Market Power and/or Efficiency: An Application to U.S. Food Processing

This article separates oligopoly-power and cost-efficiency effects of changes in industrial concentration and assesses their impact on output prices in 32 food-processing industries. Empirical results indicate that although concentration induces cost efficiency in one-third of the industries, oligopoly-power effects either dominate cost efficiency or reinforce inefficiency, resulting in higher output prices in most industries. The article also provides fresh econometric estimates of oligopoly power and economies of size for the industries in question.industrial concentration, economies of scale, industrial organization, oligopoly power, food processing, Agribusiness, Industrial Organization, Productivity Analysis, L00, L11, L13, L66,

Thickness of the buccal bone wall and root angulation in the maxilla and mandible: an approach to cone beam computed tomography

Background: The objective of this paper is to anatomically describe the bone morphology in the maxillary and mandibular tooth areas, which might help in planning post-extraction implants. Methods: CBCT images (Planmeca ProMax 3D) of 403 teeth (208 upper teeth and 195 lower teeth) were obtained from 49 patients referred to the Dental School of Seville from January to December 2014. The thickness of the facial wall was measured at the crest, point A, 4mm below, point B, and at the apex, point C. The second parameter was the angle formed between the dental axis and the axis of the basal bone. Results: A total of 403 teeth were measured. In the maxilla, 89.4% of incisors, 93.94% of canines, 78% of premolars and 70.5% of molars had a buccal bone wall thickness less than the ideal 2mm. In the mandible, 73.5% of incisors, 49% of canines, 64% of premolars and 53% of molars had <1mm buccal bone thickness as measured at point B. The mean angulation in the maxilla was 11.67±6.37° for incisors, 16.88±7.93° for canines, 13.93±8.6° for premolars, and 9.89±4.8° for molars. In the mandible, the mean values were 10.63±8.76° for incisors, 10.98±7.36° for canines, 10.54±5.82° for premolars and 16.19±11.22° for molars. Conclusions: The high incidence of a buccal wall thickness of less than 2mm in over 80% of the assessed sites indicates the need for additional regeneration procedures, and several locations may also require custom abutments to solve the angulation problems for screw-retained crowns

Scalar model of flocking dynamics on complex social networks

We investigate the effects of long-range social interactions in flocking dynamics by studying the dynamics of a scalar model of collective motion embedded in a complex network representing a pattern of social interactions, as observed in several social species. In this scalar model we find a phenomenology analogous to that observed in the classic Vicsek model: In networks with low heterogeneity, a phase transition separates an ordered from a disordered phase. At high levels of heterogeneity, instead, the transition is suppressed, and the system is always ordered. This observation is backed up analytically by the solution of a modified scalar model within an heterogeneous mean-field approximation. Our work extends the understanding of the effects of social interactions in flocking dynamics and opens the path to the analytical study of more complex topologies of social ties.Postprint (published version

Learning in the navigational space: Age differences in a short-term memory for objects task Learning and Individual Differences

Age differences during development in visuospatial short-termmemory (VSTM) in navigation have not been sufficiently proven. The performance of typically developing children from five age groups (from 5 to 9 years old) and one group of young adults (from 25 to 30 years old) was studied in an Augmented Reality navigational VSTM task that involved remembering the location of objects presented in increasing span lengths. The main results showed that navigational VSTM has not fully developed at the age of 9. The measures of performance significantly improved between ages 8 and 9. The overall performance on our navigational task was not influenced by gender, but therewas a slight advantage for maleswhen the difficulty of the task increased regarding the performance accuracy and the errors committed. The Augmented Reality task correlated with traditional spatial tests. Possible cognitive, biological, and methodological explanations for the findings are discussed.This work was funded mainly by the Spanish Ministry of Economy and Competitiveness (MINECO) through the CHILDMNEMOS project (TIN2012-37381-C02-01) and confinanced by the European Regional Development Fund (FEDER).

