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).

Dans “Réponse à la question: Qu’est-ce que les Lumières?”, Kant se donne pour tâche de garantir “la plus inoffensive de toutes les libertés, celle de faire publiquement usage de sa raison en toutes choses” et, par là même, de fonder le progrès des lumières dans un discours public de type normalisé. La démarche de Kant se révèle normalisante dans la mesure où elle “rend commensurable toute contribution au discours dans un domaine” (Jeffrey Stout, Ethics After Babel, p. 294, ma traduction): dans l’usage public, tout interlocuteur part d’un vocabulaire épuré, “à titre de savant”, pour s’adresser à un public de “lecteurs” de sorte que tout autre interlocuteur peut accepter les raisons du premier, peu importe sa fonction dans la société. Une telle normalisation des conditions de pratiques discursives peut-elle réellement faire progresser la société humaine comme le prétend Kant? Certes, un discours normalisé rend compte de la fragmentation de l’autorité dans la société moderne. Mais il résiste à l’effort de certains interlocuteurs, peu satisfaits de ses prétentions libérales fondationnalistes, d’y apporter des éléments justificatifs issus non pas des usages publics de la raison mais de ceux dits “privés”. Car, pour Jeffrey Stout, la discussion qui fait réellement progresser la société cosmopolite passe par l’écoute, “l’interaction conversationnelle” et la critique improvisée dans un “discours anormal” (idem.). À force de vouloir fixer les critères du débat en avance, on le rendrait en même temps stérile. Si cela constitue une critique forte d’un discours normalisé kantien dont les principes sont fondationnalistes, il n’exclut nullement un discours normalisé kantien de type non-fondationnaliste. A cet effet, il suffirait de supposer une raison pratique et un discours modaux, sensibles aux particularités des interlocuteurs, selon lesquels l’usage public exige des interlocuteurs des raisons qui pourraient être adoptées de façon cohérente par tout interlocuteur dans le domaine en question (cf. Towards justice and virtue, Onora O’Neill). Dans cet optique modal, l’usage public résiste-il mieux ou finit-il par se rapprocher de ses critiques plus qu’on ne le soupçonne? [less ▲]

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 ▲]

Today, the interest in integrated dynamic analysis of mechatronic systems increases. Different approaches are possible depending on the nature of the system, on the required complexity of the model, or simply on the tools available to the engineer. During this work, the aim was to implement specialized commercial simulation software packages and to combine them in order to simulate the dynamic behavior of mechatronic systems as for example an injection molding machine. The multi-body simulation software is the backbone of the current analysis as it inherently models large non-linear motions. It is possible to account for the flexibility of components in the MBS model if necessary. Furthermore, other simulation codes were used to model the hydraulic and controls systems. The case studies show the interest and the potential of a combined analysis of mechatronic systems. Once the different sub-models, generated with the adequate simulation tool, have been successfully linked and validated by measurements, various scenarios can be simulated and analyzed. The model provides the engineer with an additional insight into the overall system and thus with a better understanding of its dynamic characteristics. The interactions between the subsystems, which may be of very distinctive nature, can be investigated. Generally, it is difficult to predict such relations intuitively. Finally, the model allows to simulate with different design parameters and to asses the effect of modifications to these on the overall performance of the machine. This helps to identify the significant parameters that are crucial for an optimized functioning. [less ▲]

We describe how GPS measurements of horizontal crustal motion can be used to augment vertical crustal motion measurements, to improve and extend GPS studies of surface loading. We show that the ratio of the vertical displacement to the horizontal displacement, combined with the direction of the horizontal motion, can help determine whether nearby loading is concentrated in a small region (for example, in a single lake or glacier), and where that region is. We illustrate this method by applying it to two specific cases: an analysis of GPS data from northern California to monitor the level of Lake Shasta, and the analysis of data from a single GPS site in southeast Greenland to determine mass variability of two large, nearby outlet glaciers: Helheim Glacier and Midgaard Glacier. The California example serves largely as a proof-of-concept, where the results can be assessed by comparing with independent observations (Lake Shasta tide gauge data, in this case). Our Greenland results show that both Helheim and Midgaard have experienced notable interannual variations in mass loss rate over the last decade. Helheim’s mass loss accelerated rapidly in mid-2003, decelerated in late 2005, and increased again in 2008–2009 before returning to about its pre-2003 rate in late 2010. Midgaard’s mass loss accelerated in mid-2004, and remained more-or-less constant before returning to its pre-2003 rate in late 2008. [less ▲]

Current humor research tends to accentuate the positive and neglect the negative. Often, the healing power is in the center of humor research; however, less is reported about the negative effects humor can have if not used adequately. In particular, less is known about the appropriate and in-appropriate use of humor in an intercultural context. The purpose of this bachelor thesis was to bridge this lack in humor research by trying to identify the fine line between appropriate and in-appropriate humor. If humor is used appropriately, it can have a huge power to bridge cultural divides. Thus, this thesis aimed as well to investigate the use of humor as a coping strategy in intimate intercultural couples. Thirdly, additional functions of humor shall be explored. Semi-structured, focused interviews were conducted with two intimate intercultural couples. Participants were of Irish, Luxembourgish, German and French-Canadian nationality. Interview data was then analyzed using qualitative content analysis. Results revealed that the appropriate use of humor depends on personal, linguistic, and cultural factors. Overall, self-deprecating humor seems to be the safest type of humor, whereas sarcasm can be experienced as hurtful even if not intended to be. Ethnic humor can have positive effects, too, if it is directed versus the own culture and not versus foreign cultures. Moreover, results revealed that humor mainly serves two functions in intimate intercultural relationships: the one of bonding and the one of coping. Humor as a coping strategy can be used internally, hence related to relationship issues, as well as externally, thus related to external stressors. One can conclude that the function of bonding and coping cannot be clearly distinguished. Consequently, it proves that humor can be a useful tool in bridging intercultural and interpersonal divides. Limitations of the study clearly lie in its sample size, which does not allow to draw any generalizations. In the future, similar studies with a larger sample size as well as with non-Western cultures would be interesting to investigate in the future. [less ▲]
