Strategiamenetelmän hyödyntäminen huonekaluliiketoiminnan kehittämisessä

Strategia on yrityksen toiminnan perusta. Perinteisillä toimialoilla ei välttämättä nähdä tavoitteellisen strategian tarpeellisuutta ja tärkeä strategiasuunnittelu jää toissijaiseksi. Löytämällä erottuva strategia omaa yritys kilpailuedun. Sinisen meren strategia on teoreettinen viitekehys luoda erilaistavaa liiketoimintaa. Strategian avulla voidaan tunnistaa ja luoda strategiaprofiili uudelle liiketoiminnalle jossa kilpailu ei tehnyt toiminnasta liian haavoittuvaista. Tämä nykytilanteen analysointiin ja siitä erilaistumiseen perustuva muutos voi liittyä itse tuotteeseen tai palveluun, sen tuotteistamiseen tai tuotteen jakelutien uudelleenasemointiin. Strategiatyön tarpeellisuus huonekalujen valmistamisessa ja myynnissä on muuttuvassa tilanteessa avainasemassa. Korkea valmistamisen kustannustaso ei mahdollista kilpailua edullisien tuontituotteiden kanssa ja korkeamman hintatason tuotteilla on toisaalta rajattu ostajakunta sisämarkkinoilla. Monelle toimijalle vientityön aloittaminen on riskialtis kustannuserä. Huonekaluteollisuudessa ja –jakeluteissä on ylikapasiteettia suhteessa kannattavaan liiketoimintaan. Erilaistavina markkinatekijöinä on pidetty hintaa molemmissa ääripäissä, laatua ja designiä. Hyvän jakelutien omaavat yritykset ovat hoitaneet valtakunnallisen myynnin karsien pienet toimijat alalta. Valmistuksessa innovatiivisuus perustuu lähinnä tehokkaaseen tuotantotekniikkaan, mikä osaltaan on nostanut investointien tasoa ja toteutuksen mielekkyyttä. Tuotteena huonekalu on kuitenkin teknisiltä ominaisuuksiltaan yleensä matala ja jo pienellä pääomalla on aloitettavissa tuotannollinen toiminta, mutta tällöin ei menestytä välttämättä tuottavuudessa. Uusina tekijöinä kompleksisessa tilanteessa on nähtävissä voimakkaasti tulossa oleva ympäristöarvojen suurempi huomioiminen. Näistä elementeistä voidaan etsiä strategiaprofiilin avulla uusia markkinarajapintoja, joissa kilpailutilanne mahdollistaa kannattavan liiketoiminnan. Työssä tutkitaan strategiamenetelmän hyödyntämismahdollisuutta, sen perusteita ja tarpeellisuutta perinteisen muutosjäykän teollisuudenalan ja kilpailtujen huonekalumarkkinoiden segmentissä. Uuden toimintamallin tarpeen, strategian, ymmärtämiseksi on tiedostettava ympäristössä tapahtuneet muutokset ja kartoitettava nykyinen strategiaprofiili. Tähän liittyen läpikäydään ne seikat jotka ovat aiheuttaneet nykytilanteen ja näin muutostarpeen tässä markkinassa.

A Headspace needle-trap method for the analysis of volatile organic compounds in whole blood

Needle trap devices (NTDs) are a relatively new and promising tool for headspace (HS) analysis. In this study, a dynamic HS sampling procedure is evaluated for the determination of volatile organic compounds (VOCs) in whole blood samples. A full factorial design was used to evaluate the influence of the number of cycles and incubation time and it is demonstrated that the controlling factor in the process is the number of cycles. A mathematical model can be used to determine the most appropriate number of cycles required to adsorb a prefixed amount of VOCs present in the HS phase whenever quantitative adsorption is reached in each cycle. Matrix effect is of great importance when complex biological samples, such as blood, are analyzed. The evaluation of the salting out effect showed a significant improvement in the volatilization of VOCs to the HS in this type of matrices. Moreover, a 1:4 (blood:water) dilution is required to obtain quantitative recoveries of the target analytes when external calibration is used. The method developed gives detection limits in the 0.020–0.080 μg L−1 range (0.1–0.4 μg L−1 range for undiluted blood samples) with appropriate repeatability values (RSD < 15% at high level and <23% at LOQ level). Figure of merits of the method can be improved by using a smaller phase ratio (i.e., an increase in the blood volume and a decrease in the HS volume), which lead to lower detection limits, better repeatability values and greater sensibility. Twenty-eight blood samples have been evaluated with the proposed method and the results agree with those indicated in other studies. Benzene was the only target compound that gave significant differences between blood levels detected in volunteer non-smokers and smokers

