description: We report a tentative correlation between the outflow characteristics derived from OH absorption at $119\,μ\text{m}$ and [CII] emission at $158\,μ\text{m}$ in a sample of 22 local and bright ultraluminous infrared galaxies (ULIRGs). For this sample we investigate whether [CII] broad wings are a good tracer of molecular outflows, and how the two tracers are connected. Fourteen objects in our sample have a broad wing component as traced by [CII], and all of these also show OH119 absorption indicative of an outflow (in 1 case an inflow). The other eight cases, where no broad [CII] component was found, are predominantly objects with no OH outflow or a low-velocity ($\leq 100\,\text{km s}^{-1}$) OH outflow. The full width at half maximum (FWHM) of the broad [CII] component shows a trend with the OH119 blue-shifted velocity, although with significant scatter. Moreover, and despite large uncertainties, the outflow masses derived from OH and broad [CII] show a 1:1 relation. The main conclusion is therefore that broad [CII] wings can be used to trace molecular outflows. This may be particularly relevant at high redshift, where the usual tracers of molecular gas (like low-J CO lines) become hard to observe. Additionally, observations of blue-shifted Na I D $λλ5890,5896$ absorption are available for ten of our sources. Outflow velocities of Na I D show a trend with OH velocity and broad [CII] FWHM. These observations suggest that the atomic and molecular gas phases of the outflow are connected.

description: Large-scale multi-modal contrastive learning frameworks like CLIP typically require a large amount of image-text samples for training. However, these samples are always collected continuously in real scenarios. This paper discusses the feasibility of continual CLIP training using streaming data. Unlike continual learning based on self-supervised learning methods for pure images, which is empirically robust against catastrophic forgetting, CLIP's performance degeneration in the continual setting is significant and non-neglectable. By analyzing the changes in the model's representation space during continual CLIP training from a spatial geometry perspective, we explore and summarize these spatial variations as Spatial Disorder (SD), which can be divided into Intra-modal Rotation and Inter-modal Deviation. Moreover, we empirically and theoretically demonstrate how SD leads to a performance decline for CLIP on cross-modal retrieval tasks. To alleviate SD, we propose a new continual vision-language representation learning framework Mod-X: Maintain off-diagonal information-matriX. By selectively aligning the off-diagonal information distribution of contrastive matrices, the Mod-X improves the capability of the multi-modal model by maintaining the multi-modal representation space alignment on the old data domain during continuously fitting the new training data domain. Experiments on commonly used datasets with different scales and scopes have demonstrated the effectiveness of our method.

description: Amidst the growing popularity of platform engineering, promising improved productivity and enhanced
 developer experience through an internal developer platform (IDP), this research addresses the prevalent
 challenge of a lack of a shared understanding in the field and the complications in defining effective,
 customized strategies. Introducing a definitive Platform Engineering Reference Model (PE-RM) based
 on the Open Distributed Processing reference model (ODP-RM) framework to provide a common under-
 standing. This model offers a structured framework for software organizations to create tailored platform
 engineering strategies and realize the full potential of platform engineering. The reference model is val-
 idated by conducting a case study in which a contextual design and technical implementation guided
 by the reference model is proposed. The case study offers guidance in designing platform engineering in
 the context of a software organization. Furthermore, it showcases how to construct a technical platform
 engineering implementation, which includes experiments exposing the productivity improvements and
 applicability of the implementation. By facilitating a shared vocabulary and providing a roadmap for
 implementation, this research aims to mitigate prevailing complexities and accelerate the adoption and
 effectiveness of platform engineering across organizations.
Symmetric Unique Neighbor Expanders and Good LDPC Codes

description: An infinite family of bounded-degree 'unique-neighbor' expanders was constructed explicitly by Alon and Capalbo (2002). We present an infinite family F of bounded-degree unique-neighbor expanders with the additional property that every graph in the family F is a Cayley graph. This answers a question raised by Tali Kaufman. Using the same methods, we show that the symmetric LDPC codes constructed by Kaufman and Lubotzky (2012) are in fact symmetric under a simply transitive group action on coordinates.
La musicalización de la ficción: intermedialidad encubierta y el rock en Opio en la Nubes de Rafael Chaparro Madiedo

