Point Of No Return: Dope Sick Love and Reindeerspotting as Documentaries of Addiction

In this postgraduate thesis the focus is on two documentary films, Renaud Brothers's Dope Sick Love (2005) and Joonas Neuvonen's Reindeerspotting (2010). In both of these films, addicts are on limelight. The directors of both films follow addicts and their everyday lives on streets with handheld cameras. This thesis will analyze and compare the narratives of these addicts. Do these documentaries affirm to the existing conventions, according to which representations of addicts and addiction are always either miraculous survival stories or stories, which always end up in utter decadence. The main questions this thesis proposes, are how addicts and their narratives are being handled in the two case study films, and how the drug cultures depicted in the films differ from each other. What changes between New York City and Rovaniemi, Northern Finland, and what remains the same. The academic and theoretical framework of this thesis consists of Susanna Helke's doctoral thesis Nanookin jälki, where the history of documentary films' methods and approaches are discussed. Additionally, the thinking is heavily informed by such poststructuralist writers as Roland Barthes, Michel Foucault, Louis Althusser, Stuart Hall and Chris Weedon.

Nanoparticle-Assisted Immunoassays for Point-of-Care Testing - With Specific Interest in Minimally Interference-Prone Assays for Cardiac Troponin I

Cardiac troponins (cTn) I and T are the current golden standard biochemical markers in the diagnosis and risk stratification of patients with suspected acute coronary syndrome. During the past few years, novel assays capable of detecting cTn‐concentrations in >50% of apparently healthy individuals have become readily available. With the emerging of these high sensitivity cTn assays, reductions in the assay specificity have caused elevations in the measured cTn levels that do not correlate with the clinical picture of the patient. The increased assay sensitivity may reveal that various analytical interference mechanisms exist. This doctoral thesis focused on developing nanoparticle‐assisted immunometric assays that could possibly be applied to an automated point‐of‐care system. The main objective was to develop minimally interference‐prone assays for cTnI by employing recombinant antibody fragments. Fast 5‐ and 15‐minute assays for cTnI and D‐dimer, a degradation product of fibrin, based on intrinsically fluorescent nanoparticles were introduced, thus highlighting the versatility of nanoparticles as universally applicable labels. The utilization of antibody fragments in different versions of the developed cTnI‐assay enabled decreases in the used antibody amounts without sacrificing assay sensitivity. In addition, the utilization of recombinant antibody fragments was shown to significantly decrease the measured cTnI concentrations in an apparently healthy population, as well as in samples containing known amounts of potentially interfering factors: triglycerides, bilirubin, rheumatoid factors, or human anti‐mouse antibodies. When determining the specificity of four commercially available antibodies for cTnI, two out of the four cross‐reacted with skeletal troponin I, but caused crossreactivity issues in patient samples only when paired together. In conclusion, the results of this thesis emphasize the importance of careful antibody selection when developing cTnI assays. The results with different recombinant antibody fragments suggest that the utilization of antibody fragments should strongly be encouraged in the immunoassay field, especially with analytes such as cTnI that require highly sensitive assay approaches.

