Recent HCI research has shown signifcant interest in investigating digital working instructions for guiding novices to perform manual tasks. While performance enhancement has been a primary focus, it is increasingly recognized that technology's impact extends beyond objective metrics. Trainee motivation and engagement plays a pivotal role in enhancing learning outcomes and efectiveness. This paper investigates the utilization of principles from ...

As awareness has grown internationally of the harms caused by fnancial fraud, there has been a concomitant increase in eforts to prevent and control it. Despite this growing awareness, the literature addressing measures against fnancial fraud has not yet been systematically reviewed or synthesised. On the basis of a scoping literature review, this study provides a structured overview of the literature on prevention and control measures targeting ...

The transport system is in a dilemma. On the one hand, the transport system’s emissions are a main driver of global warming and other severe environmental problems. On the other hand, an efcient transport systems and the mobility (the ability to move) that it provides has been a vital prerequisite of social and economic development. Transport and spatial planners have the task to resolve this transport dilemma and fnd solutions that ensure the ...

Hepatitis A and E virus are the most prominent¨ causes of acute viral hepatitis worldwide (chapter ¨1). Despite the availability of an effective vacc ine for hepatitis A virus (HAV), it is widespread¨ in developing countries and outbreaks still occur¨ regularly in industrialized regions. Although most ¨infections are asymptomatic, or have a mild clini cal course, severe cases of hepatitis A may occur, ¨especially in the elderly. The availability ...

Development of appropriate tourism infrastructure is important for protected areas that allow public access for tourism use. This is meant to avoid or minimize unfavourable impacts on natural resources through guiding tourists for proper use. In this paper, a GIS-based method, the least-cost path (LCP) modelling, is explored for planning tourist tracks in a World Heritage site in Northwest Yunnan (China), where tourism is increasing rapidly ...

Robust relationships among soil, water, atmosphere and plants are needed to reliably forecast the plant species composition. In this paper, we show the need for, and the application of, a process-based relationship between soil moisture conditions and vegetation characteristics. We considered 366 groundwater-pendent sites, where oxygen stress, caused by a surplus of soil moisture, codetermines plant performance. We compared two existing indirect ...

We introduce the problem of learning the parameters of the probabilistic database ProbLog. Given the observed success probabilities of a set of queries, we compute the probabilities attached to facts that have a low approximation error on the training examples as well as on unseen examples. Assuming Gaussian error terms on the observed success probabilities, this naturally leads to a least squares optimization problem. Our approach, called ...

Issue tracking systems store valuable data for testing hypotheses concerning maintenance, building statistical prediction models and (recently) investigating developer affectiveness. For the latter, issue tracking systems can be mined to explore developers emotions, sentiments and politeness -affects for short. However, research on affect detection in software artefacts is still in its early stage due to the lack of manually validated data and ...

The ramp loss is a robust but non-convex loss for classification. Compared with other non-convex losses, a local minimum of the ramp loss can be efiectively found. The efiectiveness of local search comes from the piecewise linearity of the ramp loss. Motivated by the fact that the ℓ1-penalty is piecewise linear as well, the ℓ1-penalty is applied for the ramp loss, resulting in a ramp loss linear programming support vector machine (ramp- LPSVM). ...

Solar filaments often exhibit rotation and deflection during eruptions, which would significantly affect the geoeffectiveness of the corresponding coronal mass ejections (CMEs). Therefore, understanding the mechanisms that lead to such rotation and lateral displacement of filaments is a great concern to space weather forecasting. In this paper, we examine an intriguing filament eruption event observed by the Chinese H{\alpha} Solar Explorer ...
