Fashion designers and their business partners: Juggling creativity and commerce
Authors: Overdiek Anja
Published: May 2016

Dual and complementary leadership is common in certain parts of the cultural and creative industries, such as in theatres or architecture firms. It is also surfacing now and then in the international designer fashion sector. Formerly hidden behind the branded glamour of a creative leader, the collaboration between a designer and a managerial/commercial leader has recently become more visible. In some countries, studies even claim that dual leadership is a sustainable managerial model for designer fashion entrepreneurship. What does this kind of leadership entail and how can its dynamics be understood? Theoretically, dual leadership can be seen as a particular form of the ambidextrous top management team (TMT). In order to succeed, a fashion designer and his business partner must juggle quantifiable and efficiency-driven processes as well as intangible and creativity-driven ones. How do they do this? To map the empirical field, this article turns to the practices of designer/business partner ‘pairs’ in Dutch small- and medium-sized fashion companies (SMEs). In this context, characteristics and collaborative practices are surfacing which are subsequently compared to TMT research. Results suggest a collectivist perspective on creative leadership and allow for some recommendations for Dutch designer fashion businesses and for research in other fashion geographies.
Influência de ácido indolbutírico no enraizamento de estacas semilenhosas de Campomanesia aurea
Authors: Emer Aquélis Armiliato , Schafer Gilmar , Avrella Eduarda Demari , Delazeri Morgana , Veit Pedro Augusto , Fior Claudimar Sidnei
Published: May 2016

Campomanesia aurea (O. Berg) is a species native to southern Brazil, naturally occurring from the state of São Paulo to Rio Grande do Sul, and presenting a great ornamental potential. The objective was to verify the rooting of semihardwood cuttings of Campomanesia aurea using indolebutyric acid (IBA) doses. The cuttings were collected in the municipality of Barão do Triunfo, Rio Grande do Sul State, in December 2014. The cutting base was immersed in concentrations of zero (control), 2,000, 4,000, 6,000 and 8,000 mg L-1 of IBA, subsequently established in a carbonized rice husk substrate and placed in a protected environment with an intermittent misting system. At 111 days after installation, dead and rooted cuttings, leaf retention, callus formation, root volume, root and shoot dry matter were evaluated. The experimental design was completely randomized with four replications with 20 cuttings. Data were submitted to analysis of variance and regression. No statistical differences were found for any of the evaluations. An average rooting was observed in 28% of cuttings and callus formation was observed in 48% of cuttings. Root average volume per cutting was 0.15 mL, root dry mass was 0.01 g, and shoot dry mass was 0.28 g. There was a negative correlation between leaf retention and mortality of cuttings. It is concluded that the production of C. aurea by cutting is viable, and that there was no positive response to the application of IBA with the conditions under which the experiment was developed.
Encouraging Civic Knowledge and Engagement: Exploring Current Events Through a Psychological Lens
Authors: Van Camp Debbie , Baugh Stacey-Ann
Published: May 2016

Engagement with political, social and civil issues is a fundamental component of an educated population but civic knowledge and engagement are decreasing among adolescents and young adults. A Psychology in Current Events class sought to increase this engagement and key skills such as critical thinking. A pre-posttest comparison found that the class significantly increased students’ civic engagement, civic knowledge, multicultural sensitivity, applied thinking skills, as well as skills such as their ability to consider alternative viewpoints, appreciate diversity, monitor current events and think critically.

Published: May 2016

Der vorliegende Beitrag stellt ein Konzept zur Fahrbahngüteschätzung mittels autoregressiver Filterung an einem Zweiachs-Fahrzeug
vor. Für einen durch Kalman-Filterung gewonnenen Schätzwert der Unebenheitsanregung kann mittels autoregressiver Filterung die
spektrale Unebenheitsdichte und damit die aktuelle Fahrbahngüte gewonnen werden. Diese wird in das Kalman-Filter zurückgeführt, wodurch
jenes fahrbahnadaptiv wird und die Schätzgüte erhöht werden kann. Das Konzept wurde an einem Viertelfahrzeugprüfstand
realisiert. Hierzu werden Messungen aufgezeigt.