Subjects: subject: Literatura y ciencia
subject: Análisis del discurso narrativo (Retórico)

description: El presente trabajo tiene como finalidad demostrar cómo la novela Opio en las nubes (1994) del escritor colombiano Rafael Chaparro Madiedo presenta una participación activa de la música, en particular del género rock, en su construcción y significación creando el efecto de lo que teóricamente se denomina obra ―musicalizada‖. El propósito principal es evidenciar que tal denominada musicalización no consiste sólo en ―poner música dentro del discurso‖, sino disponer de la música en la obra literaria como mecanismo potenciador de sentido (llegando a afectar el material lingüístico, orden de la estructura narrativa e imágenes y el nivel de la historia) y dando la impresión de estar experimentando la música a través de la lectura. Ha sido de suma importancia en el presente trabajo esclarecer de qué forma se comprende el término ―musicalización‖, dado que no sólo no es un concepto aislado sino que en conjunto con la ficción en prosa, enmarcará cómo abordar la relación intermedial entre ambas formas de arte (música y literatura) disipando la posible confusión que esta pueda ocasionar.

description: BICEP3 is a $550~mm$ aperture telescope with cold, on-axis, refractive optics designed to observe at the $95~GHz$ band from the South Pole. It is the newest member of the BICEP/Keck family of inflationary probes specifically designed to measure the polarization of the cosmic microwave background (CMB) at degree-angular scales. BICEP3 is designed to house 1280 dual-polarization pixels, which, when fully-populated, totals to $\sim$9$\times$ the number of pixels in a single Keck $95~GHz$ receiver, thus further advancing the BICEP/Keck program's $95~GHz$ mapping speed. BICEP3 was deployed during the austral summer of 2014-2015 with 9 detector tiles, to be increased to its full capacity of 20 in the second season. After instrument characterization measurements were taken, CMB observation commenced in April 2015. Together with multi-frequency observation data from Planck, BICEP2, and the Keck Array, BICEP3 is projected to set upper limits on the tensor-to-scalar ratio to $r$ $\lesssim 0.03$ at $95\%$ C.L..

description: Aim: The aim of this thesis is to determine whether sleep quality can predict psychotic symptoms in the general population and more specifically hallucinations and delusions. In addition, the possible mediation of anxiety and depression symptoms was investigated. Method: The data of the present study were drawn from the HELIAD survey (the Hellenic Longitudinal Investigation of Aging and Diet). For the drawing of conclusions, the responses of 1961 participants to the Medical Outcomes Study Sleep Scale Questionnaire, the Columbia and NPI psychiatric questionnaires were analysed. Responses from the Hospital Anxiety and Depression Scale questionnaire (HADS) and the Geriatric Depression Scale (GDS) questionnaire were also used to investigate the role of the respective symptoms in the relationship between sleep and psychotic symptoms. Results: Based on the statistical analysis, it is understood that sleep quality can predict a range of symptoms assessed by the questionnaires used in this study, and that, in some cases, there is also an effect of anxiety and depression symptoms. However, not all findings confirm the existing literature

description: The need for information security within small to mid-size companies is increasing. The risks of information security breach, data loss, and disaster are growing. The impact of IT outages and issues on the company are unacceptable to any size business and their clients. There are many ways to address the security for IT departments. The need to address risks of attacks as well as disasters is important to the IT security policies and procedures. The IT departments of small to medium companies have to address these security concerns within their budgets and other limited resources.Security planning, design, and employee training that is needed requires input and agreement from all levels of the company and management. This paper will discuss security needs and methods to implement them into a corporate infrastructure.

