The Role of Preannouncing In Innovation Launch Strategy

The objective of this master’s thesis was to examine the role of preannouncing in innovation launch strategy. Preannouncing was studied from three different angles that were preannouncement usage, preannouncement timing and preannouncement goals and from two different perspectives that were the firm’s internal strategy and the external circumstances. The firm’s internal strategy encompassed the product strategy the firm had chosen. The external circumstances consisted of the industry, the nature of competition and the nature of market. Additionally, the product’s performance in the short term was studied in order to be able to speak out whether it is advantageous to preannounce. The empirical study was conducted as a partial replication study. The data for the empirical part was collected with a wide mailing and Internet enquiry in October 2008 – June 2009. Sample (N = 713) consisted of Finnish firms representing different industries and innovation activities. The data collection produced 272 answers and thus, the final response rate of the study was 38.15 %. The data was analyzed by using Microsoft Excel and statistical analysis program SAS Enterprise Guide. As a conclusion, the major results indicate that even if the firms use preannouncing quite often (54.8 % of the respondents), preannouncing behavior cannot be explained by industry. However, out of other external circumstances, the customer related turbulence affects on preannouncing usage. It was also revealed that the product type has an effect on preannouncing behavior. Additionally, preannouncement timing was noticed to differ according to audiences (distributors and end users).

AU COMMENCEMENT ÉTAIT LA MÉTAPHORE: UNE INTUITION PRÉCOCE DE NIETZSCHE SUR LA PRIMAUTÉ DE LA MÉTAPHORE COMME MATRICE COGNITIVE

RÉSUMÉ Cette étude met en perspective le précédent constitué par les travaux précoces du jeune Nietzsche où ce dernier fait valoir la force structurante de la métaphore comme matrice des facultés cognitives. Nous offrons d’abord une brève esquisse des postulats et des acquis des grammaires cognitives associées aux travaux d’Eleanor Rosch, ensuite de George Lakoff et Mark Johnson, ainsi qu’à la notion d’inscription corporelle de l’esprit développée par Francesco Varela. Cet exercice sert de propédeutique à une série de lectures tangentes mobilisant divers angles d’approche appelés à faciliter noter évaluation des contributions de Nietzsche au domaine de la cognition. Les travaux examinés nous situent dans la période contemporaine de la publication de son premier grand ouvrage, La naissance de la tragédie (1872) : les notes pour le cours intitulé Présentation de la rhétorique ancienne (Darstellung der antiken Rhetorik), prononcé au semestre d’hiver 1872-1873 à l’Université de Bâle, ensuite ses Theoretische Studien, datant de l’été 1873, avec un renvoi aux développements plus tardifs dans le Gai Savoir (1882). La thèse de Nietzsche peut être résumée comme suit : tous les éléments de l’appareil catégorial et du régime conceptuel à l’aide desquels nous appréhendons la réalité, a fortiori la notion de vérité qui en est le garant, sont le « précipité » ou le résidu d’un faisceau de métaphores qui constituent la force structurante des facultés cognitives. Si chez Kant nous n’avons accès qu’aux phénomènes et non au noumène, chez Nietzsche nous n’avons affaire qu’à des perspectives ou des points de vues alors que la réalité nous est monnayée sous forme de vérités qui sont des fictions ou des métaphores usées. Il ressort de cet examen que le tropisme endogène de la langue constitue une force majeure dans l’implémentation d’une conceptualité qui a la vertu d’oblitérer sa préhistoire et de se ménager un statut qui est incessamment implosé par le reflux de l’imagination créatrice nourrie par la force métaphorique qui répond à une impulsion foncière que Nietzsche associe à une « force artiste » (Kunstkraft) qui tend à démultiplier les perspectives dont la généalogie se conjugue à l’exponentiel.

Det gyldne snitt : den estetiske dimensjon, en kilde til helse oget etisk anliggende

