Una aplicación de experimentos de elección para identificar preferencias locales por opciones de conservación y desarrollo en el extremo sur de Chile
Cerda,Claudia;
Bosque (Valdivia) , 2011, DOI: 10.4067/S0717-92002011000300011
Abstract: this study uses a choice experiment (ce) to estimate economic values of environmental services that are not traded in markets, provided by forests of navarino island, magallanes and antártica chilena, chile. this is a pristine area with low level of economic development. it includes temperate forests of global interest to be preserved. however, development projects can threaten this condition. the central research question is: to know the economic preferences of the local community of navarino for the environmental services provided by forests on the island. scenarios with different levels of attributes and touristic development were analysed using a ce (n = 230). as most of the development options for navarino include some loss of environmental services due to the pristine condition of the place, increases in income/year were offered as monetary compensation (willingness to accept). participants’ decisions about future development and conservation strategies were influenced by the following attributes: scenic beauty threatened by levels of tourism infrastructure, access restrictions due to both nature conservation and private interests, visits of the hummingbirds (sephanoidessephanoides) and protection for an endemic moss (tayloria mirabilis). participants favoured a model of low impact development, represented by small-scale tourism. this research illustrates the application of a methodology to incorporate citizens preferences in conservation strategies.
El negativo de la epilepsia: un ejercicio intelectual de ciencia-ficción
Fernanda Cerda
Cuadernos de Neuropsicologia , 2007,
Abstract: Many have been the efforts throughout the history, for the study and treatment of Epilepsy, which has been categorized generally, as a pahological manifestation of a disease. In this essay , the author pretends to create a theoretical exersise space, destined to think of this admitted "pathology" more like a biological protective function with a certain value. The arguments explained, aim to the fact that Epilepsy is not necessarily a manifestation of death, damage or deterioration of neuronal or cognitive functions.
La Universidad Desafiada (book review)
Fernanda Cerda
Cuadernos de Neuropsicologia , 2007,
Abstract: No puedo menos que comenzar se alando que al momento de leer por primera vez este libro tuve la sensación inquietante de que algo muy potente se escondía tras esas palabras. Tuve que releerlo para asegurarme que nada se me había pasado. Y tras esa segunda lectura caí en la cuenta que, en mi historia de lecturas, nunca había llegado a mis manos nada semejante.Contingente, osada, muy directa y tremendamente consistente, “La universidad desafiada” constituye en esencia una contestación sólida e informada a lo que algunos han dado en denominar postmodernismo, constructivismo o deconstruccionismo.
Una aplicación de experimentos de elección para identificar preferencias locales por opciones de conservación y desarrollo en el extremo sur de Chile An application of choice experiments to identify local preferences for conservation and development options at the extreme south of Chile

Abstract: Este estudio utiliza un experimento de elección (EE) para estimar valores económicos de servicios ambientales no transados en mercados, proporcionados por bosques de la isla Navarino, región de Magallanes y Antártica Chilena, Chile. ésta es un área prístina con bajo nivel de desarrollo económico. Contiene bosques templados de interés mundial para ser conservados. Sin embargo, proyectos de desarrollo pueden amenazar esta condición. La pregunta central de investigación fue: conocer las preferencias económicas de la comunidad local de Navarino, por los servicios ambientales proporcionados por los bosques de la isla. Para ello se analizaron escenarios con diferentes niveles de atributos y de desarrollo turístico mediante un EE (n = 230). Como la mayoría de las opciones de desarrollo para Navarino incluyen alguna pérdida de servicios ambientales debido a la pristinidad del lugar, se ofrecieron incrementos en la renta anual como compensación monetaria (disposición a aceptar). Las decisiones de los participantes sobre futuras estrategias de desarrollo y conservación fueron influenciadas por los siguientes atributos: belleza del paisaje amenazada por niveles de infraestructura turística; restricciones de acceso a la naturaleza debido a intereses privados y de conservación, visitas de los picaflores (Sephanoides sephanoides) y protección para un musgo endémico (Tayloria mirabilis). Los participantes favorecieron un modelo de desarrollo de bajo impacto, representado por turismo a baja escala. Esta investigación ilustra la aplicación de una metodología que permite incorporar en las estrategias de conservación las preferencias de los ciudadanos.

