Value of Information Logistics Integration in Digital Business Ecosystem

Digital business ecosystems (DBE) are becoming an increasingly popular concept for modelling and building distributed systems in heterogeneous, decentralized and open environments. Information- and communication technology (ICT) enabled business solutions have created an opportunity for automated business relations and transactions. The deployment of ICT in business-to-business (B2B) integration seeks to improve competitiveness by establishing real-time information and offering better information visibility to business ecosystem actors. The products, components and raw material flows in supply chains are traditionally studied in logistics research. In this study, we expand the research to cover the processes parallel to the service and information flows as information logistics integration. In this thesis, we show how better integration and automation of information flows enhance the speed of processes and, thus, provide cost savings and other benefits for organizations. Investments in DBE are intended to add value through business automation and are key decisions in building up information logistics integration. Business solutions that build on automation are important sources of value in networks that promote and support business relations and transactions. Value is created through improved productivity and effectiveness when new, more efficient collaboration methods are discovered and integrated into DBE. Organizations, business networks and collaborations, even with competitors, form DBE in which information logistics integration has a significant role as a value driver. However, traditional economic and computing theories do not focus on digital business ecosystems as a separate form of organization, and they do not provide conceptual frameworks that can be used to explore digital business ecosystems as value drivers—combined internal management and external coordination mechanisms for information logistics integration are not the current practice of a company’s strategic process. In this thesis, we have developed and tested a framework to explore the digital business ecosystems developed and a coordination model for digital business ecosystem integration; moreover, we have analysed the value of information logistics integration. The research is based on a case study and on mixed methods, in which we use the Delphi method and Internetbased tools for idea generation and development. We conducted many interviews with key experts, which we recoded, transcribed and coded to find success factors. Qualitative analyses were based on a Monte Carlo simulation, which sought cost savings, and Real Option Valuation, which sought an optimal investment program for the ecosystem level. This study provides valuable knowledge regarding information logistics integration by utilizing a suitable business process information model for collaboration. An information model is based on the business process scenarios and on detailed transactions for the mapping and automation of product, service and information flows. The research results illustrate the current cap of understanding information logistics integration in a digital business ecosystem. Based on success factors, we were able to illustrate how specific coordination mechanisms related to network management and orchestration could be designed. We also pointed out the potential of information logistics integration in value creation. With the help of global standardization experts, we utilized the design of the core information model for B2B integration. We built this quantitative analysis by using the Monte Carlo-based simulation model and the Real Option Value model. This research covers relevant new research disciplines, such as information logistics integration and digital business ecosystems, in which the current literature needs to be improved. This research was executed by high-level experts and managers responsible for global business network B2B integration. However, the research was dominated by one industry domain, and therefore a more comprehensive exploration should be undertaken to cover a larger population of business sectors. Based on this research, the new quantitative survey could provide new possibilities to examine information logistics integration in digital business ecosystems. The value activities indicate that further studies should continue, especially with regard to the collaboration issues on integration, focusing on a user-centric approach. We should better understand how real-time information supports customer value creation by imbedding the information into the lifetime value of products and services. The aim of this research was to build competitive advantage through B2B integration to support a real-time economy. For practitioners, this research created several tools and concepts to improve value activities, information logistics integration design and management and orchestration models. Based on the results, the companies were able to better understand the formulation of the digital business ecosystem and the importance of joint efforts in collaboration. However, the challenge of incorporating this new knowledge into strategic processes in a multi-stakeholder environment remains. This challenge has been noted, and new projects have been established in pursuit of a real-time economy.

To Divide or Not to Divide; MicroRNAs and Small Compounds as Modulators of Mitosis

Mitosis is under the stringent quality control of the spindle assembly checkpoint (SAC). However, in cancer cells this control can fail, leading to excessive cellular proliferation and ultimately to the formation of a tumor. Novel cancer cell selective therapies are needed to stop the uncontrolled cell proliferation and tumor growth. The aim of the research presented in this thesis was to identify microRNAs (miRNAs) that could play a role in cancer cell proliferation as well as low molecular weight (LMW) compounds that could interfere with cell division. The findings could be used to develop better cancer diagnostics and therapies in the future. First, a high-throughput screen (HTS) was performed to identify LMW compounds that possess a similar chemical interaction field as rigosertib, an anti-cancer compound undergoing clinical trials. A compound termed Centmitor-1 was discovered that phenocopied the cellular impact of rigosertib by affecting the microtubule dynamics. Next, another HTS aimed at identifying compounds that would target the Hec1 protein, which mediates the interaction between spindle microtubules and chromosomes. Perturbation of this connection should prevent cell division and induce cell death. A compound termed VTT-006 was discovered that abrogated mitosis in several cell line models and exhibited binding to Hec1 in vitro. Lastly, using a cell-based HTS two miRNAs were identified that affected cancer cell proliferation via Aurora B kinase, which is an important mitotic regulator. MiR-378a-5p was found to indirectly suppress the production of the kinase whereas let-7b showed direct binding to the 3’UTR of Aurora B mRNA and repressed its translation. The miRNA-mediated perturbation of Aurora B induced defects in mitosis leading to abnormal chromosome segregation and induction of aneuploidy. The results of this thesis provide new information on miRNA signaling in cancer, which could be utilized for diagnostic purposes. Moreover, the thesis introduces two small compounds that may benefit future drug research.

