Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening. Teleoperator (TO) systems place people at a remote physical destination embodied as a robotic device, and where typically participants have the sensation of being at the destination, with the ability to interact with entities there. In this paper, we show how to combine IVR and TO to allow a new class of application. The participant in the IVR is represented in the destination by a physical robot (TO) and simultaneously the remote place and entities within it are represented to the participant in the IVR. Hence, the IVR participant has a normal virtual reality experience, but where his or her actions and behaviour control the remote robot and can therefore have physical consequences. Here, we show how such a system can be deployed to allow a human and a rat to operate together, but the human interacting with the rat on a human scale, and the rat interacting with the human on the rat scale. The human is represented in a rat arena by a small robot that is slaved to the human"s movements, whereas the tracked rat is represented to the human in the virtual reality by a humanoid avatar. We describe the system and also a study that was designed to test whether humans can successfully play a game with the rat. The results show that the system functioned well and that the humans were able to interact with the rat to fulfil the tasks of the game. This system opens up the possibility of new applications in the life sciences involving participant observation of and interaction with animals but at human scale.

While the supply of water to dry or arid mountain regions has long been a major challenge, the on-going processes of climatic and socio-economic change currently affecting the hydrosystems of the Alps raise the spectre of renewed pressure on water resources and possible local shortages. In such a context, questions relating to fair distribution of water are all the more sensitive given the tendency to neglect the social dimension of sustainability. The present paper makes both a conceptual and empirical contribution to this debate by analysing a system of distribution that has a long experience of water scarcity management: the community governance models traditionally linked to the irrigation channels, or bisses, typical of the Swiss Alpine canton of Valais. More specifically, we evaluate these models in terms of accessibility and equity, characteristics that we use to operationalize the notion of 'fair distribution'. We examine these dimensions in three case studies with a view to highlighting the limitations of the aforementioned models. Indeed, despite their cooperative and endogenous nature, they tend to not only exclude certain members of the population, but also to reproduce rather than reduce social inequalities within the community. In general, these results challenge the rosy picture generally found in the literature relating to these community governance models.

The main concept of this paper is managing brand equity over time. In the theoretical section, a necessary basis for managing brand equity is first built by reviewing the most important themes related to branding. After this the concept of brand equity is discussed thoroughly, and a framework is built for managing brand equity over time. The empirical section illustrates how the case company, Masku, has built its brand equity over the history of the company. What can be derived from this research is that the process of managing brand equity over time can be an implicit process, and means of reinforcing the brand are often used without specific emphasis to generate business.

This thesis investigates performance persistence among the equity funds investing in Russia during 2003-2007. Fund performance is measured using several methods including the Jensen alpha, the Fama-French 3- factor alpha, the Sharpe ratio and two of its variations. Moreover, we apply the Bayesian shrinkage estimation in performance measurement and evaluate its usefulness compared with the OLS 3-factor alphas. The pattern of performance persistence is analyzed using the Spearman rank correlation test, cross-sectional regression analysis and stacked return time series. Empirical results indicate that the Bayesian shrinkage estimates may provide better and more accurate estimates of fund performance compared with the OLS 3-factor alphas. Secondly, based on the results it seems that the degree of performance persistence is strongly related to length of the observation period. For the full sample period the results show strong signs of performance reversal whereas for the subperiod analysis the results indicate performance persistence during the most recent years.

Traditionally, school efficiency has been measured as a function of educational production. In the last two decades, however, studies in the economics of education have indicated that more is required to improve school efficiency: researchers must explore how significant changes in school organization affect the performance of at-risk students. In this paper we introduce Henry Levin’s adoption of the X-efficiency approach to education and we describe the efficient and cost-effective characteristics of one Learning Communities Project School that significantly improved its student outcomes and enrollment numbersand reduced its absenteeism rate to zero. The organizational change that facilitatedthese improvements defined specific issues to address. Students’ school success became the focus of the school project, which also offered specific incentives, selected teachers, involved parents and community members in decisions, and used the most efficient technologies and methods. This case analysis reveals new two elements—family training and community involvement—that were not explicit parts of Levin’s adaptation. The case of the Antonio Machado Public School should attract the attention of both social scientists and policy makers

One of the most important milestones in the development of theory of mind is the understanding of false beliefs. This study compares children’s understanding of representational change and others’ false beliefs and evaluates the effectiveness of an appearance-reality training for improving children’s false belief understanding. A total of 78 children ranging in age from 41 to 47 months were trained in three sessions and evaluated in a pretest and in a posttest. The results show that for children it is easier to understand representational change than false beliefs in others, and that the improvement after training was greater when starting from a higher score in the pretest. The implications of this for training in false belief understanding are discussed

The aim of this paper is to analyze the effect of price and advertising on brand equity. The dimensionality of brand equity is thoroughly examined, and the effect price, price deals, perceived advertising spending and advertising appeal have on the dimensions of brand equity are analyzed using multiple regression analysis as well as other supporting analyses. Price and advertising are found to be of great importance to brand equity. Arguably the most influential finding is the strong positive effect low prices – an integral brand element – have on the case company brand equity, even though a negative effect was hypothesized based on prior research. The results also support separating advertising appeal from perceived advertising spending, as well as linking service quality as part of the overall perceived quality in the context of service-intensive firms.

