Inleiding: Sekse speelt een rol bij medische zorg. In toenemende mate wordt van huisartsen verwacht dat zij rekening houden met contextuele factoren waaronder sekse. In het raamplan van de huisartsopleidingen zijn seksespecifieke competenties beschreven. Om huisartsen in opleiding deze competenties te laten verwerven is onderwijs in seksespecifieke huisartsgeneeskunde noodzakelijk. Methoden: Er is een curriculum ontwikkeld, bestaande uit vijf modules, waarin de seksespecifieke competenties zijn uitgewerkt. Er worden evidence-based leermethoden gebruikt om aios huisartsgeneeskunde seksespecifiek medisch handelen te leren (interactief, praktijkgericht, reflectief). Het seksespecifieke curriculum is een geintegreerd onderdeel van de huisartsopleiding. Tussen 2005–2008 is na elke module de aios gevraagd een evaluatieformulier in te vullen met de bedoeling het onderwijs te evalueren en leerpunten te inventariseren. Resultaten: De modules van het betreffende onderwijsprogramma zijn verdeeld over de driejarige huisartsopleiding. In het onderwijs worden seksespecifieke onderwerpen behandeld met een hoge huisartsgeneeskundige relevantie zoals de arts-patient communicatie, hart- en vaatziekten en depressie. De evaluatie van het onderwijs is overwegend positief. De geformuleerde leerpunten van de aios sluiten aan bij de competenties van het seksespecifieke onderwijsprogramma. Discussie en conclusie: Met succes is een seksespecifiek onderwijsprogramma geimplementeerd in de Nijmeegse huisartsopleiding. De evaluatie laat zien dat het onderwijs in seksespecifieke huisartsgeneeskunde positief wordt gewaardeerd. Daarnaast draagt het onderwijs bij aan een besef van de invloed van de factor sekse in de dagelijkse medische praktijk. De modulaire opbouw en de competentiegerichte onderwijsmethoden maken het geschikt voor andere huisartsopleidingen. (Dielissen PW, Bottema BJAM, Verdonk P, Lagro-Janssen ALM.

Inleiding: Aan het derde jaar van de huisartsopleiding is de keuzemodule ‘Differentiatie’ toegevoegd. Met deze curriculumvernieuwing wordt beoogd de huisarts-in-opleiding (aios) maatwerk te bieden tijdens de opleiding en een aanzet te geven voor een persoonlijke ontwikkeling in de latere beroepspraktijk. Voor deze module stelt de aios bij een zelfgekozen differentiatie- onderwerp een plan op met doelen, activiteiten en tijdsbesteding. In een evaluatiestudie zijn de meningen van aios, huisarts-opleiders (hao’s) en docenten over de praktische uitvoering onderzocht.

Various models for calculating the effective or area-averaged roughness length zoe have been tested for a partly forested area. Three types of model are considered: the tile approach for very large scales of inhomogeneity (> 20 km), drag models for very small scales (up to 1 km), and surface-layer methods such as the blending-height method for intermediate scales. Over partly forested areas, where both pressure effects and roughness sub-layer effects may become significant, small-scale models are expected be the most suitable type of model. The various model types were tested against new experimental data that were obtained over the partly forested Sherwood Forest area (UK). The best fit with the data was obtained with the blending-height method, rather than with the different small-scale models. This is remarkable as the surface-layer assumptions of the blending-height method were clearly violated: the calculated blending height was 7 m, as compared to the mean tree height of 20 m. Of the small-scale models, a sparse-canopy approach compared poorly with the experimental data. The drag models overestimated the area-averaged roughness to a lesser degree, but a major point of concern remains the choice of the model parameters. Therefore, suggestions are made for an improved choice of these parameters.

