The basis for this study was in poor attractiveness of the wood products industry among young people as a field to study and work in. The purpose was to produce new information of how to improve the relationship between young people and the wood products industry in order to better attract young people with different relational orientation. A survey was conducted among students of comprehensive schools and students of wood industry at vocational schools selected by systematic cluster sampling. The final sample consisted of 613 students. The study combined the theories and concepts of relationships, communication and trust of several disciplines. In addition, it applied theories of relationship marketing, stakeholders, publics, involvement and concepts of reputation and values. It studied the central relational elements in the form of antecedents, relationship state and its consequences. The study examined, how young people with different background and level of interest perceive wood industry as a field to study and work in from relational point of view, what are the central deficiencies in perceived relational elements and what are the public relations activities enhancing the relationship between wood industry and young people with less and high interest in the sector. The results indicate poor visibility of the wood industry among young people: unfamiliarity with the industry and unawareness of the opportunities to study in the field. It appeared that instead of increasing only information sharing, interactive communication in different forms is needed. The study also suggests that behaviors of the industry sector advancing perceived trustworthiness are of crucial importance. Moreover, the wood industry needs to pay attention to its behaviors and communication also among other stakeholder groups, especially the media, as reputation plays an important role in building up trust and satisfaction between young people and the sector. Finally, the less and highly interested young people were found to assess the relationship partly through different relational elements. In order to develop the relationship with highly interested young people they should be regarded clearly as future employees of the wood industry through activities affirming that they are desired and valued employees in the sector. Further, openness of information disclosure, whether concerning current situation or future prospects, seems to increase credibility and attractiveness of the wood industry. Highly interested young people were also found to appreciate socially responsible activities. The less interested young people seem to be insecure about the reliability of the wood industry as an employer, as well as, its ability and interest to invest in young people s skills. In addition,involvement in issues relevant for young people was found crucial in enhancing the relationship with the less interested young people.The conclusions of the study provide tools for enhancing the attractiveness of the wood industry among young people not only to the industry itself, but also to its advocates, teachers and student counselors of comprehensive and vocational schools, authorities and policy makers.

Eutrophication of the Baltic Sea is a serious problem. This thesis estimates the benefit to Finns from reduced eutrophication in the Gulf of Finland, the most eutrophied part of the Baltic Sea, by applying the choice experiment method, which belongs to the family of stated preference methods. Because stated preference methods have been subject to criticism, e.g., due to their hypothetical survey context, this thesis contributes to the discussion by studying two anomalies that may lead to biased welfare estimates: respondent uncertainty and preference discontinuity. The former refers to the difficulty of stating one s preferences for an environmental good in a hypothetical context. The latter implies a departure from the continuity assumption of conventional consumer theory, which forms the basis for the method and the analysis. In the three essays of the thesis, discrete choice data are analyzed with the multinomial logit and mixed logit models. On average, Finns are willing to contribute to the water quality improvement. The probability for willingness increases with residential or recreational contact with the gulf, higher than average income, younger than average age, and the absence of dependent children in the household. On average, for Finns the relatively most important characteristic of water quality is water clarity followed by the desire for fewer occurrences of blue-green algae. For future nutrient reduction scenarios, the annual mean household willingness to pay estimates range from 271 to 448 and the aggregate welfare estimates for Finns range from 28 billion to 54 billion euros, depending on the model and the intensity of the reduction. Out of the respondents (N=726), 72.1% state in a follow-up question that they are either Certain or Quite certain about their answer when choosing the preferred alternative in the experiment. Based on the analysis of other follow-up questions and another sample (N=307), 10.4% of the respondents are identified as potentially having discontinuous preferences. In relation to both anomalies, the respondent- and questionnaire-specific variables are found among the underlying causes and a departure from standard analysis may improve the model fit and the efficiency of estimates, depending on the chosen modeling approach. The introduction of uncertainty about the future state of the Gulf increases the acceptance of the valuation scenario which may indicate an increased credibility of a proposed scenario. In conclusion, modeling preference heterogeneity is an essential part of the analysis of discrete choice data. The results regarding uncertainty in stating one s preferences and non-standard choice behavior are promising: accounting for these anomalies in the analysis may improve the precision of the estimates of benefit from reduced eutrophication in the Gulf of Finland.

