Are ugly products cool? A study on rebelliousness and product design preferences

Previous research has shown that consumers often prefer aesthetically pleasing over ugly products. However, a question arises whether this is always the case. This research examines whether consumers who are rebellious may perceive ugly products as cool and subsequently prefer these over beautiful ones. To test this prediction, an experiment was conducted ,and data was analyzed using Hayes Model 1, ANOVA and ANCOVA. The results showed that rebelliousness is not related to perception of coolness on ugly products, but originality is. Finally, possible future mechanisms are suggested, and managerial implications are discussed based on the findings

Cosmogenic neutron production at the Sudbury Neutrino Observatory

Neutrons produced in nuclear interactions initiated by cosmic-ray muons present an irreducible background to many rare-event searches, even in detectors located deep underground. Models for the production of these neutrons have been tested against previous experimental data, but the extrapolation to deeper sites is not well understood. Here we report results from an analysis of cosmogenically produced neutrons at the Sudbury Neutrino Observatory. A specific set of observables are presented, which can be used to benchmark the validity of geant4 physics models. In addition, the cosmogenic neutron yield, in units of 10-4 cm2/(g·μ), is measured to be 7.28±0.09(stat)-1.12+1.59(syst) in pure heavy water and 7.30±0.07(stat)-1.02+1.40(syst) in NaCl-loaded heavy water. These results provide unique insights into this potential background source for experiments at SNOLAB

Ionization Electron Signal Processing in Single Phase LArTPCs II. Data/Simulation Comparison and Performance in MicroBooNE

The single-phase liquid argon time projection chamber (LArTPC) provides a large amount of detailed information in the form of fine-grained drifted ionization charge from particle traces. To fully utilize this information, the deposited charge must be accurately extracted from the raw digitized waveforms via a robust signal processing chain. Enabled by the ultra-low noise levels associated with cryogenic electronics in the MicroBooNE detector, the precise extraction of ionization charge from the induction wire planes in a single-phase LArTPC is qualitatively demonstrated on MicroBooNE data with event display images, and quantitatively demonstrated via waveform-level and track-level metrics. Improved performance of induction plane calorimetry is demonstrated through the agreement of extracted ionization charge measurements across different wire planes for various event topologies. In addition to the comprehensive waveform-level comparison of data and simulation, a calibration of the cryogenic electronics response is presented and solutions to various MicroBooNE-specific TPC issues are discussed. This work presents an important improvement in LArTPC signal processing, the foundation of reconstruction and therefore physics analyses in MicroBooNE.Comment: 54 pages, 36 figures; the first part of this work can be found at arXiv:1802.0870

Design and construction of the MicroBooNE Cosmic Ray Tagger system

The MicroBooNE detector utilizes a liquid argon time projection chamber (LArTPC) with an 85 t active mass to study neutrino interactions along the Booster Neutrino Beam (BNB) at Fermilab. With a deployment location near ground level, the detector records many cosmic muon tracks in each beam-related detector trigger that can be misidentified as signals of interest. To reduce these cosmogenic backgrounds, we have designed and constructed a TPC-external Cosmic Ray Tagger (CRT). This sub-system was developed by the Laboratory for High Energy Physics (LHEP), Albert Einstein center for fundamental physics, University of Bern. The system utilizes plastic scintillation modules to provide precise time and position information for TPC-traversing particles. Successful matching of TPC tracks and CRT data will allow us to reduce cosmogenic background and better characterize the light collection system and LArTPC data using cosmic muons. In this paper we describe the design and installation of the MicroBooNE CRT system and provide an overview of a series of tests done to verify the proper operation of the system and its components during installation, commissioning, and physics data-taking

A Deep Neural Network for Pixel-Level Electromagnetic Particle Identification in the MicroBooNE Liquid Argon Time Projection Chamber

We have developed a convolutional neural network (CNN) that can make a pixel-level prediction of objects in image data recorded by a liquid argon time projection chamber (LArTPC) for the first time. We describe the network design, training techniques, and software tools developed to train this network. The goal of this work is to develop a complete deep neural network based data reconstruction chain for the MicroBooNE detector. We show the first demonstration of a network's validity on real LArTPC data using MicroBooNE collection plane images. The demonstration is performed for stopping muon and a $\nu_\mu$ charged current neutral pion data samples

Expansão do sector oleícola e os factores críticos de sucesso segmento gourmet nas estratégias de internacionalização das empresas Portuguesas

Mestrado em MarketingApós o acentuado decréscimo na produção de azeite verificado nas décadas de 60 a 80, é notório que os últimos anos têm sido de recuperação em Portugal: nos últimos 5 anos a produção nacional anual tem demonstrado um crescimento de 50%. Num país como Portugal, em que o mercado interno é de apenas 10 milhões de consumidores, a exportação surge como uma via de sentido obrigatório indispensável para o crescimento económico. Neste sentido, apesar de os países do mediterrâneo serem os principais consumidores de azeite, esta tendência tem vindo a expandir-se e existem oportunidades significativas em novas partes do mundo como sudeste da Ásia, China e países da América Latina. Para tal, uma das estratégias que tem vindo a ser adoptada pelas empresas Portuguesas é a introdução do segmento gourmet, que sendo um posicionamento diferente tem inúmeras características de marketing que vão para além da qualidade do produto e que precisam de ser analisadas e trabalhadas. Ter o produto certo não é suficiente, é necessário dá-lo a conhecer. Assim, o presente estudo vem analisar as estratégias que as empresas portuguesas de azeite utilizam na exportação deste novo segmento.After the significant decrease in the production of Olive Oil that was observed in the 60's and the 80's, it's visible that the last years have been of recovery for Portugal: in the last 5 years the annual national production report shows that there's a growth of 50%. In a country like Portugal, in which the internal market is just about 10 million consumers, exportation urges as a way that must be followed for economical growth. In this sense, although Mediterranic countries represent the main consumers of Olive Oil, this tendency is expanding to significant opportunities in new regions of the world such as Southeast Asia, China and South America countries. To do that, one of the strategies that is being used by Portuguese companies, is the introduction of the Gourmet segment. Having a different positioning, this segment has several specific marketing characteristics that needs to be addressed, analyzed and worked out. Have the right product is not enough, it?s necessary to give it to know. This way, these studies analyze strategies of internationalization of Olive oil Portuguese companies, for this segment
