A digital signature scheme is the process of signing an electronic message that can be transmitted over a computer network. Digital signatures provide message authentication that can be proved to a third party. With the rise of electronic communications over the Internet, digital signatures are becoming increasingly important, especially for the exchange of messages of legal significance. In 1988, Goldwasser, Micali and Rivest (GMR) [31] defined a signature scheme as a collection of algorithms: key generation, signature generation and signature verification. They defined a signature scheme as secure if it was existentially unforgeable against a chosen-message attack. These general definitions suited most signatures at the time, however, over the last decade digital signatures have emerged for which the GMR definitions are unsuitable. These signature schemes, together with their applications and security and efficiency considerations, will be explored in this thesis. These signature scheme variations have been classified by the additional services they provide to ordinary signature schemes, namely increased efficiency, increased security, anonymity, and enhanced signing and verifying capabilities.

Cultural tourism provides opportunities for ethnic minorities to showcase their cultures, customs and heritage. At the same time, it causes a series of tensions and issues of authenticity and commodification have been the subjects of lively debate among tourism researchers. However, little research has been done to date concerning the roles of stakeholders who authenticate cultural resources. This thesis develops a conceptual framework that is employed to enhance understanding of the authenticity of cultural tourism when ethnic Li communities in Hainan Island, China, experience tourism development. Folk villages are used as a significant point of access for investigating the tensions which emerge in authenticating cultural resources. Four key stakeholders are identified: (1) governments; (2) tourism businesses; (3) visitors; and, (4) ethnic communities. Five pairs of yardsticks were developed based upon Swain's (1989) work to examine the issue of authentification. These constructs are: non-commercialization versus commodification, cultural evolution versus museumification, economic development versus cultural preservation, ethnic autonomy versus state regulation, and mass tourism development versus sustainable cultural tourism. The findings suggest that authenticity is relative rather than absolute and, like beauty, is in the eye of the beholder. Therefore, it is necessary to shift from a previous focus on the nature and identification of authenticity to the more tractable question of authentification. The various stakeholders exhibit different positions with respect to the various paradoxes and the tensions that exist between their poles. For example, governments pay more attention on the control of ethnic autonomy whilst tourism businesses prioritize the economic development. Tourists exhibit blurred perceptions of authenticity whilst ethnic minority supports the maintenance of their of culture but gives priority to jobs and remuneration. This thesis demonstrates that it is more useful to evaluate who authenticates and the interests that such claims serve, rather than to adhere to some absolute standard of 'authentic' ethnicity. It makes recommendations for tourism planners, such as ethnic participation in the decision-making process, the development of strategic alliance among tourism stakeholders, and the taking of steps to promote the maintenance of Li culture. It also suggests opportunities for applying this conceptual framework of cultural tourism to other different situations, both within Hainan and elsewhere.

Destination image is a concept created by different demand and supply agents. The balance between what is expected and what is being delivered is essential in promoting the destination. The main goal of this study is to describe the different destination images related to Dracula tourism in Transylvania. This is accomplished by looking at the Western tourists’ expectations and demands as expressed in their travel blogs, and by analyzing the supply side through the elicitation of information from locals and Bran Castle tour guides through qualitative interviews. Qualitative content analysis was used to analyze the content, visual and audio information on sampled blogs and interviews. This method identified 11 different themes which captured the overall destination image. The themes focused primarily on historical and fictional images of the destination, on the type of tourists visiting Bran Castle, but also on the locals’ image and response to Dracula tourism. The findings of this study reveal that the majority of Western bloggers visit Bran in search for Count Dracula; however, the Bran Castle tour guides focus on presenting the historical truth. Local residents, although seeing Dracula as a national hero, sometimes adopt the mythical image as a marketing or product development tactic in selling to visitors. Nevertheless, the stakeholders involved in the creation of the image each fit into different destination image frameworks, allowing for the creation of an overall destination image based on historical and fictional elements.

In light of claims that liberalism has led to a breakdown in society, this paper refutes these claims by examining how workplace spirituality at Starbucks Coffee impacts the identities of several employees. While others have examined workplace spirituality as a management technique, this study illustrates how it could be understood as a distinctly modern way of being religious. By linking the ethnography to recent religious trends, this study illustrates how employees are cultivating a spirituality of an inner self. Specifically, these employees accomplish three things. First, they claim to discover their true authentic self. Also, despite the alienation of modern life, workplace spirituality helps employees establish new forms of community. Third, they rework traditional notions of authority in the workplace in ways that strengthen a connection with their inner selves. Finally, the author briefly explores the broader ethical and religious implications that arise from understanding the dynamics of workplace spirituality.

