Yksinäisten työikäisten vuorovaikutussuhteet
2018
Riittävät vuorovaikutussuhteet ovat tärkeä hyvinvoinnin resurssi. Vuorovaikutussuhteiden vähäisyys tai se, etteivät suhteet vastaa odotuksia, aiheuttaa ahdistusta ja muita negatiivisia tunteita. On luonnollista tuntea ajoittain itsensä yksinäiseksi, mutta pitkittynyt tai pysyvä yksinäisyyden tunne on vakava ongelma. Tämän systemaattisen kirjallisuuskatsauksen tavoitteena on jäsentää, mitä tiedetään yksinäisten työikäisten vuorovaikutussuhteista. Työikäisillä tarkoitetaan tässä alle 65-vuotiaita aikuisia. Katsaus kohdistuu työikäisten yksinäisyyttä koskevaan viestinnän ja lähitieteiden tutkimukseen vuosilta 2006–2017. Viimeaikainen työikäisten yksinäisyyden tutkimus on kohdistunut yksinäiste…

Una más de la familia. Au pairs atrapadas entre el capital humano y la economía moral
2018
In contemporary societies we are witnessing an expansion of the messages of human capital. These messages have as their central dimension idea of the self-entrepreneur, which implies a deepening in the logic of activation, while blurring the wage relations. In this scenario, young people with university degrees are becoming a favourite target in the offensive of human capital. The penetration of these human capital messages can be seen in the discourses of young university students who have been forced to leave the country during the crisis. In the present text we approach the discourses of young women who came out as au pairs. The characteristics of this figure place it in a space halfway …
Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era
2018
The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…
A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network
2016
The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…
Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
2016
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …
Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna
2017
Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
”Ei elämääni lomia mahtunut.” – Naisten muistelukerrontaa palkkatyöstä talvi- ja jatkosotien ja jälleenrakennuksen aikana
2014
My doctoral dissertation examines women’s memory narratives of paid labour during the Winter War (1939–1940) and the Continuation War (1941–1945, including the Lapland War) and in the years of rebuilding in Finland until early 1950s. As an ethnologist, I am interested in the personal level of everyday life and experiences of work. My main interest lies in the meanings women give to paid labour. The focus is on memory narratives, and I am reaching and I aim to bring to light the meanings given to work: what did paid labour mean for women during the war and the time of rebuilding and how do they tell about it decades afterwards? I analyse, for example, the effect of the war on women’s work ex…