Efeito da associação do herbicida clomazone a nanoesferas de alginato/quitosana na sorção em solos

Agrochemicals constitute the class of products most commonly found in water resources. Their high level of concentration is due to the fact that less than 0.1% of pesticides applied to crops reach their target. The present work aims to study the sorption of clomazone herbicide (associated or not with nanoparticles). The sorption tests, performed with the 2(4) factorial design, showed that the form of herbicide is the main factor for sorption of clomazone. The application of nanoparticles as delivery system for agrochemicals is a pressing area of study and can contribute for decrease in effects of clomazone in the environment.

Managing regulatory risks when outsourcing network-related services in the electricity distribution sector

Deregulation of the electricity sector liberated the electricity sale and production for competitive forces while in the network business, electricity transmission and distribution, natural monopoly positions were recognised. Deregulation was accompanied by efficiencyoriented thinking on the whole electricity supply industry. For electricity distribution this meant a transition from a public service towards profit-driven business guided by economic regulation. Regulation is the primary means to enforce societal and other goals in the regulated monopoly sector. The design of economic regulation is concerned with two main attributes; end-customer price and quality of electricity distribution services. Regulation limits the costs of the regulated company but also defines the desired quality of monopoly services. The characteristics of the regulatory framework and the incentives it provides are therefore decisive for the electricity distribution sector. Regulation is not a static factor; changes in the regulatory practices cause discontinuity points, which in turn generate risks. A variety of social and environmental concerns together with technological advancements have emphasised the relevance of quality regulation, which is expected to lead to the large-scale replacement of overhead lines with underground cables. The electricity network construction activity is therefore currently witnessing revolutionary changes in its competitive landscape. In a business characterised by high statutory involvement and a high level of sunk costs, recognising and understanding the regulatory risks becomes a key success factor. As a response, electricity distribution companies have turned into outsourcing to attain efficiency and quality goals. This doctoral thesis addresses the impacts of regulatory risks on electricity network construction, which is a commonly outsourced activity in the electricity distribution network sector. The chosen research approach is characterised as an action analytical research on account of the fact that regulatory risks are greatly dependent on the individual nature of the regulatory regime applied in the electricity distribution sector. The main contribution of this doctoral thesis is to develop a concept for recognising and managing the business risks stemming from economic regulation. The degree of outsourcing in the sector is expected to increase in years to come. The results of the research provide new knowledge to manage the regulatory risks when outsourcing services.

Assessment of Coals from Russia and Countries of Former Soviet Union for Utility Fluidized Bed Boilers

With the occurrence of fossil fuels such as oil, gas and coal we found new sources of energy that have played a critical role in the progress of our modern society. Coal is very ample compared to the other two fossil fuels. Global coal reserves at the end of 2005 were estimated at 847,5 billion tones. Along with the major energy sources, coal is the most fast growing fuel on a global basis, it provides 26% of primary energy needs and remains essential to the economies of many developed and developing countries. Coal-fired power generation accounts for 41% of the world‘s total electricity production and in some countries, such as South Africa, Poland, China, Australia, Kazakhstan and India is on very high level. Still, coal utilization represents challenges related to high emissions of air pollutants such as sulphur and nitrogen dioxides, particulate matter, mercury and carbon dioxide. In relation to these a number of technologies have been developed and are in marketable use, with further potential developments towards ―Near Zero Emission‖ coal plants. In present work, coals mined in Russia and countries of Former Soviet Union were reviewed. Distribution of coal reserves on the territory of Russia and the potential for power generation from coal-fired plants across Russia was shown. Physical and chemical properties of coals produced were listed and examined, as main factor influencing on design of the combustion facility and incineration process performance. The ash-related problems in coal-fired boilers were described. The analysis of coal ash of Russia and countries of Former Soviet Union were prepared. Feasible combustion technologies also were reviewed.

