The objective of this research is to observe the state of customer value management in Outotec Oyj, determine the key development areas and develop a phase model with which to guide the development of a customer value based sales tool. The study was conducted with a constructive research approach with the focus of identifying a problem and developing a solution for the problem. As a basis for the study, the current literature involving customer value assessment and solution and customer value selling was studied. The data was collected by conducting 16 interviews in two rounds within the company and it was analyzed by coding openly. First, seven important development areas were identified, out of which the most critical were Customer value mindset inside the company and Coordination of customer value management activities. Utilizing these seven areas three functionality requirements, Preparation, Outotecs value creation and communication and Documentation and three development requirements for a customer value sales tool were identified. The study concluded with the formulation of a phase model for building a customer value based sales tool. The model included five steps that were defined as 1) Enable customer value utilization, 2) Connect with the customer, 3) Create customer value, 4) Define tool to facilitate value selling and 5) Develop sales tool. Further practical activities were also recommended as a guide for executing the phase model.

To determine if radiocontrast impairs vascular relaxation of the renal artery, segments (4-5 mm in length) of canine renal artery were suspended in vitro in organ chambers to measure isometric force (95% O2/5% CO2, at 37C). Arterial segments with and without endothelium were placed at the optimal point of their length-tension relation and incubated with 10 M indomethacin to prevent synthesis of endogenous prostanoids. The presence of nonionic radiocontrast (iohexol, Omnipaque 350, 1 ml in 25 ml control solution, 4% (v/v)) did not alter endothelium-dependent relaxation to acetylcholine in rings precontracted with both norepinephrine and prostaglandin F2alpha (N = 6). When the rings were precontracted with prostaglandin F2alpha, the presence of ionic contrast did not inhibit the relaxation of the arteries. However, in canine renal arteries contracted with norepinephrine, the presence of ionic radiocontrast (diatrizoate meglumine and diatrizoate sodium, MD-76, 1 ml in 25 ml control solution, 4% (v/v)) inhibited relaxation in response to acetylcholine, sodium nitroprusside (N = 6 in each group), and isoproterenol (N = 5; P < 0.05). Rings were relaxed less than 50% of norepinephrine contraction. Following removal of the contrast, vascular relaxation in response to the agonists returned to normal. These results indicate that ionic radiocontrast nonspecifically inhibits vasodilation (both cAMP-mediated and cGMP-mediated) of canine renal arteries contracted with norepinephrine. This reversible impairment of vasodilation could inhibit normal renal perfusion and act as a mechanism of renal failure following radiocontrast infusion. In the adopted experimental protocol the isoproterenol-induced relaxation of renal arteries precontracted with norepinephrine was more affected, suggesting a pivotal role of the cAMP system.

Chagas' myocardiopathy, caused by the intracellular protozoan Trypanosoma cruzi, is characterized by microvascular alterations, heart failure and arrhythmias. Ischemia and arrythmogenesis have been attributed to proteins shed by the parasite, although this has not been fully demonstrated. The aim of the present investigation was to study the effect of substances shed by T. cruzi on ischemia/reperfusion-induced arrhythmias. We performed a triple ischemia-reperfusion (I/R) protocol whereby the isolated beating rat hearts were perfused with either Vero-control or Vero T. cruzi-infected conditioned medium during the different stages of ischemia and subsequently reperfused with Tyrode's solution. ECG and heart rate were recorded during the entire experiment. We observed that triple I/R-induced bradycardia was associated with the generation of auricular-ventricular blockade during ischemia and non-sustained nodal and ventricular tachycardia during reperfusion. Interestingly, perfusion with Vero-infected medium produced a delay in the reperfusion-induced recovery of heart rate, increased the frequency of tachycardic events and induced ventricular fibrillation. These results suggest that the presence of parasite-shed substances in conditioned media enhances the arrhythmogenic effects that occur during the I/R protocol.