Authors: Sauer Andreas , Perschl Franz , Rottengruber Hermann
Published: May 2016

Um die steigende Komplexität von Hybridfahrzeugen zu beherrschen und deren Potential vollständig auszuschöpfen, ist eine
intelligente Betriebsstrategie notwendig. Die mathematische Optimierung solcher Strategien benötigt hohe Rechenleistung
und Kenntnis über die vorausliegende Strecke. Da beides nur eingeschränkt im Fahrzeug verfügbar ist, wird in diesem
Beitrag vorgeschlagen, die Mobilfunk-Verbindung moderner Fahrzeuge zu nutzen. Die Prädiktion auf Basis von aufgezeichneten
Fahrprofilen anderer Fahrzeuge, und die nachfolgende Optimierung der Betriebsstrategie werden auf stationären
Backend-Servern durchgeführt.
Control of a hydraulic hexapod for a Hardware-in-the-Loop axle test rig
Authors: Kohlstedt Andreas , Olma Simon , Flottmeier Sarah , Traphöner Phillip , Jäker Karl-Peter , Trächtler Ansgar
Published: May 2016

The present paper describes the controller design for a hydraulic hexapod which is used as an excitation unit for
a Hardware-in-the-Loop axle test rig. This includes a description of the plant model, the subordinate drive controllers, the sliding
mode state observer as well as the position control of the free hexapod. Measurements show the high dynamics of the
position-controlled hexapod. The concept is extended to a hybrid position/force control to be used during axle test maneuvers. Its
functionality is demonstrated by a measurement used for the identification of the axle kinematics.
Verbesserte Schätzung von Fahrdynamikgrößen durch Modellierung der Fahrwerks- und Lenkkinematik
Authors: Renninger Johannes , Trächtler Ansgar
Published: May 2016

Im Fokus dieses Beitrags steht die fahrzeugspezifische Modellerweiterung eines Fahrdynamikbeobachters im Bereich der
Fahrwerks- und Lenkkinematik sowie deren Einfluss auf die Schätzgüte. Die Notwendigkeit der Modellierung der Lenkkinematik
wird durch Analysen am Einspurmodell gezeigt. Vor dem Entwurfsprozess des Beobachters wird das Modell, das die Vertikal-
und Horizontaldynamik des Fahrzeugs umfasst, geeignet zerlegt. Die resultierenden Teilbeobachter werden als Kalman Filter
und Erweitertes Kalman Filter ausgelegt. Die erreichte Steigerung der Schätzgüte durch Hinzunahme der Fahrwerks- und
Lenkkinematik zeigt sich insbesondere in einer höheren Qualität der
Schwimmwinkelschätzung. Die erzielten Verbesserungen werden durch praktische Versuchsfahrten validiert.

Authors: Shi Guomin , Yang Lina , He Tao
Published: May 2016

A protocol is described for plant regeneration from protoplasts of Gentiana straminea Maxim. via somatic embryogenesis. Protoplasts were isolated from embryogenic calli in an enzyme solution composed of 2% Cellulase Onozuka R-10, 0.5% Macerozyme R-10, 0.5% Hemicellulase, and 0.5 M sorbitol with a yield of 3.0 × 106 protoplasts per gram of fresh weight. Liquid, solid-liquid double layer (sLD) and agar-pool (aPL) culture systems were used for protoplast culture. The aPL culture was the only method that produced embryogenic, regenerative calli. With aPL culture, the highest frequencies of protoplast cell division and colony formation were 39.6% and 16.9%, respectively, on MS medium supplemented with 2 mg/L 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.5 mg/L N6-benzylaminopurine (BA). Microcalli were transferred to solid MS medium containing a reduced concentration of 2,4-D (0.5 mg/L) to promote the formation of embryogenic calli. Somatic embryos developed into plantlets on MS medium supplemented with 2 mg/L BA at a rate of 43.7%.
Hydrogels based on collagen and fibrin – frontiers and applications
Authors: Schneider-Barthold Caroline , Baganz Sabrina , Wilhelmi Mathias , Scheper Thomas , Pepelanova Iliyana
Published: May 2016

Hydrogels are a versatile tool for a multitude of applications in biomedical research and clinical practice. Especially collagen and fibrin hydrogels are distinguished by their excellent biocompatibility, natural capacity for cell adhesion and low immunogenicity. In many ways, collagen and fibrin represent an ideal biomaterial, as they can serve as a scaffold for tissue regeneration and promote the migration of cells, as well as the ingrowth of tissues. On the other hand, pure collagen and fibrin materials are marked by poor mechanical properties and rapid degradation, which limits their use in practice. This paper will review methods of modification of natural collagen and fibrin materials to next-generation materials with enhanced stability. A special focus is placed on biomedical products from fibrin and collagen already on the market. In addition, recent research on the in vivo applications of collagen and fibrin-based materials will be showcased.
pH-responsive release of chlorhexidine from modified nanoporous silica nanoparticles for dental applications
Authors: Fullriede Hendrik , Abendroth Philipp , Ehlert Nina , Doll Katharina , Schäske Jörn , Winkel Andreas , Stumpp Sascha Nico , Stiesch Meike , Behrens Peter
Published: May 2016

