Abstract: El objetivo del presente trabajo fue evaluar sensorialmente el frijol común mejorado nutricionalmente (línea 38) y la variedad local (BAT 304) con productores y consumidores de dos comunidades de Holguín, Cuba. Se aplicó una encuesta exploratoria que determinó el alto consumo de los frijoles negros peque os, y las recetas: arroz con frijoles y potaje. Se seleccionó una muestra de 80 personas y se aplicaron tres pruebas entre marzo y junio del 2008: discriminatoria triangular, aceptabilidad y preferencia. Se encontró que 50 personas discriminaron correctamente entre las dos variedades (P<0,000001). No hubo diferencia significativa (P=0,9) en el porcentaje de participantes que clasificaron (en una escala de uno a cuatro) la consistencia del caldo, el sabor del potaje y la textura del grano entre las variedades; sin embargo, al calificar estas características con palabras, notaron una diferencia en consistencia y textura, mas no en el sabor del potaje elaborado con los dos tipos de frijol. Finalmente, siete evaluadores no indicaron una preferencia por el potaje elaborado con uno u otro tipo de frijol. De los 73 que sí expresaron una preferencia, no manifestaron diferencia estadísticamente importante (P=0,13). En conclusión, existió diferencia sensorial entre los frijoles, pero la preferencia fue similar, lo que sugiere una buena aceptación del consumidor por el frijol mejorado nutricionalmente.

Abstract: sensory evaluation of nutritionally improved beans (phaseolus vulgaris l.) in two cuban communities. the objective of this study was to evaluate the sensory characteristics of nutritionally improved common bean (line 38) and a local varie ty (bat 304) among bean producers and consumers in holguín, cuba. an exploratory questionnaire revealed that small-seeded black beans were the most consumed, and that rice and bean casserole were the main recipes. three sensory tests were applied to 80 individuals from march to june 2008: triangle discrimination, acceptability, and preference. fifty participants correctly discriminated between the two bean varieties (p<0.000001). there was no statistical difference (p=0.9, on a scale of 1 to 4) in the number of participants who classified broth consistency, the taste of the casserole, and the texture of the beans. however, when words were used to describe and score these characteristics, there was a difference between the bean varieties in consistency and texture, but not in broth taste. seven participants indicated no preference for the casserole prepared with either bean. of the remaining 73 that expressed a preference, there was no statistical difference (p=0.13) in the proportion who preferred any bean type. in conclusion, there are sensory differences between the nutritionally improved and locally consumed beans, but preference was similar, which suggests good consumer acceptance of nutritionally improved beans.

Abstract: the municipality of gibara has historically been known by its diversity in agricultural crops and particularly for its tradition in the cultivation of common bean (phaseolus vulgaris l.), an important leguminous staple in the diet of the local population. in this municipality, the town of velasco is known as cuba's granary. in this region producers have common bean losses during storage that in many occasions affect the economic revenues, its availability for consumption and the seed for planting, however, farmers do not know the causes that provoke those losses. it was for the above reasons that this study was conducted during the years 2003-2005 with the aim of estimating the damage and losses of the common bean in the traditional storage system in the municipality of gibara. to achieve the objective a methodological procedure proposed by (raboud et al., 1984), that fits to the domestic conditions was used. the results verified that the producers do not always use the appropriate practices for the handling of dry beans before being stored and not all have appropriate storage facilities to keep large volumes of grain without loosing its quality and quantity. the losses in storage can be up to 10% according to the storage conditions. the greatest damage and losses were caused by pathogenic fungus and insects, which were favoured by the combination of a high initial moisture content and temperature in the mass of the stored grain.
Meaning Making, Uncertainty Reduction, and Autobiographical Memory: A Replication and Reinterpretation of the TALE Questionnaire  [PDF]
Orlando J. Olivares
Psychology (PSYCH) , 2012, DOI: 10.4236/psych.2012.32028
Abstract: The present research was guided by two primary goals: 1) replicate the empirical structure of the Thinking about Life Experiences (TALE) questionnaire (Bluck, Alea, Habermas, & Rubin, 2005); and 2) explore how the functions of autobiographical memory may interact and support one another. Toward the second goal, it is suggested that the potential functions of autobiographical memory may be understood from an existential framework that is grounded by two principles: humans are driven by a need for meaning and meaning is found in relation to others and other things in the world. In this pursuit of meaning making, and a desire to know what to expect from the world, humans seek to create a coherent set of relations among the various existential elements in their lives (Heine, Proulx, & Vohs, 2006); accordingly, humans strive to reduce uncertainty about the world and their place in it. As such, the TALE was reinterpreted using a relational framework and a 28-item self-report measure was developed. Participants completed the TALE and the reinterpreted TALE (RTALE). The results provide some support for the 3-factor structure of the TALE. The proposed 4-factor structure of the RTALE was supported.
Valuation and Risk Assessment of a Portfolio of Variable Annuities: A Vector Autoregression Approach  [PDF]
Albina Orlando, Gary Parker
Journal of Mathematical Finance (JMF) , 2018, DOI: 10.4236/jmf.2018.82023
Abstract: This paper focuses on assessing the financial position of an insurer issuing a portfolio of Variable Annuities (VAs). Two multivariate models for the underlying and the interest rate are considered. The first model uses a single total rate of return for the basket of assets. The second one, jointly models the rates of return on the n assets in the basket. For simplicity, the insurer is assumed to be able to implement a static hedging programme to manage the risk. As an example, a homogeneous portfolio of VAs with GMDB and GMMB guarantees offering different investment opportunities to the policyholders is studied. The insurer can choose to rebalance the basket of assets regularly or not. Results for these two cases are presented.
Multidisciplinary Approach to a Recovery Plan of Historical Buildings

