description: El objetivo de este trabajo es el desarrollo, con la participacion de los grupos de un colectivo. Esta experienca se apoya en una investigacion llevada a cabo con agricultores y responsables profesionales (Proyecto Aquae (4) en la cuenca hidrografica para evaluar el consumo de agua, las perdidas de nitratos de la zona, y de 2) simular escenarios para analizer posiblres mejoras en la gestion. Se han probado dos tipos de escenarios con el objectivo de ajustar el uso del agua a los columenes disponibles y de disminuir las perdidas de nitratos: en primer lugar una optimizacion del riego y de la fertilizacion, y despues una gestion de las rotaciones a escala de zona (cinco zones en las que se ha dividido la cuenca hidrografica), asi como a escala de la cuenca. El modelo permite evaluar, para distintos escenarios de gestion, el coste que supone para los productores agricolas el respecto de las normas establecidas sobre uso aqua y fertilizacion en funcion de la variabilidad climatica interanual...The aim of this study is to develop simplified tools and methods in collaboration with the participation of local stakeholders for facilitating collective decision-making. The project is based on a series of experiments carried out with farmers, environmental officers and researchers (Aquae proyect) on the Aveyron-Lere catchment area. Within this framework: 1) a model of the catchment was constructed in order to examine water consumption and nitrate losses in the area, and 2) scenarios were simulated so as to assess possible management improvement. Two types of scenarios were tested with the objective of limiting water use to available volumes and reducing nitrate losses: first, irrigation and fertilization optimization; after that crop rotation management at local scale (in the five zones defined in the catchment), as well as the scale of the whole basin. The model allows the evaluation, for the different management scenarios, the cost for the farmers of respecting current water and fertilization regulations, as a function of the inter-annual climatic variability.

description: This paper establishes suficient conditions for the orbital stability of one-parameter spatially periodic traveling-wave solutions for one-dimensional dispersive equations. Our method of proof combines known techniques with some new ideas. As a consequence of our result, we give several applications for well known dispersive equations. Extension of the theory to regularized equations is also established.

description: This article aims to study the National Programme for Strengthening Family Agriculture (Pronaf) in their credit lines for costing and investment, in order to investigate their relationships and interfaces with the family farm, using it for a study in Rio Grande do Sul (Middle High Uruguay microregion). The question to be answered is: what kind of building that is generating Pronaf with family farmers? To do this, it was used a methodology based on qualitative, using semi-structured interviews and underpinned by arguments with secondary data from various sources and research. It is concluded that the program has a dual logic. On the one hand, it is financing production activities usual for farmers, such as grain and agricultural commodities. On the other hand, there is a process of economic diversification of productive activities, small livestock, crops and basic food for household consumption.

description: Benfords law states that for scale- and base-invariant data sets covering a wide dynamic range, the distribution of the first significant digit is biased towards low values. This has been shown to be true for wildly different datasets, including financial, geographical, and atomic data. In astronomy, earlier work showed that Benfords law also holds for distances estimated as the inverse of parallaxes from the ESA Hipparcos mission. We investigate whether Benfords law still holds for the 1.3 billion parallaxes contained in the second data release of Gaia (Gaia DR2). In contrast to previous work, we also include negative parallaxes. We examine whether distance estimates computed using a Bayesian approach instead of parallax inversion still follow Benfords law. Lastly, we investigate the use of Benfords law as a validation tool for the zero-point of the Gaia parallaxes.

description: This note discusses the contradiction between β and σ- convergence tests of agricultural per capita GDP, which was recently presented by Spohr and Freitas (RESR, vol. 49, No. 02, p. 341-368, April / June 2011). While the first type of test supports the hypothesis of convergence, the σ- convergence test does not validate this hypothesis. It is argued that this contradiction probably arises from nonlinearities in the convergence process, which can characterize the formation of convergence clubs. The convergence test was done again in a more rigorous way, according to the methodology proposed by Caselli, Eesquivel and Lefort (1996) and, subsequently, the formation of convergence clubs is tested using the methodology proposed in Phillips and Sul (2007), which has the advantage of accommodating various types of heterogeneity. The formation of three convergence clubs is confirmed and these results try to clarify the contradiction previously reported.

