A phonological and tonal analysis of Samue using Optimality Theory

The topic of the present doctoral dissertation is the analysis of the phonological and tonal structures of a previously largely undescribed language, namely Samue. It is a Gur language belonging to the Niger-Congo language phulym, which is spoken in Burkina Faso. The data were collected during the fieldwork period in a Sama village; the data include 1800 lexical items, thousands of elicited sentences and 30 oral texts. The data were first transcribed phonetically and then the phonological and tonal analyses were conducted. The results show that the phonological system of Samue with the phoneme inventory and phonological processes has the same characteristics as other related Gur languages, although some particularities were found, such as the voicing and lenition of stop consonants in medial positions. Tonal analysis revealed three level tones, which have both lexical and grammatical functions. A particularity of the tonal system is the regressive Mid tone spreading in the verb phrase. The theoretical framework used in the study is Optimality theory. Optimality theory is rarely used in the analysis of an entire language system, and thus an objective was to see whether the theory was applicable to this type of work. Within the tonal analysis especially, some language specific constraints had to be created, although the basic Optimality Theory principle is the universal nature of the constraints. These constraints define the well-formedness of the language structures and they are differently ranked in different languages. This study gives new insights about typological phenomena in Gur languages. It is also a fundamental starting point for the Samue language in relation to the establishment of an orthography. From the theoretical point of view, the study proves that Optimality theory is largely applicable in the analysis of an entire sound system.

Sähköpostista sosiaaliseen mediaan - sosiaalisen median strategia muoviteollisuusalan yritykselle

Sosiaalinen media on muuttanut markkinointia vuorovaikutteisuudella, avoimuudella ja läpinäkyvyydellä. Siksi yritysten kannattaa miettiä kuinka ja miksi lähteä mukaan sosiaaliseen mediaan. Tutkimusta asiasta on rajallisesti ja siksi tässä työssä rakennetaan sosiaalisen media strategia muoviteollisuusalan yritykselle. Työn empiirisessä osuudessa sosiaalisen median strategisia tavoitteita kysyttiin Uponorin johdolta sähköpostikyselyllä. Tulokset analysoitiin kvalitatiivisesti. Lisäksi kartoitettiin Uponorin henkilökunnalle tehdyn verkkopohjaisen lähtötila-analyysin avulla sosiaalisen median käyttöönottoa edistäviä ja estäviä tekijöitä yrityksissä. Aineisto analysoitiin kvantitatiivisin menetelmin. Tulosten perusteella myönteinen suhtautuminen voi edistää sosiaalisen median käyttöönottoa yrityksissä. Toisaalta tutkimuksessa ei voitu osoittaa, että yrityskulttuuriset tekijät estäisivät sosiaalisen median käyttöönottoa. Sosiaalisen median strategia rakennettiin teorian ja kyselyiden tulosten perusteella. Sosiaalisen median käyttö yrityksissä lisääntyy, joten jatkotutkimusta tarvitaan sosiaalisen median hyödyntämisestä yrityskontekstissa myös ulkoisten sidosryhmien osalta.

Creating Value for Corporate Sustainability: Stakeholder Engagement

The thesis aims to build a coherent view and understanding of stakeholder engagement’s contribution to corporate sustainability value creation. Theory suggests that corporate sustainability relies on sustainable relationships between the firm and its multiple stakeholders. This study is qualitative and evidence is derived from integrative analysis of literature, secondary data and case study analysis. The findings from the interviews analysis supplement the framework developed as the results of the literature review. The results obtained throughout the thesis research imply that stakeholder engagement helps develop more thorough understandings of issues and alternative perspectives, which in turn facilitates the decision-making processes improvement. The improvement is also achieved through ethical analysis, by weighing the impact of firm’s decisions on all relevant groups. Therefore, clear communication and exchange of information also improve the acceptance of sustainability initiatives amongst stakeholders both in terms of building trust and managing expectations. As practical implications, this thesis presents organizational practices that can be employed by companies to support effective engagement with stakeholders. The described practices could enhance processes such as partnership and co-creation resulting in greater sustainable development.