Within caring science, investigations and explorations have been carried out on the ontology of caring, and many aspects of the field have been the subject of scientific research. The main subject for this study is grounded on the human need for aesthetics. The purpose is to find how the aesthetic dimension is taken into consideration and how the aesthetic surroundings are evaluated and attended to, in the general hospitals in Norway. The theoretical perspective is founded basicly on the study of litterature from caring science and philosophy. The aim is to develop a disposition for a framework on the aesthetic surroundings in the hospitals, and to develop phenomenological and ontological knowledge and understanding of the aesthetic dimension. The study aspires to attain a deeper understanding of the aesthetic acknowledgment and of the aesthetic needs. The focus is how the aesthetic dimension can promote health and wellbeing, both for patients and for the caring staff, in the general hospitals and why the aesthetic dimension should be obligatory in `evident care¿. The study concentrates on 11 selected categories in the hospital environment, where aesthetics is of importance. The research is implemented on 5 part studies: 1. part is a study of caring science and philosophical theories about aesthetics, as a framework for the investigation. 2. part is a survey of the physical environment, in Norwegian somatic hospitals, with focus on aesthetics. This by analyzing the strategy plans for the hospitals. 3. and 4. part is questionnaires to patients and nurses to get their opinion and evaluation of the aesthetic environment in the hospitals they are connected to, and their opinion on how this influences the health and wellness for both patients and caring staff. 5. part is qualitative interviews with 16 experts, to get their opinion and evaluation of the aesthetic environment in hospitals they are or have been connected to. How would the experts like the aesthetic surroundings to be, and also their opinion on what influence they think aesthetics has on health and wellness. The main literature of caring science is rooted in K. Erikssons caring theory as well as philosophic literature; mainly I. Kant, Platon and Y. Hirn's theories on aesthetics. Various scientificresearchers of aesthetics have also been referred to. The methodological approach is a triangulation with a hermeneutic exploration, where H.G. Gadamer and Ricoeur provides the inspirational foundation. The findings and conclusions result in the development of new hypothesis for the caring science foundation and suggestions, a disposition for a framework related to future planning of the aesthetic environments in general hospitals. It might be said that a common thread arises/appears in the invariance's (invariables) that are discerned from the analysis and interpretation of the interviews and also important angles shows in the variances that crystallized. Based on the conclusions the study confirms that there is a clearconnection between health, wellness and aesthetics in the environment and that it is an ethical obligationfor those in the caring professions to be aware of and attend to the aesthetic dimension.

Towards increased productivity and quality in software development using agile, lean and collaborative approaches

Dagens programvaruindustri står inför alltmer komplicerade utmaningar i en värld där programvara är nästan allstädes närvarande i våra dagliga liv. Konsumenten vill ha produkter som är pålitliga, innovativa och rika i funktionalitet, men samtidigt också förmånliga. Utmaningen för oss inom IT-industrin är att skapa mer komplexa, innovativa lösningar till en lägre kostnad. Detta är en av orsakerna till att processförbättring som forskningsområde inte har minskat i betydelse. IT-proffs ställer sig frågan: “Hur håller vi våra löften till våra kunder, samtidigt som vi minimerar vår risk och ökar vår kvalitet och produktivitet?” Inom processförbättringsområdet finns det olika tillvägagångssätt. Traditionella processförbättringsmetoder för programvara som CMMI och SPICE fokuserar på kvalitets- och riskaspekten hos förbättringsprocessen. Mer lättviktiga metoder som t.ex. lättrörliga metoder (agile methods) och Lean-metoder fokuserar på att hålla löften och förbättra produktiviteten genom att minimera slöseri inom utvecklingsprocessen. Forskningen som presenteras i denna avhandling utfördes med ett specifikt mål framför ögonen: att förbättra kostnadseffektiviteten i arbetsmetoderna utan att kompromissa med kvaliteten. Den utmaningen attackerades från tre olika vinklar. För det första förbättras arbetsmetoderna genom att man introducerar lättrörliga metoder. För det andra bibehålls kvaliteten genom att man använder mätmetoder på produktnivå. För det tredje förbättras kunskapsspridningen inom stora företag genom metoder som sätter samarbete i centrum. Rörelsen bakom lättrörliga arbetsmetoder växte fram under 90-talet som en reaktion på de orealistiska krav som den tidigare förhärskande vattenfallsmetoden ställde på IT-branschen. Programutveckling är en kreativ process och skiljer sig från annan industri i det att den största delen av det dagliga arbetet går ut på att skapa något nytt som inte har funnits tidigare. Varje programutvecklare måste vara expert på sitt område och använder en stor del av sin arbetsdag till att skapa lösningar på problem som hon aldrig tidigare har löst. Trots att detta har varit ett välkänt faktum redan i många decennier, styrs ändå många programvaruprojekt som om de vore produktionslinjer i fabriker. Ett av målen för rörelsen bakom lättrörliga metoder är att lyfta fram just denna diskrepans mellan programutvecklingens innersta natur och sättet på vilket programvaruprojekt styrs. Lättrörliga arbetsmetoder har visat sig fungera väl i de sammanhang de skapades för, dvs. små, samlokaliserade team som jobbar i nära samarbete med en engagerad kund. I andra sammanhang, och speciellt i stora, geografiskt utspridda företag, är det mera utmanande att införa lättrörliga metoder. Vi har nalkats utmaningen genom att införa lättrörliga metoder med hjälp av pilotprojekt. Detta har två klara fördelar. För det första kan man inkrementellt samla kunskap om metoderna och deras samverkan med sammanhanget i fråga. På så sätt kan man lättare utveckla och anpassa metoderna till de specifika krav som sammanhanget ställer. För det andra kan man lättare överbrygga motstånd mot förändring genom att introducera kulturella förändringar varsamt och genom att målgruppen får direkt förstahandskontakt med de nya metoderna. Relevanta mätmetoder för produkter kan hjälpa programvaruutvecklingsteam att förbättra sina arbetsmetoder. När det gäller team som jobbar med lättrörliga och Lean-metoder kan en bra uppsättning mätmetoder vara avgörande för beslutsfattandet när man prioriterar listan över uppgifter som ska göras. Vårt fokus har legat på att stöda lättrörliga och Lean-team med interna produktmätmetoder för beslutsstöd gällande så kallad omfaktorering, dvs. kontinuerlig kvalitetsförbättring av programmets kod och design. Det kan vara svårt att ta ett beslut att omfaktorera, speciellt för lättrörliga och Lean-team, eftersom de förväntas kunna rättfärdiga sina prioriteter i termer av affärsvärde. Vi föreslår ett sätt att mäta designkvaliteten hos system som har utvecklats med hjälp av det så kallade modelldrivna paradigmet. Vi konstruerar även ett sätt att integrera denna mätmetod i lättrörliga och Lean-arbetsmetoder. En viktig del av alla processförbättringsinitiativ är att sprida kunskap om den nya programvaruprocessen. Detta gäller oavsett hurdan process man försöker introducera – vare sig processen är plandriven eller lättrörlig. Vi föreslår att metoder som baserar sig på samarbete när processen skapas och vidareutvecklas är ett bra sätt att stöda kunskapsspridning på. Vi ger en översikt över författarverktyg för processer på marknaden med det förslaget i åtanke.