description: A classification of farms in four types is proposed, according to the composition of the labour force employed: exclusively family farm; land reform settlement (“assentado”); family farm with hired labour; non-family farm. Exclusively family farms are run by the owner and employ exclusively family labour; land reform settlements are also mostly family-run units; mixed family farms are run by the owner and employ predominantly family labour, complemented by hired labour; non-family farms depend mostly on hired labour, with or without the help of the owner’s family. Aspects such as area, gross production value, productivity and revenues are analysed. One of the main results is that the family units are largely predominant in number (90% of the total) and employ 80% of the labour force in the agricultural sector, although they contribute with only 50% of the gross production, in virtue of lower productivity. Inequality in land distribution within the groups is extremely high, even among family farms. In Brazil, only 16% of the total inequality of land distribution is due to the inequality between the four categories of farms, while 84% originate from the inequality within groups.
On the irreducibility of the commuting variety of a symmetric pair associated to a parabolic subalgebra with abelian unipotent radical

description: In this paper, we study the commuting variety of symmetric pairs associated to parabolic subalgebras with abelian unipotent radical in a simple complex Lie algebra. By using the ``cascade'' construction of Kostant, we construct a Cartan subspace which in turn provides, in certain cases, useful information on the centralizers of non $\mathfrak{p}$-regular semisimple elements. In the case of the rank 2 symmetric pair $(\mathrm{so}_{p+2},\mathrm{so}_{p}\times \mathrm{so}_{2})$, $p\geq 2$, this allows us to apply induction, in view of previous results of the authors, and reduce the problem of the irreducibility of the commuting variety to the consideration of evenness of $\mathfrak{p}$-distinguished elements. Finally, via the correspondence of Kostant-Sekiguchi, we check that in this case, $\mathfrak{p}$-distinguished elements are indeed even, and consequently, the commuting variety is irreducible.

description: We present HST/WFC3 multiband imagery of N103B, the remnant of a Type Ia supernova in the Large Magellanic Cloud, as well as HST/COS ultraviolet spectroscopy of the brightest radiatively shocked region. The images show a wide range of morphology and relative emission-line intensities, from smooth Balmer-line dominated collisionless shocks due to the primary blast wave, to clumpy radiative shock filaments due to secondary shocks in density enhancements. The COS data show strong FUV line emission despite a moderately high extinction along this line of sight. We use the COS data with previous optical spectra to constrain the shock conditions and refine the abundance analysis, finding abundances typical of the local interstellar medium within the uncertainties. Under an assumption that the material being shocked was shed from the pre-supernova system, this finding places constraints on any significant enrichment in that material, and thus on the non-degenerate star in what was presumably a single-degenerate Type Ia supernova.

One the functions that could play an important role in the success of a CSR strategy is Human Resource Management (HRM). Yet it is not always clear in practice what is exactly the role of HRM in this context and how can HRM leverage its concepts and tools to support CSR strategies. On the other side how does CSR influence HRM itself? The aim of this study is to explore the relationship between the complex domain of Corporate Social Responsibility (CSR) and domain of Human Resource Management (HRM) in a company. That is to analyze and understand how CSR could influence HRM and vice versa how HRM contributes to CSR. In this thesis theoretical and practical understanding of this topic was achieved. Theoretical frameworks from literature that give a structured approach to CSR and HRM mutual influence were presented. These theoretical frameworks were applied in a case study on the CSR strategy of specific Company. Useful practical insights and recommendations were derived.

We show that in the strong-coupling regime, the system undergoes a first order transition between polaronic and trimer states. Our result suggests that the smooth crossover predicted in previous literature for a superfluid background is the consequence of Cooper pairing and is absent in a normal system.

