Growing interest in quantitative studies of social movements and protest cycles attests to the vigor of protest event analysis as a strategy for investigating the protopolitical processes of collective claimsmaking in democratic states and emerging democracies. Increasing investments in protest events research has also led to growing concern about sources of measurement error that stem from reliance on media data sources. Using Blalock's conception of auxiliary measurement models, this article traces two alternative treatments of measurement bias in the literature on events analysis. The two approaches, characterized here as "media theory" and "representational," differ in the degree to which they accept media data as an adequate representation of protest event reality. Recent work that attempts to establish empirically the relationship between media data and alternative data sources on protest events promises an empirical base for examining the assumption of stable media bias that underlies representational approaches. Finally, the conclusions suggest some weaknesses in the empirical base for theorizing from media-based event analyses.

The aim of this paper is to find and compare existing solutions of complex event processing platforms (CEP). CEP platforms generally serve for processing and/or predicting of high frequency data. We intend to use CEP platform for processing of complex time series and integrate a solution for newly proposed method of decision making. The decision making process will be described by formal grammar. As there are lots of CEP solutions we will take the following characteristics under consideration - the processing in real time, possibility of processing of high volume data from multiple sources, platform independence, platform allowing integration with user solution and open license. At first we will talk about existing CEP tools and their specific way of use in praxis. Then we will mention the design of method for formalization of business rules used for decision making. Afterwards, we focus on two platforms which seem to be the best fit for integration of our solution and we will list the main pros and cons of each approach. Next part is devoted to benchmark platforms for CEP. Final part is devoted to experimental measurements of platform with integrated method for decision support.

This paper aims to develop event quality measurement scale in running event context. This particular type of track event became more popular in many countries in recent years. The Big Five destinations of running events: Berlin, Boston, Chicago, London, and New York are among those final destinations of runners around the world. To attract these runners, quality of the event would be the key success factor. For this paper, the measurement scale has been divided into three dimensions: physical environment, staff attitude and experience of runner after participating in the running event. Samples has been selected using, first, cluster sampling method according to the running event organized in Bangkok during March 2019. The Ultra Park Run Thailand 100 was selected due to the number of participants, approximately 5,000 runners, and it was the only big running event during that time. Second, 109 runners who participated in running events has been selected using simple random sampling method. There are 18 items for this measurement scale. The result of exploratory factor analysis illustrated that all items have factor loading more than 0.4 exempt one item, st-att5 has factor loading close to 0.4 with communalities is 0.268, thus it is deleted during this stage. Furthermore, result of reliability coefficient test shows that all dimensions have Cronbach’s a higher than 0.7. The alpha coefficient for physical environment dimension was 0.868, staff attitude was 0.821, and experience was 0.771. Therefore, all items are correlate to each other and it is sufficient to explain the running event quality construct.

ERP is common abbreviation for event-related brain potentials, which are measured and used in clinical practice as well as in research practice. Contemporary studies of placebo effect are often based on functional neuromagnetic resonance (fMRI), positron emission tomography (PET), and event related potentials (ERP). This paper considers an ERP instrumentation system used in experimental researches of placebo effect. This instrumentation system can be divided into four modules: electrodes and cables, conditioning module, digital measurement module, and PC module for stimulations, presentations, acquisition and data processing. The experimental oddball paradigm is supported by the software of the instrumentation.

