Abstract The limited influence of corrective messages is one of the most striking observations in the misperceptions literature. We elaborate on this well-known outcome, showing that correction effectiveness varies according to recipients’ judgment strategy. Using data from two online experiments, we demonstrate that individuals’ responses to corrective messages are less biased by prior attitudes when they engage in on-line rather than memory-based processing. We also show that individuals are more responsive to one-sided messages under conditions of on-line rather than memory-based processing. Unexpectedly, two-sided messages, which repeat the inaccuracy before correcting it, performed better than one-sided messages among individuals using memory-based processes. These findings contribute to our understanding of fact-checking, and suggest strategies that could help promote greater responsiveness to corrective messages.

Transfer alignment is the process of initialising and calibrating a weapon INS using data from the host aircraft's navigation system. To determine which transfer alignment technique performs best, different design options have been assessed, supported by simulation work. The dependence of transfer alignment performance on environmental factors, such as manoeuvres, alignment duration, lever arm and inertial sensor quality has also been studied. ‘Rapid’ alignment, using attitude as well as velocity measurements was found to perform better than ‘conventional’ techniques using only velocity. Innovative developments include the estimation of additional acceleration and gyro states and estimation of force dependent relative orientation, which has enabled robust alignment using wing rock manoeuvres, which do not require the pilot to change trajectory. Transfer alignment has been verified in real-time by flight trials on a Tornado aircraft. In addition, techniques have been developed to prevent transients in the aircraft integrated navigation solution following GPS re-acquisition after an outage of several minutes from disrupting the transfer alignment process.

Abstract. The high spatial and temporal variability of aerosols make networks capable of measuring their properties in near real time of high scientific interest. In this work we present and discuss results of an aerosol optical depth algorithm to be used in the European Brewer Network, which provides data in near real time of more than 30 spectrophotometers located from Tamanrasset (Algeria) to Kangerlussuaq (Greenland). Using data from the Brewer Intercomparison Campaigns in the years 2013 and 2015, and the period in between, plus comparisons with Cimel sunphotometers and UVPFR instruments, we check the precision, stability, and uncertainty of the Brewer AOD in the ultraviolet range from 300 to 320 nm. Our results show a precision better than 0.01, an uncertainty of less than 0.05, and a stability similar to that of the ozone measurements for well-maintained instruments. We also discuss future improvements to our algorithm with respect to the input data, their processing, and the characterization of the Brewer instruments for the measurement of aerosols.

The Impact

The study of networks has been propelled by improvements in computing power, enabling our ability to mine and store large amounts of network data. Moreover, the ubiquity of the internet has afforded us access to records of interactions that have previously been invisible. We are now able to study complex networks with anywhere from hundreds to billions of nodes; however, it is difficult to visualize large networks in a meaningful way. We explore the process of visualizing real-world networks. We first discuss the properties of complex networks and the mechanisms used in the network visualizing software Gephi. Then we provide examples of voting, trade, and linguistic networks using data extracted from on-line sources. We investigate the impact of hidden community structures on the analysis of these real-world networks.

This paper investigates the impact of having open 400 meter (400 m) runners on NCAA relay teams. Using data from 2012–2016 containing the top 100 4 × 400 m in each NCAA Division relay times for each year, it is found that more 400 m specialists lead to an increase in the overall performance of the team, measured by a decrease in relay times. The effect is examined across Division I–III NCAA track teams. The results are consistent across each division. We view this as a test of the role of specialization on performance. Using runners who specialize in 400 m races should increase overall team performance as long as specialization does not lead to an inefficient allocation of team human capital. An additional performance measure is used examining the difference between projected and actual relay times. Divisions I and II are found to perform better than projected with an increase in 400 m runners, but there is no effect found in Division III.