A pH-sensitive stimulus-response system for controlled drug release was prepared by modifying nanoporous silica nanoparticles (NPSNPs) with poly(4-vinylpyridine) using a bismaleimide as linker. At physiological pH values, the polymer serves as gate keeper blocking the pore openings to prevent the release of cargo molecules. At acidic pH values as they can occur during a bacterial infection, the polymer strains become protonated and straighten up due to electrostatic repulsion. The pores are opened and the cargo is released. The drug chlorhexidine was loaded into the pores because of its excellent antibacterial properties and low tendency to form resistances. The release was performed in PBS and diluted hydrochloric acid, respectively. The results showed a considerably higher release in acidic media compared to neutral solvents. Reversibility of this pH-dependent release was established. In vitro tests proved good cytocompatibility of the prepared nanoparticles. Antibacterial activity tests with Streptococcus mutans and Staphylococcus aureus revealed promising perspectives of the release system for biofilm prevention. The developed polymer-modified silica nanoparticles can serve as an efficient controlled drug release system for long-term delivery in biomedical applications, such as in treatment of biofilm-associated infections, and could, for example, be used as medical implant coating or as components in dental composite materials.
On the importance of a genre-based approach in the teaching of English for Medical Purposes
Authors: León Pérez Isabel K. , Martín-Martín Pedro
Published: May 2016

In experimental disciplinary fields such as medicine, the writing up of a research paper in English may represent a major hurdle, especially for inexperienced writers and users of EAL (English as an Additional Language), mainly due to a lack of familiarity with international discourse conventions. Despite the efforts of many EAP (English for Academic Purposes) researchers and practitioners to provide support for medical PhD students and novice scholars by carrying out studies on research writing, specific courses with an explicit pedagogical approach to the teaching of academic genres are still scarce. Moreover, it often happens that the only possibility of receiving training in writing skills is in the pre-clinical years, when the students are not yet experienced language users and when they lack both the genre conventions and the specialized subject knowledge for such a demanding task. In this article, we offer our view of a genre-driven pedagogy and its practical applications in an EMP (English for Medical Purposes) classroom with the ultimate aim of helping students to publish their medical papers in international (English-language) journals. Our genre-based teaching approach consists in a prior discussion with students about the socio-cultural context in which a particular academic genre occurs. This process of discovery of the social circumstances that surround a specific genre can help them understand more readily its communicative purpose. We believe that a second stage should be the explicit teaching of functions and language structures of archetypal academic texts, initially in a highly controlled fashion, and later on a freer basis, but always using reference papers for illustration and comparison. If learners are more aware of the rhetorical strategies preferred by the members of their disciplinary communities, they may feel more confident as EAL writers about the rhetorical options they can choose depending on the context and type of audience they are addressing.
Learning terminology in order to become an active agent in the development of Basque biomedical registers
Authors: Unzalu Igone Zabala , Martin Egia Itziar San , Ayestaran Mikel Lersundi
Published: May 2016

The aim of this article is to describe some theoretical and methodological bases underpinning the design of the course Health Communication in Basque (HCB) at the University of the Basque Country (UPV/EHU). Based on some relevant theoretical tenets of the socioterminologic and communicative approaches to Terminology, the authors assume that terminology planning must be adapted to the sociolinguistic situation of each language. Moreover, the article claims that terminology planning for a language undergoing a normalization process must acknowledge the target situation of well-developed languages, in which terminology changes over time and varies according to communicative situations. Taking into account the sociolinguistic situation of Basque, the authors conclude that the most important goal of the HCB course should be to help students become active agents in the development and consolidation of Basque biomedical terminology. Thus, the most relevant learning objectives defined in the syllabus involve language awareness with regard to terminology variation: using term formation rules to create different kinds of denominative variants, actively thinking about the grammaticality and genuineness of different variants of terms, and managing terminological variation according to functional criteria.

