Elevator landing doors are fire tested to measure their fire resistance. The objective of this master’s thesis was to create a method to evaluate the fire tests and the organizations that provide these testing services. The main focus area was in creating accurate evaluation criteria and weighting the criteria. The thesis was formed by first presenting the reader with the literature review of the closest related theories. The theories which were chosen were systematic decision making, supplier selection, and make or buy and outsourcing theories. In the empirical section the created process of evaluating fire testing is presented, with analysis of the current situation of fire testing processes and evaluation methods. Evaluating fire testing services required two types of criteria to be formed, technical criteria to evaluate the technical requirements, and service criteria to evaluate the organization which was offering the testing service. These criteria formed the core for the evaluation process which consisted of five different phases that were developed based on the literature review. The process was tested to create best practices and to make improvement proposals accordingly. Systematical process for evaluating fire testing helps to recognize the most important technical and service related aspects. The created criteria can be also used in future to benchmark and monitor the situation of fire testing. The results of the process can be used when deciding whether to outsource the service or to keep it in-house.

Constitutive laws for strong geometric non-linearity

This paper is divided into two different parts. The first one provides a brief introduction to the fractal geometry with some simple illustrations in fluid mechanics. We thought it would be helpful to introduce the reader into this relatively new approach to mechanics that has not been sufficiently explored by engineers yet. Although in fluid mechanics, mainly in problems of percolation and binary flows, the use of fractals has gained some attention, the same is not true for solid mechanics, from the best of our knowledge. The second part deals with the mechanical behavior of thin wires subjected to very large deformations. It is shown that starting to a plausible conjecture it is possible to find global constitutive equations correlating geometrical end energy variables with the fractal dimension of the solid subjected to large deformations. It is pointed out the need to complement the present proposal with experimental work.

Soraääniä, sitaatteja ja suunnitelmallisuutta. Moniäänisyys Eira Stenbergin romaanituotannossa

Tutkin väitöskirjassani Eira Stenbergin (s. 1943) romaanituotannon moniäänisyyttä, joka liittyy niin subjektiin, kertomisen prosessiin kuin todellisuuskäsityksiin. Aineistonani ovat Stenbergin 1980–1990-luvulla kirjoittamat, tutkimusongelmani kannalta keskeiseen ajanjaksoon kuuluvat romaanit Paratiisin vangit (1984), Häikäisy (1987), Kuun puutarhat (1990) sekä Gulliverin tytär (1993). 1980-luvulla postmodernista tuli kirjallisen kulttuurin keskeisimpiä aiheita Suomessa, ja subjektista tuli ongelma jopa siinä määrin että puhuttiin sen kuolemasta. Ääni oli 1980-luvulla osa subjektia koskevaa keskustelua: yhtäältä nousevan feministisen liikkeen identiteettipoliittisena ja emansipatorisena metaforana, toisaalta jälkistrukturalismin antihumanismin uhkakuvana, joka koski subjektin ääntä alkuperän lähteenä ja persoonan ilmaisuna. Äänen käsitteen voidaan katsoa implikoivan jonkinlaista käsitystä subjektista, ja tarkastelenkin tutkimuksessani erityisesti henkilöhahmoja, kertojia ja kertomisen prosessia, mutta myös tekijän suunnitelmallisuutta ja kuulijaa kohti orientoitumista. Yhdistelen tutkimuksessani retorista kertomuksen teoriaa dekonstruktioon sekä feministisiin subjektiteorioihin. Myös Mihail Bahtinin käsitys moniäänisestä romaanista on työssäni keskeinen. Problematisoin tutkimuksessani äänen kytköksen sisimmän ilmaisuun, omistamiseen ja auktoriteettiin ja ymmärrän sen keskustelualueena, jossa kohtaavat erilaiset arvot ja näkemykset maailmasta. Tällöin kaikenkattava puhe subjektin kuolemasta sekä käsitykset 1980-luvun kirjallisuudesta maailmasta vieraantuneena ja yksityisen alueelle vetäytyvänä problematisoituvat. Stenbergin tuotannon perusteella voi sanoa, että kirjallisuuden äänet saavat merkityksensä vasta erilaisina äänensävyinä konkreettisissa ja ainutkertaisissa konteksteissa. Tämä viittaa tarpeeseen ymmärtää kirjallisuusteoreettisessa keskustelussa usein historiattomana ja universaalina nähty käsite historiaan paikantuneena: eivät vain erityiset aineistot, vaan myös erityiset kontekstit määrittelevät äänen saamia merkityksiä.

