Model for interevent times with long tails and multifractality in human communications: An application to financial trading

Social, technological, and economic time series are divided by events which are usually assumed to be random, albeit with some hierarchical structure. It is well known that the interevent statistics observed in these contexts differs from the Poissonian profile by being long-tailed distributed with resting and active periods interwoven. Understanding mechanisms generating consistent statistics has therefore become a central issue. The approach we present is taken from the continuous-time random-walk formalism and represents an analytical alternative to models of nontrivial priority that have been recently proposed. Our analysis also goes one step further by looking at the multifractal structure of the interevent times of human decisions. We here analyze the intertransaction time intervals of several financial markets. We observe that empirical data describe a subtle multifractal behavior. Our model explains this structure by taking the pausing-time density in the form of a superstatistics where the integral kernel quantifies the heterogeneous nature of the executed tasks. A stretched exponential kernel provides a multifractal profile valid for a certain limited range. A suggested heuristic analytical profile is capable of covering a broader region.

Desarrollo de una aplicación interactiva multimedia: Elaboración industrial de una emulsión de fase externa silicónica

A partir de una primera experiencia en el desarrollo de una aplicación interactiva multimedia, como fue la elaboración de comprimidos infantiles de paracetamol y aplicación de las Normas de Correcta Fabricación , y visto que ha tenido una gran aceptación por parte de los alumnos, se decidió el realizar una nueva aplicación interactiva multimedia que considerara la otra práctica que se realizaba en la planta piloto del SDM (Servei de Desenvolupament del Medicament), la cual consiste en la elaboración de una emulsión silicónica. Ambas prácticas se llevan a cabo presencialmente en la asignatura de Tecnología Farmacéutica II. En esta segunda aplicación multimedia, si bien se ha mantenido una estructura similar a la primera editada, se ha intentado mejorar todos aquellos aspectos que surgieron durante la programación y la fase de pruebas de dicha multimedia, como por ejemplo el más importante que ha sido el utilizar un tipo de programación que permita visualizar la actividad a través de Internet entre otras muchas mejoras. Además en esta nueva aplicación se ha introducido una actividad que consiste en un simulador de la elaboración de una emulsión en donde los alumnos podrán probar diferentes parámetros de fabricación (velocidad y tiempo de agitación) para encontrar aquellos que den unas características de viscosidad y extensión lo más óptimas posibles. A día de hoy faltan todavía algunos ajustes a dicha aplicación que se pretende ensayar en el curso académico 2004-2005 donde se valorará por parte de los alumnos y profesores su aplicabilidad y su aceptación real. En esta comunicación se presenta las áreas desarrolladas.

Estudio comparativo entre los resultados de una actividad didáctica sobre normas de correcta fabricación en formato multimedia y en formato papel

Se desarrolló una actividad didáctica (Te’n recordes de les NCF?, eminentemente práctica, en dos formatos, multimedia y papel) para reafirmar y evaluar los conocimientos sobre Normas de Correcta Fabricación (NCF) de los alumnos de la asignatura Farmàcia Galènica III.Se describe el estudio llevado a cabo para estudiar si existían diferencias significativas en los resultados obtenidos por los alumnos debidas al empleo de un material interactivo (aplicación para el ordenador) o un material tradicional (ejercicio en papel y escrito).

TransPromo communication as a part of company’s marketing communications when the e-bill is a medium

The goal of this thesis was to research what TransPromo is, why companies want to implement TransPromo communication, and what the elements of effective Transpromo communication are. Furthermore, the goal was to develop a TransPromo communication strategy and a normative model for TeliaSonera Finland, which depicts the elements of effective TransPromo communication when the electronic bill is a medium. Abductive reasoning was utilized in this thesis, which means that empirical and theoretical worlds are alternating in researcher’s reasoning process. This thesis didn’t rely on any specific theory nor did it utilize any previous theoretical model. However, certain theoretical connections existed so this thesis cannot be considered purely inductive. The empirical part of this thesis was conducted by examining secondary industry data and by conducting specialist interviews at TeliaSonera Finland and Strålfors. Grounded Theory approach was utilized in the analysis of the interview data and content analysis was used in the analysis of secondary industry data. This thesis increases knowledge in the area of TransPromo communication, and provides one definition of TransPromo communication. As a result of this thesis, a TransPromo communication strategy and a normative model for TeliaSonera Finland was built. The model depicts the elements of the effective TransPromo communication when the e-bill is a medium. The TranPromo communication objective is to utilize transaction documents, such as bills, in order to deliver targeted and personalized marketing messages to current customers. The aim is to strengthen the customer relationship, and to enforce up-sell and cross-sell opportunities and cost savings.