Spectrally Tuned Lanthanide Photoluminescence for Point-of-Care Testing

Point-of-care (POC) –diagnostics is a field with rapidly growing market share. As these applications become more widely used, there is an increasing pressure to improve their performance to match the one of a central laboratory tests. Lanthanide luminescence has been widely utilized in diagnostics because of the numerous advantages gained by the utilization of time-resolved or anti-Stokes detection. So far the use of lanthanide labels in POC has been scarce due to limitations set by the instrumentation required for their detection and the shortcomings, e.g. low brightness, of these labels. Along with the advances in the research of lanthanide luminescence, and in the field of semiconductors, these materials are becoming a feasible alternative for the signal generation also in the future POC assays. The aim of this thesis was to explore ways of utilizing time-resolved detection or anti-Stokes detection in POC applications. The long-lived fluorescence for the time-resolved measurement can be produced with lanthanide chelates. The ultraviolet (UV) excitation required by these chelates is cumbersome to produce with POC compatible fluorescence readers. In this thesis the use of a novel light-harvesting ligand was studied. This molecule can be used to excite Eu(III)-ions at wavelengths extending up to visible part of the spectrum. An enhancement solution based on this ligand showed a good performance in a proof-of-concept -bioaffinity assay and produced a bright signal upon 365 nm excitation thanks to the high molar absorptivity of the chelate. These features are crucial when developing miniaturized readers for the time-resolved detection of fluorescence. Upconverting phosphors (UCPs) were studied as an internal light source in glucose-sensing dry chemistry test strips and ways of utilizing their various emission wavelengths and near-infrared excitation were explored. The use of nanosized NaYF :Yb3+,Tm3+-particles enabled the replacement of an external UV-light source with a NIR-laser and gave an additional degree of freedom in the optical setup of the detector instrument. The new method enabled a blood glucose measurement with results comparable to a current standard method of measuring reflectance. Microsized visible emitting UCPs were used in a similar manner, but with a broad absorbing indicator compound filtering the excitation and emission wavelengths of the UCP. This approach resulted in a novel way of benefitting from the non-linear relationship between the excitation power and emission intensity of the UCPs, and enabled the amplification of the signal response from the indicator dye.

The role of import intermediary companies in the Russian imports from the EU A case study of a Russian industrial company’s point of view on import intermediaries

The literature on agency suggests different implications for the use of export intermediaries. However, only few studies provide a view on import intermediaries. This thesis tries for its part to fill this research gap by studying the import intermediaries in the EU–Russia trade from a Russian industrial company’s point of view. The aim is to describe import intermediation and explain the need for import intermediary companies in the EU–Russia trade. The theoretical framework of this thesis originates from an article by Peng and York (2001), in which they study the performance of export intermediaries. This thesis applies resource-based theory, transaction cost theory and agency cost theory, following the idea of Peng and York. The resource-based theory approach is utilised for describing an ideal import intermediary company, and transaction cost theory provides a basis for understanding the benefits of using the services of import intermediary companies, while agency cost theory is applied in order to understand the risks the Russian industrial company faces when it decides to use the services of import intermediaries. The study is performed in the form of a case interview with a representative of a major Russian metallurgy company. The results of the study suggest that an ideal intermediary has the skills required specifically for the imports process, in order to save time and money of the principal company. The intermediary company helps reducing the amount of time the managers and the staff of the principal company use to make imports possible, thus reducing the salary costs and providing the possibility to concentrate on the company’s core competencies. The benefits of using the services of import intermediary companies are the reduced transaction costs, especially salary costs that are minimised because of the effectiveness and specialisation of import intermediaries. Intermediaries are specialised in the imports process and thus need less time and resources to organise the imports. They also help to reduce the fixed salary costs, because their services can be used only when needed. The risks of being misled by intermediaries are minimised by the competition on the import intermediary market. In case an intermediary attempts fraud, it gets replaced by its rival.

Biomarkkerit sepsiksen diagnostiikassa sekä Kvantitatiivisen prokalsitoniini-immunomäärityksen pystyttäminen ja optimointi point-of-care-ympäristöön