description: This study explores relationships between Taiwanese Sign Language (TSL) and Chinese reading comprehension with 65 deaf adults/youth (study 1: ages 14–50 years) and 27 deaf children (study 2: ages 6–13 years). Significant relationships were found between scores on two tests measuring TSL tasks. In study #1, the TSL tasks (measured by Taiwan Sign Language Comprehension Test, TSLCT) on story and syntax comprehension predicted more of the variance than vocabulary on Chinese reading comprehension. In study #2, TSL tasks measuring vocabulary (using Taiwanese Sign Language Receptive Skills Test, TSL-RST) predicted more of the variance than syntax and story comprehension on Chinese reading comprehension but were not significant. Results are interpreted utilising Cummins’ Linguistic Interdependence Theory and Threshold Hypothesis. Limitations, future research and educational implications are provided.

description: Σκοπός της διατριβής ήταν η μελέτη της σχέσης της χρήσης πορνογραφικού υλικού με την σεξουαλική λειτουργία. Αρχικά, με σκοπό την καλύτερη κατανόηση του ζητήματος, εξετάστηκαν οι όροι σεξουαλικότητα και σεξουαλική δυσλειτουργία. Έπειτα, έγινε προσπάθεια να απαντηθούν συγκεκριμένα ερωτήματα αναφορικά με τις αιτίες και τους παράγοντες που οδηγούν τον σύγχρονο άνθρωπο στην κατανάλωση πορνογραφικού περιεχομένου καθώς και για τις συνέπειες αυτής της χρήσης στη σεξουαλική λειτουργικότητα. Στη συνέχεια, χρησιμοποιώντας τη μέθοδο της συστηματικής ανασκόπησης και μέσω ενδελεχούς αναζήτησης της βιβλιογραφίας, διερευνήθηκε κατά πόσο η χρήση πορνογραφίας στα πλαίσια διαφόρων ηλικιών μπορεί να συσχετιστεί με ποικίλα ψυχοσεξουαλικά προβλήματα τόσο σε άνδρες όσο και σε γυναίκες. Ακόμη, με βάση τα αποτελέσματα έξι σημαντικών ερευνών εξετάστηκε ο ρόλος της πορνογραφίας στη συντροφική σχέση, τη σεξουαλική επίδοση και ικανοποίηση, ενώ ταυτόχρονα ελήφθη υπόψη και ο ενδεχόμενος θετικός αντίκτυπος του προβαλλόμενου περιεχομένου στη σεξουαλική ευημερία των ατόμων. Επιπλέον, δόθηκε έμφαση στη σημασία μιας ευρύτερης κλίμακας σεξουαλικής αγωγής αλλά και στην ανάγκη διεξαγωγής πιο εκτεταμένης έρευνας σχετικά με την επιρροή της ηλεκτρονικής πορνογραφίας καλύπτοντας όλο το φάσμα της ηλικιακής, φυλετικής και σεξουαλικής ποικιλομορφίας
description: The purpose of the dissertation was to study the relationship between the use of pornographic material and sexual function. Initially, in order to better understand the issue, the terms sexuality and sexual dysfunction were examined. Then, an attempt was made to answer specific questions regarding the causes and factors that lead modern man to consume pornographic content as well as the consequences of this use on sexual functionality. Then, using the method of systematic review and through a thorough search of literature, it was investigated whether the use of pornography within different ages can be associated with a variety of psychosexual problems in both men and women. Furthermore, based on the results of six important studies, the role of pornography on intimate partner relationships was examined, while, at the same time, the potential positive impact οf the projected content on the sexual well-being of individuals was taken into account. In addition, emphasis was placed in the importance of a wider range of sex education but also on the need of more extensive research conduct concerning the influence of electronic pornography covering the whole spectrum of age, gender and sexual diversity

description: We propose a strikingly novel, simple, and effective approach to model online user behavior: we extract and analyze digital DNA sequences from user online actions and we use Twitter as a benchmark to test our proposal. We obtain an incisive and compact DNA-inspired characterization of user actions. Then, we apply standard DNA analysis techniques to discriminate between genuine and spambot accounts on Twitter. An experimental campaign supports our proposal, showing its effectiveness and viability. To the best of our knowledge, we are the first ones to identify and adapt DNA-inspired techniques to online user behavioral modeling. While Twitter spambot detection is a specific use case on a specific social media, our proposed methodology is platform and technology agnostic, hence paving the way for diverse behavioral characterization tasks.

