TYPES OF STRATEGIES FOR THE TOURISTIC FIRMS

to develop new ideas, products, services and destinations. For example, there is aninternational interest in developing niches, which are specific interests and activities thatpeople might find interesting as an activity for their holiday. Recent developments thatcharacterize this include the rise of natural-based ecotourism products, of wine and food-based tourism, following on people’s interests, provides an example of a successfuldevelopment of niche products. With all these roles, researchers as well as governmentshave agreed on the need of development strategies, as a successful and beneficial waytowards the future.strategy, corporate strategy, business strategy, developing strategies, tourismoperators

Evolving groups

The class of evolving groups is defined and investigated, as well as their connections to examples in the field of Galois cohomology. Evolving groups are proved to be Sylow Tower groups in a rather strong sense. In addition, evolving groups are characterized as semidirect products of two nilpotent groups of coprime orders where the action of one on the other is via automorphisms that map each subgroup to a conjugate.Comment: This paper collects the results from my master thesis, which I wrote at Leiden University under the supervision of Prof. Hendrik Lenstr

Weighted Evolving Networks

Many biological, ecological and economic systems are best described by weighted networks, as the nodes interact with each other with varying strength. However, most network models studied so far are binary, the link strength being either 0 or 1. In this paper we introduce and investigate the scaling properties of a class of models which assign weights to the links as the network evolves. The combined numerical and analytical approach indicates that asymptotically the total weight distribution converges to the scaling behavior of the connectivity distribution, but this convergence is hampered by strong logarithmic corrections.Comment: 5 pages, 3 figure

Evolving wormhole geometries

We present here analytical solutions of General Relativity that describe evolving wormholes with a non-constant redshift function. We show that the matter that threads these wormholes is not necessarily exotic. Finally, we investigate some issues concerning WEC violation and human traversability in these time-dependent geometries.Comment: 12 pages latex, 3 figures, to appear in Phys. Rev.

Evolving Lorentzian Wormholes

Evolving Lorentzian wormholes with the required matter satisfying the Energy conditions are discussed. Several different scale factors are used and the corresponding consequences derived. The effect of extra, decaying (in time) compact dimensions present in the wormhole metric is also explored and certain interesting conclusions are derived for the cases of exponential and Kaluza--Klein inflation.Comment: 10 pages( RevTex, Twocolumn format), Two figures available on request from the first author. transmission errors corrected

The evolving Glasma

We extensively study the growing behavior of the energy and the pressure components depending on the space-time rapidity in the framework of the Glasma, which describes the early-time dynamics in the ultra-relativistic heavy-ion collisions. We simulate the Glasma solving the classical equations of motion in the SU(2) Yang-Mills theory and systematically investigate the dependence of the Glasma instability on the model parameters. We have checked that the transverse and longitudinal grid sizes in our simulation are large enough to handle cutoff effects under control. By comparing the numerical results from several initial conditions with different magnitudes of instability seed and also those with different wave-numbers for rapidity fluctuations, we clearly see that unstable modes dominantly grow up in the linear regime and we also confirm non-linear effects in the time evolution. To extract more detailed information on the evolving Glasma, we decompose the energy into the components in terms of rapidity wave-numbers. We observe an energy flow from low wave-number modes into higher wave-number modes due to non-linearity in the equations of motion. We find that the energy spectrum approaches an asymptotic scaling that is consistent with Kolmogorov's power-law form even in the expanding system of the Glasma.Comment: 29 pages, 18 figures, discussions on the non-linear regime and the power-law spectrum added, version accepted for publication in Nucl.Phys.
