Letters from the War of Ecosystems – An Analysis of Independent Software Vendors in Mobile Application Marketplaces

The recent emergence of a new generation of mobile application marketplaces has changed the business in the mobile ecosystems. The marketplaces have gathered over a million applications by hundreds of thousands of application developers and publishers. Thus, software ecosystems—consisting of developers, consumers and the orchestrator—have emerged as a part of the mobile ecosystem. This dissertation addresses the new challenges faced by mobile application developers in the new ecosystems through empirical methods. By using the theories of two-sided markets and business ecosystems as the basis, the thesis assesses monetization and value creation in the market as well as the impact of electronic Word-of-Mouth (eWOM) and developer multihoming— i. e. contributing for more than one platform—in the ecosystems. The data for the study was collected with web crawling from the three biggest marketplaces: Apple App Store, Google Play and Windows Phone Store. The dissertation consists of six individual articles. The results of the studies show a gap in monetization among the studied applications, while a majority of applications are produced by small or micro-enterprises. The study finds only weak support for the impact of eWOM on the sales of an application in the studied ecosystem. Finally, the study reveals a clear difference in the multi-homing rates between the top application developers and the rest. This has, as discussed in the thesis, an impact on the future market analyses—it seems that the smart device market can sustain several parallel application marketplaces.Muutama vuosi sitten julkistetut uuden sukupolven mobiilisovellusten kauppapaikat ovat muuttaneet mobiiliekosysteemien liiketoimintadynamiikkaa. Nämä uudet markkinapaikat ovat jo onnistuneet houkuttelemaan yli miljoona sovellusta sadoilta tuhansilta ohjelmistokehittäjiltä. Nämä kehittäjät yhdessä markkinapaikan organisoijan sekä loppukäyttäjien kanssa ovat muodostaneet ohjelmistoekosysteemin osaksi laajempaa mobiiliekosysteemiä. Tässä väitöskirjassa tarkastellaan mobiilisovellusten kehittäjien uudenlaisilla kauppapaikoilla kohtaamia haasteita empiiristen tutkimusmenetelmien kautta. Väitöskirjassa arvioidaan sovellusten monetisaatiota ja arvonluontia sekä verkon asiakasarviointien (engl. electronicWord-of-Mouth, eWOM) ja kehittäjien moniliittymisen (engl. multi-homing) — kehittäjä on sitoutunut useammalle kuin yhdelle ekosysteemille — vaikutuksia ekosysteemissä. Työn teoreettinen tausta rakentuu kaksipuolisten markkinapaikkojen ja liiketoimintaekosysteemien päälle. Tutkimuksen aineisto on kerätty kolmelta suurimmalta mobiilisovellusmarkkinapaikalta: Apple App Storesta, Google Playstä ja Windows Phone Storesta. Tämä artikkeliväitöskirja koostuu kuudesta itsenäisestä tutkimuskäsikirjoituksesta. Artikkelien tulokset osoittavat puutteita monetisaatiossa tutkittujen sovellusten joukossa. Merkittävä osa tarkastelluista sovelluksista on pienten yritysten tai yksittäisten kehittäjien julkaisemia. Tutkimuksessa löydettiin vain heikkoa tukea eWOM:in positiiviselle vaikutukselle sovellusten myyntimäärissä. Työssä myös osoitetaan merkittävä ero menestyneimpien sovelluskehittäjien sekä muiden kehittäjien moniliittymiskäyttäytymisen välillä. Tällä havainnolla on merkitystä tuleville markkina-analyyseille ja sen vaikutuksia on käsitelty työssä. Tulokset esimerkiksi viittaavat siihen, että markkinat pystyisivät ylläpitämään useita kilpailevia kauppapaikkoja.Siirretty Doriast

The state of the art of the blockchain ethics in healthcare: A systematic literature review

