This article investigates the usability of a navigation support tool, which guides learners by generating advice on the next best step to take in a self-study e-learning course. The article draws on log data and responses from online questionnaires to provide insights into learners’ evaluation of the tool, their adherence to the advice and their expectations of self-efficacy. The theoretical un...

I have looked through your archives but have not found an answer to my question. I was diagnosed and treated for chlamydia about a month and a half ago. Do I need to get rid of any sex toys I have? Is it possible to become reinfected by using a sex toy that you used while you were infected if you wash it before using it? Please help me find the answer to my question. I really need to know ASAP!...

This is a review article about knots and links of braid index 3. Its goal is to gather together, in one place, some of the tools that are special to knots and links of braid index 3, in a form that could be useful for those who have a need to calculate, and need to know precisely all the exceptional cases. Knots and links which are closed 3-braids are a very special class. Like 2-bridge knots a...

The constructive definition usually begins with a function f, then by the process of using Riemann sums and limits, we arrive the definition of the integral of f, ∫ b a f. On the other hand, a descriptive definition starts with a primitive F satisfying certain condition(s) such as F ′ = f and F is absolutely continuous if f is Lebesgue integrable, and F is generalized absolutely continuous if f...

In designing MPA networks, planners must decide how they will choose which sites to include. There are a variety of ways to select sites, from simple ones (having experts make a list based on their best judgment) to complex (using advanced software to consider an array of ecological and socioeconomic factors). There are also questions on how best to classify the area you seek to protect. After ...

The aim of the following report is to outline the content of the lectures given during the First IAOA Interdisciplinary Summer School on Ontological Analysis (July 16–20, 2012, Trento, Italy). The report emphasizes some of the hot topics or open questions discussed during the sessions, while reflecting a variety of perspectives on the goals of ontological analysis and the importance of interdis...

2014 Through the description of three new series of polar compounds with a cyano or a nitro terminal group we progress in the generalization of the (x, T) binary diagrams dealing with bilayered fluid smectic phases. New arguments are put forward concerning the conspicuousness of the SAd-S A2 transition according to the structure of the SAd phase. For the second time a SA2~ SC2~ S? bilayer seque...

Once a dialogue strategy has been learned for a particular set of conditions, we need to know how well it will perform when deployed in different conditions to those it was specifically trained for, i.e. how robust it is in transfer to different conditions. We first present novel learning results for different ASR noise models combined with different user simulations. We then show that policies...

Decision making typically requires judgements about causal relations: we need to know both the causal e¤ects of our actions and the causal relevance of various environmental factors. Judgements about the nature and strength of causal relations often di¤er, even among experts. How to handle such diversity is the topic of this paper. First we consider the possibility of aggregating causal judgeme...
