The aim of the study is to investigate anchoring effects in teachers’ assessment. Anchoring effects occur when a preceding judgement influences a subsequent judgement of the same target or task. Our experiment investigates whether teachers use the anchoring heuristic in student assessments and if its occurrence is moderated by the processing goal and teachers’ expertise. We assume that people use processing strategies according to their actual processing goals. Whereas experts are able to choose an adequate information processing depending on the situation, novices are assumed to be more susceptible to use heuristics, e.g. the anchoring heuristic, independent of their actual processing goal. In our experiment expert teachers and teacher students were asked to assess written tests of a student. They received case material including a neutral description and two tests (German and Math). Participants were either instructed to form a first impression of the student (impression formation goal) or to give an educational recommendation (prognosis goal). After reading the case material, the participants received the anchor: They were told that an experienced teacher had already assessed the tests and marked them with a grade of 2 (high anchor) or 4 (low anchor). Afterwards they had to assess the tests by themselves. Results revealed an interaction effect of expertise, anchor and processing goal. Expert teachers who assessed the student’s performance in the German test with the goal of giving an educational recommendation did not use the anchoring heuristic. Furthermore, results showed only a main effect of the anchor when assessing the math test. The assessments of the math test were assimilated to the given anchor independent of the actual processing goal or the teachers’expertise. [less ▲]

Context: Back in 2001, the MIT announced aspect-oriented programming as a key technology in the next 10 years. Nowadays, 10 years later, AOP is still not widely adopted. Objective: The objective of this work is to understand the current status of AOP practice through the analysis of open-source project which use AspectJ. Method: First we analyze different dimensions of AOP usage in 38 AspectJ projects. We investigate the degree of coupling between aspects and base programs, and the usage of the pointcut description language. A second part of our study focuses on testability as an indicator of maintainability. We also compare testability metrics on Java and AspectJ implementations of the HealthWatcher aspect-oriented benchmark. Results: The first part of the analysis reveals that the number of aspects does not increase with the size of the base program, that most aspects are woven in every places in the base program and that only a small portion of the pointcut language is used. The second part about testability reveals that AspectJ reduces the size of modules, increases their cohesion but also increases global coupling, thus introducing a negative impact on testability. Conclusion: These observations and measures reveal a major trend: AOP is currently used in a very cautious way. This cautious usage could come from a partial failure of AspectJ to deliver all promises of AOP, in particular an increased software maintainability. © 2012 Elsevier B.V. All rights reserved.

The potential of geospatial big data has been drawing attention for a few years. Despite the larger and larger market penetration of portable technologies (nomadic and wearable devices like smartphones and smartwatches), their opportunities for travel behavior analysis are still relatively unexplored. The main objective of our study is to extract the human mobility patterns from GPS traces in order to derive an indicator for enhancing Collaborative Mobility (CM) between individuals. The first step, extracting activity duration and location, is done using state-of-the-art automated recognition tools. Sensors data are used to reconstruct individual’s activity location and duration across time. For constructing the indicator, in a second step, we defined different variables and methods for specific case studies. Smartphone sensor data are being collected from a limited number of individuals and for one week. These data are used to evaluate the proposed indicator. Based on the value of the indicator, we analyzed the potential for identifying CM among groups of users, such as sharing traveling resources (e.g., carpooling, ridesharing, parking sharing) and time (rescheduling and reordering activities).

The problem of evaluating the personality of suspects, which runs alongside that of individualising sentencing, is at the centre of current preoccupations known as « the new social defence’ ». This article is concerned with the use of experts in a particular context, that of cases at the higher criminal courts, where the work of experts is built into a chain of different procedural steps and where the personality of the suspect is considered by several different actors. The exchanges around these questions are not so much concerned with defining dangerousness or treatability, as the moral aspect of the crime. This call for expertise shows that, in this process, those involved are constructing practical definitions of responsibility. [less ▲]

Aims/hypothesis The aim of this multicentre, randomised, controlled crossover study was to determine the efficacy of adding continuous glucose monitoring (CGM) to insulin pump therapy (CSII) in type 1 diabetes. Methods Children and adults (n = 153) on CSII with HbA1c 7.5–9.5% (58.5–80.3 mmol/mol) were randomised to (CGM) a Sensor On or Sensor Off arm for 6 months. After 4 months’ washout, participants crossed over to the other arm for 6 months. Paediatric and adult participants were separately electronically randomised through the case report form according to a predefined randomisation sequence in eight secondary and tertiary centres. The primary outcome was the difference in HbA1c levels between arms after 6 months. Results Seventy-seven participants were randomised to the On/Off sequence and 76 to the Off/On sequence; all were included in the primary analysis. The mean difference in HbA1c was –0.43% (–4.74 mmol/mol) in favour of the Sensor On arm (8.04% [64.34 mmol/mol] vs 8.47% [69.08 mmol/mol]; 95% CI −0.32%, −0.55% [−3.50, −6.01 mmol/mol]; p < 0.001). Following cessation of glucose sensing, HbA1c reverted to baseline levels. Less time was spent with sensor glucose <3.9 mmol/l during the Sensor On arm than in the Sensor Off arm (19 vs 31 min/day; p = 0.009). The mean number of daily boluses increased in the Sensor On arm (6.8 ± 2.5 vs 5.8 ± 1.9, p < 0.0001), together with the frequency of use of the temporary basal rate (0.75 ± 1.11 vs 0.26 ± 0.47, p < 0.0001) and manual insulin suspend (0.91 ± 1.25 vs 0.70 ± 0.75, p < 0.018) functions. Four vs two events of severe hypoglycaemia occurred in the Sensor On and Sensor Off arm, respectively (p = 0.40). Conclusions/interpretation Continuous glucose monitoring was associated with decreased HbA1c levels and time spent in hypoglycaemia in individuals with type 1 diabetes using CSII. More frequent self-adjustments of insulin therapy may have contributed to these effects. [less ▲]

The purpose of this study is to validate a noninvasive rotational knee laxity measuring device called “Rotameter P2” with an approach based on Computed Tomography (CT). This CT-approach using X-rays is hence invasive and can be regarded as a precise reference method that may also be applied to similar devices. An error due to imperfect femur fixation was observed but can be neglected for small torques. The most significant estimation error is due to the unavoidable soft tissues rotation and hence flexibility in the measurement chain. The error increases with the applied torque.The assessment showed that the rotational knee angle measured with the Rotameter is still overestimated because of thigh and femur displacement, soft tissues deformation, and measurement artefacts adding up to a maximum of 285% error at +15Nm for the Internal Rotation of female volunteers. This may be questioned if such noninvasive devices for measuring the Tibia-Femoral Rotation (TFR) can help diagnosing knee pathologies and investigate ligament reconstructive surgery. [less ▲]

Image stitching is the process of combining multiple images to produce a panorama or larger image. In many biomedical studies, including those of cancer and infection, the use of this approach is highly desirable in order to acquire large areas of certain structures or whole sections, while retaining microscopic resolution. In this study, we describe the application of Autostitch, viz. software that is normally used for the generation of panoramas in photography, in the seamless stitching of microscope images. First, we tested this software on image sets manually acquired by normal light microscopy and compared the performance with a manual stitching approach performed with Paint Shop Pro. Secondly, this software was applied to an image stack acquired by an automatic microscope. The stitching results were then compared with that generated by a self-programmed rectangular tiling macro integrated in Image J. Thirdly, this program was applied in the image stitching of images from electron microscopy. Thus, the automatic stitching program described here may find applications in convenient image stitching and virtual microscopy in the biomedical research. [less ▲]
