In studying organisational change in Air Seychelles, the context, content and process of change together with the interconnections of the airline and the tourism industry in Seychelles through time is explored. The literature review shows that the substantive issues of interest to this study, contextualism as a theory of methods in management research, requires a case based research in particular with regards to the following gaps in the literature: the integration of inner and outer perspectives on sustaining competitive advantage, and conceptual insights on how strategy links firms and their environment. The study adopted a contextual and processual framework to build a theoretical perspective of competitive advantage. The study contributes to the field of strategic management and tourism development in Seychelles in the following ways: firstly, the development of a contextual and processual framework to explain the transformation of firms over time; secondly, the development of an understanding of the historical context of the tourism industry and its interactions with other sectors of the Seychelles economy; thirdly, developing an understanding of how Air Seychelles developed its resources and capabilities to sustain competitive advantage; fourthly, linking change processes and action to performance and in a sense developing an understanding on strategy implementation of strategic management practice in Air Seychelles. The study sheds some light on strategy formation and implementation at the firm level, and the dynamics between the firm and the industry. The findings suggest that firms respond opportunistically to external discontinuities in a dynamic environment - the entrepreneurial leadership of a firm prepares and support managers to operate under conditions of great uncertainty and ambiguity and allows them to behave opportunistically. / Graduate School of Business Leadership / DBL / Thesis (D.

No. of bitstreams: 1 Jose Carlos Pires de Campos Filho.pdf: 1230163 bytes, checksum: 7aecdf4937e6fc88ebc0a96eb18906df (MD5) Previous issue date: 2012-08-24 / The objective of this dissertation is to expose the philosophical assumptions of the theory of the philosopher St. Augustine on the nature of the ethical and legal State The thought here is understood as a defense of the just State and of the conception of natural law against accusations that Christianity causes injury to the political community. The Augustinian conception of a just and happy society allows, instead, enhancing the civic virtues as a means to achieve the common good and peace. The Augustinian ontology allows the truth to be the reference of virtues and vices, as precepts of action capable of forming the unity of a civilization. The "City of God" is the allegory of a just society that is present in this world through the ages in coexistence with the earthly state / O objetivo desta dissertação é expor os pressupostos filosóficos centrais da teoria do filósofo Santo Agostinho sobre a natureza do Estado ético-jurídico. O pensamento é aqui compreendido como uma defesa do Estado justo e da concepção de lei natural contra as acusações de que o Cristianismo causa prejuízo à comunidade política. A concepção agostiniana de sociedade justa e feliz permite, ao contrário, aprimorar as virtudes cívicas como meio para alcançar o bem comum e a paz. A ontologia agostiniana permite que a verdade seja a referência das virtudes e dos vícios, como preceitos do agir capazes de formar a unidade de uma civilização. A Cidade de Deus é a alegoria de sociedade justa presente no mundo através dos tempos em convivência com o Estado terreno

The Boneh-Boyen signature scheme is a short signature scheme which is provably secure in the standard model under the q-Strong Diffie-Hellman (SDH) assumption. The primary objective of this thesis is to examine the relationship between the Boneh-Boyen signature scheme and SDH. The secondary objective is to survey surrounding topics such as the generic group model, related signature schemes, intractability assumptions, and the relationship to identity-based encryption (IBE) schemes. Along these lines, we analyze the plausibility of the SDH assumption using the generic bilinear group model. We present the security proofs for the Boneh-Boyen signature scheme, with the addition of a small improvement in one of the probability bounds. Our main contribution is to give the reduction in the reverse direction; that is, to show that if the SDH problem can be solved then the Boneh-Boyen signature scheme can be forged. This contribution represents the first known proof of equivalence between the SDH problem and Boneh-Boyen signatures. We also discuss the algorithm of Cheon for solving the SDH problem. We analyze the implications of Cheon's algorithm for the security of the Boneh-Boyen signature scheme, accompanied by a brief discussion on how to counter the attack.