The aim of this study has been to discern what Manas Buthelezi (1935-), a black South African Lutheran theologian and later also a bishop, regards as the requirements a church has to fulfill in order to be credible in the apartheid society. Buthelezi’s dissertation and several articles written between the years 1968 and 1993 are the sources of this study. Also the lectures held in Heidelberg in 1972 are referred to. Systematic analysis is the method used. The question of the credibility of the church is studied through three concepts that play an important role in Buthelezi’s ecclesiological thought, namely the wholeness of life, incarnation and liberation. The notion of the wholeness of life stems from the African tradition. Buthelezi takes the concept into the Christian church: the church should realize that God is the Creator of all life and Christ the lord of every aspect of human existence. Life is one entity coram Deo. However, the church is not to become the world; solidarity between the two must remain critical as the church is also called to play a prophetic role in the society. The church is in an open relationship with the world. It has a unique message of forgiveness and reconciliation. Nevertheless, the message is not a possession of the church but it is addressed to the whole world. The meaning of incarnation comes close to that of the wholeness of life. Following the example of Christ’s incarnation, the church must become human in the reality of the people. The church in Soweto is to become the people of Soweto, that is, the church must become as vulnerable as the people are. An incarnate church cannot be immune to the oppression that people experience, because the people are the church. The church is therefore bound to suffer. Buthelezi’s theology of the cross is pragmatic: the suffering of the church aims at the liberation of the oppressed. At times the physical presence of the church by the side of the suffering people is the only way to preach the incarnate gospel. In the South Africa of the late 1960s onwards the liberation of the oppressed black people was high on the agenda of Black Theology. As a leader of the early South African Black Theology, Buthelezi is concerned about the racial injustice in his country. He urges the churches to join the struggle against it as one people of God. The notions of liberation and the wholeness of life emerge in Buthelezi’s holistic understanding of liberation that involves the inner liberation of the black spirit and the liberation of the economic, social and political aspects of life. Interpreting Tillich’s correlation method in the South African situation, and also paralleling other liberation theologians, Buthelezi takes the existential situation of the people as the starting point for liberation. The gospel has to respond to the existential questions of people. The church is called to work for the liberation of society but it must also be liberated itself. Buthelezi initiated the LWF statement on the status confessionis in South Africa (1977). In line with the statement, he calls for church unity on the human level. For the unity to be true, it has to be experienced on the grassroots’ level. All the three concepts covered urge the church to come down from any ivory tower and out of any spiritual haven it might hide in. A lot of the credibility of the church derives from the behavior of the people. Buthelezi’s concentration on how the people who constitute the church should live their faith leaves less attention to how God constitutes the church. I have labeled Buthelezi’s understanding of the church existential-Christocentric due to the emphasis he lays on the need of the church to take the existential situation of the people seriously and on the other hand, on Christ as the exemplar for the church.