The Space Telescope Imaging Spectrograph (STIS) instrument was installed on the Hubble Space Telescope (HST) during the second servicing mission, in 1997 February. Four bands cover the wavelength range of 115–1000 nm, with spectral resolving powers between 26 and 200,000. Camera modes are used for target acquisition and deep imaging. Correction for HST's spherical aberration and astigmatism is included. The 115–170 nm range is covered by a CsI MAMA (Multianode Microchannel Array) detector and the 165–310 nm range by a Cs2Te MAMA, each with a format of \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{bm} \usepackage{mathrsfs} \usepackage{pifont} \usepackage{stmaryrd} \usepackage{textcomp} \usepackage{portland,xspace} \usepackage{amsmath,amsxtra} \usepackage[OT2,OT1]{fontenc} \newcommand\cyr{ \renewcommand\rmdefault{wncyr} \renewcommand\sfdefault{wncyss} \renewcommand\encodingdefault{OT2} \normalfont \selectfont} \DeclareTextFontCommand{\textcyr}{\cy...

The Space Telescope Imaging Spectrograph (STIS) was successfully installed into the Hubble Space Telescope (HST) in 1997 February, during the second HST servicing mission, STS-82. STIS is a versatile spectrograph, covering the 115-1000 nm wavelength range in a variety of spectroscopic and imaging modes that take advantage of the angular resolution, unobstructed wavelength coverage, and dark sky offered by the HST. In the months since launch, a number of performance tests and calibrations have been carried out and are continuing. These tests demonstrate that the instrument is performing very well. We present here a synopsis of the results to date.

Image motion compensation by servocontrolled tilt of the secondary mirror is applied in a 40-cm diam f/7.5 Cassegrainian balloon-borne telescope. A tilted-aplanatic configuration is used, i.e., the mirrors are aspherized to render the stabilized image free of third-order coma. A spatial resolution of 2 sec of arc is maintained in the presence of pointing errors up to 10 min of arc. The most important remaining aberrations are third-order astigmatism and fifth-order spherical aberration. For the latter, a general expression is presented that can also be applied to other two-mirror telescopes.

One second of arc pointing accuracy has been achieved by servocontrolling the secondary mirror of a Dall-Kirkham telescope flown in an Aerobee 150 rocket. The primary mirror is weight-relieved, mounted at its nodal line and can resolve 2 arc sec. An objective LiF prism mounted near the focal plane provides a lowresolution far uv spectrum suitable for studying planetary atmospheres. Solar blind photomultiplier tubes with pulse counting electronics provide a dark current background of less than 1 count/sec. Spectra of Venus, Jupiter and eta Ursa Majoris (U Ma) were obtained in a flight from White Sands, New Mexico, on 5 December 1967. Further flights are planned with the recovered package.

Two methods of off-set sun-tracking are described which were developed as part of the balloon-astronomy program of The Johns Hopkins University for daytime observations of the planet Venus. The performance of the system in flight, while subject to oscillations in the suspension system, is discussed.

The aim of this work is to present experimentally evaluated effective roughnesses (z(oe)) of a partly forested landscape. Although the ratio of boundary-layer height to obstacle size was only of the order of 50, there still seemed to exist a height range of 75-200 m where surface-layer similarity was approximately valid. Attempts were made to use conventional wind profile analysis to evaluate z(oe), but the small height range and the large number of variables initially led to unacceptable uncertainties. Fixing the displacement height z(d), rather than fitting it, reduced the data scatter to an acceptable level. The profile-derived roughness lengths z(op) obtained in this way were in good agreement with previous work, and with an alternative roughness length estimate z(of) for which flux-derived profile parameters u* and theta* were used. This implies that the profile-derived roughnesses were consistent with the measured surface-layer momentum flux. Comparison of both roughness estimates also yielded an improved estimate of the displacement height. Besides this, the authors tested a landscape roughness evaluation method which makes use of the gustiness parameter T-u = sigma(u)/U in the surface layer. The results obtained by this method were in fair agreement with the profile-derived data. In previous work, the gustiness method was advocated because it could be used at relatively low levels, perhaps even within the roughness sub-layer. At the present measuring Site, this was not the case as the gustiness method was only valid in an approximate way, and for a limited height range.

Water vapor in the atmosphere of Venus was discovered in November 1959 by observations made at 80000-ft. altitude with a manned balloon-telescope system. This result was confirmed and measured far more precisely in February 1964 with an automatic unmanned system. The method of observing Venus water-vapor absorption in the 1.13-μ band, and the interpretation of that absorption, are described.
