Monitoring of biological markers indicative of doping: the athlete biological passport

The athlete biological passport (ABP) was recently implemented in anti-doping work and is based on the individual and longitudinal monitoring of haematological or urine markers. These may be influenced by illicit procedures performed by some athletes with the intent to improve exercise performance. Hence the ABP is a valuable tool in the fight against doping. Actually, the passport has been defined as an individual and longitudinal observation of markers. These markers need to belong to the biological cascade influenced by the application of forbidden hormones or more generally, affected by biological manipulations which can improve the performance of the athlete. So far, the haematological and steroid profile modules of the ABP have been implemented in major sport organisations, and a further module is under development. The individual and longitudinal monitoring of some blood and urine markers are of interest, because the intraindividual variability is lower than the corresponding interindividual variability. Among the key prerequisites for the implementation of the ABP is its prospect to resist to the legal and scientific challenges. The ABP should be implemented in the most transparent way and with the necessary independence between planning, interpretation and result management of the passport. To ensure this, the Athlete Passport Management Unit (APMU) was developed and the WADA implemented different technical documents associated to the passport. This was carried out to ensure the correct implementation of a profile which can also stand the challenge of any scientific or legal criticism. This goal can be reached only by following strictly important steps in the chain of production of the results and in the management of the interpretation of the passport. Various technical documents have been then associated to the guidelines which correspond to the requirements for passport operation. The ABP has been completed very recently by the steroid profile module. As for the haematological module, individual and longitudinal monitoring have been applied and the interpretation cascade is also managed by a specific APMU in a similar way as applied in the haematological module. Thus, after exclusion of any possible pathology, specific variation from the individual norms will be then considered as a potential misuse of hormones or other modulators to enhance performance.

Integrating sexuality into gynaecological consultations: gynaecologists' perspectives

There are currently few studies exploring doctors' personal perspectives on integrating sexuality into medical consultations. This study focuses on the views of gynaecologists on introducing, or not introducing, sexuality into their work. A total of 30 semistructured interviews were conducted with gynaecologists in the French-speaking part of Switzerland. The thematic content analysis and computer-assisted lexical analysis (Alceste) on the interview transcripts highlighted four categories: perceptions and description of sexuality, patient's sexological history, training in sexology and perceived difficulties. It is observed that, above all, the 'medical dimension' characterises gynaecologists' perceptions. Of greater interest is our observation of disparities in gynaecologists' discussion of their practice, which is often the product of lay knowledge based on common sense and/or personal experience. Finally, the decision to integrate questions relating to sexuality seems to depend on non-medical factors such as the personal experience, interest or gender of the doctor.

Multiple Kernel Learning of Environmental Data. Case study: Analysis and Mapping of Wind Fields

The paper presents the Multiple Kernel Learning (MKL) approach as a modelling and data exploratory tool and applies it to the problem of wind speed mapping. Support Vector Regression (SVR) is used to predict spatial variations of the mean wind speed from terrain features (slopes, terrain curvature, directional derivatives) generated at different spatial scales. Multiple Kernel Learning is applied to learn kernels for individual features and thematic feature subsets, both in the context of feature selection and optimal parameters determination. An empirical study on real-life data confirms the usefulness of MKL as a tool that enhances the interpretability of data-driven models.

La crítica feminista y el problema de la forma

Dice Beatriz Sarlo (2001, p. 28) que un intelectual es aquel que pone en escena los términos de un problema y obliga a una definición colectiva que los tome en cuenta. Para que esto suceda el intelectual debe ser también quien se interroga por las categorías con las que opera. Si la literatura existe como problema, según mi perspectiva, para la crítica feminista, esto se debe a que la operación que vincula el concepto de literatura y el de crítica feminista debe necesariamente definirse en relación con un horizonte hoy en retirada, pero cuya crepuscular energía obliga constantemente a apelar a sus herramientas: la estética.

Development of a New Process for Determining Design Year Traffic Demands, TR-528, 2007

Researchers should continuously ask how to improve the models we rely on to make financial decisions in terms of the planning, design, construction, and maintenance of roadways. This project presents an alternative tool that will supplement local decision making but maintain a full appreciation of the complexity and sophistication of today’s regional model and local traffic impact study methodologies. This alternative method is tailored to the desires of local agencies, which requested a better, faster, and easier way to evaluate land uses and their impact on future traffic demands at the sub-area or project corridor levels. A particular emphasis was placed on scenario planning for currently undeveloped areas. The scenario planning tool was developed using actual land use and roadway information for the communities of Johnston and West Des Moines, Iowa. Both communities used the output from this process to make regular decisions regarding infrastructure investment, design, and land use planning. The City of Johnston case study included forecasting future traffic for the western portion of the city within a 2,600-acre area, which included 42 intersections. The City of West Des Moines case study included forecasting future traffic for the city’s western growth area covering over 30,000 acres and 331 intersections. Both studies included forecasting a.m. and p.m. peak-hour traffic volumes based upon a variety of different land use scenarios. The tool developed took goegraphic information system (GIS)-based parcel and roadway information, converted the data into a graphical spreadsheet tool, allowed the user to conduct trip generation, distribution, and assignment, and then to automatically convert the data into a Synchro roadway network which allows for capacity analysis and visualization. The operational delay outputs were converted back into a GIS thematic format for contrast and further scenario planning. This project has laid the groundwork for improving both planning and civil transportation decision making at the sub-regional, super-project level.