Teisės kreiptis į teismą teisminės gynybos užtikrinimas yra vienas iš pagrindinių teisinės valstybės statusą patvirtinančių siekiamų tikslų. Magistro darbe teisė kreiptis į teismą teisminės gynybos procesine teisine prasme, t. y. teisė pareikšti ieškinį (pareiškimą), analizuojama pasitelkiant lyginamąjį tyrimo metodą, įgalinantį palyginti atskirų valstybių - Lietuvos Respublikos (toliau – Lietuvos) ir Vokietijos Federacinės Respublikos (toliau –Vokietijos) - teisės kreiptis į teismą įgyvendinimo procesinės tvarkos teisinį reguliavimą. Abejose šalyse teisė kreiptis į teismą teisminės gynybos reglamentuojama aukščiausią teisinę galią turinčio teisės akto, t. y. Konstitucijos, normomis. Teisės kreiptis į teismą teisinis reguliavimas, esant asmens teisių pažeidimui privatiniuose teisiniuose santykiuose, Lietuvoje ir Vokietijoje skiriasi: Vokietijos Pagrindinio įstatymo 19 str. 4 d. garantuoja teisę kreiptis į teism���� tik tuo atveju, kai teisių pažeidėjas yra viešoji valdžia. Tačiau Vokietijos Konstitucinis Teismas yra konstatavęs, jog teisiniams ginčams, nepatenkantiems į Pagrindinio įstatymo 19 str. 4 d. ribas, teisė kreiptis į teismą garantuojama įtvirtintu teisinės valstybės principu. Priešingai nei Vokietijoje, Lietuvos Konstitucijoje yra įtvirtinta bendroji teisės norma, taikoma kilusiems ginčams tiek civiliniuose, tiek kitokio pobūdžio teisiniuose santykiuose. Kiekvienas, norintis pasinaudoti teisės aktuose įtvirtinta teise kreiptis į teismą, privalo laikytis...

In dieser Magisterarbeit wird der Justizgewaehrungsanspruch im Sinne des prozessrechtlichen Aspektes, d. h. wie das Recht vor Gericht einzuklagen, analysiert. Die Eroerterung vom Justizgewaehrungsanspruch wird mit Anwendung eines Vergleichsmethodes erledigt. Das Ziel dieser Magisterarbeit ist die Prozessordnung der Verwirklichung vom Justizgewaehrungsanspruch in Litauen und in Deutschland zu vergleichen. In beiden Laendern wird der Justizgewaehrungsanspruch auf der obersten Regelungsebene verankert – im Grundgesetz (GG) der Bundesrepublik Deutschlands und in der Verfassung Litauens. Die Rechtsschutzgarantie in privatrechtlichen Verhaeltnissen ist in verfassungrechtlichen Normen unterschiedlich geregelt: Art. 19 Abs.4 GG schuetzt die Rechte des Menschens nur bei Velretzung durch oeffentliche Gewalt. Das Bundesverfassungsgericht hat den aus dem Rechtsstaatsprinzip in Verbindung mit den Grundrechten folgenden allgemeinen Justizgewährungsanspruch zunächst als Grundlage des Rechtsschutzes in zivilrechtlichen Streitigkeiten anerkannt, für die Art.19 Abs.4 GG nicht anwendbar ist. Im Gegensatz dazu gibt es eine allgemeine verfassungsrechtliche Norm in Verfassung Litauens, die nicht nur fuer die oeffenltich-rechtlichen, sondern auch fuer die zivilrechtlichen Streitigkeiten gilt. Jeder, wer sein Recht vor Gericht einzuklagen realisieren moechte, muss es gemaess... [to full text]

Šio darbo tikslas – kompleksiškai išanalizuoti ir palyginti teisės kreiptis į teismą įgyvendinimo procesinę tvarką pagal Lietuvos ir Austrijos civilinio proceso įstatymus. Abiejose šalyse konstituciniu lygmeniu įtvirtintą teisę kreiptis į teismą detalizuoja civilinio proceso įstatymuose nustatyta šios teisės įgyvendinimo tvarka. Darbe teorinių ir empirinių metodų pagalba yra analizuojama teisė kreiptis į teismą, jos turinys, teisės kreiptis į teismą prielaidos ir sąlygos, nustatytos atsisakymo priimti ieškinį pagrinduose, įtvirtintuose Lietuvos ir Austrijos civilinio proceso įstatymuose. Remiantis moksline literatūra, teisės aktais, Lietuvos Aukščiausiojo Teismo ir Austrijos Aukščiausiojo Teismo (Oberster Gerichtshof) praktika atskiruose baigiamojo darbo skyriuose analizuojami Lietuvos ir Austrijos civilinio proceso kodeksuose numatyti atsisakymo priimti ieškinį pagrindai. Atlikus lyginamąją Lietuvos ir Austrijos civilinio proceso įstatymų analizę, prieinama išvados, kad abiejų valstybių civilinio proceso įstatymuose įtvirtinti atsisakymo priimti ieškinį pagrindai yra beveik identiški, teisė kreiptis į teismą yra tinkamai reglamentuota ir įgyvendinama nepažeidžiant įstatymuose numatytų reikalavimų. Tiek Lietuvoje, tiek Austrijoje įtvirtinti baigtiniai atsisakymo priimti ieškinį pagrindų sąrašai nesudaro kliūčių asmenims pasinaudoti teise kreiptis į teismą. Taip pat darbe pateikiami pasiūlymai Lietuvos įstatymų leidėjui dėl kai kurių civilinio proceso įstatymų nuostatų...

