A Communication Middleware Quality Enhancement with Qt Framework

In this thesis, a Peer-to-Peer communication middleware for mobile environment is developed using the Qt framework and the Qt Mobility extension. The Peer-to-Peer middleware – called as PeerHood – is for service sharing in network neighborhood. In addition, the PeerHood enables service connectivity and device monitoring functionalities. The concept of the PeerHood is already available in native C++ implementation on Linux platform using services from the platform. In this work, the PeerHood concept is remade to be based on use of the Qt framework. The objective of the new solution is to increase PeerHood quality with using functionalities from the Qt framework and the Qt Mobility extension. Furthermore, by using the Qt framework, the PeerHood middleware can be implemented to be portable cross-platform middleware. The quality of the new PeerHood implementation is evaluated with defined quality factors and compared with the existing PeerHood. Reliability, CPU usage, memory usage and static code analysis metrics are used in evaluation. The new PeerHood is shown to be more reliable and flexible that the existing one.

Carbon footprint as part of a company’s external environmental communication

The aim of this thesis was to find out how the carbon footprint calculations can be utilized in the company’s external environmental communication, what is the demand for carbon footprint from the market, and how the other actors in the forest industry have approached the issue. The aim was to recognize the best practises to communicate carbon footprints and to find possibilities to extend the UPM-Kymmene Wood Oy’s mill specific carbon footprints. This research included a literature review, an inquiry to the UPM-Kymmene Wood Oy’s sales offices, and Internet survey concerning the external environmental communication in the forest industry and three small case studies based on mill specific parameters. The inquiry to the sales offices showed that the carbon footprint is not yet a common demand from the customers in the wood product sector. In addition, the Internet survey showed that generally in the forest industry, not much has been done concerning carbon footprint communication so far. The biggest challenge in carbon footprint communication is the variation in the knowledge level of the receivers. In addition btob and btoc communication situations demand a different approach to the issue. Carbon profile brochures developed in the company can be seen as suitable for btob communication situations. Case studies have shown that the contribution of final product transport to the overall carbon footprint was significant. It was recommended to include post mill transport in the carbon footprint information supplied to the btob customers. When discussing environmental communication on a general level it can be stated that a good external environmental communication is based on facts, is open and proactive and takes into account the needs of the receiver. However, the openness and the quality of external environmental communication are essentially strategic decisions. The significance of internal communication as well as the knowhow in the communication and marketing networks play a major role in achieving success in external environmental communication. Carbon footprints are only one part of good balanced external environmental communication. One specific environmental feature like carbon footprint should not be over emphasized to the detriment of other important environmental aspects.

Modeling and Analysis of Noise and Interconnects for On-Chip Communication Link Design

This thesis considers modeling and analysis of noise and interconnects in onchip communication. Besides transistor count and speed, the capabilities of a modern design are often limited by on-chip communication links. These links typically consist of multiple interconnects that run parallel to each other for long distances between functional or memory blocks. Due to the scaling of technology, the interconnects have considerable electrical parasitics that affect their performance, power dissipation and signal integrity. Furthermore, because of electromagnetic coupling, the interconnects in the link need to be considered as an interacting group instead of as isolated signal paths. There is a need for accurate and computationally effective models in the early stages of the chip design process to assess or optimize issues affecting these interconnects. For this purpose, a set of analytical models is developed for on-chip data links in this thesis. First, a model is proposed for modeling crosstalk and intersymbol interference. The model takes into account the effects of inductance, initial states and bit sequences. Intersymbol interference is shown to affect crosstalk voltage and propagation delay depending on bus throughput and the amount of inductance. Next, a model is proposed for the switching current of a coupled bus. The model is combined with an existing model to evaluate power supply noise. The model is then applied to reduce both functional crosstalk and power supply noise caused by a bus as a trade-off with time. The proposed reduction method is shown to be effective in reducing long-range crosstalk noise. The effects of process variation on encoded signaling are then modeled. In encoded signaling, the input signals to a bus are encoded using additional signaling circuitry. The proposed model includes variation in both the signaling circuitry and in the wires to calculate the total delay variation of a bus. The model is applied to study level-encoded dual-rail and 1-of-4 signaling. In addition to regular voltage-mode and encoded voltage-mode signaling, current-mode signaling is a promising technique for global communication. A model for energy dissipation in RLC current-mode signaling is proposed in the thesis. The energy is derived separately for the driver, wire and receiver termination.