Physical characteristics of oily spraying liquids and droplets formed on coffee leaves and glass surfaces

The physical characteristics of a spray liquid are important in getting a good droplet formation and control efficiency over a particular target. As a function of these characteristics, it is possible to decipher which is the best adjuvant based on the respective concentration used during the spray. Therefore, ten spraying liquids were prepared, which varied in concentrations of pesticide lufenuron + profenofos, mineral oil, water and manganese sulfate. Pendant droplets formed from these mixtures were measured to examine their impact on surface tension. Droplets were applied to the surface of coffee leaves and the surface tension, contact angle formed and the leaf area wetted by the droplet, were measured. A smooth glass surface was taken as a comparative to the coffee leaves. The highest concentrations of oil resulted in lower surface tension, smaller contact angles of droplets on leaf surfaces and larger areas wetted by the droplets. Both surfaces showed hydrophilic behavior.

Stock Repurchase Authorizations - Finnish Companies

The aim of this study is to examine the abnormal market reaction caused by share repurchase authorizations. We study this abnormal reaction from five different angles. First four concentrate on average abnormal returns while the fifth concentrates on cumulative abnormal return. Data consists of 508 share repurchase authorization from Finnish stock market. Event study methodology is used to examine the stock price reaction and regression analysis is used to find correlation between actual buybacks and abnormal returns. The empirical results show that markets do usually react positively to share repurchase authorizations. There are some differences depending which of the five angles the abnormal returns are being examined. Statistically we can confirm that some authorization give positive reaction while others do not. Also we didn’t find a statistically significant positive correlation between actual buybacks and abnormal returns.

Pienen kokoluokan CHP-tuotannon kannattavuus kunnallisen lämpölaitoksen yhteydessä