Den Justizgewärungsanspruch, den die Verfassungen der beiden Ländern durchsetzen, detailisiert die Ordnung der Verwirklichung dieses Rechts in den Gesetzen des Zivilprozesses. In der Arbeit analysiert man den Justizgewärungsanspruch, Inhalt des Justizgewährungsanspruchs (die Prozessvoraussetzungen und die Rechtszugvoraussetzungen sind in den Gesetzen des Zivilprozesses verwirklicht, die in den Gründen der Zurückweisung der Klage festgesstelt sind). Hier werden auch die Werke der Rechtswissenshaftler in Litauen und Österreich besprochen. In einzelnen Teilen dieser Arbeit werden die Gründen der Zurückweisung der Klage besprochen. Diese Gründe analysiert man anhand der Gesetze, der Rechtsprechung, der Wissenschaft des Zivilprozessrechtes. Nach der vergleichenden Analyse der Gesetze des Zivilprozesses in Litauen und Österreich kann man die Schlussfolderung ziehen, das die Gründen der Zurückweisung der Klage fast identisch sind. Der Justizgewährungsanspruch ist ausführlich reglementiert und verwirklicht man ohne Verletzungen der Gesetze. Sowohl in Litauen als auch in Österreich ist die Endliste der Gründen der Zurückweisung der Klage verwirklicht, die keine Hindernisse der Personen, die den Justizgewährungsanspruch nutzen wollen, machen. In der Arbeit werden auch die Vorschläge für den Gesetzgeber Litauens wegen... [to full text]

The people in the organisation are the key to quality and effective change and improvement in schools. A new paradigm in school leadership, namely teacher leadership, grounded in distributed leadership theory and supported by enabling policies, provides a platform for school wide capacity building where more and more people recognise the potential of other team members, promote it and thus give stimulus for significant change. The purpose of the research was to determine the perspectives, perceptions and readiness of educators in the Eden and Central Karoo Education District for teacher leadership, as well as educators’ perceptions regarding the school culture required for teacher leadership to be nurtured and sustained. A total number of 283 educators participated in this study, including principals, members of school management teams, veteran, middle, novice educators and district officials. A series of instruments were used to determine educators’ perspectives, perceptions and readiness for teacher leadership, including the Teacher Leadership Readiness Instrument (TLRI) and the Teacher Leadership School Survey (TLSS). Data revealed that educators held positive assumptions about teacher leadership; that educators were collectively ready for teacher leadership; and that they perceived their school cultures as healthy for teacher leadership practices. Educators used language of leadership which can be associated with the organisational and transformational leadership theory; indicated that they experienced barriers to teacher leadership; and that there is a need for professional development in relation to teacher leadership. A significant difference was found between the preliminary leadership and barriers to teacher leadership perceptions held by district officials and other educators (principal, member of school management team, veteran, middle and novice). A significant difference was also found between members of school management teams and other educators (middle and novice) in relation to their readiness for teacher leadership. Significant relationships were found between educators’ preliminary leadership and readiness for teacher leadership perceptions, as well as between their readiness for teacher leadership and their perceptions about a healthy school culture for teacher leadership. These findings have significant implications for leadership practices, collaboration, capacity-building and improvement in schools, educators’ self-esteem, motivation and productivity, as well as student outcomes. / Educational Studies / Thesis (D.