Relations between communication and development of family farmers

This research investigates relations between communication and the development of family farmers from the Pontal do Paranapanema region (state of São Paulo), mainly in the municipality of Teodoro Sampaio. Family agriculture in this municipality is represented basically by beneficiaries the Agrarian Reform program. The main hypothesis is that communication contributes positively to the development of those family farmers. Thus, this study aimed to understand communication practices of these farmers and relate them with the development of their families. Quantitative and qualitative research methods were used. Development proxy is understood as the combination between the family living conditions and production. Among the main results, it was found that the effect of communication for "life and production conditions" increases as farmers at superior levels of "development" are analyzed; thus the main hypothesis should not be rejected for those farmers with higher development condition. For the others, communication did not have the same effect because many settled families are not focused on agricultural activities. The main suggestion is to improve ways for producers and professionals from public services related to them to access information.

Corporate Social Responsibility in the Oil and Gas Industry: Environmental Management Systems as a Source of Sustainable Development

The environmental aspect of corporate social responsibility (CSR) expressed through the process of the EMS implementation in the oil and gas companies is identified as the main subject of this research. In the theoretical part, the basic attention is paid to justification of a link between CSR and environmental management. The achievement of sustainable competitive advantage as a result of environmental capital growth and inclusion of the socially responsible activities in the corporate strategy is another issue that is of special significance here. Besides, two basic forms of environmental management systems (environmental decision support systems and environmental information management systems) are explored and their role in effective stakeholder interaction is tackled. The most crucial benefits of EMS are also analyzed to underline its importance as a source of sustainable development. Further research is based on the survey of 51 sampled oil and gas companies (both publicly owned and state owned ones) originated from different countries all over the world and providing reports on sustainability issues in the open access. To analyze their approach to sustainable development, a specifically designed evaluation matrix with 37 indicators developed in accordance with the General Reporting Initiative (GRI) guidelines for non-financial reporting was prepared. Additionally, the quality of environmental information disclosure was measured on the basis of a quality – quantity matrix. According to results of research, oil and gas companies prefer implementing reactive measures to the costly and knowledge-intensive proactive techniques for elimination of the negative environmental impacts. Besides, it was identified that the environmental performance disclosure is mostly rather limited, so that the quality of non-financial reporting can be judged as quite insufficient. In spite of the fact that most of the oil and gas companies in the sample claim the EMS to be embedded currently in their structure, they often do not provide any details for the process of their implementation. As a potential for the further development of EMS, author mentions possible integration of their different forms in a single entity, extension of existing structure on the basis of consolidation of the structural and strategic precautions as well as development of a unified certification standard instead of several ones that exist today in order to enhance control on the EMS implementation.

Corporate responsibility guaranteed by dialogue? Examining the relationship between nongovernmental organizations and business