Methods for construction and analysis of computational models in systems biology : applications to the modelling of the heat shock response and the self-assembly of intermediate filaments

Systems biology is a new, emerging and rapidly developing, multidisciplinary research field that aims to study biochemical and biological systems from a holistic perspective, with the goal of providing a comprehensive, system- level understanding of cellular behaviour. In this way, it addresses one of the greatest challenges faced by contemporary biology, which is to compre- hend the function of complex biological systems. Systems biology combines various methods that originate from scientific disciplines such as molecu- lar biology, chemistry, engineering sciences, mathematics, computer science and systems theory. Systems biology, unlike “traditional” biology, focuses on high-level concepts such as: network, component, robustness, efficiency, control, regulation, hierarchical design, synchronization, concurrency, and many others. The very terminology of systems biology is “foreign” to “tra- ditional” biology, marks its drastic shift in the research paradigm and it indicates close linkage of systems biology to computer science. One of the basic tools utilized in systems biology is the mathematical modelling of life processes tightly linked to experimental practice. The stud- ies contained in this thesis revolve around a number of challenges commonly encountered in the computational modelling in systems biology. The re- search comprises of the development and application of a broad range of methods originating in the fields of computer science and mathematics for construction and analysis of computational models in systems biology. In particular, the performed research is setup in the context of two biolog- ical phenomena chosen as modelling case studies: 1) the eukaryotic heat shock response and 2) the in vitro self-assembly of intermediate filaments, one of the main constituents of the cytoskeleton. The range of presented approaches spans from heuristic, through numerical and statistical to ana- lytical methods applied in the effort to formally describe and analyse the two biological processes. We notice however, that although applied to cer- tain case studies, the presented methods are not limited to them and can be utilized in the analysis of other biological mechanisms as well as com- plex systems in general. The full range of developed and applied modelling techniques as well as model analysis methodologies constitutes a rich mod- elling framework. Moreover, the presentation of the developed methods, their application to the two case studies and the discussions concerning their potentials and limitations point to the difficulties and challenges one encounters in computational modelling of biological systems. The problems of model identifiability, model comparison, model refinement, model inte- gration and extension, choice of the proper modelling framework and level of abstraction, or the choice of the proper scope of the model run through this thesis.

”Jos tietää, mitä haluaa.” Seurantatutkimus lukio-opiskelijoiden itsesäätelystä, opiskelun kulusta ja odotusten toteutumisesta