Smart home implementation in residential buildings promises to optimize energy usage and save significant amount of energy simply due to a better understanding of user's energy usage profile. Apart from the energy optimisation prospects of this technology, it also aims to guarantee occupants significant amount of comfort and remote control over home appliances both at home locations and at remote places. However, smart home investment just like any other kind of investment requires an adequate measurement and justification of the economic gains it could proffer before its realization. These economic gains could differ for different occupants due to their inherent behaviours and tendencies. Thus it is pertinent to investigate the various behaviours and tendencies of occupants in different domain of interests and to measure the value of the energy savings accrued by smart home implementations in these domains of interest in order to justify such economic gains. This thesis investigates two domains of interests (the rented apartment and owned apartment) for primarily two behavioural tendencies (Finland and Germany) obtained from observation and corroborated by conducted interviews to measure the payback time and Return on Investment (ROI) of their smart home implementations. Also, similar measures are obtained for identified Australian use case. The research finding reveals that building automation for the Finnish behavioural tendencies seems to proffers a better ROI and payback time for smart home implementations.

IoT consists of essentially thousands of tiny sensor nodes interconnected to the internet, each one of which executes the programmed functions under memory and power limita- tions. The sensor nodes are distributed mainly for gathering data in various situations. IoT envisions the future technologies such as e-health, smart city, auto-mobiles automa- tion, construction sites automation, and smart home. Secure communication of data under memory and energy constraints is major challenge in IoT. Authentication is the first and important phase of secure communication. This study presents a protocol to authenticate resource constraint devices in physical proximity by solely using the shared wireless communication interfaces. This model of authentication only relies on the abundance of ambient radio signals to authenticate in less than a second. To evaluate the designed protocol, SkyMotes are emulated in a network environment simulated by Contiki/COOJA. Results presented during this study proves that this approach is immune against passive and active attacks. An adversary located as near as two meters can be identified in less than a second with minimal expense of energy. Since, only radio device is used as required hardware for the authentication, this technique is scalable and interoperable to heterogeneous nature of IoT.

Tyn alustavana tavoitteena oli havaita yrityksen ict-ryhmss kytettvien teknisten vlineiden, informaation hallinnan jrjestelmien ja ryhmn tytilojen vaikutus hiljasen tiedon jakamiseen tai sen estymiseen. Tyss tarkasteltiin mys vaikutusta ryhmn oppimiseen sek ryhmn muodostuvan hiljaisen tiedon syntymisen ja henkilitymisen syihin sek hiljaisen tiedon laatuun. Lisksi tyss pyritn lytmn tapoja, joiden avulla hiljaista tietoa voidaan hydynt ja jakaa ryhmss siten ett se mahdollistaa mys ryhmn oppimisen. Haastatteluissa nousivat esiin informaation hallintaongelmat, jotka johtuvat informaation hajautumisesta informaation eri hallinta jrjestelmiin, tietoturvamrysten aiheuttamiin esteisiin ja kriittisen teknisen dokumentaation tallentamiseen. Nm vaikeuttavat tallennetun informaation hydyntmist ict-ryhmss. Tm osaltaan aiheuttaa hiljaisen tiedon henkilitymist ryhmss ja hiljaisen tiedon jakamisen menetelmien j hydyntmtt. Haastatteluissa osoittautui, ett hiljaisen tiedon hydyntmisongelmat johtuvat osittain ryhmn sisisten yhteyksien verkoston rakenteesta. Vahvojen linkkien vhyys ryhmss ja vahvojen linkkien suuntautuminen ryhmn ulkoisiin verkostoihin vaikeuttaa hiljaisen tiedon siirtymist ryhmss ja aiheuttaa hiljaisen tiedon henkilitymist. Kiire todettiin ryhmn kannalta ongelmalliseksi hiljaisen tiedon jakamisen ja hydyntmisen esteeksi. Tiedon adaptaatioon ja omaksumiseen liittyvt ongelmat ovat sidoksissa aikaan ja hiljaisen tiedon henkilitymiseen ryhmss. Ryhmty ja ryhmn pivittisess toiminnassa kytettviss olevat hiljaisen tiedon jakamisen menetelmt osoittautuvat sopivimmiksi edistmn ryhmn yhteistykyky sek sosiaalisen rakenteen ja luottamuksen kehittymist. Ne poistavat mys tiedon omaksumisen ja adaptaation esteit. Ryhmty vaikuttaa mynteisesti ryhmn kollektiiviseen osaamiseen ja ryhmn hiljaisen tiedon kehittymiseen. Lisksi se parantaa teknisen dokumentaation ymmrrettvyytt.