Diese Dissertation beschreibt eine Messung von hadronischen Ereignisformvariablen (event shapes) in Protonkollisionen mit einer Schwerpunktsenergie von 7 TeV am Large Hadron Collider (LHC) am CERN (Conseil Europeenne pour la Recherche Nucleaire) bei Genf (Schweiz). Die analysierten Daten mit einer integrierten Luminosität von 1.1 inversen fb wurden im Jahr 2011 mit dem ATLAS Experiment aufgenommen. Für die Analyse wurden solche Ereignisse ausgewählt, in deren harten Streuprozessen ein Z-Boson produziert wurde, welches entweder in ein Elektron-Positron-Paar oder ein Muon-Antimuon-Paar zerfällt. Die Observablen wurden mit sämtlichen rekonstruierten Spuren innerhalb der Akzeptanz des inneren Spurdetektors (Inner Detector) von ATLAS außer denen der Leptonen des Zerfalls des Z-Bosons berechnet. Somit handelt es sich hierbei um die erste Messung dieser Art. Anschließend wurden die Observablen auf Untergrundprozesse mit auf Daten basierenden Methoden korrigiert wobei ein neues Verfahren für die Korrektur des sogenannten Pile-up (Überlagerung mehrerer Proton-Proton Wechselwirkungen) entwickelt und erfolgreich zur Anwedung gebracht wurde. Schließlich wurden die gemessenen Verteilungen entfaltet. Die so erhaltenen Daten sind insbesondere sensitiv auf das sogenannte Underlying Event und können direkt mit Monte-Carlo-Ereignisgeneratoren ohne aufwändige Simulation des ATLAS-Detektors verglichen werden. Abschließend wurde versucht die Modellparameter in den Simulationsprogrammen Pythia8 und Sherpa mithilfe der gewonnenen Daten durch eine bessere Abstimmung (Tuning) zu verbessern. Hierbei zeigte sich, dass das zugrunde liegende Sjostrand-Zijl Modell nicht ausreicht, um eine adäquate Beschreibung der gemessenen Verteilungen zu erreichen. This thesis describes a measurement of hadron-collider event shapes in proton-proton collisions at a centre of momentum energy of 7 TeV at the Large Hadron Collider (LHC) at CERN (Conseil Europeenne pour la Recherche Nucleaire) located near Geneva (Switzerland). The analysed data (integrated luminosity: 1.1 inverse fb) was recorded in 2011 with the ATLAS-experiment. Events where a Z-boson was produced in the hard sub-process which subsequently decays into an electron-positron or muon-antimuon pair were selected for this analysis. The observables are calculated using all reconstructed tracks of charged particles within the acceptance of the inner detector of ATLAS except those of the leptons of the Z-decay. Thus, this is the first measurement of its kind. The observables were corrected for background processes using data-driven methods. For the correction of so-called pile-up (multiple overlapping proton-proton collisions) a novel technique was developed and successfully applied. The data was further unfolded to correct for remaining detector effects. The obtained distributions are especially sensitive to the so-called Underlying Event and can be compared with predictions of Monte-Carlo event-generators directly, i.e. without the necessity of running time-consuming simulations of the ATLAS-detector. Finally, it was tried to improve the predictions of the event generators Pythia8 and Sherpa by finding an optimised setting of relevant model parameters in a technique called Tuning. It became apparent, however, that the underlying Sjostrand-Zijl model is unable to give a good description of the measured event-shape distributions.

Event-related potentials have been found to be a useful indicator of brain states and brain abnormality. The contingent negative variation, P300 and bereitschafts potential are well researched event-related potentials of particular interest. Many factors have to be considered in the design of measurement systems to record multiple channels of these signals accurately. The correlation between channels must be high and channel noise and distortion must be minimal, whilst the system as a whole must meet the requirements of the medical safety standards. For further research there was found to be a requirement for a dedicated thirty-two channel ERP measurement system that met these criteria. This has been achieved in a PC based system that utilises simultaneous sampling of all channels, and filters that extend to very low frequencies. Software control of the system enables user adjustment of recording parameters and paradigm implementation. Data processing using high level software enables digital signal processing techniques to be applied for further noise removal and signal analysis. The system has been tested using synthetically generated signals and by limited recording of the three ERPs. The results prove that the system is a suitable tool for high accuracy, multi-channel recording of ERPs.

