    Expert finding is a key task in enterprise search and has recently attracted lots of attention from both research and industry communities. Given a search topic, a prominent existing approach is to apply some information retrieval (IR) system to retrieve top ranking documents, which will then be used to derive associations between experts and the search topic based on cooccurrences. However, we argue that expert finding is more sensitive to multiple levels of associations and document features that current expert finding systems insufficiently address, including (a) multiple levels of associations between experts and search topics, (b) document internal structure, and (c) document authority. We propose a novel approach that integrates the above-mentioned three aspects as well as a query expansion technique in a two-stage model for expert finding. A systematic evaluation is conducted on TREC collections to test the performance of our approach as well as the effects of multiple windows, document features, and query expansion. These experimental results show that query expansion can dramatically improve expert finding performance with statistical significance. For three well-known IR models with or without query expansion, document internal structures help improve a single window-based approach but without statistical significance, while our novel multiple window-based approach can significantly improve the performance of a single window-based approach both with and without document internal structures

    Expert Finding in Disparate Environments

    Providing knowledge workers with access to experts and communities-of-practice is central to expertise sharing, and crucial to effective organizational performance, adaptation, and even survival. However, in complex work environments, it is difficult to know who knows what across heterogeneous groups, disparate locations, and asynchronous work. As such, where expert finding has traditionally been a manual operation there is increasing interest in policy and technical infrastructure that makes work visible and supports automated tools for locating expertise. Expert finding, is a multidisciplinary problem that cross-cuts knowledge management, organizational analysis, and information retrieval. Recently, a number of expert finders have emerged; however, many tools are limited in that they are extensions of traditional information retrieval systems and exploit artifact information primarily. This thesis explores a new class of expert finders that use organizational context as a basis for assessing expertise and for conferring trust in the system. The hypothesis here is that expertise can be inferred through assessments of work behavior and work derivatives (e.g., artifacts). The Expert Locator, developed within a live organizational environment, is a model-based prototype that exploits organizational work context. The system associates expertise ratings with expert’s signaling behavior and is extensible so that signaling behavior from multiple activity space contexts can be fused into aggregate retrieval scores. Post-retrieval analysis supports evidence review and personal network browsing, aiding users in both detection and selection. During operational evaluation, the prototype generated high-precision searches across a range of topics, and was sensitive to organizational role; ranking true experts (i.e., authorities) higher than brokers providing referrals. Precision increased with the number of activity spaces used in the model, but varied across queries. The highest performing queries are characterized by high specificity terms, and low organizational diffusion amongst retrieved experts; essentially, the highest rated experts are situated within organizational niches