description: In a multiband Hubbard model the self-consistency relations for the two-body bound-state bands are in the form of a nonlinear eigenvalue problem. Assuming that the resultant eigenvectors form an orthonormal set, e.g., in the strong-binding regime, here we reformulate their Berry curvatures and the associated Chern numbers. As an illustration we solve the two-body problem in a Haldane-Hubbard model with attractive onsite interactions, and analyze its topological phase diagrams from weak to strong couplings, i.e., by keeping track of the gap closings in between the low-lying two-body bands. The resultant Chern numbers are consistent with the lobe structure of the phase diagrams in the strong-coupling regime.

description: We study the correlation between the value of the triple Higgs coupling and the nature of the electroweak phase transition. We use an effective potential approach, including higher order, non-renormalizable terms coming from integrating out new physics. We show that if only the dimension six operators are considered, large positive deviations of the triple Higgs coupling from its Standard Model (SM) value are predicted in the regions of parameter space consistent with a strong first order electroweak phase transition (SFOEPT). We also show that at higher orders sizable and negative deviations of the triple Higgs coupling may be obtained, and the sign of the corrections tends to be correlated with the order of the phase transition. We also consider a singlet extension of the SM, which allows us to establish the connection with the effective field theory (EFT) approach and analyze the limits of its validity. Furthermore, we study how to probe the triple Higgs coupling from the double Higgs production at the LHC. We show that selective cuts in the invariant mass of the two Higgs bosons should be used, to maximize the sensitivity for values of the triple Higgs coupling significantly different from the Standard Model one.

description: Time reversal and spin flip are discrete symmetry operations of substantial import to quantum information and quantum computation. Spin flip arises in the context of separability, quantification of entanglement and the construction of Universal NOT gates. The present work investigates the relationship between the quantum state of a multiqubit system represented by the Discrete Wigner Function (DWFs) and its spin-flipped counterpart. The two are shown to be related through a Hadamard matrix that is independent of the choice of the quantum net used for the tomographic reconstruction of the DWF. These results would be of interest to cases involving the direct tomographic reconstruction of the DWF from experimental data and in the analysis of entanglement related properties purely in terms of the Discrete Wigner function.

description: Esta investigación tuvo como propósito establecer criterios sobre los factores que permiten reconocer los retos y metas que representa la conflictividad urbana para la escuela y ésta como gestora de paz en el marco del posconflicto, donde se observan fenómenos como el pandillismo, la drogadicción, los conflictos por territorio, el microtráfico, conflictos vecinales y muchos otros, que por supuesto impiden minimizar la conflictividad ocasionada por los conflictos armados y la búsqueda de una paz estable y duradera. El estudio se apoyó en una investigación de tipo mixta, permitiendo establecer un enfoque socio-crítico, donde se recolectaron, analizaron y vincularon datos; en cuya recolección de información se usaron varios métodos entre estos, la técnica de observación participante, entrevistas semiestructuradas y la narrativa. La población estuvo conformada por tres grupos focales (8 estudiantes, 8 docentes y 8 acudientes). Los resultados lograron sentar las bases para la creación de un observatorio de transformación de conflictos en el entorno escolar, que sirviera de espacio para propiciar el diálogo y reflexionar sobre las relaciones de los integrantes de la comunidad educativa y suscitar una cultura de paz que trascienda el espacio escolar. Como conclusión se infiere que las estrategias de transformación de conflictos, que se aspiran aplicar para minimizar los conflictos urbanos reinante en la escuela, como consecuencia del posconflicto armado en Colombia, el cual todavía se encuentran en fase de diseño e implementación, lo que significaría la esperanza tanto a estudiantes, padres, docentes y directivos de la región, para dar inicio al largo camino que debe transitar la escuela en pro de construir una cultura de paz, que permita el surgimiento de un país más democrático y justo.
Transits of extrasolar moons around luminous giant planets