Aufgrund von externen und internen Rahmenbedingungen wird die Verankerung von Diversitätsmanage-ment im österreichischen Fachhochschulsektor allerdings sehr unterschiedlich gehandhabt. Anhand von Expert*innen-Interviews wird die derzeitige Verankerung von Diversi-tätsmanagement an zehn multidisziplinären Fachhochschulen in Österreich erhoben und mit theoretischen Aspekten zu Diversität und Diversitätsmanagement verknüpft. Dabei werden verschiedene Zugänge zu Diversitätsmanagement, relevante Diversitätsdimensionen, interne und externe Rahmenbedingungen sowie Strategien für Diversitätsmanagement diskutiert. Aus dieser Statuserhebung werden Handlungsempfehlungen abgeleitet, wie strategi-sches Diversitätsmanagement an Fachhochschulen in Österreich nachhaltig verankert werden kann. Als grundlegende Erfolgsfaktoren werden dabei u. a. die Vorgabe von klaren Rahmen-bedingungen durch das Ministerium sowie eine Kombination aus bottom-up und top-down Strategien bei der Implementierung ausgemacht. In der konkreten Umsetzung sind die Ver-knüpfung von Diversitätsmanagement mit übergreifenden FH-Strategien sowie die bedarfs-orientierte Maßnahmenentwicklung zentral.
description: Strategically-planned diversity management may enable universities of applied scienc-es to meet both their moral obligation to create equal opportunities and to raise their competi-tiveness. However, due to internal and external factors, diversity management in Austrian universities of applied sciences is implemented very differently. Based on interviews with experts, data on the current state of diversity management at ten multidisciplinary Austrian universities of applied sciences are collected. These are linked to theoretical aspects of diversity and diversity management. Different approaches to diversity and diversity management, relevant dimensions of diversity, internal and external factors as well as strategies for diversity management are discussed. Consequently, recommendations are made on how strategic diversity management at multidisciplinary universities of applied sciences in Austria can be implemented sustainably. Factors relevant for it to be successful are the stipulation of clear basic parameters by the fed-eral authorities and a combination of bottom-up and top-down strategies during the imple-mentation process. Moreover, it is essential to integrate diversity management into the overall strategy and to gear appropriate measures to the needs of the respective university.

description: In 2011, 570 million reais were estimated to be used in the Crop Insurance Premium Subsidy (PSR), but only 253.4 million reais was allocated to the Program. In spite of this fact, it was possible to insure 5.6 million hectares with a liability of 7.3 billion reais. In this context, what should be the amount of resources to the PSR in order to cover the total amount of rural credit by the insurance market? The study presents a methodology to calculate, on average, what should be the budget of the PSR to insure the rural credit. The results suggest that the amount of resources should have been four times greater than the committed value. Moreover, the results were divided by state and crop. The PSR plays an important role to the development of the crop insurance in Brazil. However, two problems remain unsolved: the budget is far beyond the desirable and it has been restricted over the last three years. Therefore, there is an evident need for greater commitment from the Brazilian government to expand the resources of the PSR and direct it unique and fully to the PSR.

description: We model the effect of ground movement, based on empirical experience, on the transport properties of long neutron guides by ray-tracing simulations. Our results reproduce the large losses found by an earlier study for a simple model, while for a more realistic engineering model of guide mounting, we find the losses to be significantly smaller than earlier predicted. A detailed study of the guide for the cold neutron spectrometer BIFROST at the European Spallation Source shows that the loss is 7.0(5) % for wavelengths of 2.3-4.0 Å; the typical operational wavelength range of the instrument. This amount of loss does not call for mitigation by overillumination as suggested in the previous work. Our work serves to quantify the robustness of the transport properties of long neutron guides, in construction or planning at neutron facilities worldwide.

description: There are various different descriptions of Randall-Sundrum (RS) braneworlds. Here we present a unified view of the braneworld based on the gradient expansion approach. In the case of the single-brane model, we reveal the relation between the geometrical and the AdS/CFT approach. It turns out that the high energy and the Weyl term corrections found in the geometrical approach merge into the CFT matter correction found in the AdS/CFT approach. We also clarify the role of the radion in the two-brane system. It is shown that the radion transforms the Einstein theory with Weyl correction into the conformally coupled scalar-tensor theory where the radion plays the role of the scalar field.

To calculate the implied productivity index and the revealed sophistication, the method developed by Hausmann, Hwang and Rodrik (2005) was used, and to estimate the multiplier effect of the sophistication of the export basket to socioeconomic variables,the analysis of multiple regression was used. It is possible to say that the results confirm the hypothesis of the more sophisticated exports of the products of agribusiness of Southern Cone countries, the greater the effects of income growth and the multiplier effect (spillovers) for the economies of countries. However, ceteris paribus, to export agribusiness products implicitly associated with the higher income level constitutes an important strategy for accelerated growth, based on exports, and for achieving higher levels of welfare in the region.
The integration of tobacco reduction activities into the practice of acute care registered nurses : a mixed methods research project
Creators: name: Schultz, Annette Susan
Publisher: name: University of British Columbia
Year: 2009