Social entrepreneurship – Believe in it or not!

The practice of social entrepreneurship already exists for a long time but the concept is quite new and has more recently raised a growing interest among academics. However, the majority of researches and considerations about the subject have taken a strong positive concern by omitting some sort of a critical reflection. The idea of this study is to consider the gap between the very optimistic and the more precautious concerns about social entrepreneurship. It means presenting the advantages and downsides connected to the topic in the business, public and third sector. The aim is to help the reader building his/her own belief on social entrepreneurship by considering the positive and negative sides of social entrepreneurship. Hence, the research is intended to take a critical step and aims to answer to the following research questions:  Shall we believe in social entrepreneurship?  What are the reasons for believing or not in social entrepreneurship taking into account the advantages and possible risks of it in the business, public, and third sector? The theoretical framework consists of the comparison between the promising and precautious sides about social entrepreneurship for private, public and non-governmental organizations including the actors or participants inside these sectors. The empirical part is conducted using a qualitative method. Personal interviews of experts in the fields of business, public and third sectors were handled. The purpose of this approach is to compare the critics in theory with the experience of persons dealing with social entrepreneurship. The results from the interviews revealed that in general, reasons for believing in social entrepreneurship prevail over critics about the subject. Social entrepreneurship may not yet represent a full performing business. Concerns for weakening the public power and putting aside the interests of communities in need may exist too. Furthermore, naïve and extra liberal ways of thinking or doing can lead to practices going in opposition with initial social objectives. Nevertheless, problems about social entrepreneurship would be mainly due to the young age of the movement. Time and experience would give better foundations and results to social entrepreneurs. Critics about social entrepreneurship could also easily be done to any sorts of business. Overall, the positive considerations of social entrepreneurship with skillful, motivated and responsible actors could represent some useful tools for enterprises, governments and charities. Some tools among many other possibilities to help people in need.

Toimittajan oikeus uutisoida ja toimitustyötä sääntelevät normit

Luettaessa uutisia lehdestä harvoin pohditaan sitä, onko toimituksellisessa työssä noudatettu lakia ja alan eettisiä ohjeita. Lukija luottaa siihen, että sääntöjä noudatetaan, mutta näin ei aina ole. Käytettäessä materiaalia toiselta lehdeltä jätetään alkuperäinen lähde usein mainitsematta. Tämän tutkielman tarkoituksena on selvittää keskeiset tekijänoikeuslain pykälät ja käytännössä kaikkein keskeisimmät Journalistin ohjeet sanomalehden toimittajan työssä ja miten nämä säännöt pääosin ilmenevät. Suoritetun kyselytutkimuksen perusteella tekijänoikeuslain pykälä oikeus uutisoida toisen lehden uutinen ja Journalistin ohjeista sääntö, jonka mukaan sisältöratkaisut on tehtävä journalistisin perustein, ovat keskeisimpiä sääntöjä käytännön työssä. Tutkimuksessa näitä sääntöjä käsitellään oikeusdogmaattisin menetelmin kieliopillisen tulkinnan kautta sekä toimittajan työn näkökulmasta. Tutkimuksen lainsäädännöllisen viitekehyksen muodostavat Suomen perustuslaki, laki sananvapauden käyttämisestä joukkoviestinnässä, kansallinen tekijänoikeuslaki ja Journalistin ohjeet. Tämän vuoksi tutkimuksessa on aiheellista tarkastella myös sananvapautta ja tekijänoikeuslakia toimituksellisessa työssä sekä näiden suhdetta toisiinsa ja myös median rakenteellista ja toiminnallista muutosta.

Att tala om det osägbara : Nicolaus Cusanus cirkulära filosofi i verket De coniecturis med särskild hänsyn till Nelson Pikes tankar om unio mystica