Liu, Jian. "Ambulatory Fall Event Detection with Integrative Ambulatory Measurement (IAM) Framework." Diss., Virginia Tech, 2008. http://hdl.handle.net/10919/77184.
Injuries associated with fall accidents pose a significant health problem to society, both in terms of human suffering and economic losses. Existing fall intervention approaches are facing various limitations. This dissertation presented an effort to advance indirect type of injury prevention approach. The overall objective was to develop a new fall event detection algorithm and a new integrative ambulatory measurement (IAM) framework which could further improve the fall detection algorithm's performance in detecting slip-induced backward falls. This type of fall was chosen because slipping contributes to a major portion of fall-related injuries. The new fall detection algorithm was designed to utilize trunk angular kinematics information as measured by Inertial Measurement Units (IMU).
Two empirical studies were conducted to demonstrate the utility of the new detection algorithm and the IAM framework in fall event detection. The first study involved a biomechanical analysis of trunk motion features during common Activities of Daily Living (ADLs) and slip-induced falls using an optical motion analysis system. The second study involved collecting laboratory data of common ADLs and slip-induced falls using ambulatory sensors, and evaluating the performance of the new algorithm in fall event detection.
Results from the current study indicated that the backward falls were characterized by the unique, simultaneous occurrence of an extremely high trunk extension angular velocity and a slight trunk extension angle. The quadratic form of the two-dimensional discrimination function showed a close-to-ideal overall detection performance (AUC of ROCa = 0.9952). The sensitivity, specificity, and the average response time associated with the specific configuration of the new algorithm were found to be 100%, 95.65%, and 255ms, respectively. The individual calibration significantly improved the response time by 2.4% (6ms).
Therefore, it was concluded that slip-induced backward fall was clearly distinguishable from ADLs in the trunk angular phase plot. The new algorithm utilizing a gyroscope and orientation sensor was able to detect backward falls prior to the impact, with a high level of sensitivity and specificity. In addition, individual calibration provided by the IAM framework was able to further enhance the fall detection performance. Ph. D.

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California A fiber optic event timing system was developed for the High Speed Test Track at
Holloman Air Force Base, Alamogordo, NM. The system uses fiber optic sensors to detect
the passage of rocket sleds by different stations along the track. The sensors are connected
by fiber optic cables to an electronics package that records the event time to a resolution of
100 nanoseconds. By use of a GPS receiver as the timebase, the event time is stored to an
absolute accuracy of 300 nanoseconds. Custom VMEbus boards were developed for the
event timing function, and these boards are controlled by a programmable high speed
sequencer, which allows for complicated control functions. Each board has 4 electro-optic
channels, and multiple boards can be used in a VMEbus card cage controlled by a single
board computer. The system has been tested in a series of missions at the Test Track.

Denna kandidatuppsats inom företagsekonomi behandlar ämnet eventmarknadsföring och merinriktat hur mätning och utvärdering går till hos företag och organisationer samt vilkakomplikationer som finns kring detta. Studien är gjord med kvalitativ metod och har baseratspå teorier samt praktiska exempel som samlats in via en intervjumetod hos företag ochorganisationer.Uppsatsens huvudfokus är ämnet eventmarknadsföring, och den inriktas främst på hurmätning och utvärdering av marknadsföringsmetoden går till. Just mätning och utvärdering aveventmarknadsföring är sparsamt beforskat och det finns en avsaknad av kunskap om hur manpraktiskt tillämpar detta i organisationer och företag. Dock kan man se att den traditionellamarknadsföringens plats håller på att minska och eventmarknadsföring går stadigt uppåt.Exakt vad eventmarknadsföring innebär är aningen diffust då alla verkar ha sin egendefinition på ämnet men man kan kortfattat förklara det som att det handlar om att användasig av event av olika slag för att kommunicera ut en produkt eller ett budskap. Trots att mångaanvänder sig av denna metod är det ofta som man inte genomför någon utvärdering avresultatet och tidigare var detta inget problem men nu efterfrågas det mer och mer av företagoch i organisationer. På grund av detta är det av mångas intresse att lära sig mer kringmätning och utvärdering av eventmarknadsföring.Under våra intervjuer använde vi oss av en intervjuguide för att lämpliga frågor skulle ställastill respondenterna samt för att säkerställa att vi fick in samma information från de olikaintervjuerna. Intervjuguiden utformades utifrån den teori vi hittade och användes till de femintervjuer som genomfördes på fem olika företag. Respondenterna verkar inom flera olikabranscher och på så vis har vi fått inblick från olika branscher till uppsatsen.Teori och empiri indikerar att det är ett ytterst komplext ämne vi har undersökt och därför hardet varit svårt att dra några klara slutsatser. Det vi har kunnat konstatera är att det inte finnsnågon samordnad sanning kring hur mätning och utvärdering går till eftersom det är olikaberoende på vilken bransch du tillhör och vad du har för mål med eventet. Det finns hellerinte något standardiserat utvärderingsverktyg, men det efterfrågas delvis av både forskare ochvåra respondenter. Dessutom har vi konstaterat att man måste sätta mål redan under planeringför att man ska kunna mäta och utvärdera i efterhand. Undersökningen visar även atteventmarknadsföring är en lämplig metod att använda sig av då man lätt kan få en dialogmellan företag och konsumenten där man kan förändra attityd- och köpbeteendet. This business bachelor thesis deals with the subject event marketing and more focused onhow to measure and evaluate this subject within companies and organisations and whatcomplications that surround this. The study is made with a qualitative method and is based ontheories and practical examples, which are gathered through interviews at companies andorganisations.Measurement and evaluation of event marketing is sparingly researched and there is a lack ofknowledge on how to practically use this in companies and organisations. However, one cansee that the traditional marketing space is shrinking and event marketing is rising. What eventmarketing means exactly is somewhat diffuse since everyone seems to have their owndefinition of the topic - but one can briefly explain that it is about making use of events ofvarious kinds to communicate a product or a message. Even though this is a method that isoften used the result is rarely evaluated. This was not a problem a few years back but nowcompanies and organisations demand this more and more. Because of this, there is a lot ofinterest in learning more about the measurement and evaluation of event marketing.During our interviews we used an interview guide to make sure we used appropriate questionsto our respondents and to make sure we got the same information from the differentinterviews. The interview guide was created from the theory we found and was used in thefive interviews conducted at five different companies. Our respondents operate in variousindustries and thus we have gained insight from various sectors of the paper.Theory and empirical evidence indicates that there is an extremely complex topic, we haveinvestigated and therefore it has been difficult to draw any clear conclusions. What we haveobserved is that there is no coordinated truths about how measurement and evaluation is donebecause it is different depending on what industry you belong to and what your goals are withthe event. Nor are there any standardized evaluation tools, but are partly requested by bothscientists and our respondents. Moreover, we have noted that you have to set goals alreadyduring planning in order to be able to measure and evaluate afterwards. The survey alsoshows that event marketing is an appropriate method to use because you can easily get adialogue between companies and consumers where they can change attitudes and purchasingbehaviour.