description: In light of evidence linking tobacco use with various health issues, hospitals have become viable contexts for tobacco control strategies. Clinicians, in particular nurses, are being challenged to address patients' tobacco use by providing cessation interventions. Emerging evidence indicates that nurses support the idea of encouraging people to stop smoking, perceive an expectation upon them to address patients' tobacco use, and are reluctant to approach patients beyond assessing smoking status. Following this lead a concurrent mixed methods research project investigated acute care registered nurses' integration of tobacco reduction interventions. All nurses working at two hospitals in British Columbia, Canada were included in the project; hospitals were situated in regions that represented diversity in population smoking rates (19.6%- 31.2%). Two hundred and fourteen nurses (58% response rate) participated by completing a survey and ethnographic data collection was completed on the 16 adult inpatient wards, which included 135 hours of field observations, 114 brief conversations, document collection, and photographs of designated smoking areas. This first Canadian investigation of acute care nurses revealed similar views and practice activities related to tobacco use interventions. Beyond assessing smoking status, less than half of the respondents reported consistently advising, assisting, or arranging referrals for patients. Site comparisons demonstrated differences in available tobacco related resources, as well as reported practices of assisting and arranging referrals. Testing of a path model, which hypothesized causal mechanisms influencing nurses' practice, demonstrated nearly half of the variance in nurses' uptake of intervention activities was explained by the role attitude and four measures of perceived barriers. Indirect relationships were noted from perceived tobacco workplace climate factors and smoking status. The ethnographic profile of tobacco use and control in the study sites suggested systemic devaluing concerning support for patients' cessation efforts, a lack of awareness of addiction issues related to tobacco, and several burdens that patients' tobacco use brings to nurses' practice. Findings from each study were integrated into a multi-dimensional ecological behavior system, which emphasized the importance of moving beyond focusing on clinicians as a means to change practice. Rather health care institutions will be required to implement system-wide tobacco control strategies.

description: Die globale Klimaerwärmung und die Reduktion der großen Treibhausgasemissionen in die Atmosphäre zählen heutzutage zu den größten Herausforderungen des globalen Energiesystems. Viel diskutierte Lösungen sind etwa die Förderung erneuerbarer Energiequellen oder die Steigerung der Effizienz bestehender Energieumwandlungsprozesse, um eine drastische Reduzierung des Verbrauchs fossiler Brennstoffe zu erreichen. Eine Schlüsseltechnologie zur Effizienzsteigerung ist die Speicherung von Abwärme für die spätere Nutzung. Als konkretes Beispiel einer Technologie zur Speicherung von Wärme wird die thermochemische Energiespeicherung anhand des Reaktionssystems von wasserfreiem Kupfersulfat mit Ammoniak als Reaktivgas betrachtet. Dieses System erfüllt in besonderem Maße die vorgegebenen Kriterien der hohen Energiespeicherdichte, der Reversibilität der chemischen Reaktion und der Zyklenstabilität. Diese Arbeit beschäftigt sich mit der Erstellung und Untersuchung eines Geschäftsmodelles zur Kommerzialisierung solcher Energiespeichersysteme anhand eines konkreten Businessplanes. Im Vorfeld dazu wurden eine umfangreiche Literaturstudie und eine Umfrage mittels Fragebogen zu den technischen Gegebenheiten und zum angestrebten Markt durchgeführt.
description: Global warming and the reduction of large greenhouse gas emissions into the atmosphere are now among the greatest challenges of the global energy system. For example, much-discussed solutions include promoting renewable energy sources or increasing the efficiency of existing energy conversion processes in order to drastically reduce the consumption of fossil fuels. A key technology for increasing efficiency is the storage of waste heat for later use. As a concrete example of a heat storage technology, the thermochemical energy storage technology is considered using the reaction system of anhydrous copper sulfate with ammonia as the reactive gas. This system particularly meets the given criteria of high energy storage density, the reversibility of the chemical reaction and the cycle stability. This thesis deals with the creation and investigation of a business model for the commercialization of such energy storage systems based on a concrete business plan. In advance, an extensive literature study and a survey were carried out by means of questionnaires on the technical conditions and the desired market.

description: Based on the Industrial Economics theory, this study aimed to analyze the soybean processing industry structure, corporate conduct and performance in Brazil. Considering the relevant market of soybean processing industry, it was analyzed the concentration index of soybean processors with sales and strategies determinants of the plants location of major companies that process soybean (Bunge, Cargill, ADM and Louis Dreyfus), analyzing changes from 1990 to 2010. To analyze the sector performance in Brazil, matrix correlation and multiple regression method of weighted least squares statistical analyses were used. Overall, in Brazil, there is still an increase trend in the number of soybeans processing plants. However, in 2010, the number of non-operating plants was higher, showing that not all processors are fully using resources. It was found that the concentration of soybean processors is not limiting the performance of the sector, but the costs have not been fully transferred by soybean producers to prices.

