ENVIRONMENTAL RESPONSIBILITY MODEL BASED ON ISO 14000 MANAGEMENT SYSTEMS
Catalina SITNIKOV
Management & Marketing , 2012,
Abstract: Worldwide corporations, as well as their stakeholders, are more conscious of the need for environmental management, SR behaviour, and sustainable growth and development. International Standards are becoming more significant for corporations to work towards common environmental management practices. ISO 14001 is the first and the broadest standard intended at a more responsible approach of corporations and the world’s most acknowledged framework for environmental management systems that assists corporations to better manage the effect of their activities on the environment. This article aims to study ISO 14001 implementation and its effects on the environmental responsibility. A model will be built, which covers the environmental management system, the components of organizational culture, being able to influence environmental standards implementation.
RESPONSIBILITIES IN MANAGEMENT OF TOURIST DESTINATIONS
Mirela MAZILU,Catalina SITNIKOV
Management & Marketing , 2010,
Abstract: 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.
Higgs Bosons, Quark Masses and Two Components of Cabibbo Angle  [PDF]
L. S. Sitnikov
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.412198
Abstract:

This paper discusses the discovery and study of the functional connection between the quark masses and their mixing parameters. That allowed calculating Cabibbo angle from the known values of the masses of two lower quarks. It has been established that mixing occurs not only among lower quarks, as it was known up to now, but the upper quarks, independently, do the same. A separate mixing angle is calculated for the latter. The existence of two Cabibbo angles, i.e. independent mixings of upper and lower quarks, is a strong argument in favor of models with not one, but with several Higgs bosons. Only taking into account such a link, it is possible to give the unified description of the dependence of the mass on the generation number for all charged fermions (except t-quark). It turns out that increments of values \"\" and N are linearly linked. (Here m and N—mass and generation number of fermion, A—common internal parameter of concerned fermions).

Whether the mean-field two-length scale theory of hydrophobic effect can be microscopically approved?
G. Sitnikov,S. Nechaev
Physics , 2005,
Abstract: We discuss the simple microscopic derivation of a hydrophobic effect. Our approach is based on the standard functional representation of the partition function of interacting classical particles and subsequent passage to collective variables (local densities of the solvent). We get an expression for the solvation free energy of solute molecule of any arbitrary shape and derive the nonlinear equation for the mean solvent density surrounding the solvated object. We pay a special attention to some inconsistencies between the microscopic consideration and the two-length scale mean-field theory of hydrophobic effect.
Magnetooptical Properties of Layer-by-Layer Deposited Ferromagnet—Dielectric Nanocomposites  [PDF]
Viktoria Evgenèvna Buravtsova, Elena Alexandrovna Ganshina, Sergey Alexandrovich Kirov, Yuriy Egorovich Kalinin, Alexandr Viktorovich Sitnikov
Materials Sciences and Applications (MSA) , 2013, DOI: 10.4236/msa.2013.44A003
Abstract:

The present work was initiated to investigate how technology of preparation of nanocomposites (Co45Fe45Zr10) Z(Al2O3)1-Z affects their magneto-optical (MO) properties. The spectral, magnetic field and concentration dependences of the transversal Kerr effect (TKE) have been studied either for bulk or layer-by-layer deposited nanocomposites within a wide range of the ferromagnetic (FM) phase concentrations and for various thicknesses of layers. It was found that the MO response of the layer-by-layer deposited nanocomposites with compositions inside the percolation interval differs essentially from the one of the bulk composites and depends on the layer thicknesses. With decreasing thicknesses of layers the percolation threshold has been shifted towards the lower contents of the FM phase. In addition, it has been established that the size and shape of the granules inside the nanocomposite layer also depends on the layer thickness as well as the microstructure of the layer-by-layer sputtered composites considerably differs from the microstructure of the bulk nanocomposite.

?Espectador en acción?: representación e identificación del pueblo/masa en El Chacal de Nahueltoro
Donoso,Catalina;
Aisthesis , 2010, DOI: 10.4067/S0718-71812010000100007
Abstract: el chacal de nahueltoro is not only one of the most important films in the chilean cinema as a whole, but it is particularly a key work in the so-called new chilean cinema. the present article attempts to explore the contradictions and tensions between people's representation and the audience appeal portrayed at the same time in the people's image displayed in the film. the analysis of the concept of "the "people" and the role of the spectator become more complex in a context where cinema is conceived as an element of social change, foregrounding the audience's active participation and its close relation to the film itself.
Tensión entre los ejes de lo clásico y lo contemporáneo en dos versiones escénicas de directores argentinos
Artesi,Catalina;
Cuadernos del Centro de Estudios en Dise?±o y Comunicaci?3n. Ensayos , 2010,
Abstract: in this work two scenic proposals released recently in the city of buenos aires are analyzed where the directors maintain in tension the axes of the classic and the contemporary in its traditional work updates. we talked about to cerco de numancia by miguel de cervantes saavedra who directed daniel suárez marzal in 2005 in the teatro nacional and the free version of the tartufo by moliere that in 2007 released guillermo cacace in his experimental theatre apacheta.
De la descentralización a la ?Nueva geometría del poder?
Banko,Catalina;
Revista Venezolana de Economía y Ciencias Sociales , 2008,
Abstract: the article offers an interpretation of the political dynamics developing in current venezuelan situation, starting from the process of decentralization initiated two decades ago and then examining the evolution of this experience up coming to the process of recentralization during hugo chávez frías management. also it is an analysis of the attempt of reform of the constitution to implement the ?socialismo del siglo xxi? (socialism of the 21st century), which imply an offer of territorial reorganization according to the guidelines of the ?nueva geometría del poder? (new geometry of power). this project was submitted to a popular referendum on december 2nd, 2007, in which the majority of the voters chose to reject the raised changes.
Factores de predicción del uso de soporte inotrópico en cirugía cardiaca. Hospital Rafael ángel Calderón Guardia, San José, Costa Rica, septiembre de 2005 a enero de 2007
Morales,Catalina;
Revista Colombiana de Anestesiología , 2008,
Abstract: background. in cardiac surgery, inotropic drugs are used frequently. it is important to anályze the effects of these drugs and the possibility to increase adverse outcomes when they are used incorrectly. the purpose of this study was to describe the inotropic requirement predictors. it pretends to reduce the use of these drugs in patients that do not need them.methods. we anályzed patient files who underwent surgery between september 2005 and january 2007 in the calderón guardia hospital in san josé, costa rica. they voere 119 patients. results. there was no difference in the use of inotropes rélated to age, sex, concomitant diseases, surgicál diagnosis, surgery perform or anesthesiologist. the previous history of cardiac infarction, the number of them or the time between the surgery and the last one were not related to the inotropic requirement. there was no relation between the american society of anesthesilogists score and the need of inotropic support; but a higher new york heart association score had a positive relation with the use of inotropes. the duration of the aortic clamp and the surgery time were also related with the need of inotropic support. the time of extracorporeal circulation had no relation with the need of inotropic drugs. there was a higher need for inotropic support in patients with a positive liquid balance and in patients with intraaortic balloon pulsation. the ejection fraction was a predictor of the need of inotropic drugs. conclusion. there are some variables related to a greater need of inotropics drugs.
