description: We examine the constraints cosmological observations can place on any trans-Planckian corrections to the primordial spectrum of perturbations underlying the anisotropies in the Cosmic Microwave Background. We focus on models of trans-Planckian physics which lead to a modulated primordial spectrum. Rather than looking at a generic modulated spectrum, our calculations are based on a specific model, and are intended as a case study for the sort of constraints one could hope to apply on a well-motivated model of trans-Planckian physics. We present results for three different approaches -- a grid search in a subset of the overall parameter space, a Fisher matrix estimate of the likely error ellipses, and a Monte Carlo Markov Chain fit to a simulated CMB sky. As was seen in previous analyses, the likelihood space has multiple peaks, and we show that their distribution can be reproduced via a simple semi-analytic argument. All three methods lead to broadly similar results. We vary 10 cosmological parameters (including two related to the trans-Planckian terms) and show that the amplitude of the tensor perturbations is directly correlated with the detectability of any trans-Planckian modulation. We argue that this is likely to be true for any trans-Planckian modulation in the paradigm of slow-roll inflation. For the specific case we consider, we conclude that if the tensor to scalar ratio, $r \sim 0.15$, the ratio between the inflationary Hubble scale $H$, and the scale of new physics $M$ has to be on the order of 0.004 if the modulation is detectable at the 2$σ$ level. For a lower value of $r$, the bound on $H/M$ becomes looser.

description: Bars inhabit the majority of local-Universe disk galaxies and may be important drivers of galaxy evolution through the redistribution of gas and angular momentum within disks. We investigate the star formation and gas properties of bars in galaxies spanning a wide range of masses, environments, and star formation rates using the MaNGA galaxy survey. Using a robustly-defined sample of 684 barred galaxies, we find that fractional (or scaled) bar length correlates with the host's offset from the star-formation main sequence. Considering the morphology of the H$α$ emission we separate barred galaxies into different categories, including barred, ringed, and central configurations, together with H$α$ detected at the ends of a bar. We find that only low-mass galaxies host star formation along their bars, and that this is located predominantly at the leading edge of the bar itself. Our results are supported by recent simulations of massive galaxies, which show that the position of star formation within a bar is regulated by a combination of shear forces, turbulence and gas flows. We conclude that the physical properties of a bar are mostly governed by the existing stellar mass of the host galaxy, but that they also play an important role in the galaxy's ongoing star formation.

description: This report summarizes preliminary findings of the Mexican National Database and Community Survey Project which examines linkages between institutional characteristics in Mexico’s common property forestry sector and economic and environmental outcomes. Framing the Mexican agrarian community as a unit of analysis characterized by its history, individual members, resources, civic structure and property rights, we use institutional economic analysis to motivate project design and research on three aspects of Mexican community forestry governance: first, how communities have engaged forest resources to participate in forestry markets; second, how internal models of forestry management are reflect historical circumstances and practices, policy trends and managerial preferences that are independent of vertical integration levels; third, correlation among market participation, internal organization and performance outcomes such as conservation levels, wealth and income indicators and public and private goods investment. The project employs unique community-level survey data collected in Durango and Michoacan between 2005 and 2007 to summarize basic statistics to describe the sector from the point of view of the project’s objectives. Preliminary results reveal an inverse relationship between integration into production chains and material wealth measures, no correlation between internal governance models and vertical integration, and significant regional variation in institutional characteristics. The emerging profile shows continually evolving and varied common property institutions and questions “one-size-fits-all” business models, pointing to the need for more specific understandings of the community forestry sector. The lessons learned can be applied to address the future role of “community” in Mexican economic and environmental policy, and, on a larger scale, the meaning of community forestry management in sustainable development strategies.

description: The dependence of the vortex penetration and expulsion on the geometry of mesoscopic superconductors is reported. Hall magnetometry measurements were performed on a superconducting Al square and triangle. The stability of the vortex patterns imposed by the sample geometry is discussed. The field-temperature $H-T$ diagram has been reconstructed showing the transitions between states with different vorticity. We have found that the vortex penetration is only weakly affected by the vortex configuration inside the sample while the expulsion is strongly controlled by the stability of the vortex patterns. A qualitative explanation for this observation is given.

