Visionary leadership in the administrative staff of the Guapan educational unit

The purpose of the present study lies in determining the visionary leadership manifest in the administrative staff of the Guapan Educational Unit, with the research taking the form of a positivist descriptive research study that will deepen the knowledge of the variable that concerns us: visionary leadership. Through the application of field designs, the information was obtained directly from interaction with the subjects, who made up a population of (62) subjects, among whom were (07) administrators and (55) educational professionals, with the sample consisting of 38 instructors. The instrument used was an 18-item multiple-choice questionnaire (Almost always, Sometimes and Almost never), which was validated by three experts, with a reliability of 0.97, which demonstrates that it is highly reliable. The consolidation of this research showed with its results that the administrative staff engages in visionary leadership in the Guapan Educational Unit. The opinion of the instructional staff, however, shows just the opposite, judging that the administrators show weakness in visionary leadership. For this reason, guidelines are offered to the administrators of the state-funded private school located in the Cañar province, Azogues district, Guapan parishPeer Reviewe

Notes on the Suboptimality Result of J. D. Geanakoplos and H. M. Polemarchakis (1986)

J. D. Geanakoplos and H. M. Polemarchakis (1986) prove the generic constrained suboptimality of equilibrium allocations in two period economies with incomplete markets. They perturb asset prices at equilibrium when the degree of market incompleteness equals one. Since prices do not parameterize the economy, a generic result cannot be obtained in such a way. These notes provide a detailed version of their proof in which utilities and endowments are perturbed.incomplete asset markets constrained suboptimality, transversality theory.

Redescription of Hemileius suramericanus (Acari, Oribatida, Scheloribatidae) with comments about Neotropical congeneric species

This paper represents the first redescription of Hemileius suramericanus (Hammer, 1958) (Oribatida, Scheloribatidae). Morphological and chaetotactic details are added to original Hammer's description. The species is compared with others Neotropical species of Hemileius and two new synonyms, H. laticlava and H. confundatus sensu Hammer, are proposed.Fil: Fredes, Natalia.

Shape basis interpretation for monocular deformable 3D reconstruction

We first use the initial frames of a monocular video to recover a rest shape, used later to compute a dissimilarity measure based on a distance matrix measurement. Spectral analysis is then applied to this matrix to obtain a reduced shape basis, that in contrast to existing approaches, can be physically interpreted. In turn, these pre-computed shape bases are used to linearly span the deformation of a wide variety of objects. We introduce the low-rank basis into a sequential approach to recover both camera motion and non-rigid shape from the monocular video, by simply optimizing the weights of the linear combination using bundle adjustment. Since the number of parameters to optimize per frame is relatively small, specially when physical priors are considered, our approach is fast and can potentially run in real time. Validation is done in a wide variety of real-world objects, undergoing both inextensible and extensible deformations. Our approach achieves remarkable robustness to artifacts such as noisy and missing measurements and shows an improved performance to competing methods.Peer ReviewedPostprint (author's final draft

Cp2TiCl/D2O/Mn, a formidable reagent for the deuteration of organic compounds

Cp2TiCl/D2O/Mn is an efficient combination, sustainable and cheap reagent that mediates the D-atom transfer from D2O to different functional groups and can contribute to the synthesis of new deuterated organic compounds under friendly experimental conditions and with great economic advantages.The Spanish MICINN (Project CTQ2015-70724-R)University of Sevill

THE UNIT ROOT PROPERTY WHEN MARKETS ARE SEQUENTIALLY INCOMPLETE

We consider pure exchange, one good OLG economies under stationary Markov uncertainty. It is known that when markets are sequentially complete, a stationary equilibrium at which the agents common matrix of intertemporal rates of substitution has a Perron root which is less than or equal to one is conditionally Pareto optimal (CPO). We assume that there exists a long-lived dividend paying asset and show that if dividends are strictly positive then the relation between the unit root condition and optimality holds even if markets are not sequentially complete. However, every equilibrium allocation is shown to be constrained CPO under the additional requirement that assets be freely disposable, which seems reasonable when dividends are positive and whose importance was pointed out by Santos and Woodford (1997) in their work on bubbles; this fact undermines the relation between the unit root property and optimality. The relation is less clear when dividends and asset prices are allowed to be negative in some states.Stochastic Overlapping Generations Models, IncompleteMarkets

R&D investment and financial contracting in spanish manufacturig firms

This paper presents a model in which a firm with a degree of R and D specialization raises external funds to develop a two-period project that involves some non-verifiable returns (R and D-type of project). Taking into account a possible opportunistic behavior by the manager, we find out that the optimal firm's debt equity ratio is negatively related to the firm's degree of R and D specialization, its internal funds, and the output generated by the R and D project. Moreover, the expected R and D output of the firm is related negatively to the firm's leverage and positively to the firm's degree of R and D specialization as well as the amount of internal funds. The novelty of this work is to derive these results from strategic default consideration of the managers of firms specialized in R and D investments, as opposed to the standard collateral arguments concerning debt financing. This has a consequence of a lower growth of the firm's debt-equity ratio once we compare firms specialized on R and D investments with others non specialized in these activities. We confirm our main theoretical findings making use of a Spanish data set of manufacturing firms during the period 1990-94

Determinants of innovativeness in SMEs. disentangling core innovation and technology adoption capabilities

This paper studies innovativeness in SMEs from a set of innovation indicators at the firm level, capturing various types of innovation (product, process, organisational, and marketing innovations) and the level of innovativeness in these firm’s developments. The article identifies two separate dimensions in the innovativeness of Spanish SMEs, using factor analysis techniques. One dimension is associated with the capabilities for core/internal innovation and the other with the capabilities for the adoption of technology. The paper shows that significant differences exist in the personal and organisational factors that favour these two dimensions. The entrepreneur’s motivation, business planning, and cooperation in R&D activities constitute significant factors when considering the core dimension of a firm’s innovativeness, but have no effect on the firm’s capabilities for technology adoption. However, the use of external consultancy services seems to have no significant effect on the core dimension of the innovativeness of anSME, whereas it is a relevant factor for its technology adoption. Furthermore, it is shown that the entrepreneur’s education plays a more significant role in the core dimension of a firm’s innovativeness than in its capabilities for technology adoption. Depending on the policy objectives, these differences should lead to the application of specific policy approaches when an attempt to stimulate innovation in SMEs is made
