Women fighters as agents of change: A Brazilian jiu jitsu case study from Finland
2015
Brazilian jiu jitsu (BJJ), a grappling system of combat, evolved from the teachings of a Japanese judoka who moved to Brazil in the 1920s. Focusing on ground fighting, BJJ is rapidly evolving into a combat sport with competitions taking place worldwide (Hogeveen and Hardes, 2014; Spencer, 2014). Unique to the BJJ culture is the way that the ‘secrets’ of the sport are transferred from expert to novice and from one club to the other. Clubs are organised into international ‘teams’, shaping global communities of practitioners that share techniques and philosophies. Unlike many other martial arts that insist on the traditional way of passing knowledge from one teacher to many students behind the…
A basic need theory approach to problematic Internet use and the mediating effect of psychological distress
2015
The Internet provides an easily accessible way to meet certain needs. Over-reliance on it leads to problematic use, which studies show can be predicted by psychological distress. Self-determination theory proposes that we all have the basic need for autonomy, competency, and relatedness. This has been shown to explain the motivations behind problematic Internet use. This study hypothesizes that individuals who are psychologically disturbed because their basic needs are not being met are more vulnerable to becoming reliant on the Internet when they seek such needs satisfaction from online activities, and tests a model in which basic needs predict problematic Internet use, fully mediated by p…
Panorámica de la desigualdad digital en España: operacionalización y dimensionamiento de las brechas digitales de accesibilidad, habilidades y formas…
2019
En este artículo, se realiza un análisis estadístico de la desigualdad digital en España a partir de una operacionalización de las tres brechas digitales más relevantes: (1) accesibilidad a los dispositivos TIC; (2) competencias y habilidades digitales; y (3) prácticas digitales y formas diferenciales de uso. La metodología es cuantitativa, basada en la última oleada (2018) de la encuesta sobre equipamientos tecnológicos en el hogar del INE (TIC-H), a partir de la cual se ha desarrollado un análisis comparativo por género, edad, nivel de estudios, situación laboral y tipo de hábitat residencial. Los resultados muestran cómo la desigualdad de acceso tiene actualmente más que ver con las moda…
Recenti tendenze in tema di responsabilità degli intermediari di Internet nella tradizione giuridica occidentale
2019
Il saggio prende in esame il dibattito circa la necessità di modificare gli attuali regimi di irresponsabilità degli intermediari della rete, dibattito in corso nelle esperienze statunitense ed unitaria europea. Con riferimento all’esperienza statunitense, non è chiaro, infatti, se il ricorso sempre più frequente alla procedura di notice and take down sia sintomo del successo del sistema di notice based liability, congegnato dal legislatore federale nel 1998 o sia, al contrario, espressione del suo fallimento. In tale ottica, al fine di verificare la possibilità di transitare da un sistema di notice and take down ad un sistema di notice and stay down, il saggio prende in esame le recenti in…

Web crawling dla celów lingwistycznych. Wybrane aspekty gromadzenia i analizy danych tekstowych na przykładzie rosyjskojęzycznych newsów internetowych
2021
Autor niniejszego artykułu zgromadził ok. 2,7 mln rosyjskojęzycznych newsów internetowych. Zasadnicze cele tego tekstu stanowią: omówienie pojęcia web crawlingu w odniesieniu do pozyskiwania internetowych danych tekstowych, omówienie kwestii strukturyzacji takich danych w nieanotowanych korpusach tekstowych, a także przedstawienie wybranych aspektów analizy danych strukturyzowanych w ten sposób. Autor rozpatruje newsy internetowe jako połączenie tekstu zasadniczego oraz identyfikujących i charakteryzujących go metadanych (wyróżnionych podczas automatycznej ich ekscerpcji ze stron internetowych). Rozdział newsów na tekst zasadniczy i metadane stwarza możliwość przeprowadzenia ich analizy z d…
Organisaatioiden verkkopresenssi
2014
Tässä tutkielmassa tarkastellaan organisaatioiden verkkopresenssin tutkimusta systemaattisen kirjallisuuskatsauksen avulla. Verkkopresenssi tarkoittaa organisaation muodostamaa kuvaa itsestään verkkoviestinnässä niin verkkosivuilla kuin sosiaalisen median palveluissa. Aineisto koostui 16 artikkelista, jotka tarkastelevat organisaatioiden verkkopresenssiä viestinnän näkökulmasta. Tutkielman tarkoituksena oli selvittää millaisena organisaatioiden verkkopresenssi nähdään tutkimuksissa, mitä tutkimustulokset kertovat organisaatioiden verkkopresenssistä ja millaisia jatkotutkimus-ehdotuksia artikkeleissa on esitetty. Tuloksista käy ilmi, että verkkopresenssin käsitteestä käytetään useita eri nim…
Understanding Big Data and its application in the digital marketing landscape
2021
This chapter outlines the increasing prominence of Big Data and its application to marketing practice. The 8Ps of the Expanded Marketing Mix: Product, Price, Place, Promotion, Process, Physical evidence, Partnerships and People are applied as the lens in explaining the application of Big Data in contemporary marketing practice. Big Data is already guiding marketing decision-making at multiple levels, from analysing consumer buying behaviour to Internet-of-Things (IoT)-enabled devices that report on product use conditions, service requirements or processing data from manufacturing. In the future, Artificial Intelligence will become important in handling Big Data. In preparation for this, the…
Efficiency of temporal sensor data compression methods to reduce LoRa-based sensor node energy consumption
2022
Purpose Minimizing the energy consumption in a wireless sensor node is important for lengthening the lifetime of a battery. Radio transmission is the most energy-consuming task in a wireless sensor node, and by compressing the sensor data in the online mode, it is possible to reduce the number of transmission periods. This study aims to demonstrate that temporal compression methods present an effective method for lengthening the lifetime of a battery-powered wireless sensor node. Design/methodology/approach In this study, the energy consumption of LoRa-based sensor node was evaluated and measured. The experiments were conducted with different LoRaWAN data rate parameters, with and without …