Wayfinding Strategy and Gender - Testing the Mediating Effects of Wayfinding Experience, Personality and Emotions

Background: Individual differences have been seen to play a key role in spatial orientation. Gender implications have been previously described but little is known about how other variables, such as wayfinding anxiety, emotional difficulties and wayfinding experience can mediate this relationship. Methods: A group of 269 participants were involved in this study and completed questionnaires on their self-reported allocentric orientation strategy, wayfinding experience and satisfaction with the ability for wayfinding. Emotional outcomes were also investigated: spatial and trait anxiety, neuroticism, difficulties in emotion regulation, and personal safety. First, a principal component analysis was conducted and the studied variables were grouped into four components: outdoor wayfinding experience, wayfinding-related fear, emotional difficulties, and effective wayfinding skill. Afterwards, structural equation modelling was performed, using the MPLUS statistical program. Results: The results showed that gender constitutes a predictor for using an effective wayfinding skill and for feeling wayfinding-related fear. However, outdoor wayfinding experience, wayfinding-related fear and emotional difficulties did not mediate the relationship between effective wayfinding skill and gender. Conclusion: These results highlight the differential contribution of gender in the emotions that are experienced during spatial orientation and emotions that are related to other types of situations. The limitations, strengths and theoretical implications of the proposed model are discussed. Further investigation is needed in order to understand the role of emotions in spatial orientation

Web 2.0 en el proceso de enseñanza-aprendizaje. Aplicación a la enseñanza de Economía de la Empresa

El uso de Internet y su evolución acelerada en el tiempo no afecta exclusivamente a las empresas, sino que su ritmo viene marcado precisamente por los que se han de considerar nuevos productores de contenido en la Red. La Universidad no puede quedarse atrás en el uso de las TIC pero tampoco puede centrarse exclusivamente en plataformas de aprendizaje on-line de sofisticación elevada –OCW, Moodle, entre otros-, pero sin otorgar poder para modificar y generar contenidos a los usuarios. La Unidad Docente de Organización de Empresas del Departamento de Economía y Gestión Forestal de la Escuela Técnica Superior de Ingenieros de Montes de la Universidad Politécnica de Madrid propone el uso de plataformas Web 2.0 con el objeto de desarrollar competencias tradicionales y competencias 2.0. Estas plataformas tienen una gran acogida entre el alumnado, presentan utilidad tanto en el presente como en el futuro, y se puede utilizar como plataforma de Learning 2.0 de la Economía y Organización de Empresa

SLAM-based augmented reality for the assessment of short-Term spatial memory. A comparative study of visual versus tactile stimuli

The assessment of human spatial short-Term memory has mainly been performed using visual stimuli and less frequently using auditory stimuli. This paper presents a framework for the development of SLAM-based Augmented Reality applications for the assessment of spatial memory. An AR mobile application was developed for this type of assessment involving visual and tactile stimuli by using our framework. The task to be carried out with the AR application is divided into two phases: 1) a learning phase, in which participants physically walk around a room and have to remember the location of simple geometrical shapes; and 2) an evaluation phase, in which the participants are asked to recall the location of the shapes. A study for comparing the performance outcomes using visual and tactile stimuli was carried out. Fifty-Three participants performed the task using the two conditions (Tactile vs Visual), but with more than two months of difference (within-subject design). The number of shapes placed correctly was similar for both conditions. However, the group that used the tactile stimulus spent significantly more time completing the task and required significantly more attempts. The performance outcomes were independent of gender. Some significant correlations among variables related to the performance outcomes and other tests were found. The following significant correlations among variables related to the performance outcomes using visual stimuli and the participants subjective variables were also found: 1) the greater the number of correctly placed shapes, the greater the perceived competence; 2) the more attempts required, the less the perceived competence. We also found that perceived enjoyment was higher when a higher sense of presence was induced. Our results suggest that tactile stimuli are valid stimuli to exploit for the assessment of the ability to memorize spatial-Tactile associations, but that the ability to memorize spatial-visual associations is dominant. Our results also show that gender does not affect these types of memory tasks

The Opinions of European Companies on Corporate Social Responsibility and Its Relation to Innovation

In recent years there has been greater concern among companies to include responsible practicesin their goals. To achieve this aim, companies are beginning to manage economic, socialand environmental factors following socially responsible practices. Adopting a strategy of CorporateSocial Responsibility (CSR) may influence the different policies implemented by thecompany, one of which is that regarding innovation. In this study, we analyze the opinions of95 European companies, 42 of which form part of the Dow Jones Sustainability Index (DJSI)and 53 of which belong to the Dow Jones General Index (DJGI), concerning their CSR policy,the innovation carried out and the relation between the two concepts. Our results show that theDJSI companies, unlike those belonging to the DJGI, consider their CSR strategy to be a keyfactor in generating competitive advantages and profits. Moreover, the companies surveyedhave implemented innovations that are more incremental than radical, and these innovationpractices are found to be influenced by CSR strategies