Tutkimuksen päätarkoituksena on selvittää lukio-opiskelijoiden käsityksiä oppimisensa itsesäätelystrategioista. Lukiokoulutuksessa toteutetut muutokset kuten valinnanmahdollisuuksien lisääntyminen ovat antaneet lukio-opiskelijoille kasvaneen mahdollisuuden omanlaisensa lukio-opiskelupolun suunnitteluun ja yksilölliseen tavoitteenasetteluun. Työssä tarkastellaan myös lukio-opiskelijoiden opintojen kulkua, erilaisia opiskeluodotuksia ja niiden toteutumista sekä näiden yhteyttä itsesäätelyyn. Tutkimus toteutettiin seurantatutkimuksena, jossa kyselylomakkeilla kerättiin tietoa syksyllä 2004 Turun kaupungin suomenkielisissä päivälukioissa (10 koulua) opintonsa aloittavilta opiskelijoilta kahdesti; ensimmäisenä ja kolmantena opiskeluvuotena. Tutkimuksessa oli mukana 245 opiskelijaa, 142 tyttöä ja 103 poikaa. Tutkimuksen vastausprosentti oli 84 %. Kyselylomakkeiden itsesäätelyä ja oppimisorientaatioita koskevat kysymykset pohjautuivat Jan Vermuntin ILS-oppimistyylimittariin (Inventory of Learning Styles) (Vermunt 1994; 1996). Lisäksi haastateltiin 15 tutkimuksessa mukana ollutta opiskelijaa. Kyselylomakeaineisto analysoitiin ristiintaulukoinneilla, korrelaatiokertoimilla, t-testeillä ja erilaisilla varianssianalyyseillä. Itsesäätelystrategiamittarin neljän summamuuttujan oletus testattiin erikseen mittauksissa 1 ja 2 konfirmatorisen faktorianalyysin avulla. Tutkimuksessa identifioitiin klusterianalyysillä tehdyssä ryhmittelyssä neljä erilaista lukio-opiskelijaryhmää: menestyvät navigoijat, tavalliset tasapainoilijat, säätelemättömät kulkeutujat ja ylikuormittuneet avuntarvitsijat. Navigoijille on tyypillistä niin prosessin/ tulosten kuin sisällön suhteen korkea itsesäätely. Tyypillinen piirre navigoijien kohdalla on myös ulkoisen säätelyn korkea taso. Avuntarvitsijat eroavat muista ryhmistä selkeästi korkeampien puutteellisten säätelystrategioidensa perusteella, vaikka heidän itsesäätelynsä on suhteellisesti niihin ja muihin ryhmiin nähden melko korkealla tasolla. Tasapainoilijat sijoittuvat itsesäätelyn ja ulkoisen säätelyn osalta ryhmien keskitasolle. Kulkeutujien itsesäätely samoin kuin ulkoinen säätely ovat ryhmien matalinta tasoa. Tuloksista nähdään, että kehittyneemmällä itsesäätelyllä on selvä yhteys lukio-opintojen sujuvuuteen ja opintomenestykseen, mutta noin kolmasosalle opiskelijoista itsesäätelevä, suunnitelmallinen tavoitteenasettelu on vaikeaa. Navigoijilla ja tasapainoilijoilla opiskelu on sekä heille itselleen mielekästä että ulkoisesti arvioituna tehokasta. Joidenkin opiskelijoiden erityisesti avuntarvitsijoiden ja kulkeutujien keskuudessa opintojen kulku sen sijaan hapuilee. Lukiolaisten opiskeluun kohdistuvien odotusten voidaan tämän tutkimuksen tuloksen perusteella katsoa ennustavan todellista opintojen kulkua ja opintomenestystä melko hyvin. Eroja on sekä tavoitetasossa, opiskeluprosessiin liittyvissä kokemuksissa että jatko-opintosuunnitelmissa ja ne ovat yhteydessä sukupuoleen, isän sosioekonomiseen asemaan, erikoislinjalla opiskeluun sekä lukion alun itsesäätelyryhmiin.

Ydinvoimalaitoksen rakentamisen aikainen viranomaistoiminta ja -vaatimukset

Tässä diplomityössä on käsitelty ydinvoimalaitoksen rakentamisprosessin aikaista viran-omaistoimintaa, viranomaisten vaatimuksia sekä rakentamiseen liittyvää riskienhallintaa julkisesti saatavissa olevan materiaalin pohjalta. Ensin on käyty läpi johdannon ja tavoitteiden lisäksi ydinvoiman historiaa ja nykyhetkeä Suomessa. Tämän jälkeen työssä on käsitelty riskienhallintaa sekä siihen liittyvää yleistä teoriaa. Teoria toimii lisätukena viranomaisvaatimusten tarkastelussa sekä niiden toimien ymmärtämisessä. Ennen viranomaisvaatimuksia on tarkasteltu kuitenkin itse viranomaisia, niiden välisiä kytköksiä sekä sitä, mitkä eri viranomaiset vaikuttavat ydinvoimalaitoksen rakentamiseen. Tässä osiossa on tarkasteltu myös politiikan vaikutusta viranomaistoimintaan. Viranomaisten toimintaa ja vaatimuksia käsittelevässä osiossa on käyty läpi yleisesti ydinvoimalaitokseen liittyviin toimituksiin kuuluvat vaatimukset sekä yksityiskohtaisempia vaatimuksia aihealueittain. Tässä osiossa on myös käsitelty esimerkkejä Olkiluoto 3 –projektissa tehdyistä havainnoista ja toteutuneista riskeistä. Tämän jälkeen työssä on tehty tarvittavat johtopäätökset tutkimuskysymyksiin läpikäydyn materiaalin pohjalta. Johtopäätöksissä on myös käsitelty ydinvoimalaitokseen liittyvään toimitukseen sisältyviä riskejä sekä niiden hallintaa. Viranomaistyöstä korostuivat läpikäydyssä materiaalissa erityisesti suomalaisen viranomaistoiminnan tinkimättömyys ja korkea vaatimustaso. Tärkeimmiksi seikoiksi työssä nousivat ydinvoimalaitoksen rakentamiseen olennaisena osana kuuluva korkea turvallisuuskulttuuri sekä sen seurauksena yritysten toimivat johtamisjärjestelmät. Lisäksi hyvin tehty esi- ja perussuunnittelu helpottavat projektin eri osa-alueita. Huomioimalla nämä kolme seikkaa pystytään ydinvoimalaitoksen rakentamisen ja käytön aikaisia riskejä hallitsemaan tehokkaimmalla tavalla.

