Panel design effects on response rates and response quality

To understand changes in individuals' opinions and attitudes it would be bestto collect data through panels. Such panels, however, often cause irritationamong respondents, resulting in low response rates and low response quality.We address whether this problem can be alleviated by designing a panel surveyin an alternative way. For this purpose, we perform two field studies wherewe measure the effects of several panel design characteristics on response ratesand response quality. These characteristics include the number of waves andthe time between subsequent waves, which may either be fixed or random.Our findings suggest that response rates and response quality can be im-proved significantly by surveying at random time intervals. It is then crucialthat panel members are not informed about the dates they will be surveyed,because in this case respondents are less likely to develop expectations as towhen they will be surveyed again. The methodology we put forward can be used to improve the e±ciency of a panel study by carefully calibrating thestudies' panel designs parameters.nonresponse;panel conditioning;randomized sampling;time sampling;panel design

Az ipari parkok a területi versenyképességben: telephelyek vagy fejlesztési csomópontok?

The MATLAB/C program take version 3.1 is a program for simulation of X-ray projections from 3D volume data. It is based on an older C version by Muller-Merbach as well as an extended C version by Turbell. The program can simulate 2D X-ray projections from 3D objects. These data can then be input to 3D reconstruction algorithms. Here however, we only demonstrate a couple of 2D reconstruction algorithms, written in MATLAB. Simple MATLAB examples show how to generate the take projections followed by subsequent reconstruction. Compared to the old take version, the C code have been carefully revised. A preliminary, rather untested feature of using a polychromatic X-ray source with different energy levels was already included in the old take version. The current polychromatic feature X-ray is however carefully tested. For example, it has been compared with the results from the program described by Malusek et al. We also demonstrate experiments with a polychromatic X-ray source and a Plexiglass object giving the beam-hardening artefact. Detector sensitivity for different energy levels is not included in take. However, in section~\refsec:realexperiment, we describe a technique to include the detector sensitivity into the energy spectrum. Finally, an experiment with comparison of real and simulated data were performed. The result wasn't completely successful, but we still demonstrate it. Contemporary analytical reconstruction methods for helical cone-beam CT have to be designed to handle the Long Object Problem. Normally, a moderate amount of over-scanning is sufficient for reconstruction of a certain Region-of-interest (ROI). Unfortunately, for iterative methods, it seems that the useful ROI will diminish for every iteration step. The remedies proposed here are twofold. Firstly, we use careful extrapolation and masking of projection data. Secondly, we generate and utilize projection data from incompletely reconstructed volume parts, which is rather counter-intuitive and contradictory to our initial assumptions. The results seem very encouraging. Even voxels close to the boundary in the original ROI are as well enhanced by the iterative loop as the middle part

The Viking surface sampler

A surface sampler subsystem for the Viking Lander has been designed, fabricated, cleaned, and successfully tested. Testing has included component level tests to qualification environment and subsystem level tests. This development hardware has also been integrated into a System Test Bed (STB) for the lander system. In addition to the normal dynamic and thermal environments the surface sampler hardware has been tested in an aircraft to simulate the effects of the reduced Martian gravity. Although problems have been encountered with the first-build and integration, the basic design appears to be sound and hardware qualification is scheduled for late 1973

Word-level Symbolic Trajectory Evaluation

Symbolic trajectory evaluation (STE) is a model checking technique that has been successfully used to verify industrial designs. Existing implementations of STE, however, reason at the level of bits, allowing signals to take values in {0, 1, X}. This limits the amount of abstraction that can be achieved, and presents inherent limitations to scaling. The main contribution of this paper is to show how much more abstract lattices can be derived automatically from RTL descriptions, and how a model checker for the general theory of STE instantiated with such abstract lattices can be implemented in practice. This gives us the first practical word-level STE engine, called STEWord. Experiments on a set of designs similar to those used in industry show that STEWord scales better than word-level BMC and also bit-level STE.Comment: 19 pages, 3 figures, 2 tables, full version of paper in International Conference on Computer-Aided Verification (CAV) 201

Associative Learning of an Odor to a Sugar-meal by Anopheles gambiae (Diptera: Culicidae)

The abilities of many insects to learn have been well documented. However, a limited number of studies have been conducted to determine associative learning capabilities in medically important insects. To date, no studies of this sort have been carried out with the malaria vector Anopheles gambiae. This research study used Culex pipiens to investigate methods used in a previous study that looked at the learning abilities of Cx. quinquefasciatus to associate an odor (conditioned stimulus) with a sugar-meal (unconditioned stimulus) by individual training and testing. Those methods were then adapted and used to examine associative learning capabilities in An. gambiae by both individual training, and testing with a dual-port olfactometer. Vanilla and almond extracts were used for individual training and testing of Cx. pipiens, but were found to be unsuitable. In order to determine compounds more appropriate than extracts to train and test An. gambiae, two sets of experiments were carried out with chemicals found in honey to determine An. gambiae mosquitoes’ innate responses to them. From those results, phenylacetaldehyde and geranylacetone were chosen to be used for the dual-port olfactometer trials, and linalool oxide and (Z)-β-ocimene were chosen to be used for the individual training and testing of An. gambiae. The results indicate the possibility that An. gambiae mosquitoes can associatively learn and illustrate the need to ensure that all the parameters that may affect the learning abilities and behaviors of mosquitoes are taken into account in the experimental design so that definitive conclusions about their learning abilities can be made.No embarg

Georgiana Duchess of Devonshire: Spark of the Women’s Rights Movement

The late eighteenth century of Great Britain displayed a society influenced by outside thinkers, such as Rousseau, and dealing with the results of the American and French Revolutions. During this time a young women named Georgiana Cavendish began to break the mold that many aristocratic nobles adhered to for many years. The purpose of looking at Georgiana’s life and short career in politics is to show that women indeed could campaign in a very effective way. Though her campaigning got her friend a seat in Parliament, her exposure to the public during this time caused her and the person she campaigned for to lose some respect in the eyes of the public