The study of convergence and divergence in global economy and social development utilises comparative indicators to investigate the contents of economic and social development policy and their effects on the global samples that represent the rich industrial, semi-industrial and the poor developing nations. The study searchesfor answers to questions such as "what are the objectives of economic growth policies in globalisation under the imperatives of convergence and divergence, and how do these affect human well-being in consideration to the objectives of social policy in various nations?" The empirical verification of data utilises the concepts of the `logic of industrialism´ for comparative analysis that focuses mainly on identifying the levels of well-being in world nations after the Second World War. The perspectives of convergence and divergence in global economy and social development critically examine the stages of early development processes in global economy, distinguish the differences between economy and social development, illustrate the contents of economic and social development policies, their effects on rich and poor countries, and the nature of convergence and divergence in propelling economic growth and unequal social development in world nations. The measurement of convergence and divergence in global economy and social development utilised both economic and social data that were combined into an index that measures the precise levels of the effects of economic and social development policies on human well-being in the rich and poor nations. The task of finding policy solutions to resolve the controversies are reviewed through empirical investigations and the analyses of trends indicated within economic and social indicators and data. These revealed how the adoption of social policy measures in translating the gains from economic growth, towards promoting education, public health, and equity, generate social progress and longer life expectancy, higher economic growth, and sustain more stable macro economy for the nations. Social policy is concerned with the translation of benefits from objectives of global economic growth policies, to objectives of social development policy in nation states. Social policy, therefore, represents an open door whereby benefits of economic growth policies are linked with the broader objectives of social development policy, thereby enhancing the possibility of extending benefits from economic growth to all human being in every nation.

Bisnesenkelit, eli yksityiset riskisijoittajat ovat tärkeä ulkopuolinen rahoittajataho aloittaville kasvuyrityksille. Varallisuuden sijoittamisen ohella bisnesenkeleiden tärkeä ominaisuus on osaamisen ja verkostojen sijoittaminen yritykseen, minkä myötä yritys saa paremmat edellytykset kasvua varten. Bisnesenkeleiden kontribuutio ajoittuu tyypillisesti jälki-investointivaiheeseen, eli varallisuuden sijoittamisen jälkeen. Osallistumi-sen myötä yrittäjä-sijoittajasuhde on tärkeä taustatekijä bisnesenkelin kontribuutiossa aloittavalle kasvuyritykselle. Tutkimuksen tavoitteena oli luoda ymmärrystä bisnesenkelien kontribuutioon aloittavien kasvuyritysten jälki-investointivaiheessa. Tähän päätutkimusongelmaan vastattiin kuvailemalla lähtökohtia bisnesenkelin osallistumiselle, selvittämällä bisnesenkelin konkreettisia osallistumistapoja sekä kontribuutiosta koettua hyötyä erityisesti yrittäjien kannalta. Tutkimus toteutettiin laadullisena tutkimuksena hyödyntäen tapaustutkimusta. Tutkimusaineistona käytettiin neljälle yrittäjälle ja neljälle bisnesenkelille tehtyä teemahaastattelua. Tutkitut yritykset valittiin pääasiassa teknologiatoimialalta. Bisnesenkeleiden osallistumisen taustalla on pyrkimys viedä yritystä eteenpäin kasvua ja tulevasta exitistä saatavaa tuottoa ajatellen. Nämä tavoitteet ohjaavat bisnesenkeliä välittämään yritykseen strategista ja operatiivista osaamistaan sekä verkostojaan yrityksen tarpeista riippuen. Yrittäjän kannalta oleelliseksi havaittiin myös keskustelukumppanin merkitys. Suhteen toimivuuden edellytyksinä ovat erityisesti osapuolten välinen luottamus ja riittävä vuorovaikutus. Bisnesenkelin kontribuutio koettiin pääosin hyödyllisenä, esimerkiksi kasvua nopeuttaen.

This thesis examines the existence and nature of momentum effect in European equity indices. A set of predefined indicators is used to compose momentum portfolios and different holding periods are used to test the strategies over variable time periods as well as under different economical conditions. The data consists of daily closing prices of STOXX Europe 600 index and its 18 super sector indices. Over the study period we follow the performances of a long position in the Winner portfolio, a position in the market neutral zero-cost portfolio and also a position in the risk-controlled zero-cost portfolio. The investment ratio of the risk-controlled zero-cost portfolio is negatively correlated with the realized market volatility. The results show that momentum effect is present in European industries and is most prominent in the short-term. Indicators that are based on short-term performance tend predict the over- and underperformers for the 1-month holding period more reliably than any other indicator/holding period combination. The examination of the strategies under different economical conditions shows that the market neutral approach can create significant returns in times of recession but in times of economic boom the long position in Winner portfolio outperforms the market neutral portfolio by an extensive margin.

The intellectual property (IP) environment in China is still very immature. There are several problems in legal, political, economic, social-cultural, competitive and labor environment which have hindered IP legal enforcement. Under such circumstances, IP misappropriation is a major concern especially for foreign small and medium-sized enterprises (SMEs) doing business in China. These circumstances require foreign companies, no matter whether they are multinational corporations (MNCs) or SMEs and have own manufacturing in China or not, to take strong IP actions. Therefore, the purpose of this study is to discuss how IP can be protected in China in the case of outsourcing and in the case of own manufacturing. The comparison will consider the process of outsourcing and own manufacturing consisting two stages: preparation stage and operation stage. In order to clarify the conceptual arguments, two illustrative case studies were studied. The case data bases on two semi-structured interviews of the managing directors, field notes and archival data. The findings propose that attention in IP protection should be given to following issues: integrating IP strategy into the company’s business strategy, protecting the most critical knowledge, regarding IP steps as a whole in the protection mechanism and making IP strategy as proactive as possible. The major difference between outsourcing and own manufacturing in IP protection is in the operation stage. Besides, the findings also provide managerial advice on IP protection, e.g. foreign managers should be prepared for IP risks in China, they should establish an own IP protection mechanism which matches the company’s situation and they should consider IP protection as an on-going process.