description: We describe a variety of intriguing mode-coupling effects which can occur in a confined Bose-Einstein condensed system at finite temperature. These arise from strong interactions between a condensate fluctuation and resonances of the thermal cloud yielding strongly non-linear behaviour. We show how these processes can be affected by altering the aspect ratio of the trap, thereby changing the relevant mode-matching conditions. We illustrate how direct driving of the thermal cloud can lead to significant shifts in the excitation spectrum for a number of modes and provide further experimental scenarios in which the dramatic behaviour observed for the $m=0$ mode at JILA (Jin {\it et al.} 1997) can be repeated. Our theoretical description is based on a successful second-order finite-temperature quantum field theory which includes the full coupled dynamics of the condensate and thermal cloud and all relevant finite-size effects.
A comparison of mixed multiscale finite element methods for multiphase transport in highly heterogeneous media

Subjects: subject: Numerical Analysis (math.NA)

description: In this paper, we systemically review and compare two mixed multiscale finite element methods (MMsFEM) for multiphase transport in highly heterogeneous media. In particular, we will consider the mixed multiscale finite element method using limited global information, simply denoted by MMsFEM, and the mixed generalized multiscale finite element method (MGMsFEM) with residual driven online multiscale basis functions. Both methods are under the framework of mixed multiscale finite element methods, where the pressure equation is solved in the coarse grid with carefully constructed multiscale basis functions for the velocity. The multiscale basis functions in both methods include local and global media information. In terms of MsFEM using limited global information, only one multiscale basis function is utilized in each local neighborhood while multiple basis are used in MGMsFEM. We will test and compare these two methods using the benchmark three-dimensional SPE10 model. A range of coarse grid sizes and different combinations of basis functions (offline and online) will be considered with CPU time reported for each case. In our numerical experiments, we observe good accuracy by the two above methods. Finally, we will discuss and compare the advantages and disadvantages of the two methods in terms of accuracy and computational costs.

Most of the recent trade agreements have contained some environmental provisions, ranging from a pledge to protect the environment to very extensive environmental requirements. These results appear to reflect a recognition that trade has environmental consequences and that trade agreements can be constructed to help mitigate such effects.
title: Essays in urban economics and international trade
Creators: name: Boeri, Filippo
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2019

description: This thesis consists of four independent chapters on urban economics and international trade. The first chapter analyses the effect of an improvement of information and communication technologies (ICT) on student performance. By exploiting a vast infrastructural program implemented in Italy, I study how the availability of high-internet speed affects student educational outcomes. On average, I find a positive effect on student performance in numeracy subjects. However, the policy outcome significantly depends on individual socio-economic backgrounds, with disadvantaged students mostly excluded from the benefits. As a result, the program increased the dispersion of student outcomes. The second chapter (co-authored) analyses a security policy aimed at tackling criminal organisations. The policy, consisting in the confiscation of mafia assets, is meant to eradicate the pervasive presence of the mafia organisations on the Italian territory and harm their business model and earnings. We investigate to what extent this policy is able to regenerate deprived areas by assessing its impact on the value of buildings located in the nearby of confiscated/re-allocated properties. Results show a positive effect of confiscation on housing prices, with the largest gains concentrated in the most deprived areas and where mafia organisations are more deeply rooted. Third and fourth chapter investigate between and within-industry differences in the spatial distribution of economic activities. The third chapter consists in a cross-country analysis of the economic geography of manufacturing and service plants. I compute continuous agglomeration and co-agglomeration indices using two comprehensive datasets, that cover the whole population of British and French establishments. The estimates are used to analyse in a common framework between- and with-industry variation in agglomeration patterns. The empirical strategy makes it possible to test some of the main predictions suggested by the literature. The fourth chapter, focussing on France only, investigates to what extent exogenous trade shocks are able to reshape the spatial distribution of manufacturing activities. Results unveil a positive effect of import penetration from emerging economies on firm spatial agglomeration.
Does providing small frequent meals improve the nutritional intake among elderly residents with dysphagia who live in extended care?
Creators: name: Taylor, Kelly
Publisher: name: University of British Columbia
Year: 2009