Tutkimuksen keskeinen tehtävä on selvittää, mikä on dokumentoinnin merkitys lastensuojelun sosiaalityön tiedonmuodostuksessa ja ammattikäytännöissä. Asiakirjateksteistä koostuvaa tutkimusaineistoa tarkastellaan kolmesta eri suunnasta kysymällä: 1)Miten asiakirjoja kirjoitetaan? 2) Mitä asiakirjoihin kirjoitetaan? 3) Miksi asiakirjoja kirjoitetaan niin kuin kirjoitetaan? Tutkimusaineisto muodostuu lastensuojelun sosiaalityöntekijöiden laatimista asiakastietojärjestelmään tallennetuista muistiinpanoista ja huostaanottopäätöksistä. Tutkimukseen on valittu 20 huostaanotetun eri-ikäisen lapsen ja heidän perheensä asiakirjat yhteensä 1613 asiakirjatulostussivua. Tekstit ajoittuvat vuodesta 1989 vuoteen 2000. Tutkimusmenetelmä on diskurssianalyyttinen ja tukeutuu Fairclough`n (1997)esittämään kolmiulotteiseen malliin, jossa diskurssi määritellään tekstin, käytäntöjen ja sosiokulttuurisen ympäristön suhteeksi. Diskurssianalyysi on näiden rakenteiden ja niiden välisten suhteiden kuvaamista, tulkintaa ja selittämistä. Fairclough’n mallia mukaillen tutkimuksen analyysi koostuu retoriikan ja tematiikan analyyseistä sekä pragmatiikan näkökulman sisältävästä tarkastelusta. Asiakirjatekstien pilkkominen puhujakategorioihin osoitti tekstien olevan moniäänisiä, useiden henkilöiden näkemyksiä ja mielipiteitä sisältäviä tekstipintoja. Retoriikan analyysi näytti, että lastensuojelun sosiaalityön asiakirjat sisältävät paljon dynaamisia kuvauksia työstä. Asiakirjojen kirjoittaminen moniäänisiksi tuo tekstiin uskottavuutta, ja se on myös yksi retorinen vaikuttamiskeino. Tematiikan tarkastelu osoitti,että asiakirjojen sisällölliset teemat (lapsen hoiva, arjen hallinta, yhteistyö ja päihteiden käyttö) ja kokemukselliset teemat (huoli, vastuu, yhteys ja moraali) toistuvat sisäkkäisinä ja päällekkäisinä säikeinä dynaamisesti vaihdellen. Sosiaalityöntekijät kirjaavat teksteihin monia yhtäaikaisia teemoja, joiden avulla rakentavat ammatillista ymmärrystä kyseessä olevasta tilanteesta. Asiakirjojen tutkiminen pragmatiikan suunnasta toi esiin, kirjoittamisen ja lukemisen kontekstiulottuvuudet sekä tiedonmuodostusprosessin. Asiakirjojen laatiminen on osa sosiaalityön käytäntöjä. Se on myös keskeinen alue ammattikunnan yhteisen ammatillisen ymmärryksen luomisessa ja ylläpitämisessä. Muistiinpanot, huostaanottopäätökset ja lakitekstit ovat intertekstuaalisia. Lastensuojelun sosiaalityön asiakirjojen tutkiminen on avannut uusia mahdollisuuksia ymmärtää sosiaalityön dokumentointiprosessia, merkitystä ja roolia sekä tiedonmuodostuksen dynamiikkaa. Tekstien kirjoittaminen, niiden lukeminen, tietojen siirtäminen ja asiakkaan kuuleminen samoin kuin kuulemisen kirjaaminen ovat sosiaalityön dokumentoinnin keskeisiä haasteita. Tutkimus pyrkii avaamaan ymmärrystä asiakirjatekstien monivivahteiseen ja dynaamiseen maailmaan ja siten myös sosiaalityön dokumentoinnin arkeen. Tarkastelut mahdollistavat työn kehittämisen erityisesti sosiaalityön asiakasvaikuttavuuden mittaamisen ja parantamisen suuntaan. Asiakirjoissa ilmenevä tiedonmuodostuksen dynamiikka syntyy kirjoittamiskäytäntöjen, kirjoittamisen ja lukemisen sekä toimintakäytäntöjen yhteisessä alueessa. Avainsanat: sosiaalityö, lastensuojelu, dokumentointi, asiakirja, diskurssianalyysi, tiedonmuodostus.

A search for a narrow diphoton mass resonance is presented based on data from 3.0 fb^{-1} of integrated luminosity from p-bar p collisions at sqrt{s} = 1.96 TeV collected by the CDF experiment. No evidence of a resonance in the diphoton mass spectrum is observed, and upper limits are set on the cross section times branching fraction of the resonant state as a function of Higgs boson mass. The resulting limits exclude Higgs bosons with masses below 106 GeV at a 95% Bayesian credibility level (C.L.) for one fermiophobic benchmark model.

We present a search for a Higgs boson decaying to two W bosons in ppbar collisions at sqrt(s)=1.96 TeV center-of-mass energy. The data sample corresponds to an integrated luminosity of 3.0 fb-1 collected with the CDF II detector. We find no evidence for production of a Higgs boson with mass between 110 and 200 GeV/c^2, and determine upper limits on the production cross section. For the mass of 160 GeV/c^2, where the analysis is most sensitive, the observed (expected) limit is 0.7 pb (0.9 pb) at 95% Bayesian credibility level which is 1.7 (2.2) times the standard model cross section.

We report on a search for the supersymmetric partner of the bottom quark produced from gluino decays in data from 2.5 fb-1 of integrated luminosity collected by the Collider Detector at Fermilab at sqrt(s)=1.96 TeV. Candidate events are selected requiring two or more jets and large missing transverse energy. At least two of the jets are required to be tagged as originating from a b quark to enhance the sensitivity. The results are in good agreement with the prediction of the standard model processes, giving no evidence for gluino decay to sbottom quarks. This result constrains the gluino-pair-production cross section to be less than 40fb at 95% credibility level for a gluino mass of 350 GeV.