Termiä sepsis käytetään infektion aiheuttamasta yleisestä tulehdusreaktio-oireyhtymästä. Biokemiallinen merkkiaine eli biomarkkeri on aine, joka objektiivisesti mitattuna ja arvioituna toimii indikaattorina erottaen toisistaan normaalit biologiset prosessit ja patogeeniset prosessit. Lisäksi biomarkkeri saattaa osoittaa farmakologisen vasteen lääkehoidolle. Tutkielman kirjallisessa osassa on esitelty ja verrattu toisiinsa jo kliinisessä käytössä olevia sekä lupaavia, vielä tutkimusvaiheessa olevia, sepsiksen biomerkkiaineita. Lisäksi tutkielmassa on tarkasteltu sepsiksen todentamisen, tunnistamisen ja hoidon tulevaisuudennäkymiä. Prokalsitoniini (PCT) on eräs jo kliinisessä käytössä oleva sepsiksen biomerkkiaine. Tutkielman kokeellisessa osassa pystytettiin teho-osastoille suunnattu pikatesti PCT:n mittaamiseen aikaerotteista fluoresenssiteknologiaa hyödyntävälle AQT-järjestelmälle (DHR Finland Oy, Innotrac Diagnostics, Suomi). Järjestelmä mittaa 20–30 minuutissa biomerkkiainepitoisuuden. Tavoitteena oli löytää sopiva vasta-ainepari ja pystyttää kaksipuoleinen immunomääritys, jonka analyyttinen herkkyys on alle 0,02 ng/ml:ssa. Työssä tutkittiin biotinyloidun kokonaisen vasta-aineen ja paikkaspesifisesti biotinyloidun antigeenia sitovan fragmentin (engl. fragment antigen binding, Fab) toimivuutta sitojamolekyylinä. Lisäksi työssä verrattiin kahden eri leimamolekyylin, 9 hampaisen europiumkelaatin sekä Innotracissa kehitetyn tähtikelaatin, toimivuutta PCT-immunomäärityksessä. Vasta-aineiden mahdolliset ristireaktiot testattiin ja määritystä testattiin alustavasti eri näytematriiseissa. Työssä löydettiin 5 vasta-aineparia, joiden analyyttinen herkkyys oli alle 0,02 ng/ml:ssa. Aiemmin testattuja vasta-ainepareja parempi analyyttinen herkkyys johtui todennäköisesti yhden uuden leimavasta-aineen paremmasta affiniteetistä. Tähtikelaatilla leimatulla vasta-aineella analyyttinen herkkyys parani lähes viisinkertaisesti, kun sitä verrattiin 9-hampaisella euroopiumkelaatilla leimatun vasta-aineen määritykseen. Havaittiin myös, että Fab-fragmentilla mitattiin määrityksissä lähes kaksi kertaa suuremmat signaali-taustasuhteet, kun sitä verrattiin kokonaiseen vasta-aineeseen, tietyllä vasta-aineparilla. Tämä johtui luultavasti steeristen esteiden vähenemisestä. Näytematriisilla ei todettu olevan vaikutusta määritykseen, eikä ristireaktioita havaittu. Kehitetyn määrityksen suoriutumista verrattiin markkinoilla olevaan BRAHMS AG:n (Saksa) PCT-määritykseen käyttäen potilasnäytteitä. Korrelaatiokertoimet potilasnäytevertailuissa olivat 0,965–0,989 ja näytteiden mitatuissa pitoisuuksissa oli tasoero.

ATTITUDES TOWARD RUSSIAN CUSTOMERS IN THE FINNISH RETAIL TRADE SECTOR – A salesperson’s point of view

The amount of Russian tourists in Finland has increased significantly in the past years. The impact of Russian tourism to the Finnish retail trade sector is enormous, since Russian tourists often spend a lot of money particularly on shopping. Shopping tourism is mainly focused in the near border cities, such as Imatra and Lappeenranta, and in addition in Helsinki metropolitan area. The purpose of this study is to map the attitudes and perceptions of the sales personnel who are working in the Finnish retail trade sector towards Russian customers and to discover which elements affect these attitudes. The theories in this study are based on cultural elements and elements related to sales behavior and performance. Cultural differences between Finland and Russia, cultural distance and cultural intelligence form the cultural aspect of this study. Customer orientation vs. sales orientation (SOCO), adaptive selling, selling skills and job competency, salesperson’s affect and empathy toward customers, and job autonomy form the elements concerning sales behavior and performance. Furthermore, the attitude – behavior link, based on social psychology is addressed. A survey was conducted in two retail trade chains operating in Finland. These retail companies have stores and department stores in different geographical areas in Finland and the survey was conducted in altogether 19 cities. In addition to the theories that were discussed, two expert interviews were conducted in order to get a deeper understanding of the phenomenon at hand. Moreover the interviews helped in the formulation of the hypotheses and the questionnaire design. The questionnaires were sent directly to the stores, where they were placed so that they were available for the sales personnel. Altogether 487 usable responses were collected. The returned questionnaires were analyzed with IBM SPSS 21 statistics program. The results of this study indicated that the attitudes toward Russian customers are more negative compared to other foreign customers. However, the respondents’ attitudes toward and perceptions of Russian customers varied a lot. From the background variables age, education level, length of employment in current workplace, and length of experience in customer service had an effect on the attitudes of the respondents. In addition, the perceptions of Russian customers were more positive in the Eastern Finland compared to Helsinki metropolitan area. The cultural elements; cultural knowledge, cultural distance and cultural intelligence all affected the attitudes of the respondents. From the elements related to sales behavior and performance customer orientation, salesperson’s affect and empathy toward customers, and perceived job autonomy had an effect on the attitudes