description: Beyond Earth-like planets, moons can be habitable, too. No exomoons have been securely detected, but they could be extremely abundant. Young Jovian planets can be as hot as late M stars, with effective temperatures of up to 2000 K. Transits of their moons might be detectable in their infrared photometric light curves if the planets are sufficiently separated ($\gtrsim10$ AU) from the stars to be directly imaged. The moons will be heated by radiation from their young planets and potentially by tidal friction. Although stellar illumination will be weak beyond 5 AU, these alternative energy sources could liquify surface water on exomoons for hundreds of Myr. A Mars-mass H$_2$O-rich moon around $β$ Pic b would have a transit depth of $1.5\times10^{-3}$, in reach of near-future technology.

The smoother in its original formulation is computationally expensive due to the intrinsic requirement of running the forward and adjoint models repeatedly. Here we present computationally efficient versions of the HMC sampling smoother based on reduced-order approximations of the underlying model dynamics. The schemes developed herein are tested numerically using the shallow-water equations model on Cartesian coordinates. The results reveal that the reduced-order versions of the smoother are capable of accurately capturing the posterior probability density, while being significantly faster than the original full order formulation.

description: Deliverable 5.1 (SDM ed.1) was a first approach to the System Dynamics Model (SDM), as part of the foresight exercise, carried out in WP5. Edition 1 of the SDM was in this sense the first iteration in a process, whose objective is to build a useful tool for guiding conversations and proposing fruitful actions. But at the same time the modules defined in SDM ed.1 are putting the boundaries of the framework for pilots. According to the plan agreed on the General Agreement (GA), Deliverable 5.2 (SDM ed.2) was meant to be a version of the model including fine-tuned individual modules updated with secondary data and primary data obtained in T4.4. The difference of levels in terms of foresight analysis and technical assessment needs has made difficult for the modelling exercise to begin. This is why it has been considered convenient to add simple dissemination models as a guide for the pilots to help them identify dynamics. Deliverable 5.2 (ed.2) includes 1) an enriched version of the model, elaborated with the inputs from T4.4; 2) maps as well as working models ranging from the simplest relation to a more complex model about rural attractiveness; and 3) a guide on the process to be followed to build the models. The Conclusion contains some reflections about the challenges in the work ahead, starting from edition 3 of the model.

description: We study the laser cooling of a mechanical oscillator through the coupling with a dissipative three-level system. Under a background temperature beyond the Lamb-Dicke regime, we extend the standard cooling analysis by separately studying the classical motion and the quantum dynamics of the oscillator. In Ladder-system cooling, the cooling rate degrades by orders of magnitude at large classical motion. This phenomenon causes a critical transition of the final temperature at a hot background. In stark contrast, electromagnetic-induced-transparency (EIT) cooling with a $Λ$-system produces significant negative cooling rate at high motional excitation. At steady state, the oscillator could exhibit both cooling and lasing behaviours. We argue that a successful EIT cooling requires either a poor quality oscillator to suppress the lasing effect, or terminating the cooling process at a transient stage.
Multi-agent market equilibria: mathematical models and empirical analyses
Creators: name: Micheli, Alessandro

description: This thesis examines the framework of multi-agent market equilibria through math- ematical models and empirical analyses. Chapter 2 considers a model for the interaction between a slow institutional investor and a high- frequency trader by means of a stochastic multi-period Stack- elberg game. We determine the unique multi-period Stackelberg equilibrium of the game in terms of the resolvent of a Fredholm integral equation. Our results provide an explicit solution which shows that the high-frequency trader can adopt either predatory or cooperative strategies in each period, depending on the trade-off be- tween the order-flow and the trading signal. We also show that the institutional investor’s strategy is more profitable when the order-flow of the high-frequency trader is taken into account. In Chapter 3 we study a model for a multi-player stochastic differential game, where agents interact through their joint price impact on an asset that they trade to exploit a common trading signal. We prove that a closed-loop Nash equilibrium exists if the price impact parameter is small enough. A comparison with the corre- sponding open-loop Nash equilibrium shows that both the agents’ optimal trading rates and their performance move towards the central-planner solution, since ex- cessive trading due to lack of coordination is reduced. Nevertheless, we find that the size of this effect is modest for plausible parameter values. Chapter 4 develops a methodology which accurately replicates the FTSE Rus- sell indexes reconstruction, including the quarterly rebalancings due to new initial public offerings (IPOs). We apply our index reconstruction protocol to compute the permanent and temporary price impact on the Russell 3000 annual additions and deletions, and on the quarterly additions of new IPOs. Our findings show that the index portfolios following the Russell 3000 index and rebalanced on an annual basis are overall more crowded than those following the index on a quarterly basis.