The main objective of this doctoral dissertation is to examine the relationship between non-governmental organizations and business in the context of academic discourse, corporate responsibility discourse, and stakeholder dialogue. More specifically, motivated by the increasing emphasis on stakeholder dialogue as a tool for corporate responsibility and accountability, the aim is to critically assess the role of stakeholder dialogue as a self-regulatory mechanism, in particular from the perspective of foreign direct investments. The study comprises two parts; an introductory essay containing the research objectives, theoretical foundations and methodological choices, and four research articles that address one sub-objective: 1) to review the literature on NGO-business relations in business and society, management, and international business journals from 1998–2007; 2) to critically analyze the academic discourse on NGO-business relations; 3) to analyze the problematic aspects of sustainable foreign direct investments as a conceptual construct; and 4) to analyze the problematic aspects of stakeholder dialogue in connection with a foreign direct investment. The ontological and epistemological foundations of this dissertation build on the social constructionist view of reality. The dialogue in this study is viewed as a legitimacy bargaining process that is actively shaped by societal parties in discourse. Similarly, articulations of ‘partnership’ and ‘adversarial’ in NGO-business relations in academic business and society discourse are viewed as competing hegemonic interventions in the field. More specifically, the methods applied in the articles are literature review (Article 1), discourse theory (Article 2), conceptual analysis (Article 3), and case study with document analysis (Article 4). This dissertation has three main arguments and contributions. First, it is argued that the potential of stakeholder dialogue as a tool for corporate responsibility and accountability is inherently limited in both contexts. Second, the study shows the power implications of privileging partnership oriented NGO-business relations over adversarial ones, and of placing business at the centre of governance discourse. The third contribution is methodological: a new way to analyze academic discourse is presented by focusing on the problem setting of an article.

Earnings management in the process of preparing corporate financial reports

Earnings management (EM) literature examines managers’ use of judgment in financial reporting and in structuring transactions to alter financial reports for a specific reason. Mainstream EM literature strongly concentrates on statistical research methodologies and it is driven by positive accounting theory. Although EM occurs in the process of preparing corporate financial reports, that process has so far largely remained a “black box” in prior literature. The purpose of this study is to analyze what EM is, how and why it unfolds and how it is intertwined in the process of preparing corporate financial reports. In order to meet the needs of the study, a qualitative case study method will be used. The contribution of this study is threefold. First, it indicates that the concept of EM is not as unam-biguous as the prior literature has assumed. I find that EM is socially constructed and more open to interpretation than absolutely dichotomous conception given by previous studies. Second, this study contributes to our knowledge of the role and the importance of actors involved in conducting EM, indicating that EM is much more actor-dependent than the prior literature has assumed. Third, this study broadens our knowledge base with regard to the processes and potential for EM in academic research.

SOCIAL MEDIA IN INTERNATIONAL BRAND COMMUNICATION OF SMES - A multiple case study of small Finnish design-intensive companies

Social media is a rather new phenomenon which has revolutionised the world of online communication. However, academic research on how companies can benefit from social media is lacking. The research objective of this thesis was to examine the use of social media in international brand communication of small Finnish design-intensive companies. Therefore, this research contributes also to the research gap in SME branding. The focus was on communication targeted at consumers. The research was carried out as a mixed methods research employing the questionnaire and multiple case study methods. The questionnaire was used to gather preliminary information on Finnish design-intensive companies and to provide an eligible list of companies for deeper examination. Then, four case companies were studied in more depth. The empirical evidence of the case companies was mainly gathered through theme interviews. The results of the questionnaire shed light on the internationalisation of small Finnish designintensive companies. On average, the companies had internationalised rather quickly after they had been founded. However, the share of exports was rather low in most of the companies. The results revealed also that social media was already used widely in the exporting companies and the use can be expected to grow in future. The findings of the multiple case study suggest that branding activities in small Finnish designintensive companies are constrained by limited resources and skills. In addition, the branding activities are strongly guided by the vision and values of the entrepreneur(s) rather than extensive marketing research. The brand structure was simple in all case companies and they aimed at having a standardised brand image across markets. However, all case companies had faced a need for some adaptation of their international brand communication. Internationally important brand communication channels were international fairs, the internet, word-of-mouth and social media. Social media offered a cost-effective brand communication channel for the case companies. It was used for various purposes, such as creating brand awareness and affecting how the brand is perceived. The entrepreneurs found the use of social media to be rather easy and the case companies had not faced any major challenges. However, the companies had recognised that communication in social media requires consistency and planning. The planning was rather informal and stayed on a general level. Overall, the utilisation of social media in the case companies was limited by a lack of resources. It seemed to affect especially the follow-up of brand communication in social media which stayed rather superficial.

