated endophthalmitis (BAE) cases and to report the outcomes of prompt 27-gauge sutureless transconjunctival vitrectomy to treat these cases. Methods Retrospective, non-randomized, consecutive case series of patients diagnosed with bleb-associated endophthalmitis who underwent prompt 27-gauge vitrectomy. Results The interval to get ...

Improving the success rate of human corneal endothelial cell cultures from single donor corneas with stabilization medium

Main objective of this study was to improve the success rate of human corneal endothelial cell (hCEC) cultures from single donor corneas. We could show that the use of stabilization medium prior to cell isolation may have a positive effect on the success rate of hCEC cultures from single research-grade donor corneas by allowing growth of otherwise possibly not successful cultures ...

From aggregation to interpretation: how assessors judge complex data in a competency-based portfolio

While portfolios are increasingly used to assess competence, the validity of such portfolio-based assessments has hitherto remained unconfirmed. The purpose of the present research is therefore to further our understanding of how assessors form judgments when interpreting the complex data included in a competency-based portfolio. Eighteen assessors appraised one of three ...

Gravity Waves and Wind-Farm Efficiency in Neutral and Stable Conditions

We use large-eddy simulations (LES) to investigate the impact of stable stratification on gravity-wave excitation and energy extraction in a large wind farm. To this end, the development of an equilibrium conventionally neutral boundary layer into a stable boundary layer over a period of 8 h is considered, using two different cooling rates. We find that turbulence decay has ...