Putting the plain into pain language in English for Medical Purposes: Learner inquiry into patients’ online descriptive accounts
Authors: Plastina Anna Franca
Published: May 2016

The need to teach medical students plain language for their future engagement in pain communication can no longer be underestimated. Pain education has traditionally neglected the teaching of pain language, yet patients’ descriptive accounts have been acknowledged as the standard in medical care. English for Medical Purposes (EMP) can make its contribution to tertiary pain education, especially at a time when the plain language paradigm is considered key for health literacy. This is not to say that teaching specialized language and plain language for specific purposes are mutually exclusive. Yet, developing EMP learners’ understanding of the use of authentic plain pain language is also crucial for their future professional practice. This study reports on a pedagogical experiment conducted with the aim of enhancing EMP learners’ understanding of the lexico-grammatical features of pain language in patients’ descriptive accounts and in the use of pain assessment tools. The experiment was framed by the Hallidayan lexico-grammatical model of pain. Following a data-driven learning approach, students compiled a small DIY corpus of accounts from online health support groups and exploited its direct use through corpus-based tasks. These were designed to facilitate learners’ understanding of the features of pain language and of patients’ use of pain descriptors related to those in the McGill Pain assessment tool currently employed in medical care. Learners further broadened their understanding of pain language in other contexts of use while taking notes to fulfil the designed tasks. These helped shed light on the pedagogical practice here proposed.
International medical graduates and the discursive patterns of patient-centred communication
Authors: Woodward-Kron Robyn
Published: May 2016

In many Western countries such as Australia, international medical graduates (IMGs) play a crucial role in meeting health workforce needs. For doctors for whom English is an additional language and who have received their medical education in non-Western settings, a challenge is the patient-centred approach to communication, which is well established in Western medical education as the optimal approach for safe and effective healthcare. It acknowledges the patient as an active participant in the healthcare interaction, and the importance of the psychosocial dimension of patient well-being. While there is a vast literature on doctor-patient discourse in the qualitative health literature, there is little in the medical education domain that systematically examines the linguistic patterns of doctors who are learning or are less familiar with patient-centred paradigms of communication. This article examines how IMG doctors manage patient-centred interviewing. The data are 15 video-taped 8-minute roleplay consultations of IMGs and simulated patients. Systemic functional linguistics and genre theory provided the theoretical framework and tools to analyse how the doctors realised the tasks of patient-centred communication as informed by the medical education literature, with a particular focus on the tasks of gathering information, providing information and decision-making. The findings suggest that the discourse patterns of doctor-patient communication demonstrated by the IMG doctors were
Failure Analysis Using Functional Model and Bayesian Network
Authors: Khalil Mohamed A. , Ahmad Arshad , Abdullah Tuan Amran T. , Al-shanini Ali
Published: May 2016

A class of functional model known as multilevel flow model (MFM) is used to represent a pilot scale heat exchanger system. MFM is effective in representing chemical process qualitatively through graphical representation, but lacks the ability to quantify the impact of successes or failures of process events, and is not able to quantitatively distinguish between steps in a goal and their contributions towards achieving the main goal. To address this issue, the MFM is converted into its equivalent fault tree (FT) model to accommodate logical sequence of events along with the needed quantifications. The FT model is then converted into Bayesian network (BN) model to facilitate updates of probabilities. Using Hugin 8.1 software, the BN model is simulated to investigate the response of the process when subjected to various faults. The results highlight the capability of the model in detecting process faults and in identifying the associated root causes, thus pointing to the potentials of the proposed strategy in modeling complex chemical processes for higher level functions in plant operations such as facilitating alarm system and fault diagnosis.
Translational radionanomedicine: a clinical perspective
Authors: Choi Hongyoon , Lee Yun-Sang , Hwang Do Won , Lee Dong Soo
Published: May 2016

Many nanomaterials were developed for the anticipated in vivo theranostic use exploiting their unique characteristics as a multifunctional platform. Nevertheless, only a few nanomaterials are under investigation for human use, most of which have not entered clinical trials yet. Radionanomedicine, a convergent discipline of radiotracer technology and use of nanomaterials in vivo, can facilitate clinical nanomedicine because of its advantages of radionuclide imaging and internal radiation therapy. In this review, we focuse on how radionanomedicine would impact profoundly on clinical translation of nanomaterial theranostics. Up-to-date advances and future challenges are critically reviewed regarding the issues of how to radiolabel and engineer radionanomaterials, in vivo behavior tracing of radionanomaterials and then the desired clinical radiation dosimetry. Radiolabeled extracellular vesicles were further discussed as endogenous nanomaterials radiolabeled for possible clinical use.
Standard and Colloquial Belgian Dutch pronouns of address: A variationist-interactional study of child-directed speech in dinner table interactions
Authors: Van De Mieroop Dorien , Zenner Eline , Marzo Stefania
Published: May 2016