Ορθοπαιδική Χειροθεραπεία
Κατωφλιακά όρια πόνου
Οσφυαλγία

description: Εισαγωγή: Η οσφυαλγία αποτελεί μια από τις κύριες αιτίες αναπηρίας παγκοσμίως τις τελευταίες 3 δεκαετίες επηρεάζοντας άτομα και των δύο φύλων. Η Ορθοπαιδική Χειροθεραπεία και οι χειρισμοί στην σπονδυλική στήλη προτείνονται, μεταξύ άλλων παρεμβάσεων, για την μείωση του μυοσκελετικού πόνου που προκαλεί η οσφυαλγία και για την αύξηση της λειτουργικής ικανότητας των ασθενών. Οι προσδοκίες των ασθενών αποτελούν παράγοντα αποτελεσματικότητας της θεραπείας και η βελτιστοποίησή τους μπορεί να αυξήσει το θεραπευτικό αποτέλεσμα. Οι αυξημένες προσδοκίες των ασθενών για τους χειρισμούς της σπονδυλικής στήλης συσχετίζονται μακροπρόθεσμα με αυξημένη λειτουργική ικανότητα. Δεν υπάρχουν ερευνητικά δεδομένα για την επίδραση των προσδοκιών στα κατωφλιακά όρια του πόνου. Σκοπός Εργασίας: Να εξετάσει την επίδραση των προσδοκιών για την αποτελεσματικότητα της θεραπείας ως προς την μεταβολή του μηχανικού ουδού του πόνου μετά από έναν στροφικό χειρισμό στο πιο υποκινητικό επίπεδο της οσφυϊκής μοίρας της ΣΣ. Μεθοδολογία: H παρούσα έρευνα αποτελεί μελέτη κοόρτης, στην οποία συμμετείχαν ασθενείς με χρόνια οσφυαλγία μη ειδικής αιτιολογίας, οι οποίοι δέχθηκαν ένα χειρισμό στην οσφύ. Οι προσδοκίες των ασθενών αξιολογήθηκαν με την κλίμακα Expectation for Treatment Scale (ETS) και βάσει αυτής χωρίστηκαν σε ομάδα με υψηλές προσδοκίες (exposed group) και σε ομάδα με χαμηλές προσδοκίες (unexposed group). Η αποτελεσματικότητα του χειρισμού αξιολογήθηκε με την μέτρηση των κατωφλιακών ορίων του πόνου πριν και αμέσως μετά την εκτέλεση του σε τρία τοπικά σημεία (ακανθώδη απόφυση, αμφοτερόπλευρα παρασπονδυλικά του Ο5) και σε τέσσερα απομακρυσμένα (στον άνω τραπεζοειδή και στον πρόσθιο κνημιαίο αμφοτερόπλευρα). Αποτελέσματα: 27 ασθενείς συμπεριλήφθηκαν στην παρούσα έρευνα. Δεν παρατηρήθηκε στατιστικά σημαντική συσχέτιση των προσδοκιών με την κλινικά σημαντική αύξηση των κατωφλιακών ορίων του πόνου. Οι δύο ομάδες δεν παρουσίασαν στατιστικά σημαντική διαφορά ως προς την μεταβολή των κατωφλιακών ορίων του πόνου. Όσον αφορά την αποτελεσματικότητα του χειρισμού, βρέθηκαν στατιστικά σημαντικές μεταβολές στον ουδό του πόνου μόνο στον τραπεζοειδή αμφοτερόπλευρα. Συμπέρασμα: Η παρούσα μελέτη σειράς έδειξε ότι δεν υπάρχει σχέση μεταξύ των προσδοκιών ως παράγοντας έκθεσης με την μεταβολή των κατωφλιακών ορίων του πόνου που βιώνουν ασθενείς με οσφυαλγία αφού υποβληθούν σε στροφικό χειρισμό στην οσφύ.