Fossiiliset polttoainevarannot ovat ehtymässä. Nykyisen talouskasvumme perustuessa fossiilisten polttoaineiden kestämättömään käyttöön, on energiantuotantorakenteen muututtava. Euroopan Unioni on asettanut tavoitteet uusiutuvan energian osuuden lisäämiseksi. Näistä syistä johtuen kiinnostus uusiutuvaa energiaa ja hajautettua energiantuotantoa kohtaan on kasvanut viime aikoina. Tämän globaalin ilmiön rinnalla yhteiskuntarakenteen muutos Suomessa on johtanut tilanteeseen, jossa taloudellinen aktiviteetti kasvukeskusten ulkopuolella on hiipumassa. Loogisena ratkaisumallina on syntynyt hankkeita kuten Keski-Karjalan Kehitysyhtiö Oy:n Puhos 2013 - ympäristöalasta uutta liiketoimintaa - hanke. Tämä työ on Puhos 2013 - hankkeeseen tilattu tutkimus, jonka tavoitteena on puuta ja biokaasua polttoaineenaan käyttävän mikroturbiinitekniikkaan pohjautuvan pienen kokoluokan CHP tuotannon kannattavuuden selvittäminen kunnallisen lämpölaitoksen yhteydessä. Tutkimuksessa selvitettiin aluksi pienen kokoluokan CHP tuotannon kannattavuuteen vaikuttavat tekijät, jonka jälkeen opittua tietoa sovellettiin Kiteen Lämmön Arppentien lämpölaitoksen tapaukseen. Kiteen Lämmön taloudellisen kannattavuuden ohella tutkimuksessa huomioitiin uusien liiketoiminta mahdollisuuksien syntyminen alueelle. Käytetyt tutkimusmenetelmät olivat kvalitatiivinen analyysi ja perinteinen investoinnin kannattavuuslaskenta. Tutkimuksen tuloksena muodostettiin strategia, joka maksimoi molemmat edellä mainitut kannattavuuden näkökulmat. Kehitetyn strategian Kiteen Lämmön tulosta maksimoiva osuus muodostuu oman käyttösähkön tuottamisen aloittamisesta Arppentien lämpölaitoksella 30 kWe mikroturbiinilla käyttäen polttoaineena Bio10 Oy:n toimittamaa biokaasua. Uusien liiketoiminta mahdollisuuksien synty alueelle mahdollistetaan puolestaan kehittämällä puun kaasutukseen perustuva modulaarinen CHP laitos yhteistyössä Mekrijärven tutkimusaseman ja suomalaisten laitevalmistajien kanssa.

Modified method for bronchial suture by Ramirez Gama compared to separate stitches suture: experimental study

OBJECTIVE: To experimentally compare two classic techniques described for manual suture of the bronchial stump.METHODS: We used organs of pigs, with isolated trachea and lungs, preserved by refrigeration. We dissected 30 bronchi, which were divided into three groups of ten bronchi each, of 3mm, 5mm, and 7mm, respectively. In each, we performed the suture with simple, separated, extramucosal stitches in five other bronchi, and the technique proposed by Ramirez and modified by Santos et al in the other five. Once the sutures were finished, the anastomoses were tested using compressed air ventilation, applying an endotracheal pressure of 20mmHg.RESULTS: the Ramirez Gama suture was more effective in the bronchi of 3, 5 and 7 mm, and there was no air leak even after subjecting them to a tracheal pressure of 20mmHg. The simple interrupted sutures were less effective, with extravasation in six of the 15 tested bronchi, especially in the angles of the sutures. These figures were not significant (p = 0.08).CONCLUSION: manual sutures of the bronchial stumps were more effective when the modified Ramirez Gama suture was used in the caliber bronchi arms when tested with increased endotracheal pressure.

Yksityisen pysäköinninvalvonnan laintulkinnalliset ongelmat

Tutkielman tavoitteena on paneutua yksityisen pysäköinninvalvonnan lain-tulkinnallisiin ongelmiin Suomessa. Lähtökohtana kysymyksenasettelulle on kansallinen lainsäädäntö, oikeustapaukset, sopimusoikeudelliset peri-aatteet ja oikeuskirjallisuus. Julkinen pysäköinninvalvonta on Suomessa poliisin ja kuntien vastuulla. Suomessa ei ole voimassa yksityistä pysäköinninvalvontaa koskevaa omaa lakia. Yksityisen pysäköinninvalvonnan on nykyisellään katsottu si-sältävän merkittävää julkisen vallan käyttöä, jolloin se tekee siitä perustus-lain vastaista. Samalla yksityinen pysäköinninvalvonta voidaan kuitenkin nähdä sopimukseen perustuvana, laillisena, liiketoimena. Näkökulmien pohdinta tuo esiin laintulkinnallisia ongelmia sekä ongelmia, jotka liittyvät sopimuksen syntymisen kriteereihin.

