Credibility of online comments in the HPV vaccination discussion in Finnish online forums

2016

Internet ja lukuisat online-kanavat ja -foorumit ovat mahdollistaneet reaaliaikaisen kom-mentoinnin lähes jokaiselle ja näin yleisöistä ja sisällön kuluttajista on tullut sisällöntuottajia. Sisällöt voivat myös ohjailla kuluttajien käyttäytymistä. Kuluttajien tuottaman sisällön suuri määrä on johtanut siihen, että online-sisältöjen luotettavuuden arvioimisesta on tullut entistä tärkeämpää ja organisaatioiden täytyy ennakoida ja hallita heitä käsittelevää verkkokeskustelua. Tavallisten ihmisten kirjoittamat word of mouth -arviot verkossa koetaan usein luotettavammiksi kuin markkinointitekstit ja mainonta. Lisäksi yksilöiden välinen verkkokeskustelu on usein empaattisempaa kuin vastaava viran…

"Naturally wired to learn" : beliefs about SLA in an online community

2013

Tämän tapaustutkimuksen tarkoituksena on kartoittaa tofugu.com – kieli- ja kulttuuriyhteisön uskomuksia kielenoppimisesta. Tutkimuksen tavoitteena on selvittää, mitä oppimisuskomuksia yhteisön keskusteluissa esiintyy, miten ne rakentuvat julkaisijan artikkeleissa sekä yleisön ja julkaisijan välisissä diskursseissa. Tutkin tätä analysoimalla syys- marraskuussa 2011 julkaistua kielenoppimiseen liittyvää artikkelisarjaa kommentteineen. Vastaavaa internetyhteisön oppimisuskomuksia kartoittavaa tutkimusta ei ole aikaisemmin tehty. Tutkielmani teoriatausta ja viitekehys pohjautuu Vygotskin sosiaalisen konstruktivismin oppimiskäsitykseen, jonka mukaan muokkaamme tietoamme sosiaalisissa konteksteis…

On the accuracy of three statistical softwares

2005

In this paper we compare the accuracy of three packages that are commonly used for statistical calculations: Excel of Microsoft, version XP Edition 2003, Statistica of Statsoft, version 6, and R, an open-source free software, available on the web, version 1.9.0. To assess the accuracy of each software in different statistical areas, we are going to use benchmarks expressly developed for this aim. The obtained results show a superiority of R in comparison with the other two softwares.

Global linear feedback control for the generalized Lorenz system

2006

Abstract In this paper we show how the chaotic behavior of the Chen system can be controlled via feedback technique. We design both a nonlinear feedback controller and a linear one which globally regulate the closed-loop system states to a given point. We finally show that our approach works also for the whole family of the generalized Lorenz system.

Harmonic balance analysis of pull-in range and oscillatory behavior of third-order type 2 analog PLLs

2020

The most important design parameters of each phase-locked loop (PLL) are the local and global stability properties, and the pull-in range. To extend the pull-in range, engineers often use type 2 PLLs. However, the engineering design relies on approximations which prevent a full exploitation of the benefits of type 2 PLLs. Using an exact mathematical model and relying on a rigorous mathematical thinking this problem is revisited here and the stability and pull-in properties of the third-order type 2 analog PLLs are determined. Both the local and global stability conditions are derived. As a new idea, the harmonic balance method is used to derive the global stability conditions. That approach…

Nonlinear Feedback Control and Stability Analysis of a Proof-of-Work Blockchain

2017

In this paper a novel feedback controller and stability analysis of a blockchain implementation is developed by using a control engineering perspective. The controller output equals the difficulty adjustment in the mining process while the feedback variable is the average block time over a certain time period. The computational power (hash rate) of the miners is considered a disturbance in the model. The developed controller is tested against a simulation model with constant disturbance, step and ramp responses as well as with a high-frequency sinusoidal disturbance. Stability and a fast response is demonstrated in all these cases with a controller which adjusts it's output at every new blo…

Quando il diario diventa virtuale: il personal blog ovvero esserci online

2007

Il presente contributo esplora alcuni correlati psicologici del personal blog, de- finibile come un diario online. Il blogger crea facilmente il suo spazio in Rete, nel quale riporta e condivide con altre persone, gli eventi, i pensieri, le sensazioni, le emozioni della vita quotidiana. Tale strumento comunicativo, particolarmente dif- fuso fra i giovani, sembra così soddisfare il bisogno di esibire online la propria i- dentità, in contrasto con la tendenza opposta ad occultarla dietro l’anonimato o die- tro fantasiosi avatar, come accade ad esempio in Second Life.

Paths to purchase : the role of the online environment and the fluctuation of customer brand engagement

2016

Customers´ paths to purchase are constantly developing due to digitalization. Online channels enable customers to guide their own decision processes more than ever. When understanding the complex buying journeys, companies can gain competitive advantage. Another current and interesting phenomena in the field of marketing lies in a fairly new concept called customer brand engagement (CBE). The nature of CBE has been studied to some extent, but further research is needed, especially on fluctuation, since most research focuses on observing CBE levels during a specific context and time. The aim of this research is to create insight into the customer decision-making process and CBE. The focus is…

The relationship between brand love and positive word of mouth

2014

Being able to create strong emotional bonds between consumers and brands can be seen as an important goal of today’s brand management. As in interpersonal relationships also in product and brand context love is presented to be the strongest stage of emotional attachment a consumer may have. Brand love is previously discovered to have several desirable outcomes from marketing perspective but the understanding of this phenomenon still remains in its infancy. The objective of this research was to gain a better insight of the construct of brand love by observing how the three following phenomena, self-expressiveness of a brand, brand trust and hedonic product type affect brand love. In addition…
