Time and Space Bounds for Planning
Authors: Bäckström Christer , Jonsson Peter
Published: July 2018

There is an extensive literature on the complexity of planning, but explicit bounds on time and space complexity are very rare. On the other hand, problems like the constraint satisfaction problem (CSP) have been thoroughly analysed in this respect. We provide a number of upper- and lower-bound results (the latter based on various complexity-theoretic assumptions such as the Exponential Time Hypothesis) for both satisficing and optimal planning. We show that many classes of planning instances exhibit a dichotomy: either they can be solved in polynomial time or they cannot be solved in subexponential time. In many cases, we can even prove closely matching upper and lower bounds. Our results also indicate, analogously to CSPs, the existence of sharp phase transitions. We finally study and discuss the trade-off between time and space. In particular, we show that depth-first search may sometimes be a viable option for planning under severe space constraints.
Belief Update within Propositional Fragments
Authors: Creignou Nadia , Ktari Raïda , Papini Odile
Published: July 2018

Belief change within the framework of fragments of propositional logic is one of the main and recent challenges in the knowledge representation research area. While previous research works focused on belief revision, belief merging, and belief contraction, the problem of belief update within fragments of classical logic has not been addressed so far. In the context of revision, it has been proposed to refine existing operators so that they operate within propositional fragments, and that the result of revision remains in the fragment under consideration. This approach is not restricted to the Horn fragment but also applicable to other propositional fragments like Krom and affine fragments. We generalize this notion of refinement to any belief change operator. We then focus on a specific belief change operation, namely belief update. We investigate the behavior of the refined update operators with respect to satisfaction of the KM postulates and highlight differences between revision and update in this context.
A Game Theoretic Analysis of the Adversarial Retrieval Setting
Authors: Ben Basat Ran , Tennenholtz Moshe , Kurland Oren
Published: July 2018

The main goal of search engines is ad hoc retrieval: ranking documents in a corpus by their relevance to the information need expressed by a query. The Probability Ranking Principle (PRP) --- ranking the documents by their relevance probabilities --- is the theoretical foundation of most existing ad hoc document retrieval methods. A key observation that motivates our work is that the PRP does not account for potential post-ranking effects; specifically, changes to documents that result from a given ranking. Yet, in adversarial retrieval settings such as the Web, authors may consistently try to promote their documents in rankings by changing them. We prove that, indeed, the PRP can be sub-optimal in adversarial retrieval settings. We do so by presenting a novel game theoretic analysis of the adversarial setting. The analysis is performed for different types of documents (single-topic and multi-topic) and is based on different assumptions about the writing qualities of documents' authors. We show that in some cases, introducing randomization into the document ranking function yields an overall user utility that transcends that of applying the PRP.
Learning Neural Audio Embeddings for Grounding Semantics in Auditory Perception
Authors: Kiela Douwe , Clark Stephen
Published: July 2018

Multi-modal semantics, which aims to ground semantic representations in perception, has relied on feature norms or raw image data for perceptual input. In this paper we examine grounding semantic representations in raw auditory data, using standard evaluations for multi-modal semantics. After having shown the quality of such auditorily grounded representations, we show how they can be applied to tasks where auditory perception is relevant, including two unsupervised categorization experiments, and provide further analysis. We find that features transfered from deep neural networks outperform bag of audio words approaches. To our knowledge, this is the first work to construct multi-modal models from a combination of textual information and auditory information extracted from deep neural networks, and the first work to evaluate the performance of tri-modal (textual, visual and auditory) semantic models.
Equal channel angular extrusion of semicircular AA 5083 covered with copper casing
Authors: Varadala Ananda Babu , Gurugubelli Swami Naidu , Bandaru Sateesh
Published: July 2018

The microstructural evolution and mechanical behaviour of semicircular AA 5083 billets subjected to equal channel angular extrusion (ECAE), without and with copper casing (CC), are investigated in this work. The semicircular billets, circumferentially covered with and without CC, are extruded up to three passes in route A at room temperature. Even the coarse grain structure of the initial material is significantly refined, the microcracks and the structural defects were observed in the billets extruded without CC due to non-uniform strain distribution. The use of CC on the circumference of the semicircular billets reduces the dead zone effect on the structural homogeneity and minimises the formation of microcracks on the outer periphery of the extruded material. The uniform distribution of the effective strain imposed on the billets ECAE’d with CC enhances the development of equi-axed ultrafine grains at low pressing loads. The newly formed ultrafine grains with a size of few hundreds of nanometres significantly increase the mechanical properties of the ECAE’d AA 5083 with the CC. The obtained results were in good agreement with the earlier reports in which ECAE was carried with back pressure arrangement.