Pankin reaalioptiot kriisiytyneiden asiakasyrityksien riskienhallinnallisessa lisäluototuksessa

Tämän tutkielman tarkoituksena on ollut tutkia pankin mahdollisuuksia soveltaa reaalioptioajattelua kriisiyrityksien käyttöpääomaan liittyvissä lisäluototusprosesseissa. Kohdepankin rahoitusasiantuntijoita haastattelemalla ja esimerkkitapauksiin tutustumalla tutkia on tutkittu pk-yritysten lisäluototusprosessia ja reaalioptioteorian soveltuvuutta luottoriskinhallintaan. Tutkimuksessa saatiin selville, että pankin luottoprosessin päätöksentekologiikassa on selkeitä yhteneväisyyksiä reaalioptioajattelun kanssa, mutta tietoisesti pankin asiantuntijat eivät sovella reaalioptioteoriaa toimintaansa. Tutkimuksessa havaittiin myös, että tiedostamattoman reaalioptioajattelun hyödyntämisaktiivisuus lisääntyy pankissa sitä mukaa, kun asiakaskohtainen riski kasvaa. Lisäksi kohdepankin asiantuntijat suhtautuivat luottoprosessissa kriisiyrityksille myönnettyihin lisäluottoihin suojautumisoption kaltaisen ajattelumallin tavoin. Toisin sanoen lisäluotto katsottiin asiakasyrityksen toiminnan jatkumisen mahdollistavana tekijänä, jonka avulla pitkän tähtäimen luottoriskin laskeminen on todennäköistä. Reaalioptioteorian tietoinen hyödyntäminen saattaisi tarjota lisätyökaluja asiakasyrityksien skenaarioiden arviointiin ja tukea sitä kautta luottopäätöksen tekemistä ja riskienhallintaa. Reaalioptiot voisivat tuoda joustavuutta ja lisäarvoa sellaisiin tilanteisiin, joissa asiakasyrityksen osalta ei ole olemassa laajaa historiatietoa tai asiakastuntemusta. Reaalioptioiden mahdollistaman joustavuuden sovittaminen säädösten mukaisiin proseduureihin saattaisi olla merkittävä keino pankin prosessin kehittämiseksi ja sisäisen viestinnän tehostamiseksi.

THE IMPACT OF GUANXI TO MULTINATIONAL COMPANIES BUSINESS PERFORMACE, CORPORATE REPUTATION, NEGOTIATIONS AND MANAGEMENT IN CHINA

The modern business development of China began during 1978 and during the last decades Chinese have created one of the most dynamic and strongest economies in the world. China is now second largest trading power calculated in dollars. The special characteristic of this economic development is that it is not copy of any existing economy, instead the developments have been strongly influenced by the Chinese cultural characteristics. One cultural characteristic, guanxi, which is a “network of services and counter- services” is argued to be major component of successful business in China where these changes of services happen between people but also between companies. Obtaining introductions and the guanxi when doing business in China will give attentive audience and security for companies business. Despite the evidenced importance of guanxi, China´s business environment is rapidly changing towards Western economies, which might then reduce the importance of guanxi. Therefore the current impact of guanxi is a important topic to study. The main purpose of this study is to explore the impact of guanxi for Western big and small sized multinational companies´ business processes when doing business in China. This study looks What is the impact of guanxi in contemporary Chinese business environment for foreign companies doing business in China. Sub-questions in this research focus on what is the impact of guanxi on corporate reputation, management and negotiations. Findings present a mixed view where the importance of guanxi is not anymore critical, especially among younger people in the cities, however guanxi was clearly important outside the cities and when dealing with government officials. Efficient use of guanxi can be extremely profitable especially during early stages of business operations and guanxi plays role when bargaining prices and ensuring product quality from the factories. Therefore guanxi should be considered as essential element for successful business in China.
