A Good Night Out: An Investigation into Alcohol Related Consumption and Behaviour Cultures in Young Adults

Purpose – The purpose of this paper is to investigate drinking patterns; attitudes towards alcohol consumption and alcohol related behaviours amongst differing groups of young adults. A further aim is to investigate whether the drinking behaviours of undergraduate populations can be considered to be representative of young adult behaviours in general. Design/methodology/ approach – Four groups of young adult alcohol consumers were identified. The participants in the first two groups were aged between 18 and 23, one group being undergraduates and the second non-graduates in work. Participants in the second two groups were aged between 24 and 29, one group comprising graduates in work, the second non-graduates in work. 120 questionnaires were completed; thirty in each sample group, with an even gender distribution. Follow up one-to-one interviews were carried out with representatives from each group. Findings – Although a small study it is evident that whilst there are some similarities in behaviours between the differing sample groups significant differences in alcohol related behaviours dominate. Practical Implications – The results suggest that utilising the results of research carried out amongst student populations to inform government policies with regard to the behaviour of young adults in general is unlikely to be successful in changing drinking behaviours. Originality value – This paper produces new insights into current drinking cultures and attitudes towards drinking in differing groups of young adults. Specifically it compares behavioural norms between graduate and non-graduate populations challenging much current research which is based upon student samples as being representative of the young adult population as a whole

Multistatic human micro-Doppler classification of armed/unarmed personnel

Classification of different human activities using multistatic micro-Doppler data and features is considered in this paper, focusing on the distinction between unarmed and potentially armed personnel. A database of real radar data with more than 550 recordings from 7 different human subjects has been collected in a series of experiments in the field with a multistatic radar system. Four key features were extracted from the micro-Doppler signature after Short Time Fourier Transform analysis. The resulting feature vectors were then used as individual, pairs, triplets, and all together before inputting to different types of classifiers based on the discriminant analysis method. The performance of different classifiers and different feature combinations is discussed aiming at identifying the most appropriate features for the unarmed vs armed personnel classification, as well as the benefit of combining multistatic data rather than using monostatic data only

Personnel recognition based on multistatic micro-Doppler and singular value decomposition features

The use of micro-Doppler signatures experimentally collected by a multistatic radar system to recognise and classify different people walking is discussed. A suitable feature based on singular value decomposition of the spectrograms is proposed and tested with different types of classifiers. It is shown that high accuracy of between 97 and 99% can be achieved when multistatic data are used to perform the classification

Experimental analysis of multistatic multiband radar signatures of wind turbines

This study presents the analysis of recent experimental data acquired using two radar systems at S-band and X-band to measure simultaneous monostatic and bistatic signatures of operational wind turbines near Shrivenham, UK. Bistatic and multistatic radars are a potential approach to mitigate the adverse effects of wind farm clutter on the performance of radar systems, which is a well-known problem for air traffic control and air defence radar. This analysis compares the simultaneous monostatic and bistatic micro-Doppler signatures of two operational turbines and investigates the key differences at bistatic angles up to 23°. The variations of the signature with different polarisations, namely vertical transmitted and vertical received and horizontal transmitted and horizontal received, are also discussed

Landau Ginzburg Theory and Nuclear Matter at Finite Temperature

Based on recent studies of the temperature dependence of the energy and specific heat of liquid nuclear matter, a phase transition is suggested at a temperature $\sim .8$ MeV. We apply Landau Ginzburg theory to this transition and determine the behaviour of the energy and specific heat close to the critical temperature in the condensed phase.Comment: 10 pages, Revte

Measurement and Analysis of Multiband Bistatic and Monostatic Radar Signatures of Wind Turbines

This paper presents the results of recent measurements taken with two radar systems to measure the simultaneous monostatic and bistatic signature of wind turbines, at S-band and X-band. Coherent monostatic and bistatic data was collected with the University College London (UCL) NetRAD 2.4 GHz radar, and the Cranfield University CW radar operating at X-band. This initial analysis shows the bistatic Doppler signature of wind turbines and informs on the key differences seen at modest bistatic angles. Polarimetric variations are also analysed via data gathered using co-polarised VV and HH and cross-polarised VH components

UNDERSTANDING THE CONNECTIONS BETWEEN GOAL AMBIGUITY, LATERAL ORGANIZATIONAL COMMUNICAITON, AND JOB SATISFACTION

Public management scholars consistently argue that clear goals increase employee effectiveness. As goals direct attention and effort toward a specific target, the knowledge of one’s organizational connectedness has the potential to increase job satisfaction. While the positive correlations between clear goals and job satisfaction are also well known among management scholars, little research examines lateral organizational communication’s importance for goal clarification, and further increasing job satisfaction. Findings from two regression models reveal that the while clearer goals indicate higher job satisfaction, employee job satisfaction is more pronounced in the presence of effective lateral organizational communication