Tmn Pro -gradu tutkielman tavoitteena on tutkia suomalaisen yrityshautomo-konseptin soveltuvuutta venlisten ICT-alan start-up-yrittjien tarpeisiin. Tutkielma on tehty suomalaiselle prssiyhtille, joka laajentaa toimintaansa Venjlle perustamalla teknologiakeskuksen Pietariin. Kohdeyritys on teettnyt useita selvi-tyksi Pietarin ICT-sektorista, sen ongelmista ja kehitystarpeista. Sen sijaan ksityst ei ole siit, miten haastavaksi yksittinen yrittj kokee liiketoiminta-ympristn ja mit tukipalveluita hn liiketoiminnassaan tarvitsee. Tutkimuksen tavoitteena on vastata nihin kysymyksiin sek peilata saatuja vastauksia kohdeyrityksen Suomessa tarjoamiin hautomopalveluihin. Kirjallisuuskatsauksessa on kyty lpi yrityshautomotoiminnan historiaa ja toiminnan saamia erilaisia muotoja. Lisksi on perehdytty tutkimuksiin hautomotoimin-nan vaikuttavuudesta ja kriittisist menestystekijist. Tutkimus on lhestymistavaltaan laadullinen case-tutkimus. Kytnnss ty to-teutettiin kyselytutkimuksena haastattelemalla kymment pietarilaista, pienen ICT-alan yrityksen johtajaa. Haastatteluiden perusteella kohdeyrityksen hautomokonseptia ei ole mahdollista siirt suoraviivaisesti venliseen toimintaympristn. Kulttuurierot maiden vlill ovat merkittvt, eik niit ole lyhyell tai keskipitkll aikavlill mahdollista poistaa. Etenkin yleinen luottamuksen puute vaikeuttaa konseptin implementointia. Alkavien ICT-yritysten haasteet ovat pitklti samoja rajan kummallakin puolen. Rahoituksen puute ja ongelmat myynti- ja markkinointiosaamisessa tulivat haas-tatteluissa vahvasti esille. Liiketoimintaosaamisessa on paljon parannettavaa. Ensimmisi toteutettavaksi suositeltuja palveluita ovat siten yrittjvalmennus ja myynnin ja markkinoinnin typaja. Lopuksi voi todeta, ett useille kohdeyrityksen tarjoamille yksittisille palveluille on selke tarve. Siihen, mit kytnnss on mahdollista ja/tai kannattavaa toteuttaa, ei oteta tss tutkimuksessa kantaa.

Enterprise resource planning (ERP) software is used to combine all the functions happening inside the organization with the help of one software. All the data is centralized which makes it easy to manage information for all participants. The literature on ERP is studied thoroughly the whole process of adoption till the implementation and final evaluations. But studies that focus on small and medium sized enterprises are limited in number when compared to the large scale enterprises. In case of Pakistan, research is very limited. In this thesis, the author tries to analyze the current status of SMEs usage of ERP system. The benefits obtained and challenges faced by SMEs of Pakistan are studied. Framework presented by Shang and Seddon (2000) is used to understand the benefits obtained by the SMEs in Pakistan. This is a comprehensive framework that classifies the benefits obtained by the ERP adoption, into five categories: operational benefits, managerial benefits, Strategic benefits, IT benefits, and Organizational benefits. The results show that SMEs of Pakistan are also getting many benefits after adoption of ERP. Most of the firms had implemented SAP software. Operational benefits were mentioned by all the firms. The most important benefits were report generation, quick access to critical information, better product and cost planning. Respondents also mentioned that they had reduced corruption as a result of ERP implementation. It is also an important benefit considering high corruption rate in Pakistan. Along with benefits, challenges faced by Pakistani SMEs included infrastructure problems like electricity, difficulties with integration of one module with other module, costs of adoption and lack of skilled ERP consultants. Further studies in this regard can be conducted on cloud based ERP which is fast growing all around the world.