description: The most elementary structures of turbulence, i.e., vortex tubes, are studied using velocity data obtained in a laboratory experiment for boundary layers with microscale Reynolds numbers 295-1258. We conduct conditional averaging for enhancements of a small-scale velocity increment and obtain the typical velocity profile for vortex tubes. Their radii are of the order of the Kolmogorov length. Their circulation velocities are of the order of the root-mean-square velocity fluctuation. We also obtain the distribution of the interval between successive enhancements of the velocity increment as the measure of the spatial distribution of vortex tubes. They tend to cluster together below about the integral length and more significantly below about the Taylor microscale. These properties are independent of the Reynolds number and are hence expected to be universal.

description: The quality is a complex issue that manifests significantly in Vale dos Vinhedos, the main producing area of fine wines in Brazil. Therefore, the study discusses the social construction of the quality of fine wines in Vale dos Vinhedos, microregion that was defined to begin a process of recognition of Geographical Indication. Increasingly, markets have been perceived as social constructions, in which the actors have the ability to create differentiated products.

Songs of ascents : a collaboration of singer, composer and ancient text
Creators: name: Harris, Raymond Stanley
Publisher: name: University of British Columbia
Year: 2009

description: Interaction of composer, text and performer is a significant and fertile facet of Western music. From the Troubadour poet-composer through the composer-singer teams of Jacopo Peri and Vittoria Archilei, Mozart and Catarina Cavalieri to the twentieth century's Britten and Pears, singers and composers have often demonstrated a significant collaborative relationship. The goal of this paper (lecture-recital) is to introduce the newly composed song-cycle Songs of Ascents as contemporary fruit of the collaboration between composer Larry Nickel and tenor, Ray Harris. The first chapter will survey the working relationships of two twentieth-century composer-tenor teams: Roger Quilter (1877-1953) and Gervase Elwes (1866-1921) and Benjamin Britten (1913-1976) and Peter Pears (1910-1986). These collaborative models will provide context for issues relating to text selection and setting, performance considerations and ultimately their contribution to the repertoire. Chapter two will discuss the work of Larry Nickel, placing this song cycle within the context of his development as a composer, particularly with respect to his vocal music. The author's work as tenor soloist, including previous work with Nickel will also be briefly presented. Chapter three constitutes the main body of this paper and analyzes the Psalm texts and Nickel's musical setting of eight of the fifteen Psalms of Ascents (Psalms 120-134). The paper concludes with suggestions for this cycle's future performance potential and encouragement for others to pursue such collaborative ventures.

description: The tau lepton lifetime has been measured with the e+e- -> tau+tau- events collected by the DELPHI detector at LEP in the years 1991-1995. Three different methods have been exploited, using both one-prong and three-prong tau decay channels. Two measurements have been made using events in which both taus decay to a single charged particle. Combining these measurements gave tau_tau (1 prong) = 291.8 +/- 2.3 (stat) +/- 1.5 (sys) fs. A third measurement using taus which decayed to three charged particles yielded tau_tau (3 prong) = 288.6 +/- 2.4 (stat) +/- 1.3 (sys) fs. These were combined with previous DELPHI results to measure the tau lifetime, using the full LEP1 data sample, to be tau_tau = 290.9 +/- 1.4 (stat) +/- 1.0 (sys) fs.

description: Ionospheric conductance is a crucial factor in regulating the closure of magnetospheric field-aligned currents through the ionosphere as Hall and Pedersen currents. Despite its importance in predictive investigations of the magnetosphere - ionosphere coupling, the estimation of ionospheric conductance in the auroral region is precarious in most global first-principles based models. This impreciseness in estimating the auroral conductance impedes both our understanding and predictive capabilities of the magnetosphere-ionosphere system during extreme space weather events. In this article, we address this concern, with the development of an advanced Conductance Model for Extreme Events (CMEE) that estimates the auroral conductance from field aligned current values. CMEE has been developed using nonlinear regression over a year's worth of one-minute resolution output from assimilative maps, specifically including times of extreme driving of the solar wind-magnetosphere-ionosphere system. The model also includes provisions to enhance the conductance in the aurora using additional adjustments to refine the auroral oval. CMEE has been incorporated within the Ridley Ionosphere Model (RIM) of the Space Weather Modeling Framework (SWMF) for usage in space weather simulations. This paper compares performance of CMEE against the existing conductance model in RIM, through a validation process for six space weather events. The performance analysis indicates overall improvement in the ionospheric feedback to ground-based space weather forecasts. Specifically, the model is able to improve the prediction of ionospheric currents which impact the simulated dB/dt and ΔB, resulting in substantial improvements in dB/dt predictive skill.

