Applying XP Ideas Formally: The Story Card and Extreme X-Machines
By gathering requirements on story cards extreme programming (XP) makes requirements collection easy. However it is less clear how the story cards are translated into a �finished product. We propose that a formal specification method based on X-Machines can be used to direct this transition. Extreme X-Machines �t in to the XP method well, without large overheads in design and maintenance. We also investigate how such machines adapt to change in the story cards and propose how this could be further enhanced

The accumulated literature on signed language interpreting implies that despite the emerging conceptualization of signed language interpreting as a practice profession applying teleological ethics, interpreters struggle to abandon the perception of strict role constructs governed by deontological ethical decision making. The goal of this study is to gain insight into the ethical decision making process amongst a sample of video relay interpreters using the reflective practice of supervision applying demand control schema.
The findings suggest the existence of both teleological and deontological ethical decision making approaches for the practice of interpreting in the video relay setting. The findings also demonstrated participantsâ lack of agency that impacted the prominent gap between a practice professionalism perspective and technical skill orientation among VRS interpreters. The participantsâ application of teleological ethics suggests an awareness of various controls to achieve effective outcomes and develop strategies to improve practice. The participantsâ lack of agency suggests serious deleterious implications for callers and interpreters. An argument is made for interpreters to become functional leaders in acknowledging the apparent relationship between stress, conditions of VRS employment, and effective service as a beneficial means of guiding improved practice
Fair open access: returning control of scholarly journals to their communities
he problem of how we should transition to open access is now urgent. The current situation is one of exorbitant subscription journals and expensive open-access ones, and to address it requires organised action from academics. The Fair Open Access Alliance, set up to facilitate the conversion of existing subscription journals to open access, is an example of such organisation. Alex Holcombe and Mark C. Wilson outline the groupâs five Fair Open Access Principles and encourage all librarians, researchers, and administrators to work together to secure agreement to cancel subscriptions and to pool funds to pay for open access infrastructure

An Agent-Based Simulation API for Speculative PDES Runtime Environments
Agent-Based Modeling and Simulation (ABMS) is an effective paradigm to model systems exhibiting complex interactions, also with the goal of studying the emergent behavior of these systems. While ABMS has been effectively used in many disciplines, many successful models are still run only sequentially. Relying on simple and easy-to-use languages such as NetLogo limits the possibility to benefit from more effective runtime paradigms, such as speculative Parallel Discrete Event Simulation (PDES). In this paper, we discuss a semantically-rich API allowing to implement Agent-Based Models in a simple and effective way. We also describe the critical points which should be taken into account to implement this API in a speculative PDES environment, to scale up simulations on distributed massively-parallel clusters. We present an experimental assessment showing how our proposal allows to implement complicated interactions with a reduced complexity, while delivering a non-negligible performance increase
The effect of age and demographics on rib shape
Elderly populations have a higher risk of rib fractures and other associated thoracic injuries than younger adults, and the changes in body morphology that occur with age are a potential cause of this increased risk. Rib centroidal path geometry for 20Â 627 ribs was extracted from computed tomography (CT) scans of 1042 live adult subjects, then fitted to a sixâparameter mathematical model that accurately characterizes rib size and shape, and a threeâparameter model of rib orientation within the body. Multivariable regression characterized the independent effect of age, height, weight, and sex on the rib shape and orientation across the adult population, and statistically significant effects were seen from all demographic factors (PÂ <Â 0.0001). This study reports a novel aging effect whereby both the rib endâtoâend separation and rib aspect ratio are seen to increase with age, producing elongated and flatter overall rib shapes in elderly populations, with age alone explaining up to 20% of population variability in the aspect ratio of midâlevel ribs. Age was not strongly associated with overall rib arc length, indicating that age effects were related to shape change rather than overall bone length. The rib shape effect was found to be more strongly and directly associated with age than previously documented ageârelated changes in rib angulation. Other demographic results showed height and sex being most strongly associated with rib size, and weight most strongly associated with rib pumpâhandle angle. Results from the study provide a statistical model for building rib shapes typical of any given demographic by age, height, weight, and sex, and can be used to help build populationâspecific computational models of the thoracic rib cage. Furthermore, results also quantify normal population ranges for rib shape parameters which can be used to improve the assessment and treatment of rib skeletal deformity and disease.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/137729/1/joa12632_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/137729/2/joa12632.pd
Leveraging Semantic Web Service Descriptions for Validation by Automated Functional Testing
Recent years have seen the utilisation of Semantic Web Service descriptions for automating a wide range of service-related activities, with a primary focus on service discovery, composition, execution and mediation. An important area which so far has received less attention is service validation, whereby advertised services are proven to conform to required behavioural specifications. This paper proposes a method for validation of service-oriented systems through automated functional testing. The method leverages ontology-based and rule-based descriptions of service inputs, outputs, preconditions and effects (IOPE) for constructing a stateful EFSM specification. The specification is subsequently utilised for functional testing and validation using the proven Stream X-machine (SXM) testing methodology. Complete functional test sets are generated automatically at an abstract level and are then applied to concrete Web services, using test drivers created from the Web service descriptions. The testing method comes with completeness guarantees and provides a strong method for validating the behaviour of Web services