This paper presents a corpus-based analysis of child-directed speech during Flemish family dinner table interactions. Specifically, we study parents’ style-shifts, that is, their alternation between Standard Dutch and Colloquial Belgian Dutch, a non-standard supraregional variant of Dutch, when interacting with their children. By integrating insights and methods from variationist and interactional sociolinguistics, we pay attention not only to macro-social categories (such as the age of the children), but also to the micro-social and pragmatic context (e. g. frames) of the style-shifts. The fact that this study focuses on a single case-study is a consequence of opting for this combination of course-grained quantitative analyses and fine-grained qualitative analyses. We rely on detailed transcriptions of three hours of recordings for one Flemish household with four children (age nine months, and four, five and seven years old). Our results reveal significant variation in the style-shifts of the mother (age 35) and the father (age 39) with respect to the four children. These results were interpreted against the background of comments made by the parents during a sociolinguistic interview that followed the recordings. Generally, our analyses allow us to provide a nuanced insight into the social meaning of the two language layers (Standard Dutch and Colloquial Belgian Dutch) as they are distributed across the speakers and situations in this family, thus revealing a link between the attested patterns of child-directed speech and the acquisition of sociolinguistic norms.

Weak solutions for generalized stationary Oldroyd-B fluid with a diffusive stress
Authors: Bousbih Hafedh , Majdoub Mohamed
Published: May 2016

This paper focuses on the analysis of the stationary case of incompressible viscoelastic generalized Oldroyd-B fluids derived in [2] by Bejaoui and Majdoub. The studied model is different from the classical Oldroyd-B fluid model in having a viscosity function which is shear-rate depending, and a diffusive stress added to the equation of the elastic part of the stress tensor.
Under some conditions on the viscosity stress tensor and for a large class of models, we prove the existence of weak solutions in both two-dimensional and three-dimensional bounded domains for shear-thickening flows.

Factors Associated with Alcoholic Beverages Consumption in Russia: A Discrete Choice Model
Authors: Yormirzoev Mirzobobo , Gabrielyan Gnel
Published: May 2016

Alcohol consumption in Russia remains a topic of extensive debate and investigation. In this article we attempt to explore and analyze some factors affecting vodka, beer, dry wine and champagne consumption in the country by utilizing the most recent household level dataset. We made use of logistical regression approach as a key empirical tool. Our findings highlight that there exist different trends and patterns in contemporary alcohol drinking behavior among respondents. This paper rejects the common stereotype that only vodka is a popular variety of alcohol beverage in Russia. In a model with dry wine and champagne most of explanatory variables remain statistically significant.
On the Relevance of Low-Mach-Number Asymptotics in Thermodynamics of Heterogeneous, Immiscible Mixtures
Authors: Varsakelis Christos , Papalexandris Miltiadis V.
Published: May 2016

A conundrum in non-equilibrium thermodynamics of heterogeneous mixtures with microstructure concerns the selection of thermodynamic currents and forces in the entropy production rate from the multitude of available options. The objective of this article is to demonstrate that the low-Mach-number approximation can narrow down this ambiguity. More specifically, by postulating that the post-constitutive equations are well behaved with respect to this perturbation analysis we assert that thermal non-equilibrium should be chosen as an independent force even if this requires the explicit manipulation of the entropy inequality. According to our analysis, alternative choices result in post-constitutive equations; the incompressible limit of which gives rise to questionable predictions.
Values of limit periodic sequences and functions
Authors: Veselý Michal , Hasil Petr
Published: May 2016

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.

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

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

The atomic structure of calcium-silicate-hydrate (C1.67–S–H

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

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

The 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.