In my dissertation called Speaking of the unsayable: The circular philosophy of Nicholas of Cusa in his work De coniecturis, I presuppose an internal (conceptual) relation between the personal experience of God of Nicholas of Cusa (1401-64) in 1438 and, on the other hand, his philosophy. I hence try to describe the precise character of this relation. Referring to the Norwegian scholars Egil Wyller and Viggo Rossvær, I assume that there is a circularity in Cusanus’ philosophy which appears as self-references (= a sentence refers to itself: A is explained by B and B is explained by A). Wyller finds three phases in the thought of Cusanus (1. De docta ignorantia I-III, 2. De coniecturis I-II, 3. all subsequent works). Rossvær finds it impossible to presuppose certain phases, as the philosophy of Cusanus continuously proceeds and remains open to new ideas. As Cusanus however treats his experience of God far more consciously in his second work De coniecturis than in De docta ignorantia, I find it possible to distinguish between the earlier Cusanus (De docta ignorantia including his earlier works) and the later Cusanus (De coniecturis, about 1444, as well as the following works). Cusanus creates a philosophy of language in outline expressed in De coniecturis, in which he presents two concepts of necessity, i.e. absolute necessity and logical, or reasonable, necessity. These are interrelated in the sense that the mind, or the self, logically affirms the absolute, or unsayable, necessity, which shows itself in the mind and which the mind affirms conjecturally. The endeavour conceptually to understand absolute necessity implies intuitive (or intellectual) contemplation, or vision (investigatio symbolica), in which the four mental unities (the absolute, the intellectual, the rational and the sensuous) work together according to the rules described in De coniecturis. In De coniecturis Cusanus obviously turns from a negative concept of the unsayable to a paradigmatic, which implies that he looks for principles of speaking of the unsayable and presents the idea of a divine language (divinaliter). However, he leaves this idea behind after De coniecturis, although he continues to create new concepts of the unsayable and incomprehensible. The intellectual language of absolute seeing is expressed in the subjunctive, i.e. conditionally. In order to describe the unsayable, Cusanus uses tautologies, the primary one of which is a concept of God, i.e. non aliud est non aliud quam non aliud (the non-other is non-other than the nonother). Wyller considers this the crucial point of the philosophy of Cusanus (De non aliud), described by the latter as the definition of definitions, i.e. the absolute definition. However, this definition is empty regarding its content. It demonstrates that God surpasses the coincidence of opposites (coincidentia oppositorum) and that he is “superunsayable” (superineffabilis), i.e. he is beyond what can be conceived or said. Nothing hence prevents us from speaking of him, provided that he is described as unsayable (= the paradigmatic concept of the unsayable). Here the mode of seeing is decisive. Cusanus in this context (and especially in his later literary production) uses modalities which concern possibility and necessity. His aim is to conduct any willing reader ahead on the way of life (philosophia mentalis). In De coniecturis II he describes the notion of human self-consciousness as the basis of spiritual mutuality in accordance with the humanistic tradition of his time. I mainly oppose the negatively determined concept of Christian mysticism presented by the German philosopher Kurt Flasch and prefer the presentation of Burkhard Mojsisch of the translogical and conjectural use of language in De coniecturis. In particular, I take account of the Scandinavian research, basically that of Johannes Sløk, Birgit H. Helander, Egil Wyller and Viggo Rossvær, who all consider the personal experience of God described by Cusanus a tacit precondition of his philosophy.

Gap junctions in the cardiovascular and immune systems

Gap junctions are clusters of intercellular channels directly connecting the cytoplasm of adjacent cells. These channels are formed by proteins named connexins and are present in all metazoan organisms where they serve diverse functions ranging from control of cell growth and differentiation to electric conduction in excitable tissues. In this overview we describe the presence of connexins in the cardiovascular and lympho-hematopoietic systems giving the reader a summary of the topics to be covered throughout this edition and a historical perspective of the discovery of gap junctions in the immune system.

Reporting on methods of subgroup analysis in clinical trials: a survey of four scientific journals

Results of subgroup analysis (SA) reported in randomized clinical trials (RCT) cannot be adequately interpreted without information about the methods used in the study design and the data analysis. Our aim was to show how often inaccurate or incomplete reports occur. First, we selected eight methodological aspects of SA on the basis of their importance to a reader in determining the confidence that should be placed in the author's conclusions regarding such analysis. Then, we reviewed the current practice of reporting these methodological aspects of SA in clinical trials in four leading journals, i.e., the New England Journal of Medicine, the Journal of the American Medical Association, the Lancet, and the American Journal of Public Health. Eight consecutive reports from each journal published after July 1, 1998 were included. Of the 32 trials surveyed, 17 (53%) had at least one SA. Overall, the proportion of RCT reporting a particular methodological aspect ranged from 23 to 94%. Information on whether the SA preceded/followed the analysis was reported in only 7 (41%) of the studies. Of the total possible number of items to be reported, NEJM, JAMA, Lancet and AJPH clearly mentioned 59, 67, 58 and 72%, respectively. We conclude that current reporting of SA in RCT is incomplete and inaccurate. The results of such SA may have harmful effects on treatment recommendations if accepted without judicious scrutiny. We recommend that editors improve the reporting of SA in RCT by giving authors a list of the important items to be reported.
