    Meillä on kiireellinen tarve keskittyä maailman suurimpiin ongelmiin, jotka eivät ole helppoja ratkaista. Strategioiden ja ratkaisujen on sovittava modernin yhteiskunnan ominaisuuksiin, kuten ennalta-arvaamattomuuteen ja nopeaan muutokseen. Julkisella sektorilla on oma roolinsa näihin suuriin haasteisiin vastaamisessa. Uusi julkinen hallinto -paradigma edistää julkista päätöksentekoa korostaen yhteistyösuhteita ja kumppanuuksia monimutkaisessa yhteiskunnassa sekä yhteiskehittämistä palvelumallina. Väitöskirja tutkii näitä teemoja Suomen sosiaali- ja terveyspalvelujen kontekstissa, jossa muun muassa väestön ikääntyminen, verotulojen väheneminen, yhteiskunnan digitalisaatio ja käyttäjien korkeat odotukset personoiduista palveluista ovat haastaneet järjestelmän kestävyyttä. Sosiaali- ja terveyspalvelut tarjoavat hyvän esimerkin julkisista palveluista, jossa palvelut ovat aineettomia ja yhteisesti tuotettuja, nykyinen järjestelmä on erittäin monimutkainen ja polkuriippuvainen, ja jossa tarvitaan perustavanlaatuista muutosta. Kuitenkin kokeilut yhteiskehitetyistä palveluista ovat olleet hajallaan, ja järjestelmän tasolla olevaa muutosta ei ole tapahtunut. Systeemitasoinen näkemys muutoksesta sekä tällaisen muutoksen edistämistavoista on puuttunut. Tämä väitöskirja tutkii, voiko palveluiden yhteiskehittäminen todella uudistaa sosiaali- ja terveyspalveluja Suomessa perustuen neljään vertaisarvioituun artikkeliin. Tulokset osoittavat, että järjestelmän uudistaminen on mahdollista, mutta vaatii toteutuakseen systeemisiä muutoksia yhteiskehittämisen potentiaalin hyödyntämiseksi. Väitöskirjassa on tunnistettu tarvittavat systeemiset muutokset aiemman kirjallisuuden pohjalta, ja uutta tietoa on tuotettu empiirisessä tutkimuksessa, jotka esitellään artikkeleissa 1 ja 2. Tulokset osoittavat tarpeen edistää oppimista ja ymmärrystä siitä, miten palveluita voidaan yhteiskehittää käyttäjien kanssa. Lisäksi muutosta tulisi ymmärtää useina samanaikaisesti tapahtuvina uudistuksina, joita tulisi tukea pitkäjänteisillä politiikkatoimenpiteillä. Lisäksi väitöskirja tutkii, voiko muutosta kohti yhteiskehittämistä edistää. Tämän kysymyksen ratkaisemiseksi hyödynnettiin transitiotutkimuksen piirissä kehitettyjä teoreettisia ja käytännöllisiä viitekehyksiä monitasomuutoksen mallista (multi-level perspective), systeemisen muutoksen suuntaamisesta (transition management) sekä strategisesta niche-johtamisesta (strategic niche management), ja tutkittiin voisivatko nämä tarjota välineitä muutoksen ymmärtämiseen ja edistämiseen. Transitiotutkimus näkee, että sosiaali- ja terveysjärjestelmä tulisi ymmärtää systeemisestä näkökulmasta joukkona keskenään yhteydessä olevina elementteinä, joiden monimutkainen keskinäinen vuorovaikutus tuottaa järjestelmämuutoksen. Transitio nähdään tapahtuvan, kun toimintaympäristön, toimintajärjestelmän ja niche-tason dynamiikat linkittyvät ja vahvistaa toisiaan. Perustuen artikkeleihin 3 ja 4, väitöskirja toteaa, että Suomen sosiaali- ja terveydenhuollon palveluiden yhteiskehittämistä voitaisiin ymmärtää ja edistää transitiotutkimuksen avulla ja se tarjoaa esimerkkejä ns. kaksoiskehäisen oppimisen edistämisestä ja muutosten vaikutusten arvioinnista poliittisen päätöksenteon tueksi.There is an urgent need to focus on the world’s biggest problems that are not easy to solve. Strategies and solutions need to be designed to fit the characteristics of modern societies, such as unpredictability and rapid change. The public sector has its role in answering the grand challenges. The paradigm of New Public Governance promotes public policymaking, highlighting relationships and partnerships in complex societies and co-creation as the service model. These issues are studied in the context of social and healthcare services in Finland, where the factors such as the aging population, decreased tax revenues, digitalization of society, and high expectations of users toward personalized services have challenged systems’ sustainability. Social and healthcare services provide a good example of a field where the services are intangible and fundamentally co-produced, the current system is highly complex and path dependent, and there is a need for a paradigmatic change. However, experiments in introducing co-creation have been scattered, and a transition toward the use of co-creation in service production on a wider scale has not happened. What has been missing is the systemic view of the change and how it could be promoted. This dissertation studies whether co-creation can truly renew public sector social and healthcare services in Finland and is based on four published peer-reviewed articles. The results show that the system can be reformed, but there is a need for systemic changes to utilize the potential of co-creation. Required systemic changes have been identified from the previous literature, and new knowledge has been produced based on empirical studies that are introduced in Papers 1 and 2. The results indicate the need to promote learning and how to co-create with users, initiate long-term policy actions, and understand change as a constellation of different changes in the system. In addition, the dissertation studies whether the change toward co-creation can be promoted. For this purpose, a research stream of transition studies was included in the dissertation to study whether its theoretical and practical frameworks of multi-level perspective, transition management, and strategic niche management could provide tools to understand and promote the change. Transition studies claim that the social and healthcare system should be understood from the systemic perspective and viewed as a constellation of interconnected elements. Transition is seen to come about when the dynamics at the levels of landscape, regime, and niche level link up and reinforce each other. In the dissertation, it is argued, based on Papers 3 and 4, that co-creation of Finnish social and healthcare services could be understood and promoted by the use of transition studies and provides examples of promoting double-loop learning and supporting policymakers to evaluate the impacts of change