Extreme Observables and Optimal Measurements in Quantum Theory

Optimization of quantum measurement processes has a pivotal role in carrying out better, more accurate or less disrupting, measurements and experiments on a quantum system. Especially, convex optimization, i.e., identifying the extreme points of the convex sets and subsets of quantum measuring devices plays an important part in quantum optimization since the typical figures of merit for measuring processes are affine functionals. In this thesis, we discuss results determining the extreme quantum devices and their relevance, e.g., in quantum-compatibility-related questions. Especially, we see that a compatible device pair where one device is extreme can be joined into a single apparatus essentially in a unique way. Moreover, we show that the question whether a pair of quantum observables can be measured jointly can often be formulated in a weaker form when some of the observables involved are extreme. Another major line of research treated in this thesis deals with convex analysis of special restricted quantum device sets, covariance structures or, in particular, generalized imprimitivity systems. Some results on the structure ofcovariant observables and instruments are listed as well as results identifying the extreme points of covariance structures in quantum theory. As a special case study, not published anywhere before, we study the structure of Euclidean-covariant localization observables for spin-0-particles. We also discuss the general form of Weyl-covariant phase-space instruments. Finally, certain optimality measures originating from convex geometry are introduced for quantum devices, namely, boundariness measuring how ‘close’ to the algebraic boundary of the device set a quantum apparatus is and the robustness of incompatibility quantifying the level of incompatibility for a quantum device pair by measuring the highest amount of noise the pair tolerates without becoming compatible. Boundariness is further associated to minimum-error discrimination of quantum devices, and robustness of incompatibility is shown to behave monotonically under certain compatibility-non-decreasing operations. Moreover, the value of robustness of incompatibility is given for a few special device pairs.

Explaining the intention to play and behavior of playing sports betting games of young Finnish adults : an application of the theory of planned behavior

The aim of this Master’s Thesis was to examine the determinants of intention and behavior of playing sports betting games in order to explain the intention to play in a more precise way and to be able to understand the behavior of playing. The theory of planned behavior was applied in explaining the intention of young Finnish adults aged 18 to 34. A quantitative research method was applied and an online survey was sent to the students of Lappeenranta University of Technology and to the subscribers of Urheilulehti in order to reach a sample that present the young population of Finland. The theory of the study focused on the theory of planned behavior and its antecedents, attitude towards behavior, subjective norms, perceived behavioral control as well as motivation. By analyzing the data, causal relationships were found through which the explanation of intention was possible. The results showed that attitude towards playing, subjective norms, perceived behavioral control and motivation impact the formation of intention significantly. The results also indicated that intention impacts significantly to the playing frequency.

Analysis of the Change Management Process in a Multinational Company

The purpose of this thesis was to study change management and find out how the theory applies to practise with the help of studying an organizational change process. The goal was to investigate the different ways of the change management and how those could be utilized in practise. The purpose was also to see what kind of tools and information packages for change management the company involved has developed and taken in to use and check if these could have been utilized in the change process studied in this thesis. This thesis was established by studying the theory of change management and interviewing the people involved in the organizational change and the stakeholders. The questions were formed in line with the change management theory. The main theory used was John P. Kotter’s Eight Steps of Change. The study revealed valuable details about change processes in real life and concrete improvement ideas were recognized from the interviews. Overall the people were quite happy with the outcome of the change process. There were also some failures identified in this change process. Most probably those can be avoided in the future if people planning the change are familiar with the company’s new information packages and tools for change management. Change management is a complex area that is still today quite often forgotten by companies. Effective change management can give a huge competitive advantage for a company. Acknowledging that change process is always complex and not easy is already a good step forward in handling change processes. All changes need change management and understanding the way people react on change. A good and efficient change management is the key to make the change process smooth and easier for the people involved.