R&D Performance Analysis: Case Studies on the Challenges and Promotion of the Evaluation and Measurement of R&D

Due to the intense international competition, demanding, and sophisticated customers, and diverse transforming technological change, organizations need to renew their products and services by allocating resources on research and development (R&D). Managing R&D is complex, but vital for many organizations to survive in the dynamic, turbulent environment. Thus, the increased interest among decision-makers towards finding the right performance measures for R&D is understandable. The measures or evaluation methods of R&D performance can be utilized for multiple purposes; for strategic control, for justifying the existence of R&D, for providing information and improving activities, as well as for the purposes of motivating and benchmarking. The earlier research in the field of R&D performance analysis has generally focused on either the activities and considerable factors and dimensions - e.g. strategic perspectives, purposes of measurement, levels of analysis, types of R&D or phases of R&D process - prior to the selection of R&Dperformance measures, or on proposed principles or actual implementation of theselection or design processes of R&D performance measures or measurement systems. This study aims at integrating the consideration of essential factors anddimensions of R&D performance analysis to developed selection processes of R&D measures, which have been applied in real-world organizations. The earlier models for corporate performance measurement that can be found in the literature, are to some extent adaptable also to the development of measurement systemsand selecting the measures in R&D activities. However, it is necessary to emphasize the special aspects related to the measurement of R&D performance in a way that make the development of new approaches for especially R&D performance measure selection necessary: First, the special characteristics of R&D - such as the long time lag between the inputs and outcomes, as well as the overall complexity and difficult coordination of activities - influence the R&D performance analysis problems, such as the need for more systematic, objective, balanced and multi-dimensional approaches for R&D measure selection, as well as the incompatibility of R&D measurement systems to other corporate measurement systems and vice versa. Secondly, the above-mentioned characteristics and challenges bring forth the significance of the influencing factors and dimensions that need to be recognized in order to derive the selection criteria for measures and choose the right R&D metrics, which is the most crucial step in the measurement system development process. The main purpose of this study is to support the management and control of the research and development activities of organizations by increasing the understanding of R&D performance analysis, clarifying the main factors related to the selection of R&D measures and by providing novel types of approaches and methods for systematizing the whole strategy- and business-based selection and development process of R&D indicators.The final aim of the research is to support the management in their decision making of R&D with suitable, systematically chosen measures or evaluation methods of R&D performance. Thus, the emphasis in most sub-areas of the present research has been on the promotion of the selection and development process of R&D indicators with the help of the different tools and decision support systems, i.e. the research has normative features through providing guidelines by novel types of approaches. The gathering of data and conducting case studies in metal and electronic industry companies, in the information and communications technology (ICT) sector, and in non-profit organizations helped us to formulate a comprehensive picture of the main challenges of R&D performance analysis in different organizations, which is essential, as recognition of the most importantproblem areas is a very crucial element in the constructive research approach utilized in this study. Multiple practical benefits regarding the defined problemareas could be found in the various constructed approaches presented in this dissertation: 1) the selection of R&D measures became more systematic when compared to the empirical analysis, as it was common that there were no systematic approaches utilized in the studied organizations earlier; 2) the evaluation methods or measures of R&D chosen with the help of the developed approaches can be more directly utilized in the decision-making, because of the thorough consideration of the purpose of measurement, as well as other dimensions of measurement; 3) more balance to the set of R&D measures was desired and gained throughthe holistic approaches to the selection processes; and 4) more objectivity wasgained through organizing the selection processes, as the earlier systems were considered subjective in many organizations. Scientifically, this dissertation aims to make a contribution to the present body of knowledge of R&D performance analysis by facilitating dealing with the versatility and challenges of R&D performance analysis, as well as the factors and dimensions influencing the selection of R&D performance measures, and by integrating these aspects to the developed novel types of approaches, methods and tools in the selection processes of R&D measures, applied in real-world organizations. In the whole research, facilitation of dealing with the versatility and challenges in R&D performance analysis, as well as the factors and dimensions influencing the R&D performance measure selection are strongly integrated with the constructed approaches. Thus, the research meets the above-mentioned purposes and objectives of the dissertation from the scientific as well as from the practical point of view.

