Innovation is the word of this decade. According to innovation definitions, without positive sales impact and meaningful market share the company’s product or service has not been an innovation. Research problem of this master thesis is to find out what is the innovation process of complex new consumer products and services in new innovation paradigm. The objective is to get answers to two research questions: 1) What are the critical success factors what company should do when it is implementing the paradigm change in mass markets consumer business with complex products and services? 2) What is the process or framework one firm could follow? The research problem is looked from one company’s innovation creation process, networking and organization change management challenges point of views. Special focus is to look the research problem from an existing company perspective which is entering new business area. Innovation process management framework of complex new consumer products and services in new innovation paradigm has been created with support of several existing innovation theories. The new process framework includes the critical innovation process elements companies should take into consideration in their daily activities when they are in their new business innovation implementing process. Case company location based business implementation activities are studied via the new innovation process framework. This case study showed how important it is to manage the process, look how the target market and the competition in it is developing during company’s own innovation process, make decisions at right time and from beginning plan and implement the organization change management as one activity in the innovation process. In the end this master thesis showed that all companies need to create their own innovation process master plan with milestones and activities. One plan does not fit all, but all companies can start their planning from the new innovation process what was introduced in this master thesis.

This thesis is concerned with the philosophical grammar of certain psychiatric concepts, which play a central role in delineating the field of psychiatric work. The concepts studied are ‘psychosis’, ‘delusion’, ‘person’, ‘understanding’ and ‘incomprehensibility’. The purpose of this conceptual analysis is to provide a more perspicuous view of the logic of these concepts, how psychiatric work is constituted in relation to them, and what this tells us about the relationships between the conceptual and the empirical in psychiatric concepts. The method used in the thesis is indebted primarily to Ludwig Wittgenstein’s conception of philosophy, where we are urged to look at language uses in relation to practices in order to obtain a clearer overview of practices of interest; this will enable us to resolve the conceptual problems related to these practices. This questioning takes as its starting point the concept of psychosis, a central psychiatric concept during the twentieth century. The conceptual analysis of ‘psychosis’ shows that the concept is logically dependent on the concepts of ‘understanding’ and ‘person’. Following the lead found in this analysis, the logic of person-concepts in psychiatric discourse is analysed by a detailed textual analysis of a psychiatric journal article. The main finding is the ambiguous uses of ‘person’, enabling a specifically psychiatric form of concern in human affairs. The grammar of ‘understanding’ is then tackled from the opposite end, by exploring the logic of the concept of ‘incomprehensibility’. First, by studying the DSM-IV definition of delusion it is shown that its ambiguities boil down to the question of whether psychiatric practice is better accounted for in terms of the grammar of ‘incorrectness’ or ‘incomprehensibility’. Second, the grammar of ‘incomprehensibility’ is further focused on by introducing the distinction between positive and negative conceptions of ‘incomprehensibility’. The main finding is that this distinction has wide-ranging implications for our understanding of psychiatric concepts. Finally, some of the findings gained in these studies are ‘put into practice’ in studying the more practical question of the conceptual and ethical problems associated with the concept of ‘prodromal symptom of schizophrenia’ and the agenda of early detection and intervention in schizophrenia more generally.

This study examines the place of The Church of Jesus Christ of Latter-day Saints (commonly known as the Mormon church) in the Russian Grand Duchy of Finland between the years 1840 and 1900. Attention is put on both the internal workings of the movement and the reactions of society. Theoretical insight is gained through the concepts of social construction and religious economies. Mormon image formation in Finland began by 1840 through newspaper reports on activities abroad and through essays on the faith’s history and doctrine. Mormons are mentioned almost 3,500 times in Finnish newspapers between 1840 and 1900, and at least twelve unique book titles sold in the country were explicitly devoted to discussing Mormonism. Most of the publicity was derived from foreign sources. Discourse analysis of this textual corpus shows a hegemonic discourse that combined themes such as fraud, deception, and theocracy in explaining the Mormon movement. Accompanied by plural marriage, these themes contributed to the construction of a strongly negative image of Mormonism already before the first missionaries arrived in 1875. In a society with a stringently regulated religious economy, this image contributed to a high level of resistance by civil authorities and Lutheran clergy. Twenty-five Mormon missionaries worked in Finland between 1875 and 1900, with a concentrated effort taking place between 1875 and 1889. At least 78 persons converted, mostly in the coastal areas among the Swedish-speaking minority population. Nine percent emigrated to Utah, 36% were excommunicated, others fell into oblivion, while still others clung to their new faith. The work was led from Sweden, with no stable church organization emerging among the isolated pockets of converts. Mormonism’s presence was thus characterized by private or small-group religiosity rather than a vibrant movement. The lack of religious community, conversation, and secondary socialization eventually caused the nineteenth-century manifestation of Finnish Mormonism to die out. Only one group of converts was perpetuated past World War II, after which large-scale proselytizing began.