Authors: Escalona-Marfil Carles , Coda Andrea , Ruiz Jorge , Riu-Gispert LluisMiquel , Gironès Xavier
Published: July 2018

An accurate measurement of pain is required to improve its management and research. The Visual Analogue Scale (VAS) on paper format has been shown to be an accurate, valid, reliable and reproducible way to measure pain. However, a few limitations should be considered, some of which can be minimised by replacing the traditional paper version with an electronic version. This study aims to explore new methods of recording pain by comparing the paper VAS with an electronic VAS (eVAS) using the ‘Pain’ Module included in a health App called ‘Interactive Clinics’. A prospective observational cross-sectional studyis proposed. A Force Dial is employed to induce mild pressure symptoms at the participants’ thumbs. Pain is measured using a VAS in paper (10 cm. line) and eVAS. Two statistical approaches are used to evaluate the agreement between the two methods: intraclass correlation coefficient (ICC) analysis and an exploratory Bland - Altman plot analysis.

Surviving Fee-for-Service and Productivity Standards
Authors: Hatchett Gregory T. , Coaston Susannah C.
Published: July 2018

Administrators at community mental health centers have increasingly adopted productivity standards and fee-for-service models for evaluating the performance of their clinical staff. Under these administrative models, the financial risks associated with missed appointments and premature termination—common phenomena at community agencies—have been transferred from the agency as a collective to individual clinicians. These polices may not only lower morale and have financial implications for counselors, but also be at odds with agencies' service missions and result in cost transfers to other social service systems in the community. The purpose of this article is to describe the twin phenomena of fee-for-service and productivity standards, discuss the potential negative consequences of these models for multiple stakeholders, and offer strategies for counselors in persevering in these work environments.
Post-Abuse Boundary Renegotiation: Healing and Reclaiming Self After Intimate Partner Violence
Authors: Czerny Astra B. , Lassiter Pamela S. , Lim Jae Hoon
Published: July 2018

Intimate partner violence (IPV) is a complex set of behaviors that often escalates to physical violence, stalking, or sexual assault. The courage needed to escape an abusive relationship is often compromised by the very abuse itself, which complicates the healing process. As a result, victims of IPV struggle to regain a sense of self and self-in-relationship after leaving IPV. Boundary renegotiation may aid individuals in maintaining safety while simultaneously allowing them to access the supportive relationships needed for healing. This study explores the process of boundary renegotiation that female IPV survivors experience in their healing journey. Utilizing feminist grounded theory and in-depth interviews with 10 IPV survivors, we illustrated the five distinctive stages of boundary renegotiation: (a) prior self: lack of boundary awareness, (b) experiencing abuse: losing boundaries and selfhood, (c) leaving: establishing a clear physical boundary, (d) implementing firm boundaries and safety, and (e) demonstrating flexibility and openness.
Family Communication Patterns and the Mediating Role of Communication Competence and Alexithymia in Relation to Nonsuicidal Self-Injury
Authors: Wester Kelly L. , King Kelly
Published: July 2018

Nonsuicidal self-injury (NSSI) affects a growing number of youth and transitional-aged youth. Nock's (2009) comprehensive model of NSSI engagement points to a range of factors that combine to predict who is at a heightened risk for self-injury. The present study examined the impact of specific interpersonal factors, family communication patterns (i.e., conversation and conformity orientations), and communication competence on five supported measures of self-injurious behaviors. We further tested whether alexithymia, or a person's inability to identify and describe their emotions, mediated family communication patterns and communication competence in predicting NSSI behavior. Family communication patterns, specifically conversation orientation, had a positive impact on lifetime NSSI behaviors. While communication competence positively related to both lifetime and current NSSI behaviors, alexithymia mediated these relationships. Implications for treatment are provided.