description: Dysphagia, which is common among the elderly population, is a disorder of the swallowing mechanism that interferes with a person's ability to safely swallow while eating. Malnutrition and dehydration are common consequences of dysphagia and, if left untreated, can lead to mortality or acute conditions requiring medical intervention. Improving the nutritional intake of this population is challenging because of factors such as prolonged feeding time, diminished physical tolerance for eating, and palatability of the diet that can negatively influence the amount of food consumed at a meal. Research has suggested that smaller, more frequent meals may be of benefit for individuals with dysphagia for managing fatigue while eating. The purpose of this crossover study was to determine if serving five-meals versus the usual three-meals per day would result in improved energy intake among elders with dysphagia who lived in extended care. Thirty-one residents (71 to 96 years of age), with a diagnosis of dysphagia, were randomly assigned on their units into one of two groups. For the first study period, one group received three meals while the other group received the same amount of calories spread over five meals. In the second study period, four weeks later, the same menu was served but the meal pattern was reversed for the two groups. Food and fluid items consumed by participants during each four-day study period were weighed and energy intakes determined using Food Smart Nutrition Management software (version 5.0). Paired sample t-test analysis revealed that the average calories consumed were not significantly different for the two meal patterns (average calories for three-meal pattern: 1325 +/- 207 Kcal/day; average calories for five-meal pattern: 1342 +/- 177 Kcal/day P=0.565). Based on the study's findings, offering five feedings a day does not appear to improve intakes of this population when compared to three feedings. Dietitians involved in the care of this vulnerable group may need to consider other nutrition intervention strategies.

description: We provide a unified treatment of conformally soft Goldstone modes which arise when spin-one or spin-two conformal primary wavefunctions become pure gauge for certain integer values of the conformal dimension $Δ$. This effort lands us at the crossroads of two ongoing debates about what the appropriate conformal basis for celestial CFT is and what the asymptotic symmetry group of Einstein gravity at null infinity should be. Finite energy wavefunctions are captured by the principal continuous series $Δ\in 1+i\mathbb{R}$ and form a complete basis. We show that conformal primaries with analytically continued conformal dimension can be understood as certain contour integrals on the principal series. This clarifies how conformally soft Goldstone modes fit in but do not augment this basis. Conformally soft gravitons of dimension two and zero which are related by a shadow transform are shown to generate superrotations and non-meromorphic diffeomorphisms of the celestial sphere which we refer to as shadow superrotations. This dovetails the Virasoro and Diff(S$^2$) asymptotic symmetry proposals and puts on equal footing the discussion of their associated soft charges, which correspond to the stress tensor and its shadow in the two-dimensional celestial CFT.

description: In this work we present an accurate parameterization of the anti-neutrino flux produced by the isotopes 235U, 239Pu and 241Pu in nuclear reactors. We determine the coefficients of this parameterization, as well as their covariance matrix, by performing a fit to spectra inferred from experimentally measured beta spectra. Subsequently we show that flux shape uncertainties play only a minor role in the KamLAND experiment, however, we find that future reactor neutrino experiments to measure the mixing angle $θ_{13}$ are sensitive to the fine details of the reactor neutrino spectra. Finally, we investigate the possibility to determine the isotopic composition in nuclear reactors through an anti-neutrino measurement. We find that with a 3 month exposure of a one ton detector the isotope fractions and the thermal reactor power can be determined at a few percent accuracy, which may open the possibility of an application for safeguard or non-proliferation objectives.

description: We study how two magnetic impurities embedded in a solid can be entangled by an injected electron scattering between them and by subsequent measurement of the electron's state. We start by investigating an ideal case where only the electronic spin interacts successively through the same unitary operation with the spins of the two impurities. In this case, high (but not maximal) entanglement can be generated with a significant success probability. We then consider a more realistic description which includes both the forward and back scattering amplitudes. In this scenario, we obtain the entanglement between the impurities as a function of the interaction strength of the electron-impurity coupling. We find that our scheme allows us to entangle the impurities maximally with a significant probability.

description: One of the recently established paradigms in condensed matter physics is examining a system's behaviour in artificially constructed potentials, giving insight into physical phenomena of quantum fluids in hard-to-reach settings. A prominent example is the matter-wave scatterer lattice, also known as the barrier lattice or repulsive Dirac comb. There, high energy matter waves undergo transmission and reflection through narrow width barriers leading to stringent phase matching conditions with subsequent lattice band formation. It is one of the most well taught system in quantum mechanics but its realisation for macroscopic matter-wave fluids has remained elusive, in contrast to evanescently coupled lattice sites or waveguides. Here, we implement and study a system of exciton-polariton condensates in a non-Hermitian Lieb lattice of scatterer potentials by optically injecting incoherent exciton clouds which both emit, and interact with traveling polariton waves. By fine tuning the lattice parameters, we reveal a nonequilibrium phase transition between two distinct regimes of polariton condensation: a scatterer lattice of gain guided polaritons condensing on the lattice potential maxima, and trapped polaritons condensing in the lattice potential minima. The transition is characterised by multimodal condensation due to gain competition between the two regimes. Energy tomography on the polariton emission enables us to measure the intricate band structure of the optically induced lattices. Our results pave the way towards unexplored physics of non-Hermitian fluids in non-stationary mixtures of confined and freely expanding waves.

