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.

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

Harmonic functions on metric graphs under the anti-Kirchhoff law

When does an infinite metric graph allow nonconstant bounded harmonic functions under the anti-Kirchhoff transition law? We give a complete answer to this question in the cases where Liouville’s theorem holds, for trees, for graphs with finitely many essential ramification nodes and for generalized lattices. It turns out that the occurrence of nonconstant bounded harmonic functions under the anti-Kirchhoff law differs strongly from the one under the classical continuity condition combined with the Kirchhoff incident flow law.Peer ReviewedPostprint (author's final draft

BRAIN COMPUTER INTERFACE - Application of an Adaptive Bi-stage Classifier based on RBF-HMM

Brain Computer Interface is an emerging technology that allows new output paths to communicate the users intentions without the use of normal output paths, such as muscles or nerves. In order to obtain their objective, BCI devices make use of classifiers which translate inputs from the users brain signals into commands for external devices. This paper describes an adaptive bi-stage classifier. The first stage is based on Radial Basis Function neural networks, which provides sequences of pre-assignations to the second stage, that it is based on three different Hidden Markov Models, each one trained with pre-assignation sequences from the cognitive activities between classifying. The segment of EEG signal is assigned to the HMMwith the highest probability of generating the pre-assignation sequence. The algorithm is tested with real samples of electroencephalografic signal, from five healthy volunteers using the cross-validation method. The results allow to conclude that it is possible to implement this algorithm in an on-line BCI device. The results also shown the huge dependency of the percentage of the correct classification from the user and the setup parameters of the classifier

Seasonal concentration of cruise tourism in the Mediterranean

This research delves into analyzing the seasonality of cruise tourism in the Mediterranean by using the decomposition of the Gini index, used in the field of cruise tourism for the first time in literature. This study specifically used the decomposition to evaluate the contribution degree of each port to the global seasonal concentration of each Mediterranean region. Moreover, a cluster analysis technique (bootstrapped bagged clustering) was applied to classify the ports into homogeneous groups according to their seasonal patterns given the significant heterogeneity revealed in the major regions of the Mediterranean. The methodology applied can serve as a control and monitoring tool for measuring seasonal concentration levels in cruise tourism, allowing for policies against seasonality to be tailored in the cruise tourism segment.Universidad de Málaga.

Determinants of technology adoption in the retail trade industry - the case of SMEs in Spain

This paper analyzes the determinants of small and medium-sized enterprises’ technology adoption in the retail trade industry. From the theoretical perspective, two types of influential factors are differentiated in this respect: the personal characteristics of the manager/business owner and the business’s organizational characteristics. The empirical analysis is based on a survey of 268 small and medium-sized enterprises in the Spanish retail trade sector. A logistic regression specification is used as an econometric method. The results indicate that both the acquisition of new technical and electronic equipment and the obtaining of new software are affected by the two types of determinants previously pointed out. The manager/business owner’s entrepreneurial motivation and educational background have significant influences on technology adoption in this type of companies. Furthermore, being part of a business group, carrying out training activities for the employees and inter-firm cooperation also positively influence technology adoption in the retail trade industry

Improving the Measurement of Human Development

We propose a new Human Development Index that involves a number of changes with respect to the present one, even though it keeps the basic structure of the index (namely, preserving “health”, “education” and “material wellbeing” as the three basic dimensions of human development). The first change refers to the substitution of the arithmetic mean by the geometric mean, as a way of aggregating the different dimensions in a more sensible way. The second one leads to the introduction of distributive considerations in the evaluation of material wellbeing. The last change consists of the introduction of new variables to approach health and education, looking for a higher sensitivity of the index with respect to the differences between countries. These new variables are specially indicated for the analysis of human development in highly developed countries. Besides the conceptual discussion, that includes a characterization of the chosen aggregation formula, we present a comparative analysis of this new index and the standard one, focusing on the OECD countries.Human Development, multiplicative indices, distributive concerns, highly developed countries, HDI