Enhancing Features of Library Automation Package by Integrating with Discovery Tool: A Case Study
Authors: Anuradha K. T.
Published: July 2018

The main objective of this paper is to explore the possibility of enhancing search and retrieval features of library automation package by integrating it with a discovery tool. PMB, a library automation package and Vufind, a discovery tool are used for demonstration purposes. PMB was selected as it uses simple LAMP architecture and hence is easy to install and use. But the Online Public Access (OPAC) of PMB does not have many features of new generation OAPCs. However, by integrating PMB into Vufind, which has most of the new generation OPAC features, enhanced features of the OPAC are made available in PMB itself. Also, PMB provides excellent and unique options for record import/export in various formats. This feature is used to export records from PMB and import it to Vufind. Generally, any integrated library automation package (ILAP) contains two modules: staff-client module and Online Public Access catalogue (OPAC). PMB is compatible with international standards: it makes use of Z39.50 server and supports UNIMARC format. Another unique feature in PMB is the facility to convert/ export of records using which records from one format can be converted to about 39 other formats. Though it has many good features, because it uses MySQL as back-end, it lacks many advanced search features in the OPAC. On the other hand, Vufind, a discovery tool uses Solr (Lucene java search library) as its back-end and has good search and retrieval features. For indexing bibliographic records, Vufind uses MARCSolr, through which MARC records are indexed using Solr search engine. This paper reports a study carried out to integrate into PMB search and retrieval features of Vufind.

La disponibilidad de alimentos se refiere a la existencia de cantidades suficientes de alimentos de calidad y variedad que nutren de forma adecuada a una población. Es por ello que se pretende desarrollar una propuesta aplicada a la problemática de seguridad alimentaria en la población de niños de un jardín infantil ubicado en el barrio Santa Bárbara (La Candelaria-Bogotá D.C.), para contribuir al abastecimiento de alimentos, específicamente vegetales. Mediante un estudio descriptivo, se obtuvo que, para los 14 niños, el jardín les suministra 16.693,6 g de vegetales/mes, cuando lo que deberían consumir según la Organización de las Naciones Unidas para la Alimentación y la Agricultura (FAO) es de 42.000 g de vegetales. Para mitigar lo anterior, se optó por realizar charlas y talleres sobre agricultura urbana a los padres de familia, en conjunto con la Casa Comunitaria de Santa Bárbara, donde se prestó el espacio para el desarrollo de estas actividades. Con la propuesta implementada, se cubrió el 65% del déficit de abastecimiento de alimentos vegetales en el jardín, equivalente al cultivo de 140 plantas, y también se evidenció que el 100% de los participantes mostró interés en darle continuidad al proyecto.

La finalidad de este proyecto es evaluar la eficiencia de los humedales artificiales en el tratamiento de agua residual proveniente de la Universidad El Bosque (sede Usaquén) para reutilizarla en riego de plantas y descarga de retretes.

En el proyecto se utilizó el prototipo de humedal artificial subsuperficial de flujo vertical para tratar agua residual doméstica (ARD), donde los modelos construidos contenían tres tipos de plantas, cuatro tipos de suelos y un cultivo de microorganismos eficientes (EM), agregado en uno de ellos, que se dejaron durante un periodo de adaptación a este nuevo ambiente aproximadamente de un mes, para posteriormente poder evaluar los parámetros físicos, químicos y microbiológicos del agua residual . Finalmente se obtuvo un cambio favorable en las muestras tratadas comparándolos con los valores máximos permisibles que dicta la resolución 1207 de 2014 y el decreto 0631 de 2015 del Ministerio de Ambiente y Desarrollo Sostenible, además se demuestra una mayor eficiencia del humedal que contenía los EM.

El entorno físico-social en el que se desarrollan los adultos mayores está asociado al ambiente y bienestar de los mismos. En un centro gerontológico ubicado en el barrio Bonanza de la ciudad de Bogotá D.C., se ha evidenciado que esta población presenta limitantes en cuanto a sus actividades en espacios al aire libre, lo que podría generar monotonía y aislamiento, lo que a su vez, podría traer como consecuencia cambios negativos en su estado de ánimo y comportamiento. Con base en lo anterior, el objetivo de este estudio fue evaluar los jardines verticales como una alternativa para mejorar su estado de ánimo. Se utilizó como soporte (materas), principalmente material reciclable como botellas plásticas de gaseosa y de detergentes, llantas y otros de bajo coste como tela de lona impermeable y tubos de policloruro de vinilo (PVC, por su sigla en inglés) para el cultivo de plantas ornamentales como el dólar (Plectranthus verticillatus), gitana (Coleus blumei), crásula (Crassula ovata), abre caminos (Koanophyllon villosum), pescadito (Nematanthus gregarius) y cinta (Chlorophytum comosum). Luego de la intervención, los adultos mayores mostraron mejoras en su estado de ánimo, por lo cual se concluye que la implementación de estos jardines puede generar efectos positivos en este tipo de población.