International Journal of Geophysics , 2011, DOI: 10.1155/2011/258043
Abstract: The paper emphasizes the advantages of employing multiple data techniques—geology, GPS, surveys of cracking, boreholes, seismic refraction and electrical resistivity tomography—to image the shallow stratigraphy and hypothesize the cause of instability of an urban area. The study is focused on the joint interpretation of the crack pattern, topographic monitoring and the features of the underground, to define the area affected by instability and the direction of ground motion with the objective to advance a hypothesis on the cause of the instability of the area and to depict the main features. Borehole stratigraphies for a univocal interpretation of the lithology of electrical and seismic data and electrical resistivity tomography to constrain the interpretation of the lateral velocity variations and thickness of seismic bedrock were used. The geophysical surveys reveals to be complementary in the depicting of underground features. The study is approached at small and medium scale.
Discrete Dynamics in Evolutionary Games

Discrete Dynamics in Nature and Society , 2012, DOI: 10.1155/2012/416789
Abstract: This paper furnishes a guide for the study of 2-dimensional evolutionary games in discrete time. Evolutionarily stable strategies are identified and nonlinear outcomes are explored. Besides the baseline payoffs of the established strategic interaction, the following elements are also vital to determine the dynamic outcome of a game: the initial fitness of each agent and the rule of motion that describes how individuals switch between strategies. In addition to the dynamic rule commonly used in evolutionary games, the replicator dynamics, we propose another rule, which acknowledges the role of expectations and sophisticates the replicator mechanism.
Racionalidade e escolha
Economia Global e Gest?o , 2007,
Abstract: the concept of rationality is one of the most debated and controversial notions that the economic science has to offer. the rational choice paradigm, which involves profit maximization and utility maximization behavior, may be questioned by an important number of studies that remind that the human choice process is not an error exempt process, that it does not ignore emotional factors and that it is not fulfilled outside a social context where interaction determines behavior. this text intends to characterize the way in which the economists work the notion of rational decision and applies some of their ideas to model the decision process. in particular, we build an exercise in which one considers the cognitive costs involved in the choice process and we make use of the discrete choice theory to exemplify how social interaction and stimuli like advertising determine consumption and utility trajectories.
Introduction: Referential descriptions: for and against
An??lisis filos?3fico , 2009,
Abstract: in this introduction i start by presenting and examining the main positions on the current debate concerning the semantic analysis of sentences containing definite descriptions. as is known, the debate in question has started off with russell's proposal (russell 1905), which has been initially criticized by both strawson (1950) and donnellan (1966). nowadays, waters are divided on this issue: some philosophers, representing the so-called univocality approach (kripke 1977, neale 1990), defend russell's original analysis, according to which all definite descriptions are quantificational expressions, whereas there are others who, following strawson′s and donnellan′s objections, consider that at least some descriptions are genuine singular terms and hence have referential meanings. among the defendants of the last approach, known as the ambiguity theory, we can find michael devitt (1981, 2004, 2007a, 2007b). in the second part of the paper, i then survey devitt's stance on some traditional arguments for the ambiguity theory -mainly, the arguments from misdescription, incompleteness, opacity, and anaphora-, and finally i consider the new ones that he has put forward in favor of the existence of referential descriptions: the argument from regularity, the one based on the comparison with demonstratives, and the argument based on weak rigidity.
General term rigidity as identity of designation: Some comments on Devitt's criticisms
An??lisis filos?3fico , 2009,
Abstract: in his paper "rigid application", michael devitt defends a particular version of the socalled 'essentialist conception' of rigidity for general terms, according to which rigid general terms are rigid appliers, namely, terms that if they apply to an object in any possible world then they apply to that object in every possible in which the object exists. devitt thinks that the thereby defined notion of rigidity makes for an adequate extension to general terms of kripke's notion, originally defined for singular ones, inasmuch as it serves to accomplish its same primary task: namely, "to distinguish terms that are not covered by a description theory from ones that are". he then criticizes the alternative conception of rigidity for general terms as identity of designation -specifically, laporte′s (2000) version- on the basis of its entanglement with some controversial metaphysical theses regarding the existence of universals -including a commitment to a selective realism concerning them. in this paper, i try to defend the identity of designation conception from his criticisms: with this aim, i propose a version different from laporte's, and claim it to be the best one to accomplish the above-mentioned primary semantic task, namely, the one of showing that some general terms, just like most ordinary names, cannot be accounted for in descriptive terms.