The background cosmological model is a $Λ$-dominated, low-$Ω_b$ Friedmann model with no Cold Dark Matter. We include thermal processes and non-equilibrium chemical evolution of the collapsing gas. We find that under these assumptions the first low-mass objects ($M \le 3\times 10^4 M_{\odot}$) may collapse already for $z\sim 30$, which is in quite good agreement with the recent WMAP results. A lower value of $a_0$ would lead to much slower collapse of such objects.

description: The properties of hydrogen-helium mixtures at high pressure are crucial to address important questions about the interior of Giant planets e.g. whether Jupiter has a rocky core and did it emerge via core accretion? Using path integral Monte Carlo simulations, we study the properties of these mixtures as a function of temperature, density and composition. The equation of state is calculated and compared to chemical models. We probe the accuracy of the ideal mixing approximation commonly used in such models. Finally, we discuss the structure of the liquid in terms of pair correlation functions.

description: Firstly, connotation of fruit industrialization is introduced, pointing out that fruit leading enterprise is an important vector of the operation of fruit industrialization, as well as the economic entity for the market exploitation, production and processing, and service offering of fruit industry. Secondly, advantages and disadvantages of the three typical interest sharing modes during fruit industrialization are analyzed from the perspective of benefit sharing. In the organizational mode of “leading enterprise + fruit farmer” in contractual relationship, fruit enterprise plays a major role and is at a dominant position in the negotiation; while fruit farmer is at a relatively weak position, which seriously frustrated the enthusiasm of fruit farmers. In the organizational mode of “specialized market + fruit farmer” in market transaction relationship, due to the restriction of certain factors, few agricultural enterprises participate in this mode; while fruit farmers are at a relatively weak position. Therefore, this mode can hardly promote the development of industrialization. In the organizational mode of “specialized agricultural association or cooperative + fruit farmer” in cooperative organization pattern, specialized association or cooperative protects the interests of fruit farmers, but neglects the interests of fruit enterprises. Finally, the vertical——horizontal integrated mode is put forward based on the development experience of the world and the actual situation of China, so as to provide guidance and reference for the fruit industrialization in China.

description: The storage capacity of the extremely diluted Hopfield Model is studied by using Monte Carlo techniques. In this work, instead of diluting the synapses according to a given distribution, the dilution of the synapses is obtained systematically by retaining only the synapses with dominant contributions. It is observed that by using the prescribed dilution method the critical storage capacity of the system increases with decreasing number of synapses per neuron reaching almost the value obtained from mean-field calculations. It is also shown that the increase of the storage capacity of the diluted system depends on the storage capacity of the fully connected Hopfield Model and the fraction of the diluted synapses.

description: Supraparticles are coordinated assemblies of discrete nanoscale building blocks into complex and hierarchical colloidal superstructures. Holistic optical responses in such assemblies are not observed in an individual building block or in their bulk counterparts. Furthermore, subwavelength dimensions of the unit building blocks enable engraving optical metamaterials within the supraparticle, which thus far has been beyond the current pool of colloidal engineering. This can lead to effective optical features in a colloidal platform with unprecedented ability to tune the electromagnetic responses of these particles. Here, we introduce and demonstrate the nanophotonics of meta-shell supraparticle (MSP), an all dielectric colloidal superstructure having an optical nonlinear metamaterial shell conformed onto a spherical core. We show that the metamaterial shell facilitates engineering the Mie resonances in the MSP that enable significant enhancement of the second harmonic generation (SHG). We show several orders of magnitude enhancement of second-harmonic generation in an MSP compared to its building blocks. Furthermore, we show an absolute conversion efficiency as high as 10^-7 far from the damage threshold, setting a new benchmark for SHG with low-index colloids. The MSP provides pragmatic solutions for instantaneous wavelength conversions with colloidal platforms that are suitable for chemical and biological applications. Their engineerability and scalability promise a fertile ground for nonlinear nanophotonics in the colloidal platforms with structural and material diversity.