On $k$-Fibonacci sums by matrix methods
Gamaliel Cerda
Mathematics , 2014,
Abstract: In this paper, some $k$-Fibonacci and $k$-Lucas with arithmetic indexes sums are derived by using the matrices $R_{a}=\left[ \begin{array}{lr} L_{k,a} & -(-1)^{a} \\ 1 & 0 \end{array}\right]$ and $S_{a}=\frac{1}{2}\left[ \begin{array}{lr} L_{k,a} & \Delta_{a} \\ 1 & L_{k,a} \end{array}\right]$, where $\Delta_{a}=L_{k,a}^{2}-4(-1)^{a}$. The most notable side of this paper is our proof method, since all the identities used in the proofs of main theorems are proved previously by using the matrices $R_{a}$ and $S_{a}$, with $a$ an natural number. Although the identities we proved are known, our proofs are not encountered in the $k$-Fibonacci and $k$-Lucas numbers literature.
ARMONIZACIóN DE LOS DERECHOS DE AUTOR EN LA COMUNIDAD ANDINA: HACIA UN NUEVO RéGIMEN COMúN
Cerda Silva,Alberto;
Ius et Praxis , 2011, DOI: 10.4067/S0718-00122011000200009
Abstract: the andean community, which started late in the sixties, is one of the main processes of integration in latino america, that currently involves bolivia, colombia, ecuador, and peru. in 1993, as part of the process of integration, the andean community adopted the decision 351 that sets forth a common regime on copyright and neighboring rights. that regime was a first step in the legal harmonization on that matter for those countries, which still preserve their domestic law, in so far as it does not infringe the provisions of the decision. however, the efficiency of the common regime as an instrument for harmonization within the andean community has been reduced because of the course of the years, challenges of new technologies, and emerging bilateralism, among other causes. at the same time, even when tolerated by the common regime, significant differences between the domestic law of country members obstacle the proper functioning of the internal, particularly en el context of digital economy. those circumstances made explicit the need for updating the common regime in order to facilitate the integration of the andean community. this article describes briefly the decision 351, and then analyzes the main limitations of the in force common regime in order to identify the issues that require an urgent legal harmonization within the andean community. then, this article suggests some those issues on which the andean community must emphasize its harmonization when updating the common regime -copyright scope, exceptions and limitations, public domain, and copyright enforcement- and makes some recommendations on strategies to achieve that legal harmonization.
Mecanismos de Control en la Protección de Datos en Europa
Cerda Silva,Alberto;
Ius et Praxis , 2006, DOI: 10.4067/S0718-00122006000200009
Abstract: the article considers the diverse elements on which the normative approach in the matter of public protection, processing of personal data-such as the scope of the application of the law, the governing principles of the norm, the rights conferred to the data subject and the responsibility initiated in the process of the data have taken place. immediately, the article digs deeper into the diverse mechanisms of control adopted in europe, concluding that the recognition and promotion of self-control mechanisms do not guarantee an adequate level of protection. therefore it is necessary to make a control authority available; a public organism which will promote and inform the community about the appropriate legislation of personal data processing; to control the completion of the norm and to sanction its infraction, or rather to insist on the sanction of the transgressor. such institutions contribute to the effective implementation of a coherent public policy on a democratic state that promotes the conditions guaranteeing the total development of the people
LICENCIAS OBLIGATORIAS POR RAZONES DE SALUD PúBLICA EN CHILE: UN ANáLISIS COMPARATIVO CON EL ACUERDO SOBRE LOS ADPIC

Abstract: in implementing its various international agreements on intellectual property, chile has amended its industrial property act, which regulates the patent system, by recognizing the patentability of pharmaceutical products (1991) and establishing a scheme for granting compulsory licenses based on reasons of public health (2005). this article describes and analyses the rules adopted about compulsory licenses on pharmaceutical patents in order to establish whether it meets the standard promoted by the world trade organization in the agreement on trade related aspects of intellectual property rights (trips) and takes advantages of flexibilities provided by international agreements, especially those resulting of the doha declaration.

HOLISTICA: UNA LUZ VERTEBRADORA PARA EL CAMBIO
Cerda E,Gamal Abdel;
Estudios pedagógicos (Valdivia) , 1998, DOI: 10.4067/S0718-07051998000100010
Abstract: a pervading anxiety marks our society. men and women find themselves disturbed by permanent and rapid changes. the result can be disenchantment, abulia, or unrestraint. often the result is an overinsistence on rights, with no acknowledgement of the duties that accompany them. some people opt for personal happiness, placing a high value on pleasure in order to "be themselves". others choose to escape, to be self-complacent, to alienate themselves from the world. indeed, some consider themselves incapable of finding integration with the world. a look back at history, though, shows that this crisis is not new and that philosophers, scientists, and educators have already formulated ideas and proposals on how to face such times. their thoughts form a common body of ideas that act as a key bone or an axic which is a global, total, holistic paradigm. what they have said in response to their circumstance is a broad, integrated and unifying answer for our own age. education must pick up these ideas, taking advantage of the current educational reform.