description: The European Union and Latvia have commited to reach ambitious goals in the development of power supply to decrease the reliance on imported energy resources and the influence of the power supply sector on climate changes . The target for the year 2020 is to achieve a renewable energy source share of 20% in the end consumption. The EU targets to reach 32% share of renewable energy in final consumption by year 2030, while Latvia targets 42% in the same time period. One way to achieve this is to encourage households to use low-power renewable energy sources by installing micro-generation equipment, thereby converting energy users into prosumers. Proper and efficient use of renewable energy sources by households contributes to long-term economic benefits by increasing the competitiveness of households while reducing CO2 emissions, increasing the share of renewable energy in overall consumption and stimulating investment in the sector. In order to stimulate the development of micro-generation and increase the share of renewable energy in the total amount, several EU countries, including Latvia, have introduced a Net Metering that is used to regulate payments for generated and consumed energy. The Net Metering is an instrument that fosters efficient use of energy and installation of low-capacity electricity-generating equipment at households. This system may be, and is, implemented in various ways. The adopted exact Net Metering regulations influence not only the profitability of the operation of prosumers but also the power system and the other energy consumers. For this reason, it is very important to set up a balanced Net Metering, which takes into account the possibilities and peculiarities of the power system in question as well as the interests of the community as a whole. The substantiation of such a system is the main goal of the present study. In order to achieve the set goal, the Master Thesis solves the following main tasks: -The current situation regarding the use of low-capacity renewable energy source technologies (solar and wind power plants) at households along with the development prospects of these technologies in Latvia has been assessed; -A review and an analysis of the Net Metering systems in use have been conducted; -For estimating the economic indicators, network models have been synthesized, with connected prosumers, and verified; -By using the models synthesized and the database collected, the profitability of using RES at various alternatives of net metering implementation has been assessed; -recommendations and suggestions have been developed regarding the development of normative acts regulating the Net Metering as well as for consumers and network operators.

description: Lagrangian contact supersymmetries (depending on derivatives of arbitrary order) are treated in very general setting. The cohomology of the variational bicomplex on an arbitrary graded manifold and the iterated cohomology of a generic nilpotent contact supersymmetry are computed. In particular, the first variational formula and conservation laws for Lagrangian systems on graded manifolds using contact supersymmetries are obtained.

description: En este studio se aplica una function de precios hedonicos al vino tinto DO de Castilla-La Mancha con el fin de medir la influencia de las variables vinculadas ak origen del vino, calidad enological, variedad de uva, cosecha, ano de fermentacion y tamano del productor sobre el precio final. De los resultados obtenidos, se desprende que el origen territorial del vino es la variable que en mayor medida afecta al precio final, siendo DO Mentrida y DO Jumilla los vinos con mayor impacto positive sobre el precio, meintras que DO Almansa y DO Manchuela definen el segment mas bajo. El tamano del productor result igualmente significativo, concluyendose que los vinos procedentes de las empresas mas pequenas influencian positivamente el precio debido a los mayors costs que acarrean sus process de produccion y el character exclusive de sus productos, al contrario que las empresas mas dimensionadas donde sus vinos aportan menos valor. In this study is applied a medonic price function to the red wine DO of Castilla-La Mancha in order to measure the influence of the attributes linked to the wine origin, quality, grape variety, grape vintage, grape fermentation and producer size on the retail price. As far the results obtained, the wine origin is concluded to be the variable that mostly affects the retail price, where both DO mentrida and DO Jumilla wines have the largest impact on the price; whereas both DO Almansa and DO Manchuela wines are regarded as the low-segment market. The producer size is also statistically significant thus it is concluded a positive impact on price of the wines from the smallest producers because of the higher costs that their production lines have to deal with as well as the exclusive nature of their products, unlike the largest companies where their wines reduce the price.