    Es importante establecer y visibilizar a los estudiantes los beneficios relacionados con la formación en investigación, dentro de los cuales encontramos el fortalecimiento de las capacidades de liderazgo así como el compromiso activo y las experiencias en independencia y colaboración. Así mismo, la formación integral hacia una mayor apreciación del valor de la literatura disciplinaria, generando de esta manera habilidades de pensamiento crítico, indagación y análisis. Además, esto permite forjar la confianza en sí mismo para presentar las propias ideas a la comunidad, permitiendo al estudiante la preparación de futuras actividades académicas, incluidos estudios de posgrado. La investigación formativa tiene como propósito la difusión de la información existente y permitir que el estudiante la integre como conocimientos, considerándolo como un aprendizaje permanente y necesario. Uno de los principales problemas que debe enfrentar la investigación formativa es el número de docentes con las capacidades necesarias para generar en el estudiante capacidades investigativas, exigiendo al profesor universitario adoptar una actitud contraria al objeto de enseñanza, generando un carácter complejo y dinámico del conocimiento.CONTENTS RETOS DE LA INVESTIGACIÓN EN PREGRADO..................................................5 CHALLENGES OF UNDERGRADUATE RESEARCH.............................................9 German Oved Acevedo Osorio CHAPTER 1 HEALTH AND SPORTS SCIENCES FACTORS ASSOCIATED WITH EXACERBATIONS OR CRISIS EVENTS OF CHRONIC NON COMMUNICABLE DISEASES.........................13 Giovanni García Castro, Sandra Milena Bedoya Gaviria, Isabela Patiño Pulgarín y Valentina Valencia Flórez ORAL ANTICOAGULATION IN PATIENTS WITH NON-VALVULAR ATRIAL FIBRILLATION IN A UNIVERSITY HOSPITAL IN COLOMBIA.....................................................................................................29 María Leonor Galindo Márquez, Adrian Giraldo Diaconeasa, Juan Darío Franco Ramírez y Eduardo Ramírez Vallejo PERFORMANCE IN INITIAL TRAUMAASSESSMENT OF EMERGENCY TEAMS FROM PREHOSPITAL CARE TEAMS..................43 Giovanni García Castro, Yamileth Estrada Berrio, Manuela Aguirre Torres e Isabella Díaz Leal ACADEMIC TRAINING AND WORKING CONDITIONS OF NURSING PROFESSIONALS IN PEREIRA - RISARALDA 2020.....................55 Miguel Ángel Gómez Puerta, Laura Isabel Orozco Santamaría, Alexandra Villa Patiño y Gladys Judith Basto Hernández EFFECTS OF DYNAMIC TAPE WITH ANTI-VALGUS APPLICATION ON VERTICAL JUMP PERFORMANCE IN PHYSICALLY ACTIVE WOMEN: A CASE STUDY ..........................................73 María Camila Arias Castro, Alejandro Gómez Rodas y Ángela María Cifuentes Ríos PROPOSAL OF CARE FOR DIAGNOSTIC PREVALENT NURSES IN AN EMERGENCY DEPARTMENT................................................................89 Tatiana Restrepo Pérez, Jessica Viviana Ríos Uribe, Anyi Daniela Lemos Córdoba, Anyi Katherine Mapura Benjumea and Mónica Margarita Barón Castro FACTORS AND CONCEPTS ASSOCIATED WITH THE INITIATION OF CIGARETTE CONSUMPTION IN UNIVERSITY STUDENTS OF PEREIRA, COLOMBIA ............................................................................... 113 Giovanni García Castro, Claudia Milena Bernal Parra, Natalia Cardona Arroyave, Brahiam Stiven Moreno Bustamante y Daniela Ospina Sierra CHAPTER 2 ECONOMIC, ADMINISTRATIVE AND ACCOUNTING SCIENCES TECHNICAL-FINANCIAL EVALUATION OF BEAN (PHASEOLUS VULGARIS) VARIETY CARGAMANTO IN THE VILLAGE OF THE MUNICIPALITY OF SIBUNDOY IN THE DEPARTMENT OF PUTUMAYO ................................................................................................ 131 Adriana María Cuervo Rubio, Alejandra Arango Baranza IMPLEMENTATION OF THE NIF IN MICRO-ENTERPRISES OF PEREIRA CITY ............................................................................................ 151 Laura Cortes Correa y Nataly Andrea Gutiérrez STRATEGIC FRAMEWORK FOR SUSTAINABLE PRODUCTION IN COLOMBIA................................................................................................... 163 Paulina Murillo Gómez, Manuela Ramírez Osorio, Laura Juliana Rodríguez Henao, Lindy Neth Perea Mosquera, Isabel Redondo Ramírez SUSTAINABLE INNOVATION IN MANUFACTURING INDUSTRY........... 179 Mariana Buitrago Zuleta, Laura Juliana Rodríguez Henao, Lindy Neth Perea Mosquera y Marlen Isabel Redondo Ramírez CHAPTER 3 ARTS, HUMANITIES AND SOCIAL SCIENCES PERSONAL AND FAMILY CHANGES OF UNDERGRADUATE PSYCHOLOGY STUDENTS.

    Systems between information and knowledge : In a memory management model of an extended enterprise

