The Impact of Celebrity Fan Club Towards the Willingness to Stay at Hotel XYZ

Tourism industry is one of the most important industry in Indonesia. In Jakarta, five-star hotel has been one of the most promising business. This research is done to know the impact of Celebrity Fan Club campaign towards the willingness to stay at Hotel XYZ. The four source models, which are source credibility model, source attractiveness model, product match-up model and meaning transferability model, are elements that are used to measure the campaign which will impact the willingness to stay. The sample that the author use is anyone who has experienced staying in five-star hotels. There are 76 samples that was gathered in this research using simple random sampling method. The analysis technique that is used in this research is multiple linear regression to know the relationship between the Celebrity Fan Club which is a celebrity endorsement towards the willingness to stay. The research result shows that Celebrity Fan Club significantly impact the willingness to stay

Unveiling a crystalline topological insulator in a Weyl semimetal with time-reversal symmetry

We consider a natural generalization of the lattice model for a periodic array of two layers, A and B, of spinless electrons proposed by Fu [Phys. Rev. Lett. 106, 106802 (2011)] as a prototype for a crystalline insulator. This model has time-reversal symmetry and broken inversion symmetry. We show that when the intralayer next-nearest-neighbor hoppings ta2, a = A, B vanish, this model supports a Weyl semimetal phase for a wide range of the remaining model parameters. When the effect of ta2 is considered, topological crystalline insulating phases take place within the Weyl semimetal one. By mapping to an effective Weyl Hamiltonian we derive some analytical results for the phase diagram as well as for the structure of the nodes in the spectrum of the Weyl semimetal.Comment: 8 pages, 8 figure

Terrorismo no mar de um mundo globalizado

Tomando o sequestro de turistas em Sipadan, o assalto ao Achille Lauro e o ataque ao Limburg como ponto de partida, este artigo estuda brevemente a definição de pirataria, o princípio da jurisdição universal e a necessidade de apoio, por parte de países estrangeiros, aos Estados que não dispõem de recursos para lutar contra a pirataria, na Convenção das Nações Unidas sobre o Direito do Mar. Avançando para a Convenção para a Supressão de Actos Ilícitos contra a Segurança da Navegação Marítima, e para o Protocolo de 2005 à mesma, o artigo discute formas de minimizar o perigo de acções terroristas no mar, bem como soluções para quando a prevenção não for suficiente para deter os terroristas