description: Este documento presenta el proyecto de grado, para graduarnos de la carrera Licenciatura en Pedagogía Infantil. El propósito de este proyecto es demostrar la importancia que tienen la implementación de técnicas grafomotrices como estrategias educativas que repercuten de manera directa en la potencialización visual, psicomotriz de los niños en edad preescolar. El proyecto inicio tras la observación del uso de las técnicas grafomotoras por parte del personal docente de la institución educativa. El siguiente paso fue aprovechar los espacios de práctica, iniciando un proceso de observación directa de la aplicación de la grafomotricidad, pero se descubrió que la aplicación que se hace en el proceso en mención es empírica. Se verificar que los ejercicios realizados no están basados en bases sólidas del SABER, la oportunidad de realizar ejercicios consecutivos con niños que permitiera hacer un seguimiento diario, para analizarlos teniendo en cuenta aspectos lógicos y conceptuales de la grafomotricidad y tomarlos como una muestra representativa que una vez procesada serviría de evidencia. Teniendo en cuenta que la grafomotricidad interviene de forma directa en el aprestamiento de los niños al proceso escritural y a la madurez de movimientos, o más bien permite un mayor dominio de los movimientos del antebrazo, la muñeca la mano y los dedos y de esta forma eviten movimientos inútiles. De tal manera que visionamos la necesidad de buscar la forma de que se aplicara en el desarrollo de enseñanza y aprendizaje de los niveles educativos de preescolar.

description: Begonia sect. Oligandrae M.Hughes & W.N.Takeuchi, sect. nov.
 Type: — Begonia oligandra.
Low growing caulescent herbs, monoecious; stems repent or suberect and adventitiously rooting at the nodes. Leaves alternate, ovate to lanceolate, finely divided or entire. Inflorescences terminal or axillary, cymose, bracts conspicuous, usually persistent, white or pink. Male flowers basal, tepals 3–4, in unequal pairs or one tepal reduced, free, white, stamens 4–8, free, androecium symmetric. Female flowers solitary, terminal, tepals 3–4, in unequal pairs or one tepal reduced, free, white or pink, styles bifid and branched or capitate and cylindrical, not spirally twisted. Fruit 3-locular, placentae axillary, bifid; wings 3, unequal (1+2), fleshy and horn-like, the larger wing extended apically towards the tepals, smaller wings rounded.
 Species list: —Five species. Begonia brassii, B. chambersiae, B. oligandra, B. pentandra sp. nov. and B. sandsiana.
 Distribution: —In montane forests of the New Guinea Highlands, from 900–2300 m, sometimes on karst limestone.
 Etymology: —The epithet is from the Greek oligo (few) and andro (male), referring to the small number of stamens.
 Taxonomic notes: —The affinities of Begonia sect. Oligandrae are difficult to ascertain, primarily because the reproductive structures are unusual and highly modified. Reduced stamen number and showy bracts are similarly found in Begonia sect. Symbegonia (Warburg 1894: 149) Forrest & Hollingsworth (2003: 208) endemic to New Guinea and possibly the closest relative to the new section. However sect. Symbegonia differs (corresponding characters for sect. Oligandrae in parentheses) in usually having solitary-axillary female flowers (female flowers inserted at the apex of a male cymose inflorescence in B. pentandra and B. chambersiae), fused female tepals (free female tepals), noticeably enlarged receptacles (planate or slightly rounded receptacles), and elongated stigmas (stigmas inconspicuous or capitate). Repeated attempts at DNA-sequencing from silica dried leaves of B. sandsiana and B. pentandra were unsuccessful, hence the phylogenetic relationship of the new section remains unknown.
