Values of limit periodic sequences and functions
Authors: Veselý Michal , Hasil Petr 
Published: May 2016

Abstract
We consider limit periodic sequences and functions with values in pseudometric spaces. We construct limit periodic sequences and functions with given values. For any totally bounded countable set, we find a limit periodic sequence which attains each value from this set periodically. A corresponding result concerning such a construction of limit periodic functions is proved as well. For any totally bounded countable set which is dense in itself, we construct a limit periodic bijective map from the integers into this set. As corollaries, we obtain new results about non-almost periodic solutions of almost periodic transformable difference systems.

We establish some new oscillation criteria and give sufficient conditions to insure that all solutions of quasi-linear neutral dynamic equation are oscillatory on time scale 𝕋.

On freely generated semigraph C
*-algebras
Authors: Burgstaller Bernhard 
Published: May 2016

Abstract
For special universal C*-algebras associated to k-semigraphs we present the universal representations of these algebras, prove a Cuntz–Krieger uniqueness theorem, and compute the K-theory. These C*-algebras seem to be the most universal Cuntz–Krieger like algebras naturally associated to k-semigraphs. For instance, the Toeplitz Cuntz algebra is a proper quotient of such an algebra.

Authors: Fathi Ahlam M. , Abdel-Hameed Salwa A. M. , Margha Fatma H. , Abdel Ghany Nabil A. 
Published: May 2016

Abstract
In this study, nanoscale crednerite (CuMnO2) was prepared in the system
xCuO–(70–x)MnO–30SiO2
, where x has values 10, 15, 20, 25 and 30, via melting
quenching glass-ceramic technique. The electrocatalytic activity of the oxygen evolution reaction (OER) on
CuMnO2 deposits has been studied in 1.0 M KOH (25 ℃) by means of cyclic
voltammetry, linear sweep voltammetry, chronoamperometric and electrochemical impedance techniques. The study has shown
that the catalytic activity had increased with the increase of Cu content in the electrode composition, where the
optimum improvement in the apparent electrode catalytic activity was obtained at the M30 electrode (with x = 30). At
E = 0.6 V versus Ag/AgCl, the apparent oxygen evolution current density observed at the M30
electrode is 4 times greater than that observed with M10 (x = 10). The order of the OER with respect to OH
–

concentration measured at low and high potentials is ∼ 1.0 and the roughness of the electrodes was decreased with
the increase of the Cu content.
Revised Atomistic Models of the Crystal Structure of C–S–H with high C/S Ratio

Published: May 2016

Abstract
The atomic structure of calcium-silicate-hydrate (C1.67–S–H
x
) has been studied. Atomistic
C–S–H models suggested in our previous study have been revised in order to perform a direct comparison of
energetic stability of the different structures. An extensive set of periodic structures of C–S–H with
variation of water content was created, and then optimized using molecular dynamics with reactive force field ReaxFF and
quantum chemical semiempirical method PM6. All models show organization of water molecules inside the structure of
C–S–H. The new geometries of C–S–H, reported in this paper, show lower relative energy with respect
to the geometries from the original definition of C–S–H models. Model that corresponds to calcium enriched
tobermorite structure has the lowest relative energy and the density closest to the experimental values.
Peptide Hydration Phenomena through a Combined Quantum Chemical and Bottom-Up Approach
Authors: Lanza Giuseppe , Chiacchio Maria Assunta 
Published: May 2016

Abstract
The M06-2X, TPSS, and B3PW91 density functionals and the classical ab initio MP2 method were used to study microsolvation
around the protonated trialanine, Ala3H+. All adopted electronic structure approaches show the formation of
wires or compact ring clusters of water molecules strongly bonded to peptidic polar groups through hydrogen bonds with
hydration energy ranging from − 93 to –66 kcal mol
–1. Independently from the adopted electronic structure
methods, explicit water molecules favor peptidic chain with the polyproline II (PPII) conformation, thus the electronic
energy stability order of the four unfolded conformers follows the sequence:
PPII-PPII > β-PPII ∼ PPII-β > β-β, while entropy favors the reversed order. The
delicate balance of electronic energy (or enthalpy) and entropy modulated by the temperature accounts for the change in
abundance of the PPII and β conformations experimentally observed. The proposed bottom-up approach has been
developed following the energetically dominant polar groups of peptide and water dipoles interactions. The intrapeptide
dipole decoupling, caused by the β → PPII transformation, and the consequent greater dipole coupling with water
molecules provide a rational base to explain the energy gain due to the explicit water coordination to PPII residues.
Voltage Dependence of a Neuromodulator-Activated Ionic Current
Authors: Gray Michael , Golowasch Jorge 
Published: May 2016