Spermatogenesis, i.e sperm production in the seminiferous tubules of the testis, is a complex process that takes over one month to complete. Life-long ability of sperm production ultimately lies in a small population of undifferentiated cells, called spermatogonial stem cells (SSCs). These cells give rise to differentiating spermatogonia, which are committed to mature into spermatozoa. SSCs represent a heterogeneous population of cells and many aspects of their basic biology are still unknown. Understanding the mechanisms behind the cell fate decision of these cells is important to gain more insights into the causes of infertility and testis cancer. In addition, an interesting new aspect is the use of testis-derived stem cells in regenerative medicine. Our data demonstrated that adult mouse testis houses a population of Nanog-expressing spermatogonia. Based on mRNA and protein analysis these cells are enriched in stage XII of the mouse seminiferous epithelial cycle. The cells derived from this stage have the highest capacity to give rise to ES cell-like cells which express Oct4 and Nanog. These cells are under tight non- GDNF regulation but their fate can be dictated by activating p21 signalling. Comparative studies suggested that these cells are regulated like ES cells. Taken together these data imply that pluripotent cells are present in the adult mammalian testis. CIP2A (cancerous inhibitor of PP2A) has been associated with tumour aggressiveness and poor prognosis. In the testis it is expressed by the descendants of stem cells, i.e. the spermatogonial progenitor cells. Our data suggest that CIP2A acts upstream of PLZF and is needed for quantitatively normal spermatogenesis. Classification of CIP2A as a cancer/testis gene makes it an attractive target for cancer therapy. Study on the CIP2A deficient mouse model demonstrates that systemic inhibition of CIP2A does not severely interfere with growth and development or tissue or organ function, except for the spermatogenic output. These data demonstrate that CIP2A is required for quantitatively normal spermatogenesis. Hedgehog (Hh) signalling is involved in the development and maintenance of many different tissues and organs. According to our data, Hh signalling is active at many different levels during rat spermatogenesis: in spermatogonia, spermatocytes and late elongating spermatids. Localization of Suppressor of Fused (SuFu), the negative regulator of the pathway, specifically in early elongating spermatids suggests that Hh signalling needs to be shut down in these cells. Introduction of Hh signalling inhibitor resulted in an increase in germ cell apoptosis. Follicle-stimulating hormone (FSH) and inhibition of receptor tyrosine kinases resulted in down-regulation of Hh signalling. These data show that Hh signalling is under endocrine and paracrine control and it promotes germ cell survival.

According to several surveys and observations, the percentage of successfully conducted IT projects without over-budgeting and delays in time schedule are extremely low. Many projects also are evaluated as failures in terms of delivered functionality. Nuldén (1996) compares IT projects with bad movies; after watching for 2 hours, one still tries to finish it even though one understands that it is a complete waste of time. The argument for that is 'I've already invested too much time to terminate it now'. The same happens with IT projects: sometimes the company continues wasting money on these projects for a long time, even though there are no expected benefits from these projects. Eventually these projects are terminated anyway, but until this moment, the company spends a lot. The situation described above is a consequence of “escalation of commitment” - project continuation even after a manager receives negative feedback of the project’s success probability. According to Keil and Mähring (2010), even though escalation can occur in any type of project, it is more common among complex technological projects, such as IT projects. Escalation of commitment very often results in runaway projects. In order to avoid it, managers use de-escalation strategies, which allow the resources to be used in more effective. These strategies lead to project termination or turning around, which stops the flow of wasted investments. Numbers of researches explore escalation of commitment phenomena based on experiments and business cases. Moreover, during the last decade several frameworks were proposed for de-escalation strategy. However, there is no evidence of successful implementation of the de-escalation of commitment strategy in the literature. In addition, despite that fact that IT project management methodologies are widely used in the companies, none of them cover the topic of escalation of commitment risks. At the same time, there are no researches proposing the way to implement de-escalation of commitment strategy into the existing project management methodology The research is focused on a single case of large ERP implementation project by the consulting company. Hence, the main deliverables of the study include suggestions of improvement in de-escalation methods and techniques in the project and in the company. Moreover, the way to implement these methods into existing project management methodology and into the company general policies is found.

