Trophic and spatial complementarity on seed dispersal services by birds, wild mammals, and cattle in a Mediterranean woodland pasture
2021
Made available in DSpace on 2022-05-01T09:47:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-11-01 Università degli Studi di Palermo CYTED Ciencia y Tecnología para el Desarrollo Federación Española de Enfermedades Raras Most earth surfaces have undergone intensive land-use changes, creating habitat mosaics. Seed dispersal by animals is a crucial process in such mosaics, but community-wide studies comparing the functional complementarity and response to man-imposed habitat heterogeneity are rare. Here, we investigate the trophic and spatial seed dispersal networks underpinning a strong, woody vegetation expansion over a pastureland inside the largest forest remnant in western Sici…
Tourist choice, competitive tourism markets and the effect of a tourist tax on producers revenues
2022
We propose a model for the tourism sector assuming basically two markets, one for tourist services and the other for accommodation. These sub-markets are considered as separate but interrelated. The nature of the feedback is determined by a vertical complementarity between tourist services and lodging. We obtain the optimal solution of the tourist choice problem, the primary demand for tourist services and the derived demand for overnight stays. Then, we focus on the equilibrium outcomes assuming perfectly competitive tourism markets. We do not address the externalities caused by tourism activities. Consequently, we move away from efficiency by introducing a tax on overnight stays and insp…
Information assets: A typology of disclosed and non-disclosed information
2020
Abstract The debate surrounding the value of disclosed and non-disclosed information as a competitive element has stalled; it has not been possible to make a universal, precise claim as to their potential to generate competitive advantages. This empirical inconsistency can be explained in part by the heterogeneity of information assets, which can give rise to different information dimensions, each offering different potential for generating results depending on the degree to which they meet the conditions of complementarity and co-specialization with other resources. This article helps to move forward on this issue by presenting a theoretical construct of the concept “information assets" an…
The effect of cooperative infrastructure fees on high-speed rail and airline competition
2021
Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
‘E-TAP’ CURRICULUM FOR VIRTUE EDUCATION: A FIT ANALYSIS TO THE ‘SKOLA-2030’ CURRICULUM
2021
The virtue education curriculum ‘e-TAP’ is one of the recent efforts for improving character and virtue education at school in Latvia from preschool till grade nine. The objective of this research was to provide evidence regarding whether this curriculum is appropriate (‘fits’) to the Latvian context, in particular in reference to the Skola-2030 curriculum. Based on fit and feasibility theory, this work addressed the research question: “How does the treatment of virtues of the e-TAP curriculum fit to the treatment of virtues of the new Skola-2030 curriculum?”. The analysis used statistical descriptive frequency analysis of the virtues of each programme and comparative analysis between the t…
Do upscale restaurant owners use wine lists as a differentiation strategy?
2009
Abstract The present paper studies various criteria used by upscale restaurant owners to differentiate their restaurants and to define their positioning. In particular, we studied several wine list attributes. Through a cluster analysis and a correspondence factor analysis based on different objective wine list characteristics, we obtain two main differentiated profiles of restaurants according to the relative importance of their wine list in comparison with food menu: wine selection and complementarity. Upscale restaurants need to define their positioning strategy and elaborate their wine lists according to their strategy.
La investigación en Ciencias Laborales como una nueva dimensión del alumnado universitario. Una experiencia innovadora
2016
Profesorado del Grado de Relaciones Laborales y Recursos Humanos de la Universitat de València, se planteó en el curso 2013-2014, y dado que la titulación había pasado de Diplomatura a Grado, la necesidad de fomentar entre el alumnado la orientación investigadora, opción hasta dicho momento difícil de desarrollar. Por eso, a través del desarrollo del proyecto de innovación en dicho curso «Medios para la difusión de resultados de investigaciones en Ciencias Laborales», se creó una web (http://inveslab.blogs.uv.es/) en la que se recogieron los resultados obtenidos del mismo, un repositorio con los medios existentes para la difusión de los resultados de investigaciones en Ciencias Laborales. T…
Active macro-zone approach for incremental elastoplastic-contact analysis
2013
The symmetric boundary element method, based on the Galerkin hypotheses, has found an application in the nonlinear analysis of plasticity and in contact-detachment problems, but both dealt with separately. In this paper, we want to treat these complex phenomena together as a linear complementarity problem. A mixed variable multidomain approach is utilized in which the substructures are distinguished into macroelements, where elastic behavior is assumed, and bem-elements, where it is possible that plastic strains may occur. Elasticity equations are written for all the substructures, and regularity conditions in weighted (weak) form on the boundary sides and in the nodes (strong) between cont…
Can noncomplementarity of agency lead to successful problem solving? A case study on students’ interpersonal behaviors in mathematical problem-solvin…
2022
In student collaboration, purposeful peer interaction crucial for success on the task. Such collaboration requires adequate and purposeful student agency. Theoretically, the between-individual complementarity of agency be-haviors enhances purposeful interaction. However, the level of agency of group members can disrupt the collaborative interactions. We conducted a case study of collaborative mathematical problem solving, where one student's behaviors of noncomplementary agency characterized the group interaction. We examined the video recording of the group by continuous quantitative coding of students' agency behaviors and segmented the interaction process into four phases. We analyzed qu…
Trade-offs or Complements? : Balancing Diversified Stakeholder Expectations, Institutional Pressures, and Functional Demands in the Strategic Managem…
2019
While scholars and practitioners have warned that business schools are losing their edge in creating and disseminating relevant knowledge in the crosscurrent of environmental demands, the management and organization of higher education institutions (HEIs) have been described as “herding cats” and “organized anarchy”. The teaching–research nexus forms the cornerstone of academic organization and has a quintessential role in strategic management. However, despite the growing body of literature on HEIs’ teaching–research nexus, organization, and environmental changes, few studies have examined the interplay of the three. Therefore, this study combines two contingency-theory views to examine th…
