Investment consultants market their services by claiming their fund manager recommendations add significant value. Using nonpublic data sourced from investment consultants and the UK regulator, we find no such evidence, but identify several practices that explain their exaggerated claims: comparisons to benchmarks instead of peers, inclusion of simulated and backfilled returns, use of investment horizons that allow losers to be forgotten, and unexplained exclusions of products from the analysis. Consultants do not fully disclose their methodology to investors, who therefore cannot verify or reliably compare their performance. This paper was accepted by Haoxiang Zhu, finance.

PurposeVirtual reality (VR) offers unique features of a three-dimensional (3D) model during early design stages in the virtual environment with immersive functions. Although the potential of VR is to increase the effectiveness and productivity of the project phases from initial concept design to detailed design preparation. VR adoption in the United Kingdom (UK) Architectural Engineering and Construction (AEC) sector is slow compared to other sectors. This research focuses on ascertaining the drivers and barriers of VR in construction projects in the UK.Design/methodology/approachThe study adopts an online survey design. It uses Bristol Online Survey (BOS) to create a structured questionnaire that is used to assess UK construction professionals using a convenience sampling technique. Therefore, researcher uses descriptive and inferential technique for data analysis and presentation based on Statistical Package for Social Sciences (SPSS) to analyze the questionnaire.FindingsThe research findings revealed the most significant barriers to VR adoption in UK construction industry were lack of skills/expertise and cultural change. Hence, the main drivers of VR adoption as rated by the professionals in the UK construction industry are improved safety, improved quality and improved productivity.Practical implicationsThe identification and assessment of the drivers and barriers to VR adoption could advance VR adoption among construction professionals and other stakeholders of the UK AEC sector. This could also be extended to developing countries, given the status of VR as being in the developing stage.Originality/valueThis study provides valuable insights to construction professionals and stakeholders to plan actions that could enhance the drivers and mitigate the barriers of VR. This study's main contribution is to group and classify various drivers and barriers into easily understood categories, in order to potentiate the drivers and reduce the barriers effectively. The groupings could be used as benchmarks in similar studies in developing countries.

BackgroundSimulation training in surgery is widespread and allows surgeons to practise novel operative techniques and acquaint themselves with unfamiliar surgical procedures. The use of box or virtual reality simulators in many surgical specialities is established; however, its use within trauma and orthopaedics (T&O) in the UK and the attitudes of trainee towards it are not known. The aim of this study is to explore the experiences and opinions of T&O trainees towards simulation training.MethodsAn electronic survey consisting of 11 questions on the experiences of simulation training and attitudes towards it was sent to all T&O speciality trainees in London.ResultsFewer than 10% of the responders had used or had ready access to simulators to prepare for unfamiliar operations, with almost 90% preferring to read about them in a journal or watch them on an online video site. Over half had only seen simulators on courses or been aware of them. Over 75% of the responders believed that simulators should be available for trainees, but most did not feel that they should be used as part of formal assessments.ConclusionsMethods for preparing for new operations have expanded over the past 20 years, yet the use of simulator machines is not widespread. Many trainees believe current machines are not widely available nor realistic enough to be useful, with most preferring online videos and operative technique books for preparing for an unfamiliar operation.

<p><strong>Abstract.</strong> Virtual reality (VR) is a display and control technology that provides an interactive computer-generated three-dimensional environment to a user, often via a Head Mounted Display (HMD). VR delivers an immediate and immersive sensory experience of simulated worlds (which may or may not resemble reality), particularly of environments that might otherwise be physically inaccessible to the user due to their location, scale, time or danger. Although the first VR systems began to emerge in the 1960s, their relevance to cartographic applications has only recently become an explicit focus of research. Moreover, the potential of VR technology to visualize topographic databases has yet to be explored by cartographers.</p><p>In this experiment, we designed a VR application of a fictitious city derived from state 1&amp;thinsp;:&amp;thinsp;10,000 topographic data (Polish Database of Topographic Objects BDOT10k) to test user preferences for 2D or 3D urban geovisualizations. The app allows the user to switch between 2D and 3D representations of buildings in the simulation using a remote controller. This functionality enabled participants of the experiment to freely select 2D or 3D mode and for their preferences to be recorded and measured.</p><p>Our experiment involved two groups, one based in Poland and one in the UK, each comprising 30 participants (students enrolled on a Geography undergraduate course at each author’s institution). Participants performed spatial ability tests to help ensure consistency in the sample and each group was divided into two sub-groups. Participants in the first sub-group were each given a navigation task that required their movement across the simulated city from point A to point B in the shortest possible time. Those in the second sub-group were given the freedom to explore the simulated city without being given a specific navigational task. We then interviewed participants in order to understand their own perception of their experiences in using the app.</p><p>The results indicate the preferences of the two groups and sub-groups of participants. In particular, we establish whether users preferred the 2D mode for the navigational task and the 3D mode for free exploration. The findings suggest how producers of topographic datasets might develop the functionality of their products using VR.</p>

What causes paranoia? That’s a tough question to answer, and for at least a couple of reasons. For one thing, there’s no simple explanation. Paranoia, like so many psychological experiences, is the result of a complex interaction of numerous factors—as we’ll see over the course of the next three chapters. But there’s a bigger, more fundamental problem. How can we accurately and scientifically observe paranoid thinking? Paranoid thoughts don’t pop into our heads out of the blue. They’re generally our attempt to make sense of something we’ve experienced—perhaps a colleague ignored us at lunch or someone looked at us oddly on the bus. We can ask people about their paranoid thoughts, but how do we get at the truth of the situation? How do we even know for sure whether their thoughts are genuinely paranoid? Perhaps the colleague ignored us because our existing paranoia makes us reluctant to socialize. Or perhaps our fears are a legitimate response to a threatening situation. Maybe the guy on the bus really was looking for trouble. Any rigorous, scientific study of paranoia would need to expose a statistically significant number of people to exactly the same experience to see which of them reacted in a paranoid way. Once you had these data, you could start probing to see whether there was anything distinctive about the paranoid group. But how on earth can we arrange for hundreds of people to experience exactly the same everyday event in laboratory conditions? It’s impossible, right? Actually, there is a way, and it’s one we used in a groundbreaking recent experiment. That way is virtual reality. In the summer of 2006, we sent a leaflet to all households local to King’s College London. The leaflet announced a study of virtual reality at the college and invited people to participate. In the end we recruited 100 men and 100women of varying ages from 18 to 77, and from very diverse socioeconomic backgrounds. The mix, in fact, was pretty representative of the UK as a whole. We didn’t tell the volunteers that we were researching into paranoia until we’d completed the experiment.
