Quantum conversion

The electromagnetic momentum transferred transfered to scattering particles is proportional to the intensity of the incident fields, however, the momentum of single photons ($\hbar k$) does not naturally appear in these classical expressions. Here, we discuss an alternative to Maxwell's stress tensor that renders the classical electromagnetic field momentum compatible to the quantum mechanical one. This is achieved through the introduction of the quantum conversion which allows the transformation, including units, of the classical fields to wave-function equivalent fields.Comment: ICOAM 201

SUSTAINABILITY OR SUSTAINABLE DEVELOPMENT A RESPONSIBILITY OF THE ENVIRONMENTAL SPECIALISTS

The community development has in view the encouragement and the involvement of the human resources management on the track meant for the individual and social development. The quantification of the human capital offers the necessary information for the design of a strategy oriented towards resources for the organisational development. In Romania, according to the information regarding the dynamic of the economic indicators, we notice a positive economic growth, but the inflation constitutes a problem from an internal as well as external point of view. By analysing the development performances of the last years, we discover progresses in innovation, research, in the entrepreneurial development of the company, in the degree of occupation of the human resources and the economic cohesion, in the sustainable economic development and in the liberation of the market. Indicators like the number and density of the population, the territorial distribution of the population, the structure of the population on genders, age groups, residential environments, ethnical structure, religion, social and economical structure and education, as well as the indicators referring to the housings shape a complete picture of the human potential development according to the European standards. Through the increase in competitiveness and of the globalisation, the workforce market suffers certain transformations from the integration point of view together with the other social sectors. The evolution of the society determines the building of a society and economy based on the knowledge according to the European social model values, in the field of the human resources management they will contribute to the social integration, to the development of new changes at the level of social dialogue. The last decades got us used to the reality of the “leaps”. In the most varied fields of the human’s life, we are the witnesses to some triumphal mutations and stupefying progresses that are taking place imperatively and simultaneously. Is there really a price to pay for the progress? Absorbed with a delirious speed in some kind of a time tunnel, the human being is forced to accept the idea that frontier of the impossible became extensible in all its meanings. The undreamed of and fantastical chances become common places from one day to another. These are the matters and thoughts tried to be answered in the lines of this articleHuman resources,management, education, ethic, damages, natural environment, responsibility, sustainable development

The eigenpairs of a Sylvester-Kac type matrix associated with a simple model for one-dimensional deposition and evaporation

A straightforward model for deposition and evaporation on discrete cells of a finite array of any dimension leads to a matrix equation involving a Sylvester-Kac type matrix. The eigenvalues and eigenvectors of the general matrix are determined for an arbitrary number of cells. A variety of models to which this solution may be applied are discussed.Comment: 7 pages, no figure

THE IMPERATIVE OF INVOLVING PUBLIC AUTHORITIES (CENTRAL AND LOCAL) IN DEVELOPING SUSTAINABLE TOURISM

Despite tourism is one the activities which had a spectacular development in the last decades and although our country has a notable tourism potential, Romanian local and central public authorities` interest in this direction is very low. Apart from being a scientifically approach, the paper acts as a stimulant for local and central public authorities that promote sustainable tourism. The general trend in tourism evolution and in the attempt to strengthen its position within sustainable economic development process is to analyzing the tourism phenomenon at global level. This proves that at the moment, tourism is one of the most dynamic economy sectors, constantly dealing with changes and positive evolutions. Discovering the trends, the challenges facing international tourism in the third millennium, the determinant factors that will influence global tourism activities in the future, tourism categories that will grow fast in the first part of the 21st century, all must be taken into consideration by central and local public authorities when developing policies, strategies, plans and programs for developing tourism.sustainable tourism, local public administration management, sustainable tourism, economic integration, local and regional development.

Exact energy spectrum of a two-temperature kinetic Ising model

The exact energy spectrum is developed for a two temperature kinetic Ising spin chain, and its dual reaction diffusion system with spatially alternating pair annihilation and creation rates. Symmetries of the system pseudo-Hamiltonian that enable calculation of the spectrum are also used to derive explicit state vectors for small system sizes, and to make observations regarding state vectors in the general case. Physical consequences of the surprisingly simple form for the eigenvalues are also discussed

The Tourist Experience and the Challenges of the Environment

Like any other human activity, without containing intentional elements, tourism, being a consumer of space and tourist resources, participates implicitly in the degradation and the pollution of the environment of the tourist potential, either through the direct pressure of the tourists on the landscape, the flora and the fauna, or on other tourist objectives which can be damaged partially or totally, or through the wrong conception of revaluation and equipment of some areas, points or tourist objectives. The natural environment probably represents the greatest wealth of the Romanian tourism. The protection of the environment is thus crucial for tourism. The tourist experience has demonstrated, in time, that, regardless of the type of tourism people practise, a series of impacts results and they are felt by the society as well as by the natural environment. The development of tourism in a certain area must not affect the social and economic interests of the resident population, nor of the environment, and, most of all, of the natural resources which constitute the main attraction together with the historic and cultural sites.tourism, impact, destination, sustainable development, experience

RESPONSIBILITIES IN MANAGEMENT OF TOURIST DESTINATIONS

Over the past six decades, tourism has experienced continued growth and diversification to become one of the largest and fastest growing economic sectors in the world. Over time, more and more destinations have opened up and invested in tourism development, turning modern tourism into a key driver for socioeconomic progress. Tourism has become one of the major international trade categories. Today, the export income generated by international tourism ranks fourth after fuels, chemicals and automotive products. For many developing countries, it is one of the main income sources and the number one export category, creating much needed employment and opportunities for development. There are many roles and various responsibilities in the management of the tourist destination and marketing. These are lead in different ways, in different countries, but, in general, they are divided among the national, regional and local levels. The national level is normally responsible for more strategic roles, while the local level is responsible for the operational elements.tourism, sustainability, re-launching strategy

DEMOGRAPHIC, SOCIAL, ECONOMIC AND GEOGRAPHIC FEATURES – SHAPING FACTORS OF THE TOURIST MARKET

One of the major themes which have more and more importance at a European level, but also at a national level, is the demographic evolution and its effects in the different fields of the social and economic life. The demographic trends which affect Romania, emphasized in the demographic prognoses, require a more complex approach, from the perspective of the development projects which the local authorities are initiating, within the operational programs, based especially on the objectives of the Regional Operational Program – REGIO. In order to clarify the connection between demography and development, between demography and tourism, we must underline the analysis of the demographic situation and the demographic prognoses on a medium and long term, which serve to the correct foundation of the plans and development strategies, regardless of the field of life and social activity, so exposed to the current metamorphoses.demography, tourism, tourist market, development, strategy