Strikes provide a current, fresh but also a seldom-addressed issue to study from economic sciences perspective. This study provides to filling this research gap by trying to identify attitudes towards strikes that can be found inside organizations. The research problem this study then sets out to answer is: “What kinds of attitudes exist inside organizations towards industrial actions and how attitudes vary between labour, management and human resources?” This study has been planned with a view to test how qualitative attitudinal research, as a method, is suited to studying a phenomenon such as strike. At the heart of this research approach lies an assumption linked to rhetoric social psychology, that attitude is a phenomenon that can be identified in argumentation. For this research 10 semi-structured interviews in 4 organizations were conducted utilizing statements and pictures as stimulants for discussion. The material was transcribed and analysed following the two levels, categorical and interpretive, demanded by the chosen method. Altogether five attitudes were discovered; three of them negative, one indifferent and one positive by nature. The negative attitudes of unfairness, failure and personification towards strikes represented the side of strikes that was perhaps the most anticipated, portraying the contradictions between employees and employer. The attitude of ordinariness, which portrayed indifference, and the positive attitude of change however, were more unanticipated findings. They reflect shared understanding and trust between conflict parties. The utilization of qualitative attitudinal approach to study strikes was deemed successful. The results of this study support prior literature on workplace conflicts for example in regards of the definition of conflict and typologies conflicts. In addition the multifaceted nature of strikes can be perceived as one statement supported by this study. It arises in the nature of the attitudes, the diversity of discussion themes during the interviews as well as in the extent of possible theories to apply.

The world has witnessed a great deal of globalization and a rise in international activities in recent years compared to decades ago. This has contributed to an upsurge in competition among manufacturing firms resulting in the use of different marketing strategies to survive. Packaging is one of the tools that has been used by marketers to make products different and appealing to both local and international customers. The purpose of this research work was to investigate more on packaging as a marketing tool and how internationalization affects the decisions management makes in relation to it. To this effect, a qualitative research was conducted using five manufacturing companies as case studies and data collected through semi-structured interviews and also personal observation. Secondary sources were also used in order to get deeper insight into the case companies under study. The study revealed that there are many advantages that internationalization provides firms. The general revelations made by the firms that were researched did not point to a negative impact of internationalization on their packaging decisions. Internationalization has provided positive improvements on their packaging and made them more competitive. This proves that for packaging decisions to improve better, one key enabler will be exposure to the international environment since it provides a wider array of options for package improvements for firms.

The aim of this thesis was to examine how aquatic organisms, such as fish, behave in an altered environmental condition. Many species of fish use vision as their primary tool to gain information about their surrounding environment. The visual conditions of aquatic habitats are often altered as a result of anthropogenic disturbance, such as eutrophication that initiates algal turbidity. In general, turbidity reduces the visibility and can be hypothesized to have an influence on the behaviour of fish. I used the three-spined stickleback (Gasterosteus aculeatus) as a model species and conducted four studies in the laboratory to test how algal turbidity affects its behaviour. In this thesis, two major behavioural aspects are discussed. The first is antipredator behaviour. In study I, the combined effects of turbidity and shoot density on habitat choice (shelter vs open) behaviour was tested on a group of sticklebacks (20 fish) in the presence and absence of piscivorous perch (Perca fluviatilis). In study II, I examined the behavioural responses of feeding sticklebacks when they were exposed to the sudden appearance of an avian predator (the silhouette of a common tern, Sterna hirundo). The study was done in turbid and clear water using three different groups sizes (1, 3 and 6 fish). The second aspect is foraging behaviour. Study III & IV focused on the effects of algal turbidity on the foraging performance of sticklebacks. In study III, I conducted two separate experiments to examine the effects of turbidity on prey consumption and prey choice of sticklebacks. In this experiment turbidity levels and the proportion of large and small prey (Daphnia spp.) were manipulated. In study IV, I studied whether a group of six sticklebacks can distribute themselves according to food input at two feeding stations in a way that provided each fish with the same amount of food in clear and turbid water. I also observed whether the fish can follow changes in resource distribution between the foraging patches. My results indicate an overall influence of algal turbidity on the antipredator and foraging behaviour of sticklebacks. In the presence of a potential predator, the use of the sheltered habitat was more pronounced at higher turbidity. Besides this, sticklebacks reduced their activity levels with predator presence at higher turbidity and shoot density levels, suggesting a possible antipredator adaptation to avoid a predator. When exposed to a sudden appearance of an avian predator, sticklebacks showed a weaker antipredator response in turbid water, which suggests that turbidity degrades the risk assessment capabilities of sticklebacks. I found an effect of group size but not turbidity in the proportion of sticklebacks that fled to the shelter area, which indicates that sticklebacks are able to communicate among group members at the experimental turbidity levels. I found an overall negative effect of turbidity on food intake. Both turbidity and changes in the proportion of prey sizes played a significant role in a stickleback’s prey selection. At lower turbidity levels (clear <1 and 5 NTU) sticklebacks showed preferences for large prey, whereas in more turbid conditions and when the proportion of large to small prey increased sticklebacks became increasingly random in their prey selection. Finally, my results showed that groups of sticklebacks disperse themselves between feeding stations according to the reward ratios following the predictions of the ideal free distribution theory. However, they took a significantly longer time to reach the equilibrium distribution in turbid water than in clear water. In addition, they showed a slower response to changes in resource distribution in a turbid environment. These findings suggest that turbidity interferes with the information transfer among group foragers. It is important to understand that aquatic animals are often exposed to a degraded environment. The findings of this thesis suggest that algal turbidity negatively affects their behavioural performance. The results also shed light on the underlying behavioural strategies of sticklebacks in turbid conditions that might help them adapt to an altered environmental situation and increase their survival. In conclusion, I hold that although algal turbidity has detrimental effects on the antipredator and foraging behaviour of sticklebacks, their behavioural adjustment might help them adapt to a changing environment.