Design Space Exploration for MPSoC Architectures

Multiprocessor system-on-chip (MPSoC) designs utilize the available technology and communication architectures to meet the requirements of the upcoming applications. In MPSoC, the communication platform is both the key enabler, as well as the key differentiator for realizing efficient MPSoCs. It provides product differentiation to meet a diverse, multi-dimensional set of design constraints, including performance, power, energy, reconfigurability, scalability, cost, reliability and time-to-market. The communication resources of a single interconnection platform cannot be fully utilized by all kind of applications, such as the availability of higher communication bandwidth for computation but not data intensive applications is often unfeasible in the practical implementation. This thesis aims to perform the architecture-level design space exploration towards efficient and scalable resource utilization for MPSoC communication architecture. In order to meet the performance requirements within the design constraints, careful selection of MPSoC communication platform, resource aware partitioning and mapping of the application play important role. To enhance the utilization of communication resources, variety of techniques such as resource sharing, multicast to avoid re-transmission of identical data, and adaptive routing can be used. For implementation, these techniques should be customized according to the platform architecture. To address the resource utilization of MPSoC communication platforms, variety of architectures with different design parameters and performance levels, namely Segmented bus (SegBus), Network-on-Chip (NoC) and Three-Dimensional NoC (3D-NoC), are selected. Average packet latency and power consumption are the evaluation parameters for the proposed techniques. In conventional computing architectures, fault on a component makes the connected fault-free components inoperative. Resource sharing approach can utilize the fault-free components to retain the system performance by reducing the impact of faults. Design space exploration also guides to narrow down the selection of MPSoC architecture, which can meet the performance requirements with design constraints.

Reframing the relationship between service design and operations: a service engineering approach

The significance of services as business and human activities has increased dramatically throughout the world in the last three decades. Becoming a more and more competitive and efficient service provider while still being able to provide unique value opportunities for customers requires new knowledge and ideas. Part of this knowledge is created and utilized in daily activities in every service organization, but not all of it, and therefore an emerging phenomenon in the service context is information awareness. Terms like big data and Internet of things are not only modern buzz-words but they are also describing urgent requirements for a new type of competences and solutions. When the amount of information increases and the systems processing information become more efficient and intelligent, it is the human understanding and objectives that may get separated from the automated processes and technological innovations. This is an important challenge and the core driver for this dissertation: What kind of information is created, possessed and utilized in the service context, and even more importantly, what information exists but is not acknowledged or used? In this dissertation the focus is on the relationship between service design and service operations. Reframing this relationship refers to viewing the service system from the architectural perspective. The selected perspective allows analysing the relationship between design activities and operational activities as an information system while maintaining the tight connection to existing service research contributions and approaches. This type of an innovative approach is supported by research methodology that relies on design science theory. The methodological process supports the construction of a new design artifact based on existing theoretical knowledge, creation of new innovations and testing the design artifact components in real service contexts. The relationship between design and operations is analysed in the health care and social care service systems. The existing contributions in service research tend to abstract services and service systems as value creation, working or interactive systems. This dissertation adds an important information processing system perspective to the research. The main contribution focuses on the following argument: Only part of the service information system is automated and computerized, whereas a significant part of information processing is embedded in human activities, communication and ad-hoc reactions. The results indicate that the relationship between service design and service operations is more complex and dynamic than the existing scientific and managerial models tend to view it. Both activities create, utilize, mix and share information, making service information management a necessary but relatively unknown managerial task. On the architectural level, service system -specific elements seem to disappear, but access to more general information elements and processes can be found. While this dissertation focuses on conceptual-level design artifact construction, the results provide also very practical implications for service providers. Personal, visual and hidden activities of service, and more importantly all changes that take place in any service system have also an information dimension. Making this information dimension visual and prioritizing the processed information based on service dimensions is likely to provide new opportunities to increase activities and provide a new type of service potential for customers.