    The research question of this thesis was how knowledge can be managed with information systems. Information systems can support but not replace knowledge management. Systems can mainly store epistemic organisational knowledge included in content, and process data and information. Certain value can be achieved by adding communication technology to systems. All communication, however, can not be managed. A new layer between communication and manageable information was named as knowformation. Knowledge management literature was surveyed, together with information species from philosophy, physics, communication theory, and information system science. Positivism, post-positivism, and critical theory were studied, but knowformation in extended organisational memory seemed to be socially constructed. A memory management model of an extended enterprise (M3.exe) and knowformation concept were findings from iterative case studies, covering data, information and knowledge management systems. The cases varied from groups towards extended organisation. Systems were investigated, and administrators, users (knowledge workers) and managers interviewed. The model building required alternative sets of data, information and knowledge, instead of using the traditional pyramid. Also the explicit-tacit dichotomy was reconsidered. As human knowledge is the final aim of all data and information in the systems, the distinction between management of information vs. management of people was harmonised. Information systems were classified as the core of organisational memory. The content of the systems is in practice between communication and presentation. Firstly, the epistemic criterion of knowledge is not required neither in the knowledge management literature, nor from the content of the systems. Secondly, systems deal mostly with containers, and the knowledge management literature with applied knowledge. Also the construction of reality based on the system content and communication supports the knowformation concept. Knowformation belongs to memory management model of an extended enterprise (M3.exe) that is divided into horizontal and vertical key dimensions. Vertically, processes deal with content that can be managed, whereas communication can be supported, mainly by infrastructure. Horizontally, the right hand side of the model contains systems, and the left hand side content, which should be independent from each other. A strategy based on the model was defined.Tutkimuksen tavoitteena oli määrittää, miten tietojärjestelmiä voidaan käyttää organisaatioiden tietämyksen hallintaan. Johtopäätöksenä voidaan sanoa, että järjestelmillä voidaan tukea, mutta ei korvata tietojohtamista. Tietojärjestelmiä voidaan käyttää lähinnä organisaation episteemisen tiedon muistina, prosessoitavan tiedon varastointiin. Oleellista lisäarvoa saadaan, jos viestintäteknologiaa käytetään tietojärjestelmien tukena. Kommunikaatiota ei kuitenkaan voida johtaa, sillä se ei perustu prosesseihin, vaan enintään työnkulkuun ja sitä vapaampaan viestintään. Hallitun informaation ja viestinnän välille syntyy knowformaatioksi nimetty kerros, lähinnä organisaatioiden lyhytkestoiseen muistiin. Uusi knowformaatio-käsite on käytännön tapaustutkimusten tulos. Vastaavaa ei aiemmissa tietojohtamisen tutkimuksissa ole esitetty. Tietojohtamisen kirjallisuuden taustaksi tutkittiin fysiikan, filosofian, viestinnän ja tietojenkäsittelytieteen luokitukset. Tapaustutkimuksissa tarkasteltiin useita datan hallinnan, dokumentaation ja tietojohtamisen järjestelmiä organisaation sisäisissä ryhmissä, organisaation laajuisesti sekä organisaation yhteistyökumppaneiden kanssa. Tapauksissa tutkittiin niin järjestelmien ominaisuudet kuin myös eri sidosryhmien kokemukset. Tutkimuksessa tietojärjestelmät luokiteltiin organisaation muistin ytimeen. Knowformaation kerrosta tarvitaan toisaalta koska filosofisen tiedon episteemistä kriteeriä ei edellytetä järjestelmien sisällöltä (eikä tietojohtamisen kirjallisuuden käsitemäärittelyissä) ja toisaalta koska tiedon uudelleenkonstruoinnissa merkitys muuttuu. Tulevien järjestelmien suunnitteluun tarvitaan uusi näkökulma, koska data, informaatio ja knowledge tasojen hierarkia ei erotu eri järjestelmätyyppien käyttäjien sosiaalisesti konstruoidussa todellisuudessa. Tieteen filosofian skaala positivistisesta konstruktivistiseen oli mallin muodostuksessa oleellinen, ja sen validiuden todentamisen jälkeen eksplisiittinen piiloinen -dikotomia mallinettiin uudelleen knowformaatio-käsitteen avulla. Uusi tietomalli ja knowformaatio-käsite tarvitaan työn päätuloksessa, jatketun organisaation muistin hallintamallissa. Sen ääripäihin kuluvat kommunikaatio, jota tuetaan, ja toisessa päässä prosessit, joita hallitaan. Kahden muun entiteetin, järjestelmien ja niiden sisällön, tulisi olla riippumattomia toisistaan. Knowformaatio elää näiden kokonaisuuksien implisiittisillä rajoilla, informaation ja tiedon välisellä harmaalla alueella

    Nation, society and the state : the reconciliation of palestinian and jewish nationhood

    La nation comme entité sociale existe en raison d'une dynamique socio-économico-culturelles. Une société civile est le berceau d'une conscience collective donnant naissance à une personnalité commune, un soi-disant 'esprit national', une culture politique, une histoire, et peut-être une religion ou, une philosophie existentielle, ou une épistémologie. L'État-Nation devient un phénomène transitoire correspondant aux classes sociales, au genre et aux relations nationales répandues dans la société. La revendication d'une autodétermination est fondamentale face à l'impasse d'un conflit social basé sur 'la question nationale' et ces contradictions, comme l'avancent les théories classiques. Chaque partie du conflit fait des demandes basées sur son existence par principe, indépendamment des autres revendications semblables. Ainsi, la revendication nationale à l'autodétermination est considérée comme problématique puisqu'elle constitue des propositions mutuellement exclusives. Un examen de l'antinomie entre 'le moi' et 'le non-moi' permet de faire apparaître une méthodologie rendant possible la poursuite de l'analyse du conflit national. La différenciation entre la nation société, et l'État (et autres connotations idéologiques) permet à la conception de la société civile d'émerger comme un contexte favorable à la Nation. En conséquence, la distinction entre identités nationales et l'idéologie du nationalisme a permis la conservation de l'identité de la Nation dans le cadre d'une société commune. Par l'observation du conflit entre les peuples palestiniens-nes et Israël, l'analyse de la culture nationale permet de trouver les bases pour la réconciliation de leurs existences nationales en tant que Peuples, fondé ici sur des droits mutuels selon un principe de réciprocité. La méthode par laquelle la résolution de conflits nationaux permet la réconciliation devient la base pour la formation de la société civile, en tenant compte de la composition plurinationale de la population elle même prête à former une association fondée sur l'autonomie de ses diverses communautés de façon réciproque. De plus, de telles relations devraient être codifiées dans des dispositions constitutionnelles, symbolisant une telle réconciliation.\ud ______________________________________________________________________________ \ud MOTS-CLÉS DE L’AUTEUR : Nation, autodétermination, état, autonomie, société, société civile, Palestinien, Palestinienne, Palestine, Juive, Juif, Israélien, Israélienne, Israël, sioniste, sionisme, la question nationale, peuple, culture, Bund, Bundis