Developing nations vary in data usage techniques with respect to developed nations because of lack of standard information technology architecture. With the concept of globalization in the modern times, there is a necessity of information sharing between different developing nations for better advancements in socio-economic and science and technology fields. A robust IT architecture is needed and has to be built between different developing nations which eases information sharing and other data usage methods. A framework like TOGAF may work in this case as a normal IT framework may not fit to meet the requirements of an enterprise architecture. The intention of the thesis is to build an enterprise architecture between different developing nations using a framework TOGAF

Today, companies need to mind the environment in all their actions. Policies, regulations and growing pressure from environmentally conscious public are driving corporations to invest increasingly in their green images. Communication plays a key role in forming and maintaining that image. This thesis explores how six selected companies communicate about their environmental efforts and activities, and its linkage to their green images, in annual and sustainability reports and in Facebook. The companies come from the U.S. and Europe and operate in three different industries: ICT, oil and gas, and aerospace & defense. Qualitative and quantitative content analyses are conducted to examine 36 reports and 121 Facebook messages, collected from the period of 2010-2014, and from 2005 for comparison. The results show that although the quality and quantity of environmental disclosure is increasing, there is still room for improvement. Overall, disclosure in the ICT sector is on the highest level. The European companies disclose more and on average have stronger green images than the American ones. Emissions and ways to reduce them is by far the most covered topic in both continents and in all three industry sectors. The messages in Facebook are closer to advertising, and overall the platform is utilized surprisingly little.

The human neuromuscular system is susceptible to changes within the thermal environment. Cold extrinsic temperatures can significantly reduce muscle and nervous system function and communication, which can have consequences for motor performance. A repeated measures design protocol exposed participants to a 12C cold water immersion (CWI) up to the ankle, knee, and hip to determine the effect that reduced skin and muscle temperature had on balance and strength task execution. Although a linear reduction in the ability to perform balance tasks was seen from the control condition through to the hip CWI, results from the study indicated a significant reduction in dynamic balance (Star Excursion Balance Test reach distance) performance from only the hip CWI (P<0.05). This reduced performance could have been due to an increase in joint stiffness, increased agonist-antagonist co-contraction, and/or reduced isokinetic muscular strength. Reduced physical performance due to cold temperature could negatively impact outdoor recreational athletics.