AbstractWe employ Pan-STARRS photometry, Gaia trigonometric parallaxes, modern stellar evolution and atmosphere models, and our Bayesian fitting approach to determine cooling and total ages for 159,238 white dwarfs. In many cases we are able to derive precise ages (better than 5%) for individual white dwarfs. These results are meant for broad use within the white dwarf and stellar astrophysics communities and we plan to make available on-line the posterior distributions for cooling age, total age, initial stellar mass, and other parameters.

Purpose This study aims to examine the relationship between organizational capacity, slack resource, platform strategic choice and firm performance. It also tackles the endogenous issues regarding the strategic choice of platform types. Design/methodology/approach This study uses Heckman’s two-stage procedures to examine the relationship between the variables. The sample in this study comes from Compustat annual company and segment files. The sample used in the main analysis consists of 252 individual corporations globally and 3,528 firm-year observations from 2004–2017. Findings The empirical results suggest that: (1) firms are more likely to develop physical platforms than virtual platforms when they possess higher levels of available slack, potential slack, research and development (R&D) capacity and marketing capacity; (2) in general, firms developing physical platforms perform better than firms developing virtual platforms after the endogeneity bias are controlled; and (3) firms that choose to develop physical platforms perform better than if they had chosen to develop virtual platforms. Research limitations/implications This study contributes to the platform research literature by proposing the endogenous role of platform type choice in firm performance in the context of the retail industry. Prior conceptual and theoretical platform studies have seldom focused on the retail industry through a strategic choice perspective. Furthermore, one of the contributions of this study is the derivation of empirical support for the research’s prediction using data from actual firms carried out by global physical and virtual platform companies. This study also presents many opportunities for further explorations on the relationship between firm strategic choice and firm performance in the context of platform retail industry. Practical implications The findings of this study suggest that firms must realize that their performance is not necessarily affected by these platform type choice determinants in terms of potential slack, available slack, R&D capacity and marketing capacity. By contrast, they should pay more attention to developing physical platforms if it is possible. The study findings indicate that although virtual platforms have grown rapidly because of the development of technology, firm performance is at all times superior when firms choose to develop physical platforms. Originality/value Prior platform studies have focused on the topic of network structure, platform architecture, pricing strategy, platform leadership and platform design and governance within the context of video game industry, software industry, hardware industry and telecommunications industry. Seldom of them focus on other industries through a strategic choice perspective. Furthermore, one of the contributions of this study is the derivation of empirical support for the research’s prediction using data from actual firms carried out by global physical and virtual platform companies.

SUMMARYUsing data from 140 experiments conducted at sites throughout England and Wales, a relationship between nitrogen supply and the nitrogen yield of cut grass swards was sought. One linear and three non-linear functions were fitted to the data. The non-linear functions fitted the data slightly better than did the linear and, over the range in nitrogen supply normally found, provided consistent predictions of grass nitrogen yield. The recovery of available nitrogen in the herbage was found to decline with level of nitrogen supply from a potential maximum of 79%.

The paper presents an approach to nonlinear control of dynamic systems using artificial neural networks (ANN). A novel form of ANN, namely, single multiplicative neuron (SMN) model is proposed in place of more traditional multi-layer perceptron (MLP). SMN derives its inspiration from the single neuron computation model in neuroscience. SMN model is trained off-line, to estimate the network weights and biases, using a population based stochastic optimization technique, namely, particle swarm optimization (PSO). Both off-line training and on-line learning of SMN have been considered. The development of the control algorithm is illustrated through the hardware-in-the-loop (HIL) implementation of DC motor speed control in LabVIEW environment. The controller based on SMN performs better than MLP. The simple structure and faster computation of SMN have the potential to make it a preferred candidate for implementation of real-life complex control systems.

The advantages of being able to process marine radar imagery in an on-line computer system have been illustrated by study of some navigational problems. The experiments suggest that accuracies of the order of 100 metres may be obtained in navigation in coastal regions using map overlays with marine radar data. A similar technique using different radar imagery of the same location suggests that the pattern-recognition technique may well yield a position-keeping ability of better than 10 metres.