Reduction of seed production of red rice escapes in clearfield rice

Roguing is a practice used to reduce the seed source of red rice escapes to control in Clearfield-rice areas. However, there is great difficulty in performing it in large and heavily infested rice fields. This objective of this work was to evaluate the effects of the use of imazamox herbicide, applied in different rates and times, on plants of Clearfield-rice and red rice. Four experiments were conducted during the 2007/08 and 2008/09 growing seasons, in completely randomized block design and treatments arranged in factorial design, using three replications per treatment. The treatments had increasing rates of imazamox, application times and rice cultivars. The rice cultivars tested were IRGA 417, IRGA 422 CL, Avaxi CL and Puitá INTA CL. The variables evaluated were the number of panicles m-2, number of grains panicle-1, spikelet sterility in rice and red rice; and, rice grain yield and its components. The imazamox reduced the seed production of red rice escapes in a simulated situation of commercial Clearfield-rice area. The greater percentage reductions were obtained when this herbicide was applied at final formation of the panicle or panicle exertion of the red rice plant escapes to control. The Puitá INTA CL cultivar has high level of resistance to imazamox, independent of rate and application times tested, becoming the only alternative to the use of this practice.

Resistance of Raphanus raphanistrum to the herbicide metsulfuron-methyl

The ALS-inhibiting herbicides, especially metsulfuron-methyl, are widely used for weed control, mainly wheat and barley in southern Brazil. Raphanus raphanistrum is a major weed of winter crops. However, in recent years, R.raphanistrum, after being treated with metsulfuron, has shown no symptoms of toxicity, possibly due to herbicide resistance. Aiming to evaluate the existence of R.raphanistrum biotypes resistant to metsulfuron, an experiment was conducted in a greenhouse, in a completely randomized design with four replications. The plots consisted of pots with six plants. The treatments consisted of the interaction of resistant R. raphanistrum (biotype R) and susceptible R. raphanistrum (biotypes S) with ten doses of the herbicide (0.0; 0.6; 1.2; 2.4; 4.8; 9.6; 19.2; 38.4; 76.8 and 153.6 g i.a. ha-1). The application of the test herbicides occurred when the crop was at the stage of 3 to 4 true leaves. The variables analyzed were control and dry matter accumulation. Statistical analysis of dose-response curves was performed by non linear regression. Biotype S was susceptible to the herbicide even at doses below the recommended. Biotype R was insensitive to the herbicide obtaining values of resistance factor (F) higher than 85. The dose-response curve confirmed the existence of R. raphanistrum biotypes with high level of resistance to metsulfuron-methyl.

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.

A high-copy T7 Escherichia coli expression vector for the production of recombinant proteins with a minimal N-terminal His-tagged fusion peptide

We report here the construction of a vector derived from pET3-His and pRSET plasmids for the expression and purification of recombinant proteins in Escherichia coli based on T7 phage RNA polymerase. The resulting pAE plasmid combined the advantages of both vectors: small size (pRSET), expression of a short 6XHis tag at N-terminus (pET3-His) and a high copy number of plasmid (pRSET). The small size of the vector (2.8 kb) and the high copy number/cell (200-250 copies) facilitate the subcloning and sequencing procedures when compared to the pET system (pET3-His, 4.6 kb and 40-50 copies) and also result in high level expression of recombinant proteins (20 mg purified protein/liter of culture). In addition, the vector pAE enables the expression of a fusion protein with a minimal amino-terminal hexa-histidine affinity tag (a tag of 9 amino acids using XhoI restriction enzyme for the 5'cloning site) as in the case of pET3-His plasmid and in contrast to proteins expressed by pRSET plasmids (a tag of 36 amino acids using BamHI restriction enzyme for the 5'cloning site). Thus, although proteins expressed by pRSET plasmids also have a hexa-histidine tag, the fusion peptide is much longer and may represent a problem for some recombinant proteins.