Cette recherche part du constat de lutilisation des nouvelles technologies qui se gnralise dans lenseignement universitaire (tant sur campus quen enseignement distance), et traite cette question sous trois aspects institutionnel, pdagogique et technologique. La recherche a t mene travers quinze universits canadiennes o nous avons interrog vingt-quatre universitaires, nommment des responsables de centres de pdagogie universitaire et des experts sur la question de lintgration des technologies lenseignement universitaire. Pour le volet institutionnel, nous avons eu recours un cadre thorique qui met en relief le changement de structure et de fonctionnement des universits lre dInternet, suivant le modle thorique de lOpen System Communications Net de Kershaw et Safford (1998, 2001). Les rsultats, laune de ce modle, confirment que les universits conventionnelles sont dans une phase de transformation due lutilisation des technologies de l'information et de la communication (TIC). De plus, les cours hybrides, la bimodalit, des universits entirement distance visant une clientle estudiantine au-del des frontires rgionales et nationales, des universits associant plusieurs modles, des universits fonctionnant base dintelligence artificielle, sont les modles principaux qui ont la forte possibilit de simposer dans le paysage universitaire nord-amricain au cours des prochaines dcennies. Enfin, la lumire du modle thorique, nous avons explor le rle de luniversit, ainsi en transformation, au sein de la socit tout comme les rapports ventuels entre les institutions universitaires. Sagissant de laspect pdagogique, nous avons utilis une perspective thorique fonde sur le modle du Community of Inquiry (CoI) de Garrison, Anderson et Archer (2000), revu par Vaughan et Garrison (2005) et Garrison et Arbaugh (2007) qui prne notamment une nouvelle culture de travail luniversit fonde sur trois niveaux de prsence. Les rsultats indiquent limportance dlments relatifs la prsence denseignement, la prsence cognitive et la prsence sociale, comme le suggre le modle. Cependant, la rcurrence -dans les trois niveaux de prsence- de certains indicateurs, suggrs par les rpondants, tels que lchange dinformation, la discussion et la collaboration, nous ont amens conclure la non-tanchit du modle du CoI. De plus, certaines catgories, de par leur frquence dapparition dans les propos des interviews, mriteraient davoir une considration plus grande dans les exigences pdagogiques que requiert le nouveau contexte prvalant dans les universits conventionnelles. Cest le cas par exemple de la catgorie cohsion de groupe . Enfin, dans le troisime volet de la recherche relatif la dimension technologique, nous nous sommes inspirs du modle thorique dOlapiriyakul et Scher (2006) qui postule que linfrastructure dans lenseignement doit tre la fois une technologie pdagogique et une technologie dapprentissage pour les tudiants (instructional technology and student learning technology). Partant de cette approche, le volet technologique de notre recherche a consist identifier les fonctionnalits exiges de la technologie pour induire une volution institutionnelle et pdagogique. Les rsultats cet gard ont indiqu que les raisons pour lesquelles les universits choisissent dintgrer les TIC lenseignement ne sont pas toujours dordre pdagogique, ce qui explique que la technologie elle-mme ne revte pas forcment les qualits a priori requises pour une volution pdagogique et institutionnelle. De ce constat, les technologies appropries pour une relle volution pdagogique et institutionnelle des universits ont t identifies.

Cette thse est une enqute pistmologique qui sinterroge sur la persistance de lther dans le champ de la technologie. De faon gnrale, le mot ther voque un modle conceptuel de la physique pr-einsteinienne, celui dun milieu invisible permettant la propagation de la lumire et des ondes lectromagntiques. Or, ce nest l quune des figures de lther. Dans plusieurs mythologies et cosmogonies anciennes, le nom ther dsignait le feu originel contenu dans les plus hautes rgions clestes. Aristote nommait ther , par exemple, le cinquime tre , ou cinquime lment . La chimie a aussi sa propre figure de lther o il donne son nom un compos chimique, le C4H10O, qui a t utilis comme premier anesthsiant gnral la fin du XIXe sicle. Lapparition soutenue dans lhistoire de ces figures disparates de lther, qui a priori ne semblent pas entretenir de relation entre elles, est pour nous la marque de la persistance de lther. Nous dfendons ici largument selon lequel cette persistance ne se rsume pas la constance de lattribution dun mot ou dun nom diffrents phnomnes dans lhistoire, mais lactualisation dune mme signature, throgne. linvitation dAgamben et en nous inspirant des travaux de Nietzsche et Foucault sur lhistoire-gnalogie et ceux de Derrida sur la dconstruction, notre thse amorce une enqute historique motive par un approfondissement dune telle thorisation de la signature. Pour y parvenir, nous proposons de placer lther, ou plutt la signature-ther, au cur de diffrentes enqutes historiques proccupes par le problme de la technologie. En abordant sous cet angle des enjeux disparates la lgitimation des savoirs narratifs, la suspension des sens, la pseudoscience et la magie, les rvolutions de linformation, lobsession pour le sans-fil, lconomie du corps, la virtualisation de la communication, etc. , nous proposons dans cette thse autant damorces pour une histoire autre, une contre-histoire.