MARKETING COMMUNICATIONS IN B2B COMPANIES – The Roles of Marketing Communication Tools in the Digital Age

Marketing communications has gone through significant changes during the last decades and new online tools have been leading this change for the last decade. Now, in the digital age, if wanting to be successful companies need to experiment new things and seize the opportunities online provides and adapt to the new environment. However, during this time the marketing communication mix and the meanings given to the various components of it have not changed dramatically, and personal selling, direct marketing, sales promotion, advertising and public relations activities are still regarded as important tools in the marketing communications mix. The purpose of this study was to examine business-to-business marketing communications and the tools used by companies in their marketing communications efforts in the digital age and in a global environment. The research questions dealt with the marketing communication tools and their roles as well as the role of online marketing communication and the way it has shaped the field of b2b marketing communications. In order to answer these questions, qualitative approach was chosen and the data was collected by theme interviews with six representatives of Finnish global companies from the b2b sector being interviewed. The theoretical framework covers the general field of b2b marketing communications and its main elements. The online environment as well as the concept of a global marketplace and integrated approach to marketing communication activities is also discussed. The theory was supported by the interviews regarding the activities and roles of the marketing communication tools and both theory as well as the interviews found personal selling to be a vital tool. However, the importance of online has grown and online marketing activities have risen right next to personal selling. The use of analytics and marketing automation was found to be of great interest in the interviews and they were seen as a growing domain in b2b marketing communications. The importance of targeted and personalised messages from relevant medias was a repeating theme as was the customer-centric approach in marketing communication activities. Also, offline and online tools and channels were seen as something that should be treated together as an entity rather than as separate activities. Relevant content created according to the needs of the customer with the gathered data from analytics were seen as the future of b2b marketing communications. Online has added its input to the more traditionally perceived tools and they are executed within the framework of the digital age. Nevertheless, even though online has increased its presence in the b2b marketing communications mix, the more traditionally perceived marketing communication tools, especially personal selling, have not lost their meaning or place in the b2b marketing communication mix.

Digital Humanities For Everyone’s Benefit?: interplay in social media with the great audience, high-esteemed researcher and self-conscious library

The National Library of Finland realizes the Digitization Project of Kindred Languages in 2012–15. The project is financially supported by the Kone Foundation. During this project the National Library of Finland has digitized and made available approximately 1200 monograph and more than 100 newspaper titles in several Uralic languages. The materials are available to both researchers and citizens in the National Library’s Fenno-Ugrica collection. The project will produce digitized materials in the Uralic languages as well as their development tools to support linguistic research and citizen science. The resulting materials will constitute the largest resource for the Uralic languages in the world. Through this project, researchers will gain access to corpora which they have not been able to study before and to which all users will have open access regardless of their place of residence. In my presentation, I will discuss 1) how we utilized the social media (Facebook, Twitter, VKontakte etc) to gain audience for our collection and 2) how the needs of researchers and laymen were met in crowdsourcing.

Den digitala musikläraren : aktionsforskning om en digital lärmiljö i musikundervisning

Avhandlingens syfte är att ta reda på hur en digital lärmiljö kan fungera som ett didaktiskt komplement vid undervisning av ett instrument under skolans musiklektioner. Genom att observera den egna undervisningen i musik i en skolklass där en digital lärmiljö använts har jag lyft fram iakttagelser av händelser som anses kritiska för utvärderingen av lärmiljön. Undersökningen är av kvalitativ karaktär där aktionsforskning legat som ansats för avhandlingen. Aktionsforskning bygger på att finna ett fokusområde för undersökning, varefter en fråga eller problemformulering utarbetas. Frågan prövas i praktiken och efter det följer en utvärdering och reflektion kring kritiska händelser som observerats i praktiken. En skolklass bestående av elever i årskurserna 3 och 4 har fungerat som respondenter för undersökningen. En del av eleverna i klassen har arbetat individuellt och försökt lära sig spela gitarr och elbas med hjälp av en digital lärmiljö som jag kallar för Musikskolan.fi. Genom att pröva och utvärdera lärmiljön under tre lektioner med eleverna har styrkor, svagheter och differentiering i användandet av Musikskolan.fi diskuterats. För att dokumentera lektionerna har videokamera använts som komplement till forskarens personliga observationer. Enligt de tolkningar och observationer som framkommit i denna undersökning kan Musikskolan.fi fungera bra som stöd och komplement till musikundervisningen, trots att en del förbättringsförslag angående interaktivitet och differentiering noterats. Lärmiljöns styrkor ligger i att elever kan arbeta individuellt med läromedlet och ett instrument. Dessutom kan läraren använda sig av verktyget för att ackompanjera eleverna i sång och spel. En av nackdelarna är att det krävs en hel del förkunskaper om musikteori och visuell tolkningsförmåga av eleven för att han eller hon ska kunna utnyttja verktyget till dess fulla potential. Genom tillägg av fler funktioner, som möjligheten att justera tempo på musiken som verktyget spelar upp, kunde lärmiljön bättre stöda elevers skillnader i färdigheter och bidra positivt till differentiering av musikundervisningen.