AbstractA modern state-of-the-art “quantum measurement” [The term “quantum measurement” as used here implies that parameters of atomic particles are measured that emerge from a single scattering process of quantum particles.] of momentum and position of a single electron at a given time [“at a given time” means directly after the scattering process. (It should be noticed that the duration of the reaction process is typically extremely short => attoseconds).] and the precision limits for their experimental determination are discussed from an experimentalists point of view. We show—by giving examples of actually performed experiments—that in a single reaction between quantum particles at a given time only the momenta of the emitted particles but not their positions can be measured with sub-atomic resolution. This fundamental disparity between the conjugate variables of momentum and position is due to the fact that during a single-event measurement only the total momentum but not position is conserved as function of time. We highlight, that (other than prevalently perceived) Heisenberg’s “Uncertainty Relation” UR [1] does not limit the achievable resolution of momentum in a single-event measurement. Thus, Heisenberg’s statement that in a single-event measurement only either the position or the momentum (velocity) of a quantum particle can be measured with high precision contradicts a real experiment. The UR states only a correlation between the mean statistical fluctuations of a large number of repeated single-event measurements of two conjugate variables. A detailed discussion of the real measurement process and its precision with respect to momentum and position is presented.

We develop a model that permits the estimation of a term structure of both expectations and forecast uncertainty for application to professional forecasts such as the Survey of Professional Forecasters (SPF). Our approach exactly replicates a given data set of predictions from the SPF (or a similar forecast source) without measurement error. Our model captures fixed horizon and fixed-event forecasts, and can accommodate changes in the maximal forecast horizon available from the SPF. The model casts a decomposition of multi-period forecast errors into a sequence of forecast updates that may be partially unobserved, resulting in a multivariate unobserved components model. In our empirical analysis, we provide quarterly term structures of expectations and uncertainty bands. Our preferred specification features stochastic volatility in forecast updates, which improves forecast performance and yields model estimates of forecast uncertainty that vary over time. We conclude by constructing SPF-based fan charts for calendar-year forecasts like those published by the Federal Reserve.