This project works to illuminate some of the main theoretical claims that writers of the third wave make in order to understand these claims as rhetorical devices used to make themselves visible and real. Being visible is a common theme in third wave texts and realness is a site that is both contested and embraced. Being Visible and being real work together to situate third wave actors in a U.S. feminist continuum that is sprinkled with contradiction and ambiguity. This thesis will examine the contextual development of third wave feminism, and then using examples of realness and visibility in the three third wave anthologies, Being Real, Third Wave Agenda, and Catching a Wave, this thesis will interrogate at the rhetorical significance of those themes.

Perception of today’s business is characterized through movements on globalization, transnational companies and global networks across the whole world. The perspective of a leader in the field of acting has moved from a national to a multinational level. Also the abilities and skills which are needed to develop further in order to succeed in this global transformation have changed. This thesis project, entitled ‘What needs a leader?, will touch upon these prospective abilities and skills. In the growing global economy the abilities as a prospective leader must continually develop. It seems to us that leading and not managing people is the first approach in direction of efficient leadership. Lead- ership and Management cannot be compared; one is about people, and the other one is about facts. Thus, in our thesis we take this as a challenge to develop the component of leadership further and want to explore which specific skills are needed. Communication and emotional intelligence are two fields of knowledge, which have received a great deal of focus in this research field high. Thus, only a few researches have concentrated their research on both fields of knowledge as a powerful leadership tool. Our thesis discusses the relevance of communication aligned with emotional intelligence as an efficient leadership tool in today's global networked society.

Denna studie diskuterar hur kulturarv, i detta fall Friluftsmuseet Gamla Linköping, är uppbyggt och hur dess utformning gör att anspråk på historisk representation och autenticitet. De tre män som deltog som informanter i denna studie vet att Gamla Linköping är konstruerad genom omlokalisering av gamla byggnader till platsen, vilket skapar bilden av en liten stad i början av 1900-talet. Under intervjuerna med informanterna, frågade jag om de upplever Gamla Linköping som antingen ett museum eller en stadsdel - och svaret var komplex. I huvudsak ansåg informanterna att Gamla Linköping är ett levande samhälle som illustrerar det förflutna. Jag har genomfört denna studie genom semistrukturerade intervjuer och deltagande observationer på Adventsmarknaden i Gamla Linköping. Genom de deltagande observationerna på Adventsmarknaden blev det möjligt för informanterna att fortsätta reflektionen över vad och hur de uppfattar vara representativ och autentiskt i förhållande till Gamla Linköping miljön. Studien är indelad i fyra delar; Museum eller stadsdel?, Dåtiden i nutiden, Adventsmarknaden, Kulturarv - för vem?. I denna studie har jag diskuterat det faktum att alla kulturarv produceras av olika samtida maktcentra. Det innebär att kulturarv inte är något naturgivet objekt som i sig själv har ett värde – utan genom samtidens normer tillägnas vissa historiska kulturella uttryck värden och konstruerar subjektiva kulturarv. / This study has discussed how cultural heritage, in this case the museum Old Linköping, is constructed and how its design makes claim to historical representation and authenticity. The three men who participated as informants in this study know that Old Linköping is constructed through the relocation of old buildings to the site, thus creating the image of a small town in the early 1900's. During the interviews with informants, I asked the question if they experience Old Linköping as either a museum or a district - and the answer was complex. In essence, the informants generally held view that Old Linköping will be a living community that illustrates the past. I have conducted this study through semi-structured interviews and participant observations on the Advent market in Old Linköping. Through participant observation in the Advent market, it became possible for the informants to continue to reflect on what and how they perceive to be representative and authentic in relation to the Old Linköping environment. The study is divided into four parts; Museum or district?, Past in the present, Advent Market, Heritage - for whom?. In this study, I have discussed the fact that all cultural heritages are produced by various contemporary centers of power. This means that cultural heritage is not something given by nature but by current standards are directed toward certain historical cultural expressions of values and constructs a subjective cultural heritage.