AbstractThe neuromodulatory inward current (IMI) generated by crabCancer borealisstomatogastric ganglion neurons is an inward current whose voltage dependence has been shown to be crucial in the activation of oscillatory activity of the pyloric network of this system. It has been previously shown thatIMIloses its voltage dependence in conditions of low extracellular calcium, but that this effect appears to be regulated by intracellular calmodulin. Voltage dependence is only rarely regulated by intracellular signaling mechanisms. Here we address the hypothesis that the voltage dependence ofIMIis mediated by intracellular signaling pathways activated by extracellular calcium. We demonstrate that calmodulin inhibitors and a ryanodine antagonist can reduceIMIvoltage dependence in normal Ca2+, but that, in conditions of low Ca2+, calmodulin activators do not restoreIMIvoltage dependence. Further, we show evidence that CaMKII altersIMIvoltage dependence. These results suggest that calmodulin is necessary but not sufficient forIMIvoltage dependence. We therefore hypothesize that the Ca2+/calmodulin requirement forIMIvoltage dependence is due to an active sensing of extracellular calcium by a GPCR family calcium-sensing receptor (CaSR) and that the reduction inIMIvoltage dependence by a calmodulin inhibitor is due to CaSR endocytosis. Supporting this, preincubation with an endocytosis inhibitor prevented W7 (N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide hydrochloride)-induced loss ofIMIvoltage dependence, and a CaSR antagonist reducedIMIvoltage dependence. Additionally, myosin light chain kinase, which is known to act downstream of the CaSR, seems to play a role in regulatingIMIvoltage dependence. Finally, a Gβγ-subunit inhibitor also affectsIMIvoltage dependence, in support of the hypothesis that this process is regulated by a G-protein-coupled CaSR.
Docencia universitaria saludable: Una metamorfosis impostergable
Authors: Castillo-Cedeño Ileana , Flores-Davis Luz Emilia , Miranda-Cervantes Giselle , Murillo-León Susana 
Published: May 2016

This article belongs to an interdisciplinary process developed at the National University of Abstract. This article arises from the research process of the Healthy Pedagogy project at the Center for Research and Teaching in Education (CIDE, by its acronym in Spanish) of the National University of Costa Rica (UNA, by its acronym in Spanish). The Center is well known as the country’s teacher training school. CIDE is structured in 5 academic units or departments, that attend the undergraduate and postgraduate education at different levels of the education system. The research recovers the issue of health, as a crucial element of social and educational praxis. The Center relies on pedagogy as a science that supports the welfare of life in an holistic dimension. This is an interdisciplinary study that emerges from one of the objectives of the research project: identify healthy educational experiences in CIDE by applying a semi-structured questionnaire to 19 teachers from the 5 academic units. An integrated multimodal approach is used, quantitative and qualitative aspects are combined, because they offer an opportunity to explore, describe and contribute to the interpretation of what healthy means in light of the participants perceptions. The results suggest that there is a diversity of criteria regarding the meaning of healthy and how to generate appropiate personal and professional environments. This allows to identify the challenge, both for CIDE and the University, of approaching the health issue by articulating policies that promote healthy lifestyles inside and outside the classrooms in order to treat the educational community with social responsibility.
Apoyo a las necesidades e intereses pedagógicos docentes a partir del acompañamiento y escucha por parte de la docente investigadora
Authors: Ocampo-Hernández Stefany 
Published: May 2016

This process takes place under the qualitative paradigm through participatory action research (PAR) in a Care Network, located in Alajuela, Costa Rica. The main question that leads the reflection process is: how to support the teacher in finding answers to her educational needs, in the Maternal group dynamics, from my support and listening as a teacher-researcher? The answer comes through dialogue with the teacher and listening to her needs and pedagogical interests in response to group dynamics. All this as a result of reflection, analysis and systematization of various meetings with her. The participants in the study are; the teacher from Maternal group, a group of seven children, with ages between 2 to 3 years and me as a educator-researcher. The strategies used to collect the data were participant observation, use of diary entries and especially audio-recorded interviews. As main findings of the PAR: I found that the teacher started empowering her work based on the trust and listening to her needs by a companion that shared her concerns. Also, the group dynamic passes from a rigid structure to a ludic space, thanks to several intervention strategies from a comprehensive care and development perspective. The action research process developed reflects the importance of support for teachers in their educational institutions, since the creation of spaces for listening to their needs and interests allows all parties to work together thus acknowledging their needs. This support should incentivate, not destroy, the teaching work.
An Oral Discourse Perspective on Second Language Learning
Authors: Jazadi Iwan 
Published: May 2016

Teaching and learning to speak English using oral language data drawn from real life communication can be unique experiences for English teachers and students who usually rely on unauthentic written texts of a textbook. This small study focuses on a conversation involving the author and his native speaker counterpart. Entities of the conversation put under analysis and discussion include its register and generic structure, exchanges, prosodic features and communication strategies. The dialogic features of the text are presented in the data collection procedure and description section. The article is expected to provide a perspective for doing similar analysis with other oral data by teachers and advanced learners of English as a second or foreign language.

The Influence Of Ethical Leadership On Managerial Performance: Mediating Effects Of Mindfulness And Corporate Social Responsibility
Authors: Williams John J. , Seaman Alfred E. 
Published: May 2016

In a continuing world of corporate misdeeds and unscrupulous decision making, much of the management and academic literatures points to the incomplete knowledge of the consequences of ethics leadership. One of the bastions of ethics gatekeeping in the firm is the CFO but remarkably scant information can be found on their perceptions concerning ethics leadership. This study addresses this void by examining mindfulness and corporate social responsibility (CSR) initiatives as new mediating linkages in comprehending the influence of ethics leadership on managerial performance. Findings reveal that ethical leadership is positively associated with CSR initiatives which, in turn, operate to enhance managerial performance. Simultaneously, ethical leadership manifests a significant positive relationship with mindfulness but, surprisingly, there is no corresponding relationship with managerial performance. Instead, mindfulness indirectly influences managerial performance through the intervening effects on CSR initiatives. These findings suggest that firms can acquire better managerial performance by focusing efforts on CSR strategies, bringing cognitive processes of mindfulness to bear on these actions, and grooming ethics leadership. In addition, the results offer researchers new relationships to model in the leadership domain.