We study the constraints on the Z-quark couplings imposed by our measurement. We analyze an integrated luminosity of 72 pb-1 collected by the CDF II detector in proton anti-proton collisions at s**(1/2) = 1.96 TeV at the Fermilab Tevatron. A comparison of the uncorrected A_{FB} between data and Standard Model Monte Carlo gives good agreement with a chi^2/DOF of 15.7/15. The couplings measurements are also consistent with Standard Model predictions.

description: We derive a general criterion for determining the onset of superradiant phase transition in electronic bands coupled to a cavity field, with possibly electron-electron interactions. For longitudinal superradiance in 2D or genuine 1D systems, we prove that it is always prevented, thereby extending existing no-go theorems. Instead, a superradiant phase transition can occur to a nonuniform transverse cavity field and we give specific examples in non-interacting models, either through Fermi surface nesting or parabolic band touching. Investigating the resulting time-reversal symmetry breaking superradiant states, we find in the former case Fermi surface lifting down to four Dirac points on a square lattice model, with topologically protected zero-modes, and in the latter case topological bands with non-zero Chern number on an hexagonal lattice.

description: The existence of gravitational anomalies claimed by Alvarez-Gaume and Witten is examined critically. It is pointed out that they were unaware of the essential difference between T-product quantities and T*-product quantities. Field equations and, therefore, the Noether theorem are, in general, violated in the case of T*-product quantities, that is, those directly calculable from Feynman integrals. In the 2-dimensional case, it is explicitly confirmed that the energy-momentum tensor is strictly conserved if the above stated property of the T*-product quantities is correctly taken into account. The non-existence of gravitational anomalies is explicitly demonstrated for the BRS-formulated 2-dimensional quantum gravity in the Heisenberg picture.

Liquid motion induced by electrostatic deformation of fluidic interfaces
Creators: name: Aggarwal, Januk Swarup
Publisher: name: University of British Columbia

description: This thesis introduces a novel method for deforming fluidic interfaces while minimizing the friction and hysteresis typically associated with conventional electrowetting systems. The technique uses thin solid surfaces that are patterned so that the contact angle of a liquid drop placed on the surface depends on location. With an appropriate pattern, the contact line between the fluid interface and the solid surface is immobilized to a degree which in turn constrains the drop shape in useful ways. With suitable surfaces and liquids, the position of the contact line is stable for a range of drop shapes. The drop can be deformed by applying an inhomogeneous electric field to the fluid interface. Since the contact lines are stable, movement of the liquid in the drop is induced while no contact lines are formed or moved, thus minimizing friction and eliminating hysteresis. This technique is examined in the context of two different example applications; one is a potential reflective information display and the other is a fluidic pump for enhanced surface heat transfer. With the reflective display, the deformation moves a coloured liquid drop through a thin, reflective solid substrate. The apparent reflectivity is modulated by changing the amount of coloured liquid that is between the reflective solid and the viewer. In the fluidic pump, the induced flow is along the surface of a solid substrate, in order to transfer heat along the surface at a rate that substantially exceeds that of an equivalent copper plate. Initial prototypes for the two applications were designed, tested and compared to simple models. These results demonstrate the basic feasibility of such systems and suggest that further research in this area is warranted.

description: Dirac fermions in $2+1$ dimensions with dynamically generated anticommuting SO(3) antiferromagnetic (AFM) and Z$_2$ Kekulé valence-bond solid (KVBS) masses map onto a field theory with a topological $θ$-term. This term provides a mechanism for continuous phase transitions between different symmetry-broken states: topological defects of one phase carry the charge of the other and proliferate at the transition. The $θ$-term implies that a domain wall of the Z$_2$ KVBS order parameter harbors a spin-$1/2$ Heisenberg chain, as described by a $1+1$ dimensional SO(3) non-linear sigma model with $θ$-term at $θ= π$. Using pinning fields to stabilize the domain wall, we show that our auxiliary-field quantum Monte Carlo simulations indeed support the emergence of a spin-$1/2$ chain at the Z$_2$ topological defect. This concept can be generalized to higher dimensions where $2+1$ dimensional SO(4) or SO(5) theories with topological terms are realized at a domain wall.