Logistics of North-West Russia and Rail Baltica: Standpoints of Private Sector

The main aims of the present report are to describe the current state of railway transport in Russia, and to gather standpoints of Russian private transportation logistics sector towards the development of new railway connection called Rail Baltica Growth Corridor, connecting North-West Russia with Germany through the Baltic States and Poland. North-West Russia plays important role not only in Russian logistics, but also wider European markets as in container sea ports handling is approx. 2.5 mill. TEU p.a. and handling volume in all terminals is above 190 million tons p.a. The whole transportation logistics sector is shortly described as an operational environment for railways – this is done through technical and economic angles. Transportation development is always going in line with economics of the country, so the analysis on economical development is also presented. Logistics integration of the country is strongly influenced by its engagement in the international trade. Although, raw material handling at sea ports and container transports (imports) are blossoming, domestic transportation market is barely growing (in long-term perspective). Thus, recent entrance of Russia into World Trade Organization (WTO) is analyzed theme in this research, as the WTO is an important regulator of the foreign trade and enabler of volume growth in foreign trade related transportation logistics. However, WTO membership can influence negatively the development of Russia’s own industry and its volumes (these have been uncompetitive in global markets for decades). Data gathering in empirical part was accomplished by semi-structured case study interviews among North-West Russian logistics sector actors (private). These were conducted during years 2012-2013, and research compiles findings out of ten case company interviews. Although, there was no sea port involved in the study, most of the interviewed companies relied in European Logistics within significant parts in short sea shipping and truck combined transportation chains (in Russian part also using railways). As the results of the study, it could be concluded that Rail Baltica is seen as possible transport corridor in most of the interviewed companies, if there is enough cargo available. However, interviewees are a bit sceptical, because major and large-scale infrastructural improvements are needed. Delivery time, frequency and price level are three main factors influencing the attractiveness of Rail Baltica route. Price level is the most important feature, but if RB can offer other advantages such as higher frequency, shorter lead times or more developed set of value-added services, then some flexibility is possible for the price level. Environmental issues are not the main criteria of today, but are recognized and discussed among customers. Great uncertainty exists among respondents e.g. on forthcoming sulphur oxide ban on Baltic Sea shipping (whether or not it is going to be implemented in Russia). Rather surprisingly, transportation routes to Eastern Europe and Mediterranean area are having higher value and price space than those to Germany/Central Europe. Border crossing operations (traction monopoly at rails and customs), gauge widths as well as unclear decision-making processes (in Russia), are named as hindering factors. Performance standards for European connected logistics among Russian logistics sector representatives are less demanding as compared to neighbourhood countries belonging to EU.

On the numerical integration of rigid body nonlinear dynamics in presence of parameters singularities

One of the main complexities in the simulation of the nonlinear dynamics of rigid bodies consists in describing properly the finite rotations that they may undergo. It is well known that, to avoid singularities in the representation of the SO(3) rotation group, at least four parameters must be used. However, it is computationally expensive to use a four-parameters representation since, as only three of the parameters are independent, one needs to introduce constraint equations in the model, leading to differential-algebraic equations instead of ordinary differential ones. Three-parameter representations are numerically more efficient. Therefore, the objective of this paper is to evaluate numerically the influence of the parametrization and its singularities on the simulation of the dynamics of a rigid body. This is done through the analysis of a heavy top with a fixed point, using two three-parameter systems, Euler's angles and rotation vector. Theoretical results were used to guide the numerical simulation and to assure that all possible cases were analyzed. The two parametrizations were compared using several integrators. The results show that Euler's angles lead to faster integration compared to the rotation vector. An Euler's angles singular case, where representation approaches a theoretical singular point, was analyzed in detail. It is shown that on the contrary of what may be expected, 1) the numerical integration is very efficient, even more than for any other case, and 2) in spite of the uncertainty on the Euler's angles themselves, the body motion is well represented.

Three-dimensional supersonic flow over a spike-nosed body of revolution

The unsteady, viscous, supersonic flow over a spike-nosed body of revolution is numerically investigated by solving the Navier-Stokes equations. The time-accurate computations are performed employing an implicit algorithm based on the second-order time-accurate LU-SGS scheme with the incorporation of a subiteration procedure to maintain time accuracy. The characteristics of the flow field for a Mach number of 3.0, Reynolds number of 7.87 x 10(6)/m, and angles of attack of 5 and 10 degrees are described. Self-sustained asymmetric shock wave oscillations were observed in the numerical computations for these angles of attack. The main characteristic of the flow field, as well as its influence on drag coefficient is discussed.

Neutron tomography using projection data obtained by Monte Carlo simulation for nondestructive evaluation

This work present the application of a computer package for generating of projection data for neutron computerized tomography, and in second part, discusses an application of neutron tomography, using the projection data obtained by Monte Carlo technique, for the detection and localization of light materials such as those containing hydrogen, concealed by heavy materials such as iron and lead. For tomographic reconstructions of the samples simulated use was made of only six equal projection angles distributed between 0º and 180º, with reconstruction making use of an algorithm (ARIEM), based on the principle of maximum entropy. With the neutron tomography it was possible to detect and locate polyethylene and water hidden by lead and iron (with 1cm-thick). Thus, it is demonstrated that thermal neutrons tomography is a viable test method which can provide important interior information about test components, so, extremely useful in routine industrial applications.