En la presente investigación se realizó la propuesta para el diseño de un humedal de flujo subsuperficial empleando Bambusa sp en el tratamiento de aguas residuales domésticas, generadas por la finca el Recreo en Tauramena. La investigación se llevó a través de un alcance descriptivo y alcance cuantitativo, llevando en primera instancia a la caracterización física, química y microbiológica del agua residual doméstica sin tratamiento mediante el análisis de 19 parámetros de calidad; luego de la determinación de la calidad del efluente se comenzó con el diseño y construcción de la prueba piloto con Bambusa sp como macrófita experimental y una segunda prueba con Heliconia psittacorum siendo esta la 
macrófita control. Al agua resultante de las dos pruebas piloto se les realizó las mismas pruebas de calidad que al agua del efluente sin ningún tratamiento, mediante un análisis in situ e in vitro, este último dividido en dos grupos siendo los parámetros más relevantes DBO, DQO, grasas y aceites y fosforo analizados en el laboratorio Biopolab, los demás parámetros en los laboratorios de la Universidad El Bosque. Los resultados de la demanda química de oxígeno para aguas residuales domésticas de 768 mg / L de O2 mostraron una disminución en el parámetro en la prueba piloto utilizando Bambusa sp a 288 mg / L de O2 e incluso más para Heliconia psittacorum De 44,8 mg / L de O2, La demanda bioquímica de oxígeno (DBO) para las aguas residuales no tratadas fue de 446 mg / L de O2, seguida de Bambusa sp correspondiente a 186 mg / L de O2 y la planta de control de 24 mg / L de O2; el total de sólidos en suspensión para aguas residuales domésticas fue de 1407,5 mg / L, la prueba piloto de Bambusa sp de 557,5 mg / L y la prueba piloto Heliconia psittacorum de 516,25 mg / L; (N-NO2-), color, dureza total, alcalinidad total, salinidad y pH (incremento positivo) de los 19 parámetros analizados.
Según los resultados obtenidos en los diferentes análisis se concluye que la eficacia de la Bambusa sp en el tratamiento de aguas residuales domésticas es de un 73% frente a un 79% de la Heliconia psittacorum, siendo esta última más eficiente. Es posible presentar los humedales artificiales como una opción viable para el tratamiento complementario de aguas residuales domésticas, reduciendo los efectos adversos de los vertimientos sobre los medios receptores. Además de ofrecer la opción de reutilizar el efluente tratado como agua de riego para plantas de jardín haciendo de la finca El Recreo sostenible y sustentable en cuanto a su economía generando menor impacto ambiental.
Los semilleros de investigación, lineamiento pedagógico para edificar el aprendizaje en universidades

El presente documento dedica sus esfuerzos a elucidar, más allá de la importancia que tiene la investigación científica en sí misma, la importancia pedagógica que adquieren los «Semilleros de Investigación» para la formación integral de profesionales colombianos. La importancia de recrear con prácticas investigativas las aulas universitarias y los espacios extracurriculares, y la necesidad de asumir propuestas de pensamiento propio con herramientas que posibiliten la construcción efectiva de escenarios para el desarrollo de ese pensamiento en el país, aparecen como exigencias de esa integralidad educacional. Para desarrollar estos argumentos se hará, en primer lugar, una introducción a las categorías de la investigación formativa y de la formación investigativa como tópicos de la relación pedagógica sobre la cual se asientan los Semilleros de Investigación; en segundo lugar, se hará una pequeña semblanza sobre los antecedentes de la formación de los Semilleros de Investigación en Colombia y, posteriormente, se analizará de manera general el trabajo y los objetivos de la Red Colombiana de Semilleros de Investigación RedColsi.
Este trabajo describe la forma como los profesores y estudiantes trabajan en los viveros investigativos dentro del programa de Ingeniería Ambiental. Para ello, se tomó como técnicas los grupos focales (profesores - estudiantes) y a instrumentos las entrevistas estructuradas. Se logró identificar hábitos en los semilleros que deben mejorarse para que, de esta manera, en las universidades se pueda fortalecer la investigación formativa por medio de estos espacios extracurriculares.
Por último se presentan los lineamientos construidos por el investigador y académicos de la Universidad El Bosque para los semilleros de investigación -desde una perspectiva biopsicosocial- finalizando con una propuesta para la articulación y la difusión de una auténtica cultura investigativa en el país.