description: We validate the baryonic Tully Fisher (BTF) relation by exploring the Tully Fish er (TF) and BTF properties of optically and HI-selected disk galaxies. The data includes galaxies from: Sakai et al. (2000) calibrator sample; McGaugh et al. (2000: MC2000) I-band sample; and 18 newly acquired HI-selected field dwarf galaxies observed with the ANU 2.3m telescope and the ATNF Parkes telescope from Gurovich's thesis sample (2005). As in MC2000, we re-cast the TF and BTF relations as relationships between baryo n mass and W_{20}. First we report some numerical errors in MC2000. Then, we c alculate weighted bi-variate linear fits to the data, and finally we compare the fits of the intrinsically fainter dwarfs with the brighter galaxies of Sakai et al. (2000). With regards to the local calibrator disk galaxies of Sakai et al. (2000), our results suggest that the BTF relation is indeed tighter than the T F relation and that the slopes of the BTF relations are statistically flatter th an the equivalent TF relations. Further, for the fainter galaxies which include the I-band MCG2000 and HI-selected galaxies of Gurovich's thesis sample, we calc ulate a break from a simple power law model because of what appears to be real c osmic scatter. Not withstanding this point, the BTF models are marginally better models than the equivalent TF ones with slightly smaller reduced chi^2.

description: Background: The 8 foot up & go test assesses the dynamic balance and agility in elderly people. Its reproducibility has been evaluated in American population, but it is unknown whether it would work similarly in a different population like the Colombian. Objective: To evaluate the test-retest reliability and agreement level of the 8 foot up & go test in a sample of older adults from Bucaramanga, Colombia. Materials and methods: An evaluation of diagnostic tests was done in 114 elderly individuals. In the analysis, we assessed the test-retest reliability of the 8 foot up & go test by the Intraclass Correlation Coefficient (ICC 2.1) with their respective confidence intervals at 95% (95% CI). The agreement level was established by the Bland-Altman method. Results: The test-retest reliability of the 8 foot up & go test was very good (ICC: 0.98; 95% CI: 0.98- 0.99). The agreement was good in females (mean difference [MD] = 0.04 seconds and limits of agreement [LA]: -1.27; 1.36 seconds), and in elderly institutionalized (MD = 0.04 seconds [LA]: -3.18; 3.27 seconds). Conclusion: The 8 foot up & go test has very good reliability and good agreement in Colombian local elderly population.

On the essential constants in Riemannian geometries

description: In the present work the problem of distinguishing between essential and spurious (i.e., absorbable) constants contained in a metric tensor field in a Riemannian geometry is considered. The contribution of the study is the presentation of a sufficient and necessary criterion, in terms of a covariant statement, which enables one to determine whether a constant is essential or not. It turns out that the problem of characterization is reduced to that of solving a system of partial differential equations of the first order. In any case, the metric tensor field is assumed to be smooth with respect to the constant to be tested. It should be stressed that the entire analysis is purely of local character.

description: El consumo de vino en España ha ido disminuyendo en los últimos años, cediendo parte de su mercado a otras bebidas. Esta circunstancia, unida a los cambios en las preferencias y en las pautas de consumo del producto, crea una difícil situación para las empresas del sector vinícola. Por tanto parece fundamental que las empresas vinícolas analicen su situación de cara a adoptar unas adecuadas estrategias empresariales que les permitan hacer frente a la situación actual y a un futuro que se plantea complicado. Este estudio se enmarca en Navarra, región situada en el Norte de España, en el extremo occidental de los Pirineos. Es una de las zonas vitivinícolas españolas más antiguas y gran parte de su producción vinícola se acoge a la Denominación de Origen Navarra. Siendo consciente de la difícil situación que atraviesa el Sector, el Consejo Regulador de la Denominación de Origen Navarra, ha visto en los jóvenes un mercado nuevo y fresco que puede potenciarse. En este contexto se plantea el presente trabajo, cuyo objetivo es el análisis de la situación actual del consumo de vino, prestando especial atención al análisis de los hábitos y preferencias del segmento joven de los consumidores. Por otro lado también se pretende situar el vino en relación al consumo joven de bebidas alternativas. La investigación se inicia con una revisión de literatura sobre las variables que afectan al consumo de vino, entre los que destacan la edad, sexo, nivel de estudios, etc. El estudio empírico se ha basado en una encuesta ad-hoc realizada en los núcleos poblacionales más grandes de Navarra con el objetivo de detectar dónde se encuentran los mayores problemas de este mercado además de las distintas actitudes que adoptan frente a éste cada uno de los segmentos de la población analizados. Una vez realizado el correspondiente análisis estadístico, los resultados conducen a conclusiones que pueden ser útiles para el futuro diseño de estrategias comerciales de las empresas oferentes del sector vinícola navarro.