A mathematical study of fuzzy logic; an algebraic approach

Fuzzy set theory and Fuzzy logic is studied from a mathematical point of view. The main goal is to investigatecommon mathematical structures in various fuzzy logical inference systems and to establish a general mathematical basis for fuzzy logic when considered as multi-valued logic. The study is composed of six distinct publications. The first paper deals with Mattila'sLPC+Ch Calculus. THis fuzzy inference system is an attempt to introduce linguistic objects to mathematical logic without defining these objects mathematically.LPC+Ch Calculus is analyzed from algebraic point of view and it is demonstratedthat suitable factorization of the set of well formed formulae (in fact, Lindenbaum algebra) leads to a structure called ET-algebra and introduced in the beginning of the paper. On its basis, all the theorems presented by Mattila and many others can be proved in a simple way which is demonstrated in the Lemmas 1 and 2and Propositions 1-3. The conclusion critically discusses some other issues of LPC+Ch Calculus, specially that no formal semantics for it is given.In the second paper the characterization of solvability of the relational equation RoX=T, where R, X, T are fuzzy relations, X the unknown one, and o the minimum-induced composition by Sanchez, is extended to compositions induced by more general products in the general value lattice. Moreover, the procedure also applies to systemsof equations. In the third publication common features in various fuzzy logicalsystems are investigated. It turns out that adjoint couples and residuated lattices are very often present, though not always explicitly expressed. Some minor new results are also proved.The fourth study concerns Novak's paper, in which Novak introduced first-order fuzzy logic and proved, among other things, the semantico-syntactical completeness of this logic. He also demonstrated that the algebra of his logic is a generalized residuated lattice. In proving that the examination of Novak's logic can be reduced to the examination of locally finite MV-algebras.In the fifth paper a multi-valued sentential logic with values of truth in an injective MV-algebra is introduced and the axiomatizability of this logic is proved. The paper developes some ideas of Goguen and generalizes the results of Pavelka on the unit interval. Our proof for the completeness is purely algebraic. A corollary of the Completeness Theorem is that fuzzy logic on the unit interval is semantically complete if, and only if the algebra of the valuesof truth is a complete MV-algebra. The Compactness Theorem holds in our well-defined fuzzy sentential logic, while the Deduction Theorem and the Finiteness Theorem do not. Because of its generality and good-behaviour, MV-valued logic can be regarded as a mathematical basis of fuzzy reasoning. The last paper is a continuation of the fifth study. The semantics and syntax of fuzzy predicate logic with values of truth in ana injective MV-algerba are introduced, and a list of universally valid sentences is established. The system is proved to be semanticallycomplete. This proof is based on an idea utilizing some elementary properties of injective MV-algebras and MV-homomorphisms, and is purely algebraic.