Multimedia johtajakoulutuksessa : teoreettinen tarkastelu multimedian käytettävyydestä varusmiesten johtajakoulutuksen opetuksessa

Tutkimuksessa selvitettiin interaktiivisen multimedian käytettävyyttä varusmiesten johtajakoulutuksessa ja kuinka multimedia opetusmateriaalina tukee johtajakoulutuksen keskeisten tavoitteiden saavuttamista. Samalla tutkimuksessa haluttiin jäsentää johtajakoulutuksen teoriataustaa ja multimediaoppimisen kognitiivisia prosesseja. Tutkimuksen kohteena oli johtajakoulutuksessa käytössä oleva Johtajakoulutus -multimediaopetusmateriaali. Tutkimus toteutettiin laadullisena teoreettisena tutkimuksena. Tutkimuksen teoreettisena viitekehyksenä ovat multimedia opetusvälineenä, oppiminen kognitiivisena prosessina sekä konstruktivistinen oppimiskäsitys ja transformatiivinen oppiminen. Oppimisen kognitiivista prosessia tarkasteltiin multimediaoppimisen kognitiivisen teoriaan pohjautuen. Tutkimuksen aineistona olivat aihealueeseen liittyvä kirjallisuus ja aikaisempi tutkimus sekä Johtajakoulutus - multimedia. Multimediaa analysoitiin teorialähtöisen sisällönanalyysin keinoin. Tutkimuksen pääongelmana oli selvittää miten multimedia opetusvälineenä tukee johtajakoulutuksen kasvatustavoitteen ja syväjohtaminen -oppimisohjelman oppimistavoitteiden saavuttamista. Tutkimuksessa ilmeni, että multimedia soveltuu erityisesti itseopiskeluun tarjoamalla riittävästi informaatiota johtajakoulutuksen keskeisimmistä opetussisällöistä. Multimedia opetusmateriaalina antaa monipuolisia mahdollisuuksia tukea lähiopetusta. Kouluttajien opetustyötä ja multimedian tehokasta opetuskäyttöä tukisi multimediaan käyttöön liittyvä pedagoginen käsikirjoitus. Johtajakoulutus -multimedian toteutus vastasi hyvin multimediaoppimisen kognitiivisen teorian periaatteita ja sen monipuolinen sisältö tukee konstruktivistisen oppimiskäsityksen mukaista oppimista. Teoreettisen tarkastelun perusteella multimedia soveltuu hyvin johtajakoulutuksen opetusmateriaaliksi. Jatkotutkimuksella olisi tarpeellista selvittää kouluttajien ja oppijoiden kokemuksia multimedian käytöstä sekä sen avulla saavutettavista oppimistuloksista.

DIGITAL BUSINESS-TO-BUSINESS MARKETING COMMUNICATIONS IN EMERGING MARKETS – Developing Business Marketing in Russia

The core idea of this Master's Thesis was that five key characteristics – market heterogeneity, sociopolitical governance, chronic shortage of resources, unbranded competition, and inadequate infrastructure – of emerging markets are radically different from the traditional industrialized capitalist society and they will require us to rethink the core assumptions of business-to-business marketing, such as business relationships, marketing communication elements, and digitalization. In this research, Russia is considered to be an emerging market that reflects the aforementioned theoretical characteristics. The research was a qualitative case study and furthermore a collective case study. In the beginning three digital marketing professionals were interviewed to better understand digital B2B marketing. The actual research data was collected through seven structured theme interviews with representatives of the case companies operating in Russia. The selection of case companies included three business consulting companies and four industrial companies. The aim of this qualitative study was to understand and clarify how business marketing exploits digital marketing methods as a part of the chosen business marketing strategy under emerging markets’ special conditions. This objective was divided in three research questions: 1) How the chosen marketing strategy reflects in the business marketing process? 2) How digital marketing communication contributes to business marketing? 3) How are the emerging markets’ characteristics reflected in the business marketing process? The main research findings indicate that digital business-to-business marketing communications can be useful and effective. Moreover, business DMC can be defined and structured in a reasonable way. The company's prevalent marketing paradigm and the chosen marketing strategy reflect in the business marketing process, and in utilizing digital marketing communications. The assumption that emerging markets set an environment with special characteristics for business marketing was supported by the study. However, the business environmental aspects were not considerably disturbing digital B2B marketing, but making it even more reasonable to harness in Russia.