Living with diabetes: quality of care and quality of life

Background: The aim of this research was to characterize the experience of living with diabetes mellitus (DM) and identify patients" opinions of the quality of care received and the results of interventions. Methods: A descriptive, exploratory evaluation study using qualitative methodology was performed. Participants consisted of 40 adult patients diagnosed with DM and followed up in a public hospital in Barcelona, Spain. A semistructured interview and a focus group were used and a thematic content analysis was performed. Results: Patients described DM as a disease that is difficult to control and that provokes lifestyle changes requiring effort and sacrifice. Insulin treatment increased the perception of disease severity. The most frequent and dreaded complication was hypoglycemia. The main problems perceived by patients affecting the quality of care were related to a disease-centered medical approach, lack of information, limited participation in decision-making, and the administrative and bureaucratic problems of the health care system. Conclusion: The bureaucratic circuits of the health care system impair patients" quality of life and perceived quality of care. Health professionals should foster patient participation in decision-making. However, this requires not only training and appropriate attitudes, but also adequate staffing and materials.

Model-based Segmentation and Image Fusion of 3D Computed Tomography and 3D Ultrasound of the Eye for Radiotherapy Planning

For radiotherapy treatment planning of retinoblastoma inchildhood, Computed Tomography (CT) represents thestandard method for tumor volume delineation, despitesome inherent limitations. CT scan is very useful inproviding information on physical density for dosecalculation and morphological volumetric information butpresents a low sensitivity in assessing the tumorviability. On the other hand, 3D ultrasound (US) allows ahigh accurate definition of the tumor volume thanks toits high spatial resolution but it is not currentlyintegrated in the treatment planning but used only fordiagnosis and follow-up. Our ultimate goal is anautomatic segmentation of gross tumor volume (GTV) in the3D US, the segmentation of the organs at risk (OAR) inthe CT and the registration of both. In this paper, wepresent some preliminary results in this direction. Wepresent 3D active contour-based segmentation of the eyeball and the lens in CT images; the presented approachincorporates the prior knowledge of the anatomy by usinga 3D geometrical eye model. The automated segmentationresults are validated by comparing with manualsegmentations. Then, for the fusion of 3D CT and USimages, we present two approaches: (i) landmark-basedtransformation, and (ii) object-based transformation thatmakes use of eye ball contour information on CT and USimages.

Thin Bonded Concrete Overlay with Fast Track Concrete, Final Report, HR-531, 1990

Pavements have been overlaid with thin bonded portland cement concrete (PCC) for several years. These projects have had traffic detoured for a period of 5-10 days. These detours are unacceptable to the traveling public and result in severe criticism. The use of thin bonded fast track overlay was promoted to allow a thin bonded PCC overlay with minimal disruption of local traffic. This project demonstrated the concept of using one lane of the roadway to maintain traffic while the overlay was placed on the other and then with the rapid strength gain of the fast track concrete, the construction and local traffic is maintained on the newly placed, thin bonded overlay. The goals of this project were: 1. Traffic usage immediately after placement and finishing. 2. Reduce traffic disruption on a single lane to less than 5 hours. 3. Reduce traffic disruption on a given section of two-lane roadway to less than 2 days. 4. The procedure must be economically viable and competitive with existing alternatives. 5. Design life for new construction equivalent to or in excess of conventional pavements. 6. A 20 year minimum design life for rehabilitated pavements.

Prólogo: Feminismo y crítica literaria

El feminismo ha sido una de las revoluciones más importantes de este siglo que termina. Ha demostrado que discursos aparentemente neutros y universales como la filosofía, la historia, el psicoanálisis, la religión e incluso la ciencia están en realidad sexuados en masculino. Esta recopilación de artículos (primer volumen de la Serie Mujeres y culturas) quiere reflejar el diálogo entre los estudios feministas y estos campos del saber, combinando una clara vocación divulgativa y pedagógica con el rigor de la investigación académica. Sus autores, especialistas en la materia, ilustran el debate teórico con ejemplos procedentes del cine, la literatura y el arte, acompañados de una amplia bibliografía.Este libro, en definitiva, interesa a todas las personas que quieran reflexionar sobre las relaciones entre los sexos, entre el yo y el otro, y sobre la legitimación teórica de las prácticas políticas destinadas a acabar con las desigualdades reales y simbólicas que perviven en nuestra sociedad.