Lean Methods and Digital Technologies in Healtchare

The experiences of several healthcare organizations were considered to distinguish the most frequently used lean tools, the success and failure factors, and the obstacles that may appear while implementing lean. As a result, two approaches to “go lean” were defined, and analyzed from the prospective of the applicability to healthcare processes. Industrialization of healthcare was studied, and the most promising digital technology tools to improve healthcare process were highlighted. Finally, the analysis of healthcare challenges and feasible ways to address them was conducted and presented as the main result of this work. The possible ways of implementation of the findings and limitations were described in the conclusion.

To divide or differentiate? : nestin-mediated regulation of Cdk5 in cell fate decisions

The molecular functions of the non-cell cycle-related Cyclin-dependent kinase 5 (Cdk5) have been of primary interest within the neuroscience field, but novel undertakings are constantly emerging for the kinase in tissue homeostasis, as well as in diseases such as diabetes and cancer. Although Cdk5 activation is predominantly regulated by specific non-cyclin activator protein binding, additional mechanisms have proved to orchestrate Cdk5 signaling in cells. For example, the interaction between the intermediate filament protein nestin and Cdk5 has been proposed to determine cellular fate during neuronal apoptosis through nestin-dependent adjustment of the sensitive balance and turnover of Cdk5 activators. While nestin constitutes a crucial regulatory scaffold for appropriate Cdk5 activation in apoptosis, Cdk5 itself phosphorylates nestin with the consequence of filament reorganization in both neuronal progenitors and differentiating muscle cells. Interestingly, the two proteins are often found coexpressed in various tissues and cell types, proposing that nestin-mediated scaffolding of Cdk5 and its activators may be applicable to other tissue systems as well. In the literature, the molecular functions of nestin have remained in the shade, as it is mostly exploited as a marker protein for progenitor cells. In light of these studies, the aim of this thesis was to assess the importance of the nestin scaffold in regulation of Cdk5 actions in cell fate decisions. This thesis can be subdivided into two major projects: one that studied the nature of the Cdk5-nestin interplay in muscle, and one that assessed their role in prostate cancer. During differentiation of a myoblast cell line, the filament formation properties of nestin was found to be crucial in directing Cdk5 activity, with direct consequences on the process of differentiation. Also the genetic knockout of nestin was found to influence Cdk5 activity, although differentiation per se was not affected. Instead, the genetic ablation of nestin had broad consequences on muscle homeostasis and regeneration. While the nestin-mediated regulation of Cdk5 in muscle was found to act in multiple ways, the connection remained more elusive in cancer models. Cdk5 was, however, established as a significant determinant of prostate cancer proliferation; a behavior uncharacteristic for this differentiation-associated kinase. Through complex and simultaneous regulation of two major prostate cancer pathways, Cdk5 was placed upstream of both Akt kinase and the androgen receptor. Its action on proliferation was nonetheless mainly exerted through the Akt signaling pathway in various cancer models. In summary, this thesis contributed to the knowledge of Cdk5 regulation and functions in two atypical settings; proliferation (in a cancer framework) and muscle differentiation, which is a poorly understood model system in the Cdk5 field. This balance between proliferation and differentiation implemented by Cdk5 is ultimately regulated (where present) by the dynamics of the cytoskeletal nestin scaffold.

Visuell läsning som kompetensområde : en pedagogisk studie i visuell grammatik inom multimodal digital kommunikation

Avhandlingens primära syfte är att upprätta en förståelse för visuell kompetens som en del av visuell litteracitet inom multimodal digital kommunikation i undervisningen. Avhandlingens sekundära syfte är att ur ett pedagogiskt perspektiv lyfta fram visuell litteracitet och visuell kompetens i multimodala diskussioner kring digital pedagogik. Forskningen är kvalitativ och har både teoretisk och empirisk förankring. Den empiriska studien har en fenomenologisk metodansats. Visuell kompetens innebär att visuell läsning behärskas, vilket förutsätter fungerande vokabulär, kritiskt förhållningssätt och kunskaper i läsning och tolkning och användning av bilder. Den visuella grammatikteorin innefattar bildens syntax och semantik. Bilden är ett kontextbundet fenomen, där kontexten berör sociala aspekter, bildens fysiska omgivning samt innehåll. Det empiriska resultatet är att visuell inverkan i undervisningen präglar förberedelser och lektionsmål, berör visuell kommunikationskompetens, inkluderar visuella element som verktyg, strävar involvera flera element i inlärningen och strävar efter att undvika passiva demonstrationer som undervisningsmetod. Bilder behövs som kommunikativt stöd, som inlärningsmetod och som en del i aktivitetspedagogisk undervisning. Genom stöd från läraren kan barnet nå visuell litteracitet som ett kompetensmål, vilket kan ske genom multimodal undervisning.