Global climate change and intentional climate modification, i.e. geoengineering include various ethical problems which are entangled as a complex ensemble of questions regarding the future of the biosphere. The possibilities of catastrophic effects of climate change which are also called “climate emergency” have led to the emergence of the idea of modifying the atmospheric conditions in the form of geoengineering. The novel issue of weather ethics is a subdivision of climate ethics, and it is interested in ethical and political questions surrounding weather and climate control and modification in a restricted spatio-temporal scale. The objective of geoengineering is to counterbalance the adverse effects of climate change and its diverse corollaries in various ways on a large scale. The claim of this dissertation is that there are ethical justifications to claim that currently large-scale interventions to the climate system are ethically questionable. The justification to pursue geoengineering on the basis of considering its pros and cons, is inadequate. Moral judgement can still be elaborated in cases where decisions have to be made urgently and the selection of desirable choices is severely limited. The changes needed to avoid severe negative impacts of climate change requires commitment to mitigation as well as social changes because technical solutions cannot address the issue of climate change altogether. The quantitative emphasis of consumerism should shift to qualitative focus on the aspiration for simplicity in order to a move towards the objective of the continuation of the existence of humankind and a flourishing, vital biosphere.

Keratins (K) are cytoskeletal proteins mainly expressed in the epithelium and constitute the largest subgroup of intermediate filaments (IFs). Simple epithelial keratins (SEKs) K7-K8 and K18-K20 are the major IF elements in the colon. SEK mutations are known to cause around 30 human diseases, mainly affecting liver and skin. However, so far no strong associations between K8 mutations and the development of human colitis have been found. The keratin contribution to colonic health comes from the K8 knock-out (K8-/-) mouse model, which develops an early chronic inflammation and hyperproliferation in the colon. The aim of this thesis was to investigate how keratins contribute to intestinal health and disease mainly by the experimental analysis using the K8-/- mouse colon and cell culture models. The work described here is divided into three studies. The first study revealed involvement of keratins in Notch1 signaling, which is the master regulator of cell fate in the colon. Immunoprecipitation and immunostaining, both in vitro and in vivo showed that K8 binds and co-localizes with Notch1. Interestingly, overexpression of keratins enhanced Notch1 levels and stabilized Notch intracellular domain (NICD), leading to higher activity of Notch signaling. The dramatic decrease in Notch activity in the K8-/- colon resulted in a differentiation shift towards goblet and enteroendocrine cells. The second study focused on the involvement of keratins in colitis-associated cancer (CAC). Although, the K8-/- inflamed colon did not develop colorectal cancer (CRC) spontaneously, it was dramatically more susceptible to induced CRC in two CRC models: azoxymethane (AOM) and multiple intestinal neoplasia (ApcMin/+). To understand how the loss of K8 contributes to CAC, the epithelial inflammasome signaling pathway was analyzed. The released component of active inflammasome, cleaved caspase-1 and its downstream protein, interleukin (IL)-18, were significantly increased in K8-/- and K8-/-ApcMin/+ colons. The inflammasome pathway has recently been suggested to control the levels of IL-22 binding protein (IL-22BP), which is a negative regulator of IL-22 activity. Interestingly, the activated inflammasome correlated with an upregulation of IL-22 and a complete loss of IL-22BP in the K8-null colons. The activation of IL-22 was confirmed by increased levels of downstream signaling, which is phosphorylated signal transducer and activator of transcription 3 (P-STAT3), a transcription factor promoting proliferation and tissue regeneration in the colon. The objective of the third study, was to examine the role of keratins in colon energy metabolism. A proteomic analysis identified mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase 2 (HMGCS2) as the major ownregulated protein in the K8-/- colonocytes. HMGCS2 is the rate-limiting enzyme in ketogenesis, where energy from bacterially produced short chain fatty acids (SCFAs), mainly butyrate, is converted into ketone bodies in colonic epithelium. Lower levels and activity of HMGCS2 in the K8-/- colon resulted in a blunted ketogenesis. The studies upstream from HMGCS2, identified decreased levels of the SCFA-transporter monocarboxylate transporter 1 (MCT1), which led to increased SCFA content in the stool suggesting impaired butyrate transport through the colonic epithelium. Taken together, the results of the herein thesis indicate that keratins are essential regulators of colon homeostasis, in particular epithelial differentiation, tumorigenesis and energy metabolism.