Blockchain is a software innovation which is based on a cryptographically secured, decentralised, and distributed storage of data. The technological breakthrough was done as a part of and became familiar through cryptocurrencies, where it is used to openly store currency transactions among its users. Blockchain technology has been since proposed and used in various domains ranging from open contracts to electronic voting—as well as in various purposes in eHealth, medical and well-being applications. However, its usage in these sectors possesses several ethical questions as these environments are full of personal and private patient information. To study the state-of-the-art of the blockchain ethics in healthcare, this study presents a systematic literature study (SLR) on this phenomenon. By collecting the relevant primary studies from Scopus, the results show that the utilisation of blockchain is swiftly maturing with new research and applications published constantly in this domain. However, the ethical discussion related to the use of blockchain technologies is still taking its baby steps in healthcare. Despite a few openings, ethical research is practically non-existing when compared against the full extant literature on the topic. Therefore, remarkable amount of further work is needed to cover the potential ethical questions related to the adoption and use of the technology.Blockchain is a software innovation which is based on a cryptographically secured, decentralised, and distributed storage of data.

The skill gap and polarization of the software labour force: Early signs of the War of Talents between software professionals and how it threatens wellbeing

The demand for high-skill and deep knowledge is a key characteristic for modern-day software business. In addition, the whole impact of information and communication technology (ICT) is seen as a cross-cutting element in different industries. The software industry in Finland is suffering from a severe labour shortage and the estimations of needed labour are ranging from 7,000 to 15,000 software professional. However, despite all development and research done, the question, whether the software companies are requesting more employers or are they looking for more diverse skills, remains unanswered. Furthermore, previously there has little if any discussion, on whose responsibility is to ensure that future software experts have the right kinds of skills and competencies to secure their successful work career. This study focuses on the skill polarization between software professionals, referred to as the ‘War of Talents’ in this study, by using data collected by a survey (n=90) from Finnish software businesses. The results reveal some indication of ongoing skill polarization in the field and its possible impacts are discussed. Furthermore, the potential threatening impacts of the polarization process on the well-being in the information society are observed and reported. In addition, the paper proposes adding skill development applications among the offering of eWellbeing services due to the importance of work-related competencies to the self-image – and therefore also wellbeing – of individuals.The demand for high-skill and deep knowledge is a key characteristic for modern-day software business.

Proceedings of 11th Symposium on Programming Languages and Software Tools and 7th Nordic Workshop on Model Driven Software Engineering

Robert C. Martin presented a software metric for a set of classes i.e. a package. The objective of the package level metric is to identify poorly designed packages. The Martin's metric actually consists of eight metrics which measure a few different characteristics of packages. The metric is widely known, but there is lack of theoretical and empirical evaluation of the Martin’s metric. This paper evaluates the theoretical background of the metric against an evaluation framework and presents an experimental evaluation of five open-source software applications. The theoretical validation reveals a weakness in Martin's definition for cohesion. We propose a modification which is valid according to the evaluation framework.  </div

Sources of value in application ecosystems

Mobile application stores have revolutionised the dynamics of mobile ecosystems. Research onmobile application ecosystems has been significantly driven by data that is focused on the visualisation of an ecosystem's dynamics. This is a valuable step towards understanding the nature of the ecosystems, but it is limited in its explanatory power. Thus, a theory-driven approach is needed to understand the overall dynamics of such systems. This study applies a theoretical framework of value creation in e-business in the context of mobile application ecosystems, with a focus on application developers. A qualitative research strategy is employed in testing operationalisationina sample of developers. The sample comprises 27 application developers from the three leading mobile application ecosystems. The results show that efficiency is the main source of value, products seldom create value through complementarities, and approaches towards lock-in and novelty seem to vary among application developers. The managerial and theoretical implications of such biased value creation in mobile ecosystems are considered. </div

Young mobile users: Radical and individual – Not

The use of mobile phones by youth has stirred a plethora of research in different fields. Literature has analyzed in length the changes and adoption patterns related to the evolving telecommunications industry. This body of knowledge often makes assumptions on the changes in consumer profiles and the value of different features. In this study we take an longitudinal approach by analysing the results of 1&nbsp;928 responses to an online questionnaire conducted in Finland to students of a university in the Spring 2012 and on against the reanalysis of the responses of the Finnish students of upper secondary schools in the Spring 2001 and study on undergraduate students in 2006&ndash;2007. The results indicate that the youth and young adults of Finland, often argued to be an advanced country for mobile services, are surprisingly conservative towards new mobile devices and services. The changes in technology and service offering in a decade, has had a limited impact in attitudes and feature valuation, which sets significant implications to increasing adoption and usage.</span