    Anomaly detection through User Behaviour Analysis

    The rise in cyber-attacks and cyber-crime is causing more and more organizations and individuals to consider the correct implementation of their security systems. The consequences of a security breach can be devastating, ranging from loss of public confidence to bankruptcy. Traditional techniques for detecting and stopping malware rely on building a database of known signatures using known samples of malware. However, these techniques are not very effective at detecting zero-day exploits because there are no samples in their malware signature databases. The limitation of not being able to detect zero-day exploits leaves organisations vulnerable to new and evolving malware threats. To address this challenge, this thesis proposes a novel approach to malware detection using machine learning techniques. The proposed approach creates a user profile that trains a machine learning model using only normal user behaviour data, and detects malware by identifying deviations from this profile. In this way, the proposed approach can detect zero-day malware and other previously unknown threats without having a specific database of malware signatures. The proposed approach is evaluated using real-world datasets, and different machine learning algorithms are compared to evaluate their performance in detecting unknown threats. The results show that the proposed approach is effective in detecting malware, achieving high accuracy and low false positive rates. This thesis contributes to the field of malware detection by providing a new perspective and approach that complements existing methods, and has the potential to improve the overall security of organisations and individuals in the face of evolving cybersecurity threats

    seven story building made of shipping containers is planned to be built in Barcelona, Spain. This study mainly aimed to evaluate the fire performance of one of these residential shipping containers whose walls and ceiling will have a shaft wall system installed. The default assembly consisted of three fire resistant gypsum boards for vertical panels and a mineral wool layer within the framing system. This work aimed to assess if system variants (e.g. less gypsum boards, no mineral wool layer) could still be adequate considering fire resistance purposes. To determine if steel temperatures would attain a predetermined temperature of 300-350ºC (a temperature value above which mechanical properties of steel start to change significantly) the temperature evolution within the shaft wall system and the corrugated steel profile of the container was analysed under different fire conditions. Diamonds simulator (v. 2020; Buildsoft) was used to perform the heat transfer analysis from the inside surface of the container (where the fire source was present) and within the shaft wall and the corrugated profile. To do so gas temperatures near the walls and the ceiling were required, so these temperatures were obtained from two sources: (1) The standard fire curve ISO834; (2) CFD simulations performed using the Fire Dynamics Simulator (FDS). Post-flashover fire scenarios were modelled in FDS taking into account the type of fuel present in residential buildings according to international standards. The results obtained indicate that temperatures lower than 350ºC were attained on the ribbed steel sheet under all the tested heat exposure conditions. When changing the assembly by removing the mineral wool layer, fire resistance was found to still be adequate. Therefore, under the tested conditions, the structural response of the containers would comply with fire protection standards, even in the case where insulation was reduced.Postprint (published version