The Medicine students need to increase their research skills. Therefore, there is a main goal to train the fifth year students in epidemiological analysis methods during educational activities in work hours. In the Tula Aguilera Health Area, the fifth year Medicine students conducted a control-case study, where they applied a 14 questions survey to 69 persons sick with infectious diarrhea during June to December 2013. The results were compared to those of 131 healthy persons. The survey collected demographic, environmental and lifestyle variables. For each factor found, odd ratios (OR) were determined and the behavior of the analyzed variables was compared in both groups with the logistic regression technique. The basic reproductive number (Ro) was determined considering its impact and a simulation was compared with the usual historical dispersion of those diseases. Among the results, the students were trained to gather information and to transfer data to Excel Worksheets to analyze causal relationships. The students, after analyzing, were able to establish that the surveyed population had a low risk perception, they were also able to establish and calculate differences between sick and healthy people; for instance, people who don’t cover solid wastes and become sick have nearly three times more risk (OR=2.81; IC 1.34-6.03), moreover the students were able to demonstrate the presence of environmental hazards. They found that the survey was reliable and became familiar with the usage of the basic reproductive number and derived simulations. We conclude that the designed training allowed the students to increase their skills during the educational practices at work regarding the learning by doing research methodology. The trainig strategy is valid, sustainable, updated and of great value in the Medicine students instruction.
El papel de las experiencias escolares preuniversitarias en la conformación de un proyecto de vida ligado a la educación superior en estudiantes con discapacidad
Authors: Cruz-Vadillo Rodolfo , Casillas-Alvarado Miguel Ángel
Published: May 2016

This article aims to approach the school experiences of 13 students with disabilities. It corresponds to a cross, synchronous and non experimental study, whose scope is mainly descriptive. The data collection was carried out through a semi-structured interview and transcribed from audio recordings to make a category analysis. The main results showed that in the case of students who were born with disabilities, the fact that an institution was inclusive turned out essential for them to have adequate transit through the educational system and thus become apt for higher education. The combination disability-inclusion-right to education-higher education is what this paper aimed to weave, trying to follow as thread or anchor, the previous school experiences of students with disabilities. We recognize that an adequate, inclusive, positive experience besides a subjective construction of the body and disability by family members, become important conditions to access schooling. Education is a right, therefore it can not be seen as an act of charity; it should be required as a quality practice.
Innovación en los procesos de enseñanza-aprendizaje: Un estudio de casos con la enseñanza justo a tiempo y la instrucción entre pares

Learning quality constitutes one of the main challenges faced by Higher Education, thus a student centered teaching and the development of educational innovations that use active methodologies have been promoted. This article aims to evaluate the impact of using Just-in-Time Teaching and Peer Instruction on the results of teaching a subject, of disciplinary character, in 17 students of a career on an initial teacher training belonging to Chile’s Council of Rectors. A pre and postest model was applied between August and December 2012. The analysis used descriptive techniques that allowed the characterization of the admission profile and inferentials to explain, statistically, the observed differences in the performance of the subjects. In terms of perception, a positive assessment of the relationship between students and the teacher in the classroom was observed, this stood out above the improvement in the handling of disciplinary content.
Relación teoría-práctica entre el campo de la formación inicial y el escenario del ejercicio profesional
Authors: Sánchez-Sánchez Gerardo Ignacio
Published: May 2016

This article, developed at the regional campus of a university, located 200 miles south from Santiago de Chile, shows how 185 students of preschool, elementary and middle education, experience and perceive the relationship theory-practice from their insertion in the school environment. The mixed approach adopted relies on an opinion questionnaire and a semi-structured interview administered in the tutoring spaces. The results show that 39% of the teaching students believe that theory and practice are opposite realities, while 31% say that the theory depends on practice. In that scenario, the initial teaching training faces the challenge to create spaces and devices that allow the teaching student to get familiar with a few sets of flexible and changing rules to understand the specificity of the teaching process, from a proper theory-practice relationship.
Docencia universitaria saludable: Una metamorfosis impostergable

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.
Las comunidades indígenas: Una forma de vida que pone en práctica la Carta de la Tierra

Published: May 2016

This paper aims to draw attention to the role that indigenous communities have historically fulfilled by practicing the values proposed in the Earth Charter upon its ancestral construction. The intention is to reflect on the fact that the principles stated in the Earth Charter have been intrinsically performed by these groups on a daily basis. That is, these groups become a role model because they respect life in all its diverse forms, promoting a democratic, participative, sustainable, and peaceful existence, which ensures, the balance of Earth to present and future generations. On the other hand, this paper analyzes the damage caused by human beings, through their unfriendly practices, to Latin American natural resources and therefore to the planet. Moreover, the human species is the only one able to reverse the damage caused. Based on this context, the hope is to place the human being as the center of the planetary system. This requires an education that raises awareness and contributes to the overall view of the problems and takes into account their short, medium, and long term consequences, not only for a community but also for the entire humankind.
