Energy and time as conjugate dynamical variables
The energy and time variables of the elementary classical dynamical systems
are described geometrically, as canonically conjugate coordinates of an
extended phase-space. It is shown that the Galilei action of the inertial
equivalence group on this space is canonical, but not Hamiltonian equivariant.
Although it has no effect at classical level, the lack of equivariance makes
the Galilei action inconsistent with the canonical quantization. A Hamiltonian
equivariant action can be obtained by assuming that the inertial parameter in
the extended phase-space is quasi-isotropic. This condition leads naturally to
the Lorentz transformations between moving frames as a particular case of
symplectic transformations. The limit speed appears as a constant factor
relating the two additional canonical coordinates to the energy and time. Its
value is identified with the speed of light by using the relationship between
the electromagnetic potentials and the symplectic form of the extended
phase-space.Comment: Replaced to write Eqs. (34), (35) in the general for
Public and private affairs marketing in rural tourism development
In Romania, the agro and rural tourism started as potential sources of living and become an alternative for the classic tourism. As we rise up on the presented papers in 2003, even if there is a significant development of the rural tourism, it is not very attractive to the Romanian people. The study made on County Dambovita area, shows that an important reason of the poor attractiveness of agro-tourism in mountains rural area is the les proper marketing of the services. Based on these conclusion and taking advantages on the public administration area, it was started a program of public and private marketing of rural tourism. The main stages of the programme were: 1) the evaluation of specific indicators of rural tourism like staying overnights, net using capacity in function and quality of provided services; 2) provide information and advertise the area facilities and natural environment using the public administration infrastructure; 3) make the link between the owners of tourism capacities and public servants by a briefly marketing training; 4) re-evaluation the indicators mention above. The results of the programme implementation prove that the public and private marketing, used in partnership by local authorities and of rural tourism services providers, could be a tool of better development. Never the les, the win-win situation rise up from the benefit of general economic development of the area obtained due to a larger flux of domestic and foreign tourists.tourism, development, public, private affairs, marketing
Education & business management
Romania, as well as other countries from the East Europe, is crossing a transition period, due to the political changes from 90’s years. At the same time there are fundamental modifications in all socio-economic areas. One of the most important domains is the education sector, at all his levels but especially at the academic ones. The connections between the academic life and business environment could be considered as fundamental issue of the economic development, linkage of the national values to the Europeans, integration facilitator. From this point of view the education management has a very important role and it has to be related to the expectation of the business environment. To be able to offer the best product for on the labor market, the academic management has to be designed according with the business management principles. The business environment was forced to accept and implement the market economy fundamentals to survive under the new conditions. The orientation of the business to the European Union is shows by the trends of the exports and imports significant increased in the last years. New questions rise from the future evolution taking into account the enlargement of the European Union and the Romanian integration expected for 2007. In our opinion the educational and academic sector passed the first evolution step represented by the apparition and development of the private sector and the connection with the European and international similar institution. These tow direction open a new window for changing ideas and organize the education sector on new basis. The enlargement process of the European Union will make the education management face with new challenges. We consider that the cybernetic approach of the linkage between education management and business management could offer viable solution for both sectors and socio-economic development.education, business, knowledge, management
System composite of the triplet’s of strategic overview – revised fundamentals
The STIQE 2004 paper presents the identified triplets at macro and micro level of the socio-economic system. Through the important triplets identified are the following: European Union (UE) – State Members (SM) – European Citizens (ECz); European parliament will (PW) – national commitment (NC) – personal desire (PD); sustainable development(SD) - environment protection(EP) - quality of life(QL); economics(EC) – social climate(SC) – politics(P); material resources(MR) – financial resources(FR) – human resources(HR); life security (peace)(LS) – food security (survival)(FS) – environment security(ES); agriculture development (AD) - industrial development (ID) – infrastructure development (IsD); jobs/salaries (JS) – affordability/ expenses (AE) - quality of life (QL). It was also proposed a way of the triplets identification, a system to organize and link them on two dimensions: micro and macro level, and to get possible final structures by linking the two plans. The output, through a geometrical approach, has to be a system of interconnected triplets able to provide potential effects on the whole by action (modification) one point, than could be use for national strategies design and effects estimation. According with the opinions expressed at the conference we decide to revise the fundamentals of the theory. So, there were settled some criteria of knots identification, triplets assemble and plans definition. The main delimitation are euro/national areas, micro/macro levels and socio/economic approaches. The revised fundamentals are based on a more structured view, able to conduct us to a better triplets assembly as a whole. Also, the selection of the knots is made more carefully taken into account the future step of their evolution and dependences expressed by mathematic functions. At the same time there were identified potential factors of knots influence. It is a step back on the theory development, but it allows a better analysis and structuring of the elements taken into account, that could be a crucial decision in reaching the right composite of the system.sustainable development, triplets, overview, strategy, fundamentals