We present a search for the standard model Higgs boson produced with a Z boson in 4.1 fb^-1 of data collected with the CDF II detector at the Tevatron. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electrons or muons, we set 95% credibility level upper limits on the ZH production cross section times the H -> b bbar branching ratio. Improved analysis methods enhance signal sensitivity by 20% relative to previous searches beyond the gain due to the larger data sample. At a Higgs boson mass of 115 GeV/c^2 we set a limit of 5.9 times the standard model value.

We report results from a search for the lepton flavor violating decays $B^0_{(s)}\to e^+\mu^-$, and the flavor-changing neutral-current decays $B^0_{(s)} \to e^+ e^-$. The analysis uses data corresponding to ${\rm 2 fb^{-1}}$ of integrated luminosity of $p \bar{p}$ collisions at $\sqrt{s}=1.96 {\rm TeV}$ collected with the upgraded Collider Detector (CDF II) at the Fermilab Tevatron. The observed number of $B^0_{(s)}$ candidates is consistent with background expectations. The resulting Bayesian upper limits on the branching ratios at 90% credibility level are $\mathcal{B}(B^0_s \to e^{+}\mu^{-}) e^{+}\mu^{-})e^{+}\mu^{-}) 47.8 {\rm TeV/c^2}$, and ${M_{LQ}}(B^0\to e^+ \mu^-) > 59.3 {\rm TeV/c^2}$, at 90% credibility level.

A search for high-mass resonances in the $e^+e^-$ final state is presented based on 2.5 fb$^{-1}$ of $\sqrt{s}=$1.96 TeV $p\bar{p}$ collision data from the CDF II detector at the Fermilab Tevatron. The largest excess over the standard model prediction is at an $e^+e^-$ invariant mass of 240 GeV/$c^2$. The probability of observing such an excess arising from fluctuations in the standard model anywhere in the mass range of 150--1,000 GeV/$c^2$ is 0.6% (equivalent to 2.5 $\sigma$). We exclude the standard model coupling $Z'$ and the Randall-Sundrum graviton for $k/\overline{M}_{Pl}=0.1$ with masses below 963 and 848 GeV/$c^2$ at the 95% credibility level, respectively.

Purpose – This research paper studies how the strategy of repositioning enables marketers to communicate CSR as their brand’s differentiating factor. It aims at understanding how consumer perceptions can be managed to generate brand value through corporate brand repositioning when CSR is the differentiating factor. The purpose of this paper is to answer the following research question: How can consumer perceptions be managed to generate brand value through corporate brand repositioning when CSR is the differentiating factor? The two research objectives were: 1. to build a model, which describes the different components of consumer perceptions involved in generation of brand value through repositioning when CSR is the differentiating factor, 2. to identify the most critical components in the context of the case company, IKEA for generation of brand value during the process of corporate brand repositioning Design/methodology/approach – This paper is based on the literature review covering the logic of brand value generation, repositioning strategy and consumer perceptions connected to CSR activities. A key concept of the positioning theory, the brand’s differentiating factor, was explored. Previous studies have concluded that desirability of the differentiating factor largely determines the level of brand value-creation for the target customers. The criterion of desirability is based on three dimensions: relevance, distinctiveness and believability. A model was built in terms of these desirability dimensions. This paper takes a case study approach where the predefined theoretical framework is tested using IKEA as the case company. When developing insights on the multifaceted nature of brand perceptions, personal interviews and individual probing are vital. They enable the interviewees to reflect on their feelings and perceptions with their own words. This is why the data collection was based on means-end type of questioning. Qualitative interviews were conducted with 12 consumers. Findings – The paper highlights five critical components that may determine whether IKEA will fail in its repositioning efforts. The majority of the critical components involved believability perceptions. Hence, according to the findings, establishing credibility and trustworthiness for the brand in the context of CSR seems primary. The most critical components identified of the believability aspect were: providing proof of responsible codes of conduct via conducting specific and concrete CSR actions, connecting the company’s products and the social cause, and building a linkage between the initial and new positioning while also weakening the old positioning. Originality/value – Marketers’ obligation is to prepare the company for future demands. Companies all over the globe have recognized the durable trend of responsibility and sustainability. Consumer´s worry about the environmental and social impact of modern lifestyles is growing. This is why Corporate Social Responsibility (CSR) provides brands an important source of differentiation and strength in the future. The strategy of repositioning enables marketers to communicate CSR as their brand’s differentiating factor. This study aimed at understanding how consumer perceptions can be managed to generate brand value through corporate brand repositioning when CSR is the differentiating factor.

Previous research has been inconclusive regarding the impact of those who invest in entrepreneurs. Consider for a moment how potentially important they are to entrepreneurs. They for example decide who deserves funding, how much time they contribute to their portfolio firms, how they grant entrepreneurs access to their networks, and help entrepreneurs acquire additional funding. In sum, investors potentially have a great impact on the success of entrepreneurs. It is therefore important that we better understand the environment, relationships and context in which parties operate. This thesis contains five articles that explore investors’ and entrepreneurs’ relationships from various viewpoints, in theoretical frameworks, and use a variety of data and research methods. The first article is a literature review that summarises what we know of venture capital, business angel and corporate venture capital funding. The second article studies the entrepreneurs’ investor selection process, its consequences, and identifies key factors that influence the process. Earlier, the common approach has been to concentrate research on the investors’ selection policy, not the entrepreneurs’. The data and conclusions are based on multiple case studies. The article analyses how entrepreneurs can ensure that they get the best possible investor, when it is possible for an entrepreneur to select an investor, and what are the consequences of investor selection. The third article employs power constructs (dependency, power balance/imbalance, power sources) and analyses their applicability in the investor-entrepreneur relationship. Power constructs are extensively studied and utilised in the management and organisation literature. In entrepreneur investor relationships, power aspects are rarely analysed. However, having the ability to “get others to do things they would not otherwise do” is a very common factor in the investor-entrepreneur relationship. Therefore, employing and analysing the applicability of power constructs in this setting is well founded. The article is based on a single case study but suggests that power constructs could be applicable and consequently provide additional insights into the investor-entrepreneur relationship. The fourth article studies the role of advisors in the venture capital investment process and analyses implications for research and practice, particularly from the entrepreneurs’ perspective. The common entrepreneurial finance literature describes the entrepreneur-investor relationship as linear and bilateral. However, it was discovered that advisors may influence the relationship. In this article, the role of advisors, operating procedures and advisors’ impact on different parties is analysed. The fifth article concentrates on investors’ certification effect. The article measures and demonstrates that venture capital investment is likely to increase the credibility (in terms of media attention) of early stage firms, those that most often need additional credibility. Understanding investor certification can affect how entrepreneurs evaluate investment offers and how investors can make their offers appear more lucrative.

The purpose of this research was to investigate the role of electronic word of mouth (eWOM) in shaping consumer attitudes towards various products and services with concentration on the consumer attitude change. eWOM has long been proven to play an important role in influencing consumer attitudes and has been researched from a variety of perspectives. This study attempts to look deeper into the process of consumer attitude change by applying as the central theory of the study the Elaboration Likelihood Model of Persuasion by Petty and Cacioppo. In the processes of examining the background academic and empirical research the Internet and Web 2.0 are closely depicted in order to understand how throughout the past centuries technology allowed the rise of various mediums where consumers can not only share their opinions online about products and services but also communicate with other consumers. Manuel Castel’s Internet Galaxy, Gildin’s, Carl and Noland’s, Hennig-Thurau, Gwinner, Walsh and Gremler’s researches on eWOM are the central works that helped to shape both the theoretical and empirical parts of this study. The mixed method approach was chosen as a research method for this study. An online survey was conducted via the Surveymonkey.com platform and eight qualitative in-depth interviews were conducted. The results of the study show that central route queues as text quality and text argumentativeness are more prominent among the research subjects and the peripheral route queues: source credibility and source expertise did not show considerable significance. Also more experience and participation consumers have with user-rating websites and applications more inclined they are to elaborate on the central route cues and are more likely to search for opinions that they consider rational and credible. Also these respondents are less inclined to search for ratings that confirm their existing beliefs about products or services. Less experience/participation they have about eWOM more likely they are to search for reviews confirmatory to their own.
